               SERVICE OF PROCESS AND ENFORCEMENT OF LIABILITIES
 
  We are organized under the laws of Bermuda. In addition, certain of our
directors and officers live outside of the United States and a large amount of
our assets are located outside of the United States. As a result, it may be
difficult for you to effect service of process upon those directors and
officers who live outside the United States. Also, it may be difficult for you
to enforce judgments of the courts of the United States under the U.S. federal
securities laws against our assets that are located outside the United States.
Furthermore, our Bermuda counsel, Appleby Spurling & Kempe, has advised us that
it may be hard for you to bring a case in Bermuda based on U.S. federal
securities laws. They have also advised us that it may be difficult for you to
enforce a judgment of a U.S. court based upon U.S. federal securities laws.
 
  Since we are organized in a jurisdiction other than the United States, we
have expressly submitted to the jurisdiction of the U.S. federal and New York
state courts sitting the Borough of Manhattan, The City of New York for the
purposes of any suit action or proceeding arising out of this offering. We have
appointed CT Corporation to accept service of process in any such action.
 
                               ----------------
 
  In this prospectus, references to "dollars" and "$" are to United States
dollars, the terms "United States" and "U.S." mean the United States of
America, its states, its territories, its possessions and all areas subject to
its jurisdiction and the term "Exchange Offer" means the offer by Global
Crossing to exchange restricted preferred stock for unrestricted preferred
stock. See "Summary--Summary of Terms of the Exchange Offer."
 
                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS
 
  We have included "forward-looking statements" throughout this prospectus.
These statements describe our attempt to predict future occurrences. We use the
words "believes," "anticipates," "expects," and similar expressions to identify
forward-looking statements. Forward-looking statements are subject to a number
of risks, assumptions and uncertainties, such as:
 
  .  risks associated with our ability to complete our systems within
     currently estimated time frames and budgets,
 
  .  risks associated with our ability to sell capacity on our systems,
 
  .  risks associated with our successful transition from a system
     development company to an operating company, and
 
  .  risks associated with our ability to effectively compete in a rapidly
     evolving and price competitive marketplace.
 
  This list is only an example of some of the risks, uncertainties and
assumptions that may affect our forward-looking statements. If any of these
risks or uncertainties materialize (or fail to materialize), or if the
underlying assumptions prove incorrect, actual results may differ materially
from those projected in the forward-looking statements. We do not intend to
update or revise any forward-looking statements included in this prospectus to
reflect future events. You should consider the information provided in the
section "Risk Factors" and other information in this prospectus before
investing in these securities.

  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 this Exchange Offer you should read the entire
prospectus, especially "Risk Factors" and the Consolidated Financial Statements
and notes.
 
                                GLOBAL CROSSING
 
  We are developing the world's first independent global fiber optic network,
consisting of both undersea and terrestrial digital fiber optic cable systems.
We operate as a "carriers' carrier", providing tiered pricing and segmented
products to licensed providers of international Internet and telecommunications
services. Our cable systems under development will form a state-of-the-art
interconnected worldwide high capacity fiber optic network (the "Global
Crossing Network"). The undersea component of the Global Crossing Network will
initially total 51,300 km and the terrestrial component will add 8,400 km for a
combined total of 59,700 km. We are also planning several new cable systems and
evaluating other business development opportunities which, if implemented, will
complement the Global Crossing Network.
 
  Our business is designed to meet the varying needs of the global carrier
market. We offer customers the ability to purchase capacity which is available
on demand, thereby:
 
  .  eliminating their need to commit in advance the substantial capital
     which would otherwise be required to build cable capacity, and
 
  .  decreasing the risks associated with forecasting their future capacity
     requirements.
 
Compared with traditional cable systems, we offer more comprehensive, flexible
and low-cost purchasing alternatives.
 
  We meet current market requirements of international carriers and Internet
service providers and provide them with:
 
  .  direct international city-to-city connectivity,
 
  .  the ability to purchase capacity periodically,
 
  .  discounts based upon aggregate volume purchased on the Global Crossing
     Network, and
 
  .  one-stop shopping and customer service.
 
  We are engineering and constructing the Global Crossing Network to allow for
multiple upgrades to its initial circuit capacity at a fraction of the original
network cost. We are focusing on expanding the products and services we offer
to our customers in order to increase revenues and profits. We anticipate that
our future revenues, beyond the sale of capacity on the initial components of
the Global Crossing Network, will derive from several sources, including:
 
  .  the sale of additional capacity resulting from system upgrades,
 
  .  the development of additional undersea cable projects,
 
  .  the development or purchase of additional terrestrial fiber capacity,
     and
 
  .  the introduction of new services.

                               BUSINESS STRATEGY
 
  Global Crossing's mission is to create the world's first independent global
fiber optic network designed to offer the highest quality city-to-city
communications connectivity among approximately 100 of the largest metropolitan
communications markets worldwide. The principal elements of our business
strategy are to:
 
  Create a Worldwide Network. Upon completion, the currently announced segments
of the Global Crossing Network will directly connect Asia, North America,
Europe, Central America and the Caribbean utilizing state-of-the-art fiber
optic technology. By developing or acquiring terrestrial capacity, we offer
customers low cost global city-to-city connectivity. We also intend to actively
pursue additional opportunities for the expansion and utilization of the Global
Crossing Network, including complementary businesses and facilities.
 
  Maintain Position as a Leading Wholesale Service Provider. We are the world's
first independent provider of global Internet and long distance
telecommunications facilities and services utilizing a network of digital fiber
optic cable systems. Our products are segmented to meet the varying needs of
the global carrier market, with shore-to-shore capacity, city-to-city capacity
and network purchasing options. We also offer volume-based purchasing
flexibility.
 
  Utilize State-of-the-Art Technology. The Global Crossing Network is being
engineered and constructed using the latest cable technology which we believe
will:
 
  .  provide a cost advantage over existing alternatives,
 
  .  make it more reliable than competing systems,
 
  .  allow us to offer substantially more capacity than existing cable
     systems, and
 
  .  enable system capacity to be upgraded rapidly at a fraction of the
     initial cost.
 
  Maintain Position as Low-Cost Provider. Global Crossing believes that its
low-cost position results from:
 
  .  ownership of state-of-the-art facilities, resulting in low unit costs
     and low operating and maintenance costs,
 
  .  low sales, marketing and general and administrative costs, and
 
  .  purchasing efficiencies.
 
  Provide "One-Stop" Sales and Service. We offer one-stop sales and service to
carrier customers worldwide. Our marketing professionals located in our Bermuda
headquarters and in major cities throughout the world facilitate the sale of
our telecommunications capacity and increase market awareness and name
recognition.
 
  Leverage Extensive Management Experience. Global Crossing has assembled and
will continue to build a strong management team comprised of executives with
extensive operating experience in the telecommunications industry and the
undersea cable sector. For more information, see "Management."

                                 FINANCING PLAN
 
  As of September 30, 1998, we have incurred approximately $708.6 million of
the $750 million in total estimated costs for AC-1 (excluding upgrades). All
future costs excluding upgrades with respect to AC-1 are fully financed. We
estimate that the total cost of developing and deploying PC-1, MAC, PAC, PEC
and GAL is approximately $2,815 million (excluding costs of potential future
upgrades and the amounts capitalized with respect to the warrants (the "PCG
Warrants") issued pursuant to the Warrant Agreement, dated as of January 21,
1998, as amended), which is comprised of $1,200 million for PC-1, $330 million
for MAC, $475 million for PAC, $700 million for PEC and $110 million for GAL.
 
  On May 18, 1998, we consummated an offering (the "Senior Notes Offering")
pursuant to which we issued an aggregate of $800 million in principal amount of
notes (the "Senior Notes"). We utilized approximately $295 million of the net
proceeds of the Senior Notes Offering to refinance certain obligations incurred
as part of the initial financing of AC-1. The balance will be utilized to make
equity investments in certain of our systems and for general corporate
purposes.
 
  On August 13, 1998, Global Crossing Ltd., our parent, and certain of its
shareholders sold 24,150,000 shares of common stock (the "GCL Common Stock")
offered in concurrent offerings made in the United States, Canada and
internationally (the "GCL Stock Offerings"). We received approximately $392.1
million of the net proceeds from the GCL Stock Offerings in the form of a
capital contribution from our parent. We intend to use these proceeds as
follows: (i) to make investments in the Global Crossing Network, (ii) to make
minority investments in telecommunications companies and Internet service
providers, (iii) to fund our equity investment in GAL and (iv) for general
corporate purposes.

                     SUMMARY OF TERMS OF THE EXCHANGE OFFER
 
  The Exchange Offer relates to the exchange of up to $500,000,000 aggregate
liquidation preference of our outstanding 10 1/2% Senior Exchangeable Preferred
Stock due 2008 ("Old Preferred Stock") for up to an equal aggregate liquidation
preference of our 10 1/2% Senior Exchangeable Preferred Stock due 2008 (the
"Exchange Preferred Stock"), which has been registered under the Securities Act
of 1933. The shares of the Exchange Preferred Stock will be our obligations
governed by our bye-laws, as amended (the "Bye-laws"). The form and terms of
the shares of the Exchange Preferred Stock are identical in all material
respects to the form and terms of the shares of the Old Preferred Stock except:
 
  . that the shares of the Exchange Preferred Stock have been registered under
    the Securities Act,
 
  . that the shares of the Exchange Preferred Stock are not entitled to
    certain registration rights which are applicable to the shares of the Old
    Preferred Stock under a registration rights agreement, and
 
  . for certain contingent interest rate provisions.
 
  The shares of the Old Preferred Stock and the shares of the Exchange
Preferred Stock are together referred to herein as the "Preferred Stock." For
more information, see "Description of Preferred Stock."
 
The Exchange Offer..........  We are offering to exchange $100 liquidation
                              preference of Exchange Preferred Stock for each
                              $100 liquidation preference of Old Preferred
                              Stock.
 
                              As of the date hereof, $500,000,000 in aggregate
                              liquidation preference of Old Preferred Stock is
                              outstanding. The Old Preferred Stock was
                              originally issued in a private placement. As a
                              condition to the purchase of the Old Preferred
                              Stock, the initial purchasers required that we
                              make a registered offer to exchange the Old
                              Preferred Stock for other securities
                              substantially similar to the Old Preferred Stock.
                              We are making this Exchange Offer to satisfy this
                              contractual obligation.

                              believe that Exchange Preferred Stock issued

                              provide that the holders of a majority of the
                              then outstanding shares of Exchange Preferred
                              Stock, voting as a separate single class, will be

                              all other voting rights triggering events have
                              been cured or waived.
 
                              In addition, holders of at least two-thirds of
                              the then outstanding Exchange Preferred Stock
                              must approve certain changes that would be
                              materially adverse to their rights.

- --------
 (1) Includes a charge for the Advisory Services Agreement Termination on June
     30, 1998. See "Certain Transactions." GCL acquired the rights on behalf of
     the Company of those entitled to fees payable under the Advisory Services
     Agreements in consideration for the issuance of GCL Common Stock having an
     aggregate value of $135 million and the cancellation of approximately $2.7
     million owed to GCL under a related advance agreement. As a result of this
     transaction, the Company has recorded a non-recurring charge in the
     approximate amount of $137.7 million during the nine months ended
     September 30, 1998. Also, during the nine months ended September 30, 1998,
     we recognized $8.2 million from a total of $22.9 million of stock-related
     expense relating to stock options issued during such period, which entitle
     the holders to purchase GCL Common Stock. The remaining $14.7 million will
     be recognized as follows: $1.7 million in the fourth quarter of 1998, $6.8
     million in 1999, $5.0 million in 2000 and $1.2 million in 2001.
 (2) Reflects income taxes on profits earned during the three and nine months
     ended September 30, 1998 attributable to both United States and other
     foreign jurisdictions. A significant portion of our operating losses have
     been incurred in non-taxable jurisdictions and therefore these operating
     losses cannot be applied to offset our future taxable earnings.
 (3) On May 18, 1998, a portion of the proceeds from the issuance of the Senior
     Notes was used to repurchase the 12% Senior Notes Due 2004 ("GTH Senior
     Notes") of Global Telesystems Holdings Ltd., a direct subsidiary of the
     Company. We recognized an extraordinary loss of $19.7 million on this
 
                                       14
<PAGE>
 
     repurchase, comprising a repurchase premium of approximately $9.8 million
     and a write-off of approximately $9.9 million of unamortized deferred
     financing costs.
 (4) The holders of the 14% senior increasing rate redeemable exchangeable
     preference shares of GTH (the "GTH Preference Shares") were entitled to
     receive cumulative, compounding dividends at an initial annual rate of
     14%. Preference share dividends include cumulative 14% dividends and
     amortization of the discount and issuance costs. Effective June 17, 1998,
     we used proceeds from the Senior Notes to redeem all outstanding GTH
     Preference Shares. All dividends prior to the redemption had been paid
     through the issuance of additional preference shares and charged against
     additional paid-in-capital.
 (5) As a result of the redemption of the GTH Preference Shares, we incurred a
     one time $34.1 million charge against additional paid-in-capital. The
     charge was comprised of: (i) a $15.9 million charge for the redemption
     premium and (ii) a write-off of $18.2 million of unamortized discount and
     unamortized deferred financing costs.
 (6) The majority of Cash and Restricted Cash is comprised of proceeds from the
     issuance of the Senior Notes and from the GCL Stock Offerings contributed
     to the Company.
 (7) Construction in Progress and Capacity Available for Sale includes direct
     and indirect expenditures for construction of AC-1 and other systems and
     is stated at cost. Includes costs incurred under (i) the construction
     contracts; (ii) advisory, consulting and legal fees; (iii) interest
     (including amortization of debt issuance costs incurred during the
     construction phase); and (iv) other costs necessary for developing AC-1
     and other systems. Additionally, GCL granted the PCG Warrants to Pacific
     Capital Group, Inc. ("PCG"), a shareholder of GCL, for the PC-1, MAC and
     PAC systems and related rights. The $275.3 million value of the GCL Common
     Stock issued under the PCG Warrants was contributed to the Company and
     allocated to Construction in Progress in the amount of $112.2 million and
     as Investment in Pacific Crossing Ltd. ("PCL") in the amount of $163.1
     million.
 (8) Includes $163.1 million as of September 30, 1998, as described above,
     representing the value of the PCG Warrants applicable to Pacific Crossing
     Ltd., less $1.0 million representing the Company's equity share in the
     loss of PCL for the nine months ended September 30, 1998.
 (9) Not including current portion of borrowings under the AC-1 Credit Facility
     of $27.4 million and $33.3 million current portion of obligations under
     inland service agreements and capital leases.
(10) The December 31, 1997 amount is comprised of (i) $100 million of GTH
     Preference Shares originally issued, plus (ii) $9.8 million of GTH
     Preference Shares issued as dividends thereon, less (iii) $19.2 million
     reflecting the unamortized discount and issue costs associated therewith.
     The Company redeemed all of the outstanding GTH Reference Shares effective
     as of June 17, 1998.
(11) Assumes full completion of AC-1, PC-1, MAC, PAC, PEC and GAL based upon
     our current estimates, including anticipated financing costs. See "Risk
     Factors--Risks Related to Completing our Cable Systems" and "Risk of Error
     in Forward-Looking Statements."

                                  RISK FACTORS
 
  Before you participate in the Exchange Offer, you should be aware that there
are various risks, including the ones listed below. You should carefully
consider these risk factors, as well as the other information contained in this
prospectus, in evaluating your participation in the Exchange Offer.
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD PREFERRED STOCK
 
  We will issue Exchange Preferred Stock in exchange for the Old Preferred
Stock pursuant to the Exchange Offer only following the satisfaction of the
procedures and conditions set forth in "The Exchange Offer--Procedures for
Tendering Shares of Old Preferred Stock." Such procedures and conditions
include timely receipt by the Exchange Agent of such shares of Old Preferred
Stock, and of a properly completed and duly executed Letter of Transmittal.
Shares of Old Preferred Stock which you do not tender or we do not accept will,
following the Exchange Offer, continue to be restricted securities and you may
not offer or sell them except pursuant to an exemption from, or in a
transaction not subject to, the Securities Act of 1933 and applicable state
securities law.
 
  Any shares of Old Preferred Stock tendered and exchanged in the Exchange
Offer will reduce the aggregate principal amount of the Old Preferred Stock
outstanding. Following the Exchange Offer, if you did not tender your shares of
Old Preferred Stock you generally will not have any further registration
rights, and such shares of Old Preferred Stock will continue to be subject to
certain transfer restrictions. Accordingly, the liquidity of the market for
such shares of Old Preferred Stock could be adversely affected. The shares of
Old Preferred Stock are currently eligible for sale pursuant to Rule 144A
through the Private Offerings, Resale and Trading through Automated Linkages
("PORTAL") market of the National Association of Securities Dealers, Inc.
Because we anticipate that most holders of Old Preferred Stock will elect to
exchange such shares of Old Preferred Stock, we anticipate that the liquidity
of the market for any shares of Old Preferred Stock remaining after the
consummation of the Exchange Offer may be substantially limited.
 
LACK OF PUBLIC MARKET FOR THE SECURITIES
 
  The shares of Exchange Preferred Stock will be new securities for which there
currently is no established trading market. We do not intend to apply for
listing of the Exchange Preferred Stock on a national securities exchange or
automatic quotation system. Although the initial purchasers of the Old
Preferred Stock have informed us that they currently intend to make a market in
the Exchange Preferred Stock, the initial purchasers are not obligated to do
so, and any such market making may be discontinued at any time without notice.
The liquidity of any market for the shares of Exchange Preferred Stock will
depend upon the number of holders of the Exchange Preferred Stock, the interest
of securities dealers in making a market in the Exchange Preferred Stock and
other factors. Accordingly, there can be no assurance as to the development or
liquidity of any market for the shares of Exchange Preferred Stock. If an
active trading market for the shares of Exchange Preferred Stock does not
develop, the market price and liquidity of the shares of Exchange Preferred
Stock may be adversely affected. If the shares of Exchange Preferred Stock are
traded, they may trade at a discount from their initial offering price,
depending upon prevailing interest rates, the market for similar securities,
our financial performance and certain other factors. The liquidity of, and
trading markets for, the shares of Exchange Preferred Stock also may be
adversely affected by general declines in the market for payment-in-kind
preferred stock. Such declines may adversely affect the liquidity of, and
trading markets for, the shares of Exchange Preferred Stock, independent of our
financial performance or prospects.
 
  Historically, the market for payment-in-kind preferred stock has been subject
to disruptions that have caused substantial volatility in the prices of
securities similar to the Exchange Preferred Stock. There can be no assurance
that the market, if any, for the shares of Exchange Preferred Stock will not be
subject to similar disruptions. Any such disruptions may have an adverse effect
on the holders of the Exchange Preferred Stock.

LIMITED OPERATING HISTORY
 
  Global Crossing was organized in March 1997 and has a limited operating
history. Our financial information relates principally to a period in which we
were constructing and developing AC-1 and, until June 1998, had minimal
revenues and operating costs. Despite recognizing approximately $218.9 million
in revenues, we have incurred a net loss applicable to common shareholder of
approximately $169.0 million for the period from March 19, 1997 (date of
inception) through September 30, 1998, due primarily to the termination of
certain advisory services agreements, awards under our Stock Incentive Plan,
the extraordinary loss on the retirement of the GTH Senior Notes and the
redemption of GTH Preference Shares. Global Crossing has financed its net
losses, debt service, capital expenditures and other cash needs to date through
the proceeds of sales of common and preferred equity and the issuance of debt,
including non-recourse indebtedness of Atlantic Crossing Ltd., PCL and Mid-
Atlantic Crossing Ltd. In addition, we will require substantial additional
capital in order to carry out our business plan. For more information, see "--
Substantial Future Capital Requirements."
 
  Our success will depend substantially on sales of capacity on our systems. We
have been marketing and selling capacity primarily on AC-1 which has resulted
in executed capacity purchase agreements and inland capacity purchase
agreements as of September 30, 1998 to purchase capacity totaling $767 million,
including related sales of terrestrial capacity. We cannot be certain that we
will continue to be successful in selling capacity on AC-1 or our other systems
under development. Additionally, we cannot be certain that we will be able to
realize our business plan. Furthermore, even if we realize our plan, we still
may not be able to sustain operating profitability or generate sufficient cash
flow to service our indebtedness. For more information, see "--Sales of
Capacity; Realization of Other Revenues," "--Termination of Capacity Purchase
Agreements," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business."
 
LEVERAGE
 
  We have incurred a high level of debt. As of September 30, 1998, we had a
total of $1,328 million of total liabilities, including approximately $1,213
million in senior indebtedness, of which $365 million was secured. In addition,
PCL has entered into a $850 million non-recourse credit facility with respect
to PC-1, under which as of September 30, 1998, PCL had incurred $200 million of
indebtedness. Furthermore, in November 1998, Mid-Atlantic Crossing Ltd. entered
into a $260 million non-recourse credit facility with respect to MAC. We have
also entered into a $300 million commitment letter for project financing for
PAC. For more information, see "Description of Certain Indebtedness."
 
  The amount of our debt could have important consequences for our future,
including, among other things:
 
  .  restrictive debt covenants may impair our ability to pay cash dividends
     or make required redemption payments on the Preferred Stock,
 
  .  cash from operations may be insufficient to meet the principal and
     interest on our indebtedness, including the Exchange Notes, as they
     become due,
 
  .  payments of principal and interest on borrowings may leave us with
     insufficient cash resources for our operations, and
 
  .  restrictive debt covenants may impair our ability to obtain additional
     financing.
 
  For more information see "Description of Certain Indebtedness."
 
  Our ability to repay our debt depends upon a number of factors, many of which
are beyond our control. In addition, we rely on dividends, loan repayments and
other intercompany cash flows from our subsidiaries to repay our obligations.
Our operating subsidiaries intend to enter into various credit arrangements.
Accordingly, once they enter into these credit arrangements, the payment of
dividends from our operating subsidiaries and the making and repayments of
loans and advances will become subject to statutory, contractual and other
restrictions.
 
                                       17
<PAGE>
 
  In addition, if we are unable to generate sufficient cash flow to meet our
debt service requirements, we may have to renegotiate the terms of our long
term debt. There can be no assurance that we would be able to successfully
renegotiate such terms or refinance our indebtedness when required or that
satisfactory terms of any such refinancing would be available. If we were not
able to refinance our indebtedness or obtain new financing under these
circumstances, we would have to consider other options, such as:
 
  .sales of certain assets to meet our debt service obligations,
 
  .sales of equity,
 
  .negotiations with our lenders to restructure applicable indebtedness, or
 
  .other options available to us under applicable law.
 
SUBSTANTIAL FUTURE CAPITAL REQUIREMENTS
 
  We will require substantial capital investment to implement our business
plan. Because we anticipate that each of our systems will require separate
financing in addition to our equity investment in each system, we intend to
raise additional non-recourse debt or equity capital at the system level to
meet these financing requirements. We currently estimate that our capital
resources, together with the additional capital that we intend to raise at the
system level, will be sufficient to fund our currently planned systems. If we
are unable to fund the development of our systems, our business, financial
condition and results of operations will be materially adversely affected. For
more information, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
RISKS RELATED TO COMPLETING OUR CABLE SYSTEMS
 
  Our ability to achieve our strategic objectives will depend in large part
upon the successful, timely and cost-effective completion of our planned cable
systems as well as on achieving substantial capacity sales on these systems
once they become operational. The construction of our systems will be affected
by a variety of factors, uncertainties and contingencies, many of which are
beyond our control. There can be no assurance that each of these systems will
be completed at the cost and in the time frame currently estimated by Global
Crossing, or even at all. Although we will be awarding contracts for
construction of our systems to certain suppliers who in most cases are expected
to be bound by a fixed-price construction cost schedule, and to provide
guarantees in respect of completion dates and system design specifications,
there can be no assurance that the actual construction costs or the time
required to complete these systems will not exceed our current estimates. Such
circumstances could have a material adverse effect on our results of operations
or financial condition. For more information, see "Business--Suppliers."
 
  Our successful completion of our cable systems will depend, among other
things, upon:
 
  .our ability to manage their construction effectively,
 
  .our ability to obtain all construction permits and licenses,
 
  .third-party contractors performing their obligations on schedule, and
 
  .our ability to enter into favorable construction contracts with a limited
  number of suppliers.
 
  Failure with respect to any of the foregoing may significantly delay or
prevent completion of one or more of our systems, which could have a material
adverse effect on our business, financial condition and results of operations.
 
HOLDING COMPANY STRUCTURE; EFFECTIVE SUBORDINATION OF THE SECURITIES
 
  We are a holding company and derive substantially all of our revenues from
our subsidiaries. We intend to lend or contribute all of the net proceeds from
the offering of the Old Preferred Stock to certain of our subsidiaries. We will
rely on
 
                                       18
<PAGE>
 
payments from our subsidiaries to be able to meet our obligations. We will not
be able to pay out cash dividends on the Preferred Stock, redeem the Preferred
Stock or pay interest and principal on the Exchange Notes or redeem the
Exchange Notes without receiving dividends from our subsidiaries. Our
subsidiaries' ability to make such payments to us will be subject to the
availability of sufficient cash. Some subsidiaries' abilities to pay dividends
to us may also be subject to restrictive covenants in existing or future debt
agreements.
 
SUBORDINATION
 
  The Exchange Notes, if and when issued, will rank behind all of our existing
indebtedness (other than trade payables) and all of our future borrowings
(other than trade payables), except any future indebtedness that expressly
provides that it ranks equal with, or subordinated in right of payment to, the
Exchange Notes. As a result, upon any distribution to our creditors in a
bankruptcy, liquidation or reorganization or similar proceeding relating to us
or our property, the holders of senior debt of our Company will be entitled to
be paid in full in cash before any payment may be made with respect to the
Exchange Notes.
 
  In addition, all payments on the Exchange Notes will be blocked in the event
of a payment default on designated senior debt and may be blocked for up to 179
of 360 consecutive days in the event of certain non-payment defaults on senior
debt.
 
  In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to our Company, holders of the Exchange Notes will
participate with trade creditors and all other holders of subordinated
indebtedness of the Company in the assets remaining after we have paid all of
the senior debt. However, because the indenture will require that amounts
otherwise payable to holders of the Exchange Notes in a bankruptcy or similar
proceeding be paid to holders of senior debt instead, holders of the Exchange
Notes may receive less, ratably, than holders of trade payables in any such
proceeding. In any of these cases, we may not have sufficient funds to pay all
of our creditors and holders of Exchange Notes may receive less, ratably, than
the holders of senior debt.
 
  Assuming we had completed the offering of the Old Preferred Stock on
September 30, 1998, the Exchange Notes would have been subordinated to $1,213
million of senior debt. We will be permitted to borrow substantial additional
indebtedness, including senior debt, in the future under the terms of the
indenture.
 
SALES OF CAPACITY; REALIZATION OF OTHER REVENUES
 
  Our ability to achieve our business objectives will also depend in large part
upon our sales and marketing capabilities. Through our wholly-owned subsidiary,
Global Crossing International, Ltd. ("GCI"), we have assembled a dedicated
sales and marketing force. We depend upon the ability of such employees to
effectively market and sell capacity. We cannot be certain that we will be able
to effectively sell capacity on our cable systems. If we are unable to
effectively sell capacity on our cable systems, our results of operations could
be materially affected.
 
  We intend to grow revenues and profits by:
 
  .upgrading capacity on our planned systems,
 
  .developing additional undersea cable projects,
 
  .developing or purchasing additional terrestrial fiber capacity, and
 
  .introducing new services.
 
  For more information, see "Business." If we are unable to effect these
upgrades, develop additional cable projects or develop or obtain additional
terrestrial capacity, our business, financial condition and results of
operations could be adversely affected.

TERMINATION OF CAPACITY PURCHASE AGREEMENTS
 
  Under all of our capacity purchase agreements for AC-1, the customer may
terminate the agreement for capacity on any segment other than the United
States-United Kingdom segment if the ready for service date for the applicable
segment has not occurred by June 30, 1999. Furthermore, under some AC-1
capacity purchase agreements, the customer will receive a refund on the United
States-United Kingdom segment if the ready for service date for the full AC-1
system has not occurred by June 30, 1999. In addition, under some AC-1
capacity purchase agreements, the customer may terminate the agreement if we
do not obtain and hold certain governmental authorizations, approval,
consents, licenses and permits. Capacity purchase agreements for our other
systems may contain similar provisions. If a substantial number of capacity
purchase agreements are terminated for any of the foregoing reasons, our
business, financial condition and results of operations could be adversely
affected. For more information, see "Business--Sales and Marketing" and "--
Summary of Principal Terms of Standard Contractual Documentation."
 
COMPETITION
 
  The international telecommunications industry is highly competitive. We face
competition from existing and planned systems along each of our planned
routes. We also compete with satellite providers, including existing
geosynchronous satellites and low-earth orbit systems now under construction.
On certain routes, we compete against terrestrial cable systems. We compete
primarily on the basis of price, availability, transmission quality and
reliability, customer service and the location of our systems. Traditionally,
carriers have made substantial long term investments in ownership of cable
capacity. This has meant that low price and high-end service have not been
determining factors in such carriers' decisions to purchase additional
capacity. Accordingly, there can be no assurance that we will be able to
compete successfully against systems to which prospective customers have made
long term commitments.
 
  The routes underlying our systems are currently served by several undersea
cables, terrestrial systems as well as satellites. Primary future sources of
competition for Global Crossing may result from, among others:
 
  (1) TAT-14, a transatlantic cable system which is being developed by its
      consortium members,
 
  (2) Gemini, a transatlantic cable system being operated and marketed by MCI
      WorldCom, Inc., and Cable & Wireless PLC,
 
  (3) China-US, a transpacific system being developed as a "private cable
      system" by fourteen large carriers, including SBC Communications Inc.,
      MCI WorldCom, Inc, AT&T Corp. and Sprint Corp., most of whom have
      traditionally sponsored consortium cables, and
 
  (4) the Japan-US Cable Network, a transpacific system being developed by a
      consortium of major telecommunications carriers including MCI WorldCom,
      Inc., AT&T Corp., KDD, Nippon Telegraph & Telephone Corp., Cable &
      Wireless PLC and GTE Corporation.
 
Other regional and global systems are being considered by developers,
including Project Oxygen, a global system being evaluated by CTR Group, Ltd.
We believe that the other transatlantic systems will directly compete with AC-
1 and may reduce customer demand on AC-1. We believe that the other planned
transpacific systems will not satisfy the demand for capacity between the
United States and Japan and that there is currently enough demand projected to
accommodate all such systems. Nevertheless, the other planned transpacific
systems will receive commitments for capacity that PC-1 could have received in
their absence. In addition, we may face competition from existing and planned
regional undersea cable systems and satellites on our MAC and PAC routes,
where entrants are vying for purchases from a small but rapidly growing
customer base. Furthermore, we will face competition on PEC from various
carriers who are either currently building or
 
                                      20

planning to build trans-European network assets. For more information, see "--
Rapid Growth in a Changing Industry; Pricing Uncertainties" and "Business--
Competition."
 
RELATIONSHIP WITH PRINCIPAL SHAREHOLDERS; CONFLICTS OF INTEREST
 
  As of September 30, 1998, Pacific Capital Group, Inc. ("PCG") had a 23.51%
beneficial ownership interest in GCL. Global Crossing and GCL have entered into
various transactions with PCG and have assumed the on-going development of PC-
1, PAC and MAC from an affiliate of PCG. Mr. Gary Winnick, Co-Chairman of GCL's
Board of Directors, controls PCG and its subsidiaries. In addition, several
other officers and directors of GCL and the Company are affiliated with PCG.
Furthermore, through an affiliate, Canadian Imperial Bank of Commerce ("CIBC")
had a 22.39% beneficial ownership interest in GCL as of September 30, 1998. An
affiliate of CIBC was an initial purchaser of the Old Preferred Stock, was an
underwriter in the GCL Stock Offerings, was an initial purchaser in the Senior
Notes Offering, and CIBC and its affiliates have also entered into certain
financing transactions with Global Crossing in connection with the development
and construction of its systems. Several members of GCL's Board of Directors
are affiliated with CIBC. For more information, see "Management," "Principal
Shareholders," and "Certain Transactions."
 
  Upon completion of the GCL Stock Offerings, PCG and CIBC collectively
beneficially owned 46.46% of the outstanding GCL Common Stock. Accordingly, PCG
and CIBC may be able to determine the vote on matters submitted to a vote of
the stockholders of GCL, including the election of directors of GCL.
 
  Certain of GCL's officers and directors also serve as officers and directors
of other companies. Additionally certain of GCL's officers and directors are
active investors in the telecommunications industry. For more information, see
"Management." Service as GCL's director or officer and as a director or officer
of another company could create conflicts of interest when the director or
officer is faced with decisions that could have different implications for GCL
or Global Crossing and the other company. A conflict of interest could also
exist with respect to allocation of time and attention of persons who are
officers of both GCL and another company. The pursuit of these other business
interests could distract these officers and directors from pursuing
opportunities on GCL's behalf. Such conflicts of interest could have a material
adverse affect on our financial condition.
 
TRANSITION FROM MANAGEMENT TO OPERATING COMPANY
 
  The transition from a development stage company to an operating company
places significant demands on our management and operations. We are in the
process of expanding the management and operational capabilities necessary for
this transition.
 
  Our ability to manage this transition successfully will depend on, among
other things:
 
  .  expanding, training and managing our employee base, including
     attracting, retaining and motivating highly skilled personnel,
 
  .  taking over or outsourcing our customer interface and operations,
     administrative and maintenance systems,
 
  .procuring terrestrial capacity to provide connectivity to inland cities,
  and
 
  .controlling expenses.
 
  There can be no assurance that we will succeed in developing all or any of
these capabilities, and any failure to do so could have a material adverse
effect on our results of operations. For more information, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Management."
 
                                       21

RAPID GROWTH IN A CHANGING INDUSTRY; PRICING UNCERTAINTIES
 
  Part of our strategy is to construct several cable systems in a short time
frame in order to take advantage of the supply and demand imbalance that
currently exists and is projected to exist in the global marketplace. Each of
our currently announced systems is expected to be operational between now and
2000. As a result of this aggressive strategy, we are experiencing rapid
expansion and expect it to continue for the foreseeable future. This growth has
increased our operating complexity. At the same time, the international
telecommunications industry is changing rapidly due to, among other things:
 
  .the easing of regulatory constraints,
 
  .the privatization of established carriers,
 
  .the expansion of telecommunications infrastructure,
 
  .the globalization of the world's economies, and
 
  .the changing technology for wireless and satellite communication.
 
  Much of our planned growth is predicated upon the growth in demand for
international telecommunications capacity. There can be no assurance that such
anticipated demand growth will occur.
 
  The fiber optic cable transmission industry has experienced significant per
circuit price declines resulting from technological advances in fiber optic
technology. Recent changes in technology caused prices for circuits to go down
even further. If there is less demand than we project or a bigger drop in
prices per circuit than we project, there could be a material adverse effect on
our business, financial condition and results of operations. There can be no
assurance, even if our projections with respect to such factors are realized,
that we will be able to implement our strategy or that our strategy will be
successful in the rapidly evolving telecommunications market.
 
RAPID TECHNOLOGICAL CHANGE
 
  The telecommunications industry is subject to rapid and significant changes
in technology. For instance, recent technological advances permit substantial
increases in the transmission capacity of both new and existing fiber. The
introduction of new products or the emergence of new technologies also may
reduce the cost and increase the supply of certain services similar to those
provided by Global Crossing. While we believe that being the first to construct
and to market cable systems with significant capacity on certain routes may
stop competitors from overbuilding in those situations, we cannot predict the
behavior of potential competitors who might otherwise build a system even if it
would be uneconomical. We believe that for the foreseeable future, technology
changes will neither materially affect the continued use of fiber optic cable
nor materially hinder our ability to deploy the state-of-the-art technology.
However, we cannot predict the effect of technological changes on our
operations and such changes could have a material effect on our business,
financial condition and results of operations.
 
OPERATIONS RISKS
 
  Each of our systems will be subject to the risks inherent in a large-scale,
complex fiber optic telecommunications system. The operations, administration,
maintenance and repair of these systems requires the coordination and
integration of sophisticated and highly specialized hardware and software
technologies and equipment located throughout the world. There can be no
assurance that, even if built to specifications, our systems will function as
expected in a cost-effective manner. The failure of the hardware or software to
function as required could render a cable system unable to perform at design
specifications.
 
  AC-1 has, and each of our other systems are expected to have, a design life
of not less than 25 years; however, there can be no assurance of the actual
useful life of any of these systems. A number of factors will affect the useful
life of each of our systems, including, among other things:
 
  .quality of construction,
 
                                       22
<PAGE>
 
  .unexpected deterioration, and
 
  .technological or economic obsolescence.
 
  Failure of any of our systems to operate for its full design life could have
a material adverse effect on our business, financial condition and results of
operations.
 
DEPENDENCE ON KEY PERSONNEL
 
  Our future success depends on the skills, experience and efforts of certain
of the officers and key technical and sales employees of GCL and of Global
Crossing. Some of these officers and employees are new to Global Crossing. We
cannot be certain that we will be able to integrate new management into our
existing operations. In addition, competition for these individuals is intense,
and we may not be able to attract, motivate and retain highly skilled qualified
personnel. We do not have "key person" life insurance policies covering any of
our employees. For more information, see "Management--Employment Contracts and
Termination of Employment and Change-in-Control Arrangements."
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  We will derive substantial revenues from international operations. We intend
to have substantial physical assets in several jurisdictions along the routes
of our planned systems.
 
  Accordingly, our business is subject to certain risks inherent in
international operations. These risks include:
 
  .political and economic conditions,
 
  .unexpected changes in regulatory environments,
 
  .exposure to different legal standards, and
 
  .difficulties in staffing and managing operations.
 
  We have not experienced any material adverse effects with respect to our
foreign operations arising from such factors. However, problems associated with
such risks could arise in the future. Finally, managing operations in multiple
jurisdictions will place further strain on our ability to manage our overall
growth.
 
FOREIGN EXCHANGE; EXCHANGE CONTROLS
 
  We will invoice the majority of our sales in U.S. dollars, and the majority
of our customers will incur maintenance and other obligations denominated in
U.S. dollars. Many of our actual and prospective customers derive their
revenues in currencies other than U.S. dollars. Such customers will have to pay
more money for the same maintenance if their currencies devalue relative to the
U.S. dollar. Furthermore, such customers may be or may become subject to
exchange control regulations which might restrict or prohibit the conversion of
their revenue currencies into dollars. We then may be unable to receive payment
because the customer may not have any U.S. dollars available to it. We cannot
be certain that the occurrence of any such factors will not have a material
adverse effect on our business, financial condition and results of operations.
 
EFFECT OF GOVERNMENT REGULATION
 
  We will be required to obtain and maintain various permits, licenses and
other authorizations in both the United States and in foreign jurisdictions
where our cables land and exist. In particular, undersea cable landing or
similar licenses will be required in many of the jurisdictions where Global
Crossing's systems will land and exist. These licenses are typically issued for
a term of years, subject to renewal. Moreover, these licenses may subject our
business and operations to varying forms of regulation, which could change over
the course of time.
 
                                       23
<PAGE>
 
If we fail to obtain or renew a license or if there is a material change in the
nature of the regulation to which we are subject, there could be a material
adverse effect on our business, financial condition and results of operations.
In addition, political developments and national and locals laws may affect our
international operations. Specifically, we must obtain construction and
operating licenses during the construction phase of each of our cable systems.
Although Global Crossing intends that the construction contracts for each of
its cable systems will impose the burden of acquiring and maintaining
construction licenses and permits on the contractor for each of such systems,
there can be no assurance that such contractor will successfully obtain such
permits and licenses. If we or the contractor fails to obtain or maintain any
construction or operating license, there could be a material adverse effect on
our business, financial condition and results of operations. For more
information, see "Business--Regulation."
 
DEPENDENCE ON THIRD PARTIES
 
  We depend and will continue to depend upon third parties to:
 
  .construct systems and provide equipment,
 
  .provide access to certain origination and termination points of our
  systems in various countries,
 
  .construct and operate landing stations in certain countries,
 
  .acquire rights of way,
 
  .provide terrestrial capacity to our customers through contractual
  arrangements, and
 
  .act as joint venture participants with regard to PC-1, GAL and other
  possible future systems.
 
  There can be no assurance that such third parties will perform their
contractual obligation or that they will not be subject to political or
economic events which may have a material adverse effect on our business,
financial condition and results of operations.
 
RISK OF ERROR IN FORWARD-LOOKING STATEMENTS
 
  We have included "forward-looking statements" throughout this prospectus.
These statements describe our attempt to predict future occurrences. We use the
words "believes," "anticipates," "expects," and similar expressions to identify
forward-looking statements. Forward-looking statements are subject to a number
of risks, assumptions and uncertainties, such as:
 
  .  risks associated with our ability to complete our systems within
     currently estimated time frames and budgets,
 
  .  risks associated with our ability to sell capacity on our systems,
 
  .  risks associated with our successful transition from a system
     development company to an operating company, and
 
  .  risks associated with our ability to effectively compete in a rapidly
     evolving and price competitive marketplace.
 
  This list is only an example of some of the risks, uncertainties and
assumptions that may affect our forward-looking statements. If any of these
risks or uncertainties materialize (or fail to materialize), or if the
underlying assumptions prove incorrect, actual results may differ materially
from those projected in the forward-looking statements. We do not intend to
update or revise any forward-looking statements included in this prospectus to
reflect future events. Factors that could cause actual results to differ
materially are those set forth in this section of the prospectus. You should
carefully read this section before making any decision to purchase these
Securities.
 
                                       24

COVENANT RESTRICTIONS
 
  The terms of the Exchange Preferred Stock and the New Exchange Notes will
impose certain operating and financial restrictions on us and our Restricted
Subsidiaries. These restrictions will significantly limit or prohibit, among
other things, our ability and our Restricted Subsidiaries' ability to:
 
  . 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 or acquisitions.
 
These restrictions could also limit our ability and our Restricted
Subsidiaries' ability to:
 
  . effect future financings,
 
  . make needed capital expenditures,
 
  . withstand a future downturn in our business or the economy in general, or
 
  . otherwise conduct necessary corporate activities.
 
  Our ability and our Restricted Subsidiaries' ability to comply with the
covenants and restrictions contained in the Bye-laws or the Indenture may be
affected by events beyond our control, including prevailing economic and
financial concerns. If we or our Restricted Subsidiaries fail to comply with
these restrictions, it could lead to a default under the terms of the Preferred
Stock or the Exchange Notes. In addition, in such circumstances we and our
Restricted Subsidiaries may not be able to meet our respective debt service
obligations. In the event of a default, holders of the Preferred Stock or the
Exchange Notes could elect to declare all of the indebtedness to be due and
payable together with accrued and unpaid interest. In such event, a significant
portion of our and our Restricted Subsidiaries' other indebtedness may become
immediately due and payable and there can be no assurance that we and our
Restricted Subsidiaries would be able to make such payments or borrow
sufficient funds from alternative sources to make any such payment. See
"Description of Preferred Stock--Certain Covenants" and "Description of
Exchange Notes--Certain Covenants."
PURCHASE OF SECURITIES UPON A CHANGE OF CONTROL
 
  The terms of the Preferred Stock and the Exchange Notes will require us to
make an offer to purchase the Securities upon the occurrence of a Change of
Control (if we do not exercise our rights to redeem the Preferred Stock in
full) at a purchase price equal to 101% of the liquidation preference of the
Preferred Stock or the principal amount of the Exchange Notes, plus accumulated
and unpaid dividends at the time of purchase or interest to the date of
purchase. Prior to commencing such an offer to purchase, we would be required
to (i) repay in full all of our indebtedness that would prohibit the purchase
of the Securities or (ii) obtain any requisite consent to permit the purchase.
If we are unable to repay all of such indebtedness or are unable to obtain the
necessary consents, we will be unable to offer to purchase the Securities and
such failure will constitute a voting rights triggering event under the terms
of the Preferred Stock or an event of default under the terms of the Exchange
Notes. There can be no assurance that we will have sufficient funds available
at the time of any Change of Control to make any debt payment (including
purchases of Securities) as described above. See "Description of Preferred
Stock--Repurchase at the Option of Holders--Change of Control" and "Description
of Exchange Notes--Repurchase at the Option of Holders--Change of Control."
 
TAX MATTERS
 
  We believe that a significant portion of the income derived from our subsea
systems will not be subject to tax by any of (i) Bermuda, which currently does
not have a corporate income tax, or (ii) certain other countries in which we
conduct activities or in which our customers are located, including the United
States. However, we
 
                                       25
<PAGE>
 
base our belief 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. 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. We cannot be certain
that any of the foregoing factors would not have a material adverse effect on
our business, financial condition and results of operations. For more
information, see "Tax Considerations."
 
FOREIGN PERSONAL HOLDING COMPANY, PASSIVE FOREIGN INVESTMENT COMPANY,
CONTROLLED FOREIGN CORPORATION AND PERSONAL HOLDING COMPANY RULES
 
  It is possible that the Issuer or one of its non-United States subsidiaries
will be classified as a foreign personal holding company (an "FPHC") under the
United States Internal Revenue Code. If you are a United States Holder as
defined below and the Issuer or one of its non-United States subsidiaries is
classified as an FPHC, then you would be required to pay tax on your pro-rata
share of the Issuer's (or its relevant subsidiary's) undistributed FPHC income.
We intend to manage our affairs so as to attempt to avoid or minimize having
income imputed to United States Holders under these rules, to the extent such
management of our affairs is consistent with our business goals. However, there
can be no assurance that we will be successful in this endeavor.
 
  The Issuer believes that it is not a passive foreign investment company (a
"PFIC") and does not expect to become a PFIC in the future. However, there can
be no assurance in this regard. In addition, this belief is based, in part, on
the Issuer 's interpretations of existing law that the Issuer believes are
reasonable, but which have not been approved by any taxing authority. If the
Issuer were a PFIC and you are a United States Holder, then you could be liable
to pay tax at the then prevailing rates on ordinary income plus an interest
charge upon certain distributions by the Issuer or when you sell the Preferred
Stock at a gain. For more information, see "Tax Considerations."
 
  Furthermore, additional tax considerations would apply if the Issuer or any
of its affiliates were a controlled foreign corporation (a "CFC") or a personal
holding company (a "PHC"). For more information, see "Tax Considerations."

 (1) Includes a charge for the Advisory Services Agreement Termination on June
     30, 1998. See "Certain Transactions." GCL acquired the rights on behalf of
     the Company of those entitled to fees payable under the Advisory Services
     Agreements in consideration for the issuance of GCL Common Stock having an
     aggregate value of $135 million and the cancellation of approximately $2.7
     million owed to GCL under a related advance agreement. As a result of this
     transaction, the Company has recorded a non-recurring charge in the
     approximate amount of $137.7 million.
 
 (2) During each of the three and nine months ended September 30, 1998, the
     Company recognized $1.7 and $8.2 million, respectively, from a total of
     $22.9 million of stock-related expense relating to stock options issued
     during nine months ended September 30, 1998. The remaining $14.7 million
     will be recognized as follows: $1.7 million in the fourth quarter of 1998,
     $6.8 million in 1999, $5.0 million in 2000 and $1.2 million in 2001.
 
 (3) Reflects income taxes on profits earned during the nine months ended
     September 30, 1998 attributable to both United States and foreign
     jurisdictions. A significant portion of the Company's operating losses
     have been incurred in non-taxable jurisdictions and therefore these
     operating losses cannot be applied to future taxable earnings of the
     Company.
 
 (4) On May 18, 1998, a portion of the proceeds from the issuance of the Notes
     was used to repurchase the GTH Senior Notes. The Company recognized an
     extraordinary loss of $19.7 million on repurchase comprising a premium of
     approximately $9.8 million and a write-off of approximately $9.9 million
     of unamortized deferred financing costs.
 
 (5) The holders of GTH Preference Shares were entitled to receive cumulative,
     compounding dividends at an initial annual rate of 14%. Preference share
     dividends include cumulative 14% dividends and amortization of the
     discount and issuance costs. Effective June 17, 1998, the Company used
     proceeds from the Senior Notes to redeem all outstanding GTH Preference
     Shares. All dividends prior to the redemption had been paid through the
     issuance of additional preference shares and charged against additional
     paid-in-capital.
 
 (6) As a result of the redemption of the GTH Preference Shares, the Company
     incurred a one-time $34.1 million charge against additional paid-in
     capital. The charge was comprised of: (i) a $15.9 million charge for the
     redemption premium and (ii) a write-off of $18.2 of unamortized discount
     and unamortized deferred financing costs.

 (7) The majority of Cash and Restricted Cash is comprised of proceeds from the
     issuance of the Senior Notes and from the GCL Stock Offerings, contributed
     to the Company.
 
 (8) Construction in Progress and Capacity Available for Sale includes direct
     and indirect expenditures for construction of AC-1 and other Systems and
     is stated at cost. Includes costs incurred under (i) the construction
     contracts; (ii) advisory, consulting and legal fees; (iii) interest
     (including amortization of debt issuance costs incurred during the
     construction phase); and (iv) other costs necessary for developing AC-1.
     Additionally, GCL granted the PCG Warrants to PCG, a shareholder of GCL,
     for the PC-1, MAC and PAC systems and related rights. The $275.3 million
     value of the GCL Common Stock issued under the PCG Warrants was
     contributed to the Company and recorded as Construction in Progress in the
     amount of $112.2 million and Investment in Pacific Crossing Ltd. in the
     amount of $163.1 million.
 
 (9) Includes $163.1 million as of September 30, 1998, as described above,
     representing the value of the PCG Warrants applicable to Pacific Crossing
     Ltd., less $1.0 million representing the Company's equity share in the
     loss of Pacific Crossing Ltd. for the nine months ended September 30,
     1998.
 
(10) Certain contracts to acquire terrestrial capacity and certain capital
     leases require payments over a 25-year period. The amount shown reflects
     the present value of such payments, net of the $33.3 million ($30.2
     million as of December 31, 1997) current portion of such payments, which
     is included under "Current Liabilities."
 
(11) The December 31, 1997 amount is comprised of (i) $100 million of GTH
     Preference Shares originally issued, plus (ii) $9.8 million of GTH
     Preference Shares issued as dividends thereon, less (iii) $19.2 million
     reflecting the unamortized discount and issue costs associated therewith.
     The Company has redeemed all of the outstanding GTH Preference Shares
     effective as of June 17, 1998.
 
(12) Assumes full completion of AC-1, PC-1, MAC, PAC, PEC and GAL based upon
     current Company estimates, including anticipated financing costs. See
     "Risk Factors--Risks Related to Completing our Cable Systems" and "--Risk
     of Error in Forward-Looking Statements."
 
(13) For the purposes of this computation, earnings are defined as income
     (loss) before income taxes plus fixed charges. Fixed charges consist of
     interest expense (including amortization of deferred debt issuance costs)
     and the portion of rental expense that is representative of the interest
     factor (deemed to be one-third of minimum operating lease rentals).

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
Company's audited Consolidated Financial Statements and the notes thereto
contained in this prospectus.
 
OVERVIEW
 
  The Company is the world's first independent provider of global Internet and
long distance telecommunications facilities and services utilizing a network of
undersea and terrestrial digital fiber optic cable systems. The Company
commenced operations in March 1997, when it entered into a fixed price contract
with Tyco Submarine Systems Ltd. ("TSSL"), formerly AT&T Submarine Systems,
Inc., for the design, development, construction and installation of AC-1, and
obtained commitments for AC-1's initial financing. AC-1, the first of Global
Crossing's planned fiber optic cable systems, is designed to be a four fiber
pair system connecting (i) the United States to the United Kingdom, (ii) the
United Kingdom to The Netherlands and Germany, (iii) The Netherlands to Germany
and (iv) Germany to the United States. The first segment of AC-1, the United
States to United Kingdom route, was completed and commenced operations on May
26, 1998. The Company currently anticipates that the full AC-1 system will be
completed and commence operations by February 1999. See "Risk Factors--Risks
Related to Completing our Cable Systems."
 
  Until May 26, 1998, the Company was a development stage company and since its
inception, has been involved in the planning, financing, marketing,
organization, development, design and construction of the AC-1 system. In
addition, the Company has been engaged in the planning, developing and
financing of the five other planned systems currently under active development
by the Company (PC-1, MAC, PAC, PEC and GAL). The Company has also achieved a
number of significant milestones, including (i) the recruitment of experienced
professionals in undersea cable and telecommunications operations, (ii) the
signing of construction contracts on AC-1, PC-1, MAC and PAC, (iii) the
execution of the AC-1, PC-1 and MAC credit facilities and the execution of a
financing commitment with respect to PAC, (iv) the construction and activation
of the United States to United Kingdom segment of AC-1, (v) the issuance of an
aggregate of $800 million in principal amount of the Company's Senior Notes,
(vi) the initial public offering of GCL Common Stock by the Company's parent,
GCL and (vii) the execution of over $767 million of capacity purchase
agreements ("CPAs") and inland capacity purchase agreements ("ICPAs").
Effective May 26, 1998, the United States--United Kingdom segment of AC-1
achieved "ready-for-service" ("RFS") and the Company began recognizing revenue
from the sale of capacity. Accordingly, the Company is no longer a development
stage company.
 
  In March 1998, Global Crossing Ltd., LDC ("Old GCL"), a limited duration
company formed under the laws of the Cayman Islands, formed a wholly-owned
subsidiary in Bermuda known as Global Crossing Holdings Ltd. and contributed
its investment in Global Telesystems Holdings Ltd. to Global Crossing Holdings
Ltd. In April 1998, Global Crossing Holdings Ltd. changed its name to Global
Crossing Ltd. and formed the Issuer as a wholly-owned subsidiary. Global
Crossing Ltd. then contributed its investment in Global Telesystems Holdings
Ltd. to the Issuer. Prior to the GCL Stock Offerings, substantially all of the
shareholders of Old GCL exchanged their equity interests in Global Crossing
Ltd., LDC for GCL Common Stock of Global Crossing Ltd.
 
  The Company, together with other partners, formed a joint venture company,
PCL, which on April 21, 1998 entered into a contract with TSSL to construct the
PC-1 cable system. The estimated cost of the PC-1 system is approximately $1.2
billion (excluding potential future upgrades and amounts capitalized with
respect to the PCG Warrants) and will be financed through a $400 million equity
contribution by the joint venture partners and through borrowings under the
credit facility discussed below. PC-1 is an undersea fiber optic cable system
connecting California, Washington and two landing sites in Japan. The Company
has approximately a 58% economic interest in PCL, represented by a 50% direct
voting interest in PCL and, through an equity ownership interest in one of the
other joint venture partners, a further 8% economic non-voting interest. The
Company's funding commitment in respect of the $400 million of equity in PCL
totals $231 million, which is
 
                                       31
<PAGE>
 
proportional to its economic interest. PCL has obtained an $850 million senior
secured, non-recourse credit facility from certain lenders to finance the
remaining construction costs of the PC-1 system. The Company accounts for its
investment in PCL on an equity basis.
 
  Effective June 2, 1998, the Company, through its wholly-owned subsidiary
Mid-Atlantic Crossing Ltd. ("MACL"), entered into a contract with Alcatel
Submarine Networks ("Alcatel") for the construction of MAC, an undersea fiber
optic cable system connecting New York, the Caribbean and Florida. The
estimated costs of the MAC system is approximately $330 million (excluding
potential future upgrades and amounts capitalized with respect to the PCG
Warrants). This will be financed through a $110 million equity contribution
and through borrowings under a non-recourse credit facility. Effective
November 25, 1998, MACL obtained $220 million in non-recourse course project
financing from certain lenders to finance the initial construction costs of
MAC.
 
  Effective July 21, 1998, the Company, through its wholly-owned subsidiary
Pan American Crossing Ltd. ("PACL"), entered into a contract with TSSL to
construct PAC, an undersea fiber optic cable system connecting California with
two landing sites in Mexico, Panama and the Caribbean. The estimated costs of
the PAC system of approximately $475 million (excluding potential future
upgrades and amounts capitalized with respect to the PCG Warrants) will be
financed through a $175 million equity contribution and through borrowings
under a non-recourse credit facility. On July 21, 1998, PACL entered into a
commitment letter to obtain $300 million of non-recourse indebtedness.
 
  In October 1998, the Company announced its plans to build PEC, which upon
completion, will interconnect AC-1 and 18 European cities including London,
Paris, Amsterdam, Rotterdam, Antwerp, Brussels, Hamburg, Hanover, Dusseldorf,
Cologne, Frankfurt, Strasbourg and Copenhagen. The Company also has future
plans to connect additional European cities to the system. PEC is being
initially planned as a 7,200 km system with 24 to 72 fiber pairs. The Company
is currently negotiating with various parties for the construction of PEC and,
based on those negotiations we believe that the construction cost for the
system will be approximately $700 million.
 
  In December 1998, the Company announced its plans to build GAL, which will
among other things interconnect PC-1 and Tokyo and Osaka. GAL is being
initially planned as a 1,200 km system. The Company is currently negotiating
with various parties for the construction of GAL and, based on those
negotiations, the Company believes that the construction cost for the system
will be approximately $110 million.
 
  Sales of capacity by the Company on its cable systems are effected through
CPAs pursuant to which the Company's customers obtain an indefeasible right of
use ("IRU") for a certain number of circuits. Each IRU entitles the customer
to the use of the related capacity for a period ending 25 years after the RFS
date for the related system. Global Crossing also sells terrestrial capacity
through ICPAs, linking certain of the Company's landing stations with major
cities in order to provide city-to-city connectivity to its customers.
Terrestrial capacity purchased by the Company through Inland Services
Agreements ("ISAs") from the owners of terrestrial cable systems is resold by
the Company to its customers through ICPAs. The CPAs and ICPAs generally
provide for a cash deposit upon execution, followed by full payment upon
activation of the related capacity pursuant to the terms of the agreements.
The Company also offers customers multi-year CPAs for capacity across the
entire Global Crossing Network at tiered pricing.
 
  The Company's basic pricing structure currently provides for volume-based
discounts to its customers as well as discounts for early purchases on a
particular system. Customers are generally provided options in their CPAs to
purchase additional capacity in the future at prices which reflect the
aggregate purchases made by such customers. Consequently, the prices under
such options in the future are often lower than the current price paid by such
customers for their initial capacity.
 
                                      32
<PAGE>
 
REVENUES
 
  Revenues from CPAs and ICPAs are recognized in the period during which (i)
the purchaser obtains the right to use the capacity, which can only be
suspended following a failure of the purchaser to pay the full purchase price
or fulfill its contractual obligations, (ii) the purchaser becomes obligated to
pay OA&M costs and (iii) the segment of the system related to the capacity
purchased is ready for service.
 
  CPAs for capacity that do not meet the Company's revenue recognition policy
are not recorded in the Company's consolidated financial statements.
 
  Since the RFS date for the United States--United Kingdom segment of AC-1,
which occurred on May 26, 1998, the Company's revenues have been comprised
principally of revenues from sales of cable capacity on AC-1 and the sale of
associated terrestrial capacity.
 
  Pursuant to the CPAs, the Company bills its customers for operations, direct
administration and maintenance costs incurred, plus 10%, subject to certain
annual maximum amounts.
 
COST OF CAPACITY SOLD; CONSTRUCTION IN PROGRESS; CAPACITY AVAILABLE FOR SALE
 
  Construction costs incurred with respect to each segment of an undersea cable
system are reflected as "Construction in Progress" in the Company's
consolidated balance sheet until a segment becomes operational, at which time
such costs are reflected as Capacity Available For Sale. Capacity Available For
Sale is recorded at the lower of cost or fair value less cost to sell and is
charged to Cost of Capacity Sold in the period the related revenues are
recognized. Fair value of capacity is derived from a third party consultant's
market study of expected sales of capacity.
 
  The Company capitalizes the cost of acquiring terrestrial capacity and
records in Capacity Available for Sale amounts equal to the present value of
future payments associated with the acquisition of such terrestrial capacity
(excluding from such payments amounts attributable to operations and
maintenance costs).
 
  Construction in Progress includes direct expenditures for construction of
systems, including advisory, consulting and legal fees, interest during
construction and amortized debt issuance costs incurred during the construction
phase.
 
  Amounts charged to Cost of Capacity Sold are calculated based on the ratio of
capacity revenues recognized in a period to total expected capacity revenues
over the life of the system, multiplied by the total cost to construct the
system. Management's forecast of revenues expected over the life of the system
will be supported by an independent consultant's forecast. Changes in
management's estimate of the expected revenues to be derived from sales of a
cable system's capacity will result in adjustments to the calculations of Cost
of Capacity Sold. These adjustments will be recorded on a prospective basis
over future periods commencing with the period when management revises its
estimate. The cost of acquiring terrestrial capacity is charged to Cost of
Capacity Sold in the period during which the related revenues are recognized.
 
OPERATING EXPENSES
 
  In addition to Cost of Capacity Sold, the Company's operating expenses
principally comprise sales and marketing, operations and maintenance, general
and administrative and network development costs. Costs relating to the
Company's evaluation of possible additional systems are expensed as incurred.
 
RESULTS OF OPERATIONS FOR THE PERIOD FROM MARCH 19, 1997 (DATE OF INCEPTION) TO

  Interest Income. Pursuant to the purchase agreement relating to the sale of
its outstanding $150 million GTH Senior Notes, the Company was required to
maintain certain amounts in restricted cash and cash equivalents accounts to
fund future semi-annual interest payments on such notes. Interest income earned
on this balance, together with interest income earned on cash raised from
financing and cash on CPA deposits, totalled
 
                                       33
<PAGE>
 
approximately $2.9 million for the period from March 19, 1997 to December 31,
1997. The Company utilized a portion of the net proceeds from the Note Offering
to repurchase the GTH Senior Notes. See "--Liquidity and Capital Resources."
 
  Expenses. During the period ended December 31, 1997, the Company incurred
expenses of $3.1 million. Of this amount, approximately $1.4 million was
attributable to sales and marketing expenses, relating principally to AC-1,
$0.1 related to network development and approximately $1.6 million was
attributable to general and administrative expenses.
 
  GTH Preference Share Dividends. The GTH Preference Shares accrued compounding
dividends at an annual rate of 14%. During the period ended December 31, 1997,
the Company recorded preference share dividends of approximately $12.7 million.
This amount is comprised of $11.1 million in paid-in-kind ("PIK") dividends,
$1.0 million in amortization of the discount on issuance and $0.6 million in
amortization of issuance costs. The $11.1 million in PIK dividends includes
$1.3 million accrued but unpaid as of December 31, 1997.
 
  In connection with the issuance of the GTH Preference Shares, the exclusive
placement agent thereof, CIBC Wood Gundy Securities Corp., received a total of
19,852,950 shares of Class A common stock of Global Crossing Ltd., LDC ("Old
GCL") for no additional consideration. The Company has recorded the $13,235,000
estimated fair value of such shares as a discount in the carrying value of the
GTH Preference Shares, which discount is being amortized over the term of such
shares. See "Certain Transactions--Transactions Regarding Class A Shares of Old
GCL."
 
  The Company utilized a portion of the net proceeds from the Note Offering to
redeem the GTH Preference Shares effective June 17, 1998. See "--Liquidity and
Capital Resources."
 
  Net Loss and Net Loss Applicable to Common Shareholder. During the period
ended December 31, 1997, the Company had a net loss applicable to common
shareholder of $12.9 million, resulting primarily from the $12.7 million of
dividends on the GTH Preference Shares described above.
 
RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1998 AND
SEPTEMBER 30, 1997
 
 Revenues
 
  During the three months ended September 30, 1998, the Company executed CPAs
and ICPAs totaling approximately $211.3 million, bringing the total since
inception to $767.3 million. Of this amount, the Company recognized revenues of
$115.9 million on sales of capacity relating to AC-1 for the three months ended
September 30, 1998, in addition to revenues from operation and maintenance
services of $1.8 million. Of the $767.3 million executed CPAs and ICPAs, $550.6
million has not yet been reflected in the financial statements because the
segment has not reached RFS or the purchaser has not obtained the right to use
the capacity. During the three months ended September 30, 1998, the Company
entered into CPAs and ICPAs with two additional international
telecommunications carriers and sold approximately 10% of the minimum projected
sales capacity of 512 circuits on the AC-1 system.
 
 Expenses
 
  Cost of capacity sold.  For the three months ended September 30, 1998, the
Company recognized $49.2 million in cost of capacity sold, resulting in a gross
margin on capacity sales of 58%. The Company calculates cost of capacity sold
for AC-1 based on the ratio of the period's actual revenue to total expected
revenues given a minimum projected sales capacity of 512 circuits times the
construction cost of the system. This calculation of cost of sales matches
costs with the relative value of each sale. Cost of capacity sold also includes
the cost of terrestrial capacity sold of approximately $7.7 million during the
three months ended September 30, 1998. There were no sales or related costs
recognized in the three months ended September 30, 1997, as the Company was in
its development stage.

OA&M costs on AC-1 of $8.2 million during the three months ended September 30,
1998. The Company has entered into an agreement with TSSL relating to
operations, administration and maintenance of AC-1 which limits the Company's
total OA&M expense for the system. Following the AC-1 full system RFS date, the
Company anticipates that its OA&M costs will be largely recovered through
charges to its customers under the terms of CPAs. There were no OA&M costs in
the three months ended September 30, 1997, as the Company was in its
development stage.
 
  Sales and marketing. During the three months ended September 30, 1998, the

commissions of $3.4 million incurred on the capacity sales recognized during
this period. During the three months ended September 30, 1997, the Company
incurred sales and marketing costs of approximately $0.1 million. The increase
from 1997 was due to additions in headcount, occupancy costs, plus marketing,
commissions paid and other promotional expenses to support the Company's rapid
growth.
 
  Network development. The Company incurred network development costs during
the three months ended September 30, 1998 of $2.9 million relating to the

approximately $0.6 million.
 
  Stock related compensation expense. The Company recognized approximately $1.7
million of compensation expense during the three months ended September 30,
1998 relating to options issued under GCL's Stock Incentive Plan. GCL's Stock
Incentive Plan commenced on January 21, 1998 and therefore no issuances were
made during the three months ended September 30, 1997.
 
  Equity in loss of Pacific Crossing Ltd. During April 1998, the Company
entered into a joint venture to construct an undersea cable system, PC-1. PC-1
is owned and operated by PCL. The Company has an economic interest in PCL
represented by a 50% direct voting interest and, through one of the joint
venture partners, owns a further 8% economic non-voting interest. The $1.0
million loss represents the Company's 58% equity in the loss of this joint
venture for the three months ended September 30, 1998.
 
  Interest Income and Interest Expense
 
  Interest income. The Company earned interest income of $8.3 million and $1.2
million in the three months ended September 30, 1998 and 1997, respectively.

inception to $767.3 million. Of this amount, the Company recognized revenues of
$216.7 million on sales of capacity relating to AC-1 for the nine months ended
September 30, 1998, in addition to revenues from operations and maintenance
services of $2.2 million. The remaining $550.6 million has not yet been
reflected in the financial statements because the segment has not reached RFS,
or the purchaser has not obtained the right to use the capacity. During the
nine months ended September 30, 1998, the Company entered into CPAs and ICPAs
with 24 international telecommunications carriers and sold approximately 30% of
the minimum projected sales capacity of 512 circuits on the AC-1 system.
 
 Expenses
 
  Cost of capacity sold. For the nine months ended September 30, 1998, the
Company recognized $90.4 million in cost of capacity sold, resulting in a gross
margin on capacity sales of 58%. The Company calculates cost of capacity sold
for AC-1 based on the ratio of the period's actual revenue to total expected
revenues, assuming minimum projected sales capacity of 512 circuits, times the
construction cost of the system. This calculation of cost of sales matches
costs with the relative value of each sale. Cost of capacity sold also includes
the cost of terrestrial capacity sold of approximately $16.6 million during the
nine months ended September 30, 1998. There were no sales or related costs
recognized in the nine months ended September 30, 1997, as the Company was in
its development stage.
 
  Operations, administration and maintenance ("OA&M"). The Company incurred
OA&M costs of $10.7 million during the nine months ended September 30, 1998.
The Company entered into an agreement with TSSL relating to operations,
administration and maintenance of AC-1, which limits the Company's total OA&M
expense for the system. Following the AC-1 full system RFS date, the Company
anticipates that its OA&M costs will be largely recovered through charges to
its customers under the terms of CPAs. There were no OA&M costs during the

<PAGE>
 
recognized during this period. During the period from March 19, 1997 (Date of
Inception) to September 30, 1997, the Company incurred sales and marketing
costs of approximately $0.1 million. The increase from 1997 was due to
additions in headcount and occupancy costs, plus marketing, commissions paid
and other promotional expenses to support the Company's rapid growth.
 
  Network development. The Company incurred network development costs during
the nine months ended September 30, 1998 of $7.2 million relating to the

and administrative costs of $0.7 million.
 
  Termination of Advisory Services Agreement with PCG Telecom Services LLC. In
connection with the development and construction of AC-1, GCL entered into an
Advisory Services Agreement with PCG Telecom Services LLC, an affiliate of the
Company, providing for the payment by the Company of an advisory fee of 2.0% of
the gross revenues of ACL. GCL's Board of Directors also approved similar
advisory fees and authorized GCL to enter into similar agreements with respect
to other cable systems being developed by the Company. GCL has acquired the
rights of the persons entitled to the fees payable under these agreements in
consideration for the issuance of GCL Common Stock which had at the time of
issuance an aggregate value of $135.0 million, and the cancellation of
approximately $2.7 million owed to GCL under a related advance agreement. This
charge of $137.7 million relating to the termination of the Advisory Services
Agreement was contributed to the Company and is reflected in the statement of
operations for the nine month period ended September 30, 1998. In addition, the
Company recognized approximately $2.0 million of advisory fees incurred prior
to termination of the contract.
 
  Stock related compensation expense. The Company recognized approximately $8.2
million of stock related compensation expense during the nine months ended
September 30, 1998 relating to options issued under GCL's Stock Incentive Plan.

issuances were made during the period from March 19, 1997 (Date of Inception)
to September 30, 1997. During the nine months ended September 30, 1998, the
Company also recorded stock-related expense of $2.3 million relating to shares
issued during this period.
 
  Equity in loss of Pacific Crossing Ltd. During April 1998, the Company
entered into a joint venture to construct a cable system project, PC-1. PC-1 is
owned and operated by PCL. The Company has an economic interest in PCL
represented by a 50% direct voting interest and, through one of the joint
venture partners, owns a further 8% economic non-voting interest. The $1.0
million loss represents the Company's 58% equity in the loss of this joint
venture for the nine months ended September 30, 1998.

  Interest income. The Company reported interest income of $12.9 million in the
nine months ended September 30, 1998 and $2.5 million during the period from
March 19, 1997 (Date of Inception) to September 30, 1997. Such interest income
represents earnings on cash raised from financings, the GCL Stock Offerings of
GCL which was contributed to the Company and on CPA deposits.
 
  Interest expense. During the nine months ended September 30, 1998, the
Company incurred $62.6 million in interest costs, including the amortization of

                                       37
<PAGE>
 
 Provision for income taxes
 
  The income tax provision of $16.3 million for the nine months ended September
30, 1998, provides for taxes on profits earned from capacity sales and OA&M
revenues where subsidiaries of the Company have a presence in taxable
jurisdictions. During the period from March 19, 1997 (Date of Inception) to
September 30, 1997, the Company has incurred operating losses, which relate to
non-taxable jurisdictions and therefore, such losses incurred to date cannot be
applied against future taxable earnings. Accordingly, no tax provision or
deferred tax benefit was recorded in 1997.
 
 Extraordinary item
 
  On May 18, 1998, the Company recognized an extraordinary loss of $19.7
million on the repurchase of the Global Telesystems Holding Ltd.'s senior notes
("GTH Senior Notes"), comprised of a premium of $9.8 million and a write-off of
$9.9 million of unamortized deferred financing costs.
 
 Preference share dividends
 
  The former GTH Preference Shares accrued compounding dividends at an annual
rate of 14%. During the nine months ended September 30, 1998, the Company
recorded preference share dividends of approximately $8.3 million. Preference
share dividends for the period from March 19, 1997 (Date of Inception) to
September 30, 1997 were $8.4 million.
 
 Redemption of preference shares
 
  The redemption of the GTH Preference Shares occurred on June 17, 1998 and
resulted in a $34.1 million charge against equity. This amount was comprised of
a $15.9 million redemption premium and a write-off of $18.2 million of
unamortized discount and issuance costs. The redemption premium and write-off
of unamortized discount and issuance costs are treated as a deduction to arrive
at net loss applicable to common shareholders in the consolidated statement of
operations.
 
 Net income (loss) and Net income (loss) applicable to common shareholder
 
  The Company incurred a net loss of $113.7 million for the nine months ended
September 30, 1998, compared to net income of $1.7 million in the period from
March 19, 1997 (Date of Inception) to September 30, 1997. The net loss for the
nine months ended September 30, 1998 reflects an extraordinary loss on
retirement of the GTH Senior Notes of $19.7 million and a non-recurring charge
of $139.7 million relating to the termination of its Advisory Services
Agreement. The Company's net income before these items would have been $45.7
million.
 
  During the nine months ended September 30, 1998, the Company reported a net
loss applicable to common shareholder of $156.2 million. This loss reflects GTH
Preference Share dividends of $8.3 million and the redemption of GTH Preference
Shares of $34.1 million. During the period from March 19, 1997 (Date of
Inception) to September 30, 1997, the Company incurred a net loss applicable to
common shareholder of $6.7 million after GTH Preference Share dividends of $8.4
million.
 
 BALANCE SHEET AS OF SEPTEMBER 30, 1998
 
  Cash and cash equivalents. At September 30, 1998, cash and cash equivalents
of $485.7 million include proceeds of GCL's Stock Offerings of $392.1 million,
which was contributed to the Company.
 
  Restricted cash and cash equivalents.  At September 30, 1998, restricted cash
and cash equivalents includes: $231.0 million for the collateralization of the
credit facility used to make initial payments on the PC-1 construction, $74.8
million reserved for funding future interest payable on the Senior Notes, and
$86.0 million received pursuant to CPAs and ICPAs on AC-1 only in accordance
with the terms of the AC-1 credit facility.
 
                                       38
<PAGE>
 
These funds may be used only for purchases of terrestrial capacity relating to
AC-1, interest and principal payments on the AC-1 credit facility and to fund
reserves for future upgrades to AC-1.
 
  Capacity available for sale, Construction in progress and Investment in
PCL. The Company's investment in capacity available for sale, construction in
progress, and investment in PCL totaled approximately $1,033 million as of
September 30, 1998. Upon the GCL Stock Offerings each PCG Warrant then
outstanding was converted into a fraction of a share of GCL Common Stock based
upon the ratio of the per share valuation at the time of conversion less the
per share exercise price of the warrants, divided by the per share valuation at
the time of conversion, together with a new warrant ("New PCG Warrants") to
purchase the remaining fraction of shares at an exercise price equal to $19.00
(the Price to Public per share of the GCL Stock Offerings). These amounts were
contributed to the Company and increased additional paid-in-capital by $275.3
million. This amount was allocated on a pro rata basis to PCL, PAC and MAC
according to the estimated cost of each system. Accordingly, the Company
recorded $163.1 million as an investment in PCL and $64.6 million and $47.6
million as Construction in Progress for PAC and MAC, respectively.
 
  Long term debt and Senior Notes. The long term debt of $337.8 million as of
September 30, 1998 represents the long term portion of the Company's
outstanding balance on the AC-1 Credit Facility. The Senior Notes balance of
$796.4 million represents the net proceeds from the Company's issuance of the
Senior Notes, adjusted for amortization of the original issue discount.
 
  During the nine months ended September 30, 1998, the Company paid fees of
$7.0 million to PCG, a shareholder of GCL, relating to system evaluation costs
incurred by PCG. This amount was treated as a dividend and charged against
additional paid-in-capital.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's principal capital expenditure requirements involve the
construction of undersea and terrestrial cable systems. As of September 30,
1998 and September 30, 1997, the Company had incurred approximately $764.2
million and $298.5 million, respectively, of capital expenditures in respect of
AC-1, principally for system construction costs and purchases of terrestrial
capacity. The Company was also committed to a further $44.1 million and $364.5
million, respectively, of capital expenditures under the AC-1 Contract in
connection with the completion of AC-1. Terrestrial capacity purchases are
recorded at the present value of future payments (excluded from such payments
are amounts attributable to OA&M required to be made by the Company for such
capacity).
 
  The total cost of AC-1 is estimated at approximately $750 million, excluding
purchases of terrestrial capacity and potential future upgrades but including
financing costs capitalized during the period AC-1 is under construction. As of
September 30, 1998 and September 30, 1997, the Company had borrowings
outstanding of $365.1 million and $5.0 million, respectively, under the AC-1
Credit Facility.
 
  On May 18, 1998, the Company obtained $796.2 million in proceeds from the
issuance of its Senior Notes. The Company utilized the net proceeds from these
notes (i) to purchase all of the $150 million outstanding GTH Senior Notes,
(ii) to redeem all of the $100 million outstanding GTH Preference Shares, (iii)
to repay in full the $67.2 million outstanding under a bridge credit facility,
(iv) to make approximately $315 million of equity investments in certain of the
Company's systems and (v) for general corporate purposes, including $74 million
to fund a one-year interest reserve on the Senior Notes.
 
  During August 1998, GCL completed its GCL Stock Offerings and received net
proceeds of $392.1 million. This amount was contributed to the Company and the
Company intends to use the proceeds for (i) construction of the Global Crossing
Network, (ii) investment in telecommunications companies and Internet service
providers, (iii) investment in GAL and (iv) general corporate purposes. As of
September 30, 1998, these proceeds were invested in short-term, interest-
bearing U.S. Government securities and certain other short term, investment
grade securities.

  Cash provided by operating activities was approximately $82.6 million for the
nine months ended September 30, 1998, and $2.7 million for the period from
March 19, 1997 (Date of Inception) to September 30, 1997, and principally
represents cash received from deposits and payments for activated capacity
pursuant to signed CPAs, plus interest income received, less sales and
marketing, network development, and general and administrative expenses paid.
 
  Cash provided by financing activities was approximately $689.1 million for
the nine months ended September 30, 1998, and primarily represents borrowings
under the AC-1 Credit Facility, proceeds from the issuance of the Senior Notes
and proceeds from the GCL Stock Offerings, less the redemption of the GTH
Preference Shares and the retirement of the GTH Senior Notes and less the
increase in proceeds on borrowings held in restricted cash and cash
equivalents. Cash provided by financing activities of $296.8 million for the
period from March 19, 1997 (Date of Inception) to September 30, 1997, relates
to net proceeds from the issuance of common stock, GTH Preference Shares and
GTH Senior Notes, and borrowings under the AC-1 Credit Facility, less finance
and organization costs paid, and less costs related to the issuance of common
and preferred stock.
 
  Cash used in investing activities was approximately $287.4 million and $262.5
million for the nine months ended September 30, 1998, and the period from March
19, 1997 (Date of Inception) to September 30, 1997, respectively, and
represents cash paid for Construction in Progress and Capacity Available for
Sale.
 
  The Company is currently actively developing four additional systems, PC-1,
MAC, PAC and PEC. The Company estimates that the costs of constructing these
systems will total approximately $2,725 million, including financing costs but
excluding potential future upgrades and amounts capitalized with respect to the
PCG Warrants. The Company expects to use approximately $315 million of the net
proceeds from the Senior Notes to fund initial investments in PC-1, MAC and
PAC.
 
  Effective July 21, 1998, the Company signed a commitment letter for $300
million non-recourse project debt financing of PAC. Effective July 30, 1998,
the Company entered into a credit agreement for the $850 million non-recourse
project debt financing of PC-1 (including $50 million for the initial upgrade
of the PC-1 system). Effective November 25, 1998, the Company entered into a
credit agreement for the $260 million non-recourse project debt financing of
MAC (including $30 million for the initial upgrade of the MAC system).
 
  Because the Company's cost of developing and constructing its systems, as
well as operating its business, will depend on a variety of factors (including
the Company's ability to successfully negotiate construction supply contracts
at favorable prices, the ability of the Company to generate sufficient sales to
customers, changes in the competitive environment of the markets served by the
Company, the estimated levels of participation by the Company's joint venture
partners and changes in technology), actual costs and revenues may vary from
expected amounts, possibly materially, and such variations will likely impact
the Company's future capital requirements. The development of additional
systems, which may be pursued by the Company, would lead to additional future
capital requirements.
 
  The Company has raised or expects to raise the additional capital required to
finance these cable systems through a combination of commercial bank
borrowings, non-recourse project financings, public and private offerings of
debt and equity securities, vendor financing and sales of dark fiber on PEC. In
this regard, subsequent to the period ending September 30, 1998, the Company
has signed an agreement with Cable & Wireless PLC for the sale of dark fiber on
the PEC network for a purchase price of approximately $100 million. There can
be no assurance that the Company will be successful in raising additional
capital at all or on terms acceptable to the Company. See "Risk Factors--
Substantial Future Capital Requirements" and "Risk Factors--Risks Related to
Completing our Cable Systems."
 
  During April 1998, a supply contract (the "PC-1 Contract") was entered into
with TSSL to construct PC-1. The estimated total cost of PC-1 is $1,200
million, including financing costs which will be capitalized during the period
PC-1 is under construction. Of this amount, the Company will be required to
contribute
 
                                       40
<PAGE>
 
equity in the amount of approximately $231 million. This amount has been placed
in escrow pursuant to the terms of the PC-1 credit facility and is included in
amounts shown as restricted cash. The balance of the $1,200 million will be
funded by the joint venture partners and the PC-1 credit facility. During June
1998, the Company entered into a supply contract (the "MAC Contract") with
Alcatel requiring construction payments of approximately $221 million to
construct MAC. In July 1998, the Company entered into a supply contract (the
"PAC Contract") requiring construction payments of approximately $313 million
with TSSL to construct PAC.
 
  The Company has extended financing to a small number of customers in
connection with certain CPAs. The financing terms provide for installment
payments over a period of up to four years. The Company believes that its
extension of financing to its customers will not have a material effect on the
Company's liquidity.
 
  The Company has entered into commission sharing agreements providing for the
payment to third parties of commissions with respect of marketing of capacity
on the AC-1 and PC-1 systems. Payments by the Company of these commissions is
fully contingent upon the receipt by the Company of cash payment under the
related CPAs and, accordingly, payment by the Company of these commissions has
no material effect on its liquidity.
 
FOREIGN CURRENCY EXPOSURE
 
  Most of the Company's sales and most of its expenditures are denominated in
U.S. dollars. Monetary assets and liabilities denominated in foreign currencies
at year end are translated into U.S. dollars at the rate of exchange at that
date. Resulting gains or losses on exchange are recorded in the statement of
operations.
 
INFLATION
 
  Management does not believe that its business is impacted by inflation to a
significantly different extent than the general economy.
 
YEAR 2000 COMPLIANCE
 
  Global Crossing believes that its computer information systems are or will be
Year 2000 ("Y2K") compliant. The Company has received assurances regarding AC-
1, the Company's only active system at this time, from TSSL and Lucent
Technologies stating Y2K compliance status of their respective systems. The
Company does not currently have such information regarding other suppliers of
the Company's networks under development.
 
  The Company is also subject to external forces that generally affect industry
and commerce, such as utility, transportation or other infrastructure failures
and interruptions. In addition to reviewing its own systems, the Company is
submitting requests to third party service providers to obtain information as
to their compliance efforts. In the event that any of the Company's significant
third parties do not successfully and timely achieve Y2K compliance, the
Company's business or operations could be adversely affected. The Company is
developing contingency plans to address any potential Y2K compliance failure.
 
  Management does not believe that the costs of addressing Y2K issues will have
a material adverse impact on the Company's financial condition or results of
operations. The costs of Y2K compliance and the dates on which the Company
believes it will complete Y2K remediation and modifications are based on
management's best estimates of future events, including the continued
availability of certain resources, third-party modifications, plans, and other
factors. Actual results could differ from those anticipated.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
  The Issuer issued and sold the Old Preferred Stock to the initial purchasers
on November 24, 1998 pursuant to a purchase agreement. The initial purchasers
subsequently resold the Old Preferred Stock in reliance on Rule 144A and other
exemptions from registration under the Securities Act of 1933. The initial
purchasers required as a condition to the purchase of the shares of Old
Preferred Stock that the Issuer grant the purchasers of the shares of Old
Preferred Stock certain registration rights pursuant to a registration rights
agreement (the "Registration Rights Agreement"). The Registration Rights
Agreement required the Issuer to file with the Securities and Exchange
Commission following the closing of the offering of the shares of Old Preferred
Stock on December 2, 1998 (the "Closing Date"), a registration statement
relating to an exchange offer pursuant to which shares which are substantially
identical to the shares of Old Preferred Stock would be offered in exchange for
the then outstanding shares of Old Preferred Stock tendered at the option of
the holders thereof. The form and terms of the shares of Exchange Preferred
Stock will be identical in all material respects to the form and terms of the
shares of Old Preferred Stock except:
 
  . that the shares of Exchange Preferred Stock will have been registered
    under the Securities Act,
 
  . that the shares of Exchange Preferred Stock will not be entitled to
    certain registration rights which are applicable to the shares of Old
    Preferred Stock under the Registration Rights Agreement, and
 
  . certain contingent dividend rate provisions applicable to the shares of
    Old Preferred Stock are generally not applicable to the shares of
    Exchange Preferred Stock.
 
  New Exchange Notes issuable in exchange for shares of Exchange Preferred
Stock will have the same terms as Exchange Notes issuable in exchange for
shares of Old Preferred Stock. In the event that the applicable interpretations
of the staff of the Securities and Exchange Commission do not permit the Issuer
to effect the Exchange Offer, the Issuer agreed to use its reasonable best
efforts to cause to become effective a shelf registration statement with
respect to the resale of the shares of Old Preferred Stock and to keep such
resale registration statement effective for a period of at least two years. The
Issuer is making the Exchange Offer to satisfy its contractual obligations
under the Registration Rights Agreement.
 
  The holders of any shares of Old Preferred Stock not tendered in the Exchange
Offer will not be entitled to require the Issuer to file a resale registration
statement, and the dividend rate on such shares of Old Preferred Stock will
remain at 10 1/2%. For more information, see "Description of the Exchange
Notes--Exchange Offer; Registration Rights."
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this prospectus and
in the accompanying Letter of Transmittal (which together constitute the
Exchange Offer), the Issuer will accept for exchange Old Preferred Stock which
are properly tendered on or prior to the Expiration Date and not withdrawn as
permitted below. The shares of Exchange Preferred Stock issued pursuant to the
Exchange Offer will be delivered promptly following the Expiration Date. The
Issuer will issue $100 liquidation preference of Exchange Preferred Stock in
exchange for each $100 liquidation preference of outstanding Old Preferred
Stock accepted in the Exchange Offer.
 
