    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
or site rights in ten cities in North America comprising approximately
2.9 million square feet.



    We offer network services to meet our customers' demands and 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 and
additional colocation facilities that we intend to acquire, we intend to provide
additional network services such as Internet data centers, applications hosting,
electronic commerce support and web hosting. We also 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 six major population centers in Brazil,
      Venezuela, Bermuda 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. In addition, we intend to extend our
      network to Buenos Aires through undersea and/or terrestrial routes.


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 or site rights in ten North American cities. The
    initial purchase price for these acquisitions is $176.5 million, of which
    $26.3 million is payable in our Subordinate Voting Shares valued at the
    inital public offering price.


RECENT SIGNIFICANT BANDWIDTH TRANSACTIONS


    - KPNQWEST. We recently signed an agreement with KPNQwest to sell capacity

Subordinate Voting Shares for total consideration of approximately
$250 million.



    We have entered into a letter of intent, in connection with a colocation and
bandwidth cooperation arrangement, to exchange $100 million of our Subordinate

definitive documentation.

investors is less than the initial public offering price. Each of these
strategic investors has agreed not to dispose of or hedge any of their shares
acquired in these private transactions during the period from the date of this
prospectus continuing through 12 months after the date of this prospectus,
except with the prior written consent of Goldman, Sachs & Co., Donaldson,

                             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 $700 million of senior notes that we currently
      intend to issue 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 $548 million;


    - our acquisition of all outstanding stock of GlobeNet;


    - the issuance of $700 million of senior notes that we currently intend to
      issue 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
      $175 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,

                                       7
<PAGE>
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 $140 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;


    - obtain required regulatory approvals;


    - 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;

                                       11
<PAGE>
    - unforeseen engineering, environmental or geological problems; and

    - 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

                                       12
<PAGE>
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 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

                                       13
<PAGE>
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 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

      us of approximately $548 million;


    - our acquisition of all outstanding stock of GlobeNet;


    - the issuance of $700 million of senior notes that we currently intend to
      issue 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; and


    - the completion of the $565 million 360ATLANTIC credit facility, of which
      $175 million has been drawn.



    The initial annual interest expense on the $700 million of senior notes to
be issued in concurrent debt offerings is $98 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 $140 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;

                                       19
<PAGE>
    - conditions in the telecommunications industry;

    - 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 currently intend to issue $700 million of debt in the concurrent debt
offerings. The closing of this offering is not conditioned on the closing of
either of the debt offerings. If we do not issue that debt because of market
conditions or because terms acceptable to us are not available, we will need to
raise additional capital to complete our network and other items described under
"Use of Proceeds." We may not be able to raise this capital or raise this
capital on terms acceptable to us.



    A portion of our investment in 360ATLANTIC was funded from our recently
completed private sale of our equity securities. The indebtedness to finance
that project has been or will 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

                                       20
<PAGE>
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.

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 we currently intend to consummate, are estimated to be approximately
$1.2 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
<PAGE>
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 applications have been 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
729,000,000 Subordinate Voting Shares outstanding, or approximately 736,000,000
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 memorandum of association includes 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) 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 $548 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 $682 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.


    The closing of this offering is not conditioned on the closing of either of
the debt offerings. If we do not issue that debt because of market conditions or
because terms acceptable to us are not available, we will need to raise
additional capital to complete our network and other items described in this
section. See "Risk Factors--Additional Borrowings Required."


    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 729,416,907 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 $1,111,718,000 or $1.37 per share. This represents an immediate
increase in consolidated net tangible book value of approximately $0.84 per
share to the existing shareholders and an immediate dilution of $11.63 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.

    The following table sets forth our consolidated cash and capitalization as
of December 31, 1999 on an actual basis, as adjusted to give effect to:

      issue 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

                            SELECTED FINANCIAL DATA

    The selected financial data presented below 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 selected historical financial data presented 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 $700 million of senior notes that we currently
      intend to issue in the concurrent debt offerings;


    - the interest expense on the $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 $548 million;



    - our acquisition of all outstanding stock of GlobeNet for approximately
      $642 million of our Subordinate Voting Shares;



    - the issuance of $700 million of senior notes that we currently intend to
      issue 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
      $175 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 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 $140 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
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, 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 completed the
transfer to Urbanlink of 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 LLC ("IC LLC") in a cash and share
exchange transaction, as a result of which CN acquired 14,920,866 Subordinate
Voting Shares (to be reduced to 12,307,692 shares based on an assumed initial
public offering price of $13 per share). 360-CN is now a wholly owned subsidiary
of Worldwide Fiber Networks Ltd., which is a wholly owned subsidary of ours, and
IC LLC is now a wholly owned subsidiary of Worldwide Fiber IC Holdings, Inc.,
which is a wholly owned subsidiary of Worldwide Fiber Networks Ltd. Concurrent
with the closing of the offering, we will acquire the remaining 25% minority
interest in Worldwide Fiber (USA) Inc. ("360-USA") from Mi-Tech
Communications, LLC ("Mi-Tech") in exchange for 24,000,000 Subordinate Voting
Shares. Worldwide Fiber Networks Ltd. has 100% of the equity participation and
90% of the voting control of 360-USA, with the other 10% of voting control held
by another subsidiary of ours, Worldwide Fiber Finance Ltd.

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 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 LLC.


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-

                                       40
<PAGE>
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 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.

                                       41
<PAGE>
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 capital costs of completing and lighting our network
      of 10,600 route miles in Europe will be $360 million.


    - 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 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 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 $175 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 that we have
      agreed, subject to execution of definitive agreements, to acquire, we plan
      to issue equity and use up to $150.2 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

                                       42
<PAGE>
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.

    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 $700 million 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. The closing of this offering is
not conditioned on the closing of either of the debt offerings. If we do not
issue that debt because of market conditions or because terms acceptable to us
are not available, we will need to raise additional capital to complete our
network and other items described under "Use of Proceeds." We may not be able to
raise this capital or raise this capital on terms acceptable to us.



    In addition, we have accepted an underwritten commitment from The Chase
Manhattan Bank and an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation to provide up to $1.0 billion of financing under a senior credit
facility. This commitment is subject to negotiation of definitive documentation
and other closing and lending conditions. The amounts borrowed under this
facility will be required to be used in compliance with restrictions contained
under our indentures. There can be no assurance that this credit facility will
be entered into in a timely fashion or at all.


    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

                                       43
<PAGE>
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 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.

                                    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 or site rights in ten cities in North America and site rights in five
other North American cities comprising approximately 2.9 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 and 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 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. In addition, we intend
to extend our network to Buenos Aires through undersea and/or terrestrial
routes.


    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

                                       46
<PAGE>
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 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 and
additional colocation facilities that we intend to acquire we intend to provide
additional network services such as Internet data centers, applications hosting,
electronic commerce support and web hosting. We also 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.

                                       47
<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. In
addition, we intend to extend our network to Buenos Aires through undersea
and/or terrestrial routes.


    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

                                       48
<PAGE>
Telewest in the United Kingdom. Further, we intend to continue to explore
strategic opportunities 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, Rupert Murdoch, Chairman
and Chief Executive Officer of News 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 Strategic Advisory Committee, 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 and the investment in us of divine interVentures, inc. are examples 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.

                                       49
<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, Madrid, 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,

                                       50
<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 736 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 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
$56.8 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 or site rights in ten cities totalling
approximately 2.9 million square feet. These facilities are expected to be
completed by the end of 2001. In addition to the initial purchase price of
$176.5 million, of which $26.3 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 are exploring opportunities to provide colocation facilities in Europe so
that we will have arrangements in place in major European cities to develop and
provision colocation facilities by the time we activate our network in Europe.


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

                                       53
<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.


    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

                                       55
<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 granted affiliates of PSINet an indefeasible right of use for bandwidth
capacity between Vancouver and Chicago, and have agreed 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.

    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

                                       56
<PAGE>
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 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

                                       57
<PAGE>
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 building 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.

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

                                       58
<PAGE>
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.

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

                                       59
<PAGE>
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
Ledcor Industries construction project 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

                                       60
<PAGE>
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 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

                                       61
<PAGE>
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 are building a NOC located in
Dublin, Ireland, which is scheduled to be completed in November 2000.


    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.

ARRANGEMENTS WITH RESPECT TO DIRECTORS' NOMINATIONS


    Under the terms of a shareholders' agreement among shareholders holding more
than 99% of our shares immediately prior to the completion of the offering, we
agreed to set the maximum number of our board of directors at seventeen members
and to nominate as directors:



    - one designee from each of our private equity investors, namely affiliates
      of Tyco International Ltd., Providence Equity Partners Inc., DLJ Merchant
      Banking Partners II L.P. ("DLJ") and GS Capital Partners III, L.P.
      ("GS Capital"), so long as, in each case, each investor continues to hold
      a prescribed number of our Subordinate Voting Shares;


    - Mr. Maffei together with two of his additional designees so long as he
      remains our Chief Executive Officer; and

    - the balance from designees of a subsidiary of Ledcor Inc.


    Under the terms of the shareholders' agreement, each shareholder other than
DLJ and GS Capital also agreed to vote for the foregoing nominees other than the
respective designees of DLJ and GS Capital in connection with their election to
our board of directors.


EMPLOYMENT AGREEMENT

    Mr. Maffei became our Chief Executive Officer effective January 18, 2000
pursuant to an employment agreement entered into on December 22, 1999. The
employment agreement has a term ending on June 30, 2003, subject to annual
extensions thereafter. Mr. Maffei will receive an initial salary of $150,000 per

BOARD COMMITTEES

    Upon the completion of the offering, our board of directors will have two
standing committees: an Audit Committee and a Compensation Committee. All of the
members of our Audit Committee will be persons who are not our officers or
employees or officers or employees of any of our affiliates. The Audit Committee
will select and engage, on our behalf, the independent public accountants to

scope of the annual audit. The Compensation Committee will establish
remuneration levels for our senior officers and will perform such functions as
provided under our stock option plan.

COMPENSATION OF DIRECTORS

    The independent directors, other than those designated by our private equity
investors, will each receive a grant of options to purchase 25,000 Subordinate
Voting Shares at fair market value at the time of their appointment and an
annual grant of an additional 10,000 options each year thereafter, all of which
options will vest over two years.

</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. In addition, the aggregate number of Subordinate Voting Shares
reserved for issuance to any one person must not exceed 5% of our issued and
outstanding Subordinate Voting Shares. 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

                                       69
<PAGE>
that are awarded by our compensation committees will comply in all respects with
Section 422 of the U.S. Internal Revenue Code.

    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.

                                       70
<PAGE>
    TRANSFERABILITY


    Unless otherwise determined by our compensation committee, subject to
receipt of necessary regulatory approvals, 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


    Upon receipt of necessary regulatory approvals, 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 SHAREHOLDERS


    The following table describes the beneficial ownership of our Class C
Multiple Voting Shares and Class B Subordinate Voting Shares as of April 14,
2000 by (i) each person or company known by us to own more than 10% of our
Class C Multiple Voting Shares or Class B Subordinate Voting Shares, and
(ii) all of our directors and officers as a group. As of April 14, 2000, there
were 81,840,000 Class C Multiple Voting Shares and 57,629,600 Class B
Subordinate 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.

                  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 March 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.

                                       74
<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 24,000,000 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
72,000,000 of our Class C Multiple Voting Shares. In addition, we assumed
defined rights and obligations under 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.


    On August 4, 1999, we reached an agreement with Ledcor whereby Ledcor would
construct communications shelters on various segments of our network builds for
approximately $4.3 million.


    CANADIAN TELECOMMUNICATIONS ARRANGEMENT


    On April 17, 2000 we concluded a series of transactions to transfer our
Canadian telecommunication transmission facilities and certain related
facilities to Urbanlink. The assets were transferred at fair market value which
was approximately $16 million. The consideration for the transfer was the
non-voting participating shares described below. For accounting purposes the
transfers were undertaken at carrying value which was approximately
$6.4 million. 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 owns
66 2/3% of the voting non-participating shares and 49% of the non-voting
participating shares of the holding company which wholly owns Urbanlink, and we
own 33 1/3% of the voting non-participating shares and 51% of the non-voting
participating shares of that company. The share ownership of Ledcor, including
the controlling interest owned by David and Clifford Lede, directors of
360NETWORKS, is described under "Principal and Selling Shareholder." To acquire
its non-voting participating shares, a subsidiary of Ledcor contributed
Subordinate Voting Shares of 360NETWORKS. Concurrent with the closing of the
arrangement we entered 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)


                                       75
<PAGE>

that eliminates the requirement that Canadian telecommunications carriers be
owned and controlled by Canadians. Although the value of future transactions
under these agreements cannot be ascertained now, the agreements have been
negotiated to reflect fair market terms. We will contribute certain
telecommunications assets under construction to Urbanlink in the future and a
subsidiary of Ledcor will contribute additional Subordinate Voting Shares at
values to be determined in the future.


    LEASES


    Ledcor leases our facilities in Toronto to us for approximately $881,000 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
LLC, as a result of which we issued to CN 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. Based upon the assumed initial
public offering price of $13 per share the number of Subordinate Voting Shares
issued to CN will equal 12,307,692. 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

                                       76
<PAGE>
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. Mr.
Olsen and Madison Square have exercised their rights to participate in certain
private equity sales to be made by Ledcor concurrently with the consummation of
this offering.

                          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

                                       78
<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 by them, and which are subject to the Transfer
Restriction Agreement, 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 follow up offer to
be made to all holders of Subordinate Voting Shares if the sale had been of
Subordinate Voting Shares rather than Multiple Voting Shares.



    One circumstance where securities legislation 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 Memorandum of Association currently authorizes us to issue
100,000,000,000 Class A Non-Voting Shares, 100,000,000,000 Class B Subordinate
Voting Shares, 100,000,000,000 Class C Multiple Voting Shares and

reorganize our capital will occur resulting in the share capital structure
described above:



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


                                       79
<PAGE>

    - the Series A Non-Voting Preferred Shares will be converted into 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 their share conditions 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 redesignated as
      Multiple Voting Shares and their share conditions will be amended to
      provide the holders with ten votes per share, and



    - a class consisting of 500,000,000,000 Preferred Shares, issuable in
      series, will be authorized and created.

transactions an aggregate of approximately 58.3 million Subordinate Voting
Shares for total cash consideration of approximately $608.5 million. The average
price per share paid or agreed to be paid by these strategic and private
investors is 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. Ledcor is in discussions to, and may agree to, issue
Subordinate Voting Shares to a limited number of additional private and
strategic investors in transactions which are expected to close shortly after
the closing of this offering. Those investors include certain financial
institutions and strategic investors that may buy notes in our concurrent debt
offerings. If all of these transactions are completed, Ledcor will sell
approximately 23 million Subordinate Voting Shares for total consideration of
approximately $250 million


REGISTRATION RIGHTS


    Substantially all of our shareholders, with the exception of Worldwide Fiber
Holdings Ltd., Ledcor Limited Partnership and MacKenzie Partners LLC, have
registration rights, including 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, substantially all
of our shareholders have agreed that they will not transfer their shares for at
least 12 months. See "Shares Eligible for Future Sale."

                        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 729,416,907 Subordinate Voting
Shares outstanding and outstanding options to purchase 52,501,680 Subordinate
Voting Shares, assuming no additional option or warrant grants or exercises
after March 17, 2000. The great majority of the 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 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 and Worldwide Fiber Holdings Ltd.--24 months;



    - our strategic investors, certain shareholders of GlobeNet (in connection
      with their strategic investment), Mr. Maffei, Madison Square, 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 7,294,169 shares immediately
      after this offering; and


                                       81
<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 options granted prior to
July 21, 1998, under 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 have applied to applicable Canadian securities regulatory authorities
to permit after six months sales of Subordinate Voting Shares issued upon
exercise of options granted prior to the offering 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.

                                       83
<PAGE>
    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

                                       84
<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.

                                       85
<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

                                       86
<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

                                       87
<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

                                       88
<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

                                       89
<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.

                                       90
<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

                                       91
<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.

                                       92
<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.

                                       93
<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

                                       94
<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."

                                       95
<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

                                       96
<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.

12% per annum. Interest is payable each August 1 and February 1, commencing on
February 1, 2000.

the 1999 Notes and (b) any subsequent notes issued under the 1999 Indenture,
remains outstanding after the occurrence of the redemption and (2) we may redeem
the 1999 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 1999 Notes will have the right to require us to repurchase all or any part of
that holder's 1999 Notes at a purchase price in cash equal to 101% of their
principal amount, plus accrued and unpaid interest to the date of purchase.

    COVENANTS.  The 1999 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;

    - 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.

1998 NOTES

    GENERAL.  The 1998 Notes are senior obligations of ours, limited to
$175 million in principal amount and mature on December 15, 2005. The 1998
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

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

2004....................................................       100.000%
</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

                                       99
<PAGE>
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,

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 $175 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

                                      100
<PAGE>
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 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.


PROPOSED CREDIT FACILITY



    We have accepted an underwritten commitment from The Chase Manhattan Bank
and an affiliate of Donaldson, Lufkin & Jenrette Securities Corporation to
provide up to $1.0 billion of financing under a senior credit facility. This
commitment is subject to negotiation of definitive documentation and other
closing and lending conditions. Amounts borrowed under this facility will be
required to be used in compliance with restrictions contained under our
indentures. There can be no assurance that this credit facility will be entered
into in a timely fashion or at all.

         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 (1980), 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

                                      102
<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

                                      103
<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.

                                      104
<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 (1980), 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 generally is reduced
to 5%.



    Canada does not currently impose any federal 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.

    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, the Underwriters may purchase, over-allot
or effect transactions on The Toronto Stock Exchange, on the Nasdaq National
Market, in the over-the-counter market or otherwise, which stabilize or maintain
the market price of the Subordinate Voting Shares at a level that might not
otherwise prevail on the exchange. 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


                                      107
<PAGE>

exist in the open market. If these activities are commenced, they may be
discontinued by the Underwriters at any time.



    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.



    The Subordinate Voting Shares have been approved for listing on The Nasdaq
National Market under the symbol "TSIX", subject to official notice of issuance.
The Toronto Stock Exchange has conditionally approved the listing of the
Subordinate Voting Shares under the symbol "TSX". Listing is subject to us
fulfilling all of the requirements of The Toronto Stock Exchange on or before
July 11, 2000, including the distribution of the Subordinate Voting Shares to a
minimum number of public shareholders.


    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 $3 million.


    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,

                                      108
<PAGE>
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."

    In addition, in connection with our $565 million 360ATLANTIC credit
facility, affiliates of each of Goldman, Sachs & Co., Donaldson, Lufkin &
Jenrette Securities Corporation and Credit Suisse First Boston Corporation are
acting as lead arrangers and affiliates of each of TD Securities Inc. and BMO
Nesbitt Burns Inc. are acting as managing agents, for which they expect to
receive customary fees and expense reimbursements.

    In addition, in connection with the GlobeNet acquisition, affiliates of each
of TD Securities Inc. and Credit Suisse First Boston Corporation, shareholders
of GlobeNet, will purchase our Subordinate Voting Shares concurrently with this
offering and at the initial public offering price. TD Securities is also acting
as GlobeNet's financial advisor in connection with the GlobeNet acquisition and
will receive customary compensation for those services.

    An affiliate of Morgan Stanley & Co. Incorporated is currently providing
financial valuation services to one of our subsidiaries, for which it will
receive customary fees.

    Each of Donaldson, Lufkin & Jenrette Securities Corporation, Goldman, Sachs
& Co., Bear, Stearns & Co. Inc., Chase Securities Inc., Credit Suisse First
Boston Corporation, Morgan Stanley & Co. Incorporated, Salomon Smith Barney
Inc., RBC Dominion Securities Corporation and TD Securities (USA) Inc. is acting
as an initial purchaser in connection with the concurrent debt offerings.


    Affiliates of Donaldson, Lufkin & Jenrette Securities Corporation and Chase
Securities Inc. have made a commitment to provide up to $1.0 billion to us under
a credit facility. Those affiliates will receive customary financing fees in
connection with such facility.


    Gene Sykes, a director of ours, is a Managing Director of Goldman, Sachs &
Co., and Andrew Rush, a director of ours, is a Managing Director of DLJ Merchant

          ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS


    We are a corporation organized under the laws of Nova Scotia, Canada. 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.

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 $28,849,000 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
$3,584,000 for 1999 and Federal Large Corporation taxes of $2,690,000 for 1999
resulting from the proforma adjustments in notes 4 and 5.


    (VI) 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. (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.

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

    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.

            (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.

            (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.

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:

("Agreement") with Ledcor, Mi-Tech and Michels Pipeline Construction, Inc.
("Michels") (an affiliate of Mi-Tech). Pursuant to this agreement, Mi-Tech will

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

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.

    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.

                                                                ====
</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

                                AUDITORS' REPORT

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
in the United States.

                  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.

             LEDCOR INDUSTRIES LIMITED--TELECOMMUNICATIONS DIVISION

            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.

                       (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.

8.  INTERDIVISIONAL ACCOUNT

    This account comprises the balance due to other divisions in connection with
working capital advances. The balance due has no repayment terms and interest is
allocated, from LIL, on the basis as described in Note 3.

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
    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:

<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.

TO THE DIRECTORS AND SHAREHOLDERS OF
GLOBENET COMMUNICATIONS GROUP LIMITED

    We have audited the accompanying consolidated balance sheets of GlobeNet
Communications Group Limited as of December 31, 1999 and 1998 and the related
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 auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of GlobeNet
Communications Group Limited at December 31, 1999 and 1998 and the results of
its operations and its cash flows for the years ended December 31, 1999, 1998

                   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
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

             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)
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:

Computer equipment...................................  straight-line        3 years
Furniture and office equipment.......................  diminishing balance  20% per year
Software.............................................  straight-line        5 years
</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.

       (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

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.

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

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.

                      46,275,000 SUBORDINATE VOTING SHARES

    This offering of 46,275,000 Subordinate Voting Shares (the "Subordinate
Voting Shares") of 360NETWORKS INC. (the "Company" or "360NETWORKS") consists of
a new issue by the Company of 44,625,000 Subordinate Voting Shares and a
secondary offering of 1,650,000 Subordinate Voting Shares being sold by the
selling shareholder named in the U.S. Prospectus referred to below. The Company
will not receive any of the proceeds of the sale of Subordinate Voting Shares by
the selling shareholder.

    This prospectus incorporates the prospectus (the "U.S. Prospectus") included
in a Registration Statement on Form F-1 filed with the United States Securities
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 Toronto Stock Exchange has conditionally approved the listing of
the Subordinate Voting Shares under the symbol "TSX". Listing is subject to the
Company fulfilling all of the requirements of The Toronto Stock Exchange on or
before July 11, 2000, including the distribution of the Subordinate Voting
Shares to a minimum number of public shareholders. The Subordinate Voting Shares
have been approved for listing on the Nasdaq National Market under the symbol
"TSIX", subject to official notice of issuance. The offering price of each
Subordinate Voting Share, after giving effect to this offering, and other
material transactions but before exercise of the Underwriters' over-allotment
option, exceeds the Company's consolidated net tangible book value as of
December 31, 1999 by U.S.$11.63, resulting in a dilution of 89%. 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 was continued as a
company under the COMPANIES ACT (Nova Scotia) on April 17, 2000. Immediately
prior to the closing of the offering, the memorandum and articles of association
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
March 31, 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 $548 million;

    - the acquisition of all outstanding stock of GlobeNet;

    - the issuance of $700 million of senior notes in the concurrent debt

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

    - the completion of the $565 million 360ATLANTIC credit facility, of which

ELIGIBILITY FOR INVESTMENT

    In the opinion of Farris, Vaughan, Wills & Murphy, Canadian counsel to the

the meaning of the INCOME TAX ACT (Canada) and the regulations thereunder (the
"Act"), will be qualified investments under the Act for trusts governed by
registered retirement savings plans, registered retirement income funds,
deferred profit sharing plans and registered education savings plans. For these
purposes, each of the Nasdaq National Market and The Toronto Stock Exchange is a
prescribed stock exchange. Based on a certificate from the Company as to certain
factual matters, in the opinion of such counsel, the Subordinate Voting Shares,
if issued on the date hereof, would not, on the date hereof, be foreign property
for purposes of the Act.

    Eligibility of the Subordinate Voting Shares offered hereby for investment
by purchasers to whom any of the following statutes apply is, in certain cases,

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 authority of the Province of Ontario, the Company is exempt from
certain of the requirements of the laws of such jurisdiction relating to
continuous disclosure in its Annual Information Form and Management's Discussion
and Analysis filings. 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 Ontario, provided that
the relevant documents are filed with the securities regulatory authorities in
Ontario.

for Subordinate Voting Shares of the Company; (vii) the conversion or exchange
of Series A Non-Voting Preferred Shares into Subordinate Voting Shares; and

January 1, 1999: (i) the Company's acquisition of GlobeNet; (ii) the elimination
of minority interest earnings and the amortization of goodwill arising from the

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 Canada 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 information give effect to the acquisition
by the Company of GlobeNet in a transaction to be accounted for as a purchase
(the "Acquisition"). 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 as at December 31, 1999. The unaudited pro
forma 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.

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 $17,011,000.

    - 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.

    - The elimination of stock based compensation expense included in GlobeNet's
      Financial statements to conform to the Company's Canadian GAAP accounting
      policy whereby no stock based compensation is recorded on stock options
      granted.

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 $132,367,000 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.

IV) INCOME TAXES

    This adjustment records an income tax recovery of $17,121,000 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 $3,584,000 for 1999 and Federal Large Corporation taxes of $2,690,000 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).

                                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.

                           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

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

    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>

    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
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 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
interests of the Company's subsidiaries or enter into certain mergers and
consolidations.

8. REDEEMABLE CONVERTIBLE PREFERRED STOCK

    On September 9, 1999 the Company authorized various classes of preferred
shares.

    SERIES A NON-VOTING REDEEMABLE CONVERTIBLE PREFERRED SHARES

    On September 9, 1999, the Company issued 141,868,928 Series A Non-Voting
Convertible Preferred Shares ("Series A Preferred Shares") for $345,000,000. On
December 22, 1999, the Company issued an additional 9,082,384 Series A Preferred
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

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

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

    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.

    Tax losses arising in 1999 of $9,342,000 expire in 2006.

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

(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.

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,

                  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.

            NOTES TO THE DIVISIONAL FINANCIAL STATEMENTS (CONTINUED)

                       (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.

            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.

8. INTERDIVISIONAL ACCOUNT

    This account comprises the balance due to other divisions in connection with
working capital advances. The balance due has no repayment terms and interest is
allocated, from LIL, on the basis as described in Note 3.

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 option to withdraw from all leases in April, 1999 and therefore has no
       commitments beyond that date. Lease expenses were the following:

of the Division's total revenues/contract costs in one or more periods, as
follows:

    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

                   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
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:

</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.

       (IN THOUSANDS OF U.S. DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

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.

    ROCOM TBI LIMITED

    During 1998, the Company sold its interest in Rocom TBI Limited, a

using the equity method. Under the equity method, the Company reported 100% of

</TABLE>

    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.

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

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

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.

         respect to the transactions herein contemplated, the Selling
         Shareholder will deliver to you prior to or at the First Time of
         Delivery (as defined in Section 3(a)) a properly completed and executed
         United States Treasury Department Form W-9 (or other applicable form or

         thereof); and

                  (ix) The obligations of the Selling Shareholder hereunder
         shall not be terminated by operation of law whether, in the case of a

Company and the Selling Shareholder agree, severally and not jointly, to sell to
each of the Underwriters, and each of the Underwriters agrees, severally and not
jointly, to purchase from the Company and the Selling Shareholder, at a purchase
price per share of $.............., the number of Firm Shares (to be adjusted by
you so as to eliminate fractional shares) determined by multiplying the
aggregate number of Shares to be sold by the Company and the Selling Shareholder
as set forth opposite its name in Schedule E hereto by a fraction, the numerator
of which is the aggregate number of Firm Shares to be purchased by such
Underwriter as set forth opposite the name of such Underwriter in Schedule A
hereto and the denominator of which is the aggregate number of Firm Shares to be
purchased by all of the Underwriters from the Company and the Selling
Shareholder hereunder and (b) in the event and to the extent that the
Underwriters shall exercise the election to purchase Optional Shares as provided
below, the Company agrees to sell to each of the Underwriters, and each of the
Underwriters agrees, severally and not jointly, to purchase from the Company, at
the purchase price per share set forth in clause (a) of this Section 2, that
portion of the number of Optional Shares as to which such election shall have
been exercised (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying such number of Optional Shares by a fraction the
numerator of which is the maximum number of Optional Shares which such
Underwriter is entitled to purchase as set forth opposite the name of such
Underwriter in Schedule A hereto and the denominator of which is the maximum
number of Optional Shares that all of the Underwriters are entitled to purchase
hereunder.

         The Company, as and to the extent indicated in Schedule E hereto,
hereby grants, to the Underwriters the right to purchase at their election up to
6,941,250 Optional Shares, at the purchase price per share set forth in the
paragraph above, for the sole purpose of covering sales of shares in excess of
the number of Firm Shares. Any such election to purchase Optional Shares shall
be made in proportion to the maximum number of Optional Shares to be sold by the
Company as set forth in Schedule E hereto initially with respect to the Optional
Shares to be sold by the Company. Any such election to purchase Optional Shares
may be exercised only by written notice from you to the Company, given within a
period of 30 calendar days after the date of this Agreement and setting forth
the aggregate number of Optional Shares to be purchased and the date on which
such Optional Shares are to be delivered, as determined by you but in no event
earlier than the First Time of Delivery (as defined in Section 3(a)) or, unless
you and the Company otherwise agree in writing, earlier than two or later than
ten business days after the date of such notice.

by the Sub-Underwriters will be purchased by the Sub-Underwriters from their
respective Underwriter affiliates at the Time of Delivery (as defined in Section
3(a)) at a price equal to the purchase price set forth in Section 2 above or
such purchase price less an amount to be mutually agreed upon by the
Sub-Underwriter and its Underwriter affiliate, which amount shall not be greater
than the underwriting commission set forth on the cover page of the Prospectus
and the Canadian Prospectus.

                  (c) The Underwriters shall give prompt written notice to
the Company and the Selling Shareholder when, in the opinion of the
Underwriters, they have ceased distribution to the public of the Firm Shares
or the Optional Shares, as the case may be, and after the First Time of

proceeds realized in each of the provinces from such distribution.

         3.       (a) The Shares to be purchased by each Underwriter hereunder,
in definitive form, and in such authorized denominations and registered in such
names as Goldman, Sachs & Co. and DLJ may request upon at least forty-eight

delivered by or on behalf of the Company and the Selling Shareholder to Goldman,
Sachs & Co. and DLJ, through the facilities of the Depository Trust Company

such Underwriter of the purchase price therefor by wire transfer of Federal
(same-day) funds to the account specified by the Company and the Selling
Shareholder, as their interests may appear, to Goldman, Sachs & Co. and DLJ at
least forty-eight hours in advance. The Company will cause the certificates
representing the Shares to be made available for checking and packaging at least
twenty-four hours prior to the Time of Delivery (as defined below) with respect
thereto at the office of DTC or its designated custodian (the "DESIGNATED
OFFICE"). The time and date of such delivery and payment shall be, with respect

in the written notice given by Goldman, Sachs & Co. and DLJ of the Underwriters'
election to purchase such Optional Shares, or such other time and date as
Goldman, Sachs & Co., DLJ and the Company may agree upon in writing. Such time
and date for delivery of the Firm Shares is herein called the "FIRST TIME OF
DELIVERY", such time and date for delivery of the Optional Shares, if not the
First Time of Delivery, is herein called the "SECOND TIME OF DELIVERY", and each
such time and date for delivery is herein called a "TIME OF DELIVERY".

                  (b) The documents to be delivered at each Time of Delivery
by or on behalf of the parties hereto pursuant to Section 6 hereof, including
the cross receipt for the Shares, will be delivered at the offices of Latham

Closing Location on the New York Business Day next preceding such Time of
Delivery, at which meeting the final drafts of the documents to be delivered
pursuant to the preceding sentence will be available for review by the parties

the expiration of nine months after the time of issue of the Prospectus in
connection with the offering or sale of the Shares and if at such time any
events shall have occurred as a result of which the Prospectus or the Canadian
Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were

supplement the Prospectus or the Canadian Prospectus in order to comply with the
Act, to notify you and upon your request to prepare and furnish without charge

         described in the Prospectus and the Canadian Prospectus) including the
         execution, delivery and performance of the Canadian Telecommunications
         Agreements by the parties thereto will not violate or conflict with any
         provisions of the Telecommunications Act or the Ownership Regulations,
         any applicable rule, regulation, judgment, order or decree of the
         Canadian Radio-television and Telecommunications Commission (the
         "CRTC") or Industry Canada or the articles or by-laws, or the
         Memorandum of Association or Articles of Association, as the case may
         be, of each of the parties thereto;

                      (xix) no filing, license, consent, permission, approval,
         authorization, or order of any court or governmental agency or body in
         Canada is required to be obtained by the Canadian Companies under the
         laws of the Provinces of British Columbia or Nova Scotia or the federal
         laws of Canada applicable therein, in connection with the execution,
         delivery and performance of this Agreement by the Company or to permit
         the issue, delivery and sale by the Company of the Shares, except such
         filings, licenses, consents, permissions, approvals, authorizations or
         orders that have been obtained;

                      (xx) No filing, license, consent, permission, approval,
         authorization, or order of any court or governmental agency of body in
         Canada is required to be obtained by any of the Canadian Companies from
         the CRTC or Industry Canada in connection with the Canadian
         Telecommunications Arrangement;

                      (xxi) the choice of law provisions set forth in Section 16
         hereof, is legal, valid and binding under the laws of the Province of
         British Columbia and the federal laws of Canada applicable therein,
         provided that such choice of law is bona fide (in the sense that it was
         not made with a view to avoiding the consequences of the laws of any
         other jurisdiction) and provided that such choice of law is not
         contrary to public policy, as that term is applied by the courts in the




                                       25
<PAGE>

         Province of British Columbia ("PUBLIC POLICY"); such counsel knows of
         no Public Policy reason why the courts in the Province of British
         Columbia (a "CANADIAN COURT") would not give effect to the choice of
         New York law as the proper law of this Agreement and if this Agreement
         is sought to be enforced in the Province of British Columbia in
         accordance with the laws applicable thereto as chosen by the parties,
         namely New York law, a Canadian Court would, subject to the foregoing,
         recognize the choice of New York law, and, upon appropriate evidence as
         to such law being adduced, apply such law; provided that none of the
         provisions of this Agreement, or of applicable New York law, are
         contrary to Public Policy or foreign revenue, expropriation or penal
         laws; provided, however, that, in matters of procedure, the laws of the
         Province of British Columbia will be applied and a Canadian Court will
         retain discretion to decline to hear such action if it is contrary to
         Public Policy for it to do so, or if it is not the proper forum to hear
         such an action, or if concurrent proceedings are being brought
         elsewhere;

                      (xxii) there are no reasons, to such counsel's knowledge,
         under the laws of the Province of British Columbia or the federal laws
         of Canada applicable therein or with respect to the application of New
         York law by a Canadian Court, why enforcement of this Agreement would
         be avoided on the grounds of Public Policy;

                      (xxiii) the Company has the legal capacity to sue and be
         sued in its own name under the laws of the Province of British Columbia
         and the federal laws of Canada applicable therein; the Company has the
         power to submit, and has irrevocably submitted, to the non-exclusive
         jurisdiction of the federal or state courts located in the Borough of
         Manhattan in The City of New York (a "NEW YORK COURT") and has validly
         and irrevocably appointed CT Corporation System as its authorized agent
         for the purpose described in Section 16 hereof; the Company has the
         power to submit, and has irrevocably submitted, to the non-exclusive
         jurisdiction of the New York Court and has validly and irrevocably
         appointed CT Corporation System as its authorized agent under the laws
         of the Province of British Columbia and the federal laws of Canada
         applicable therein; the irrevocable submission of the Company to the
         non-exclusive jurisdiction of the New York Court and the waivers by it
         of any immunity and any objection to the venue of the proceeding in a
         New York Court herein is legal, valid and binding under the laws of the
         Province of British Columbia and the federal laws of Canada applicable
         therein, and such counsel knows of no reason why a Canadian Court would
         not give effect to such submission and waivers; the irrevocable
         submission of the Company to the non-exclusive jurisdiction of the New
         York Court and the waivers by the Company of any immunity and any
         objection to the venue of the proceeding in a New York Court herein is
         legal, valid and binding under the laws of the Province of British
         Columbia and the federal laws of Canada applicable therein, and such
         counsel knows of no reason why a Canadian Court would not give effect
         to such submission and waivers;

                      (xxiv) service of process in the manner set forth in
         Section 16 hereof will be effective to confer valid personal
         jurisdiction over the Company under the laws of the Province of British
         Columbia and the federal laws of Canada applicable therein;

                      (xxv) a Canadian Court will recognize as valid and final,
         and will enforce, any final and conclusive judgment in personam, of any
         New York Court that is not impeachable as void or voidable under the
         internal laws of the State of New York for a sum certain in respect of
         the enforcement of the obligations of the Company under this Agreement,
         if (i) the court rendering such judgment had jurisdiction over the
         judgment debtor, as recognized by the Canadian Court (and submission by
         the Company in this Agreement to the jurisdiction of the New York
         Court, will be sufficient for this purpose), (ii) such judgment was not
         obtained by fraud or in a manner contrary to natural justice



                                       26
<PAGE>

         and the enforcement thereof would not be inconsistent with Public
         Policy, or contrary to any order made by the Attorney General of Canada
         under the Foreign Extraterritorial Measures Act (Canada), (iii) the
         enforcement of such judgment does not constitute, directly or
         indirectly, the enforcement of foreign revenue, expropriatory or penal
         laws, (iv) the action to enforce such judgment is commenced within the
         applicable limitation period and (v) such counsel knows of no Public
         Policy reason for avoiding the recognition of judgments of a New York
         Court under this Agreement under the laws of the Province of British
         Columbia and the federal laws of Canada applicable therein;

                      (xxvi) all necessary documents have been filed, all
         requisite proceedings have been taken and all legal requirements have
         been fulfilled by the Company in order to qualify the Shares for
         distribution and sale to the public in each of the Canadian
         Jurisdictions by or through persons appropriately registered under the
         Canadian Securities Laws who have complied with all relevant provisions
         of such laws;

                      (xxvii) Except for withholding tax eligible on any amount
         paid or credited, or deemed to be paid or credited to a non-resident
         person as, on account or in lieu of payment of, or in satisfaction of a
         dividend, no stamp duty, registration or documentary taxes, duties or
         similar charges are payable to the Canadian government or to any
         political subdivision or taxing authority thereof or therein in
         connection with (A) the issuance, sale and delivery by the Company and
         the Selling Shareholder to or for the respective accounts of the
         Underwriters of the Shares or (B) the sale and delivery outside Canada
         by the Underwriters of the Shares to the initial purchasers thereof in
         the manner contemplated in this Agreement, no withholding tax will be
         payable by or on behalf of the Underwriters to the Canadian government
         or to any political subdivision or taxing authority thereof or therein
         in connection with (A) the issuance, sale and delivery by the Company
         and the Selling Shareholder to or for the respective accounts of the
         Underwriters of the Shares, (B) the sale and delivery outside Canada by
         the Underwriters of the Shares to the initial purchasers thereof in the
         manner contemplated in this Agreement; or (C) the payment or crediting
         by the Company or the Selling Shareholder of any commission or fee to
         or for the respective account of any Underwriter who is not resident in
         Canada, provided that commission or fee is payable in respect of
         services rendered by such Underwriter outside of Canada.

                      (xxviii) No goods and services tax imposed under the
         federal laws of Canada will be collectible by an Underwriter in respect
         of the payment or crediting of any discount, commission or fee as
         contemplated by this Agreement to any Underwriters, provided that any
         such discount, commission or fee is payable in respect of services
         performed by such Underwriter wholly outside of Canada;

                      (xxix) (a) Urbanlink is eligible to operate as a
         telecommunications common carrier in Canada, as defined under and in
         accordance with the Telecommunications Act (Canada) (the
         "Telecommunications Act") and the Canadian Telecommunications Common
         Carrier Ownership and Control Regulations (the "OWNERSHIP
         Regulations"); (b) none of the Canadian Companies violates the

         against operating in Canada as a telecommunications common carrier when
         ineligible to do so; (c) control of Urbanlink is not exercised by any
         person(s) that is (are) not Canadian, in accordance with the meanings
         ascribed to the term "control" under the Telecommunications Act and the

         Canadian Companies

         is in violation of any judgment, decree, order, writ, law, statute,

         Telecommunications Act, applicable to any of the Canadian Companies, or
         any interpretation or policy relating thereto known to such counsel to
         be applicable to them;

                      (xxx) after giving effect to the performance by the
         Company of its obligations under this Agreement at such Time of
         Delivery:

                            (a) not less than eighty percent of the members of

         and delivered by or on behalf of the Selling Shareholder; and the
         sale of the Shares to be sold by the Selling Shareholder hereunder
         and the compliance by the Selling Shareholder with all of the
         provisions of this Agreement, and the consummation of the
         transactions herein and therein contemplated will not conflict with
         or result in a breach or violation of any agreement which the
         Selling Shareholder has represented to such counsel as material to
         the Selling Shareholder, all of which are listed on a schedule to

                      (iii) No consent, approval, authorization or order of any
         court or governmental agency or body is required for the consummation

         under the laws of the Province of Alberta, or the federal laws of
         Canada applicable therein or with respect to the application of New
         York law by a Canadian Court, why enforcement of this Agreement would
         be avoided on the grounds of Public Policy.

a certificate of the Selling Shareholder in respect of matters of fact as to
ownership of the Shares sold by the Selling Shareholder, provided that such
counsel shall state that they believe that both you and they are justified in
relying upon such certificate;

                      (e) On the date of the Prospectus and the Canadian
Prospectus at a time prior to the execution of this Agreement, at 9:30 a.m., New
York City time, on the effective date of any post-effective amendment to the
Registration Statement filed subsequent to the date of this Agreement and also
at each Time of Delivery, PricewaterhouseCoopers LLP and Deloitte & Touche LLP
shall have furnished to you a letter or letters, dated the respective dates of
delivery thereof, in form and substance satisfactory to you, containing the
information and statements of the type ordinarily included in accountants'
"comfort letters" to underwriters with respect to the financial statements and
certain financial information contained in the Registration Statement,
Prospectus and Canadian Prospectus;

                      (f) (i) Neither the Company nor any of its subsidiaries
shall have sustained since the date of the latest audited financial statements
included in the Prospectus and the Canadian Prospectus any loss or interference
with its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree, otherwise than as set forth or contemplated in the Prospectus
and the Canadian Prospectus, and (ii) since the respective dates as of which
information is given in the Prospectus and the Canadian Prospectus there shall
not have been any change in the capital stock or long-term debt of the Company
or any of its subsidiaries or any change, or any development involving a
prospective change, in or affecting the general affairs, management, financial
position, shareholders' equity or results of operations of the



                                       31
<PAGE>

Company and its subsidiaries, otherwise than as set forth or contemplated in the
Prospectus and the Canadian Prospectus, the effect of which, in any such case
described in clause (i) or (ii), is in the judgment of the Representatives so
material and adverse as to make it impracticable or inadvisable to proceed with
the public offering or the delivery of the Shares being delivered at such Time
of Delivery on the terms and in the manner contemplated in the Prospectus and
the Canadian Prospectus;

                      (g) On or after the date hereof (i) no downgrading shall
have occurred in the rating accorded the Company's debt securities by any
"nationally recognized statistical rating organization", as that term is defined
by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities;

                      (h) On or after the date hereof there shall not have
occurred any of the following: (i) the suspension or material limitation of
trading in securities or other instruments on the New York Stock Exchange, The
Toronto Stock Exchange, the American Stock Exchange or the Nasdaq National
Market or limitation on prices for securities or other instruments on any such
exchange or the Nasdaq National Market, (ii) the suspension or material
limitation of trading of any securities of the Company on any exchange or in the
over-the-counter market, (iii) the declaration of a banking moratorium by either
federal or New York State authorities or authorities in Canada or any province
thereof, (iv) a change or development involving a prospective change in taxation
affecting the Company, the Shares or the transfer thereof or the imposition of
exchange controls by the United States or Canada, (v) the outbreak or escalation
of hostilities involving the United States or Canada or the declaration by the
United States or Canada of a national emergency or war, if the effect of any
such event specified in this clause (v) in the judgment of the Representatives
makes it impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered at such Time of Delivery on the terms and
in the manner contemplated in the Prospectus, (vi) the occurrence of any
material adverse change in the existing financial, political or economic
conditions in the United States or Canada or elsewhere which, in the judgment of
the Representatives would materially and adversely affect the financial markets
or the market for the Shares and other equity securities, (vii) the enactment,
publication, decree or other promulgation of any federal, state, provincial or
municipal statute, regulation, rule or order of any court or other governmental
authority which in the judgment of the Representatives materially and adversely
affects, or will materially and adversely affect, the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, or (viii) the taking of any action by any
federal, state, provincial, municipal or local government or agency in respect
of its monetary or fiscal affairs which in the judgment of the Representatives
has a material adverse effect on the financial markets in the United States or
Canada.

