                               PROSPECTUS SUMMARY

   The following summary highlights some information from this prospectus. It
may not contain all of the information that may be important to you. For a more
complete understanding of the exchange offer, we encourage you to read the
entire prospectus and the documents we have referred you to.

                          Exodus Communications, Inc.

   Exodus Communications is a leading provider of Internet system and network
management solutions for enterprises with mission-critical Internet operations.
Our solutions include Internet Data Centers, network services, managed services
and professional services, which together provide the high performance,
scalability and expertise that enterprises need to optimize their complex
Internet operations. Exodus delivers its services from geographically
distributed, state-of-the-art Internet Data Centers that are connected through
a high performance dedicated and redundant backbone network. Our tailored
solutions are designed to integrate with existing enterprise systems
architectures and to enable customers to outsource the monitoring,
administration and optimization of their equipment, applications and overall
Internet operations. As of September 30, 1999, we had more than 1,700
customers, including installed and uninstalled customers under contract, and
managed over 16,000 customer servers worldwide. Our customers represent a
variety of industries, ranging from Internet companies such as Lycos, Inc.,
eBay Inc., MSN Hotmail (a subsidiary of Microsoft Corporation), Yahoo!GeoCities
and Inktomi Corporation, to media companies such as MSNBC, USA Today
Information Network, SportsLine USA, Inc. and E-Online!, to major enterprise
companies such as Applied Materials and Storage Networks.

   Because Internet usage is growing rapidly, businesses are increasing the
breadth and depth of their Internet product and services offerings. These
Internet operations are mission-critical for Internet-centric businesses and
are becoming increasingly mission-critical for many enterprises. In order to
ensure the quality, reliability, availability and redundancy of these mission-
critical Internet operations, corporate IT departments must make substantial
investments in facilities, personnel, equipment and networks which must be
continuously upgraded to reflect changing technologies and must rapidly scale
as the enterprise grows. This recurring and significant investment is an
inefficient use of resources and, as a result, a significant need exists for
outsourcing arrangements that can increase performance, provide continuous
operation of Internet solutions and reduce Internet operating expenses. We
believe a significant opportunity exists for a highly focused company to
provide a combination of server hosting, Internet connectivity and managed and
professional services that will enable reliable, high performance of mission-
critical Internet operations.

   Exodus offers an integrated portfolio of solutions that provides customers
with a scalable, secure and high performance platform for the development,
deployment and proactive management of mission-critical Internet operations.
Our server hosting and Internet connectivity services are offered through our
Internet Data Centers' redundant backbone network of multiple high speed OC-3
and OC-12 lines, along with our public and private network interconnections. We
continue to upgrade our network in order to accommodate expected traffic
growth. Our managed services include performance monitoring, site management
reports, data backup and content delivery and management services, security
services and professional services. These services provide the foundation for
high performance, availability, scalability and reliability of customers'
Internet operations. In addition, we integrate best-of-breed technologies from
leading vendors with our industry expertise and proprietary technology.

   Our objective is to become the leading provider of Internet system and
network management solutions for enterprises with mission-critical Internet
operations. To achieve this objective, we intend to:

  .  Position Exodus as the leader in this market;

  .  Focus on enhancing systems and network management, Internet technology
     services and professional services;

  .  Accelerate our global expansion;

                                       1
<PAGE>


  .  Leverage our expertise to address new market opportunities; and

  .  Continue to establish strategic relationships for distribution and
     technology.

   We began offering server hosting and Internet connectivity services in late
1995, opened our first dedicated Internet Data Center in August 1996, and
introduced managed services in 1997 and professional services in 1998. We
currently operate 17 domestic Internet Data Centers located in nine
metropolitan areas: Atlanta, Austin, Boston, Chicago, Los Angeles, New York,
Seattle, Silicon Valley and Washington, D.C. In June 1999, we opened our first
Internet Data Center outside of the United States in the London metropolitan
area. In December 1999, we acquired Global OnLine Japan Co., Ltd. of Tokyo,
Japan, which has an Internet Data Center located in Tokyo. Our Internet Data
Centers consist of approximately 1,600,000 gross square feet.

   Our principal executive offices are located at 2831 Mission College Blvd.,
Santa Clara, California 95054. Our telephone number is (408) 346-2200.

Recent Events

shares of our Common Stock and Common Stock subject to options in exchange for
all of the outstanding shares of common stock of Service Metrics and shares of
Service Metrics common stock subject to outstanding options, representing an
aggregate consideration of approximately $280.0 million as of the signing of

                                    otherwise a taxable event to the holders of
                                    notes. See "Material United States Federal
                                    Income Tax Considerations."

                                    agent in connection with the exchange offer
                                    for the dollar notes, and Chase Manhattan
                                    Bank London is serving as exchange agent in

 Resales of New Notes.............  Based on an interpretation by the
                                    Securities and Exchange Commission set
                                    forth in no-action letters issued to third
                                    parties, we believe that you may resell or
                                    otherwise transfer new notes issued in the
                                    exchange offer in exchange for old notes
                                    without restrictions under the federal
                                    securities laws. However, there are
                                    exceptions to this general statement. You
                                    may not freely transfer the new notes if:
                                    .  you are an affiliate of Exodus;
                                    .  you did not acquire the new notes in the
                                       ordinary course of your business;
                                    .  you have engaged in, intend to engage
                                       in, or have an arrangement or
                                       understanding with any person to
                                       participate in the distribution of the
                                       new notes; or
                                    .  you are a broker-dealer who acquired the
                                       old notes directly from us.
                                    Any holder subject to any of the exceptions
                                    above and each participating broker-dealer
                                    that receives new notes for its own account
                                    in the exchange offer in exchange for old
                                    notes that were acquired as a result of
                                    market making, must comply with the
                                    registration and prospectus delivery
                                    requirements of the Securities Act in
                                    connection with the resale of the new
                                    notes.
 Consequences of Not Exchanging     If you do not tender your old notes or your
  the Old Notes...................  old notes are not properly tendered, the
                                    existing transfer restrictions will
                                    continue to apply. The old dollar notes are
                                    currently eligible for sale pursuant to
                                    Rule 144A through the Portal Market and the
                                    old euro notes are in the process of being
                                    listed on the Luxembourg Stock Exchange.
                                    Application is expected to be made for
                                    listing the new euro notes on the
                                    Luxembourg Stock Exchange. We cannot assure
                                    you that we will be successful in these
                                    listings or of when the listings will be
                                    complete. Because we anticipate that most
                                    holders will elect to exchange old notes
                                    for new notes due to the absence of
                                    restrictions on the resale of new notes
                                    under the Securities Act in most cases, we
                                    anticipate that the liquidity of the market
                                    for any old notes remaining after the
                                    consummation of the exchange offer will be
                                    substantially limited. See "Risk Factors--
                                    There could be negative consequences to you
                                    if you do not exchange your old notes for

                      Summary Description of the New Notes

   The terms of the new notes and the old notes are identical in all respects,
except that the terms of the new notes do not include the transfer restrictions
and registration rights relating to the old notes. The old notes and the new
notes are referred to collectively as the notes.

   The new notes will bear interest from the most recent date to which interest
has been paid on the old notes. Accordingly, registered holders of new notes on
the relevant record date for the first interest payment date following the
completion of the exchange offer will receive interest accruing from the most
recent date on which interest has been paid. Old notes accepted for exchange
will cease to accrue interest from and after the date of completion of the
exchange offer. Holders of old notes whose old notes are accepted for exchange
will not receive any payment in respect of interest on the old notes otherwise
payable on any interest payment date that occurs on or after completion of the
exchange offer.

