                                Based  on  positions  of  the   Securities   and
                                Exchange    Commission    and    no-action    or

                                        or  understanding  with  any  person  to

                        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


                                      -4-

                                subordinated to the new notes, including any old
                                notes not  exchanged.

                                On September 30, 1999 the notes were effectively
                                subordinated to approximately  $158.0 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
                                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.

                                   The Company

      We are a provider of technologically  advanced fiber optic  communications
infrastructure  and services in North America using our  state-of-the-art  fiber
optic network. We recently have begun providing bandwidth services.

      Our   current  and   targeted   customers   include   new  and   incumbent
telecommunication  providers,  Internet service providers and large corporations
with enterprise network needs.

      We believe that these customers have a limited choice of service providers
capable of offering high-capacity, reliable, secure and cost-effective services.
To meet our customers' demands, we offer a broad range of services on a scalable
basis, including:

     o    bandwidth   services   such  as   optical   channels,   private   line
          transmission,  virtual voice trunking,  Internet  transport,  Internet
          protocol  transport  and  packet-based  data  services,  including  IP
          Transport and Asynchronous Transfer Mode,

     o    network infrastructure such as dark fiber and conduit for sale or
          grant of IRU, and dark fiber and conduit for lease, and

     o    construction services supporting the development of our network.

      We also intend to expand our  business  and network to include  additional
facilities,  including  carrier  hotels that will enable us to provide  services
such as:

     o    applications hosting,

     o    electronic commerce services,

     o    web hosting services,

     o    video transport services,

     o    independent Internet access for transport and peering,

     o    management    services   that   allow   carriers   to   migrate   from
          circuit-switched technologies to packet-based technologies, and

     o    co-location services.

Business Strategy

      To exploit the growing demand for bandwidth,  we have developed a business
strategy to:

     o    provide connectivity to major global population centers,

     o    develop and operate a  technologically  advanced,  high capacity,  low
          cost fiber network,

     o    utilize fiber swaps and strategic relationships to extend the reach of
          our network,

     o    continue to expand our marketing capabilities,


                                      -6-

     o    increase  the number of  products  and  services  that we offer to our
          customers, and

     o    capitalize  on  management  experience  and  relationships  and pursue
          additional strategic alliances.

Recent Developments

Management

         o  Appointment of Chief Executive Officer.  Mr. Gregory Maffei joined
us as Chief  Executive  Officer in January 2000. He was  previously  employed by
Microsoft  Corporation  for  seven  years,  most  recently,  as Chief  Financial
Officer.  Prior to joining us, Mr. Maffei  purchased  equity in Worldwide  Fiber
Inc.  equal to  approximately  8% of our total  equity  outstanding  after  such
purchase on a fully diluted basis. Certain of Mr. Maffei's shares are subject to
repurchase by us in the event his employment ceases.

Network

         o  PSINet. In December 1999 we signed a contract with PSINetworks
Canada Limited and  PSINetworks Co. for fiber optic capacity  between  Vancouver
and Chicago to be  delivered  by the end of March  2000.  In  addition,  we will
provide PSINet with  operation and  maintenance  services at set rates.  Certain
terms of this agreement are subject to finalization.

         o  Europe.  In December 1999 we signed  contracts  with Telia AB(publ),
Telewest  Communications  Group Limited and CARRIER1.  We are swapping  fiber on
part of our North  American  network for fiber on  significant  parts of Telia's
European  network,  which is expected  to be  complete in the fourth  quarter of
2000.  We will  develop  with  Telewest a  multi-conduit  network from London to
Liverpool along diverse routes that pass through seven major population  centers
in England. We expect this network to be complete by the fourth quarter of 2000.
CARRIER1  has agreed to provide us with  wholesale  capacity  from  London to 18
major European  cities,  and an option to swap for dark fiber strands in Germany
and/or wavelengths in France.

                             Summary Financial Data

      The summary  historical  financial data for the year ended March 31, 1996,
the five months ended  August 31,  1996,  the year ended August 31, 1997 and the
nine  months  ended  May 31,  1998 of our  predecessor,  the  telecommunications
division of Ledcor,  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  summary  consolidated
historical  financial  data for the period from February 5, 1998 to 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.  included
elsewhere in this prospectus. The summary consolidated historical financial data
as of and for the periods  ended  September  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 nine  months  ended
September 30, 1999 are derived from the unaudited interim consolidated financial
statements for the nine month period ended September 30, 1999 of Worldwide Fiber
included elsewhere in this Prospectus. Our consolidated financial statements and
the  divisional  financial  statements  of the  predecessor  division  have been
prepared  in  accordance  with U.S.  GAAP.  The  results of  operations  for the
predecessor  division are not comparable to our results of operations  after the
Reorganization.   You  should  read  the   following   information   along  with
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations"  and  the  financial  statements  and  the  related  notes  included
elsewhere in this prospectus.

      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.

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

(1)      Gives pro forma  effect to (1) the  transfer on May 31, 1998 of certain
         of the  operations  of the  predecessor  division and the  Construction
         Services,  Management Services and Employee Services Agreements between
         Worldwide  Fiber and  affiliates of Ledcor,  (2) the  consolidation  of
         WFI-USA as a result of  Worldwide  Fiber's  agreement  to increase  its
         interest  in WFI-USA  from 50% to 75% on  December  31,  1998,  (3) the
         effect of the  interest  expense,  including  amortization  of deferred
         financing  costs,  relating to the  $175,000,000  12 1/2% senior  notes
         issued December 23, 1998 and the  $500,000,000  12% senior notes issued
         July 28,  1999,  and (4) the  amortization  of goodwill  arising on the
         acquisition  of the minority  interest  shares of WFI-CN Fiber Inc. and
         Worldwide Fiber IC LLC.

(2)      Gives  pro  forma  effect  to  (1)  the  interest  expense,   including
         amortization  of deferred  financing  costs,  on the  $500,000,000  12%
         senior notes issued July 28, 1999 and (2) the  amortization of goodwill
         arising on the  acquisition of the minority  interest  shares of WFI-CN
         Fiber Inc. and Worldwide Fiber IC LLC.

(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,
         amortization of goodwill 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),  amortization of goodwill,  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 $74,486,000 and
         pro forma loss for the nine month period ended September 30, 1999 would
         have been insufficient to cover fixed charges by $9,832,000.

(6)      Gives pro forma effect to (1) the issuance of a note  receivable in the
         amount of $77,500,000  provided by the Company to an executive  officer
         of the Company and the  issuance  on  December  22, 1999 of  26,080,000
         Class A Non-Voting  shares and 4,920,000 Class C Multiple Voting Shares
         to the executive  officer for  consideration of $77,500,000 and (2) the
         acquisition  of the minority  interest  shares of WFI-CN Fiber Inc. and
         Worldwide Fiber IC LLC in exchange for Class A Non-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,

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

                                      -11-
<PAGE>

     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 $115  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:

                                                  As of September 30, 1999

Debt to equity ratio.........................           21.9x          5.2x


(1)  Gives pro forma  effect to (1) the  issuance  of a note  receivable  in the
     amount of  $77,500,000  provided by the Company to an executive  officer of
     the Company and the  issuance on December  22, 1999 of  26,080,000  Class A
     Non-Voting  Shares  and  4,920,000  Class  C  Multiple  Voting  Shares  for
     consideration  of  $77,500,000  and (2)  the  acquisition  of the  minority
     interest shares of WFI-CN Fiber Inc. and Worldwide Fiber IC LLC in exchange

      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  $74,486,000  and pro forma loss for the
nine month period ended September 30, 1999 would have been insufficient to cover
fixed charges by $9,832,000.

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,

     o    conditions in the telecommunications industry,

     o    regulatory developments,

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


                                      -12-
<PAGE>

     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  $565,000,000 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.

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



                                      -13-
<PAGE>

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  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-



                                      -14-
<PAGE>

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 continued access to capital markets,

     o    design and engineer fiber networks,

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

     o    acquire additional rights-of-way,

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

                                      -15-
<PAGE>

     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 expect to significantly expand the range of services that
we offer.  This  expansion  includes  providing  various  bandwidth  services to
carriers and other service providers.  We may enter 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 cannot assure you that a market will develop for our
new  services,   that  implementing   these  services  will  be  technically  or
economically  feasible,  that we can successfully develop or market them or that
we can operate and maintain our new services profitably.

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

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 prescribe the terms
and conditions of 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-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


                                      -16-
<PAGE>

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  Experience--We  have little  experience  in the  offering of  bandwidth
services and this could increase our risk of failure.

      We expect an increasing  portion of our revenues to be derived through our
offering of bandwidth and other services.  We have limited  experience  offering
these 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. 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

     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.

                                      -17-
<PAGE>

      The sale or lease of  bandwidth  services  will  require  the  addition of
transmission  equipment to our network.  The network will use a  combination  of
communications   equipment,   software,   operating  protocols  and  proprietary
applications  for the high speed  transportation  of large quantities of digital
signals among multiple locations.  Given the complexity of our network,  digital
signals may become lost or distorted,  which may cause significant losses to our
customers.  The network may also 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.  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 also recently  announced the expansion of our Network into Europe.
We are still evaluating all of the risks associated with these new projects.  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,

                                      -18-
<PAGE>


     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  our  international  plans,   including  our
expansion into Europe, 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,
including  optical  equipment.  Recently,  some  companies  have  experienced  a
shortage of fiber optic cable.  We cannot ensure you that we will not experience
such a shortage.  We are also dependent on Nortel Networks,  Newbridge  Networks
and Marconi plc for the  transmission  equipment we 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 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."

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  approximately  90% 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."

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



                                      -21-
<PAGE>

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.  The Federal  Communications  Commission  has held that
telecommunications and common carrier services are essentially the same. 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.  We cannot assure you that the
cost of compliance with these various  programs will not have a material adverse
effect upon our results of operations and financial condition and our ability to
meet our obligations 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

                                      -22-
<PAGE>

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 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 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



                                      -23-
<PAGE>

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.  Bell Atlantic  received such  authorization  for New York in
December  1999.  It is  anticipated  that  additional  Regional  Bell  Operating
Companies  may  receive  authorization  in some  states  to  provide  inter-LATA
telecommunications  during  2000.  Such  authority  if  granted  could  increase
competition from Regional Bell Operating  Companies in providing fiber and fiber
services, which could adversely affect our business operations.

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

      The 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

                                      -24-
<PAGE>

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
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  telecommunications  common
carrier in Canada 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.

      International Traffic

      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

      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.  Although  this public notice  proceeding is not yet closed,  some
parties in the proceeding have advocated that the current contribution regime be
converted into 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 Proceedings

      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,
interim  basis,  until  the  Canadian  Radio-television  and  Telecommunications
Com-

                                      -26-

mission  has made a  determination  on the  appropriate  terms,  conditions  and
compensation  that  should  be  payable  to the  City  for the use of  municipal
property. In a ruling issued on October 27, 1999, the  Canadian-Radio-television
and  Telecommunications  Commission  granted  the City's  request for an interim
order  directing each of the carriers that obtained  indefeasible  rights-of-use
from us to pay the City  $1.00  for the  right to access  the  City's  municipal
property  during the period of time  before  the  Canadian-Radio-television  and
Telecommunications  Commission makes a determination for the appropriate  terms,
conditions  and  compensation  that should be payable to the City for the use of
municipal  property.  On December  3, 1999,  the  Canadian-Radio-television  and
Telecommunications  Commission  issued a public notice which invited  interested
parties  to  comment  on what the terms  and  conditions  of access by  Canadian
carriers  to  municipal  property  in  Vancouver  should be for the  purposes of
constructing,  maintaining and operating  transmission lines. We anticipate that
the  Canadian-Radio-television  and Telecommunications  Commission will render a
decision  on our March 19,  1999  application  against the City at the same time
that  it  renders  a  decision  on  the  matters  raised  by its  public  notice
proceeding.  Failure  to obtain  the  orders we have  requested  in our  initial
application to that Canadian Radio-television and Telecommunications  Commission
could have a material  adverse effect on our business,  financial  condition and
results of operations.