                      (i) The Shares at such Time of Delivery shall have been
conditionally approved for listing on the Exchange, subject to the Company
fulfilling all of the requirements of the Exchange, and shall be listed for
quotation on NASDAQ;

                      (j) the Canadian Telecommunications Arrangement shall have
been established and the Canadian Telecommunications Agreements shall have been
executed and delivered by each of the parties thereto;



                                       32
<PAGE>

                      (k) The Company has obtained and delivered to the
Underwriters executed copies of an agreement from each of the parties listed on
Schedule G hereto agreeing not to sell, transfer of hypothecate their Shares for
a set period of time in form and substance satisfactory to you;

                      (l) The Company shall have complied with the provisions of
Section 4(c) hereof with respect to the furnishing of prospectuses on the New
York Business Day next succeeding the date of this Agreement;

                      (m) PricewaterhouseCoopers LLP shall have furnished to the
Underwriters an opinion, dated the respective dates of the documents enumerated
below, in form and substance satisfactory to the Underwriters that the French
language versions of the pro forma financial statements and notes to such
statements, the historical financial statements and notes to such statements and
the related auditors' reports on such statements, the Management's Discussion
and Analysis of Financial Condition and Results of Operations and the tables of
financial and accounting information and notes thereto (collectively, the
"Financial Information") contained in each of the Canadian Preliminary
Prospectus, the Amended Canadian Preliminary Prospectus, the Canadian Final
Prospectus and the Canadian Prospectus are in all material respects a complete
and proper translation of the English language versions thereof.

                      (n) Lafleur, Brown, Quebec counsel to the Company, shall
have furnished to the Underwriters an opinion, in form and substance
satisfactory to the Underwriters, dated the respective dates of the documents
enumerated below, that, except for the Financial Information as to which they
need express no opinion, the French language version of each of the Canadian
Preliminary Prospectus, the Amended Canadian Preliminary Prospectus, the
Canadian Final Prospectus and the Canadian Prospectus is in all material
respects a complete and proper translation of the English language version
thereof and that such version is not susceptible of any materially different
interpretation with respect to any matter contained therein; and that all laws
relating to the use of the French language will have been complied with in
connection with the offer and sale of the Shares in the Province of Quebec.

                      (o) On or prior to such Time of Delivery, the Transfer
Restriction Agreement, in form and substance satisfactory to the Underwriters
and their counsel, shall have been executed and delivered to you by the parties
thereto.

                      (p) The Company and the Selling Shareholder shall have
furnished or caused to be furnished to you at such Time of Delivery certificates
of officers of the Company and of the Selling Shareholder, respectively,
satisfactory to you as to the accuracy of the representations and warranties of
the Company and the Selling Shareholder, respectively, herein at and as of such
Time of Delivery, as to the performance by the Company and the Selling
Shareholder of all of their respective obligations hereunder to be performed at
or prior to such Time of Delivery, and as to such other matters as you may
reasonably request, and the Company shall have furnished or caused to be
furnished certificates as to the matters set forth in subsections (a) and (f) of
this Section.

         7.  (a) The Company and the Selling Shareholder, jointly and severally,
will indemnify and hold harmless each Underwriter and Sub-Underwriter against
any losses, claims, damages or liabilities, joint or several, to which such
Underwriter and Sub-Underwriter may become subject, under the Act, the Canadian
Securities Laws or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based



                                       33
<PAGE>

upon (i) an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, 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
or (ii) any misrepresentation or alleged misrepresentation (as defined in the
Canadian Securities Laws) contained in the Canadian Preliminary Prospectus, the
Amended Canadian Preliminary Prospectus, the Canadian Final Prospectus, the
Canadian Prospectus, any Canadian Prospectus Amendment, or any untrue, false or
misleading statement therein, or any omission or alleged omission to state
therein any material fact or information required to be stated therein or
necessary to make any of the statements therein not misleading in light of the
circumstances in which they were made, and will reimburse each Underwriter and
Sub-Underwriter for any legal or other expenses reasonably incurred by such
Underwriter and Sub-Underwriter in connection with investigating or defending
any such action or claim as such expenses are incurred; PROVIDED, HOWEVER, that
the Company and the Selling Shareholder shall not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement,
the Prospectus or any such amendment or supplement, the Canadian Preliminary
Prospectus, the Amended Canadian Preliminary Prospectus, the Canadian Final
Prospectus, the Canadian Prospectus or any Canadian Prospectus Amendment, in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Goldman, Sachs & Co. or DLJ expressly for use
therein; PROVIDED, FURTHER, that the Selling Shareholder will not be liable for
any amounts pursuant to this Section 7(a) in excess of the total proceeds to the
Selling Shareholder from the sale of the Shares.

             (b) Each Underwriter and Sub-Underwriter will indemnify and hold
harmless the Company and the Selling Shareholder against any losses, claims,
damages or liabilities to which the Company or the Selling Shareholder may
become subject, under the Act, the Canadian Securities Laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, the Canadian Preliminary Prospectus, the Amended Canadian Preliminary
Prospectus, the Canadian Final Prospectus, the Canadian Prospectus or any
Canadian Prospectus Amendment 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 made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement, the Canadian Preliminary Prospectus, the Amended Canadian
Preliminary Prospectus, the Canadian Final Prospectus, the Canadian Prospectus
or any Canadian Prospectus Amendment in reliance upon and in conformity with
written information furnished to the Company by such Underwriter or
Sub-Underwriter through Goldman, Sachs & Co. or DLJ expressly for use therein;
and will reimburse the Company and the Selling Shareholder for any legal or
other expenses reasonably incurred by the Company or the Selling Shareholder in
connection with investigating or defending any such action or claim as such
expenses are incurred.

             (c) Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the



                                       34
<PAGE>

indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party otherwise than under such subsection. In
case any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party. No
Indemnifying Party shall be required to indemnify an Indemnified Party for any
amount paid or payable by such Indemnified Party in the settlement of any
action, proceeding or investigation without the written consent of such
Indemnifying Party, with consent which shall not be unreasonably withheld.

         (d) If the indemnification provided for in this Section 7 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Shareholder on the one
hand and the Underwriters and Sub-Underwriters on the other from the offering of
the Shares. If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law or if the indemnified party failed
to give the notice required under subsection (c) above, then each indemnifying
party shall contribute to such amount paid or payable by such indemnified party
in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of the Company and the Selling Shareholder on the
one hand and the Underwriters and Sub-Underwriters on the other in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Selling Shareholder on the one hand and the Underwriters and the
Sub-Underwriters on the other shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Company and the Selling Shareholder bear to the total underwriting discounts
and commissions received by the Underwriters and the Sub-Underwriters, in each
case as set forth in the table on the cover page of the Prospectus and the
Canadian Prospectus. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Selling Shareholder on the one hand
or the Underwriters and Sub-Underwriters on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent




                                       35
<PAGE>

such statement or omission. The Company, the Selling Shareholder and the
Underwriters and Sub-Underwriters agree that it would not be just and equitable
if contributions pursuant to this subsection (d) were determined by PRO RATA
allocation (even if the Underwriters and Sub-Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (d). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), no Underwriter or Sub-Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
or Sub-Underwriter has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' and Sub-Underwriters'
obligations in this subsection (d) to contribute are several in proportion to
their respective underwriting obligations and not joint.

             (e) The obligations of the Company and the Selling Shareholder
under this Section 7 shall be in addition to any liability which the Company and
the Selling Shareholder may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls any Underwriter or
Sub-Underwriter within the meaning of the Act; and the obligations of the
Underwriters and Sub-Underwriters under this Section 7 shall be in addition to
any liability which the respective Underwriters and Sub-Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company (including any person who, with his or her
consent, is named in the Registration Statement as about to become a director of
the Company) and to each person, if any, who controls the Company or the Selling
Shareholder within the meaning of the Act.

         8. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Shareholder shall be entitled to a
further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company and
the Selling Shareholder that you have so arranged for the purchase of such
Shares, or the Company and the Selling Shareholder notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling
Shareholder shall have the right to postpone a Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement, the Prospectus or the Canadian
Prospectus, or in any other documents or arrangements, and the Company agrees to
file promptly any amendments to the Registration Statement, the Prospectus or
the Canadian Prospectus which in your opinion may thereby be made necessary. The
term "Underwriter" as used in this Agreement shall include any person
substituted under this Section with like effect as if such person had originally
been a party to this Agreement with respect to such Shares.



                                       36
<PAGE>

             (b) If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company
and the Selling Shareholder as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,
then the Company and the Selling Shareholder shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

             (c) If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company
and the Selling Shareholder as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Shareholder shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Company to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Shareholder, except for the expenses
to be borne by the Company and the Selling Shareholder and the Underwriters as
provided in Section 5 hereof and the indemnity and contribution agreements in
Section 7 hereof; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

         9. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Shareholder and the several
Underwriters and Sub-Underwriters, as set forth in this Agreement or made by or
on behalf of them, respectively, pursuant to this Agreement, shall remain in
full force and effect, regardless of any investigation (or any statement as to
the results thereof) made by or on behalf of any Underwriter or Sub-Underwriter
or any controlling person of any Underwriter or Sub-Underwriter, or the Company,
or the Selling Shareholder, or any officer or director or controlling person of
the Company, or any controlling person of the Selling Shareholder, and shall
survive delivery of and payment for the Shares.

         Anything herein to the contrary notwithstanding, the indemnity
agreement of the Company in subsection (a) of Section 7 hereof, the
representations and warranties in subsections (a)(ii) and (a)(iii) of Section 1
hereof and any representation or warranty as to the accuracy of the Registration
Statement or the Prospectus contained in any certificate furnished by the
Company pursuant to Section 6 hereof, insofar as they may constitute a basis for
indemnification for liabilities (other than payment by the Company of expenses
incurred or paid in the successful defense of any action, suit or proceeding)
arising under the Act, shall not extend to the extent of any interest therein of
a controlling person or partner of an Underwriter or Sub-Underwriter who is a
director, officer or controlling person of the Company when the Registration
Statement has become effective or who, with his or her consent, is named in the
Registration Statement as about to become a director of the Company, except in
each case to the extent that an interest of such character shall have been
determined by a court of appropriate jurisdiction as not against public policy
as expressed in the Act. Unless in the opinion of counsel for the Company the
matter has been settled by controlling precedent, the



                                       37
<PAGE>

Company will, if a claim for such indemnification is asserted, submit to a court
of appropriate jurisdiction the question of whether such interest is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         10. If this Agreement shall be terminated pursuant to Section 8 hereof,
neither the Company nor the Selling Shareholder shall then be under any
liability to any Underwriter or Sub-Underwriter except as provided in Sections 5
and 7 hereof; but, if for any other reason any Shares are not delivered by or on
behalf of the Company and the Selling Shareholder as provided herein, the
Company and the Selling Shareholder pro rata (based on the number of Shares to
be sold by the Company and Selling Shareholder hereunder) will reimburse the
Underwriters and Sub-Underwriters through you for all out-of-pocket expenses
approved in writing by you, including fees and disbursements of counsel,
reasonably incurred by the Underwriters and Sub-Underwriters in making
preparations for the purchase, sale and delivery of the Shares not so delivered,
but the Company and the Selling Shareholder shall then be under no further
liability to any Underwriter or Sub-Underwriter in respect of the Shares not so
delivered except as provided in Sections 5 and 7 hereof.

         11. In all dealings hereunder, you shall act on behalf of each of the
Underwriters and Sub-Underwriters, and the parties hereto shall be entitled to
act and rely upon any statement, request, notice or agreement on behalf of any
Underwriter or Sub-Underwriter made or given by you jointly or by Goldman, Sachs
& Co. and DLJ on behalf of you as the representatives.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters or the Sub-Underwriters shall be delivered
or sent by mail, telex or facsimile transmission to you as the representatives
in care of Goldman, Sachs & Co., 32 Old Slip, 21st Floor, New York, New York
10005, Attention: Registration Department; if to the Selling Shareholder shall
be delivered or sent by mail, telex or facsimile transmission to counsel for the
Selling Shareholder at its address set forth in Schedule E hereto; and if to the
Company shall be delivered or sent by mail, telex or facsimile transmission to
the address of the Company set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter or its
Sub-Underwriter affiliate pursuant to Section 7(c) hereof shall be delivered or
sent by mail, telex or facsimile transmission to such Underwriter or its
Sub-Underwriter affiliate at its address set forth in its Underwriters'
Questionnaire or telex constituting such Questionnaire, which address will be
supplied to the Company or the Selling Shareholder by you on request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

         12. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Sub-Underwriters, the Company and the Selling
Shareholder and, to the extent provided in Sections 7 and 9 hereof, the officers
and directors of the Company and each person who controls the Company, the
Selling Shareholder or any Underwriter or Sub-Underwriter, and their respective
heirs, executors, administrators, successors and assigns, and no other person
shall acquire or have any right under or by virtue of this Agreement. No
purchaser of any of the Shares from any Underwriter or Sub-Underwriter shall be
deemed a successor or assign by reason merely of such purchase.

         13. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.



                                       38

         14. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK.

         15. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         16. The Company and its subsidiaries agree that any suit, action or
proceeding against them brought by any Underwriter or Sub-Underwriter, the
directors, officers, employees and agents of any Underwriter, or by any person
who controls any Underwriter or Sub-Underwriter, arising out of or based upon
this Agreement or the transactions contemplated hereby, may be instituted in any
State or Federal court in The City of New York, and waive any objection which
they may now or hereafter have to the laying of venue of any such proceeding,
and irrevocably submit to the non-exclusive jurisdiction of such courts in any
suit, action or proceeding. Each of the Company and the Selling Shareholder has
appointed CT Corporation System as its authorized agent (the "AUTHORIZED AGENT")
upon whom process may be served in any suit, action or proceeding arising out of
or based upon this Agreement or the transactions contemplated herein that may be
instituted in any State or Federal court in The City of New York, by any
Underwriter or Sub-Underwriter, the directors, officers, employees and agents of
any Underwriter or Sub-Underwriter, or by any person, if any, who controls any
Underwriter or Sub-Underwriter, and expressly accept the non-exclusive
jurisdiction of any such court in respect of any such suit, action or
proceeding. Each of the Company and the Selling Shareholder hereby represents
and warrants that the Authorized Agent has accepted such appointment and has
agreed to act as said agent for service of process, and each of the Company and
the Selling Shareholder agrees to take any and all action, including the filing
of any and all documents that may be necessary to continue such appointment in
full force and effect as aforesaid. Service of process upon the Authorized Agent
shall be deemed, in every respect, effective service of process upon the Company
or the Selling Shareholder, as the case may be. Notwithstanding the foregoing,
any action arising out of or based upon this Agreement may be instituted by any
Underwriter or Sub-Underwriter, the directors, officers, employees and agents of
any Underwriter or Sub-Underwriter, or by any person who controls any
Underwriter or Sub-Underwriter, in any court of competent jurisdiction in
Canada.

         If the foregoing is in accordance with your understanding, please sign
and return to us one for the Company and each of the Representatives plus one
for each counsel, if any counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Underwriters and the Sub-Underwriters, this letter
and such acceptance hereof shall constitute a binding agreement among each of

Conversion Date to deposit the certificate or certificates representing Class A
Non-Voting Shares into trust for holders of the Class B Subordinate Voting

notice of conversion or in a subsequent notice to the registered holders of the
Class B Subordinate Voting Shares in respect of which the deposit was made. Upon

on the basis of the total number of shares of Class B Subordinate Voting Shares
the holder is at the time converting into Series A Non-Voting Preferred Shares
and the number of Series A Non-Voting Preferred Shares issuable upon such
aggregate conversion.

                  The holders of Series A Non-Voting Preferred Shares shall be

declared, paid, issued or distributed with respect to shares of Common Shares
into which such share of Series A Non-Voting Preferred Shares could be converted
pursuant to the provisions of Section 1.6 of this Article C, on the record date
for the determination of holders of Common Shares entitled to such dividends.
The Board of Directors may not declare, and the Company shall not pay, issue or
distribute, any dividend on any Common Shares unless simultaneously the Board of
Directors declares, and the Company pays, issues or distributes the dividend on
the Series A Non-Voting Preferred Shares specified in the first sentence of this
Section 1.2. The holders of Series A Non-Voting Preferred Shares shall not be
entitled to any dividend other than, or in excess of, the dividends as

1.4               RETIRED SHARES

                  Any Series A Non-Voting Preferred Shares converted, purchased

1.5               LIQUIDATION, DISSOLUTION OR WINDING UP

         (1)      Upon (i) any liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary, (ii) a sale of all or substantially
all of the assets of the Company or (iii) a reorganization of the Company
required by any court or administrative body in order to comply with any
provision of law (each of the events referred to in clauses (i), (ii) and (iii)
being referred to as a "Liquidation"), the holders of Series A Non-Voting
Preferred Shares shall be entitled to receive and to be paid out of assets of
the Company available for distribution to its shareholders, before any payment
or distribution shall be made on any Junior Shares, the greater of (i) the
Series A Non-Voting Liquidation Value with respect to each such outstanding
Series A Non-Voting Preferred Share, and (ii) the amount which would have been
paid in such Liquidation, based upon the number of Class A Non-Voting Shares
into which a Series A Non-Voting Preferred Share could be converted pursuant to
the provisions of Section 1.6 of this Article C. If, upon any Liquidation of the
Company, the assets of the Company available for distribution shall be
insufficient to pay in full the Series A Non-Voting Liquidation Value with
respect to each outstanding Series A Non-Voting Preferred Share, then such
assets shall be distributed among the holders of Series A Non-Voting Preferred
Shares ratably in accordance

<PAGE>
                                     - 10 -


with the respective amounts that would be payable on such Series A Non-Voting
Preferred Shares if such assets were sufficient to permit payment in full of all
amounts payable thereon.

         (2)      After the payment to the holders of Series A Non-Voting
Preferred Shares of the full amount of the liquidating distribution to which
they are entitled under this Section 1.5, the holders of the Series A Non-Voting
Preferred Shares as such shall have no right or claim to any of the remaining
assets of the Company and shall not be entitled to share in any further
distribution of assets of the Company.

         (3)      Any consolidation, merger or other business combination of the
Company with or into any other Person (as defined in Section 1.13 of this
Article C) or Persons shall be deemed to be a Liquidation for purposes of this
Section 1.5, except for any such merger, consolidation or other business
combination where, after the completion of such transaction, the holders of
voting shares in the capital of the Company immediately prior to such merger,
consolidation or other business combination will beneficially own a majority of
the voting shares in the capital of the surviving or acquiring entity.
Notwithstanding the foregoing, no consolidation, merger or other business
combination of the Company with or into any other Person shall be deemed to be a
Liquidation for the purposes of this Section 1.5 if the holders of not less than
85% of the issued and outstanding Series A Non-Voting Preferred Shares waive in
writing the provisions of this Section 1.5 with respect to such event.

         (4)      "Series A Non-Voting Liquidation Value" determined as of any
date shall mean, in respect of each Series A Non-Voting Preferred Share, the sum
of (A) an amount equal to the Initial Purchase Price plus an amount equal to six
percent (6%) of the Initial Purchase Price, compounded annually on each
anniversary of the Initial Issue Date prior to the date of determination and (B)
all declared but unpaid dividends per Series A Non-Voting Preferred Shares, if
any. The Series A Non-Voting Liquidation Value shall also be subject to
adjustment as provided in Section 1.5(6) of this Article C.

         (5)      Notwithstanding the foregoing, (i) the rate of six percent
(6%) referred to in Clause (A) of Section 1.5(4) of this Article C shall be read
as eight percent (8%) from such time and as long as an Event of Default shall
have occurred and be continuing and (ii) no amount shall be added to the Initial
Purchase Price pursuant to clause (A) of Section 1.5(4) of this Article C if the
Company shall consummate a Qualified IPO prior to the first anniversary of the
Initial Issue Date.

         (6)      The Series A Non-Voting Liquidation Value shall be multiplied
by a factor equal to the sum of (x) 1.00 and (y) the Additional Issuance Ratio
if and for so long as the Company is in default in the performance of or
compliance with Section 1.4(a), 1.4(b) or 1.4(c) of the Purchase Agreement.

1.6               CONVERSION

         (1)      If a Conversion Event occurs, each Series A Non-Voting
Preferred Share may, at the option of the Company, and in compliance with the
provisions of Section 1.6(4) of this Article C, be converted into a number of
Class A Non-Voting Shares equal to the Conversion Ratio. In addition, at the
option of the holder of any Series A Non-Voting Preferred Shares, such holder
shall have the right, at any time and from time to time, by written notice to
the Company,

<PAGE>
                                     - 11 -


to convert each Series A Non-Voting Preferred Share owned by such holder into
(a) a number of Class A Non-Voting Shares equal in the aggregate to the
Conversion Ratio or (b) Series B Subordinate Voting Preferred Shares on a one
for one basis, in each case without payment of any additional consideration.

         (2)      The Conversion Ratio, determined at any time, shall equal one
(1.00) plus an adjustment equal to six percent (6%) of the Conversion Ratio,
compounded annually on each anniversary of the Initial Issue Date prior to the
date of determination but, from such time and as long as an Event of Default
shall have occurred and be continuing, the rate of six percent (6%) referred to
above in this Section 1.6(2) shall be read as eight percent (8%); provided,
however, that if the Company consummates a Qualified IPO prior to the first
anniversary of the Initial Issue Date then no adjustment shall be made pursuant
to this sentence. The Conversion Ratio shall also be adjusted as provided below
in this Section 1.6(2). The Conversion Ratio shall be multiplied by a factor
equal to the sum of (x) 1.00 and (y) the Additional Issuance Ratio if and for so
long as the Company is in default in the performance of or compliance with
Section 1.4(a), 1.4(b) or 1.4(c) of the Purchase Agreement. The Conversion Ratio
shall also be subject to adjustment from time to time as follows:

                  (a) If the Company at any time or from time to time after the
Initial Issue Date (A) pays any dividend or makes any distribution in additional
Common Shares of the Company or of securities convertible into, or exchangeable
or exercisable for, shares of Common Shares of the Company, (B) subdivides the
outstanding Common Shares, (C) combines the outstanding Common Shares into a
smaller number of shares or (D) issues by reclassification of the Common Shares
any shares in the capital of the Company, then, and in each such case, the
Conversion Ratio in effect immediately prior to such event or the record date
therefor, whichever is earlier, shall be adjusted so that the holder of Series A
Non-Voting Preferred Shares thereafter convertible into Class A Non-Voting
Shares pursuant to this Section 1.6 of this Article C shall be entitled to
receive the number and type of Class A Non-Voting Shares or other securities of
the Company which such holder would have owned or have been entitled to receive
after the happening of any of the events described above had such Series A
Non-Voting Preferred Shares been converted into Class A Non-Voting Shares
immediately prior to the happening of such event or the record date therefore,
whichever is earlier. An adjustment made pursuant to this clause (a) shall
become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of Common Shares entitled to receive such dividend or distribution,
or (y) in the case of such subdivision, reclassification or combination, at the
close of business on the day upon which such corporate action becomes effective.

                  (b) If the Company issues to all (or substantially all)
holders of Common Shares any rights or subscriptions to purchase Common Shares
or Common Share Equivalents after the Initial Issue Date at a price per Common
Share (or having a conversion or exercise price per share in the case of Common
Share Equivalents) of less than either (i) the Series A Non-Voting Liquidation
Value or (ii) the Market Price of the Common Shares on the earlier of the date
of such issuance or the record date therefor (the "Applicable Date") then, in
each such case the Conversion Ratio shall be adjusted by multiplying (A) the
Conversion Ratio in effect at the close of business on the day immediately prior
to the Applicable Date by (B) a fraction, the numerator of which shall be the
sum of (1) the number of Common Shares outstanding at the close of business on
the date immediately prior to the Applicable Date and (2) the number of

<PAGE>
                                     - 12 -


additional Common Shares issued or issuable upon acceptance, conversion,
exchange or exercise of such rights or subscriptions (or upon conversion,
exchange or exercise of Common Share Equivalents issued or issuable pursuant to
such rights or subscriptions), and the denominator of which shall be the sum of
(x) the number of Common Shares outstanding at the close of business on the date
immediately prior to the Applicable Date and (y) the number of Common Shares
which would be purchasable for the aggregate consideration received by the
Company upon issuance of such Common Shares or Common Share Equivalents or
receivable by the Company for the total number of Common Shares issuable upon
acceptance, conversion, exchange or exercise of such rights or subscriptions (or
upon conversion, exchange or exercise of Common Share Equivalents issued or
issuable pursuant to such rights or subscriptions) if the price per share for
such purchase, conversion, exchange or exercise was equal to the greater of (i)
the Series A Non-Voting Liquidation Value or (ii) the Market Price of the Common
Shares as of the Applicable Date. An adjustment made pursuant to this clause (b)
shall become effective immediately after the close of business on the Applicable
Date.

                  (c) Except with respect to Deemed Outstanding Securities (as
defined below), if the Company issues any Common Shares (or Common Share
Equivalents) after the Initial Issue Date at a price per Common Share (or having
a conversion or exercise price per share in the case of Common Share
Equivalents) of less than either (i) the Series A Non-Voting Liquidation Value
or (ii) the Market Price of the Common Shares on the date of issuance of such
Common Shares (or Common Share Equivalents), then, in each such case, the
Conversion Ratio shall be adjusted by multiplying (A) the Conversion Ratio in
effect at the close of business on the day immediately prior to the date of
issuance of such Common Shares (or Common Share Equivalents) by (B) a fraction,
the numerator of which shall be the sum of (l) the number of Common Shares
outstanding at the close of business on the date immediately prior to the date
of issuance of such Common Shares (or Common Share Equivalents) and (2) the
number of such additional Common Shares and the number of Common Shares issued
or issuable upon conversion, exchange or exercise of such Common Share
Equivalents, and the denominator of which shall be the sum of (x) the number of
Common Shares outstanding on the date immediately prior to the date of issuance
of such Common Shares (or Common Share Equivalents) and (y) the number of Common
Shares which would be purchasable for the aggregate consideration received by
the Company upon issuance of such Common Shares or Common Share Equivalents or
receivable by the Company for the total number of Common Shares issuable or
issuable upon conversion, exchange or exercise of Common Share Equivalents if
the price per share for such purchase, conversion, exchange or exercise was
equal to the greater of (i) the Series A Non-Voting Liquidation Value or (ii)
the Market Price of the Common Shares as of the date of issuance of such Common
Shares (or Common Share Equivalents). An adjustment made pursuant to this clause
(c) shall be made on the next Business Day following the date on which any such
issuance is made and shall be effective retroactively to the close of business
on the date of such issuance. "Deemed Outstanding Securities" shall mean (i) the
stock options and Class A Non-Voting Shares to be issued upon the exercise of
such stock options, initially issued or issuable, or Permitted Reissued Options
(as defined in the Purchase Agreement) pursuant to the 1998 Long Term Incentive
and Share Award Plan (Amended) of the Company exercisable for a maximum of
4,445,813 Class A Non-Voting Shares; (ii) any Series A Non-Voting Preferred
Shares issued pursuant to the Purchase Agreement or any Class A Non-Voting
Shares or Series B Subordinate Voting Preferred Shares issued on the conversion
of the Series A Non-Voting Preferred Shares; (iii) 4,500,000 Common Shares
issued, or to be issued, in consideration for the acquisition by the Company of
fiber assets and related rights and

                                     - 13 -


obligations from Ledcor Industries Limited or Ledcor Industries Inc. under the
amended and restated Share Purchase Agreement dated September 7, 1999 between
Ledcor Industries Limited, Ledcor Industries Inc. and the Company; (iv) any
Class A Non-Voting Shares issued on conversion of the Series B Subordinate
Voting Shares; (v) any Common Shares or Common Share Equivalent issued pursuant
to any Minority Roll-Up Transaction; (vi) any Common Shares, or Common Share
Equivalents issued pursuant to an event described in clauses (a) or (b) of this
Section 1.6(2); or (vii) 26,080,000 Class A Non-Voting Shares and 4,920,000
Class C Multiple Voting Shares issued to Gregory B. Maffei.

                  (d) For purposes of this Section 1.6(2) the aggregate
consideration receivable by the Company in connection with the issuance of
Common Shares and/or Common Share Equivalents shall be deemed to be equal to the
sum of the aggregate offering price (before deduction of underwriting discounts
or commissions and expenses payable to third parties, if any) of all such Common
Shares and/or Common Share Equivalents plus the minimum aggregate amount, if
any, payable upon conversion, exchange or exercise of any such Common Share
Equivalents. Upon the expiration or termination of any unconverted, unexchanged
or unexercised Common Share Equivalents for which an adjustment has been made
pursuant to clause (b) or clause (c) of this Section 1.6(2), the adjustments
shall forthwith be reversed to effect such Conversion Ratio as would have been
in effect at the time of such expiration or termination had such Common Share
Equivalents, to the extent outstanding immediately prior to such expiration or
termination, never been issued. The consideration received by the Company in
connection with the sale or issuance of Common Shares (or Common Share
Equivalents) shall be computed as follows:

                           (A) insofar as such consideration consists of cash,
such consideration shall equal the aggregate amount of cash received by the
Company prior to amounts paid or payable for accrued interest or accrued
dividends and prior to any commissions or expenses paid by the Company;

                           (B) insofar as such consideration consists of
property other than cash, such consideration shall be calculated at the fair
value thereof at the time of such issue, as determined in good faith by the
Board of Directors, which shall be based upon a written opinion of an investment
banking or appraisal firm of national standing in the United States if such
consideration is given a value exceeding $10 million; and

                           (C) in the event Common Shares or Common Share
Equivalents are issued together with other securities or other assets of the
Company for consideration that is allocable to both such Common Shares and
Common Share Equivalents, and to such other securities and assets, the portion
of such consideration allocable to such Common Shares or Common Share
Equivalents shall be that set forth in the instruments and agreements issued or
entered into in connection with such transaction, and if no such allocation is
so set forth, then the portion of such consideration allocable to such Common
Shares or Common Share Equivalents, calculated as provided in clauses (A) and
(B) above, as determined in good faith by the Board of Directors.

                  (e) For purposes of this Section 1.6(2) the number of Common
Shares at any time outstanding shall mean the aggregate of all Common Shares
then outstanding (other than any Common Shares then owned or held by or for the
account of the Company).

                                     - 14 -


                  (f) If the Company shall take a record of the holders of its
Common Shares for the purpose of entitling them to receive a dividend or other
distribution and shall thereafter, and before such dividend or distribution is
paid or delivered to shareholders entitled thereto, legally abandon its plan to
pay or deliver such dividend or distribution, then no adjustment in the
Conversion Ratio then in effect shall be made by reason of the taking of such
record, and any such adjustment previously made as a result of the taking of
such record shall be reversed.

         (3) Subject to compliance with the provisions of Section 1.6(5) of this
Article C, each holder of Series A Non-Voting Preferred Shares shall be entitled
at any time and from time to time to have all or any part of the Series A
Non-Voting Preferred Shares held by such holder converted into validly issued,
fully paid and non-assessable Series B Subordinate Voting Preferred Shares upon
the basis of one Series B Subordinate Voting Preferred Share for each Series A
Non-Voting Preferred Share in respect of which the conversion right is
exercised.

         (4) Before the Company shall be entitled to convert Series A Non-Voting
Preferred Shares into Class A Non-Voting Shares pursuant to Section 1.6(1) of
this Article C, the Company shall not less than 10 days and not more than 20
days before the date specified for conversion (the "Conversion Date") send by
prepaid first class mail or deliver to the registered address of each person who
at the date not more than 7 days prior to the date of mailing or delivery is a
registered holder of Series A Non-Voting Preferred Shares to be converted a
notice in writing of the intention of the Company to convert the Series A
Non-Voting Preferred Shares registered in the name of such holder. Accidental
failure or omission to give such notice to one (1) or more holders shall not
affect the validity of such conversion, but upon such failure or omission being
discovered notice shall be given forthwith to such holder or holders and such
notice shall have the same force and effect as if given in due time. Such notice
shall set out the number of Series A Non-Voting Preferred Shares held by the
person to whom it is addressed which are to be converted, the Conversion Ratio,
the Conversion Date and the place or places at which holders of Series A
Non-Voting Preferred Shares may present and surrender such shares for
conversion. After the giving of such notice in writing, the election of the
Company shall be irrevocable.

                  (a) Within three (3) days following the Conversion Date, the
Company shall, on presentation and surrender of the certificate or certificates
representing the Series A Non-Voting Preferred Shares called for conversion at
the place or places specified in the notice of conversion, issue and deliver to
such holder of Series A Non-Voting Preferred Shares, or to the nominee or
nominees of such holder, a certificate or certificates for the number of Class A
Non-Voting Shares entitled as aforesaid. Such conversion shall be deemed to have
been made immediately prior to the close of business on the Conversion Date or,
if the Conversion Event is a Qualified IPO, then immediately prior to the
consummation of the Qualified IPO, and the person or persons entitled to receive
the Class A Non-Voting Shares issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such Class A Non-Voting Shares
as of such date. The issuance of certificates for Class A Non-Voting Shares,
upon conversion of the Series A Non-Voting Preferred Shares, shall be made
without charge to the holder but the holder shall pay any governmental or other
tax imposed on or in respect of such conversion. If less than all of the Series
A Non-Voting Preferred Shares represented by any certificate are to be
converted, the holder shall be entitled to receive a new certificate
representing the number of Series A Non-Voting Preferred Shares represented by
the original certificate which are not to be converted.

                                     - 15 -


                  (b) The Company shall have the right at any time on or after
the Conversion Date to deposit the certificate or certificates representing
Class A Non-Voting Shares into trust for holders of the Series A Non-Voting
Preferred Shares called for conversion, which have not at the date of such
deposit been surrendered in connection with such conversion. Certificates
deposited into trust shall be held by the Company or other designated person
named in the notice of conversion or in a subsequent notice to the registered
holders of the Series A Non-Voting Preferred Shares in respect of which the
deposit was made. Upon such deposit being made, the Series A Non-Voting
Preferred Shares in respect of which such deposit shall have been made shall be
deemed to have been converted and the rights of the holders thereof after such
deposit or such Conversion Date, as the case may be shall be, limited to
receiving the certificate or certificates representing the Class A Non-Voting
Shares to which they are entitled upon presentation and surrender of the
certificate or certificates representing the Series A Non-Voting Preferred
Shares being converted.

         (5)      Before any holder of Series A Non-Voting Preferred Shares
shall be entitled to convert the same into Class A Non-Voting Shares or Series B
Subordinate Voting Preferred Shares such holder shall surrender the certificate
or certificates therefor, duly endorsed, at the office of the Company or of any
transfer agent for the Series A Non-Voting Preferred Shares, together with a
written notice to the Company stating therein: the name or names in which the
certificate or certificates for Common Shares or Preferred Shares are to be
issued; the number of Series A Non-Voting Preferred Shares to be converted; and
notice of such holder's election to convert such Series A Non-Voting Preferred
Shares. After giving such notice in writing, the election of the holder of
Series A Non-Voting Preferred Shares shall be irrevocable although may be
subject to the condition described below when the conversion is in connection
with an underwritten public offering. The Company shall, within three (3) days
of such written notice, issue and deliver at such office to such holder of
Series A Non-Voting Preferred Shares, or to the nominee or nominees of such
holder, a certificate or certificates for the number of Class A Non-Voting
Shares or Series B Subordinate Voting Preferred Shares, as the case may be, to
which such holder shall be entitled as aforesaid. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the Series A Non-Voting Preferred Shares to be converted,
and the person or persons entitled to receive the shares of Class A Non-Voting
Shares or Series B Subordinate Voting Preferred Shares, as the case may be,
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such Class A Non-Voting Shares or Series B Subordinate
Voting Preferred Shares, as the case may be, as of such date. If the conversion
is in connection with an underwritten public offering of securities (other than
a Qualified IPO), the conversion into Common Shares may, at the option of any
holder tendering Series A Non-Voting Preferred Shares for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive the
Common Shares upon conversion of the Series A Non-Voting Preferred Shares shall
not be deemed to have converted such Series A Non-Voting Preferred Shares until
immediately prior to the closing of such sale of securities. The issuance of
certificates for Class A Non-Voting Shares or Series B Subordinate Voting
Preferred Shares, as the case may be, upon conversion of the Series A Non-Voting
Preferred Shares shall be made without charge to the holder but the holder shall
pay any stamp, documentary or similar tax imposed on or in respect of such
conversion. If less than all of the Series A Non-Voting Preferred Shares
represented by any certificate are to be converted, the holder shall be entitled
to receive a new certificate representing the number of Series A Non-Voting
Preferred Shares which are not to be converted.

                                     - 16 -


         (6)      The Company shall at no time close its transfer books against
the transfer of any Series A Non-Voting Preferred Shares, or of any Class A
Non-Voting Shares or Series B Subordinate Voting Preferred Shares issuable upon
the conversion of any Series A Non-Voting Preferred Shares, in any manner which
interferes with the timely conversion of such Series A Non-Voting Preferred
Shares, except as may otherwise be required to comply with applicable laws or
the provisions of the Attachment to these Articles.

         (7)      As used in this Section 1.6 the term "Class A Non-Voting
Shares" shall mean and include the Company's Class A Non-Voting Shares as
constituted on the Initial Issue Date, and shall also include any shares of any
class of the capital of the Company thereafter authorized which shall neither be
limited to a fixed sum or percentage in respect of the rights of the holders
thereof to participate in dividends nor be entitled to a preference in the
distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of the Company provided that the Class A Non-Voting
Shares receivable upon conversion of Series A Non-Voting Preferred Shares shall
include only shares designated as Class A Non-Voting Shares of the Company on
the Initial Issue Date, or in case of any reorganization or reclassification of
the outstanding shares thereof, the shares, securities or assets to be issued in
exchange for such Class A Non-Voting Shares pursuant thereto.

         (8)      If the Company shall be a party to any transaction including
without limitation, an amalgamation, arrangement, consolidation, sale of all or
substantially all of the Company's assets or a reorganization, reclassification
or recapitalization of the capital of the Company but excluding any transaction
for which provision for adjustment is otherwise made in this Section 1.6 (each
of the foregoing being referred to as a "Transaction"), in each case, as a
result of which Class A Non-Voting Shares are converted into the right to
receive shares, securities or other property (including, without limitation,
cash or any combination thereof), each Series A Non-Voting Preferred Share shall
thereafter be convertible into the number of shares or other securities or
property to which a holder of the number of Class A Non-Voting Shares of the
Company deliverable upon conversion of such Series A Non-Voting Preferred Shares
would have been entitled upon such Transaction; and, in any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions set forth in this Section 1.6 with respect
to the rights and interest thereafter of the holders of the Series A Non-Voting
Preferred Shares, to the end that the provisions set forth in this Section 1.6
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any shares or other property thereafter deliverable upon the conversion of the
Series A Non-Voting Preferred Shares. The Company shall not effect any
Transaction unless prior to or simultaneously with the consummation thereof the
Company or purchaser, as the case may be, shall provide in its charter document
that each Series A Non-Voting Preferred Share shall be converted into such
shares, securities or property as, in accordance with the foregoing provisions,
each such holder is entitled to receive. The provisions of this Section 1.6(8)
shall similarly apply to successive Transactions.

         (9)      No fractional shares shall be issued upon the conversion of
any share or shares of the Series A Non-Voting Preferred Shares, and the number
of Common Shares to be issued shall be rounded down to the nearest whole share.
Whether or not fractional shares are issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Non-Voting
Preferred Shares the holder is at the time converting into Common Shares or
Series

<PAGE>
                                     - 17 -


B Subordinate Voting Preferred Shares and the number of Common Shares or
Series B Subordinate Voting Preferred Shares issuable upon such aggregate
conversion.

         (10)     If an event not specified in this Section 1.6 occurs that has
substantially the same economic effect on the Series A Non-Voting Preferred
Shares as those specifically enumerated above in this Section 1.6, then this
Section 1.6 shall be construed liberally, mutatis mutandis, in order to give the
holders of Series A Non-Voting Preferred Shares the intended benefit of the
protections provided under this Section 1.6. In such event, the Company's Board
of Directors shall make an appropriate adjustment in the Conversion Ratio so as
to protect the rights of the holders of Series A Non-Voting Preferred Shares;
provided that no such adjustment shall increase or decrease the Conversion Ratio
as otherwise determined pursuant to this Section 1.6 or decrease the number of
Class A Non-Voting Shares issuable upon conversion of each Series A Non-Voting
Preferred Share.

         (11)     The Company will not, by amendment of its Articles or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Company, and will at all times in good faith assist
in the carrying out of all the provisions of this Section 1.6 and in the taking
of all such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of the Series A Non-Voting Preferred Shares
against impairment.

         (12)     All calculations under this Section 1.6 shall be made to (a)
the nearest cent or (b) the nearest one hundredth of a share or (c) the nearest
one percent, as the case may be.

1.7               NOTICE OF CERTAIN EVENTS

                  In case, at any time while any Series A Non-Voting Preferred
Shares are outstanding,

         (1)      the Company shall declare a dividend (or any other
distribution) on its Common Shares;

         (2)      the Company shall authorize the issuance to the holders of its
Common Shares, of Common Share Equivalents, or rights or warrants to subscribe
for or purchase Common Shares or of any other subscriptions rights or warrants;

         (3)      the Company shall authorize any reorganization,
reclassification or recapitalization of its Common Shares;

         (4)      the Company shall authorize the consolidation or merger of the
Company into or with any other person, the sale or transfer of all or
substantially all of its business or assets to another person, or any other
similar business combination or transaction; or

         (5)      the Company shall authorize the voluntary or involuntary
dissolution, liquidation or winding up on the Company,

then the Company shall promptly deliver to the transfer agent of the Series A
Non-Voting Preferred Shares, if any, and to each of the holders of Series A
Non-Voting Preferred Shares at

<PAGE>
                                     - 18 -


their last addresses as they shall appear on the register for the Series A
Non-Voting Preferred Shares, at least 15 days before the date hereafter
specified (or the earlier of the dates hereinafter specified, in the event that
more than one date is specified), a notice describing such event and stating (A)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Shares of record to be entitled to such
dividend, distribution, rights or warrants are to be determined, or (B) the date
on which any such reclassification, reorganization, recapitalization,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is
expected to become effective, and the date as of which it is expected that
holders of Common Shares of record shall be entitled to exchange their Common
Shares for securities or other property (including cash), if any, deliverable
upon such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up.

1.8               REPORTS AS TO ADJUSTMENT

                  Upon any adjustment of the Conversion Ratio then in effect
pursuant to the provisions of Section 1.6 of this Article C then, and in each
such case, the Company shall promptly deliver to each of the holders of the
Series A Non-Voting Preferred Shares, a certificate signed by an officer of the
Company setting forth in reasonable detail the event requiring the adjustment,
the method by which such adjustment was calculated and the Conversion Ratio then
in effect following such Adjustment. Where appropriate, such notice to holders
of the Series A Non-Voting Preferred Shares may be given in advance.

1.9               MANDATORY REDEMPTION

                  On November 2, 2009 (the "Redemption Date"), the Company shall
redeem all the Series A Non-Voting Preferred Shares then outstanding and not
theretofore surrendered for conversion, as follows: Thirty days prior to the
Redemption Date, the Company shall give written notice to all holders of Series
A Non-Voting Preferred Shares which shall specify the Redemption Date. For each
Series A Non-Voting Preferred Share which is to be redeemed, the Company shall
be obligated on the Redemption Date to pay and deliver share certificates to the
holder thereof (upon surrender by such holder at the Company's principal
executive office of the certificate representing such share or an Affidavit of
Loss with respect thereto) (a) an amount in immediately available funds equal to
the Series A Non-Voting Liquidation Value, and (b) such number of Class A
Non-Voting Shares as have an aggregate Market Price (as determined on the day
immediately before the Redemption Date) equal to the excess of the Market Price
(as determined on the day immediately before the Redemption Date) of the Series
A Non-Voting Preferred Share over the Series A Non-Voting Liquidation Value. All
Class A Non-Voting Shares shall, when issued as contemplated herein, be validly
issued, fully paid and non-assessable. If the funds of the Company legally
available for redemption of the Series A Non-Voting Preferred Shares on the
Redemption Date are insufficient to redeem the total number of such shares to be
redeemed on such date, then those funds which are legally available shall be
used to redeem the maximum possible number of such shares ratably among the
holders thereof, based upon the aggregate Series A Non-Voting Liquidation Value
of such Series A Non-Voting Preferred Shares held by each such holder. At any
time thereafter when additional funds of the Company are legally available for
the redemption of Series A Non-Voting Preferred Shares, such funds shall
immediately be used to redeem on a similar ratable basis the balance of such
shares. Notwithstanding the foregoing, each holder of Series A Non-Voting
Preferred Shares shall be entitled to convert all or any portion of such
holder's shares pursuant to Section 1.6 of this Article C prior to the
Redemption Date and thereafter until such Series A Non-Voting Preferred Shares
are redeemed.

