                               PROSPECTUS SUMMARY

   This summary highlights some information from this prospectus. Because this
is only a summary, it does not contain all of the information that may be
important to you. To understand all of the terms of the exchange offer and to
attain a more complete understanding of our business and financial situation,
you should read carefully the entire prospectus. In this prospectus, the
"Company," "we," "ours" and "us" refer to GlobeNet Communications Group Limited
and its subsidiaries, unless the context indicates otherwise. This prospectus
uses a number of technical terms, such as RFS and Gbps, that are not easily
understandable. We have defined certain technical terms used in this prospectus
in the glossary that is included at the end of this prospectus. Unless
otherwise specified, all references to "$" or "dollars" are to U.S. dollars.

                                  Our Company

   We will provide our customers with customized and flexible city-to-city
international telecommunications network solutions. We will be a "carriers'
carrier" and our principal customers will be international telecommunications
providers. We are currently developing the Atlantica-1 Network, a high capacity
undersea fiber optic cable system that, together with terrestrial extensions,
will offer seamless connectivity between certain major cities in the United
States, Brazil, Venezuela, Bermuda and Argentina. In addition, we intend to
expand the reach of the Atlantica-1 Network by offering connectivity to other
countries in South America and Europe through a combination of commercial
arrangements, capacity purchases and further development of undersea or
terrestrial fiber optic cable systems. We are developing the Atlantica-1
Network to satisfy increasing bandwidth requirements for the transmission of
voice, data and video, particularly over the Internet, between North America
and South America.

   We currently provide international telecommunications services to both
residential and commercial customers in Bermuda through our subsidiary
TeleBermuda International Limited ("TBI"). TBI, which commenced service in May
1997, is one of only two carriers that the government of Bermuda has licensed
to provide international telecommunications services to customers in Bermuda.
In November 1997, we successfully completed the deployment of the BUS-1
undersea fiber optic cable system, which connects Bermuda and the United
States. The BUS-1 system, which we will incorporate into the Atlantica-1
Network, established us as a full-service facilities-based provider of
international long-distance service for traffic originating and terminating in
Bermuda. We do not intend to offer telecommunications services to retail
customers outside of Bermuda.

   We are a Bermuda company. Our principal executive offices are located at 2
Carter's Bay Road, Southside, St. David's DDBX, Bermuda, and our phone number
is (441) 296-9000. Our common shares are publicly traded on the Bermuda Stock
Exchange under the symbol "GLOCOM."

                              Atlantica-1 Network

   The Atlantica-1 Network will be a 22,500 km four fiber pair undersea fiber
optic cable system. Alcatel Submarine Networks and Alcatel Submarine Networks,
Inc. (collectively, "Alcatel") will design, construct and install the
Atlantica-1 Network for us under a turnkey contract. We believe that the
deployment of the Atlantica-1 Network will position us as one of the first
private undersea fiber optic cable systems that, together with terrestrial
extensions, will offer city-to-city connectivity between the United States,
Brazil, Venezuela, Bermuda and Argentina.

   The Atlantica-1 Network will employ the most advanced undersea fiber optic
technology currently available. It will employ self-healing ring technology
that protects against outages caused by a system failure. The initial capacity
of the Atlantica-1 Network will be 40 Gbps of total capacity or 20 Gbps of
self-healing capacity. We will be able to upgrade the system to 1,280 Gbps of
total capacity or 640 Gbps of self-healing capacity. We will upgrade the system
incrementally in advance of expected demand.

                                       1
<PAGE>


   The principal components of the Atlantica-1 Network will be the primary
ring, the Rio extension and the Caracas extension:

  . Primary Ring: The primary ring will connect Tuckerton, New Jersey, St.
    David's, Bermuda, Fortaleza, Brazil, Punta Gorda, Venezuela and Boca
    Raton, Florida. The ready for service, or RFS, date for the connection
    from New Jersey to Brazil via Bermuda is September 2000, and the RFS date
    for the full ring is December 2000. The cost of the primary ring is
    approximately $502 million.

  . Rio Extension: The Rio extension will connect Fortaleza, Brazil and Rio
    de Janeiro, Brazil. The RFS date for the primary strand of the Rio
    extension is February 2001, and the cost is approximately $119 million.
    We have an option in our contract with Alcatel to build the secondary
    strand of the Rio extension for approximately $112 million. We intend to
    exercise this option unless we can obtain capacity on a terrestrial
    system from a third party at a lower cost. We expect the target service
    date to be approximately 18 months from the date of exercising the
    option.

  . Caracas Extension: The Caracas extension will connect Punta Gorda,
    Venezuela and Caracas, Venezuela. We are currently negotiating with
    Alcatel to build the Caracas extension. We estimate that the cost to
    build the Caracas extension will be $10 million. We expect the targeted
    service date to be in or about December 2000.

                                 Financing Plan

   We estimate that the total cost to build the Atlantica-1 Network, including
the secondary strand of the Rio extension, the Caracas extension, landing
stations and capital contingencies, will be approximately $825 million. This
estimate does not include potential costs, if any, associated with securing
terrestrial capacity, including any terrestrial extension to Buenos Aires,
Argentina. We also utilized approximately $57.2 million of the financing
described below to finance the repayment of certain existing indebtedness and
transaction costs. On July 14, 1999, we obtained approximately $986.0 million
of financing consisting of the following:

  . we issued the old notes in an aggregate principal amount of $300 million,

  . we issued 13,263,646 common shares (representing 67% of our common shares
    on a fully diluted basis) and 1,000 Class B shares, which have special
    voting rights, for an aggregate offering price of approximately $270.6
    million to certain institutional investors in a private equity financing,

  . our subsidiary GlobeNet Communications Holdings Ltd. ("Holdings") entered
    into a credit agreement with Toronto Dominion (Texas) Inc., Credit Suisse
    First Boston, New York branch, TD Securities (USA) Inc. and certain
    lenders under which, subject to certain terms and conditions, Holdings
    may borrow up to $400 million and may request an additional facility for
    up to $50 million, and

  . we retired subordinated loans in the principal amount of $13.5 million
    when our subordinated lenders elected to effectively convert the
    principal and $1.9 million of accrued interest on their subordinated
    loans into 1,635,286 common shares.

   On August 9, 1999, we accepted for repurchase 1,500,000 common shares held
by existing shareholders at $20.40 per share (less expenses) for an aggregate
price of $30.6 million. We paid this repurchase price out of a portion of the
proceeds of the private equity financing described above.

   We are now offering to exchange new notes for the old notes. See "Use of
Proceeds" for a description of how we will use the proceeds of these offerings.

                         Summary of the Exchange Offer

   On July 14, 1999, we completed a private offering of the old notes. We
entered into a registration rights agreement with the initial purchasers in the
private offering in which we agreed to deliver to you this prospectus and to
complete the exchange offer within 210 days after the date we issued the old
notes.

Exchange Offer..........  We are offering to exchange new notes for old notes.

Expiration Date.........  The exchange offer will expire at 5:00 p.m. New York
                          City time, on       , 1999, unless we decide to
                          extend it.

Condition to the
 Exchange Offer.........  The registration rights agreement does not require us
                          to accept old notes for exchange if the exchange
                          offer or the making of any exchange by a holder of
                          the old notes would violate any applicable law or
                          interpretation of the staff of the Securities and
                          Exchange Commission. A minimum aggregate principal
                          amount of old notes being tendered is not a condition
                          to the exchange offer.

Procedures for
 Tendering Old Notes....  To participate in the exchange offer, you must
                          complete, sign and date the letter of transmittal, or
                          a facsimile of the letter of transmittal, and
                          transmit it together with all other documents
                          required by the letter of transmittal, including the
                          old notes that you wish to exchange, to Bankers Trust
                          Company, as exchange agent, at the address indicated
                          on the cover page of the letter of transmittal. In
                          the alternative, you can tender your old notes by

                          acceptance of old notes, we will accept any and all
                          old notes that you properly tender in the exchange
                          offer on or before 5:00 p.m. New York City time on
                          the expiration date. We will return any old note that

                          as promptly as practicable after the expiration date.
                          We will deliver the new notes as promptly as
                          practicable after the expiration date and acceptance
                          of the old notes for exchange. Please refer to the
                          section in this prospectus entitled "Exchange Offer--
                          Terms of the Exchange Offer."

Fees and Expenses.......  We will bear all expenses related to the exchange
                          offer. Please refer to the section in this prospectus
                          entitled "Exchange Offer--Fees and Expenses."

Use of Proceeds.........  The issuance of the new notes will not provide us
                          with any new proceeds. We are making this exchange
                          offer solely to satisfy our obligations under our
                          registration rights agreement. Please refer to the
                          sections entitled "Use of Proceeds" and "Management's
                          Discussion and Analysis of Financial Condition and
                          Results of Operations--Liquidity and Capital
                          Resources" for a discussion of our use of the
                          proceeds from the issuance of the old notes.

 Consequences of Failure
 to Exchange Old
 Notes..................  If you do not exchange your old notes in this
                          exchange offer, you will no longer be able to require
                          us to register the old notes under the Securities Act
                          of 1933 except in the limited circumstances provided
                          under our registration rights agreement. In addition,
                          you will not be able to resell, offer to resell or
                          otherwise transfer the old notes unless we have
                          registered the old notes under the Securities Act of
                          1933, or unless you resell, offer to resell or
                          otherwise transfer them under an exemption from the
                          registration requirements of, or in a transaction not
                          subject to, the Securities Act of 1933. Please refer
                          to the section in this prospectus entitled "Risk
                          Factors--Failure to Properly Tender Old Notes in
                          Exchange Offer."

U.S. Federal Income Tax
 Considerations.........  The exchange of new notes for old notes in the
                          exchange offer will not be a taxable event for U.S.
                          federal income tax purposes. Please read "Certain
                          Income Tax Considerations" on page 131.

Exchange Agent..........  We have appointed Bankers Trust Company as exchange
                          agent for the exchange offer. You should direct
                          questions and requests for assistance, requests for

                       Summary of Terms of the New Notes

   The new notes will be identical to the old notes except that the new notes
are registered under the Securities Act of 1933 and will not have restrictions
on transfer, registration rights or provisions for additional interest and will
contain different administrative terms. The new notes will evidence the same
debt as the old notes, and the same indenture will govern the new notes and the
old notes.

   The summary below describes the principal terms of the new notes. There are
important limitations and exceptions to the terms and conditions described
below. You should read the discussion under the heading "Description of the New
Notes" beginning on page 80 for further information regarding the new notes.
References in this summary of terms of the new notes to "we" and "our" refer
only to GlobeNet Communications Group Limited and do not include our
subsidiaries.

Issuer..................  GlobeNet Communications Group Limited.

Notes Offered...........  $300,000,000 principal amount of 13% Series B Senior
                          Notes due 2007.

Maturity................  July 15, 2007.

Interest................  Interest will accrue from July 14, 1999 or from the
                          most recent date to which we have paid interest on
                          the old notes, and will be payable on January 15 and
                          July 15, beginning on January 15, 2000.

Ranking.................  The new notes are our senior obligations and will
                          rank equally with all of our existing and future
                          senior indebtedness, and will be senior to all of our
                          existing and future subordinated indebtedness. The
                          new notes will effectively rank behind all of our
                          secured obligations to the extent of the value of the
                          assets securing these obligations.

                          We are a holding company and none of our subsidiaries
                          will guarantee the new notes. The new notes will
                          effectively rank behind all existing and future
                          indebtedness and all other liabilities of our
                          subsidiaries, including up to $450 million of
                          indebtedness under Holdings' bank credit facility.

Optional Redemption.....  We may redeem some or all of the new notes at any
                          time after July 15, 2004 at the redemption prices
                          listed under the heading "Description of the New
                          Notes--Optional Redemption," plus accrued and unpaid
                          interest, if any, to the redemption date.

Optional Redemption
 After Certain Equity
 Offerings..............  At any time prior to July 15, 2002, we may redeem up
                          to 35% of the notes that we originally issued under
                          the indenture with funds that we raise in one or more
                          equity offerings at 113% of the principal amount of
                          the redeemed notes, plus accrued and unpaid interest,
                          as long as at least 65% of the aggregate principal
                          amount of the notes originally issued remains
                          outstanding after each redemption. See "Description
                          of the New Notes--Optional Redemption."

Optional Tax
 Redemption.............  We may redeem all, but not fewer than all, of the new
                          notes at their principal amount, plus accrued and
                          unpaid interest, in the event of certain changes
                          affecting tax laws, as described under "Description
                          of the New Notes--Optional Tax Redemption."

Change of Control....... If a change of control of the Company occurs, we must
                         give holders of the new notes the opportunity to sell
                         us their new notes at the price set forth under the
                         heading "Description of the New Notes--Change of
                         Control." We might not be able to repurchase the
                         notes that you present following a change of control
                         because:


                             . we might not have enough funds at that time,
                               and

                             . the terms of our indebtedness or the
                               indebtedness of our subsidiaries may prevent
                               us.

Certain Indenture
 Provisions............. The indenture governing the new notes will contain
                         covenants limiting our ability and the ability of our
                         subsidiaries to:

                             . incur additional debt,

                             . pay dividends or distributions on our capital
                               stock or repurchase our capital stock,

                             . issue or sell capital stock of subsidiaries,

                             . make certain investments,

                             . sell assets,

                             . guarantee debt,

                             . restrict dividends or other payments to us,

                             . create certain liens,

                             . enter into transactions with affiliates, and

                             . merge, amalgamate, consolidate or sell
                               substantially all of our assets.

                          There are a number of important limitations and
                          exceptions to these covenants that are described
                          under the heading "Description of the New Notes" and
                          in the indenture.

                          Our failure to comply with these and the other
                          covenants under the indenture, a default in the
                          payment of any interest on or the principal of the
                          new notes, certain defaults on other indebtedness,
                          certain events relating to our bankruptcy and other
                          customary events may constitute events of default
                          under the indenture. The indenture requires us to
                          provide annual certificates to the trustee of our
                          compliance with the indenture and to otherwise notify
                          the trustee of defaults within 10 days of becoming
                          aware of the default.

Trustee.................  The trustee under the indenture is Bankers Trust
                          Company.

Listing.................  We do not intend to apply for listing of the new
                          notes on any securities exchange or for quotation of
                          the new notes in any automated dealer quotation
                          system.

                                  Risk Factors

   You should carefully consider the risk factors beginning on page 10 of this
prospectus before participating in the exchange offer.

                      Summary Consolidated Financial Data

   The following table sets forth summary consolidated financial data for the
Company. We have derived the summary consolidated statement of operations data
for the fiscal years ended December 31, 1998 and 1997 and for the ten months
ended December 31, 1996 for the Company from our consolidated financial
statements that PricewaterhouseCoopers, Chartered Accountants, has audited. We
have prepared the summary consolidated statement of operations data in
accordance with accounting principles generally accepted in the United States.
We have derived the summary consolidated financial data as at and for the six
months ended June 30, 1999 and June 30, 1998 from our unaudited interim
consolidated financial statements for these periods and we have prepared this
financial data on the same basis as the audited consolidated financial
statements. In the opinion of management, this financial data contains all
adjustments necessary for the fair statement of the results of operations for
these periods. Operating results for these six-month periods are not
necessarily indicative of the results of operations for a full year.

   We are substantially increasing the scope and scale of our business with the
development of the Atlantica-1 Network. Accordingly, the summary consolidated
financial data presented below may not be indicative of our financial position
or results of operations in the future. You should read the summary
consolidated financial data in conjunction with our consolidated financial
statements and the notes thereto that are included elsewhere in this
prospectus. See also "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

(1) Accrued contingent interest represents the payment that we would have had
    to make if the warrant holders had not exercised the warrants that we
    issued in connection with subordinated loans to TBI by July 28, 2002. We
    calculated it at 7% per annum on the gross exercise price for the
    unexercised warrants from the date of issue to the date of expiration. See
    note 9(c) to our audited consolidated financial statements.

(2) Earnings were inadequate to cover fixed charges and accordingly the
    deficiency of earnings available to cover fixed charges is as follows:
    $3,246 for the ten months ended December 31, 1996, $5,243 for the year
    ended December 31, 1997, $4,908 for the year ended December 31, 1998,
    $3,762 for the six months ended June 30, 1998, $1,037 for the six months
    ended June 30, 1999, $42,587 for the pro forma year ended December 31, 1998
    and $19,994 for the pro forma six months ended June 30, 1999. For the
    purposes of calculating the deficiency of earnings available to cover fixed
    charges, earnings consists of earnings (loss) before income taxes, minority
    interest and equity accounted for investment adjusted for minority
    interest, earnings (loss) from equity accounted for investment and the
    interest component of rental expense, and fixed charges consists of
    interest on long-term debt, amortization of deferred financing costs,
    accrued contingent interest and the interest component of rental expense.

(3) Earnings (loss) before interest, amortization, income taxes, minority
    interest and equity accounted for investment is not a measure of
    performance under U.S. GAAP, but we present it because we believe it is a
    measure of performance that analysts, investors and other interested
    parties in our industry commonly report and widely use. You should not
    consider it an alternative to net loss as a measure of operating
    performance or cash provided by (used in) operations as a measure of
    liquidity.

(4) As Adjusted column reflects the private offering of the old notes, the
    private equity financing and the exercise of warrants by our former
    subordinated lenders, and our use of the net proceeds therefrom, our
    payment of interest on one of our retired subordinated loans and the
    conversion of interest on the other subordinated loan, our repurchase of
    common shares of the Company from existing shareholders, our repayment of
    TBI's credit facility and related interest, transaction costs, accrued
    contingent interest and existing deferred financing costs. See
    "Capitalization."
(5) Does not include any borrowings of up to $450 million under Holdings' bank
    credit facility. Availability of these funds is subject to certain terms
    and conditions. See "Holdings' Bank Credit Facility."

                                  RISK FACTORS

   Before you tender the old notes in the exchange offer, you should carefully
consider the following risk factors and the other information in this
prospectus. The risks that we have described below are not the only ones facing
us. This prospectus also contains forward-looking statements that involve risks
and uncertainties. See "Forward-Looking Statements." Our actual results could
differ materially from those anticipated in the forward-looking statements as a
result of certain factors, including the risks described below and elsewhere in
this prospectus.

Risk Factors Relating to the Notes

 Failure to Properly Tender Old Notes in Exchange Offer--If you do not properly
 tender your old notes, you will continue to hold unregistered old notes and
 your ability to transfer old notes will be adversely affected.

   We will only issue new notes in exchange for old notes that are timely and
properly tendered. Therefore, you should allow sufficient time to ensure timely
delivery of the old notes and you should carefully follow the instructions on
how to tender your old notes. Neither we nor the exchange agent are required to
tell you of any defects or irregularities with respect to your tender of old
notes.

   If you do not exchange your old notes for new notes pursuant to the exchange
offer, the old notes you hold will continue to be subject to the existing
transfer restrictions. In general, the old notes may not be offered or sold
except under an exemption from, or in a transaction not subject to, the
Securities Act of 1933 and applicable state securities laws. We do not plan to
register old notes under the Securities Act of 1933. Further, if you continue
to hold any old notes after the exchange offer is consummated, you may have
trouble selling them because there will be fewer old notes outstanding.

 No Prior Market for the New Notes--If an active trading market does not
 develop for the new notes, you may be unable to sell the new notes or to sell
 the new notes at a price that you deem sufficient.

   The new notes will be new securities for which there currently is no
established trading market. Although the new notes will be registered under the
Securities Act of 1933, we do not intend to apply for listing of the new notes
on any securities exchange or for quotation of the new notes in any automated
dealer quotation system (including The PORTAL Market). In addition, although
the initial purchasers of the old notes have informed us that they intend to
make a market in the new notes after the exchange offer, the initial purchasers
may stop making a market at any time. Finally, if a large number of old notes
are not tendered or are tendered improperly, the limited amount of new notes
that would be issued and outstanding after we consummate the exchange offer
could adversely affect the development of a market for these new notes.

 Substantial Price Volatility--Even if a market for the new notes develops, the
 market price may be subject to substantial volatility.

   If a market for the new notes were to develop, the market price for the new
notes may be adversely affected by changes in our financial performance,
changes in the overall market for similar securities and the performance or
prospects for companies in our industry. Historically, the market for non-
investment grade debt has been subject to disruptions that have caused
substantial volatility in the prices of securities similar to the new notes.

 Substantial Leverage--Our substantial indebtedness could prevent us from
 fulfilling our obligations under the new notes and limit our ability to manage
 our business effectively.

   We have substantial debt and debt service requirements. As of September 30,
1999, we had consolidated indebtedness of approximately $400 million. Our
subsidiary Holdings may be able to borrow up to an additional $350 million
under its credit facility. Further, the indenture pursuant to which the notes
are issued and Holdings' bank credit facility may permit us to incur additional
debt, including secured debt, subject to

                                       10
<PAGE>


certain limitations. See "Description of the New Notes--Certain Covenants--
Incurrence of Indebtedness and Issuance of Preferred Stock" and "Holdings'
Bank Credit Facility."

   The amount of our debt could have important consequences to you. For
example, it could:

  . make it more difficult for us to satisfy our obligations with respect to
    the notes,

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

  . limit our ability to fund future capital expenditures, research and
    development costs, working capital and other general corporate
    requirements,

  . require us to dedicate a substantial portion of our cash flow from
    operations to make interest and principal payments on our indebtedness,

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

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

 Ability to Service Debt--If we are unable to generate a significant amount of
 cash, we may be unable to service our debt, including the notes.

   Our ability to generate sufficient cash flow to pay the principal of and
interest on our debt, including the notes, depends upon the successful and
timely completion of our systems, including the Atlantica-1 Network, the
successful and timely acquisition of terrestrial extensions, our future
operating performance and a number of other factors, many of which are beyond
our control.

   If we are unable to generate sufficient cash flow to meet our debt service
requirements, we may have to obtain additional debt or equity financing,
refinance or restructure all or a portion of our existing debt or sell all or
a portion of our assets. Our ability to take any of these actions will depend
on our financial condition at the time and other factors, including general
market and economic conditions. See "--Covenant Restrictions" below for a
description of certain restrictions in the agreements governing our debt that
could limit our ability to take any of these actions. Accordingly, these
transactions may not be possible. If, for any reason, including a shortfall in
anticipated cash flow, we are unable to meet our debt service obligations, we
would be in default under our existing debt agreements.

 Holding Company Structure--If our subsidiaries are unable to distribute funds
 to us, we will be unable to make payments on the notes.

   We are a holding company. Our only material asset is our ownership of the
capital stock of Holdings. As a result, our ability to make required payments
on the notes depends on the performance of the businesses owned by our
subsidiaries and our subsidiaries' ability to distribute funds to us. Our
subsidiaries will have no obligation to pay amounts due on the notes, and none
of our subsidiaries will guarantee the notes. In addition, the applicable law
of the jurisdictions in which these subsidiaries are organized or contractual
or other obligations to which they are subject may limit their ability to pay
dividends or make payments on intercompany loans, including those made with
the proceeds of the offering of the old notes.

   Holdings' bank credit facility and the related security, pledge, guarantee
and other documents will restrict our subsidiaries' ability to pay dividends,
make distributions or otherwise transfer funds to us. In addition, Holdings'
bank credit facility and these related instruments will prohibit Holdings from
making distributions to us from which we would otherwise expect to make
interest payments on the notes during the occurrence and continuance of
certain defaults or events of default under Holdings' bank credit facility and
the related instruments. See "Holdings' Bank Credit Facility."

   As of September 30, 1999, the notes were structurally subordinated to
approximately $100.0 million of debt of our subsidiaries. Our subsidiaries may
incur up to $350.0 million of additional debt under Holdings' bank credit
facility, and they may incur more debt in the future.

                                      11
<PAGE>


 Covenant Restrictions--Holdings' bank credit facility, the related security,
 pledge, guarantee and other documents and the indenture impose significant
 restrictions on our ability to take certain actions.

   These restrictions will significantly limit or prohibit, among other things,
our ability and our subsidiaries' ability to:

  . engage in unrelated business activities,

  . incur additional indebtedness,

  . repay indebtedness prior to stated maturities,

  . sell assets,

  . make investments,

  . engage in transactions with shareholders and affiliates,

  . issue capital stock,

  . create liens, or

  . engage in mergers, amalgamations or acquisitions.

   These restrictions could also limit our ability and our subsidiaries'
ability to:

  . obtain financing in the future,

  . make needed capital expenditures,

  . withstand a future downturn in our business or the economy in general, or

  . otherwise conduct necessary corporate activities.

   Events beyond our control, including prevailing economic and financial
conditions, may affect our ability and our subsidiaries' ability to comply with
these covenants and restrictions. If we or our subsidiaries fail to comply with
these restrictions, it could lead to a default under the terms of Holdings'
bank credit facility, the related security, pledge, guarantee and other
documents or the indenture notwithstanding our ability and the ability of our
subsidiaries to meet our respective debt service obligations.

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

   The indenture requires us, in the event of a change of control, to make an
offer to purchase the notes at a price equal to 101% of the principal amount of
the notes, plus accrued interest to the date of purchase. This provision may be
of limited value to holders of notes because, before making the offer to
purchase the notes, we would be required to (1) repay in full all of our
indebtedness under Holdings' bank credit facility and any other indebtedness
that would prohibit the purchase of the notes, or (2) obtain any requisite
consent to permit the purchase of the notes. We may not have sufficient funds
available at the time of any change of control to make any debt payment
(including purchase of the notes) as described above.

   The events that constitute a change of control under the indenture may also
be events of default under Holdings' bank credit facility. An event of default
under Holdings' bank credit facility may permit the lenders to accelerate the
outstanding debt under the credit facility and, if the debt is not repaid, to
foreclose on assets of our subsidiaries subject to security interests. This
would limit our ability to raise cash to purchase the new notes.

                                       12

Risk Factors Relating to the Company

 Limited Operating History--Because of our limited operating history and
 negative cash flow, an investment in the notes may be subject to greater risk
 than an investment in the securities of an entity with a longer operational
 history.

   We began providing telecommunications services in Bermuda in May 1997
through TBI. We have accumulated losses as of June 30, 1999 of $16.0 million
and have never earned a profit. In addition, our historical financial
information relates primarily to TBI's retail international telecommunications
business and not the international telecommunications network solutions
business we are entering with the construction of the Atlantica-1 Network.
Accordingly, you have very limited historical financial information upon which
to base your evaluation of our performance and an investment in the new notes.
You should consider our prospects in light of the risks, expenses and
difficulties frequently encountered by companies in an early stage of
development.

   We intend to use most of the proceeds from the sale of the old notes and a
significant amount of additional capital to develop the Atlantica-1 Network and
terrestrial extensions. Until the principal segments of the network are
complete, we will continue to spend more building the network than we will earn
from selling capacity on it. Accordingly, we expect to experience negative cash
flows after capital expenditures while we are developing our network. Our
future success will depend substantially on sales of capacity on the Atlantica-
1 Network and any subsequent systems. We may be unable to realize our business
plan, achieve operating profitability or generate sufficient cash flow to
service our debt (including the notes), capital expenditures or working capital
requirements.

 Substantial Future Capital Requirements--Our future growth will require
 substantial additional capital requirements that may exceed our budgeted
 amounts and for which we may need to incur additional indebtedness.

   Although we expect the net proceeds we received from the private offering of
the old notes, the net proceeds we received from the private equity financing
and future borrowings under Holdings' bank credit facility to be sufficient to
complete the development of the Atlantica-1 Network, we expect to need
significant amounts of additional capital to implement our business plan. In
addition to building the Atlantica-1 Network, we may in the future expand our
undersea fiber optic cable systems through the development of the Atlantica-2
Network. We expect the Atlantica-2 Network to have a comparable unit price per
kilometer to the Atlantica-1 Network and to require substantial capital to
develop.

   If we cannot generate sufficient funds from operations, we may issue
additional debt or equity capital. The provisions of the indenture, Holdings'
bank credit facility and the related security, pledge, guarantee and other
documents, however, may restrict our ability to issue debt or equity. We may be
unable to arrange financing in the future or, if we are able to do so, we may
be unable to arrange financing on terms that are favorable to us. Our ability
to arrange financing and the cost of the financing will depend on many factors
including:

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

  . conditions in the telecommunications industry,

  . regulatory developments,

  . investor confidence and credit availability from banks and other lenders,

  . the success of the Atlantica-1 Network, and

  . tax and securities laws that affect raising capital.

                                       13
<PAGE>


 Completion of the Atlantica-1 Network--If we fail to complete our network
 within our estimated cost and time-frame, we may be unable to provide our
 network services competitively.

   In order to implement our business strategy and generate cash flows to
service our indebtedness, we must successfully complete the Atlantica-1
Network at the cost and in the time-frame currently estimated by us. We have
entered into a contract with Alcatel to design, engineer and construct the
Atlantica-1 Network on a turnkey basis. The construction of the Atlantica-1
Network will be affected by a wide variety of factors, uncertainties and
contingencies, many of which are beyond our or Alcatel's control, including
inclement weather and adverse changes in government regulations. Alcatel also
may suspend its work on the network if we fail to make the requisite periodic
payments. Any suspension could result in a failure to meet a scheduled
completion date. In addition, our contract with Alcatel limits the damages
that we could recover in the event of a breach by Alcatel.

   There are few manufacturers of materials used to build undersea fiber optic
cable systems and these manufacturers have a limited capacity that is reserved
in advance. Alcatel has reserved capacity for the Atlantica-1 Network. A
significant delay in our time-frame could cause us to be unable to obtain the
manufacturing capacity necessary to complete the network.

   Our successful completion of the Atlantica-1 Network at the cost and in the
time-frame currently estimated by us will also depend, among other things,
upon our ability to manage its construction effectively and Alcatel's ability
to obtain all construction permits and licenses.

 Sales of Capacity--If we are unable to sell sufficient capacity on our cable
 systems or to sell capacity on favorable terms, then we may be unable to
 generate sufficient revenues and cash flows to implement our business plan or
 service our indebtedness.

   As of the date of this prospectus, we have only sold limited capacity on
the BUS-1 system and have not sold any capacity on the Atlantica-1 Network.
There may not be sufficient demand to support our network, we may not be able
to sell capacity on our cable systems and any sales may not be on favorable
terms. Two other competing undersea fiber optic cable systems have been
announced with capacity, technology and scheduled completion dates that are
expected to be similar to our network. These other systems may adversely
affect our ability to sell our capacity.

 Realization of Other Revenues--If we fail to increase our revenues beyond
 initial capacity sales, we may be unable to implement our business plan.

   We intend to increase our revenues and profits by:

  . upgrading capacity on the Atlantica-1 Network,

  . developing or acquiring additional undersea fiber optic cable capacity,

  . developing or purchasing terrestrial extensions in a cost effective
    manner to provide connectivity from landing stations to major city
    centers,

  . introducing new products and services such as value-added offerings
    through which a customer could use our Bermuda base of network operations
    to generate cost-savings and minimize income taxes, and

  . increasing TBI's market share in Bermuda through the introduction of
    innovative product and service offerings at competitive prices.

 Operations Risks--If our systems fail to operate properly or are damaged, we
 may be unable to provide our intended network services and to implement our
 business plan.

   Our success is dependent upon our systems providing competitive
reliability, capacity and security. The operation, administration, maintenance
and repair of a large-scale, complex telecommunications network, however,
requires the coordination and integration of sophisticated and highly
specialized hardware and

                                      14
<PAGE>


software technologies and equipment. The Atlantica-1 Network will employ
certain components that have never been used before in an undersea fiber optic
cable system. The BUS-1 system also is subject to operational risks. The
failure of the hardware or software to function as required could render an
undersea fiber optic cable system unable to perform at design specifications.
Even if built to specifications, our systems may not function as expected in a
cost-effective manner. Additional operational risks include physical damage,
power loss, capacity limitations, breaches of security and disruptions beyond
our control.

   We expect each of our systems to have a design life of not less than 25
years; however, the actual useful life of any of these systems may be shorter.
A number of factors will affect the useful life of each of our systems,
including, among other things:

  . quality of construction,

  . unexpected deterioration, and

  . technological or economic obsolescence.


 Competition--We may be unable to compete with our larger and better financed
 competitors.

   The international telecommunications industry is extremely competitive. We
face competition from existing and planned systems along each of our planned
routes. We will also compete with satellite providers and land-based cable
systems. Most of our competitors have substantially greater financial,
technical and marketing resources than we do. We will compete primarily on the
basis of price, availability, flexible provisioning, colocation services,
transmission quality and reliability, customer service and the locations our
systems connect.

   Future sources of competition for the Atlantica-1 Network include:

  . Americas-2, a new carriers' consortium cable system with a scheduled RFS
    date in the third quarter of 1999 that will connect Brazil, Venezuela,
    Florida and the Caribbean,

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

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

   Global Crossing Ltd. has stated that South American Crossing is scheduled to
be available for service in the first quarter of 2001 and will be capable of
providing up to 1,280 Gbps of total capacity. Telefonica Internacional S.A. and
Tyco International Ltd. have stated that SAm-1 is scheduled to be available for
service in December 2000 and will be capable of providing up to 1,280 Gbps of
total capacity. There may not be sufficient demand to support all of these
systems or additional systems that may be built.

   Our existing business, the provision of retail telecommunications services
in Bermuda, is also very competitive. Our only licensed competitor in this
market, Cable & Wireless, has:

  . substantially greater financial, technical and marketing resources,

  . access to larger networks through inter-company relationships,

  . a broader portfolio of services,

  . stronger name recognition, and

  . long-standing customer relationships.

                                       15
<PAGE>


   An Internet service provider in Bermuda has recently filed for declaratory
relief following the Bermuda Government's refusal to permit it to provide voice
over Internet service under the terms of its license. The Bermuda Government
may not prevail in the pending lawsuit, and other parties may become licensed
to provide long distance service in Bermuda. This may adversely impact our
revenues from TBI's Bermuda long distance business.

 Dependence on Senior Management--If we lose members of our senior management
 team, we may be unable to implement our business plan.

   We are dependent on the continued employment of our senior management team
in order to implement our business plan. Our business is managed by a small
number of key management and operating personnel who have been extensively
involved in our formation and the establishment of our key business
relationships. Among other things, we rely on specific individuals to supervise
the construction of our undersea cable network, to negotiate strategic
alliances with telecommunications service providers and other carriers, to sell
capacity on the network and to oversee and implement other aspects of our
business plan. The loss of any member of our management team could delay or
prevent us from achieving these aspects of our business plan. Competition for
management-level individuals in the telecommunications industry is intense, and
we may not be able to attract, motivate and retain highly skilled qualified
personnel. We do not maintain any key person life insurance on the lives of any
of our management personnel.

 Ability to Manage Growth--If we are unable to effectively manage our growth
 and transition from a development company to an operating company, we may not
 be successful in developing and operating our network.

   Our planned growth and expansion will place significant demands on our
management and operations. Our ability to manage this growth successfully will
depend on, among other things:

  . expanding our management resources, network infrastructure, information
    and reporting systems and controls,

  . expansion, training and management of our employee base, including
    attracting and retaining skilled personnel,

  . evaluating new markets,

  . monitoring operations,

  . controlling costs, and

  . obtaining satisfactory interconnection agreements with other network
    providers.

 Dependence on Third Parties--If the third parties upon whom we depend do not
 perform their contractual obligations, we will be unable to provide our
 network services.

   We and our customers depend and will continue to depend upon third parties,
such as carriers, Post, Telephone and Telegraph companies, or PTTs,
telecommunications facilities providers and suppliers, and local operating
companies, including the Bermuda Telephone Company, to:

  . construct and maintain systems and provide equipment,

  . provide access to certain origination and termination points of our
    systems in various jurisdictions,

  . construct and operate landing stations in certain of these jurisdictions,

  . acquire rights of way, licenses and permits, and

  . provide terrestrial capacity.

   These third parties may not perform their contractual obligations.

                                       16
<PAGE>


 Tax Matters--We have assumed that a significant portion of our income will
 not be subject to certain taxes. If our assumption is incorrect or if there
 are changes in the prevailing tax laws, it could adversely impact our
 revenues and our cash flow available to make payments on the notes.

   We believe that a significant portion of the income derived from our
undersea fiber optic systems will not be subject to tax by any of (1) Bermuda,
which currently does not have a corporate income tax, (2) Brazil, (3)
Venezuela, or (4) certain other countries in which we will conduct activities
or in which our target customers will be located, including the United States.
However, we base our belief upon the anticipated nature and conduct of our
business, which may change, and upon our understanding of the tax laws of the
various countries in which we expect to have assets or conduct activities. Our
position is subject to review and possible challenge by taxing authorities and
to possible changes in law, which may have retroactive effect. We cannot
predict the amount of tax to which we may become subject. For more
information, see "Certain Income Tax Considerations."

 Year 2000 Problem--If we experience system failures as a result of the Year
 2000 Problem, our ability to provide our network services may be adversely
 affected.

   The year 2000 problem is the result of many computer programs being written
using two digits rather than four to define the applicable year. Computer
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculations. If necessary modifications are not made, the year 2000
problem could adversely impact our ability to provide our telecommunications
services. Furthermore, the systems of other companies on which our systems
rely may not be prepared for the year 2000, or these companies may implement
year 2000 preparations with systems that are incompatible with our systems.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations--Year 2000 Problem."

 Significant Shareholders with Potentially Adverse Interests--Our significant
 shareholders may cause us to pursue transactions that increase the risk of
 your investment in the notes.

   The institutional investors named below or their affiliates purchased
approximately 67% of the common shares of the Company on a fully diluted basis
and Class B shares, which have certain voting rights as described under the
heading "Principal Shareholders--Capital Structure," in the private equity
financing:

  . Boston Ventures Management, Inc.,

  . Kelso & Company,

  . Providence Equity Partners, Inc.,

  . Spectrum Equity Investors,

  . TD Capital Group Limited (an affiliate of one of the initial purchasers
    of old notes),

  . Capital Communications CDPQ Inc.,

  . Sandler Capital Management,

  . Ontario Municipal Employee Retirement Board and

  . Nautilus Equity Investors LLC (whose managing member is an indirect
    subsidiary of one of the initial purchasers of old notes).

   There may be conflicts of interest between these investors and you if we
encounter financial difficulties or these investors cause us to pursue
transactions that could enhance their equity investment while involving risks
to your interests.

   Certain of these investors, or their affiliates, currently have significant
investments in other telecommunications companies, and may in the future
invest in other entities engaged in the telecommunications business, some of
which may compete with us. These investors have no obligation to bring

                                      17
<PAGE>

us any investment or business opportunities of which they are aware, even if
opportunities are within our scope and objectives. Conflicts may also arise in
the negotiation or enforcement of arrangements we may enter into with entities
in which these investors, or their affiliates, have an interest.

 Service of Process and Enforcement of Liabilities--It may be difficult for
 you to enforce U.S. judgments against our foreign assets, to serve our
 foreign officers and directors or to enforce U.S. judgments against them and
 to enforce U.S. securities laws in Bermuda.

   GlobeNet Communications Group Limited is a Bermuda company. A substantial
portion of our assets and our principal offices are located outside of the
United States. In addition, some of our directors and officers are not
residents of the United States. As a result, it may be difficult for you to
enforce judgments obtained in United States courts against our assets located
outside the United States, and it may be difficult for you to effect service
of process within the United States upon these directors and officers or to
enforce judgments obtained in United States courts against them. Furthermore,
our legal counsel in Bermuda, Conyers Dill & Pearman, has advised us that
there is doubt as to the enforcement in Bermuda, in original actions or in
actions for enforcement of judgments of United States courts, of liabilities
predicated upon U.S. securities laws.

Risk Factors Relating to the Industry

 Demand for Fiber Optic Capacity--If fiber optic cable technology becomes
 obsolete or is replaced by newer competing technologies, we may be unable to
 implement our business plan.

   The international telecommunications industry is changing rapidly due to,
among other things:

  . the easing of regulatory constraints,

  . the privatization of established carriers and PTTs,

  . the expansion of telecommunications infrastructure,

  . economic globalization, and

  . the changing technology for all telecommunications industry sectors,
    including cable, wireless and satellite.

   Our business strategy and much of our planned growth is predicated upon the
continuation of the growth in demand for international telecommunications
capacity that has occurred over the past several decades and the continued
viability of fiber optic cable networks as a preferred means of transmitting
voice and data. This may not occur.

 Declining Prices Per Circuit--If there is a bigger decline in prices for
 circuits than we expect, we may not generate sufficient revenues to implement
 our business plan.

   The fiber optic cable transmission industry has realized significant per
unit cost reductions over the past several years resulting from technological
advances in fiber optics. These advances have caused prices for circuits 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:

  . price competition as various network providers continue to install
    networks that might compete with the Atlantica-1 Network,

  . recent technological advances that result in substantial increases in the
    transmission capacity of both new and, to a lesser extent, existing fiber
    optic telecommunications networks, and

  . strategic alliances or similar transactions, such as long-distance
    capacity purchasing alliances among groups of carriers, that could
    increase the parties' purchasing power.

   There may, however, be a bigger decline in prices per circuit than we
expect.

                                      18
<PAGE>


 Risks Associated with International Markets--We will operate in many foreign
 markets and will be exposed to risks in those markets that may prevent us from
 providing our network services or may adversely affect our ability to do so
 profitably.

   We will be exposed to certain risks inherent in doing business on an
international level. These risks include:

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

  . unexpected changes in regulatory requirements, tariffs, customs, duties
    and other trade barriers,

  . difficulties in staffing and managing foreign operations,

  . political risks,

  . fluctuations in currency exchange rates and restrictions on repatriation
    of earnings, and other exchange control regulations,

  . delays from customers, brokers or government agencies,

  . potentially adverse tax consequences resulting from operating in multiple
    jurisdictions with different tax laws, and

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

 Government Regulation--We and our customers are subject to substantial
 government regulation in the United States and several other jurisdictions.
 These regulations may affect our ability to operate our systems or offer
 certain of our products.

   We may, in the ordinary course of development, construction and operation of
our network, be required to obtain and maintain various permits, licenses and
other authorizations including undersea cable landing licenses (and
environmental and natural resources licenses or permits) in the United States,
Brazil, Bermuda, Venezuela and in any other foreign jurisdictions where our
cables may land and exist. If we are unable to obtain and maintain necessary
permits, licenses and other authorizations, we will be unable to operate our
systems.

   United States: On June 2, 1999 we submitted a submarine cable landing
license application to the Federal Communications Commission ("FCC") in the
United States. No comments or objections were filed with the FCC in response to
this application. While we expect to receive a landing license by the end of
1999, the FCC may not grant us a landing license or it may not do so within our
time schedule. We cannot complete the Atlantica-1 Network without a landing
license for the United States. See "Business--Regulation--United States."

   Brazil: We have submitted a written request to the Agencia Nacional de
Telecomunicacoes, or ANATEL, the telecommunications regulatory authority in
Brazil, seeking a determination as to the scope and nature of ANATEL's
authority to regulate undersea cable systems such as the Atlantica-1 Network.
ANATEL may determine that no regulatory authority is necessary to construct,
own and operate the Atlantica-1 Network or merely grant us an enabling act that
permits us to land the cable or require us to register the cable with ANATEL.
If ANATEL were to determine, however, that the offering of undersea cable
facilities is providing telecommunications services, and regulates us
accordingly, it would subject us to certain taxes and operational restrictions
that may adversely affect our ability to implement our business plan. We may
not be able to complete the Atlantica-1 Network unless ANATEL informs us
whether its approval is necessary to land an undersea cable in Brazil. If
ANATEL determines that it must provide us authority before we can land the
cable, we will need to take appropriate action to procure this authority.
Failure to obtain this authority or a delay in the grant of the authority could
prevent us from providing our intended network services.

   Venezuela: We have received written confirmation from the Comision Nacional
de Telecomunicaciones, or CONATEL, the telecommunications regulatory agency in
Venezuela, that we may construct and land the Atlantica-1 cable in Venezuela
without formal regulatory approval from CONATEL. Additionally, based on

                                       19
<PAGE>


advice provided to us by CONATEL, we do not believe that any CONATEL permits or
concessions are necessary to operate the cable or sell capacity on the cable.
However, if CONATEL were now to determine that a permit or concession was
necessary, we believe that a permit or concession would be issued by CONATEL in
a time frame consistent with the implementation schedule for the Atlantica-1
Network. Our inability to secure any necessary approvals in the required time
frame could prevent us from providing our intended network services.

   We intend to submit to CONATEL an application for the appropriate licenses
that will permit us to provide backhaul services in Venezuela. While we expect
CONATEL to grant us these licenses, CONATEL may not do so, or it may not do so
within our time schedule.

   Bermuda: On January 10, 1997, the government of Bermuda granted TBI an
international carrier license. The license is for a term of five years and is
subject to renewal. The government may not renew our license. If the government
fails to renew our license, we will no longer be able to provide
telecommunications services in Bermuda and will be required to sell TBI's
telecommunications business.

                        FORWARD-LOOKING STATEMENTS

   This prospectus includes forward-looking statements. We use words like
"believe," "anticipate," "expect," "estimate," "may," "will," "should" and
similar expressions to help identify these forward-looking statements. Forward-
looking statements contained in this prospectus include, for example,
statements concerning our plans to design, construct, operate and sell capacity
on our planned cable systems, expectations as to funding our future capital
requirements, developments with respect to regulatory and market conditions and
other discussions of future plans and strategies, anticipated developments and
other matters that involve predictions of future events.

   We have based these forward-looking statements on our current expectations
and projections about future events. These forward-looking statements are
subject to risks and uncertainties, some of which may be outside of our
control, including, among other things:

  .  our failure to complete our planned cable systems within the currently
     estimated time frame and budget,

  .  our failure to be early to market,

  .  our failure to sell capacity on our planned cable systems,

  .  our failure to obtain and maintain all necessary permits, licenses or
     authorizations to construct, land and operate our planned cable systems,

  .  our failure to contract for or build any necessary backhaul facilities
     to provide city-to-city connectivity on our planned cable systems,

  .  our failure to accurately project levels of demand for
     telecommunications capacity,

  .  political, economic, legal or regulatory changes that negatively affect
     our operations, and

  .  our failure to compete effectively in a rapidly evolving marketplace
     characterized by intense price competition and incremental new capacity.

   This list is only an example of some of the risks, uncertainties and
assumptions that may affect the forward-looking statements contained in this
prospectus. In light of these and other risks, uncertainties or assumptions,
the actual events or results may be very different from those expressed or
implied in the forward-looking statements in this prospectus or may not occur.
For additional factors that could affect the validity of our forward-looking
statements, you should carefully consider the risk factors beginning on page 10
and the other information in this prospectus. We do not intend to publish
updates or revisions of any forward-looking statement to reflect new
information, future events or otherwise.

                                USE OF PROCEEDS

New Notes

   We will not receive any proceeds from the issuance of the new notes. We are
making this exchange offer solely to satisfy our obligations under our
registration rights agreement.

Financing Plan

   We estimate that the total cost to build the Atlantica-1 Network, including
the secondary strand of the Rio extension, the Caracas extension, landing
stations and capital contingencies, will be approximately $825 million. This
estimate does not include potential costs, if any, associated with securing
terrestrial capacity, including any terrestrial extension to Buenos Aires,
Argentina.

   As more fully described below, we have used and intend to use the net
proceeds we received from the private offering of the old notes, the net
proceeds we received from the private equity financing (other than the

                                       21
<PAGE>

proceeds that we used to repurchase common shares of the Company from existing
shareholders), the net proceeds from the exercise of warrants by our former
subordinated lenders, and availability under Holdings' bank credit facility to
fund:

  . the cost to build the Atlantica-1 Network, including the secondary strand
    of the Rio extension, the Caracas extension, landing stations and capital
    contingencies,

  . the repayment of our subordinated loans and TBI's credit facility,

  . transaction costs,

  . pre-RFS working capital requirements, and

  . costs, if any, associated with our initial requirements for terrestrial
    capacity.

   As of September 30, 1999, we have spent approximately $103.0 million of
these funds to make an initial payment under our contract with Alcatel, to pay
certain interest on our subordinated loans, to repay TBI's credit facility, to
pay transaction costs, to pay commitment fees on Holdings' bank credit facility
and to pay working capital requirements.

 Private Offering of Old Notes

   On July 14, 1999, we issued $300 million in aggregate principal amount of
old notes to the initial purchasers in an offering exempt from the registration
requirements of the Securities Act of 1933. The net proceeds we received from
this offering were approximately $288.9 million.

 Private Equity Financing

   On July 14, 1999, we received approximately $270.6 million from various
institutional investors in exchange for 13,263,646 newly issued common shares
that represent approximately 67% of our common shares on a fully diluted basis
and 1,000 Class B shares, which have special voting rights.

   On August 9, 1999, we accepted for repurchase 1,500,000 common shares held
by existing shareholders at $20.40 per share (less expenses) for an aggregate
price of $30.6 million. This repurchase price was paid out of a portion of the
proceeds of the private equity financing.

   In connection with this private equity financing, our former subordinated
lenders, one of whom is an indirect affiliate of one of the initial purchasers
of old notes and a subsidiary of TD Capital Group Limited, a shareholder of the
Company, exercised the warrants they obtained when they made subordinated loans
to us. The effect of this exercise was to convert the principal amount of their
$13.5 million of subordinated loans and, in the case of one of these lenders,
$1.9 million of accrued interest, into 1,635,286 common shares of the Company.
We paid accrued interest of $0.9 million owed to the other subordinated lender
out of the net proceeds of the private offering of the old notes and the
private equity financing, thus retiring the subordinated loans. One of the
subordinated lenders also acquired all of the common shares, Class A shares and
TBI Class A shares held by the other subordinated lender. The outstanding Class
A shares of the Company and TBI were then cancelled.

 Holdings' Bank Credit Facility

   On July 14, 1999, our subsidiary Holdings entered into a credit agreement
with Toronto Dominion (Texas) Inc., Credit Suisse First Boston, and TD
Securities (USA) Inc. pursuant to which, subject to certain terms and
conditions, Holdings may borrow up to $400 million and may request an
additional facility for up to $50 million. As of September 30, 1999, Holdings
had borrowed $100 million under this credit facility. See "Holdings' Bank
Credit Facility."

        UNAUDITED CONDENSED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

   The following condensed unaudited pro forma consolidated financial
information of the Company has been derived by the application of pro forma
adjustments to the Company's historical consolidated financial statements for
the year ended December 31, 1998 and for the six-month period ended June 30,
1999. The unaudited condensed pro forma consolidated balance sheet gives effect
to the private equity financing, the issuance of the notes, the application of
the proceeds therefrom and the other transactions described in the accompanying
notes as if they occurred on June 30, 1999. The unaudited condensed pro forma
consolidated statement of operations for the year ended December 31, 1998, and
for the six month period ended June 30, 1999, give effect to the transactions
as if they had occurred as of January 1, 1998.

   The pro forma adjustments presented are based upon available information and
certain assumptions that we believe are reasonable under the circumstances.
These adjustments are directly attributable to the transactions referenced
above and are expected to have a continuing impact on our business, results of
operations and financial condition. Interest related to the debt issuance has
been expensed in this pro forma financial information. However, an element of
this interest will be capitalized during the time that the Atlantica-1 Network
is under construction. The amount to be capitalized is not readily determinable
at this time. The unaudited condensed pro forma consolidated balance sheet as
of June 30, 1999 and unaudited condensed pro forma statement of operations for
the six-month period ended June 30, 1999 were derived from the unaudited
consolidated financial statements included elsewhere in this prospectus. The
unaudited condensed pro forma consolidated statement of operations for the year
ended December 31, 1998 was derived from the audited consolidated financial
statements included elsewhere in this prospectus.

   The unaudited condensed pro forma financial information should be read in
conjunction with the historical consolidated financial statements of the
Company and the notes thereto and "Management's Discussion and Analysis of
Financial Condition and Results of Operations," included elsewhere in this
prospectus.

   The unaudited condensed pro forma financial information and related notes
are provided for informational purposes only and do not necessarily reflect the
results of operations or financial condition of the Company that would have
actually resulted had the events referred to above or in the notes to the
unaudited condensed pro forma financial information been consummated as of the
dates indicated and are not intended to project the Company's financial
condition or results of operations for any future period.

  NOTES TO UNAUDITED CONDENSED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS

   This presentation does not reflect the capitalization of interest related to
   the Atlantica-1 Network. An element of this interest will be capitalized
   during the time that the Atlantica-1 Network is under construction.

(2)  Reflects the amortization of the deferred transaction fees and expenses in
     relation to the 13% Senior Notes due 2007 and Holdings' bank credit
     facility and the elimination of the amortization costs related to the
     existing deferred financing costs, as follows:

      Amortization related to the 13% Senior Notes due 2007 and
       Holdings' bank credit facility...............................  $  1,673
      Amortization expense related to the existing deferred
       financing costs..............................................      (160)
                                                                      --------

(3)  Reflects the accrued contingent interest in connection with the exercise
     of the warrants on the subordinated loans.

(4) On April 12, 1999, we granted 540,000 options at an exercise price of $9.00
    with a ten-year term to certain directors and officers. These options vest
    in three separate tranches subject to the Company meeting certain
    milestones related to the Atlantica-1 Network. The first vesting milestone
    on 515,000 of these options occurred on July 14, 1999 when the financing
    for the Atlantica-1 Network was obtained. The difference between the
    exercise price and the market value of the shares at the time of vesting
    will be reflected as compensation expense. This compensation expense has
    not been reflected as an adjustment in this condensed pro forma
    consolidated statement of operations as the first traunch of these options
    did not vest until July 14, 1999.

(3) Reflects the accrued contingent interest in connection with the exercise of
    the warrants on the subordinated loans.

(4) On April 12, 1999, we granted 540,000 options at an exercise price of $9.00
    with a ten-year term to certain directors and officers. These options vest
    in three separate tranches subject to the Company meeting certain
    milestones related to the Atlantica-1 Network. The first vesting milestone
    on 515,000 of these options occurred on July 14, 1999 when the financing
    for the Atlantica-1 Network was obtained. The difference between the
    exercise price and the market value of the shares at the time of vesting
    will be reflected as compensation expense. This compensation expense has
    not been reflected as an adjustment in this condensed pro forma
    consolidated statement of operations as the first traunch of these options
    did not vest until July 14, 1999.

                      SELECTED CONSOLIDATED FINANCIAL DATA

   The following table sets forth selected consolidated financial data for the
Company. We have derived the selected consolidated statement of operations data
for the fiscal years ended December 31, 1998 and 1997 and for the ten months
ended December 31, 1996 and the selected consolidated balance sheet data as at
December 31, 1998, 1997 and 1996 from our consolidated financial statements
that PricewaterhouseCoopers, Chartered Accountants, has audited. We have
prepared this selected consolidated statement of operations data and balance
sheet data in accordance with accounting principles generally accepted in the
United States. We have derived the selected consolidated financial data as at
and for the six months ended June 30, 1999 and June 30, 1998 from our unaudited
interim consolidated financial statements for these periods and we have
prepared this financial data on the same basis as the audited consolidated
financial statements. In the opinion of management, this financial data
contains all adjustments necessary for the fair statement of the results of
operations for these periods. Operating results for these six-month periods are
not necessarily indicative of the results of operations for a full year.

   We are substantially increasing the scope and scale of our business with the
development of the Atlantica-1 Network. Accordingly, the selected consolidated
financial data presented below may not be indicative of our financial position
or results of operations in the future. You should read the selected
consolidated financial data in conjunction with our consolidated financial
statements and the notes thereto that are included elsewhere in this
prospectus. See also "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

(1) Accrued contingent interest represents the payment that we would have had
    to make if the warrant holders had not exercised the warrants that we
    issued in connection with our retired subordinated loans by July 28, 2002.
    We calculated it at 7% per annum on the gross exercise price for the
    unexercised warrants from the date of issue to the date of expiration. See
    note 9(c) to our audited consolidated financial statements.

(2) Earnings were inadequate to cover fixed charges and accordingly the
    deficiency of earnings available to cover fixed charges is as follows:
    $3,246 for the ten months ended December 31, 1996, $5,243 for the year
    ended December 31, 1997, $4,908 for the year ended December 31, 1998,
    $3,762 for the six months ended June 30, 1998, $1,037 for the six months
    ended June 30, 1999, $42,587 for the pro forma year ended December 31, 1998
    and $19,994 for the pro forma six months ended June 30, 1999. For the
    purposes of calculating the deficiency of earnings available to cover fixed
    charges, earnings consists of earnings (loss) before income taxes, minority
    interest and equity accounted for investment adjusted for minority
    interest, earnings (loss) from equity accounted for investment and the
    interest component of rental expense, and fixed charges consists of
    interest on long-term debt, amortization of deferred financing costs,
    accrued contingent interest and the interest component of rental expense.

(3) Earnings (loss) before interest, amortization, income taxes, minority
    interest and equity accounted for investment is not a measure of
    performance under U.S. GAAP, but we present it because we believe it is a
    measure of performance that analysts, investors and other interested
    parties in our industry commonly report and widely use. You should not
    consider it an alternative to net loss as a measure of operating
    performance or cash provided by (used in) operations as a measure of
    liquidity.

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

   You should read the discussion under this caption in conjunction with our
audited consolidated financial statements and unaudited interim consolidated
financial statements and the notes thereto included elsewhere in this
prospectus. Certain information contained in this section, including
information with respect to our plans and expectations for our business, is
forward-looking. You should carefully consider the factors set forth under the
captions "Forward-Looking Statements" and "Risk Factors" for a discussion of
important factors that could cause actual results to differ materially from any
forward-looking statements contained in this prospectus.

Overview

   GlobeNet Communications Group Limited was incorporated and registered on
June 25, 1998 as a Bermuda exempt company as part of a reorganization of the
TBI group of companies. Under the reorganization, TBI, which was incorporated
on January 6, 1995, became our wholly owned subsidiary, and the issued shares
of TBI were exchanged for our common shares on a one-for-one basis with
substantially the same rights and privileges.

   Historically, through our wholly owned subsidiary TBI, we have provided
retail international telecommunications services to, from and through Bermuda.
We plan to extend our business to become a provider of city-to-city
international telecommunications network solutions on a wholesale "carriers'
carrier" basis using a combination of undersea fiber optic cable systems and
terrestrial extensions. We are currently developing the Atlantica-1 Network, an
undersea fiber optic cable system, as part of this plan.

   Our international telecommunications network solutions business is in the
development stage and, accordingly, our historical consolidated financial
information relates primarily to TBI's retail international telecommunications
business and is not necessarily indicative of future results.

   We report our results in U.S. dollars, although historically a significant
portion of our revenues and expenses have been settled in Bermuda dollars,
which are pegged to the U.S. dollar at par. Therefore, currency fluctuations
have not affected the results of our existing operations. Substantially all of
our costs incurred in connection with the Atlantica-1 Network will be incurred
in U.S. dollars. While we expect to invoice a majority of our customers in U.S.
dollars, we may be required to invoice certain customers in other currencies.
To the extent we receive revenues in currencies other than U.S. dollars, our
results of operations may be impacted by currency fluctuations. See "Risk
Factors--Foreign Exchange; Exchange Controls."

 Revenues

   Revenues from international long-distance services are derived from the
number of minutes of use billed by us and are recorded as the services are
rendered, after deducting an estimate for the traffic for which revenue will
not be collected. Historically deductions have not been material. Revenues from
prepaid calling cards are recognized at the time of usage or upon expiration of
the card. Revenues from private line services are recognized as earned on a
monthly basis.

   Customers may enter into agreements to purchase capacity from us in the form
of the granting of indefeasible rights of use, or IRUs, portable IRUs or
capacity leases. Revenue from the sale of capacity by us is recognized at the
date a customer first has access to the capacity, provided certain conditions
are met. IRU and portable IRU sales grant to the purchaser an indefeasible
right to use the unit of capacity sold for the time, usually the remaining life
of the system, to which the IRU applies. Once the IRU is granted to the
purchaser, the purchase price is non-refundable and the purchaser is required
to pay operations, administration and maintenance fees for as long as
connectivity is maintained. The proceeds from the long-term lease of capacity
are deferred and amortized over the term of the contract.

                                       34
<PAGE>

 Cost of Services

   TBI's cost of services is comprised primarily of local access charges and
international termination costs. Local access charges are paid to the Bermuda
Telephone Company for each minute of traffic that we originate or terminate in
Bermuda. As of January 1, 1999, the Minister of Telecommunications and
Technology's December 1998 directive reduced TBI's local access charge to $0.15
per minute for both originating and terminating traffic. The directive mandated
a second reduction on July 1, 1999 to $0.10 per minute, with a subsequent rate
determination to be made in December 1999.

   International terminations are completed through our correspondent carriers
and are charged to us on the basis of prevailing international settlement
rates. We receive return traffic on the major routes that effectively offset
our payments for Bermuda-originated traffic. Our primary correspondent carriers
are MCI WorldCom and British Telecom. The current settlement rates with
carriers in the United States and the United Kingdom, which comprise the
largest markets for Bermuda-originated traffic, are $0.35 per minute and the
equivalent of $0.48 per minute, respectively. The rates for international
terminations have declined recently and we expect they will continue to decline
as international conventions are modified and competition among international
carriers intensifies.

   For our wholesale carriers' carrier business, costs to build our systems are
capitalized. The cost of capacity sales are calculated on a pro rata basis of
total capacity sold in relation to the estimated total capacity.

 Operating Expenses

   Our operating expenses include network expenses and general and
administrative costs incurred to sustain and expand our Bermuda operations, as
well as to plan and finance the intended construction of the Atlantica-1
Network. As our systems develop, additional resources will be required to
provide for operations and for sales of capacity. Prior to the RFS date for the
connection from Tuckerton, New Jersey to Fortaleza, Brazil via Bermuda, we will
enter into an agreement with a third party that will provide operation,
administration and maintenance services on our systems. Following this RFS
date, we expect to recover a substantial portion of our operating,
administration and maintenance costs from periodic payments by customers. The
amounts of these payments will be based on the pro rata capacity purchased by
the customer in relation to the total capacity of the system. Each customer's
pro rata share will be capped and therefore, our share of operation,
administration and maintenance costs will be higher at the outset and will
decline over time as capacity is sold.

Results of Operations

 Six Months Ended June 30, 1999 Compared With Six Months Ended June 30, 1998

 Revenues

   Revenues increased to $13.1 million for the six months ended June 30, 1999
compared to $11.5 million for the six months ended June 30, 1998, an increase
of 13.9%. This increase was due primarily to an increase in commercial and
residential traffic carried over the BUS-1 system. Outbound revenues increased
to $9.9 million for the first half of 1999 compared to $8.4 million for the
first half of 1998, an increase of 17.9%, and inbound revenues increased to
$2.4 million for the first half of 1999 compared to $1.3 million for the first
half of 1998, an increase of 84.6%. The average rate per outbound minute
realized was $0.90 for the first half of 1999 compared to $.94 for the first
half of 1998. This reduction of $.04 per minute was due to a rate reduction for
commercial and residential customers introduced on April 1, 1999. Revenue from
TBI's debit card product increased to $474,000 for the first half of 1999
compared to $82,000 for the first half of 1998 when it was introduced. These
increases were offset by the lack of any IRU sales for the first half of 1999
compared to $1.5 million for the first quarter of 1998.

                                       35
<PAGE>

 Carrier Charges and Other Cost of Sales

   Carrier charges and other cost of sales decreased to $6.1 million for the
first half of 1999 compared to $7.4 million for the first half of 1998, a
decrease of 17.6%. The first half of 1999 is the first period that reflects the
reduced local access charges payable to the Bermuda Telephone Company for
Bermuda originating and terminating traffic.

   Local access charges for the first half of 1999 for Bermuda originating and
terminating traffic decreased to $2.6 million compared to $3.0 million for the
first half of 1998, a decrease of 13.3%. The decrease reflects the reduced
Bermuda Telephone Company charges but was offset largely by an increase in the
volume of traffic in the first half of 1999 as compared to 1998.

   Foreign settlements for the first half of 1999 decreased to $3.4 million
compared to $3.8 million for the first half of 1998, a decrease of 10.5%.
During the first halves of 1999 and 1998, the settlement rate with U.S.
carriers was $0.35 per minute and with U.K. carriers was the equivalent of
$0.52 per minute.

   The cost of the sale of cable capacity in the first half of 1998 totalled
$547,000. There were no capacity sales in the first half of 1999.

 General and Administrative Expenses

   General and administrative expenses increased from the first half of 1999
compared to the first half of 1998. These expenses for the first half of 1999
were $4.7 million compared to $4.5 million for the first half of 1998. This
increase reflects expenses in the first half of 1999 related to the start-up
and financing of the Atlantica-1 Network which were mitigated by a reduction in
the general and administrative expenses of TBI from the first half of 1998.

 Amortization Expense

   Amortization expense for the first half of 1999 increased to $1.4 million
from $1.3 million for the first half of 1998, an increase of 7.7%. This
increase resulted largely from the addition of network and telecommunications
equipment.

 Interest on Long-Term Debt

   Interest on long-term debt decreased to $1.58 million in the first half of
1999 from $1.59 million in the first half of 1998, a decrease of 0.6%. This
decrease resulted from lower than average borrowings in 1999 over 1998.

 Year Ended December 31, 1998 Compared With Year Ended December 31, 1997

   We began commercial operations in May 1997, initially providing service via
satellite pending the completion of the BUS-1 system in November 1997.
Accordingly, our results of operations for 1997 reflect only seven full months
of operation, as compared to the twelve months of operation in the 1998
results.

 Revenues

   Revenues increased to $26.7 million in 1998 compared to $5.0 million in
1997, an increase of 434.0%. This increase resulted primarily from an increase
in our market share in Bermuda and the sale of undersea fiber optic cable
capacity in 1998. Outbound revenues for 1998 increased to $18.4 million
compared to $4.5 million for 1997, an increase of 308.9%. Inbound revenues
increased to $5.7 million in 1998 compared to $0.4 million in 1997, an increase
of 1,325.0%. The average rate per outbound minute realized was $0.94 in 1998
and 1997.

   Bulk capacity sales on the BUS-1 system to two major international carriers,
in the form of IRUs, were completed in 1998 for aggregate proceeds of $1.5
million. In addition, a Bermuda-based ISP leased bulk

                                       36
<PAGE>

capacity on the BUS-1 system, for a 10- to 25-year term, at a total price of
$8.0 million. The proceeds from the IRU sales were recognized in 1998 while the
proceeds from the leased capacity are deferred and amortized over 25 years.

 Carrier Charges and Other Cost of Sales

   Carrier charges and other cost of sales increased to $15.7 million in 1998
compared to $3.6 million in the previous year, an increase of 336.1%. This
increase resulted primarily from higher traffic in 1998, partially offset by
the impact of reduced settlement rates with foreign carriers.

   Local access charges for Bermuda originating and terminating traffic
increased to $7.3 million in 1998 compared to $1.5 million in 1997, an increase
of 386.7%. Local access charges for 1998 were levied on the basis of a
government approved tariff of $0.27 per minute for originating traffic and
$0.24 per minute for terminating traffic. These rates remained unchanged from
the previous year. The increase in the charges resulted from an increase in
traffic on our system.

   Foreign settlements for 1998 totaled $7.6 million compared to $2.1 million
for the previous year, an increase of 261.9%. During 1998, the settlement rate
with U.S. carriers was reduced from $0.51 to $0.35 per minute and the U.K. rate
was reduced from the equivalent of $0.62 to $0.48 per minute. The increase in
the amount of charges resulted from an increase in traffic on our system.