                                    15, 2002, we may redeem up to 35% of the
                                    aggregate outstanding principal amount of
                                    the dollar notes and up to 35% of the

                                    the euro notes with the net cash proceeds

                                    plus accrued and unpaid interest and
                                    liquidated damages, if any, to the date of
                                    redemption; provided that at least 65% of

 Change of Control................  In the event of a change of control (as
                                    described below), each holder shall have
                                    the right to require that we purchase the
                                    notes at a price equal to 101% of the
                                    principal amount, plus accrued and unpaid
                                    interest, and liquidated damages, if any,
                                    to the date of purchase. See "Risk
                                    Factors--We may not be able to effect
                                    repurchase of the notes upon a Change of

                                    indenture."
 Ranking..........................  The notes will be senior unsecured
                                    indebtedness ranking equally with our
                                    existing and future senior unsecured
                                    obligations and senior in right of payment
                                    to all of our subordinated indebtedness.
                                    The notes will be effectively subordinated
                                    to all secured indebtedness and to any
                                    liabilities of any of our subsidiaries,
                                    including trade payables. As of September
                                    30, 1999, we had approximately
                                    $79.1 million of secured indebtedness and
                                    outstanding liabilities of our
                                    subsidiaries. In addition, the notes rank
                                    equally with our $275.0 million of 11 1/4%
                                    Senior Notes due 2008 and are senior in
                                    right of payment to our $250.0 million of
                                    5% Convertible Subordinated Notes due March
                                    15, 2006 and our $500.0 million of 4 3/4%
                                    Convertible Subordinated Notes due July 15,
                                    2008. See "Risk Factors--Our substantial
                                    leverage and debt service obligations
                                    adversely affect our cash flow."
 Restrictive Covenants............  The indenture governing the notes contains
                                    covenants that, among other things, limit
                                    our ability to incur specific types of
                                    debt, pay dividends, make distributions,
                                    make specific types of investments or other
                                    restricted payments, sell assets, enter
                                    into specified transactions with
                                    affiliates, incur liens, engage in mergers

                                    subsidiaries (as defined)
                                    to issue capital stock and make guarantees.

            Summary Supplemental Consolidated Financial Information

   The following summary supplemental consolidated financial information should
be read in conjunction with our supplemental consolidated financial statements
and related notes and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included elsewhere in this prospectus. The
supplemental consolidated financial statements have been prepared to give
retroactive effect to the merger with Service Metrics, Inc. ("SMI") on November
23, 1999. The summary supplemental consolidated financial information for each
of the years in the three-year period ended December 31, 1998 is derived from
our supplemental consolidated financial statements that have been audited by
KPMG LLP, independent auditors. The summary supplemental consolidated financial
information as of September 30, 1999 and for the nine months ended September
30, 1998 and September 30, 1999 is derived from our unaudited supplemental
condensed consolidated financial statements for these periods. Historical
results are not necessarily indicative of the results to be expected in the
future.

   "EBITDA" represents earnings (loss) before net interest expense, income
taxes, depreciation, amortization, including amortization of deferred stock
compensation, and other noncash charges. EBITDA should not be used as an
alternative to operating loss or net cash provided by (used for) operating
activities, investing activities or financing activities, each as measured
under generally accepted accounting principles. In addition, EBITDA may not be
comparable to other similarly titled information from other companies. However,
our management believes that EBITDA is an additional meaningful measure of
performance and liquidity. With respect to the captions entitled "Deficiency of
earnings available to cover fixed charges", earnings consist of income (loss)
before provision for income taxes plus fixed charges. Fixed charges consist of
interest charges and amortization of debt expense and discount or premium
related to indebtedness, whether expensed or capitalized and the portion of
rental expense that we believe to be representative of interest.

                                  RISK FACTORS

   Holders of old notes should carefully consider the information set forth
under the caption "Risk Factors" and all other information set forth in this
prospectus before tendering their old notes in the exchange offer. The risk
factors set forth in this prospectus, other than "Risk Factors--There could be
negative consequences to you if you do not exchange your old notes for new
notes," are generally applicable to the old notes as well as the new notes.

There could be negative consequences to you if you do not exchange your old
notes for new notes

   Any old notes tendered and exchanged in the exchange offer will reduce the
aggregate principal amount of old notes outstanding. Because we anticipate that
most holders will elect to exchange their old notes for new notes due to the
absence of most restrictions on the resale of new notes, we anticipate that the
liquidity of the market for any old notes remaining outstanding after the
exchange offer may be substantially limited. Following the consummation of the
exchange offer, holders who did not tender their old notes generally will not
have any further registration rights under the registration rights agreement,
and these old notes will continue to be subject to restrictions on transfer.
The old dollar notes are currently eligible for sale under Rule 144A through
the Portal Market, and the old euro notes are in the process of being listed on
the Luxembourg Stock Exchange. Application is expected to be made for listing
the new euro notes on the Luxembourg Stock Exchange. We cannot assure you that
we will be successful in these listings or of when the listings will be
complete.

   As a result of making the exchange offer, we will have fulfilled our
obligations under the registration rights agreement. Holders who do not tender
their old notes generally will not have any further registration rights or
rights to receive the liquidated damages specified in the registration rights
agreement for our failure to register the new notes.

   The old notes that are not exchanged for new notes will remain restricted
securities. Accordingly, the old notes may be resold only:

  .  to Exodus or one of its subsidiaries;

  .  to a qualified institutional buyer;

  .  to an institutional accredited investor;

  .  to a party outside the United States under Regulation S under the
     Securities Act;

  .  under an exemption from registration provided by Rule 144 under the
     Securities Act; or

  .  under an effective registration statement.

Our short operating history and heavy losses make our business difficult to
evaluate

   Our limited operating history makes evaluating our business operations and
our prospects difficult. We began offering server hosting and Internet
connectivity services in 1995, opened our first dedicated Internet Data Center
in August 1996 and introduced managed services in 1997 and professional
services in 1998. Due to our short operating history, our business model is
still evolving. We have incurred operating losses and negative cash flows each
fiscal quarter and year since 1995. Our accumulated deficit was approximately
$175.3 million at September 30, 1999. We anticipate continuing to make
significant investments in new Internet Data Centers and network
infrastructure, product development, sales and marketing programs and
personnel. We believe that we will continue to experience net losses on a
quarterly and annual basis for the foreseeable future. We may also use
significant amounts of cash and/or equity to acquire complementary businesses,
products, services or technologies. Although we have experienced significant
growth in revenues in recent periods, this growth rate is not necessarily
indicative of future operating results. It is possible that we may never
achieve profitability on a quarterly or an annual basis.

Our operating results have fluctuated widely and we expect this to continue

   We have experienced significant fluctuations in our results of operations on
a quarterly and an annual basis. We expect to continue to experience
significant fluctuations due to a variety of factors, many of which are outside
of our control, including:

  .  demand for and market acceptance of our services;

  .  reliable continuity of service and network availability;

  .  the ability to increase bandwidth as necessary, both on our network and
     at our interconnection points with other networks;

  .  costs related to the acquisition of network capacity and arrangements
     for interconnections with third-party networks;

  .  customer retention and satisfaction;

  .  capacity utilization of our Internet Data Centers;

  .  the timing, magnitude and integration of acquisitions of complementary
     businesses and assets;

  .  the timing of customer installations;

  .  the provision of customer discounts and credits;

  .  the mix of services sold by us;

  .  the timing and success of marketing efforts and service introductions by
     us and our competitors;

  .  the timing and magnitude of capital expenditures, including construction
     costs relating to the expansion of operations;

  .  the timing of expansion of existing Internet Data Centers and completion
     of new Internet Data Centers;

  .  the introduction by third parties of new Internet and networking
     technologies;

  .  changes in our pricing policies and those of our competitors; and

  .  fluctuations in bandwidth used by customers.

   In addition, a relatively large portion of our expenses are fixed in the
short-term, particularly with respect to telecommunications, depreciation,
substantial interest expenses, real estate and personnel. Therefore, our
results of operations are particularly sensitive to fluctuations in revenues.
Furthermore, if we were to become unable to continue leveraging third-party
products in our services offerings, our product development costs could
increase significantly. Finally, many of our customers are emerging growth
companies which may have negative cash flows, and there is the possibility that
we will not be able to collect receivables on a timely basis.

Our rapid expansion produces a significant strain on our business and requires
us to expend substantial resources

   The expansion of our network through the opening of additional Internet Data
Centers in geographically diverse locations is one of our key strategies. We
currently have 17 Internet Data Centers located in nine metropolitan areas of
the United States: Atlanta, Austin, Boston, Chicago, Los Angeles, New York,
Seattle, Silicon Valley and Washington, D.C. In June, we opened our first
Internet Data Center outside of the United States in the London metropolitan
area. In December 1999, we acquired Global OnLine Japan Co., Ltd. of Tokyo,
Japan, which has an Internet Data Center located in Tokyo. To expand
successfully, we must be able to assess markets, locate and secure new Internet
Data Center sites, install telecommunications and Internet Data Center
facilities and establish additional peering interconnections with Internet
service providers. To manage this expansion effectively, we must continue to
improve our operational and financial systems and expand, train

                                       11
<PAGE>

and manage our employee base. Our inability to establish additional Internet
Data Centers or effectively manage our expansion would have a material adverse
effect upon our business.

