                                                  notes, where the old notes were acquired by the broker or dealer as a result of
                                                  market-making activities or other trading activities (except for old notes

Special Procedures for Beneficial
     Owners...............................      If you are a beneficial owner whose old notes are registered in
                                                the name of a broker, dealer, commercial bank, trust company or
                                                other nominee and you wish to tender your old notes in the
                                                exchange offer, you should contact the registered holder promptly
                                                and instruct the registered holder to tender on your behalf.  If
                                                you wish to tender on your own behalf, you must, before
                                                completing and executing the letter of transmittal and delivering
                                                your old notes, either make appropriate arrangements to register
                                                ownership of the old notes in your name or obtain a properly
                                                completed bond power from the registered holder.  The transfer of
                                                registered ownership may take considerable time and may not be
                                                able to be completed before the expiration date.  See "The
                                                Exchange Offer--Procedures for Tendering Old Notes."

Book-Entry Transfer.......................      Any financial institution that is a participant in the Book-Entry

                                                Exchange Offer--Book Entry Transfer."

Acceptance of Old Notes and Delivery
     of New Notes.........................      Upon satisfaction or waiver of all conditions of the exchange
                                                offer, we will accept for exchange any and all old notes which
                                                are properly tendered and not withdrawn before 5:00 p.m., New
                                                York City time, on the expiration date.  The new notes issued
                                                through the exchange offer will be delivered promptly following
                                                acceptance of the old notes by us after the expiration date.  See

                                                Delivery of New Notes."

U.S. Federal Income Tax Consequences......      The exchange of old notes for new notes by tendering holders will
                                                not be a taxable exchange for United States federal income tax
                                                purposes as a result of the exchange.  See "Material United
                                                States and Canadian Federal Income Tax Considerations--United
                                                States."

Regulatory Approvals......................      We do not believe that the receipt of any material federal or
                                                state regulatory approvals will be necessary for the exchange
                                                offer.  See "The Exchange Offer--Regulatory Approvals."

Use of Proceeds...........................      We will not receive any proceeds from the exchange offer.

Resales of the New Notes..................      The new notes are being offered by this prospectus to satisfy
                                                certain obligations contained in the registration rights
                                                agreement.  Based on positions of the Securities and Exchange
                                                Commission and no-action or interpretive letters issued to
                                                others, we believe that the new notes issued through the exchange
                                                offer may be offered for resale, resold and otherwise transferred
                                                by you, without compliance with the registration and prospectus
                                                delivery provisions of the Securities Act, provided that:

                                                o       you are acquiring the new notes in the ordinary course of
                                                        your business;

                                                o       you are not participating, do not intend to participate
                                                        and have no arrangement or understanding with any person
                                                        to participate in the distribution of the new notes; and

                                                o       you are not an affiliate of Worldwide Fiber.

                                                If you acquire new notes in the exchange offer to distribute or participate in a
                                                distribution of new notes, you cannot rely on the position of the staff of the
                                                Securities and Exchange Commission contained in its no-action and interpretive
                                                letters and must comply with the registration and prospectus delivery requirements
                                                of the Securities Act concerning a secondary resale transaction, unless an
                                                exemption from registration is otherwise available. Each broker-dealer that
                                                receives new notes for its own account through the exchange offer must acknowledge
                                                that:

                                                o       old notes tendered by it in the exchange offer were acquired in the
                                                        ordinary course of its business as a result of market-making or other
                                                        trading activities; and

                                                o       it will deliver a prospectus in connection with any
                                                        resale of new notes received in the exchange offer.

                                                This prospectus, as it may be amended or supplemented from time to time, may
                                                be used by a broker-dealer in connection with any resale of the new notes received
                                                in exchange for old notes where the old notes were acquired by a broker-dealer as a
                                                result of market-making or other trading activities, except for old notes acquired
                                                directly from us. We have agreed that, for a period of 180 days following the
                                                consummation of the exchange offer, we will make this prospectus available to any
                                                broker-dealer for use with resale. See "The Exchange Offer--Resales of the New

                                                Summary Description of New Notes

Securities Offered........................      $500,000,000 aggregate principal amount of 12% senior notes that
                                                will mature in 2009.

Issuer....................................      Worldwide Fiber Inc.

Maturity Date.............................      August 1, 2009.

Interest..................................      Interest on the new notes will accrue from the last interest
                                                payment date on which interest was paid on the old notes
                                                surrendered in exchange for new notes or, if no interest has been
                                                paid on the old notes, from the date of original issuance of the
                                                old notes and will be payable in cash in arrears semiannually on
                                                February 1 and August 1 of each year, commencing on February 1,
                                                2000.

Ranking of the New Notes..................      The new notes are senior debts and will rank ahead of all our
                                                future debts that expressly provide that they are subordinated to
                                                the new notes.  They will effectively rank behind all of our
                                                secured debts to the extent of the value of the assets securing
                                                our debts and all existing and future debts and other liabilities
                                                of our subsidiaries.

                                                They will rank equally with all of our existing and future unsubordinated, unsecured
                                                debts that do not expressly provide that they are subordinated to the new notes,
                                                including any old notes not exchanged. On June 30, 1999 the notes were effectively
                                                subordinated to approximately $130.1 million of liabilities of our subsidiaries.
                                                No debt of ours having an equal ranking with the new notes or which is subordinate
                                                to the new notes would have been outstanding at this date.

Optional Redemption.......................      On or after August 1, 2004, we may redeem some or all of the new
                                                notes at any time at the redemption prices, and subject to certain
                                                limitations, described in the section "Description of Notes" under
                                                the heading "Optional Redemption."

                                                Upon a change in the withholding tax laws of Canada, we may redeem
                                                all of the new notes at any time at the face amount of the new
                                                notes.

                                                Before August 1, 2002, we may redeem up to 35% of the new notes with the proceeds of
                                                certain public offerings of our equity at the price listed in the section
                                                "Description of Notes" under the heading "Optional Redemption."

Mandatory Offer to Repurchase.............      If in certain circumstances we sell certain assets, receive
                                                certain excess cash flows, or experience specific kinds of changes
                                                in control, we must offer to repurchase the new notes at the
                                                prices listed in the section "Description of Notes" under the
                                                heading "Repurchase at the Option of Holders."

Basic Covenants of Indenture..............      The indenture governing the new notes contains certain limitations
                                                on our ability, and the ability of some of our subsidiaries, to:

                                                o      borrow money,

                                                o      pay dividends on stock or repurchase stock,

                                                o      make investments,

                                                o      use assets as security in other transactions, and

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

          --   a 2,333 route mile segment from Edmonton to Toronto and
               additional fiber strands along the route from Seattle to Detroit.

     o    In May 1999, we completed construction of the segment of our network
          that extends from Seattle to Portland.

Together this fiber forms the initial backbone of our high-bandwidth fiber optic
communications network and related infrastructure in North America. Our
terrestrial network, when complete, is expected to cover approximately 21,600
route miles and encompass both long haul and intra-city route miles in North
America (comprising in excess of 1,000,000 fiber miles). Our terrestrial network
will consist of:

     o    fiber optic strands installed in protective conduit buried along
          diverse rights-of-way and strands acquired from other developers and
          carriers through swaps, and

     o    related infrastructure such as regeneration shelters.

     Our network is being developed to satisfy increasing demand for fiber optic
capacity for the transmission of data, voice and video generated by
high-bandwidth communications and the requirements of new entrants to the
telecommunications business. We plan to realize the value of the network
through:

     o    the sale, grant of indefeasible rights-of-use, lease or swap of dark
          fiber strands and conduit, and

     o    the provision of bandwidth services, initially along the route from
          Seattle to Toronto via Vancouver, Calgary, Winnipeg, Minneapolis/St.
          Paul, Chicago and Detroit and, in the future, along other parts of our
          network.

     Our present and targeted customer group includes:

     o    communications carriers,

     o    Internet service providers, and

     o    large corporations with enterprise network needs.

     We have also contracted to install a transatlantic fiber optic cable to
expand the connectivity of our network.



                                      -7-
<PAGE>

     We will continue to construct fiber optic networks for third parties on a
contract basis when a project will allow us to retain fiber or conduit assets,
including through indefeasible rights-of-use. We plan to construct these
networks only on routes that complement and reduce the costs of completing our
network or enhance our ability to make a sale, grant of indefeasible
rights-of-use, lease or swap of network capacity or the provision of bandwidth
services.

Market Opportunity

     Our network is designed to provide our customers with secure, independent
transmission facilities and sufficient capacity on a local, regional or national
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:

     o    innovations and advances in transmission technology,

     o    increasing demand for high-bandwidth applications, largely driven by
          the increase in Internet traffic, and

     o    deregulation within the telecommunications industry, which has
          resulted in a proliferation of service providers.

     The North American telecommunications industry has been characterized by
significant demand for high-bandwidth communications services. According to an
industry survey by The Yankee Group:

     o    voice and data telecommunications services revenue in the United
          States is expected to grow at a compounded annual growth rate of
          approximately 8%, from approximately $167 billion in 1997 to
          approximately $241 billion in 2002,

     o    data telecommunications services revenue is expected to grow at a
          compounded annual growth rate of approximately 26%, from approximately
          $15 billion in 1997 to approximately $47 billion in 2002, and

     o    carriers' carrier telecommunications services revenue, which our
          bandwidth services strategy is specifically intended to target, is
          expected to grow at a compounded annual growth rate of approximately
          60%, from approximately $1.2 billion in 1997 to approximately $12.3
          billion in 2002.

Business Strategy

     Our strategy is to be a leading independent provider of technologically
advanced dark fiber and related infrastructure and high-bandwidth fiber optic
transmission capacity. The key elements of our business strategy include:

     o    developing and building a technologically advanced fiber optic network
          connecting many of the major population centers in North America,

     o    maximizing route diversity and connectivity of the network, enabling
          us to target a broad range of customers, by offering participation on
          a local, regional, national or international basis,

     o    creating a low cost position,



                                      -8-
<PAGE>

     o    realizing the value of the network through the sale, grant of
          indefeasible rights of use, lease or swap of network assets and the
          provision of bandwidth services,

     o    providing our customers with low-cost bandwidth services and the
          flexibility to control their service platforms,

     o    allowing for technological upgrades and additional capacity,

     o    installing at least one additional conduit in each segment we develop,
          and

     o    capitalizing on management experience.

The Network

     Our terrestrial network will consist of the following:

     o    a North American long-haul fiber optic network including: (1) two
          primary east-west routes, running from Vancouver to Halifax and
          Sacramento to Boston, and (2) three primary north-south routes,
          running along the West Coast, the Mississippi River valley and the
          East Coast, and

     o    a series of high-bandwidth intra-city networks planned in Toronto,
          Vancouver, Montreal, Ottawa, and Calgary in addition to the intra-city
          network currently under construction in Seattle.

     In addition, we are expanding our network outside of North America through
our transatlantic fiber optic cable project, "Hibernia."

Products and Services

     In connection with the development of our network, we offer customers a
broad range of products and services which enable us to provide customized
solutions. See "Business--Products and Services."

Our products and services include:

     o    dark fiber and conduit for sale, grant of indefeasible rights-of-use,
          lease or swap, and

     o    construction services supporting the development of our network.

     We recently have begun marketing bandwidth services, including optical
transmission, private line, virtual voice, IP transport and ATM. We plan to
begin providing these services by the end of 1999.

Recent Developments

     Private Equity Investment. On September 9, 1999 we completed a private
placement of our convertible preferred shares for $345 million to affiliates of
Tyco International Ltd., Providence Equity Partners Inc., DLJ Merchant Banking
II Inc. and GS Capital Partners III, LP. Together, the privately placed
securities represent a minority equity interest in us. Under the terms of the
sale, each purchaser nominated a representative to our Board of Directors who
has been elected a Director.

     Hibernia Project. In connection with the financing of our $850 million
transatlantic fiber optic cable Hibernia project, we will utilize $300 million
of the proceeds from our equity private placement to fund the equity portion of
the project. We have entered into a project financing commitment letter with
Goldman Sachs



                                      -9-
<PAGE>

Credit Partners LP, DLJ Capital Funding, Inc. and Credit Suisse First Boston.
Under the project financing commitment, it is anticipated that the lenders will
provide up to $600 million in project debt financing to one of our subsidiaries,
non-recourse to Worldwide Fiber Inc.

                                 Financing Plan

     In addition to the fiber assets contributed by Ledcor, we formed a capital
plan in 1998 to develop approximately 12,900 route miles. That plan and the
implementation of bandwidth services contemplate capital expenditures of
approximately $1.26 billion through 2001.

     Consistent with our strategy to create a low-cost position, we have
agreements, subject to terms and conditions we consider customary, with
co-developers and participants. These parties in the aggregate have agreed to
commit approximately $480 million in cash to fund the completion of segments of
our terrestrial network. We expect to complete our network in 2001. We intend to
enter into additional arrangements with co-developers and participants.

     We expect to obtain the balance of the funding necessary to complete our
terrestrial network and to implement our bandwidth services strategy from

     o    the cash remaining from the notes and the 12 1/2% notes issued in
          December 1998, and

     o    up to $150 million in cash available under our planned bank credit
          facility.

     We anticipate that these funding sources will provide us with sufficient
capital to complete our network and to implement our bandwidth services
strategy. However, our costs will depend on a variety of factors, many of which
are beyond our control, including changes in the competitive environment of our
current and planned markets. Our actual costs may vary materially from those
currently budgeted.

     The plan described above does not include equity or debt financing for
Hibernia, which we are funding with the proceeds of our recently completed
equity private placement as well as from our planned non-recourse project
facility.

     We cannot assure you that we will be successful in raising the capital
necessary for the unfunded portion of the remainder of our planned network
development, the implementation of our bandwidth services strategy or for the
Hibernia project on a timely basis or on terms that are acceptable to us, or at
all.

(3)  The initial annual interest expense on the $500,000,000 12% senior notes is
     $62,400,000 and the initial annual interest expense on the $175,000,000
     12 1/2% senior notes is $23,200,000.

(4)  EBITDA consists of net income (loss) before interest expense, net of
     interest income, income tax expense (recovery), depreciation and income
     attributable to minority interest. EBITDA is presented because we believe
     it is a useful indicator of a company's 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 accepted 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.

(5)  For purposes of calculating the ratio of earnings to fixed charges,
     earnings consists of earnings (loss) before equity income, income tax
     expense (recovery), income attributable to minority interest and fixed
     charges. Fixed charges consists of interest expensed and capitalized, plus
     the portion of rental expense which we believe to be representative of
     interest (assumed to be one-third of rental expense). Pro forma loss for
     the year ended December 31, 1998 would have been insufficient to cover
     fixed charges by $69,611,000 and pro forma loss for the six month period
     ended June 30, 1999 would have been insufficient to cover fixed charges by
     $6,141,000.

(6)  Gives pro forma effect to (1) the issuance on July 28, 1999 of the
     $500,000,000 12% senior notes, (2) the issuance on August 31, 1999, of
     150,000 Class B Subordinate Voting Shares for $3,000,000 of cash, (3) the
     issuance on September 9, 1999 of 8,866,808 Series A Non-Voting Preferred
     Shares for $345,000,000 of cash, (4) a stock dividend on September 9, 1999
     of 5,000,000 Series C Redeemable Preferred Shares and a redemption on
     September 9, 1999 of 45,000,000 Series C Redeemable Preferred Shares for
     $45,000,000 of cash and (5) the acquisition on September 27, 1999, from
     affiliates of Ledcor Inc., of certain fiber optic network assets in
     exchange for 4,500,000 Class C Multiple Voting Shares of the Company.

                                  RISK FACTORS

     In addition to the other matters described in this prospectus, you should
carefully consider the following risk factors before making an investment in the
notes.

Limited History of Operations--Given our limited operating history while our
network is being built, you should consider the notes 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 the notes. 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. We believe 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.

Negative Cash Flows--Given our negative cash flows while our network is being
built, you should consider the notes to be a highly speculative investment.

     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 the notes, capital
expenditure requirements or working capital needs.

     We intend to use most of the proceeds from the sale of these notes and a
significant amount of additional capital to develop and construct our network.
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 bandwidth 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 the notes.

     We have substantial debt and debt service requirements.

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

     o    make it more difficult for us to satisfy our obligations under the
          notes,

     o    increase our vulnerability to general adverse economic and industry
          conditions,

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

     o    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,

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



                                      -14-
<PAGE>

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

     o    place us at a competitive disadvantage compared to our competitors
          that have less debt.

     We intend to obtain credit facilities from one or more institutional
lenders in an aggregate amount of up to $150 million. Borrowings under these
credit facilities may be secured by certain of our assets. See "Description of
Other 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 following chart shows certain important credit statistics as of
the date or for the periods specified below:

(1)  Gives pro forma effect to (1) the issuance on July 28, 1999 of the
     $500,000,000 12% senior notes, (2) the issuance on August 31, 1999 of
     150,000 Class B Subordinate Voting Shares for $3,000,000 of cash, (3) a
     stock dividend on September 9, 1999 of 5,000,000 Series C Redeemable
     Preferred Shares and a redemption on September 9, 1999 of 45,000,000 Series
     C Redeemable Preferred Shares for $45,000,000 of cash and (4) the
     acquisition on September 27, 1999, from affiliates of Ledcor Inc., of
     certain fiber optic network assets in exchange for 4,500,000 Class C
     Multiple Voting Shares of the Company.

(2)  Does not give pro forma effect to the issuance on September 9, 1999 of
     8,866,808 Series A Non-Voting Preferred Shares for $345,000,000 of cash.

     The initial annual interest expense on the $500,000,000 12% senior notes is
$62,400,000 and the initial annual interest expense on our $175,000,000 12 1/2%
senior notes is $23,200,000.

     Pro forma loss for the year ended December 31, 1998 would have been
insufficient to cover fixed charges by $69,611,000 and pro forma loss for the
six month period ended June 30, 1999 would have been insufficient to cover fixed
charges by $6,141,000.

Additional Borrowings Required--Despite our current debt level, we and our
subsidiaries plan to 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 build-out of our planned network
and fulfill our long-term business strategies. The terms of the indenture
generally permit us and our restricted subsidiaries to incur additional debt to
finance the cost of designing and building or acquiring our network. The
indenture also allows us to incur additional indebtedness for other purposes,
subject to certain limitations. In addition, the indenture permits us to create
"unrestricted subsidiaries" that will be allowed to incur debt without regard to
the limitations on debt incurrence contained in the indenture. Our ability to
arrange financing and the cost of financing depend upon many factors, including:

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



                                      -15-
<PAGE>

     o    conditions in the telecommunications industry,

     o    regulatory developments,

     o    investor confidence and credit availability from banks or other
          lenders,

     o    the success of our network, and

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

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

     We are funding a portion of our anticipated investment in Hibernia from our
recently completed private sale of our equity securities. We also expect the
indebtedness to finance that project to be incurred by our subsidiary without
recourse to Worldwide Fiber Inc. We estimate that approximately $550,000,000 of
indebtedness will be required for the Hibernia project. Hibernia will be owned
by one or more subsidiaries created for the purpose of owning the project. They
will not hold any assets unrelated to Hibernia. We currently expect that these
subsidiaries will not be restricted subsidiaries under the indenture. If we were
to incur additional debt at the Worldwide Fiber Inc. level in order to
contribute to the financing of Hibernia, 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 the notes and any other 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:

     o    our ability to complete our network on time and in a cost-effective
          manner,

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

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

     o    the passage of legislation or other regulatory developments that may
          adversely affect us, and

     o    any material delays in implementing any strategic projects.

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



                                      -16-
<PAGE>

Holding Company Structure--We will depend on the cash flow of our subsidiaries
to satisfy our obligations under the notes.

     Our operating cash flow and our ability to service our indebtedness,
including the 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.

Restrictions Imposed by Terms of Our Indebtedness--We may be unable to repay the
notes and our other indebtedness if there is an event of default.

     If an event of default occurs under any of our credit facilities or the
indenture, 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. The indenture will limit, and the indenture for our $175,000,000 12
1/2% senior notes due 2005 does limit, among other things, our ability to incur
additional indebtedness, pay dividends and make certain other restricted
payments, incur liens, enter into certain transactions with affiliates and
consummate asset sales and does impose restrictions on our ability to merge or
consolidate with or into, 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 indenture. 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 future accounts receivable and inventory of Worldwide Fiber 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.

Failure to Exchange or Comply with the Exchange Offer--This will result in
continuing transfer restrictions or result in the inability to exchange.

     There has previously been only a limited secondary market, and no public
market, for the old notes. To the extent that old notes are tendered and
accepted in the exchange offer, the trading market, if any, for the old notes
not so tendered could be adversely affected. We cannot assure the future
development of a market for the old notes or the ability of holders of the old
notes to sell their old notes or the price at which the old notes may be sold.
If you do not exchange your old notes for new notes under the exchange offer,
you will continue to be restricted from transferring your old notes.

     In general, the old notes may not be offered or sold, unless registered
under the Securities Act, except under an exemption from, or in a transaction
not subject to, the Securities Act and applicable state securities laws. We do
not currently anticipate that we will register the old notes under the
Securities Act. Based on interpretations by the staff of the Securities and
Exchange Commission contained in no-action letters issued to third parties, we
believe that the new notes issued to you under the exchange offer in exchange
for old notes may be offered for resale, resold or otherwise transferred by any
holder of them, except for any holder which is an affiliate of Worldwide Fiber
within the meaning of Rule 405 under the Securities Act, without compliance with
the



                                      -17-
<PAGE>

registration and prospectus delivery provisions of the Securities Act, if the
new notes are acquired in the ordinary course of the holder's business and the
holder is not participating, does not intend to participate and has no
arrangement or understanding with any person to participate in the distribution
of the new notes. This prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer for any resale of new notes
received in exchange for old notes where the old notes were acquired by this
broker-dealer as a result of market-making activities or other trading
activities, except for old notes acquired from us. We have agreed that, for a
period of 180 days following the completion of the exchange offer, we will make
this prospectus available to any broker-dealer for use in any resale. However,
your ability to resell the new notes is subject to applicable state securities
laws. See "The Exchange Offer" and "Plan of Distribution."

     To participate in the exchange offer and avoid the restrictions on transfer
of the old notes, you must deliver a properly completed letter of transmittal,
including all other documents required by the letter of transmittal, to the
exchange agent at one of the addresses listed below under "The Exchange
Offer--Exchange Agent" on or before the expiration date. In addition, either

     o    certificates for the old notes must be received by the exchange agent
          along with the letter of transmittal,

     o    a timely confirmation of a book-entry transfer of the old notes, if
          this procedure is available, into the exchange agent's account at the
          Book-Entry Transfer Facility under the procedure for book-entry
          transfer described in this prospectus must be received by the exchange
          agent before the expiration date, or

     o    the holder must comply with the guaranteed delivery procedures
          described in this prospectus and in the letter of transmittal. You may
          elect to choose method of delivery of the old notes and the letter of
          transmittal and all other required documents to the exchange agent but
          it is at your own risk. See "The Exchange Offer."

Effective Subordination--Although your notes are referred to as "senior notes,"
they will be effectively subordinated to our secured debt and the debt of our
subsidiaries.

     The notes are unsecured and therefore will be effectively subordinated to
any secured debt we may incur to the extent of the value of the assets securing
it. In the event of a bankruptcy or similar proceeding involving us, our assets
which serve as collateral will be available to satisfy the obligations under any
secured debt before any payments are made on the notes. In addition, our
subsidiaries will not guarantee the notes. In the event of a bankruptcy,
liquidation or reorganization of any of our subsidiaries, creditors of our
subsidiaries will generally be entitled to payment of their claims from the
assets of those subsidiaries before any assets are made available for
distribution to us, except to the extent we may also have a claim as a creditor.

Risks Associated with Construction and Expansion of Our Network--Our inability
to implement our business strategy and manage our growth could cause significant
delays in the completion of our network.

     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 management personnel. Adverse economic or competitive
conditions or the failure to obtain the necessary authorizations or to hire and
retain qualified management 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 conditions acceptable to us:

     o    obtain access to capital markets,



                                      -18-
<PAGE>

     o    design and engineer fiber networks,

     o    install fiber optic facilities, transmission equipment and related
          infrastructure,

     o    acquire rights-of-way,

     o    attract and retain high-quality operating personnel and management,
          and

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

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

     o    management's ability to effectively control and manage these projects,

     o    shortages of materials or skilled labor,

     o    unforeseen engineering, environmental or geological problems, and

     o    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 ability to implement our business plan depends, to a significant
degree, upon our ability to secure a market for our fiber capacity and obtain
and maintain contractual and other relationships with communications carriers
and corporate customers. 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. Certain 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 may expand the range of services that we offer. These
services may include leasing bandwidth or entering into joint ventures where we
supply customers with dark fiber and our partners supply the appropriate optical
transmission equipment by facilitating the involvement of third party suppliers,
vendors and contractors. We also intend to offer bandwidth services to carriers
and other service providers. 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.

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 local 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. Certain 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, one of our subsidiaries is seeking an order from the
Canadian telecommunications regulatory authority which will permit us to
continue to have access to street crossings and other municipal properties in
the City of Vancouver. See "--Extensive Regulation--Canada--CRTC Applications."
In addition, landholders who granted rights-of-



                                      -19-
<PAGE>

way to certain 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 Illinois Central Railroad Company and
Canadian National Railway 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--General."

Limited Nature of our Activities--We do not offer a broad range of products or
services and this could increase our vulnerability to changing trends in our
industry or increased competition.

     The limited nature of our current activities could limit potential revenues
and result in lower revenues than competitors who now provide a wider array of
services. Presently, we derive substantially all of our revenues from the sale,
grant of indefeasible rights-of-use or lease of dark fiber and conduit and
construction services. While we have recently commenced marketing bandwidth
services to carriers and other service providers, we cannot assure you that we
will be successful in entering this business. See "Business--Customers" and
"--Competition."

Pricing Pressures--We anticipate that prices for fiber assets and bandwidth
services will start to 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:

     o    price competition as various network providers complete construction
          of networks that might compete with our network,

     o    installation by us and our competitors of excess fiber capacity,

     o    recent technological advances that permit substantial increases in the
          transmission capacity of both new and existing fiber optic networks,
          and

     o    strategic alliances or similar transactions, such as long distance
          capacity purchasing alliances among certain Regional Bell Operating
          Companies, that increase the parties' purchasing power.

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:

     o    physical damage,

     o    power loss,

     o    capacity limitations,

     o    software defects,

     o    excessive sustained or peak user demand,

     o    breaches of security, and



                                      -20-
<PAGE>

     o    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.

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

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 or assets may not be returned.

     We are continually evaluating potential joint ventures and strategic
opportunities. An affiliate of Michels Pipeline Construction Inc., a U.S.
pipeline construction company, has a 25% interest in Worldwide Fiber (USA), Inc.
Illinois Central Railroad Company and Canadian National Railway Company have
minority interests in our subsidiaries which will construct our network along
the rights-of-way of these railroads and we are seeking equity participants in
our transatlantic cable project. 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:

     o    the difficulty of identifying appropriate joint venture partners or
          opportunities,

     o    the time our senior management must spend negotiating agreements and
          monitoring joint venture activities,

     o    potential regulatory issues applicable to telecommunications
          businesses,

     o    the investment of our capital or fiber assets and the loss of control
          over the return of this capital or assets,

     o    the inability of management to capitalize on the growth opportunities
          presented by joint ventures, and

     o    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 bandwidth services outside of North America. In particular, we have
recently entered into an agreement for a transatlantic cable project called
Hibernia. We are still evaluating all of the risks associated with this new
project. We expect that the risks associated with Hibernia include:

     o    activities from our competitors which could limit the market share
          obtained by Hibernia,

     o    pricing pressures which could reduce profitability,

     o    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

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

     Other risks associated with Hibernia and our international plans include:

     o    regulatory limitations restricting or prohibiting us from providing
          our services,

     o    additional regulatory requirements, tariffs, customs, duties and other
          trade barriers,

     o    difficulties in staffing and managing foreign operations,

     o    problems in collecting accounts receivable,

     o    political risks,

     o    fluctuations in the currency exchange and restrictions on the
          repatriation of earnings,

     o    delays from customs brokers or government agencies, and

     o    potentially adverse tax consequences resulting from operating in
          multiple countries with different laws and regulations.

     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.

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 a number of components and parts used in the network. We are
also dependent on Nortel Networks, Newbridge Networks and Fore Systems for the
transmission equipment we will need to offer bandwidth services. We believe that
there are alternative suppliers or alternative components for all of the
components and transmission equipment contained in the network or required to
offer bandwidth services. However, any delay or extended interruption



                                      -22-
<PAGE>

in the supply of any of the key components, changes in the pricing arrangements
with our suppliers and manufacturers or delay in transitioning 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.
In addition, we have contracted with Tyco Submarine Systems Ltd. as our primary
contractor for our transatlantic cable project. See "Prospectus Summary--Recent
Developments--International Expansion." 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.

Competition--Our business is very competitive and increased competition could
adversely affect us.

     The telecommunications industry is extremely competitive, particularly
concerning price and service. We face competition from existing and planned
telecommunications systems on each of our planned routes. Our competitors
include:

     o    interexchange carriers, including AT&T Corp., MCI WorldCom, Inc. and
          Sprint Corporation,

     o    wholesale providers, including Qwest Communications International
          Inc., Williams Communications Group, Inc., IXC Communications, Inc.,
          DTI Holdings, Inc., Global Crossing Ltd. and Level 3 Communications,
          Inc.,

     o    incumbent local exchange carriers, which currently dominate their
          local telecommunications markets, including Ameritech Corporation and
          GTE Corporation,

     o    competitive local exchange carriers, including GST Telecommunications,
          Inc. and Metromedia Fiber Network, Inc., and

     o    potential competitors capable of offering services similar to those
          offered by us, including communications service providers, cable
          television companies, electric utilities, microwave carriers,
          satellite carriers, wireless telephone operators and large end-users
          with private networks.

     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 us and could directly compete with us in the market for fiber
assets or bandwidth 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."



                                      -23-

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 certain 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 bandwidth 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 certain things. Its interests may conflict with your interests.

     As of the date of this prospectus, Ledcor holds shares in us which entitle
Ledcor to over 99% of the votes attached to our shares and Ledcor has the
ability to control our affairs and business. It is possible that Ledcor's
interests could conflict with your interests. In addition, Ledcor may have an
interest in causing us to pursue transactions that, in its judgment, enhance the
value of its equity investment in us, 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.

     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
Worldwide Fiber. 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
Worldwide Fiber. As a result, if a change of control of Worldwide Fiber 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
"Transactions with Our Parent--Description of Reorganization and Related
Agreements."

     We also rely on Ledcor to provide us with administrative and other
services. Ledcor has the right to cease providing these services at any time.
See "Transactions with Our Parent--Description of Reorganization and Related
Agreements."

Year 2000 Compliance--We could be adversely affected if Year 2000 problems are
significant.

     The Year 2000 issue is the result of many computer programs being written
using two digits rather than four to define the applicable year. Computer
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than 2000. This could result in a system failure or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities. Most of our systems that would require
Year 2000 modifications are currently maintained by Ledcor under the Management
Services Agreement and by Worldwide Fiber Networks, Inc. While we believe that
they are taking adequate steps to prepare our computer systems for the Year
2000, if necessary modifications and conversions are not made, or are not
completed in time, the Year 2000 issue could have a material adverse impact on
our operations. Furthermore, the systems of other companies on which our systems
rely, including those of Ledcor, may not be prepared for the Year 2000, or these
companies may implement Year 2000 preparations with systems that are
incompatible with our systems. In that event, our operations and financial
condition may be materially and adversely affected. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Year 2000 Date
Conversion."

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 Communication
Commission, but would be subject to universal service payments based on the
gross revenues from end users. See "Regulation--United
States--Federal--Telecommunications Service--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.

     The precise parameters of the definition of a telecommunications service
are currently unclear. A decision by the Federal Communications Commission that
telecommunications and common carrier services are



                                      -25-
<PAGE>

essentially the same is on appeal to a federal appeals court. A reversal or
remand of that decision could impact the Company's position that it should not
be regulated as either a telecommunications or a common carrier. In addition,
certain 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's 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. There can be no assurance 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 under the notes.

     The continuation of tariff filing requirements for interstate domestic
services provided by nondominant carriers is in dispute. The Federal
Communications Commission has ordered that all nondominant 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 nondominant 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 FCC 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 under the notes.

     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.

     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--CLEC 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



                                      -26-
<PAGE>

parity to competing providers, and nondiscriminatory 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 CLEC interstate access charges are generally
regulated as non-dominant carrier offerings and subject to minimal burdens, the
FCC recently adopted a Notice of Proposed Rulemaking that asks whether it should
regulate the terminating access charges of such providers.

     The Federal Communications Commission recently 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

     The Company is 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
some 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
carrier interstate access services.

     The Telecommunications Act of 1996 currently requires Regional Bell
Operating Companies to obtain Federal Communications Commission authorization
prior to providing inter-LATA telecommunications. None has received such
authority to date. It is anticipated that some Regional Bell Operating Companies
may receive authorization in some states to provide inter-LATA
telecommunications as early as the end of 1999. If such authority is granted,
this 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 Commis-



                                      -27-
<PAGE>

sion 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 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.

     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
certain 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)

     We intend to retain fiber assets in our network which will be available for
sale, grant of indefeasible rights-of-use, lease or swap. To the extent that we
engage in these activities, particularly when we provide dark or lit fiber on a
leased basis, we will be subject to the provisions of the Telecommunications Act
(Canada) and to regulation by Canada's telecommunications regulatory authority,
the Canadian Radio-television and Telecommunications Commission. Although we do
not believe that these activities will be subject to extensive regulation, there
can be no assurance that the underlying policies of the Canadian
Radio-television and Telecommunications Commission, which generally foster
competition in Canada's local and long distance telecommunications services
markets, will not change in the future.

     In a 1995 decision, the Canadian Radio-television and Telecommunications
Commission concluded that telecommunications services provided by non-dominant
carriers should not be subject to extensive regulation. We believe that all of
the telecommunications services that we will provide qualify under this decision
as non-dominant carrier services. As such, we do not believe that our operations
in Canada will be subject to extensive regulation by the Canadian
Radio-television and Telecommunications Commission. However, the Canadian
Radio-television and Telecommunications Commission's view as to the need for and
extent of regulation over non-dominant carriers may change. As a result, there
can be no assurance that the regulatory environment in Canada will continue to
be favorable to non-dominant carriers. Any change in the Canadian
Radio-television and Telecommunications Commission's policies or regulations
relating to non-dominant carriers could have a material adverse effect on our
business, financial condition and results of operations if, as a result of those


                                      -28-
<PAGE>

changes, our services, rates or operations become subject to greater regulatory
oversight and intervention by the Canadian Radio-television and
Telecommunications Commission.

     Restrictions on Foreign Ownership

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

     To the extent that we make available the retained fiber in our network in
Canada on an indefeasible rights-of-use or lease basis, we will be subject to
the Canadian ownership provisions of the Telecommunications Act. Although we
believe that we are in compliance with the relevant legislation, there can be no
assurance that a future Canadian Radio-television and Telecommunications
Commission determination or events beyond our control will not result in us
ceasing to comply with the ownership provisions of the Telecommunications Act.
Should this occur, our ability to operate as a Canadian carrier under the
Telecommunications Act could be jeopardized and our business could be materially
adversely affected.

     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
rights-of-use interest in an international submarine cable would not necessarily
fall within the definition of a telecommunications common carrier. As a result,
acquirors 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 rights-of-use interests held in international
submarine cables, as well as the fact that indefeasible rights-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 constructed by us, would
be exempt from the Canadian ownership provisions contained in the
Telecommunications Act.

     In addition to determining the status of indefeasible rights-of-use under
the Telecommunications Act, the Canadian Radio-television and Telecommunications
Commission 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, telecommunications
service providers 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 segments of the network in Canada may choose to
purchase, lease or obtain indefeasible rights-of-use 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 network, which could have a material adverse effect on our
business, financial condition and results of operations.

     Contribution

     As a result of a September 17, 1998 application by four interexchange
carriers, 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 carrier's 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. If the Canadian Radio-television and Telecommunications Commission
decides to adopt the approach advocated in the application filed by the four
interexchange carriers, the current contribution regime would be converted to a
revenue-based regime under which contribution would be 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 our operations in Canada would be subject to the
requirement to pay contribution under the current contribution regime, except
with the possible exception of fiber which we may lease on a lit basis. 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 contribution in the future,
particularly if the Canadian Radio-television and Telecommunications Commission
decides to adopt a revenue-based regime.

     CRTC Applications

     On March 19, 1999, we filed an application with the Canadian
Radio-television and Telecommunications Commission seeking orders under the
Telecommunications Act which would permit us 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 our network facilities within
that city. In an answer to our application, the City of Vancouver took the
position that we were 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 certain
of the carriers that have obtained indefeasible rights-of-use from us to
continue to construct, operate and maintain those facilities on a zero rate
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. The Canadian
Radio-television and Telecommunications Commission has yet to render a decision
with respect to these applications. Failure to obtain the orders we have
requested could have a material adverse effect on our business, financial
condition and results of operations.

Bankruptcy and Related Laws--Your rights concerning the notes could be adversely
affected in a United States or Canadian bankruptcy proceeding.

     Canadian courts have exercised their powers under the Bankruptcy and
Insolvency Act, and particularly under the Companies' Creditors Arrangement Act,
broadly to protect a restructuring entity from actions taken by creditors and
other parties. Accordingly, it is impossible to predict if payments under the
notes would be made



                                      -30-
<PAGE>

during these proceedings, whether or when the trustee could exercise rights
under the indenture or whether and to what extent you would be compensated for
any delays in payments, if any, of principal and interest.

     There could also be a bankruptcy filing by or against us in the United
States. U.S. bankruptcy courts typically have jurisdiction over a debtor's
property, wherever it is located, including property located in other countries.
However, courts outside of the United States might not recognize the U.S.
bankruptcy court's jurisdiction. Accordingly, difficulties may arise in
administering a United States bankruptcy case involving a Canadian debtor with
property located outside of the United States. Orders or judgments of a
bankruptcy court in the United States may not be enforceable against third
parties outside the United States.

     We are organized under the laws of Canada. At present, a significant
portion of our assets is located in Canada. The notes and the indenture will be
governed by New York law. The rights of the trustee under the indenture to
enforce remedies could be significantly impaired by the restructuring provisions
of applicable Canadian or United States federal bankruptcy, insolvency and other
restructuring legislation if the benefit of this legislation is sought
concerning us. For example, in Canada, both the Bankruptcy and Insolvency Act
(Canada) and the Companies' Creditors Arrangement Act (Canada) contain
provisions enabling "an insolvent person" to obtain a stay of proceeding against
its creditors and others and to prepare and file a proposal for consideration by
all or some of its creditors to be voted on by the various classes of its
creditors. This restructuring proposal, if accepted by the requisite majorities
of creditors and if approved by the court, would be binding on all creditors who
fall within one of the classes of creditors contemplated by the restructuring
proposal. Moreover, this "proposal" legislation permits, in certain
circumstances, the insolvent debtor to retain possession and administration of
its property, even though it may be in default under the applicable debt
instruments.

     If there were a filing by or against us in the United States, the U.S.
Bankruptcy Code provides for an automatic stay of virtually all proceedings
against a debtor which stay continues until a bankruptcy plan of reorganization
is confirmed or the stay is lifted under a noticed motion. Similar to the
Canadian laws, the U.S. Bankruptcy Code provides that a plan of reorganization,
if accepted by the requisite majorities of creditors and if approved by the
court, would be binding on all creditors who fall within one of the classes of
creditors contemplated by the plan of reorganization. Moreover, the U.S.
Bankruptcy Code also generally permits the insolvent debtor to retain possession
and administration of its property, even though it may be in default under the
applicable debt instruments. Accordingly, it is also impossible to predict if
payments under the notes would be made during a U.S. bankruptcy proceeding,
whether or when the trustee could exercise its rights under the indenture or
whether and to what extent you would be compensated for any delays in payments,
if any, of principal and interest.

Financing Change of Control Offer--We may not have the ability to raise the
funds necessary to finance the change of control offer required by the
indenture.

     Upon the occurrence of certain specific kinds of change of control events,
we will be required to offer to repurchase all outstanding notes. However, it is
possible that we will not have sufficient funds at the time of the change of
control to make the required repurchase of notes or that restrictions in our
credit facilities or other indebtedness will not allow these repurchases. In
addition, certain important corporate events, such as leveraged
recapitalizations that would increase the level of our indebtedness, would not
constitute a change of control under the indenture. See "Description of
Notes--Repurchase at the Option of Holders."

There may be no public market for the new notes.

     There has previously been only a limited secondary market, and no public
market, for the old notes. The new notes are a new issue of securities, have no
established trading market, and may not be widely distributed. Worldwide Fiber
does not intend to list the new notes on any national securities exchange or the
Nasdaq Stock Market or to apply for the trading of the notes on any automated
quotation system. No assurance can be



                                      -31-
<PAGE>

given that an active public or other market will develop for the new notes or as
to the liquidity of or the trading market for the new notes. If a trading market
does not develop or is not maintained, holders of the new notes may experience
difficulty in reselling the new notes or may be unable to sell them at all. If a
market for the new notes develops, this market may be discontinued at any time.
If a public trading market develops for the new notes, future trading prices of
the new notes will depend on many factors, including, among other things,
prevailing interest rates, our results of operations and the market for similar
securities, and the price at which the holders of new notes will be able to sell
the new notes is not assured and the new notes could trade at a premium or
discount to their purchase price or face value. Depending on prevailing interest
rates, the market for similar securities and other factors, including our
financial condition, the new notes may trade at a discount from their principal
amount.

You may not be able to rely on forward-looking statements.

     The information contained in this prospectus includes some forward-looking
statements that involve a number of risks and uncertainties. A number of factors
could cause our actual results, performance, achievements or industry results to
be very different from the results, performance or achievements expressed or
implied by our forward-looking statements. These factors include, but are not
limited to:

     o    general economic and business conditions, both nationally and in the
          markets in which we operate or will operate,

     o    our ability to access markets, design effective fiber optic routes,
          install cable and facilities, and obtain rights-of-way, building
          access rights and any required governmental authorizations, franchises
          and permits, all in a timely manner, at reasonable costs and on
          satisfactory terms and conditions,

     o    demographic change,

     o    competition,

     o    existing government regulations and changes in, or the failure to
          comply with, government regulations,

     o    the loss of any significant number of customers,

     o    changes in business strategy or development plans,

     o    technological developments,

     o    the ability to attract and retain qualified personnel, and

     o    other factors we refer to throughout this prospectus.

     Certain of these factors are discussed in more detail elsewhere in this
prospectus including, without limitation, under the captions "Risk Factors" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

     In addition, forward-looking statements depend upon assumptions, estimates
and dates that may not be correct or precise and involve known and unknown
risks, uncertainties and other factors. Accordingly, a forward-looking statement
in this prospectus is not a prediction of future events or circumstances and
those future events or circumstances may not occur. Given these uncertainties,
you are warned not to rely on the forward-

looking statements. Neither we nor any other person assumes responsibility for
the accuracy and completeness of these statements. A forward-looking statement
is usually identified by our use of certain terminology, including "believes,"
"expects," "may," "will," "should," "seeks," "pro forma," "anticipates" or
"intends" or by discussions of strategy or intentions. We are not undertaking
any obligation to update these factors or to publicly announce the results of
any changes to our forward-looking statements due to future events or
developments.

                             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, are derived from the audited financial statements of the
predecessor division, which have been audited by Deloitte & Touche LLP,
independent auditors. Worldwide Fiber was incorporated on February 5, 1998 and
acquired certain assets of the predecessor division on May 31, 1998. Before May
31, 1998, Worldwide Fiber was a shell company. The selected historical financial
data presented for the period February 5, 1998 through December 31, 1998 of
Worldwide Fiber are derived from our audited consolidated financial statements,
which have been audited by PricewaterhouseCoopers LLP, independent auditors. The
unaudited pro forma financial data for the year ended December 31, 1998 are
derived from the audited consolidated financial statements of Worldwide Fiber,
the financial statements of the predecessor division, and the consolidated
financial statements of Worldwide Fiber (USA), Inc. ("WFI-USA") included
elsewhere in this prospectus. The selected historical financial data presented
for the periods ended June 30, 1999 and 1998 are derived from Worldwide Fiber's
unaudited consolidated financial statements and include, in the opinion of
Worldwide Fiber's management, all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the data for those periods.
The unaudited pro forma financial data for the six months ended June 30, 1999
are derived from the unaudited interim consolidated financial statements for the
six month period ended June 30, 1999 of Worldwide Fiber included elsewhere in
this Prospectus. Our consolidated financial statements and the divisional
financial statements of the predecessor division are not comparable to our
results of operations after the Reorganization. You should read the following
information along with "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business" and the financial statements
and the related notes included elsewhere in this prospectus.

     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 at
the end of the period, calculated without including physically overlapping
segments of cable. Fiber miles represent the number of strands of fiber in a
length of fiber optic cable owned at the end of the period, multiplied by the
length of the cable in miles.

     it is a useful indicator of a company's 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

     the portion of rental expense which we believe to be representative of
     interest (assumed to be one-third of rental expense). Pro forma loss for
     the year ended December 31, 1998 would have been insufficient to cover
     fixed charges by $69,611,000 and pro forma loss for the six month period

                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 Limited, including the related notes, included
elsewhere in this prospectus.

General

     We are a provider of technologically advanced fiber optic communications
infrastructure in North America using our state-of-the-art fiber optic network.
We recently have begun marketing bandwidth services and intend to provide these
services by the end of the year. We are developing our network to satisfy
increasing demand for fiber optic capacity for the transmission of data, voice
and video generated by high-bandwidth communications and the requirements of new
entrants to the telecommunications business. We currently derive our revenues
from the sale, grant of indefeasible rights-of-use ("IRU") and lease of dark
fiber optic strands and conduit and related infrastructure. We have commenced
the process of adding the necessary optical transmission equipment to enable us
to provide bandwidth services to carriers and other service providers. Our
targeted customers include communications carriers, Internet service providers
("ISPs") and large corporations with enterprise network needs.

     The development and build-out of our network will require significant
capital expenditures through 2001, when the network is scheduled to be complete.
Depending upon market demand, we may expand the network and will require
additional capital if we decide to do so. See "--Liquidity and Capital
Resources."

Reorganization

     We were incorporated on February 5, 1998. However, we did not commence
operations until May 31, 1998. As of May 31, 1998 we entered into a series of
agreements whereby Ledcor transferred the construction equipment, certain fiber
optic strands and certain other assets of Ledcor's telecommunications division
(the "Reorganization"). Because this series of transactions was 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 value of the fiber assets we received is 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 certain
builds along the fiber optic transmission system across Canada and the Northern
United States (the "FOTS"). In return, Ledcor paid us an amount equal to our
costs incurred plus 15%. Our obligations under these agreements were
substantially performed by the end of January 1999. We also entered into a
Management Services Agreement and two Employee Services Agreements with Ledcor.
See "Transactions with Our Parent--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's 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's telecommunications division prior to May 31, 1998 reflect
the operations of our predecessor as a contractor and network developer for the
FOTS. 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.



                                      -38-
<PAGE>

Sources of Revenue

     To date, we have primarily generated revenues from the construction of our
fiber optic network. We will continue to construct fiber optic networks for
third parties on a contract basis when these networks will either allow us to
retain fiber or conduit assets on routes that complement and reduce the costs of
completing our network, or to enhance our ability to make a sale, grant of
indefeasible rights-of-use, lease or swap of network capacity or the provision
of bandwidth services. We anticipate that, as we proceed with the development of
our network, the percentage of revenues which we receive from construction
services will decline from the level reflected in our results of operations to
date.

     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.

     As a developer, we use a condominium strategy to develop the network. Our
condominium strategy allows multiple participants to purchase, obtain
indefeasible rights-of-use or lease fiber or conduit along a segment of our
network at a fixed price. We generally commence construction of a segment when
we have pre-sold sufficient strands and conduit to cover approximately 50% of
our anticipated construction costs of that segment. Under participation
agreements, we typically receive an initial deposit with the final payment
coming after acceptance by the customer. To expedite route development or
decrease development risk, we may seek a co-developer. Co-developers typically
make a deposit and progress payments that represent their share of the project
construction costs. They may also enter into co-marketing arrangements with us
to sell the assets along the build.

     We recognize revenue for participation agreements on a percentage of
completion basis. Following completion of a build, our retained fiber or conduit
may be sold, granted through an indefeasible right-of-use or leased to a third
party. Revenues and costs for a sale or grant of indefeasible rights-of-use of
these fiber or conduit assets are recognized at the time of the transaction.
Lease revenues are recognized as earned over the life of the lease.

     In the future we anticipate a significant amount of our revenues will be
derived from providing bandwidth services, including optical transmission,
private line, virtual voice, IP transport and ATM.

Joint Ventures

     Our consolidated balance sheet at June 30, 1999 and December 31, 1998
includes the assets and liabilities of WFI-USA, and a minority interest in it,
reflecting our 75% interest in WFI-USA. A fifty percent interest in WFI-USA was
transferred to us by Ledcor on August 31, 1998, and the additional 25% was
acquired on December 31, 1998 from the treasury of WFI-USA. The consolidated
income statements for the periods ended June 30, 1998 and December 1998 account
for Worldwide Fiber's initial 50% interest in WFI-USA using the equity method.
Worldwide Fiber Networks, Inc. ("WFNI") will be the primary subsidiary through
which we will develop the U.S. segments of the network. Subsequent to December
31, 1998 we also began consolidating WFI-USA's income statement and became
responsible for supplying all of the capital necessary to fund those segments of
the network developed through WFNI. See "Business--Description of WFI-USA
Agreements."

     We have entered, and may in the future enter, into joint ventures to
develop particular segments of the network, to secure rights-of-way ("ROW") or
to enable us to provide bandwidth or other services on a more timely or capital
efficient manner or for other reasons. For example, we entered into agreements
with Illinois Central Railroad Company ("IC") and Canadian National Railway
Company ("CN") which allow us to develop



                                      -39-
<PAGE>

our network on both railroads' ROW in Canada and the United States. See
"Business--Description of IC and CN Agreements."

Results of Operations

Worldwide Fiber Inc.
  Six Months Ended June 30, 1999

     Revenue for the six month period ended June 30, 1999 was $123,884,000. This
revenue was primarily derived from sales of conduit and fiber optic strands
along the Seattle-Portland, Portland-Sacramento and northeast segments of our
network. The Seattle-Portland segment was completed in May 1999.

     Costs were $85,614,000 for the six months ended June 30, 1999 and reflect
the costs incurred in development of our network which include costs related to
subcontractors, rights-of-way and equipment purchases. Costs as a percentage of
revenue for the period were 69%. The resulting gross margin for the period of
$38,270,000 and gross margin percentage of 31% have increased from prior periods
due to the higher margins achieved in network development compared to
construction services rendered to Ledcor and third parties during prior periods.

     General and administrative expenses were $5,837,000 or 5% of revenue for
the six months ended June 30, 1999. We are continuing the process of
implementing our own management information and accounting systems. General and
administrative expenses are expected to continue to increase as we develop our
systems, hire additional personnel and implement our bandwidth services
strategy.

     Interest expense was $7,970,000 for the six months ended June 30, 1999 and
was principally due to the issue of the 1998 Notes. Interest income totalled
$2,299,000 for this period and arose from the investment of the proceeds of the
1998 Notes in short-term, investment grade securities. Interest capitalized for
the period totaled $2,481,000.

     Income taxes provided for the six month period of $10,921,000 consist
primarily of current taxes arising from our U.S. and Canadian operations.

     Minority interest for the six month period of $2,995,000, represents 25% of
WFI-USA's net income.

Period from February 5, 1998 to June 30, 1998
  (Operations commenced June 1, 1998)

     Revenue for the period ended June 30, 1998 was $12,280,000 and was
principally derived from the Construction Services Agreements with Ledcor.

     Costs were $10,621,000 for the period ended June 30, 1998 and reflects the
costs incurred to complete the FOTS under the Construction Services Agreements
with Ledcor. The gross margin of $1,659,000 for the period primarily represents
the 15% margin earned under the Construction Services Agreements.

     General and administrative expenses were $403,000 in the period and
represent the monthly fee of Cdn. $200,000 and direct costs reimbursed by Ledcor
under the Management Services Agreements.

     Income taxes provided for the period ended June 30, 1998 of $526,000
consist primarily of current taxes arising from our U.S. and Canadian
operations.

<PAGE>

     The results of operations for the period ended June 30, 1998 are not
comparable to the six-month period ended June 30, 1999 as operations commenced
on June 1, 1998 and revenues were derived primarily from the Construction
Services Agreements with Ledcor.

Period from February 5, 1998 to December 31, 1998
  (Operations commenced June 1, 1998)

     Revenue for the period from February 5, 1998 to December 31, 1998 was
$164,319,000. Revenue for this period was principally derived from the
Construction Services Agreements to complete the FOTS for Ledcor. This project
was completed in January 1999.

     Costs were $147,621,000 for the period from February 5, 1998 to December
31, 1998. Costs reflect primarily the costs incurred in completing the FOTS.
Costs as a percentage of revenue for the period were 90%, reflecting the costs
incurred plus 15% earned under the Construction Services Agreements. A portion
of the costs related to the FOTS were reimbursed without the 15% earned margin,
including costs associated with marine subcontractors.

     General and administrative expenses for the period from February 5, 1998 to
December 31, 1998 were $2,274,000, representing 1.4% of our revenues, and
consisting of the monthly fee of Cdn. $200,000 and direct costs reimbursed by
Ledcor under the Management Services Agreement.

     Income taxes for the period from February 5, 1998 to December 31, 1998 of
$5,643,000 consist primarily of current taxes arising from Worldwide Fiber's
Canadian and U.S. taxes of $2,599,000 and $3,044,000, respectively.

Telecommunications Division -- Ledcor Industries Limited
  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
developing the FOTS for Ledcor Industries Limited ("LIL").

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

     General and administrative expenses for the nine months ended May 31, 1998
were $710,240 representing 1.3% 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 the FOTS 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 LIL. 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 Limited
  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 the FOTS 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 engineering, design and building of the FOTS 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 LIL had entered into, which was the building of the FOTS and selling of
its components to third-parties. This was a different business than the business
previously conducted by the telecommunications division in which LIL would
construct and develop fiber optic systems on a contract basis for specific
telecommunications clients. Since this was a new business for LIL 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 1.5% 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 FOTS 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 LIL. 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.

Telecommunications Division -- Ledcor Industries Limited
  Five Months Ended August 31, 1996

     Revenues generated from contracts for the five months ended August 31, 1996
were $7,372,942. The revenues for this period are principally derived from the
fiber optics development between Calgary and Edmonton, Alberta.

     Contract costs were $5,768,543 for the five months ended August 31, 1996.
Contract costs for this period are primarily comprised of the design,
engineering and construction costs associated with the development project
between Calgary and Edmonton. Contract costs as a percentage of revenue for the
five months ended August 31, 1996 were 78%.

     General and administrative expenses for the five months ended August 31,
1996 were $90,993, representing 1.2% of revenues for the period. The general and
administrative expenses for this period are primarily derived from the overhead
necessary to commence the Calgary-Edmonton project.

     Income tax expense for the year ended August 31, 1997 represents a current
expense of $5,000 and a deferred expense of $681,000, using an effective tax
rate of 46%. As a division, we would have been consolidated within the tax
returns filed by LIL. 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

     At June 30, 1999, we had working capital of $167,910,000, including
$86,812,000 in cash or cash equivalents.

     Cash used in operations during the six months ended June 30, 1999 totaled
$49,824,000. We have an aggressive business plan to build out the network in the
United States and Canada that will require a significant investment in the
development of fiber and conduits held for sale, grant of indefeasible
rights-of-use, swap or lease and the purchase of transmission facilities. We
anticipate that we will continue to experience negative cash flow (after capital
expenditures) as we build out the network.

     In addition to the fiber assets contributed by Ledcor, we formed a capital
plan in 1998 to develop approximately 12,900 route miles. The plan and the
implementation of bandwidth services contemplate capital expenditures of
approximately $1.26 billion through 2001. This plan includes the building of
five intra-city networks ("city rings") in Canada and the installation of
electronics and transmission equipment along our entire terrestrial network,
commencing with the Vancouver-Detroit segment during the third and fourth
quarters of 1999. This plan does not include the Hibernia project, which is
discussed below. The following table describes funding sources contemplated by
the plan:

  Net proceeds from the $500,000,000 12% senior notes due 2009
    (the "Notes") .............................................    $484,000,000

                                                                 $1,260,000,000
                                                                 ==============

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

(1)  We anticipate that up to $150 million may be available under our planned
     bank credit facility.

     Consistent with our strategy to create a low-cost position, we have
agreements, subject to terms and conditions we consider customary, with
co-developers and participants. We have received, in the aggregate to date,
commitments of approximately $480,000,000 in cash to fund the completion of
segments of our terrestrial network from co-developers and participants.
Approximately $138,000,000 of the $480,000,000 is associated with revenue from
construction services we are providing to two customers under which we will earn
a specified margin and also retain dark fiber. The remainder of the $480,000,000
is derived from the sale, IRU or lease of fiber and conduit and additional
construction services we are providing to third parties along network segments
we are developing ourselves. We intend to enter into additional arrangements
with co-developers and participants, prior to completion of the network in 2001.

     We expect to obtain the balance of the funding necessary to complete our
terrestrial network and to implement our bandwidth services strategy from (1)
the cash remaining from the notes and the 1998 Notes and (2) our planned bank
credit facility. We have accepted a commitment letter from a bank lender which
contemplates that up to $150,000,000 could be made available to us in the form
of revolving credit borrowings. See "Description of Other Indebtedness--Proposed
Worldwide Fiber Credit Facility." We expect the facility to close in the fourth
quarter of 1999.

     We anticipate that these funding sources will provide us with sufficient
capital to complete our terrestrial network and to implement our related
bandwidth services strategy. However, because the cost of developing our network
and implementing our bandwidth services strategy will depend on a variety of
factors, many of



                                      -43-
<PAGE>

which are beyond our control, including changes in the competitive environment
of our current and planned markets, we expect that our actual costs may vary
materially from those currently budgeted. In the event that our actual costs
exceed our current budget or we do not have the funds we anticipate, we have the
ability to adjust the number or sequence of segments we develop.

     On September 9, 1999 we completed a private placement of our convertible
preferred shares for $345,000,000. See "Description of Our Recently Completed
Private Equity Placements." Of this amount, $45,000,000 was used to repurchase
certain of our shares held by an affiliate of our parent with the balance to be
used in the manner described below.

     The plan described above does not include the Hibernia transatlantic fiber
optic cable project. We estimate the total cost of this project to be
approximately $850,000,000. We will use $300,000,000 of the proceeds from our
recently completed private equity placement to fund the equity portion of the
cost of construction of the Hibernia project. We currently expect that the debt
component of the total cost will be approximately $550,000,000, and we have
entered into a project financing commitment letter with Goldman Sachs Credit
Partners LP, DLJ Capital Funding, Inc. and Credit Suisse First Boston. Under the
project financing commitment, it is anticipated that the lenders will provide up
to $600,000,000 in debt financing to one of our subsidiaries, non-recourse to
Worldwide Fiber. See "Description of Other Indebtedness - Proposed Hibernia
Credit Facility"

     We expect to pursue opportunities in addition to our planned network.
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 the completion of construction for the remainder of our planned network
development, the implementation of our bandwidth services strategy, the Hibernia
project or for other opportunities on a timely basis or on terms that are
acceptable to us, or at all.

Impact of Year 2000

     The Year 2000 problem impacts computer programs and hardware timers using
two digits (rather than four) to define the applicable year. We rely on our
computer systems and software applications in the operations and monitoring of
all major aspects of our business. Any of our computer programs that have
time-sensitive functions may recognize a date using "00" as the year 1900 rather
than 2000, which could result in miscalculations or system failures. A failure
of our computer systems, or those of Ledcor, major vendors, other material
service providers or customers, could have a material adverse effect on our
ability to develop our network and retain customers and on our ability to make
payment on the notes.

Risks of Year 2000 Issues

     We can not reasonably estimate the extent to which we may experience Year
2000 problems. We are reviewing our potential exposure to the Year 2000 problem
in the course of our Year 2000 program. We have not experienced any problems to
date related to the Year 2000 problem.

Description of our Year 2000 Program

     Our Year 2000 program began in 1997 while we were still a division of
Ledcor. We initiated a review of all computer related equipment and software.
This review encompassed all information and processing systems and related
equipment that were critical to the operations of our business. A list of
non-compliant equipment and software was developed and has resulted in the
replacement of certain equipment. This process was completed prior to the
commencement of our operations as Worldwide Fiber. The assets that were
transferred to us in the reorganization in May 1998 are, to the best of our
knowledge, Year 2000 compliant. Since we com-



                                      -44-
<PAGE>

menced operations in May 1998, we have required that all of our equipment
purchased be Year 2000 compliant. We are currently reviewing the work performed
by Ledcor and developing our own Year 2000 plan.

     Our plan includes obtaining written confirmation from Ledcor concerning the
status of Year 2000 compliance of Ledcor systems that were transferred to us in
1998. We will also review and test all equipment that we currently use. This
project began in the first quarter of 1999 and is expected to be completed by
the end of November 1999. This review will not delay or eliminate any other
information technology or related programs that are performed in the normal
course of our business.

     We will review and document the systems in use and determine the possible
affect on each system that would result from a systems failure due to the Year
2000 problem. The critical systems to be reviewed include, but are not limited
to: purchasing, payables, asset management, equipment management, payroll, sales
and receipts, management information systems, accounting and project management.
The review will include an inventory and testing of equipment that is critical
to the operations of our systems. Where testing is not possible, inquiry letters
will be sent to the suppliers in order to assess the Year 2000 status of their
systems. Significant suppliers will be contacted with a request for information
about their ability to provide services into the year 2000. The process is
expected to be complete by November 1999.

     Any equipment or software that is determined to be non-compliant as a
result of this review will be replaced as it is identified. The projected cost
of the Year 2000 assessment project is not expected to be material because
substantially all of the systems we acquired since our commencement were Year
2000 compliant.

     The extent to which our vendors, customers and service providers are Year
2000 compliant is not determinable at this time. We expect to receive
confirmations from these third parties before the end of September 1999 that
will allow us to determine the effect that any disruption of service will have
on our results of operations and financial position. We are developing a
contingency plan that will allow us to reduce or eliminate the disruption to our
business that a third party's noncompliance may cause.

State of Readiness

     We are implementing the Year 2000 plan and we plan to achieve the following
goals:

Contingency Plans and Costs to Address Year 2000 Issues

     We are currently developing plans, including a contingency plan, to assess
the likelihood of any Year 2000 issues and to address potential Year 2000
problems caused by a failure of our computer systems or the systems of Ledcor,
principal vendors, service providers and customers. These plans will include
increased staff awareness, advance preparation of invoices and payments and
backup of potential systems. Due to the relatively low number of transactions
processed by us, we will consider implementing a manual system for many
functions in the case of a failure of any of our systems.



                                      -45-
<PAGE>

     We have expended $25,000 to date, and we expect to spend no more than an
additional $150,000 to complete our Year 2000 readiness efforts. We may,
however, have to bear costs and expenses relating to the failure of Ledcor,
principal vendors, service providers and customers to be Year 2000 compliant on
a timely basis. No material Year 2000 issues have been identified to date
relating to third parties. Therefore, we cannot reasonably estimate costs which
may be required for remediation or for implementation of our contingency plans.

                                    BUSINESS

General

     We are a provider of technologically advanced fiber optic communications
infrastructure in North America using our state-of-the-art fiber optic network.
We recently have begun marketing bandwidth services and intend to provide these
services by the end of the year. Our present and targeted customer group is
communications carriers, ISPs and large corporations with enterprise network
needs. In January 1999 we completed construction of the FOTS, a 5,068 route mile
fiber optic network development across Canada and the Northern United States.
Our interests include: (1) a 2,735 route mile segment (approximately 36,000
fiber miles) of the FOTS from Vancouver to Detroit, via Calgary, Winnipeg,
Minneapolis/St. Paul and Chicago and (2) an additional 2,333 route miles
(approximately 38,000 fiber miles) along the FOTS extending from Seattle to
Detroit and Edmonton to Toronto. In May 1999, we completed construction of the
segment of our network that extends from Seattle to Portland. Together this
fiber forms the initial backbone of our high-bandwidth fiber optic
communications network and related infrastructure in North America.

     Our network is being developed to satisfy increasing demand for fiber optic
capacity for the transmission of data, voice and video generated by
high-bandwidth communications and the requirements of new entrants to the
telecommunications business. Our network consists of fiber optic strands
installed in protective conduit buried along diverse ROW and includes related
infrastructure such as regeneration shelters. In order to expedite completion of
our network, we install sufficient fiber along our builds to allow us to swap
fiber with other developers and carriers where we believe it is more economical
or time efficient to swap for, rather than construct, fiber assets. When
complete, our terrestrial network is expected to cover approximately 21,600
route miles in North America (comprising in excess of 1,000,000 fiber miles).
The anticipated terrestrial network footprint initially will include two primary
east-west routes and three primary north-south routes. In addition to our long
haul builds, we intend to build city rings to enhance the attractiveness of our
network. We are currently developing a 67-mile Seattle metropolitan network and
intend to build city rings in five additional cities: Toronto, Vancouver,
Montreal, Ottawa and Calgary. In addition, we are developing a 7,600 mile
transatlantic fiber optic system and have contracted with Tyco Submarine Systems
Ltd. for its construction.

     We believe that our network's transmission capacity, route diversity,
national route design and connectivity, together with our status as an
independent developer and carrier's carrier, will enhance the marketability of
the network as a primary or redundant route. We believe the network will be
attractive to communications carriers, ISPs and large corporations with
enterprise network needs.

     We plan to realize the value of the network through the sale, grant of
indefeasible rights-of-use ("IRU"), lease or swap of dark fiber strands and
conduit. The North American footprint of our network allows us to offer
customized products to our customers by providing fiber or conduit on a
segmented basis or throughout our entire network. We have commenced the process
of adding the necessary transmission equipment to enable us to provide bandwidth
services to carriers and other service providers along the route from Seattle to
Toronto via Vancouver, Calgary, Winnipeg, Minneapolis/St. Paul, Chicago and
Detroit. Beginning the first quarter 2000, we intend to install the necessary
transmission equipment to provide the services along multiple segments of our
network in North America. We have selected Nortel Networks, Newbridge Networks
and Fore Systems as major suppliers of transmission equipment. We may also swap
bandwidth, enter into joint ventures or purchase bandwidth to enhance the
connectivity of the network.

     We generally reduce the capital risk necessary to build and develop the
network by pre-selling sufficient strands and conduit to cover approximately 50%
of our anticipated construction cost on a condominium or co-development basis.
We also exploit certain construction, technological and ROW expertise and
agreements. The "condominium" concept comes from the construction development
industry. Our condominium development strategy allows multiple participants to
purchase or lease fiber or conduit from an experienced developer



                                      -47-
<PAGE>

capable of delivering a pre-designed fiber optic system on schedule at a fixed
price. Generally, we install more fiber along any specific route than one
customer would typically install for its own use. Our condominium style of
development encourages participants to commit to purchasing or leasing fiber or
conduit during the initial stages of construction. If participants commit to a
build early enough, they may have more flexibility with regard to choice of
fiber and other infrastructure decisions. This development strategy reduces our
risk and may allow participants favorable pricing for fiber assets. To expedite
route development or decrease development risk, we may enter into co-development
or swap arrangements. Under a co-development arrangement, the co-developer funds
a portion of the project in exchange for receiving fiber or conduit assets or an
equity position in that segment.

     We will continue to construct fiber optic networks for third parties on a
contract basis when a project will allow us to retain fiber or conduit assets,
including through IRUs. We plan to construct these networks only on routes that
complement and reduce the costs of completing our network or enhance our ability
to make a sale, grant of IRU, lease or swap of network capacity or the provision
of bandwidth services.

Network Construction Experience

     We have been designing, engineering and constructing telecommunications
networks for 12 years, first as the telecommunications division of, and since
May 1998 as a separate subsidiary, of our parent, Ledcor. The FOTS was
originally engineered, designed and partly constructed by our predecessor. As
the successor to Ledcor's telecommunications division, we have acquired all of
its construction assets, certain fiber assets and construction contracts, its
management and personnel and the expertise gained from various
telecommunications network construction projects. In addition to the
construction and development of the FOTS, Ledcor, through its telecommunications
division, has a long history of successfully designing, engineering and
constructing networks for third parties. Ledcor's telecommunications division
has installed more than 10,000 route miles of telecommunications networks for
major telecommunications carriers. In the summer of 1996, Ledcor began its first
project as a developer of fiber optic networks by designing, engineering and
building a fiber optic network from Calgary to Edmonton. In addition to
retaining six fibers for its own account, Ledcor pre-sold the remaining fibers
on the project to Sprint Canada, AT&T Canada Corp. and fONOROLA, Inc.

Market Opportunity

     The North American telecommunications industry has been characterized by
significant demand for high-bandwidth communications services. According to an
industry survey by The Yankee Group:

     o    voice and data telecommunications services revenue in the United
          States is expected to grow at a compounded annual growth rate of
          approximately 8%, from approximately $167 billion in 1997 to
          approximately $241 billion in 2002,

     o    data telecommunications services revenue is expected to grow at a
          compounded annual growth rate of approximately 26%, from approximately
          $15 billion in 1997 to approximately $47 billion in 2002, and

     o    carriers' carrier telecommunications services revenue, which our
          bandwidth services strategy is specifically intended to target, is
          expected to grow at a compounded annual growth rate of approximately
          60%, from approximately $1.2 billion in 1997 to approximately $12.3
          billion in 2002.

     Our network is designed to provide our customers with secure, independent
transmission facilities and sufficient capacity on a local, regional or national
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:



                                      -48-
<PAGE>

     o    Innovations and advances in transmission technology. Technological
          innovations are increasing both the supply of and demand for
          high-bandwidth telecommunications transmission capacity while the
          desire to obtain services from a reduced number of vendors and the
          trend towards providing end-to-end digital services continue to drive
          increased integration of voice, data and video services. Innovations
          in optics technology have increased 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. We
          are developing our advanced fiber optic network to meet the increasing
          demand for high-bandwidth capacity.

     o    Increasing demand for high-bandwidth applications, largely driven by
          the increase in Internet traffic. There is and will continue to be a
          significant growth in demand for Internet, long distance, local loop
          data and video services. 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. Prices for cellular services have
          decreased, resulting in increased demand for these services. It is
          expected that video conferencing, digital television and other
          multimedia applications being developed will continue to increase
          demand for bandwidth. We believe our high-bandwidth network is well
          positioned to capture some of this growing demand.

     o    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. Although the
          Federal Communications Commission ("FCC") has not granted any Regional
          Bell Operating Companies ("RBOCs") the authority to provide in-region
          inter-LATA telecommunications services and it is uncertain when it
          will do so, the Telecommunications Act of 1996 has opened local
          markets to competition and defined a path for the RBOCs to compete in
          long distance markets. Our high-bandwidth platform allows both new
          entrants to compete in this market and existing service providers to
          expand into new markets. We believe our network will offer an
          attractive alternative to network construction and ownership for these
          carriers.

Business Strategy

     Our strategy is to be a leading independent provider of technologically
advanced dark fiber and related infrastructure and high-bandwidth fiber optic
transmission capacity. The key elements of our business strategy include:

     o    Developing and building a technologically advanced fiber optic
          network. The network is designed with the most advanced, commercially
          available technology to provide the highest levels of reliability,
          security and flexibility demanded by our customers. We intend to use
          our fiber optic design, engineering and construction expertise to
          enhance and broaden the desirability of our network.

     o    Maximizing route diversity and connectivity of the network. The
          footprint of our network is designed with the input of our customers
          and will connect many of the major population centers in North
          America. We believe that route diversity and connectivity increase the
          network's inherent value. We intend to participate in international
          cable construction projects to expand the reach, connectivity and
          attractiveness of our network. Further, our expanding footprint should
          enhance the value of the network by enabling us to target a broad
          range of customers by offering participation on a local, regional,
          national or international basis.



                                      -49-
<PAGE>

     o    Reducing capital risks and creating low cost position. We generally
          commence construction of a network segment when we have pre-sold
          sufficient strands and conduit to cover approximately 50% of our
          anticipated cost of that segment. In some segments, we may seek a
          co-developer to fund a portion of the project in exchange for
          receiving fiber or conduit assets or an equity position in that
          segment. We believe that our network will have a low cost basis for
          the following reasons:

          --   as a result of our condominium development strategy, we generally
               install 144 fibers (or a significantly higher number of fibers in
               high demand areas), reducing the per fiber mile cost to construct
               and operate our network,

          --   we use a patented railplow to install fiber optic cable along
               rail lines quickly and cost effectively,

          --   we retain fiber assets for our own use along routes where we
               complete third party construction, and

          --   we believe that certain of our current ROW, licenses, permits and
               franchises are, and others currently being negotiated will be,
               valuable assets that would be costly and difficult for others to
               procure or replicate in the future.

     o    Realizing value of the network. As an independent provider of fiber or
          conduit, we believe that telecommunications carriers will be more
          likely to purchase or lease facilities from us than from their
          competitors that are telecommunications carriers or are affiliated
          with one. We intend to realize the value of our network through:

          --   sales, grants of IRU, leases on a short or long term basis, or
               swaps of network assets, and

          --   the provisioning of bandwidth services.

     o    Providing bandwidth capacity. We have commenced the process of adding
          the necessary transmission equipment to provide bandwidth services to
          carriers, ISPs and large corporations with enterprise network needs.
          We also intend to offer our customers low cost bandwidth and the
          flexibility to control their own service platforms so that they choose
          to buy services from us rather than build these service capabilities
          themselves or purchase them from another bandwidth provider.

     o    Allowing for technological upgrades and additional capacity. We
          generally install at least one additional conduit along each segment
          that we develop, allowing for network expansion and permitting
          technological upgrades. Our network's optical design will enable us to
          upgrade installed equipment or to add new technology to any segment of
          the network.

     o    Capitalizing on management experience. We have assembled and will
          continue to build a strong management team comprised of executives
          with extensive experience in the design, engineering construction and
          maintenance of fiber optic networks, general telecommunications
          infrastructure and telecommunications bandwidth services. The
          management team also has considerable experience in the development
          and financing of growth stage international companies.

The Network

     Our anticipated terrestrial network footprint includes: (1) a North
American long-haul fiber optic network and (2) city rings. Upon completion of
these builds, our network will cover approximately 21,600 route miles
(comprising in excess of 1,000,000 fiber miles). The footprint will consist of
the following:



                                      -50-
<PAGE>

     o    a North American long-haul fiber optic network including: (1) two
          primary east-west routes, running from Vancouver to Halifax and
          Sacramento to Boston, and (2) three primary north-south routes,
          running along the West Coast, the Mississippi River valley and the
          East Coast, and

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

In addition, we plan to expand our network outside of North America and have
recently announced plans for our transatlantic fiber optic cable project.