1.10              RESERVATION OF SHARES ISSUABLE UPON CONVERSION

                  The Company shall at all times reserve and keep available out
of its authorized but unissued Class A Non-Voting Shares and out of its
authorized but unissued Preferred Shares solely for the purpose of effecting the
conversion of the issued or issuable Series A Non-Voting Preferred Shares, such
number of its Class A Non-Voting Shares and Series B Subordinate Voting
Preferred Shares, as the case may be, as shall from time to time be sufficient
to effect the conversion of all outstanding Series A Non-Voting Preferred
Shares, and if at any time the number of authorized but unissued Class A
Non-Voting Shares or Series B Subordinate Voting Preferred Shares shall not be
sufficient to effect the conversion of all then outstanding Series A Non-Voting
Preferred Shares, the Company will take all such corporate action as may be
necessary to increase its authorized but unissued Class A Non-Voting Shares or
Series B Subordinate Voting Preferred Shares to such number of shares as shall
be sufficient for such purpose. All Class A Non-Voting Shares and Series B
Subordinate Voting Preferred Shares shall, when issued upon conversion as
contemplated herein, be validly issued, fully paid and non-assessable.

1.11              LISTING ON SECURITIES EXCHANGES, ETC.

                  The Company will list on each national securities exchange on
which any Common Shares may at any time be listed, subject to official notice of
issuance upon the conversion of the Series A Non-Voting Preferred Shares, all
Class A Non-Voting Shares from time to time issuable upon the conversion of
Series A Non-Voting Preferred Shares and will maintain such listing as long as
any Class A Non-Voting Shares are listed.

1.12              CERTAIN COVENANTS

                  Any registered holder of Series A Non-Voting Preferred Shares
may proceed to protect and enforce its rights and the rights of any other
holders of Series A Non-Voting Preferred Shares with any and all remedies
available at law or in equity.

1.13              DEFINITIONS

                  In addition to any other terms defined herein for purposes of
this Article C, the following terms shall have the meaning indicated (references
to particular sections of the Purchase Agreement or Shareholders Agreement shall
include any amended, successor or substitute provisions in such agreements, as
they may be amended from time to time in accordance with their respective
terms):

         (1)      Upon (i) any liquidation, dissolution or winding up of the
Company, whether voluntary or involuntary, (ii) a sale of all or substantially
all of the assets of the Company or (iii) a reorganization of the Company
required by any court or administrative body in order to comply with any
provision of law (each of the events referred to in clauses (i), (ii) and (iii)
being referred to as a "Liquidation"), the holders of Series B Subordinate

assets of the Company available for distribution to its shareholders, before any
payment or distribution shall be made on any Junior Shares, the greater of (i)

Share could be converted pursuant to the provisions of Section 1.6 of this
Article D. If, upon any Liquidation of the Company, the assets of the Company
available for distribution shall be insufficient to pay in full the Series B

Subordinate Voting Preferred Shares if such assets were sufficient to permit
payment in full of all amounts payable thereon.

         (2)      After the payment to the holders of Series B Subordinate
Voting Preferred Shares of the full amount of the liquidating distribution to
which they are entitled under this Section 1.5, the holders of the Series B
Subordinate Voting Preferred Shares as such shall have no right or claim to any
of the remaining assets of the Company and shall not be entitled to share in any
further distribution of assets of the Company.

         (3)      Any consolidation, merger or other business combination of the
Company with or into any other Person or Persons shall be deemed to be a
Liquidation for purposes of this Section 1.5, except for any such merger,
consolidation or other business combination where, after the completion of such
transaction, the holders of voting shares in the capital of the Company
immediately prior to such merger, consolidation or other business combination
will beneficially own a majority of the voting shares in the capital of the
surviving or acquiring entity. Notwithstanding the foregoing, no consolidation,
merger or other business combination of the Company with or into any other
Person shall be deemed to be a Liquidation for the purposes of this Section 1.5
if the holders of not less than 85% of the issued and outstanding Series B
Subordinate Voting Preferred Shares waive in writing the provisions of this
Section 1.5 with respect to such event.

         (4)      "Series B Subordinate Voting Liquidation Value" determined as
of any date shall mean, in respect of each Series B Subordinate Voting Preferred
Share, the sum of (A) an amount equal to the Initial Purchase Price plus an
amount equal to six percent (6%) of the Initial Purchase Price, compounded
annually on each anniversary of the Initial Issue Date prior to the date of
determination and (B) all declared but unpaid dividends per Series B Subordinate
Voting Preferred Shares, if any. The Series B Subordinate Voting Liquidation

<PAGE>
                                     - 25 -


         (5)      Notwithstanding the foregoing, (i) the rate of six percent
(6%) referred to in Clause (A) of Section 1.5(4) of this Article D shall be read
as eight percent (8%) from such time and as long as an Event of Default shall
have occurred and be continuing and (ii) no amount shall be added to the Initial
Purchase Price pursuant to clause (A) of Section 1.5(4) of this Article D if the
Company shall consummate a Qualified IPO prior to the first anniversary of the
Initial Issue Date.

         (6)      The Series B Subordinate Voting Liquidation Value shall be
multiplied by a factor equal to the sum of (x) 1.00 and (y) the Additional
Issuance Ratio if and for so long as the Company is in default in the
performance of or compliance with Section 1.4(a), 1.4(b) or 1.4(c) of the
Purchase Agreement.

1.6               CONVERSION

         (1)      If a Conversion Event occurs, each Series B Subordinate Voting
Preferred Share may, at the option of the Company, and in compliance with the
provisions of Section 1.6(4) of this Article D, be converted into a number of
Class B Subordinate Voting Shares equal to the Conversion Ratio. In addition, at
the option of the holder of any Series B Subordinate Voting Preferred Shares,
such holder shall have the right, at any time and from time to time, by written
notice to the Company, to convert each Series B Subordinate Voting Preferred
Share owned by such holder into (a) a number of Class B Subordinate Voting
Shares equal in the aggregate to the Conversion Ratio or (b) Series A Non-Voting
Preferred Shares on a one for one basis, in each case without payment of any
additional consideration.

         (2)      The Conversion Ratio, determined at any time, shall equal one
(1.00) plus an adjustment equal to six percent (6%) of the Conversion Ratio,
compounded annually on each anniversary of the Initial Issue Date prior to the
date of determination but, from such time and as long as an Event of Default
shall have occurred and be continuing, the rate of six percent (6%) referred to
above in this Section 1.6(2) shall be read as eight percent (8%); provided,
however, that if the Company consummates a Qualified IPO prior to the first
anniversary of the Initial Issue Date then no adjustment shall be made pursuant
to this sentence. This Conversion Ratio shall also be adjusted as provided below
in this Section 1.6(2). The Conversion Ratio shall be multiplied by a factor
equal to the sum of (x) 1.00 and (y) the Additional Issuance Ratio if and for so
long as the Company is in default in the performance of or compliance with
Section 1.4(a), 1.4(b) or 1.4(c) of the Purchase Agreement. The Conversion Ratio
shall also be subject to adjustment from time to time as follows:

                  (a)  If the Company at any time or from time to time after the
Initial Issue Date (A) pays any dividend or makes any distribution in additional
Common Shares of the Company or of securities convertible into, or exchangeable
or exercisable for, shares of Common Shares of the Company, (B) subdivides the
outstanding Common Shares, (C) combines the outstanding Common Shares into a
smaller number of shares or (D) issues by reclassification of the Common Shares
any shares in the capital of the Company, then, and in each such case, the
Conversion Ratio in effect immediately prior to such event or the record date
therefor, whichever is earlier, shall be adjusted so that the holder of Series B
Subordinate Voting Preferred Shares thereafter convertible into Class B
Subordinate Voting Shares pursuant to this Section 1.6 shall be entitled to
receive the number and type of Class B Subordinate Voting Shares or other
securities of the Company which such holder would have owned or have been
entitled to receive after the

<PAGE>
                                     - 26 -


happening of any of the events described above had such Series B Subordinate
Voting Preferred Shares been converted into Class B Subordinate Voting Shares
immediately prior to the happening of such event or the record date therefore,
whichever is earlier. An adjustment made pursuant to this clause (a) shall
become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of Common Shares entitled to receive such dividend or distribution,
or (y) in the case of such subdivision, reclassification or combination, at the
close of business on the day upon which such corporate action becomes effective.

                  (b) If the Company issues to all (or substantially all)
holders of Common Shares any rights or subscriptions to purchase Common Shares
or Common Share Equivalents after the Initial Issue Date at a price per Common
Share (or having a conversion or exercise price per share in the case of Common
Share Equivalents) of less than either (i) the Series B Subordinate Voting
Liquidation Value or (ii) the Market Price of the Common Shares on the earlier
of the date of such issuance or the record date therefor (the "Applicable Date")
then, in each such case the Conversion Ratio shall be adjusted by multiplying
(A) the Conversion Ratio in effect at the close of business on the day
immediately prior to the Applicable Date by (B) a fraction, the numerator of
which shall be the sum of (1) the number of Common Shares outstanding at the
close of business on the date immediately prior to the Applicable Date and (2)
the number of additional Common Shares issued or issuable upon acceptance,
conversion, exchange or exercise of such rights or subscriptions (or upon
conversion, exchange or exercise of Common Share Equivalents issued or issuable
pursuant to such rights or subscriptions), and the denominator of which shall be
the sum of (x) the number of Common Shares outstanding at the close of business
on the date immediately prior to the Applicable Date and (y) the number of
Common Shares which would be purchasable for the aggregate consideration
received by the Company upon issuance of such Common Shares or Common Share
Equivalents or receivable by the Company for the total number of Common Shares
issuable upon acceptance conversion, exchange or exercise of such rights or
subscriptions (or upon conversion, exchange or exercise of Common Share
Equivalents issued or issuable pursuant to such rights or subscriptions) if the
price per share for such purchase, conversion, exchange or exercise was equal to
the greater of (i) the Series B Subordinate Voting Liquidation Value or (ii) the
Market Price of the Common Shares as of the Applicable Date. An adjustment made
pursuant to this clause (b) shall become effective immediately after the close
of business on the Applicable Date.

                  (c) Except with respect to Deemed Outstanding Securities (as
defined below), if the Company issues any Common Shares (or Common Share
Equivalents) after the Initial Issue Date at a price per Common Share (or having
a conversion or exercise price per share in the case of Common Share
Equivalents) of less than either (i) the Series B Subordinate Voting Liquidation
Value or (ii) the Market Price of the Common Shares on the date of issuance of
such Common Shares (or Common Share Equivalents), then, in each such case, the
Conversion Ratio shall be adjusted by multiplying (A) the Conversion Ratio in
effect at the close of business on the day immediately prior to the date of
issuance of such Common Shares (or Common Share Equivalents) by (B) a fraction,
the numerator of which shall be the sum of (l) the number of Common Shares
outstanding at the close of business on the date immediately prior to the date
of issuance of such Common Shares (or Common Share Equivalents) and (2) the
number of such additional Common Shares and the number of Common Shares issued
or issuable upon conversion, exchange or exercise of such Common Share
Equivalents, and the denominator of which shall be the sum of (x) the number of
Common Shares outstanding on the date

<PAGE>
                                     - 27 -


immediately prior to the date of issuance of such Common Shares (or Common Share
Equivalents) and (y) the number of Common Shares which would be purchasable for
the aggregate consideration received by the Company upon issuance of such Common
Shares or Common Share Equivalents or receivable by the Company for the total
number of Common Shares issuable or issuable upon conversion, exchange or
exercise of Common Share Equivalents if the price per share for such purchase,
conversion, exchange or exercise was equal to the greater of (i) the Series B
Subordinate Voting Liquidation Value or (ii) the Market Price of the Common
Shares as of the date of issuance of such Common Shares (or Common Share
Equivalents). An adjustment made pursuant to this clause (c) shall be made on
the next Business Day following the date on which any such issuance is made and
shall be effective retroactively to the close of business on the date of such
issuance. "Deemed Outstanding Securities" shall mean (i) the stock options and
Class A Non-Voting Shares to be issued upon the exercise of such stock options,
initially issued or issuable, or Permitted Reissued Options (as defined in the
Purchase Agreement) pursuant to the 1998 Long Term Incentive and Share Award
Plan (Amended) of the Company exercisable for a maximum of 4,445,813 Class A
Non-Voting Shares; (ii) any Series A Non-Voting Preferred Shares issued pursuant
to the Purchase Agreement or any Class B Subordinate Voting Shares or Series A
Non-Voting Preferred Shares issued on the conversion of the Series B Subordinate
Voting Preferred Shares; (iii) 4,500,000 Common Shares issued, or to be issued,

Class C Multiple Voting Shares issued to Gregory B. Maffei.

                  (d) For purposes of this Section 1.6(2) the aggregate
consideration receivable by the Company in connection with the issuance of
Common Shares and/or Common Share Equivalents shall be deemed to be equal to the
sum of the aggregate offering price (before deduction of underwriting discounts
or commissions and expenses payable to third parties, if any) of all such Common
Shares and/or Common Share Equivalents plus the minimum aggregate amount, if
any, payable upon conversion, exchange or exercise of any such Common Share
Equivalents. Upon the expiration or termination of any unconverted, unexchanged
or unexercised Common Share Equivalents for which an adjustment has been made
pursuant to clause (b) or clause (c) of this Section 1.6(2), the adjustments
shall forthwith be reversed to effect such Conversion Ratio as would have been
in effect at the time of such expiration or termination had such Common Share
Equivalents, to the extent outstanding immediately prior to such expiration or
termination, never been issued. The consideration received by the Company in
connection with the sale or issuance of Common Shares (or Common Share
Equivalents) shall be computed as follows:

                           (A) insofar as such consideration consists of cash,
such consideration shall equal the aggregate amount of cash received by the
Company prior to amounts paid or payable for accrued interest or accrued
dividends and prior to any commissions or expenses paid by the Company;

<PAGE>
                                     - 28 -


                           (B) insofar as such consideration consists of
property other than cash, such consideration shall be calculated at the fair
value thereof at the time of such issue, as determined in good faith by the
Board of Directors, which shall be based upon a written opinion of an investment
banking or appraisal firm of national standing in the United States if such
consideration is given a value exceeding $10 million; and

                           (C) in the event Common Shares or Common Share
Equivalents are issued together with other securities or other assets of the
Company for consideration that is allocable to both such Common Shares and
Common Share Equivalents, and to such other securities and assets, the portion
of such consideration allocable to such Common Shares or Common Share
Equivalents shall be that set forth in the instruments and agreements issued or
entered into in connection with such transaction, and if no such allocation is
so set forth, then the portion of such consideration allocable to such Common
Shares or Common Share Equivalents, calculated as provided in clauses (A) and
(B) above, as determined in good faith by the Board of Directors.

                  (e)      For purposes of this Section 1.6(2) the number of
Common Shares at any time outstanding shall mean the aggregate of all Common
Shares then outstanding (other than any Common Shares then owned or held by or
for the account of the Company).

                  (f)      If the Company shall take a record of the holders of
its Common Shares for the purpose of entitling them to receive a dividend or
other distribution and shall thereafter, and before such dividend or
distribution is paid or delivered to shareholders entitled thereto, legally
abandon its plan to pay or deliver such dividend or distribution, then no
adjustment in the Conversion Ratio then in effect shall be made by reason of the
taking of such record, and any such adjustment previously made as a result of
the taking of such record shall be reversed.

         (3)      Subject to compliance with the provisions of Section 1.6(5) of
this Article D, each holder of Series B Subordinate Voting Preferred Shares
shall be entitled at any time and from time to time to have all or any part of
the Series B Subordinate Voting Preferred Shares held by such holder converted
into validly issued, fully paid and non-assessable Series A Non-Voting Preferred
Shares upon the basis of one Series A Non-Voting Preferred Share for each Series
B Subordinate Voting Preferred Share in respect of which the conversion right is
exercised.

         (4)      Before the Company shall be entitled to convert Series B
Subordinate Voting Preferred Shares into Class B Subordinate Voting Shares
pursuant to Section 1.6(1) of this Article D, the Company shall not less than 10
days and not more than 20 days before the date specified for conversion (the
"Conversion Date") send by prepaid first class mail or deliver to the registered
address of each person who at the date not more than 7 days prior to the date of
mailing or delivery is a registered holder of Series B Subordinate Voting
Preferred Shares to be converted a notice in writing of the intention of the
Company to convert the Series B Subordinate Voting Preferred Shares registered
in the name of such holder. Accidental failure or omission to give such notice
to one (1) or more holders shall not affect the validity of such conversion, but
upon such failure or omission being discovered notice shall be given forthwith
to such holder or holders and such notice shall have the same force and effect
as if given in due time. Such notice shall set out the number of Series B
Subordinate Voting Preferred Shares held by the person to whom it is addressed
which are to be converted, the Conversion Ratio, the Conversion Date and the
place or places at which holders of Series B Subordinate Voting Preferred Shares
may

<PAGE>
                                     - 29 -


present and surrender such shares for conversion. After the giving of such
notice in writing, the election of the Company shall be irrevocable.

                  (a)      Within three (3) days following the Conversion Date,
the Company shall, on presentation and surrender of the certificate or
certificates representing the Series B Subordinate Voting Preferred Shares
called for conversion at the place or places specified in the notice of
conversion, issue and deliver to such holder of Series B Subordinate Voting
Preferred Shares, or to the nominee or nominees of such holder, a certificate or
certificates for the number of Class B Subordinate Voting Shares entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the Conversion Date, and the person or persons
entitled to receive the Class B Subordinate Voting Shares issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such Class B Subordinate Voting Shares as of such date. The issuance of
certificates for Class B Subordinate Voting Shares, upon conversion of the
Series B Subordinate Voting Preferred Shares, shall be made without charge to
the holder but the holder shall pay any stamp, documentary or similar tax
imposed on or in respect of such conversion. If less than all of the Series B
Subordinate Voting Preferred Shares represented by any certificate are to be
converted, the holder shall be entitled to receive a new certificate
representing the number of Series B Subordinate Voting Shares represented by the
original certificate which are not to be converted.

                  (b)      The Company shall have the right at any time on or
after the Conversion Date to deposit the certificate or certificates
representing Class B Subordinate Voting Shares into trust for holders of the
Series B Subordinate Voting Preferred Shares called for conversion, which have
not at the date of such deposit been surrendered in connection with such
conversion. Certificates deposited into trust shall be held by the Company or
other designated person named in the notice of conversion or in a subsequent
notice to the registered holders of the Series B Subordinate Voting Preferred
Shares in respect of which the deposit was made. Upon such deposit being made,
the Series B Subordinate Voting Preferred Shares in respect of which such
deposit shall have been made shall be deemed to have been converted and the
rights of the holders thereof after such deposit or such Conversion Date, as the
case may be, shall be limited to receiving the certificate or certificates
representing the Class B Subordinate Voting Shares to which they are entitled
upon presentation and surrender of the certificate or certificates representing
the Series B Subordinate Voting Preferred Shares being converted.

         (5)      Before any holder of Series B Subordinate Voting Preferred
Shares shall be entitled to convert the same into Class B Subordinate Voting
Shares or Series A Non-Voting Preferred Shares such holder shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Company or of any transfer agent for the Series B Subordinate Voting Preferred
Shares, together with a written notice to the Company stating therein: the name
or names in which the certificate or certificates for Common Shares or Preferred
Shares are to be issued; the number of Series B Subordinate Voting Preferred
Shares to be converted; and notice of such holder's election to convert such
Series B Subordinate Voting Preferred Shares. After giving notice in writing,
the election of the holder of Series B Subordinate Voting Preferred Shares shall
be irrevocable although may be subject to the condition described below when the
conversion is in connection with an underwritten public offering. The Company
shall, within three (3) days of such written notice, issue and deliver at such
office to such holder of Series B Subordinate Voting Preferred Shares, or to the
nominee or nominees of such holder, a certificate or certificates for the number
of Class B Subordinate Voting Shares or Series A Non-Voting

<PAGE>
                                     - 30 -


Preferred Shares, as the case may be, to which such holder shall be entitled as
aforesaid. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the Series B
Subordinate Voting Preferred Shares to be converted, and the person or persons
entitled to receive the shares of Class B Subordinate Voting Shares or Series A
Non-Voting Preferred Shares, as the case may be, issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such Class
B Subordinate Voting Shares or Series A Non-Voting Preferred Shares, as the case
may be, as of such date. If the conversion is in connection with an underwritten
public offering of securities (other than a Qualified IPO), the conversion into
Common Shares may, at the option of any holder tendering Series B Subordinate
Voting Preferred Shares for conversion, be conditioned upon the closing with the
underwriters of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive the Common Shares upon conversion of the
Series B Subordinate Voting Preferred Shares shall not be deemed to have
converted such Series B Subordinate Voting Preferred Shares until immediately
prior to the closing of such sale of securities. The issuance of certificates
for Class B Subordinate Voting Shares or Series A Non-Voting Preferred Shares,
as the case may be, upon conversion of the Series B Subordinate Voting Preferred
Shares shall be made without charge to the holder thereof for any issuance tax
in respect thereof, provided that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of any certificate in a name other than that of the holder of the
Series B Subordinate Voting Preferred Shares which is being converted.

         (6)      The Company shall at no time close its transfer books against
the transfer of any Series B Subordinate Voting Preferred Shares, or of any
Class B Subordinate Voting Shares or Series A Non-Voting Preferred Shares
issuable upon the conversion of any Series B Subordinate Voting Preferred
Shares, in any manner which interferes with the timely conversion of such Series
B Subordinate Voting Preferred Shares, except as may otherwise be required to
comply with applicable laws or the provisions of the Attachment for these
Articles.

         (7)      As used in this Section 1.6 the term "Class B Subordinate
Voting Shares" shall mean and include the Company's issued Class B Subordinate
Voting Shares as constituted on the Initial Issue Date, and shall also include
any shares of any class of the capital of the Company thereafter authorized
which shall neither be limited to a fixed sum or percentage in respect of the
rights of the holders thereof to participate in dividends nor be entitled to a
preference in the distribution of assets upon the voluntary or involuntary
liquidation, dissolution or winding up of the Company provided that the Class B
Subordinate Voting Shares receivable upon conversion of Series B Subordinate
Voting Preferred Shares shall include only shares designated as Class B
Subordinate Voting Shares of the Company on the Initial Issue Date, or in case
of any reorganization or reclassification of the outstanding shares thereof, the
shares, securities or assets to be issued in exchange for such Class B
Subordinate Voting Shares pursuant thereto.

         (8)      If the Company shall be a party to any transaction including
without limitation, an amalgamation, arrangement, consolidation, sale of all or
substantially all of the Company's assets or a reorganization, reclassification
or recapitalization of the capital of the Company but excluding any transaction
for which provision for adjustment is otherwise made in this Section 1.6 (each
of the foregoing being referred to as a "Transaction"), in each case, as a
result of which Class B Subordinate Voting Shares are converted into the right
to receive shares, securities or other property (including, without limitation,
cash or any combination thereof), each Series B Subordinate Voting Preferred
Share shall thereafter be convertible into the number of

<PAGE>
                                     - 31 -


shares or other securities or property to which a holder of the number of Class
B Subordinate Voting Shares of the Company deliverable upon conversion of such
Series B Subordinate Voting Preferred Shares would have been entitled upon such
Transaction; and, in any such case, appropriate adjustment (as determined by the
Board of Directors) shall be made in the application of the provisions set forth
in this Section 1.6 with respect to the rights and interest thereafter of the
holders of the Series B Subordinate Voting Preferred Shares, to the end that the
provisions set forth in this Section 1.6 shall thereafter be applicable, as
nearly as reasonably may be, in relation to any shares or other property
thereafter deliverable upon the conversion of the Series B Subordinate Voting
Preferred Shares. The Company shall not effect any Transaction unless prior to
or simultaneously with the consummation thereof the Company or purchaser, as the
case may be, shall provide in its charter document that each Series B
Subordinate Voting Preferred Share shall be converted into such shares,
securities or property as, in accordance with the foregoing provisions, each
such holder is entitled to receive. The provisions of this Section 1.6(8) shall
similarly apply to successive Transactions.

         (9)      No fractional shares shall be issued upon the conversion of
any share or shares of the Series B Subordinate Voting Preferred Shares, and the
number of Common Shares to be issued shall be rounded down to the nearest whole
share. Whether or not fractional shares are issuable upon such conversion shall
be determined on the basis of the total number of shares of Series B Subordinate
Voting Preferred Shares the holder is at the time converting into Common Shares
or Series A Non-Voting Preferred Shares and the number of Common Shares or
Series A Non-Voting Preferred Shares issuable upon such aggregate conversion.

         (10)     If an event not specified in this Section 1.6 occurs that has
substantially the same economic effect on the Series B Subordinate Voting
Preferred Shares as those specifically enumerated above in this Section 1.6,
then this Section 1.6 shall be construed liberally, mutatis mutandis, in order
to give the holders of Series B Subordinate Voting Preferred Shares the intended
benefit of the protections provided under this Section 1.6. In such event, the
Company's Board of Directors shall make an appropriate adjustment in the
Conversion Ratio so as to protect the rights of the holders of Series B
Subordinate Voting Preferred Shares; provided that no such adjustment shall
increase or decrease the Conversion Ratio as otherwise determined pursuant to
this Section 1.6 or decrease the number of Class B Subordinate Voting Shares
issuable upon conversion of each Series B Subordinate Voting Preferred Share.

         (11)     The Company will not, by amendment of its Articles or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Company, and will at all times in good faith assist
in the carrying out of all the provisions of this Section 1.6 and in the taking
of all such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of the Series B Subordinate Voting Preferred
Shares against impairment.

         (12)     All calculations under this Section 1.6 shall be made to (a)
the nearest cent or (b) the nearest one hundredth of a share or (c) the nearest
one percent, as the case may be.

1.7               NOTICE OF CERTAIN EVENTS

                  In case, at any time while any Series B Subordinate Voting
Preferred Shares are outstanding,

         (1)      the Company shall declare a dividend (or any other
distribution) on its Common Shares;

         (2)      the Company shall authorize the issuance to the holders of its
Common Shares, of Common Share Equivalents, or rights or warrants to subscribe
for or purchase Common Shares or of any other subscriptions rights or warrants;

         (3)      the Company shall authorize any reorganization,
reclassification or recapitalization of its Common Shares;

         (4)      the Company shall authorize the consolidation or merger of the
Company into or with any other person, the sale or transfer of all or
substantially all of its business or assets to another person, or any other
similar business combination or transaction; or

         (5)      the Company shall authorize the voluntary or involuntary
dissolution, liquidation or winding up on the Company;

then the Company shall promptly deliver to the transfer agent of the Series B
Subordinate Voting Preferred Shares, if any, and to each of the holders of
Series B Subordinate Voting Preferred Shares at their last addresses as they
shall appear on the register for the Series B Subordinate Voting Preferred
Shares, at least 15 days before the date hereafter specified (or the earlier of
the dates hereinafter specified, in the event that more than one date is
specified), a notice describing such event and stating (A) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Shares of record to be entitled to such dividend, distribution, rights
or warrants are to be determined, or (B) the date on which any such
reclassification, reorganization, recapitalization, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Shares
of record shall be entitled to exchange their Common Shares for securities or
other property (including cash), if any, deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

1.8               REPORTS AS TO ADJUSTMENT

                  Upon any adjustment of the Conversion Ratio then in effect
pursuant to the provisions of Section 1.6 of this Article D then, and in each
such case, the Company shall promptly deliver to each of the holders of the
Series B Subordinate Voting Preferred Shares, a certificate signed by an officer
of the Company setting forth in reasonable detail the event requiring the
adjustment, the method by which such adjustment was calculated and the
Conversion Ratio then in effect following such Adjustment. Where appropriate,
such notice to holders of the Series B Subordinate Voting Preferred Shares may
be given in advance.

1.9               MANDATORY REDEMPTION

                  On November 2, 2009 (the "Redemption Date"), the Company shall
redeem all the Series B Subordinate Voting Preferred Shares then outstanding and
not theretofore surrendered for conversion, as follows: Thirty days prior to the
Redemption Date, the Company shall give written notice to all holders of Series
B Subordinate Voting Preferred Shares which shall specify the Redemption Date.
For each Series B Subordinate Voting Preferred Share which is to be redeemed,
the Company shall be obligated on the Redemption Date to pay and deliver share
certificates to the holder thereof (upon surrender by such holder at the
Company's principal executive office of the certificate representing such share
or an Affidavit of Loss with respect thereto) (a) an amount in immediately
available funds equal to the Series B Subordinate Voting Liquidation Value, and
(b) such number of Class B Subordinate Voting Shares as have an aggregate Market
Price (as determined on the day immediately before the Redemption Date) equal to
the excess of the Market Price (as determined on the day immediately before the
Redemption Date) of the Series B Subordinate Voting Preferred Share over the
Series A Non-Voting Liquidation Value. All Class B Subordinate Voting Shares
shall, when issued as contemplated herein, be validly issued, fully paid and
non-assessable. If the funds of the Company legally available for redemption of
the Series B Subordinate Voting Preferred Shares on the Redemption Date are
insufficient to redeem the total number of such shares to be redeemed on such
date, then those funds which are legally available shall be used to redeem the
maximum possible number of such shares ratably among the holders thereof, based
upon the aggregate Series B Subordinate Voting Liquidation Value of such Series
B Subordinate Voting Preferred Shares held by each such holder. At any time
thereafter when additional funds of the Company are legally available for the
redemption of Series B Subordinate Voting Preferred Shares, such funds shall
immediately be used to redeem on a similar ratable basis the balance of such
shares. Notwithstanding the foregoing, each holder of Series B Subordinate
Voting Preferred Shares shall be entitled to convert all or any portion of such
holder's shares pursuant to Section 1.6 of this Article D prior to the
Redemption Date and thereafter until such Series B Subordinate Voting Preferred
Shares are redeemed.

1.10              RESERVATION OF SHARES ISSUABLE UPON CONVERSION

                  The Company shall at all times reserve and keep available out
of its authorized but unissued Class B Subordinate Voting Shares and out of its
authorized but unissued Preferred Shares solely for the purpose of effecting the
conversion of the issued or issuable Series B Subordinate Voting Preferred
Shares, such number of its Class B Subordinate Voting Shares and Series A
Non-Voting Preferred Shares, as the case may be, as shall from time to time be
sufficient to effect the conversion of all outstanding Series B Subordinate
Voting Preferred Shares, and if at any time the number of authorized but
unissued Class B Subordinate Voting Shares or Series A Non-Voting Preferred
Shares shall not be sufficient to effect the conversion of all then outstanding
Series B Subordinate Voting Preferred Shares, the Company will take all such
corporate action as may be necessary to increase its authorized but unissued
Class B Subordinate Voting Shares or Series A Non-Voting Preferred Shares to
such number of shares as shall be sufficient for such purpose. All Class B
Subordinate Voting Shares and Series A Non-Voting Preferred Shares shall, when
issued upon conversion as contemplated herein, be validly issued, fully paid and
non-assessable.

which any Common Shares may at any time be listed, subject to official notice of
issuance upon the conversion of the Series B Subordinate Voting Preferred
Shares, all Class B Subordinate Voting Shares from time to time issuable upon
the conversion of Series B Subordinate Voting Preferred Shares and will maintain
such listing as long as any Class B Subordinate Voting Shares are listed.

1.12              CERTAIN COVENANTS

                  Any registered holder of Series B Subordinate Voting Preferred

                  "Junior Shares" shall mean any of the Company's Common Shares
and all other Capital Securities of the Company (other than the Series B
Subordinate Voting Preferred Shares and the Series A Non-Voting Preferred
Shares, which shall rank equally with the Series B Subordinate Voting Preferred
Shares).

                  "Market Price" of any security with a Minimum Float means the
average of the closing prices of such security's sales on all securities
exchanges on which such security may at the time be listed, or, if there have
been no sales on any such exchange on any day, the average of the highest bid
and lowest asked prices on all such exchanges at the end of such day, or, if on
any day such security is not so listed, the average of the representative bid
and asked prices quoted in the NASDAQ System as of 4:00 P.M., New York time, or,
if on any day such security is not quoted in the NASDAQ System, the average of
the highest bid and lowest asked prices on such day in the domestic
over-the-counter market as reported by the National Quotation Bureau,
Incorporated, or any similar successor organization, in each such case averaged
over a period of 21 days consisting of the day as of which "Market Price" is
being determined and the 20 consecutive Business Days prior to such day. If
there is not a Minimum Float with respect to the Series B Subordinate Voting
Preferred Shares, then the Market Price of a Series B Subordinate Voting
Preferred Share shall be determined as equal to the Market Price of a Common
Share times the number of Common Shares into which the Series B Subordinate
Voting Preferred Share is convertible as of the date of determination of the
Market Price. If at any time such security does not have a Minimum Float or is
not listed on any securities exchange or quoted in the NASDAQ System or the
over-the-counter market, the "Market Price" shall be the fair value thereof
determined jointly by the Company and the holders of a majority of the Series B
Subordinate Voting Preferred Shares. If such parties are unable to reach
agreement within a reasonable period of time, such fair value shall be
determined by an independent appraiser experienced in valuing securities jointly
selected by the Company and the holders of a majority of the Series B
Subordinate Voting Preferred Shares. If the Company and the holders of a
majority of the Series B Subordinate Voting Preferred Shares are unable to agree
on the selection of an independent appraiser within 30 days of the date when the
holders of a majority of the Series B Subordinate Voting Preferred Shares have
first delivered notice in writing to the Company of the name of a proposed
independent appraiser, then the holders of a majority of the Series B
Subordinate Voting Preferred Shares may request the President of the American
Arbitration Association to appoint an independent appraiser and such appointment
shall be final and binding for purposes of determination of the Market Price in
question. The determination of such appraiser shall be final and binding upon
the parties, and the Company shall pay the fees and expenses of such appraiser.

                  "Minimum Float" is achieved if the product of (i) the closing
price of a security listed on any securities exchange or quoted in the NASDAQ
system or the over-the-counter market multiplied by (ii) the number of shares or
units of such security registered pursuant to the United States Securities Act
of 1933, as then in effect, and held by the public is at least U.S.

         time determine shall be paid to the Company for every certificate other
         than the first certificate issued to any holder in respect of any share
         or shares.

16.      The directors may cause one or more branch Registers of shareholders to
         be kept in any place or places, whether inside or outside of Nova
         Scotia.


                               TRANSFER OF SHARES

17.      The instrument of transfer of any share in the Company shall be signed
         by the transferor. The transferor shall be deemed to remain the holder

         Register in respect thereof and shall be entitled to receive any
         dividend declared thereon before the registration of the transfer.

18.      The instrument of transfer of any share shall be in writing in the
         following form or to the following effect or in such other form as the
         directors may approve from time to time:

                  For value received, _____ hereby sell, assign, and transfer
                  unto ______, _____ shares in the capital of the Company
                  represented by the within certificate, and do hereby
                  irrevocably constitute and appoint _________ attorney to
                  transfer such shares on the books of the Company with full
                  power of substitution in the premises.

                  Dated the ____  day of ___________,

                  Witness:_____________________________

19.      Every instrument of transfer shall be left for registration at the
         Office of the Company, or at any office of its transfer agent where a
         Register is maintained, together with the certificate of the shares to
         be transferred and such other evidence as the Company may require to
         prove title to or the right to transfer the shares.

20.      The directors may require that a fee determined by them be paid before
         or after registration of any transfer.

21.      Every instrument of transfer shall, after its registration, remain in
         the custody of the Company. Any instrument of transfer that the
         directors decline to register shall, except in case of fraud, be
         returned to the person who deposited it.


                             TRANSMISSION OF SHARES


22.      The executors or administrators of a deceased shareholder (not being
         one of several joint holders) shall be the only persons recognized by
         the Company as having any title to the shares registered in the name of
         such shareholder. When a share is registered in the names of two or
         more joint holders, the survivor or survivors and the executors or
         administrators of the deceased shareholder, shall be the only persons
         recognized by the Company as having any title to, or interest in, such
         share.

23.      Notwithstanding anything in these Articles, if the Company has only one
         shareholder (not being one of several joint holders) and that
         shareholder dies, the executors or administrators of the deceased
         shareholder shall be entitled to register themselves in the Register as
         the holders of the shares registered in the name of the deceased
         shareholder whereupon they shall have all the rights given by these
         Articles and by law to shareholders.

24.      Any person entitled to shares upon the death or bankruptcy of any
         shareholder or in any way other than by allotment or transfer, upon
         producing such evidence of entitlement as the directors require, may be
         registered as a shareholder in respect of such shares, or may, without
         being registered, transfer such shares subject to the provisions of
         these Articles respecting the transfer of shares. The directors shall
         have the same right to refuse registration as if the transferee were
         named in an ordinary transfer presented for registration.

                               SURRENDER OF SHARES


25.      The directors may accept the surrender of any share by way of
         compromise of any question as to the holder being properly registered
         in respect thereof. Any share so surrendered may be disposed of in the
         same manner as a forfeited share.


                                  SHARE WARRANT


26.      The Company, with respect to any fully paid-up shares, may issue
         warrants ("Share Warrants") stating that the bearer is entitled to the
         shares therein specified, and may provide, by coupons or otherwise, for
         the payment of future dividends on the shares included in the Share
         Warrants.

27.      The directors may determine and vary the conditions upon which Share
         Warrants will be issued and, without limiting the generality of the
         foregoing, may determine the conditions upon which

         (1)      a new Share Warrant or coupon will be issued in the place of
                  one worn out, defaced, lost or destroyed, or

         (2)      the bearer of a Share Warrant will be entitled to attend and
                  vote at general meetings, or

         (3)      a Share Warrant may be surrendered and the name of the bearer
                  entered in the Register in respect of the shares therein
                  specified.

         Subject to such conditions and to these Articles the bearer of a Share
         Warrant shall be a shareholder to the full extent. The bearer of a
         Share Warrant shall be subject to the conditions for the time being in
         force, whether made before or after the issue of the Share Warrant.


                        INCREASE AND REDUCTION OF CAPITAL

28.      Subject to the Act, the Company may by resolution of its shareholders
         increase its share capital by the creation of new shares of such amount
         as it thinks expedient.\

29.      Subject to the Act, the new shares may be issued upon such terms and
         conditions and with such rights, privileges, limitations, restrictions
         and conditions attached thereto as the Company by resolution of its
         shareholders determines or, if no direction is given, as the directors
         determine.

30.      Except as otherwise provided by the conditions of issue, or by these
         Articles, any capital raised by the creation of new shares shall be
         considered part of the original capital and shall be subject to the
         provisions herein contained with reference to transfer and
         transmission, and otherwise.

31.      The Company may, by special resolution where required, reduce its share
         capital in any way and with and subject to any incident authorized and
         consent required by law.

                              ALTERATION OF CAPITAL

31.      Subject to the Act, the Company may by resolution of its shareholders:

         (1)      consolidate and divide all or any of its share capital into
                  shares of larger amount than its existing shares;

         (2)      convert all or any of its paid-up shares into stock and
                  reconvert that stock into paid-up shares of any denomination;

         (3)      exchange shares of one denomination for another; or

         (4)      cancel shares which, at the date of the passing of the
                  resolution in that behalf, have not been taken or agreed to be
                  taken by any person, and diminish the amount of its share
                  capital by the amount of the shares so cancelled.

33.      Subject to the Act, the Company may by special resolution:

         (1)      subdivide its shares, or any of them, into shares of smaller
                  amount than is fixed by the Memorandum, so, however, that in
                  the subdivision the proportion between the amount paid and the
                  amount, if any, unpaid on each reduced share shall be the same
                  as it was in the case of the share from which the reduced
                  share is derived and the special resolution whereby any share
                  is subdivided may determine that as between the holders of the
                  shares resulting from such subdivision, one or more of such
                  shares shall have some preference or special advantage as
                  regards dividend, capital, voting or otherwise, over, or as
                  compared with, the others or other;

         (2)      convert any part of its issued or unissued share capital into
                  preference shares redeemable or purchasable by the Company;

         (3)      provide for the issue of shares without any nominal or par
                  value provided that, upon any such issue, a declaration
                  executed by the Secretary must be filed with the Registrar
                  stating the number of shares issued and the amount received
                  therefor;

         (4)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares, other than preferred shares,
                  with nominal or par value into the same number of shares
                  without any nominal or par value, and reduce, maintain or
                  increase accordingly its liability on any of its shares so
                  converted; provided that the power to reduce its liability on
                  any of its shares so converted may, where it results in a
                  reduction of capital, only be exercised subject to
                  confirmation by the court as provided by the Act; or

         (5)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares without nominal or par value into
                  the same or a different number of shares with nominal or par
                  value, and for such purpose the shares issued without nominal
                  or par value and replaced by shares with a nominal or par
                  value shall be considered as fully paid, but their aggregate
                  par value shall not exceed the value of the net assets of the
                  Company as represented by the shares without par value issued
                  before the conversion.

34.      Subject to the Act and any provisions attached to such shares, the
         Company may redeem, purchase or acquire any of its shares and the
         directors may determine the manner and the terms for redeeming,
         purchasing or acquiring such shares and may provide a sinking fund on
         such terms as they think fit for the redemption, purchase or
         acquisition of shares of any class or series.


                            INTEREST ON SHARE CAPITAL

35.      The Company may pay interest at a rate not exceeding 6% per year on
         share capital issued and paid-up for the purpose of raising funds to
         defray the expenses of the construction of any works or buildings or
         the provision of any plant which cannot be operated profitably for a
         lengthy period of time. Such interest may be paid for such period and
         may be charged to capital as part of the cost of construction of the
         work or building or of the provision of the plant. The payment of the
         interest shall not operate to reduce the amount paid-up on the shares
         in respect of which it is paid. The accounts of the Company shall show
         full particulars of the payment during the period to which the accounts
         relate.


                          CLASSES AND SERIES OF SHARES

36.      Subject to the Act and the Memorandum, and without prejudice to any
         special rights previously conferred on the holders of existing shares,
         any share may be issued with such preferred, deferred or other special
         rights, or with such restrictions, whether in regard to dividends,
         voting, return of share capital or otherwise, as the Company may from
         time to time determine by special resolution.


                     MEETINGS AND VOTING BY CLASS OR SERIES

37.      Where the holders of shares of a class or series have, under the Act,
         the Memorandum, the terms or conditions attaching to such shares or
         otherwise, the right to vote separately as a class in respect of any
         matter then, except as provided in the Act, the Memorandum, these
         Articles or such terms or conditions, all the provisions in these
         Articles concerning general meetings (including, without limitation,
         provisions respecting notice, quorum and procedure) shall, mutatis
         mutandis, apply to every meeting of holders of such class or series of
         shares convened for the purpose of such vote.

38.      Unless the rights, privileges, terms or conditions attached to a class
         or series of shares provided otherwise, such class or series of shares
         shall not have the right to vote separately as a class or series upon
         an amendment to the Memorandum or Articles to:

         (1)      increase or decrease any maximum number of authorized shares
                  of such class or series, or increase any maximum number of
                  authorized shares of a class or series having rights or
                  privileges equal or superior to the shares of such class or
                  series;

         (2)      effect an exchange, reclassification or cancellation of all or
                  part of the shares of such class or series; or

<PAGE>
                                     - 8 -


         (3)      create a new class or series of shares equal or superior to
                  the shares of such class or series.


                                BORROWING POWERS

39.      The directors on behalf of the Company may:

         (1)      raise or borrow money for the purposes of the Company or any
                  of them;

         (2)      secure, subject to the sanction of a special resolution where
                  required by the Act, the repayment of funds so raised or
                  borrowed in such manner and upon such terms and conditions in
                  all respects as they think fit, and in particular by the
                  execution and delivery of mortgages of the Company's real or
                  personal property, or by the issue of bonds, debentures or
                  other securities of the Company secured by mortgage or other
                  charge upon all or any part of the property of the Company,
                  both present and future;

         (3)      sign or endorse bills, notes, acceptances, cheques, contracts,
                  and other evidence of or securities for funds borrowed or to
                  be borrowed for the purposes aforesaid;

         (4)      pledge debentures as security for loans;

         (5)      guarantee obligations of any person.

40.      Bonds, debentures and other securities may be made assignable, free
         from any equities between the Company and the person to whom such
         securities were issued.

41.      Any bonds, debentures and other securities may be issued at a discount,
         premium or otherwise and with special privileges as to redemption,
         surrender, drawings, allotment of shares, attending and voting at
         general meetings of the Company, appointment of directors and other
         matters.


                                GENERAL MEETINGS

42.      Ordinary general meetings of the Company shall be held at least once in
         every calendar year at such time and place as may be determined by the
         directors and not later than 15 months after the preceding ordinary
         general meeting. All other meetings of the Company shall be called
         special general meetings. Ordinary or special general meetings may be
         held either within or without the Province of Nova Scotia.

43.      The Chair, President, Chief Financial Officer or the directors may at
         any time convene a special general meeting, and the directors, upon the
         requisition of shareholders in accordance with the Act shall forthwith
         proceed to convene such meeting or meetings to be held at such time and
         place or times and places as the directors determine.

44.      The requisition shall state the objects of the meeting requested, be
         signed by the requisitionists and deposited at the Office of the
         Company. It may consist of several documents in like form each signed
         by one or more of the requisitionists.

                                     - 9 -


45.      At least seven clear days' notice, or such longer period of notice as
         may be required by the Act, of every general meeting, specifying the
         place, day and hour of the meeting and, when special business is to be
         considered, the general nature of such business, shall be given to the
         shareholders entitled to be present at such meeting by notice given as
         permitted by these Articles. With the consent in writing of all the
         shareholders entitled to vote at such meeting, a meeting may be
         convened by a shorter notice and in any manner they think fit, or
         notice of the time, place and purpose of the meeting may be waived by
         all of the shareholders.

46.      When it is proposed to pass a special resolution, the two meetings may
         be convened by the same notice, and it shall be no objection to such
         notice that it only convenes the second meeting contingently upon the
         resolution being passed by the requisite majority at the first meeting.