  Based on an interpretation by the staff of the Securities and Exchange
Commission set forth in SEC no-action letters issued to unrelated third
parties, the Issuer believes that shares of Exchange Preferred Stock issued
pursuant to the Exchange Offer in exchange for shares of Old Preferred Stock
may be offered for resale, resold and otherwise transferred by the holders
thereof (other than a Restricted Holder) without compliance with the
registration and prospectus delivery provisions of the Securities Act of 1933,
provided that such shares of Exchange Preferred Stock are acquired in the
ordinary course of such holders' business and such holders are
 
                                       42
<PAGE>
 
not participating, do not intend to participate and have no arrangement or
understanding with any person to participate in the distribution of such shares
of Exchange Preferred Stock. See "K-III Communications Corporation," SEC No-
Action Letter (available May 14, 1993); "Mary Kay Cosmetics, Inc.," SEC No-
Action Letter (available June 5, 1991); "Morgan Stanley & Co., Incorporated,"
SEC No-Action Letter (available June 5, 1991); and "Exxon Capital Holdings
Corporation," SEC No-Action Letter (available May 13, 1988). Each broker-dealer
that receives shares of Exchange Preferred Stock for its own account in
exchange for shares of Old Preferred Stock, where such shares of Old Preferred
Stock were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such shares of Exchange Preferred
Stock. For more information, see "Plan of Distribution."
 
  If any person were to participate in the Exchange Offer for the purpose of
distributing securities in a manner not permitted by the Security and Exchange
Commission's interpretation, such person:
 
  . could not rely on the position of the staff of the Security and Exchange
    Commission enunciated in "Exxon Capital Holdings Corporation" or similar
    interpretive letters, and
 
  . must comply with the registration and prospectus delivery requirements of
    the Securities Act of 1933 in connection with a secondary resale
    transaction.
 
Accordingly, each eligible holder wishing to accept the Exchange Offer must
represent to the Issuer in the letter of transmittal that the conditions
described above have been met.
 
  In connection with the issuance of the shares of Old Preferred Stock, the
Issuer arranged for the inclusion of the Old Preferred Stock initially
purchased by qualified institutional buyers on the Private Offerings, Resales
and Trading through Automated Linkages (PORTAL) Market of the National
Association of Securities Dealers, Inc. The Issuer also arranged for the shares
of Old Preferred Stock initially purchased by qualified institutional buyers to
be issued and transferable in book-entry form through the facilities of the
Depository, acting as depository, and in the DTC's Same-Day Funds Settlement
System. The shares of Exchange Preferred Stock will also be issuable and
transferable in book-entry form through the Depository in the Same-Day Funds
Settlement System.
 
  As of the date of this prospectus, $500,000,000 in aggregate liquidation
preference of the Old Preferred Stock is outstanding.
 
  This prospectus, together with the Letter of Transmittal, is being sent to
all registered holders of shares of Old Preferred Stock as of      , 1998 (the
"Record Date").
 
  The Issuer shall be deemed to have accepted validly tendered shares of Old
Preferred Stock when, as and if the Issuer has given oral or written notice
thereof to the Exchange Agent. The Exchange Agent will act as agent for the
tendering holders of shares of Old Preferred Stock for the purpose of receiving
shares of Exchange Preferred Stock from the Issuer and delivering shares of
Exchange Preferred Stock to such holders.
 
  If any tendered shares of Old Preferred Stock are not accepted for exchange
because of an invalid tender or the occurrence of certain other events set
forth herein, certificates for any such unaccepted shares of Old Preferred
Stock will be returned, without expense, to the tendering holder thereof as
promptly as practicable after the Expiration Date.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" means 5:00 p.m., New York City time, on   , 1999;
provided, however, that if the Issuer, in its sole discretion, has extended the
period of time for which the Exchange Offer is open, the term "Expiration Date"
means the latest time and date to which the Exchange Offer is extended.
 
                                       43
<PAGE>
 
  The Issuer expressly reserves the right:
 
  . to delay acceptance of any shares of Old Preferred Stock, to extend the
    Exchange Offer or to terminate the Exchange Offer and to refuse to accept
    shares of Old Preferred Stock not previously accepted, if any of the
    conditions set forth herein under "--Conditions" shall have occurred and
    shall not have been waived by the Issuer, by giving oral or written
    notice of such delay, extension or termination to the Exchange Agent, and
 
  . to amend the terms of the Exchange Offer in any manner deemed by the
    Issuer to be advantageous to the holders of the shares of Old Preferred
    Stock.
 
The Issuer will notify any holder as promptly as practicable either orally or
by written notice of any such delay in acceptance, extension, termination or
amendment. If the Exchange Offer is amended in a manner determined by the
Issuer to constitute a material change, the Issuer will promptly disclose such
amendment in a manner reasonably calculated to inform the holders of shares of
Old Preferred stock of such amendment.
 
  Without limiting the manner in which the Issuer may choose to make public
announcements of any delay in acceptance, extension, termination or amendment
of the Exchange Offer, the Issuer shall have no obligation to publish,
advertise, or otherwise communicate any such public announcement, other than by
making a timely release to a financial news service.
 
ACCRUAL OF DIVIDENDS ON THE EXCHANGE PREFERRED STOCK
 
  The Exchange Preferred Stock will accrue dividends from December 2, 1998,
payable semi-annually in arrears on June 1 and December 1 of each year
commencing on June 1, 1999, at the rate per annum equal to 10 1/2% of the
liquidation preference per share of the Exchange Preferred Stock. Holders of
shares of Old Preferred Stock whose shares of Old Preferred Stock are accepted
for exchange will be deemed to have waived the right to receive any payment in
respect of dividends on such shares of Old Preferred Stock accrued from
December 2, 1998 until the date of the issuance of the Exchange Preferred
Stock.
 
PROCEDURES FOR TENDERING SHARES OF OLD PREFERRED STOCK
 
  To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof and mail or otherwise deliver
such Letter of Transmittal or such facsimile, together with the shares of Old
Preferred Stock (unless such tender is being effected pursuant to the procedure
for book-entry transfer described below) and any other required documents, to
the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration
Date. Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be 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 another eligible institution (an "Eligible Institution")
unless the share of Old Preferred Stock tendered pursuant thereto are tendered
by:
 
  . 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 an Eligible Institution.
 
  Any financial institution that is a participant in DTC's Book-Entry Transfer
Facility system may make book-entry delivery of the shares of Old Preferred
Stock by causing the DTC to transfer such shares of Old Preferred Stock into
the Exchange Agent's account in accordance with the DTC's procedure for such
transfer. Although delivery of shares of Old Preferred Stock may be effected
through book-entry transfer into the Exchange Agent's account at the DTC, the
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received or
 
                                       44
<PAGE>
 
confirmed by the Exchange Agent at its addresses set forth herein prior to 5:00
p.m., New York City time, on the Expiration Date. DELIVERY OF DOCUMENTS TO DTC
IN ACCORDANCE WITH ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE
AGENT.
 
  The tender by a holder of shares of Old Preferred Stock will constitute an
agreement between such holder and the Issuer in accordance with the terms and
subject to the conditions set forth herein and in the Letter of Transmittal.
 
  Holders must deliver all documents to the Exchange Agent at its address set
forth herein. Holders may also request that their respective brokers, dealers,
commercial banks, trust companies or nominees effect such tender for such
holders.
 
  Holders may choose any method of delivery of the shares of Old Preferred
Stock and the Letter of Transmittal and all other required documents to the
Exchange Agent. It is recommended that holders use an overnight or hand
delivery service, instead of delivery by mail. In all cases, sufficient time
should be allowed to assure timely delivery. No Letter of Transmittal or shares
of Old Preferred Stock should be sent to the Issuer.
 
  Only a holder of shares of Old Preferred Stock may tender such shares of Old
Preferred Stock in the Exchange Offer. The term "holder" with respect to the
Exchange Offer means any person in whose name shares of Old Preferred Stock are
registered on the books of the Issuer or any other person who has obtained a
properly completed bond power from the registered holder or any person whose
shares of Old Preferred Stock are held of record by DTC who desires to deliver
such shares of Old Preferred Stock at DTC.
 
  Any beneficial holder whose shares of Old Preferred Stock are registered in
the name of his broker, dealer, commercial bank, trust company or other nominee
and who wishes to tender his shares of Old Preferred Stock should contact the
registered holder promptly and instruct such registered holder to tender on
his/her behalf. If such beneficial holder wishes to tender on his/her own
behalf, such beneficial holder must, prior to completing and executing the
Letter of Transmittal and delivering his/her shares of Old Preferred Stock,
either make appropriate arrangements to register ownership of the shares of Old
Preferred Stock in such holder's name or obtain a properly completed bond power
from the registered holder. The transfer of record ownership may take
considerable time.
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any shares of Old Preferred Stock listed therein, such shares of Old
Preferred Stock must be endorsed or accompanied by appropriate bond powers
which authorize such person to tender the shares of Old Preferred Stock on
behalf of the registered holder, in either case signed as the name of the
registered holder or holders appears on the shares of Old Preferred Stock.
 
  If the Letter of Transmittal or any shares of Old Preferred Stock or bond
powers are signed by trustees, executors, administrators, guardians, attorneys-
in-fact, officers of a corporation or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing. In
addition, unless waived by the Issuer, evidence satisfactory to the Issuer of
their authority to so act must be submitted with the Letter of Transmittal.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered shares of Old Preferred
Stock will be determined by the Issuer in its sole discretion, which
determination will be final and binding. The Issuer reserves the absolute right
to reject any and all shares of Old Preferred Stock not validly tendered or any
shares of Old Preferred Stock the Issuer's acceptance of which would, in the
opinion of counsel for the Issuer, be unlawful. The Issuer also reserves the
absolute right to waive any irregularities or conditions of tender as to
particular shares of Old Preferred Stock. The Issuer's 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,
any defects or irregularities in connection with tenders of shares of Old
Preferred Stock must be cured within such time as the Issuer shall determine.
Neither the Issuer, the Exchange Agent nor any other person shall be under any
duty to give notification of
 
                                       45
<PAGE>
 
defects or irregularities with respect to tenders of shares of Old Preferred
Stock nor shall any of them incur any liability for failure to give such
notification. Tenders of shares of Old Preferred Stock will not be deemed to
have been made until such irregularities have been cured or waived. Any shares
of Old Preferred Stock received by the Exchange Agent that are not validly
tendered and as to which the defects or irregularities have not been cured or
waived will be returned by the Exchange Agent without cost to the tendering
holder of such shares of Old Preferred Stock unless otherwise provided in the
Letter of Transmittal, as soon as practicable following the Expiration Date.
 
  By tendering, each holder will represent to the Issuer that, among other
things:
 
  . the shares of Exchange Preferred Stock acquired pursuant to the Exchange
    Offer are being obtained in the ordinary course of such holder's
    business,
 
  . such holder is not participating, does not intend to participate and has
    no arrangement or understanding with any person to participate, in a
    distribution of such shares of Exchange Preferred Stock,
 
  . such holder is not an "affiliate," as defined under Rule 405 of the
    Securities Act of 1933, of the Issuer, and
 
  . such holder is not a broker-dealer who acquired shares of Old Preferred
    Stock directly from the Issuer to resell pursuant to Rule 144A or any
    other available exemption under the Securities Act of 1933.
 
TENDER OF OLD PREFERRED STOCK HELD THROUGH DTC
 
  The Exchange Agent and DTC have confirmed that the Exchange Offer is eligible
for the DTC Automated Tender Offer Program ("ATOP"). Accordingly, DTC
participants may, in lieu of physically completing and signing the applicable
Letter of Transmittal and delivering it to the Exchange Agent, electronically
transmit their acceptance of the Exchange Offer by causing DTC to transfer
shares of Old Preferred Stock to the Exchange Agent in accordance with DTC's
ATOP 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, which
states that DTC has received an expressed acknowledgment from a participant in
DTC that is tendering shares of Old Preferred Stock which are the subject of
such Book-Entry Confirmation, that such participant has received and agrees to
be bound by the terms of the applicable 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 that the Company may enforce such agreement against such
participant.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their shares of Old Preferred Stock and whose
shares of Old Preferred Stock are not immediately available or who cannot
deliver their shares of Old Preferred Stock or any other documents required by
the Letter of Transmittal to the Exchange Agent prior to 5:00 p.m., New York
City time, on the Expiration Date (or complete the procedure for book-entry
transfer on a timely basis), may tender their shares of Old Preferred Stock
according to the guaranteed delivery procedures set forth in the Letter of
Transmittal. Pursuant to such procedures:

<PAGE>
 
   number or numbers of such tendered shares of Old Preferred Stock, and the
   principal amount of Old Preferred Stock tendered, stating that the tender
   is being made thereby and guaranteeing that, within three business days
   after the Expiration Date, the Letter of Transmittal (or facsimile
   thereof), together with the certificate(s) representing the shares of Old
   Preferred Stock to be tendered in proper form for transfer and any other
   documents required by the Letter of Transmittal, will be deposited by the
   Eligible Institution with the Exchange Agent, and

                                    BUSINESS
 
  Global Crossing is the world's first independent provider of global Internet
and long distance telecommunications facilities and services utilizing a
network of undersea and terrestrial digital fiber optic cable systems. As such,
the Company believes it is the first to offer "one-stop shopping" for its
customers to multiple destinations worldwide. The Company operates as a
"carriers' carrier", providing tiered pricing and segmented products to
licensed providers of international telecommunications services. Capacity on
the Global Crossing Network is offered to all customers on an open, equal
access basis. The cable systems under development by the Company, together with
associated terrestrial capacity, will form a state-of-the-art interconnected
worldwide high capacity fiber optic network: AC-1, an undersea system
connecting the United States and Europe; PC-1, an undersea system connecting
the United States and Asia; MAC, an undersea system connecting the eastern
United States and the Caribbean; PAC, an undersea system connecting the western
United States, Mexico, Panama and the Caribbean; PEC, a terrestrial system,
connecting 18 European cities to AC-1; and GAL a terrestrial system connecting
certain cities in Japan to PC-1. The undersea component of this initial network
totals 51,300 km and the terrestrial component adds 8,400 km for a combined
total of 59,700 km. The Company is in the process of developing several new
cable systems and evaluating other business development opportunities which
will complement the Global Crossing Network.
 
  Global Crossing's business is designed to meet the varying needs of the
global carrier market. The Company offers customers the ability to purchase
capacity on demand, thereby (i) eliminating their need to commit the
substantial capital which would otherwise be required to build cable capacity
and (ii) decreasing the risks associated with forecasting their future capacity
requirements. Compared with traditional cable systems, the Company offers more
comprehensive, flexible and low-cost purchasing alternatives designed to meet
current market requirements of international carriers and licensed Internet
service providers, including direct international city-to-city connectivity,
the ability to purchase capacity periodically and discounts based upon
aggregate volume purchased on the Global Crossing Network.
 
  The Global Crossing Network is being engineered and constructed to allow
multiple upgrades to its initial circuit capacity at a fraction of the initial
system cost, and the Company is exploring opportunities to expand its undersea
and terrestrial systems, as well as the range of the products it offers. The
Company anticipates that its future revenues, beyond those obtained from the
sale of the initial capacity of its first five cable systems, will derive from
several sources. First, each of the currently-planned systems under development
by the Company is upgradeable to capacities significantly beyond the initial
capacity at a fraction of the original system cost. These upgrades can be used
to meet growth in market demand for telecommunications capacity and to achieve
additional revenues. In addition, the Company is currently evaluating a number
of additional undersea and terrestrial cable projects. These potential projects
will be pursued to the extent that they further the Company's strategy of
developing an integrated global network that serves approximately 100 of the
largest metropolitan communications markets worldwide. As the Company's global
network is developed, additional wholesale revenues may be generated from the
sale of additional products and services. See "Risk Factors--Sales of Capacity;
Realization of Other Revenues."
 
  Global Crossing was formed to capitalize on the accelerating growth of
international voice and data telecommunications traffic. The significant
increase in Internet usage and other bandwidth-intensive applications and the
growing use of corporate networks have substantially increased the demand for
international fiber optic cable capacity. The proliferation of
telecommunications service providers due, in large part, to industry
deregulation has further contributed to increased demand for such international
cable capacity. Additionally, the Company believes that other technological
developments, such as improvements in "last mile" access technology, including
xDSL and cable modems, and the increasing video content of Internet
applications, will result in further capacity demand growth.
 
  The Company commenced operations in March 1997, when it contracted for the
construction of AC-1, a 14,000 km digital fiber optic undersea cable system
that will link the United States, the United Kingdom, The Netherlands and
Germany and will initially offer 40 Gbps of service capacity, which is
upgradeable to a minimum of 80 Gbps, increasing the existing undersea fiber
optic cable capacity along the heavily trafficked
 
                                       50
<PAGE>
 
transatlantic route by approximately 65% prior to upgrades. AC-1 commenced
service on its United States-United Kingdom segment on May 26, 1998 and the
full system, encompassing a four fiber pair self-healing ring, is scheduled for
completion by February 1999. In April 1998, Global Crossing contracted for the
construction of PC-1, a 21,000 km digital undersea cable system that will link
the United States and Japan and will initially offer 80 Gbps of service
capacity, upgradeable to a minimum of 160 Gbps. PC-1, a four fiber pair self
healing ring, is scheduled to commence initial service in March 2000. In June
1998, Global Crossing contracted for the construction of MAC, a 9,300 km
digital subsea cable system that will connect New York, the Caribbean and
Florida and will initially offer 20 Gbps of service capacity, upgradeable to a
minimum of 40 Gbps. In addition, in July 1998, Global Crossing contracted for
the construction of PAC, a 7,000 km two fiber pair digital undersea cable that
will connect California, Mexico, Panama and the Caribbean and will initially
offer 20 Gbps of service capacity, upgradeable to a minimum of 40 Gbps.
 
  In addition to the announced segments of the Global Crossing Network, the
Company has made, and expects to continue to make, acquisitions of fiber
capacity which complement its core cable businesses and which address customer
demands for global city-to-city connectivity. Global Crossing intends to pursue
such connectivity in approximately 100 of the largest metropolitan
communications markets worldwide. In October 1998, Global Crossing announced
PEC, a 7,200 km terrestrial system, with 24 to 72 fiber pairs that will link 18
European cities with the United States, Asia and Latin America. The Company
recently obtained a 49% economic interest in GAL, a 1,200 km fiber optic
terrestrial system being developed by Marubeni that among other things, will
connect PC-1 with Tokyo and Osaka. Once completed, the undersea and terrestrial
segments of the Global Crossing Network will form an integrated worldwide
network with multiple access points offering low-cost wholesale capacity.
 
MARKET OPPORTUNITY
 
  The Global Crossing Network is being developed to capitalize on certain
trends in the international telecommunications industry:
 
  Rapid Growth of International Internet and Telecommunications Traffic. While
international voice traffic from 1996-2000 is expected to grow at a rate of 13%
annually, international data traffic growth is expected to significantly
outpace voice traffic growth. One of the key factors contributing to the growth
in data traffic is the increasing use of broadband applications dominated by
the Internet, which has grown at a compound annual rate of 86% for the past
five years as measured by the number of Internet hosts. Reflecting this growth,
the number of ISPs is growing explosively on a global basis. ISPs outside the
United States, particularly in Europe, Asia and Latin America, are expected to
require significant subsea optical circuit capacity to provide efficient
service to their customers to popular Internet web sites in the United States.
In addition, improvements in "last mile" technology, such as xDSL and cable
modems, are contributing to the significant increase in the number of
subscribers using such bandwidth-intensive applications. For example, the
number of cable modem subscribers in the United States alone is projected to
increase by approximately 600% in 1998. Several additional key factors are
expected to drive the rapid growth in worldwide telecommunications traffic,
including:
 
  .  the worldwide growth in the use of bandwidth-intensive applications,
     such as video conferencing and corporate intranets,
 
  .  increased globalization of commerce, and
 
  .  a general decline in international tariffs.
 
  Impact of Global Deregulation. The continued deregulation of the global
telecommunications industry has resulted in a significant increase in the
number of competitors, including traditional carriers, wireless operators, ISPs
and new local exchange service providers, due in large part to:
 
  .  the breadth and volume of privatization activity globally, and
 
  .  the ability of new entrants to compete effectively against the formerly
     protected incumbent providers. This change in the global competitive
     landscape is generating significant demand for broadband communications
     capacity as carriers seek to secure sufficient capacity for their
     expansion plans. As of
 
                                       51
<PAGE>
 
     July 1998, the ITU estimated that there were 1,000 international
     carriers, representing a 181% increase since the end of 1996. In
     addition, further telecom privatization is expected during 1998 and
     1999, which in turn is expected to generate increased global
     competition.
 
  Shortage of Available Capacity. The Company believes that additional network
capacity and faster response times will be required to satisfy current and
anticipated growth in telecommunications traffic. While there has been a
significant increase in the demand for global telecommunications capacity,
there has not been a corresponding growth in the number of new transport
facilities, especially in the undersea cable industry. The Company believes
that construction of competing undersea cable systems will be limited in the
near future due to barriers to entry, including:
 
  .  the extensive lead time required to engineer and construct cable
     systems,
 
  .  the limited number of major undersea cable supply and construction
     companies,
 
  .  the limited number of qualified personnel with extensive experience in
     the undersea cable industry, and
 
  .  the significant capital required to develop undersea cable systems.
 
  Increasing Challenges for Consortia Systems. Historically, the planning and
ownership of undersea cable systems was conducted through large consortia
typically led by the monopoly telecommunications providers. Global Crossing
believes that the consortium approach to constructing, owning and operating
undersea cable systems is becoming far less effective as:
 
  .  carriers increasingly view significant long term capital investments in
     capacity to be a suboptimal utilization of resources,
 
  .  deregulation of international telecommunications markets leads to direct
     competition among consortia members for customers,
 
  .  competition from new entrants makes carriers' market share and capacity
     requirements increasingly difficult to predict, and
 
  .  the rapid pace of technological change creates difficulties in the
     ability of carriers to accurately forecast the growth of
     telecommunications traffic.
 
  Acceptance of Privately Sponsored Cable Systems. The Company believes that
telecommunications service providers have become increasingly receptive to the
advantages of independent, privately-owned cable systems. In connection with
the marketing of capacity on the Global Crossing Network, carriers have
responded positively to the Company's ability to offer:
 
  .  capacity as and when needed without the incurrence of significant
     initial capital investments,
 
  .  a wide range of purchasing options appealing to both established
     carriers and new market entrants,
 
  .  state-of-the-art system quality combined with cost-effective high
     quality operations, administration and maintenance support, and
 
  .  the absence of direct competition with its customers.
 
BUSINESS STRATEGY
 
  Global Crossing's mission is to create the world's first independent global
fiber optic network designed to offer its customers the highest quality city-
to-city communications connectivity among approximately 100 of the largest
metropolitan communications markets worldwide. The principal elements of the
Company's business strategy are to:
 
  Create a Worldwide Network. Upon completion, the currently announced segments
of the Global Crossing Network will directly connect Asia, North America,
Europe, Central America and the Caribbean utilizing state-of-the-art fiber
optic technology. By developing or acquiring terrestrial capacity, we offer
customers low-cost global city-to-city connectivity. The Company also intends
to actively pursue additional opportunities for the expansion and utilization
of the Global Crossing Network, including complementary businesses and
facilities.
 
                                       52
<PAGE>
 
  The Company has entered into contractual arrangements to provide terrestrial
backhaul service between its landing stations in the United States and the
United Kingdom and New York City and London, respectively, as well as other
arrangements to provide terrestrial capacity in Germany and The Netherlands. In
addition, the Company entered into an agreement with Qwest Communications
International Inc. ("Qwest") whereby Global Crossing will receive access to
over 25 U.S. metropolitan communications markets on Qwest's terrestrial network
and is in discussions with other carriers regarding other arrangements for
terrestrial capacity in the U.S.
 
  Additionally, the Company, through PEC plans to provide terrestrial services
to 18 European cities. Furthermore, through GAL, the Company intends to offer
terrestrial services to PC-1 customers from the Company's Japanese landing
stations directly to Tokyo at prices substantially lower than existing
alternatives. The Company has obtained a 49% investment interest in GAL, a
fiber optic terrestrial system being developed by Marubeni which will connect
the PC-1 cable stations with Tokyo and Osaka.
 
  Maintain Position as a Leading Wholesale Service Provider. Global Crossing is
the world's first independent provider of global Internet and long distance
telecommunications facilities and services utilizing a network of undersea and
terrestrial digital fiber optic cable systems. The Company's products are
segmented to meet the varying needs of the global carrier market, with shore-
to-shore capacity offered to major carriers that have their own terrestrial
capacity and city-to-city capacity provided to other customers that require
such service. Global Crossing also offers carriers, through wholesale channels,
a combination of volume-based purchasing flexibility, typically according to a
tiered scale with various incentive levels, and volume discounts for purchases
of capacity on one cable system based upon purchases previously made on the
Company's other systems. See "--Sales and Marketing."
 
  Utilize State-of-the-Art Technology. The Global Crossing Network is being
engineered and constructed using the latest in fiber optic technology, self-
healing ring structures, erbium doped fiber amplifier repeaters, DWDM and
redundancies of capacity to ensure instantaneous restoration. The Company
believes that incorporating such technology in the Global Crossing Network
will:
 
  .  provide a cost advantage over existing alternatives,
 
  .  make it more reliable than competing systems,
 
  .  allow the Company to offer substantially more capacity than existing
     cable systems, and
 
  .  enable the capacity of each of the Company's cable systems to be
     upgraded at the landing stations rapidly and at a fraction of the
     initial system cost without physical modification of the submerged
     portion of the system.
 
  Maintain Position as Low-Cost Provider. The Company plans to maintain its
position as a low-cost provider of facilities and services to its carrier
customers relative to its competitors. Global Crossing believes that this low-
cost position results from a combination of:
 
  .  low sales, marketing and general and administrative costs, reflecting a
     commitment to wholesale customers,
 
  .  ownership of state-of-the-art facilities, resulting in low unit costs
     and low operating and maintenance costs that will be passed on to its
     customers, and
 
  .  purchasing efficiencies.
 
  Provide "One-Stop" Sales and Service. Through both its marketing and sales
force, as well as its ongoing operations, administrative and maintenance
support, Global Crossing plans to offer one-stop sales and service to customers
worldwide. The Company currently employs 19 marketing professionals located in
the Company's headquarters in Bermuda and in major cities throughout the world
in order to facilitate the sales of
 
                                       53
<PAGE>
 
its telecommunications capacity and increase market awareness and name
recognition. See "--Sales and Marketing." The efforts of the sales force have
resulted in significant contractual arrangements to date with international
telecommunications carriers. In addition, Global Crossing is developing a
centralized operations, administration and maintenance support system to serve
the entire Global Crossing Network, including a customer care center, network
operations center and technical support center. Through such integrated
customer support, in combination with its sales force, the Company intends to
enable customers to have a single point of contact regarding capacity sales and
service on the Global Crossing Network.
 
  Leverage Extensive Management Experience. Global Crossing has assembled and
will continue to build a strong management team comprised of executives with
extensive operating experience in the telecommunications industry and the
undersea cable sector. Prior to joining the Company, Jack Scanlon, GCL's Chief
Executive Officer, was President and General Manager of the Cellular Networks
and Space Sector of Motorola, Inc., responsible for approximately $6 billion in
annual revenues and 16,000 employees. Mr. Scanlon has over 30 years of
experience in the telecommunications industry, including 24 years with AT&T and
Bell Laboratories. In addition, William Carter, the Company's senior executive
in charge of system development, was formerly the President and Chief Executive
Officer of AT&T Submarine Systems International ("SSI"), overseeing the
research and development, engineering, implementation and integration of AT&T's
international cable and satellite facilities. Mr. Carter had been at AT&T for
30 years prior to joining the Company. During Mr. Carter's tenure, SSI had the
leading worldwide market share in the undersea cable industry. Dan J. Cohrs,
GCL's Chief Financial Officer, was formerly Vice President and Chief Planning
and Development Officer at GTE, where he was responsible for corporate
development activities, including mergers and acquisitions and strategic
transactions, as well as strategic planning and competitive analysis. In
addition, the Company's system development team includes several individuals
with extensive experience with major undersea cable and telecommunications
industry participants. See "Management."
 
THE GLOBAL CROSSING NETWORK
 
  As part of Global Crossing's mission to create an integrated global, high
capacity fiber optic cable network, the Global Crossing Network is being
engineered and constructed to connect the most heavily trafficked international
corridors in the world via AC-1 (United States to Europe) and PC-1 (United
States to Asia). Furthermore, the Company will provide terrestrial services via
PEC (trans-Europe) and GAL (trans-Japan). Global Crossing plans to interconnect
these systems with two north-south systems (MAC and PAC), directly connecting
the Caribbean, Central America and, through unaffiliated cable systems, South
America. Of the fiber optic cable systems currently being constructed by Global
Crossing, AC-1, MAC, PAC and PEC are wholly-owned projects by the Company,
while PC-1 is being constructed through a joint venture with one or more
partners, principally Marubeni. Global Crossing will initially have
approximately a 58% interest in PC-1 and a 49% interest in GAL and, in
conjunction with Marubeni, will manage their development, sales and operation.

ATLANTIC CROSSING
 
  AC-1, the Company's first undersea fiber optic cable in the Atlantic region,
is a 14,000 km four fiber pair self-healing ring that, upon completion, will
connect the United States and Europe with landing stations in the United
States, the United Kingdom, The Netherlands and Germany. AC-1 is equipped with
state-of-the-art DWDM and the full ring was initially designed to offer 40 Gbps
of service capacity, increasing the existing undersea fiber optic cable
capacity along the heavily trafficked transatlantic route by approximately 65%
prior to upgrades. AC-1 commenced service on its United States-United Kingdom
segment on May 26, 1998, and the full system, encompassing a self-healing ring,
is scheduled for completion by February 1999.
 
  The aggregate costs of AC-1, which are estimated to be approximately $750
million (excluding potential future upgrades), have been fully financed prior
to the offering of Old Preferred Stock. The Company recently entered into a $50
million contract with TSSL to upgrade the capacity on AC-1 from 40 Gbps to 80
Gbps. In addition to the AC-1 Contract with TSSL for construction of the
system, Global Crossing has entered into other contracts with TSSL pursuant to
which TSSL will provide operations, administration and maintenance services for
the system.
 
  The Company has successfully marketed capacity on AC-1 to licensed
telecommunications providers, including PTTs, Internet service providers and
established and emerging telecommunications companies. Sales of capacity on AC-
1 and related backhaul commenced in October 1997 and, as of September 30, 1998,
the Company had entered into CPAs and ICPAs with customers providing for
payments to the Company of $767 million, and $217 million of payments
(including deposits) had been received in respect thereof. These CPAs represent
approximately 30% of the minimum projected sales capacity of 512 circuits on
the AC-1 system. The balance of these payments is scheduled to be collected
over the next four years. The Company's AC-1 customers now total more than 24
international telecommunications carriers, including Deutsche Telekom AG, GTE
Intelligent Network Services Inc., Qwest, Teleglobe Canada Inc., Swisscom, PTT
Telecom BV, Telia AB, Ultraline (Bermuda) Limited and a number of emerging
telecommunications companies. The Company generally grants customers who have
entered into CPAs options to acquire further capacity on AC-1. The amount of
such capacity depends upon a number of factors, including upgrades to AC-1,
future prices for AC-1
 
                                       55
<PAGE>
 
capacity and the amount of unsold capacity on AC-1 at certain dates after the
AC-1 system RFS date. The timing of payments by purchasers under CPAs generally
depends on when service commences on the segment or segments of AC-1 on which
capacity is acquired. All of the foregoing payment amounts assume the
completion of the related segment prior to specified dates falling after the
scheduled RFS date for that segment.
 
  Based upon its current expectations regarding sales of capacity on AC-1, the
Company believes that it will develop and eventually construct AC-2, an
additional four fiber pair cable connecting the United States to Europe. When
combined with AC-1, AC-2 would double the capacity that Global Crossing would
be able to offer customers on the transatlantic route.
 
PACIFIC CROSSING
 
  PC-1, the Company's first undersea fiber optic cable in the Pacific region,
is being developed as a 21,000 km four fiber pair self-healing ring that, upon
completion, will connect California, Washington and two landing sites in Japan,
providing connectivity to other points in Asia through interconnection with
other third party cable systems. PC-1 is designed to operate initially at 80
Gbps of service capacity and to be upgradeable to a minimum of 160 Gbps, using
DWDM technology.
 
  In April 1998, the Company executed the PC-1 Contract with TSSL for the
construction of PC-1, which provides for a system completion date of Summer
2000 at an aggregate cost of approximately $1.2 billion. Equity investments in
PC-1 by Global Crossing and its partners are currently estimated at $400
million (of which $231 million will be provided by the Company), with the
remaining $800 million financed through incurrence of non-recourse indebtedness
at the PC-1 level. The credit agreement for the financing of such indebtedness
was executed on July 30, 1998.
 
MID-ATLANTIC CROSSING
 
  MAC is being developed as a 9,300 km two fiber pair self-healing ring that,
upon completion, will connect New York, the Caribbean and Florida. Global
Crossing intends that MAC will be connected to AC-1 via its cable station in
Brookhaven, New York, providing connectivity between Europe, the eastern United
States and the Caribbean and, through interconnection with other non-Global
Crossing submarine cable systems, South America. MAC is being designed to
operate initially at 20 Gbps of service capacity and to be upgradeable to a
minimum of 40 Gbps using DWDM technology.
 
  In June 1998, the Company executed a contract with Alcatel for the
construction of MAC, which provides for a system completion date of December
1999 at an aggregate cost of approximately $330 million (excluding potential
future upgrades and amounts capitalized with respect to the PCG Warrants), of
which approximately $110 million will be financed by equity contributions by
the Company and $220 million is to be financed through non-recourse
indebtedness at the MAC level. Effective November 25, 1998, MACL obtained $220
million in non-recourse project financing from certain lenders to finance the
initial construction costs of MAC.
 
PAN AMERICAN CROSSING
 
  PAC is being developed as a 7,000 km two fiber pair cable that, upon
completion, will connect California, Mexico, Panama and the Carribean. PAC is
being designed to interconnect with PC-1 through the Company's landing station
in Grover Beach, California and with MAC through the Company's landing station
in St. Croix. It is anticipated that PAC will transverse Panama via an existing
terrestrial right-of-way. PAC is being designed to operate initially at 20 Gbps
of service capacity and to be upgradeable to a minimum of 40 Gbps using DWDM
technology.
 
  In July 1998, the Company executed a contract with TSSL for the construction
of this system which provides for a system completion date of February 2000 and
will cost approximately $475 million (excluding potential future upgrades and
amounts capitalized with respect to the PCG Warrants), with $175 million
 
                                       56
<PAGE>
 
financed through equity contributions from the Company and $300 million to be
financed through non-recourse indebtedness at the PAC level. The contractual
commitment for the financing of such indebtedness was obtained on July 22,
1998.
 
TERRESTRIAL CAPACITY
 
  In addition to the undersea segments of the Global Crossing Network, the
Company has made and expects to continue to construct and to make acquisitions
of terrestrial fiber capacity which complement its undersea cable business and
which address customer demands for global city-to-city connectivity. Global
Crossing intends to provide such connectivity to approximately 100 of the
largest metropolitan telecommunication markets worldwide.
 
  Pan European Crossing. The Company recently announced plans to build PEC
which, upon completion, would offer connectivity to AC-1 and 18 European cities
including London, Paris, Frankfurt, Amsterdam, Rotterdam, Antwerp, Brussels,
Hamburg, Hanover, Dusseldorf, Cologne, Strasbourg and Copenhagen. The Company
also has future plans to connect additional European cities to the system. PEC
is being initially planned as a 7,200 km system with 24 to 72 fiber pairs. The
Company is currently negotiating with various parties for the construction of
PEC and, based on those negotiations, the Company believes that the
construction cost for the system will be approximately $700 million. The
Company will develop PEC in several phases, initially providing connectivity
between 13 cities. The initial phase has an anticipated completion date in the
fourth quarter of 1999. The second phase will add 5 cities and has an
anticipated completion date in 2000.
 
  In October 1998, the Company entered into an agreement with VersaTel Telecom
Europe B.V. ("VersaTel") whereby the Company will secure ownership of optical
fiber conduits on VersaTel's routes connecting Amsterdam, Brussels and the
French border by March 31, 1999 in exchange for capacity and dark fiber on PEC.
This agreement is a key step in securing rights of way for the development of
PEC. In addition, in November 1998, the Company executed an agreement with
Cable & Wireless PLC for the sale of dark fibers on PEC for a purchase price of
approximately $100 million. Furthermore, in November, the Company executed an
agreement with Gas Line for the construction of a portion of PEC located in
Germany. The Company is currently negotiating with other suppliers for the
construction of the remaining portions of PEC.
 
  Global Access. The Company recently obtained a 49% economic interest in GAL,
a fiber optic terrestrial system being developed in Japan by Marubeni that,
among other things, will connect the PC-1 cable stations with Tokyo and Osaka.
Through GAL, the Company intends to offer terrestrial services to PC-1
customers at prices substantially lower than currently available alternatives.
GAL is being initially planned as a 1,200 km system. The Company is currently
negotiating with various parties for the construction of GAL and, based on
those negotiations, the Company believes that the construction cost for GAL
will be approximately $110 million.
 
  Purchased Capacity. The Company has acquired terrestrial connectivity between
its landing stations in the United States and the United Kingdom, in New York
City and London, respectively, as well as entered into other agreements to
provide terrestrial service in Germany and The Netherlands. In addition the
Company entered into an agreement with Qwest whereby Global Crossing may, at
its option, receive access to over 25 U.S. metropolitan communication markets
on Qwest's terrestrial network and is in discussions with other carriers
regarding other arrangements for terrestrial capacity in the U.S.
 
ADDITIONAL NETWORK EXPANSION OPPORTUNITIES
 
  The Company is in the process of planning several new cable systems and
evaluating other business development opportunities which will complement the
Global Crossing Network. There can be no assurance that the Company will
ultimately elect to proceed with such opportunities or, if it elects to do so,
that such opportunities will help the Company achieve and sustain operating
profitability.
 
  Further Undersea Opportunities. The undersea routes served by the Global
Crossing Network and other cable systems are projected to have substantial
growth greatly exceeding all capacity currently in use and under development
(including planned upgrades). To address such demand, the Company plans to
evaluate and, as
 
                                       57
<PAGE>
 
appropriate, build additional systems on such routes. It is anticipated that
such systems, where possible, would be restored on the existing systems and
would achieve further cost efficiencies through the use of existing landing
stations.
 
  Other Development Opportunities. The Company is actively pursuing development
opportunities whereby Global Crossing would provide "fee for service" expertise
in the planning, design, implementation and operation of global undersea cable
systems and associated terrestrial capacity.
 
OTHER ACTIVITIES
 
  Neptune Acquisition. On November 13, 1998, GCL and the Company's indirect
subsidiary GC Pacific Landing Corp. ("GC Pacific Landing") entered into an
agreement and plan of merger (the "Merger Agreement") with Neptune
Communications, L.L.C. ("Neptune") and its wholly-owned subsidiary, Neptune
Communications Corp. ("NCC"). Under the Merger Agreement, GC Pacific Landing
will merge with and into NCC in exchange for 1,052,632 shares of GCL Common
Stock. Neptune is controlled by the Carlyle Group, an international investment
firm ("Carlyle"), and was formed to pursue opportunities in the undersea cable
business. Carlyle's managing director William Conway also serves on GCL's Board
of Directors.
 
  Possible Investments. The Board of Directors of GCL has approved in principle
the making of minority investments in telecommunications and Internet service
providers that do not compete with the Company in its core business and that
will also be current or prospective purchasers of capacity on the Global
Crossing Network. Such investments may consist of purchases of equity
securities for either cash or contributions of capacity on the Global Crossing
Network. Such investments may be managed either by the Company directly or, if
GCL's Board of Directors deems advisable, by one or more third-party investment
advisers so as to minimize potential conflicts of interest and the amount of
time allocated by the Company's senior management to such investments.
 
FINANCING PLAN
 
  As of September 30, 1998, the Company has incurred approximately $708.6
million of the $750 million in total estimated costs for AC-1 (excluding
upgrades). All future costs excluding upgrades with respect to AC-1 are fully
financed.
 
  Global Crossing estimates that the total cost of developing and deploying PC-
1, MAC, PAC, PEC and GAL is approximately $2,815 million (excluding costs of
potential future upgrades and the amounts capitalized with respect to the PCG
Warrants, which is comprised of $1,200 million for PC-1, $330 million for MAC,
$475 million for PAC, $700 million for PEC and $110 million for GAL. Equity
investments in PC-1 by Global Crossing and its partners will be $400 million
(we expect to provide $231 million), with the remaining $800 million of
estimated costs to be financed initially through the incurrence of non-recourse
indebtedness at the PC-1 level. With respect to MAC and PAC the Company
currently anticipates making equity investments of approximately $110 million
in MAC and $175 million in PAC. We expect to finance the remaining estimated
costs, $220 million for MAC and $300 million for PAC, through the incurrence of
non-recourse indebtedness at the project level. We anticipate that additional
financing will be required for AC-2 and other network expansion opportunities
currently under evaluation. Global Crossing has historically been able to
secure indebtedness for its systems for at least 65% of system costs and
intends to finance its future expansion opportunities in a similar fashion. The
actual amounts of our future capital requirements will depend on certain
factors including the cost of developing our cable systems, the speed of
developing our systems and the pricing of our services. There can be no
assurance that financing for such systems will be available to us or, if
available, that such financing can be obtained on a timely basis and on
acceptable terms. See "Risk Factors--Substantial Future Capital Requirements"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

SYSTEM PERFORMANCE
 
  AC-1, PC-1, MAC, PEC and GAL are each designed utilizing self-healing ring
technology to optimize system performance. Two types of protection switching,
span switching and ring switching, are provided. Span switching protects a
system against failures between adjacent landing sites which only affect
service line traffic and not the protection fibers. Ring switching protects a
system against complete failures between adjacent landing sites. Because such
technology will protect any single system failure in less than 500
milliseconds, no outages will result as a consequence of a single system
failure. Accordingly, the estimated system availability on any point-to-point
link on such systems is 99.995%.
 
  As undersea and terrestrial cable systems become more powerful (i.e., carry
more traffic along their transmission paths), it is important to provide a
"self-restoration solution" because other systems do not have the capacity to
provide restoration for these new high performance cable systems. Single span
systems must enter into reciprocal arrangements with either other fiber-optic
operators or satellite carriers to pick up and deliver this traffic if a system
failure should occur. Providing self-restoration through this ring design with
the switching techniques described above is now viewed as offering a
qualitative advantage over single span systems with external restoration.
 
  With respect to PAC, which does not employ self-healing ring technology, the
Company is exploring options to enter into restoration arrangements with
terrestrial fiber optic cable operators to protect against system traffic
interruptions. The Company may also enter into similar arrangements to protect
against catastrophic system malfunction on its other cable systems.
 
SALES AND MARKETING
 
  The Company markets capacity on its systems to licensed telecommunications
providers, including PTTs, Internet service providers and established and
emerging telecommunications companies. The Company believes its current
customers represent a broad array of telecommunications companies.
 
  The initial sales strategy of the Company emphasizes the sale of capacity on
an IRU basis, whereby the customer purchases a unit of capacity for the
remaining design life of a particular cable system. On AC-1, the Company is
selling capacity at an increment of 155 megabits (Mbps), known as an STM-1, for
the 25-year life of AC-1. For the other Global Crossing cable systems, the
Company also expects to sell capacity to customers at the STM-1 level, and
smaller increments, where warranted based upon the actual demand levels along
certain routes. The Company has instituted a tiered pricing schedule for all of
its systems which provides for volume discounts, thereby allowing customers to
reduce their average circuit cost as more circuits are purchased. In addition,
the Company offers pricing discounts on purchases of capacity prior to a
system's commercial operation date, in order to induce customers to make early
purchase commitments.
 
  To further increase the attractiveness of the Company's network, Global
Crossing intends to make selective wholesale acquisitions of terrestrial
capacity, thereby enabling customers to achieve city-to-city connectivity
through the Global Crossing Network at prices significantly lower than if such
customers had attempted to gain such connectivity by separately purchasing such
terrestrial capacity. For AC-1 customers, the Company entered into contractual
arrangements providing terrestrial capacity between its landing stations in the
United States and the United Kingdom, and New York City and London,
respectively. In addition, Deutsche Telecom and KPN provide terrestrial
capacity directly to the Company's AC-1 customers in Germany and The
Netherlands, respectively. In addition, the Company has entered into an
agreement with Qwest whereby Global Crossing will receive access to over 25
U.S. cities on Qwest's terrestrial network and is in discussions with other
carriers regarding other arrangements for terrestrial capacity in the U.S.
Furthermore, the Company through PEC plans to provide terrestrial connectivity
to 18 European cities.
 
  Global Crossing is exploring the development of other products designed to
take advantage of its ownership of several cable systems in different parts of
the world. For example, the Company has offered its customers volume discounts
for purchases of capacity on one system based upon purchases previously made on
 
                                       59
<PAGE>
 
the Company's other systems and the ability to transfer a portion of unused
capacity purchases from one Global Crossing system to another depending on
customers' individual traffic needs. The Company also offers customers multi-
year CPAs for capacity across the entire Global Crossing Network at tiered
pricing.
 
  The Company's marketing entity, Global Crossing International, was
established to facilitate the sales of communications capacity on the Global
Crossing Network, as well as to increase market awareness and name recognition
of Global Crossing. Global Crossing has been able to recruit and train a full-
service sales and marketing team, including Mr. Jack Finlayson, President of
Global Crossing International, a former senior executive of Motorola who
recently joined the Company, and Mr. Patrick Joggerst, Vice President,
Worldwide Sales and Marketing, who had been at TSSL and AT&T for a total of 17
years prior to joining the Company, most recently as Managing Director of
TSSL's Americas Region. Mr. Joggerst directly oversees the Americas Region and
is responsible for overseeing the duties of the two regional vice presidents,
each being in charge of one of the two other regions of the Company's marketing
organization, Europe/Middle East/Africa and Asia. Each regional vice-president
oversees the performance of regional marketing directors who have direct
account responsibility in certain geographic areas of the region. In total, the
Company employed 19 marketing professionals as of September 30, 1998. While the
Company intends to expand the current size of its marketing organization,
management believes that a moderately-sized sales force is sufficient to
adequately address all customers seeking to acquire undersea cable capacity on
a wholesale basis.
 
  During the pre-operational period for AC-1, in which the Company sought to
generate significant pre-sales of capacity, the Company presented project
information meetings (otherwise known as data gathering meetings) in order to
better educate potential customers about AC-1 and Global Crossing's other
planned cable systems. Attendees of such meetings have been affiliated with
both existing and prospective customers and have represented a variety of
sectors of the telecommunications industry. Ongoing, the Company intends to
organize at least one major international conference per year in order to
provide updated information on the Global Crossing Network. The Company also
intends to host regional project information meetings focusing on a particular
cable system, with such meetings scheduled to precede the anticipated
commercial operation date for such system.
 
  The Company intends to reinforce customer awareness through a variety of
marketing campaigns, including its Global Crossing international conferences
and regional marketing events, participation in key industry and user group
conferences, speaking engagements, press conferences and promotional campaigns.
In addition, Global Crossing expects its marketing team to periodically visit
current and prospective customers to obtain a greater understanding of the
individual needs of such customers.
 
SUMMARY OF PRINCIPAL TERMS OF STANDARD CONTRACTUAL DOCUMENTATION
 
Capacity Purchase Agreements (CPAs)
 
  In general, a CPA provides for the sale of capacity by the Company on an IRU
basis, whereby the purchaser owns a unit of capacity for the remaining design
life of a particular system. The term of a CPA is 25 years from the RFS date
for the system on which capacity is being acquired, which is the entire useful
life of the system. Upon execution of a CPA prior to a segment RFS date, the
Company generally receives 10% of the purchase price immediately, with the
balance of the purchase price due to the Company upon the applicable RFS date
for that segment. A limited number of CPAs provide for payment of the purchase
price in installments over two to four year periods. Each purchaser under a CPA
is required to pay its allocated share of the cost of operating, maintaining
and repairing the system. A purchaser's payment obligation under a CPA shall
generally terminate with respect to any purchased capacity on AC-1 other than
the United States-United Kingdom segment (and, in some cases, with respect to
purchased capacity on the United States-United Kingdom segment), if the RFS
date for the AC-1 system has not occurred by June 30, 1999. Performance under
CPAs is also contingent upon the obtaining and continuance of such approvals,
consents, governmental authorizations, licenses and permits as may be required
or reasonably deemed necessary by each party thereto for performance by such
party thereunder and as may be satisfactory to it. The obligations of
purchasers under
 
                                       60
<PAGE>
 
certain CPAs are additionally contingent upon the execution of related ICPAs.
See "Risk Factors--Sales of Capacity; Realization of Other Revenues" and "--
Termination of Capacity Purchase Agreements."
 
  Additionally, each purchaser acquiring capacity on AC-1 prior to the system
RFS date is granted the right to receive additional capacity ("residual
capacity") at no additional cost upon the date which is 12 1/2 years after the
RFS date for the system. Furthermore, neither party is liable to the other for
consequential, incidental, indirect or special damages sustained by reason of
(i) any failure in or breakdown on the system or the facilities associated with
the system, (ii) the failure of any inland carrier to perform the terms and
conditions of any agreement to which it and the purchaser are parties or (iii)
for any interruption of service, whatever the cause and however long it shall
last. Each CPA is subject to an arbitration clause. Some CPAs are supported by
a parent guarantee from the purchaser.
 
Inland Services Agreements (ISAs)
 
  The Company has entered into agreements with certain terrestrial fiber cable
systems to purchase inland capacity on such systems for resale to its
purchasers. In general, the term of each ISA is 25 years from the RFS date of
the particular system or until the system is retired, whichever occurs first.
In certain cases, the Company has the option to extend the term of each ISA for
an additional five years. Neither party to an ISA is responsible for any loss,
damage, delay or failure of performance resulting from an event of Force
Majeure (as defined therein). If an event of Force Majeure continues for a
period of 30 days, the Company may terminate the ISA. Each ISA is subject to an
arbitration clause.
 
Inland Capacity Purchase Agreements (ICPAs)
 
  The Company has entered into ICPAs with some of its customers. Under an ICPA,
the Company provides the customer with a portion of the terrestrial capacity it
purchased from owners of terrestrial cable systems under ISAs. The term of each
ICPA is 25 years from the RFS date for the particular system. Upon execution of
an ICPA, the Company generally receives 10% of the purchase price immediately,
with the balance due no later than the RFS date for the particular segment. A
limited number of ICPAs provide for payment of the purchase price in
installments over two to four year periods. A purchaser's payment obligation
under an ICPA generally shall terminate with respect to any purchased capacity
on AC-1 other than the United States-United Kingdom segment (and, in some
cases, with respect to purchased capacity on the United States-United Kingdom
segment), if the RFS Date for the AC-1 system has not occurred by June 30,
1999. Unlike a CPA, the purchaser under an ICPA is generally not required to
make any additional payments for costs associated with operating, maintaining
and repairing the terrestrial capacity in which the IRU is granted. Neither
party is liable to the other for consequential, incidental, indirect or special
damages sustained (i) by reason of any failure of any inland carrier to perform
the terms and conditions of any ISA to which it is a party or (ii) for any
interruption of service, whatever the cause and however long it shall last.
Each ICPA is subject to an arbitration clause. An ICPA may be supported by a
corresponding parent guarantee from the purchaser.
 
OPERATIONS, ADMINISTRATION AND MAINTENANCE SUPPORT
 
  Pursuant to the AC-1 OA&M Agreement, TSSL will provide operations,
administration and maintenance support on behalf of AC-1 for a term of eight
years following the commencement of commercial operations. As of September 30,
1998, the Company was committed under the AC-1 OA&M Agreement to make payments
totaling approximately $254 million. Such agreement is extendible at the option
of the Company for two additional periods of 8.5 years each. For AC-1, TSSL's
network operations center is designed to ensure the overall ongoing monitoring
of the system's operation, maintenance and control systems. The network
management equipment located at the Brookhaven, New York landing station
provides fault management, security management, configuration management and
performance management, while undersea network management equipment located at
all landing stations provides system level monitoring of the undersea
terminating equipment. The full integration of these control elements allows
the AC-1 cable system to be "self-diagnostic," with such control elements
facilitating localization and repair in the event of the occurrence of a system
fault.
 
                                       61
<PAGE>
 
  In addition, Global Crossing is separately developing a worldwide operations,
administration and maintenance support system to serve each of its cable
systems (exclusive of AC-1 for the initial term of the TSSL OA&M Agreement).
Such support will be handled through three work centers: a customer care center
("CCC"), network operations center ("NOC") and technical support center
("TSC"). It is currently anticipated that the CCC will be located in Bermuda
and both the NOC and TSC will be located in Europe.
 
  Customer Care Center. The CCC will provide capacity purchasers with a single
point of contact for service provisioning, interconnect coordination support
and billing inquiries.
 
  Network Operations Center. The NOC will handle operations, administrative and
maintenance activities for each of the Company's cable systems, including
capacity provisioning, network performance, repair and restoration activities.
Capacity provisioning relates to the appropriate allocation of capacity on the
Company's cable systems among capacity purchasers. Management of network
performance entails detection and response to system degradation and other
performance parameters, as well as preventative activities.
 
  Technical Support Center. The TSC will be a 24-hour center managed by highly-
trained experts to handle technical inquiries from purchasers regarding system
performance and interconnection arrangements.
 
COMPETITION
 
  The international telecommunications industry is highly competitive. The
Company faces competition from existing and planned cable systems along each of
its planned routes and from satellite providers, including existing
geosynchronous satellites and low-earth orbit systems now under construction.
The Company competes primarily on the basis of price, availability,
transmission quality and reliability, customer service and the location of its
systems. Traditionally, carriers have made long term investments in ownership
of cable capacity, making lower price and superior service less determinative
in convincing such carriers to acquire additional capacity on the Company's
systems than is the case in industries without such long-term relationships.
See "Risk Factors--Competition."
 
 Existing and Planned Cable Systems
 
  The routes addressed by Global Crossing's planned systems are currently
served by several cable systems as well as satellites. Currently, there are
several fiber optic transatlantic cable systems, each of which will compete
directly with AC-1. Primary future sources of transatlantic competition for the
Company may result from, among others, (i) TAT-14, a transatlantic cable system
which is being developed by its consortium members, including British Telecom,
AT&T, France Telecom and Deutsche Telekom, and (ii) Gemini, a transatlantic
cable system being operated and marketed by MCI WorldCom, Inc. and Cable &
Wireless PLC. The Company believes that such other cable systems will compete
directly with AC-1 and the commitments of the developers and other carriers on
these systems could substantially reduce demand for capacity on AC-1.
 
  Similarly, there are several cable systems currently operating between the
United States and Asia, the route to be served by PC-1. Competition in the
transpacific market may result from, among others, (i) China-US, a transpacific
system being developed as a "private cable system" by fourteen large carriers,
including SBC, MCI, AT&T and Sprint, most of whom have traditionally sponsored
consortium cables and (ii) Japan-US, a transpacific system being developed by a
consortium of major telecommunications carriers, including MCI WorldCom, AT&T,
KDD, NTT, Cable & Wireless PLC and GTE. Although the Company believes that such
other cable systems will not satisfy the demand for capacity between the United
States and Japan and that there is currently enough demand projected to
accommodate all such systems, such other cable systems will receive commitments
for capacity that PC-1 could have received in their absence.
 
  In addition, the Company will face competition on its planned trans-European
network. There are several carriers, including Viatel, KPN-Qwest, MCI WorldCom,
Inc., a joint venture between Deutsche Telekom and France Telecom, British
Telecom and Hermes, who are currently planning or building trans-European
network assets.
 
                                       62
<PAGE>
 
  Other regional and global systems are being considered by developers,
including Project Oxygen, a global system being evaluated by CTR Group, Ltd. In
addition, the Company may face competition from existing and planned regional
systems and satellites on its MAC and PAC routes, where entrants are vying for
purchases from a small but rapidly growing customer base.
 
 Satellite Transmission
 
  When comparing cable transmission against satellite transmission, the Company
believes that cable has a distinct advantage with respect to latency (i.e.,
transmission delay) and voice quality. Cable transmission has a lower cost per
circuit, higher capacity and longer expected equipment life than satellite
transmission. Satellite transmission is generally considered to have a
comparative advantage versus cable transmission for mobile communications only
in the area of 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.
 
  In early 1997, the FCC granted Ka-band licenses and orbital locations to 13
companies. The firms developing future satellite technology envision a network
of satellites that will provide broadband data transmission with data rates of
2 Mbps, 20 Mbps, and even 155 Mbps. Potential participants in the field include
Astrolink, Skybridge, Teledesic Corporation, CyberStar and SpaceWay, who are
seeking to provide high bandwidth transmission sublet networks. Due to (i) the
significant initial costs related to these systems, (ii) the risks relating to
satellite launch systems and (iii) the significantly lower transmission
capacity versus current fiber optic systems, the Company believes that the new
satellite systems will not be able to offer competitive cost per unit of
transmission capacity in the dense metropolitan markets the Company is
targeting. Further, the Company believes it will have at least five years lead
time to help it solidify a sustainable competitive market position before true
broadband satellite service commences.
 
SUPPLIERS
 
  There are currently three major supply companies in the undersea cable
industry: TSSL, Alcatel and KDD SCS. Cable & Wireless PLC and Pirelli also have
a presence in the industry and there are a number of smaller suppliers who have
focused primarily on regional routes or non-repeatered systems. TSSL is
completing construction of AC-1, is responsible for the design and installation
of PAC and, together with KDD SCS (as a subcontractor), is responsible for
design and installation of PC-1. Alcatel is responsible for design and
construction of MAC. See "Risk Factors--Dependence on Third Parties."
 
PROPERTIES
 
  The Company leases executive and administrative offices at its worldwide
headquarters at Wessex House, 45 Reid Street, Hamilton HM12 Bermuda. The
Company owns a cable station in Brookhaven, New York and a cable station in
White Sands, United Kingdom. The Company leases cable station space in Sylt,
Germany and cable station space in Beverwijk, The Netherlands. Such leases run
for the anticipated 25-year term of AC-1. The Company also leases office space
in Amsterdam, Los Angeles, Morristown, New Jersey, Dallas, London, San
Francisco, New York, Coral Gables, Florida and Buenos Aires, Argentina.
 
REGULATION
 
  The Company, in the ordinary course of development, construction and
operation of its fiber optic cable systems, will be required to obtain and
maintain various permits, licenses and other authorizations in both the United
States and in foreign jurisdictions where its cables land, and will be subject
to applicable telecommunications regulations in such jurisdictions. In
particular, submarine cable landing or similar licenses will be required in
many of the jurisdictions where Global Crossing's planned systems will land.
With respect to AC-1, an undersea cable landing license (the "AC-1 Landing
License") and a subsequent modification have been obtained from the United
States Federal Communications Commission ("FCC"), which license permits AC-1 to
land in the United States at the Brookhaven, New York landing site and to
operate between the United
 
                                       63
<PAGE>
 
States, the United Kingdom, The Netherlands and Germany. The AC-1 Landing
License authorizes the Company to provide capacity on a private carriage basis,
and AC-1 is not presently regulated by the FCC as a common carrier. Global
Crossing has obtained landing licenses similar to the AC-1 Landing License in
each of the other jurisdictions where the AC-1 cable system will land and where
such licenses are required. With respect to each of the Company's cable systems
other than AC-1, the Company anticipates both filing applications for cable
landing licenses with the FCC (and, where necessary, foreign regulatory
agencies) and seeking private carriage status for these systems as well. These
licenses are typically issued for a term of years (in the case of the FCC-
issued cable landing license, 25 years), and are subject to renewal. United
States law (and the law of several foreign jurisdictions, as well) limits
foreign ownership, direct or indirect, of entities holding cable landing
licenses, although the FCC has progressively relaxed to the rules to examine
only those foreign holders that are affiliated with a foreign
telecommunications carrier that has market power in the destination country.
More recently, in order to implement a multilateral World Trade Organization
agreement, the FCC adopted regulations that presumptively permit unlimited
foreign ownership by nationals of countries that are party to that agreement.
See "Risk Factors--Effect of Government Regulation."
 
  Construction of each of the Company's cable systems also requires the
acquisition and maintenance of various permits and licenses in the ordinary
course of business. Pursuant to its construction contracts for AC-1 and PC-1,
TSSL is contractually obligated to obtain and maintain all such licenses and
permits. Although Global Crossing intends that the construction contracts for
each of the Company's other planned cable systems will impose the burden of
acquiring and maintaining construction licenses and permits on the contractor
for each of such systems, there can be no assurance that such contractor will
successfully obtain such permits and licenses. See "Risk Factors--Risks Related
to Completing our Cable Systems."
 
EMPLOYEES
 
  As of September 30, 1998, the Company had approximately 125 employees. The
Company considers its relations with its employees to be good.
 
LEGAL PROCEEDINGS
 
  The Company is not presently subject to any material legal claims or
proceedings.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS
 
  The 1998 Global Crossing Ltd. Stock Incentive Plan (the "Stock Incentive
Plan") provides that, upon a "change in control," certain of the awards granted
under the Stock Incentive Plan will vest immediately. A "change in control" is
defined under the Stock Incentive Plan as the occurrence of any of the
following: (i) any Person (other than a Person holding securities representing
10% or more of the combined voting power of GCL's outstanding securities as of
July 15, 1998, GCL, any trustee or other fiduciary holding securities under an
employee benefit plan of GCL, or any company owned, directly or indirectly, by
the shareholders of GCL in substantially the same proportions as their
ownership of stock of GCL) becomes the beneficial owner (as defined under Rule
13d-3 under the Exchange Act) of securities of GCL (a) in excess of the
interest held by the existing shareholders of GCL as of July 15, 1998 and (b)
representing 30% or more of the combined voting power of GCL's then outstanding
securities; (ii) during any period of 24 months, individuals who at the
beginning of such period constitute the board of directors and any new director
(other than those directors who meet certain exceptions specified in the Stock
Incentive Plan) whose election was approved in advance by a vote of at least
two-thirds of the directors then still in office, cease for any reason to
constitute at least a majority of the board of directors; (iii) the
shareholders of GCL approve any transaction under which GCL is merged or
consolidated with any other company, other than a merger or consolidation which
would result in shareholders of GCL immediately prior thereto continuing to own
more than 65% of the combined voting power of the voting securities of GCL or
such surviving entity; or (iv) the shareholders of GCL approve a plan of
complete liquidation of the company or an agreement for the sale or disposition
by GCL of all or substantially all of GCL's assets, other than the liquidation
of GCL into a wholly-owned subsidiary.
 
  GCL has entered into an employment agreement, dated as of April 1, 1998, with
Mr. Jack Scanlon, providing for Mr. Scanlon's employment as GCL's Chief
Executive Officer for a term of two years and continuing thereafter for
successive two-year terms unless either GCL or Mr. Scanlon provides at least
three months' notice in advance of the expiration of the current term. In
connection with such agreement, Mr. Scanlon was issued an option to purchase a
total of 1,800,000 shares of GCL Common Stock at an exercise price of $1.67 per
share. Such options vest in 25% increments upon the first day of employment and
at the end of each of the first three years of Mr. Scanlon's employment with
GCL. Upon a "change of control", as defined in the Stock Incentive Plan, or any
other "non-fault" termination as defined in Mr. Scanlon's employment agreement,
vesting of all of
 
                                       73

grants Mr. Finlayson the option to sell 150,000 shares of GCL Common Stock to
the Company at $13.33 per share after two years of employment.

providing for his services as GCL's managing director. In connection with such

                              CERTAIN TRANSACTIONS
 
GENERAL
 
  GCL and Global Crossing have entered into certain transactions described
below with entities affiliated with GCL and Global Crossing and their officers
and directors.
 
TRANSACTIONS WITH PACIFIC CAPITAL GROUP (PCG) AND ITS AFFILIATES
 
  GCL and Global Crossing have entered into certain transactions with PCG and
its affiliates, including PCG Telecom Services LLC ("PCG Telecom") and Ocean
Systems International LLC ("OSI"), in connection with the development by PCG
and its affiliates of several of Global Crossing's systems, including AC-1, PC-
1, PAC and MAC. The Board of Directors of GCL decided to assume the ongoing
development of systems (other than AC-1) from OSI. Revenue from GCL comprises
the sole source of revenues for PCG Telecom. PCG and its affiliates are
controlled by Mr. Gary Winnick, the Co-Chairman of the Board of Directors of
GCL, and certain other officers and directors of GCL are affiliated with PCG,
including Messrs. Cook, Lee, Porter and Brown. See "Management" and "Principal
Shareholders."
 
  Advisory Services Agreements. ACL entered into an Advisory Services
Agreement, dated as of March 25, 1997 (as amended, the "AC-1 Advisory
Agreement"), with PCG Telecom with respect to AC-1. Under the AC-1 Advisory
Agreement PCG Telecom was entitled to an advisory fee of 2.0% of the gross
revenues of ACL. The Board of Directors of GCL agreed that each other direct
subsidiary of GCL shall from time to time enter into, or cause each of its
subsidiaries to enter into, similar Advisory Services Agreements (together with
the AC-1 Advisory Agreement, the "Advisory Services Agreements") with PCG
Telecom, providing for an advisory services fee of 2% of such subsidiary's
gross revenues (not double counting any portion of intercompany revenues on
which the advisory services fee has already been calculated). The aggregate
amount of all advisory fees payable under the Advisory Services Agreements was
to be reduced by the amount, if any, by which principals of PCG received cash
compensation (as opposed to reimbursement of expenses) from GCL other than cash
compensation paid to such principals in their capacities as officers or
directors of GCL as approved by the Board of Directors. In addition, until the
earlier of (i) the date GCL had a public equity market value in excess of
$1.5 billion and (ii) March 25, 2002 (such earlier date, the "Deferred Fee
Payment Date"), the aggregate cumulative amount of the fees paid under the
Advisory Services Agreements in respect of the calendar years prior to and
including each calendar year set forth below was not to exceed the amounts set
forth below, with any excess being deferred and paid (together with interest
thereon at a rate per annum equal to LIBOR) on the Deferred Fee Payment Date:
1998--$10 million; 1999--$20 million; 2000--$30 million; and 2001--$40 million.
 
  Amounts payable under the AC-1 Advisory Services Agreement were to be divided
annually in the following manner: 90% of the initial $5 million in advisory
services fees was retained by PCG Telecom, 5% of the initial $5 million in
advisory service fees was payable to ULLICO, Inc. ("ULLICO"), which is the
ultimate parent of MRCo, Inc., and 5% of the initial $5 million in advisory
service fees was payable to PCG. With respect to amounts over the initial $5
million annually in advisory services fees, 15.5% was payable to ULLICO, 15.5%
was payable to PCG, 35% was payable to CIBC and the remaining 34% is retained
by PCG Telecom. Amounts retained by PCG Telecom, after deducting associated
expenses incurred by PCG relating to salaries, bonuses, overhead and an annual
discretionary expense reduction, were divided amongst Messrs. Winnick, Brown,
Lee, and Porter in the following percentages: 40%, 15%, 22.5%, and 22.5%,
respectively.
 
  All amounts payable annually under each of the other Advisory Services
Agreements was to be retained by PCG Telecom and, after deducting associated
expenses incurred by PCG relating to salaries, bonuses, overhead and an annual
discretionary expense reduction, divided amongst Messrs. Winnick, Cook, Brown,
Lee, and Porter in the percentages: 50%, 8%, 12%, 15%, and 15% respectively.
 
  GCL acquired the rights to advisory fees payable under the Advisory Services
Agreements on the behalf of the Company in consideration for the issuance,
through PCG Telecom, to the persons entitled to receive such
 
                                       77

fees of shares of GCL Common Stock having an aggregate value of $135 million
(based upon the Price to Public per Share ($19.00) payable in the GCL Stock
Offerings) and the cancellation of approximately $2.7 million owed to the
Company under a related advance agreement (the "Advisory Services Agreement
Termination"). Concurrently with the GCL Stock Offerings, all of the
obligations of GCL and ACL in respect of the Advisory Services Agreements were
terminated. GCL obtained a fairness opinion from an independent financial
advisor in connection with this transaction. As a result of this transaction,
the Company incurred a charge of approximately $137.7 million which has been
reflected in its statement of operations for the period ended June 30, 1998. Of
this amount, $135 million was determined by applying the 2% advisory fee to
projected revenues for the Company's systems. The present value of the
aggregate advisory fees was then calculated at $155.5 million, using a discount
rate of 12% in respect of AC-1 and 15% in respect of systems other than AC-1.
This amount was subsequently reduced to $135 million. Both the discount rates
and the ultimate valuation were determined as a result of a negotiation process
including a disinterested director of GCL and the various persons entitled to
fees under the Advisory Services Agreements. The shares of GCL Common Stock
issued in connection with the Advisory Services Agreement Termination were
issued to the following persons in the following amounts:

  PCG Warrants. Old GCL and PCG entered into a warrant agreement, dated as of
January 21, 1998 (the "PCG Warrant Agreement"), pursuant to which Old GCL
issued PCG three separate warrants (collectively, the "PCG Warrants") providing
PCG with the right to purchase (i) 9,226,592 of Old GCL's Class B Shares for an
aggregate purchase price of $50,000,000; (ii) an additional 4,613,297 of Old
GCL's Class B Shares for an aggregate purchase price of $31,250,000; and (iii)
an additional 4,613,297 of Old GCL's Class B Shares for an aggregate purchase
price of $37,500,000. Such PCG Warrants would entitle PCG to acquire an
additional 10% of the capital stock of Old GCL (as of the date of issuance of
the PCG Warrants), with the exercise price of each PCG Warrant based upon a
different market valuation of the Company. In connection with issuance of the
PCG Warrants, the PC-1, MAC and PAC systems (then under development) were
acquired by the Company, as was the development team that had been assembled by
Pacific Capital Group (led by William Carter, former President of SSI and Wally
Dawson, former Senior Vice President of SSI). The exercise of each of the PCG
Warrants was conditioned upon (i) an initial public offering of shares of Old
GCL (or any successor thereto), underwritten by an investment banking firm of
national reputation (as determined by a majority of the Board of Directors of
Old GCL) from which Old GCL shall have received at least $50,000,000 in net
proceeds, (ii) the investment by Old GCL in the aggregate of at least
$500,000,000 of Net Attributable Capital (as defined below) in cable systems
other than AC-1 and (iii) the generation in the aggregate by cable systems
other than AC-1 of at least $100,000,000 in Net Attributable Revenues (as
defined below). For purposes of the PCG Warrant Agreement, with respect to any
cable system, (i) "Net Attributable Capital" means the aggregate debt and
equity capitalization of such system multiplied by the percentage ownership of
Old GCL (directly or indirectly) in such system, and (ii) "Net Attributable
Revenues" means the net revenues of such system multiplied by the percentage
ownership interest of Old GCL (directly or indirectly) in such system. Rights
under each of the PCG Warrants were divided amongst Messrs. Winnick, Cook,
Brown, Lee and Porter in the following percentages: 50%, 8%, 12%, 15% and 15%,
respectively.
 
  The Board of Directors of Old GCL determined that upon the successful
completion of the GCL Stock Offerings the conditions precedent to exercising
the PCG Warrants were met and therefore the PCG Warrants were deemed
exercisable. The Board of Directors of Old GCL also amended the terms of the
PCG Warrants to
 
                                       78
<PAGE>
 
give each holder the option to convert each share under warrant into a fraction
of a Class B Share based upon the ratio of the current per share valuation at
the time of conversion less the per share exercise price of the warrant divided
by the current per share valuation at the time of conversion multiplied by the
number of warrants to be converted, together with a new warrant ("New PCG
Warrants") to purchase the remaining fraction of such Class B Share at an
exercise price equal to the Price to Public per Share ($19.00) payable in the
GCL Stock Offerings. The New PCG Warrants will terminate on August 13, 2003,
five years from the date of issuance. Prior to the GCL Stock Offerings, PCG
converted the PCG Warrants in such manner into Class B Shares and New PCG
Warrants, utilizing the anticipated price of the GCL Stock Offerings as the
current per share valuation for such purposes, with the Company assuming the
obligations of Old GCL under the New PCG Warrants (the "PCG Warrant
Conversion"). Upon the PCG Warrant Conversion, Messrs. Winnick, Cook, Brown,
Lee and Porter transferred 100,000, 25,000, 25,000, 25,000 and 25,000 New PCG
Warrants, respectively, to Nelson S. Zand, an employee of PCG.
 
  Following such transactions, shares of GCL Common Stock and New PCG Warrants
issued in connection with the conversion of the PCG Warrants were issued to the
following persons in the following amounts:

  Advance Agreements. GCL entered into an Advance Agreement, dated as of March
24, 1998 (the "AC-1 Advance Agreement"), with PCG Telecom, pursuant to which
GCL agreed to make advances to PCG Telecom within three days of a written
request from PCG in respect of fees owing to PCG Telecom under the AC-1
Advisory Agreement in an amount not to exceed 1% of the amounts payable under
long-form capacity purchase agreements executed by ACL. As security for the
obligation of PCG Telecom to repay such advances, PCG Telecom granted a
security interest to GCL in its rights to receive payments under the
AC-1 Advisory Agreement. The AC-1 Advance Agreement was terminated and the
obligation of PCG Telecom to repay approximately $2.7 million to the Company
thereunder cancelled in connection with the termination of the Advisory Service
Agreements discussed above.
 
  Of the $4,669,340 advanced to PCG Telecom under the AC-1 Advance Agreement,
the following amounts were paid to directors, executive officers and
shareholders of GCL:

TRANSACTIONS WITH WORLDPORT
 
  On April 7, 1998, the Company entered into a CPA with Worldport
Communications, Inc. ("Worldport"), whereby Worldport acquired a total of five
STM-1s of capacity on AC-1 in a transaction that occurred in the ordinary
course of business of the Company and on terms and conditions no less favorable
to the Company than those contained in its other CPAs. Worldport also executed
an MOU to purchase capacity on PC-1, PAC and MAC. Certain officers and
directors GCL, including Mr. Winnick, Mr. Cook, Mr. Scanlon, Mr. Lee, Mr.
Porter, Mr. Brown, Mr. Raben, Mr. Bloom, Mr. Kehler and Mr. Steed, have direct
or indirect equity ownership positions in Worldport aggregating approximately
10% of the current common stock of Worldport. In addition, Continental Casualty
Corporation, with which Mr. Weinberger is affiliated, holds warrants to
purchase common stock in Worldport aggregating less than 1% of the current
common stock of Worldport and has also engaged in certain debt financing
transactions with Worldport. Campuslink Communications Systems Inc., a private
company which provides telecommunications services to colleges and universities
and which is indirectly majority-owned by Mr. Winnick and Union Labor Life
Insurance Company, an affiliate of MRCo, Inc., has reached an agreement in
principle to be acquired by Worldport. In addition, in connection with the
Company's recent decision to explore the making of minority investments in
telecommunications and Internet service providers that are current or
prospective customers on the Global Crossing Network, the Company is
 
                                       80
<PAGE>
 
considering an investment in Worldport. If the Company chooses to make such
investment, it is currently anticipated that such investment would amount to
approximately $10 million of cash and two STM-1 circuits on AC-1.
 
TRANSACTIONS WITH TELECOMMUNICATIONS DEVELOPMENT CORPORATION
 
  Prior to the GCL Stock Offerings and after giving effect to the Old GCL
Exchange, Telecommunications Development Corporation, a Cayman Islands
corporation ("TDC"), owned 11,016,879 shares of GCL Common Stock, as well as
291,477 GCL Warrants. TDC was formed in 1996 for the purpose of making
investments in start-up telecommunications companies and one of the companies
in which TDC invested was Old GCL. Mr. Lee was the Chairman and Mr. Winnick was
a director of TDC. Messrs. Lee, Winnick, Brown and Porter beneficially owned a
majority of the outstanding common stock of TDC and approximately 29% of the
outstanding preferred stock of TDC. The balance of such stock was owned by
persons not affiliated with the Company (the "Unaffiliated Shareholders"). TDC
informed GCL that, in connection with the GCL Stock Offerings, it was
undergoing a reorganization to facilitate the ability of Unaffiliated
Shareholders to sell GCL Common Stock in the open market following the GCL
Stock Offerings. In connection with this reorganization, TDC proposed a
transaction (the "TDC Exchange") pursuant to which GCL acquired the 11,016,879
shares of GCL Common Stock owned by TDC in exchange for 10,866,879 newly-issued
shares of GCL Common Stock (based on a Price to Public per Share in the GCL
Stock Offerings of $19.00). The TDC Exchange was intended to enable TDC to
achieve the reorganization without the incurrence of gain for tax purposes.
Following the TDC Exchange, TDC distributed all of the shares of GCL Common
Stock and GCL Warrants owned by it to the holders of its preferred and common
stock and then liquidated (the "TDC Liquidation"). The TDC Exchange was
approved by a committee of disinterested members of the GCL's Board of
Directors. The benefit to GCL from the TDC Exchange was that it effectively
acquired 150,000 shares of GCL Common Stock for no cost. Following the TDC
Exchange and TDC Liquidation, shares of GCL Common Stock and GCL Warrants
originally held by TDC were issued to the following persons in the following
amounts:

TRANSACTIONS REGARDING CLASS A SHARES OF OLD GCL
 
  The Class A common stock of Old GCL was issued in connection with the sale by
Old GCL of the GTH Preference Shares and was offered for nominal or no
consideration as an inducement to purchase the GTH Preference Shares. The
holders of Old GCL's Class B and Class C common stock agreed to the dilutive
effects of issuing the Class A stock on the understanding that Class A stock
not ultimately needed in connection with the sale of the GTH Preference Shares
would be transferred to the holders of the Class B and Class C common stock on
a pro rata basis. Of the 31,102,950 shares of Class A common stock issued by
Old GCL, 11,250,000 shares were sold to purchasers of the GTH Preference Shares
at a price of $.67 per Class A share. The remaining 19,852,950 shares were
issued to an affiliate of CIBC Wood Gundy Securities Corporation ("CIBC
Securities"), the placement agent for the offering of the GTH Preference
Shares. This affiliate of CIBC Securities transferred 14,696,150 Class A shares
to purchasers from it of the GTH Preference Shares for no additional
consideration and retained the remaining 5,161,800 Class A shares and CIBC
Securities retained a substantial ownership interest in the GTH Preference
Shares. The holders of the Old GCL Class B and Class C shares took the position
that, consistent with their understanding regarding the disposition of Class A
shares not needed in connection with sales by CIBC Securities of the GTH
Preference Shares, the Class A shares
 
                                       81
<PAGE>
 
retained by its affiliate should be transferred to the holders of Old GCL's
Class B and Class C shares. Accordingly, such affiliate of CIBC Securities
retained 2,580,900 of the Class A shares based upon its ownership of Class C
shares and transferred the remaining 2,580,899 Class A shares as follows:

                         DESCRIPTION OF PREFERRED STOCK
 
GENERAL
 
  The Exchange Preferred Stock will be issued pursuant to and the terms are
defined by the Bye-laws. The summary contained herein of certain provisions of
the Exchange Preferred Stock to be issued by the Company in exchange for the
Old Preferred Stock in the Exchange Offer does not purport to be complete and
is qualified in its entirety by reference to the provisions of the Bye-laws,
which are filed as an exhibit to the registration statement of which this
prospectus is a part and a copy of which may be obtained upon request from the
Company. The definitions of certain terms used in the following summary are set
forth below under "--Certain Definitions." For purposes of this summary, the
term "Company" refers only to Global Crossing Holdings Ltd. and not to any of
its Subsidiaries or GCL, and references to the Preferred Stock shall be deemed
to include the Old Preferred Stock and the Exchange Preferred Stock.
 
  The shares of the Exchange Preferred Stock will be issued solely in exchange
for Old Preferred Stock pursuant to the Exchange Offer. The terms of the
Exchange Preferred Stock will be identical in all material respects to those of
the Old Preferred Stock, except that:
 
  . the shares of the Exchange Preferred Stock will have been registered
    under the Securities Act of 1933 and will be generally freely tradeable
    by holders thereof who are not a Restricted Holder, and
 
  . the registration rights and contingent interest rate provisions
    applicable to the shares of the Old Preferred Stock are generally not
    applicable to the Exchange Preferred Stock.
 
  The Company is authorized to issue and have outstanding at any time 7,500,000
shares of Preferred Stock. As of the date of this prospectus, 5,000,000 shares
of Old Preferred Stock are outstanding. Up to 2,500,000 shares will be
designated and reserved for issuance to pay dividends on the Preferred Stock if
the Company elects to pay dividends on the Preferred Stock in additional shares
of Preferred Stock prior to June 1, 2002 in accordance with the terms thereof.
All of the shares of Exchange Preferred Stock will be designated as shares of
Preferred Stock and initially will have a liquidation preference of $100.00 per
share (the "Liquidation Preference"). On December 1, 2008 (the "Mandatory
Redemption Date"), the Company will be required to redeem all outstanding
shares of Preferred Stock at a price in cash equal to the Liquidation
Preference thereof, plus all accumulated and unpaid dividends thereon to the
date of redemption. Subject to certain conditions, the Exchange Preferred Stock
will be exchangeable for the New Exchange Notes at the option of the Company on
any Dividend Payment Date. The Exchange Preferred Stock, when issued in
accordance with the terms of the Exchange Offer, will be fully paid and non-
assessable, and the Holders thereof will not have any subscription or
preemptive rights in connection therewith.
 
  The transfer agent and registrar (the "Transfer Agent") for the Preferred
Stock will be EquiServe--First Chicago Trust Division Company of New York
unless and until a successor is selected by the Company.
 
RANKING
 
  The Preferred Stock will rank junior in right of payment to all indebtedness
and other liabilities of the Company. As of September 30, 1998, after giving
pro forma effect to the offering of the Preferred Stock and the application of
the net proceeds therefrom, the Preferred Stock would have been junior in right
of payment to approximately $1,328 million of total indebtedness and other
liabilities of the Company. The Company will have the ability to issue
additional shares of Preferred Stock to pay dividends thereon, if it so elects,
on any Dividend Payment Date prior to June 1, 2002.
 
  With respect to dividends and rights upon the liquidation, winding-up and
dissolution of the Company, the Preferred Stock will rank (i) senior to each
other class of capital stock of the Company outstanding or
 
                                       83
<PAGE>
 
established after the Issue Date by the Company's Board of Directors the terms
of which do not expressly provide that it ranks senior to, or on a parity with,
the Preferred Stock as to dividends and rights upon the liquidation, winding-up
and dissolution of the Company (collectively referred to herein, together with
the common stock of the Company, as "Junior Securities"); (ii) subject to
certain conditions, on a parity with each other class of preferred stock
established after the Issue Date by the Company's Board of Directors the terms
of which expressly provide that such class or series will rank on a parity with
the Preferred Stock as to dividends and rights upon the liquidation, winding-up
and dissolution of the Company (collectively referred to herein as "Parity
Securities"); and (iii) subject to certain conditions, junior to each class of
preferred stock established after the Issue Date by the Company's Board of
Directors the terms of which expressly provide that such class or series will
rank senior to the Preferred Stock as to dividends and rights upon the
liquidation, winding-up and dissolution of the Company (collectively referred
to herein as "Senior Securities"). The Company may not authorize any new class
of Senior Securities without the approval of the Holders of at least a majority
of the then outstanding shares of Preferred Stock, voting or consenting as a
separate class. The Company may, however, authorize any new class of Parity
Securities or Junior Securities without the approval of any holder of Preferred
Stock.
 
DIVIDENDS
 
  The Holders of the Preferred Stock will be entitled to receive when, as and
if dividends are declared by the Company's Board of Directors out of funds
legally available therefor, dividends on the Preferred Stock from the Issue
Date at the rate per annum equal to 10 1/2% of the Liquidation Preference per
share of Preferred Stock, payable semi-annually in arrears on each June 1 and
December 1, or, if any such date is not a Business Day, on the next succeeding
Business Day (each, a "Dividend Payment Date"), to the Holders of record as of
the immediately preceding May 15 and November 15 (each, a "Record Date").
Dividends will be payable in cash, except that on each Dividend Payment Date
occurring prior to June 1, 2002, dividends may be paid, at the Company's
option, by the issuance of additional shares of Preferred Stock (including
fractional shares) having an aggregate Liquidation Preference per share of
Preferred Stock equal to the amount of such dividends. The issuance of such
additional shares of Preferred Stock will constitute "payment" of the related
dividend for all purposes. The first dividend payment of Preferred Stock will
be payable on June 1, 1999. Beginning on June 1, 2002 dividends on the
Preferred Stock will be payable only in cash. Dividends payable on the
Preferred Stock will be computed on the basis of a 360-day year consisting of
twelve 30-day months. For a discussion of certain United States federal income
tax considerations relevant to Holders of the Preferred Stock with respect to
the payment of dividends thereon, see "Tax Considerations--Taxation of Holders
of Preferred Stock and Exchange Notes--United States Federal Income Tax
Considerations."
 
  Dividends on the Preferred Stock will accrue whether or not the Company has
earnings or profits, whether or not there are funds legally available for the
payment of such dividends and whether or not dividends are declared. Dividends
will accumulate to the extent they are not paid on the Dividend Payment Date
for the period to which they relate. In the event that dividends on the
Preferred Stock are in arrears and unpaid for three or more semi-annual
Dividend Periods (whether or not consecutive), Holders of the Preferred Stock
will be entitled to certain voting rights. See "--Voting Rights; Amendment."
The terms of the Preferred Stock will provide that the Company will take all
actions required or permitted under Bermuda law to permit the payment of
dividends on the Preferred Stock, including, without limitation, through the
revaluation of its assets in accordance with Bermuda law, and to make or keep
funds legally available for the payment of dividends. Dividends on account of
arrears for any past Dividend Period and dividends in connection with any
optional redemption may be declared and paid at any time, without reference to
any regular Dividend Payment Date, to Holders of record of Preferred Stock on
such date, not more than 45 days prior to the payment thereof, as may be fixed
by the Company's Board of Directors.
 