     We expect to complete the development of our network in 2001. Our policy on
major builds is to install an average of 144 fibers and three conduits. In high
demand areas, we may install 264 fibers or more and additional conduit in order
to meet projected demand. The additional fiber assets installed along our builds
enable us to swap fiber for fiber in other geographic areas both in the North
American market and internationally. Fiber swaps should allow us to complete the
network expeditiously and cost effectively by, among other things, reducing the
need and time required to obtain additional ROW.

     Although the following table summarizes our current plans for completing
the terrestrial network, the segments, scheduled completion dates and proposed
participants/co-developers/swaps/joint ventures listed below may change due to
market and other circumstances, some of which may be beyond our control:

Future Network Expansion and Infrastructure Development

     We believe there may be opportunities in the future to continue the type of
network development we are currently deploying in North America. In addition to
further North American development and our announced transatlantic fiber optic
cable project, future network development locations could include areas of
Europe, South America and Asia. We have developed our marine capability through
our activities as contract manager on the NorthStar submarine cable build from
Anchorage, Alaska to Pacific City, Oregon. We believe that these further
developments will enhance the connectivity and value of our network.

     We believe that Hibernia represents an opportunity to connect our existing
North American terrestrial network to future European customers because it will
allow us to provide an undersea cable system link between and among Halifax,
Canada; Boston, Massachusetts; Dublin, Ireland, and Liverpool, England. Hibernia
is expected to be completed by the first quarter of 2001. On June 18, 1999, we
entered into a supply agreement with Tyco Submarine Systems Ltd. ("Tyco")
whereby Tyco will serve as the primary contractor for Hibernia. The initial
contract price is approximately $607 million. The Company has paid $60.7 million
in advance payments to Tyco.

     We also believe there is an opportunity to operate, for multiple network
participants, carrier hotel facilities and other network infrastructure near
points-of-presence ("POPs") that are presently at or near capacity. Our parent,
Ledcor, currently constructs network infrastructure for us, including
regeneration shelters and access boxes. We believe our and our parent's
collective operations and construction expertise will enable us to develop
carrier hotel facilities.

Network Design and Infrastructure

     Network Technology

     The network uses state-of-the-art fiber optic strands which allow for the
high speed, high quality transmission of data, video and voice communications.
Fiber optic systems use laser-generated light waves to trans-



                                      -53-
<PAGE>

mit data, video and voice in digital formats through ultra-thin strands of
glass. Fiber optic systems are generally characterized by large circuit
capacity, good sound quality, resistance to external signal interference and
direct interface to digital switching equipment or digital microwave systems. We
plan to install an average of 144 fiber optic strands on major builds throughout
the network. In high demand areas, we may install 264 fibers or more in order to
meet anticipated demand.

     Each fiber optic strand is capable of transmitting significantly greater
bandwidth than traditional copper cables or older fibers. The advanced technical
operating characteristics of the network will enable us to provide
technologically advanced dark fiber to our customers at low cost by permitting
higher capacity transmission over longer distances between regeneration and
amplifier facilities than can be provided by less advanced fiber systems. Using
current dense wave division multiplexing ("DWDM") fiber optic transmission
technology, a single pair of fiber optic strands used in the network can
transmit up to 320 gigabits of data per second ("gbps"), the equivalent of
approximately 4.2 million simultaneous voice conversations.

     We anticipate that continuing developments in compression technology and
multiplexing equipment will increase the capacity of each fiber optic strand,
providing more bandwidth carrying capacity at relatively low incremental cost.
Our network is compatible with the highest commercially available transmission
capacity, i.e., OC-192, and can accommodate advanced capacity-intensive data
applications such as Frame Relay, ATM, multimedia and Internet-related
applications. Our network will allow us to offer end-to-end fiber optic capacity
compatible with SONET Ring architecture. This design routes customer traffic in
either direction around its ring design, assuring that fiber cuts do not
interrupt service to network customers. Our network is also capable of
supporting DWDM.

     Bandwidth Services Technology

     The provision of bandwidth services requires optical and ATM-packet
switching technology. A backbone of DWDM optical equipment provides optical
services as well as the transport for the lower speed services that are
delivered on an ATM-packet switching technology.

     Optical Technology

     Our network's optical design will enable us to upgrade installed equipment
or to add new technology 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 within twelve months. We intend to utilize optical
ring protection devices where a customer requires redundant services.

     ATM-Packet Switching Technology

     We believe that most of our bandwidth services customers will use our
state-of-the-art high availability ATM layered architecture. The initial layers
will consist of high capacity core switches and a number of multi-service
platform ("MSP") switches located at each POP along the network.

     The initial core switches will have a throughput capacity of 40 gbps and
network link speed of 2.5 gbps. We anticipate these switches will be upgradeable
to 10 gbps network links and total throughput capacity of 480 gbps at major POP
locations.

     The core switches will provide:

     o    ATM customer link connections at speeds of 155 megabits of data per
          second ("mbps") to 2.5 gbps,



                                      -54-
<PAGE>

     o    network to network interface ("NNI") links to the MSP switches, and

     o    high speed private line services at 155 mbps, 622 mbps and 2.5 gbps.

     The MSP switches will be linked to the core switch via redundant 622 mbps
ATM NNI connections. The initial MSP switches will have a capacity of 12 gbps
and may be upgraded to 50 gbps to meet customer requirements. These switches
will allow us to provide a wide range of voice and data services. The inherent
capabilities of the MSP will support the following services:

     o    low speed ATM at DS-3,

     o    private line services at DS-3, OC-1 and OC-3 (155 mbps),

     o    IP Internet connectivity,

     o    video services,

     o    transparent switched voice (64 kilobits of data per second ("kbps")),

     o    compressed switched voice (8-16 kbps),

     o    LAN interconnect,

     o    high speed Internet delivery via xDSL, and

     o    digital wireless services such as local multipoint communication
          services.

     Network Operations Center

     Our Network Operations Center ("NOC") will be the human service connection
between our customers and the technology that ultimately delivers their
services. We are currently designing and plan to construct our NOC in Vancouver.
We intend to enter into an agreement with Nortel to provide redundant network
management services on a transitional basis. The NOC will allow us to provide
the following services:

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

     o    providing network management for the optical and ATM elements,

     o    providing POP and customer record management, and

     o    providing circuitry for customer and internal circuits.

     We are using a design based on IP technology that will integrate 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
certain management services to our customers in a secure and reliable way.

Network Construction

     The network is designed to access areas of significant end user
telecommunications traffic, as well as the POPs of most interexchange carriers
("IXCs") and the principal incumbent local exchange carrier ("ILEC") central
offices in each city on the network, in a cost-efficient manner.

     Upon commencement of the development of a network segment, our development
staff is responsible for obtaining the necessary permits and ROW. In certain
jurisdictions, a construction permit is required. We strive to obtain ROW on
favorable terms that afford us the opportunity to expand the network as business
develops. ROW are typically leased or licensed under multi-year agreements with
renewal options and are generally non-exclusive. We obtain ROW from entities
such as railroads, pipeline owners, local government transit authorities,
municipalities, highway authorities, and other utilities.

     We establish general requirements for the design of each segment of the
network. In-house or external engineers render drawings of the contemplated
segment and the required deployment. Construction and installation may be
completed by us or provided by independent subcontractors. Our personnel provide
project management services, including contract negotiation, construction, and
testing and certification of all facilities. The construction period for a
segment varies, depending upon the number of route miles to be installed.
Testing and delivery of a new segment typically takes place within 30 days of
the completion of construction.

     Our network installation process along railroad ROW combines traditional
railroad activities and modern engineering and building techniques. We generally
install conduit and fiber on railroad ROW with the patented railplow. When the
railplow is in use, a plow car travels along the railroad track and
simultaneously plows a slot to bury multiple conduit with approximately 42
inches of cover, buries a warning tape approximately one foot from the surface,
and returns the land to its original contour. A railplow can cover between five
and ten miles a day, depending on the availability of track time and the
severity of the terrain. Other loaders on rail carry the conduit and other
construction materials needed to construct the fiber route and are designed to
continuously feed supplies to the railplow. Installation of conduit and fiber
utilizing a railplow is completed by an installation team. The team may consist
of numerous specialized crews, such as a pre-rip crew, a plow crew, a cable
jetting crew, and a splicing crew. These crews, in aggregate, may include 60 or
more persons.

     Ledcor developed the railplow because traditional plow trains are both
expensive to purchase or lease and inefficient when attempting to install fiber
on busy railroad routes where available track time comes in small blocks and on
relatively short notice. The plow train and supply cars frequently must travel
several miles down the route into sidings to permit regular railway traffic to
pass, during which time the fiber optic cable must be unrolled and then
re-rolled to avoid a splice. The railplow allows us to move on and off the
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 certain circumstances, our ownership of
this company would be subject to change and our license would become
non-exclusive. See "Transactions with Our Parent--Description of Reorganization
and Related Agreements."

     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 certain 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



                                      -56-
<PAGE>

tunnels underneath the river or obstruction and feed the conduit through the
tunnel. Through our relationship with Michels Pipeline Construction Inc., an
industry leader in directional drilling, we believe we have a competitive
advantage over other builders lacking a high degree of directional drilling
expertise.

     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. We accomplish this through the use of access boxes that are
installed along the network at approximately four to five mile intervals. The
access boxes also allow us to make repairs, replace fiber and install 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 40-75 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. The
current generation of equipment may be upgradeable to 160 separate OC-192 (10
gbps) transponder channels per fiber, or 1.6 terabits per second ("tbps") of
capacity per fiber pair. 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.

     The ATM-packet switching elements use multiple, diverse or redundant
optical channels to connect the core switches together. A hierarchical source
routing protocol called Private Network--Network Interface ("PNN") has been
adopted to provide the scalability and restoration capabilities required to
deliver the highest levels of reliability and availability. With this
implementation we are able to utilize the redundant path between the switches to
deliver a secondary set of services that do not require the high reliability, or
may be scaled down in the event of a link or nodal failure.

Rights-of-Way

     To implement our business plan successfully, we must obtain licenses and
permits from third party landowners and governmental authorities and complete
certain 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. We may lease underground conduit and other ROW
from entities such as utilities, railroads, highway authorities, local
governments and transit authorities. ROW agreements and permits provide us with
a contractual interest and do not create an interest in land. See "Risk
Factors--Need for ROW."

     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. Many ROW will be obtained just prior to the arrival of crews and
contractors. Alternative ROW for certain route miles must be identified,
negotiated and obtained in the event that the original route cannot be secured.

     It is also possible to obtain ROW in bulk. The majority of the ROW for the
FOTS was obtained from two Canadian railways. In June 1999, we announced
agreements with IC and CN 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. See "Description of IC and CN Agree-



                                      -57-
<PAGE>

ments." We believe these ROW will be valuable to us, particularly with the
advantages of the railplow and the ROW's geographic location. The ROW obtained
from IC and CN may be subject to legal challenge. See "Risk Factors -- Need for
ROW."

Products and Services

     In connection with the development of our network, we offer customers a
range of products and services which enable us to provide customized solutions.
Our products and services include:

     Dark fiber and conduit for sale or grant of IRU. 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 $2,000 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 lease, usually of 10 to 20 years, with an
option period for the lessee to renew at lower rates. 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.

     Dark fiber and conduit for swap. We swap some of our excess fiber or
conduit with other developers and carriers for fiber assets along routes where
excess fiber assets exist and where we believe it is more economical or time
efficient to swap for, rather than construct, fiber assets.

     Construction services supporting the development of our network. We are
continuing to construct 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.

     Bandwidth services. We have commenced the process of adding the necessary
transmission equipment to enable us to utilize the fiber installed on the
existing installed fiber routes to provide bandwidth services to carriers, other
service providers and large corporations with enterprise network needs along the
FOTS. Beginning the first quarter 2000, we intend to install the necessary
transmission equipment to provide the services along multiple segments of our
network in North America.

     The services we intend to offer through our sale of bandwidth capacity
include:

     Optical Transmission Services. DWDM technology in our network will allow 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 will install their own
switching and routing equipment and will have the choice of installing their own
protection equipment or use optical protection supplied as part of our service.
The following are the service highlights:

     o    transparent OC-48 under IRU or lease,



                                      -58-
<PAGE>

     o    transparent OC-192 under IRU or lease,

     o    optical ring protection,

     o    linear routes available, and

     o    add/drop along route.

     Private line services. We intend to offer fixed amounts of point-to-point
capacity across the network. We believe our service will have 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 grant of IRUs or leases and will provide transparent
connectivity up to OC-12.

     Virtual switching solutions. We intend to provide customers with voice
trunking services that can be configured for sale as minutes of use. These
services will enable these customers to originate and terminate long distance
telephone calls connecting to ILECs or to competitive local exchange carriers
("CLECs") with switched transport through our ATM network. Because we will be
able to offer these connections on an as needed basis we are able to offer
extremely competitive and flexible pricing. In addition, we will be able to
provide a simple bill to our customers. The services we intend to offer include:

     o    DS-1 to OC-3 structured services,

     o    DS-0 switching and billing for usage,

     o    transparent local interface,

     o    SS7 signaling transport, and

     o    advanced services, including compression.

     Packet-based data services (IP Transport and ATM). We intend to provide
customers with 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.

     ATM service will include the following service attributes:

     o    DS-3 to OC-48 interface rates,

     o    all 5 classes of ATM service: UBR, ABR, VBRrt, VBRnrt and CBR, and

     o    switched virtual circuits available on customer premises equipment
          edge.

     IP transport will include the following service attributes:

     o    protocol supports including PNN, ATM and packet over SONET,

     o    nodes in all major Internet-network access points, and

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

Sales and Marketing

     Network

     Our approach is to market to customers on a local, regional and national
basis. We market participation in segments of our network through personal
contacts and relationships with prospective customers, who consist primarily of
large telecommunications companies. Our current targeted customer base is
comprised of approximately 200 companies. We believe that we are known to most
of our target customer group and that we have good relations with them. Our
relationships are cultivated and maintained by a marketing and sales staff based
in 15 offices across North America. Most of our marketing and sales team have
prior industry experience with telecommunications companies such as MCI
Worldcom, Sprint, AT&T, 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 believe that relationships established by our sales team and
management result in interactive exchanges that help us to design and market our
network in response to the needs of our potential customers. We are also able to
identify potential participant and co-development customers who initially
approach us because of our reputation and experience in the design, construction
and development of fiber optic facilities.

     Bandwidth Services

     We commenced marketing our bandwidth services in the second quarter of 1999
to targeted customers through a number of focused direct sales methods. Our
strategy is to target customers who have a need for bandwidth services in areas
covered by those portions of our network on which we initially will be
installing transmission equipment. As this equipment is deployed across our
network, we expect that the number of our target customers will become larger
than for our network services. We will be marketing a broad and technically
advanced range of bandwidth products and services. Consequently, we are
developing a dedicated sales and marketing team with the necessary distinct
expertise. This team is expected to grow to 15 members by the first quarter of
2000 and will be located in offices throughout North America.

     In addition to our direct sales efforts, contacts made when marketing our
network services identify highly qualified prospective bandwidth customers. We
also receive referenced introductions from our suppliers when bandwidth
requirements are identified while they are making customer contacts in the
process of doing their business. Our experienced sales team will qualify
potential customers from their personal contacts and direct sales efforts.

Customers

     We are focused on providing our broadband fiber optic network and bandwidth
services to communications carriers, ISPs and large corporations with enterprise
network needs. Our targeted customers include a broad range of companies, such
as:

     o    ILECs,

     o    CLECs,

     o    ISPs,

     o    long distance companies (North American and international),

     o    RBOCs,



                                      -60-
<PAGE>

     o    IXCs,

     o    multi-service operators,

     o    local multipoint distribution service providers, and

     o    large corporations with enterprise network needs.

     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.

     As of September 30, 1999, we had finalized, or were in the final stages of
negotiating, agreements for the sale, lease or IRU of dark fiber or conduit with
approximately 30 communications carriers and owners of corporate networks. In
addition, we are currently in various stages of negotiating similar agreements
with a number of other potential customers. Described below are a number of our
arrangements with communications carrier customers.

     GST. In August 1998, we entered into agreements with GST
Telecommunications, Inc. relating to the construction and marketing of a
multiple conduit fiber optic system between Portland and Sacramento and the
installation of one fiber optic cable. We will have a reciprocal maintenance
arrangement with GST during the term of the agreement. GST will receive
approximately 50% of the total fibers and will be entitled to use 50% of the
capacity of the regeneration facilities. We have a reciprocal two-year option to
exchange fiber assets with GST along specified portions of the network for fiber
assets owned by GST located in California.

     In April 1999, we entered into an additional agreement with GST for the
design, engineering, construction and installation by them of a multiple conduit
fiber optic system between Mira Mesa and San Diego. Upon completion of this
segment we will receive approximately 50% of the total fibers and conduits and
be entitled to use the associated regeneration facilities. In addition, we
agreed to exchange with GST conduit from our Seattle city ring for segments of
GST's network route in Southern California.

     Williams. In December 1998, we, together with GST as co-developer, entered
into a development agreement with Williams Communications, Inc. for the design,
engineering, construction and installation of a multiple conduit fiber optic
system between Portland and Sacramento which is expected to be completed in the
fourth quarter of 1999. The parties expect to enter into a maintenance agreement
in which we, together with GST, will agree to maintain the multiple conduit
fiber optic system.

     Level 3. In December 1998, we entered into a construction services
agreement with Level 3 Communications, Inc. relating to the construction of a
multiple conduit fiber optic system between Montreal and Buffalo. In connection
with this agreement, we will be paid a fee and retain dark fiber on this build
through an IRU.

     In February 1999, we entered into an agreement with Level 3 for the
construction and installation of a multiple conduit fiber optic system in the
greater Seattle area. In connection with this build, we will be paid a fixed fee
for each route mile, plus amounts for additional services and materials. In May
1999, we also agreed with Level 3, under a co-development agreement to design,
engineer, install and construct a multiple conduit fiber optic system between
Springfield, Oregon and Anderson, California.

     Qwest. In February 1998, we entered into a participation agreement with
Qwest Communications International Inc. relating to the design and construction,
by us, of a multiple conduit fiber optic system, approximately 199 miles long,
between Seattle and Portland. In February 1999, we amended the agreement to add
ad-



                                      -61-
<PAGE>

ditional city ring segments in the greater Seattle area. Qwest will pay us a
fixed fee per route mile, plus amounts for additional services and materials,
including the installation of additional fiber optic network infrastructure.

     AT&T Canada. We have agreed to sell to AT&T Canada dark fiber and related
regeneration shelters within five segments of the network to be designed and
constructed by us. The five segments comprise approximately 1,100 route miles
and will be installed between Calgary and Edmonton, Detroit and Toronto, Toronto
and Ottawa, Ottawa and Montreal, and Montreal and Quebec City. The expected
completion date of these segments is December 1999. We will be responsible for
the operation and maintenance of the fiber optic cable and regeneration shelters
following completion.

     Telus. We have agreed to grant an IRU to BCT. Telus Communications Inc.,
now known as "Telus", for dark fiber and related regeneration facilities within
a multiple conduit fiber optic system to be designed and constructed by us. The
approximately 175 mile long project will run from Vancouver to Seattle. We will
lease the dark fibers for a fixed price per fiber mile for the shorter of 25
years or the useful life of the assets, subject to renewal, and Telus will pay
additional amounts for its pro rata share of services and maintenance costs. The
expected completion date for the project is the third quarter of 2000. We will
be responsible for the operation and maintenance of the fiber optic cable system
and regeneration shelters for the duration of the lease.

     In the second quarter of 1999, we entered into agreements with Telus for
the design and construction of multiple conduit fiber optic systems and sale of
dark fiber on segments from Edmonton to Toronto, from Detroit to Halifax through
Toronto, Ottawa, Montreal and Quebec City, and connecting segments from Toronto
to Buffalo, Albany and Montreal. Construction of the segments is scheduled to be
completed by December 2000. Telus has an option to acquire additional dark fiber
on segments from Calgary to Edmonton and Albany to New York City. For the route
which connects Detroit to Halifax, we will be responsible for the maintenance
and for the Edmonton to Toronto route, the parties have agreed on principles to
be included in the maintenance agreement.

     Metromedia. We entered into an IRU exchange agreement with Metromedia Fiber
Network, Inc. in which Metromedia agreed to grant a multi-year IRU for dark
fiber in a segment between New York and Washington, DC. In exchange, we have
agreed to grant a comparable IRU to Metromedia in relation to segments from
Seattle to Portland, Portland to Pacific City and Albany to Montreal. We will
have a reciprocal maintenance arrangement with Metromedia during the term of the
IRUs.

     Call-Net. A subsidiary of Call-Net Enterprises Inc. has agreed to purchase
conduit and related infrastructure running between Seattle and Portland which we
are designing and constructing. We completed construction in May 1999. We will
maintain the conduit and related infrastructure following completion.

     Pathnet. In March 1999, we entered into a co-development agreement with
Pathnet, Inc. for the design, engineering, construction and installation by us
of a multiple conduit system, approximately 1,100 miles long, between Denver and
Chicago. The first segment, Chicago to Omaha, is scheduled to be completed in
1999 with the second segment, Omaha to Denver, scheduled to be completed by the
end of 2000. The parties expect to enter into a maintenance agreement in which
we will agree to maintain the multiple conduit system, including the portion of
the system to be held by Pathnet.

Suppliers

     The principal components of our network are fiber optic cable and conduit,
which are purchased 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.



                                      -62-
<PAGE>

     We purchase optical components and ATM-packet switches from third party
suppliers. Manufacturers generally require two to three months lead time for
both new systems and specific transponder cards. ATM switches and expansion
cards are generally available in four to eight weeks.

     We 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

     Fiber optic systems are currently under construction or development
throughout North America. The construction of these networks enables their
owners to sell or lease access to their networks to other communications
entities or large corporate or government customers. In addition, various
communications carriers already own fiber optic cables as part of their
communications networks. Accordingly, each of these parties could, and some do,
compete directly with us in the market for selling and leasing fiber capacity.

     There are currently at least four principal long distance fiber optic
networks in North America. We are aware that others are planning networks that,
if constructed, could employ advanced technology similar to that of the network.
These competitors may also sell fiber to other carriers and thus compete
directly with us for customers.

     Bandwidth services is an area that has seen a number of new entrants who
initially focus on the provision of bandwidth and other services on a wholesale
basis, promising independence from traditional or incumbent suppliers that
compete directly in the market at the retail customer level. In the recent past,
carriers such as Williams, Qwest, Global Crossing and Level 3, who initially
focused on the wholesale market, have entered the retail segment of the market,
or closely aligned themselves with a major retail service provider. These
companies continue to market wholesale services to their current customers while
also pursuing new customer opportunities.

     We anticipate that competition for our bandwidth services will come from
the above companies as well as IXC and DTI, which have not entered the retail
market. We believe our competitive advantage 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 independence, services designed for the
wholesale market and simple billing systems will enable us to gain a significant
position in this market niche.

     In the future, we may be subject to additional competition due to the
development of new technologies and increased supply of domestic and
international transmission capacity. The telecommunications industry is in a
period of rapid technological evolution, marked by the introduction of new
product and service offerings and increasing satellite transmission capacity for
services similar to those provided by us. For instance, recent technological
advances permit substantial increases in transmission capacity of both new and
existing fiber, and the introduction of new products or emergence of new
technologies may reduce the cost or increase the supply of certain services
similar to those provided by us. We cannot predict which of many possible future
products and service offerings will be important to maintain our competitive
position or what expenditures will be required to develop and provide such
products and services.

Employees

     As of August 31, 1999, approximately 700 full-time and seasonal people were
engaged in building the network. 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
agree-



                                      -63-
<PAGE>

ment with the Christian Labor Association of Contractors which expires on
February 28, 2000 and is automatically renewable unless either party gives prior
notice. We believe that our work force is highly capable and motivated and that
our relations with our employees are good. In connection with the construction
and maintenance of our fiber optic networks, we may use third-party contractors
to meet excess demand and harness local construction knowledge, some of whose
employees may be represented by other unions or covered by collective bargaining
agreements.

     The provision of bandwidth services will require a team of highly skilled
technical and sales personnel. Under our current plan we anticipate requiring a
total staff of 35 persons in network operations, billing and sales support by
the end of 1999. Most of this staff will be located in Vancouver, with
additional offices in Denver, Toronto and Washington, DC. New staff will be
added to existing Worldwide Fiber offices throughout Canada and the United
States as the network expands into new service areas.

Properties

     Our executive and administrative offices are located in Vancouver, British
Columbia. Our principal sales, engineering and operations offices are located in
Toronto and Denver.

     Ledcor leases the Vancouver office premises to us under agreements that
expire in 2002. Ledcor owns the facilities (approximately 40,600 square feet) in
Toronto and makes it available to us. An additional 24,130 square feet in the
building in Toronto is leased by Ledcor to a number of tenants and will become
available to us from time to time if it is required. WFNI leases the space
(approximately 4,200 square feet) in Denver under an agreement that expires on
October 31, 2001. We also currently lease offices or property in Blaine, WA,
Vancouver, WA, Snohomish, WA, Portland, OR, Anderson, CA, Ankeny, IA and
Ramoulaod, Que. We also intend to open other regional offices related to
development and supervision of the network as required on a short-term basis.

Legal Proceedings

     From time to time, we may be a party to various legal proceedings arising
in the ordinary course of our business.

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 Worldwide Fiber. See "Transactions with
Our Parent--Description of Reorganization and Related Agreements--Railplow."

                          TRANSACTIONS WITH OUR PARENT

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 certain other assets related
to the business of Ledcor's telecommunication division. As part of the
Reorganization, we also entered into the Construction Services Agreements to
complete the FOTS. Effective August 31, 1998, Ledcor transferred to us their 50%
interest in WFI-USA and, on December 31, 1998, we increased our interest in
WFI-USA to 75%.

     The material agreements we entered into with Ledcor in connection with the
Reorganization are described below.

     Railplow

     Effective May 31, 1998, the patent for the railplow which we use in
connection with the construction of our network was transferred to a subsidiary
of Ledcor ("Patent Co.") and we were concurrently granted a non-exclusive
license for its use. 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 Worldwide Fiber. 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; Employee Services Agreements

     We have entered into a Management Services Agreement and two Employee
Services Agreements with Ledcor. Under the Management Services Agreement, Ledcor
provides us with management staff and administrative and other support services.
We reimburse Ledcor for certain costs and pay a monthly fee of Cdn. $200,000
under the agreement. Under the Employee Services Agreements, Ledcor provides us
with personnel for the design, engineering, construction and installation of the
network and we reimburse Ledcor for the direct costs of these personnel. These
agreements are terminable at any time by either party. On January 1, 1999, the
personnel covered by the Employee Services Agreements, together with the
officers involved in our day-to-day management, became our employees.

     Construction Services Agreements

     We entered into 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 certain
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 certain
losses, liabilities, damages and claims that may arise under the agreement. In
return, Ledcor will pay us an amount equal to costs incurred plus 15% of our
total costs. Either party may terminate this agreement 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
Worldwide Fiber.



                                      -67-
<PAGE>

     Sale and Transfer Agreements

     We entered into a series of agreements that transferred equipment and other
assets of Ledcor's telecommunications division including a minimum of 12 strands
of dark fiber along the FOTS.

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

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

Acquisition of Fiber Optic Network Assets

     On September 27, 1999, we concluded a transaction with affiliates of Ledcor
whereby we acquired certain fiber optic network assets in consideration of the
issue of 4,500,000 of our Class C Multiple Voting shares. Each Class C Multiple
Voting share entitles the holder to 20 votes per share. In addition, we assumed
certain rights and obligations of the affiliates under their 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.

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. $700 million for the fiscal year ended August 31,
1998 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 (532 miles), MTS
Netcom Inc. (45 miles), AT&T (50 miles), AT&T Canada (227 miles), Alaska Fiber
Star (410 miles), Call-Net (200 miles), Bell Canada, AT&T Canada and Call-Net
(5,200 miles), Mi-Link Communications, LLC and Champlain Telephone (245 miles)
and World Net Communications Inc. (2,400 miles).

     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 Call-Net,
Sprint Canada and AT&T. After the successful completion of this project, Ledcor
began, as a developer, the FOTS, the first trans-Canadian fiber optic cable
network. To date, approximately 50% of the capacity on the FOTS available for
sale to third parties has been sold for an aggregate price of approximately Cdn.
$400 million to Bell Canada and AT&T Canada. Call-Net received a portion of
these proceeds as an owner of certain of these strands.



                                      -68-
<PAGE>

     The foundation of Ledcor's success and growth over the last 50 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.

                                   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 "Risks Factors--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 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 two 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 local exchange carriers,
including 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 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 Service--Universal Service." Private
carriers may also be subject to access charges if interconnected to local
exchange carriers.



                                      -70-
<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. In addition, certain 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 certain 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 nondominant common carrier. The FCC imposes regulations
on common carriers such as the RBOCs that have some degree of market power
("dominant carriers"). The FCC imposes less regulation on common carriers
without market power ("nondominant carriers"). Under the FCC's rules, we would
be a nondominant 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 ILECs and CLECs described in the next section. All telecommunications
carriers must also ensure that they do not install network features, functions
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.



                                      -71-
<PAGE>

     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 nondominant interstate
interexchange carriers 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 local exchange carriers. 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 certain 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 nondominant 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 nondominant interexchange carriers 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.

     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 certain
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.



                                      -72-
<PAGE>

     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 challenging 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 1999 because we had no significant end user revenues
in 1998. 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 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.



                                      -73-
<PAGE>

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.

     CLEC Offerings

     It is unclear whether we would be viewed as a local exchange carrier with
respect to the provision of some of our services. A local exchange carrier 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 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.



                                      -74-
<PAGE>

          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
     local exchange carrier 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-LATA services and for intra-LATA
     toll services. LECs are required to implement dialing parity for intra-LATA
     toll services during 1999.

          Access to Rights-of-Way. 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 certain 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 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.



                                      -75-
<PAGE>

     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 certain 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. To date, no RBOC has successfully
received FCC approval to provide inter-LATA telecommunication services. However,
certain 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 year. Bell Atlantic
in New York has filed for and may receive such approval by the end of 1999. In
anticipation of receiving inter-LATA approval, certain 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 recently
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. ss.ss. 34-39
("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



                                      -76-
<PAGE>

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:

     o    require the certification of telecommunications service providers,

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

     o    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.

     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. 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.



                                      -77-

Canada

     Companies that own or operate transmission facilities in Canada used to
offer telecommunications services to the public for compensation, are classified
as "telecommunications common carriers" ("TCCs") under Canada's
Telecommunications Act and, with the exception of telecommunications carriers in
the Province of Saskatchewan, are subject to the regulatory authority of the
Canadian Radio-television and Telecommunications Commission ("CRTC"), Canada's
federal telecommunications regulator. Unlike the dual jurisdictional arrangement
in the United States, there is no equivalent in Canada to U.S. state regulation
of telecommunications services. Consequently, both the local and long distance
operations of Canadian facilities-based telecommunications service providers are
subject to exclusive CRTC regulatory jurisdiction.

     Historically, the Canadian telecommunications industry has been
characterized by a number of regionally-based ILECs. These regional companies,
who later evolved into the Stentor alliance of telephone companies, were the
sole facilities-based providers of both local and long distance telephone
services in Canada. Each incumbent telephone company, with the exception of Bell
Canada, effectively operated in a province (with BC TEL serving most of British
Columbia, TELUS Communications Inc. ("Telus") serving Alberta, SaskTel serving
Saskatchewan, MTS Communications Inc. serving Manitoba, Bell Canada serving most
of Ontario and Quebec, Maritime Tel & Tel Limited serving Nova Scotia, The New
Brunswick Telephone Company, Limited serving New Brunswick, NewTel
Communications Inc. serving Newfoundland and The Island Telephone Company
Limited serving Prince Edward Island).

     In a series of decisions beginning in 1979, the CRTC has gradually opened
each telecommunications services market in Canada to competition, including the
private line voice and data markets in 1979, the enhanced and cellular services
markets in 1984, the domestic long distance voice market in 1992, the local
telephony market in 1997, and the international long distance and local pay
telephone markets in 1998.

     The CRTC has the power to forbear from regulating the services of Canadian
carriers where it finds that a telecommunications service or class of service is
or will be subject to competition sufficient to protect the interests of users.
Some Canadian carriers, such as the ILECs, are classified by the CRTC as
"dominant" because of their market power and control over the supply of local
services and certain long distance services. Carriers classified as
"non-dominant" by the CRTC are subject to less regulation than dominant carriers
and include facilities-based long distance providers such as AT&T Canada and
Call-Net Technology Services Inc. and CLECs, such as MetroNet Communications
Group Inc. (now AT&T Canada). The CRTC has forborne from regulating the long
distance services, private line services, dedicated access services and local
switched telephony services provided by carriers that are not affiliated with
the ILECs. In December 1997, the CRTC also forbore from regulating discount long
distance services and certain private line services offered by the ILECs finding
them to no longer possess significant market power in these market segments.

     We intend to retain fiber assets in our network which will be available for
sale, IRU or lease. To the extent that we engage in these activities,
particularly the provision of dark or lit fiber on a leased basis, we will be
subject to the provisions of the Telecommunications Act and to regulation by the
CRTC. However, in a 1995 decision, the CRTC concluded that telecommunications
services provided by non-dominant carriers should not be subject to extensive
regulation. We believe that all of the telecommunications services that we will
provide qualify under this decision as non-dominant carrier services. As such,
we do not believe that our operations in Canada will be subject to extensive
regulation by the CRTC. However, the CRTC's view as to the need for and extent
of regulation over non-dominant carriers may change.

     As a result of a September 17, 1998 application by four IXCs, 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



                                      -78-
<PAGE>

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 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. If the CRTC decides to adopt the approach advocated in the
application filed by the four IXCs, the current contribution regime would be
converted to a revenue-based regime under which contribution would be 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 our activities in Canada would be subject to the
requirement to pay contribution under the current contribution regime, except
with the possible exception of fiber which we may lease on a "lit" basis.
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.

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

     To the extent that we make available the retained fiber in our network in
Canada on an IRU or lease basis, we will be subject to the Canadian ownership
provisions of the Telecommunications Act. Although we believe that we are in
compliance with the relevant legislation, there can be no assurance that a
future CRTC determination or events beyond our control will not result in us
ceasing to comply with the ownership provisions of the Telecommunications Act.
Should this occur, our ability to operate as a Canadian carrier under the
Telecommunications Act could be jeopardized and our business could be materially
adversely affected.

     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 telecommunications common carrier. As a result, acquirors 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 telecommunications service providers 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 constructed by us, would be exempt
from the Canadian ownership provisions contained in the Telecommunications Act.

     In addition to determining the status of IRU 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,
telecommunications service providers and users in Canada may route basic
telecommunications traffic which either originates or



                                      -79-
<PAGE>

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 segments of the network in Canada may choose to purchase, lease or obtain
IRU 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 network, 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, indicate an intention on the part of Canadian ILECs to
compete in each other's traditional serving territories, which will create
increased opportunities for us in the Canadian carrier market.

                        DESCRIPTION OF WFI-USA AGREEMENTS

     On December 31, 1998, we increased our percentage shareholding in WFI-USA
from 50% to 75% under the terms of an agreement between, among others, Ledcor,
Michels, Mi-Tech, WFI-USA and us. To facilitate the purchase of the additional
25% interest, we funded the reimbursement by WFI-USA to Mi-Tech of a note for
shareholder advances in the aggregate amount of $10,188,230. A note for similar
advances by us in the amount of $3,915,000 was surrendered in exchange for the
issuance of additional shares of WFI-USA to us. We, Ledcor, Ledcor Industries
Inc., WFI-USA, WFNI, Mi-Tech and Michels entered into a shareholders agreement
(the "Shareholders Agreement") in which WFNI hired all Mi-Tech employees and
assumed all leases for facilities, office equipment and vehicles and other
obligations and liabilities of Mi-Tech, in each case located in Denver and
associated with the operations of WFNI. WFI-USA agreed to indemnify, release and
hold Mi-Tech harmless for any costs or liabilities related to these obligations
and agreements concerning these transactions.

     Commitments of Michels and Us

     Each of Michels and us have committed to support and assist WFI-USA in its
strategy to become a developer of fiber optic systems in the continental United
States. We will act as prime project construction manager for all projects of
WFI-USA, except to the extent that WFI-USA identifies an alternative source of
appropriate services local to the particular ROW to be developed for that
project. Any construction services provided by Michels or us to WFI-USA shall be
provided at a cost to WFI-USA equal to the actual cost of providing these
services plus 25%. Despite this commitment to support and assist, neither
Michels nor us will be required (1) to provide any services until WFI-USA has
used its best efforts to exhaust any and all other alternatives or (2) to
suspend or otherwise delay any work on any other project for any customer in
order to provide these services. Furthermore, Michels' and our respective
obligations to provide these services will be subject to the availability of
necessary personnel, equipment and supplies.

     Exclusivity; Non-Competition

     The parties to the Shareholders Agreement agreed that for a period of four
years, neither they nor their affiliates would compete directly with WFI-USA in
the continental United States, except for any segment which may be constructed
on ROW currently owned by CN or its subsidiaries, including IC.

     Transfer of Shares; Put Option of Mi-Tech

     The Shareholders Agreement restricts both Michels and us from selling,
transferring, assigning or otherwise encumbering or divesting any interest in or
control of WFI-USA to a third party. In addition, the Shareholders Agreement
provides for "tag-along" rights to Michels in the event of a sale by us of our
shares of WFI-USA. The Shareholders Agreement further provides that (1) in the
event of certain proposed transfers which would result in a change of control of
WFI-USA or (2) after the ten-year anniversary of the Shareholders Agreement,
Michels has the option to require WFI-USA to purchase all of the shares of
WFI-USA stock owned by Mi-Tech or its affiliates at the fair market value of the
shares. If Michels exercises the option described in (2) above, we can elect to
sell all of the shares or assets of WFI-USA whereupon WFI-USA will not be
required to purchase the shares. If we decide to sell WFI-USA in these
circumstances, the Shareholders Agreement contains certain provisions relating
to the price at which shares or assets of WFI-USA may be sold.

     Additional Fiber Options

     The Shareholders Agreement grants WFI-USA an option to purchase from
Mi-Tech 24 strands of dark fiber along the existing Montreal to Albany fiber
optic route owned by Mi-Tech and its affiliates. The Shareholders Agreement also
grants WFI-USA an option to purchase from us 24 strands of dark fiber along the
IC fiber optic build.



                                      -81-
<PAGE>

     Other Provisions

     If we commence a public offering of our common stock having an aggregate
value of at least $20 million, Mi-Tech has the option to convert all (but not
part) of its shares of WFI-USA stock into shares of our stock to be offered in
that public offering. The number of shares that Mi-Tech and its affiliates would
receive in a conversion would be the pre-offering fair market value of their
ownership interest in WFI-USA, divided by the offering price per share of stock
in that offering. The pre-offering fair market value would be determined by a
single appraiser selected by WFI-USA and Mi-Tech. If they could not agree on a
single appraiser, WFI-USA and Mi-Tech would each select an appraiser and the
pre-offering fair market value would be determined by averaging the fair market
values assigned by the two appraisers. In connection with this conversion,
Mi-Tech will be granted certain registration rights as provided in the
Shareholders Agreement.

     The Shareholders Agreement provides that the Board of Directors of WFI-USA
will initially consist of up to 10 directors, three of whom will be appointed by
Mi-Tech and the balance of whom will be appointed by us.

     Funding Commitments

     The Shareholders Agreement provides that we, or our affiliates will provide
the capital to fund WFI-USA's operations. Mi-Tech has retained an option to
contribute additional capital to WFI-USA to fund projects outside its scope of
business.

                       DESCRIPTION OF IC AND CN AGREEMENTS

     As of May 28, 1999, we formed, jointly with IC and CN, several subsidiaries
in which IC or CN own 25% equity interests. These subsidiaries are parties to
licenses of the ROW over which IC and CN operate their rail transportation
system.

     Scope and Duration of License

     Beginning May 28, 1999, IC and CN have granted some of our subsidiaries the
right to construct and operate fiber optic cable telecommunications facilities
upon almost all of the railroads' ROW. The licenses terminate on the first to
occur of May 28, 2059, the discontinuance by our subsidiaries of the use of the
facilities or upon the parties' mutual agreement.

     Exclusivity

     Generally, these licenses are exclusive, subject to (1) legal requirements,
(2) the rights of parties having existing telecommunications systems on the ROW
and (3) construction delays not having occurred. In addition, in some cases, and
subject to our right of first refusal, if either IC or CN receive an offer from
third parties to construct fiber optic telecommunications facilities on
specified portions of the ROW, that have not been previously designated as
portions on which we intend to construct, the railroads may grant a license to
such third parties.

     Consideration

     As consideration for the license, our subsidiaries have agreed to pay a
license fee for each facility equal to a per mile or per kilometer rate, as
applicable, multiplied by the length of the ROW upon which such facility is
constructed. This fee is payable from the cash flow relating to each such
facility, net of marketing, operations, maintenance, financing and other costs.
As additional consideration for the grant of the license, IC and CN were granted
equity in our subsidiaries and the subsidiaries have agreed to grant (for
railroad purposes only), (1) two strands of fiber optic cable along the entire
length of the facilities to major traffic centers to IC and (2) four strands of
fiber optic cable between Quebec City and Halifax to CN. At the request and
expense of the railroads, our subsidiaries will be required to light these
fibers.

     Security Interest

     In order to secure the license fee for each facility, our subsidiaries will
grant to IC or CN, as applicable, a first priority lien upon and security
interest in such facility and related property. No lien on any one facility will
secure the license fee owed on another facility. Furthermore, these liens are
subordinated to any security granted for project financing if (1) the aggregate
amount of the financing does not exceed 65% of the approved budgeted cost of
constructing the facility and (2) the project financing is provided on a
stand-alone basis, is not cross-collateralized and can not accelerate other
obligations of the subsidiary by cross-default.

     Sublicensing

     Our subsidiaries generally have the right to sublicense, and permit its
sublicensees to sublicense, all or portions of the facilities on the ROW to
third parties for a term of up to 40 years.

     Equity Interests

     IC and CN, as long as they own 10% of the respective subsidiaries described
above, have the right to appoint 25% of the members of each Board of the company
in which they hold their respective interest. Fur-



                                      -83-
<PAGE>

thermore, modifying the bylaws, settling litigation, granting of security
interests and entering into contracts not in the ordinary course for more than
$100,000 are examples of some activities which require unanimous consent of IC
or CN or their representatives. We have also agreed to provide financing for the
construction of fiber optic cable facilities along the ROW or guarantee, to the
extent necessary, any project financing with respect to such construction. These
agreements also include customary provisions regarding the termination and the
transfer of equity interests, as well as provisions which grant IC and CN the
right and obligation to exchange their interests for shares in WFI in the event
that we make an initial public offering of our common stock. The number of
shares that IC and CN would receive in a conversion would be the pre-offering
fair market value of their respective ownership interests in the subsidiaries
described above, divided by the offering price per share of stock in that
offering.

                      DESCRIPTION OF OUR RECENTLY COMPLETED
                            PRIVATE EQUITY PLACEMENTS

     On September 9, 1999, we completed a private placement of our convertible
preferred shares for $345 million to affiliates of Tyco International Ltd. and
to Providence Equity Partners Inc., DLJ Merchant Banking II Inc. and GS Capital
Partners III, LP (collectively, the "Private Investor Group"). We will use $300
million of the proceeds from the equity placements to provide funding for our
subsidiary which is undertaking our Hibernia project while the balance of $45
million was used to repurchase certain of our shares held by an affiliate of our
parent, Worldwide Fiber Holdings Ltd. Concurrent with the completion of the
equity placements, we also reorganized our share capital.

Share Capital Reorganization

     Our share capital now consists of four classes of shares: Class A
Non-Voting Shares; Class B Subordinate Voting Shares; Class C Multiple Voting
Shares and Preferred Shares. The Preferred Shares have been further divided into
three separate series of Preferred Shares: Series A Non-Voting Preferred Shares;
Series B Subordinate Voting Preferred Shares; and Series C Redeemable Preferred
Shares. Only the Class B Subordinate Voting Preferred Shares, Class C Multiple
Voting Shares and Series B Subordinate Voting Preferred Shares carry rights to
vote in all circumstances. In addition, while the Class B Subordinate Voting
Shares and Series B Subordinate Voting Preferred Shares carry one vote per
share, the Class C Multiple Voting Shares carry voting rights of 20 votes per
share. On September 27, 1999, 4.5 million of our Class C Multiple Voting Shares
were issued to affiliates of our parent in connection with our acquisition of
certain fiber optic network assets. See "Transactions with our Parent -
Acquisition of Fiber Optic Network Assets".

     The Private Investor Group purchased Series A Non-Voting Preferred Shares.
Our parent, through its affiliates, presently holds shares which provides it
with over 99% of the votes attached to our shares. However, the Private Investor
Group was provided with certain supermajority rights in the shareholders
agreement (the "Shareholders Agreement") entered into concurrently with the
closing of the private equity placements.

Attributes of the Series A Non-Voting Preferred Shares

     The attributes of the Series A Non-Voting Preferred Shares purchased by the
Private Investor Group, which are found in the share rights of our Articles of
Incorporation, include:

     o    The Series A Non-Voting Preferred Shares are convertible at the option
          of the holder into Class A Non-Voting Shares on a one-for-one basis
          provided that the conversion ratio will be adjusted upward by 6% per
          annum if, by September 9, 2000, we have not completed an initial
          public offering of $150 million at a price of at least 300% of the
          Private Investor Group purchase price (a "Qualified IPO").

     o    The Series A Non-Voting Preferred Shares are convertible at our option
          into Class A Non-Voting Shares at the same conversion ratio if a
          Qualified IPO has occurred and in certain other circumstances.

     o    The Series A Non-Voting Preferred Shares are also convertible on a
          one-for-one basis into Series B Subordinate Voting Preferred Shares
          which are, in turn, convertible into Class B Subordinate Voting Shares
          on the same terms upon which our Series A Non-Voting Preferred Shares
          are convertible into Class A Non-Voting Shares.

     o    The Series A Non-Voting Preferred Shares which have not previously
          been surrendered for conversion must be redeemed by us on November 2,
          2009. We must redeem the Series A Non-Voting Preferred Shares at their
          market price paid in (1) cash up to a set liquidation value and (2)
          Class A Non-Voting Shares for any excess of market price over
          liquidation value.



                                      -85-
<PAGE>

     o    The holders of our Preferred Shares have anti-dilution protection
          which is customary for convertible securities.

     o    The holders of our Preferred Shares receive a preference over other
          classes of shares upon our liquidation, dissolution or winding-up.

     The ability of the Private Investor Group to convert their Preferred Shares
into our shares which vote in all circumstances is also limited by the
provisions of the Shareholders Agreement as well as the "constrained share
provisions" contained in our share rights which are designed to ensure that we
will continue to comply with the foreign ownership restrictions under the
Telecommunications Act (Canada). In addition, under the terms of the Purchase
Agreement for the Series A Non-Voting Preferred Shares, additional anti-dilution
protection was provided to the Private Investor Group which is triggered upon
the issue of options to purchase our shares as well as upon the issue of our
shares to Michels, CN or IC in exchange for the transfer of their interest in
our subsidiaries. The Series A Non-Voting Preferred Shares represent a minority
of our shares on a fully-diluted basis.

Shareholders Agreement

     In connection with the private placement to the Private Investor Group, we
entered into a Shareholders Agreement with the Private Investor Group, our
parent and its affiliate and our directors. The Shareholders Agreement generally
provides for:

     o    prescribed board of directors composition.

     o    "supermajority" rights with respect to prescribed matters.

     o    restrictions on the issue and conversion of our shares.

     o    other matters including restrictions on transferability.

Board of Directors Composition

     Under the Shareholders Agreement, each of the four members of the Private
Investor Group is entitled to name one person to our Board of Directors and our
Board must consist of not more than 12 directors.

Supermajority Rights of the Private Investor Group

     Until we complete an initial public offering of at least $150 million, we
must not undertake certain major transactions if three of the four members of
the Private Investor Group provide us with a notice of their election to
disapprove of that major transaction. Major transactions subject to the
supermajority rights include: mergers or other similar business combinations;
acquisitions or investments having a value greater than $200 million, a
significant change in the nature of our business; a sale of our assets outside
the ordinary course of business with a value of $100 million or more;
declaration of dividends or redemption or repurchase of shares; issuing shares
with an aggregate value of greater than $100 million; certain non-arm's length
transactions; amending our corporate charter; incurring indebtedness of $100
million or more; approval of our annual financing and capital plans; issuing our
shares below a threshold price; and terminating our senior officers.

Obligations Relating to Share Issuances and Conversion

     Under the Shareholder's Agreement, there are a number of provisions which
impact our ability to issue shares. We cannot issue shares on a private basis to
a person who would then own more than 1% of our shares



                                      -86-
<PAGE>

without that person agreeing to be bound by the Shareholders Agreement. Except
for certain "grandfathered" share issuances, until the holders of the Series A
Non-Voting Preferred Shares convert their shares to a non-Preferred share class,
our share issuances are subject to pre-emptive rights in favour of the holders
of the Preferred Shares. In addition, until the Telecommunications Act (Canada)
foreign ownership restrictions are amended, we may not issue any shares which
carry a right to vote in all circumstances except for certain grandfathered
share issuances. However, the holders of the Series A Non-Voting Preferred
Shares cannot convert into our shares which carry a right to vote in all
circumstances unless the foreign ownership restrictions in the
Telecommunications Act (Canada) are eliminated or concurrently with or after an
initial public offering of shares with voting rights of at least $150 million.

Additional Provisions

     The Shareholders Agreement contains a number of provisions which limit the
transfer of our shares by all shareholders. These include an absolute
prohibition, subject to certain exceptions, on the transfer of shares during a
one year lock-up period, rights of first offer, tag along rights and bring along
rights. Finally, if we have not completed a Qualified IPO by September 9, 2003,
certain of the Private Investor Group may demand an auction of the Company.

                               THE EXCHANGE OFFER

Purpose and Effect of Exchange Offer

     We sold the old notes on July 28, 1999 to the initial purchasers, who
placed the old notes with certain institutional investors. We and the initial
purchasers entered into the registration rights agreement, concerning the
placement of the old notes, under which we agreed, for the benefit of the
holders of the old notes, that we would, at our sole cost, (1) within 90 days
following the original issuance of the old notes, file with the Securities and
Exchange Commission the exchange offer registration statement under the
Securities Act concerning an issue of a series of new notes of Worldwide Fiber
identical in all material respects to the series of old notes and (2) use our
best efforts to cause the exchange offer registration statement to become
effective under the Securities Act within 180 days following the original
issuance of the old notes. Upon the effectiveness of the exchange offer
registration statement, we will offer to the holders of the old notes the
opportunity to exchange their old notes for an equal amount of new notes, to be
issued without a restrictive legend and which may be reoffered and resold by the
holder without restrictions or limitations under the Securities Act. The term
"holder" concerning any note means any person in whose name the note is
registered on our books or any other person who has obtained a properly
completed bond power from the registered holder.

Terms of the Exchange Offer

     Upon the terms and subject to the conditions described in this prospectus
and in the accompanying letter of transmittal (which together constitute the
exchange offer), we will accept for exchange old notes that are properly
tendered on or before the expiration date and not withdrawn as permitted below.
The term expiration date means 5:00 p.m., New York City time, on , 1999; but if
we, in our sole discretion, extend the period of time during which the exchange
offer is open, the term expiration date means the latest time and date to which
the exchange offer is extended. We may choose to extend the period of time
during which the exchange offer is open if we do not receive substantially all
of the old notes in the exchange offer.

     As of the date of this prospectus, $500,000,000 aggregate principal amount
of old notes is outstanding. This prospectus, along with the letter of
transmittal, is first being sent on or about , 1999, to all holders of old notes
known to us. Our obligation to accept old notes for exchange under the exchange
offer is subject to certain customary conditions as described below under
"--Certain Conditions to the Exchange Offer."

     We expressly reserve the right, at any time and from time to time, to
extend the period of time during which the exchange offer is open, and
therefore, to delay acceptance for exchange of any old notes, by giving oral or
written notice of an extension to the holders of the old notes as described
below. During the extension, all old notes previously tendered will remain
subject to the exchange offer and may be accepted for exchange by us. Any old
notes not accepted for exchange for any reason will be returned without expense
to the tendering holders of old notes as promptly as practicable after the
expiration or termination of the exchange offer.



                                      -88-
<PAGE>

     Old notes tendered in the exchange offer must be in denominations of $1,000
or any integral multiple of $1,000.

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

Procedures for Tendering Old Notes

     If you are a registered holder of old notes you may tender your old notes
in the exchange offer. If you tender old notes to Worldwide Fiber as described
below, our acceptance of your old notes will constitute a binding agreement
between you and Worldwide Fiber upon the terms and subject to the conditions
described in this prospectus and in the accompanying letter of transmittal.
Except as described below, if you wish to tender old notes for exchange through
the exchange offer, you must transmit either (1) a properly completed and duly
executed letter of transmittal, including all other documents required by the
letter of transmittal, to HSBC Bank USA, the exchange agent, at one of the
addresses listed below under "Exchange Agent" on or before the expiration date
or (2) if you tender your old notes under the procedures for book-entry transfer
described below, you may transmit an agent's message to the exchange agent
instead of the letter of transmittal, in either case on or prior to the
expiration date. In addition, either

     o    certificates for the old notes must be received by the exchange agent
          along with the letter of transmittal, or

     o    a timely confirmation of a book-entry transfer (a "Book-Entry
          Confirmation") of the old notes, if this procedure is available, into
          the exchange agent's account at the Depository Trust Company (the
          "Book-Entry Transfer Facility") under the procedure for book-entry
          transfer described below, along with the letter of transmittal or
          agent's message, must be received by the exchange agent before the
          expiration date, or

     o    the holder must comply with the guaranteed delivery procedures
          described below.

     The term "agent's message" means a message, transmitted to the Exchange
Agent, which states that the Book-Entry Transfer Facility has received an
express acknowledgment from you that you have received and agree to be bound by
the letter of transmittal and that Worldwide Fiber may enforce the letter of
transmittal against you.

     The method of delivery of old notes, letters of transmittal or the agent's
message and all other required documents is at your election and risk. If you
mail these documents, we recommend that you use registered mail, properly
insured, with return receipt requested. Always allow sufficient time to assure
timely delivery. Do not send letters of transmittal or old notes to the company.
You may request your respective brokers, dealers, commercial banks, trust
companies or nominees to effect the above transactions for you.

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

     Signatures on a letter of transmittal or a notice of withdrawal described
below (see "--Withdrawal of Tenders") must be guaranteed (see "--Guaranteed
Delivery Procedures") unless the old notes surrendered for exchange are tendered
(1) by a registered holder of the old notes who has not completed the box
entitled "Special Issuance Instructions" or "Special Delivery Instructions" on
the letter of transmittal or (2) for the account of an Eligible Institution (as
defined below). If signatures on a letter of transmittal or a notice of
withdrawal are required to be guaranteed, these guarantees must be by a
financial institution (including most banks, savings and loan associations and
brokerage houses) that is a participant in the Securities Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Program or the Stock
Exchange Medallion Program



                                      -89-
<PAGE>

(collectively, "Eligible Institutions"). If old notes are registered in the name
of a person other than a signer of the letter of transmittal, the old notes
surrendered for exchange must be endorsed by or be accompanied by a written
instrument or instruments of transfer or exchange in satisfactory form as
determined by us in our sole discretion, duly executed by the registered holder
exactly as the name or names of the registered holder or holders appear on the
old notes with the signature on it guaranteed by an Eligible Institution.

     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of old notes tendered for exchange will be determined by
us in our discretion, which determination shall be final and binding. We reserve
the absolute right to reject any and all tenders of any particular old notes not
properly tendered or the acceptance of which might, in our judgment or in the
judgment of our counsel, be unlawful. We also reserve the absolute right to
waive any defects or irregularities or conditions of the exchange offer as to
any particular old notes either before or after the expiration date (including
the right to waiver the ineligibility of any holder who seeks to tender old
notes in the exchange offer). Our interpretation of the terms and conditions of
the exchange offer as to any particular old notes either before or after the
expiration date (including the letter of transmittal and its instructions) shall
be final and binding on all parties. Unless waivered, any defects or
irregularities in connection with tenders of old notes for exchange must be
cured within a reasonable period of time as we shall determine. None of
Worldwide Fiber, the exchange agent or any other person shall be under any duty
to notify of any defect or irregularity of any tender of old notes for exchange,
nor shall any of them have any liability for failure to notify.

     By tendering old notes for exchange, you represent to us that, among other
things:

     o    the new notes acquired through the exchange offer are being acquired
          in the ordinary course of business of the person receiving the new
          notes, whether or not this person is the holder, and

     o    that neither the holder nor the other person has any arrangement or
          understanding with any person to engage or participate in a
          distribution of the new notes.

     If any holder or an other person is an affiliate, as defined under Rule 405
of the Securities Act, of us or is engaged in or intends to engage in, or has an
arrangement or understanding with any person to participate in, a distribution
of the new notes to be acquired through the exchange offer, the holder or the
other person (1) may not rely on the applicable interpretation of the staff of
the Securities and Exchange Commission and (2) must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any resale transaction. Each broker-dealer that receives new notes for its own
account in exchange for old notes, where the old notes were acquired by the
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of the new notes. See "Plan of Distribution." The letter of
transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not have admitted that it is an "underwriter" within the
meaning of the Securities Act.

Acceptance of Old Notes for Exchange; Delivery of New Notes

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

     For each old note accepted for exchange you will receive a new note having
a principal amount equal to that of the surrendered old note. Accordingly,
registered holders of new notes on the relevant record date for the first
interest payment date following the consummation of the exchange offer will
receive interest accruing from the most recent date of which interest has been
paid on the old notes or, if no interest has been paid, from



                                      -90-
<PAGE>

July 28, 1999. Old notes accepted for exchange will cease to accrue interest
from and after the date of consummation of the exchange offer. Holders whose old
notes are accepted for exchange will not receive any payment of accrued interest
on these old notes otherwise payable on any interest payment date for which the
record date occurs on or after the completion of the exchange offer. Old notes
not tendered or not accepted for exchange will continue to accrue interest from
and after the date of the completion of the exchange offer.

     In all cases, issuance of new notes for old notes that are accepted for
exchange through the exchange offer will be made only after timely receipt by
the exchange agent of certificates for these old notes or a timely Book-Entry
Confirmation of these old notes into the exchange agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed letter of
transmittal and all other required documents or, in the case of a Book-Entry
Confirmation, an agent's message. If any tendered old notes are not accepted for
any reason under the terms and conditions of the exchange offer or if old notes
are submitted for a greater amount than the holder desires to exchange, those
unaccepted or non-exchanged old notes will be returned without expense to the
tendering holder of the notes or, in the case of old notes tendered by
book-entry transfer into the exchange agent's account at the Book-Entry Transfer
Facility according to the book-entry procedures described below, and any
financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of old notes by causing the
Book-Entry Transfer Facility under the Book-Entry Transfer Facility's procedures
for transfer. However, although delivery of old notes may be effected through
book-entry transfer at the Book-Entry Transfer Facility, the letter of
transmittal or facsimile of it, with any required signature guarantees or an
agent's message instead of a letter of transmittal, and any other required
documents, must be transmitted to and received by exchange agent at the
addresses described below under "--Exchange Agent" on or before the expiration
date or the guaranteed delivery procedures described below must be complied
with.

Guaranteed Delivery Procedures

     If a registered holder of the old notes desires to tender their old notes
and the old notes are not immediately available, or time will not permit the
holder's old notes or other required documents to reach the exchange agent
before the expiration date, or the procedures for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if:

     o    the tender is made through an Eligible Institution,

     o    on or before 5:00 P.M., New York City time, on the expiration date,
          the exchange agent receives from the Eligible Institution a properly
          completed and duly executed letter of transmittal or a facsimile of
          it, and Notice of Guaranteed Delivery, substantially in the form
          provided by us, by telegram, telex, facsimile transmission, mail or
          hand delivery, setting forth the name and address of the holder of the
          old notes and the amount of old notes tendered, stating that the
          tender is being made by the delivery of the letter of transmittal and
          guaranteeing that within three New York Stock Exchange trading days
          after the date of execution of the Notice of Guaranteed Delivery, the
          certificates for all physically tendered old notes, in proper form for
          transfer, or a Book-Entry Confirmation and any other documents
          required by the letter of transmittal will be deposited by the
          Eligible Institution with the exchange agent, and

     o    the certificates for all physically tendered old notes, in paper form
          for transfer, or a Book-Entry Confirmation, and any other documents
          required by the letter of transmittal will be deposited by the
          Eligible Institution within three New York Stock Exchange trading days
          after the date of execution of the Notice of Guaranteed Delivery.



                                      -91-
<PAGE>

Withdrawal of Tenders

     Tenders of old notes may be withdrawn at any time before 5:00 P.M., New
York City time, on the expiration date. For a withdrawal to be effective, a
written notice of withdrawal must be received by the exchange agent at one of
the addresses described below under "--Exchange Agent." This notice of
withdrawal must specify the name of the person having tendered the old notes to
be withdrawn, identify the old notes to be withdrawn, including the principal
amount of the old notes, and, where certificates for old notes have been
transmitted, specify the name in which the old notes are registered, if
different from that of the withdrawing holder. If certificates for old notes
have been delivered or otherwise identified to the exchange agent, then before
the release of these certificates the withdrawing holder must also submit the
serial numbers of the particular certificates to be withdrawn and a signed
notice of withdrawal with signatures guaranteed by an Eligible Institution
unless the holder is an Eligible Institution in which case the guarantee will
not be required. If old notes have been tendered under the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn old notes and otherwise comply with the procedures
of the facility. We will determine all questions concerning the validity, form
and eligibility, including time of receipt, of the notices. This determination
will be final and binding on all parties. Any old notes so withdrawn will be
considered not to have been validly tendered for exchange and will be returned
to the holder of the old notes without cost to the holder, or, in the case of
old notes tendered by book-entry transfer into the exchange agent's account at
the Book-Entry Transfer Facility maintained with the Book-Entry Transfer
Facility for the old notes, as soon as practicable after withdrawal, rejection
of tender or termination of the exchange offer. Properly withdrawn old notes may
be retendered by following one of the procedures described under "--Procedures
for Tendering Old Notes" above at any time on or before the expiration date.

Material Conditions to the Exchange Offer

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

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

          (b) any change, or any development involving a prospective change, in
     our business or financial affairs or any or our subsidiaries has occurred
     which, in our sole judgment, might materially impair our ability to proceed
     with the exchange offer or materially impair the contemplated benefits of
     the exchange offer to us;

          (c) any law, statute, rule or regulation is proposed, adopted or
     enacted, which, in our sole judgment, might materially impair our ability
     to proceed with the exchange offer or materially impair the contemplated
     benefits of the exchange offer to us;

          (d) any governmental approval has not been obtained, which approval we
     shall, in our sole discretion, consider necessary for the completion of the
     exchange offer; or

          (e) the exchange offer will violate any applicable law or any
     applicable interpretation of the staff of the Securities and Exchange
     Commission.



                                      -92-
<PAGE>

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

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

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

Resales of the New Notes

     Based on positions of the Securities and Exchange Commission described in
Morgan Stanley & Co. Incorporated (available June 5, 1991) and Exxon Capital
Holdings Corporation (available July 2, 1993) and K-III Communications
Corporation (available May 14, 1993), and similar no-action letters issued to
third parties, we believe that the new notes issued in the exchange offer to a
holder in exchange for old notes may be offered for resale, resold and otherwise
transferred by any holder of old notes, except for a holder which is an
affiliate of Worldwide Fiber within the meaning of Rule 405 under the Securities
Act, without compliance with the registration and prospectus delivery provisions
of the Securities Act, if the new notes are acquired in the ordinary



                                      -93-
<PAGE>

course of the holder's business and the holder is not participating, does not
intend to participate and has no arrangement or understanding with any person to
participate in the distribution of the new notes. We have not requested or
obtained, and do not intend to seek, an interpretive letter from the staff of
the Securities and Exchange Commission concerning this exchange offer, and
neither we nor the holders of notes are entitled to rely on interpretive advice
provided by the staff of the Securities and Exchange Commission to other
persons, which advice was based on the facts and conditions represented in the
letters. Although there can be no assurance that the staff of the Securities and
Exchange Commission would make a similar determination relating to the exchange
offer, the exchange offer is being conducted in a manner intended to be
consistent with the facts and conditions represented in these letters. If any
holder acquires new notes in the exchange offer to distribute or participate in
a distribution of the new notes, the holder cannot rely on the position of the
staff of the Securities and Exchange Commission described in the above no-action
and interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act concerning a secondary resale
transaction, unless an exemption from registration is otherwise available.

     Each broker-dealer that receives new notes for its own account through the
exchange offer must acknowledge that it will deliver a prospectus concerning any
resale of these new notes. This prospectus, as it may be amended or supplemented
from time to time, may be used by a broker-dealer concerning resales of new
notes received in exchange for old notes where the old notes were acquired by
the broker-dealer as a result of market-making activities or other trading
activities, except for old notes acquired directly from us. We have agreed that,
for a period of 180 days following the completion of the exchange offer, we will
make this prospectus available to any broker-dealer for use with any of these
resales. See "Plan of Distribution." Under the registration rights agreement, we
are required to allow the broker-dealers and other persons, if any, subject to
similar prospectus delivery requirements to use this prospectus concerning the
resale of the new notes.

Fees and Expenses

     We will pay the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, additional solicitation may be made by
telegraph, telephone or in person by our officers and regular employees and our
affiliates.

     We have not retained any dealer-manager relating to the exchange offer and
will not make any payments to brokers, dealers or others soliciting acceptances
of the exchange offer. However, we will pay the exchange agent reasonable and
customary fees for its services and will reimburse it for its reasonable
out-of-pocket expenses relating to these services.

     We will pay the cash expense incurred for the exchange offer. These
expenses include fees and expenses of the exchange agent and trustee, accounting
and legal fees and printing costs, among others.

     We will pay all transfer taxes, if any, applicable to the exchange of old
notes through the exchange offer. If, however, certificates representing new
notes or old notes for principal amounts not tendered or accepted for exchange
are to be delivered to, or are to be issued in the name of, any person other
than the registered holder of the old notes tendered, or if tendered old notes
are registered in the name of any person other than the person signing the
letter of transmittal, or if a transfer tax is imposed for any reason other than
the exchange of old notes under the exchange offer, then the amount of these
transfer taxes, whether imposed on the registered holder or any other person,
will be payable by the tendering holder. If satisfactory, evidence of payment of
these taxes or exemption from payment of these taxes is not submitted with the
letter of transmittal, the amount of the transfer taxes must accompany the
tender of old notes.



                                      -94-
<PAGE>

Accounting Treatment

     The new notes will be recorded at the same carrying value as the old notes,
which is the principal amount as reflected in our accounting records on the date
of the exchange. Accordingly, we will recognize no gain or loss for accounting
purposes. The expenses of the exchange offer and the unamortized expenses
related to the issuance of the old notes will be amortized over the term of the
new notes.

Regulatory Approvals

     We do not believe that we need to obtain any material federal or state
regulatory approvals concerning the exchange offer.

Transfer Taxes

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

Other

     Participation in the exchange offer is voluntary and you should carefully
consider whether to accept the terms and conditions of the exchange offer. You
are urged to consult your financial and tax advisors in making your decisions on
what action to take concerning to the exchange offer.

     As a result of the making of, and upon acceptance for exchange of all
validly tendered old notes under the terms of the exchange offer, we will have
fulfilled a covenant contained in the terms of the old notes and the
registration rights agreement. If you do not tender your old notes in the
exchange offer you will continue to hold these old notes and will be entitled to
all the rights, and limitations applicable to it, under the indenture, except
for the rights under the registration rights agreement, including rights to
receive Additional Interest, which by their terms terminate or cease to have
further effect as a result of the making and completion of the exchange offer.
All untendered old notes will continue to be subject to the restrictions on
transfer contained in the indenture and we do not currently anticipate that we
will register the old notes under the Securities Act. If old notes are tendered
and accepted in the exchange offer, the trading market, if any, for any
remaining old notes could be adversely affected. See "Risk Factors--Failure to
Exchange or Comply with the Exchange Offer--This will result in continuing
transfer restrictions or result in the inability to exchange."

                              DESCRIPTION OF NOTES

     You can find the definitions of certain terms used in this description
under the subheading "Certain Definitions." In this description the words "we",
"us", "ours" and "Worldwide Fiber" refer only to Worldwide Fiber Inc. and not to
any of its subsidiaries.

     The old notes were, and the new notes will be, issued under an indenture
between Worldwide Fiber and HSBC Bank USA, as trustee. The terms of the new
notes are identical in all material respects to the old notes, except that the
new notes have been registered under the Securities Act and, therefore, will not
bear legends restricting their transfer and will not contain certain provisions
providing for an increase in interest on them under certain circumstances
described in the registration rights agreement, the provisions of which will
terminate upon the completion of the exchange offer. The terms of the Notes
include those stated in the indenture and those made part of the indenture by
reference to the Trust Indenture Act of 1939 or the TIA.

     The following description is a summary of the material provisions of the
indenture. It does not restate that agreement in its entirety. We urge you to
read the indenture and registration rights agreement because they, and not this
description, define your rights as holders of the notes. Copies of the indenture
and registration rights agreement are available as described below under
"Additional Information."

Brief Description of the Notes

     The notes:

     o    are our general unsecured obligations;

     o    are effectively subordinated in right of payment to all our existing
          and future secured Indebtedness to the extent of the value of the
          assets securing such Indebtedness and to all liabilities, including
          trade payables, of our subsidiaries;

     o    are equal in right of payment to all our existing and future
          unsubordinated, unsecured Indebtedness; and

     o    will be senior in right of payment to any of our future subordinated
          Indebtedness.

     The indenture will permit us to assume additional Indebtedness, including
secured Indebtedness.

     We conduct substantially all of our operations through our subsidiaries. As
a result, we depend upon the cash flow of our subsidiaries to meet our
obligations, including our obligations under the notes. As of the Issue Date,
all of our subsidiaries will be "Restricted Subsidiaries." However, under the
circumstances described below under the caption "Certain Covenants--Designation
of Restricted and Unrestricted Subsidiaries," we will be permitted to designate
certain of our subsidiaries as "Unrestricted Subsidiaries." Unrestricted
Subsidiaries will not be subject to many of the restrictive covenants in the
indenture. None of our subsidiaries will guarantee the notes.

Principal, Maturity and Interest

     We issued old notes with a principal amount of $500.0 million. The notes
are and will be in denominations of $1,000 and integral multiples of $1,000. The
notes will mature on August 1, 2009. Additional Senior Notes (as defined below)
may be issued from time to time, subject to the limitations described under
"Certain Incurrence of Indebtedness and Issuance of Preferred Stock."



                                      -96-
<PAGE>

     Interest on the notes will accrue at the rate of 12% per year and will be
payable semiannually in arrears on February 1 and August 1, beginning on
February 1, 2000. We will make each interest payment to the holders of record of
notes on the immediately preceding January 15 and July 15.

     Interest on the notes will accrue from the date the notes were originally
issued, if interest has already been paid, from the date it was most recently
paid. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months.

Methods of Receiving Payments on the Notes

     If a holder has given wire transfer instructions to us, we will make all
principal, premium, if any, and interest payments on those notes in accordance
with those instructions. All other payments on the notes will be made at the
office or agency of the Paying Agent and Registrar within the City and State of
New York unless we elect to make interest payments by check mailed to the
holders at their address described in the register of holders.

Paying Agent and Registrar for the Notes

     The trustee will initially act as Paying Agent and Registrar. We may change
the Paying Agent or Registrar without prior notice to the holders of the notes,
and we or any of our Subsidiaries may act as Paying Agent or Registrar.

Transfer and Exchange

     A holder may transfer or exchange notes in accordance with the indenture.
The Registrar and the trustee may require a holder, among other things, to
furnish appropriate endorsements and transfer documents and we may require a
holder to pay any transfer taxes and similar fees required by law or permitted
by the indenture. We are not required to transfer or exchange any note selected
for redemption. Also, we are not required to transfer or exchange any note for a
period of 15 days before a selection of notes to be redeemed.

     The registered holder of a note will be treated as the owner of it for all
purposes, other than concerning the payment of Additional Amounts (as defined
below).

Optional Redemption

     Before August 1, 2002, we may on any one or more occasions redeem notes in
an amount equal up to 35% of the sum of (a) the aggregate principal amount of
notes originally issued under the indenture and (b) the total amount of
Additional Senior Notes issued under the indenture at a redemption price of 112%
of the principal amount thereof, plus accrued and unpaid interest, if any,
thereon to the redemption date, with the net cash proceeds of one or more
Qualified Equity Offerings; provided that:

(1)  at least 65% of the sum of (a) the aggregate principal amount of notes
     originally issued under the indenture and (b) the total amount of
     Additional Senior Notes issued under the indenture remains outstanding
     immediately after the occurrence of the redemption, excluding notes held by
     Worldwide Fiber and our Subsidiaries; and

(2)  the redemption must occur within 90 days of the date of the closing of the
     Qualified Equity Offering.

     Except according to the preceding paragraph or as described below under the
caption "Redemption for Changes in Canadian Withholding Taxes," the notes will
not be redeemable at our option before August 1, 2004.



                                      -97-
<PAGE>

     On or after August 1, 2004 we may redeem all or a part of the notes upon
not less than 30 nor more than 60 days' notice, at the redemption prices,
expressed as percentages of the principal amount, described below plus accrued
and unpaid interest, if any, on the notes to the applicable redemption date, if
redeemed during the twelve-month period beginning on August 1 of the years
indicated below:

   Date                                             Percentage
   ----                                             ----------

   2004..........................................      106.000%
   2005..........................................      104.000%
   2006..........................................      102.000%
   2007 and thereafter...........................      100.000%

Redemption for Changes in Canadian Withholding Taxes

     The notes will be subject to redemption, at our option, in the event we
become obligated to pay any Additional Amounts as a result of a change in the
laws or regulations of Canada or any Canadian Taxing Authority, or a change in
any official position regarding the application or interpretation of those laws
and regulations, which is publicly announced or becomes effective on or after
the Issue Date. Upon the occurrence of this kind of change, Worldwide Fiber may,
at any time, redeem all, but not part, of the notes at a price equal to 100% of
the principal amount of the notes, plus accrued and unpaid interest, if any, to
the redemption date. Worldwide Fiber will give written notice of the redemption
not less than 30 nor more than 60 days before the redemption date.