47.      The accidental omission to give notice to a shareholder, or non-receipt
         of notice by a shareholder, shall not invalidate any resolution passed
         at any general meeting.


                                  RECORD DATES

48.      (1)      The directors may fix in advance a date as the record date for
                  the determination of shareholders

         (a)      entitled to receive payment of a dividend or entitled to
                  receive any distribution;

         (b)      entitled to receive notice of a meeting; or

         (c)      for any other purpose.

         (2)      If no record date is fixed, the record date for the
                  determination of shareholders

         (a)      entitled to receive notice of a meeting shall be the day
                  immediately preceding the day on which the notice is given,
                  or, if no notice is given, the day on which the meeting is
                  held; and

         (b)      for any other purpose shall be the day on which the directors
                  pass the resolution relating to the particular purpose.


                         PROCEEDINGS AT GENERAL MEETINGS

49.      The business of an ordinary general meeting shall be to receive and
         consider the financial statements of the Company and the report of the
         directors and the report, if any, of the auditors, to elect directors
         in the place of those retiring, to appoint the auditors of the Company
         for the ensuing fiscal year and to transact any other business which
         under these Articles ought to be transacted at an ordinary general
         meeting.

50.      No business shall be transacted at any general meeting unless the
         requisite quorum is present at the commencement of the business. A
         corporate shareholder of the Company that has a duly authorized agent
         or representative present at any such meeting shall for the purpose of
         this Article be deemed to be personally present at such meeting.

51.      One person, being a shareholder, proxyholder or representative of a
         corporate shareholder, present and entitled to vote shall constitute a
         quorum for a general meeting, and may hold a meeting.

52.      The Chair shall be entitled to take the chair at every general meeting
         or, if there be no Chair, or if the Chair is not present within fifteen
         15 minutes after the time appointed for holding the meeting, the
         President or, failing the President, a vice-president shall be entitled
         to take the chair. If the Chair, the President or a vice-president is
         not present within 15 minutes after the time appointed for holding the
         meeting or if all such persons present decline to take the chair, the
         shareholders present entitled to vote at the meeting shall choose
         another director as chair and if no director is present or if all the
         directors present decline to take the chair, then such shareholders
         shall choose one of their number to be chair.

53.      If within half an hour from the time appointed for a general meeting a
         quorum is not present, the meeting, if it was convened pursuant to a
         requisition of shareholders, shall be dissolved. If it was convened in
         any other way, it shall stand adjourned to the same day, in the next
         week, at the same time and place. If at the adjourned meeting a quorum
         is not present within half an hour from the time appointed for the
         meeting, the shareholders present shall be a quorum and may hold the
         meeting.

54.      Subject to the Act, at any general meeting a resolution put to the
         meeting shall be decided by a show of hands unless, either before or on
         the declaration of the result of the show of hands, a poll is demanded
         by the chair, a shareholder or a proxyholder; and unless a poll is so
         demanded, a declaration by the chair that the resolution has been
         carried, carried by a particular majority, lost or not carried by a
         particular majority and an entry to that effect in the Company's book
         of proceedings shall be conclusive evidence of the fact without proof
         of the number or proportion of the votes recorded in favour or against
         such resolution.

55.      When a poll is demanded, it shall be taken in such manner and at such
         time and place as the chair directs, and either at once or after an
         interval or adjournment or otherwise. The result of the poll shall be
         the resolution of the meeting at which the poll was demanded. The
         demand of a poll may be withdrawn. When any dispute occurs over the
         admission or rejection of a vote, it shall be resolved by the chair and
         such determination made in good faith shall be final and conclusive.

56.      The chair shall not have a casting vote in addition to any vote or
         votes that the chair has as a shareholder.

57.      The chair of a general meeting may with the consent of the meeting
         adjourn the meeting from time to time and from place to place, but no
         business shall be transacted at any adjourned meeting other than the
         business left unfinished at the meeting that was adjourned.

58.      Any poll demanded on the election of a chair or on a question of
         adjournment shall be taken forthwith without adjournment.

59.      The demand of a poll shall not prevent the continuance of a meeting for
         the transaction of any business other than the question on which a poll
         has been demanded.

                             VOTES OF SHAREHOLDERS

60.      Subject to the Act and to any provisions attached to any class or
         series of shares concerning voting rights

         (1)      on a show of hands every shareholder present in person, every
                  duly authorized representative of a corporate shareholder,
                  and, if not prevented from voting by the Act, every
                  proxyholder, shall have one vote; and

         (2)      on a poll every shareholder present in person, every duly
                  authorized representative of a corporate shareholder, and
                  every proxyholder, shall have one vote for every share held;

         whether or not such representative or proxyholder is a shareholder.

61.      Any person entitled to transfer shares upon the death or bankruptcy of
         any shareholder or in any way other than by allotment or transfer may
         vote at any general meeting in respect thereof in the same manner as if
         such person were the registered holder of such shares so long as the
         directors are satisfied at least 48 hours before the time of holding
         the meeting of such person's right to transfer such shares.

62.      Where there are joint registered holders of any share, any of such
         holders may vote such share at any meeting, either personally or by
         proxy, as if solely entitled to it. If more than one joint holder is
         present at any meeting, personally or by proxy, the one whose name
         stands first on the Register in respect of such share shall alone be
         entitled to vote it. Several executors or administrators of a deceased
         shareholder in whose name any share stands shall for the purpose of
         this Article be deemed joint holders thereof.

63.      Votes may be cast either personally or by proxy or, in the case of a
         corporate shareholder by a representative duly authorized under the
         Act.

64.      A proxy shall be in writing and executed in the manner provided in the
         Act. A proxy or other authority of a corporate shareholder does not
         require its seal. Holders of Share Warrants shall not be entitled to
         vote by proxy in respect of the shares included in such warrants unless
         otherwise expressed in such warrants.

65.      A shareholder of unsound mind in respect of whom an order has been made
         by any court of competent jurisdiction may vote by guardian or other
         person in the nature of a guardian appointed by that court, and any
         such guardian or other person may vote by proxy.

66.      A proxy and the power of attorney or other authority, if any, under
         which it is signed or a notarially certified copy of that power or
         authority shall be deposited at the Office of the Company or at such
         other place as the directors may direct. The directors may, by
         resolution, fix a time not exceeding 72 hours excluding Saturdays and
         holidays preceding any meeting or adjourned meeting before which time
         proxies to be used at that meeting must be deposited with the Company
         at its Office or with an agent of the Company. Notice of the
         requirement for depositing proxies shall be given in the notice calling
         the meeting. The chair of the meeting shall determine all questions as
         to validity of proxies and other instruments of authority.

                                     - 12 -


67.      A vote given in accordance with the terms of a proxy shall be valid
         notwithstanding the previous death of the principal, the revocation of
         the proxy, or the transfer of the share in respect of which the vote is
         given, provided no intimation in writing of the death, revocation or
         transfer is received at the Office of the Company before the meeting or
         by the chair of the meeting before the vote is given.

68.      Every form of proxy shall comply with the Act and its regulations and
         subject thereto may be in the following form:

                  I, _________ of ____________ being a shareholder of _____
                  hereby appoint _______ of ________ (or failing him/her _____
                  of _____) as my proxyholder to attend and to vote for me and
                  on my behalf at the ordinary/special general meeting of the
                  Company, to be held on the ___ day of ____ and at any
                  adjournment thereof, or at any meeting of the Company which
                  may be held prior to [insert specified date or event].

                  [If the proxy is solicited by or behalf of the management of
                  the Company, insert a statement to that effect.]

                  Dated this ____ day of __________ ____.


                           Shareholder

69.      Any resolution passed by the directors, notice of which has been given
         to the shareholders in the manner in which notices are hereinafter
         directed to be given and which is, within one month after it has been
         passed, ratified and confirmed in writing by shareholders entitled on a
         poll to three-fifths of the votes, shall be as valid and effectual as a
         resolution of a general meeting. This Article shall not apply to a
         resolution for winding up the Company or to a resolution dealing with
         any matter that by statute or these Articles ought to be dealt with by
         a special resolution or other method prescribed by statute.

70.      A resolution, including a special resolution, in writing and signed by
         every shareholder who would be entitled to vote on the resolution at a
         meeting is as valid as if it were passed by such shareholders at a
         meeting and satisfies all of the requirements of the Act respecting
         meetings of shareholders.


                                    DIRECTORS

71.      Unless otherwise determined by resolution of shareholders, the number
         of directors shall not be less than one or more than seventeen.

72.      Notwithstanding anything herein contained the directors of the Company
         on the date of its continuance shall continue to be the directors of
         the Company until their successors are appointed or they otherwise
         cease to be directors in accordance with these Articles.

73.      Subject to applicable law, the directors may be paid out of the funds
         or the capital of the Company as remuneration for their service such
         sums, shares or options, if any, as

<PAGE>
                                     - 13 -


         the directors may determine, and such remuneration shall be divided
         among them in such proportions and manner as the directors determine.
         The directors may also be paid their reasonable travelling, hotel and
         other expenses incurred in attending meetings of directors and
         otherwise in the execution of their duties as directors.

74.      The continuing directors may act notwithstanding any vacancy in their
         body, but if their number falls below the minimum permitted, the
         directors shall not, except in emergencies or for the purpose of
         filling vacancies, act so long as their number is below the minimum.


75.

         A director may, in conjunction with the office of director, and on such
         terms as to remuneration and otherwise as the directors arrange or
         determine, hold any other office or place of profit under the Company
         or under any company in which the Company is a shareholder or is
         otherwise interested.

76.      The office of a director shall ipso facto be vacated, if the director:

         (1)      becomes bankrupt or makes an assignment for the benefit of
                  creditors;

         (1)      is, or is found by a court of competent jurisdiction to be, of
                  unsound mind;

         (2)      by notice in writing to the Secretary at the Company's Office,
                  resigns the office of director; or

         (3)      is removed in the manner provided by these Articles.

77.      It shall be the duty of a director who is in any way, whether directly
         or indirectly, interested in a contract or proposed contract with the
         Company to declare the nature of such interest at a meeting of the
         directors of the Company. In the case of a proposed contract the
         declaration required to be made shall be made at a meeting of the
         directors at which the question of entering into the contract is first
         taken into consideration, or if the director was not at the date of
         that meeting interested in the proposed contract, at the next meeting
         of the directors held after the director became so interested, and in a
         case where the director becomes interested in a contract after it is
         made, the declaration shall be made at the first meeting of the
         directors held after the director becomes so interested. A general
         notice given to the directors of the Company by a director to the
         effect that such director is a member of a specified company or firm
         and is to be regarded as interested in any contract which may, after
         the date of the notice, be made with that company or firm shall be
         deemed to be a sufficient declaration of interest in relation to any
         contract so made.


                              ELECTION OF DIRECTORS

78.      At the dissolution of every ordinary general meeting at which their
         successors are elected, all the directors shall retire from office and
         be succeeded by the directors elected at such meeting. Retiring
         directors shall be eligible for re-election.

79.      If at any ordinary general meeting at which an election of directors
         ought to take place no such election takes place, or if no ordinary
         general meeting is held in any year or period of years, the retiring
         directors shall continue in office until their successors are elected.

                                     - 14 -


80.      The Company may by resolution of its shareholders elect any number of
         directors permitted by these Articles and may determine or alter their
         qualification.

81.      The Company may, by special resolution or in any other manner permitted
         by statute, remove any director before the expiration of such
         director's period of office and may, if desired, appoint a replacement
         to hold office during such time only as the director so removed would
         have held office.

82.      The directors may appoint any other person as a director so long as the
         total number of directors does not at any time exceed the maximum
         number permitted. No such appointment, except to fill a casual vacancy,
         shall be effective unless two-thirds of the directors concur in it. Any
         casual vacancy occurring among the directors may be filled by the
         directors, but any person so chosen shall retain office only so long as
         the vacating director would have retained it if the vacating director
         had continued as director.


                               CHAIR OF THE BOARD

83.      The directors may elect one of their number to be chair and may
         determine the period during which the chair is to hold office. The
         chair shall perform such duties and receive such special remuneration
         as the directors may provide.


             PRESIDENT, CHIEF EXECUTIVE OFFICER AND VICE-PRESIDENTS

84.      The directors shall appoint the President and Chief Executive Officer
         of the Company, who need not be a director, and may determine the
         period for which the President and Chief Executive Officer is to hold
         office. The President and Chief Executive Officer shall have general
         supervision of the business of the Company and shall perform such
         duties as may be assigned from time to time by the directors.

85.      The directors may also appoint vice-presidents, who need not be
         directors, and may determine the periods for which they are to hold
         office. A vice-president shall, at the request of the President or the
         directors and subject to the directions of the directors, perform the
         duties of the President during the absence, illness or incapacity of
         the President, and shall also perform such duties as may be assigned by
         the President or the directors.


                             SECRETARY AND TREASURER

86.      The directors shall appoint a Secretary of the Company to keep minutes
         of shareholders' and directors' meetings and perform such other duties
         as may be assigned by the directors. The directors may also appoint a
         temporary substitute for the Secretary who shall, for the purposes of
         these Articles, be deemed to be the Secretary.

87.      The directors may appoint a treasurer of the Company to carry out such
         duties as the directors may assign.

                                    OFFICERS

88.      The directors may elect or appoint such other officers of the Company,
         having such powers and duties, as they think fit.

89.      If the directors so decide the same person may hold more than one of
         the offices provided for in these Articles.

90.      Notwithstanding anything herein contained the officers of the Company
         on the date of its continuance shall continue to hold office until
         their successors are appointed or they otherwise cease to hold office
         in accordance with these Articles.


                            PROCEEDINGS OF DIRECTORS

91.      The directors may meet together for the dispatch of business, adjourn
         and otherwise regulate their meetings and proceedings, as they think
         fit. Until otherwise determined, a quorum for meetings of the board
         shall be the number of directors then in office, less three (3), of
         which three (3) shall be investor designees.

92.      If at a meeting of directors a quorum is not present, the directors may
         adjourn the meeting to a fixed time and place (provided they shall give
         written notice of such time and place to each director not in
         attendance). At the meeting immediately following the adjourned
         meeting, the directors present at such meeting shall constitute a
         quorum; provided however, that unless a full quorum is present as
         provided in section 91, the directors present at such meeting may not
         transact any business except as specifically set forth in the notice of
         meeting.

93.      A director may participate in a meeting of directors or of a committee
         of directors by means of such telephone or other communications
         facilities as permit all persons participating in the meeting to hear
         each other, and a director participating in such a meeting by such
         means is deemed to be present at that meeting for purposes of these
         Articles.

94.      Meetings of directors may be held either within or without the Province
         of Nova Scotia and the directors may from time to time make
         arrangements relating to the time and place of holding directors'
         meetings, the notices to be given for such meetings and what meetings
         may be held without notice. Unless otherwise provided by such
         arrangements:

         (1)      A meeting of directors may be held at the close of every
                  ordinary general meeting of the Company without notice.

         (2)      Notice of every other directors' meeting may be given as
                  permitted by these Articles to each director at least 48 hours
                  before the time fixed for the meeting.

         (3)      A meeting of directors may be held without formal notice if
                  all the directors are present or if those absent have
                  signified their assent to such meeting or their consent to the
                  business transacted at such meeting.

95.      The President or any director may at any time, and the Secretary, upon
         the request of the President or any director, shall summon a meeting of
         the directors to be held at the Office of

<PAGE>
                                     - 16 -


         the Company. The President, the Chair or a majority of the directors
         may at any time, and the Secretary, upon the request of the President,
         the Chair or a majority of the directors, shall summon a meeting to be
         held elsewhere.

96.      (1)      Questions arising at any meeting of directors shall be decided
                  by a majority of votes. The chair of the meeting may vote as a
                  director but shall not have a second or casting vote.

         (2)      At any meeting of directors the chair shall receive and count
                  the vote of any director not present in person at such meeting
                  on any question or matter arising at such meeting whenever
                  such absent director has indicated by telegram, letter or
                  other writing lodged with the chair of such meeting the manner
                  in which the absent director desires to vote on such question
                  or matter and such question or matter has been specifically
                  mentioned in the notice calling the meeting as a question or
                  matter to be discussed or decided thereat.

97.      If no Chair is elected, or if at any meeting of directors the Chair is
         not present within five minutes after the time appointed for holding
         the meeting, or declines to take the chair, the President, if a
         director, shall preside. If the President is not a director, is not
         present at such time or declines to take the chair, a vice-president
         who is also a director shall preside. If no person described above is
         present at such time and willing to take the chair, the directors
         present shall choose some one of their number to be chair of the
         meeting.

98.      A meeting of the directors at which a quorum is present shall be
         competent to exercise all or any of the authorities, powers and
         discretions for the time being vested in or exercisable by the
         directors generally.

99.      The directors may delegate any of their powers to committees consisting
         of such number of directors as they think fit. Any committee so formed
         shall in the exercise of the powers so delegated conform to any
         regulations that may be imposed on them by the directors.

100.     The meetings and proceedings of any committee of directors shall be
         governed by the provisions contained in these Articles for regulating
         the meetings and proceedings of the directors insofar as they are
         applicable and are not superseded by any regulations made by the
         directors.

101.     All acts done at any meeting of the directors or of a committee of
         directors or by any person acting as a director shall, notwithstanding
         that it is afterwards discovered that there was some defect in the
         appointment of the director or person so acting, or that they or any of
         them were disqualified, be as valid as if every such person had been
         duly appointed and was qualified to be a director.

102.     A resolution in writing and signed by every director who would be
         entitled to vote on the resolution at a meeting is as valid as if it
         were passed by such directors at a meeting.

103.     If any one or more of the directors is called upon to perform extra
         services or to make any special exertions in going or residing abroad
         or otherwise for any of the purposes of the Company or the business
         thereof, the Company may remunerate the director or directors so doing,
         either by a fixed sum or by a percentage of profits or otherwise. Such
         remuneration

<PAGE>
                                     - 17 -


         shall be determined by the directors and may be either in addition to
         or in substitution for remuneration otherwise authorized by these
         Articles.


                                    REGISTERS

104.     The directors shall cause to be kept at the Company's Office in
         accordance with the provisions of the Act a Register of the
         shareholders of the Company, a register of the holders of bonds,
         debentures and other securities of the Company and a register of its
         directors. Branch registers of the shareholders and of the holders of
         bonds, debentures and other securities may be kept elsewhere, either
         within or without the Province of Nova Scotia, in accordance with the
         Act.


                                     MINUTES

105.     The directors shall cause minutes to be entered in books designated for
         the purpose:

         (1)      of all appointments of officers;

         (2)      of the names of directors present at each meeting of directors
                  and of any committees of directors; and

         (3)      of all resolutions and proceedings of meetings of shareholders
                  and of directors.

         Any such minutes of any meeting of directors or of any committee of
         directors or of shareholders, if purporting to be signed by the chair
         of such meeting or by the chair of the next succeeding meeting, shall
         be receivable as prima facie evidence of the matters stated in such
         minutes.


                               POWERS OF DIRECTORS

106.     The management of the business of the Company is vested in the
         directors who, in addition to the powers and authorities by these
         Articles or otherwise expressly conferred upon them, may exercise all
         such powers and do all such acts and things as may be exercised or done
         by the Company and are not hereby or by statute expressly directed or
         required to be exercised or done by the shareholders, but subject
         nevertheless to the provisions of any statute, the Memorandum or these
         Articles. No modification of the Memorandum or these Articles shall
         invalidate any prior act of the directors that would have been valid if
         such modification had not been made.

107.     Without restricting the generality of the terms of any of these
         Articles and without prejudice to the powers conferred thereby, the
         directors may:

                  acquire, at such price and generally on such terms and
                  conditions as they think fit;

         (4)      pay for any property, rights or privileges acquired by, or

                  unpaid capital for the time being, or in such other manner as
                  they think fit;

         (6)      appoint, remove or suspend at their discretion such experts,
                  managers, secretaries, treasurers, officers, clerks, agents
                  and servants for permanent, temporary or special services, as
                  they from time to time think fit, and determine their powers
                  and duties and fix their salaries or emoluments and require
                  security in such instances and to such amounts as they think
                  fit;

         (7)      accept a surrender of shares from any shareholder insofar as
                  the law permits and on such terms and conditions as may be
                  agreed;

         (8)      appoint any person or persons to accept and hold in trust for
                  the Company any property belonging to the Company, or in which
                  it is interested, execute and do all such deeds and things as

                  transfers, hypothecations, pledges, endorsements, cheques,

                  instruments and documents;

         (13)     provide for the management of the affairs of the Company

                  such terms as may be thought fit;

         (14)     invest and deal with any funds of the Company in such
                  securities and in such manner as they think fit; and vary or
                  realize such investments;

                                     - 19 -



         (15)     subject to the Act, execute in the name and on behalf of the
                  Company in favour of any director or other person who may
                  incur or be about to incur any personal liability for the

                  property, present and future, as they think fit;

         (16)     give any officer or employee of the Company a commission on

         (17)     set aside out of the profits of the Company before declaring

                  depreciation, repairing, improving and maintaining any of the
                  property of the Company and such other purposes as the
                  directors may in their absolute discretion think in the
                  interests of the Company; and invest such amounts in such
                  investments as they think fit, and deal with and vary such

                  benefit of the Company, and divide the reserve fund into such
                  special funds as they think fit, with full power to employ the
                  assets constituting the reserve fund in the business of the
                  Company without being bound to keep them separate from the
                  other assets;

         (18)     make, vary and repeal rules respecting the business of the

                  such negotiations and contracts, rescind and vary all such
                  contracts, and execute and do all such acts, deeds and things
                  in the name and on behalf of the Company as they consider

                  or otherwise for the purposes of the Company; (48) provide for
                  the management of the affairs of the Company in such manner as
                  they think fit.


                                   SOLICITORS

108.     The Company may employ or retain solicitors any of whom may, at the
         request or on the instruction of the directors, the Chair, the
         President or a managing director, attend meetings of the directors or
         shareholders, whether or not the solicitor is a shareholder or a
         director of the Company. A solicitor who is also a director may
         nevertheless charge for services rendered to the Company as a
         solicitor.


                                    THE SEAL

109.     The directors shall arrange for the safe custody of the common seal of
         the Company (the "Seal"). The Seal may be affixed to any instrument in
         the presence of and contemporaneously with the attesting signature of
         (i) any director or officer acting within such person's authority or
         (ii) any person under the authority of a resolution of the directors or
         a committee thereof. For the purpose of certifying documents or
         proceedings the Seal may be affixed by any director or the President, a
         vice-president, the Secretary, an assistant secretary or any other
         officer of the Company without the authorization of a resolution of the
         directors.

<PAGE>
                                     - 20 -


110.     The Company may have facsimiles of the Seal which may be used
         interchangeably with the Seal.


                                    DIVIDENDS

111.     The directors may from time to time declare such dividend as they deem
         proper upon shares of the Company according to the rights and
         restrictions attached to any class or series of shares, and may
         determine the date upon which such dividend will be payable and that it
         will be payable to the persons registered as the holders of the shares
         on which it is declared at the close of business upon a record date. No
         transfer of such shares registered after the record date shall pass any
         right to the dividend so declared.

112.     No dividends shall be payable except out of the profits, retained
         earnings or contributed surplus of the Company and no interest shall be
         payable on any dividend except insofar as the rights attached to any
         class or series of shares provide otherwise.

113.     The declaration of the directors as to the amount of the profits,
         retained earnings or contributed surplus of the Company shall be
         conclusive.

114.     The directors may from time to time pay to the shareholders such
         interim dividends as in their judgment the position of the Company
         justifies.

115.     Subject to the Memorandum, these Articles and the rights and
         restrictions attached to any class or series of shares, dividends may
         be declared and paid to the shareholders in proportion to the amount of
         capital paid-up on the shares (not including any capital paid-up
         bearing interest) held by them respectively.

116.     The directors may deduct from the dividends payable to any shareholder
         amounts due and payable by the shareholder to the Company and may apply
         the same in or towards satisfaction of such amounts so due and payable.

117.     The directors may retain the dividends payable upon shares to which a
         person is entitled or entitled to transfer upon the death or bankruptcy
         of a shareholder or in any way other than by allotment or transfer,
         until such person has become registered as the holder of such shares or
         has duly transferred such shares.

118.     The directors may declare that a dividend be paid by the distribution
         of cash, paid-up shares (at par or at a premium), debentures, bonds or
         other securities of the Company or of any other company or any other
         specific assets held or to be acquired by the Company or in any one or
         more of such ways.

119.     The directors may settle any difficulty that may arise in regard to the
         distribution of a dividend as they think expedient, and in particular
         without restricting the generality of the foregoing may issue
         fractional certificates, may fix the value for distribution of any
         specific assets, may determine that cash payments will be made to any
         shareholders upon the footing of the value so fixed or that fractions
         may be disregarded in order to adjust the rights of all parties, and
         may vest cash or specific assets in trustees upon such trusts for the
         persons entitled to the dividend as may seem expedient to the
         directors.

<PAGE>
                                     - 21 -


120.     Any person registered as a joint holder of any share may give effectual
         receipts for all dividends and payments on account of dividends in
         respect of such share.

121.     Unless otherwise determined by the directors, any dividend may be paid
         by a cheque or warrant delivered to or sent through the post to the
         registered address of the shareholder entitled, or, when there are
         joint holders, to the registered address of that one whose name stands
         first on the register for the shares jointly held. Every cheque or
         warrant so delivered or sent shall be made payable to the order of the
         person to whom it is delivered or sent. The mailing or other
         transmission to a shareholder at the shareholder's registered address
         (or, in the case of joint shareholders at the address of the holder
         whose name stands first on the register) of a cheque payable to the
         order of the person to whom it is addressed for the amount of any
         dividend payable in cash after the deduction of any tax which the
         Company has properly withheld, shall discharge the Company's liability
         for the dividend unless the cheque is not paid on due presentation. If
         any cheque for a dividend payable in cash is not received, the Company
         shall issue to the shareholder a replacement cheque for the same amount
         on such terms as to indemnity and evidence of non-receipt as the
         directors may impose. No shareholder may recover by action or other
         legal process against the Company any dividend represented by a cheque
         that has not been duly presented to a banker of the Company for payment
         or that otherwise remains unclaimed for 6 years from the date on which
         it was payable.


                                    ACCOUNTS

122.     The directors shall cause proper books of account to be kept of the
         amounts received and expended by the Company, the matters in respect of
         which such receipts and expenditures take place, all sales and
         purchases of goods by the Company, and the assets, credits and
         liabilities of the Company.

123.     The books of account shall be kept at the head office of the Company or
         at such other place or places as the directors may direct.

124.     The directors shall from time to time determine whether and to what
         extent and at what times and places and under what conditions the
         accounts and books of the Company or any of them shall be open to
         inspection of the shareholders, and no shareholder shall have any right
         to inspect any account or book or document of the Company except as
         conferred by statute or authorized by the directors or a resolution of
         the shareholders.

125.     At the ordinary general meeting in every year the directors shall lay
         before the Company such financial statements and reports in connection
         therewith as may be required by the Act or other applicable statute or
         regulation thereunder and shall distribute copies thereof at such times
         and to such persons as may be required by statute or regulation.


                               AUDITORS AND AUDIT

126.     Except in respect of a financial year for which the Company is exempt
         from audit requirements in the Act, the Company shall at each ordinary
         general meeting appoint an auditor or auditors to hold office until the
         next ordinary general meeting. If at any general meeting at which the
         appointment of an auditor or auditors is to take place and no such

<PAGE>
                                     - 22 -


         appointment takes place, or if no ordinary general meeting is held in
         any year or period of years, the directors shall appoint an auditor or
         auditors to hold office until the next ordinary general meeting.

127.     The first auditors of the Company may be appointed by the directors at
         any time before the first ordinary general meeting and the auditors so
         appointed shall hold office until such meeting unless previously
         removed by a resolution of the shareholders, in which event the
         shareholders may appoint auditors.

128.     The directors may fill any casual vacancy in the office of the auditor
         but while any such vacancy continues the surviving or continuing
         auditor or auditors, if any, may act.

129.     The Company may appoint as auditor any person, including a shareholder,
         not disqualified by statute. 121. An auditor may be removed or replaced
         in the circumstances and in the manner specified in the Act. 122. The
         remuneration of the auditors shall be fixed by the shareholders, or by
         the directors pursuant to authorization given by the shareholders,
         except that the remuneration of an auditor appointed to fill a casual
         vacancy may be fixed by the directors. 123. The auditors shall conduct
         such audit as may be required by the Act and their report, if any,
         shall be dealt with by the Company as required by the Act.


                                     NOTICES

133.     A notice (including any communication or document) shall be
         sufficiently given, delivered or served by the Company upon a
         shareholder, director, officer or auditor by personal delivery at such
         person's registered address (or, in the case of a director, officer or
         auditor, last known address) or by prepaid mail, telegraph, telex,
         facsimile machine or other electronic means of communication addressed
         to such person at such address.

134.     Shareholders having no registered address shall not be entitled to
         receive notice.

135.     The holder of a share warrant shall not, unless otherwise expressed
         therein, be entitled in respect thereof to notice of any general
         meeting of the Company.

136.     All notices with respect to registered shares to which persons are
         jointly entitled may be sufficiently given to all joint holders thereof
         by notice given to whichever of such persons is named first in the
         Register for such shares.

137.     Any notice sent by mail shall be deemed to be given, delivered or
         served on the earlier of actual receipt and the third business day
         following that upon which it is mailed, and in proving such service it
         shall be sufficient to prove that the notice was properly addressed and
         mailed with the postage prepaid thereon. Any notice given by electronic
         means of communication shall be deemed to be given when entered into
         the appropriate transmitting device for transmission. A certificate in
         writing signed on behalf of the Company that the notice was so
         addressed and mailed or transmitted shall be conclusive evidence
         thereof.

<PAGE>
                                     - 23 -


138.     Every person who by operation of law, transfer or other means
         whatsoever becomes entitled to any share shall be bound by every notice
         in respect of such share that prior to such person's name and address
         being entered on the Register was duly served in the manner
         hereinbefore provided upon the person from whom such person derived
         title to such share.

139.     Any notice delivered, sent or transmitted to the registered address of
         any shareholder pursuant to these Articles, shall, notwithstanding that
         such shareholder is then deceased and that the Company has notice
         thereof, be deemed to have been served in respect of any registered
         shares, whether held by such deceased shareholder solely or jointly
         with other persons, until some other person is registered as the holder
         or joint holder thereof, and such service shall for all purposes of
         these Articles be deemed a sufficient service of such notice on the
         heirs, executors or administrators of the deceased shareholder and all
         joint holders of such shares.

140.     Any notice may bear the name or signature, manual or reproduced, of the
         person giving the notice written or printed.

141.     When a given number of days' notice or notice extending over any other
         period is required to be given, the day of service and the day upon
         which such notice expires shall not, unless it is otherwise provided,
         be counted in such number of days or other period.


                                    INDEMNITY

142.     Every director or officer, former director or officer, or person who
         acts or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, and
         the heirs and legal representatives of such person, in the absence of
         any dishonesty on the part of such person, shall be indemnified by the
         Company against, and it shall be the duty of the directors out of the
         funds of the Company to pay, all costs, losses and expenses, including
         an amount paid to settle an action or claim or satisfy a judgment, that
         such director, officer or person may incur or become liable to pay in
         respect of any claim made against such person or civil, criminal or
         administrative action or proceeding to which such person is made a
         party by reason of being or having been a director or officer of the
         Company or such body corporate, partnership or other association,
         whether the Company is a claimant or party to such action or proceeding
         or otherwise; and the amount for which such indemnity is proved shall
         immediately attach as a lien on the property of the Company and have
         priority as against the shareholders over all other claims.

143.     No director or officer, former director or officer, or person who acts
         or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, in
         the absence of any dishonesty on such person's part, shall be liable
         for the acts, receipts, neglects or defaults of any other director,
         officer or such person, or for joining in any receipt or other act for
         conformity, or for any loss, damage or expense happening to the Company
         through the insufficiency or deficiency of title to any property
         acquired for or on behalf of the Company, or through the insufficiency
         or deficiency of any security in or upon which any of the funds of the
         Company are invested, or for any loss or damage arising from the
         bankruptcy, insolvency or tortious acts of any person with whom any
         funds, securities or

<PAGE>
                                     - 24 -


         effects are deposited, or for any loss occasioned by error of judgment

                                  CERTIFICATES

11.      Certificates of title to shares shall comply with the Act and may
         otherwise be in such form as the directors may from time to time
         determine. Unless the directors otherwise determine, every certificate

         officer at the date of its issue. Any certificate representing shares
         of a class publicly traded on any stock exchange shall be valid and
         binding on the Company if it complies with the rules of such exchange
         whether or not it otherwise complies with this Article.

12.      Except as the directors may determine, each shareholder's shares may be

         in the name of the shareholder.

13.      Where shares are registered in the names of two or more persons, the
         Company shall not be bound to issue more than one certificate or set of
         certificates, and such certificate or set of certificates shall be
         delivered to the person first named on the Register.

14.      Any certificate that has become worn, damaged or defaced may, upon its
         surrender to the directors, be cancelled and replaced by a new
         certificate. Any certificate that has become lost or destroyed may be
         replaced by a new certificate upon proof of such loss or destruction to

         such undertakings of indemnity as the directors deem adequate.

15.      The sum of one dollar or such other sum as the directors from time to
         time determine shall be paid to the Company for every certificate other
         than the first certificate issued to any holder in respect of any share
         or shares.

16.      The directors may cause one or more branch Registers of shareholders to
         be kept in any place or places, whether inside or outside of Nova

                               TRANSFER OF SHARES

17.      The instrument of transfer of any share in the Company shall be signed
         by the transferor. The transferor shall be deemed to remain the holder

         Register in respect thereof and shall be entitled to receive any
         dividend declared thereon before the registration of the transfer.

18.      The instrument of transfer of any share shall be in writing in the
         following form or to the following effect or in such other form as the
         directors may approve from time to time:

                  For value received, _____ hereby sell, assign, and transfer
                  unto ______, _____ shares in the capital of the Company
                  represented by the within certificate, and do hereby
                  irrevocably constitute and appoint _________ attorney to
                  transfer such shares on the books of the Company with full
                  power of substitution in the premises.

                  Dated the ____  day of ___________,

                  Witness:_____________________________

19.      Every instrument of transfer shall be left for registration at the
         Office of the Company, or at any office of its transfer agent where a
         Register is maintained, together with the certificate of the shares to
         be transferred and such other evidence as the Company may require to
         prove title to or the right to transfer the shares.

20.      The directors may require that a fee determined by them be paid before
         or after registration of any transfer.

21.      Every instrument of transfer shall, after its registration, remain in
         the custody of the Company. Any instrument of transfer that the
         directors decline to register shall, except in case of fraud, be
         returned to the person who deposited it.


                             TRANSMISSION OF SHARES


22.      The executors or administrators of a deceased shareholder (not being
         one of several joint holders) shall be the only persons recognized by
         the Company as having any title to the shares registered in the name of
         such shareholder. When a share is registered in the names of two or
         more joint holders, the survivor or survivors and the executors or
         administrators of the deceased shareholder, shall be the only persons
         recognized by the Company as having any title to, or interest in, such
         share.

23.      Notwithstanding anything in these Articles, if the Company has only one
         shareholder (not being one of several joint holders) and that
         shareholder dies, the executors or administrators of the deceased
         shareholder shall be entitled to register themselves in the Register as
         the holders of the shares registered in the name of the deceased
         shareholder whereupon they shall have all the rights given by these
         Articles and by law to shareholders.

24.      Any person entitled to shares upon the death or bankruptcy of any
         shareholder or in any way other than by allotment or transfer, upon
         producing such evidence of entitlement as the directors require, may be
         registered as a shareholder in respect of such shares, or may, without
         being registered, transfer such shares subject to the provisions of
         these Articles respecting the transfer of shares. The directors shall
         have the same right to refuse registration as if the transferee were
         named in an ordinary transfer presented for registration.

                               SURRENDER OF SHARES


25.      The directors may accept the surrender of any share by way of
         compromise of any question as to the holder being properly registered
         in respect thereof. Any share so surrendered may be disposed of in the
         same manner as a forfeited share.


                                  SHARE WARRANT


26.      The Company, with respect to any fully paid-up shares, may issue
         warrants ("Share Warrants") stating that the bearer is entitled to the
         shares therein specified, and may provide, by coupons or otherwise, for
         the payment of future dividends on the shares included in the Share
         Warrants.

27.      The directors may determine and vary the conditions upon which Share
         Warrants will be issued and, without limiting the generality of the
         foregoing, may determine the conditions upon which

         (1)      a new Share Warrant or coupon will be issued in the place of
                  one worn out, defaced, lost or destroyed, or

         (2)      the bearer of a Share Warrant will be entitled to attend and
                  vote at general meetings, or

         (3)      a Share Warrant may be surrendered and the name of the bearer
                  entered in the Register in respect of the shares therein
                  specified.

         Subject to such conditions and to these Articles the bearer of a Share
         Warrant shall be a shareholder to the full extent. The bearer of a
         Share Warrant shall be subject to the conditions for the time being in
         force, whether made before or after the issue of the Share Warrant.


                        INCREASE AND REDUCTION OF CAPITAL

28.      Subject to the Act, the Company may by resolution of its shareholders
         increase its share capital by the creation of new shares of such amount
         as it thinks expedient.\

29.      Subject to the Act, the new shares may be issued upon such terms and
         conditions and with such rights, privileges, limitations, restrictions
         and conditions attached thereto as the Company by resolution of its
         shareholders determines or, if no direction is given, as the directors
         determine.

30.      Except as otherwise provided by the conditions of issue, or by these
         Articles, any capital raised by the creation of new shares shall be
         considered part of the original capital and shall be subject to the
         provisions herein contained with reference to transfer and
         transmission, and otherwise.

31.      The Company may, by special resolution where required, reduce its share
         capital in any way and with and subject to any incident authorized and
         consent required by law.

                              ALTERATION OF CAPITAL

31.      Subject to the Act, the Company may by resolution of its shareholders:

         (1)      consolidate and divide all or any of its share capital into
                  shares of larger amount than its existing shares;

         (2)      convert all or any of its paid-up shares into stock and
                  reconvert that stock into paid-up shares of any denomination;

         (3)      exchange shares of one denomination for another; or

         (4)      cancel shares which, at the date of the passing of the
                  resolution in that behalf, have not been taken or agreed to be
                  taken by any person, and diminish the amount of its share
                  capital by the amount of the shares so cancelled.

33.      Subject to the Act, the Company may by special resolution:

         (1)      subdivide its shares, or any of them, into shares of smaller
                  amount than is fixed by the Memorandum, so, however, that in
                  the subdivision the proportion between the amount paid and the
                  amount, if any, unpaid on each reduced share shall be the same
                  as it was in the case of the share from which the reduced
                  share is derived and the special resolution whereby any share
                  is subdivided may determine that as between the holders of the
                  shares resulting from such subdivision, one or more of such
                  shares shall have some preference or special advantage as
                  regards dividend, capital, voting or otherwise, over, or as
                  compared with, the others or other;

         (2)      convert any part of its issued or unissued share capital into
                  preference shares redeemable or purchasable by the Company;

         (3)      provide for the issue of shares without any nominal or par
                  value provided that, upon any such issue, a declaration
                  executed by the Secretary must be filed with the Registrar
                  stating the number of shares issued and the amount received
                  therefor;

         (4)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares, other than preferred shares,
                  with nominal or par value into the same number of shares
                  without any nominal or par value, and reduce, maintain or
                  increase accordingly its liability on any of its shares so
                  converted; provided that the power to reduce its liability on
                  any of its shares so converted may, where it results in a
                  reduction of capital, only be exercised subject to
                  confirmation by the court as provided by the Act; or

         (5)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares without nominal or par value into
                  the same or a different number of shares with nominal or par
                  value, and for such purpose the shares issued without nominal
                  or par value and replaced by shares with a nominal or par
                  value shall be considered as fully paid, but their aggregate
                  par value shall not exceed the value of the net assets of the
                  Company as represented by the shares without par value issued
                  before the conversion.

34.      Subject to the Act and any provisions attached to such shares, the
         Company may redeem, purchase or acquire any of its shares and the
         directors may determine the manner and the terms for redeeming,
         purchasing or acquiring such shares and may provide a sinking fund on
         such terms as they think fit for the redemption, purchase or
         acquisition of shares of any class or series.


                            INTEREST ON SHARE CAPITAL

35.      The Company may pay interest at a rate not exceeding 6% per year on
         share capital issued and paid-up for the purpose of raising funds to
         defray the expenses of the construction of any works or buildings or
         the provision of any plant which cannot be operated profitably for a
         lengthy period of time. Such interest may be paid for such period and
         may be charged to capital as part of the cost of construction of the
         work or building or of the provision of the plant. The payment of the
         interest shall not operate to reduce the amount paid-up on the shares
         in respect of which it is paid. The accounts of the Company shall show
         full particulars of the payment during the period to which the accounts
         relate.

36.      Subject to the Act and the Memorandum, and without prejudice to any
         special rights previously conferred on the holders of existing shares,
         any share may be issued with such preferred, deferred or other special
         rights, or with such restrictions, whether in regard to dividends,
         voting, return of share capital or otherwise, as the Company may from
         time to time determine by special resolution.


                     MEETINGS AND VOTING BY CLASS OR SERIES

37.      Where the holders of shares of a class or series have, under the Act,
         the Memorandum, the terms or conditions attaching to such shares or
         otherwise, the right to vote separately as a class in respect of any
         matter then, except as provided in the Act, the Memorandum, these
         Articles or such terms or conditions, all the provisions in these
         Articles concerning general meetings (including, without limitation,
         provisions respecting notice, quorum and procedure) shall, mutatis
         mutandis, apply to every meeting of holders of such class or series of
         shares convened for the purpose of such vote.

38.      Unless the rights, privileges, terms or conditions attached to a class
         or series of shares provided otherwise, such class or series of shares
         shall not have the right to vote separately as a class or series upon
         an amendment to the Memorandum or Articles to:

         (1)      increase or decrease any maximum number of authorized shares
                  of such class or series, or increase any maximum number of
                  authorized shares of a class or series having rights or
                  privileges equal or superior to the shares of such class or
                  series;

         (2)      effect an exchange, reclassification or cancellation of all or
                  part of the shares of such class or series; or

         (3)      create a new class or series of shares equal or superior to
                  the shares of such class or series.


                                BORROWING POWERS

39.      The directors on behalf of the Company may:

         (1)      raise or borrow money for the purposes of the Company or any
                  of them;

         (2)      secure, subject to the sanction of a special resolution where
                  required by the Act, the repayment of funds so raised or
                  borrowed in such manner and upon such terms and conditions in
                  all respects as they think fit, and in particular by the
                  execution and delivery of mortgages of the Company's real or
                  personal property, or by the issue of bonds, debentures or
                  other securities of the Company secured by mortgage or other
                  charge upon all or any part of the property of the Company,
                  both present and future;

         (3)      sign or endorse bills, notes, acceptances, cheques, contracts,
                  and other evidence of or securities for funds borrowed or to
                  be borrowed for the purposes aforesaid;

         (4)      pledge debentures as security for loans;

         (5)      guarantee obligations of any person.

40.      Bonds, debentures and other securities may be made assignable, free
         from any equities between the Company and the person to whom such
         securities were issued.

41.      Any bonds, debentures and other securities may be issued at a discount,
         premium or otherwise and with special privileges as to redemption,
         surrender, drawings, allotment of shares, attending and voting at
         general meetings of the Company, appointment of directors and other
         matters.


                                GENERAL MEETINGS

42.      Ordinary general meetings of the Company shall be held at least once in
         every calendar year at such time and place as may be determined by the
         directors and not later than 15 months after the preceding ordinary
         general meeting. All other meetings of the Company shall be called
         special general meetings. Ordinary or special general meetings may be
         held either within or without the Province of Nova Scotia.

43.      The Chair, President, Chief Financial Officer or the directors may at
         any time convene a special general meeting, and the directors, upon the
         requisition of shareholders in accordance with the Act shall forthwith
         proceed to convene such meeting or meetings to be held at such time and
         place or times and places as the directors determine.

44.      The requisition shall state the objects of the meeting requested, be
         signed by the requisitionists and deposited at the Office of the
         Company. It may consist of several documents in like form each signed
         by one or more of the requisitionists.

                                     - 9 -


45.      At least seven clear days' notice, or such longer period of notice as
         may be required by the Act, of every general meeting, specifying the
         place, day and hour of the meeting and, when special business is to be
         considered, the general nature of such business, shall be given to the
         shareholders entitled to be present at such meeting by notice given as
         permitted by these Articles. With the consent in writing of all the
         shareholders entitled to vote at such meeting, a meeting may be
         convened by a shorter notice and in any manner they think fit, or
         notice of the time, place and purpose of the meeting may be waived by
         all of the shareholders.

46.      When it is proposed to pass a special resolution, the two meetings may
         be convened by the same notice, and it shall be no objection to such
         notice that it only convenes the second meeting contingently upon the
         resolution being passed by the requisite majority at the first meeting.

47.      The accidental omission to give notice to a shareholder, or non-receipt
         of notice by a shareholder, shall not invalidate any resolution passed
         at any general meeting.