  No dividend whatsoever shall be declared or paid upon, or any sum set apart
for the payment of dividends upon, any outstanding share of Preferred Stock
with respect to any Dividend Period unless all dividends for all preceding
Dividend Periods have been declared and paid, or declared and a sufficient sum
set apart for the payment of such dividend, upon all outstanding shares of
Preferred Stock. No full dividends may be declared or
 
                                       84
<PAGE>
 
paid or funds set apart for the payment of dividends on any Parity Securities
for any period unless full cumulative dividends shall have been or
contemporaneously are declared and paid (or are deemed declared and paid) in
full or declared and, if payable in cash, a sum in cash sufficient for such
payment set apart for such payment on the Preferred Stock. If full dividends
are not so paid, the Preferred Stock will share dividends pro rata with the
Parity Securities. So long as any Preferred Stock is outstanding and unless and
until full cumulative dividends have been paid (or are deemed paid) in full on
the Preferred Stock: (i) no dividend shall be declared or paid upon, or any sum
set apart for the payment of dividends upon, any shares of Junior Securities;
(ii) no other distribution shall be declared or made upon, or any sum set apart
for the payment of any distribution upon, any shares of Junior Securities;
(iii) no shares of Parity Securities or Junior Securities shall be purchased,
redeemed or otherwise acquired or retired for value; (iv) no warrants, rights,
calls or options to purchase any Parity Securities or Junior Securities shall
be directly or indirectly issued; and (v) no monies shall be paid into or set
apart or made available for a sinking or other like fund for the purchase,
redemption or other acquisition or retirement for value of any shares of Parity
Securities or Junior Securities.
 
The Senior Notes Indenture contains, and future credit agreements or other
agreements relating to Indebtedness to which the Company becomes a party may
contain, prohibitions or restrictions on the ability of the Company to pay cash
dividends on the Preferred Stock. See "Risk Factors--Covenant Restrictions" and
"Description of Certain Indebtedness--9 5/8% Senior Notes." All references
herein to dividends shall be deemed to include any special dividends which may
become payable on the Preferred Stock.
 
LIQUIDATION PREFERENCE
 
  Upon any voluntary or involuntary liquidation, dissolution or winding-up of
the Company or a reduction or decrease in its capital stock resulting in a
distribution of assets to the holders of any class or series of the Company's
capital stock, each Holder of the Preferred Stock will be entitled to payment
out of the assets of the Company available for distribution of an amount equal
to the then effective Liquidation Preference per share of Preferred Stock held
by such Holder, plus all accumulated and unpaid dividends thereon to the date
fixed for such liquidation, dissolution, winding-up or reduction or decrease in
capital stock, before any distribution is made on any Junior Securities,
including, without limitation, common stock of the Company. After payment in
full of the then effective Liquidation Preference and all accumulated and
unpaid dividends thereon to which Holders of Preferred Stock are entitled, such
Holders will not be entitled to any further participation in any distribution
of assets of the Company. If, upon any voluntary or involuntary liquidation,
dissolution or winding-up of the Company or a reduction or decrease in its
capital stock, the amounts payable with respect to the Preferred Stock and all
other Parity Securities are not paid in full, the Holders of the Preferred
Stock and the Parity Securities will share equally and ratably in any
distribution of assets of the Company in proportion to the full liquidation
preference and all accumulated and unpaid dividends to which each such Holder
is entitled. However, neither the voluntary sale, conveyance, exchange or
transfer (for cash, shares of stock, securities or other consideration) of all
or substantially all of the property or assets of the Company nor the
consolidation or merger of the Company with or into one or more corporations
will be deemed to be a voluntary or involuntary liquidation, dissolution or
winding-up of the Company or a reduction or decrease in its capital stock.
 
  The Bye-laws do not contain any provision requiring funds to be set aside to
protect the Liquidation Preference of the Preferred Stock, although such
Liquidation Preference will be substantially in excess of the par value of the
shares of the Preferred Stock and there can be no assurance that, upon any such
voluntary or involuntary liquidation, dissolution or winding-up of the Company
or a reduction or decrease in its capital stock that there will be funds
available in an amount sufficient to pay such Liquidation Preference in full,
in part or at all.
 
EXCHANGE
 
  The Company may, at its option, on any Dividend Payment Date, exchange, in
whole, but not in part, all then outstanding shares of Preferred Stock for
Exchange Notes with a principal amount equal to the then effective Liquidation
Preference of the Preferred Stock; provided that (i) on the date of such
exchange there are
 
                                       85
<PAGE>
 
no accumulated and unpaid dividends on the Preferred Stock (including the
dividend payable on such date) or other contractual impediments to such
exchange; and (ii) immediately after giving effect to such exchange, no Default
or Event of Default under the Indenture or the Senior Notes Indenture (in each
case as defined therein) would exist or be caused thereby. The exchange of the
Preferred Stock into Exchange Notes would be restricted by the current terms of
the Senior Notes Indenture, including with respect to the incurrence of
Indebtedness. See "Description of Certain Indebtedness--9 5/8% Senior Notes."
 
  Upon any exchange pursuant to the preceding paragraph, Holders of Preferred
Stock will be entitled to receive $1.00 principal amount of Exchange Notes for
each $1.00 of the then effective Liquidation Preference per share of Exchange
Preferred Stock held by such Holders. The Exchange Notes will be issued in
registered form, without coupons and will be issued in principal amounts of
$1,000 and integral multiples thereof (to the extent possible) so that the
Holders of Preferred Stock will receive certificates representing the entire
amount of Exchange Notes to which the Holders of Preferred Stock are entitled;
provided that the Company may pay cash in lieu of issuing Exchange Notes having
a principal amount less than $1,000.
 
  Notice of the intention to exchange the Preferred Stock into Exchange Notes
will be sent by or on behalf of the Company not more than 60 nor less than 30
days prior to the date of exchange (the "Exchange Date"), by first class mail,
postage prepaid, to each Holder of record of Preferred Stock at its registered
address. In addition to any information required by law or by the applicable
rules of any exchange upon which the Preferred Stock may then be listed or
admitted to trading, such notice will state: (i) the Exchange Date; (ii) the
place or places where certificates for such shares are to be surrendered for
exchange, including any procedures applicable to exchanges to be accomplished
through book-entry transfers; and (iii) that dividends on the Preferred Stock
to be exchanged will cease to accumulate on the Exchange Date. If notice of any
exchange has been properly given, and if on or before the Exchange Date the
Exchange Notes have been duly executed and authenticated and deposited with the
Transfer Agent, then on and after the close of business on the Exchange Date,
the Preferred Stock to be exchanged will no longer be deemed to be outstanding
and may thereafter be issued in the same manner as the other authorized but
unissued preferred stock of the Company, but not as Preferred Stock, and all
rights of the Holders thereof as shareholders of the Company will cease, except
the right of such Holders to receive upon surrender of their certificates the
Exchange Notes and all accrued and unpaid interest thereon.
 
REDEMPTION
 
 Mandatory Redemption
 
  On the Mandatory Redemption Date, the Company will be required to redeem all
outstanding shares of Preferred Stock at a price in cash equal to the then
effective Liquidation Preference thereof, plus all accumulated and unpaid
dividends thereon to the date of redemption. The Company will not be required
to make sinking fund payments with respect to the Preferred Stock. The Bye-laws
will provide that the Company will take all actions required or permitted under
Bermuda law to permit such redemption.
 
 Optional Redemption
 
  Except as set forth below and under "--Optional Tax Redemption," the
Preferred Stock will not be redeemable at the Company's option prior to
December 1, 2003. Thereafter, the Preferred Stock will be subject to redemption
at any time at the option of the Company, in whole or in part, upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of the then effective Liquidation Preference) set forth below, plus
all accumulated and unpaid dividends thereon to the applicable redemption date,
if redeemed during the twelve-month period beginning on December 1 of the years
indicated below:

  Notwithstanding the foregoing, at any time prior to December 1, 2001, the
Company may, on any one or more occasions, redeem up to 35% of the then
effective aggregate Liquidation Preference of the Preferred Stock then
outstanding at a redemption price equal to 110.500% of the then effective
Liquidation Preference thereof, plus all accumulated and unpaid dividends
thereon to the redemption date, with the net cash proceeds received from one or
more equity offerings made by the Company or GCL (to the extent such net cash
proceeds received by GCL were contributed to the Company as common equity
capital); provided that at least 65% of the then effective aggregate
Liquidation Preference of Preferred Stock then outstanding remains outstanding
immediately after the occurrence of any such redemption. The Company may make
any such redemption upon not less than 30 nor more than 60 days' notice (but in
no event more than 90 days after the closing of the related Equity Offering).
Any such notice may be given prior to the completion of the related Equity
Offering and any such redemption may, at the Company's discretion, be subject
to the satisfaction of one or more conditions precedent, including, but not
limited to, the completion of the related equity offering.
 
  In addition, at any time prior to December 1, 2003, the Preferred Stock may
also be redeemed at the option of the Company, in whole but not in part, upon
the occurrence of a Change of Control, upon not less than 30 nor more than 60
days' prior notice (but in no event may any such redemption occur more than 90
days after the occurrence of such Change of Control) mailed by first-class mail
to each Holder's registered address, at a redemption price equal to 100% of the
then effective Liquidation Preference thereof, plus the Applicable Premium as
of, and all accumulated and unpaid dividends thereon to, the date of redemption
(the "Redemption Date").
 
  "Applicable Premium" means, with respect to any share of Preferred Stock on
any Redemption Date, the greater of (i) 1.0% of the then effective Liquidation
Preference of such share of Preferred Stock or (ii) the excess of (a) the
present value at such Redemption Date of (1) dividends on the Preferred Stock
accumulating until and including December 1, 2003 (assuming payment thereof in
cash on the applicable Dividend Payment Dates) and (2) the Liquidation
Preference and any applicable optional redemption premium therefor payable on
such Redemption Date for such share (assuming payment thereof on December 1,
2003), computed using a discount rate equal to the Treasury Rate plus 50 basis
points over (b) the then effective Liquidation Preference of such share of
Preferred Stock, if greater.
 
  "Treasury Rate" means, as of any Redemption Date, the yield to maturity as of
such Redemption Date of United States Treasury securities with a constant
maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two
Business Days prior to the Redemption Date (or, if such Statistical Release is
no longer published, any publicly available source of similar market data))
most nearly equal to the period from the Redemption Date to December 1, 2003;
provided, however, that if the period from the Redemption Date to December 1,
2003 is less than one year, the weekly average yield on actually traded United
States Treasury securities adjusted to a constant maturity of one year shall be
used.
 
 Optional Tax Redemption
 
  The Preferred Stock will be subject to redemption at the option of the
Company or a successor corporation at any time, in whole but not in part, upon
not less than 30 nor more than 60 days' notice, at a redemption price equal to
the then effective Liquidation Preference thereof, plus all accumulated and
unpaid dividends thereon to the redemption date if, as a result of any change
in or amendment to the laws or any regulations or ruling promulgated thereunder
of (x) Bermuda or any political subdivision or governmental authority thereof
or therein having the power to tax, (y) any jurisdiction, other than the United
States, from or through which payment on the Preferred Stock is made by the
Company or a successor corporation, or its paying agent in its capacity as such
or any political subdivision or governmental authority thereof or therein
having the power to tax or (z) any other jurisdiction, other than the United
States, in which the Company or a successor corporation is organized, or any
political subdivision or governmental authority thereof or therein having the
power to tax, or any change in the official application or interpretation of
such laws, regulations or rulings, or any change in the official application or
interpretation of, or any execution of or amendment to, any treaty or treaties
affecting
 
                                       87
<PAGE>
 
taxation to which such jurisdiction (or such political subdivision or taxing
authority) is a party (a "Change in Tax Law"), which becomes effective on or
after the date hereof, the Company or a successor corporation is or would be
required on the next succeeding dividend payment date to pay Additional Amounts
with respect to the Preferred Stock (as described under "--Payment of
Additional Amounts"), and the payment of such Additional Amounts cannot be
avoided by the use of any reasonable measures available to the Company or a
successor corporation.
 
  In addition, the Preferred Stock will be subject to redemption at the option
of the Company at any time, in whole but not in part, upon not less than 30 nor
more than 60 days' notice, at a redemption price equal to the then effective
Liquidation Preference thereof, plus all accumulated and unpaid dividends
thereon to the redemption date, if the Person formed by a consolidation or
amalgamation of the Company or into which the Company is merged or to which the
Company conveys, transfers or leases its properties and assets substantially as
an entirety is required, as a consequence of such consolidation, amalgamation,
merger, conveyance, transfer or lease and as a consequence of a Change in Tax
Law occurring after the date of such consolidation, amalgamation, merger,
conveyance, transfer or lease, to pay Additional Amounts in respect of any tax,
assessment or governmental charge imposed on any Holder of Preferred Stock.
 
 Payment of Additional Amounts
 
  If any deduction or withholding for any present or future taxes, assessments
or other governmental charges of (x) Bermuda or any political subdivision or
governmental authority thereof or therein having power to tax, (y) any
jurisdiction, other than the United States, from or through which payment on
the Preferred Stock is made by the Company or a successor corporation, or its
paying agent in its capacity as such or any political subdivision or
governmental authority thereof or therein having the power to tax or (z) any
other jurisdiction, other than the United States, in which the Company or a
successor corporation is organized, or any political subdivision or
governmental authority thereof or therein having the power to tax shall at any
time be required by such jurisdiction (or any such political subdivision or
taxing authority) in respect of any amounts to be paid by the Company or a
successor corporation with respect to the Preferred Stock, the Company or a
successor corporation will pay to each Holder of Preferred Stock as additional
dividends, such additional amounts ("Additional Amounts") as may be necessary
in order that the net amounts paid to such holder of such Preferred Stock who,
with respect to any such tax, assessment or other governmental charge, is not
resident in, or a citizen of, such jurisdiction, after such deduction or
withholding, shall be not less than the amount specified in such Preferred
Stock to which such Holder is entitled; provided, however, that the Company or
a successor corporation shall not be required to make any payment 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 (or between a fiduciary, settlor,
       beneficiary, member or shareholder of, or possessor of a power over,
       such Holder, if such Holder is an estate, trust, partnership, limited
       liability company or corporation) and the taxing jurisdiction or any
       political subdivision or territory or possession thereof or area subject
       to its jurisdiction, including, without limitation, such Holder (or such
       fiduciary, settlor, beneficiary, member, shareholder 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 a permanent establishment therein, (b) the presentation of Preferred
       Stock (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, or (c) the presentation of Preferred Stock for payment in
       Bermuda or any political subdivision thereof or therein, unless such
       Preferred Stock could not have been presented for payment elsewhere;
 
  (ii) 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 payable
         otherwise than by withholding from payment of the Liquidation
         Preference of or any dividends on the Preferred Stock;
 
                                       88
<PAGE>
 
  (iv) 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 Preferred Stock to comply with a request of the Company addressed
       to the Holder (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; or
 
  (v)  Any combination of items (i), (ii), (iii) and (iv) above;
 
nor shall Additional Amounts be paid with respect to any payment of the
Liquidation Preference of or dividends on any Preferred Stock to any Holder who
is a fiduciary or partnership or limited liability company or other than the
sole beneficial owner of such payment to the extent such payment would be
required by the laws of (x) Bermuda or any political subdivision or
governmental authority thereof or therein having the power to tax, (y) any
jurisdiction, other than the United States, from or through which payment on
the Preferred Stock is made by the Company or a successor corporation, or its
paying agent in its capacity as such or any political subdivision or
governmental authority thereof or therein having the power to tax or (z) any
other jurisdiction, other than the United States, in which the Company or a
successor corporation is organized, or any political subdivision or
governmental authority thereof or therein having the power to tax to be
included in the income for tax purposes of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership, limited liability
company or beneficial owner who would not have been entitled to such Additional
Amounts had it been the Holder of such Preferred Stock.
 
  The Company shall provide the Transfer Agent with the official acknowledgment
of the relevant taxing authority (or, if such acknowledgment is not available,
a certified copy thereof) evidencing the payment of the withholding taxes, if
any, by the Company. Copies of such documentation shall be made available to
the Holders of the Preferred Stock or the Transfer Agent, as applicable, upon
request therefor.
 
  All references herein to dividends on the Preferred Stock shall include any
Additional Amounts payable by the Company in respect of such Preferred Stock.
 
VOTING RIGHTS; AMENDMENT
 
  Holders of record of the Preferred Stock will have no voting rights, except
as required by law and as provided in the Bye-laws. The Bye-laws, however, will
provide that upon: (i) the accumulation of unpaid dividends (and, if beginning
on June 1, 2002, such dividends are not paid in cash) on the outstanding
Preferred Stock in an amount equal to three semi-annual dividend payments
(whether or not consecutive); (ii) failure by the Company to satisfy any
repurchase obligation (including, without limitation, pursuant to any required
Change of Control Offer) or mandatory redemption obligation with respect to the
Preferred Stock; (iii) failure by the Company to comply with the provisions
described below under the caption "--Repurchase at the Option of Holders--
Change of Control"; (iv) failure by the Company for 60 days after notice to
comply with any of its other agreements applicable to the Preferred Stock set
forth in the Bye-laws; or (v) 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 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, which default 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 the maturity of which has been
so accelerated, aggregates $25.0 million or more (each of the events described
in the immediately preceding clauses (i)-(v) being referred to herein as a
"Voting Rights Triggering Event"); then the Holders of a majority of the then
outstanding shares of Preferred Stock, voting as a separate single class, will
be entitled to elect two
 
                                       89
<PAGE>
 
members to the Company's Board of Directors and the number of members of the
Company's Board of Directors will immediately and automatically be increased by
two. Voting rights arising as a result of a Voting Rights Triggering Event will
continue until such time as all dividends in arrears on the Preferred Stock
have been paid in full and all other Voting Rights Triggering Events have been
cured or waived by the Holders of at least a majority of the then outstanding
shares of Preferred Stock, at which time the term of office of any such members
of the Company's Board of Directors so elected shall terminate and such
directors shall be deemed to have resigned.
 
  In addition to the provisions described above under the caption "--Ranking,"
the Bye-laws also will provide that the Company will not, without the approval
of the Holders of at least two-thirds of the then outstanding shares of
Preferred Stock, amend, alter or repeal any of the provisions of the Company's
Bye-laws so as to adversely affect the powers, preferences or rights of the
Holders of the Preferred Stock, or reduce the time for any notice to which the
Holders of the Preferred Stock may be entitled. Subject to the provisions
described above under "--Ranking," the Bye-laws will provide that an amendment
thereof solely to authorize or create, or to increase the amount of Junior
Securities, Parity Securities or Senior Securities, shall not be deemed to
adversely affect the powers, preferences or rights of the Holders of the
Preferred Stock.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
 Change of Control
 
  Upon the occurrence of a Change of Control, each Holder of Preferred Stock
will have the right to require the Company to purchase all or any part of such
Holder's Preferred Stock pursuant to the offer described below (the "Change of
Control Offer") at a purchase price in cash (the "Change of Control Payment")
equal to 101% of the then effective Liquidation Preference thereof, plus all
accumulated and unpaid dividends thereon to the date of purchase (subject to
the right of Holders of record on the relevant record date to receive dividends
due on the relevant Dividend Payment Date); provided, however, that the Company
shall not be obligated to repurchase Preferred Stock pursuant to this covenant
in the event that it has exercised its rights to redeem all of the Preferred
Stock as described above under "--Optional Redemption." Within 30 days
following any Change of Control, the Company will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of
Control and offering to purchase such Holder's Preferred Stock on the date
specified in such notice, which date shall be no earlier than 30 and no later
than 60 days from the date such notice is mailed (the "Change of Control
Payment Date"), in accordance with the procedures required by the Bye-laws 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 to the extent such
laws and regulations are applicable in connection with the purchase of
Preferred Stock as a result of a Change of Control. To the extent that the
provisions of any securities laws or regulations conflict with any of the
provisions of this covenant, the Company will comply with the applicable
securities laws and regulations and will be deemed not to have breached its
obligations under this covenant by virtue thereof.
 
  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Preferred Stock properly tendered pursuant
to the Change of Control Offer, (2) deposit with the Transfer Agent an amount
equal to the Change of Control Payment in respect of the Preferred Stock so
tendered and (3) deliver or cause to be delivered to the Transfer Agent
Preferred Stock so accepted together with an Officers' Certificate stating the
aggregate Liquidation Preference of Preferred Stock being purchased by the
Company. The Transfer Agent will promptly mail or deliver to each Holder of
Preferred Stock so tendered the Change of Control Payment for such Preferred
Stock, and the Transfer Agent will promptly countersign and mail or deliver (or
cause to be transferred by book-entry) to each Holder new Preferred Stock equal
in Liquidation Preference to any unpurchased portion of Preferred Stock
surrendered, if any. 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.
 
                                       90
<PAGE>
 
  The Company will not be required to make a Change of Control Offer upon the
occurrence of 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 Bye-laws applicable to a Change of Control Offer
made by the Company, and purchases all Preferred Stock validly tendered and not
withdrawn under such Change of Control Offer.
 
 Asset Sales
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, consummate any Asset Sale, unless (i) the Company
(or such Restricted Subsidiary, as the case may be) receives consideration at
the time of such Asset Sale at least equal to the fair market value (as
determined in good faith by the Board of Directors (including as to the value
of all noncash consideration) and set forth in an Officer's Certificate
delivered to the Transfer Agent) of the assets or Equity Interests issued or
sold or otherwise disposed of and (ii) at least 75% of the consideration
therefor is in the form of cash and/or Cash Equivalents, and (iii) the Net
Proceeds received by the Company (or such Restricted Subsidiary, as the case
may be) from such Asset Sale are applied within 360 days following the receipt
of such Net Proceeds (a) first, to the extent the Company (or such Restricted
Subsidiary, as the case may be) elects, to the redemption or repurchase of
outstanding Indebtedness and (b) to the extent of the balance of such Net
Proceeds after application as described in (a) above and to the extent the
Company (or such Restricted Subsidiary, as the case may be) elects, to
reinvest, or enter into a legally binding agreement to reinvest, such Net
Proceeds (or any portion thereof) in assets that are used or useful in a
Permitted Business. The balance of such Net Proceeds, after the application of
such Net Proceeds as described in the immediately preceding clauses (a) and
(b), shall constitute "Excess Proceeds."
 
  When the aggregate amount of Excess Proceeds equals or exceeds $15.0 million
(taking into account income earned on such Excess Proceeds), the Company will
be required to make an offer to all Holders of Preferred Stock (an "Asset Sale
Offer") to purchase the maximum Liquidation Preference of Preferred Stock that
may be purchased out of the Excess Proceeds, at a purchase price in cash in an
amount equal to 100% of the effective Liquidation Preference thereof, plus all
accumulated and unpaid dividends thereon to the date of purchase, in accordance
with the procedures set forth in the Bye-laws. To the extent that any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Company may use
such Excess Proceeds at its discretion. If the aggregate Liquidation Preference
of Preferred Stock tendered into such Asset Sale Offer surrendered by Holders
thereof exceeds the amount of Excess Proceeds, the Transfer Agent shall select
the Preferred Stock to be purchased on a pro rata basis. Upon completion of
such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero for
purposes of the first sentence of this paragraph.
 
  The amount of (x) any liabilities (as shown on the Company's (or such
Restricted Subsidiary's, as the case may be) most recent balance sheet) of the
Company or any Restricted Subsidiary (other than contingent liabilities) that
are assumed by the transferee of any such assets pursuant to an agreement that
releases the Company or any Restricted Subsidiary from all liability in respect
thereof, (y) Indebtedness of any Restricted Subsidiary that is no longer a
Restricted Subsidiary as a result of such Asset Sale, to the extent that the
Company and each other Restricted Subsidiary are released from any guarantee of
payment of the principal amount of such Indebtedness in connection with such
Asset Sale and (z) any securities, notes or other obligations received by the
Company (or such Restricted Subsidiary, as the case may be) from such
transferee that are contemporaneously (subject to ordinary settlement periods)
converted by the Company (or such Restricted Subsidiary, as the case may be)
into cash and/or Cash Equivalents (to the extent of the cash and/or Cash
Equivalents received), will be deemed to be cash and/or Cash Equivalents for
purposes of this provision.
 
CERTAIN COVENANTS
 
 Restricted Payments
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly: (i) declare or pay any dividend or make any other
payment or distribution on account of the Company's or any
 
                                       91
<PAGE>
 
of its Restricted Subsidiaries' Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation
involving the Company or any of its Restricted Subsidiaries) or to the direct
or indirect holders of the Company's or any of its Restricted Subsidiaries'
Equity Interests (other than dividends or distributions payable in Equity
Interests (other than Disqualified Stock) of the Company or to the Company or
a Restricted Subsidiary of the Company); (ii) purchase, redeem or otherwise
acquire or retire for value (including, without limitation, in connection with
any merger or consolidation involving the Company) any Equity Interests of the
Company or any direct or indirect parent of the Company (other than any such
Equity Interests owned by the Company or any Wholly Owned Restricted
Subsidiary of the Company); (iii) make any payment on or with respect to, or
purchase, redeem, defease or otherwise acquire or retire for value any Junior
Securities (other than dividends or distributions payable in Junior Securities
(other than Disqualified Stock) of the Company or to the Company or a
Restricted Subsidiary of the Company); or (iv) make any Restricted Investment
(all such payments and other actions set forth in clauses (i) through (iv)
above being collectively referred to as "Restricted Payments"), unless:
 
  (a) at the time of and after giving effect to such Restricted Payment, no
      Voting Rights Triggering Event shall have occurred and be continuing or
      would occur as a consequence thereof;
 
  (b) in the case of clauses (i), (ii) and (iii) above, and, in the case of
      any Restricted Investment that is not an Investment in a Permitted
      Business, the Company would, at the time of such Restricted Payment
      and after giving pro forma effect thereto as if such Restricted Payment
      had been made at the beginning of the applicable four-quarter period,
      have been permitted to incur at least $1.00 of additional Indebtedness
      pursuant to either clause (i) or (ii) of the first paragraph of the
      covenant described below under the caption "--Incurrence of Indebtedness
      and Issuance of Preferred Stock;" and
 
  (c) such Restricted Payment, together with the aggregate amount of all other
      Restricted Payments made by the Company and its Restricted Subsidiaries
      and any Permitted Investments made pursuant to clause (h) of the
      definition of Permitted Investments after the date hereof (excluding
      Restricted Payments permitted by clauses (iii), (iv), (v), (vii), (viii)
      and (ix) (but, in the case of clause (ix), only to the extent that such
      Restricted Payments are reflected as an expense on the income statement
      of GCL) of the next succeeding paragraph), is less than the sum, without
      duplication, of (i) the remainder of (x) 100% of the cumulative
      Consolidated Cash Flow (or, in the case Consolidated Cash Flow shall be
      negative, less 100% of such deficit) from the Issue Date through the
      last day of the last full fiscal quarter immediately preceding such
      Restricted Payment minus (y) the product of 1.5 times the cumulative
      Consolidated Interest Expense from the Issue Date through the last day
      of the last full fiscal quarter immediately preceding such Restricted
      Payment, plus (ii) 100% of the aggregate net cash proceeds and the fair
      market value (as determined in good faith by the Board of Directors) of
      property or assets 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
      including the Preferred Stock) or from the issue or sale of Disqualified
      Stock or debt securities of the Company that have been converted into
      such Equity Interests (other than Equity Interests (or Disqualified
      Stock or convertible debt securities) sold to a Subsidiary of the
      Company), plus the amount of cash or the fair market value (as
      determined above) of property or assets received by the Company or any
      Restricted Subsidiary upon such conversion or exchange, plus (iii) the
      aggregate amount equal to the net reduction in Investments in
      Unrestricted Subsidiaries resulting from (x) dividends, distributions,
      interest payments, return of capital, repayments of Investments or other
      transfers of assets to the Company or any Restricted Subsidiary from any
      Unrestricted Subsidiary, (y) proceeds realized by the Company or any
      Restricted Subsidiary upon the sale of such Investment to a Person other
      than GCL, the Company or any Subsidiary of the Company, or (z) the
      redesignation of any Unrestricted Subsidiary as a Restricted Subsidiary,
      not to exceed in the case of any of the immediately preceding clauses
      (x), (y) or (z) the aggregate amount of Restricted Investments made by
      the Company or any Restricted Subsidiary in such Unrestricted Subsidiary
      after the Issue Date, plus (iv) to the extent that any Restricted
      Investment that was made after the Issue Date is sold for cash or
      otherwise liquidated or repaid for cash, the amount of proceeds (net of
      any cost of disposition) equal to the initial amount of such Restricted
      Investment.

preceding paragraph) plus 50% of the net gain realized and not otherwise
included in Consolidated Cash Flow from the sale of Restricted Investments;
(ix) the payment of any dividend or the making of any distribution to GCL by
the Company or any Restricted Subsidiary to pay or permit GCL to pay any GCL
Expenses or any Related Taxes; and (x) other Restricted Payments in an
aggregate amount not to exceed $25.0 million.
 
  The Board of Directors may not designate any Subsidiary of the Company (other
than a newly created Subsidiary in which no Investment has previously been made
(other than the amount required to capitalize such Subsidiary in connection
with its organization)) as an Unrestricted Subsidiary (a "Designation") unless:
(i) no Voting Rights Triggering Event shall have occurred and be continuing at
the time of or after giving effect to such Designation; (ii) the Company would,
immediately after giving effect to such Designation, have been permitted to
incur at least $1.00 of additional Indebtedness pursuant to either clause (i)
or (ii) of the first paragraph of the covenant described below under "--
Incurrence of Indebtedness and Issuance of Preferred Stock" and (iii) the
Company would not be prohibited under the terms of the Preferred Stock from
making an Investment at the time of such Designation (assuming the
effectiveness of such Designation for purposes of clauses (a) and (b) of the
first paragraph of this covenant) in an amount equal to the fair market value
of the net Investment of the Company or any other Restricted Subsidiary in such
Subsidiary on such date.
 
  In the event of any such Designation, 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
will reduce the amount available for Restricted Payments under the first
paragraph of this covenant or Permitted Investments, as applicable. All such
outstanding Investments will be deemed to constitute Restricted Payments in an
amount equal to the fair market value of such Investments at the time of such
Designation.
 
  The terms of the Preferred Stock will further provide that a Designation may
be revoked (a "Revocation") by a resolution of the Board of Directors delivered
to the Transfer Agent, provided that the Company will not make any Revocation
unless: (i) no Voting Rights Triggering Event shall have occurred and be
continuing at the time of or after giving effect to such Designation and (ii)
all Indebtedness of such Unrestricted Subsidiary outstanding immediately
following such Revocation would, if incurred at such time, have been permitted
to be incurred at such time for all purposes under the covenant described below
under "--Incurrence of Indebtedness and Issuance of Preferred Stock."
 
 
                                       93
<PAGE>
 
  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 asset(s) or securities that are required to be
valued by this covenant shall be determined in good faith by the Board of
Directors (such determination to be based upon an opinion or appraisal issued
by an accounting, appraisal or investment banking firm of national standing if
such fair market value exceeds $15.0 million).
 
 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, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "incur") any Indebtedness (including Acquired Debt)
and the Company will not issue any Disqualified Stock and will not permit any
of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock and its Restricted Subsidiaries may
incur Indebtedness or issue Disqualified Stock or preferred stock if either:
 
  (i)  the Consolidated Leverage Ratio is less than 5.5 to 1.0 (prior to
       December 1, 2001) or 5.0 to 1.0 (subsequent to December 1, 2001); or
 
  (ii) the Consolidated Capital Ratio is less than 2.5 to 1.0.
 
  Notwithstanding the foregoing, the provisions of the paragraph set forth
above will not apply to the incurrence of any of the following items of

  (a)  The incurrence by the Company or any of its Restricted Subsidiaries of
       Existing Indebtedness;
 
  (b)  The incurrence of Indebtedness by the Company to any Restricted
       Subsidiary or Indebtedness of any Restricted Subsidiary to the Company
       or any other Restricted Subsidiary (but only for so long as such
       Indebtedness is held by the Company or such Restricted Subsidiary);
 
  (c)  The issuance by the Company of preferred stock to any other Restricted
       Subsidiary or the issuance by any Restricted Subsidiary of preferred
       stock to the Company or any other Restricted Subsidiary (but only for so
       long as such preferred stock is held by the Company or such Restricted
       Subsidiary);
 
  (d)  The incurrence by the Company or any of its Restricted Subsidiaries of
       Indebtedness pursuant to acquisitions of capacity made in the ordinary

       Hedging Obligations that are incurred for the purpose of fixing or
       hedging interest or foreign currency exchange rate risk with respect to
       any floating rate Indebtedness that is permitted to be outstanding;
 
  (f)  The incurrence by the Company or any of its Restricted Subsidiaries of
       Indebtedness of a Restricted Subsidiary incurred and outstanding on the
       date on which such Restricted Subsidiary was acquired by the Company;
       provided, however, that at the time such Restricted Subsidiary is
       acquired by the Company (giving effect to such acquisition), the Company
       would have been able to incur $1.00 of additional Indebtedness pursuant
       to the immediately preceding paragraph;
 
  (g)  The incurrence by the Company or any of its Restricted Subsidiaries of
       Permitted Refinancing Indebtedness in exchange for, or the net proceeds

       than intercompany Indebtedness) that was permitted to be incurred
       pursuant to the immediately preceding paragraph hereof or clauses (a),
       (f), (g), (h), (j), (m) or (n) of this paragraph;
 
  (h)  The incurrence by the Company or any of its Restricted Subsidiaries of
       additional Indebtedness not otherwise permitted to be incurred pursuant
       to this paragraph in an aggregate principal amount (or accreted value,
       as applicable) at any time outstanding, including all Permitted
       Refinancing Indebtedness incurred to refund, refinance or replace any
       Indebtedness incurred pursuant to this clause (h), not to exceed $50.0
       million;
 
                                       94

       in accordance with the covenant described above under "--Repurchase at
       the Option of Holders--Asset Sales."
 
  (j)  The incurrence by the Company or any Restricted Subsidiary of Purchase
       Money Indebtedness, provided that the amount of such Purchase Money
       Indebtedness does not exceed 100% of the cost of construction,
       installation, acquisition, lease, development, design, engineering,

  (n)  The guarantee by the Company or any Restricted Subsidiary of
       Indebtedness of the Company or any Restricted Subsidiary of the Company

 Merger, Consolidation, or Sale of Assets
 
  Without the affirmative vote of the holders of a majority of the then
outstanding shares of Preferred Stock, voting or consenting as a separate
class, the Company may not, directly or indirectly, consolidate or merge with
or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, convey or otherwise dispose of all or substantially all of
its properties or assets, in one or more related transactions, to another
Person unless: (i) the Company is the surviving corporation or the Person
formed by or surviving any such consolidation or merger (if other than the
Company) or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made is a corporation organized or existing under
the laws of the United States, any state thereof or the District of Columbia,
or Bermuda; (ii) the Preferred Stock shall be converted into or exchanged for

Preferred Stock had immediately prior to such transactions; (iii) immediately
after such transaction, except in the case of a merger of the Company with or
into a Wholly Owned Restricted Subsidiary of the Company, the Company or the
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made (A) will have Consolidated Net Worth
immediately after the transaction equal to or greater than the Consolidated Net
Worth of the Company immediately preceding the transaction and (B) will,
immediately after such transaction and after giving pro forma effect thereto
and any related financing transactions as if the same had occurred at the
beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to either clause (i) or (ii) of the
first paragraph of the covenant described above under "--Incurrence of
Indebtedness and Issuance of Preferred Stock." The terms of the Preferred Stock
will also provide that 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.
 
 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 or assets to, or purchase any property or assets from, or
enter into or make or amend any transaction, contract, agreement,
understanding, loan, advance or
 
                                       95
<PAGE>
 
guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an
"Affiliate Transaction"), unless (i) such Affiliate Transaction is on terms
that are not materially 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 an unrelated
Person and (ii) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $25.0
million, the Company delivers to the Transfer Agent a resolution of the Board
of Directors set forth in an Officers' Certificate certifying that such
Affiliate Transaction complies with clause (i) above and that such Affiliate
Transaction is approved by a majority of the disinterested members of the Board
of Directors and an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view is obtained from an accounting,
appraisal or investment banking firm of national standing. Notwithstanding the
foregoing, the following items shall not be deemed to be Affiliate
Transactions: (i) (a) the entering into, maintaining or performance of any
employment contract, collective bargaining agreement, benefit plan, program or

or the relevant Restricted Subsidiary than the terms of such agreement prior to
such amendment), (vi) transactions with respect to capacity or dark fiber
between the Company or any Restricted Subsidiary and any Unrestricted
Subsidiary or other Affiliate and joint sales and marketing pursuant to an
agreement or agreements between the Company or any Restricted Subsidiary and
any Unrestricted Subsidiary or other Affiliate (provided that in the case of
this clause (vi), such agreements are on terms that are no less favorable to
the Company or the relevant Restricted Subsidiary than those that could have
been obtained at the time of such transaction in an arm's-length transaction
with an unrelated third party or, in the case of a transaction with an
Unrestricted Subsidiary, are either (x) entered into in connection with a
transaction involving the selection by a customer of cable system capacity
entered into in the ordinary course of business or (y) involve the provision by
the Company or a Restricted Subsidiary to an Unrestricted Subsidiary of sales
and marketing services, operations, administration and maintenance services or
development services for which the Company or such Restricted Subsidiary
receives a fair rate of return (as determined by the Board of Directors and set
forth in an Officers' Certificate delivered to the Transfer Agent) above its
expenses of providing such services; (vii) any transaction entered into in the
ordinary course of business between the Company or any Restricted Subsidiary
and any Unrestricted Subsidiary or any Affiliate (provided that in the case of
this clause (vii), such agreements are on terms that are no less favorable to

been obtained at the time of such transaction in an arm's-length transaction
with an unrelated third party) and (viii) Restricted Payments that are
permitted by the covenant described above under "--Restricted Payments."
 
 Business Activities
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, engage in any business other than a Permitted Business.
 
 Reports
 
  Whether or not required by the rules and regulations of the Commission, so
long as any Preferred Stock is outstanding, the Company will furnish to the
Holders of the Preferred Stock (i) all quarterly and annual financial
information that would be required to be contained in a filing with the
Commission on Forms 10-Q
 
                                       96
<PAGE>
 
and 10-K if the Company was required to file such Forms, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" that describes the financial condition and results of operations of
the Company and its consolidated Subsidiaries and, with respect to the annual
information only, a report thereon by the Company's certified independent
accountants, and (ii) all current reports that would be required to be filed
with the Commission on Form 8-K if the Company was required to file such
reports, in each case within the time periods specified in the Commission's
rules and regulations. In addition, following the consummation of the Exchange
Offer contemplated by the Registration Rights Agreement, whether or not
required by the rules and regulations of the Commission, the Company will file
a copy of all such information and reports with the Commission for public
availability within the time periods specified in the Commission's rules and
regulations (unless the Commission will not accept such a filing) and make such
information available to securities analysts and prospective investors upon
request. The Company will be deemed to have satisfied such requirements if GCL
files and provides reports, documents and information of the types otherwise so
required by the Commission, in each case within the applicable time periods,
and the Company is not required by the Commission to file such reports,
documents and information separately under the applicable rules and regulations
of the Commission (after giving effect to any exemptive relief) because of the
filings by GCL. Furthermore, the Company will agree that, for so long as any
Preferred Stock remains outstanding (and regardless of the immediately
preceding sentence), it will furnish to the Holders of the Preferred Stock and
to securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.
 
GOVERNING LAW
 
  The terms of the Preferred Stock and the Bye-laws will be governed by the
laws of Bermuda. The Company will submit to the jurisdiction of the U.S.
federal and New York state courts located in the Borough of Manhattan, City and
State of New York for purposes of all legal actions and proceedings instituted
in connection with the Preferred Stock and the Bye-laws. The Company has
appointed CT Corporation System as its authorized agent upon which process may
be served in any such action. See "Service of Process and Enforcement of
Liabilities."
 
CURRENCY INDEMNITY
 
  U.S. dollars are the sole currency of account and payment for all sums
payable by the Company under or in connection with the Preferred Stock (except
for dividends thereon prior to June 1, 2002 which may be paid in additional
shares of Preferred Stock), including damages. Any account received or
recovered in a currency other than dollars (whether as a result of, or the
enforcement of, a judgment or order of a court of any jurisdiction, in the
liquidation, dissolution or other winding-up of the affairs of the Company or
otherwise) by any Holder of Preferred Stock in respect of any sum expressed to
be due to it from the Company shall only constitute a discharge to the Company
to the extent of the dollar amount which the recipient is able to purchase with
the amount so received or recovered in that other currency on the date of that
receipt or recovery (or, if it is not practicable to make that purchase on that
date, on the first date on which it is practicable to do so). If that dollar
amount is less than the dollar amount expressed to be due to the recipient with
respect to the Preferred Stock, the Company shall indemnify it against any loss
sustained by it as a result. In any event, the Company shall indemnify the
recipient against the cost of making any such purchase. For the purposes of
this paragraph, it will be sufficient for the Holder of Preferred Stock to
certify in a satisfactory manner (indicating the sources of information used)
that it would have suffered a loss had an actual purchase of dollars been made
with the amount so received in that other currency on the date of receipt or
recovery (or, if a purchase of dollars on such date had not been practicable,
on the first date on which it would have been practicable, it being required
that the need for a change of date be certified in the manner mentioned above).
These indemnities constitute a separate and independent obligation from the
Company's other obligations, shall give rise to a separate and independent
cause of action, shall apply irrespective of any indulgence granted by any
Holder of Preferred Stock and shall constitute in full force and effect despite
any other judgment, order, claim or proof for a liquidated amount in respect of
any sum due under the Preferred Stock.

CERTAIN DEFINITIONS
 
  See "Description of Exchange Notes--Certain Definitions" for a description of
certain defined terms used herein.
 
BOOK-ENTRY, DELIVERY AND FORM
 
  The Exchange Preferred Stock will be represented by one or more permanent
global stock certificates in fully registered form (the "Global Security"),
which will be deposited with the Transfer Agent as custodian for DTC and
registered in the name of DTC or of a nominee of DTC.
 
  DTC has advised the Company that it is (i) a limited purpose company
organized under the laws of the State of New York, (ii) a "banking
organization" within the meaning of the New York Banking Law, (iii) a member of
the Federal Reserve System, (iv) a "clearing corporation" within the meaning of
the Uniform Commercial Code, as amended, and (v) a "clearing agency" registered
pursuant to Section 17A of the Exchange Act. DTC was created to hold securities
for its Participants and to facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
charges to the accounts of its Participants, thereby eliminating the need for
physical transfer and delivery of certificates. DTC's Participants include
securities brokers and dealers (including the initial purchasers), banks and
trust companies, clearing corporations and certain other organizations.
Indirect access to DTC's system is also available to other entities such as
banks, brokers, dealers and trust companies (collectively, the "Indirect
Participants") that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly. Investors who are not Participants
may beneficially own securities held by or on behalf of DTC only through
Participants or Indirect Participants.
 
  The Company expects that pursuant to procedures established by DTC (i) upon
issuance of a Global Security, DTC will credit, on its internal system, the
aggregate Liquidation Preference of the Exchange Preferred Stock of the
individual beneficial interests represented by such Global Security to the
respective accounts of persons who have accounts with such depository and (ii)
ownership of beneficial interests in such Global Security will be shown on, and
the transfer of such ownership will be effected only though, records maintained
by DTC (with respect to interest of Participants) and the records of
Participants and Indirect Participants (with respect to interests of persons
other than Participants).
 
  The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of securities is definitive form.
Accordingly, the ability to transfer interests in the Preferred Stock
represented by a Global Security to such persons may be limited. In addition,
because DTC can act only on behalf of its Participants, who in turn act on
behalf of persons who hold interests through Participants, the ability of a
person having an interest in Preferred Stock represented by a Global Security
to pledge or transfer such interest to persons or entities that do not
participate in DTC's system, or to otherwise take actions in respect of such
interest, may be affected by the lack of a physical definitive security in
respect of such interest.
 
  So long as DTC or its nominee is the registered owner of a Global Security,
DTC or such nominee, as the case may be, will be considered to be the sole
owner or holder of the Preferred Stock represented by the Global Security for
all purposes under the Bye-laws. Except as provided below, owners of beneficial
interests in a Global Security will not be entitled to have Exchange Preferred
Stock represented by such Global Security registered in their names, will not
receive or be entitled to receive physical delivery of Exchange Preferred Stock
certificates, and will not be considered the owners or holders thereof under
the Bye-laws for any purpose. Accordingly, each holder owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
holder is not a Participant or an Indirect Participant, on the procedures of
the Participant through which such holder owns its interest, to exercise any
rights of a holder of Exchange Preferred Stock under the Bye-laws or such
Global Security. The Company understands that under existing industry practice,
in the event that the Company requests any action of holders of Exchange
Preferred Stock, or a holder that is an owner of a beneficial interest in a
Global Security desires to take any action that DTC, as the holder of such
Global
 
                                       98
<PAGE>
 
Security, is entitled to take, DTC would authorize the Participants to take
such action and the Participants would authorize holders owning through such
Participants to take such action or would otherwise act upon the instruction of
such holders. Neither the Company nor the Transfer Agent will have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, Exchange Preferred Stock by DTC, or for
maintaining, supervising or reviewing any records of DTC relating to such
Exchange Preferred Stock.
 
  Payments with respect to the Liquidation Preference of and dividends on the
Preferred Stock represented by a Global Security registered in the name of DTC
or its nominee on the applicable record date will be payable at the direction
of DTC or its nominee in its capacity as the registered holder of the Global
Security representing the Exchange Preferred Stock. Under the terms of the Bye-
laws, the Company may treat the persons in whose names the Exchange Preferred
Stock, including the Global Security, are registered as the owners thereof for
the purpose of receiving payment thereon and for any and all other purposes
whatsoever. Accordingly, neither the Company nor the Transfer Agent has or will
have any responsibility or liability for the payment of such amounts to owners
of beneficial interests in a Global Security. Payments by the Participants and
the Indirect Participants to the owners of beneficial interests in a Global
Security will be governed by standing instructions and customary industry
practice and will be the responsibility of the Participants or the Indirect
Participants and DTC.
 
  DTC management is aware that some computer applications, systems, and the
like for processing data ("Systems") 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 (the "Industry") 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:
(i) impress upon them the importance of such services being Year 2000
compliant; and (ii) 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.

                         DESCRIPTION OF EXCHANGE NOTES
 
GENERAL
 
  If and when issued, the New Exchange Notes will be issued pursuant to an
indenture, to be dated as of the date of first issuance (the "Exchange Date")
of the New Exchange Notes (the "Indenture"), between the Company and a trustee.
The terms of the New Exchange Notes will include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"). The New Exchange Notes will be
subject to all such terms, and Holders of Exchange Notes are referred to the
Indenture and the Trust Indenture Act for a statement thereof. A copy of a form
of the Indenture is an exhibit to the registration statement of which this
prospectus is a part. The following summary of the material provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, including the definitions therein of certain terms
used below. The definitions of certain terms used in the following summary are
set forth below under "--Certain Definitions." For purposes of this summary,
the term "Company" refers only to Global Crossing Holdings Ltd. and not to any
of its Subsidiaries or GCL, and references to the Notes shall be deemed to
include the Old Exchange Notes and the New Exchange Notes.
 
TERMS OF NOTES
 
  The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to all existing and future Senior Debt. As of
September 30, 1998 the Company would have had Senior Debt outstanding of
approximately $1,213 million. The Indenture will permit the Company to incur
additional Senior Debt in the future.
 
  The Company conducts substantially all of its operations through its
Subsidiaries and, therefore, the Company is dependent on the cash flow of its
Subsidiaries to meet its obligations, including its obligations with respect to
the Notes. The Notes will be effectively subordinated to all Indebtedness and
other liabilities and commitments (including trade payables and lease
obligations) of the Company's Subsidiaries. Any right of the Company to receive
assets of any of its Subsidiaries upon the latter's liquidation or
reorganization (and the consequent right of the Holders of the Notes to
participate in those assets) will be effectively subordinated to the claims of
that Subsidiary's creditors, except to the extent that the Company is itself
recognized as a creditor of such Subsidiary, in which case the claims of the
Company would still be subordinate to any security in the assets of such
Subsidiary and any indebtedness of such Subsidiary that is senior to that held
by the Company. As of September 30, 1998, the Company's Subsidiaries had
approximately $531.4 million of Indebtedness and other liabilities (including
trade payables and lease obligations) outstanding, to which the Notes would
have been effectively subordinated had they been outstanding on September 30,
1998. See "Risk Factors--Covenant Restrictions."
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Notes will mature on December 1, 2008. Interest on the Notes will accrue
at the rate of 10 1/2% per annum and will be payable semi-annually in arrears
on June 1 and December 1 of each year that the Notes are outstanding to Holders
of record on the immediately preceding May 15 and November 15. Before June 1,
2002, the Company may elect to pay interest in cash or additional Exchange
Notes. On or after June 1, 2002, the Company is required to pay interest only
in cash. Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of
original issuance. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Principal, premium, if any, and interest on
the Notes will be payable at the office or agency of the Company maintained for
such purpose within the City and State of New York or, at the option of the
Company, payment of interest on the Notes may be made by check mailed to the
Holders of the Notes at their respective addresses set forth in the register of
Holders of Notes; provided that all payments of principal, premium, if any, and
interest on Notes the Holders of which have given wire transfer instructions to
the Company will be required to be made by wire transfer of
 
                                      100
<PAGE>
 
immediately available funds to the accounts specified by the Holders thereof.
Until otherwise designated by the Company, the Company's office or agency in
New York will be the office of the Trustee maintained for such purpose. The
Notes will be issued in denominations of $1,000 and integral multiples thereof.
The Trustee initially will be Paying Agent and Registrar under the Indenture,
and the Company may act as Paying Agent or Registrar under the Indenture.
 
  The interest rate on the Notes is subject to increase under certain
circumstances, as set forth herein under "--Exchange Offer; Registration
Rights." All references herein to interest shall be deemed to include any
special interest which may become payable on the Notes.
 
SUBORDINATION
 
  The payment of principal of, premium, if any, and interest on the Notes will
be subordinated in right of payment, as set forth in the Indenture, to the
prior payment in full in cash of all Senior Debt, whether outstanding on the
date of the Indenture or thereafter incurred.
 
  Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshaling of the Company's
assets and liabilities, the holders of Senior Debt will be entitled to receive
payment in full in cash of all Obligations due in respect of such Senior Debt
(including interest after the commencement of any such proceeding at the rate
specified in the applicable Senior Debt) before the Holders of the Notes will
be entitled to receive any payment with respect to the Notes, and until all
Obligations with respect to Senior Debt are paid in full, in cash, any
distribution to which the Holders of the Notes would be entitled shall be made
to the holders of Senior Debt (except that Holders of the Notes may receive and
retain Permitted Junior Securities and payments made from the trust described
below under "--Legal Defeasance and Covenant Defeasance").
 
  The Company also may not make any payment upon or in respect of the Notes
(except in Permitted Junior Securities or from the trust described below under
"--Legal Defeasance and Covenant Defeasance") if (i) a default in the payment
of the principal of, premium, if any, or interest on Designated Senior Debt
occurs and is continuing beyond any applicable period of grace or (ii) any
other default occurs and is continuing with respect to Designated Senior Debt
that permits holders of the Designated Senior Debt as to which such default
relates to accelerate its maturity and the Trustee receives a notice of such
default (a "Payment Blockage Notice") from the Company or the holders of any
Designated Senior Debt. Payments on the Notes may and shall be resumed (a) in
the case of a payment default, upon the date on which such default is cured or
waived and (b) in case of a nonpayment default, the earlier of the date on
which such nonpayment default is cured or waived or 179 days after the date on
which the applicable Payment Blockage Notice is received, unless the maturity
of any Designated Senior Debt has been accelerated. No new period of payment
blockage may be commenced unless and until (i) 360 days have elapsed since the
effectiveness of the immediately prior Payment Blockage Notice and (ii) all
scheduled payments of principal, premium, if any, and interest on the Notes
that have come due have been paid in full in cash. No nonpayment default that
existed or was continuing on the date of delivery of any Payment Blockage
Notice to the Trustee shall be, or be made, the basis for a subsequent Payment
Blockage Notice unless such default shall have been waived for a period of not
less than 90 days.
 
  The Indenture will further require that the Company promptly notify holders
of Senior Debt if payment of the Notes is accelerated because of an Event of
Default.
 
  As a result of the subordination provisions described above, in the event of
a liquidation or insolvency, Holders of the Notes may recover less ratably than
creditors of the Company who are holders of Senior Debt. See "Risk Factors--
Ranking of Securities; Holding Company Structure; Dividend Payment
Restrictions."
 
OPTIONAL REDEMPTION
 
  Except as set forth below and under "--Optional Tax Redemption," the Notes
will not be redeemable at the Company's option prior to December 1, 2003.
Thereafter, the Notes will be subject to redemption at any
 
                                      101
<PAGE>
 
time at the option of the Company, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below, plus accrued and unpaid
interest thereon to the applicable redemption date, if redeemed during the
twelve-month period beginning on December 1 of the years indicated below:
 
<TABLE>
<CAPTION>
            YEAR                               PERCENTAGE
            ----                               ----------

</TABLE>
 
  Notwithstanding the foregoing, at any time prior to December 1, 2001, the
Company may, on any one or more occasions, redeem up to 35% of the aggregate
principal amount of Notes originally issued pursuant to the Indenture at a
redemption price equal to 110.500% of the principal amount thereof, plus
accrued and unpaid interest thereon to the redemption date, with the net cash
proceeds received from one or more equity offerings made by the Company or GCL
(to the extent such net cash proceeds received by GCL were contributed to the
Company as common equity capital); provided that at least 65% of the then
effective aggregate principal amount of Notes originally issued pursuant to the
Indenture remains outstanding immediately after the occurrence of any such
redemption. The Company may make any such redemption upon not less than 30 nor
more than 60 days' notice (but in no event more than 90 days after the closing
of the related equity offering). Any such notice may be given prior to the
completion of the related equity offering and any such redemption may, at the
Company's discretion, be subject to the satisfaction of one or more conditions
precedent, including, but not limited to, the completion of the related equity
offering.
 
  In addition, at any time prior to December 1, 2003, the Notes may also be
redeemed at the option of the Company, in whole but not in part, upon the
occurrence of a Change of Control, upon not less than 30 nor more than 60 days'
prior notice (but in no event may any such redemption occur more than 90 days
after the occurrence of such Change of Control) mailed by first-class mail to
each Holder's registered address, at a redemption price equal to 100% of the
principal amount thereof, plus the Applicable Premium as of, and accrued and
unpaid interest thereon to, the date of redemption (the "Redemption Date).
 
  "Applicable Premium" means, with respect to any Note on any Redemption Date,
the greater of (i) 1.0% of the principal amount of such Note or (ii) the excess
of (A) the present value at such Redemption Date of (1) the redemption price of
such Note at December 1, 2003 (such redemption price being set forth in the
table above) plus (2) all required interest payments due on such Note through
December 1, 2003 (excluding accrued but unpaid interest), computed using a
discount rate equal to the Treasury Rate plus 50 basis points over (B) the
principal amount of such Note, if greater.
 
  "Treasury Rate" means, as of any Redemption Date, the yield to maturity as of
such Redemption Date of United States Treasury securities with a constant
maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two
Business Days prior to the Redemption Date (or, if such Statistical Release is
no longer published, any publicly available source of similar market data))
most nearly equal to the period from the Redemption Date to December 1, 2003;
provided, however, that if the period from the Redemption Date to December 1,
2003 is less than one year, the weekly average yield on actually traded United
States Treasury securities adjusted to a constant maturity of one year shall be
used.
 
OPTIONAL TAX REDEMPTION
 
  The Notes will be subject to redemption at the option of the Company or a
successor corporation at any time, in whole but not in part, upon not less than
30 nor more than 60 days' notice, at a redemption price equal to the principal
amount thereof, plus accrued and unpaid interest thereon to the redemption date
if, as a result
 
                                      102
<PAGE>
 
of any change in or amendment to the laws or any regulations or ruling
promulgated thereunder of (x) Bermuda or any political subdivision or
governmental authority thereof or therein having the power to tax, (y) any
jurisdiction, other than the United States, from or through which payment on
the Notes is made by the Company or a successor corporation, or its paying
agent in its capacity as such or any political subdivision or governmental
authority thereof or therein having the power to tax or (z) any other
jurisdiction, other than the United States, in which the Company or a successor
corporation is organized, or any political subdivision or governmental
authority thereof or therein having the power to tax, or any change in the
official application or interpretation of such laws, regulations or rulings, or
any change in the official application or interpretation of, or any execution
of or amendment to, any treaty or treaties affecting taxation to which such
jurisdiction (or such political subdivision or taxing authority) is a party (a
"Change in Tax Law"), which becomes effective on or after the Issue Date, the
Company or a successor corporation is or would be required on the next
succeeding interest payment date to pay Additional Amounts with respect to the
Notes (as described under "--Payment of Additional Amounts"), and the payment
of such Additional Amounts cannot be avoided by the use of any reasonable
measures available to the Company or a successor corporation.
 
  In addition, the Notes will be subject to redemption at the option of the
Company at any time, in whole but not in part, upon not less than 30 nor more
than 60 days' notice, at a redemption price equal to the principal amount
thereof, plus accrued and unpaid interest thereon to the redemption date, if
the Person formed by a consolidation or amalgamation of the Company or into
which the Company is merged or to which the Company conveys, transfers or
leases its properties and assets substantially as an entirety is required, as a
consequence of such consolidation, amalgamation, merger, conveyance, transfer
or lease and as a consequence of a Change in Tax Law occurring after the date
of such consolidation, amalgamation, merger, conveyance, transfer or lease, to
pay Additional Amounts in respect of any tax, assessment or governmental charge
imposed on any Holder of Notes.
 
PAYMENT OF ADDITIONAL AMOUNTS
 
  If any deduction or withholding for any present or future taxes, assessments
or other governmental charges of (x) Bermuda or any political subdivision or
governmental authority thereof or therein having power to tax, (y) any
jurisdiction, other than the United States, from or through which payment on
the Notes is made by the Company or a successor corporation, or its paying
agent in its capacity as such or any political subdivision or governmental
authority thereof or therein having the power to tax or (z) any other
jurisdiction, other than the United States, in which the Company or a successor
corporation is organized, or any political subdivision or governmental
authority thereof or therein having the power to tax shall at any time be
required by such jurisdiction (or any such political subdivision or taxing
authority) in respect of any amounts to be paid by the Company or a successor
corporation under the Notes, the Company or a successor corporation will pay to
each Holder of Notes as additional interest, such additional amounts
("Additional Amounts") as may be necessary in order that the net amounts paid
to such holder of such Notes who, with respect to any such tax, assessment or
other governmental charge, is not resident in, or a citizen of, such
jurisdiction, after such deduction or withholding, shall be not less than the
amount specified in such Notes to which such Holder is entitled; provided,
however, that the Company or a successor corporation shall not be required to
make any payment 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 (or between a fiduciary, settlor, beneficiary, member
  or shareholder of, or possessor of a power over, such Holder, if such
  Holder is an estate, trust, partnership, limited liability company or
  corporation) and the taxing jurisdiction or any political subdivision or
  territory or possession thereof or area subject to its jurisdiction,
  including, without limitation, such Holder (or such fiduciary, settlor,
  beneficiary, member, shareholder 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 a permanent establishment
  therein, (b) the presentation of a Note (where presentation is required)
  for payment on a date more than 30 days after (x) the date on which such
 
                                      103
<PAGE>
 
  payment became due and payable or (y) the date on which payment thereof is
  duly provided for, whichever occurs later, or (c) the presentation of a
  Note for payment in Bermuda or any political subdivision thereof or
  therein, unless such Note could not have been presented for payment
  elsewhere;
 
    (ii) 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 payable
  otherwise than by withholding from payment of principal of, premium, if
  any, or any interest on the Notes;
 
    (iv) 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 request of the Company addressed to the Holder
  (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; or
 
    (v) Any combination of items (i), (ii), (iii) and (iv) above;
 
nor shall Additional Amounts be paid with respect to any payment of the
principal of, or any premium or interest on, any Note to any Holder who is a
fiduciary or partnership or limited liability company or other than the sole
beneficial owner of such payment to the extent such payment would be required
by the laws of (x) Bermuda or any political subdivision or governmental
authority thereof or therein having the power to tax, (y) any jurisdiction,
other than the United States, from or through which payment on the Notes is
made by the Company or a successor corporation, or its paying agent in its
capacity as such or any political subdivision or governmental authority thereof
or therein having the power to tax or (z) any other jurisdiction, other than
the United States, in which the Company or a successor corporation is
organized, or any political subdivision or governmental authority thereof or
therein having the power to tax to be included in the income for tax purposes
of a beneficiary or settlor with respect to such fiduciary or a member of such
partnership, limited liability company or beneficial owner who would not have
been entitled to such Additional Amounts had it been the Holder of such Note.
 
  The Company shall provide the Trustee with the official acknowledgment of the
relevant taxing authority (or, if such acknowledgment is not available, a
certified copy thereof) evidencing the payment of the withholding taxes, if
any, by the Company. Copies of such documentation shall be made available to
the Holders of the Notes or the Paying Agent, as applicable, upon request
therefor.
 
  All references herein to principal of, premium, if any, and interest on the
Notes shall include any Additional Amounts payable by the Company in respect of
such principal, such premium, if any, and such interest.
 
SELECTION AND NOTICE
 
  If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the Notes are then listed, or, if the Notes are not so then listed, on a pro
rata basis, by lot or by such method as the Trustee shall deem fair and
appropriate; provided that no Notes of $1,000 or less shall be redeemed in
part. Notices of redemption shall be mailed by first class mail at least 30 but
not more than 60 days prior to the redemption date to each Holder of Notes to
be redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in
 
                                      104
<PAGE>
 
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Note. Notes called
for redemption will become due on the date fixed for redemption. On and after
the redemption date, interest will cease to accrue on Notes or portions thereof
called for redemption.
 
MANDATORY REDEMPTION
 
  Except as set forth below under "--Repurchase at the Option of Holders," the
Company will not be required to make mandatory redemption or sinking fund
payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
 Change of Control
 
  Upon the occurrence of a Change of Control, each Holder of Notes will have
the right to require the Company to purchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") at a purchase price in cash
(the "Change of Control Payment") equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon to the date of
purchase (subject to the right of Holders of record on the relevant record date
to receive interest due on the relevant interest payment date); provided,
however, that the Company shall not be obligated to repurchase Notes pursuant
to this covenant in the event that it has exercised its rights to redeem all of
the Notes as described above under "--Optional Redemption." Within 30 days
following any Change of Control, the Company will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of
Control and offering to purchase Notes on the date specified in such notice,
which date shall be no earlier than 30 and no later than 60 days from the date
such notice is mailed (the "Change of Control Payment Date"), in accordance
with 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 to the extent such
laws and regulations are applicable in connection with the purchase of Notes as
a result of a Change of Control. To the extent that the provisions of any
securities laws or regulations conflict with any of the provisions of this
covenant, the Company will comply with the applicable securities laws and
regulations and will be deemed not to have breached its obligations under this
covenant by virtue thereof.
 
  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 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 or deliver to each Holder of Notes
so tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail or deliver (or cause to be transferred by book
entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of Notes surrendered, if any; provided that each such new Note will be
in a principal amount of $1,000 or an integral multiple thereof. The Indenture
will provide that, prior to complying with the provisions of this covenant, but
in any event within 90 days following a Change of Control, the Company will
either repay all outstanding Senior Debt or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Debt to permit the
repurchase of Notes required by this covenant. 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 Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of Control, the Indenture will not
contain provisions that permit the Holders of the Notes to require that the
Company purchase or
 
                                      105
<PAGE>
 
redeem the Notes in the event of a takeover, recapitalization or similar
transaction. In addition, due to a Change of Control repayment provision in the
Senior Notes Indenture, the Company may be unable to repurchase all of the
Notes tendered upon the occurrence of a Change of Control. Furthermore, the
Company's ability to purchase Notes upon a Change of Control may be limited by
the Company's then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any such required
purchases. See "Risk Factors--Purchase of Securities Upon a Change of Control."
 
  Any future credit agreements or other agreements relating to Senior Debt to
which the Company becomes a party may contain provisions that prohibit or
restrict the Company from repurchasing Notes. In the event a Change of Control
occurs at a time when the Company is prohibited or restricted from purchasing
Notes, the Company could seek the consent of its lenders to the purchase of
Notes or could attempt to refinance the borrowings that contain such
prohibition or restriction. If the Company does not obtain such a consent or
repay such borrowings, the Company will remain prohibited or restricted from
purchasing Notes. In such case, the Company's failure to purchase tendered
Notes would constitute an Event of Default under the Indenture which would, in
turn, likely constitute a default under any future credit agreement or other
agreements relating to Senior Debt to which the Company becomes a party. In
such circumstances, the subordination provisions in the Indenture would likely
restrict payments to the Holders of Notes.
 
  The Company will not be required to make a Change of Control Offer upon the
occurrence of 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.
 
 Asset Sales
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, consummate any Asset Sale, unless (i) the Company
(or such Restricted Subsidiary, as the case may be) receives consideration at
the time of such Asset Sale at least equal to the fair market value (as
determined in good faith by the Board of Directors (including as to the value
of all noncash consideration) and set forth in an Officer's Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (ii) at least 75% of the consideration therefor is in
the form of cash and/or Cash Equivalents, and (iii) the Net Proceeds received
by the Company (or such Restricted Subsidiary, as the case may be) from such
Asset Sale are applied within 360 days following the receipt of such Net
Proceeds (a) first, to the extent the Company (or such Restricted Subsidiary,
as the case may be) elects, to the redemption or repurchase of outstanding
Senior Debt and (b) to the extent of the balance of such Net Proceeds after
application as described in (a) above and to the extent the Company (or such
Restricted Subsidiary, as the case may be) elects, to reinvest, or enter into a
legally binding agreement to reinvest, such Net Proceeds (or any portion
thereof) in assets that are used or useful in a Permitted Business. The balance
of such Net Proceeds, after the application of such Net Proceeds as described
in the immediately preceding clauses (a) and (b), shall constitute "Excess
Proceeds."
 
  When the aggregate amount of Excess Proceeds equals or exceeds $15.0 million
(taking into account income earned on such Excess Proceeds), the Company will
be required to make an offer to all Holders of Notes and pari passu
Indebtedness (an "Asset Sale Offer") to purchase the maximum principal amount
of Notes and pari passu Indebtedness that may be purchased out of the Excess
Proceeds, at a purchase price in cash in an amount equal to 100% of the
principal amount thereof, plus accrued and unpaid interest thereon to the date
of purchase, in accordance with the procedures set forth in the Indenture and
the agreements governing such pari passu Indebtedness. To the extent that 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 pari passu
Indebtedness tendered into such Asset Sale Offer surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and
pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of
such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero for
purposes of the first sentence of this paragraph.
 
                                      106
<PAGE>
 
  The amount of (x) any liabilities (as shown on the Company's (or such
Restricted Subsidiary's, as the case may be) most recent balance sheet) of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any guarantee
thereof) that are assumed by the transferee of any such assets pursuant to an
agreement that releases the Company or any Restricted Subsidiary from all
liability in respect thereof, (y) Indebtedness of any Restricted Subsidiary
that is no longer a Restricted Subsidiary as a result of such Asset Sale, to
the extent that the Company and each other Restricted Subsidiary are released
from any guarantee of payment of the principal amount of such Indebtedness in
connection with such Asset Sale and (z) any securities, notes or other
obligations received by the Company (or such Restricted Subsidiary, as the case
may be) from such transferee that are contemporaneously (subject to ordinary
settlement periods) converted by the Company (or such Restricted Subsidiary, as
the case may be) into cash and/or Cash Equivalents (to the extent of the cash
and/or Cash Equivalents received), will be deemed to be cash and/or Cash
Equivalents for purposes of this provision.
 
CERTAIN COVENANTS
 
 Restricted Payments
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly: (i) declare or pay any dividend or make any other
payment or distribution on account of the Company's or any of its Restricted
Subsidiaries' Equity Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the Company or any of its
Restricted Subsidiaries) or to the direct or indirect holders of the Company's
or any of its Restricted Subsidiaries' Equity Interests (other than dividends
or distributions payable in Equity Interests (other than Disqualified Stock) of
the Company or to the Company or a Restricted Subsidiary of the Company); (ii)
purchase, redeem or otherwise acquire or retire for value (including, without
limitation, in connection with any merger or consolidation involving the
Company) any Equity Interests of the Company or any direct or indirect parent
of the Company (other than any such Equity Interests owned by the Company or
any Wholly Owned Restricted Subsidiary of the Company); (iii) make any payment
on or with respect to, or purchase, redeem, defease or otherwise acquire or
retire for value any Indebtedness that is subordinated to the Notes, except a
payment of interest or principal at Stated Maturity; or (iv) make any
Restricted Investment (all such payments and other actions set forth in clauses
(i) through (iv) above being collectively referred to as "Restricted
Payments"), unless:
 
    (a) at the time of and after giving effect to such Restricted Payment, no
  Default or Event of Default shall have occurred and be continuing or would
  occur as a consequence thereof;
 
    (b) in the case of clauses (i), (ii) and (iii) above, and, in the case of
  any Restricted Investment that is not an Investment in a Permitted
  Business, the Company would, at the time of such Restricted Payment and
  after giving pro forma effect thereto as if such Restricted Payment had
  been made at the beginning of the applicable four-quarter period, have been
  permitted to incur at least $1.00 of additional Indebtedness pursuant to
  either clause (i) or (ii) of the first paragraph of the covenant described
  below under the caption "--Incurrence of Indebtedness and Issuance of
  Preferred Stock"; and
 
    (c) such Restricted Payment, together with the aggregate amount of all
  other Restricted Payments made by the Company and its Restricted
  Subsidiaries and any Permitted Investments made pursuant to clause (h) of
  the definition of Permitted Investments after the date hereof (excluding
  Restricted Payments permitted by clauses (ii), (iii), (iv), (vi), (vii) and
  (viii) (but, in the case of clause (viii), only to the extent that such
  Restricted Payments are reflected as an expense on the income statements of
  GCL) of the next succeeding paragraph), is less than the sum, without

  determined above) of property or assets received by the Company or any
  Restricted Subsidiary upon such conversion or exchange, plus (iii) the
  aggregate amount equal to the net reduction in Investments in Unrestricted

  the amount of proceeds (net of any cost of disposition) equal to the
  initial amount of such Restricted Investment.
 
  The foregoing provisions will not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the foregoing provisions;
(ii) the redemption, repurchase, retirement, defeasance or other acquisition of
any subordinated Indebtedness or Equity Interests of the Company in exchange

(vi) Investments in the PC-1 Companies and Global Access Limited in an

net cash proceeds that are utilized for any such Investment shall be excluded
from clause (c)(ii) of the preceding paragraph) plus 50% of the net gain
realized and not otherwise included in Consolidated Cash Flow from the sale of
Restricted Investments ; (viii) the payment of any dividend or the making of
any distribution to GCL by the Company or any Restricted Subsidiary to pay or
permit GCL to pay any GCL Expenses or any Related Taxes; and (ix) other

  The Board of Directors may not designate any Subsidiary of the Company (other
than a newly created Subsidiary in which no Investment has previously been made
(other than the amount required to capitalize such Subsidiary in connection
with its organization)) as an Unrestricted Subsidiary (a "Designation") unless:
(i) no Default or Event of Default shall have occurred and be continuing at the
time of or after giving effect to such Designation; (ii) the Company would,
immediately after giving effect to such Designation, have been permitted to
incur at least $1.00 of additional Indebtedness pursuant to either clause (i)
or (ii) of the first paragraph of the covenant described below under "--
Incurrence of Indebtedness and Issuance of Preferred Stock" and (iii) the
Company would not be prohibited under the Indenture from making an Investment
at the time of such
 
                                      108
<PAGE>
 
Designation (assuming the effectiveness of such Designation for purposes of
clauses (a) and (b) of the first paragraph of this covenant) in an amount equal
to the fair market value of the net Investment of the Company or any other
Restricted Subsidiary in such Subsidiary on such date.
 
  In the event of any such Designation, 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
will reduce the amount available for Restricted Payments under the first
paragraph of this covenant or Permitted Investments, as applicable. All such
outstanding Investments will be deemed to constitute Restricted Payments in an
amount equal to the fair market value of such Investments at the time of such
Designation.
 
  The Indenture will further provide that a Designation may be revoked (a
"Revocation") by a resolution of the Board of Directors delivered to the
Trustee, provided that the Company will not make any Revocation unless: (i) no
Default or Event of Default shall have occurred and be continuing at the time
of or after giving effect to such Designation; and (ii) all Liens and
Indebtedness of such Unrestricted Subsidiary outstanding immediately following
such Revocation would, if incurred at such time, have been permitted to be
incurred at such time for all purposes under the Indenture.
 
  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 asset(s) or securities that are required to be
valued by this covenant shall be determined in good faith by the Board of
Directors (such determination to be based upon an opinion or appraisal issued
by an accounting, appraisal or investment banking firm of national standing if
such fair market value exceeds $15.0 million).
 
 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, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "incur") any Indebtedness (including Acquired Debt)
and the Company will not issue any Disqualified Stock and will not permit any
of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock and its Restricted Subsidiaries may
incur Indebtedness or issue Disqualified Stock or preferred stock if either:
 
    (i) the Consolidated Leverage Ratio is less than 5.5 to 1.0 (prior to
  December 1, 2001) or 5.0 to 1.0 (subsequent to December 1, 2001); or
 
    (ii) the Consolidated Capital Ratio is less than 2.5 to 1.0.
 
  Notwithstanding the foregoing, the provisions of the paragraph set forth

  Notes;

  any other Restricted Subsidiary (but only for so long as such Indebtedness
  is held by the Company or such Restricted Subsidiary);
 
    (d) The issuance by the Company of Preferred Stock to any Restricted
  Subsidiary or the issuance by any Restricted Subsidiary of Preferred Stock
  to the Company or any other Restricted Subsidiary (but only for so long as
  such preferred stock is held by the Company or such Restricted Subsidiary);
 
    (e) The incurrence by the Company or any of its Restricted Subsidiaries
  of Indebtedness pursuant to acquisitions of capacity made in the ordinary
  course of business;

  to be outstanding;
 
    (g) The incurrence by the Company or any of its Restricted Subsidiaries
  of Indebtedness of a Restricted Subsidiary incurred and outstanding on the

  by the Company (giving effect to such acquisition), the Company would have
  been able to incur $1.00 of additional Indebtedness pursuant to the
  immediately preceding paragraph;
 
    (h) The incurrence by the Company or any of its Restricted Subsidiaries
  of Permitted Refinancing Indebtedness in exchange for, or the net proceeds
  of which are used to refund, refinance or replace Indebtedness (other than

    (i) The incurrence by the Company or any of its Restricted Subsidiaries

  applicable) at any time outstanding, including all Permitted Refinancing
  Indebtedness incurred to refund, refinance or replace any Indebtedness
  incurred pursuant to this clause (i), not to exceed $50.0 million;
 
    (j) The incurrence of Indebtedness by a Receivables Entity in a Qualified
  Receivables Transaction, provided that the proceeds thereof are applied in
  accordance with the covenant described above under "--Repurchase at the
  Option of Holders--Asset Sales."
 
    (k) The incurrence by the Company or any Restricted Subsidiary of
  Purchase Money Indebtedness, provided that the amount of such Purchase
  Money Indebtedness does not exceed 100% of the cost of construction,
  installation, acquisition, lease, development, design, engineering,
  financing, testing, start-up, upgrade, completion or improvement of assets
  (together with related costs and expenses) used in the business of the
  Company or such Restricted Subsidiary;
 
    (l) Letters of Credit that are cash collateralized;
 
    (m) Letters of Credit in an aggregate principal amount equal to $200.0

  incurred pursuant to this clause (n); and
 
    (o) The guarantee by the Company or any Restricted Subsidiary of
  Indebtedness of the Company or any Restricted Subsidiary of the Company
  that was permitted to be incurred by another provision of this covenant.
 
 No Senior Subordinated Debt
 
  The Company will not, directly or indirectly, incur, create, issue, assume,
guarantee or otherwise become liable for any Indebtedness that is subordinated
or junior in right of payment to any Senior Debt and senior in any respect in
right of payment to the Notes.
 
 Liens
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, create, incur, assume or otherwise cause or suffer to exist or become
effective any Lien of any kind securing Indebtedness which is pari passu with
or subordinated to the Notes (other than Permitted Liens) upon any of their
property or assets, now
 
                                      110
<PAGE>
 
owned or hereafter acquired, unless all payments due under the Indenture and
the Notes are secured on an equal and ratable basis with (or prior to, in the
case of Indebtedness which is subordinated to the Notes) the obligations so
secured until such time as such obligations are no longer secured by a Lien.
 
 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 otherwise cause or suffer to exist or
become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(a) pay dividends or make any other distributions
to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock
or (2) with respect to any other interest or participation in, or measured by,
its profits, or (b) pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries or (iii) transfer any of its properties or assets
to the Company or any of its Restricted Subsidiaries. However, the foregoing
restrictions will not apply to encumbrances or restrictions existing under or
by reason of (a) Existing Indebtedness as in effect on the date hereof, (b)
agreements as in effect as of the date hereof, (c) Indebtedness incurred in
accordance with clause (g), (h), (i), (k) or (n) of the second paragraph of the
covenant set forth above under the caption "--Incurrence of Indebtedness and
Issuance of Preferred Stock," provided that such encumbrances or restrictions
are customary with respect to such types of Indebtedness (as determined in good
faith by the Chief Financial Officer of the Company) and provided further that
the provisions of such Indebtedness do not prohibit payments by the Company of
principal, premium, interest and Additional Amounts pursuant to the terms of
the Notes and the Indenture, (e) the Indenture and the Notes, (f) applicable
law, (g) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except to the extent such Indebtedness was
incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties
or assets of any Person, other than the Person, or the property or assets of
the Person, so acquired, provided, that in the case of Indebtedness, such
Indebtedness was permitted by the terms of the Indenture to be incurred, (h)
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices, (i) purchase money
obligations for property acquired in the ordinary course of business that

Subsidiary pending its sale or other disposition, (k) Permitted Refinancing
Indebtedness, provided that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are no more restrictive,
taken as a whole, than those contained in the agreements governing the
Indebtedness being refinanced, (l) Liens securing Indebtedness 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, (m)
provisions with respect to 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 (n) restrictions on cash or other
deposits or net worth imposed by customers under contracts entered into in the
ordinary course of business.
 
  Certain restrictions under credit facilities entered into, or expected to be
entered into, to finance Permitted Businesses will substantially limit the
payment of dividends or distributions to the Company until the Indebtedness
incurred under such facilities is retired. See "Risk Factors--Holding Company
Structure; Effective Subordination of the Securities" and "Description of
Certain Indebtedness--AC-1 Credit Facility."
 
 Merger, Consolidation, or Sale of Assets
 
  The Company may not, directly or indirectly, consolidate or merge with or
into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, convey or otherwise dispose of all or substantially all of
its properties or assets, in one or more related transactions, to another
Person unless: (i) the Company is the surviving corporation or the Person
formed by or surviving any such consolidation or merger
 
                                      111
<PAGE>
 
(if other than the Company) or to which such sale, assignment, transfer,
conveyance or other disposition shall have been made is a corporation organized
or existing under the laws of the United States, any state thereof or the
District of Columbia, or Bermuda; (ii) the Person formed by or surviving any
such consolidation or merger (if other than the Company) or the Person to which
such sale, assignment, transfer, conveyance or other disposition shall have
been made assumes all the obligations of the Company under the Registration
Agreement, the Notes and the Indenture pursuant to a supplemental indenture in
a form reasonably satisfactory to the trustee; (iii) immediately after such
transaction no Default or Event of Default exists; and (iv) except in the case
of a merger of the Company with or into a Wholly Owned Restricted Subsidiary of
the Company, the Company or the Person formed by or surviving any such
consolidation or merger (if other than the Company), or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made (A)
will have Consolidated Net Worth immediately after the transaction equal to or
greater than the Consolidated Net Worth of the Company immediately preceding
the transaction and (B) will, immediately after such transaction and after
giving pro forma effect thereto and any related financing transactions as if
the same had occurred at the beginning of the applicable four-quarter period,
be permitted to incur at least $1.00 of additional Indebtedness pursuant to
either clause (i) or (ii) of the first paragraph of the covenant described
above under "--Incurrence of Indebtedness and Issuance of Preferred Stock." The
Indenture will also provide that 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. The provisions of this covenant will
not be applicable to a sale, assignment, transfer, conveyance or other
disposition of assets between or among the Company and its Wholly Owned
Restricted Subsidiaries.
 
 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 or assets 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 of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on terms that are not materially 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 an unrelated Person and (ii) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $25.0 million, the Company delivers to the Trustee a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction is approved by a majority of the disinterested
members of the Board of Directors and an opinion as to the fairness to the
Holders of such Affiliate Transaction from a financial point of view is
obtained from an accounting, appraisal or investment banking firm of national
standing. Notwithstanding the foregoing, the following items shall not be
deemed to be Affiliate Transactions: (i) (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

approved by the Board of Directors on the Issue Date, including any amendments
thereto (provided that the terms of such amendments are not materially less
favorable to the Company or the relevant Restricted Subsidiary than the terms
of such agreement prior to such amendment), (vi) transactions with respect to
capacity or dark fiber between the Company or any Restricted Subsidiary and any
Unrestricted Subsidiary or other Affiliate and joint sales and marketing
pursuant to an agreement or agreements between the
 
                                      112
<PAGE>
 
Company or any Restricted Subsidiary and any Unrestricted Subsidiary or other
Affiliate (provided that in the case of this clause (vi), such agreements are
on terms that are no less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained at the time of such
transaction in an arm's-length transaction with an unrelated third party or, in
the case of a transaction with an Unrestricted Subsidiary, are either (x)
entered into in connection with a transaction involving the selection by a
customer of cable system capacity entered into in the ordinary course of
business or (y) involve the provision by the Company or a Restricted Subsidiary
to an Unrestricted Subsidiary of sales and marketing services, operations,
administration and maintenance services or development services for which the
Company or such Restricted Subsidiary receives a fair rate of return (as
determined by the Board of Directors and set forth in an Officers' Certificate
delivered to the trustee) above its expenses of providing such services; (vii)
any transaction entered into in the ordinary course of business between the
Company or any Restricted Subsidiary and any Unrestricted Subsidiary or any
Affiliate (provided that in the case of this clause (vii), such agreements are
on terms that are no less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained at the time of such
transaction in an arm's-length transaction with an unrelated third party) and
(viii) Restricted Payments that are permitted by the covenant described above
under "--Restricted Payments."
 
 Business Activities
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, engage in any business other than a Permitted Business.
 
 Payments for Consent
 
  Neither the Company nor any of its Restricted Subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder of any 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 or is
paid to all Holders of the Notes that consent, waive or agree to amend such
terms or provisions of the Indenture or the Notes in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement.
 
 Reports
 
  Whether or not required by the rules and regulations of the Commission, so
long as any Notes are outstanding, the Company will furnish to the trustee and
the Holders of the Notes (i) all quarterly and annual financial information
that would be required to be contained in a filing with the Commission on Forms
10-Q and 10-K if the Company was required to file such Forms, including a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" that describes the financial condition and results of operations of
the Company and its consolidated Subsidiaries and, with respect to the annual
information only, a report thereon by the Company's certified independent
accountants, and (ii) all current reports that would be required to be filed
with the Commission on Form 8-K if the Company was required to file such
reports, in each case within the time periods specified in the Commission's
rules and regulations. In addition, following the consummation of the Exchange
Offer contemplated by the Registration Rights Agreement, whether or not
required by the rules and regulations of the Commission, the Company will file
a copy of all such information and reports with the Commission for public
availability within the time periods specified in the Commission's rules and
regulations (unless the Commission will not accept such a filing) and make such
information available to securities analysts and prospective investors upon
request. The Company will be deemed to have satisfied such requirements if GCL
files and provides reports, documents and information of the types otherwise so
required by the Commission, in each case within the applicable time periods,
and the Company is not required by the Commission to file such reports,
documents and information separately under the applicable rules and regulations
of the Commission (after giving effect to any exemptive relief) because of the
filings by GCL. Furthermore, the Company will agree that, for so long as any
Notes remain outstanding (and regardless of the immediately preceding
sentence), it will furnish to the Holders of the Notes and to securities
analysts and prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act
of 1933.

EVENTS OF DEFAULT AND REMEDIES
 
  The Indenture will provide that each of the following will constitute an
Event of Default: (i) default for 30 days in the payment when due of interest
on the Notes (whether or not prohibited by the subordination provisions of the
Indenture); (ii) default in the payment when due of the principal of, or
premium, if any, on, the Notes (whether or not prohibited by the subordination
provisions of the Indenture); (iii) failure by the Company or any of its
Restricted Subsidiaries to comply with the provisions described above under the
captions "--Repurchase at the Option of Holders--Change of Control," "--
Repurchase at the Option of Holders--Asset Sales," "--Certain Covenants--
Restricted Payments" or "--Certain Covenants--Incurrence of Indebtedness and
Issuance of Preferred Stock"; (iv) failure by the Company or any of its
Restricted Subsidiaries for 60 days after notice to comply with any of its
other agreements in the Indenture or the Notes; (v) 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 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, which default 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 the maturity of which has been
so accelerated, aggregates $25.0 million or more; (vi) failure by the Company
or any of its Restricted Subsidiaries to pay final judgments not subject to
appeal aggregating in excess of $25.0 million (net of applicable insurance
coverage which is acknowledged in writing by the insurer), which judgments are
not paid, discharged or stayed for a period of 60 days; and (vii) certain
events of bankruptcy or insolvency with respect to the Company or any of its
Restricted Subsidiaries.
 
  If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Notes may declare
all the Notes to be due and payable immediately. Notwithstanding the foregoing,
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, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of
the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal of, premium, if any, or interest on, the
Notes) if it determines that withholding notice is in their interest.
 
  In the case of any Event of Default occurring by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding payment of the premium that the Company would have had to
pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium also
will become immediately due and payable, to the extent permitted by law, upon
the acceleration of the Notes. If an Event of Default occurs prior to December
1, 2003 by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to December 1, 2003, then the premium specified
in the Indenture also will become immediately due and payable, to the extent
permitted by law, upon the acceleration of the Notes.
 
  The Holders of a majority in aggregate principal amount of the then
outstanding Notes by notice to the Trustee may on behalf of the Holders of all
of the Notes waive 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 principal of, premium, if any, or interest on, the
Notes.
 