Payment of Additional Amounts

     All payments made by or on behalf of Worldwide Fiber on or with respect to
the notes will be made without withholding or deduction for any Taxes imposed by
any Canadian Taxing Authority, unless required by law or the interpretation or
administration of withholding or deduction of Taxes by the relevant Taxing
Authority. If Worldwide Fiber or any other payor is required to withhold or
deduct any amount on account of Taxes from any payment made with respect to the
notes, Worldwide Fiber will:

(1)  make the withholding or deduction;

(2)  remit the full amount deducted or withheld to the relevant government
     authority in accordance with applicable law;

(3)  pay such additional amounts ("Additional Amounts") as may be necessary so
     that the net amount received by each holder, including Additional Amounts,
     after the withholding or deduction will not be less than the amount the
     holder would have received if the Taxes had not been withheld or deducted;

(4)  furnish to the holders, within 30 days after the date the payment of any
     Taxes is due, certified copies of tax receipts evidencing the payment by
     Worldwide Fiber;

(5)  indemnify and hold harmless each holder, other than an Excluded Holder, for
     the amount of (a) any Taxes paid by the holder as a result of payments made
     on or with respect to the notes, (b) any liability, including penalties,
     interest and expenses, arising from the notes or with respect to the notes
     and (c) any Taxes imposed with respect to any reimbursement under (a) or
     (b), but excluding the Taxes on the holder's net income; and



                                      -98-
<PAGE>

(6)  at least 30 days before each date on which any Additional Amounts are
     payable, deliver to the trustee an Officers' Certificate stating the
     amounts so payable and any other information necessary to enable the
     trustee to pay the Additional Amounts to holders on the payment date.

     Despite the above, no Additional Amounts will be payable to a holder for a
beneficial owner of a note (an "Excluded Holder"):

(1)  with which Worldwide Fiber does not deal at arm's length (within the
     meaning of the Income Tax Act (Canada)) at the time of making the payment;
     or

(2)  which is subject to the Taxes because of its being connected with Canada or
     any province or territory of Canada otherwise than by the mere acquisition,
     holding or disposition of notes or the receipt of payments under the notes.

     Whenever there is a reference in the indenture to, in any context, the
payment of principal, premium, if any, redemption price, Change of Control
Payment, offer price and interest, or any other amount payable under or
concerning any note, this reference shall be considered to include a reference
of the payment of Additional Amounts to the extent that, in this context,
Additional Amounts are, were or would be payable on the note. Our obligation to
make payments of Additional Amounts shall survive any termination of the
indenture or the defeasance of any rights under the notes. For a discussion of
the exemption from Canadian withholding taxes applicable to payments under or
concerning the notes, see "Material United States and Canadian Income Tax
Considerations--Canada."

Mandatory Redemption

     Except as described below under "--Repurchase at the Option of Holders,"
Worldwide Fiber is not required to make mandatory redemption or sinking fund
payments concerning the notes.

Repurchase at the Option of Holders

     Change of Control

     If a Change of Control occurs, each holder of notes will have the right to
require Worldwide Fiber to repurchase all or any part, equal to $1,000 or an
integral multiple of $1,000, of that holder's notes through the Change of
Control Offer. In the Change of Control Offer, Worldwide Fiber will offer a
Change of Control Payment in cash equal to 101% of the aggregate principal
amount of notes repurchased plus accrued and unpaid interest, if any, on the
notes to the date of purchase. Within 30 days following any Change of Control,
Worldwide Fiber will mail a notice to each holder, with a copy to the trustee,
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase notes on the Change of Control Payment Date specified
in the notice, under the procedures required by the indenture and described in
the notice. Worldwide Fiber will comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations under the
Exchange Act to the extent these laws and regulations are applicable to the
repurchase of the notes as a result of a Change of Control.

     On the Change of Control Payment Date, Worldwide Fiber will, to the extent
lawful:

     (1)  accept for payment all notes or portions of the notes properly
          tendered under the Change of Control Offer;

     (2)  deposit with the Paying Agent an amount equal to the Change of Control
          Payment plus accrued and unpaid interest, if any, on the notes for all
          notes or portions of notes so tendered; and



                                      -99-
<PAGE>

     (3)  deliver or cause to be delivered to the trustee the notes so accepted
          together with an Officers' Certificate stating the aggregate principal
          amount of notes or portions of the notes being purchased by Worldwide
          Fiber.

     The Paying Agent will promptly mail to each holder of notes so tendered the
Change of Control Payment plus accrued and unpaid interest, if any, on the notes
for these notes, and the trustee will promptly authenticate and mail, or cause
to be transferred by book entry, to each holder a new note equal in principal
amount to any unpurchased portion of the notes surrendered, if any; provided
that each new note will be in a principal amount of $1,000 or an integral
multiple of $1,000. Worldwide Fiber will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.

     The provisions described above that require Worldwide Fiber to make a
Change of Control Offer following a Change of Control will be applicable whether
or not any other provisions of the indenture are applicable. Except as described
above concerning a Change of Control, the indenture does not contain provisions
that permit the holders of the notes to require that Worldwide Fiber repurchase
or redeem the notes in the event of a takeover, recapitalization or similar
transaction.

     Worldwide Fiber's ability to purchase notes through a Change of Control
Offer may be limited by a number of factors. If Worldwide Fiber enters into one
or more Credit Facilities, as currently anticipated, the Credit Facility is
expected to prohibit Worldwide Fiber from purchasing any notes and is expected
to provide that certain change of control events concerning Worldwide Fiber
would constitute a default under the notes. In the event a Change of Control
occurs at a time when Worldwide Fiber is prohibited from purchasing notes,
Worldwide Fiber could seek consent to the purchase of notes or could attempt to
refinance the borrowings that contain this prohibition. If Worldwide Fiber does
not obtain this consent or repay the borrowings, Worldwide Fiber will remain
prohibited from purchasing notes. In this case, Worldwide Fiber's failure to
purchase tendered notes would constitute an Event of Default under the indenture
which likely would, in turn, constitute a default under the Credit Facility and
under the terms of the 1998 Notes. In these circumstances, any security granted
for the Credit Facility could result in the holders of notes receiving less
ratably than the lenders under the Credit Facility.

     Worldwide Fiber will not be required to make a Change of Control Offer upon
a Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements described
in the indenture applicable to a Change of Control Offer made by Worldwide Fiber
and purchases all notes validly tendered and not withdrawn under the Change of
Control Offer.

     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of Worldwide Fiber and its Subsidiaries taken as a whole. Although
there is a limited body of case law interpreting the phrase "substantially all,"
there is no precise established definition of the phrase under applicable law.
Accordingly, the ability of a holder of notes to require Worldwide Fiber to
repurchase the notes as a result of a sale, lease, transfer, conveyance or other
disposition of less than all of the assets of Worldwide Fiber and its
Subsidiaries taken as a whole to another Person or group may be uncertain.

     We will comply with the requirements of Rule 14e-1 of the Exchange Act and
any other securities laws and regulations under the Exchange Act, if applicable
to the repurchase of notes concerning a Change of Control Offer.

     Asset Sales

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, complete an Asset Sale unless:



                                     -100-
<PAGE>

(1)  Worldwide Fiber, or the Restricted Subsidiary, receives consideration at
     the time of the Asset Sale at least equal to the fair market value of the
     assets or Equity Interests issued or sold or otherwise disposed of;

(2)  the fair market value is determined by Worldwide Fiber's Board of Directors
     and evidenced by a resolution of the Board of Directors described in an
     Officers' Certificate delivered to the trustee; and

(3)  at least 75% of the consideration for the Asset Sale received by Worldwide
     Fiber or the Restricted Subsidiary is in the form of cash or
     Telecommunications Assets. For purposes of this provision, each of the
     following shall be considered to be cash:

     (a)  any liabilities, as shown on Worldwide Fiber's or the Restricted
          Subsidiary's most recent balance sheet, of Worldwide Fiber or any
          Restricted Subsidiary, other than contingent liabilities and
          liabilities that are by their terms subordinated to the notes, that
          are assumed by the transferee of these assets under a customary
          novation agreement that releases Worldwide Fiber or the Restricted
          Subsidiary from further liability; and

     (b)  any securities, notes or other obligations received by Worldwide Fiber
          or the Restricted Subsidiary from the transferee that are within 180
          days converted by Worldwide Fiber or the Restricted Subsidiary into
          cash, to the extent of the cash received in that conversion.

     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
Worldwide Fiber or the Restricted Subsidiary, as applicable, may apply the Net
Proceeds at its option:

(1)  to permanently repay or retire

     (a)  secured Indebtedness of Worldwide Fiber, including Indebtedness under
          Credit Facilities,

     (b)  Indebtedness of Worldwide Fiber that ranks equally with the notes but
          has a maturity date that is before the maturity date of the notes, or

     (c)  Indebtedness of any Restricted Subsidiary of Worldwide Fiber, in each
          case other than any Indebtedness owed to Worldwide Fiber or any
          Restricted Subsidiary; or

(2)  to acquire Telecommunications Assets.

Pending the final application of the Net Proceeds, Worldwide Fiber may
temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by the indenture.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute Excess Proceeds. When the
aggregate amount of Excess Proceeds exceeds $10.0 million, Worldwide Fiber will
make an Asset Sale Offer to all holders of notes and all holders of other
Indebtedness that is pari passu with the notes containing provisions similar to
those described in the indenture concerning offers to purchase or redeem with
the proceeds of sales of assets to purchase the maximum principal amount of
notes and the other pari passu Indebtedness that may be purchased out of the
Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100%
of principal amount plus accrued and unpaid interest, if any, on the notes to
the date of purchase and will be payable in cash. If any Excess Proceeds remain
after completion of an Asset Sale Offer, Worldwide Fiber may use these Excess
Proceeds for any purpose not otherwise prohibited by the indenture. If the
aggregate principal amount of notes and other pari passu



                                     -101-
<PAGE>

Indebtedness tendered into the Asset Sale Offer exceeds the amount of Excess
Proceeds, the trustee shall select the notes and the other pari passu
Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero.

Selection and Notice

     If less than all of the notes are to be redeemed at any time, the trustee
will select notes for redemption as follows:

(1)  if the notes are listed, in compliance with the requirements of the
     principal national securities exchange on which the notes are listed; or

(2)  if the notes are not so listed, on a pro rata basis, by lot or by the
     method as the trustee shall deem fair and appropriate.

     No notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each holder of notes to be redeemed at its registered
address. Notices of redemption may not be conditional.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount of the note
to be redeemed. A new note in principal amount equal to the unredeemed portion
of the original note will be issued in the name of the holder of the note upon
cancellation of the original note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on notes or portions of them called for redemption.

Material Covenants

     Default or Event of Default shall have occurred and be continuing or would
     occur as a consequence of the Restricted Payment; and

(2)  Worldwide Fiber would, at the time of the Restricted Payment and after

          only to the extent the interest, dividends, repayments or other
          transfers of property are not included in the calculation of
          Consolidated Net Income, in each case to Worldwide Fiber or any of its
          Restricted Subsidiaries from any Person, including, without
          limitation, from Unrestricted Subsidiaries of Worldwide Fiber, or from
          redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
          (in each case, valued as provided in the definition of "Investments"),

     shall be excluded from clause (3)(b) of the preceding paragraph;

(3)  the defeasance, redemption, repurchase or other acquisition of subordinated
     Indebtedness of Worldwide Fiber with the net cash proceeds from an

     employees, officers or directors;

(6)  Investments in Telecommunications Assets, provided that the aggregate fair
     market value of the Investment, when taken together with all other
     Investments made under this clause (6) (measured on the date each
     Investment was made), does not exceed $15.0 million, and provided further
     however, that either Worldwide Fiber or any of its Restricted Subsidiaries,
     after giving effect to the Investments will own at least 20% of the Voting

(7)  Permitted Fiber Investments in Telecommunications Assets;

(8)  Investments in any Unrestricted Subsidiary of Worldwide Fiber, if either

<PAGE>

     positive, accrued on a cumulative basis during the period (taken as one

(12) other Restricted Payments in an aggregate amount not to exceed $20.0
     million; and

(13) the repurchase of Equity Interests of Worldwide Fiber considered to occur
     upon the exercise of stock options if the Equity Interests represent a

provided, however, that at the time of, and after giving effect to, any
Restricted Payment permitted under clauses (2), (3), (4), (5), (8)(b), (10),
(11) and (12) above, no Default in the payment of interest on the notes or Event
of Default exists or would occur as a consequence thereof.

     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by Worldwide Fiber or the Restricted
Subsidiary under the Restricted Payment. The fair market value of any assets or
securities that are required to be valued by this covenant shall be determined
by the Board of Directors whose resolution concerning the fair market value of
any assets shall be delivered to the trustee. The Board of Directors'
determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $15.0 million. No opinion or appraisal shall be
required for any Restricted Payment made under clause (7) above. In any year in
which Worldwide Fiber makes one or more Restricted Payments, Worldwide Fiber
shall include in its compliance certificate to the trustee a certification
stating that all of the Restricted Payments are, or were, permitted by the
indenture and shall set forth the basis upon which the calculations required by
this "Restricted Payments" covenant were computed, together with a copy of any
fairness opinion or appraisal required by the indenture.

     Incurrence of Indebtedness and Issuance of Preferred Stock

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to any Indebtedness (including Acquired Debt), and Worldwide Fiber
will not issue any Disqualified Stock and will not permit any of its Restricted
Subsidiaries to issue any shares of preferred stock; provided, however, that
Worldwide Fiber may incur Indebtedness (including Acquired Debt) and issue
Disqualified Stock and any Restricted Subsidiary may incur Acquired Debt, if
either:

(1)  the Consolidated Leverage Ratio at the end of Worldwide Fiber's most
     recently ended full fiscal quarter (the "Reference Period") for which a
     consolidated balance sheet of Worldwide Fiber is available immediately
     preceding the date on which the additional Indebtedness is incurred or the
     Disqualified Stock is issued would have been less than 5.5 to 1.0,
     determined on a pro forma basis, including a pro forma application of the
     net proceeds therefrom, as if the additional Indebtedness had been
     incurred, or the Disqualified Stock had been issued at the beginning of the
     Reference Period; or

(2)  the Consolidated Capital Ratio at the end of the Reference Period would
     have been less than 2.0 to 1.0, determined after giving effect to the
     incurrence or issuance of the Indebtedness or Disqualified Stock and, to
     the extent described in the definitions used in this prospectus, on a pro
     forma basis, including, to the extent described in the definitions used in
     this prospectus, a pro forma application of the net proceeds therefrom.

     The first paragraph of this covenant will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted Debt"):



                                     -105-

(1)  the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of
     Indebtedness under Credit Facilities or Permitted Vendor Facilities;

     Worldwide Fiber and its Restricted Subsidiaries outstanding under all
     Credit Facilities or Permitted Vendor Facilities after giving effect to the
     incurrence (with letters of credit being considered to have a principal
     amount equal to the maximum potential liability of Worldwide Fiber
     thereunder) does not exceed an amount equal to $200.0 million less the
     aggregate amount of all Net Proceeds of Asset Sales applied by Worldwide
     Fiber or any of its Restricted Subsidiaries since the Issue Date to
     permanently repay Indebtedness under a Credit Facility under the covenant
     described above under the caption "--Repurchase at the Option of
     Holders--Asset Sales";

     that the amount thereof does not exceed 100% of Worldwide Fiber's and its
     Restricted Subsidiaries' aggregate cost, determined in accordance with GAAP
     in good faith by the Board of Directors of Worldwide Fiber, of the
     construction, acquisition, development, engineering, installation and
     improvement of the applicable Telecommunications Assets and (B) in the case
     of the incurrence of either Purchase Money Indebtedness or Vendor Financing
     Indebtedness by a Restricted Subsidiary, such Indebtedness shall be
     Qualified Subsidiary Indebtedness;

(5)  the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of
     Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
     which are used to refund, refinance or replace, Indebtedness (other than

(6)  the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of
     intercompany Indebtedness between or among Worldwide Fiber and any of its
     Restricted Subsidiaries and the issuance of preferred stock by a Restricted
     Subsidiary to Worldwide Fiber or another Restricted Subsidiary of Worldwide
     Fiber; provided, however, that:

     (a)  if Worldwide Fiber is the obligor on the Indebtedness, the
          Indebtedness must be expressly subordinated to the prior payment in
          full in cash of all Obligations with respect to the notes; and

     (b)  (i) any subsequent issuance or transfer of Equity Interests that
          results in the Indebtedness or preferred stock being held by a Person
          other than Worldwide Fiber or a Restricted Subsidiary of Worldwide
          Fiber and (ii) any sale or other transfer of the Indebtedness or
          preferred stock to a Person that is not either Worldwide Fiber or a
          Restricted Subsidiary of Worldwide Fiber; shall be considered, in each
          case, to constitute an incurrence of the Indebtedness by Worldwide
          Fiber or the Restricted Subsidiary that was not permitted by this
          clause (6);

(7)  the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of

     Indebtedness or foreign currency based Indebtedness, respectively, that is
     permitted by the terms of this indenture to be outstanding; provided that
     the notional amount of the Hedging Obligation does not exceed the amount of
     Indebtedness or other liability to which the Hedging Obligation relates;

     Fiber that was permitted to be incurred by another provision of this
     covenant;

(9)  the accrual of interest, accretion or amortization of original issue
     discount, the payment of interest on any Indebtedness in the form of
     additional Indebtedness with the same terms, and the payment of dividends
     on Disqualified Stock in the form of additional shares of the same class of
     Disqualified Stock, if, in each case, the amount of Disqualified Stock is
     included in Fixed Charges of Worldwide Fiber as accrued;

(10) Worldwide Fiber and its Restricted Subsidiaries may incur Indebtedness
     solely for bankers acceptances, letters of credit and performance bonds or
     similar arrangements, all in the ordinary course of business (other than to
     the extent not supporting Indebtedness); (11) the incurrence by Worldwide
     Fiber or any of its Restricted Subsidiaries arising from agreements of
     Worldwide Fiber or any of its Restricted Subsidiaries providing for
     indemnification, adjustment of purchase price, earn out or other similar
     obligation, in each case, incurred or assumed in connection with the
     disposition of any business, assets or Restricted Subsidiary of Worldwide
     Fiber or any of its Restricted Subsidiaries, other than guarantees of
     Indebtedness incurred by any Person acquiring all or any portion of the
     business, assets or Restricted Subsidiary to finance the acquisition;

(12) the incurrence of Indebtedness by Foreign Subsidiaries not to exceed $10.0
     million or the equivalent amount thereof, in other foreign currencies;

(13) Worldwide Fiber or any of its Restricted Subsidiaries may incur Permitted
     ROW Indebtedness;

(14) the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of
     Acquired Debt in an aggregate amount not to exceed $10.0 million at any

     two times the net cash proceeds received by Worldwide Fiber after the Issue
     Date from the issuance and sale of its Equity Interest (other than
     Disqualified Stock) to a Person that is not a Subsidiary of Worldwide
     Fiber, to the extent such net cash proceeds have not been used pursuant to
     (A) clause 3(b) of the first paragraph of the "Restricted Payments"
     covenant described above to or (B) clauses (2) or (4) of the second
     paragraph of the "Restricted Payments" covenant described above to make a
     Restricted Payment; and

(16) the incurrence by Worldwide Fiber or any of its Restricted Subsidiaries of
     additional Indebtedness in an aggregate principal amount (or accreted
     value, as applicable) at any time outstanding not to exceed $15.0 million.

     Indebtedness or preferred stock of any Person which is outstanding at the
time the Person becomes a Restricted Subsidiary of Worldwide Fiber (including
upon designation of any Subsidiary or other Person as a Restricted Subsidiary)
or is merged with or into or consolidated with Worldwide Fiber or a Restricted
Subsidiary of Worldwide Fiber shall be considered to have been incurred at the
time the Person becomes a Restricted Subsidiary of Worldwide Fiber or is merged
with or into or consolidated with Worldwide Fiber or a Restricted Subsidiary of
Worldwide Fiber, as applicable.

     Worldwide Fiber will not incur any Indebtedness (including Permitted Debt)
that is contractually subordinated in right of payment to any other Indebtedness
of Worldwide Fiber unless the Indebtedness is also contractually subordinated in
right of payment to the notes on substantially identical terms; provided,
however, that



                                     -107-
<PAGE>

no Indebtedness of Worldwide Fiber shall be considered to be contractually
subordinated in right of payment to any other Indebtedness of Worldwide Fiber
solely by being unsecured.

     Notwithstanding any other provisions of this covenant, the maximum amount
of Indebtedness that Worldwide Fiber or a Restricted Subsidiary may incur shall
not be considered to be exceeded solely as a result of fluctuations in the
exchange rates of currencies.

     For purposes of determining compliance with this "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant, if an item of proposed
Indebtedness meets the criteria of more than one of the categories of Permitted
Debt described in clauses (1) through (16) above, or is entitled to be incurred
under the first paragraph of this covenant, Worldwide Fiber will be permitted to
classify the item of Indebtedness on the date of its incurrence in any manner
that complies with this covenant.

     Liens

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind on any asset now owned or hereafter acquired, except
Permitted Liens, without providing that the notes shall be secured equally and
ratably with the Indebtedness so secured for so long as the obligations are so
secured.

     Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to:

(1)  pay dividends or make any other distributions on its Capital Stock to
     Worldwide Fiber or any of Worldwide Fiber's Restricted Subsidiaries, or

restrictions existing under or because of:

(1)  Existing Indebtedness as in effect on the Issue Date and any amendments,
     modifications, restatements, renewals, increases, supplements, refundings,
     replacements or refinancings thereof, provided that such amendments,
     modifications, restatements, renewals, increases, supplements, refundings,
     replacement or refinancings are no more restrictive, taken as a whole, with
     respect to such dividend and other payment restrictions than those
     contained in the Existing Indebtedness, as in effect on the Issue Date;

(2)  the Credit Facilities, the indenture, the notes and the Series B Notes,
     Qualified Subsidiary Indebtedness and Indebtedness ranking pari passu with

     with the Notes such provisions are no more restrictive than those set forth
     in the notes;

(3)  applicable law;



                                     -108-

     by Worldwide Fiber or any of its Restricted Subsidiaries as in effect at
     the time of the acquisition (except to the extent the Indebtedness was
     incurred in connection with or in contemplation of the acquisition), which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person, or the property
     or assets of the Person, so acquired, if, in the case of Indebtedness, the
     Indebtedness was permitted by the terms of the indenture to be incurred;

(5)  customary non-assignment provisions restricting subletting or assignment in
     leases or other agreements entered into in the ordinary course of business
     and consistent with past practices;

     business that impose restrictions on the property so acquired of the nature
     described in clause (3) of the preceding paragraph;

(7)  any agreement for the sale or other disposition of a Restricted Subsidiary
     that restricts distributions by the Restricted Subsidiary pending its sale
     or other disposition, provided that the consummation of the transaction
     would not result in a Default or an Event of Default, that the restriction
     terminates if the transaction is not completed and that the completed or
     abandonment of the transaction occurs within one year of the date the
     agreement was entered into;

(8)  Permitted Refinancing Indebtedness, provided that the restrictions
     contained in the agreements governing the Permitted Refinancing
     Indebtedness are no more restrictive, taken as a whole, than those
     contained in the agreements governing the Indebtedness being refinanced;

(9)  Liens securing Indebtedness otherwise permitted to be incurred under the
     provisions of the covenant described above under the caption "--Liens" that
     limit the right of Worldwide Fiber or any of its Restricted Subsidiaries to
     dispose of the assets subject to the Lien;

     property in joint venture agreements and other similar agreements entered
     into in the ordinary course of business;

(11) restrictions on cash or other deposits or net worth imposed by customers
     under contracts entered into in the ordinary course of business;

(12) encumbrances and restrictions in Indebtedness incurred by Foreign
     Subsidiaries in accordance with the covenant described above under the
     caption "Incurrence of Indebtedness and Issuance of Preferred Stock"; and

(13) any Indebtedness or any agreement pursuant to which such Indebtedness was
     issued if (A) the encumbrance or restriction applies only upon a payment or
     financial covenant default or event of default contained in such
     Indebtedness or agreement and (B) the encumbrance or restriction is not
     materially more disadvantageous to the holders of the Notes than is
     customary in comparable financings (as determined in good faith by the
     Board of Directors of Worldwide Fiber).

     Amalgamation, Merger, Consolidation, or Sale of Assets

     Worldwide Fiber may not, directly or indirectly: (1) amalgamate or
consolidate or merge with or into another Person (whether or not Worldwide Fiber

(2)  the Person formed by or surviving any the amalgamation, consolidation or
     merger (if other than Worldwide Fiber) or the Person to which the sale,
     assignment, transfer, conveyance or other disposition shall have been made
     assumes all the obligations of Worldwide Fiber under the notes, the Series
     B Notes, the indenture and the registration rights agreement under
     agreements reasonably satisfactory to the trustee;

(3)  no Default or Event of Default (or an event that, with the passing of time
     or giving of notice or both, would constitute an Event of Default) shall
     exist or shall occur immediately after giving effect on a pro forma basis
     to the transaction;

(4)  the transaction will not result in Worldwide Fiber or the Person formed by
     or surviving the amalgamation, consolidation or merger (if other than
     Worldwide Fiber) being required to make any deduction or withholding on
     account of Taxes as described under the caption "Redemption for Changes in
     Canadian Withholding Taxes" and "Payment of Additional Amounts" from any
     payment under or for the notes that Worldwide Fiber would not have been
     required to make had the transaction or series of related transactions not
     occurred;

(5)  except in the case of the amalgamation, consolidation or merger of
     Worldwide Fiber with or into a Wholly-Owned Restricted Subsidiary,
     Worldwide Fiber or the Person formed by or surviving any amalgamation,
     consolidation or merger (if other than Worldwide Fiber) will, on the date
     of the transaction after giving pro forma effect to the transaction and any
     related financing transactions as if the same had occurred at the beginning
     of the applicable four-quarter period, be permitted to incur at least $1.00
     of additional Indebtedness under clause (1) or (2) of the first paragraph
     of the covenant described above under the caption "--Incurrence of
     Indebtedness and Issuance of Preferred Stock"; and

(6)  Worldwide Fiber shall have delivered to the trustee an Officers'
     Certificate and an opinion of counsel, each stating that the amalgamation,
     consolidation, merger or transfer and the supplemental indenture, if any,
     comply with the indenture.

     In addition, Worldwide Fiber may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This "Amalgamation, Merger, Consolidation, or
Sale of Assets" covenant will not apply to a sale, assignment, transfer,
conveyance or other disposition of assets between or among Worldwide Fiber and
any of its Wholly-Owned Restricted Subsidiaries.

     Upon any amalgamation, consolidation or merger or any transfer of all or
substantially all of the assets of Worldwide Fiber in accordance with the above,
the successor corporation formed by the amalgamation or consolidation or into
which Worldwide Fiber is merged or to which the transfer is made shall succeed
to and (except in the case of a lease) be substituted for, and may exercise
every right and power of, Worldwide Fiber under the indenture with the same
effect as if the successor corporation had been named in the Indenture as
Worldwide Fiber, and (except in the case of a lease) Worldwide Fiber shall be
released from the obligations under the notes, and the indenture except with
respect to any obligations that arise from, or are related to, such transaction.

     For purposes of the above, the transfer (by assignment, sale or otherwise)
of all or substantially all of the properties and assets of one or more
Subsidiaries, Worldwide Fiber's interest in which constitutes all or
sub-



                                     -110-
<PAGE>

stantially all of the properties and assets of Worldwide Fiber, shall be
considered to be the transfer of all or substantially all of the properties and
assets of Worldwide Fiber.

     Transactions with Affiliates

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties, assets or securities to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

(1)  such Affiliate Transaction is on terms that are no less favorable to
     Worldwide Fiber or the relevant Restricted Subsidiary than those that would
     have been obtained in a comparable transaction by Worldwide Fiber or such
     Restricted Subsidiary with a Person that is not an Affiliate; and

(2)  Worldwide Fiber delivers to the trustee:

     (a)  with respect to any Affiliate Transaction or series of related
          Affiliate Transactions involving aggregate consideration in excess of
          $5.0 million, a resolution of the Board of Directors described in an
          Officers' Certificate certifying that such Affiliate Transaction
          complies with this covenant and that such Affiliate Transaction has
          been approved by a majority of the disinterested members of the Board
          of Directors and is in the best interests of Worldwide Fiber or such
          Restricted Subsidiary; and

     (b)  with respect to any Affiliate Transaction or series of related
          Affiliate Transactions involving aggregate consideration in excess of
          $10.0 million, an opinion as to the fairness to the holders of such
          Affiliate Transaction from a financial point of view issued by an
          accounting, appraisal or investment banking firm of national standing.

     The following items shall not be considered to be Affiliate Transactions
and, therefore, will not be subject to the provisions of the prior paragraph:

(1)  reasonable fees and compensation paid to, and indemnity provided on behalf
     of, our officers, directors, employees, agents or consultants or any of our
     Restricted Subsidiaries as determined in good faith by the Board of
     Directors or senior management of Worldwide Fiber;

(2)  transactions between or among us and any of our Restricted Subsidiaries;

(3)  any sale or other issuance of our Equity Interests (other than Disqualified
     Stock);

(4)  Restricted Payments that are permitted by the provisions of the indenture
     described above under the caption "--Restricted Payments" or by clauses
     (1), (3), (6), (7) or (8) of the definition of "Permitted Investments"; and

(5)  any agreement or arrangement as in effect on the Issue Date or any
     amendment thereto or any transaction contemplated thereby (including
     pursuant to any amendment thereto) in any replacement agreement or
     arrangement thereto so long as any such amendment or replacement agreement
     or arrangement is not more disadvantageous to Worldwide Fiber or its
     Restricted Subsidiaries, as the case may be, in any material respect than
     the original agreement as in effect on the Issue Date.

     Issuances of Guarantees by Restricted Subsidiaries

     Worldwide Fiber will not permit any Restricted Subsidiary, directly or
indirectly, to guarantee, assume or in any other manner become liable with
respect to any Indebtedness of Worldwide Fiber which is pari passu (other than
any Indebtedness incurred under a Credit Facility) with or subordinate in right
of payment to the notes ("Guaranteed Indebtedness), unless:

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

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

     Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (1) any sale, exchange or transfer,
to any Person that is not an Affiliate of Worldwide Fiber, of all of Worldwide
Fiber's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all of the assets of, the Restricted Subsidiary (which sale,
exchange or transfer is not prohibited by the indenture) or (2) the release or
discharge of the guarantee which resulted in the creation of the Subsidiary
Guarantee, except a discharge or release by or as a result of payment under the
guarantee.

     Designation of Restricted and Unrestricted Subsidiaries

     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, all
outstanding Investments owned by Worldwide Fiber and its Restricted Subsidiaries
in the Subsidiary so designated will be considered to be an Investment made as
of the time of such designation and will reduce the amount available for
Restricted Payments under the first paragraph of the covenant described above
under the caption "--Restricted Payments." All such outstanding Investments will
be valued at their fair market value at the time of such designation. That
designation will only be permitted if the Restricted Payment would be permitted
at that time and if the Restricted Subsidiary otherwise meets the definition of
an Unrestricted Subsidiary. The Board of Directors may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would
not cause a Default and such redesignation will increase the amount available
for Restricted Payments under the first paragraph of the covenant described
under the caption "--Restricted Payments" as provided in the covenant described
under the caption "--Restricted Payments" or Permitted Investments, as
applicable.

     Business Activities

     Worldwide Fiber will not, and will not permit any Restricted Subsidiary to,
engage to any material extent in any business other than the Telecommunications
Business.



                                     -112-
<PAGE>

     Payments for Consent

     Worldwide Fiber will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any holder of notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the indenture or the notes unless
the consideration is offered to be paid and is paid to all holders of the notes
that consent, waive or agree to amend in the time frame described in the
solicitation documents relating to the consent, waiver or agreement.

     Reports

     For so long as any notes remain outstanding, Worldwide Fiber will furnish
to the holders the information required to be delivered under Rule 144A(d)(4)
under the Securities Act. Whether or not Worldwide Fiber is subject to Section
13(a) or 15(d) of the Exchange Act, Worldwide Fiber shall file with the
Securities and Exchange Commission and furnish to the holders and the trustee
(1) within 140 days after the end of each fiscal year, annual reports on Form
20-F or 40-F, as applicable (or any successor form), containing the information
required to be contained in the annual reports (or required in such successor
form) and (2) (a) within 45 days after the end of each of the first three fiscal
quarters of each fiscal year, reports on Form 10-Q or (b) within 60 days after
the end of each of the first three fiscal quarters of each fiscal year, reports
on Form 6-K (or any successor form) which, regardless of applicable
requirements, shall, at a minimum, contain a "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

Events of Default and Remedies

     Each of the following is an Event of Default:

(1)  default for 30 days in the payment when due of interest on, or Additional
     Amounts, if any, concerning, the notes;

(2)  default in payment when due of the principal of or premium, if any, on the
     notes;

(3)  failure by Worldwide Fiber or any of its Restricted Subsidiaries to comply
     with the provisions described under the caption "--Amalgamation, Merger,
     Consolidation, or Sale of Assets";

(4)  failure by Worldwide Fiber or any of its Restricted Subsidiaries for 15
     days after written notice thereof has been given to Worldwide Fiber by the
     trustee or to Worldwide Fiber and the trustee by holders of at least 25% of
     the aggregate principal amount of the notes outstanding to comply with the
     provisions described under the captions "--Repurchase at the Option of
     Holders--Change of Control" or "--Asset Sales;"

(5)  failure by Worldwide Fiber or any of its Restricted Subsidiaries for 60
     days after written notice thereof has been given to Worldwide Fiber by the
     trustee or to Worldwide Fiber and the trustee by holders of at least 25% of
     the aggregate principal amount of the notes outstanding to comply with any
     of the other agreements in the indenture or the notes;

(6)  the voluntary relinquishment by Worldwide Fiber of any of its rights under
     the Non-Competition Agreement or the failure by Worldwide Fiber for 30 days
     after written notice has been given to Worldwide Fiber by the trustee or to
     Worldwide Fiber and the trustee by holders of at least 25% of the aggregate
     principal amount of the notes outstanding to enforce any of such rights, in
     each case which is materially detrimental to the interests of Worldwide
     Fiber or the holders;



                                     -113-
<PAGE>

(7)  default under any mortgage, indenture or instrument under which there may
     be issued or by which there may be secured or evidenced any Indebtedness
     for money borrowed by Worldwide Fiber or any of its Restricted Subsidiaries
     (or the payment of which is guaranteed by Worldwide Fiber or any of its
     Restricted Subsidiaries) whether such Indebtedness or guarantee now exists,
     or is created after the Issue Date, if that default:

     (a)  is caused by a failure to pay principal of or premium, if any, on such
          Indebtedness before the expiration of the grace period provided in
          such Indebtedness on the date of the default (a "Payment Default"); or

     (b)  results in the acceleration of such Indebtedness before its express
          maturity,

     and, in each case, the principal amount of such Indebtedness, together with
     the principal amount of any other such Indebtedness under which there has
     been a Payment Default or the maturity of which has been so accelerated,
     aggregates $10.0 million or more;

(8)  failure by Worldwide Fiber or any of its Restricted Subsidiaries to pay
     final judgments which are non-appealable aggregating in excess of $10.0
     million (net of applicable insurance coverage which is acknowledged in
     writing by the insurer), which judgments are not paid, discharged or stayed
     for a period of 60 days; and

(9)  certain events of bankruptcy or insolvency concerning Worldwide Fiber or
     any of its Restricted Subsidiaries.

     In the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to Worldwide Fiber, any Restricted
Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary,
all outstanding notes will become due and payable immediately without further
action or notice. If any other Event of Default occurs and is continuing, the
trustee by notice to Worldwide Fiber or the holders of at least 25% in principal
amount of the then outstanding notes by notice to Worldwide Fiber and the
trustee may declare all the notes to be due and payable immediately.

     Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture. Subject to certain limitations, holders of a majority
in principal amount of the then outstanding notes may direct the trustee in its
exercise of any trust or power. The trustee may withhold from holders of the
notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest.

     The holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the trustee may on behalf of the holders of all of the
notes waive any existing Default or Event of Default and its consequences under
the indenture except a continuing Default or Event of Default in the payment of
premium, if any, or interest on, or the principal of, the notes.

     Worldwide Fiber is required to deliver to the trustee annually a statement
regarding compliance with the indenture. Upon becoming aware of any Default or
Event of Default, Worldwide Fiber is required to deliver to the trustee a
statement specifying the Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

     No director, officer, employee, incorporator or stockholder of Worldwide
Fiber or any of its Subsidiaries shall have any liability for any obligations of
Worldwide Fiber or its Subsidiaries under the notes, the inden-



                                     -114-
<PAGE>

ture or for any claim based on, for, or because of, such obligations or their
creation. Each holder of notes by accepting a note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the notes. The waiver may not be effective to waive liabilities under the
federal securities laws.

Legal Defeasance and Covenant Defeasance

     Worldwide Fiber may, at its option and at any time, elect to have all of
its obligations discharged with respect to the outstanding notes ("Legal
Defeasance") except for:

(1)  the rights of holders of outstanding notes to receive payments for the
     principal of, premium, if any, and interest on the notes when the payments
     are due from the trust referred to below;

(2)  Worldwide Fiber's obligations with respect to the notes concerning issuing
     temporary notes, registration of notes, mutilated, destroyed, lost or
     stolen notes and the maintenance of an office or agency for payment and
     money for security payments held in trust;

(3)  the rights, powers, trusts, duties and immunities of the trustee, and
     Worldwide Fiber's obligations in connection the rights, powers, trusts,
     duties and immunities of the trustee;

(4)  the Legal Defeasance provisions of the indenture; and

(5)  Worldwide Fiber's obligation to pay Additional Amounts.

     In addition, Worldwide Fiber may, at its option and at any time, elect to
have the obligations of Worldwide Fiber released concerning certain covenants
that are described in the indenture ("Covenant Defeasance") and after the
election any omission to comply with those covenants shall not constitute a
Default or Event of Default concerning the notes. In the event Covenant
Defeasance occurs, certain events, not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events, described under "Events of
Default" will no longer constitute an Event of Default concerning the notes.

     In order to exercise either Legal Defeasance or Covenant Defeasance:

(1)  Worldwide Fiber must irrevocably deposit with the trustee, in trust, for
     the benefit of the holders of the notes, cash in U.S. dollars, non-callable
     Government Securities, or a combination of cash and non-callable Government
     Securities, in such amounts as will be sufficient, in the opinion of a
     nationally recognized firm of independent public accountants, to pay the
     principal of, premium, if any, and interest on the outstanding notes on the
     stated maturity or on the applicable redemption date and Worldwide Fiber
     must specify whether the notes are being defeased to maturity or to a
     particular redemption date;

(2)  in the case of Legal Defeasance, Worldwide Fiber shall have delivered to
     the trustee an Opinion of Counsel reasonably acceptable to the trustee
     confirming that (a) Worldwide Fiber has received from, or there has been
     published by, the Internal Revenue Service a ruling or (b) since the Issue
     Date, there has been a change in the applicable federal income tax law, in
     either case to the effect that, and based on an IRS ruling or applicable
     federal income tax law such opinion of counsel shall confirm that, the
     holders of the outstanding notes will not recognize income, gain or loss
     for United States federal income tax purposes as a result of the



                                     -115-
<PAGE>

     Legal Defeasance and will be subject to United States federal income tax on
     the same amounts, in the same manner and at the same times as would have
     been the case if the Legal Defeasance had not occurred and Worldwide Fiber
     shall have delivered to the trustee an opinion of counsel in Canada
     reasonably acceptable to the trustee confirming that the holders of the
     outstanding notes will not recognize income, gain or loss for Canadian
     federal income tax purposes as a result of the Legal Defeasance and will be
     subject to Canadian federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if the Legal
     Defeasance had not occurred;

(3)  in the case of Covenant Defeasance, Worldwide Fiber shall have delivered to
     the trustee an Opinion of Counsel reasonably acceptable to the trustee
     confirming that the holders of the outstanding notes will not recognize
     income, gain or loss for United States federal income tax purposes as a
     result of the Covenant Defeasance and will be subject to United States
     federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if the Covenant Defeasance had not
     occurred and Worldwide Fiber shall have delivered to the trustee an opinion
     of counsel in Canada reasonably acceptable to the trustee confirming that
     the holders of the outstanding notes will not recognize income, gain or
     loss for Canadian federal income tax purposes as a result of the Covenant
     Defeasance and will be subject to Canadian federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if the Covenant Defeasance had not occurred;

(4)  no Default or Event of Default shall have occurred and be continuing
     either: (a) on the date of the deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to the
     deposit); or (b) or insofar as Events of Default from bankruptcy or
     insolvency events are concerned, at any time in the period ending on the
     91st day after the date of deposit;

(5)  the Legal Defeasance or Covenant Defeasance will not result in a breach or
     violation of, or constitute a default under any material agreement or
     instrument (other than the indenture) to which Worldwide Fiber or any of
     its Restricted Subsidiaries is a party or by which Worldwide Fiber or any
     of its Restricted Subsidiaries is bound;

(6)  Worldwide Fiber must have delivered to the trustee an opinion of counsel to
     the effect that after the 91st day following the deposit, the trust funds
     will not be subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally;

(7)  Worldwide Fiber must deliver to the trustee an Officers' Certificate
     stating that the deposit was not made by Worldwide Fiber with the intent of
     preferring the holders of notes over the other creditors of Worldwide Fiber
     with the intent of defeating, hindering, delaying or defrauding creditors
     of Worldwide Fiber or others; and

(8)  Worldwide Fiber must deliver to the trustee an Officers' Certificate and an
     opinion of counsel, in the case of the Officers' Certificate, stating that
     all conditions precedent relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with and, in the case of the opinion of
     counsel, that the conditions precedent in clauses (1) (concerning the
     validity and perfection of the security interest), (2), (3) and (5) have
     been complied with.

Indemnification for Judgment Currency Fluctuations

     The obligations of Worldwide Fiber to any holder of notes shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
U.S. dollars (the "Agreement Currency"), be discharged only to the extent that
on the day following receipt by the holder of notes or the trustee of any amount
in the Judgment Currency, the holder of notes may in accordance with normal
banking procedures purchase the Agreement Currency with the Judgment Currency.
If the amount of the Agreement Currency so purchased is less than the amount
originally to be paid to the holder of notes or the trustee in the Agreement
Currency, Worldwide Fiber will pay the difference and if the amount of the
Agreement Currency so purchased exceeds the amount originally to be paid to the
holder of notes or the trustee the holder of notes or the trustee will pay to or
for the account of Worldwide Fiber the excess, provided that the holder of notes
or the trustee shall not have any obliga-



                                     -116-
<PAGE>

tion to pay the excess as long as a Default by Worldwide Fiber in its
obligations under the notes or the indenture has occurred and is continuing, in
which case the excess may be applied by the holder of notes to such obligations.

Satisfaction and Discharge

     The indenture will be discharged and will cease to be of further effect as
to all notes issued thereunder, when either (a) all such notes theretofore
authenticated and delivered (except lost, stolen or destroyed notes which have
been replaced or paid and notes for whose payment money has theretofore been
deposited in trust and thereafter repaid to Worldwide Fiber) have been delivered
to the Trustee for cancellation; or (b)(i) all such Notes not theretofore
delivered to such trustee for cancellation have become due and payable by reason
of the making of a notice of redemption or otherwise or will become due and
payable within one year and we or a Subsidiary Guarantor, if any, has
irrevocably deposited or caused to be deposited with such Trustee as trust funds
in trust an amount of money sufficient to pay and discharge the entire
Indebtedness on such notes not theretofore delivered to the Trustee for
cancellation for principal, premium, if any, and accrued interest to the date of
maturity or redemption; (ii) no Default or Event of Default with respect to the
indenture or the notes shall have occurred and be continuing on the date of such
deposit or shall occur as a result of such deposit and such deposit will not
result in a breach or violation of, or constitute a default under, any other
instrument to which we or a Subsidiary Guarantor, if any, is a party or by which
we or a Subsidiary Guarantor, if any, is bound; (iii) we or a Subsidiary
Guarantor, if any, has paid or caused to be paid all sums payable by it under
the indenture; and (iv) we have delivered irrevocable instructions to the
trustee under the indenture to apply the deposited money toward the payment of
such notes at maturity or the redemption date, as the case may be.

     In addition, we must deliver an Officer's Certificate and an opinion of
counsel to the trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

Amendment, Supplement and Waiver

     With the consent of holders of not less than a majority in aggregate
principal amount of the notes at the time outstanding, Worldwide Fiber and the
trustee are permitted to amend or supplement the indenture or any supplemental
indenture or modify the rights of the holders; provided that without the consent
of each holder affected, no amendment, supplement, modification or waiver may
(concerning any notes held by a non-consenting holder):

(1)  reduce the principal amount of notes whose holders must consent to an
     amendment, supplement or waiver;

(2)  reduce the principal of or change the fixed maturity of any note or alter
     the provisions concerning the redemption of the notes (other than
     provisions relating to the covenants described above under the caption
     "--Repurchase at the Option of Holders");

(3)  reduce the rate of or change the time for payment of interest on any note;

(4)  waive a Default or Event of Default in the payment of principal of or
     premium, if any, or interest on the notes (except a rescission of
     acceleration of the notes by the holders of at least a majority in
     aggregate principal amount of the notes and a waiver of the payment default
     that resulted from such acceleration);

(5)  make any note payable in money other than that stated in the notes;

(6)  make any change in the provisions of the indenture relating to waivers of
     past Defaults or the rights of holders of notes to receive payments of
     principal of or premium, if any, or interest on the notes;



                                     -117-
<PAGE>

(7)  waive a redemption payment concerning any note (other than a payment
     required by one of the covenants described above under the caption
     "--Repurchase at the Option of Holders");

(8)  cause the notes to become subordinate in right of payment to any other
     Indebtedness;

(9)  make any change that would adversely affect the rights of the holders to
     receive Additional Amounts;

(10) modify the obligation of Worldwide Fiber to make a Change of Control Offer
     to purchase notes after the occurrence of an event which constitutes a
     Change of Control; or

(11) make any change in the preceding amendment and waiver provisions.

     Notwithstanding the preceding, without the consent of any holder of notes,
Worldwide Fiber and the trustee may amend or supplement the indenture or the
notes:

(1)  to cure any ambiguity, defect or inconsistency;

(2)  to provide for uncertificated notes in addition to or in place of
     certificated notes;

(3)  to provide for the assumption of Worldwide Fiber's obligations to holders
     of notes in the case of a merger or consolidation or sale of all or
     substantially all of Worldwide Fiber's assets;

(4)  to make any change that would provide any additional rights or benefits to
     the holders of notes or that does not adversely affect the legal rights
     under the indenture of any such holder; or

(5)  to comply with requirements of the Securities and Exchange Commission to
     effect or maintain the qualification of the indenture under the Trust
     Indenture Act.

Concerning the Trustee

     If the trustee becomes one of our creditors, the indenture limits its right
to obtain payment of claims in certain cases, or to realize on certain property
received in respect of any such claim as security or otherwise. The trustee will
be permitted to engage in other transactions; however, if it acquires any
conflicting interest it must eliminate the conflict within 90 days, apply to the
Securities and Exchange Commission for permission to continue or resign.

     The holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. The indenture provides that in case an Event of Default
shall occur and be continuing, the trustee will be required, in the exercise of
its power, to use the degree of care of a prudent man in the conduct of his own
affairs. Subject to such provisions, the trustee will be under no obligation to
exercise any of its rights or powers under the indenture at the request of any
holder of notes, unless the holder shall have offered to the trustee security
and indemnity satisfactory to it against any loss, liability or expense.

Governing Law

     The indenture provides that it and the notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of laws to the extent that the
application of the law of another jurisdiction would be required by principles
of conflicts of laws.

Enforceability of Judgments

     Because all or a substantial portion of our assets and the assets of our
directors and officers are located outside of 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, including judgments concerning the payment of principal,
premium, interest, Additional Amounts, Change of Control Payment, offer price,
redemption price or other amounts payable under the notes.

     Worldwide Fiber has been informed by its Canadian counsel, Farris, Vaughan,
Wills & Murphy, that the laws of the Province of British Columbia and the
federal laws of Canada applicable in the Province of British Columbia permit an
action to be brought in a court of competent jurisdiction in the Province of
British Columbia on any final and conclusive judgment in personam of any federal
or state court located in the Borough of Manhattan in The City of New York that
is not impeachable as void or voidable under the internal laws of the State of
New York for a sum certain for the enforcement of the indenture or the notes if:

     o    the court rendering the judgment had jurisdiction over the judgment
          debtor, as recognized by the Canadian Court (and submission by
          Worldwide Fiber in the indenture to the non-exclusive jurisdiction of
          the New York court will be sufficient for that purpose),

     o    the judgment was not obtained by fraud or in a manner contrary to
          natural justice and the enforcement of the judgment would not be
          inconsistent with public policy, as that term is applied by a Canadian
          Court, or contrary to any order made by the Attorney General of Canada
          under the Foreign Extraterritorial Measures Act (Canada),

     o    the enforcement of the judgment does not constitute, directly or
          indirectly, the enforcement of such foreign revenue, expropriatory or
          penal laws, and

     o    the action to enforce the judgment is commenced within the applicable
          limitation period. Worldwide Fiber has been advised by Farris,
          Vaughan, Wills & Murphy that it knows of no reason, based upon public
          policy under the laws of the Province of British Columbia and the
          federal laws of Canada applicable in the Province of British Columbia
          for avoiding recognition of a judgment of a New York court to enforce
          the indenture or the notes.

     We are a corporation organized under the laws of 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 special 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



                                     -119-
<PAGE>

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.

Consent to Jurisdiction and Service

     The indenture provides that Worldwide Fiber irrevocably appoints CT
Corporation System as its agent for service of process in any suit, action, or
proceeding concerning the indenture or the notes and for actions brought under

Borough of Manhattan in The City of New York, and submits to the non-exclusive
jurisdiction.

Indebtedness and Issuance of Preferred Stock," Worldwide Fiber shall be in
default of such covenant. The Board of Directors of Worldwide Fiber may at any
time designate any Unrestricted Subsidiary to be a Restricted Subsidiary;
provided that the designation shall be considered to be an incurrence of
Indebtedness by a Restricted Subsidiary of Worldwide Fiber of any outstanding
Indebtedness of such Unrestricted Subsidiary and the designation shall only be
permitted if (1) such Indebtedness is permitted under the covenant described
under the caption "Certain Covenants--Incurrence of Indebtedness and Issuance of
Preferred Stock," calculated on a pro forma basis as if the designation had
occurred at the beginning of the four-quarter reference period; and (2) no
Default or Event of Default would be in existence following such designation.

     "Vendor Financing Indebtedness" means Indebtedness of Worldwide Fiber
incurred under any agreements between Worldwide Fiber and one or more vendors or
lessors (or any Affiliate of any such vendor or lessor) of Telecommunications
Assets used or intended for use in a Telecommunications Business by Worldwide
Fiber providing financing for all or any part of the cost of construction,
engineering, acquisition, installation, development or improvement by Worldwide
Fiber or any Restricted Subsidiary of any Telecommunications Assets from the
vendor or lessor (or any Affiliate of such vendor or lessor) and including any
related notes, Guarantees, collateral documents, instruments and agreements
executed in connection therewith, as the same may be amended, supplemented,
modified or restated from time to time. Vendor Financing Indebtedness shall not
include any working capital facility or Indebtedness to fund interest or other
similar expenses made available by any vendor or lessor.

     "Voting Stock" of any Person as of any date means the Capital Stock of such
Person that is at the time entitled to vote in the election of the Board of
Directors of such Person.

     "Weighted Average Life to Maturity" means, when applied to any Indebtedness
at any date, the number of years obtained by dividing:

(1)  the sum of the products obtained by multiplying (a) the amount of each then
     remaining installment, sinking fund, serial maturity or other required
     payments of principal, including payment at final maturity, in respect
     thereof, by (b) the number of years (calculated to the nearest one-twelfth)
     that will elapse between the date and the making of such payment; by

(2)  the then outstanding principal amount of such Indebtedness.

     "Wholly-Owned Restricted Subsidiary" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock or other

                        DESCRIPTION OF OTHER INDEBTEDNESS

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 Notes.

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

Year                                                        Redemption Price

2003..................................................           106.250%
2004..................................................           100.000%

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

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

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

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

     Covenants. The 1998 indenture contains certain covenants that, among other
things, limit the ability of Worldwide Fiber and its restricted subsidiaries to:

     o    borrow money,



                                     -136-
<PAGE>

     o    pay dividends on stock or repurchase stock,

     o    make investments,

     o    use assets as security in other transactions, and

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

     Events of Default. The 1998 indenture contains customary events of default,
     including:

     o    defaults in the payment of principal, premium or interest,

     o    defaults in the compliance with covenants contained in the 1998
          indenture,

     o    cross defaults on more than $10 million of other indebtedness,

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

     o    the bankruptcy of Worldwide Fiber or certain of its subsidiaries.

Proposed Worldwide Fiber Inc. Credit Facility

     We have accepted a commitment letter from an affiliate of Salomon Smith
Barney Inc., one of the initial purchasers of the notes, to arrange, subject to
credit approval and final documentation, a senior secured revolving credit
facility of up to $115 million with additional senior secured revolving purchase
money facilities of $35 million. We expect the facility to close in the fourth
quarter of 1999.

     The indebtedness outstanding under the proposed credit facility would be
guaranteed by some of our subsidiaries and would be secured by all property and
assets owned by and all capital stock and intercompany indebtedness of us and
some of our subsidiaries.

     The proposed credit facility would contain various covenants which would
restrict us and our subsidiaries with respect to, among other things, incurring
indebtedness, entering into merger or consolidation transactions, disposing of
our assets, acquiring assets, making certain restricted payments, repaying the
notes, creating any liens on our assets, making investments, and entering into
sale and leaseback transactions and transactions with affiliates. The proposed
credit facility would also require that we comply with various financial
covenants, including a fixed charge coverage ratio, maximum leverage ratios and
a limit on capital expenditures. The proposed credit facility would also contain
certain events of default, including default upon the nonpayment of principal,
interest, fees or other amounts, a cross-default with respect to other
obligations of ours and our subsidiaries, failure to comply with certain
covenants, conditions or provisions under the credit facility, the existence of
certain unstayed or undischarged judgments, the occurrence of any default under
material agreements that could result in a material adverse effect on us, the
making of materially false or misleading representations or warranties, or the
commencement of reorganization, bankruptcy, insolvency or similar proceedings or
the occurrence of certain ERISA events or a change of control. Upon occurrence
and during the continuance of an event of default under the credit facility, all
obligations under the credit facility could be declared to be immediately due
and payable.

     We are likely from time to time, prior to the maturity date of the notes,
to refinance, replace, restructure, substitute for, amend or supplement the
credit facility. The actual terms of any credit facility could differ
substantially from the proposed facility outlined above.



                                     -137-
<PAGE>

Proposed Hibernia Credit Facility

     We have accepted a commitment letter from Goldman Sachs Credit Partners LP,
DLJ Capital Funding, Inc. and Credit Suisse First Boston, to arrange, subject to
certain standard conditions, including completion of definitive documentation,
up to $600 million in senior secured credit facilities consisting of two term
loan facilities aggregating $575 million and a $25 million working capital
revolving credit facility. DLJ Capital Funding, Inc. is an affiliate to
Donaldson Lufkin & Jenrette Securities Corporation, one of the initial
purchasers of the notes.

     The indebtedness outstanding under the proposed credit facility would be
borrowed by one of our subsidiaries and would be secured by all property and
assets owned by that subsidiary and relating to Hibernia. The proposed facility
would be non-recourse to Worldwide Fiber Inc. The proposed credit facility would
contain various covenants which would restrict the subsidiary to the
development, design, engineering, construction and installation of Hibernia. The
actual terms of the definitive credit facility could differ substantially from
the proposed facility outlined above.





                                     -138-
<PAGE>


                          BOOK-ENTRY, DELIVERY AND FORM

     The old notes were offered and sold to qualified institutional buyers (as
defined in Rule 144A under the Securities Act) ("QIBs") in reliance of Rule 144A
under the Securities Act or Rule 144A notes). Rule 144A notes were initially
represented by one or more notes in registered, global form without interest
coupons. The global old notes were deposited upon issuance with the trustee, as
custodian for The Depository Trust Company ("DTC"), in New York, New York, and
registered in the name of DTC or its nominee for credit to the accounts of DTC's
Direct and Indirect Participants (as defined below). Except for new notes issued
in certificated form, the new notes will be represented by one or more notes in
registered, global form without interest coupons. The global new note will be
deposited upon issuance with the trustee as custodian for DTC and registered in
the name of DTC or its nominee, in each case for credit to an account of direct
or indirect participant.

     Except as described below, the global new note may be transferred, in whole
but not in part, only to another nominee of DTC or to successor of DTC or its
nominee. Beneficial interests in the global new note may not be exchanged for
new notes in certificated form except in the limited circumstances described
below. See "--Exchange of the Global New Note for Certificated New Notes."

     The new notes may be presented for registration of transfer and exchange at
the offices of the Registrar (as defined in the indenture).

Depositary Procedures

     DTC has advised us that DTC is a limited-purpose trust company created to
hold securities for its participating organizations (collectively, the "Direct
Participants") and to facilitate the clearance and settlement of transactions in
those securities between Direct Participants through electronic book-entry
changes in accounts of Participants. The Direct Participants include securities
brokers and dealers (including the initial purchasers), banks, trust companies,
clearing corporations and certain other organizations. Access to DTC's system is
also available to other entities that clear through or maintain a direct or
indirect, custodial relationship with a Direct Participant (collectively, the
"Indirect Participants").

     DTC has also advised us that, under DTC's procedures, (1) upon deposit of
the global new note, DTC will credit the accounts of the exchanging Direct
Participants with portions of the global new note and (2) DTC will maintain
records of the ownership interests of the Direct Participants in the global new
note and the transfer of ownership interests by and between Direct Participants.
DTC will not maintain records of the ownership interests of, or the transfer of
ownership interests by and between, Indirect Participants or other owners of
beneficial interests in the global notes. Direct Participants and Indirect
Participants must maintain their own records of the ownership interests of, and
the transfer of ownership interests by and between, Indirect Participants and
other owners of beneficial interests in the global new note.

     Investors in the global new note may hold their interests in the global new
note directly through DTC if they are Direct Participants in DTC or indirectly
through organizations that are Direct Participants in DTC.

     The laws of some states in the United States require that certain persons
take physical delivery in definitive, certificated form, of securities that they
own. This may limit or curtail the ability to transfer beneficial interests in a
global new note to the persons. Because DTC can act only on behalf of Direct
Participants, which in turn act on behalf of Indirect Participants and others,
the ability of a person having a beneficial interest in a global new note to
pledge the interest to persons or entities that are not Direct Participants in
DTC, or to otherwise take actions for the interests, may be affected by the lack
of physical certificates evidencing the interests. For certain other
restrictions on the transferability of the new notes see "--Exchange of the
Global New Note for Certificated New Notes."



                                     -139-
<PAGE>

     Except as described in this prospectus, owners of beneficial interests in
the global new note will not have new notes registered in their names, will not
receive physical delivery of new notes in certificated form and will not be
considered the registered owners or holders of new notes under the indenture for
any purpose.

     Under the terms of the indenture, we and the trustee will treat the persons
in whose names the new notes are registered (including the global new note) as
the owners of the new notes for the purpose of receiving payments and for any
and all other purposes whatsoever. Payments for the principal, premium, and
interest on the global new note registered in the name of DTC or its nominee
will be payable by the trustee to DTC or its nominee as the registered holder
under the indenture. Consequently, neither we, the initial purchasers, the
trustee nor any agent of ours or the trustee has or will have any responsibility
or liability for (1) any aspect of DTC's records or any Direct Participant's or
Indirect Participant's records relating to or payments made on account of
beneficial ownership interests in the global new note or for maintaining,
supervising or reviewing any of DTC's records or any Direct Participant's or
Indirect Participant's records relating to the beneficial ownership interests in
any global new note or (2) any other matter relating to the actions and
practices of DTC or any of its Direct Participants or Indirect Participants.

     DTC has advised us that its current payment practice (for payments of
principal, interest and the like) concerning securities the as the new notes is
to credit the accounts of the relevant Direct Participants with the payment on
the payment date in amounts proportionate to the Direct Participant's respective
ownership interests in the relevant security as shown on DTC's records. Payments
by Direct Participants and Indirect Participants to the beneficial owners of the
new notes will be governed by standing instructions and customary practices
between them and will not be our responsibility or the responsibility of DTC or
the trustee. Neither we nor the trustee will be liable for any delay by DTC or
its Direct Participants or Indirect Participants in identifying the beneficial
owners of the new notes, and we and the trustee may conclusively rely on and
will be protected in relying on instructions from DTC or its nominee as the
registered owner of the global new note for all purposes.

     The global new note will trade in DTC's Same-Day Funds Settlement System
and, therefore, transfers between Direct Participants in DTC will be effected in
accordance with DTC's procedures, and will be settled in immediately available
funds. Transfers between Indirect Participants who hold an interest through a
Direct Participant will be effected in accordance with the procedures of the
Direct Participant but generally will settle in immediately available funds.

     DTC has advised us that it will take any action permitted to be taken by a
holder of new notes only at the direction of one or more Direct Participants to
whose account interests in the global new note are credited and only for the
portion of the aggregate principal amount of the new notes to which the Direct
Participant or Direct Participants has or have given direction. However, if
there is an Event of Default under the new notes, DTC reserves the right to
exchange the global new note (without the direction of one or more of its Direct
Participants) for new notes in certificated form, and to distribute the new
notes to its Direct Participants. See "--Exchange of the Global New Note for
Certificated New Notes."

     Although DTC agreed to the above procedures to facilitate transfers of
interests in the global new note among accountholders in DTC, it is under no
obligation to perform or to continue to perform the procedures, and the
procedures may be discontinued at any time. Neither we, the trustee nor any of
our or the trustee's agents will have any responsibility for the performance by
DTC or its respective participants, indirect participants or accountholders of
their respective obligations under the rules and procedures governing any of
their operations.

     The information in this section concerning DTC and its book-entry systems
has been obtained from sources that we believe to be reliable, but we take no
responsibility for its accuracy.

Exchange of the Global New Note for Certificated New Notes

     New notes issued or transferred to institutional "accredited investors"
within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the
Securities Act who are not QIBs will be issued in registered certificated form.
In addition, the global new note is exchangeable for definitive new notes in
registered certificated form if (1) DTC (x) notifies us that it is unwilling or
unable to continue as depository for the global new note and we thereupon fail
to appoint a successor depository or (y) has ceased to be a clearing agency
registered under the Exchange Act, (2) we, as our option, notify the trustee in
writing that we elect to cause the issuance of the new notes in certificated
form or (3) there shall have occurred and be continuing a Default or an Event of
Default concerning the notes. In all cases, certificated new notes delivered in
exchange for the global new note or beneficial interests in the global new note
will be registered in the names, and issued in any approved denominations,
requested by or on behalf of DTC (in accordance with its customary procedures).

          MATERIAL UNITED STATES AND CANADIAN INCOME TAX CONSIDERATIONS

     The discussion below is a general description of the material United States
and Canadian income tax consequences to beneficial owners of notes. This
discussion does not take into account the individual circumstances of any
particular investor and does not purport to discuss all of the possible tax
consequences of the purchase, ownership and disposition of the notes. Therefore,
prospective investors are urged to consult their own tax advisors concerning the
tax consequences of purchasing, holding and disposing of the notes, including
the application of state, provincial, local, foreign and other tax laws.

United States

     The following is a general discussion of the material U.S. federal income
tax consequences of the exchange of old notes for new notes under the exchange
offer and the ownership and disposition of the new notes to investors who are
U.S. Holders. As used in this prospectus, "U.S. Holder" means a beneficial owner
of a note that is

     o    an individual who is a citizen or resident of the United States,

     o    a corporation or other entity taxable as a corporation, created or
          organized in or under the laws of the United States or of any state of
          the United States (including the District of Columbia),

     o    an estate the income of which is includable in gross income for U.S.
          federal income tax purposes regardless of its source or

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

     This discussion is based on the Internal Revenue Code of 1986, as amended
or the Code, Treasury regulations promulgated under the Code, and administrative
and judicial interpretations of the Code, all as in effect or proposed on the
date of this prospectus and all of which are subject to change, possibly with
retroactive effect. This discussion is limited to U.S. Holders that purchase
notes at the issue price and hold notes as capital assets within the meaning of
Section 1221 of the Code. This discussion does not address federal alternative
minimum tax consequences or all aspects of U.S. federal income taxation that may
be relevant to particular purchasers in light of their personal circumstances or
to purchasers subject to special treatment under U.S. federal 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 notes as part of a "straddle," "hedge" or "conversion
transaction," persons that have a "functional currency" other than the U.S.
dollar and persons that own notes through partnerships or other pass-through
entities). This discussion also does not address any tax consequences arising
out of the tax laws of any state, local or foreign jurisdiction.

     Prospective purchasers are urged to consult their own tax advisors as to
the particular tax consequences to them of the exchange of old notes for new
notes and the ownership and disposition of new notes, including the
applicability of any state, local or foreign tax laws, and any changes (or
proposed changes) in applicable tax laws or their interpretations.



                                     -142-

Federal Income Tax Consequences of Tendering Old Notes for New Notes

     Exchange Offer

     A U.S. Holder will not recognize taxable gain or loss on the exchange of
old notes for new notes under the exchange offer, and a U.S. Holder's tax basis
and holding period for the new notes will be the same as for the old notes
immediately before the exchange.

Federal Income Tax Consequences of Owning and Disposing of New Notes

     Interest on Notes

     Interest paid on a note will be taxable to a U.S. Holder as ordinary
interest income, generally at the time it is received or accrued, in accordance
with the holder's regular method of accounting for United States federal income
tax purposes. If Canadian withholding taxes are imposed on the interest
payments, Worldwide Fiber will be required to pay Additional Amounts to holders
of notes (see "Description of Notes--Payment of Additional Amounts"). Worldwide
Fiber believes that the imposition of Canadian withholding taxes concerning
interest on the notes as a result of a change in Canadian tax law is a remote
and incidental contingency. Accordingly, Worldwide Fiber does not intend to
treat the notes as contingent payment debt instruments. Similarly, Worldwide
Fiber believes that the likelihood of a redemption or a repurchase as a result
of a "Change of Control" is remote and Worldwide Fiber does not intend to treat
that possibility as affecting the yield to maturity of the notes for U.S.
federal income tax purposes.

     Sale, Redemption or Retirement of Notes

     Upon the sale, redemption, retirement at maturity or other taxable
disposition of a note, a U.S. Holder generally will recognize gain or loss equal
to the difference between the sum of cash plus the fair market value of all
other property received on that sale, redemption, retirement or disposition
(except to the extent the cash or property is attributable to accrued but unpaid
interest that has not previously been included in the holder's income) and the
U.S. Holder's tax basis in the note (generally, its cost).

     Gain or loss recognized on the sale or other taxable disposition of a note
generally will be capital gain or loss and will be long-term capital gain or
loss if, at the time of the disposition, the note has been held for more than
one year. In the case of a U.S. Holder who is an individual, long term capital
gains generally are subject to a maximum capital gains rate of 20%.

     Foreign Tax Credit Considerations

     Interest on the notes will constitute income from sources without the
United States for United States foreign tax credit purposes. Payment of interest
on the notes will not be subject to Canadian withholding tax. See "--Canada."
If, however, the interest payments on the notes become subject to Canadian
withholding taxes as the result of a change in Canadian tax law, U.S. Holders
will be treated for U.S. federal income tax purposes as having actually received
the amount of the taxes withheld and as having paid that amount to the Canadian
taxing authorities. As a result, the amount of interest income included in gross
income by a U.S. Holder generally will be greater than the amount of cash
actually received by the U.S. Holder from Worldwide Fiber for the interest
income. A U.S. Holder may be able, subject to generally applicable limitations,
to claim a foreign tax credit or take a deduction for Canadian withholding taxes
imposed on interest payments (including withholding taxes imposed on Additional
Amounts).

     Gain or loss on the sale, redemption, retirement at maturity or other
taxable disposition of a note generally will constitute U.S. source gain or loss
for U.S. foreign tax credit purposes.



                                     -143-
<PAGE>

     Backup Withholding

     Backup withholding may apply to certain payments of principal, premium, if
any, and interest on a note and to proceeds of the sale or other disposition of
a note before maturity. Worldwide Fiber, or its U.S. agent or broker, will be
required to withhold from any payment that is subject to backup withholding a
tax equal to 31% of the payment, unless the U.S. Holder furnishes its taxpayer
identification number (social security or employer identification number),
certifies that the number is correct, certifies as to no loss of exemption from
backup withholding and otherwise complies with the applicable requirements of
the backup withholding rules. Certain U.S. Holders, including corporations, are
not subject to backup withholding. Any amounts withheld under the backup
withholding rules from a payment to a U.S. Holder generally will be allowed as a
credit against the U.S. Holder's U.S. federal income tax liability and may
entitle the U.S. Holder to a refund, provided that the required information is
furnished to the Internal Revenue Service.

Canada

     The following summarizes the material Canadian federal income tax
considerations as of the date of this prospectus under the Income Tax Act
(Canada) (the "Canadian Tax Act") and the published administrative practice of
Revenue Canada generally applicable to a holder of notes who acquires notes
under this prospectus.

     This summary is based upon the provisions of the Canadian Tax Act and the
regulations adopted under the Canadian Tax Act (the "Regulations") in force on
the date of this prospectus, proposed amendments to the Canadian Tax Act and the
Regulations publicly announced prior to the date of this prospectus by or on
behalf of the Minister of Finance (Canada) and current published administrative
practices and assessing policies of Revenue Canada. This summary does not
otherwise take into account or anticipate any changes in law or administrative
practice, whether by legislative, governmental or judicial action, nor does it
take into account provincial or foreign income tax considerations. This summary
of Canadian federal income tax considerations does not take into account the
individual circumstances of any particular investor and does not purport to
discuss all of the possible tax consequences of an investment in the notes.
Prospective holders should consult their tax advisors for advice regarding the
income tax considerations applicable to them.

     The following discussion is applicable to a holder (other than an initial
purchaser) who, for purposes of the Canadian Tax Act and any relevant tax
treaty, deals at arm's length with Worldwide Fiber, is not and is not deemed to
be a resident of Canada, does not use or hold, and is not deemed to use or hold,
the notes in the course of carrying on a business in Canada and, in the case of
a person who carries on an insurance business in Canada and elsewhere,
establishes the notes are not effectively connected with the insurance business
carried on in Canada and are not "designated insurance property" for purposes of
the Canadian Tax Act (a "Non-Resident Holder"). For purposes of the Canadian Tax
Act, related persons (as defined in the Canadian Tax Act) are deemed not to deal
at arm's length, and it is a question of fact whether persons not related to
each other deal at arm's length.

     The payment by Worldwide Fiber of interest, principal or premium on the
notes to a Non-Resident Holder will be exempt from Canadian withholding tax.

     No other tax on income (including taxable capital gains) will be payable by
a Non-Resident Holder under the Canadian Tax Act as a result of the acquisition,
holding, sale, redemption or other disposition of the notes, including the
receipt of interest or premium thereon.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives new notes for its own account through the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the new notes. This prospectus, as it



                                     -144-
<PAGE>

may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of new notes received in exchange for old notes where
the old notes were acquired by the broker-dealer as a result of market-making
activities or other trading activities. We have agreed that, starting on the
expiration date and ending on the close of business on the 180th day following
the expiration date, we will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with a resale.

     We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
through the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions through
the writing of options on the new notes or a combination of these methods of
resale, at market prices prevailing at the time of resale, at prices related to
prevailing market prices or at negotiated prices. The resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from the broker-dealer
and/or the purchasers of the new notes. Any broker-dealer that resells new notes
that were received by it for its own account under the exchange offer and any
broker or dealer that participates in a distribution of new notes may be
considered to be an "underwriter" within the meaning of the Act and any profit
of resale of new notes and any commissions or concessions received by any person
may be considered to be underwriting compensation under the Securities Act. The
letter of transmittal states that, by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not have admitted that it is an
"underwriter" within the meaning of the Securities Act. By acceptance of the
exchange offer, each broker-dealer that receives new notes under the exchange
offer agrees to notify us before using this prospectus in connection with the
sale or transfer of new notes, and acknowledges and agrees that, upon receipt of
notice from us of the happening of any event which makes any statement in this
prospectus untrue in any material respect or which requires the making of any
changes in this prospectus to make the statements in this prospectus not
misleading, which notice we agree to deliver promptly to the broker-dealer, the
broker-dealer will suspend use of this prospectus until we have amended or
supplemented the prospectus to correct the misstatement or omission and have
furnished copies of the amended or supplemented prospectus to the broker-dealer.

     For a period of 180 days after the expiration date, we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests these documents in the letter of
transmittal. We have agreed to pay all expenses for the exchange offer
(including the expenses of any one special counsel for the holders of the notes)
other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the notes participating in the exchange offer
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

     The holder of each old note accepted for exchange will receive a new note
in an amount equal to the surrendered old note. Old notes accepted for exchange
will not accrue interest from the date the exchange offer is completed. Holders
of old notes accepted for exchange will not receive any payment of accrued
interest on those old notes. Old notes which are not tendered or not accepted
for exchange will continue to accrue interest.

     The old notes were issued on July 28, 1999 in a transaction exempt from the
registration requirements of the Securities Act. They may not be offered or sold
in the United States unless registered or under an applicable exemption under
the Securities Act. We are offering the new notes under this prospectus to
satisfy certain of our obligations contained in the registration rights
agreement we entered into concerning the offering. Based on interpretations by
the staff of the Securities and Exchange Commission as described in no-action
letters issued to others, we believe that new notes issued through the exchange
offer in exchange for old notes may be offered for resale, resold and otherwise
transferred by any holder of notes, except a holder that is an affiliate of ours
within the meaning of Rule 405 under the Securities Act, without compliance with
the registration and prospectus delivery provisions of the Securities Act,
provided that these new notes are acquired in the ordinary course of the
holder's business and the holder has no arrangement or understanding with any
person to participate in a distribution of these new notes. However, we have not
sought a no-action letter concerning the exchange offer and we cannot assure you
that the staff of the Securities and Exchange Commission would make a



                                     -145-
<PAGE>

similar determination about the exchange offer. Each holder of old notes, other
than a broker-dealer, must acknowledge that it is not engaged in, and does not
intend to engage or participate in, a distribution of new notes and has no
arrangement or understanding to participate in a distribution of new notes. Each
broker-dealer that receives new notes for its own account through the exchange
offer must acknowledge that it will deliver a prospectus in connection with any
resale of new notes. The letter of transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not have admitted that it
is an "underwriter" within the meaning of the Securities Act. This prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer with resales of new notes received in exchange for old notes
acquired by that broker-dealer as a result of market-making activities or other
trading activities. We have agreed that, for a period ending at the close of
business on the 180th day following the expiration date, we will make this
prospectus available to any broker-dealer to use with resales. See "Plan of
Distribution."