      We have operations  based in Canada and anticipate  operations in Ireland,
France and other  foreign  jurisdictions.  We are  exposed to risks  inherent in
international operations, including the following:

     o    general economic, social and political conditions

     o    the  difficulty of enforcing  agreements  and  collecting  receivables
          through certain foreign legal systems

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

     o    required compliance with a variety of foreign laws and regulations

     o    changes in United  States  laws and  regulations  relating  to foreign
          trade and investment

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 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


                                      -27-
<PAGE>

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 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.

          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.

(1)  Gives pro forma  effect to (1) the  transfer  on May 31, 1998 of certain of
     the operations of the predecessor  division and the Construction  Services,
     Management  Services and Employee  Services  Agreements  between  Worldwide
     Fiber and  affiliates  of  Ledcor,  (2) the  consolidation  of WFI-USA as a
     result of Worldwide  Fiber's  agreement to increase its interest in WFI-USA
     from 50% to 75% on  December  31,  1998,  (3) the  effect  of the  interest
     expense,  including  amortization of deferred financing costs,  relating to
     the  $175,000,000  12 1/2% senior  notes  issued  December 23, 1998 and the
     $500,000,000   12%  senior  notes  issued  July  28,  1999,   and  (4)  the
     amortization  of  goodwill  arising  on the  acquisition  of  the  minority
     interest shares of WFI-CN Fiber Inc. and Worldwide Fiber IC LLC.

(2)  Gives pro forma effect to (1) the interest expense,  including amortization
     of deferred  financing  costs, on the  $500,000,000 12% senior notes issued
     July  28,  1999  and  (2)  the  amortization  of  goodwill  arising  on the
     acquisition  of the  minority  interest  shares of WFI-CN  Fiber  Inc.  and
     Worldwide Fiber IC LLC.

(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,  amortization
     of  goodwill  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),  amortization  of  goodwill,  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 $74,486,000 and pro forma loss
     for the nine  month  period  ended  September  30,  1999  would  have  been
     insufficient to cover fixed charges by $9,832,000.

(6)  Gives pro forma  effect to (1) the  issuance  of a note  receivable  in the
     amount of  $77,500,000  provided by the Company to an executive  officer of
     the Company and the  issuance on December  22, 1999 of  26,080,000  Class A
     Non-Voting  shares  and  4,920,000  Class C Multiple  Voting  Shares to the
     executive  officer for consideration of $77,500,000 and (2) the acquisition

                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.

      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").  On September  27, 1999, we acquired  additional  fiber
optic  network  assets from  Ledcor.  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 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.  Since January 1, 1999, the impact
of  the  Construction  Services  Agreement  has  not  been  significant  on  our
consolidated financial statements.

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

      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.

      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.

Joint Ventures

      Our consolidated balance sheet at September 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  September 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   dark   fiber   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 our network on both  railroads' ROW in
Canada  and  the  United  States.  See   "Business--Description  of  IC  and  CN
Agreements."

      We are  currently in  negotiations  to acquire the  minority  interests in
WFI-USA and in two joint ventures related to the IC and CN ROW.

Results of Operations

Worldwide Fiber Inc.
     Nine Months Ended  September  30, 1999 and the period from February 5, 1998
to September 30, 1998 (operations commenced June 1, 1998)

      Revenue  for  the  nine  month  period  ended   September   30,  1999  was
$235,138,100,  versus  $104,819,000  for the four month period from June 1, 1998
(commencement  of  operations)  to September  30,  1998.  Revenue in the current
period was primarily derived from sales of conduit and fiber optic strands along
segments in the Pacific Northwest, northeast U.S. and eastern Canada.

      Costs were  $165,263,000  (69% of revenue) for the nine month period ended
September 30, 1999, versus $90,909,000 (87% of revenue) for the period from June
1, 1998  (commencement  of operations) to September 30, 1998.  These reflect the
costs  incurred in  development  of our network  which  include costs related to
subcontractors, rights-of-way and equipment purchases.

      Gross  profit for the nine  month  period  ended  September  30,  1999 was
$69,875,000 (30% of revenue), versus $13,910,000 (13% of revenue) for the period
from June 1, 1998  (commencement  of  operations)  to September 30, 1998.  These
increases are due to the higher margins achieved in ownership and development of
dark fiber networks, compared to construction services.

      General and  administrative  expenses were $17,263,000 (5% of revenue) for
the nine months ended September 30, 1999,  versus $1,318,000 (1% of revenue) for
the period from June 1, 1998 (commencement of operations) to September 30, 1998.
We have  completed a majority of the tasks  necessary to perform the  transition
from Ledcor's management  information and accounting systems to our own. General
and  administrative  expenses are expected to continue to increase as we develop
our systems,  hire  additional  personnel and  implement our bandwidth  services
strategy.

                                      -35-
<PAGE>

      Interest  expense was  $20,468,000 for the nine months ended September 30,
1999 and was  principally  due to the issue of senior notes in December 1998 and
July 1999. Interest income totaled $8,020,000 for this period and arose from the
investment of the proceeds of the senior notes in short-term,  investment  grade
securities.

      Income taxes  provided for the nine month period ended  September 30, 1999
totaled  $20,175,000,  versus  $5,402,000  for the  period  from  June  1,  1998
(commencement of operations) to September 30, 1998.  These consist  primarily of
current taxes arising from our U.S. and Canadian operations.

      Minority  interest  for the nine month  period  ended  September  30, 1999
totaled $5,747,000 and represents 25% of WFI-USA's and CN/IC's net income.

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 dif-

                                      -36-
<PAGE>

erence 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 September 30, 1999, we had working  capital of $816 million,  including
$675 million in cash or cash  equivalents.  Cash used in  operations  during the
nine months ended September 30, 1999 totaled $139 million.

      We  have an  aggressive  business  plan to  build  out  our  network.  Our
currently planned network will provide us with 37,800 total route miles and span
two  continents,  and we intend to further expand this network to provide global
connectivity.  Building out the network 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  equipment  to  establish
transmission  facilities.  We  anticipate  that we will  continue to  experience
negative  cash flow  (after  capital  expenditures)  as we build out the network
which is expected to be completed in the first quarter of 2001.

      We estimate  that the total cost of building and  lighting  our  currently
planned network will be approximately $2.8 billion. Such costs are:

     o    We estimate  that the total cost to build out and light our network in
          North America will be approximately $1.6 billion.

     o    We estimate  that the total cost to build out and light our network in
          Europe will be $320  million.  In addition to the sources of funds set
          forth  below,  in order to  expeditiously  build  out our  network  in
          Europe, we recently signed an agreement with Telia under which we will
          swap multiple fiber strands on part of our North  American  network in
          exchange for an IRU for approximately  4,000 miles on Telia's European
          network.

     o    We estimate the total cost of the Hibernia  undersea  cable project to
          be approximately $865 million.

         In order to finance our network development:

     o    We have  issued  $675  million  of  senior  notes and plan to issue an
          additional one billion dollars in the first half of 2000.

     o    We intend to make a public  offering of our Class A Non-Voting  Shares
          in the first half of 2000.

     o    We intend to consummate the $565 million Hibernia credit facility. The
          credit  facility  is being  provided on a project  finance  basis to a
          group of our subsidiaries and is non-recourse to us.

     o    We have issued $345 million of our Series A Non-Voting Preferred Stock
          to a number of private equity investors.  A significant portion of the
          proceeds  from this  issuance  will  fund the  equity  portion  of the
          Hibernia project.

      We anticipate  that these funding  sources will provide us with sufficient
capital to complete our  terrestrial  and undersea  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 which are beyond our control,  including changes in
the competitive  environment of our current and planned markets,  we expect that
our actual costs may vary materially from those currently budgeted. In the event
that our actual costs  exceed our current  budget or we do not have the funds we
anticipate,  we have the ability to adjust the number or sequence of segments we
develop.

      We 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 serv-

ces strategy,  the Hibernia project or for other opportunities on a timely basis
or on terms that are acceptable to us, or at all.

Accounting Pronouncements

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

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

      In June 1999,  the  Financial  Accounting  Standards  Board (FASB)  issued
Interpretation  No. 43, "Real Estate Sales, an  interpretation of FASB Statement
No. 66." The  interpretation is effective for sales of real estate with property
improvements or integral  equipment entered into after June 30, 1999. Under this
interpretation,  after June 30, 1999,  title must  transfer to a lessee in order
for a lease transaction to be accounted for as a sales-type lease.  Transactions
will be accounted for as operating  leases where title is not transferred to the
lessee or if the agreement was entered into after June 30, 1999.

Market Risk Disclosures

      Interest Rate Risk

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

      The senior notes are  comprised of  $175,000,000  12.5% notes due December
15, 2005 with interest paid quarterly and $500,000,000 12.0% notes due August 1,
2009 with interest paid quarterly.  These senior notes have provisions which may
permit or obligate  the Company to redeem all or part of the notes  before their
redemption dates.

      Foreign Currency Risk

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

                                    BUSINESS

General

      We are a provider of technologically  advanced fiber optic  communications
infrastructure  and services in North America using our  state-of-the-art  fiber
optic  network.  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 currently  planned network will provide us with 35,400 route miles and
span two  continents  and we intend to further  expand  this  network to provide
global  connectivity.  Our network will consist of fiber optic strands installed
in protective  conduit buried along diverse  rights-of-way  and strands acquired
from other  developers and carriers  through swaps,  and related  infrastructure
such as regeneration shelters. We plan to further develop and expand our network
to meet customer needs.  Our network is expected to cover  approximately  24,000
route miles in North America and encompass both long haul and  intra-city  route
miles  (comprising in excess of 1,000,000 fiber miles) and provide  connectivity
between  approximately  50 major  population  centers.  Our network in Europe is
currently  expected  to cover  approximately  6,200 route  miles  (assuming  the
exercise of our CARRIER1  option) on a long-haul basis between  approximately 20
major  population  centers.  We also  intend to further  develop  and expand our
network  in  Europe.  Our  7,600  mile  Trans-Atlantic   cable  will  utilize  a
high-speed,  high-capacity,  self-healing  ring that currently  connects landing
sites in Boston, Halifax, Dublin and Liverpool to serve the continuing growth of
demand for  bandwidth  in the  Trans-Atlantic  market.  In addition to continued
expansion  to  other  North  American  and  European  cities,  we are  reviewing
opportunities  to expand the  geographic  reach of our network to encompass Asia
and Latin America.

      We believe that these customers have a limited choice of service providers
capable of offering high-capacity, reliable, secure and cost-effective services.
To meet our customers' demands, we offer a broad range of services on a scalable
basis,  including  bandwidth  services,  such as optical channels,  private line
transmission,  virtual voice tracking,  Internet transport, IP transport, packet
switch   services,   including   MPLS,   IP  and  ATM.  We  also  offer  network
infrastructure, such as dark fiber and conduit for sale, lease or IRU.