   The cost of the sale of cable capacity in 1998 totaled $547,000. There were
no capacity sales in 1997.

 General and Administrative Expenses

   General and administrative expenses in 1998 increased to $9.3 million
compared to $5.1 million for the previous year, an increase of 82.3%. This
increase resulted primarily from the cost of additional staff and marketing
expenditures required to acquire market share in Bermuda. Significant
additional staffing should not be required to expand and maintain the Bermuda
business. However, as the Atlantica-1 Network develops, staffing levels for
selling and network operations will be increased substantially.

 Amortization Expense

   Amortization expense increased to $2.7 million in 1998 compared to $0.8
million in the previous year, an increase of 237.5%. This increase is primarily
attributable to the addition of the BUS-1 system in November 1997. Amortization
expense related to the BUS-1 system was $1.8 million in 1998 compared to $0.2
million in the previous year, an increase of 800.0%.

 Interest on Long-Term Debt

   Interest on long-term debt increased to $3.5 million in 1998 compared to
$0.8 million in 1997, an increase of 337.5%. This increase resulted primarily
from higher average borrowings in 1998.

 Year Ended December 31, 1997 Compared with Ten Months Ended December 31, 1996

   We did not provide telecommunications services prior to 1997. Therefore, we
did not have any revenues or carrier charges and other cost of sales in the ten
months ended December 31, 1996. In addition, the periods are not directly
comparable because the period ended December 31, 1997 was for 12 months while
the period ended December 31, 1996 was for only 10 months.

 Revenues

   Revenues increased to $5.0 million in 1997. We had no revenues in 1996. On a
monthly basis outbound revenue increased from $0.3 million in June 1997 to $1.0
million in December 1997. Inbound traffic from MCI

                                       37
<PAGE>

Worldcom and British Telecom began in August 1997 and contributed to
approximately 7% of the revenue for the 1997 year. At December 1997, inbound
traffic represented 10% of revenue for the month.

 Carrier Charges and Other Cost of Sales

   Carrier charges and other cost of sales increased to $3.6 million in 1997.
We had no carrier charges and other costs of sales in 1996. The cost of
services was relatively high in 1997 because the BUS-1 system did not become
operational until November 1997 and traffic was carried via satellite until
that time. Also, settlement rates with foreign carriers were relatively high in
1997 until volume-related price reductions were established with these
carriers.

 General and Administrative Expenses

   General and administrative expenses increased to $5.1 million in 1997
compared to $3.4 million in 1996, an increase of 50.0%. This increase resulted
largely from the development of network, sales and customer service
infrastructure to support our service offerings and operations.

 Amortization Expense

   Amortization expense increased to $847,000 in 1997 compared to $1,000 in
1996 as the BUS-1 system became operational.

 Interest on Long-Term Debt

   Interest on long-term debt increased to $750,000 in 1997 as our recently
retired subordinated loans and TBI's recently retired credit facility were
obtained to finance the BUS-1 system, and funds were drawn from these
facilities. We had no interest on long-term debt in 1996.

Liquidity and Capital Resources

 Future Capital Expenditures and Capital Resources

   The development of the Atlantica-1 Network will require us to make
significant capital expenditures in connection with building the undersea cable
system and the related landing stations, and securing terrestrial capacity to
connect the landing stations with major cities. We estimate the total cost to
build the Atlantica-1 Network, including the secondary strand of the Rio
extension, the Caracas extension, landing stations and capital contingencies,
will be $825 million. This estimate does not include potential capital costs,
if any, associated with securing terrestrial capacity, including any
terrestrial extension to Buenos Aires, Argentina. We are examining potential
terrestrial alternatives that would eliminate the need for building the
secondary strand of the Rio extension and the Caracas extension and reduce
costs accordingly. See "Business--Cable System Overview." We expect the primary
ring of the Atlantica-1 Network to be RFS in December 2000.

   We have commitments under our supply contract with Alcatel to make payment
installments in varying amounts as construction milestones are achieved on the
Atlantica-1 Network. The total of these payment installments is as follows:

  . six months ended December 31, 1999$130,172,000

  . six months ended June 30, 2000 242,345,000

  . six months ended December 31, 2000 248,344,000

   We expect to use the net proceeds we received from the private offering of
the old notes, the private equity financing (net of the proceeds we used to
repurchase outstanding shares of the Company from existing shareholders) and
the exercise of warrants by our former subordinated lenders, together with
available funds under Holdings' bank credit facility, to finance:

  . the construction of the Atlantica-1 Network,

  . transaction costs related to our financings,

  . the repayment of our subordinated loans and TBI's credit facility,

  . pre-RFS working capital requirements, and

  . costs, if any, associated with our initial requirements for terrestrial
    capacity.

                                       38
<PAGE>

   We have already repaid our subordinated loans and TBI's credit facility and
paid transaction costs from these funds. See "Use of Proceeds."

   We may in the future build an additional undersea cable system, the
Atlantica-2 Network, to connect Bermuda to the United Kingdom and Southern
Europe if there is sufficient demand and available capital. We are also
considering other potential undersea fiber optic cable system routes that we
believe are currently underserved. We have not decided whether we will build
the Atlantica-2 Network and we do not believe that building the Atlantica-2
Network is necessary for the success of the Atlantica-1 Network. If we build
the Atlantica-2 Network or another undersea fiber optic cable system, we will
require additional financing.

   Our expectations of required capital expenditures are based upon our current
estimates. Our actual capital expenditures could vary from our estimates and
these variations could be material. See "Risk Factors--Substantial Future
Capital Requirements."

 Historical Capital Expenditures and Capital Resources

   We have incurred significant operating losses and capital expenditures
related to the development of TBI. We have financed these expenditures through
a combination of borrowings under TBI's recently retired credit facility and
the recently retired subordinated loans, and equity contributions.

   Total cash provided by (used in) operating activities during the six months
ended June 30, 1999 and fiscal years 1998 and 1997 was $7.2 million, $(3.5)
million and $5.4 million, respectively. The cash provided by operations in 1997
and the use of cash by operations in 1998 was due primarily to a large accrual
for the cost to complete the BUS-1 system in 1997 which was paid in early 1998.
The cash provided by operations for the six months ended June 30, 1999 was
largely the result of a $6.0 million accrual for initial costs incurred on the
Atlantica-1 Network.

   Total cash provided by (used in) investing activities during the six months
ended June 30, 1999 and fiscal years 1998 and 1997 were $(5.5) million, $(1.8)
million, and $(43.1) million, respectively. Cash used in investing activities
in 1997 was primarily associated with the cost of constructing the BUS-1
system. The cash used in investing activities for the six months ended June 30,
1999 was primarily associated with initial construction costs incurred on the
Atlantica-1 Network.

   TBI's projected capital expenditures for fiscal 1999 are approximately $1.1
million, of which $0.4 million has already been spent as of June 30, 1999.
Although we do not expect further capital expenditures for TBI to be
significant, the development of the Atlantica-1 Network will require
significant additional financing. See "Use of Proceeds." Currently, our primary
sources of liquidity are cash flows from operations, net funds that we received
from our private offering of old notes and private equity financing, and
borrowing availability under Holdings' bank credit facility.

   Total cash provided by (used in) financing activities during the six months
ended June 30, 1999 and fiscal years 1998 and 1997 was $(3.7) million, $6.9
million and $29.2 million, respectively. To fund the construction of the BUS-1
system, during 1997 we borrowed $16.7 million under TBI's retired credit
facility and $13.0 million under our retired subordinated loans. We borrowed an
additional $6.9 million under TBI's credit facility in 1998 to finance working
capital requirements and capital expenditures.

   We used a portion of the net proceeds that we received from the private
offering of old notes and the private equity financing to repay TBI's credit
facility. The principal amount of the subordinated loans were also retired, and
accrued interest owed to one of the subordinated lenders was repaid, in
connection with the exercise of warrants by these subordinated lenders. We paid
accrued interest owed to the other subordinated lender out of the net proceeds
of the private offering of old notes and the private equity financing. See "Use
of Proceeds."

Seasonality

   Our Bermuda operations experience seasonal fluctuations that are a function
of the volume of tourist traffic. Traffic declines during the winter months
when tourist traffic is low.

Year 2000 Problem

   We are currently working to resolve the potential impact of the year 2000
problem on the processing of date-sensitive information by our computer systems
and programs. The year 2000 problem is the result of computer programs being
written using two digits, rather than four, to indicate the year. Any of our
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000, which could result in miscalculations
or system failures and lead to disruptions in operations.

   In 1998, we formed a year 2000 task force to conduct a comprehensive review
of our computer programs and systems to ensure that these programs and systems
will function properly and be year 2000 compliant. This review has included
both hardware and software systems and embedded technology systems. Remediation
has been or will be accomplished through a combination of hardware and software
upgrades, program changes and replacement of non-compliant systems. We do not
expect our remediation costs to be material.

   We have completed approximately 98% of our year 2000 compliance process and
expect to have completed the entire process by the end of October 1999. We
completed our internal compliance process in April 1999 and completed the
inter-carrier compliance process with the Bermuda Telephone Company in July
1999. We have spoken with third-party vendors that supply our computer programs
and systems as well as various carrier parties that provide us services that
are reliant upon our computer programs or systems. As of April 1999, we
successfully completed all system updates and system tests on our switching
equipment with our equipment and software vendor Northern Telecom. We have also
been advised by our principal vendors and manufacturers of our other electronic
equipment, such as personal computers, that this equipment is year 2000
compliant. We have also been advised by Data True, the subcontractor that
provides billing services for TBI's commercial accounts, that many of its
software products are year 2000 compliant and that it expects to be fully
compliant by the end of October 1999.

   The Bermuda Telephone Company, the local exchange provider upon which we
rely to originate and terminate our international long-distance traffic in
Bermuda and to process billing for our residential customers, has advised us
that it has successfully completed system tests on its switching equipment with
its equipment and software vendor Northern Telecom, and that it is year 2000
compliant. We completed end-to-end testing with the Bermuda Telephone Company's
system in July 1999. Northern Telecom conducted the testing.

   We believe that the costs of addressing potential problems will not have a
material adverse effect on our business, financial position or results of
operations unless our vendors and certain carrier parties fail to resolve year
2000 compliance issues in a timely manner.

   We believe that the action plans that we have developed and the
implementation time frames that we have established adequately allow for
unexpected issues that might arise. However, if the Bermuda Telephone Company
is unable to provide services because of the year 2000 problem, then our
customers will not be able to complete their international long-distance calls.
To the extent that we experience any other year 2000 problems, we believe that
these problems would be more likely to result in errors in our billing and
record-keeping functions, rather than in the ability of the Atlantica-1
Network, which has an RFS date in December 2000 for the primary ring, or the
BUS-1 system to provide telecommunications capacity to customers. If these
billing and record-keeping errors were to occur, we believe that we have
adequate contingency plans to determine the correct billing and other
information.

   Nevertheless, we cannot assure you that we will not experience any year 2000
problems, and it is difficult to predict the extent or magnitude of a year 2000
problem as it may affect us. To the extent that we experience material year
2000 problems and do not have a contingency plan in effect to remedy the
problem, our business,

                                       40
<PAGE>

financial condition and results of operations could be materially adversely
affected. While we believe the occurrence of this scenario is unlikely, a
possible worst case scenario might include (1) our inability to provide some or
all of the services designed to be provided by the BUS-1 system and the
Atlantica-1 Network, (2) delays, inaccuracies or other difficulties with
respect to billing customers or the loss of customers records, and (3) our key
vendors not being able to provide goods and services on a timely basis. The
financial impact of any or all of these worst case scenarios has not been and
cannot be estimated by management with any degree of meaningful precision due
to the numerous uncertainties and variables associated with these scenarios.

Quantitative and Qualitative Disclosure About Market Risk

   We are exposed to various market risks relating to changes in foreign
currency exchange rates and interest rates. Market risk is the potential loss
arising from adverse changes in market prices and rates, such as foreign
currency exchange and interest rates. We do not enter into derivatives or other
financial instruments for trading or speculative purposes.

 Foreign Currency Exposure

   We are exposed to fluctuations in foreign currencies relative to the U.S.
dollar. Because the Bermuda dollar is pegged to the U.S. dollar, there is no
foreign currency exposure for transactions conducted in this currency. Our
foreign currency exposures as at December 31, 1998 are as follows:

   Note Receivable: We have a note receivable of (Pounds)250,000 which is non-
interest bearing and due November 20, 2000.

   Accounts Payable: We have an account payable of 448,343 SDR's, a notional
currency tied to a basket of European currencies, to one of our carriers. This
payable is current and non-interest bearing.

   Settlements on International Traffic: Settlements on international traffic
are largely made in U.S. dollars. For the year ended December 31, 1998,
approximately 8% of the Company's cost of sales and 3% of the Company's revenue
was denominated in a currency other than the U.S. dollar.

 Interest Rate Exposure

   We owed approximately $37.0 million of variable-rate long term debt as at
December 31, 1998. The interest rate on this debt fluctuates with the London
Interbank Offered Rate. We do not hold any derivatives related to interest rate
exposure for any of our debt facilities. However, Holdings' bank credit
facility will require us to enter into interest rate hedging transactions in
the near future. See Note 9 to our consolidated financial statements for more
information on our debt.

                                    BUSINESS

Business Overview

   We will provide our customers with customized city-to-city international
telecommunications network solutions on a wholesale "carriers' carrier" basis
using technologically advanced undersea fiber optic cable systems and
terrestrial extensions. We are currently developing the Atlantica-1 Network, a
high capacity, self-healing, undersea fiber optic cable system that, together
with terrestrial extensions, will offer seamless connectivity between certain
major cities in the United States, Brazil, Venezuela, Bermuda and Argentina. In
addition, we intend to expand the reach of the Atlantica-1 Network by offering
connectivity to other countries in South America and Europe through a
combination of commercial arrangements, capacity purchases and further
development of undersea or terrestrial fiber optic cable systems.

   We are developing the Atlantica-1 Network to satisfy increasing bandwidth
requirements for the transmission of voice, data and video, particularly over
the Internet, between North America and South America. We intend to offer
customized and flexible provisioning of capacity at competitive prices to
international telecommunications service providers, including emerging and
established carriers, ISPs and value-added resellers. We expect that initially
the majority of our customers will be North American and European
telecommunications service providers or their South American affiliates.

   The Atlantica-1 Network will be a 22,500 km four fiber pair undersea fiber
optic cable system. We have selected Alcatel to design, construct and install
the Atlantica-1 Network pursuant to a turnkey contract. The total activated
capacity of the Atlantica-1 Network initially will be 40 Gbps, but will be
upgradeable to 1,280 Gbps using dense wavelength division multiplexing, or
DWDM, technology. The primary ring of the Atlantica-1 Network will connect the
United States, Bermuda, Brazil and Venezuela. The connection from Tuckerton,
New Jersey to Fortaleza, Brazil via Bermuda is scheduled to be RFS by September
2000, with the full primary ring scheduled to be RFS by December 2000. We
believe that the deployment of the Atlantica-1 Network will position us as one
of the first private undersea fiber optic cable systems that, together with
terrestrial extensions, will offer city-to-city connectivity between the United
States, Brazil, Venezuela, Bermuda and Argentina.

   In order to provide city-to-city connectivity, we will secure terrestrial
extensions, through either cash purchases or capacity swaps, from each
Atlantica-1 Network landing point to certain major cities in North America and
South America. We are currently in discussions with providers of backhaul
capacity to provide connectivity between the following cities, at a minimum:

  . New York City, Boston, Washington, Atlanta and Miami in the United
    States,

  . Sao Paulo, Rio de Janeiro, Belo Horizonte, Brasilia and Fortaleza in
    Brazil,

  . Buenos Aires in Argentina,

  . Caracas in Venezuela, and

  . Hamilton in Bermuda.

   The Atlantica-1 Network will also provide interconnection with Western
Europe through a number of transatlantic cable systems, including a planned
system in which we have a minor ownership interest --TAT-14.

   We currently provide international telecommunications services to both
residential and commercial customers in Bermuda through our subsidiary TBI.
TBI, which commenced service in May 1997, is one of only two carriers licensed
to provide international telecommunications services to customers in Bermuda.
In approximately two years, we have achieved a market share in excess of one-
third of the Bermuda outbound long-distance market. In November 1997, we
successfully completed the deployment of the BUS-1 system, which connects
Bermuda and the United States. The BUS-1 system, which will be incorporated
into the Atlantica-1 Network, established us as a full-service facilities-based
provider of international long-distance

                                       42
<PAGE>

service for traffic originating and terminating in Bermuda. We do not intend to
offer telecommunications services to retail customers outside of Bermuda.

   TBI's products include:

  . switched international direct distance dialing,

  . calling cards,

  . debit/prepaid calling cards, and

  . international private line services.

Market Opportunity

   We are developing the Atlantica-1 Network to capitalize on a combination of
factors that are increasing the demand for telecommunications capacity to carry
voice, data and video between North America and South America. We hired IBM
Global Services, an independent telecommunications industry consultant, to
perform a demand assessment for the Atlantica-1 Network. IBM Global Services
analyzed trends in telecommunications, social, economic and technological
developments and conducted interviews with several carriers to assess the
demand for telecommunications capacity between North America and South America.
Based on this analysis, IBM Global Services believes that demand for
telecommunications capacity between North America and South America will grow
at a compound annual rate of approximately 60% to 70% from 1997 to 2004.

 Increasing Global Demand for International Telecommunications Capacity

   The dramatic increase in global demand for international telecommunications
capacity is being driven primarily by rapid increases in the use of high
bandwidth applications, and by a global trend towards privatization and
deregulation of telecommunications industries. Prior to 1995, growth in demand
for international telecommunications capacity was driven primarily by voice
traffic, which has grown by approximately 15% per year during the past decade.

   However, we expect Internet and data traffic growth to significantly outpace
voice traffic growth. Internet traffic alone has grown at a rate of
approximately 100% per annum during the last three years. The growth in data
traffic globally is being generated by rapid increases in the use of high
bandwidth applications, such as Internet, e-commerce, video-on-demand,
corporate Intranets and Extranets, video-conferencing, electronic data
interchange, or EDI, transactions between businesses, CAD/CAM manufacturing
techniques, distance learning applications and medical applications. We expect
that growth in Internet and data traffic will be the largest driver of
increasing demand for international telecommunications capacity.

 Deregulation and Privatization of South American Telecommunications Industries

   Many South American countries have recently completed, or are in the process
of, deregulating and privatizing their telecommunications industries. Based on
the experience in other telecommunications markets, we expect that deregulation
and privatization in South America will:

  . increase the development of telecommunications infrastructure and
    teledensity,

  . accelerate growth in domestic and international traffic, and

  . lead to the creation of new international telecommunications service
    providers.

   Countries with low teledensities generally experience increased teledensity
after privatization of their telecommunications markets because of the creation
of more efficient, higher capacity terrestrial telecommunications networks that
make access to telecommunications services less expensive and more widely
available. Privatization also drives the emergence of new domestic and
international telecommunications

                                       43
<PAGE>

service providers that typically offer enhanced services and lower pricing than
the incumbents. Many of these telecommunications service providers are seeking
to establish global high speed network facilities through the lease or purchase
of undersea fiber optic capacity from independent sources. We also expect
privatization to accelerate international traffic. The international accounting
rate/settlement system, which historically contributed to artificially high
international calling rates, is eroding. As a result, tariffs are declining and
the demand for international telecommunications services, which has
demonstrated significant price elasticity in deregulating countries, is
increasing and stimulating revenue growth. The presence of competitors in the
market has consistently produced accelerated growth in international traffic.

   Brazil: In Brazil, the recent privatization and deregulation of the
telecommunications industry generated in excess of $19 billion in new
investment in 1998. The majority of this investment came from major U.S. and
European-based carriers, such as MCI WorldCom, Sprint International, Portugal
Telecom, Telefonica de Espana and Telecom Italia. The Brazilian government
expects investment in excess of $50 billion in new telecommunications
infrastructure over the next seven years, in part to meet a government mandate
to expand teledensity from approximately 11.5 phone lines per 100 people to
23.0 phone lines per 100 people by 2003. These teledensity levels are
relatively low compared to the approximately 60 phone lines per 100 people in
the United States and Canada. We expect that the anticipated investment in
telecommunications infrastructure, phased deregulation scheduled for completion
in 2002 and anticipated increase in teledensity will result in increased
international telecommunications traffic to and from Brazil.

   Venezuela: Approximately $4.5 billion has been invested in Venezuela in the
telecommunications market since the privatization of CANTV, the incumbent
monopoly carrier, and the award of a wireless license to TelCel in 1991, and we
expect that an additional $3 to $4 billion will be invested over the next five
years. Venezuela has committed to opening its markets to competition for
facilities-based voice telephone services in all sectors of the market (local,
long-distance and international) by November 2000. We expect additional new
entrants in Venezuela over the next few years as deregulation and privatization
create market opportunities. We expect the Atlantica-1 Network to be a positive
factor influencing new entrants seeking reasonably priced, high quality
international telecommunications capacity.

   Argentina: Argentina's privatization and deregulation schedule contemplates
licensing two long-distance service providers before November 1999, in addition
to the incumbents Telefonica de Argentina and Telecom Argentina, which
currently hold exclusive operating licenses for local and long-distance
telephony. Telefonica de Argentina operates in the southern half of the country
and Telecom Argentina operates in the northern half. We anticipate that the
Argentinean government will impose infrastructure expansion requirements
similar to Brazil's regulations in connection with market deregulation. We
expect that Argentina will experience similar growth as seen in other countries
post-deregulation and believe that the Atlantica-1 Network will be in a
position to serve as a feeder system for traffic between Argentina and much of
the rest of South America and North America.

 Increasing Demand for Telecommunications Capacity Between North America and
 South America

   We expect that the increase in demand for bandwidth-intensive Internet and
data services in South America will be the primary stimulant of demand for
telecommunications capacity between North America and South America. According
to industry sources, Internet users in South America are expected to increase
from approximately 8.5 million in 1998 to approximately 34 million by the end
of 2000, representing one of the fastest growth rates in the world. As the
number of Internet users in South America increases, the concentration of
Internet hubs and corporate Intranets in the United States is expected to drive
increased growth in telecommunications traffic between North America and South
America.

   In addition, we expect incoming and outgoing voice traffic between North
America and South America, which has grown at a compound annual rate of 21% per
annum over the past five years, will continue to contribute to the increase in
demand for bandwidth. The table below summarizes the volume and compound

                                       44

 Limited Existing Telecommunications Capacity Between North America and South
 America

   The existing undersea fiber optic cable systems connecting the major cities
in North America and South America have limited capacity. While there has been
substantial development of east-west fiber optic network capacity in recent
years (both trans-Atlantic and trans-Pacific), there has been limited
development providing connectivity between North America and South America.
This limited availability presents a significant opportunity for a new,
independent north-south undersea fiber optic cable system such as the
Atlantica-1 Network.

   Due to the scarcity of undersea fiber optic cable systems, a majority of
telecommunications traffic between North America and South America has
historically been transmitted via satellite. Satellite transmission is
generally considered to have some advantages over cable transmission with
respect to point-to-multipoint broadcast and "thin route" transmission, as
opposed to the more common point-to-point, high volume transmission for which
undersea cable systems usage is considered to be preferable. Satellites,
however, provide inferior quality versus fiber optic cable systems in terms of
transmission delay, voice quality and transmission throughput for data. In
addition, satellite transmission is substantially more expensive than fiber
optic cable systems on a per unit basis for heavy traffic routes. We believe
that the vast majority of the growth in demand for cable systems will be met
through undersea fiber optic cable systems, with satellites providing video
broadcast signals, route diversity, and restoration for non-ring and low
capacity fiber optic networks.

   The existing undersea cable systems connecting North America and South
America have a number of shortcomings that limit their ability to meet the
projected rapid increase in demand for bandwidth. Much of the existing capacity
does not connect to Rio de Janeiro, Sao Paulo or Buenos Aires, and thus does
not directly provide access to major telecommunications traffic points of
origin and termination. The existing undersea cable systems utilize older
technology and therefore generally offer limited capacity and have limited
ability to upgrade. In addition, no undersea cable systems in the region
currently offer self-healing restoration capabilities. Therefore, restoration
may only be partial or non-existent. We believe that restoration is a
fundamental requirement for telecommunications service providers offering
state-of-the-art service levels, particularly for mission critical data
applications.

   Finally, each of the existing undersea cable systems was developed on a
consortium basis, and all available capacity is currently committed to the
consortium members. Access to this capacity is available to third parties only
to the extent a consortium member, increasingly a competitor to potential
purchasers, is willing to resell its unused capacity, if any.

   The planned development of two other new undersea cable systems in the
region with capacity, technology and scheduled completion dates similar to ours
has recently been announced. We believe that the limited existing availability
and the expected growth in demand for capacity represents a significant
opportunity for the

Atlantica-1 Network and these other systems. See "Risk Factors--Competition"
and "Business--Competition."

Business Strategy

   Our business strategy is to provide customized and seamless city-to-city
international telecommunications network solutions to wholesale purchasers,
including emerging and established telecommunications carriers, ISPs and value-
added resellers. Key elements of our strategy include:

 Become a Preferred Independent Carriers' Carrier

   We intend to be a carriers' carrier. We will provide to our target customers
an independent source of international telecommunications capacity with city-
to-city connectivity offered under an efficient one-stop-shop approach. We
believe that our independent status will be a significant marketing advantage
because we will not be perceived as competing with our customers. We believe
that our potential customers will be less inclined to purchase capacity from
their competitors if they have a readily available, technologically advanced
alternative through an independent provider. By purchasing from an independent
provider, customers can avoid subsidizing their competitors and providing them
access to sensitive traffic data.

 Be Early to Market

   We believe that the deployment of the Atlantica-1 Network will position us,
together with the two other recently announced systems that are expected to
have completion dates similar to ours, among the first private undersea fiber
optic cable systems to offer connectivity between North America and South
America. Further, we believe that we will be the first independent undersea
cable system to provide connectivity between North America and South America.

   We expect this early to market presence to represent a competitive advantage
for the early participants in obtaining capacity commitments from major
carriers and ISPs because having an operational cable system will enable the
early participants to establish a foothold with major telecommunications
carriers and ISPs by meeting their rapidly increasing capacity needs. We also
believe that construction of undersea cable systems that would compete with
these early participants will be limited in the near future due to various
barriers to entry, including:

  . the substantial capital required to develop undersea cable systems,

  . the extensive lead time required for the development of cable systems,

  . the strong global demand for the limited resources of major undersea
    cable supply and construction companies, including competing demand for
    production slots for newly announced systems, and

  . the limited number of qualified personnel with the necessary experience
    in the undersea cable industry.

   Further, the ability of the Atlantica-1 Network and the other recently
announced undersea cable systems to upgrade capacity in advance of expected
demand at a substantially lower unit cost than the cost of original
construction could tend to discourage further undersea cable system development
between North America and South America.

 Provide Customized and Flexible Network Solutions

   We intend to provide customized solutions to meet the international
telecommunications capacity needs of our customers. We will offer:

  . a broad range of bandwidth options, from smaller units of capacity (E-1s,
    DS-3s) to larger units of capacity (STM-1s, STM-16s, STM-64s),

                                       46
<PAGE>

  . flexible provisioning of capacity at competitive prices to enable our
    customers to optimize their capacity purchase decisions based on their
    unique requirements and competitive strategies. Our product packages will
    include IRUs, portable IRUs and short-term leases with options to buy
    IRUs, which will be offered under a variety of payment options,

  . customers the ability to acquire capacity on shorter notice than has been
    typically offered by traditional carrier consortium systems, allowing our
    customers to minimize long-term capital commitments and reliance on long-
    term demand projections, and

  . a variety of network provisioning and maintenance services, collocation
    facilities and technical support options, including offering our larger
    customers access to a network management system which will give them
    real-time control over their capacity, circuit reassignment and testing
    requirements.

 Develop a Technologically Advanced Network

   The Atlantica-1 Network will be a technologically advanced, upgradeable,
undersea fiber optic cable system configured in a self-healing ring. We believe
the restoration capability of the Atlantica-1 Network will be a significant
competitive advantage over existing systems in the region, which must acquire
restoration capability from other systems or satellites. Further, the existing
systems in the region were designed and built with a limited ability to upgrade
capacity, and therefore must be supplemented by the construction of additional
undersea cable systems to increase capacity significantly.

 Capitalize on Bermuda Advantage

   We believe that our Bermuda location will be advantageous to our customers
in developing e-commerce and least-cost routing business opportunities as a
result of a combination of factors:

  . favorable tax regime,

  . strategic geographic location,

  . favorable regulatory environment,

  . stable political environment, and

  . technologically advanced telecommunications infrastructure.

   We intend to promote the hosting of customers' servers, databases and
related equipment in our facility in Bermuda to enable our customers to perform
their e-commerce functions in this strategic location.

 Leverage Extensive Management Experience

   We have assembled a strong management team and will continue to hire highly
qualified individuals. Our management team was responsible for the successful
financing and deployment of the BUS-1 system, one of the first private
international undersea fiber optic cable systems, and for the successful launch
of our long-distance business in Bermuda. Our management team also has
substantial international telecommunications network development and operating
experience with major international carriers, including MCI WorldCom and
Teleglobe. The team is led by Jerry A. DeMartino, President and Chief Executive
Officer, who recently served as President of MCI International and Senior Vice
President of Global Strategy and Development for MCI WorldCom. Michael Kedar,
our Executive Chairman, who founded TBI in 1995, continues as an integral
member of management. Mr. Kedar is a well-known telecommunications entrepreneur
who also founded Call-Net Enterprises Inc. (Sprint Canada), one of Canada's
leading long-distance carriers, and Microcell Communications Inc., a PCS
provider in Canada.

Cable System Overview

 Atlantica-1 Network

   The Atlantica-1 Network will be a 22,500 km four fiber pair undersea fiber
optic cable system. The Atlantica-1 Network is being engineered and constructed
using the latest in fiber optic technology, self-healing ring structures,
erbium doped fiber amplifier repeaters, LEAF, DWDM, system and equipment
redundancies and a fully integrated network management system. The
incorporation of this advanced technology will allow us to offer fully
redundant, self-healing capacity to our customers at competitive prices
relative to existing and planned systems.

   The Atlantica-1 Network design contemplates system interconnection with
other existing and planned cable systems at various landing points in order to
provide customers with seamless and cost-effective connectivity to major cities
in Europe, the United States, Bermuda and South America.

   The initial capacity of the Atlantica-1 Network will be 40 Gbps of total
capacity or 20 Gbps of self-healing capacity. The system will be upgradeable to
1,280 Gbps of total capacity or 640 Gbps of self-healing capacity. We will
upgrade the system incrementally in advance of expected demand. It may require
up to 12 months for an upgrade to be implemented. The Atlantica-1 Network will
incorporate the BUS-1 system for the portion of the primary ring from
Tuckerton, New Jersey to St. David's, Bermuda. The BUS-1 system will have an
initial total capacity of 40 Gbps or an initial self-healing capacity of 20
Gbps when incorporated into the Atlantica-1 Network. Modeling of the BUS-1
system performed by Alcatel indicates that the BUS-1 system could be capable of
achieving total capacity of 80 Gbps. Alcatel completed tests on the BUS-1
system on August 6, 1999 to determine its ultimate total capacity, and a final
report is expected in October 1999. Preliminary indications are that 80 Gbps
per fiber pair is achievable. Once demand exceeds the BUS-1 system's ultimate
total capacity, we intend either to replace or supplement the system with a new
undersea cable at an anticipated cost of approximately $40 million.

   The self-healing system will provide two forms of switching protection
against faults: span switching and ring switching. Span switching provides
protection between adjacent landing stations if the fault involves only one of
the two fiber strands. Ring switching provides protection if there is a fault
involving all fibers between adjacent landing stations. Self-healing capacity
is designed to protect customers against the effect of potential equipment and
cable failures. The Atlantica-1 Network's internal restoration system is
expected to react to failures in less than 300 milliseconds, with no noticeable
degradation in service or dropped calls. Without the ring configuration, users
would need to buy restoration services on alternate systems to ensure the
continuity of their network transmission. Restoration obtained on alternate
systems is subject to a delay of several hours from the time the fault occurs
until the traffic is rerouted.

   As shown in the chart below, the principal components of the Atlantica-1
Network will be the primary ring, the Rio extension and the Caracas extension.

    estimated cost also excludes potential costs, if any, associated with
    securing terrestrial capacity, including any terrestrial extension to
    Buenos Aires, Argentina.
(2) Fixed price under our turnkey contract with Alcatel.
(3) We have an option in our contract with Alcatel to build the secondary
    strand of the Rio extension. We currently intend to exercise this option
    unless we can obtain capacity on a terrestrial system from a third party at
    a lower cost. If we do not exercise our option to build the secondary
    strand, the cost of building the Rio extension will be $119 million, plus
    the cost, if any, of obtaining capacity on a terrestrial network. We expect
    the target service date to be approximately 18 months from the date of
    exercising the option.
(4) We are currently negotiating with Alcatel to build the Caracas extension.
    We will build the Caracas extension unless we can obtain capacity on a
    terrestrial system at a lower cost and with the requisite operational
    control. We estimate that the cost to build the Caracas extension will be
    $10 million. We expect the targeted service date to be in or about December
    2000.

 Atlantica-2 Network

   Assuming sufficient demand and available capital, we may in the future
expand the system to provide connectivity between Bermuda and Southern Europe,
including Spain, Portugal and France, as well as the United Kingdom, with the
Atlantica-2 Network.

   We expect the Atlantica-2 Network to have a comparable unit price per
kilometer to the Atlantica-1 Network, but with newer technology, and to require
substantial capital to develop. We estimate that the Atlantica-2 Network could
have a potential RFS date as early as the fourth quarter of 2002. Our demand
and feasibility analyses regarding the Atlantica-2 Network are preliminary. We
will complete a more comprehensive analysis of the Atlantica-2 Network before
committing to its construction. We have no current commitment to build the
Atlantica-2 Network, and we do not believe that building the Atlantica-2
Network is necessary for the success of the Atlantica-1 Network. Further, there
are viable and possibly more suitable alternatives to serve Europe through
other cable systems.

 Terrestrial Extensions to Key Markets

   We will secure terrestrial extensions from each Atlantica-1 Network landing
point to certain major cities in North America and South America either through
strategic alliances with telecommunications service providers, with other
carriers or, if necessary, through our own construction. We are currently in
discussions with providers of backhaul capacity to provide connectivity between
the following cities, at a minimum: New York City, Boston, Washington, Atlanta
and Miami in the U.S.; Sao Paulo, Rio de Janeiro, Belo Horizonte, Brasilia and
Fortaleza in Brazil; Buenos Aires in Argentina; Caracas in Venezuela; and
Hamilton in Bermuda. We are also currently in discussions with major
telecommunications service providers who are contemplating the

                                       49
<PAGE>

construction of terrestrial fiber networks that, if linked with the Atlantica-1
Network, would provide additional direct connectivity to major cities in Chile,
Peru and Colombia.

   United States: The Atlantica-1 Network will have two landing stations in the
United States. One will be at or near the existing landing station for the BUS-
1 system in Tuckerton, New Jersey and the other, as presently contemplated,
will be in Boca Raton, Florida. The introduction of numerous new undersea cable
systems landing on the eastern seaboard in recent years, along with the rapid
construction of new competing major national terrestrial networks, has resulted
in the emergence of numerous suppliers of backhaul capacity capable of
connecting with the Atlantica-1 Network landing stations in the United States.
We have issued a request for proposal for the necessary terrestrial capacity to
15 potential suppliers and are in negotiations with some of these potential
suppliers. In some cases we may exchange capacity on the Atlantica-1 Network
for an equivalent value of backhaul capacity in the United States. We do not
foresee any difficulties in securing backhaul capacity in the United States.

   Brazil: We are currently in negotiations with potential suppliers of
backhaul capacity in Brazil. We plan to purchase backhaul capacity in Brazil to
provide our customers with connectivity between Rio de Janeiro and the cities
of Sao Paulo, Belo Horizonte and Brasilia. We have committed to build the
primary strand of the Rio extension to connect Fortaleza and Rio de Janeiro at
a cost of $119 million. We also have an option in our contract with Alcatel to
build the secondary strand of the Rio extension at a cost of $112 million.
Although we currently intend to exercise our option with Alcatel to build the
secondary strand, we are examining the relative costs of buying terrestrial
capacity from Fortaleza to Rio de Janeiro. If cost effective, we will not
exercise our option to build the secondary strand of the Rio extension and
instead will obtain backhaul capacity from Fortaleza to Rio de Janeiro.

   We are actively looking for a more cost effective terrestrial extension to
provide self-healing restoration for our Rio extension. We have identified
several companies planning to construct fiber optic networks from Fortaleza to
Rio de Janeiro. These companies include TeleMar (the incumbent licensee in the
northern region of Brazil), Embratel (the existing former monopoly carrier),
Bonari (a joint venture between Sprint/France Telecom/The National Grid) and
Canbra Telefonica S/A (Bell Canada International, Qualcomm, WLL International
and Vicunha). We believe that there will be significant development of
terrestrial capacity along this route over the next two years which will
provide us with several backhaul alternatives.

   We have also identified several potential suppliers of backhaul capacity
from Rio de Janeiro to Sao Paulo, Belo Horizonte and Brasilia. These network
providers include both Embratel as well as the mirror licensee, Bonari. In
addition, alternative network providers including MetroRed (owned by Fidelity
and Boston Ventures, among others), Netstream (a subsidiary of Promon, a
premier Brazilian engineering company) and Pegasus have developed or are
developing networks that could provide us with our required backhaul capacity.

   Venezuela: We have had discussions with both CANTV, the recently privatized
former monopoly, and TelCel, an affiliate of BellSouth International, with
regard to either the purchase of, or an exchange for, backhaul capacity from
Punta Gorda to Caracas. In the event we are unable to negotiate acceptable
arrangements with either domestic carrier, we may construct our own terrestrial
extensions. As another alternative, we are currently in negotiations with
Alcatel to build the Caracas extension. The cost of the Caracas extension,
which we estimate to be $10 million, is included in our projected capital cost
for the Atlantica-1 Network.

   Argentina: We have identified several potential suppliers of backhaul
capacity between Rio de Janeiro, Brazil and Buenos Aires, Argentina. In
addition to the incumbent monopoly carrier, Telefonica Larga Distancia de
Argentina, several alternative network providers, such as MetroRed, are
building fiber optic networks. These networks should provide connectivity not
only between Buenos Aires and Rio de Janeiro, but also to the other major
cities in Argentina. We believe that the expected deregulation of Argentina in
2000 will result in the emergence of additional new market entrants. In the
event that we are unable to secure backhaul capacity from

                                       50
<PAGE>

a third party, we are considering developing our own undersea cable system from
Rio de Janeiro to Buenos Aires.

   Bermuda: We plan to have our new landing station in Bermuda located close to
our St. David's network operations center that currently houses both the BUS-1
system electronics as well as our international gateway switch. We will secure
backhaul capacity from St. David's to Hamilton that is sufficient to meet our
customers' demands.

 Alcatel Contract and Cable Deployment Strategy

   We have selected Alcatel, a global leader in the construction and
installation of undersea fiber optic cables, as the supplier for the Atlantica-
1 Network. We have entered into an agreement with Alcatel which provides that
Alcatel, on a turnkey basis, will:

  . supply and install, at a fixed cost of approximately $502 million
    (excluding landing stations), the undersea portion of the primary ring by
    December 2000 (the connection from Tuckerton, New Jersey to Fortaleza,
    Brazil via Bermuda is scheduled to be RFS in September 2000) equipped
    with four fiber pairs and terminal equipment to support 20 Gbps of self-
    healing capacity, including the upgrade of the BUS-1 system to use 20
    Gbps of self-healing capacity,

  . supply and install, at a fixed cost of approximately $119 million
    (excluding landing stations), the primary strand of the Rio extension by
    February 2001 equipped with four fiber pairs and terminal equipment to
    support 20 Gbps of self-healing capacity,

  . at our option, which will expire on December 30, 2001, supply and
    install, at a fixed cost of approximately $112 million, the secondary
    strand of the Rio extension equipped with four fiber pairs and terminal
    equipment to support 20 Gbps of self-healing capacity. We estimate that
    it will take approximately 18 months from the date we exercise our option
    on the secondary strand of the Rio extension until the target service
    date,

  . seek and obtain on our behalf all permits and licenses (excluding landing
    licenses) required to implement the undersea portion of the Atlantica-1
    Network,

  . provide all training required for the operation and maintenance of the
    Atlantica-1 Network,

  . pay liquidated damages in the event of certain failures by Alcatel to
    deliver the Atlantica-1 Network by the scheduled RFS date for each of the
    primary ring, the connection from Tuckerton, New Jersey to Fortaleza,
    Brazil via Bermuda, and the primary strand of the Rio extension (up to
    10% of the initial contract value over the first 100 days of delay), and

  . at our option, which will expire on December 30, 2001, extend the
    Atlantica-1 Network through additional undersea cable systems.

   Certain factors may result in increased costs and later RFS dates than
discussed above. See "Risk Factors--Completion of the Atlantica-1 Network."
Pursuant to the contract, Alcatel has caused its ultimate parent company to
guarantee unconditionally, subject to certain limitations, the full and
punctual performance by Alcatel of its obligations under the contract. The
Alcatel contract also limits the damages that we could recover in the event of
a breach by Alcatel.

   We are currently negotiating with Alcatel to design and construct the
Caracas extension and the landing stations (including obtaining all required
permits and licenses, except for landing licenses) on either a fixed cost or
cost-plus basis, at an additional estimated cost of $55 million. On August 11,
1999, we signed an intent to proceed letter with Alcatel for the fixed price
turnkey supply of all six undersea cable stations and the associated overland
routes from the cable stations to the cable beach landing points at an
estimated cost of approximately $45 million. This intent to proceed letter
expires on October 30, 1999.

                                       51
<PAGE>

   We selected Alcatel as the system supplier on the basis of quality,
experience and price after reviewing competitive bids with several large
respected undersea cable suppliers. Alcatel, together with its ultimate parent
company, is a world leader in the development, manufacture, installation and
management of state-of-the-art undersea telecommunications cable networks,
transmission equipment, switching equipment and network management systems,
building upon the knowledge and expertise it has gained over the course of more
than 140 years of operating experience. Alcatel and its affiliates operate in
over 130 countries, and provides complete solutions and services to operators,
service providers, enterprises and consumers, ranging from backbone networks to
users' terminals.

 Operations, Administration and Maintenance Costs

   We will provide, or contract for the provision of, operations,
administration and maintenance services for the Atlantica-1 Network. For the
undersea fiber optic cable and terrestrial extensions, we expect to enter into
a contract with a third party at least six months prior to the RFS date for the
connection from Tuckerton, New Jersey to Fortaleza, Brazil via Bermuda to
provide operations, administration and maintenance services. There are a number
of potential providers of these services, including Alcatel and ACMA. For the
landing stations, we intend to train our personnel to provide operations,
administration and maintenance services at these facilities.

Sales and Marketing

 Products and Services

   We will offer a flexible range of product and pricing alternatives, at
competitive prices, designed to meet the needs of both emerging and established
carriers and telecommunications services providers, including ISPs and value-
added resellers.

   We intend to offer a broad range of bandwidth options, from smaller units of
capacity (E-1s, DS-3s) to larger units of capacity (STM-1s, STM-16s, STM-64s).
We believe that this broad product offering is currently unavailable to
customers seeking connectivity between North America and South America. We will
package this capacity in a variety of ways, from standard IRUs to leases.
Customers purchasing standard IRUs prior to a segment RFS date will pay a
portion of the purchase price upon execution of a contract to buy an IRU, with
the balance of the purchase price due to the Company upon the applicable RFS
date for that segment. Payment plans may be made available to qualifying
purchasers, although we plan to encourage full payment for IRUs on an up-front
basis through advantageous pricing. IRU ownership typically provides for a
fixed connection on the system for the entire design life, normally up to 25
years. We intend to satisfy shorter term requirements for capacity through
leases, with options to convert the leases into IRUs.

   In addition, we will offer our customers the ability to acquire capacity on
shorter notice than has been offered by the traditional carrier consortium
systems. This will enable customers to minimize long-term capital commitments
and reliance on long-term demand projections.

   For capacity purchases smaller than STM-1s, we will also offer customers, at
a premium, portable IRUs. Portable IRUs will allow a carrier to reassign its
purchased capacity to a different city or station pair on the Atlantica-1
Network. To support this product offering, we will be required to reserve
approximately 15% of the portable capacity as idle capacity on our network.
Carriers will be allowed to use this idle capacity for reassignment on a first-
come, first-served basis, and carriers reassigning their circuits will be
required to surrender their current routing to us for use by others. We will
also provide large capacity purchasers with access to the network management
system that will enable these purchasers to monitor their network's performance
on a real-time basis from end-to-end, control their operations and perform
circuit provisioning as needed.

   Purchasers of IRU capacity will pay their pro rata share of operations,
administration and maintenance charges based upon the level of expenses we
incur, or expect to incur, in the operation, administration and

                                       52
<PAGE>

maintenance of our systems. We intend to offer our IRU customers a choice
between paying a one time operations, administration and maintenance charge, or
paying, on a periodic basis, a fixed charge subject to CPI adjustments and
cost-savings flow-through. For customers purchasing capacity under a lease
agreement, operations, administration and maintenance costs will be included in
the lease payments.

   Our billing will be denominated in U.S. dollars wherever possible to
decrease our exposure to foreign currency risks. However, we might be required
to accept payment in local currencies for certain backhaul and other revenues
we receive from operations in certain foreign jurisdictions.

   We intend to promote various value-added offerings through which a customer
could utilize our Bermuda network and network operations center to generate
cost savings and optimize its income tax planning. These offerings include
providing (1) turnkey e-commerce and web hosting services, including systems
for order processing, financial transactions, and network-based fulfillment of
digital product, (2) broadband transmission capacity and hosting facilities for
(i) web sites utilizing the customer's own e-commerce systems or (ii) databases
providing service such as disaster recovery backup protection, and (3)
collocation of switches or other equipment to perform traditional circuit-
switched least-cost routing or IP-based routing, including emerging
international IP-based voice services.

   We believe that our infrastructure and operating presence in Bermuda should
attract a wholesale segment of the international telecommunications community
to utilize our switching gateway facilities, in conjunction with our Atlantica-
1 Network capacity, as part of a turnkey services and back office solution that
is more cost effective than existing options. With additional traffic volumes
from incremental hubbing activities, combined with our existing base of
traffic, we expect to negotiate favorable terms for international traffic
delivery and to reflect those low costs in rates to our collocated carrier
customers. We intend to be an international gateway in Bermuda for our target
customers.

 Target Customers

   We are focusing on providing capacity on our system to international
telecommunications service providers. Our target customer base includes many of
the larger North American carriers, South American carriers and new
telecommunications market entrants. We expect that initially the majority of
our customers will be North American and European telecommunication carriers or
their South American affiliates. Our target customers include, among others:

  . incumbent long-distance carriers,

  . competitive long-distance carriers,

  . RBOCs,

  . competitive local exchange carriers,

  . former state owned monopoly carriers,

  . new South American entrants,

  . ISPs and data CLECs,

  . wireless telephone companies,

  . cable and telephony providers, and

  . existing undersea cable systems in the region that require restoration.

   We expect that many of our potential customers that do not currently offer
international long-distance services will obtain an international long-distance
license or be allowed to offer these services as a result of deregulation. We
also expect existing international long-distance carriers to expand the areas
for which they

                                       53
<PAGE>

offer service. We believe that international connectivity will become
increasingly important to telecommunications service providers and their
customers.

 Marketing Strategy

   We intend to develop our own sales and marketing organization to promote
sales of capacity on the Atlantica-1 Network. We intend to have a senior sales
manager overseeing regional sales operations in the United States, Venezuela,
Brazil and Argentina. Each regional operation will handle the direct sales
within its geographic territory, consistent with our overall pricing strategy.
We may supplement our own sales force during our initial marketing effort, and
use third party sales agents that can function in a complementary manner. We
are in discussions with operators of other new cable systems to develop a joint
marketing program that would enable us to expand the reach of our systems by
marketing and promoting capacity on each other's systems.

   We will utilize our long standing relationships, our own sales force and our
third party sales agents to identify and encourage early potential purchasers.
Our marketing strategy includes organizing capacity purchase meetings with
potential customers to elicit interest in our systems and identify and respond
to customer demands. In May 1999, we conducted an initial information meeting
in Washington, D.C., providing system features and preliminary pricing, which
attracted over 100 attendees from over 30 companies. We intend to organize
several additional meetings during our system development period to build
further relationships with our potential customers, and to encourage focused
one-on-one meetings to understand fully each potential customer's needs.

Network Operations Center

   We currently operate a network operations center in Bermuda to support the
BUS-1 system. In connection with the Atlantica-1 Network, we will develop an
additional network operations center in Bermuda to provide total customer
support and be responsible for the overall operation and maintenance of the
Atlantica-1 Network. We expect to provide dedicated network operations center
personnel to support capacity purchasers in all aspects of capacity usage,
performance and maintenance. Additionally, the network operations center
personnel will provide interconnection coordination and support, both
administrative and technical, and will directly manage capacity provisioning,
network performance, network maintenance and repair, and network restoration.
Network operations center personnel also will serve as a single point of
contact for customer service provisioning, interconnect coordination support,
and any billing inquiry items. The network operations center personnel will
also provide assistance to purchasers to resolve issues with their applications
and interconnect arrangements. We intend to staff the network operations center
seven days a week and 24 hours per day.

Competition

   The international telecommunications industry is extremely competitive. We
face competition from existing and planned undersea fiber optic cable systems
along each of our planned routes. We will also compete with satellite providers
and land-based cable systems. We will compete primarily on the basis of price,
availability, flexible provisioning, collocation, transmission quality and
reliability, customer service and the location of our systems. See "Risk
Factors--Competition."

 Existing and Planned Cable Systems

   Americas-1 is currently the only undersea cable system in service that
directly connects North America and South America. Americas-1 is a fully
utilized non-self-healing consortium cable system that uses other

                                       54
<PAGE>


systems for its restoration. Americas-2, a consortium cable system currently
under construction, will connect various sites in the Caribbean, North America
and South America. Americas-2 is a non-self-healing collapsed ring system and
has an expected RFS date in the fourth quarter of 1999. The system is already
fully committed for its initial capacity and allocation of its upgrade capacity
is limited to consortium members. Unlike the Atlantica-1 Network, Americas-2
will not offer city-to-city connectivity and will have limited upgrade
capability.

   There are also two other announced undersea cable systems that intend to
provide connectivity between North America and South America:

  . South American Crossing, or SAC, is a new cable system being developed by
    Global Crossing Ltd. that will link coastal countries in South America to
    Global Crossing's Mid-Atlantic Crossing in St. Croix, U.S.V.I. and Global
    Crossing's Pan American Crossing in Ft. Amador, Panama. Global Crossing
    has stated that the South American Crossing system is scheduled for
    completion in the first quarter of 2001 and will be capable of providing
    up to 1,280 Gbps of total capacity.

  . The SAm-I cable system is being developed by Telefonica Internacional
    S.A. and Tyco International Ltd. and will connect South America, Central
    America and the United States. Telefonica Internacional S.A. and Tyco
    International Ltd. have stated that the SAm-I system is scheduled for
    completion in December 2000 and will be capable of providing up to 1,280
    Gbps of total capacity.

   SAC is expected to be constructed by Alcatel or one of its affiliates, and
the SAM-I cable system is expected to be constructed by Tyco Submarine Systems
Ltd. Both of these announced systems are expected to have capacity and
technology similar to ours, although neither competitor will be operated as an
independent carriers' carrier. We believe that there will be sufficient demand
in the region to support the Atlantica-1 Network and the SAC and SAm-I undersea
cable systems. In particular we believe there will be demand for capacity from
an independent carriers' carrier. However, we expect these other systems to
receive commitments for capacity that we would have received in their absence
and we cannot assure you that there will be sufficient demand to support all of
these systems. See "Risk Factors--Competition" and "--Sales of Capacity;
Realization of Other Revenues."

 Satellite Transmission

   The Atlantica-1 Network will also face competition from existing and planned
satellite systems. When comparing cable transmission against satellite
transmission for high bandwidth and fixed network uses, we believe that cable
has several distinct advantages with respect to transmission delay and quality.
Cable transmission has a lower cost per circuit, higher capacity and longer
expected service life than satellite transmission. Satellite transmission is
generally considered to have some advantages over cable transmission with
respect to point-to-multipoint broadcast and "thin route" transmission, as
opposed to the more common point-to-point, high volume transmission for which
cable usage is considered to be preferable. Based on satellite transmission
cost and quality characteristics, we believe that satellite transmission does
not represent a viable competitor to a large capacity undersea cable system
such as the Atlantica-1 Network.

 Bermuda Telecommunications Competition

   The provision of retail telecommunications services in Bermuda is also very
competitive. Although TBI has gained market share in its first two years of
operations, our principal competitor in this market, Cable & Wireless, has
substantially greater financial, technical and marketing resources, access to
larger networks through inter-company relationships, a broader portfolio of
services, stronger name recognition and long-standing customer relationships.

TBI/E-Commerce Business

 TBI Overview

   TBI is licensed to provide a broad range of international telecommunications
services, including voice, data, video and Internet, to business, residential
and government customers in Bermuda. TBI began commercial operations in May
1997, initially providing service via satellite pending the November 1997
completion of the BUS-1 system. All services are now carried exclusively over
the BUS-1 system using satellite for restoration. In 1998, TBI became our
wholly owned subsidiary as part of a reorganization.

   In two years of operation, TBI has successfully achieved a market share in
excess of one-third of the Bermuda outbound long-distance market. TBI believes
that recent regulatory and commercial developments, including the substantial
reduction in the local access charges levied by the Bermuda Telephone Company
to the international carriers and the trend to lower international settlement
rates, will result in improved operating margins going forward.

   We believe that the prospect for growth in Bermuda is significant based on
the expected continued expansion of the reinsurance and financial business
sectors, each of which are high volume consumers of international
telecommunications services. TBI's high quality network, combined with the
introduction of enhanced data and Internet services, is expected to fuel
continued growth in higher bandwidth applications.

   We believe that we can successfully leverage our Bermuda-based facilities
by, among other things, developing a server farm where Internet and e-commerce
applications can be hosted in a secure, tax advantageous offshore environment.
Additional data services, including an Integrated Services Digital Network and
an enhanced store and forward facsimile product, are currently being tested and
commercial launch is scheduled for October 1999. We launched our corporate
calling card service in May 1999, and a calling card service targeted at the
residential market is in the final phase of implementation. Growth in sales of
TBI's debit card product is being facilitated through a distribution agreement
with the largest distributor of debit cards in Bermuda. Affinity programs have
been introduced that will leverage working relationships with various
businesses and organizations to extend attractive packages to their members and
employees, with the benefit of encouraging new growth as well as long-term
retention. TBI's customer retention rate has been over 96% per annum since
commencement of commercial service in May 1997.

   Historically, the Bermuda Telephone Company's access charges were among the
highest in the world, at $0.27 per minute and $0.24 per minute for outgoing
calls and incoming calls, respectively. TBI's interconnection expense was
recently reduced as a result of a rate reduction mandated by the Bermuda
Minister of Telecommunications and Technology to a flat rate of $0.15 per
minute as of January 1, 1999. A further reduction to $0.10 per minute became
effective on July 1, 1999, with a subsequent rate determination expected in
December 1999 based on a thorough cost study of the Bermuda Telephone Company's
operations. Significant rate rebalancing is causing a commensurate increase in
local rates to offset some of the loss in revenues from the international
carriers.

 Business Lines and Products

   TBI provides international telecommunications services for traffic
originating and terminating in Bermuda using the BUS-1 system. We offer
services similar to those available from Cable & Wireless, the incumbent
carrier. We believe that our services provide a higher technical quality at
competitive prices to consumers and businesses. TBI also offers other products
and services that were previously not available in Bermuda and supports all
products and services with strong marketing and customer service. Unlike Cable
& Wireless, TBI provides direct billing to all of its commercial customers.
TBI's product offerings include:

   Private Line Service: TBI provides dedicated point-to-point circuits for
lease on a full-time basis to commercial customers in Bermuda. As a supplement
to its traditional dedicated private line service offerings,

                                       56
<PAGE>

TBI is implementing a private line and long-distance bundled service offering
which will provide high volume users with private lines at very competitive
rates.

   Card Service: Prepaid and rechargeable card services were launched in the
summer of 1998 and can be utilized on and off Bermuda. A corporate calling card
was launched in May 1999.

   Hubbing: TBI plans to promote additional hubbing activities through its
Bermuda gateway operations by providing worldwide low cost traffic delivery via
economical satellite access to operators in more remote locations not readily
served by undersea fiber cable systems. TBI also will promote least-cost
routing services to carriers in North America and South America on terms
comparable to those available in the United States, with the additional
potential to achieve greater savings based on Bermuda's favorable tax regime.

   Data Services: We intend to launch Integrated Services Digital Network
services in October 1999. This will allow TBI to meet the service requirements
of the larger customers in the commercial segment, including high quality
access for Internet services and videoconferencing. In addition, we will offer
an enhanced store and forward facsimile product.

 The Bermuda Advantage

   We believe that Bermuda's strategic offshore location and favorable
regulatory and low-tax environment will make it a preferred operational base
for carriers and ISPs. As such, we see particular benefits of doing business in
Bermuda that enhance our strategic plan and create important competitive
advantages for our customers.

   Bermuda does not currently levy sales, income or capital gains taxes. We
believe that the tax advantages of doing business in Bermuda are significant
enough to present a competitive advantage and encourage businesses to migrate
and establish an operating presence there. With the accelerating globalization
of business and heightened competitive pressures, we believe this business
strategy will be attractive to carrier customers, particularly larger carriers
with substantial traffic volumes, as well as companies offering Internet
services, including e-commerce and web hosting services.

   Bulk Capacity Sales: We believe that certain multinational customers could
achieve tax benefits by establishing a Bermuda domiciled company to buy
transmission capacity on the Atlantica-1 Network (and other systems) and then
reselling this capacity to its affiliates on an arms' length basis. The
benefits of this arrangement will depend upon the factual circumstances and tax
planning strategies of each customer. We intend to offer these customers
capacity on Atlantica-1 and to supplement it with TBI's value-added services.

   Value-Added Services: We intend to promote various value-added offerings
through which a customer could utilize our Bermuda network and network
operations center to generate cost savings and minimize income taxes. These
offerings include e-commerce and web hosting services as well as collocation of
switches and other equipment for least-cost routing and IP-based routing.
Specific services we plan to offer are:

  . turnkey e-commerce and web hosting services, including systems for order
    processing, financial transactions, and network-based fulfillment of
    digital product,

  . broadband transmission capacity and world-class hosting facilities for
    web sites utilizing the customer's own e-commerce systems or databases
    providing service such as disaster recovery backup protection,

  . collocation of switches or other equipment to perform traditional
    circuit-switched least cost routing or IP-based routing, including
    emerging international IP-based voice services. Least-cost routing takes
    advantage of the international settlement system to identify low cost
    solutions for the one-way delivery of voice traffic made possible by the
    liberalization and deregulation of many telecommunications markets around
    the world, and

  . down-linking international satellite traffic through Bermuda, rather than
    the United States, to the same ultimate destination at substantial cost
    savings, along with the availability of other value-added services.

Regulation

   Our undersea fiber optic cable facilities and telecommunications services,
including backhaul services, may be subject to regulation in each jurisdiction
where the Atlantica-1 Network and the BUS-1 system land. We currently have in
place all of the necessary licenses to land and provide services from the BUS-1
system. In order to implement fully the Atlantica-1 Network, it may be
necessary for us to obtain authority to land the cable and to offer
telecommunications services, including backhaul, to our customers in each
jurisdiction in which the cable lands. See "Risk Factors--Government
Regulation."

 United States

   In the United States, the laws and regulations pertaining to undersea cable
systems and telecommunications services are well developed and an established
set of rules and procedures exist. We have reviewed with Alcatel our various
options with respect to the most optimal landing locations. On June 2, 1999, we
submitted a cable landing license application to the FCC seeking authority to
land and operate the Atlantica-1 Network in Tuckerton, New Jersey (next to the
landing stations for the BUS-1 system) and Boca Raton, Florida. No comments or
objections were filed with the FCC in response to this application. Although we
cannot assure you that this license application will be granted, we have no
reason to believe that we will not be successful in obtaining the necessary
cable landing station license in the United States.

   TBI's U.S. affiliate, TeleBermuda International L.L.C. ("TBI L.L.C."), was
formed in May 1996 as a limited liability company under the laws of the State
of Delaware. TBI L.L.C. holds the landing license for the BUS-1 system in the
United States issued by the FCC, as well as certain ownership and leasehold
rights with respect to BUS-1 system assets located in the United States. TBI
holds a 20% ownership interest in TBI L.L.C. and Elbac Cable Corporation
("Elbac") holds the remaining 80% ownership interest. In February 1999, TBI
L.L.C. filed an application with the FCC requesting authority for TBI to obtain
control over Elbac's interest in TBI L.L.C. Upon receipt of FCC approval, TBI
L.L.C. will become a wholly owned subsidiary of TBI, and TBI L.L.C. will
continue to hold the BUS-1 system landing license and operate the BUS-1 system
as currently licensed by the FCC.

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

 Brazil and Venezuela

   In countries such as Brazil and Venezuela with recently privatized
telecommunications industries, many of the telecommunications laws and
regulations are relatively new and still evolving. In both of these countries,
there are no current statutes or regulations regarding the landing of undersea
fiber optic cable facilities. Accordingly, we have consulted with the
appropriate regulatory authorities in Brazil (ANATEL) and Venezuela (CONATEL).
Based on these consultations, we believe that we are the first private undersea
fiber optic cable operator to request governmental approval to land an
international fiber optic cable system in either jurisdiction. These
consultations have indicated to us that the pro-competitive effects of
deregulation and the desire to attract foreign investment have created flexible
regulatory environments in Brazil and Venezuela that are receptive to projects
such as the Atlantica-1 Network.

   The need for new undersea fiber optic cable systems is particularly strong
in these countries where former monopoly providers previously controlled access
to and from the country through their ownership of international capacity on
traditional consortium cable systems. Although competition in the provision of
telecommunications services has begun to be introduced in both jurisdictions,
the former monopoly carriers continue to control the existing inventory of
available undersea fiber optic capacity that lands in each country.
Accordingly, capacity remains scarce and very expensive. Government authorities
have indicated to us that the availability of alternative systems such as the
Atlantica-1 Network is necessary in order to establish a sustainable
competitive international market capable of delivering the economic and
technological benefits of privatization and deregulation.

                                       58
<PAGE>

   Brazil: On March 2, 1999, we submitted a request to ANATEL seeking authority
to construct, land and operate the Atlantica-1 Network in Brazil. ANATEL has
informally indicated to us that they are considering three different responses
to our request:

  (1) ANATEL may decline to regulate cable landings because this activity is
      outside of its jurisdiction,

  (2) ANATEL may issue to us an "enabling act" permitting us to land our
      cable, or

  (3) ANATEL may determine that we need to register our cable as a
      telecommunications facility.

   Based on our conversations with representatives of ANATEL, we anticipate
receiving a response from ANATEL permitting us to construct, land and operate
the Atlantica-1 Network in Brazil in the near future. Although we cannot assure
you that we will have the necessary authority to land the Atlantica-1 Network
in Brazil, we believe that we will be successful in securing any necessary
approvals in a timely manner. Failure to be allowed to land our cable in Brazil
could have a material adverse effect on our business, financial condition and
results of operations.

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

   Venezuela: On March 16, 1999, we submitted a letter to CONATEL seeking
guidance on what licenses or permits from CONATEL may be necessary to land the
Atlantica-1 Network in Venezuela. In response to this letter, CONATEL informed
us in writing that no authorization or permit from CONATEL is required to
construct and land the Atlantica-1 Network in Venezuela. Based on advice
provided to us by CONATEL, we do not believe that any CONATEL permits or
concessions are necessary to operate the cable or sell capacity on the cable.
However, if CONATEL were now to determine that a permit or concession was
necessary, we believe that a permit or concession would be issued by CONATEL in
a time frame consistent with the implementation schedule for the Atlantica-1
Network. In order to provide backhaul services in Venezuela, we must obtain a
Private Network Concession, which is required under Venezuelan law to install
and operate a telecommunications network for commercial purposes. We shortly
plan to submit an application to CONATEL for this license. Although we cannot
assure you that we will be granted this license, we have no reason to believe
that we will not be successful in obtaining it.

   It is our expectation that we will be able to sell or lease submarine cable
fiber optic facilities to all entities with authority to provide
telecommunications and value added network services in Venezuela. Under the
existing regulatory framework in Venezuela, only CANTV can offer international
public switched telephony services in Venezuela. However, the Concession
Agreement between the Republic of Venezuela and CANTV provides that in November
2000 the telecommunications market will be open for additional competition and
the appropriate authority will be granted to a number of companies seeking to
offer switched voice telephony services. Currently, CONATEL is issuing
authority on a routine basis to companies seeking to offer international or
domestic private network services. Thus, today we can sell our facilities to
CANTV and private network and value added service providers. Additionally, in
November 2000 we will be able to sell facilities to newly licensed switched
voice telephony providers.

 Bermuda

   On January 10, 1997, TBI was granted an international carrier license under
which it is authorized to provide a broad range of international
telecommunications services in, from, to and in transit through Bermuda. The
license is for a term of five years and is subject to renewal. TBI pays a
licensing fee based on the greater of 6% of TBI's total revenues (net of
carrier settlements) in Bermuda or 20% of TBI's profit in Bermuda. Although TBI
believes it will be able to obtain a renewal of TBI's international carrier
license, the failure to secure this renewal could have a material adverse
effect on our business, financial condition and results of operations. TBI's
international carrier license also permits TBI to land additional cables in
Bermuda subject to the prior consent of the Minister of Telecommunications and
Technology. On March 31, 1999, TBI applied for the Minister's consent to land
the Atlantica-1 Network in Bermuda. On April 7, 1999, TBI received formal
written approval from the Minister to land the Atlantica-1 Network in Bermuda.
The Minister's consent is subject to receipt of various construction licenses
and permits which are required in the ordinary course of business.

Properties

   We lease executive and administrative office space at our headquarters at 2
Carter's Bay Road, Southside, St. David's DDBX, Bermuda. We lease cable station
space in St. David's, Bermuda under a 12-year lease, which is renewable for an
additional nine-year term. We also lease cable station space in Tuckerton, New
Jersey under a lease that will expire when the BUS-1 system is retired from
service, which is expected to occur in 2022. In addition, we lease office space
in Hamilton, Bermuda, and in Canada in Markham, Ontario and Montreal.

   We intend to purchase or lease property in (1) Punta Gorda, Venezuela, (2)
Fortaleza, Brazil, (3) Rio de Janeiro, Brazil, (4) Tuckerton, New Jersey, (5)
Boca Raton, Florida, and (6) Bermuda to build new cable landing stations.

Intellectual Property and Research and Development

   We have no patents or registered trademarks. We claim trademark rights to
the following marks: "GlobeNet," "TeleBermuda," "TBI," "Atlantica," "Atlantica-
1," "Atlantica-2," "GlobeNet Communications" and "GeoReach." We expect to file
trademark applications with respect to some or all of these trademarks within
the next four months. The TBI logo, GlobeNet logo and the Atlantica logo are
our service marks.