   We expect to expend substantial resources for leases and/or the purchase of
real estate, significant improvements of facilities, purchase of complementary
businesses, assets and equipment, implementation of multiple telecommunications
connections and hiring of network, administrative, customer support and sales
and marketing personnel with the establishment of each new Internet Data
Center. Moreover, we expect to make significant investments in sales and
marketing and the development of new services as part of our expansion
strategy. The failure to generate sufficient cash flows or to raise sufficient
funds may require us to delay or abandon some or all of our development and
expansion plans or otherwise forego market opportunities, making it difficult
for us to generate additional revenue and to respond to competitive pressures.

   In general, it takes us at least six months to select the appropriate
location for a new Internet Data Center, construct the necessary facilities,
install equipment and telecommunications infrastructure and hire operations and
sales personnel. Expenditures commence well before the Internet Data Center
opens, and it takes an extended period for us to approach break-even capacity
utilization. As a result, we expect that individual Internet Data Centers will
experience losses for in excess of one year from the time they are opened. We
incur further expenses from sales personnel hired to test market our services
in markets where there is no Internet Data Center. Growth in the number of our
Internet Data Centers is likely to increase the amount and duration of losses.
In addition, if we do not attract customers to new Internet Data Centers in a
timely manner, or at all, our business would be materially adversely affected.

We compete with much larger companies and there are few barriers to entry, and
if we cannot compete effectively, we will lose business

   Our market is intensely competitive. There are few substantial barriers to
entry, and we expect to face additional competition from existing competitors
and new market entrants in the future. Many companies have announced recently
that they intend to begin providing and/or greatly expand their service
offerings that are competitive with our services. The principal competitive
factors in this market include:

  .  Internet system engineering and other expertise;

  .  customer service;

  .  network capability, reliability, quality of service and scalability;

  .  the variety of services offered;

  .  access to network resources, including circuits, equipment and
     interconnection capacity to other networks;

  .  broad geographic presence;

  .  price;

  .  the ability to maintain and expand distribution channels;

  .  brand name;

  .  the timing of introductions of new services;

  .  network security; and

  .  financial resources.

   There can be no assurance that we will have the resources or expertise to
compete successfully in the future. Our current and potential competitors in
the market include:

  .  providers of server hosting services;


                                       12
<PAGE>

  .  national, foreign and regional ISPs;

  .  global, regional and local telecommunications companies and Regional
     Bell Operating Companies;

  .  IT outsourcing firms; and

  .  other technology services and products companies.

   Many of our competitors have substantially greater resources, more
customers, longer operating histories, greater name recognition and more
established relationships in the industry. As a result, these competitors may
be able to develop and expand their network infrastructures and service
offerings more quickly, devote greater resources to the marketing and sale of
their products and adopt more aggressive pricing policies. In addition, these
competitors have entered and will likely continue to enter into business
relationships to provide additional services competitive with those we provide.

   Some of our competitors may be able to provide customers with additional
benefits in connection with their Internet system and network management
solutions, including reduced communications costs, which could reduce the
overall costs of their services relative to ours. We may not be able to offset
the effects of any price reductions. In addition, we believe our market is
likely to encounter consolidation in the near future, which could result in
increased prices and other competition.

Our market is new and our services may not be generally accepted by enterprises
looking to outsource their mission-critical Internet operations, which could
harm our operating results

   The market for Internet system and network management solutions has only
recently begun to develop, is evolving rapidly and is characterized by an
increasing number of market entrants. This market may not prove to be viable
or, if it becomes viable, may not continue to grow. Our future growth depends
on the willingness of enterprises to outsource the system and network
management of their mission-critical Internet operations and our ability to
market our services in a cost-effective manner to a sufficiently large number
of customers. If this market fails to develop, or develops more slowly than
expected, or if our services do not achieve market acceptance, our business
would be adversely affected. In addition, in order to be successful we must be
able to differentiate ourselves from our competition through our service
offerings.

Our substantial leverage and debt service obligations adversely affect our cash
flow

   We have substantial amounts of outstanding indebtedness, primarily from our
11 1/4% senior notes, 10 3/4% senior notes, 4 3/4% convertible subordinated
notes and 5% convertible subordinated notes. There is the possibility that we
may be unable to generate cash sufficient to pay the principal of, interest on
and other amounts due in respect of, our debt when due. As of September 30,
1999, we had debt of approximately $589.7 million and available borrowings of
up to an additional $1.2 million. In addition, in December 1999, we incurred
additional debt of $375.0 million aggregate principal amount of our 10 3/4%
senior notes and (Euro)125.0 million aggregate principal amount of the 10 3/4%
senior notes as well as $500.0 million aggregate principal amount of our 4 3/4%
convertible subordinated notes. We will also have the right to issue additional
10 3/4% senior notes on or prior to December 8, 2000 in an aggregate principal
amount not to exceed $100.0 million. In addition, we expect to add additional
equipment loans and lease lines to finance capital expenditures for our
Internet Data Centers and to obtain additional long term debt, working capital
lines of credit and lease lines. We cannot be certain that any financing
arrangements will be available.

   Our substantial leverage could have significant negative consequences,
including:

  .  increasing our vulnerability to general adverse economic and industry
     conditions;

  .  limiting our ability to obtain additional financing;

  .  requiring the dedication of a substantial portion of our expected cash
     flow from operations to service our indebtedness, thereby reducing the
     amount of our expected cash flow available for other purposes, including
     capital expenditures;

                                       13
<PAGE>

  .  limiting our flexibility in planning for, or reacting to, changes in our
     business and the industry in which we compete; and

  .  placing us at a possible competitive disadvantage compared to less
     leveraged competitors and competitors that have better access to capital
     resources.

We are subject to restrictive covenants in our note indentures that limit our
flexibility in managing our business

   Our senior notes and convertible subordinated notes contain various
restrictions on our ability to incur debt, pay dividends or make other
restricted payments, sell assets, enter into affiliate transactions and take
other actions. Furthermore, our existing financing arrangements are, and future
financing arrangements are likely to be, secured by substantially all of our
assets. The existing financing arrangements require, and future financing
arrangements are likely to require, that we maintain specific financial ratios
and comply with covenants restricting our ability to incur debt, pay dividends
or make other restricted payments, sell assets, enter into affiliate
transactions or take other actions.

   In addition, a number of instruments evidencing our debt restrict the manner
in which this debt and debt incurred in the future may be used.

We must manage growth effectively by expanding operating and financial
procedures, controls and systems or our business will be harmed

   We are experiencing, and expect to continue experiencing, rapid growth with
respect to the building of our Internet Data Centers and network
infrastructure, expansion of our service offerings, geographic expansion,
expansion of our customer base and increases in the number of employees. This
growth has placed, and we expect it to continue to place, a significant strain
on our financial, management, operational and other resources, including our
ability to ensure customer satisfaction. This expansion also requires
significant time commitment from our senior management and places a significant
strain on their ability to manage the existing business. In addition, we are
required to manage multiple relationships with a growing number of third
parties as we seek to complement our service offerings. Our ability to manage
our growth effectively will require us to continue to expand operating and
financial procedures and controls, to replace or upgrade our operational,
financial and management information systems and to attract, train, motivate
and retain key employees. We have recently hired many key employees and
officers, and as a result, our entire management team has worked together for
only a brief time. In addition, we intend to hire additional senior management
personnel to support our growth and expansion of our business. If our
executives are unable to manage growth effectively, our business could be
materially adversely affected.

We may experience difficulty in integrating our recent acquisitions which could
harm our operating results

   In October 1998 we acquired the assets of Arca Systems, Inc., in February
1999 we acquired American Information Systems, Inc., in July 1999 we acquired
Cohesive Technology Solutions, Inc, in November 1999 we acquired Service
Metrics, Inc. and in December 1999 we acquired Global OnLine Japan Co., Ltd.
Furthermore, in January 2000, we agreed to acquire KeyLabs, Inc. We continue to
expend resources integrating Cohesive and Service Metrics and the personnel
hired in connection with acquisitions. As we acquire additional companies, we
may incur expenses to, among other things, remediate Year 2000 problems
relating to these acquired companies.

   We believe that our future growth depends, in part, upon the acquisition of
complementary businesses, products, services or technologies. After purchasing
a company, we could have difficulty in assimilating that company's technology,
personnel and operations. In addition, the key personnel of the acquired
company may decide not to work for us. These difficulties could disrupt our
ongoing business, distract our management and

                                       14
<PAGE>

employees and increase our expenses. In addition, future acquisitions by us may
require us to incur additional debt, result in large one-time write-offs or
create goodwill or other intangible assets that could result in amortization
expenses.