      We also intend to expand our business to include  carrier hotels that will
enable us to provide services such as:

o    applications hosting,

o    electronic commerce services,

o    web hosting services,

o    video transport services,

o    independent Internet access for transport and peeving.

o    management  services that allow  carriers to migrate from  circuit-switched
     technologies to packet-based technologies, and

                                      -40-
<PAGE>

o    co-location services.

      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 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  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

                                      -41-
<PAGE>

     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:

     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.

      In  addition  to further  North  American  development  and our  announced
transatlantic  fiber optic cable  project and European  network  assets,  future
network  development  locations  could  include  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.

      For Hibernia we have applied for licenses with the  governing  authorities
in each of  Ireland,  Canada,  the United  Kingdom  and the United  States.  The
licenses have been granted in Ireland, the United Kingdom and the United States.
One  license  for which we  applied  in Canada  has been  approved  and a second
license  application in

                                      -42-
<PAGE>

Canada is pending. We also applied for various permits and consents for Hibernia
in Ireland, Canada, the United Kingdom and the United States.  Approximately 40%
of these  permits  and  consents  have been  granted and the  remaining  60% are
pending.  While there can be no assurance that the remaining  licenses,  permits
and consents will be granted, we do not anticipate any problems at this time.

      In June  1999,  we  entered  into a  turnkey  supply  agreement  with Tyco
Submarine  Systems  Ltd.  ("Tyco")  whereby  Tyco  will  serve  as  the  primary
contractor for Hibernia.  The contract price is approximately $634 million.  The
Company has paid over $100 million in advance payments to Tyco. Tyco is required
to deliver Hibernia in the first quarter of 2001.

      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.

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.

     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:

          o    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,

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

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

          o    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.

                                      -43-
<PAGE>

     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:

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

          o    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 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 currently planned network will cover approximately  37,800 route miles
and will encompass  long-haul and  intra-city  routes and  Trans-Atlantic  fiber
optic  cable.  Our  network  will  consist of fiber optic  assets  which we have
installed  along diverse  rights-of-way  or acquired from other  developers  and
carriers  through swaps.  We plan to further  develop and expand our network and
its reach in response to customer demand.

North America

      Our North American network is expected to cover approximately 24,000 route
miles and encompass  both long-haul and  intra-city  route miles  (comprising in
excess of  1,000,000  fiber  miles) by the first  quarter of 2001.  We intend to
further  develop,  swap or purchase  additional  long haul route miles and intra
city rings in North America. The footprint will consist of the following:

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

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

Undersea Cable

      Our 7,600 route mile  Trans-Atlantic  cable project utilizes a high-speed,
high-capacity,  self-healing  ring design  that will  connect  landing  sites in
Boston,  Halifax,  Dublin and Liverpool to serve the continuing growth of demand
for bandwidth in the  Trans-Atlantic  market.  In June,  1999, we entered into a
supply agreement with Tyco

                                      -44-
<PAGE>

whereby  Tyco  will  serve  as  the  primary  contractor  for  Hibernia,  taking
responsibility  for the design,  construction,  installation  and testing of the
cable.  Tyco is a  leading  supplier  of  undersea  communications  systems  and
services to various  projects  around the world.  Hibernia's  self-healing  ring
design will have a capacity of 1.92  Terabits per second on each segment using 4
fiber pair with state-of-the-art,  48-wave length technology on each fiber pair.
Tyco is required to complete the  construction  of Hibernia by the first quarter
of 2001.

Europe

      Our network in Europe is currently expected to cover  approximately  6,200
route miles (assuming the exercise of our CARRIER1 option) linking approximately
20 European cities by the first quarter of 2001.

      The fiber we acquired via the  Telewest,  Telia and CARRIER1  transactions
places our assets in seven European  countries.  The current  planned  footprint
will consist of the following five rings:

          o    Liverpool,  Manchester,  Birmingham,  Bristol, London, Cambridge,
               Sheffield, Liverpool

          o    London,  Paris,  Strasbourg,   Frankfurt,   Dusseldorf,  Hamburg,
               Amsterdam, London

          o    Hamburg, Kolding, Copenhagen, Hamburg

          o    Copenhagen, Stockholm, Oslo, Copenhagen

          o    Frankfurt,  Stuttgart, Munich, Dresden, Berlin, Hamburg, Cologne,
               Frankfurt

      These routes were acquired through the following agreements:

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

          o    Telia.  In December  1999,  we signed a contract with Telia under
               which we will swap for a  twenty-year  period an IRU for multiple
               fiber strands on part of our North  American  network in exchange
               for an IRU for approximately  4,000 route miles of multiple fiber
               strands of Telia's European network covering Germany, France, the
               United Kingdom, the Netherlands,  Denmark,  Sweden and Norway. We
               will deliver  fibers to Telia by the end of the first  quarter of
               2001 and Telia  will  deliver  the fibers to us by the end of the
               fourth  quarter of 2000.  In addition,  Telia and we will provide
               each other with co-location services,  regeneration sites, points
               of  presence  in  main  cities  and  operations  and  maintenance
               activities.

          o    CARRIER1.  In December  1999,  we signed a contract with CARRIER1
               under  which we have the option to order  wholesale  capacity  on
               their network connecting London to 18 European cities. The option
               provides  us  with  wholesale   capacity  on  CARRIER1's  network
               beginning  March 1, 2001. In addition,  the contract  provides us
               with the  option to  acquire  multiple  strands  in  Germany  and
               wavelength channels in France.

Future Network Development

      We believe that there may be further  opportunities  in North  America and
Europe to continue the type of network  development we are currently  deploying.
In addition to continued  expansion to other North American



                                      -45-
<PAGE>

and European  cities,  we are reviewing  opportunities  to expand the geographic
reach of our network to encompass Asia and Latin America.  We believe that these
further developments will enhance the connectivity and value of our network.

Network Development Plan

      We expect to complete the development of our Network in 2001. Although the
following  tables  summarize our current plans for  completing  the  terrestrial
network in North  America  and  Europe and  Hibernia,  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:

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 transmit 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.

                                      -47-
<PAGE>

      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,

          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") is the human  service  connection
between  our  customers  and  the  technology  that  ultimately  delivers  their
services. We have completed construction of our NOC in Vancouver,

                                      -48-
<PAGE>

which  operates  24  hours a day,  365  days a year.  We are in the  process  of
designing our NOC in Dublin.  Our Dublin NOC will be primarily  responsible  for
European  operations and is scheduled to be on line in October 2000. Each of the
NOCs will serve as a back up to the other. In addition,  Nortel will continue to
provide redundant network services to us through June 2000.

      In addition  to the two main NOCs in  Vancouver  and  Dublin,  we are also
designing  support centers in Denver to maintain cable operations and in Halifax
to maintain  the  Hibernia  cable.  The NOCs 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.

                                      -49-
<PAGE>

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 tunnels  underneath the river or  obstruction  and feed
the conduit through the tunnel.

      After the conduit has been buried (or attached to a bridge or tunnel), and
as a segment  nears  completion,  the fiber optic cable is installed or "jetted"
through the conduit. 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.

                                      -50-
<PAGE>

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 Agreements." 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

                                      -51-
<PAGE>

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.  The services we 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  its own
switching and routing  equipment and will have the choice of installing  its own
protection  equipment or use optical protection supplied as part of our service.
We offer the following services:

          o    transparent OC-48 and OC-192 under IRU or lease,

          o    optical ring protection, and

          o    linear routes available, add/drop along route.

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

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

          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 offer  customers
variable  capacity across our network to connect multiple service locations into
a single "Virtual  Network"  specific for each customer.  Specific  packet-based
services include ATM and IP transport.

      ATM service includes 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 includes the following service attributes:

                                      -52-
<PAGE>

          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.

      We are in the process of building our European and Hibernia sales teams.

      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,


                                      -53-
<PAGE>

          o    ISPs,

          o    long distance companies (North American and international),

          o    RBOCs,

          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
more than 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.

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.

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

Competition

      Fiber optic  systems  are  currently  under  construction  or  development
throughout North America and Europe.  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  sup-

                                      -54-
<PAGE>

pliers 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 in North America
and Europe will come from the above  companies as well as other  incumbents.  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.

      Our undersea cable will compete with existing and announced trans-Atlantic
cable systems, including a global network recently announced by Tyco.

      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 December 31, 1999,  we employed  approximately  1,000  full-time and
seasonal  people.  Depending  upon the  level  of  development  or  construction
activity, we will increase or decrease our work force. Generally, non-management
employees from Canada are covered by a collective  bargaining agreement with the
Christian  Labor  Association of Contractors  which expires on February 28, 2001
and is  automatically  renewable  unless  either  party gives prior  notice.  We
believe  that our work  force  is  highly  capable  and  motivated  and that our
relations with our employees are good. In connection with the  construction  and
maintenance of our fiber optic networks,  we may use third-party  contractors to
meet  excess  demand and harness  local  construction  knowledge,  some of whose
employees may be represented by other unions or covered by collective bargaining
agreements.

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 our Vancouver  offices to us under agreements that expire in
2002.  Ledcor  also  leases our  facilities  in Toronto to us. We lease space in
Denver  under a short  term lease  with a third  party.  The office of our Chief
Executive Officer is in Seattle,  Washington. We also currently lease offices or
property in several other states or provinces.

Legal Proceedings

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

                                      -55-

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, through December 31, 1999, paid 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.



                                      -59-
<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.

     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



                                      -60-

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.



                                      -62-
<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.
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.

     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



                                      -63-
<PAGE>

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.

     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
sub-



                                      -64-
<PAGE>

scriber's name, telephone number, and address, if that information is published
or accepted for publication in any directory format. Under the FCC's rules, a
carrier may only use a customer's proprietary network information to market a
service that is "necessary to, or used in," the provision of a service that the
carrier already provides to the customer, unless it receives the customer's
prior oral or written consent to use that information to market other services.
The Court of Appeals for the Tenth Circuit recently invalidated the FCC's rules
with respect to how a carrier must obtain customer authorization for the use of
customer proprietary network information. The FCC is expected to further
challenge this court decision. In addition, the FCC recently relaxed a number of
the requirements it originally adopted, which gives some flexibility to carriers
on how to comply with these rules. These rules, either as adopted or as
modified, may impede our ability to effectively market integrated packages of
services and to expand existing customers' use of our services.

     Universal Service. On May 8, 1997, the FCC released an order establishing a
significantly expanded federal universal service subsidy regime. For example,
the FCC established new subsidies for telecommunications and certain information
services provided to qualifying schools and libraries and for services provided
to rural health care providers. The FCC also expanded or revised the federal
subsidies for local exchange telephony services provided to low-income consumers
and consumers in high-cost areas. Providers of interstate telecommunications
services, as well as certain other entities, such as private carriers offering
excess capacity to end user customers, must pay for these programs. Our share of
these federal subsidy funds would be calculated based on end-user revenues. The
schools and libraries and rural health care support mechanisms are assessed
against interstate, international, and intrastate end-user revenues. Currently,
the FCC is calculating assessments based on the prior year's revenues and has
recently increased the size of the schools and libraries fund by 50 percent.
Assuming that the FCC continues to calculate contributions based on the prior
year's revenues, we believe that we will not be liable for subsidy payments in
any material amount during 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. 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 lo-



                                      -65-
<PAGE>

cated 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.