   We are not currently conducting any material research and development
activities.

Employees

   As of October 14 , 1999, we had 53 employees. We believe that our workforce
is highly capable and motivated and that our relations with our employees are
good. There have been no material changes in the number of our employees during
the past fiscal year.

Legal Proceedings

   We are, from time to time, a party to litigation that arises in the normal
course of our business operations. We are not a party to any litigation the
resolution of which we expect to have a material adverse effect on our
business, financial condition and results of operations.

Board of Directors

directors are elected to one-year terms. Our board consists of 11 directors:
(1) one independent director who has not yet been nominated and who must be
approved by a vote of the Class B shareholders (although two of the Class B
shareholders are excluded from the nomination and approval of the independent
director), (2) one director nominated by the holders of a majority of the Class
B shares and approved by a vote of the Class B shareholders (although two of
the Class B shareholders were excluded from the nomination and approval of this
director), (3) six directors appointed by certain of the Class B shareholders,
and (4) three directors approved by a vote of the holders of our common shares,
although Class B shareholders are not permitted to vote their common shares.

 Compensation Committee

   Our board of directors has established a Compensation Committee. The purpose
of the Compensation Committee is to establish and submit to our board of
directors recommendations with respect to (1) compensation of our officers and
other key employees and (2) awards to be made under our share option and
incentive plan. Messrs. Conyers, Kedar and Murphy served on the 1998
Compensation Committee.

 Compensation of Directors

   In 1997 and 1998 we granted our directors stock options representing in the
aggregate 85,000 common shares. To date in 1999 we have granted our directors
in their capacity as directors (except Messrs. Kedar and DeMartino) stock
options representing in the aggregate 50,000 common shares. Directors did not
receive monetary compensation for their services as directors in 1997, 1998 or
to date in 1999. We have not set aside or accrued any amounts during our last
fiscal year to provide pension, retirement or similar benefits for our
directors and officers.

Indemnification of Directors and Officers

 Indemnification Agreements with Directors

   We have entered into indemnity agreements with each of our directors (other
than Mr. DeMartino, with whom we expect to enter into such an agreement in the
near future). Pursuant to the director indemnity agreements, we have agreed to
indemnify and save harmless each director, his/her heirs and legal
representatives, to the fullest extent permitted by law, against all costs,
charges, liability, damages, and expenses, including an amount paid to settle
an action or to satisfy a judgment, reasonably incurred by him/her in respect
of any civil, criminal or administrative action or proceeding to which he/she
is made a party by reason of, or in any connection with him/her, being or
having been a director if (1) the director acted in his/her capacity as a
director and (2) in the case of a criminal or administrative action or
proceeding that is enforced by a monetary penalty, the director had reasonable
grounds for believing that his/her conduct was lawful. Directors are required
to obtain our consent to any settlement of any civil, criminal or
administrative action or proceeding.

 Indemnification Agreements with Officers

   We have entered into indemnity agreements with Michael Kedar, James
Fitzgerald, Laurent Duplantie, Scott Socol, Lin Gentemann and Greg Belbeck. We
expect to enter into similar indemnity agreements with Messrs. DeMartino, Blust
and Weisbrot in the near future. Pursuant to the indemnification agreements, we
have agreed, to the fullest extent permitted by our bye-laws and applicable
law, to indemnify each indemnitee against all expenses actually and reasonably
incurred, judgments, penalties, fines and amounts paid in settlement by such
indemnitee if he/she is, or is threatened to be made, a party to any
threatened, pending, or completed action, suit, arbitration, alternate dispute
resolution mechanism, investigation, administrative hearing or any other
proceeding as a result of his/her status as an employee or officer of the
Company (1) if, in a proceeding other than a proceeding by or in the right of
the Company, he/she acted in good faith and in a manner reasonably believed to
be in our best interests and, with respect to a criminal proceeding, if he/she
had no reasonable cause to believe his/her conduct was unlawful and (2) if, in
a proceeding brought by or in the right of the Company to procure a judgment in
its favor, to the extent such indemnitee is successful, on the merits or
otherwise, provided that if the indemnitee is only partially successful in such
proceeding, we agree to indemnify him/her for such expenses actually and
reasonably incurred by him/her or on his/her behalf in connection with each
successfully resolved claim, issue or matter.

 Bye-Laws

   Our bye-laws provide that, subject to the Companies Act 1981 of Bermuda,
every director, officer and member of a committee constituted in accordance
with our bye-laws is indemnified by us against (1) all civil liabilities, loss,
damage, charge or expense incurred or suffered by him as a director, officer or
committee member while exercising his powers and discharging his duties under
the Companies Act 1981 of Bermuda and our bye-laws and (2) all liabilities
incurred by him as a director, officer or committee member in defending any
proceedings, whether civil or criminal, in which judgment is given in his favor
or in which he is acquitted, or in connection with any application under the
Companies Act 1981 of Bermuda in which relief from liability is granted to him
by the court. The indemnity extends to any person acting as a director, officer
or committee member in the reasonable belief that he has been so appointed or
elected notwithstanding any defect in such appointment or election provided,
however, that the indemnity does not extend to any matter which would render it
void pursuant to the Bermuda Act.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Securities and Exchange Commission this
indemnification is against public policy as expressed in the Securities Act of
1933 and is therefore unenforceable.

Employment Agreements with Named Executive Officers

   We entered into employment agreements with our Named Executive Officers in
October 1999. Each agreement provides for a term of employment of two years,
commencing in July 1999, and continuing thereafter for successive two-year
terms unless either we or the officer provides at least three months' notice in
advance of the expiration of the current term. Each agreement terminates
automatically upon the death of the officer, we may terminate the agreement for
cause or without cause or due to an officer's disability and the officer may
terminate the agreement for good reason or without good reason. If we terminate
an agreement without cause or due to an officer's disability, the officer
terminates the agreement for good reason, the agreement terminates due to the
officer's death or we elect not to renew an officer's employment for another
term, (1) we are required to make a lump sum payment to the officer (or the
officer's legal representatives) equal to the sum of two times the officer's
then current annual base salary, accrued bonus, certain other accrued
obligations and accrued investments under our investment plans, and (2) the
vesting of the officer's options may be accelerated. Each agreement also
restricts the officer from competing with us during the term of the officer's
employment and for a period of two years thereafter.

1998 Share Option Plan

   We adopted the 1998 Share Option and Incentive Plan on December 18, 1998.
Under this option plan, options to purchase common shares of the Company may be
granted to employees, board members and consultants or advisers to the Company
or any subsidiary. The purposes of the option plan are to enhance our ability
to attract and retain qualified individuals to advance our interests and to
provide financial incentives to these individuals to continue to serve us and
our subsidiaries and to improve our business results and earnings. The option
plan is currently administered by the board of directors of the Company which
has the authority to

                                       68
<PAGE>

set specific terms and conditions of options granted under the option plan and
to administer the option plan.
Options may be granted for a term not to exceed ten years and are not
transferable other than by will or the laws of descent and distribution, except
as otherwise approved by the board of directors.

   Each option may be exercised within the term specified in the option
agreement under which it was granted. In addition, an option may be exercised
as to vested shares within 90 days after the termination of the optionee's
employment, except that our board of directors, in its discretion, may annul
any option grant if the optionee is an employee of the Company or any
subsidiary and is terminated for cause. In the event of a termination due to an
optionee's death or disability, all options shall become exercisable and may be
exercised until the earlier of the first anniversary of such event or the
stated expiration date of the option. If our board of directors approves any
transaction that will result in a change of control of the Company, all options
shall become immediately exercisable for a period of fifteen days immediately
prior to the scheduled consummation of the event. Upon the consummation of any
such event, the option plan and all outstanding, unexercised options will
terminate unless the parties to the transaction provide otherwise.

   The exercise price of all stock options is the fair market value of the
common shares of the Company on the date of grant. The option exercise price
may be paid in cash or, in the discretion of our board of directors, by the
delivery of common shares then owned by the optionee, or, in the discretion of
our board of directors, by a combination of these methods. The option agreement
may also permit that payment of the exercise price may be made by delivering a
properly executed exercise notice to us directing that payment of the exercise
price will be made by a broker acceptable to us upon delivery of the common
shares to the broker.

   At September 30, 1999, we had outstanding under the option plan options for
223,719 common shares of the Company at a weighted average exercise price of
$9.0, of which 63,719 were exercisable. To date, options to purchase 40,281
common shares have been exercised under the option plan. Our board of directors
has the authority to grant options up to a maximum of 20% of the fully diluted
shares of the Company pursuant to a general mandate of our shareholders, which
expires annually unless re-approved.

1997 Stock Option Plan

   TBI adopted the 1997 Stock Option and Incentive Plan on September 24, 1997.
In connection with the reorganization of the TBI group of companies, the
options to purchase common shares of TBI issued under this plan were exchanged
for options to purchase our common shares. Under this option plan, options to
purchase common shares of the Company were granted to directors, executive
management, senior management and senior staff of TBI. The purposes of the
option plan were to enhance TBI's ability to attract and retain qualified
individuals to advance its interests and to provide financial incentives to
these individuals to continue to serve TBI and to improve its business and
earnings. Options granted pursuant to this option plan were granted for a term
not to exceed ten years and are not transferable other than by will or the laws
of descent and distribution.

   Each option may be exercised within the term specified in the option
agreement under which it was granted provided that all options must be
exercised within 10 years of the grant date or within 30 days of the optionee's
termination of employment with the Company for any reason other than retirement
or death, whichever occurs first. If the optionee's employment terminates
because of retirement as approved by the board of directors, the optionee may
exercise the options granted before retirement as the options vest but not
later than five years from the date of retirement. In the event of an
optionee's death, unless decided otherwise by the board of directors, the
estate of the optionee may exercise any options that had vested at the time of
the optionee's death within 12 months following the date of death. In the event
of an optionee's disability, unless decided otherwise by the board of
directors, the optionee may exercise the options granted before the
commencement of the disability as the options vest, but not later than five
years from the commencement of the disability. The exercise price of all stock
options is determined by the board of directors but may not be less than the
fair market value of the shares at the time of the grant.

   At September 30, 1999, we had outstanding under the option plan options for
156,899 common shares of the Company at a weighted average exercise price of
$8.00 per share, of which 55,059 were exercisable. To date, options to purchase
10,101 common shares have been exercised under the option plan. No options to
purchase common shares of the Company have been issued under this plan since
December 31, 1997.

Capital Structure

   The Company is authorized to issue 24,000,000 common shares and 2,000 Class
B shares. The creation of the Class B shares was authorized by amendments to
our bye-laws in June 1999 and July 1999. As of September 30, 1999, there were
17,019,660 common shares outstanding and 1,000 Class B shares outstanding. The
approval of holders of 66.6% of all common shares is required before we can
sell all or substantially all of our assets or amalgamate. Holders of Class B
shares are our only shareholders permitted to hold shares representing more
than 35% of the aggregate issued share capital of the Company at any time or
shares representing more than 35% of the votes attaching to all issued shares
of the Company at any time.

   Approval of the holders of a majority of the Class B shares is required
before we can amend our governing documents or dissolve. Moreover, pursuant to
an amended and restated securityholders' agreement (which is described below)
executed by the new investors in the private equity financing, the Company and
certain other shareholders, the approval of the holders of a majority of the
Class B shares is required before we can engage in certain transactions,
including:

  .  certain issuances of securities,

  .  declarations of dividends, distributions or redemptions,

  .  sales or leases of assets (other than in the ordinary course of
     business) constituting more than 400 STM-1 circuits of capacity or more
     than 25% of our other assets or a material interest in a material
     subsidiary, in a single transaction or series of related transactions,

  .  incurring indebtedness (other than trade payables incurred in the
     ordinary course of business and debt under Holdings' bank credit
     facility or the notes) in excess of $25 million in aggregate principal
     amount outstanding at any time,

  .  adoption of the annual budget and business plan,

  .  making equity investments, acquisitions or capital expenditures, other
     than for maintenance of assets, that exceed, in the aggregate, the
     budgeted amounts for these line items by more than 5%,

  .  amalgamations, mergers, wind-ups, reorganizations and certain other
     fundamental changes,

  .  hiring or firing our chief executive officer or certain other members of
     senior management,

  .  terminating or suspending construction under the Alcatel contract, or

  .  amending certain material contracts or licenses.

Amended and Restated Securityholders' Agreement

   In connection with the private equity financing, the Company, TBI and
certain of our affiliates entered into an amended and restated securityholders'
agreement with Michael Kedar, TeleBermuda (BVI) Limited, IHI Hydro, Inc. (one
of our former subordinated lenders and an indirect affiliate of one of the
initial purchasers of old notes), and the new investors from the private equity
financing (the new investors together with Mr. Kedar, TeleBermuda (BVI) Limited
and IHI Hydro, Inc., the "Holders").

   Pursuant to this agreement:


  .  the approval of holders of a majority of the Class B shares is required
     for certain transactions, as described above,

  .  the Holders have preemptive rights to purchase their pro rata portions
     of all new issuances by us of common shares or common share equivalents,

  .  the new investors have "drag-along" rights, pursuant to which they can
     require the other Holders to sell their stock to a third party under
     certain circumstances,


                                       73
<PAGE>

  .  the new investors and the Holders have "tag-along" rights, pursuant to
     which they can participate in sales to third parties under certain
     circumstances, and

  .  the new investors have "rights of first refusal" with respect to shares
     held by each other new investor.

   The agreement also provides that the Holders will be provided access to
certain of our financial and operating information prior to a qualified public
offering of $150 million ($100 million if agreed to by holders of a majority of
the Class B shares held by the new investors) in gross proceeds to us in either
the United States or Canada. Finally, the agreement places certain restrictions
on Mr. Kedar's ability to sell, directly or indirectly, his interests in the
Company and on his ability to compete with the Company, TBI or their various
subsidiaries for two years after the termination of his employment with us. In
addition, Jeffrey Conyers and certain members of senior management are parties
to the agreement for certain limited purposes, including restricting senior
management's ability to sell their interests in the Company.

Registration Rights Agreement

   Pursuant to a registration rights agreement among the Company, the new
investors in the private equity financing and certain holders of common shares
(including certain members of senior management), the new investors have the
right to require that we file up to three registration statements for the
resale of their shares in the United States and/or Canada within six months
after the completion of a qualified underwritten public offering of common

million, and the shareholders who are a party to this agreement have, subject
to customary cutback provisions, the right to participate in any registration
statement filed by us after the qualified public offering.

                              CERTAIN TRANSACTIONS

   We have entered into the transactions described below with our officers,
directors or five percent shareholders or entities affiliated with our
officers, directors or five percent shareholders. See also "Management" for a
discussion of indemnity agreements entered with our officers and directors and
employment agreements entered with our Named Executive Officers.

   On September 15, 1997, TBI entered into a consulting services arrangement
with First Bermuda Securities Limited, of which Jeffrey Conyers is the Chief
Executive Officer. Under the arrangement as amended on March 23, 1999, First
Bermuda Securities Limited will, among other things, (1) assist TBI in the
development of a business plan and with regulatory compliance matters, (2)
provide advice with respect to strategic alternatives and ongoing regulatory
issues and (3) assist in the Atlantica-1 Network financing efforts in Bermuda.
First Bermuda Securities Limited will receive a fee of $6,250 per month for its
services through December 31, 1999.

   In connection with our repurchase of common shares on August 9, 1999, First
Bermuda Securities Limited served as our repurchase agent. First Bermuda
Securities Limited received customary fees for its services.

   Linda Dougherty, one of our directors, is a Vice President of TD Capital
Group Limited, which is an affiliate of one of the initial purchasers of the
old notes. An affiliate of TD Capital Group Limited had previously loaned $9.5
million to us in the form of secured subordinated loans with warrants to
acquire common shares of the Company. This affiliate exercised all its warrants
applying the $9.5 million principal amount of its subordinated loans and the
$1.9 million in accrued interest as the exercise consideration. TD Capital
Group Limited's affiliate used to own a majority of our Class A shares by
virtue of its subordinated loans and is a party to an amended and restated
securityholders' agreement entered in connection with the private equity
financing. TD Capital Group Limited's affiliate is also a party to the
registration rights agreement entered into in connection with the private
equity financing.

   Another affiliate of TD Capital Group Limited received customary fees for
serving as an initial purchaser of the old notes, as the financial advisor and
placement agent in connection with the private equity financing and as the
arranger and administrative agent in connection with Holdings' bank credit
facility.

   On August 26, 1998, we loaned $1,292,000 (CAD$2,000,000) to Mr. Kedar, our
then Chairman and Chief Executive Officer. Mr. Kedar used the proceeds of the
loan to invest in a joint venture with a third party carrier. The loan to Mr.
Kedar, and his participation in the joint venture, were conditional on the
third party carrier granting an option in favor of TBI to acquire an equity
interest in the third party carrier's Canadian operations. The option was
exercisable until November 30, 1998 for a 20% equity interest in the Canadian
operations at an exercise price of $7,445,000 (CAD$11,525,000) (applying the
August 26, 1998 exchange rate). As a result of our later decision to pursue the
development of the Atlantica-1 Network, TBI elected not to exercise the option.
Subsequent to year-end 1998, the loan to Mr. Kedar and all interest thereon was
repaid in full.

                         HOLDINGS' BANK CREDIT FACILITY

   On July 14, 1999, Holdings entered a credit facility with Toronto Dominion
(Texas) Inc., as administrative agent for the lenders and issuer of letters of
credit, Credit Suisse First Boston, as syndication agent for the lenders, and
TD Securities (USA) Inc., as arranger.

The Facilities

   The credit facility consists of $390 million of term facilities and a $10
million revolving credit facility, as follows:

<TABLE>
   <S>                    <C>
   Working Capital Loan:   $ 10 million senior secured working capital revolver.
   Term A Loan:            $ 60 million senior secured multiple draw term loan.
   Term B Loan:            $ 80 million senior secured multiple draw term loan.
   Term C Loan:            $150 million senior secured multiple draw term loan.
   Term D Loan:            $100 million senior secured single draw term loan.
</TABLE>

   The term C loan is subject to reduction in the event that we decide not to
exercise our option in our contract with Alcatel to build the secondary strand
of the Rio extension. Holdings may also request an additional facility of up to
$50 million to be available after the actual date of commercial operation on
terms no more restrictive than the terms of the other facilities. This
additional facility is subject to lender approval and restrictions imposed
relating to the Alcatel guarantee.

Use of Credit Facility Proceeds

   The proceeds from borrowings under the credit facility will be used together
with the proceeds that we received from the private offering of old notes and
the private equity financing to fund, among other things, the development of
the Atlantica-1 Network, working capital requirements, including the payment of
interest on the notes, and capital expenditures.

Availability of Funds Under the Credit Facility

   Availability of funds under the credit facility is subject to certain terms
and conditions. In addition, the term A loan is subject to a maximum of 5.0x
total debt leverage ratio of TBI and the term C loan is limited (1) unless and
until we elect to exercise our option to build the Rio extension and (2) by,
among other things, sales of capacity on the Atlantica-1 Network and/or the
provision of the Alcatel guarantee. See "--Alcatel Guarantee and Reimbursement
Agreement." On September 10, 1999, Holdings borrowed $100 million under the
term D loan.

Maturity of the Credit Facility

   Except with respect to the term D loan, loans under the credit facility will
mature on June 30, 2005. The term D loan will mature on September 30, 2005.
There is no required amortization of the working capital loan prior to
maturity. Loans under terms A, B and C will amortize in eight semi-annual
installments commencing on December 31, 2001 and the term D loan will require
minimal amortization prior to maturity.

Prepayments

   We are able to prepay outstanding loans under terms A, B and C and the
working capital loan at our option at any time without premium or penalty
(other than break funding payments), and the term D loan at
any time subject to a prepayment fee for payments prior to the third
anniversary of the credit facility (and subject to break funding payments), in
each case subject to certain notice and minimum prepayment

                                       76
<PAGE>

requirements. In addition, we are required to make mandatory prepayments of
outstanding loans, which will permanently reduce availability, in an amount
equal to:

  .  50% of excess cash flow (100% in the event that we are in default under
     the credit facility or in breach of certain financial covenants); plus

  .  50% of the net cash proceeds from any equity offering, with exceptions
     for the private equity financing, additional equity proceeds of up to
     $10 million, certain capital expenditures and other investments and for
     building certain extensions of our network;

  .  the net cash proceeds from permitted future debt offerings, with certain
     exceptions, including debt incurred for building certain extensions of
     our network;

  .  the net cash proceeds from permitted asset sales, excluding sales of
     capacity, above a minimum threshold amount and subject to a six-month
     reinvestment period; and

  .  the net insurance proceeds related to a damaged or destroyed segment of
     the Atlantica-1 Network that is not rebuilt or repaired.

   Notwithstanding the above, lenders under the term D loan are able to decline
these prepayments, in which case the amounts that would have been applied to a
prepayment of these lenders' term D loans will instead be applied to a
prepayment of loans under terms A, B and C until these loans are paid in full
and then to the working capital loan.

Interest Rates

   Borrowings under the loans under terms A, B and C and the working capital
loan bear interest at an initial rate per annum of LIBOR plus 3.50%, subject to
reductions down to LIBOR plus 3.00% based upon amounts outstanding or at an
alternate rate equal to the greater of the administrative agent's prime rate
and the federal funds effective rate plus 0.50% (the "ABR"), plus 2.50%,
subject to reductions down to ABR plus 2.00% based upon amounts outstanding.
Loans under term D bear interest at a rate of LIBOR plus 4.00% or ABR plus
3.00%. The default rate under the credit facility is 2.00% above the otherwise
applicable rate.

Guarantees

   The obligations under the credit facility are guaranteed by all of Holdings'
present and future direct and indirect subsidiaries.

Security

   The obligations under the credit facility are secured by substantially all
of the assets of Holdings and of its present and future direct and indirect
subsidiaries, including the capital stock of these subsidiaries. The
obligations under the credit facility are also secured by a pledge by us of the
shares of Holdings and certain other assets. Pursuant to this pledge agreement,
we agreed to certain restrictions, including restrictions on our ability to
incur additional indebtedness, create liens, make investments, make capital
expenditures, lease property, merge or transfer assets. In addition, we agreed
until the commercial operation date of the Atlantica-1 Network to limit our
business activities to our ownership of Holdings, activities related to the
notes and incidental activities.

Conditions

   There are conditions precedent to initial borrowings under the credit
facility (except the funding into escrow of borrowings under the term D loan),
including (1) that the net proceeds from the private offering of old notes and
the private equity financing have been spent, and (2) the perfection of all
collateral not previously perfected, establishment of any remaining waterfall
and lockbox accounts, receipt of any remaining guarantees and payment of all
fees and expenses. In addition, all borrowings are subject to satisfaction of
conditions customarily found in credit agreements for similar financings,
including all representations being true and complete, and meeting certain
construction milestones.


                                       77
<PAGE>

Negative Covenants

   The credit facility contains customary restrictive covenants, including
covenants that limit, subject to certain exceptions, our subsidiaries' ability
to:

  .  incur indebtedness or issue guarantees;

  .  grant liens;

  .  sell assets;

  .  make investments;

  .  enter into additional contracts;

  .  make certain capital expenditures;

  .  declare and pay dividends or make distributions;

  .  make certain restricted payments;

  .  enter into transactions with affiliates;

  .  abandon the Atlantica-1 Network;

  .  enter into unrelated activities;

  .  make material amendments to key documents; and

  .  make alterations to the Atlantica-1 Network.

   As described above under "--Security," the pledge agreement pursuant to
which we pledged our shares in Holdings to secure the obligations under the
credit facility contains negative covenants applicable to us.

Events of Default

   The credit facility provides that the occurrence of certain events
constitute, subject in certain cases to notice and grace periods, events of
default. The events of default found in the credit facility include many of
those customarily found in credit agreements for similar financings, including:

  .  default under Atlantica-1 Network contracts;

  .  suspension of construction;

  .  change of control;

  .  breach of the minimum cumulative capacity revenue covenant;

  .  failure to complete the Atlantica-1 Network by a specified date; and

  .  certain declines in the rating of the parent of Alcatel providing the
     Alcatel guarantee.

Alcatel Guarantee and Reimbursement Agreement

   The ultimate parent company of Alcatel has agreed, at the election of
Holdings, to initially guarantee $100 million of the term C loan, subject to
adjustment based upon the amount owed to Alcatel under the Alcatel contract up
to a maximum of $150 million. The guarantee will be reduced by (1) the amount
of sales of capacity on a dollar for dollar basis meeting specified down
payment requirements, as and when qualified contracts for these sales are
executed, and (2) revenue from capacity sales agreements that are not qualified
capacity sales agreements, in each case such reductions to occur when there has
been an increase of at least $1 million in such amounts.

   Holdings will, pursuant to the related reimbursement agreement, reimburse
Alcatel's ultimate parent company all amounts paid by it to the banks under the
guarantee and interest will accrue on the amount paid at the default rate under
the credit facility. The reimbursement agreement specifies restrictions on (1)
the incurrence by Holdings and our subsidiaries of indebtedness in excess of
$500 million in the aggregate, (2) payment of principal under the notes, and
(3) the granting of liens by Holdings and its subsidiaries other than in
respect of Holdings' bank credit facility and up to $50 million in principal
amount of purchase money debt. Holdings has the right, subject to limitations
in the credit facility, to prepay amounts outstanding under the reimbursement
agreement at any time and from time to time, in whole or in part, without
penalty or premium. Holdings is obligated to cause its subsidiaries to
guarantee the obligations under the reimbursement agreement and to grant a lien
on certain of their interests after the termination of the credit facility.

                                       78
<PAGE>

Blockage Events

   In the event of and during the continuance of a blockage event under
Holdings' bank credit facility, Holdings will be prohibited from paying to us
the funds that would otherwise have been made available to make scheduled
interest payments on the notes. A "blockage event" is defined as a payment
default under the credit facility, an event of bankruptcy with respect to
Holdings, the Company, any subsidiary of Holdings or, for a period of time,
Alcatel, and certain other events of default under the credit facility,
including an event of default resulting from the failure to complete the
Atlantica-1 Network by June 30, 2001 (or December 31, 2001 if we exercise our
option to build the Rio extension) and an event of default arising from a
change in control of the Company. In addition, under certain circumstances
certain defaults under certain contracts relating to the Atlantica-1 Network
may constitute a blockage event.

                          DESCRIPTION OF THE NEW NOTES

General

   The form and terms of the new notes are the same as the form and terms of
the old notes, except that the new notes have been registered under the
Securities Act of 1933, will not bear legends restricting the transfer thereof,
will not be entitled to registration rights under our registration rights
agreement, and will not contain provisions relating to additional interest. We
will issue the new notes under the indenture dated as of July 14, 1999 between
us and Bankers Trust Company, as trustee. The following description is a
summary of the material provisions of the indenture. We urge you to read the
indenture because it defines your rights as holders of the new notes. The terms
of the new notes include those stated in the indenture and those made part of
the indenture by reference to the U.S. Trust Indenture Act of 1939. You may
obtain a copy of the indenture from us.

   You can find the definitions of certain terms used in this description under
the subheading "Certain Definitions." In this description, references to "we,"
"us," "our" and "the Company" refer only to GlobeNet Communications Group
Limited and not to any of its subsidiaries.

   The old notes and the new notes will constitute a single class of debt
securities under the indenture. If the exchange offer is consummated, holders
of old notes who do not exchange new notes for their old notes will vote
together with holders of the new notes for all relevant purposes under the
indenture. Accordingly, in determining whether the required holders have given
any notice, consent or waiver or taken any other action permitted under the
indenture, any old notes that remain outstanding after the exchange offer will
be aggregated with the new notes, and the holders of the old notes and the new
notes will vote together as a single class. All references in this prospectus
to specified percentages in aggregate principal amount of the notes that are
outstanding means, at any time after the exchange offer is consummated, the
percentages in aggregate principal amount of the old notes and the new notes
then outstanding.

Brief Description of the New Notes

   The new notes:

  . will be our senior unsecured obligations;

  . will be equal in right of payment to all of our future senior unsecured
    Indebtedness;

  . effectively will be subordinated in right of payment to all of our
    existing and future secured Indebtedness to the extent of the value of
    the assets securing this Indebtedness;

  . are the obligations of a holding company and will not be guaranteed by
    any of our Subsidiaries, and effectively will be subordinated to all
    existing and future Indebtedness and other liabilities and commitments
    (including trade payables and lease obligations) of our Subsidiaries; and

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

   The indenture will permit us and our Subsidiaries to incur additional
Indebtedness, including secured Indebtedness.

   As of September 30, 1999, we had no Indebtedness outstanding, other than the
notes, and our Subsidiaries had $100.0 million in debt outstanding. Further,
one of our Subsidiaries, Holdings, may incur up to an additional $350.0 million
of Indebtedness under its credit facility, defined in the indenture as the "New
Credit Facility." See "Risk Factors--Holding Company Structure."

   As of the Issue Date, all of our Subsidiaries will be Restricted
Subsidiaries. However, under certain circumstances, we may designate current
and future Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries
are not subject to any of the restrictive covenants set forth in the indenture.


                                       80
<PAGE>

Principal, Maturity and Interest

   The notes will be limited initially in aggregate principal amount of $300.0
million. We will issue the new notes in fully registered form, without coupons,
in denominations of $1,000 and integral multiples of $1,000. The new notes will
mature on July 15, 2007.

   Interest on the notes will accrue at the rate of 13% per annum and will be
payable semi-annually in arrears on each January 15 and July 15, commencing
January 15, 2000 to the persons who are registered holders on the immediately
preceding January 1 and July 1. Interest will accrue from the most recent date
to which interest has been paid on the old notes or, if no interest has been
paid, from July 14, 1999. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

Issuance of Additional Notes

   We may issue up to $150.0 million aggregate principal amount of additional
notes having terms and conditions identical to the notes (the "additional
notes"), subject to compliance with the covenants contained in the indenture
and the New Credit Facility. Any additional notes will be part of the same
issue as the notes, will vote on all matters with the notes and will be
treated, together with the new notes and the old notes, as a single class of
securities under the indenture. Unless the context otherwise requires,
references in this prospectus to the old notes or the new notes do not include
the additional notes. Additional notes are not being offered by means of this
prospectus.

Methods of Receiving Payments on the Notes

   The principal of, and premium, if any, and interest on the notes will be
payable, and the notes will be exchangeable and transferable, at the office or
agency of the Company in the City of New York maintained for these purposes.
This office initially will be the office of the trustee located at Four Albany
Street, New York, New York 10006. At our option, interest may be paid by check
mailed to the registered address of the holder.

Paying Agent and Registrar for the Notes

   The trustee will be the initial paying agent and registrar for the notes. 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 at the office or agency of the
paying agent and registrar in the City of New York maintained for these
purposes. 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 with respect to the payment of additional amounts (as
defined below).

No Sinking Fund

   The notes will not be entitled to the benefit of any sinking fund or other
mandatory redemption.

Foreign Restrictions

   There are no restrictions imposed by Bermuda law or by our charter or other
constituent documents on the rights of non-Bermuda residents or non-Bermuda
owners of the new notes to hold the new notes or to receive payments of
interest or principal under the new notes.

                                       81
<PAGE>

Optional Redemption

   On or after July 15, 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 principal amount) set forth below, plus accrued
and unpaid interest, if any, thereon to the redemption date, if redeemed
during the twelve-month period beginning on July 15 of the years indicated
below:

   Year                                                                 Price
   ----                                                               ----------
   <S>                                                                <C>

   2005..............................................................  103.250%
   2006 and thereafter...............................................  100.000%
</TABLE>

   In addition, at any time or from time to time prior to July 15, 2002, we
may redeem up to 35% of the aggregate principal amount of notes originally
issued under the indenture at a redemption price of 113% of the principal
amount thereof, plus accrued and unpaid interest, if any, thereon to the
redemption date, with the proceeds from one or more Equity Offerings; provided
that:

     (1) at least 65% of the aggregate principal amount of notes originally
  issued under the indenture remain outstanding immediately after the
  occurrence of any such redemption; and

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

   If fewer than all of the notes are to be redeemed at any time, the trustee
will select the notes to be redeemed on a pro rata basis, by lot or by such
other method as the trustee deems fair and appropriate. No notes of $1,000 or
less shall be redeemed in part. 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 thereof to be redeemed. Another note in principal amount
equal to the unredeemed portion of the original note will be issued in the
name of the holder thereof 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.

Optional Tax Redemption

   The notes will be subject to redemption, at our option, in the event that
we become obligated to pay any additional amounts (as defined below) as a
result of a change in any laws or regulations of any Taxing Authority or a
change in any official position regarding the application or interpretation
thereof, that is publicly announced or becomes effective on or after the Issue
Date. Upon the occurrence of any such tax change, we may, at any time prior to
90 days after such tax change, redeem all, but not part, of the notes at a
price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date. We will give written notice of any
such redemption not less than 30 nor more than 60 days prior to the redemption
date.

Payment of Additional Amounts

   All payments made by or on behalf of us on or with respect to the notes
will be made free and clear of and without withholding of or deduction for or
on account of any present or future tax, duty, levy, impost, assessment or
other governmental charge (including any interest or penalties with respect
thereto) imposed or levied by or on behalf of any jurisdiction or any
political subdivision thereof or by any authority or agency therein or thereof
having power to tax (referred to below as "Taxes"), unless the withholding or
deduction of such Taxes is required by law.

   If the Company or any other payor is required to withhold or deduct any
amount on account of Taxes from any payment made on or with respect to the
notes, we or such other payor will:

     (1) make such withholding or deduction;

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

                                      82
<PAGE>

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

     (4) furnish to the holders, within 30 days after the date the payment of
  any Taxes is due, upon request certified copies of tax receipts evidencing
  such payment by us or such other payor;

     (5) indemnify and hold harmless each holder, other than an excluded
  holder, from (a) any Taxes paid by such holder as a result of payments made
  on or with respect to the notes, (b) any liability, including penalties,
  interest and expenses, arising therefrom or with respect thereto and (c)
  any Taxes imposed with respect to any reimbursement under (a) or (b), but
  excluding any such taxes described in (i)(a) immediately below; and

     (6) at least 30 days prior to each date on which any additional amounts
  are payable, we will deliver to the paying agent (if not the Company) an
  officers' certificate stating the amounts so payable and such other
  information necessary to enable the paying agent to pay such additional
  amounts to holders on the payment date.

   Notwithstanding the foregoing, we or a successor corporation shall not be
required to make any payment to a holder of additional amounts for or on
account of:

     (i) Any tax, assessment or other governmental charge that would not have
  been imposed but for (a) the existence of any present or former connection
  between such holder (an "excluded holder") (or between a fiduciary,
  settlor, beneficiary or partner of, or possessor of a power over such
  holder, if such holder is an estate, trust or partnership) and the taxing
  jurisdiction or any political subdivision or territory or possession
  thereof or area subject to its jurisdiction (other than the holding of a
  new note or the receipt of payments or exercise of rights thereunder),
  including, without limitation, such holder (or such fiduciary, settlor,
  beneficiary, partner or possessor) being or having been a citizen or
  resident thereof or being or having been present or engaged in a trade or
  business therein or having or having had permanent establishment therein,
  (b) the presentation of a new note, where presentation is required, for
  payment on a date more than 30 days after (x) the date on which such
  payment became due and payable or (y) the date on which payment thereof is
  duly provided for, whichever occurs later (except to the extent that the
  holder of such new note would have been entitled to additional amounts in
  respect of such Taxes on presenting such new note for payment on any date
  prior to such date), or (c) the presentation of a new note for payment in
  Bermuda or any political subdivision thereof or therein, unless such new
  note could not have been presented for payment elsewhere;

     (ii) Except as otherwise provided, any estate, inheritance, gift, sales,
  transfer, personal property or similar tax, assessment or other
  governmental charge;

     (iii) Any tax, assessment or other governmental charge that is imposed
  or withheld by reason of the failure by the holder or the beneficial owner
  of the note to comply with a written request of the Company addressed to
  the holder and made at least 60 days prior to the first payment date with
  respect to which the Company or any successor corporation shall apply this
  clause (iii), (a) to provide information, documents or other evidence
  concerning the nationality, residence or identity of the holder or such
  beneficial owner or (b) to make and deliver any declaration or other
  similar claim (other than a claim for refund of a tax, assessment or other
  governmental charge withheld by the Company) or satisfy any information or
  reporting requirements, which, in the case of (a) or (b), is required or
  imposed by a statute, treaty, regulation or administrative practice of the
  taxing jurisdiction as a precondition to exemption from all or part of such
  tax, assessment or other governmental charge, provided, however, that the
  limitations on the Companys or any successor corporations obligation to pay
  additional amounts set forth in clauses (a) and (b) above shall not apply
  if the provision of the information, documentation, declaration or other
  evidence or reporting described in such clauses (a) and (b) would be
  materially more onerous, in form, in procedure or in the substance of
  information disclosed, to a holder or beneficial owner of a note than
  comparable

                                       83
<PAGE>

  information or other applicable reporting requirements imposed or provided
  for under United States tax law (such as Internal Revenue Service Form 1001
  or W-8BEN); or

     (iv) Any combination of items (i), (ii) and (iii) above.

   Whenever in the indenture there is mentioned, in any context, the payment of
principal, premium, if any, redemption price, Change of Control Payment, offer
price and interest, or any other amount payable under or with respect to any
note, such mention shall be deemed to include mention of the payment of
additional amounts to the extent that, in such context, additional amounts are,
were or would be payable in respect thereof.

Change of Control

   If a Change of Control occurs, each holder of notes will have the right to
require the Company to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of that holder's notes pursuant to the offer
described below (the "Change of Control Offer"). In the Change of Control
Offer, the Company will offer to repurchase notes at a purchase price in cash
equal to 101% of the aggregate principal amount of notes repurchased plus
accrued and unpaid interest, if any, thereon to the date of purchase (the
"Change of Control Payment"). Within 30 days following any Change of Control,
the Company will mail a notice to each holder (with a copy to the trustee)
describing the transaction or transactions that constitute the Change of
Control and offering to repurchase notes on a date specified in such notice
(the "Change of Control Payment Date"), which date shall be no earlier than 30
days and no later than 60 days from the date such notice is mailed, pursuant to
the procedures required by the indenture and described in such notice. The
Company will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of the
notes as a result of a Change of Control.

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

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

     (2) deposit with the paying agent an amount equal to the Change of
  Control Payment in respect of all notes or portions thereof 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 thereof being purchased by the
  Company.

   The paying agent will promptly mail to each holder of notes so tendered the
Change of Control Payment for such notes, and the trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each holder
another note equal in principal amount to any unpurchased portion of the notes
surrendered, if any; provided that each such additional note will be in a
principal amount of $1,000 or an integral multiple thereof. The Company 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 the Company to make a Change of
Control Offer following a Change of Control will be applicable regardless of
whether or not any other provisions of the indenture are applicable. Except as
described above with respect to a Change of Control, the indenture does not
contain provisions that permit the holders of the notes to require that the
Company repurchase or redeem the notes in the event of a takeover,
recapitalization or similar transaction.

   The New Credit Facility contains prohibitions of certain events with respect
to the Company, as guarantor thereunder, including events that would constitute
a Change of Control. If a Change of Control Offer is made, there can be no
assurance that the Company will have sufficient funds to purchase all of the
notes tendered by holders seeking to accept the Change of Control Offer. The
New Credit Facility restricts such a purchase of

                                       84
<PAGE>

notes by the Company prior to repayment in full in cash of Indebtedness
outstanding under the New Credit Facility. Accordingly, any Change of Control
Offer would require the approval of the lenders thereunder. In addition, a
Change of Control may be an event of default under the New Credit Facility or
other indebtedness of the Company that may be incurred in the future.
Accordingly, the right of the holders of the notes to require the Company to
repurchase the notes may be of limited value if the Company cannot obtain the
required approval under the New Credit Facility. There can be no assurance that
in the event of a Change of Control the Company will be able to obtain the
necessary consents to consummate a Change of Control Offer. The failure of the
Company to make or consummate the Change of Control Offer or pay the applicable
Change of Control purchase price when due would result in an Event of Default
and would give the trustee and the holders of the notes and additional notes,
if any, the rights described under "Events of Default and Remedies."

   In addition, the exercise by the holders of notes of their right to require
the Company to repurchase the notes upon a Change of Control could cause a
default, even if the Change of Control itself does not, due to the financial
effect of such repurchases on the Company. Finally, the Company's ability to
pay cash to the holders of notes upon a repurchase may be limited by the
Company's then existing financial resources. See "Risk Factors--Financing
Change of Control Offer."

   The Company 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 set
forth in the indenture applicable to a Change of Control Offer made by the
Company and purchases all notes validly tendered and not withdrawn under such
Change of Control Offer.

   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 the Company 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 the Company to
repurchase such notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.

Certain Covenants

 Incurrence of Indebtedness and Issuance of Preferred Stock

   The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, enter into any
guarantee of or otherwise become directly or indirectly liable, contingently or
otherwise (collectively, incur), with respect to any Indebtedness (including
Acquired Debt), other than Permitted Indebtedness, and the Company will not
issue any Disqualified Stock and will not permit any of its Restricted
Subsidiaries to issue any Disqualified Stock or shares of preferred stock,
except, that the Company or any Guarantor may incur Indebtedness (including
Acquired Debt) and issue Disqualified Stock if either:

     (1) the Consolidated Leverage Ratio of the Company is less than 5.5 to
  1.0 (prior to July 15, 2002), or 5.0 to 1.0 (subsequent to July 15, 2002);
  or

     (2) the Consolidated Capital Ratio of the Company is less than 2.5 to
  1.0.

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


                                       85
<PAGE>

   For purposes of determining compliance with any restriction on the
incurrence of Indebtedness denominated in a currency other than U.S. dollars,
the U.S. dollar-equivalent principal amount of such Indebtedness incurred
pursuant thereto shall be calculated based on the relevant currency exchange
rate in effect on the date that such Indebtedness was incurred (or, in the case
of Indebtedness under a revolving credit facility, at the time of commitment),
provided that if such Indebtedness is incurred to refinance other Indebtedness
denominated in a foreign currency, and such refinancing would cause the
applicable restriction to be exceeded if calculated at the relevant currency
exchange rate in effect on the date of such refinancing, such restriction shall
be deemed not to have been exceeded so long as the principal amount of such
refinancing Indebtedness does not exceed the principal amount of such
Indebtedness being refinanced. The principal amount of any Indebtedness
incurred to refinance other Indebtedness, if incurred in a different currency
from the Indebtedness being refinanced, shall be calculated based on the
currency exchange rate applicable to the currencies in which such respective
Indebtedness is denominated that is in effect on the date of such refinancing.

   For purposes of determining any particular amount of Indebtedness under this
"Incurrence of Indebtedness and Issuance of Preferred Stock" covenant, (1)
guarantees, Liens or obligations with respect to letters of credit or other
similar instruments supporting Indebtedness otherwise included in the
determination of such particular amount shall not be included and (2) any Liens
granted pursuant to the equal and ratable provisions referred to in the "Liens"
covenant described below shall not be treated as giving rise to Indebtedness.
For purposes of determining compliance with this "Incurrence of Indebtedness
and Issuance of Preferred Stock" covenant, any other obligations of the obligor
on such Indebtedness arising under any Lien or letter of credit or other
similar instrument or obligation supporting such Indebtedness shall be
disregarded to the extent that the same secures the principal amount of such
Indebtedness.

   The accrual of interest or the accretion of accreted value will not be
deemed an incurrence of Indebtedness for the purposes of this "Incurrence of
Indebtedness and Issuance of Preferred Stock" covenant.

 Restricted Payments

   The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, make any Restricted Payment unless at the time of
and after giving effect to such Restricted Payment:

     (1) no Default or Event of Default has occurred and is continuing or
  would occur as a consequence thereof; and

     (2) the Company would, at the time of such Restricted Payment and after
  giving pro forma effect thereto, have been permitted to incur at least
  $1.00 of additional Indebtedness pursuant to 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

     (3) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments declared or made after the Issue Date (excluding
  Restricted Payments permitted by clauses (2), (3), (4) and (6) of the next
  succeeding paragraph), is less than the sum, without duplication, of

       (a) the Applicable Percentage of the Consolidated Net Income of the
    Company for the period (taken as one accounting period) from the
    beginning of the first fiscal quarter commencing after the Issue Date
    to the end of the Company's most recently ended fiscal quarter for
    which internal financial statements are available at the time of such
    Restricted Payment (or, if such aggregate cumulative Consolidated Net
    Income is a deficit, less 100% of such deficit), plus

       (b) 100% of the aggregate net cash proceeds received by the Company
    since the Issue Date as a contribution to its common equity capital or
    from the issue or sale of Equity Interests of the Company (other than
    Disqualified Stock and other than the issuance of Equity Interests in
    connection with the Private Equity Financing) or from the issue or sale
    since the Issue Date of Disqualified Stock or debt securities of the
    Company or a Restricted Subsidiary that have been converted into or
    exchanged for such Equity Interests (other than Equity Interests (or
    Disqualified Stock or debt securities) sold to a

                                       86
<PAGE>

    Subsidiary of the Company), plus the aggregate net cash proceeds
    received by the Company upon any such conversion or exchange, plus

       (c) 100% of the net reduction in Investments on and after the Issue
    Date, resulting (i) from payments of interest on Indebtedness,
    dividends, repayments of loans or advances, or other transfers of
    property (but only to the extent such interest, dividends, repayments
    or other transfers of property are not included in the calculation of
    Consolidated Net Income), in each case to the Company or any of its
    Restricted Subsidiaries from any Person (including, without limitation,
    from Unrestricted Subsidiaries of the Company) or (ii) from
    redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
    (in each case, valued as provided in the definition of Investments set
    forth below under the caption "--Certain Definitions"), in the case of
    each of (i) and (ii) not to exceed in the case of any Person the amount
    of Restricted Investments previously made by the Company or any of its
    Restricted Subsidiaries in such Person (subsequent to the Issue Date)
    and in each such case which was treated as a Restricted Payment (other
    than any such Restricted Payment that was made pursuant to the
    provisions of paragraphs (1) through (8) below).

   The preceding provisions will not prohibit the following Restricted
Payments:

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

     (2) the redemption, repurchase, retirement, defeasance or other
  acquisition of any Indebtedness of the Company subordinate to the notes or
  of any Equity Interests of the Company or any Restricted Subsidiary in
  exchange for, or out of the net cash proceeds of the substantially
  concurrent sale (other than to a Subsidiary of the Company) of, Equity
  Interests of the Company (other than Disqualified Stock); provided that the
  amount of any such net cash proceeds that are utilized for any such
  redemption, repurchase, retirement, defeasance or other acquisition shall
  be excluded from clause (3)(b) of the preceding paragraph;

     (3) the defeasance, redemption, retirement, repurchase or other
  acquisition of any Indebtedness of the Company subordinate to the notes in
  exchange for, or with the net cash proceeds from an incurrence of,
  Permitted Refinancing Indebtedness;

     (4) Investments made out of an amount not exceeding the net cash
  proceeds of one or more sales (other than to a Subsidiary of the Company)
  of Equity Interests (other than Disqualified Stock) of the Company;
  provided that the amount of any such net cash proceeds that are utilized
  for any such Investment shall be excluded from clause (3)(b) of the
  preceding paragraph;

     (5) the repurchase, redemption or other acquisition or retirement for
  value of any Equity Interests of the Company pursuant to any management
  equity subscription agreement or stock option agreement and the repurchase
  of Equity Interests of the Company from employees, officers or directors of
  the Company or any of its Restricted Subsidiaries or their authorized
  representatives upon the death, disability or termination of employment of
  such officers, directors and employees in an aggregate amount not to exceed
  $2.0 million in any calendar year (provided that unused amounts may be
  carried over to succeeding next 12 month periods, subject to a maximum of
  $4.0 million);

     (6) Investments to the extent payment for which consists of Equity
  Interests (other than Disqualified Stock) of the Company;

     (7) pro rata dividends or other distributions made by a Restricted
  Subsidiary of the Company to minority stockholders (or owners of an
  equivalent interest in the case of a Restricted Subsidiary that is not a
  corporation);

     (8) the payment, purchase, redemption or other acquisition or retirement
  of any Indebtedness of the Company that is expressly subordinated in right
  of payment to the notes at a purchase price not greater than 101% of the
  principal amount thereof, together with accrued interest, if any, thereon,
  in the event of a Change of Control, in accordance with provisions that are
  similar to the provisions described under the caption "Change of Control;"
  provided, that prior to such purchase the Company has made the Change of

                                       87
<PAGE>

  Control Offer to all holders of the notes as provided under such caption
  and has purchased all notes validly tendered for payment in connection with
  such Change of Control Offer;

     (9) the payment, purchase, redemption or other acquisition or retirement
  out of any Excess Proceeds of any Indebtedness of the Company that is
  expressly subordinated in right of payment to the notes at a purchase price
  not greater than 100% of the principal amount thereof together with accrued
  interest, if any, thereon, in the event the Company is required to make an
  Asset Sale Offer, in accordance with provisions that are similar to the
  provisions described under the caption "--Limitation on Certain Asset
  Sales;" provided, that prior to such purchase the Company has made the
  Asset Sale Offer to all holders of the notes as provided under such caption
  and has purchased out of Excess Proceeds all notes validly tendered for
  payment in connection with such Asset Sale Offer; and

     (10) other Restricted Payments in an aggregate amount not to exceed $5.0
  million;

provided, however, that no Default or Event of Default has occurred and is
continuing or will 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 the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The Fair Market Value of any assets or securities that are required to be
valued by this covenant shall be determined by the Board of Directors of the
Company whose resolution with respect thereto shall be delivered to the
trustee. The Board of Directors' determination must be based upon an opinion or
appraisal issued by an accounting, appraisal or investment banking firm of
national standing if the Fair Market Value exceeds $10.0 million. Not later
than the date of making any Restricted Payment, the Company shall deliver to
the trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting 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.

 Limitation on Certain Asset Sales

   The Company will not, and will not permit any of its Restricted Subsidiaries
to, consummate an Asset Sale unless:

     (1) the Company (or the Restricted Subsidiary, as the case may be)
  receives consideration at the time of such Asset Sale at least equal to the
  Fair Market Value of the assets or Equity Interests issued or sold or
  otherwise disposed of; and

     (2) at least 75% of the consideration received by the Company or the
  Restricted Subsidiary is in the form of cash and/or Cash Equivalents and/or
  Fiber Optic Assets, provided that (x) the amount of any Indebtedness of the
  Company (other than Indebtedness that is expressly subordinated in right of
  payment to the notes) or any Restricted Subsidiary that is assumed by the
  transferee of any such assets pursuant to an agreement that unconditionally
  releases the Company and its Restricted Subsidiaries from further liability
  related to such Indebtedness, and (y) liabilities other than Indebtedness
  for which any other Person assumes responsibility, shall in each case be
  treated as cash for purposes of this covenant.

   Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company or the Restricted Subsidiary may apply the Net Proceeds:

     (1) to permanently reduce commitments under the New Credit Facility or
  to permanently repay or retire outstanding Indebtedness incurred pursuant
  to clause (1) of the definition of "Permitted Indebtedness," or

     (2) to acquire Fiber Optic Assets.

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

                                       88
<PAGE>

   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, the Company will
make an offer (an "Asset Sale Offer") to all holders of notes and may make an
offer to all holders of other Indebtedness that is pari passu with the notes
containing provisions similar to those set forth in the indenture with respect
to offers to purchase or redeem with the proceeds of sales of assets, to
purchase the maximum principal amount of notes and such other pari passu
Indebtedness that may be purchased out of the Excess Proceeds. The offer price
in any Asset Sale Offer will be equal to 100% of principal amount plus accrued
and unpaid interest, if any, thereon to the date of purchase and will be
payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Company may use such Excess Proceeds for any purpose not
otherwise prohibited by the indenture. If the aggregate principal amount of
notes and such other pari passu Indebtedness tendered into such Asset Sale
Offer exceeds the amount of Excess Proceeds, the trustee shall select the notes
and such other pari passu Indebtedness to be purchased on a pro rata basis.
Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be
reset at zero.

   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 of the
Company whose resolution with respect thereto shall be delivered to the
trustee. The Board of Directors' determination must be based upon an opinion or
appraisal issued by an accounting, appraisal or investment banking firm of
national standing if the Fair Market Value of such assets or securities
(excluding any Fiber Optic Assets) exceeds $10.0 million.

   The New Credit Facility contains prohibitions of certain events with respect
to the Company, as a guarantor thereunder, including events that would
constitute an Asset Sale. In addition, the exercise by the holders of notes of
their right to require the Company to repurchase the notes upon an Asset Sale
could cause a default under agreements, even if the Asset Sale itself does not,
due to the financial effect of such repurchases on the Company. Finally, the
Company's ability to pay cash to the holders of notes upon a repurchase may be
limited by the Company's then existing financial resources. See "Risk Factors--
Financing Change of Control Offer".

 Liens

   The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind on any asset or property now
owned or hereafter acquired, except Permitted Liens, unless the notes are
secured equally and ratably with the obligation so secured, so long as such
obligation is so secured.

 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

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

     (1) pay dividends or make any other distributions on its Capital Stock
  to the Company or any of the Company's Restricted Subsidiaries, or with
  respect to any other interest or participation in, or measured by, its
  profits, or pay any indebtedness owed to the Company or any of the
  Company's Restricted Subsidiaries;

     (2) make loans or advances to the Company or any of the Company's
  Restricted Subsidiaries; or

     (3) transfer any of its properties or assets to the Company or any of
  the Company's Restricted Subsidiaries.

   However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

     (1) Existing Indebtedness or other agreements as in effect on the Issue
  Date and any amendments, modifications, restatements, renewals, increases,
  supplements, refundings, replacements or refinancings

                                       89
<PAGE>

  thereof, provided that such amendments, modifications, restatements,
  renewals, increases, supplements, refundings, replacement or refinancings
  are not materially more restrictive, taken as a whole, with respect to such
  encumbrances and restrictions than those contained in such Existing
  Indebtedness, as in effect on the Issue Date;

     (2) the indenture, the old notes and the new notes;

     (3) the New Credit Facility, as in effect on the date of its execution
  and as may be modified in accordance with the provisions of the commitment
  letter relating to the New Credit Facility permitting certain changes in
  connection with syndication, 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 not materially more restrictive, taken as a whole, with
  respect to such encumbrances and restrictions than those contained in the
  New Credit Facility, as in effect on the date of its execution and as
  modified in the manner described above;

     (4) applicable law or any governmental or regulatory permit or license;

     (5) any instrument governing Indebtedness or Capital Stock of, or
  agreement binding on, a Person acquired by the Company or any of its
  Restricted Subsidiaries as in effect at the time of such acquisition
  (except to the extent such Indebtedness was incurred in connection with or
  in contemplation of such acquisition), which encumbrance or restriction is
  not applicable to any Person, or the properties or assets of any Person,
  other than the Person, or the property or assets of the Person, so
  acquired, provided that, in the case of Indebtedness, such Indebtedness was
  permitted by the terms of the indenture to be incurred;

     (6) 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;

     (7) Purchase Money Indebtedness or Vendor Financing Indebtedness that
  imposes restrictions of the nature described in clause (3) of the preceding
  paragraph, provided that such obligations are permitted to be incurred
  under clause (6) or clause (7), as the case may be, of the definition of
  "Permitted Indebtedness" set forth below;

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

     (9) Permitted Refinancing Indebtedness, provided that the restrictions
  contained in the agreements governing such Permitted Refinancing
  Indebtedness are not materially more restrictive, taken as a whole, than
  those contained in the agreements governing the Indebtedness being
  refinanced;

     (10) Liens otherwise permitted to be incurred pursuant to the provisions
  of the covenant described above under the caption "--Liens" that limit the
  right of the Company or any of its Restricted Subsidiaries to dispose of
  the assets subject to such Lien;

     (11) customary limitations on the disposition or distribution of assets
  or property in joint venture agreements and other similar agreements
  entered into in the ordinary course of business; and

     (12) any encumbrance or restriction under any agreement relating to
  Indebtedness incurred by a Restricted Subsidiary of the Company permitted
  to be incurred under the covenant described above under "Incurrence of
  Indebtedness and Issuance of Preferred Stock"; provided that the Company in
  good faith determines (a) that, taken as a whole, the terms and conditions
  of any such encumbrances or restrictions are not materially less favorable
  to the holders than those in the New Credit Facility, and (b) that any such
  encumbrance or restriction will not prevent such Restricted Subsidiary from
  making dividends, distributions, loans or advances to the Company in
  amounts sufficient for the Company, together with

                                       90
<PAGE>

  amounts otherwise available to the Company, to make mandatory payments of
  principal, premium, if any, and interest and any additional amounts
  pursuant to the terms of the notes and the indenture and pursuant to the
  terms of any other Indebtedness of the Company.

   Certain restrictions under the New Credit Facility substantially limit the
payment of dividends or distributions to the Company until the New Credit
Facility is retired. See "Risk Factors--Holding Company Structure" and
"Holdings' Bank Credit Facility."

 Amalgamation, Merger, Consolidation or Sale of Assets

   The Company may not, directly or indirectly: (1) amalgamate or consolidate
or merge with or into another Person (whether or not the Company is the
surviving or continuing 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) the Company is the surviving or continuing corporation
  or (b) the Person formed by, surviving or continuing after any such
  amalgamation, consolidation or merger (if other than the Company), or to
  which such sale, assignment, transfer, conveyance or other disposition is
  made (the "Surviving Entity"), is a corporation organized or existing under
  the laws of Bermuda or the United States, any state thereof or the District
  of Columbia;

     (2) the Surviving Entity (if other than the Company) assumes all then
  existing obligations of the Company under the old notes, the new notes, the
  indenture and the registration rights agreement, pursuant to 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)
  is continuing or would occur immediately after giving effect to such
  transactions;

     (4) except in the case of the amalgamation, consolidation or merger of
  the Company with or into a Wholly Owned Restricted Subsidiary, the Company
  or the Surviving Entity will (A) immediately after such transaction after
  giving pro forma effect thereto and to any related financing transactions,
  be permitted to incur at least $1.00 of additional Indebtedness pursuant to
  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 (B) will, immediately after such transaction, have Consolidated
  Net Worth equal to or greater than the Consolidated Net Worth of the
  Company immediately preceding the transaction; and

     (5) the Company delivers to the trustee an Officers' Certificate and an
  opinion of counsel, each stating that such amalgamation, consolidation,
  merger or transfer and such supplemental indenture, if any, comply with the
  indenture.

   In addition, the Company may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person.

   Upon any amalgamation, consolidation or merger or any transfer of all or
substantially all of the assets of the Company in accordance with the
foregoing, the Surviving Entity shall succeed to and be substituted for, and
may exercise every right and power of, the Company under the indenture with the
same effect as if such successor corporation had been named therein as the
Company and the Company shall be released from its obligations under the notes
and under the indenture, except with respect to any obligations that arise
from, or are related to, such transaction.

   For purposes of the foregoing, the transfer (by assignment, sale or
otherwise) of all or substantially all of the properties and assets of one or
more subsidiaries (other than to the Company or a Wholly Owned Restricted
Subsidiary), the Company's interest in which constitutes all or substantially
all of the properties and assets of the Company shall be deemed to be the
transfer of all or substantially all of the properties and assets of the
Company.

                                       91

   This covenant shall not apply to sales, assignments, transfers, conveyances
and other dispositions of telecommunications capacity made in the ordinary
course of business by the Company or a Restricted Subsidiary.

 Transactions with Affiliates

   The Company 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
  the Company or the relevant Restricted Subsidiary than those that would
  have been obtained in a comparable transaction by the Company or such
  Restricted Subsidiary with a Person that is not an Affiliate; and

     (2) the Company 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 set forth 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; provided that if there are no disinterested members of the
    Board of Directors, the Company shall deliver an opinion as to the
    fairness to the Company of such Affiliate Transaction from a financial
    point of view issued by an accounting, appraisal or investment banking
    firm of national standing; 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 Company of such
    Affiliate Transaction from a financial point of view issued by an
    accounting, appraisal or investment banking firm of national standing.

   The following items will not be subject to the provisions of the prior
paragraph:

     (1) (a) the entering into, maintaining or performance of any employment
  contract, collective bargaining agreement, benefit plan, program or
  arrangement, related trust agreement or any other similar arrangement for
  or with any employee, officer or director heretofore or hereafter entered
  into in the ordinary course of business, including vacation, health,
  insurance, deferred compensation, retirement, savings or other similar
  plans, (b) the payment of compensation, performance of indemnification or
  contribution obligations, or an issuance, grant or award of stock, options
  or other equity-related interests or other securities, to employees,
  officers or directors in the ordinary course of business or (c) any
  transaction with an officer or director in the ordinary course of business
  not involving more than $100,000 in any one case;

     (2) Affiliate Transactions in effect or approved by the Board of
  Directors of the Company on or before the date of the indenture, including
  any amendments thereto (provided that the terms of such amendments are not
  materially less favorable to the Company than the terms of such agreement
  prior to such amendment);

     (3) transactions between or among the Company and any of the Company's
  Restricted Subsidiaries;

     (4) any sale or other issuance of Equity Interests (other than
  Disqualified Stock) of the Company;

     (5) any transaction consistent with commercially reasonable practices,
  and approved by a majority of the disinterested members of the Board of
  Directors of the Company; and

     (6) Permitted Investments or Restricted Payments that are permitted by
  the provisions of the indenture described above under the caption "--
  Restricted Payments."

                                      92
<PAGE>

 Sale and Leaseback Transactions

   The Company will not, and will not permit any of its Restricted Subsidiaries
to, enter into any sale and leaseback transaction; provided that the Company or
any of its Restricted Subsidiaries may enter into a sale and leaseback
transaction if

     (1) the Company (or such Restricted Subsidiary, as the case may be)
  could have:

       (a) incurred Indebtedness in an amount equal to the Attributable
    Debt relating to such sale and leaseback transaction pursuant to either
    of the Consolidated Leverage Ratio or Consolidated Capital Ratio tests
    set forth in the first paragraph of the covenant described above under
    the caption "--Incurrence of Indebtedness and Issuance of Preferred
    Stock"; and

       (b) incurred a Lien to secure such Indebtedness pursuant to the
    covenant described above under the caption "--Liens";

     (2) the gross cash proceeds of such sale and leaseback transaction are
  at least equal to the Fair Market Value (as determined in good faith by the
  Board of Directors of the Company and set forth in an Officers' Certificate
  delivered to the trustee) of the property that is the subject of such sale
  and leaseback transaction; and

     (3) the transfer of assets in such sale and leaseback transaction is
  treated as an Asset Sale, and the Company applies the proceeds of such
  transaction in compliance with the covenant described above under the
  caption "--Limitation on Certain Asset Sales."

 Issuances and Sales of Equity Interests in Restricted Subsidiaries

   The Company:

     (1) will not, and will not permit any of its Restricted Subsidiaries to,
  transfer, convey, sell, lease or otherwise dispose of any Equity Interests
  in any Restricted Subsidiary of the Company to any Person (other than the
  Company or a Wholly Owned Restricted Subsidiary of the Company), unless

       (a) such transfer, conveyance, sale, lease or other disposition is
    of all the Equity Interests in such Restricted Subsidiary; and

       (b) the cash Net Proceeds from such transfer, conveyance, sale,
    lease or other disposition are applied in accordance with the covenant
    described above under the caption "--Limitation on Certain Asset
    Sales;" and

     (2) will not permit any Restricted Subsidiary of the Company to issue
  any of its Equity Interests (other than, if necessary, shares of its
  Capital Stock constituting directors' qualifying shares) to any Person
  other than to the Company or a Wholly Owned Restricted Subsidiary of the
  Company (except in a transaction that complies with (1) above);

provided, however, that this covenant will not prevent any sale or issuance of
Equity Interests of a Restricted Subsidiary, and the ownership by any Person of
such Equity Interests, where such Subsidiary following such sale or issuance
becomes a Fiber Optic Joint Venture, and any Investment in such Restricted
Subsidiary remaining after giving effect to such sale or issuance would have
been permitted to be made under any one or more of the first paragraph under
the Restricted Payments covenant, clause (10) of the second paragraph of such
covenant or under clause (7) of the definition of "Permitted Investments," and
the proceeds of such sale or issuance are applied in compliance with the
"Limitation on Certain Asset Sales" covenant.

 Future Guarantees

   The Company will not permit any Restricted Subsidiary, directly or
indirectly, to guarantee any Indebtedness of the Company that is pari passu
with or subordinated to the notes, unless (1) such Restricted Subsidiary
previously has provided a Guarantee and (2) such Restricted Subsidiary waives,
and will not in any manner whatsoever claim or take the benefit or advantage
of, any rights of reimbursement, indemnity or

                                       93
<PAGE>

subrogation or any other rights against the Company or any other Restricted
Subsidiary as a result of any payment by such Restricted Subsidiary under its
Guarantee, until payment in full of the outstanding principal amount of the
notes and any premium or accrued and unpaid interest thereon then due and
owing; provided that this paragraph shall not be applicable to any guarantee of
any Restricted Subsidiary (a) that existed at the time such Person became a
Restricted Subsidiary and was not incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary or (b) of
Indebtedness incurred pursuant to clause (1) of the definition of "Permitted
Indebtedness." If the guaranteed Indebtedness is (1) pari passu with the notes,
then the guarantee of such guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Guarantee, or (2) subordinated to the notes, then the
guarantee of such guaranteed Indebtedness shall be subordinated to the
Guarantee, at least to the extent that the guaranteed Indebtedness is
subordinated to the notes.

   Any Guarantee will include provisions applicable to the Guarantor
substantially similar to the provisions described under the captions "Payment
of Additional Amounts" and "--Amalgamation, Merger, Consolidation or Sale of
Assets." Notwithstanding the foregoing, any Guarantee by any Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (and the provisions corresponding
to those described under the caption "--Amalgamation, Merger, Consolidation or
Sale of Assets" will not be applicable in the event of) (1) any sale, exchange
or transfer (including by way of merger or consolidation), to any Person not an
Affiliate of the Company, of all of the Company's and each Restricted
Subsidiary's Capital Stock in, or all or substantially all the assets of, such
Restricted Subsidiary (which sale, exchange, transfer or other transaction is
not prohibited by the indenture), (2) the legal or covenant defeasance of the
notes or satisfaction and discharge of the indenture, subject to customary
contingent reinstatement provisions, (3) the release or discharge of the
guarantee, assumption or other incurrence of liability that resulted in the
creation of such Guarantee, except a discharge or release by or as a result of
payment under such Guarantee or (4) the merger or consolidation of such
Restricted Subsidiary with and into the Company or another Subsidiary Guarantor
that is the surviving Person in such merger or consolidation.

   Each Guarantee will be limited to the maximum amount that can be Guaranteed
by such Restricted Subsidiary under applicable law without rendering the
Guarantee voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors
generally.

 Business Activities

   The Company will not, and will not permit any Restricted Subsidiary to,
engage in any business other than a Permitted Business.

 Unrestricted Subsidiaries

   The Board of Directors of the Company may designate, pursuant to a Board
Resolution, any Subsidiary (including any newly acquired or newly formed
Subsidiary) of the Company (other than Atlantica Network (Bermuda) Ltd.) to be
an Unrestricted Subsidiary so long as such Subsidiary has no Indebtedness other
than Non-Recourse Debt.

   In addition, if a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate Fair Market Value of all outstanding Investments
owned by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be an Investment made as of the time of such
designation and that designation will only be permitted if such Investment
would be permitted at that time.

   Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary
shall be evidenced to the trustee by filing with the trustee a certified copy
of the Board Resolution giving effect to such designation and an Officers'
Certificate certifying that such designation complied with the preceding
conditions.

   The Board of Directors of the Company may designate any Unrestricted
Subsidiary as a Restricted Subsidiary, provided that:

     (1) no Default or Event of Default has occurred and is continuing
  following such designation, and

                                       94
<PAGE>

     (2) the Company could incur at least $1.00 of additional Indebtedness
  (other than Permitted Indebtedness) pursuant to the first paragraph of the
  covenant described under "--Incurrence of Indebtedness and Issuance of
  Preferred Stock" (treating any Indebtedness of such Unrestricted Subsidiary
  as the incurrence of Indebtedness by a Restricted Subsidiary).

   Such redesignation will increase the amount available for Restricted
Payments under the covenant described under the caption "--Restricted Payments"
as provided therein or Permitted Investments, as applicable.

 Payments for Consent

   The Company 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 such consideration is offered to be paid and is paid to all holders of
the notes that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.

 Reports

   For so long as any notes remain outstanding, the Company will furnish to the
holders the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act. Whether or not the Company is subject to Section
13(a) or 15(d) of the Exchange Act, the Company shall furnish to the holders
and the trustee (and, following the filing of the Exchange Offer Registration
Statement or Shelf Registration Statement, as the case may be, as contemplated
by the registration rights agreement, will file with the Commission so long as
permitted under the Exchange Act and by the Commission) (i) within 90 days
after the end of each fiscal year, annual reports on Form 10-K (or any
successor form), or within 120 days if on Form 20-F (or any successor form),
containing the information required to be contained therein (or required in
such successor form) and (ii) within 45 days after the end of each of the first
three fiscal quarters of each fiscal year, reports on Form 10-Q (or any
successor form), or within 60 days if 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, with respect to, the notes;

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

     (3) failure by the Company or any of its Restricted Subsidiaries to make
  or consummate a Change of Control Offer or Asset Sale Offer, respectively,
  when required in accordance with the provisions described under the caption
  "--Change of Control," or "--Certain Covenants--Limitation on Certain Asset
  Sales," or to comply with the provisions described under the caption "--
  Certain Covenants--Amalgamation, Merger, Consolidation, or Sale of Assets";

     (4) failure by the Company or any of its Restricted Subsidiaries for 30
  days after notice to comply with the provisions described under the
  captions "--Change of Control" and "--Certain Covenants--Limitation on
  Certain Asset Sales" (except for any failure governed by the preceding
  clause (3)), or under the captions "--Certain Covenants--Restricted
  Payments" and "--Certain Covenants--Incurrence of Indebtedness and Issuance
  of Preferred Stock";

     (5) failure by the Company or any of its Restricted Subsidiaries for 60
  days after notice to comply with any of the other agreements in the
  indenture or the notes;

     (6) 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 the Company or any

                                       95
<PAGE>

  of its Restricted Subsidiaries (or the payment of which is guaranteed by
  the Company, 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 at final maturity such
    Indebtedness prior to the expiration of the grace period provided in
    such Indebtedness (a "Payment Default"); or

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

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

     (7) failure by the Company 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;

     (8) any Guarantee ceases to be in full force and effect or is declared
  null and void or a Guarantor denies that it has any further liability under
  a Guarantee, or gives notice to such effect (other than by reason of the
  termination of the indenture or the release of the Guarantee in accordance
  with the indenture) and such condition shall have continued for 30 days
  after notice of such failure; and

     (9) certain events of bankruptcy or insolvency with respect to the
  Company 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 the Company, any Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary of the Company, all notes
outstanding 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 the Company or the holders of at least 25% in principal amount of the
notes then outstanding by notice to the Company and the trustee may declare all
the notes to be due and payable immediately.

   At any time after a declaration of acceleration under the indenture, but
before a judgment or decree for payment of the money due has been obtained by
the trustee, the holders of a majority in aggregate principal amount of the
notes outstanding, by written notice to the Company and the trustee, may
rescind such declaration and its consequences if:

     (1) the Company has paid or deposited with the trustee a sum sufficient
  to pay

      . all overdue interest on all notes,

      . all unpaid principal of (and premium, if any, on) any notes
        outstanding that has become due otherwise than by such declaration
        of acceleration and interest thereon at the rate borne by the
        notes,

      . to the extent that payment of such interest is lawful, interest
        upon overdue interest and overdue principal at the rate borne by
        the notes, and

      . all sums paid or advanced by the trustee under the indenture and
        the reasonable compensation, expenses, disbursements and advances
        of the trustee, its agents and counsel; and

     (2) all Events of Default, other than the non-payment of amounts of
  principal of (or premium, if any, on) or interest on the notes that have
  become due solely by such declaration of acceleration, have been cured or
  waived. No such rescission will affect any subsequent default or impair any
  right consequent thereon.

   Notwithstanding the preceding paragraph, in the event of a declaration of
acceleration in respect of the notes because of an Event of Default specified
in clause (6) above shall have occurred and be continuing, such declaration of
acceleration shall be automatically annulled if the Indebtedness that is the
subject of such Event

                                       96
<PAGE>

of Default has been discharged or the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness, and written notice
of such discharge or rescission, as the case may be, shall have been given to
the trustee by the Company and countersigned by the holders of such
Indebtedness or a trustee, fiduciary or agent for such holders, within 30 days
after such declaration of acceleration in respect of the notes, and no other
Event of Default has occurred during such 30-day period which has not been
cured or waived during such period.

   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 notes then outstanding 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.

   Under the indenture, the Company shall be required to deliver to the trustee
annually a statement regarding compliance with the indenture. Within 10
business days of becoming aware of any Default or Event of Default, the Company
shall be required to deliver to the trustee a statement specifying such Default
or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

   No director, officer, employee, incorporator or stockholder of the Company
or any of its Subsidiaries, in such capacity, shall have any liability for any
obligations of the Company or its Subsidiaries under the notes or the
indenture, or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each holder 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

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

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

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

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

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

     (5) the Company's obligations to pay additional amounts.

   In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company and those of any Guarantor released with respect
to certain covenants that are described in the indenture ("Covenant
Defeasance") and thereafter any omission to comply with those covenants shall
not constitute a Default or Event of Default with respect to 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 with respect
to the notes.

                                       97
<PAGE>

   In order to exercise either Legal Defeasance or Covenant Defeasance:

     (1) the Company 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 thereof, in such amounts as will be
  sufficient, in the opinion of a nationally recognized firm of independent
  public accountants, to pay the principal of, and premium, if any, and
  interest on the notes then outstanding on the stated maturity or on the
  applicable redemption date, as the case may be, and the Company must
  specify whether the notes are being defeased to maturity or to a particular
  redemption date;

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

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

     (4) no Default or Event of Default shall have occurred and be continuing
  either: (a) on the date of such deposit (other than a Default or Event of
  Default resulting from the borrowing of funds to be applied to such
  deposit); or (b) 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) such 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 the Company or
  any of its Restricted Subsidiaries is a party or by which the Company or
  any of its Restricted Subsidiaries is bound;

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

     (8) the Company 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 all conditions precedent providing for Legal Defeasance or
  Covenant Defeasance have been complied with.


                                       98
<PAGE>

Satisfaction and Discharge

   The indenture will be discharged and will cease to be of further effect
(except as to surviving rights of registration of transfer or exchange of the
notes as set forth in the indenture), when:

     (1) either:

       (a) all notes that have been authenticated (except lost, stolen or
    destroyed notes that have been replaced or paid and notes for whose
    payment money has theretofore been deposited in trust and thereafter
    repaid to the Company) have been delivered to the trustee for
    cancellation; or

       (b) all notes that have not been delivered to the trustee for
    cancellation have become due and payable by reason of the making of a
    notice of redemption or otherwise or will become due and payable within
    one year and the Company has irrevocably deposited or caused to be
    deposited with the trustee as trust funds in trust solely for the
    benefit of the holders, cash in U.S. dollars, non-callable Government
    Securities, or a combination thereof, in such amounts as will be
    sufficient without consideration of any reinvestment of interest, to
    pay and discharge the entire indebtedness on the notes not delivered to
    the trustee for cancellation for principal, premium, if any, and
    accrued interest to the date of maturity or redemption;

     (2) no Default or Event of Default 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 material instrument to which the Company is a
  party or by which the Company is bound;

     (3) the Company has paid or caused to be paid all sums payable by it
  under the indenture; and

     (4) the Company has delivered irrevocable instructions to the trustee
  under the indenture to apply the deposited money toward the payment of the
  notes at maturity or the redemption date, as the case may be.

   In addition, the Company must deliver an Officers' Certificate and an
Opinion of Counsel to the trustee stating that all conditions precedent to
satisfaction and discharge have been satisfied.

Indemnification for Judgment Currency Fluctuations

   The obligations of the Company to any holder of notes shall, notwithstanding
any judgment in a currency (the "Judgment Currency") other than U.S. dollars
(the "Agreement Currency"), be discharged only to the extent that on the day
following receipt by such holder of notes or the trustee, as the case may be,
of any amount in the Judgment Currency, such holder of notes may in accordance
with normal banking procedures purchase the Agreement Currency with the
Judgment Currency. If the amount of the Agreement Currency so purchased is less
than the amount originally to be paid to such holder of notes or the trustee,
as the case may be, in the Agreement Currency, the Company will pay the
difference and if the amount of the Agreement Currency so purchased exceeds the
amount originally to be paid to such holder of notes or the trustee, as the
case may be, such holder of notes or the trustee, as the case may be, will pay
to or for the account of the Company such excess, provided that such holder of
notes or the trustee, as the case may be, shall not have any obligation to pay
any such excess as long as a Default by the Company in its obligations under
the notes or the indenture has occurred and is continuing, in which case such
excess may be applied by such holder of notes to such obligations.

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, the Company and the
trustee are permitted to amend or supplement the notes, 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 (with respect to 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;

                                       99
<PAGE>

     (2) reduce the principal of or change the fixed maturity of any note or
  alter the provisions with respect to the redemption of the notes (other
  than provisions relating to the covenants described above under the
  captions "--Change of Control" and "--Certain Covenants--Limitation on
  Certain Asset Sales");

     (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 currency 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 with respect to any note (other than a
  payment required by the provisions described above under the captions "--
  Change of Control" and "--Certain Covenants--Limitation on Certain Asset
  Sales");

     (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 the Company to make a Change of Control
  Offer at any time after the related Change of Control has occurred and the
  Company has become obligated to make and consummate such Change of Control
  Offer in accordance with the provisions of the covenant described under "--
  Change of Control"; or modify the obligation of the Company to make an
  Asset Sale Offer at any time after the related Asset Sale has been
  completed and the Company has become obligated to make and consummate such
  Asset Sale Offer in accordance with the provisions of the covenant
  described under "--Certain Covenants--Limitation on Certain Asset Sales;"
  or

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

   Notwithstanding the preceding, without the consent of any holder of notes,
the Company 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 the Company's obligations to
  holders of notes in the case of a merger, amalgamation or consolidation or
  sale of all or substantially all of the Company'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;

     (5) to add Guarantees with respect to the notes;

     (6) to comply with requirements of the Commission in order to effect or
  maintain the qualification of the indenture under the Trust Indenture Act
  of 1939; or

     (7) to issue additional notes. See "--Issuance of Additional Notes."

Concerning the Trustee

   The holders of a majority in principal amount of the notes then outstanding
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 person in the conduct of its
own affairs. Subject to such provisions, the trustee will be under no
obligation to

                                      100
<PAGE>

exercise any of its rights or powers under the indenture at the request of any
holder of notes, unless such holder shall have offered to the trustee security
and indemnity satisfactory to it against any loss, liability or expense.

Additional Information

   Anyone who receives this prospectus may obtain a copy of the indenture and
registration rights agreement without charge by writing to GlobeNet
Communications Group Limited, 2 Carter's Bay Road, Southside, St. David's,
Bermuda, Attention: General Counsel.

Governing Law

   The indenture provides that 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 thereby.

Enforceability of Judgments

   Since a majority of the assets of the Company are outside the United States,
any judgments obtained in the United States against the Company, including
judgments with respect to the payment of principal, premium, interest,
additional amounts, Change of Control Payment, offer price, redemption price or
other amounts payable under the notes may be not collectible within the United
States.

   The Company has been informed by its Bermuda counsel, Conyers Dill &
Pearman, that the laws of Bermuda permit an action to be brought in a court of
competent jurisdiction in Bermuda (a "Bermuda Court") 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 ("New York Court") that is not
impeachable as void or voidable under the internal laws of the State of New
York for a sum certain in respect of the enforcement of the indenture or the
notes if (i) the court rendering such judgment had jurisdiction over the
judgment debtor, as recognized by the Bermuda Court (and submission by the
Company in the indenture to the non-exclusive jurisdiction of the New York
Court will be sufficient for that purpose), (ii) such judgment was not obtained
by fraud or in a manner contrary to natural justice and the enforcement thereof
would not be inconsistent with public policy, as that term is applied by a
Bermuda Court, (iii) the enforcement of such judgment does not constitute,
directly or indirectly, the enforcement of such foreign revenue, expropriatory
or penal laws and (iv) the action to enforce such judgment is commenced within
the applicable limitation period. The Company has been advised by Conyers Dill
& Pearman that it knows of no reason, based upon public policy under the laws
of Bermuda for avoiding recognition of a judgment of a New York Court to
enforce the indenture or the notes.

Consent to Jurisdiction and Service

   Pursuant to the indenture, the Company has irrevocably appointed CT
Corporation System as its agent for service of process in any suit, action, or
proceeding with respect to 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 submitted to the non-
exclusive jurisdiction of any such court.

Book-Entry, Delivery and Form and Transfer

   The new notes initially will be in the form of one or more registered global
notes without interest coupons. Upon issuance, the global notes will be
deposited 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), some of which may be participating in DTC through the
Euroclear System ("Euroclear") and Cedelbank.

   Transfer of beneficial interests in any global notes will be subject to the
applicable rules and procedures of DTC and its direct or indirect participants
(including, if applicable, those of Euroclear and Cedelbank), which may change
from time to time.

                                      101
<PAGE>

   The global notes may be transferred, in whole and not in part, only to
another nominee of DTC or to a successor of DTC or its nominee in certain
limited circumstances. Beneficial interests in the global notes may be
exchanged for notes in certificated form in certain limited circumstances. See
"--Transfer of Interests in Global Notes for Certificated Notes."

   Initially, the trustee will act as paying agent and registrar. The notes may
be presented for registration of transfer and exchange at the offices of the
registrar.

 Depositary Procedures

   DTC has advised the Company 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 of the old
notes), banks, trust companies, clearing corporations and certain other
organizations, including Euroclear and Cedelbank. 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 advised the Company that, pursuant to DTC's procedures, (i) upon
deposit of the global notes, DTC will credit the accounts of the appropriate
direct participants, and (ii) DTC will maintain records of the ownership
interests of such direct participants in the global notes 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 notes.

   Investors in the global notes may hold their interests therein directly
through DTC if they are direct participants in DTC or indirectly through
organizations that are direct participants in DTC. Some investors in the global
notes may hold their interests therein directly through Euroclear or Cedelbank
or indirectly through organizations that are participants in Euroclear or
Cedelbank, or through organizations other than Euroclear and Cedelbank that are
direct participants in the DTC system. Morgan Guaranty Trust Company of New
York, Brussels office, is the operator and depository of Euroclear and
Citibank, N.A. is the operator and depository of Cedelbank (each a "Nominee" of
Euroclear and Cedelbank, respectively). Therefore, they will each be recorded
on DTC's records as the holders of all ownership interests held by them on
behalf of Euroclear and Cedelbank, respectively. Euroclear and Cedelbank must
maintain on their own records the ownership interests, and transfers of
ownership interests by and between, their own customers' securities accounts.
DTC will not maintain such records. All ownership interests in any global
notes, including those of customers' securities accounts held through Euroclear
or Cedelbank, will be subject to the procedures and requirements of 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 note to such 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
note to pledge such interest to persons or entities that are not direct
participants in DTC, or to otherwise take actions in respect of such interests,
may be affected by the lack of physical certificates evidencing such interests.
For certain other restrictions on the transferability of the notes see "--
Transfers of Interests in Global Notes for Certificated Notes."

   Except as described in "--Transfers of Interests in Global Notes for
Certificated Notes," owners of beneficial interests in the global notes will
not have notes registered in their names, will not receive physical delivery of
notes in certificated form and will not be considered the registered owners or
holders

                                      102
<PAGE>

thereof under the indenture for any purpose other than with respect to the
payment of additional amounts.

   Under the terms of the indenture, the Company and the trustee will treat the
persons in whose names the notes are registered (including notes represented by
global notes) as the owners thereof for the purpose of receiving payments and
for any and all other purposes whatsoever. Payments in respect of the
principal, premium, additional amounts, if any, and interest on global notes
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 the Company, the trustee nor any agent of the Company 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
notes or for maintaining, supervising or reviewing any of DTC's records or any
direct participant's or indirect participants records relating to the
beneficial ownership interests in any global 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 the Company that its current payment practice (for payments
of principal, interest and the like) with respect to securities such as the
notes is to credit the accounts of the relevant direct participants with such
payment on the payment date in amounts proportionate to such direct
participant's respective ownership interests in the global notes as shown on
DTC's records. Payments by direct participants and indirect participants to the
beneficial owners of the notes will be governed by standing instructions and
customary practices between them and will not be the responsibility of DTC, the
trustee or the Company. Neither the Company 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 notes, and the Company 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 notes for all purposes.

   The global notes 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 (other than indirect
participants who hold an interest in the notes through Euroclear or Cedelbank)
who hold an interest through a direct participant will be effected in
accordance with the procedures of such direct participant but generally will
settle in immediately available funds. Transfers between and among indirect
participants who hold interests in the notes through Euroclear and Cedelbank
will be effected in the ordinary way in accordance with their respective rules
and operating procedures.

   Cross-market transfers between direct participants in DTC, on the one hand,
and indirect participants who hold interests in the notes through Euroclear or
Cedelbank, on the other hand, will be effected by Euroclear's or Cedelbank's
respective nominee through DTC in accordance with DTC's rules on behalf of
Euroclear or Cedelbank; however, delivery of instructions relating to cross-
market transactions must be made directly to Euroclear or Cedelbank, as the
case may be, by the counterparty in accordance with the rules and procedures of
Euroclear or Cedelbank and within their established deadlines (Brussels time
for Euroclear and UK time for Cedelbank). Indirect participants who hold
interests in the notes through Euroclear and Cedelbank may not deliver
instructions directly to Euroclear's or Cedelbank's nominee. Euroclear or
Cedelbank will, if the transaction meets its settlement requirements, deliver
instructions to its respective nominee to deliver or receive interests on
Euroclear's or Cedelbank's behalf in the relevant global note in DTC, and make
or receive payment in accordance with normal procedures for same-day fund
settlement applicable to DTC.

   Because of time zone differences, the securities accounts of an indirect
participant who holds an interest in the notes through Euroclear or Cedelbank
purchasing an interest in a global note from a direct participant in DTC will
be credited, and any such crediting will be reported to Euroclear or Cedelbank
during the European business day immediately following the settlement date of
DTC in New York. Although recorded in DTC's accounting records as of DTC's
settlement date in New York, Euroclear and Cedelbank customers will not have

                                      103
<PAGE>

access to the cash amount credited to their accounts as a result of a sale of
an interest in a global note to a DTC participant until the European business
day for Euroclear or Cedelbank immediately following DTC's settlement date.

   DTC has advised the Company that it will take any action permitted to be
taken by a holder of notes only at the direction of one or more direct
participants to whose account interests in the global notes are credited and
only in respect of such portion of the aggregate principal amount of the notes
to which such direct participant or direct participants has or have given
direction. However, if there is an event of default under the notes, DTC
reserves the right to exchange global notes (without the direction of one or
more of its direct participants) for legended notes in certificated form, and
to distribute such certificated forms of notes to its direct participants. See
"--Transfers of Interests in Global Notes for Certificated Notes."

   Although DTC, Euroclear and Cedelbank have agreed to the foregoing
procedures to facilitate transfers of interests in the global notes among
direct participants, including Euroclear and Cedelbank, they are under no
obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. Neither the Company nor the trustee
shall have any responsibility for the performance by DTC, Euroclear or
Cedelbank or their respective direct and indirect participants of their
respective obligations under the rules and procedures governing any of their
operations.

   DTC management is aware that some computer applications, systems, and the
like for processing data that are dependent upon calendar dates, including
dates before, on, and after January 1, 2000, may encounter "Year 2000
problems." DTC has informed its participants and other members of the financial
community that it has developed and is implementing a program so that its
systems, as the same relate to the timely payment of distributions (including
principal and income payments) to securityholders, book-entry deliveries, and
settlement of trades within DTC, continue to function appropriately. This
program includes a technical assessment and a remediation plan, each of which
is complete. Additionally, DTC's plan includes a testing phase, which is
expected to be completed within appropriate time frames.

   However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors from whom DTC licenses software and hardware, and
third party vendors on whom DTC relies for information or the provision of
services, including telecommunication and electrical utility service providers,
among others. DTC has informed the industry that it is contacting (and will
continue to contact) third party vendors from whom DTC acquires services to:
(1) impress upon them the importance of such services being Year 2000
compliant; and (2) determine the extent of their efforts for Year 2000
remediation (and, as appropriate, testing) of their services. In addition, DTC
is in the process of developing such contingency plans as it deems appropriate.

   According to DTC, the foregoing information with respect to DTC has been
provided to the industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.

   The information in this section concerning DTC, Euroclear and Cedelbank and
their book-entry systems has been obtained from sources that the Company
believes to be reliable, but the Company takes no responsibility for the
accuracy thereof.

 Transfers of Interests in Global Notes for Certificated Notes

   An entire global note may be exchanged for definitive notes in registered,
certificated form without interest coupons ("certificated notes") if:

  . DTC (x) notifies the Company that it is unwilling or unable to continue
    as depositary for the global notes and the Company thereupon fails to
    appoint a successor depositary within 90 days or (y) has ceased to be a
    clearing agency registered under the Exchange Act of 1934,


                                      104
<PAGE>

  . the Company, at its option, notifies the trustee in writing that it
    elects to cause the issuance of certificated notes or

  . there shall have occurred and be continuing a default or an event of
    default with respect to the notes.

   In any such case, the Company will notify the trustee in writing that, upon
surrender by the direct and indirect participants of their interest in such
global note, certificated notes will be issued to each person that such direct
and indirect participants and the DTC identify as being the beneficial owner of
the related notes.

   Beneficial interests in global notes held by any direct or indirect
participant may be exchanged for certificated notes upon request to DTC, by
such direct participant (for itself or on behalf of an indirect participant),
to the trustee in accordance with customary DTC procedures. Certificated notes
delivered in exchange for any beneficial interest in any global note will be
registered in the names, and issued in any approved denominations, requested by
DTC on behalf of such direct or indirect participants (in accordance with DTC's
customary procedures).

   Neither the Company nor the trustee will be liable for any delay by the
holder of any global note or DTC in identifying the beneficial owners of notes,
and the Company and the trustee may conclusively rely on, and will be protected
in relying on, instructions from the holder of the global note or DTC for all
purposes.

 Same Day Settlement and Payment

   The indenture requires that payments in respect of the notes represented by
the global notes (including principal, premium, if any, interest and additional
amounts, if any) be made by wire transfer of immediately available same day
funds to the accounts specified by the holder of interests in such global note.
With respect to certificated notes, the Company will make all payments of
principal, premium, if any, interest and additional amounts, if any, by wire
transfer of immediately available same day funds to the accounts specified by
the holders thereof or, if no such account is specified, by mailing a check to
each such holder's registered address. The Company expects that secondary
trading in the certificated notes will also be settled in immediately available
funds.

                                 EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

   In connection with the issuance of the old notes, we entered into a
registration rights agreement. Under the registration rights agreement, we
agreed to:

  . use our reasonable best efforts to file a registration statement with the
    Securities and Exchange Commission for an exchange of the new notes for
    the old notes under the Securities Act of 1933 and to keep such
    registration statement effective until the closing of such exchange
    offer;

  . use our reasonable best efforts to cause the exchange offer to be
    consummated within 210 days following the original issuance of the old
    notes;

  . keep the exchange offer open for acceptance for a period of not less than
    30 days after the date notice thereof is mailed to holders of the old
    notes, or longer if required by applicable law; and

  . accept for exchange all old notes duly tendered and not validly withdrawn
    in the exchange offer in accordance with the terms of the exchange offer
    registration statement and letter of transmittal.

   As soon as practicable after the exchange offer registration statement
becomes effective, we will offer the holders of old notes who are not
prohibited by any law or policy of the Securities and Exchange Commission from
participating in this exchange offer the opportunity to exchange for their old
notes new notes registered under the Securities Act of 1933 that are
substantially identical to the old notes, except that the new notes will not
contain terms with respect to transfer restrictions, registration rights and
additional interest.

   Under limited circumstances, we will use our reasonable best efforts to
cause the Securities and Exchange Commission to declare effective a shelf
registration statement with respect to the resale of the old notes and keep the
statement effective for up to two years after the effective date of the shelf
registration statement (or one year from the effective date of the shelf
registration statement if such registration statement is filed upon the request
of an initial purchaser, as described in the third bullet point below). These
circumstances include:

  . if any changes in law or their interpretations by the staff of the
    Securities and Exchange Commission do not permit us to effect the
    exchange offer as contemplated by the registration rights agreement,

  . if the exchange offer if not consummated within 210 days after July 14,
    1999, and

  . if any initial purchaser of the old notes so requests with respect to old
    notes held by it and if such initial purchaser is not permitted pursuant
    to applicable law or interpretation of the staff of the Securities and
    Exchange Commission to participate in the exchange offer.

   Additional interest will accrue on the notes at a rate of 0.5% per annum for
the first 90-day period and 0.25% per annum for each subsequent 90-day period
in the following circumstances:

  . the exchange offer registration statement is not declared effective on or
    prior to the 180th day after July 14, 1999,

  . the exchange offer is not consummated on or prior to the 210th day after
    July 14, 1999,

  . a shelf registration statement, if required, is not declared effective on
    or prior to the 60th day after it is required to be filed, or

  . the exchange offer registration statement or shelf registration statement
    ceases to be effective after being declared effective without being
    succeeded immediately by an additional registration statement filed and
    declared effective.

   Upon the filing of the exchange offer registration statement, the
effectiveness of the exchange offer registration statement, the consummation of
the exchange offer, the effectiveness of a shelf registration

                                      121
<PAGE>


statement, or the effectiveness of a succeeding registration statement, as the
case may be, the interest rate borne by the notes from the date of such filing,
effectiveness or consummation, as the case may be, is reduced to the original
interest rate; provided, however, that, if after any such reduction in interest
rate, a different event specified in the five clauses above occurs, the
interest rate may again be increased pursuant to the foregoing provisions.

   To exchange your old notes for transferable new notes in the exchange offer,
you will be required to make the following representations:

  . any new notes will be acquired in the ordinary course of your business;

  . you have no arrangement or understanding with any person or entity to
    participate in the distribution of the new notes;

  . you are not engaged in and do not intend to engage in the distribution of
    the new notes;

  . if you are a broker-dealer that will receive new notes for your own
    account in exchange for old notes, you acquired those notes as a result
    of market-making activities or other trading activities and you will
    deliver a prospectus, as required by law, in connection with any resale
    of such new notes; and

  . you are not our "affiliate," as defined in Rule 405 of the Securities
    Act.

   In addition, we may require you to deliver information to be used in
connection with the shelf registration statement in order to have your notes
included in the shelf registration statement and benefit from the provisions
regarding additional interest described in the preceding paragraphs. A holder
who sells old notes under the shelf registration statement generally will be
required to be named as a selling securityholder in the related prospectus and
to deliver a prospectus to purchasers. Such a holder will also be subject to
the civil liability provisions under the Securities Act of 1933 in connection
with such sales and will be bound by the provisions of the registration rights
agreement that are applicable to such a holder, including indemnification
obligations.

   The description of the registration rights agreement contained in this
section is a summary only. For more information, you may review the provisions
of the registration rights agreement that we filed with the Securities and
Exchange Commission as an exhibit to the registration statement of which this
prospectus is a part.

Resale of New Notes

   Based on interpretations of the Securities and Exchange Commission staff in
no action letters issued to third parties, we believe that new notes issued
under the exchange offer may be offered for resale, resold and otherwise
transferred by you without further compliance with the registration and
prospectus delivery provisions of the Securities Act of 1933 if:

  . you are not our "affiliate" within the meaning of Rule 405 under the
    Securities Act of 1933;

  . such new notes are acquired in the ordinary course of your business; and

  . you do not intend to participate in the distribution of such new notes.

   The Securities and Exchange Commission, however, has not considered the
exchange offer for the new notes in the context of a no action letter, and we
cannot assure you that the Securities and Exchange Commission would make a
similar determination as in the no action letters issued to these third
parties.

   If you tender in the exchange offer with the intention of participating in
any manner in a distribution of the new notes, you

  . cannot rely on such interpretations by the Securities and Exchange
    Commission staff; and

  . must comply with the registration and prospectus delivery requirements of
    the Securities Act of 1933 in connection with a secondary resale
    transaction.


                                      122

   Unless an exemption from registration is otherwise available, any security
holder intending to distribute new notes should be covered by an effective
registration statement under the Securities Act of 1933 containing the selling
security holder's information required by Item 507 of Regulation S-K under the
Securities Act of 1933. This prospectus may be used for an offer to resell,
resale or other retransfer of new notes only as specifically described in this
prospectus. Only broker-dealers that acquired the old notes as a result of
market-making activities or other trading activities may participate in the
exchange offer. Each broker-dealer that receives new notes for its own account
in exchange for old notes, where such old notes were acquired by such broker-
dealer as a result market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
the new notes. Please read the section captioned "Plan of Distribution" for
more details regarding the transfer of new notes.

Terms of the Exchange Offer

   Upon the terms and subject to the conditions described in this prospectus
and in the letter of transmittal, we will accept for exchange any old notes
properly tendered and not withdrawn prior to the expiration date. We will issue
new notes in principal amount equal to the principal amount of old notes
surrendered under the exchange offer. Old notes may be tendered only for new
notes and only in integral multiples of $1,000.

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

   As of the date of this prospectus, $300,000,000 aggregate principal amount
of the old notes are outstanding. This prospectus and the letter of transmittal
are being sent to all registered holders of old notes. There will be no fixed
record date for determining registered holders of old notes entitled to
participate in the exchange offer.

   We intend to conduct the exchange offer in accordance with the provisions of
the registration rights agreement, the applicable requirements of the
Securities Act of 1933 and the Securities Exchange Act of 1934 and the rules
and regulations of the Securities and Exchange Commission. Old notes that are
not tendered for exchange in the exchange offer will remain outstanding and
continue to accrue interest and will be entitled to the rights and benefits
such holders have under the indenture relating to the notes and the
registration rights agreement.

   We will be deemed to have accepted for exchange properly tendered old notes
when we have given oral or written notice of the acceptance to the exchange
agent and complied with the applicable provisions of the registration rights
agreement. The exchange agent will act as agent for the tendering holders for
the purposes of receiving the new notes from us.

   If you tender old notes in the exchange offer, you will not be required to
pay brokerage commissions or fees or, subject to the instructions in the letter
of transmittal, transfer taxes with respect to the exchange of old notes. We
will pay all charges and expenses, other than certain applicable taxes
described below, in connecting with the exchange offer. It is important that
you read the section labeled "--Fees and Expenses" for more details regarding
fees and expenses incurred in the exchange offer.

   We will return any old notes that we do not accept for exchange for any
reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

Expiration Date

   The exchange offer will expire at 5:00 p.m., New York City time on       ,
1999, unless, in our sole discretion, we extend it.


                                      123
<PAGE>

Extensions, Delays in Acceptance, Termination or Amendment

   We expressly reserve the right, at any time or various times, to extend the
period of time during which the exchange offer is open. We may delay acceptance
of any old notes by giving oral or written notice of such extension to their
holders. During any such extensions, all old notes previously tendered will
remain subject to the exchange offer, and we may accept them for exchange.

   In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
old notes of the extension no later than 9:00 a.m., New York City time, on the
business day after the previously scheduled expiration date.

   If any of the conditions described below under "--Conditions to the Exchange
Offer" have not been satisfied, we reserve the right, in our sole discretion

  . to delay accepting for exchange any old notes,

  . to extend the exchange offer, or

  . to terminate the exchange offer,

by giving oral or written notice of such delay, extension or termination to the
exchange agent. Subject to the terms of the registration rights agreement, we
also reserve the right to amend the terms of the exchange offer in any manner.

   Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders of old notes. If we amend the exchange offer in a manner
that we determine to constitute a material change, we will promptly disclose
such amendment by means of a prospectus supplement. The supplement will be
distributed to the registered holders of the old notes. Depending upon the
significance of the amendment and the manner of disclosure to the registered
holders, we will extend the exchange offer if the exchange offer would
otherwise expire during such period.

Condition to the Exchange Offer

   Despite any other term of the exchange offer, we will not be required to
accept for exchange, or exchange any new notes for, any old notes, and we may
terminate the exchange offer as provided in this prospectus before accepting
any old notes for exchange, if the exchange offer, or the making of any
exchange by a holder of old notes, would violate applicable law or any
applicable interpretation of the staff of the Securities and Exchange
Commission.

   In addition, we will not be obligated to accept for exchange the old notes
of any holder that has not made to us the representations described under "--
Purpose and Effect of the Exchange Offer," "--Procedures for Tendering" and
"Plan of Distribution" and such other representations as may be reasonably
necessary under applicable Securities and Exchange Commission rules,
regulations or interpretations to make available to us an appropriate form for
registration of the new notes under the Securities Act of 1933.

   We expressly reserve the right to amend or terminate the exchange offer, and
to reject for exchange any old notes not previously accepted for exchange, upon
the occurrence of any of the conditions to the exchange offer specified above.
We will give oral or written notice of any extension, amendment, non-acceptance
or termination to the holders of the old notes as promptly as practicable.

   These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time or at various times in our sole
discretion. If we fail at any time to exercise any of these rights, this
failure will not mean that we have waived our rights. Each such right will be
deemed an ongoing right that we may assert at any time or at various times.

   In addition, we will not accept for exchange any old notes tendered, and
will not issue new notes in exchange for any such old notes, if at such time
any stop order has been threatened or is in effect with respect

                                      124
<PAGE>

to the registration statement of which this prospectus constitutes a part or
the qualification of the indenture relating to the notes under the Trust
Indenture Act of 1939.

Procedures for Tendering

 How to Tender Generally

   Only a holder of old notes may tender such old notes in the exchange offer.
To tender in the exchange offer, a holder must:

  . complete, sign and date the letter of transmittal, or a facsimile of the
    letter of transmittal;

  . have the signature on the letter of transmittal guaranteed if the letter
    of transmittal so requires; and

  . mail or deliver such letter of transmittal or facsimile to the exchange
    agent prior to the expiration date; or

  . comply with the automated tender offer program procedures of The
    Depository Trust Company, or DTC, described below.

   In addition, either:

  . the exchange agent must receive old notes along with the letter of
    transmittal;

  . the exchange agent must receive, prior to the expiration date, a timely
    confirmation of book-entry transfer of such old notes into the exchange
    agent's account at DTC according to the procedure for book-entry transfer
    described below or a properly transmitted agent's message; or

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

   To be tendered effectively, the exchange agent must receive any physical
delivery of the letter of transmittal and other required documents at its
address indicated on the cover page of the Letter of Transmittal prior to the
expiration date.

   The tender by a holder that is not withdrawn prior to the expiration date
will constitute an agreement between the holder and us in accordance with the
terms and subject to the conditions described in this prospectus and in the
letter of transmittal.

   The method of delivery of old notes, the letter of transmittal and all other
required documents to the exchange agent is at your election and risk. Rather
than mail these items, we recommend that you use an overnight or hand delivery
service. In all cases, you should allow sufficient time to assure delivery to
the exchange agent before the expiration date. You should not send the letter
of transmittal or old notes to us. You may request your brokers, dealers,
commercial banks, trust companies or other nominees to effect the above
transactions for you.

 How to Tender if You Are a Beneficial Owner

   If you beneficially own old notes that are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and you wish to
tender those notes, you should contact the registered holder promptly and
instruct it to tender on your behalf. If you are a beneficial owner and wish to
tender on your own behalf, you must, prior to completing and executing the
letter of transmittal and delivering your old notes, either:

  . make appropriate arrangements to register ownership of the old notes in
    your name; or

  . obtain a properly completed bond power from the registered holder of old
    notes.

   The transfer of registered ownership may take considerable time and may not
be completed prior to the expiration date.

                                      125
<PAGE>

 Signatures and Signature Guarantees

   You must have signatures on a letter of transmittal or a notice of
withdrawal (as described below) guaranteed by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States, or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934,
that is a member of one of the recognized signature guarantee programs
identified in the letter of transmittal, unless the old notes are tendered:

  . by a registered holder who has not completed the box entitled "Special
    Issuance Instructions" or "Special Delivery Instructions" on the letter
    of transmittal; or

  . for the account of a member firm of a registered national securities
    exchange or of the National Association of Securities Dealers, Inc., a
    commercial bank or trust company having an office or correspondence in
    the United States, or an eligible guarantor institution.

 When You Need Endorsements or Bond Powers

   If the letter of transmittal is signed by a person other than the registered
holder of any old notes, the old notes must be endorsed or accompanied by a
properly completed bond power. The bond power must be signed by the registered
holder as the registered holder's name appears on the old notes and a member
firm of a registered national securities exchange or of the National
Association of Securities Dealers, Inc., a commercial bank or trust company
having an office or correspondent in the United States, or an eligible
guarantor institution must guarantee the signature on the bond power.

   If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, those
persons should so indicate when signing. Unless waived by us, they should also
submit evidence satisfactory to us of their authority to deliver the letter of
transmittal.

 Tendering Through DTC's Automated Tender Offer Program

   The exchange agent and DTC have confirmed that any financial institution
that is a participant in DTC's system may use DTC's automated tender offer
program to tender. Participants in the program may, instead of physically
completing and signing the letter of transmittal and delivering it to the
exchange agent, transmit their acceptance of the exchange offer electronically.
They may do so by causing DTC to transfer the old notes to the exchange agent
in accordance with its procedures for transfer. DTC will then send an agent's
message to the exchange agent.

   The term "agent's message" means a message transmitted by DTC, received by
the exchange agent and forming part of the book-entry confirmation, to the
effect that:

  . DTC has received an express acknowledgment from a participant in its
    automated tender offer program that is tendering old notes that are the
    subject of such book-entry confirmation;

  . such participant has received and agrees to be bound by the terms of the
    letter of transmittal or, in the case of an agent's message relating to
    guaranteed delivery, that such participant has received and agrees to be
    bound by the applicable notice of guaranteed delivery; and

  . the agreement may be enforced against such participant.

 Determinations Under the Exchange Offer

   We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered old notes and
withdrawal of tendered old notes. Our determination will be final and binding.
We reserve the absolute right to reject any old notes not properly tendered or
any old notes our acceptance of which would, in the opinion of our counsel, be
unlawful. We also reserve the right to waive any

                                      126
<PAGE>

defect, irregularities or conditions of tender as to particular old notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties. Unless waived, all defects or irregularities in connection with
tenders of old notes must be cured within such time as we shall determine.
Although we intend to notify holders of defects or irregularities with respect
to tenders of old notes, neither we, the exchange agent nor any other person
will incur any liability for failure to give such notification. Tenders of old
notes will not be deemed made until such defects or irregularities have been
cured or waived. Any old notes received by the exchange agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned to the tendering holder, unless otherwise
provided in the letter of transmittal, as soon as practicable following the
expiration date.

 When We Will Issue New Notes

   In all cases, we will issue new notes for old notes that we have accepted
for exchange under the exchange offer only after the exchange agent timely
receives:

  . old notes or a timely book-entry confirmation of such old notes into the
    exchange agent's account at DTC; and

  . a properly completed and duly executed letter of transmittal and all
    other required documents or a properly transmitted agent's message.

 Return of Old Notes Not Accepted or Exchanged

   If we do not accept any tendered old notes for exchange for any reason
described in the terms and conditions of the exchange offer or if old notes are
submitted for a greater principal amount than the holder desires to exchange,
the unaccepted or non-exchanged old notes will be returned without expense to
their tendering holder. In the case of old notes tendered by book-entry
transfer into the exchange agent's account at DTC according to the procedures
described below, such non-exchanged old notes will be credited to an account
maintained with DTC. These actions will occur as promptly as practicable after
the expiration or termination of the exchange offer.

 Your Representations to Us

   By signing or agreeing to be bound by the letter of transmittal, you will
represent to us that, among other things:

  . any new notes that you receive will be acquired in the ordinary course of
    your business;

  . you have no arrangement or understanding with any person or entity to
    participate in the distribution of the new notes;

  . you are not engaged in and do not intend to engage in the distribution of
    the new notes;

  . if you are a broker-dealer that will receive new notes for your own
    account in exchange for old notes, you acquired those notes as a result
    of market-making activities or other trading activities and you will
    deliver a prospectus, as required by law, in connection with any resale
    of such new notes; and

  . you are not our "affiliate," as defined in Rule 405 of the Securities
    Act.

Book-Entry Transfer

   The exchange agent will establish an account with respect to the old notes
at DTC for purposes of the exchange offer promptly after the date of this
prospectus. Any financial institution participating in DTC's system may make
book-entry delivery of old notes by causing DTC to transfer such old notes into
the exchange agent's account at DTC in accordance with DTC's procedures for
transfer. Holders of old notes who are unable to deliver confirmation of the
book-entry tender of their old notes into the exchange agent's account

                                      127
<PAGE>

at DTC or all other documents required by the letter of transmittal to the
exchange agent on or prior to the expiration date must tender their old notes
according to the guaranteed delivery procedures described below.

Guaranteed Delivery Procedures

   If you wish to tender your old notes but your old notes are not immediately
available or you cannot deliver your old notes, the letter of transmittal or
any other required documents to the exchange agent or comply with the
applicable procedures under DTC's automated tender offer program prior to the
expiration date, you may tender if:

  . the tender is made through a member firm of a registered national
    securities exchange or of the National Association of Securities Dealers,
    Inc., a commercial bank or trust company having an office or
    correspondent in the United States, or an eligible guarantor institution,

  . prior to the expiration date, the exchange agent receives from such
    member firm of a registered national securities exchange or of the
    National Association of Securities Dealers, Inc., commercial bank or
    trust company having an office or correspondent in the United States, or
    eligible guarantor institution either a properly completed and duly
    executed notice of guaranteed delivery by facsimile transmission, mail or
    hand delivery or a properly transmitted agent's message and notice of
    guaranteed delivery:

    . setting forth your name and address, the registered number(s) of your
      old notes and the principal amount of old notes tendered,

    . stating that the tender is being made thereby, and

    . guaranteeing that, within three (3) New York Stock Exchange trading
      days after the expiration date, the letter of transmittal or
      facsimile thereof, together with the old notes or a book-entry
      confirmation, and any other documents required by the letter of
      transmittal will be deposited by the eligible guarantor institution
      with the exchange agent, and

  . the exchange agent receives such properly completed and executed letter
    of transmittal or facsimile thereof, as well as all tendered old notes in
    proper form for transfer or a book-entry confirmation, and all other
    documents required by the letter of transmittal, within three (3) New
    York Stock Exchange trading days after the expiration date.

   Upon request to the exchange agent, a notice of guaranteed delivery will be
sent you if you wish to tender your old notes according to the guaranteed
delivery procedures described above.

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw your
tender at any time prior to the expiration date.

   For a withdrawal to be effective:

  . the exchange agent must receive a written notice of withdrawal at the
    address indicated on the cover page of the letter of transmittal or

  . you must comply with the appropriate procedures of DTC's automated tender
    offer program system.

  Any notice of withdrawal must:

  . specify the name of the person who tendered the old notes to be
    withdrawn, and

  . identify the old notes to be withdrawn, including the principal amount of
    such old notes.

   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 DTC to be credited with withdrawn old notes and otherwise comply
with the procedures of DTC.

                                      128
<PAGE>

   We will determine all questions as to the validity, form, eligibility and
time of receipt of notice of withdrawal, and our determination shall be final
and binding on all parties. We will deem any old notes so withdrawn not to have
been validly tendered for exchange for purposes of the exchange offer.

   Any old notes that have been tendered for exchange but that are not
exchanged for any reason will be returned to their holder without cost to the
holder or, in the case of old notes tendered by book-entry transfer into the
exchange agent's account at DTC according to the procedures described above,
such old notes will be credited to an account maintained with DTC for the old
notes. This return or crediting will take place as soon as practicable after
withdrawal, rejection of tender or termination of the exchange offer. You may
retender properly withdrawn old notes by following one of the procedures
described under "--Procedures for Tendering" above at any time on or prior to
the expiration date.

Fees and Expenses

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

   We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or other soliciting
acceptances of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

   We will pay the cash expenses to be incurred in connection with the exchange
offer. They include:

  . Securities and Exchange Commission registration fees;

  . fees and expenses of the exchange agent and trustee;

  . accounting and legal fees and printing costs; and

  . related fees and expenses.

Transfer Taxes

   We will pay all transfer taxes, if any, applicable to the exchange of old
notes under the exchange offer. The tendering holder, however, will be required
to pay any transfer taxes, whether imposed on the registered holder or any
other person, if:

  . certificates representing 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 old notes
    tendered;

  . tendered old notes are registered in the name of any person other than
    the person signing the letter of transmittal; or

  . a transfer tax is imposed for any reason other than the exchange of old
    notes under the exchange offer.

   If satisfactory evidence of payment of any transfer taxes payable by a note
holder is not submitted with the letter of transmittal, the amount of such
transfer taxes will be billed directly to that tendering holder.

Consequences of Failure to Exchange

   If you do not exchange new notes for your old notes under the exchange
offer, you will remain subject to the existing restrictions on transfer of the
old notes. In general, you may not offer or sell the old notes unless they are
registered under the Securities Act of 1933, or if the offer or sale is exempt
from registration under the Securities Act of 1933 and applicable state
securities laws. Except as required by the registration rights

                                      129
<PAGE>

agreement, we do not intend to register resales of the old notes under the
Securities Act of 1933. See "Risk Factors--Failure to Properly Tender Old Notes
in Exchange Offer."

Accounting Treatment

   We will record the new notes in our accounting records at the same carrying
value as the old notes, which is the aggregate principal amount of the old
notes, as reflected in our accounting records on the date of exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes in
connection with the exchange offer. The expenses of the exchange offer incurred
up to June 30, 1999 have been accrued and are reflected in the June 30, 1999
balance sheet as Other Assets.

Other

   Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

   We may in the future seek to acquire untendered old notes in open market or
privately negotiated transactions, through subsequent exchange offers or
otherwise. We have no present plans to acquire any old notes that are not
tendered in the exchange offer or to file a registration statement to permit
resales of any untendered old notes.

                       CERTAIN INCOME TAX CONSIDERATIONS

Taxation of the Company

   We believe that a significant portion of our income will not be subject to
tax in Bermuda, which currently has no corporate income tax, or other countries
in which we conduct activities or in which our customers are located, including
the United States. However, this belief is based upon the anticipated nature
and conduct of our business, which may change, and upon our understanding of
our position under the tax laws of the various countries in which we have
assets or conduct activities, which position is subject to review and possible
challenge by taxing authorities and to possible changes in law (which may have
retroactive effect). The extent to which certain taxing jurisdictions may
require us to pay tax or to make payments in lieu of tax cannot be determined
in advance. In addition, our operations and payments due to us may be affected
by changes in taxation, including retroactive tax claims or assessments of
withholding on amounts payable to us or other taxes assessed at the source, in
excess of the taxation anticipated by us based on our business contacts and
practices and the current tax regimes. We cannot assure you that these factors
will not have a material adverse effect on our business, financial condition
and results of operations.

 Bermuda Tax Considerations

   Under current Bermuda law, we are not subject to tax on income or capital
gains. Furthermore, we have obtained from the Bermuda Minister of Finance under
the Exempted Undertakings Tax Protection Act 1966 (as amended), an undertaking
that, in the event that Bermuda enacts any legislation imposing tax computed on
profits or income or computed on any capital asset, gain or appreciation or any
tax in the nature of estate duty or inheritance tax, then the imposition of
such tax will not be applicable to us or to any of our operations, or our
shares, debentures or other obligations, until March 28, 2016. This undertaking
does not, however, apply to TBI or prevent the application of any tax or duty
to persons ordinarily resident in Bermuda or of any tax payable pursuant to the
Land Tax Act 1967 or otherwise payable in relation to land leased to us.

   As a condition to the grant of our international carrier license in Bermuda,
we were required to enter an agreement with the Bermuda Minister of Finance to
pay an ongoing license fee. Under the terms of the agreement, we are assessed a
fee equal to the greater of (i) six percent of our total revenue in Bermuda for
that period, and (ii) twenty percent of our profit in Bermuda for that period,
assessed on a historic cost depreciation basis and after allowing for
administrative and technical support costs not exceeding five percent of total
revenue in Bermuda.

   For purposes of this license fee agreement, total revenue is defined by
reference to the Cable & Wireless Act to mean total revenue from Bermuda
sources, net of local and foreign settlements. The limitation on administrative
and technical support costs is intended to restrict the allocation of such
costs in the form of management fees from parent companies. There is no limit
on the deductibility of these costs to the extent that they are incurred
directly.

 United States Federal Income Tax Considerations

   Our United States subsidiaries will be subject to United States federal
income tax on their worldwide income regardless of its source (subject to
reduction by allowable foreign tax credits), and distributions by such United
States subsidiaries to us or our foreign subsidiaries generally will be subject
to United States withholding tax, which generally is imposed at a rate of 30%
unless reduced by the provisions of an applicable income tax treaty. We and our
non-United States subsidiaries would be subject to United States federal income
tax at regular corporate rates (and to United States branch profits tax) on
income that is effectively connected with the conduct of a trade or business in
the United States, and would be required to file federal income tax returns
reflecting that income. We and our non-United States subsidiaries anticipate
that we will not be subject to United States federal income tax because neither
we nor any of our non-United States subsidiaries expect to derive any such
effectively connected income. However, we base this belief upon the anticipated
nature and conduct of our business and the business of our non-United States
subsidiaries, which may change. Moreover,

                                      131
<PAGE>

we cannot assure you that the Internal Revenue Service (the "IRS") will agree
with our positions in this regard.

 Tax Considerations in Other Jurisdictions

   Our subsidiaries that reside in other jurisdictions will be subject to tax
on some or all of their income. In addition, those jurisdictions may impose
withholding tax on distributions to such subsidiaries' parent. We anticipate
that we and our subsidiaries that do not reside in a particular jurisdiction
will not be subject to income taxation in that jurisdiction. Nonetheless, we
and our subsidiaries may be subject to withholding taxes imposed on payments
made to us and our subsidiaries by customers that reside in those countries.
Our belief as to this tax treatment is based upon the anticipated nature and
conduct of our business and that of our non-resident subsidiaries, which may
change. Moreover, we intend to conduct our operations to minimize the taxable
presence in any foreign jurisdiction outside Bermuda. However, we cannot assure
you that the taxing authorities in a jurisdiction will agree with our positions
in this regard.

Taxation of Noteholders

 Certain Bermuda Tax Considerations

   Under current Bermuda law, no income, withholding or other taxes or stamp or
other duties are imposed upon the issue, transfer or sale of the new notes or
on any payments thereunder. See "Taxation of the Company--Bermuda Tax
Considerations" for a description of the undertaking on taxes obtained by us
from the Bermuda Minister of Finance. There is no reciprocal tax treaty between
Bermuda and the United States regarding withholding taxes.

 Certain United States Federal Income Tax Considerations

   The following is a summary of certain United States federal income tax
considerations that apply to the exchange of the old notes for the new notes,
and ownership and disposition of the new notes by United States holders (as
defined below). Although the following summary does not describe all of the tax
considerations that may be relevant to you in light of your specific
circumstances, it describes the material United States federal income tax
consequences to a United States holder. We cannot assure you that the
conclusions set out below would be sustained by a court if challenged by the
IRS. We have not obtained, nor do we intend to obtain, a ruling from the IRS
with respect to the United States federal income tax consequences of this
Exchange Offer. This summary deals only with new notes that are held as capital
assets by United States holders that acquire new notes in exchange for old
notes that were purchased at their "issue price" and does not address federal
alternative minimum tax consequences or tax considerations applicable to United
States holders that may be subject to special tax rules, such as dealers or
traders in securities, financial institutions, insurance companies, tax-exempt
entities, United States holders that hold notes as a part of a straddle,
conversion transaction, constructive sale or other arrangement involving more
than one position, United States holders that have a principal place of
business or "tax home" outside the United States, United States holders whose
functional currency is not the United States dollar, and United States holders
that own notes through partnerships or other pass-through entities.

   The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), and regulations (the "Regulations"),
rulings and judicial decisions thereunder as of the date of this prospectus;
any such authority may be repealed, revoked or modified, perhaps with
retroactive effect, so as to result in United States federal income tax
consequences different from those discussed below. We urge each prospective
purchaser to consult its own tax advisor with respect to the tax consequences
of an investment in the notes, including the application to its particular
situation of the tax considerations discussed below, as well as the application
of state, local, foreign or other federal tax laws.

   You are a "United States holder" if you are a beneficial owner of the note
and you are (1) an individual who is a citizen or resident of the United
States, (2) a corporation or partnership created or organized in or

                                      132
<PAGE>

under the laws of the United States or any political subdivision thereof, (3)
an estate, the income of which is subject to United States federal income
taxation regardless of its source, or (4) a trust if the administration of the
trust is subject to the primary supervision of a court within the United States
and one or more United States persons (as described in section 7701(a)(30) of
the Code) have the authority to control all substantial decisions of the trust.
You are a "Non-United States holder" if you are a beneficial owner of the notes
and are not a United States holder.

 Taxation of United States Holders

   Exchange of New Notes for Old Notes: Pursuant to the Regulations, the
exchange of the new notes for old notes in the exchange offer, see "Exchange
Offer," should not constitute a significant modification of the terms of the
notes, and, accordingly, the exchange should be treated as a "non-event" for
federal income tax purposes. Therefore, the exchange should have no federal
income tax consequences to United States holders of notes. The holding period
of a new note will include the holding period of the old note for which it was
exchanged, and the basis of a new note will be the same as the basis of the old
note for which it was exchanged.

   Taxation of Interest: Interest on a new note will be taxable to a United
States holder as ordinary income at the time that such interest accrues or is
received, in accordance with the United States holder's regular method of
accounting for federal income tax purposes.

   Effect of Change in Control or Optional Redemption: Upon a Change of
Control, we are required to offer to redeem all notes then outstanding for a
price equal to 101% of the principal amount thereof plus accrued and unpaid
interest. Under the Regulations, such Change of Control redemption requirements
will not affect the yield or maturity date of the notes unless, based on all
the facts and circumstances as of the Issue Date, it was more likely than not
that a Change of Control giving rise to the redemption would occur. We will not
treat the Change of Control redemption provisions of the notes as affecting the
calculation of the yield to maturity of any note.

   We, at our option, may redeem part or all of the notes at the times and for
the amounts described in "Description of the New Notes--Optional Redemption"
herein. The Regulations provide that for purposes of calculating the yield to
maturity of a debt instrument, an issuer will be treated as exercising any
option if its exercise would lower the yield of the debt instrument. However, a
redemption of the notes at the optional redemption prices would increase the
effective yield of such notes as calculated from the date of issuance.
Therefore, in accordance with the Regulations, as of the date of issuance of
the notes, the optional redemption provisions will not be taken into account in
calculating the yield to maturity of the notes.

   Sale, Redemption or Retirement of New Notes: Upon the sale, redemption,
retirement at maturity or other taxable disposition of a new note, a United
States 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 the disposition (except to the extent such cash or property is
attributable to accrued but unpaid interest, which will be taxable as ordinary
income to the extent not previously taken into account) and the United States
holder's tax basis in the new note (generally the cost of the old note, see "--
Exchange of New Notes for Old Notes").

   Gain or loss recognized on the sale or other taxable disposition of a new
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 new note has been held for more
than one year (including the holding period of the old note, see "--Exchange of
New Notes for Old Notes"). In the case of a United States holder who is an
individual, long term capital gains generally are subject to tax at a maximum
rate of 20%. The deductibility of capital losses is subject to limitations.

 Taxation of Non-United States Holders

   For United States federal income tax purposes, a non-United States holder
generally will not be subject to tax or withholding on distributions made with
respect to, and gains realized from the disposition of, new notes

                                      133
<PAGE>

unless such distributions and gains are attributable to an office or fixed
place of business maintained by such non-United States holder in the United
States.

Information Reporting and Backup Withholding

   In general, information reporting requirements may apply to certain payments
of principal and interest on a new note, and to the payment of the proceeds of
the sale of a new note, to United States holders other than certain exempt
recipients (such as corporations). Backup withholding at a 31% rate will apply
to such payments if the United States holder fails to provide its taxpayer
identification number or certification of foreign or other exempt status,
provides an incorrect taxpayer identification number or fails to report in full
dividend and interest income.

   Any amounts withheld under the backup withholding rules will be allowed as a
credit against the United States holder's U.S. federal income tax liability and
may entitle such holder to a refund, provided that the required information is
furnished to the IRS.

                              PLAN OF DISTRIBUTION

   Based on interpretations by the staff of the Securities and Exchange
Commission in no action letters issued to third parties, we believe that you
may transfer new notes issued under the exchange offer in exchange for the old
notes if:

  . you acquire the new notes in the ordinary course of your business; and

  . you are not engaged in, and do not intend to engage in, and have no
    arrangement or understanding with any person to participate in, a
    distribution of such new notes.

   You may not participate in the exchange offer if you are:

  . our "affiliate" within the meaning of Rule 405 under the Securities Act;
    or

  . a broker-dealer that acquired old notes directly from us.

   Broker-dealers receiving new notes in the exchange offer will be subject to
a prospectus delivery requirement with respect to resales of the new notes.

   To date, the staff of the Securities and Exchange Commission has taken the
position that broker-dealers may fulfill their prospectus delivery requirements
with respect to transactions involving an exchange of securities such as this
exchange offer, other than a resale of an unsold allotment from the original
sale of the old notes, with the prospectus contained in the exchange offer
registration statement. Each broker-dealer that receives new notes for its own
account pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such new notes. This prospectus,
and any amendment or supplement to this prospectus, may be used by a broker-
dealer in connection with resales of new notes received in exchange for old
notes where such old notes were acquired 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 150 days after the
expiration date (subject to certain limitations set forth in the registration
rights agreement), we will make this prospectus, and any amendment or
supplement to this prospectus, available to any broker-dealer for use in
connection with any such resale. In addition, until such date all dealers
effecting transactions in the new notes may be required to deliver a
prospectus.

   If you wish to exchange new notes for your old notes in the exchange offer,
you will be required to make representations to us as described in "Exchange
Offer--Purpose and Effect of the Exchange Offer" and
"--Procedures for Tendering--Your Representations to Us" in this prospectus and
in the letter of transmittal. In addition, if you are a broker-dealer who
receives new notes for your own account in exchange for old notes
that were acquired by you as a result of market-making activities or other
trading activities, you will be required to acknowledge that you will deliver a
prospectus in connection with any resale by you of such new notes.

   We will not receive any proceeds from any sale of new notes by broker-
dealers. Broker-dealers who receive new notes for their own account in the
exchange offer may sell them 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 such
    methods of resale;

  . at market prices prevailing at the time of resale; and

  . at prices related to such prevailing market prices or negotiated prices.

   Any 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 any broker-dealer or the purchasers of any new notes. Any broker-dealer
that resells new notes it received for its own account in the exchange offer
and any broker or dealer that participates in a distribution of such new notes
may be deemed to be an "underwriter" within the meaning of the Securities Act
of 1933, and must deliver a prospectus meeting the requirements of

                                      135
<PAGE>

the Securities Act of 1933 in connection with any sale of the new notes. Any
profit on any resale of new notes and any commissions or concessions received
by any such persons may be deemed to be underwriting compensation under the
Securities Act of 1933. The letter of transmittal states that by acknowledging
that it will deliver and by delivering a prospectus, a broker-dealer will not
be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act of 1933.

                                      136

                                 LEGAL MATTERS

   The validity of the new notes will be passed upon for us by Vinson & Elkins
L.L.P., New York, New York (with respect to matters of United States law), and
Conyers Dill & Pearman, Hamilton, Bermuda (with respect to matters of Bermuda
law).

                             CHARTERED ACCOUNTANTS

   The financial statements for the fiscal years ended December 31, 1998 and
1997 and for the ten month period ended December 31, 1996, included in this
prospectus, have been so included in reliance on the report of
PricewaterhouseCoopers, Chartered Accountants, given on the authority of said
firm as experts in accounting and auditing.

                             AVAILABLE INFORMATION

   Members of the general public have the right to inspect the public documents
of a Bermuda company that are available at the office of the Registrar of
Companies in Bermuda. These documents include our Memorandum of Association
(including our objects) and any alteration to our Memorandum of Association.
Our shareholders have the additional right to inspect our bye-laws, minutes of
general meetings and audited financial statements, which must be presented at
the annual general meeting.

   The register of shareholders of a Bermuda company is also open to inspection
by shareholders without charge and to members of the general public upon the
payment of a fee. The register of shareholders is required to be open for
inspection for not less than two hours in any business day (subject to the
power to close the register for up to 30 days in each calendar year). A Bermuda
company is required to maintain its share register in Bermuda but may, subject
to the provisions of the Companies Act 1981 of Bermuda and related regulations
(the "Bermuda Act"), establish a branch register outside Bermuda. Our bye-laws
provide that, unless the board of directors otherwise determines, the share
register shall be open to inspection in the manner prescribed by the Bermuda
Act between 10:00 a.m. and 12:00 noon on every business day. A Bermuda company
is required to keep at its registered office a register of its directors and
officers that is open for inspection for not less than two hours in each day by
members of the public without charge. Bermuda law does not, however, provide a
general right for shareholders to inspect or obtain copies of any other
corporate records.

   The indenture governing the notes requires us to distribute to the holders
of the notes annual reports containing our financial statements audited by our
independent auditors and quarterly reports containing unaudited condensed
consolidated financial statements for the first three quarters of each fiscal
year.

   Upon consummation of the exchange offer, we will be subject to certain
reporting requirements of the Securities Exchange Act of 1934 and will file
reports, including reports on Form 10-K and 10-Q, and other information with
the Securities and Exchange Commission, so long as we are required or permitted
to do so. You can inspect and copy these reports and other information at the
Public Reference Room maintained by the Securities and Exchange Commission at:

                      GLOSSARY OF CERTAIN TECHNICAL TERMS

Amplifier

   A device used to boost the strength of an electronic or optical signal,
which is weakened (attenuated) as it passes through the transport network.
Amplifiers add gain to the signal by an amount equal to the loss in the
previous section of the network since the last amplification.

Backhaul Capacity

areas.

Bandwidth

   A measure of information-carrying capacity on a communications channel.

     1. The difference between the high and low frequencies of a transmission
  band, expressed in cycles per second (Hertz) or in wavelengths
  (nanometers). It is a measure of raw capacity without compression or coding
  of the information signal. A voice transmission requires about 3 KHz and a
  TV channel requires about 6 MHz.

     2. Transmission capacity is expressed in bits per second. For example
  megabits per second (Mbps) is a bit rate expressed in millions of bits per
  second while gigabits per second (Gbps) is a bit rate expressed in billions
  of bits per second.

   Narrowband:  Less than or equal to 64 kbps. Typical application: A single
                voice channel.

   Wideband:    Digital rates between 64 kpbs and 1.544 Mbps (DS-1) or 2.048
                Mbps (E-1s). Typical applications: Multiplexed voice channels,
                LANs, bulk files transfer, video conferencing and multimedia.

   Broadband:   Greater than 44.736 Mbps (DS-3s) or 34.368 Mbps (E-3). Typical
                applications: Broadcast quality video, Internet backbone.

</TABLE>

Broadband

   A transmission channel usually carrying a tremendous amount of information
at transmission speeds of 45 Mbps (45,000,000 bits per second) or greater. Some
facilities have transmission speeds in the billion of bits (gigabits per second
or Gbps).

   1. A communications channel with bandwidth sufficiently large to carry
voice, data and video on a single channel.

   2. Any voice communications channel having a bandwidth greater than a voice
grade channel.

  . A bandwidth of 45 Mbps can carry 672 voice connections (North American
    hierarchy)

  . Using compression equipment 2,688 telephone grade communication channels
    can be carried on one 45 Mbps broadband channel.

Digital

   Describes a method of storing, processing and transmitting information
through the use of distinct electronic or optic pulses representing the binary
digits 0 and 1. In communications they will modify a carrier at a selected
frequency. The precise signal transitions preclude any distortion such as
graininess or snow in the case of video transmission, or static or other
background distortion in the case of audio transmission.

Digital Transmission

   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 and switching technologies employ sequences of these
pulses to represent information as opposed to a continuously variable analog
signal. The precise digital numbers preclude any distortion such as graininess
or snow in the case of video transmission, or static or other background
distortion in the case of audio transmission.

                                AUDITORS' REPORT

                                                               February 22, 1999

To the Directors of
 GlobeNet Communications Group Limited

   We have audited the consolidated balance sheets of GlobeNet Communications
Group Limited (formerly TeleBermuda International Limited) as of December 31,
1998 and 1997 and the consolidated statements of operations, shareholders'
equity and cash flows for the years then ended and for the ten month period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

   In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of December 31,
1998 and 1997 and the results of its operations and its cash flows for the
years then ended and for the ten month period ended December 31, 1996 in
accordance with accounting principles generally accepted in the United States.

   On February 22, 1999 we reported separately to the Directors of GlobeNet
Communications Group Limited on consolidated financial statements for the years
ended December 31, 1998 and 1997 and the ten month period ended December 31,
1996 prepared in accordance with generally accepted accounting principles in
Bermuda.

       (in thousands of U.S. dollars, except share and per share amounts)

1 Formation and operations

   TeleBermuda International Limited ("TBI") was incorporated and registered on
January 6, 1995 as a local company pursuant to The Companies Act 1981
(Bermuda), for the purpose of establishing, providing, maintaining and
operating a public telecommunications service in Bermuda.

   GlobeNet Communications Group Limited (the "Company") was incorporated and
registered on June 25, 1998 as a Bermuda exempt company as part of a
reorganization of the TeleBermuda group of companies. Under the reorganization
TBI became a wholly-owned subsidiary of the Company and the issued shares of
TBI were exchanged on a one for one basis with substantially the same rights
and privileges as before.

   Following the reorganization, the Company incorporated certain subsidiaries.
GlobeNet Communications Limited ("GlobeNet"), a wholly-owned subsidiary of the
Company was incorporated on August 5, 1998 to be the operating company for
initiatives of the Company beyond the Bermuda market, GCG Holdings Ltda., 50%
owned by GlobeNet and 50% owned by TeleBermuda International (Canada) Limited,
a wholly-owned subsidiary of TBI, and GCG Services Ltda., 99% owned by GCG
Holdings Ltda. were incorporated in Brazil on December 10, 1998 to begin the
licensing process for fibre optic submarine cable landing and operating rights
in Brazil. As at December 31, 1998 these companies were inactive.