                                  RECORD DATES

48.      (1)      The directors may fix in advance a date as the record date for
                  the determination of shareholders

         (a)      entitled to receive payment of a dividend or entitled to
                  receive any distribution;

         (b)      entitled to receive notice of a meeting; or

         (c)      for any other purpose.

         (2)      If no record date is fixed, the record date for the
                  determination of shareholders

         (a)      entitled to receive notice of a meeting shall be the day
                  immediately preceding the day on which the notice is given,
                  or, if no notice is given, the day on which the meeting is
                  held; and

         (b)      for any other purpose shall be the day on which the directors
                  pass the resolution relating to the particular purpose.


                         PROCEEDINGS AT GENERAL MEETINGS

49.      The business of an ordinary general meeting shall be to receive and
         consider the financial statements of the Company and the report of the
         directors and the report, if any, of the auditors, to elect directors
         in the place of those retiring, to appoint the auditors of the Company
         for the ensuing fiscal year and to transact any other business which
         under these Articles ought to be transacted at an ordinary general
         meeting.

50.      No business shall be transacted at any general meeting unless the
         requisite quorum is present at the commencement of the business. A
         corporate shareholder of the Company that has a duly authorized agent
         or representative present at any such meeting shall for the purpose of
         this Article be deemed to be personally present at such meeting.

<PAGE>
                                     - 10 -


51.      One person, being a shareholder, proxyholder or representative of a
         corporate shareholder, present and entitled to vote shall constitute a
         quorum for a general meeting, and may hold a meeting.

52.      The Chair shall be entitled to take the chair at every general meeting
         or, if there be no Chair, or if the Chair is not present within fifteen
         15 minutes after the time appointed for holding the meeting, the
         President or, failing the President, a vice-president shall be entitled
         to take the chair. If the Chair, the President or a vice-president is
         not present within 15 minutes after the time appointed for holding the
         meeting or if all such persons present decline to take the chair, the
         shareholders present entitled to vote at the meeting shall choose
         another director as chair and if no director is present or if all the
         directors present decline to take the chair, then such shareholders
         shall choose one of their number to be chair.

53.      If within half an hour from the time appointed for a general meeting a
         quorum is not present, the meeting, if it was convened pursuant to a
         requisition of shareholders, shall be dissolved. If it was convened in
         any other way, it shall stand adjourned to the same day, in the next
         week, at the same time and place. If at the adjourned meeting a quorum
         is not present within half an hour from the time appointed for the
         meeting, the shareholders present shall be a quorum and may hold the
         meeting.

54.      Subject to the Act, at any general meeting a resolution put to the
         meeting shall be decided by a show of hands unless, either before or on
         the declaration of the result of the show of hands, a poll is demanded
         by the chair, a shareholder or a proxyholder; and unless a poll is so
         demanded, a declaration by the chair that the resolution has been
         carried, carried by a particular majority, lost or not carried by a
         particular majority and an entry to that effect in the Company's book
         of proceedings shall be conclusive evidence of the fact without proof
         of the number or proportion of the votes recorded in favour or against
         such resolution.

55.      When a poll is demanded, it shall be taken in such manner and at such
         time and place as the chair directs, and either at once or after an
         interval or adjournment or otherwise. The result of the poll shall be
         the resolution of the meeting at which the poll was demanded. The
         demand of a poll may be withdrawn. When any dispute occurs over the
         admission or rejection of a vote, it shall be resolved by the chair and
         such determination made in good faith shall be final and conclusive.

56.      The chair shall not have a casting vote in addition to any vote or
         votes that the chair has as a shareholder.

57.      The chair of a general meeting may with the consent of the meeting
         adjourn the meeting from time to time and from place to place, but no
         business shall be transacted at any adjourned meeting other than the
         business left unfinished at the meeting that was adjourned.

58.      Any poll demanded on the election of a chair or on a question of
         adjournment shall be taken forthwith without adjournment.

59.      The demand of a poll shall not prevent the continuance of a meeting for
         the transaction of any business other than the question on which a poll
         has been demanded.

                             VOTES OF SHAREHOLDERS

60.      Subject to the Act and to any provisions attached to any class or
         series of shares concerning voting rights

         (1)      on a show of hands every shareholder present in person, every
                  duly authorized representative of a corporate shareholder,
                  and, if not prevented from voting by the Act, every
                  proxyholder, shall have one vote; and

         (2)      on a poll every shareholder present in person, every duly
                  authorized representative of a corporate shareholder, and
                  every proxyholder, shall have one vote for every share held;

         whether or not such representative or proxyholder is a shareholder.

61.      Any person entitled to transfer shares upon the death or bankruptcy of
         any shareholder or in any way other than by allotment or transfer may
         vote at any general meeting in respect thereof in the same manner as if
         such person were the registered holder of such shares so long as the
         directors are satisfied at least 48 hours before the time of holding
         the meeting of such person's right to transfer such shares.

62.      Where there are joint registered holders of any share, any of such
         holders may vote such share at any meeting, either personally or by
         proxy, as if solely entitled to it. If more than one joint holder is
         present at any meeting, personally or by proxy, the one whose name
         stands first on the Register in respect of such share shall alone be
         entitled to vote it. Several executors or administrators of a deceased
         shareholder in whose name any share stands shall for the purpose of
         this Article be deemed joint holders thereof.

63.      Votes may be cast either personally or by proxy or, in the case of a
         corporate shareholder by a representative duly authorized under the
         Act.

64.      A proxy shall be in writing and executed in the manner provided in the
         Act. A proxy or other authority of a corporate shareholder does not
         require its seal. Holders of Share Warrants shall not be entitled to
         vote by proxy in respect of the shares included in such warrants unless
         otherwise expressed in such warrants.

65.      A shareholder of unsound mind in respect of whom an order has been made
         by any court of competent jurisdiction may vote by guardian or other
         person in the nature of a guardian appointed by that court, and any
         such guardian or other person may vote by proxy.

66.      A proxy and the power of attorney or other authority, if any, under
         which it is signed or a notarially certified copy of that power or
         authority shall be deposited at the Office of the Company or at such
         other place as the directors may direct. The directors may, by
         resolution, fix a time not exceeding 72 hours excluding Saturdays and
         holidays preceding any meeting or adjourned meeting before which time
         proxies to be used at that meeting must be deposited with the Company
         at its Office or with an agent of the Company. Notice of the
         requirement for depositing proxies shall be given in the notice calling
         the meeting. The chair of the meeting shall determine all questions as
         to validity of proxies and other instruments of authority.

                                     - 12 -


67.      A vote given in accordance with the terms of a proxy shall be valid
         notwithstanding the previous death of the principal, the revocation of
         the proxy, or the transfer of the share in respect of which the vote is
         given, provided no intimation in writing of the death, revocation or
         transfer is received at the Office of the Company before the meeting or
         by the chair of the meeting before the vote is given.

68.      Every form of proxy shall comply with the Act and its regulations and
         subject thereto may be in the following form:

                  I, _________ of ____________ being a shareholder of _____
                  hereby appoint _______ of ________ (or failing him/her _____
                  of _____) as my proxyholder to attend and to vote for me and
                  on my behalf at the ordinary/special general meeting of the
                  Company, to be held on the ___ day of ____ and at any
                  adjournment thereof, or at any meeting of the Company which
                  may be held prior to [insert specified date or event].

                  [If the proxy is solicited by or behalf of the management of
                  the Company, insert a statement to that effect.]

                  Dated this ____ day of __________ ____.


                           Shareholder

69.      Any resolution passed by the directors, notice of which has been given
         to the shareholders in the manner in which notices are hereinafter
         directed to be given and which is, within one month after it has been
         passed, ratified and confirmed in writing by shareholders entitled on a
         poll to three-fifths of the votes, shall be as valid and effectual as a
         resolution of a general meeting. This Article shall not apply to a
         resolution for winding up the Company or to a resolution dealing with
         any matter that by statute or these Articles ought to be dealt with by
         a special resolution or other method prescribed by statute.

70.      A resolution, including a special resolution, in writing and signed by
         every shareholder who would be entitled to vote on the resolution at a
         meeting is as valid as if it were passed by such shareholders at a
         meeting and satisfies all of the requirements of the Act respecting
         meetings of shareholders.


                                    DIRECTORS

71.      Unless otherwise determined by resolution of shareholders, the number
         of directors shall not be less than one or more than seventeen.

72.      Notwithstanding anything herein contained the directors of the Company
         on the date of its continuance shall continue to be the directors of
         the Company until their successors are appointed or they otherwise
         cease to be directors in accordance with these Articles.

73.      Subject to applicable law, the directors may be paid out of the funds
         or the capital of the Company as remuneration for their service such
         sums, shares or options, if any, as

<PAGE>
                                     - 13 -


         the directors may determine, and such remuneration shall be divided
         among them in such proportions and manner as the directors determine.
         The directors may also be paid their reasonable travelling, hotel and
         other expenses incurred in attending meetings of directors and
         otherwise in the execution of their duties as directors.

74.      The continuing directors may act notwithstanding any vacancy in their
         body, but if their number falls below the minimum permitted, the
         directors shall not, except in emergencies or for the purpose of
         filling vacancies, act so long as their number is below the minimum.


75.

         A director may, in conjunction with the office of director, and on such
         terms as to remuneration and otherwise as the directors arrange or
         determine, hold any other office or place of profit under the Company
         or under any company in which the Company is a shareholder or is
         otherwise interested.

76.      The office of a director shall ipso facto be vacated, if the director:

         (1)      becomes bankrupt or makes an assignment for the benefit of
                  creditors;

         (1)      is, or is found by a court of competent jurisdiction to be, of
                  unsound mind;

         (2)      by notice in writing to the Secretary at the Company's Office,
                  resigns the office of director; or

         (3)      is removed in the manner provided by these Articles.

77.      It shall be the duty of a director who is in any way, whether directly
         or indirectly, interested in a contract or proposed contract with the
         Company to declare the nature of such interest at a meeting of the
         directors of the Company. In the case of a proposed contract the
         declaration required to be made shall be made at a meeting of the
         directors at which the question of entering into the contract is first
         taken into consideration, or if the director was not at the date of
         that meeting interested in the proposed contract, at the next meeting
         of the directors held after the director became so interested, and in a
         case where the director becomes interested in a contract after it is
         made, the declaration shall be made at the first meeting of the
         directors held after the director becomes so interested. A general
         notice given to the directors of the Company by a director to the
         effect that such director is a member of a specified company or firm
         and is to be regarded as interested in any contract which may, after
         the date of the notice, be made with that company or firm shall be
         deemed to be a sufficient declaration of interest in relation to any
         contract so made.


                              ELECTION OF DIRECTORS

78.      At the dissolution of every ordinary general meeting at which their
         successors are elected, all the directors shall retire from office and
         be succeeded by the directors elected at such meeting. Retiring
         directors shall be eligible for re-election.

79.      If at any ordinary general meeting at which an election of directors
         ought to take place no such election takes place, or if no ordinary
         general meeting is held in any year or period of years, the retiring
         directors shall continue in office until their successors are elected.

<PAGE>
                                     - 14 -


80.      The Company may by resolution of its shareholders elect any number of
         directors permitted by these Articles and may determine or alter their
         qualification.

81.      The Company may, by special resolution or in any other manner permitted
         by statute, remove any director before the expiration of such
         director's period of office and may, if desired, appoint a replacement
         to hold office during such time only as the director so removed would
         have held office.

82.      The directors may appoint any other person as a director so long as the
         total number of directors does not at any time exceed the maximum
         number permitted. No such appointment, except to fill a casual vacancy,
         shall be effective unless two-thirds of the directors concur in it. Any
         casual vacancy occurring among the directors may be filled by the
         directors, but any person so chosen shall retain office only so long as
         the vacating director would have retained it if the vacating director
         had continued as director.


                               CHAIR OF THE BOARD

83.      The directors may elect one of their number to be chair and may
         determine the period during which the chair is to hold office. The

88.      The directors may elect or appoint such other officers of the Company,
         having such powers and duties, as they think fit.

89.      If the directors so decide the same person may hold more than one of
         the offices provided for in these Articles.

90.      Notwithstanding anything herein contained the officers of the Company
         on the date of its continuance shall continue to hold office until
         their successors are appointed or they otherwise cease to hold office
         in accordance with these Articles.


                            PROCEEDINGS OF DIRECTORS

91.      The directors may meet together for the dispatch of business, adjourn
         and otherwise regulate their meetings and proceedings, as they think
         fit. Until otherwise determined, a quorum for meetings of the board
         shall be the number of directors then in office, less three (3), of
         which three (3) shall be investor designees.

92.      If at a meeting of directors a quorum is not present, the directors may
         adjourn the meeting to a fixed time and place (provided they shall give
         written notice of such time and place to each director not in
         attendance). At the meeting immediately following the adjourned
         meeting, the directors present at such meeting shall constitute a
         quorum; provided however, that unless a full quorum is present as
         provided in section 91, the directors present at such meeting may not
         transact any business except as specifically set forth in the notice of
         meeting.

93.      A director may participate in a meeting of directors or of a committee
         of directors by means of such telephone or other communications
         facilities as permit all persons participating in the meeting to hear
         each other, and a director participating in such a meeting by such
         means is deemed to be present at that meeting for purposes of these
         Articles.

94.      Meetings of directors may be held either within or without the Province
         of Nova Scotia and the directors may from time to time make
         arrangements relating to the time and place of holding directors'
         meetings, the notices to be given for such meetings and what meetings
         may be held without notice. Unless otherwise provided by such
         arrangements:

         (1)      A meeting of directors may be held at the close of every
                  ordinary general meeting of the Company without notice.

         (2)      Notice of every other directors' meeting may be given as
                  permitted by these Articles to each director at least 48 hours
                  before the time fixed for the meeting.

         (3)      A meeting of directors may be held without formal notice if
                  all the directors are present or if those absent have
                  signified their assent to such meeting or their consent to the
                  business transacted at such meeting.

95.      The President or any director may at any time, and the Secretary, upon
         the request of the President or any director, shall summon a meeting of
         the directors to be held at the Office of

<PAGE>

         the Company. The President, the Chair or a majority of the directors
         may at any time, and the Secretary, upon the request of the President,
         the Chair or a majority of the directors, shall summon a meeting to be
         held elsewhere.

96.      (1)      Questions arising at any meeting of directors shall be decided
                  by a majority of votes. The chair of the meeting may vote as a
                  director but shall not have a second or casting vote.

         (2)      At any meeting of directors the chair shall receive and count
                  the vote of any director not present in person at such meeting
                  on any question or matter arising at such meeting whenever
                  such absent director has indicated by telegram, letter or
                  other writing lodged with the chair of such meeting the manner
                  in which the absent director desires to vote on such question
                  or matter and such question or matter has been specifically
                  mentioned in the notice calling the meeting as a question or
                  matter to be discussed or decided thereat.

97.      If no Chair is elected, or if at any meeting of directors the Chair is
         not present within five minutes after the time appointed for holding
         the meeting, or declines to take the chair, the President, if a
         director, shall preside. If the President is not a director, is not
         present at such time or declines to take the chair, a vice-president
         who is also a director shall preside. If no person described above is
         present at such time and willing to take the chair, the directors
         present shall choose some one of their number to be chair of the
         meeting.

98.      A meeting of the directors at which a quorum is present shall be
         competent to exercise all or any of the authorities, powers and
         discretions for the time being vested in or exercisable by the
         directors generally.

99.      The directors may delegate any of their powers to committees consisting
         of such number of directors as they think fit. Any committee so formed
         shall in the exercise of the powers so delegated conform to any
         regulations that may be imposed on them by the directors.

100.     The meetings and proceedings of any committee of directors shall be
         governed by the provisions contained in these Articles for regulating
         the meetings and proceedings of the directors insofar as they are
         applicable and are not superseded by any regulations made by the
         directors.

101.     All acts done at any meeting of the directors or of a committee of
         directors or by any person acting as a director shall, notwithstanding
         that it is afterwards discovered that there was some defect in the
         appointment of the director or person so acting, or that they or any of
         them were disqualified, be as valid as if every such person had been
         duly appointed and was qualified to be a director.

102.     A resolution in writing and signed by every director who would be
         entitled to vote on the resolution at a meeting is as valid as if it
         were passed by such directors at a meeting.

103.     If any one or more of the directors is called upon to perform extra
         services or to make any special exertions in going or residing abroad
         or otherwise for any of the purposes of the Company or the business
         thereof, the Company may remunerate the director or directors so doing,
         either by a fixed sum or by a percentage of profits or otherwise. Such
         remuneration

<PAGE>
                                     - 17 -


         shall be determined by the directors and may be either in addition to
         or in substitution for remuneration otherwise authorized by these
         Articles.


                                    REGISTERS

104.     The directors shall cause to be kept at the Company's Office in
         accordance with the provisions of the Act a Register of the
         shareholders of the Company, a register of the holders of bonds,
         debentures and other securities of the Company and a register of its
         directors. Branch registers of the shareholders and of the holders of
         bonds, debentures and other securities may be kept elsewhere, either
         within or without the Province of Nova Scotia, in accordance with the
         Act.


                                     MINUTES

105.     The directors shall cause minutes to be entered in books designated for
         the purpose:

         (1)      of all appointments of officers;

         (2)      of the names of directors present at each meeting of directors
                  and of any committees of directors; and

         (3)      of all resolutions and proceedings of meetings of shareholders
                  and of directors.

         Any such minutes of any meeting of directors or of any committee of
         directors or of shareholders, if purporting to be signed by the chair
         of such meeting or by the chair of the next succeeding meeting, shall
         be receivable as prima facie evidence of the matters stated in such
         minutes.


                               POWERS OF DIRECTORS

106.     The management of the business of the Company is vested in the
         directors who, in addition to the powers and authorities by these
         Articles or otherwise expressly conferred upon them, may exercise all
         such powers and do all such acts and things as may be exercised or done
         by the Company and are not hereby or by statute expressly directed or
         required to be exercised or done by the shareholders, but subject
         nevertheless to the provisions of any statute, the Memorandum or these
         Articles. No modification of the Memorandum or these Articles shall
         invalidate any prior act of the directors that would have been valid if
         such modification had not been made.

107.     Without restricting the generality of the terms of any of these
         Articles and without prejudice to the powers conferred thereby, the
         directors may:

                  or contract made by or on behalf of the Company;

         (2)      pay costs, charges and expenses preliminary and incidental to

                  rights or privileges that the Company is authorized to
                  acquire, at such price and generally on such terms and
                  conditions as they think fit;

         (4)      pay for any property, rights or privileges acquired by, or

                  debentures or other securities of the Company;

         (5)      subject to the Act, secure the fulfilment of any contracts or

                  unpaid capital for the time being, or in such other manner as
                  they think fit;

         (6)      appoint, remove or suspend at their discretion such experts,
                  managers, secretaries, treasurers, officers, clerks, agents
                  and servants for permanent, temporary or special services, as
                  they from time to time think fit, and determine their powers
                  and duties and fix their salaries or emoluments and require
                  security in such instances and to such amounts as they think
                  fit;

         (7)      accept a surrender of shares from any shareholder insofar as
                  the law permits and on such terms and conditions as may be
                  agreed;

         (8)      appoint any person or persons to accept and hold in trust for
                  the Company any property belonging to the Company, or in which
                  it is interested, execute and do all such deeds and things as
                  may be required in relation to such trust, and provide for the
                  remuneration of such trustee or trustees;

         (9)      institute, conduct, defend, compound or abandon any legal
                  proceedings by and against the Company, its directors or its

                  and also compound and allow time for payment or satisfaction

                  the Company;

         (10)     refer any claims or demands by or against the Company to

         (13)     provide for the management of the affairs of the Company

         (15)     subject to the Act, execute in the name and on behalf of the
                  Company in favour of any director or other person who may
                  incur or be about to incur any personal liability for the
                  benefit of the Company such mortgages of the Company's

         (16)     give any officer or employee of the Company a commission on

         (17)     set aside out of the profits of the Company before declaring

                                   SOLICITORS

108.     The Company may employ or retain solicitors any of whom may, at the
         request or on the instruction of the directors, the Chair, the
         President or a managing director, attend meetings of the directors or
         shareholders, whether or not the solicitor is a shareholder or a
         director of the Company. A solicitor who is also a director may
         nevertheless charge for services rendered to the Company as a
         solicitor.


                                    THE SEAL

109.     The directors shall arrange for the safe custody of the common seal of
         the Company (the "Seal"). The Seal may be affixed to any instrument in
         the presence of and contemporaneously with the attesting signature of
         (i) any director or officer acting within such person's authority or
         (ii) any person under the authority of a resolution of the directors or
         a committee thereof. For the purpose of certifying documents or
         proceedings the Seal may be affixed by any director or the President, a
         vice-president, the Secretary, an assistant secretary or any other
         officer of the Company without the authorization of a resolution of the
         directors.

<PAGE>
                                     - 20 -


110.     The Company may have facsimiles of the Seal which may be used
         interchangeably with the Seal.


                                    DIVIDENDS

111.     The directors may from time to time declare such dividend as they deem
         proper upon shares of the Company according to the rights and
         restrictions attached to any class or series of shares, and may
         determine the date upon which such dividend will be payable and that it
         will be payable to the persons registered as the holders of the shares
         on which it is declared at the close of business upon a record date. No
         transfer of such shares registered after the record date shall pass any
         right to the dividend so declared.

112.     No dividends shall be payable except out of the profits, retained
         earnings or contributed surplus of the Company and no interest shall be
         payable on any dividend except insofar as the rights attached to any
         class or series of shares provide otherwise.

113.     The declaration of the directors as to the amount of the profits,
         retained earnings or contributed surplus of the Company shall be
         conclusive.

114.     The directors may from time to time pay to the shareholders such
         interim dividends as in their judgment the position of the Company
         justifies.

115.     Subject to the Memorandum, these Articles and the rights and
         restrictions attached to any class or series of shares, dividends may
         be declared and paid to the shareholders in proportion to the amount of
         capital paid-up on the shares (not including any capital paid-up
         bearing interest) held by them respectively.

116.     The directors may deduct from the dividends payable to any shareholder
         amounts due and payable by the shareholder to the Company and may apply
         the same in or towards satisfaction of such amounts so due and payable.

117.     The directors may retain the dividends payable upon shares to which a
         person is entitled or entitled to transfer upon the death or bankruptcy
         of a shareholder or in any way other than by allotment or transfer,
         until such person has become registered as the holder of such shares or
         has duly transferred such shares.

118.     The directors may declare that a dividend be paid by the distribution
         of cash, paid-up shares (at par or at a premium), debentures, bonds or
         other securities of the Company or of any other company or any other
         specific assets held or to be acquired by the Company or in any one or
         more of such ways.

119.     The directors may settle any difficulty that may arise in regard to the
         distribution of a dividend as they think expedient, and in particular
         without restricting the generality of the foregoing may issue
         fractional certificates, may fix the value for distribution of any
         specific assets, may determine that cash payments will be made to any
         shareholders upon the footing of the value so fixed or that fractions
         may be disregarded in order to adjust the rights of all parties, and
         may vest cash or specific assets in trustees upon such trusts for the
         persons entitled to the dividend as may seem expedient to the
         directors.

                                     - 21 -


120.     Any person registered as a joint holder of any share may give effectual
         receipts for all dividends and payments on account of dividends in
         respect of such share.

121.     Unless otherwise determined by the directors, any dividend may be paid
         by a cheque or warrant delivered to or sent through the post to the
         registered address of the shareholder entitled, or, when there are
         joint holders, to the registered address of that one whose name stands
         first on the register for the shares jointly held. Every cheque or
         warrant so delivered or sent shall be made payable to the order of the
         person to whom it is delivered or sent. The mailing or other
         transmission to a shareholder at the shareholder's registered address
         (or, in the case of joint shareholders at the address of the holder
         whose name stands first on the register) of a cheque payable to the
         order of the person to whom it is addressed for the amount of any
         dividend payable in cash after the deduction of any tax which the
         Company has properly withheld, shall discharge the Company's liability
         for the dividend unless the cheque is not paid on due presentation. If
         any cheque for a dividend payable in cash is not received, the Company
         shall issue to the shareholder a replacement cheque for the same amount
         on such terms as to indemnity and evidence of non-receipt as the
         directors may impose. No shareholder may recover by action or other
         legal process against the Company any dividend represented by a cheque
         that has not been duly presented to a banker of the Company for payment
         or that otherwise remains unclaimed for 6 years from the date on which
         it was payable.


                                    ACCOUNTS

122.     The directors shall cause proper books of account to be kept of the
         amounts received and expended by the Company, the matters in respect of
         which such receipts and expenditures take place, all sales and
         purchases of goods by the Company, and the assets, credits and
         liabilities of the Company.

123.     The books of account shall be kept at the head office of the Company or
         at such other place or places as the directors may direct.

124.     The directors shall from time to time determine whether and to what
         extent and at what times and places and under what conditions the
         accounts and books of the Company or any of them shall be open to
         inspection of the shareholders, and no shareholder shall have any right
         to inspect any account or book or document of the Company except as
         conferred by statute or authorized by the directors or a resolution of
         the shareholders.

125.     At the ordinary general meeting in every year the directors shall lay
         before the Company such financial statements and reports in connection
         therewith as may be required by the Act or other applicable statute or
         regulation thereunder and shall distribute copies thereof at such times
         and to such persons as may be required by statute or regulation.


                               AUDITORS AND AUDIT

126.     Except in respect of a financial year for which the Company is exempt
         from audit requirements in the Act, the Company shall at each ordinary
         general meeting appoint an auditor or auditors to hold office until the
         next ordinary general meeting. If at any general meeting at which the
         appointment of an auditor or auditors is to take place and no such

<PAGE>
                                     - 22 -


         appointment takes place, or if no ordinary general meeting is held in
         any year or period of years, the directors shall appoint an auditor or
         auditors to hold office until the next ordinary general meeting.

127.     The first auditors of the Company may be appointed by the directors at
         any time before the first ordinary general meeting and the auditors so
         appointed shall hold office until such meeting unless previously
         removed by a resolution of the shareholders, in which event the
         shareholders may appoint auditors.

128.     The directors may fill any casual vacancy in the office of the auditor
         but while any such vacancy continues the surviving or continuing
         auditor or auditors, if any, may act.

129.     The Company may appoint as auditor any person, including a shareholder,
         not disqualified by statute. 121. An auditor may be removed or replaced
         in the circumstances and in the manner specified in the Act. 122. The
         remuneration of the auditors shall be fixed by the shareholders, or by
         the directors pursuant to authorization given by the shareholders,
         except that the remuneration of an auditor appointed to fill a casual
         vacancy may be fixed by the directors. 123. The auditors shall conduct
         such audit as may be required by the Act and their report, if any,
         shall be dealt with by the Company as required by the Act.


                                     NOTICES

133.     A notice (including any communication or document) shall be
         sufficiently given, delivered or served by the Company upon a
         shareholder, director, officer or auditor by personal delivery at such
         person's registered address (or, in the case of a director, officer or
         auditor, last known address) or by prepaid mail, telegraph, telex,
         facsimile machine or other electronic means of communication addressed
         to such person at such address.

134.     Shareholders having no registered address shall not be entitled to
         receive notice.

135.     The holder of a share warrant shall not, unless otherwise expressed
         therein, be entitled in respect thereof to notice of any general
         meeting of the Company.

136.     All notices with respect to registered shares to which persons are
         jointly entitled may be sufficiently given to all joint holders thereof
         by notice given to whichever of such persons is named first in the
         Register for such shares.

137.     Any notice sent by mail shall be deemed to be given, delivered or
         served on the earlier of actual receipt and the third business day
         following that upon which it is mailed, and in proving such service it
         shall be sufficient to prove that the notice was properly addressed and
         mailed with the postage prepaid thereon. Any notice given by electronic
         means of communication shall be deemed to be given when entered into
         the appropriate transmitting device for transmission. A certificate in
         writing signed on behalf of the Company that the notice was so
         addressed and mailed or transmitted shall be conclusive evidence
         thereof.

138.     Every person who by operation of law, transfer or other means
         whatsoever becomes entitled to any share shall be bound by every notice
         in respect of such share that prior to such person's name and address
         being entered on the Register was duly served in the manner
         hereinbefore provided upon the person from whom such person derived
         title to such share.

139.     Any notice delivered, sent or transmitted to the registered address of
         any shareholder pursuant to these Articles, shall, notwithstanding that
         such shareholder is then deceased and that the Company has notice
         thereof, be deemed to have been served in respect of any registered
         shares, whether held by such deceased shareholder solely or jointly
         with other persons, until some other person is registered as the holder
         or joint holder thereof, and such service shall for all purposes of
         these Articles be deemed a sufficient service of such notice on the
         heirs, executors or administrators of the deceased shareholder and all
         joint holders of such shares.

140.     Any notice may bear the name or signature, manual or reproduced, of the
         person giving the notice written or printed.

141.     When a given number of days' notice or notice extending over any other
         period is required to be given, the day of service and the day upon
         which such notice expires shall not, unless it is otherwise provided,
         be counted in such number of days or other period.


                                    INDEMNITY

142.     Every director or officer, former director or officer, or person who
         acts or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, and
         the heirs and legal representatives of such person, in the absence of
         any dishonesty on the part of such person, shall be indemnified by the
         Company against, and it shall be the duty of the directors out of the
         funds of the Company to pay, all costs, losses and expenses, including
         an amount paid to settle an action or claim or satisfy a judgment, that
         such director, officer or person may incur or become liable to pay in
         respect of any claim made against such person or civil, criminal or
         administrative action or proceeding to which such person is made a
         party by reason of being or having been a director or officer of the
         Company or such body corporate, partnership or other association,
         whether the Company is a claimant or party to such action or proceeding
         or otherwise; and the amount for which such indemnity is proved shall
         immediately attach as a lien on the property of the Company and have
         priority as against the shareholders over all other claims.

         or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, in
         the absence of any dishonesty on such person's part, shall be liable
         for the acts, receipts, neglects or defaults of any other director,
         officer or such person, or for joining in any receipt or other act for
         conformity, or for any loss, damage or expense happening to the Company
         through the insufficiency or deficiency of title to any property
         acquired for or on behalf of the Company, or through the insufficiency
         or deficiency of any security in or upon which any of the funds of the
         Company are invested, or for any loss or damage arising from the
         bankruptcy, insolvency or tortious acts of any person with whom any
         funds, securities or

<PAGE>
                                     - 24 -


         effects are deposited, or for any loss occasioned by error of judgment
         or oversight on the part of such person, or for any other loss, damage
         or misfortune whatsoever which happens in the execution of the duties
         of such person or in relation thereto.

however, that, if at any such meeting, when originally held, the holders of at

(5%) of all Subordinate Voting Shares then outstanding, may transact the
business for which the meeting was originally called, and a resolution duly
passed and carried thereat by not less than 2/3 of the votes cast on a poll at

<PAGE>
                                       4


at all such meetings and each holder of Multiple Voting Shares shall be entitled
at any such meeting to ten votes per Multiple Voting Share held by such holder
as at the record date for such meeting.

5.       CONVERSION OF MULTIPLE VOTING SHARES INTO SUBORDINATE VOTING SHARES

5.1 Subject to compliance with the provisions of Section 5.2 of this Article A,
each holder of Multiple Voting Shares shall be entitled at any time and from
time to time to have all or any part of the Multiple Voting Shares held by such
holder converted into fully paid and non-assessable Subordinate Voting Shares
upon the basis of one Subordinate Voting Share for each Multiple Voting Share
for which the conversion right provided for in this Section 5.1 is exercised, as
specified by the holder of the Multiple Voting Shares in the notice in writing
given to the Company or any transfer agent in exercise of such conversion right.

5.2 Before any holder of Multiple Voting Shares shall be entitled to convert the
same into Subordinate Voting Shares, such holder shall surrender the certificate
or certificates therefor, duly endorsed, at the office of the Company or of any
transfer agent for the Multiple Voting Shares, together with a written notice to
the Company stating therein: the name or names in which the certificate or
certificates for Subordinate Voting Shares are to be issued; the number of
Multiple Voting Shares to be converted; and notice of such holder's election to
convert such Multiple Voting Shares. After giving such notice in writing, the
election of the holder of Multiple Voting Shares shall be irrevocable. The
Company shall, within three (3) days of receipt of such written notice, issue
and deliver at such office to such holder of Multiple Voting Shares, or to the
nominee or nominees of such holder, a certificate or certificates for the number
of Subordinate Voting Shares, as the case may be, to which such holder shall be
entitled as aforesaid. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
certificate or certificates for the Multiple Voting Shares to be converted, and
the person or persons entitled to receive the Subordinate Voting Shares issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such Subordinate Voting Shares, as of such date. The issuance of
certificates for Subordinate Voting Shares, upon conversion of the Multiple
Voting Shares, shall be made without charge to the holder but the holder shall
pay any stamp, documentary or similar tax imposed on or in respect of such
conversion. If less than all of the Multiple Voting Shares represented by any
certificate are to be converted, the holder shall be entitled to receive a new
certificate representing the number of Multiple Voting Shares represented by the
original certificate which are not to be converted.

5.3 The Company will at no time close its transfer books against the transfer of
any Multiple Voting Shares, or of any Subordinate Voting Shares issuable upon
the conversion of any Multiple Voting Shares, in any manner which interferes
with the timely conversion of such Multiple Voting Shares, except as may
otherwise be required to comply with applicable laws.

Shares, as a class, are as follows:

1.1 The Board of Directors of the Company may issue the Preferred Shares at any
time and from time to time in one or more series. Before the first shares of a
particular series are issued, the Board of Directors of the Company, by
resolution, shall fix the number of shares in such series and shall determine,
subject to the limitations set out in the Articles, the designation, rights,
privileges, restrictions and conditions to attach to the shares of such series
including, without limiting the generality of the foregoing, the rate or rates,
amount or method or methods of calculation of preferential dividends, whether
cumulative or non-cumulative or partially cumulative, and whether such rate(s),

the future, the currency or currencies of payment, the date or dates and place
or places of payment thereof and the date or dates from which such preferential
dividends shall accrue, the redemption price and terms and conditions of
redemption (if any), the rights of retraction (if any), and the prices and other
terms and conditions of any rights of retraction and whether any additional
rights of retraction may be vested in such holders in the future, voting rights
(if any) and conversion or exchange rights (if any) and any sinking fund,
purchase fund or other provisions attaching thereto. Such resolution shall be
the only authorization to fix such designation, rights, privileges, restrictions
and conditions and to authorize such issuance and no approval, sanction or
confirmation of such resolution by the shareholders of the Company or otherwise
shall be required. Before the issue of the first shares of a series, the Board
of Directors of the Company shall send to the Registrar (as defined in the
COMPANIES ACT (Nova Scotia)) any necessary documentation in the prescribed form
containing a description of such series including the designation, rights,
privileges, restrictions and conditions determined by the directors.

2.       RANKING OF PREFERRED SHARES

2.1 No rights, privileges, restrictions or conditions attaching to a series of
Preferred Shares shall confer upon a series a priority in respect of dividends
or return of capital over any other series of Preferred Shares then outstanding.
The Preferred Shares of each series shall rank on a parity with the Preferred
Shares of every other series with respect to priority in the payment of
dividends and the return of capital and the distribution of assets of the
Company in the event of the liquidation, dissolution or winding-up of the
Company, whether voluntary or involuntary, or any other distribution of the
assets of the Company among its shareholders for the purpose of winding up its
affairs. When any dividends or amounts payable to the holders of Preferred
Shares on a return of capital are not paid in full, the Preferred Shares of all
series shall participate rateably in respect of such dividends, including
accumulations, if any, in accordance with the sums that would be payable on such
shares if all such dividends were declared and paid in full, and in respect of
any return of capital in accordance with the sums that would be payable on such
return of capital if all sums so payable were paid in full; provided, however,
that in the event of there being insufficient assets to satisfy in full all such
claims as aforesaid, the claims of the holders of such shares with respect to
the return of capital shall first be paid and satisfied and any assets remaining
thereafter shall be applied towards the payment and satisfaction of claims in
respect of dividends.

2.2 The Preferred Shares shall be entitled to priority over the Subordinate
Voting Shares and the Multiple Voting Shares and over any other shares of any
other class of the Company ranking junior to the Preferred Shares with respect
to priority in the payment of


<PAGE>
                                       6


dividends and the return of capital and the distribution of assets in the event
of the liquidation, dissolution or winding-up of the Company, whether voluntary
or involuntary, or any other distribution of the assets of the Company among its
shareholders for the purpose of winding up its affairs.

2.3 The Preferred Shares of any series may also be given such other preferences,
not inconsistent with the provisions hereof, over the Subordinate Voting Shares
and the Multiple Voting Shares and over any other shares ranking junior to the
Preferred Shares as may be determined in the case of such series of Preferred
Shares.

3.       VOTING RIGHTS

3.1 Except as otherwise provided by law or in accordance with any voting rights
which may from time to time be attached to any series of Preferred Shares, the
holders of the Preferred Shares as a class shall not be entitled as such to
receive notice of, to attend or to vote at any meeting of the shareholders of
the Company.

4.       AMENDMENT OF RIGHTS

4.1 The provisions of Sections 1 to 3 , inclusive, in this Article B and of this
Section 4 may be deleted, varied, modified, amended or amplified in whole or in
part, but only with the prior approval of the holders of the Preferred Shares
given as hereinafter specified, provided that the holders of the Preferred
Shares are not entitled to vote separately as a class or, subject to the
COMPANIES ACT (Nova Scotia), as a series, and shall not be entitled to dissent,
upon a proposal to amend these Articles to:

         (a)      increase or decrease any maximum number of authorized
                  Preferred Shares, or increase any maximum number of authorized
                  shares of any other class or series of a class having rights
                  or privileges equal or superior to the Preferred Shares;

         (b)      effect an exchange, reclassification or cancellation of all or
                  part of the Preferred Shares; or

         (c)      create a new class or series of a class of series equal or
                  superior to the Preferred Shares.

4.2 The approval of the holders of the Preferred Shares with respect to any and
all matters hereinbefore referred to in this Article B may be given in writing
by the holders of not less than 2/3 of the Preferred Shares for the time being
outstanding or by resolution duly passed by not less than 2/3 of the votes cast
on a poll at a meeting of the holders of the Preferred Shares duly called and
held for the purpose of considering the subject matter of such resolution and at
which meeting the holders of at least five percent (5%) of the outstanding
Preferred Shares are present in person or represented by proxy in accordance
with the Articles of the Company; provided, however, that, if at any such
meeting, when originally held, the holders of at least five percent (5%) of the
outstanding Preferred Shares are not present in person or so represented by
proxy within 30 minutes after the time fixed for the meeting, then the meeting
shall be adjourned to such date, being not less than 14 days later, and to such
time and place as may be fixed by the chairman of such meeting and not less than
ten days' written notice shall be given of such adjourned meeting, but it shall
not be necessary in such notice to specify the purpose for which


<PAGE>
                                       7


the meeting was originally called. At such adjourned meeting, the holders of
Preferred Shares present in person or so represented by proxy, whether or not
they hold more or less than five percent (5%) of all Preferred Shares then
outstanding, may transact the business for which the meeting was originally
called, and a resolution duly passed and carried thereat by not less than 2/3 of
the votes cast on a poll at such adjourned meeting shall constitute the approval
of the holders of the Preferred Shares hereinbefore mentioned. The formalities
to be observed with respect to the giving of notice of any such original meeting
or adjourned meeting and the conduct thereof shall be those from time to time
prescribed in the Articles of the Company with respect to meetings of
shareholders or in the COMPANIES ACT (Nova Scotia).

4.3 If the deletion, variation, modification, amendment or amplification of the
provisions hereinbefore contained especially affects the rights of the holders
of Preferred Shares of any series, in a manner different from that in or to
which the rights of the holders of Preferred Shares of any other series are
affected, then such deletion, variation, modification, amendment or
amplification shall, in addition to being approved by the holders of the
Preferred Shares as hereinabove set forth, be approved by the holders of the
Preferred Shares of such series so especially affected, which approval may be
given in writing by the holders of not less than 2/3 of the Preferred Shares of
such series or by resolution passed by not less than 2/3 of the votes cast on a
poll at the meeting of the holders of the Preferred Shares of such series, and
the provisions of this Section 4.3 shall apply, mutatis mutandis, with respect
to the holding of such meeting.

4.4 At any meeting of the holders of Preferred Shares as a class or as a series,
each holder of Preferred Shares shall be entitled to one vote in respect of each
Preferred Share held by such holder.

13.      Where shares are registered in the names of two or more persons, the
         Company shall not be bound to issue more than one certificate or set of
         certificates, and such certificate or set of certificates shall be
         delivered to the person first named on the Register.

14.      Any certificate that has become worn, damaged or defaced may, upon its
         surrender to the directors, be cancelled and replaced by a new
         certificate. Any certificate that has become lost or destroyed may be
         replaced by a new certificate upon proof of such loss or destruction to

         such undertakings of indemnity as the directors deem adequate.

15.      The sum of one dollar or such other sum as the directors from time to
         time determine shall be paid to the Company for every certificate other

         or shares.

         be kept in any place or places, whether inside or outside of Nova

17.      The instrument of transfer of any share in the Company shall be signed
         by the transferor. The transferor shall be deemed to remain the holder
         of such share until the name of the transferee is entered in the
         Register in respect thereof and shall be entitled to receive any
         dividend declared thereon before the registration of the transfer.

18.      The instrument of transfer of any share shall be in writing in the
         following form or to the following effect or in such other form as the
         directors may approve from time to time:

                  For value received, __________ hereby sell, assign, and
                  transfer unto ________, shares in the capital of the Company
                  represented by the within certificate, and do hereby
                  irrevocably constitute and appoint

                  ____________ attorney to transfer such shares on the books of
                  the Company with full power of substitution in the premises.

                  Dated the ___ day of _____________, _____

                  Witness: ________________________________

19.      Every instrument of transfer shall be left for registration at the
         Office of the Company, or at any office of its transfer agent where a
         Register is maintained, together with the certificate of the shares to
         be transferred and such other evidence as the Company may require to
         prove title to or the right to transfer the shares.

20.      The directors may require that a fee determined by them be paid before
         or after registration of any transfer.

21.      Every instrument of transfer shall, after its registration, remain in
         the custody of the Company. Any instrument of transfer that the
         directors decline to register shall, except in case of fraud, be
         returned to the person who deposited it.

                             TRANSMISSION OF SHARES

22.      The executors or administrators of a deceased shareholder (not being
         one of several joint holders) shall be the only persons recognized by
         the Company as having any title to the shares registered in the name of
         such shareholder. When a share is registered in the names of two or
         more joint holders, the survivor or survivors and the executors or
         administrators of the deceased shareholder or shareholders, shall be
         the only persons recognized by the Company as having any title to, or
         interest in, such share.

23.      Notwithstanding anything in these Articles, if the Company has only one
         shareholder (not being one of several joint holders) and that
         shareholder dies, the executors or administrators of the deceased
         shareholder shall be entitled to register themselves in the Register as
         the holders of the shares registered in the name of the deceased
         shareholder whereupon they shall have all the rights given by these
         Articles and by law to shareholders.

24.      Any person entitled to shares upon the death or bankruptcy of any
         shareholder or in any way other than by allotment or transfer, upon
         producing such evidence of entitlement as the directors require, may be
         registered as a shareholder in respect of such shares, or may, without
         being registered, transfer such shares subject to the provisions of
         these Articles respecting the transfer of shares. The directors shall
         have the same right to refuse registration as if the transferee were
         named in an ordinary transfer presented for registration.

                               SURRENDER OF SHARES

25.      The directors may accept the surrender of any share by way of
         compromise of any question as to the holder being properly registered
         in respect thereof. Any share so surrendered may be disposed of in the
         same manner as a forfeited share.

                                  SHARE WARRANT


26.      The Company, with respect to any fully paid-up shares, may issue
         warrants ("Share Warrants") stating that the bearer is entitled to the
         shares therein specified, and may provide, by coupons or otherwise, for
         the payment of future dividends on the shares included in the Share
         Warrants.

27.      The directors may determine and vary the conditions upon which Share
         Warrants will be issued and, without limiting the generality of the
         foregoing, may determine the conditions upon which

         (1)      a new Share Warrant or coupon will be issued in the place of
                  one worn out, defaced, lost or destroyed, or

         (2)      the bearer of a Share Warrant will be entitled to attend and
                  vote at general meetings, or

         (3)      a Share Warrant may be surrendered and the name of the bearer
                  entered in the Register in respect of the shares therein
                  specified.

         Subject to such conditions and to these Articles the bearer of a Share
         Warrant shall be a shareholder to the full extent. The bearer of a
         Share Warrant shall be subject to the conditions for the time being in
         force, whether made before or after the issue of the Share Warrant.

                        INCREASE AND REDUCTION OF CAPITAL

28.      Subject to the Act, the Company may by resolution of its shareholders
         increase its share capital by the creation of new shares of such amount
         as it thinks expedient.

29.      Subject to the Act, the new shares may be issued upon such terms and
         conditions and with such rights, privileges, limitations, restrictions
         and conditions attached thereto as the Company by resolution of its
         shareholders determines or, if no direction is given, as the directors
         determine.

30.      Except as otherwise provided by the conditions of issue, or by these
         Articles, any capital raised by the creation of new shares shall be
         considered part of the original capital and shall be subject to the
         provisions herein contained with reference to transfer and
         transmission, and otherwise.

31.      The Company may, by special resolution where required, reduce its share
         capital in any way and with and subject to any incident authorized and
         consent required by law.