     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-



                                      -66-
<PAGE>

     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.

     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


                                      -67-
<PAGE>

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. Bell Atlantic in New York received
such approval in December 1999. RBOCs are reported to have made substantial
progress in achieving compliance with the requirements for such approvals and
one or more RBOCs may receive inter-LATA approval in some states within the next
year. 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 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 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. At present, we, through various subsidiaries, have
tariffs on file with , and/or has obtained various certificates of operating
authority from, approximately 25 states that were necessary under state laws to
gain authorizations needed to operate as a carrier or to construct fiber
facilities in those states, even though a company does not operate as a common
carrier. Those tariffs provide that prices, terms and conditions of an offering
will be set based upon individual determinations for each customer. These
tariffs may be subject to challenge, but usually are not. None of our tariffs
has been changed to date. Various state regulators may attempt to regulate the
Company's rates or practices, but generally, state regulators do not actively
regulate the offerings of non-dominant carriers such as us.

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

     Local

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

Canada

     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. 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. In providing dark or lit fiber on a leased basis, we are
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.

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



                                      -70-
<PAGE>

     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.

     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 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.

     International Traffic

     On October 1, 1998, the CRTC issued Telecom Decision CRTC 98-17 ("Decision
98-17") which established a framework for competition in Canada's international
telecommunications services market to coincide with the Government of Canada's
decision to terminate the monopoly of Teleglobe Canada Inc. over
telecommunications facilities linking Canada to overseas destinations. In that
decision, the CRTC determined that a party acquiring an IRU interest in an
international submarine cable would not necessarily fall within the definition
of a 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 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.

     CRTC Proceedings

     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,
interim basis, until the Canadian Radio-television and Telecommunications
Commission has made a determination on the appropriate terms, conditions and
compensation that should be payable to the City for the use of municipal
property. In a ruling issued on October 27, 1999, the Canadian-Radio-television
and Telecommunications Commission granted the City's request for an interim
order directing each of the carriers that obtained indefeasible rights-of-use
from us to pay the City $1.00 for the right to access the City's municipal
property during the period of time before the Canadian-Radio-television and
Telecommunications Commission makes a determination for the appropriate terms,
conditions and compensation that should be payable to the City for the use of
municipal property. On December 3, 1999, the Canadian-Radio-television and
Telecommunications Commission issued a public notice which invited interested
parties to comment on what the terms and conditions of access by Canadian
carriers to municipal property in Vancouver should be for the purposes of
constructing, maintaining and operating transmission lines. We anticipate that
the Canadian-Radio-television and Telecommunications Commission will render a
decision on our March 19, 1999 application against the City at the same time
that it renders a decision on the matters raised by its public notice
proceeding. Failure to obtain the orders we have requested in our initial
application to that Canadian Radio-television and Telecommunications Commission
could have a material adverse effect on our business, financial condition and
results of operations.

                        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.



                                      -73-
<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. We are currently in negotiations to acquire the minority interest in
WFI-USA in exchange for the issue of our Shares. We are currently in
negotiations to acquire the minority interests of CN and IC in exchange for the
issue of our Shares.

     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. Further-



                                      -75-

more, 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



                                      -77-
<PAGE>

          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.

     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). Specifically, in order for holders of the
Series A Non-Voting Preferred Shares to convert their shares into voting shares,
there must have been either a public offering of voting shares by us or our
shareholders having gross proceeds of at least $150 million, we must have issued
or distributed any additional voting shares (with certain exceptions) or there
must have been an elimination of the restrictions on ownership of voting shares
and on the control in fact of the Company by non-Canadians under the
Telecommunications Act (Canada) and the rules and regulations promulgated
thereunder. These actions are not in the control of the holders of the Series A
Non-Voting Preferred shares, nor do we contemplate or anticipate these actions
within the next 60 days. 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.

     The Shareholders Agreement specifically restricts the ability of the
holders of the Series A Preferred Shares to convert their shares into voting
shares. See "--Attributes of the Series A Non-Voting Preferred Shares."

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 18 directors. Messrs. Creamer, Garvey,
Gheewalla and Rush were nominated pursuant to this provision.



                                      -78-
<PAGE>

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 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.

Mr. Maffei

     On December 22, 1999, Gregory Maffei purchased 26,080,000 of our Class A
Non-Voting Shares and 4,920,000 of our Class C Multiple-Voting Shares for $77.5
million. To facilitate the sale, we advanced an amount equal to the purchase
price to Mr. Maffei under a limited recourse note maturing on December 22, 2005.
The note will mature, in whole or in part, as a result of the sale of our shares
by Mr. Maffei or Mr. Maffei's ceasing to be employed by us.

     We have the right to repurchase certain of Mr. Maffei's shares at the
original purchase price plus the pro rata amount of interest accrued on the note
in the event Mr. Maffei's employment with us is terminated before June 30, 2003.
In addition, Mr. Maffei has the right to require us to repurchase some or all of
his shares not subject to our repurchase right.

     Mr. Maffei became our Chief Executive Officer effective January 18, 2000.
Mr. Maffei is entitled to nominate two Directors to our Board.

                               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 , 2000; 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 , 2000, 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.

     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 (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 instru-



                                      -81-
<PAGE>

ment 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 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



                                      -82-
<PAGE>

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.

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



                                      -83-
<PAGE>

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.

     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.



                                      -84-

     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 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
deliv-



                                      -85-
<PAGE>

ery 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.

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.



                                      -86-
<PAGE>

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."



                                      -88-
<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.

     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



                                      -89-
<PAGE>

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

(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"):



                                      -90-
<PAGE>

(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

(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 unpur-



                                      -91-
<PAGE>

chased 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:

(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



                                      -92-
<PAGE>

(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 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:



                                      -93-
<PAGE>

(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

     Restricted Payments

     Worldwide Fiber will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly:

(1)  declare or pay any dividend or make any other payment or distribution on
     account of Worldwide Fiber's or any of its Restricted Subsidiaries' Equity
     Interests, including, without limitation, any payment in connection with
     any merger or consolidation involving Worldwide Fiber or any of its
     Restricted Subsidiaries, or to the direct or indirect holders of Worldwide
     Fiber's or any of its Restricted Subsidiaries' Equity Interests in their
     capacity, other than dividends or distributions payable in Equity Interests
     (other than Disqualified Stock) of Worldwide Fiber or to Worldwide Fiber or
     a Restricted Subsidiary of Worldwide Fiber;

(2)  purchase, redeem or otherwise acquire or retire for value, including,
     without limitation, in connection with any merger or consolidation
     involving Worldwide Fiber, any Equity Interests of Worldwide Fiber or any

     of Worldwide Fiber, other than the Equity Interests owned by Worldwide
     Fiber or any Restricted Subsidiary of Worldwide Fiber;

(3)  make any payment on or concerning, 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 of the notes; or

(4)  make any Restricted Investment (all of these payments and other actions
     described in clauses (1) through (4) above being collectively referred to
     as "Restricted Payments"),

unless:

(1)  at the time of and after giving effect to the Restricted Payment, no
     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
     giving pro forma effect to the Restricted Payment as if the Restricted
     Payment had been made at the beginning of the applicable four-quarter
     period, have been permitted to incur at least $1.00 of additional
     Indebtedness under clause (1) or (2) of the first paragraph of the covenant
     described below under the caption "--Incurrence of Indebtedness and
     Issuance of Preferred Stock"; and



                                      -94-
<PAGE>

(3)  such Restricted Payment, together with the aggregate amount of all other
     Restricted Payments made by Worldwide Fiber and its Restricted Subsidiaries
     after the Issue Date, excluding Restricted Payments permitted by clauses
     (2), (3), (4), (6), (7), (8)(a), (9), (10), (11), (12) and (13), is less
     than the sum, without duplication, of

     (a)  50% of the Consolidated Net Income of Worldwide Fiber 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 Worldwide
          Fiber's most recently ended fiscal quarter for which internal
          financial statements are available at the time of the Restricted
          Payment, or, if the Consolidated Net Income for the period is a
          deficit, less 100% of the deficit, plus

     (b)  100% of the aggregate net cash proceeds received by Worldwide Fiber
          since the Issue Date as a contribution to its common equity capital or
          from the issue or sale of Equity Interests of Worldwide Fiber, other
          than Disqualified Stock, or from the issue or sale of convertible or
          exchangeable Disqualified Stock or convertible or exchangeable debt
          securities of Worldwide Fiber that have been converted into or
          exchanged for the Equity Interests, other than Equity Interests, or
          Disqualified Stock or debt securities, sold to a Subsidiary of
          Worldwide Fiber, plus the aggregate net cash proceeds received by
          Worldwide Fiber upon the conversion or exchange, plus

     (c)  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 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"),
          not to exceed in the case of any Person the amount of Restricted
          Investments previously made by Worldwide Fiber or any of its
          Restricted Subsidiaries in the Unrestricted Subsidiary (after the
          Issue Date) and in each case which was treated as a Restricted Payment
          (other than the Restricted Payment that was made under the provisions
          of paragraphs (1) through (13) below).

     The preceding provisions will not prohibit:

(1)  the payment of any dividend within 60 days after the date it is declared,
     if at the date of declaration the payment would have complied with the
     provisions of the indenture;

(2)  the redemption, repurchase, retirement, defeasance or other acquisition of
     any subordinated Indebtedness of Worldwide Fiber or of any Equity Interests

     Subsidiary of Worldwide Fiber) of, Equity Interests of Worldwide Fiber
     (other than Disqualified Stock); provided that the amount of the net cash
     proceeds that are utilized for the redemption, repurchase, retirement,
     defeasance or other acquisition 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
     incurrence of Permitted Refinancing Indebtedness; provided that the amount
     of the net cash proceeds that are so utilized shall be excluded from clause
     (3)(b) of the preceding paragraph;

(4)  Investments made out of the net cash proceeds of a substantially concurrent
     issue and sale (other than to a Subsidiary of Worldwide Fiber) of Equity
     Interests (other than Disqualified Stock) of Worldwide Fiber; provided that

     proceeds from any issuance during the calendar year of Equity Interests by
     Worldwide Fiber to employees, officers or directors of Worldwide Fiber and

     directors of Worldwide Fiber or its Restricted Subsidiaries which proceeds
     are used to purchase Equity Interests of Worldwide Fiber held by the
     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
     Stock of the Person;

(7)  Permitted Fiber Investments in Telecommunications Assets;

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

(9)  Investments the payment for which consists exclusively of Equity Interests
     (other than Disqualified Stock) of Worldwide Fiber;

     fiscal quarter preceding the date of such Investment;

(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

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



                                      -96-
<PAGE>

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"):

(1)  the incurrence by Worldwide Fiber 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
     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";

(2)  the incurrence by Worldwide Fiber and its Restricted Subsidiaries of
     Existing Indebtedness;

(3)  the incurrence by Worldwide Fiber of Indebtedness represented by the notes
     and the Series B Notes;

(4)  the incurrence by Worldwide Fiber 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 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, develop-

     ment, 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
     intercompany Indebtedness) that was permitted by the indenture to be
     incurred under the first paragraph of this covenant or clauses (2), (3),
     (4), (12), (14), (15) or (16) of this paragraph;

(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
     Hedging Obligations that are incurred for 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 the Hedging Obligation does not exceed the amount of
     Indebtedness or other liability to which the Hedging Obligation relates;

(8)  the guarantee by Worldwide Fiber or any of its Restricted Subsidiaries of
     Indebtedness of Worldwide Fiber or any Restricted Subsidiary of Worldwide
     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;



                                      -98-
<PAGE>

(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
     time outstanding;

(15) Indebtedness of Worldwide Fiber not to exceed, at any one time outstanding,
     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 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
     with respect to any other interest or participation in, or measured by, its
     profits, or pay any indebtedness owed to Worldwide Fiber or any of

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

     in the notes;

(3)  applicable law;

(4)  any instrument governing Indebtedness or Capital Stock of a Person acquired
     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;

     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;



                                     -100-
<PAGE>

(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

     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
is the surviving corporation); or (2) 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:

(1)  either: (a) Worldwide Fiber is the surviving corporation; or (b) the Person
     formed by or surviving the amalgamation, consolidation or merger (if other
     than Worldwide Fiber) or to which the 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 of Canada or
     the United States, any state of the United States or the District of
     Columbia;

(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;



                                     -101-
<PAGE>

(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
substantially 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



                                     -102-
<PAGE>

          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 re-



                                     -103-
<PAGE>

sulted 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.