   On May 17, 1996, TeleBermuda International, L.L.C. was incorporated as a
limited liability company, under the laws of Delaware primarily for the purpose
of holding a landing license for the Company's BUS-1 cable system in the United
States and to own the associated landing plant. TBI has a 20% interest in
TeleBermuda International L.L.C. subject to a put and call agreement to
purchase the remaining 80% for nominal consideration, which effectively gives
TBI control of this entity. As a result, this entity has been consolidated in
these financial statements.

   TeleBermuda International (Canada) Limited was incorporated as a wholly-
owned subsidiary of TBI on September 16, 1996 for the purpose of providing
management services to the Company.

   On January 10, 1997, TBI was granted, for no consideration, its public
telecommunications service license in Bermuda under the provisions of the
Telecommunications Act, 1986 and the Public Telecommunication Service (Licence)
Regulations, 1988 for a five-year term.

   In addition, TBI has an interconnection agreement with the Bermuda Telephone
Company ("BTC"), the domestic carrier, that enables the Company to directly
connect its operating facility with BTC in order to terminate traffic in and
receive traffic from Bermuda for as long as each party has their public
telecommunications service license in Bermuda. No consideration was paid by the
Company in relation to this agreement.

2 Summary of significant accounting policies

   These consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States ("U.S. GAAP").
The following is a summary of the significant accounting policies followed in
the preparation of these consolidated financial statements.

 Principles of consolidation

   The consolidated financial statements include the accounts of the Company
and all of its subsidiary companies. Intercompany accounts and transactions
have been eliminated on consolidation.

                                      F-7

       (in thousands of U.S. dollars, except share and per share amounts)


 Use of significant accounting estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting periods. Actual results could significantly differ from
those estimates.

 Revenue and cost recognition

   The Company provides telecommunication services and the granting or leasing
of indefeasible rights of use ("IRU") interests in its telecommunications
infrastructure.

   The Company records as revenue the amount of telecommunications services
rendered, as measured primarily by the minutes of traffic processed, after
deducting an estimate of the traffic for which revenue will not be collected.
Historical deductions have not been material. Service discounts and incentives
are accounted for as a reduction of revenue when granted, or where provided in
relation to a service contract, rateably over the contract period.

   Revenue from the granting of an IRU in its telecommunications infrastructure
to third parties is recognized at the effective date of the contract provided
certain conditions are met. The Company considers the risks and rewards of
ownership to have transferred when the granting price is fixed on a non-
refundable basis, customers are responsible for their pro-rata share of the
costs for operating, maintaining and restoring the systems and the granting
term is for the operational life of the infrastructure sold pursuant to the
IRU.

   Revenues from private line services are recognized as earned.

 Cost

   Carrier charges are comprised primarily of local access charges and
international termination costs. These costs are recognized based on traffic
volume.

 Deferred revenue

   Revenue from the lease of capacity in telecommunications infrastructure to
third party carriers is deferred and recognized over the term of the lease on a
straight-line basis. Revenue from the sale of prepaid calling cards is
recognized as the services are provided.

 Capital assets

   Capital assets are recorded at cost less accumulated amortization.
Amortization commences when an asset is put into service, and is calculated in
a systematic manner based on the expected useful lives of the assets as
follows:
<TABLE>
<CAPTION>
   Asset category                        Basis               Rate
   --------------                        -----               ----
   <S>                                   <C>                 <C>
   Fibre optic submarine cable.......... straight-line       25 years
   Network and telecommunications
    equipment........................... straight-line       10 years
   Leasehold improvements............... straight-line       term of the lease
   Computer equipment................... straight-line       3 years
   Furniture and office equipment....... diminishing balance 20% per annum
   Software............................. straight-line       5 years
</TABLE>

 Deferred financing costs

   Deferred financing costs represent debt issuance costs, which are amortized
over the estimated term of the related debt.

       (in thousands of U.S. dollars, except share and per share amounts)

 Investment

   The Company's investment in Rocom TBI Limited is accounted for using the
equity method.

 Foreign currency translation

   Monetary assets and liabilities denominated in foreign currencies are
translated into U.S. dollars at exchange rates prevailing at the balance sheet
date. Revenues and expenses are translated into U.S. dollars at the average
rates of exchange prevailing at the dates of the respective transactions.
Transactions are translated into U.S. dollars at the exchange rates in effect
at the time the transactions occur. Exchange gains and losses arising on
translation are included in the operating results for the year.

   The assets and liabilities of the non-Bermudian subsidiaries, which are
considered to be self-sustaining operations, are translated at the exchange
rate in effect at the balance sheet date. Revenues and expenses are translated
at average exchange rates prevailing during the year.

 Financial instruments

   The fair value of financial assets and liabilities represents the amount at
which these instruments could be exchanged in a current transaction between
willing parties. The carrying values of financial assets and liabilities as at
December 31, 1998 approximate their fair values.

 Income taxes

   Under current Bermuda laws, the Company is not required to pay any taxes in
Bermuda on either income or capital gains. The Company has received an
undertaking from the Minister of Finance in Bermuda, pursuant to the Exempted
Undertakings Tax Protection Act 1966, which exempts the Company from any such
tax until March 28, 2016. Subsidiaries in other jurisdictions may be subject to
local taxes.

 Recent accounting pronouncements

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities". This statement which is effective for fiscal years beginning after
December 15, 1998, requires costs incurred to open a new facility, introduce a
new product, commence a new operation or other similar activities to be
expensed as incurred. Management has not determined the impact of this
statement on its financial position, results of operations and cash flows.

3 Change in reporting currency

   Effective January 1, 1998, the Company has adopted the U.S. dollar as its
reporting currency. Its previous currency was the Bermuda dollar. Since the
Bermuda dollar is pegged to the U.S. dollar on a one-to-one basis there are no
differences that arise as a result of this change in reporting currency.

4 Due from related party

   On August 26, 1998, TBI loaned $1,292 (CAD$2,000) to the Chairman and Chief
Executive Officer of the Company. The Chairman and Chief Executive Officer used
the proceeds of the loan to invest in a joint venture with a third party
carrier. The loan to the Chairman and Chief Executive Officer, and his
participation in the joint venture, was conditional on the third party carrier
granting an option in favour of TBI to acquire an equity interest in the third
party carrier's Canadian operations. The option was exercisable until November
30, 1998 for a 20% equity interest in the Canadian operations for an exercise
price of CAD$11,525. As a result of the Company's later decision to pursue the
development of the Atlantica-1 Network, TBI elected not to exercise the option.
Subsequent to year-end, the loan to the Chairman and Chief Executive Officer
and all interest thereon was repaid in full.

     a) The GeoReach Partnership ("GeoReach") was formed on October 6, 1995
  for the purpose of obtaining and exploiting an international carrier
  licence in Canada. The original partners were the Chairman and Chief
  Executive Officer of the Company and a Director of the Company. During the
  year, GeoReach was dissolved, the assets were transferred to GeoReach
  Telecommunications Inc. ("GeoReach Inc.") and the Company's 5% interest in
  GeoReach Partnership was increased to 100% when the additional 95% was
  acquired from the Chairman and Chief Executive Officer and a Director of
  the Company for $124. Subsequently, due to a change in business strategy,
  this investment was written off.

     a) On July 28, 1997, the Company entered into a five-year term loan
  agreement with a bank for up to $25,000 to finance capital expenditures.
  During the year, the available credit on the term facility was reduced to
  $21,990. As at December 31, 1998 the unused facility was $nil (1997--
  $8,260). The loan bore interest at the London Interbank Offered Rate
  ("Libor") plus 2.25% for the period to July 28, 1998, and

  subsequently at interest rates between Libor plus 1.75% and Libor plus
  2.25% subject to reduction upon the Company meeting certain cashflow
  criteria. At the option of the Company, the interest rate may be fixed or
  converted to a floating rate based on the U.S. prime rate. During the year,
  the average rate of interest incurred on this loan was 7.8% (1997--8.0%).

     b) On July 28, 1997, the Company entered into a five year revolving
  operating credit facility with a bank for up to $5,000 to finance the
  Company's general working capital requirements. The facility bears interest
  on the same terms as the term loan. As at December 31, 1998 the unused
  facility was $3,313 (1997--$5,000). Any further draws on this facility will
  require term lender approval. The average rate of interest incurred on this
  loan in 1998 was 7.7%.

   The principal repayments in respect of the term loan and operating line are
as follows:

     c) On July 28, 1997, the Company entered into a subordinated debenture
  agreement with a financial institution and a vendor for up to $13,000 to
  fund capital expenditures. As at December 31, 1998, the principal
  outstanding under this loan was $13,000 (1997--$13,000), and is due for
  repayment on July 28, 2002. The debenture bears interest at a rate of Libor
  plus 5%. Interest accrues for the first two years and is payable on a
  quarterly basis commencing July 28, 1999. The average rate of interest
  incurred on the debenture in 1998 was 10.72% (1997--10.68%). Included in
  accounts payable is accrued interest of $1,967 (1997--$455).

       As part of the subordinated debentures agreement, the Company issued
  up to 1,529,412 common share purchase warrants to the debenture holders.
  The warrants are exercisable at prices between $8.50 and $9.25 per common
  share. The Company may repurchase all outstanding warrants subsequent to
  July 28, 1998, subject to certain covenants and conditions. The warrants
  expire if unexercised on July 28, 2002, in which case, the Company is
  required to make a non-exercise payment of up to $5,392, representing
  additional contingent interest at 7% per annum on the gross exercise price
  for the unexercised warrants from the date of issue to the date of expiry.
  The warrants have anti-dilution protection rights whereby the exercise
  price of the warrants and the number of common shares issuable by the
  Company on exercise of the warrants will be increased or decreased in
  certain events, including certain reorganizations and the issuance by the
  Company of equity shares at a price which is less than the warrant exercise
  price or less than the market price of the Company's common shares. The
  Company will accrue the additional contingent interest at 7% per annum over
  the five year term of the debt. Management estimates that any additional
  value attributable to the equity component of the warrants is
  insignificant.

   All assets of the Company have been pledged as collateral against the term
loan, the operating credit facility and the subordinated debentures.

10 Granting of indefeasible rights of use to and leasing of the fibre optic
submarine cable

   a) The Company has granted indefeasible rights of use ("IRU's") in its fibre
optic submarine cable to certain third party carriers for a period of 25 years
for $1,521. The costs recognized with the granting of the IRU's are calculated
on a pro-rata basis of total capacity granted in relation to the total cost of
the activated fibre optic submarine cable.

   b) The Company has signed an agreement to lease capacity in its fibre optic
submarine cable to a third party. The term of the lease is for the greater of
25 years or the operational life of the fibre optic submarine cable. The
operational life can be no less than 10 years, otherwise the Company must
provide a refund to the third party, on a pro-rata basis for each year short of
the 10 year period. During the lease term, the Company is responsible for the
maintenance and operating costs associated with the fibre optic submarine cable
for the first four years and thereafter the lessee is responsible for payment
of a monthly charge for operating and maintenance costs. The lease also
requires that the Company have full restoration capacity as of January 1, 2000,
otherwise without such capacity, the lease may be terminated and a refund of
$4,400 would be required to be made by the Company. The total consideration for
this lease was $8,000, which was reduced by $135 as a result of an offset for a
receivable by the third party owing to the Company. During 1998, $2,865 was
received. $4,000 is due September 24, 1999 and $1,000 is due on September 24,
2000. The Company has recognized revenue of $263, related to this lease.

   This agreement also entitles the third party to enter into a second lease of
capacity in the fibre optic submarine cable commencing on the third anniversary
of the September 24, 1998 activation date of the first circuit, expiring at the
same time as the first lease. The consideration for the second lease will be
$4,000 payable upon activation of the second circuit. Prior to signing the
second lease, the third party may elect not to proceed with the second lease at
a penalty of $250 payable to the Company.

11 Minority interest and equity accounted for investment

   TeleBermuda International (U.K.) Limited ("TBI-UK") was incorporated on June
19, 1996 for the purpose of acquiring and exploiting a license to provide
telecommunications services in the United Kingdom. On November 27, 1997, TBI-UK
changed its name to Rocom TBI Limited ("Rocom TBI") and commenced active
operations. During the year, Rocom TBI was used to establish a corporate joint
venture in the United Kingdom for the purpose of securing a gateway to Europe
and the European market. On December 16, 1998 the Company sold its 50% interest
in Rocom TBI to its joint venture partner.

12 Share capital

      All issued and outstanding common shares are fully paid.

  option, 32,500 with an exercise price of $1.00 per option and 196,989 with
  an exercise price of $3.00 per option) reflected at their fair value.

     ii) In May 1996, the Company advised the holders of the shares that were
  uncalled at February 29, 1996 that it intended to make a call in respect of
  all monies unpaid on these shares.

     iii) In October 1996, the Company completed an initial public offering
  on the Bermuda Stock Exchange and private placements in the United States,
  Canada and the United Kingdom. Pursuant to these offerings, the Company
  issued 2,118,000 shares for proceeds of $16,838 net of expenses of the
  offering of $1,165.

     iv) On July 28, 1997, 50,000 options were granted to non-employees.
  Those options were granted with respect to a financing and have been
  accounted for at fair value as deferred financing cost, amortized over the
  five year term of the loan agreement.

     v) On October 3, 1997 the members passed a bylaw to convert 100 of the
  authorized common shares into 100 Class A restricted voting shares. Class A
  shareholder approval is required for certain corporate matters. On that
  date, 80 Class A shares were issued to the subordinated debenture holders,
  and 20 shares were issued to a director of the Company for cash
  consideration of $1.50 per share.

  The Company is entitled to repurchase the Class A shares for cancellation,
  at a price of $1.50 per share. This can occur in the event of the
  repurchase or expiry of the debenture holders warrants, or in certain
  circumstances involving the dilution of the debenture holders' equity
  interest taken on a fully diluted basis.

Under the terms of the Company's credit agreement the Company's payment of
dividends is subject to restrictions related to the repayment terms of the term
loan, operating credit facility and subordinated debt.

   The weighted average exercise price of the options outstanding and the
options exercisable at December 31, 1998 are $6.41 and $4.49, respectively. The
weighted average fair value of the options granted in 1998 and 1997 are $0.44
and $1.97, respectively.

   The Company applies APB Opinion 25 ("Accounting for Stock Issued to
Employees") in accounting for its stock option plan (except for options granted
to employees of service providers), and, accordingly, does not recognize
compensation cost at the time options are granted unless the exercise price is
less than the market price of the stock on the date of issue. Had the Company
elected to recognize compensation cost based on the fair value of the options
granted at the grant date as prescribed by SFAS 123, the pro forma effects to
reported net loss for the period and basic and fully diluted loss per common
share, would be as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

      (in thousands of U.S. dollars, except share and per share amounts)

   The fair value of each option grant has been estimated using the Black-
Scholes option pricing model, using a volatility assumption of 20% (1997--20%;
1996--20%), expected life of 7 years (1997--7 years; 1996--7 years), a
dividend rate of nil (1997--nil; 1996--nil) and a risk-free interest rate of
5.28% (1997--6.33%; 1996--6.60%).

   The above pro forma effects on the net loss for the period may not be
representative of the effects on the net loss for the period for future
periods as option grants typically vest over several years and additional
options are generally granted each year.

14 Basic and fully diluted loss per common share

   The basic loss per common share is calculated using the weighted average
number of common shares outstanding of 3,515,927 (1997--3,492,915; 1996--
1,722,916). The weighted average number of common shares on a fully diluted
basis is calculated on the same basis as the basic weighted average number of
shares as the Company is in a loss position and the effects of possible
conversion would be anti-dilutive.

15 General and administrative expenses

  a) Director's service contract

   In September 1997, the Company entered into a service agreement with First
Bermuda Securities Ltd., of which a Director of the Company is the CEO. Under
this agreement, First Bermuda Securities Ltd. provides the Company with
various financial and business advisory services. Payments made to First
Bermuda Securities in 1998 were $125 (1997--$145; 1996--$nil).

  b) Rent expense

   Included in general and administrative expenses is rent expense of $342
(1997--$242; 1996--$127).

  c) Bad debt expense

   Included in general and administrative expenses is bad debt expense of $114
(1997-$91; 1996-$ nil).

  d) Compensation expense

   Included in general and administrative expenses is compensation expense of
$nil (1997-$nil; 1996-$1,845).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

       (in thousands of U.S. dollars, except share and per share amounts)

   In the normal course of business, the Company has also entered into a number
of contracts under which it is committed to the purchase and supply of
telecommunication services at fixed prices. It is not anticipated that losses
will be incurred on these contracts.

18 Contingencies

   The Company is a defendant or interested party (note 21(a)) in various
lawsuits which have arisen in the ordinary course of business. At the present
time, the outcome of these cases is not determinable and the estimate of the
range of the potential loss is $nil to $32. No provision has been made with
respect to any of these claims in these financial statements.

   The Company is contingently liable in respect of an irrevocable stand-by
letter of credit issued by a bank on its behalf in the amount of $55 (1997--
$75).

19 Segmented information

   The Company operates predominantly in the telecommunications sector and
substantially all of the Company's business activity and services were
conducted in Bermuda during 1998, 1997 and 1996.

20 Uncertainty due to 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 an entity's ability to conduct normal business operations.
It is not possible to be certain that all aspects of the Year 2000 Issue
affecting the entity, including those related to the efforts of customers,
suppliers, or other third parties, will be fully resolved.

21 Subsequent events

   a) On January 8, 1999, the Bermuda Telephone Company ("BTC"), the domestic
carrier, filed a notice of appeal with the Supreme Court of Bermuda challenging
the Minister of Telecommunications' December 31, 1998 decision to mandate
certain reductions in the local access charges paid by international carriers,
including the Company, to domestic carriers commencing January 1, 1999. A
favourable ruling for BTC could nullify the existing access charge reduction
and could have retroactive effect commencing from January 1, 1999. The outcome
of this proceeding is currently not determinable.

   b) On February 18, 1999 the Company signed a letter of intent to award
Alcatel Submarine Networks ("Alcatel") a supply contract to construct a fibre
optic submarine cable called Atlantica-1 between Hollywood (Fl, USA), Punto
Fijo (Venezuela), Fortaleza (Brazil), St. David's (Bermuda) and Tuckerton (NJ,
USA) for a contract price of $510,485, which amount is subject to amendment by
the mutual agreement of the parties. This letter of intent may be cancelled at
any time prior to June 15, 1999 with the Company's liability being limited to
the actual costs and expenditures authorized by the letter of intent up to a
maximum of $4,000. If a definitive supply contract is cancelled between the
parties, payment of the costs and expenditures incurred by Alcatel become
payable by the Company on June 15, 1999. The Company will render payment of
these costs from

       (in thousands of U.S. dollars, except share and per share amounts)

either financing proceeds or the issuance of a note to Alcatel which shall be
subordinate to the existing financing facilities. As specified in the letter of
intent, the supply contract is anticipated to be signed by April 30, 1999,
which was subsequently extended to May 30, 1999, and construction of the cable
system to be completed by December 30, 2000. The Company is currently pursuing
financing initiatives to fund this commitment.

   In February 1999 the Company reached an agreement in principle with one of
its debenture holders to secure an additional $500 to fund costs for planning
and financing initiatives on the Atlantica-1 project. The terms and conditions
of this additional funding are essentially the same as those for the Company's
existing subordinated debt and warrants.

   c) Unaudited--Effective June 15, 1999, the authorized common shares of the
Company were increased by 10,499,900 to an aggregate total of 17,499,800 common
shares. In addition, the Company's bye-laws authorized the creation of 100
Class B shares. On July 12, 1999, the authorized common shares and Class B
shares of the Company were increased by 6,500,200 and 1,900, respectively.

   d) Unaudited--On July 14, 1999 the Company secured financing totalling
$970,580 for the development and construction of the Atlantica-1 fibre optic
submarine cable system linking North America, Bermuda and South America. The
financing is comprised of the following components:

   i)   A private placement equity offering of shares issued at $20.40 per share
        (par value $1.50) for aggregate proceeds of $270,580. The Company
        subsequently used $30,600 of these proceeds to redeem 1,500,000
        outstanding common shares at an aggregate price of $20.40 per common
        share from existing shareholders.

   ii)  The issuance of debt in the principal amount of $300,000 in the form of
        13% senior notes maturing July 15, 2007. Interest on these notes accrues
        at a rate of 13% per annum, payable semi-annually in arrears on each
        January 15 and July 15 commencing January 15, 2000. The notes
        effectively rank behind all of the collateralized obligations of the
        Company to the extent of the value of the assets collateralizing these
        obligations.

   iii) A bank credit facility ("Credit Facility") of up to $400,000, that
        consists of various term facilities totalling $390,000 and a $10,000
        revolving credit facility. All loans under the Credit Facility
        mature on June 30, 2005 except for one of the term facilities of
        $100,000 which matures on September 30, 2005. The interest rates on
        the loans under the Credit Facility range from Libor plus 3.5% to
        Libor plus 4.0% and availability of funds under the Credit Facility
        is subject to certain terms and conditions. Substantially all of the
        assets of GlobeNet Communications Holdings Ltd. and of its present
        and future direct and indirect subsidiaries have been pledged as
        collateral for the Credit Facility. In addition, Alcatel has
        provided an initial guarantee subject to certain conditions and
        adjustments of up to $100,000 for one of the term facilities.

     The structure, terms and pricing of the Credit Facility are subject
     to change at the discretion of the bank that is acting as arranger up
     until October 15, 1999.

   In addition, on July 14, 1999, $21,408 of the proceeds from the total
   financing amount of $970,580, were used to pay the existing term loan,
   operating credit facility and certain accrued interest on the
   subordinated debentures. As well, all of the remaining obligations to the
   subordinated debentureholders were retired when the subordinated
   debentureholders elected to exercise their warrants and convert the
   principal and remaining accrued interest on their subordinated debt into
   1,635,286 common shares. The shares issued in respect of the subordinated
   debentures and accrued contingent interest obligation were included in
   share capital and additional paid-in capital at their carrying amounts.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                For the six months ended June 30, 1999 and 1998

       (in thousands of U.S. dollars, except share and per share amounts)

1 Formation and operations


   GlobeNet Communications Group Limited (the "Company") was incorporated and
registered on June 25, 1998 as a Bermuda exempt company as part of a
reorganization of the TeleBermuda International Limited group of companies
("TBI"). Under the reorganization, TBI, which was incorporated on January 6,
1995, became a wholly-owned subsidiary of the Company and the issued shares of
TBI were exchanged on a one-for-one basis with substantially the same rights
and privileges.

   The Company, through its subsidiaries, provides, maintains and operates a
public telecommunications service in Bermuda facilitated by its ownership of
its BUS-1 cable system between Bermuda and the United States. On January 10,
1997, TBI was granted, for no consideration, its public telecommunications
service licence in Bermuda under the provisions of the Telecommunications Act,
1986 and the Public Telecommunication Service (Licence) Regulations, 1988 for a
five-year term.

   In addition, TBI has an interconnection agreement with the Bermuda Telephone
Company ("BTC"), the domestic carrier, that enables the Company to directly
connect its operating facility with BTC in order to terminate traffic in and
receive traffic from Bermuda for as long as each party has its public
telecommunications service license in Bermuda. No consideration was paid by the
Company in relation to this agreement.

   On June 16, 1999, the Company entered into a construction contract, subject
to certain terms and conditions, including the securing of financing to expand
its operations by building a fibre optic submarine cable system called
Atlantica-1 linking Bermuda, North and South America. Such financing was
secured on July 14, 1999 (note 7).

2 Interim consolidated financial statements

   The unaudited consolidated balance sheets as at June 30, 1999, June 30, 1998
and December 31, 1998 and the unaudited consolidated statements of operations
and deficit and statements of cash flows for the six-month periods then ended,
in the opinion of management, have been prepared on the same basis as the
audited consolidated financial statements and include all adjustments necessary
for the fair statement of the results of the interim periods. All adjustments
reflected in the consolidated financial statements are of a normal recurring
nature. The data disclosed in the notes to the consolidated financial
statements for these periods are also unaudited. Results for the six-month
periods ended June 30, 1999 and 1998 are not necessarily indicative of the
results to be expected for the full year.

 Recent accounting pronouncements

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities". This statement which is effective for fiscal years beginning after
December 15, 1998, requires costs incurred to open a new facility, introduce a
new product, commence a new operation or other similar activities to be
expensed as incurred. The Company has adopted the SOP and it had no impact on
the statement of its financial position, results of operations or cash flows.

       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                For the six months ended June 30, 1999 and 1998

       (in thousands of U.S. dollars, except share and per share amounts)

3 Share capital

   Effective June 15, 1999, the authorized common shares of the Company were
increased by 10,499,900 to an aggregate total of 17,499,800 common shares. In
addition, the Company bye-laws authorized the creation of 100 Class B shares.
On July 12, 1999, the authorized common shares and Class B shares of the
Company were increased by 6,500,200 and 1,900, respectively.

4 Common share options

   The Company awards options to employees, officers and directors of the
Company and employees of service providers under the terms of the 1997 and 1998
Share Option and Incentive Plans. In addition, the Board can grant options
outside of these plans under separate stock option agreements.

   On April 12, 1999, the Company granted 540,000 options at an exercise price
of $9.00 with a ten-year term to certain officers and directors. These options
vest in three separate tranches based upon the Company meeting certain
milestones related to the Atlantica-1 project. The first vesting milestone on
515,000 of these options occurred on July 14, 1999 when total financing was
secured (note 7). The difference between the exercise price and the market
value of the shares at the time of vesting will be reflected as compensation
expense.

   At June 30, 1999 there were 1,347,489 (1998--551,489) outstanding common
share purchase options at a weighted average exercise price of $7.45 (1998--
$5.20). During the six month period ended June 30, 1999, 4,000 (1998--5,000)
options were forfeited at a weighted average exercise price of $8.50 (1998--
$8.00). These options expire on various dates from 2001 to 2009 and generally
vest over a three-year period.

5 Commitments

   On June 4, 1999, the Company signed a revised letter of intent to award
Alcatel Submarine Networks ("Alcatel") a supply contract to construct a fibre
optic submarine cable system called Atlantica-1 between Miami (Fl, USA), Camuri
(Venezuela), Fortalez (Brazil), St David's (Bermuda) and Tuckerton (NJ, USA)
for a total contract price of $620,861, (of which $6,000 has been recorded at
June 30, 1999), which amount is subject to amendment by the mutual agreement of
the parties.

   Future payments are based upon a specified billing schedule and are due when
the corresponding project milestone has been achieved and engineer acceptance
has been provided. Contract costs will be capitalized and reflected as
construction in progress based on the project's percentage of completion as
determined by engineering estimates.

   The future minimum payments, beyond the $6,000 that has been recorded in
accrued liabilities as at June 30, 1999, required in the next two years as a
result of this contract are as follows:

   As disclosed in note 7, financing was secured on July 14, 1999 and as a
result, the Company made its initial payment under the billing schedule of
$62,086.

       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
                For the six months ended June 30, 1999 and 1998

       (in thousands of U.S. dollars, except share and per share amounts)

6  Contingencies

   On January 8, 1999, the Bermuda Telephone Company ("BTC"), the Bermuda
domestic carrier, filed a notice of appeal with the Supreme Court of Bermuda
challenging the Minister of Telecommunications' ("Minister") December 31, 1998
decision to mandate certain reductions in the local access charges paid by
international carriers, including the Company, to domestic carriers commencing
January 1, 1999. The appeal was settled on March 23, 1999 without any impact to
the mandated reductions. The proceedings had been adjourned until June 23,
1999, at which time a hearing was scheduled for July 19, 1999 for purposes of
preserving BTC's rights in the event of a third party appeal. On July 19, 1999,
BTC abandoned the appeal.

7 Subsequent events

   On July 14, 1999 the Company secured financing totalling $970,580 for the
development and construction of the Atlantica-1 fibre optic submarine cable
system linking North America, Bermuda and South America. The financing is
comprised of the following components:

  (i)   A private placement equity offering of shares issued at $20.40 per share
        (par value $1.50) for aggregate proceeds of $270,580. The Company
        subsequently used $30,600 of these proceeds to redeem 1,500,000
        outstanding common shares at an aggregate price of $20.40 per common
        share from existing shareholders.

  (ii)  The issuance of debt in the principal amount of $300,000 in the form of
        13% senior notes maturing July 15, 2007. Interest on these notes accrues
        at a rate of 13% per annum, payable semi-annually in arrears on each
        January 15 and July 15 commencing January 15, 2000. The notes
        effectively rank behind all of the collateralized obligations of the
        Company to the extent of the value of the assets collateralizing these
        obligations.

  (iii) A bank credit facility ("Credit Facility") of up to $400,000, that
        consists of various term facilities totalling $390,000 and a $10,000
        revolving credit facility. All loans under the Credit Facility mature
        on June 30, 2005 except for one of the term facilities of $100,000
        which matures on September 30, 2005. The interest rates on the loans
        under the Credit Facility range from Libor plus 3.5% to Libor plus
        4.0% and availability of funds under the Credit Facility is subject
        to certain terms and conditions. Substantially all of the assets of
        GlobeNet Communications Holdings Ltd. and of its present and future
        direct and indirect subsidiaries have been pledged as collateral for
        the Credit Facility. In addition, Alcatel has provided an initial
        guarantee subject to certain conditions and adjustments of up to
        $100,000 for one of the term facilities.

    The structure, terms and pricing of the Credit Facility are subject to
    change at the discretion of the bank that is acting as arranger up
    until October 15, 1999.

   In addition, on July 14, 1999, $21,408 of the proceeds from the total
financing amount of $970,580, were used to pay the existing term loan,
operating credit facility and certain accrued interest on the subordinated
debentures. As well, all of the remaining obligations to the subordinated
debentureholders were retired when the subordinated debentureholders elected to
exercise their warrants and convert the principal and remaining accrued
interest on their subordinated debt into 1,635,286 common shares. The shares
issued in respect of the subordinated debentures and accrued contingent
interest obligation were included in share capital and additional paid-in
capital at their carrying amounts.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers

 Indemnification Agreements with Directors

   We have entered into indemnity agreements with each of our directors (other
than Mr. DeMartino, with whom we expect to enter into such an agreement in the
near future). Pursuant to the director indemnity agreements, we have agreed to
indemnify and save harmless each director, his/her heirs and legal
representatives, to the fullest extent permitted by law, against all costs,
charges, liability, damages, and expenses, including an amount paid to settle
an action or to satisfy a judgment, reasonably incurred by him/her in respect
of any civil, criminal or administrative action or proceeding to which he/she
is made a party by reason of, or in any connection with him/her, being or
having been a director if (1) the director acted in his/her capacity as a
director and (2) in the case of a criminal or administrative action or
proceeding that is enforced by a monetary penalty, the director had reasonable
grounds for believing that his/her conduct was lawful. Directors are required
to obtain our consent to any settlement of any civil, criminal or
administrative action or proceeding.

 Indemnification Agreements with Officers

   We have entered into indemnity agreements with Michael Kedar, James
Fitzgerald, Laurent Duplantie, Scott Socol, Lin Gentemann and Greg Belbeck. We
expect to enter into similar indemnity agreements with Messrs. DeMartino, Blust
and Weisbrot in the near future. Pursuant to the indemnification agreements, we
have agreed, to the fullest extent permitted by our bye-laws and applicable
law, to indemnify each indemnitee against all expenses actually and reasonably
incurred, judgments, penalties, fines and amounts paid in settlement by such
indemnitee if he/she is, or is threatened to be made, a party to any
threatened, pending, or completed action, suit, arbitration, alternate dispute
resolution mechanism, investigation, administrative hearing or any other
proceeding as a result of his/her status as an employee or officer of the
Company (1) if, in a proceeding other than a proceeding by or in the right of
the Company, he/she acted in good faith and in a manner reasonably believed to
be in our best interests and, with respect to a criminal proceeding, if he/she
had no reasonable cause to believe his/her conduct was unlawful and (2) if, in
a proceeding brought by or in the right of the Company to procure a judgment in
its favor, to the extent such indemnitee is successful, on the merits or
otherwise, provided that if the indemnitee is only partially successful in such
proceeding, we agree to indemnify him/her for such expenses actually and
reasonably incurred by him/her or on his/her behalf in connection with each
successfully resolved claim, issue or matter.

 Bye-laws

   Our bye-laws provide that, subject to the Companies Act 1981 of Bermuda,
every director, officer and member of a committee constituted in accordance
with our bye-laws is indemnified by us against (1) all civil liabilities, loss,
damage, charge or expense incurred or suffered by him as a director, officer or
committee member while exercising his powers and discharging his duties under
the Companies Act 1981 of Bermuda and our bye-laws and (2) all liabilities
incurred by him as a director, officer or committee member in defending any
proceedings, whether civil or criminal, in which judgment is given in his favor
or in which he is acquitted, or in connection with any application under the
Companies Act 1981 of Bermuda in which relief from liability is granted to him
by the court. The indemnity extends to any person acting as a director, officer
or committee member in the reasonable belief that he has been so appointed or
elected notwithstanding any defect in such appointment or election provided,
however, that the indemnity does not extend to any matter which would render it
void pursuant to the Bermuda Act.

   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 of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

     2.1  The Guaranty.  Except as expressly set forth herein, the Guarantor
hereby absolutely, irrevocably and unconditionally (i) guarantees to Agent
Company's prompt payment in full when due, pursuant to the terms of the Credit
Agreement, whether at stated maturity, by required prepayment, declaration,
acceleration, demand or otherwise, of the Guaranteed Draw Amount (including all
such amounts which would become due but for (x) the operation of any provision
of any law that prevents the commencement or continuation of any act or actions
against a debtor such as the automatic stay under Section 362(a) of the United
States Bankruptcy Code, 11 U.S.C. (S)362(a), and (y) the operation of any
provision of any law that disallows a claim against a debtor because such claim
is unsecured, unmatured or unenforceable such as Sections 502(b) and 506(b) of
the United States Bankruptcy Code, 11 U.S.C. (S)502(b) and (S)506(b)),
(collectively, the "Guaranteed Obligations") and (ii) indemnifies and holds
                    ----------------------
harmless each Lender Party for any and all costs and expenses (including
reasonable attorney's fees and expenses) incurred by such Lender Party in
enforcing any rights under this Guaranty. This Guaranty constitutes a guaranty
of payment when due and not of collection. The Guaranteed Obligations shall
conclusively be deemed to have been created in reliance upon this Guaranty.

     2.2  Acceleration of Guaranty.  The Guarantor agrees that, in the event of
the dissolution or insolvency of the Company or the Guarantor, or the inability
or failure of the Company or the Guarantor to pay debts as they become due, or
an assignment by the Company or the Guarantor for the benefit of creditors, or
the commencement of any case or proceeding in respect of the Company or the
Guarantor under any bankruptcy, insolvency or similar laws, and if such event
shall occur at a time when any of the Guaranteed Obligations may not then be due
and payable, the Guarantor will pay to the Agent, for the benefit of the Lender
Parties, forthwith the full amount which would be payable hereunder by the
Guarantor if all such Guaranteed Obligations were then due and payable.

     2.3  Termination of Guaranty.  This Guaranty shall remain in full force and
effect until all obligations of the Company in respect of Loans made pursuant to
the Term C Loan Commitment and which are subject to this Guaranty have been paid
in full in cash (including,

                                       3
<PAGE>

without limitation, cash obtained by way of set-off), all obligations of the
Guarantor hereunder, including without limitation under Section 2.1, have been
satisfied and the Term C Loan Commitment of each Lender shall have terminated.
The Guarantor guarantees that the Guaranteed Obligations will be paid strictly
in accordance with the terms of the Credit Agreement and each other Loan
Document under which they arise, regardless of any law, regulation or order now
or hereafter in effect in any jurisdiction affecting any of such terms or the
rights of any Lender Party with respect thereto. The Guarantor's payment of a
portion, but not all, of the Guaranteed Obligations shall in no way limit,
affect, modify or abridge the Guarantor's liability, as set forth herein, for
any portion of the Guaranteed Obligations that has not been completely performed
or indefeasibly paid in full.

     2.4  Guaranty Unconditional.  The Guarantor agrees that the obligations of
the Guarantor hereunder shall be unconditional, absolute and irrevocable, and,
without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by (and the Guarantor hereby waives any right
to or claim of) any of the following, whether with or without notice to or
assent by the Guarantor:

            (i)     any extension, renewal, settlement, compromise,
     modification, waiver or release in respect of any obligation or duty of the
     Company under the Credit Agreement or any other Loan Document, by operation
     of law or otherwise;

            (ii)    any waiver, rescission, modification or amendment of,
     supplement to or consent to depart from any condition under or any terms of
     the Loan Documents;

            (iii)   any addition, exchange, surrender, release, impairment, non-
     perfection, failure to maintain perfection or recordation or invalidity of
     any direct or indirect security for any obligation or duty of the Company
     or any other Person under the Loan Documents or any amendment to or waiver
     or release or addition of, or consent to depart from, any other guaranty
     held by any Lender Party securing any of the obligations of the Company
     under the Credit Agreement;

            (iv)    any change in the corporate existence, structure or
     ownership of the Company or any other Person, or any insolvency,
     bankruptcy, reorganization or other similar proceeding affecting the
     Company or any other Person or its assets or any release or discharge of
     any obligation or duty of the Company or any other Person contained in the
     Loan Documents resulting from any of the foregoing;

            (v)     the existence of any claim, set-off or other rights which
     the Guarantor may have at any time against the Company or any other Person,
     whether in connection herewith or any unrelated transactions, provided that
     nothing herein shall prevent the assertion of any such claim by separate
     suit or compulsory counterclaim;

            (vi)    any invalidity, illegality, unenforceability, irregularity
     or frustration for any reason of any of the Loan Documents or any actual or
     purported obligations thereunder, or any provision of applicable law or
     regulation purporting to prohibit the

                                       4
<PAGE>

     payment by the Company of any other amount payable by the Company under the
     Loan Documents;

            (vii)   any impairment of the Company's duty of performance, the
     Company's duty to reimburse or the Guarantor's right of restitution or
     subrogation;

            (viii)  the failure of any Lender Party (A) to assert any claim or
     demand or to enforce any right or remedy against the Company or any other
     Person (including any other guarantor) under the provisions of the Credit
     Agreement, any other Loan Document or otherwise, or (B) to exercise any
     right or remedy against any other guarantor of, or any collateral securing,
     any obligations of the Company;

            (ix)    any other act or omission to act or give notice or delay of
     any kind by the Company or any other Person or any other circumstance
     whatsoever which might, but for the provisions of this section, constitute
     a legal or equitable discharge of or defense to the Guarantor's obligations
     or duties hereunder; or

            (x)     any other circumstance which might otherwise constitute a
     defense available to, or a legal or equitable discharge of, the Company,
     any surety or any guarantor.

Notwithstanding any provision of this Guaranty to the contrary, other than
Sections 2.2 and 2.7, the Guarantor shall be entitled to assert as a defense to
any claim for payment or performance of the Guaranteed Obligations that (i) such
Guaranteed Obligations are not currently due under the terms of the Loan
Documents or (ii) that such Guaranteed Obligations have previously been paid or
performed in full.

     2.5  Reinstatement, etc.  The Guarantor agrees that this Guaranty shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment (in whole or in part) of any of the Guaranteed Obligations is
rescinded or must otherwise be restored by the Agent or any Lender Party, upon
the insolvency, bankruptcy or reorganization of the Company or otherwise, as
though such payment had not been made.

     2.6  Waivers of Notices and Defenses.  The Guarantor hereby waives
promptness, diligence, notice of acceptance, presentment, demand, protest and
any notice not provided for herein with respect to any obligations of the
Company under the Credit Agreement and this Guaranty, as well as any requirement
that the Agent or any Lender protect, secure, perfect or insure any security
interest or lien, or any property subject thereto, or exercise or exhaust any
right, assert any claim or demand or enforce any remedy or take any other action
against the Company or any other Person (including any other guarantor) or any
collateral securing the obligations of the Company under the Credit Agreement
and any requirement that at any time any action be taken by any Person against
the Company or any other Person.

     2.7  Stay; Indemnity.  (a) The Guarantor, unconditionally and irrevocably,
agrees that, notwithstanding anything to the contrary herein, if a Lender Party
is stayed upon the insolvency, bankruptcy, or reorganization of the Company from
exercising its rights to enforce or exercise

                                       5
<PAGE>

any right or remedy with respect to the Guaranteed Obligations, or is prevented
from giving any notice or demand for payment or performance or taking any action
to realize on any security or collateral or is prevented from collecting any of
the Guaranteed Obligations, in any such case, by such proceeding or action, the
Guarantor shall pay or render to the Agent upon demand therefor the amount or
performance that would otherwise have been due had such rights and remedies been
permitted to be exercised by the applicable Lender Party.

          (b)  The Guarantor irrevocably and unconditionally agrees as a primary
obligation to indemnify each Lender Party from time to time on demand from and
against any loss incurred by such Lender Party as a result of any of the
obligations of the Company to pay the Guaranteed Draw Amount pursuant to the
Loan Documents being or becoming void, voidable, unenforceable or ineffective as
against the Company for any reason whatsoever, whether or not known to the Agent
or any other Person; provided, however, that the maximum amount of Guarantor's
                     -------- --------
liability under this Section 2.7(b) shall, together with all obligations under
Sections 2.1 and 2.2, not exceed the Contingent Guaranty Amount .

     2.8  No Enforcement of Subrogation.  Upon making any payment or performance
with respect to any Guaranteed Obligation hereunder, the Guarantor shall be
subrogated to the rights of the Agent against the Company with respect to such
payment or performance; provided that, in furtherance of, and not in limitation
of, the terms of the Reimbursement Agreement (including the subordination
provisions thereof) the Guarantor shall not exercise or enforce any rights which
it may acquire by way of subrogation until all of the Company's obligations
under or in respect of the Credit Agreement (and under or in respect of any
financing obtained to refinance the indebtedness described in the Credit
Agreement) have been paid in full in cash and performed in full and all
commitments to extend credit thereunder have terminated.  Any amount paid to the
Guarantor on account of any such subrogation rights in contravention of the
immediately preceding proviso shall be held in trust for the benefit of the
Agent, for the benefit of the Lender Parties, and shall immediately be paid to
the Agent, for the benefit of the Lender Parties, and credited and applied
against the Guaranteed Obligations, whether matured or unmatured.

     2.9  Reduction of Contingent Guaranty Amount and Reduction of Guaranteed
Obligations.

     (a)  The Contingent Guaranty Amount shall be reduced as follows: (i) on a
dollar-for-dollar basis by the principal amount of all Loans made in respect of
the Term C Loan Commitment that are not, at the time made, Guaranteed Draws; and
(ii) by the Agent pursuant to Section 9.08 of the Credit Agreement, to the
extent required under the Credit Agreement (but not below the then Guaranteed
Draw Amount);

     (b)  The Agent shall, subject to the last sentence of this Section 2.9(b),
reduce the Guaranteed Draw Amount (and, therefore, the Guaranteed Obligations)
as follows: (i) by giving written notice thereof to Guarantor pursuant to
Section 9.08 of the Credit Agreement, whereupon the Guaranty Draw Amount shall
be reduced on a dollar-for-dollar basis to the extent that Guaranteed Draws
previously made in respect of the Term C Loan Commitment are then supported by
Qualified Capacity Revenue from any Qualified Capacity Agreement or any other

                                       6
<PAGE>

Capacity Sales Agreement or Capacity Swap Agreement approved by Agent as
provided in the Credit Agreement and (ii) by giving written notice thereof to
Guarantor pursuant to Section 9.08 of the Credit Agreement, pursuant to which
Agent shall provide to Guarantor an irrevocable release in respect to this
Guaranty as to the amount of the reduction in question, and, at Company's
election, notice of which shall be given to Guarantor by Agent on behalf of the
Company, such amount to be added back to the Available Committed Amount.
Following receipt by the Agent of all applicable notices from the Company
requesting such reduction and the Agent's satisfaction with the form and
substance of such notices, the Agent shall promptly notify Guarantor of any such
reductions in the Guaranteed Draw Amount. For the avoidance of doubt, any
Qualified Capacity Revenue arising after the termination of the availability of
the Term C Loan Commitment shall be used to reduce the Guaranteed Draw Amount to
the extent permitted under Section 9.08 of the Credit Agreement.

     2.10  Restriction on Right of Agent to Give Notices of Guaranty Draw.
Notwithstanding anything herein or in the Credit Agreement to the contrary, the
delivery of a Notice of Guaranty Draw to Guarantor is subject to the following:

           (i)    No Notice of Guaranty Draw may be given until the Term B Loan
     Commitment of all Lenders has been fully drawn in accordance with the terms
     of the Credit Agreement;

           (ii)   No Notice of Guaranty Draw may be given until more than 50
     percent of the Term A Loan Commitment of all Lenders has been drawn in
     accordance with the Credit Agreement;

           (iii)  No Notice of Guaranty Draw may be given to the extent that the
     draw in question in respect of the Term C Loan Commitment is supported by
     Qualified Capacity Agreements in accordance with the Credit Agreement;

           (iv)   No Notice of Guaranty Draw may be given prior to the time that
     the Agent shall have received evidence reasonably satisfactory to it that
     the Company has spent (or, simultaneously with the application of the
     proceeds of the Loan in respect of the Term C Loan Commitment for which a
     Notice of Guaranty Draw is being given, will have spent or shall have
     deposited in the Construction Account provided for under the terms of the
     Credit Agreement) an amount equal to the excess of $540,000,000 over the
     sum of the fees, out-of-pocket expenses and other costs incurred by the
     Parent and the Company in connection with the issuance by the Parent of the
     Parent Senior Notes and certain of its equity interests and the other
     transactions contemplated hereunder and under the Credit Agreement;

           (v)    No Notice of Guaranty Draw may be given if, at the time in
     question, the Company is in default of its obligation to pay any of the
     fees set forth in Section 2.1 of the Reimbursement Agreement; provided that
                                                                   --------
     the Guarantor hereby agrees with the Company and the Lender Parties that,
     in the event the Agent requests the Guarantor to confirm that the Company
     is not in default in the payment of any such fees, that the Guarantor has
     no knowledge that a proposed Notice of Guaranty Draw cannot be given

                                       7
<PAGE>

     and/or that the Guarantor is not aware that this Guaranty is not in full
     force and effect, the Guarantor will provide the Agent (with a copy to the
     Company) with a prompt written response to such request.

     2.11  Payments Free and Clear of Taxes, etc.  The Guarantor hereby agrees
that:

     (a)   Any and all payments made by the Guarantor hereunder shall be made
free and clear of, and without deduction for, any and all present or future
taxes, levies, imposts, deductions, charges or withholdings, and all liabilities
with respect thereto, excluding, in the case of any Lender Party, taxes imposed
on its income, and franchise taxes imposed on it, by the jurisdiction under the
laws of which such Lender Party is organized and by any political subdivision
thereof and taxes imposed on its income, and franchise taxes imposed on it, by
the jurisdiction of such Lender Party's lending office under the Credit
Agreement and any political subdivision thereof (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). If the Guarantor shall be required by
                            -----
law to deduct any Taxes from or in respect of any sum payable hereunder to any
Lender Party

           (i)   the sum payable shall be increased as may be necessary so that
     after making all required deductions (including deductions applicable to
     additional sums payable under this Section) such Lender Party receives an
     amount equal to the sum it would have received had no such deductions been
     made,

          (ii)   the Guarantor shall make such deductions, and

          (iii)  the Guarantor shall pay the full amount deducted to the
     relevant taxation authority or other authority in accordance with
     applicable law.

     (b)   The Guarantor shall pay any present or future stamp or documentary
taxes or any other excise or property taxes, charges or similar levies which
arise from any payment made hereunder or from the execution, delivery or
registration of, or otherwise with respect to, this Guaranty (hereinafter
referred to as "Other Taxes").
                -----------

     (c)   The Guarantor hereby indemnifies and holds harmless the Agent and
each Lender Party for the full amount of Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any jurisdiction on
amounts payable under this Section) paid by the Agent or such Lender Party, as
the case may be, and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally assessed.

     (d)   Within 30 days after the date of any payment of Taxes or Other Taxes,
the Guarantor will furnish to the Agent the original or a certified copy of a
receipt evidencing payment thereof. If no Taxes or Other Taxes are payable in
respect of any payment hereunder to the Agent or any Lender Party, the Guarantor
will furnish to the Agent or such Lender Party a certificate from each
appropriate taxing authority, or an opinion of counsel acceptable to the

                                       8
<PAGE>

Agent, in either case stating that such payment is exempt from or not subject to
Taxes or Other Taxes.

     (e)   Without prejudice to the survival of any other agreement of the
Guarantor hereunder, the agreements and obligations of the Guarantor contained
in this Section shall survive the payment in full of the Guaranteed Obligations.

     2.12  Consent to Jurisdiction; Waiver of Immunities.  The Guarantor hereby
acknowledges and agrees that:

     (a)   It expressly, irrevocably and unconditionally submits, for itself and
its property, to the nonexclusive jurisdiction of the Supreme Court of the State
of New York sitting in New York County and of the United States District Court
of the Southern District of New York, and any appellate court from any thereof,
in any action or proceeding arising out of or relating to this Guaranty or any
other Loan Document, or for the recognition or enforcement of any judgment, and
the Guarantor hereby irrevocably and unconditionally agrees that all claims in
respect of such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such federal court. The
Guarantor hereby irrevocably waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Guaranty or any other Loan Document in any court referred to herein. The
Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court. The Guarantor hereby irrevocably appoints Thelen Reid &
Priest LLP (the "Process Agent"), with an office on the date hereof
                 -------------
at 40 West 57th Street, New York, New York 10019, United States, as its agent to
receive, on behalf of the Guarantor and its property, service of copies of the
summons and complaint and any other process which may be served in any such
action or proceeding. Such service may be made by mailing or delivering, return
receipt requested, a copy of such process to the Guarantor in care of the
Process Agent at the Process Agent's above address, and the Guarantor hereby
irrevocably authorizes and directs the Process Agent to accept such service on
its behalf. As an alternative method of service, the Guarantor also irrevocably
consents to the service of any and all process in any such action or proceeding
by the mailing of copies of such process to the Guarantor at its address
specified on the signature page hereof and to the attention of the person
specified thereon. The Guarantor agrees that a final judgment in any such action
or proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

     (b)   Nothing in this Section shall affect the right of the Agent or any
other Lender Party to serve legal process in any other manner permitted by law
or affect the right of the Agent or any other Lender Party to bring any action
or proceeding against the Guarantor or its property in the courts of any other
jurisdictions.

     (c)   To the extent that the Guarantor has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with

                                       9
<PAGE>

respect to itself or its property, the Guarantor hereby irrevocably waives such
immunity in respect of its obligations under this Guaranty.


                                   ARTICLE 3

                         Representations and Warranties

that the following statements are true and correct:

     3.1   Binding Obligation.  This Guaranty has been duly and validly executed
and delivered by the Guarantor and constitutes the legal, valid and binding
obligation of the Guarantor enforceable against the Guarantor in accordance with
its terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency or other similar laws affecting the enforcement of creditors' rights
generally and by equitable principles relating to the availability of equitable
remedies.

     3.2   Relationship to the Company.  As of the date hereof, the Guarantor is

the issued and outstanding capital stock of the Contractor, the agreement to
enter into the Supply Contract with the Contractor is of substantial and
material benefit to the Guarantor, the financing evidenced by the Credit
Agreement is of substantial and material benefit to the Guarantor, and the
Guarantor has reviewed and approved copies of the Supply Contract, the Credit
Agreement, and all other related documents and is fully informed of the remedies
the Agent may pursue upon the occurrence of a default under the Loan Documents.
This Guaranty will remain in full force and effect if Contractor ceases to be a
direct or indirect subsidiary of Guarantor and will remain in full force and
effect if the Supply Contract is assigned, in accordance with the terms thereof,
in whole or in part, by Company and/or the Agent (or any of Company's and/or
Agent's successors in interest to the Supply Contract).

     3.3   Incorporation and Qualification.  Guarantor is a societe anonyme duly

authority or other person or entity, or conflict with any court decree or order
applicable to the Guarantor;

<PAGE>

     (b)   conflict with any law or governmental order applicable to the
Guarantor or with any provision of the statuts (bylaws) of the Guarantor or of
any material mortgage, indenture or other agreement binding upon or applicable
to the Guarantor; or

     (c)   result in the creation or imposition of any lien on any of the
Guarantor's properties pursuant to the provisions of any such mortgage,

this Guaranty will rank at least pari passu with the claims of all its other
unsecured and unsubordinated creditors save those whose claims are preferred
solely by any bankruptcy, insolvency, liquidation or other similar laws of
general application.

     3.7   No Filing or Stamp Taxes.  Under the laws of France in force at the
date hereof, it is not necessary that this Guaranty be filed, recorded or

permitted under applicable law, cause each of its subsidiaries to, do or cause
to be done all things necessary to preserve, renew and keep in full force and
effect its legal existence and take all reasonable action to maintain all
rights, privileges and franchises material, necessary or desirable in the normal
conduct of its business except those as to which the failure to maintain such
rights, privileges and franchises could not reasonably be expected to have a
Material Adverse Effect; provided that the foregoing shall not prohibit any
                         --------
amalgamation, consolidation or merger permitted under Section 4.3.
                                                      -----------

extent permitted under applicable law, cause each of its subsidiaries to, comply
in all material respects with all laws applicable to it or its property, except

Adverse Effect.

     4.3   Amalgamation, Merger, Consolidation and Sale of Assets.  The
Guarantor will not, directly or indirectly, (x) amalgamate or consolidate or
merge with or into another Person (whether or not the Guarantor is the surviving

or assets, in one or more related transactions, to another Person; unless:

           (a)  either (i) the Guarantor is the surviving or continuing entity
     or (ii) the Person formed by, surviving or continuing after any such

     or the District of Columbia or any member country as of the date hereof of
     the European Union;

          (b)  the Surviving Entity (if other than the Guarantor) assumes all
     obligations of the Guarantor under this Guaranty, pursuant to agreements
     reasonably satisfactory to the Agent or, if such assumption is effected by
     operation of law, pursuant to confirmation of the same reasonably
     satisfactory to Agent;

     obligations hereunder;

     (a) through (d).

of all or substantially all of the properties and assets of one or more

                                 Miscellaneous

     5.1   Notices.  All notices, requests and other communications to any party
hereunder shall be in writing in the English language (including bank wire,
facsimile transmission or similar writing) and shall be given to such party at
its address, telecopy number set forth, in the case of the Guarantor, on the
signature pages hereof, or in the case of the Agent, in the Credit Agreement, or
such other address or telecopy number as such party may hereafter specify for
the purpose by notice to the other party.  Each such notice, request or other
communication shall be

                                      12
<PAGE>

at the address specified in this Section.

     5.2   No Waivers.  In addition to, and not in limitation of, Sections 2.3,
2.4 and 2.6, no failure or delay by the Agent in exercising any right, power or
privilege hereunder or under the Credit Agreement or any other Loan Document
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided under the
Credit Agreement or any other Loan Document or otherwise by law.

     5.3   Amendments and Waivers.  This Guaranty, together with the
Reimbursement Agreement, constitutes the complete agreement of the Agent and the
Guarantor with respect to the subject matter hereof and supersedes all prior or
contemporaneous negotiations, promises, covenants, agreements or
representations. No amendment, modification, termination or waiver of any
provision of this Guaranty, nor consent to the departure of the Guarantor
herefrom, shall in any event be effective unless in writing and signed by the
Agent, Guarantor, Company and Parent .

     5.4   Successors and Assigns; Beneficiaries.  This Guaranty is a continuing
Guaranty and shall be binding upon the Guarantor and its successors, transferees
and assigns; provided, however, that the Guarantor may not assign this Guaranty
             --------  -------
or transfer any of the rights or obligations of the Guarantor hereunder without
the prior written consent of the Agent.  This Guaranty shall inure to the
benefit of, and be enforceable by, the Lender Parties.  Nothing contained in
this Guaranty shall be deemed to confer upon anyone other than the parties
hereto and the other beneficiaries described in the preceding sentence any right
to insist upon or to enforce the performance or observance of any of the
obligations contained herein.  Without limiting the generality of this Section,
each Lender Party may assign or otherwise transfer (in whole or in part) all or
any portion of the Guaranteed Obligations held by it to any other Person, and
such other Person shall thereupon become vested with all rights and benefits in
respect thereof granted to such Lender Party under any Loan Document (including
this Guaranty) or otherwise.  If requested by the Agent, the Guarantor will
execute and deliver a consent, in a form reasonably requested by Agent, to any
such assignment in favor of such Lenders.

     5.5   APPLICABLE LAW.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA,
EXCLUDING ITS CONFLICTS OF LAW PROVISIONS. THE GUARANTOR HEREBY EXPRESSLY,
IRREVOCABLY AND UNCONDITIONALLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE
SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE
UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY
APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING

                                      13
<PAGE>

ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, OR FOR
RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EXPRESSLY CONSENTS TO AND
ACKNOWLEDGES THE TERMS AND AGREEMENTS SET FORTH IN SECTION 2.12.

     5.6   Judgment.  The obligations of the Guarantor in respect of this
Guaranty due to any Person shall, notwithstanding any judgment in a currency
(the "judgment currency") other than the lawful currency of the United States of
      -----------------
America ("Dollars"), be discharged only to the extent that on the Business Day
          -------
following receipt by such Person of any sum adjudged to be so due in the
judgment currency, such Person may in accordance with normal banking procedures
purchase Dollars with the judgment currency.  If the amount of Dollars so
purchased (net of all transaction costs including currency conversion costs) is
less than the sum originally due to such Person in Dollars, the Guarantor
agrees, as a separate obligation and notwithstanding any such judgment, to
indemnify such Person against such loss, and if the amount of Dollars so
purchased exceeds the sum originally due to any such Person, such Person agrees
to remit to the Guarantor, such excess.

"Reimbursement Amount") to Guarantor with interest thereon as herein provided,
 --------------------
subject to the subordination provisions of Article 5 hereof.

interest at the applicable rate specified in the Credit Agreement as to
principal of the Term C Loans that is not paid when due from the date that
Guarantor advances funds to Agent pursuant to the Guaranty until repaid as
provided herein. The Reimbursement Amount shall continue to bear interest at
such rate notwithstanding the termination of the Credit Agreement.

     3.3  Payment of Reimbursement Amount.

     (a)  Unless otherwise agreed to by the Lenders, Guarantor and Company agree
that no payment shall be made in respect of the Reimbursement Amount or interest
thereon (except as provided below in this Section 3.3(a)) prior to the Credit
Agreement Termination Date; provided that Company shall be required to make
                            --------
payments in respect of the Reimbursement Amount and interest thereon to the
extent of 50 percent of the Excess Cash Flow available for such purpose (if any)
as provided in clause ninth of Section 8.08(d) of the Credit Agreement; such
payments shall be applied first to interest and then to the Reimbursement Amount
and shall be payable on each Semi-Annual Payment Date based upon the Excess Cash
Flow for the semi-annual period ending on such Semi-Annual Payment Date.
Notwithstanding anything herein to the contrary, Guarantor and Company agree
that no payment shall be required or made in respect of the Reimbursement Amount
or interest thereon during any time when a Default or Designated Event has
occurred and is continuing or would result therefrom (it being understood and
agreed that any payment default under the Credit Agreement cured by the
Guarantor shall not be a Default or Designated Event thereunder upon and
subsequent to such cure).

     (b)  After the Credit Agreement Termination Date, the Reimbursement Amount
shall be payable in four equal semi-annual installments of principal, the first
of which (together with accrued and unpaid interest thereon) shall be due and
payable on the first Business Day following the first six-month anniversary of
the Credit Agreement Termination Date, and a like installment of principal and
interest shall be due on the first Business Day following each subsequent six-
month anniversary of such date until the fourth such date, when the
Reimbursement Amount and all accrued and unpaid interest thereon, shall be due
and payable in full. In addition, after the Credit Agreement Termination Date,
75 percent of the Company's net cash flow (determined in accordance with
GAAP) shall be applied to prepay the Reimbursement

                                       5
<PAGE>

Amount and interest thereon (with payments being applied first to interest),
with one-half (1/2) of such payments being applied in the regular order of
maturity and one-half (1/2) thereof being applied in the inverse order of
maturity; such payments shall be made on the first Business Day of each calendar
quarter based upon the net cash flow for the preceding calendar quarter.

     3.4  Prepayment of Reimbursement Amount. Company may (to the extent it has
funds available therefor) prepay the Reimbursement Amount and interest thereon,
in whole or in part, at any time without penalty or premium.

                                   ARTICLE 4

                Certain Restrictions, Guaranty and Lien Rights

     4.1  Restrictions on Declaration of Defaults and on Taking Certain Actions.
Guarantor agrees that until the earlier to occur of (i) the Credit Agreement
Termination Date, and (ii) the occurrence of an Event of Default under or in
respect of the Credit Agreement and the acceleration of payment of all
obligations thereunder, Guarantor may not, except as hereafter provided in this
Section 4.1, declare a default in respect of the Reimbursement Obligation or
otherwise accelerate payment of the Reimbursement Amount and interest thereon
under this Agreement.  The foregoing provision shall not be construed to limit
the obligation of Company to pay the fees called for under Article 2 of this
Agreement or to make payments in respect of the Reimbursement Amount and
interest thereon out of Excess Cash Flow as provided in Section 3.3(a) hereof,
and upon any failure to pay such fees or payments Guarantor may (after giving no
less than 15 days prior written notice thereof to Agent) pursue any action
available to recover the amount of the fees or payments that have not been paid.
In addition to the foregoing, Guarantor may also declare a default under this
Agreement (after giving not less than 15 days prior written notice thereof to
Agent), if the Maturity Date set forth in the Credit Agreement is amended to
provide for a later date that is more than three months after the original
scheduled Maturity Date.

     4.2  Restrictions on Indebtedness for Borrowed Money. Until such time as
all Reimbursement Amounts and all other amounts payable to Guarantor under this
Agreement have been paid in full and this Agreement has been terminated, the
Company agrees that its and its subsidiaries' total Indebtedness for Borrowed
Money shall not exceed $500,000,000 in the aggregate.

     4.3  Restriction on Payment on Parent Senior Notes.  Until such time as all
Reimbursement Amounts and all other amounts payable to Guarantor under this
Agreement have been paid in full and this Agreement has been terminated, the
Parent shall not make any payments in respect of principal on the Parent Senior
Notes.

     4.4  Restriction on Redemptions and Reduction in Share Capital.  During any
time while the Guaranty is in effect or there is outstanding and unpaid any
Reimbursement Obligation or other amount payable to Guarantor hereunder, then
the Company and Parent shall not redeem, reacquire, or buy back any outstanding
capital stock of the Company or Parent, as applicable, nor

                                       6

otherwise reduce its outstanding share capital, provided that foregoing
provision shall not restrict the Parent from redeeming (i) up to $31,000,000 of
its outstanding capital stock from the proceeds of the Company high yield debt
and equity offerings and (ii) its capital stock as required in connection with
its stock option plans and employment agreements, provided that redemptions
pursuant to this clause (ii) shall not exceed $10,000,000. In addition to the
foregoing, following the closing and funding of the Parent Senior Notes and the
sale of the equity interests in Parent described in the Credit Agreement, and
after any Notice of Guaranty Draw is given, the outstanding share capital of the
Company shall not be less than the excess of $540,000,000 over the sum of the
fees, out-of-pocket expenses and other costs incurred by the Parent and the
Company in connection with the issuance by the Parent of the Parent Senior Notes
and certain of its equity interests and the other transactions contemplated
hereunder and under the Credit Agreement.

     4.5  Additional Guaranties and Lien Rights.  After the occurrence of the
Credit Agreement Termination Date, Company agrees that it shall, to the extent
granted to the Agent, and shall cause all of its Subsidiaries to the extent
provided under the Credit Agreement (the "Subject Subsidiaries" which directly
                                          --------------------
or indirectly own any interest in the System) to (i) guaranty Company's
obligations hereunder, and (ii) grant a lien on their interests in the System,
to secure performance of Company's obligations under this Agreement.  The
documentation evidencing such guaranties and liens shall be in substantially the
same form as that executed in conjunction with the Credit Agreement.  Guarantor
agrees that it will not register, make any filing or take any similar action in
respect of such future lien until after the occurrence of the Credit Agreement
Termination Date.

     4.6  Negative Pledge.  So long as the Guaranty is in effect or any
Reimbursement Amount or any other amount is payable to Guarantor pursuant to
this Agreement, the Company and the Subject Subsidiaries shall not grant any
liens or security interests on or in any of their assets to secure the payment
of any borrowings, nor shall the Company or the Subject Subsidiaries guaranty
the payment of any borrowings of any other person or entity, except that the
foregoing provision shall not restrict the following:  (i) any liens or security
interests or guarantees granted or made in connection with or with respect to

securing the obligations described in the preceding clause (A) or guaranteed by
any or all of the Persons guarantying such obligations; (ii) purchase money

Agent to notify Guarantor that the Guaranteed Draw Amount shall be reduced to
the extent of such amount of Qualified Capacity Revenue. In connection with the

                                   ARTICLE 5

                                 SUBORDINATION

     5.1  Agreement to Subordinate. Each of Guarantor and Company agrees that
the Subordinated Obligations are and shall be subject, subordinate and rendered
junior, to the extent and in the manner hereinafter set forth, in right of
payment, to the prior payment in full in cash

                                       8
<PAGE>

of all Senior Obligations. Guarantor acknowledges and agrees that these
subordination provisions are, and are intended to be, an inducement and a
consideration to each holder of any Senior Obligations, whether such Senior
Obligations were created or acquired before or after the execution and delivery
of this Agreement, to acquire and continue to hold such Senior Obligations and
such holder of Senior Obligations shall be deemed conclusively to have relied on
such subordination provisions in acquiring and continuing to hold such Senior
Obligations.

     5.2  Payment Restrictions.  Company shall not make, and Guarantor shall not
receive or accept, any payment in respect of the Subordinated Obligations if a
Default or Designated Event has occurred and is continuing or would result
therefrom, unless otherwise agreed to by the Lenders.  For purposes of these
provisions, "payment" in respect of the Subordinated Obligations shall include
any direct or indirect payment or distribution from any source, whether in cash,
property or securities, by set-off or otherwise, in respect of principal,
premium, interest or otherwise, including in connection with any redemption or
purchase thereof or any recovery on any claim for rescission or damages.

     5.3  Insolvency and Related Proceedings. (a) Upon any payment, distribution
or other transfer of all or any of the assets of Company in the event of

          (i)    any insolvency or bankruptcy case or proceeding, or any
     receivership, liquidation, reorganization or other similar case or
     proceeding in connection therewith, relative to Company or to its assets,

          (ii)   any liquidation, dissolution or other winding up of Company,
     whether voluntary or involuntary and whether or not involving insolvency or
     bankruptcy, or

          (iii)  any assignment for the benefit of creditors, any scheme of
     arrangement or reconstruction of creditor claims, or any marshaling of
     assets and liabilities of Company,

then, and in any such event, unless the Lenders shall otherwise agree in
writing, the holders of the Senior Obligations shall receive payment in full in
cash of all amounts due or to become due (whether or not the Senior Obligations
have been declared due and payable prior to the date on which the Senior
Obligations would otherwise have become due and payable) on or in respect of all
Senior Obligations before the Guarantor or anyone claiming through or on its
behalf (including any receiver, trustee, or otherwise) are entitled to receive
any payment on account of the Subordinated Obligations, and to that end any
payment or distribution of any kind or character, whether in cash, property or
securities, which may be payable or deliverable in respect of the Subordinated
Obligations in any such case, proceeding, dissolution, liquidation or other
winding up or event, shall be paid or delivered directly to the Agent for the
application (in the case of cash) to, or as collateral (in the case of non-cash
property or securities) for, the payment or prepayment of the Senior Obligations
until the Senior Obligations shall have been paid in full in cash.