  The Company will be required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company will be required upon
becoming aware of any Default or Event of Default to deliver to the Trustee a
statement specifying such Default or Event of Default.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATORS OR
SHAREHOLDERS
 
  No director, officer, employee, incorporator or shareholder of the Company,
as such, will have any liability for any obligations of the Company with
respect to the Notes or the Indenture, or for any claim based on, or in respect
or by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note will waive and release any and all such liability. Such waiver
and release are part of the consideration for issuance of the Notes. Such
waiver may not be effective to waive liabilities under federal securities laws
and it is the view of the Commission that such a waiver is against public
policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Indenture will be discharged and canceled upon the delivery by the
Company to the Trustee for cancellation of all the Notes or upon irrevocable
deposit with the Trustee, within not more than one year prior to the redemption
of the Notes, or when the Notes are to be called for redemption within one year
under arrangements satisfactory to the Trustee, of funds sufficient for the
payment or redemption of all the Notes. In addition, the Indenture will provide
that the Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance"), except for: (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
on such Notes when such payments are due from the trust referred to below; (ii)
the Company's obligations with respect to the Notes concerning issuing
temporary Notes, registration of Exchange 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; (iii) the rights, powers, trusts, duties
and immunities of the Trustee, and the Company's obligations in connection
therewith; and (iv) the Legal Defeasance provisions of the Indenture. In
addition, the Company may, at its option and at any time, elect to have its
obligations released with respect to certain covenants that are contained in
the Indenture ("Covenant Defeasance") and, thereafter, any omission to comply
with such obligations will not constitute a Default or Event of Default. In the
event Covenant Defeasance occurs, certain events (but not including non-
payment, bankruptcy, receivership, rehabilitation or insolvency events)
described under "--Events of Default and Remedies" will no longer constitute an
Event of Default.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit, or cause to be deposited, 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, premium, if any, and
interest on the outstanding Notes on the stated maturity thereof 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; (ii) in the case of Legal Defeasance, the Company must deliver to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or since the Issue Date,
there has been a change in the applicable federal income tax law, in either
case to the effect that, and based thereon such opinion of counsel shall
confirm that, the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal
Defeasance, and will be subject to 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; (iii) in the case of Covenant Defeasance, the
Company must deliver to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance, and such Holders will be
subject to 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; (iv) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) or
insofar as Events of Default from bankruptcy or insolvency events are
concerned, at any time in the period ending on the 91st day after the date of
deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under,
 
                                      115
<PAGE>
 
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; (vi) the Company must
deliver to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee 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 and remedies generally; (vii) 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 the Notes over other creditors of the
Company, or with the intent of defeating, hindering, delaying or defrauding
creditors of the Company or others; (viii) the Company must deliver to the
Trustee an opinion of counsel in Bermuda reasonably acceptable to the Trustee
to the effect that the Holders of the outstanding Notes will not be adversely
affected under Bermuda law; and (ix) the Company must deliver to the trustee an
Officers' Certificate and an opinion of counsel in the United States reasonably
acceptable to the Trustee, each stating that all conditions precedent provided
for or relating to Legal Defeasance or Covenant Defeasance, as applicable, have
been complied with.
 
TRANSFER AND EXCHANGE
 
  A Holder may transfer or exchange Exchange Notes in accordance with the
procedures set forth in the Indenture. The registrar and the trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents, and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company will not be
required to transfer or exchange any Note selected for redemption. Also, the
Company will not be required to transfer or exchange any Note for a period of
15 days before (i) a selection of Notes to be redeemed, (ii) an interest
payment date or (iii) the mailing of notice of a Change of Control Offer or
Asset Sale Offer. The registered Holder of a Note will be treated as the owner
of it for all purposes under the Indenture.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  Except as provided in the next two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the then outstanding Notes (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Notes), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Notes).
 
  Without the consent of each Holder affected, such an amendment or waiver may
not (with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver; (ii) reduce the principal or change the fixed maturity of
any Note, or alter the redemption provisions of the Notes (other than
redemption provisions relating to the covenants described above under the
caption "--Repurchase at the Option of Holders"); (iii) reduce the rate of, or
change the time for, payment of interest on any Note; (iv) waive a Default or
Event of Default in the payment of principal of, 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 thereof and a waiver of
the payment default that resulted from such acceleration); (v) make any Note
payable in money other than that stated in the Notes; (vi) make any change in
the provisions of the Indenture relating to waivers of past Defaults or the
rights of Holders of the Notes to receive payments of principal of, premium, if
any, or interest on the Notes; (vii) waive a redemption payment with respect to
any Note (other than a payment required by one of the covenants described above
under the caption "--Repurchase at the Option of Holders"); or (viii) make any
change in the foregoing amendment and waiver provisions. In addition, any
amendment to the provisions of the Indenture which relate to subordination will
require the consent of the Holders of at least 75% in aggregate principal
amount of the Notes then outstanding if such amendment would adversely affect
the rights of the Holders of the Notes.
 
                                      116
<PAGE>
 
  Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company's obligations to Holders of Notes in the case of a
merger or consolidation or sale of all or substantially all of the Company's
assets, to make any change that would provide any additional rights or benefits
to the Holders of Notes or that does not adversely affect the legal rights
under the Indenture of any such Holder, or to comply with the requirements of
the Commission in order to effect or maintain the qualification of the
Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
  The Indenture contains certain limitations on the rights of the trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The trustee will be permitted to engage in
other transactions; however, if it acquires any conflicting interest, it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue, or resign.
 
  The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. In case an Event of Default shall occur (which shall not be
cured), 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 their own affairs. Subject
to such provisions, the Trustee will be under no obligation to exercise any of
its rights or powers under the Indenture at the request of any Holder of Notes,
unless such Holder shall have offered to the trustee security and indemnity
satisfactory to it against any loss, liability or expense.
 
GOVERNING LAW
 
  The Indenture and the Notes will be governed by and construed in accordance
with the laws of the State of New York.
 
  The Company will submit to the jurisdiction of the U.S. federal and New York
state courts located in the Borough of Manhattan, City and State of New York
for purposes of all legal actions and proceedings instituted in connection with
the Notes and the Indenture. The Company has appointed CT Corporation System as
its authorized agent upon which process may be served in any such action. See
"Service of Process and Enforcement of Liabilities."
 
CURRENCY INDEMNITY
 
  U.S. dollars are the sole currency of account and payment for all sums
payable by the Company under or in connection with the Notes, including
damages. Any account received or recovered in a currency other than dollars
(whether as a result of, or the enforcement of, a judgment or order of a court
of any jurisdiction, in the liquidation, dissolution or other winding-up of the
affairs of the Company or otherwise) by any Holder of a Note in respect of any
sum expressed to be due to it from the Company shall only constitute a
discharge to the Company to the extent of the dollar amount which the recipient
is able to purchase with the amount so received or recovered in that other
currency on the date of that receipt or recovery (or, if it is not practicable
to make that purchase on that date, on the first date on which it is
practicable to do so). If that dollar amount is less than the dollar amount
expressed to be due to the recipient under any Note, the Company shall
indemnify it against any loss sustained by it as a result. In any event, the
Company shall indemnify the recipient against the cost of making any such
purchase. For the purposes of this paragraph, it will be sufficient for the
Holder of a Note to certify in a satisfactory manner (indicating the sources of
information used) that it would have suffered a loss had an actual purchase of
dollars been made with the amount so received in that other currency on the
date of receipt or recovery (or, if a purchase of dollars on such date had not
been practicable, on the first date on which it would have been practicable, it
being required that the need for a change of date be certified in the manner
 
                                      117
<PAGE>
 
mentioned above). These indemnities constitute a separate and independent
obligation from the Company's other obligations, shall give rise to a separate
and independent cause of action, shall apply irrespective of any indulgence
granted by any Holder of a Note and shall constitute in full force and effect
despite any other judgment, order, claim or proof for a liquidated amount in
respect of any sum due under any Note.

person and do not have the right or ability by voting power, contract or

of the Company or GCL, (iii) the Company or GCL consolidates or merges with or

person more than 50% of the Voting Stock (measured by voting power rather than

use in its business, including, without limitation, for sale, lease, transfer,
conveyance or other disposition to any customer of the Company or any
Restricted Subsidiary shall not be deemed a disposition of assets for purposes
of this clause (iv).
 
  The definition of a 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 GCL or the Company and its Restricted Subsidiaries taken as a
whole, as such phrase is used in the Revised Model Business Corporation Act.
Although there is a developing body of case law interpreting the phrase
"substantially all," there is no precise established definition of such phrase
under applicable law. Accordingly, the ability of a Holder of Notes to require
the Company to purchase such Notes as a result of a sale, lease, transfer,
conveyance or other disposition of less than all of the assets of GCL or the
Company and its Restricted Subsidiaries taken as a whole to another Person or
group may be uncertain.

Restricted Subsidiaries, as of the date of any incurrence of Indebtedness or
issuance of Disqualified Stock, the ratio of (i) the aggregate consolidated
principal amount of Indebtedness outstanding and the liquidation preference of
Disqualified Stock as of the most recent quarterly or annual balance sheet
date, after giving pro forma effect to the incurrence of such Indebtedness or
the issuance of such Disqualified Stock and any other Indebtedness incurred and
Disqualified Stock issued since such balance sheet date, and the receipt and
application of the proceeds therefrom to (ii) Consolidated Net Worth as of such
balance sheet date after giving pro forma effect to the issuance of Equity
Interests (other than Disqualified Stock) issued since the balance sheet date
and the receipt and application of the proceeds therefrom.
 
  "Consolidated Cash Flow" means, with respect to the Company for any period,
the Consolidated Net Income of the Company and its Restricted Subsidiaries for
such period plus, to the extent that any of the following items were deducted
or added (without duplication) in computing such Consolidated Net Income, (i)
an amount equal to any extraordinary loss (less any gain) plus any net loss
(less any gain) realized in connection with any Asset Sale, plus (ii) provision
for taxes based on income or profits of the Company and its Restricted
Subsidiaries for such period, plus (iii) Consolidated Interest Expense of the
Company and its Restricted Subsidiaries for such period, whether paid or
accrued and whether or not capitalized, plus (iv) any Preferred Stock dividends
to the extent subtracted in arriving at net income, plus (v) depreciation,
amortization (including amortization of goodwill and other intangibles and the
amount of capacity available for sale charged to cost of sales), but excluding
amortization of prepaid cash expenses that were paid in a prior period) and
other non-cash expenses (excluding any such non-cash expense to the extent that
it represents an accrual of or reserve for cash expenses in any future period
or amortization of a prepaid cash expense that was paid in a prior period) of

cash items increasing such Consolidated Net Income for such period (other than

<PAGE>
 
course of business), plus (vii) any change in Deferred Revenue, in each case,
on a consolidated basis and determined in accordance with GAAP. Notwithstanding

depreciation and amortization and other non-cash expenses of, a Restricted
Subsidiary of the Company shall be added to Consolidated Net Income to compute
Consolidated Cash Flow of the Company only to the extent that a corresponding
amount would be permitted at the date of determination to be dividended to the
Company by such Restricted Subsidiary without prior governmental approval (that
has not been obtained), and without direct or indirect restriction pursuant to
the terms of its charter and all agreements (excluding agreements evidencing
Indebtedness incurred in accordance with clause (k) of "--Certain Covenants--
Incurrence of Indebtedness and Issuance of Preferred Stock", to which this
provision shall not apply), instruments, judgments, decrees, orders, statutes,
rules and governmental regulations applicable to that Restricted Subsidiary or
its shareholders.
 
  "Consolidated Interest Expense" for any Person means for any period the
consolidated interest expense included in a consolidated income statement
(without deduction of interest income) of such Person and its Consolidated
Subsidiaries for such period, including without limitation or duplication (or,
to the extent not so included, with the addition of), (i) amortization of debt
issuance costs and original issue discount, (ii) non-cash interest payments,
(iii) the interest component of any deferred payment obligations, (iv) the
interest component of all payments associated with Capital Lease Obligations,
(v) commissions, discounts and other fees and charges incurred in respect of
Letter of Credit or bankers' acceptance financings and (vi) net payments (if

application of the proceeds therefrom to (ii) Consolidated Cash Flow for the

Indebtedness or issuance of such Disqualified Stock for which consolidated
financial statements are available.
 
  "Consolidated Net Income" means, with respect to the Company for any period,
the aggregate of the net income of the Company and its Restricted Subsidiaries
for such period, on a consolidated basis, determined in accordance with GAAP,
plus, to the extent that any of the following items were deducted in computing
such Consolidated Net Income, (a) non-recurring, non-cash charges (other than
charges arising from write-downs of assets) and (b) non-cash compensation
charges arising from stock options or other similar employee benefit or
compensation plans; provided that (i) the net income (but not loss) of any
Restricted Subsidiary that is accounted for by the equity method of accounting
shall be included only to the extent of the amount of dividends or
distributions paid in cash to the Company or a Wholly Owned Restricted
Subsidiary thereof by such Restricted Subsidiary, (ii) the net income (or loss)
of any Person that is not a Restricted Subsidiary shall be included only to the
extent of the amount of dividends or other distributions actually paid to the
Company or a Restricted Subsidiary by such Person during such period, (iii) for
purposes of clause (c) of the covenant "--Certain Covenants--Restricted

determination permitted without any prior governmental approval (that has not
been obtained) or, directly or indirectly, by operation of the terms of its
charter or any agreement, (excluding any such restrictions relating to AC-1 to
which this clause (iii) shall not apply), instrument, judgment, decree, order,
statute, rule or governmental regulation applicable to that Restricted
Subsidiary or its shareholders, except that the Company's equity in the net
income of any such Restricted Subsidiary for such period shall be included in

or indirect obligation to maintain or preserve such Person's financial
condition or to cause such Person to achieve any specified levels of operating
results; and (c) has not guaranteed or otherwise directly or indirectly
provided credit support for any Indebtedness of the Company or any of its
Restricted Subsidiaries. Any such designation by the Board of Directors shall
be evidenced 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 foregoing conditions and was
permitted by the covenant described above under the caption "--Certain
Covenants--Restricted Payments." If, at any time, any Unrestricted Subsidiary
would fail to meet the foregoing requirements as an Unrestricted Subsidiary, it
shall thereafter cease to be an Unrestricted Subsidiary for purposes of the
Indenture and any Indebtedness of such Subsidiary shall be deemed to be
incurred by a Restricted Subsidiary of the Company as of such date (and, if
such Indebtedness is not permitted to be incurred as of such date under the
covenant described under the caption "--Certain Covenants--Incurrence of
Indebtedness and Issuance of Preferred Stock," the Company shall be in default
of such covenant). The Board of Directors of the Company may at any time
designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided
that such designation shall be deemed to be an incurrence of Indebtedness by a
Restricted Subsidiary of the Company of any outstanding Indebtedness of such
Unrestricted Subsidiary and such designation shall only be permitted if (i)
such Indebtedness is permitted under the covenant described under the caption
"--Certain Covenants--Incurrence of Indebtedness and Issuance of Preferred
Stock," calculated on a pro forma basis as if such designation had occurred at
the beginning of the four-quarter reference period, and (ii) no Default or
Event of Default would be in existence following such designation. As of the
Issue Date, all of the Company's Subsidiaries will be Restricted Subsidiaries,
except for the PC-1 Companies, and the AC Subsidiaries may not be designated as
Unrestricted Subsidiaries unless and until the PC-1 Companies are designated as
Restricted Subsidiaries.
 
  "Voting Stock" of any Person as of any date means the Capital Stock of such
Person that is at the time entitled to vote in the election of the Board of
Directors of such Person.
 
  "Weighted Average Life to Maturity" means, when applied to any Indebtedness
at any date, the number of years obtained by dividing (i) the sum of the
products obtained by multiplying (a) the amount of each then
 
                                      129
<PAGE>
 
remaining installment, sinking fund, serial maturity or other required payments
of principal, including payment at final maturity, in respect thereof, by (b)
the number of years (calculated to the nearest one-twelfth) that will elapse
between such date and the making of such payment, by (ii) the then outstanding
principal amount of such Indebtedness.
 
  "Wholly Owned Restricted Subsidiary" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock or other
ownership interests of which (other than directors' qualifying shares) shall at
the time be owned by such Person or by one or more Wholly Owned Restricted
Subsidiaries of such Person and one or more Wholly Owned Restricted
Subsidiaries of such Person.
 
BOOK-ENTRY, DELIVERY AND FORM
 
  All Notes, if and when issued, will be represented by permanent Global Notes
in fully registered from without coupons (the "Global Notes"), which will be
deposited with the Trustee as custodian for DTC and registered in the name of
DTC or of a nominee of DTC.
 
  DTC has advised the Company that it is (i) a limited purpose company
organized under the laws of the State of New York, (ii) a "banking
organization" within the meaning of the New York Banking Law, (iii) a member of
the Federal Reserve System, (iv) a "clearing corporation" within the meaning of
the Uniform Commercial Code, as amended, and (v) a "clearing agency" registered
pursuant to Section 17A of the Exchange Act. DTC was created to hold securities
for its Participants and to facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
charges to the accounts of its Participants, thereby eliminating the need for
physical transfer and delivery of certificates. DTC's Participants include
securities brokers and dealers (including the initial purchasers), banks and
trust companies, clearing corporations and certain other organizations.
Indirect access to DTC's system is also available to other entities such as
banks, brokers, dealers and trust companies (collectively, the "Indirect
Participants") that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly. Investors who are not Participants
may beneficially own securities held by or on behalf of DTC only through
Participants or Indirect Participants.
 
  The Company expects that pursuant to procedures established by DTC (i) upon
issuance of a Global Note, DTC will credit, on its internal system, the
principal amount of Notes of the individual beneficial interests represented by
such Global Note to the respective accounts of persons who have accounts with
such depository and (ii) ownership of beneficial interests in such Global Notes
will be shown on, and the transfer of such ownership will be effected only
though, records maintained by DTC (with respect to interest of Participants)
and the records of Participants and Indirect Participants (with respect to
interests of persons other than Participants).
 
  The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of securities is definitive form.
Accordingly, the ability to transfer interests in the Notes represented by a
Global Note to such persons may be limited. In addition, because DTC can act
only on behalf of its Participants, who in turn act on behalf of persons who
hold interests through Participants, the ability of a person having an interest
in Notes represented by a Global Note to pledge or transfer such interest to
persons or entities that do not participate in DTC's system, or to otherwise
take actions in respect of such interest, may be affected by the lack of a
physical definitive security in respect of such interest.
 
  So long as DTC or its nominee is the registered owner of a Global Note, DTC
or such nominee, as the case may be, will be considered to be the sole owner or
holder of the Notes represented by the Global Note for all purposes under the
Indenture. Except as provided below, owners of beneficial interest in a Global
Note will not be entitled to have Notes represented by such Global Note
registered in their names, will not receive or be entitled to receive physical
delivery of Certificated Notes, and will not be considered the owners or
holders thereof under the Indenture for any purpose, including with respect to
the giving of any direction, instruction or
 
                                      130
<PAGE>
 
approval to the Trustee thereunder. Accordingly, each holder owning a
beneficial interest in a Global Note must rely on the procedures of DTC and, if
such holder is not a Participant or an Indirect Participant, on the procedures
of the Participant through which such holder owns its interest, to exercise any
rights of a holder of Notes under the Indenture or such Global Note. The
Company understands that under existing industry practice, in the event that
the Company requests any action of holders of Notes, or a holder that is an
owner of a beneficial interest in a Global Note desires to take any action that
DTC, as the holder of such Global Note, is entitled to take, DTC would
authorize the Participants to take such action and the Participants would
authorize holders owning through such Participants to take such action or would
otherwise act upon the instruction of such holders. Neither the Company nor the
Trustee will have any responsibility or liability for any aspect of the records
relating to, or payments made on account of, Notes by DTC, or for maintaining,
supervising or reviewing any records of DTC relating to such Notes.
 
  Payments with respect to the principal of, and premium, if any, and interest
on, any Notes represented by a Global Note registered in the name of DTC or its
nominee on the applicable record date will be payable by the Trustee to or at
the direction of DTC or its nominee in its capacity as the registered holder of
the Global Note representing such Notes under the Indenture. Under the terms of
the Indenture, the Company and the Trustee may treat the persons in whose names
the Notes, including the Global Notes, are registered as the owners thereof for
the purpose of receiving payment thereon and for any and all other purposes
whatsoever. Accordingly, neither the Company nor the Trustee has or will have
any responsibility or liability for the payment of such amounts to owners of
beneficial interests in a Global Note (including principal, premium, if any,
and interest). Payments by the Participants and the Indirect Participants to
the owners of beneficial interests in a Global Note will be governed by
standing instructions and customary industry practice and will be the
responsibility of the Participants or the Indirect Participants and DTC.
 
  Transfers between Participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds. Transfers between
participants in Euroclear or Cedel will be effected in the ordinary way in
accordance with their respective rules and operating procedures.
 
  Cross-market transfers between the Participants in DTC, on the one hand, and
Euroclear or Cedel participants, on the other hand, will be effected through
DTC in accordance with DTC's rules on behalf of Euroclear or Cedel, as the case
may be, by its respective depositary; however, such cross-market transactions
will require delivery of instructions to Euroclear or Cedel, as the case may
be, by the counterparty in such system in accordance with the rules and
procedures and within the established deadlines (Brussels time) of such system.
Euroclear or Cedel, as the case may be, will, if the transaction meets its
settlement requirements, deliver instructions to its respective depositary to
take action to effect final settlement on its behalf by delivering or receiving
interests in the relevant Global Notes in DTC, and making or receiving payment
in accordance with normal procedures for same-day funds settlement applicable
to DTC. Euroclear participants and Cedel participants may not deliver
instructions directly to the depositaries for Euroclear or Cedel.
 
  Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in a Global Note from a Participant in
DTC will be credited, and any such crediting will be reported to the relevant
Euroclear or Cedel participant, during the securities settlement processing day
(which must be a business day for Euroclear and Cedel) immediately following
the settlement date of DTC. Cash received in
Euroclear or Cedel as a result of sales of interest in a Global Note by or
through a Euroclear or Cedel participant to a Participant in DTC will be
received for value on the settlement date of DTC but will be available in the
relevant Euroclear or Cedel cash account only as of the business day for
Euroclear or Cedel following DTC's settlement date.
 
  Although DTC, Euroclear and Cedel have agreed to the foregoing procedures to
facilitate transfers of interests in the Global Notes among participants in
DTC, Euroclear and Cedel, 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 will have any responsibility for
the performance by DTC, Euroclear or
 
                                      131
<PAGE>
 
Cedel or their respective participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.
 
  DTC management is aware that some Systems 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 the Industry 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:
(i) impress upon them the importance of such services being Year 2000
compliant; and (ii) 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.
 
CERTIFICATED NOTES
 
  If (i) the Company notifies the trustee in writing that DTC is no longer
willing or able to act as a depositary or DTC ceases to be registered as a
clearing agency under the Exchange Act and a successor depositary is not
appointed within 90 days of such notice or cessation, (ii) the Company, at its
option, notifies the trustee in writing that it elects to cause the issuance of
Notes in definitive form under the Indenture or (iii) upon the occurrence of
certain other events as provided in the Indenture, then, upon surrender by DTC
of the Global Notes, certificated Notes will be issued to each person that DTC
identifies as the beneficial owner of the Notes represented by the Global
Notes. Upon any such issuance, the trustee is required to register such
certificated Notes in the name of such person or persons (or the nominee of any
thereof) and cause the same to be delivered thereto.
 
  Neither the Company nor the trustee shall be liable for any delay by DTC or
any Participant or Indirect Participant in identifying the beneficial owners of
the related Notes and each such person may conclusively rely on, and shall be
protected in relying on, instructions from DTC for all purposes (including with
respect to the registration and delivery, and the respective principal amounts,
of the Notes to be issued).
 
EXCHANGE OFFER; REGISTRATION RIGHTS
 
  The Company and the Initial Purchasers entered into the Registration Rights
Agreement pursuant to which the Company agreed, for the benefit of the holders
of the Old Preferred Stock or the Old Exchange Notes, as applicable, that the
Company will, at its cost:
 
  .  to file the registration statement of which this prospectus is a part
     with the Securities and Exchange Commission under the Securities Act of
     1933, to exchange the Old Preferred Stock for the Exchange Preferred
     Stock by March 2, 1999,
 
  .  to use its reasonable best efforts to cause the registration statement
     to be declared effective under the Securities Act by May 28, 1999, and
 
  .  to keep the Exchange Offer open for the minimum period required by
     applicable federal law and state securities laws, provided, however that
     it shall remain open for no less than 20 Business Days.
 
                                      132
<PAGE>
 
  For each share of Preferred Stock or each Exchange Note surrendered to the
Company and accepted for exchange pursuant to the Exchange Offer, the holder of
such security will receive a registered security having a liquidation
preference or principal amount equal to that of the surrendered restricted
security.
 
  If (i) the Exchange Offer is not permitted by applicable law or Securities
and Exchange Commission policy or (ii) if any Holder shall notify the Company
within 20 Business Days following the consummation of the Exchange Offer that
(A) such holder was prohibited by law or Securities and Exchange Commission
policy from participating in the Exchange Offer or (B) such holder may not
resell the securities acquired by it in the Exchange Offer to the public
without delivering a prospectus and the prospectus contained in the exchange
offer registration statement is not appropriate or available for such resales
by such holders or (C) such holder is a broker-dealer and holds Securities
acquired directly from the Company or any of its affiliates, then the Company
will, at its cost, (a) use its reasonable best efforts to cause to be filed a
shelf registration statement (the "Shelf Registration Statement") covering
resales of the restricted securities, (b) use its reasonable best efforts to
cause the Shelf Registration Statement to be declared effective under the
Securities Act of 1933 and (c) use its reasonable best efforts to keep the
Shelf Registration Statement effective until two years after its effective date
or such shorter period ending when all resales of the securities covered by
such Shelf Registration Statement have been made. A holder selling such
securities pursuant to the Shelf Registration Statement generally would be
required to be named as a selling security holder in the related prospectus and
to deliver a prospectus to purchasers, will be subject to certain of 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
which are applicable to such holder (including certain indemnification
obligations).
 
  If (a) the Company fails to file any of the registration statements required
by the Registration Rights Agreement on or before the date specified for such
filing, (b) any of such registration statements is not declared effective by
the Commission on or prior to the date specified for such effectiveness, or (c)
the Company fails to consummate the Exchange Offer within 210 days of the
Closing Date with respect to the exchange offer registration statement, or (d)
any registration statement required by the Registration Rights Agreement is
declared effective but thereafter ceases to be effective or usable in
connection with its intended purpose (each such event referred to in clause (a)
through (d) above a "Registration Default"), then the Company will pay to each
holder of the securities affected thereby special interest which will
accumulate or accrue and be payable semi-annually thereon (in addition to the
stated dividends or stated interest) from and including the date such
Registration Default occurs to, but excluding the date on which the applicable
registration statement is filed or is declared effective, the Exchange Offer is
consummated, or the applicable registration statement is again declared
effective or made usable. During the time that special dividends or special
interest is accumulating or accruing continuously, the rate of such special
dividends or special interest shall be 0.50% per annum during the first 90-day
period and shall increase by 0.25% per annum for each subsequent 90-day period,
but in no event shall such rate exceed 1.0% per annum in the aggregate
regardless of the number of Registration Defaults. If, after the cure of all
Registration Defaults then in effect, there is a subsequent Registration
Default, the rate of special dividends or special interest for such subsequent
Registration Default shall initially be 0.50% regardless of the special
dividends or special interest rate in effect with respect to any prior
Registration Default at the time of the cure of such Registration Default.
 
  The summary herein of certain provisions of the Registration Rights Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Registration Rights
Agreement, which is an exhibit to the registration statement of which this
prospectus is a part.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
9 5/8% SENIOR NOTES
 
  On May 18, 1998, we consummated the Senior Notes Offering pursuant to which
we issued an aggregate of $800 million in principal amount of 9 5/8% Senior
Notes. The Senior Notes are guaranteed by GCL and certain of our subsidiaries.
The Senior Notes mature on May 15, 2008. Interest on the Senior Notes is
payable in U.S. dollars on May 15 and November 15 of each year. The Senior
Notes were issued under an indenture with the United States Trust Company of
New York, dated as of May 18, 1998. This indenture restricts our ability and
the ability of certain of our subsidiaries to: borrow money, pay dividends on
stock or purchase stock, make investments, use assets as security in other
transactions and sell certain assets or merge with or into other companies. See
"Summary--Financing Plan."
 
AC-1 CREDIT FACILITY
 
  ACL is the borrower under the $482.0 million senior secured AC-1 Credit
Facility, comprised of a $472.0 million term loan facility and a $10.0 million
working capital facility, with certain commercial lending institutions and CIBC
and Deutsche Bank AG, New York Branch, an affiliate of Deutsche Bank Securities
Inc., as lead agents for the lenders. The AC-1 Credit Facility is secured by
pledges of the stock of ACL and its subsidiaries (and other entities holding
landing licenses or AC-1 assets) and security interests in the assets and
revenues of ACL and its subsidiaries and is being used to provide financing for
a portion of AC-1. A portion of the AC-1 Credit Facility is available only to
pay interest on the loans prior to the AC-1 RFS date, and a portion is
available to issue letters of credit to the contractor of AC-1. The loans under
the AC-1 Credit Facility will amortize in eight semi-annual installments,
commencing on the first initial principal payment date (which shall be May 31
or November 30) to occur more than two months after the commercial operation
date (anticipated to occur in February 1999), with 15% of the principal amount
to be amortized in the first year, 25% in the second year, 30% in the third
year and 30% in the fourth year. Borrowings bear interest at an adjustable rate
based on the adjusted base rate or LIBOR plus an applicable margin. The
facility also requires mandatory prepayments to be made from, among other
things, 50% of excess cash flow, 50% of net cash proceeds of any equity
offering of ACL and 100% of net cash proceeds of any permitted debt offerings
of ACL or its immediate parent, permitted asset sales or insurance proceeds. As
of September 30, 1998, a total of $365.1 million in indebtedness (to which the
Securities would be effectively subordinated) was outstanding under the AC-1
Credit Facility.
 
  The AC-1 Credit Facility contains covenants that, among other things,
restrict ACL's use of the term loan proceeds to the financing of AC-1 and the
payment of fees and expenses directly thereto and the use of the working
capital facility proceeds to AC-1 costs and for working capital purposes and
limit ACL's ability to make certain dividends, distributions or investments and
mergers. The facility generally only permits dividends or distributions with
respect to a portion of ACL's excess cash flow, but severely restricts the
payment of other dividends or distributions to GCL. The AC-1 Credit Facility
contains certain financial covenants relating to minimum sales of capacity on
AC-1 and ratio of EBITDA to interest expense, the failure to comply with which
would cause all excess cash flow to be applied to the lenders under the AC-1
Credit Facility for such period. The AC-1 Credit Facility contains certain
events of default including, among other things, failure to pay amounts when
due, failure to comply with covenants and insolvency. An event of default shall
also occur upon the occurrence of certain failures in connection with AC-1.
Upon the occurrence of an event of default, the AC-1 Credit Facility permits
the lenders to declare all outstanding borrowings to be immediately due and
payable and to proceed against the collateral. In addition, the AC-1 Credit
Facility prescribes the order by which proceeds from the sale of AC-1 capacity
shall be applied, both prior to and after the commencement of commercial
operations, and requires ACL to maintain certain reserve accounts. As a result
of the foregoing, the ability of ACL to use and distribute revenue is severely
restricted so long as the AC-1 Credit Facility remains in existence.
 
                                      134
<PAGE>
 
PC-1 CREDIT FACILITY
 
  PCL is the borrower under the $850.0 million senior secured PC-1 Credit
Facility, comprised of a $840.0 million term loan and a $10.0 million working
capital facility, with certain commercial lending institutions and Deutsche
Bank AG, New York Branch, an affiliate of Deutsche Bank Securities, CIBC Inc.
and Goldman, Sachs Credit Partners L.P., as Lead Agents for the lenders. The
PC-1 Credit Facility is secured by pledges of the stock of PCL and its
subsidiaries and security interests in certain of the assets and revenues of
PCL and its subsidiaries and is being used to provide financing for a portion
of PC-1. The subsidiaries of PCL also guaranteed PCL's obligations under the
PC-1 Credit Facility. A portion of the PC-1 Credit Facility is available only
to pay interest on the loans prior to the PC-1 RFS date. The term loans under
the PC-1 Credit Facility will amortize over ten semi-annual installments,
scheduled to commence approximately 165 days after the commercial operation
date. Borrowings bear interest at an adjustable rate based on the adjusted base
rate or LIBOR plus an applicable margin. The facility also requires mandatory
prepayments to be made from, among other things, 50% of excess cash flow, 50%
of the net cash proceeds of any equity offering of PCL and 100% of net cash
proceeds of any permitted debt offering of PCL, permitted asset sale and
insurance proceeds. As of September 30, 1998, a total of $200 million was
outstanding.
 
  The PC-1 Credit Facility contains covenants that, among other things,
restrict PCL's ability to incur indebtedness, make investments, guarantees or
acquisitions and make dividends or distributions. The facility generally only
permits dividends or distributions by PCL out of a portion of excess cash flow,
and securely restricts the payment of other dividends or distributions. The PC-
1 Credit Facility contains certain financial covenants relating to minimum
sales of capacity on PC-1 and the ratio of system revenues to interest expense,
the failure to comply with which would cause all excess cash flow to be applied
to the lenders under the PC-1 Credit Facility. The PC-1 Credit Facility
contains events of default including, among other things, failure to pay
amounts when due, failure to comply with certain covenants and insolvency. An
event of default shall also occur upon the occurrence of certain failures in
connection with PC-1. Upon the occurrence of an event of default, the PC-1
Credit Facility permits the lenders to (1) declare the loans then outstanding
to be immediately due and payable, (2) demand that any equity commitments not
theretofore funded to be immediately funded, and (3) proceed against the
collateral. In addition, the PC-1 Credit Facility prescribes the order by which
proceeds from the sale of PC-1 capacity shall be applied, both prior to and
after the commencement of commercial operation, and requires PCL to maintain
certain reserve warrants. As a result of the foregoing, the ability of PCL to
use and distribute revenue is severely restricted so long as the PC-1 Credit
Facility remains in existence.
 
MAC CREDIT FACILITY
 
  MACL is the borrower under the $260.0 million senior secured MAC Credit
Facility, comprised of a $220.0 million term loan to fund the construction of
MAC, a $30.0 million term loan to fund future upgrades of MAC and a $10.0
million working capital facility, with certain commercial lending institutions
and CIBC Inc. and Deutsche Bank AG, New York Branch, an affiliate of Deutsche
Bank Securities Inc., as lead agents for the lenders. The MAC Credit Facility
is secured by pledges of the stock of MACL and its subsidiaries and security
interests in certain of the assets and revenues of MACL and its subsidiaries
and is being used to provide financing for a portion of MAC. A portion of the
MAC Credit Facility is available only to pay interest on the loans prior to the
MAC RFS date. The term loans under the MAC Credit Facility will amortize over
ten semi-annual installments, scheduled to commence approximately in August
2000. Borrowings bear interest at an adjustable rate based on the adjusted base
rate or LIBOR plus an applicable margin. The facility also requires mandatory
prepayments to be made from, among other things, 50% of excess cash flow, 50%
of net cash proceeds of any equity offering of MACL and 100% of net cash
proceeds of any permitted debt offerings of MACL, permitted asset sale or
insurance proceeds.
 
  The MAC Credit Facility contains covenants that, among other things, restrict
MACL's ability, and any subsidiary's ability, to incur indebtedness, make
investments, loans, advances, guarantees and acquisitions, and make dividends
and distributions. The facility generally only permits dividends or
distributions with respect to a portion of MACL's excess cash flow, and
securely restricts the payments of other dividends and payments.
 
                                      135
<PAGE>
 
  The MAC Credit Facility contains certain financial covenants relating to
minimum sales of capacity on MAC, minimum interest coverage ratio and minimum
remaining asset value to debt, the failure to comply with which would cause all
excess cash flow to be applied to the lenders under the MAC Credit Facility.
The MAC Credit Facility contains events of default including, among other
things, failure to pay amounts when due, failure to comply with covenants and
insolvency. An event of default shall also occur upon the occurrence of certain
failures in connection with MAC. Upon the occurrence of an event of default,
the MAC Credit Facility permits the lenders to (1) declare the loans then
outstanding to be immediately due and payable and (2) to proceed against the
collateral. In addition, the MAC Credit Facility prescribes the order by which
proceeds from the sale of MAC capacity shall be applied, both prior to and
after the commencement of commercial operations, and requires MACL to maintain
certain reserve accounts. As a result of the foregoing, the ability of MACL to
use and distribute revenue is severely restricted so long as the MAC Credit
Facility remains in existence.

                               TAX CONSIDERATIONS
 
TAXATION OF THE COMPANY
 
  The Company believes that a significant portion of the income derived from
its subsea systems will not be subject to tax in Bermuda, which currently has
no corporate income tax, or other countries in which the Issuer or its
affiliates conduct activities or in which customers of the Company are located,
including the United States. However, this belief is based upon the anticipated
nature and conduct of the business of the Company, which may change, and upon
the Company's understanding of its position under the tax laws of the various
countries in which the Company has assets or conducts 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 the Company to pay tax or to
make payments in lieu of tax cannot be determined in advance. In addition, the
operations of and payments due to the Company may be affected by changes in
taxation, including retroactive tax claims or assessments of withholding on
amounts payable to the Company or other taxes assessed at the source, in excess
of the taxation anticipated by the Company based on business contacts and
practices of the Company and the current tax regimes. There can be no assurance
that these factors will not have a material adverse effect on the Company.
 
 United States Federal Income Tax Considerations
 
  The Issuer and its non-United States subsidiaries will be subject to United
States federal income tax at regular corporate rates (and to United States
branch profits tax) on their income that is effectively connected with the
conduct of a trade or business within the United States, and will be required
to file federal income tax returns reflecting that income. The Company intends
to conduct its operations so as to reduce the amount of its effectively
connected income. However, no assurance can be given that the Internal Revenue
Service ("IRS") will agree with the positions taken by the Company in this
regard. Moreover, the United States subsidiaries of the Issuer 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 the Issuer or its foreign
subsidiaries generally will be subject to United States withholding tax.
 
 Bermuda Tax Considerations
 
  Under current Bermuda law, the Company is not subject to tax on income or
capital gains. Furthermore, the Company has obtained from the Minister of
Finance of Bermuda 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, income, 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 the Company or to any of
its operations, or the Preferred Stock or Exchange Notes of the Company, until
March 28, 2016. This undertaking does not, however, prevent the imposition of
property taxes on any company owning real property or leasehold interests in
Bermuda.
 
TAXATION OF HOLDERS OF PREFERRED STOCK AND EXCHANGE NOTES
 
 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 Preferred
Stock or the Exchange Notes or on any payments thereunder. See "Taxation of the
Issuer--Bermuda Tax Considerations" for a description of the undertaking on
taxes obtained by the Company from the Minister of Finance of Bermuda.
 
 United States Federal Income Tax Considerations
 
  The following summary describes certain United States federal income tax
consequences of the purchase, ownership and disposition of Preferred Stock and
Exchange Notes by initial holders who acquired the Preferred Stock pursuant to
the offering of the Old Preferred Stock. Except where noted, this summary
assumes that
 
                                      137
<PAGE>
 
investors will hold their Preferred Stock and Exchange Notes as capital assets
and does not discuss special situations, such as those of dealers in securities
or currencies, financial institutions, tax-exempt entities, life insurance
companies, persons holding Preferred Stock and Exchange Notes as a part of a
hedging, short-sale, "integrated" or conversion transaction or a straddle or
holders of Preferred Stock or Exchange Notes whose "functional currency" is not
the United States dollar all of whom may be subject to rules that differ
significantly from those summarized below. In addition, the summary generally
does not address the tax consequences to United States Holders (as defined
below) that own (or are deemed for United States federal income tax purposes to
own, pursuant to complex attribution and constructive ownership rules) 10% or
more of the voting stock of the Issuer or any of its non-United States
subsidiaries ("10% Shareholders"). 10% Shareholders are advised to consult
their own tax advisors regarding the federal, state, local and foreign income
and other tax considerations incident to an investment in the Preferred Stock
and Exchange Notes.
 
  The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), and regulations, rulings and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified so as to result in United States federal income
tax consequences different from those discussed below.
 
  As used herein, a "United States Holder" of Preferred Stock or Exchange Notes
means a holder that is (i) a citizen or resident of the United States, (ii) a
corporation or partnership created or organized in or under the laws of the
United States or any political subdivision thereof, (iii) an estate the income
of which is subject to United States federal income taxation regardless of its
source or (iv) a trust which is subject to the supervision of a court within
the United States and the control of one or more United States persons as
described in section 7701(a)(30) of the Code. A Non-United States Holder means
a holder other than a United States Holder.
 
  PERSONS CONSIDERING THE PURCHASE, OWNERSHIP OR DISPOSITION OF PREFERRED STOCK
OR EXCHANGE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED
STATES FEDERAL, STATE AND LOCAL INCOME AND OTHER TAX CONSEQUENCES IN LIGHT OF
THEIR PARTICULAR CIRCUMSTANCES AS WELL AS ANY CONSEQUENCES ARISING UNDER THE
LAWS OF ANY OTHER TAXING JURISDICTION.
 
TAX CONSEQUENCES OF THE EXCHANGE OFFER
 
  The exchange of Old Preferred Stock for Exchange Preferred Stock in the
Exchange Offer will not constitute a taxable event to holders. Consequently, no
gain or loss will be recognized by a holder upon receipt of the Exchange
Preferred Stock. The holding period of the Exchange Preferred Stock will
include the holding period the Old Preferred Stock and the basis of the
Exchange Preferred Stock will be the same as the basis of the Old Preferred
Stock immediately before the exchange.
 
  In any event, persons considering the exchange of Old Preferred Stock for
Exchange Preferred Stock should consult their own tax advisors concerning the
United States federal income tax consequences in light of their particular
situations as well as any consequences arising under the laws of any other
taxing jurisdiction.
 
UNITED STATES HOLDERS
 
CLASSIFICATION OF PREFERRED STOCK AND EXCHANGE NOTES
 
  Although the characterization of an instrument as debt or equity is a factual
determination that cannot be predicted with certainty, the Issuer intends to
treat the Preferred Stock as stock and the Exchange Notes as debt for United
States federal income tax purposes. The remainder of this discussion assumes
that such treatment will be respected, but no opinion is either expressed or
implied on this issue. Any change in these assumptions would alter the tax
consequences described below.
 
 
                                      138
<PAGE>
 
PREFERRED STOCK
 
 Dividends
 
  Subject to the PFIC rules described below, distributions on the Preferred
Stock will constitute dividend income for United States federal income tax
purposes, subject to tax as ordinary income, to the extent paid from current or
accumulated earnings and profits of the Issuer (as determined under United
States federal income tax principles) ("earnings and profits"). Such dividends
will not be eligible for the dividends received deduction allowed to
corporations under the Code. Dividends "paid in kind" through the issuance of
additional Preferred Stock will be treated as distributions in an amount equal
to the fair market value of such additional Preferred Stock as of the date of
distribution. Such amount will also be the initial issue price and tax basis of
the newly distributed Preferred Stock for United States federal income tax
purposes. The holding period for such newly distributed Preferred Stock will
commence with its distribution, and will not include the United States Holder's
holding period for outstanding shares of Preferred Stock with respect to which
such newly distributed Preferred Stock was distributed.
 
                                      139
<PAGE>
 
  The Issuer believes that it currently has no current or accumulated earnings
and profits. The existence of current and accumulated earnings and profits in
subsequent years will depend on future levels of profits and losses which the
Issuer cannot accurately predict at this time. To the extent that the amount of
any distribution on the Preferred Stock, exceeds the Issuer's current and
accumulated earnings and profits, the distribution will first be treated as a
tax-free return of capital, causing a reduction in the adjusted basis of the
Preferred Stock (thereby increasing the amount of gain, or decreasing the
amount of loss, to be recognized by the United States Holder on a subsequent
disposition of the Preferred Stock), and the balance in excess of the adjusted
basis will be subject to tax as capital gain.
 
  For so long as the Issuer is a "United States-owned foreign corporation,"
distributions with respect to the Preferred Stock that are taxable as dividends
generally will be treated for United States foreign tax credit purposes as (i)
foreign source "passive income" (or, in the case of certain United States
Holders, foreign source "financial services income") and (ii) United States
source income, in proportion to the earnings and profits of the Issuer in the
year of such distribution allocable to foreign and United States sources,
respectively. For this purpose, the Issuer will be treated as a United States-
owned foreign corporation so long as stock representing 50% or more of the
voting power or value of the Issuer is owned, directly or indirectly, by United
States Holders. The Issuer believes that it currently is characterized as a
United States-owned foreign corporation for United States federal income tax
purposes.
 
 Redemption Premium
 
  Under Section 305(c) of the Code and the applicable regulations thereunder,
if in certain circumstances the redemption price of the Preferred Stock exceeds
its issue price by more than a de minimis amount, the difference ("redemption
premium") will be taxable as a constructive distribution of additional
Preferred Stock to the United States Holder under a constant interest rate
method similar to that described below for accruing original issue discount
("OID") (see "Exchange Notes--Original Issue Discount"). Because the Preferred
Stock provides for optional rights of redemption by the Issuer at prices in
excess of the issue price, stockholders could be required to recognize such
excess if, based on all of the facts and circumstances, the optional
redemptions are more likely than not to occur. Applicable regulations provide a
"safe harbor" under which a right to redeem will not be treated as more likely
than not to occur if (i) the Issuer and the United States Holder are not
related within the meaning of the regulations; (ii) there are no plans,
arrangements, or agreements that effectively require or are intended to compel
the Issuer to redeem the stock (disregarding, for this purpose, a separate
mandatory redemption), and (iii) exercise of the right to redeem would not
reduce the yield of the stock, as determined under the regulations. Regardless
of whether the optional redemptions are more likely than not to occur,
constructive dividend treatment will not result if the redemption premium does
not exceed a de minimis amount or is in the nature of a penalty for premature
redemption. The Issuer intends to take the position that the existence of the
Issuer's optional redemption rights does not result in a constructive
distribution to United States Holders.
 
  Any additional shares of Preferred Stock distributed by the Issuer in lieu of
cash dividend payments on the Preferred Stock will bear redemption premium if
the issue price of such shares (i.e., the fair market value of such shares on
the date of issuance) is less than their redemption price. This may give rise
to constructive distributions as described above. If such shares bear
redemption premium, such shares generally will have different tax
characteristics than other shares of Preferred Stock. This difference in tax
characteristics could adversely affect the liquidity of the shares.
 
 Disposition of Preferred Stock
 
  A United States Holder's adjusted tax basis in the Preferred Stock will, in
general, be the United States Holder's initial tax basis of such Preferred
Stock increased by any redemption premium previously included in income by the
United States Holder, and reduced by any previous distributions that are not
characterized as dividends. Subject to the PFIC rules described below, upon the
sale or other disposition of Preferred Stock (other than by redemption,
discussed below) a United States Holder will generally recognize capital gain
or loss
 
                                      140
<PAGE>
 
equal to the difference between the amount realized upon the disposition and
the adjusted tax basis of the Preferred Stock. Such gain or loss will be
capital gain or loss and will be long-term capital gain or loss if at the time
of sale, exchange, redemption or other disposition the Preferred Stock has been
held for more than one year. Net capital gain of individuals derived in respect
of capital assets held for more than one year are eligible for reduced rates of
taxation. The deductibility of capital losses is subject to limitations. Any
gain recognized by a United States Holder generally will be treated as United
States source income. It is presently unclear whether any loss realized by a
United States Holder will be treated as United States or foreign source.
 
  A redemption of the Preferred Stock by the Issuer would be treated, under
Section 302 of the Code, either as a sale or exchange giving rise to capital
gain or loss or as described below as a dividend. In the case of a redemption
of Preferred Stock for Exchange Notes, the amount realized on the exchange
would be equal to the "issue price" of the Exchange Note plus any cash received
on the exchange. The issue price of an Exchange Note would be equal to (i) its
fair market value as of the exchange date if the Exchange Notes are traded on
an established securities market on or at any time during a specified period or
(ii) the fair market value at the exchange date of the Preferred Stock if such
Preferred Stock is traded on an established securities market during a
specified period but the Exchange Notes are not. If neither the Preferred Stock
nor the Exchange Notes are so traded, the issue price of the Exchange Notes
would be determined under Section 1274 of the Code, in which case the issue
price would be the stated principal amount of the Exchange Notes provided that
the yield on the Exchange Notes is equal to or greater than the "applicable
federal rate" in effect at the time the Exchange Notes are issued. If the yield
on the Exchange Notes is less than such applicable federal rate, its issue
price under section 1274 of the Code would be equal to the present value as of
the issue date of all payments to be made on the Exchange Notes discounted at
the applicable federal rate. It cannot be determined at the present time
whether the Preferred Stock or the Exchange Notes will be, at the relevant
time, traded on an established securities market or whether the yield on the
Exchange Notes will equal or exceed the applicable federal rate, as discussed
above.
 
  If a redemption of shares of the Preferred Stock for cash or an exchange of
the Preferred Stock for Exchange Notes is treated as a dividend with respect to
a particular exchanging United States Holder under Section 302 of the Code,
such United States Holder (i) will not recognize any loss on the exchange, (ii)
will recognize dividend income (rather than capital gain) in an amount equal to
the issue price of the Exchange Notes received, without regard to the United
States Holder's basis in the shares of Preferred Stock surrendered in the
exchange, to the extent of its proportionate share of the Issuer's current or
accumulated earnings and profits and (iii) the holding period for the Exchange
Notes will begin on the day after the day on which the Exchange Notes are
acquired by the exchanging United States Holder. Pursuant to Section 302 of the
Code, the redemption or exchange will not be treated as a dividend provided
that, after giving effect to the constructive ownership rules of Section 318 of
the Code, the redemption or exchange (i) represents a "complete termination" of
the exchanging United States Holder's stock interest in the Issuer, (ii) is
"substantially disproportionate" with respect to the exchanging United States
Holder or (iii) is "not essentially equivalent to a dividend" with respect to
the exchanging United States Holder, all within the meaning of Section 302(b)
of the Code. An exchange will be "not essentially equivalent to a dividend" as
to a particular United States Holder if it results in a "meaningful reduction"
in such United States Holder's interest in the Issuer (after application of the
constructive ownership rules of Section 318 of the Code). In general, there are
no fixed rules for determining whether a "meaningful reduction" has occurred.
Each United States Holder should consult its own tax advisor as to its ability
in light of its own particular circumstances to satisfy any of the foregoing
tests.
 
  Depending upon a United States Holder's particular circumstances, the tax
consequences of holding Exchange Notes may be less advantageous than the tax
consequences of holding Preferred
Stock, for example, as discussed at "Exchange Notes--Original Issue Discount,"
Exchange Notes may be issued with OID.

 Passive Foreign Investment Company
 
  The Issuer believes that it is not a PFIC and does not expect to become a
PFIC in the future for United States federal income tax purposes, although
there can be no assurance in this regard. This conclusion is a factual
determination made annually and thus is subject to change. In addition, it is
based, in part, on interpretations of existing law that the Issuer believes
are reasonable, but which have not been approved by any taxing authority.
 
  In general, the Issuer will be a PFIC with respect to a United States Holder
if, for any taxable year in which the United States Holder held Preferred
Stock, either (i) at least 75% of the gross income of the Issuer for the
taxable year is passive income or (ii) at least 50% of the value (determined
on the basis of a quarterly average) of the Issuer's assets is attributable to
assets that produce or are held for the production of passive income. For this
purpose, passive income generally includes dividends, interest, royalties,
rents (other than rents and royalties derived in the active conduct of a trade
or business and not derived from a related person), annuities and gains from
assets that produce passive income. If the Issuer owns (directly or
indirectly) at least 25% by value of the stock of another corporation, the
Issuer will be treated for purposes of the PFIC tests as owning its
proportionate share of the assets of the other corporation, and as receiving
directly its proportionate share of the other corporation's income. If the
Issuer is classified as a PFIC in any year with respect to which a United
States person is a shareholder, the Issuer generally will continue to be
treated as a PFIC with respect to such shareholder in all succeeding years,
regardless of whether it continues to meet the income or asset test described
above, subject to certain possible shareholder elections that may apply in
certain circumstances.
 
  If the Issuer is treated as a PFIC, unless a United States Holder makes a
"QEF election" or a "mark to market election," each as described below:
 
  1. Distributions made by the Issuer during a taxable year to a United
     States Holder with respect to Preferred Stock that are "excess
     distributions" (defined generally as the excess of the amount received
     with respect to the Preferred Stock in any taxable year over 125% of the
     average received in the shorter of either the three previous years or
     the United States Holder's holding period before the taxable year) must
     be allocated ratably to each day of the United States Holder's holding
     period. The amounts allocated to the current taxable year and to taxable
     years prior to the first year in which the Issuer was classified as a
     PFIC are included as ordinary income in the United States Holder's gross
     income for that current year. The amount allocated to each other prior
     taxable year is taxed as ordinary income at the highest rate in effect
     for the United States Holder in that prior year and the tax is subject
     to an interest charge at the rate applicable to deficiencies in income
     taxes.
 
  2. The entire amount of any gain realized upon the sale or other
     disposition (including for these purposes a pledge) of Preferred Stock
     will be treated as an excess distribution made in the year of sale or
     other disposition and as a consequence will be treated as ordinary
     income and, to the extent allocated to years prior to the year of sale
     or disposition, will be subject to the interest charge described above.
     In addition, United States Holders who acquire their Preferred Stock
     from decedents generally will not receive a "stepped-up" basis in such
     Preferred Stock. Instead, such United States Holder will have a tax
     basis equal to the lower of the fair market value of such Preferred
     Stock or the decedent's basis.
 
  The special PFIC tax rules described above will not apply to a United States
Holder if the United States Holder elects to have the Issuer treated as a
"qualified electing fund" (a "QEF election") and the Issuer provides certain
information to United States Holders. If the Issuer is treated as a PFIC, it
intends to notify United States Holders and to provide to United States
Holders such information as may be required to make such QEF election
effective.
 
  A United States Holder that makes a QEF election will be taxable currently
on its pro rata share of the Issuer's ordinary earnings and net capital gain
(at ordinary income and capital gain rates, respectively) for each taxable
year of the Issuer during which it is treated as a PFIC, regardless of whether
or not distributions were received. The United States Holder's basis in the
Preferred Stock will be increased to reflect taxed but
 
                                      142
<PAGE>
 
undistributed income. Distributions of income that had previously been taxed
will result in a corresponding reduction of basis in the Preferred Stock and
will not be taxed again as a distribution to the United States Holder.
 
  Alternatively, a United States Holder of stock in a PFIC that is treated as
"marketable stock" may make a mark to market election. A United States Holder
that makes such an election will not be subject to the PFIC rules described
above. Instead, in general, an electing United States Holder will include in
income each year as ordinary income the excess, if any, of the fair market
value of such stock at the end of the taxable year over its adjusted basis and
will be permitted an ordinary loss in respect of the excess, if any, of the
adjusted basis of such stock over its fair market value at the end of the
taxable year (but only to the extent of the net amount previously included in
income as a result of the mark to market election). The electing United States
Holder's basis in the stock will be adjusted to reflect any such income or loss
amounts. Any gain or loss on the sale of the Preferred Stock will be ordinary
income or loss (except that such loss will be ordinary loss only to the extent
of the previously included net mark to market gain.) The mark to market
election is only available with respect to stock that is regularly traded on
certain United States exchanges and other exchanges designated by the United
States Treasury. The Company does not expect that the Preferred Stock will meet
such requirements.
 
  A United States Holder who owns Preferred Stock during any year that the
Issuer is a PFIC must file IRS Form 8621. United States Holders are urged to
consult their tax advisors concerning the United States federal income tax
consequences of holding Preferred Stock of the Issuer if it is considered a
PFIC, including the advisability and availability of making any of the
foregoing elections.
 
 Foreign Personal Holding Company
 
  If the Issuer or one of its non-United States subsidiaries were classified as
an FPHC, all United States Holders (including certain indirect holders),
regardless of their percentage ownership, would be required to include in
income, as a dividend, their pro rata share of the Issuer's (or its relevant
non-United States subsidiary's) undistributed FPHC income (generally, taxable
income with certain adjustments) if they were holders on the last day of the
Issuer's taxable year (or if earlier, the last day on which the Issuer
satisfied the shareholder test). In addition, if the Issuer were classified as
an FPHC, United States Holders who acquire their Preferred Stock from decedents
would not receive a "stepped-up" basis in such Preferred Stock. Instead, such
United States Holders would have a tax basis equal to the lower of the fair
market value of such Preferred Stock or the decedent's basis.
 
  A foreign corporation will be classified as an FPHC if (i) at any time during
the corporation's taxable year, five or fewer individuals, who are United
States citizens or residents, directly or indirectly own more than 50% of the
corporation's stock (by either voting power or value) (the "shareholder test")
and (ii) the corporation receives at least 60% of its gross income (50% after
the initial year of qualification), as adjusted, for the taxable year from
certain passive sources (the "income test"). It is possible that the Issuer and
its subsidiaries could meet the shareholder test in a given taxable year. It is
also possible that the Issuer or one of its non-United States subsidiaries
would meet the income test in a given year and would be treated as an FPHC. The
Company intends to manage its affairs so as to attempt to avoid or minimize
having income imputed to its United States Holders under these rules, to the
extent such management of its affairs is consistent with its business goals,
although there can be no assurance in this regard.
 
 Personal Holding Company
 
  A corporation classified as a PHC is subject to a 39.6% tax on its
undistributed PHC income. Foreign corporations (such as the Issuer) determine
their liability for PHC tax by considering only (i) gross income derived from
United States sources and (ii) gross income that is effectively connected with
a United States trade or business. A corporation will be classified as a PHC if
(i) at any time during the last half of the corporation's taxable year, five or
fewer individuals own more than 50% of the corporation's stock (by value)
 
                                      143
<PAGE>
 
directly or indirectly and (ii) the corporation receives at least 60% of its
gross income, as adjusted, from certain passive sources. However, if a
corporation is an FPHC or a PFIC, it cannot be a PHC. It is possible that the
Issuer and its subsidiaries could meet the PHC shareholder test in a given
taxable year. It is also possible that the Issuer or one of its subsidiaries
would meet the income test in a given year and would be treated as a PHC. The
Company intends to manage its affairs so as to attempt to avoid or minimize the
imposition of the PHC tax, to the extent such management of its affairs is
consistent with its business goals, although there can be no assurance in this
regard.
 
 Controlled Foreign Corporations
 
  If 10% Shareholders (as defined above) own, in the aggregate, more than 50%
(measured by voting power or value) of the shares of the Issuer or any of its
non-United States subsidiaries (directly, indirectly, or by attribution), the
Issuer or any such non-United States subsidiary would be a CFC. If
characterized as CFCs, then a portion of the undistributed income of the Issuer
and its non-United States subsidiaries may be includible in the taxable income
of 10% Shareholders of those entities, and a portion of the gain recognized by
such 10% Shareholders on the disposition of their shares in the Issuer (which
could otherwise qualify for capital gains treatment) may be converted into
ordinary dividend income. It is possible that the Issuer and its non-United
States corporate subsidiaries may be CFCs or may become CFCs in the future.
However, as discussed above, CFC status generally only has potentially adverse
consequences to 10% Shareholders.
 
EXCHANGE NOTES
 
 Interest and OID on the Exchange Notes
 
  The tax treatment of the Exchange Notes will depend upon whether they are
issued with OID. Exchange Notes issued on or before June 1, 2002 will be issued
with OID. Exchange Notes issued after June 1, 2002 may be issued with OID, but
only if their principal amount exceeds their issue price, as defined above. The
interest (including OID) generally will be treated as foreign source passive
income (or, in the case of certain United States Holders, foreign source
financial services income) for foreign tax credit purposes. Exchange Notes
issued with OID will be referred to as "OID Notes."
 
 Stated Interest
 
  Payments of interest on Exchange Notes issued after June 1, 2002 generally
will be includible in a United States Holder's income as ordinary income under
the United States Holder's method of accounting for United States federal
income tax purposes. However, because the Issuer has the option through June 1,
2002 to pay interest on the Exchange Notes by issuing additional Exchange
Notes, Exchange Notes issued prior to that date will be treated as issued with
OID, and stated interest on such Exchange Notes would not be treated as
interest for United States federal income tax purposes, but instead will be
subject to the OID rules described below.
 
 Original Issue Discount
 
  An Exchange Note will be issued with OID to the extent that its "stated
redemption price at maturity" exceeds its "issue price" by more than a de
minimis amount (i.e., .25% of the stated redemption price at maturity
multiplied by the number of complete years to maturity.) United States Holders
of OID Notes will be subject to special tax accounting rules, as described in
greater detail below. United States Holders of OID Notes should be aware that
they generally must include OID in gross income for United States federal
income tax purposes on an annual basis under a constant yield accrual method.
As a result, such United States Holders will include OID in income in advance
of the receipt of cash attributable to that income. However, United States
Holders of OID Notes generally will not be required to include separately in
income cash payments received on such OID Notes, even if denominated as
interest, to the extent such payments do not constitute qualified stated
interest (as defined below). The Issuer will report to United States Holders of
any Exchange Notes with OID on a timely basis the reportable amount of OID and
interest income based on its understanding of applicable law.
 
                                      144
<PAGE>
 
  The "stated redemption price at maturity" of a debt instrument is the sum of
its principal amount plus all other payments required thereunder, other than
payments of "qualified stated interest." For this purpose, "qualified stated
interest" means stated interest that is unconditionally payable in cash or in
property (other than the debt instruments of the company), at least annually at
a single fixed rate during the entire term of the debt instrument that
appropriately takes into account the length of the intervals between payments.
If the Exchange Notes are issued at a time when the Issuer has the option to
pay interest on the Exchange Notes by issuing additional Exchange Notes, none
of the stated interest on such Exchange Notes will be treated as qualified
stated interest so that all of such payments will be included in the "stated
redemption price at maturity" and the Exchange Notes will be issued with OID.
If Exchange Notes are issued when the Issuer does not have such an option, then
the stated interest on the Exchange Notes will be qualified stated interest,
includible in income in accordance with the United States Holder's method of
accounting, but Exchange Notes may still be issued with OID to the extent that
the issue price is less than the principal amount. The "issue price" of an
Exchange Note will be determined as described under "--Disposition of Preferred
Stock."
 
  The amount of OID includible in income by the initial United States Holder of
an OID Note is the sum of the "daily portions" of OID with respect to the OID
Note for each day during the taxable year or portion of the taxable year in
which such United States Holder held such OID Note ("accrued OID"). The daily
portion is determined by allocating to each day in any "accrual period" a pro
rata portion of the OID allocable to that accrual period. The "accrual period"
for an OID Note may be of any length and may vary in length over the term of
the OID Note, provided that each accrual period is no longer than one year and
each scheduled payment of principal or interest occurs on the first day or the
final day of an accrual period. The amount of OID allocable to any accrual
period is an amount equal to the excess, if any, of (a) the product of the OID
Note adjusted issue price at the beginning of such accrual period and its yield
to maturity (determined on the basis of compounding at the close of each
accrual period and properly adjusted for the length of the accrual period) over
(b) the sum of any qualified stated interest allocable to the accrual period.
OID allocable to a final accrual period is the difference between the amount
payable at maturity (other than a payment of qualified stated interest) and the
adjusted issue price at the beginning of the final accrual period. Special
rules will apply for calculating OID for an initial short accrual period. The
"adjusted issue price" of an OID Note at the beginning of any accrual period is
equal to its issue price increased by the accrued OID for each prior accrual
period (determined without regard to the amortization of any acquisition or
bond premium, as described below) and reduced by any payments made on such OID
Note (other than qualified stated interest) on or before the first day of the
accrual period. Under these rules, a United States Holder will have to include
in income increasingly greater amounts of OID in successive accrual periods.
 
 Amortizable Bond Premium
 
  If at the time the Preferred Stock is exchanged for the Exchange Notes, the
United States Holder's tax basis in any such Exchange Notes exceeds its stated
redemption price at maturity, the Exchange Notes will be considered to have
been issued at a premium. A United States Holder generally may elect to
amortize the premium over the term of the Exchange Notes on a constant yield
method as an offset to interest when includible in income under the United
States Holder's regular accounting method. The election to amortize premium on
a constant yield method once made applies to all debt obligations held or
subsequently acquired by the electing United States Holder on or after the
first day of the first taxable year to which the election applies and may not
be revoked without the consent of the IRS.
 
 Redemption, Sale or Exchange of Exchange Notes
 
  The adjusted tax basis of a United States Holder who receives Exchange Notes
in exchange for Preferred Stock will, in general, be equal to the initial tax
basis of such Exchange Notes, increased by any OID previously included in
income by the United States Holder and reduced by any cash payments on the
Exchange Notes other than qualified stated interest. Upon the redemption, sale,
exchange or retirement of an Exchange Note, a United States Holder will
recognize gain or loss equal to the difference between the amount realized upon
the redemption, sale, exchange or retirement (less any amount attributable to
accrued qualified stated
 
                                      145
<PAGE>
 
interest that has not previously been included in income, which will be taxable
as such) and the adjusted tax basis of the Exchange Notes. Such gain or loss
will be capital gain or loss. Net capital gains of individuals derived in
respect of capital assets held for more than one year are eligible for reduced
rates of taxation. The deductibility of capital losses is subject to
limitations. Any gain recognized by a United States Holder generally will be
treated as United States source income. It is presently unclear whether any
loss realized by a United States Holder will be treated as United States or
foreign source.
 
  PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
CONSEQUENCES OF OWNING EXCHANGE NOTES.
 
 TAXATION OF NON-UNITED STATES HOLDERS
 
  For United States federal income tax purposes, a non-United States Holder
should not be subject to tax on distributions made with respect to, and gains
realized from the disposition of, Preferred Stock or Exchange Notes 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
 
  United States Holders. In general, information reporting requirements will
apply to dividends in respect of the Preferred Stock, certain payments of
principal, interest, OID and premium on the Exchange Notes, and the proceeds
received on the sale, exchange, or redemption of the Preferred Stock and
Exchange Notes paid within the United States (and in certain cases, outside of
the United States) to United States Holders other than certain exempt
recipients (such as corporations). A 31% backup withholding may apply to such
amounts if the United States Holder fails to provide an accurate taxpayer
identification number or to report dividends required to be shown on its United
States federal income tax returns. The amount of any backup withholding from a
payment to a United States Holder will be allowable as a credit against the
United States Holder's United States federal income tax liability.
 
  Non-United States Holders. Under current law, United States information
reporting requirements and backup withholding generally will not apply to
dividends paid on the Preferred Stock to a non-United States Holder at an
address outside the United States (unless the payer has knowledge that the
payee is a United States person). However, under recently finalized United
States Treasury regulations (the "Final Regulations") effective for payments
made after December 31, 1999, a non-US Holder will generally be subject to
back-up withholding unless applicable certification requirements are met.
 
  With respect to payment of interest on the Exchange Notes, no information
reporting or backup withholding will be required with respect to payments made
to non-United States Holders if the beneficial owner of such Note, or financial
institution holding the Note on behalf of such owner, provides, in accordance
with specified procedures, a paying agent of the Issuer with a statement to the
effect that the beneficial owner is not a United States Holder (or the holder
otherwise establishes an exemption). Under current law, such requirement may be
met if the beneficial owner certifies under penalty of perjury that it is a
non-United States Holder (which certification may be made on IRS Form W-8 (or
successor form)) and the payor does not have actual knowledge that the
beneficial owner is a United States person. Under the Final Regulations, the
requirement may also be satisfied with other documentary evidence for interest
paid after December 31, 1999 with respect to an offshore account or through
certain foreign intermediaries.
 
  As a general matter, information reporting and backup withholding will not
apply to a payment of the proceeds of a sale of Preferred Stock and Exchange
Notes effected outside the United States by a foreign office of a non-United
States Holder. However, payment of the proceeds of a sale of Preferred Stock
and Exchange
 
                                      146
<PAGE>
 
Notes within the United States or conducted through certain United States
related financial intermediaries is subject to both backup withholding and
information reporting unless the certification provided for above is provided
or the holder otherwise establishes an exemption.
 
  Any amounts withheld under the backup withholding rules from a payment to a
non-United States Holder will be allowed as a refund or a credit against such
non-United States Holder's United States Federal income tax, provided that the
required information or appropriate claim for refund is furnished to the IRS.

                              PLAN OF DISTRIBUTION
 
  Until       , 1999 (40 days after the date of this prospectus), all dealers
effecting transactions in the Exchange Preferred Stock (or any New Exchange
Notes issued in exchange therefor), whether or not participating in this
distribution, may be required to deliver a prospectus. This is in addition to
the obligation of dealers to deliver a prospectus when acting as underwriters
and with respect to their unsold allotments or subscriptions.
 
  Each broker-dealer that receives shares of Exchange Preferred Stock (or any
New Exchange Notes issued in exchange therefor) for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such shares of Exchange Preferred Stock (or any
New Exchange Notes issued in exchange therefor). This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of shares of Exchange Preferred Stock (or any New
Exchange Notes issued in exchange therefor) received in exchange for shares of
Old Preferred Stock only where such shares of Old Preferred Stock were acquired
as a result of market-making activities or other trading activities. The
Company has agreed that it will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale for a period of one year from the date on which the Exchange Offer
is consummated, or such shorter period as will terminate when all shares of Old
Preferred Stock acquired by broker-dealers for their own accounts as a result
of market-making activities or other trading activities have been exchanged for
shares of Exchange Preferred Stock and such shares of Exchange Preferred Stock
(or any New Exchange Notes issued in exchange therefor) have been resold by
such broker-dealers.
 
  The Company will not receive any proceeds from any sale of Exchange Preferred
Stock (or any New Exchange Notes issued in exchange therefor) by broker-
dealers. Shares of Exchange Preferred Stock received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the shares of Exchange
Preferred Stock (or any New Exchange Notes issued in exchange therefor) or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such 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 such broker-dealer and/or the purchasers of any shares of
Exchange Preferred Stock (or any New Exchange Notes issued in exchange
therefor). Any broker-dealer that resells shares of Exchange Preferred Stock
(or any New Exchange Notes issued in exchange therefor) that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such shares of Exchange Preferred Stock
(or any New Exchange Notes issued in exchange therefor) may be deemed to be an
"underwriter" within the meaning of the Securities Act of 1933 and any profit
on any such resale of shares of Exchange Preferred Stock (or any New Exchange
Notes issued in exchange therefor) 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.
 
  For a period of one year from the date on which the Exchange Offer is
consummated, or such shorter period as will terminate when all shares of Old
Preferred Stock acquired by broker-dealers for their own accounts as a result
of market-making activities or other trading activities have been exchanged for
shares of Exchange Preferred Stock and such shares of Exchange Preferred Stock
(or any New Exchange Notes issued in exchange therefor) have been resold by
such broker-dealers, the Company will promptly send additional copies of this
prospectus and any amendment or supplement to this prospectus to any broker-
dealer that requests such documents in the Letter of Transmittal. The Company
has agreed to pay all expenses incident to the Exchange Offer other than
commissions or concessions of any brokers or dealers and the fees of any
counsel or other advisors or experts retained by the holders of Preferred
Stock, except as expressly set forth in the Registration Rights Agreement, and
will indemnify the holders of Preferred Stock (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act of
1933.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholder of
Global Crossing Holdings Ltd.:
 
  We have audited the accompanying consolidated balance sheet of Global
Crossing Holdings Ltd. (a Bermuda company in its development stage) and
subsidiaries as of December 31, 1997, and the related consolidated statements
of operations, shareholder's equity and cash flows for the period from March
19, 1997 (Date of Inception) to December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audit.
 
  We conducted our audit in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Global Crossing Holdings Ltd.
and subsidiaries as of December 31, 1997, and the results of their operations
and their cash flows for the period from March 19, 1997 (Date of Inception) to
December 31, 1997, in conformity with accounting principles generally accepted
in the United States.

                 AS OF SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
  (INFORMATION FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998,
  FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997, AND FOR THE PERIOD FROM MARCH
                                    19, 1997

                          (EXPRESSED IN U.S. DOLLARS)
1. BACKGROUND
 
  On April 30, 1998, Global Crossings Holdings Ltd. ("GCH" and together with
its subsidiaries, the "Company"), a Bermuda company, was formed as a wholly-
owned subsidiary of Global Crossing Ltd. (together with its subsidiaries,
"GCL"), a Bermuda company which was a wholly-owned subsidiary of Global
Crossing Ltd., LDC ("OLD GCL"). Because Old GCL, GCL and GCH are entities under
common control, GCH's financial statements are presented as if it was in
existence on March 19, 1997 (Date of Inception) of OLD GCL similar to a pooling
of interest. (See Note 11 for a summary of GCL's consolidated financial
information.)
 
  On March 19, 1997, Old GCL, (formerly GT Parent Holdings LDC), was
incorporated as an exempted limited duration company in the Cayman Islands.
When GCL was formed on March 18, 1998, Old GCL contributed its investment in
Global Telesystems Holdings Ltd. ("GTH") to GCL which contributed it to GCH
upon its formation. GCL is an independent developer, owner and operator of
undersea and terrestrial digital fiber optic cable systems. Atlantic Crossing
Ltd. ("ACL"), formerly Global Telesystems Ltd., a Bermuda company which is an
indirect wholly-owned subsidiary of GCL, was incorporated to construct and
operate an undersea fiber optic cable ring with landing stations in the United
States, the United Kingdom, Germany and the Netherlands. ACL has incorporated
wholly-owned subsidiaries in each of these countries in order to own the
portion of the cable system located in each country and the related territorial
waters.
 
  Prior to GCL's Initial Public Offering, which took place on August 13, 1998,
GCL declared a stock dividend to Old GCL resulting in Old GCL holding 1.5
shares of common stock of GCL for each share of common stock of Old GCL
outstanding. Pursuant to the terms of the Article of Association of Old GCL and
prior to the Initial Public Offering, each holder of Class D shares converted
such shares into a fraction of a Class E share based upon a valuation at the
time of such conversion, together with a warrant to purchase the remaining
fraction of such Class E share at an exercise price based upon such market
valuation. In addition, each holder of Class E shares of Old GCL had such Class
E shares converted into Class B shares of Old GCL. Accordingly, each holder of
Class D and Class E shares ultimately received Class B shares, with the
warrants to purchase Class E shares received by former Class D shareholders
then cancelled in exchange for warrants ("GCL Warrants") to purchase shares of
GCL Common Stock at an exercise price equal to the price to Public Per Share
payable in the Initial Public Offering.
 
  After the above transaction and prior to the Initial Public Offering, each
shareholder of Old GCL (other than CIBC) agreed with GCL to exchange their
interests in Old GCL for shares of GCL Common Stock held by Old GCL at a rate
of 1.5 shares of GCL Common Stock per share of common stock of Old GCL ("Old
GCL Exchange"). CIBC did not participate in the above transaction and continues
to maintain its beneficial ownership position in GCL through Old GCL.
Subsequent to this exchange, each previous shareholder of Old GCL holds an
equal proportionate interest in GCL, with Old GCL becoming wholly-owned by
CIBC.
 
  Because Old GCL, GCL and GCH are entities under common control, the transfers
by Old GCL to GCL and GCL to GCH and the Old GCL Exchange were accounted for
similar to a pooling of interests. The financial statements presented have been
restated to reflect these transactions as if they had occurred as of March 19,
1997 (date of inception) (see Note 11.)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                 AS OF SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
  (INFORMATION FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998,
  FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997, AND FOR THE PERIOD FROM MARCH
                                    19, 1997
            (DATE OF INCEPTION) TO SEPTEMBER 30, 1997 IS UNAUDITED)
                          (EXPRESSED IN U.S. DOLLARS)
 
  GCL entered into a joint venture, Pacific Crossing Ltd., ("PCL") for purposes
of constructing and operating PC-1, an undersea fiber optic cable ring system
connecting California, Washington and two landing sites in Japan (see Note 3).
 
  Mid-Atlantic Crossing Ltd., a wholly-owned subsidiary of GCH, entered into a
contract with Alcatel Submarine Networks on June 2, 1998 for the construction
of MAC, an undersea fiber optic cable ring connecting New York, the Caribbean
and Florida at a total cost of $350 million. Mid-Atlantic Crossing Ltd. is in
the process of incorporating companies in each country in which the cable will
land in order to own the portion of the cable system located in each country
and the related territorial waters. To finance, in part, the construction of
MAC, the Company signed a commitment letter to obtain $240 million of senior
secured non-recourse indebtedness.
 
  During July, 1998, the Company through its wholly-owned subsidiary Pan
American Crossing Ltd., entered into a contract with Tyco Submarine Systems
Ltd. ("TSSL"), for the construction of PAC, an undersea fiber optic cable
system connecting California, Mexico, and Panama at a total cost of
approximately $475 million. To finance, in part, the construction of PAC, Pan
American Crossing Ltd. signed a commitment letter to obtain $300 million of
non-recourse indebtedness on July 21, 1998.
 
  During October 1998, the Company announced the development of Pan European
Crossing (PEC), a 7,200 kilometer terrestrial system connecting 18 European
cities to each other and to the undersea systems. The construction costs of PEC
are approximately $700 million. The Company signed an agreement, during
November 1998, valued at approximately $100 million with Cable & Wireless PLC
for the sale of dark fiber on its PEC network. Together, AC-1, MAC, PAC, PC-1
and PEC are defined as Systems.
 
  To finance construction of ACL's undersea fiber optic cable ring, GCL issued
$75 million of GCL Common Stock and GTH, an indirect wholly-owned subsidiary of
GCL, and the parent of ACL, issued $100 million of preference shares and sold
$150 million of senior notes, as described in Note 6. These proceeds, together
with a $482 million Credit Facility, as described in Note 5, are being used to
pay for construction costs, financing fees and other related costs.
 
  ACL has entered into a fixed price contract (the "Contract") with TSSL for
the development, design, construction and installation of a four fiber pair,
fiber optic cable system connecting (i) the United States to the United
Kingdom, (ii) the United Kingdom to the Netherlands and Germany, (iii) The
Netherlands to Germany and (iv) Germany to the United States (collectively,
"AC-1" and "System"). AT&T Corp. has provided ACL with a guarantee in respect
of TSSL's obligations under the Contract. Assuming that construction of AC-1
progresses according to the Contract schedule, AC-1 will be accepted by ACL and
made available for commercial service on February 22, 1999 (the "System RFS
date"). Certain segments of AC-1 are expected to be completed in advance of the
System RFS date. The United States to the United Kingdom segment was ready for
service on May 26, 1998 and the Germany to the United States segment is
expected to be ready for service on November 30, 1998. Once ACL formally
accepts each segment of AC-1, the segment becomes ready for service and the
ownership of the segment assets transfers to ACL and its subsidiaries. The only
exception to this transfer of ownership is in respect of certain of the segment
assets located in United States territory to which TSSL retains title until
such time as GT Landing Corp., a United States wholly-owned subsidiary of ACL,
exercises its $10,000 bargain purchase option to purchase title. Pursuant to
the Contract, TSSL granted

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                 AS OF SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
  (INFORMATION FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998,
  FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997, AND FOR THE PERIOD FROM MARCH
                                    19, 1997

                          (EXPRESSED IN U.S. DOLLARS)
GT Landing Corp. an indefeasible right of use ("IRU"), for the estimated life
of AC-1 of 25 years from the System RFS date. GT Landing Corp. has accounted
for the IRU as a capital lease, since the IRU transfers the risks and rewards
of ownership to GT Landing Corp. The United States assets governed by this IRU
includes all landing stations assets (with the exception of the building and
land, to which GT Landing Corp. has title), fiber optic cable located in the
United States and the landing license.
 
  Customers of the Company enter into Capacity Purchase Agreements ("CPA") to
obtain an IRU in units of transatlantic and European capacity ("AC-1
Capacity"). The purchase price for AC-1 Capacity is non-refundable once the
segment of AC-1 specified in the CPA is ready for service and the IRU entitles
the customer to all rights and obligations of ownership of the AC-1 capacity
for a period ending 25 years after the System RFS date. The Company's CPAs
provide that AC-1 will have self-healing ring capability, whether or not a CPA
relates only to a segment of AC-1. Self-healing capability enables capacity on
the segment of AC-1 to be instantaneously restored either on AC-1 other
segments or within the same segment in the event of interruption so that the
same point-to-point connectivity is maintained.
 
  Customers who purchase AC-1 capacity prior to the System RFS date will be
granted 80% of the capacity that remains unsold, if any, 12 1/2 years after the
System RFS date. However, based on sales projections provided by a third party
consultant, it is highly unlikely that there will be a material amount of
unsold capacity on AC-1 at the end of 12 1/2 years after the System RFS date.
The Company has no constraints on the pricing or structure of sales of residual
capacity and the Company would expect that if such capacity had any remaining
value, it would enter into one or more transactions to dispose of such capacity
prior to such date to realize such remaining value. As a result, the right to
residual capacity is not a substantive right.
 
  ACL subsidiaries have entered into contracts, called Inland Services
Agreements, to obtain IRUs of capacity on terrestrial telecommunications
systems for terms of 25 years from the System RFS date. Under the IRU, the
Company is required to pay an up-front non-recurring charge plus, in certain
cases, monthly recurring charges over a 25 year period and in exchange obtains
all rights and obligations of ownership. The Company has accounted for the IRUs
as capital leases since these IRUs represent leases as defined under Statement
of Financial Accounting Standards No. 13, "Accounting for Leases" ("SFAS 13").
The Company sells this terrestrial capacity under separate CPAs ("Terrestrial
CPA") to certain customers that have purchased capacity on AC-1 for the purpose
of extending capacity from AC-1 landing stations to major telecommunication
centers in the United States and the United Kingdom. The purchase price for
terrestrial capacity is non-refundable and grants the customer an IRU which
entitles the customer to all rights and obligations of ownership of the
terrestrial capacity for a period ending 25 years after the System RFS date.
 
  ACL has entered into an Operations, Administration and Maintenance ("OA&M")
agreement with TSSL whereby TSSL is obligated to provide operating,
administration and maintenance functions to AC-1. The administration functions
include but are not limited to the provision of billing information and annual
expense budgets. The operations and maintenance functions include but are not
limited to the management and maintenance of a Network Operating Center,
assumption of ship costs and any related ship repair costs, obtaining and
renewing all operating permits, providing repair equipment, providing cable
protection and ordering and restocking spares. The OA&M Agreement is for an
initial term of eight years with two renewal periods of eight and one half
years each. Quarterly payments under the OA&M Agreement to TSSL will commence
as ACL accepts ownership to the various segments.

                          (EXPRESSED IN U.S. DOLLARS)
 
  Pursuant to the terms of CPAs, ACL is obliged to use commercially reasonable
efforts to cause AC-1 to be maintained in efficient working order and in
accordance with industry standards. In exchange for the operating,
administration and maintenance services provided by ACL through the OA&M
agreement with TSSL, customers are obligated for the term of the IRU to pay for
their allocable share of the costs for operating and maintaining the AC-1. In
accordance with the CPA, customers appoint members to a System Advisory
Committee which is charged with the responsibility of directing the operations
and maintenance of the System. Customers pay for 110% of ACL's cost to operate
and maintain the system based on their pro-rata share of total capacity subject
to annual maximum amounts per circuit purchased of $250,000 per transatlantic
circuit and $50,000 per European circuit. Their pro-rata share is effectively
calculated by taking the weighted average of purchased capacity over total
capacity multiplied by 110% of actual costs incurred. These OA&M costs are
billed to customers quarterly in advance based on the prior year's actual
costs, are non-refundable, and should a customer fail to make an OA&M payment,
ACL may suspend all rights to capacity granted under the IRU.
 
  ACL originally entered into a Sales Agency Agreement with TSSL whereby TSSL
was responsible for the marketing and sale of capacity of the System and
received commissions on sales proceeds received at rates that varied as certain
cumulative revenue levels were reached. Effective March 5, 1998, the Company
entered into a commissions sharing agreement with TSSL whereby GCH assumed
primary responsibility for the marketing and sale of capacity of the System and
will share a percentage of commissions payable to TSSL under the Sales Agency
Agreement as consideration for assuming primary responsibility for the sales
effort and marketing of the Company's projects. The Sales Agency Agreement with
TSSL will terminate on March 25, 2002 with an option to extend it until March
25, 2005.
 
  On January 21, 1998, Old GCL effected a 100-for-1 stock split of each of the
Class A, B, C and D common stock and undesignated stock and amended the par
value of each share of common stock from $.0001 per share to $.000001 per
share. All share information presented in the consolidated financial
statements, including these notes, gives effect to the stock split.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  These consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in the United States. The preparation
of financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates. The significant accounting policies
are summarized as follows:
 
 a) Principles of Consolidation
 
  The consolidated financial statements include the accounts of GCH and its
wholly owned subsidiaries. All significant intercompany transactions have been
eliminated. Investment in PCL, in which GCH does not exercise control, has been
accounted for using the equity method.
 
 b) Development Stage Company
 
  The Company was in its development stage until May 26, 1998 when the United
States to United Kingdom segment of the AC-1 system was placed into service and
the Company began generating significant

                 AS OF SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
  (INFORMATION FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998,
  FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997, AND FOR THE PERIOD FROM MARCH
                                    19, 1997
            (DATE OF INCEPTION) TO SEPTEMBER 30, 1997 IS UNAUDITED)
                          (EXPRESSED IN U.S. DOLLARS)
revenues. All segments of AC-1 are scheduled to be ready for commercial service
by February 1999. Currently, construction of the Company's other undersea and
terrestrial fiber optic cable systems are underway.
 
  Successful future operations are subject to several risks, including the
ability of the Company to ensure the successful, timely and cost-effective
completion of AC-1 and other cable systems as well as to successfully market
and generate significant revenue from the sale of capacity of the system. GCH
may encounter problems, delays and expenses, many of which may be beyond its
control. There can be no assurance that the cable systems will be completed
within the time frame and that capacity sales will meet expectations, or that
substantial delays would not adversely affect GCH's achievement of profitable
operations.
 
 c) Cash and Cash Equivalents
 
  The Company considers short-term highly liquid investments with an original
maturity of three months or less at the date of purchase to be cash
equivalents. Cash and cash equivalents include cash in banks and short-term
money market deposits with a maturity of one month.
 
 d) Sales, Cost of Sales and Deferred Revenue
 
  The Company enters into CPAs to sell capacity on its undersea and terrestrial
fiber optic systems. These CPAs grant the customer an IRU of capacity for the
life of the cable which is 25 years from the ready for service date. Sales of
capacity under CPAs are accounted for as sales type leases as they represent
leases of property and meet the criteria for sales-type lease accounting under
SFAS 13.
 
  Revenues from the sale of capacity are recognized in the period that the
rights and obligations of ownership transfer to the purchaser, which occurs
when (1) the purchaser obtains the right to use the capacity, which can only be
suspended if the purchaser fails to pay the full purchase price or fulfill its
contractual obligations, (2) the purchaser is obligated to pay OA&M costs and
(3) the segment of the system related to the capacity purchased is available
for service. Customers who have entered into CPAs for AC-1 capacity have paid
deposits toward the purchase price and such amounts have been included as
deferred revenue in the accompanying consolidated balance sheet. Certain CPAs
require a refund of these deposits should the System RFS date occur after June
30, 1999. The Company's CPAs provide that the AC-1 system will have self-
healing ring capability, whether or not a customer purchases capacity on a
single segment of the system. Substantially all of the Company's customers to
date for AC-1 have assumed the risk of full ring completion. In some CPAs,
customers who have purchased capacity on the United States to United Kingdom
segment prior to the date the full AC-1 ring is operational have contractually
required full self-healing ring capability as a legal condition which, if not
satisfied, would enable them to terminate the CPA and require the Company to
refund capacity payments. Payments received relating to these CPAs are included
in deferred revenue on the consolidated balance sheet until the full self-
healing ring is operative.
 