     We will not receive any proceeds from the exchange offer. We will pay all
the expenses of the exchange offer. In the event we terminate the exchange offer
and do not accept any old notes for exchange we will promptly return the old
notes to the holders of the notes. See "The Exchange Offer."

     There has previously been only a limited secondary market, and no public
market, for the old notes. The old notes are eligible for trading in The Portal
Market. We have been advised by the initial purchasers that they intend to make
a market for the new notes; however, the initial purchasers are not obligated to
do so. We do not currently intend to list the new notes on any securities
exchange. Any market-making may be discontinued at any time, and there is no
assurance that an active public market for the new notes will develop or, if it
does develop, that it will continue. This prospectus may be used by the initial
purchasers in connection with offers and sales of the new notes which may be
made by them from time to time in market-making transactions at negotiated
prices relating to prevailing market prices at the time of sale. The initial
purchasers may act as principal or agent in this transaction.

     The exchange offer is not being made to, nor will we accept surrenders for
exchange from, holders of old notes in any jurisdiction in which the exchange
offer or the acceptance of it would not comply with the securities or blue sky
laws of that jurisdiction.

     You should rely only on the information contained in this document or what
we have referred you to. We have not authorized anyone to provide you with
information that is different.

     The market data included in this prospectus, including information relating
to our relative position in the industry, are based on independent industry
publications, other publicly available information or our management's good
faith beliefs. Although we believe that these independent sources are reliable,
the accuracy and completeness of these independent sources has not been
independently verified.

     Old notes in the aggregate principal amount of $500 million were issued
originally in global form. The global old note was deposited with The Depository
Trust Company, as initial depository. The global old note is registered in the
name of Cede & Co., as nominee of the depository. Beneficial interests in the
global old note are shown on, and transfers of the global old note are effected
only through, records maintained by the depository and its participants. The use
of the global old note to represent certain of the old notes permits the
depository's participants, and anyone holding a beneficial interest in an old
note registered in the name of that a participant, to transfer interests in the
old notes electronically in accordance with the depository's established
procedures without the need to transfer a physical certificate. The new notes
will also be issued initially as a note in global form and deposited with the
depository.

           ENFORCEABILITY OF CIVIL LIABILITIES AGAINST FOREIGN PERSONS

     We are a corporation organized under the laws of 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.

                              CURRENCY TRANSLATION

     We report our financial statements in U.S. dollars, while the currency of
measurement for our operations varies depending upon location. Unless otherwise
indicated, references to "dollars" or "$" are to U.S. dollars and references to
"Cdn. $" are to Canadian dollars.

     The following table lists, for each period indicated, the high and low
exchange rates for Canadian dollars expressed in U.S. dollars, based on the

Asynchronous Transfer Mode
<S>                                 <C>
(ATM).........................      A cell-based connection-oriented technology that provides a protocol for
                                    transmitting multiple traffic types over high-speed networks.

Available Bit Rate (ABR)......      A class of service in which the ATM Network makes its "best effort" to meet
                                    traffic bit rate requirements.

Band..........................      A range of frequencies between two defined limits

bandwidth.....................      The relative range of analog frequencies or digital signals that can be
                                    passed through a transmission medium, such as glass fibers, without
                                    distortion.  The greater the bandwidth, the greater the information carrying
                                    capacity.  Bandwidth is measured in hertz (analog) or bits per second
                                    (digital).

Bit...........................      A binary unit of information that can have either of two values, 0 or 1.

carrier's carrier.............      A provider of communications transmission services that specializes in the
                                    wholesale provision of telecommunications bandwidth and services to other
                                    carriers and service providers.

Cell..........................      For ATM, an information package consisting of 53 bytes, or octets, of data.
                                    Of these, the first 5 constitute the header: 48 carry the payload.

Cell Relay....................      Network transmission format that uses small packets of the same size, called
                                    cells.  The cells are fixed-length and can be transmitted and processed by
                                    hardware at very high rates.  Cell relay acts as a basis for ATM.

Cell Relay Service............      A carrier service that supports the receipt and transmission of ATM cells
                                    between end users in compliance with ATM standards and implementation
                                    specifications.

Circuit Emulation Service
(CES).........................      ATM Forum-defined service that provides a virtual circuit connection that
                                    emulates the characteristics of a real, constant-bit-rate,
                                    dedicated-bandwidth circuit.

city ring.....................      A facility of conduit and fiber optic cable encircling a metropolitan area.

Constant Bite Rate (CBR)......      Delay intensive applications such as video and voice that must be digitized
                                    and represented by a continuous bit stream.  CBR traffic requires guaranteed
                                    levels of service and throughput.

CRTC..........................      Canadian Radio-television and Telecommunications Commission.

customer premises equipment
edge..........................      ATM access equipment located on a customer site.

dark fiber....................      Fiber that lacks the requisite optical transmission equipment necessary to
                                    use the fiber for transmission.

digital.......................      Describes a method of storing, processing and transmitting information
                                    through the use of distinct electronic or optical pulses that represent the
                                    binary digits 0 and 1.  Digital transmission/switching technologies employ a
                                    sequence of discrete, distinct pulses to represent information, as opposed
                                    to the continuously variable analog signal.  This gives operators
                                    significant capacity increases over analog.

DWDM..........................      Dense Wavelength Division Multiplexing.  High speed version of WDM, which is
                                    a means of increasing the capacity of SONET fiber-optic transmission systems
                                    through the multiplexing of multiple wavelengths of light.  A technique for
                                    transmitting more than one light wave frequency on a single fiber to
                                    increase the information carrying capacity.

                                    strands in order to transmit digital information.  Fiber optic cable is the
                                    medium of choice for the telecommunications and cable industries.

frame relay...................      A high-speed, data-packet switching service used to transmit data between
                                    computers.  Frame Relay supports data units of variable lengths at access
                                    speeds ranging from 56 kilobits per second to 1.5 megabits per seconds.
                                    This service is well-suited for connecting local area networks, but is not
                                    presently well suited for voice and video applications due to the variable
                                    delays which can occur.  Frame Relay was designed to operate at high speeds
                                    on modern fiber optic networks.

                                    devices on a network exchange information.  These rules consist of syntax
                                    (header structure), semantics (actions and reactions that are supposed to
                                    occur), and timing (relative ordering and direction of states and events).

Quality of Service (QoS)......      The set of parameters and their values that quantify the performance of a
                                    given virtual circuit.

RBOC..........................      Regional Bell Operating Companies.  The seven local telephone companies
                                    established as a result of the court-ordered breakup in 1984 of AT&T.

Regeneration Shelter..........      A self-contained, pre-constructed building that houses environmental and
                                    electrical support for optoelectric circuitry.

reseller......................      A carrier that does not own transmission facilities, but obtains
                                    communications services from another carrier on a wholesale basis for resale
                                    to the public.

route miles...................      The number of miles of the telecommunications path in which fiber optic
                                    cables are installed.

ROW...........................      Rights-of-way, licenses and permits (creating a contractual interest and not
                                    an interest in land) from third party landowners and governmental
                                    authorities which permit the holder to install conduit and fiber.

SONET Ring....................      Synchronous Optical Network Technology Ring.  An electronics and network
                                    architecture for variable-bandwidth products which enables transmission of
                                    voice, data and video (multimedia) at very high speeds in the event of a
                                    fiber cut by automatically rerouting traffic in the opposite direction
                                    around the ring.

switch........................      A sophisticated computer that accepts instructions from a caller in the form
                                    of a telephone number.  Like an address on an envelope, the numbers tell the
                                    switch where to route the call.  The switch opens or closes circuits or
                                    selects the paths or circuits to be used for transmission of information.
                                    Switching is a process of interconnecting circuits to form a transmission
                                    path between users.  Switches allow local telecommunications service
                                    providers to connect calls directly to their destination, while providing
                                    advanced features and recording connection information for future billing.

Switched Virtual Circuit
(SVC).........................      A virtual link, with variable end-points, established through an ATM network. With an
                                    SVC, the user defines the end-points when the call is initiated that are subsequently
                                    terminated at the end of the call.

Synchronous Optical Network
(SONET).......................      A Consultative Committee for International Telegraph and Telephony standard
                                    for synchronous transmission up to multi-gigabit speeds.

Unspecified Bit Rate (UBR)....      An ATM service type in which the ATM network makes a "best effort" to meet the
                                    transmitter's bandwidth requirements; essentially a "send and pray" service like
                                    that available from today's networks.

User Network Interface (UNI)..      The protocol to define connections between ATM end-stations and the ATM switch
                                    including signaling, cell structure, addressing, traffic management, and

Variable Bit Rate (VBR).......      Applications, which produce traffic of varying bit rates, like common LAN
                                    applications, that produce varying throughput rates.

Variable Bit Rate/non-real
time (VBR/nrt)................      One of five ATM Forum-defined service types.  Supports variable bit rate
                                    traffic which requires strict timing control, such as packetized voice or
                                    video, with average, and peak traffic parameters.

Variable Bit Rate/real time
(VBR/rt)......................      One of five ATM Forum-defined service types.  Supports variable bit rate
                                    traffic which requires strict timing control, such as packetized voice or
                                    video, with average, and peak traffic parameters.

Virtual Channel Connection
(VCC).........................      Virtual channels in two or more sequential physical circuits can be
                                    concatenated to create an end-to-end connection called a VCC.  A VCC is a
                                    specific instance of a SVC or PVC.  A VCC may traverse one end-to-end VPC or
                                    several sequential VPCs.

Virtual Circuit (VC)..........      Logical channel established as a result of the call initiation procedure to
                                    a network address that exists for a period of time.

Virtual Path..................      A group of virtual channels, which can support multiple virtual circuits.

Virtual Path
Identifier/Virtual Channel
Identifier (VPI/VCI)..........      Combined, these fields identify a connection in the ATM network.

xDSL..........................      A term referring to a variety of new Digital Subscriber Line technologies.
                                    Some of these varieties are asymmetric with
                                    different data rates in the downstream and
                                    upstream directions. Others are symmetric.
                                    Downstream speeds range from 384 kbps, or
                                    SDSL, to 1.5-8 Mbps, or ADSL.

              Nature and Purpose of Pro Forma Financial Information

                                   (Unaudited)

         The  accompanying  pro forma  consolidated  balance  sheet of Worldwide
Fiber  Inc.  (the   "Company")  as  at  June  30,  1999  assumes  the  following
transactions occurred on June 30, 1999: (i) the issuance on July 28, 1999 of the
$500,000,000  12% senior  notes ("the  Notes"),  (ii) the issuance on August 31,
1999 of 150,000 Class B Subordinate  Voting Shares for $3,000,000 of cash, (iii)
the  reorganization  of share  capital  of the  Company  on  September  9,  1999
including stock dividend of 5,000,000  Series C Redeemable  Preferred Shares and
redemption of 45,000,000 Series C Redeemable Preferred Shares for $45,000,000 of
cash (iv) the issuance on  September  9, 1999 of  8,866,808  Series A Non-Voting
Preferred  Shares for  $345,000,000 of cash and (v) the acquisition on September

network assets in exchange for 4,500,000  Class C Multiple  Voting Shares of the
Company.

         The accompanying pro forma consolidated income statement of the Company
for the six month  period  ended  June 30,  1999  gives  effect to the  interest
expense,  including  amortization of deferred  financing costs,  relating to the
Notes assuming the Notes were issued on January 1, 1998.

         The accompanying pro forma consolidated income statement of the Company
for the year ended  December 31, 1998 assumes  that the  following  transactions
occurred on January 1, 1998:  (i) the transfer on May 31, 1998 of certain of the
operations  of the  Telecommunications  Division  ("Division")  of  Ledcor,  the
Construction  Services,  Management  Services and Employee  Services  Agreements
between  the  Company  and  affiliates  of  Ledcor,  (ii) the  consolidation  of
Worldwide Fiber (USA), Inc. ("WFI USA"),  (formerly Pacific Fiber Link, Inc.) as
a result of the Company's agreement to increase its interest in WFI USA from 50%

including  amortization of deferred  financing costs,  relating to the Notes and
$175,000,000 12 1/2% senior notes (the "1998 Notes").

         The unaudited pro forma consolidated balance sheet and income statement
as of and for the  six  month  period  ended  June  30,  1999  is  based  on the
historical unaudited  consolidated financial statements for the six month period
ended June 30, 1999.

         The  unaudited  pro forma  consolidated  income  statement for the year
ended  December  31,  1998 is  presented  on the basis of the fiscal year end of
December  31,  1998  adopted  by the  Company  and is  based  on the  historical
consolidated  income  statement of the Company for the seven-month  period ended
December 31, 1998,  and the operations of the Division for the five months ended
May 31,  1998  derived  from the  historical  statement  of  operations  for the
Division for the nine months ended May 31, 1998.

         The  unaudited  pro forma  consolidated  financial  statements  are not
necessarily  indicative of the results that actually would have been achieved if
the transactions  reflected therein had been completed on the dates indicated or
the  results  which may be  obtained  in the  future.  The  unaudited  pro forma

            (tabular amounts expressed in thousands of U.S. dollars)


1.   Pro forma transactions

     The unaudited pro forma consolidated balance sheet and income statements of
the Company have been prepared to reflect the effects of the following completed
or proposed transactions.

     Effective May 31, 1998, the operations of the  Telecommunications  Division
("Division")  of Ledcor  Industries  Ltd.  ("Ledcor")  were  transferred  to the
Company. The transfer was pursuant to a series of agreements as follows:

     o    The Company obtained certain equipment, fiber optic network assets and
          other assets;

     o    Ledcor retained all construction  contracts  entered into prior to the
          transfer of the business and entered  into two  Construction  Services
          Agreements  whereby the Company  would  provide  services to Ledcor to
          complete the contracts in exchange for a fee;

     o    The Company and Ledcor  entered into a Management  Services  Agreement
          whereby  Ledcor  would  provide the  Company  with  management  staff,
          administrative  and other  support  services.  The Company  reimburses
          Ledcor for direct  costs  paid on the  Company's  behalf and pays Cdn.
          $200,000 per month for the Company's share of corporate overhead;

     o    The Company  and Ledcor  entered  into  Employee  Services  Agreements
          whereby  Ledcor   provides   personnel  for  designing,   engineering,
          construction and installation  services on a cost reimbursement  basis
          to the Company;

     o    The Company and Ledcor entered into an undertaking whereby the Company
          would   provide   services  to  complete  the  Canadian   Fiber  Optic
          Transmission  System and,  upon  completion,  a portion of the network
          would be  transferred  from Ledcor to the  Company in  exchange  for a
          fixed  number of common  shares of the  Company  as  described  in the
          following point;

     o    As described in Note 1 to the consolidated financial statements of the
          Company,  on March 31, 1999,  the Company  issued  19,999,700  Class A
          common shares to its parent Ledcor in exchange for certain fiber optic
          assets.  A pro forma balance  sheet has not been  presented to reflect
          the effect of this transaction on the historical  consolidated balance
          sheet of the Company as of December  31,  1998.  The  transaction  was
          accounted  for as a  transaction  between a parent and a wholly  owned
          subsidiary and accordingly,  fixed assets acquired by the Company were
          recorded  at the  carrying  amount of the  assets in the  accounts  of
          Ledcor. If this transaction had occurred at December 31, 1998,

                                   (Unaudited)

                  For the six month period ended June 30, 1999
                      and the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     o    the fixed assets would have increased by $21,883,000,  the cost of the
          assets in the  accounts of Ledcor as at December  31,  1998,  deferred
          income  taxes  would have  increased  by  $3,136,000  as a result of a
          higher tax cost versus  accounting cost of fixed assets and the stated
          amount  of  the  Company's   common  stock  would  have  increased  by
          $25,019,000;

     These agreements are summarized in the consolidated financial statements of
the Company for the period ended December 31, 1998.

     As described in the notes to the unaudited interim  consolidated  financial
statements for the six month period ended June 30, 1999 and audited consolidated
financial statements for the period ended December 31, 1998, the Company entered
into a series of  agreements  with  affiliates  of Ledcor  whereby  the  Company
acquired  certain fiber optic network assets.  Closing occurred on September 27,
1999. As consideration, upon closing, the Company issued to affiliates of Ledcor
4,500,000 Class C Multiple Voting Shares.  In addition,  the Company has assumed
certain rights and  obligations of the affiliates  under their 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.

     On December 23, 1998, the Company issued $175,000,000  12-1/2% Senior notes
due  2005  (the  "1998  Notes")  and  on  July  28,  1999,  the  Company  issued
$500,000,000 12% Senior notes due 2009 (the "Notes").

     On December 31, 1998, the Company increased its interest in Worldwide Fiber
(USA),  Inc. ("WFI USA") (formerly  Pacific Fiber Link, Inc.) from 50% to 75% in
exchange for the conversion of a note amounting to $3,915,000.

     Pursuant to a reorganization  of the Company's share capital,  on September
9, 1999,  the Company  amended its share  capital by  redesignating  all Class A
Voting Shares to Class B Subordinate  Voting  Shares,  cancelling  the remaining
classes of shares  and  creating  Class A  Non-Voting  shares,  Class C Multiple
Voting  shares,  Series  A and B  Preferred  Shares,  and  Series  C  Redeemable
Preferred Shares.

     On August 31, 1999, the Company  issued 150,000 Class B Subordinate  Voting
Shares (redesignated from Class A Voting Shares) for $3,000,000 of cash.

     Subsequently,  the Company  declared a stock dividend of 5,000,000 Series C
Redeemable   Preferred  Shares.   Concurrently,   the  Company  repurchased  the
25,000,000  outstanding  Class B  Subordinate  Voting  Shares from its parent in
exchange for the issuance of 23,043,500  Class

2.   Basis of presentation

     The unaudited pro forma balance sheet and  consolidated  income  statements
have  been  prepared  by  management  in  accordance  with  generally   accepted
accounting  principles  in the United States and the pro forma  assumptions  and
adjustments described in notes 1, 4, 5 and 6.

     The unaudited pro forma consolidated  balance sheet and income statement as
of and for the six month  period  ended June 30, 1999 is based on the  unaudited
historical  consolidated  financial  statements of the Company for the six month
period ended June 30, 1999.

     The unaudited pro forma  consolidated  income  statement for the year ended
December  31, 1998 is  presented on the basis of the fiscal year end of December
31 adopted by the Company.  The pro forma consolidated  income statement for the
year ended  December  31, 1998 is based on the  historical  consolidated  income
statement of the Company for the seven-month period ended December 31, 1998, and
the  operations  of the  Division for the five months ended May 31, 1998 derived
from the historical statement of operations for the Division for the nine months
ended May 31, 1998.

     The  unaudited  pro  forma  consolidated   financial   statements  are  not
necessarily  indicative of the results that actually  would have resulted if the
transactions  reflected  herein had been completed on the dates indicated or the
results  which  may  be  obtained  in  the  future.   The  unaudited  pro  forma
consolidated   financial   statements   should  be  read  in  conjunction   with
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations and the consolidated  financial statements of the Company,  financial
statements  of the  Division,  and  consolidated  income  statement  of WFI USA,

                                   (Unaudited)

                  For the six month period ended June 30, 1999
                      and the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     4.   Pro forma consolidated balance sheet assumptions and adjustments as at
          June 30, 1999

     The following  assumptions and adjustments  have been made in the pro forma
consolidated balance sheet as at June 30, 1999.

          (i)  Notes

         This adjustment records the Notes assuming they had been issued on June
30, 1999.

          (ii) Acquisition of fiber optic network assets

         This adjustment records the acquisition by the Company of certain fiber
optic  network  assets from Ledcor in exchange  for  4,500,000  Class C Multiple
Voting shares in  accordance  with the May 28, 1999 and September 27, 1999 share
purchase  agreements.  This  transaction  closed on September  27, 1999. If this
transaction had occurred at June 30, 1999 management estimates that fixed assets
would have increased by approximately $26,000,000, the cost of the assets in the
accounts of Ledcor,  deferred income taxes would have increased by approximately
$12,000,000,  as a result of a higher tax cost versus  accounting  cost of fixed
assets, accounts payable would have increased by approximately $30,000,000,  the
liability  recorded  in the  accounts  of Ledcor,  and the stated  amount of the
Company's common stock would have increased by approximately $8,000,000.

          (iii) Share reorganization

          This  adjustment  records  the stock  dividend of  5,000,000  Series C
Redeemable  Preferred  Shares with an  estimated  fair value of  $5,000,000  and
subsequent  redemption of 45,000,000  Series C Redeemable  Preferred  Shares for
$45,000,000 of cash.

          (iv) Issuance of Series A Non-Voting Preferred Shares

         This adjustment  records the issuance of 8,866,808  Series A Non-Voting
Preferred Shares for $345,000,000 of cash.

          (v)  Issuance of Class B subordinate voting shares

         This  adjustment  records the issuance of 150,000  Class B  Subordinate
Voting Shares (redesignated from Class A Voting Shares) for $3,000,000 of cash.

          (vi) Capital taxes

                                   (Unaudited)

                  For the six month period ended June 30, 1999
                      and the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     This adjustment  records  estimated  additional BC Corporation  Capital and
Federal Large  Corporation  taxes payable of $2,200,000 for the six month period
ended  June 30,  1999  resulting  from the  issuance  of the Notes and  Series A
Non-Voting preferred shares.

5.   Pro Forma Consolidated Income Statement assumptions and adjustments for the
     six month period ended June 30, 1999

     The following  assumptions and adjustments  have been made in the pro forma
consolidated  income statement to reflect the effect of the additional  interest
expense,  including  amortization of deferred  financing  costs,  related to the
Notes.

     (i)  Interest expense

     This adjustment  records the interest  expense,  including  amortization of
deferred financing costs, related to the Notes assuming the Notes were issued on
January 1, 1998. Amortization of the deferred financing costs was computed based
on the effective  interest method.  The Company would have capitalized a portion
of interest  expense related to the Notes to the cost of the fiber optic network
assets constructed during the six month period ended June 30, 1999, which is not
reflected in this pro forma statement.

     (ii) Income taxes

     This  adjustment  records an income tax recovery of $2,524,000  for the six
month period ended June 30, 1999 using an effective tax rate of 41.1%.

     (iii) Capital taxes

     This adjustment records estimated  additional BC Corporation  Capital taxes
of $1,250,000 and Federal Large  Corporation taxes of $950,000 for the six month
period ended June 30, 1999 resulting from the issuance of the Notes and Series A
Non-Voting Preferred Shares.

6.   Pro forma consolidated income statement assumptions and adjustments for the
     year ended December 31, 1998

     Pursuant  to the  transactions  with  Ledcor,  the  Company has not assumed
certain  construction  contracts  that are the  responsibility  of  Ledcor.  The
Company  provides   construction  services  to  Ledcor  for  such  contracts  in
accordance with the Construction Services Agreements.  In addition,  the Company
reimburses  Ledcor for  general and  administrative,  and other  costs,  paid by
Ledcor on the Company's  behalf,  in accordance with the Management and Employee
Services Agreements.

                    Notes to Pro Forma Financial Information

                                   (Unaudited)

                  For the six month period ended June 30, 1999
                      and the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     The following  assumptions and adjustments  have been made in the pro forma
consolidated  income  statement for the year ended  December 31, 1998 to reflect
the  retention  of various  contracts  by Ledcor,  the  provision of general and
administrative  services,  the  consolidation  of  WFI  USA  in  respect  of the
acquisition of an additional interest in WFI USA bringing the Company's interest
to 75% on December 31, 1998, and the effect of the additional  interest expense,
including  amortization of deferred  financing  costs,  related to the Notes and
1998 Notes.

     (i)  Revenue and costs

     Under the  Construction  Services  Agreements  with Ledcor,  the Company is
reimbursed  for all costs  incurred plus a fee of 15%.  Contract costs have been
adjusted  to  reflect  costs  incurred  by the  Division  that are  included  in
inventory  which  would  have  been  reimbursed  if  the  Construction  Services
Agreements  had been in place.  Revenues have been adjusted to reflect the costs
incurred plus the 15% fee for the five-month period ended May 31, 1998.

     (ii) General and administrative costs

     In accordance with the Management Services  Agreement,  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.

     This adjustment  eliminates the general corporate  overhead costs allocated
to the  Division  of  $299,546  and  records  $693,575  in  accordance  with the
Management Services Agreement for the five-month period ended May 31, 1998.

     (iii) Interest expense

     This adjustment  records the interest  expense,  including  amortization of
deferred  financing costs,  related to the Notes and the 1998 Notes assuming the
Notes and the 1998 Notes were  issued on  January 1, 1998.  Amortization  of the
deferred  financing  costs was computed  based on the  effective  interest  rate
method.  The Company would have  capitalized  a portion of the interest  expense
related  to the Notes  and 1998  Notes to the cost of the  fiber  optic  network
assets  constructed  during  the year  ended  December  31,  1998,  which is not
reflected in this pro forma income statement.

     (iv) Income taxes

     This adjustment  records an income tax recovery of $27,593,000 for the year
ended  December  31, 1998 using an  effective  tax rate of 41.1%  related to the
recognition of a deferred tax asset from the tax loss  carryforward  created for
the year ended December 31, 1998. Management believes that,

                    Notes to Pro Forma Financial Information

                                   (Unaudited)

                  For the six month period ended June 30, 1999
                      and the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)


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 $2,500,000 and Federal Large Corporation tax of $1,900,000 for the year ended
December  31,  1998  resulting  from the  issuance  of the  Notes  and  Series A
Non-Voting preferred shares.

     (vi) Acquisition of additional interest in WFI USA

     It has been assumed that the Company's  acquisition  of the  additional 25%
interest in WFI USA occurred on February 11,  1998,  the date WFI USA  commenced
operations.

     Depreciation  expense  has not been  adjusted  for the  acquisition  of the
additional interest in WFI USA as the fiber optic network assets of WFI USA were
under construction at the date of acquisition and are not yet available for use.
Accordingly,  if  the  acquisition  had  occurred  on  February  11,  1998,  the
transaction  would have been  reflected  as an issuance  of shares for cash.  No
interest income has been recognized on this transaction.

     This adjustment eliminates the Company's equity in the earnings of WFI USA,
records the net income  attributed  to the minority  interest as a result of the
consolidation of the net income of WFI USA, and eliminates intercompany interest
charged.

1.   The Company

     Worldwide   Fiber  Inc.  (the   "Company")  is  indirectly  a  wholly-owned
subsidiary  of  Ledcor  Inc.  (Ledcor).  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.

     These  financial   statements  should  be  read  in  conjunction  with  the
consolidated  financial  statements of the Company for the period ended December
31, 1998.

Transactions with Ledcor

     On March 31, 1999 the Company  completed a series of  transactions  whereby
certain fiber optic network assets were  transferred to the Company by Ledcor in
exchange for 19,999,700  Class A common shares.  The cost of the assets acquired
at March 31, 1999 amounted to $21,884,000.  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.

Basis of Presentation

     These  unaudited  interim  consolidated  financial  statements  reflect all
adjustments  which  are,  in the  opinion  of  management,  necessary  to a fair
statement  of the  results  for the interim  periods  presented  and include all
adjustments of a normal recurring nature.

Significant accounting policies

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

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

Company  prior to August 1, 2002 with the net proceeds from certain sales of the
Company's common stock.

     The 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.

     The  interest  rate on the Notes is subject to increase if the Company does
not file a registration  statement  with the Securities and Exchange  Commission
within certain time periods specified in the Notes Indenture.

     Agreement with Ledcor

     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,  upon closing,  the
Company issued to affiliates of Ledcor 4,500,000 Class C Multiple Voting shares.
In  addition,  the  Company  assumed  certain  rights  and  obligations  of  the
affiliates under their 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.  Management
estimates  that  based on  information  available  to date,  fixed  assets  will
increase by approximately $26,000,000, the cost of the assets in the accounts of
Ledcor, deferred income taxes will increase by approximately  $12,000,000,  as a
result of a higher tax cost versus  accounting  cost of fixed  assets,  accounts
payable will increase by approximately  $30,000,000,  the liability  recorded in
the accounts of Ledcor, and the stated amount of the Company's common stock will
increase by approximately $8,000,000.

     Share Reorganization

     Pursuant to a reorganization  of the Company's share capital,  on September
9, 1999,  the Company  amended its share  capital by  redesignating  all Class A
Voting Shares to Class B Subordinate  Voting  Shares,  cancelling  the remaining
classes of shares  and  creating  Class A  Non-Voting  Shares,  Class C Multiple
Voting  Shares,  Series  A and B  Preferred  Shares,  and  Series  C  Redeemable
Preferred  Shares.  Subsequently,  the  Company  declared  a stock  dividend  of
5,000,000  Series C  Redeemable  Preferred  Shares.  Concurrently,  the  Company
repurchased the 25,000,000  outstanding  Class B Subordinate  Voting Shares from
its parent in exchange for the issuance of 23,043,500 Class B Subordinate Voting
Shares and 40,000,000  Series C Redeemable  Preferred  Shares.  The Company then
redeemed the 45,000,000  outstanding  Series C Redeemable  Preferred  Shares for
$45,000,000 of cash.

                                AUDITORS' REPORT

To the Directors and Shareholder of
Worldwide Fiber Inc.

         We have audited the consolidated  balance sheet of Worldwide Fiber Inc.
as at December 31, 1998 and the consolidated  income statement and statements of
changes in  shareholder's  equity and cash flows 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 audit.

         We conducted our audit 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 consolidated financial statements present fairly,
in all material  respects,  the financial position of the Company as at December
31,  1998 and the  results of its  operations  and its cash flows 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.

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

1.   The Company

     Worldwide Fiber Inc. (the  "Company") was  incorporated on February 5, 1998
and is indirectly a  wholly-owned  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  to  December  31,  1998,
$162,455,000  of  the  Company's  revenues  related  to  Construction   Services
Agreements with Ledcor (see Note 1(ii)).

     Transactions with Ledcor

     On May 31, 1998, the Company entered into several agreements with Ledcor as
follows:

          (i) Undertaking  agreement whereby certain fiber optic network assets,
     located  in Canada  and the U.S.  would be  transferred  to the  Company by
     Ledcor in  exchange  for  19,999,700  Class A common  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  will be 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 fixed  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 will be reflected as a
     deferred tax asset.

          (ii) Construction Services Agreements 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  these  consolidated  financial  statements.   The  costs  to
     construct the network will be reflected when the  construction is completed
     and the shares have been issued.  As at December 31, 1998,  the Company has
     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

            (tabular amounts expressed in thousands of U.S. dollars)

     $945,000,  has been excluded from the consolidated income statement and has
     been reported as contributed surplus.

          (iii)  Management  Services  Agreement  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.  In accordance with
     this  agreement,  substantially  all costs  and  expenses  incurred  by the
     Company  were  paid  by  Ledcor  and  charged  to the  Company  through  an
     intercompany account.

          (iv)  Employee  Services  Agreements  whereby the Company  obtains the
     services of certain employees from Ledcor on a cost reimbursement basis.

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% interest
in  Worldwide  Fiber  (USA),  Inc.  ("WFI USA").  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  consolidated  income  statement  and statement of cash
flows account 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  sheet  includes  WFI USA's  assets and  liabilities,  and
minority interest therein, as at December 31, 1998.

     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.

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     Fixed assets

     Fiber  optic  network  assets  constructed  for the  Company's  own use are
recorded as fixed assets. Fiber optic network assets, construction equipment and
other  assets are  recorded  at cost.  Fixed  assets are  depreciated  using the
following rates and methods:

     o    Fiber optic  network  assets--straight-line  method over the estimated
          useful lives of the assets.

     o    Construction  equipment--hourly  usage rates,  estimated to depreciate
          the equipment over the estimated useful lives of the equipment.

     o    Other assets--straight-line method, over the estimated useful lives of
          the assets.

     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").

     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.

     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.

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     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 for the period ended December 31, 1998 was $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.

     Advances on contracts

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

     Foreign currency transactions

     The Company's  functional currency is the Canadian dollar. The consolidated
financial   statements  are  translated  to  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 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 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.

     Fair value of financial instruments

     The fair value of the Company's financial  instruments,  consisting of cash
and cash equivalents,  accounts receivable,  unbilled revenue, deposit, due from
parent,  accounts  payable,  advances on  contracts,  and income  taxes  payable
approximate  their carrying values due to their  short-term  nature.  The Senior

notes  were  issued at  period  end and  accordingly  fair  value  does not vary
significantly from carrying value at December 31, 1998.

     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.

     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
were  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

change  in the tax  basis of the U.S.  assets  with  the  adjustment  being
reflected as contributed  surplus.  As consideration  for the  transaction,  the
Company issued 200 Class A shares to Ledcor.

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

         Assets

              Construction equipment..................................... $2,830

     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  2,000,000  Class A common  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 3,000,000  Class A
common  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 Division of Ledcor.

            (tabular amounts expressed in thousands of U.S. dollars)

     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:

         Current assets...........................................       $3,742
         Inventory................................................        6,048
         Fixed assets.............................................        1,795
         Current liabilities......................................       10,052

     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:

     o    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.

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

     o    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.

     The  amounts  due  from  Ledcor  and  advances  received  from  Ledcor  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 due to fiber optic network assets
to be transferred to the Company as described in note 1(ii).

7.   Senior notes

     The Senior notes (the  "Notes") are  unsecured  obligations  of the Company
bearing interest at 12.5% payable semi-annually.  The 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 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 Notes Indenture,  the holders of the Notes can
require  the  Company  to  repurchase  all or part of the  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 Notes
Indenture,  exceeds  $10,000,000,  the  Company is  required to make an offer to
repurchase the maximum  principal amounts of 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  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  contain  certain  covenants  that  restrict  the  ability of the
Company and its subsidiaries to incur additional  indebtedness and issue certain
preferred stock, pay dividends or make other  distributions,

repurchase  equity  interests or subordinated  indebtedness,  engage in sale and
leaseback  transactions,  create certain liens, enter into certain  transactions
with 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.

     The  interest  rate on the Notes is subject to increase if the Company does
not file a registration  statement  with the Securities and Exchange  Commission
within certain time periods specified in the Notes Indenture.

8.   Preferred stock

     Authorized

     The Company is authorized  to issue an unlimited  number of Class I, II and
III preferred shares (collectively "preferred shares"). As at December 31, 1998,
there were no issued and outstanding preferred shares.

     Voting

     The holders of Class I preferred shares are entitled to attend  shareholder
meetings  and to one vote for each share  held.  The holders of Class II and III
preferred shares are not entitled to vote or attend shareholder meetings.

     Dividends

     The holders of  preferred  shares are  entitled to receive a dividend  when
declared  by the Board of  Directors.  The holders of  preferred  shares have no
preference or priority as to the declaration of dividends,  and dividends may be
declared  and paid on any other class of shares of the Company to the  exclusion
of a dividend being declared and paid on the preferred shares.  Dividends may be
declared and paid on the  preferred  shares  individually  to the exclusion of a
dividend  being  declared  and paid on another  class of  preferred  shares.  No
dividends  can be declared on such other shares if it impairs the ability of the
Company to redeem the outstanding preferred shares.

     Return of capital

     In the event the Company is liquidated,  dissolved or wound up, the holders
of preferred  shares have priority as to payment of the redemption price and for
all declared and unpaid dividends over all other shares.

     Redemption and retraction

     The Company  may redeem or  purchase  preferred  shares  together  with all
declared and unpaid dividends.  In addition, the holders of preferred shares are
entitled to have the Company redeem or purchase all or any part of the preferred
shares held by a shareholder.

9.   Common stock

     Authorized

     The Company is authorized to issue an unlimited  number of Class A, B and C
common shares (collectively "common shares").

     Voting

     The  holders of Class A and B common  shares are  entitled  to one vote for
each share held. The holders of Class C common shares are not entitled to vote.

     Dividends

     The  holders of common  shares  are  entitled  to  receive a dividend  when
declared by the directors of the Company.  Dividends may be declared and paid on
the common shares without  declaring  dividends on any other class or classes of
shares of the  Company.  However,  no  dividends  can be  declared on the common
shares if to do so would  impair  the  ability  of the  Company  to  redeem  any
outstanding preferred shares.

     Return of capital

     In the  event  the  Company  is  liquidated,  dissolved  or wound up or the
Company distributes the assets of the Company among shareholders for the purpose
of winding up its  affairs,  the holders of common  shares rank equally with one
another to receive  any  remaining  balance of the assets of the  Company  after
payment for a return of capital and any  declared  but unpaid  dividends  to the
holders of preferred shares.

10.  Income taxes

     Income before equity income and income taxes.

         The  components  of income before equity income and income taxes are as
follows:

         Canadian....................................................   $5,683
         U.S.........................................................    8,052
                                                                     =========
                                                                       $13,735
                                                                     =========



         Current income taxes

         The provision for current income taxes consists of the following:

         Canadian....................................................   $2,599
         U.S. federal................................................    2,563
         U.S. state and local........................................      481
                                                                     ---------
                                                                        $5,643
                                                                     =========

     The Company's  statutory  rate of 45.6% varies from its  effective  rate of
41.1% due primarily to federal and state taxes on U.S. income at a rate of 38%.

     Deferred income taxes

     Significant components of the Company's deferred tax assets and liabilities
are as follows:

         Fixed assets (note 5)......................................    $1,088
         Other......................................................       185
         Valuation allowance........................................        --
         Net deferred tax assets....................................    $1,273
                                                                        ======


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

            (tabular amounts expressed in thousands of U.S. dollars)

11.  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,  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  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 twelve customers  accounted for the entire accounts receivable and unbilled
revenue balances.

     The concentration of credit risk relating to the amount due from the parent
is  considered  limited due to the credit  quality of the Company's  parent.  As
described in Note 1,  substantially  all of the  Company's  revenues  during the
period ended December 31, 1998 were earned from  construction  services provided
to Ledcor.

     (i)  Senior Notes

     On July 28, 1999 the Company  issued  Senior notes (the "12% Notes") with a
face  value of  $500,000,000.  The 12% Notes are  unsecured  obligations  of the
Company  bearing  interest at 12% payable  semi-annually.  The 12% Notes are due
August 1, 2009 and may be redeemed by the Company on or after  August 1, 2000 at
certain specified  redemption prices. Up to 35% of the 12% Notes may be redeemed
by the Company  prior to August 1, 2002 with the net proceeds from certain sales
of the Company's common stock.

     The 12% 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.

     The  interest  rate on the 12% Notes is subject to  increase if the Company
does  not  file a  registration  statement  with  the  Securities  and  Exchange
Commission within certain time periods specified in the 12% Notes Indenture.

            (tabular amounts expressed in thousands of U.S. dollars)

     (ii) Agreement with Tyco Submarine Systems Ltd.

     On June  18,  1999,  a  subsidiary  of the  Company  entered  into a supply
agreement,  with Tyco Submarine Systems Ltd. ("Tyco") whereby Tyco will serve as
the primary  contractor  for the Company's  transatlantic  cable project  called
"Hibernia".  The initial  contract  price is  approximately  $607  million.  The
Company has paid $60.7 million in advance payments to Tyco.

     (iii) Common stock

     In April 1999, the Company  granted stock options to employees and officers
to purchase an  aggregate  of  2,045,160  shares of class A common  stock of the
Company at a price of $10 per share. The stock options have terms expiring on
or before June 30, 2009.

     (iv) IC/CN Agreements

     On May 28, 1999, the Company entered into agreements with Canadian National
Railway Company ("CN") and Illinois  Central  Railroad Company ("IC") to license
rights-of-way  ("ROW") along  certain of their  respective  rail  transportation
systems (the "Routes").  The Company will pay a license fee, based on the length
of the ROWs, and payable pursuant to a formula based on cash flow generated from
projects developed on the Routes. The Company will also provide a certain number
of fibers as consideration for the license of the ROWs. In connection with these
license agreements,  the Company has formed subsidiary  companies with CN and IC
(the  Company  having a 75%  interest  and CN or IC  having  the  remaining  25%
interest)  for the purpose of licensing  the ROWs from CN and IC and  developing
the projects along the Routes.

     (v)  Agreement with Ledcor (unaudited)

     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,  upon closing,  the
Company issued to affiliates of Ledcor 4,500,000 Class C Multiple Voting shares.
In  addition,  the  Company  assumed  certain  rights  and  obligations  of  the
affiliates under their 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.  Management
estimates  that  based on  information  available  to date,  fixed  assets  will
increase by approximately $26,000,000, the cost of the assets in the accounts of
Ledcor, deferred income taxes will increase by approximately  $12,000,000,  as a
result of a higher tax cost versus  accounting  cost of fixed  assets,  accounts
payable will increase by approximately  $30,000,000,  the liability  recorded in
the accounts of Ledcor, and the stated amount of the Company's common stock will
increase by approximately $8,000,000.

     (vi) Share Reorganization

     Pursuant to a reorganization  of the Company's share capital,  on September
9, 1999,  the Company  amended its share  capital by  redesignating  all Class A
Voting Shares to Class B Subordinate  Voting  Shares,  cancelling  the remaining
classes of shares  and  creating  Class A  Non-Voting  Shares,  Class C Multiple
Voting  Shares,  and Series A and B  Preferred  Shares  and Series C  Redeemable
Preferred  Shares.  Subsequently,  the  Company  declared  a stock  dividend  of
5,000,000  Series C  Redeemable  Preferred  Shares.  Concurrently,  the  Company
repurchased the 25,000,000  outstanding  Class B Subordinate  Voting Shares from
its parent in exchange for the issuance of 23,043,500 Class B Subordinate Voting
Shares and 40,000,000  Series C Redeemable  Preferred  Shares.  The Company then
redeemed the 45,000,000  outstanding  Series C Redeemable  Preferred  Shares for
$45,000,000 of cash.

     (vii) Issuance of Shares

     On August 31, 1999 the Company  issued  150,000 Class B Subordinate  Voting
Shares  (redesignated  from Class A Voting Shares) for $3,000,000 of cash and on
September 9, 1999, the Company issued  8,866,808  Series A Non-Voting  Preferred
Shares for $345,000,000 of cash.

     (viii) Credit Facility

     On July 6, 1999, the Company entered into a commitment  letter with certain
lenders  pursuant  to which  the  lenders  would  provide a  three-year  secured
revolving credit facility totalling  US$150,000,000.  The execution and delivery
of the definitive documentation is in progress.

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

1.   The Company

     Worldwide  Fiber (USA),  Inc. (the  "Company"),  formerly  known as Pacific
Fiber Link,  Inc., 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") (formerly Pacific
Fiber Link, LLC) 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

    (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.

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.

            (tabular amounts expressed in thousands of U.S. dollars)

     Return of capital

Directors.

     Redemption and retraction

     The Company may redeem or  purchase  Class B preferred  shares at such time

preferred shares adopted by the Board of Directors.

     b) Common shares

     The Company is authorized to issue 25,000 non-voting common shares, without
par value.  As at December 31, 1998,  there were 200  non-voting  common  shares
issued.

5.   Provision for income taxes

     The provision for current income taxes  attributable to net income consists
of the following:

         U.S. federal.................................................  $953
         U.S. state and local.........................................    27
                                                                      ======
                                                                        $980
                                                                      ======

     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.

construction  and  installation  of fiber  optic  network  assets in the  United

                                AUDITORS' REPORT

To the Directors of
Ledcor Industries Limited

         We have  audited the  divisional  balance  sheets of Ledcor  Industries
Limited--Telecommunications  Division  as at May 31,  1998,  August 31, 1997 and
August  31,  1996 and the  divisional  statements  of  operations  and  retained
earnings  and cash  flows for the nine  months  ended May 31,  1998,  year ended
August 31,  1997,  five  months  ended  August 31, 1996 and year ended March 31,
1996.  These  financial  statements  are the  responsibility  of the  Division's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

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

         In our opinion,  these divisional  financial statements present fairly,
in all material  respects,  the financial position of the Division as at May 31,
1998,  August 31, 1997 and August 31, 1996 and the results of its operations and
cash flows for the periods ended May 31, 1998,  August 31, 1997, August 31, 1996
and March 31, 1996 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,
          which differ in some respects from those in Canada.  The impact of any
          differences in accounting policies on the financial  statements is not
          significant and therefore has not been discussed.

     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


                                      F-52

                  Notes to the Divisional Financial Statements

                        (All figures are in U.S. dollars)

          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.

     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:

          o    Construction   equipment--hourly   usage   rates,   estimated  to
               depreciate the equipment,  over estimated  useful lives,  ranging
               from three to five years.

          o    Fiber  optic  strands,   under   construction--depreciation,   at
               appropriate  rates,  will be provided for when the related  fiber
               optic systems are in use.

          o    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.

                        (All figures are in U.S. dollars)

     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.

     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:

      Nine months ending May 31, 1998                           $1,198,360
      Year ended August 31, 1997                                   497,265
      Five months ended August 31, 1996                             55,953
      Year ended March 31, 1996                                     38,670

10.  SIGNIFICANT CONCENTRATION OF CREDIT AND SUPPLY RISK

     The following  customers/supplier  have accounted  individually  for 10% or
more of the Division's total  revenues/contract costs in one or more periods, as
follows:

     The Division also had significant  accounts  receivable from fONOROLA which
accounted for the following percentages of trade accounts receivable:

                                                               May 31, 1998      August 31, 1997    August 31, 1996
                                                               ------------      ---------------    ---------------

   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.

                  Notes to the Divisional Financial Statements

                        (All figures are in U.S. dollars)

     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.

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

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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Pursuant to the By-laws of the Company, as amended, subject to Section 124
of the Canada Business Corporations Act (the "Act"), a director or officer of
the Company, a former director or officer of the Company or a person who acts or
acted at the Company's request as a director or officer of a body corporate of
which the Company is or was a shareholder or creditor, and his or her heirs and
legal representatives:

1.   may be indemnified by the Company against all costs, charges and expenses,
     including an amount paid to settle an action or satisfy a judgment,
     reasonably incurred by him or her in respect of any civil, criminal or
     administrative action or proceeding to which he or she is made a party by
     reason of being or having been a director or officer of such Company or
     body corporate.

2.   may be indemnified by the Company, with the approval of a court, against
     all costs, charges and expenses reasonably incurred by him or her in
     connection with an action by or on behalf of the Company or body corporate
     to procure a judgment in its favor, to which he or she is made a party by
     reason of being or having been a director or an officer of the Company or
     body corporate; and

3.   is entitled to indemnity from the Company in respect of all costs, charges
     and expenses reasonably incurred by him or her in connection with the
     defense of any civil, criminal or administrative action or proceeding to
     which he or she is made a party by reason of being or having been a
     director or officer of the Company or body corporate, if the person seeking
     indemnity was substantially successful on the merits in his or her defense
     of the actions or proceeding:

provided, in all cases, such person fulfills the conditions that (a) he or she
acted honestly and in good faith with a view to the best interests of the
Company, and (b) in the case of a criminal or administrative action or
proceeding that is enforced by a monetary penalty, he or she had reasonable
grounds for believing that his or her conduct was lawful.

     As contemplated by Section 124 of the Canada Business Corporations Act, the
Company has purchased insurance against potential claims against the directors
and officers of the registrant and against loss for which the registrant may be
required or permitted by law to indemnify such directors and officers.

Item 22. UNDERTAKINGS.

     (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.

     The undersigned registrant hereby undertakes:

     (2) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) to include any
prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) to
reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the registration statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; (iii) to include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement.

     (3) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment 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.

     (4) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (5) To file a post-effective amendment to the registration statement to
include any financial statements required by ss.210.3-19 of this chapter at the
start of any delayed offering or throughout a continuous offering.

     (6) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the infor-



                                      II-7
<PAGE>

mation called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other Items of the applicable form.

     (7) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415 (ss.230.415 of this chapter), will
be filed as a part of an amendment to the registration statement and will not be
used until such amendment is effective, and that, for purposes of determining
any liability under the Securities Act of 1933, each such post-effective
amendment 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.

     (8) The undersigned registrant hereby undertakes: (i) to respond to
requests for information that is incorporated by reference into this prospectus
pursuant to Items 4, 10(b), 11 or 13 of this Form F-4, within one business day
of receipt of such request, and to send the incorporated documents by first
class mail or other equally prompt means; and (ii) to arrange or provide for a
facility in the U.S. for the purpose of responding to such requests. The
undertaking in subparagraph (i) above includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

     (9) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     (10) The undersigned registrant hereby undertakes to file an application
for the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act ("Act") in accordance
with the rules and regulations prescribed by the Commission under Section
305(b)(2) of the Act.

Dear Sirs:

     Worldwide Fiber Inc., a corporation incorporated under the laws of Alberta
(the "Company"), proposes to issue and sell to Donaldson, Lufkin & Jenrette
Securities Corporation, Morgan Stanley & Co. Incorporated, Salomon Smith Barney
Inc. and TD Securities (USA) Inc. (each, an "Initial Purchaser" and, together,
the "Initial Purchasers") an aggregate of U.S. $500,000,000 in principal amount
of its 12% Series A Senior Notes due 2009 (the "Series A Notes"), subject to the
terms and conditions set forth herein. The Series A Notes are to be issued
pursuant to the provisions of an indenture (the "Indenture"), to be dated as of
the Closing Date (as defined below), between the Company and HSBC Bank USA, as
trustee (the "Trustee"). The Series A Notes and the Series B Notes (as defined
below) issuable in exchange therefor are collectively referred to herein as the
"Notes." Capitalized terms used but not defined herein shall have the meanings
given to such terms in the Indenture.

     1. Offering Memorandum. The Series A Notes will be offered and sold to the
Initial Purchasers pursuant to one or more exemptions from the registration
requirements under the Securities Act of 1933, as amended (the "Act"). The
Company has prepared a preliminary offering memorandum, dated July 1, 1999 (the
"Preliminary Offering Memorandum"), a preliminary Canadian addendum, dated July
1, 1999 (the "Preliminary Wrap"), a final offering memorandum, dated July 23,
1999 (the "Offering Memorandum"), and a final Canadian addendum, dated July 23,
1999 (the "Final Wrap"), in each case, relating to the Series A Notes. The
Issuer hereby confirms that it has authorized the use of the Preliminary
Offering Memorandum, the Preliminary Wrap, the Offering Memorandum and the Final

Wrap, and any amendment or supplement thereto, in connection with the offer and
sale of the Series A Notes by the Initial Purchasers. Unless stated to the
contrary, all references herein (i) to the "Preliminary Canadian Memorandum" are
to the Preliminary Offering Memorandum as supplemented by the Preliminary Wrap;
and (ii) to the "Final Canadian Memorandum" are to the Offering Memorandum as
supplemented by the Final Wrap.

     Upon original issuance thereof, and until such time as the same is no
longer required pursuant to the Indenture, the Series A Notes (and all
securities issued in exchange therefor, in substitution thereof or upon
conversion thereof) shall bear the following legend:

     "THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S.
     SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
     ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
     WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
     PERSONS, EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS ACQUISITION
     HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER: (1) REPRESENTS THAT
     (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER
     THE ACT)(A "QIB"), (B) IT HAS ACQUIRED THIS NOTE IN AN OFFSHORE TRANSACTION
     IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, OR (C) IT IS AN
     INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),(2),(3)
     OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN "IAI"), (2) AGREES
     THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A) TO THE
     COMPANY OR ANY OF ITS SUBSIDIARIES, (B) TO A PERSON WHOM THE SELLER
     REASONABLY BELIEVES IS A QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE
     ACCOUNT OF A QIB IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A,
     (C) IN AN OFFSHORE TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR 904
     OF THE ACT, (D) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER
     THE SECURITIES ACT, (E) TO AN IAI THAT, PRIOR TO SUCH TRANSFER, FURNISHES
     THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
     AGREEMENTS RELATING TO THE TRANSFER OF THIS NOTE (THE FORM OF WHICH CAN BE
     OBTAINED FROM THE TRUSTEE) AND, IF SUCH TRANSFER IS IN RESPECT OF AN
     AGGREGATE PRINCIPAL AMOUNT OF NOTES LESS THAN $250,000, AN OPINION OF
     COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH
     THE SECURITIES ACT, (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
     REGISTRATION

     REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL
     ACCEPTABLE TO THE COMPANY) OR (G) PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES
     LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION
     AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN
     INTEREST HEREIN IS TRANSFERRED, A NOTICE SUBSTANTIALLY TO THE EFFECT OF
     THIS LEGEND. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND "UNITED
     STATES" HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER
     THE ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE
     TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING."

     2. Agreements to Sell and Purchase. On the basis of the representations,
warranties and covenants contained in this Agreement, and subject to the terms
and conditions contained herein, the Company agrees to issue and sell to the
Initial Purchasers, and each Initial Purchaser agrees, severally and not
jointly, to purchase from the Company, the principal amounts of Series A Notes
set forth opposite the name of such Initial Purchaser on Schedule A hereto at a
purchase price equal to 97.0% of the principal amount thereof (the "Purchase
Price").

     3. Terms of Offering. The Initial Purchasers have advised the Company that

state securities commission or any securities commission of a Relevant Province
(as defined below) of any stop order suspending the qualification or exemption
from qualification of any Series A Notes for offering or sale in any

Preliminary Canadian Memorandum, the Offering Memorandum, or the Final Canadian
Memorandum untrue or that requires any additions to or changes in the
Preliminary Offering Memorandum, the Preliminary Canadian Memorandum, the
Offering Memorandum, or the Final Canadian Memorandum in order to make the
statements therein not misleading. The Company shall use its best efforts to
prevent the issuance of any stop order or order suspending the qualification or
exemption of any Series A Notes under any state securities or Blue Sky laws or
Canadian Securities Laws (as defined below) and, if at any time any state
securities commission or other federal or state regulatory authority shall issue
an order suspending the qualification or exemption of any Series A Notes under

below), the Company shall use its best efforts to obtain the withdrawal or
lifting of such order at the earliest possible time.

     (b) To furnish the Initial Purchasers and those persons identified by the
Initial Purchasers to the Company as many copies of the Preliminary Offering
Memorandum, the Preliminary Canadian Memorandum, the Offering Memorandum and the

by the Initial Purchasers in connection with Exempt Resales.

     (c) During such period as in the opinion of counsel for the Initial
Purchasers an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchasers, (i) not to make any
amendment or supplement to the Offering Memorandum or the Final Canadian
Memorandum of which the Initial Purchasers shall not previously have been
advised or to which the Initial Purchasers shall reasonably object after being
so advised and (ii) to prepare promptly upon the Initial Purchasers' reasonable
request, any amendment or supplement to the Offering Memorandum or the Final
Canadian Memorandum which may be necessary or advisable in connection with such
Exempt Resales.

     (d) If, during the period referred to in Section 5(c) above, any event

the Offering Memorandum or the Final Canadian Memorandum in order to make the
statements therein, in the light of the circumstances when such Offering
Memorandum or the Final Canadian Memorandum is delivered to an Eligible
Purchaser, not misleading, or if, in the opinion of counsel to the Initial
Purchasers, it is necessary to amend or supplement the Offering Memorandum or
the Final Canadian

the Canadian Securities Laws as the Initial Purchasers may request and to
continue such registration or qualification in effect so long as required for
Exempt Resales and to file such consents to service of process or other
documents as may be necessary in order to effect such registration or
qualification; provided, however, that the Company shall not be required in
connection therewith to qualify as a foreign corporation in any jurisdiction in
which it is not now so qualified or to take any action that would subject it to

damages, liabilities and judgments (including, without limitation, any legal or
other expenses incurred in connection with investigating or defending any
matter, including any action, that could give rise to any such losses, claims,
damages, liabilities or judgments) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Offering Memorandum (or any
amendment or supplement thereto), the Final Canadian Memorandum (or any
amendment or supplement thereto), the Preliminary Offering Memorandum, the
Preliminary Canadian Memorandum or any Rule 144A Information provided by the
Company to any holder or prospective purchaser of Series A Notes pursuant to
Section 5(h) or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by any such untrue statement or omission or alleged untrue
statement or omission based upon information furnished in writing to the Company
by such Initial Purchasers expressly for use in the Preliminary Offering
Memorandum, the Preliminary Canadian Memorandum, the Offering Memo-


<PAGE>
                                      -24-


randum or the Final Canadian Memorandum; provided, however, that the foregoing
indemnity agreement with respect to any Preliminary Offering Memorandum or
Preliminary Canadian Memorandum, as the case may be, shall not inure to the
benefit of any Initial Purchaser who failed to deliver an Offering Memorandum or
Final Canadian Memorandum, as then amended or supplemented, (so long as the
Offering Memorandum or Final Canadian Memorandum and any amendment or supplement
thereto was provided by the Company to the Initial Purchasers in the requisite
quantity and on a timely basis to permit proper delivery on or prior to the
Closing Date) to the person asserting any losses, claims, damages, liabilities
or judgments caused by any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Offering Memorandum or Preliminary
Canadian Memorandum, as the case may be, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, if such material
misstatement or omission or alleged material misstatement or omission was cured
in the Offering Memorandum or the Final Canadian Memorandum, as so amended or
supplemented.

     (b) The Initial Purchasers agree severally, not jointly, to indemnify and
hold harmless the Company, its directors and officers and each person, if any,
who controls (within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act) the Company, to the same extent as the foregoing indemnity from
the Company to the Initial Purchasers but only with reference to information
furnished in writing to the Company by the Initial Purchaser expressly for use
in the Preliminary Offering Memorandum, the Preliminary Canadian Memorandum, the
Offering Memorandum or the Final Canadian Memorandum, as applicable.

     (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), the Initial Purchasers shall not be required to
assume the defense of such action pursuant to this Section 8(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
the Initial Purchasers). Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the


<PAGE>
                                      -25-


indemnifying party, and the indemnified party shall have been advised by such
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the indemnifying party (in
which case the indemnifying party shall not have the right to assume the defense
of such action on behalf of the indemnified party). In any such case, the
indemnifying party shall not, in connection with any one action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys with respect to matters of
U.S. law and one separate firm of attorneys with respect to matters of Canadian
law (in each case, in addition to any local counsel) for all indemnified parties
and all such fees and expenses shall be reimbursed as they are incurred. Such
firms shall be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation, in the case of the parties indemnified pursuant to Section 8(a),
and by the Company, in the case of parties indemnified pursuant to Section 8(b).
The indemnifying party shall indemnify and hold harmless the indemnified party
from and against any and all losses, claims, damages, liabilities and judgments
by reason of any settlement of any action (i) effected with its written consent
or (ii) effected without its written consent if the settlement is entered into
more than twenty business days after the indemnifying party shall have received
a request from the indemnified party for reimbursement for the fees and expenses
of counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action 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 the indemnified party.

     (d) To the extent the indemnification provided for in this Section 8 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Initial Purchasers on the other hand from the
offering of the Series A Notes or (ii) if the allocation provided by clause
8(d)(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
8(d)(i) above but also the relative fault of the Company, on the one hand, and
the Initial Purchasers, on the other hand, in connection with the statements or
omissions which resulted in


<PAGE>
                                      -26-


such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations. The relative benefits received by the
Company, on the one hand and the Initial Purchasers, on the other hand, shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Series A Notes (after underwriting discounts and commissions, but before
deducting expenses) received by the Company, and the total discounts and
commissions received by the Initial Purchasers bear to the total price to
investors of the Series A Notes, in each case as set forth in the table on the
cover page of the Offering Memorandum. The relative fault of the Company, on the
one hand, and the Initial Purchasers, on the other hand, 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, on the one hand, or the Initial
Purchasers, on the other hand, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     The Company, and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Initial Purchasers 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 in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, the Initial
Purchasers shall not be required to contribute any amount in excess of the
amount by which the total discounts and commissions received by such Initial
Purchasers exceeds the amount of any damages which the Initial Purchaser 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 Initial Purchasers' obligation to contribute pursuant to
this Section 8(d) are several and in proportion to the respective principal
amount of Series A Notes purchased by each of the Initial Purchasers hereunder
and not joint.

     (e) The remedies provided for in this Section 8 are not exclusive and shall
not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     (f) For purposes of this Section 8, the Company and the Initial Purchasers
agree that the only information furnished in writing to the Company by the
Initial Purchasers expressly for use in the Preliminary Offering Memorandum, the
Preliminary Canadian Memo-

randum, the Offering Memorandum or the Final Canadian Memorandum is set forth in
the third, fourth, fifth, sixth (excluding the first three sentences), seventh,
eighth and ninth paragraphs under the heading "Plan of Distribution."

subject to the satisfaction of each of the following conditions:

     (a) All the representations and warranties of the Company contained in this

review (or of any potential or intended review) for a possible change that does
not indicate the direction of the possible change in, any rating of the Company
or any securities of the Company (including, without limitation, the placing of
any of the foregoing ratings on credit watch with negative or developing
implications or under review with an uncertain direction) by any "nationally
recognized statistical rating organization" as such term is defined for purposes
of Rule 436(g)(2) under the Act, (ii) there shall not have occurred any change,
nor shall any notice have been given of any potential or intended change, in the
outlook for any rating of the Company or any securities of the Company by any
such rating organization and (iii) no such rating organization shall have given
notice that it has assigned (or is considering assigning) a lower rating to the
Notes than that on which the Notes were marketed.

     laws of Canada or the Provinces of Alberta and British Columbia is
     necessary in order to preserve or protect the validity or enforceability of
     the Indenture or the Notes issued thereunder;

          (xxiii) to the knowledge of such counsel, there is no pending or
     threatened action or suit or judicial, arbitral or other administrative
     proceeding to which the Canadian Companies are subject that, singly or in
     the aggregate, (A) questions the validity of any of the Operative Documents
     or any action taken or to be taken pursuant thereto, or (B) if determined
     adversely to the Canadian Companies, is reasonably likely to have a
     Material Adverse Effect;

          (xxiv) the choice of law provisions set forth in Section 11 hereof, in
     the Indenture, the Registration Rights Agreement and the Notes are 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 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, the
     Indenture, the Registration Rights Agreement and the Notes and if the
     Indenture, this Agreement, the Registration Rights Agreement or the Notes
     are 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, the Indenture, the Notes or the Registration Rights 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;

          (xxv) 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 the Indenture or the Notes would be
     avoided on the grounds of Public Policy;


<PAGE>
                                      -36-


          (xxvi) 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 11 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 for the purpose described in the Indenture, the Notes and the
     Registration Rights Agreement 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 in the
     Indenture, the Notes and the Registration Rights Agreement 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;

          (xxvii) service of process in the manner set forth in Section 11
     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; service of process in the manner set
     forth in the Indenture, the Notes and the Registration Rights Agreement
     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;

          (xxviii) 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, the Indenture, the
     Notes and the Registration Rights 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, the
     Indenture, the Notes and the Registration Rights Agreement to the
     jurisdiction of the


<PAGE>
                                      -37-


     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 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, the Indenture, the
     Notes and the Registration Rights Agreement under the laws of the Province
     of British Columbia and the federal laws of Canada applicable therein;

          (xxix) no withholding tax imposed under the federal laws of Canada or
     the laws of the Province of British Columbia will be payable in respect of
     the payment or crediting of any discount, commission or fee as contemplated
     by this Agreement to an Initial Purchaser that is not resident in Canada,
     but resident in the United States or if a partnership, all the members of
     which are not resident in Canada but resident in the United States, in each
     case, for purposes of the Income Tax Act (Canada) and the Canada-U.S.
     Income Tax Convention, 1980 (a "U.S. Initial Purchaser") or on any interest
     or deemed interest on the resale of Series A Notes by a U.S. Initial
     Purchaser to U.S. residents, provided that such U.S. Initial Purchaser
     deals at arm's length with the Company and that any such discount,
     commission or fee is payable in respect of services rendered by such U.S.
     Initial Purchaser outside of Canada that are performed by such U.S. Initial
     Purchaser in the ordinary course of business carried on by it that includes
     the performance of such services for a fee and any such amount is
     reasonable in the circumstances.

          (xxx) no goods and services tax imposed under the federal laws of
     Canada will be collectible by a U.S. Initial Purchaser in respect of the
     payment or crediting of any discount, commission or fee as contemplated by
     this Agreement to any U.S. Initial Purchaser, provided that any such
     discount, commission or fee is payable in respect of services performed by
     such Initial Purchaser wholly outside of Canada.

     sale and delivery to a U.S. Initial Purchaser of the Series A Notes or the
     authorization, execution and delivery and performance of this Agreement,
     any pricing agreement, or the Indenture or the resale of Series A Notes by

<PAGE>
                                      -42-


elsewhere that, in the Initial Purchasers' judgment, is material and adverse

     If on the Closing Date any one or more of the Initial Purchasers shall fail
or refuse to purchase the Series A Notes which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of the Series
A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the
case may be, agreed but failed or refused to purchase is not more than one-tenth
of the aggregate principal amount of the Series A Notes to be purchased on such
date by all Initial Purchasers, each non-defaulting Initial Purchaser shall be
obligated severally, in the proportion which the principal amount of the Series
A Notes set forth opposite its name in Schedule A bears to the aggregate
principal amount of the Series A Notes which all the non-defaulting Initial
Purchasers, as the case may be, have agreed to purchase, or in such other
proportion as you may specify, to purchase the Series A Notes which such
defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed
but failed or refused to purchase on such date; provided that in no event shall
the aggregate principal amount of the Series A Notes which any Initial Purchaser
has agreed to purchase pursuant to Section 2 hereof be increased pursuant to
this Section 10 by an amount in excess of one-ninth of such principal amount of
the Series A Notes without the written consent of such Initial Purchaser. If on
the Closing Date any Initial Purchaser or Initial Purchasers shall fail or
refuse to purchase the Series A Notes and the aggregate principal amount of the
Series A Notes with respect to which such default occurs is more than one-tenth
of the aggregate principal amount of the Series A Notes to be purchased by all
Initial Purchasers and arrangements satisfactory to the Initial Purchasers and
the Company for purchase of such the Series A Notes are not made within 48 hours
after such default, this Agreement will terminate without liability on the part
of any non-defaulting Initial Purchaser and the Company. In any such case which
does not result in termination of this Agreement, either you or the Company
shall have the right to


<PAGE>
                                      -43-


postpone the Closing Date, but in no event for longer than seven days, in order
that the required changes, if any, in the Offering Memorandum or any other
documents or arrangements may be effected. Any action taken under this paragraph
shall not relieve any defaulting Initial Purchaser from liability in respect of
any default of any such Initial Purchaser under this Agreement.

     11. Jurisdiction. The Company and its subsidiaries agree that any suit,
action or proceeding against them brought by any Initial Purchaser, the
directors, officers, employees and agents of any Initial Purchaser, or by any
person who controls any Initial Purchaser, 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. The Company 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 Initial Purchaser, the directors,
officers, employees and agents of any Initial Purchaser, or by any person, if
any, who controls any Initial Purchaser, and expressly accept the non-exclusive
jurisdiction of any such court in respect of any such suit, action or
proceeding. The Company 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 the Company 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. Notwithstanding the foregoing, any action arising out of or based upon
this Agreement may be instituted by any Initial Purchaser, the directors,
officers, employees and agents of any Initial Purchaser, or by any person who
controls any Initial Purchaser, in any court of competent jurisdiction in
Canada.

investigation, or statement as to the results thereof, made by or on behalf of
the Initial Purchasers, the officers or directors of the Initial Purchasers, any
person controlling the Initial Purchasers, the Company, the officers or
directors of the Company, or any person controlling the Company and (ii)
acceptance of the Series A Notes and payment for them hereunder. The respective
agreements, covenants and indemnities set forth in Sections 5(i) and 8 hereof
shall remain in full force and effect, regardless of any termination or
cancellation of this Agreement.

     If for any reason the Series A Notes are not delivered by or on behalf of
the Company as provided herein (other than as a result of any termination of
this Agreement pursuant to Section 10), the Company agrees to reimburse the
Initial Purchasers for all reasonable out-of-pocket expenses (including the fees
and disbursements of counsel) incurred by them. Notwithstanding any termination
of this Agreement, the Company shall be liable for all expenses which it has
agreed to pay pursuant to Section 5(i) hereof. The Company also agrees to
reimburse the Initial Purchasers and its officers, directors and each person, if
any, who controls such Initial Purchaser within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act for any and all fees and expenses
(including without limitation the fees and expenses of counsel) incurred by them
in connection with enforcing their rights under this Agreement (including
without limitation its rights under Section 8).

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Initial
Purchasers, the Initial Purchasers' directors and officers, any controlling
persons referred to herein, the directors of the Company and their respective
successors and assigns, all as and to the extent provided in this Agreement, and
no other person shall acquire or have any right under or by virtue of this
Agreement. The term "successors and assigns" shall not include a purchaser of
any of the Series A Notes from the Initial Purchasers merely because of such
purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.

6.2. The redemption price or the purchase price for the Class "II" Preferred
     Shares, surrendered for redemption or for sale shall be such amount as may

     dividends thereon.

     Class "III" Preferred Shares

6.3. The price or consideration payable entirely in lawful money of Canada at
     which the Class "III" Preferred Shares shall be redeemed (the "Class "III"
     Redemption Amount") shall be the amount of consideration received therefor

     the Directors and if the Directors or a competent Court or tribunal agree
     with such revaluation and all appeal rights have been exhausted or all
     times for appeal have expired without appeals having been taken or should
     the Directors of the Corporation otherwise determine that the fair market
     value of the Class "III" Purchased Assets is other than the amount
     previously approved by the Directors, then the Class "III" Redemption
     Amount of the Class "III" Purchased Shares shall be adjusted nunc pro tunc
     pursuant to the provisions of this paragraph to reflect the agreed upon
     fair market value and all necessary adjustments, payments and repayments as
     may be required shall forthwith be made between the proper parties.

7.   LIQUIDITY

7.1. Notwithstanding anything to the contrary herein contained, no dividends or
     other payment or distribution shall be made to the holders, as such, of
     shares in the capital stock of the Corporation other than Class "I"
     Preferred Shares, Class "II" Preferred Shares and Class "III" Preferred
     Shares if the payment thereof would result in the fair market value of the
     Corporation's assets, net of liabilities owed by the Corporation, being
     less than the aggregate of the redemption or purchase price of all Class
     "I" Preferred Shares, Class "II" Preferred Shares and Class "III" Preferred
     Shares then outstanding.

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 Corporation 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
Corporation, the assets of the Corporation 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 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 Corporation and shall not be entitled to share in any further
distribution of assets of the Corporation.

     (3) Any consolidation, merger or other business combination of the
Corporation 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



                                      -10-
<PAGE>

such merger, consolidation or other business combination where, after the
completion of such transaction, the holders of voting shares in the capital of
the Corporation 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 Corporation 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
Corporation 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 Corporation 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 Corporation, 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
Corporation, 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.



                                      -11-
<PAGE>

     (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 Corporation 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 Corporation 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 Corporation 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 Corporation or of securities convertible into, or exchangeable or
exercisable for, shares of Common Shares of the Corporation, (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 Corporation, 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 Corporation 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 Corporation 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



                                      -12-
<PAGE>

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 Corporation upon issuance of such Common Shares or Common Share
Equivalents or receivable by the Corporation 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 Corporation 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,



                                      -13-
<PAGE>

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 Corporation upon
issuance of such Common Shares or Common Share Equivalents or receivable by the
Corporation 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 Corporation 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 Corporation
of fiber assets and related rights and 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 Corporation; (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;
or (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).

     (d) For purposes of this Section 1.6(2) the aggregate consideration
receivable by the Corporation 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 Corporation 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 Corporation prior to


                                      -14-
<PAGE>

amounts paid or payable for accrued interest or accrued dividends and prior to
any commissions or expenses paid by the Corporation;

     (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 Corporation 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
Corporation).

     (f) If the Corporation 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) (a) Before the Corporation shall be entitled to convert Series A
Non-Voting Preferred Shares into Class A Non-Voting Shares pursuant to Section
1.6(1) of



                                      -15-
<PAGE>

this Article C, the Corporation 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 Corporation 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
Corporation shall be irrevocable.

     (b) Within three (3) days following the Conversion Date, the Corporation
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, 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.

     (c) The Corporation 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 Corporation 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


                                      -16-
<PAGE>

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 Corporation or of
any transfer agent for the Series A Non-Voting Preferred Shares, together with a
written notice to the Corporation 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 Corporation 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



                                      -17-
<PAGE>

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.

     (6) The Corporation 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 Schedule II to these Articles.

     (7) As used in this Section 1.6 the term "Class A Non-Voting Shares" shall
mean and include the Corporation'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 Corporation 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 Corporation 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 Corporation 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 Corporation shall be a party to any transaction including
without limitation, an amalgamation, arrangement, consolidation, sale of all or
substantially all of the Corporation's assets or a reorganization,
reclassification or recapitalization of the capital of the Corporation 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 Corporation 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 Corporation shall not effect any Transaction unless prior to or
simultaneously with the consummation thereof the Corporation



                                      -18-
<PAGE>

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 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 Corporation'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 Corporation 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 Corporation, 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,



                                      -19-
<PAGE>

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

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

     (4) the Corporation shall authorize the consolidation or merger of the
Corporation 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 Corporation shall authorize the voluntary or involuntary
dissolution, liquidation or winding up on the Corporation,

then the Corporation 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 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
Corporation shall promptly deliver to each of the holders of the Series A
Non-Voting Preferred Shares, a certificate signed by an officer of 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

     1.9 Mandatory Redemption

     On November 2, 2009 (the "Redemption Date"), the Corporation 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 Corporation 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
Corporation shall be obligated on the Redemption Date to pay and deliver share
certificates to the holder thereof (upon surrender by such holder at the
Corporation'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 Corporation 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 Corporation 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 Corporation 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



                                      -21-
<PAGE>

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
Corporation 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 Corporation 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.

     1.2 Dividends

     The holders of Series B Subordinate Voting Preferred Shares shall be
entitled to receive dividends equivalent on a per share basis to any dividends
declared, paid, issued or distributed with respect to shares of Common Shares
into which such share of Series B Subordinate Voting Preferred Shares could be
converted pursuant to the provisions of Section 1.6 of this Article D, 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 Corporation shall not

     1.5 Liquidation, Dissolution or Winding Up

     (1) Upon (i) any liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary, (ii) a sale of all or substantially all of the
assets of the Corporation or (iii) a reorganization of the Corporation 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 Voting Preferred Shares
shall be entitled to receive and to be paid out of assets of



                                      -27-
<PAGE>

the Corporation available for distribution to its shareholders, before any
payment or distribution shall be made on any Junior Shares, the greater of (i)
the Series B Subordinate Voting Liquidation Value with respect to each such
outstanding Series B Subordinate Voting Preferred Share, and (ii) the amount
which would have been paid in such Liquidation, based upon the number of Class B
Subordinate Voting Shares into which a Series B Subordinate Voting Preferred
Share could be converted pursuant to the provisions of Section 1.6 of this
Article D. If, upon any Liquidation of the Corporation, the assets of the
Corporation available for distribution shall be insufficient to pay in full the
Series B Subordinate Voting Liquidation Value with respect to each outstanding
Series B Subordinate Voting Preferred Share, then such assets shall be
distributed among the holders of Series B Subordinate Voting Preferred Shares
ratably in accordance with the respective amounts that would be payable on such
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 Corporation and shall not be entitled to share in
any further distribution of assets of the Corporation.

     (3) Any consolidation, merger or other business combination of the
Corporation 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 Corporation
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 Corporation 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 Value
shall also be subject to adjustment as provided in Section 1.5(6) of this
Article D.