                              ALTERATION OF CAPITAL

32.      Subject to the Act, the Company may by resolution of its shareholders:

         (1)      consolidate and divide all or any of its share capital into
                  shares of larger amount than its existing shares;

         (2)      convert all or any of its paid-up shares into stock and
                  reconvert that stock into paid-up shares of any denomination;


         (3)      exchange shares of one denomination for another; or

         (4)      cancel shares which, at the date of the passing of the
                  resolution in that behalf, have not been taken or agreed to be
                  taken by any person, and diminish the amount of its share
                  capital by the amount of the shares so cancelled.

33.      Subject to the Act, the Company may by special resolution:

         (1)      subdivide its shares, or any of them, into shares of smaller
                  amount than is fixed by the Memorandum, so, however, that in
                  the subdivision the proportion between the amount paid and the
                  amount, if any, unpaid on each reduced share shall be the same
                  as it was in the case of the share from which the reduced
                  share is derived and the special resolution whereby any share
                  is subdivided may determine that as between the holders of the
                  shares resulting from such subdivision, one or more of such
                  shares shall have some preference or special advantage as
                  regards dividend, capital, voting or otherwise, over, or as
                  compared with, the others or other;

         (2)      convert any part of its issued or unissued share capital into
                  preference shares redeemable or purchasable by the Company;


         (3)      provide for the issue of shares without any nominal or par
                  value provided that, upon any such issue, a declaration
                  executed by the Secretary must be filed with the Registrar
                  stating the number of shares issued and the amount received
                  therefor;

         (4)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares, other than preferred shares,
                  with nominal or par value into the same number of shares
                  without any nominal or par value, and reduce, maintain or
                  increase accordingly its liability on any of its shares so
                  converted; provided that the power to reduce its liability on
                  any of its shares so converted may, where it results in a
                  reduction of capital, only be exercised subject to
                  confirmation by the court as provided by the Act; or

         (5)      convert all or any of its previously authorized, unissued or
                  issued, fully paid-up shares without nominal or par value into
                  the same or a different number of shares with nominal or par
                  value, and for such purpose the shares issued without nominal
                  or par value and replaced by shares with a nominal or par
                  value shall be considered as fully paid, but their aggregate
                  par value shall not exceed the value of the net assets of the
                  Company as represented by the shares without par value issued
                  before the conversion.

34.      Subject to the Act and any provisions attached to such shares, the
         Company may redeem, purchase or acquire any of its shares and the
         directors may determine the manner and the terms for redeeming,
         purchasing or acquiring such shares and may provide a sinking fund on
         such terms as they think fit for the redemption, purchase or
         acquisition of shares of any class or series.

                            INTEREST ON SHARE CAPITAL

35.      The Company may pay interest at a rate not exceeding 6% per year on
         share capital issued and paid-up for the purpose of raising funds to
         defray the expenses of the construction of any works or buildings or
         the provision of any plant which cannot be operated profitably for a
         lengthy period of time. Such interest may be paid for such period and
         may be charged to capital as part of the cost of construction of the
         work or building or of the provision of the plant. The payment of the
         interest shall not operate to reduce the amount paid-up on the shares
         in respect of which it is paid. The accounts of the Company shall show
         full particulars of the payment during the period to which the accounts
         relate.

                          CLASSES AND SERIES OF SHARES

36.      Subject to the Act and the Memorandum, and without prejudice to any
         special rights previously conferred on the holders of existing shares,
         any share may be issued with such preferred, deferred or other special
         rights, or with such restrictions, whether in regard to dividends,
         voting, return of share capital or otherwise, as the Company may from
         time to time determine by special resolution.

                     MEETINGS AND VOTING BY CLASS OR SERIES

37.      Where the holders of shares of a class or series have, under the Act,
         the Memorandum, the terms or conditions attaching to such shares or
         otherwise, the right to vote separately as a class in respect of any
         matter then, except as provided in the Act, the Memorandum, these
         Articles or such terms or conditions, all the provisions in these
         Articles concerning general meetings (including, without limitation,
         provisions respecting notice, quorum and procedure) shall, mutatis
         mutandis, apply to every meeting of holders of such class or series of
         shares convened for the purpose of such vote.

38.      Unless the rights, privileges, terms or conditions attached to a class
         or series of shares provide otherwise, such class or series of shares
         shall not have the right to vote separately as a class or series upon
         an amendment to the Memorandum or Articles to:

         (1)      increase or decrease any maximum number of authorized shares
                  of such class or series, or increase any maximum number of
                  authorized shares of a class or series having rights or
                  privileges equal or superior to the shares of such class or
                  series;

         (2)      effect an exchange, reclassification or cancellation of all or
                  part of the shares of such class or series; or


<PAGE>
                                      -8-



         (3)      create a new class or series of shares equal or superior to
                  the shares of such class or series.

                                BORROWING POWERS

39.      The directors on behalf of the Company may:

         (1)      raise or borrow money for the purposes of the Company or any
                  of them;

         (2)      secure, subject to the sanction of a special resolution where
                  required by the Act, the repayment of funds so raised or
                  borrowed in such manner and upon such terms and conditions in
                  all respects as they think fit, and in particular by the
                  execution and delivery of mortgages of the Company's real or
                  personal property, or by the issue of bonds, debentures or
                  other securities of the Company secured by mortgage or other
                  charge upon all or any part of the property of the Company,
                  both present and future;

         (3)      sign or endorse bills, notes, acceptances, cheques, contracts,
                  and other evidence of or securities for funds borrowed or to
                  be borrowed for the purposes aforesaid;

         (4)      pledge debentures as security for loans;

         (5)      guarantee obligations of any person.

40.      Bonds, debentures and other securities may be made assignable, free
         from any equities between the Company and the person to whom such
         securities were issued.

41.      Any bonds, debentures and other securities may be issued at a discount,
         premium or otherwise and with special privileges as to redemption,
         surrender, drawings, allotment of shares, attending and voting at
         general meetings of the Company, appointment of directors and other
         matters.

                                GENERAL MEETINGS

42.      Ordinary general meetings of the Company shall be held at least once in
         every calendar year at such time and place as may be determined by the
         directors and not later than 15 months after the preceding ordinary
         general meeting. All other meetings of the Company shall be called
         special general meetings. Ordinary or special general meetings may be
         held either within or without the Province of Nova Scotia.

43.      The Chair, President and Chief Executive Officer, Chief Financial
         Officer or the directors may at any time convene a special general
         meeting, and the directors, upon the requisition of shareholders in
         accordance with the Act shall forthwith proceed to convene such meeting
         or meetings to be held at such time and place or times and places as
         the directors determine.

44.      The requisition shall state the objects of the meeting requested, be
         signed by the requisitionists and deposited at the Office of the
         Company. It may consist of several documents in like form each signed
         by one or more of the requisitionists.

                                      -9-



45.      At least seven clear days' notice, or such longer period of notice as
         may be required by the Act, of every general meeting, specifying the
         place, day and hour of the meeting and, when special business is to be
         considered, the general nature of such business, shall be given to the
         shareholders entitled to be present at such meeting by notice given as
         permitted by these Articles. With the consent in writing of all the
         shareholders entitled to vote at such meeting, a meeting may be
         convened by a shorter notice and in any manner they think fit, or
         notice of the time, place and purpose of the meeting may be waived by
         all of the shareholders.

46.      When it is proposed to pass a special resolution, the two meetings may
         be convened by the same notice, and it shall be no objection to such
         notice that it only convenes the second meeting contingently upon the
         resolution being passed by the requisite majority at the first meeting.

47.      The accidental omission to give notice to a shareholder, or non-receipt
         of notice by a shareholder, shall not invalidate any resolution passed
         at any general meeting.

                                  RECORD DATES

48.      (1) The directors may fix in advance a date as the record date for the
          determination of shareholders

         (a)      entitled to receive payment of a dividend or entitled to
                  receive any distribution;

         (b)      entitled to receive notice of a meeting; or

         (c)      for any other purpose.

         (2)      If no record date is fixed, the record date for the
                  determination of shareholders

         (a)      entitled to receive notice of a meeting shall be the day
                  immediately preceding the day on which the notice is given,
                  or, if no notice is given, the day on which the meeting is
                  held; and

         (b)      for any other purpose shall be the day on which the directors
                  pass the resolution relating to the particular purpose.

                         PROCEEDINGS AT GENERAL MEETINGS

49.      The business of an ordinary general meeting shall be to receive and
         consider the financial statements of the Company and the report of the
         directors and the report, if any, of the auditors, to elect directors
         in the place of those retiring, to appoint the auditors of the Company
         for the ensuing fiscal year and to transact any other business which
         under these Articles ought to be transacted at an ordinary general
         meeting.

50.      No business shall be transacted at any general meeting unless the
         requisite quorum is present at the commencement of the business. A
         corporate shareholder of the Company that has a duly authorized agent
         or representative present at any such meeting shall for the purpose of
         this Article be deemed to be personally present at such meeting.

                                      -10-


51.      Subject to the Act, if the Company has 2 or more shareholders, a quorum
         for the transaction of business at a general meeting shall be 2 persons
         present in person, or by proxy and holding or representing by proxy,
         not less than five percent (5%) of the shares entitled to vote at the
         general meeting.

52.      The Chair shall be entitled to take the chair at every general meeting
         or, if there be no Chair, or if the Chair is not present within fifteen
         15 minutes after the time appointed for holding the meeting, the
         President and Chief Executive Officer or, failing the President and the
         Chief Executive Officer, a vice-president shall be entitled to take the
         chair. If the Chair, the President and Chief Executive Officer or a
         vice-president is not present within 15 minutes after the time
         appointed for holding the meeting or if all such persons present
         decline to take the chair, the shareholders present entitled to vote at
         the meeting shall choose another director as chair and if no director
         is present or if all the directors present decline to take the chair,
         then such shareholders shall choose one of their number to be chair.

53.      If within half an hour from the time appointed for a general meeting a
         quorum is not present, the meeting, if it was convened pursuant to a
         requisition of shareholders, shall be dissolved. If it was convened in
         any other way, it shall stand adjourned to the same day, in the next
         week, at the same time and place. If at the adjourned meeting a quorum
         is not present within half an hour from the time appointed for the
         meeting, the shareholders present shall be a quorum and may hold the
         meeting.

54.      Subject to the Act, at any general meeting a resolution put to the
         meeting shall be decided by a show of hands unless, either before or on
         the declaration of the result of the show of hands, a poll is demanded
         by the chair, a shareholder or a proxyholder; and unless a poll is so
         demanded, a declaration by the chair that the resolution has been
         carried, carried by a particular majority, lost or not carried by a
         particular majority and an entry to that effect in the Company's book
         of proceedings shall be conclusive evidence of the fact without proof
         of the number or proportion of the votes recorded in favour or against
         such resolution.

55.      When a poll is demanded, it shall be taken in such manner and at such
         time and place as the chair directs, and either at once or after an
         interval or adjournment or otherwise. The result of the poll shall be
         the resolution of the meeting at which the poll was demanded. The
         demand of a poll may be withdrawn. When any dispute occurs over the
         admission or rejection of a vote, it shall be resolved by the chair and
         such determination made in good faith shall be final and conclusive.

56.      The chair shall not have a casting vote in addition to any vote or
         votes that the chair has as a shareholder.

57.      The chair of a general meeting may with the consent of the meeting
         adjourn the meeting from time to time and from place to place, but no
         business shall be transacted at any adjourned meeting other than the
         business left unfinished at the meeting that was adjourned.

58.      Any poll demanded on the election of a chair or on a question of
         adjournment shall be taken forthwith without adjournment.

59.      The demand of a poll shall not prevent the continuance of a meeting for
         the transaction of any business other than the question on which a poll
         has been demanded.

                              VOTES OF SHAREHOLDERS

60.      Subject to the Act and to any provisions attached to any class or
         series of shares concerning voting rights

         (1)      on a show of hands every shareholder present in person, every
                  duly authorized representative of a corporate shareholder,
                  and, if not prevented from voting by the Act, every
                  proxyholder, shall have one vote; and

         (2)      on a poll every shareholder present in person, every duly
                  authorized representative of a corporate shareholder, and
                  every proxyholder, shall have one vote for every share held;

         whether or not such representative or proxyholder is a shareholder.

61.      Any person entitled to transfer shares upon the death or bankruptcy of
         any shareholder or in any way other than by allotment or transfer may
         vote at any general meeting in respect thereof in the same manner as if
         such person were the registered holder of such shares so long as the
         directors are satisfied at least 48 hours before the time of holding
         the meeting of such person's right to transfer such shares.

62.      Where there are joint registered holders of any share, any of such
         holders may vote such share at any meeting, either personally or by
         proxy, as if solely entitled to it. If more than one joint holder is
         present at any meeting, personally or by proxy, the one whose name
         stands first on the Register in respect of such share shall alone be
         entitled to vote it. Several executors or administrators of a deceased
         shareholder in whose name any share stands shall for the purpose of
         this Article be deemed joint holders thereof.

63.      Votes may be cast either personally or by proxy or, in the case of a
         corporate shareholder by a representative duly authorized under the
         Act.

64.      A proxy shall be in writing and executed in the manner provided in the
         Act. A proxy or other authority of a corporate shareholder does not
         require its seal. Holders of Share Warrants shall not be entitled to
         vote by proxy in respect of the shares included in such warrants unless
         otherwise expressed in such warrants.

65.      A shareholder of unsound mind in respect of whom an order has been made
         by any court of competent jurisdiction may vote by guardian or other
         person in the nature of a guardian appointed by that court, and any
         such guardian or other person may vote by proxy.

66.      A proxy and the power of attorney or other authority, if any, under
         which it is signed or a notarially certified copy of that power or
         authority shall be deposited at the Office of the Company or with an
         agent of the Company. The directors may, by resolution, fix a time not
         exceeding 72 hours excluding Saturdays and holidays preceding any
         meeting or adjourned meeting before which time proxies to be used at
         that meeting must be deposited with the Company at its Office or with
         an agent of the Company. Notice of the requirement for depositing
         proxies shall be given in the notice calling the meeting. The chair of
         the meeting shall determine all questions as to validity of proxies and
         other instruments of authority.


<PAGE>
                                      -12-


67.      A vote given in accordance with the terms of a proxy shall be valid
         notwithstanding the previous death of the principal, the revocation of
         the proxy, or the transfer of the share in respect of which the vote is
         given, provided no intimation in writing of the death, revocation or
         transfer is received at the Office of the Company before the meeting or
         by the chair of the meeting before the vote is given.

68.      Every form of proxy shall comply with the Act and its regulations and
         subject thereto may be in the following form:

                  I, __________ of __________ being a shareholder of _________
                  hereby appoint ___________ of _________ (or failing him/her
                  _________ of __________) as my proxyholder to attend and to
                  vote for me and on my behalf at the ordinary/special general
                  meeting of the Company, to be held on the __ day _________
                  ____ of and at any adjournment thereof, or at any meeting of
                  the Company which may be held prior to [insert specified date
                  or event].

                  [If the proxy is solicited by or behalf of the management of
                  the Company, insert a statement to that effect.]

                  Dated this _________ day of _________ ____.


                           Shareholder

69.      Any resolution passed by the directors, notice of which has been given
         to the shareholders in the manner in which notices are hereinafter
         directed to be given and which is, within one month after it has been
         passed, ratified and confirmed in writing by shareholders entitled on a
         poll to three-fifths of the votes, shall be as valid and effectual as a
         resolution of a general meeting. This Article shall not apply to a
         resolution for winding up the Company or to a resolution dealing with
         any matter that by statute or these Articles ought to be dealt with by
         a special resolution or other method prescribed by statute.

70.      A resolution, including a special resolution, in writing and signed by
         every shareholder who would be entitled to vote on the resolution at a
         meeting is as valid as if it were passed by such shareholders at a
         meeting and satisfies all of the requirements of the Act respecting
         meetings of shareholders.

                                    DIRECTORS

71.      Unless otherwise determined by resolution of shareholders, the number
         of directors shall not be less than one or more than seventeen.

72.      Notwithstanding anything herein contained the directors of the Company
         on the date of its continuance shall continue to be the directors of
         the Company until their successors are appointed or they otherwise
         cease to be directors in accordance with these Articles.

73.      Subject to applicable law, the directors may be paid out of the funds
         or the capital of the Company as remuneration for their service such
         sums, shares or options, if any, as the


<PAGE>
                                      -13-


         directors may determine, and such remuneration shall be divided among
         them in such proportions and manner as the directors determine. The
         directors may also be paid their reasonable travelling, hotel and other
         expenses incurred in attending meetings of directors and otherwise in
         the execution of their duties as directors.

74.      The continuing directors may act notwithstanding any vacancy in their
         body, but if their number falls below the minimum permitted, the
         directors shall not, except in emergencies or for the purpose of
         filling vacancies, act so long as their number is below the minimum.

75       A director may, in conjunction with the office of director, and on
         such terms as to remuneration and otherwise as the directors arrange or
         determine, hold any other office or place of profit under the Company
         or under any company in which the Company is a shareholder or is
         otherwise interested.

76.      The office of a director shall ipso facto be vacated, if the director:

         (1)      becomes bankrupt or makes an assignment for the benefit of
                  creditors;

         (2)      is, or is found by a court of competent jurisdiction to be, of
                  unsound mind;

         (3)      by notice in writing to the Secretary at the Company's Office,
                  resigns the office of director; or

         (4)      is removed in the manner provided by these Articles.

77.      It shall be the duty of a director who is in any way, whether directly
         or indirectly, interested in a contract or proposed contract with the
         Company to declare the nature of such interest at a meeting of the
         directors of the Company. In the case of a proposed contract the
         declaration required to be made shall be made at a meeting of the
         directors at which the question of entering into the contract is first
         taken into consideration, or if the director was not at the date of
         that meeting interested in the proposed contract, at the next meeting
         of the directors held after the director became so interested, and in a
         case where the director becomes interested in a contract after it is
         made, the declaration shall be made at the first meeting of the
         directors held after the director becomes so interested. A general
         notice given to the directors of the Company by a director to the
         effect that such director is a member of a specified company or firm
         and is to be regarded as interested in any contract which may, after
         the date of the notice, be made with that company or firm shall be
         deemed to be a sufficient declaration of interest in relation to any
         contract so made.

                              ELECTION OF DIRECTORS

78.      At the dissolution of every ordinary general meeting at which their
         successors are elected, all the directors shall retire from office and
         be succeeded by the directors elected at such meeting. Retiring
         directors shall be eligible for re-election.

79.      If at any ordinary general meeting at which an election of directors
         ought to take place no such election takes place, or if no ordinary
         general meeting is held in any year or period of years, the retiring
         directors shall continue in office until their successors are elected.

80.      The Company may by resolution of its shareholders elect any number of
         directors permitted by these Articles and may determine or alter their
         qualification.

81.      The Company may, by special resolution or in any other manner permitted
         by statute, remove any director before the expiration of such
         director's period of office and may, if desired, appoint a replacement
         to hold office during such time only as the director so removed would
         have held office.

82.      The directors may appoint any other person as a director so long as the
         total number of directors does not at any time exceed the maximum
         number permitted. No such appointment, except to fill a casual vacancy,
         shall be effective unless two-thirds of the directors concur in it. Any
         casual vacancy occurring among the directors may be filled by the
         directors, but any person so chosen shall retain office only so long as
         the vacating director would have retained it if the vacating director
         had continued as director.

                               CHAIR OF THE BOARD

83.      The directors may elect one of their number to be chair and may
         determine the period during which the chair is to hold office. The
         chair shall perform such duties and receive such special remuneration
         as the directors may provide.

            PRESIDENT AND CHIEF EXECUTIVE OFFICER AND VICE-PRESIDENTS

84.      The directors shall appoint the President and Chief Executive Officer
         of the Company, who need not be a director, and may determine the
         period for which the President and Chief Executive Officer is to hold
         office. The President and Chief Executive Officer shall have general
         supervision of the business of the Company and shall perform such
         duties as may be assigned from time to time by the directors.

85.      The directors may also appoint vice-presidents, who need not be
         directors, and may determine the periods for which they are to hold
         office. A vice-president shall, at the request of the President and
         Chief Executive Officer or the directors and subject to the directions
         of the directors, perform the duties of the President and Chief
         Executive Officer during the absence, illness or incapacity of the
         President and Chief Executive Officer, and shall also perform such
         duties as may be assigned by the President and Chief Executive Officer
         or the directors.

                             SECRETARY AND TREASURER

86.      The directors shall appoint a Secretary of the Company to keep minutes
         of shareholders' and directors' meetings and perform such other duties
         as may be assigned by the directors. The directors may also appoint a
         temporary substitute for the Secretary who shall, for the purposes of
         these Articles, be deemed to be the Secretary.

87.      The directors may appoint a treasurer of the Company to carry out such
         duties as the directors may assign.

                                    OFFICERS

88.      The directors may elect or appoint such other officers of the Company,
         having such powers and duties, as they think fit.

89.      If the directors so decide the same person may hold more than one of
         the offices provided for in these Articles.

90.      Notwithstanding anything herein contained the officers of the Company
         on the date of its continuance shall continue to hold office until
         their successors are appointed or they otherwise cease to hold office
         in accordance with these Articles.

                            PROCEEDINGS OF DIRECTORS

91.      The directors may meet together for the dispatch of business, adjourn
         and otherwise regulate their meetings and proceedings, as they think
         fit. Until otherwise determined, a quorum for meetings of the board
         shall be:

         (1)      in the case of notice of at least 48 hours before the time
                  fixed for a meeting, a majority of the directors then in
                  office; and

         (2)      in the case of notice of least 24 hours (but less than 48
                  hours) before the time fixed for a meeting, the number of
                  directors then in office, less three (3).

92.      If at a meeting of directors a quorum is not present, the directors may
         adjourn the meeting to a fixed time and place (provided they shall give
         written notice of such time and place to each director not in
         attendance). At the meeting immediately following the adjourned
         meeting, the directors present at such meeting shall constitute a
         quorum; provided however, that unless a full quorum is present as
         provided in section 91, the directors present at such meeting may not
         transact any business except as specifically set forth in the notice of
         meeting.

93.      A director may participate in a meeting of directors or of a committee
         of directors by means of such telephone or other communications
         facilities as permit all persons participating in the meeting to hear
         each other, and a director participating in such a meeting by such
         means is deemed to be present at that meeting for purposes of these
         Articles.

94.      Meetings of directors may be held either within or without the Province
         of Nova Scotia and the directors may from time to time make
         arrangements relating to the time and place of holding directors'
         meetings, the notices to be given for such meetings and what meetings
         may be held without notice. Unless otherwise provided by such
         arrangements:

         (1)      A meeting of directors may be held at the close of every
                  ordinary general meeting of the Company without notice.

         (2)      Notice of every other directors' meeting may be given as
                  permitted by these Articles to each director at least 24 hours
                  before the time fixed for the meeting.


<PAGE>
                                      -16-


         (3)      A meeting of directors may be held without formal notice if
                  all the directors are present or if those absent have
                  signified their assent to such meeting or their consent to the
                  business transacted at such meeting.

95.      The President and Chief Executive Officer or any director may at any
         time, and the Secretary, upon the request of the President and Chief
         Executive Officer or any director, shall summon a meeting of the
         directors to be held at the Office of the Company. The President and
         Chief Executive Officer, the Chair or a majority of the directors may
         at any time, and the Secretary, upon the request of the President and
         Chief Executive Officer, the Chair or a majority of the directors,
         shall summon a meeting to be held elsewhere.

96.      (1)      Questions arising at any meeting of directors shall be decided
                  by a majority of votes. The chair of the meeting may vote as a
                  director but shall not have a second or casting vote.

         (2)      At any meeting of directors the chair shall receive and count
                  the vote of any director not present in person at such meeting
                  on any question or matter arising at such meeting whenever
                  such absent director has indicated by telegram, letter or
                  other writing lodged with the chair of such meeting the manner
                  in which the absent director desires to vote on such question
                  or matter and such question or matter has been specifically
                  mentioned in the notice calling the meeting as a question or
                  matter to be discussed or decided thereat.

97.      If no Chair is elected, or if at any meeting of directors the Chair is
         not present within five minutes after the time appointed for holding
         the meeting, or declines to take the chair, the President and Chief
         Executive Officer, if a director, shall preside. If the President and
         Chief Executive Officer is not a director, is not present at such time
         or declines to take the chair, a vice-president who is also a director
         shall preside. If no person described above is present at such time and
         willing to take the chair, the directors present shall choose some one
         of their number to be chair of the meeting.

98.      A meeting of the directors at which a quorum is present shall be
         competent to exercise all or any of the authorities, powers and
         discretions for the time being vested in or exercisable by the
         directors generally.

99.      The directors may delegate any of their powers to committees consisting
         of such number of directors as they think fit. Any committee so formed
         shall in the exercise of the powers so delegated conform to any
         regulations that may be imposed on them by the directors.

100.     The meetings and proceedings of any committee of directors shall be
         governed by the provisions contained in these Articles for regulating
         the meetings and proceedings of the directors insofar as they are
         applicable and are not superseded by any regulations made by the
         directors.

101.     All acts done at any meeting of the directors or of a committee of
         directors or by any person acting as a director shall, notwithstanding
         that it is afterwards discovered that there was some defect in the
         appointment of the director or person so acting, or that they or any of
         them were disqualified, be as valid as if every such person had been
         duly appointed and was qualified to be a director.


<PAGE>
                                      -17-


102.     A resolution in writing and signed by every director who would be
         entitled to vote on the resolution at a meeting is as valid as if it
         were passed by such directors at a meeting.

103.     If any one or more of the directors is called upon to perform extra
         services or to make any special exertions in going or residing abroad
         or otherwise for any of the purposes of the Company or the business
         thereof, the Company may remunerate the director or directors so doing,
         either by a fixed sum or by a percentage of profits or otherwise. Such
         remuneration shall be determined by the directors and may be either in
         addition to or in substitution for remuneration otherwise authorized by
         these Articles.

                                    REGISTERS

104.     The directors shall cause to be kept at the Company's Office in
         accordance with the provisions of the Act a Register of the
         shareholders of the Company, a register of the holders of bonds,
         debentures and other securities of the Company and a register of its
         directors. Branch registers of the shareholders and of the holders of
         bonds, debentures and other securities may be kept elsewhere, either
         within or without the Province of Nova Scotia, in accordance with the
         Act.

                                     MINUTES

105.     The directors shall cause minutes to be entered in books designated for
         the purpose:

         (1)      of all appointments of officers;

         (2)      of the names of directors present at each meeting of directors
                  and of any committees of directors; and

         (3)      of all resolutions and proceedings of meetings of shareholders
                  and of directors.

         Any such minutes of any meeting of directors or of any committee of
         directors or of shareholders, if purporting to be signed by the chair
         of such meeting or by the chair of the next succeeding meeting, shall
         be receivable as prima facie evidence of the matters stated in such
         minutes.

                               POWERS OF DIRECTORS

106.     The management of the business of the Company is vested in the
         directors who, in addition to the powers and authorities by these
         Articles or otherwise expressly conferred upon them, may exercise all
         such powers and do all such acts and things as may be exercised or done
         by the Company and are not hereby or by statute expressly directed or
         required to be exercised or done by the shareholders, but subject
         nevertheless to the provisions of any statute, the Memorandum or these
         Articles. No modification of the Memorandum or these Articles shall
         invalidate any prior act of the directors that would have been valid if
         such modification had not been made.

                                      -18-


107.     Without restricting the generality of the terms of any of these
         Articles and without prejudice to the powers conferred thereby, the
         directors may:

                  conditions as they think fit;

         (4)      pay for any property, rights or privileges acquired by, or

                  they from time to time think fit, and determine their powers
                  and duties and fix their salaries or emoluments and require

                  fit;

         (7)      accept a surrender of shares from any shareholder insofar as
                  the law permits and on such terms and conditions as may be
                  agreed;

         (8)      appoint any person or persons to accept and hold in trust for
                  the Company any property belonging to the Company, or in which

                                   SOLICITORS

108.     The Company may employ or retain solicitors any of whom may, at the
         request or on the instruction of the directors, the Chair, the
         President or a managing director, attend meetings of the directors or
         shareholders, whether or not the solicitor is a shareholder or a
         director of the Company. A solicitor who is also a director may
         nevertheless charge for services rendered to the Company as a
         solicitor.

                                    THE SEAL

109.     The directors shall arrange for the safe custody of the common seal of
         the Company (the "Seal"). The Seal may be affixed to any instrument in
         the presence of and contemporaneously with the attesting signature of
         (i) any director or officer acting within such person's authority or
         (ii) any person under the authority of a resolution of the directors or
         a committee thereof. For the purpose of certifying documents or
         proceedings the Seal may be affixed by any director or the President, a
         vice-president, the Secretary, an assistant secretary or any other
         officer of the Company without the authorization of a resolution of the
         directors.

110.     The Company may have facsimiles of the Seal which may be used
         interchangeably with the Seal.


                                    DIVIDENDS

111.     The directors may from time to time declare such dividend as they deem
         proper upon shares of the Company according to the rights and
         restrictions attached to any class or series of shares, and may
         determine the date upon which such dividend will be payable and that it
         will be payable to the persons registered as the holders of the shares
         on which it is declared at the close of business upon a record date. No
         transfer of such shares registered after the record date shall pass any
         right to the dividend so declared.

112.     No dividends shall be payable except out of the profits, retained
         earnings or contributed surplus of the Company and no interest shall be
         payable on any dividend except insofar as the rights attached to any
         class or series of shares provide otherwise.

113.     The declaration of the directors as to the amount of the profits,
         retained earnings or contributed surplus of the Company shall be
         conclusive.

114.     The directors may from time to time pay to the shareholders such
         interim dividends as in their judgment the position of the Company
         justifies.

115.     Subject to the Memorandum, these Articles and the rights and
         restrictions attached to any class or series of shares, dividends may
         be declared and paid to the shareholders in proportion to the amount of
         capital paid-up on the shares (not including any capital paid-up
         bearing interest) held by them respectively.

116.     The directors may deduct from the dividends payable to any shareholder
         amounts due and payable by the shareholder to the Company and may apply
         the same in or towards satisfaction of such amounts so due and payable.

117.     The directors may retain the dividends payable upon shares to which a
         person is entitled or entitled to transfer upon the death or bankruptcy
         of a shareholder or in any way other than by allotment or transfer,
         until such person has become registered as the holder of such shares or
         has duly transferred such shares.


<PAGE>
                                      -21-


118.     The directors may declare that a dividend be paid by the distribution
         of cash, paid-up shares (at par or at a premium), debentures, bonds or
         other securities of the Company or of any other company or any other
         specific assets held or to be acquired by the Company or in any one or
         more of such ways.

119.     The directors may settle any difficulty that may arise in regard to the
         distribution of a dividend as they think expedient, and in particular
         without restricting the generality of the foregoing may issue
         fractional certificates, may fix the value for distribution of any
         specific assets, may determine that cash payments will be made to any
         shareholders upon the footing of the value so fixed or that fractions
         may be disregarded in order to adjust the rights of all parties, and
         may vest cash or specific assets in trustees upon such trusts for the
         persons entitled to the dividend as may seem expedient to the
         directors.

120.     Any person registered as a joint holder of any share may give effectual
         receipts for all dividends and payments on account of dividends in
         respect of such share.

121.     Unless otherwise determined by the directors, any dividend may be paid
         by a cheque or warrant delivered to or sent through the post to the
         registered address of the shareholder entitled, or, when there are
         joint holders, to the registered address of that one whose name stands
         first on the register for the shares jointly held. Every cheque or
         warrant so delivered or sent shall be made payable to the order of the
         person to whom it is delivered or sent. The mailing or other
         transmission to a shareholder at the shareholder's registered address
         (or, in the case of joint shareholders at the address of the holder
         whose name stands first on the register) of a cheque payable to the
         order of the person to whom it is addressed for the amount of any
         dividend payable in cash after the deduction of any tax which the
         Company has properly withheld, shall discharge the Company's liability
         for the dividend unless the cheque is not paid on due presentation. If
         any cheque for a dividend payable in cash is not received, the Company
         shall issue to the shareholder a replacement cheque for the same amount
         on such terms as to indemnity and evidence of non-receipt as the
         directors may impose. No shareholder may recover by action or other
         legal process against the Company any dividend represented by a cheque
         that has not been duly presented to a banker of the Company for payment
         or that otherwise remains unclaimed for 6 years from the date on which
         it was payable.

                                    ACCOUNTS

122.     The directors shall cause proper books of account to be kept of the
         amounts received and expended by the Company, the matters in respect of
         which such receipts and expenditures take place, all sales and
         purchases of goods by the Company, and the assets, credits and
         liabilities of the Company.

123.     The books of account shall be kept at the head office of the Company or
         at such other place or places as the directors may direct.

124.     The directors shall from time to time determine whether and to what
         extent and at what times and places and under what conditions the
         accounts and books of the Company or any of them shall be open to
         inspection of the shareholders, and no shareholder shall have any


<PAGE>
                                      -22-


         right to inspect any account or book or document of the Company except
         as conferred by statute or authorized by the directors or a resolution
         of the shareholders.

125.     At the ordinary general meeting in every year the directors shall lay
         before the Company such financial statements and reports in connection
         therewith as may be required by the Act or other applicable statute or
         regulation thereunder and shall distribute copies thereof at such times
         and to such persons as may be required by statute or regulation.

                               AUDITORS AND AUDIT

126.     Except in respect of a financial year for which the Company is exempt
         from audit requirements in the Act, the Company shall at each ordinary
         general meeting appoint an auditor or auditors to hold office until the
         next ordinary general meeting. If at any general meeting at which the
         appointment of an auditor or auditors is to take place and no such
         appointment takes place, or if no ordinary general meeting is held in
         any year or period of years, the directors shall appoint an auditor or
         auditors to hold office until the next ordinary general meeting.

127.     The first auditors of the Company may be appointed by the directors at
         any time before the first ordinary general meeting and the auditors so
         appointed shall hold office until such meeting unless previously
         removed by a resolution of the shareholders, in which event the
         shareholders may appoint auditors.

128.     The directors may fill any casual vacancy in the office of the auditor
         but while any such vacancy continues the surviving or continuing
         auditor or auditors, if any, may act.

129.     The Company may appoint as auditor any person, including a shareholder,
         not disqualified by statute.

130.     An auditor may be removed or replaced in the circumstances and in the
         manner specified in the Act.

131.     The remuneration of the auditors shall be fixed by the shareholders, or
         by the directors pursuant to authorization given by the shareholders,
         except that the remuneration of an auditor appointed to fill a casual
         vacancy may be fixed by the directors.

132.     The auditors shall conduct such audit as may be required by the Act and
         their report, if any, shall be dealt with by the Company as required by
         the Act.

                                     NOTICES

133.     A notice (including any communication or document) shall be
         sufficiently given, delivered or served by the Company upon a
         shareholder, director, officer or auditor by personal delivery at such
         person's registered address (or, in the case of a director, officer or
         auditor, last known address) or by prepaid mail, telegraph, telex,
         facsimile machine or other electronic means of communication addressed
         to such person at such address.

134.     Shareholders having no registered address shall not be entitled to
         receive notice.


<PAGE>
                                      -23-


135.     The holder of a share warrant shall not, unless otherwise expressed
         therein, be entitled in respect thereof to notice of any general
         meeting of the Company.

136.     All notices with respect to registered shares to which persons are
         jointly entitled may be sufficiently given to all joint holders thereof
         by notice given to whichever of such persons is named first in the
         Register for such shares.

137.     Any notice sent by mail shall be deemed to be given, delivered or
         served on the earlier of actual receipt and the third business day
         following that upon which it is mailed, and in proving such service it
         shall be sufficient to prove that the notice was properly addressed and
         mailed with the postage prepaid thereon. Any notice given by electronic
         means of communication shall be deemed to be given when entered into
         the appropriate transmitting device for transmission. A certificate in
         writing signed on behalf of the Company that the notice was so
         addressed and mailed or transmitted shall be conclusive evidence
         thereof.

138.     Every person who by operation of law, transfer or other means
         whatsoever becomes entitled to any share shall be bound by every notice
         in respect of such share that prior to such person's name and address
         being entered on the Register was duly served in the manner
         hereinbefore provided upon the person from whom such person derived
         title to such share.

139.     Any notice delivered, sent or transmitted to the registered address of
         any shareholder pursuant to these Articles, shall, notwithstanding that
         such shareholder is then deceased and that the Company has notice
         thereof, be deemed to have been served in respect of any registered
         shares, whether held by such deceased shareholder solely or jointly
         with other persons, until some other person is registered as the holder
         or joint holder thereof, and such service shall for all purposes of
         these Articles be deemed a sufficient service of such notice on the
         heirs, executors or administrators of the deceased shareholder and all
         joint holders of such shares.

140.     Any notice may bear the name or signature, manual or reproduced, of the
         person giving the notice written or printed.

141.     When a given number of days' notice or notice extending over any other
         period is required to be given, the day of service and the day upon
         which such notice expires shall not, unless it is otherwise provided,
         be counted in such number of days or other period.

                                    INDEMNITY

142.     Every director or officer, former director or officer, or person who
         acts or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, and
         the heirs and legal representatives of such person, in the absence of
         any dishonesty on the part of such person, shall be indemnified by the
         Company against, and it shall be the duty of the directors out of the
         funds of the Company to pay, all costs, losses and expenses, including
         an amount paid to settle an action or claim or satisfy a judgment, that
         such director, officer or person may incur or become liable to pay in
         respect of any claim made against such person or civil, criminal or
         administrative action or proceeding to which such person is made a
         party by reason of being or having been a director or officer of the
         Company or such body corporate, partnership or other association,
         whether the Company is


<PAGE>
                                      -24-


         a claimant or party to such action or proceeding or otherwise; and the
         amount for which such indemnity is proved shall immediately attach as a
         lien on the property of the Company and have priority as against the
         shareholders over all other claims.

143.     No director or officer, former director or officer, or person who acts
         or acted at the Company's request, as a director or officer of the
         Company, a body corporate, partnership or other association of which
         the Company is or was a shareholder, partner, member or creditor, in
         the absence of any dishonesty on such person's part, shall be liable
         for the acts, receipts, neglects or defaults of any other director,
         officer or such person, or for joining in any receipt or other act for
         conformity, or for any loss, damage or expense happening to the Company
         through the insufficiency or deficiency of title to any property
         acquired for or on behalf of the Company, or through the insufficiency
         or deficiency of any security in or upon which any of the funds of the
         Company are invested, or for any loss or damage arising from the
         bankruptcy, insolvency or tortious acts of any person with whom any
         funds, securities or effects are deposited, or for any loss occasioned
         by error of judgment or oversight on the part of such person, or for
         any other loss, damage or misfortune whatsoever which happens in the
         execution of the duties of such person or in relation thereto.

360NETWORKS INC.
1510 - 1066 West Hastings Street
Vancouver, B.C.  V6E 3X1

Dear Sirs/Mesdames:

RE:      360NETWORKS INC. - FORM F-1 REGISTRATION STATEMENT

We are Nova Scotia counsel for 360networks inc. (the "COMPANY"). In this regard,
we have been requested to provide an opinion in connection with the issue of the
Company's Subordinate Voting Shares (the "SHARES") pursuant to a Form F-1
Registration Statement (the "REGISTRATION STATEMENT"), filed with the United
States Securities and Exchange Commission.

For the purposes of our opinion, we have examined the following:

(a)      an executed copy of the Registration Statement;

(b)      the Memorandum and Articles of the Company as attached to a resolution
         of the shareholders of the Company filed today with the Registrar of
         Joint Stock Companies for the Province of Nova Scotia (the
         "REGISTRAR");

(c)      certificate of continuance of the Company issued by the Registrar dated
         April 18, 2000;

(d)      certified copy of resolutions of the directors of the Company providing
         for, among other things, the allotment and issue of the Shares subject
         to the actions of a Pricing Committee established thereby (the
         "DIRECTORS' RESOLUTIONS").

For the purposes of this opinion, we have also examined originals, facsimiles or
copies certified or otherwise identified to our satisfaction, of documents and
instruments, such statutes, such records of corporate proceedings, certificates
of corporate officers, certificates of governmental offices and such other
documents and materials as we have considered necessary or appropriate. In such
examination we have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as


<PAGE>

360 networks inc.

Page 2


originals, the completeness and conformity to the originals of all documents
submitted to us as facsimiles or copies, and the authenticity of the originals
of such facsimiles or copies.

For the purposes of this opinion we have also assumed that :

(a)      the Memorandum and Articles of the Company in the form that we have
         reviewed are genuine and complete and will continue to be the
         Memorandum and Articles of the Company on the date of the issuance
         subject only to the amendments referred to in paragraph (b) below;

(b)      special resolutions effectively in the form reviewed by us amending the
         Memorandum and Articles of the Company of the Company to, INTER ALIA,
         create the Shares, will have been enacted by the shareholders of the
         Company (including the passing of all class votes required) prior to
         the issuance of the Shares and certified copies thereof will have been
         filed with the Registrar; and

(c)      the Pricing Committee takes all necessary action contemplated by, and
         in accordance with, the Directors' Resolutions.

We are qualified to express opinions only with respect to the laws of the
Province of Nova Scotia and the laws of Canada applicable therein.

We are of the opinion that:

1.       The Company is a corporation validly continued and existing under the
         laws of Nova Scotia and has the corporate power and capacity to own and
         lease its property and assets and to carry on its business as described
         in the Registration Statement.

2.       The Shares, when allotted, issued and paid for pursuant to and in
         accordance with the transactions contemplated by the Registration
         Statement, will be issued and outstanding as fully paid and
         non-assessable shares in the capital of the Company, and such issuance
         has been duly authorized by the necessary corporate action on the part
         of the Company.

3.       The Company has the corporate power and capacity to execute and deliver
         the certificates representing the Shares.

Consent is hereby given to the use of our name under the captions "Legal
Matters" in the Prospectus included in the Registration Statement and to the
filing, as an exhibit to the Registration Statement, of this letter. In giving
such consent we do not admit that we come within the category of persons whose
consent is required under Section 7 of the United States Securities Act of 1933.

Yours truly,

STEWART, MCKELVEY, STIRLING & SCALES

          agreed between the parties pursuant to the various Transaction
          Documents that effect the transfers (subject to adjustment as provided

          effected on reasonable economic terms, providing a reasonable return
          to each party and to each TransferCo and not imposing an unreasonable

          from time to time, with respect to the following matters:

          (i)       The parties shall, and 360 shall cause each of the
                    TransferCos to, adjust the terms of the Transaction

                    the intent described in Subsection 3.5(a).

                    or accrued amounts owing pursuant to the Assumed Contracts,
                    with the TransferCos to be responsible for all costs and

                    period prior to the Closing Date and Urbanlink to be
                    responsible for all costs and expenses and, except as

                    from the Closing Date.

          (iv)      Except as expressly provided above, as of the Closing Date
                    the parties shall also adjust (and 360 shall cause the
                    TransferCos to adjust) utility rates and charges, other
                    income from the transferred assets (unless otherwise
                    expressly provided in a Transaction Documents), taxes,
                    insurance, other amounts received from purchasers, licensees

                    Transaction Document) deposits and interest thereon, fuel,
                    prepaid expenses and all other items normally adjusted
                    between a vendor and purchaser in the sale of similar assets
                    so that Urbanlink shall pay all expenses and receive all
                    income relative to the transferred assets (unless otherwise
                    expressly provided in a Transaction Document) prior to the
                    Closing Date and Urbanlink shall bear and pay all expenses
                    and receive all income relative to the transferred assets
                    from and including the Closing Date.

          (v)       Urbanlink shall be responsible for payment of all taxes,
                    rates, duties, assessments and charges levied, rated,

                    responsible for payment of all taxes, rates, duties,

                    in respect of the transferred assets that are payable in
                    respect of all periods of time before the Closing Date.

          (vi)      Without limiting the generality of the foregoing, 360, WFHL
                    and Urbanlink acknowledge and agree that certain of the
                    expenditures that Urbanlink might be required to make under
                    the Municipal Access Agreements relate to telecommunications
                    facilities installed, constructed and/or owned by persons
                    other than Urbanlink including, without limiting the
                    generality of the foregoing, Ledcor Industries Limited (an

                    in respect of which some of the Municipal Access Agreements
                    were given) and Subsidiaries of 360. The parties shall
                    adjust between themselves, from time to time, any amounts
                    payable under the Municipal Access Agreements, to effect a
                    just and equitable allocation of such payments among the
                    persons

5.1  WFHL shall subscribe for Carrier Holdco voting non-participating shares
     representing 2/3 of the total number of such shares to be issued, for
     nominal consideration.

5.2  WFHL shall transfer to Carrier Holdco Subordinate Voting Shares of 360
     having a fair market value equal to 49/51 of the fair value of the
     Urbanlink preferred shares and Urbanlink common shares transferred by
     360-Holdco to Carrier Holdco determined using the price to the public of
     the Subordinate Voting Shares in 360's initial public offering (the "IPO
     Price"), and WFHL shall receive in return Carrier Holdco non-voting
     participating shares representing 49% of the total number to be issued. As
     the Closing Date shall occur before the IPO, the number of shares
     transferred on the Closing Date shall be calculated on the assumption that
     the IPO Price is US$17.00 and the number of transferred shares shall be
     adjusted as soon as practicable after the Closing Date to equal the number
     of shares determined using the IPO Price.