     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;



                                     -104-
<PAGE>

(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;

(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.



                                     -105-
<PAGE>

     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 indenture 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:



                                     -106-
<PAGE>

(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 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

     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 obligation 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;



                                     -108-
<PAGE>

(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;

(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.



                                     -109-
<PAGE>

     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
          fed-



                                     -110-
<PAGE>

          eral 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 the 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 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
federal or state securities laws in any federal or state court located in the
Borough of Manhattan in The City of New York, and submits to the non-exclusive
jurisdiction.

                        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,

     o    pay dividends on stock or repurchase stock,



                                     -127-
<PAGE>

     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. We expect the facility to close in the first
quarter of 2000.

     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.

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



                                     -128-
<PAGE>

definitive documentation, up to $565 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.





                                     -129-
<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."



                                     -130-
<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.

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.



                                     -133-
<PAGE>

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.

     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.



                                     -134-
<PAGE>

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 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 re-



                                     -135-
<PAGE>

lated 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 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."



                                     -136-
<PAGE>

     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
inverse of the noon buying rate in New York City for cable transfers in foreign
currencies, as certified for customs purposes by the Federal Reserve Bank of New
York, the average of these exchange rates on the last day of each month during
this period, and the exchange rate at the end of this period:

Asynchronous Transfer Mode
(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

                                    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.......................      A provider of communications transmission services by fiber, wire or radio.
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.
CLEC..........................      Competitive local exchange carrier.  A company that competes with LECs in
                                    the local services market.
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.

FCC...........................      Federal Communications Commission.
fiber miles...................      The number of route miles installed along a telecommunications path
                                    multiplied by the number of fibers along the path.  See the definition of
                                    "route miles" below.
fiber optics..................      Fiber optic technology involves sending laser light pulses across glass
                                    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.
ILEC..........................      Incumbent local exchange carrier.
IP............................      Internet protocol.

                    Notes to Pro Forma Financial Information

                                   (Unaudited)

             For the nine month period ended September 30, 1999 and
                        the year ended December 31, 1998

            (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;

     These agreements are summarized in the consolidated financial statements of
the Company for the period ended December 31, 1998.

     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.

     The Company issued 26,080,000 Class A Non-voting shares and 4,920,000 Class
C multiple voting shares, to an executive officer of the Company, for
consideration of $77,500,000. In addition, the Company issued a note receivable

     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 nine month period ended September 30, 1999 are based on the

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

     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

                    Notes to Pro Forma Financial Information

                                   (Unaudited)

             For the nine month period ended September 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
     September 30, 1999

     (i) Issuance of shares

     In addition, this adjustment records the issuance of 26,080,000 Class A
Non-Voting shares and 4,920,000 Class C multiple voting shares, to the executive
officer. The issuance of shares will result in compensation expense in futures
periods. No adjustment for compensation expense has been recorded for these
proforma financial statements as the services to be provided will only be
received in the future and have no affect on operations presented for 1998 and
1999.

     (ii) Acquisition of CN /IC Minority Interests

     This adjustment records the Company's acquisition of the shares in WFI-CN
Fiber Inc. and units in Worldwide Fiber IC LLC in exchange for Class A
Non-Voting shares of the Company. This pro forma adjustment assumes a purchase
price of $100,000,000. The number of Class A Non-Voting shares issued may be
adjusted on an initial public offering in accordance with a formula specified in
the purchase agreement. The excess purchase price of $97,500,000 over the cost
of net assets has been allocated to goodwill. Goodwill will be amortized on a
straight-line basis over 20 years which is the estimated useful life of the
fiber optic network assets being constructed on the CN/IC routes.

5.   Pro Forma Consolidated Income Statement assumptions and adjustments for the
     nine month period ended September 30, 1999

     (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 nine month period ended September 30, 1999, which
is not reflected in this pro forma statement.

     (ii) Income taxes

     This adjustment records income taxes of $3,571,000 for the nine month
period ended September 30, 1999 using an effective tax rate of 41.1%.

                                   (Unaudited)

             For the nine month period ended September 30, 1999 and
                        the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     (iii) Capital taxes

     This adjustment records estimated additional BC Corporation Capital taxes
of $875,000 and Federal Large Corporation taxes of $656,000 resulting from the
issuance of the Notes.

     (iv) Amortization of Goodwill

     This adjustment records amortization of goodwill of $3,656,000 arising from
the acquisition of the CN/IC minority interest.

6.   Pro forma consolidated income statement assumptions and adjustments for the
     year ended December 31, 1998

     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, the effect of the additional interest expense,
including amortization of deferred financing costs, related to the Notes and
1998 Notes, and the amortization of goodwill arising from the acquisition of the
CN/IC minority interests.

     (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.

                    Notes to Pro Forma Financial Information

                                   (Unaudited)

             For the nine month period ended September 30, 1999 and
                        the year ended December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)


     (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 $26,710,000 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, 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.

            (tabular amounts expressed in thousands of U.S. dollars)


     (vii) Amortization of Goodwill

     This adjustment records amortization of goodwill of $4,875,000 arising from
the acquisition of the CN/IC minority interest.

                   Notes to Consolidated Financial Statements

                               September 30, 1999

            (tabular amounts expressed in thousands of U.S. dollars)

                                   (Unaudited)


1.   The Company

     Worldwide Fiber Inc. (the "Company") is indirectly a 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. All share amounts have been presented on a post stock split basis
(note 10).

Significant Transactions

     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 159,997,600 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.

     On September 9, 1999, the Company amended its share capital by
re-designating 200,000,000 Class A Voting Shares to Class B Subordinate Voting
Shares, cancelling its remaining classes of shares and creating Class A
Non-Voting Shares, Class C Multiple Voting shares, Series A and B Convertible
Preferred Shares and Series C Redeemable Preferred Shares. Subsequently, the
Company declared a stock dividend of 5,000,000 (pre-split) Series C Redeemable
Preferred Shares for $5,000,000. Concurrently, the Company repurchased the
200,000,000 outstanding Class B Subordinate Voting Shares from its parent in
exchange for the issuance of 190,748,000 Class B Subordinate Voting Shares and
40,000,000 (pre-split) Series C Redeemable Preferred Shares. The Company then
redeemed the 45,000,000 (pre-split) outstanding Series C redeemable preferred
shares for $45,000,000 cash resulting in a charge to retained earnings of
$40,000,000.

     On August 31, 1999 the Company issued 1,200,000 Class B Subordinate Voting
Shares (re-designated from Class A Voting Shares) for $3,000,000 cash and on
September 9, 1999, the Company issued 70,934,464 Series A Non-Voting Convertible
Preferred Shares for $345,000,000 cash (Note 6).

     On May 28, 1999, the Company entered into an agreement with affiliates of
Ledcor, whereby the Company would acquire certain fiber optic network assets.
Closing occurred on September 27, 1999. As consideration, the Company issued
36,000,000 Class C Multiple Voting shares to affiliates of Ledcor. In addition,
the Company assumed certain rights and obligations under build agreements with a
third party including obligations relating to the completion of those builds and
certain support structure, maintenance, license and access, and underlying
rights obligations. The cost of the fixed assets acquired amounted to

                   Notes to Consolidated Financial Statements

                               September 30, 1999

            (tabular amounts expressed in thousands of U.S. dollars)

                                   (Unaudited)


$26,349,800, the cost of the assets in the accounts of Ledcor. The Company also
received a deferred tax benefit of $7,759,000, as a result of a higher tax cost
versus accounting cost of fixed assets. The Company also recorded deferred
revenue of $25,000,000 relating to a build commitment assumed from Ledcor.

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. Certain comparative figures have been
restated to conform with the current period presentation.

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
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.

Stock Option Plan

     The Company accounts for stock option grants in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25"), and, accordingly, recognizes compensation expense for stock option
grants to the extent that the estimated fair value of the stock exceeds the
exercise price of the option at the measurement date. The compensation expense
is charged against operations ratably over the vesting period of the options.

Short term investments

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

than not that the deferred tax assets will be fully utilized, therefore, no
valuation allowance has been recorded.

6.   Redeemable Convertible Preferred Stock

     On September 9, 1999 the Company authorized the following series of
preferred shares (note 1):

100,000,000,000     Series A Non-Voting Convertible Preferred Shares

100,000,000,000     Series B Subordinate Voting Convertible Preferred Shares

45,000,000          Series C Redeemable Preferred Shares

Series A Non-Voting Convertible Preferred Shares

     On September 9, 1999 the Company issued 70,934,464 Series A Non-Voting
Convertible Preferred Shares ("Series A Preferred Shares") for $345,000,000 in
cash.

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

     The Series A Preferred Shares have a mandatory redemption on November 2,
2009 at a liquidation value consisting of the original purchase price of $38.909
per share plus an adjustment equal to 6% per annum of the purchase price, plus
declared and unpaid dividends and the excess of the market value of the Class A
Non-Voting Shares over the liquidation value.

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

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

Series B Subordinate Voting Convertible Preferred Shares

     As at September 30, 1999, there are no Series B Subordinate Voting
Convertible Preferred Shares ("Series B Preferred Shares") outstanding.

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

     The Series B Preferred Shares are entitled to one vote per share.

     The Series B Preferred Shares are mandatorily redeemable on November 2,
2009 at a liquidation value of $38.909 per share plus an adjustment equal to 6%
per annum of the purchase price, plus declared and unpaid dividends and the
excess of the market value of the Class B Subordinate Voting Shares over the
liquidation value.

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

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

Series C Redeemable Preferred Shares

     On September 9, 1999 5,000,000 Series C Redeemable Preferred Shares
("Series C Preferred Shares") were issued pursuant to a stock dividend and
40,000,000 Series C Preferred Shares were issued pursuant to a share
re-organization. Subsequently, the Company repurchased the 45,000,000 issued
Series C Preferred Shares for $45,000,000 (note 1). As at September 30, 1999, no
Series C Preferred Shares are outstanding.

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 159,997,600 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.

     All share amounts have been retroactively adjusted for the eight-for-one
stock split on November 18, 1999 (note 14).

     Use of estimates

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

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)

     Cash and cash equivalents

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

     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.

            (tabular amounts expressed in thousands of U.S. dollars)

     Unbilled revenue

     Revenue recognized using the percentage-of-completion basis (see "Revenue
recognition") less billings to date is recorded as unbilled revenue.