                                      -28-
<PAGE>

     (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
Corporation 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 Corporation 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 Corporation, 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 Corporation, 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 Corporation 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 Corporation 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 Corporation 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



                                      -29-
<PAGE>

Corporation or of securities convertible into, or exchangeable or exercisable
for, shares of Common Shares of the Corporation, (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 Corporation, 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 Corporation 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 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 Corporation 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
Corporation upon issuance of such Common Shares or Common Share Equivalents or
receivable by the Corporation 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



                                      -30-
<PAGE>

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 Corporation 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 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 Corporation upon issuance of such Common Shares or Common Share Equivalents
or receivable by the Corporation 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

Corporation; (iv) any Class A Non-Voting Shares issued on conversion of the
Series B Subordinate Voting Shares; (v) any Common Shares or Common Share
Equivalents issued pursuant to a Minority Roll-Up Transaction; or (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).

     (d) For purposes of this Section 1.6(2) the aggregate consideration
receivable by the Corporation 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 Corporation 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 Corporation prior to
amounts paid or payable for accrued interest or accrued dividends and prior to
any commissions or expenses paid by the Corporation;

     (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 Corporation 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



                                      -32-
<PAGE>

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
Corporation).

     (f) If the Corporation 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) (a) Before the Corporation 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 Corporation 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 Corporation 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 present and surrender such shares for conversion. After the
giving of such notice in writing, the election of the Corporation shall be
irrevocable.



                                      -33-
<PAGE>

     (b) Within three (3) days following the Conversion Date, the Corporation
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.

     (c) The Corporation 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 Corporation 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 Corporation or of any
transfer agent for the Series B Subordinate Voting Preferred Shares, together
with a written notice to the Corporation 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;



                                      -34-
<PAGE>

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 Corporation 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 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
Corporation 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 Corporation 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 Schedule II for these Articles.

     (7) As used in this Section 1.6 the term "Class B Subordinate Voting
Shares" shall mean and include the Corporation'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



                                      -35-
<PAGE>

capital of the Corporation 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 Corporation 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
Corporation 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 Corporation shall be a party to any transaction including
without limitation, an amalgamation, arrangement, consolidation, sale of all or
substantially all of the Corporation's assets or a reorganization,
reclassification or recapitalization of the capital of the Corporation 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 shares or other securities or property to which a holder of the
number of Class B Subordinate Voting Shares of the Corporation 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 Corporation shall not effect
any Transaction unless prior to or simultaneously with the consummation thereof
the Corporation 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



                                      -36-
<PAGE>

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
Corporation'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 Corporation 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 Corporation, 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 Corporation shall declare a dividend (or any other distribution) on
its Common Shares;

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



                                      -37-
<PAGE>

     (4) the Corporation shall authorize the consolidation or merger of the
Corporation 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 Corporation shall authorize the voluntary or involuntary
dissolution, liquidation or winding up on the Corporation;

then the Corporation 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
Corporation shall promptly deliver to each of the holders of the Series B
Subordinate Voting Preferred Shares, a certificate signed by an officer of the
Corporation 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 Corporation 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 Corporation 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



                                      -38-
<PAGE>

Share which is to be redeemed, the Corporation shall be obligated on the
Redemption Date to pay and deliver share certificates to the holder thereof
(upon surrender by such holder at the Corporation'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
Corporation 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 Corporation 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 Corporation 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 Corporation 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.

<PAGE>

the Series B Subordinate Voting Preferred Shares. If the Corporation 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

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

                                  Section Eight

                  PROTECTION OF DIRECTORS, OFFICERS AND OTHERS


     8.01 Limitation of Liability. Every director and officer of the Corporation
in exercising his powers and discharging his duties shall act honestly and in
good faith with a view to the best interests of the Corporation and exercise the
care, diligence and skill that a reasonably prudent person would exercise in
comparable circumstances. Subject to the foregoing, no director or officer shall
be liable for the acts, receipts, neglects or defaults of any other director,
officer, or employee, or for joining in any receipt or other act for conformity,
or for any loss, damage or expense happening to the Corporation through the
insufficiency or deficiency of title to any property acquired for or on behalf
of the Corporation, or for the insufficiency or deficiency of any security in or
upon which any of the moneys of the Corporation shall be invested, or for any
loss or damage arising from the bankruptcy, insolvency or tortious acts of any
person with whom any of the moneys, securities or effects of the Corporation
shall be deposited, or for any loss occasioned by any error of judgement or
oversight on his part, or for any other loss, damage or misfortune which shall
happen in the execution of the duties of his office or in relation thereto;
provided that nothing herein shall relieve any director or officer from the duty
to act in accordance with the Act and the regulations thereunder or from
liability for any breach thereof. So long as he is not in breach of any
applicable statute, no person referred to in this paragraph shall be liable for
any damage, loss, cost or liability sustained or incurred by the Corporation.

     8.02 Indemnity. Subject to the Act, the Corporation shall indemnify a
director or officer of the Corporation, a former director or officer of the
Corporation, or a person who acts or acted at the Corporation's request as a
director or officer of a body corporate of which the Corporation is or was a
shareholder or creditor, and his heirs and legal representatives, against all
costs, charges and expenses, including an amount paid to settle an action or
satisfy a judgement, reasonably incurred by him in respect of any civil,
criminal or administrative action or proceeding to which he is made a party by
reason of being or having been a director or officer of the Corporation of such
body corporate, if:

     (a) he acted honestly and in good faith with a view to the best interests
of the Corporation; or

     (b) in the case of a criminal or administrative action or proceeding that
is enforced by a monetary penalty, he had reasonable grounds for believing that
his conduct was lawful.


<PAGE>
                                      -12-


     The Corporation shall also indemnify such person in such other
circumstances as the Act permits or requires. Nothing in this by-law shall limit
the right of any person entitled to indemnity to claim indemnity apart from the
provisions of this by-law.

     8.03 Indemnification in Derivative Actions. Subject to the Act, the
Corporation shall with the approval of a court indemnify a person referred to in
section 8.02 in respect of an action by or on behalf of the Corporation or body
corporate to procure a judgment in its favour, to which he is made a party by
reason of being or having been a director or an officer of the Corporation or
body corporate, against all costs, charges and expenses reasonably incurred by
him in connection with such action if he fulfils the conditions set out in
sections 8.02(a) and (b).

     8.04 Indemnity as of Right. Subject to the Act, a person referred to in
section 8.02 is entitled to indemnity from the Corporation in respect of all
costs, charges and expenses reasonably incurred by him in connection with the
defence of any civil, criminal or administrative action or proceeding to which
he is made a party by reason of being or having been a director or officer of
the Corporation or body corporate, if the person seeking indemnity:

     (a) was substantially successful on the merits in his defence of the action
or proceeding, and

     (b) fulfils the conditions set out in sections 8.02(a) and (b).

     8.05 Insurance. Subject to the Act, the Corporation shall purchase and
maintain insurance for the benefit of any person referred to in section 8.02
against any liability incurred by him in his capacity as a director or officer
of the Corporation or of another body corporate where he acts or acted in that
capacity at the Corporation's request, except where the liability relates to his
failure to act honestly and in good faith with a view to the best interests of
the body corporate.


                                  Section Nine

                       INTEREST OF DIRECTORS IN CONTRACTS


     9.01 Disclosure of Interest of Director or Officer. A director or officer
who is a party to, or who is a director or officer of or has a material interest
in any person who is a party to, a material contract or proposed material
contract with the Corporation shall in accordance with the Act disclose in
writing to the Corporation or request to have entered in the minutes of a
directors' meeting the nature and extent of his interest. A director so
inter-


<PAGE>
                                      -13-


ested shall not vote on or sign any resolution to approve such contract unless
permitted to do so by the Act. A general notice to the board by a director or
officer that he is a director or officer of or has a material interest in a
person and is to be regarded as interested in any contract made with that person
is a sufficient declaration of interest in relation to any contract so made.

     9.02 Effect of Such Contracts. A material contract is neither void nor
voidable by reason only that one or more of the directors or officers has a
material interest therein as aforesaid, or that an interested director is
present at or is included in constituting the quorum at a meeting of directors
that authorized the contract, if the director or officer disclosed his interest
in the manner referred to above and the contract was approved by the directors
or shareholders and was reasonable and fair to the Corporation at the time it
was approved.


                                   Section Ten

                                     SHARES


     10.01 Issuance of Shares. Subject to the provisions of the Act and the
articles, the board may from time to time issue or otherwise dispose of shares
of the Corporation, or grant options to purchase or otherwise deal in the whole
or any part of the authorized but unissued shares of the Corporation, at such
times and to such persons and for such consideration as the board shall
determine, provided that no share shall be issued until it is fully paid for as
provided by the Act.

     10.02 Commissions. The board may from time to time authorize the
Corporation to pay reasonable commission to any person in consideration of his
purchasing or agreeing to purchase shares of the Corporation, whether from the
Corporation or from any other person, or procuring or agreeing to procure
purchasers for any such shares.

     10.03 Share Certificates. Every shareholder is entitled to a share
certificate or a non-transferable written acknowledgement of his right to obtain
a share certificate, stating the number, class and series designation, if any,
of shares held by him as appearing in the records of the Corporation. Share
certificates shall be in such form or forms as the board shall from time to time
approve and, unless otherwise ordered by the board, shall be signed in
accordance with section 2.05 manually or as hereinafter provided, and need not
be under the corporate seal. Certificates representing shares in respect of
which a transfer agent has been ap-


<PAGE>
                                      -14-


pointed shall not be valid unless countersigned by or on behalf of such transfer
agent. The corporate seal of the Corporation and the signature of one of the
signing officers, or in the case of share certificates representing shares in
respect of which a transfer agent has been appointed, the signatures of both
signing officers, may be mechanically reproduced in facsimile upon share
certificates and every such facsimile signature shall bind the Corporation.
Share certificates executed as aforesaid shall be valid notwithstanding that one
or both of the officers whose signature (whether manual or facsimile) appears
thereon no longer holds office at the date of issue or delivery of the
certificate.

     10.04 Transfer Agent. The board may from time to time appoint or remove one
or more registrars and transfer agents to keep the securities register, appoint
or remove one or more branch transfer agents to keep branch securities registers
and provide for the transfer of securities in one or more places.

     10.05 Registration of Transfer. No transfer of shares need be registered in
the securities register except upon presentation of the certificate representing
such shares endorsed by an appropriate person in accordance with the Act,
together with reasonable assurance that the endorsement is genuine and
effective, upon compliance with such restrictions on transfer, if any, as are
authorized by the articles, upon satisfaction of any debt for which the
Corporation has a lien on the shares and upon compliance with all other
conditions set out in the Act.

     10.06 Lien for Indebtedness. If the articles so provide, when a shareholder
is indebted to the Corporation, the Corporation shall have a lien on shares
registered in the name of such shareholder or his legal representative to the
extent of the debt, and the right of the Corporation to the lien shall be noted
conspicuously on every share certificate. Subject to any other provision of the
articles, the Corporation may enforce such lien without notice or liability by
disposing of or cancelling without repayment any such shares, refusing to
register their transfer or setting off or recovering any dividends,
distributions or capital repayments due thereon.

     10.07 Non-recognition of Trusts. Subject to the Act, the Corporation may
treat the registered owner of a share as the person exclusively entitled to
vote, to receive notices, to receive any interest, dividend or other payments in
respect of the share and otherwise to exercise all the rights and powers of an
owner of the share. The Corporation may, however, treat as the registered
shareholder any executor, administrator, heir, legal representative, guardian,
committee, trustee, liquidator or trustee in bankruptcy who furnishes
appropriate evidence to the Corporation establishing his authority to exercise
the rights relating to a share of the Corporation.

     10.08 Joint Holders. If two or more persons are registered as joint holders
of any share, the Corporation shall not be bound to issue more than one
certificate in respect thereof, and delivery of such certificate to one of such
persons shall be sufficient delivery to all of them. Any one of such persons may
give effectual receipts for the certificate issued in


<PAGE>
                                      -15-


respect thereof or for any dividend, bonus, return of capital or other money
payable or warrant issuable in respect of such share.

     10.09 Deceased Shareholders. In the event of the death of a holder, or of
one of the joint holders, of any share, the Corporation shall not be required to
make any entry in the securities register in respect thereof or to make any
dividend or other payments in respect thereof except upon production of all such
documents as may be required by law and upon compliance with the reasonable
requirements of the Corporation and its transfer agents.

     10.10 Replacement of Share Certificates. The board or any officer or agent
designated by the board may at its or his discretion direct the issue of a new
share or other such certificate in lieu of and upon cancellation of a
certificate that has been mutilated or in substitution for a certificate claimed
to have been lost, destroyed or wrongfully taken on payment of such reasonable
fee and on such terms as to indemnity, reimbursement of expenses and evidence of
loss and of title as the board may from time to time prescribe, whether
generally or in any particular case.


                                 Section Eleven

                              DIVIDENDS AND RIGHTS


     11.01 Dividends. Subject to the Act, the board may from time to time
declare dividends payable to the shareholders according to their respective
rights and interest in the Corporation. Dividends may be paid in money or
property or by issuing fully paid shares of the Corporation.

     11.02 Dividend Cheques. A dividend payable in money shall be paid by cheque
to the order of each registered holder of shares of the class or series in
respect of which it has been declared and mailed by prepaid ordinary mail to
such registered holder at his recorded address, unless such holder otherwise
directs. In the case of joint holders the cheque shall, unless such joint
holders otherwise direct, be made payable to the order of all of such joint
holders and mailed to them at their recorded address. The mailing of such cheque
as aforesaid, unless the same is not paid on due presentation, shall satisfy and
discharge the liability for the dividend to the extend of the sum represented
thereby plus the amount of any tax which the Corporation is required to and does
withhold.

     11.03 Non-receipt of Cheques. In the event of non-receipt of any dividend
cheque by the person to whom it is sent as aforesaid, the Corporation shall
issue to such person a replacement cheque for a like amount on such terms as to
indemnity, reimbursement of


<PAGE>
                                      -16-


expenses and evidence of non-receipt and of title as the board may from time to
time prescribe, whether generally or in any particular case.

     11.04 Record Date for Dividends and Rights. The board may fix in advance a
date, preceding by not more than 50 days the date for the payment of any
dividend or the making of any distribution or the date for the issue of any
warrant or other evidence of right to subscribe for any security of the
Corporation, as a record date for the determination of the persons entitled to
receive such dividend or distribution or to exercise the right to subscribe for
such security, as the case may be, and notice of any such record date shall be
given not less than seven days before such record date. Where no such record
date is fixed by the board, the record date for the determination of the persons
entitled to receive such dividend or distribution or to exercise the right to
subscribe for such security, as the case may be, shall be the close of business
on the day on which the board passes the resolution relating to such dividend,
distribution or right.

     11.05 Unclaimed Dividends. Any dividend unclaimed after a period of six
years from the date on which the same has been declared to be payable shall be
forfeited and shall revert to the Corporation.


                                 Section Twelve

                            MEETINGS OF SHAREHOLDERS


     12.01 Annual Meeting. The annual meetings of shareholders shall be held at
such time in each year and, subject to the Act, at such place as the board may
determine, for the purpose of considering the financial statements and reports
required by the Act to be placed before the annual meeting, electing directors,
appointing an auditor and for the transaction of such other business as may
properly be brought before the meeting. In default of an annual general meeting
being held as required, an annual general meeting may be called by any two
shareholders and such meeting shall be conducted in the same manner, as nearly
as possible, as annual general meetings called by the directors.

     12.02 Special Meetings. The board shall have the power to call special
meetings of shareholders at such time and place as the board may determine which
meeting may be held in conjunction with an annual meeting of shareholders.

                                      -17-


ties register as the holder of one or more shares carrying the right to vote at
the meeting. Notice of a meeting of shareholders called for any purpose other
than consideration of the financial statements and auditor's report, election of
directors and reappointment of the incumbent auditor shall state the nature of
such business in sufficient detail to permit the shareholders to form a reasoned
judgement thereon and shall state the nature of any special business to be
transacted at the meeting.

     12.04 Record Date for Notice. The board may fix in advance a date,
preceding the date of any meeting of shareholders by not less than 21 nor more
than 50 days, as a record date for the determination of the shareholders
entitled to notice of the meeting, and notice of any such record date shall be
given not less than seven days before such record date, by newspaper
advertisement in the manner provided in the Act. If no record date is so fixed,
the record date for the determination of the shareholders entitled to receive
notice of the meeting shall be at the close of business on 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.

     12.05 List of Shareholders Entitled to Notice. For every meeting of
shareholders, the Corporation shall prepare a list of shareholders entitled to
receive notice of the meeting, arranged in alphabetical order and showing the
number of shares held by each shareholder entitled to vote at the meeting. If a
record date for the meeting is fixed pursuant to section 12.04, the shareholders
listed shall be those registered at the close of business on such record date.
If no record date is fixed, the shareholders listed shall be those registered at
the close of business on the day immediately preceding the day on which notice
of the meeting is given or, where no such notice is given, on the day on which
the meeting is held. The list shall be available for examination by any
shareholder during usual business hours at the registered office of the
Corporation or at the place where the central securities register is maintained
and at the meeting for which the list was prepared.

     12.06 Meetings Without Notice. A meeting of shareholders may be held
without notice at any time and place permitted by the Act:

     (a) if all the shareholders entitled to vote thereat are present in person
or duly represented or if those not present or represented waive notice of or
otherwise consent to such meeting being held; and

     (b) if the auditors and the directors are present or waive notice of or
otherwise consent to such meeting being held so long as such shareholders,
auditors or directors present are not attending for the express purpose of
objecting to the transaction of any business on the grounds that the meeting is
not lawfully called. At such a meeting, any business may be transacted which the
Corporation at a meeting of shareholders may transact. If the meeting is held at
a place outside Canada, shareholders not present or duly represented, but who
have


<PAGE>
                                      -18-


waived notice of or otherwise consented to such meeting, shall also be deemed to
have consented to the meeting being held at such place.

     12.07 Chairman, Secretary and Scrutineers. The chairman of any meeting of
shareholders shall be the first mentioned of such of the following officers as
have been appointed and who is present at the meeting: president, chairman of
the board, or a vice-president who is a shareholder. If no such officer is
present within 15 minutes from the time fixed for holding the meeting, the
persons present and entitled to vote shall choose one of their number to be
chairman. If the secretary of the Corporation is absent, the chairman shall
appoint some person, who need not be a shareholder, to act as secretary of the
meeting. If desired, one or more scrutineers, who need not be shareholders, may
be appointed by ordinary resolution or by the chairman with the consent of the
meeting.

     12.08 Persons Entitled to be Present. The only persons entitled to be
present at a meeting of shareholders shall be those entitled to vote thereat,
the directors and auditor of the Corporation and others who, although not
entitled to vote, are entitled or required under any provision of the Act or the
articles or by-laws to be present at the meeting. Any other person may be
admitted only on the invitation of the chairman of the meeting or with the
consent of the meeting.

     12.09 Quorum. Subject to the Act, a quorum for the transaction of business
at any meeting of shareholders shall be two persons present in person, or by
proxy and holding or representing by proxy, not less than 5% of the shares
entitled to vote at the meeting. If a quorum is present at the opening of any
meeting of shareholders, the shareholders present or represented may proceed
with the business of the meeting notwithstanding that a quorum is not present
throughout the meeting. If at the opening of the meeting a quorum is not
present, the meeting, if convened by a requisition of members, shall be
dissolved. In any other case, the shareholders present may adjourn the meeting
to a fixed time and place, but may not transact any other business, and the
shareholders personally present or represented by proxy at the adjourned meeting
shall constitute a quorum.

     12.10 Right to Vote. Every person named in the list referred to in section
12.05 shall be entitled to vote the shares shown thereon opposite his name at
the meeting to which such list relates except to the extent that:

     (a) where the Corporation has fixed a record date in respect of such
meeting, such person has transferred any of his shares after such record date,
or where the Corporation has not fixed a record date in respect of such meeting,
such person has transferred any of his shares after the date on which such list
is prepared; and

     (b) the transferee, having produced properly endorsed certificates
evidencing such shares or having otherwise established that he owns such shares,
has demanded not later


<PAGE>
                                      -19-


than 10 days before the meeting that his name be included in such list. In any
such excepted case the transferee shall be entitled to vote the transferred
shares at such meeting.

     12.11 Proxies. Every shareholder, including a shareholder that is a body
corporate, entitled to vote at a meeting of shareholders may by instrument in
writing appoint a proxyholder or alternate proxyholders, who need not be
shareholders, to attend and act at such meeting in the manner and to the extent
authorized by the proxy. Such instrument shall be signed by the shareholder or
his attorney authorized in writing, or if the shareholder is a body corporate,
under the hand of an officer or attorney thereof duly authorized. In addition to
the requirements of the Act, a proxy shall be in such form as the directors may
from time to time prescribe or in such other form as the chairman of the meeting
may accept. The board may specify in the notice calling the meeting a time, not
exceeding 48 hours (excluding non-business days), preceding the meeting, before
which proxies must be deposited with the Corporation or its agent. A proxy shall
be acted upon only if, prior to the time so specified, it shall be have been
deposited with the Corporation or an agent thereof specified in such notice or,
where no such time is specified in such notice, if it has been so deposited or
received by the secretary of the Corporation or by the chairman of the meeting
or any adjournment thereof prior to the time of voting. In addition to
revocation in any other manner permitted by law, a proxy may be revoked by an
instrument in writing executed in the same manner as a proxy and deposited
either at the registered office of the Corporation at any time up to and
including the last business day preceding the date of the meeting or with the
chairman of such meeting on the day of the meeting before any vote is cast under
its authority.

     12.12 Authorized Representative. Any shareholder which is a body corporate
or association may authorize by resolution of its directors or governing body an
individual to represent it at a meeting of shareholders and such individual may
exercise on the shareholder's behalf all the powers it could exercise if it were
an individual shareholder. The authority of such an individual shall be
established by depositing with the Corporation a certified copy of such
resolution, or in such other manner as may be satisfactory to the secretary of
the Corporation or the chairman of the meeting. Any such representative need not
be a shareholder.

     12.13 Joint Shareholders. If two or more persons hold shares jointly, any
one of them present in person or duly represented at a meeting of shareholders
may, in the absence of the other or others, vote the shares; but if two or more
of those persons are present in person or represented and vote, they shall vote
as one the shares jointly held by them.

     12.14 Votes to Govern. At a meeting of shareholders every question shall,
unless otherwise required by the articles or by-laws or by law, be determined by
a majority of the votes cast on the question. In case of an equality of votes
either upon a show of hands or upon a poll, the chairman of the meeting shall be
entitled to a second or casting vote.


<PAGE>
                                      -20-


     12.15 Show of Hands. Subject to the Act, any question at a meeting of
shareholders shall be decided by a show of hands, and unless a ballot thereon is
required or demanded as hereinafter provided, upon a show of hands every person
who is present and entitled to vote shall have one vote. Whenever a vote by show
of hands shall have been taken upon a question, unless a ballot thereon is so
required or demanded, a declaration by the chairman of the meeting that the vote
upon the question has been carried or carried by a particular majority or not
carried, and an entry to that effect in the minutes of the meeting shall be
prima facie evidence of the fact without proof of the number or proportion of
the votes recorded in favour of or against any resolution or other proceeding in
respect of the said question, and the result of the vote so taken shall be the
decision of the shareholders upon the said question.

     12.16 Ballots. On any question proposed for consideration at a meeting of
shareholders, and whether or not a show of hands has been taken thereon, the
chairman may require a ballot or any person who is present and entitled to vote
on such question at the meeting may demand a ballot. A ballot so required or
demanded shall be taken in such manner as the chairman shall direct. A
requirement or demand for a ballot may be withdrawn at any time prior to the
taking of the ballot. If a ballot is taken each person present shall be
entitled, in respect of the shares which he is entitled to vote at the meeting
upon the question, to that number of votes provided by the Act or the articles,
and the result of the ballot so taken shall be the decision of the shareholders
upon the said question.

     12.17 Resolution need not be seconded. No resolution proposed at a meeting
need be seconded and the chairman of any meeting (provided he is entitled to
vote) shall be entitled to move or second a resolution without relinquishing the
chair.

     12.18 Adjournment. The chairman at a meeting of shareholders may, with the
consent of the meeting and subject to such conditions as the meeting may decide,
adjourn the meeting from time to time and from place to place. If a meeting of
shareholders is adjourned for less than 30 days, it shall not be necessary to
give notice of the adjourned meeting, other than by announcement at the earliest
meeting that it is adjourned. Subject to the Act, if a meeting of shareholders
is adjourned by one or more adjournments for an aggregate of 30 days or more,
notice of the adjourned meeting shall be given as for an original meeting.


                                Section Thirteen

                                     NOTICES


     13.01 Method of Giving Notices. Any notice (which term includes any
communication or document) to be given (which term includes sent, delivered or
served) pur-


<PAGE>
                                      -21-


suant to the Act, the regulations thereunder, the articles, the by-laws or
otherwise to a shareholder, director, officer, auditor, member of a committee of
the board or member of an advisory body shall be sufficiently given if delivered
personally to the person to whom it is to be given or to his recorded address or
if mailed to him by prepaid ordinary mail or sending it by telegram, telex,
telefax, telecommunication device or other similar form of communication to his
recorded address. A notice so delivered shall be deemed to have been received
when it is delivered personally or to the recorded address as aforesaid; a
notice so mailed shall be deemed to have been received at the time it would have
been delivered in the ordinary course of the mail, unless there are reasonable
grounds for believing it was not received at all; a notice sent by telegram,
telex, telefax, telecommuncation device or other similar form of communication
shall be deemed to have been given or made on the day following the day it was
sent. The secretary may change or cause to be changed the recorded address of
any shareholder, director, officer, auditor or member of a committee of the
board in accordance with any information believed by him to be reliable.

     13.02 Notice to Joint Shareholders. If two or more persons are registered
as joint holders of any share, any notice may be addressed to all such joint
holders but notice addressed to one of such persons shall be sufficient notice
to all of them.

     13.03 Computation of Time. In computing the date when notice must be given
under any provision requiring a specified number of days' notice of any meeting
or other event, the date of giving the notice shall be excluded and the date of
the meeting or other event shall be included.

     13.04 Undelivered Notices. If any notice given to a shareholder pursuant to
section 13.01 is returned on three consecutive occasions because he cannot be
found, the Corporation shall not be required to give any further notices to such
shareholder until he informs the Corporation in writing of his new address.

     13.05 Omission and Errors. The accidental omission to give any notice to
any shareholder, director, officer, auditor or member of a committee of the
board or the non-receipt of any notice by any such person or any error in any
notice not affecting the substance thereof shall not invalidate any action taken
at any meeting held pursuant to such notice or otherwise founded thereon.

     13.06 Unregistered Shareholders. Every person who becomes entitled to any
share by any means whatsoever shall be bound by every notice in respect of such
share which shall have been duly given to the shareholder from whom he derives
his title to such share prior to his name and address being entered on the
securities register (whether such notice was given before or after the happening
of the event upon which he became so entitled) and prior to his furnishing to
the Corporation the proof of authority of his entitlement prescribed by the Act.


<PAGE>
                                      -22-


     13.07 Waiver of Notice. Any shareholder, proxyholder, other person entitled
to attend a meeting of shareholders, director, officer, auditor, member of a
committee of the board or member of an advisory body may at any time waive any
notice, or waive or abridge the time for any notice, required to be given to him
under the Act, the regulations thereunder, the articles, the by-laws or
otherwise and such waiver or abridgement, whether given before or after the
meeting or other event of which notice is required to be given, as the case may
be. Any such waiver or abridgement shall be in writing, except a waiver of
notice of a meeting of shareholders of the board, a committee of the board or an
advisory body, which may be given in any manner.

               "THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE

               BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE

     (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note shall be
reduced accordingly and an endorsement shall be made on such Global Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note shall be increased accordingly
and an endorsement shall be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

     (i) General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Company
     shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon the Company's order or at the Registrar's request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any


<PAGE>
                                      -46-


     such transfer taxes or similar governmental charge payable upon exchange or
     transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05
     hereof).

          (iii) The Registrar shall not be required to register the transfer of
     or exchange any Note selected for redemption in whole or in part, except
     the unredeemed portion of any Note being redeemed in part.

          (iv) All Global Notes and Definitive Notes issued upon any
     registration of transfer or exchange of Global Notes or Definitive Notes
     shall be the valid obligations of the Company, evidencing the same debt,
     and entitled to the same benefits under this Indenture, as the Global Notes
     or Definitive Notes surrendered upon such registration of transfer or
     exchange.

          (v) The Company shall not be required (A) to issue, to register the
     transfer of or to exchange any Notes during a period beginning at the
     opening of business 15 days before the day of any selection of Notes for
     redemption under Section 3.02 hereof and ending at the close of business on
     the day of selection, (B) to register the transfer of or to exchange any
     Note so selected for redemption in whole or in part, except the unredeemed
     portion of any Note being redeemed in part or (C) to register the transfer
     of or to exchange a Note between a record date and the next succeeding
     Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of
     any Note, the Trustee, any Agent and the Company may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of and interest on
     such Notes and for all other purposes, and none of the Trustee, any Agent
     or the Company shall be affected by notice to the contrary.

          (vii) The Trustee shall authenticate Global Notes and Definitive Notes
     in accordance with the provisions of Section 2.02 hereof.

          (viii) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.06 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

Section 2.07. Replacement Notes.

     If any mutilated Note is surrendered to the Trustee or the Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Com-


<PAGE>
                                      -47-


pany, an indemnity bond must be supplied by the Holder that is sufficient in the
judgment of the Trustee and the Company to protect the Company, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer if
a Note is replaced. The Company may charge for its expenses in replacing a Note.

     Every replacement Note is an additional obligation of the Company and shall
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

Section 2.08. Outstanding Notes.

     The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section as
not outstanding. Except as set forth in Section 2.09 hereof, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note; however, Notes held by the Company or a Subsidiary of the Company
shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof. If
a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Note is
held by a bona fide purchaser.

     If the principal amount of any Note is considered paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue.

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes shall
be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.09. Treasury Notes.

     In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that a Responsible Officer of the Trustee knows are so owned shall be
so disregarded.

Section 2.10. Temporary Notes.

     Until certificates representing Notes are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form
of certificated Notes but may have variations that the Company considers
appropriate for temporary Notes and as shall be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company shall prepare and the Trustee
shall authenticate definitive Notes in exchange for temporary Notes.

     Holders of temporary Notes shall be entitled to all of the benefits of this
Indenture.

Section 2.11. Cancellation.

     The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes in accordance with its customary procedures. The Company may not
issue new Notes to replace Notes that it has paid or that have been delivered to
the Trustee for cancellation.

Section 2.12. Defaulted Interest.

     If the Company defaults in a payment of interest on the Notes, it shall pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

                            REDEMPTION AND PREPAYMENT


Section 3.01. Notices to Trustee.

     If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 30
days but not more than 60 days before a redemption date, an Officers'
Certificate setting forth (i) the clause of this Indenture pursuant to which the
redemption shall occur, (ii) the redemption date, (iii) the principal amount of
Notes to be redeemed and (iv) the redemption price.

Section 3.02. Selection of Notes to Be Redeemed.

     If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee shall select the Notes to be redeemed or
purchased among the Holders of the Notes:

          (a) if the Notes are listed, in compliance with the requirements of
     the principal national securities exchange on which the Notes are listed;
     or

          (b) if the Notes are not so listed, on a pro rata basis, by lot or in
     accordance with any other method as the Trustee shall deem fair and
     appropriate. In the event of partial redemption by lot, the particular
     Notes to be redeemed shall be selected, unless otherwise provided herein,
     not less than 30 nor more than 60 days prior to the redemption date by the
     Trustee from the outstanding Notes not previously called for redemption.

     The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

     Subject to the provisions of Section 3.09 hereof, at least 30 days but not
more than 60 days before a redemption date, the Company shall mail or cause to
be mailed, by first class


<PAGE>
                                      -50-


mail, a notice of redemption to each Holder whose Notes are to be redeemed at
its registered address.

     The notice shall identify the Notes to be redeemed and shall state:

          (a) the redemption date;

          (b) the redemption price;

          (c) if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the redemption
     date upon surrender of such Note, a new Note or Notes in principal amount
     equal to the unredeemed portion shall be issued upon cancellation of the
     original Note;

          (d) the name and address of the Paying Agent;

          (e) that Notes called for redemption must be surrendered to the Paying
     Agent to collect the redemption price;

          (f) that, unless the Company defaults in making such redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the redemption date;

          (g) the paragraph of the Notes and/or Section of this Indenture
     pursuant to which the Notes called for redemption are being redeemed; and

          (h) that no representation is made as to the correctness or accuracy
     of the CUSIP number, if any, listed in such notice or printed on the Notes.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
shall have delivered to the Trustee, at least 45 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Notes called for redemption become irrevocably due and payable on the redemption
date at the redemption price. A notice of redemption may not be conditional.

Section 3.05. Deposit of Redemption Price.

     At or prior to 10:00 a.m., New York City time, on the redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money sufficient
to pay the redemption price of and accrued interest on all Notes to be redeemed
on that date. The Trustee or the Paying Agent shall promptly return to the
Company any money deposited with the Trustee or the Paying Agent by the Company
in excess of the amounts necessary to pay the redemption price of, and accrued
interest on, all Notes to be redeemed.

     If the Company complies with the provisions of the preceding paragraph, on
and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Company to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until
such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Notes and in
Section 4.01 hereof.

Section 3.06. Notes Redeemed in Part.

     Upon surrender of a Note that is redeemed in part, the Company shall issue
and, upon the Company's written request, the Trustee shall authenticate for the
Holder at the expense of the Company a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

Section 3.07. Optional Redemption.

issued under this Indenture at a redemption price of 112% of the principal
amount thereof, plus accrued and unpaid interest, if any, thereon to the
redemption date, with the net cash proceeds of one or more Qualified Equity
Offerings; provided that:

          (i) at least 65% of the sum of (a) the aggregate principal amount of
     Notes originally issued under the Indenture and (b) the total amount of
     Additional Senior Notes issued under the Indenture remains outstanding
     immediately after the occurrence of any such redemption (excluding Notes
     held by the Company and its Subsidiaries); and

          (ii) the redemption must occur within 90 days of the date of the
     closing of such Qualified Equity Offering.

     (c) Notwithstanding the provisions of clause (a) of this Section 3.07, the
Company may redeem the Notes in the event the Company becomes obligated to pay
any Additional Amounts as a result of a change in the laws or regulations of
Canada or any Canadian Taxing Authority, or a change in any official position
regarding the application or interpretation thereof, which is publicly announced
or becomes effective on or after the Issue Date. Upon the occurrence of any such
change, the Company may, at any time, redeem all, but not part, of the Notes at
a price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date.

the provisions of Section 3.01 through 3.06 hereof.

<PAGE>
                                      -53-

Section 4.10 hereof (the "Offer Amount") or, if less than the Offer Amount has
been tendered, all Notes tendered in response to the Asset Sale Offer. Payment
for any Notes so purchased shall be made in the same manner as interest payments
are made.

     If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

     Upon the commencement of an Asset Sale Offer the Company shall send, by

     accepted for payment pursuant the Asset Sale Offer shall cease to accrue
     interest after the Purchase Date;

          (e) that Holders electing to have a Note purchased pursuant to an
     Asset Sale Offer may elect to have Notes purchased in integral multiples of
     $1,000 only;

          (f) that Holders electing to have a Note purchased pursuant to any
     Asset Sale Offer shall be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Note
     completed, or transfer by book-entry transfer, to the Company, a
     depositary, if appointed by the Company, or a Paying Agent at the address
     specified in the notice at least three days before the Purchase Date;

          (g) that Holders shall be entitled to withdraw their election if the
     Company, the depositary or the Paying Agent, as the case may be, receives,
     not later than the ex-

     letter setting forth the name of the Holder, the principal amount of the
     Note the Holder delivered for purchase and a statement that such Holder is
     withdrawing his election to have such Note purchased;

          (h) that, if the aggregate principal amount of Notes surrendered by
     Holders exceeds the Offer Amount, the Company shall select the Notes to be
     purchased on a pro rata basis (with such adjustments as may be deemed
     appropriate by the Company so that only Notes in denominations of $1,000,
     or integral multiples thereof, shall be purchased); and

          (i) that Holders whose Notes were purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

     On or before the Purchase Date, the Company shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer or
if less than the Offer Amount has been tendered, all Notes tendered, and shall
deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as
the case may be, shall promptly (but in any case not later than five days after
the Purchase Date) mail or deliver to each tendering Holder an amount equal to
the purchase price of the Notes tendered by such Holder and accepted by the
Company for purchase, and the Company shall promptly issue a new Note, and the
Trustee, upon written request from the Company shall authenticate and mail or
deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

     Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

                                    COVENANTS


Section 4.01. Payment of Notes.

     The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Company or a Subsidiary thereof,
holds as of 10:00 a.m. New York City time on the due date money deposited by the
Company in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due. The Company shall pay all
Additional Interest, if any, in the same manner on the dates and in the amounts
set forth in the Registration Rights Agreement. Whenever in this Indenture there
is mentioned, in any context, the payment of principal, premium, if any,
redemption price, Change of Control Payment, offer price and interest, or any
other amount payable under or with respect to any Note, such mention shall be
deemed to include mention of the payment of Additional Amounts to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof.

     The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful; it shall pay interest (including postpetition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

Section 4.02. Maintenance of Office or Agency.

     The Company shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an affiliate
of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be served. The
Company shall give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may


<PAGE>
                                      -56-


from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, the City
of New York for such purposes. The Company shall give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

     The Company hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Company in accordance with Section 2.03.

Section 4.03. Reports.

     Whether or not required by the rules and regulations of the SEC, for so
long as any Notes remain outstanding, the Company shall furnish to the Holders
the information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act. Whether or not the Company is subject to Section 13(a) or 15(d)
of the Exchange Act, the Company shall file with the SEC and furnish to the
Holders and the Trustee (i) within 140 days after the end of each fiscal year,
annual reports on Form 20-F or 40-F, as applicable (or any successor form),
containing the information required to be contained therein (or required in such
successor form) and (ii) (a) within 45 days after the end of each of the first
three fiscal quarters of each fiscal year, reports on Form 10-Q or (b) within 60
days after the end of each of the first three fiscal quarters of each fiscal
year, reports on Form 6-K (or any successor form) which, regardless of
applicable requirements, shall, at a minimum, contain a "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

Section 4.04. Compliance Certificate.

     (a) The Company shall deliver to the Trustee, within 90 days after the end
of each fiscal year, an Officers' Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture, including without limitation the obligations set forth in
Section 4.07, and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of his or
her knowledge no event has occurred and remains in existence by reason of which
payments on account of the principal of or interest, if any, on the Notes is
prohibited or if such event has occurred, a description of the event and what
action the Company is taking or proposes to take with respect thereto.

                                      -57-


     (b) So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by a
written statement of the Company's independent public accountants (who shall be
a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation. In the
event that, after the Company has used its reasonable best efforts to obtain the
written statement of the Company's independent public accountants required by
the provisions of this paragraph, such statement cannot be obtained, the Company
shall deliver, in satisfaction of its obligations under this Section 4.04, an
Officers' Certificate (A) certifying that it has used its reasonable best
efforts to obtain such required statement but was unable to do so and (B)
attaching the written statement of the Company's accountants that the Company
received in lieu thereof.

     (c) The Company shall, so long as any of the Notes are outstanding, deliver
to the Trustee, forthwith upon any Officer becoming aware of any Default or
Event of Default, an Officers' Certificate specifying such Default or Event of
Default and what action the Company is taking or proposes to take with respect
thereto.

Section 4.05. Taxes; Payment of Additional Amounts.

     The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies
except such as are contested in good faith and by appropriate proceedings or
where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

     All payments made by or on behalf of the Company on or with respect to the
Notes shall be made without withholding or deduction for any Taxes imposed by
any Canadian Taxing Authority, unless required by law or the interpretation or
administration thereof by the relevant Taxing Authority. If the Company or any
other payor is required to withhold or deduct any amount on account of Taxes
from any payment made on or with respect to the Notes, the Company shall:

          (a) make such withholding or deduction;

          (b) remit the full amount deducted or withheld to the relevant
     government authority in accordance with applicable law;


<PAGE>
                                      -58-


          (c) pay such additional amounts ("Additional Amounts") as may be
     necessary so that the net amount received by each Holder (including
     Additional Amounts) after such withholding or deduction shall not be less
     than the amount the Holder would have received if such Taxes had not been
     withheld or deducted;

          (d) furnish to the Holders, within 30 days after the date the payment
     of any Taxes is due, certified copies of tax receipts evidencing such
     payment by the Company;

          (e) indemnify and hold harmless each Holder (other than an Excluded
     Holder) for the amount of (i) any Taxes paid by such Holder as a result of
     payments made on or with respect to the Notes, (ii) any liability
     (including penalties, interest and expenses) arising therefrom or with
     respect thereto and (iii) any Taxes imposed with respect to any
     reimbursement under (i) or (ii), but excluding any such Taxes on such
     Holder's net income; and

          (f) at least 30 days prior to each date on which any Additional
     Amounts are payable, deliver to the Trustee an Officers' Certificate
     stating the amounts so payable and such other information necessary to
     enable the Trustee to pay such Additional Amounts to Holders on the payment
     date.

     Notwithstanding the foregoing, no Additional Amounts shall be payable to a
Holder in respect of a beneficial owner of a Note (an "Excluded Holder"):

          (a) with which the Company does not deal at arm's length (within the
     meaning of the Income Tax Act (Canada)) at the time of making such payment;
     or

          (b) which is subject to such Taxes by reason of its being connected
     with Canada or any province or territory thereof otherwise than by the mere
     acquisition, holding or disposition of Notes or the receipt of payments
     thereunder.

     The obligation of the Company to make payments of Additional Amounts
pursuant to this Section 4.05 shall survive any termination of this Indenture or
the defeasance of any rights under this Indenture.

Section 4.06. Stay, Extension and Usury Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any


<PAGE>
                                      -59-


such law, and covenants that it shall not, by resort to any such law, hinder,
delay or impede the execution of any power herein granted to the Trustee, but
shall suffer and permit the execution of every such power as though no such law
has been enacted.

Section 4.07. Restricted Payments.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly:

          (a) declare or pay any dividend or make any other payment or
     distribution on account of the Company's or any of its Restricted
     Subsidiaries' Equity Interests (including, without limitation, any payment
     in connection with any merger or consolidation involving the Company or any
     of its Restricted Subsidiaries) or to the direct or indirect holders of the
     Company's or any of its Restricted Subsidiaries' Equity Interests in their
     capacity as such (other than dividends or distributions payable in Equity
     Interests (other than Disqualified Stock) of the Company or to the Company
     or a Restricted Subsidiary of the Company);

          (b) purchase, redeem or otherwise acquire or retire for value
     (including, without limitation, in connection with any merger or
     consolidation involving the Company) any Equity Interests of the Company or
     any direct or indirect parent of the Company or any Restricted Subsidiary
     of the Company (other than any such Equity Interests owned by the Company
     or any Restricted Subsidiary of the Company);

          (c) make any payment on or with respect to, or purchase, redeem,
     defease or otherwise acquire or retire for value any Indebtedness that is
     subordinated to the Notes, except a payment of interest or principal at the
     Stated Maturity thereof; or

          (d) make any Restricted Investment (all such payments and other
     actions set forth in clauses (a) through (d) above being collectively
     referred to as "Restricted Payments"),

     unless:

          (a) at the time of and after giving effect to such Restricted Payment,
     no Default or Event of Default shall have occurred and be continuing or
     would occur as a consequence thereof; and

          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least

                                      -60-


     $1.00 of additional Indebtedness pursuant to clause (i) or (ii) of the
     first paragraph of Section 4.09; and

          (c) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company and its Restricted
     Subsidiaries after the Issue Date (excluding Restricted Payments permitted
     by clauses (b), (c), (d), (f), (g), (h)(i), (i), (j), (k), (l) and (m)) is
     less than the sum, without duplication, of

               (i) 50% of the Consolidated Net Income of the Company for the
          period (taken as one accounting period) from the beginning of the
          first fiscal quarter commencing after the Issue Date to the end of the
          Company's most recently ended fiscal quarter for which internal
          financial statements are available at the time of such Restricted
          Payment (or, if such Consolidated Net Income for such period is a
          deficit, less 100% of such deficit), plus

               (ii) 100% of the aggregate net cash proceeds received by the
          Company since the Issue Date as a contribution to its common equity
          capital or from the issue or sale of Equity Interests of the Company

          convertible or exchangeable Disqualified Stock or convertible or
          exchangeable debt securities of the Company that have been converted
          into or exchanged for such Equity Interests (other than Equity
          Interests (or Disqualified Stock or debt securities) sold to a
          Subsidiary of the Company), plus the aggregate net cash proceeds
          received by the Company upon any such conversion or exchange, plus

               (iii) 100% of the net reduction in Investments on and after the
          Issue Date, resulting from payments of interest on Indebtedness,
          dividends, repayments of loan or advances, or other transfers of
          property (but only to the extent such interest, dividends, repayments
          or other transfers of property are not included in the calculation of
          Consolidated Net Income), in each case to the Company or any of its
          Restricted Subsidiaries from any Person (including, without
          limitation, from Unrestricted Subsidiaries of the Company) or from
          redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
          (in each case, valued as provided in the definition of "Investments"),
          not to exceed in the case of any Person the amount of Restricted
          Investments previously made by the Company or any of its Restricted
          Subsidiaries in such Unrestricted Subsidiary (subsequent to the Issue
          Date) and in each such case which was treated as a Restricted Payment
          (other than any such Restricted Payment that was made pursuant to the
          provisions of paragraph (a) through (m) below).

          acquisition of any subordinated Indebtedness of the Company or of any
          Equity Interests of the Company or any Restricted Subsidiary in
          exchange for, or out of the net cash proceeds of the substantially
          concurrent sale (other than to a Subsidiary of the Company) of, Equity
          Interests of the Company (other than Disqualified Stock); provided
          that the amount of any such net cash proceeds that are utilized for

          Investments shall own at least 20% of the Voting Stock of such Person;

               (g) Permitted Fiber Investments in Telecommunications Assets;

pursuant to the Restricted Payment. The fair market value of any assets or
securities that are required to be valued by this covenant shall be determined
by the Board of Directors whose resolution with respect thereto shall be
delivered to the Trustee. The Board of Directors' determination must be based
upon an opinion or appraisal issued by an accounting, appraisal or investment
banking firm of national standing if the fair market value exceeds $15.0

Payment made pursuant to clause (g) above. In any year in which the Company
makes one or more Restricted Payments, the Company shall include in its
compliance certificate to the Trustee pursuant to Section 4.04 hereof, a
certification stating that all such Restricted Payments are, or were, permitted
by this Indenture and shall set forth the basis upon which the calculations
required by this Section 4.07 were computed, together with a copy of any
fairness opinion or appraisal required hereby.

Section 4.08. Dividend and Other Payment Restrictions Affecting Subsidiaries.

     The Company shall not, and shall not permit any of its Restricted

          Stock to the Company or any of the Company's Restricted Subsidiaries,
          or with respect to any other interest or participation in, or measured
          by, its profits, or pay any Indebtedness owed to the Company or any of
          the Company's Restricted Subsidiaries;

               (b) make loans or advances to the Company or any of the Company's

               (c) transfer any of its properties or assets to the Company or

     However, the preceding restrictions shall not apply to encumbrances or
restrictions existing under or by reason of:

               (a) Existing Indebtedness as in effect on the Issue Date and any
          amendments, modifications, restatements, renewals, increases,
          supplements, refundings, replacements or refinancings thereof,
          provided that such amendments, modifications, restatements, renewals,
          increases, supplements, refundings, replacement or refinancings are no
          more restrictive, taken as a whole, with respect to such dividend and
          other payment restrictions than those contained in such Existing
          Indebtedness, as in effect on the Issue Date;

                                      -64-


               (b) the Credit Facilities, this Indenture, the Notes and the
          Exchange Notes, Qualified Subsidiary Indebtedness and Indebtedness
          ranking pari passu with the Notes; provided that with respect to
          Indebtedness ranking pari passu with the Notes such provisions are no
          more restrictive than those set forth in the Notes;

               (c) applicable law;

               (d) any instrument governing Indebtedness or Capital Stock of a
          Person acquired by the Company or any of its Restricted Subsidiaries
          as in effect at the time of such acquisition (except to the extent
          such Indebtedness was incurred in connection with or in contemplation
          of such acquisition), which encumbrance or restriction is not
          applicable to any Person, or the properties or assets of any Person,
          other than the Person, or the property or assets of the Person, so
          acquired, provided that, in the case of Indebtedness, such
          Indebtedness was permitted by the terms of the Indenture to be
          incurred;

               (e) customary non-assignment provisions restricting subletting or
          assignment in leases or other agreements entered into in the ordinary
          course of business and consistent with past practices;

               (f) purchase money obligations for property acquired in the
          ordinary course of business that impose restrictions on the property
          so acquired of the nature described in clause (c) of the preceding
          paragraph;

               (g) any agreement for the sale or other disposition of a
          Restricted Subsidiary that restricts distributions by such Restricted
          Subsidiary pending its sale or other disposition, provided that the
          consummation of such transaction would not result in a Default or an
          Event of Default, that such restriction terminates if such transaction
          is not consummated and that the consummation or abandonment of such
          transaction occurs within one year of the date such agreement was
          entered into;

               (h) Permitted Refinancing Indebtedness, provided that the
          restrictions contained in the agreements governing such Permitted
          Refinancing Indebtedness are no more restrictive, taken as a whole,
          than those contained in the agreements governing the Indebtedness
          being refinanced;

               (i) Liens securing Indebtedness otherwise permitted to be
          incurred pursuant to the provisions of Section 4.12 that limit the
          right of the Company or any of its Restricted Subsidiaries to dispose
          of the assets subject to such Lien;


<PAGE>
                                      -65-


               (j) customary limitations on the disposition or distribution of

          agreements entered into in the ordinary course of business; and

               (k) restrictions on cash or other deposits or net worth imposed
          by customers under contracts entered into in the ordinary course of
          business.

               (l) encumbrances and restrictions in Indebtedness incurred by
          Foreign Subsidiaries in accordance with Section 4.09; and

               (m) any Indebtedness or any agreement pursuant to which such
          Indebtedness was issued if (A) the encumbrance or restriction applies
          only upon a payment or financial covenant default or event of default
          contained in such Indebtedness or agreement and (B) the encumbrance or
          restriction is not materially more disadvantageous to the Holders of
          the Notes than is customary in comparable financings (as determined in
          good faith by the Board of Directors of the Company).

Section 4.09. Incurrence of Indebtedness and Issuance of Preferred Stock.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt), and the Company shall not issue any Disqualified Stock and shall not
permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; provided, however, that the Company may incur Indebtedness (including
Acquired Debt) and issue Disqualified Stock and any Restricted Subsidiary may
incur Acquired Debt, if either:

          (i) the Consolidated Leverage Ratio at the end of the Company's most
     recently ended full fiscal quarter (the "Reference Period") for which a
     consolidated balance sheet of the Company is available immediately
     preceding the date on which such additional Indebtedness is incurred or
     such Disqualified Stock is issued would have been less than 5.5 to 1.0,
     determined on a pro forma basis (including a pro forma application of the
     net proceeds therefrom), as if the additional Indebtedness had been
     incurred, or the Disqualified Stock had been issued, as the case may be, at
     the beginning of the Reference Period; or

          (ii) the Consolidated Capital Ratio at the end of the Reference Period
     would have been less than 2.0 to 1.0, determined after giving effect to the
     incurrence or issuance of such Indebtedness or Disqualified Stock and, to
     the extent set forth in the definitions used herein, on a pro forma basis
     (including, to the extent set forth in the definitions used herein, a pro
     forma application of the net proceeds therefrom).


<PAGE>
                                      -66-


     The first paragraph of this Section 4.09 shall not prohibit the incurrence
of any of the following items of Indebtedness (collectively, "Permitted Debt"):

          (a) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness under Credit Facilities or Permitted Vendor
     Facilities; provided that the aggregate principal amount of all
     Indebtedness of the Company and its Restricted Subsidiaries outstanding
     under all Credit Facilities or Permitted Vendor Facilities after giving
     effect to such incurrence (with letters of credit being deemed to have a
     principal amount equal to the maximum potential liability of the Company
     thereunder) does not exceed an amount equal to $200.0 million less the
     aggregate amount of all Net Proceeds of Asset Sales applied by the Company
     or any of its Restricted Subsidiaries since the Issue Date to permanently
     repay Indebtedness under a Credit Facility pursuant to Section 4.10 hereof;

          (b) the incurrence by the Company and its Restricted Subsidiaries of
     Existing Indebtedness;

          (c) the incurrence by the Company of Indebtedness represented by the
     Notes and the Exchange Notes;

          (d) the incurrence by the Company or any of its Restricted
     Subsidiaries of Purchase Money Indebtedness and Vendor Financing
     Indebtedness provided (A) that the amount thereof does not exceed 100% of
     the Company's and its Restricted Subsidiaries' aggregate cost (determined
     in accordance with GAAP in good faith by the Board of Directors) of the
     construction, acquisition, development, engineering, installation and
     improvement of the applicable Telecommunications Assets and (B) in the case
     of the incurrence of either Purchase Money Indebtedness or Vendor Financing
     Indebtedness by a Restricted Subsidiary, such Indebtedness shall be
     Qualified Subsidiary Indebtedness;

          (e) the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace,
     Indebtedness (other than intercompany Indebtedness) that was permitted by
     this Indenture to be incurred under the first paragraph of this Section or
     clauses (b), (c), (d), (l), (n), (o) or (p) of this paragraph;

          (f) the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries and the issuance of preferred stock by a
     Restricted Subsidiary to the Company or another Restricted Subsidiary of
     the Company; provided, however, that:


<PAGE>
                                      -67-


               (i) if the Company is the obligor on such Indebtedness, such
          Indebtedness must be expressly subordinated to the prior payment in
          full in cash of all Obligations with respect to the Notes; and

               (ii) (A) any subsequent issuance or transfer of Equity Interests
          that results in any such Indebtedness or preferred stock being held by
          a Person other than the Company or a Restricted Subsidiary thereof and
          (B) any sale or other transfer of any such Indebtedness or preferred
          stock to a Person that is not either the Company or a Restricted
          Subsidiary thereof; shall be deemed, in each case, to constitute an
          incurrence of such Indebtedness by the Company or such Restricted
          Subsidiary, as the case may be, that was not permitted by this clause
          (f);

          (g) the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     fixing or hedging interest or foreign currency exchange rate risk with
     respect to any floating rate Indebtedness or foreign currency based
     Indebtedness, respectively, that is permitted by the terms of this
     Indenture to be outstanding; provided that the notional amount of any such
     Hedging Obligation does not exceed the amount of Indebtedness or other
     liability to which such Hedging Obligation relates;

          (h) the guarantee by the Company or any of its Restricted Subsidiaries
     of Indebtedness of the Company or any Restricted Subsidiary of the Company
     that was permitted to be incurred by another provision of this covenant;

          (i) the accrual of interest, accretion or amortization of original
     issue discount, the payment of interest on any Indebtedness in the form of
     additional Indebtedness with the same terms, and the payment of dividends
     on Disqualified Stock in the form of additional shares of the same class of
     Disqualified Stock; provided, in each such case, that the amount thereof is
     included in Fixed Charges of the Company as accrued;

          (j) the Company and its Restricted Subsidiaries may incur Indebtedness
     solely in respect of bankers acceptances, letters of credit and performance
     bonds or similar arrangements, all in the ordinary course of business
     (other than to the extent not supporting Indebtedness);

          (k) the incurrence by the Company or any of its Restricted
     Subsidiaries arising from agreements of the Company or any of its
     Restricted Subsidiaries providing for indemnification, adjustment of
     purchase price, earn out or other similar obligation, in each case,
     incurred or assumed in connection with the disposition of any business,
     assets or Restricted Subsidiary of the Company or any of its Restricted
     Subsidi-


<PAGE>
                                      -68-


     aries, other than guarantees of Indebtedness incurred by any Person
     acquiring all or any portion of such business, assets or Restricted
     Subsidiary for the purpose of financing such acquisition;

          (l) the incurrence of Indebtedness by Foreign Subsidiaries not to
     exceed $10.0 million (or the equivalent amount thereof, in other foreign
     currencies);

          (m) the Company or any of its Restricted Subsidiaries may incur
     Permitted ROW Indebtedness;

          (n) the incurrence by the Company or any of its Restricted
     Subsidiaries of Acquired Debt in an aggregate amount not to exceed $10.0
     million at any time outstanding;

          (o) Indebtedness of the Company not to exceed, at any one time
     outstanding, two times the net cash proceeds received by the Company after
     the Issue Date from the issuance and sale of its Equity Interest (other
     than Disqualified Stock) to a Person that is not a Subsidiary of the
     Company, to the extent such net cash proceeds have not been used pursuant
     to (i) clause (c)(ii) of the first paragraph of Section 4.07 or (ii)
     clauses (b) or (d) of the second paragraph of Section 4.07 to make a
     Restricted Payment; and

          (p) the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) at any time outstanding not to exceed
     $15.0 million.

     Indebtedness or preferred stock of any Person which is outstanding at the
time such Person becomes a Restricted Subsidiary of the Company (including upon
designation of any Subsidiary or other Person as a Restricted Subsidiary) or is
merged with or into or consolidated with the Company or a Restricted Subsidiary
of the Company shall be deemed to have been incurred at the time such Person
becomes such a Restricted Subsidiary of the Company or is merged with or into or
consolidated with the Company or a Restricted Subsidiary of the Company, as
applicable.

     Notwithstanding any other provisions of this Section 4.09, the maximum
amount of Indebtedness that the Company or a Restricted Subsidiary may incur
shall not be deemed to be exceeded solely as a result of fluctuations in the
exchange rates of currencies.

     For purposes of determining compliance with this Section 4.09, in the event
that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (a) through (p) above, or is
entitled to be incurred pursuant to


<PAGE>
                                      -69-


the first paragraph of this covenant, the Company shall be permitted to classify
such item of Indebtedness on the date of its incurrence in any manner that
complies with this Section 4.09.

Section 4.10. Limitation on Asset Sales.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

          (a) the Company (or the Restricted Subsidiary, as the case may be)
     receives consideration at the time of such Asset Sale at least equal to the
     fair market value of the assets or Equity Interests issued or sold or
     otherwise disposed of;

          (b) such fair market value is determined by the Company's Board of
     Directors and evidenced by a resolution of the Board of Directors set forth
     in an Officers' Certificate delivered to the Trustee; and

          (c) at least 75% of the consideration therefor received by the Company
     or such Restricted Subsidiary is in the form of cash or Telecommunications
     Assets. For purposes of this provision, each of the following shall be
     deemed to be cash:

               (i) any liabilities (as shown on the Company's or such Restricted
          Subsidiary's most recent balance sheet), of the Company or any
          Restricted Subsidiary (other than contingent liabilities and
          liabilities that are by their terms subordinated to the Notes) that
          are assumed by the transferee of any such assets pursuant to a
          customary novation agreement that releases the Company or such
          Restricted Subsidiary from further liability; and

               (ii) any securities, notes or other obligations received by the
          Company or any such Restricted Subsidiary from such transferee that
          are within 180 days converted by the Company or such Restricted
          Subsidiary into cash (to the extent of the cash received in that
          conversion).

     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company or such Restricted Subsidiary, as applicable, may apply such Net
Proceeds at its option:

     (a) to permanently repay or retire

          (i) secured Indebtedness of the Company, including Indebtedness under
     Credit Facilities,

          (ii) Indebtedness of the Company that ranks equally with the Notes but
     has a maturity date that is prior to the maturity date of the Notes, or


<PAGE>
                                      -70-


          (iii) Indebtedness of any Restricted Subsidiary of the Company (in
     each case other than any Indebtedness owed to the Company or any Restricted
     Subsidiary); or

     (b) to acquire Telecommunications Assets.

Pending the final application of any such Net Proceeds, the Company may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph shall constitute Excess Proceeds. When the
aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall
make an Asset Sale Offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets to purchase the maximum principal amount of
Notes and such other pari passu Indebtedness that may be purchased out of the
Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100%
of principal amount plus accrued and unpaid interest, if any, thereon to the
date of purchase and shall be payable in cash. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, the Company may use such Excess
Proceeds for any purpose not otherwise prohibited by this Indenture. If the
aggregate principal amount of Notes and such other pari passu Indebtedness
tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes and such other pari passu Indebtedness to be
purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero.

Section 4.11. Transactions with Affiliates.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties, assets or securities to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

          (a) such Affiliate Transaction is on terms that are no less favorable
     to the Company or the relevant Restricted Subsidiary than those that would
     have been obtained in a comparable transaction by the Company or such
     Restricted Subsidiary with a Person that is not an Affiliate; and

          (b) the Company delivers to the Trustee:


<PAGE>
                                      -71-


               (i) with respect to any Affiliate Transaction or series of
          related Affiliate Transactions involving aggregate consideration in
          excess of $5.0 million, a resolution of the Board of Directors set
          forth in an Officers' Certificate certifying that such Affiliate
          Transaction complies with Section 4.11 and that such Affiliate
          Transaction has been approved by a majority of the disinterested
          members of the Board of Directors and is in the best interests of the
          Company or such Restricted Subsidiary; and

               (ii) with respect to any Affiliate Transaction or series of
          related Affiliate Transactions involving aggregate consideration in
          excess of $10.0 million, an opinion as to the fairness to the Holders
          of such Affiliate Transaction from a financial point of view issued by
          an accounting, appraisal or investment banking firm of national
          standing.

     The following items shall not be deemed to be Affiliate Transactions and,
therefore, shall not be subject to the provisions of the prior paragraph:

               (a) reasonable fees and compensation paid to, and indemnity
          provided on behalf of, officers, directors, employees, agents or
          consultants of the Company or any of its Restricted Subsidiaries as
          determined in good faith by the Board of Directors or senior
          management of the Company;

               (b) transactions between or among the Company and any of the
          Company's Restricted Subsidiaries;

               (c) any sale or other issuance of Equity Interests (other than
          Disqualified Stock) of the Company;

               (d) Restricted Payments that are permitted by the provisions of
          Section 4.07 or by clauses (1), (3), (6), (7) or (8) of the definition
          of "Permitted Investments"; and

               (e) any agreement or arrangement as in effect on the Issue Date
          or any amendment thereto or any transaction contemplated thereby
          (including pursuant to any amendment thereto) in any replacement
          agreement or arrangement thereto so long as any such amendment or
          replacement agreement or arrangement is not more disadvantageous to
          the Company or its Restricted Subsidiaries, as the case may be, in any
          material respect than the original agreement as in effect on the Issue
          Date.

                                      -72-


Section 4.12. Liens.

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien of any kind on any asset now owned or hereafter acquired, except
Permitted Liens, without providing that the Notes shall be secured equally and
ratably with the Indebtedness so secured for so long as such obligations are so
secured.

Section 4.13. Business Activities.

     The Company shall not, and shall not permit any Restricted Subsidiary to,
engage to any material extent in any business other than the Telecommunications
Business.

Section 4.14. Corporate Existence.

     Subject to Article 5 hereof, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate
existence, and the corporate, partnership or other existence of each of its
Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of the Company or any such Subsidiary and
(ii) the rights (charter and statutory), licenses and franchises of the Company
and its Subsidiaries; provided, however, that the Company shall not be required
to preserve any such right, license or franchise, or the corporate, partnership
or other existence of any of its Subsidiaries, if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries, taken as a whole, and that the
loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15. Repurchase at the Option of Holders upon a Change of Control.

     Upon the occurrence of a Change of Control, each Holder of Notes shall have
the right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of that Holder's Notes pursuant to the Change
of Control Offer. In the Change of Control Offer, the Company shall offer (the
"Change of Control Offer") a payment ( the "Change of Control Payment") in cash
equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest, if any, thereon to the date of purchase.

     Within 30 days following any Change of Control, the Company shall mail a
notice to each Holder (with a copy to the Trustee) describing the transaction or
transactions that constitute the Change of Control and stating:


<PAGE>
                                      -73-


          (a) the purchase price and the purchase date, which shall not exceed
     30 business days from the date such notice is mailed (the "Change of
     Control Payment Date");

          (b) that any Note not tendered shall continue to accrue interest;

          (c) that, unless the Company defaults in the payment of the Change of
     Control Payment, all Notes accepted for payment pursuant to the Change of
     Control Offer shall cease to accrue interest after the Change of Control
     Payment Date;

          (d) that Holders electing to have any Notes purchased pursuant to a
     Change of Control Offer shall be required to surrender the Notes, with the
     form entitled, "Option of Holder to Elect Purchase" on the reverse of the
     Notes completed, to the Paying Agent at the address specified in the notice
     prior to the close of business on the third Business Day preceding the
     Change of Control Payment Date;

          (e) that Holders shall be entitled to withdraw their election if the
     Paying Agent receives, not later than the close of business on the second
     Business Day preceding the Change of Control Payment Date, a telegram,
     telex, facsimile transmission or letter setting forth the name of the
     Holder, the principal amount of Notes delivered for purchase, and a
     statement that such Holder is withdrawing his election to have the Notes
     purchased; and

          (f) that Holders whose Notes are being purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered, which unpurchased portion must be equal to $1,000 in
     principal amount or an integral multiple thereof. The Company shall comply
     with the requirements of Rule 14e-1 under the Exchange Act and any other
     securities laws and regulations thereunder to the extent such laws and
     regulations are applicable in connection with the repurchase of the Notes
     as a result of a Change of Control.

     On the Change of Control Payment Date, the Company shall, to the extent
lawful:

          (a) accept for payment all Notes or portions thereof properly tendered
     pursuant to the Change of Control Offer;

          (b) deposit with the Paying Agent an amount equal to the Change of
     Control Payment plus accrued and unpaid interest, if any, thereon in
     respect of all Notes or portions thereof so tendered; and


<PAGE>
                                      -74-


          (c) deliver or cause to be delivered to the Trustee the Notes so
     accepted together with an Officers' Certificate stating the aggregate
     principal amount of Notes or portions thereof being purchased by the
     Company.

     The Paying Agent shall promptly mail to each Holder of Notes so tendered
the Change of Control Payment plus accrued and unpaid interest, if any, thereon
for such Notes, and the Trustee shall promptly authenticate and mail (or cause
to be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided
that each such new Note shall be in a principal amount of $1,000 or an integral
multiple thereof. The Company shall publicly announce the results of the Change
of Control Offer on or as soon as practicable after the Change of Control
Payment Date.

     The provisions described above that require the Company to make a Change of
Control Offer following a Change of Control shall be applicable regardless of
whether or not any other provisions in this Indenture are applicable. Except as
described above with respect to a Change of Control, this Indenture does not
contain provisions that permit the Holders of the Notes to require that the
Company repurchase or redeem the Notes in the event of a takeover,
recapitalization or similar transaction.

     Notwithstanding any other provision of this Section 4.15, the Company shall
not be required to make a Change of Control Offer upon a Change of Control if a
third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in this Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.16. No Senior Subordinated Debt.

     Notwithstanding the provisions of Section 4.09 hereof, the Company shall
not incur any Indebtedness (including Permitted Debt) that is contractually
subordinated in right of payment to any other Indebtedness of the Company unless
such Indebtedness is also contractually subordinated in right of payment to the
Notes on substantially identical terms; provided, however, that no Indebtedness
of the Company shall be deemed to be contractually subordinated in right of
payment to any other Indebtedness of the Company solely by virtue of being
unsecured.

Section 4.17. Issuances of Guarantees by Restricted Subsidiaries.

     The Company shall not permit any Restricted Subsidiary, directly or
indirectly, to guarantee, assume or in any other manner become liable with
respect to any Indebtedness of the Company which is pari passu (other than any
Indebtedness incurred under a Credit Facility) with or subordinate in right of
payment to the Notes ("Guaranteed Indebtedness"), unless


<PAGE>
                                      -75-


(i) such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to this Indenture providing for a guarantee (a
"Subsidiary Guarantee") of payment of the Notes by such Restricted Subsidiary
and (ii) such Restricted Subsidiary waives and shall not in any manner
whatsoever claim, or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary as a result of any payment by such Restricted
Subsidiary under its Subsidiary Guarantee; provided that this paragraph shall
not be applicable to any guarantee of any Restricted Subsidiary that existed at
the time such Person became a Restricted Subsidiary and was not incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary. If the Guaranteed Indebtedness is (A) pari passu with the Notes,
then the guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated to the Notes, then
the guarantee of such Guaranteed Indebtedness shall be subordinated to the
Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness is
subordinated to the Notes.

     Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person that is not an Affiliate of the Company, of all of the Company's
and each Restricted Subsidiary's Capital Stock in, or all or substantially all
of the assets of, such Restricted Subsidiary (which sale, exchange or transfer
is not prohibited by this Indenture) or (ii) the release or discharge of the
guarantee which resulted in the creation of such Subsidiary Guarantee, except a
discharge or release by or as a result of payment under such guarantee.

Section 4.18. Designation of Restricted and Unrestricted Subsidiaries.

     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, all
outstanding Investments owned by the Company and its Restricted Subsidiaries in
the Subsidiary so designated shall be deemed to be an Investment made as of the
time of such designation and shall reduce the amount available for Restricted
Payments under the first paragraph of Section 4.07. All such outstanding
Investments shall be valued at their fair market value at the time of such
designation. That designation shall only be permitted if such Restricted Payment
would be permitted at that time and if such Restricted Subsidiary otherwise
meets the definition of an Unrestricted Subsidiary. The Board of Directors may
redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the
redesignation would not cause a Default and such redesignation shall increase
the amount available for Restricted Payments under the first paragraph of
Section 4.07 as provided therein or Permitted Investments, as applicable.

Section 4.19. Payments for Consent.

     The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder of Notes for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Notes
unless such consideration is offered to be paid and is paid to all Holders of
the Notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.

Section 5.01. Amalgamation, Merger, Consolidation, or Sale of Assets.

     The Company shall not, directly or indirectly: (1) amalgamate or
consolidate or merge with or into (whether or not the Company is the surviving
corporation); or (2) or sell, assign, transfer, convey or otherwise dispose of
all or substantially all of its properties or assets in one or more related
transactions to, another Person; unless:

          (a) either: (i) the Company is the surviving corporation; or (ii) the
     Person formed by or surviving any such amalgamation, consolidation or
     merger (if other than the Company) or to which such sale, assignment,
     transfer, conveyance or other disposition shall have been made is a
     corporation organized or existing under the laws of Canada or any province
     thereof or the United States, any state thereof or the District of
     Columbia;

          (b) the Person formed by or surviving any such amalgamation,
     consolidation or merger (if other than the Company) or the Person to which
     such sale, assignment, transfer, conveyance or other disposition shall have
     been made assumes all the obligations of the Company under the Notes, the
     Exchange Notes, this Indenture and the Registration Rights Agreement
     pursuant to agreements reasonably satisfactory to the Trustee;

          (c) no Default or Event of Default (or an event that, with the passing
     of time or giving of notice or both, would constitute an Event of Default)
     shall exist or shall occur immediately after giving effect on a pro forma
     basis to such transaction;

          (d) the transaction shall not result in the Company or the Person
     formed by or surviving any such amalgamation, consolidation or merger (if
     other than the Com-


<PAGE>

     pany) being required to make any deduction or withholding on account of
     Taxes as described under Section 3.07(c) and Section 4.05 from any payment
     under or in respect of the Notes that the Company would not have been
     required to make had such transaction or series of related transactions not
     occurred;

          (e) except in the case of the amalgamation, consolidation or merger of
     the Company with or into a Wholly-Owned Restricted Subsidiary, the Company
     or the Person formed by or surviving any such amalgamation, consolidation
     or merger (if other than the Company) shall, on the date of such
     transaction after giving pro forma effect thereto and any related financing
     transactions as if the same had occurred at the beginning of the applicable
     four-quarter period, be permitted to incur at least $1.00 of additional
     Indebtedness pursuant to clause (i) or (ii) of the first paragraph of
     Section 4.09; and

          (f) the Company shall have delivered to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that such amalgamation,
     consolidation, merger or transfer and such supplemental indenture, if any,
     comply with this Indenture.

     In addition, the Company may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. For purposes of the foregoing, the transfer
(by assignment, sale or otherwise) of all or substantially all of the properties
and assets of one or more Subsidiaries, the Company's interest in which
constitutes all or substantially all of the properties and assets of the
Company, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company. The provisions of this Section 5.01 shall
not apply to a sale, assignment, transfer, conveyance or other disposition of
assets between or among the Company and any of its Wholly-Owned Restricted
Subsidiaries.

Section 5.02. Successor Corporation Substituted.

     Upon any amalgamation, consolidation or merger or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of
the assets of the Company in accordance with Section 5.01, the successor
corporation formed by such amalgamation or consolidation or into which the
Company is merged or to which such transfer is made shall succeed to and (except
in the case of a lease) be substituted for, and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor corporation had been named therein as the Company, and (except in the
case of a lease) the Company shall be released from the obligations under the
Notes, and this Indenture except with respect to any obligations that arise
from, or are related to, such transaction.

                              DEFAULTS AND REMEDIES


Section 6.01. Events of Default.

     An "Event of Default" occurs if:

          (a) the Company defaults in the payment when due of interest on, or
     Additional Amounts, if any, with respect to, the Notes and such default
     continues for a period of 30 days;

          (b) the Company defaults in the payment when due of principal of or
     premium, if any, on the Notes;

          (c) the Company or any of its Restricted Subsidiaries fails to comply
     with any of the provisions of Article 5 hereof;

          (d) the Company or any of its Restricted Subsidiaries fails to observe
     or perform any of the provisions of Sections 4.10 and 4.15 for 15 days
     after notice to the Company by the Trustee or to the Company and the
     Trustee by the Holders of at least 25% in aggregate principal amount of the
     Notes (including Additional Senior Notes, if any) then outstanding;

          (e) the Company or any of its Restricted Subsidiaries fails to observe
     or perform any other covenant, representation, warranty or other agreement
     in this Indenture or the Notes for 60 days after notice to the Company by
     the Trustee or to the Company and the Trustee by the Holders of at least
     25% in aggregate principal amount of the Notes then outstanding;

          (f) the Company voluntarily relinquishes any of its rights under the
     Non-Competition Agreement or fails for 30 days after written notice thereof
     has been given to the Company by the Trustee or to the Company and the
     Trustee by the Holders of at least 25% in aggregate principal amount of the
     Notes then outstanding to enforce any of such rights, in each case which is
     materially detrimental to the interests of the Company or the Holders;

          (g) the Company defaults under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any Indebtedness for money borrowed (or the payment of which is
     guaranteed by the Com-


<PAGE>
                                      -79-


     pany or any of its Restricted Subsidiaries) whether such Indebtedness or
     guarantee now exists, or is created after the date of the Indenture, if
     that default:

               (i) is caused by a failure to pay principal of or premium, if
          any, on such Indebtedness prior to the expiration of the grace period
          provided in such Indebtedness on the date of such default (a "Payment
          Default"); or

               (ii) results in the acceleration of such Indebtedness prior to
          its express maturity, and, in each case, the principal amount of any
          such Indebtedness, together with the principal amount of any other
          such Indebtedness under which there has been a Payment Default or the
          maturity of which has been so accelerated, aggregates $10.0 million or
          more;

          (h) the Company or any of its Restricted Subsidiaries fails to pay
     final judgments which are non-appealable aggregating in excess of $10.0
     million (net of applicable insurance coverage which is acknowledged in
     writing by the insurer), which judgments are not paid, discharged or stayed
     for a period of 60 days;

          (i) the Company or any of its Restricted Subsidiaries pursuant to or
     within the meaning of Bankruptcy Law:

               (i) commences a voluntary case,

               (ii) consents to the entry of an order for relief against it in
          an involuntary case,

               (iii) consents to the appointment of a custodian of it or for all
          or substantially all of its property,

               (iv) makes a general assignment for the benefit of its creditors,
          or

               (v) generally is not paying its debts as they become due; and

          (j) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (i) is for relief against the Company or any of its Restricted
          Subsidiaries in an involuntary case;

               (ii) appoints a custodian of the Company or any of its Restricted
          Subsidiaries or for all or substantially all of the property of the
          Company or any of its Restricted Subsidiaries; or


<PAGE>
                                      -80-


               (iii) orders the liquidation of the Company or any of its
          Restricted Subsidiaries;

     and the order or decree remains unstayed and in effect for 60 consecutive
     days.