  Costs incurred on each segment of the System, currently reflected as
construction in progress in the accompanying consolidated balance sheet, is
recorded as capacity available for sale at the date each segment of the system
becomes operational. AC-1 capacity available for sale is recorded at the lower
of cost or fair value less costs to sell and will be charged to costs of sales
in the period the related revenues are recognized. Fair value of AC-1 capacity
will be derived from a third party consultant's market study of expected sales
of capacity.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                 AS OF SEPTEMBER 30, 1998 AND DECEMBER 31, 1997
  (INFORMATION FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998,
  FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997, AND FOR THE PERIOD FROM MARCH
                                    19, 1997
            (DATE OF INCEPTION) TO SEPTEMBER 30, 1997 IS UNAUDITED)
                          (EXPRESSED IN U.S. DOLLARS)
 
  Cost of sales in any period relating to capacity is calculated based on the
ratio of capacity revenues recognized in the period to total expected capacity
revenues over the life of the system multiplied by the total costs incurred to
construct the system. This calculation of the cost of sales amount matches
costs with the value of each sale relative to total expected revenues. Until
the entire System is completed, for purposes of calculating cost of sales, the
total System costs incurred will include an estimate of remaining costs to be
incurred to complete the entire System. When needed, terrestrial capacity is
purchased from third party capacity providers, to fulfill the Company's
commitments under Terrestrial CPA agreements. The cost of acquiring third party
capacity will be charged to cost of sales in the period that the related
revenue is recognized.
 
  The calculation of cost of underseas sales is based on a total system cost
and revenue forecast that includes both the initial system cost and the cost of
system upgrades that management has the intent and ability to complete,
provided the need for such upgrades is supported by a consultant's independent
revenue forecast.
 
  The AC-1 System is designed to enable the Company to upgrade the System in
future years so as to increase the initial design capacity of 256 circuits
available for sale. The business plan for the investment in AC-1 indicated a
minimum capacity sales level of 512 circuits and management currently has both
the intent and ability to upgrade the system to that level. This is
demonstrated by the fact that (i) the Board of Directors has authorized the
purchase of the upgrade, (ii) the Company has the financial ability to purchase
the upgrade and (iii) there are no regulatory or technology issues preventing
the completion of the upgrade. In the period the Company purchases any further
upgrades, the total expected System capacity revenues and cost of the System
used in the cost of sales calculation will change to take into account the
further increase in System cost and in System capacity. The total expected
System capacity revenues used by the Company in its cost of sales calculation
will always be limited by total sales forecasted by a third party consultant
which will be updated on an annual basis. Based on the current third party
consultant's sales forecast, the Company expects to sell all 512 circuits
available for sale, which includes the initial upgrade.
 
  In addition to capacity upgrades, management's estimate of future expected
capacity revenues may change due to a number of factors including possible
variances in actual sales prices and volume from management's estimates.
Management will continually evaluate these factors in conjunction with the
updated third party consultant's sales forecast and, as necessary, revise its
estimate of the total expected revenues to be derived over the life of AC-1.
Changes in management's estimate of the total expected revenues to be derived
from sales of capacity will result in adjustments to the calculations of cost
of sales. These adjustments will be recorded on a prospective basis over future
periods commencing with the period management revises its estimate.
 
  Under their respective CPAs, certain customers have been provided options to
purchase additional capacity at specified prices for specified future periods
as well as the option to purchase additional capacity should the Company
upgrade the AC-1 capacity in the future. In many cases, prices under the
options to purchase capacity during these specified periods are lower than the
current price for capacity charged to the customer. Management's estimate of
future revenues for purposes of calculating cost of sales takes into
consideration prices under these options.
 
  Undersea and terrestrial OA&M revenues are recognized in the period the
services are provided. On an annual basis the actual OA&M costs incurred by the
Company will be accumulated and an adjustment will be made to true up actual
OA&M revenues so that they equal 110% of actual costs incurred, provided
specified

                          (EXPRESSED IN U.S. DOLLARS)
contractual limits have not been reached. This adjustment will be recorded in
the period in which the adjustment is made.
 
 e) Commissions and Advisory Services Fees
 
  The Company's policy is to record the commission and advisory fee expense and
related payable upon the recognition of revenue so as to appropriately match
these costs with the related revenue. Under the Advisory Services Agreement
("ASA"), the Company pays PCG Telecom Services LLC ("PCG Telecom") and its
affiliates 2% of revenues for advisory services performed and under the Sales
Agency Agreement pays TSSL a commission based on a percentage of capacity
revenues. See Note 12 for discussion of the termination of the ASA.
 
 f) Capacity Available For Sale
 
  The cost of acquiring terrestrial capacity under Inland Service Agreements
has been capitalized to capacity available for sale. Under these agreements the
Company is required to pay an up-front non-recurring charge plus, in certain
cases, recurring charges over the period the capacity is provided. The Company
has capitalized the present value of total future payments (excluding OA&M
costs) in capacity available for sale and has recorded an equal amount as an
obligation under Inland Services Agreements in the accompanying consolidated
balance sheets (see Note 5). The related OA&M costs will be expensed in the
period the services are provided.
 
 g) Construction in Progress
 
  Construction in progress includes direct expenditures for construction of AC-
1 and is stated at cost. Capitalized costs include costs incurred under the
Contract; advisory, consulting and legal fees; interest; and amortized finance
costs incurred during the construction phase. Once it is probable that a cable
system will be constructed, costs directly identifiable with the cable system
under development are capitalized. Costs relating to the evaluation of new
projects incurred prior to the date development of the cable system becomes
probable are expensed as incurred.
 
  Additionally, the Company has included in construction in progress the
minimum lease payments related to the IRU held by GT Landing Corp. on AC-1
assets in the United States and minimum lease payments related to leases of
buildings and conduits in Germany and The Netherlands described further in Note
5.
 
  Interest incurred which includes the amortization of deferred finance fees
and the issuance discount, ("interest cost") are capitalized to construction in
progress in accordance with Statement of Financial Accounting Standards No. 34,
"Capitalization of Interest Costs" ("SFAS 34"). Total interest cost incurred
and interest capitalized to construction in progress during the periods were:

 h) Deferred Finance and Organization Costs
 
  Costs incurred to obtain financing through the issuance of senior notes and
long term debt have been reflected as an asset in the accompanying
consolidated balance sheets. Costs incurred to obtain financing through the
issuance of GCL Common Stock and preference shares, respectively, have been
reflected as a reduction in the carrying value of the issued common and
preference shares. The financing costs relating to the debt are amortized over
the term of the related debt agreements. Offering costs of $7,529,651 related
to the issuance of preference shares were being amortized on a straight line
basis through the mandatory redemption date of April 1, 2007. The issuance
discount, as explained in Note 7, was also being amortized through the
mandatory redemption date. On June 17, 1998 the preference shares were
redeemed at which time the remaining balance of unamortized discount and
offering costs was charged against additional paid-in-capital. During the
construction period, the amortized portion of deferred financing costs
relating to the senior notes and the long term debt are included in
construction in progress as a component of interest capitalized or recorded as
interest expense in accordance with SFAS 34. The amortized portion of the
deferred financing costs relating to the preference shares is included as a
component of preference share dividends.
 
 i) Translation of Foreign Currencies
 
  Transactions in foreign currencies are translated into United States dollars
at the rate of exchange prevailing at the date of each transaction. Monetary
assets and liabilities denominated in foreign currencies at year end are
translated into United States dollars at the rate of exchange at that date.
Resulting gains or losses on exchange are recorded as other income or loss in
the statement of operations.
 
 j) Stock Option Plan
 
  Employees of GCH and its subsidiaries participate in the stock option plan
of GCL and GCH is therefore allocated its applicable share of stock related
compensation expense.
 
 k) Interest Rate Derivatives
 
  The Company uses derivative financial instruments for the purpose of
reducing its exposure to adverse fluctuations in interest rates. The Company
does not utilize derivative financial instruments for trading or other
speculative purposes. The counterparty to these instruments is CIBC. The
Company is exposed to credit loss in the event of nonperformance by this
counterparty.
 
  As discussed in Note 5, effective December 31, 1997, the Company entered
into an interest rate swap agreement to hedge its exposure to interest rates
on its long term debt. The net cash amounts paid or received on the agreement
are accrued and recognized as an adjustment to interest expense on the related
debt.
 
  For interest rate derivatives to qualify for hedge accounting, the debt
instrument being hedged must expose the Company to interest rate risk and, at
the inception of the derivative instrument and throughout the period the
derivative is held, there must be a high correlation of changes in the market
value of the derivative and interest expense of the hedged item. Gains and
losses on interest rate derivatives and other derivative instruments which do
not meet this criteria would be recorded in the statement of operations.

                          (EXPRESSED IN U.S. DOLLARS)
 
  Interest rate derivative instruments terminated or replaced by another
instrument and no longer qualifying as a hedge instrument are marked to market
and carried on the balance sheet at fair value.
 
 l) Interim Financial Information
 
  The unaudited financial statements as of September 30, 1998, and for the
three months and nine months ended September 30, 1998, for the three months
ended September 30, 1997 and for the period from March 19, 1997 (Date of
Inception) to September 30, 1997 include, in the opinion of management, all
adjustments considered necessary for the fair presentation of such financial
statements.
 
 m) Net Income (Loss) Per Share
 
  GCL's basic net income (loss) per share is computed using the weighted
average number of shares of GCL Common Stock outstanding. GCL's diluted net
income (loss) per share is computed using the weighted average number of shares
of GCL Common Stock outstanding and GCL Common Stock equivalents including
shares issuable under options and warrants that are dilutive using the treasury
stock method.
 
  Since the Company is a wholly-owned subsidiary of GCL, per share information
is not presented.
 
 n) Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
109"). The Company recognizes current and deferred income tax assets and
liabilities based upon all events that have been recognized in the consolidated
financial statements. Deferred tax assets and liabilities are determined based
on differences between the financial reporting and tax bases of assets and
liabilities. A deferred tax liability or asset is recorded using the enacted
tax rates expected to apply to taxable income in the period in which the
deferred tax liability or asset is expected to be settled or realized. Future
tax benefits attributable to these differences, if any, are recognized to the
extent that realization of such benefits is more likely than not.
 
 o) Pending and New Accounting Standards
 
  The Financial Accounting Standards Board has recently issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
130") and Statement of Financial Accounting Standards No. 131, "Disclosures
About Segments of an Enterprise and Related Information" ("SFAS 131"). SFAS 130
and SFAS 131 are effective for periods beginning after December 15, 1997. There
was no impact to the financial statements due to the adoption of SFAS 130 in
the first nine months of 1998. Management does not expect the impact of the
adoption of SFAS 131 on the Company's financial position or results of
operations to be material.
 
  The Financial Accounting Standards Board has also recently issued Statement
of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities," ("SFAS 133") which is effective for
periods beginning after June 15, 1999. Management does not expect the impact of
the adoption of SFAS 133 on the Company's financial position or results of
operations to be material.

3. INVESTMENT IN PACIFIC CROSSING LTD.
 
  On April 9, 1998, a wholly-owned subsidiary of GCH entered into a joint
venture to construct a cable system, PC-1. PC-1 is owned and operated by PCL.
The Company has an economic interest in PCL represented by a 50% direct voting
interest and, through one of the joint venture partners, owns a further 8%
economic non-voting interest. PCL entered into a contract on April 21, 1998
with TSSL to construct PC-1 for a total price of approximately $1.2 billion,
which will be financed through a $400 million equity contribution by the joint
venture partners and an $850 million credit facility. On July 30, 1998, an $850
million aggregate senior secured non-recourse loan facility ("the PCL Credit
Facility") was executed, for the construction and financing costs of PC-1. The
PCL Credit Facility is comprised of an $840 million multiple drawdown term loan
facility and a $10 million working capital facility. On July 30, 1998, an
initial drawdown was made on the term loan facility to repay the $104 million
promissory note used for initial construction costs on PC-1 as well as fees
incurred to secure the credit facility. The Company also placed $231 million
into a restricted cash collateral account on July 30, 1998 to satisfy its
equity funding commitment for its 58% joint venture economic interest in PCL.
This amount was accounted for as an equity investment in the joint venture.
 
  The investment in Pacific Crossing Ltd. consists of the following items:

  The PC-1 development costs represents the estimated value of the PCG Warrants
as of September 30, 1998 which were granted to PCG in exchange for the PC-1
system and related rights. In connection with the formation of PCL, the Company
agreed to make available to PCL the consideration received by the Company in
connection with the grant of the PCG Warrants, in addition to the $231 million
cash investment made by the Company. See Note 11.

5. LONG TERM DEBT AND OBLIGATIONS UNDER INLAND SERVICES AGREEMENTS AND CAPITAL
LEASES
 
  On June 27, 1997, ACL entered into a $410 million aggregate senior secured
non-recourse loan facility (the "Credit Facility") with a group of banks led by
CIBC and Deutsche Bank AG, for the construction and financing costs of AC-1. On
December 15, 1997, the Credit Facility was amended to increase it to $482
million comprised of a $472 million multiple draw down term loan facility (the
"Term Facility") and a $10 million working capital facility (the "Working
Capital Facility") for the purpose of extending AC-1 to include, among other
things, a Netherlands landing site. The Credit Facility is secured by pledges
of the stock of ACL and its subsidiaries and security interests in its assets
and revenues. As of September 30, 1998, ACL had outstanding $365,140,294
($162,325,000 as of December 31, 1997) under the Credit Facility. As of
September 30, 1998, $59,260,959 of the Credit Facility had been repaid to the
lenders ($nil as of December 31, 1997). Any amounts repaid to the lenders
cannot be re-borrowed, and are effectively permanent reductions in the Credit
Facility.
 
  Under the Credit Facility, ACL may select loan arrangements as either a
Eurodollar loan or an Alternative Base Rate ("ABR") Loan. The Eurodollar
interest rate is LIBOR plus 2.5% and the ABR interest rate is the greatest of
(a) the Prime Rate (b) the Base CD Rate plus 1% and (c) the Federal Funds
Effective Rate plus 0.5%, plus 1.5%. ACL pays a commitment fee of 0.5% per
annum on the unused portion of the Credit Facility. The Credit Facility
contains various covenants that, (i) limit further indebtedness by ACL and its
subsidiaries, (ii) limit the ability of ACL to pay dividends, (iii) require ACL
to meet certain minimum capacity sales levels and (iv) require ACL to meet a
minimum interest coverage ratio for the years 1999 through to maturity of the
Credit Facility. The Credit Facility will be repaid in eight semi-annual
installments ("Mandatory Repayments"), commencing on the first May 31 or
November 30 occurring two months after the AC-1 RFS date, with $72.3 million of
the principal amount due in the initial year and $120.5 million, $144.6
million, and $144.6 million due in the second, third and fourth years,
respectively. If at any semi-annual installment date the outstanding loan
balance is lower than the installment amounts noted in the previous sentence,
then the outstanding loan balance amount will be repaid. In addition, on each
semi-annual installment date, ACL will apply an amount equal to 50% of Excess
Cash Flow to the mandatory prepayment of the remaining outstanding balance
under the Credit Facility. Excess Cash Flow is defined under the terms of the
Credit Facility as all cash received from revenues during the period reduced by
the payment of OA&M expenses, commissions under the Sales Agency Agreement, and
transfers to certain reserve accounts. The Credit Facility also requires
mandatory prepayments to be made from 50% of net cash proceeds of any equity
offering of ACL and 100% of net cash proceeds from permitted debt offerings by
ACL or GTH. Optional prepayments may be made at any time without premium or
penalty. All revenues received prior to the RFS date are used to fund certain
reserve accounts, as defined by the Credit Facility, and thereafter applied
against the borrowings under the Credit Facility. However, any amounts repaid
to the lenders prior to the System RFS date can be used to reduce the Mandatory
Repayments.

  On September 30, 1997, pursuant to the Contract with TSSL and the Credit
Facility agreement, ACL put in place a $50 million letter of credit in favor
of TSSL which will expire at such time as ACL has paid all costs under the
contract. ACL pays a commitment fee of 2.5% per annum on the full amount of
the letter of credit. As of September 30, 1998, the letter of credit had been
reduced to $45.2 million.
 
  As of September 30, 1998, approximately $5 million was borrowed under the
working capital facility ($500,000 as of December 31, 1997), and approximately
$360 million was borrowed under the Term Facility ($162 million as of December
31, 1997). Effective December 31, 1997, ACL entered into an interest rate swap
transaction based on one month LIBOR to minimize its exposure to increases in
interest rates on its borrowings. The swap transaction was amended on February
2, 1998 and currently fixes ACL's floating interest rate at 5.7825% on a
notional amount of borrowings ranging between $200 million and $310 million
until January 31, 1999.
 
  As described in Note 1, the Company has capitalized the minimum lease
payments of the IRU held by GT Landing Corp. on AC-1 assets held in the United
States. The Company has been granted a bargain purchase option to purchase for
$10,000 all rights and title to these assets at any time during the term of
this contract which is 25 years from the System RFS date. As of September 30,
1998, the present value of the payments under the IRU recorded as an
obligation under capital leases is $4,107,615 ($12,297,645 as of December 31,
1997).
 
  The Company has capitalized building and conduit leases in The Netherlands
and Germany. The leases are for a period of 25 years which represents more
than 75 percent of the economic life of the asset being purchased. The Company
has the option to extend the Netherlands lease for an additional 5 year term.
As of September 30, 1998, the present value of the obligation has been
recorded as an obligation under capital leases in the accompanying
consolidated balance sheet in the amount of $8,011,503 ($ nil as of December
31, 1997.)
 
  Contracts to purchase terrestrial capacity have a duration of 25 years from
System RFS which represents more than 75 percent of the economic life of the
asset being purchased. Certain of these contracts require payments over the 25
year period. As of September 30, 1998, the present value of the payments under
these contracts (excluding amounts attributable to operations and maintenance)
has been recorded as obligations under Inland Services Agreements in the
accompanying consolidated balance sheets in the amount of $38,948,765
($20,900,000 as of December 31, 1997).

6. SENIOR NOTES
 
 New Senior Notes
 
  The 9 5/8% senior notes due May 15, 2008 with a face value of $800 million
("New Senior Notes") are general unsecured obligations of GCH and will rank
senior to any future subordinated indebtedness of GCH and pari passu in right
of payment with any future unsecured senior indebtedness of GCH. GCH has set
aside $74 million to fund the first two interest payments and is included in
the restricted cash balance. Interest is payable semi-annually in arrears on
each May 15 and November 15 commencing on November 15, 1998. The New Senior
Notes are redeemable at the option of GCH on May 15, 2003 at 104.813%, May 15,
2004 at 103.208%, on May 15, 2005 at 101.604% and on May 15, 2006 and on May 15
thereafter at par. The New Senior Notes are redeemable at the option of the
Holder only upon the occurrence of a change in control in GCL. The New Senior
Notes agreement imposes certain limitations on the ability of GCH and its
subsidiaries to, among other things, (i) incur additional indebtedness
including senior indebtedness and (ii) pay certain dividends and make certain
other restricted payments and investments.
 
 Old Senior Notes
 
  The 12% senior notes due March 31, 2004 with a face value of $150 million
("Old Senior Notes") are general unsecured obligations of GTH and will rank
senior to any future subordinated indebtedness of GTH and pari passu in right
of payment with any future unsecured senior indebtedness of GTH. The Old Senior
Notes bear an initial interest rate of 12% per annum. Interest is payable semi-
annually in arrears on each June 1 and December 1. If the Old Senior Notes are
not repaid by April 1, 2000, the interest rate will increase by 0.5% on April
1, 2000 and by an additional 0.5% on each subsequent April 1, until repaid. If
the interest rate exceeds 15% per annum (the interest rate payable increases by
2% upon any event of default) GTH may, at its option, cause such interest in
excess of 15% to be paid in additional senior notes.

  As described in Note 5, revenues received prior to the System RFS date are
used to fund certain reserve accounts which are then applied against borrowings
under the Credit Facility and the Old Senior Notes as determined by the Credit
Facility agreement. Additionally, GTH will on each June 1 and December 1,
commencing on the first such date to occur more than 90 days after the System
RFS date, apply an amount equal to 50% of ACL's Excess Cash Flow (as defined in
Note 5), to redeem the Old Senior Notes at face value, plus accrued interest to
the date of repurchase. The Old Senior Notes are redeemable at the option of
GTH, at redemption prices starting at 106% of the face value beginning April 1,
2000, declining to 103% in 2001, and 100% in 2002 and 2003, plus accrued
interest.
 
  On May 18, 1998, a portion of the proceeds from the issuance of the New
Senior Notes was used to repurchase the Old Senior Notes. The Company
recognized an extraordinary loss of $19.7 million on repurchase comprising a
premium of $9.8 million and a write-off of $9.9 million of unamortized deferred
financing costs.
 
7. MANDATORILY REDEEMABLE PREFERENCE SHARES
 
  The authorized preference shares consist of 500,000 shares at a liquidation
preference of $1,000 per share. Effective March 25, 1997, 100,000 shares were
issued for $100 million in cash and as of September 30, 1998, nil shares
(109,830 shares as of December 31, 1997) were issued and outstanding.
 
  The holders of preference shares are entitled to receive cumulative,
compounding dividends at an initial annual rate of 14% of the $1,000
liquidation preference per share. If the preference shares are not redeemed on
or prior to April 1, 2001, the annual dividend rate will increase by 0.5% per
annum (the dividend rate payable increases by 2% upon any event of default)
thereafter, subject to a maximum annual dividend rate of 20%. At the option of
GTH, accrued dividends may be paid in cash or paid by issuing additional
preference shares (i.e. pay-in-kind) until April 1, 2002, at which time they
must be paid in cash. However, if the dividend rate exceeds 15% per annum, GTH
may cause dividends in excess of 15% to be paid in additional preference
shares. Dividends paid in additional preference shares are payable on a
quarterly basis and cash dividends are payable on a semi-annual basis. All
dividends declared to date have been paid in additional preference shares. The
preference shares rank senior to all common stock with respect to dividend
rights, rights of redemption or rights on liquidation and senior to any future
preferred stock. The preference shares are non-voting unless GTH fails to pay a
dividend, fails to make a mandatory redemption or upon a change in control,
fails to make an offer to purchase the preference shares at 101%, at which time
the holders of a majority of the preference shares will be entitled to elect
one to two directors. In the event that any preference shares are still
outstanding on April 1, 2001, the holders thereof will receive warrants to
purchase shares of Class A common stock of Old GCL at an exercise price of $.01
per share, up to a maximum of 46,440 shares of Old GCL common stock.
 
  The preference shares have a mandatory redemption on April 1, 2007 at their
liquidation preference. In addition, the preference shares will be redeemed out
of ACL's Excess Cash Flows (as described in Note 5) after repayment of the
Credit Facility and Senior Notes at redemption prices starting at 114% for both
1997 and 1998, declining to 112% in 1999 and 2000, 107% in 2001 and 100%
thereafter. The preference shares can be redeemed, in whole or in part, at the
option of GTH at redemption prices starting at 114% of the liquidation
preference through 2001, declining to 111% in 2002, 108% in 2003, 105% in 2004,
102% in 2005 and 100% thereafter. The outstanding preference shares are
exchangeable, in whole, at the option of GTH for Senior

                          (EXPRESSED IN U.S. DOLLARS)
Subordinated Exchange Notes ("Exchange Notes") issued by ACL at a rate of
$1,000 principal amount of Exchange Notes for each $1,000 of liquidation
preference of preference shares. These Exchange Notes will bear an interest
rate equal to the dividend rate of the preference shares and will have
repayment terms similar to the preference shares described above.
 
  In connection with the issuance of the preference shares, the holders of
preference shares purchased an aggregate of 11,250,000 shares of Old GCL's
Class A common stock for total proceeds of $7.5 million. Additionally, in
connection with the issuance of the preference shares, the initial purchaser of
the preference shares received 19,852,950 shares of Old GCL's Class A common
stock for no additional consideration representing 15% of the aggregate number
of Old GCL's Class A, B and C shares outstanding, after giving effect to the
issuance. The initial purchaser had the right to distribute these Class A
shares to purchasers of the preference shares.  The Company has reflected the
$13,235,000 estimated fair value of the Old GCL's Class A common stock as a
discount in the carrying value of the preference shares.
 
  The fair value of the 19,852,950 shares of Old GCL's Class A common stock
distributed to preference shareholders was based on the $.67 per share paid by
the holders of preference shares for the 11,250,000 Old GCL's Class A shares
purchased for cash.
 
  On June 17, 1998, proceeds from the issuance of the New Senior Notes were
used to redeem the preference shares. The redemption of the preference shares
resulted in a charge against additional paid-in-capital comprised of a $15.9
million redemption premium and $18.2 million of unamortized discount and
issuance cost on the preference shares on the date of the redemption. The
redemption premium and write-off of unamortized discount and issuance costs on
the preference shares were treated as a deduction to arrive at the net loss
applicable to common shareholders in the consolidated statement of operations.
Furthermore, upon the redemption of the preference shares, the warrants
attached to the preference shares expired.
 
  Preference share dividends included the following:

Interest rate swap               The interest rate swap transaction is "zero

                                 rate paid. As the transaction is accounted
                                 for as a hedge against interest rate
                                 fluctuations on the long term debt there is
                                 no carrying value. The fair value is a mid-

  Bermuda does not impose a statutory income tax and consequently the provision
for income taxes recorded relates to income earned where subsidiaries of the
Company have a presence in taxable jurisdictions. There are no significant
temporary differences between accounting and taxable income.
 
  Since the Company has not recognized any income in periods prior to April 1,
1998, no tax provision has been reflected in those periods. Operating losses
incurred in those periods relate almost entirely to non-taxable jurisdictions
and therefore these operating losses cannot be applied to future taxable
earnings of the Company. Therefore the Company has not recorded any deferred
tax asset as a result of such losses in accordance with SFAS 109.
 
10. COMMITMENTS
 
  As of September 30, 1998, ACL was committed under its contract with TSSL for
future construction costs totaling approximately $44 million ($195 million as
of December 31, 1997) and is committed under the OA&M contract with TSSL to
quarterly payments, over the next eight years, totaling approximately $254
million ($263 million as of December 31, 1997).
 
  ACL is committed to paying TSSL commissions ranging from 4% to 7% on revenues
received until 2002, subject to certain reductions. As of September 30, 1998,
Mid Atlantic Crossing Ltd. was committed under its contract with Alcatel
Submarine Networks for future construction costs totaling approximately $221
million and as of September 30, 1998 Pan American Crossing Ltd. was committed

11. FINANCIAL INFORMATION OF GCL CONSOLIDATED, GCH, GUARANTORS AND NON-
GUARANTORS
 
  Old GCL, GCL and certain subsidiaries each provide a guarantee of the New
Senior Notes described in Note 6. Additionally, Global Crossing International,
Inc. ("GCI"), a wholly-owned subsidiary of GCH that provides marketing and
development services to GCL, along with its wholly-owned subsidiaries, also
provide guarantees of the New Senior Notes. All guarantees are full,
unconditional, joint and several. To the extent companies providing a guarantee
have excess cash, dividends or loans of this cash can be made to GCH without
restriction. One of the Non-Guarantors is restricted under its long term debt
agreement from making any dividends or loans to GCH effectively for the
duration of such long term debt agreement. Separate financial statements of
each subsidiary guarantor have not been provided because they would not be
meaningful to investors.
 
  We have presented the Balance Sheets, Statements of Operations and Statements
of Cash Flows for GCL consolidated, GCH, Guarantors and Non-Guarantors as of
and for the nine months ended September 30, 1998 and as of and for the period
from March 19, 1997 (Date of Inception) to December 31, 1997. We have also
included the GCL Consolidated Statements of Changes in Shareholders' Equity for
the periods from March 19, 1997 (Date of Inception) to December 31, 1997 and
for the nine months ended September 30, 1998. In addition, the reconciliation
of the numerator and denominator for the basic and diluted net income (loss)
per share has been presented along with notes to the GCL consolidated financial

         FINANCIAL INFORMATION OF GCL CONSOLIDATED, GCH, GUARANTORS AND
                           NON-GUARANTORS (CONTINUED)
  All footnotes in these GCH consolidated financial statements are applicable
to both GCH and GCL. The footnotes below are applicable to GCL only:
 
(I) OLD GCL COMMON STOCK AND ADDITIONAL PAID-IN-CAPITAL
 
  As discussed in Note 1, on January 21, 1998, Old GCL effected a 100 for 1
stock split of each of the Class A, B, C and D common stock and undesignated
stock and amended the par value of each share of common stock from $.0001 per
share to $.000001 per share. Shares of common stock of Old GCL outstanding have
been restated to reflect the equivalent number of shares of GCL that were
issued in the Old GCL Exchange as discussed in "Note 1". Class A shares, Class
B shares and Class C shares all have voting rights. On March 25, 1997, Old GCL
issued 11,250,000 Class A shares, 50,625,000 Class B shares, 50,625,000 Class C
shares for $.67 per share, resulting in aggregate proceeds of $75 million. As
discussed in Note 7, in addition to the 11,250,000 Class A shares issued to the
preference shareholders for cash, in connection with the issuance of the
preference shares, a total of 19,852,950 Class A shares were distributed to the
initial preference shareholder representing 15% of the aggregate number of
Class A, B and C shares outstanding. In addition, warrants to acquire a maximum
of 46,440 shares of common stock of Old GCL were issued into escrow for the
benefit of the holders of preference shares. All or a portion of the warrants
may be exercised at a price of $.01 per share if the preference shares are
outstanding on April 1, 2001. Effective January 21, 1998, Old GCL authorized
1,000,000,000 of new Class E non-voting shares.
 
  Certain of the Class B shareholders were issued a total of 33,088,200 Class D
shares. Of the $33,750,000 of proceeds received from the issuance of Class B
shares, $2,500,000 was allocated to the Class D shares representing the
estimated fair value of the Class D shares based on an independent valuation.
Class D shares are non-voting shares which carry special preference rights on
the cash distributions made by Old GCL. Class D shareholders will receive 10%
of cash distributions to common shareholders once the internal rate of return
to Class C shareholders exceeds 10%, and then increasing to 20% of cash
distributions to common shareholders once the internal rate of return to Class
C shareholders exceeds 30%. Effective January 21, 1998, Class D share rights
were amended such that Class D shareholders now have the option to convert each
Class D share into one Class E share upon payment to Old GCL of $1.47 per share
or are entitled to a fraction of a Class E share based upon a valuation at the
time of such conversion, together with a warrant to purchase the remaining
fraction of such Class E share at an exercise price based upon such market
valuation. By granting to holders of the Class D shares an option to convert
such shares into Class E shares, the GCL obtained effective assurance that it
could effect a change to a corporate structure in the event of a major equity
event, such as a merger or other business combination or in the event of an IPO
by GCL of its common stock, since the holders of the Class D shares would need
to exercise their options in order to participate directly in benefits of a
merger or acquisition of the GCL or in order to obtain the benefits of any
trading market for the common stock of the GCL; no trading market was expected
to develop for the Class D shares. The grant of the options to Class D
shareholders represents an equity transaction since the GCL granted these
shareholders amended share rights in the form of options with new warrants. As
an equity transaction, the fair value of the option would be recorded as an
increase in additional paid-in-capital and a corresponding charge against
retained earnings, but since the GCL has an accumulated deficit, the charge
would be made against additional paid-in-capital which would have no impact on
the consolidated financial statements. The GCL will account for the new
warrants as an equity transaction on the date the warrants are issued, which is
expected to be the IPO date. The accounting would increase additional paid-in-
capital and a charge to retained earnings to the extent the GCL has retained
earnings on that date, or against additional paid-in-capital if the GCL does
not have retained earnings.

         FINANCIAL INFORMATION OF GCL CONSOLIDATED, GCH, GUARANTORS AND
                           NON-GUARANTORS (CONTINUED)
 
  During the nine months ended September 30, 1998, GCL issued, at a price of
$.67 per share, 450,000 Class B shares and 337,500 Class E shares. Since the
estimated fair value of shares exceeded the issue price, GCL increased stock
related expense and shareholders' equity by $nil and $2,262,679 in the three
and nine months ended September 30, 1998, respectively.
 
(II) STOCK OPTION PLAN AND STOCK RELATED EXPENSE
 
  GCL accounts for stock option grants in accordance with Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"),
and, recognizes compensation expense for stock option grants to the extent that
the estimated fair value of the stock exceeds the exercise price of the option
at the measurement date. The compensation expense is charged against operations
ratably over the vesting period of the options. Disclosures will be made in the
consolidated financial statements of future periods in accordance with
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-
Based Compensation" ("SFAS 123").
 
  On January 21, 1998, GCL adopted the 1998 Stock Incentive Plan ("the Plan")
which grants non-qualified stock options to key officers and employees of the
GCL at the discretion of the Board of Directors. As of September 30, 1998, the
maximum number of options which may be issued under the Plan was 16,607,865 for
the rights to purchase an equivalent number of shares of common stock.
Generally, options vest equally over a period of three years and expire ten
years from the date of grant.
 
  The following table summarizes the transaction of GCL's stock option plans
for the nine months ended September 30, 1998.

  The weighted average remaining life of the options outstanding as of
September 30, 1998 is 9.5 years. During the three month and nine month periods
ended September 30, 1998, no options had expired or were exercised.
 
  During the nine months ended September 30, 1998 the Company entered into an
employment arrangement with a key executive, hired during the third quarter,
and granted him the economic rights to purchase 800,000 shares of common stock
at $4.00 per share. The right to purchase one third of these shares vested
immediately and the balance will vest over two years. The Company recorded the
excess of the fair market value of these rights over the purchase price as
unearned stock compensation in the amount of $14.6 million during the nine
months ended September 30, 1998. The unearned compensation is being recognized
as an expense over the vesting period of the rights.

                           NON-GUARANTORS (CONTINUED)
 
  As of September 30, 1998, GCL recorded $81.7 million of unearned
compensation, relating to the stock option plan plus the economic rights to
purchase common stock granted to a key executive. The unearned compensation is
being recognized as an expense over the vesting period of these options and
economic rights to purchase common stock. GCL recognized $9.7 million of
compensation expense during the three months ended September 30, 1998. During
the nine months ended September 30, 1998, the Company also recorded stock-
related expense of $2.3 million relating to shares issued during this period.
 
  For the nine months ended September 30, 1998, GCL recognized $25.9 million of
stock related compensation relating to its Stock Incentive Plan and $4.9
million for the vested economic rights to purchase common stock. The remaining
$50.9 million of unearned compensation will be recognized as follows: $6.0
million in the fourth quarter of 1998, $24.1 million in 1999, $17.1 million in
2000 and $3.7 million in 2001.
 
  No compensation expense was recognized for the options granted on January 21,
1998, August 9, 1998 and September 18, 1998 since the estimated fair value of
the stock, on that date did not exceed the exercise price.
 
  As permitted by SFAS 123, the GCL has chosen to account for employee stock
options under APB 25 and is recognizing compensation expense over the vesting
period to the extent that the estimated fair value of the stock on the date the
options were granted exceeded the exercise price on the dates of grant. Had
compensation cost for the GCL's stock-based compensation plans been determined
consistent with the SFAS 123 fair value approach, the impact on the GCL's loss
applicable to common shareholders and loss per share would be as follows:

estimated fair value of the options granted on January 21, April 3, June 12,
1998, August 9, 1998 and September 18, 1998 were $0.49, $11.40, $15.90, $6.38

12. RELATED PARTY TRANSACTIONS
 
 Advisory Services Agreement ("ASA")
 
  GCL has entered into the ASA with PCG Telecom, an affiliate of Pacific
Capital Group, Inc. ("PCG") which is a shareholder of GCL. Under the ASA, PCG
Telecom provides ACL with advice in respect of the development and maintenance
of AC-1, development and implementation of marketing and pricing strategies and
the preparation of business plans and budgets. As compensation for its advisory
services, PCG Telecom

receives a 2% fee on the gross revenues of the Company, subject to certain
restrictions, with the first such payment occurring at the System RFS date.
Advances on fees payable under the ASA are being paid to PCG Telecom at a rate
of 1% on signed CPAs and Backhaul CPAs until the System RFS date and are
secured by amounts payable under the ASA. Fees paid under the ASA to PCG
Telecom are shared amongst ULLICO, Inc., PCG, CIBC, and Messrs. Winnick, Cook,
Brown, Lee and Porter, all of whom are shareholders of GCL. The Advisory
Service Agreements ("ASA") which were terminated effective on June 30, 1998 had
terms of 25 years subject to termination, however, the ASA did not contain
provisions regarding cancellation fees or liquidated damages in the event of
termination or breach. GCL acquired the rights under the ASA on behalf of the
Company and contributed such rights to the Company. This transaction was
recorded in the consolidated financial statements as an increase in additional
paid-in-capital and a charge against the statement of operations in the amount
of $137.7 million. The $137.7 million is comprised of a $135 million settlement
of the fees that would have been payable and the cancellation of approximately
$2.7 million owed to the Company under a related advance agreement. The $135
million amount was calculated by applying the 2% advisory services fee to
projected future revenues and discounting the amount relating to AC-1 revenues
by 12% and the amount relating to all other system's revenues by 15%. The
result of this calculation was $155.5 million, which amount was subsequently
reduced to $135 million. Both the discount rates and the ultimate valuation
were determined as a result of a negotiation process including a disinterested
director of the Company and the various persons entitled to fees under the ASA.
The Company has obtained a fairness opinion from an independent financial
advisor in connection with this transaction.
 
 PCG Warrants
 
  Prior to January 21, 1998, PCG and its affiliates had commenced development
of systems other than AC-1, namely PC-1, MAC and PAC. Through January 21, 1998,
such development included assembling a management team, negotiating with
potential suppliers, partners, financing sources, obtaining preliminary market
and feasibility studies and developing technical requirements. On January 21,
1998, the Board determined that it was in the Company's best interests to
pursue these new systems, obtain the results of the work and the employees then
within the scope of activity of PCG and broaden the goals, objectives and
business plan of the Company. In consideration of PCG transferring the results
of its activities and becoming

limited in its future activities in fiber optic telecommunications other than
through GCL, the Board approved and the shareholders subsequently approved the
transaction whereby PCG received approximately $7 million representing PCG's
costs related thereto and Old GCL entered into a warrant agreement ("PCG
Warrants") under which PCG was issued three separate warrants permitting PCG to
purchase (i) 9,226,592 of Old GCL's Class B shares for an aggregate price of
$50,000,000; (ii) an additional 4,613,297 of Old GCL's Class B shares for an
aggregate price of $31,250,000; and (iii) an additional 4,613,297 of Old GCL's
Class B shares for an aggregate price of $37,500,000. The PCG Warrants were
granted in exchange for the rights to commence the development of the new
projects that previously had been under development by an affiliate of PCG.
 
  These warrants are intended to entitle PCG to acquire, in addition to their
existing ownership, 10% of the capital stock of GCL, as of the date these
warrants were issued. Exercise of these warrants is contingent upon (i) an IPO
of shares of Old GCL (or any successor thereto), underwritten by an investment
banking firm of national reputation (as determined by a majority of the Board
of Directors of Old GCL) from which Old GCL shall have received at least
$50,000,000 in net proceeds, (ii) the investment by Old GCL in the aggregate of
at least $500,000,000 of Net Attributable Capital (as defined below) in cable
systems other than AC-1 and (iii) the generation in the aggregate by cable
systems other than AC-1 of at least $100,000,000 in Net Attributable Revenues
(as defined below). For purposes of the PCG Warrant Agreement, with respect to
any cable system, "Net Attributable Capital" means the aggregate debt and
equity capitalization of such system multiplied by the percentage ownership of
Old GCL (directly or indirectly) in such system, and "Net Attributable
Revenues" means the net revenues of such system multiplied by the percentage
ownership interest of Old GCL (directly or indirectly) in such system. No
accounting was made for the PCG Warrants at the time of issuance on the basis
that it was indeterminable when the conditions described above would be met.
 
  In June, 1998, the Board of Directors amended the terms of the PCG Warrants
so that the PCG Warrants will become exercisable upon the successful completion
of the IPO and eliminated conditions (ii) and (iii) above. Further to this
amendment, the Board of Directors also amended the terms of the PCG Warrants to
give each holder the option to convert each share under warrant into a fraction
of a Class B share based upon the ratio of the current per share valuation at
the time of conversion less the per share exercise price of the warrant divided
by the current per share valuation at the time of conversion multiplied by the
18,453,185 shares available under the PCG Warrants, together with a new warrant
("New PCG Warrants") to purchase the remaining fraction of such Class B share
at an exercise price equal to the current per share valuation. Prior to the
IPO, it is expected that the holders of the PCG Warrants will exercise their
warrants to acquire Class B shares by way of the cashless conversion and the
New PCG Warrants will be issued with an exercise price based on the per share
valuation at the conversion date.
 
  The Company had accounted for the PCG Warrants by assuming the cashless
conversion took place as of June 30, 1998 using the current estimated per share
valuation at the expected conversion date, multiplied by the number of Class B
shares estimated to be converted in exchange for the PCG Warrants. The value
attributed to the PCG Warrants as described below was contributed to the
Company by the Company's parent GCL. The resulting value under this calculation
is approximately $213.3 million which has been allocated to the new systems
acquired in exchange for the PCG Warrants. In connection with the formation of
PCL, the Company agreed to make available to PCL the consideration received by
the Company in connection with the grant of the PCG Warrants, in addition to
the $231 million cash investment made by the Company. See Note 3.

                          (EXPRESSED IN U.S. DOLLARS)
Therefore, the Company recorded an increase in its investment in PCL in the
amount of approximately $126.5 million and an increase in construction in
progress for PAC and MAC in the amounts of approximately $49.9 million and
$36.9 million, respectively, with a corresponding increase of $213.3 million in
additional paid in capital. The $213.3 million was allocated on a pro rata
basis to the three projects according to the estimated cost of each system. The
Company's accounting for the PCG Warrants is pursuant to Emerging Issues Task
Force 96-18, "Accounting for Equity Instruments with Variable Terms that are
Issued for Consideration other than Employee Services under FASB Statement No.
123" ("EITF 96-18"). Under EITF 96-18, the fair value of equity instruments
issued for consideration other than employee services should be measured using
the stock price or other measurement assumptions as of the date at which a firm
commitment for performance level has been reached. The Company has recorded the
estimated value of the PCG Warrants as of June 30, 1998, since the IPO was
probable at that date. The $213.3 million value attributed to the PCG Warrants
as of June 30, 1998 was adjusted to the actual value of $275.3 million on the
date of the IPO based upon the $19 price per share.
 
  The Company gave accounting recognition for the New PCG Warrants on the date
these warrants were issued, which was the date of the IPO. The Company valued
of each of the New PCG Warrants at $6.95 based on an independent valuation
based on the IPO price of $19 per share. The New PCG Warrants had a total value
of approximately $43 million. The Company recorded the actual value of the New
PCG Warrants in a manner similar to that described above whereby the total
value was allocated to the investment in PCL, MAC and PAC based on their
relative total contract costs.
 
 Other transactions
 
  $7,250,000 in fees were paid to PCG and certain of its key executives, who
are shareholders of GCL, and another shareholder for services provided in
respect of obtaining the Credit Facility, Senior Notes and preference share
financing. Of the fees paid, $5,523,775 was allocated to the Credit Facility
and Senior Notes and recorded as deferred finance costs, $986,725 was allocated
to the preference shares and recorded as a reduction in the carrying value of
the preference shares and $739,500 was recorded as common stock issuance costs
and is included in the approximately $1.3 million which is reflected as a
reduction in additional paid-in-capital.
 
  GCL has paid CIBC approximately $25 million in fees related to the financing
obtained under the Old Senior Notes, Credit Facility, and the issuance of
preference shares. Of the fees incurred, approximately $6.2 million related to
underwriting and commitment fees pertaining to the issuance of the preference
shares and were recorded as a reduction in the carrying value of the preference
shares, approximately $9.2 million related to underwriting, commitment and
advisory fees in connection with the issuance of the Senior Notes and
approximately $9.6 million related to fees associated with obtaining the Credit
Facility which were recorded as deferred finance costs. CIBC is a member of the
syndicate funding the Credit Facility under which the Company has borrowings of
$365,140,294 ($162,325,000 as of December 31, 1997), as of September 30, 1998
and has been paid interest and other related fees in the amount of
approximately $21 million as of September 30, 1998 ($4.2 million as of December
31, 1997). CIBC is also one of the initial purchasers of the New Senior Notes
and received a $5,817,425 commitment and structuring fee as well as portion of
the $24,750,000 underwriting fee paid to the initial purchasers. CIBC was also
one of the underwriters of the Company's IPO and received a portion of the
approximate $25 million underwriting fee paid to the underwriters.

  On April 7, 1998, the Company signed a CPA with Worldport Communications,
Inc. ("Worldport"), to acquire capacity on AC-1. This transaction occurred in
the ordinary course of business of the Company and on terms and conditions no
less favorable to the Company than in its other CPAs. Certain officers and
directors of the Company, have direct or indirect equity ownership positions in
Worldport, aggregating approximately 10% of the current common stock of
Worldport.
 
  GCL purchased all common shares owned by Telecommunications Development
Corporation ("TDC") in the Company in exchange for 150,000 fewer shares of
newly issued common shares based upon the per share value at the repurchase
date. The transaction benefited GCL since 150,000 fewer shares were outstanding
after the repurchase without any cost to GCL. The transaction was accounted for
as the acquisition of treasury stock and will be recorded at the fair value of
the consideration given.

                                     technologies employ a sequence 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

 Multimedia:                         The electronic conversation between two or
                                      more people or groups of people in
                                      different places using two or more types
                                      of digitally integrated communication for
                                      voice, sound, text, data, graphics,
                                      video, image or presence at the same
                                      time. Applications include conferencing,
                                      presentations, training, referencing,
                                      games, etc.

 Multiplexing:                       An electronic or optical process that
                                      combines two or more lower bandwidth
                                      transmissions into one higher bandwidth
                                      signal by splitting the total available
                                      bandwidth into narrower bands (frequency
                                      division) or by allotting a common
                                      channel to several transmitting sources
                                      one at a time in sequence (time
                                      division).

 Multipoint:                         Pertaining or referring to a
                                      communications line to which three or
                                      more stations are connected. It implies
                                      that the line physically extends from one
                                      station to another until all are
                                      connected.

 Optical Fibers:                     Thin filaments of glass through which
                                      light beams are transmitted. Enormous
                                      capacity, low-cost, low-power
                                      consumption, small space, lite-weight,
                                      insensitivity to electromagnetic
                                      interference characterize this transport
                                      media.

 PTTs (Post, Telephone and
  Telegraph
  companies):                        International telecommunications carriers
                                      which are generally under the control of
                                      the government in a country that has not
                                      yet privatized its telecommunications
                                      markets.

 Repeater:                           1. Equipment that receives a low-power
                                        signal, possibly converting it from
                                        light to electrical form, amplifying it
                                        or retiming and reconstructing it for
                                        transmission. It may need to be
                                        reconverted to light for retransmission.
                                     2. An optoelectrical device used at each
                                        end and occasionally at intermediate
                                        points of exceptionally long fiber-optic
                                        span. Optical input is converted to
                                        electrical form to restore a clean
                                        signal, which drives lasers that fully
                                        restores the optical signal at the
                                        original signal strength.

 Route Kilometers:                   The number of route kilometers installed.

 RFS (Ready for Service):            The data of provisional acceptance or
                                      commercial service of a cable system.

 STM (Synchronous Transfer Mode):    New term for traditional TDM switching to
                                      distinguish it from ATM.

 STM-1:                              The largest standard circuit unit of
                                      capacity, which consists of 155,500 Kbps
                                      (equal to 155 Mbps). Thus, each Gbps
                                      contains enough capacity for 6.4 STM-1
                                      circuits. While capacity is sold to the
                                      largest telecommunications companies in
                                      minimum investment units equal to one
                                      STM-1 unit, most telecommunications
                                      companies buy smaller units at a price
                                      higher than the equivalent STM-1 price.

 Wavelength:                        The distance between two crests of a signal
                                     or a carrier and is measured in terms of
                                     meters, millimeters, nanometers, etc. In
                                     lightwave applications, because of the
                                     extremely high frequencies, wavelength is
                                     measured in nanometers.

 xDSL:                              A term referring to a variety of new

                                     of these varieties are asymmetric with
                                     different data rates in the downstream and
                                     upstream directions. Others are symmetric.
                                     Downstream speeds range from 384 Kbps (or
                                     "SDSL") to 1.5-8 Mbps (or "ADSL").

ITEM 22. UNDERTAKINGS.
 
  (a) Insofar as indemnification for liabilities arising under the Securities
Act 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 Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director,
 
                                      II-2
<PAGE>
 
officer or controlling person of the registrant in the successful defense of
any action, suit or proceedings) 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 indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
  (b) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through
the date of responding to the request.
 
  (c) The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective Amendment to this registration statement:
 
      (i) to include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii) to reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20 percent change
    in the maximum aggregate offering price set forth in the "Calculation
    of Registration Fee" table in the effective registration statement; and
 
      (iii) to include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement;
 
    (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering; and
 
    (4) To supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of an included in the registration statement when
  it became effective.
 
    (5) That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this registration
  statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c) the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form.
 
    (6) That every prospectus (i) that is filed pursuant to paragraph (5)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415, will be filed as a part of an amendment to
  the registration statement and will not be used until such amendment is
  effective, and that, for purposes of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

                                  SHARE RIGHTS
                                        

3.   Subject to any special rights conferred on the holders of any share or
     class of shares, any share in the Company may be issued with or have
     attached thereto such preferred, deferred, qualified or other special
     rights or such restrictions, whether in regard to dividend, voting, return
     of capital or otherwise, as the Company may by Resolution determine or, if
     there has not been any such determination or so far as the same shall not
     make specific provision, as the Board may determine.


4.   (1)  Subject to the Companies Acts, any preference shares may, with
          the sanction of a resolution of the Board, be issued on terms:

          (a)  that they are to be redeemed on the happening of a specified
               event or on a given date; and/or,

          (b)  that they are liable to be redeemed at the option of the Company;

          (c)  if authorised by the memorandum/Incorporating act of the Company,
               that they are liable to be redeemed at the option of the holder.

          The terms and manner of redemption shall be provided for in such
          resolution of the Board and shall be attached to but shall not form
          part of these Bye-Laws.

3
<PAGE>
 
     (2)  The Board may, at its discretion and without the sanction of a
          Resolution authorise the purchase by the Company of its own shares
          upon such terms as the Board may in its discretion determine PROVIDED
          ALWAYS that such purchase is effected in accordance with the
          provisions of the Companies Acts.


                             MODIFICATION OF RIGHTS
                                        

5.   Subject to the Companies Acts, all or any of the special rights for the
     time being attached to any class of shares for the time being issued may
     from time to time (whether or not the Company is being wound up) be altered
     or abrogated with the consent in writing of the holders of not less than
     seventy five percent of the issued shares of that class or with the
     sanction of a resolution passed at a separate general meeting of the
     holders of such shares voting in person or by proxy.  To any such separate
     general meeting, all the provisions of these Bye-Laws as to general
     meetings of the Company shall mutatis mutandis apply, but so that the
     necessary quorum shall be two or more persons holding or representing by
     proxy any of the shares of the relevant class, that every holder of shares
     of the relevant class shall be entitled on a poll to one vote for every
     such share held by him and that any holder of shares of the relevant class
     present in person or by proxy may demand a poll; provided, however, that if
     the Company or a class of Shareholders shall have only one Shareholder, one
     Shareholder present in person or by proxy shall constitute the necessary
     quorum.

6.   The special rights conferred upon the holders of any shares or class of
     shares shall not, unless otherwise expressly provided in the rights
     attaching to or the terms of issue of such shares, be deemed to be altered
     by the creation or issue of further shares ranking pari passu therewith.

                                    SHARES
                                        

7.   Subject to the provisions of these Bye-Laws, the unissued shares of the
     Company (whether forming part of the original capital or any increased
     capital) shall be at the disposal of the Board, which may offer, allot,
     grant options over or otherwise dispose of them to such persons, at such
     times and for such consideration and upon such terms and conditions as the
     Board may determine.

8.   The Board may in connection with the issue of any shares exercise all
     powers of paying commission and brokerage conferred or permitted by law.

9.   Except as ordered by a court of competent jurisdiction or as required by
     law, no person shall be recognised by the Company as holding any share upon
     trust and the Company shall not be bound by or required in any way to
     recognise (even when having notice thereof) any equitable, contingent,
     future or partial interest in any share or any interest in any fractional
     part of a share or (except only as otherwise provided in these Bye-Laws, or
     by law) any other right in respect of any share except an absolute right to
     the entirety thereof in the registered holder.


                                  CERTIFICATES


10.  The preparation, issue and delivery of certificates shall be governed by
     the Companies Acts.  In the case of a share held jointly by several
     persons, delivery of a certificate to one of several joint holders shall be
     sufficient delivery to all.

11.  If a share certificate is defaced, lost or destroyed it may be replaced
     without fee 

5
<PAGE>
 
     but on such terms (if any) as to evidence and indemnity and to payment
     of the costs and out of pocket expenses of the Company in investigating
     such evidence and preparing such indemnity as the Board may think fit and,
     in case of defacement, on delivery of the old certificate to the Company.

12.  All certificates for share or loan capital or other securities of the
     Company (other than letters of allotment, scrip certificates and other like
     documents) shall, except to the extent that the terms and conditions for
     the time being relating thereto otherwise provide, be issued under the
     Seal. The Board may by resolution determine, either generally or in any
     particular case, that any signatures on any such certificates need not be
     autographic but may be affixed to such certificates by some mechanical
     means or may be printed thereon or that such certificates need not be
     signed by any persons.

                                      LIEN
                                        

13.  The Company shall have a first and paramount lien on every share (not being
     a fully paid share) for all moneys, whether presently payable or not,
     called or payable, at a date fixed by or in accordance with the terms of
     issue of such share in respect of such share, and the Company shall also
     have a first and paramount lien on every share (other than a fully paid
     share) standing registered in the name of a Shareholder, whether singly or
     jointly with any other person, for all the debts and liabilities of such
     Shareholder or his estate to the Company, whether the same shall have been
     incurred before or after notice to the Company of any interest of any
     person other than such Shareholder, and whether the time for the payment or
     discharge of the same shall have actually arrived or not, and
     notwithstanding that the same are joint debts or liabilities of such

6
<PAGE>
 
     Shareholder or his estate and any other person, whether a Shareholder or
     not.  The Company's lien on a share shall extend to all dividends payable
     thereon.  The Board may at any time, either generally or in any particular
     case, waive any lien that has arisen or declare any share to be wholly or
     in part exempt from the provisions of this Bye-Law.

14.  The Company may sell, in such manner as the Board may think fit, any share
     on which the Company has a lien but no sale shall be made unless some sum
     in respect of which the lien exists is presently payable nor until the
     expiration of fourteen days after a notice in writing, stating and
     demanding payment of the sum presently payable and giving notice of the
     intention to sell in default of such payment, has been served on the holder
     for the time being of the share.

15.  The net proceeds of sale by the Company of any shares on which it has a
     lien shall be applied in or towards payment or discharge of the debt or
     liability in respect of which the lien exists so far as the same is
     presently payable, and any residue shall (subject to a like lien for debts
     or liabilities not presently payable as existed upon the share prior to the
     sale) be paid to the person who was the holder of the share immediately
     before such sale.  For giving effect to any such sale the Board may
     authorise some person to transfer the share sold to the purchaser thereof.
     The purchaser shall be registered as the holder of the share and he shall
     not be bound to see to the application of the purchase money, nor shall his
     title to the share be affected by any irregularity or invalidity in the
     proceedings relating to the sale.


                                CALLS ON SHARES

7
<PAGE>
 
16.  The Board may from time to time make calls upon the Shareholders in respect
     of any moneys unpaid on their shares (whether on account of the par value
     of the shares or by way of premium) and not by the terms of issue thereof
     made payable at a date fixed by or in accordance with such terms of issue,
     and each Shareholder shall (subject to the Company serving upon him at
     least fourteen days notice specifying the time or times and place of
     payment) pay to the Company at the time or times and place so specified the
     amount called on his shares. A call may be revoked or postponed as the
     Board may determine.

17.  A call may be made payable by instalments and shall be deemed to have been
     made at the time when the resolution of the Board authorising the call was
     passed.

18.  The joint holders of a share shall be jointly and severally liable to pay
     all calls in respect thereof.

19.  If a sum called in respect of the share shall not be paid before or on the
     day appointed for payment thereof the person from whom the sum is due shall
     pay interest on the sum from the day appointed for the payment thereof to
     the time of actual payment at such rate as the Board may determine, but the
     Board shall be at liberty to waive payment of such interest wholly or in
     part.

20.  Any sum which, by the terms of issue of a share, becomes payable on
     allotment or at any date fixed by or in accordance with such terms of
     issue, whether on account of the nominal amount of the share or by way of
     premium, shall for all the purposes of these Bye-Laws be deemed to be a
     call duly made, notified and payable on the date on which, by the terms of
     issue, the same becomes payable and, in case of non-payment, all the

8
<PAGE>
 
     relevant provisions of these Bye-Laws as to payment of interest, forfeiture
     or otherwise shall apply as if such sum had become payable by virtue of a
     call duly made and notified.

21.  The Board may on the issue of shares differentiate between the allottees or
     holders as to the amount of calls to be paid and the times of payment.


                              FORFEITURE OF SHARES
                                        

22.  If a Shareholder fails to pay any call or instalment of a call on the day
     appointed for payment thereof, the Board may at any time thereafter during
     such time as any part of such call or instalment remains unpaid serve a
     notice on him requiring payment of so much of the call or instalment as is
     unpaid, together with any interest which may have accrued.

23.  The notice shall name a further day (not being less than 14 days from the
     date of the notice) on or before which, and the place where, the payment
     required by the notice is to be made and shall state that, in the event of
     non-payment on or before the day and at the place appointed, the shares in
     respect of which such call is made or instalment is payable will be liable
     to be forfeited.  The Board may accept the surrender of any share liable to
     be forfeited hereunder and, in such case, references in these Bye-Laws to
     forfeiture shall include surrender.

24.  If the requirements of any such notice as aforesaid are not complied with,
     any share in respect of which such notice has been given may at any time
     thereafter, before payment of all calls or instalments and interest due in
     respect thereof has been made, be forfeited by a resolution of the Board to
     that effect.  Such forfeiture shall include all dividends declared in
     respect of the forfeited shares and not actually paid before the
     forfeiture.

9
<PAGE>
 
25.  When any share has been forfeited, notice of the forfeiture shall be served
     upon the person who was before forfeiture the holder of the share; but no
     forfeiture shall be in any manner invalidated by any omission or neglect to
     give such notice as aforesaid.

26.  A forfeited share shall be deemed to be the property of the Company and may
     be sold, re-offered or otherwise disposed of either to the person who was,
     before forfeiture, the holder thereof or entitled thereto or to any other
     person upon such terms and in such manner as the Board shall think fit, and
     at any time before a sale, re-allotment or disposition the forfeiture may
     be cancelled on such terms as the Board may think fit.

27.  A person whose shares have been forfeited shall thereupon cease to be a
     Shareholder in respect of the forfeited shares but shall, notwithstanding
     the forfeiture, remain liable to pay to the Company all moneys which at the
     date of forfeiture were presently payable by him to the Company in respect
     of the shares with interest thereon at such rate as the Board may determine
     from the date of forfeiture until payment, and the Company may enforce
     payment without being under any obligation to make any allowance for the
     value of the shares forfeited.

28.  An affidavit in writing that the deponent is a Director of the Company or
     the Secretary and that a share has been duly forfeited on the date stated
     in the affidavit shall be conclusive evidence of the facts therein stated
     as against all persons claiming to be entitled to the share.  The Company
     may receive the consideration (if any) given for the share on the sale, re-
     allotment or disposition thereof and the Board may authorise some person 

10
<PAGE>
 
     to transfer the share to the person to whom the same is sold, re-allotted
     or disposed of, and he shall thereupon be registered as the holder of the
     share and shall not be bound to see to the application of the purchase
     money (if any) nor shall his title to the share be affected by any
     irregularity or invalidity in the proceedings relating to the forfeiture,
     sale, re-allotment or disposal of the share.


                            REGISTER OF SHAREHOLDERS
                                        

29.  The Secretary shall establish and maintain the Register at the Registered
     Office in the manner prescribed by the Companies Acts.  Unless the Board
     otherwise determines, the Register shall be open to inspection in the
     manner prescribed by the Companies Acts between 10.00 a.m. and 12.00 noon
     on every working day.  Unless the Board so determines, no Shareholder or
     intending Shareholder shall be entitled to have entered in the Register any
     indication of any trust or any equitable, contingent, future or partial
     interest in any share or any interest in any fractional part of a share and
     if any such entry exists or is permitted by the Board it shall not be
     deemed to abrogate any of the provisions of Bye-Law 9.


                       REGISTER OF DIRECTORS AND OFFICERS
                                        

30.  The Secretary shall establish and maintain a register of the Directors and
     Officers of the Company as required by the Companies Acts.  The register of
     Directors and Officers shall be open to inspection in the manner prescribed
     by the Companies Acts between 10:00 a.m. and 12:00 noon on every working
     day.


                               TRANSFER OF SHARES

11
<PAGE>
 
31.  Subject to the Companies Acts and to such of the restrictions contained in
     these Bye-Laws as may be applicable, any Shareholder may transfer all or
     any of his shares by an instrument of transfer in the usual common form or
     in any other form which the Board may approve.


32.  The instrument of transfer of a share shall be signed by or on behalf of
     the transferor and where any share is not fully-paid, the transferee and
     the transferor shall be deemed to remain the holder of the share until the
     name of the transferee is entered in the Register in respect thereof. All
     instruments of transfer when registered may be retained by the Company. The
     Board may, in its absolute discretion and without assigning any reason
     therefor, decline to register any transfer of any share which is not a
     fully-paid share. The Board may also decline to register any transfer
     unless:-


     (1)  the instrument of transfer is duly stamped and lodged with the
          Company, accompanied by the certificate for the shares to which it
          relates, and such other evidence as the Board may reasonably require
          to show the right of the transferor to make the transfer,


     (2)  the instrument of transfer is in respect of only one class of share,


     (3)  where applicable, the permission of the Bermuda Monetary Authority
          with respect thereto has been obtained.


     Subject to any directions of the Board from time to time in force, the
     Secretary may exercise the powers and discretions of the Board under this
     Bye-Law and Bye-Laws 31 and 33.


33.  If the Board declines to register a transfer it shall, within three months
     after the date on which the instrument of transfer was lodged, send to the
     transferee notice of such refusal.

12
<PAGE>
 
34.  No fee shall be charged by the Company for registering any transfer,
     probate, letters of administration, certificate of death or marriage, power
     of attorney, distringas or stop notice, order of court or other instrument
     relating to or affecting the title to any share, or otherwise making an
     entry in the Register relating to any share.


                             TRANSMISSION OF SHARES
                                        

35.  In the case of the death of a Shareholder, the survivor or survivors, where
     the deceased was a joint holder, and the estate representative, where he
     was sole holder, shall be the only person recognised by the Company as
     having any title to his shares; but nothing herein contained shall release
     the estate of a deceased holder (whether the sole or joint) from any
     liability in respect of any share held by him solely or jointly with other
     persons.  For the purpose of this Bye-Law, estate representative means the
     person to whom probate or letters of administration has or have been
     granted in Bermuda or, failing any such person, such other person as the
     Board may in its absolute discretion determine to be the person recognised
     by the Company for the purpose of this Bye-Law.


36.  Any person becoming entitled to a share in consequence of the death of a
     Shareholder or otherwise by operation of applicable law may, subject as
     hereafter provided and upon such evidence being produced as may from time
     to time be required by the Board as to his entitlement, either be
     registered himself as the holder of the share or elect to have some person
     nominated by him registered as the transferee thereof.  If the person so
     becoming entitled elects to be registered himself, he shall deliver or send
     to the Company a notice in writing signed by him stating that he so elects.

13
<PAGE>
 
     If he shall elect to have his nominee registered, he shall signify his
     election by signing an instrument of transfer of such share in favour of
     his nominee.  All the limitations, restrictions and provisions of these
     Bye-Laws relating to the right to transfer and the registration of transfer
     of shares shall be applicable to any such notice or instrument of transfer
     as aforesaid as if the death of the Shareholder or other event giving rise
     to the transmission had not occurred and the notice or instrument of
     transfer was an instrument of transfer signed by such Shareholder.

37.  A person becoming entitled to a share in consequence of the death of a
     Shareholder or otherwise by operation of applicable law shall (upon such
     evidence being produced as may from time to time be required by the Board
     as to his entitlement) be entitled to receive and may give a discharge for
     any dividends or other moneys payable in respect of the share, but he shall
     not be entitled in respect of the share to receive notices of or to attend
     or vote at general meetings of the Company or, save as aforesaid, to
     exercise in respect of the share any of the rights or privileges of a
     Shareholder until he shall have become registered as the holder thereof.
     The Board may at any time give notice requiring such person to elect either
     to be registered himself or to transfer the share and, if the notice is not
     complied with within sixty days, the Board may thereafter withhold payment
     of all dividends and other moneys payable in respect of the shares until
     the requirements of the notice have been complied with.

38.  Subject to any directions of the Board from time to time in force, the
     Secretary may exercise the powers and discretions of the Board under Bye-
     Laws 35, 36 and 37.

                              INCREASE OF CAPITAL

14

<PAGE>
 
                                        

39.  The Company may from time to time increase its capital by such sum to be
     divided into shares of such par value as the Company by Resolution shall
     prescribe.


40.  The Company may, by the Resolution increasing the capital, direct that the
     new shares or any of them shall be offered in the first instance either at
     par or at a premium or (subject to the provisions of the Companies Acts) at
     a discount to all the holders for the time being of shares of any class or
     classes 


     in proportion to the number of such shares held by them respectively or
     make any other provision as to the issue of the new shares.


41.  The new shares shall be subject to all the provisions of these Bye-Laws
     with reference to lien, the payment of calls, forfeiture, transfer,
     transmission and otherwise.


                             ALTERATION OF CAPITAL
                                        

42.  The Company may from time to time by Resolution:-

     (1)  divide its shares into several classes and attach thereto respectively
          any preferential, deferred, qualified or special rights, privileges or
          conditions;

     (2)  consolidate and divide all or any of its share capital into shares of
          larger par value than its existing shares;

     (3)  sub-divide its shares or any of them into shares of smaller par value
          than is fixed by its memorandum, so, however, that in the sub-division
          the proportion between the amount paid and the amount, if any, unpaid
          on each reduced share shall be the same as it was in the 

15
<PAGE>
 
          case of the share from which the reduced share is derived;

     (4)  make provision for the issue and allotment of shares which do not
          carry any voting rights;

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

     (6)  change the currency denomination of its share capital.

     Where any difficulty arises in regard to any division, consolidation, or
     sub-division under this Bye-Law, the Board may settle the same as it thinks
     expedient and, in particular, may arrange for the sale of the shares
     representing fractions and the distribution of the net proceeds of sale in
     due proportion amongst the Shareholders who would have been entitled to the
     fractions, and for this purpose the Board may authorise some person to
     transfer the shares representing fractions to the purchaser thereof, who
     shall not be bound to see to the application of the purchase money nor
     shall his title to the shares be affected by any irregularity or invalidity
     in the proceedings relating to the sale.

43.  Subject to the Companies Acts and to any confirmation or consent required
     by law or these Bye-Laws, the Company may by Resolution from time to time
     convert any preference shares into redeemable preference shares.


                              REDUCTION OF CAPITAL
                                        

44.  Subject to the Companies Acts, its memorandum and any confirmation or
     consent required by law or these Bye-Laws, the Company may from time

16
<PAGE>
 
     to time by Resolution authorise the reduction of its issued share capital
     or any share premium or contributed surplus account in any manner.

45.  In relation to any such reduction, the Company may by Resolution determine
     the terms upon which such reduction is to be effected including in the case
     of a reduction of part only of a class of shares, those shares to be
     affected.


                    GENERAL MEETINGS AND WRITTEN RESOLUTIONS
                                        

46.  (1)  The Board shall convene and the Company shall hold general meetings as
          Annual General Meetings in accordance with the requirements of the
          Companies Acts at such times and places as the Board shall appoint.
          The Board may, whenever it thinks fit, and shall, when required by the
          Companies Acts, convene general meetings other than Annual General
          Meetings which shall be called Special General Meetings.

     (2)  Except in the case of the removal of auditors and Directors, anything
          which may be done by resolution of the Company in general meeting or
          by resolution of a meeting of any class of the Shareholders of the
          Company may, without a meeting and without any previous notice being
          required, be done by resolution in writing, signed by all of the
          Shareholders or their proxies, or in the case of a Shareholder that is
          a corporation (whether or not a company within the meaning of the
          Companies Acts), on behalf of, all the Shareholders of the Company,
          or any class thereof, in as many counterparts as may be necessary.

     (3)  For the purposes of this Bye-Law, the date of the resolution in
          writing is the date when the resolution is signed by, or in the case

17
<PAGE>
 
          of a Shareholder that is a corporation (whether or not a company
          within the meaning of the Companies Acts), on behalf of, the last
          Shareholder to sign and any reference in any enactment to the date of
          passing of a Resolution is, in relation to a resolution in writing
          made in accordance with this section, a reference to such date.

     (4)  A resolution in writing made in accordance with this Bye-Law is as
          valid as if it had been passed by the Company in general meeting or,
          if applicable, by a meeting of the relevant class of Shareholders of
          the Company, as the case may be.  A resolution in writing made in
          accordance with this section shall constitute minutes for the purposes
          of the Companies Acts and these Bye-Laws.




                           NOTICE OF GENERAL MEETINGS
                                        
47.  An Annual General Meeting shall be called by not less than   5    days
     notice in writing and a Special General Meeting shall be called by not less
     than  5     days notice in writing.  The notice shall be exclusive of the
     day on which it is served or deemed to be served and of the day for which
     it is given, and shall specify the place, day and time of the meeting, and,
     the nature of the business to be considered.  Notice of every general
     meeting shall be given in any manner permitted by Bye-Laws 120 and 121 to
     all Shareholders other than such as, under the provisions of these Bye-Laws
     or the terms of issue of the shares they hold, are not entitled to receive
     such notice from the Company and to any Director or Resident 

18
<PAGE>
 
     Representative who or which has delivered a written notice upon the
     Registered Office requiring that such notice be sent to him or it.
     Notwithstanding that a meeting of the Company is called by shorter notice
     than that specified in this Bye-Law, it shall be deemed to have been duly
     called if it is so agreed:-

     (1)  in the case of a meeting called as an Annual General Meeting, by all
          the Shareholders entitled to attend and vote thereat;

     (2)  in the case of any other meeting, by a majority in number of the
          Shareholders having the right to attend and vote at the meeting, being
          a majority together holding not less than 95 percent in nominal value
          of the shares giving that right.


48.  The accidental omission to give notice of a meeting or (in cases where
     instruments of proxy are sent out with the notice) the accidental omission
     to send such instrument of proxy to, or the non-receipt of notice of a
     meeting or such instrument of proxy by, any person entitled to receive such
     notice shall not invalidate the proceedings at that meeting.



                        PROCEEDINGS AT GENERAL MEETINGS
                                        

49.  No business shall be transacted at any general meeting unless a quorum is
     present when the meeting proceeds to business, but the absence of a quorum
     shall not preclude the appointment, choice or election of a chairman which
     shall not be treated as part of the business of the meeting.  Save as
     otherwise provided by these Bye-Laws, at least two Shareholders present in
     person or by proxy and entitled to vote shall be a quorum for all purposes;
     provided, however, that if the Company or a class of Shareholders shall
     have only one Shareholder, one Shareholder present in 

19
<PAGE>
 
     person or by proxy shall constitute the necessary quorum.

50.  If within five minutes (or such longer time as the chairman of the meeting
     may determine to wait) after the time appointed for the meeting, a quorum
     is not present, the meeting, if convened on the requisition of
     Shareholders, shall be dissolved.  In any other case, it shall stand
     adjourned to such other day and such other time and place as the chairman
     of the meeting may determine and at such adjourned meeting two Shareholders
     present in person or by proxy shall be a quorum provided that if the
     Company or a class of Shareholders shall have only one Shareholder, one
     Shareholder present in person or by proxy shall constitute the necessary
     quorum.  The Company shall give not less than 5 days notice of any
     meeting adjourned through want of a quorum and such notice shall state that
     the sole Shareholder or, if more than one, two Shareholders present in
     person or by proxy (whatever the number of shares held by them) shall be a
     quorum.

51.  A meeting of the Shareholders or any class thereof may be held by means of
     such telephone, electronic or other communication facilities as permit all
     persons participating in the meeting to communicate with each other
     simultaneously and instantaneously and participation in such a meeting
     shall constitute presence in person at such meeting.

52.  Each Director upon giving the notice referred to in Bye-Law 47 above, and
     the Resident Representative, if any, shall be entitled to attend and speak
     at any general meeting of the Company.

53.  The Chairman (if any) of the Board or, in his absence, the President shall
     preside as chairman at every general meeting.  If there is no such 

20
<PAGE>
 
     Chairman or President, or if at any meeting neither the Chairman nor the
     President is present within five minutes after the time appointed for
     holding the meeting, or if neither of them is willing to act as chairman,
     the Directors present shall choose one of their number to act or if one
     Director only is present he shall preside as chairman if willing to act. If
     no Director is present, or if each of the Directors present declines to
     take the chair, the persons present and entitled to vote on a poll shall
     elect one of their number to be chairman.

54.  The chairman of the meeting may, with the consent of any meeting at which a
     quorum is present (and shall if so directed by the meeting), adjourn the
     meeting from time to time and from place to place but no business shall be
     transacted at any adjourned meeting except business which might lawfully
     have been transacted at the meeting from which the adjournment took place.
     When a meeting is adjourned for three months or more, notice of the
     adjourned meeting shall be given as in the case of an original meeting.

55.  Save as expressly provided by these Bye-Laws, it shall not be necessary to
     give any notice of an adjournment or of the business to be transacted at an
     adjourned meeting.


                                     VOTING
                                        
56.  Save where a greater majority is required by the Companies Acts or these
     Bye-Laws, any question proposed for consideration at any general meeting
     shall be decided on by a simple majority of votes cast.

57.  At any general meeting, a resolution put to the vote of the meeting shall
     be decided on a show of hands unless (before or on the declaration of the

21
<PAGE>
 
     result of the show of hands or on the withdrawal of any other demand for a
     poll) a poll is demanded by:-

     (1)  the chairman of the meeting; or

     (2)  at least three Shareholders present in person or represented by proxy;
          or

     (3)  any Shareholder or Shareholders present in person or represented by
          proxy and holding between them not less than one tenth of the total
          voting rights of all the Shareholders having the right to vote at such
          meeting; or

     (4)  a Shareholder or Shareholders present in person or represented by
          proxy holding shares conferring the right to vote at such meeting,
          being shares on which an aggregate sum has been paid up equal to not
          less than one tenth of the total sum paid up on all such shares
          conferring such right.


     The demand for a poll may be withdrawn by the person or any of the persons
     making it at any time prior to the declaration of the result.  Unless a
     poll is so demanded and the demand is not withdrawn, a declaration by the
     chairman that a resolution has, on a show of hands, been carried or carried
     unanimously or by a particular majority or not carried by a particular
     majority or lost shall be final and conclusive, and an entry to that effect
     in the minute book of the Company shall be conclusive evidence of the fact


     without proof of the number or proportion of votes recorded for or against
     such resolution.

58.  If a poll is duly demanded, the result of the poll shall be deemed to be
     the resolution of the meeting at which the poll is demanded.

22
<PAGE>
 
59.  A poll demanded on the election of a chairman, or on a question of
     adjournment, shall be taken forthwith.  A poll demanded on any other
     question shall be taken in such manner and either forthwith or at such time
     (being not later than three months after the date of the demand) and place
     as the chairman shall direct.  It shall not be necessary (unless the
     chairman otherwise directs) for notice to be given of a poll.

60.  The demand for a poll shall not prevent the continuance of a meeting for
     the transaction of any business other than the question on which the poll
     has been demanded and it may be withdrawn at any time before the close of
     the meeting or the taking of the poll, whichever is the earlier.

61.  On a poll, votes may be cast either personally or by proxy.

62.  A person entitled to more than one vote on a poll need not use all his
     votes or cast all the votes he uses in the same way.

63.  In the case of an equality of votes at a general meeting, whether on a show
     of hands or on a poll, the chairman of such meeting shall not be entitled
     to a second or casting vote and the resolution shall fail.

64.  In the case of joint holders of a share, the vote of the senior who tenders
     a vote, whether in person or by proxy, shall be accepted to the exclusion
     of the votes of the other joint holders, and for this purpose seniority
     shall be determined by the order in which the names stand in the Register
     in respect of the joint holding.

65.  A Shareholder who is a patient for any purpose of any statute or applicable
     law relating to mental health or in respect of whom an order has been made
     by any Court having jurisdiction for the protection or management 

23
<PAGE>
 
     of the affairs of persons incapable of managing their own affairs may vote,
     whether on a show of hands or on a poll, by his receiver, committee,
     curator bonis or other person in the nature of a receiver, committee or
     curator bonis appointed by such Court and such receiver, committee, curator
     bonis or other person may vote on a poll by proxy, and may otherwise act
     and be treated as such Shareholder for the purpose of general meetings.

66.  No Shareholder shall, unless the Board otherwise determines, be entitled to
     vote at any general meeting unless all calls or other sums presently
     payable by him in respect of shares in the Company have been paid.

67.  If;
     (1)  any objection shall be raised to the qualification of any voter; or,

     (2)  any votes have been counted which ought not to have been counted or
          which might have been rejected; or,

     (3)  any votes are not counted which ought to have been counted,
     the objection or error shall not vitiate the decision of the meeting or
     adjourned meeting on any resolution unless the same is raised or pointed
     out at the meeting or, as the case may be, the adjourned meeting at which
     the vote objected to is given or tendered or at which the error occurs.
     Any objection or error shall be referred to the chairman of the meeting and
     shall only vitiate the decision of the meeting on any resolution if the
     chairman decides that the same may have affected the decision of the
     meeting.  The decision of the chairman on such matters shall be final and
     conclusive.


                     PROXIES AND CORPORATE REPRESENTATIVES
                                        

68.  The instrument appointing a proxy shall be in writing under the hand of the
     appointor or of his attorney authorised by him in writing or, if the

24
<PAGE>
 
     appointor is a corporation, either under its seal or under the hand of an
     officer, attorney or other person authorised to sign the same.

69.  Any Shareholder may appoint a standing proxy or (if a corporation)
     representative by depositing at the Registered Office a proxy or (if a
     corporation) an authorisation and such proxy or authorisation shall be
     valid for all general meetings and adjournments thereof or, resolutions in
     writing, as the case may be, until notice of revocation is received at the
     Registered Office.  Where a standing proxy or authorisation exists, its
     operation shall be deemed to have been suspended at any general meeting or
     adjournment thereof at which the Shareholder is present or in respect to
     which the Shareholder has specially appointed a proxy or representative.
     The Board may from time to time require such evidence as it shall deem
     necessary as to the due execution and continuing validity of any such
     standing proxy or authorisation and the operation of any such standing
     proxy or authorisation shall be deemed to be suspended until such time as
     the Board determines that it has received the requested evidence or other
     evidence satisfactory to it.

70.  Subject to Bye-Law 69, the instrument appointing a proxy together with such
     other evidence as to its due execution as the Board may from time to time
     require, shall be delivered at the Registered Office (or at such place as
     may be specified in the notice convening the meeting or in any notice of
     any adjournment or, in either case or the case of a written resolution, in
     any document sent therewith) prior to the holding of the relevant meeting
     or adjourned meeting at which the person named in the instrument proposes
     to vote or, in the case of a poll taken subsequently to the date of a
     meeting 

25
<PAGE>
 
     or adjourned meeting, before the time appointed for the taking of the poll,
     or, in the case of a written resolution, prior to the effective date of the
     written resolution and in default the instrument of proxy shall not be
     treated as valid.

71.  Instruments of proxy shall be in any common form or in such other form as
     the Board may approve and the Board may, if it thinks fit, send out with
     the notice of any meeting or any written resolution forms of instruments of
     proxy for use at that meeting or in connection with that written
     resolution.  The instrument of proxy shall be deemed to confer authority to
     demand or join in demanding a poll and to vote on any amendment of a
     written resolution or amendment of a resolution put to the meeting for
     which it is given as the proxy thinks fit.  The instrument of proxy shall
     unless the contrary is stated therein be valid as well for any adjournment
     of the meeting as for the meeting to which it relates.

72.  A vote given in accordance with the terms of an instrument of proxy shall
     be valid notwithstanding the previous death or unsoundness of mind of the
     principal, or revocation of the instrument of proxy or of the authority
     under which it was executed, provided that no intimation in writing of such
     death, insanity or revocation shall have been received by the Company at
     the Registered Office (or such other place as may be specified for the
     delivery of instruments of proxy in the notice convening the meeting or
     other documents sent therewith) one hour at least before the commencement
     of the meeting or adjourned meeting, or the taking of the poll, or the day
     before the effective date of any written resolution at which the instrument
     of proxy is used.

26
<PAGE>
 
73.  Subject to the Companies Acts, the Board may at its discretion waive any of
     the provisions of these Bye-Laws related to proxies or authorisations and,
     in particular, may accept such verbal or other assurances as it thinks fit
     as to the right of any person to attend and vote on behalf of any
     Shareholder at general meetings or to sign written resolutions.


                      APPOINTMENT AND REMOVAL OF DIRECTORS
                                        


74.  The number of Directors shall be such number not less than two as the
     Company by Resolution may from time to time determine and, subject to the
     Companies Acts and these Bye-Laws, the Directors shall serve until re-
     elected or their successors are appointed at the next Annual General
     Meeting.  All Directors, upon election or appointment, must provide written
     acceptance of their appointment, in such form as the Board may think fit,
     by notice in writing to the Registered Office within thirty days of their
     appointment.

75.  The Company shall at the Annual General Meeting and may by Resolution
     determine the minimum and the maximum number of Directors and may by
     Resolution determine that one or more vacancies in the Board shall be
     deemed casual vacancies for the purposes of these Bye-Laws.  Without
     prejudice to the power of the Company by Resolution in pursuance of any of
     the provisions of these Bye-Laws to appoint any person to be a Director,
     the Board, so long as a quorum of Directors remains in office, shall have
     power at any time and from time to time to appoint any individual to be a
     Director so as to fill a casual vacancy.

27
<PAGE>
 
76.  The Company may in a Special General Meeting called for that purpose remove
     a Director provided notice of any such meeting shall be served upon the
     Director concerned not less than 14 days before the meeting and he shall
be entitled to be heard at that meeting.  Any vacancy created by the removal of
a Director at a Special General Meeting may be filled at the Meeting by the
election of another Director in his place or, in the absence of any such
election, by the Board.


     RESIGNATION AND DISQUALIFICATION OF DIRECTORS
                                        
77.  The office of a Director shall be vacated upon the happening of any of the
     following events:

     (1)  if he resigns his office by notice in writing delivered to the
          Registered Office or tendered at a meeting of the Board;

     (2)  if he becomes of unsound mind or a patient for any purpose of any
          statute   or applicable law relating to mental health and the Board
          resolves that his office is vacated;

     (3)  if he becomes bankrupt under the laws of any country or compounds with
          his creditors;

     (4)  if he is prohibited by law from being a Director;

     (5)  if he ceases to be a Director by virtue of the Companies Acts or is
          removed from office pursuant to these Bye-Laws.


                              ALTERNATE DIRECTORS
                                        
77.  A Director may appoint and remove his own Alternate Director. Any
     appointment or removal of an Alternate Director by a Director shall be
     effected by depositing a notice of appointment or removal with the
     Secretary at the Registered Office, signed by such Director, and such
     appointment or removal shall become effective on the date of receipt by 

28
<PAGE>
 
     the Secretary. Any Alternate Director may be removed by resolution of the
     Board. Subject as aforesaid, the office of Alternate Director shall
     continue until the next annual election of Directors or, if earlier, the
     date on which the relevant


     Director ceases to be a Director.  An Alternate Director may also be a
     Director in his own right and may act as alternate to more than one
     Director.


79.  An Alternate Director shall be entitled to receive notices of all meetings
     of Directors, to attend, be counted in the quorum and vote at any such
     meeting at which any Director to whom he is alternate is not personally
     present, and generally to perform all the functions of any Director to whom
     he is alternate in his absence.


80.  Every person acting as an Alternate Director shall (except as regards
     powers to appoint an alternate and remuneration) be subject in all respects
     to the provisions of these Bye-Laws relating to Directors and shall alone
     be responsible to the Company for his acts and defaults and shall not be
     deemed to be the agent of or for any Director for whom he is alternate.  An
     Alternate Director may be paid expenses and shall be entitled to be
     indemnified by the Company to the same extent mutatis mutandis as if he
     were a Director.  Every person acting as an Alternate Director shall have
     one vote for each Director for whom he acts as alternate (in addition to
     his own vote if he is also a Director).  The signature of an Alternate
     Director to any resolution in writing of the Board or a committee of the
     Board shall, unless the terms of his appointment provides to the contrary,
     be as effective as the signature of the Director or Directors to whom he is
     alternate.

           DIRECTORS' FEES AND ADDITIONAL REMUNERATION AND 

                                   EXPENSES



81.  The amount, if any, of Directors' fees shall from time to time be
     determined by the Company by Resolution and in the absence of a
     determination to the contrary such fees shall be deemed to accrue from day
     to day. Each Director may be paid his reasonable travel, hotel and
     incidental expenses in attending

30
<PAGE>
 
     and returning from meetings of the Board or committees constituted pursuant
     to these Bye-Laws or general meetings and shall be paid all expenses
     properly and reasonably incurred by him in the conduct of the Company's
     business or in the discharge of his duties as a Director.  Any Director
     who, by request, goes or resides abroad for any purposes of the Company or
     who performs services which in the opinion of the Board go beyond the
     ordinary duties of a Director may be paid such extra remuneration (whether
     by way of salary, commission, participation in profits or otherwise) as the
     Board may determine, and such extra remuneration shall be in addition to
     any remuneration provided for by or pursuant to any other Bye-Law.