     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.

             Notes to Consolidated Financial Statements (continued)

                                December 31, 1998

            (tabular amounts expressed in thousands of U.S. dollars)


     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 con-

            (tabular amounts expressed in thousands of U.S. dollars)


struction 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 the 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
          Fiber optic network assets.............................     4,424

                                                                     ======

     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

            (tabular amounts expressed in thousands of U.S. dollars)


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.

     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.

6.   Due from parent

     The components of the amount due from parent consist of the following:

         Contract amounts billed to parent..................     $180,593
         Costs charged by parent

     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.

            (tabular amounts expressed in thousands of U.S. dollars)

     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.

12.  Segmented information

     The Company operates within a single operating segment being the
construction and installation of fiber optic network assets. These fiber optic
network assets are being constructed in Canada and the United States. Revenues,
fixed assets, and deferred financing costs are located as follows:

14.  Subsequent events

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.

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.

Common stock

     Subsequent to year end, the Company granted stock options to employees and
officers to purchase an aggregate of 21.6 million shares of Class A Non-Voting
Shares of the Company at prices between $1.25 and $2.50 per share. The stock
options have terms expiring on or before September 30, 2009.

CN/IC 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.

     The Company entered into a commitment with CN and IC to acquire their
respective 25% interests in WFI-CN Fiber Inc. and Worldwide Fiber IC LLC in
exchange for Class A Non-Voting Shares of the Company. The number of Class A
non-voting shares to be issued by the Company may be adjusted on an initial
public offering in accordance with a formula specified in the agreement.

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 36,000,000 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. The cost of
the fixed assets acquired amounted to $26,349,800, the cost of the assets in the
accounts of Ledcor. The Company also received a deferred tax benefit of
$7,759,000, as a result of a higher tax cost versus ac-

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 (pre-split) Series C Redeemable Preferred Shares. Concurrently, the

Shares from its parent in exchange for the issuance of 190,748,000 Class B
Subordinate Voting Shares and 40,000,000 (pre-split) Series C Redeemable
Preferred Shares. The Company then redeemed the 45,000,000 (pre-split)
outstanding Series C Redeemable Preferred Shares for $45,000,000 of cash.

Issuance of Shares

     On August 31, 1999 the Company issued 1,200,000 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 70,934,464 Series A Non-Voting Preferred
Shares for $345,000,000 of cash.

Company to sell 26,080,000 Class A Non-Voting shares and 4,920,000 Class C
Multiple Voting shares for consideration of $77,500,000. In addition, the
Company issued a note receivable in the amount of $77,500,000 to the executive
officer.

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
          from WFI and its affiliates indefeasible rights of use for 24 fiber
          optic strands from its Chicago-New Orleans route if and when built, at
          fair value. These options expire one year after the strands are
          available.

     (iii) If WFI were to issue shares in a public offering having an aggregate

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.

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

                                                                 ============

     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.

                                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

             LEDCOR INDUSTRIES LIMITED--TELECOMMUNICATIONS DIVISION

                  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-56

                  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.

     Costs and billings on uncompleted contracts included in the divisional
financial statements are as follows:

</TABLE>

     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:

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

<S>                                                                   <C>                <C>                 <C>
   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.

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 information
called for by the applicable  registration  form with respect to reofferings by
persons who may


                                      II-7
<PAGE>

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

Worldwide Fiber Inc.
1510 - 1066 West Hastings Street
Vancouver, B.C.
V6E 3X1

Dear Sirs/Mesdames:


Re:   WORLDWIDE FIBER INC. --
      FORM-4 REGISTRATION STATEMENT

We are Canadian counsel for Worldwide Fiber Inc. (the "Company"). In this regard
we  have  been   requested  to  provide  an  opinion  in  connection   with  the
US$500,000,000  aggregate principal amount of the Company's 12% Senior Notes due
2009 (the  "Exchange  Notes")  which are appended as Exhibit A to the  Indenture
(defined below), to be registered pursuant to a Form F-4 Registration  Statement
(the  "Registration  Statement"),  filed with the United States  Securities  and
Exchange Commission. We have been advised by representatives of the Company that
the Exchange Notes will be issued  pursuant to an indenture dated as of July 28,
1999 (the  "Indenture"),  between the Company and HSBC Bank USA, as Trustee,  in
connection  with the exchange offer pursuant to which the Exchange Notes will be
issued for a like principal amount of the Company's  outstanding  US$500,000,000
12% Senior Notes due 2009.

For the purposes of our opinion, we have examined the following:

(a) an executed copy of the Indenture;  (b) an executed copy of the Registration
Statement; and (c) the Articles and by-laws of the Company.

For the purposes of this opinion, we have also examined originals, facsimiles or
copies certified or otherwise  identified to our  satisfaction,  of comments and
instruments, such statutes, such records of corporate proceedings,  certificates
of  corporate  officers,  certificates  of  governmental  offices and such other
documents and materials as we have considered necessary or appropriate.  In such
examination we have assumed the genuineness of all signatures,  the authenticity
of all documents  submitted to us as originals,  the completeness and conformity
to the originals of all documents  submitted to us as facsimiles or copies,  and
the authenticity of the originals of such facsimiles or copies.

We are  qualified  to  express  opinions  only with  respect  of the laws of the
Province of British  Columbia  and the laws of Canada  applicable  therein.  The
opinions expressed herein are made as of the date hereof.

We are of the opinion that:

1.  The Company is a corporation  incorporated  under the laws of Canada and has
    the  corporate  power and  capacity to own and lease its property and assets
    and to carry on its business as described in the Registration Statement.

2.  The Company has the corporate  power and capacity to execute and deliver the
    Exchange Notes and to consummate the transactions contemplated thereby.

3.  The execution by the Company of, and the  performance by the Company of, its
    obligations  under the Exchange Notes and the consummation by the Company of
    the  transactions  contemplated  thereby  have been duly  authorized  by the
    necessary corporate action on the part of the Company.

Consent is hereby given to the use of our name under the  captions  "Description
of  Notes--Enforceability  of Judgments," "Legal Matters" and "Enforceability of
Civil  Liabilities  Against Foreign  Persons" in the Prospectus  included in the
Registration  Statement  and to the  filing,  as an exhibit to the  Registration
Statement,  of this letter.  In giving such consent we do not admit that we come
within the category of persons whose consent is required  under Section 7 of the
United States Securities Act of 1933.

Cahill Gordon & Reindel in its opinion filed as Exhibit 5.2 to the  Registration
Statement, is entitled to rely on this opinion.

Yours truly,

/s/ FARRIS, VAUGHAN, WILLS & MURPHY







                    (LETTERHEAD OF CAHILL GORDON & REINDEL)






                                   January 19, 1999



                                                            (212) 701-3000


                        Re: Worldwide Fiber, Inc.
                            Registration Statement on
                            Form F-4 (No. 333-89695)

Dear Ladies and Gentlemen:

            We have acted as  special  counsel  for  Worldwide  Fiber Inc.  (the
"Company")  in  connection  with  the  Registration  Statement  on Form F-4 (the
"Registration  Statement") filed by the Company with the Securities and Exchange
Commission (the "Commission") for registration under the Securities Act of 1933,
as amended (the "Act"), of $500,000,000 principal amount of 12% Senior Notes due
2009 of the Company (the  "Exchange  Notes").  The Exchange Notes will be issued
pursuant to an indenture dated as of July 28, 1999 (the "Indenture") between the
Company and HSBC Bank USA, as Trustee.  The Registration  Statement was filed in
connection with the exchange offer (the "Exchange  Offer") pursuant to which the
Exchange  Notes  will be issued  for a like  principal  amount of the  Company's
outstanding 12% Senior Notes due 2009 (the "Old Notes").

            In  connection  therewith,  we have  examined,  among other  things,
originals or copies,  certified or otherwise identified to our satisfaction,  of
the  Certificate of  Incorporation  of the Company,  resolutions of the Board of
Directors  of the  Company  with  respect  to  the  filing  of the  Registration
Statement and such other  documents as we have deemed  necessary or  appropriate
for the purpose of rendering this opinion.

            In our examination of documents,  instruments  and other papers,  we
have  assumed  the  genuineness  of all  signatures  on original  and  certified
documents and the  conformity to original and certified  documents of all copies
submitted to us as  conformed,  photostatic  or other  copies.  As to matters of
fact, we have relied upon representations of officers of the Company.

            Based upon the foregoing,  and subject to the qualifications  stated
herein, it is our opinion that, assuming due authorization of the Exchange Notes
by the Company, the Exchange Notes, when duly executed and delivered in exchange
for the Old Notes in  accordance  with the terms of the  Exchange  Offer and the
Indenture as contemplated by the Registration  Statement,  will constitute valid
and legally binding obligations of the Company,  entitled to the benefits of the
Indenture and  enforceable  against the Company in  accordance  with their terms
except  that  the  enforcement   thereof  may  be  subject  to  (i)  bankruptcy,
insolvency,  reorganization,  fraudulent conveyance, moratorium or other similar
laws now or hereafter in effect relating to creditors' rights generally and (ii)
general  principles  of equity and the  discretion of the court before which any
proceeding therefor may be brought.

            We are  attorneys  admitted to practice in the State of New York. We
express no opinion  concerning the laws of any jurisdiction  other than the laws
of the United States of America and the State of New York.

            We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the Registration  Statement and related  Prospectus.  Our consent to
such  reference  does not constitute a consent under Section 7 of the Act as, in
consenting to such reference, we have not certified any part of the Registration
Statement  and do not  otherwise  come within the  categories  or persons  whose
consent is required  under said Section 7 or under the rules and  regulations of
the Securities and Exchange Commission thereunder.

                                                Very truly yours,

                                                /s/ CAHILL GORDON & REINDEL

                              W I T N E S S E T H :

     WHEREAS, the Corporation wishes to sell to the Investors, and the Investors

     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

     1.3. Deliveries at the Closing. (a) At the Closing, the Corporation shall

     (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.

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

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

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

upon the amount of each Investor's original investment), at no additional cost

the application of any anti-dilution, ratable treatment or similar provisions as

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

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

presently required. To the knowledge of the Corporation, no other party to any

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

     5.4. Tax Indemnity. (a) The Corporation shall indemnify and hold each
Investor, or the partners of the Investor where the Investor is a partnership,

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-
<PAGE>

(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

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.

     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
respect thereto including, but not limited to, that certain letter of intent,
dated August 5, 1999, between the Corporation and the Investors.

     SECTION 16. 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 fax, nationally
recognized overnight courier or first class registered or certified mail, return
receipt requested, postage prepaid, addressed to such party at the address set

permanently, pursuant to the written consent of the Corporation and each of the
Investors.

     SECTION 18. Counterparts. This Agreement may be executed in any number of

instrument, but all such counterparts together shall constitute but one
agreement.

     SECTION 19. Headings. 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.

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

Agreement shall be interpreted in such manner as to be



                                      -48-

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.

     SECTION 23. Currency. Unless otherwise indicated, references to "dollars",
"$" or U.S. dollars and references to "C$" are to Canadian dollars.

     SECTION 24. No Partnership. The obligations of each of the parties to this

deemed to imply a partnership, joint venture or other relationship between the
parties.