                                       9
<PAGE>

     (b)  If any proceeding, liquidation, dissolution or winding up referred to
in clause (a) above is commenced by or against Company,
   ----------

          (i)  the Agent is hereby irrevocably authorized and empowered (in its
     own name or in the name of Company, Guarantor or otherwise), but shall have
     no obligation, to demand, sue for, collect and receive every payment or
     distribution in respect of the Subordinated Obligations and give
     acquittance therefor and to file claims and proofs of claim and take such
     other action (including, without limitation, voting the Subordinated
     Obligations or enforcing any security interest or other lien securing
     payment of the Subordinated Obligations) as the Agent may deem necessary or
     advisable for the exercise or enforcement of any of the rights or interests
     of the Lender Parties, including the Agent, hereunder; provided that
                                                            --------
     Guarantor shall be permitted to take such action so long as, in the
     reasonable judgment of the Agent, the taking of such action is not
     inconsistent with the terms hereof and the parties agree that any party
     taking any such action hereunder shall promptly notify the other party upon
     the taking of any such action; provided, however, that if the Agent takes
                                    --------  -------
     any such action, the Agent shall apply all proceeds first, to the payment
                                                         -----
     of the costs of enforcement of these subordination provisions, and second,
                                                                        ------
     to the pro rata payment, prepayment and/or cash collateralization of the
            --- ----
     Senior Obligations in a manner consistent with the provisions set forth in
     the Credit Agreement; and

          (ii) the Guarantor shall duly and promptly take such action as the
     Agent may reasonably request (A) to collect the Subordinated Obligations
     for account of the holders of Senior Obligations and to file appropriate
     claims or proofs of claim in respect of the Subordinated Obligations, (B)
     to execute and deliver to the Agent such powers of attorney, assignments,
     or other instruments as the Agent may reasonably request to enable them to
     enforce any and all claims with respect to, and any security interests and
     other liens securing payment of, the Subordinated Obligations and (C) to
     collect and receive any and all payments or distributions which may be
     payable or deliverable upon or with respect to the Subordinated
     Obligations.

     5.4  Payment Over. All payments, distributions or other transfers of assets
of Company, whether in cash, property or securities upon or with respect to the
Subordinated Obligations which are received by the Guarantor contrary to the
provisions of this Agreement shall be received in trust for the pro rata benefit
                                                                --- ----
of holders of Senior Obligations, shall be segregated from other funds and
property held by the Guarantor and shall be forthwith paid over to the Agent in
the same form as so received (with any necessary endorsement) to be applied, pro
                                                                             ---
rata (in the case of cash) to, or held as collateral (in the case of noncash
- ----
property or securities) for, the payment or prepayment of the Senior
Obligations, whether matured or unmatured, in accordance with the terms of this
Agreement.

     5.5  Specific Performance. The Agent is hereby authorized to demand
specific performance of these subordination provisions, whether or not Company
or Guarantor shall have complied with any of the provisions hereof applicable to
it, at any time when Guarantor shall have failed to comply with any of the
provisions of this Agreement applicable to it. Guarantor hereby irrevocably
waives any defense (other than the defense of payment in full in cash of the

                                       10
<PAGE>

Senior Obligations) based on the adequacy of a remedy at law which might be
asserted as a bar to such remedy of specific performance.

     5.6  Subordination Legend; Further Assurances. Guarantor will cause each
note and instrument (if any) evidencing the Subordinated Obligations to be
endorsed with the following legend:

          "The indebtedness evidenced by this instrument is subordinated
     to the prior payment in full in cash of the Senior Obligations (as
     defined in the Reimbursement Agreement, dated as of July ___, 1999)
     pursuant to, and to the extent provided in, the Reimbursement
     Agreement by the maker hereof and payee named herein in favor of the
     holders of such Senior Obligations and any person now or hereafter
     designated as their agent."

Each of Guarantor and Company hereby agrees to mark its books of account in such
a manner as shall be effective to give proper notice of the effect of this
Agreement and will, in the case of any Subordinated Obligation not evidenced by
any note or instrument, following the occurrence and continuation of a Default,
or Designated Event, upon the Agent's request, cause such Subordinated
Obligation to be evidenced by an appropriate note or instrument or instruments
endorsed with the above legend.  Each of Guarantor and Company will at its
expense and at any time and from time to time promptly execute and deliver all
further instruments and documents and take all further action that may be
necessary or that the Agent may reasonably request to protect any right or
interest granted or purported to be granted hereunder or to enable holders of
Senior Obligations or the Agent to exercise and enforce their rights and
remedies hereunder.

     5.7  No Change in or Disposition of Subordinated Obligations.  Guarantor
will not, without the prior written consent of the Agents (a) sell, assign,
transfer, endorse, pledge, encumber or otherwise dispose of any of the
Subordinated Obligations ("Transfer") or (b) permit the terms of any of the
                           --------
Subordinated Obligations to be changed in such a manner as to have an adverse
effect upon the rights or interests of holders of Senior Obligations or the
Agent unless, in the case of any purported Transfer, either (i)

     (a)  the proposed assignee is a societe anonyme established or existing
          under the laws of France or a corporation organized under the laws of
          Bermuda, the United States, any state thereof or the District of
          Columbia, or any member country as of the date hereof of the European
          Union;

     (b)  the proposed assignee assumes all obligations of the Guarantor
          hereunder, pursuant to agreements reasonably satisfactory to the
          Agent;

     (c)  the proposed assignee has a long-term senior unsecured debt rating of
          BBB-(or better) from Standard & Poor's Services and Baa3 (or better)
          from Moody's Investor Service, Inc.; and

                                       11
<PAGE>

     (d)  the Guarantor delivers to the Agent an officer's certificate and an
          opinion of counsel reasonably acceptable to the Agent, each stating
          that such sale, assignment or transfer complies with the preceding
          clauses (a) through (c);

     or (ii) the proposed assignee agrees to be bound by the subordination
provisions of this Agreement pursuant to an agreement reasonably satisfactory to
the Agent and such Transfer does not cause or effect any Transfer of any of
Guarantor's obligations under this Agreement and in any event Guarantor remains
primarily liable in respect of all of its obligations hereunder.

     5.8  Obligations Hereunder Not Affected.  All rights and interest of
holders of Senior Obligations and the Agent hereunder, and all agreements and
obligations of the Guarantor and Company hereunder, shall remain in full force
and effect irrespective of:

          (a)  any lack of validity or enforceability of any document evidencing
     the Senior Obligations;

          (b)  except as contemplated in the last sentence of Section 4.1, any
     change in the time, manner or place of payment of, or any other term of,
     all or any of the Senior Obligations, or any other amendment or waiver of
     or any consent to departure from any of the documents evidencing or
     relating to the Senior Obligations;

          (c)  any exchange, release or non-perfection of any collateral, or any
     release or amendment or waiver of or consent to departure from any guaranty
     or other document, for all or any of the Senior Obligations;

          (d)  any failure of any holder of Senior Obligations or the Agent to
     assert any claim or to enforce any right or remedy against any other party
     hereto under the provisions of this Agreement, the Credit Agreement or any
     other document;

          (e)  any reduction, limitation, impairment or termination of the
     Senior Obligations for any reason, including any claim of waiver, release,
     surrender, alteration or compromise, and shall not be subject to (and
     Company and Guarantor hereby waive any right to or claim of) any defense
     (other than the defense of payment in full in cash of the Senior
     Obligations) or setoff, counterclaim, recoupment or termination whatsoever
     by reason of invalidity, illegality, nongenuineness, irregularity,
     compromise, unenforceability of, or any other event or occurrence
     affecting, any Senior Obligation; and

          (f)  any other circumstance which might otherwise constitute a defense
     (other than the defense of payment in full in cash of the Senior
     Obligations) available to, or a discharge of, Company in respect of the
     Senior Obligations or Guarantor in respect of these subordination
     provisions.

These subordination provisions shall continue to be effective or be reinstated,
as the case may be, if at any time any payment of any of the Senior Obligations
is rescinded or must otherwise be

                                       12
<PAGE>

returned by any holder of Senior Obligations or the Agent upon the insolvency,
bankruptcy or reorganization of Company or otherwise, all as though such payment
had not been made.

     5.9  Miscellaneous Subordination Provisions. (a) The subordination
provisions contained herein are solely for the benefit of the holders from time
to time of Senior Obligations and their representatives, assignees and
beneficiaries and may not be rescinded, cancelled, amended or modified in any
way other than any amendment or modification that would not adversely affect the
rights of any holder of Senior Obligations. Guarantor shall not subordinate any
Subordinated Obligations to any indebtedness or obligation of Company other than
the Senior Obligations.

          (b)  No right of any present or future holder of any Senior
Obligations to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of
Company or by any act or failure to act, in good faith, by any such holder, or
by any non-compliance by Company with the terms, provisions and covenants of
this Agreement, regardless of any knowledge thereof any such holder may have or
be otherwise charged with.

          (c)  These subordination provisions shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be,
if at any time payment and performance of the Senior Obligations is, pursuant to
applicable law, avoided, recovered, or rescinded or must otherwise be restored
or returned by any holder of Senior Obligations, whether as a "voidable
preference," "fraudulent conveyance," "fraudulent transfer," or otherwise, all
as though such payment or performance had not been made.

Dear Sirs

GlobeNet Communications Group Limited (the "Company")
Registration Statement on Form S-4 (No. 333-86461)

We have acted as special legal counsel in Bermuda to the Company in connection
with its filing with the U.S. Securities and Exchange Commission of a
Registration Statement on Form S-4 (File No. 333-86461) (the "Registration
Statement") with respect to the proposed offer by the Company to exchange
US$300,000,000 aggregate principal amount of the Company's 13% Series B Senior
Notes Due 2007 (the "Exchange Notes") for an equal principal amount of its
outstanding 13% Senior Notes Due 2007 (the "Restricted Notes"). The Exchange
Notes are to be issued pursuant to an Indenture dated as of 14 July, 1999
between the Company and Bankers Trust Company, as Trustee (the "Indenture").

For the purposes of giving this opinion, we have examined the following
documents:

     (i)   a copy of the Registration Statement;

     (ii)  a copy of the Indenture;

     (iii) a form of the Notes.

The documents listed in items (i) through (iii) above are herein sometimes
collectively referred

to as the "Documents" (which term does not include any other instrument or
agreement whether or not specifically referred to therein or attached as an
exhibit or schedule thereto).

We have also reviewed the memorandum of association and the bye-laws of the
Company, minutes of various meetings of its directors (the "Minutes"), and such
other documents and made such enquiries as to questions of law as we have deemed
necessary in order to render the opinion set forth below.

We have assumed (a) the genuineness and authenticity of all signatures and the
conformity to the originals of all copies (whether or not certified) examined by
us and the authenticity and completeness of the originals from which such copies
were taken, (b) that where a document has been examined by us in draft form, it
will be or has been executed in the form of that draft, and where a number of
drafts of a document have been examined by us all changes thereto have been
marked or otherwise drawn to our attention, (c) the capacity, power and
authority of each of the parties to the Documents, other than the Company, to
enter into and perform its respective obligations under the Documents, (d) the
due execution of the Documents by each of the parties thereto, other than the
Company, and that each of the parties to the Documents physically gave such
Documents to the other parties thereto, (e) the accuracy and completeness of all
factual representations made in the Documents and other documents reviewed by
us, (f) that the resolutions contained in the Minutes remain in full force and
effect and have not been rescinded or amended, (g) that the Company is entering
into the Documents pursuant to its business of providing international
telecommunications services, (h) that there is no provision of the law of any
jurisdiction, other than Bermuda, which would have any implication in relation
to the opinions expressed herein, (i) the validity and binding effect under the
laws of the State of New York (the "Foreign Laws") of the Documents which are
expressed to be governed by such Foreign Laws in accordance with their
respective terms.

The obligations of the Company under the Documents (a) will be subject to the
laws from time to time in effect relating to bankruptcy, insolvency,
liquidation, possessory liens, rights of set off, reorganisation, amalgamation,
moratorium or any other laws or legal procedures, whether of a similar nature or
otherwise, generally affecting the rights of creditors, (b) will be subject to
statutory limitation of the time within which proceedings may be brought, (c)
will be subject to general principles of equity and, as such, specific
performance and injunctive relief, being equitable remedies, may not be
available, (d) may not be given effect to by a Bermuda court, whether or not it
was applying the Foreign Laws, if and to the extent they constitute the payment
of an amount which is in the nature of a penalty and not in the nature of
liquidated damages. Notwithstanding any contractual submission to the
jurisdiction of specific courts, a Bermuda court has inherent discretion to stay
or allow proceedings in the Bermuda courts.

We express no opinion as to the enforceability of any provision of the Documents
which provides for the payment of a specified rate of interest on the amount of
a judgment after the date of judgment or which purports to fetter the statutory
powers of the Company.

                              INDEMNITY AGREEMENT
                              -------------------


     THIS Agreement is made as of and effective the 14th day of July, 1999
between Anthony J. Bolland, of Boston, Massachusetts, USA ("GlobeNet Director"),
and GlobeNet Communications Group Limited, a company incorporated under the laws
of Bermuda ("GlobeNet").

     WHEREAS the GlobeNet Director has agreed to act as a director of GlobeNet,
at the request of GlobeNet;

     NOW THEREFORE THIS AGREEMENT WITNESSETH that in consideration of the sum of
$1 now paid by the GlobeNet Director to GlobeNet (the receipt of which is hereby
acknowledged) and for other good and valuable consideration, it is hereby agreed
as follows:

     1.  GlobeNet acknowledges that the GlobeNet Director has been requested by
GlobeNet to act as a GlobeNet Director.

     2.  GlobeNet agrees to indemnify and save harmless the GlobeNet Director,
his heirs and legal representatives, to the fullest extent permitted by Section
98 of the Companies Act 1981 against all costs, charges, liability, damages, and
expenses, including an amount paid to settle an action or to satisfy a judgment,
reasonably incurred by him in respect of any civil, criminal or administrative
action or proceeding to which he is made a party by reason of, or in any
connection with him, being or having been a director of GlobeNet if: (a) the
GlobeNet Director acted in his capacity as a Director and (b) in the case of a
criminal or administrative action or proceeding that is enforced by a monetary
penalty, the GlobeNet Director had reasonable grounds for believing that his
conduct was lawful.

     3.  Without prejudice to the generality of section 2, but for the purposes
of Section 97 of the Companies Act 1981, or otherwise for the purpose of
determining whether the GlobeNet Director was acting within his capacity as a
director, the termination of any civil, criminal or administrative action or
proceeding by judgment, order, settlement, conviction or similar or other result
shall not, of itself, create a presumption either that the GlobeNet Director did
not act honestly and in good faith with a view to the best interests of GlobeNet
or that, in the case of a criminal or administrative action or proceeding that
is enforced by a monetary penalty, the GlobeNet Director did not have reasonable
grounds for believing that his conduct was lawful.

     4.  If approval of any court is required in respect of any indemnification
of the GlobeNet Director by GlobeNet, then GlobeNet shall promptly make
application for approval of such court to indemnify the GlobeNet Director, his
heirs and legal representatives, against all costs, charges, liability, damages,
and expenses reasonably incurred by him/her in connection with such action if:
(a) the GlobeNet Director acted honestly and in good faith with a view to the
best interests of GlobeNet; and (b) in the case of a criminal or administrative
action or proceeding that is enforced by a monetary penalty, the GlobeNet
Director had reasonable grounds for believing that his/her conduct was lawful.

     5.  Subject as hereinafter provided, GlobeNet shall pay all amounts covered
by this Agreement and incurred or reasonably likely to be incurred, by the
GlobeNet Director, his heirs and legal representatives, in defending any civil,
criminal or administrative action or proceeding to which the GlobeNet Director
or his heirs and legal representatives are made a party by reason of, or in any
connection with, the GlobeNet Director being or having been a director of
GlobeNet in advance of such action or proceeding. In respect of any such action
or proceeding, including an action by or on behalf of GlobeNet to procure
judgment in its favour and in respect of which GlobeNet is obligated to make
application for approval of the court to indemnify the GlobeNet Director, or his
heirs and legal representatives, GlobeNet shall pay all such amounts in advance
of such action or proceeding only upon receipt of an undertaking satisfactory to
GlobeNet by or on behalf of the GlobeNet Director, or his heirs and legal
representatives, to repay such amount if the court determines that the GlobeNet
Director, or his heirs and legal representatives, is not entitled to be
indemnified.

     6.  The GlobeNet Director shall not have any right to indemnification
hereunder in respect of any settlement of any civil, criminal or administrative
action or proceeding without GlobeNet's consent to such settlement, such consent
not to be unreasonably withheld.

     7.  This Agreement shall not operate to abridge, limit, restrict, or
exclude any other defences or rights, in law or in equity, to which the GlobeNet
Director may be entitled by operation of law or under any statute, bye-law of
GlobeNet, agreement, vote of shareholders of GlobeNet, vote of disinterested
directors of GlobeNet, or otherwise.

     8.  This Agreement shall be deemed to have been made in and shall be
construed in accordance with the laws of Bermuda applicable therein, and the
parties hereby agree that any claims, disputes or questions arising out of or in
relation to this Agreement may be submitted to the jurisdiction of the courts of
Bermuda.  Each of the parties hereto irrevocably attorns to the non-exclusive
jurisdiction of the courts of Bermuda.

     9.  This Agreement and the benefit and obligation of all covenants herein
contained shall enure to the benefit of and be binding upon the heirs,
executors, administrators, legal personal representatives and successors and
assigns of each of the parties hereto.

     10. This Agreement shall continue until and terminate upon the later of:
(a) fifteen (15) years after the date that the GlobeNet Director shall have
ceased to serve as a director of GlobeNet; or (b) the final termination of all
pending proceedings in respect of which the GlobeNet Director is granted rights
of indemnification or advancement of expenses. This Agreement shall be binding
upon GlobeNet and its successors and assigns and shall inure to the benefit of
the GlobeNet Director and his heirs, executors and administrators.

              faith judgment it would be advisable to obtain the advice of
              counsel, accountants or other advisors prior to cooperating with
              or assisting Purchaser or taking any action, unless in each case,
              Purchaser has agreed to reimburse Contractor under the foregoing
              proviso.

          7.  As part of the Work, the Contractor shall obtain at its cost and
              expense, on Purchaser's behalf, any import license or other
              official authorization and carry out all customs formalities
              necessary for the importation or exportation of Supplies in
              connection with such Work. The Purchaser agrees to be the

              Exporter of Record/Consignee on its behalf. Purchaser must provide
              a Letter of Authorization from any third party designate stating
              it agrees to be the Importer or Exporter of Record on Purchaser's
              behalf and identify the name and address of the designated
              Importer or Exporter of Record.

          8.  The Supplies to be installed or held on land shall, at the cost
              and expense of Contractor, be delivered to, unloaded and stored at
              the agreed point at the named place of destination and shall be
              consigned at such point to the Purchaser; provided, that risk of
              loss and title to the Supplies shall pass in accordance with Sub-
              Article 9(F).

     C.   Withholding Tax

          1.  If any withholding for any Tax other than a Contract Tax is
              required by any Law as modified by applicable treaties in respect
              of any payment to the Contractor, the Purchaser shall (i) withhold
              the appropriate amount from such payment, and (ii) pay such amount
              to the relevant authorities in accordance with applicable Laws.

          2.  To the extent reasonably possible, before withholding any such Tax
              in respect of any payment to the Contractor, the Purchaser shall
              inform the Contractor of the withholding requirement.

          3.  The Purchaser shall provide to the Contractor, as soon as
              reasonably practicable, a certified copy of an official tax
              receipt for any Tax which is withheld from any payment due to the
              Contractor. All such receipts shall be in the name of the
              Contractor. The Contractor agrees to complete accurately and
              timely provide to the Purchaser or, if required, to the applicable
              taxing authority, such forms, certifications or other documents as
              may be requested in a timely manner by the Purchaser, in order to
              allow it to make payments to the Contractor without any deduction
              or withholding on account of such Taxes (or at a reduced rate
              thereof) or to receive a refund of any amounts deducted or
              withheld on account of such Taxes.

C.  Payment Procedures

        1.  The Purchaser shall pay the Contractor, and the Contractor shall
            accept payment, in accordance with this Article 5 (Terms of
            Payment). All payments due and owing to the Contractor shall be paid
            to the Prime Contractor (and each invoice shall so provide) and
            payment to the Prime Contractor shall be deemed payment to the
            Contractor. Any amounts

                                                                         Page 16
<PAGE>

         received by the Prime Contractor shall be deemed to have been received
         by the Prime Contractor in its capacity as agent of the Contractor. The
         Prime Contractor shall pay such amounts to the Contractor net of any
         applicable taxes or levies that may be imposed on the Contractor.

     2.  Purchaser agrees to pay an initial payment to Contractor in the amount
         of US$62,086,157 on July 15, 1999. Failure to receive this payment
         shall entitle Contractor to immediately suspend Work hereunder.

     3.  Invoices shall be given to the Purchaser and the Independent Engineer
         on the fifteenth (15th) day of any month, subject to Sub-Article
         5(C)(5) below, and shall be due and payable on the later to occur of
         the last day of the next month or forty-five (45) days from the
         Purchaser's receipt of the invoice (the "Payment Date").
                                                  ------------

     4.  Invoices or amounts owed which are not paid when due shall accrue late
         payment charges from the day, following the day, on which payment was
         due until the day on which it is paid. Invoices for such extended
         payment charges shall not be issued for an amount less than U.S.
         $1,000. Late payment charges shall be computed at the rate of the Prime
         Rate plus 2%.

     5.  In the event that the Purchaser has an objection to any invoice, the
         Purchaser shall notify the Contractor by the Payment Date and the
         Purchaser and Contractor shall make every reasonable effort to settle
         promptly the dispute concerning the payment(s) in question. Failure to
         notify or pay the Contractor by the Payment Date shall entitle the
         Contractor, under Sub-Article 15(B), to suspend Work hereunder. In the
         event such dispute is not settled by the Payment Date, the Prime
         Contractor and the Purchaser will execute and deliver a Payment Escrow
         Agreement substantially in the form of Exhibit C hereto, with such
         changes therein as the Payment Escrow Agent may reasonably request, and
         the Purchaser will have the right to withhold payment of the disputed
         amount(s) (or withhold from the invoice amount a sum equal to the
         amount purportedly owing by Contractor to Purchaser hereunder) so long
         as it deposits, in full, such disputed amount(s) into the Dispute
         Account. In the event payment is made under the Payment Escrow
         Agreement, Contractor shall continue to perform the Work hereunder.

         (a)  Provided such disputed amount is placed into the Dispute Account
              in a timely manner, the Purchaser shall not be deemed to be in
              breach of or in default for failing to pay Contractor.

         (b)  The Payment Escrow Agent will distribute the disputed amount in
              accordance with the terms of the Payment Escrow Agreement.

         (c)  In addition, the prevailing Party shall be entitled to receive
              from the Dispute Account an amount equal to the interest earned by
              the

                                                                         Page 17
<PAGE>

                    Payment Escrow Agent on the distributed, disputed amount,
                    which shall be distributed by the Payment Escrow Agent under
                    clause (b) above.

          6.  The Purchaser shall make timely payments for that portion of the
              invoice not in dispute in accordance with Sub-Article 5(C) or such
              payments will be assessed extended payment charges as set forth in
              Sub-Article 5(C)(4). Pending resolution of the dispute, the
              Purchaser may not withhold payment (unless also subject to
              dispute) on any other invoice concerning different goods and/or
              services submitted by Contractor.


6    Contract Variations
     -------------------

     A.  Either Party may request, during construction of the System, by written
order, a contract variation requiring additions or alterations to, deviations or
deductions from the System ("Contract Variation"). If the other Party consents,
                             ------------------
in its sole discretion, this change will be formalized as an amendment to this
Contract by a Contract Variation; provided, that the Contractor will not
                                  --------
unreasonably withhold its consent to a Contract Variation requested by the
Purchaser.

     B.  A Contract Variation shall not become effective unless and until the
price adjustment, the terms and schedule of payment and the extension or
reduction of time and all other terms have been mutually agreed upon by the
Parties (and the Parties shall act reasonably and in good faith in connection
with all such terms) and such Contract Variation is signed by an authorized
representative of each of the Purchaser and the Prime Contractor. Each Contract
Variation shall be incorporated as an amendment to this Contract.

     C.  Contractor may seek a Contract Variation for any change, after the date
hereof, of any Law (except those, and to the extent, affecting only Taxes or
wages) which requires a change in the Work or affects the costs (other than
Taxes or wages) incurred or to be incurred by the Contractor or any combination
of the foregoing and Purchaser shall agree to any such change in Work as may be
required and, subject to Sub-Article 4(A), to an equitable adjustment to the
Contract Price.  In such event, Contractor shall use its best endeavors to
minimize any increase in cost arising out of a change in Law.  As of the date
hereof, neither Party has Actual Knowledge of any proposed change in any Law
that would require a change in the Work.

     D.  The Parties shall negotiate appropriate Contract Variations in good
faith to finalize the scope of the Work required for the land acquisition and/or
lease and civil works (i.e., construction) associated with the provision of
                       ----
cable stations, and access thereto, such negotiations to be completed by July
15, 1999.  Subject to completion of negotiations by the date specified in the
preceding sentence, no Contract Variation referred to in this Sub-Article 6(D)
shall result in an extension of the Scheduled RFS Date, the Segment 6 Scheduled
RFS Date or the Segment 4/5 Scheduled RFS Date.

                                                                         Page 18

7    Responsibilities for Permits/Landing Licenses; Compliance with Laws
     -------------------------------------------------------------------

     A.  The Purchaser shall reasonably cooperate with and assist the Contractor
to obtain all Permits, to the extent that Purchaser's cooperation and assistance
are necessary for Contractor to expeditiously and cost-efficiently obtain such
Permits. The Purchaser agrees to respond promptly to any such request from
Contractor. Further, the Purchaser agrees that it will not impede or interfere
with Contractor's activities or Contractor's abilities to perform its
obligations. Upon notice from Contractor with respect to a Permit or receipt by
Purchaser of a copy of a Permit, Purchaser shall use reasonable efforts to
fulfill all conditions of such Permit and perform all responsibilities
thereunder, except to the extent that such conditions or responsibilities are
those of the Contractor under or relating to the Work or as provided in Sub-
Articles 4(A)(4) and 7(B). Contractor will inform Purchaser as to any such
conditions or responsibilities that are not ordinary and routine and obtain
Purchaser's written consent thereto prior to arranging for any such Permit.

     B.  The Contractor shall have the responsibility for obtaining and shall
use its best efforts to obtain as soon as reasonably practicable and at
Contractor's cost and expense, all Permits. With respect to any interest in real
property, Contractor shall (unless Purchaser otherwise requires), to the extent
practicable, obtain title directly in the name of the Purchaser or its designee.
The Contractor will cause, at its cost and expense, all Permits not issued in
the name of Purchaser to be freely assignable to Purchaser, and to be assigned
to Purchaser at the time title to the System is transferred to Purchaser
pursuant to this Contract. Contractor will cause all Permits to provide that any
payments thereunder are the obligation of Contractor and not of Purchaser.

     C.  The Purchaser shall be responsible for obtaining, at its expense (but
shall not be liable for its failure to obtain), Landing Licenses. The Contractor
will cooperate with the Purchaser in connection therewith.

     D.  Any delay in obtaining or failure to obtain any Permit shall constitute
Force Majeure and be treated as described in Article 17 (Force Majeure), except
to the extent such delay is a result of Contractor's negligence, willful
misconduct or breach of this Contract.

     E.  Except with respect to variations necessitated by complying with any
changes, enacted after the date hereof, in any Laws (the costs with respect to
which shall be borne by the Contractor and/or the Purchaser to the extent
provided in this Contract), the Contractor shall be responsible for the payment
of any and all costs incurred as a result of the need to vary design, drawings,
plans or procedures to comply with any of the circumstances set forth in this
Article. The Contractor shall, before making any variations from the designs,
drawings, plans or procedures that may be necessitated by so complying with any
Laws and that would represent a change to the design of the System, give to the
Purchaser written notice, specifying the variations proposed to be made, and the
reasons for making them. As of the date hereof, neither Party has Actual
Knowledge of any proposed changes in the Laws which would necessitate any such
variation.

     F.  The Contractor shall (i) give all notices required by any Laws to be
given to any authority and (ii) perform or permit the performance by authorized
persons of any inspection required by the said Laws in connection with Work
performed under this Contract.

                                                                         Page 19
<PAGE>

     G.  As part of the Initial Contract Price, the Contractor shall obtain, at
its own risk and expense, any export and import license and other official
authorization and carry out all customs formalities for the exportation and
importation of Supplies and, where necessary, for their transit through another
country.

     H.  Further to the Permit Listing in Exhibit B, within 30 days after the
date of execution of this Contract, the Contractor will prepare and deliver to
the Purchaser an updated list of Permits that to its knowledge are required to
be obtained under current Law in order to complete the Work and shall update
such list from time to time as it becomes aware of changes in Permit
requirements. Such list, as updated from time to time, shall set forth the
projected dates of filing for such Permits and an estimate of when such Permits
are expected to be obtained. Without limiting Contractor's liabilities in
respect of Sub-Articles 7(B) and (G), Contractor shall have no liability in
respect of the accuracy of the information furnished under this Sub-Article,
except in the case of gross negligence or willful misconduct.

     I.  Contractor, in performing the Work, shall comply with all applicable
Laws, including, without limitation, all employment, safety and environmental
laws.

     J.  Contractor is responsible for notifying any third party cable or
pipeline owner or operator whose system could be impacted by a System cable
crossing or by the proximate location of any portion of the System.


8    Route Survey
     ------------

     A.  The Contractor shall conduct the Route Survey and select the cable
route for the System (other than with respect to BUS-1) in accordance with the
information in the Final Survey Report. Contractor shall be permitted to make
changes, at its discretion, to the route selection (other than with respect to
BUS-1), if necessary for operational reasons without additional cost to
Purchaser.

     B.  Any changes to the route selection requested by Purchaser shall be
treated as a Contract Variation in accordance with Article 6 (Contract
Variations).


9    Acceptance
     ----------

     A.  General

          1.  The Acceptance Testing shall be performed by the Contractor at its
              cost and expense. The Purchaser and its designated representatives
              (including the Independent Engineer) may observe, at their own
              expense, the Contractor's tests and review the test results.
              Purchaser may request and conduct any additional tests, at its own
              expense (except where the additional test establishes that the
              Work in question has not been performed in strict compliance with
              this Contract, in which case Contractor shall bear the cost of
              such test), but any delay caused by such process shall be a Force
              Majeure

                                                                         Page 20
<PAGE>

    event except where any such test establishes that the Work or portion
    thereof that is subject to such test has not been performed in strict
    compliance with this Contract. To the extent Acceptance Testing criteria
    have not been established with respect to a given portion of the System as
    of the date of this Contract, the Parties agree to cooperate in promptly
    establishing appropriate criteria as is reasonable under the circumstances.

2.  Until the Date of Final Acceptance of the System, the Purchaser agrees to
    allow Contractor reasonable access to all Segments of the System, subject to
    the terms of the Permits and Landing Licenses and provided that such access
    does not unduly interfere with service of the System.

3.  The Purchaser (together with the Independent Engineer) shall issue a
    Certificate of Commercial Acceptance if the provisions of Sub-Article
    9(D)(1) are satisfied.

4.  Once a Segment or the System is Ready for Provisional Acceptance, the
    Purchaser shall issue a Certificate of Provisional Acceptance (subject to
    the approval of the Independent Engineer), provided, that it is within the
    Purchaser's sole discretion as to whether to accept a Segment instead of the
    System.

5.  Once the System is Ready for Final Acceptance, the Purchaser (subject to the
    approval of the Independent Engineer) shall issue a Certificate of Final
    Acceptance.

6.  The Purchaser (or the Independent Engineer) shall not unreasonably withhold
    or delay issuance of a Certificate of Commercial Acceptance, a Certificate
    of Provisional Acceptance or a Certificate of Final Acceptance, as
    applicable.

7.  The Contractor agrees that, except with respect to Segment 6, the Date of
    Provisional Acceptance of the System or Date of Commercial Acceptance of the
    System will occur by December 30, 2000 (as such date may be extended under
    Article 6 (Contract Variations), Article 17 (Force Majeure) or otherwise
    under this Contract or by written agreement of the Parties (the "Scheduled
                                                                     ---------
    RFS Date")). The Contractor agrees that, with respect to Segment 6, the Date
    --------
    of Provisional Acceptance or Date of Commercial Acceptance will occur by
    February 16, 2001 (as such date may be extended under Article 6 (Contract
    Variations)) (the "Segment 6 Scheduled RFS Date"). The Contractor further
                       ----------------------------
    agrees that, with respect to Segments 4 and 5, the Date of Provisional
    Acceptance or Date of Commercial Acceptance will occur by September 30, 2000
    (as such date may be extended under Article 6 (Contract Variations)) (the
    "Segment 4/5 Scheduled RFS Date").
     ------------------------------

8.  The Date of Commercial Acceptance, Date of Provisional Acceptance and Date
    of Final Acceptance, as the case may be, shall be deemed to have

                                                                         Page 21
<PAGE>

          occurred with respect to a Segment or the System, as applicable, if a
          Certificate of Commercial Acceptance, a Certificate of Provisional
          Acceptance or a Certificate of Final Acceptance, as applicable, is
          issued with respect thereto.

B. Notice of Acceptance or Rejection

     1.   Within thirty (30) days of receipt by Purchaser and the Independent
          Engineer of the Commissioning Report, the Purchaser (subject to
          confirmation by the Independent Engineer) must issue notification to
          the Contractor of the following:

          (a)  issuance of a Certificate of Provisional Acceptance in accordance
               with Sub-Article 9(C); or

          (b)  rejection of a Certificate of Provisional Acceptance, but instead
               issuance of a Certificate of Commercial Acceptance in accordance
               with Sub-Article 9(D) below; or

          (c)  rejection of the Segment or the System in its existing condition
               and issuance of neither a Certificate of Provisional Acceptance
               nor a Certificate of Commercial Acceptance, with, in the case of
               the System, a written explanation of reasons for rejection (it
               being understood that acceptance of a Segment instead of the
               System is at the sole discretion of the Purchaser).

                    If the Purchaser or the Independent Engineer fails to
          respond with such notification within thirty (30) days, then the Date
          of Provisional Acceptance of the Segment (subject to Purchaser's
          written consent) or the System shall be deemed to be the date such
          Commissioning Report was received by the Purchaser.

     2.   On receipt of a notice from the Purchaser pursuant to Sub-Articles
          9(B)(1)(b) or (c) above, the Contractor shall be entitled to address
          any disputes and explain any discrepancies to the Purchaser regarding
          the results of the Acceptance Testing. Unless Purchaser, for good
          cause, rejects such explanation, it shall issue a new notice pursuant
          to Sub-Article 9(B)(1) above, which shall be deemed to have been
          issued on the date of the original notice.

     3.   In case of rejection, and if the explanation by the Contractor as
          referred to in Sub-Article 9(B)(2) above is not accepted, for good
          cause, by the Purchaser, the Contractor shall, at Contractor's
          expense, carry out the necessary corrective actions and will effect a
          new series of Acceptance Testing ("Retesting"). After receipt by
                                             ---------
          Purchaser and the Independent Engineer of the new Commissioning
          Report describing the results of Retesting, the

                                                                         Page 22
<PAGE>

          Purchaser will be granted a new period of thirty (30) days to analyze
          the new Commissioning Report according to the provisions of Sub-
          Article 9(B)(1) and any new notice of the Purchaser shall apply from
          the date the Purchaser receives such new Commissioning Report.

C. Provisional Acceptance

     1.   The Certificate of Provisional Acceptance may have annexed to it a
          list of all outstanding Work to be completed and deficiencies to be
          corrected by the Contractor in accordance with this Contract. The
          Contractor shall, at its expense and as soon as reasonably
          practicable, correct such deficiencies and complete the Work indicated
          on all such listed items so as to comply with the requirements of this
          Contract, provided that the Purchaser allows Contractor the necessary
          access to the Segment(s) as the Contractor reasonably needs and as
          allowed under the Permits and Landing Licenses to correct such
          deficiencies and complete the Work. The Contractor shall give the
          Purchaser reasonable notice of its requirement for such access.
          Notwithstanding the above, provided that Contractor has been allowed
          access to the Segment(s) as required in Sub-Article 9(A)(2), the
          Contractor shall continue to carry the risk of loss for any deficient
          Supply and Work until such deficiency is no longer outstanding.

D. Commercial Acceptance

     1.   A Certificate of Commercial Acceptance shall be issued by Purchaser
          and provided the Contractor accepts, with respect to a Segment or the
          System if the results of the Acceptance Testing demonstrate that such
          Segment or the System does not justify the issuance of a Certificate
          of Provisional Acceptance, but nevertheless, such Segment or the
          System is Ready for Commercial Acceptance; provided, that acceptance
          of a Segment instead of the System shall be in the sole discretion of
          the Purchaser (as confirmed by the Independent Engineer).

     2.   Each Certificate of Commercial Acceptance shall have annexed to it a
          mutually agreed list of all outstanding Work to be completed and
          deficiencies to be corrected by the Contractor in accordance with this
          Contract.

     3.   The Contractor shall, at its expense and as soon as reasonably
          practicable, correct such deficiencies and complete the Work indicated
          on such list, so as to comply with the requirements of this Contract,
          provided that the Purchaser allows Contractor (to the extent Purchaser
          has the right to do so) the necessary access to the Segment(s) as the
          Contractor reasonably needs to remedy such outstanding items. The
          Contractor shall give the Purchaser reasonable notice of its
          requirement for such access. Notwithstanding the above, provided that
          Contractor has been allowed access to the Segment(s) as required in
          Sub-Article 9(A)(2), the Contractor shall continue to carry the

                                                                         Page 23
<PAGE>

          risk of loss for any deficient Supply and Work until such deficiency
          is no longer outstanding.

     4.   When the outstanding deficiencies referenced in Sub-Article 9(D)(3)
          above have been remedied and completed, and the Segment(s) is
          otherwise Ready for Provisional Acceptance in accordance with this
          Contract, the Purchaser (as confirmed by the Independent Engineer)
          will promptly issue a Certificate of Provisional Acceptance; provided,
                                                                       --------
          that acceptance of a Segment instead of the System shall be in the
          sole discretion of the Purchaser.

     5.   The issuance of a Certificate of Commercial Acceptance with respect to
          a Segment shall in no way relieve the Contractor from its obligation
          to provide a Segment conforming with the System Performance
          Requirements at the time of the issuance of a Certificate of
          Commercial Acceptance. Moreover, the issuance of a Certificate of
          Commercial Acceptance for a Segment or the System shall not be in lieu
          of the issuance of a Certificate of Provisional Acceptance for each
          Segment and the System and the Contractor shall still be required to
          achieve the Ready for Provisional Acceptance standard with respect to
          each Segment and the System.

E. Final Acceptance

     1.   Within thirty (30) days of the date of receipt by Purchaser and the
          Independent Engineer of the Final Commissioning Report, the Purchaser
          shall issue a Certificate of Final Acceptance or reject such Report.
          If the Purchaser neither issues a Certificate of Final Acceptance nor
          rejects such Report within such thirty (30) day period, then the Date
          of Final Acceptance of the System shall be deemed to be the date such
          Final Commissioning Report was received by the Purchaser.

F. Title and Risk of Loss

     1.   If the Purchaser, in its sole discretion, chooses to accept a Segment
          prior to accepting the System, then upon payment of all amounts listed
          in the Billing Schedule with respect to such Segment (other than the
          Retainage applicable to such Segment) and the issuance of a
          Certificate of Commercial Acceptance or a Certificate of Provisional
          Acceptance with respect to such Segment by the Purchaser in accordance
          with this Contract, title (free and clear of all liens other than
          those deriving through or from the Purchaser) to such Segment and all
          Supplies incorporated into and/or attached to such Segment shall pass
          to and vest in the Purchaser.

     2.   Upon (i) payment of all amounts listed in the Billing Schedule with
          respect to the System (other than the Retainage) and (ii) the issuance
          of a Certificate of Commercial Acceptance or a Certificate of
          Provisional Acceptance with respect to the System by the Purchaser in
          accordance with this Contract, title

                                                                         Page 24
<PAGE>

               (free and clear of all liens other than those deriving through or
               from the Purchaser) to the System and all Supplies attached to
               and/or incorporated into the System shall pass to and vest in the
               Purchaser.

          3.   As from the date of vesting of title in a Segment or the System,
               as applicable, the Purchaser shall, except as set forth in the
               following sentence, assume the risk of loss in respect of all
               parts of such Segment or the System, as applicable, and
               responsibility for its maintenance. As stated in Sub-Article
               9(A)(2), the Contractor will be allowed access to such Segment,
               and, so long as the Contractor has been allowed access to such
               Segment as may be required in accordance with Sub-Article
               9(A)(2), the Contractor shall continue to carry the risk of loss
               with respect to each deficient Supply and Work under Sub-Article
               9(C)(1) and/or 9(D)(2) until such deficiencies are no longer
               outstanding.

          4.   Upon passage of title to a Segment or the System, as the case may
               be, Contractor shall deliver written evidence thereof in
               substantially the form of Exhibit E hereto.


10   Warranty
     --------

     A. Except as provided in Sub-Article 49(C), Contractor represents and
warrants that the System and the Supplies shall be free from Defects and shall
otherwise comply fully with all of the terms and provisions of this Contract,
including the requirement that the System fully meet all of the System
Performance Requirements (collectively, the "Warranty") for a period commencing
                                             --------
on the first Date of Provisional Acceptance for any Segment and ending *
after the last Date of Provisional Acceptance of any Segment (hereinafter
"Warranty Period").
 ---------------

* MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL
  TREATMENT.


          1.   The Contractor shall promptly and fully cure, at its sole cost
               and expense, by repair or replacement, at its sole option, any
               breach of the Warranty if notice of such breach is provided to
               Contractor prior to the expiration of the Warranty Period,
               including any breach which may become apparent or be discovered
               due to imperfect workmanship, faulty design or faulty Supplies,
               or any act, neglect or omission on the Contractor's part, whether
               in connection with the System or to property not constituting a
               portion of the System that is damaged or harmed by such breach.

               (a)  In making such repairs, Contractor may make changes to the
                    System or substitute Supplies of later or comparable design,
                    provided the changes, modifications, or substitutions are
                    made in accordance with this Contract and, under normal and
                    proper use do not cause the System to fail to meet any of
                    the System Performance Requirements.

               (b)  The Contractor shall use reasonable efforts to minimize the
                    period of time that any Segment or the System is out of
                    service for testing and

                                                                         Page 25

                    repair. The Purchaser agrees to cooperate with the
                    Contractor to facilitate the Contractor's repair activity.

               (c)  It is understood that if there is any breach of the
                    Warranty, the Purchaser may at any time (but it shall have
                    no obligation to) dispatch the maintenance authority to
                    effect repairs and/or replacements and the Contractor shall
                    promptly reimburse the Purchaser for the cost thereof. The
                    Contractor shall be given advance notice and be entitled, at
                    its cost and expense, to have a representative on board ship
                    to observe at sea repairs and shall be given the earliest
                    possible notice of any such repair.

               (d)  In the event that the Contractor fails to commence making
                    provision for any repair and/or replacement required
                    pursuant to this Article 10 within thirty (30) days after
                    receipt of notice from Purchaser and/or fails to use all
                    reasonable efforts to minimize the period of time that any
                    Segment or the System or any portion thereof is out of
                    service for repair and/or replacement, the Purchaser may
                    effect the repair and/or replacement and the Contractor
                    shall promptly reimburse the Purchaser for the cost thereof.
                    The Contractor shall be given advance notice and be
                    entitled, at Contractor's cost and expense, to have a
                    representative on board ship to observe at sea repairs and
                    shall be given the earliest possible notice of any such
                    repair.

     Subject to Sub-Article 10(D), any repair and/or replacement by any
maintenance authority or on behalf of the Purchaser shall not in any way
diminish the Contractor's obligation with respect to the Warranty.  Moreover,
such remedy by the Purchaser shall not limit or nullify any other obligations of
the Contractor under this Contract or the Purchaser's other rights under this
Contract.  Any Supplies discovered to be Defective or faulty and recovered
during a repair pursuant to this Article 10 shall be returned to the Contractor
at its request, and at Contractor's cost and expense.

          2.   The Contractor shall, at its cost and expense, cure fully any
               breach of the Warranty and shall supply all necessary repair
               materials, including Supplies. However, the Contractor may use,
               with the written consent of the Purchaser, which shall not be
               unreasonably withheld, the materials needed to effect a repair
               from the Purchaser's available spare materials. The Contractor
               shall promptly replace (at a time mutually agreed to by the
               Parties), at its cost and expense, in kind such materials
               supplied from the Purchaser's spare materials or, at the option
               of Purchaser, reimburse Purchaser for such materials at the
               original purchase price.

          3.   The Contractor represents and warrants that, until the expiration
               of the Warranty Period, the Work will be performed in a
               workmanlike manner using materials free from Defects except when
               such materials are provided by the Purchaser (it being understood
               that all materials arranged for directly by Contractor, whether
               or not purchased in the name of Purchaser, are not

                                                                         Page 26
<PAGE>

               materials provided by the Purchaser). If any Work proves to be
               not so performed and Purchaser notifies the Contractor prior to
               the expiration of the Warranty Period, the Contractor will
               promptly correct the Defect at Contractor's cost and expense.

          4.   Any Supply or Work which replaces any Defective Supply or Work
               during the Warranty Period shall be subject to a further Warranty
               Period of two (2) years. However, the Warranty Period shall never
               exceed five (5) years from the Date of Provisional Acceptance of
               the System.

          5.   The Contractor shall be responsible for enforcing the warranties
               of all subcontractors (including vendors of Supplies) during the
               Warranty Period.

     B. The System is designed to operate in accordance with the System
Performance Requirements for a period of twenty-five (25) years from the Date of
Provisional Acceptance (whether or not any System Upgrades are done) (the
"Design Life Period"). The Contractor represents and warrants that (i) the
 ------------------
System shall be designed so that until the * of the Date of Provisional
Acceptance of the System, no Pattern of Failure shall occur, (ii) the System
shall be designed with sufficient transmission margin to be upgradeable to a
capacity of 320 Gb/s per fiber pair, and (iii) until the * of the Date of
Provisional Acceptance of the System, no design defect shall occur with respect
to the System or any portion thereof which causes or is reasonably likely to
cause the System or any portion thereof to fail to operate in accordance with
the System Performance Requirements at any time during the Design Life Period.
In the event the Contractor breaches any of the representations and warranties
referred to in this Sub-Article 10(B), Contractor shall, at its cost and
expense, promptly effect such reengineering and redesign and make such repairs
and/or replace such Supplies as may be necessary to correct such breach. The
Contractor shall bear the costs of all repairs and Supplies and of the
reengineering and redesign necessary to effect such repairs and replacements.
The Contractor represents and warrants that all Deliverable Software and

  TREATMENT.

     C. The representations and warranties provided above in Sub-Articles 10(A)
and (B) by the Contractor shall not apply to Defects or failures of performance,
to the extent resulting from damage caused by improper acts or omissions of the
Purchaser or its agents, employees or representatives or third parties (other
than the Contractor, its agents and subcontractors), or which result from
improper modifications, misuse, neglect, accident or abuse, or improper repair,
storage or maintenance by other than the Contractor or its agents or
subcontractors, or use in a manner not in accordance with the System Description
in Appendix 4.

     D. THE WARRANTY IN THIS ARTICLE 10 IS EXCLUSIVE AND IS IN LIEU OF ALL OTHER
EXPRESS AND IMPLIED WARRANTIES INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE WHICH ARE SPECIFICALLY
DISCLAIMED; PROVIDED, HOWEVER, THAT NOTHING IN THIS ARTICLE 10 IS A LIMITATION
ON ANY WARRANTY OF TITLE OR ANY OTHER REPRESENTATION AND WARRANTY EXPRESSLY SET
FORTH IN THIS CONTRACT.

                                                                         Page 27

          1.   Standard of Work and Supplies.
               -----------------------------

               (a)  The Contractor shall ensure that all Work performed
                    hereunder, all Supplies and the System (during construction
                    and when constructed), shall strictly comply with the System
                    Performance Requirements and Appendix 4 and all other
                    requirements and provisions of this Contract, including,
                    without limitation, insurance requirements and applicable
                    Laws.

                    "Defective," and the condition causing such Work or Supply
                     ---------
                    to be Defective is referred to herein as a "Defect": new and
                                                                ------
                    undamaged, good and workmanlike, free from defects at the
                    time installed and at all times through the end of the
                    Warranty Period (including any defects in condition,
                    quality, workmanship and design, and defects arising from
                    normal weather conditions and normal use provided that

               responsibility for errors or omissions, adequate design,
               performance requirements, and proper operation of any item
               required under this Contract.

          3.   Conduct of Work on Property. In clearing the land which is
               ---------------------------
               subject to any Permit or Landing License and in the performance
               of the Work, the Contractor shall comply with the terms of this
               Contract. The Contractor shall pay to the Purchaser the value of
               any harm or damages to any land which is subject to or covered by
               any Permit or Landing License caused by the Contractor or any
               subcontractor to the extent that such harm or damages are the
               result of the Contractor's (or any subcontractor's) failure to
               act as a reasonably prudent construction contractor. The
               Contractor shall pay for all harm or damages to land or property
               outside of the land subject to or covered by any Permit or
               Landing License which is caused by the Contractor or any
               subcontractor.

          4.   Safety. The Parties recognize and agree that safety is of
               ------
               paramount importance in the performance of the Work and that the
               Contractor is fully responsible for ensuring that the Work is
               performed in a safe manner and shall take all reasonable actions
               and precautions that are necessary or advisable to ensure safety
               and to avoid accidents, injuries and property damage, including
               the use of adequate protective devices, warning signs and
               barriers as may be required under the circumstances. The
               Contractor shall comply with and cause its employees, agents and
               subcontractors (and their respective employees and agents) to
               comply with reasonable safety procedures in performing the Work.
               Nothing in this Sub-Article 10(F)(4) shall affect the
               Contractor's status as an independent contractor.

          5.   Protection of Work. Until the commencement of the Warranty
               ------------------
               Period, the Contractor shall, at its expense, continuously
               maintain reasonable protection of the Supplies and the System
               from damage, and shall protect its employees, subcontractors,
               agents and their respective employees, the employees and property
               of the Purchaser, and property owners and others in the vicinity
               of the Work from injury or loss arising in connection with this
               Contract or the Work.


11   Contractor Support
     ------------------

     A.   For a period of * from the applicable Date of Provisional Acceptance
or Date of Commercial Acceptance of the System whichever is earlier, the
Contractor will make available to the Purchaser replacement parts and repair
service for the System as may be reasonably necessary for its operation,
maintenance or repair. Where identical parts cannot be supplied, the Contractor

* MATERIAL OMITTED AND SEPARATELY FILED UNDER AN APPLICATION FOR CONFIDENTIAL
  TREATMENT.


                                                                         Page 29
<PAGE>

shall provide fully compatible parts with characteristics equal or superior to
those originally provided by the Contractor. Such parts and services shall be
provided under commercially reasonable conditions of price and delivery.

     B.  Notwithstanding Sub-Article 11(A), if for any reason the Contractor or
Contractor's suppliers intend to cease or ceases manufacturing or having
manufactured identical or fully compatible replacement parts, the Contractor
shall give at least one year's prior written notice to the Purchaser to allow
the Purchaser to order from the Contractor any required replacement parts and
shall provide full details of the arrangements to provide equivalents.


12   Purchaser's Obligations
     -----------------------

     A.  Purchaser agrees to pay all amounts payable by it when due under this
Contract and to perform all of its other obligations under this Contract.

     B.  If any loss, damage, delay or failure of performance of the System
results from the Purchaser's failure to perform its obligations under this
Contract and results in an increase in the costs of performance or the time
required for performance of any of the Contractor's duties or obligations under
this Contract, the Contractor shall be entitled, as appropriate, to (i) an
equitable adjustment in the Contract Price, (ii) an equitable extension of time
for completion of the Work, (iii) reimbursement for all such reasonable
additional costs incurred, and (iv) to the extent necessary in light of
Purchaser's failure and the adjustments made in accordance with clauses (i),
(ii) and (iii) above, an equitable adjustment of the Work.

               1.   The Contractor shall inform the Purchaser promptly of any
                    occurrence covered under this Sub-Article 12(B), and shall
                    use reasonable efforts to minimize any such additional costs
                    or delay.

               2.   The Contractor shall promptly provide to the Purchaser a
                    written estimate of the anticipated additional costs and
                    time required to complete the Work and request relief from
                    contractual obligations or duties, as appropriate. Purchaser
                    shall, upon notification, make advance payment to Contractor
                    for the reasonable estimated amount of anticipated
                    additional costs; provided that Purchaser may deposit such
                                      --------
                    amount into the Dispute Account and Sub-Article 5(C)(5)
                    shall apply. Contractor shall, without limiting Purchaser's
                    obligations in the foregoing sentence, discuss such costs
                    with Purchaser upon Purchaser's request.

               3.   As soon as reasonably practicable after the actual costs
                    become known to the Contractor, the Contractor shall provide
                    a statement of such actual costs to the Purchaser.

               4.   If the estimated amount is greater than the amount of actual
                    costs, then the Contractor shall promptly reimburse the
                    Purchaser. If the amount of actual costs incurred is greater
                    than the estimated amount, then the Purchaser shall

                                                                         Page 30
<PAGE>

                    reimburse the Contractor for any shortfall in accordance
                    with Article 5 (Terms of Payment).


13   Termination for Default
     -----------------------

     A.  Either Party may, by written notice of termination for Default,
immediately upon receipt or such later date as specified in the notice,
terminate the whole or any part of this Contract in any one of the following
circumstances (each an "Event of Default"):
                        ----------------

               1.   In the case of the Purchaser, (a) if Contractor fails to
                    comply with the terms and conditions of this Contract and,
                    if such failure occurs prior to the Date of Commercial
                    Acceptance of the System or the Date of Provisional
                    Acceptance of the System, it would be reasonable to believe
                    that the Contractor will not be able to provide (i) the
                    System (exclusive of Segment 6) which is Ready for
                    Provisional Acceptance or (ii) Segments 4 and 5 which are
                    Ready for Provisional Acceptance, in either case within one
                    hundred (100) days after the Scheduled RFS Date or the
                    Segment 4/5 Scheduled RFS Date, as the case may be; (b) if
                    Contractor fails to comply with the terms and conditions of
                    this Contract and, if such failure occurs prior to the Date
                    of Commercial Acceptance of Segment 6 or the Date of
                    Provisional Acceptance of Segment 6, it would be reasonable
                    to believe that the Contractor will not be able to provide
                    Segment 6 which is Ready for Provisional Acceptance within
                    one hundred (100) days after the Segment 6 Scheduled RFS
                    Date (provided, however, that under clauses (a) and (b) of
                    this Sub-Article 13(A)(1), the Purchaser shall provide
                    Contractor notice of such failure and a cure period which
                    shall expire on the earlier to occur of forty-five (45) days
                    after Contractor's receipt of notice of the failure and the
                    applicable Default Date and such cure period shall in no
                    event (x) affect the Purchaser's right to terminate this
                    Contract under clause (c) of this Sub-Article 13(A)(1) or
                    any other right of termination under this Contract or (y)
                    affect the Purchaser's rights to liquidated damages under
                    Article 22); or (c) the Contractor fails to cause the System
                    to be Ready for Provisional Acceptance within one hundred
                    (100) days after the Scheduled RFS Date;

               2.   If any Party defaults on any of its payment obligations and
                    does not cure such default (whether by paying money to the
                    payee or the Payment Escrow Agent) within a period of thirty
                    (30) days (or such longer period as the non-breaching Party
                    may authorize in writing) after receipt of written notice
                    demanding cure (subject to dispute provisions);

               3.   If the other Party shall commence a voluntary case or other
                    proceeding seeking liquidation, reorganization or other
                    relief with respect to itself or its debts under any
                    bankruptcy, insolvency or other similar law now or hereafter
                    in effect or seeking the appointment of a trustee, receiver,
                    liquidator, custodian or other similar official of it or any
                    substantial part of its property,

                                                                         Page 31
<PAGE>

               or shall consent to any such relief or to the appointment of or
               taking possession by any such official in an involuntary case or
               other proceeding commenced against it, or shall make a general
               assignment for the benefit of creditors, or shall fail generally
               to pay its debts as they become due, or shall take any corporate
               action to authorize any of the foregoing; or

          4.   If an involuntary case or other proceeding shall be commenced
               against the other Party seeking liquidation, reorganization or
               other relief with respect to it or its debts under any
               bankruptcy, insolvency or other similar law now or hereafter in
               effect or seeking the appointment of a trustee, receiver,
               liquidator, custodian or other similar official of it or any
               substantial part of its property, and such involuntary case or
               other proceeding shall remain undismissed and unstayed for a
               period of sixty (60) days; or an order for relief shall be
               entered against the other Party.

     B.   If this Contract is terminated by the Purchaser as provided in Sub-
Article 13(A), the Purchaser, in addition to any other rights provided in this
Article and upon payment to Contractor of all monies due and owing as set forth
in Sub-Article 13(C) below, may require the Contractor to transfer title and
deliver to the Purchaser in the manner and to the extent directed by the
Purchaser (i) any or all completed Work and/or Supplies, and/or such partially
completed Work and/or cable and materials, parts, tools, dies, jigs, fixtures,
plans, drawings, information, and contract rights (hereinafter collectively
"Manufacturing Materials"), (ii) Deliverable Software and (iii) Deliverable
 -----------------------
Technical Materials as the Contractor has had specifically produced or
specifically acquired for the performance of such part of this Contract as has
been terminated and which, if this Contract had been completed, would have been
required to be furnished to the Purchaser; and the Contractor shall, upon the
direction of the Purchaser, protect and preserve property in the Contractor's
possession in which the Purchaser has an interest.

     C.   If this Contract is terminated by Contractor as provided in Sub-
Article 13(A), the Purchaser shall pay the total of:

          1.   the cost of settling and paying claims arising out of the
               termination of Work under the contracts and orders, as provided
               in Sub-Article 14(B)(3) below which are properly chargeable to
               the terminated portion of this Contract;

          2.   the reasonable out-of-pocket costs of settlement including
               accounting, legal, clerical and other expenses necessary for the
               preparation of settlement claims and supporting data with respect
               to the terminated portion of this Contract and for termination
               and settlement of contracts thereunder, together with reasonable
               storage, transportation and other costs incurred in connection
               with the protection, preservation and disposition of property
               proper to this Contract; and

          3.   any general damages that are required by law.

                                                                         Page 32
<PAGE>

     D.  Force Majeure events pursuant to Article 17 (Force Majeure) shall not
constitute a default or provide a basis for termination under this Article.

     E.  Except as provided in Article 23 and regardless of any termination of
this Contract as provided in Sub-Article 13(A), neither Party shall be relieved
from any liability for damages or otherwise which may have been incurred by
reason of any breach of this Contract.

     F.  Without limitation to the foregoing, in the event that Purchaser
terminates this Contract pursuant to Sub-Article 13(A), the Contractor shall be
liable to Purchaser (without duplication) for the total of all costs and
expenses incurred by Purchaser in completing the Work and/or in correcting
deficiencies in the Work to the extent that the payments made to Contractor

Contract Price.


14   Termination for Convenience
     ---------------------------

     A.  The performance of Work under this Contract may be terminated by the
Purchaser in whole, or in part, at its discretion.  The Purchaser shall deliver
to the Contractor a written notice specifying the extent to which performance of
Work under this Contract is terminated, and the date upon which such termination
becomes effective (a "Notice of Termination").  Upon termination, the Purchaser
                      ---------------------

          3.  Use reasonable efforts to terminate all orders and contracts to
              the extent that they relate to the performance of Work terminated
              by the Notice of Termination;

          4.  Assign to the Purchaser, in the manner, at the time, and to the
              extent directed by the Purchaser, all of the Contractor's rights,
              title and interest under the orders and contracts so terminated;

          5.  Use reasonable efforts to settle all outstanding liabilities and

              14(B)(6) above; provided, however, that the Contractor:
                              --------  -------

                    (a)  shall not be required to extend credit to any buyer;
                    and

                    prescribed by and at a price approved by the Purchaser;

                         and provided further that the net proceeds of any such
                             -------- -------
              transfer or disposition shall be applied in reduction of any
              payments to be made by the Purchaser to the Contractor under this

              manner as the Purchaser may direct;

              possession and in which the Purchaser has acquired or may acquire
              an interest.

     C.  After such Notice of Termination, the Contractor shall submit to the
Purchaser a written termination claim. Such claim shall be submitted promptly,
but, unless otherwise extended by the Parties, in no event later than three (3)
months from the effective date of termination.

     D.  In the settlement of any such partial or total termination claim, the
Purchaser shall pay to the Contractor the total of:

          1.  all amounts invoiced in accordance with this Contract plus, for
              Work or Supplies which have been done or provided but which have
              not been invoiced, an amount calculated by reference to the prices
              set forth in the Provisioning Schedule and to the amount of such
              Work or Supplies done or provided;

          2.  the reasonable cost of settling and paying claims arising out of
              the termination of Work under the contracts and orders which are
              properly chargeable to the terminated portion of this Contract;
              and

                                                                         Page 34

              accounting, legal, clerical and other expenses necessary for the
              preparation of settlement claims and supporting data with respect
              to the terminated portion of this Contract and for termination and
              settlement of contracts thereunder, together with reasonable
              storage, transportation and other costs incurred in connection
              with the protection and disposition of property proper to this
              Contract.

     E.  In arriving at the amount due to the Contractor under this Article 14,
all unliquidated payments made to the Contractor, any liability which the
Contractor may have to the Purchaser, and the agreed price for, or the proceeds
of sale of any materials, supplies or other things acquired by the Contractor or
sold, pursuant to the provisions of this Article 14, and not otherwise recovered
by or credited to the Purchaser shall be deducted.

     F.  The Purchaser may, from time to time, under such terms and conditions
as it prescribes, approve partial payments and payments on account against costs
incurred by the Contractor in connection with the terminated portion of this
Contract. If such payments total in excess of the amount finally agreed or

all supporting books, records and documents required to be kept relating to the
terminated Work.


15   Suspension
     ----------

     A.  The Purchaser may, at its convenience, order the Contractor to suspend
all or part of the Work for such period of time as the Purchaser determines to
be appropriate. If, as a result of such suspension, the Contractor incurs
additional costs or losses in the discharge of its responsibilities under this
Contract, and where such suspension, losses or costs are not caused by the
Contractor's act or omission and could not have been reasonably prevented by the
Contractor, the Contractor shall be allowed an equitable adjustment to the
Contract Price or the Provisioning Schedule in Appendix 1 and an equitable
extension in the time required for performance.

     B.  Upon the occurrence of:

          (i)  an Event of Default by the Purchaser; or

               (ii) any transfer of this Contract prior to the Date of Final
               Acceptance of any portion of the System except in accordance with
               Article 37.

Contractor, in addition to any other rights provided in Article 13, may suspend
performance of the Work.

limiting Purchaser's obligation to make any such payment, if this Contract is
terminated by Purchaser because of a Bankruptcy Event full payment shall not be
required prior to the transfer of title), that title to Supplies, which has not
previously passed to the Purchaser, pass to the Purchaser, free and clear of all

and marine development; acts or omissions of transporters; provided that (i) a
                                                           --------
loss by Contractor of employees (other than by reasons of Force Majeure), (ii)
strikes and other labor actions involving the Contractor's own work force, (iii)
the first 5 days of Sea State 5 (unless any such day occurs during the 30 days
immediately preceding the then Scheduled RFS Date), (iv) the failure (other than
by reason of Force Majeure) of any subcontractor, supplier or transporter to
perform its obligations to Contractor (including on account of insolvency)
unless such supplies or transportation or other services are generally
unavailable in the marketplace, (v) the unavailability of any raw materials or
components, unless such raw materials or components are generally unavailable in
the marketplace or are unavailable by reason of force majeure or, (vi) any
increase in Contractor's costs shall not in and of itself constitute Force

Parties shall meet and review the circumstances surrounding the Force Majeure,
including, without limitation, the anticipated date of recommencing work.

18   Intellectual Property
     ---------------------

     A.   Ownership in Contractor; No Licenses Except Those Expressly Granted

     All right, title and interest in and to all Intellectual Property created
or developed by Contractor, under this Contract, before commencing its
performance under this Contract, is and shall remain the sole property of
Contractor.  Unless otherwise expressed in this Contract, no license is implied
or granted herein to Purchaser to any Intellectual Property by virtue of this
Contract owned or controlled by Contractor (the "Contractor Intellectual
                                                 -----------------------
Property"), nor by the transmittal or disclosure of any Contractor Intellectual
- --------
Property to Purchaser.  Any Contractor Intellectual Property disclosed,
furnished, or conveyed to Purchaser that is marked as "Proprietary" or
"Confidential" (or

                                                                         Page 37
<PAGE>

if transmitted orally is identified as being proprietary or confidential in a
subsequent writing) shall be treated in accordance with the provisions of
Article 20 (Safeguarding of Information and Technology). As used herein,
"Intellectual Property" means any information, computer or other apparatus

programs, software, specifications, drawings, designs, sketches, tools, market
research or operating data, prototypes, records, documentation, works of
authorship or other creative works, ideas, concepts, methods, inventions,
discoveries, improvements, or other business, financial and/or technical
information (whether or not protectable or registrable under any applicable
intellectual property law).

     B.   Licenses

     Contractor shall furnish to Purchaser, upon the transfer of title to any
portion of the System pursuant to this Contract, copies of all technical
information, specifications, drawings, designs, sketches, tools, operating data,
records, documentation and/or other types of engineering or technical data or
information relating to the operation, maintenance or repair of each item of
such portion of the System as delivered by Contractor (the "Deliverable
                                                            -----------
Technical Material").  Contractor grants to Purchaser a perpetual, royalty-free,
- ------------------
non-transferable (except under the circumstances specified in Sub-Article 18(G)
below) license to use and reproduce all Contractor Intellectual Property
included in or necessary to use the Deliverable Technical Materials.  This
license grant shall, in any event, be on such terms and to such an extent to
fulfill Purchaser's obligations under this Contract and shall be sufficient to
permit the Purchaser to undertake using, operating and maintaining the System
supplied by Contractor.  Further, Purchaser shall have the right to employ third
parties (under appropriate written obligations respecting confidentiality) to
assist Purchaser in fulfilling its obligations under this Contract and in using,
operating or maintaining the System.  Contractor grants to Purchaser a
perpetual, royalty-free, non-transferable (except under the circumstances
specified in Sub-Article 18(G) below) license to use and reproduce those
portions of Deliverable Technical Materials owned or controlled by third parties
(but only to the extent of any rights which may have been granted to Contractor
by such third parties).  This license grant shall be sufficient to permit the
Purchaser to undertake using, operating and maintaining the System supplied by
Contractor.  Further, Purchaser shall have the right to employ third parties
(under appropriate written obligations respecting confidentiality) to assist
Purchaser in fulfilling its obligations under this Contract and in using,
operating or maintaining the System but with no right to sublicense.  It is
expressly understood that it shall not be a violation of this license for
Purchaser, on its own behalf or through third parties (under appropriate written
obligations respecting confidentiality) specifically employed for the purpose,
to use and reproduce the Deliverable Technical Material to modify the System or
any portion thereof or connect the System or any portion thereof to other
systems, subject to the rights of third parties therein and thereto, and subject
to the limitations on Contractor's obligations as set forth in Articles 10(C)
and 19(A) concerning any such modification or interconnection.