System failures could lead to significant costs

   We must protect our network infrastructure and customers' equipment against
damage from human error, physical or electronic security breaches, power loss
and other facility failures, fire, earthquake, flood, telecommunications
failure, sabotage, vandalism and similar events. Despite precautions we have
taken, a natural disaster or other unanticipated problems at one or more of our
Internet Data Centers could result in interruptions in our services or
significant damage to customer equipment. In addition, failure of any of our
telecommunications providers, such as MCI WorldCom, Qwest Communications
Corporation and Global Crossing, to provide consistent data communications
capacity, and local exchange carriers to provide interconnection agreements,
could result in interruptions in our services. Any damage to or failure of our
systems or service providers could result in reductions in, or terminations of,
services supplied to our customers, which could have a material adverse effect
on our business. In the past, we have experienced interruptions in specific
circuits within our network resulting from events outside our control, which
led to short-term degradation in the level of performance of our network.

Customer satisfaction with our services is critical to our success

   Our customers demand a very high level of service. Our customer contracts
generally provide a limited service level commitment related to the continuous
availability of service on a 24 hours per day, seven days per week basis. This
commitment is generally limited to a credit consisting of free service for a
short period of time for disruptions in Internet transmission services. To
date, only a limited number of customers have been entitled to this credit. If
we incur significant service level commitment obligations in connection with
system downtime, our liability insurance may not be adequate to cover these
expenses. As customers outsource more mission-critical operations to us, we are
subject to increased liability claims and customer dissatisfaction if our
systems fail or our customers otherwise become unsatisfied.

Our ability to expand our network is unproven and will require substantial
financial, operational and management resources

   To satisfy customer requirements, we must continue to expand and adapt our
network infrastructure. We are dependent on MCI WorldCom, Qwest, Global
Crossing and other telecommunications providers for our network capacity,
including our dedicated clear channel network. The expansion and adaptation of
our telecommunications infrastructure will require substantial financial,
operational and management resources as we negotiate telecommunications
capacity with network infrastructure suppliers. Due to the limited deployment
of our services to date, our ability to connect and manage a substantially
larger number of customers at high transmission speeds is unknown. We have yet
to prove our network's ability to be scaled up to higher customer levels while
maintaining superior performance. Furthermore, it may be difficult for us to
increase quickly our network capacity in light of current necessary lead times
within the industry to purchase circuits and other critical items. If we fail
to achieve or maintain high capacity data transmission circuits, customer
demand could diminish because of possible degradation of service. In addition,
as we upgrade our telecommunications infrastructure to increase bandwidth
available to our customers, we expect to encounter equipment or software
incompatibility which may cause delays in implementation.

We depend on network interconnections provided by third parties who may raise
their fees or deny access

   We rely on a number of public and private network interconnections to allow
our customers to connect to other networks. If the networks with which we
interconnect were to discontinue their interconnections, our ability to
exchange traffic would be significantly constrained. Furthermore, our business
will be harmed if these

                                       15
<PAGE>

networks do not add more bandwidth to accommodate increased traffic. Many of
the companies with which we maintain interconnections are our competitors.
There is nothing to prevent any networks, many of which are significantly
larger than we are, from charging high usage fees or denying access. In the
future, networks could refuse to continue to interconnect directly with us,
might impose significant costs on us or limit our customers' access to their
networks. In this event, we may not be able on a cost-effective basis to access
alternative networks to exchange our customers' traffic. In addition, we may
not be able to pass through to our customers any additional costs of utilizing
these networks. In these cases, our business could be harmed.

Difficulties presented by international economic, political, legal, accounting
and business factors could harm our business in international markets

   A component of our strategy is to expand into international markets. We
opened our first Internet Data Center outside of the United States in the
London metropolitan area in June 1999 and acquired an Internet Data Center in
Tokyo through our acquisition of Global OnLine Japan Co., Ltd. in December
1999. Furthermore, we plan to open additional international Internet Data
Centers by the end of 2000. In order to expand our international operations, we
may enter into joint ventures or outsourcing agreements with third parties,
acquire rights to high-bandwidth transmission capability, acquire complementary
businesses or operations, or establish and maintain new operations outside of
the United States. Thus, we may depend on third parties to be successful in our
international operations. In addition, the rate of development and adoption of
the Internet has been slower outside of the United States, and the cost of
bandwidth has been higher, which may adversely affect our ability to expand
operations and may increase our cost of operations internationally. The risks
inherent in conducting business internationally include:

  .  unexpected changes in regulatory requirements, export restrictions,
     tariffs and other trade barriers;

  .  challenges in staffing and managing foreign operations;

  .  differences in technology standards;

  .  employment laws and practices in foreign countries;

  .  longer payment cycles and problems in collecting accounts receivable;

  .  political instability;

  .  fluctuations in currency exchange rates and imposition of currency
     exchange controls; and

  .  potentially adverse tax consequences.

We might not be successful in our attempts to keep up with rapid technological
change and evolving industry standards

   Our future success will depend on our ability to offer services that
incorporate leading technology and address the increasingly sophisticated and
varied needs of our current and prospective customers. Our market is
characterized by rapidly changing and unproven technology, evolving industry
standards, changes in customer needs, emerging competition and frequent new
service introductions. Future advances in technology may not be beneficial to,
or compatible with, our business. In addition, we may not be able to
incorporate advances on a cost-effective and timely basis. Moreover,
technological advances may have the effect of encouraging our current or future
customers to rely on in-house personnel and equipment to furnish the services
we currently provide. In addition, keeping pace with technological advances may
require substantial expenditures and lead time.

   We believe that our ability to compete successfully is also dependent upon
the continued compatibility and interoperability of our services with products,
services and architectures offered by various vendors. Although we work with
various vendors in testing newly developed products, these products may not be
compatible with our infrastructure or adequate to address changing customer
needs. For instance, existing networking hardware may not be immediately
compatible with leading edge telecommunications infrastructure services. This

                                       16
<PAGE>

incompatibility would require us to make significant investments to achieve
compatibility. Although we intend to support emerging standards, industry
standards may not be established or we may not be able to timely conform to new
standards. Our failure to conform to a prevailing standard, or the failure of a
common standard to emerge, could have a material adverse effect on our
business.

System security risks could disrupt our services

   The ability to provide secure transmissions of confidential information over
networks accessible to the public is a significant barrier to electronic
commerce and communications. A portion of our services rely on encryption and
authentication technology licensed from third parties. Despite a variety of
network security measures taken by us, we cannot assure that unauthorized
access, computer viruses, accidental or intentional actions and other
disruptions will not occur. Our Internet Data Centers have experienced and may
in the future experience delays or interruptions in service as a result of the
accidental or intentional actions of Internet users, current and former
employees of Exodus or others. Furthermore, inappropriate use of the network by
third parties could also jeopardize the security of confidential information,
such as customer and Exodus passwords as well as credit card and bank account
numbers, stored in our computer systems or those of our customers. As a result,
we could become liable to others and lose existing or potential customers. The
costs required to eliminate computer viruses and alleviate other security
problems could be prohibitively expensive. In addition, the efforts to address
these problems could result in interruptions, delays or cessation of service to
our customers.

We depend on third-party equipment and software suppliers

   We depend on vendors to supply key components of our telecommunications
infrastructure and system and network management solutions. Some of the
telecommunications services and networking equipment is available only from
sole or limited sources. For instance, the routers, switches and modems we use
are currently supplied primarily by Cisco Systems, Inc. We typically purchase
or lease all of our components under purchase orders placed from time to time.
We do not carry significant inventories of components and have no guaranteed
supply arrangements with vendors. If we are unable to obtain required products
or services on a timely basis and at an acceptable cost, our business would be
harmed. In addition, if our sole or limited source suppliers do not provide
products or components that comply with evolving Internet and
telecommunications standards or that interoperate with other products or
components we use, our business would be harmed. For example, we have
experienced performance problems, including previously unknown software and
firmware bugs, with routers and switches that have caused temporary disruptions
in and impairment of network performance. In addition, we expect to depend for
a time on third parties to deliver and manage our services from certain
international operations.

Government regulation and legal uncertainties may harm our business

   Laws and regulations directly applicable to communications and commerce over
the Internet are becoming more prevalent. The United States Congress has
recently considered enacting Internet laws regarding children's privacy,
copyrights, taxation and the transmission of sexually explicit material. The
European Union also recently enacted its own privacy regulations. The law of
the Internet, however, remains largely unsettled, even in areas where there has
been some legislative action. It may take years to determine whether and how
existing laws such as those governing intellectual property, privacy, libel and
taxation apply to the Internet. In addition, the growth and development of the
market for online commerce may prompt calls for more stringent consumer
protection laws, both in the United States and abroad, that may impose
additional burdens on companies conducting business online. The adoption or
modification of laws or regulations relating to the Internet could adversely
affect our business. We provide services over the Internet in all states in the
United States and in many foreign countries, and we facilitate the activities
of our customers in these jurisdictions. As a result we may be required to
qualify to do business, or be subject to taxation, or be subject to other laws
and regulations, in these jurisdictions even if we do not have a physical
presence or employees or property in these jurisdictions. The application of
these multiple sets of laws and regulations is uncertain, but we could find
that Exodus is subject to regulation, taxation, enforcement or other liability
in unexpected ways, which could materially adversely affect our business.