<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-

                                      -13-


vestors and Investor Affiliates) or Section 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, 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


<PAGE>


                                      -14-


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


<PAGE>
                                      -16-


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-

                                      -17-


poration (or such other place as is mutually agreed upon by the parties) on the
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;
(iii) Common Shares or Common Share Equivalents issued and outstanding on the
date hereof or Common Shares issued upon the conversion or exercise of any such
outstanding Common Share Equivalents; (iv) Common Shares issued or issuable as

IPO; (vi) Common Shares issued pursuant to a Minority Roll-Up Transaction; or

     (c) Without limiting paragraphs (a) or (b) above, the Corporation shall, at
the request of any of the Investors, cause a Investor Designee to be appointed
or elected in each case to each of the other committees of the Board, provided
that, following an IPO, such Investor Designee meets the qualifications
necessary to serve on such committee established in compliance with Section 9.
If any director serving on any committee shall cease to serve as a director of
the Corporation for any reason or otherwise is unable to fulfill his or her
duties on any such committee, he or she shall be succeeded by another director

     8.5. Directors' Indemnification.

insurance in an amount of at least US$5,000,000 or more and upon such terms as
are reasonably acceptable to the Investors.

     (b) The Articles of Continuance, or By-Laws, or both, shall to the fullest
extent permitted by law provide for indemnification of, and advancement of
expenses to, and limitation of the personal liability of, the directors of the
Corporation or such other person or persons, if any, who, pursuant to a
provision of such Articles of Incorporation, exercise or perform any of the
powers or duties otherwise conferred or imposed upon such directors, which
provisions shall not be amended, repealed or otherwise modified in any manner
adverse to the directors until at least six (6) years following the date that
the Investors are no longer entitled to designate directors pursuant to this
Section 8.

     8.6. No Expansion of Duties. The parties acknowledge that the Investors and
their Investor Affiliates have investments in other business similar to and
which may compete with the Corporation's businesses ("Competing Businesses") and
reserve the right to make additional investments in other Competing Businesses
independent of their investments in the Corporation. By virtue of an Investor
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
Investor) shall have any right with respect to any such investments or
activities undertaken by such Investor. Without limitation of the foregoing,
each Investor or any Investor Affiliates may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Corporation or any
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



<PAGE>
                                      -22-


take for their own respective account or to recommend to others any such
particular investment opportunity.

     8.7. Expenses. The Corporation shall pay all reasonable travel expenses and
other out-of-pocket disbursements incurred by the directors to attend meetings
of the Board, of any Subsidiary board of directors or of any committees thereof.

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
agree that all of the following provisions of this Section 12 are for the
exclusive benefit, protection and enjoyment of each of the Investors (severally

enforced or remedied by the Investors (severally and not jointly) and their
permitted successors and assigns.

     12.2. Additional Issuances. The Corporation agrees that, anything contained
herein to the contrary notwithstanding, (a) any Person to which Shares are
issued in a Private Sale after the date hereof and who after giving effect to
such Issuance, would own more than 1% in the aggregate of the then total

     12.3. Ledcor Roll-Up Transactions. Ledcor and the Corporation shall
consummate the transaction contemplated by the Ledcor Roll-Up Agreement in
accordance with its terms. Neither Ledcor nor the Corporation shall amend,
modify or waive, temporarily or permanently, any of the terms or provisions of
the Ledcor Roll-Up Agreement in any manner adverse to the Corporation or the

     12.4. Ledcor Roll-Up Failure. In the event that the Corporation shall not

earliest of the date of any corporate action approving, the record date of, or
the effective date of, a transaction of the nature referred to in Section
9(b)(i) (without giving effect to the proviso thereto), (y) the date any Section
5 Notice is given by WFH, Ledcor or their Affiliates (other than a Sale pursuant
to Section 3(a)(ii)), or (z) September 30, 1999, in consideration for the
issuance of 4,500,000 Common Shares in accordance with the terms of the Ledcor
Roll-Up Agreement (a "Ledcor Roll-Up Failure"), each Investor (a "Section 12.4
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.

     12.5. Access to Records. From and after the Closing and so long as an
Investor or its Permitted Assigns continue to hold any Series A Non-Voting

the Investors. The Corporation and each of the Investors further agree that,

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

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

Agreement.

     (ii) WFH shall not sell, assign or otherwise dispose of any capital shares

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

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".

     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.

     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,

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,
and hereby further irrevocably and

<PAGE>

                                      -44-


unconditionally waives and agrees not to plead or claim in any such court that
any such Litigation brought in any such court has been brought in an
inconvenient forum. Each of the parties irrevocably and unconditionally waives,
to the fullest extent permitted by applicable law, any and all rights to trial
by jury in connection with any Litigation arising out of or relating to this
Agreement or the transactions contemplated hereby.

     SECTION 24. Successors and Assigns. This Agreement shall inure to the
benefit of and shall be binding upon the parties hereto and their respective
successors, assigns, heirs and personal representatives. Except pursuant to a
Sale of Shares permitted by Section 3, no Shareholder shall have the right to
assign its rights and obligations under this Agreement without the consent of
the other Shareholders. No Shareholder shall have the right to assign its rights
under Section 7 or 8 of this Agreement without the consent of the Corporation
and each other Investor. Upon any such assignment, such assignee shall have and
be able to exercise all rights of the assigning Shareholder. 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 (including, for the avoidance of doubt, under Section 7 or
8) 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 then current
partners, members or other equity holders of such Investor (the "Investor
Affiliates"), without the consent of the Corporation or any other Shareholder.
Notwithstanding the foregoing, neither the Corporation nor any Person controlled
by the Corporation shall be deemed to be an Investor Affiliate of any Investor
for purposes of this Agreement. Upon any such assignment, the assignee shall
have and be able to exercise all rights of the assigning Shareholder.

     SECTION 25. 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 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

                              WORLDWIDE FIBER INC.

                            STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT (the "Agreement") is made as of the 22nd day
of December, 1999 (the "Effective Date"), by and between WORLDWIDE FIBER INC., a
corporation incorporated under the laws of Canada (the "Company"), and GREGORY
B. MAFFEI (the "Purchaser") (collectively, the "Parties").

                                    RECITALS

     WHEREAS, the Company and the Purchaser have entered into an Employment
Agreement, dated December 22, 1999, pursuant to which the Company has agreed to
employ the Purchaser, and the Purchaser has agreed to serve as the President and
Chief Executive Officer of the Company (the "Employment Agreement"); and

     WHEREAS, the Company desires to issue, and Purchaser desires to acquire,
stock of the Company as herein described, on the terms and conditions
hereinafter set forth.

     NOW, THEREFORE, IT IS AGREED between the Parties as follows:

     Section 1. Purchase and Sale of Stock. Purchaser hereby agrees to purchase
from the Company, and the Company hereby agrees to sell to Purchaser, an
aggregate of thirty one million (31,000,000) shares of common stock of the
Company, of which twenty six million eighty thousand (26,080,000) shares will be
Class A Non-voting Shares of the Company (the "Class A Shares") and four million
nine hundred twenty thousand (4,920,000) shares will be Class C Multiple Voting
Shares of the Company (the "Class C Shares") (collectively, the "Shares"), at
two dollars and fifty cents (U.S. $2.50) per share (the "Purchase Price Per
Share"), for an aggregate purchase price of seventy seven million five hundred
thousand dollars (U.S. $77,500,000) (the "Purchase Price"). The Purchase Price
shall be payable by certified check or wire transfer. The Company will cause its
affiliate Worldwide Fiber Finance Ltd. to lend the Purchase Price to Purchaser
against delivery of a promissory note payable to Worldwide Fiber Finance Ltd. in
the form attached hereto at Tab 1. The closing hereunder, including the loan of
the Purchase Price and payment for and delivery of the Shares, shall occur at
the offices of the Company immediately following the execution of this
Agreement, or at such other time and place as the Parties may mutually agree.

     Section 2. Repurchase Option.

     (a) Repurchase Option. In the event Purchaser's employment by the Company,
(A) terminates for any or no reason, or (B) Purchaser fails to commence
employment with the Company on or before January 31, 2000 as a result of (i) his
death or Disability or (ii) for a reason which would have constituted a
termination by the Purchaser without Good Reason pursuant to Section 5(d) of the
Employment Agreement had the Purchaser commenced his employment with the Company
and then terminated his employment for such reason then the


<PAGE>

Company shall have an irrevocable option (the "Repurchase Option"), which shall
be exercisable during the ninety (90) day period after said termination or such
longer period as may be agreed to by the Company and the Purchaser in writing,
to repurchase from Purchaser for the Option Price, subject to adjustment
pursuant to Section 2(d), that number of Shares that have not ceased to be
subject to the Repurchase Option in accordance with the provisions of Section
2(b) below as of such termination date.

     (b) Lapse of Repurchase Option.

          (i) General Provisions. Seventy five percent (75%) of the Shares, all
     of which will be Class A Shares, shall initially be subject to the
     Repurchase Option and, therefore, 7,750,000 Shares, of which 4,920,000
     Shares will be Class C Shares and 2,830,000 Shares will be Class A Shares,
     are immediately vested upon the execution of this Agreement and will never
     be subject to the Repurchase Option; provided, however, that if the
     Purchaser fails to commence employment with the Company on or before
     January 31, 2000 as a result of (i) his death or Disability or (ii) for a
     reason which would have constituted a termination by the Purchaser without
     Good Reason pursuant to Section 5(d) of the Employment Agreement had the
     Purchaser commenced his employment with the Company and then terminated his
     employment for such reason then, in addition to the Company's repurchase
     right outlined in Section 2(a) of this Agreement: (1) the Company shall
     have the option, which shall be exercisable during the thirty (30) day
     period after said termination to repurchase from Purchaser for an amount
     equal to the lesser of (i) the Fair Market Value of the Shares calculated
     on the date of repurchase, or (ii) the Option Price, subject to adjustment
     pursuant to Section 2(d), the 7,750,000 Vested Shares and (2) neither the
     Purchaser nor the Company shall have any further obligations or liabilities
     to the other Party under this Agreement, the Employment Agreement, after
     Purchaser has repaid that certain promissory note dated December 22, 1999
     by and between the Purchaser and Worldwide Fiber Finance Ltd., such
     promissory note, or otherwise (except for Purchaser's obligations under
     Section 7 of the Employment Agreement). Subject to the provisions of
     Section 2(b)(ii) and Section 2(b)(iii) of this Agreement, the Shares that
     are initially subject to the Repurchase Option shall cease to be subject to
     the Repurchase Option according to the following schedule, provided that
     the Purchaser is employed by the Company (or a parent or subsidiary of the
     Company) on such date:

                                            Number of Shares that cease to be
     Date                                    subject to the Repurchase Option
     ----                                   ---------------------------------

     December 22, 2000                                  6,200,000

     The last day of each calendar month                  568,332
     following December 22, 2000



                                      -2-
<PAGE>

          (ii) Change of Control Provisions. Notwithstanding the preceding
     provisions of Section 2(b)(i): (A) upon the occurrence of a Change of
     Control, 40% of the remaining unvested Shares shall cease to be subject to
     the Repurchase Option (i.e., the Repurchase Option shall lapse on such date
     with respect to 40% of the Shares that remain subject to the Repurchase
     Option immediately prior to such date), and (B) if at any time during the
     two-year period immediately following the occurrence of a Change of
     Control, Purchaser ceases for any reason other than a termination of
     service or employment by the Company or its successor for Cause pursuant to
     Section 5(a) of the Employment Agreement or by the Executive without Good
     Reason pursuant to Section 5(d) of the Employment Agreement, to be (1) a
     member of the Board of the surviving entity, and/or (2) the President
     and/or Chief Executive Officer of the surviving entity on terms that are at
     least as favorable as the then current terms of the Employment Agreement,
     then 100% of the remaining unvested Shares shall cease to be subject to the
     Repurchase Option (i.e., the Repurchase Option shall lapse in its entirety
     on the date Purchaser ceases to be the President, Chief Executive Officer,
     or a member of the Board of the surviving entity).