Section 6.02. Acceleration.

     If any Event of Default (other than an Event of Default specified in clause
(i) or (j) of Section 6.01 hereof with respect to the Company, any Restricted
Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary)
occurs and is continuing, the Trustee by notice to the Company or the Holders of
at least 25% in principal amount of the then outstanding Notes by notice to the
Company and the Trustee may declare all the Notes to be due and payable
immediately.

     Notwithstanding the foregoing, if an Event of Default specified in clause
(i) or (j) of Section 6.01 hereof occurs with respect to the Company, any
Restricted Subsidiary that is a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes shall be due and payable immediately without
further action or notice. The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may on
behalf of all of the Holders rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal, interest or premium that has
become due solely because of the acceleration) have been cured or waived.

Section 6.03. Other Remedies.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium, if any, and
interest on the Notes or to enforce the performance of any provision of the
Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing


<PAGE>
                                      -81-


Default or Event of Default in the payment of the principal of, premium, if any,
or interest on, the Notes (including in connection with an offer to purchase)
(provided, however, that the Holders of a majority in aggregate principal amount
of the then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

Section 6.05. Control by Majority.

     Holders of a majority in principal amount of the then outstanding Notes may
direct the time, method and place of conducting any proceeding for exercising
any remedy available to the Trustee or exercising any trust or power conferred
on it. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture that the Trustee determines may be unduly prejudicial
to the rights of other Holders of Notes or that may involve the Trustee in
personal liability. The Trustee may take any other action which it deems proper
that is not inconsistent with any such directive.

Section 6.06. Limitation on Suits.

     A Holder of a Note may pursue a remedy with respect to this Indenture or
the Notes only if:

          (a) the Holder of a Note gives to the Trustee written notice of a
     continuing Event of Default;

          (b) the Holders of at least 25% in principal amount of the then
     outstanding Notes make a written request to the Trustee to pursue the
     remedy;

          (c) such Holder of a Note or Holders of Notes offer and, if requested,
     provide to the Trustee indemnity satisfactory to the Trustee against any
     loss, liability or expense;

          (d) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer and, if requested, the provision of
     indemnity; and

          (e) during such 60day period the Holders of a majority in principal
     amount of the then outstanding Notes do not give the Trustee a direction
     inconsistent with the request.


<PAGE>
                                      -82-


     A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07. Rights of Holders of Notes to Receive Payment.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium, if any, and interest
on the Note, on or after the respective due dates expressed in the Note
(including in connection with an offer to purchase), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

Section 6.08. Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

     The Trustee is authorized to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan


<PAGE>
                                      -83-


of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

Section 6.10. Priorities.

     If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

          First: to the Trustee, its agents and attorneys for amounts due under
     Section 7.07 hereof, including payment of all compensation, expense and
     liabilities incurred, and all advances made, by the Trustee and the costs
     and expenses of collection;

          Second: to Holders of Notes for amounts due and unpaid on the Notes
     for principal, premium, if any, and interest, ratably, without preference
     or priority of any kind, according to the amounts due and payable on the
     Notes for principal, premium, if any and interest, respectively; and

          Third: to the Company or to such party as a court of competent
     jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to
Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount
of the then outstanding Notes.

Section 6.12. Indemnification for Judgment Currency Fluctuations.

     The obligations of the Company to any Holder of Notes shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
U.S. dollars (the "Agreement Currency"), be discharged only to the extent that
on the day following receipt by such Holder of Notes or the Trustee, as the case
may be, of any amount in the Judgment Currency, such Holder of Notes may in
accordance with normal banking procedures purchase the Agreement


<PAGE>
                                      -84-


Currency with the Judgment Currency. If the amount of the Agreement Currency so
purchased is less than the amount originally to be paid to such Holder of Notes
or the Trustee, as the case may be, in the Agreement Currency, the Company shall
pay the difference and if the amount of the Agreement Currency so purchased
exceeds the amount originally to be paid to such Holder of Notes or the Trustee,
as the case may be, such Holder of Notes or the Trustee, as the case may be,
shall pay to or for the account of the Company such excess, provided that such
Holder of Notes or the Trustee, as the case may be, shall not have any
obligation to pay any such excess as long as a Default by the Company in its
obligations under the Notes or this Indenture has occurred and is continuing, in
which case such excess may be applied by such Holder of Notes to such
obligations.


                                    ARTICLE 7

                                     TRUSTEE


Section 7.01. Duties of Trustee.

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

     (b) Except during the continuance of an Event of Default:

          (i) the duties of the Trustee shall be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, and no implied covenants or obligations shall be read into this
     Indenture against the Trustee; and

          (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

action, its own negligent failure to act, or its own willful misconduct, except
that:

     good faith by a Responsible Officer, unless it is proved that the Trustee

expense.

an Officer of the Company.

the Holders unless such Holders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that might be

     (g) The Trustee shall not be charged with knowledge of any Default or Event
of Default with respect to the Notes unless either (1) a Responsible Officer of

pledgee of Notes and may otherwise deal with the Company or any Affiliate of the
Company with the same rights it would have if it were not Trustee. However, in
the event that the Trustee acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the SEC for permission to continue as
trustee or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04. Trustee's Disclaimer.

<PAGE>
                                      -87-


of principal of, premium, if any, or interest on any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of the
Holders of the Notes.

Section 7.06. Reports by Trustee to Holders of the Notes.

     Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, and for so long as Notes remain outstanding, the Trustee
shall mail to the Holders of the Notes a brief report dated as of such reporting
date that complies with TIA ss. 313(a) (but if no event described in TIA ss.
313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 313(c).

     A copy of each report at the time of its mailing to the Holders of Notes
shall be mailed to the Company and filed with the SEC and each stock exchange on
which the Notes are listed in accordance with TIA ss. 313(d). The Company shall
promptly notify the Trustee when the Notes are listed on any stock exchange.

Section 7.07. Compensation and Indemnity.

     The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

     The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so notify the
Company shall not relieve the Company of its obligations hereunder. The Company
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

                                      -88-


     The obligations of the Company under this Section 7.07 shall survive
resignation or removal of the Trustee and the satisfaction and discharge of this
Indenture.

     To secure the Company's payment obligations in this Section, the Trustee
shall have a Lien prior to the Notes on all money or property held or collected
by the Trustee, except that held in trust to pay principal and interest on
particular Notes. Such Lien shall survive the resignation or removal of the
Trustee and the satisfaction and discharge of this Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(i) or (j) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

     The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to the
extent applicable.

Section 7.08. Replacement of Trustee.

     A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

     The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Company. The Holders of a majority in
principal amount of the then outstanding Notes may remove the Trustee by so
notifying the Trustee and the Company in writing. The Company may remove the
Trustee if:

          (a) the Trustee fails to comply with Section 7.10 hereof;

          (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

          (c) a custodian or public officer takes charge of the Trustee or its
     property; or

          (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.


<PAGE>
                                      -89-


     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in principal amount of the then outstanding Notes
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     If the Trustee, after written request by any Holder who has been a Holder
for at least six months, fails to comply with Section 7.10, such Holder may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, etc.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act shall be the successor Trustee.

Section 7.10. Eligibility; Disqualification.

     There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100 million
as set forth in its most recent published annual report of condition.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIAss. 310(b).

Section 7.11. Preferential Collection of Claims Against Company.

     The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE


Section 8.01. Option To Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at the option of the Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article Eight.

Section 8.02. Legal Defeasance and Discharge.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder:

          (a) the rights of Holders of outstanding Notes to receive payments in
     respect of the principal of, premium, if any, and interest on such Notes
     when such payments are due from the trust referred to below;

          (b) the Company's obligations with respect to the Notes concerning
     issuing temporary Notes, registration of Notes, mutilated, destroyed, lost
     or stolen Notes and the maintenance of an office or agency for payment and
     money for security payments held in trust;

          (c) the rights, powers, trusts, duties and immunities of the Trustee,
     and the Company's obligations in connection therewith;

          (d) the Legal Defeasance provisions of this Indenture; and

          (e) the Company's obligation to pay Additional Amounts.


<PAGE>
                                      -91-


     Subject to compliance with this Article Eight, the Company may exercise its
option under this Section 8.02 notwithstanding the prior exercise of its option
under Section 8.03 hereof.

Section 8.03. Covenant Defeasance.

     Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Article 5 and Sections 4.03, 4.07,
4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16 and 4.17 hereof with respect to
the outstanding Notes on and after the date the conditions set forth in Section
8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Company's exercise under Section
8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(c) through 6.01(e) hereof and Section 6.01(g) hereof shall not constitute
Events of Default.

Section 8.04. Conditions to Legal or Covenant Defeasance.

     The following shall be the conditions to the application of either Section
8.02 or 8.03 hereof to the outstanding Notes:

     In order to exercise either Legal Defeasance or Covenant Defeasance:

     for the benefit of the Holders of the Notes, cash in U.S. dollars,
     non-callable Government Securities, or a combination thereof, in such

     firm of independent public accountants, to pay the principal of, premium,
     if any, and interest on the outstanding Notes on the stated maturity or on
     the applicable redemption date, as the case may be, and the Company must
     specify whether the Notes are being defeased to maturity or to a particular
     redemption date;

     from, or there has been published by, the Internal Revenue Service a ruling
     or (b) since the Issue Date, there has been a change in the applicable
     federal income tax law, in either case to the effect that, and based
     thereon such opinion of counsel shall confirm that, the Holders of the
     outstanding Notes shall not recognize income, gain or loss for United
     States federal income tax purposes as a result of such Legal Defeasance and
     shall be subject to United States federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if

     Trustee confirming that the Holders of the outstanding Notes shall not
     recognize income, gain or loss for Canadian federal income tax purposes as
     a result of such Legal Defeasance and shall be subject to Canadian federal
     income tax on the same amounts, in the same manner and at the same times as
     would have been the case if such Legal Defeasance had not occurred;

          (c) in the case of an election under Section 8.03 hereof, the Company
     shall have delivered to the Trustee an Opinion of Counsel reasonably

     income tax purposes as a result of such Covenant Defeasance and shall be
     subject to United States federal income tax on the same amounts, in the
     same manner and at the same times as would have been the case if such
     Covenant Defeasance had not occurred and the Company shall have delivered
     to the Trustee an opinion of counsel in Canada reasonably acceptable to the
     Trustee confirming that the Holders of the outstanding Notes shall not
     recognize income, gain or loss for Canadian federal income tax purposes as
     a result of such Covenant Defeasance and shall be subject to Canadian
     federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if such Covenant Defeasance had not
     occurred;

          (d) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the incurrence of Indebtedness all or a portion of
     the proceeds of which shall be used to defease the Notes pursuant to this
     Article Eight concurrently with such incurrence) or insofar as Sections
     6.01(i) or 6.01(j) hereof is concerned, at any time in the period ending on
     the 91st day after the date of deposit;

          (e) such Legal Defeasance or Covenant Defeasance shall not result in a
     breach or violation of, or constitute a default under, any material
     agreement or instrument (other than this Indenture) to which the Company or
     any of its Restricted Sub-

     Counsel (which may be subject to customary exceptions) to the effect that
     on the 91st day following the deposit, the trust funds shall not be subject
     to the effect of any applicable bankruptcy, insolvency, reorganization or
     similar laws affecting creditors' rights generally;

          (g) the Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders over any other creditors of the Company or
     with the intent of defeating, hindering, delaying or defrauding creditors
     of the Company or others; and

     (b), (c) and (e) have been complied with.

Section 8.05. Deposited Money and Government Securities to be Held in Trust;
              Other Miscellaneous Provisions.

     Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

     Anything in this Article Eight to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable


<PAGE>
                                      -94-


Government Securities held by it as provided in Section 8.04 hereof which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may
be the opinion delivered under Section 8.04(a) hereof), are in excess of the
amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06. Repayment to Company.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or

and premium, if any, or interest has become due and payable shall be paid to the
Company on its request or (if then held by the Company) shall be discharged from
such trust; and the Holder of such Note shall thereafter look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in the New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining shall be repaid to the Company.

Section 8.07. Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars
or non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

Section 9.02. With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including Section 3.09, 4.10 and 4.15
hereof) and the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the Notes (including
Additional Senior Notes, if any) then outstanding voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any


<PAGE>
                                      -96-


existing Default or Event of Default (other than a Default or Event of Default
in the payment of the principal of, premium, if any, or interest on the Notes,
except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture or the Notes may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including Additional Senior Notes, if any) voting as a single
class (including consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which
Notes are considered to be "outstanding" for purposes of this Section 9.02.

     Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Company in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.

     It shall not be necessary for the consent of the Holders of Notes under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

     After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes (including Additional Senior
Notes, if any) then outstanding may waive compliance in a particular instance by
the Company with any provision of this Indenture or the Notes. However, without
the consent of each Holder affected, an amendment or waiver under this Section
9.02 may not (with respect to any Notes held by a non-consenting Holder):

          (a) reduce the principal amount of Notes whose Holders must consent to
     an amendment, supplement or waiver;

          (b) reduce the principal of or change the fixed maturity of any Note
     or alter or waive any of the provisions with respect to the redemption of
     the Notes (except as provided above with respect to Sections 4.10 and 4.15
     hereof);


<PAGE>
                                      -97-


          (c) reduce the rate of or change the time for payment of interest on
     any Note;

          (d) waive a Default or Event of Default in the payment of principal of
     or premium, if any, or interest on the Notes (except a rescission of
     acceleration of the Notes by the Holders of at least a majority in
     aggregate principal amount of the then outstanding Notes (including
     Additional Senior Notes, if any) and a waiver of the payment default that
     resulted from such acceleration);

          (e) make any Note payable in money other than that stated in the
     Notes;

          (f) make any change in the provisions of this Indenture relating to
     waivers of past Defaults or the rights of Holders of Notes to receive
     payments of principal of or premium, if any, or interest on the Notes;

          (g) waive a redemption payment with respect to any Note (other than a
     payment required by one of the covenants described in Sections 4.10 and
     4.15)

          (h) cause the Notes to become subordinate in right of payment to any
     other Indebtedness;

          (i) make any change that would adversely affect the rights of the
     Holders to receive Additional Amounts;

          (j) modify the obligation of the Company to make a Change of Control
     Offer to purchase Notes after the occurrence of an event which constitutes
     a Change of Control; or

          (k) make any change in the preceding amendment and waiver provisions.

Section 9.03. Compliance with Trust Indenture Act.

     Every amendment or supplement to this Indenture or the Notes shall be set
forth in a amended or supplemental Indenture that complies with the TIA as then
in effect.

Section 9.04. Revocation and Effect of Consents.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Note is a continuing consent by the Holder of a Note and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of
revocation before the date the waiver, supplement or amendment becomes

<PAGE>
                                      -98-


effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

Section 9.05. Notation on or Exchange of Notes.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

     Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06. Trustee to Sign Amendments, etc.

     The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article Nine if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental Indenture until the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section
10.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that
the execution of such amended or supplemental indenture is authorized or
permitted by this Indenture.

                             SATISFACTION AND WAIVER


Section 9.01A Satisfaction and Discharge of Indenture.

     This Indenture shall be discharged and shall cease to be of further effect
as to all Notes issued hereunder, when either (a) all such Notes theretofore
authenticated and delivered (except lost, stolen or destroyed Notes which have
been replaced or paid and Notes for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Company) have been delivered to
the Trustee for cancellation; or (b)(i) all such Notes not theretofore delivered
to the Trustee for cancellation have become due and payable by reason of the
making of a notice of redemption or otherwise or will become due and payable
within one year and the Company has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust an amount of money sufficient
to pay and discharge the entire Indebtedness on such Notes not theretofore
delivered to the Trustee for cancellation for principal, premium, if


<PAGE>
                                      -99-


any, and accrued interest to the date of maturity or redemption; (ii) no Default
or Event of Default with respect to this Indenture or the Notes shall have
occurred and be continuing on the date of such deposit or shall occur as a
result of such deposit and such deposit shall not result in a breach or
violation of, or constitute a default under, any other instrument to which the
Company is a party or by which the Company or a Subsidiary Guarantor, if any, is
bound: (iii) the Company has paid or caused to be paid all sums payable by it
under this Indenture; and (iv) the Company has delivered irrevocable
instructions to the Trustee under this Indenture to apply the deposited money
toward the payment of such Notes at maturity or the redemption date, as the case
may be.

     In addition, the Company shall deliver an Officer's Certificate and an
Opinion of Counsel to the Trustee stating that all conditions precedent to the
satisfaction and discharge of this Indenture have been satisfied.

Section 9.02A Application of Trust Money.

     All money deposited with the Trustee pursuant to Section 9.01A shall be
held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine, to
Persons entitled thereto, of the principal (and premium, if any) and interest
for whose payment such money has been deposited with the Trustee.

     If the Trustee or Paying Agent is unable to apply any money in accordance
with Section 9.01A by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though such deposit
had not occurred pursuant to Section 9.01A; provided that if the Company has
made any payment of principal of, premium, if any, or interest on any Notes
because of the reinstatement of its obligations, the money shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the
Company or money held by the Trustee or Paying Agent.

connection with any such suit or proceeding), and irrevocably agrees that all

such service. The Company further agrees that service of process upon the
Process Agent and written notice of said service to the Company mailed by
prepaid registered first class mail or delivered to the Process Agent at its
principal office, shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect the
right of any Holder or any Person controlling such Holder to serve process in
any other manner permitted by law. The Company further agrees to take any and
all action, including the execution and filing of any and all such documents and
instruments as may be necessary to continue such designation and appointment of
the Process Agent in full force and effect so long as the Company has any
outstanding obligations under this Agreement. To the extent that the Company has
or hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service of note, attachment prior to judgment,
attachment in aid of execution, executor or otherwise) with respect to itself or
its property, the Company hereby irrevocably waives such immunity in respect of
their obligations under this Indenture, to the extent permitted by law.

     Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

     1. INTEREST. Worldwide Fiber Inc., a company incorporated under the laws of
Alberta (the "Company"), promises to pay interest on the principal amount of
this Note at the rate of 12% per annum from July 28, 1999 until maturity. The
interest rate on the Notes is subject to increase pursuant to the provisions of
the Registration Rights Agreement. The Company will pay interest semi-annually
in arrears on August 1 and February 1 of each year (each an "Interest Payment
Date"), or if any such day is not a Business Day, on the next succeeding
Business Day. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to on
the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be February 1, 2000. The Company shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360day year of twelve
30-day months.

     2. METHOD OF PAYMENT. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the
close of business on the July 15 or January 15 next preceding the Interest
Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be payable as to
principal, premium, if any, and interest at the office or agency of the Company
maintained for such purpose within or without the City and State of New York,
or, at the option of the Company, payment of interest may be made by check
mailed to the Holders at their addresses set forth in the register of Holders,
and provided that payment by wire transfer of immediately available funds will
be required with respect to principal of and interest, premium on, all Global
Notes and all other Notes the Holders of which shall have provided wire transfer
instructions to the Company or the Paying Agent. Such payment shall be in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.

     3. PAYING AGENT AND REGISTRAR. Initially, HSBC Bank USA, the Trustee under
the Indenture, will act as Paying Agent and Registrar. The Company may change
any

                                      A-5
<PAGE>


Paying Agent or Registrar without notice to any Holder. The Company or any of
its Subsidiaries may act in any such capacity.

     4. INDENTURE. The Company issued the Notes under an Indenture dated as of
July 28, 1999 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code ss.ss. 77aaa-77bbbb). The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Initial Notes are obligations of the Company limited to $500.0 million in
aggregate principal amount.

     5. OPTIONAL REDEMPTION.

     (a) Except as set forth in subparagraph (b) and (c) of this Paragraph 5,
the Company shall not have the option to redeem the Notes prior to August 1,
2004. Thereafter, the Company shall have the option to redeem the Notes, in
whole or in part, upon not less than 30 nor more than 60 days' notice, at the
redemption prices (expressed as percentages of principal amount) set forth below
plus accrued and unpaid interest, if any, thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on August 1 of the
years indicated below:

        Date                                             Percentage
        ----                                             ----------
        2004..........................................   106.000%
        2005..........................................   104.000%
        2006..........................................   102.000%
        2007 and thereafter...........................   100.000%

     (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5,
prior to August 1, 2002, the Company may on any one or more occasions redeem up
to 35% of the sum of (a) the aggregate principal amount of Notes originally
issued under the Indenture and (b) the total amount of Additional Senior Notes
issued under the Indenture at a redemption price of 112% of the principal amount
thereof, plus accrued and unpaid interest, if any, thereon to the redemption
date, with the net cash proceeds of one or more Public Equity Offerings;
provided that

          (i) at least 65% of the sum of (a) the aggregate principal amount of
     Notes originally issued under the Indenture and (b) the total amount of
     Additional Senior Notes issued under the Indenture remains outstanding
     immediately after the oc-


                                      A-6
<PAGE>


     currence of any such redemption (excluding Notes held by the Company and
     its Subsidiaries); and

          (ii) the redemption must occur within 90 days of the date of the
     closing of such Qualified Equity Offering.

     (c) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5,
the Company may redeem the Notes in the event the Company becomes obligated to
pay any Additional Amounts as a result of a change in the laws or regulations of
Canada or any Canadian Taxing Authority, or a change in any official position
regarding the application or interpretation thereof, which is publicly announced
or becomes effective on or after the Issue Date. Upon the occurrence of any such
change, the Company may, at any time, redeem all, but not part, of the Notes at
a price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date. The Company will give written notice
of any such redemption not less than 30 nor more than 60 days prior to the
redemption date.

     6. PAYMENT OF ADDITIONAL AMOUNTS. All payments made by or on behalf of the
Company on or with respect to the Notes shall be made without withholding or
deduction for any Taxes imposed by any Canadian Taxing Authority, unless
required by law or the interpretation or administration thereof by the relevant
Taxing Authority. If the Company or any other payor is required to withhold or
deduct any amount on account of Taxes from any payment made on or with respect
to the Notes, the Company shall:

          (a) make such withholding or deduction;

          (b) remit the full amount deducted or withheld to the relevant
     government authority in accordance with applicable law;

          (c) pay such additional amounts ("Additional Amounts") as may be
     necessary so that the net amount received by each Holder (including
     Additional Amounts) after such withholding or deduction shall not be less
     than the amount the Holder would have received if such Taxes had not been
     withheld or deducted;

          (d) furnish to the Holders, within 30 days after the date the payment
     of any Taxes is due, certified copies of tax receipts evidencing such
     payment by the Company;

          (e) indemnify and hold harmless each Holder (other than an Excluded
     Holder) for the amount of (i) any Taxes paid by such Holder as a result of
     payments made on or with respect to the Notes, (ii) any liability
     (including penalties, interest and expenses) arising therefrom or with
     respect thereto and (iii) any Taxes imposed with


                                      A-7
<PAGE>


     respect to any reimbursement under (i) or (ii), but excluding any such
     Taxes on such Holder's net income; and

          (f) at least 30 days prior to each date on which any Additional
     Amounts are payable, deliver to the Trustee an Officers' Certificate
     stating the amounts so payable and such other information necessary to
     enable the Trustee to pay such Additional Amounts to Holders on the payment
     date.

     Notwithstanding the foregoing, no Additional Amounts shall be payable to a
Holder in respect of a beneficial owner of a Note (an "Excluded Holder"):

          (a) with which the Company does not deal at arm's length (within the
     meaning of the Income Tax Act (Canada)) at the time of making such payment;
     or

          (b) which is subject to such Taxes by reason of its being connected
     with Canada or any province or territory thereof otherwise than by the mere
     acquisition, holding or disposition of Notes or the receipt of payments
     thereunder.

     7. MANDATORY REDEMPTION. Except as otherwise provided in Paragraph 8 below,
the Company shall not be required to make mandatory redemption payments with
respect to the Notes. In addition, the Company is not required to make any
sinking fund payments with respect to the Notes.

     8. REPURCHASE AT OPTION OF HOLDER.

     (a) Upon the occurrence of a Change of Control, each Holder of Notes shall
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of that Holder's Notes pursuant to the
Change of Control Offer. In the Change of Control Offer, the Company will offer
(the "Change of Control Offer") a Change of Control Payment in cash equal to
101% of the aggregate principal amount of Notes repurchased plus accrued and
unpaid interest, if any, thereon to the date of purchase. Within 30 days
following any Change of Control, the Company will mail a notice to each Holder
(with a copy to the Trustee) describing the transaction or transactions that
constitute the Change of Control and offering to repurchase Notes on the Change
of Control Payment Date specified in such notice, pursuant to the procedures
required by the Indenture and described in such notice. The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Notes as a
result of a Change of Control.


                                      A-8
<PAGE>


     (b) If the Company or a Subsidiary consummates any Asset Sale, within five
days of each date on which the aggregate amount of Excess Proceeds exceeds $10
million, the Company shall commence an offer to all Holders of Notes (an "Asset
Sale Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum
principal amount of Notes (including Additional Senior Notes, if any) that may
be purchased out of the Excess Proceeds at an offer price in cash in an amount
equal to 100% of the principal amount thereof plus accrued and unpaid interest
thereon, if any, to the date fixed for the closing of such offer, in accordance
with the procedures set forth in the Indenture. To the extent that the aggregate
amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds, the Company (or such Subsidiary) may use such deficiency for any
purpose not otherwise prohibited by the Indenture. If the aggregate principal
amount of Notes surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes to be purchased on a pro rata
basis. Holders of Notes that are the subject of an offer to purchase will
receive an Asset Sale Offer from the Company prior to any related purchase date
and may elect to have such Notes purchased by completing the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Notes.

     9. NOTICE OF REDEMPTION. Notice of redemption will be mailed by first class
mail at least 30 days but not more than 60 days before the redemption date to
each Holder whose Notes are to be redeemed at its registered address. Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes or
portions thereof called for redemption.

     10. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

     11. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated
as its owner for all purposes, other than with respect to the payment of
Additional Amounts.


                                      A-9

     12. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
(including Additional Senior Notes, if any), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including Additional Senior Notes, if any). Without the
consent of any Holder of a Note, the Indenture or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation or sale of all or substantially all of the
Company's assets, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, to comply with the requirements
of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA or to provide for the Issuance of Additional Senior Notes in
accordance with the limitations set forth in the Indenture.

     13. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on, or Additional Amounts, if any, with
respect to the Notes, (ii) default in payment when due of principal of or
premium, if any, on the Notes, (iii) failure by the Company or any of its
Restricted Subsidiaries to comply with Section 5.01 of the Indenture, (iv)
failure by the Company or any of its Restricted Subsidiaries for 15 days after
notice to the Company by the Trustee or to the Company and the Trustee by the
Holders of at least 25% in principal amount of the Notes (including Additional
Senior Notes, if any) then outstanding to comply with Section 4.10 or 4.15 of
the Indenture or the Notes, (v) failure by the Company or any of its Restricted
Subsidiaries for 60 days after notice to the Company by the Trustee or to the
Company and the Trustee by the Holders of at least 25% in principal amount of
the Notes then outstanding to comply with any of the other agreements in the
Indenture or the Notes, (vi) voluntary relinquishment by the Company of any of
its rights under the Non-Competition Agreement or failure by the Company for 30
days after written notice thereof has been given to the Company by the Trustee
or to the Company and the Trustee by Holders of at least 25% of the aggregate
principal amount of the Notes outstanding to enforce any of such rights, in each
case which is materially detrimental to the interests of the Company or the
Holders, (vii) default under certain other agreements relating to Indebtedness
of the Company which default results in the acceleration of such Indebtedness
prior to its express maturity; (viii) certain final judgments for the payment of
money that remain undischarged for a period of 60 days; (ix) certain events of
bankruptcy or insolvency with respect to the Company or any of its Material
Subsidiaries. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable. Notwithstanding the foregoing,
in the case of an


                                     A-10
<PAGE>


Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Notes will become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of interest on,
or the principal of, the Notes. The Company is required to deliver to the
Trustee annually a statement regarding compliance with the Indenture, and the
Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

     14. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

     15. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator
or stockholder, of the Company, as such, shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the Notes.

     16. GOVERNING LAW. This Note and the Indenture shall be governed by and
construed in accordance with the laws of the State of New York, as applied to
contracts made and performed within the State of New York, without regard to
principles of conflict of laws. Each of the parties hereto and the holders agree
to submit to the jurisdiction of the courts of the State of New York in any
action or proceeding arising out of or relating to this Note.

     17. AUTHENTICATION. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

     18. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

     19. ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND RESTRICTED
DEFINITIVE NOTES. In addition to the rights provided to Holders of Notes under

Lufkin & Jenrette Securities Corporation, Morgan Stanley & Co. Incorporated,
Salomon Smith Barney Inc. and TD Securities (USA) Inc. (the "Registration Rights
Agreement").

     20. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

SECTION 2. HOLDERS

     A Person is deemed to be a holder of Transfer Restricted Securities (each,
a "Holder") whenever such Person owns Transfer Restricted Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

     (a) Unless the Exchange Offer shall not be permitted by applicable federal
law (after the procedures set forth in Section 6(a)(i) below have been complied
with), the Company shall (i) cause the Exchange Offer Registration Statement to
be filed with the Commission as soon as practicable after the Closing Date, but
in no event later than 90 days after the Closing Date (such 90th day being the
"Filing Deadline"), (ii) use its reasonable best efforts to cause such Exchange
Offer Registration Statement to become effective at the earliest possible time,
but in no event later than 180 days after the Closing Date (such 180th day being
the "Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file
all pre-effective amendments to such Exchange Offer Registration Statement as
may be necessary in order to cause it to become effective, (B) file, if
applicable, a post-effective amendment to such Exchange Offer Registration
Statement pursuant to Rule 430A under the Act and (C) cause all necessary
filings, if any, in connection with the registration and qualification of the
Series B Notes to be made under the Blue Sky laws of such jurisdictions as are
necessary to permit Consummation of the Exchange Offer, and (iv) upon the
effectiveness of such Exchange Offer Registration Statement, commence and
Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate
form permitting (i) registration of the Series B Notes to be offered in exchange
for the Series A Notes that are Transfer Restricted Securities and (ii) resales
of Series B Notes by Broker-Dealers that tendered into the Exchange Offer Series
A Notes that such Broker-Dealer acquired for its own account as a result of
market making activities or other trading activities (other than Series A Notes
acquired directly from the Company or any of its Affiliates) as contemplated by
Section 3(c) below.

     (b) The Company shall use its reasonable best efforts to cause the Exchange
Offer Registration Statement to be effective continuously, and shall keep the
Exchange Offer open for a period of not less than the minimum period required
under applicable federal and state securities laws to Consummate the Exchange
Offer; provided, however, that in no event shall such period be less than 20
Business Days. The Company shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the
Series B Notes shall be included in the Exchange Offer Registration Statement.
The Company shall use its reasonable best efforts to cause the Exchange Offer to
be Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 210 days
after the Closing Date (such 210th day being the "Consummation Deadline").



                                       5
<PAGE>

     (c) The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement.

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company shall
permit the use of the Prospectus contained in the Exchange Offer Registration
Statement by such Broker-Dealer to satisfy such prospectus delivery requirement.
To the extent necessary to ensure that the prospectus contained in the Exchange
Offer Registration Statement is available for sales of Series B Notes by
Broker-Dealers, the Company agrees to use its reasonable best efforts to keep
the Exchange Offer Registration Statement continuously effective, supplemented,
amended and current as required by and subject to the provisions of Sections
6(a) and (c) hereof and in conformity with the requirements of this Agreement,
the Act and the policies, rules and regulations of the Commission as announced
from time to time, for a period of one year (excluding any Exchange Offer
Blackout Period (as defined)) from the Consummation Deadline or such shorter
period as will terminate when all Transfer Restricted Securities covered by such
Registration Statement have been sold pursuant thereto; provided, further, that
the Company may suspend the effectiveness of the Exchange Offer Registration
Statement, in the event that, and for up to 2 periods of up to 30 consecutive
days, but no more than an aggregate of 45 days (an "Exchange Offer Blackout
Period") if, (a)(i) an event occurs and is continuing as a result of which the
Exchange Offer Registration Statement would, in the Company's good faith
judgment, contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein not misleading
and (ii) if the Company determines in good faith that the disclosure of such
event at such time would have a material adverse effect on the business
operations or prospectus of the Company or (b) the disclosure otherwise relates
to a pending material business transaction which has not yet been publicly
disclosed; provided, further, that the Company shall continue to pay Additional
Interest, if any, during the Exchange Offer Blackout Period. Upon the occurrence
of any such suspension, the Company will use its best efforts to reinstate
effectiveness of such Exchange Offer Registration Statement as soon as
practicable. The Company shall provide sufficient copies of the latest



                                       6
<PAGE>

version of such Prospectus to such Broker-Dealers, promptly upon request, and in
no event later than one day after such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

     (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law or Commission Policy (after the Company has complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the consummation of the Exchange Offer that (A) such Holder was prohibited by
law or Commission policy from participating in the Exchange Offer or (B) such
Holder may not resell the Series B Notes acquired by it in the Exchange Offer to
the public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds Series A
Notes acquired directly from the Company or any of its Affiliates, then the
Company shall:

          (x) cause to be filed, on or prior to 30 days after the earlier of (i)
     the date on which the Company determines that the Exchange Offer
     Registration Statement cannot be filed as a result of clause (a)(i) above
     and (ii) the date on which the Company receives the notice specified in
     clause (a)(ii) above, (but no earlier than 90 days after the Closing Date)
     (such earlier date, which shall not be earlier than 90 days after the
     Closing Date, the "Filing Deadline"), a shelf registration statement
     pursuant to Rule 415 under the Act (which may be an amendment to the
     Exchange Offer Registration Statement (the "Shelf Registration
     Statement")), relating to all Transfer Restricted Securities, and

          (y) shall use its reasonable best efforts to cause such Shelf
     Registration Statement to become effective on or prior to 90 days after the
     Filing Deadline for the Shelf Registration Statement (but no earlier than
     210 days after the Closing Date) (such day being the "Effectiveness
     Deadline").

     If, after the Company has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Company is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e., clause
(a)(i) above), then the filing of the Exchange Offer Registration Statement
shall be deemed to satisfy the requirements of clause (x) above; provided that,
in such event, the Company shall remain obligated to meet the Effectiveness
Deadline set forth in clause (y).

     To the extent necessary to ensure that the Shelf Registration Statement is
available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section




                                       7
<PAGE>

6(b)(ii) hereof, the Company shall use its reasonable best efforts to keep any
Shelf Registration Statement required by this Section 4(a) continuously
effective, supplemented, amended and current as required by and subject to the
provisions of Sections 6(b) and (c) hereof and in conformity with the
requirements of this Agreement, the Act and the policies, rules and regulations
of the Commission as announced from time to time, for as long as any Initial
Purchaser is deemed to be an Affiliate of the Company, but in no event less than
the shorter of (i) two years (excluding any Shelf Blackout period (as defined))
(as extended pursuant to Section 6(d)) following the Closing Date or (ii) the
date on which all Transfer Restricted Securities covered by such Shelf
Registration Statement have been sold pursuant thereto; provided, further, that
the Company may suspend the effectiveness of a Shelf Registration Statement, in
the event that, and for up to three periods of up to 45 consecutive days, but no
more than an aggregate of 90 days during any 365-day period (a "Shelf Blackout
Period") if, (a)(i) an event occurs and is continuing as a result of which the
Shelf Registration Statement would, in the Company's good faith judgment,
contain an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein not misleading and (ii) if the
Company determines in good faith that the disclosure of such event at such time
would have a material adverse effect on the business, operations or prospects of
the Company or (b) the disclosure otherwise relates to a pending material
business transaction which has not yet been publicly disclosed; provided,
however, that the Company shall not pay Additional Interest, during any such
Shelf Blackout Period. Upon the occurrence of any such suspension, the Company
will use its reasonable best efforts to reinstate effectiveness of such Shelf
Registration Statement as soon as practicable.

     (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to additional interest pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

SECTION 5. ADDITIONAL INTEREST

     If (i) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (ii) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not
been Consummated on or prior to the



                                       8
<PAGE>

Consummation Deadline or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose without being succeeded
within two days by a post-effective amendment to such Registration Statement
that cures such failure and that is itself declared effective (within five days
of filing such post-effective amendment to such Registration Statement) (each
such event referred to in clauses (i) through (iv), a "Registration Default"),
then the Company hereby agrees to pay to each Holder of Transfer Restricted
Securities affected thereby additional interest ("Additional Interest") which
will accrue and be payable at the time interest is due on the Series A Notes the
Series B Notes (in addition to the stated interest on the Series A Notes and the
Series B Notes) from and including the date such Registration Default occurs to,
but not including, the date on which the applicable Registration Statement is
filed or is declared effective, the Exchange Offer is consummated, or the
applicable Registration Statement is again declared effective or made usable.
During the time that Additional Interest is accruing continuously, the rate of
such Additional Interest shall be 0.50% per annum during the first 90-day period
and shall increase by 0.25% per annum for each subsequent 90-day period, but in
no event shall such rate exceed 1.50% per annum in the aggregate regardless of
the number of Registration Defaults. If, after the cure of all Registration
Defaults then in effect, there is a subsequent Registration Default, the rate of
Additional Interest for such subsequent Registration Default shall initially be
0.50%, regardless of the Additional Interest rate in effect with respect to any
prior Registration Default at the time of the cure of such Registration Default.

     All accrued Additional Interest shall be paid by the Company to the Holders
entitled thereto in the same manner and on the same date as interest payments on
the Notes, as more fully described in the Indenture. Notwithstanding the fact
that any securities for which Additional Interest are due cease to be Transfer
Restricted Securities, all obligations of the Company to pay Additional Interest
with respect thereto shall survive until such time as such obligations with
respect to such securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

     (a) Exchange Offer Registration Statement. In connection with the Exchange
Offer, the Company shall (x) comply with all applicable provisions of Section
6(c) below, (y) use its reasonable best efforts to effect such exchange and to
permit the resale of Series B Notes by Broker-Dealers that tendered in the
Exchange Offer Series A Notes that such Broker-Dealer acquired for its own
account as a result of its market making activities or other trading activities
(other than Series A Notes acquired directly from the Company or any of its
Affiliates) being sold in accordance with the intended method or methods of
distribution thereof, and (z) comply with all of the following provisions:



                                       9
<PAGE>

          (i) If, following the date hereof there has been announced a change in
     Commission policy with respect to exchange offers such as the Exchange
     Offer, that in the reasonable opinion of counsel to the Company raises a
     substantial question as to whether the Exchange Offer is permitted by
     applicable federal law, the Company hereby agrees to seek a no-action
     letter or other favorable decision from the Commission allowing the Company
     to Consummate an Exchange Offer for such Transfer Restricted Securities
     (unless in the reasonable opinion of counsel to the Company, the filing of
     such no-action letter is not appropriate). The Company hereby agrees to
     pursue the issuance of such a decision to the Commission staff level. In
     connection with the foregoing, the Company hereby agrees to take all such
     other actions as may be requested by the Commission or otherwise required
     in connection with the issuance of such decision.

          (ii) As a condition to its participation in the Exchange Offer, each
     Holder of Transfer Restricted Securities (including, without limitation,
     any Holder who is a Broker-Dealer) shall furnish, upon the request of the
     Company, prior to the Consummation of the Exchange Offer, a written
     representation to the Company (which may be contained in the letter of
     transmittal contemplated by the Exchange Offer Registration Statement) to
     the effect that (A) it is not an Affiliate of the Company, (B) it is not
     engaged in, and does not intend to engage in, and has no arrangement or
     understanding with any person to participate in, a distribution of the
     Series B Notes to be issued in the Exchange Offer and (C) it is acquiring
     the Series B Notes in its ordinary course of business. As a condition to
     its participation in the Exchange Offer each Holder using the Exchange
     Offer to participate in a distribution of the Series B Notes shall
     acknowledge and agree that, if the resales are of Series B Notes obtained
     by such Holder in exchange for Series A Notes acquired directly from the
     Company or an Affiliate thereof, it (1) could not, under Commission policy
     as in effect on the date of this Agreement, rely on the position of the
     Commission enunciated in Morgan Stanley and Co., Inc. (available June 5,
     1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as
     interpreted in the Commission's letter to Shearman & Sterling dated July 2,
     1993, and similar no-action letters (including, if applicable, any
     no-action letter obtained pursuant to clause (i) above), and (2) must
     comply with the registration and prospectus delivery requirements of the
     Act in connection with a secondary resale transaction and that such a
     secondary resale transaction must be covered by an effective registration
     statement containing the selling security holder information required by
     Item 507 or 508, as applicable, of Regulation S-K.

          (iii) Prior to effectiveness of the Exchange Offer Registration
     Statement, the Company shall provide a supplemental letter to the
     Commission (A) stating that the Company is registering the Exchange Offer
     in reliance on the position of the Commission enunciated in Exxon Capital
     Holdings Corporation (available May 13, 1988),



                                       10
<PAGE>

     Morgan Stanley and Co., Inc. (available June 5, 1991) as interpreted in the
     Commission's letter to Shearman & Sterling dated July 2, 1993, and, if
     applicable, any no-action letter obtained pursuant to clause (i) above, (B)
     including a representation that the Company has not entered into any
     arrangement or understanding with any Person to distribute the Series B
     Notes to be received in the Exchange Offer and that, to the best of the
     Company's information and belief, each Holder participating in the Exchange
     Offer is acquiring the Series B Notes in its ordinary course of business
     and has no arrangement or understanding with any Person to participate in
     the distribution of the Series B Notes received in the Exchange Offer and
     (C) any other undertaking or representation required by the Commission as
     set forth in any no-action letter obtained pursuant to clause (i) above, if
     applicable.

     (b) Shelf Registration Statement. In connection with the Shelf Registration
Statement, the Company shall:

          (i) comply with all the provisions of Section 6(c) below and use its
     reasonable best efforts to effect such registration to permit the sale of
     the Transfer Restricted Securities being sold in accordance with the
     intended method or methods of distribution thereof (as indicated in the
     information furnished to the Company pursuant to Section 4(b) hereof), and
     pursuant thereto the Company will prepare and file with the Commission a
     Registration Statement relating to the registration on any appropriate form
     under the Act, which form shall be available for the sale of the Transfer
     Restricted Securities in accordance with the intended method or methods of
     distribution thereof within the time periods and otherwise in accordance
     with the provisions hereof, and

          (ii) issue, upon the request of any Holder or purchaser of Series A
     Notes covered by any Shelf Registration Statement contemplated by this
     Agreement, Series B Notes having an aggregate principal amount equal to the
     aggregate principal amount of Series A Notes sold pursuant to the Shelf
     Registration Statement and surrendered to the Company for cancellation; the
     Company shall register Series B Notes on the Shelf Registration Statement
     for this purpose and issue the Series B Notes to the purchasers of
     securities subject to the Shelf Registration Statement in the names as such
     purchasers shall designate.

     (c) General Provisions. In connection with any Registration Statement and
any related Prospectus required by this Agreement, the Company shall:

          (i) use its reasonable best efforts to keep such Registration
     Statement continuously effective and provide all requisite financial
     statements for the period specified in Section 3 or 4 of this Agreement, as
     applicable. Upon the occurrence of any event that would cause any such
     Registration Statement or the Prospectus contained



                                       11
<PAGE>

     therein (A) to contain an untrue statement of material fact or omit to
     state any material fact necessary to make the statements therein not
     misleading or (B) not to be effective and usable for resale of Transfer
     Restricted Securities during the period required by this Agreement, the
     Company shall file promptly an appropriate amendment to such Registration
     Statement curing such defect, and, if Commission review is required, use
     its reasonable best efforts to cause such amendment to be declared
     effective as soon as practicable.

          (ii) prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such Registration Statement effective for the
     applicable period set forth in Section 3 or 4 hereof, as the case may be;
     cause the Prospectus to be supplemented by any required Prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
     under the Act in a timely manner; and comply with the provisions of the Act
     with respect to the disposition of all securities covered by such
     Registration Statement during the applicable period in accordance with the
     intended method or methods of distribution by the sellers thereof set forth
     in such Registration Statement or supplement to the Prospectus;

          (iii) advise each selling Holder and each Initial Purchaser who is
     required to deliver a prospectus in connection with sales or market making
     activities (an "Affiliated Market Maker") promptly and, if requested by
     such Person, confirm such advice in writing, (A) when the Prospectus or any
     Prospectus supplement or post-effective amendment has been filed, and, with
     respect to any applicable Registration Statement or any post-effective
     amendment thereto, when the same has become effective, (B) of any request
     by the Commission for amendments to the Registration Statement or
     amendments or supplements to the Prospectus or for additional information
     relating thereto, (C) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement under the Act or
     of the suspension by any state securities commission of the qualification
     of the Transfer Restricted Securities for offering or sale in any
     jurisdiction, or the initiation of any proceeding for any of the preceding
     purposes, and (D) of the existence of any fact or the happening of any
     event that makes any statement of a material fact made in the Registration
     Statement, the Prospectus, any amendment or supplement thereto or any
     document incorporated by reference therein untrue, or that requires the
     making of any additions to or changes in the Registration Statement in
     order to make the statements therein not misleading, or that requires the
     making of any additions to or changes in the Prospectus in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. If at any time the Commission shall issue any
     stop order suspending the effectiveness of the Registration Statement, or
     any state securities com-



                                       12
<PAGE>

     mission or other regulatory authority shall issue an order suspending the
     qualification or exemption from qualification of the Transfer Restricted
     Securities under state securities or Blue Sky laws, the Company shall use
     its reasonable best efforts to obtain the withdrawal or lifting of such
     order at the earliest possible time;

          (iv) subject to Section 6(c)(i), if any fact or event contemplated by
     Section 6(c)(iii)(D) above shall exist or have occurred, prepare a
     supplement or post-effective amendment to the Registration Statement or
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of Transfer Restricted Securities, the Prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (v) furnish to each selling Holder and each Affiliated Market Maker,
     in connection with such sale, if any, before filing with the Commission,
     copies of any Registration Statement or any Prospectus included therein or
     any amendments or supplements to any such Registration Statement or
     Prospectus (including all documents incorporated by reference after the
     initial filing of such Registration Statement), which documents will be
     subject to the review and comment of such Persons in connection with such
     sale, if any, for a period of at least five Business Days, and the Company
     will not file any such Registration Statement or Prospectus or any
     amendment or supplement to any such Registration Statement or Prospectus
     (including all such documents incorporated by reference) to which such
     Persons shall reasonably object within five Business Days after the receipt
     thereof. Such Person shall be deemed to have reasonably objected to such
     filing if such Registration Statement, amendment, Prospectus or supplement,
     as applicable, as proposed to be filed, contains an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein not misleading or fails to comply with the applicable

     provide copies of such document to each selling Holder and each Affiliated
     Market Maker in connection with such sale, if any, make the Company's
     representatives available for discussion of such document and other
     customary due diligence matters, and include such information in such
     document prior to the filing thereof as such Persons may reasonably
     request; provided, however, that such Persons shall first agree in writing
     with the Company that any information that is reasonably and in good faith
     designated by the Company in writing as confidential at the time of
     delivery of such information shall be kept confidential by such Persons,
     unless (a) disclosure of such information is required by court or
     administrative order or is necessary to respond to inquiries of regulatory
     authorities,



                                       13
<PAGE>

     (b) disclosure of such information is required by law (including any
     disclosure requirements pursuant to federal securities laws in connection
     with the filing of such Registration Statement or the use of such
     Prospectus), (c) such information becomes generally available to the public
     other than as a result of a disclosure or failure to safeguard such
     information by such Person or (d) such information becomes available to
     such Persons from a source other than the Company and its subsidiaries and
     such source is not known, after due inquiry, by such Person to be bound by
     a confidentiality agreement; provided, further, that the foregoing
     investigation shall be coordinated on behalf of such Persons by one
     representative designated by and on behalf of such Persons and any such
     confidential information shall be available from such representative to
     such Persons so long as any Person agrees to be bound by such
     confidentiality agreement;

          (vii) make available, at reasonable times, for inspection by each
     selling Holder and each Affiliated Market Maker and any attorney or
     accountant retained by such Persons, all financial and other records,
     pertinent corporate documents of the Company and cause the Company's
     officers, directors and employees to supply all information reasonably
     requested in writing by any such Person, attorney or accountant in
     connection with such Registration Statement or any post-effective amendment
     thereto subsequent to the filing thereof and prior to its effectiveness;

          (viii) if requested by any selling Holders in connection with such
     sale or any Affiliated Market Maker, promptly include in any Registration
     Statement or Prospectus, pursuant to a supplement or post-effective
     amendment if necessary, such information as such Persons may reasonably
     request in writing to have included therein, including, without limitation,
     information relating to the "Plan of Distribution" of the Transfer
     Restricted Securities, and make all required filings of such Prospectus
     supplement or post-effective amendment as soon as practicable after the
     Company is notified of the matters to be included in such Prospectus
     supplement or post-effective amendment;

          (ix) furnish to each selling Holder in connection with such sale and
     each Affiliated Market Maker, without charge, at least one copy of the

     amendment thereto, including all documents incorporated by reference
     therein and all exhibits (including exhibits incorporated therein by
     reference);

          (x) deliver to each selling Holder and each Affiliated Market Maker,
     without charge, as many copies of the Prospectus (including each
     preliminary prospectus) and any amendment or supplement thereto as such
     Persons reasonably may request; the Company hereby consents to the use (in
     accordance with law) of the Prospectus



                                       14
<PAGE>

     and any amendment or supplement thereto by each Person in connection with
     the offering and the sale of the Transfer Restricted Securities covered by
     the Prospectus or any amendment or supplement thereto and all market making
     activities of such Affiliated Market Maker, as the case may be;

          (xi) upon the request of any Holder, enter into such agreements
     (including underwriting agreements) and make such representations and
     warranties and take all such other actions in connection therewith in order

     Securities pursuant to any applicable Registration Statement contemplated
     by this Agreement as may be reasonably requested in writing by any Holder
     in connection with any sale or resale pursuant to any applicable
     Registration Statement. In such connection, and also in connection with
     market making activities by any Affiliated Market Maker, the Company shall:

               (A) upon written request of any selling Holder or any Affiliated
          Market Maker, furnish (or in the case of paragraphs (2) and (3), use
          its reasonable best efforts to cause to be furnished) to each Person,
          upon Consummation of the Exchange Offer or upon the effectiveness of
          the Shelf Registration Statement, as the case may be:

                    (1) a certificate, dated such date, signed on behalf of the
               Company by (x) the President or any Vice President and (y) a
               principal financial or accounting officer of the Company,
               confirming, as of the date thereof, the matters set forth in
               Sections 6(z), 9(a) and 9(b) of the Purchase Agreement and such
               other similar matters as such Persons may reasonably request;

                    (2) an opinion, dated the date of Consummation of the
               Exchange Offer or the date of effectiveness of the Shelf
               Registration Statement, as the case may be, of counsel for the
               Company covering matters similar to those set forth in Section
               9(e) of the Purchase Agreement and such other matters as such
               Holder may reasonably request, and including, without limitation,
               the paragraph relating to Section 10b-5 under the Exchange Act;
               and

                    (3) On the date of Consummation of the Exchange Offer or the
               date of effectiveness of the Shelf Registration Statement, as
               applicable, customary comfort letters, dated the date of
               Consummation of the Exchange Offer, or as of the date of
               effectiveness of the Shelf Registration Statement, as the case
               may be, from the independent accountants of the Company and the
               Predecessor Division, in the customary form and covering matters
               of the type customarily covered in comfort letters to
               underwrit-



                                       15
<PAGE>

               ers in connection with underwritten offerings, and affirming the
               matters set forth in the comfort letters delivered pursuant to
               Section 9(j) of the Purchase Agreement; and

               (B) deliver such other documents and certificates as may be
          reasonably requested in writing by the such Persons to evidence
          compliance with the matters covered in clause (A) above and with any
          customary conditions contained in any agreement entered into by the
          Company pursuant to this clause (xi);

          (xii) prior to any public offering of Transfer Restricted Securities,
     cooperate with the selling Holders and their counsel in connection with the
     registration and qualification of the Transfer Restricted Securities under
     the securities or Blue Sky laws of such jurisdictions as the selling
     Holders may reasonable request in writing and do any and all other acts or
     things necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the
     applicable Registration Statement; provided, however, that the Company
     shall not be required to register or qualify as a foreign corporation where
     it is not now so qualified or to take any action that would subject it to
     the service of process in suits or to taxation, other than as to matters
     and transactions relating to the Registration Statement, in any
     jurisdiction where it is not now so subject;

          (xiii) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the Holders to facilitate the timely preparation
     and delivery of certificates representing Transfer Restricted Securities to
     be sold and not bearing any restrictive legends; and to register such
     Transfer Restricted Securities in such denominations and such names as the
     selling Holders may request in writing at least two Business Days prior to
     such sale of Transfer Restricted Securities;

          (xiv) use its reasonable best efforts to cause the disposition of the
     Transfer Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof to
     consummate the disposition of such Transfer Restricted Securities, subject
     to the proviso contained in clause (xii) above;

          (xv) provide a CUSIP number for all Transfer Restricted Securities not
     later than the effective date of a Registration Statement covering such
     Transfer Restricted Securities and provide the Trustee under the Indenture
     with printed certificates for the Transfer Restricted Securities which are
     in a form eligible for deposit with the Depository Trust Company;



                                       16
<PAGE>

          (xvi) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make generally available to
     its security holders with regard to any applicable Registration Statement,
     as soon as practicable, a consolidated earnings statement meeting the
     requirements of Rule 158 (which need not be audited) covering a
     twelve-month period beginning after the effective date of the Registration
     Statement (as such term is defined in paragraph (c) of Rule 158 under the
     Act);

          (xvii) cause the Indenture to be qualified under the TIA not later
     than the effective date of the first Registration Statement required by
     this Agreement and, in connection therewith, cooperate with the Trustee and
     the Holders to effect such changes to the Indenture as may be required for
     such Indenture to be so qualified in accordance with the terms of the TIA;
     and execute and use its best efforts to cause the Trustee to execute, all
     documents that may be required to effect such changes and all other forms
     and documents required to be filed with the Commission to enable such
     Indenture to be so qualified in a timely manner; and

          (xviii) provide promptly to each Holder and each Affiliated Market
     Maker, upon request, each document filed with the Commission pursuant to
     the requirements of Section 13 or Section 15(d) of the Exchange Act, unless
     already provided.

     (d) Restrictions on Holders. Each Holder and each Affiliated Market Maker
agrees by acquisition of a Transfer Restricted Security that, upon receipt of
the notice referred to in Section 6(c)(iii)(C) or any notice from the Company of
the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof
(in each case, a "Suspension Notice"), such Person will forthwith discontinue
disposition of Transfer Restricted Securities pursuant to the applicable
Registration Statement until (i) such Person has received copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof, or
(ii) such Person is advised in writing by the Company that the use of the
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus (in
each case, the "Recommencement Date"). Each Person receiving a Suspension Notice
hereby agrees that it will either (i) destroy any Prospectuses, other than
permanent file copies, then in such Person's possession which have been replaced
by the Company with more recently dated Prospectuses or (ii) deliver to the
Company (at the Company's expense) all copies, other than permanent file copies,
then in such Person's possession of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of the Suspension
Notice. The time period regarding the effectiveness of such Registration
Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended
by a number of days equal to the number of days in the period from and including
the date of delivery of the Suspension Notice to the date of delivery of the
Recommencement Date.

SECTION 7. REGISTRATION EXPENSES

     (a) All expenses incident to the Company's performance of or compliance
with this Agreement will be borne by the Company, regardless of whether a
Registration Statement becomes effective, including without limitation: (i) all
registration and filing fees and expenses; (ii) all fees and expenses of
compliance with federal securities and state Blue Sky or securities laws; (iii)
all expenses of printing (including printing certificates for the Series B Notes
to be issued in the Exchange Offer and printing of Prospectuses whether for
exchanges, sales, market making or otherwise), messenger and delivery services
and telephone; (iv) all fees and disbursements of counsel for the Company; (v)
all application and filing fees in connection with listing the Series B Notes on
a national securities exchange or automated quotation system pursuant to the

     The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company.

     Each Holder shall pay all underwriting discounts and commissions and
transfer taxes, if any, relating to the sale or disposition of such Holder's
Transfer Restricted Securities.

     (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company will reimburse the
Initial Purchasers and the Holders of Transfer Restricted Securities who are
tendering Series A Notes in the Exchange Offer and/or selling or reselling
Series A Notes or Series B Notes pursuant to the "Plan of Distribution"
contained in the Exchange Offer Registration Statement or the Shelf Registration
Statement, as applicable, for the reasonable fees and disbursements of not more
than one counsel with respect to matters of U.S. law and one counsel with
respect to matters of Canadian law, who shall be Latham & Watkins and Osler,
Hoskin & Harcourt, respectively, unless another firm shall be chosen by the
Holders of a majority in principal amount of the Transfer Restricted Securities
for whose benefit such Registration Statement is being prepared.

SECTION 8. INDEMNIFICATION

     (a) The Company agrees to indemnify and hold harmless each Holder, its
directors, officers and each Person, if any, who controls such Holder (within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from
and against any and all losses, claims, damages, liabilities, judgments,
(including without limitation, any legal or other ex-



                                       18
<PAGE>

penses incurred in connection with investigating or defending any matter,
including any action that could give rise to any such losses, claims, damages,
liabilities or judgments) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement,
preliminary prospectus or Prospectus (or any amendment or supplement thereto)
provided by the Company to any Holder or any prospective purchaser of Series B
Notes or registered Series A Notes, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing to the Company
by any of the Holders; provided, however, that the foregoing indemnity agreement
with respect to any preliminary prospectus, shall not inure to the benefit of
any such person who failed to deliver a Prospectus (so long as the Prospectus
was provided by the Company to such person in the requisite quantity and on a
timely basis to permit proper delivery) to the person asserting any losses,
claims, damages, liabilities or judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in the preliminary
prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if such material misstatement or omission or alleged
material misstatement or omission was cured in the Prospectus.

     (b) Each Holder of Transfer Restricted Securities agrees, severally and not
jointly, to indemnify and hold harmless the Company, and its directors and
officers, and each person, if any, who controls (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Company, to the same extent
as the foregoing indemnity from the Company set forth in Section 8(a) above, but
only with reference to information relating to such Holder furnished in writing
to the Company by such Holder expressly for use in any Registration Statement.
In no event shall any Holder, its directors, officers or any Person who controls
such Holder be liable or responsible for any amount in excess of the amount by
which the total amount received by such Holder with respect to its sale of
Transfer Restricted Securities pursuant to a Registration Statement exceeds (i)
the amount paid by such Holder for such Transfer Restricted Securities and (ii)
the amount of any damages that such Holder, its directors, officers or any
Person who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

     (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to



                                       19
<PAGE>

both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys with respect to matters of U.S. law and
one separate firm of attorneys with respect to matters of Canadian law (in each
case, in addition to any local counsel) for all indemnified parties and all such
fees and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by a majority of the Holders, in the case of the parties
indemnified pursuant to Section 8(a), and by the Company, in the case of parties
indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and
hold harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty Business Days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of the indemnifying party) and, prior to the
date of such settlement, the indemnifying party shall have failed to comply with
such reimbursement request. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action 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 the indemnified party.

     (d) To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or



                                       20
<PAGE>

judgments referred to therein, then each indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or judgments (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Holders, on
the other hand, from their sale of Transfer Restricted Securities or (ii) if the
allocation provided by clause 8(d)(i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause 8(d)(i) above but also the relative fault of the Company,
on the one hand, and of the Holder, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the
Holder, on the other hand, 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, on the one hand, or by the Holder, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid or
payable by a party as a result of the losses, claims, damages, liabilities and
judgments referred to above shall be deemed to include, subject to the
limitations set forth in the second paragraph of Section 8(a), any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim.

     The Company and each Holder agree that it would not be just and equitable
if contribution pursuant to this Section 8(d) were determined by pro rata
allocation (even if the Holders 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 in the immediately preceding paragraph. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or judgments referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any matter, including any action
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any Person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of its Transfer
Restricted Securities pursuant to a Registration Statement exceeds the sum of
(i) the amount paid by such Holder for such Transfer Restricted Securities and
(ii) the amount of any damages which such Holder 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 Holders'
obligations to contribute pursuant to this Section 8(d) are several in
proportion to the re-



                                       21
<PAGE>

spective principal amount of Transfer Restricted Securities held by each Holder
hereunder and not joint.

     (e) The Company agrees that the indemnity and contribution provisions of
this Section 8 shall apply to Affiliated Market Makers to the same extent, on
the same conditions, as it applies to Holders.

SECTION 9. RULE 144A AND RULE 144

     For so long as any Notes remain outstanding, the Company shall furnish to
the Holders the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act. Whether or not the Company is subject to Section 13(a)
or 15(d) of the Exchange Act, the Company shall file with the SEC and furnish to
the Holders and the Trustee (i) within 140 days after the end of each fiscal
year, annual reports on Form 20-F or 40-F, as applicable (or any successor
form), containing the information required to be contained therein (or required
in such successor form) and (ii) (a) within 45 days after the end of each of the
first three fiscal quarters of each fiscal year, reports on Form 10-Q or (b)
within 60 days after the end of each of the first three fiscal quarters of each
fiscal year, reports on Form 6-K (or any successor form) which, regardless of
applicable requirements, shall, at a minimum, contain a "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

SECTION 10. SUBMISSION TO JURISDICTION; APPOINTMENT OF AGENT FOR SERVICE

     To the fullest extent permitted by applicable law, the Company irrevocably
submits to the jurisdiction of any federal or state court the Borough of
Manhattan in the City, County and State of New York, United States of America,
in any suit or proceeding based on or arising under this Agreement (solely in
connection with any such suit or proceeding), and irrevocably agrees that all
claims in respect of such suit or proceeding may be determined in any such
court. The Company irrevocably and fully waives the defense of an inconvenient
forum to the maintenance of such suit or proceeding. The Company agrees that
final judgment in any such suit, action or proceeding brought in such a court
shall be conclusive and binding upon the Company and may be enforced in the
courts of Canada (or any other courts to the jurisdiction of which the Company
is subject) by a suit upon such judgment, provided that service of process is
effected upon the Company in the manner specified herein. The Company hereby
irrevocably designates and appoints CT Corporation System (the "Process Agent"),
as the authorized agent of the Company upon whom process may be served in any
such suit or proceeding, it being understood that the designation and
appointment of CT Corporation System as such authorized agent shall become
effective immediately without any further action on the part of the Company. The
Company represents to the Initial Purchasers that it has notified the Process
Agent of such designation and appointment and that the Process Agent has
accepted the same in writing. The Company hereby irrevocably authorizes and
directs the Process Agent to accept such service.



                                       22
<PAGE>

The Company further agrees that, to the extent permitted by law, service of
process upon the Process Agent and written notice of said service to the Company
mailed by prepaid registered first class mail at its address specified in
Section 12 of this Agreement, shall be deemed in every respect effective service
of process upon the Company in any such suit or proceeding. Nothing herein shall
affect the right of any Initial Purchaser or Affiliated Market Maker or any
person controlling such Initial Purchaser or Affiliated Market Maker or any
Indemnified Holder to serve process in any other manner permitted by law. The
Company further agrees to take any and all action, including the execution and
filing of any and all such documents and instruments as may be necessary to
continue such designation and appointment of the Process Agent in full force and
effect so long as the Company has any outstanding obligations under this
Agreement. To the extent that the Company has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service of note, attachment prior to judgment, attachment in aid of
execution, executor or otherwise) with respect to itself or its property, the
Company hereby irrevocably waives such immunity in respect of their obligations
under this Agreement, to the extent permitted by law.

     The provisions of this Section 10 shall survive any termination of this
Agreement, in whole or in part.

SECTION 11. OBLIGATION CURRENCY

     The obligation of the parties to make payments hereunder is in U.S. dollars
(the "Obligation Currency") and such obligation shall not be discharged or
satisfied by any tender or recovery pursuant to any judgment expressed in or
converted into any currency other than the Obligation Currency or any other
realization in such other currency, whether as proceeds of set-off, security,
guarantee, distributions, or otherwise, except to the extent to which such
tender, recovery or realization shall result in the effective receipt by the
party which is to receive such payment of the full amount of the Obligation
Currency expressed to be payable hereunder, and the party liable to make such
payment agrees to indemnify the party which is to receive such payment (as an
additional, separate and independent cause of action) for the amount (if any) by
which such effective receipt shall fall short of the full amount of the
Obligation Currency expressed to be payable hereunder and such obligation to
indemnify shall not be affected by judgment being obtained for any other sums
due under this Agreement.

SECTION 12. MISCELLANEOUS

     (a) Remedies. The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under Sections 3 and 4 hereof may result
in material irreparable injury to the Initial Purchasers or the Holders or
Affiliated Market Makers for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, the Initial Purchasers or any Holder or
Affiliated Market Maker may obtain such relief as may be required to
specifically



                                       23
<PAGE>

enforce the Company's obligations under Sections 3 and 4 hereof. The Company
further agrees to waive the defense in any action for specific performance that
a remedy at law would be adequate.

     (b) No Inconsistent Agreements. The Company will not, on or after the date
of this Agreement, enter into any agreement with respect to its securities that
is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Except for the rights granted
pursuant to the Registration Rights Agreement dated December 23, 1998, among the
Company, Donaldson, Lufkin & Jenrette Securities Corporation and TD Securities
(USA) Inc., the Company has not previously entered into any agreement granting
any registration rights with respect to its securities to any Person. The rights
granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof.

     (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 10(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

     (d) Third Party Beneficiary. The Holders and Affiliated Market Makers shall
be third party beneficiaries to the agreements made hereunder between the
Company, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders and Affiliated Market Makers hereunder.

     (e) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air

transfer or other disposition of Transfer Restricted Securities in violation of
the terms hereof or of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such

                              W I T N E S S E T H :


     WHEREAS, the Corporation wishes to sell to the Investors, and the Investors
wish to purchase from the Corporation, shares of a newly created series of

Amendment of the Corporation in the form included in Schedule A hereto (the
"Articles of Amendment").

     ACCORDINGLY, the parties hereto hereby agree as follows:

     SECTION 1. Issuance and Sale of Preferred Shares.

     1.1. The Purchase. (a) Subject to the terms and conditions set forth in
this Agreement, at the Closing, each Investor shall, severally and not jointly,
purchase from the Corporation and the Corporation shall issue to each Investor,
the number of Series A Non-Voting Preferred Shares set forth opposite such
Investor's name on Schedule 1.1 (the "Purchase"), subject to adjustment as set
forth in Section 1.4, at the purchase price set forth opposite such Investor's
name on Schedule 1.1. The aggregate purchase price to be paid by the Investors

Agreement, the closing of the Purchase (the "Closing") shall take place at the
offices of Fried, Frank, Harris, Shriver & Jacobson, One New York Plaza, New

     1.3. Deliveries at the Closing. (a) At the Closing, the Corporation shall

Investor of the Purchase Price, which shall be paid by wire transfer to an
account designated at least one Business Day prior to the Closing by the
Corporation.

     (b) At the Closing, the Corporation will deliver to the Investors, and the
Investors will deliver to the Corporation, the various certificates, instruments
and documents referred to in Section 6 below.

     1.4. Purchase Price Adjustment. (a) In addition to, and without limitation
of all other indemnities in this Agreement, as a protection to the Investors
against the existence of issued shares or other securities of the Corporation
not disclosed in Section 2.3, in the event that, at any time, the representation
and warranty set forth in Section 2.3(c) is determined to have been incorrect as
of the Closing, the Corporation shall issue to the Investors (on a pro rata
basis, based upon the amount of each Investor's original investment), at no
additional cost to the Investors, and as an adjustment to the purchase price
(whether under this paragraph (a) or paragraphs (b) or (c) of this Section 1.4,
a "Purchase Price Adjustment") paid by the Investors per Series A Non-Voting
Preferred Share, an additional amount of Series A Non-Voting Preferred Shares
such that, if such issuance of additional Series A Non-Voting Preferred Shares
had been made at Closing, such representation and warranty would have been true
and accurate in all respects.

     (b) If at any time after the Closing, the Corporation shall either: (i)
subject to paragraph (f) of this Section 1.4, issue any Employee Shares (other
than (x) Common Shares issued upon the exercise of stock options listed as
Common Share Equivalents on Schedule 2.3(b)(ii) (i.e., [      ]* options granted

Plan (Amended) (the "1998 Plan") (the "Existing 10% Option Pool")) or (y) Common
Shares issued upon the exercise of stock options granted under the New 5% Option
Pool (as defined below) to the extent the grant of such stock options as
Employee Shares previously resulted in an adjustment under this Section 1.4(b)),
Deemed Outstanding Shares, Permitted Reissued Options or Common Shares issued
upon the exercise of Permitted Reissued Options) or (ii) issue any Minority
Roll-Up Shares (except Minority Roll-Up shares issued after September 7, 2000),
then the Corporation shall (in the case of clause (i), at the end of each
calendar quarter (unless otherwise requested by any Investor), and in the case
of clause (ii) immediately) issue to the Investors (on a pro rata basis, based
upon the amount of each Investor's original investment), at no additional cost
to the Investors, and as a Purchase Price Adjustment, a number of Series A
Non-Voting Preferred Shares per each Series A Non-Voting Preferred Share equal

of the amount of Series A Non-Voting Preferred Shares which would have been
issued with respect to such Purchase Price Adjustment pursuant to Section 1.4(a)
or Section 1.4(b) treating for purposes of such Purchase Price Adjustment the
Series A Non-Voting Preferred Shares as not having been converted into Common
Shares.

     (d) Any additional Series A Non-Voting Preferred Shares and Common Shares

distributions which would have accrued or have been payable with respect to and
the application of any anti-dilution, ratable treatment or similar provisions as
set forth in the Articles of Amendment, applicable law or otherwise which would
have been applicable to such Series A Non-Voting Preferred Shares and Common
Shares had they been issued on the date hereof.

split, stock dividend, combination, reorganization, reclassification or other
similar event involving Common Shares).

qualified to transact business as an extra-provincial corporation or foreign
corporation in, and is in good standing under the laws of, those jurisdictions
listed on Schedule 2.1(a) in square brackets opposite its name, which
jurisdictions constitute all of the jurisdictions wherein the character of the
property owned or leased or the nature of the activities conducted by it makes
such qualification necessary except where the failure to be so qualified would
not have a material adverse effect on the business, prospects, condition
(financial or otherwise), operations, properties, assets or liabilities of the
WFI Entities taken as a whole (a "Material Adverse Effect"). For all purposes of
this Agreement, the business, prospects, conditions (financial or otherwise),
operations, properties, assets or liabilities of the WFI Entities shall be
deemed to include the business, prospects, condition (financial or otherwise),
operations, properties, assets and liabilities associated with the Fiber Assets
(and the rights, liabilities and obligations associated with the Fiber Assets)
as defined in the Ledcor Roll-Up Agreement.

described in Part 1 of Schedule 2.22(a) are currently held by or on behalf of
the appropriate WFI Entity or its contractor(s) and are all the Permits
necessary to operate the Network as it presently is operated except where the
failure to have such Permits would not have a Material Adverse Effect. The
Permits identified in Schedule 2.20(a) and Part 1 and Part 2 of Schedule 2.22(a)
together with licenses and permits which will be required in connection with the
Corporation's business plan to sell telecommunications services are all of the

not have a Material Adverse Effect. With respect to (i) the matters set forth on
Schedule 2.22(b) and (ii) the Hibernia Project, the WFI Entities have obtained
or intend to timely file for or obtain the right to use or to enjoy the use of

withholding tax is imposed on such distribution, redemption or other payment,
the indemnity provided for in the preceding sentence shall be satisfied by the
payment by the Corporation, at the same time as the making of such distribution,
redemption or other payment, of additional amounts as necessary so that the net
amount received by each Investor is the same as it would have received had no
such withholding tax been imposed. In any other case, the indemnity shall be
satisfied by payment in cash no later than three business days following demand
therefor (which demand shall be accompanied by a statement setting forth the
basis for indemnification). The Corporation shall not be obligated to indemnify
and hold an Investor harmless pursuant to this Section 5.4 in respect of (i) any
deemed dividend arising by virtue of


                                      -34-


<PAGE>

the application of subsection 212.1(1) of the Income Tax Act (Canada), (ii) any
deemed dividend arising solely by virtue of the application of 84(3) of the
Income Tax Act (Canada) in respect of a sale to or a redemption by the
Corporation of Common Shares pursuant to an offer made by the Corporation to
purchase through the facilities of The Toronto Stock Exchange in a particular
twelve-month period not more than 5% of a particular class of Common Shares
issued and outstanding at the commencement of such twelve-month period, which
offer is completed in compliance with applicable Canadian Securities Laws and
the rules of The Toronto Stock Exchange, (iii) any income tax liability arising
from a capital gain; or (iv) any tax arising if any Investor holds or is deemed
to hold the Preferred Shares or Common Shares in carrying on a business in
Canada. The Corporation shall indemnify and hold each Investor harmless from and
against any income tax liability imposed by the jurisdiction in which such
Investor is organized or otherwise resident, which income tax liability is
imposed on or in respect of any payment made under this Section 5.4.