                             DIRECTORS' INTERESTS
                                        


82.  (1)  A Director may hold any other office or place of profit with the
          Company (except that of auditor) in conjunction with his office of
          Director for such period and upon such terms as the Board may
          determine, and may be paid such extra remuneration therefor (whether
          by way of salary, commission, participation in profits or otherwise)
          as the Board may determine, and such extra remuneration shall be in
          addition to any remuneration provided for by or pursuant to any other
          Bye-Law.

     (2)  A Director may act by himself or his firm in a professional capacity
          for the Company (otherwise than as auditor) and he or his firm shall
          be entitled to remuneration for professional services as if he were
          not a Director.

     (3)  Subject to the provisions of the Companies Acts, a Director may
          notwithstanding his office be a party to, or otherwise interested in,
          any transaction or arrangement with the Company or in which the
          Company is otherwise interested; and be a director or other officer

31
<PAGE>
 
          of, or employed by, or a party to any transaction or arrangement with,
          or otherwise interested in, any body corporate promoted by the Company
          or in which the Company is interested.  The Board may also cause the
          voting power conferred by the shares in any other company held or
          owned by the Company to be exercised in such manner in all respects as
          it thinks fit, including the exercise thereof in favour of any
          resolution appointing the Directors or any of them to be directors or
          officers of such other company, or voting or providing for the payment
          of remuneration to the directors or officers of such other company.

     (4)  So long as, where it is necessary, he declares the nature of his
          interest at the first opportunity at a meeting of the Board or by
          writing to the Directors as required by the Companies Acts, a Director
          shall not by reason of his office be accountable to the Company for
          any benefit which he derives from any office or employment to which
          these Bye-Laws allow   him to be appointed or from any transaction or
          arrangement in which these Bye-Laws allow him to be interested, and no
          such transaction or arrangement shall be liable to be avoided on the
          ground of any interest or benefit.

     (5)  Subject to the Companies Acts and any further disclosure required
          thereby, a general notice to the Directors by a Director or Officer
          declaring that he is a director or officer or has an interest in a
          person and is to be regarded as interested in any transaction or
          arrangement made with that person, shall be a sufficient declaration
          of interest in relation to any transaction or arrangement so made.


                        POWERS AND DUTIES OF THE BOARD
 

32
<PAGE>
 
83.  Subject to the provisions of the Companies Acts and these Bye-Laws and to
     any directions given by the Company by Resolution, the Board shall manage

33
<PAGE>
 
     the business of the Company and may pay all expenses incurred in promoting
     and incorporating the Company and may exercise all the powers of the
     Company.  No alteration of these Bye-Laws and no such direction shall
     invalidate any prior act of the Board which would have been valid if that
     alteration had not been made or that direction had not been given.  The
     powers given by this Bye-Law shall not be limited by any special power
     given to the Board by these Bye-Laws and a meeting of the Board at which a
     quorum is present shall be competent to exercise all the powers,
     authorities and discretions for the time being vested in or exercisable by
     the Board.


84.  The Board may exercise all the powers of the Company to borrow money and to
     mortgage or charge all or any part of the undertaking, property and assets
     (present and future) and uncalled capital of the Company and to issue
     debentures and other securities, whether outright or as collateral security
     for any debt, liability or obligation of the Company or of any other
     persons.


85.  All cheques, promissory notes, drafts, bills of exchange and other
     instruments, whether negotiable or transferable or not, and all receipts
     for money paid to the Company shall be signed, drawn, accepted, endorsed or
     otherwise executed, as the case may be, in such manner as the Board shall
     from time to time by resolution determine.


86.  The Board on behalf of the Company may provide benefits, whether by the
     payment of gratuities or pensions or otherwise, for any person including
     any Director or former Director who has held any executive office or
     employment with the Company or with any body corporate which is or has been
     a subsidiary or affiliate of the Company or a predecessor in the business
     of the Company or of any such subsidiary or affiliate, and to any 

34
<PAGE>
 
     member of his family or any person who is or was dependent on him, and may
     contribute to any fund and pay premiums for the purchase or provision

35
<PAGE>
 
     of any such gratuity, pension or other benefit, or for the insurance of any
     such person.


87.  The Board may from time to time appoint one or more of its body to be a
     managing director, joint managing director or an assistant managing
     director or to hold any other employment or executive office with the
     Company for such period and upon such terms as the Board may determine and
     may revoke or terminate any such appointments.  Any such revocation or
     termination as aforesaid shall be without prejudice to any claim for
     damages that such Director may have against the Company or the Company may
     have against such Director for any breach of any contract of service
     between him and the Company which may be involved in such revocation or
     termination. Any person so appointed shall receive such remuneration (if
     any) (whether by way of salary, commission, participation in profits or
     otherwise) as the Board may determine, and either in addition to or in lieu
     of his remuneration as a Director.


                       DELEGATION OF THE BOARD'S POWERS
                                        


88.  The Board may by power of attorney appoint any company, firm or person or
     any fluctuating body of persons, whether nominated directly or indirectly
     by the Board, to be the attorney or attorneys of the Company for such
     purposes and with such powers, authorities and discretions (not exceeding
     those vested in or exercisable by the Board under these Bye-Laws) and for
     such period and subject to such conditions as it may think fit, and any
     such power of attorney may contain such provisions for the protection and
     convenience of persons dealing with any such attorney and of such attorney
     as the Board may think fit, and may also authorise any such attorney to
     sub-delegate all or any of the powers, authorities and discretions vested
     in him.

36
<PAGE>
 
89.  The Board may entrust to and confer upon any Director, Officer or, without
     prejudice to the provisions of Bye-Law 90, other individual any of the
     powers exercisable by it upon such terms and conditions with such
     restrictions as it thinks fit, and either collaterally with, or to the
     exclusion of, its own powers, and may from time to time revoke or vary all
     or any of such powers but no person dealing in good faith and without
     notice of such revocation or variation shall be affected thereby.


90.  The Board may delegate any of its powers, authorities and discretions to
     committees, consisting of such person or persons (whether a member or
     members of its body or not) as it thinks fit.  Any committee so formed
     shall, in the exercise of the powers, authorities and discretions so
     delegated, and in conducting its proceedings conform to any regulations
     which may be imposed upon it by the Board.  If no regulations are imposed
     by the Board the proceedings of a committee with two or more members shall
     be, as far as is practicable, governed by the Bye-Laws regulating the
     proceedings of the Board.


                           PROCEEDINGS OF THE BOARD
                                        


91.  The Board may meet for the despatch of business, adjourn and otherwise
     regulate its meetings as it thinks fit. Questions arising at any meeting
     shall be determined by a majority of votes.  In the case of an equality of
     votes the motion shall be deemed to have been lost.  A Director may, and
     the Secretary on the requisition of a Director shall, at any time summon a
     meeting of the Board.


92.  Notice of a meeting of the Board shall be deemed to be duly given to a
     Director if it is given to him personally or by word of mouth or sent to
     him 

37
<PAGE>
 
by post, cable, telex, telecopier or other mode of representing or
reproducing

38
<PAGE>
 
     words in a legible and non-transitory form at his last known address or any
     other address given by him to the Company for this purpose.  A Director may
     retrospectively waive the requirement for notice of any meeting by
     consenting in writing to the business conducted at the meeting.



93.  (1)  The quorum necessary for the transaction of the business of the Board
          may be fixed by the Board and, unless so fixed at any other number,
          shall be two individuals.  Any Director who ceases to be a Director at
          a meeting of the Board may continue to be present and to act as a
          Director and be counted in the quorum until the termination of the
          meeting if no other Director objects and if otherwise a quorum of
          Directors would not be present.

     (2)  A Director who to his knowledge is in any way, whether directly or
          indirectly, interested in a contract or proposed contract, transaction
          or arrangement with the Company and has complied with the provisions
          of the Companies Acts and these Bye-Laws with regard to disclosure of
          his interest shall be entitled to vote in respect of any contract,
          transaction or arrangement in which he is so interested and if he
          shall do so his vote shall be counted, and he shall be taken into
          account in ascertaining whether a quorum is present.

     (3)  The Resident Representative shall, upon delivering written notice of
          an address for the purposes of receipt of notice, to the Registered
          Office, be entitled to receive notice of, attend and be heard at, and
          to receive minutes of all meetings of the Board.


94.  So long as a quorum of Directors remains in office, the continuing
     Directors may act notwithstanding any vacancy in the Board but, if no such
     quorum remains, the continuing 

39
<PAGE>
 
Directors or a sole continuing Director may act only for the purpose of calling
a general meeting.

40
<PAGE>
 
95.  The Chairman (or President) or, in his absence, the Deputy Chairman (or
     Vice-President), shall preside as chairman at every meeting of the Board.
     If at any meeting the Chairman or Deputy Chairman (or the President or
     Vice-President) is not present within five minutes after the time appointed
     for holding the meeting, or is not willing to act as chairman, the
     Directors present may choose one of their number to be chairman of the
     meeting.


96.  The meetings and proceedings of any committee consisting of two or more
     members shall be governed by the provisions contained in these Bye-Laws for
     regulating the meetings and proceedings of the Board so far as the same are
     applicable and are not superseded by any regulations imposed by the Board.


97.  A resolution in writing signed by all the Directors for the time being
     entitled to receive notice of a meeting of the Board or by all the members
     of a committee for the time being shall be as valid and effectual as a
     resolution passed at a meeting of the Board or, as the case may be, of such
     committee duly called and constituted.  Such resolution may be contained in
     one document or in several documents in the like form each signed by one or
     more of the Directors or members of the committee concerned.


98.  A meeting of the Board or a committee appointed by the Board may be held by
     means of such telephone, electronic or other communication facilities as
     permit all persons participating in the meeting to communicate with each
     other simultaneously and instantaneously and participation in such a
     meeting shall constitute presence in person at such meeting.


99.  All acts done by the Board or by any committee or by any person acting as 

41
<PAGE>
 
     a Director or member of a committee or any person duly authorised by the
     Board or any committee, shall, notwithstanding that it is afterwards

42
<PAGE>
 
     discovered that there was some defect in the appointment of any member of
     the Board or such committee or person acting as aforesaid or that they or
     any of them were disqualified or had vacated their office, be as valid as
     if every such person had been duly appointed and was qualified and had
     continued to be a Director, member of such committee or person so
     authorised.



                                   OFFICERS
                                        


100. The Officers of the Company shall include a President and a Vice-President
     or a Chairman and a Deputy Chairman who shall be Directors and shall be
     elected by the Board as soon as possible after the statutory meeting and
     each Annual General Meeting.  In addition, the Board may appoint any person
     whether or not he is a Director to hold such office as the Board may from
     time to time determine.  Any person elected or appointed pursuant to this
     Bye-Law shall hold office for such period and upon such terms as the Board
     may determine and the Board may revoke or terminate any such election or
     appointment.  Any such revocation or termination shall be without prejudice
     to any claim for damages that such Officer may have against the Company or
     the Company may have against such Officer for any breach of any contract of
     service between him and the Company which may be involved in such
     revocation or termination.  Save as provided in the Companies Acts or these
     Bye-Laws, the powers and duties of the Officers of the Company shall be
     such (if any) as are determined from time to time by the Board.


                                    MINUTES
                                        


101. The Board shall cause minutes to be made and books kept for the purpose 

43
<PAGE>
 
     of recording -

     (1) all appointments of Officers made by the Board;

44
<PAGE>
 
     (2)  the names of the Directors and other persons (if any) present at each
          meeting of the Board and of any committee;

     (3)  of all proceedings at meetings of the Company, of the holders of any
          class of shares in the Company, of the Board and of committees
          appointed by the Board or the Shareholders;

     (4) of all proceedings of its managers (if any).

     Shareholders shall only be entitled to see the Register of Directors and
     Officers, the Register, the financial information provided for in Bye-Law
     118 and the minutes of meetings of the Shareholders of the Company.



                     SECRETARY AND RESIDENT REPRESENTATIVE
                                        

102. The Secretary (including one or more deputy or assistant secretaries) and,
     if required, the Resident Representative, shall be appointed by the Board
     at such remuneration (if any) and upon such terms as it may think fit and
     any Secretary and Resident Representative so appointed may be removed by
     the Board.  The duties of the Secretary and the duties of the Resident
     Representative shall be those prescribed by the Companies Acts together
     with such other duties as shall from time to time be prescribed by the
     Board.


103. A provision of the Companies Acts or these Bye-Laws requiring or
     authorising a thing to be done by or to a Director and the Secretary shall
     not be satisfied by its being done by or to the same person acting both as
     Director and as, or in the place of, the Secretary.


                                   THE SEAL


104. (1)  The Seal shall consist of a circular metal device with the name of 

45
<PAGE>
 
          the Company around the outer margin thereof and the country and year
          of incorporation across the centre thereof. Should the Seal not have

46
<PAGE>
 
          been received at the Registered Office in such form at the date of
          adoption of this Bye-Law then, pending such receipt, any document
          requiring to be sealed with the Seal shall be sealed by affixing a red
          wafer seal to the document with the name of the Company, and the
          country and year of incorporation type written across the centre
          thereof.

     (2)  The Board shall provide for the custody of every Seal.  A Seal shall
          only be used by authority of the Board or of a committee constituted
          by the Board.  Subject to these Bye-laws, any instrument to which a
          Seal is affixed shall be signed by either two Directors, or by the
          Secretary and one Director, or by the Secretary or by any one person
          whether or not a Director or Officer, who has been authorised either
          generally or specifically to affirm the use of a Seal; provided that
          the Secretary or a Director may affix a Seal over his signature alone
          to authenticate copies of these Bye-Laws, the minutes of any meeting
          or any other documents requiring authentication


                         DIVIDENDS AND OTHER PAYMENTS
                                        


105. The Board may from time to time declare dividends or distributions out of
     contributed surplus to be paid to the Shareholders according to their
     rights and interests including such interim dividends as appear to the
     Board to be justified by the position of the Company.  The Board, in its
     discretion, may determine that any dividend shall be paid in cash or shall
     be satisfied, subject to Bye-Law 113, in paying up in full shares in the
     Company to be issued to the Shareholders credited as fully paid or partly
     paid or partly in one way and partly the other.  The Board may also pay any
     fixed cash dividend which is payable on any shares of the Company half
     yearly or on such other dates, whenever the position of the Company, in the
     opinion of 

47
<PAGE>
 
     the Board, justifies such payment.


106. Except insofar as the rights attaching to, or the terms of issue of, any
     share otherwise provide:-

     (1)  all dividends or distributions out of contributed surplus may be
          declared and paid according to the amounts paid up on the shares in
          respect of which the dividend or distribution is paid, and an amount
          paid up on a share in advance of calls may be treated for the purpose
          of this Bye-Law as paid-up on the share;
     
     (2)  dividends or distributions out of contributed surplus may be
          apportioned and paid pro rata according to the amounts paid-up on the
          shares during any portion or portions of the period in respect of
          which the dividend or distribution is paid.


107. The Board may deduct from any dividend, distribution or other moneys
     payable to a Shareholder by the Company on or in respect of any shares all
     sums of money (if any) presently payable by him to the Company on account
     of calls or otherwise in respect of shares of the Company.

108. No dividend, distribution or other moneys payable by the Company on or in
     respect of any share shall bear interest against the Company.


109. Any dividend, distribution or interest, or part thereof payable in cash,
     or any other sum payable in cash to the holder of shares may be paid by
     cheque or warrant sent through the post addressed to the holder at his
     address in the Register or, in the case of joint holders, addressed to the
     holder whose name stands first in the Register in respect of the shares at
     his registered address as appearing in the Register or addressed to such
     person at such address as the holder or joint holders may in writing
     direct.  Every such cheque or warrant shall, unless the holder or joint
     holders 

48
<PAGE>
 
     otherwise direct, be made payable to the order of the holder or, in
     the case of joint holders, to the order of the

49
<PAGE>
 
     holder whose name stands first in the Register in respect of such shares,
     and shall be sent at his or their risk and payment of the cheque or warrant
     by the bank on which it is drawn shall constitute a good discharge to the
     Company. Any one of two or more joint holders may give effectual receipts
     for any dividends, distributions or other moneys payable or property
     distributable in respect of the shares held by such joint holders.


110. Any dividend or distribution out of contributed surplus unclaimed for a
     period of six years from the date of declaration of such dividend or
     distribution shall be forfeited and shall revert to the Company and the
     payment by the Board of any unclaimed dividend, distribution, interest or
     other sum payable on or in respect of the share into a separate account
     shall not constitute the Company a trustee in respect thereof.


111. The Board may also, in addition to its other powers, direct payment or
     satisfaction of any dividend or distribution out of contributed surplus
     wholly or in part by the distribution of specific assets, and in particular
     of paid-up shares or debentures of any other company, and where any
     difficulty arises in regard to such distribution or dividend the Board may
     settle it as it thinks expedient, and in particular, may authorise any
     person to sell and transfer any fractions or may ignore fractions
     altogether, and may fix the value for distribution or dividend purposes of
     any such specific assets and may determine that cash payments shall be made
     to any Shareholders upon the footing of the values so fixed in order to
     secure equality of distribution and may vest any such specific assets in
     trustees as may seem expedient to the Board provided that such dividend or
     distribution may not be satisfied by the distribution of any partly paid
     shares or debentures of any company without the sanction of a Resolution.

                                   RESERVES
                                        


112. The Board may, before recommending or declaring any dividend or
     distribution out of contributed surplus, set aside such sums as it thinks
     proper as reserves which shall, at the discretion of the Board, be
     applicable for any purpose of the Company and pending such application may,
     also at such discretion, either be employed in the business of the Company
     or be invested in such investments as the Board may from time to time think
     fit.  The Board may also without placing the same to reserve carry forward
     any sums which it may think it prudent not to distribute.



                           CAPITALIZATION OF PROFITS

                                        

113. The Board may, from time to time resolve to capitalise all or any part of
     any amount for the time being standing to the credit of any reserve or fund
     which is available for distribution or to the credit of any share premium
     account and accordingly that such amount be set free for distribution
     amongst the Shareholders or any class of Shareholders who would be entitled
     thereto if distributed by way of dividend and in the same proportions, on
     the footing that the same be not paid in cash but be applied either in or
     towards paying up amounts for the time being unpaid on any shares in the
     Company held by such Shareholders respectively or in payment up in full of
     unissued shares, debentures or other obligations of the Company, to be
     allotted and distributed credited as fully paid amongst such Shareholders,
     or partly in one way and partly in the other, provided that for the purpose
     of this Bye-Law, a share premium account may be applied only in paying up
     of unissued shares to be issued to such Shareholders credited as fully paid
     and provided further that any sum standing to the credit of a share premium
     account may only be applied in crediting as fully paid shares of the same
     class as that from which the 

51
<PAGE>
 
     relevant share premium was derived.


114. Where any difficulty arises in regard to any distribution under the last
     preceding Bye-Law, the Board may settle the same as it thinks expedient
     and, in particular, may authorise any person to sell and transfer any
     fractions or may resolve that the distribution should be as nearly as may
     be practicable in the correct proportion but not exactly so or may ignore
     fractions altogether, and may determine that cash payments should be made
     to any Shareholders in order to adjust the rights of all parties, as may
     seem expedient to the Board.  The Board may appoint any person to sign on
     behalf of the persons entitled to participate in the distribution any
     contract necessary or desirable for giving effect thereto and such
     appointment shall be effective and binding upon the Shareholders.

115. Notwithstanding any other provisions of these Bye-Laws, the Company may by
     Resolution or the Board may fix any date as the record date for any
     dividend, distribution, allotment or issue and for the purpose of
     identifying the persons entitled to receive notices of general meetings.

117. The records of account shall be kept at the Registered Office or at such
     other place or places as the Board thinks fit, and shall at all times be
     open to inspection by the Directors: PROVIDED that if the records of
     account are kept at some place outside Bermuda, there shall be kept at an
     office of the Company in Bermuda such records as will enable the Directors
     to ascertain with reasonable accuracy the financial position of the Company
     at the end of each three month period.  No Shareholder (other than an
     Officer of the Company) shall have any right to inspect any accounting
     record or book or document of the Company except as conferred by law or
     authorised by the Board or by Resolution.


118. A copy of every balance sheet and statement of income and expenditure,

                                     AUDIT
                                        


119. Save and to the extent that an audit is waived in the manner permitted by
     the Companies Acts, auditors shall be appointed and their duties regulated
     in accordance with the Companies Acts, any other applicable law and such
     requirements not inconsistent with the Companies Acts as the Board may from
     time to time determine.


                    SERVICE OF NOTICES AND OTHER DOCUMENTS
                                        


120. Any notice or other document (including a share certificate) may be served
     on or delivered to any Shareholder by the Company either personally or by

53
<PAGE>
 
     sending it through the post (by airmail where applicable) in a pre-paid
     letter addressed to such Shareholder at his address as appearing in the
     Register or by delivering it to or leaving it at such registered address.
     In the case of joint holders of a share, service or delivery of any notice
     or other document on or to one of the joint holders shall for all purposes
     be deemed as sufficient service on or delivery to all the joint holders.
     Any notice or other document if sent by post shall be deemed to have been
     served or delivered seven days after it was put in the post, and in proving
     such service or delivery, it shall be sufficient to prove that the notice
     or document was properly addressed, stamped and put in the post.


121. Any notice of a general meeting of the Company shall be deemed to be duly
     given to a Shareholder, or other person entitled to it, if it is sent to

     reproducing words in a legible and non-transitory form at his address as
     appearing in the Register or any other address given by him to the Company
     for this purpose.  Any such notice shall be deemed to have been served
     twenty-four hours after its despatch.


122. Any notice or other document delivered, sent or given to a Shareholder in
     any manner permitted by these Bye-Laws shall, notwithstanding that such
     Shareholder is then dead or bankrupt or that any other event has occurred,
     and whether or not the Company has notice of the death or bankruptcy or
     other event, be deemed to have been duly served or delivered in respect of
     any share registered in the name of such Shareholder as sole or joint
     holder unless his name shall, at the time of the service or delivery of the
     notice or document, have been removed from the Register as the holder of
     the share, and such service or delivery shall for all purposes be deemed as
     sufficient 

54
<PAGE>
 
     service or delivery of such notice or document on all persons interested
     (whether jointly with or as claiming through or under him) in the share.



                                  WINDING UP
                                        


123. If the Company shall be wound up, the liquidator may, with the sanction of
     a Resolution of the Company and any other sanction required by the
     Companies Acts, divide amongst the Shareholders in specie or kind the whole
     or any part of the assets of the Company (whether they shall consist of
     property of the same kind or not) and may for such purposes set such values
     as he deems fair upon any property to be divided as aforesaid and may
     determine how such division shall be carried out as between the
     Shareholders or different classes of Shareholders.  The liquidator may,
     with the like sanction, vest the whole or any part of such assets in
     trustees upon such trust for the benefit of the contributories as the
     liquidator, with the like sanction, shall think fit, but so that no
     Shareholder shall be compelled to accept any shares or other assets upon
     which there is any liability.


                                   INDEMNITY
                                        


124. Subject to the proviso below, every Director, Officer of the Company and
     member of a committee constituted under Bye-Law 90 and any Resident
     Representative shall be indemnified out of the funds of the Company against
     all liabilities, loss, damage or expense (including but not limited to
     liabilities under contract, tort and statute or any applicable foreign law
     or regulation and all reasonable legal and other costs and expenses
     properly payable) incurred or suffered by him as such Director, Officer,
     committee 

55
<PAGE>
 
     member or Resident Representative and the indemnity contained in this Bye-
     Law shall extend to any person acting as a Director, Officer, committee
     member or Resident Representative in the reasonable belief that he has been
     so appointed or elected notwithstanding any defect in such appointment or
     election PROVIDED ALWAYS that the indemnity contained in this Bye-

56
<PAGE>
 
     Law shall not extend to any matter which would render it void pursuant to
     the Companies Acts.


125. Every Director, Officer, member of a committee duly constituted under Bye-
     Law 90 or Resident Representative of the Company shall be indemnified out
     of the funds of the Company against all liabilities incurred by him as such
     Director, Officer, committee member or Resident Representative in defending
     any proceedings, whether civil or criminal, in which judgement is given in
     his favour, or in which he is acquitted, or in connection with any
     application under the Companies Acts in which relief from liability is
     granted to him by the court.
 

126. To the extent that any Director, Officer, member of a committee duly
     constituted under Bye-Law 90 or Resident Representative is entitled to
     claim an indemnity pursuant to these Bye-Laws in respect of amounts paid or
     discharged by him, the relative indemnity shall take effect as an
     obligation of the Company to reimburse the person making such payment or
     effecting such discharge.


127. Each Shareholder and the Company agree to waive any claim or right of
     action he or it may at any time have, whether individually or by or in the
     right of the Company, against any Director, Officer, or member of a
     committee duly constituted under Bye-Law 90 on account of any action taken
     by such Director, Officer, or member of a committee or the failure of such
     Director, Officer, or member of a committee to take any action in the
     performance of his duties with or for the Company PROVIDED HOWEVER that
     such waiver shall not apply to any claims or rights of action arising out
     of the fraud of such Director, Officer, or member of a committee duly
     constituted under Bye-Law 90 or to recover any gain,

57
<PAGE>
 
     personal profit or advantage to which such Director, Officer, or member of
     a committee duly constituted under Bye-Law 90 is not legally entitled.



128. Subject to the Companies Acts, expenses incurred in defending any civil or
     criminal action or proceeding for which indemnification is required
     pursuant to Bye-Laws 124 and 125 shall be paid by the Company in advance of
     the final disposition of such action or proceeding upon receipt of an
     undertaking by or on behalf of the indemnified party to repay such amount
     if it shall ultimately be determined that the indemnified party is not
     entitled to be indemnified pursuant to Bye-Laws 124 and 125.



     Each Shareholder of the Company, by virtue of its acquisition and continued
     holding of a share, shall be deemed to have acknowledged and agreed that
     the advances of funds may be made by the Company as aforesaid, and when
     made by the Company under this Bye-Law 128 are made to meet expenditures
     incurred for the purpose of enabling such Director, Officer, or member of a
     committee duly constituted under Bye-Law 90 to properly perform his or her
     duties as an officer of the Company.


                                 AMALGAMATION
                                        


129. Any resolution proposed for consideration at any general meeting to approve
     the amalgamation of the Company with any other company, wherever
     incorporated, shall require the approval of a simple majority of votes cast
     at such meeting and the quorum for such meeting shall be that required in
     Bye-Law 49 and a poll may be demanded in respect of such resolution in
     accordance with the provisions of Bye-Law 57.

                                              Holdings Ltd. Preferred Stock


                                   SCHEDULE A
                                   ----------

                      SENIOR EXCHANGEABLE PREFERRED STOCK

        The terms of the Company's authorized Senior Exchangeable Preferred
Stock shall be as set forth below in this Schedule A.

        (a)     DESIGNATION. There is hereby authorized 7,500,000 shares of
                -----------   
preferred stock as designated by the Company's Board of Directors, of which
5,000,000 shares initially will be authorized, issued and outstanding pursuant
to the Offering, and up to 2,500,000 shares will be designated and reserved for
issuance to pay dividends on the Preferred Stock if the Company elects to pay
dividends on the Preferred Stock in additional shares of Preferred Stock prior
to June 1, 2002 in accordance with the terms of the Preferred Stock. All of such
shares will be designated as shares of Preferred Stock and will have a
liquidation preference of $100.00 per share.

        (b)     CURRENCY. The Preferred Stock shall be denominated in United
                -------- 
States currency and all payments and distributions thereon or with respect
thereto shall be made in United States currency. All references to "$" or
"dollars" refer to United States currency.

        (c)     RANKING.
                ------- 

                (1) The Preferred Stock will rank junior in right of payment to
all indebtedness and other liabilities of the Company. The Company will have the
ability to issue additional shares of Preferred Stock to pay dividends thereon,
if it so elects, on any Dividend Payment Date prior to June 1, 2002.

                (2) With respect to dividends and rights upon the liquidation,
winding-up and dissolution of the Company, the Preferred Stock will rank (i)
senior to each class of capital stock of the Company outstanding or established
after the Issue Date by the Company's Board of Directors the terms of which do
not expressly provide that it ranks senior to, or on a parity with, the
Preferred Stock as to dividends and rights upon the liquidation, winding-up and
dissolution of the Company (collectively referred to herein, together with the
common stock of the Company, as "Junior Securities"); (ii) subject to certain
conditions, on a parity with each other class of preferred stock established
after the Issue Date by the Company's Board of Directors the terms of which
expressly provide that such class or series will rank on a parity with the
Preferred Stock as to dividends and rights upon the liquidation, winding-up and
dissolution of the Company (collectively referred to herein as the "Parity
Securities"); and (iii) subject to certain conditions, junior to each class of
preferred stock established after the Issue Date by the Company's Board of
Directors the terms of which expressly provide that such class or series will
rank senior to the 

                                      61
<PAGE>
 
Preferred Stock as to dividends and rights upon the liquidation, winding-up and
dissolution of the Company (collectively referred to herein as the "Senior
Securities"). The Company may not authorize any new class of Senior Securities
without the approval of the Holders of at least a majority of the then
outstanding shares of Preferred Stock, voting or consenting as a separate class.
The Company may, however, authorize any new class of Parity Securities or Junior
Securities without the approval of any Holder of Preferred Stock.

        (d)     DIVIDENDS.
                --------- 

                (1) The Holders of the Preferred Stock will be entitled to
receive when, as and if dividends are declared by the Company's Board of
Directors out of funds legally available therefor, dividends on the Preferred
Stock from the Issue Date at the rate per annum equal to 10.5% of the
Liquidation Preference per share of Preferred Stock, payable semi-annually in
arrears on each June 1 and December 1, or, if any such date is not a Business
Day, on the next succeeding Business Day (each, a "Dividend Payment Date"), to
the Holders of record as of the immediately preceding May 15 and November 15
(each, a "Record Date"). Dividends will be payable in cash, except that on each
Dividend Payment Date occurring prior to June 1, 2002, dividends may be paid, at
the Company's option, by the issuance of additional shares of Preferred Stock
(including fractional shares) having an aggregate Liquidation Preference per
share of Preferred Stock equal to the amount of such dividends. The issuance of
such additional shares of Preferred Stock will constitute "payment" of the
related dividend for all purposes. The first dividend payment of Preferred Stock
will be payable on June 1, 1999. Beginning on June 1, 2002 dividends on the
Preferred Stock will be payable only in cash. Dividends payable on the Preferred
Stock will be computed on the basis of a 360-day year consisting of twelve 30-
day months.

                (2) Dividends on the Preferred Stock will accrue whether or not
the Company has earnings or profits, whether or not there are funds legally
available for the payment of such dividends and whether or not dividends are
declared. Dividends will accumulate to the extent they are not paid on the
Dividend Payment Date for the period to which they relate. In the event that
dividends on the Preferred Stock are in arrears and unpaid for three or more
semi-annual Dividend Periods (whether or not consecutive), Holders of the
Preferred Stock will be entitled to certain voting rights. See paragraph (g).
The Company will take all actions required or permitted under Bermuda law to
permit the payment of dividends on the Preferred Stock, including, without
limitation, through the revaluation of its assets in accordance with Bermuda
law, and to make or keep funds legally available for the payment of dividends.
Dividends on account of arrears for any past Dividend Period and dividends in
connection with any optional redemption may be declared and paid at any time,
without reference to any regular Dividend Payment Date, to Holders of record of
Preferred Stock on such date, not more than 45 days prior to the payment
thereof, as may be fixed by the Company's Board of Directors.

                (3) No dividend whatsoever shall be declared or paid upon, or
any sum set apart for the payment of dividends upon, any outstanding share of
Preferred Stock with respect to any Dividend Period unless all dividends for all
preceding Dividend Periods have been declared and paid, or declared and a
sufficient sum set apart for the payment of such dividend, upon all 

                                      62
<PAGE>
 
outstanding shares of Preferred Stock. No full dividends may be declared or paid
or funds set apart for the payment of dividends on any Parity Securities for any
period unless full cumulative dividends shall have been or contemporaneously are
declared and paid (or are deemed declared and paid) in full or declared and, if
payable in cash, a sum in cash sufficient for such payment set apart for such
payment on the Preferred Stock. If full dividends are not so paid, the Preferred
Stock will share dividends pro rata with the Parity Securities. So long as any
Preferred Stock is outstanding and unless and until full cumulative dividends
have been paid (or are deemed paid) in full on the Preferred Stock: (i) no
dividend shall be declared or paid upon, or any sum set apart for the payment of
dividends upon, any shares of Junior Securities; (ii) no other distribution
shall be declared or made upon, or any sum set apart for the payment of any
distribution upon, any shares of Junior Securities; (iii) no shares of Parity
Securities or Junior Securities shall be purchased, redeemed or otherwise
acquired or retired for value; (iv) no warrants, rights, calls or options to
purchase any Parity Securities or Junior Securities shall be directly or
indirectly issued; and (v) no monies shall be paid into or set apart or made
available for a sinking or other like fund for the purchase, redemption or other
acquisition or retirement for value of any shares of Parity Securities or Junior
Securities.


        (e)     LIQUIDATION PREFERENCE.
                ---------------------- 

                (1) Upon any voluntary or involuntary liquidation, dissolution
or winding-up of the Company or a reduction or decrease in its capital stock
resulting in a distribution of assets to the holders of any class or series of
the Company's capital stock, each Holder of the Preferred Stock will be entitled
to payment out of the assets of the Company available for distribution of an
amount equal to the then effective Liquidation Preference per share of Preferred
Stock held by such holder, plus all accumulated and unpaid dividends thereon to
the date such liquidation, dissolution, winding-up or reduction or decrease in
capital stock, before any distribution is made on any Junior Securities,
including, without limitation, common stock of the Company. After payment in
full of the then effective Liquidation Preference and all accumulated and unpaid
dividends to which Holders of Preferred Stock are entitled, such Holders will
not be entitled to any further participation in any distribution of assets of
the Company. If, upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Company or a reduction or decrease in its capital stock, the
amounts payable with respect to the Preferred Stock and all other Parity
Securities are not paid in full, the Holders of the Preferred Stock and the
Parity Securities will share equally and ratably in any distribution of assets
of the Company in proportion to the full liquidation preference and all
accumulated and unpaid dividends to which each such Holder is entitled. However,
neither the voluntary sale, conveyance, exchange or transfer (for cash, shares
of stock, securities or other consideration) of all or substantially all of the
property or assets of the Company nor the consolidation or merger of the Company
with or into one or more corporations will be deemed to be a voluntary or
involuntary liquidation, dissolution or winding-up of the Company or reduction
or decrease in capital stock.

                (2) No funds are required to be set aside to protect the
Liquidation Preference of the Preferred Stock, although such Liquidation
Preference will be substantially in excess of the par value of the shares of the
Preferred Stock and there can be no assurance that, upon any such 

                                      63
<PAGE>
 
voluntary or involuntary liquidation, dissolution or winding-up of the Company,
or a reduction or decrease in its capital stock, that there will be funds
available in an amount sufficient to pay such Liquidation Preference in full, in
part or at all.

        (f)     REDEMPTION.
                ---------- 

        (1)     Optional Redemption.
                ------------------- 

                        (i)  Except as set forth below and under paragraph
(f)(3), the Preferred Stock will not be redeemable at the Company's option prior
to December 1, 2003. Thereafter, the Preferred Stock will be subject to
redemption at any time at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, in accordance with the terms of
a redemption notice mailed by the Company, or at the direction of the Company,
by first class mail to each Holder whose Preferred Stock is to be redeemed at
its registered address, at the redemption prices (expressed as percentages of
the then effective Liquidation Preference) set forth below, plus all accumulated
and unpaid dividends thereon to the applicable redemption date, if redeemed
during the twelve-month period beginning on December 1 of the years indicated
below:

                Year                           Percentage
                ----                           ----------
                2003..........................  105.250%
                2004..........................  103.500%
                2005..........................  101.750%
                2006 and thereafter...........  100.000%

                (ii) Notwithstanding the foregoing, at any time prior to
December 1, 2001, the Company may, on any one or more occasions, redeem up to
35% of the then effective aggregate Liquidation Preference of the Preferred
Stock then outstanding at a redemption price equal to 110.500% of the then
effective Liquidation Preference thereof, plus all accumulated and unpaid
dividends thereon to the redemption date, with the net cash proceeds received
from one or more Equity Offerings made by the Company or GCL (to the extent such
net cash proceeds received by GCL were contributed to the Company as common
equity capital); provided that at least 65% of the then effective aggregate
Liquidation Preference of Preferred Stock then outstanding remains outstanding
immediately after the occurrence of any such redemption. The Company may make
any such redemption upon not less than 30 nor more than 60 days' notice (but in
no event more than 90 days after the closing of the related Equity Offering).
Any such notice may be given prior to the completion of the related Equity
Offering and any such redemption may, at the Company's discretion, be subject to
the satisfaction of one or more conditions precedent, including, but not limited
to, the completion of the related Equity Offering.

                (iii) In addition, at any time prior to December 1, 2003, the
Preferred Stock may also be redeemed at the option of the Company, in whole but
not in part, upon the occurrence of a Change of Control, upon not less than 30
nor more than 60 days' prior notice (but in no event may any such redemption
occur more than 90 days after the occurrence of such Change of Control) mailed
by first-class mail to each Holder's registered address, at a redemption 

                                      64

price equal to 100% of the then effective Liquidation Preference thereof, plus
the Applicable Premium as of, and all accumulated and unpaid dividends thereon
to, the date of redemption (the "Redemption Date").

                        (iv) "Applicable Premium" means, with respect to any
share of Preferred Stock on any Redemption Date (a) the present value of (i)
dividends on the Preferred Stock accumulating until and including December 1,
2003 (assuming payment thereof in cash on the applicable Dividend Payment Dates)
and (ii) the Liquidation Preference and any applicable optional redemption
premium therefor payable on such date for such share (assuming payment thereof
on December 1, 2003), computed using a discount rate equal to the Treasury Rate
plus 50 basis points less (b) the Liquidation Preference of $100.00 per share..

                        (v) "Treasury Rate" means, as of any Redemption Date,
the yield to maturity as of such Redemption Date of United States Treasury
securities with a constant maturity (as compiled and published in the most
recent Federal Reserve Statistical Release H.15 (519) that has become publicly
available at least two Business Days prior to the Redemption Date (or, if such
Statistical Release is no longer published, any publicly available source of
similar market data)) most nearly equal to the period from the Redemption Date
to December 1, 2003; provided, however, that if the period from the Redemption
Date to December 1, 2003 is less than one year, the weekly average yield on
actually traded United States Treasury securities adjusted to a constant
maturity of one year shall be used.


                (2)     Mandatory Redemption. On the Mandatory Redemption Date,
                        --------------------  
the Company will be required to redeem all outstanding shares of Preferred Stock
at a price in cash equal to the then effective Liquidation Preference thereof,
plus all accumulated and unpaid dividends thereon to the date of redemption. The
Company will not be required to make sinking fund payments with respect to the
Preferred Stock. The Company will take all actions required or permitted under
Bermuda law to permit such redemption.

                (3)     Optional Tax Redemption
                        -----------------------

                        (i) The Preferred Stock will be subject to redemption at
the option of the Company or a successor corporation at any time, in whole but
not in part, upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to the then effective Liquidation Preference thereof,
plus all accumulated and unpaid dividends thereon to the redemption date if, as
a result of any change in or amendment to the laws or any regulations or ruling
promulgated thereunder of (x) Bermuda or any political subdivision or
governmental authority thereof or therein having the power to tax, (y) any
jurisdiction, other than the United States, from or through which payment on the
Preferred Stock is made by the Company or a successor corporation, or its paying
agent in its capacity as such or any political subdivision or governmental
authority thereof or therein having the power to tax or (z) any other
jurisdiction, other than the United States, in which the Company or a successor
corporation is organized, or any political subdivision or governmental authority
thereof or therein having the power to tax, or any change in the official
application or interpretation of such laws, regulations or rulings, or any

                                      65
<PAGE>
 
change in the official application or interpretation of, or any execution of or
amendment to, any treaty or treaties affecting taxation to which such
jurisdiction (or such political subdivision or taxing authority) is a party (a
"Change in Tax Law"), which becomes effective on or after the date hereof, the
Company or a successor corporation is or would be required on the next
succeeding dividend payment date to pay Additional Amounts with respect to the
Preferred Stock, as described paragraph (f)(4), and the payment of such
Additional Amounts cannot be avoided by the use of any reasonable measures
available to the Company or a successor corporation.

                  (ii) In addition, the Preferred Stock will be subject to
redemption at the option of the Company at any time, in whole but not in part,
upon not less than 30 nor more than 60 days' notice, at a redemption price equal
to the then effective Liquidation Preference thereof, plus all accumulated and
unpaid dividends thereon to the redemption date, if the Person formed by a
consolidation or amalgamation of the Company or into which the Company is merged
or to which the Company conveys, transfers or leases its properties and assets
substantially as an entirety is required, as a consequence of such
consolidation, amalgamation, merger, conveyance, transfer or lease and as a
consequence of a Change in Tax Law occurring after the date of such
consolidation, amalgamation, merger, conveyance, transfer or lease, to pay
Additional Amounts in respect of any tax, assessment or governmental charge
imposed on any Holder of Preferred Stock.

          (4) Payment of Additional Amounts.  If any deduction or withholding
              -----------------------------                                  
for any present or future taxes, assessments or other governmental charges of
(x) Bermuda or any political subdivision or governmental authority thereof or
therein having power to tax, (y) any jurisdiction, other than the United States,
from or through which payment on the Preferred Stock is made by the Company or a
successor corporation, or its paying agent in its capacity as such or any
political subdivision or governmental authority thereof or therein having the
power to tax or (z) any other jurisdiction, other than the United States, in
which the Company or a successor corporation is organized, or any political
subdivision or governmental authority thereof or therein having the power to tax
shall at any time be required by such jurisdiction (or any such political
subdivision or taxing authority) in respect of any amounts to be paid by the
Company or a successor corporation with respect to the Preferred Stock, the
Company or a successor corporation will pay to each Holder of Preferred Stock as
additional dividends, such additional amounts ("Additional Amounts") as may be
necessary in order that the net amounts paid to such holder of such Preferred
Stock who, with respect to any such tax, assessment or other governmental
charge, is not resident in, or a citizen of, such jurisdiction, after such
deduction or withholding, shall be not less than the amount specified in such
Preferred Stock to which such Holder is entitled; provided, however, that the
Company or a successor corporation shall not be required to make any payment 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 (or between a fiduciary, settlor,
          beneficiary, member or shareholder of, or possessor of a power over,
          such Holder, if such Holder is an estate, trust, partnership, limited
          liability company or corporation) and the taxing jurisdiction 

                                      66
<PAGE>
 
          or any political subdivision or territory or possession thereof or
          area subject to its jurisdiction, including, without limitation, such
          Holder (or such fiduciary, settlor, beneficiary, member, shareholder
          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 a permanent establishment therein, (b) the
          presentation of Preferred Stock (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, or (c) the
          presentation of Preferred Stock for payment in Bermuda or any
          political subdivision thereof or therein, unless such Preferred Stock
          could not have been presented for payment elsewhere;

            (ii) 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
          payable otherwise than by withholding from payment of the Liquidation
          Preference of or any dividends on the Preferred Stock;

            (iv) 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 Preferred Stock to comply with a request of
          the Company addressed to the Holder (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; or

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

nor shall Additional Amounts be paid with respect to any payment of the
Liquidation Preference of or dividends on any Preferred Stock to any Holder who
is a fiduciary or partnership or limited liability company or other than the
sole beneficial owner of such payment to the extent such payment would be
required by the laws of (x) Bermuda or any political subdivision or governmental
authority thereof or therein having the power to tax, (y) any jurisdiction,
other than the United States, from or through which payment on the Preferred
Stock is made by the Company or a successor corporation, or its paying agent in
its capacity as such or any political subdivision or governmental authority
thereof or therein having the power to tax or (z) any other jurisdiction, other
than the United States, in which the Company or a successor corporation is
organized, or any political subdivision or governmental authority thereof or
therein having the power to tax to be included in the income for tax purposes of
a beneficiary or settlor with respect to such fiduciary or a member of such
partnership, limited liability company or beneficial owner 

                                      67
<PAGE>
 
who would not have been entitled to such Additional Amounts had it been the
Holder of such Preferred Stock.

          The Company shall provide the Transfer Agent with the official
acknowledgment of the relevant taxing authority (or, if such acknowledgment is
not available, a certified copy thereof) evidencing the payment of the
withholding taxes, if any, by the Company. Copies of such documentation shall be
made available to the Holders of the Preferred Stock or the Transfer Agent, as
applicable, upon request therefor.

          All references herein to dividends on the Preferred Stock shall
include any Additional Amounts payable by the Company in respect of such
Preferred Stock.

          (g) VOTING RIGHTS.
              ------------- 

              (1) Holders of record of the Preferred Stock will have no voting
rights, except as required by law and as provided herein.  Upon:  (i) the
accumulation of unpaid dividends (and, if beginning on June 1, 2002 such
dividends are not paid in cash) on the outstanding Preferred Stock in an amount
equal to three semi-annual dividend payments (whether or not consecutive); (ii)
failure by the Company to satisfy any repurchase obligation (including, without
limitation, pursuant to any required Change of Control Offer) or mandatory
redemption obligation with respect to the Preferred Stock; (iii) failure by the
Company to comply with the provisions described under paragraph (i)(1); (iv)
failure by the Company for 60 days after notice by any Holder to comply with any
of its other agreements applicable to the Preferred Stock set forth herein; or
(v) 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 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, which default 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
the maturity of which has been so accelerated, aggregates $25.0 million or more
(each of the events described in the immediately preceding clauses (i) - (v)
being referred to herein as a "Voting Rights Triggering Event"); then the
Holders of a majority of the then outstanding shares of Preferred Stock, voting
as a separate single class, will be entitled to elect two members to the
Company's Board of Directors and the number of members of the Company's Board of
Directors will immediately and automatically be increased by two.  Voting rights
arising as a result of a Voting Rights Triggering Event will continue until such
time as all dividends in arrears on the Preferred Stock are paid in full and all
other Voting Rights Triggering Events have been cured or waived by the Holders
of at least a majority of the then outstanding shares of Preferred Stock, at
which time the term of office of any such members of the Company's Board of
Directors so elected shall terminate and such directors shall be deemed to have
resigned.

              (2) In addition to the provisions described above under paragraph
(c), the Company will not, without the approval of the Holders of at least two-
thirds of the then outstanding shares of Preferred Stock, amend, alter or repeal
any of the provisions of the 

                                      68
<PAGE>
 
Company's Bye-laws (or the Memorandum of Increase) so as to adversely affect the
powers, preferences or rights of the Holders of the Preferred Stock, or reduce
the time for any notice to which the Holders of the Preferred Stock may be
entitled. Subject to the provisions described above under paragraph (c), an
amendment thereof (or of the Memorandum of Increase) solely to authorize or
create, or to increase the amount of Junior Securities, Parity Securities or
Senior Securities, shall not be deemed to adversely affect the powers,
preferences or rights of the Holders of the Preferred Stock.

            (h) EXCHANGE.
                -------- 

                (1) The Company may, at its option, on any Dividend Payment
Date, exchange, in whole, but not in part, all then outstanding shares of
Preferred Stock for Exchange Notes with a principal amount equal to the then
effective Liquidation Preference of the Preferred Stock; provided that (i) on
the date of such exchange there are no accumulated and unpaid dividends on the
Preferred Stock (including the dividend payable on such date) or other
contractual impediments to such exchange; and (ii) immediately after giving
effect to such exchange, no Default or Event of Default under the Indenture or
the Senior Notes Indenture (in each case as defined therein) would exist or be
caused thereby.

                (2) Upon any exchange pursuant to the preceding paragraph,
Holders of Preferred Stock will be entitled to receive $1.00 principal amount of
Exchange Notes for each $1.00 of the then effective Liquidation Preference per
share of Preferred Stock held by such Holders. The Exchange Notes will be issued
in registered form, without coupons and will be issued in principal amounts of
$1,000 and integral multiples thereof (to the extent possible) so that the
Holders of Preferred Stock will receive certificates representing the entire
amount of Exchange Notes to which the Holders of Preferred Stock are entitled;
provided that the Company may pay cash in lieu of issuing Exchange Notes having
a principal amount less than $1,000.

                (3) Notice of the intention to exchange the Preferred Stock into
Exchange Notes will be sent by or on behalf of the Company not more than 60 nor
less than 30 days prior to the date of exchange (the "Exchange Date"), by first
class mail, postage prepaid, to each holder of record of Preferred Stock at its
registered address.  In addition to any information required by law or by the
applicable rules of any exchange upon which the Preferred Stock may then be
listed or admitted to trading, such notice will state:  (i) the Exchange Date;
(ii) the place or places where certificates for such shares are to be
surrendered for exchange, including any procedures applicable to exchanges to be
accomplished through book-entry transfers; and (iii) that dividends on the
Preferred Stock to be exchanged will cease to accumulate on the Exchange Date.
If notice of any exchange has been properly given, and if on or before the
Exchange Date the Exchange Notes have been duly executed and authenticated and
deposited with the Transfer Agent, then on and after the close of business on
the Exchange Date, the Preferred Stock to be exchanged will no longer be deemed
to be outstanding and may thereafter be issued in the same manner as the other
authorized but unissued preferred stock of the Company, but not as Preferred
Stock, and all rights of the Holders thereof as shareholders of the Company will
cease, except the right of such Holders to receive upon surrender of their
certificates the Exchange Notes and all accrued and unpaid interest thereon.

            (i) REPURCHASE AT THE OPTION OF HOLDERS.
                ----------------------------------- 

               (1) Change of Control.
                   ----------------- 

               (i) Upon the occurrence of a Change of Control, each Holder of
Preferred Stock will have the right to require the Company to purchase all or
any part of such Holder's Preferred Stock pursuant to the offer described below
(the "Change of Control Offer") at a purchase price in cash (the "Change of
Control Payment") equal to 101% of the then effective Liquidation Preference
thereof, plus all accumulated and unpaid dividends thereon to the date of
purchase (subject to the right of Holders of record on the relevant record date
to receive dividends due on the relevant Dividend Payment Date); provided,
however, that the Company shall not be obligated to repurchase Preferred Stock
pursuant to this covenant in the event that it has exercised its rights to
redeem all of the Preferred Stock as described under paragraph (f)(1). Within 30
days following any Change of Control, the Company will mail a notice to each
Holder describing the transaction or transactions that constitute the Change of
Control and offering to purchase such Holder's Preferred Stock on the date
specified in such notice, which date shall be no earlier than 30 and no later
than 60 days from the date such notice is mailed (the "Change of Control Payment
Date"), in accordance with the procedures required herein and described in such
notice.

              (ii) The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations to the
extent such laws and regulations are applicable in connection with the purchase
of Preferred Stock as a result of a Change of Control. To the extent that the
provisions of any securities laws or regulations conflict with any of the
provisions of this covenant, the Company will comply with the applicable
securities laws and regulations and will be deemed not to have breached its
obligations under this covenant by virtue thereof.

             (iii) On the Change of Control Payment Date, the Company will, to
the extent lawful, (A) accept for payment all Preferred Stock properly tendered
pursuant to the Change of Control Offer, (B) deposit with the Transfer Agent an
amount equal to the Change of Control Payment in respect of the Preferred Stock
so tendered and (C) deliver or cause to be delivered to the Transfer Agent
Preferred Stock so accepted together with an Officers' Certificate stating the
aggregate Liquidation Preference of Preferred Stock being purchased by the
Company. The Transfer Agent will promptly mail or deliver to each Holder of
Preferred Stock so tendered the Change of Control Payment for such Preferred
Stock, and the Transfer Agent will promptly countersign and mail or deliver (or
cause to be transferred by book-entry) to each Holder new Preferred Stock equal
in Liquidation Preference to any unpurchased portion of Preferred Stock
surrendered, if any. 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.

              (iv) The Company will not be required to make a Change of Control
Offer upon the occurrence of 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 herein 

                                       70
<PAGE>
 
applicable to a Change of Control Offer made by the Company, and purchases all
Preferred Stock validly tendered and not withdrawn under such Change of Control
Offer.

               (2) Asset Sales.
                   ----------- 

                (i) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale,
unless (A) the Company (or such Restricted Subsidiary, as the case may be)
receives consideration at the time of such Asset Sale at least equal to the fair
market value (as determined in good faith by the Board of Directors (including
as to the value of all noncash consideration) and set forth in an Officer's
Certificate delivered to the Transfer Agent) of the assets or Equity Interests
issued or sold or otherwise disposed of and (B) at least 75% of the
consideration therefor is in the form of cash and/or Cash Equivalents and (C)
the Net Proceeds received by the Company (or such Restricted Subsidiary, as the
case may be) from such Asset Sale are applied within 360 days following the
receipt of such Net Proceeds (1) first, to the extent the Company (or such
Restricted Subsidiary, as the case may be) elects, to the redemption or
repurchase of outstanding Indebtedness and (2) to the extent of the balance of
such Net Proceeds after application as described in (1) above and to the extent
the Company (or such Restricted Subsidiary, as the case may be) elects, to
reinvest, or enter into a legally binding agreement to reinvest, such Net
Proceeds (or any portion thereof) in assets that are used or useful in a
Permitted Business. The balance of such Net Proceeds, after the application of
such Net Proceeds as described in the immediately preceding clauses (1) and (2),
shall constitute "Excess Proceeds."

                (ii) When the aggregate amount of Excess Proceeds equals or
exceeds $15.0 million (taking into account income earned on such Excess
Proceeds), the Company will be required to make an offer to all Holders of
Preferred Stock (an "Asset Sale Offer") to purchase the maximum Liquidation
Preference of Preferred Stock that may be purchased out of the Excess Proceeds,
at a purchase price in cash in an amount equal to 100% of the effective
Liquidation Preference thereof, plus all accumulated and unpaid dividends
thereon to the date of purchase, in accordance with the procedures set forth
herein. To the extent that any Excess Proceeds remain after consummation of an
Asset Sale Offer, the Company may use such Excess Proceeds at its discretion. If
the aggregate Liquidation Preference of Preferred Stock tendered into such Asset
Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds,
the Transfer Agent shall select the Preferred Stock to be purchased on a pro
rata basis. Upon completion of such Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero for purposes of the first sentence of this
paragraph.

                (iii) The amount of (x) any liabilities (as shown on the
Company's (or such Restricted Subsidiary's, as the case may be) most recent
balance sheet) of the Company or any Restricted Subsidiary (other than
contingent liabilities) that are assumed by the transferee of any such assets
pursuant to an agreement that releases the Company or any Restricted Subsidiary
from all liability in respect thereof, (y) Indebtedness of any Restricted
Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset
Sale, to the extent that the Company and each other Restricted Subsidiary are
released from any guarantee of payment of the principal amount of such
Indebtedness in connection with such Asset Sale and (z) any securities, notes or

                                      71
<PAGE>
 
other obligations received by the Company (or such Restricted Subsidiary, as the
case may be) from such transferee that are contemporaneously (subject to
ordinary settlement periods) converted by the Company (or such Restricted
Subsidiary, as the case may be) into cash and/or Cash Equivalents (to the extent
of the cash and/or Cash Equivalents received), will be deemed to be cash and/or
Cash Equivalents for purposes of this
provision.

            (j) COVENANTS.
                --------- 

               (1) Restricted Payments

                   (i) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly: (A) declare or pay any
dividend or make any other payment or distribution on account of the Company's
or any of its Restricted Subsidiaries' Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation involving
the Company or any of its Restricted Subsidiaries) or to the direct or indirect
Holders of the Company's or any of its Restricted Subsidiaries' Equity Interests
(other than dividends or distributions payable in Equity Interests (other than
Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary
of the Company); (B) purchase, redeem or otherwise acquire or retire for value
(including, without limitation, in connection with any merger or consolidation
involving the Company) any Equity Interests of the Company or any direct or
indirect parent of the Company (other than any such Equity Interests owned by
the Company or any Wholly Owned Restricted Subsidiary of the Company); (C) make
any payment on or with respect to, or purchase, redeem, defease or otherwise
acquire or retire for value any Junior Securities (other than dividends or
distributions payable in Junior Securities (other than Disqualified Stock) of
the Company or to the Company or a Restricted Subsidiary of the Company); or (D)
make any Restricted Investment (all such payments and other actions set forth in
clauses (A) through (D) above being collectively referred to as "Restricted
Payments"), unless:

                           (1) at the time of and after giving effect to such
            Restricted Payment, no Voting Rights Triggering Event shall have
            occurred and be continuing or would occur as a consequence thereof;

                           (2) in the case of paragraph (j)(1)(i)(A), (B) or
            (C), and, in the case of any Restricted Investment that is not an
            Investment in a Permitted Business, the Company would, at the time
            of such Restricted Payment and after giving pro forma effect thereto
            as if such Restricted Payment had been made at the beginning of the
            applicable four-quarter period, have been permitted to incur at
            least $1.00 of additional Indebtedness pursuant to either paragraphs
            (j)(2)(A)(1) or (2); and

                           (3) such Restricted Payment, together with the
            aggregate amount of all other Restricted Payments made by the
            Company and its Restricted Subsidiaries and any Permitted
            Investments made pursuant to clause (h) of the definition of
            Permitted Investments after the date hereof (excluding Restricted
            Payments permitted by paragraphs (j)(1)(ii)(C), (D), (E), (G), (H)
            and (I) but, in

                                       72
<PAGE>
 
            the case of clause (H), only to the extent that such Restricted
            Payments are reflected as an expense on the income statement of
            GCL), is less than the sum, without duplication, of (i) the
            remainder of (x) 100% of the cumulative Consolidated Cash Flow (or,
            in the case Consolidated Cash Flow shall be negative, less 100% of
            such deficit) from the Issue Date through the last day of the last
            full fiscal quarter immediately preceding such Restricted Payment
            minus (y) the product of 1.5 times the cumulative Consolidated
            Interest Expense from the date hereof through the last day of the
            last full fiscal quarter immediately preceding such Restricted
            Payment, plus (ii) 100% of the aggregate net cash proceeds and the

including, without limitation, for sale, lease, transfer, conveyance or other
disposition to any customer of the Company or any Restricted Subsidiary shall

the sale, lease, transfer, conveyance or other disposition of "all or

interpreting the phrase "substantially all," there is no precise established
definition of such phrase under applicable law. Accordingly, the ability of a
Holder of Notes to require the Company to purchase such Notes as a result of a
sale, lease, transfer, conveyance or other disposition of less than all of the
assets of GCL or the Company and its Restricted Subsidiaries taken as a whole to
another Person or group may be uncertain.

the foregoing requirements as an Unrestricted Subsidiary, it shall thereafter
cease to be an Unrestricted Subsidiary for purposes of the Indenture and any
Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted
Subsidiary of the Company as of such date (and, if such Indebtedness is not
permitted to be incurred as of such date under Section 4.09 hereof, the Company
shall be in default of Section 4.09 hereof). The Board of Directors of the
Company may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that such designation shall be deemed to be an incurrence
of Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (i) such Indebtedness is permitted under Section 4.09 hereof,
calculated on a pro forma basis as if such designation had occurred at the
beginning of the four-quarter reference period, and (ii) no Default or Event of
Default would be in existence following such designation.  As of the Issue Date,
all of the Company's Subsidiaries will be Restricted Subsidiaries, except for
the PC-1 Companies, and the AC Subsidiaries may not be designated as
Unrestricted Subsidiaries unless and until the PC-1 Companies are designated as
Restricted Subsidiaries.

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

          "Weighted Average Life to Maturity" means, when applied to any
Indebtedness at any date, the number of years obtained by dividing (i) the sum
of the products obtained by multiplying (a) the amount of each then remaining
installment, sinking fund, serial maturity or other required payments of
principal, including payment at final maturity, in respect thereof, by (b) the
number of years (calculated to the nearest one-twelfth) that will elapse between
such date and the making of such payment, by (ii) the then outstanding principal
amount of such Indebtedness.

          "Wholly Owned Restricted Subsidiary" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock or other
ownership interests of which (other than directors' qualifying shares) shall at
the time be owned by such Person or by one or more Wholly Owned

Section 2.01.  Form and Dating.

     (a)  General.

          The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibits A-1 and A-2 hereto.  The Notes may have
                             ------------     --                             
notations, legends or endorsements required by law, stock exchange rule or usage
or agreements to which the Company is subject.  Each Note shall be dated the
date of its authentication.  The Notes shall be in denominations of $1,000 and
integral multiples thereof.

          The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.  However, to the extent any
provision of any Note conflicts with the express provisions of this Indenture,
the provisions of this Indenture shall govern and be controlling.

     (b)  Global Notes.

          Notes issued in global form shall be substantially in the form of
Exhibits A-1 or A-2 attached hereto (including the Global Note Legend thereon
- ------------    ---                                                          
and the "Schedule of Exchanges of Interests in the Global Note" attached
thereto).  Notes issued in definitive form shall be substantially in the form of
Exhibit A-1 attached hereto (but without the Global Note Legend thereon and
- -----------                                                                
without the "Schedule of Exchanges of Interests in the Global Note" attached
thereto).  Each Global Note shall represent such of the outstanding Notes as
shall be specified therein and each shall provide that it shall represent the
aggregate principal amount of outstanding Notes from time to time endorsed
thereon and that the aggregate principal amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions.  Any endorsement of a Global Note to reflect
the amount of any increase or decrease in the aggregate principal amount of
outstanding Notes represented thereby shall be made by the Trustee or the Note
Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.06 hereof.

     (c)  Temporary Global Notes.

          Notes offered and sold in reliance on Regulation S shall be issued
initially in the form of the Regulation S Temporary Global Note, which shall be
deposited on behalf of the purchasers of the Notes, presented thereby with the
Trustee, at its New York office, as custodian for the Depository, and registered
in the name of the Depositary or the nominee of the Depositary for the accounts
of the designated agents holding on behalf of Euroclear or CEDEL Bank, duly
executed by the Company and authenticated by the Trustee as hereinafter
provided.  The Restricted Period shall be terminated upon the receipt by the
Trustee of (i) a written certificate from the Depositary, together with copies
of certificates from Euroclear and CEDEL Bank certifying that they have received
certification of non United States beneficial ownership of 100% of the aggregate
principal amount of the Regulation S Temporary Global Note (except to the extent
of any beneficial owners thereof who acquired an interest therein during the
Restricted Period pursuant to another exemption from registration under the
Securities Act and who will 

                                       20
<PAGE>
 
take delivery of a beneficial ownership interest in a 144A Global Note or an IAI
Global Note bearing a Private Placement Legend, all as contemplated by Section
2.06(a)(ii) hereof), and (ii) an Officer's Certificate from the Company.
Following the termination of the Restricted Period, beneficial interests in the
Regulation S Temporary Global Note shall be exchanged for beneficial interests
in Regulation S Permanent Global Notes pursuant to the Applicable Procedures.
Simultaneously with the authentication of Regulation S Permanent Global Notes,
the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate
principal amount of the Regulation S Temporary Global Note and the Regulation S
Permanent Global Notes may from time to time be increased or decreased by
adjustments made on the records of the Trustee and the Depositary or its
nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

     (d) Euroclear and CEDEL Procedures Applicable.  The provisions of the
"Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of CEDEL Bank"
and "Customer Handbook" of CEDEL Bank shall be applicable to transfers of
beneficial interests in the Regulation S Temporary Global Note and the
Regulation S Permanent Global Notes that are held by Participants through
Euroclear or CEDEL Bank.

Section 2.02.  Execution and Authentication.

          Two Officers shall sign the Notes for the Company by manual or
facsimile signature.

          If an Officer whose signature is on a Note no longer holds that office
at the time a Note is authenticated, the Note shall nevertheless be valid.

          A Note shall not be valid until authenticated by the manual signature
of the Trustee.  The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

          The Trustee shall, upon a written order of the Company signed by two
Officers (an "Authentication Order"), authenticate Notes for original issue up
to the aggregate principal amount stated in paragraph 4 of the Notes.  The
aggregate principal amount of Notes outstanding at any time may not exceed such
amount except as provided in Section 2.07 hereof.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes.  An authenticating agent may authenticate Notes
whenever the Trustee may do so.  Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.  An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

Section 2.03.  Registrar and Paying Agent.

          The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent").  The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents.  The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent.  The Company may change any
Paying Agent or Registrar without notice to any Holder.  The Company shall
notify the Trustee in writing of the name and address of any Agent not a party
to this Indenture.  If the Company fails to appoint or maintain another entity
as Registrar or Paying

                                       21
<PAGE>
 
Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may
act as Paying Agent or Registrar.

          The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Notes.

          The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

          The Trustee is authorized to enter into a letter of representations
with DTC in the form provided to the Trustee by the Company and to act in
accordance with such letter.

Section 2.04.  Paying Agent to Hold Money in Trust.

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Special Interest, if any, or interest on the Notes, and
will notify the Trustee of any default by the Company in making any such
payment.  While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee.  The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee.  Upon payment
over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money.  If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent.  Upon
any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Notes.

Section 2.05.  Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA (S) 312(a).  If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Company shall otherwise comply with TIA (S) 312(a).

Section 2.06.  Transfer and Exchange.

          (a) Transfer and Exchange of Global Notes.

          A Global Note may not be transferred as a whole except by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary.
All Global Notes will be exchanged by the Company for Definitive Notes if (i)
the Company delivers to the Trustee notice from the Depositary that it is
unwilling or unable to continue to act as Depositary or that it is no longer a
clearing agency registered under the Exchange Act and, in either case, a
successor Depositary is not appointed by the Company within 120 days after the
date of such notice from the Depositary or (ii) the Company in its sole
discretion determines that the Global Notes (in whole but not in part) should be
exchanged for Definitive Notes and delivers a written notice to 

                                       22
<PAGE>
 
such effect to the Trustee; provided that in no event shall the Regulation S
Temporary Global Note be exchanged by the Company for Definitive Notes prior to
(x) the expiration of the Restricted Period and (y) the receipt by the Registrar
of any certificates determined by the Company to be required pursuant to Rule
903(c)(3)(ii)(B) under the Securities Act. Upon the occurrence of either of the
preceding events in (i) or (ii) above, Definitive Notes shall be issued in such
names as the Depositary shall instruct the Trustee. Global Notes also may be
exchanged or replaced, in whole or in part, as provided in Sections 2.07 and
2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu
of, a Global Note or any portion thereof, pursuant to this Section 2.06 or
Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form
of, and shall be, a Global Note. A Global Note may not be exchanged for another
Note other than as provided in this Section 2.06(a), however, beneficial
interests in a Global Note may be transferred and exchanged as provided in
Section 2.06(b),(c) or (f) hereof.

          (b) Transfer and Exchange of Beneficial Interests in the Global Notes.

          The transfer and exchange of beneficial interests in the Global Notes
shall be effected through the Depositary, in accordance with the provisions of
this Indenture and the Applicable Procedures.  Beneficial interests in the
Restricted Global Notes shall be subject to restrictions on transfer comparable
to those set forth herein to the extent required by the Securities Act.
Transfers of beneficial interests in the Global Notes also shall require
compliance with either subparagraph (i) or (ii) below, as applicable, as well as
one or more of the other following subparagraphs, as applicable:

     (i) Transfer of Beneficial Interests in the Same Global Note.  Beneficial
  interests in any Restricted Global Note may be transferred to Persons who take
  delivery thereof in the form of a beneficial interest in the same Restricted
  Global Note in accordance with the transfer restrictions set forth in the
  Private Placement Legend; provided, however, that prior to the expiration of
  the Restricted Period, transfers of beneficial interests in the Temporary
  Regulation S Global Note may not be made to a U.S. Person or for the account
  or benefit of a U.S. Person (other than an Initial Purchaser).  Beneficial
  interests in any Unrestricted Global Note may be transferred to Persons who
  take delivery thereof in the form of a beneficial interest in an Unrestricted
  Global Note.  No written orders or instructions shall be required to be
  delivered to the Registrar to effect the transfers described in this Section
  2.06(b)(i).

     (ii) All Other Transfers and Exchanges of Beneficial Interests in Global
  Notes.  In connection with all transfers and exchanges of beneficial interests
  that are not subject to Section 2.06(b)(i) above, the transferor of such
  beneficial interest must deliver to the Depositary either (A) (1) a written
  order from a Participant or an Indirect Participant given to the Depositary in
  accordance with the Applicable Procedures directing the Depositary to credit
  or cause to be credited a beneficial interest in another Global Note in an
  amount equal to the beneficial interest to be transferred or exchanged and (2)
  instructions given in accordance with the Applicable Procedures containing
  information regarding the Participant account to be credited with such
  increase or (B) (1) a written order from a Participant or an Indirect
  Participant given to the Depositary in accordance with the Applicable
  Procedures directing the Depositary to cause to be issued a Definitive Note in
  an amount equal to the beneficial interest to be transferred or exchanged and
  (2) instructions given by the Depositary to the Registrar containing
  information regarding the Person in whose name such Definitive Note shall be
  registered to effect the transfer or exchange referred to in (1) above,
  provided that, in no event shall Definitive Notes be issued upon the transfer
  or exchange of beneficial interests in the Regulation S Temporary Global Note
  prior to (x) the expiration of the Restricted Period and (y) the receipt by
  the Registrar of any certificates determined by the Company to be 

                                       23
<PAGE>
 
  required pursuant to Rule 903 under the Securities Act. Upon consummation of
  an Exchange Offer by the Company in accordance with Section 2.06(f) hereof,
  the requirements of this Section 2.06(b)(ii) shall be deemed to have been
  satisfied upon receipt by the Registrar of the instructions contained in the
  Letter of Transmittal delivered by the Holder of such beneficial interests in
  the Restricted Global Notes. Upon satisfaction of all of the requirements for
  transfer or exchange of beneficial interests in Global Notes contained in this
  Indenture and the Notes or otherwise applicable under the Securities Act, the
  Trustee shall adjust the principal amount of the relevant Global Note(s)
  pursuant to Section 2.06(h) hereof.

     (iii)  Transfer of Beneficial Interests to Another Restricted Global Note.
  A beneficial interest in any Restricted Global Note may be transferred to a
  Person who takes delivery thereof in the form of a beneficial interest in
  another Restricted Global Note if the transfer complies with the requirements
  of Section 2.06(b)(ii) above and the Registrar receives the following:

          (A) if the transferee will take delivery in the form of a beneficial
       interest in the 144A Global Note, then the transferor must deliver a
       certificate in the form of Exhibit B hereto, including the certifications
                                  ---------                                     
       in item (1) thereof; and

          (B) if the transferee will take delivery in the form of a beneficial
       interest in the Regulation S Temporary Global Note or the Regulation S
       Global Note, then the transferor must deliver a certificate in the form
       of Exhibit B hereto, including the certifications in item (2) thereof;
          ---------                                                          
       and

          (C) if the transferee will take delivery in the form of a beneficial
       interest in the IAI Global Note, then the transferor must deliver a
       certificate in the form of Exhibit B hereto, including the certifications
                                  ---------                                     
       and certificates and Opinion of Counsel required by item (3) thereof, if
       applicable.

     (iv) Transfer and Exchange of Beneficial Interests in a Restricted Global
  Note for Beneficial Interests in the Unrestricted Global Note.  A beneficial
  interest in any Restricted Global Note may be exchanged by any holder thereof
  for a beneficial interest in an Unrestricted Global Note or transferred to a
  Person who takes delivery thereof in the form of a beneficial interest in an
  Unrestricted Global Note if the exchange or transfer complies with the
  requirements of Section 2.06(b)(ii) above and:

          (A) such exchange or transfer is effected pursuant to the Exchange
       Offer in accordance with the Registration Agreement and the holder of the
       beneficial interest to be transferred, in the case of an exchange, or the
       transferee, in the case of a transfer, certifies in the applicable Letter
       of Transmittal or via the Depositary's book-entry system that it is not
       (1) a broker-dealer, (2) a Person participating in the distribution of
       the Exchange Notes or (3) a Person who is an affiliate (as defined in
       Rule 144) of the Company;

          (B) such transfer is effected pursuant to the Shelf Registration
       Statement in accordance with the Registration Agreement;

                                       24
<PAGE>
 
          (C) such transfer is effected by a Restricted Broker-Dealer pursuant
       to the Exchange Offer Registration Statement in accordance with the
       Registration Agreement; or

          (D) the Registrar receives the following:

            (1) if the holder of such beneficial interest in a Restricted Global
     Note proposes to exchange such beneficial interest for a beneficial

          (h) Cancellation and/or Adjustment of Global Notes.

          At such time as all beneficial interests in a particular Global Note
have been exchanged for Definitive Notes or a particular Global Note has been
redeemed, repurchased or canceled in whole and not in part, each such Global
Note shall be returned to or retained and canceled by the Trustee in accordance
with Section 2.11 hereof.  At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in another
Global Note or for Definitive Notes, the principal amount of Notes represented
by such Global Note shall be reduced accordingly and an endorsement shall be
made on such Global Note by the Trustee or by the Depositary at the direction of
the Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note
shall be increased accordingly and an endorsement shall be made on such Global
Note by the Trustee or by the Depositary at the direction of the Trustee to
reflect such increase.

          (i) General Provisions Relating to Transfers and Exchanges.

     (i) To permit registrations of transfers and exchanges, the Company shall
  execute and the Trustee shall authenticate Global Notes and Definitive Notes
  upon the Company's order or at the Registrar's request.

     (ii) No service charge shall be made to a holder of a beneficial interest
  in a Global Note or to a Holder of a Definitive Note for any registration of
  transfer or exchange, but the Company may require payment of a sum sufficient
  to cover any transfer tax or similar governmental charge payable in connection
  therewith (other than any such transfer taxes or similar governmental charge
  payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.11, 4.10,
  4.15 and 9.05 hereof).

     (iii)  The Registrar shall not be required to register the transfer of or
  exchange any Note selected for redemption in whole or in part, except the
  unredeemed portion of any Note being redeemed in part.

     (iv) All Global Notes and Definitive Notes issued upon any registration of
  transfer or exchange of Global Notes or Definitive Notes shall be the valid
  obligations of the Company, evidencing the same debt, and entitled to the same
  benefits under this Indenture, as the Global Notes or Definitive Notes
  surrendered upon such registration of transfer or exchange.

     (v) The Company shall not be required (A) to issue, to register the
  transfer of or to exchange any Notes during a period beginning at the opening
  of business 15 days before the day of the mailing of notice of redemption
  under Section 3.02 hereof and ending at the close of business on such day, (B)
  to register the transfer of or to exchange any Note so selected for redemption
  in whole or in part, except the unredeemed portion of any Note being redeemed
  in part or (c) to register the transfer of or to exchange a Note between a
  record date and the next succeeding Interest Payment Date.

     (vi) Prior to due presentment for the registration of a transfer of any
  Note, the Trustee, any Agent and the Company may deem and treat the Person in
  whose name any Note is registered as the 

                                       33
<PAGE>
 
  absolute owner of such Note for the purpose of receiving payment of principal
  of and interest on such Notes and for all other purposes, and none of the
  Trustee, any Agent or the Company shall be affected by notice to the contrary.

     (vii)  The Trustee shall authenticate Global Notes and Definitive Notes in
  accordance with the provisions of Section 2.02 hereof.

     (viii)  All certifications, certificates and Opinions of Counsel required
  to be submitted to the Registrar pursuant to this Section 2.06 to effect a
  registration of transfer or exchange may be submitted by facsimile.

     (ix) Each Holder of a Note agrees to indemnify the Trustee and the
  Registrar against any liability that may result from the transfer, exchange or
  assignment of such Holder's Note in violation of any provision of this
  Indenture and/or applicable United States federal or state securities law.

     (x) Neither the Trustee nor the Registrar shall have any obligation or duty
  to monitor, determine or inquire as to compliance with any restrictions on
  transfer imposed under this Indenture or under applicable law with respect to
  any transfer of any interest in any Note (including any transfers between or
  among Participants or beneficial owners of interests in any Global Note) other
  than to require delivery of such certificates and other documentation or
  evidence as are expressly required by, and to do so if and when expressly
  required by the terms of, this Indenture, and to examine the same to determine
  substantial compliance as to form with the express requirements hereof.

Section 2.07.  Replacement Notes

          If any mutilated Note is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met.  If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced.  The Company may charge for its expenses in replacing a Note.

          Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

Section 2.08.  Outstanding Notes.

          The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding.  Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; however, Notes held by the Company or a Subsidiary of
the Company shall not be deemed to be outstanding for purposes of Section
3.07(b) hereof.

                                       34
<PAGE>
 
          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser or protected purchaser.

          If the principal amount of any Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

          If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

Section 2.09.  Treasury Notes.

          In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.10.  Temporary Notes

          Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Notes.  Temporary Notes shall be substantially in
the form of certificated Notes but may have variations that the Company
considers appropriate for temporary Notes and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Notes in exchange for temporary Notes.

          Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

Section 2.11.  Cancellation.

          The Company at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee and no one else shall cancel all Notes surrendered for registration
of transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Notes (subject to the record retention requirements of the Exchange
Act).  Certification of the destruction of all canceled Notes shall be delivered
to the Company.  The Company may not issue new Notes to replace Notes that it
has paid or that have been delivered to the Trustee for cancellation.

Section 2.12.  Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof.  The Company shall notify the Trustee
in writing of the amount of defaulted interest proposed to be paid on each Note
and the date of the proposed payment.  The Company

                                       35
<PAGE>
 
shall fix or cause to be fixed each such special record date and payment date,
provided that no such special record date shall be less than 10 days prior to
the related payment date for such defaulted interest. At least 15 days before
the special record date, the Company (or, upon the written request of the
Company, the Trustee in the name and at the expense of the Company) shall mail
or cause to be mailed to Holders a notice that states the special record date,
the related payment date and the amount of such interest to be paid.

Section 2.13.  CUSIP Numbers.

          The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Notes or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Notes, and any such redemption shall not be affected by any defect in or the
omission of such numbers.  The Company will promptly notify the Trustee of any
change in the CUSIP numbers.

                                  ARTICLE 3.
                           REDEMPTION AND PREPAYMENT

Section 3.01.  Notices to Trustee.

          If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed, (iv) the redemption price and (v) the CUSIP
numbers of the Notes to be redeemed.

Section 3.02.  Selection of Notes to Be Redeemed

          If less than all of the Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Notes to be redeemed
or purchased among the Holders of the Notes in compliance with the requirements
of the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a pro rata basis, by lot or in
accordance with any other method the Trustee considers fair and appropriate.  In
the event of partial redemption by lot, the particular Notes to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption.

          The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed.  Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed.  Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

Section 3.03.  Notice of Redemption

                                       36
<PAGE>
 
          Subject to the provisions of Section 3.11 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address.

         The notice shall identify the Notes to be redeemed and shall state:

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Note is being redeemed in part, the portion of the principal
amount of such Note to be redeemed and that, after the redemption date upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion shall be issued upon cancellation of the original Note;

     (d) the name and address of the Paying Agent;

     (e) that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (f) that, unless the Company defaults in making such redemption payment,
interest on Notes called for redemption ceases to accrue on and after the
redemption date;

     (g) the paragraph of the Notes and/or Section of this Indenture pursuant to
which the Notes called for redemption are being redeemed; and

     (h) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Notes.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

Section 3.04.  Effect of Notice of Redemption

          Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price.  A notice of redemption may not be
conditional.

Section 3.05.  Deposit of Redemption Price

          Prior to 10 a.m. on the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption
price of and accrued interest on all Notes to be redeemed on that date.  The
Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Notes to be redeemed.

                                       37
<PAGE>
 
          If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption.  If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date.  If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof.

Section 3.06.  Notes Redeemed in Part.

          Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

Section 3.07.  Optional Redemption.

          (a) Except as set forth in Sections 3.07(b) and (c) below and in
Section 3.08 hereof, the Notes shall not be redeemable at the Company's option
prior to December 1, 2003. Thereafter, the Notes shall be subject to redemption
at any time or from time to time at the option of the Company, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below, plus

applicable redemption date, if redeemed during the twelve-month period beginning

          2004......................................   103.500%
          2005......................................   101.750%
          2006 and thereafter.......................   100.000%


          (b) Notwithstanding the foregoing, at any time prior to December 1,
2001, the Company may, on any one or more occasions, redeem up to 35% of the
aggregate principal amount of Notes originally issued pursuant to this Indenture
at a redemption price of 110.500% of the principal amount thereof, plus accrued
and unpaid interest and Special Interest, if any, thereon to the redemption
date, with the net cash proceeds received from one or more Equity Offerings made
by the Company or GCL (to the extent such net cash proceeds received by GCL were
contributed to the Company as common equity capital); provided that at least 65%
of the aggregate principal amount of Notes originally issued pursuant to this
Indenture remain outstanding immediately after the occurrence of any such
redemption. The Company may make any such redemption upon not less than 30 nor
more than 60 days' notice (but in no event more than 90 days after the closing
of the related Equity Offering). Any such notice may be given prior to the
completion of the related Equity Offering and any such redemption may,

                                       38
<PAGE>
 
at the Company's discretion, be subject to the satisfaction of one or more
conditions precedent, including, but not limited to, the completion of the
related Equity Offering.

          (c) In addition, at any time prior to December 1, 2003, the Notes may
also be redeemed at the option of the Company, in whole but not in part, upon
the occurrence of a Change of Control, upon not less than 30 nor more than 60
days' prior notice (but in no event may any such redemption occur more than 90
days after the occurrence of such Change of Control) mailed by first-class mail
to each Holder's registered address, at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium as of, and accrued and
unpaid interest thereon to the date of redemption (the "Redemption Date").

          (d) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

Section 3.08.  Optional Tax Redemption

          The Notes will be subject to redemption at the option of the Company
or a successor corporation at any time, in whole but not in part, upon not less
than 30 nor more than 60 days' notice, at a redemption price equal to the
principal amount thereof, plus accrued and unpaid interest thereon to the
redemption date if, as a result of any change in or amendment to the laws or any
regulations or ruling promulgated thereunder of (x) Bermuda or any political
subdivision or governmental authority thereof or therein having the power to
tax, (y) any jurisdiction, other than the United States, from or through which
payment on the Notes is made by the Company or a successor corporation, or its
paying agent in its capacity as such or any political subdivision or
governmental authority thereof or therein having the power to tax or (z) any
other jurisdiction, other than the United States, in which the Company or a
successor corporation is organized, or any political subdivision or governmental
authority thereof or therein having the power to tax, or any change in the
official application or interpretation of such laws, regulations or rulings, or
any change in the official application or interpretation of, or any execution of
or amendment to, any treaty or treaties affecting taxation to which such
jurisdiction (or such political subdivision or taxing authority) is a party (a
"Change in Tax Law"), which becomes effective on or after the Issue Date, the
Company or a successor corporation is or would be required on the next
succeeding interest payment date to pay Additional Amounts with respect to the
Notes (as described under Section 3.09 hereof), and the payment of such
Additional Amounts cannot be avoided by the use of any reasonable measures
available to the Company or a successor corporation.

the Company at any time, in whole but not in part, upon not less than 30 nor
more than 60 days' notice, at a redemption price equal to the principal amount
thereof, plus accrued and unpaid interest thereon to the redemption date, if the

Additional Amounts in respect of any tax, assessment or governmental charge
imposed on any Holder of Notes.

Section 3.09.  Payment of Additional Amounts.

<PAGE>
 
          If any deduction or withholding for any present or future taxes,
assessments or other governmental charges of (x) Bermuda or any political
subdivision or governmental authority thereof or therein having power to tax,
(y) any jurisdiction, other than the United States, from or through which
payment on the Notes is made by the Company or a successor corporation, or its

corporation under the Notes, the Company or a successor corporation will pay to
each Holder of Notes as additional interest, such additional amounts
("Additional Amounts") as may be necessary in order that the net amounts paid to
such holder of such Notes who, with respect to any such tax, assessment or other
governmental charge, is not resident in, or a citizen of, such jurisdiction,
after such deduction or withholding, shall be not less than the amount specified
in such Notes to which such Holder is entitled; provided, however, that the
Company or a successor corporation shall not be required to make any payment of
Additional Amounts for or on account of:

     (a) Any tax, assessment or other governmental charge that would not have
been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership, limited liability company or corporation) and the
taxing jurisdiction or any political subdivision or territory or possession
thereof or area subject to its jurisdiction, including, without limitation, such

been present or engaged in a trade or business therein or having or having had a
permanent establishment therein, (ii) the presentation of a 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, or (iii) the
presentation of a Note for payment in Bermuda or any political subdivision
thereof or therein, unless such Note could not have been presented for payment
elsewhere;

part of such tax, assessment or other governmental charge; or

     (e) Any combination of items (a), (b), (c) and (d) above;

          nor shall Additional Amounts be paid with respect to any payment of
the principal of, or any premium or interest on, any Note to any Holder who is a

of the relevant taxing authority (or, if such acknowledgment is not available, a
certified copy thereof) evidencing the payment of the withholding taxes, if any,
by the Company. Copies of such documentation shall be made available to the
Holders of the Notes or the Paying Agent, as applicable, upon request therefor.

          All references in this Indenture to principal of, premium, if any, and

specified below.

          The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a

purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer.  Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

          If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Company shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee.  The notice shall contain

<PAGE>
 
all instructions and materials necessary to enable such Holders to tender Notes
pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all
Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall
state:

     (a) that the Asset Sale Offer is being made pursuant to this Section 3.11
and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain
open;

     (b) the Offer Amount, the purchase price and the Purchase Date;

     (c) that any Note not tendered or accepted for payment shall continue to
accrue interest;

     (d) that, unless the Company defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
interest after the Purchase Date;

     (e) that Holders electing to have a Note purchased pursuant to an Asset
Sale Offer may only elect to have all of such Note purchased and may not elect
to have only a portion of such Note purchased;

     (f) that Holders electing to have a Note purchased pursuant to any Asset
Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Company, a depositary, if appointed by
the Company, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;

     (g) that Holders shall be entitled to withdraw their election if the
Company, the depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

     (h) that, if the aggregate principal amount of Notes surrendered by Holders
exceeds the Offer Amount, the Company shall select the Notes to be purchased on
a pro rata basis (with such adjustments as may be deemed appropriate by the
Company so that only Notes in denominations of $1,000, or integral multiples
thereof, shall be purchased); and

     (i) that Holders whose Notes were purchased only in part shall be issued
new Notes equal in principal amount to the unpurchased portion of the Notes
surrendered (or transferred by book-entry transfer).

          On or before 10:00 a.m. on the Purchase Date, the Company shall, to
the extent lawful, accept for payment, on a pro rata basis to the extent
necessary, the Offer Amount or portions thereof tendered pursuant to the Asset
Sale Offer, or if less than the Offer Amount has been tendered, all Notes
tendered, and shall deliver to the Trustee an Officers' Certificate stating that
such Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 3.11.  The Company, the Depositary or
the Paying Agent, as the case may be, shall promptly (but in any case not later
than five days after the Purchase Date) mail or deliver to each tendering Holder
an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Company shall promptly issue a new
Note, and the Trustee, upon written request from the Company shall authenticate
and mail or deliver such new Note to such Holder, in a principal amount 

                                       42
<PAGE>
 
equal to any unpurchased portion of the Note surrendered. Any Note not so
accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company shall publicly announce the results of the Asset Sale Offer
on the Purchase Date.