          (iii) Termination of Employment Without Cause or For Good Reason.
     Notwithstanding the preceding provisions of Section 2(b)(i), upon the
     earliest to occur of: (a) the date that Purchaser's employment is
     terminated by the Company without Cause pursuant to Section 5(d) of the
     Employment Agreement; or (b) the date that Purchaser's employment is
     terminated as a result of his death or Disability pursuant to Section 5(b)
     of the Employment Agreement, or (c) the date the Purchaser terminates his
     employment with the Company for Good Reason pursuant to Section 5(c) of the
     Employment Agreement (clauses (a), (b) and (c) each being a "Termination
     Event" and, collectively, the "Termination Events"), (x) if a Termination
     Event occurs on or prior to December 22, 2000, that amount of Shares will
     cease to be subject to the Repurchase Option equal to the sum of: (A)
     twenty percent (20%) of the Shares plus (B) that number of Shares obtained
     by multiplying the total number of Shares purchased under this Agreement by
     the product of .0183333 by the number of calendar months that the Company
     employed Purchaser for the period beginning on the Effective Date and
     ending on the date that his employment by the Company terminated and (y) if
     a Termination Event occurs after December 22, 2000, twenty two percent
     (22%) of the Shares will cease to be subject to the Repurchase Option.

     (c) Exercise of Repurchase Option. The Repurchase Option shall be exercised
by written notice signed by an officer of the Company or by any assignee or
assignees of the Company and delivered or mailed as provided in Section 19(a).
Such notice shall identify the number of Shares to be purchased and shall notify
Purchaser of the time, place and date for settlement of such purchase, which
shall be scheduled by the Company within thirty (30) days of receipt of such
notice. The Company, or any assignee or assignees of the Company, shall, at its
or their option, pay for any Shares purchased pursuant to the Repurchase Option
by certified check, by offset against any indebtedness owing to the Company (or
to such assignee



                                      -3-
<PAGE>

or assignees, in the case of an exercise of the Repurchase Option by such
assignee or assignees) by Purchaser or by reducing Purchaser's outstanding debt
under the promissory note delivered to Worldwide Fiber Finance Ltd. by Purchaser
pursuant to Section 1 of this Agreement, or by any combination thereof. Upon
delivery of such notice and payment of the purchase price in any of the ways
described above, the Company, or any assignee or assignees of the Company (as
applicable), shall become the legal and beneficial owner of the Shares being
repurchased and all rights and interest therein or related thereto, and the
Company shall have the right to transfer to its own name or the name of any
assignee or assignees of the Company the Shares being repurchased by the
Company, or any assignee or assignees of the Company without further action by
Purchaser.

     (d) Adjustments to Stock. If, from time to time, during the term of the
Repurchase Option there is any change affecting the outstanding Stock as a class
that is effected without the receipt of consideration by the Company (through
merger, consolidation, reorganization, reincorporation, stock dividend, dividend
in property other than cash, stock split, liquidating, dividend, combination of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), then any and all new, substituted or
additional securities or other property which Purchaser receives and/or to which
Purchaser is entitled by reason of Purchaser's ownership of Shares shall be
immediately subject to the Repurchase Option and be included in the word
"Shares" for all purposes of the Repurchase Option with the same force and
effect as the Shares currently subject to the Repurchase Option, but only to the
extent the Shares are, at the time, covered by such Repurchase Option. While the
total Option Price shall remain the same after each such event, the Option Price
per Share upon exercise of the Repurchase Option shall be appropriately
adjusted.

     (e) Termination of Repurchase Option. Section 2 of this Agreement shall
terminate upon the exercise in full or expiration of the Repurchase Option,
whichever first occurs.

     Section 3. Joinder to the Shareholders Agreement. As of the Effective Date,
the Purchaser hereby agrees to join the Shareholders Agreement and, for all
purposes of such Shareholders Agreement to constitute, and be entitled to the
benefits, rights and features (subject to the obligations) associated with his
constituting, a "Shareholder" as that term is defined in the Shareholders
Agreement.

     Section 4. Demand Registration Rights.

     (a) Request for Registration. Subject to Section 4(b) of this Agreement,
Purchaser shall be entitled to make a written request ("Demand Registration
Request") to the Company for registration with the Commission under and in
accordance with the provisions of the Securities Act of all or part of the
Shares owned by him (a "Demand Registration") (which Demand Registration Request
shall specify the intended number of Shares to be disposed of by Purchaser and
the intended method of disposition thereof); provided, that the Company may, if
the Board so determines in the exercise of its reasonable, good faith judg-



                                      -4-
<PAGE>

ment that due to a pending or contemplated acquisition or disposition or public
offering or other similar occurrence it would be inadvisable to effect such
Demand Registration at such time, defer such Demand Registration for a single
period not to exceed one hundred eighty (180) days; provided, however, in the
event that the Company proposes to register shares of its stock under the
Securities Act, whether or not for sale for its own account, during such single
period, Purchaser shall have the right to exercise his Incidental Registration
Rights as outlined in Section 5 of this Agreement with respect to such
registration. Within ten (10) days after receipt of such request, the Company
will use its best efforts to effect the registration under the Securities Act of
the Shares which the Company has been so requested to register by Purchaser.

     (b) Number of Demand Registrations. At any time on or after the earlier of:
(A) the date of the Company's IPO or (B) September 7, 2001, Purchaser shall be
entitled to make one Demand Registration Request at any time; provided, that (i)
the number of Shares subject to any such Demand Registration represents at least
twenty five percent (25%) of the number of Shares held, directly or indirectly,
by Purchaser immediately prior to his Demand Registration Request, (ii) the
Company shall not be obligated to effect more than one Demand Registration and
(iii) Purchaser shall not be entitled to make a Demand Registration Request
during any period during which (A) all of the Shares may be freely transferred
at the same time pursuant to Rule 144 promulgated under the Securities Act, or
(B) all of the Shares have been properly registered on a registration statement,
such registration statement is effective under the Securities Act and all of the
Shares may be freely transferable pursuant to such registration statement.

     (c) Effective Registration and Expenses. A registration will not count as a
Demand Registration until it has become effective (unless Purchaser withdraws
the Shares, in which case such demand will count as a Demand Registration unless
Purchaser agrees to pay all Registration Expenses). The Company shall be solely
responsible for any and all costs and expenses of all registrations and
qualifications under the Securities Act, and of all other actions the Company is
required to take in order to effect the registration of Shares under the
Securities Act whether pursuant to this Agreement or otherwise.

     (d) Priority on Demand Registrations. If the offering of Purchaser's Shares
pursuant to such Demand Registration is in the form of an underwritten offering
and the managing underwriter or underwriters of such offering advise the Company
and Purchaser in writing that in their opinion the number of Shares requested to
be included in such offering is sufficiently large to adversely affect the
success of such offering, the Company will include in such registration the
aggregate number of shares which in the opinion of such managing underwriter or
underwriters can be sold without any such adverse effect, and such amount shall
be allocated in the following order of priority: (i) first, the Shares of the
Purchaser subject to any such Demand Registration and (ii) second, any shares of
common stock that the Company or any other holder proposes to sell.



                                      -5-
<PAGE>

     Section 5. Incidental Registration Rights. As of the Effective Date, the
Company, certain shareholders of the Company and the Purchaser will enter into a
Joinder to the Shareholders Agreement substantially in the form attached hereto
at Tab 5, which shall provide that for purposes of Section 2.2 and all related
Sections of the Registration Rights Agreement, Purchaser shall constitute, and
shall be entitled to all of the benefits, rights and features associated with
being, a "Holder of record of Registrable Securities."

     Section 6. Commitment to Register Shares. As soon as permitted under the
Securities Act following an IPO, the Company will register the Shares purchased
or otherwise acquired by the Purchaser pursuant to this Agreement on a Form S-8
and/or such other form as may be required to permit the sale of such Shares then
held by Purchaser or any "permitted transferee," within the meaning of Form S-8
and/or any other applicable form, in the public market without any restriction,
other than restrictions that arise from the volume limitations of Rule 144.

     Section 7. Additional Registration Rights. If at any time, whether before
or after the Effective Date, the Company has granted or grants to any individual
or entity (an "Additional Investor") rights to register under an effective
registration statement pursuant to the Securities Act any shares of common stock
owned, directly or indirectly, by such Additional Investor, then the Company
shall also grant such registration rights to Purchaser with respect to any
Shares to the extent that such registration rights granted to such Additional
Investor in any way exceed, supplement, or otherwise provide increased benefit
or protection to such Additional Investor than the registration rights granted
to Purchaser under Sections 4, 5 or 6 of this Agreement; provided, that, the
Company will not grant registration rights to any Additional Investor unless
approved by the Board.

     Section 8. Put by the Purchaser. Upon the occurrence of any of the events
specified below, Purchaser or any Permitted Transferee shall have the right to
sell all or any portion of his Shares, whether vested or unvested, to the
Company (the "Put") as set forth below:

     (a) After Termination of Employment.

          (i) Pre-IPO. Prior to an IPO of the Company, if the Purchaser ceases
     to be employed by the Company for any reason, the Purchaser or any
     Permitted Transferee or, upon the death of either the Purchaser or any
     Permitted Transferee, his or her beneficiary shall at any time after such
     date of termination be entitled to exercise the Put (A) with respect to any
     Vested Share at a per Share price equal to the Fair Market Value of the
     Shares calculated as of the Exercise Date and (B) with respect to any
     Unvested Share at a per Share price equal to the lesser of (x) the Fair
     Market Value of a Share calculated as of the Exercise Date or (y) the
     Option Price per Share; and

          (ii) Post-IPO. Following an IPO of the Company, if the Purchaser
     ceases to be employed by the Company for any reason, the Purchaser or any
     Permitted Trans-



                                      -6-
<PAGE>

     feree or, upon the death of either the Purchaser or any Permitted
     Transferee, his or her beneficiary shall at any time after such date of
     termination be entitled to exercise the Put (A) with respect to any Vested
     Share at a per Share price equal to the Fair Market Value of the Shares
     calculated as of the Exercise Date; provided, however, that the aggregate
     amount of Shares that may be put to the Company pursuant to this clause (A)
     shall not exceed the Aggregate Put Amount and (B) with respect to any
     Unvested Share at a per Share price equal to the lesser (x) of the Fair
     Market Value of a Share calculated as of the Exercise Date or (y) the
     Option Price per Share.

     (b) During Employment.

          (i) Pre-IPO. Prior to an IPO of the Company, the Purchaser or any
     Permitted Transferee or, upon the death of either the Purchaser or any
     Permitted Transferee, his or her beneficiary shall be entitled to exercise
     the Put with respect to any Vested Share at a per Share price equal to the
     Fair Market Value of the Shares calculated as of the Exercise Date;
     provided, however, that the aggregate amount of Shares that may be put to

Purchaser shall exercise all rights and privileges of a shareholder of the
Company while the stock is held by you.

authorities or rights of the Parties executing or delivering or purporting to