                                       17
<PAGE>

We could be held liable for the information disseminated through our network

   The law relating to the liability of online services companies and Internet
access providers for information carried on or disseminated through their
networks is currently unsettled. The Child Online Protection Act of 1998
imposes criminal penalties and civil liability on anyone engaged in the
business of selling or transferring material that is harmful to minors, by
means of the World Wide Web, without restricting access to this type of
material by underage persons. Numerous states have adopted or are currently
considering similar types of legislation. The imposition upon us and other
Internet network providers of potential liability for information carried on or
disseminated through systems could require us to implement measures to reduce
exposure to liability, which may require the expenditure of substantial
resources, or to discontinue various service or product offerings. Further, the
costs of defending against any claims and potential adverse outcomes of these
claims could have a material adverse effect on our business. While we carry
professional liability insurance, it may not be adequate to compensate or may
not cover us in the event we become liable for information carried on or
disseminated through our networks.

   Some businesses, organizations and individuals have in the past sent
unsolicited commercial e-mail messages advertising sites hosted at our
facilities to a massive number of people. This practice, known as "spamming,"
has led to some complaints against us. In addition, some ISPs and other online
services companies could deny network access to us if we allow undesired
content or spamming to be transmitted through our networks. Although we
prohibit customers by contract from spamming, we cannot be sure that customers
will not engage in this practice, which could have a material adverse effect on
our business.

Our future success depends on our key personnel

   Our success depends in significant part upon the continued services of our
key technical, sales and senior management personnel. Any officer or employee
can terminate his or her relationship at any time. If we lose the services of
one or more of our key employees or are unable to attract additional qualified
personnel, our business would be adversely affected. We do not carry key-person
life insurance for any of our employees.

If the Internet and Internet infrastructure development do not continue to
grow, our business will be harmed

   Our success depends in large part on continued growth in the use of the
Internet. Critical issues concerning the commercial use of the Internet,
including security, reliability, cost, ease of access, quality of service and
necessary increases in bandwidth availability, remain unresolved and are likely
to affect the development of the market for our services. In addition, the rate
of development and adoption of the Internet has been slower outside of the
United States and the cost of bandwidth has been higher. The recent growth in
the use of the Internet has caused frequent periods of performance degradation,
requiring the upgrade of routers and switches, telecommunications links and
other components forming the infrastructure of the Internet by ISPs and other
organizations with links to the Internet. Any perceived degradation in the
performance of the Internet as a whole could undermine the benefits of our
services. Consequently, the emergence and growth of the market for our services
is dependent on improvements being made to the entire Internet infrastructure
to alleviate overloading and congestion.

We face risks associated with protection and enforcement of intellectual
property rights

   We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect proprietary
rights in our products and services. We have no patented technology that would
preclude or inhibit competitors from entering our market. Although we have
entered into confidentiality agreements with our employees, contractors,
suppliers, distributors and appropriate customers to limit access to and
disclosure of our proprietary information, these may prove insufficient to
prevent misappropriation of our technology or to deter independent third-party
development of similar technologies. In addition, the laws of various foreign
countries may not protect our products, services or intellectual property
rights to the same extent as do the laws of the United States.

                                       18
<PAGE>

   In addition to licensing technologies from third parties, we are developing
and acquiring additional proprietary intellectual property. Third parties may
try to claim that our products or services infringe their intellectual
property. We expect that participants in our markets will be increasingly
subject to infringement claims. Any claim, whether meritorious or not, could be
time consuming, result in costly litigation, cause product installation delays
or require us to enter into royalty or licensing agreements. These royalty or
licensing agreements might not be available on terms acceptable to us or at
all.

Potential risks related to the Year 2000 problem might harm our business

   The Year 2000 problem stems from the use of a two digit date to represent
the year (for example, 85 = 1985) in computer software and firmware. As a
result, many currently installed computer systems are not capable of
distinguishing dates beginning with the Year 2000 from dates prior to the Year
2000. As a result, computer systems or applications used by many companies in a
wide variety of industries may experience operating difficulties unless the
systems or applications are modified to process adequately information related
to the date change. Significant uncertainty exists in the software and other
industries concerning the scope and magnitude of problems associated with the
century change. To the extent Year 2000 issues cause significant delay in, or
cancellation of decisions to purchase products or product support, due to the
reallocation of resources to address Year 2000 issues or otherwise, our
business could be materially adversely affected.

   We recognize the need to ensure our operations will not be adversely
impacted by Year 2000 issues. We have put into place a comprehensive Year 2000
Risk Management initiative that is adequately funded, staffed and managed. This
initiative's scope covers both our IT systems and non-IT systems and addresses
all areas of the Year 2000 issues as defined by the Information Technology
Association of America (ITAA). Our internal inventory audit was completed
January 1999. Due to our acquisition of Cohesive, we expanded the independent
review of our Year 2000 assessment. The review was completed in the third
quarter of 1999. Due to our recent acquisition of Service Metrics, Inc., we
performed an independent review of their Year 2000 program. The review was
completed in December 1999. We believe that their internal management
information systems and other systems are Year 2000 compliant. In December
1999, we acquired Global OnLine Japan. We believe that their internal
management information systems and other systems are Year 2000 compliant. We
continue to monitor their program.

   We have determined that our Internet Data Center equipment is currently Year
2000 compliant. We will continue to monitor vendors and suppliers for any
potential Year 2000 issues. Likewise, based on the on-going assessment relative
to our current software service offerings, we believe that the current versions
of these products are Year 2000 compliant. We have reviewed, and continue to
review, internal management information and other systems in order to identify
and modify those products, services or systems to ensure that they remain Year
2000 compliant. We have completed the assessment of the Year 2000 compliance of
Cohesive's internal management information and other systems. Based on our
assessment to date, we believe that our internal management information and
other systems and Cohesive's internal management information and other systems
are Year 2000 compliant. We do not foresee any significant issues with internal
IT and internal non-IT systems remaining Year 2000 compliant.

   Our Year 2000 initiative also addresses vendor relationships (both IT and
non-IT) and their readiness/preparedness relating to Year 2000 issues. IT
vendors include software providers, hardware providers, service providers, off
the shelf software publishers and IT consultants. Non-IT providers include
electric power suppliers, vendors of uninterruptable power supplies and
generators, telecommunications service providers, business partners, facilities
maintainers and other non-IT service contractors. In the event that third
parties cannot provide us with products, services or systems that are Year 2000
compliant on a timely basis, our business could be materially adversely
affected. To date, we have not discovered nor do we anticipate any material
issues with vendors and service providers. Evaluation of vendor Year 2000
preparedness is an on-going process. As our Year 2000 evaluation does not
evaluate our vendors' vendors nor our vendors' customer base viability issues,
we have put in place contingency plans. To minimize our risk, effective
November 15, 1999 through January 4, 2000, we instituted a freeze on the
introduction of new technology, new software versions and new configurations.
During that period, we utilized only hardware approved for production.

                                       19

   Many of our customers maintain their Internet operations on servers which
may be impacted by Year 2000 complications. The failure of our customers to
ensure that their servers are Year 2000 compliant could have a material adverse
effect on our customers, which in turn could have a material adverse effect on
our business, if our customers are forced to cease or interrupt Internet
operations or experience malfunctions related to their equipment.

   We have established procedures for evaluating and managing the risks and
costs associated with the Year 2000 problem. Funding and execution for this
initiative is within our existing business units and operating budgets and is
not viewed as material. Based on our current assessment, we believe the costs,
excluding employee personnel time and effort and unanticipated liabilities, to
resolve Year 2000 issues should not exceed $900,000, of which we have incurred
approximately $800,000 as of December 31, 1999. We further estimate that the
time and effort required of our personnel to resolve Year 2000 issues will not
be material.

   While we believe our Year 2000 initiative to be prudent, properly funded and
staffed and well-managed, there can be no assurance that we will identify and
remedy all Year 2000 problems in a timely fashion, that any remedial efforts in
this regard will not involve significant time and expense, or that these
problems will not have a material adverse effect on our business.