     (b) In the event that any Investor shall be entitled to receive a refund of
tax or a credit against or relief or remission for, or repayment of, any tax
paid or payable by it (collectively, a "Tax Credit") in respect of or calculated
with reference to the withholding tax liability giving rise to the requirement
of the Corporation to make an indemnity payment under this Section 5.4, such
Investor shall use reasonable efforts to obtain the Tax Credit, and upon receipt
of such Tax Credit, to the extent that it can do so without prejudice to the
retention of the amount of such Tax Credit, pay or cause to be paid to the
Company such amount as such Investor shall have concluded, acting reasonably, to
be the after-tax value to it of the Tax Credit which is attributable to the
relevant withholding tax liability. Nothing herein contained shall interfere
with the right of each Investor to arrange its tax affairs in whatever manner it
thinks fit or require any Investor to disclose to the Company any information
regarding its tax affairs or tax calculations. Such payments shall be made
promptly upon the relevant Investor certifying that the amount of such credit,
relief, remission or repayment has been received by it and each Investor
undertake so to certify or cause to be certified promptly upon such receipt.
Notwithstanding anything to the contrary in this Agreement, the term "Investor"
as used in this Section 5.4(b) shall refer only to the direct holder of the
shares or other property in respect of which the indemnity payment was made and
not to any holder of an interest in such direct holder or any other Person.

     (c) Notwithstanding anything to the contrary in Section 5.4(a), the
Corporation shall indemnify and hold each Investor harmless from and against all
loss incurred or suffered, directly or indirectly, by an Investor in respect of
or otherwise attributable to any additional liability for Taxes arising to the
Corporation or to an Investor as a result of the reorganization of capital
undertaken by the Corporation prior to or at Closing (the "Reorganization"). For
greater certainty, the Reorganization includes the following transactions
contemplated by the Corporation: the issuance of Series C Redeemable Preferred
Shares by the Corporation to Worldwide Fiber Holdings Ltd. ("WFH") as a stock
dividend, the disposition by WFH of all of its common shares to the Corporation
for additional Series C Redeemable Preferred Shares and for Class B Subordinate
Voting Shares, the joint election to be made by the Corporation and WFH pursuant
to subsection 85(1) of the Income Tax Act


                                      -35-

(Canada) in respect of such disposition, and the redemption by the Corporation
of the Series C Redeemable Preferred Shares held by WFH.

     5.5. Roll-Up Transactions. The Corporation agrees that each of the Minority
Roll-Up Transactions (as defined in Section 1.4(b)) shall be consummated in
consideration solely for the issuance of Common Shares (and not cash or any
other assets or obligations of the Corporation or any of its Subsidiaries or
affiliates). The Corporation also agrees that the Ledcor Roll-Up Agreement (as
defined in Section 1.4(b)) shall be consummated in consideration solely for the
issuance of 4,500,000 Common Shares (and not cash or any other assets or
obligations of the Corporation or any of its Subsidiaries or affiliates) and in
accordance with the terms of the Ledcor Roll-Up Agreement in effect on the date
hereof.

2.20, 2.21, 2.22, and 2.36 shall survive the Closing indefinitely and (y) the

shall survive the Closing until the expiration of all applicable statutes of
limitations. All statements contained in any certificate or other instrument

agreements and


                                      -39-


<PAGE>

     SECTION 11. Indemnification.

     11.1. General Indemnification. The Corporation shall indemnify, defend and
hold each Investor, its affiliates, and each of their respective officers,
directors, partners, managing directors, affiliates, employees, agents,
consultants, representatives, successors and assigns (each an "Investor Entity")
harmless from and against all Losses (as defined below) incurred or suffered by
an Investor Entity (whether incurred or suffered directly or indirectly through
ownership of Series A Non-Voting Preferred Shares or Conversion Shares) arising
out of, relating to, or resulting from (a) any breach of any of the
representations, warranties, covenants or agreements made by it in this
Agreement or in any agreement, certificate or other instrument delivered
pursuant hereto including, without limitation, the Documents, and (b) any third
party claim made against an Investor Entity relating to any transaction by the
Corporation financed in whole or in part, directly or indirectly, with proceeds
from the sale of any of the Series A Non-Voting Preferred Shares or Common
Shares hereunder. Each Investor, severally and not jointly, shall indemnify,
defend and hold the Corporation, its affiliates, and each of their respective
officers, directors, employees, agents, consultants, representatives, successors
and assigns harmless against all


                                      -40-


<PAGE>

Losses arising from the breach of any of its representations, warranties,
covenants or agreements in this Agreement or in any certificate or other
instrument delivered pursuant hereto, including, without limitation, the
Documents. Notwithstanding anything to the contrary in this Agreement, no
indemnification payment by the Corporation pursuant to this Section 11 with
respect to any Losses otherwise payable hereunder as a result of a breach of its
representations and warranties (other than any Losses resulting from breaches of
the representations and warranties in Section 2.7, as they relate to Taxes,
Sections 2.26 and 2.27, to any covenants contained in this Agreement or any
other Document and to willful misrepresentation, fraud or deceit, which shall
not be subject to the Deductible or Limit) shall be payable (a) until the time
as such Losses shall aggregate (on a cumulative basis and not on a per item
basis) for all Investor Entities more than US$5,000,000 (the "Deductible"), and
then only to the extent that such Losses, in the aggregate for all Investors,
exceed the Deductible; or (b) with respect to the Investor Entities associated
with each Investor, in an aggregate amount in excess of the Purchase Price of
the shares issued to such Investor or its predecessors in interest as shown on
Schedule 1.1 hereto (as increased by the amounts by which the Series A
Non-Voting Liquidation Value, as defined in the Terms of the Series A Non-Voting
Preferred Shares, Series A in the Articles of Amendment, would increase from the
Closing Date to the date of determination) (the "Limit"). The Corporation shall
also indemnify, defend and hold harmless each Investor Entity against any and
all Losses (as defined in Section 11.2 and not subject to any Deductible or
Limit) arising under Title IV of ERISA, Section 302 of ERISA and Sections 412
and 4971 of the Code which may be incurred by any of them arising out of or
relating to any WFI Entity being or having been an ERISA Affiliate with any
other Person (other than another WFI Entity), whether such Losses arise out of
or relate to any event or state of facts occurring or existing before, on or
after the Closing Date.

     An "ERISA Affiliate" is defined as any entity that is (i) a member of a
"controlled group of corporations," under "common control" or a member of an
"affiliated service group" within the meaning of Section 414(b), (c) or (m) of
the Code, (ii) required to be aggregated under Section 414(o) of the Code, or
(iii) under "common control," within the meaning of Section 4001(a)(14) of
ERISA, or any regulations promulgated or proposed under any of the foregoing
Sections, in each case with any WFI Entity.

     11.2. Indemnification Principles. For purposes of this Section 11, "Losses"
shall mean each and all of the following items: claims, losses (including,
without limitation, losses of earnings), liabilities, obligations, payments,
damages (actual, punitive or consequential), charges, judgments, fines,
penalties, amounts paid in settlement, costs and expenses (including, without
limitation, interest which may be imposed in connection therewith), costs and
expenses of investigation, actions, suits, proceedings, demands, assessments and
fees, expenses and disbursements of counsel, consultants and other experts. For
purposes of Section 11.1(a) the Corporation shall not be obligated to indemnify,
defend or hold harmless any Investor Entity for any (i) punitive damages or (ii)
damages arising out of such Investor Entity's lost use of such Investor Entity's
share of the Purchase Price (as shown on Schedule 1.1 hereto) for an alternative
investment, except in any case where such damages are the result of the willful
misrepresentation, fraud or deceit of the


                                      -41-


<PAGE>

Corporation. Any indemnification payment by the Corporation to any Investor
pursuant to this Section 11 shall include an additional amount so that the
Investor does not, directly or indirectly, bear any portion of such payment made
by the Corporation with respect to such payment on account of the Investor's
direct or indirect investment in the Corporation as contemplated by the
Purchase. Any payment by the Corporation to an Investor pursuant to this Section
11, shall be treated for federal income tax purposes as a Purchase Price
Adjustment.

     11.3. Claim Notice. A party seeking indemnification under this Section 11
shall, promptly upon becoming aware of the facts indicating that a claim for
indemnification may be warranted, give to the party from whom indemnification is
being sought a claim notice relating to such Loss (a "Claim Notice"). Each Claim
Notice shall specify the nature of the claim, the applicable provision(s) of
this Agreement or other instrument under which the claim for indemnity arises,
and, if possible, the amount or the estimated amount thereof. No failure or
delay in giving a Claim Notice (so long as the same is given prior to expiration
of the representation or warranty upon which the claim is based) and no failure
to include any specific information relating to the claim (such as the amount or
estimated amount thereof) or any reference to any provision of this Agreement or
other instrument under which the claim arises shall affect the obligation of the
party from whom indemnity is sought except to the extent such party is
materially prejudiced thereby.

     11.4. Claim Procedure.

     (a) Procedure for Indemnification with Respect to Third-Party Claims. If
any indemnified party hereunder determines to seek indemnification under this
Section 11 with respect to Losses resulting from the assertion of liability by
third parties, such indemnified party shall give notice to the indemnifying
party hereunder within 30 days of such indemnified party becoming aware of any
such Losses or of facts upon which any claim for such Losses will be based; the
notice shall set forth such material information with respect thereto as is then
reasonably available to such indemnified party. In case any such liability is
asserted against such indemnified party, and such indemnified party notifies the
indemnifying party thereof, the indemnifying party will be entitled, if it so
elects by written notice delivered to such indemnified party within 10 days
after receiving such indemnified party's notice, to assume the defense thereof
with counsel satisfactory to such indemnified party, in which case, the
indemnifying party will not be liable to the indemnified party under this
Section 11.4 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
following sentence or (ii) the indemnifying party shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action, in each of
which cases the fees and expenses of counsel shall be at the expense of the
indemnifying party. Notwithstanding the foregoing, (i) such indemnified party
shall also have the right to employ its own counsel in any such case, but the
fees and expenses of such counsel shall be at the expense of such indemnified
party unless such indemnified party shall reasonably determine that there is a
conflict of interest between or among such indemnified party and the
indemnifying party with re-


                                      -42-


<PAGE>

spect to such claim, in which case the fees and expenses of such counsel will be
borne by the indemnifying party, (ii) such indemnified party shall not have any
obligation to give any notice of any assertion of liability by a third party
unless such assertion is in writing, (iii) the rights of such indemnified party
to be indemnified hereunder in respect of any Losses that may or do result from
the assertion of liability by third parties shall not be adversely affected by
its failure to give notice pursuant to the foregoing unless, and, if so, only to
the extent that, the indemnifying party is materially prejudiced thereby, and
(iv) the indemnifying party's obligations to such indemnified party under this
Section 11 shall not terminate until such indemnified party's claims have been
finally satisfied to such indemnified party's sole satisfaction. In the event
that the indemnifying party, within 10 days after receipt of the aforesaid
notice of a claim hereunder, fails to assume the defense of such indemnified
party against such claim, such indemnified party shall have the right to
undertake the defense, compromise, or settlement of such action on behalf of and
for the account, expense, and risk of the indemnifying party.

     Notwithstanding anything in this Section 11 to the contrary, (i) if there
is a reasonable probability that a claim may materially adversely affect such
indemnified party, such indemnified party shall have the right to participate in
such defense, compromise, or settlement and the indemnifying party shall not,
without such indemnified party's written consent (which consent shall not be
unreasonably withheld), settle or compromise any of such claims, or consent to
entry of any judgment in respect thereof unless such settlement, compromise, or
consent includes as an unconditional term thereof the giving by the claimant or
the plaintiff to such indemnified party a release from all liability in respect
of such claim. With respect to any assertion of liability by a third party that
results in any claim for indemnification hereunder, the parties hereto shall
make available to each other all relevant information in their possession
material to any such assertion.

     (b) Procedure For Indemnification with Respect to Non-Third Party Claims.
In the event that an indemnified party asserts the existence of a claim with
respect to Losses (but excluding claims resulting from the assertion of
liability by third parties), it shall give written notice to the indemnifying
party. Such written notice shall state that it is being given pursuant to this
Section 11.4(b), specify the nature and amount of the claim asserted, and
indicate the date on which such assertion shall be deemed accepted and the
amount of the claim deemed a valid claim (such date to be established in
accordance with the next sentence). If the indemnifying party, within 30 days
after the mailing of notice by such indemnified party, shall not give written
notice to such indemnified party announcing its intent to contest such assertion
of such indemnified party, such assertion shall be deemed accepted and the
amount of claim shall be deemed a valid claim. In the event, however, that the
indemnifying party contests the assertion of a claim by giving such written
notice to such indemnified party within said period, then the parties shall act
in good faith to reach agreement regarding such claim. In the event that
litigation shall arise with respect to any such claim, the prevailing party
shall be entitled to reimbursement of costs and expenses incurred in connection
with such litigation including attorney fees, if the parties hereto, acting in
good faith, cannot reach agreement with respect to such claim within ten days
after such notice.


                                      -43-

     SECTION 12. Remedies. In case any one or more of the covenants and/or
agreements set forth in this Agreement shall have been breached by the
Corporation, each Investor may proceed to protect and enforce its rights either
by suit in equity and/or by action at law, including, but not limited to, an
action for damages as a result of any such breach and/or an action for specific
performance of any such covenant or agreement contained in this Agreement, and
to exercise all other rights existing in their favor. The parties hereto agree
and acknowledge that money damages may not be an adequate remedy for any breach
of the provisions of this Agreement and that each party may in its sole
discretion apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive relief (without posting a bond or other
security) in order to enforce or prevent any violation of the provisions of this
Agreement.

     SECTION 13. Further Assurances. At any time or from time to time after the
Closing, the Corporation, on the one hand, and each Investor, on the other hand,
agree to cooperate with each other, and at the request of the other party, to
execute and deliver any further instruments or documents and to take all such
further action as the other party may reasonably request in order to evidence or
effectuate the consummation of the transactions contemplated hereby relating to
the Purchase and to otherwise carry out the intent of the parties hereunder.

     SECTION 14. Successors and Assigns. This Agreement shall bind and inure to
the benefit of the Corporation and the Investors and the respective successors,
Permitted Assigns, heirs and personal representatives of the Corporation and the
Investors. In addition, and whether or not any express assignment has been made,
except as otherwise expressly stated in this Agreement, the provisions of this
Agreement which are for each of the Investor's benefit as a purchaser or holder
of Transaction Securities are also for the benefit of, and enforceable by, any
permitted subsequent holder of such Transaction Securities. The parties
acknowledge that, subject to compliance with applicable securities laws, each
Investor may transfer and assign all or a part of its rights and obligations
under this Agreement to one or more other partnerships, corporations, trusts or
other organizations which have been created by, or are controlled by, control or
are under common control with such Investor or one or more of the current
partners, members or other equity holders of such Investor, without the consent
of the Corporation (collectively, "Permitted Assigns"). This Agreement shall not
be assignable by the Corporation, without the consent of each of the Investors.

     SECTION 15. Entire Agreement. This Agreement and the other writings
referred to herein or delivered pursuant hereto which form a part hereof contain
the entire agreement among the parties with respect to the subject matter hereof
and supersede all prior and contemporaneous arrangements or understandings with

<PAGE>


                                      -10-


Sale pursuant to Section 3(a), shall be consummated only in accordance with the
following procedures:

     (a) The Selling Shareholder shall first deliver to the Corporation and each
of the Other Shareholders a written notice (a "Section 4 Offer Notice"), which
shall (i) state the Selling Shareholder's intention to sell Shares to one or
more Persons (with no obligation (except in the case of a Sale that is permitted
only under the provision of Section 3(a)(ii) in which case the proposed
purchaser shall be identified) to identify or theretofore have identified the
name of such Person or Persons or to have negotiated a transaction with respect
to the Sale of such Shares), the amount and type of Shares to be sold (the
"Subject Shares"), the purchase price therefor and a summary of the other
material terms of the proposed Sale, and (ii) offer the Corporation and the
Other Shareholders the option to acquire all or a portion of such Subject Shares
upon the same terms and subject to the same conditions of the proposed Sale as
set forth in the Section 4 Offer Notice (the "Section 4 Offer"), provided that
such Section 4 Offer may require that it must be accepted by the Corporation and
the Other Shareholders on an all or nothing basis (an "All or Nothing Sale").
The Section 4 Offer shall remain open and irrevocable for the periods set forth
below (and, to the extent the Section 4 Offer is accepted during such periods,
until the consummation of the Sale contemplated by the Section 4 Offer). The
Corporation shall have the right and option, but not the obligation, for a
period of 30 days after delivery of the Section 4 Offer Notice (the "Section
4(a) Acceptance Period"), to accept all or any part of the Subject Shares at the
purchase price and on the terms stated in the Section 4 Offer Notice on its own
behalf or on behalf of a nominee of the Corporation that has been approved for
such purposes in writing by a Supermajority (a "Permitted Nominee"); provided,
however, that, if the Section 4 Offer contemplated an All or Nothing Sale and
only a part of the Subject Shares is accepted by the Corporation (or its
Permitted Nominee) during the Section 4(a) Acceptance Period, such acceptance
shall be subject to the acceptance of the Other Shareholders, pursuant to
Section 4(b), of the remaining Subject Shares. Notice of the Corporation's
intention to accept a Section 4 Offer, in whole or in part, shall be evidenced
by a writing signed by the Corporation (the "Section 4(a) Acceptance Notice")
and delivered to the Selling Shareholder and Other Shareholders prior to the end
of the Section 4 Acceptance Period, setting forth the number and type of Shares
that the Corporation elects to acquire.

     (b) If the Corporation or its Permitted Nominee, as the case may be, (i)
shall fail to accept all of the Subject Shares offered for sale pursuant to the
Section 4 Offer, (ii) shall reject in writing the Section 4 Offer, or (iii)
shall fail to respond to a Section 4 Offer Notice prior to the expiration of the
Section 4(a) Acceptance Period, then, upon the earlier of the expiration of the
Section 4(a) Acceptance Period, the giving of the Section 4(a) Acceptance Notice
and the giving of written notice of rejection by the Corporation, each Other
Shareholder shall have the right and option, for a period of 15 days thereafter
(the "Section


<PAGE>


                                      -11-


4(b) Acceptance Period"), to accept all or any part of the Subject Shares so
offered and not accepted by the Corporation or its Permitted Nominee, as the
case may be (the "Refused Shares") at the purchase price and on the terms stated
in the Section 4 Notice; provided, however, that, if the Section 4 Offer
contemplated an All or Nothing Sale, the Other Shareholders, in the aggregate,
may accept, during the Section 4(b) Acceptance Period, the Subject Shares which,
when taken together with the Subject Shares accepted by the Corporation pursuant
to Section 4(a), if any, constitute all, but not less than all, of the Subject
Shares, at the purchase price and on the terms stated in the Section 4 Offer
Notice. Such acceptance shall be made by delivering a written notice to the
Corporation and the Selling Shareholder within the Section 4(b) Acceptance
Period specifying the maximum number of Shares such Other Shareholder will
purchase (the "First Offer Shares"). If, upon the expiration of the Section 4(b)
Acceptance Period, the aggregate amount of First Offer Shares exceeds the amount
of Refused Shares, the Refused Shares shall be allocated among the Other
Shareholders as follows: (i) first, each Other Shareholder shall be entitled to
purchase no more than its Proportionate Percentage (as defined below) of Refused
Shares; (ii) second, if any of the Other Shareholders offered to purchase less
than its Proportionate Percentage in its acceptance notice so that Refused
Shares have not been allocated for purchase pursuant to (i) above (the
"Remaining Shares"), each Other Shareholder (an "Oversubscribed Shareholder")
which had offered to purchase a number of Refused Shares in excess of the amount
of Shares allocated for purchase to it in accordance with previous allocations
of such Refused Shares, shall be entitled to purchase an amount of Remaining
Shares equal to no more than its Proportionate Percentage (treating only
Oversubscribed Shareholders as Shareholders for these purposes) of the Remaining
Shares; and (iii) third, the process set forth in (ii) above shall be repeated
with respect to any Refused Shares not allocated for purchase until all Refused
Shares are allocated for purchase. For purposes of this Agreement,
"Proportionate Percentage" shall mean, as to each Other Shareholder, the
quotient obtained (expressed as a percentage) by dividing (A) the number of
Shares owned by such Other Shareholder on the first day of the Section 4(b)
Acceptance Period by (B) the aggregate number of Shares owned on the first day
of the Section 4(b) Acceptance Period by all Other Shareholders who exercise
their option to purchase Refused Shares.

     (c) If complete effective acceptance shall not be received pursuant to
Sections 4(a) and 4(b) above with respect to all of the Subject Shares offered
for sale pursuant to the Section 4 Offer Notice, then the Selling Shareholder
may (subject to complying with the provisions of Section 5 hereof) Sell all or
any portion of the Subject Shares so offered for sale and not so accepted, at a
price not less than the purchase price, and on terms not more favorable, in the
aggregate, to the purchaser thereof than the terms stated in the Section 4 Offer
Notice at any time within 90 days after the expiration of the Section 4(b)
Acceptance Period (the "Sale Period"); provided, however, that, if the Section 4
Offer contemplated an All or Nothing Sale and only a part of the Subject Shares
has been accepted by the Corporation (or


<PAGE>


                                      -12-


its Permitted Nominee) and the Other Shareholders following the expiration of
the Section 4(b) Acceptance Period, the Selling Shareholder may Sell all of, or
a portion of, the Subject Shares held by such Selling Shareholder. To the extent
the Selling Shareholder Sells all or any portion of the Subject Shares so
offered for sale during the Sale Period, the Selling Shareholder shall promptly
notify the Corporation, and the Corporation shall promptly notify the Other
Shareholders, as to (i) the number of Shares, if any, that the Selling
Shareholder then owns, (ii) the number of Shares that the Selling Shareholder
has sold, (iii) the terms and conditions of such Sale and (iv) the name of the
beneficial and record purchasers of any Shares sold. In the event that all of
the Shares are not sold by the Selling Shareholder during the Sale Period, the
right of the Selling Shareholder to Sell such unsold Shares shall expire and the
obligations of this Section 4 shall be reinstated; provided, however, that, in
the event that the Selling Shareholder determines, at any time during the Sale
Period, that the sale of all of the Shares on the terms set forth in the Section
4 Offer Notice is impractical, the Selling Shareholder may terminate the attempt
to Sell the Subject Shares as provided in this Section 4(c) by written notice to
all Shareholders that are a Party to this Agreement and reinstate the procedures
provided in this Section 4 without waiting for the expiration of the Sale
Period.

     (d) All Sales of Subject Shares to the Corporation (or its Permitted
Nominee) and/or the Other Shareholders subject to any one Section 4 Offer Notice
shall be consummated contemporaneously at the offices of the Corporation on the
later of (i) a mutually satisfactory business day within 15 days after the
expiration of the Section 4(b) Acceptance Period or (ii) the fifth business day
following the receipt of all regulatory approvals, if any (including, without
limitation, (A) the expiration or termination of all waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended ("HSR") and (B)
the receipt of all approvals required by any applicable Canadian regulatory
authorities), applicable to such sales, or at such other time and/or place as
the parties to such sales may agree. The delivery of certificates or other
instruments evidencing such Subject Shares duly endorsed for transfer and
accompanied by stock powers shall be made on such date against payment of the
purchase price for such Subject Shares.

     (e) The requirements of this Section 4 shall not apply to (i) any Sale of
Shares by a Shareholder pursuant to Section 3(a) hereof, (ii) any other Sale as
to which the Corporation, all of the Investors and holders of at least
two-thirds (2/3) of the outstanding Shares as of the date of such Sale waive
compliance and (iii) any sale pursuant to Sections 6, 10 or 12.4 or Sales of
Shares pursuant to the letter agreement, dated as of September 7, 1999, among
WFH, the Investors and the other parties thereto.

     SECTION 5. Tag-Along Rights. Subject to Section 5(c) and except for any
Sale of Shares pursuant to Sections 3(a)(i), 3(a)(ii), 3(a)(iv), 3(a)(v),
3(a)(vi) or 3(b)(iii), Section 10 (with respect to Sales by In-

the letter agreement, dated as of September 7, 1999, among WFH, the Investors
and the other parties thereto, or any Sale of Shares to the Corporation (or its
Permitted Nominee) and/or the Other Shareholders pursuant to Section 4, each
Shareholder shall not, whether acting alone or in concert with any Other
Shareholders, in any transaction or series of transactions, Sell any Shares to
another Person or Group (other than to an Investor), except in accordance with
the following procedures:

     (a) (i) Any Shareholder or Shareholders proposing to Sell Shares (for
purposes of this Section, the "Section 5 Seller") shall first deliver to each
Section 5 Other Shareholder (as defined below) a written notice (the "Section 5
Notice"), which shall specifically identify the proposed transferee (the
"Section 5 Purchaser"), the amount and type of Shares proposed to be sold, the
purchase price therefor, and a summary of the other material terms and
conditions of the proposed sale, and shall contain an offer (the "Section 5
Offer") by the Section 5 Purchaser to each Section 5 Other Shareholder, which
shall be irrevocable for a period of ten days after the delivery thereof (the
"Section 5 Acceptance Period") (and, to the extent the Section 5 Offer is
accepted during such ten day period, until the closing of the Sale contemplated
by the Section 5 Offer), to purchase an amount of Shares of such Section 5 Other
Shareholder (as defined below) at the same price per share (and, in the case of
Common Share Equivalents, such price per share multiplied by the number of
Common Shares issuable upon the conversion, exchange or exercise of such Common
Share Equivalent subject to reduction, if appropriate, for the amount per share
of the exercise or purchase price (if any) to be paid by the holder of such
Common Share Equivalent) to be paid to, and upon the same terms and conditions
as, the Section 5 Seller. A copy of the Section 5 Notice shall promptly be sent
to the Corporation. Notice of a Section 5 Other Shareholder's intention to
accept a Section 5 Offer, in whole or in part, shall be evidenced by a writing
signed by such Section 5 Other Shareholder and delivered to the Section 5
Purchaser as specified in the Section 5 Notice and the Corporation prior to the
end of the Section 5 Acceptance Period, setting forth the number of Shares that
such Section 5 Other Shareholder elects to Sell; provided, however, that such
Section 5 Other Shareholder may only sell up to that number of Shares
(calculated in accordance with Section 2) as shall equal the product of (x) a
fraction, the numerator of which is the number of Shares owned by the Section 5
Other Shareholder as of the date of such proposed sale and the denominator of
which is the aggregate number of outstanding Shares as of the date of such
proposed sale, multiplied by (y) the aggregate number of Shares proposed to be
sold by the Section 5 Seller. The number of Shares proposed to be sold by the
Section 5 Seller shall be reduced if and to the extent necessary to provide for
such sale of Shares by such Section 5 Other Shareholders electing to exercise
their right to Sell Shares under this Section 5. If effective acceptance by any
Section 5 Other Shareholders has been received pursuant to this paragraph (a),
then the Selling Shareholder shall not consummate such Sale of Shares without
participation of such Section 5 Other Shareholders. For purposes of this

Agreement, "Section 5 Other Shareholder" shall mean any Other Shareholder that
is an Investor or a Material Investor.

     (b) All Sales of Shares to the Section 5 Purchaser shall be consummated
contemporaneously at the offices of the Corporation on a mutually satisfactory
business day as soon as practicable, but in no event more than 15 days after the
expiration of the Section 5 Acceptance Period, or, if later, the fifth business
day following the receipt of all regulatory approvals, if any (including,
without limitation, (A) the expiration or termination of all waiting periods
under HSR and (B) the receipt of all approvals required by any Canadian
regulatory authorities), applicable to such Sales. The delivery of certificates
or other instruments evidencing such Shares duly endorsed for transfer shall be
made on such date against payment of the purchase price for such Shares.

     (c) Anything contained herein to the contrary notwithstanding, any Selling
Shareholder shall, prior to complying with the provisions of this Section 5,
shall have first complied with the provisions of Section 4 hereof.

     SECTION 6. Bring-Along Rights.

     (a) Until the earlier of (x) eighteen (18) months after the date hereof,
and (y) an IPO by the Corporation, if WFH proposes to Sell to any Person or
Group of Persons (collectively, a "Buyer"), in a bona fide arm's-length
transaction or series of transactions, including by way of a purchase agreement,
tender offer, merger or other business combination transaction or otherwise, all
of the Shares held by it at a price per Share of more than 300% of the Adjusted
Initial Per Share Price (any such transaction being referred to herein as an
"Exit Sale"), then WFH may elect to require all Other Shareholders to Sell all
Shares beneficially owned by each of them concurrently with such Exit Sale to
such Buyer at the purchase price per share (and, in the case of Common Share
Equivalents, such purchase price per share multiplied by the number of Common
Shares issuable upon the conversion, exchange or exercise of such Common Share
Equivalent subject to reduction, if appropriate, for the amount per share of the
exercise or purchase price (if any) of such Common Share Equivalent), including
any fees and the value of any other consideration received by WFH or its
Affiliates in connection with the Exit Sale, and upon the same terms and
conditions, of the Exit Sale.

     (b) The rights set forth in Section 6(a) shall be exercised by giving
written notice (the "Section 6 Notice") to each Other Shareholder setting forth
in detail the terms of the proposed Sale and the proposed closing date of the
Exit Sale, which proposed date (the "Section 6 Closing Date") shall be the later
of (i) a business day not less than 15 or more than 60 days after such Section 6
Notice is delivered to the Other Shareholders or (ii) the fifth


<PAGE>


                                      -15-


business day following the receipt of all regulatory or third party consents and
approvals, if any, applicable to such Sale.

     (c) Each Other Shareholder will (i) take all such actions, including,
without limitation, voting in favor of such proposed Sale and waiving any
appraisal, dissenter or similar rights under applicable law, as may be requested
by WFH to carry out the purposes of this Section 6, and (ii) execute all
documents reasonably requested by WFH containing such terms and conditions,
including, without limitation, representations and warranties with respect to
(x) matters of title to such Other Shareholder's securities and (y) the due
authorization (or capacity) and due and valid execution and delivery by such
Other Shareholder of documentation in respect of the Exit Sale, as those
executed by WFH; provided, however, such Other Shareholder shall not be required
to make any other representations and warranties and shall not be required to
join in any indemnity other than with respect to such Other Shareholder's
specific representations and warranties described above, or be a party to any
non-compete or similar provision.

     (d) All Sales of Shares to the Buyer pursuant to this Section 6 shall be
consummated contemporaneously at the offices of the Corporation (or such other
place as is mutually agreed upon by the parties in advance) on the Section 6
Closing Date. The delivery of certificates or other instruments evidencing the
Sale of such Shares, duly endorsed for transfer, shall be made on such date
against payment of the purchase price for such Shares. WFI will bear all of the
costs and expenses incurred solely in connection with an Exit Sale to the extent
such costs are incurred for the benefit of all Shareholders and are not
otherwise paid by the Corporation or the Buyer.

     (e) Notwithstanding anything to the contrary contained herein, any Sale of
Shares pursuant to an Exit Sale shall be exempt from the provisions of Section 4
hereof.

     SECTION 7. Preemptive Rights.

     (a) Except for Exempt Securities (as defined below), the Corporation shall
not issue, sell or exchange, or agree to issue, sell or exchange (collectively,
"Issue," and any issuance, sale or exchange resulting therefrom, an "Issuance")
(i) any of the Corporation's capital shares, (ii) any Common Share Equivalent or
(iii) any other equity security of the Corporation, including any rights to
subscribe for, purchase or otherwise acquire any capital shares or other equity
security of the Corporation (collectively, an "Equity Security") unless, in each
case, the Corporation shall have first given written notice (the "Section 7
Offer Notice") to each then holder of Preferred Shares (each a "Preemptive
Holder") which shall (a) state the Corporation's intention to sell Equity
Securities, the amount to be issued, sold or exchanged, the terms of such
securities, the purchase price therefor and a summary of the


                                      -16-


<PAGE>

other material terms of the proposed Issuance and (b) offer (a "Preemptive
Offer") to Issue to each Preemptive Holder such Preemptive Holder's Pro Rata
Share (as defined below) of such securities (with respect to each Preemptive
Holder, the "Offered Securities") upon the terms and subject to the conditions
set forth in the Section 7 Offer Notice, which Preemptive Offer by its terms
shall remain open for a period of 15 days from the date it is delivered by the
Corporation to the Preemptive Holder (and, to the extent the Preemptive Offer is
accepted during such 15 day period, until the closing of the Sales contemplated
by the Preemptive Offer). "Pro Rata Share," for purposes of this Section, shall
mean the quotient obtained by dividing (i) the number of Common Shares, as
determined in accordance with Section 2, owned by that Preemptive Holder on the
date of the Preemptive Offer, by (ii) the total number of Common Shares
outstanding, as determined by Section 2 hereof, on the date of the Preemptive
Offer.

     (b) Notice of a Preemptive Holder's intention to accept a Preemptive Offer,
in whole or in part, shall be evidenced by a writing signed by the Preemptive
Holder and delivered to the Corporation prior to the end of the 15 day period of
such Preemptive Offer (each, a "Section 7 Notice of Acceptance"), setting forth
such portion of the Offered Securities that the Preemptive Holder elects to
purchase.

     (c) (i) In the event that a Section 7 Notice of Acceptance is not given by
a Preemptive Holder accepting all of its Offered Securities, the Corporation
shall have 30 days following the earlier of (A) delivery of the Section 7 Notice
of Acceptance and (B) the expiration of the 15 day period referred to in clause
(b) above if no Section 7 Notice of Acceptance is delivered, to Issue all or any
part of such remaining Offered Securities not covered by the Section 7 Notice of
Acceptance to any other Person or Persons, but only upon terms and conditions,
including, without limitation, per Share price, payment terms and dividend
payment rates, interest rates, conversion ratios or similar terms, if any, which
are no more favorable, in the aggregate, to such other Person or Persons or less
favorable to the Corporation than those set forth in the Preemptive Offer.

     (ii) If the Corporation does not consummate the Issuance of all or part of
the remaining Offered Securities to such other Person or Persons within the 30
day period referred to in clause (c) above, the right provided hereunder shall
be deemed to be revived and such securities shall not be offered unless first
reoffered to the Preemptive Holders in accordance with this Section 7.

     (iii) The purchase by a Preemptive Holder of any Offered Securities is
subject in all cases to the execution and delivery by the Corporation and the
Preemptive Holder of a purchase agreement relating to such Offered Securities in
form and substance similar in all material respects to the extent applicable to
that executed and delivered between the Corporation and such other persons. All
Issuances of Shares to any Preemptive Holder pursuant to this Section 7 shall be
consummated contemporaneously at the offices of the Cor-

later of (A) a business day not less than 15 or more than 60 days after the end
of the 15 day period referred to in clause (b) above, and (B) the fifth business
day following the receipt of all regulatory or third party consents and
approvals, if any, applicable to such Sales, or at such other time and/or place
as the parties to such Sales may agree. The delivery of certificates or other
instruments evidencing such Shares duly endorsed for transfer shall be made on
such date against payment of the purchase price for such Shares.

     (d) As used herein, "Exempt Securities" shall mean: (i) any Common Shares
issuable or issued to employees, directors and consultants of the Corporation
pursuant to any employee benefit plans, and which issuances have been approved
in accordance with Section 9 or are Employee Shares (as defined in the Purchase
Agreement); (ii) any Series A Non-Voting Preferred Shares issued pursuant to the
Purchase Agreement and any Common Shares or Series B Voting Preferred Shares
issuable upon the conversion of any such Series A Non-Voting Preferred Shares;

holding Shares or by having persons designated by or affiliated with such
Investor serving on the Board or any Subsidiary's Board of Directors (or the
functional equivalent thereof in the case of non-corporate Subsidiaries) or
otherwise, no Investor nor any of the Investor Affiliates shall have any
obligation to the Corporation, any Subsidiary or any holder of Shares to refrain
from competing with the Corporation or any Subsidiary, making investments in
Competing Businesses, otherwise engaging in any commercial activity, and none of
the Corporation, any Subsidiary or any holder of Shares (other than such

Subsidiary, and none of the Corporation, any Subsidiary or any holder of Shares
(other than the Investor) shall have any rights or expectancy by virtue of such
Investor's relationships with the Corporation, any Subsidiary, this Agreement or
otherwise in and to such independent ventures or the income of profits derived
therefrom; and the pursuit of any such venture, even if such investment is in a
Competing Business, shall not be deemed wrongful or improper. No Investor nor
any Investor Affiliates shall be obligated to present any particular investment
opportunity to the Corporation or any Subsidiary even if such opportunity is of
a character that, if presented to the Corporation or a Subsidiary, could be
taken by the Corporation or such Subsidiary, and the Investor and their Investor
Affiliates shall continue to have the right to


                                      -22-


<PAGE>

take for their own respective account or to recommend to others any such

     (a) To the fullest extent permitted by law, from and after the date hereof
until an IPO resulting in at least $150,000,000 of gross aggregate proceeds to
the Corporation and any Selling Shareholders before deducting underwriting
discounts and commissions and offering expenses, the Corporation shall not, and
shall not permit any of its Subsidiaries to, directly or indirectly, undertake

written notice (a "Major Transaction Notice"), setting forth in detail the
proposed terms of any Major Transaction and the proposed closing date (if
applicable) of the Major Transaction and (2) within thirty (30) days of

part of the reporting entity, and (C) are described in a written notice
delivered to each of the Investors prior to implementation thereof;

     (l) the Corporation shall authorize, issue or Sell any Shares for a

     SECTION 10. Liquidity Rights.

     (a) Following the fourth anniversary of the date hereof, in the event the
Corporation has not completed a Qualified IPO, (i) any of DLJ, GSCP or
Providence, or (ii) Tyco, together with one of DLJ, GSCP or Providence (a
"Section 10 Seller"), may require the Corporation (provided the Corporation does
not exercise its right to either (i) acquire or (ii) cause a third party to
acquire, all but not less than all of the Shares held by the Section 10 Seller
and its Investor Affiliates pursuant to paragraph (b) below), to conduct,
pursuant to the auction process set forth below (the "Auction"), or otherwise as
provided in paragraph (c) below, a sale of the Corporation, whether by means of
a sale of all or substantially all of the Shares of the Corporation, a merger, a
sale of all or substantially all of the assets of the Corporation, or other
business combination transaction to a third party not affiliated with the
Investor exercising the Section 10 Offer (the "Acquiror").

     (b) A Section 10 Seller may initiate an Auction by delivering written
notice to the Corporation and each other Investor (the "Section 10 Notice"),
which shall (i) contain an offer (the "Section 10 Offer") by the Section 10
Seller to the Corporation to sell all, but not less than all, of the Shares held
by the Section 10 Seller to the Corporation or a third party identified by the
Corporation for the greater of (a) the liquidation preference of the Shares and
(b) Fair Market Value (the "Section 10 Minimum Price") during the Section 10
Option Period (as defined below) and (ii) shall set forth the Section 10 Minimum
Price, as determined in accordance with Section 1.7. Each other Investor shall
have a period of 10 days after receipt of the Section 10 Offer to notify the
Corporation in writing that it also makes a Section 10 Offer on the same terms
as the original Section 10 Offer. All Sales of Shares pursuant to the Section 10
Offers shall be consummated contemporaneously at the offices of the Corporation
on a mutually satisfactory business day as soon as practicable, but in any event
not later than 180 days after the delivery of the original Section 10 Offer (the
"Section 10 Offer Period"). The delivery of certificates or other instruments
evidencing such Shares duly endorsed for transfer shall be made on such date
against payment of the purchase price for such Shares. The Corporation or third
party purchaser shall bear all costs and expenses incurred in connection with a
Section 10 Sale. If any such purchase is not consummated in accordance with this
Section 10, including without limitation due to failure by the Corporation or
third party purchaser to pay the purchase price, such Section 10 Offer shall be
deemed to have not been accepted by the Corporation.

                                      -27-


     (c) If the Corporation or another Person shall not have purchased all of
the Section 10 Offered Shares for not less than the Section 10 Minimum Price
prior to the expiration of the Section 10 Offer Period or if the Corporation
shall have rejected the Section 10 Offer, the Corporation shall at the election
of the Section 10 Seller either (i) retain an investment bank of national
reputation (the "Auctioneer") to conduct the Auction on the Corporation's behalf
or (ii) cause the Corporation to be sold in such other manner as the Section 10
Seller may elect with the consent of a Supermajority of the Investors (which may
include the Section 10 Seller). If the Corporation is to be sold by Auction, the
Auction shall be conducted pursuant to bidding procedures that are (i)
determined by the Auctioneer in its sole discretion, and (ii) uniformly
applicable and applied to all interested parties who are identified by the
Auctioneer or are otherwise invited to participate in the Auction for the
submission and evaluation of proposals. The Auction shall be completed as
promptly as possible and in any event within six months of the expiration of the
Section 10 Offer Option Period. The Corporation shall provide the Auctioneer
with all reasonable assistance requested by the Auctioneer to consummate the
Auction. All Shareholders and each of the Investors shall have the right to
submit a bid pursuant to the Auction for the outstanding Shares of the
Corporation not held by them and have such bid evaluated on a basis no more or
less favorable than that afforded to other participants in the Auction; provided
that for so long as WFH or any Investor shall wish to have its bid considered
pursuant to the Auction, WFH or such Investor, as the case may be, and its
representatives on the Board shall be recused from all information received or
considered by the Corporation or the Board with respect to the Auction or the
Board with respect to the Auction or the results thereof. The Acquiror shall be
identified by the Auctioneer at the conclusion of the Auction; provided, that
the bid by such Acquiror shall be satisfactory to the Section 10 Seller, and the
sale of such assets or capital shares of the Corporation to such Acquiror shall
constitute the "Required Sale" unless, prior to a binding agreement for the
Required Sale being entered into with the Acquiror, the Board shall determine in
good faith, after consultation with its financial and legal advisors, that any
bona fide written proposal from a third party for a competing transaction is
more favorable to the shareholders of the Corporation from a financial point of
view than the Required Sale, is likely to and capable of being consummated, and
is in the best interest of the shareholders of the Corporation, and the
Corporation has determined that failure to enter into such a competing
transaction will constitute a breach of the Board's fiduciary duties under
applicable law.

     (d) If the Required Sale is by means of a Sale of all or substantially all
of the issued and outstanding Shares of the Corporation, then the Required Sale
shall constitute an Exit Sale for purposes of Section 6 and the provisions of
Section 6 shall be applicable to such Required Sale as if the Section 10 Seller
had all of the rights of WFH thereunder to require the Other Shareholders to
participate in such Required Sale, provided, however, that if the Required Sale
shall not be consummated, all of the provisions of this Section 10 shall then be
reinstated.


<PAGE>


                                      -28-


     (e) If the Required Sale is other than by means of a sale of the
outstanding capital shares of the Corporation, then the Corporation shall
deliver a written notice (the "Required Sale Notice") to each Shareholder
setting forth in detail the terms of the proposed Required Sale and the proposed
closing date of the Required Sale, which proposed date (the "Required Sale
Closing Date") shall be the later of (i) a Business Day not less than 15 or more
than 60 days after such Required Sale Notice is delivered to the Shareholders,
or (ii) the fifth day following the receipt of all regulatory or third party
consents and approvals, if any, applicable to such Required Sale. Each
Shareholder will (x) take all such actions, including, without limitation,
voting in favor of such proposed Sale and waiving any appraisal, dissenter or
similar rights under applicable law, as may be requested by the first initial
Section 10 Seller to carry out the purposes of this Section 10 and (y) execute
all documents reasonably requested by the initial Section 10 Seller containing
such terms and conditions, including, without limitation, representations and
warranties with respect to (x) matters of title to such Other Shareholder's
securities and (y) the due authorization (or capacity) and due and valid
execution and delivery by such Other Shareholder of documentation in respect of
the Required Sale, as those executed by the initial Section 10 Seller; provided,
however, such Other Shareholder shall not be required to make any other
representations and warranties and shall not be required to join in any
indemnity other than with respect to such Other Shareholder's specific
representations and warranties described above, or be a party to any non-compete
or similar provision. The Required Sale shall be consummated at the offices of
the Corporation on the Required Sale Closing Date. The Corporation will bear all
costs and expenses incurred in connection with the Required Sale to the extent
such costs and expenses are not otherwise paid by the Acquiror. If the Required
Sale shall not be consummated, all of the provisions of this Section 10 shall
then be reinstated.

         Shareholder's agreement, registration rights agreement, etc.) or (B)
         otherwise with or relating to the Corporation.

     SECTION 12. Certain Covenants.

     12.1. Protection of Investors. The Corporation and the Shareholders each

enforced or remedied by the Investors (severally and not jointly) and their
permitted successors and assigns.

Seller") shall have the absolute right at any time thereafter by giving written
notice to Ledcor and each other Investor (the "Put Notice"), to sell to Ledcor

not apply to a Sale of Shares pursuant to this Section 12.4.

and officers' liability insurance described in Section 6.2(k) of the Purchase
Agreement.

     12.12. Disclosure of Investment. The Corporation, on the one hand, and each
of the Investors, on the other hand, agrees that it will not use in advertising
or publicity the name of any party hereto, or any partner or employee of such
party hereto or any of its respective affiliates, or any trade name, trademark,
trade device, service mark, symbol or any abbreviation, contraction or
simulation thereof owned by the other party hereto or any of its respective
affiliates, in either case without the prior written consent of such party
(except as such release or announcement may be required by applicable securities
law or the rules or regulations of the United States Securities and Exchange
Commission, in which case the party required to make the release or announcement
shall make reasonable best efforts to allow each other party reasonable time to
comment on such release or announcement in advance of such issuance). From and
after the date hereof, neither the Corporation nor any of its Subsidiaries will
represent, directly or indirectly, that any product or any service provided by
the Corporation has been approved or endorsed by any Investor without the prior
written consent of all of


                                      -34-


<PAGE>

the Investors. The Corporation and each of the Investors further agree that,
from the date hereof through the Closing Date, no public release or announcement
concerning the transactions contemplated hereby shall be issued by any party
without the prior consent of the Corporation and each Investor (which consent
shall not be unreasonably withheld), except as such release or announcement may
be required by applicable securities law or the rules or regulations of the
United States Securities and Exchange Commission, in which case the party
required to make the release or announcement shall make reasonable best efforts
to allow each other party reasonable time to comment on such release or
announcement in advance of such issuance.

     12.13. Investor Consent for Conversion. WFH agrees that it will not convert
any Class B Subordinate Voting Shares held by WFH into Series A Non-Voting
Preferred Shares without the consent of each of the Investors.

     12.14. Restrictions on Conversions into Voting Shares. (a) Each of the
Investors agrees that it may convert any Series A Non-Voting Preferred Shares
into Series B Voting Preferred Shares or any Class A Non-Voting Shares into
Class B Subordinate Voting Shares only concurrently with or after (1) any
underwritten public offering of shares with voting rights providing gross
aggregate proceeds to the Corporation or any selling shareholders of at least
$150,000,000 before deducting underwriting discounts and commissions and
offering expenses or (2) the Corporation has issued, paid any dividend of, or
made any distribution of, any shares with voting rights other than the Class B
Subordinate Voting Shares issued and outstanding as of the Initial Issue Date
and the Class C Multiple Voting Shares issued pursuant to the Ledcor Roll-Up
Agreement. The Corporation will provide to the Investors timely information
regarding the transactions referred to in clause (1) or (2) of the preceding
sentence in order to permit the Investors timely to convert Shares in accordance
with this Section 12.14 and the terms of such Shares. Notwithstanding the
foregoing, following the elimination of the restrictions on the ownership of
voting shares and on the control in fact of the Corporation by non-Canadians
under the Telecommunications Act (Canada) and the rules and regulations
promulgated thereunder, there shall be no restrictions on the conversion by the
Investors of any Series A Non-Voting Preferred Shares into Series B Voting
Preferred Shares or any Class A Non-Voting Shares into Class B Subordinate
Voting Shares.

     (b) (i) The Corporation shall not issue any capital shares or equity

Telecommunications Act (Canada) and the Ownership Regulations (as defined below)
except Sales of Shares pursuant to the Purchase Agreement or the Ledcor Roll-Up
Agreement.

     (ii) WFH shall not sell, assign or otherwise dispose of any capital shares
or equity securities which fall within the definition of "voting shares" in the

suant to Rule 144A of the Securities Act (or an analogous provision of Canadian
Securities Laws).

     (iii) This Section 12.14(b) shall terminate following (x) the elimination
of the restrictions on the ownership of voting shares and on the control in fact
of the Corporation by non-Canadians under the Telecommunications Act (Canada)
and the Ownership Regulations promulgated thereunder or (y) any underwritten
public offering of Shares that do not fall with the definition of "voting
shares" in the Telecommunications Act (Canada) and the Ownership Regulations
providing gross aggregate proceeds to the Corporation of at least $150,000,000
before deducting underwriting discounts and commissions and offering
commissions.

     (c) To the extent required by the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, and the rules and regulations promulgated thereunder
(the "HSR Act"), if any of the Investors elect to convert their non-voting
Shares into voting Shares, such Investor and (upon written request by such
Investor) the Corporation agree to (i) file or cause to be filed, as promptly as
practicable after such request, with the United States Federal Trade Commission
and the Antitrust Division of the United States Department of Justice, all
reports and documents required to be filed by such Investors and the Corporation
under the HSR Act concerning the conversion transaction and (ii) promptly comply
with or cause to be complied with any requests by the United States Federal
Trade Commission or the Antitrust Division of the United States Department of
Justice for additional information concerning such transactions in order to
obtain antitrust regulatory clearance as soon as possible. The Company agrees to
request, and to cooperate with any Investor in requesting, early termination of
any applicable waiting period under the HSR Act.

     12.15. CEO Appointment Procedure.

     At least 10 days before the Board shall hold a meeting (the "Preliminary
CEO Appointment Meeting") to consider the appointment of a chief executive
officer (or the functional equivalent) of the Corporation ("CEO"), the
Corporation shall provide to each Investor the name of such individual and
biographical information as contemplated by Item 401 of Regulation S-K under the
Securities Act. If at, or prior to the Preliminary CEO Appointment Meeting, a
Supermajority of Investors indicate by written notice to the Corporation that
they disapprove of the appointment of the proposed CEO (a "Preliminary CEO
Disapproval"), then (i) no formal vote shall be taken on the appointment of the
proposed CEO at the Preliminary CEO Appointment Meeting and (ii) the Corporation
shall not hire the proposed CEO unless and until the Board passes a resolution
appointing the proposed CEO at a meeting of the Board (the "CEO Effective
Appointment Meeting") subsequent to the date the Preliminary CEO Appointment
Meeting is originally scheduled to be held, which meeting shall be held not
earlier than the tenth day following the date the Preliminary CEO Appointment
Meeting is


<PAGE>


                                      -36-


originally scheduled to be held. If there is not a Preliminary CEO Disapproval,
then this Section 12.15 shall have no further application with respect to the
proposed CEO (but shall be applicable to any other individual proposed as CEO).
If, within the 15 day period commencing on the first day immediately following
the date the Preliminary CEO Appointment Meeting is originally scheduled to be
held, either (i) a CEO Effective Appointment Meeting does not occur, or (ii) the
Corporation does not hire the proposed CEO, then the Corporation may not hire
such proposed CEO or any other proposed CEO except with renewed compliance with
all of the terms of this Section 12.15. The provisions of this Section 12.15
shall terminate upon an IPO resulting in at least $150,000,000 of gross
aggregate proceeds to the Corporation before deducting underwriting discounts
and commissions and offering expenses.

     12.16. Ledcor Entities Regulatory Covenants.

     (a) Ledcor represents and warrants, and agrees that during the period prior
to the completion of the transaction contemplated by the Ledcor Roll-Up
Agreement, Ledcor shall, and shall cause Ledcor Industries Limited to ensure
that:

                 (i) no Ledcor Entity is in violation of any judgment, decree,
         order, writ, law, statute, rule, directive or regulation rendered or
         enacted in Canada or any non-Canadian jurisdiction respecting
         telecommunications and the regulation within Canada of
         "telecommunications common carriers" (as defined in the
         Telecommunications Act) or in any non-Canadian jurisdiction respecting
         telecommunications applicable to any of the Ledcor Entities, or, to the
         knowledge of Ledcor, any published interpretation or policy relating
         thereto applicable to any Ledcor Entity. Except as disclosed in
         Schedule 12.16(a)(i), no notices, reports or other filings are required
         to be made by any Ledcor Entity during the period prior to the
         completion of the transaction contemplated by the Ledcor Roll-Up
         Agreement, with, nor are any consents, registrations, applications and
         Permits required to be obtained by any Ledcor Entity from, any court or
         governmental agency or other regulatory body or tribunal or similar
         entity pursuant to Canadian or non-Canadian telecommunications and
         radiocommunication regulatory law in connection with the completion of
         the transaction contemplated by the Ledcor Roll-Up Agreement. The
         development, implementation, construction or operation of the
         telecommunications assets of Ledcor Industries Limited does not
         conflict with and will not result in a breach or violation of any of
         the Communications Statutes (as defined below) or existing regulations
         thereunder except breaches or violations which may be remedied by
         Ledcor at immaterial expense and which would not otherwise have a
         Material Adverse Effect on the WFI Entities taken as a whole or Ledcor.
         For the purposes of this Agreement, "Communications Statutes" means the
         Telecommunications Act, the Canadian Radio-television and
         Telecommunications Commission Act, or other statutes of Canada or any
         non-Canadian jurisdiction specifically relating to the regulation of
         the telecommunications industry within Canada or any non-Canadian
         jurisdiction (including for this purpose the orders, rules,
         regulations, directives, decisions, notices and policies promulgated
         pursuant to such statutes, and applicable statutes or regulations, if
         any, of any province of Canada or State of the U.S. specifically
         relating to the


<PAGE>


                                      -37-


         regulation of the Canadian or U.S. telecommunications industry and the
         orders, rules, regulations, directives, decisions, notices and policies
         promulgated thereunder);.

                (ii) (A) Ledcor Industries Limited will remain eligible to
         operate as a telecommunications common carrier in Canada, as defined
         under and in accordance with the Telecommunications Act and the
         Canadian Telecommunications Common Carrier Ownership and Control
         Regulations (the "Ownership Regulations"); (B) Ledcor Industries
         Limited will not violate the prohibition contained in subsection 16(4)
         of the Telecommunications Act against operating in Canada as a
         telecommunications common carrier when ineligible to do so; and (C)
         control of Ledcor Industries Limited will not be 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
         term "Canadian" under the Ownership Regulations; and

               (iii) (A) not less than eighty percent of the members of the
         board of directors of Ledcor Industries Limited will continue to be
         individual Canadians, as defined under the Ownership Regulations; (B)
         Canadians, as defined under the Ownership Regulations, will continue to
         beneficially own directly or indirectly, in the aggregate and otherwise
         than by way of security only, not less than eighty percent of the
         issued and outstanding voting shares, as defined under the Ownership
         Regulations, of Ledcor Industries Limited; (C) Ledcor in respect of its
         ownership of and control over Ledcor Industries Limited will remain a
         carrier holding corporation, as defined under the Ownership
         Regulations; (D) Ledcor will continue to be a carrier holding
         corporation that is a qualified corporation, as defined under the
         Ownership Regulations; and (E) Ledcor Industries Limited will not be
         controlled in fact by non-Canadians.

     (b) With the exception of Ledcor Industries Limited and Worldwide Fiber
(F.O.T.S.) Ltd., no other subsidiary of Ledcor operates in Canada as a
telecommunications common carrier as that term is defined in the
Telecommunications Act.

     (c) During the period prior to the completion of the transaction
contemplated by the Ledcor Roll-Up Agreement, all Ledcor Entities will remain in
compliance with all federal, state and local telecommunications laws, rules,
regulations and policies in the United States to which they are subject,
including the Communications Act of 1934, as amended by the Telecommunications
Act of 1996 (the "Communications Act") or to any

<PAGE>


                                      -38-


rules, regulations and policies of the FCC related hereto, except where failure
to comply would not have a Material Adverse Effect on the WFI Entities taken as
a whole or Ledcor.

     (d) Except as set forth in Schedule 12.16(d), each of the Ledcor Entities
currently holds all licenses, permits, certificates, waivers, consents,
franchises, orders, approvals and authorizations issuable under the
Telecommunications Act or other similar Canadian or U.S. statutes which are
required for the development, implementation and operation of each Ledcor Entity
business as it is currently being conducted (collectively, the
"Telecommunications Licenses"). Each Ledcor Entity is in material compliance
with each Telecommunications License held by it. The Telecommunications Licenses
held by each Ledcor Entity contain no restrictions or conditions attaching to
the Telecommunications Licenses, that are (or would be) materially burdensome to
the Ledcor Entities and there are no other conditions attaching to the
Telecommunications Licenses.

     (e) Except as set forth in Schedule 12.16(e), each of the Ledcor Entities
has timely filed all renewal applications with respect to all Telecommunications
Licenses held by any of them and no protests or competing applications have been
filed that are either available to the Ledcor Entities or of which the Ledcor
Entities have knowledge with respect to such renewal applications and nothing
has come to the attention of any of the Ledcor Entities that would lead them to
conclude that such renewal applications will not be granted by the appropriate
regulatory agency or body in the ordinary course, and the Ledcor Entities are
authorized under the Communications Statutes and the rules and regulations
promulgated thereunder to continue to provide the services which are the subject
of such renewal applications during the pendency thereof.

     (f) The telecommunications business of the Ledcor Entities is not regulated
by any federal, state or provincial utility or rate-regulating commission, other
than the CRTC and Industry Canada, in the areas in which any Ledcor Entity
conducts or proposes to conduct such business, and the Ledcor Entities are not,
and based on existing regulations will not be, required to obtain any
Telecommunications License from any such utility or rate-regulating commission,
other than the CRTC and Industry Canada, in any such state or province.

     (g) Ledcor shall cause Ledcor Industries Limited to take all necessary
actions by December 31, 1999 to, as soon as possible, assign and transfer
(including obtaining the approval of Industry Canada to such assignment) to the
Corporation or a wholly-owned Subsidiary of the Corporation all right, title and
interest of Ledcor Industries Limited in, to and under the International
Submarine Cable License issued by Industry Canada to Ledcor Industries Limited
and 3477967 Canada Inc. effective November 1, 1998 (the "ISCL License") pursuant
to the International Submarine Cable Licenses Regulations, in respect of a fiber
optic international submarine cable between the cable stations at Cordova Bay,
British Columbia and Point Roberts, Washington, and between the cable stations
located at Fleming


<PAGE>


                                      -39-


Bay, British Columbia and Whidbey Island, Washington, as more fully described in
the annexes to the ISCL License.

     12.17. Underwritten Offering-Related Lock-Up of Shares.

     If requested in writing by the managing underwriter(s), if any, of the
first IPO by the Corporation of equity securities (or securities convertible
into or exchangeable for equity securities) of the Corporation, each Shareholder
holding Shares agrees not to effect any Sale or distribution, including, without
limitation, any sale pursuant to Canadian Securities Laws or Rule 144 under the
U.S. Securities Act, of Shares (other than as part of such underwritten public
offering) during the time period requested by the managing underwriter(s), if
any, not to exceed 180 days. This Section 12.17 does not apply to any subsequent
IPO.

     SECTION 13. [Intentionally omitted]

     SECTION 14. Reservation of Common Shares; Conversion.

     (a) The Corporation shall at all times reserve and keep available out of
its authorized but unissued capital (i) sufficient Common Shares to permit
conversion of all outstanding Series A Non-Voting Preferred Shares and any
outstanding Series B Voting Preferred Shares and (ii) sufficient Preferred
Shares to satisfy the Corporation's obligation to issue additional Series A
Non-Voting Preferred Shares to the Investors in accordance with the terms of the
Purchase Agreement and to permit the conversion of the Series A Non-Voting
Preferred Shares into Series B Voting Preferred Shares. The Corporation
represents, warrants and agrees that all Common Shares and Preferred Shares
which are so issuable shall, when issued, be duly and validly issued, fully paid
and nonassessable and free from all taxes, liens, encumbrances and charges.
Ledcor, WFH and the Corporation shall take all such actions as may be necessary,
including adoption of amendments to the Articles of Continuance, to assure that
all such Common Shares may be so issued without violation of any applicable law
or governmental regulation or the Articles of Continuance of the Corporation or
any requirements of any securities exchange upon which such Common Shares may be
listed (except for official notice of issuance which shall be immediately
transmitted by the Corporation upon issuance).

     (b) The Corporation agrees that, upon the request of any of the Investors,
it will convert any Non-Voting Shares held by such Investor into Voting Shares
of the same class unless in the reasonable opinion of the Corporation such
conversion would violate the statutory restrictions on "control" as defined in
the Telecommunications Act by "non-Canadians".

                                      -40-


     SECTION 15. Confidentiality.

     (a) The Investors and each of the other Shareholders severally (the
"Confidants") recognize that certain non-public, confidential, proprietary
information ("Confidential Information") may be furnished orally or in writing
to the Confidants by, or at the direction of, the Corporation. The Confidants
agree not to disclose any Confidential Information to any Person except to a
Person who is advised of the Confidant's obligations under this Section 15 and
who is (i) a partner, managing director, director, officer or employee of a
Confidant or a Confidant's Affiliate who is involved in the Confidant's
investment in the Corporation, who is consulted with respect to such investment,
or who a Confidant determines otherwise needs to know such information, or (ii)
a Person acting as an advisor to a Confidant in connection with such investment,
except with the consent of the Corporation or pursuant to a subpoena, civil
investigative demand (or similar process), order, statute, rule or other legal
requirement promulgated or imposed by a court or by a judicial, regulatory,
self-regulatory or legislative body, organization, agency or committee or
otherwise in connection with any judicial or administrative proceeding
(including, in response to oral questions, interrogatories or requests for
information or documents) in which a Confidant or Investor Affiliate is
involved. The Confidants acknowledge that the United States securities laws
prohibit any person who is in possession of material, non-public information
regarding an issuer from purchasing or selling securities of such issuer or from
communicating such information to any other person under circumstances in which
it is reasonably foreseeable that such person is likely to purchase or sell such
securities.

     (b) If Confidential Information is to be disclosed pursuant to the
foregoing paragraph, the Confidant will, to the extent practicable, promptly
notify the Corporation thereof and cooperate with the Corporation to the extent
legally permissible if it should seek to obtain an order or other reliable
assurance that confidential treatment will be accorded to designated portions of
the Confidential Information. The Confidants shall be entitled to periodic
reimbursement from the Corporation for expenses incurred by it or any Investor
Affiliate, including the fees and expenses of counsel, in connection with any
action taken pursuant to this paragraph.

     (c) Information will not be deemed Confidential Information if it (i) was
already available to, or in the possession of, the Confidant prior to its
disclosure by, or at the direction of, the Corporation, (ii) is or becomes
available in the public domain on or after the date hereof (other than as a
result of a disclosure by any Confidant or any of its advisors), or (iii) is
acquired from a person who is not known by a Confidant to be in breach of an
obligation of confidentiality to the Corporation.

     SECTION 16. Specific Performance; Injunction.

     (a) The parties agree that it is impossible to determine the monetary
damages which would accrue to the Corporation or any Shareholder or his personal
representative by reason of the failure of any Other Shareholder or the
Corporation to perform any of his or its obligations under this Agreement
requiring the performance of an act other than the payment of money only. Each
Shareholder shall be entitled to enforce its rights under this Agreement
specifically and to exercise all other rights existing in their favor. The
parties hereto agree and acknowledge that money damages may not be an adequate
remedy for any breach of the provisions of this Agreement and that each party
may in its sole discretion apply to any court of law or equity of competent
jurisdiction for specific performance and/or injunctive relief (without posting
a bond or other security) in order to enforce or prevent any violation of the
provisions of this Agreement.

     (b) In the event of a breach or threatened breach by a Shareholder of any
of the provisions of this Agreement, the Corporation, and the remaining
Shareholders shall be entitled to an injunction restraining such Shareholder
from any such breach. The availability of these remedies shall not prohibit the
Corporation from pursuing any other remedies for such breach or threatened
breach, including the recovery of damages from the Shareholder.

     SECTION 17. No Inconsistent AgreementsNeither the Corporation nor any
Shareholder shall take any action or enter into any agreement which is
inconsistent with the rights of any party hereunder or otherwise conflicts with
the provisions hereof.

     SECTION 18. Further Assurances.

     (a) At any time or from time to time after the date hereof, the parties
agree to cooperate with each other, and at the request of any other party, to
execute and deliver any further instruments or documents and to take all such
further action as the other party may reasonably request in order to evidence or
effectuate the consummation of the transactions contemplated hereby and to
otherwise carry out the intent of the parties hereunder.

     (b) At any time or from time to time, the parties agree to take all action,
including, without limitation, voting to approve any amendment to the Articles
of Continuance, or the By-Laws of the Corporation required to increase the
authorized number of Common Shares or Preferred Shares, if necessary, to permit
the issuance of all Shares contemplated under the Purchase Agreement, and the
conversion of all outstanding Series A Non-Voting Preferred Shares or
outstanding Series B Voting Preferred Shares.

                                      -42-



     SECTION 19. Duration of Agreement. The rights and obligations of a
Shareholder under this Agreement shall terminate at such time as such
Shareholder no longer holds any Shares. This Agreement shall terminate upon the
consummation of a Qualified IPO except that the terms of Section 8, Sections
12.1, 12.3, 12.4, 12.7, 12.8, 12.9, 12.10, 12.11, 12.12, 12.13, 12.14, 12.15,
12.16, 12.17, Sections 14 through Section 32 (inclusive) shall survive until, by
their respective terms, they are no longer operative. The terms of Sections 12.5
and 12.6 shall terminate upon the consummation of an IPO.

     SECTION 20. Legends. Each certificate representing Shares shall bear a
legend containing the following words:

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         QUALIFIED FOR PUBLIC DISTRIBUTION IN CANADA AND HAVE NOT BEEN
         REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED.
         THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD,
         TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH
         APPLICABLE CANADIAN SECURITIES LAWS AND THE UNITED STATES SECURITIES
         ACT OF 1933, AS AMENDED.

                  IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE
         ARE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE
         SHAREHOLDERS AGREEMENT, DATED AS OF SEPTEMBER 9, 1999, BY THE
         CORPORATION AND THE PARTIES THERETO, A COPY OF WHICH IS ON FILE IN THE
         OFFICE OF THE CORPORATION.

     The requirement that the above securities legend be placed upon
certificates evidencing any such securities shall cease and terminate upon the
earliest of the following events: (i) when such Shares are transferred in an
IPO; (ii) when such Shares are transferred pursuant to Rule 144 under the
Securities Act; or (iii) when such Shares are transferred in any other
transaction if the seller delivers to the Corporation an opinion of its counsel,
which counsel and opinion shall be reasonably satisfactory to the Corporation to
the effect that such legend is no longer necessary in order to protect the
Corporation against a violation by it of the Securities Laws upon any sale or
other disposition of such Shares without registration thereunder. The
requirement that the above legend regarding the Shareholder Agreement be placed
upon certificates evidencing any such securities shall cease and terminate upon
the termination of this Agreement. Upon the occurrence of any event requiring
the removal of a legend hereunder, the Corporation, upon the surrender of
certificates containing such legend, shall, at its own expense, deliver to the
holder of any such Shares as to which the requirement


<PAGE>


                                      -43-


for such legend shall have terminated, one or more new certificates evidencing
such Shares not bearing such legend.

     SECTION 21. Contractual Management Rights. The Corporation and each of the
Shareholders acknowledge that the provisions of this Agreement are intended,
among other things, to provide DLJ, GSCP and Providence with "contractual
management rights" within the meaning of the Employee Retirement Income Security
Act of 1974, as amended, and the regulations promulgated thereunder.

     SECTION 22. Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid, but
if any provision of this Agreement is held to be invalid or unenforceable in any
respect, such invalidity or unenforceability shall not render invalid or
unenforceable any other provision of this Agreement. In the event that pursuant
to any regulatory authority or regulation, the Corporation is required to make
any revisions or modifications to any provision of this Agreement or any of the
other Documents, the parties agree to enter into good faith negotiations and
make revisions or modifications, to the extent possible, that are in compliance
with such regulation or the rules of such regulatory authority, and which are
designed to accomplish the purposes of such provision to be revised or modified.

     SECTION 23. Governing Law; Waiver of Jury Trial. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
without giving effect to the principles of conflicts of law, except for the
provisions of Section 8 and the provision in the last sentence of Section 10(c)
permitting a Board determination regarding a competing transaction to a Required
Sale, which shall be governed by and construed in accordance with the laws of
the Province of British Columbia and the federal law of Canada. Each of the
parties hereto hereby irrevocably and unconditionally consents to submit to the
exclusive jurisdiction of the courts of the State of New York and of the United
States of America, in each case located in the County of New York, for any
action, proceeding or investigation in any court or before any governmental
authority ("Litigation") arising out of or relating to this Agreement and the
transactions contemplated hereby (and agrees not to commence any Litigation
relating thereto except in such courts), and further agrees that service of any
process, summons, notice or document by facsimile or registered mail to its
respective address set forth in this Agreement shall be effective service of
process for any Litigation brought against it in any such court. Each of the
parties hereto hereby irrevocably and unconditionally waives any objection to
the laying of venue of any Litigation arising out of this Agreement or the
transactions contemplated hereby in the courts of the State of New York and of
the United States of America, in each case located in the County of New York,

time after the earlier of occur of (i) September 7, 2001, and (ii) the closing

Laws covering all or part of their respective Registrable Securities, by
delivering a written request therefor to the Corporation specifying the number
of Registrable Securities to be included in such registration by such holders of
Preferred Shares and the intended method of distribution thereof. All requests
pursuant to this Section 2.1 are referred to herein as "Demand Registration
Requests," and the registrations requested are referred to herein as "Demand
Registrations." With respect to any Demand Registration, the holders of a
majority of the Preferred Shares making such demand for registration shall be
referred to as the "Initiating Holders." As promptly as practicable, but no
later than ten days after receipt of a Demand Registration Request, the
Corporation shall give written notice (the "Demand Exercise Notice") of such
Demand Registration Request to all Holders of record of Registrable Securities.

     (b) The Corporation, subject to Sections 2.3 and 2.7, shall include in a
Demand Registration (i) the number of Registrable Securities requested by the
Initiating Holders of the Common Shares into which the Preferred Shares have
been or may be converted from time to time (either directly or indirectly as
Common Share Equivalents) and not been registered pursuant to a Canadian
Prospectus, a registration statement, or sold pursuant to Rule 144 under the
U.S. Securities Act and (ii) the Registrable Securities of any other Holder who
shall have made a written request to the Corporation for inclusion in such
Demand Registration (which request shall specify the maximum number of
Registrable Securities intended to be disposed of by such Holder) within 30 days
after the receipt of the Demand Exercise Notice.

     (c) The Corporation shall, as expeditiously as possible following a Demand
Registration Request, use its best efforts to (i) effect such registration under
the Securities Laws of the Registrable Securities which the Corporation has been
so requested to register, for distribution in accordance with such intended
method of distribution and (ii) if requested by the Initiating Holders, obtain
acceleration of the effective date of the registration statement relating to
such registration.

                                      -5-


     (d) The Demand Registration rights granted under Section 2.1 are subject to
the following limitations: (i) the Corporation shall not be required to cause a
registration pursuant to Section 2.1 to be declared effective within a period of
180 days after the effective date of any registration statement of the
Corporation filed pursuant to a Demand Registration Request; (ii) if the Board,
in its good faith judgment, determines that any registration of Registrable
Securities should not be made or continued because it would materially interfere
with any material financing, acquisition, corporate reorganization or merger or
other transaction involving the Corporation (a "Valid Business Reason"), (A) the
Corporation may postpone filing a registration statement relating to a Demand
Registration Request until such Valid Business Reason no longer exists, but in
no event for more than 120 days, and (B) in case a registration statement has
been filed relating to a Demand Registration Request, if the Valid Business
Reason has not resulted from actions taken by the Corporation, the Corporation
may cause such registration statement to be withdrawn and its effectiveness
terminated or may postpone amending or supplementing such registration statement
until such Valid Business Reason no longer exists, but in no event for more than
120 days (such period of postponement or withdrawal under subclauses (A) or (B)
of this paragraph (d), (the "Postponement Period"); and the Corporation shall
give written notice of its determination to postpone or withdraw a registration
statement and of the fact that the Valid Business Reason for such postponement,
withdrawal or premature termination no longer exists, in each case, promptly
after the occurrence thereof; provided, however, that the Corporation shall not
be permitted to postpone, withdraw or prematurely terminate a registration
statement after the expiration of any Postponement Period until six months after
the expiration of such Postponement Period; and (iii) the Corporation shall not
be required to effect a registration pursuant to this Section 2.1 with respect
to more than two Demand Registration Requests by each Investor under this
Agreement.

     If the Corporation shall give any notice of postponement or withdrawal of
any registration statement, the Corporation shall not, during the Postponement
Period or withdrawal, register any Common Shares, other than pursuant to a
registration statement on Form S-4 or S-8 (or an equivalent registration form
then in effect) under the U.S. Securities Act. Each Holder of Registrable
Securities agrees that, upon receipt of any notice from the Corporation that the
Corporation has determined to withdraw any registration statement pursuant to
clause (ii) above, such party will discontinue its disposition of Registrable
Securities pursuant to such registration statement and, if so directed by the
Corporation, will deliver to the Corporation (at the Corporation's expense) all
copies, other than permanent file copies, then in such party's possession, of
the prospectus covering such Registrable Securities that was in effect at the
time of receipt of such notice. If the Corporation shall have withdrawn or
prematurely terminated a registration statement filed under Section 2.1 (whether
pursuant to this paragraph (d) or as a result of any stop order, injunction or
other order or requirement of the Commission or any other governmental agency or
court), the Corporation shall not be considered to have effected an effective
registration for the purposes of this Agreement until the


<PAGE>


                                      -6-


Corporation shall have filed a new registration statement covering the
Registrable Securities covered by the withdrawn or prematurely terminated
registration statement and such subsequent registration statement shall have
been declared effective and shall not have been withdrawn or prematurely
terminated. If the Corporation shall give any notice of withdrawal or
postponement of a registration statement, the Corporation shall, at such time as
the Valid Business Reason that caused such withdrawal or postponement no longer
exists (but in no event later than 120 days after the date of the withdrawal or
postponement), use its best efforts to effect the registration under the
Securities Laws of the Registrable Securities covered by the withdrawn or
postponed registration statement in accordance with this Section 2.1 (unless the
Initiating Holders shall have withdrawn such request, in which case the
Corporation shall not be considered to have effected an effective registration
for the purposes of this Agreement).

     (e) The Corporation, subject to Sections 2.3 and 2.7, may elect to include
in any registration statement and offering made pursuant to Section 2.1, (i)
authorized but unissued Common Shares or Common Shares held by the Corporation
as treasury shares and (ii) any other Common Shares which are requested to be
included in such registration (x) pursuant to the exercise of piggyback
registration rights granted by the Corporation after the date hereof in
accordance with the terms of this Agreement and the Shareholders Agreement, (y)
by Canadian National Railway Company ("CN") pursuant to the unanimous
shareholder agreement made as of May 28, 1999 between Worldwide Fiber Networks
Ltd., CN and WFI-CN Fiber Inc., or (z) by IC Fiber Holdings Inc. ("IC") pursuant
to the limited liability company agreement of Worldwide Fiber IC LLC effective
as of May 28, 1999, between Worldwide Fiber IC Holdings, Inc. and IC
(collectively, "Additional Piggyback Rights"); provided, however, that such
inclusion shall be permitted only to the extent that it is pursuant to, and
subject to, the terms of the underwriting agreement or arrangements entered into
by the Initiating Holders.