PART 6 - POST CLOSING TRANSFERS

6.1  From time to time after the completion of those segments of the builds that
     are not complete on the Closing Date and the final allocation or

     described in Sections 2.1 and 2.2 of Schedule 2, on a date or dates to be
     determined by agreement between 360 and WFHL, acting reasonably, the
     TransferCos shall transfer assets to 360-Holdco for a series of 360-Holdco
     preferred shares having a redemption amount equal to the estimated fair
     value of the transferred assets, reduced by the amount of any liabilities
     assumed by 360-Holdco. A separate series of 360-Holdco preferred shares
     shall be issued to each TransferCo. The assets to be transferred in
     exchange for such shares shall be those assets described in Sections 2.1,
     2.2, 2.3 and 2.4 on Schedule 2 (collectively, the "Post-Closing Assets").

6.2  360-Holdco shall transfer the Post-Closing Assets to Carrier Holdco for a
     number of common shares to be determined by considering the estimated fair
     value of the Post-Closing Assets (reduced by the amount of any liabilities
     assumed by Carrier Holdco), the estimated fair value of the then issued
     Carrier Holdco shares, and the estimated fair value of the subscription to
     be made by WFHL under Section 6.3, in return for Carrier Holdco non-voting
     participating shares representing 51% of the total number of shares to be
     issued under Sections 6.2 and 6.3.

6.3  WFHL shall transfer to Carrier Holdco additional Subordinate Voting Shares
     of 360 having a fair value equal to 49/51 of the estimated fair value of
     the Post-Closing Assets (reduced by the amount of any liabilities assumed
     by Carrier Holdco), determined using the then current market prices of the
     Subordinate Voting Shares, and WFHL shall receive in return Carrier Holdco
     non-voting participating shares representing 49% of the total number of
     shares to be issued under Sections 6.2 and 6.3.

     be filed by the transferor and the transferee in respect of each of the

     eligible, and such elections shall elect that the transfers be effected at
     the transferor's cost amount for the transferred assets, unless otherwise

5.4  If:

     (a)  the Taxing Authority at any time proposes to issue, or does issue, any

          whereupon interest shall accrue on the principal amount in default at
          the rate of 2% per annum above the prime lending rate established from

          the repurchase of the Share Consideration is less than the Adjusted
          Fair Market Value, the loss shall be a debt payable to the Vendor by
          the Purchaser, on demand, without interest except in the event of
          default whereupon interest shall accrue on the principal amount in
          default at the rate of 2% per annum above the prime lending rate
          established from time to time by the Vancouver main branch of the
          Vendor's bank, calculated from the date of default until the date
          payment is made.

5.7  If, because of the operation of section 5.4, the Fair Market Value is
determined at the Effective Date to be equal to the Adjusted Fair Market Value,
then the Redemption Amount shall be adjusted NUNC PRO TUNC to reflect an amount
equal to the Adjusted Fair Market Value, and all necessary adjustments, payments
and repayments, if any, as may be required by virtue of such


                                      -4-

adjustment, shall forthwith be made between the Purchaser and the Vendor in

6.3  If:

     (a)  the Taxing Authority proposes to issue, or does issue, any assessment
          or reassessments that impose, or would impose, any liability for tax

          adjusted cost base of the Assets is the Revised Adjusted Cost Base;

     (b)  the parties agree, or a Court or tribunal of competent jurisdiction
          finally adjudges, that the adjusted cost base of the Assets is the
          Revised Adjusted Cost Base; and

     (c)  the Taxing Authority will accept as effective an amended Election of
          the parties;

then:

     (d)  the Adjusted Cost Base shall be deemed to have always been, and the
          Adjusted Cost Base wherever referred to in this Agreement, shall be
          read as meaning the Revised Adjusted Cost Base;

     (e)  the Elected Amount shall be deemed to have always been, and the
          Elected Amount wherever referred to in this Agreement shall be read as
          meaning, an amount equal to the Adjusted Elected Amount; and

     (f)  the parties shall take all such steps and jointly execute all such
          documents and elections as may be required and allowed so that the
          aggregate of the amounts elected for purposes of subsection 85(1) of
          the Act with respect to the purchase and sale of the Assets shall be
          equal to the Adjusted Elected Amount.

agreements to be executed and delivered as described in this Section 5, and such
Shelter Licenses shall entitle Purchaser (at no cost to Purchaser during the
Initial Term) to keep such Communications Shelters at the location supplied and
(at Purchaser's cost) to maintain, repair and improve any equipment or materials
in such Communications Shelters and to have exclusive access to the interior of
the Communications Shelters.

                                   ARTICLE 4
                                 EFFECTIVE DATE

                                 PURCHASE PRICE

and shall be paid and satisfied by the Purchaser issuing to the Vendor the Share
Consideration.

5.2  The Purchaser shall add the Stated Capital Addition to the stated capital
account being maintained for the class of shares of which the Share

5.4  If:

     (a)  the Taxing Authority at any time proposes to issue, or does issue, any
          assessment or reassessments that impose, or would impose, any
          liability for tax of any nature or kind on either of the parties on
          the basis that the aggregate of the fair market value of the Assets at
          the Effective Date is a greater or lesser amount than the Elected Fair
          Market Value; and

     (b)  the parties agree, or a Court or tribunal of competent jurisdiction
          finally adjudges, that the aggregate of the fair market value of the
          Assets as of the Effective Date is the Adjusted Fair Market Value;

then:

     (c)  the Fair Market Value shall be deemed to have always been, and the
          Fair Market Value wherever referred to in this Agreement shall be read
          as meaning, the Adjusted Fair Market Value.

5.5  If not all of the shares forming the Share Consideration have been redeemed
or purchased by the Purchaser on or prior to the date of determination of the
Adjusted Fair Market Value of the Assets, then the Redemption Amount for each of
the shares forming the Share Consideration which are still outstanding at that
time, shall be adjusted in accordance with section 5.7 hereof.

5.6  If the Purchaser has repurchased or redeemed all of the shares forming the
Share Consideration at or before the time that the Adjusted Fair Market Value is
determined, then:

     (a)  where the aggregate of the amounts previously paid by the Purchaser on
          the repurchase of the Share Consideration exceeds the Adjusted Fair
          Market Value, the excess shall be a debt payable to the Purchaser by
          the Vendor, on demand, without interest except in the event of default
          whereupon interest shall accrue on the principal amount in default at
          the rate of 2% per annum above the prime lending rate established from
          time to time by the Vancouver main branch of the Purchaser's bank,
          calculated from the date of default until the date payment is made;
          and

     (b)  where the aggregate of the amounts previously paid by the Purchaser on
          the repurchase of the Share Consideration is less than the Adjusted
          Fair Market Value, the loss shall be a debt payable to the Vendor by
          the Purchaser, on demand, without interest except in the event of
          default whereupon interest shall accrue on the principal amount in
          default at the rate of 2% per annum above the prime lending rate
          established from time to time by the Vancouver main branch of the
          Vendor's bank, calculated from the date of default until the date
          payment is made.

5.7  If, because of the operation of section 5.4, the Fair Market Value is
determined at the Effective Date to be equal to the Adjusted Fair Market Value,
then the Redemption Amount shall be adjusted NUNC PRO TUNC to reflect an amount
equal to the Adjusted Fair Market Value, and all necessary adjustments, payments
and repayments, if any, as may be required by virtue of such


                                      -4-

adjustment, shall forthwith be made between the Purchaser and the Vendor in
accordance with the provisions of section 5.6, MUTATIS MUTANDIS.

6.1  The Vendor and Purchaser shall jointly make the Election.

6.2  Subject to the provisions of this Agreement, for purposes of the Election
the parties agree that the Elected Amount shall be the Adjusted Cost Base of the
Assets, which determination is final and binding on the parties.

6.3  If:

     (a)  the Taxing Authority proposes to issue, or does issue, any assessment
          or reassessments that impose, or would impose, any liability for tax
          of any nature or kind on either of the parties on the basis that the
          adjusted cost base of the Assets is the Revised Adjusted Cost Base;

     (b)  the parties agree, or a Court or tribunal of competent jurisdiction
          finally adjudges, that the adjusted cost base of the Assets is the
          Revised Adjusted Cost Base; and

     (c)  the Taxing Authority will accept as effective an amended Election of
          the parties;

then:

     (d)  the Adjusted Cost Base shall be deemed to have always been, and the
          Adjusted Cost Base wherever referred to in this Agreement, shall be
          read as meaning the Revised Adjusted Cost Base;

     (e)  the Elected Amount shall be deemed to have always been, and the
          Elected Amount wherever referred to in this Agreement shall be read as
          meaning, an amount equal to the Adjusted Elected Amount; and

     (f)  the parties shall take all such steps and jointly execute all such
          documents and elections as may be required and allowed so that the
          aggregate of the amounts elected for purposes of subsection 85(1) of
          the Act with respect to the purchase and sale of the Assets shall be
          equal to the Adjusted Elected Amount.

in such Communications Shelters and to have exclusive access to the interior of
the Communications Shelters.

5.4  If:

     (a)  the Taxing Authority at any time proposes to issue, or does issue, any
          assessment or reassessments that impose, or would impose, any
          liability for tax of any nature or kind on either of the parties on

     (c)  the Fair Market Value shall be deemed to have always been, and the

     (a)  where the aggregate of the amounts previously paid by the Purchaser on
          the repurchase of the Share Consideration exceeds the Adjusted Fair
          Market Value, the excess shall be a debt payable to the Purchaser by
          the Vendor, on demand, without interest except in the event of default
          whereupon interest shall accrue on the principal amount in default at
          the rate of 2% per annum above the prime lending rate established from
          time to time by the Vancouver main branch of the Purchaser's bank,
          calculated from the date of default until the date payment is made;
          and

     (b)  where the aggregate of the amounts previously paid by the Purchaser on
          the repurchase of the Share Consideration is less than the Adjusted
          Fair Market Value, the loss shall be a debt payable to the Vendor by
          the Purchaser, on demand, without interest except in the event of
          default whereupon interest shall accrue on the principal amount in
          default at the rate of 2% per annum above the prime lending rate
          established from time to time by the Vancouver main branch of the
          Vendor's bank, calculated from the date of default until the date
          payment is made.

5.7  If, because of the operation of section 5.4, the Fair Market Value is
determined at the Effective Date to be equal to the Adjusted Fair Market Value,
then the Redemption Amount shall be adjusted NUNC PRO TUNC to reflect an amount
equal to the Adjusted Fair Market Value, and all necessary adjustments, payments
and repayments, if any, as may be required by virtue of such


                                      -4-

adjustment, shall forthwith be made between the Purchaser and the Vendor in

6.3  If:

     (a)  the Taxing Authority proposes to issue, or does issue, any assessment
          or reassessments that impose, or would impose, any liability for tax
          of any nature or kind on either of the parties on the basis that the
          adjusted cost base of the Assets is the Revised Adjusted Cost Base;

     (b)  the parties agree, or a Court or tribunal of competent jurisdiction
          finally adjudges, that the adjusted cost base of the Assets is the
          Revised Adjusted Cost Base; and

     (c)  the Taxing Authority will accept as effective an amended Election of
          the parties;

then:

     (d)  the Adjusted Cost Base shall be deemed to have always been, and the
          Adjusted Cost Base wherever referred to in this Agreement, shall be
          read as meaning the Revised Adjusted Cost Base;

     (e)  the Elected Amount shall be deemed to have always been, and the
          Elected Amount wherever referred to in this Agreement shall be read as
          meaning, an amount equal to the Adjusted Elected Amount; and

     (f)  the parties shall take all such steps and jointly execute all such
          documents and elections as may be required and allowed so that the
          aggregate of the amounts elected for purposes of subsection 85(1) of
          the Act with respect to the purchase and sale of the Assets shall be
          equal to the Adjusted Elected Amount.

3.   ASSETS INCLUDE ROW RIGHTS

     (a)  The Assets include the grant by the Vendor to the Purchaser with

          Term of a sublicense of the ROW Rights to be granted pursuant to a

<PAGE>

4.   INTEREST IN SUPPORT STRUCTURES

The Assets include the grant by the Vendor to the Purchaser, for no additional
consideration, of an undivided interest in all Support Structures related
thereto (including, for greater clarity, related Utilities Shelters) equal to
its proportionate share in the total Strands from time to time making up the
applicable segment of the Fiber Optic Cable(s) that will be shared with others
(such undivided interest shall be referred to as the "Support Structures
Interests"). The Purchaser acknowledges that the Support Structures will be
owned by all owners of Strands permitted by the Rights-of-Way and may be used by
such owners or others granted rights in the strands.

5.   COMMUNICATIONS SHELTERS AND CO-LOCATION FACILITIES

The Assets include the Communications Shelters and Co-Location Facilities, but
not any interest in the land upon which such Communication Shelters and
Co-Location Facilities are located. Where Exhibit A-1 indicates that the Assets
include a communications shelter, then the Assets include all right, title and
interest of the Vendor in and to such communications shelter. Where Exhibit A-1
indicates that the Assets include co-location facilities, the Assets include the
grant by the Vendor to the Purchaser of non-exclusive licences of occupation in
respect of such co-location facilities, to be included in a co-location
agreement in a form acceptable to the Purchaser and the Vendor, acting
reasonably and in good faith.

The Assets include the grant by the Vendor to the Purchaser of non-exclusive
licenses of occupation in a form acceptable to the Purchaser and the Vendor,
acting reasonably and in good faith (a "Shelter License") in respect of each
Communications Shelter and Co-Location Facility that is not located on one of
the Underlying Rights, for the Initial Term, pursuant to Shelter License
agreements to be executed and delivered as described in this Section 5, and such
Shelter Licenses shall entitle Purchaser (at no cost to Purchaser during the
Initial Term) to keep such Communications Shelters at the location supplied and
(at Purchaser's cost) to maintain, repair and improve any equipment or materials
in such Communications Shelters and to have exclusive access to the interior of
the Communications Shelters.

          the repurchase of the Share Consideration is less than the Adjusted
          Fair Market Value, the loss shall be a debt payable to the Vendor by
          the Purchaser, on demand, without interest except in the event of
          default whereupon interest shall accrue on the principal amount in
          default at the rate of 2% per annum above the prime lending rate
          established from time to time by the Vancouver main branch of the
          Vendor's bank, calculated from the date of default until the date
          payment is made.

5.7  If, because of the operation of section 5.4, the Fair Market Value is
determined at the Effective Date to be equal to the Adjusted Fair Market Value,
then the Redemption Amount shall be adjusted NUNC PRO TUNC to reflect an amount
equal to the Adjusted Fair Market Value, and all necessary adjustments, payments
and repayments, if any, as may be required by virtue of such


                                      -4-

adjustment, shall forthwith be made between the Purchaser and the Vendor in
accordance with the provisions of section 5.6, MUTATIS MUTANDIS.

                       JOINT ELECTION AND ELECTED AMOUNTS

6.1  The Vendor and Purchaser shall jointly make the Election.

6.2  Subject to the provisions of this Agreement, for purposes of the Election
the parties agree that the Elected Amount shall be the Adjusted Cost Base of the
Assets, which determination is final and binding on the parties.

6.3  If:

     (a)  the Taxing Authority proposes to issue, or does issue, any assessment
          or reassessments that impose, or would impose, any liability for tax
          of any nature or kind on either of the parties on the basis that the
          adjusted cost base of the Assets is the Revised Adjusted Cost Base;

     (b)  the parties agree, or a Court or tribunal of competent jurisdiction
          finally adjudges, that the adjusted cost base of the Assets is the
          Revised Adjusted Cost Base; and

     (c)  the Taxing Authority will accept as effective an amended Election of
          the parties;

then:

     (d)  the Adjusted Cost Base shall be deemed to have always been, and the
          Adjusted Cost Base wherever referred to in this Agreement, shall be
          read as meaning the Revised Adjusted Cost Base;

     (e)  the Elected Amount shall be deemed to have always been, and the
          Elected Amount wherever referred to in this Agreement shall be read as
          meaning, an amount equal to the Adjusted Elected Amount; and

     (f)  the parties shall take all such steps and jointly execute all such
          documents and elections as may be required and allowed so that the
          aggregate of the amounts elected for purposes of subsection 85(1) of
          the Act with respect to the purchase and sale of the Assets shall be
          equal to the Adjusted Elected Amount.

2.2   ADDITIONAL STRANDS

On the acquisition of any of the Phase II Strands by Urbanlink, Services (or
such other Subsidiary of 360 as 360 may designate from time to time by notice in
writing to Urbanlink) shall execute a Capacity Purchase Agreement in the form
attached as Schedule "C" or in such other form as may then be agreed between
Services (or such designated Subsidiary of 360) and Urbanlink, acting reasonably
and in good faith, in relation to such Phase II Strands.

2.3   CAPACITY

Unless otherwise agreed from time to time by 360 and Urbanlink, and except as
specifically provided below, for each of the Strands, the Capacity Purchase
Agreement shall be an IRU capacity agreement by which Services (or the
designated Subsidiary of 360) shall acquire from Urbanlink an IRU capacity
purchase agreement for four OC-192s or the equivalent on each such Strand, or
such greater capacity as may result from the replacement or upgrading of
telecommunications equipment, or the adding of telecommunications equipment, as
described in Section 3.3. For each of the Strands described in Schedule A as
being between Edmonton and Toronto, unless otherwise agreed from time to time by
360 and Urbanlink, the Capacity Purchase Agreement shall be an IRU capacity
agreement by which Services (or the designated Subsidiary of 360) shall acquire

2.4   ELECTION TO ACCEPT REDUCED CAPACITY

By notice in writing to Urbanlink, Services (or the designated Subsidiary of
360) may elect to acquire less capacity than specified above; provided however
that Services (or such designated Subsidiary) shall not elect to acquire units
of capacity smaller than OC-48; and provided further that if Services (or such
designated Subsidiary) so elects, Services (or such designated Subsidiary) may
subsequently elect to acquire the balance of the capacity specified in Section
2.3. To the extent that a Capacity Purchase Agreement is for less than four
OC-192s, the amount per Strand per route kilometer specified in Section 5.1
shall be prorated accordingly. For greater clarity, Urbanlink shall have the
right to lease or IRU any remaining capacity to other customers.

time to time to light these Strands to which the Capacity Purchase Agreement
relates. The selection of the equipment shall be subject to the prior written
approval of Services, acting reasonably, and in good faith. Without limiting the
generality of the foregoing, it shall not be unreasonable for Services to
consider the compatibility of such equipment with the other equipment owned or
used by Services or other Subsidiaries of 360 in Canadian and other
jurisdictions.

      (a)   If Services desires that Urbanlink replace or upgrade its

            equipment, in order to increase the capacity available to Services
            or the designated Subsidiary of 360, then Services (or the
            designated Subsidiary of 360) shall provide notice in writing to
            Urbanlink specifying its request in reasonable detail.

      (b)   Within 15 days thereafter, representatives of 360 and Urbanlink
            shall meet to discuss such request, and shall negotiate reasonably

            both 360 and Urbanlink, acting reasonably, for payments and cost
            recovery, such terms to be consistent with the reasonable needs and
            requirements of Services, the designated Subsidiary of 360,
            Urbanlink, and the customers of Services and any designated
            Subsidiary of 360.

7.6   ASSIGNMENT

      (a)   This Agreement is not assignable by Urbanlink in whole or in part
            without the prior written consent of 360, such consent not to be
            unreasonably delayed. This Agreement is not assignable by 360 or
            Services without the prior written consent of Urbanlink, such
            consent not to be unreasonably delayed. Any attempt by any party to
            assign any of the rights or to delegate any of the duties or
            obligations of this Agreement without such prior written consent is
            void.

      (b)   Notwithstanding the foregoing, the interests of any party may be
            assigned by such party to an Affiliate, provided that such Affiliate
            delivers to the other parties a written undertaking to be bound by
            the provisions of this Agreement in all respects and to the same
            extent as the assignor is bound and provided further that the
            assignor will continue to be bound by all the obligations hereunder
            as if such assignment had not occurred and shall perform such
            obligations to the extent that such Affiliate fails to do so.

      (c)   Notwithstanding the foregoing, the interests of a party under this
            Agreement (including, without limitation, in the case of Urbanlink,
            the right to receive any and all amounts payable to Urbanlink under
            this Agreement) may be assigned by such party by way of collateral
            security to a lender without the consent of the other parties,
            provided however that any such lender agrees in writing that:

            (i)   the rights and interest of the lender are subject to the
                  rights and interests of the parties other than the assignor
                  under this Agreement;

            (ii)  prior to realizing on such collateral security it will provide
                  notice to the other parties giving them the opportunity to
                  cure the default; and

            (iii) should such security be realized with the result that the
                  title or interest of the assignor, as the case may be, is
                  vested in an assignee, acquirer or other successor in title or
                  interest (including the lender if such is the case)
                  ("Successor"), then the lender will cause such Successor to
                  enter into a written agreement with the other parties to be
                  bound by the provisions of this Agreement in all respects and
                  to the same extent as the assignor was bound and this from the
                  date the title or interest is transferred and provided further
                  that the assignor will continue to be bound by all the
                  obligations under this Agreement as if such transfer of title
                  or interest had not occurred and will perform such obligations
                  to the extent that the Successor fails to do so.

7.7   FORCE MAJEURE

The failure or delay of any party to this Agreement to perform any obligation
under this Agreement solely by reason of acts of God, acts of civil or military
authority, civil disturbance, war, strikes or other labour disputes or
disturbances, fire, transportation contingencies, shortage of facilities, fuel,
energy, labour or materials, or laws, regulations, acts or orders of any
governmental agency or official, other catastrophes, or any other circumstance
beyond its reasonable control ("Force Majeure") will be deemed not to be a
breach of this Agreement so long as the party so prevented from complying with
this Agreement has not contributed to such Force Majeure, has used reasonable
efforts to avoid such Force Majeure or to ameliorate its effects, and continues
to take all actions within its power to comply as fully as possible with the
terms of this Agreement. In the event of any such Force Majeure, performance of
the obligations will be deferred until the Force Majeure ceases. This section
will not apply to excuse a failure to make any payment when due.

7.8   COUNTERPARTS

This Agreement may be executed in any number of counterparts with the same
effect as if all parties had signed the same document. All of these counterparts
will for all purposes constitute one agreement, binding on the parties,
notwithstanding that all parties are not signatories to the same counterpart. A
fax transcribed copy or photocopy of this Agreement executed by a party in
counterpart or otherwise will constitute a properly executed, delivered and
binding agreement or counterpart of the executing party.

7.9   WAIVER

No failure or delay on the part of any party in exercising any power or right
under this Agreement will operate as a waiver of such power or right. No single
or partial exercise of any right or power under this Agreement will preclude any
further or other exercise of such right or power. No modification or waiver of
any provision of this Agreement and no consent to any departure by any party
from any provision of this Agreement will be effective until the same is in
writing. Any such waiver or consent will be effective only in the specific
instance and for the specific purpose for which it was given. No notice to or
demand on any party in any circumstances will entitle such party to any other or
further notice or demand in similar or other circumstances.

7.10  FURTHER ASSURANCES

Each of the parties will promptly execute and deliver to the other at the cost
of the other such further documents and assurances and take such further actions
as the other may from time to time request in order to more effectively carry
out the intent and purpose of this Agreement and to establish and protect the
rights, interests and remedies intended to be created in favour of the other.

7.11  ENTIRE AGREEMENT

This Agreement and any other documents and agreements to be delivered pursuant
to this Agreement supersede all previous invitations, proposals, letters,
correspondence, negotiations,

Agreement, other than as expressed in writing in this Agreement. No trade terms
or trade usages are to be incorporated by reference implicitly or otherwise into

writing and signed by each party to
this Agreement.

If any provision of this Agreement or any part of any provision (in this section
called the "Offending Provision") is declared or becomes unenforceable, invalid
or illegal for any reason whatsoever including, without limiting the generality
of the foregoing, a decision by any competent courts, legislation, statutes,
bylaws or regulations or any other requirements having the force of law, then
the remainder of this Agreement will remain in full force and effect as if this
Agreement had been executed without the Offending Provision.

7.14  CURRENCY

Unless otherwise specified all sums of money expressed in this Agreement are in
the lawful money of Canada.

7.15  NUMBER AND GENDER

2.1   As of the IRU Effective Date, Urbanlink shall deliver and provide to
      Customer and Customer shall receive from Urbanlink an exclusive and
      indefeasible right of use of the Capacity on the terms and conditions set
      forth in the Agreement (the "IRU").

2.2   Urbanlink represents and warrants that it possesses those certain rights
      to the Capacity necessary for Urbanlink to deliver the Capacity to
      Customer. Urbanlink shall keep the Capacity free from all claims, liens,
      encumbrances, rights or claims of any third party attributable to
      Urbanlink which have a material adverse effect on the right of Customer to
      use the Capacity as contemplated by this Agreement.

                                   ARTICLE 3
                                    PAYMENT

3.1   In consideration of the grant of the IRU hereunder by Urbanlink to
      Customer, Customer agrees to pay to Urbanlink a fee in the amount of $o
      (the "Purchase Price"). 20% of the Purchase Price is due and payable on
      each of (i) the date of the commencement of the provision of Capacity
      under this Agreement, (ii) the first anniversary of the date of the
      commencement of the provision of Capacity under this Agreement, (iii) the
      second anniversary of the commencement of the provision of Capacity under
      date of this Agreement, (iv) the third anniversary of the date of the
      commencement of the provision of Capacity under this Agreement, and (v)
      the fourth anniversary of the date of the commencement of the provision of
      Capacity under this Agreement.

<PAGE>

3.2   All payments made by Customer hereunder in excess of $100,000 shall be
      made by wire transfer of immediately available funds to the Urbanlink
      Account. Payments of all other amounts by Customer hereunder may be made
      by wire transfer or by company check of immediately available funds
      payable to Urbanlink.

3.3   If Customer fails to make any payment under this Agreement when due, then,
      in addition to such sum and to any other rights and remedies that
      Urbanlink may have, Customer shall pay interest on such unpaid amount at
      the Interest Rate until such sum is paid in full and such interest shall
      accrue both before and after judgment. Notwithstanding the foregoing, no
      interest shall accrue on any payment that is disputed in good faith by
      Customer while such dispute is pending. If such dispute is later resolved
      in favor of Urbanlink, such amount shall bear interest at the Interest
      Rate from the date when due until paid.

3.4   In addition to the amounts payable under Section 3.1, Customer shall be
      responsible to pay directly or reimburse Urbanlink, as requested by
      Urbanlink, for all other sums, costs, fees and expenses that are required
      to be paid under this Agreement. Urbanlink will invoice Customer for all
      sums, costs, fees and expenses, owed by Customer to Urbanlink, and
      Customer shall pay such invoices within 30 days of the invoice date,
      except for the Purchase Price which shall be paid in accordance with
      Section 3.1.

3.5   All payments made by Customer under this Agreement shall be made without
      any deduction or withholding for or on account of any Imposition. If
      Customer is required by law to make any deduction or withholding from any
      payment due Urbanlink, then, notwithstanding anything to the contrary
      contained in this Agreement, the gross amount payable by Customer to
      Urbanlink shall be increased so that after any such deduction or
      withholding for such Impositions or any additional deduction or
      withholding on account of any Imposition caused by such additional
      gross-up payment, the net amount received by Urbanlink will not be less
      than what Urbanlink would have received had no deduction or withholding
      been required.

                                   ARTICLE 4
                        ACCEPTANCE TESTING AND DELIVERY

4.1   When Urbanlink has determined that the Capacity is operating substantially
      in conformity with the applicable service levels set forth in Exhibit B
      (the "Service Level Agreement"), Urbanlink shall promptly provide Customer
      written notice of the same (a "Completion Notice"). Each Completion Notice
      shall set forth the date upon which Urbanlink will commence delivery of
      the Capacity to Customer provided that all payments due under this
      Agreement have been paid in full.

4.2   Within ten (10) days of receipt of a Completion Notice, Customer shall
      provide Urbanlink a written notice accepting or rejecting the Capacity,
      specifying in reasonable detail, if rejected, the defect or failure in the
      Capacity. If Customer fails to notify Urbanlink of its acceptance or
      rejection of the Completion Notice within ten (10) days following
      Customer's receipt of the same, Customer shall be deemed to have accepted
      such Capacity. Any use of Capacity by Customer other than for testing
      purposes shall be


                                      -4-
<PAGE>

      deemed to constitute acceptance of the Capacity. The date of such notice
      of acceptance or deemed acceptance of the Capacity shall be the
      "Acceptance Date". In the event of any good-faith rejection by Customer,
      Urbanlink shall take such action as reasonably necessary, and as
      expeditiously as practicable, to correct or cure such defect or failure.
      Customer shall in no event be entitled to commence use of the Capacity
      until after Urbanlink has received payment in full.

4.3   Provided Urbanlink first obtains Customer's written consent, which consent
      may not be unreasonably withheld or delayed, Urbanlink may substitute,
      change or reconfigure the telecommunications equipment and facilities used
      in providing the Capacity as long as the quality and type of Capacity is
      not impaired or changed. In such event, the Parties shall work together in
      good faith to minimize any disruption of service in connection with such
      substitution, change or reconfiguration.

                                   ARTICLE 5
                                      TERM

5.1   The IRU shall become effective on the first day when both the Acceptance
      Date has occurred, and Urbanlink has received payment in full of the
      Purchase Price (the "IRU Effective Date") and the IRU shall extend until
      the expiry of the Underlying Rights in respect of that part of the
      Urbanlink System that contains the specific fibres on which the Capacity
      is being provided by Urbanlink under the terms of this Agreement (the
      "Term"); provided that if the Underlying Rights for the routes described
      on Exhibit A expire on different dates, the Term shall expire on the
      expiry on the last of such Underlying Rights to expire; and provided
      further that if the Underlying Rights expire for some routes described on
      Exhibit "A" prior to the expiry of the Term, the IRU shall then expire and
      terminate for such route and the rights of the Customer to use the
      Capacity in respect of such route shall cease.

5.2   At the expiration or other termination of this Agreement, the IRU shall
      immediately terminate, and all rights of Customer to use the Capacity
      shall cease. The expiration or termination of this Agreement shall not
      relieve Customer from any liabilities arising prior to such termination.

5.3   If at any time Customer, in its absolute discretion, determines not to
      retain the IRU, Customer shall have the right to abandon the IRU by
      written notice to Urbanlink. In the case of such abandonment, this
      Agreement shall terminate and Customer shall not be entitled to a refund
      of any of the consideration paid. Upon such termination, all fees, costs
      and other expenses with respect to this Agreement shall be immediately due
      and payable to Urbanlink by Customer.

                                   ARTICLE 6
                                INTERCONNECTION

6.1   To the extent technically feasible, as determined by Urbanlink and the
      Customer acting reasonably and in good faith, Urbanlink shall permit
      Customer to interconnect its communications system with the Capacity
      within Urbanlink's facilities or structures at


                                      -5-
<PAGE>

      the Endpoints or at such other location as may be agreed from time to
      time, acting reasonably. Urbanlink shall perform all work with respect to
      such interconnection as it relates to the Urbanlink System or any other
      facilities, equipment or structures of Urbanlink or its Affiliates.
      Customer shall pay Urbanlink for its Costs to perform such work plus a
      management fee equal to fifteen percent (15%) of such Costs within thirty
      (30) days of receiving an invoice therefor. Nothing contained in this
      Agreement shall obligate Customer to obtain or facilitate the provisioning
      of local access with respect to the Capacity.

                                   ARTICLE 7
                             MAINTENANCE AND REPAIR

7.1   From and after the IRU Effective Date, Urbanlink shall maintain the
      Capacity in good working order and in accordance with industry standards.

7.2   In consideration of the maintenance services, Customer shall pay Urbanlink
      the operations and maintenance fees (the "O&M Fees") with respect to the
      city pairs listed below (subject to adjustment as provided in Section 7.3)
      equal to a monthly amount determined by the Customer and Urbanlink, acting
      reasonably, each year as being a reasonable allocation of the costs of
      Urbanlink to operate, repair and maintain the Urbanlink System.

7.3   The O&M Fee shall be increased annually, beginning with the first
      anniversary of the Effective Date, by the increase, if any, in the
      Consumer Price Index - Canada - All Items ("CPI") published by Statistics
      Canada for the twelve (12) month period ending three months prior to such
      anniversary of the effective date. In the event that Statistics Canada no
      longer publishes the CPI, Customer and Urbanlink shall together, acting
      reasonably and in good faith, designate the statistical index they
      consider most appropriate for adjustments to a fee and, from the date the
      CPI ceased to be published, such index shall be used to make adjustments
      in a fee under this provision.

7.4   Customer shall have no right to physically access in any manner the
      Urbanlink System or any components thereof.

                                   ARTICLE 8
                              USE OF THE CAPACITY

8.1   Customer represents, warrants and covenants that it will use the Capacity
      in compliance with and subject to all applicable government codes,
      ordinances, laws, rules and regulations and will require its customers
      that purchase telecommunication services, circuits or capacity from the
      Customer or its Affiliates do the same. Customer shall not use its systems
      in a way that interferes in any way with or adversely affects the use of
      the Urbanlink System or any other Person using the Urbanlink System or
      Capacity thereon. The parties acknowledge that the Urbanlink System
      includes or will include other customers and participants, including
      without limitation other owners and users of telecommunication systems.

8.2   Notwithstanding anything to the contrary contained herein, Customer shall
      secure, prior to the IRU Effective Date, and maintain in full force and
      effect during the Term, any and all necessary consents, franchises or
      similar approvals from all governmental and other authorities which are
      necessary or required to be obtained by Customer for Urbanlink to grant
      the IRU to Customer and for the use and operation of the Capacity by
      Customer.

8.3   Subject to Article 18, Urbanlink shall have no right to sell, lease,
      transfer or use the Capacity or any portion thereof.

8.4   Customer and Urbanlink each agree to cooperate with and support the other
      in complying with any requirements applicable to their respective rights
      and obligations hereunder. Customer and Urbanlink shall promptly notify
      each other of any matters pertaining to, or the occurrence (or impending
      occurrence) of, any event which would be reasonably likely to give rise to
      any damage or impending damage to or loss of the Urbanlink System or
      Capacity that are known to such Party.

                                INDEMNIFICATION

      and their employees, officers and directors, from and against, and assumes
      liability for:

      (a)   All suits, actions, damages or claims of any character (i) brought

            received or sustained by any persons or property which in whole or
            in part arise on account of the acts or negligent omissions of
            Urbanlink in the performance of construction or maintenance of the
            Urbanlink System or the provision of the Capacity or the performance
            of its obligations under this Agreement; and (ii) brought against
            Customer or its Affiliates under the workers compensation laws,
            except to the extent caused by the negligence or wilful misconduct
            of the parties indemnified hereunder.

9.2   Subject to the provisions of Article 10, Customer hereby agrees to
      indemnify, defend, protect and hold harmless Urbanlink, and its employees,
      officers and directors, from and against, and assumes liability for:

      (a)   All suits, actions, damages or claims of any character (i) brought
            against Urbanlink or its Affiliates because of any injuries or
            damage received or sustained by any persons or property which in
            whole or in part arise on account of the acts or negligent omissions
            of Customer in the performance of its obligations under this
            Agreement; (ii) brought against Urbanlink or its Affiliates under
            workers compensation laws, except to the extent caused by the
            negligence or wilful misconduct of the parties indemnified

            because of any damage arising out of or resulting from Customer's
            use of the Capacity and conduct of its business, including the
            content

            through or using the Capacity.

9.3   Nothing contained herein shall operate as a limitation on the right of
      either Party hereto to bring an action for damages against any third
      party, including indirect, special or consequential damages, based on any
      acts or negligent omissions of such third party as such acts or omissions
      may affect the construction, operation or use of the Capacity or the
      Urbanlink System; provided, however, that each Party hereto shall assign
      such rights or claims, execute such documents and do whatever else may be
      reasonably necessary to enable the other Party to pursue any such action
      against such third party.

      CONSEQUENTIAL COSTS, LIABILITIES OR DAMAGES, WHETHER FORESEEABLE OR NOT,
      ARISING OUT OF, OR IN CONNECTION WITH, SUCH PARTY'S PERFORMANCE OF ITS

      Customer's sole rights and remedies with respect to any defect in or
      failure of the Capacity to perform in accordance with the Service Level

      Agreement.

10.3  The Parties expressly agree that no claim for losses or damages whatsoever
      in connection with this Agreement shall be made more than two years after
      the date that the event giving rise to such claim is known or reasonably
      should have been known to the Party making such claim.

                                   INSURANCE

11.1  Throughout the term of the IRU, each Party shall procure and maintain in
      force, at its own expense:

      (a)   General Liability insurance with a minimum limit of $5,000,000,
            including coverage for contractual liability, non-owned auto
            liability, Owner's & Contractor's protective liability and products
            and completed operations liability. Such policy shall be written on
            an occurrence basis and shall contain a cross liability or
            severability of interest clause;

      (b)   Workers' Compensation insurance covering all employees engaged in
            the work in accordance with the statutory requirements of the
            county, state, province or


                                      -8-

            territory or other governmental body having jurisdiction over such
            employees.

      (c)   Employers' Liability insurance with a minimum limit of $5,000,000,
            covering all employees engaged in the work;

      (d)   Automobile liability insurance with a minimum limit of $5,000,000,
            covering all motor vehicles owned, operated and/or licensed
            (including owned, leased, or hired units);

      (e)   "All Risks" Property insurance on a replacement cost basis, for
            damage to the system and associated property, with deductibles and
            limits in such amounts as would from time to time be carried by a
            prudent owner considering the property insured; and

      (f)   any other insurance coverages specifically required of such Party
            pursuant to right-of-way agreements with railroads or other third
            parties.

      (g)   Both parties shall require any contractors engaged in construction
            or maintenance of the system to maintain insurance in accordance
            with the provisions of this Article 11.1.

11.2  Both parties expressly acknowledge that a Party shall be deemed to be in
      compliance with the provisions of this Article if it maintains a
      self-insurance program providing for a retention of up to $1,000,000.
      Unless otherwise agreed, Customer's and Urbanlink's insurance policies
      shall be obtained and maintained with companies rated "A" or better by
      BEST'S KEY RATING GUIDE and each Party shall provide the other with an
      insurance certificate confirming compliance with this requirement for each
      policy providing such required coverage.

11.3  If either Party fails to obtain the required insurance or fails to obtain
      the required certificates from any contractor and a claim is made or
      suffered, such Party shall indemnify and hold harmless the other Party
      from any and all claims for which the required insurance would have
      provided coverage. Further, in the event of any such failure which
      continues after seven (7) days' written notice thereof by the other Party,
      such other Party may, but shall not be obligated to, obtain such insurance
      and will have the right to be reimbursed for the cost of such insurance by
      the Party failing to obtain such insurance.

11.4  In the event coverage is denied or reimbursement of a properly presented
      claim is disputed by the carrier for insurance provided above, the Party
      carrying such coverage shall make good-faith efforts to pursue such claim
      with its carrier.

11.5  Each party shall upon request from the other provide evidence of the
      insurances which it is obligated to maintain under clause 11.1. All
      insurance policies shall contain a provision that coverage cannot be
      cancelled or materially reduced until the insurer has provided at least 30
      days written notice to the non-insuring party.

      require insurers to amend all such policies to include a waiver of
      subrogation in favor of the other party.

      as otherwise required by law or in any legal or arbitration proceeding

      with prompt prior written notice of such request or requirement so that

      compliance with this Section. The Party whose consent to disclose
      information is requested shall respond to such request, in writing, within
      five (5) working days of the request by either authorizing the disclosure
      or advising of its election to seek a protective order, or if such Party
      fails to respond within the prescribed period the disclosure shall be

      any copyrights, inventions, or patents now or hereafter owned or
      controlled by Urbanlink.

13.3  Upon termination of this Agreement for any reason or upon request of
      Urbanlink, Customer shall return all Confidential Information, together

      Urbanlink, use any trademark or trade name of Urbanlink or refer to the
      subject matter of this Agreement or Urbanlink in any promotional activity

            after notice specifying such breach, or

      (b)   in the case of any other material breach of this Agreement, a Party
            fails to cure such material breach within thirty (30) days after
            notice specifying such breach, provided that if the breach is of a
            nature that cannot be cured within thirty (30) days, a default shall
            not have occurred so long as the breaching Party has commenced to
            cure within said time period and thereafter diligently pursues such
            cure to completion.

14.2  If the default consists of a failure of Customer to pay to Urbanlink any
      part of the Purchase Price, Urbanlink may terminate any and all of its
      obligations under this Agreement, and apply any and all amounts previously
      paid by Customer hereunder toward the payment of any other amounts then or
      thereafter payable by Customer under this Agreement or suspend the

      its sole discretion, to correct the default; and (b) pursue any legal
      remedies it may have under applicable law or principles of equity,
      including specific performance.

14.3  A waiver by either Party at any time of any of its rights as to anything
      herein contained shall not be deemed to be a waiver of any breach of
      covenant or other matter subsequently occurring.

14.4  Notwithstanding anything contained in this Agreement to the contrary,
      Customer's sole and exclusive remedy for any failure by Urbanlink to
      deliver the Capacity in accordance with this Agreement shall be limited to

      the expiration of the Term or other termination of this Agreement, the IRU
      shall immediately terminate and all rights of Customer to use the Capacity
      shall cease, all such rights shall revert to Urbanlink, and Urbanlink
      shall owe Customer no further duties, obligations or consideration.

      of either Party that have arisen before the date of termination or
      expiration.

                              FORCE MAJEURE EVENTS

16.1  Neither Party shall be in default under this Agreement if and to the
      extent that any failure or delay in such Party's performance of one or
      more of its obligations hereunder is caused by any of the following

      shall be excused and extended for and during the period of any such delay:
      act of God; fire; flood; fiber, cable, equipment or other material or
      component failures, shortages or unavailability or other delay in delivery

17.1  Application. The Parties will attempt to resolve any dispute arising out
      of this Agreement promptly through discussions at the operational level.
      In the event a resolution is not achieved, the disputing Party shall
      provide the other Party with written notice of the same and the Parties
      shall attempt to resolve such dispute between senior executives who have
      the authority to settle such dispute. If the Parties fail to resolve such
      dispute within thirty (30) days of the non-disputing Party's receipt of
      the written notice, either Party may seek arbitration as set forth below.

17.2  Arbitration. All disputes arising out of or in connection with this
      Agreement, or in respect of any defined legal relationship associated
      therewith or derived therefrom (including, without limitation, any claim,

      fraud, misrepresentation or other legal theory, related directly or
      indirectly to this Agreement, and whenever brought and whether between the
      parties to this Agreement or between one of the parties to this Agreement
      and the employees, agents or affiliated businesses of the other Party),
      shall be referred to and finally resolved by arbitration under the Rules
      of the British Columbia International Commercial Arbitration Centre. The

      Commercial Arbitration Centre. The case shall be administered by the
      British Columbia International Commercial Arbitration Centre in accordance
      with its "Procedures for Cases Under the BCICAC Rules". The place of

      arbitrators shall be one.

17.3  Discovery. There shall be no discovery other than the exchange of
      information that is provided to the arbitrator by the parties. Each Party
      shall bear its own costs and attorneys' fees, and the parties shall share
      equally the fees and expenses of the arbitrator. The arbitrator's decision
      and award shall be final and binding, and judgment on the award rendered
      by the arbitrator may be entered in any court having jurisdiction thereof.

17.4  Enforcement. If any Party files a judicial or administrative action
      asserting claims subject to arbitration as prescribed herein, and another
      Party successfully stays such action or compels arbitration of said
      claims, the Party filing said action shall pay the other Party's costs and
      expenses incurred in seeking such stay or compelling arbitration,
      including reasonable attorneys' fees.

                      ASSIGNMENT AND TRANSFER RESTRICTIONS

18.1  Except as provided in Section 18.2, Customer may not transfer or assign
      all or any part of its interest under this Agreement, or delegate any
      duties, burdens, or obligations arising hereunder, without Urbanlink's
      consent, which consent shall not be unreasonably withheld or delayed. A
      transfer or assignment in violation of this Article 18 shall constitute a
      material breach of this Agreement. If any such consent is given, Customer
      nevertheless shall remain fully and primarily liable for all obligations
      under this Agreement. Notwithstanding anything to the contrary contained
      in this Article 18,

      Assignee" shall mean (a) any Affiliate of Customer, (b) any Person that
      purchases all or substantially all of the assets of Customer, or any other
      Person formed by or surviving the merger or consolidation of Customer and

      assigned as collateral security for any indebtedness of Customer or any
      Affiliate of Customer, provided that such collateral assignment is subject
      to the terms of this Agreement. Upon any assignment to a Permitted
      Assignee, the assignor shall remain responsible for performance under this
      Agreement. Any Permitted Assignee pursuant to subparagraph (a) or (b)
      above shall expressly assume all obligations and liabilities with respect
      to the Agreement which arise after the effective date of assignment or
      transfer, prior to or upon the effectiveness of such assignment and, in

      liabilities with respect to the Agreement which arise thereafter.

18.3  Except as provided in Section 18.4, Urbanlink may not transfer or assign
      all or any part of its interest under this Agreement, or delegate any
      duties, burdens, or obligations arising hereunder, without Customer's
      consent, which consent shall not be unreasonably withheld or delayed. A
      transfer or assignment in violation of this Article 18 shall constitute a
      material breach of this Agreement. If any such consent is given, Urbanlink
      nevertheless shall remain fully and primarily liable for all obligations
      under this Agreement.