The notes are effectively subordinated to our secured indebtedness and the
liabilities of our subsidiaries

   The notes are effectively subordinated to our secured debt to the extent of
the value of the assets securing the debt. The notes are effectively
subordinated to all liabilities, including trade payables and lease
obligations, of our subsidiaries. Any right we may have to receive assets of
any of our subsidiaries upon liquidation or reorganization will be effectively
subordinated to the claims of that subsidiary's creditors, including trade
creditors. As of September 30, 1999, we had approximately $64.3 million of
outstanding secured debt and our subsidiaries had approximately $17.4 million
of liabilities. The indenture governing the Notes contains limitations on our
ability and the ability of our subsidiaries to incur additional debt. However,
these limitations are subject to a number of exceptions, and there can be no
assurances that we will not incur significant additional debt in the future,
including debt to which the holders of the Notes would be effectively
subordinated. See "Description of Notes--Covenants--Limitation on Debt".

Our management has broad discretion in the allocation of the proceeds of the
sale of the notes

   We expect to use the net proceeds from the sale of the notes in December
1999 primarily to finance the purchase or other acquisition of assets or
businesses to be used in the System and Network Management Business (as defined
in the indenture governing the notes). Our management retains broad discretion
in allocating the proceeds from the sale of the notes. The failure of
management to apply the funds effectively could harm our business. See "Use of
Proceeds."

We may not be able to effect repurchase of the notes upon a Change of Control
in accordance with the terms of the indenture

   Upon the occurrence of a Change of Control (as defined elsewhere in this
prospectus), we may be required to purchase all or a portion of the notes at a
purchase price equal to 101% of the principal amount, plus accrued and unpaid
interest, if any, to the date of purchase. Prior to commencing such an offer to
purchase, we may be required to (1) repay in full all of our indebtedness that
would prohibit the repurchase of the notes or (2) obtain any consent required
to make the repurchases. If we are unable to repay all of this indebtedness or
are unable to obtain the necessary consents, we will be unable to offer to
purchase the notes. That failure would constitute an event of default under the
indenture. We may not have sufficient funds available at the time of any Change
of Control to repurchase the notes. The events that require a repurchase upon a
Change of Control under the indenture may also constitute events of default
under any of our indebtedness. See "Description of the Notes--Repurchase at the
Option of Holders."

You may find it difficult to sell your notes

   The old dollar notes are eligible for trading in the Portal Market. The old
euro notes are in the process of being listed on the Luxembourg Stock Exchange.
There is no existing trading market for the new notes, although we expect to
apply to list the new euro notes on the Luxembourg Stock Exchange. We cannot
assure you that we will be successful in these listings or of when the listings
will be complete. Accordingly, we cannot be sure that any market for the new
notes will develop, that the holders of the new notes will be able to sell
their notes or the prices at which any sales will be made. If a market for the
notes were to develop, the notes could trade at prices that may be higher or
lower than the exchange tender price of the old notes, as our previously
registered notes do. Prevailing market prices from time to time will depend on
many factors, including then existing interest rates, our operating results and
cash flow and the market for similar securities.

   In addition, the liquidity of, and trading markets for, the new notes may be
adversely affected by declines in the market for high-yield securities
generally. A decline may aversely affect liquidity and trading markets
independent of our financial performance or prospects.

                DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

   This prospectus includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange
Act. When used in this prospectus, the words "anticipate," "believe,"
"estimate," "will," "may," "intend" and "expect" and similar expressions
generally identify forward-looking statements. Although we believe that our
plans, intentions and expectations reflected in the forward-looking statements
are reasonable, we cannot be sure that they will be achieved. Forward-looking
statements in this prospectus include those relating to the expansion of our
network through the opening of additional Internet Data Centers and the timing
of openings, the upgrading of our telecommunications infrastructure, our
planned introduction of various new products and services, the possibility of
acquiring complementary businesses, products, services and technologies and our
ability to make required payments on our current and future debt instruments.
Actual results, performance or achievements could differ materially from those
contemplated by the forward-looking statements contained in this prospectus.
Important factors that could cause actual results to differ materially from our
forward-looking statements are set forth in this prospectus, including under
the heading "Risk Factors." These factors are not intended to represent a
complete list of the general or specific factors that may affect us. It should
be recognized that other factors, including general economic factors and
business strategies, may be significant, presently or in the future, and the
factors set forth in this prospectus may affect us to a greater extent than
indicated. All forward-looking statements attributable to us or persons acting
on our behalf are expressly qualified in their entirety by the cautionary
statements set forth in this prospectus. Except as required by law, we
undertake no obligation to update any forward-looking statement, whether as a
result of new information, future events or otherwise.

                                USE OF PROCEEDS

   We will not receive any proceeds from the issuance of the new notes offered
in the exchange offer. In consideration for issuing the new notes, we will
receive in exchange old notes in like principal amount, the terms of which are
identical in all respects to the new notes except for transfer restrictions and
registration rights. The old notes surrendered in exchange for new notes will
be retired and cancelled and cannot be reissued. Accordingly, issuance of the
new notes will not result in any increase in our indebtedness.

   The net proceeds from the sale of the old notes, after deducting the
underwriting discounts and offering expenses, was approximately $485.5 million.
The net proceeds will be used in the System and Network Management Business (as
defined in the indenture governing the notes), such as Internet Data Centers.
In the ordinary course of business, we evaluate potential acquisitions of
businesses, products, services and technologies. However, except as disclosed
in this prospectus, we have no present understandings, commitments or
agreements with respect to any acquisition of any businesses, products,
services or technologies. Pending these uses, we have invested the net proceeds
in investment-grade, short-term, interest-bearing securities. See "Risk
Factors--Our management has broad discretion in the allocation of the proceeds
of the offering of the old notes."

   The following table sets forth our unaudited capitalization as of September
30, 1999 on a supplemental actual basis, on an as adjusted basis to reflect the
receipt of the net proceeds from the sale of the notes, and as further adjusted

               SELECTED SUPPLEMENTAL CONSOLIDATED FINANCIAL DATA

   The following selected supplemental consolidated financial data should be
read in conjunction with our supplemental consolidated financial statements and
notes and "Management's Discussion and Analysis of Financial Condition and
Results of Operations" included elsewhere in this prospectus. The supplemental
consolidated financial statements have been prepared to give retroactive effect
to the merger with Service Metrics, Inc. on November 23, 1999. The supplemental
consolidated statement of operations data for each of the years in the three-
year period ended December 31, 1998, and the supplemental consolidated balance
sheet data as of December 31, 1997 and 1998, are derived from supplemental
consolidated financial statements that have been audited by KPMG LLP,
independent auditors, and are included elsewhere in this prospectus. The
supplemental consolidated statement of operations data for the nine-month
periods ended September 30, 1998 and September 30, 1999 and the supplemental
consolidated balance sheet data as of September 30, 1999 are derived from
supplemental unaudited condensed consolidated financial statements included
elsewhere in this prospectus. The supplemental consolidated statement of
operations data for the year ended December 31, 1995 and the supplemental
consolidated balance sheet data as of December 31, 1994, 1995 and 1996 are
derived from consolidated financial statements that have been audited by KPMG
LLP that are not included in this prospectus. The supplemental consolidated
statement of operations data for the year ended December 31, 1994 are derived
from unaudited consolidated financial statements that are not included in this
prospectus. The unaudited consolidated financial statements have been prepared
on substantially the same basis as the audited consolidated financial
statements and, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results of operations for these periods. Historical results
are not necessarily indicative of the results to be expected in the future, and
results of interim periods are not necessarily indicative of results for the
entire year.

   We are the successor to a Maryland corporation that was formed in August
1992 to provide computer consulting services. We began to offer Internet
connectivity services to enterprises in October 1994 and server hosting
services in late 1995. In August 1996, we opened our first dedicated Internet
Data Center and refocused our business strategy on providing Internet system
and network management solutions for enterprises with mission-critical Internet
operations.

   In the following tables and in this document, "EBITDA" represents earnings
(loss) before net interest expense, income taxes, depreciation, amortization
(including amortization of deferred stock compensation) and other noncash
charges. EBITDA should not be used as an alternative to operating loss or net
cash provided by (used for) operating activities, investing activities or
financing activities, each as measured under generally accepted accounting
principles. In addition, EBITDA may not be comparable to other similarly titled
information from other companies. However, our management believes that EBITDA
is an additional meaningful measure of performance and liquidity. With respect
to the captions entitled "Deficiency of earnings available to cover fixed
charges" and "Ratio of earnings to fixed charges," earnings consist of income
(loss) before provision for income taxes plus fixed charges. Fixed charges
consist of interest charges and amortization of debt expense and discount or
premium related to indebtedness, whether expensed or capitalized, and that
portion of rental expense we believe to be representative of interest.