     2.2. Piggyback Registrations.

     (a) If at any time, the Corporation proposes or is required to register any
of its equity securities under the Securities Laws (other than equity securities
registered pursuant to registrations on Form S-4 or S-8 (or an equivalent
registration form for a domestic or foreign issuer then in effect) solely for
registration of securities in connection with an employee benefit plan or
dividend reinvestment plan or a merger or consolidation or a Demand Registration
under Section 2.1 of this Agreement), whether or not for its own account, the
Corporation shall give prompt written notice of its intention to do so to each
of the Holders of record of Registrable Securities. Upon the written request of
any Holder, made within 20 days following the receipt of any such written notice
(which request shall specify the maximum number of Registrable Securities
intended to be disposed of by such Holder and the intended method of
distribution thereof), the Corporation shall, subject to Sections 2.2(b), 2.3
and 2.7, use its best efforts to cause all such Registrable Securities, the
Holders of which have so requested

<PAGE>


                                      -7-


the registration thereof, to be registered under the Securities Laws (with the
securities which the Corporation at the time proposes to register) to permit the
sale or other disposition by the Holders (in accordance with the intended method
of distribution thereof) of the Registrable Securities to be so registered. No
registration effected under this Section 2.2(a) shall relieve the Corporation of
its obligations to effect Demand Registrations under Section 2.1.

     (b) If at any time after giving written notice of its intention to register
any equity securities and prior to the effective date of the registration
statement filed in connection with such registration, the Corporation shall
determine for any reason not to register or to delay registration of such equity
securities, the Corporation may, at its election, give written notice of such
determination to all Holders of Registrable Securities, and (i) in the case of a
determination not to register, shall be relieved of its obligation to register
any Registrable Securities in connection with such abandoned registration,
without prejudice, however, to the rights of Holders of Registrable Securities
under Section 2.1 and (ii) in the case of a determination to delay such
registration of its equity securities, shall be permitted to delay the
registration of such Registrable Securities for the same period as the delay in
registering such other equity securities.

     (c) Any Holder shall have the right to withdraw its request for inclusion
of its Registrable Securities in any registration statement pursuant to this
Section 2.2 by giving written notice to the Corporation of its request to
withdraw; provided, however, that (i) such request must be made in writing prior
to the execution of the underwriting agreement (or such other similar agreement)
with respect to such registration and (ii) such withdrawal shall be irrevocable
and, after making such withdrawal, a Holder shall no longer have any right to
include Registrable Securities in the registration as to which such withdrawal
was made.

     2.3. Allocation of Securities Included in Registration Statement.

     (a) If any requested registration pursuant to Section 2.1 involves an
underwritten offering and if the lead managing underwriter (the "Manager") shall
advise the Corporation that, in its view, the number of securities requested to
be included in such registration (including those securities requested by the
Corporation to be included in such registration) exceeds the largest number (the
"Section 2.1 Sale Number") that can be sold in an orderly manner in such
offering within a price range acceptable to the Initiating Holders, the
Corporation shall include in such registration:

                  (i) first, all Registrable Securities requested to be included
         pursuant to Section 2.1(b)(i) and Section 2.2(a) in such registration
         by the beneficial owners of the Common Shares into which the Preferred
         Shares have been or may be converted from time to time (either directly
         or indirectly as Common Share Equivalents) and have not been registered
         pursuant to a Canadian Prospectus, a registration statement, or sold

<PAGE>


                                      -8-


         pursuant to Rule 144 under the U.S. Securities Act; provided, however,
         that if the number of such Registrable Securities exceeds the Section
         2.1 Sale Number, then the number of Registrable Securities (not to
         exceed the Section 2.1 Sale Number) to be included in such registration
         shall be reduced on a pro rata basis among all such holders, based on
         the number of Registrable Securities owned by each such holder
         requesting inclusion pursuant to Section 2.1(b)(i) and Section 2.2(a)
         out of the total outstanding Common Shares of the Corporation;
         provided, however, that such allocation shall not operate to reduce the
         aggregate number of Registrable Securities to be included in such
         registration, and if any Holder or other selling stockholder does not
         request inclusion of the maximum number of shares of Registrable
         Securities allocated to such Holder pursuant to the above-described
         procedure, the remaining portion of such Holder's allocation shall be
         reallocated among those requesting Holders and other selling
         stockholders whose allocations did not satisfy their requests pro rata
         on the basis of the number of shares of Registrable Securities which
         would be held by such Holders and other selling stockholders, assuming
         conversion, and this procedure shall be repeated until all of the
         shares of Registrable Securities which may be included in the
         registration on behalf of the Holders and other selling stockholders
         have been so allocated;

                  (ii) second, to the extent that the number of Registrable
         Securities to be included pursuant to Section 2.3(a)(i) is less than
         the Section 2.1 Sale Number, securities that the Corporation proposes
         to register; and

                  (iii) third, to the extent that the number of Registrable
         Securities to be included by all Holders pursuant to Section 2.3(a)(i)
         and the number of securities to be included by the Corporation pursuant
         to Section 2.3(a)(ii) is less than the Section 2.1 Sale Number, any
         other securities that the Holders thereof propose to register pursuant
         to the exercise of Additional Piggyback Rights.

     If, as a result of the proration provisions of this Section 2.3(a), any
Holder shall not be entitled to include all Registrable Securities in a
registration that such Holder has requested be included, such Holder may elect
to withdraw his request to include Registrable Securities in such registration
or may reduce the number requested to be included; provided, however, that (A)
such request must be made in writing prior to the execution of the underwriting
agreement with respect to such registration and (B) such withdrawal shall be
irrevocable and, after making such withdrawal, a Holder shall no longer have any
right to include such Registrable Securities in the registration as to which
such withdrawal was made.

     (b) If any registration pursuant to Section 2.2 where the Corporation
initiated the registration involves an underwritten offering and the Manager
shall advise the Corporation that, in its view, the number of securities
requested to be included in such registration exceeds the number (the "Section
2.2 Sale Number") that can be sold in an orderly manner in


<PAGE>


                                      -9-


such registration within a price range acceptable to the Corporation, the
Corporation shall include in such registration:

                  (i) first, all Common Shares that the Corporation proposes to
         register for its own account ("Corporation Securities");

                  (ii) second, to the extent that the number of Corporation
         Securities is less than the Section 2.2 Sale Number, all Registrable
         Securities requested to be included by any Investors and Investor
         Affiliates pursuant to Section 2.2(a) ("Investor Securities");
         provided, however, that, if the number of such Investor Securities
         exceeds the Section 2.2 Sale Number less the number of Corporation
         Securities, then the number of Investor Securities included in such
         registration shall be reduced on a pro rata basis, based on the number
         of Registrable Securities owned by each Investor requesting inclusion
         in such registration out of the number of Registrable Securities owned
         by all Investors requesting inclusion; provided, however, that such
         allocation shall not operate to reduce the aggregate number of
         Registrable Securities to be included in such registration, and if any
         Holder or other selling stockholder does not request inclusion of the
         maximum number of shares of Registrable Securities allocated to such
         Holder pursuant to the above-described procedure, the remaining portion
         of such Holder's allocation shall be reallocated among those requesting
         Holders and other selling stockholders whose allocations did not
         satisfy their requests pro rata on the basis of the number of shares of
         Registrable Securities which would be held by such Holders and other
         selling stockholders, assuming conversion, and this procedure shall be
         repeated until all of the shares of Registrable Securities which may be
         included in the registration on behalf of the Holders and other selling
         stockholders have been so allocated; and

                  (iii) third, to the extent the number of Corporation
         Securities and Investor Securities is less than the Section 2.2 Sale
         Number, all Registrable Securities requested to be included by all
         other Holders; provided, however, if the number of such Registrable
         Securities exceeds the Section 2.2 Sale Number less the number of (A)
         Corporation Securities and (B) Investor Securities, then the number of
         Registrable Securities included in such registration shall be reduced
         on a pro rata basis, based on the number of Registrable Securities
         owned by each Holder (but not Holders who are Investors or Investor
         Affiliates) requesting inclusion to the number of Registrable
         Securities owned by all Holders (but not Holders who are Investors or
         Investor Affiliates) requesting inclusion; provided, however, that such
         allocation shall not operate to reduce the aggregate number of
         Registrable Securities to be included in such registration, and if any
         Holder or other selling stockholder does not request inclusion of the
         maximum number of shares of Registrable Securities allocated to such
         Holder pursuant to the above-described procedure, the remaining portion
         of such Holder's alloca-


<PAGE>


                                      -10-


         tion shall be reallocated among those requesting Holders and other
         selling stockholders whose allocations did not satisfy their requests
         pro rata on the basis of the number of shares of Registrable Securities
         which would be held by such Holders and other selling stockholders,
         assuming conversion, and this procedure shall be repeated until all of
         the shares of Registrable Securities which may be included in the
         registration on behalf of the Holders and other selling stockholders
         have been so allocated.

     2.4. Registration Procedures. If and whenever the Corporation is required
by the provisions of this Agreement to use its best efforts to effect or cause
the registration of any Registrable Securities under the U.S. Securities Act or
Canadian Securities Laws as provided in this Agreement, the Corporation shall,
as expeditiously as reasonably possible (but in any event, within 120 days after
a Demand Registration Request in the case of Section 2.4(a)):

     (a) prepare and file with the Commission or Canadian securities regulatory
authorities a registration statement on an appropriate registration form of the
Commission or Canadian securities regulatory authorities for the disposition of
such Registrable Securities in accordance with the intended method of
disposition thereof, which form shall, in the case of a shelf registration, be
available for the sale of the Registrable Securities by the Holders thereof and
such registration statement shall comply in all material respects with the
requirements of the applicable form and include all financial statements
required by the Commission or Canadian securities regulatory authorities to be
filed therewith, and the Corporation shall use its best efforts to cause such
registration statement to become and, subject to 2.4(b), remain effective
(provided, however, that before filing a registration statement or prospectus or
any amendments or supplements thereto, or comparable statements under securities
or "blue sky" laws of any United States jurisdiction, the Corporation will
furnish to counsel (in the case of a registration pursuant to Section 2.1,
selected by the Initiating Holders, and, in the case of a registration pursuant
to Section 2.2, the Holder that, together with its Affiliates, includes the
largest number of Registrable Securities in such registration (the "Major
Holder")) for the Holders of Registrable Securities participating in the planned
offering and the underwriters, if any, copies of all such documents proposed to
be filed (including all exhibits thereto), which documents will be subject to
the reasonable review and reasonable comment of such counsel, and the
Corporation shall not file any registration statement or amendment thereto or
any prospectus or supplement thereto to which the Initiating Holder, in the case
of a Demand Registration Request, or the underwriters, if any, shall reasonably
object in writing);

     (b) prepare and file with the Commission or Canadian securities regulatory
authorities such amendments and supplements to such registration statement and
the prospectus used in connection therewith as may be necessary to keep such
registration statement effective for such period (which shall not be required to
exceed 120 days in the case of a registration pursuant to Sec-

tion 2.1 or 90 days in the case of a registration pursuant to Section 2.2)
as any seller of Registrable Securities pursuant to such registration statement
may reasonably request and to comply with the provisions of the U.S. Securities
Act or Canadian Securities Laws with respect to the sale or other disposition of
all Registrable Securities covered by such registration statement in accordance
with the intended methods of disposition by the seller or sellers thereof set

in conformity with the requirements of the U.S. Securities Act or Canadian
Securities Laws, and other documents, as such seller and underwriter may
reasonably request in order to facilitate the public sale or other disposition
of the Registrable Securities owned by such seller (the Corporation hereby
consenting to the use in accordance with all applicable laws of each such
registration statement (or amendment or post-effective amendment thereto) and
each such prospectus (or preliminary prospectus or supplement thereto) by each
such seller of Registrable Securities and the underwriters, if any, in
connection with the offering and sale of the Registrable Securities covered by
such registration statement or prospectus);

     (d) use its best efforts to register or qualify the Registrable Securities
covered by such registration statement under such other securities or "blue sky"
laws of such jurisdictions as any sellers of Registrable Securities or any
managing underwriter, if any, shall reasonably request, and do any and all other
acts and things which may be reasonably necessary or advisable to enable such
sellers or underwriter, if any, to consummate the disposition of the Registrable
Securities in such jurisdictions, except that in no event shall the Corporation
be required to qualify to do business as a foreign corporation in any
jurisdiction where it would not, but for the requirements of this paragraph (d),
be required to be so qualified, to subject itself to taxation in any such
jurisdiction or to consent to general service of process in any such
jurisdiction;

     (e) promptly notify each seller of Registrable Securities covered by such
registration statement and each managing underwriter, if any: (i) when the
registration statement, any pre-effective amendment, the prospectus or any
prospectus supplement related thereto or post-effective amendment to the
registration statement has been filed and, with respect to the registration
statement or any post-effective amendment, when the same has become effective,
(ii) of any request by the Commission, any United States state securities
authority or any Canadian securities regulatory authority for amendments or
supplements to the registration statement or the prospectus related thereto or
for additional information, (iii) of the issuance by the Commission or any
Canadian securities regulatory authority of any stop order suspending the
effectiveness of the registration statement or the initiation of any proceedings
for


                                      -12-


<PAGE>

that purpose, (iv) of the receipt by the Corporation of any notification with
respect to the suspension of the qualification of any Registrable Securities for
sale under the securities or "blue sky" laws of any jurisdiction or the
initiation of any proceeding for such purpose, (v) of the existence of any fact
of which the Corporation becomes aware which results in the registration
statement, the prospectus related thereto or any document incorporated therein
by reference containing an untrue statement of a material fact or omitting to

statement therein not misleading, and (vi) if at any time the representations
and warranties contemplated by any underwriting agreement, securities sales
agreement, or other similar agreement relating to the offering shall cease to be
true and correct in all material respects; and, if the notification relates to
an event described in clause (v), the Corporation shall promptly prepare and
furnish to each such seller and each underwriter, if any, a reasonable number of
copies of a prospectus supplemented or amended so that, as thereafter delivered
to the purchasers of such Registrable Securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading;

     (f) comply with all applicable rules and regulations of the Commission or
any Canadian securities regulatory authority, and make generally available to
its security holders, as soon as reasonably practicable after the effective date
of the registration statement (and in any event within 15 months thereafter), an
earnings statement (which need not be audited) covering the period of at least
twelve consecutive months beginning with the first day of the Corporation's
first calendar quarter after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
U.S. Securities Act and Rule 158 thereunder;

     (g) (i) cause all such Registrable Securities covered by such registration
statement to be listed on the principal securities exchange on which similar
securities issued by the Corporation are then listed (if any), if the listing of
such Registrable Securities is then permitted under the rules of such exchange,
or (ii) if no similar securities are then so listed, cause all such Registrable
Securities to be listed on a United States national securities exchange or
secure designation of each such Registrable Security as a Nasdaq National Market
"national market system security" within the meaning of Rule 11Aa2-1 of the
Commission or secure National Association of Securities Dealers Automated
Quotation authorization for such shares and, without limiting the generality of
the foregoing, take all actions that may be required by the Corporation as the
issuer of such Registrable Securities in order to facilitate the arranging for
the registration of at least two market makers as such with respect to such
shares with the National Association of Securities Dealers, Inc. (the "NASD");

     (h) provide and cause to be maintained a transfer agent and registrar for
all such Registrable Securities covered by such registration statement not later

     (i) enter into such customary agreements (including, if applicable, an
underwriting agreement) and take such other actions as the Major Holder (or the
Initiating Holders in the case of a Section 2.1 Demand Registration) shall
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities. The Holders of the Registrable Securities which are to
be distributed by such underwriters shall be parties to such underwriting
agreement and may, at their option, require that the Corporation, and in such
case the Corporation will, make to, and for the benefit of, such Holders the
representations, warranties and covenants of the Corporation which are being
made to, and for the benefit of, such underwriters and which are of the type
customarily provided to institutional investors in secondary offerings;

     (j) obtain an opinion from the Corporation's counsel and a "cold comfort"
letter from the Corporation's independent public accountants in customary form
and covering such matters as are customarily covered by such opinions and "cold
comfort" letters delivered to underwriters in underwritten public offerings,

any, and to the Major Holders participating in such offering, and furnish to
each Holder participating in the offering and to each underwriter, if any, a
copy of such opinion and letter addressed to such Holder or underwriter;

     (k) deliver promptly to each Holder participating in the offering and each
underwriter, if any, copies of all correspondence between the Commission, any
Canadian securities regulatory authority and the Corporation, its counsel or
auditors and all memoranda relating to discussions with the Commission, its
staff, any Canadian securities regulatory authority with respect to the
registration statement, other than those portions of any such correspondence and
memoranda which contain information subject to attorney-client privilege with
respect to the Corporation, and, upon receipt of such confidentiality agreements
as the Corporation may reasonably request, make reasonably available for
inspection by any seller of such Registrable Securities covered by such
registration statement, by any underwriter, if any, participating in any
disposition to be effected pursuant to such registration statement and by any
attorney, accountant or other agent retained by any such seller or any such
underwriter, all pertinent financial and other records, pertinent corporate

with such registration statement;

     (l) use its best efforts to obtain the withdrawal of any order suspending

     (n) make reasonably available its employees and personnel and otherwise
provide reasonable assistance to the underwriters in the marketing of
Registrable Securities in any underwritten offering;

     (o) promptly prior to the filing of any document which is to be
incorporated by reference into the registration statement or the prospectus
(after the initial filing of such registration statement) provide copies of such
document to counsel to the sellers of Registrable Securities and to the managing
underwriter, if any, and make the Corporation's representatives reasonably
available for discussion of such document and make such changes in such document
concerning such sellers prior to the filing thereof as counsel for such sellers
or underwriters may reasonably request;

     (p) furnish to each Holder participating in the offering and the managing
underwriter, without charge, at least one signed copy of the registration
statement and any post-effective amendments thereto, including financial
statements and schedules, all documents incorporated therein by reference and
all exhibits (including those incorporated by reference);

     (q) cooperate with the sellers of Registrable Securities and the managing
underwriter, if any, to facilitate the timely preparation and delivery of
certificates not bearing any restrictive legends representing the Registrable
Securities to be sold, and cause such Registrable Securities to be issued in
such denominations and registered in such names in accordance with the
underwriting agreement prior to any sale of Registrable Securities to the
underwriters or, if not an underwritten offering, in accordance with the
instructions of the sellers of Registrable Securities at least three business
days prior to any sale of Registrable Securities;

     (r) if a Canadian Prospectus is filed in the Province of Quebec, opinions
of Quebec counsel and of the auditors representing the Corporation for the
purposes of such registration relating to translation into the French language
of the applicable registration statement, in form and substance as is
customarily given to underwriters in an underwritten public offering and
reasonably satisfactory to a majority in interest of Holders requesting
registration, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities; and

     (s) take all such other commercially reasonable actions as are necessary or
advisable in order to expedite or facilitate the disposition of such Registrable
Securities.

     The Corporation may require as a condition precedent to the Corporation's
obligations under this Section 2.4 that each seller of Registrable Securities as
to which any registration is being effected furnish the Corporation such
information regarding such seller and the distribution of such securities as the
Corporation may from time to time reasonably request, provided that such
information shall be used only in connection with such registration.


<PAGE>


                                      -15-


     Each Holder of Registrable Securities agrees that upon receipt of any
notice from the Corporation of the happening of any event of the kind described
in clause (v) of paragraph (e) of this Section 2.4, such Holder will discontinue
such Holder's disposition of Registrable Securities pursuant to the registration
statement covering such Registrable Securities until such Holder's receipt of
the copies of the supplemented or amended prospectus contemplated by paragraph
(e) of this Section 2.4 and, if so directed by the Corporation, will deliver to
the Corporation (at the Corporation's expense) all copies, other than permanent
file copies, then in such Holder's possession of the prospectus covering such
Registrable Securities that was in effect at the time of receipt of such notice.
In the event the Corporation shall give any such notice, the applicable period
mentioned in paragraph (b) of this Section 2.4 shall be extended by the number
of days during such period from and including the date of the giving of such
notice to and including the date when each seller of any Registrable Securities
covered by such registration statement shall have received the copies of the
supplemented or amended prospectus contemplated by paragraph (e) of this Section
2.4.

     If any such registration statement or comparable statement under "blue sky"
laws refers to any Holder by name or otherwise as the Holder of any securities
of the Corporation, then such Holder shall have the right to require, acting
reasonably, (i) the insertion therein of language, in form and substance
satisfactory to such Holder, to the effect that the holding by such Holder of
such securities is not to be construed as a recommendation by such Holder of the
investment quality of the Corporation's securities covered thereby and that such
holding does not imply that such Holder will assist in meeting any future
financial requirements of the Corporation, or (ii) in the event that such
reference to such Holder by name or otherwise is not in the judgment of the
Corporation, as advised by counsel, required by the U.S. Securities Act or any
similar federal statute or any state "blue sky" or United States securities law
then in force, the deletion of the reference to such Holder.

     2.5. Registration Expenses.

     (a) "Expenses" shall mean any and all fees and expenses incident to the
Corporation's performance of or compliance with this Article 2, including,
without limitation: (i) Commission, Canadian securities regulatory authorities,
United States or Canadian stock exchange or NASD registration and filing fees
and all listing fees and fees with respect to the inclusion of securities in the
Nasdaq National Market; (ii) fees and expenses of compliance with Securities
Laws or United States "blue sky" laws and in connection with the preparation of
a "blue sky" survey, including, without limitation, reasonable fees and expenses
of blue sky counsel; (iii) printing and copying expenses; (iv) messenger and
delivery expenses; (v) expenses incurred in connection with any road show; (vi)
fees and disbursements of counsel for the Corporation; (vii) with respect to
each registration, the fees and disbursements of one counsel in each of Canada
and the United States, as required, for the sellers of Registrable


<PAGE>


                                      -16-


Securities (selected by the Initiating Holders in the case of a registration
pursuant to Section 2.1, and selected by the Majority Holder in the case of a
registration pursuant to Section 2.2) as well as of one local counsel; (viii)
fees and disbursements of all independent public accountants (including the
expenses of any audit and/or "cold comfort" letter) and fees and expenses of
other persons, including special experts, retained by the Corporation and (ix)
any other reasonable fees and disbursements of underwriters, if any, customarily
paid by issuers.

     (b) The Corporation shall pay all Expenses with respect to any Demand
Registration pursuant to Section 2.1 whether or not such Demand Registration
becomes effective or does not remain effective for the period contemplated by
Section 2.4(b). The Corporation shall pay all Expenses of each Investor with
respect to any registration effected under Section 2.2. Each Holder of
Registrable Securities (other than the Investors) shall pay the expenses
incurred by that Holder with respect to any registration effected pursuant to
Section 2.2 (such expenses shall be allocated among the Holders of Registrable
Securities (other than the Investors or the Investor Affiliates) on a pro rata
basis based on the number of Registrable Securities included in such offering by
a Holder relative to the number of Registrable Securities included in such
offering by all Holders, except to the extent Expenses are attributable to a
Holder or to securities included in an offering by a Holder (other than an
Investor or the Investor Affiliates)).

     (c) Notwithstanding the foregoing, (i) the provisions of this Section 2.6
shall be deemed amended to the extent necessary to cause these expense
provisions to comply with United States "blue sky" laws of each state or the
Securities Laws of any other jurisdiction in which the offering is made and (ii)
in connection with any registration hereunder, each Holder of Registrable
Securities being registered shall pay all underwriting discounts and commissions
and any transfer taxes, if any, attributable to the Registrable Securities, pro
rata with respect to payments of discounts and commissions in accordance with
the number of shares included in the offering by such Holder, and (iii) the
Corporation shall be responsible for all of its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties).

     2.6. Certain Limitations on Registration Rights. In the case of any
registration under Section 2.1 pursuant to an underwritten offering, or in the
case of a registration under Section 2.2 if the Corporation has determined to
enter into an underwriting agreement in connection therewith, all securities to
be included in such registration shall be subject to an underwriting agreement
and no Person may participate in such registration unless such Person agrees to
sell such Person's securities on the basis provided therein and completes and/or
executes all questionnaires and other documents which must be executed in
connection therewith, and provides such other information to the Corporation or
the underwriter as may be necessary to register such Person's securities.

                                      -17-


     2.7. Limitations on Sale or Distribution of Other Securities.

     (a) If requested in writing by the managing underwriter(s), if any, of any
registration effected pursuant to Section 2.1 or 2.2, each Holder of Registrable
Securities agrees not to effect any public sale or distribution, including,
without limitation, any sale pursuant to Canadian Securities Laws or Rule 144
under the U.S. Securities Act, of any Registrable Securities, or of any other
equity security of the Corporation or of any security convertible into or
exchangeable or exercisable for any equity security of the Corporation (other
than as part of such underwritten public offering) during the time period
reasonably requested by the managing underwriter(s), if any, not to exceed 180
days (and the Corporation hereby also so agrees (except that the Corporation may
effect any sale or distribution of any such securities pursuant to a
registration on Form S-4 (if reasonably acceptable to the managing underwriter)
or Form S-8 under the U.S. Securities Act, or any successor or similar form for
a domestic or foreign issuer which is then in effect or upon the conversion,
exchange or exercise of any then outstanding Common Share Equivalent) to cause
each Holder of any equity security or of any security convertible into or
exchangeable or exercisable for any equity security of the Corporation purchased
from the Corporation at any time other than in a public offering so to agree).

     (b) The Corporation hereby agrees that, if it shall previously have
received a request for registration pursuant to Section 2.1 or 2.2, and if such
previous registration shall not have been withdrawn or abandoned, the
Corporation shall not sell, transfer, or otherwise dispose of, any Common
Shares, or any other equity security of the Corporation or any security
convertible into or exchangeable or exercisable for any equity security of the
Corporation (other than as part of such underwritten public offering, a
registration on Form S-4 or Form S-8 under the U.S. Securities Act or any
successor or similar form for a domestic or foreign issuer which is then in
effect or upon the conversion, exchange or exercise of any then outstanding
Common Share Equivalent), until a period of 90 days shall have elapsed from the
effective date of such previous registration; and the Corporation shall so
provide in any registration rights agreements hereafter entered into with
respect to any of its securities.

     2.8. No Required Sale. Nothing in this Agreement shall be deemed to create
an independent obligation on the part of any Holder to sell any Registrable
Securities pursuant to any effective registration statement.

     2.9. Indemnification for Registrations.

     (a) In the event of any registration of any securities of the Corporation
under the U.S. Securities Act or Canadian Securities Laws pursuant to this
Article 2, the Corporation shall, and hereby does, indemnify and hold harmless,
to the fullest extent permitted by law, the Holder of any Registrable
Securities, its directors, officers, fiduciaries, employees and

<PAGE>


                                      -18-


shareholders or general and limited partners (and the directors, officers,
employees and shareholders thereof), each other Person who participates as an
underwriter or a Qualified Independent Underwriter, if any, in the offering or
sale of such securities, each officer, director, employee, shareholder or
partner of such underwriter or Qualified Independent Underwriter, and each other
Person, if any, who controls such seller or any such underwriter within the
meaning of the U.S. Securities Act, or Canadian Securities Laws against any and
all losses, claims, damages or liabilities, joint or several, actions or
proceedings (whether commenced or threatened) in respect thereof and expenses
(including reasonable fees of counsel and any amounts paid in any settlement
effected with the Corporation's consent, which consent shall not be unreasonably
withheld or delayed) to which each such indemnified party may become subject
under the U.S. Securities Act, Canadian Securities Laws or otherwise ("Claims"),
insofar as such Claims arise out of or are based upon (i) any untrue statement
or alleged untrue statement of a material fact contained in any Canadian
Prospectus or registration statement under which such securities were registered
under the U.S. Securities Act or 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, (ii) any untrue statement or alleged untrue
statement of a material fact contained in any preliminary, final or summary
prospectus or any amendment or supplement thereto, together with the documents
incorporated by reference therein, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or (iii) any violation by the Corporation of any
federal, state, provincial, or common law rule or regulation applicable to the
Corporation and relating to action required or inaction of the Corporation in
connection with any such registration, and the Corporation will reimburse any
such indemnified party for any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
Claim as such expenses are incurred; provided, however, that the Corporation
shall not be liable to any such indemnified party in any such case to the extent
such Claim arises solely out of any untrue statement or alleged untrue statement
of a material fact or omission or alleged omission of a material fact made in
such registration statement or amendment thereof or supplement thereto or in any
such prospectus or any preliminary, final or summary prospectus in reliance
upon, and in conformity with, written information furnished to the Corporation
by, or on behalf of, such indemnified party specifically for use therein. Such
indemnity and reimbursement of expenses shall remain in full force and effect
regardless of any investigation made by, or on behalf of, such indemnified party
and shall survive the transfer of such securities by such seller.

     (b) Each Holder of Registrable Securities that are included in the
securities as to which any registration under Section 2.1 or 2.2 is being
effected (and, if required by the Corporation as a condition to including any
Registrable Securities in any registration statement filed in accordance with
Section 2.1 or Section 2.2, any underwriter or Qualified Independent
Underwriter, if any), shall, severally and not jointly, indemnify and hold
harmless (in


<PAGE>


                                      -19-


the same manner and to the same extent as set forth in paragraph (a) of this
Section 2.9) to the extent permitted by law, the Corporation, its officers,
directors, fiduciaries, employees and shareholders or general and limited
partners (and the directors, officers, employees, and shareholders thereof),
each Person controlling the Corporation within the meaning of the U.S.
Securities Act and Canadian Securities Laws with respect to any untrue statement
or alleged untrue statement of any material fact in, or omission or alleged
omission of any material fact from, such registration statement, any
preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto, if such statement or alleged statement or omission or
alleged omission was made in reliance upon, and in conformity with, written
information furnished to the Corporation or its representatives by, or on behalf
of, such Holder or underwriter or Qualified Independent Underwriter, if any,
specifically for use therein and shall reimburse such indemnified party for any
legal or other expenses reasonably incurred in connection with investigating or
defending any such Claim as such expenses are incurred; provided, however, that
the aggregate amount which any such Holder shall be required to pay pursuant to
this Section 2.9(b) and Sections 2.9(c) and (e) shall in no case be greater than
the amount of the net proceeds received by such Holder upon the sale of the
Registrable Securities pursuant to the registration statement giving rise to
such Claim. Such indemnity and reimbursement of expenses shall remain in full
force and effect regardless of any investigation made by, or on behalf of, such
indemnified party and shall survive the transfer of such securities by such
Holder.

     (c) Indemnification similar to that specified in the preceding paragraphs
(a) and (b) of this Section 2.9 (with appropriate modifications) shall be given
by the Corporation and each seller of Registrable Securities with respect to any
required registration or other qualification of securities under any state
securities and "blue sky" laws.

     (d) Any person entitled to indemnification under this Agreement shall
promptly notify the indemnifying party in writing of the commencement of any
action or proceeding with respect to which a claim for indemnification may be
made pursuant to this Section 2.9, but the failure of any indemnified party to
provide such notice shall not relieve the indemnifying party of its obligations
under the preceding paragraphs of this Section 2.9, except to the extent the
indemnifying party is materially prejudiced thereby and shall not relieve the
indemnifying party from any liability which it may have to any indemnified party
otherwise than under this Article 2. In case any action or proceeding is brought
against an indemnified party, it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, unless in the reasonable opinion of outside counsel to the
indemnified party a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such Claim, to assume the defense
thereof jointly with any other indemnifying party similarly notified, to the
extent that it chooses, with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the written consent of the indemnified party,
be counsel to the indemnifying party), and after notice from the

                                      -20-


indemnifying party to such indemnified party that it so chooses, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation; provided,
however, that (i) if the indemnifying party fails to take reasonable steps
necessary to defend diligently the action or proceeding within 20 days after
receiving notice from such indemnified party that the indemnified party believes
it has failed to do so, (ii) if such indemnified party who is a defendant in any
action or proceeding which is also brought against the indemnifying party
reasonably shall have concluded that there may be one or more legal defenses
available to such indemnified party which are not available to the indemnifying
party, or (iii) if representation of both parties by the same counsel is
otherwise inappropriate under applicable standards of professional conduct,
then, in any such case, the indemnified party shall have the right to assume or
continue its own defense as set forth above (but with no more than one firm of
counsel for all indemnified parties in each jurisdiction, except to the extent
any indemnified party or parties reasonably shall have concluded that there may
be legal defenses available to such party or parties which are not available to
the other indemnified parties or to the extent representation of all indemnified
parties by the same counsel is otherwise inappropriate under applicable
standards of professional conduct) and the indemnifying party shall be liable
for any expenses therefor (including, without limitation, any such counsel's
fees). 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 (A) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (B) 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.

     (e) If for any reason the foregoing indemnity is unavailable or is
insufficient to hold harmless an indemnified party under Sections 2.9(a), (b) or
(c), then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party as a result of any Claim in such proportion as is
appropriate to reflect the relative fault of the indemnifying party, on the one
hand, and the indemnified party, on the other hand, with respect to such
offering of securities. 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 indemnifying party or the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. If, however, the
allocation provided in the second preceding sentence is not permitted by
applicable law, then each indemnifying party shall contribute to the amount paid
or payable by such indemnified party in such proportion as is appropriate to
reflect not only such relative faults, but also the relative benefits of the
indemnifying party and the indemnified party, as well as any other relevant eq-

                                      -21-


uitable considerations. The parties hereto agree that it would not be just and
equitable if contributions pursuant to this Section 2.9(e) were to be determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to in the preceding sentences
of this Section 2.9(e). The amount paid or payable in respect of any Claim shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such Claim.
No person guilty of fraudulent misrepresentation (within the meaning of section
11(f) of the U.S. Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. Notwithstanding
anything in this Section 2.9(e) to the contrary, no indemnifying party (other
than the Corporation) shall be required pursuant to this Section 2.9(e) to
contribute any amount in excess of the net proceeds received by such
indemnifying party from the sale of Registrable Securities in the offering to
which the losses, claims, damages or liabilities of the indemnified parties
relate, less the amount of any indemnification payment made pursuant to Sections
2.9(b) and (c).

     (f) The indemnity agreements contained herein shall be in addition to any
other rights to indemnification or contribution which any indemnified party may
have pursuant to law or contract and shall remain operative and in full force
and effect regardless of any investigation made or omitted by, or on behalf of,
any indemnified party and shall survive the transfer of the Registrable
Securities by any such party.

     (g) The indemnification and contribution required by this Section 2.9 shall
be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

     3. Underwritten Offerings.

     3.1. Requested Underwritten Offerings. If requested by the underwriters for
any underwritten offering by the Holders pursuant to a registration requested
under Section 2.1, the Corporation shall enter into a customary underwriting
agreement with the underwriters. Such underwriting agreement shall be
satisfactory in form and substance to the Initiating Holders acting reasonably
and shall contain such representations and warranties by, and such other
agreements on the part of, the Corporation and such other terms as are generally
prevailing in agreements of that type, including, without limitation,
indemnities and contribution agreements. Any Holder participating in the
offering shall be a party to such underwriting agreement and may, at its option,
require that any or all of the representations and warranties made by, and the
other agreements on the part of, the Corporation to, and for the benefit of,
such underwriters shall also be made to, and for the benefit of, such Holder and
that any or all of the conditions precedent


<PAGE>


                                      -22-


to the obligations of such underwriters under such underwriting agreement be
conditions precedent to the obligations of such Holder; provided, however, that
the Corporation shall not be required to make any representations or warranties
with respect to information specifically provided by a selling Holder of
Registrable Securities for inclusion in the registration statement. Such
underwriting agreement shall also contain such representations and warranties by
the participating Holders as are customary in agreements of that type.

     3.2. Piggyback Underwritten Offerings. In the case of a registration
pursuant to Section 2.2 hereof, if the Corporation shall have determined to
enter into any underwriting agreements in connection therewith, all of the
Holders' Registrable Securities to be included in such registration shall be
subject to such underwriting agreements. Any Holder participating in such
registration may, at its option, require that any or all of the representations
and warranties by, and the other agreements on the part of, the Corporation to,
and for the benefit of, such underwriters shall also be made to, and for the
benefit of, such Holder and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of such Holder. Such underwriting agreement shall
also contain such representations and warranties by the participating Holders as
are customary in agreements of that type.

     3.3. Underwriting Services. If a Demand Registration pursuant to Section
2.1 involves an underwritten offering, then the Corporation shall select the
underwriter from underwriting firms of national reputation in the United States
or Canada, as the case may be, subject to the approval of the Initiating
Holders, such approval not to be unreasonably withheld.

     4. General.

     4.1. Adjustments Affecting Registrable Securities. The Corporation agrees
that it shall not effect or permit to occur any combination or subdivision of
shares which would adversely affect the ability of the Holder of any Registrable
Securities to include such Registrable Securities in any registration
contemplated by this Agreement or the marketability of such Registrable
Securities in any such registration. The Corporation agrees that it will take
all reasonable steps necessary to effect a subdivision of shares if in the
reasonable judgment of (a) the Initiating Holders in the case of a Demand
Registration Request, or (b) the Manager for the offering in respect of any such
registration requests, such subdivision would enhance the marketability of the
Registrable Securities. Each Holder agrees to vote all of its share capital in a
manner, and to take all other actions necessary, to permit the Corporation to
carry out the intent of the preceding sentence including, without limitation,
voting in favor of an amendment to the Corporation's Articles of Incorporation
in order to increase the number of authorized capital shares of the Corporation.

                                      -23-


     4.2. Rule 144. If the Corporation shall have filed a registration statement
pursuant to the requirements of Section 12 of the U.S. Exchange Act or a
registration statement pursuant to the requirements of the U.S. Securities Act
in respect of the Common Shares or Common Shares Equivalents, the Corporation
covenants that (a) so long as it remains subject to the reporting provisions of
the Exchange Act, it will timely file the reports required to be filed by it
under the U.S. Securities Act or the Exchange Act (including, without
limitation, the reports under Sections 13 and 15(d) of the Exchange Act referred
to in subparagraph (c)(1) of Rule 144 under the U.S. Securities Act), and (b)
will take such further action as any Holder of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such
Holder to sell Registrable Securities without registration under the U.S.
Securities Act within the limitation of the exemptions provided by (i) Rule 144
under the U.S. Securities Act, as such Rule may be amended from time to time, or
(ii) any similar rule or regulation hereafter adopted by the Commission. Upon
the request of any Holder of Registrable Securities, the Corporation will
deliver to such Holder a written statement as to whether it has complied with
such requirements.

     4.3. Nominees for Beneficial Owners. If Registrable Securities are held by
a nominee for the beneficial owner thereof, the beneficial owner thereof may, at
its option, be treated as the Holder of such Registrable Securities for purposes
of any request or other action by any Holder or Holders of Registrable
Securities pursuant to this Agreement (or any determination of any number or
percentage of shares constituting Registrable Securities held by any Holder or
Holders of Registrable Securities contemplated by this Agreement); provided,
however, that the Corporation shall have received written assurances reasonably
satisfactory to it of such beneficial ownership.

     4.4. Amendments. The terms and provisions of this Agreement may be modified
or amended, or any of the provisions hereof waived, temporarily or permanently,
pursuant to the prior written consent of the Corporation and the party adversely
affected by such modification or waiver.

     4.5. Notices. All notices, requests, consents and other communications
hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or sent by telecopy, nationally
recognized overnight courier or first class registered or certified mail, return
receipt requested, postage prepaid, addressed to such party at the address set
forth below or such other address as may hereafter be designated in writing by
such party to the other parties:

     Each Holder, by written notice given to the Corporation in accordance with
this Section 4.5, may change the address to which such notice or other
communications are to be sent to such Holder. All such notices, requests,
consents and other communications shall be deemed to have been given when
received.

     4.6. Miscellaneous.

     (a) This Agreement shall be binding upon and inure to the benefit of and be
enforceable by the parties hereto and the respective successors, personal
representatives and assigns of the parties hereto, whether so expressed or not.
No Person other than a Holder shall be entitled to any benefits under this
Agreement, except as otherwise expressly provided herein. This Agreement and the
rights of the parties hereunder may be assigned by any of the


<PAGE>


                                      -27-


parties hereto to any transferee of Registrable Securities provided that
upon the consummation of, and as a condition to, any such assignment the
transferee assumes the obligations of the assignor under, and agrees to be bound
by the terms of, this Agreement.

     (b) This Agreement and the other writings referred to herein or delivered
pursuant hereto which form a part hereof contain the entire agreement among the
parties with respect to the subject matter hereof and supersede all prior and
contemplated arrangements and understandings with respect thereto, including but
not limited to, that certain letter of intent, dated as of August 5, 1999,
between the Corporation and the Investors.

     (c) This Agreement shall be governed by and construed in accordance with
the laws of the State of New York without giving effect to the principles of
conflicts of law thereof.

     (d) The headings of the sections of this Agreement have been inserted for
convenience of reference only and shall not be deemed to be a part of this
Agreement.

     (e) This Agreement may be executed in any number of counterparts, and each
such counterpart hereof shall be deemed an original instrument, but all such
counterparts together shall constitute but one instrument.

     (f) Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid, but if any provision of
this Agreement is held to be invalid or unenforceable in any respect, such
invalidity or unenforceability shall not render invalid or unenforceable any
other provision of this Agreement.

     (g) It is hereby agreed and acknowledged that it will be impossible to
measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the event
of any such failure, an aggrieved person will be irreparably damaged and will
not have an adequate remedy at law. Any such person, therefore, shall be
entitled to injunctive relief, including specific performance, to enforce such
obligations, without the posting of any bond, and, if any action should be
brought in equity to enforce any of the provisions of this Agreement, none of
the parties hereto shall raise the defense that there is an adequate remedy at
law.

     (h) Each party hereto shall do and perform or cause to be done and
performed all such further acts and things and shall execute and deliver all
such other agreements, certificates, instruments, and documents as any other
party hereto reasonably may request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the

          shall not amend or otherwise alter any obligations to be assumed by
          Newco pursuant to the terms of the Terms of Purchase without the prior
          written consent of the Purchaser being obtained. The Purchaser may

          Purchased Strands for the transmission of telecommunication services
          (such equipment being referred to herein as the "Equipment"). The
          Sellers shall allow the Purchasers reasonable access to their shelters
          and to the Purchased Strands to allow installation of the Equipment.
          In the event that completion of the share purchase transaction
          contemplated herein fails to complete on or prior to the Share Closing
          Date, the Purchaser shall, at its option, exercisable by written
          notice (the "Equipment Notice") delivered by the Purchaser to the
          Sellers, either:

          (i)  remove the Equipment and restore the Purchased Strands to the
               condition existing immediately prior to installation of the
               Equipment; or

               the lesser of (A) fair market value of the Equipment at the time

<PAGE>
                                      -4-


     (a)  Ledcor and Newco confirm and declare that the purchase price has been
          calculated based on (x) the price paid by MetroNet to Ledcor and
          fONOROLA for the transfer of certain fiber assets, and (y) deducting
          therefrom the anticipated cost of performing certain obligations to be
          assumed by Newco hereunder. It is the intention of Ledcor and Newco
          that the transfer of the Fiber Assets be effected on economic terms
          equivalent to the terms, responsibilities and arrangements between
          Ledcor, fONOROLA and MetroNet relating to the transfer by Ledcor and
          fONOROLA to MetroNet of such fiber assets.

     (b)  Accordingly, following Closing the parties shall adjust between
          themselves, from time to time at and after the Closing, with respect
          to the following matters:

          (i)  Ledcor and Newco shall each pay to the other such amounts as may
               be necessary, acting reasonably, to effect the intent described
               in subsection 5(a).

          (ii) Without limiting the generality of the foregoing, all costs,
               expenses and payments which relate to the cost of the builds
               including, without limitation, right-of-way and similar charges
               (for clarity, including without limitation those relating to WFI
               or any other purchaser of fiber assets and, in respect of all
               rights-of-way and similar charges, for the term expiring on March
               1, 2018), construction costs, holdbacks, warranty claims and all
               costs of performing any assumed obligations where Newco has not
               received the associated revenue, shall be paid by Ledcor. For
               greater certainty, this obligation shall continue indefinitely,
               but Ledcor shall remain responsible for all right-of-way payments
               relating to or necessary for the sale of fiber stands to MetroNet
               or to Newco in respect of the initial term expiring March 1,
               2018.

          (iii) Without limiting the generality of the foregoing, with respect
               to the obligation of fONOROLA to make ongoing right-of-way
               payments to CPR, and the obligation of Ledcor to reimburse
               fONOROLA for 50% of such payments, all such amounts shall be paid
               by Ledcor, and Ledcor shall be entitled to any surplus which may
               arise under (and Ledcor shall pay any deficiency in relation to)
               the amounts held in trust by Stikeman, Elliott to secure the
               obligation to CPR.

          (iv) Except as expressly provided above, the parties shall adjust any
               prepaid or accrued amounts owing pursuant to the Assumed
               Contracts,

<PAGE>
                                      -5-


               and all costs and revenue associated with the Assumed
               Contracts, with Ledcor to be responsible for all costs and
               expenses and to receive all benefits attributable to the period
               prior to the Closing Date and Newco to be responsible for all
               costs and expenses and to receive all benefits attributable to
               the period as of and from the Closing Date. For greater
               certainty, Ledcor acknowledges it has prepaid amounts relating to
               obligations which Newco will covenant to perform under the terms
               of the Assignment and Assumption Agreements. In finalizing
               adjustments between the parties, these amounts shall be pro rated
               to the Closing Date and shall be credited to Newco.

          (v)  Except as expressly provided above, as of the Closing Date, there
               shall also be adjusted between Ledcor and Newco, utility rates
               and charges, other income from the Fiber Assets, taxes,
               insurance, other amounts received from purchasers, licensees and
               tenants, 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 Ledcor shall pay
               all expenses and receive all income relative to the Fiber Assets
               prior to the Closing Date and Newco shall bear and pay all
               expenses and receive all income relative to the Fiber Assets from
               and including the Closing Date.

          (vi) Newco shall be responsible for payment of all taxes, rates,
               duties, assessments and charges levied, rated, charged or
               assessed in respect of the Fiber Assets that are payable in
               respect of all periods of time from and after the Closing Date,
               and Ledcor shall be responsible for payment of all taxes, rates,
               duties, assessments and charges levied, rated, charged or
               assessed in respect of the Fiber Assets that are payable in
               respect of all periods of time before the Closing Date.

          (vii) The parties agree that assumption of the commitment in the Build
               Agreements to supply 12 fiber strands between Portland and Los
               Angeles to fONOROLA has been reflected in the calculation of the
               Purchase Price and there will be no adjustment between the
               parties with respect to such assumed obligation.

Dear Sirs/Mesdames:

                    Re: Transfer for Fiber from Ledcor to WFI

     Reference is made to the Amended and Restated Share Purchase Agreement
dated as of September 7, 1999 (the "Share Purchase Agreement") between Ledcor
Industries Limited ("LIL"), Ledcor Industries Inc.("LII", and together with LIL,
"Ledcor") and Worldwide Fiber Inc. ("WFI") and the Asset Purchase Agreement
dated as of September 27, 1999 (the "Asset Purchase Agreement") between LIL, LII
and Worldwide Fiber (F.O.T.S.) No. 3, Ltd. ("Newco").

     For the purposes of this letter agreement, all other capitalized terms not
otherwise defined herein shall have the meanings ascribed thereto in the Share
Purchase Agreement.

     Ledcor, Newco and WFI have agreed to amend certain items of the Share
Purchase Agreement and the Asset Purchase Agreement in order to take advantage
of certain tax planning and other opportunities not contemplated in the
agreements and to confirm the parties understanding with respect to access to
the Marine Strands (as defined herein).

     In connection with the foregoing, Ledcor, Newco and WFI have agreed as
follows:

     1. With respect to the Share Purchase Agreement, the parties hereto agree
as follows:

     (a)  LIL and LII hereby authorize and direct WFI to issue 4,500,000 WFI
          Shares to LIL on the Share Closing, rather than to the Sellers as
          stated in Section 3.1;

     (b)  the representation of Ledcor contained in Section 4.1(f) is hereby
          amended to read as follows:


<PAGE>
                                      -2-


          "(f) Status of Newco Shares. Subsequent to the Roll-In Transaction and
               immediately prior to the Share Closing the Newco Shares shall be
               issued in the name of Ledcor Industries Limited as the registered
               and beneficial owner thereof with good and marketable title
               thereto, free and clear of all mortgages, liens, charges,
               pledges, security interests, encumbrances or other claims
               whatsoever, other than rights in favour of the Purchaser pursuant
               to this Share Purchase Agreement; each of the Sellers has the
               right, power and authority to enter into this Agreement and
               Ledcor Industries Limited has the right, power and authority to
               sell all the Newco Shares on the Share Closing, and the delivery
               of such Newco Shares by Ledcor Industries Limited to the
               Purchaser pursuant to the provisions hereof will transfer to the
               Purchaser valid title thereto, free and clear of all
               Encumbrances."

     2. With respect to the Asset Purchase Agreement, the parties hereto agree
as follows:

     (a)  The Purchase Price shall be allocated as agreed between Newco, LIL and
          LII, within 20 days of the date hereof :

          The value of the assumed commitment in the Build Agreements to supply
          12 fiber strands between Portland and Los Angeles to fONOROLA (the
          "Portland-Los Angeles Build Obligation") shall be US$30,000,000.

          Ledcor and Newco, in filing their respective Canadian and United
          States income tax returns, will use the allocations of the Purchase
          Price and the value of the Portland-Los Angeles Build Operation as set
          forth above.

     (b)  LIL and Newco will each execute a GST closely related corporation
          election under the Excise Tax Act (Canada) with respect to the sale
          and purchase of the Fiber Assets.

     (c)  LIL and Newco will, if requested in writing by either LIL or Newco,
          each execute an election under section 22 of the Income Tax Act
          (Canada) as to the sale of any accounts receivable of LIL purchased
          under the Asset Purchase Agreement, will designate therein the
          applicable portion of the Purchase Price as the consideration paid by
          Newco there-


<PAGE>
                                      -3-


          for and will each file such election with Revenue Canada forthwith
          after the Closing Date.

     (d)  LIL and LII hereby authorize and direct Newco to issue one (1) share
          certificate representing 999 Newco Common Shares to LIL rather than to
          Ledcor as stated in Section 4.

     (e)  Section 1.1(c) is hereby amended to read as follows:

          "(c) "Assumed Contracts" means those agreements which are specified in
               Exhibit 2 to this Agreement together with the Build Agreements;"

     (f)  Notwithstanding the definition of Fiber Assets as found in Section
          1.1(h) of the Asset Purchase Agreement, neither the Fiber Assets nor
          the Purchased Strands (including for the purposes of the Assignment
          and Assumption Agreements) shall include the fiber optic strands which
          are part of an underwater cable in the marine build identified in
          Exhibit 1 to the Asset Purchase Agreement as
          "Vancouver-Victoria-Seattle (Marine)" (the "Marine Strands") or any
          Underlying Rights for the Marine Strands. As a result, the reference
          to the Marine Strands in Exhibit 1 to the Asset Purchase Agreement is
          hereby deleted. The parties further agree that Section 2 is hereby
          amended to read as follows:

          "2.  Purchase and Sale

               On Closing Ledcor shall transfer to Newco the Fiber Assets free
          and clear of all liens, charges and encumbrances save for the
          Permitted Encumbrances and grant indefeasible rights of use ("IRU's")
          to Newco in respect of the submarine strands (the "Marine Strands")
          that connect the terrestrial portions of the fiber optic network from
          Vancouver, B.C. to Victoria, B.C. to Seattle, Washington which
          terrestrial strands are identified on Exhibit 1 attached hereto and
          Newco shall purchase such Fiber Assets and IRU's for an aggregate
          purchase price of $75,000,000 (U.S.) in accordance with the terms and
          conditions set out in this Purchase Agreement."

     (g)  With respect to Section 10.1(a), (i) LIL shall execute and deliver a
          Bill of Sale for the Purchased Strands (as such term is amended by
          paragraph (e) above) located in Canada as identified by the parties in
          a schedule attached to such Bill of Sale; and (ii) LII and LIL shall
          execute


<PAGE>
                                      -4-


          and deliver a Bill of Sale for the Purchased Strands (as such term is
          amended by paragraph (e) above) located in the United States as
          identified by the parties in a schedule attached to such Bill of Sale.

     (h)  With respect to Section 10.1(a), (i) LIL shall execute and deliver an
          Assignment and Assumption Agreement for the Assumed Contracts relating
          to the Fiber Assets (as such term is amended by paragraph (e) above)
          in Canada as identified by the parties in a schedule attached to such
          Assignment and Assumption Agreement; and (ii) LII shall execute and
          deliver an Assignment and Assumption Agreement for the Assumed
          Contracts relating to the Fiber Assets (as such term is amended by
          paragraph (e) above) in the United States as identified by the parties
          in a schedule attached to such Assignment and Assumption Agreement.

     (i)  The certificates referred to in Section 10.1(c) and Section 10.2(c)
          are not required to be delivered as the Asset Purchase Agreement is
          dated the day of Closing.

     (j)  On Closing, (i) LIL shall execute and deliver an IRU with respect to
          the Marine Strands located in Canada as identified by the parties in a
          schedule attached to such IRU; and (ii) LII and LIL shall execute and
          deliver an IRU with respect to the Marine Strands located in the
          United States as identified by the parties in a schedule attached to
          such IRU. Such IRU's shall provide for the ultimate transfer of the
          Marine Strands to Newco, an option to acquire the Marine Strands at
          any time subject to certain indemnification obligations of Newco, and
          the granting of a collateral security interest in the Marine Strands
          only to secure such option rights. As required by Section 7.1(b) of
          the Share Purchase Agreement, WFI hereby consents to the granting of
          such security interest and related registrations. If requested by
          Newco, acting reasonably, LIL and LII shall grant a separate security
          agreement, in a form acceptable to LIL and LII, acting reasonably, to
          Newco to grant a security interest in the assets described in the
          IRU's as being the collateral, and shall execute and deliver such
          additional documents, instruments and other assurances as may be
          reasonably requested by Newco, in forms acceptable to LIL and LII,
          acting reasonably.

     (k)  Notwithstanding Section 9, Ledcor shall cause the tangible Fiber
          Assets to be adequately insured up to day on which WFI obtains
          insurance policies (the "Replacement Policies") with respect to the
          tangible Fiber Assets. WFI agrees to obtain the Replacement Policies
          as soon as rea-


<PAGE>
                                      -5-


          sonably practicable after Closing but in no event later than 90 days
          after Closing after which time Ledcor may cancel its policies (the
          "Policies") as they relate to the tangible Fiber Assets. WFI agrees to
          reimburse Ledcor for any premiums incurred by Ledcor under the
          Policies allocated to the tangible Fiber Assets for the period
          following Closing until WFI obtains the Replacement Policies or Ledcor
          cancels the Policies in accordance herewith, which ever is earlier.

     (l)  As required by Exhibit 4 of the Asset Purchase Agreement, WFI confirms
          that it has consented to the terms of the restrictions on transfer of
          the Newco Common Shares which are contained in the constating
          documents of Newco, copies of which WFI acknowledges having received
          and reviewed.

     3. Pursuant to the terms of the Asset Purchase Agreement, (a) LIL hereby
transfers to Newco any and all beneficial interests it holds in the land in
Rocky Inlet (Ontario) and Pefferlaw (Ontario), and (b) LII and LIL hereby
transfer to Newco any and all beneficial interests held by them in the land at
Point Roberts (State of Washington) and Whidbey Island (State of Washington),
for the purposes of installing certain communications shelters forming part of
the Fiber Assets. Each of LII and LIL covenants to execute and deliver such
additional conveyances, transfers and other assurances as may be reasonably
required by Newco after Closing to transfer any and all legal interest in such
land to Newco.

     4. Ledcor undertakes and agrees with Newco that all warranties and
guarantees from material suppliers, equipment makers or subcontractors are
hereby extended to include Newco as a beneficiary thereof (as may be permitted
by such underlying agreements) to the extent of Newco's interest in the Fiber
Assets.

     5. Newco further agrees that in order to assist LIL and LII to preserve any
remedy, right or defence which LIL or LII could have sought, asserted or claimed
as a party to an Assumed Contract, Newco shall comply with any reasonable
request made by LIL or LII in the furtherance of the seeking of such a remedy,
assertion of such a right or claiming of such a defence and, at LIL's or LII's,
as the case may be, expense, Newco shall cooperate with LIL or LII in the
enforcement of such a remedy or right. Notwithstanding the foregoing, Newco
shall not be obligated to perform any act which would materially prejudice
Newco.

     6. Except as amended hereby, the parties confirm and agree that the Share
Purchase Agreement and the Asset Purchase Agreement continue in full force and
effect.

     7. This letter agreement shall be governed by and construed in accordance
with the laws of the Province of British Columbia and the laws of Canada
applicable therein.

     8. This letter agreement, the Share Purchase Agreement and the Asset
Purchase Agreement, along with the other agreements and documents referred to
herein and therein, constitute the entire agreement between the parties with
respect to the subject matter hereof. If there is any conflict or inconsistency
between the provisions of this letter agreement and the provisions of the Share
Purchase Agreement and the Asset Purchase Agreement, the rights and obligations
of the parties shall be governed by the provisions of this letter agreement. No
amendment or variation of this letter agreement shall be valid or binding unless
set forth in writing duly executed by the parties hereto.

     9. Save as specifically provided in the Share Purchase Agreement with
respect to Newco designating affiliates who may acquire all or some of the Fiber
Assets, neither party may assign their rights or obligations pursuant to this
letter agreement without the prior written consent of the other, not to be
unreasonably withheld or delayed. This letter agreement shall enure to the
benefit of and be binding upon the parties hereto and their respective
administrators, successors and permitted assigns.

     10. From time to time subsequent to the date hereof the parties shall
execute and deliver such additional conveyances, transfers and other assurances
as may be reasonably required to carry out the intent and effect of this letter
agreement.

     11. This letter agreement and any amendment, supplement, restatement or
termination of any provision of this letter agreement may be executed and
delivered in any number of counterparts, each of which when executed and
delivered is an original but all of which taken together constitute one and the
same instrument.

     12. This letter agreement may be executed by facsimile and the facsimile
execution pages will be binding upon the executing party to the same extent as
the original executed pages. The executing party covenants to provide originals
of the facsimile execution pages for insertion into the original letter
agreement in place of the facsimile pages.

   Delivery of this instrument to an address other than as set forth above, or
      transmission of instructions other than as set forth above, will not
                          constitute a valid delivery.

         The undersigned acknowledges that he or she has received and reviewed
the Prospectus, dated            , 1999 (the "Prospectus"), of Worldwide Fiber
Inc., a company organized under the laws of Alberta, and this Letter of
Transmittal, which together constitute the Company's offer (the "Exchange
Offer") to exchange up to $500,000,000 aggregate principal amount of the
Company's 12% Senior Notes Due 2009 (the "New Notes"), which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
for a like principal amount of the Company's issued and outstanding 12% Senior
Notes Due 2009 (the "Old Notes"), which have not been so registered.

         For each Old Note accepted for exchange, the registered holder of such
Old Note (collectively with all other registered holders of Old Notes, the
"Holders") will receive a New Note having a principal amount equal to that of
the surrendered Old Note. Registered holders of New Notes on the relevant record
date for the first interest payment date following the consummation of the
Exchange Offer will receive interest accruing from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid, from ,
1999. Old Notes accepted for exchange will cease to accrue interest from and
after the date of consummation of the Exchange Offer. Accordingly, Holders whose
Old Notes are accepted for exchange will not receive any payment in respect of
accrued interest on such Old Notes otherwise payable on any interest payment
date the record date for which occurs on or after consummation of the Exchange
Offer.

         This Letter of Transmittal is to be completed by a Holder of Old Notes
either if certificates are to be forwarded herewith or if a tender of
certificates for Old Notes, if available, is to be made by book-entry transfer
to the account maintained by the Exchange Agent at The Depository Trust Company
(the "Book-Entry Transfer Facility") pursuant to the procedures set forth in
"The Exchange Offer--Acceptance of Old Notes for Exchange; Delivery of New
Notes" section of the Prospectus. Holders of Old Notes whose certificates are
not immediately available, or who are unable to deliver their certificates or
confirmation of the book-entry tender of their Old Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility (a "Book-Entry
Confirmation") and all other documents required by this Letter of Transmittal to
the Exchange Agent on or prior to the Expiration Date, must tender their Old
Notes according to the guaranteed delivery procedures set forth in "The Exchange
Offer--Guaranteed Delivery Procedures" section of the Prospectus. See
Instruction 1. Delivery of documents to the Book-Entry Transfer Facility does
not constitute delivery to the Exchange Agent.

      The undersigned has completed the appropriate boxes below and signed
       this Letter of Transmittal to indicate the action the undersigned
              desires to take with respect to the Exchange Offer.


<PAGE>


               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of Old
Notes indicated below. Subject to, and effective upon, the acceptance for
exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns
and transfers to, or upon the order of, the Company all right, title and
interest in and to such Old Notes as are being tendered hereby.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim when the same are accepted by the Company. The
undersigned hereby further represents that any New Notes acquired in exchange
for Old Notes tendered hereby will have been acquired in the ordinary course of
business of the person receiving such New Notes, whether or not such person is
the undersigned, that neither the Holder of such Old Notes nor any such other
person has an arrangement or understanding with any person to participate in a
distribution of such New Notes and that neither the Holder of such Old Notes nor
any such other person is an "affiliate" (as defined in Rule 405 under the
Securities Act) of the Company.

         The undersigned also acknowledges that this Exchange Offer is being
made in reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, that the New Notes issued pursuant to the Exchange Offer in exchange
for the Old Notes may be offered for resale, resold and otherwise transferred by
a Holder thereof (other than a Holder that is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act) without compliance with
the registration and prospectus delivery provisions of the Securities Act,
provided that such New Notes are acquired in the ordinary course of such
Holder's business and such Holder has no arrangement with any person to
participate in a distribution of such New Notes. However, the SEC has not
considered the Exchange Offer in the context of a no-action letter and there can
be no assurance that the staff of the SEC would make a similar determination
with respect to the Exchange Offer as in other circumstances. If the undersigned
is not a broker-dealer, the undersigned represents that it is not engaged in,
and does not intend to engage in, a distribution of New Notes and has no
arrangement or understanding to participate in a distribution of New Notes. If
any Holder is an affiliate of the Company, is engaged in or intends to engage
in, or has any arrangement or understanding with any person to participate in, a
distribution of the New Notes to be acquired pursuant to the Exchange Offer,
such Holder could not rely on the applicable interpretations of the staff of the
SEC and must comply with the registration and prospectus delivery requirements
of the Securities Act in connection with any resale transaction. If the
undersigned is a broker-dealer that will receive New Notes for its own account
in exchange for Old Notes that were acquired as a result of market-making
activities or other trading activities, it acknowledges that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Notes. However, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

         The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter of Transmittal and every
obligation of the undersigned hereunder shall be binding upon the successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in "The Exchange
Offer--Withdrawal of Tenders" section of the Prospectus.

         Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" herein, please issue the New Notes (and, if applicable, substitute
certificates representing Old Notes for any Old Notes not exchanged) in the name
of the undersigned or, in the case of a book-entry delivery of Old Notes, please
credit the account indicated below maintained at the Book-Entry Transfer
Facility. Similarly, unless otherwise indicated under the box entitled "Special
Delivery Instructions" herein, please send the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not exchanged)
to the undersigned at the address shown in the box herein entitled "Description
of Old Notes Delivered."

         Holders whose certificates for Old Notes are not immediately available
or who cannot deliver their certificates and all other required documents to the
Exchange Agent on or prior to the Expiration Date, or who cannot complete the
procedure for book-entry transfer on a timely basis, may tender their Old Notes
pursuant to the guaranteed delivery procedures set forth in "The Exchange
Offer--Guaranteed Delivery Procedures" section of the Prospectus. Pursuant to
such procedures, (i) such tender must be made through an Eligible Institution,
(ii) on or prior to 5:00 p.m., New York City time, on the Expiration Date, the
Exchange Agent must receive from such Eligible Institution a properly completed
and duly executed Letter of Transmittal (or a facsimile thereof) and Notice of
Guaranteed Delivery, substantially in the form provided by the Company (by
telegram, telex, facsimile transmission, mail or hand delivery), setting forth
the name and address of the holder of Old Notes and the amount of Old Notes
tendered, stating that the tender is being made thereby and guaranteeing that
within three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and any other documents required by this
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent, and (iii) the certificates for all physically tendered Old
Notes, in proper form for transfer, or Book-Entry Confirmation, as the case may
be, and any other documents required by this Letter of Transmittal, are
deposited by the Eligible Institution within three NYSE trading days after the
date of execution of the Notice of Guaranteed Delivery.

         The method of delivery of this Letter of Transmittal, the Old Notes and
all other required documents is at the election and risk of the tendering
Holders, but delivery will be deemed made only upon actual receipt or
confirmation by the Exchange Agent. If Old Notes are sent by mail, it is
suggested that the mailing be registered mail, properly insured, with return
receipt requested, and made sufficiently in advance of the Expiration Date to
permit delivery to the Exchange Agent prior to 5:00 p.m., New York City time, on
the Expiration Date.

         See "The Exchange Offer" section of the Prospectus.

2.       PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS WHO TENDER BY BOOK-ENTRY
         TRANSFER).

         If less than all of the Old Notes evidenced by a submitted certificate
are to be tendered, the tendering Holder(s) should fill in the aggregate
principal amount of Old Notes to be tendered in the box above entitled
"Description of Old Notes -- Principal Amount Tendered." A reissued certificate
representing the balance of

nontendered Old Notes will be sent to such tendering Holder, unless otherwise
provided in the appropriate box of this Letter of Transmittal, promptly after
the Expiration Date. See Instruction 4. All of the Old Notes delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.

3.       SIGNATURES ON THIS LETTER, BOND POWERS AND ENDORSEMENTS, GUARANTEE OF
         SIGNATURES.

         If this Letter of Transmittal is signed by the Holder of the Old Notes
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificates without any change whatsoever.

         If any tendered Old Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

         If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this letter as there are different registrations of certificates.

         When this Letter of Transmittal is signed by the Holder or Holders of
the Old Notes specified herein and tendered hereby, no endorsements of
certificates or separate bond powers are required. If however, the New Notes are
to be issued, or any untendered Old Notes are to be reissued, to a person other
than the Holder, then endorsements of any certificates transmitted hereby or
separate bond powers are required. Signatures on such certificates(s) must be
guaranteed by an Eligible Institution.

         If this Letter of Transmittal is signed by a person other than the
Holder or Holders of any certificate(s) specified herein, such certificate(s)
must be endorsed or accompanied by appropriate bond powers, in either case
signed exactly as the name or names of the Holder or Holders appear(s) on the
certificate(s) and signatures on such certificate(s) must be guaranteed by an
Eligible Institution.

         If this Letter of Transmittal or any certificates or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.

         ENDORSEMENTS ON CERTIFICATES FOR OLD NOTES OR SIGNATURES ON BOND POWERS
REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FINANCIAL INSTITUTION
(INCLUDING MOST BANKS, SAVINGS AND LOAN ASSOCIATIONS AND BROKERAGE HOUSES) THAT
IS A PARTICIPANT IN THE SECURITIES TRANSFER AGENTS MEDALLION PROGRAM, THE NEW
YORK STOCK EXCHANGE MEDALLION SIGNATURE PROGRAM OR THE STOCK EXCHANGES MEDALLION
PROGRAM (EACH, AN "ELIGIBLE INSTITUTION").

         SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE
INSTITUTION, PROVIDED THE OLD NOTES ARE TENDERED: (I) BY A REGISTERED HOLDER OF
OLD NOTES (WHICH TERM, FOR PURPOSES OF THE EXCHANGE OFFER, INCLUDES ANY
PARTICIPANT IN THE BOOK-ENTRY TRANSFER FACILITY SYSTEM WHOSE NAME APPEARS ON A
SECURITY POSITION LISTING AS THE HOLDER OF SUCH OLD NOTES) WHO HAS NOT COMPLETED
THE BOX ENTITLED "SPECIAL ISSUANCE INSTRUCTIONS" OR "SPECIAL DELIVERY
INSTRUCTIONS" ON THIS LETTER, OR (II) FOR THE ACCOUNT OF AN ELIGIBLE

         Tendering Holders of Old Notes should indicate in the applicable box
the name and address to which New Notes issued pursuant to the Exchange Offer
and/or substitute certificates evidencing Old Notes not exchanged are to be
issued or sent, if different from the name or address of the person signing this
Letter of Transmittal. In the case of issuance in a different name, the employer
identification or social security number of the person named must also be
indicated. Holders tendering Old Notes by book-entry transfer may request that
Old Notes not exchanged be credited to such account maintained at the Book-Entry
Transfer Facility as such Holder may designate hereon. If no such instructions
are given, such Old Notes not exchanged will be returned to the name and address
of the person signing this Letter of Transmittal.

5.       TRANSFER TAXES.

         The Company will pay all transfer taxes, if any, applicable to the
transfer of Old Notes to it or its order pursuant to the Exchange Offer. If,
however, New Notes and/or substitute Old Notes not exchanged are to be delivered
to, or are to be registered or issued in the name of, any person other than the
Holder of the Old Notes tendered hereby, or if tendered Old Notes are registered
in the name of any person other than the person signing this Letter of
Transmittal, or if a transfer tax is imposed for any reason other than the
transfer of Old Notes to the Company or its order pursuant to the Exchange
Offer, the amount of any such transfer taxes (whether imposed on the registered
holder or any other persons) will be payable by the tendering Holder. If
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed to such
tendering Holder and the Exchange Agent will retain possession of an amount of
New Notes with a face amount equal to the amount of such transfer taxes due by
such tendering Holder pending receipt by the Exchange Agent of the amount of
such taxes.

         Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter of
Transmittal.

6.       WAIVER OF CONDITIONS.

         The Company reserves the absolute right to waive satisfaction of any or
all conditions enumerated in the Prospectus.

7.       NO CONDITIONAL TENDERS.

         No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering Holders of Old Notes, by execution of this Letter of
Transmittal, shall waive any right to receive notice of the acceptance of their
Old Notes for exchange.

         Although the Company intends to notify Holders of defects or
irregularities with respect to tenders of Old Notes, neither the Company, the
Exchange Agent nor any other person shall incur any liability for failure to
give any such notice.

8.       MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES.

         Any Holder whose Old Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.

9.       WITHDRAWAL OF TENDERS.

         Tenders of Old Notes may be withdrawn at any time prior to 5:00 P.M.,
New York City time, on the Expiration Date. For a withdrawal to be effective, a
written notice of withdrawal must be received by the Exchange Agent at one of
the addresses set forth above. Any such notice of withdrawal must specify the
name of the person having tendered the Old Notes to be withdrawn, identify the
Old Notes to be withdrawn (including the principal amount of such Old Notes),
and (where certificates for Old Notes have been transmitted) specify the name in
which such Old Notes are registered, if different from that of the withdrawing

                                      -4-


Holder. If certificates for Old Notes have been delivered or otherwise
identified to the Exchange Agent, then prior to the release of such certificates
the withdrawing Holder must also submit the serial numbers of the particular
certificates to be withdrawn and a signed notice of withdrawal with signatures
guaranteed by an Eligible Institution unless such Holder is an Eligible
Institution in which case such guarantee will not be required. If Old Notes have
been tendered pursuant to the procedure for book-entry transfer described above,
any notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Old Notes and
otherwise comply with the procedures of such facility. All questions as to the
validity, form and eligibility (including time of receipt) of such notices will
be determined by the Company, whose determination will be final and binding on
all parties. Any Old Notes so withdrawn will be deemed not to have been validly
tendered for exchange for purposes of the Exchange Offer. Any Old Notes which
have been tendered for exchange but which are not exchanged for any reason will
be returned to the Holder thereof without cost to such Holder (or, in the case
of Old Notes tendered by book-entry transfer into the Exchange Agent's account
at the Book-Entry Transfer Facility pursuant to the book-entry transfer
procedures described above, such Old Notes will be credited to an account
maintained with such Book-Entry Transfer Facility for the Old Notes) as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Old Notes may be retendered by following one of the
procedures set forth in "The Exchange Offer--Procedures for Tendering Old Notes"
section of the Prospectus at any time on or prior to the Expiration Date.

10.      REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

                            IMPORTANT TAX INFORMATION

         Under current United States federal income tax law, a Holder of New
Notes is required to provide the Company (as payor) with such Holder's correct
taxpayer identification number ("TIN") on Substitute Form W-9 or otherwise
establish a basis for exemption from backup withholding to prevent backup
withholding on any New Notes delivered pursuant to the Exchange Offer and any
payments received in respect of the New Notes. If a Holder of New Notes is an
individual, the TIN is such holder's social security number. If the Company is
not provided with the correct taxpayer identification number, a Holder of New
Notes may be subject to a $50 penalty imposed by the Internal Revenue Service.
Accordingly, each prospective Holder of New Notes to be issued pursuant to
Special Issuance Instructions should complete the attached Substitute Form W-9.
The Substitute Form W-9 need not be completed if the box entitled Special
Issuance Instructions has not been completed.

         Certain Holders of New Notes (including, among others, all corporations
and certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt prospective Holders of New Notes should indicate
their exempt status on Substitute Form W-9. A foreign individual may qualify as
an exempt recipient by submitting to the Company, through the Exchange Agent, a
properly completed Internal Revenue Service Form W-8 (which the Exchange Agent
will provide upon request) signed under penalty of perjury, attesting to the
Holder's exempt status. See the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional
instructions.

         If backup withholding applies, the Company is required to withhold 31%
of any payment made to the Holder of New Notes or other payee. Backup
withholding is not an additional United States federal income tax. Rather, the
United States federal income tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the Internal
Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

         To prevent backup withholding on any New Notes delivered pursuant to
the Exchange Offer and any payments received in respect of the New Notes, each
prospective Holder of New Notes to be issued pursuant to Special Issuance
Instructions should provide the Company, through the Exchange Agent, with
either: (i) such prospective Holder's correct TIN by completing the form below,
certifying that the TIN provided on Substitute Form W-9 is correct (or that such
prospective Holder is awaiting a TIN) and that (A) such prospective Holder has
not been notified by the Internal Revenue Service that he or she is subject to
backup withholding as a result of a failure to report all interest or dividends
or (B) the Internal Revenue Service has notified such prospective Holder that he
or she is no longer subject to backup withholding; or (ii) an adequate basis for
exemption.

WHAT NUMBER TO GIVE THE EXCHANGE AGENT

         The prospective Holder of New Notes to be issued pursuant to Special
Issuance Instructions is required to give the Exchange Agent the TIN (e.g.,
social security number or employer identification number) of the prospective
record owner of the New Notes. If the New Notes will be held in more than one
name or are not held in the name of the actual owner, consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional guidance regarding which number to report.