     C.   Deliverable Software

     Contractor shall furnish to the Purchaser, upon transfer of title to any
portion of the System pursuant to this Contract, copies of all computer or other
apparatus programs and software and related documentation relating to the
operation, maintenance or repair of the computer systems of such portion of the
System, as delivered by Contractor (the "Deliverable Software"). All Deliverable
                                         --------------------
Software that is Contractor Intellectual Property shall be delivered in
executable form.  Contractor

                                                                         Page 38
<PAGE>

shall also furnish to Purchaser, from time to time during the Warranty Period,
copies of all computer or other apparatus programs and software and related
documentation that Contractor may develop to correct errors or to maintain
Deliverable Software previously furnished to Purchaser, which shall also be
treated as Deliverable Software in accordance with the terms of this provision
and subject to this Contract upon delivery thereof to Purchaser. Contractor
grants to Purchaser a perpetual, royalty-free, non-transferable (except under
the circumstances specified in Sub-Article 18(G) below) license to use and
reproduce the Deliverable Software that is Contractor Intellectual Property to
the same extent and on the same terms as the licenses granted to Purchaser under
Sub-Article 18(B) above. The license granted to Purchaser by Contractor in
Deliverable Software that is Contractor Intellectual Property or that is owned
or controlled by third parties shall be limited to use with the particular type
of computer equipment or substantially similar replacement equipment for which
such Deliverable Software was provided in the System as supplied by Contractor.

          1.   Confidentiality

                         Purchaser shall keep Deliverable Software that is
               Contractor Intellectual Property or that is owned or controlled
               by third parties confidential in accordance with Article 20
               (Safeguarding of Information and Technology) and Article 21
               (Export Control), to the extent that such Deliverable Software is
               designated as Confidential Information by its owner, and agrees
               to use commercially reasonable efforts to see that its employees,
               consultants, and agents, and other users of such software, comply
               with the provisions of this Contract. Purchaser also agrees to
               refrain from taking any steps, such as reverse assembly or
               decompilation, to derive a source code equivalent of any
               Deliverable Software, provided that Contractor does not go
               insolvent or bankrupt to thereby trigger a software escrow event
               in accordance with Article 18(H). In the case of insolvency or
               bankruptcy of Contractor, Purchaser shall limit any derivation of
               a source code equivalent to that portion of the Deliverable
               Software that is Contractor Intellectual Property. Purchaser
               shall not under any circumstances take any steps to derive a
               source code equivalent from that portion of the Deliverable
               Software comprising commercial, off-the-shelf software developed
               or provided by third parties.

          2.   Backup Copies

                         Purchaser may make and retain archive copies in
               executable form of Deliverable Software. Any copy thereof will
               contain the same copyright notice and proprietary markings as are
               on the original software and shall be subject to the same
               restrictions as the originals.

          3.   Termination of Software Licenses

                         In the event of (i) use by Purchaser of Deliverable
               Software in a manner other than as permitted in Sub-Article 18(C)
               or (ii) any other material breach of this Article 18 by Purchaser
               that, in either event, is not

                                                                         Page 39
<PAGE>

               cured within sixty (60) days from receipt by Purchaser of written
               notice of such impermissible use or breach, Contractor, at its
               option, may terminate the rights granted to Purchaser pursuant to
               this Article, which termination shall take effect no sooner than
               sixty (60) days following receipt by Purchaser of a subsequent
               written notice of termination. Upon termination, Purchaser shall
               either return or destroy, at Contractor's option, all copies of
               Deliverable Software furnished to Purchaser under this Contract.

          4.   Indemnification

                         In the event of (i) use by Purchaser of Deliverable
               Software furnished hereunder other than as permitted in Sub-
               Article 18(C) or (ii) any other material breach of this Article
               18 by Purchaser, Purchaser shall indemnify and hold Contractor
               harmless from any and all third party claims resulting therefrom,
               whether arising from a defect in the software or otherwise.

     D.   Trademarks, Tradenames, etc.

     No rights are granted herein to either Party to use any identification
(such as, but not limited to tradenames, trademarks, service marks or symbols,
and abbreviations, contractions, or simulations thereof) owned or used by the
other Party or its affiliates to identify itself, its affiliates or any of its
products or services. Each Party agrees that it will not, without the prior
written permission of the other Party, use such identification in advertising,
publicity, packaging, labeling, or in any other manner to identify itself or any
of its products, services, or organizations, or represent directly or indirectly
that any product, service, or organization is a product, service, or
organization of the other Party or its affiliates, or that any product or
service of a Party is made in accordance with or utilizes any Intellectual
Property belonging to the other Party or its affiliates.

     E.   DISCLAIMER, LIMITATION OF LIABILITY

     CONTRACTOR REPRESENTS THAT ANY INFORMATION OR INTELLECTUAL PROPERTY
FURNISHED IN CONNECTION WITH THIS CONTRACT SHALL BE TRUE AND ACCURATE TO THE
BEST OF ITS KNOWLEDGE AND BELIEF, BUT CONTRACTOR SHALL NOT BE HELD TO ANY
LIABILITY FOR UNINTENTIONAL ERRORS OR OMISSIONS THEREIN.

     F.   Representations and Warranties

     Contractor represents and warrants, to the best of its knowledge at the
time of delivery, (i) that the Deliverable Technical Materials and Deliverable
Software to be furnished by Contractor under this Contract will not infringe any
rights in Intellectual Property belonging to any third party, (ii) that
Contractor has all necessary rights to furnish such Deliverable Technical
Materials and Deliverable Software to Purchaser for use by Purchaser in
accordance with the terms of this Contract, and (iii) that Purchaser's use of
such Deliverable Technical Materials and Deliverable Software for the purposes
contemplated in this Contract will not, by itself, cause Purchaser to incur

                                                                         Page 40
<PAGE>

any liability to any third party with respect to Purchaser's use thereof in
accordance with the provisions of this Contract.

     G.   Transferability

     Except as otherwise provided in Sub-Article 37(A), (B) and (D), the
licenses granted to Purchaser by Contractor in the Deliverable Technical
Materials and Deliverable Software are personal and non-transferable, except
that Purchaser may assign or transfer such licenses to (1) an affiliated entity
under common control with the Purchaser or (2) to any entity succeeding to
Purchaser's entire interest in the System as a result of reorganization or
restructuring of the Purchaser or in the event of a change of control of the
Purchaser.

     H.   Deliverable Software Escrow

     Within sixty (60) days of the Date of Provisional Acceptance or Commercial
Acceptance of any portion of the System, the Parties shall enter into a Software
Escrow Agreement, the principals of which are outlined hereunder, with a
software escrow service, following which Contractor shall deliver copies of
source code and related documentation for that portion of Deliverable Software
that is Contractor Intellectual Property (but not that portion of Deliverable
Software comprising commercial, off-the-shelf software, or software developed or
provided by third parties) to a third party commercial software escrow service,
and from time to time as it becomes available, copies of source code for
updates, maintenance releases, or other new versions of the Deliverable Software
that is Contractor Intellectual Property relating to the operation, maintenance,
or repair of the computer systems of any portion of the System as delivered by
Contractor during the System's twenty-five (25) year Design Life Period.

     A detailed listing of commercial, off-the-shelf software, or software
developed or provided by third parties, to be included in the Deliverable
Software shall be delivered by Contractor to Purchaser within sixty (60) days of
the Date of Provisional Acceptance of any portion of the System.

     The escrow service shall be authorized by Contractor to release the
escrowed software to Purchaser within five (5) business days after the receipt
of notice by Purchaser (which notice Purchaser shall not deliver unless a
Bankruptcy Event shall have occurred in respect to either ASN or ASNI, or either
ASN or ASNI is no longer engaged in the business of operating or maintaining
systems comparable to the System) that a Bankruptcy Event has occurred or that
the Contractor is no longer in the business of operating or maintaining systems
comparable to the System.

19   Infringement
     ------------

     A.   The Contractor agrees to defend or settle at its own expense all suits
for infringement of any patent, copyright, trademark or other form of
intellectual property right in any country of the world, for the use and
operation of the System as supplied by Contractor and for any component part
thereof or Supply used therein (or the manufacture of any Supply or the normal
use thereof) provided by the Contractor or on its behalf pursuant to this
Contract and will hold the Purchaser

                                                                         Page 41
<PAGE>

harmless from all expense of defending any such suit and all payments for final
judgment assessed on account of such infringement, except such infringement or
claim arising from:

               1.   The Contractor's adherence to the Purchaser's directions in
                    the design and configuration of the System or to Supplies of
                    the Purchaser's selection; or

               2.   Such Supplies furnished to the Contractor by the Purchaser,
                    other than in each case, items of the Contractor's design or
                    selection or the same as any of the Contractor's commercial
                    merchandise or in processes or machines of the Contractor's
                    design or selection used in the manufacture of such standard
                    products or parts; or

               3.   Use of the System or the Supplies furnished by Contractor
                    other than for the purposes indicated in, or reasonably to
                    be inferred from, this Contract or in conjunction with other
                    products; or

               4.   Modification of the System or the Supplies furnished by the
                    Contractor, or connection of the System to another system by
                    any person or entity other than Contractor, without prior
                    expressed written approval by Contractor, which approval
                    shall not be unreasonably withheld.

     B.   The Purchaser will, at its own expense, defend all suits against the
Contractor for an excepted infringement as referred to in Sub-Article 19(A) and
hold the Contractor harmless from all expense of defending any such suit and
from all payments by final judgment assessed against the Contractor on account
of such excepted infringement.

     C.   The Contractor and the Purchaser agree to give each other prompt
written notice of claims and suits for infringement, full opportunity and
authority to assume the sole defense, including appeals and, upon request and at
its own expense, the other agrees to furnish all information and assistance
available to it for such defense.

     D.   If all or any portion of the System or any Supply provided by the
Contractor or on its behalf is held to constitute an infringement (excluding
excepted infringements specified in Sub-Article 19(A)) and is subject to an
injunction restraining its use or any order providing for its delivery up to or
destruction, or if in respect of any such claim of infringement the Contractor
deems it advisable to do so, the Contractor shall at its own expense either:

               1.   Procure, at the Contractor's cost and expense, for the
                    Purchaser the right to retain and continue to use the
                    System, the affected portion thereof, or any such Supply
                    without interruption for the Purchaser;

               2.   Replace or modify, at the Contractor's cost and expense, the
                    System, the affected portion thereof, or any Supply so that
                    it becomes non-infringing while continuing to meet the
                    System Performance Requirements; or

                                                                         Page 42
<PAGE>

               3.   If the remedies specified in Sub-Articles 19(D)(1) and
                    19(D)(2) are not feasible, refund to the Purchaser the full
                    purchase price paid for the System, the affected portion
                    thereof, or any Supply found to be infringing.

     E.   In no event shall the Purchaser make any admission or settle any claim
in relation with any claim for infringement without Contractor's consent.

     A.   In performance of this Contract, it may be mutually advantageous to
the Parties hereto to share certain specifications, designs, plans, drawings,
software, market research or operating data, prototypes, or other business,
financial, and or/technical information related to products, services, or
systems which are proprietary to the disclosing Party or its affiliates (and in
the case of Contractor, Contractor's parent company) (together with this
Contract and related documents, "Information"). The Parties recognize and agree
                                 -----------
that Information includes information that was supplied in contemplation hereof
prior to execution of this Contract, and further agree that Information includes

     B.   Unless such Information was previously known to the Party receiving
such Information free of any obligation to keep it confidential, or such
Information has been or is subsequently made public through other than
unauthorized disclosure by the receiving Party or is independently developed by
the receiving Party (as documented by the records of the receiving Party), it
shall be kept confidential by the Party receiving such Information, shall be
used only in the performance of this Contract, and may not be used for any other
purposes except upon such terms as may be agreed upon in writing by the Party
owning such Information. The receiving Party may disclose such Information to
other persons, upon the furnishing Party's prior written authorization, but
solely to perform acts which this Article expressly authorizes the receiving
Party to perform itself and further provided such other person agrees in writing
(a copy of which writing will be provided to the furnishing Party at its
request) to the same conditions respecting disclosure and use of Information
contained in this Article and to any other reasonable conditions requested by
the furnishing Party. Nothing herein shall prevent a Party from disclosing
Information (a) upon the order of any court or administrative agency, (b) upon
the request or demand of, or pursuant to any regulation of, any regulatory
agency or authority, (c) to the extent reasonably required in connection with
the exercise of any remedy hereunder and (d) to a Party's legal counsel or
independent auditors.

               3.   The limits specified herein are minimum requirements and
                    shall not be construed in any way as limits of liability or
                    as constituting acceptance by Purchaser (or its lenders) of
                    such responsibility for financial liabilities in excess of
                    such limits. The Contractor shall bear all deductibles
                    applicable to any insurance.

               4.   If it is judicially determined that the monetary limits of

                    assumed under the Terms and Conditions of this Contact which
                    the Contractor agrees will be supported either by available
                    liability insurance or voluntarily self-insured, in part or
                    whole, exceeds the maximum limits permitted under applicable
                    law, it is agreed that said insurance requirements or

                    maximum monetary limits permitted under such law.

               5.   Contractor shall take reasonable steps to provide that any
                    sub-contractor engaged by it has in effect or will effect
                    Employer's Liability, Workmen's Compensation, Hull and
                    Machinery and Protection and Indemnity insurances and any
                    other insurances required by law, together with such other
                    insurances as the Contractor may consider necessary.

               6.   If the Contractor fails to effect or keep in force any of
                    the insurances required under this Contract, Purchaser (or
                    its lenders on Purchaser's behalf) may effect and keep in
                    force any such insurances and pay such premiums as may be
                    necessary for that purpose and from time to time deduct the
                    amount so paid by Purchaser from any money due or which may
                    become due to the Contractor hereunder or recover the same
                    as a debt due from the Contractor, provided that Purchaser
                    is not in Default.

               7.   Each Party shall give the other prompt notification of any
                    claim with respect to any of the insurances to be provided
                    hereunder, accompanied by full details giving rise to such
                    claim. Each Party shall afford the other all such assistance
                    as may be required for the preparation and negotiation of
                    insurance claims.

               8.   Contractor shall report to Purchaser as soon as practicable
                    all accidents or occurrences resulting in injuries to
                    Contractor's employees or third parties,

                                                                         Page 49

                    during the course of services for Purchaser by Contractor.

     C.   The Contractor may organize such levels of deductibles, excesses and
self-insurance as it considers appropriate and which are within prudent industry
standards.

     D.   The insurance requirements of this Article 27 will remain in place
with respect to each Segment, and will not in any way be diminished or reduced
until the transfer of title and risk of loss shall have passed to Purchaser of
such Segment, even in the event of the sale of substantially all the assets of
the Contractor by way of a merger, consolidation or sale of assets.

All other travel and accommodation costs for the Purchaser or its QA
Representatives shall be for the account of the Purchaser.

     C.   Any right of access shall not be construed as creating any obligation
requiring the Contractor or its subcontractors to disclose trade secrets or
proprietary information. Further, such right of access may be conditioned on the
execution of a confidentiality and non-disclosure agreement and/or subject to
routine building or security rules, regulations or procedures.

     D.   Any exercise of any right of the Purchaser hereunder to inspect,
audit, visit or to observe any part of the Work shall not be construed as
limiting any obligation of Contractor hereunder, including without limitation,
under Articles 1 and 10 hereof. Moreover, and notwithstanding anything to the
contrary in this Contract, the Purchaser's right to inspect and reject Work or
Supplies shall not obligate the Purchaser to conduct such inspections. Neither
exercise by the Purchaser of such right, nor any failure on the part of the
Purchaser to discover or reject any Defective Work or Supply (or payment for or
use by the Purchaser of any Defective Work or Supply) shall be construed to
imply an acceptance of such Defective Work or Supply, or a waiver of either such
Defect or of Contractor's obligations or the Purchaser's rights under this
Contract or applicable Law.

     E.   Contractor will have access to the System as necessary to accomplish
its responsibilities under this Contract and in order to make repairs.
Contractor will provide reasonable notice of its need for access and will take
reasonable steps to minimize disruptions to the operation of the System.

     F.   Contractor shall give the Purchaser and the Independent Engineer
reasonable prior written notice of each project management review meeting with
respect to the status of the construction and/or installation of the System, and
Purchaser's representatives and the Independent Engineer shall at their cost be
permitted to attend and participate in such meetings.

     G.   Notwithstanding anything to the contrary in this Article 29, with
respect to Work performed on a cost-plus basis only, Purchaser shall have the
right to inspect, during normal business hours, all of the Contractor's
property, books, and records to perform a financial audit as to such Work, such
audit to be performed by an independent auditor chosen by the Purchaser. The
Contractor shall retain all pertinent records until three years after the
expiration of the Warranty Period. The Purchaser's auditors may copy any
documents that can be properly audited hereunder, and the Purchaser agrees that
any such copies will be used only for the Purchaser's purposes hereunder.
Contractor shall use its best endeavors to provide the Purchaser with identical
audit rights in any subcontract made by the Contractor for Work performed on a
cost-plus basis hereunder.

30   Quality Assurance
     -----------------

     All Supplies provided under this Contract shall be inspected and tested, at
the cost and expense of Contractor, by representatives designated by the
Contractor to the extent reasonably practical to assure that the quality of the
Supplies is sufficient to realize the System Performance Requirements. The
inspection and test program established for such Supplies shall be consistent
with

                                                                         Page 51

seven copies of the standard documentation, one of which shall be in the

32   Training
     --------

     The Contractor will provide, as part of the Initial Contract Price, until
the Date of Final Acceptance, any and all training necessary for the operation
and maintenance of the System. Such training shall occur in the English, Spanish
or Portuguese language, as applicable and at the request of Purchaser.

33   Settlement of Disputes/Arbitration
     ----------------------------------

     A.   The Parties shall endeavor to settle amicably by mutual discussions
any disputes, differences, or claims whatsoever related to this Contract.

     B.   Failing such amicable settlement, any controversy, claim or dispute
arising under or relating to this Contract, including the existence, validity,
interpretation, performance, termination or breach thereof, shall, be finally
settled by arbitration in accordance with the International Arbitration Rules of
the American Arbitration Association ("AAA").  Unless the Parties agree to a
                                       ---
sole arbitrator, there shall be three (3) arbitrators, with each Party
appointing one arbitrator, who collectively will select a third. The language of
the arbitration shall be English.  The Arbitrator will not have authority to
award punitive damages to either Party.  Each Party shall bear its own expenses,
but the Parties shall share equally the fees and expenses of the Arbitration
Tribunal and the AAA.  This Contract shall be enforceable, and any arbitration
award shall be final, and judgment thereon may be entered in any court of
competent jurisdiction.  In any such arbitration, the decision in any prior
arbitration under this Contract shall not be deemed conclusive of the rights as
among themselves of the Parties hereunder.  The arbitration shall be held in New
York, New York, U.S.A.

     C.   THE OBLIGATIONS OF EACH PARTY IN RESPECT OF THIS CONTRACT DUE TO ANY
OTHER PARTY SHALL, NOTWITHSTANDING ANY JUDGMENT IN A CURRENCY (THE "JUDGMENT
                                                                    --------

TO REMIT TO SUCH PARTY, SUCH EXCESS.

     A.   No information relating to this Contract shall be released by either
Party to any newspaper, magazine, journal or other written, oral or visual
medium without the prior written approval of an authorized representative of the
other Party; provided that, subject to Article 20 (Safeguarding of Information

making public or private statements in the normal course of business, so long as
consistent with a mutually agreed press-release and (ii) assisting in the
obtaining of financing in accordance with Sub-Article 37(C), including the
publication of a financial tombstone.

     B.   This Contract and any non-public information (including Information),
written or oral, with respect to this Contract (collectively, "Confidential
                                                               ------------
Information"), will be kept confidential and shall not be disclosed, in whole or
- -----------
in part, to any person other than affiliates, officers, directors, employees,
agents or representatives of a Party (collectively, "Representatives") who need
                                                     ---------------
to know such Confidential Information for the purpose of negotiating, executing
and performing this Contract. Each Party agrees to inform each of its
Representatives of the non-public nature of the Confidential Information and to
direct such persons to treat such Confidential Information in accordance with
the terms of this Article. Nothing herein shall prevent a Party from disclosing
Confidential Information (a) upon the order of any court or administrative
agency, (b) upon the request or demand of, or pursuant to any regulation of, any
regulatory agency or authority, (c) to the extent reasonably required in
connection with the exercise of any remedy hereunder, (d) to a Party's legal

proposed assignee of all or part of its rights hereunder provided that such
actual or proposed assignee agrees in writing to be bound by the provisions of
this Article.

37   Assignment; Subcontractors
     --------------------------

     A.   Except as provided in this Article 37, neither Party shall assign this
Contract or any right or interest under this Contract, nor delegate any work or
obligation to be performed under this Contract ("Assignment"), without the other
                                                 ----------
Party's prior written consent which shall not be unreasonably withheld (it being
understood that it shall be deemed to be reasonable to withhold consent to the
assignment of this Contract or any rights, interest or obligations hereunder to
a competitor of Contractor or an affiliate of a competitor or uncreditworthy
party).  For purposes of this Article 37, "competitor" means a provider of
undersea cable equipment.  Nothing herein shall preclude a Party from employing
a subcontractor in carrying out its obligations under this Contract. A Party's
use of such subcontractor shall not release the Party from its obligations or
liability (including warranties) under this Contract.  If a proposed
subcontractor of major Supplies (i.e. Supplies listed on Exhibit F) is not
                                 ----
listed on Exhibit F  hereto, Contractor shall obtain written approval thereof
from Purchaser, which approval shall not be unreasonably withheld.

     B.   Each Party has the right to assign all of its rights under this
Contract or to delegate all of its duties hereunder at any time without the
other Party's consent to any successor to substantially all the assets of the
assigning Party by way of a merger, consolidation or sale or transfer of assets
provided that in the case of any assignment or delegation pursuant to this Sub-
Article 37(B) such assignee shall assume in writing all warranties,
representations and obligations of the assigning Party under this Contract. The
assigning Party shall give the other party written notice thirty (30) days prior
to the assignment; provided, however, the assigning Party shall remain liable
for all of its obligations under this Contract as if the assignment had not
occurred. Any assignment or transfer by the assigning Party not expressly
permitted by Sub-Article 37(B) shall be of no force and effect.

     C.   The Parties acknowledge that Purchaser may finance construction of the
System and that in connection therewith the financing parties will require that
such financing be secured by certain assets of Purchaser (including but not
limited to this Contract).

               1.   Contractor agrees to deliver within fifteen (15) days upon
                    request, an opinion or opinions of counsel, in form and
                    substance reasonably satisfactory to the Purchaser,
                    addressed to the Purchaser and its lenders, which opinion or
                    opinions shall, without limitation, express the opinion that
                    this Contract is enforceable and the Contractor has all
                    necessary power and authority to execute this Contract and
                    perform its obligations hereunder.

               2.   Contractor shall execute and deliver to the Purchaser's
                    lenders all documents and certificates reasonably requested
                    by the Purchaser and shall cooperate with the Purchaser in
                    obtaining financing for the System to the extent reasonably
                    necessary. Without limiting the foregoing, Contractor
                    agrees, at its expense and to the extent reasonably
                    requested by the Purchaser and its lenders, (i) to execute
                    documents (A) consenting to the assignment of this

                                                                         Page 55
<PAGE>

                    Contract by way of security to the Purchaser's lenders, (B)
                    agreeing to pay all sums of money payable to the Purchaser
                    under this Contract to accounts held by or on behalf of the
                    Purchaser's lenders, (C) agreeing not to terminate this
                    Contract without providing (x) notice to the Purchaser's
                    lenders and (y) except in the case of Default by the
                    Purchaser which allows Contractor to terminate pursuant to
                    Article 13, consent of the Purchaser's lenders, (D) agreeing
                    not to amend or modify this Contract (including Contract
                    Variations under Article 6) in a manner that would
                    materially adversely affect the Purchaser, but in any event
                    result in a cost increase to the Purchaser in excess of
                    US$500,000, without the consent of the Purchaser's lenders,
                    (E) certifying that this Contract is in full force and
                    effect and that there is no default by Contractor (or, to
                    its knowledge, the Purchaser) under this Contract (or
                    describing any such default), (F) making representations to
                    the Purchaser's lenders concerning the corporate existence
                    of Contractor and its authority to enter into and perform
                    this Contract and other customary corporate representations
                    and (G) clarifying this Contract if reasonably requested by
                    the Purchaser's lenders; (ii) to provide the most recently
                    available information to the Purchaser's lenders concerning
                    the Contractor's finances; and (iii) to accompany, at the
                    Purchaser's expense, the Purchaser and the Purchaser's
                    lenders (or their representatives) on financing roadshows.

     D.   Notwithstanding anything in this Contract to the contrary, the
Purchaser shall have the following rights: the Purchaser shall, without the
consent of the Contractor, have the right from time to time, to (a) assign its
rights and delegate its duties under this Contract to any person or entity and
(b) to sell, transfer or otherwise dispose of its interest in the System or any
portion thereof without in any way affecting its rights or Contractor's
obligations under this Contract; PROVIDED, HOWEVER, that (i) in the case of an
assignment of the Purchaser's rights or a delegation of the Purchaser's duties
to an affiliate of the Purchaser prior to the earlier to occur of the Date of
Provisional Acceptance or the Date of Commercial Acceptance with respect to a
Segment (such earlier date is hereinafter referred to as the "Acceptance Date"),
                                                              ---------------
the Purchaser shall remain liable for all of its obligations under this Contract
with respect to such Segment until the Acceptance Date and (ii) no assignment of
the Purchaser's rights under this Contract with respect to a Segment shall be
permitted (other than to an affiliate of the Purchaser or as contemplated by
Sub-Article 37(C)) prior to the Acceptance Date with respect to such Segment
unless Contractor consents to such assignment, which consent shall not be
withheld unreasonably.

38   Relationship of the Parties
     ---------------------------

     All work performed by a Party under this Contract shall be performed as an
independent contractor and not as an agent of the other and no persons furnished

shall be responsible for its employees' compliance with all Laws while
performing under this Contract. This Contract shall not form a joint venture or
partnership between the Parties.

                                                                         Page 56

their respective successors and permitted assigns.

40   Article Captions
     ----------------

     The captions of the Articles do not form part of this Contract and shall
not have any effect on the interpretation thereof.

41   Severability
     ------------

     If any of the provisions of this Contract shall be invalid or
unenforceable, such invalidity or unenforceability shall not invalidate or
render unenforceable the entire Contract, but rather the entire Contract shall
be construed as if not containing the particular invalid or unenforceable
provision or provisions and the rights and obligations of the Contractor and the
Purchaser shall be construed and enforced accordingly. In the event such invalid
or unenforceable provision is an essential and material element of this
Contract, the Parties shall promptly negotiate a replacement provision.

42   Prime Contractor; Joint and Several Liability of the Contractor; Guarantors
     ---------------------------------------------------------------------------

     A.   The Contractor hereby designates ASN as the Prime Contractor to be
responsible for the coordination and monitoring of the Work and administration
of this Contract.  The Prime Contractor shall act as principal point of contact
between Purchaser and Contractor, although Purchaser may, at its option,
communicate with ASNI.  Any notice given to or by, any amendment or Contract
Variation executed and delivered, any consent, waiver or approval given to or
by, or any other action taken by, the Prime Contractor shall be deemed to be the
joint action of each of the parties constituting the Contractor, and Purchaser
shall be entitled to rely thereon.

     B.   ASN and ASNI shall each be jointly and severally liable to Purchaser
for payment and performance of all of the obligations and liabilities of the
Contractor whatsoever under this Contract. Each of ASN and ASNI shall, by
itself, be deemed fully liable to Purchaser for the payment and performance of
all the obligations and liabilities of the Contractor hereunder, including all
obligations and liabilities arising as a result of (i) a failure by the other
party constituting the Contractor to pay and perform its obligations and
liabilities hereunder, (ii) any breach of warranty by such other party or (iii)
any act or omission by such other party which causes a Default hereunder.
Purchaser may seek to enforce all of the obligations and liabilities of
Contractor hereunder, or seek remedies with respect thereto, against both of, or
either one of, the parties constituting the Contractor without seeking
enforcement or remedies against the other such party. Neither party constituting
the Contractor shall have the right to raise as a defense against any claim
brought by Purchaser, the allegation that such claim was caused by the fault of
the other party constituting the Contractor.

                                                                         Page 57

44   Non-Waiver
     ----------

     A waiver of any of the terms or conditions of this Contract, or the failure
of either Party strictly to enforce any such term or condition, on one or more
occasions shall not be construed as a waiver of the same or of any other term or
condition of this Contract on any other occasion.

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

     This Contract has been executed in the English language and English will be
the controlling language for interpretation of this Contract.  As used in this

               (b)  Contractor has full power and authority to execute this
                    Contract and to carry out its obligations under this
                    Contract. Its execution and performance of this Contract and
                    the consummation of the

                                                                         Page 58
<PAGE>

                    transactions contemplated by this Contract have been duly
                    authorized by all requisite corporate action on its part.
                    This Contract constitutes a valid and legally binding
                    obligation of Contractor, enforceable against it in
                    accordance with its terms, except as may be limited by

                    this Contract in its name and on its behalf, and that
                    authority has not been limited or revoked.

               (c)  Contractor's execution and performance of this Contract and
                    the transactions contemplated hereby do not constitute a
                    breach of any term or provision of, or a default under, (A)
                    any contract or agreement to which it or any of its
                    affiliates is a party or by which it or any of its
                    affiliates or its or their property is bound, (B) its
                    organizational documents or (C) any laws, regulations or
                    judicial orders having applicability to it, which breach
                    would have a material adverse affect on its ability to
                    perform its obligations hereunder.

               (d)  There is no legal proceeding pending or, to Contractor's
                    knowledge, threatened against it that could materially
                    adversely affect the validity of this Contract or its
                    ability to perform its obligations hereunder.

               (e)  It has the requisite expertise, professional qualifications,
                    skills, personnel, technology, experience and technical
                    resources to perform the Work.

               (f)  It has had a full and complete opportunity to examine this
                    Contract.

               (g)  It has made all investigations and inspections that it deems
                    necessary to perform the Work in accordance with this
                    Contract. Contractor has ascertained and relied upon its own
                    investigation of the availability and quality of laborers
                    and suppliers in each location in which all or any portion
                    of the Work is to be performed, and has investigated to its
                    satisfaction all applicable legal and regulatory
                    requirements relating thereto.

     B.   Purchaser Representations and Warranties.  Purchaser represents and
          ----------------------------------------
warrants to Contractor as follows:

               (a)  It is a duly formed and validly existing corporation under
                    the laws of its jurisdiction of incorporation. It has full
                    power and authority to own its property and to carry on its
                    business as now conducted.

                                                                         Page 59
<PAGE>

               (b)  It has full power and authority to execute this Contract and
                    to carry out its obligations under this Contract. Its
                    execution and performance of this Contract and the
                    consummation of the transactions contemplated by this
                    Contract have been duly authorized by all requisite
                    corporate action on its part. This Contract constitutes a
                    valid and legally binding obligation of Purchaser,
                    enforceable against it in accordance with its terms, except
                    as may be limited by applicable bankruptcy, insolvency,
                    reorganization, moratorium and other similar laws now or
                    hereafter in effect relating to creditors' rights generally.
                    Its representative executing this Contract has sufficient
                    authority to sign this Contract in its name and on its
                    behalf, and that authority has not been limited or revoked.

               (c)  Purchaser's execution and performance of this Contract and
                    the transactions contemplated hereby do not constitute a
                    breach of any term or provision of, or a default under, (A)
                    any contract or agreement to which it or any of its
                    affiliates is a party or by which it or any of its
                    affiliates or its or their property is bound, (B) its
                    organizational documents or (C) any laws, regulations or
                    judicial orders having applicability to it, which breach
                    would have a material adverse affect on its ability to
                    perform its obligations hereunder.

               (d)  There is no legal proceeding pending or, to Purchaser's
                    knowledge, threatened against it that could materially
                    adversely affect the validity of this Contract or its
                    ability to perform its obligations hereunder.

47   Entire Agreement
     ----------------

     This Contract supersedes all prior oral or written understanding among the
Parties and constitutes the entire agreement with respect to the subject matter
herein, including that certain Letter of Intent to Proceed issued by the
Purchaser on June 4, 1999 and signed by ASN on June 7, 1999 (the "LOI");
                                                                  ---
provided, however, that no payment is owed by the Purchaser to ASN under the LOI
as a result of the LOI being superseded by this Contract unless the Purchaser
fails to make the initial payment under Sub-Article 5(C)(2) before the
termination of this Contract by any Party.  If any Party terminates this
Contract before the initial payment is made hereunder, the Purchaser shall, in
lieu of such initial payment, be required to pay promptly the amount as
determined under paragraph 3 of the LOI.  The terms and conditions of this
Contract shall not be modified or amended except by a writing signed by
authorized representatives of the Purchaser and the Prime Contractor.

48   Optional System Upgrades
     ------------------------

     A.   Contractor hereby grants Purchaser an irrevocable option for one or
          more (as determined by Purchaser) future upgrades to the System (each
          a "System Upgrade") that may be exercised by Purchaser during the
          Upgrade Option Period. Except as otherwise provided in this Contract,
          all of the terms and conditions of this Contract (including Article
          10) shall apply to each System Upgrade.

     B.   The upgrade option period ("Upgrade Option Period") during which
          Purchaser may place orders to upgrade the System shall commence
          following the Date of Final Acceptance of the System and end *
          after the Date of Final Acceptance of the System.

     C.   The Purchaser may exercise its option for one or more System
          Upgrades at any time and from time to time during the Upgrade
          Option Period to upgrade the System by providing notice pursuant
          to Article 35.

          Each System Upgrade shall consist of an incremental increase in the
          System capacity in integral multiples of * per fiber pair around the
          System ring network, * . For particular System interfaces, a
          separate notice pursuant to Article 35 shall be provided by the
          Purchaser. Each System Upgrade shall increase the capacity of all
          Segments by equal increments for service and protection capacity
          and shall include all necessary spares, documentation and training
          attendant to such System Upgrade.

     D.   In implementing each System Upgrade, the Contractor will * any
          disruption to existing System traffic. The Contractor, upon
          receiving written authorization from Purchaser, may reroute
          traffic on a service path on the installed System to a protection
          path on the installed System in order to implement the System
          Upgrade so as not to incur traffic disruption.

     E.   The performance of the System, *, following the implementation of
          a System Upgrade, shall be consistent with the end-of-life bit error
          rate requirements as specified in the Technical Volumes. The terms
          and conditions as set forth in Article 9 govern acceptance of the
          System as upgraded by the System Upgrades.

     F.   The System Upgrades shall be provided by the Contractor at the
          prices as set forth in the Upgrade Provisioning Schedule,
          Appendix 1A and payable as set forth in the Upgrade Billing
          Schedule, Appendix 2A. Terms of payment for the Upgraded Work
          are governed by the terms and conditions as set forth in
          Article 5.

     G.   The plan of work for any System Upgrade shall be negotiated in
          good faith by the Contractor and the Purchaser; provided, however,
          that Contractor shall use reasonable efforts to ensure that the
          installation, testing and acceptance of each System Upgrade will
          occur as soon as reasonably practicable (the "Scheduled Upgrade
          Date"), but in no event later than the date which is * after the
          Purchaser gives notice pursuant to Sub-Article 48(C). The
          Purchaser will use reasonable efforts to try to forecast its
          System Upgrade capacity requirements so as to give earlier notice
          of an estimated time of upgrade to the Contractor. The Parties
          agree that where overlapping occurs because the Purchaser exercises
          its option for a System Upgrade prior to the completion of a
          previously elected System Upgrade(s), the Parties will agree in
          good faith to a mutually acceptable delivery schedule and price
          adjustment (a "Special Upgrade"). Should a need for a special upgrade
          (in addition to the foregoing) arise, the Parties will negotiate
          in good faith to meet Purchaser's needs.

                                  *

     I.   The Contractor's maximum aggregate liability, whether in tort,
          contract or otherwise, shall, for any work described in this
          Article or corresponding obligations, not exceed * of the System
          Upgrade price as set forth in the Upgrade Provisioning Schedule,
          Appendix 1A.

       CONFIDENTIAL TREATMENT.

49   Integration of BUS-1 in System
     ------------------------------

     A.   The Parties acknowledge that for the provision of the System, it will
be necessary to utilize the existing BUS-1 system. This Article governs the
utilization of the BUS-1 system. This Article shall be governed in accordance
with the terms and conditions of this Contract.

     B.   The Contractor will perform all necessary tests on BUS-1 to confirm
its capability for use in the System and to determine the number of wavelengths
by which it can be upgraded while still meeting the System Performance
Requirements.

     C.   Contractor undertakes to integrate and upgrade BUS-1 into the links
supplied by Contractor, subject to the following provisions:

               1.   Contractor has determined that BUS-1 is capable for use in
                    the System.

               2.   In its present configuration, the BUS-1 system complies with
                    performance criteria of ITU-T G.826 and interconnectivity
                    capability according to ITU-T G.957 and G.958.

               3.   Contractor is given reasonable access to BUS-1 for all
                    purposes necessary for the integration and upgrade, provided
                    that such access does not unduly interfere with service of
                    the BUS-1 system.

               4.   Purchaser will promptly repair any defects in BUS-1 (other
                    than defects caused by Contractor or its agents or
                    Subcontractors) and to the extent such defects delay the
                    Contractor in the performance of its tasks under this
                    Article 49, Contractor shall be entitled to claim extensions
                    of time under Article 17 and any additional cost arising
                    therefrom.

                                                                         Page 62
<PAGE>

               5.   With respect to BUS-1, the terms and conditions of Article
                    10 shall apply except in regard to Defects in BUS-1 not
                    caused by the Contractor (or its agents or subcontractors)
                    or any supplies not furnished by Contractor (or its agents
                    or subcontractors).

50   Optional System Extension
     -------------------------

     A.  Contractor hereby grants Purchaser an irrevocable option to change the
System configuration to include an extension to * and to one or more additional
sites in * as set forth in Appendix 1B, with exact site locations to be
determined by the Purchaser (each a "System Extension"). Except as otherwise
provided in this Contract, all of the terms and conditions of this Contract
(including Article 10) shall apply to each System Extension.

     B.  The extension option period ("Extension Option Period") during which
Purchaser may place orders to extend the System shall commence on the date
hereof and shall end on *.

     C.  Purchaser may exercise this option to extend the System during the
Extension Option Period by providing notice pursuant to Article 35.

     D.  The performance of each System Extension shall be consistent with the
end-of-life bit error rate requirements as specified in the Technical Volumes.
The terms and conditions as set forth in Article 9 govern acceptance of each
System Extension.

     E.  Each System Extension shall be provided by the Contractor * as set
forth in the Extension Provisioning Schedule, Appendix 1B and payable as set
forth in the Extension Billing Schedule, Appendix 2B. Terms of payment for the
System Extension work are governed by the terms and conditions as set forth in
Article 5.

     F.  The plan of work for any System Extension shall be negotiated in good
faith by the Contractor and the Purchaser; provided, however, that Contractor
shall use reasonable efforts to ensure that the installation, testing and
acceptance of each System Extension will occur as soon as reasonably
practicable. The Purchaser will use reasonable efforts to try to forecast its
requirements so as to give earlier notice of an estimated time for the extension
works.

     G.  The Contractor's maximum aggregate liability, whether in tort, contract
or otherwise, shall for any work or corresponding obligations described in this
article, not exceed * of the System Extension price as set forth in the
Extension Provisioning Schedule, Appendix 1B.

             accordance with the Technical Documentation and has had no
             component failure of a material nature and the Supplier has
             fulfilled its requirements under this Contract, the Purchaser shall
             issue a Certificate of Provisional Acceptance of the Cable System
             and the Cable System shall be deemed to have been provisionally
             accepted from the date indicated in the Certificate of Provisional

13.5 Certificate of Commercial Acceptance

     13.5.1  In the event that the Purchaser does not issue a Certificate of
             Provisional Acceptance because the Cable System does not fully
             conform to the requirements of the Technical Documentation, but
             nevertheless the Purchaser and the Supplier mutually agree that the
             Cable System, or any part thereof, is suitable to be put into
             commercial service, then the Purchaser shall issue to the Supplier
             a Certificate of Commercial System Acceptance. In the event that
             such a Certificate is issued, the title to the part of the Cable
             System put into commercial service shall pass to the Purchaser on
             the date of issuance of the Certificate and the responsibility
             thereto for routine maintenance shall be vested in the Purchaser.
             The Purchaser shall be entitled to commence commercial service over
             that part of the Cable System covered in the Certificate of
             Commercial System Acceptance. The Supplier is liable for any damage
             to the Cable System due to its acts or omissions and is responsible
             for all outstanding items necessary to comply with the Technical
             Documentation.

     13.5.2  The issuance of a Certificate of Commercial System Acceptance shall
             in no way relieve the Supplier from its obligation to provide a
             Cable System complying with the Technical Documentation and other
             requirements of this Contract. In particular any deterioration or
             defects in the Cable System occurring or becoming known between the
             date of issuance of that certificate and the date of issuance of a
             Certificate of Provisional System Acceptance shall be made good at
             the sole expense of the Supplier.

     13.5.3  The Supplier shall issue further results of the commissioning and
             acceptance tests after such remedial action has been taken by the
             Supplier and such results shall be considered by the Purchaser
             pursuant to Subarticle 13.3 above. If the results are satisfactory,
             and the Cable System is performing in accordance with the Technical
             Documentation and any other relevant requirements of this Contract
             then the Purchaser shall issue a Certificate of Provisional
             Acceptance, the date of which shall be when the last defect was
             repaired.

13.6 Final Acceptance

     13.6.1  The Purchaser shall in its reasonable discretion issue a
             Certificate of Final Acceptance * after Provisional Acceptance.
             Final Acceptance will be based upon the results of the Final
             Acceptance tests or, if the Purchaser decides not to perform Final
             Acceptance Tests, a Certificate of Final Acceptance shall be
             granted promptly following the two years after Provisional
             Acceptance. The issuance of the Certificate of Final Acceptance
             will not be unreasonably withheld or delayed, but in the event that
             a pattern of failure or degradation develops that is likely to
             cause the Cable System to fail to meet the Technical Documentation
             or such other performance requirements which may have been agreed
             upon between the Purchaser and the Supplier over the 25 year System
             design life. Final Acceptance may be withheld until it can be
             reasonably demonstrated that such pattern of failure or degradation
             will not continue.

contendere thereto) or (v) the failure of the Executive to carry out, or comply

     (c) Good Reason.  The Executive's employment may be terminated during
         -----------
the Employment Period by the Executive for Good Reason or without Good Reason;
provided, however, that the Executive agrees not to terminate his employment for

Good Reason unless (i) the Executive has given the Company at least 30 days'
prior written notice of his intent to terminate his employment for Good Reason,

Good Reason within such 30-day period. For purposes of this Agreement,

thereof given by the Executive; provided, however, that Good Reason may not be
                                --------  -------

compensation or benefits;

     (iii)  any failure by the Company to comply with any of the

Section 8(c);

     (v) the Company requiring the Executive to be based at any office
or location other than in Westchester County, New York or New York, New York;

     (vi) without limiting the generality of the foregoing, any material
breach by the Company or any of its subsidiaries or other Affiliates of this
Agreement.

     (d)  Notice of Termination.  Any termination by the Company for Cause
          ---------------------
or without Cause, or by the Executive for Good Reason or without Good Reason,

indicated and (iii) if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date (which date
shall not be more than 15 days after the giving of such notice).  The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

     (e)  Date of Termination.  "Date of Termination" means (i) if the
          -------------------    -------------------
Executive's employment is terminated by the Company for Cause or without Cause,
or by the Executive for Good Reason or without Good Reason, the date of receipt
of the Notice of Termination or any later date specified therein pursuant to
Section 3(d), as the case may be and (ii) if the Executive's employment is
terminated by reason of death or Disability, the date of death of the Executive
or the Disability Effective Date, as the case may be.

remained in the employ of the Company through the end of such calendar year,
based upon the number of days during such calendar year prior to the Date of
Termination (the "Accrued Bonus"); and

     (c) Cause; Other than for Good Reason.  If the Executive's employment shall

during the Employment Period, the Company shall have no further

                                       6

which have already vested shall be as provided in the Option Agreements.

     (d) If pursuant to the terms and provisions of the Company's Welfare Plans,

Company's Welfare Plans because the Executive is no longer an employee of the
Company, then the Company may fulfill its obligations under Section 4(a)(ii) or
Section 4(b), as applicable, by either providing to the Executive (or his legal
representatives), or reimbursing the Executive (or his legal representatives)
for the costs of, benefits substantially similar to the benefits provided by the
Company to its senior management under its Welfare Plans as such may from time
to time exist after the Date of Termination.

whose employment with the Company or any Affiliate thereof was terminated by the
Company or any Affiliate thereof without cause (with "cause" having the meaning

meaning similar to Good Reason)).

     (b) The Executive covenants and agrees with the Company and each Affiliate

     carry on or be engaged in or concerned with or interested in or lend money
     to, guarantee the debts or obligations of or permit his name to be used by
     a Competitive Business (as defined below).

     (c)  (i)  For the purposes of this Section 9, a "Competitive Business"
shall mean any business relating to or involving (A) the ownership (as a

                                       9
<PAGE>

principal business) and/or the construction and/or operation of any submarine
cable system which is located or is to be located between (1) Bermuda and the
United States of America, (2) Bermuda and South America, (3) the United States
of America and South America or (4) any two or more countries or continents if
the Company or any Affiliate thereof is constructing, owning and/or operating or
is to construct, own and/or operate any submarine cable system between any such
countries or continents during the Executive's employment hereunder or
(B) telecommunication services (including electronic commerce) in Bermuda.

     (ii) For purposes of this Agreement, the term "Non-Compete Period" shall
mean, in the case of:

(1)  termination of employment by the Company for Cause, two years following
     such termination;

(2)  termination of employment by the Company due to the Executive's Disability
     or without Cause, (A) the period of time following such termination and
     continuing until the expiration of the Employment Period plus (B) such
     additional period of time (if any) that the Company continues (in its sole
     discretion) to pay the Executive the Annual Base Salary in accordance with
     its customary practices for paying executive salary (but the aggregate time
     under (A) and (B) of this clause (2) shall not exceed two years);

(3)  termination of employment by the Company as a result of it providing a Non-
     Renewal Notice under Section 1, that period of time (if any) following
     termination and continuing for as long as the Company continues (in its
     sole discretion) to pay the Executive the Annual Base Salary in accordance
     with its customary practices for paying executive salary (not to exceed two
     years);

(4)  termination of employment by the Executive for Good Reason, the period of
     time following such termination and continuing until the expiration of the
     Employment Period (but in no event to exceed two years);

(5)  termination of employment by the Executive without Good Reason, two years
     following such termination; and

(6)  termination of employment by the Executive as a result of the Executive
     providing a Non-Renewal Notice under Section 1, one year from the date of
     termination plus such additional period (which additional period may not
     exceed one year) for as long as the Company in its sole discretion pays,
     during any such additional period, the Executive the Annual Base Salary

                                       10
<PAGE>

     in accordance with its customary practices for paying executive salary,
     provided that the Company shall notify the Executive of the Company's
     intention not later than 60 days prior to the expiration of the Employment
     Period if the Company intends to pay the Executive as aforesaid during such
     additional period.

     (d) The Executive covenants and agrees that until the expiration of
his covenants set out in Sections 9(a) and (b), he shall use his reasonable best
efforts to ensure that any and all current and future opportunities relating to
the telecommunications businesses and electronic commerce business of the
Company and its Affiliates and any businesses ancillary thereto shall be carried
out through the Company and its Affiliates.

     (e) The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

     (f) The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if he were to
perform in a similar capacity for a Competitive Business it would be inevitable
that he would disclose and/or use Confidential Information.

     (g) The Executive acknowledges that violations of the provisions of
Section 6 or 9 will cause immediate and irreparable harm to the Company,
entitling the Company to an injunction in or by a court of competent
jurisdiction or arbitration in addition to any other remedies the Company may
have at law or in equity, including recovery of reasonable attorneys' fees and
costs incurred by the Company in enforcing the provisions of Section 6 or 9.  In
the event that any covenant contained in Section 9 or portion of any such
covenant should be unenforceable or be declared invalid for any reason
whatsoever, such unenforceability or invalidity shall not affect the
enforceability or validity of the remaining portions of the covenants and such
unenforceable or invalid portions shall be severable from the remainder of this
Agreement.  The Executive hereby acknowledges and agrees that all restrictions
contained in this Section 9 are reasonable and valid and all defenses to the
strict enforcement thereof by the Company and are hereby waived by him.

     (h) Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's

                                       11
<PAGE>

holdings therein do not exceed five percent (5%) of the issued and outstanding
capital of the Person in question.

     (i) The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
this Agreement.

     10.  Effect of Agreement on Other Benefits.  The existence of this
          -------------------------------------
Agreement shall not prohibit or restrict the Executive's entitlement to full
participation in the executive compensation, employee benefit and other plans or
programs in which senior executives of the Company are eligible to participate.

     11.  Miscellaneous.
          -------------

     (a) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF NEW YORK WITHOUT REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS.
The captions of this Agreement are not part of the provisions hereof and shall
have no force or effect.  Whenever the terms "hereof", "hereby", "herein", or
                                              ------    ------    ------

                           -------      ---------
referring to the indicated section or paragraph of this Agreement unless the
context indicates to the contrary.  The use of the term "including" herein shall
                                                         ---------
be construed as meaning "including without limitation."  This Agreement may not

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

     (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

     (d) The Company shall obtain and maintain a director's and officer's
liability insurance policy during the term of the Executive's employment
covering the Executive on commercially reasonable terms, and the amount of
coverage shall be reasonable in relation to the Executive's position and
responsibilities hereunder; provided, however, that such coverage may be reduced
                            --------  -------
or eliminated to the extent that the Company reduces or eliminates coverage for
its directors and executives generally.

     (e) The Company may withhold from any amounts payable under this Agreement
such federal, state or local taxes as shall be required to be withheld pursuant
to any applicable law or regulation.

     (f) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

     (g) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

     (h) The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof.

                                       13

     (i) This Agreement may be executed in two or more counterparts.

     (j)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(j).

          (ii) Any and all Disputes that are not resolved through negotiation as
set forth above shall be finally settled in a binding arbitration administered
by the American Arbitration Association under its Commercial Arbitration Rules
then in effect.  The place of arbitration shall be New York, New York.  If the
parties are unable to agree on the appointment of a single arbitrator to conduct
the arbitration within 20 days after the claimant has filed its demand for
arbitration, then the arbitration shall be conducted by a panel of three
arbitrators, appointed as follows:  The Company and the Executive each shall
appoint one arbitrator, and the two arbitrators so appointed shall appoint the
third arbitrator, who shall chair the panel.  No arbitrator may be affiliated,
associated, or related to the Company, any Affiliate, employee or executive of
the Company, or the Executive in any manner whatsoever.

          (iii)  The award of the arbitrators shall be final and binding, and
judgment upon any such award may be entered by any court of competent
jurisdiction.  The arbitrators shall have no authority to award damages in
excess of compensatory damages, and each party hereby irrevocably waives any
right to recover such non-compensatory damages (including exemplary damages,
treble damages, and any other penalty or type of punitive damages) with respect
to any Dispute arising hereunder.  Each party shall bear such party's own
expenses related to any arbitration, but the parties shall share equally the
expenses of the arbitration tribunal and the AAA.

     (k) This Section 11 and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

     (l) The Executive represents and warrants to the Company that, to the
best of his personal knowledge and belief, neither the execution and  delivery
of this Agreement, his commencement of employment hereunder nor the performance
of his duties hereunder conflicts with any contractual commitment on his part
owed to any third party or violates or interferes with any rights of any third
party.

     (m) The Company shall have the right to secure, in its own name or
otherwise, and at its own expense, life, disability, accident or other insurance
covering the Executive and the Executive shall have no right, title or interest
in or to such

                                       14
<PAGE>

insurance. The Executive shall assist the Company in procuring such insurance by
submitting to reasonable examinations and signing such applications and other
instruments as may be required by the insurance carriers to which applications
is made for any such insurance.

     (n) At the request of the Company, the Executive shall execute the
necessary documents to become a party to (i) the Amended and Restated
Securityholders' Agreement dated July 14, 1999, by and among the Company and
various other parties including various shareholders of the Company (the "SHA")
                                                                          ---
and (ii) the Registration Rights Agreement referred to therein.

     (o) The Executive represents and warrants to the Company that he does
not hold any interest in any of the following New Investors (as that term is
defined in the Amended and Restated Securityholders' Agreement referred to in
the SHA):  Boston Ventures Limited Partnership V, L.P., Kelso Investment
Associates VI, L.P., KEP VI, L.L.C., Providence Equity Partners III L.P.,
Providence Equity Operating Partners III L.P., Spectrum Equity Investor III,
L.P., SEI III Entrepreneurs' Fund, L.P., Spectrum III Investment Managers' Fund,
L.P., Sandler Capital Partners IV, L.P., or Sandler Capital Partners IV FTE,
L.P., and covenants that he will not acquire an interest in the foregoing New
Investors during the Employment Period.

     IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand
and, pursuant to the authorization from the Board, the Company has caused this
Agreement to be executed in its name on its behalf, all as of the day and year
first above written.

termination of employment with the Company, except that:

         (a)  If Executive's employment with the Company terminates by reason of
     Disability (as defined in the Executive Employment Agreement effective as
     of October 1, 1999, by and between Executive and Company (the "Employment
     Agreement")), this Option shall become 100% vested and shall be exercisable
     at any time until the completion of one year after an Evaluation Event (as
     defined in Section 7 hereof).

         (b)  If Executive dies while in the employ of the Company, Executive
     shall be fully vested in this Option and Executive's estate, or the person
     who acquires this Option by will or the laws of descent and distribution or
     otherwise by reason of the death of Executive, may exercise this Option in
     full at any time until the completion of one year after an Evaluation Event
     (as defined in Section 7 hereof).

         (c)  If the Company terminates Executive's employment with the Company
     for Cause (as defined in the Employment Agreement) or if Executive
     voluntarily terminates his employment with the Company for other than Good
     Reason (as defined in the Employment Agreement), this Option shall
     terminate and cease to be exercisable in its entirety (including with
     respect to Shares that have previously vested under Section 3 hereof).

         (d)  If (i) Executive terminates his employment with the Company for
     Good Reason (as defined in the Employment Agreement), (ii) the Company
     terminates Executive's employment with the Company for other than Cause (as
     defined in the Employment Agreement), or (iii) the Company does not renew
     Executive's Employment Agreement at the termination thereof, this Option
     shall become 100% vested and shall be exercisable at any time until the
     completion of one year after an Evaluation Event (as defined in Section 7
     hereof).

     Notwithstanding the above, this Option shall not be exercisable in any
event after the expiration of ten years from the Effective Date.  The purchase
price of Shares as to which this Option is exercised shall be paid in full at
the time of exercise in cash (including check, bank draft or money order payable
to the order of the Company).  No fraction of a Share shall be issued by the
Company upon exercise of this Option; rather, Executive shall provide a cash
payment for such amount as is necessary to effect the issuance and acceptance of
only whole Shares.  Unless and until a certificate or certificates representing
such Shares shall have been issued by the Company to Executive, Executive (or
the person permitted to exercise this Option in the event of Executive's death)
shall not be or have any of the rights or privileges of a shareholder of the
Company with respect to Shares acquirable upon an exercise of this Option.

     5.  Administration. The Board of Directors of the Company (the "Board")
         --------------
shall have such powers and authorities related to the administration of this
Agreement as are consistent with

                                       2
<PAGE>

the Company's memorandum of association and bye-laws and applicable law. The
Board shall have full power and authority to take all actions and to make all
determinations required or provided for under this Agreement, and shall have
full power and authority to take all such other actions and determinations not
inconsistent with the specific terms and provisions of this Agreement that the
Board deems to be necessary or appropriate to the administration of this
Agreement. All such actions and determinations shall be by an affirmative
majority vote of the Board or by unanimous consent of the Board executed in
writing in accordance with the Company's memorandum of association and bye-laws
and applicable law. The interpretation and construction by the Board of any
provision of this Agreement shall be final and conclusive.

     The Board from time to time may appoint a Committee (the "Committee").  The
Board, in its sole discretion, may provide that the role of the Committee shall
be limited to making recommendations to the Board concerning any determinations
to be made and actions to be taken by the Board pursuant to or with respect to
this Agreement, or the Board may delegate to the Committee such powers and
authorities related to the administration and implementation of this Agreement,
as set forth in the preceding paragraph and in other applicable provisions, as
the Board shall determine, consistent with the Company's memorandum of
association and bye-laws and applicable law.  In the event that this Agreement
provides for any action to be taken by or determination to be made by the Board,
such action may be taken by or such determination may be made by the Committee
if the power and authority to do so has been delegated to the Committee by the
Board as provided for in this Section.  Unless otherwise expressly determined by
the Board, any such action or determination by the Committee shall be final,
binding and conclusive.

     6.  Status of Shares. Executive understands that at the time of the
         ----------------
execution of this Agreement the Shares to be issued upon exercise of this Option
have not been registered under the U.S. Securities Act of 1933, as amended, any
Canadian securities laws, or other applicable securities laws ("Securities
Laws"). Until the Shares acquirable upon the exercise of this Option have been
registered for issuance under Securities Laws, the Company will not issue such
Shares unless the holder of this Option provides the Company, at its request,
with a written opinion of legal counsel, who shall be satisfactory to the
Company, addressed to the Company and satisfactory in form and substance to the
Company's counsel, to the effect that the proposed issuance of such Shares to
such Option holder may be made without registration under Securities Laws. In
the event exemption from registration under Securities Laws is available upon an
exercise of this Option, Executive (or the person permitted to exercise this
Option in the event of Executive's death), if requested by the Company to do so,
will execute and deliver to the Company in writing an agreement containing such
provisions as the Company may require to assure compliance with Securities Laws.
If the Executive is an employee of the Company at the time the aforesaid opinion
is provided to the Company, the Company shall bear the legal fees incurred by
the Executive in connection with the preparation of said opinion.

     Executive agrees that the Shares which Executive may acquire by exercising
this Option shall be acquired for investment without a view to distribution,
within the meaning of Securities Laws, and shall not be sold, transferred,
assigned, pledged or hypothecated in the absence of an effective registration
statement for the Shares under Securities Laws or an applicable exemption from
the registration requirements of Securities Laws.  Executive also agrees that
the Shares which

                                       3
<PAGE>

Executive may acquire by exercising this Option will not be sold or otherwise
disposed of in any manner which would constitute a violation of any Securities
Laws.

     In addition, Executive agrees (i) that the certificates representing the
Shares purchased under this Option may bear such legend or legends as the Board
deems appropriate in order to assure compliance with Securities Laws and (ii)
that the Company may refuse to register the transfer of the Shares purchased
under this Option in the register of members of the Company if such proposed
transfer would in the opinion of counsel satisfactory to the Company constitute
a violation of any Securities Law and that the Company may give related
instructions to its transfer agent, if any, to stop registration of the transfer
of such Shares.

     7.  Additional Compensation.  If an Evaluation Event (as defined below)
         -----------------------
occurs anytime within ten years after the Effective Date and, at the time of the
Evaluation Event, (1) the Executive is an employee of the Company or (2) the
Executive is no longer employed by the Company and the employment relationship
was terminated under Section 3(a) (due to death or Disability of the Executive)
or 3(c) (due to Good Reason) of the Employment Agreement or by the Company
without Cause pursuant to Section 3(b) of the Employment Agreement; (ii) the
Investors (as defined below) have attained a Return (as defined below) on their
equity investment 9made from and after July 14, 1999) in the Company equal to
the greater of an annual compounded Return of twenty percent (20%) per year or a
total Return of seventy-two and eight-tenths percent (72-8/10%); and (iii) the
Total Value (as defined below) as of the Evaluation Event is less than
$10,000,000 (the amount by which $10,000,000 exceeds the Total Value is
hereinafter referred to as the "Shortfall Amount", then, within thirty (30) days
after Evaluation event, the Company at its discretion (but after consultation
with the Executive) shall:

         (a)  pay Executive the Shortfall Amount in cash;

         (b)  grant additional fully-vested options to Executive to purchase
     Shares, which Shares shall have a Fair Market Value (as of the Evaluation
     Event) equal to the sum of the Shortfall Amount and the aggregate option
     price of such Shares;

         (c)  grant additional fully-vested options to Executive to purchase
     Shares, which options shall have a Black-Scholes value (as of the
     Evaluation Event) equal to the Shortfall Amount;

         (d)  award additional Shares to Executive (which Shares may be subject
     to restrictions as reasonably required by the Company) which have a Fair
     Market Value (as of the Evaluation Event) equal to the Shortfall Amount; or

         (e)  compensate Executive through a combination of the alternatives set
     forth in (a), (b), (c) and (d) above, such that the aggregate compensation
     amount equals the Shortfall Amount.

     For purposes of this Section 7:

         "Evaluation Event" shall be defined as the consummation of (i) an
          ----------------
underwritten public offering of the Company's common shares or (ii) a private
sale (or series of related private

                                       4
<PAGE>

sales) of 50% or more of the common shares of the Company (or merger or other
business combination having the same effect).

      "Fair Market Value" means the value of a Share as determined by the Board
       -----------------
in its discretion, as either: (a) the closing price of the Share on the Bermuda
Stock Exchange or other established national or regional stock exchange on which
the Shares are listed or established securities market in which the Shares are
publicly traded (the highest such closing price if there is more than one such
exchange or market) on the determination date (or if there is no such reported
closing price, the Fair Market Value shall be the mean between the highest bid
and lowest asked prices or between the high and low sale prices on such trading
day) or, if no sale of Shares is reported for such trading day, on the next
preceding day on which any sale shall have been reported; or (b) the value of a
Share as determined by the Board in good faith applying appropriate valuation
principles.

     "Investors" shall be defined as the shareholders of the Company who
      ---------
invested in the Company's private placement of its common stock on July 14,
1999.

     "Return" shall be defined as the percentage increase in the implicit value
      ------
of the Investors' investment (made from and after July 14, 1999) in the Company
from July 14, 1999 to the Evaluation Event.  The implicit value of such
investment shall be calculated using the percentage of the common shares in the
Company held by the Investors (without giving affect to any shares acquired
prior to the closing of the Company's private placement of shares on July 14,
1999) times the implicit value of the Company determined by reference to the
Evaluation Event.  In making such calculation, there shall be no adjustment for
any control premium, overhang, lack of liquidity, taxes, transactions costs or
similar factors.  The implicit value of the Investors' interest in the Company
shall, however, be increased by dividends, if any, that have been paid on the
shares acquired by the Investors on or after July 14, 1999.

     "Total Value" means the sum of:  (i) the greater of (A) the gross proceeds
      -----------
(and the fair market value of all other consideration) received (on or prior to,
or in respect of, the Evaluation Event) by the Executive from the Executive's
disposition of (1) any portion of this Option and (2) Shares acquired pursuant
to any exercise of this Option or (B) the Fair Market Value (as of the
Evaluation Event) of the Shares subject to this Option as referred to in (A)(1)
and the Shares as referred to in (A)(2); (ii) the Fair Market Value (as of the
Evaluation Event) of the Shares acquired pursuant to the exercise of this Option
and held by the Executive immediately after giving effect to the Evaluation
Event (but determined without giving affect to any grant or award referred to in
7(a), (b), (c), (d) and (e) above); (iii) the Fair Market Value (as of the
Evaluation Event) of the Shares previously disposed of by the Executive by way
of gift and/or charitable contribution; (iv) the Fair Market Value (as of the
Evaluation Event) of the Shares subject to this Option (but determined without
giving effect to any grant or award referred to in 7(a), (b), (c), (d) and (e)
above); and (v) the amount (or fair market value) of dividends received by the
Executive (in respect of this Option or Shares acquired in connection therewith)
prior to or on, or in connection with, any Evaluation Event, less the sum of (i)
                                                             ----
the aggregate Option Price paid for the Shares acquired pursuant to this Option
on or prior to the Evaluation Event; and (ii) the aggregate Option Price for the
Shares referred to in (iv) above of this definition of Total Value.

                                       5
<PAGE>

     For the avoidance of doubt, after the first (if any) Evaluation Event
occurs, there shall be no further adjustment to compensation under this
Section 7.

     8.  Employment Relationship.  For purposes of this Agreement, Executive
         -----------------------
shall be considered to be in the employment of the Company as long as Executive
remains an employee of either the Company, a parent or subsidiary corporation of
the Company, or a company or a parent or subsidiary of such company assuming or
substituting a new option for this Option. Any question as to whether and when
there has been a termination of such employment, and the cause of such
termination, shall be determined pursuant to the Employment Agreement.

     9.  Transferability of Options.  This Option shall, during an Executive's
         --------------------------
lifetime, be exercisable only by the Executive, and neither this Option nor any
right hereunder shall be transferable by the Executive, by operation of law or
otherwise, other than as may be provided in this Agreement or as may be provided
by will or the laws of descent and distribution.  Except as may be provided in
this Agreement, this Option shall not be charged, mortgaged, pledged or
hypothecated (by operation of law or otherwise) or subject to execution,
attachment or similar processes.

     10.  Effect of Changes in Capitalization.
          -----------------------------------

         (a) Changes in Shares. If the number of outstanding Shares is increased
or decreased or the Shares are changed into or exchanged for a different number
or kind of shares or other securities of the Company as a result of any
recapitalization, reclassification, share split, reverse split, combination of
Shares, exchange of Shares, Share dividend or other distribution payable in
share capital, or other increase or decrease in such Shares effected without
receipt of consideration by the Company occurring after the Effective Date, the
number and kinds of Shares for which this Option is outstanding shall be
adjusted proportionately and accordingly so that the proportionate interest of
the Executive immediately following such event shall, to the extent practicable,
be the same as immediately before such event. Any such adjustment in this Option
shall not change the aggregate Option Price payable with respect to Shares that
are subject to the unexercised portion of this Option outstanding but shall
include a corresponding proportionate adjustment in the Option Price per Share.

         (b)  Reorganization in which the Company is the Surviving or Continuing
Entity and in which no Change of Control Occurs. Subject to the following
paragraph hereof, if the Company shall be the surviving or continuing entity in
any reorganization, merger, amalgamation, or consolidation of the Company with
one or more other entities, this Option shall pertain to and apply to the
securities to which a holder of the number of Shares subject to such Option
would have been entitled immediately following such reorganization, merger,
amalgamation, or consolidation, with a corresponding proportionate adjustment of
the Option Price per Share so that the aggregate Option Price thereafter shall
be the same as the aggregate Option Price of the Shares remaining subject to the
Option immediately prior to such reorganization, merger, amalgamation, or
consolidation.