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

   The following discussion of our financial condition and results of
operations should be read in conjunction with the supplemental consolidated
financial statements and the related notes included elsewhere in this
prospectus. This discussion contains forward-looking statements that involve
risks and uncertainties. Our actual results may differ materially from those
anticipated in these forward-looking statements. Factors that may cause such a
difference include those set forth under "Risk Factors".

Overview

   We are a leading provider of Internet system and network management
solutions and technology professional services for enterprises with mission-
critical Internet operations. Our solutions include Internet Data Centers,
network services, managed services and professional services that together
provide the high performance, scalability and expertise that enterprises need
to optimize Internet operations. We deliver our services from our
geographically distributed, state-of-the-art Internet Data Centers that are
connected through a high-performance Internet backbone network.

   We are the successor to a Maryland corporation that was formed in August
1992 to provide computer-consulting services. We began offering server hosting
and Internet connectivity services in late 1995, opened our first dedicated
Internet Data Center in August 1996 and introduced managed services in 1997 and
professional services in 1998. We have derived most of our revenues from
customers for whom we provide these services. Most of our Internet Data Center
customers initially purchase a subset of our service offerings to address
specific departmental or enterprise Internet computing needs, and many of these
customers purchase additional services as the scale and complexity of their
Internet operations increase. We sell our services under contracts that
typically have minimum terms of one year. Customers pay monthly fees for the
services utilized, as well as one-time fees for installation, certain
professional services and for equipment they purchase from us.

   We opened our first Internet Data Center in the Silicon Valley metropolitan
area in August 1996. Since that time, we have opened 16 additional domestic
Internet Data Centers in the metropolitan areas of New York (March 1997 and
September 1999), Silicon Valley (second site--August 1997; third site--June
1998; and fourth site June 1999), Seattle (September 1997 and June 1999), Los
Angeles (October 1997 and September 1999), Washington, D.C. (December 1997 and
May 1999), Boston (July 1998 and December 1999), Chicago (April 1999), Atlanta
(December 1999) and Austin, Texas (November 1999). In addition, we opened our
first Internet Data Center outside of the United States in London in June 1999.
In December 1999, we acquired Global OnLine Japan Co., Ltd. of Tokyo, Japan,
which has an Internet Data Center located in Tokyo. The building of Internet
Data Centers has required us to obtain substantial equity and debt financing.
See "Risk Factors--Our substantial leverage and debt service obligations
adversely affect our cash flow" and "--Liquidity and Capital Resources" below.

   In October 1998, we purchased the assets of Arca Systems, Inc. ("Arca"), a
provider of advanced network and system security consulting services. In
February 1999, we acquired American Information Systems, Inc. ("AIS"), a
regional provider of co-location, web hosting and professional services. In
July 1999, we acquired Cohesive Technology Solutions, Inc. ("Cohesive"), a
technology professional services organization with expertise in networking,
Internet-based applications and technology solutions. In November 1999, we
acquired Service Metrics, Inc., a provider of Internet monitoring applications
and services. In connection with the merger, we issued a total of approximately
7.0 million shares of our common stock and options for Exodus Common Stock in
exchange for all outstanding shares of Service Metrics common stock and
outstanding options we assumed. We will account for the Service Metrics merger
as a pooling of interests. In December 1999, we acquired Global OnLine Japan
Co., Ltd., an Internet solutions provider based in Tokyo. As a result, we
issued 415,000 shares of our common stock in exchange for 85% of the
outstanding shares of Global OnLine Japan. The transaction will be accounted
for as a purchase. In January 2000, we agreed to

                                       27
<PAGE>

acquire KeyLabs, Inc., a provider of e-business testing services based in Utah.
We expect the transaction, which will be accounted for as a purchase, to close
by the end of February 2000.

   We intend to expand domestically and internationally. Prior to building an
Internet Data Center in a new geographic region, we employ various means to
evaluate the market opportunity in a given location, including market research
on Internet usage statistics, the pre-selling of services into the proposed
market and analysis of specific financial criteria. We typically require at
least six months to select the appropriate location for an Internet Data
Center, construct the necessary facilities, install equipment and
telecommunications infrastructure, and hire the operations and sales personnel
needed to conduct business at that site. Expenditures related to an Internet
Data Center commence well before the Internet Data Center opens, and it takes
an extended period to approach break-even capacity utilization at each site. As
a result, we expect that individual Internet Data Centers will experience
losses for in excess of one year from the time they are opened. We experience
further losses from sales personnel hired to test market our services in
markets where there is no, and may never be an, Internet Data Center. As a
result, we expect to make investments in expanding our business rapidly into
new geographic regions which, while potentially increasing our revenues in the
long term, will lead to significant losses for the foreseeable future. See
"Risk Factors--Our rapid expansion produces a significant strain on our
business".

   Since we began to offer server hosting and Internet connectivity services in
1995, we have experienced operating losses and negative cash flows from
operations in each fiscal quarter and year. As of September 30, 1999, we had an
accumulated deficit of approximately $175.3 million. The revenue and income
potential of our business and market is unproven, and our limited operating
history makes an evaluation of our prospects and us difficult. We intend to
invest in new Internet Data Centers and other sites, product development, and
sales and marketing programs. We therefore believe that we will continue to
experience net losses on a quarterly and annual basis for the foreseeable
future. As a company in the new and rapidly evolving market for Internet system
and network management solutions, we encounter risks, expenses and difficulties
that affect our business and prospects. There can be no assurance that we will
achieve profitability on a quarterly or an annual basis or that we will sustain
profitability. See "Risk Factors--Our short operating history and heavy losses
make our business difficult to evaluate".

Results of Operations for the Years Ended December 31, 1996, 1997 and 1998 and
the Nine Months Ended September 30, 1998 and 1999

   The following table sets forth certain statement of operations data as a
percentage of total revenues for the years ended December 31, 1996, 1997 and
1998 and the nine-month periods ended September 30, 1998 and 1999. The
information for the years ended December 31, 1996, 1997 and 1998 has been
derived from our supplemental audited consolidated financial statements
included in this prospectus. The information for the nine-month periods ended
September 30, 1998 and 1999 has been derived from our supplemental unaudited
condensed consolidated financial statements included in this prospectus which,
in management's opinion, have been prepared on substantially the same basis as
the supplemental audited consolidated financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the financial information for the periods presented. This
information should be read in conjunction with the supplemental consolidated
financial statements and related notes included in this prospectus. The
operating results in any periods are not necessarily indicative of the results
to be expected for any future period.

 Revenues

   Our revenues consist of (1) monthly fees from customer use of Internet Data
Center sites, network services and managed services, including professional
services and use of equipment and software provided by us, (2) revenues from
sales of third-party equipment to customers and (3) fees for installation and
certain professional services. Currently, substantially all of our revenue is
derived from services. Revenues, other than installation fees, equipment sales
to customers and certain professional services, are generally billed and
recognized ratably over the term of the contract, which is generally one year.
Installation fees are typically recognized at the time the installation occurs,
and equipment revenues are typically recognized when the equipment is delivered
to the customer or placed into service at an Internet Data Center. We sell
third-party equipment to our customers as an accommodation to facilitate their
purchase of services. One-time professional service fees are typically
recognized when the services are rendered.

                                       29
<PAGE>

   Our service revenues increased 372% from $2.5 million in 1996 to $11.6
million in 1997 and increased an additional 330% to $49.8 million in 1998. This
growth in service revenues was primarily the result of opening our Internet
Data Centers, increases in the number of new customers, substantially all of
which were Internet Data Center customers, and increases in revenues from
existing customers. Equipment revenues increased 21% from $676,000 in 1996 to
$820,000 in 1997 and 257% to $2.9 million in 1998.

   Our revenues increased 345% to $140.8 million for the nine month period
ended September 30, 1999 from $31.6 million in the same period of the prior
year. This growth in revenues was the result of increases in the number of new
customers, substantially all of which were Internet Data Center customers,
increases in revenues from existing customers and revenue contributions from
Cohesive.

 Cost of Revenues

   Our cost of revenues is comprised of the costs for our backbone network and
local telecommunications loops, interconnections to other networks,
depreciation and amortization, salaries and benefits for our customer service
and operations personnel (customer service personnel, network engineers and
professional services personnel), rent, repairs and utilities related to our
Internet Data Centers and other sites and costs of third-party equipment sold
to customers.