          Other than as specifically provided in this Section 3.11, any purchase
pursuant to this Section 3.11 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

if any, and interest and Special Interest, if any, on the Notes on the dates and
in the manner provided in the Notes.  Principal, premium, if any, and interest
and Special Interest, if any, shall be considered paid on the date due if the
Paying Agent, if other than the Company or a Subsidiary thereof, holds as of

demands to or upon the Company in respect of the Notes and this Indenture may be
served.  The Company shall give prompt written notice to the Trustee of the

all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes.  The Company shall give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.

signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture (or, if a Default or
Event of Default shall have occurred, describing all such Defaults or Events of
Default of which he or she may have knowledge and what action the Company is
taking or proposes to take with respect thereto) and that to the best of his or

understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

respect to the Holders of the Notes.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, consummate any Asset Sale, unless (i)
the Company (or such Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (as determined in good faith by the Board of Directors (including as to
the value of all noncash consideration) and set forth in an Officer's
Certificate delivered to the Trustee) of the assets or Equity Interests issued
or sold or otherwise disposed of and (ii) at least 75% of the consideration
therefor is in the form of cash and/or Cash Equivalents, and (iii) the Net
Proceeds received by the Company (or such Restricted Subsidiary, as the case may
be) from such Asset Sale are applied within 360 days following the receipt of
such Net Proceeds (a) first, to the extent the Company (or such Restricted
Subsidiary, as the case may be) elects, to the redemption or repurchase of
outstanding Senior Debt and (b) to the extent of the balance of such Net
Proceeds after application as described in (a) above and to the extent the
Company (or such Restricted Subsidiary, as the case may be) elects, to reinvest,
or enter into a legally binding agreement to reinvest, such Net Proceeds (or any
portion thereof) in assets that are used or useful in a Permitted Business.  The
balance of such Net Proceeds, after the application of such Net Proceeds as
described in the immediately preceding clauses (a) and (b), shall constitute
"Excess Proceeds."

                                       50
<PAGE>
 
          When the aggregate amount of Excess Proceeds equals or exceeds $15.0
million (taking into account income earned on such Excess Proceeds), the Company
will be required to make an offer to all Holders of Notes and pari passu
Indebtedness (an "Asset Sale Offer") to purchase the maximum principal amount of
Notes and pari passu Indebtedness that may be purchased out of the Excess
Proceeds, at a purchase price in cash in an amount equal to 100% of the
principal amount thereof, plus accrued and unpaid interest and Special Interest,
if any, thereon to the date of purchase, in accordance with the procedures set
forth in Article 3 of this Indenture and the agreements governing such pari
passu Indebtedness. To the extent that any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use such Excess Proceeds
for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and pari passu Indebtedness tendered into such Asset
Sale Offer surrendered by Holders thereof exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes and pari passu Indebtedness to be purchased
on a pro rata basis. Upon completion of such Asset Sale Offer, the amount of
Excess Proceeds shall be reset at zero for purposes of the first sentence of
this paragraph.

          The amount of (x) any liabilities (as shown on the Company's (or such
Restricted Subsidiary's, as the case may be) most recent balance sheet) of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any guarantee
thereof) that are assumed by the transferee of any such assets pursuant to an
agreement that releases the Company or any Restricted Subsidiary from all
liability in respect thereof, (y) Indebtedness of any Restricted Subsidiary that
is no longer a Restricted Subsidiary as a result of such Asset Sale, to the
extent that the Company and each other Restricted Subsidiary are released from
any guarantee of payment of the principal amount of such Indebtedness in
connection with such Asset Sale and (z) any securities, notes or other
obligations received by the Company (or such Restricted Subsidiary, as the case
may be) from such transferee that are contemporaneously (subject to ordinary
settlement periods) converted by the Company (or such Restricted Subsidiary, as
the case may be) into cash and/or Cash Equivalents (to the extent of the cash
and/or Cash Equivalents received), will be deemed to be cash and/or Cash
Equivalents for purposes of this provision.

Section 4.11.  Transactions with Affiliates.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise

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 of the foregoing, an "Affiliate Transaction"), unless
(i) such Affiliate Transaction is on terms that are not materially 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 an unrelated Person and (ii) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $25.0 million, the Company delivers to the
Trustee a resolution of the Board of Directors set forth in an Officers'
Certificate certifying that such Affiliate Transaction complies with clause (i)
above and that such Affiliate Transaction is approved by a majority of the
disinterested members of the Board of Directors and an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view is obtained from an accounting, appraisal or investment banking firm of
national standing. Notwithstanding the foregoing, the following items shall not
be deemed to be Affiliate Transactions: (i) (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 

                                       51

securities, to employees, officers or directors in the ordinary course of
business, (c) any transaction with an officer or director in the ordinary course
of business not involving more than $250,000 in any one case, or (d) Management

including any amendments thereto (provided that the terms of such amendments are
not materially less favorable to the Company or the relevant Restricted
Subsidiary than the terms of such agreement prior to such amendment), (vi)
transactions with respect to capacity or dark fiber between the Company or any
Restricted Subsidiary and any Unrestricted Subsidiary or other Affiliate and
joint sales and marketing pursuant to an agreement or agreements between the
Company or any Restricted Subsidiary and any Unrestricted Subsidiary or other
Affiliate (provided that in the case of this clause (vi), such agreements are on
terms that are no less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained at the time of such
transaction in an arm's-length transaction with an unrelated third party or, in
the case of a transaction with an Unrestricted Subsidiary, are either (x)
entered into in connection with a transaction involving the selection by a
customer of cable system capacity entered into in the ordinary course of
business or (y) involve the provision by the Company or a Restricted Subsidiary
to an Unrestricted Subsidiary of sales and marketing services, operations,
administration and maintenance services or development services for which the
Company or such Restricted Subsidiary receives a fair rate of return (as
determined by the Board of Directors and set forth in an Officers' Certificate
delivered to the Trustee) above its expenses of providing such services; (vii)
any transaction entered into in the ordinary course of business between the
Company or any Restricted Subsidiary and any Unrestricted Subsidiary or any
Affiliate (provided that in the case of this clause (vii), such agreements are
on terms that are no less favorable to the Company or the relevant Restricted
Subsidiary than those that could have been obtained at the time of such
transaction in an arm's-length transaction with an unrelated third party) and
(viii) Restricted Payments that are permitted by Section 4.07 hereof.

Section 4.12.  Liens.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind securing Indebtedness which is pari passu
with or subordinated to the Notes (other than Permitted Liens) upon any of their
property or assets, now owned or hereafter acquired, unless all payments due
under this Indenture and the Notes are secured on an equal and ratable basis
with (or prior to, in the case of Indebtedness which is subordinated to the
Notes) the obligations so secured until such time as such obligations are no
longer secured by a Lien.

Section 4.13.  Business Activities.

          The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than a Permitted Business.

directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any Holder of any Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Notes unless such consideration is offered to be paid
or is paid to all Holders of the Notes that consent, waive or agree to amend
such terms or provisions of this Indenture or the Notes in the time frame set
forth in the solicitation documents relating to such consent, waiver or
agreement.

Section 4.15.  Offer to Repurchase Upon Change of Control.

          (a) Upon the occurrence of a Change of Control, each Holder of Notes
shall have the right to require the Company to purchase all or any part (equal
to $1,000 or an integral multiple thereof) of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer") at a purchase price in
cash (the "Change of Control Payment") equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Special Interest, if any,
thereon to the date of purchase (subject to the right of Holders of record on
the relevant record date to receive interest due on the relevant interest
payment date); provided, however, that the Company shall not be obligated to
repurchase Notes pursuant to this covenant in the event that it has exercised
its rights to redeem all of the Notes as described in Section 3.07 hereof.
Within 30 days following any Change of Control, the Company shall mail a notice
to each Holder describing the transaction or transactions that constitute the
Change of Control and offering to purchase Notes on the date specified in such
notice, which date shall be no earlier than 30 and no later than 60 days from
the date such notice is mailed (the "Change of Control Payment Date"), in
accordance with the procedures required by Section 3.07 hereof and described in
such notice.

          The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations to the extent such
laws and regulations are applicable in connection with the purchase of Notes as
a result of a Change of Control.  To the extent that the provisions of any
securities laws or regulations conflict with any of the provisions of this
Section 4.15, the Company shall comply with the applicable securities laws and
regulations and will be deemed not to have breached its obligations under this
Section 4.15 by virtue thereof.

          (b) On the Change of Control Payment Date, the Company shall, 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 Notes so accepted together with an Officer's Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company.  The Paying Agent shall promptly mail or deliver to each Holder of
Notes so tendered the Change of Control Payment for such Notes, and the Trustee
shall promptly authenticate and mail or deliver (or cause to be transferred by
book entry) to each Holder a new Note equal in principal amount to any
unpurchased portion of Notes surrendered, if any; provided that each such new
Note will be in a principal amount of $1,000 or an integral multiple thereof.
Prior to complying with the provisions of this Section 4.15, but in any event
within 90 days following a Change of Control the Company will either repay all
outstanding Senior Debt or obtain the requisite consents, if any under all
agreements governing outstanding Senior Debt to permit the repurchase of Notes
required by this Section 4.15.  The Company will publicly announce the result of
the Change of Control Offer on or as soon as practicable after the Change of
Control Payment Date.

          (c) Notwithstanding anything in the contrary to this Section 4.15, the
Company shall not be required to make a Change of Control Offer upon the
occurrence of 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 Section 3.07 hereof 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.

          To the extent that the provisions of any securities laws or
regulations conflict with the Asset Sale provisions of this Indenture, the
Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the Asset Sale
provisions of this Indenture.

Section 4.16.  Money for Payments to Be Held In Trust.

          If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal, premium, interest or Special
Interest, if any, with respect to the Notes, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal,
premium, interest or Special Interest, if any, so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents for the
Notes, it will, on or before each due date of the principal, premium, interest
or Special Interest, if any, with respect to the Notes, deposit with a Paying
Agent a sum in same day funds (or New York Clearing House funds if such deposit
is made prior to the date on which such deposit is required to be made)
sufficient to pay the principal, premium, interest or Special Interest, if any,
so becoming due (or at the option of the Company, payment of interest may be
mailed by check to the Holders of the Notes at their respective addresses set
forth in the register of Holders of Notes; provided that all payments with
respect to Notes represented by one or more permanent global Notes will be paid
by wire transfer of immediately available funds to the account of the Depository
Trust Company or any successor thereto) such sum to be held in trust for the
benefit of the Persons entitled to such principal, premium, interest or Special
Interest, if any, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of such action or any failure so to act.

          The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

     (a) hold all sums held by it for the payment of the principal of, premium,
if any, or interest on Notes in trust for the benefit of the Persons entitled
thereto until such sums shall be paid to such Persons or otherwise disposed of
as herein provided;

     (b) give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any payment of principal, premium,
interest or Special Interest, if any;

     (c) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

                                       54
<PAGE>
 
     (d) acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture relating to the duties, rights and obligations of
such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal, premium, interest or
Special Interest, if any, with respect to a Note and remaining unclaimed for two
years after such principal, premium, if any, or interest has become due and
payable shall be paid to the Company at the request of the Company or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Note shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, shall at
the expense of the Company cause notice to be promptly sent to each Holder that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such notification any unclaimed
balance of such money then remaining will be repaid to the Company.

Section 4.17.  No Senior Subordinated Debt

          The Company shall not, directly or indirectly, incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is

     (c) orders the liquidation of the Company or any of its Restricted
  Subsidiaries;

     and the order or decree remains unstayed and in effect for 60 consecutive
days.

Section 6.02.  Acceleration.

          If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately.   Notwithstanding the
foregoing, if an Event of Default specified in clause (vii) or (viii) of Section
6.01 hereof occurs with respect to the Company, any of its Restricted
Subsidiaries that constitutes a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary, all outstanding Notes shall be due and payable immediately without
further action or notice.  The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may on
behalf of all of the Holders rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal, interest or premium that has
become due solely because of the acceleration) have been cured or waived.

          If an Event of Default occurs by reason of any willful action (or
inaction) taken (or not taken) by or on behalf of the Company with the intention
of avoiding payment of the premium that the 

                                       57
<PAGE>
 
Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Notes to the
contrary notwithstanding. If an Event of Default occurs prior to December 1,
2003 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, upon acceleration of the
Notes, an additional premium shall also become and be immediately due and
payable in an amount, for each of the years beginning on December 1 of the years
set forth below, as set forth below (expressed as a percentage of the aggregate
principal amount to the date of payment that would otherwise be due but for the
provisions of this sentence):

          YEAR                                 PERCENTAGE
          ----                                 ----------
              
          1998................................ 114.000%
          1999................................ 112.250%
          2000................................ 110.500%
          2001................................ 108.750%
          2002................................ 107.000%

Section 6.03.  Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and interest and Special Interest, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  All remedies
are cumulative to the extent permitted by law.

Section 6.04.  Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Special Interest, if any, or interest
on, the Notes (including in connection with an offer to purchase).  Upon any
such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05.  Control by Majority.

          Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

                                       58

Section 6.06.  Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

          (a) the Holder of a Note gives to the Trustee written notice of a
continuing Event of Default;

          (b) the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy;

          (c) such Holder of a Note or Holders of Notes offer and, if requested,
provide to the Trustee indemnity satisfactory to the Trustee against any loss,
liability or expense;

          (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

          (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

          A Holder of a Note may not use this Indenture to prejudice the rights
of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07.  Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal, premium and Special
Interest, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08.  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(i) or (ii) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium and Special Interest, if any, and interest
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09.  Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to participate as a member, voting or otherwise, of
any official committee of creditors appointed in such matter and shall be
entitled and empowered to collect, receive and distribute any money or other
property payable or 

                                       59
<PAGE>
 
deliverable on any such claims and any custodian in any such judicial proceeding
is hereby authorized by each Holder to make such payments to the Trustee, and in
the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

Section 6.10.  Priorities.

          If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

          First:  to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

          Second:  to Holders of Notes for amounts due and unpaid on the Notes
for principal, premium and Special Interest, if any, and interest, ratably,
without preference or priority of any kind, according to the amounts due and
payable on the Notes for principal, premium and Special Interest, if any, and
interest, respectively; and

          Third:  to the Company or to such party as a court of competent
jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

Section 6.11.  Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of
a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.


                                   ARTICLE 7.

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and

  rely, as to the truth of the statements and the correctness of the opinions
  expressed therein, upon certificates or opinions furnished to the Trustee and
  conforming to the requirements of this Indenture.  However, the Trustee shall
  examine the certificates and opinions to determine whether or not they conform
  to the requirements of this Indenture (but need not confirm or investigate the
  accuracy of mathematical calculations or other facts stated therein or
  otherwise verify the contents thereof).

     (c) The Trustee may not be relieved from liabilities for its own negligent
action, its own negligent failure to act, or its own willful misconduct, except

risk its own funds or incur any liability.  The Trustee shall be under no

Officers' Certificate or an Opinion of Counsel or both.  The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel.  The Trustee may consult with
counsel of its selection and the advice of such counsel or any Opinion of

request, direction or notice from the Company shall be sufficient if signed by
an Officer of the Company.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee.  However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee or resign.  Any Agent may do the same with
like rights and duties.  The Trustee is also subject to Sections 7.10 and 7.11
hereof.

paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05.  Notice of Defaults.

     (a) The Trustee shall not be deemed to have notice of any Default or Event

notice references the Notes and this Indenture.

                                       62
<PAGE>
 
     (b) If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs.  Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest on any Note, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Notes.

Section 7.06.  Reports by Trustee to Holders of the Notes.

          Within 60 days after each December 15 beginning with the December 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee shall mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA (S) 313(a) (but if no
event described in TIA (S) 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted).  The Trustee also
shall comply with TIA (S) 313(b)(2).  The Trustee shall also transmit by mail
all reports as required by TIA (S) 313(c).

          A copy of each report at the time of its mailing to the Holders of
Notes shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Notes are listed in accordance with TIA (S) 313(d).  The
Company shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

Section 7.07.  Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the
parties shall agree from time to time.  The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust.  The
Company shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by it in addition to the
compensation for its services.  Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

          The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith.  The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity.  Failure by the Trustee to so notify the
Company shall not relieve the Company of its obligations hereunder.  The Company
shall defend the claim and the Trustee shall cooperate in the defense.  The
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel.  The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld or
delayed.

          The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

                                       63
<PAGE>
 
          To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Notes.  Such Lien shall survive the satisfaction and
discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(viii) or (ix) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA (S) 313(b)(2) to
the extent applicable.

Section 7.08.  Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

          The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company.  The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing.  The Company may
remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.10 hereof;

     (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

     (c) a custodian or public officer takes charge of the Trustee or its

office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.  Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Notes of at least 10% in principal amount of the then outstanding
Notes may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

          If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10 hereof, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Thereupon, the
resignation or removal of the retiring Trustee shall become 

                                       64
<PAGE>
 
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Holders of the Notes. The retiring Trustee shall
promptly transfer all property held by it as Trustee to the successor Trustee,
provided all sums owing to the Trustee hereunder have been paid and subject to
the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Company's obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09.  Successor Trustee by Merger, etc.

          If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

Section 7.10.  Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S) 310(a)(1), (2) and (5).  The Trustee is subject to TIA
(S) 310(b).

Section 7.11.  Preferential Collection of Claims Against Company.

          The Trustee is subject to TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated therein.

the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and

                                       65

respect to the outstanding Notes on and after the date the conditions set forth

Notes shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes).  For this purpose, Covenant Defeasance means that, with respect to
the outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby.  In addition, upon the Company's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(iii) through 6.01(vi) hereof shall not constitute Events of Default.

Section 8.04.  Conditions to Legal or Covenant Defeasance.

          The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

          In order to exercise either Legal Defeasance or Covenant Defeasance:

     (a) the Company must irrevocably deposit, or cause to be deposited, 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, premium, and Special
Interest, if any, and interest on the outstanding Notes on the stated maturity
thereof 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;

                                       66
<PAGE>
 
     (b) in the case of Legal Defeasance, the Company must deliver to the
Trustee an Opinion of Counsel in the United States reasonably acceptable to the
Trustee confirming that the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or since the Issue Date,
there has been a change in the applicable federal income tax law, in either case
to the effect that, and based thereon such Opinion of Counsel shall confirm
that, the Holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance, and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had
not occurred;

     (c) in the case of Covenant Defeasance, the Company must deliver to the
Trustee an Opinion of Counsel in the United States reasonably acceptable to the
Trustee confirming that the Holders of the outstanding Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance, and such Holders will be subject to federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such Covenant Defeasance had not occurred;

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

     (e) 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 this 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;

     (f) the Company must deliver to the Trustee an opinion of counsel in the
United States reasonably acceptable to the Trustee 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 and remedies generally;

     (g) 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 the Notes over other creditors of the Company, or with
the intent of defeating, hindering, delaying or defrauding creditors of the
Company or others;

     (h) the Company must deliver to the Trustee an Opinion of Counsel in
Bermuda reasonably acceptable to the Trustee to the effect that the Holders of
the outstanding Notes will not be adversely affected under Bermuda law; and

     (i) the Company must deliver to the Trustee an Officers' Certificate and an
Opinion of Counsel in the United States reasonably acceptable to the Trustee,
each stating that all conditions precedent provided for or relating to Legal
Defeasance or Covenant Defeasance, as applicable, have been complied with.

Section 8.05.  Deposited Money and Government Securities to be Held in Trust;
               Other Miscellaneous Provisions.

                                       67
<PAGE>
 
          Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 hereof or the principal
and interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

          Anything in this Article 8 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

Section 8.06.  Repayment to Company.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, interest
or Special Interest, if any, on any Note and remaining unclaimed for two years
after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Company on its request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Note shall
thereafter, as a secured creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

Section 8.07.  Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest on any Note following the
reinstatement of its

                                       68
<PAGE>
 
obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money held by the Trustee or Paying
Agent.

Section 8.08.  Survival.

          The Trustee's rights under this Article 8 shall survive termination of
this Indenture.

                                  ARTICLE 9.
                       AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01.  Without Consent of Holders of Notes.

          Notwithstanding Section 9.02 hereof, the Company and the Trustee may
amend or supplement this Indenture or the Notes without the consent of any
Holder of a Note:

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

     (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes or to alter the provisions of Article 2 hereof (including the
related definitions) in a manner that does not materially adversely affect any
Holder;

     (c) to provide for the assumption of the Company's obligations to the
Holders of the Notes by a successor to the Company pursuant to Article 5 hereof;

     (d) to make any change that would provide any additional rights or benefits
to the Holders of the Notes or that does not adversely affect the legal rights
hereunder of any Holder of the Note; or

     (e) to comply with requirements of the SEC in order to effect or maintain
the qualification of this Indenture under the TIA.

          Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company in the execution of any
amended or supplemental indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

Section 9.02.  With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Section 3.11, 4.10 and
4.15 hereof) and the Notes with the consent of the Holders of at least a
majority in principal amount of the then outstanding Notes then outstanding
voting as a single class (including consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Notes), and, subject to
Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other
than a Default or Event of Default in the payment of the principal of, premium,
if any, or interest on the Notes, except a payment default resulting from an
acceleration that has been rescinded) or compliance with any provision of this
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes voting as a single

                                       69
<PAGE>
 
class (including consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes).

          Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Company in the execution of such amended or supplemental indenture
unless such amended or supplemental indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental indenture.

          It shall not be necessary for the consent of the Holders of Notes
under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver.  Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amended or
supplemental indenture or waiver.  Subject to Sections 6.04 and 6.07 hereof, the
Holders of a majority in aggregate principal amount of the Notes then
outstanding voting as a single class may waive compliance in a particular
instance by the Company with any provision of this Indenture or the Notes.
However, without the consent of each Holder affected, an amendment or waiver
under this Section 9.02 may not (with respect to any Notes held by a non-
consenting Holder):

     (a) reduce the principal amount of Notes whose Holders must consent to an
amendment, supplement or waiver;

     (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive any of the provisions with respect to the redemption of the
Notes, other than redemption provisions relating to Sections 3.11, 4.10 or 4.15
hereof;

     (c) reduce the rate of, or change the time for, payment of interest,
including default interest, on any Note;

     (d) waive a Default or Event of Default in the payment of principal of, or
premium or Special Interest, if any, or interest on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in
aggregate principal amount of the then outstanding Notes and a waiver of the
payment default that resulted from such acceleration);

     (e) make any Note payable in money other than that stated in the Notes;

     (f) make any change in the provisions of this Indenture relating to waivers
of past Defaults or the rights of Holders of Notes to receive payments of
principal of or premium, if any, or interest or Special Interest, if any, on the
Notes;

                                       70
<PAGE>
 
     (g) waive a redemption payment with respect to any Note, other than a
payment required by Section 3.11, 4.10 or 4.15 hereof;

     (h) make any change in the foregoing amendment and waiver provisions.

          In addition, any amendment to Article 10 hereof shall require the
consent of the Holders of at least 75% in aggregate principal amount of the
Notes then outstanding if such amendment would adversely affect the rights of
the Holders of the Notes.

Section 9.03.  Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental indenture that complies with the TIA as
then in effect.

Section 9.04.  Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note.  However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective.  An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

Section 9.05.  Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated.  The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06.  Trustee to Sign Amendments, etc.

          The Trustee shall sign any amended or supplemental indenture
authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental indenture until the Board
of Directors approves it.  In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon an Officer's Certificate and an Opinion
of Counsel stating that the execution of such amended or supplemental indenture
is authorized or permitted by this Indenture and that such amendment is the
legal, valid and binding obligation of the Company, enforceable against them in
accordance with their terms, subject to customary exceptions, and complies with
the provisions hereof (including Section 9.03).

                                  ARTICLE 10.
                                 SUBORDINATION


                                       71
<PAGE>
 

Section 10.01.  Agreement to Subordinate.

          The Company agrees, and each Holder by accepting a Note agrees, that
the Indebtedness evidenced by the Note is subordinated in right of payment, to
the extent and in the manner provided in this Article, to the prior payment in
full of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt.

Section 10.02.  Certain Definitions.

          "Designated Senior Debt" means (i) Indebtedness represented by the
Senior Notes, (ii) Indebtedness pursuant to paragraph (n) of the second full
paragraph of Section 4.09 hereof and (iii) any Senior Debt permitted to be
incurred under the Indenture the principal amount of which is $25.0 million or
more and that has been designated by the Company as "Designated Senior Debt."

          "Permitted Junior Securities" means Equity Interests in the Company or
debt securities that are subordinated to all Senior Debt (and any debt
securities issued in exchange for Senior Debt) to substantially the same extent
as, or to a greater extent than, the Notes are subordinated to Senior Debt
pursuant to this Indenture.

          "Representative" means the indenture trustee or other trustee, agent
or representative for any Senior Debt.

          "Senior Debt" means (i) all Indebtedness represented by the Senior
Notes, (ii) any other Indebtedness permitted to be incurred by the Company under
the terms of this Indenture, unless the instrument under which such Indebtedness
is incurred expressly provides that it is on a parity with or subordinated in
right of payment to the Notes and (iii) all Obligations with respect to the
foregoing.  Notwithstanding anything to the contrary in the foregoing, Senior
Debt will not include (w) any liability for federal, state, local or other taxes
owed or owing by the company, (x) any Indebtedness of the Company to any of its
Subsidiaries or other Affiliates, (y) any trade payables or (z) any Indebtedness
that is incurred in violation of the Senior Notes Indenture.

          A distribution may consist of cash, securities or other property, by
set off or otherwise.

Section 10.03.  Liquidation; Dissolution; Bankruptcy.

          Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities:

          (A)  (1)  holders of Senior Debt shall be entitled to receive payment
       in full of all Obligations due in respect of such Senior Debt (including
       interest after the commencement of any such proceeding at the rate
       specified in the applicable Senior Debt) before Holders shall be entitled
       to receive any payment with respect to the Notes (except that Holders may
       receive and retain (i) Permitted Junior Securities and (ii) payments and
       other distributions made from any defeasance trust created pursuant to
       Section 8.01 hereof); and

                                       72
<PAGE>
 
          (B)  (2)  until all Obligations with respect to Senior Debt (as
       provided in subsection (1) above) are paid in full, in cash any
       distribution to which Holders would be entitled but for this Article
       shall be made to holders of Senior Debt (except that Holders, in cash may
       receive and retain (i) Permitted Junior Securities and (ii) payments and
       other distributions made from any defeasance trust created pursuant to
       Section 8.01 hereof), as their interests may appear.

Section 10.04.  Default on Designated Senior Debt.

          The Company may not make any payment or distribution to the Trustee or
any Holder in respect of Obligations with respect to the Notes and may not
acquire from the Trustee or any Holder for cash or property (other than (i)
Permitted Junior Securities and (ii) payments and other distributions made from
any defeasance trust created pursuant to Section 8.01 hereof):

     (i) a default in the payment of any principal of, premium if any, or
  interest or Designated Senior Debt occurs and is continuing beyond any
  applicable grace period in the agreement, indenture or other document
  governing such Designated Senior Debt; or

     (ii) a default, other than a payment default, on Designated Senior Debt
  occurs and is continuing that then permits holders of the Designated Senior
  Debt to accelerate its maturity and the Trustee receives a notice of the
  default (a "Payment Blockage Notice") from a Person who may give it pursuant
  to Section 10.12 hereof.  If the Trustee receives any such Payment Blockage
  Notice, no subsequent Payment Blockage Notice shall be effective for purposes
  of this Section unless and until (i) at least 360 days shall have elapsed
  since the effectiveness of the immediately prior Payment Blockage Notice and
  (ii) all scheduled payments of principal, premium and Special Interest, if
  any, and interest on the Notes that have come due have been paid in full in
  cash.   No nonpayment default that existed or was continuing on the date of
  delivery of any Payment Blockage Notice to the Trustee shall be, or be made,
  the basis for a subsequent Payment Blockage Notice unless such default shall
  have been waived for a period of not less than 90 days.

          The Company may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

          (C)  (1)  in the case of a payment default, the date upon which the
       default is cured or waived, or

          (D)  (2)  in the case of a default referred to in Section 10.04(ii)
       hereof, the easier of the date on which such default is cured or waived
       or 179 days after the date on which the applicable Payment Blockage
       Notice is received if the maturity of such Designated Senior Debt has not
       been accelerated,

if this Article otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

Section 10.05.  Acceleration of Notes.

          If payment of the Notes is accelerated because of an Event of Default,
the Company shall promptly notify holders of Senior Debt of the acceleration.

                                       73
<PAGE>
 
Section 10.06.  When Distribution Must Be Paid Over.

          In the event that the Trustee or any Holder receives any payment of
any Obligations with respect to the Notes at a time when the Trustee or such
Holder, as applicable, has actual knowledge that such payment is prohibited by
Section 10.04 hereof, such payment shall be held by the Trustee or such Holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to, the holders of Senior Debt as their interests may
appear or their Representative under the indenture or other agreement (if any)
pursuant to which Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of all Obligations with
respect to Senior Debt remaining unpaid to the extent necessary to pay such
Obligations in full in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 10, and no implied covenants or obligations with respect
to the holders of Senior Debt shall be read into this Indenture against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 10, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

Section 10.07.  Notice by Company.

          The Company shall promptly notify the Trustee and the Paying Agent of
any facts known to the Company that would cause a payment of any Obligations
with respect to the Notes to violate this Article, but failure to give such
notice shall not affect the subordination of the Notes to the Senior Debt as
provided in this Article.

Section 10.08.  Subrogation.

          After all Senior Debt is paid in full and until the Notes are paid in
full, Holders shall be subrogated (equally and ratably with all other
Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt
to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders have been applied to the payment
of Senior Debt.  A distribution made under this Article to holders of Senior
Debt that otherwise would have been made to Holders is not, as between the
Company and Holders, a payment by the Company on the Notes.

Section 10.09.  Relative Rights.

          This Article defines the relative rights of Holders and holders of
Senior Debt.  Nothing in this Indenture shall:

          (E)  (1)  impair, as between the Company and Holders, the obligation
       of the Company, which is absolute and unconditional, to pay principal of
       and interest and Special Interest, if any, on the Notes in accordance
       with their terms;

          (F)  (2)  affect the relative rights of Holders and creditors of the
       Company other than their rights in relation to holders of Senior Debt; or

                                       74
<PAGE>
 
          (G)  (3)  prevent the Trustee or any Holders from exercising its
       available remedies upon a Default or Event of Default, subject to the
       rights of holders and owners of Senior Debt to receive distributions and
       payments otherwise payable to Holders.

          If the Company fails because of this Article to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

Section 10.10.  Subordination May Not Be Impaired by Company.

          No right of any holder of Senior Debt to enforce the subordination of
the Indebtedness evidenced by the Notes shall be impaired by any act or failure
to act by the Company or any Holder or by the failure of the Company or any
Holder to comply with this Indenture.

Section 10.11.  Distribution or Notice to Representative.

          Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

          Upon any payment or distribution of assets of the Company referred to
in this Article 10, the Trustee and the Holders shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction or upon any
certificate of such Representative or of the liquidating trustee or agent or
other Person making any distribution to the Trustee or to the Holders for the
purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Debt and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 10.

Section 10.12.  Rights of Trustee and Paying Agent.

          Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Notes to violate this Article.  Only the Company or a
Representative may give the notice.  Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

          The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee.  Any Agent may
do the same with like rights.

Section 10.13.  Authorization to Effect Subordination.

          Each Holder of a Note by the Holder's acceptance thereof authorizes
and directs the Trustee on the Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as the Holder's attorney in fact for
any and all such purposes.  If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section
6.09 hereof at least 30 days before the 

                                       75

expiration of the time to file such claim, the Representatives are hereby
authorized to file an appropriate claim for and on behalf of the Holders of the
Securities.

Section 10.14.  Amendments.

          The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of all Senior Debt.

Section 11.01. Satisfaction and Discharge of Indenture.

          This Indenture shall be discharged and will cease to be of further
effect as to all Notes issued hereunder, when either

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

    (b)  (i)   all such Notes not theretofore delivered to such Trustee for
               cancellation have become due and payable by reason of the making
               of a notice of redemption or otherwise or will become due and
               payable within one year and the Company has irrevocably deposited
               or caused to be deposited with such Trustee as trust funds in
               trust an amount of money sufficient to pay and discharge the
               entire Indebtedness on such Notes not theretofore delivered to
               the Trustee for cancellation for principal, premium, accrued
               interest and Special Interest, if any, to the date of maturity or
               redemption;
              
         (ii)  no Default or Event of Default with respect to this Indenture or
               the Notes shall have occurred and be continuing on the date of
               such deposit or shall occur as a result of such deposit and such
               deposit will not result in a breach or violation of, or
               constitute a default under, any other instrument to which the
               Company is a party or by which the Company is bound;
              
         (iii) the Company has paid or caused to be paid all sums payable by
               it under this Indenture; and

         (iv)  the Company has delivered irrevocable instructions to the Trustee
               under this Indenture to apply the deposited money toward the
               payment of such Notes at maturity or the redemption date, as the
               case may be.

          In addition, the Company 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.

<PAGE>
 
          Subject to the provisions of the last paragraph of Section 4.19
hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof
shall be held in trust and applied by it, in accordance with the provisions of
the Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to Persons entitled thereto, of the principal (and premium, if any),
interest and Special Interest, if any, for whose payment such money has been
deposited with the Trustee.

          If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 11.01 hereof by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Notes shall
be revived and reinstated as though such deposit had occurred pursuant to
Section 11.01 hereof; provided that if the Company has made any payment of
principal of, premium, if any, or interest on any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or
Government Securities held by the Trustee or Paying Agent.

<PAGE>
 
          THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Section 12.09. Currency Indemnity.

          U.S. dollars are the sole currency of account and payment for all sums
payable by the Company under or in connection with the Notes, including damages.
Any account received or recovered in a currency other than dollars (whether as a
result of, or the enforcement of, a judgment or order of a court of any
jurisdiction, in the liquidation, dissolution or other winding-up of the affairs
of the Company or otherwise) by any Holder of a Note in respect of any sum
expressed to be due to it from the Company shall only constitute a discharge to
the Company to the extent of the dollar amount which the recipient is able to
purchase with the amount so received or recovered in that other currency on the
date of that receipt or recovery (or, if it is not practicable to make that
purchase on that date, on the first date on which it is practicable to do so).
If that dollar amount is less than the dollar amount expressed to be due to the
recipient under any Note, the Company shall indemnify it against any loss
sustained by it as a result. In any event, the Company shall indemnify the
recipient against the cost of making any such purchase. For the purposes of this
paragraph, it will be sufficient for the Holder of a Note to certify in a
satisfactory manner (indicating the sources of information used) that it would
have suffered a loss had an actual purchase of dollars been made with the amount
so received in that other currency on the date of receipt or recovery (or, if a
purchase of dollars on such date had not been practicable, on the first date on
which it would have been practicable, it being required that the need for a
change of date be certified in the manner mentioned above). These indemnities
constitute a separate and independent obligation from the Company's other
obligations, shall give rise to a separate and independent cause of action,
shall apply irrespective of any indulgence granted by any Holder of a Note and
shall constitute in full force and effect despite any other judgment, order,
claim or proof for a liquidated amount in respect of any sum due under any Note.

Section 12.10. Consent to Jurisdiction and Service.

          To the fullest extent permitted by applicable law, the Company hereby
irrevocably submits to the jurisdiction of any Federal or State court located in
the Borough of Manhattan in The City of New York, New York in any suit, action
or proceeding based on or arising out of or relating to this Agreement or any
Notes or Exchange Notes, and irrevocably agree that all claims in respect of
such suit or proceeding may be determined in any such court.  The Company
irrevocably waives, to the fullest extent permitted by law, any objection which
they may have to the laying of the venue of any such suit, action or proceeding
brought in such a court and any claim that any suit, action or proceeding
brought in such a court has been brought in an inconvenient forum.  The Company
agrees that final judgment in any such suit, action or proceeding brought in
such a court shall be conclusive and binding upon the Company and may be
enforced in the courts of Bermuda (or any other courts to the jurisdiction of
which the Company is subject) by a suit upon such judgment, provided that
                                                            --------     
service of process is effected upon the Company in the manner specified herein
or as otherwise permitted by law. The Company hereby irrevocably designates and
appoints CT Corporation System, 1633 Broadway - 23rd Floor, New York, New York
(the "Process Agent"), as the authorized agent of the Company upon whom process
may be served in any such suit or proceeding, it being understood that the
designation and appointment of the Process Agent as such authorized agent shall
become effective immediately without any further action on the part of the
Company. The Company hereby represents to each Initial Purchaser that it has
notified the Process Agent of such designation and appointment and that the
Process Agent has accepted the same in writing. The Company hereby irrevocably
authorizes and directs the Process Agent to accept such

                                       80
<PAGE>
 
service. The Company further agrees that service of process upon the Process
Agent and written notice of said service to the Company mailed by prepaid
registered first class mail or delivered to the Process Agent at its principal
office, shall be deemed in every respect effective service of process upon the
Company in any such suit or proceeding. Nothing herein shall affect the right of
any Initial Purchaser or any person controlling any Initial Purchaser to serve
process in any other matter permitted by law. The Company further agrees to take
any and all action, including the execution and filing of any and all such
documents and instruments as may be necessary to continue such designation and
appointment of the Process Agent in full force and effect so long as the Company
has any outstanding obligations under this Agreement, the Notes, the Exchange
Notes or this Indenture. To the extent that the Company has or hereafter may
acquire any immunity from jurisdiction of any court or from any legal process
(whether through service of note, attachment prior to judgment, attachment in
aid of execution, executor or otherwise) with respect to itself or its property,
the Company hereby irrevocably waives such immunity in respect of their
respective obligations under this Agreement, to the extent permitted by law.

Section 12.11. No Adverse Interpretation of Other Agreements.

          This Indenture may not be used to interpret any other indenture, loan
or debt agreement of the Company or its Subsidiaries or of any other Person.
Any such indenture, loan or debt agreement may not be used to interpret this
Indenture.

Section 12.12. Successors.

          All agreements of the Company in this Indenture and the Notes shall
bind its successors.  All agreements of the Trustee in this Indenture shall bind
its successors.

Section 12.13. Severability.

          In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 12.14. Counterpart Originals.

          The parties may sign any number of copies of this Indenture.  Each
signed copy shall be an original, but all of them together represent the same
agreement.

Articles and Sections of this Indenture have been inserted for convenience of

interest has been paid, from the date of issuance; provided that if there is no
existing Default or Event of Default relating to the payment of interest, and if
this Note is authenticated between a record date referred to on the face hereof
and the next succeeding Interest Payment Date, interest shall accrue from such
next succeeding Interest Payment Date; provided, further, that the first
Interest Payment Date shall be [ ]. The Company shall pay interest (including

extent lawful. Interest shall be computed on the basis of a 360-day year of
twelve 30-day months.

          2.  Method of Payment.  The Company shall pay interest on the Notes
(except defaulted interest) and Special Interest to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November
15 next preceding the Interest Payment Date, even if such Notes are canceled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes shall be payable as to principal, premium and Special Interest, if
any, and interest at the office or agency of the Company maintained for such
purpose within or outside of the City and State of New York, or, at the option

Indenture Act of 1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb) (the
"TIA"). The Notes are subject to all such terms, and Holders are referred to the
Indenture and the TIA for a statement of such terms. To the extent any provision
of this Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. The Notes are

date, with the net cash proceeds received from one or more Equity Offerings made

to the Indenture remain outstanding immediately after the occurrence of any such
redemption. The Company may make any such redemption upon not less than 30 nor
more than 60 days' notice (but in no event more than 90 days after the closing
of the related Equity Offering). Any such notice may be given prior to the
completion of the related Equity Offering and any such redemption may, at the
Company's discretion, be subject to the satisfaction of one or more conditions
precedent, including, but not limited to, the completion of the related Equity
Offering.

          (c) In addition, at any time prior to December 1, 2003, the Notes may
also be redeemed at the option of the Company, in whole but not in part, upon
the occurrence of a Change of Control, upon not less than 30 nor more than 60

          (d) Any redemption pursuant to this Section 5 shall be made pursuant
to the provisions of Sections 3.01 through 3.06 of the Indenture.

          6.  Optional Tax Redemption

          The Notes shall be subject to redemption at the option of the Company
or a successor corporation at any time, in whole but not in part, upon not less
than 30 nor more than 60 days' notice, at a redemption price equal to the
principal amount thereof, plus accrued and unpaid interest thereon to the
redemption date if, as a result of any change in or amendment to the laws or any
regulations or ruling promulgated thereunder of (x) Bermuda or any political
subdivision or governmental authority thereof or therein having the power to
tax, (y) any jurisdiction, other than the United States, from or through which
payment on the Notes is made by the Company or a successor corporation, or its
paying agent in its capacity as such or any political subdivision or
governmental authority thereof or therein having the power to tax or (z) any
other jurisdiction, other than the United States, in which the Company or a
successor corporation is organized, or any political subdivision or governmental
authority thereof or therein having the power to tax, or any change in the
official application or interpretation of such laws, regulations or rulings, or
any change in the official application or interpretation of, or any execution of
or amendment to, any treaty or treaties affecting taxation to which such
jurisdiction (or such political subdivision or taxing authority) is a party (a
"Change in Tax Law"), which becomes effective on or after the Issue Date, the
Company or a successor corporation is or would be required on the next
succeeding interest payment date to pay Additional Amounts with respect to the
Notes (as described under Section 7 hereof), and the payment of such Additional
Amounts cannot be avoided by the use of any reasonable measures available to the
Company or a successor corporation.

          In addition, the Notes shall be subject to redemption at the option of
the Company at any time, in whole but not in part, upon not less than 30 nor
more than 60 days' notice, at a redemption price equal to the principal amount

of such consolidation, amalgamation, merger, conveyance, transfer or lease and
as a consequence of a Change in Tax Law occurring after the date of such
consolidation, amalgamation, merger, conveyance, transfer or lease, to pay
Additional Amounts in respect of any tax, assessment or governmental charge
imposed on any Holder of Notes.

          7.  Payment of Additional Amounts.

          If any deduction or withholding for any present or future taxes,
assessments or other governmental charges of (x) Bermuda or any political
subdivision or governmental authority thereof or therein having power to tax,
(y) any jurisdiction, other than the United States, from or through which
payment on the Notes is made by the Company or a successor corporation, or its
paying agent in its capacity as such or any political subdivision or
governmental authority thereof or therein having the power to tax or (z) any
other jurisdiction, other than the United States, in which the Company or a
successor corporation is organized, or any political subdivision or governmental
authority thereof or therein having the power to tax shall at any time be
required by such jurisdiction (or any such political subdivision or taxing
authority) in respect of any amounts to be paid by the Company or a successor
corporation under the Notes, the Company or a successor corporation shall pay to
each Holder of Notes as additional interest, such additional amounts
("Additional Amounts") as may be necessary in order that the net amounts paid to
such Holder of such Notes who, with respect to any such tax, assessment or other
governmental charge, is not resident in, or a citizen of, such jurisdiction,
after such deduction or


                                     A-1-5
<PAGE>
 
withholding, shall be not less than the amount specified in such Notes to which
such Holder is entitled; provided, however, that the Company or a successor
corporation shall not be required to make any payment of Additional Amounts for
or on account of:

     (a) Any tax, assessment or other governmental charge that would not have
been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership, limited liability company or corporation) and the
taxing jurisdiction or any political subdivision or territory or possession
thereof or area subject to its jurisdiction, including, without limitation, such
Holder (or such fiduciary, settlor, beneficiary, member, shareholder 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 a
permanent establishment therein, (ii) the presentation of a 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, or (iii) the
presentation of a Note for payment in Bermuda or any political subdivision
thereof or therein, unless such Note could not have been presented for payment
elsewhere;

     (b) Any estate, inheritance, gift, sales, transfer, personal property or
similar tax, assessment or other governmental charge;

     (c) Any tax, assessment or other governmental charge that is payable
otherwise than by withholding from payment of principal of, premium, if any, or
any interest on the Notes;

     (d) 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 request of the Company addressed to the Holder (i) to
provide information, documents or other evidence concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make and
deliver any declaration or other similar claim or satisfy any information or
reporting requirements, which, in the case of (i) or (ii), 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; or

     (e) Any combination of items (a), (b), (c) and (d) above;

         nor shall Additional Amounts be paid with respect to any payment of the
principal of, or any premium or interest on, any Note to any Holder who is a
fiduciary or partnership or limited liability company or other than the sole
beneficial owner of such payment to the extent such payment would be required by
the laws of (x) Bermuda or any political subdivision or governmental authority
thereof or therein having the power to tax, (y) any jurisdiction, other than the
United States, from or through which payment on the Notes is made by the Company
or a successor corporation, or its paying agent in its capacity as such or any
political subdivision or governmental authority thereof or therein having the
power to tax or (z) any other jurisdiction, other than the United States, in
which the Company or a successor corporation is organized, or any political
subdivision or governmental authority thereof or therein having the power to tax
to be included in the income for tax purposes of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership, limited liability
company or beneficial owner who would not have been entitled to such Additional
Amounts had it been the Holder of such Note. 

                                     A-1-6
<PAGE>
 
          The Company shall provide the Trustee with the official acknowledgment
of the relevant taxing authority (or, if such acknowledgment is not available, a
certified copy thereof) evidencing the payment of the withholding taxes, if any,
by the Company. Copies of such documentation shall be made available to the
Holders of the Notes or the Paying Agent, as applicable, upon request therefor.

          All references herein and in the Indenture to principal of, premium,
if any, and interest on the Notes shall include any Additional Amounts payable
by the Company in respect of such principal, such premium, if any, and such
interest.

          8.  Mandatory Redemption.

          The Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

          9.  Repurchase at Option of Holder.

          (a) Upon the occurrence of a Change of Control, the Company shall make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof, plus accrued and
unpaid interest and Special Interest thereon, if any, to the date of repurchase
(the "Change of Control Payment"); provided, however, that the Company shall not
be obligated to repurchase Notes pursuant to this subparagraph in the event that
it has exercised its rights to redeem all of the Notes as described in Section
5(c) hereof.  Within 30 days following any Change of Control, the Company shall
mail a notice to each Holder setting forth the procedures governing the Change
of Control Offer as required by the Indenture.

          (b) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, consummate any Asset Sale unless, (i)
the Company (or such Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (as determined in good faith by the Board of Directors (including as to
the value of all noncash consideration) and set forth in an Officers'
Certificate delivered to the Trustee) of the assets or Equity Interests issued
or sold or otherwise disposed of and (ii) at least 75% of the consideration
therefor is in the form of cash and/or Cash Equivalents, and (iii) the Net
Proceeds received by the Company (or such Restricted Subsidiary, as the case may
be) from such Asset Sale are applied within 360 days following the receipt of
such Net Proceeds (a) first, to the extent the Company (or such Restricted
Subsidiary, as the case may be) elects, to the redemption or repurchase of
outstanding Senior Debt and (b) second, to the extent of the balance of such Net
Proceeds after application as described in (a) above and to the extent the
Company (or such Restricted Subsidiary, as the case may be) elects, to reinvest,
or enter into a legally binding agreement to reinvest, such Net Proceeds (or any
portion thereof) in assets that are used or useful in a Permitted Business. The
balance of such Net Proceeds, after the application of such Net Proceeds as
described in the immediately preceding clauses (a) and (b), shall constitute
"Excess Proceeds."

          (c) When the aggregate amount of Excess Proceeds equals or exceeds
$15.0 million (taking into account income earned on such Excess Proceeds), the
Company shall make an offer to all Holders of Notes and pari passu Indebtedness
(an "Asset Sale Offer") to purchase the maximum principal amount of Notes and
pari passu Indebtedness that may be purchased out of the Excess Proceeds, at a
purchase price in cash in an amount equal to 100% of the principal amount
thereof, plus accrued and unpaid interest and Special Interest, if any, thereon
to the date of purchase, in accordance with the

                                     A-1-7
<PAGE>
 
procedures set forth in Article 3 of the Indenture and the agreements governing
such pari passu Indebtedness. To the extent that 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 pari passu Indebtedness tendered into
such Asset Sale Offer surrendered by Holders thereof exceeds the amount of
Excess Proceeds, the Trustee shall select the Notes and pari passu Indebtedness
to be purchased on a pro rata basis. Upon completion of such Asset Sale Offer,
the amount of Excess Proceeds shall be reset at zero for purposes of the first
sentence of this paragraph.

          10.  Notice of Redemption.  Notice of redemption shall be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address.  Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed.  On and after the redemption date interest shall cease to accrue on
Notes or portions thereof called for redemption.

          11.  Denominations, Transfer, Exchange.  The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000.  The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture.  The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Company may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture.  The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part.  Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

          12.  Persons Deemed Owners.  The registered Holder of a Note may be
treated as its owner for all purposes under the Indenture.

          13.  Amendment, Supplement and Waiver.  Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes voting as a single class, and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes voting
as a single class.  Without the consent of any Holder of a Note, the Indenture
or the Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Company's obligations
to Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any
such Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.


          14.  Defaults and Remedies.

          (a) Events of Default under the Indenture include:  (i) the failure to
pay interest on, or Special Interest, if any, with respect to the Notes, when
the same becomes due and payable if such default continues for a period of 30
days (whether or not prohibited by Article 10 of the Indenture), (ii) the
failure to pay principal of any Notes when such principal becomes due and
payable, at maturity, upon redemption or otherwise (whether or not prohibited by
Article 10 of the Indenture); (iii) failure by the 


                                     A-1-8
<PAGE>
 
Company or any Restricted Subsidiary for 60 days to comply with Sections 4.07,
4.09, 4.10 or 4.15 of the Indenture; (iv) failure by the Company or any
Restricted Subsidiary to comply with any of its other agreements in the
Indenture or this Note; (v) 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 of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries) whether 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 the maturity of which has
been so accelerated, aggregates $25.0 million or more; (vi) failure by the
Company or any of its Restricted Subsidiaries to pay final judgments not subject
to appeal aggregating in excess of $25.0 million (net of applicable insurance
coverage which is acknowledged in writing by the insurer), which judgments are
not paid, discharged or stayed for a period of 60 days; and (vii) certain events
of bankruptcy or insolvency with respect to the Company or any of the Company's
Restricted Subsidiaries.

          (b) If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately.  Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Notes shall become due and payable
without further action or notice.  Holders may not enforce the Indenture or the
Notes except as provided in the Indenture.  Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or, premium, if any, or interest on the Notes) if it determines that
withholding notice is in their interest.  The Holders of a majority in principal
amount of the then outstanding Notes by notice to the Trustee may on behalf of
the Holders of all of the Notes waive any existing Default or Event of Default
and its consequences under the Indenture, except a continuing Default or Event
of Default in the payment of interest on, premium, if any, or principal of, the
Notes.  The Company shall deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Company, upon becoming aware of any
Default or Event of Default, deliver to the Trustee a statement specifying such
Default or Event of Default.

          15. Subordination. The Company agrees, and each Holder by accepting
this Note agrees, that the principal of and premium, interest and Special
Interest, if any, with respect to the Notes are subordinated in right of
payment, to the extent and in the manner provided in Article 10 of the
Indenture, to the prior payment in full in cash of all Senior Debt of the
Company (whether outstanding on the date hereof or hereafter created, incurred,
assumed or guaranteed), and that the subordination is for the benefit of the
holders of Senior Debt.

          16. No Recourse Against Others.  A director, officer, employee,
incorporator or shareholder, of the Company, as such, shall not have any
liability for any obligations of the under the Notes or the Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

          17. Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

          18. Abbreviations.  Customary abbreviations may be used in the name
of a Holder or an assignee, such as:  TEN COM (= tenants in common), TEN ENT (=
tenants by the entirety), JT 

                                     A-1-9
<PAGE>
 
TEN (= joint tenants with right of survivorship and not as tenants in common),
CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

          19.  Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes.  In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Notes shall have all the rights set forth
in the Registration Agreement.

          20.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders.  No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

succeeding Business Day (each an "Interest Payment Date").  Interest on the
Notes shall accrue from the most recent date to which interest has been paid or,
if no interest has been paid, from the date of issuance; provided that if there
is no existing Default or Event of Default relating to the payment of interest,

hereof and the next succeeding Interest Payment Date, interest shall accrue from
such next succeeding Interest Payment Date; provided, further, that the first

that is 1.0% per annum in excess of the rate then in effect; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Special Interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful.  Interest shall be computed on the basis of
a 360-day year of twelve 30-day months.

          Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Note shall in all other respects be entitled
to the same benefits as other Notes under the Indenture.

          2.  Method of Payment.  The Company shall pay interest on the Notes

The Notes shall be payable as to principal, premium and Special Interest, if
any, and interest at the office or agency of the Company maintained for such
purpose within or outside of the City and State of New York, or, at the option
of the Company, payment of interest and Special Interest may be made by check
mailed to the Holders at their addresses set forth in the register of Holders,
and provided that payment by wire transfer of immediately available funds shall
be required with respect to principal of and interest, premium and Special
Interest on, all Global Notes and all other Notes the Holders of which shall

debts.

such Holder of such Notes who, with respect to any such tax, assessment or other
governmental charge, is not resident in, or a citizen of, such jurisdiction,
after such deduction or withholding, shall be not less than the amount specified
in such Notes to which such Holder is entitled; provided, however, that the
Company or a successor corporation shall not be required to make any payment of
Additional Amounts for or on account of:

     (a) Any tax, assessment or other governmental charge that would not have
been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership, limited liability company or corporation) and the

payment thereof is duly provided for, whichever occurs later, or (iii) the
presentation of a Note for payment in Bermuda or any political subdivision
thereof or therein, unless such Note could not have been presented for payment
elsewhere;

     (b) Any estate, inheritance, gift, sales, transfer, personal property or
similar tax, assessment or other governmental charge;

     (c) Any tax, assessment or other governmental charge that is payable
otherwise than by withholding from payment of principal of, premium, if any, or
any interest on the Notes;

     (d) 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 request of the Company addressed to the Holder (i) to
provide information, documents or other evidence concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) 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 (i) or
(ii), 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; or

     (e) Any combination of items (a), (b), (c) and (d) above;

         nor shall Additional Amounts be paid with respect to any payment of
the principal of, or any premium or interest on, any Note to any Holder who is a
fiduciary or partnership or limited liability company or other than the sole
beneficial owner of such payment to the extent such payment would be required by
the laws of (x) Bermuda or any political subdivision or governmental authority
thereof or


                                     A-2-7

therein having the power to tax, (y) any jurisdiction, other than the United
States, from or through which payment on the Notes is made by the Company or a
successor corporation, or its paying agent in its capacity as such or any
political subdivision or governmental authority thereof or therein having the
power to tax or (z) any other jurisdiction, other than the United States, in
which the Company or a successor corporation is organized, or any political
subdivision or governmental authority thereof or therein having the power to tax
to be included in the income for tax purposes of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership, limited liability
company or beneficial owner who would not have been entitled to such Additional
Amounts had it been the Holder of such Note.

          The Company shall provide the Trustee with the official acknowledgment
of the relevant taxing authority (or, if such acknowledgment is not available, a
certified copy thereof) evidencing the payment of the withholding taxes, if any,
by the Company. Copies of such documentation shall be made available to the
Holders of the Notes or the Paying Agent, as applicable, upon request therefor.


          All references herein and in the Indenture to principal of, premium,
if any, and interest on the Notes shall include any Additional Amounts payable
by the Company in respect of such principal, such premium, if any, and such
interest.

          8.  Mandatory Redemption.

          The Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

          9.  Repurchase at Option of Holder.

          (a) Upon the occurrence of a Change of Control, the Company shall make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof, plus accrued and
unpaid interest and Special Interest thereon, if any, to the date of repurchase
(the "Change of Control Payment"); provided, however, that the Company shall not
be obligated to repurchase Notes pursuant to this subparagraph in the event that
it has exercised its rights to redeem all of the Notes as described in Section
5(c) hereof.  Within 30 days following any Change of Control, the Company shall
mail a notice to each Holder setting forth the procedures governing the Change
of Control Offer as required by the Indenture.

          (b) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, consummate any Asset Sale unless, (i)
the Company (or such Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (as determined in good faith by the Board of Directors (including as to
the value of all noncash consideration) and set forth in an Officer's
Certificate delivered to the Trustee) of the assets or Equity Interests issued
or sold or otherwise disposed of and (ii) at least 75% of the consideration
therefor is in the form of cash and/or Cash Equivalents, and (iii) the Net
Proceeds received by the Company (or such Restricted Subsidiary, as the case may
be) from such Asset Sale are applied within 360 days following the receipt of
such Net Proceeds (a) first, to the extent the Company (or such Restricted
Subsidiary, as the case may be) elects, to the redemption or repurchase of
outstanding Senior Debt and (b) second, to the extent of the balance of such Net
Proceeds after application as described in (a) above and to the extent the
Company (or such Restricted Subsidiary, as the case may be) elects, to reinvest,
or enter into a legally binding agreement to reinvest, such Net Proceeds (or any
portion thereof) in assets that are used or useful in a Permitted Business. The
balance of such Net Proceeds, after the application of such Net Proceeds as
described in the immediately preceding clauses (a) and (b), shall constitute
"Excess Proceeds."

          (c) When the aggregate amount of Excess Proceeds equals or exceeds
$15.0 million 


                                     A-2-8
<PAGE>
 
(taking into account income earned on such Excess Proceeds), the Company shall
make an offer to all Holders of Notes and pari passu Indebtedness (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and pari passu
Indebtedness that may be purchased out of the Excess Proceeds, at a purchase
price in cash in an amount equal to 100% of the principal amount thereof, plus
accrued and unpaid interest and Special Interest, if any, thereon to the date of
purchase, in accordance with the procedures set forth in Article 3 of the
Indenture and the agreements governing such pari passu Indebtedness. To the
extent that 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 pari
passu Indebtedness tendered into such Asset Sale Offer surrendered by Holders
thereof exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes and pari passu Indebtedness to be purchased on a pro rata basis. Upon
completion of such Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero for purposes of the first sentence of this paragraph.

          10.  Notice of Redemption.  Notice of redemption shall be mailed at
least 30 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address.  Notes in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed.  On and after the redemption date interest shall cease to accrue on
Notes or portions thereof called for redemption.

          11.  Denominations, Transfer, Exchange.  The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000.  The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture.  The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Company may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture.  The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part.  Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.  This Regulation S Temporary
Global Note is exchangeable in whole or in part for one or more Global Notes
only (i) on or after the termination of the 40-day restricted period (as defined
in Regulation S) and (ii) upon presentation of certificates (accompanied by an
Opinion of Counsel, if applicable) required by Article 2 of the Indenture.  Upon
exchange of this Regulation S Temporary Global Note for one or more Global
Notes, the Trustee shall cancel this Regulation S Temporary Global Note.

          12.  Persons Deemed Owners.  The registered Holder of a Note may be
treated as its owner for all purposes under the Indenture.

          13.  Amendment, Supplement and Waiver.  Subject to certain exceptions,
the Indenture or the Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the then outstanding
Notes voting as a single class, and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes voting
as a single class. Without the consent of any Holder of a Note, the Indenture or
the Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Company's obligations
to Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights

                                     A-2-9
<PAGE>
 
under the Indenture of any such Holder, to comply with the requirements
of the SEC in order to effect or maintain the qualification of the Indenture
under the TIA.

          14.  Defaults and Remedies.

          (a)  Events of Default under the Indenture include: (i) the failure to
pay interest on or Special Interest, if any, with respect to the Notes, when the
same becomes due and payable if such default continues for a period of 30 days
(whether or not prohibited by Article 10 of the Indenture), (ii) the failure to
pay principal of any Notes when such principal becomes due and payable, at
maturity, upon redemption or otherwise (whether or not prohibited by Article 10
of the Indenture); (iii) failure by the Company or any Restricted Subsidiary for
60 days to comply with Sections 4.07, 4.09, 4.10 or 4.15 of the Indenture; (iv)
failure by the Company or any Restricted Subsidiary to comply with any of its
other agreements in the Indenture or this Note; (v) 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
of its Restricted Subsidiaries (or the payment of which is guaranteed by the
Company or any of its Restricted Subsidiaries) whether 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,
the maturity of which has been so accelerated, aggregates $25.0 million or more;
(vi) failure by the Company or any of its Restricted Subsidiaries to pay final
judgments not subject to appeal aggregating in excess of $25.0 million (net of
applicable insurance coverage which is acknowledged in writing by the insurer),
which judgments are not paid, discharged or stayed for a period of 60 days; and
(vii) certain events of bankruptcy or insolvency with respect to the Company or
any of the Company's Restricted Subsidiaries.

          (b)  If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable immediately.  Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Notes shall become due and payable
without further action or notice.  Holders may not enforce the Indenture or the
Notes except as provided in the Indenture.  Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal of, premium, if any, or interest on the Notes) if it determines that
withholding notice is in their interest.  The Holders of a majority in principal
amount of the then outstanding Notes by notice to the Trustee may on behalf of
the Holders of all of the Notes waive any existing Default or Event of Default
and its consequences under the Indenture, except a continuing Default or Event
of Default in the payment of interest on, premium, if any, or principal of, the
Notes.  The Company shall deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Company, upon becoming aware of any
Default or Event of Default, deliver to the Trustee a statement specifying such
Default or Event of Default.

          15.  Subordination. The Company agrees, and each Holder by accepting
this Note agrees, that the principal of and premium, interest and Special
Interest, if any, with respect to the Notes are subordinated in right of
payment, to the extent and in the manner provided in Article 10 of the
Indenture, to the prior payment in full in cash of all Senior Debt of the
Company (whether outstanding on the date hereof or hereafter created, incurred,
assumed or guaranteed), and that the subordination is for the benefit of the
holders of Senior Debt.

<PAGE>
 
          16.  Trustee Dealings with Company.  The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

          17.  No Recourse Against Others.  A director, officer, employee,
incorporator or shareholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation.  Each Holder by accepting a Note waives and releases all such
liability.  The waiver and release are part of the consideration for the
issuance of the Notes.

          18.  Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

          19.  Abbreviations.  Customary abbreviations may be used in the name
of a Holder or an assignee, such as:  TEN COM (= tenants in common), TEN ENT (=
tenants by the entirety), JT TEN (= joint tenants with right of survivorship and
not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to
Minors Act).

          20.  Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes.  In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Notes shall have all the rights set forth
in the Registration Agreement.

          21.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders.  No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

SECTION 2.  HOLDERS

     A Person is deemed to be a holder of Transfer Restricted Securities (each,
a "Holder") whenever such Person owns Transfer Restricted Securities.
   ------                                                            

SECTION 3.  REGISTERED EXCHANGE OFFER

     (a)  Unless the Exchange Offer shall not be permitted by applicable federal
law or Commission policy (after the procedures set forth in Section 6(a)(i)
below have been complied with), the Company shall (i) cause the Exchange Offer
Registration Statement to be filed with the Commission as soon as practicable
after the Closing Date (the "Exchange Offer Filing Date"), but in no event later
                             --------------------------                         
than 90 days after the Closing Date (such 90th day being referred to herein as
the "Filing Deadline"), (ii) use its best efforts to cause such Exchange Offer
     ---------------                                                          
Registration Statement to become effective at the earliest practicable time, but
in no event later than 180 days

                                       4
<PAGE>
 
after the Closing Date (such 180th day being referred to herein as the
"Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all
 ----------------------
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the New Preferred Stock or
the New Exchange Notes, as the case may be, to be made under the Blue Sky laws
of such jurisdictions as are necessary to permit Consummation of the Exchange
Offer, and (iv) upon the effectiveness of such Exchange Offer Registration
Statement, commence and Consummate the Exchange Offer. The Exchange Offer shall
be on the appropriate form permitting registration of the New Preferred Stock or
the New Exchange Notes, as the case may be, to be offered in exchange for the
Preferred Stock or the Exchange Notes, as the case may be, that are Transfer
Restricted Securities and to permit resales of New Preferred Stock and New
Exchange Notes, as the case may be, by Broker-Dealers as contemplated by
Section 3(c) below.

     (b)  The Company shall use its reasonable best efforts to cause the
Exchange Offer Registration Statement to be effective continuously, and shall
keep the Exchange Offer open for a period of not less than the minimum period
required under applicable federal and state securities laws to Consummate the
Exchange Offer; provided, however, that in no event shall such period be less
than 20 Business Days.  The Company shall cause the Exchange Offer to comply
with all applicable federal and state securities laws.  No securities other than
the Preferred Stock or the Exchange Notes, as the case may be, shall be included
in the Exchange Offer Registration Statement.  The Company shall use its
reasonable best efforts to cause the Exchange Offer to be Consummated on the
earliest practicable date after the Exchange Offer Registration Statement has
become effective, but in no event later than 210 days after the Closing Date.

     (c)  The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Transfer Restricted
Securities acquired directly from the Company or any Affiliate of the Company),
may exchange such Transfer Restricted Securities pursuant to the Exchange Offer;
however, such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with any resales of any New Preferred
Stock or any New Exchange Notes, as the case may be, received by such Broker-
Dealer in the Exchange Offer and that the Prospectus contained in the Exchange
Offer Registration Statement may be used to satisfy such prospectus delivery
requirement.  Such "Plan of Distribution" section shall also contain all other
information with respect to such sales by such Broker-Dealers that the
Commission may require in order to permit such sales pursuant thereto, but such
"Plan of Distribution" shall not name any such Broker-Dealer or disclose the
amount of Transfer Restricted Securities held by any such Broker-Dealer, except
to the extent required by the Commission.

                                       5

     To the extent necessary to ensure that the Exchange Offer Registration
Statement is available for resales of Transfer Restricted Securities by Broker-
Dealers that were acquired for the account of such Broker-Dealers as a result of
market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Company or any Affiliate of the
Company), the Company agrees to use its best efforts to keep the Exchange Offer
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) hereof and in conformity with the
requirements of this Agreement, the Act and the policies, rules and regulations
of the Commission as announced from time to time, for a period of one year from
the date on which the Exchange Offer is Consummated, or such shorter period as
will terminate when all Transfer Restricted Securities covered by such
Registration Statement have been sold pursuant thereto.  The Company shall
promptly provide sufficient copies of the latest version of such Prospectus to
such Broker-Dealers promptly upon request at any time during such period.

SECTION 4.  SHELF REGISTRATION

     (a)  Shelf Registration.  If (i) the Exchange Offer is not permitted by
          ------------------                                                
applicable law or Commission policy (after the Company has complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the Consummation of the Exchange Offer that (A) such Holder was prohibited by
law or Commission policy from participating in the Exchange Offer or (B) such
Holder may not resell the New Preferred Stock or the New Exchange Notes, as the
case may be, acquired by it in the Exchange Offer to the public without
delivering a prospectus and the Prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such
Holder or (C) such Holder is a Broker-Dealer and holds Transfer Restricted
Securities acquired directly from the Company or any of its Affiliates, then the
Company shall:

     (x) use its reasonable best efforts to cause to be filed, on or prior to 30
days after the earlier of (i) the date on which the Company determines that the
Exchange Offer Registration Statement cannot be filed as a result of clause
(a)(i) above and (ii) the date on which the Company receives the notice
specified in clause (a) (ii) above (such earlier date being referred to herein
as the "Filing Deadline"), a shelf registration statement pursuant to Rule 415
        ---------------                                                       
under the Act (which may be an amendment to the Exchange Offer Registration
Statement (the "Shelf Registration Statement")), relating to all Transfer
                ----------------------------                             
Restricted Securities, and

     (y) use its reasonable best efforts to cause such Shelf Registration
Statement to become effective on or prior to 180 days after the Filing Deadline
(such 180th day being referred to herein the "Effectiveness Deadline").
                                              ----------------------   

     If, after the Company has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) above, the Company is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law, then the filing of
the Exchange Offer Registration Statement shall be deemed to

                                       6
<PAGE>
 
satisfy the requirements of clause (x) above; provided that, in such event, the
Company shall remain obligated to meet the Effectiveness Deadline set forth in
clause (y).

     The Company shall use its best efforts to keep any Shelf Registration
Statement required by this Section 4(a) continuously effective, supplemented and
amended as required by, and subject to the provisions of, Sections 6(b) and (c)
hereof to the extent necessary to ensure that it is available for sales of
Transfer Restricted Securities by the Holders thereof entitled to the benefit of
this Section 4(a), and to ensure that it conforms with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years (as extended
pursuant to Section 6(c)(i)) following the date on which such Shelf Registration
Statement first becomes effective under the Act, or such shorter period as will
terminate when all Transfer Restricted Securities covered by such Registration
Statement have been sold pursuant thereto.

     (b)  Provision by Holders of Certain Information in Connection with the
          ------------------------------------------------------------------
Shelf Registration Statement.  No Holder of Transfer Restricted Securities may
- ----------------------------                                                  
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  Each selling Holder
agrees to promptly furnish additional information required to be disclosed in
order to make the information previously furnished to the Company by such Holder
not materially misleading.

SECTION 5.  SPECIAL DIVIDENDS AND SPECIAL INTEREST

     If (i) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (ii) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not
been Consummated within 210 days after the Closing Date or (iv) any Registration
Statement required by this Agreement is filed and declared effective but shall
thereafter cease to be effective or fail to be usable for its intended purpose
without being succeeded immediately by a post-effective amendment to such
Registration Statement that cures such failure and that is itself declared
effective immediately (each such event referred to in clauses (i) through (iv),
a "Registration Default"), then the Company hereby agrees to pay to each Holder
   --------------------                                                        
of Transfer Restricted Securities affected thereby special dividends ("Special
                                                                       -------
Dividends") or special interest ("Special Interest"), as the case may be, which
- ---------                         ----------------                             
will accrue and be payable semi-annually on the Securities or the Notes (in
addition to the stated dividends on the Securities or the stated interest on the
Notes, as the case may be), as the case may be, from and including the date such
Registration Default occurs to, but excluding, the date on which (1) the
Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement) is filed, in the case of (i) above, (2) the Exchange
Offer Registration Statement (and/or, if applicable, the Shelf Registration
Statement) is declared effective, in the case of (ii) above, (3) the Exchange
Offer is Consummated, in the case of (iii) above, or (4) a post-effective
amendment to the 

                                       7
<PAGE>
 
Registration Statement or an additional Registration Statement is filed that
causes the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement) to again be declared effective or made usable, in
the case of (iv) above. During the time that Special Dividends or Special
Interest, as the case may be, are accruing continuously, the rate of such
Special Dividends or Special Interest, as the case may be, shall be 0.50% per
annum during the first 90-day period and shall increase by 0.25% per annum for
each subsequent 90-day period, but in no event shall such rate exceed 1.00% per
annum in the aggregate regardless of the number of Registration Defaults. If,
after the cure of all Registration Defaults then in effect, there is a
subsequent Registration Default, the Special Dividend rate or Special Interest
rate, as the case may be, for such subsequent Registration Default shall
initially be 0.25%, regardless of the Special Dividend rate or Special Interest
rate, as the case may be, in effect with respect to any prior Registration
Default at the time of the cure of such Registration Default. All accrued
Special Dividends or Special Interest, as the case may be, shall be paid to the
Holders entitled thereto, in the manner provided for the payment of dividends as
set forth in the Memorandum of Increase or in the manner provided for the
payment of interest as set forth in the Indenture, as the case may be. All
obligations of the Company set forth in this paragraph that are outstanding with
respect to any Transfer Restricted Security at the time such security ceases to
be a Transfer Restricted Security shall survive until such time as all such
obligations with respect to such Transfer Restricted Security shall have been
satisfied in full.

SECTION 6.  REGISTRATION PROCEDURES

     (a)  Exchange Offer Registration Statement.  In connection with the
          -------------------------------------                         
Exchange Offer, the Company shall comply with all applicable provisions of
Section 6(c) below, shall use its best efforts to effect such exchange and to
permit the resale of New Preferred Stock or New Exchange Notes, as the case may
be, by Broker-Dealers that tendered in the Exchange Offer Preferred Stock or
Exchange Notes, as the case may be, that such Broker-Dealer acquired for its own
account as a result of its market-making activities or other trading activities
(other than Preferred Stock or Exchange Notes acquired directly from the Company
of any of its Affiliates) being sold in accordance with the intended method or
methods of distribution thereof, and shall comply with all of the following
provisions:

          (i) If, following the date hereof there has been announced a change in
     Commission policy with respect to exchange offers such as the Exchange
     Offer, that in the reasonable opinion of counsel to the Company raises a
     substantial question as to whether the Exchange Offer is permitted by
     applicable federal law, the Company hereby agrees to seek a no-action
     letter or other favorable decision from the Commission, including oral
     advice from the staff of the Commission, allowing the Company to Consummate
     an Exchange Offer for such Transfer Restricted Securities.  The Company
     hereby agrees to pursue the issuance of such a decision to the Commission
     staff level but shall not be required to take commercially unreasonable
     action to effect a change of Commission policy.  In connection with the
     foregoing, the Company hereby agrees to take all such other actions as may
     be requested by the Commission or otherwise required in connection with the
     issuance of such decision, including, without limitation, (A)

                                       8
<PAGE>
 
     participating in telephonic conferences with the Commission, (B) delivering
     to the Commission staff an analysis prepared by counsel to the Company
     setting forth the legal bases, if any, upon which such counsel has
     concluded that such an Exchange Offer should be permitted and (C)
     diligently pursuing a resolution (which need not be favorable) by the
     Commission staff.

          (ii) As a condition to its participation in the Exchange Offer, each
     Holder of Transfer Restricted Securities (including, without limitation,
     any Holder who is a Broker-Dealer) shall furnish, upon the request of the
     Company, prior to the Consummation of the Exchange Offer, a written
     representation to the Company (which may be contained in the letter of
     transmittal contemplated by the Exchange Offer Registration Statement) to
     the effect that (A) it is not an Affiliate of the Company, (B) it is not
     engaged in, and does not intend to engage in, and has no arrangement or
     understanding with any person to participate in, a distribution of the New
     Preferred Stock or New Exchange Notes, as the case may be, to be issued in
     the Exchange Offer and (C) it is acquiring the New Preferred Stock or the
     New Exchange Notes, as the case may be, in its ordinary course of business.
     Each Holder using the Exchange Offer to participate in a distribution of
     the New Preferred Stock or New Exchange Notes, as the case may be, hereby
     acknowledges and agrees that, if the resales thereof are of securities
     obtained by such Holder in exchange for securities acquired directly from
     the Company or an Affiliate thereof, it (1) could not, under Commission
     policy as in effect on the date of this Agreement, rely on the position of
     the Commission enunciated in Morgan Stanley and Co., Inc. (available
                                  ----------------------------                
     June 5, 1991) and Exxon Capital Holdings Corporation (available May 13,
                       ----------------------------------       
     1988), as interpreted in the Commission's letter to Shearman & Sterling
                                                         -------------------
     dated July 2, 1993, and similar no-action letters (including, if
     applicable, any no-action letter obtained pursuant to clause (i) above),
     and (2) must comply with the registration and prospectus delivery
     requirements of the Act in connection with a secondary resale transaction
     and that such a secondary resale transaction must be covered by an
     effective registration statement containing the selling security holder
     information required by Item 507 or 508, as applicable, of Regulation S-K.

          (iii) Prior to effectiveness of the Exchange Offer Registration

Section 6(c) below and shall use its best efforts to effect such registration to
permit the sale of the Transfer Restricted Securities being sold in accordance
with the intended method or methods of distribution thereof (as indicated in the

     (c)  General Provisions.  In connection with any Registration Statement
          ------------------                                                    
and any related Prospectus required by this Agreement, the Company shall:

          (i) use its best efforts to keep such Registration Statement
     continuously effective and provide all requisite financial statements for
     the period specified in Section 3 or 4 of this Agreement, as applicable.
     Upon the occurrence of any event that would cause any such Registration
     Statement or the Prospectus contained therein (A) to contain a material
     misstatement or omission or (B) not to be effective and usable for resale
     of Transfer Restricted Securities during the period required by this
     Agreement, the Company shall file promptly an appropriate amendment to such
     Registration Statement curing such defect, and, if Commission review is
     required, use its best efforts to cause such amendment to be declared
     effective as soon as reasonably practicable thereafter.

          (ii) prepare and file with the Commission such amendments and post-
     effective amendments to the applicable Registration Statement as may be
     necessary to keep such Registration Statement effective for the applicable
     period set forth in Section 3 or 4 hereof, as the case may be, or such
     shorter period as will terminate when all Transfer Restricted Securities
     covered by such Registration Statement have been exchanged or sold or until
     such Transfer Restricted Securities no longer constitute Transfer
     Restricted Securities or are no longer outstanding; cause the Prospectus to
     be supplemented by any required Prospectus supplement, and as so
     supplemented to be filed pursuant to Rule 424 under the Act, and to comply
     fully with Rules 424, 430A and 462, as applicable, under the Act in a
     timely manner; and comply with the provisions of the Act with respect to
     the disposition of all securities covered by such Registration Statement
     during the applicable period in accordance with the intended method or
     methods of distribution by the sellers thereof set forth in such
     Registration Statement or supplement to the Prospectus;

                                       10
<PAGE>
 
          (iii) advise the selling Holders promptly and, if requested by such
     Persons, confirm such advice in writing, (A) when the Prospectus or any
     Prospectus supplement or post-effective amendment has been filed, and, with
     respect to any applicable Registration Statement or any post-effective
     amendment thereto, when the same has become effective, (B) of any request
     by the Commission for amendments to the Registration Statement or
     amendments or supplements to the Prospectus or for additional information
     relating thereto, (C) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement under the Act or
     of the suspension by any state securities commission of the qualification
     of the Transfer Restricted Securities for offering or sale in any
     jurisdiction, or the initiation of any proceeding for any of the preceding
     purposes, or (D) of the existence of any fact or the happening of any event
     that makes any statement of a material fact made in the Registration
     Statement, the Prospectus, any amendment or supplement thereto or any
     document incorporated by reference therein untrue, or that requires the
     making of any additions to or changes in the Registration Statement in
     order to make the statements therein not misleading, or that requires the
     making of any additions to or changes in the Prospectus in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. If at any time the Commission shall issue any
     stop order suspending the effectiveness of the Registration Statement, or
     any state securities commission or other regulatory authority shall issue
     an order suspending the qualification or exemption from qualification of
     the Transfer Restricted Securities under state securities or Blue Sky laws,
     the Company shall use its best efforts to obtain the withdrawal or lifting
     of such order at the earliest practicable time;

          (iv) subject to Section 6(c)(i), if any fact or event contemplated by
     Section 6(c)(iii)(D) above shall exist or have occurred, prepare a
     supplement or post-effective amendment to the Registration Statement or
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of Transfer Restricted Securities, the Prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (v) furnish to the Initial Purchasers and each selling Holder named in
     any Registration Statement or Prospectus in connection with such sale, if
     any, before filing with the Commission, copies of any Registration
     Statement or any Prospectus included therein or any amendments or
     supplements to any such Registration Statement or Prospectus (including all
     documents incorporated by reference, if requested by such person), which
     documents will be subject to the review and comment of such Holders in
     connection with such sale, if any, for a period of at least five Business
     Days, and the Company will not file any such Registration Statement or
     Prospectus or any amendment or supplement to any such Registration
     Statement or Prospectus (including all such documents incorporated by
     reference, if requested by such person) to which the selling Holders of the
     Transfer Restricted Securities covered by such Registration Statement in

                                       11
<PAGE>
 
     connection with such sale, if any, shall reasonably object within five
     Business Days after the receipt thereof. A selling Holder shall be deemed
     to have reasonably objected to such filing if such Registration Statement,
     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains a material misstatement or omission or fails to comply with
     the applicable requirements of the Act;

          (vi) promptly prior to the filing of any document that is to be
     incorporated by reference into a Registration Statement or Prospectus, if
     requested by any selling Holders within five Business Days after receipt of
     notification thereof from the Company, provide copies of such document to
     such selling Holders in connection with such sale, if any, make the
     Company's' representatives available for discussion of such document and
     other customary due diligence matters, and include such information in such
     document prior to the filing thereof as such selling Holders may reasonably
     request;

          (vii) make available at reasonable times for inspection by the selling
     Holders participating in any disposition pursuant to such Registration
     Statement and any attorney or accountant retained by such selling Holders,
     all financial and other records, pertinent corporate documents of the
     Company and cause the Company's officers, directors and employees to supply
     all information reasonably requested by any such selling Holder, attorney
     or accountant in connection with such Registration Statement or any post-
     effective amendment thereto subsequent to the filing thereof and prior to
     its effectiveness;

          (viii) if requested by any selling Holders in connection with such
     sale, if any, promptly include in any Registration Statement or Prospectus,
     pursuant to a supplement or post-effective amendment if necessary, such
     information as such selling Holders may reasonably request to have included
     therein, including, without limitation, information relating to the "Plan
     of Distribution" of the Transfer Restricted Securities; and make all
     required filings of such Prospectus supplement or post-effective amendment
     as soon as practicable after the Company is notified of the matters to be
     included in such Prospectus supplement or post-effective amendment;

          (ix) furnish to each selling Holder in connection with such sale, if
     any, without charge, at least one copy of the Registration Statement, as
     first filed with the Commission, and of each amendment thereto, including
     all documents incorporated by reference therein and all exhibits (including
     exhibits incorporated therein by reference);

          (x) deliver to each selling Holder, without charge, as many copies of
     the Prospectus (including each preliminary prospectus) and any amendment or
     supplement thereto as such Persons reasonably may request; the Company
     hereby consents to the use (in accordance with law) of the Prospectus and
     any amendment or supplement thereto by each of the selling Holders in
     connection with the offering and the sale of the Transfer Restricted
     Securities covered by the Prospectus or any amendment or supplement
     thereto;

          (xi) upon the request of any selling Holder, enter into such
     agreements (including underwriting agreements) and make such
     representations and warranties and

                                       12
<PAGE>
 
     take all such other actions in connection therewith in order to expedite or
     facilitate the disposition of the Transfer Restricted Securities pursuant
     to any applicable Registration Statement contemplated by this Agreement,
     all to such extent as may be reasonably acceptable to the Company and as
     may be reasonably requested by any Holder of Transfer Restricted Securities
     in connection with any sale or resale pursuant to any applicable
     Registration Statement contemplated by this Agreement and in such
     connection, the Company shall:

          (A) upon request of any selling Holder, furnish (or in the case of
       paragraphs (2) and (3), use its best efforts to cause to be furnished) to
       each selling Holder, upon the effectiveness of the Shelf Registration
       Statement or upon Consummation of the Exchange Offer, as the case may be:

               (1) a certificate, dated such date, signed on behalf of the
          Company by (x) the Chief Executive Officer, President or any Vice
          President and (y) a principal financial or accounting officer of the
          Company, confirming, as of the date thereof, the matters set forth in
          paragraph (f) of Section 6 of the Purchase Agreement and such other
          similar matters as the selling Holders may reasonably request;

               (2) opinions, dated such date, of counsel for the Company
          covering matters similar to those set forth in paragraphs (a), (b),
          (c) and (d) of Section 6 of the Purchase Agreement and such other
          matters as the selling Holders may reasonably request, and in any
          event including a statement to the effect that certain such counsel
          has participated in conferences with officers and other
          representatives of the Company and representatives of the independent
          public accountants for the Company at which the contents of such
          Registration Statement and the related Prospectus were discussed,
          although such counsel has not independently verified the accuracy,
          completeness or fairness of such statements; and that such counsel
          advises that, on the basis of the foregoing, no facts came to such
          counsel's attention that caused such counsel to believe that the
          applicable Registration Statement, at the time such Registration
          Statement or any post-effective amendment thereto became effective
          and, in the case of the Exchange Offer Registration Statement, as of
          the date of Consummation of the Exchange Offer, contained an untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, or that the Prospectus contained in such
          Registration Statement as of its date and, in the case of the opinion
          dated the date of Consummation of the Exchange Offer, as of the date
          of Consummation, contained an untrue statement of a material fact or
          omitted to state a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading.  Without limiting the foregoing, such
          counsel may state further that such counsel assumes no responsibility
          for, and has not independently verified, the accuracy, completeness or
          fairness of the

                                       13
<PAGE>
 
          financial statements, notes and schedules and other financial data
          included in any Registration Statement contemplated by this Agreement
          or the related Prospectus; and

               (3) a customary comfort letter, dated such date, from the
          Company's independent accountants, in the customary form and covering
          matters of the type customarily covered in comfort letters to
          underwriters in connection with underwritten offerings, and affirming
          the matters set forth in the comfort letters delivered pursuant to
          Section 6(g) of the Purchase Agreement; and

          (B) deliver such other documents and certificates as may be reasonably
       requested by the selling Holders to evidence compliance with clause (A)
       above and with any customary conditions contained in the any agreement
       entered into by the Company pursuant to this clause (xi);

          (xii) prior to any public offering of Transfer Restricted Securities,
     cooperate with the selling Holders and their counsel in connection with the
     registration and qualification of the Transfer Restricted Securities under
     the securities or Blue Sky laws of such jurisdictions as the selling
     Holders may reasonably request and do any and all other acts or things
     necessary or advisable to enable the disposition in such jurisdictions of
     the Transfer Restricted Securities covered by the applicable Registration
     Statement; provided, however, that the Company shall not be required to
     register or qualify as a foreign corporation where it is not now so
     qualified or to take any action that would subject it to the service of
     process in suits or to taxation, other than as to matters and transactions
     relating to the Registration Statement, in any jurisdiction where it is not
     now so subject;

          (xiii) issue, upon the request of any Holder of Preferred Stock or
     Exchange Notes, as the case may be, covered by any Shelf Registration
     Statement contemplated by this Agreement, New Preferred Stock or New
     Exchange Notes, as the case may be, having the same aggregate Liquidation
     Preference as the aggregate Liquidation Preference of Preferred Stock, or
     an aggregate principal amount equal to the aggregate principal amount of
     Exchange Notes, as applicable, in each case surrendered to the Company by
     such Holder in exchange therefor or being sold by such Holder; such New
     Preferred Stock or New Exchange Notes, as the case may be, to be registered
     in the name of such Holder or in the name of the purchaser(s) of such New
     Preferred Stock or New Exchange Notes, as the case may be; in return, the
     Preferred Stock or the Exchange Notes, as the case may be, held by such
     Holder shall be surrendered to the Company for cancellation;

          (xiv) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the selling Holders to facilitate the timely
     preparation and delivery of certificates representing Transfer Restricted
     Securities to be sold and not bearing any restrictive legends; and to

                                       14
<PAGE>
 
     register such Transfer Restricted Securities in such denominations and such
     names as the selling Holders may request at least two Business Days prior
     to such sale of Transfer Restricted Securities;

          (xv) use its best efforts to cause the disposition of the Transfer
     Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof to
     consummate the disposition of such Transfer Restricted Securities, subject

     Trustee, as the case may be, with printed certificates for the Transfer
     Restricted Securities which are in a form eligible for deposit with the
     Depository Trust Company;

          (xvii) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make generally available to
     Holders with regard to any applicable Registration Statement, as soon as
     practicable, a consolidated earnings statement meeting the requirements of
     Rule 158 under the Act (which need not be audited) covering a twelve-month
     period beginning after the effective date of the Registration Statement (as
     such term is defined in paragraph (c) of Rule 158 under the Act);

          (xviii) make appropriate officers of the Company available to the
     selling Holders for meetings with prospective purchasers of the Transfer
     Restricted Securities; and

          (xix) if Notes are being included in any Registration Statement,

     effective date of the first Registration Statement required by this
     Agreement and, in connection therewith, cooperate with the Trustee and the
     Holders to effect such changes to the Indenture as may be required for the
     Indenture to be so qualified in accordance with the terms of the TIA; and
     execute and use its best efforts to cause the Trustee to execute all
     documents that may be required to effect such changes and all other forms
     and documents required to be filed with the Commission to enable such
     Indenture to be so qualified in a timely manner; and

          (xx) provide promptly to each Holder upon request each document filed

          (d) Restrictions on Holders.  Each Holder agrees by acquisition of a
              -----------------------                                         
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(i) or any notice from the Company of the existence of any fact of
the kind described in Section 6(c)(iii)(D) hereof (in each case, a "Suspension
                                                                    ----------

information relating to such Indemnified Holder furnished to the Company by such
Indemnified Holder specifically for inclusion in any Registration Statement,
preliminary prospectus or Prospectus (or in any amendment or supplement
thereto).  This indemnity agreement will be in addition to any liability which
any Indemnified Holder may otherwise have.