         (c)  Adjustments. Adjustments under this Section 10 related to Shares
or securities of the Company shall be made by the Board, whose determination in
that respect shall be final, binding and conclusive. No fractional Shares or
other securities shall be issued pursuant to

                                       6
<PAGE>

any such adjustment, and any fractions resulting from any such adjustment shall
be eliminated in each case by rounding downward to the nearest whole Share.

         (d)  No Limitations on Company. The granting of this Option shall not
affect or limit in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations, or changes of its capital or
business structure or to merge, amalgamate, consolidate, dissolve, or liquidate,
or to sell or transfer all or any part of its business or assets.

     11.  Withholding of Tax. To the extent that the exercise of this Option
          ------------------
or the disposition of Shares acquired by exercise of this Option results in
compensation income to Executive for tax purposes, Executive shall deliver to
the Company at the time of such exercise or disposition such amount of money as
the Company may require to meet its obligation under applicable tax laws or
regulations, and, if Executive fails to do so, the Company is authorized to
withhold from any cash or Shares remuneration then or thereafter payable to
Executive any tax required to be withheld by reason of such resulting
compensation income. Upon an exercise of this Option, the Company is further
authorized in its discretion to satisfy any such withholding requirement out of
any cash or Shares distributable to Executive upon such exercise.

     12.  Binding Effect.  This Agreement shall be binding upon and inure to the
          --------------
benefit of any successors to the Company and all persons lawfully claiming under
Executive.

     13.  Governing Law.  This Agreement shall be governed by, and construed in
          -------------
accordance with, the laws of Bermuda.

          IN WITNESS WHEREOF, the Company has caused this Agreement to be duly
executed by its officer thereunto duly authorized, and Executive has executed
this Agreement, all as of the day and year first above written.

                      SUPPLEMENTAL STOCK OPTION AGREEMENT


     AGREEMENT made effective as of the 7th day of October, 1999 ("Effective
Date") between GlobeNet Communications Group Limited, a Bermuda company (the
"Company") and Jerry A. DeMartino ("Executive").

     In consideration of the mutual agreements and other matters set forth
herein, the Company and Employee hereby agree as follows:

     1.   Grant of Option.  The Company hereby irrevocably grants to Executive
          ---------------
the right and option ("Option") to purchase all or any part of an aggregate of
49,019 shares of authorized but unissued common shares of the Company, par value
U.S. $1.50 ("Shares"), on the terms and conditions set forth herein.  This
Option shall not be treated as an incentive stock option within the meaning of
section 422(b) of the U.S. Internal Revenue Code of 1986, as amended (the
"Code").

     2.   Option Price.  The purchase price of Shares purchased pursuant to the
          ------------
exercise of this Option shall be U.S. $20.40 per share ("Option Price").

     3.   Exercise of Option.  This Option may be exercised in whole or in part,
          ------------------
by written notice to the Company at its principal executive office addressed to
the attention of its General Counsel, at any time after the date of grant
hereof, but it must be exercised within three months of the Effective Date.

     This Option shall not be exercisable in any event after the expiration of
three months from the Effective Date.  The purchase price of shares as to which
this Option is exercised shall be paid in full at the time of exercise in cash
(including check, bank draft or money order payable to the order of the
Company).  No fraction of a Share shall be issued by the Company upon exercise
of this Option; rather, Executive shall provide a cash payment for such amount
as is necessary to effect the issuance and acceptance of only whole Shares.
Unless and until a certificate or certificates representing such shares shall
have been issued by the Company to Executive, Executive shall not be or have any
of the rights or privileges of a shareholder of the Company with respect to
shares acquirable upon an exercise of this Option.

     4.   Administration.  The Board of Directors of the Company (the "Board")
          --------------
shall have such powers and authorities related to the administration of this
Agreement as are consistent with the Company's memorandum of association and
bye-laws and applicable law. The Board shall have full power and authority to
take all actions and to make all determinations required or provided for under
this Agreement, and shall have full power and authority to take all such other
actions and determinations not inconsistent with the specific terms and
provisions of this Agreement that the Board deems to be necessary or appropriate
to the administration of this Agreement. All such actions and determinations
shall be by an affirmative majority vote of the Board or by unanimous consent of
the Board executed in writing in accordance with the Company's memorandum of

                                       1
<PAGE>

association and bye-laws and applicable law. The interpretation and construction
by the Board of any provision of this Agreement shall be final and conclusive.

     The Board from time to time may appoint a Committee (the "Committee").  The
Board, in its sole discretion, may provide that the role of the Committee shall
be limited to making recommendations to the Board concerning any determinations
to be made and actions to be taken by the Board pursuant to or with respect to
this Agreement, or the Board may delegate to the Committee such powers and
authorities related to the administration and implementation of this Agreement,
as set forth in the preceding paragraph and in other applicable provisions, as
the Board shall determine, consistent with the Company's memorandum of
association and bye-laws and applicable law.  In the event that this Agreement
provides for any action to be taken by or determination to be made by the Board,
such action may be taken by or such determination may be made by the Committee
if the power and authority to do so has been delegated to the Committee by the
Board as provided for in this Section.  Unless otherwise expressly determined by
the Board, any such action or determination by the Committee shall be final,
binding and conclusive.

     5.   Status of Shares.  Executive understands that at the time of the
          ----------------
execution of this Agreement the Shares to be issued upon exercise of this Option
have not been registered under the U.S. Securities Act of 1933, as amended, any
Canadian securities laws, or other applicable securities laws ("Securities
Laws"). Until the Shares acquirable upon the exercise of this Option have been
registered for issuance under Securities Laws, the Company will not issue such
Shares unless the holder of this Option provides the Company, at its request,
with a written opinion of legal counsel, who shall be satisfactory to the
Company, addressed to the Company and satisfactory in form and substance to the
Company's counsel, to the effect that the proposed issuance of such Shares to
such Option holder may be made without registration under Securities Laws. In
the event exemption from registration under Securities Laws is available upon an
exercise of this Option, Executive (or the person permitted to exercise this
Option in the event of Executive's death), if requested by the Company to do so,
will execute and deliver to the Company in writing an agreement containing such
provisions as the Company may require to assure compliance with Securities Laws.
If the Executive is an employee of the Company at the time the aforesaid opinion
is provided to the Company, the Company shall bear the legal fees incurred by
the Executive in connection with the preparation of said opinion.

     Executive agrees that the Shares which Executive may acquire by exercising
this Option shall be acquired for investment without a view to distribution,
within the meaning of Securities Laws, and shall not be sold, transferred,
assigned, pledged or hypothecated in the absence of an effective registration
statement for the Shares under Securities Laws or an applicable exemption from
the registration requirements of Securities Laws.  Executive also agrees that
the Shares which Executive may acquire by exercising this Option will not be
sold or otherwise disposed of in any manner which would constitute a violation
of any Securities Laws.

     In addition, Executive agrees (i) that the certificates representing the
Shares purchased under this Option may bear such legend or legends as the Board
deems appropriate in order to assure compliance with Securities Laws and (ii)
that the Company may refuse to register the transfer of the Shares purchased
under this Option in the register of members of the Company if such proposed
transfer would in the opinion of counsel satisfactory to the Company constitute
a

                                       2
<PAGE>

violation of any Securities Law and that the Company may give related
instructions to its transfer agent, if any, to stop registration of the transfer
of such Shares.

     6.   Employment Relationship.  For purposes of this Agreement, Executive
          -----------------------
shall be considered to be in the employment of the Company as long as Executive
remains an employee of either the Company, a parent or subsidiary corporation of
the Company, or a company or a parent or subsidiary of such company assuming or
substituting a new option for this Option.  Any question as to whether and when
there has been a termination of such employment, and the cause of such
termination, shall be determined pursuant to the Employment Agreement effective
as of October 1, 1999 by and between Executive and Company.

     7.   Transferability of Options.  This Option shall, during an Executive's
          --------------------------
lifetime, be exercisable only by the Executive, and neither this Option nor any
right hereunder shall be transferable by the Executive, by operation of law or
otherwise.  Except as may be provided in this Agreement, this Option shall not
be charged, mortgaged, pledged or hypothecated (by operation of law or
otherwise) or subject to execution, attachment or similar processes.

     8.   Effect of Changes in Capitalization.

             (a)  Changes in Shares.  If the number of outstanding Shares is
     increased or decreased or the Shares are changed into or exchanged for a
     different number or kind of shares or other securities of the Company as a
     result of any recapitalization, reclassification, share split, reverse
     split, combination of Shares, exchange of Shares, Share dividend or other
     distribution payable in share capital, or other increase or decrease in
     such Shares effected without receipt of consideration by the Company
     occurring after the Effective Date, the number and kinds of Shares for
     which this Option is outstanding shall be adjusted proportionately and
     accordingly so that the proportionate interest of the Executive immediately
     following such event shall, to the extent practicable, be the same as
     immediately before such event. Any such adjustment in this Option shall not
     change the aggregate Option Price payable with respect to Shares that are
     subject to this Option but shall include a corresponding proportionate
     adjustment in the Option Price per Share.

             (b)  Reorganization in which the Company is the Surviving or
     Continuing Entity and in which no Change of Control Occurs. Subject to the
     following paragraph hereof, if the Company shall be the surviving or
     continuing entity in any reorganization, merger, amalgamation, or
     consolidation of the Company with one or more other entities, this Option
     shall pertain to and apply to the securities to which a holder of the
     number of Shares subject to such Option would have been entitled
     immediately following such reorganization, merger, amalgamation, or
     consolidation, with a corresponding proportionate adjustment of the Option
     Price per Share so that the aggregate Option Price thereafter shall be the
     same as the aggregate Option Price of the Shares remaining subject to the
     Option immediately prior to such reorganization, merger, amalgamation, or
     consolidation.

unincorporated organization, or a government or agency or political subdivision

Employment Period by the Executive for Good Reason or without Good Reason;

Good Reason unless (i) the Executive has given the Company at least 30 days'
prior written notice of his intent to terminate his employment for Good Reason,
which notice shall specify the facts and circumstances constituting Good Reason

or benefits set forth in this Agreement;

     (iii)  any failure by the Company to comply with any of the provisions of

              ---------------------
or without Cause, or by the Executive for Good Reason or without Good Reason,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 11(b).  For purposes of this Agreement, a "Notice of
                                                                      ---------

shall not be more than 15 days after the giving of such notice).  The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

          (e) Date of Termination.  "Date of Termination" means (i) if the
              -------------------    -------------------

          (d) To the extent permitted by law, all rights worldwide with respect

exclusive property of the Company. The Executive agrees to execute, acknowledge
and deliver to the Company, at the Company's request, such further documents as
the Company finds appropriate to evidence the Company's rights in such property.

          (e) The Executive agrees to sign the Company's standard form of

          (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a

provision as may be possible and be legal, valid and enforceable.

          (e) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

          (f) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

          (g) The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof, and this Agreement supersedes any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof,
including, but not limited to, that certain Executive Employment Agreement Term
Sheet between the Company and the Executive dated the 14th day of July, 1999;
provided, however, the parties hereto shall expeditiously and in good faith
- --------  -------
negotiate a definitive agreement relating to the option by the Executive to
purchase shares of GlobeNet equal to 1% of new issuances as referred to in
footnote 1 of Schedule 1 to such term sheet and the Company shall use all
reasonable efforts to obtain necessary GlobeNet Board and applicable shareholder
approvals with respect to such option to purchase.

          (i)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(i).

               (ii) Any and all Disputes that are not resolved through
negotiation as set forth above shall be finally settled in a binding arbitration
administered by the American Arbitration Association (the "AAA") under its
                                                           ---
Commercial Arbitration Rules then in effect. The place of arbitration shall be
New York, New York. If the parties are unable to agree on the appointment of a
single arbitrator to conduct the arbitration within 20 days after the claimant
has filed its demand for arbitration, then the arbitration shall be conducted by
a panel of three arbitrators, appointed as follows: The Company and the
Executive each shall appoint one arbitrator, and the two arbitrators so
appointed shall appoint the third arbitrator, who shall chair the panel. No
arbitrator may be affiliated, associated, or related to the Company, any
Affiliate, employee or executive of the Company, or the Executive in any manner
whatsoever.

               (iii)  The award of the arbitrators shall be final and binding,
and judgment upon any such award may be entered by any court of competent
jurisdiction. The arbitrators shall have no authority to award damages in excess
of compensatory damages, and each party hereby irrevocably waives any right to
recover such non-compensatory damages (including exemplary damages, treble
damages, and any other penalty or type of punitive damages) with respect to any
Dispute arising hereunder. Each party shall bear such party's own expenses
related to any arbitration, but the parties shall share equally the expenses of
the arbitration tribunal and the AAA.

          (j) This Section 11(j) and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

          (k) The Executive represents and warrants to the Company that, to the
best of his personal knowledge and belief, neither the execution and  delivery
of this Agreement, his commencement of employment hereunder nor the performance
of his duties hereunder conflicts with any contractual commitment on his part
owed to any third party or violates or interferes with any rights of any third
party.

          (l) The Company or any of its Affiliates shall have the right to
secure, in its own name or otherwise, and at its own expense, life, disability,
accident or other insurance covering the Executive and the Executive shall have
no right, title or interest in or to such insurance. The Executive shall assist
the Company in procuring such insurance by submitting to reasonable examinations
and signing such applications and other

                                       11
<PAGE>

instruments as may be required by the insurance carriers to which applications
is made for any such insurance.

          IN WITNESS WHEREOF, the Executive has hereunto set the Executive's
hand and, pursuant to the authorization from the Board, the Company has caused
this Agreement to be executed in its name on its behalf, all as of the day and
year first above written.

                                   Exhibit B

     Attached to and made a part of that certain Executive Employment Agreement
dated as of October 7, 1999 between Michael Kedar and TeleBermuda International
(Canada) Limited to become effective as provided in Article 9 hereof.

          (a) The Executive covenants and agrees with the Company that, while he
is an employee of the Company or any Affiliate thereof and for a period of two
years thereafter he will not, without the prior written consent of the Company,
either directly or indirectly:

          (i) solicit any contractors, customers or distributors of the Company
or any Affiliate thereof or endeavor to entice away from the Company or any
Affiliate thereof any such Person or otherwise interfere with the relationship
between such Person and the Company or any Affiliate thereof for the purposes of
competing with the Company or any Affiliate thereof;

          (ii) endeavor to entice away from the Company or any Affiliate thereof
any person who is employed by the Company or any Affiliate thereof, either
directly or indirectly, or interfere in any way with the employer/employee
relations between any such employee and the Company or any Affiliate thereof; or

          (iii)  offer employment to any person who was employed by the Company
or any Affiliate at the date upon which the Executive ceases to be an employee
of the Company or any Affiliate thereof.

          (b) The Executive covenants and agrees with the Company and each
Affiliate thereof that (i) while he is an employee of the Company or any
Affiliate thereof he shall not directly or indirectly compete in any manner
against the Company or any of its Affiliates and (ii) and for a period of two
years following the date he ceases such employment for whatever reason, he will
not, directly or indirectly, in any manner whatsoever, including either
individually or in partnership or jointly or in conjunction with any other
Person, as principal, agent, shareholder, employee or in any other manner
whatsoever, carry on or be engaged in or concerned with or interested in or lend
money to, guarantee the debts or obligations of or permit his name to be used by
a Competitive Business (as defined below).

          (c) For the purposes of this Exhibit B, a "Competitive Business" shall
                                                     --------------------
mean any business relating to or involving (A) the construction, ownership
and/or operation of any submarine cable system which is located or is to be
located between (1) Bermuda and the United States of America, (2) Bermuda and
South America, (3) the United States of America and South America or (4) any two
or more countries or continents if the Company or any Affiliate thereof is
constructing, owning and/or operating or is to construct, own and/or operate any
submarine cable system between any such countries or continents during the
Executive's employment hereunder or (B) telecommunication services (including
electronic commerce) in Bermuda.

                                       14
<PAGE>

          (d) The Executive covenants and agrees that until the expiration of
his covenants set out in Sections (a) and (b) of this Exhibit B, he shall use
his reasonable best efforts to ensure that any and all current and future
opportunities relating to the telecommunications businesses and electronic
commerce business of the Company and its Affiliates and any businesses ancillary
thereto shall be carried out through the Company and its Affiliates.

          (e) The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

          (f) The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if he were to
perform in a similar capacity for a Competitive Business it would be inevitable
that he would disclose and/or use Confidential Information.

          (g) The Executive acknowledges that violations of the provisions of
Section 6 of the Agreement or the provisions of this Exhibit B will cause
immediate and irreparable harm to the Company, entitling the Company to an
injunction in or by a court of competent jurisdiction or arbitration in addition
to any other remedies the Company may have at law or in equity, including
recovery of reasonable attorneys' fees and costs incurred by the Company in
enforcing the provisions of Section 6 of the Agreement or the provisions of this
Exhibit B.  In the event that any covenant contained in the provisions of this
Exhibit B or portion of any such covenant should be unenforceable or be declared
invalid for any reason whatsoever, such unenforceability or invalidity shall not
affect the enforceability or validity of the remaining portions of the covenants
and such unenforceable or invalid portions shall be severable from the remainder
of this Agreement.  The Executive hereby acknowledges and agrees that all
restrictions contained in this Exhibit B are reasonable and valid and all
defenses to the strict enforcement thereof by the Company and are hereby waived
by him.

          (h) Nothing in this Exhibit B shall be deemed to prevent or prohibit
the Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

                                       15
<PAGE>

          (i) The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
the Agreement and this Exhibit B.

                      SUPPLEMENTAL STOCK OPTION AGREEMENT


     AGREEMENT made effective as of the 7th day of October, 1999 ("Effective
Date") between GlobeNet Communications Group Limited, a Bermuda company (the
"Company") and Michael Kedar ("Executive").

     In consideration of the mutual agreements and other matters set forth
herein, the Company and Employee hereby agree as follows:

     1.   Grant of Option. The Company hereby irrevocably grants to Executive
          ---------------
the right and option ("Option") to purchase all or any part of an aggregate of
80,000 shares of authorized but unissued common shares of the Company, par value
U.S. $1.50 ("Shares"), on the terms and conditions set forth herein. This Option
shall not be treated as an incentive stock option within the meaning of section
422(b) of the U.S. Internal Revenue Code of 1986, as amended (the "Code").

     2.   Option Price.  The purchase price of Shares purchased pursuant to the
          ------------
exercise of this Option shall be U.S. $20.40 per share ("Option Price").

     3.   Exercise of Option.  This Option may be exercised in whole or in part,
          ------------------
by written notice to the Company at its principal executive office addressed to
the attention of its General Counsel, at any time after the date of grant
hereof.

     This Option shall not be exercisable in any event after the expiration of
ten years from the Effective Date.  The purchase price of shares as to which
this Option is exercised shall be paid in full at the time of exercise in cash
(including check, bank draft or money order payable to the order of the
Company).  No fraction of a Share shall be issued by the Company upon exercise
of this Option; rather, Executive shall provide a cash payment for such amount
as is necessary to effect the issuance and acceptance of only whole Shares.
Unless and until a certificate or certificates representing such shares shall
have been issued by the Company to Executive, Executive shall not be or have any
of the rights or privileges of a shareholder of the Company with respect to
shares acquirable upon an exercise of this Option.

     4.   Administration.  The Board of Directors of the Company (the "Board")
          --------------
shall have such powers and authorities related to the administration of this
Agreement as are consistent with the Company's memorandum of association and
bye-laws and applicable law. The Board shall have full power and authority to
take all actions and to make all determinations required or provided for under
this Agreement, and shall have full power and authority to take all such other
actions and determinations not inconsistent with the specific terms and
provisions of this Agreement that the Board deems to be necessary or appropriate
to the administration of this Agreement. All such actions and determinations
shall be by an affirmative majority vote of the Board or by unanimous consent of
the Board executed in writing in accordance with the Company's memorandum of

                                       1
<PAGE>

association and bye-laws and applicable law. The interpretation and construction
by the Board of any provision of this Agreement shall be final and conclusive.

     The Board from time to time may appoint a Committee (the "Committee").  The
Board, in its sole discretion, may provide that the role of the Committee shall
be limited to making recommendations to the Board concerning any determinations
to be made and actions to be taken by the Board pursuant to or with respect to
this Agreement, or the Board may delegate to the Committee such powers and
authorities related to the administration and implementation of this Agreement,
as set forth in the preceding paragraph and in other applicable provisions, as
the Board shall determine, consistent with the Company's memorandum of
association and bye-laws and applicable law.  In the event that this Agreement
provides for any action to be taken by or determination to be made by the Board,
such action may be taken by or such determination may be made by the Committee
if the power and authority to do so has been delegated to the Committee by the
Board as provided for in this Section.  Unless otherwise expressly determined by
the Board, any such action or determination by the Committee shall be final,
binding and conclusive.

     5.   Status of Shares.  Executive understands that at the time of the
          ----------------
execution of this Agreement the Shares to be issued upon exercise of this Option
have not been registered under the U.S. Securities Act of 1933, as amended, any
Canadian securities laws, or other applicable securities laws ("Securities
Laws"). Until the Shares acquirable upon the exercise of this Option have been
registered for issuance under Securities Laws, the Company will not issue such
Shares unless the holder of this Option provides the Company, at its request,
with a written opinion of legal counsel, who shall be satisfactory to the
Company, addressed to the Company and satisfactory in form and substance to the
Company's counsel, to the effect that the proposed issuance of such Shares to
such Option holder may be made without registration under Securities Laws. In
the event exemption from registration under Securities Laws is available upon an
exercise of this Option, Executive (or the person permitted to exercise this
Option in the event of Executive's death), if requested by the Company to do so,
will execute and deliver to the Company in writing an agreement containing such
provisions as the Company may require to assure compliance with Securities Laws.
If the Executive is an employee of the Company at the time the aforesaid opinion
is provided to the Company, the Company shall bear the legal fees incurred by
the Executive in connection with the preparation of said opinion.

     Executive agrees that the Shares which Executive may acquire by exercising
this Option shall be acquired for investment without a view to distribution,
within the meaning of Securities Laws, and shall not be sold, transferred,
assigned, pledged or hypothecated in the absence of an effective registration
statement for the Shares under Securities Laws or an applicable exemption from
the registration requirements of Securities Laws.  Executive also agrees that
the Shares which Executive may acquire by exercising this Option will not be
sold or otherwise disposed of in any manner which would constitute a violation
of any Securities Laws.

     In addition, Executive agrees (i) that the certificates representing the
Shares purchased under this Option may bear such legend or legends as the Board
deems appropriate in order to assure compliance with Securities Laws and (ii)
that the Company may refuse to register the transfer of the Shares purchased
under this Option in the register of members of the Company if such proposed
transfer would in the opinion of counsel satisfactory to the Company constitute
a violation of any

                                       2
<PAGE>

Securities Law and that the Company may give related instructions to its
transfer agent, if any, to stop registration of the transfer of such Shares.

     6.   Transferability of Options.  This Option shall, during an Executive's
          --------------------------
lifetime, be exercisable only by the Executive, and neither this Option nor any
right hereunder shall be transferable by the Executive, by operation of law or
otherwise.  Except as may be provided in this Agreement, this Option shall not
be charged, mortgaged, pledged or hypothecated (by operation of law or
otherwise) or subject to execution, attachment or similar processes.

     7.   Effect of Changes in Capitalization.

              (a)  Changes in Shares.  If the number of outstanding Shares is
increased or decreased or the Shares are changed into or exchanged for a
different number or kind of shares or other securities of the Company as a
result of any recapitalization, reclassification, share split, reverse split,
combination of Shares, exchange of Shares, Share dividend or other distribution
payable in share capital, or other increase or decrease in such Shares effected
without receipt of consideration by the Company occurring after the Effective
Date, the number and kinds of Shares for which this Option is outstanding shall
be adjusted proportionately and accordingly so that the proportionate interest
of the Executive immediately following such event shall, to the extent
practicable, be the same as immediately before such event. Any such adjustment
in this Option shall not change the aggregate Option Price payable with respect
to Shares that are subject to this Option but shall include a corresponding
proportionate adjustment in the Option Price per Share.

              (b)  Reorganization in which the Company is the Surviving or
Continuing Entity and in which no Change of Control Occurs. Subject to the
following paragraph hereof, if the Company shall be the surviving or continuing
entity in any reorganization, merger, amalgamation, or consolidation of the
Company with one or more other entities, this Option shall pertain to and apply
to the securities to which a holder of the number of Shares subject to such
Option would have been entitled immediately following such reorganization,
merger, amalgamation, or consolidation, with a corresponding proportionate
adjustment of the Option Price per Share so that the aggregate Option Price
thereafter shall be the same as the aggregate Option Price of the Shares
remaining subject to the Option immediately prior to such reorganization,
merger, amalgamation, or consolidation.

              (c)  Adjustments.  Adjustments under this Section 7 related to
Shares or securities of the Company shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. No
fractional Shares or other securities shall be issued pursuant to any such
adjustment, and any fractions resulting from any such adjustment shall be
eliminated in each case by rounding downward to the nearest whole Share.

              (d)  No Limitations on Company.  The granting of this Option shall
not affect or limit in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations, or changes of its capital or
business structure or to merge, amalgamate, consolidate, dissolve, or liquidate,
or to sell or transfer all or any part of its business or assets.

     8.   Withholding of Tax.  To the extent that the exercise of this Option or
          ------------------
the disposition of Shares acquired by exercise of this Option results in
compensation income to Executive for tax purposes, Executive shall deliver to
the Company at the time of such exercise or disposition such amount of money as
the Company may require to meet its obligation under applicable tax laws or
regulations, and, if Executive fails to do so, the Company is authorized to
withhold from any cash or Shares remuneration then or thereafter payable to
Executive any tax required to be withheld by reason of such resulting
compensation income.  Upon an exercise of this Option, the Company is further
authorized in its discretion to satisfy any such withholding requirement out of
any cash or Shares distributable to Executive upon such exercise.

     9.   Binding Effect.  This Agreement shall be binding upon and inure to the
          --------------
benefit of any successors to the Company and all persons lawfully claiming under
Executive.

     10.  Governing Law.  This Agreement shall be governed by, and construed in
          -------------
accordance with, the laws of Bermuda.

                                 -----
of the Executive's obligations under Section 2(a)(ii) (other than as a result of
physical or mental incapacity) which constitutes a continued material
nonperformance by the Executive of her obligations and duties thereunder, as
reasonably determined by the Board, and which is not remedied within 30 days
after receipt of written notice from the Company specifying such breach, (ii)
commission by the Executive of an act of fraud upon, or willful misconduct
toward, the Company or any Affiliate (as defined below in this

                                       3
<PAGE>

deemed disinterested for this purpose) after a hearing by the Board following
ten days' notice to the Executive of such hearing, (iii) a material breach by
the Executive of Section 6 or Section 9, (iv) the conviction of the Executive of
any felony or crime of moral turpitude (or a plea of nolo contendere thereto) or

the power, whether by contract, equity ownership or otherwise, to direct the
policies or management of a Person; and "Person" means an individual,
                                         ------

organization, or a government or agency or political subdivision thereof.

         (c) Good Reason. The Executive's employment may be terminated during
             -----------
the Employment Period by the Executive for Good Reason or without Good Reason;
provided, however, that the Executive agrees not to terminate her employment for
- -----------------
Good Reason unless (i) the Executive has given the Company at least 30 days'
prior written notice of her intent to terminate her employment for Good Reason,
which notice shall specify the facts and circumstances constituting Good Reason
and (ii) the Company has not remedied such facts and circumstances constituting
Good Reason within such 30-day period. For purposes of this Agreement, "Good
                                                                        ----
Reason" shall mean:
- ------

           (i) the assignment to the Executive of any duties inconsistent in any

faith and which is remedied by the Company promptly after receipt of notice
thereof given by the Executive; provided, however, that Good Reason may not be
asserted by the Executive under this clause (i) of Section 3(c) after a Non-
Renewal Notice has been given by either the Company or the Executive;

           (ii) any termination or material reduction of the Executive's
compensation or benefits set forth in this Agreement;

           (iii) any failure by the Company to comply with any of the provisions
of Section 2(b), other than an isolated, insubstantial and inadvertent failure
not occurring in bad faith and which is remedied by the Company promptly after
receipt of notice thereof given by the Executive;

           (iv) any failure by the Company to comply with and satisfy
Section 8(c); or

                                       4

           (v) without limiting the generality of the foregoing, any material
breach by the Company or any of its subsidiaries or other Affiliates of this
Agreement.

         (d) Notice of Termination.  Any termination by the Company for Cause
             ---------------------
or without Cause, or by the Executive for Good Reason or without Good Reason,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 11(b).  For purposes of this Agreement, a "Notice of
                                                                      ---------

indicated and (iii) if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date (which date
shall not be more than 15 days after the giving of such notice).  The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

         (e) Date of Termination.  "Date of Termination" means (i) if the
             -------------------    -------------------
Executive's employment is terminated by the Company for Cause or without Cause,
or by the Executive for Good Reason or without Good Reason, the date of receipt
of the Notice of Termination or any later date specified therein pursuant to

terminated by reason of death or Disability, the date of death of the Executive
or the Disability Effective Date, as the case may be.

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

<PAGE>

               (2) 200% of the Executive's then current Annual Base Salary;
           provided, however, that in the case of termination of employment due
           to death or Disability, (A) the aforesaid 200% of the Executive's
           then current Annual Base Salary shall not be paid or owed and (B) the
           Company shall pay an amount equal to the portion of the Annual Base
           Salary that otherwise would have been paid had the Executive remained

           through the expiration of the Employment Period;

               (3) a pro rata portion of the Bonus that has been awarded
           (if any) to the Executive for the calendar year in which such
           termination occurs that would have been payable to the Executive
           pursuant to Section 2(b)(ii) hereof for such calendar year if such
           Executive had remained in the employ of the Company through the end
           of such calendar year, based upon the number of days during such
           calendar year prior to the Date of Termination (the "Accrued Bonus");
                                                                -------------
           and

               (4) any amount arising from Executive's participation in, or

which have already vested shall be as provided in the Option Agreement.

         (d) If pursuant to the terms and provisions of the Company's Welfare

in the Company's Welfare Plans because the Executive is no longer an employee of
the Company, then the Company may fulfill its obligations under Section 4(a)(ii)
or Section 4(b), as applicable, by either providing to the Executive (or her
legal representatives), or reimbursing the Executive (or her legal
representatives) for the costs of, benefits substantially similar to the

Executive be obligated to seek other employment or take any other action by way
of mitigation of the amounts payable to the Executive under any of the

         (b) The Executive agrees (i) to hold the Confidential Information in
confidence and (ii) not to release such information to any Person (other than

Information for the benefit of any Person other than the Company and its
Affiliates.

         (d) To the extent permitted by law, all rights worldwide with respect

and deliver to the Company, at the Company's request, such further documents as
the Company finds appropriate to evidence the Company's rights in such property.

         (e) The Executive agrees to sign the Company's standard form of

Information and other properties of the Company and its Affiliates which are in
the Executive's possession, custody or control.

     8.  Successors and Assigns.
         ----------------------

         (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

         (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns and the Company shall have the right
to assign this Agreement.

         (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement,

                                       8
<PAGE>

"Company" shall mean the Company as hereinbefore defined and any successor to
its business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law, or otherwise.

     9.  Non-Competition.
         ---------------

         (a) The Executive covenants and agrees with the Company that, while
she is an employee of the Company or any Affiliate thereof and for a period of
two years thereafter she will not, without the prior written consent of the
Company, either directly or indirectly:

           (i) solicit any contractors, customers or distributors of the Company
or any Affiliate thereof or endeavor to entice away from the Company or any
Affiliate thereof any such Person or otherwise interfere with the relationship
between such Person and the Company or any Affiliate thereof for the purposes of
competing with the Company or any Affiliate thereof;

           (ii) endeavor to entice away from the Company or any Affiliate
thereof any person who is employed by the Company or any Affiliate thereof,
either directly or indirectly, or interfere in any way with the
employer/employee relations between any such employee and the Company or any
Affiliate thereof; or

           (iii) offer employment to any person who was employed by the
Company or any Affiliate thereof at the date upon which the Executive ceases to
be an employee of the Company or any Affiliate thereof.

         (b) The Executive covenants and agrees with the Company and each
Affiliate thereof that (i) while she is an employee of the Company or any
Affiliate thereof she shall not directly or indirectly compete in any manner
against the Company or any of its Affiliates and (ii) and for a period of two
years following the date she ceases such employment for whatever reason, she
will not, directly or indirectly, in any manner whatsoever, including either
individually or in partnership or jointly or in conjunction with any other
Person, as principal, agent, shareholder, employee or in any other manner
whatsoever, carry on or be engaged in or concerned with or interested in or lend
money to, guarantee the debts or obligations of or permit her name to be used by
a Competitive Business (as defined below).

         (c) For the purposes of this Section 9, a "Competitive Business" shall
                                                    --------------------
mean any business relating to or involving (A) the ownership (as a principal
business, and/or the construction and/or operation of any submarine cable system
which is located or is to be located between (1) Bermuda and the United States
of America, (2) Bermuda and South America, (3) the United States of America and
South America or (4) any two or more countries or continents if the Company or
any Affiliate thereof is constructing, owning and/or operating or is to
construct, own and/or operate any submarine cable system between any such
countries or continents during the Executive's employment

                                       9
<PAGE>

hereunder or (B) telecommunication services (including electronic commerce) in
Bermuda.

         (d) The foregoing covenants are given by the Executive acknowledging
that she has specific knowledge of the affairs of the Company and its
Affiliates.

         (e) The Executive acknowledges and agrees that the nature of the
Confidential Information to which she will have access during her employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for her to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if she were to
perform in a similar capacity for a Competitive Business it would be inevitable
that she would disclose and/or use Confidential Information.

         (f) The Executive acknowledges that violations of the provisions of
Section 6 or 9 will cause immediate and irreparable harm to the Company,
entitling the Company to an injunction in or by a court of competent
jurisdiction or arbitration in addition to any other remedies the Company may
have at law or in equity, including recovery of reasonable attorneys' fees and
costs incurred by the Company in enforcing the provisions of Section 6 or 9.  In
the event that any covenant contained in Section 9 or portion of any such
covenant should be unenforceable or be declared invalid for any reason
whatsoever, such unenforceability or invalidity shall not affect the
enforceability or validity of the remaining portions of the covenants and such
unenforceable or invalid portions shall be severable from the remainder of this
Agreement.  The Executive hereby acknowledges and agrees that all restrictions
contained in this Section 9 are reasonable and valid and all defenses to the
strict enforcement thereof by the Company and are hereby waived by her.

         (g) Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in her personal capacity unless such
investments are of a type that may conflict with the efficient performance of
her duties or with any of her obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

         (h) The Executive acknowledges and agrees that she has received good
and valuable consideration in exchange for her covenants and obligations under
this Agreement.

     10. Effect of Agreement on Other Benefits.  The existence of
         -------------------------------------
this Agreement shall not prohibit or restrict the Executive's entitlement to
full participation in the executive compensation, employee benefit and other
plans or programs in which executives of the Company are eligible to
participate.

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

         (a) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF NEW YORK WITHOUT REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS.
The captions of this Agreement are not part of the provisions hereof and shall
have no force or effect.  Whenever the terms "hereof", "hereby", "herein", or
                                              ------    ------    ------
words of similar import are used in this Agreement they shall be construed as

                           -------      ---------
referring to the indicated section or paragraph of this Agreement unless the
context indicates to the contrary.  The use of the term "including" herein shall
                                                         ---------
be construed as meaning "including without limitation."  This Agreement may not
                         ----------------------------
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

         (b) All notices and other communications hereunder shall be in writing
and shall be given by hand delivery to the other party or by registered or

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

         (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a

                                       11
<PAGE>

provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         (d) The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

         (e) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

         (f) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

         (g) The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof, and this Agreement supersedes any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof,
including, but not limited to, that certain Executive Employment Agreement Term
Sheet between the Company and the Executive dated July 14, 1999.

         (h) This Agreement may be executed in two or more counterparts.

         (i)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(i).

              (ii) Any and all Disputes that are not resolved through
negotiation as set forth above shall be finally settled in a binding arbitration
administered by the American Arbitration Association (the "AAA") under its
                                                           ---
Commercial Arbitration Rules then in effect. The place of arbitration shall be
New York, New York. If the parties are unable to agree on the appointment of a
single arbitrator to conduct the
                                       12
<PAGE>

arbitration within 20 days after the claimant has filed its demand for
arbitration, then the arbitration shall be conducted by a panel of three
arbitrators, appointed as follows: The Company and the Executive each shall
appoint one arbitrator, and the two arbitrators so appointed shall appoint the
third arbitrator, who shall chair the panel. No arbitrator may be affiliated,
associated, or related to the Company, any Affiliate, employee or executive of
the Company, or the Executive in any manner whatsoever.

              (iii) The award of the arbitrators shall be final and binding, and
judgment upon any such award may be entered by any court of competent
jurisdiction.  The arbitrators shall have no authority to award damages in
excess of compensatory damages, and each party hereby irrevocably waives any
right to recover such non-compensatory damages (including exemplary damages,
treble damages, and any other penalty or type of punitive damages) with respect
to any Dispute arising hereunder.  Each party shall bear such party's own
expenses related to any arbitration, but the parties shall share equally the
expenses of the arbitration tribunal and the AAA.

         (j) This Section 11(j) and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

         (k) The Executive represents and warrants to the Company that, to the
best of her personal knowledge and belief, neither the execution and  delivery
of this Agreement, her commencement of employment hereunder nor the performance
of her duties hereunder conflicts with any contractual commitment on her part
owed to any third party or violates or interferes with any rights of any third
party.

         (l) The Company or any of its Affiliates shall have the right to
secure, in its own name or otherwise, and at its own expense, life, disability,
accident or other insurance covering the Executive and the Executive shall have
no right, title or interest in or to such insurance. The Executive shall assist
the Company in procuring such insurance by submitting to reasonable examinations
and signing such applications and other instruments as may be required by the
insurance carriers to which applications is made for any such insurance.

         (m) At the request of the Company, the Executive shall (unless the
Executive has already done so) execute the necessary documents to become a party
to (i) the Amended and Restated Securityholders' Agreement dated July 14, 1999,
by and among GlobeNet and various other parties including various shareholders
of GlobeNet and (ii) the Registration Rights Agreement referred to therein.

          IN WITNESS WHEREOF, the Executive has hereunto set the Executive's

this Agreement to be executed in its name on its behalf, all as of the day and
year first above written.

nonperformance by the Executive of his obligations and duties thereunder, as
reasonably determined by the Board, and which is not remedied within 30 days
after receipt of written notice from the Company specifying such breach, (ii)
commission by the Executive of an act of fraud upon, or willful misconduct

deemed disinterested for this purpose) after a hearing by the Board following
ten days' notice to the Executive of such hearing, (iii) a material breach by
the Executive of Section 6 or Section 9, (iv) the conviction of the Executive of
any felony or crime of moral turpitude (or a plea of nolo contendere thereto) or

(v) the failure of the Executive to carry out, or comply with, in any material
respect any lawful directive of the Chief Executive Officer or President of the
Company or the Board consistent with the terms of this Agreement, which is not
remedied within 30 days after receipt of written notice from the Company

partnership, corporation, limited liability company, trust or unincorporated
organization, or a government or agency or political subdivision thereof.

     (c) Good Reason.  The Executive's employment may be terminated during the
         -----------
Employment Period by the Executive for Good Reason or without Good Reason;
provided, however, that the Executive agrees not to terminate his employment for
- --------  -------
Good Reason unless (i) the Executive has given the Company at least 30 days'
prior written notice of his intent to terminate his employment for Good Reason,
which notice shall specify the facts and circumstances constituting Good Reason
and (ii) the Company has not remedied such facts and circumstances constituting
Good Reason within such 30-day period.  For purposes of this Agreement, "Good
                                                                         ----
Reason" shall mean:
- ------

          (i) the assignment to the Executive of any duties inconsistent in any

faith and which is remedied by the Company promptly after receipt of notice
thereof given by the Executive; provided, however, that Good Reason may not be
asserted by the Executive under this clause (i) of Section 3(c) after a Non-

compensation or benefits set forth in this Agreement;

          (iv) any failure by the Company to comply with and satisfy Section
8(c); or

                                       4

          (v) without limiting the generality of the foregoing, any material
breach by the Company or any of its subsidiaries or other Affiliates of this
Agreement.

          (d) Notice of Termination.  Any termination by the Company for Cause
              ---------------------
or without Cause, or by the Executive for Good Reason or without Good Reason,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 11(b).  For purposes of this Agreement, a "Notice of
                                                                      ---------

indicated and (iii) if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date (which date
shall not be more than 15 days after the giving of such notice).  The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

          (e) Date of Termination.  "Date of Termination" means (i) if the
              -------------------    -------------------
Executive's employment is terminated by the Company for Cause or without Cause,
or by the Executive for Good Reason or without Good Reason, the date of receipt
of the Notice of Termination or any later date specified therein pursuant to

          (d) If pursuant to the terms and provisions of the Company's Welfare

legal representatives), or reimbursing the Executive (or his legal
representatives) for the costs of, benefits substantially similar to the
benefits provided by the Company to its management under its Welfare Plans as
such may from time to time exist after the Date of Termination.

obtains other employment. Neither the Executive nor the Company shall be liable
to the other party for any damages or other amounts in addition to the amounts
payable under Section 4 arising out of the termination or non-renewal of the

indirect, by purchase, merger, consolidation or otherwise) to all or

hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

     9.   Non-Competition.
          ---------------

          (a) The Executive covenants and agrees with the Company that, while he
is an employee of the Company or any Affiliate thereof and for a period of two
years thereafter he will not, without the prior written consent of the Company,
either directly or indirectly:

          (i) solicit any contractors, customers or distributors of the Company
or any Affiliate thereof or endeavor to entice away from the Company or any
Affiliate thereof any such Person or otherwise interfere with the relationship
between such Person and the Company or any Affiliate thereof for the purposes of
competing with the Company or any Affiliate thereof;

          (ii) endeavor to entice away from the Company or any Affiliate thereof
any person who is employed by the Company or any Affiliate thereof, either
directly or indirectly, or interfere in any way with the employer/employee
relations between any such employee and the Company or any Affiliate thereof; or

          (iii) offer employment to any person who was employed by the Company
or any Affiliate thereof at the date upon which the Executive ceases to be an
employee of the Company or any Affiliate thereof.

          (b) The Executive covenants and agrees with the Company and each
Affiliate thereof that (i) while he is an employee of the Company or any
Affiliate thereof he shall not directly or indirectly compete in any manner
against the Company or any of its Affiliates and (ii) and for a period of two
years following the date he ceases such employment for whatever reason, he will
not, directly or indirectly, in any manner whatsoever, including either
individually or in partnership or jointly or in conjunction with any other
Person, as principal, agent, shareholder, employee or in any other manner
whatsoever, carry on or be engaged in or concerned with or interested in or lend
money to, guarantee the debts or obligations of or permit his name to be used by
a Competitive Business (as defined below).

          (c) For the purposes of this Section 9, a "Competitive Business" shall
                                                     --------------------
mean any business relating to or involving (A) the ownership (as a principal
business) and/or the construction and/or operation of any submarine cable system
which is located or is to be located between (1) Bermuda and the United States
of America, (2) Bermuda

                                       9
<PAGE>

electronic commerce) in Bermuda.

          (d) The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

          (e) The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if he were to
perform in a similar capacity for a Competitive Business it would be inevitable
that he would disclose and/or use Confidential Information.

          (f) The Executive acknowledges that violations of the provisions of
Section 6 or 9 will cause immediate and irreparable harm to the Company,
entitling the Company to an injunction in or by a court of competent
jurisdiction or arbitration in addition to any other remedies the Company may
have at law or in equity, including recovery of reasonable attorneys' fees and
costs incurred by the Company in enforcing the provisions of Section 6 or 9.  In
the event that any covenant contained in Section 9 or portion of any such
covenant should be unenforceable or be declared invalid for any reason
whatsoever, such unenforceability or invalidity shall not affect the
enforceability or validity of the remaining portions of the covenants and such
unenforceable or invalid portions shall be severable from the remainder of this
Agreement.  The Executive hereby acknowledges and agrees that all restrictions
contained in this Section 9 are reasonable and valid and all defenses to the
strict enforcement thereof by the Company and are hereby waived by him.

          (g) Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

          (h) The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
this Agreement.

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

          (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a

                                       11
<PAGE>

provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

          (d) The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

          (e) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

          (f) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

          (g) The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof and this Agreement supersedes any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof,
including, but not limited to, that certain Executive Employment Agreement Term
Sheet between the Company and the Executive dated July 14, 1999.

          (h) This Agreement may be executed in two or more counterparts.

          (i)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(i).

               (ii) Any and all Disputes that are not resolved through
negotiation as set forth above shall be finally settled in a binding arbitration
administered by the American Arbitration Association (the "AAA") under its
                                                           ---
Commercial Arbitration Rules then in effect. The place of arbitration shall be
New York, New York. If the parties are unable to agree on the appointment of a
single arbitrator to conduct the

                                       12
<PAGE>

arbitration within 20 days after the claimant has filed its demand for
arbitration, then the arbitration shall be conducted by a panel of three
arbitrators, appointed as follows: The Company and the Executive each shall
appoint one arbitrator, and the two arbitrators so appointed shall appoint the
third arbitrator, who shall chair the panel. No arbitrator may be affiliated,
associated, or related to the Company, any Affiliate, employee or executive of
the Company, or the Executive in any manner whatsoever.

               (iii) The award of the arbitrators shall be final and binding,
and judgment upon any such award may be entered by any court of competent
jurisdiction. The arbitrators shall have no authority to award damages in excess
of compensatory damages, and each party hereby irrevocably waives any right to
recover such non-compensatory damages (including exemplary damages, treble
damages, and any other penalty or type of punitive damages) with respect to any
Dispute arising hereunder. Each party shall bear such party's own expenses
related to any arbitration, but the parties shall share equally the expenses of
the arbitration tribunal and the AAA.

          (j) This Section 11(j) and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

          (k) The Executive represents and warrants to the Company that, to the
best of his personal knowledge and belief, neither the execution and delivery of
this Agreement, his commencement of employment hereunder nor the performance of
his duties hereunder conflicts with any contractual commitment on his part owed
to any third party or violates or interferes with any rights of any third party.

          (l) The Company or any of its Affiliates shall have the right to
secure, in its own name or otherwise, and at its own expense, life, disability,
accident or other insurance covering the Executive and the Executive shall have
no right, title or interest in or to such insurance. The Executive shall assist
the Company in procuring such insurance by submitting to reasonable examinations
and signing such applications and other instruments as may be required by the
insurance carriers to which applications is made for any such insurance.

          (m) At the request of the Company, the Executive shall (unless the
Executive has already done so) execute the necessary documents to become a party
to (i) the Amended and Restated Securityholders' Agreement dated July 14, 1999,
by and among GlobeNet and various other parties including various shareholders
of GlobeNet and (ii) the Registration Rights Agreement referred to therein.

     IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand
and, pursuant to the authorization from the Board, the Company has caused this
Agreement to be executed in its name on its behalf, all as of the day and year
first above written.

                             -----
the Executive's obligations under Section 2(a)(ii) (other than as a result of
physical or mental incapacity) which constitutes a continued material
nonperformance by the Executive of his obligations and duties thereunder, as
reasonably determined by the Board, and which is not remedied within 30 days
after receipt of written notice from the Company specifying such breach,
(ii) commission by the Executive of an act of fraud upon, or willful misconduct
toward, the Company or any Affiliate (as defined below in this

                                       3
<PAGE>

Section 3(b)), as reasonably determined by a majority of the disinterested
members of the Board (neither the Executive nor members of his family being
deemed disinterested for this purpose) after a hearing by the Board following
ten days' notice to the Executive of such hearing, (iii) a material breach by
the Executive of Section 6 or Section 9, (iv) the conviction of the Executive of
any felony or crime of moral turpitude (or a plea of nolo contendere thereto) or

(v) the failure of the Executive to carry out, or comply with, in any material
respect any lawful directive of the Chief Executive Officer or President of the
Company or the Board consistent with the terms of this Agreement, which is not
remedied within 30 days after receipt of written notice from the Company
specifying such failure. As used in this Agreement, "Affiliate" means, with
                                                     ---------
respect to a Person, any other Person controlling, controlled by or under common
control with the first Person; the term "control," and correlative terms, means
                                         -------
the power, whether by contract, equity ownership or otherwise, to direct the
policies or management of a Person; and "Person" means an individual,
                                         ------
partnership, corporation, limited liability company, trust or unincorporated
organization, or a government or agency or political subdivision thereof.

     (c) Good Reason.  The Executive's employment may be terminated during the
         -----------
Employment Period by the Executive for Good Reason or without Good Reason;

provided, however, that the Executive agrees not to terminate his employment for
- --------  -------
Good Reason unless (i) the Executive has given the Company at least 30 days'
prior written notice of his intent to terminate his employment for Good Reason,
which notice shall specify the facts and circumstances constituting Good Reason
and (ii) the Company has not remedied such facts and circumstances constituting
Good Reason within such 30-day period.  For purposes of this Agreement, "Good
                                                                         ----
Reason" shall mean:
- ------

     (i) the assignment to the Executive of any duties inconsistent in any
respect with the Executive's position (including status, offices, titles and
reporting requirements), authority, duties or responsibilities, excluding for
this purpose an isolated, insubstantial and inadvertent action not taken in bad
faith and which is remedied by the Company promptly after receipt of notice
thereof given by the Executive; provided, however, that Good Reason may not be
asserted by the Executive under this clause (i) of Section 3(c) after a Non-
Renewal Notice has been given by either the Company or the Executive;

     (ii) any termination or material reduction of the Executive's compensation
or benefits set forth in this Agreement;

     (iii)  any failure by the Company to comply with any of the provisions of
Section 2(b), other than an isolated, insubstantial and inadvertent failure not
occurring in bad faith and which is remedied by the Company promptly after
receipt of notice thereof given by the Executive;

     (iv) any failure by the Company to comply with and satisfy Section 8(c); or

                                       4
<PAGE>

     (v) without limiting the generality of the foregoing, any material
breach by the Company or any of its subsidiaries or other Affiliates of this
Agreement.

     (d) Notice of Termination.  Any termination by the Company for Cause
         ---------------------
or without Cause, or by the Executive for Good Reason or without Good Reason,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 11(b).  For purposes of this Agreement, a "Notice of
                                                                      ---------
Termination" means a written notice which (i) indicates the specific termination
- -----------
provision in this Agreement relied upon, (ii) to the extent applicable, sets

indicated and (iii) if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date (which date
shall not be more than 15 days after the giving of such notice).  The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

     (e) Date of Termination.  "Date of Termination" means (i) if the
         -------------------    -------------------
Executive's employment is terminated by the Company for Cause or without Cause,
or by the Executive for Good Reason or without Good Reason, the date of receipt
of the Notice of Termination or any later date specified therein pursuant to
Section 3(d), as the case may be and (ii) if the Executive's employment is
terminated by reason of death or Disability, the date of death of the Executive
or the Disability Effective Date, as the case may be.

     4. Obligations of the Company upon Termination.
        -------------------------------------------

     (a) Good Reason; Death or Disability.  If, during the Employment
         --------------------------------
Period, the Company shall terminate the Executive's employment without Cause or
due to the Executive's Disability or the Executive shall terminate his
employment for Good Reason, or the Executive's employment is terminated due to
the Executive's death:

     (i) The Company shall (except as otherwise hereinafter provided) pay
to the Executive (or the Executive's legal representatives in the case of death
or Disability of the Executive) in a lump sum in cash within ten days after the
Date of Termination the aggregate of the following amounts:

     (1) the portion of the Annual Base Salary through the Date of Termination
to the extent not theretofore paid and any compensation previously deferred by
the Executive and any accrued vacation pay ("Accrued Obligations");
                                             ------- -----------

Confidential Information shall not include (i) information that is generally
known to other Persons who can obtain economic value from its disclosure or use
and (ii) information required to be disclosed by the Executive pursuant to a
subpoena or court order, or pursuant to a requirement of a governmental agency

     (b) The Executive agrees (i) to hold the Confidential Information in
confidence and (ii) not to release such information to any Person (other than

such knowledge) or as required pursuant to Section 6(a)(ii) above.

     (c) The Executive further agrees not to use any Confidential Information
for the benefit of any Person other than the Company and its Affiliates.

     (d) To the extent permitted by law, all rights worldwide with respect
to any and all intellectual or other property of any nature produced, created or
suggested by the Executive during the Employment Period or resulting from his

exclusive property of the Company. The Executive agrees to execute, acknowledge
and deliver to the Company, at the Company's request, such further documents as
the Company finds appropriate to evidence the Company's rights in such property.

     (e) The Executive agrees to sign the Company's standard form of
confidentiality agreement at the request of the Company.

     7. Surrender of Materials Upon Termination.  Upon any termination of the
        ---------------------------------------

all copies, in whatever form, of any and all Confidential Information and other
properties of the Company and its Affiliates which are in the Executive's
possession, custody or control.

     8. Successors and Assigns.
        ----------------------

     (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.  This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

     (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns and the Company shall have the right
to assign this Agreement.

                                       8
<PAGE>

     (c) The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

     9. Non-Competition.
        ---------------

     (a) The Executive covenants and agrees with the Company that, while he
is an employee of the Company or any Affiliate thereof and for a period of two
years thereafter he will not, without the prior written consent of the Company,
either directly or indirectly:

     (i) solicit any contractors, customers or distributors of the Company
or any Affiliate thereof or endeavor to entice away from the Company or any
Affiliate thereof any such Person or otherwise interfere with the relationship
between such Person and the Company or any Affiliate thereof for the purposes of
competing with the Company or any Affiliate thereof;

     (ii) endeavor to entice away from the Company or any Affiliate thereof
any person who is employed by the Company or any Affiliate thereof, either
directly or indirectly, or interfere in any way with the employer/employee
relations between any such employee and the Company or any Affiliate thereof; or

     (iii) offer employment to any person who was employed by the Company or
any Affiliate thereof at the date upon which the Executive ceases to be an
employee of the Company or any Affiliate thereof.

     (b) The Executive covenants and agrees with the Company and each
Affiliate thereof that (i) while he is an employee of the Company or any
Affiliate thereof he shall not directly or indirectly compete in any manner
against the Company or any of its Affiliates and (ii) and for a period of two
years following the date he ceases such employment for whatever reason, he will
not, directly or indirectly, in any manner whatsoever, including either
individually or in partnership or jointly or in conjunction with any other
Person, as principal, agent, shareholder, employee or in any other manner
whatsoever, carry on or be engaged in or concerned with or interested in or lend
money to, guarantee the debts or obligations of or permit his name to be used by
a Competitive Business (as defined below).

     (c) For the purposes of this Section 9, a "Competitive Business" shall
                                                     --------------------
mean any business relating to or involving (A) the ownership (as a principal
business) and/or the construction and/or operation of any submarine cable system
which is located or is to be located between (1) Bermuda and the United States
of America, (2) Bermuda

                                       9
<PAGE>

and South America, (3) the United States of America and South America or (4) any
two or more countries or continents if the Company or any Affiliate thereof is
constructing, owning and/or operating or is to construct, own and/or operate any
submarine cable system between any such countries or continents during the
Executive's employment hereunder or (B) telecommunication services (including
electronic commerce) in Bermuda.

     (d) The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

     (e) The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if he were to
perform in a similar capacity for a Competitive Business it would be inevitable
that he would disclose and/or use Confidential Information.

     (f) The Executive acknowledges that violations of the provisions of
Section 6 or 9 will cause immediate and irreparable harm to the Company,
entitling the Company to an injunction in or by a court of competent
jurisdiction or arbitration in addition to any other remedies the Company may
have at law or in equity, including recovery of reasonable attorneys' fees and
costs incurred by the Company in enforcing the provisions of Section 6 or 9.  In
the event that any covenant contained in Section 9 or portion of any such
covenant should be unenforceable or be declared invalid for any reason
whatsoever, such unenforceability or invalidity shall not affect the
enforceability or validity of the remaining portions of the covenants and such
unenforceable or invalid portions shall be severable from the remainder of this
Agreement.  The Executive hereby acknowledges and agrees that all restrictions
contained in this Section 9 are reasonable and valid and all defenses to the
strict enforcement thereof by the Company and are hereby waived by him.

     (g) Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

     (h) The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
this Agreement.

     10. Effect of Agreement on Other Benefits.  The existence of this Agreement
         -------------------------------------
shall not prohibit or restrict the Executive's entitlement to full participation
in the executive compensation, employee benefit and other plans or programs in
which executives of the Company are eligible to participate.

     11. Miscellaneous.
         -------------

     (a) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE PROVINCE OF ONTARIO WITHOUT REFERENCE TO PRINCIPLES OF
CONFLICT OF LAWS.  The captions of this Agreement are not part of the provisions
hereof and shall have no force or effect.  Whenever the terms "hereof",

"hereby", "herein", or words of similar import are used in this Agreement they
 ------    ------
shall be construed as referring to this Agreement in its entirety rather than to
a particular section or provision, unless the context specifically indicates to
the contrary.  Any reference to a particular "Section" or "paragraph" shall be
                                              -------      ---------
construed as referring to the indicated section or paragraph of this Agreement
unless the context indicates to the contrary.  The use of the term "including"
                                                                    ---------
herein shall be construed as meaning "including without limitation."  This
                                      ----------------------------
Agreement may not be amended or modified otherwise than by a written agreement
executed by the parties hereto or their respective successors and legal
representatives.

     (b) All notices and other communications hereunder shall be in writing
and shall be given by hand delivery to the other party or by registered or
certified mail, return receipt requested, postage prepaid, addressed as follows:

     If to the Company:      TeleBermuda International (Canada) Limited
     -----------------
                             3100 Steeles Avenue East, Suite 805
                             Markham, Ontario L3R 8T3

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

     (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or

                                       11
<PAGE>

unenforceable provision there shall be added automatically as part of this
Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

     (d) The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

     (e) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

     (f) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

     (g) The provisions of this Agreement constitute the complete understanding
and agreement between the parties with respect to the subject matter hereof, and
this Agreement supersedes any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof, including, but not
limited to, that certain Executive Employment Agreement Term Sheet between the
Company and the Executive dated July 14, 1999 and that certain Employment
Contract between the Company and the Executive dated October 7, 1996.

     (h) This Agreement may be executed in two or more counterparts.

     (i)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(i).

          (ii) Any and all Disputes that are not resolved through negotiation as
set forth above shall be finally settled in a binding arbitration administered
by the American Arbitration Association (the "AAA") under its Commercial
                                              ---
Arbitration

                                       12
<PAGE>

Rules then in effect. The place of arbitration shall be New York, New York. If
the parties are unable to agree on the appointment of a single arbitrator to
conduct the arbitration within 20 days after the claimant has filed its demand
for arbitration, then the arbitration shall be conducted by a panel of three
arbitrators, appointed as follows: The Company and the Executive each shall
appoint one arbitrator, and the two arbitrators so appointed shall appoint the
third arbitrator, who shall chair the panel. No arbitrator may be affiliated,
associated, or related to the Company, any Affiliate, employee or executive of
the Company, or the Executive in any manner whatsoever.

          (iii)  The award of the arbitrators shall be final and binding, and
judgment upon any such award may be entered by any court of competent
jurisdiction.  The arbitrators shall have no authority to award damages in
excess of compensatory damages, and each party hereby irrevocably waives any
right to recover such non-compensatory damages (including exemplary damages,
treble damages, and any other penalty or type of punitive damages) with respect
to any Dispute arising hereunder.  Each party shall bear such party's own
expenses related to any arbitration, but the parties shall share equally the
expenses of the arbitration tribunal and the AAA.

     (j) This Section 11(j) and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

     (k) The Executive represents and warrants to the Company that, to the
best of his personal knowledge and belief, neither the execution and  delivery
of this Agreement, his commencement of employment hereunder nor the performance
of his duties hereunder conflicts with any contractual commitment on his part
owed to any third party or violates or interferes with any rights of any third
party.

     (l) The Company or any of its Affiliates shall have the right to
secure, in its own name or otherwise, and at its own expense, life, disability,
accident or other insurance covering the Executive and the Executive shall have
no right, title or interest in or to such insurance. The Executive shall assist
the Company in procuring such insurance by submitting to reasonable examinations
and signing such applications and other instruments as may be required by the
insurance carriers to which applications is made for any such insurance.

     (m) At the request of the Company, the Executive shall (unless the
Executive has already done so) execute the necessary documents to become a party
to (i) the Amended and Restated Securityholders' Agreement dated July 14, 1999,
by and among GlobeNet and various other parties including various shareholders
of GlobeNet and (ii) the Registration Rights Agreement referred to therein.

          IN WITNESS WHEREOF, the Executive has hereunto set the Executive's
hand and, pursuant to the authorization from the Board, the Company has caused
this Agreement to be executed in its name on its behalf, all as of the day and
year first above written.

prior written notice of his intent to terminate his employment for Good Reason,
which notice shall specify the facts and circumstances constituting Good Reason
and (ii) the Company has not remedied such facts and circumstances constituting

accordance with Section 11(b). For purposes of this Agreement, a "Notice of
                                                                  ---------

shall not be more than 15 days after the giving of such notice). The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company hereunder or preclude the
Executive or the Company from asserting such fact or circumstance in enforcing
the Executive's or the Company's rights hereunder.

     (e) Date of Termination. "Date of Termination" means (i) if the

vested shall be as provided in the Option Agreement.

     (d) If pursuant to the terms and provisions of the Company's Welfare

legal representatives), or reimbursing the Executive (or his legal
representatives) for the costs of, benefits substantially similar to the
benefits provided by the Company to its management under its Welfare Plans as
such may from time to time exist after the Date of Termination.

obligated to seek other employment or take any other action by way of mitigation

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

     (a)  The Executive covenants and agrees with the Company that, while he

years thereafter he will not, without the prior written consent of the Company,
either directly or indirectly:

any Affiliate thereof or endeavor to entice away from the Company or any
Affiliate thereof any such Person or otherwise interfere with the relationship
between such Person and the Company or any Affiliate thereof for the purposes of
competing with the Company or any Affiliate thereof;

     (ii) endeavor to entice away from the Company or any Affiliate thereof any
person who is employed by the Company or any Affiliate thereof, either directly
or indirectly, or interfere in any way with the employer/employee relations
between any such employee and the Company or any Affiliate thereof; or

     (iii) offer employment to any person who was employed by the Company or any
Affiliate thereof at the date upon which the Executive ceases to be an employee
of the Company or any Affiliate thereof.

     (b)  The Executive covenants and agrees with the Company and each
Affiliate thereof that (i) while he is an employee of the Company or any
Affiliate thereof he shall not directly or indirectly compete in any manner
against the Company or any of its Affiliates and (ii) and for a period of two
years following the date he ceases such employment for whatever reason, he will
not, directly or indirectly, in any manner whatsoever, including either
individually or in partnership or jointly or in conjunction with any other
Person, as principal, agent, shareholder, employee or in any other manner
whatsoever, carry on or be engaged in or concerned with or interested in or lend
money to, guarantee the debts or obligations of or permit his name to be used by
a Competitive Business (as defined below).

     (c)  For the purposes of this Section 9, a "Competitive Business" shall

business) and/or the construction and/or operation of any submarine cable system
which is located or is to be located between (1) Bermuda and the United States
of America, (2) Bermuda

                                       9

electronic commerce) in Bermuda.

     (d)  The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

     (e)  The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business without
disclosing or utilizing the Confidential Information and that if he were to
perform in a similar capacity for a Competitive Business it would be inevitable
that he would disclose and/or use Confidential Information.

     (f)  The Executive acknowledges that violations of the provisions of
Section 6 or 9 will cause immediate and irreparable harm to the Company,
entitling the Company to an injunction in or by a court of competent
jurisdiction or arbitration in addition to any other remedies the Company may
have at law or in equity, including recovery of reasonable attorneys' fees and
costs incurred by the Company in enforcing the provisions of Section 6 or 9. In
the event that any covenant contained in Section 9 or portion of any such
covenant should be unenforceable or be declared invalid for any reason
whatsoever, such unenforceability or invalidity shall not affect the
enforceability or validity of the remaining portions of the covenants and such
unenforceable or invalid portions shall be severable from the remainder of this
Agreement. The Executive hereby acknowledges and agrees that all restrictions
contained in this Section 9 are reasonable and valid and all defenses to the
strict enforcement thereof by the Company and are hereby waived by him.

     (g)  Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

     (h)  The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
this Agreement.

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

     (c) If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or

                                       11
<PAGE>

unenforceable provision there shall be added automatically as part of this
Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

     (d) The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

     (e) The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

     (f) The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of a
Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

     (g) The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof, and this Agreement supersedes any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof,
including, but not limited to, that certain Executive Employment Agreement Term
Sheet between the Company and the Executive dated July 14, 1999.

     (h) This Agreement may be executed in two or more counterparts.

     (i)  (i)  The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(i).

          (ii) Any and all Disputes that are not resolved through negotiation as
set forth above shall be finally settled in a binding arbitration administered
by the American Arbitration Association (the "AAA") under its Commercial
                                              ---
Arbitration Rules then in effect. The place of arbitration shall be New York,
New York. If the

                                       12
<PAGE>

parties are unable to agree on the appointment of a single arbitrator to conduct
the arbitration within 20 days after the claimant has filed its demand for
arbitration, then the arbitration shall be conducted by a panel of three
arbitrators, appointed as follows: The Company and the Executive each shall
appoint one arbitrator, and the two arbitrators so appointed shall appoint the
third arbitrator, who shall chair the panel. No arbitrator may be affiliated,
associated, or related to the Company, any Affiliate, employee or executive of
the Company, or the Executive in any manner whatsoever.

          (iii)  The award of the arbitrators shall be final and binding, and
judgment upon any such award may be entered by any court of competent
jurisdiction. The arbitrators shall have no authority to award damages in excess
of compensatory damages, and each party hereby irrevocably waives any right to
recover such non-compensatory damages (including exemplary damages, treble
damages, and any other penalty or type of punitive damages) with respect to any
Dispute arising hereunder. Each party shall bear such party's own expenses
related to any arbitration, but the parties shall share equally the expenses of
the arbitration tribunal and the AAA.

     (j) This Section 11(j) and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

     (k) The Executive represents and warrants to the Company that, to the best
of his personal knowledge and belief, neither the execution and delivery of this
Agreement, his commencement of employment hereunder nor the performance of his
duties hereunder conflicts with any contractual commitment on his part owed to
any third party or violates or interferes with any rights of any third party.

     (l) The Company or any of its Affiliates shall have the right to secure, in
its own name or otherwise, and at its own expense, life, disability, accident or
other insurance covering the Executive and the Executive shall have no right,
title or interest in or to such insurance. The Executive shall assist the
Company in procuring such insurance by submitting to reasonable examinations and
signing such applications and other instruments as may be required by the
insurance carriers to which applications is made for any such insurance.

     (m) At the request of the Company, the Executive shall (unless the
Executive has already done so) execute the necessary documents to become a party
to (i) the Amended and Restated Securityholders' Agreement dated July 14, 1999,
by and among GlobeNet and various other parties including various shareholders
of GlobeNet and (ii) the Registration Rights Agreement referred to therein.

     IN WITNESS WHEREOF, the Executive has hereunto set the Executive's

year first above written.