      Permitted Assignee. As used in this Section 18.4, the term "Permitted

      this Agreement is assigned as collateral security for any indebtedness
      Urbanlink or any Affiliate of Urbanlink, provided that such collateral
      assignment is subject to the terms of this Agreement. Upon any assignment
      to a Permitted Assignee, the assignor shall remain responsible for
      performance under this Agreement. Any Permitted Assignee pursuant to
      subparagraph (a) or (b) above shall expressly assume all obligations and
      liabilities with respect to the Agreement which arise after the effective
      date of assignment or transfer, prior to or upon the effectiveness of such
      assignment and, in the case of an assignment as provided in subparagraph
      (c) of this Section 18.4, in the event the institutional lender exercises
      its rights with respect to this Agreement it shall expressly assume all
      obligations and liabilities with respect to the Agreement which arise

      and obligations under this Agreement, shall be binding on and shall inure
      to the benefit of the Parties hereto and each of their respective
      permitted successors and assigns.

20.2  Waiver. The failure of either Party hereto to enforce any of the
      provisions of this Agreement, or the waiver thereof in any instance, shall
      not be construed as a general waiver or relinquishment on its part of any
      such provision, but the same shall nevertheless be and remain in full
      force and effect.

20.3  Governing Law. This Agreement shall be governed by and construed in
      accordance with the laws of the Province of British Columbia and the
      federal law of Canada applicable therein, without giving effect to its
      principles of conflicts of laws. Subject to Article 17, any litigation
      based hereon, or arising out of or in connection with a default by either

      and maintained exclusively in the courts of the Province of British
      Columbia, in Vancouver, British Columbia, and each Party hereby
      irrevocably submits to the jurisdiction of such courts

            similar or dissimilar to those listed, as the context reasonably
            requires.

      (b)   Except as set forth to the contrary herein, any right or remedy of

      provisions of any Exhibit hereto are inconsistent with the express terms
      of this Agreement, the terms of this Agreement shall prevail. This
      Agreement may only be modified or supplemented by an instrument in writing
      executed by each Party and delivered to the Party relying on the writing.

2.1   As of the IRU Effective Date, Urbanlink shall deliver and provide to
      Customer and Customer shall receive from Urbanlink an exclusive and
      indefeasible right of use of the Capacity on the terms and conditions set
      forth in the Agreement (the "IRU").

2.2   Urbanlink represents and warrants that it possesses those certain rights
      to the Capacity necessary for Urbanlink to deliver the Capacity to
      Customer. Urbanlink shall keep the Capacity free from all claims, liens,
      encumbrances, rights or claims of any third party attributable to
      Urbanlink which have a material adverse effect on the right of Customer to
      use the Capacity as contemplated by this Agreement.

                                   ARTICLE 3
                                    PAYMENT

3.1   In consideration of the grant of the IRU hereunder by Urbanlink to
      Customer, Customer agrees to pay to Urbanlink a fee in an amount (the
      "Specified Amount") as agreed between the Customer and Urbanlink per
      strand per route kilometer multiplied by the number of strand route
      kilometers (the "Purchase Price") (reduced for the strand route kilometers
      between Endpoints Edmonton and Toronto, by a fraction, the numerator of
      which is the capacity to be provided on such routes, and the denominator
      of which is the capacity to be provided on the other routes). 20% of the
      Purchase Price is due and payable on each of (i) the date of the
      commencement of the provision of Capacity under


                                      -3-
<PAGE>

      this Agreement, (ii) the first anniversary of the date of the commencement
      of the provision of Capacity under this Agreement, (iii) the second
      anniversary of the commencement of the provision of Capacity under date of
      this Agreement, (iv) the third anniversary of the date of the commencement
      of the provision of Capacity under this Agreement, and (v) the fourth
      anniversary of the date of the commencement of the provision of Capacity
      under this Agreement.

3.2   All payments made by Customer hereunder in excess of $100,000 shall be
      made by wire transfer of immediately available funds to the Urbanlink
      Account. Payments of all other amounts by Customer hereunder may be made
      by wire transfer or by company check of immediately available funds
      payable to Urbanlink.

3.3   If Customer fails to make any payment under this Agreement when due, then,
      in addition to such sum and to any other rights and remedies that
      Urbanlink may have, Customer shall pay interest on such unpaid amount at
      the Interest Rate until such sum is paid in full and such interest shall
      accrue both before and after judgment. Notwithstanding the foregoing, no
      interest shall accrue on any payment that is disputed in good faith by
      Customer while such dispute is pending. If such dispute is later resolved
      in favor of Urbanlink, such amount shall bear interest at the Interest
      Rate from the date when due until paid.

3.4   In addition to the amounts payable under Section 3.1, Customer shall be
      responsible to pay directly or reimburse Urbanlink, as requested by
      Urbanlink, for all other sums, costs, fees and expenses that are required
      to be paid under this Agreement. Urbanlink will invoice Customer for all
      sums, costs, fees and expenses, owed by Customer to Urbanlink, and
      Customer shall pay such invoices within 30 days of the invoice date,
      except for the Purchase Price which shall be paid in accordance with
      Section 3.1.

3.5   All payments made by Customer under this Agreement shall be made without
      any deduction or withholding for or on account of any Imposition. If
      Customer is required by law to make any deduction or withholding from any
      payment due Urbanlink, then, notwithstanding anything to the contrary
      contained in this Agreement, the gross amount payable by Customer to
      Urbanlink shall be increased so that after any such deduction or
      withholding for such Impositions or any additional deduction or
      withholding on account of any Imposition caused by such additional
      gross-up payment, the net amount received by Urbanlink will not be less
      than what Urbanlink would have received had no deduction or withholding
      been required.

                                   ARTICLE 4
                        ACCEPTANCE TESTING AND DELIVERY

4.1   When Urbanlink has determined that the Capacity is operating substantially
      in conformity with the applicable service levels set forth in Exhibit B
      (the "Service Level Agreement"), Urbanlink shall promptly provide Customer
      written notice of the same (a "Completion Notice"). Each Completion Notice
      shall set forth the date upon which Urbanlink will commence delivery of
      the Capacity to Customer provided that all payments due under this
      Agreement have been paid in full.


                                      -4-
<PAGE>

4.2   Within ten (10) days of receipt of a Completion Notice, Customer shall
      provide Urbanlink a written notice accepting or rejecting the Capacity,
      specifying in reasonable detail, if rejected, the defect or failure in the
      Capacity. If Customer fails to notify Urbanlink of its acceptance or
      rejection of the Completion Notice within ten (10) days following
      Customer's receipt of the same, Customer shall be deemed to have accepted
      such Capacity. Any use of Capacity by Customer other than for testing
      purposes shall be deemed to constitute acceptance of the Capacity. The
      date of such notice of acceptance or deemed acceptance of the Capacity
      shall be the "Acceptance Date". In the event of any good-faith rejection
      by Customer, Urbanlink shall take such action as reasonably necessary, and
      as expeditiously as practicable, to correct or cure such defect or
      failure. Customer shall in no event be entitled to commence use of the
      Capacity until after Urbanlink has received payment in full.

4.3   Provided Urbanlink first obtains Customer's written consent, which consent
      may not be unreasonably withheld or delayed, Urbanlink may substitute,
      change or reconfigure the telecommunications equipment and facilities used
      in providing the Capacity as long as the quality and type of Capacity is
      not impaired or changed. In such event, the Parties shall work together in
      good faith to minimize any disruption of service in connection with such
      substitution, change or reconfiguration.

                                   ARTICLE 5
                                      TERM

5.1   The IRU shall become effective on the first day when both the Acceptance
      Date has occurred, and Urbanlink has received payment in full of the
      Purchase Price (the "IRU Effective Date") and the IRU shall extend until
      the expiry of the Underlying Rights in respect of that part of the
      Urbanlink System that contains the specific fibres on which the Capacity
      is being provided by Urbanlink under the terms of this Agreement (the
      "Term"); provided that if the Underlying Rights for the routes described
      on Exhibit A expire on different dates, the Term shall expire on the
      expiry on the last of such Underlying Rights to expire; and provided
      further that if the Underlying Rights expire for some routes described on
      Exhibit "A" prior to the expiry of the Term, the IRU shall then expire and
      terminate for such route and the rights of the Customer to use the
      Capacity in respect of such route shall cease.

5.2   At the expiration or other termination of this Agreement, the IRU shall
      immediately terminate, and all rights of Customer to use the Capacity
      shall cease. The expiration or termination of this Agreement shall not
      relieve Customer from any liabilities arising prior to such termination.

5.3   If at any time Customer, in its absolute discretion, determines not to
      retain the IRU, Customer shall have the right to abandon the IRU by
      written notice to Urbanlink. In the case of such abandonment, this
      Agreement shall terminate and Customer shall not be entitled to a refund
      of any of the consideration paid. Upon such termination, all fees, costs
      and other expenses with respect to this Agreement shall be immediately due
      and payable to Urbanlink by Customer.

                                   ARTICLE 6
                                INTERCONNECTION

6.1   To the extent technically feasible, as determined by Urbanlink and the
      Customer acting reasonably and in good faith, Urbanlink shall permit
      Customer to interconnect its communications system with the Capacity
      within Urbanlink's facilities or structures at the Endpoints or at such
      other location as may be agreed from time to time, acting reasonably.
      Urbanlink shall perform all work with respect to such interconnection as
      it relates to the Urbanlink System or any other facilities, equipment or
      structures of Urbanlink or its Affiliates. Customer shall pay Urbanlink
      for its Costs to perform such work plus a management fee equal to fifteen
      percent (15%) of such Costs within thirty (30) days of receiving an
      invoice therefor. Nothing contained in this Agreement shall obligate
      Customer to obtain or facilitate the provisioning of local access with
      respect to the Capacity.

                                   ARTICLE 7
                             MAINTENANCE AND REPAIR

7.1   From and after the IRU Effective Date, Urbanlink shall maintain the
      Capacity in good working order and in accordance with industry standards.

7.2   In consideration of the maintenance services, Customer shall pay Urbanlink
      the operations and maintenance fees (the "O&M Fees") with respect to the
      city pairs listed below (subject to adjustment as provided in Section 7.3)
      equal to a monthly amount determined by the Customer and Urbanlink, acting
      reasonably, each year as being a reasonable allocation of the costs of
      Urbanlink to operate, repair and maintain the Urbanlink System.

7.3   The O&M Fee shall be increased annually, beginning with the first
      anniversary of the Effective Date, by the increase, if any, in the
      Consumer Price Index - Canada - All Items ("CPI") published by Statistics
      Canada for the twelve (12) month period ending three months prior to such
      anniversary of the effective date. In the event that Statistics Canada no
      longer publishes the CPI, Customer and Urbanlink shall together, acting
      reasonably and in good faith, designate the statistical index they
      consider most appropriate for adjustments to a fee and, from the date the
      CPI ceased to be published, such index shall be used to make adjustments
      in a fee under this provision.

7.4   Customer shall have no right to physically access in any manner the
      Urbanlink System or any components thereof.

                                   ARTICLE 8
                              USE OF THE CAPACITY

8.1   Customer represents, warrants and covenants that it will use the Capacity
      in compliance with and subject to all applicable government codes,
      ordinances, laws, rules and regulations and will require its customers
      that purchase telecommunication services, circuits or capacity from the
      Customer or its Affiliates do the same. Customer shall not use its systems
      in a way that interferes in any way with or adversely affects the use of
      the


                                      -6-
<PAGE>

      Urbanlink System or any other Person using the Urbanlink System or
      Capacity thereon. The parties acknowledge that the Urbanlink System
      includes or will include other customers and participants, including
      without limitation, other owners and users of telecommunication systems.

8.2   Notwithstanding anything to the contrary contained herein, Customer shall
      secure, prior to the IRU Effective Date, and maintain in full force and
      effect during the Term, any and all necessary consents, franchises or
      similar approvals from all governmental and other authorities which are
      necessary or required to be obtained by Customer for Urbanlink to grant
      the IRU to Customer and for the use and operation of the Capacity by
      Customer.

      transfer or use the Capacity or any portion thereof.

8.4   Customer and Urbanlink each agree to cooperate with and support the other
      in complying with any requirements applicable to their respective rights
      and obligations hereunder. Customer and Urbanlink shall promptly notify
      each other of any matters pertaining to, or the occurrence (or impending
      occurrence) of, any event which would be reasonably likely to give rise to
      any damage or impending damage to or loss of the Urbanlink System or
      Capacity that are known to such Party.

      liability for:

      (a)   All suits, actions, damages or claims of any character (i) brought

            received or sustained by any persons or property which in whole or
            in part arise on account of the acts or negligent omissions of
            Urbanlink in the performance of construction or maintenance of the
            Urbanlink System or the provision of the Capacity or the performance
            of its obligations under this Agreement; and (ii) brought against

<PAGE>

            misconduct of the parties indemnified hereunder; and (iii) brought

            of its business, including the content of any video, voice or data
            carried by Customer or its customers through or using the Capacity.

9.3   Nothing contained herein shall operate as a limitation on the right of
      either Party hereto to bring an action for damages against any third
      party, including indirect, special or consequential damages, based on any
      acts or negligent omissions of such third party as such acts or omissions
      may affect the construction, operation or use of the Capacity or the
      Urbanlink System; provided, however, that each Party hereto shall assign
      such rights or claims, execute such documents and do whatever else may be
      reasonably necessary to enable the other Party to pursue any such action
      against such third party.

      (f)   any other insurance coverages specifically required of such Party
            pursuant to right-of-way agreements with railroads or other third

            with the provisions of this Article 11.1.

11.2  Both parties expressly acknowledge that a Party shall be deemed to be in
      compliance with the provisions of this Article if it maintains a
      self-insurance program providing for a retention of up to $1,000,000.
      Unless otherwise agreed, Customer's and Urbanlink's insurance policies
      shall be obtained and maintained with companies rated "A" or better by

      days written notice to the non-insuring party.

      (a)   in the case of a failure to pay any amount when due under this

            after notice specifying such breach, or

      (b)   in the case of any other material breach of this Agreement, a Party
            fails to cure such material breach within thirty (30) days after
            notice specifying such breach, provided that if the breach is of a
            nature that cannot be cured within thirty (30) days, a default shall
            not have occurred so long as the breaching Party has commenced to
            cure within said time period and thereafter diligently pursues such
            cure to completion.

14.2  If the default consists of a failure of Customer to pay to Urbanlink any
      part of the Purchase Price, Urbanlink may terminate any and all of its
      obligations under this Agreement, and apply any and all amounts previously
      paid by Customer hereunder toward the payment of any other amounts then or
      thereafter payable by Customer under this Agreement or suspend the
      provisioning of the Capacity hereunder. In the event of any other default

      (a)   take such actions as it determines, in its sole discretion, to
            correct the default; and

      (b)   pursue any legal remedies it may have under applicable law or
            principles of equity, including specific performance.

14.3  A waiver by either Party at any time of any of its rights as to anything
      herein contained shall not be deemed to be a waiver of any breach of
      covenant or other matter subsequently occurring.

14.4  Notwithstanding anything contained in this Agreement to the contrary,
      Customer's sole and exclusive remedy for any failure by Urbanlink to
      deliver the Capacity in accordance with this Agreement shall be limited to

      of either Party that have arisen before the date of termination or
      expiration.

16.1  Neither Party shall be in default under this Agreement if and to the
      extent that any failure or delay in such Party's performance of one or
      more of its obligations hereunder is caused by any of the following

      shall be excused and extended for and during the period of any such delay:
      act of God; fire; flood; fiber, cable, equipment or other material or
      component failures, shortages or unavailability or other delay in delivery

18.1  Except as provided in Section 18.2, Customer may not transfer or assign
      all or any part of its interest under this Agreement, or delegate any
      duties, burdens, or obligations arising hereunder, without Urbanlink's
      consent, which consent shall not be unreasonably withheld or delayed. A
      transfer or assignment in violation of this Article 18 shall constitute a
      material breach of this Agreement. If any such consent is given, Customer

      assigned as collateral security for any indebtedness of Customer or any
      Affiliate of Customer, provided that such collateral assignment is subject
      to the terms of this Agreement. Upon any assignment to a Permitted
      Assignee, the assignor shall remain responsible for performance under this
      Agreement. Any Permitted Assignee pursuant to subparagraph (a) or (b)
      above shall expressly assume all obligations and liabilities with respect
      to the Agreement which arise after the effective date of assignment or

      this Agreement is assigned as collateral security for any indebtedness
      Urbanlink or any Affiliate of Urbanlink, provided that such collateral
      assignment is subject to the terms of this Agreement. Upon any assignment
      to a Permitted Assignee, the assignor shall remain responsible for
      performance under this Agreement. Any Permitted Assignee pursuant to
      subparagraph (a) or (b) above shall expressly assume all obligations and
      liabilities with respect to the Agreement which arise after the effective
      date of assignment or transfer, prior to or upon the effectiveness of such
      assignment and, in the case of an assignment as provided in subparagraph
      (c) of this Section 18.4, in the event the institutional lender exercises
      its rights with respect to this Agreement it shall expressly assume all
      obligations and liabilities with respect to the Agreement which arise

7.5   ASSIGNMENT

      (a)   This Agreement is not assignable by Urbanlink in whole or in part
            without the prior written consent of 360, such consent not to be
            unreasonably delayed. This Agreement is not assignable by 360 or
            Services without the prior written consent of Urbanlink, such
            consent not to be unreasonably delayed. Any attempt by any party to
            assign any of the rights or to delegate any of the duties or
            obligations of this Agreement without such prior written consent is
            void.

      (b)   Notwithstanding the foregoing, the interests of any party may be
            assigned by such party to an Affiliate, provided that such Affiliate
            delivers to the other parties a written undertaking to be bound by
            the provisions of this Agreement in all respects and to the same
            extent as the assignor is bound and provided further that the
            assignor will continue to be bound by all the obligations hereunder
            as if such assignment had not occurred and shall perform such
            obligations to the extent that such Affiliate fails to do so.


                                      -8-
<PAGE>

      (c)   Notwithstanding the foregoing, the interests of a party under this
            Agreement (including, without limitation, in the case of Urbanlink,
            the right to receive any and all amounts payable to Urbanlink under
            this Agreement) may be assigned by such party by way of collateral
            security to a lender without the consent of the other parties,
            provided however that any such lender agrees in writing that:

            (i)   the rights and interest of the lender are subject to the
                  rights and interests of the parties other than the assignor
                  under this Agreement;

            (ii)  prior to realizing on such collateral security it will provide
                  notice to the other parties giving them the opportunity to
                  cure the default; and

            (iii) should such security be realized with the result that the
                  title or interest of the assignor, as the case may be, is
                  vested in an assignee, acquirer or other successor in title or
                  interest (including the lender if such is the case)
                  ("Successor"), then the lender will cause such Successor to
                  enter into a written agreement with the other parties to be
                  bound by the provisions of this Agreement in all respects and
                  to the same extent as the assignor was bound and this from the
                  date the title or interest is transferred and provided further
                  that the assignor will continue to be bound by all the
                  obligations under this Agreement as if such transfer of title
                  or interest had not occurred and will perform such obligations
                  to the extent that the Successor fails to do so.

7.6   FORCE MAJEURE

The failure or delay of any party to this Agreement to perform any obligation
under this Agreement solely by reason of acts of God, acts of civil or military
authority, civil disturbance, war, strikes or other labour disputes or
disturbances, fire, transportation contingencies, shortage of facilities, fuel,
energy, labour or materials, or laws, regulations, acts or orders of any
governmental agency or official, other catastrophes, or any other circumstance
beyond its reasonable control ("Force Majeure") will be deemed not to be a
breach of this Agreement so long as the party so prevented from complying with
this Agreement has not contributed to such Force Majeure, has used reasonable
efforts to avoid such Force Majeure or to ameliorate its effects, and continues
to take all actions within its power to comply as fully as possible with the
terms of this Agreement. In the event of any such Force Majeure, performance of
the obligations will be deferred until the Force Majeure ceases. This section
will not apply to excuse a failure to make any payment when due.

7.7   COUNTERPARTS

This Agreement may be executed in any number of counterparts with the same
effect as if all parties had signed the same document. All of these counterparts
will for all purposes constitute one agreement, binding on the parties,
notwithstanding that all parties are not signatories to the same counterpart. A
fax transcribed copy or photocopy of this Agreement executed by a party in
counterpart or otherwise will constitute a properly executed, delivered and
binding agreement or counterpart of the executing party.

7.8   WAIVER

No failure or delay on the part of any party in exercising any power or right
under this Agreement will operate as a waiver of such power or right. No single
or partial exercise of any right or power under this Agreement will preclude any
further or other exercise of such right or power. No modification or waiver of
any provision of this Agreement and no consent to any departure by any party
from any provision of this Agreement will be effective until the same is in
writing. Any such waiver or consent will be effective only in the specific
instance and for the specific purpose for which it was given. No notice to or
demand on any party in any circumstances will entitle such party to any other or
further notice or demand in similar or other circumstances.

7.9   FURTHER ASSURANCES

Each of the parties will promptly execute and deliver to the other at the cost
of the other such further documents and assurances and take such further actions
as the other may from time to time request in order to more effectively carry
out the intent and purpose of this Agreement and to establish and protect the
rights, interests and remedies intended to be created in favour of the other.

Agreement supersede all previous invitations, proposals, letters,

by reference implicitly or otherwise into this Agreement, unless expressly
referred to in this Agreement.

writing and signed by each party to
this Agreement.

If any provision of this Agreement or any part of any provision (in this section
called the "Offending Provision") is declared or becomes unenforceable, invalid
or illegal for any reason whatsoever including, without limiting the generality
of the foregoing, a decision by any competent courts, legislation, statutes,
bylaws or regulations or any other requirements having the force of law, then
the remainder of this Agreement will remain in full force and effect as if this
Agreement had been executed without the Offending Provision.

7.13  CURRENCY

Unless otherwise specified all sums of money expressed in this Agreement are in
the lawful money of Canada.

                            RESTRICTIONS ON TRANSFER

5.1     RESTRICTION ON TRANSFER.

No Shareholder shall Transfer all or any part of its Interest to any person,
whether a Shareholder or not, except as otherwise expressly provided in this
Agreement.

5.2     RIGHT OF FIRST REFUSAL.

        (a)     A Shareholder (the "Offeror") desiring to transfer any or all of
                its Shares shall give written notice to the Corporation (the
                "Transfer Notice") specifying the number of its Shares that it
                desires to transfer (the "Offered Shares"), the price, in lawful
                money of Canada, for the Offered Shares, and the terms of
                payment upon which the Offeror is prepared to transfer the
                Offered Shares. The Transfer Notice shall constitute the
                Corporation as the agent of the Offeror for the sale of the
                Offered Shares to any other Shareholder or Shareholders at the
                price and upon the terms of payment specified in the Transfer
                Notice. The Transfer Notice shall also state whether the Offeror
                has received an offer to purchase (the "Third Party Offer") the
                Offered Shares, or any of them, from, or proposes to sell the
                Offered Shares, or any of them, to, any particular person or
                persons who are not Shareholders and, if so, the names and
                addresses of those persons and the price and terms in the Third
                Party Offer shall be specified in the Transfer Notice. The
                Transfer Notice shall constitute an offer by the Offeror to the
                other Shareholders to sell the Offered Shares to the other
                Shareholders and shall not be revocable.

        (b)     The Corporation shall forthwith upon receipt of the Transfer
                Notice transmit a copy of it to each Shareholder other than the
                Offeror and shall request that each such Shareholder state in
                writing, within 30 days from the date of the Transfer Notice,
                whether it is willing to purchase any of the Offered Shares and,
                if so, the maximum number it is willing to purchase.

        (c)     Upon the expiration of the 30-day notice period provided for in
                paragraph (b) above, if the Corporation has received from the
                Shareholders entitled to receive the Transfer Notice sufficient
                acceptances to purchase all the Offered Shares the Corporation
                shall thereupon apportion the Offered Shares among the
                Shareholders so accepting pro rata in proportion to the number
                of Shares held by each of them respectively up to the number of
                Offered Shares accepted by each of them respectively. If the
                Corporation did not receive sufficient acceptances to purchase
                all of the Offered Shares, the Corporation may, but only with
                the consent of the Offeror, who shall not be obliged to sell in
                the aggregate less than all the Offered Shares, apportion the
                Offered Shares among the Shareholders accepting pro rata in
                proportion to the number of Shares held by each of them
                respectively up to the number of the Offered Shares accepted by
                each of them respectively.

        (d)     Upon the Corporation's receipt of an acceptance to purchase all
                or any part of the Offered Shares and after an apportionment has
                been made pursuant to


                                      -6-
<PAGE>

                paragraph (c) above, if necessary, a binding contract of
                purchase and sale between the Offeror and the Shareholder who
                transmitted such acceptance shall be deemed to come into
                existence on the terms set out in this Agreement and the
                Transfer Notice, which contract will be completed in the manner
                provided in Section 8.

        (e)     After an apportionment has been made pursuant to paragraph (c)
                above and upon payment of the price for the Offered Shares
                apportioned, the Offeror shall be bound to transfer those shares
                in accordance with that apportionment and if the Offeror fails
                to do so the Corporation shall cause the names of the purchasing
                Shareholders to be entered in the register of members of the
                Corporation as the holders of those shares and shall cancel the
                share certificates previously issued to the Offeror representing
                those shares whether they have been produced to the Corporation
                or not. Payment to the Corporation, as agent for the Offeror, of
                the Purchase Price shall be sufficient payment by the purchasing
                Shareholders and entry of the transfers in the register of
                members of the Corporation shall be conclusive evidence of the
                validity of the transfers. Upon completion of the transfers, and
                delivery of the share certificates duly endorsed in blank for
                transfer, the Corporation shall pay the Purchase Price to the
                Offeror.

        (f)     The Offeror may, for a period of 60 days after the expiration of
                the 30-day period provided for in paragraph (b) above, transfer
                to any person the Offered Shares not purchased by other
                Shareholders pursuant to paragraphs (b), (c), (d) and (e) above,
                provided that:

                (i)     if the other Shareholders did not purchase any of the
                        Offered Shares, the Offeror may not sell less than all
                        the Offered Shares;

                (ii)    the Offeror shall sell the Offered Shares for cash at
                        Closing, free and clear of encumbrances, and on terms
                        that are otherwise identical to those specified in the
                        Transfer Notice;

                (iii)   the Offeror shall not sell any of the Offered Shares to
                        any person, unless at the time of the sale that person
                        complies with Subsection 5.5; and

                (iv)    if the Offeror has not transferred the Offered Shares or
                        any of them within the 60-day period, then the
                        provisions of this Subsection 5.2 shall again become
                        applicable to all of the Offered Shares not disposed of
                        within the 60-day period.

        (g)     The provisions as to transfers of Shares contained in paragraphs
                (a), (b), (c), (d), (e) and (f) of this Subsection 5.2 shall not
                apply:

                (i)     if, before the proposed transfer of Shares is made, the
                        other Shareholders waive their rights to receive the
                        Transfer Notice; or

                (ii)    to any transfer of Shares pursuant to the provisions of
                        Section 6 or 7 of this Agreement.


                                      -7-
<PAGE>

        (h)     The Offeror may include all or any part of its Shareholder's
                Loan (if any) in the Transfer Notice, in which case the
                Shareholder's Loan (or part thereof) shall be included in the
                price of the Offered Shares, and all references to Offered
                Shares in Subsection 5.2 shall include the portion of the
                Shareholder's Loan included therein. If the Offeror does not
                include its Shareholder's Loan in the Transfer Notice, the
                Offeror shall retain its Shareholder's Loan, which shall be
                repaid as the Corporation's finances permit, as determined by
                the directors.

5.3     TRANSFER TO AFFILIATES.

Notwithstanding Subsections 5.1 and 5.2, any Shareholder may sell, transfer or
otherwise dispose of all, but not less than all, of its Interest to an Affiliate
controlled by such Shareholder provided that, prior to any such transfer, the
Shareholder and the Affiliate enter into an agreement with the other parties to
this Agreement, in form and content acceptable to such parties, which provides
that:

        (a)     one hundred percent (100%) of the Shareholder's Interest will be
                transferred to the Affiliate;

        (b)     the Affiliate will remain an Affiliate controlled by the
                Shareholder for so long as the Affiliate holds the Interest;

        (c)     prior to the Affiliate ceasing to be an Affiliate controlled by
                the Shareholder, the Affiliate will transfer its Interest to the
                Shareholder or to another Affiliate controlled by the
                Shareholder, and that such other Affiliate will enter into an
                agreement similar to this Agreement with the other Shareholders
                and the Corporation;

        (d)     the Affiliate will otherwise be bound by and have the benefit of
                the provisions of this Agreement; and

        (e)     the obligations of the original Shareholder hereunder shall not
                in any way be released and shall continue in full force and
                effect.

5.4     NO TRANSFER BY DEFAULTING SHAREHOLDER.

Notwithstanding any other provision of this Agreement, except as required by the
terms of this Agreement, no Shareholder shall be entitled to sell, transfer,
assign or otherwise dispose of its Interest, or any part thereof, without the
prior written consent of the other Shareholders, if it is at that time a
Defaulting Shareholder, unless prior to or concurrently with that sale, transfer
or other disposition it ceases to be a Defaulting Shareholder.

5.5     FURTHER RESTRICTION OF TRANSFER.

No Shareholder shall transfer all or any part of its Interest to any person,
whether a Shareholder or not, who is not a party to or has not agreed to be
bound by this Agreement until such person subscribes to or agrees to be bound by
this Agreement. The Shareholders and the Corporation will not recognize or treat
as a shareholder of the Corporation any person who acquires any


                                      -8-
<PAGE>

interest or control over any Shares or afford any such person the rights
afforded by this Agreement or any of the incidents connected with being a
shareholder of the Corporation until such person subscribes to or agrees to be
bound by this Agreement, and the Shareholders need only deal with as a member of
the Corporation persons who have subscribed to or agreed to be bound by this
Agreement.

                                   SECTION 6
                                    DEFAULT

6.1     EVENTS OF DEFAULT.

An event of default (a "Default") arises if a Shareholder (a "Defaulting
Shareholder"):

        (a)     fails to observe, perform or carry out any of its obligations
                under this Agreement and such failure continues for 30 days
                after any Shareholder not in default (the "Non-defaulting
                Shareholder" individually and the "Non-defaulting Shareholders"
                collectively) gives a written notice of such default to the
                Defaulting Shareholder and the Corporation, which notice shall
                set out particulars of the Default and demand that the Default
                be cured;

        (b)     fails to take reasonable actions to prevent or defend
                assiduously any action, proceeding, seizure, execution, or
                attachment which claims possession, sale, foreclosure, the
                appointment of a receiver or receiver manager of the
                Shareholder's assets, or forfeiture or termination of or
                against, any of the Interest of the Defaulting Shareholder, and
                such failure continues for 30 days after a Non-defaulting
                Shareholder has in writing demanded that such actions be taken
                or the Defaulting Shareholder fails to defend successfully any
                such action, proceeding, seizure, execution or attachment; or

        (c)     commits or is the subject of an Insolvency Event.

6.2     REMEDIES.

If a Default occurs under Subsection 6.1, any one or more of the Non-defaulting
Shareholders may:

        (a)     pursue any remedy available in law or in equity, each
                Shareholder acknowledging that specific performance, injunctive
                relief (mandatory or otherwise) or other equitable relief may be
                the only adequate remedy for a Default;

        (b)     take all actions in their own name or in the name of the
                Defaulting Shareholder, the Shareholders or the Corporation as
                may reasonably be required to cure the Default, and all
                payments, costs and expenses incurred by the Non-defaulting
                Shareholder(s) shall be payable by the Defaulting Shareholder to
                the Non-defaulting Shareholder(s) on demand with interest at the
                Prime Rate plus 2% per annum;


                                      -9-
<PAGE>

        (c)     implement the buy-sell procedure set out in Subsection 6.3 by
                notifying the Corporation of the Default, the name of the
                Defaulting Shareholder and the Non-defaulting Shareholder's
                election to implement such procedure (the "Notice of Default");
                and

        (d)     waive the Default, provided that any waiver of a particular
                Default shall only be effective if it is in writing, signed by
                the Non-defaulting Shareholder, shall not operate as a waiver of
                any subsequent or continuing Default, and shall not be binding
                upon, or limit the remedies available to, any Non-defaulting
                Shareholder who has not signed such waiver.

6.3     BUY-SELL PROCEDURE ON DEFAULT.

In the event the buy-sell procedure in this Subsection 6.3 is implemented
pursuant to paragraph 6.2(c), the Defaulting Shareholder shall be deemed to
offer to sell (the "Offer") to the Corporation and the Non-Defaulting
Shareholder(s) all, but not less than all, of its Interest on the following
terms and conditions:

        (a)     the Purchase Price payable shall be equal to 85% of the fair
                market value of the Defaulting Shareholder's Interest determined
                as of the date of the Notice of Default in accordance with
                Subsection 9.2;

        (b)     upon receipt of the Notice of Default, the President of the
                Corporation shall forthwith:

                (i)     transmit the Notice of Default to each director of the
                        Corporation;

                (ii)    transmit the Notice of Default to each of the
                        Non-defaulting Shareholder(s); and

                (iii)   call a meeting of the Board to consider the Offer;

        (c)     the Corporation shall have the first right to accept the Offer,
                in whole or in part, and to the extent that it is accepted, the
                Non-defaulting Shareholder(s) agree to refuse any pro rata offer
                by the Corporation to purchase the Interest which is required to
                be made by the Corporation under the BUSINESS CORPORATIONS ACT,
                the Articles of the Corporation, the Bylaws of the Corporation
                or this Agreement;

        (d)     if the Offer is not wholly accepted by the Corporation within 30
                days after the date of the Notice of Default:

                (i)     the Secretary of the Corporation shall advise the
                        Non-defaulting Shareholder(s) of the extent to which the
                        Offer is still open, forthwith upon the expiration of
                        the aforesaid 30-day period;

                (ii)    that portion of the Offer not accepted by the
                        Corporation shall be open for acceptance within the next
                        30 days by the Non-defaulting Shareholder(s)


                                      -10-

                        pro rata in accordance with their respective
                        shareholdings in the Corporation;

                (iii)   acceptance by the Non-defaulting Shareholder(s) of the
                        Offer shall be by notice to the Secretary of the
                        Corporation and by such acceptance a Non-defaulting
                        Shareholder may specify any additional portion of the
                        Interest offered for sale that such Non-defaulting
                        Shareholder is prepared to purchase in the event that
                        any of the other Non-defaulting Shareholder(s) fails to
                        accept such Offer, and if any of the other
                        Non-defaulting Shareholder(s) fails to accept such
                        Offer, such Non-defaulting Shareholder (pro rata if more
                        than one) shall be entitled to purchase such additional
                        portion of the Interest as shall be so available;

                (iv)    the Secretary of the Corporation shall advise each of
                        the directors of the Corporation of the extent to which
                        the Offer is still open forthwith upon the expiration of
                        the aforesaid 30-day period;

        (e)     after compliance with paragraph 6.3(d), to the extent the Offer
                has not been accepted, the Corporation shall be deemed to accept
                the Offer with respect to such portion of the Interest as shall
                then be available; and

        (f)     upon the acceptance of the Offer, a binding contract of purchase
                and sale for the Interest of the Defaulting Shareholder shall be
                deemed to be formed between the Defaulting Shareholder and the
                Corporation and/or the Non-defaulting Shareholder(s), as the
                case may be, on the terms and conditions set out in the Offer
                and this Agreement, which contract shall be completed in the
                manner provided in Section 8.

6.4     MONIES HELD.

If and so long as a Shareholder is a Defaulting Shareholder, all monies payable
to that Defaulting Shareholder by the Corporation by way of dividends, repayment
of loans or other distributions shall be held by the Corporation until such time
as the Shareholder is no longer a Defaulting Shareholder.

                                   SECTION 7

                           ACT OWNERSHIP REQUIREMENTS

7.1     COMPULSORY BUY SELL

On the determination of 360, acting reasonably and in good faith, that the
TELECOMMUNICATIONS ACT has been amended to eliminate the requirement for the
Canadian ownership and control of telecommunications common carriers, as defined
in the TELECOMMUNICATIONS ACT, or has otherwise been amended sufficiently to
permit the transactions contemplated by this Section, then 360 shall send a
notice in writing to WFHL of such determination (the "Section 7 Notice") and, on
the occurrence of such event, WFHL shall be deemed to offer to sell to
360-Holdco all of its Interest on the following terms and conditions:


                                      -11-
<PAGE>

        (a)     the purchase price payable shall be the fair market value of
                WFHL's Interest determined as of the date of the Section 7
                Notice in accordance with Subsection 9.2;

        (b)     upon the giving of the Section 7 Notice, a binding contract of
                purchase and sale for the purchase by 360-Holdco and the sale by
                WFHL of the Interests of WFHL shall be deemed to be formed

                Transfer Interest when the Purchaser is ready, willing and able
                to do so, the Purchaser may deposit the Purchase Price for the
                Transfer Interest into a special account at any branch in
                Vancouver, British Columbia of any Canadian chartered bank in
                trust for the Vendor and such deposit shall constitute valid and
                effective payment to the Vendor at the Closing even though the
                Vendor may have voluntarily encumbered or disposed of any of


                                      -13-
<PAGE>

                the Transfer Interest and notwithstanding the fact that a
                certificate or certificates representing any of the Transfer
                Interest may have been delivered to any pledgee, transferee or
                other person.

        (b)     If the Purchaser deposits the Purchase Price for the Transfer
                Interest into a special account pursuant to paragraph 8.6(a),
                then from and after the date of such deposit (even if any
                certificate representing any of the Transfer Interest has not
                been delivered to the Purchaser or the Corporation) the sale and
                purchase of the Transfer Interest shall be deemed to have been
                completed and all right, title, benefit and interest, both at
                law and in equity, in and to the Transfer Interest shall be
                conclusively deemed to have been transferred and assigned to and
                become vested in the Purchaser and all right, title, benefit and
                interest, both at law and in equity, of the Vendor, and of any
                other assignee, transferee or other person having any interest,
                legal or equitable, in or to the Transfer Interest, whether as a
                shareholder or creditor of the Corporation or the Vendor, or
                otherwise, shall cease and determine, but the Vendor shall be
                entitled to receive the Purchase Price for the Transfer
                Interest, without interest, upon completion of all acts and
                deeds as were required of the Vendor to complete the sale of the
                Transfer Interest.

        (c)     For the purposes of this Subsection 8.6, each Shareholder hereby
                irrevocably constitutes and appoints each other Shareholder as
                its true and lawful attorney in fact and agent for, in the name
                of and on behalf of such first Shareholder to execute and
                deliver, and to receive delivery of, all such assignments,
                transfers, deeds, assurances and instruments as may be necessary
                to effectively complete the sale of any Interest pursuant to
                Sections 5, 6 or 7 on the records of the Corporation, and such
                appointment and power of attorney shall not be revoked by the
                bankruptcy, insolvency, winding-up, liquidation, dissolution,
                incapacity or death of such first Shareholder and such first
                Shareholder hereby ratifies and confirms and agrees to ratify
                and confirm all that any other Shareholder, as attorney in fact
                and agent for, in the name of and on behalf of such first
                Shareholder, may lawfully do or cause to be done by virtue of
                this paragraph 8.6(c).

        (d)     If the Purchaser defaults at the Closing in paying the Purchase
                Price for the Transfer Interest, then the Vendor may, by
                delivering written notice to the Purchaser and the Corporation
                that the Vendor is terminating the Contract, terminate the
                Contract and retake possession of the Transfer Interest as the
                absolute owner thereof, in which event the rights of the
                Purchaser in respect of the Transfer Interest shall revert to
                the Vendor and the Vendor shall be entitled, upon delivering to
                the Corporation and each Shareholder its duly executed
                subscription to this Agreement to the return from the
                Corporation of the documents delivered by the Vendor to the
                Corporation in escrow in connection with the Contract.

        (e)     If either the Vendor or the Purchaser fails to complete the
                Contract as required herein, the Contract is specifically
                enforceable and nothing in this Agreement shall be construed to
                mitigate the availability of the remedy of specific performance
                in respect of the Contract in a court of law.

                                   SECTION 9
                         GENERAL PROVISIONS ON TRANSFER

9.1     TRANSFER OF SHARES.

The transfer of the Shares or Interest of any Shareholder pursuant to any of the
terms of this Agreement shall be subject to the general provisions set out in
this Section 9. In the event of any inconsistency between any of the provisions
of Sections 5, 6 or 7 and any of the provisions of this Section 9, the
provisions of this Section 9 shall govern.

9.2     DETERMINATION OF FAIR MARKET VALUE.

        (a)     Where pursuant to the provisions of Sections 6 or 7 of this
                Agreement a determination of the fair market value of an
                Interest is required to be made (in this Subsection 9.2 referred
                to as the "Subject Interest"), a Shareholder may give written
                notice to the other Shareholders requesting that the
                Shareholders forthwith meet and attempt in good faith to agree
                upon the fair market value of the Subject Interest. In the event
                that all of the Shareholders are able to reach agreement on the
                fair market value of the Subject Interest, such agreed value
                shall be deemed to be the fair market value of the Subject
                Interest for the purposes of this Agreement.

        (b)     In the event that the Shareholders are for any reason unable to
                reach agreement on the fair market value of the Subject Interest
                within 14 days of the delivery of the notice referred to in
                paragraph 9.2(a), then the Shareholders shall forthwith meet for
                the purposes of identifying and retaining a valuator (the "First
                Valuator") for the purpose of determining the fair market value
                of the Subject Interest. Unless otherwise unanimously agreed by
                the Shareholders, the First Valuator shall be an accountant
                practising with the Auditors who has at least five years'
                experience in valuating businesses and is accredited as a
                chartered business valuator. In the event that the Shareholders
                do not agree upon a First Valuator within 30 days of the
                delivery of the notice referred to in paragraph 9.2(a), then any
                Shareholder


                                      -15-
<PAGE>

                may refer the determination of the First Valuator to arbitration
                pursuant to Section 11.

        (c)     The First Valuator shall prepare and deliver to each of the
                Shareholders a written report (the "First Valuation Report")
                setting out its Valuation of the Subject Interest as soon as
                possible, and in any event within 45 days after being retained.

        (d)     Any Shareholder may within 30 days of its receipt of the First
                Valuation Report provide written notice to the other
                Shareholders advising that it wishes to have a second Valuation
                of the Subject Interest undertaken. If no such notice is given,
                the First Valuation Report shall be final and binding on the
                parties. If such notice is given the Shareholders shall
                forthwith meet for the purposes of identifying and retaining a
                second valuator (the "Second Valuator") for the purpose of
                preparing a second Valuation of the Subject Interest. The Second
                Valuator shall be an accountant practising with a national
                accounting firm other than the Auditors and who has the
                experience and credentials referred to in paragraph 9.2(b). In
                the event that the Shareholders do not agree upon a Second
                Valuator within 14 days of the delivery of the notice referred
                to in this paragraph, then any Shareholder may refer the
                determination of the Second Valuator to arbitration pursuant to
                Section 11.

        (e)     The Second Valuator shall prepare and deliver to each of the
                Shareholders a written report (the "Second Valuation Report")
                setting out its Valuation of the Subject Interest as soon as
                possible, and in any event within 45 days after being retained.
                Where a Second Valuation Report has been prepared, the fair
                market value of the Subject Interest for the purposes of
                Sections 6 and 7 of this Agreement shall be equal to the average
                of the fair market values of the Subject Interest as set out in
                the First Valuation Report and the Second Valuation Report.

        (f)     The Corporation and each of the Shareholders shall make
                available to the First Valuator and the Second Valuator all
                books, records and other data and information in their
                possession or control as the First Valuator or Second Valuator
                may reasonably require for the purposes of its valuation.

        (g)     In determining the fair market value of the Subject Interest
                under this Subsection 9.2, the First Valuator and the Second
                Valuator may apply such principles of valuation as each
                considers appropriate in the circumstances provided that:

                (i)     there shall be no premium for a control position or
                        discount for a minority position;

                (ii)    the fair market value of any Shareholder Loans shall not
                        be discounted by reason only of the fact that such Loans
                        are not demand loans and may not bear interest; and

                (iii)   the Corporation shall be valued on a going concern
                        basis.


                                      -16-
<PAGE>

        (h)     The Corporation shall pay all fees and expenses charged by the
                First Valuator for preparing the First Valuation Report. The
                Shareholder(s) who request the Second Valuation shall pay all
                fees and expenses charged by the Second Valuator for preparing
                the Second Valuation Report.

        (i)     The First Valuator and the Second Valuator shall be entitled to
                retain such qualified independent appraisers as each may deem
                appropriate to assist with its valuation.

9.3     PAYMENT OF LIENS ON SHARES.

Notwithstanding anything in this Agreement to the contrary, if by reason of any
lien, charge or encumbrance on the Interest of the Vendor, the Vendor is unable
to make delivery of the Vendor's Interest free and clear of all charges, liens
or encumbrances to the Purchaser within the time limited therefor, the Purchaser
shall be at liberty to make payment to the holder of the lien or charge or the
governmental authority imposing the duty, tax, levy or lien, which payment shall
be deemed to be payment to the Vendor and shall be applied in reduction of the
unpaid balance of the Purchase Price and interest accrued thereon.