                                       17

     (c)  Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all indemnified
parties, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for the Indemnified Holder and such control
persons shall be designated in writing by a majority of the Indemnified Holders
and any such separate firm of the Company, its directors, its officers and such
control persons of the Company shall be designated in writing by the Company. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

     (d)  In the event that the indemnity provided in paragraph (a) or (b) of
this Section 8 is unavailable to hold harmless an indemnified party for any
reason, the Company, and the Holders agree to contribute to the aggregate
losses, claims, damages and liabilities (including legal or other expenses
reasonably incurred in connection with investigating or defending same)

                                       18

(collectively "Losses") to which the Company and one or more of the Holders may
               ------                                                          
be subject in such proportion as is appropriate to reflect the relative benefits
received by the Company, on the one hand, and by the Indemnified Holders, on the
other hand, from the sale of Transfer Restricted Securities; provided, however,
that in no case shall any Holder (except as may be provided in any agreement
among the Holders relating to the sale of its Transfer Restricted Securities) be
responsible for any amount in excess of the amount by which the total received
by such Holder with respect to its sale of Transfer Restricted Securities
pursuant to a Registration Statement exceeds the sum of (A) the amount paid to
such Holder for such Transfer Restricted Securities plus (B) the amount of any
damages which such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. If the
allocation provided by the immediately preceding sentence is unavailable for any
reason, the Company and the Indemnified Holder shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company, on the one hand, and of the Indemnified
Holder, on the other hand, in connection with the statements or omissions which
resulted in such Losses as well as any other relevant equitable considerations.
Relative fault shall be determined by reference to whether any alleged untrue
statement or omission relates to information provided by either the Company or
the Holders and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and each Holder agree that it would not be just and equitable if contribution
were determined by pro rata allocation or any other method of allocation which
does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, each person who
controls a Holder within the meaning of either the Act or the Exchange Act and
each director, officer, employee and agent of a Holder shall have the same
rights to contribution as such Holder, and each person who controls the Company
within the meaning of either the Act or the Exchange Act and each officer and
director of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (d). The remedies provided in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

SECTION 9.  RULE 144A

     The Company hereby agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder of Transfer Restricted Securities, to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of such Transfer Restricted
Securities designated by such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A.

SECTION 10.  MISCELLANEOUS

                                       19

          (a) Remedies.  The Company acknowledges and agrees that any failure
              --------                                               
by the Company to comply with its obligations under Sections 3 and 4 hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, any Initial Purchaser or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 3 and
4 hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

          (b) No Inconsistent Agreements.  The Company shall not, on or after
              --------------------------            
the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under any agreement in effect on the date hereof.

          (c) Amendments and Waivers.  The provisions of this Agreement may not
              ----------------------                                        
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section10 (c)(i), the Company has obtained the written consent
of the Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of the Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities (excluding Transfer Restricted Securities held by
the Company of its Affiliates). Notwithstanding the foregoing, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders whose securities are being tendered pursuant to the Exchange
Offer or registered pursuant to the Shelf Registration Statement and that does
not affect, directly or indirectly, the rights of other Holders whose securities
are not being tendered pursuant to such Exchange Offer or registered pursuant to
the Shelf Registration Statement may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer or such Shelf Registration Statement, as applicable.

          (d) Third Party Beneficiary.  The Holders shall be third party
              -----------------------                                   
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect their rights or the rights of Holders
hereunder.

          (e) Notices.  All notices and other communications provided for or
              -------

benefit of and be binding upon the successors and assigns of each of the parties
hereto, including, without limitation, and without the need for an express
assignment, subsequent Holders of Transfer Restricted Securities; provided, that
nothing herein shall be deemed to permit any assignment, transfer or other
disposition of Transfer Restricted Securities in violation of the terms hereof
or of the Purchase Agreement, the Memorandum of Increase, Bye-laws or the
Indenture. If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Transfer Restricted Securities, such
Person shall be conclusively deemed to have agreed to be bound by and to perform

when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

reference only and shall not limit or otherwise affect the meaning hereof.

          (i) Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED 
              -------------                                      
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          (j) Severability.  In the event that any one or more of the provisions
              ------------                                                      
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

          (k) Entire Agreement.  This Agreement is intended by the parties as a
              ----------------                                                 
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein.  There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted with respect to the Transfer
Restricted Securities.  This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

          (l) Consent to Jurisdiction and Service.  To the fullest extent
              ------------------------------------                        
permitted by applicable law, the Company hereby irrevocably submits to the
jurisdiction of any Federal or State court located in the Borough of Manhattan
in The City of New York, New York in any suit, action or proceeding based on or
arising out of or relating to this Agreement or any Securities or Notes, and
irrevocably agrees that all claims in respect of such suit or proceeding may be
determined in any such court. The Company irrevocably waives, to the fullest
extent permitted by law, any objection which it may have to the laying of the
venue of any such suit, action or proceeding brought in such a court and any
claim that any suit, action or proceeding brought in such a court has been
brought in an inconvenient forum. The Company agrees that final judgment in any
such suit, action or proceeding brought in such a court shall be conclusive and
binding upon the Company and may be enforced in the courts of Bermuda (or any
other courts to the jurisdiction of which the Company is subject) by a suit upon
such judgment, provided that service of process is effected upon the Company in
               --------
the manner specified herein or as otherwise permitted by law. The Company hereby
irrevocably designates and appoints CT Corporation System, 1633 Broadway - 23rd
Floor, New York, New York (the "Process Agent"), as the authorized agent of the
                                ------------- 
Company upon whom process may be served in any such suit or proceeding, it being
understood that the designation and appointment of the Process Agent as such
authorized agent shall become effective immediately without any further action
on the part of the Company. The Company hereby represents to each Initial
Purchaser that it has notified the Process Agent of such designation and
appointment and that the Process Agent has accepted the same in writing. The
Company hereby irrevocably authorizes and directs the Process Agent to accept
such service. The Company further agrees that service of process upon the
Process Agent and written notice of said service to the Company mailed by
prepaid registered first class mail or delivered to the Process Agent at its
principal office, shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect the
right of any 

                                       22
<PAGE>
 
Initial Purchaser or any person controlling any Initial Purchaser to serve
process in any other matter permitted by law. The Company further agrees to take
any and all action, including the execution and filing of any and all such
documents and instruments as may be necessary to continue such designation and
appointment of the Process Agent in full force and effect so long as the Company
has any outstanding obligations under this Agreement, the Securities, the Notes,
the Memorandum of Increase, Bye-laws or the Indenture. To the extent that the
Company has or hereafter may acquire any immunity from jurisdiction of any court
or from any legal process (whether through service of note, attachment prior to
judgment, attachment in aid of execution, executor or otherwise) with respect to
itself or its property, the Company hereby irrevocably waives such immunity in
respect of its obligations under this Agreement, to the extent permitted by law.

payable as of such Termination Date, and the Administrative Agent shall deposit
the proceeds of such Borrowings in the Clean-Up Sub-Account pursuant to the
provisions of the Securities Accounts Agreement.  The amount to be so requested
shall be equal to the lesser of (i) the aggregate amount of the Tranche A-1 Term
Loan Commitment so remaining available and (ii) the aggregate estimated amount
of such Final Contractor Payment and other Capital Costs.  After giving effect
to the foregoing, contemporaneously with or immediately prior to the Termination
Date with respect to the Tranche A-1 Term Loans the Borrower may submit a Credit
Extension Request requesting a Borrowing of Tranche A-1 Term Loans for deposit
into the Backhaul Account in an amount not to exceed the lesser of (a) the
aggregate amount of the Tranche A-1 Term Loan Commitment so remaining available
and (b) the then available Unrestricted Contingency, if any.

     SECTION 2.05.  Funding Of Borrowings.
                    --------------------- 

          (a) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00
noon, New York City time, to the account of the Administrative Agent most
recently designated by the Administrative Agent for such purpose by notice to
the Lenders.  The Administrative Agent will make such Loans available to the
Borrower by promptly transferring the amounts so received, in like funds, to the
applicable Account pursuant to the provisions of the Securities Accounts
Agreement.

          (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender agrees to pay to the Administrative Agent forthwith on demand
such corresponding amount with interest thereon, for each day from and including
the date such amount is made available to the Borrower to but excluding the date
of payment to the Administrative Agent, at the Federal Funds Effective Rate for
3 days and at the Alternate Base Rate thereafter.  If such Lender pays such
amount to the Administrative Agent, then such amount shall constitute such
Lender's Loan included in such Borrowing.

     SECTION 2.06.  Interest Elections.
                    ------------------ 

          (a) Each Working Capital Borrowing and Term Loan Borrowing initially
shall be of the Type specified in the applicable Credit Extension Request and,
in the case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Credit Extension Request.  Thereafter, the Borrower may elect
to convert such Borrowing to a different Type or to continue such Borrowing and,
in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all
as provided in this Article II.  The Borrower may elect different options with
                    ----------                                                
respect to different portions of the affected Borrowing, in which case each such
portion shall be allocated ratably among the Lenders holding the Loans
comprising such Borrowing, and the Loans comprising each such portion shall be
considered a separate Borrowing.

          (b) To make an election pursuant to this Section, the Borrower shall
notify the Administrative Agent of such election by delivering a
Continuation/Conversion Notice to the Administrative Agent by the time that a
Credit Extension Request would be required under Section 2.03 if the Borrower
                                                 ------------                
were requesting a Borrowing of the Type resulting from such election to be made
on the effective date of such election.  Each such notice shall be irrevocable.

          (c) Each Continuation/Conversion Notice shall specify the following
information in compliance with Section 2.02:
                               ------------ 

               (i)      the Borrowing to which such Continuation/Conversion
     Notice applies and, if different options are being elected with respect to
     different portions thereof, the portions thereof to be allocated to each
     resulting Borrowing (in which case the information to be specified pursuant
     to clauses (iii) and (iv) below shall be specified for each resulting
     Borrowing);

               (ii)     the effective date of the election made pursuant to such
     Continuation/Conversion Notice, which shall be a Business Day;

               (iii)    whether the resulting Borrowing is to be an ABR
     Borrowing or a Eurodollar Borrowing; and

               (iv)     if the resulting Borrowing is a Eurodollar Borrowing,
     the Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period."

If any such Continuation/Conversion Notice requests a Eurodollar Borrowing but
does not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

          (d) Promptly following receipt of a Continuation/Conversion Notice,
the Administrative Agent shall advise each applicable Lender of the details
thereof and of such Lender's portion of each resulting Borrowing.

                                       43
<PAGE>
 
          (e) If the Borrower fails to deliver a timely Continuation/Conversion
Notice with respect to a Eurodollar Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing.  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the
request of the Majority Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Borrowing may be converted to
or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar
Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto.

     SECTION 2.07.  Termination and Reduction of Commitments.
                    ---------------------------------------- 

          (a) Unless previously terminated, each Commitment shall terminate on
the Termination Date in respect thereof.

          (b) The Borrower shall notify the Administrative Agent of any election
to terminate or reduce the Commitments under paragraph (c) of this Section at
least 5 Business Days prior to the effective date of such termination or
reduction, specifying such election and the effective date thereof.  Promptly
following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof.  Each notice delivered by the Borrower pursuant
to this Section 2.07 shall be irrevocable.  Any termination or reduction of the
        ------------                                                           
Commitments shall be permanent.  Each reduction of the Commitments of any Class
shall be made ratably among the Lenders in accordance with their respective
Commitments of such Class.

          (c) The Borrower may at any time terminate, or from time to time
reduce, the Commitments of any Class; provided that (i) each reduction of the
                                      --------                               
Commitments of any Class shall be in an amount that is an integral multiple of
$1,000,000, (ii) the Borrower shall not terminate or reduce the Term Loan
Commitments if the remaining Term Loan Commitments, together with other funds
available to the Borrower, would not, in the reasonable judgment of the
Administrative Agent, be sufficient to pay the remaining amounts owing under the
Supply Contracts and the other costs necessary to complete the System and (iii)
the Borrower shall not terminate or reduce the Tranche A-2 Term Loan Commitment
prior to First Permitted Upgrade Final Completion if the amounts on deposit in
the Upgrade Account (together with other funds available to the Borrower on
terms satisfactory to the Lead Agents) would not, in the reasonable judgment of
the Administrative Agent, be sufficient to pay all costs necessary to complete
the First Permitted Upgrade.

     SECTION 2.08.  Repayment of Loans; Evidence of Debt.
                    ------------------------------------ 

          (a) The Borrower hereby unconditionally promises to repay (i) the
Working Capital Borrowings as set forth under the heading "Working Capital Loan
Amortization Schedule" on Schedule 2.08, (ii) the Tranche A-1 Term Loan
                          -------------

forth under the heading "Tranche A-2 Term Loan Amortization Schedule" on
                                                                        
Schedule 2.08; provided that (1) at no time shall the Borrower be obligated to
- -------------  --------

total 

                                       44
<PAGE>
 
principal of Loans then outstanding hereunder and (2) in the event that
the Borrower did not draw the full amount of any Term Loan Commitment, the
aggregate principal amount of the corresponding Term Loans payable hereunder
shall be reduced by such amount not drawn (such reduction to be applied to then
remaining installments of principal of such Term Loans pro rata).

          (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Loan made by such Lender, including the amounts of
principal and interest payable and paid to such Lender from time to time
hereunder.

          (c) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain the Register pursuant to Section 9.04(c) and a sub-
                                                      ---------------

principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each
Lender's share thereof.

          (d) The entries made in the Register and the accounts maintained
pursuant to paragraph (b) or (c) of this Section shall constitute prima facie
                                                                  ----- -----

provided that the failure of any Lender or the Administrative Agent to maintain
- --------                                                                       
such accounts or any error therein shall not in any manner affect the obligation
of the Borrower to repay the Loans in accordance with the terms of this
Agreement.

          (e) The Borrower agrees that, upon the request to the Administrative
Agent by any Lender, the Borrower will execute and deliver to such Lender, as
applicable, (i) a promissory note of the Borrower payable to the order of such
Lender and its registered assigns evidencing the Tranche A-1 Term Loans of such
Lender and substantially in the form of Exhibit A-1, with appropriate insertions
                                        -----------                             
as to date and principal amount (each, a "Tranche A-1 Term Note"), (ii) a
                                          ---------------------          
promissory note of the Borrower payable to the order of such Lender and its
registered assigns evidencing the Tranche A-2 Term Loans of such Lender and
substantially in the form of Exhibit A-2, with appropriate insertions as to date

and principal amount (each a "Tranche A-2 Term Note") and (iii) a promissory
                              ---------------------                         
note of the Borrower payable to the order of such Lender and its registered
assigns evidencing the Working Capital Loans of such Lender and substantially in
the form of Exhibit A-3, with appropriate insertions as to date and principal
            -----------

                 --------------------                                           
such Note and interest thereon shall at all times (including after assignment
pursuant to Section 9.04) be represented by one or more Notes payable to the
            ------------                                                    
order of the payee named therein and its registered assigns.  A Note and the
obligation evidenced thereby may be assigned or otherwise transferred in whole
or in part only by registration of such assignment or transfer of such Note and
the obligation evidenced thereby in the Register (and each Note shall expressly
so provide).  Any assignment or transfer of all or part of an obligation
evidenced by a Note shall be registered in the Register only upon surrender for
registration of assignment or transfer of the Note evidencing such obligation,
accompanied by an Assignment and Acceptance duly executed by the assignor
thereof, and 

                                       45

thereupon, if requested by the assignee, one or more new Notes shall be issued
to the designated assignee and the old Note shall be returned by the
Administrative Agent to the Borrower marked "canceled." No assignment of a Note
and the obligation evidenced thereby shall be effective unless it shall have
been recorded in the Register by the Administrative Agent as provided in this
Section 2.08(e).

Administrative Agent shall invest funds in any such cash collateral account in
overnight investments constituting Permitted Investments.

     SECTION 2.11.  Fees.
                    ----

account of each Lender a commitment fee, which shall accrue at the rate of 0.75%

during the period from the Closing Date to but excluding the date on which such
Commitment terminates.  Accrued commitment fees shall be payable in arrears on
the last Business Day of each August, November, February and May of each year
and on the date on which the Commitments terminate, commencing on the first such
date to occur after the date hereof.  All commitment fees shall be computed on
the basis of a year of 360 days and shall be payable for the actual number of
days elapsed (including the first day but excluding the last day).  For purposes
of computing commitment fees with respect to the Term Loan Commitments, a Term
Loan Commitment of a Lender shall be deemed to be used to the extent of the
outstanding Term Loans of such Lender.  For purposes of computing commitment
fees with respect to the Working Capital Loan Commitments, a Working Capital
Loan Commitment shall be deemed to be used to the extent of the outstanding
Working Capital Loans of such Lender.

          (b) The Borrower agrees to pay to the Administrative Agent and the
Lead Agents, for their own accounts, the fees payable in the amounts and at the
times separately agreed upon between the Borrower, the Administrative Agent and
the Lead Agents in the Fee Letter.

          (c) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent for distribution to the
Lenders (in the case of paragraph (a) of this Section) or for the account of the
Lead Agents or the Administrative Agent, as the case may be (in the case of
paragraph (b) of this Section).

     SECTION 2.12.  Interest.
                    --------

          (b) The Loans comprising each Eurodollar Borrowing shall bear interest
at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in
effect for such Borrowing plus the Applicable Rate.

          (c) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any

Loan, 2% plus the rate otherwise applicable to such Loan as provided above or
(ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans
as provided above.

          (d) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan; provided that (i) interest accrued pursuant
                                     --------                                   
to paragraph (c) of this Section shall be payable on demand, (ii) in the event
of any repayment or prepayment of any Loan, accrued interest on the principal
amount repaid or prepaid shall be payable on the date of such repayment or
prepayment, (iii) in the event of any conversion of any Eurodollar Borrowing
prior to the end of the current Interest Period therefor, accrued interest on
such Loan shall be payable on the effective date of such conversion and (iv) all
accrued interest shall be payable upon termination of the Commitments.

          (e) All interest hereunder shall be computed on the basis of a year of
360 days, except that interest computed by reference to the Alternate Base Rate
at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day).

     SECTION 2.13.  Alternate Rate of Interest; Illegality.
                    -------------------------------------- 

          (a) If prior to the commencement of any Interest Period for a
Eurodollar Borrowing:

               (i) the Administrative Agent determines (which determination
     shall be conclusive absent manifest error) that adequate and reasonable
     means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO
     Rate, as applicable, for such Interest Period; or

               (ii) the Administrative Agent is advised by the Majority Lenders
     that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such
     Interest Period will not adequately and fairly reflect the cost to such
     Lenders of making or maintaining their Loans included in such Borrowing for
     such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any
Continuation/Conversion Notice that requests the conversion of any Borrowing to,
or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such
Borrowing shall be made as an ABR Borrowing.

          (b) Notwithstanding any other provision of this Agreement, if on or
after the date of this Agreement the adoption of or any change in any applicable
law or in the interpretation or application thereof shall make it unlawful for
any Lender to make or maintain Eurodollar Loans as contemplated by this
Agreement, (i) such Lender shall give telex, telecopy or telephonic notice
thereof to the Administrative Agent and the Borrower as soon as practicable

                                       49
<PAGE>
 
(and, with respect to any such telephonic notice, the party delivering the same
agrees to confirm such notice in writing), (ii) the commitment of such Lender
hereunder to make Eurodollar Loans and continue Eurodollar Loans as such shall
forthwith be canceled and (iii) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to ABR Loans on the
respective last days of the then current Interest Periods with respect to such
Loans or within such earlier period as required by law.  If any such conversion
of a Eurodollar Loan occurs on a day which is not the last day of the then
current Interest Period with respect thereto, the Borrower shall pay to such
Lender such amounts, if any, as may be required pursuant to Section 2.15.
                                                            ------------ 

     SECTION 2.14.  Increased Costs.
                    --------------- 

          (a)  If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special
     deposit or similar requirement against assets of, deposits with or for the
     account of, or credit extended or participated in by, any Lender (except
     any such reserve requirement reflected in the Adjusted LIBO Rate); or

               (ii) impose on any Lender any other condition affecting this
     Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan) or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender such additional amount or
amounts as will compensate such Lender for such additional costs incurred or
reduction suffered.

          (b) If any Lender determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on the
capital of such Lender or any holding company for such Lender as a consequence
of this Agreement or the Loans made by such Lender to a level below that which
such Lender or the holding company for such Lender could have achieved but for
such Change in Law (taking into consideration such Lender's policies with
respect to capital adequacy), then from time to time the Borrower will pay to
such Lender or such Lender's holding company, as the case may be, such
additional amount or amounts as will compensate such Lender for any such
reduction suffered.

          (c) If any Lender becomes entitled to claim compensation pursuant to
this Section, such Lender shall promptly notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.
A certificate of a Lender setting forth the amount or amounts necessary to
compensate such Lender or such holding company, as the case may be, as specified
in paragraph (a) or (b) of this Section delivered to the Borrower (with a copy
to the Administrative Agent), shall constitute prima facie evidence of the
                                               ----- -----                
correctness of the amount claimed.

          (d) The Borrower shall pay such Lender all amounts payable pursuant to
the foregoing provisions of this Section 2.14 within 20 days after receipt of
                                 ------------                                
certification thereof from such Lender.  Failure or delay on the part of any
Lender to demand compensation pursuant to this 

                                       50
<PAGE>
 
Section shall not constitute a waiver of such Lender's right to demand such
compensation; provided that the Borrower shall not be required to compensate a
              --------         
Lender pursuant to this Section for any increased costs or reductions incurred
more than 6 months prior to the date that such Lender notifies the Borrower of
the Change in Law giving rise to such increased costs or reductions and of such
Lender's intention to claim compensation therefor.

     SECTION 2.15.  Break Funding Payments.
                    ---------------------- 

In the event of (a) the payment of any principal of any Eurodollar Loan other
than on the last day of an Interest Period applicable thereto, (b) the
conversion of any Eurodollar Loan other than on the last day of the Interest
Period applicable thereto or (c) the failure to borrow, convert, continue or
prepay any Eurodollar Loan on the date specified in any notice delivered
pursuant hereto, then, in any such event, the Borrower shall compensate each
Lender for the loss, cost and expense attributable to such event.  In the case
of a Eurodollar Loan, the loss to any Lender attributable to any such event
shall be equal to the excess, if any, of (i) the amount of interest that such
Lender would pay for a deposit equal to the principal amount of such Loan for
the period from the date of such payment, conversion or failure to the last day
of the then current Interest Period for such Loan (or, in the case of a failure
to borrow, convert or continue, the duration of the Interest Period that would
have resulted from such borrowing, conversion or continuation) if the interest
rate payable on such deposit were equal to the Adjusted LIBO Rate for such
Interest Period, over (ii) the amount of interest that such Lender would earn on
such principal amount for such period if such Lender were to invest such
principal amount for such period at the interest rate that would be bid by such
Lender (or an affiliate of such Lender) for dollar deposits from other banks in
the eurodollar market at the commencement of such period.  A certificate of any
Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section shall be delivered by such Lender to the
Borrower (with a copy to the Administrative Agent) and shall constitute prima
                                                                        -----
facie evidence of the correctness of the amount claimed.
- -----                                                   

     SECTION 2.16.  Taxes.
                    ----- 

          (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
                                  --------                              
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent or Lender (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

          (c) The Borrower shall indemnify the Administrative Agent and each
Lender for the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent or such Lender, as the case may be, and any penalties,
interest and reasonable expenses arising 

                                       51
<PAGE>
 
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Borrower by a Lender or by the Administrative Agent
on its own behalf or on behalf of a Lender, shall constitute prima facie
                                                             ----- ----- 
evidence of the correctness of the amount claimed.

          (d) As soon as reasonably practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower
shall deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

          (e) Each Lender that is not a United States Person, as defined in
Section 7701(a)(30) of the Code (a "Non-U.S. Holder"), on or prior to the date
                                    ---------------                           
of its execution and delivery of this Agreement or on the date of the Assignment
and Acceptance pursuant to which it becomes a Lender, as the case may be, and
from time to time thereafter if requested in writing by the Borrower or the
Administrative Agent (but only so long as such Lender remains lawfully able to
do so), shall provide the Borrower and the Administrative Agent with Internal
Revenue Service Form 1001 or 4224, as appropriate, or any successor or other
form prescribed by the Internal Revenue Service, certifying that such Lender is
exempt from or entitled to a reduced rate of United States withholding tax on
payments of interest pursuant to this Agreement or the Notes or, in the case of
any such Lender that is unable to provide an Internal Revenue Service Form 1001
or 4224 and that claims exemption from U.S. Federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of "portfolio
interest," a Form W-8, or any subsequent versions thereof or successors thereto
(and if such Lender delivers a Form W-8, a certificate substantially in the form
of Exhibit N attached hereto).  Any Lender that is legally entitled to an
   ---------                                                             
exemption from or reduction of withholding tax which is an Indemnified Tax with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times reasonably requested by
the Borrower or at such times as are otherwise prescribed by applicable law,
such properly completed and executed documentation prescribed by applicable law
as will permit such payments to be made without withholding or subject to
withholding at a reduced rate.  Each Lender further agrees to deliver to the
Borrower and the Administrative Agent the documentation referred to in the
preceding sentence on or before the date such documentation expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent such documentation previously delivered to the Borrower, so that in each
case payments will be permitted to be made hereunder without withholding or
subject to withholding at a reduced rate.  If any form or document referred to
in this paragraph (e) requires the disclosure of information (other than
information necessary to compute the tax payable or information required by the
relevant taxing authority to secure such exemption or reduction with respect to
withholding tax and that is necessary to secure such exemption from or reduction
of withholding tax) that the Lender reasonably considers to be confidential, the
Lender shall give notice thereof to the Borrower and shall not be obligated to
include in such form or document such confidential information.

                                       52

          (f) If a Lender or the Administrative Agent shall become aware that it
is entitled to receive a refund in respect of an Indemnified Tax paid by the
Borrower, which refund in the good faith judgment of such Lender is allocable to
such payment made by the Borrower pursuant to this Section, it shall promptly
notify the Borrower of the availability of such refund and shall, within 30 days
after the receipt of a request by the Borrower, apply for such refund.  If any
Lender or the Administrative Agent receives a refund in respect of any
Indemnified Tax paid by the Borrower, or as to which it has been indemnified by
the Borrower, which refund in the good faith judgment of such Lender is
allocable to such payment made pursuant to this Section, it shall promptly
notify the Borrower of such refund and shall, within 20 days of receipt, repay
such refund to the Borrower (together with any interest with respect thereto
received from the relevant taxing authority).  In any event, each Lender shall
have the right to arrange its tax affairs as it, in its sole discretion, deems
most advantageous to it and nothing shall require a Lender to disclose its tax
returns or other confidential fiscal or tax information to the Borrower.

     SECTION 2.17.  Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
                    ----------------------------------------------------------- 

          (a) The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest, fees or under Sections 2.14, 2.15 or
                                                         -------------  ----   
2.16, or otherwise) prior to 1:00 p.m., New York City time, on the date when
- ----                                                                        
due, in immediately available funds, without set-off or counterclaim.  Subject
to the provisions of the Securities Accounts Agreement, all such payments shall
be made to the Administrative Agent at its offices at 31 West 52nd Street, New
York, New York, 10019 except that payments pursuant to Sections 2.14, 2.15, 2.16
                                                       -------------  ----  ----
and 9.03 shall be made directly to the Persons entitled thereto.  The
    ----                                                             
Administrative Agent shall distribute any such payments (including payments
received pursuant to the provisions of the Securities Accounts Agreement)
received by it for the account of any other Person to the appropriate recipient
promptly following receipt thereof.  Except as set forth herein, if any payment
hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and, in the case of any
payment accruing interest, interest thereon shall be payable for the period of
such extension.  All payments hereunder shall be made in dollars.

          (b) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied, subject to the provisions
of the Securities Accounts Agreement, (i) first, to pay interest and fees then
due hereunder, ratably among the parties entitled thereto in accordance with the
amounts of interest and fees then due to such parties, and (ii) second, to pay
principal then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value) a
participation in the Loans of the other Lenders to the extent necessary so that
the benefit of all such payments shall 

                                       53
<PAGE>
 
be shared by the Lenders ratably in accordance with the aggregate amount of
principal of and accrued interest on their respective Loans; provided that (i)
                                                             -------- 
if any such participation is purchased and all or any portion of the payment
giving rise thereto is recovered, such participation shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans to any assignee
or participant, other than to the Borrower or any Subsidiary or other Affiliate
thereof (as to which the provisions of this paragraph shall apply).

          (d) Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders hereunder that the Borrower will not make
such payment, the Administrative Agent may assume that the Borrower has made
such payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders the amount due.  In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally
agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the Federal Funds Effective Rate for 3
days and at the Alternate Base Rate thereafter.

          (e) If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.05(b) or 2.17(d), then the Administrative Agent may,
                  ---------------    -------                                    
in its discretion (notwithstanding any contrary provision hereof), apply any
amounts thereafter received by the Administrative Agent for the account of such
Lender to satisfy such Lender's obligations under such Sections until all such
unsatisfied obligations are fully paid.

     SECTION 2.18.  Mitigation Obligations; Replacement of Lenders.
                    ---------------------------------------------- 

          (a)  If (1) any Lender requests compensation under Section 2.14, (2)
                                                             ------------     
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.16,
                                                                 ------------ 
or (3) on or after the date of this Agreement any change in any applicable law
or in the interpretation or application thereof shall make it unlawful for any
Lender to make or maintain Eurodollar Loans as contemplated by this Agreement,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.14 or 2.16, as the case may be,
                                      ------------    ----                     
in the future, (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender and (iii) if
applicable, would render lawful the making of Eurodollar Loans by such Lender as
contemplated by this Agreement.

          (b) If (1) any Lender requests compensation under Section 2.14 which
                                                            ------------      
is not being requested by the Lenders generally, (2) the Borrower is required to
pay any additional amount to any Lender or any Governmental Authority for the
account of any Lender pursuant to 

                                       54
<PAGE>
 
Section 2.16, (3) on or after the date of this Agreement any change in any
- ------------                                  
applicable law or in the interpretation or application thereof shall make it
unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by
this Agreement or (4) any Lender becomes a Defaulting Lender, then the Borrower
may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, so long as no Default shall have occurred and be
continuing, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 9.04), all
                                                             -------------
its interests, rights and obligations under this Agreement to an assignee that
shall assume such obligations (which assignee may be another Lender, if another
Lender accepts such assignment); provided that (i) the Borrower shall have
                                 --------             
received the prior written consent of the Administrative Agent, which consent
shall not unreasonably be withheld or delayed, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans,
accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Section 2.14 or payments required to be made pursuant to
                   ------------                     
Section 2.16, such assignment will result in a reduction in such compensation or
- ------------                                            
payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment
and delegation cease to apply.

          (c) If a Lender changes its applicable lending office (other than
pursuant to paragraph (d) below) and the effect of such change, as of the date
of such change, would be to cause the Borrower to become obligated to pay any
additional amount under Section 2.14 or 2.16, the Borrower shall not be
                        ------------    ----                           
obligated to pay such additional amount.

          (d) If a condition or an event occurs which would, or would upon the
passage of time or giving of notice, result in the payment of any additional
amount to any Lender by the Borrower pursuant to Section 2.14 or 2.16, such
                                                 ------------    ----      
Lender shall promptly notify the Borrower and the Administrative Agent and shall
take such steps as may reasonably be available to it to mitigate the effects of
such condition or event (which shall include efforts to rebook the Loans held by
such Lender at another lending office, or through another branch or an
affiliate, of such Lender); provided that such Lender shall not be required to
                            --------                                          
take any step that, in its reasonable judgment, would be materially
disadvantageous to its business or operations or would require it to incur
additional costs (unless the Borrower agrees to fund such costs in a manner
satisfactory to such Lender).

fund its portion of the Loans then being requested and (2) this condition
precedent shall not apply in the case of any other Credit Extension.

          (d) No Force Majeure.  No event of force majeure (as such term is
              ----------------

                               -------------
with such Schedule (as such Schedule may be amended or supplemented in
accordance with Section 3.08) to be obtained (and, in the case of St. Croix
                ------------                         
Governmental Actions that do not by their terms permit the Borrower or the U.S.
Subsidiary to enjoy the benefits thereof, effectively conveyed or leased to the
Borrower or the U.S. Subsidiary by the St. Croix Affiliate, as applicable) on or
prior to the date of such Credit Extension shall have been duly obtained (and,
in the case of St. Croix Governmental Actions that do not by their terms permit
the Borrower or the U.S. Subsidiary to enjoy the benefits thereof, effectively
conveyed or leased to the Borrower or the U.S. Subsidiary by the St. Croix
Affiliate, as applicable), except for those Governmental Actions specifically
described in such certificate (the "Delinquent Governmental Actions") which the

Borrower, a Subsidiary, the St. Croix Affiliate or a System Contractor failed to

terms permit the Borrower or the U.S. Subsidiary to enjoy the benefits thereof,
the St. Croix Affiliate failed to effectively convey or lease to the Borrower or
the U.S. Subsidiary, as applicable) by the date of such Credit Extension,
provided that such failure on the date of such Credit Extension could not
- --------                     
reasonably be expected to have a Material Adverse Effect and (ii) nothing shall
have come to the attention of the Administrative Agent or the Borrower (and the
Borrower shall so certify to such effect) indicating that the St. Croix Corridor
License will not be obtained or will not either by its terms permit the Borrower
or the U.S. Subsidiary to enjoy the benefits thereof or be effectively conveyed
or leased by the St. Croix Affiliate to the Borrower or the U.S. Subsidiary by
the date set forth in Schedule 3.08, unless, based upon the date that the St.
                      -------------     
Croix Corridor License is then anticipated to be obtained or, if the St. Croix
Corridor License does not by its terms permit the Borrower or the U.S.
Subsidiary to enjoy the benefits thereof, the date on which the St. Croix
Affiliate will be able to effectively convey or lease the St. Croix Corridor
License to the Borrower or the U.S. Subsidiary, such delay would not, in the
opinion of the Lead Agents, reasonably be expected to have a Material Adverse
Effect.

          (f) Landing Licenses.  Unless such Credit Extension consists solely of
              ----------------

is required in accordance with such Schedule to have been satisfied on or prior
to the date of such Credit Extension shall have been duly satisfied or, with
respect to any such Milestone which has not been so satisfied by such date, such
certificate shall set forth the details associated with any such delay.  If any
Milestone with respect to a Landing License shall not have been satisfied by the

                    ------------------- 
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to

the exercise of any other right or power. The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement, any other Loan Document or any Consent or
consent to any departure by the Borrower or any Subsidiary therefrom shall in
any event be effective unless the same shall be permitted by paragraph (b) of
this Section, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the
generality of the foregoing, the making of a Loan shall not be construed as a
waiver of any Default, regardless of whether the Administrative Agent or any
Lender may have had notice or knowledge of such Default at the time.

Agent with the consent of the Majority Lenders (unless expressly provided
otherwise in this Agreement); provided that no such agreement shall (i) increase

or reduce any fees payable hereunder, without the written consent of each Lender
affected thereby, (iii) postpone the scheduled date of payment of the principal
amount of any Loan, or any interest thereon, or any fees payable hereunder, or

scheduled date of expiration of any Commitment, without the written consent of
each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner

of Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder or (vii) release all or
substantially all of the Collateral (other than in accordance with the terms of
the Security Documents) or release any guarantor from its obligations under a
guaranty (other than in accordance with the provisions thereof), without the
written consent of each Lender; provided further that no such agreement shall
                                -------- -------

Agent hereunder without the prior written consent of the Administrative Agent.

     SECTION 9.03.  Expenses; Indemnity; Damage Waiver. (a) The Borrower shall

with the ongoing consideration of legal matters relevant to any of the
foregoing, including the ongoing compliance with this Agreement and the security

expenses of the Consultants in connection with the preparation of their reports
and the ongoing fees and expenses of the Independent Engineer, (iv) any expenses
the Borrower or any Subsidiary specifically agrees to pay pursuant to any

incurred by the Agents or any Lender, but only in connection with the
enforcement or protection of its rights or remedies in connection with this
Agreement and the Loan Documents, including its rights under this Section, or in
connection with the Loans made hereunder, including in connection with any
workout, restructuring or negotiations in respect thereof, provided that with
                                                           -------- 
respect to legal fees, the Borrower shall be responsible to pay only the
reasonable fees and expenses of one or more counsel selected by the
Administrative Agent for the benefit of itself, the Lead Agents, the other
Agents, the Lead Agents, the Lenders and their respective Affiliates. Other than

continuing) the Administrative Agent agrees to confer with the Borrower in
advance of the incurrence of any such expenses.

          (b) The Borrower shall indemnify the Administrative Agent, the Lead
Agents and each Lender, and each Related Party of any of the foregoing Persons
(each such Person being called an "Indemnitee") against, and shall hold each
                                   ----------                               
Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses (subject, in the case of ordinary expenses, to the provisions
of Section 9.03(a)), including the fees, charges and disbursements of any
   ---------------                                                       
counsel for any Indemnitee, incurred by or asserted against any Indemnitee
arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement or any agreement or instrument contemplated hereby,
the performance by the parties hereto of their respective obligations hereunder
or the consummation of the transactions contemplated hereby, (ii) any presence
or release of Hazardous Materials on or from any property owned or operated by
the Borrower or any Subsidiary, or any Environmental Liability related in any
way to the Borrower or any Subsidiary, (iii) the use by the Lead Agents of the
syndication materials (whether or not such materials were provided by the
Borrower) or (iv) any actual or prospective claim, litigation, investigation or
proceeding relating to any of the foregoing, whether based on contract, tort or
any other theory and regardless of whether any Indemnitee is a party thereto;
provided that such indemnity shall not, as to any Indemnitee, be available to
- --------                                                                     
the extent that such losses, claims, damages, liabilities or related expenses
resulted from the gross negligence or willful misconduct of such Indemnitee or
relate to a claim brought by an assignee or Participant against the Lender
making such assignment or participation.  If for any reason the foregoing
indemnification is unavailable to any Indemnitee or is insufficient to hold it
harmless, then the Borrower shall contribute to the amount paid or payable by
such Indemnitee as a result of such loss, claim, damage, liability or related
expense in such proportion as is appropriate to reflect the relative economic
interests of the Borrower and the Shareholders on the one hand and such
Indemnitee on the other hand in the transactions contemplated hereby as well as
the relative fault of the Borrower and such Indemnitee with respect to such
loss, claim, damage or liability and any other relevant equitable
considerations.

          (c) Each Indemnitee claiming any right to indemnity under paragraph
(b) of this Section by reason of the institution of any action against such
Indemnitee shall notify the Borrower thereof and shall consult with the Borrower
from time to time in connection with the defense of such action.  In case any
such action shall be brought against such Indemnitee, the Borrower shall be
entitled, at its expense, to assume the defense thereof or to participate in
such action with counsel of its choice (which counsel shall be reasonably
satisfactory to such Indemnitee); provided that the Borrower may not settle any
                                  --------                                     
such action without the prior written consent of such Indemnitee (such consent
not to be unreasonably withheld or delayed) and the Borrower shall not be
entitled to assume the defense thereof if (i) such Indemnitee reasonably
determines, on the advice of counsel, that representation of both the Borrower
and such Indemnitee by the Borrower's counsel would present such counsel with a
conflict of interest, (ii) the defendants in, or targets of, any such action
include both such Indemnitee and the Borrower, and such Indemnitee shall have
reasonably concluded, on advice of counsel, that there may be legal defenses
available to it which are significantly different from those available to the
Borrower, (iii) the Borrower shall not have employed counsel satisfactory to
such Indemnitee to represent such Indemnitee within a reasonable time after
notice of the institution of any such action or (iv) such Indemnitee is faced
with potential criminal liability.

     SECTION 9.04.  Successors and Assigns; Consent and Agreement. (a) The
                    --------------------------------------------- 
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns permitted hereby,
except that the Borrower may not assign or otherwise transfer any of its rights
or obligations hereunder without the prior written consent of each Lender (and
any attempted assignment or transfer by the Borrower without such consent shall
be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Agent Related Parties and Related Parties of the
Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement. All Lenders now or hereafter parties to this Agreement hereby
agree to be bound by the terms of the Contractor Consents to the same extent as
the Administrative Agent.

          (b) Any Lender may assign to one or more assignees (other than to the
Borrower, any Subsidiary or any of its Affiliates) all or a portion of its
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans at the time owing to it) and the other Loan Documents;
                                                                               
provided that (i) except in the case of an assignment to a Lender or an
- --------                                                               
assignment solely of a Lender's rights or benefits under the Loan Documents to
an Affiliate of any Lender or, with respect to any Lender that is a fund that
invests in bank loans, to an Approved Fund, no such assignment shall be
permitted without the prior written consent of each of the Borrower and the
Administrative Agent (which shall not be unreasonably withheld), (ii) except in
the case of an assignment to a Lender or an Affiliate of a Lender or, with
respect to any Lender that is a fund that invests in bank loans, to an Approved
Fund, or an assignment of the entire remaining amount of the assigning Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Administrative Agent) shall not
be less than $5,000,000 unless each of the Borrower and the Administrative Agent
otherwise consent (which consent shall not be unreasonably withheld), (iii) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender's rights and obligations under this Agreement, (iv) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Acceptance for its acceptance and recording in the Register,
together with a processing and recordation fee of $3,500 (which shall be paid by
the assignor and/or assignee but not the Borrower), (v) the assignee shall not,
as of the effective date of such assignment, be entitled to receive any greater
payment under Section 2.14 or 2.16 than the assigning Lender shall be entitled
              ------------    ----                                            
to receive with respect to the obligations sold and (vi) notwithstanding
anything to the contrary in this Section 9.04(b), unless an Event of Default
                                 ---------------                            
shall have occurred and be continuing, the Lead Agents, collectively, shall
retain a combination of Loan Commitments and principal amount of Loans in an
amount not less than the lesser of (x) $20,000,000 in the aggregate and (y) 10%
(or such other percentage as may be agreed upon by the Lead Agents and the
Borrower) of the total amount of Loan Commitments and Loans than outstanding
unless the Borrower shall otherwise consent (such consent not to be unreasonably
withheld), provided that all or any portion of such Loan Commitments and the
           --------                                                         
Loans made thereunder may be held by the Lead Agents as lenders of record only.
Upon acceptance and recording pursuant to paragraph (d) of this Section, from
and after the effective date specified in each Assignment and Acceptance, the
assignee thereunder 

                                      106
<PAGE>
 
shall be a party hereto and, to the extent of the interest assigned by such
Assignment and Acceptance, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto). Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this paragraph shall be treated for purposes of this Agreement as a
sale by such Lender of a participation in such rights and obligations in
accordance with paragraph (e) of this Section.

          (c) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders and the registered
owner(s) of any obligation evidenced by a Note, and the Commitment of, and
principal amount of the Loans owing to, each Lender pursuant to the terms hereof
from time to time (the "Register").  The Notes and the obligations evidenced
                        --------                                            
thereby may be assigned or otherwise transferred in whole or in part only by
registration in the Register and the Note evidencing the same shall be
registered on the Register only upon surrender for registration of assignment or
transfer of the Note evidencing such obligation, duly endorsed by (or
accompanied by a written instrument of assignment or transfer duly executed by)
the registered owner thereof, and thereupon one or more new Note(s) in the same
aggregate principal amount shall be issued to the designated assignee(s) and the
old Notes shall be returned by the Administrative Agent to the Borrower marked
"canceled."  No assignment of any Note or obligation evidenced thereby shall be
effective unless it has been recorded in the Register as provided in this
Section 9.04(c).  The entries in the Register shall be conclusive, and the
- ---------------                                                           
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary.

          (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the processing and recordation
fee referred to in paragraph (b) of this Section, evidence of such assignee's
exemption from withholding Taxes and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept
such Assignment and Acceptance and record the information contained therein in
the Register.  No assignment shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this paragraph.

          (e) Any Lender may, without the consent of the Borrower, the
Administrative Agent, or the Lead Agents, sell participations to one or more
banks or other entities (a "Participant") in all or a portion of such Lender's
                            -----------                                       
rights and obligations under this Agreement (including all or a portion of its
Commitment and the Loans owing to it); provided that (i) such Lender's
                                       --------                       
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent, the Lead
Agents and the other Lenders shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations 

                                      107
<PAGE>
 
under this Agreement. Any agreement or instrument pursuant to which a Lender
sells such a participation shall provide that such Lender shall retain the sole
right to enforce this Agreement and to approve any amendment, modification or
waiver of any provision of this Agreement. Subject to paragraph (f) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 2.14, 2.15 and 2.16 to the same extent as if it were a 
            -------------  ----     ----   
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section.

          (f) A Participant shall not be entitled to receive any greater payment
under Section 2.14, 2.15 or 2.16 than the applicable Lender would have been
      ------------  ----    ----                                           
entitled to receive with respect to the participation sold to such Participant,
and any such payment received by a Participant shall be in lieu of, and not
duplicative of, the comparable payment that would have been due to such
applicable Lender.  A Participant shall not be entitled to the benefits of
Section 2.16 unless the Borrower is notified of the participation sold to such
- ------------                                                                  
Participant and such Participant agrees, for the benefit of the Borrower, to
comply with the provisions of Section 2.16(e) as though it were a Lender.
                              ---------------                            

          (g) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of
such Lender, including any such pledge or assignment to a Federal Reserve Bank,
and this Section shall not apply to any such pledge or assignment of a security
interest; provided that no such pledge or assignment of a security interest
          --------                                                         
shall release a Lender from any of its obligations hereunder or substitute any
such assignee for such Lender as a party hereto.

     SECTION 9.05.  Limited Recourse. There shall be full recourse to the
                    ---------------- 
Borrower and each Subsidiary for the liabilities of the Borrower and the
Subsidiaries under this Agreement and the other Loan Documents, but in no event
shall any holder of any equity interest in the Borrower (or any officer or
director of such holder or any officer or director of the Borrower or any
Subsidiary, in its capacity as such) be personally liable or obligated for such
liabilities of the Borrower and the Subsidiaries.

     SECTION 9.06.  Survival. All covenants, agreements, representations and
                    -------- 
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, and shall continue in full force and effect as long as the principal of
or any accrued interest on any Loan or any fee or any other amount payable under
this Agreement is outstanding and unpaid and so long as the Commitments have not
expired or terminated. The provisions of Sections 2.14, 2.15, 2.16 and 9.03 and
                                         -------------  ----  ----     ----
Article VIII shall survive and remain in full force and effect regardless of the
- ------------                         
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Commitments or the termination of
this Agreement or any provision hereof.

     SECTION 9.07.  Counterparts; Integration; Effectiveness. This Agreement may
                    ---------------------------------------- 
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single 

                                      108
<PAGE>
 
contract. This Agreement and any agreements referred to herein and any separate
letter agreements with respect to fees payable to an Agent and/or Agent Related
Person constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been
- ------------      
executed by the Borrower and the Administrative Agent and when the
Administrative Agent shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and, subject to and in accordance with Section 9.04, their respective successors
                                       ------------  
and assigns. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be as effective as delivery of a manually executed
counterpart of this Agreement.

     SECTION 9.08.  Severability. Any provision of this Agreement held to be
                    ------------ 
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

     SECTION 9.09.  Right of Setoff. If an Event of Default shall have occurred
                    ---------------

deposits (general or special, time or demand, provisional or final) at any time
held (other than deposits in the Accounts) and other indebtedness at any time
owing by such Lender to or for the credit or the account of the Borrower against
any of and all the obligations of the Borrower now or hereafter existing under
this Agreement held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement and although such obligations
may be unmatured. The rights of each Lender under this Section are in addition
to other rights and remedies (including other rights of setoff) which such
Lender may have.

          (b) The Borrower hereby 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

parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any 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.  Each of
the parties hereto 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

          (c) The Borrower hereby irrevocably and unconditionally 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 Agreement in any court referred to in
paragraph (b) of this Section.  Each of the parties hereto 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.

          (d) Each party to this agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01.  Nothing in this
                                              ------------

receiving service of process in any jurisdiction.

     SECTION 9.11.  WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
                    -------------------- 
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

     SECTION 9.12.  Headings. Article and Section headings and the Table of

     SECTION 9.14.  Confidentiality. Each of the Administrative Agent, the Lead
                    --------------- 
Agents, any other Agents and the Lenders agrees to maintain the confidentiality
of the Information (as defined below), except that Information may be disclosed
(a) to its and its Affiliates' directors, officers, employees and agents,
including accountants, legal counsel and other advisors (it being understood
that the Persons to whom such disclosure is made will be informed of the
confidential nature of such Information and instructed to keep such Information
confidential), (b) to the extent requested by any governmental or regulatory
authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Agreement,
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section, to any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations

unreasonably withheld or delayed), (h) to the extent such Information (x)
becomes publicly available other than as a result of a breach of this Section or
(y) becomes 

                                      110
<PAGE>
 
available to the Administrative Agent, the Lead Agents or any Lender on a
nonconfidential basis from a source other than the Borrower or (i) to any direct
or indirect contractual counterparties in swap agreements or such contractual
counterparties' professional advisors, provided that such contractual
counterparty or professional advisor to such contractual counterparty agrees in
writing to keep such information confidential to the same extent required of the
Lenders hereunder. For the purposes of this Section, "Information" means all
information received from or on behalf of the Borrower relating to the 
- ------------                                                                  
Borrower, any Subsidiary, its business or the System, other than any such
information that is available to the Administrative Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower; provided that,
                                                          --------      
in the case of information received from the Borrower after the date hereof,
such information is clearly identified at the time of delivery as confidential.
Any Person required to maintain the confidentiality of Information as provided
in this Section shall be considered to have complied with its obligation to do
so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

     SECTION 9.15.  Right of Quiet Enjoyment. The Administrative Agent and each
                    ------------------------ 
Lender agrees, for the benefit of each Person not an Affiliate of the Borrower
now or hereafter acquiring rights from the Borrower or any Subsidiary in respect
of any Capacity pursuant to a Capacity Sales Agreement, indefeasible right of
use agreement, or otherwise in accordance with Section 6.23 (a "Capacity
                                               ------------     --------
Purchaser"), that, notwithstanding any other provision hereof or any other Loan
- ----------                                  
Document, so long as no event has occurred and is continuing under such
agreement which entitles the Borrower or a Subsidiary to suspend service to such
Capacity Purchaser, the Administrative Agent and such Lender will not take or
cause to be taken any action to interfere with such Capacity Purchaser's right
to quiet enjoyment. The Administrative Agent agrees to provide, and the Lenders
hereby authorize it to provide, at the written request of the Borrower, a
written confirmation of the foregoing for the benefit of such Capacity
Purchasers.

     SECTION 9.16.  Judgment Currency. If, for the purposes of obtaining
                    ----------------- 
judgment in any court, it is necessary to convert a sum due hereunder in one
currency into another currency, the parties hereto agree, to the fullest extent
permitted by law, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase the former currency with such other currency on the Business Day
preceding that on which final judgment is given. The obligation of the Borrower
in respect of any sum due from it to the Administrative Agent hereunder shall,
notwithstanding any judgment in a currency other than the currency in which such
sum shall have been due, be discharged only to the extent that, on the Business
Day following receipt thereof by the Administrative Agent, the Administrative
Agent may in accordance with normal banking procedures purchase the currency in
which sum was due with such other currency in which judgment was rendered; if
the currency so purchased exceeds the sum originally due to the Administrative
Agent in the former currency, the Administrative Agent agrees to remit to the
Borrower such excess.

Dear Sirs,


          RE:  GLOBAL CROSSING HOLDINGS LTD. (THE "COMPANY")
          --------------------------------------------------



     We have acted as legal counsel in Bermuda to the Company in connection with
the Exchange Offer to be made pursuant to the Exchange Offer Registration
Statement and pursuant to which the Company shall offer to the Holders of all
outstanding Transfer Restricted Securities held by such Holders, the opportunity
to exchange all such outstanding Transfer Restricted Securities for New
Preferred Stock, and where appropriate, for New Exchange Notes.

     Unless otherwise defined in this opinion or the Schedules to it,
capitalised terms have the meanings assigned to them in the Registration Rights
Agreement.

     For the purposes of this opinion we have examined and relied upon the
documents listed (which, in some cases, are also defined) in the Schedule to
this opinion (the "Documents").


ASSUMPTIONS

     In stating our opinion we have assumed:-


     (a) the authenticity, accuracy and completeness of all Documents

     originals and the conformity to authentic original Documents of all
     Documents submitted to us as certified, conformed, notarised or photostatic
     copies;


     (b) the genuineness of all signatures on the Documents;

     Documents (other than the Company);



     (d) that any factual statements made in any of the Documents are true,
     accurate and complete;

     obligations of each of the parties thereto, other than the Company, under
     the laws of its jurisdiction of incorporation or its jurisdiction of
     formation;



     (f) that the Operative Documents have been validly authorised, executed and
     delivered by each of the parties thereto, other than the Company, and the
     performance thereof is within the capacity and powers of each such party
     thereto, and that each such party to which the Company purportedly
     delivered the Operative Documents has actually received and accepted
     delivery of such Operative Documents;



     (g) that the Operative Documents will effect, and will constitute legal,
     valid and binding obligations of each of the parties thereto, enforceable
     in accordance with their terms, under the laws of the State of New York by
     which they are governed;



     (h) that the Operative Documents are in the proper legal form to be

     and in accordance with the laws of the State of New York;



     (i) that there are no provisions of the laws or regulations of any
     jurisdiction other than Bermuda which would be contravened by the execution
     or delivery of the Operative Documents or which would have any implication

     obligation under, or action to be taken under, the Operative Documents and
     the Bye-laws of the Company is required to be performed or taken in any
     jurisdiction outside Bermuda, the performance of such obligation or the
     taking of such action will constitute a valid and binding obligation of
     each of the parties thereto under the laws of that jurisdiction and will
     not be illegal by virtue of the laws of that jurisdiction;



     (j) that the Resolutions are in full force and effect and have not been
     rescinded, either in whole or in part and accurately record the resolutions
     passed by the Board of Directors of the Company, as the case may be, at

     were present and voting throughout and accurately record the resolutions
     adopted by the Shareholder of the Company;
<PAGE>
 
                                       3

     (k) that the Company has entered into its obligations under the Operative
     Documents in good faith for the purpose of carrying on its business and
     that, at the time it did so, there were reasonable grounds for believing
     that the transactions contemplated by the Operative Documents and by the
     amendment of the Bye-laws of the Company would benefit the Company; and

     (l) that when executed, or in the case of the Exchange Offer Registration
     Statement when filed, any document presented to us in draft will not differ
     in any material way from the draft which we have examined.



OPINION
- -------


     Based upon and subject to the foregoing and subject to the reservations set
out below and to any matters not disclosed to us, we are of the opinion that:-



(1)  When issued in accordance with the terms of the Bye-laws of the Company,
     and the Exchange Offer Registration Statement, the New Preferred Stock to
     be issued as part of the Exchange Offer will be duly authorised, validly
     issued, fully paid and non-assessable shares of the Company.

(2)  The New Exchange Notes have been duly authorised for issuance and, upon due
     execution and delivery of the Indenture, in accordance with the authority
     given in the Resolutions, and when issued in accordance with the Indenture
     and the Exchange Offer Registration Statement, the New Exchange Notes will
     constitute valid and binding obligations of the Company enforceable against
     the Company in accordance with their terms.

(3)  A final and conclusive judgment of the United States Federal or New York
     State Courts based upon the Securities, the Bye-laws of the Company or the
     Operative Documents under which a sum of money is payable (not being a sum
     payable in respect of taxes or other charges of a like nature, in respect
     of a fine or other penalty, or in respect of multiple damages as defined in
     The Protection of Trading Interests Act 1981) may be the subject of
     enforcement proceedings in the Supreme Court of Bermuda without re-
     examination of the merits of the case under the common law doctrine of
     obligation by action on the debt evidenced by the foreign court's judgment.
     On general principles, we would expect such proceedings to be successful
     provided that the court which gave the judgment was competent to hear the
     action in accordance with private international law principles as applied
     in Bermuda and the judgment is not contrary to public policy in Bermuda,
     has not been obtained by fraud or in proceedings contrary to natural
     justice and is not based on an error in Bermuda law.

     Enforcement of such a judgment against assets in Bermuda may involve the
conversion of the judgment debt into Bermuda dollars, but the Bermuda Monetary
<PAGE>
 
                                       4

Authority has indicated that its present policy is to give the consents
necessary to enable recovery in the currency of the obligation.



RESERVATIONS
- ------------


     We have the following reservations:-

(a)  The term "enforceable" as used in this opinion means that the obligations
     assumed by the relevant party under the Bye-laws of the Company and the
     Operative Documents are of a type which the courts of Bermuda enforce.  It
     does not mean that those obligations will necessarily be enforced in all
     circumstances in accordance with their terms, because of the matters
     referred to in reservation (b).

(b)  We express no opinion as to the availability of equitable remedies such as
     specific performance or injunctive relief, or as to any matters which are
     within the discretion of the courts of Bermuda in respect of any
     obligations of the Company as set out in the Operative Documents and in the
     Bye-laws of the Company.  Further, we express no opinion as to the validity
     or binding effect of any waiver of or obligation to waive either any
     provision of law (whether substantive or procedural) or any right or
     remedy.


(c)  Enforcement of the obligations of the Company under the Bye-laws of the
     Company and the Operative Documents may be limited or affected by
     applicable laws from time to time in effect relating to bankruptcy,
     insolvency or liquidation or any other laws or other legal procedures
     affecting generally the enforcement of creditors' rights.



(d)  Enforcement of the obligations of the Company may be the subject of a
     statutory limitation of the time within which such proceedings may be
     brought.


(e)  We express no opinion as to any law other than Bermuda law and none of the
     opinions expressed herein relates to compliance with or matters governed by
     the laws of any jurisdiction except Bermuda.  This opinion is limited to
     Bermuda law as applied by the Courts of Bermuda at the date hereof.

(f)  Where an obligation is to be performed in a jurisdiction other than
     Bermuda, the courts of Bermuda may refuse to enforce it to the extent that
     such performance would be illegal under the laws of, or contrary to public
     policy of, such other jurisdiction.

(g)  We express no opinion as to the validity, binding effect or enforceability
     of any provision incorporated into the Bye-laws of the Company or any of
     the Operative 
<PAGE>
 
                                       5

     Documents by reference to a law other than that of Bermuda, or as to the
     availability in Bermuda of remedies which are available in other
     jurisdictions.



(h)  We express no opinion as to the validity or binding effect of any provision
     of the Bye-laws of the Company or of the Operative Documents which provides
     for the severance of illegal, invalid or unenforceable provisions.

(i)  A Bermuda court may refuse to give effect to any provisions of the
     Operative Documents and the Bye-laws of the Company in respect of costs of
     unsuccessful litigation brought before the Bermuda court or where that
     court has itself made an order for costs.


(j)  Any reference in this opinion to shares being "non-assessable" shall mean,
     in relation to fully-paid shares of the company and subject to any contrary
     provision in any agreement in writing between such company and the holder
     of shares, that: no shareholder shall be obliged to contribute further
     amounts to the capital of the company, either in order to complete payment
     for their shares, to satisfy claims of creditors of the company, or
     otherwise; and no shareholder shall be bound by an alteration of the
     Memorandum of Association or Bye-laws of the company after the date on
     which he became a shareholder, if and so far as the alteration requires him
     to take, or subscribe for additional shares, or in any way increases his
     liability to contribute to the share capital of, or otherwise to pay money
     to, the company.

Global Crossing Holdings Ltd.

Hamilton HM12, Bermuda

Ladies and Gentlemen:

        We have acted as U.S. counsel for Global Crossing Holdings Ltd., a
corporation organized under the laws of Bermuda (the "Company"), in connection
with the Registration Statement on Form S-4 (the "Registration Statement") filed
by the Company with the Securities and Exchange Commission (the "Commission")
under the Securities Act of 1933, as amended (the "Securities Act"), relating to
the issuance by the Company of 5,000,000 shares of 10 1/2% Senior Exchangeable
Preferred Stock due 2008, no par value (the "Exchange Preferred Stock").  Shares
of the Exchange Preferred Stock are to be offered by the Company in exchange for
(the "Exchange Offer") its outstanding 5,000,000 shares of 10 1/2% Senior
Exchangeable Preferred Stock due 2008, no par value (the "Old Preferred Stock").
Pursuant to the Registration Statement, the Company has also registered 10 1/2%
Senior Subordinated Exchange Notes due 2008 (the "Exchange Notes"), which, at
the Company's option, may be issued in exchange for the Old Preferred Stock or
the Exchange Preferred Stock subject to certain conditions.  The Exchange Notes
would be issued under an 
<PAGE>
 
Global Crossing Holdings Ltd.       -2-

indenture to be executed at the time of issuance between the Company and a
trustee for holders of the Exchange Notes (the "Indenture").

        We have examined the Registration Statement and the Indenture, a form of
which has been filed with the Commission as an exhibit to the Registration
Statement.  In addition, we have examined, and have relied as to matters of fact
upon, the originals or copies, certified or otherwise identified to our
satisfaction, of such corporate records, agreements, documents and other
instruments and such certificates or comparable documents of public officials
and of officers and representatives of the Company, and have made such other and
further investigations, as we have deemed relevant and necessary as a basis for
the opinions hereinafter set forth.

        In such examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents.

        We have further assumed that, with respect to each of the parties to the
Indenture and the Exchange Notes, as the case may be, (i) such person was duly
incorporated or organized and is validly existing under the laws of the
jurisdiction in which it was incorporated or organized, (ii) such person has the
power and authority to execute the Indenture and the Exchange Notes, as the case
may be, to which it is a party and to take all actions contemplated to be taken
by it thereunder and (iii) such person has duly authorized, executed and
delivered the Indenture and the Exchange Notes, as the case may be, to which it
is a party in accordance with the charter or other organizational documents of
such person.
<PAGE>
 
Global Crossing Holdings Ltd.           -3-

        Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that when (1) the Indenture has
been duly qualified under the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act"), (2) the Board of Directors of the Company, a duly
constituted and acting committee thereof or duly authorized officers thereof
have taken all necessary corporate action to approve the issuance and terms of
the Exchange Notes and related matters, and (3) the Exchange Notes have been
duly executed, authenticated, issued and delivered in accordance with the
provisions of the Indenture, the Exchange Notes will constitute valid and
legally binding obligations of the Company enforceable against the Company in
accordance with their terms and entitled to the benefits of the Indenture.

        Our opinion set forth above is subject to (i) the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally, (ii) general
equitable principles (whether considered in a proceeding in equity or at law),
(iii) an implied covenant of good faith and fair dealing and (iv) the effects of
the possible judicial application of foreign laws or foreign governmental or
judicial action affecting creditors' rights.

        We are members of the Bar of the State of New York, and we do not
express any opinion herein concerning any law other than the laws of the State
of  New York and the federal laws of the United States.  Insofar as the opinions
set forth herein relate to issues governed by the laws of Bermuda, we have
assumed the correctness of the opinion of Appleby, Spurling & Kempe, which is
also filed as an exhibit to the Registration Statement.    
         
        We hereby consent to the use of this opinion as an exhibit to the
Registration

Statement and to the reference to our firm under the caption "Legal Matters" in

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the above-described aggregate
liquidation preference of the Company's 10 1/2% Senior Exchangeable Preferred
Stock (the "Old Preferred Stock") in exchange for a like aggregate liquidation
preference of the Company's 10 1/2% Senior Exchangeable Preferred Stock (the
"Exchange Preferred Stock"), shares of which have been registered under the
Securities Act of 1933, as amended (the "Securities Act") upon the terms and
subject to the conditions set forth in the Prospectus dated ___________, 1999
(as the same may be amended or supplemented from time to time, the
"Prospectus"), receipt of which is acknowledged, and in this Letter of
Transmittal (which, together with the Prospectus, constitute the "Exchange
Offer").

     Subject to, and effective upon, the acceptance for exchange of all or any
portion of the shares of Old Preferred Stock tendered herewith in accordance
with the terms and conditions of the Exchange Offer (including, if the Exchange
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the undersigned hereby exchanges, assigns and transfers to, or upon
the order of, the Company all right, title and interest in and to such shares of
Old Preferred Stock as are being tendered herewith. The undersigned hereby
irrevocably constitutes and appoints the Exchange Agent as its true and lawful
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company, in connection with the Exchange Offer) with
respect to the tendered shares of Old Preferred Stock, with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), subject only to the right of withdrawal described in
the Prospectus, to (i) deliver certificates for shares of Old Preferred Stock to
the Company together with all accompanying evidences of transfer and
authenticity to, or upon the order of, the Company, upon receipt by the Exchange
Agent, as the undersigned's agent, of the shares of Exchange Preferred Stock to
be issued in exchange for such shares of Preferred Stock, (ii) present
certificates for such shares of Old Preferred Stock for transfer, and to
transfer the shares of Old Preferred Stock on the books of the Company, and
(iii) receive for the account of the Company all benefits and otherwise exercise

accordance with the terms and conditions of the Exchange Offer.

     The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the shares of Old Preferred
Stock tendered hereby and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title to the tendered Old Preferred
Stock, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim. The undersigned also warrants that it will,
upon request, execute and deliver any additional documents deemed by the
Exchange Agent or the Company to be necessary or desirable to complete the
exchange, assignment and transfer of the tendered shares of Old Preferred Stock
or transfer ownership of shares of Old Preferred Stock on the account books

that acceptance of any and all validly tendered shares of Old Preferred Stock by
the Company and the issuance of Exchange Preferred Stock in exchange therefor
shall constitute

performance in full by the Company of its obligations under the Registration
Rights Agreement (as defined in the Prospectus) and that the Company shall have
no further obligations or liabilities thereunder. The undersigned will comply
with its obligations under the Registration Rights Agreement. The undersigned
has read and agrees to all terms of the Exchange Offer.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus. The undersigned recognizes that as a result of these conditions
(which may be waived, in whole or in part, by the Company), as more particularly
set forth in the Prospectus, the Company may not be required to exchange any of
the shares of Old Preferred Stock tendered hereby and, in such event, the shares
not exchanged will be returned (or, in the case of shares of Old Preferred Stock
tendered by book-entry transfer, such shares of Old Preferred Stock will be
credited to an account maintained at DTC), without expense to the tendering
holder promptly following the expiration or termination of the Exchange Offer.

     The undersigned understands that tenders of shares of Old Preferred Stock
pursuant to any one of the procedures described in the Prospectus and in the
instruction attached hereto will, upon the Company's acceptance for exchange of
such tendered shares of Old Preferred Stock, constitute a binding agreement
between the undersigned and the Company upon the terms and subject to the
conditions of the Exchange Offer. The undersigned recognizes that, under
circumstances set forth in the Prospectus, the Company may not be required to
accept for exchange any of the shares of Old Preferred Stock tendered hereby.

     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, the undersigned hereby directs that the shares of Exchange
Preferred Stock be issued in the name(s) of the undersigned or, in the case of a
book-entry transfer of shares of Old Preferred Stock, that such shares of
Exchange Preferred Stock be credited to the account indicated above maintained
at DTC. If applicable, substitute certificates representing shares of Old
Preferred Stock not exchanged or not accepted for exchange will be issued to the
undersigned or, in the case of book-entry transfer of shares of Old Preferred
Stock, will be credited to the account indicated above maintained at DTC.
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please deliver shares of Exchange Preferred Stock to the undersigned at the
address shown below the undersigned's signature.

     By tendering shares of Old Preferred Stock and executing this Letter of
Transmittal, the undersigned represents that Exchange Preferred Stock acquired
in the exchange will be obtained in the ordinary course of business of the
undersigned, that the undersigned has no arrangement or understanding with any
person to participate in a distribution (within the meaning of the Securities
Act) of such Exchange Preferred Stock, that the undersigned is not an
"affiliate" of the Company within the meaning of Rule 405 under the Act and that
if the undersigned or the person receiving such Exchange Preferred Stock,
whether or not such person is the undersigned, is not a broker-dealer, the
undersigned represents that it is not engaged in, and does not intend to engage
in, a distribution of Exchange Preferred Stock. If the undersigned or the person
receiving such Exchange Preferred Stock, whether or not such person is the
undersigned, is a broker-dealer that will receive Exchange Preferred Stock for
its own account in exchange for shares of Old Preferred Stock that were acquired
as a result of market-making activities or other trading activities, it
acknowledges that it will deliver a prospectus in connection with any resale of
such Exchange Preferred Stock; however, by so acknowledging

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
   PROCEDURES.
 
  Certificates for all physically delivered shares of Old Preferred Stock or
confirmation of any book-entry transfer to the Exchange Agent's or its agent's
account at a book-entry transfer facility of shares of Old Preferred Stock
tendered by book-entry transfer, as well as a properly completed and duly
executed copy of this Letter of Transmittal or facsimile thereof, and any other
documents required by this Letter of Transmittal, must be received by the
Exchange Agent at any of its addresses set forth herein on or prior to the
Expiration Date.
 
  Holders of shares of Old Preferred Stock may tender shares of Old Preferred
Stock by book-entry transfer by crediting the shares of Old Preferred Stock to
the Exchange Agent's account at the DTC in accordance with the DTC's Automated
Tender Offer Program ("ATOP") and by complying with applicable ATOP procedures
with respect to the Exchange Offer. DTC participants that are accepting the
Exchange Offer should transmit their acceptance to DTC, which will edit and
verify the acceptance and execute a book-entry delivery to the Exchange Agent's
account at DTC. DTC will then send a computer-generated message (an "Agent's
Message") to the Exchange Agent for its acceptance in which the holder of the
shares of Old Preferred Stock acknowledges and agrees to be bound by the terms
of, and makes the representations and warranties contained in, this Letter of
Transmittal, the DTC participant confirms on behalf of itself and the
beneficial owners of such shares of Old Preferred Stock all provisions of this
Letter of Transmittal (including any representations and warranties) applicable
to it and such beneficial owner as fully as if it had completed the information
required herein and executed and transmitted this Letter of Transmittal to the
Exchange Agent. Delivery of the Agent's Message by DTC will satisfy the terms
of the Exchange Offer as to execution and delivery of a Letter of Transmittal
by the participant identified in the Agent's Message. DTC participants may also
accept the Exchange Offer by submitting a Notice of Guaranteed Delivery through
ATOP.
 
  The method of delivery of this Letter of Transmittal, the shares of Old
Preferred Stock and any other required documents is at the election and risk of
the holder, and except as otherwise provided below, the delivery will be deemed
made only when actually received or confirmed by the Exchange Agent. If such
delivery is by mail, it is suggested that registered mail with return receipt
requested, properly insured, be used. In all cases sufficient time should be
allowed to permit timely delivery.
 
  Holders whose shares of Old Preferred Stock are not immediately available or
who cannot deliver their shares of Old Preferred Stock and all other required
documents to the Exchange Agent on or prior to the Expiration Date or comply
with book-entry transfer procedures on a timely basis must tender their shares
of Old Preferred Stock pursuant to the guaranteed delivery procedure set forth
in the Prospectus. Pursuant to such procedure: (i) such tender must be made by
or through an Eligible Institution (as defined in the Prospectus); (ii) on or
prior to the Expiration Date, the Exchange Agent must have received from such
Eligible Institution a letter, telegram or facsimile transmission (receipt
confirmed by telephone and an original delivered by guaranteed overnight
courier) setting forth the name and address of the tendering holder, the names
in which such shares of Old Preferred Stock are registered, and, if possible,
the certificate numbers of the shares of Old Preferred Stock to be tendered;
and (iii) all tendered shares of Old Preferred Stock (or a confirmation of any
book-entry transfer of such shares of Old Preferred Stock into the Exchange
Agent's account at a book-entry transfer facility or an Agent's Message in lieu
thereof) as well as this Letter of Transmittal and all other documents required
by this Letter of Transmittal, must be received by the Exchange Agent within
three New York Stock Exchange trading days after the date of execution of such
letter, telegram or facsimile transmission, all as provided in the Prospectus.
 
  No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance
of the shares of Old Preferred Stock for exchange.

<PAGE>
 
2. PARTIAL TENDERS; WITHDRAWALS.
 
  If less than the total number of any shares of Old Preferred Stock evidenced
by a submitted certificate is tendered, the tendering holder must fill in the
number of shares of Old Preferred Stock tendered in the box entitled "Number of
Shares Tendered." A newly issued certificate for the shares of Old Preferred
Stock submitted but not tendered will be sent to such holder as soon as
practicable after the Expiration Date. All shares of Old Preferred Stock
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise clearly indicated.
 
  If not yet accepted, a tender pursuant to the Exchange Offer may be withdrawn
prior to the Expiration Date. To be effective with respect to the tender of
shares of Old Preferred Stock, a notice of withdrawal must: (i) be received by
the Exchange Agent before the Company notifies the Exchange Agent that they
have accepted the tender of shares of Old Preferred Stock pursuant to the
Exchange Offer; (ii) specify the name of the shares of Old Preferred Stock;
(iii) contain a description of the Old Preferred Stock to be withdrawn, the
certificate numbers shown on the particular certificates evidencing such shares
of Old Preferred Stock and the number of shares of Old Preferred Stock
represented by such certificates; and (iv) be signed by the holder in the same
manner as the original signature on this Letter of Transmittal (including any
required signature guarantee). The Exchange Agent will return the properly
withdrawn shares of Preferred Stock promptly following receipt of notice of
withdrawal. If shares of Preferred Stock have been tendered pursuant to the
procedure for book-entry transfer, any notice of withdrawal must specify the
name and number of the account at the book-entry transfer facility to be
credited with the withdrawn shares of Preferred Stock or otherwise comply with
the book-entry transfer facility's procedures. All questions as to the validity
of notices of withdrawals, including time of receipt, will be determined by the
Company, and such determination will be final and binding on all parties.
 
3. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
   ENDORSEMENTS; GUARANTEE OF SIGNATURES.
 
  If this Letter of Transmittal is signed by the registered holder(s) of the
shares of Preferred Stock tendered hereby, the signature must correspond with
the name(s) as written on the face of the certificates without alteration,
enlargement or any change whatsoever.

  If any of the shares of Old Preferred Stock tendered hereby are owned of
record by two or more joint owners, all such owners must sign this Letter of
Transmittal.
 
  If a number of shares of Old Preferred Stock registered in different names
are tendered, it will be necessary to complete, sign and submit as many
separate copies of this Letter of Transmittal as there are different
registrations of shares of Old Preferred Stock.
 
  When this Letter of Transmittal is signed by the registered holder or holders
(which term, for the purposes described herein, shall include the book-entry
transfer facility whose name appears on a security listing as the owner of the
shares of Old Preferred Stock) of shares of Preferred Stock listed and tendered
hereby, no endorsements of certificates or separate written instruments of
transfer or exchange are required.
 
  If this Letter of Transmittal is signed by a person other than the registered
holder or holders of the shares of Old Preferred Stock listed, such shares of
Old Preferred Stock must be endorsed or accompanied by separate written
instruments of transfer or exchange in form satisfactory to the Company and
duly executed by the registered holder, in either case signed exactly as the
name or names of the registered holder or holders appear(s) on the shares of
Old Preferred Stock.
 
  If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or
others acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.
<PAGE>
 
   Endorsements on certificates or signatures on separate written instruments of
transfer or exchange required by this Instruction 3 must be guaranteed by an
Eligible Institution.
 
   Signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution, unless shares of Old Preferred Stock are tendered: (i) by a holder
who has not completed the Box entitled "Special Issuance Instructions" on this
Letter of Transmittal; or (ii) for the account of an Eligible Institution. In
the event that the signatures in this Letter of Transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by an eligible guarantor institution which is a member of The
Securities Transfer Agents medallion Program (STAMP). If shares of Old
Preferred Stock are registered in the name of a person other than the signer of
this Letter of Transmittal, the shares of Old Preferred Stock surrendered for
exchange must be endorsed by, or be accompanied by a written instrument or
instruments of transfer or exchange, in satisfactory form as determined by the
Company, in its sole discretion, duly executed by the registered holder with
the signature thereon guaranteed by an Eligible Institution.
 
4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.
 
   Tendering holders should indicate, as applicable, the name and address to
which the Exchange Preferred Stock or certificates for shares of Old Preferred
Stock not exchanged are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal. In the case of
issuance in a different name, the tax identification number of the person named
must also be indicated. Holders tendering shares of Old Preferred Stock by
book-entry transfer may request that shares of Old Preferred Stock not
exchanged be credited to such account maintained at the Book-Entry Transfer
Facility as such holder may designate.
 
5. TRANSFER TAXES.
 
   The Company shall pay all transfer taxes, if any, applicable to the transfer
and exchange of shares of Old Preferred Stock to it or its order pursuant to
the Exchange Offer. If a transfer tax is imposed for any reason other than the
transfer and exchange of shares of Old Preferred Stock to the Company or its
order pursuant to the Exchange Offer, the amount of any such transfer taxes
(whether imposed on the registered holder or any other person) will be payable
by the tendering holder. If satisfactory evidence of payment of such taxes or
exception therefrom is not submitted herewith the amount of such transfer taxes
will be billed directly to such tendering holder.
 
   Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the shares of Old Preferred Stock listed
in this Letter of Transmittal.
 
6. WAIVER OF CONDITIONS.
 
   The Company reserves the absolute right to waive, in whole or in part, either
of the conditions to the Exchange Offer set forth in the Prospectus.

correct taxpayer identification number ("TIN"), generally the holder's Social
Security or federal employer identification number, and certain other
information, on Substitute Form W-9, which is provided under "Important Tax

the certificate numbers of the shares of Old Preferred Stock to be tendered; and
(iii) all tendered shares of Old Preferred Stock (or a confirmation of any book-
entry transfer of such shares of Old Preferred Stock into the Exchange Agent's
account at a book-entry transfer facility or an Agent's Message in lieu thereof)
as well as this Letter of Transmittal and all other documents required by this
Letter of Transmittal, must be received by the Exchange Agent within three New
York Stock Exchange trading days after the date of execution of such letter,
telegram or facsimile transmission, all as provided in the Prospectus.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the shares of Old Preferred Stock for exchange.

2.   Partial Tenders; Withdrawals.

     If less than the total number of any shares of Old Preferred Stock
evidenced by a submitted certificate is tendered, the tendering holder must fill
in the number of shares of Old Preferred Stock tendered in the box entitled
"Number of Shares Tendered." A newly issued certificate for the shares of Old
Preferred Stock submitted but not tendered will be sent to such holder as soon
as practicable after the Expiration Date. All shares of Old Preferred Stock
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise clearly indicated.

     If not yet accepted, a tender pursuant to the Exchange Offer may be
withdrawn prior to the Expiration Date. To be effective with respect to the
tender of shares of Old Preferred Stock, a notice of withdrawal must: (i) be
received by the Exchange Agent before the Company notifies the Exchange Agent
that they have accepted the tender of shares of Old Preferred Stock pursuant to
the Exchange Offer; (ii) specify the name of the shares of Old Preferred Stock;
(iii) contain a description of the Old Preferred Stock to be withdrawn, the
certificate numbers shown on the particular certificates evidencing such shares
of Old Preferred Stock and the number of shares of Old Preferred Stock
represented by such certificates; and (iv) be signed by the holder in the same
manner as the original signature on this Letter of Transmittal (including any
required signature guarantee). The Exchange Agent will return the properly
withdrawn shares of Preferred Stock promptly following receipt of notice of
withdrawal. If shares of Preferred Stock have been tendered pursuant to the
procedure for book-entry transfer, any notice of withdrawal must specify the
name and number of the account at the book-entry transfer facility to be
credited with the withdrawn shares of Preferred Stock or otherwise comply with
the book-entry transfer facility's procedures. All questions as to the validity
of notices of withdrawals, including time of receipt, will be determined by the
Company, and such determination will be final and binding on all parties.

     Endorsements; Guarantee of Signatures.

     If this Letter of Transmittal is signed by the registered holder(s) of the

record by two or more joint owners, all such owners must sign this Letter of
Transmittal.

     If a number of shares of Old Preferred Stock registered in different names
are tendered, it will be necessary to complete, sign and submit as many separate
copies of this Letter of Transmittal as there are different registrations of
shares of Old Preferred Stock.

     When this Letter of Transmittal is signed by the registered holder or
holders (which term, for the purposes described herein, shall include the
book-entry transfer facility whose name appears on a security listing as the
owner of the shares of Old Preferred Stock) of shares of Preferred Stock listed
and tendered hereby, no endorsements of certificates or separate written
instruments of transfer or exchange are required.

     If this Letter of Transmittal is signed by a person other than the
registered holder or holders of the shares of Old Preferred Stock listed, such
shares of Old Preferred Stock must be endorsed or accompanied by separate
written instruments of transfer or exchange in form satisfactory to the Company
and duly executed by the registered holder, in either case signed exactly as the
name or names of the registered holder or holders appear(s) on the shares of Old
Preferred Stock.

     If this Letter of Transmittal, any certificates or separate written
instruments of transfer or exchange are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such persons should so
indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.

     Endorsements on certificates or signatures on separate written instruments
of transfer or exchange required by this Instruction 3 must be guaranteed by an

who has not completed the Box entitled "Special Issuance Instructions" on this
Letter of Transmittal; or (ii) for the account of an Eligible Institution. In
the event that the signatures in this Letter of Transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by an eligible guarantor institution which is a member of The Securities
Transfer Agents medallion Program (STAMP). If shares of Old Preferred Stock are
registered in the name of a person other than the signer of this Letter of
Transmittal, the shares of Old Preferred Stock surrendered for exchange must be
endorsed by, or be accompanied by a written instrument or instruments of
transfer or exchange, in satisfactory form as determined by the Company, in its

other than the transfer and exchange of shares of Old Preferred Stock to the
Company or its order pursuant to the Exchange Offer, the amount of any such
transfer taxes (whether imposed on the registered holder or any other person)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exception therefrom is not submitted herewith the amount of such
transfer taxes will be billed directly to such tendering holder.

     Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the shares of Old Preferred Stock listed in

6.   Substitute Form W-9

     Each holder of shares of Old Preferred Stock whose shares of Old Preferred
Stock are accepted for exchange (or other payee) is required to provide a
correct taxpayer identification number ("TIN"), generally the holder's Social
Security or federal employer identification number, and certain other
information, on Substitute Form W-9, which is provided under "Important Tax
Information" below, and to certify that the holder (or other payee) is not
subject to backup withholding. Failure to provide the information on the
Substitute Form W-9 may subject the holder (or other payee) to a $50 penalty
imposed by the Internal Revenue Service and 31% federal income tax backup
withholding on payments made in connection with the shares of Old Preferred
Stock. The box in Part 3 of the Substitute Form W-9 may be checked if the holder
(or other payee) has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Part 3 is checked and a TIN
is not provided by the time any payment is made in connection with the shares of
Old Preferred Stock, 31% of all such payments will be withheld until a TIN is
provided.

9.   Requests for Assistance or Additional Copies.

     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter of Transmittal, may be

                            IMPORTANT TAX INFORMATION

     Under U.S. Federal income tax law, a holder of shares of Old Preferred
Stock whose shares of Old Preferred Stock are accepted for exchange may be
subject to backup withholding unless the holder provides EquiServe-First
Chicago Trust Division, as Paying Agent (the "Paying Agent"), through the
Exchange Agent, with either (i) such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 attached hereto, certifying that the TIN
provided on Substitute Form W-9 is correct (or that such holder of shares of Old
Preferred Stock is awaiting a TIN) and that (A) the holder of shares of Old
Preferred Stock has not been notified by the Internal Revenue Service that he or
she is subject to backup withholding as a result of a failure to report all
interest or dividends or (B) the Internal Revenue Service has notified the
holder of shares of Old Preferred Stock that he or she is no longer subject to
backup withholding; or (ii) an adequate basis for exemption from backup
withholding. If such holder of shares of Old Preferred Stock is an individual,
the TIN is such holder's social security number. If the Paying Agent is not
provided with the correct TIN, the holder of shares of Old Preferred Stock may
be subject to certain penalties imposed by the Internal Revenue Service.

     Certain holders of shares of Old Preferred Stock (including, among others,
all corporations and certain foreign individuals) are not subject to these
backup withholding and reporting requirements. However, exempt holders of shares
of Old Preferred Stock should indicate their exempt status on Substitute Form
W-9. For example, a corporation must complete the Substitute Form W-9, providing
its TIN and indicating that it is exempt from backup withholding. In order for a
foreign individual to qualify as an exempt recipient, the holder must submit a
Form W-8, signed under penalties of perjury, attesting to that individual's
exempt status. A Form W-8 can be obtained from the Paying Agent. 

     If backup withholding applies, the Paying Agent is required to withhold 31%
of any such payments made to the holder of shares of Old Preferred Stock or
other payee. Backup withholding is not an additional tax. Rather, the tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund may
be obtained from the Internal Revenue Service.

     The box in Part 3 of the Substitute Form W-9 may be checked if the
surrendering holder of shares of Old Preferred Stock has not been issued a TIN
and has applied for a TIN or intends to apply for a TIN in the near future. If
the box in Part 3 is checked, the holder of shares of Old Preferred Stock or
other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Paying Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Paying Agent.

     The holder of shares of Old Preferred Stock is required to give the Paying
Agent the TIN (e.g., social security number or employer identification number)
of the record owner of the shares of Old Preferred Stock.