   Cost of service revenues increased from $2.5 million in 1996 to $16.2
million in 1997 and to $59.3 million in 1998. Our cost of service revenues as a
percentage of revenues increased from 81% in 1996 to 131% in 1997 and declined
to 112% in 1998. The increases in cost of service revenues in absolute dollars
were due to increased costs associated with the build-out and operation of our
increasing number of Internet Data Centers, including increased costs for our
redundant backbone network and local telecommunications loops, depreciation,
salaries and benefits for our customer service and operations personnel, and
rent. The increase in cost of service revenues as a percentage of revenues from
1996 to 1997 reflects the timing of investments in Internet Data Centers and
network infrastructure relative to the growth in associated revenue. The
decrease in cost of service revenues as a percentage of revenues from 1997 to
1998 resulted from revenues from new and existing Internet Data Centers
increasing faster than related costs of revenues. Costs for our redundant
backbone network and local telecommunications loops increased by approximately
$3.8 million from 1996 to 1997 and by approximately $15.2 million from 1997 to
1998. Depreciation increased by approximately $3.0 million from 1996 to 1997
and by approximately $8.4 million from 1997 to 1998. Salaries and benefits for
our customer service and operations personnel increased by approximately $3.5
million from 1996 to 1997 and by approximately $6.7 million from 1997 to 1998.
Rent expense increased by approximately $945,000 from 1996 to 1997 and by
approximately $3.1 million from 1997 to 1998. Cost of equipment revenues
increased from $452,000 in 1996 to $640,000 in 1997 and to $2.3 million in
1998. Cost of equipment revenue in absolute dollars varies primarily as a
result of equipment revenues and cost of equipment revenues as a percentage of
revenues varies due to the mix of equipment purchased by customers.

   Cost of revenues increased 202% to $118.8 million for the nine month period
ended September 30, 1999 from $39.3 million in the same period of the prior
year. This increase in cost of revenues in absolute dollars was primarily the
result of costs associated with hiring additional employees, including
professional services employees hired in connection with our acquisition of
Cohesive, and consultants, increased traffic on our network and to other
networks, increased depreciation due to capital expenditures related to the
buildout and expansion of Internet Data Centers, increased rent, and increased
utilities and other costs related to the opening and expanding of Internet Data
Centers. Our cost of revenues as a percentage of revenues decreased to 84% for
the nine months ended September 30, 1999 from 124% for the same period of the
prior year. This decline was due primarily to an increase in revenue between
comparison periods. We expect that cost of revenues will continue to increase
in absolute dollars.

                                       30
<PAGE>

 Marketing and Sales

   Our marketing and sales expenses are comprised of salaries, commissions and
benefits for our marketing and sales personnel, printing and advertising costs,
public relations costs, consultants' fees and travel and entertainment
expenses.

   Our marketing and sales expenses increased from $2.7 million in 1996 to
$12.7 million in 1997 and to $29.0 million in 1998. These increases were
primarily the result of hiring additional marketing and sales personnel,
expanding marketing programs in connection with our expansion of our
operations, including the number and scope of our Internet system and network
management solutions, and in 1998, the charge of $525,000 associated with the
warrant for common stock issued to At Home Corporation. Salaries and benefits
for our sales and marketing personnel increased by approximately $6.1 million
from 1996 to 1997 and by approximately $10.5 million from 1997 to 1998, and
costs associated with tradeshows and advertising increased by approximately
$977,000 from 1996 to 1997 and approximately $114,000 from 1997 to 1998. The
increase in marketing and sales expenses as a percentage of revenues from 1996
to 1997 reflects the continued expansion of marketing and sales efforts prior
to the receipt of associated revenues. The decrease in marketing and sales as a
percentage of revenues from 1997 to 1998 was due to revenues growing faster
than marketing and sales expenses.

   Our marketing and sales expenses increased 106% to $42.5 million for the
nine month period ended September 30, 1999 from $20.6 million in the same
period of the prior year. The increase in absolute dollars was primarily the
result of increased compensation and related expenses associated with hiring
additional marketing and sales personnel, including employees hired in
connection with our acquisition of Cohesive, and increased advertising
expenses. Our marketing and sales expense as a percentage of revenues decreased
to 30% for the nine months ended September 30, 1999 from 65% for the same
period of the prior year. This decline was primarily due to our significant
increase in revenue between comparison periods. We expect that marketing and
sales expense will continue to increase in absolute dollars.

 General and Administrative

   Our general and administrative expenses are primarily comprised of salaries
and benefits for our administrative and management information systems
personnel, consulting fees and recruiting fees.

   Our general and administrative expenses increased from $1.1 million in 1996
to $6.0 million in 1997 and to $16.1 million in 1998. These increases were
primarily the result of increased compensation expenses associated with
additional hiring of general and administrative personnel, costs for
consultants and professional services providers, fees paid for recruiting and
amortization of deferred compensation. Salaries and benefits for general and
administrative personnel increased by approximately $2.0 million from 1996 to
1997 and by approximately $2.8 million from 1997 to 1998. Costs for consultants
and professional services providers increased by approximately $1.1 million
from 1996 to 1997 and by approximately $900,000 from 1997 to 1998. Recruiting
fees increased by approximately $968,000 from 1996 to 1997 and by approximately
$440,000 from 1997 to 1998. These increased expenses reflected our need for
additional general and administrative personnel to handle the expansion of our
operations. The amortization of deferred compensation included in general and
administrative expenses was $741,000 in 1997 and $597,000 in 1998, and there
was no such expense recorded in 1996. The increase in general and
administrative expenses as a percentage of revenues from 1996 to 1997 resulted
primarily from deferred compensation expenses in 1997. The decrease in general
and administrative expenses as a percentage of revenues from 1997 to 1998 was
due to revenues growing faster than general and administrative expenses.

   Our general and administrative expenses increased 164% to $25.5 million for
the nine month period ended September 30, 1999 from $9.7 million in the same
period of the prior year. The increase in absolute dollars was primarily the
result of increased compensation expenses associated with additional hiring of
general and administrative personnel, including employees hired in connection
with our acquisition of Cohesive, increased

                                       31
<PAGE>

rent and related expenses due to entering into additional operating leases
during the period, higher depreciation and increased recruiting expenses. Our
general and administrative expense as a percentage of revenues decreased to 18%
for the nine month period ended September 30, 1999 from 31% for the same period
of the prior year. This decline was primarily due to our significant increase
in revenue between comparison periods. We expect that general and
administrative expense will continue to increase in absolute dollars.

 Product Development

   Our product development expenses consist primarily of salaries and benefits
for our product development personnel and fees paid to consultants.

   Our product development expenses increased from $444,000 in 1996 to $1.6
million in 1997 and to $3.5 million in 1998. Our product development expenses
grew between the comparison periods primarily because of the addition of
product development personnel to support our expanded service offerings. The
decrease in product development expenses as a percentage of revenues from 1996
to 1998 resulted from revenues growing faster than product development
expenses.

   Our product development expenses increased 136% to $5.6 million for the nine
month period ended September 30, 1999 from $2.4 million in the same period of
the prior year. Our product development expenses grew primarily due to the
addition of product development personnel to support our expanded service
offerings. Our product development expense as a percentage of revenues
decreased to 4% for the nine months ended September 30, 1999 from 8% for the
same period of the prior year. This decline was due to our significant increase
in revenue between comparison periods. We expect that product development
expenses will continue to increase in absolute dollars.

 Amortization of Intangibles

   As part of our strategy to grow through acquisitions of complementary
businesses, we acquired the assets of Arca in October 1998, AIS in February
1999 and Cohesive in July 1999. In connection with those acquisitions, we have
recorded intangible assets related to goodwill, customer lists and workforce in
place. Amortization related to those intangibles was $4.7 million for the nine
month period ended September 30, 1999. These intangibles are being amortized on
a straight-line basis generally over 5 to 10 years.

 Restructuring Costs

   In August 1999, we announced plans to consolidate seven professional
services practice offices of Cohesive, which we acquired on July 27, 1999. We
determined that consolidation of these offices would maximize efficiencies of
the combined companies. This action is expected to be completed by December 31,
1999. In connection with the consolidation of these facilities, we recorded a
restructuring charge of $923,000 for the nine month period ended September 30,
1999. This charge includes approximately $689,000 for lease termination and
other related office closure costs and $234,000 in severance and other employee
benefits.

 Net Interest Expense

   Our net interest expense increased from $39,000 in 1996 to $506,000 in 1997
and to $9.7 million in 1998. The increase in net interest expense from 1996 to
1997 was primarily the result of substantially increased borrowings as we
entered into equipment loans and lease agreements to finance the construction
of our Internet Data Centers. The increase in net interest expense from 1997 to
1998 was primarily the result of interest expenses associated with our $200.0
million of senior notes which were issued July 1, 1998, substantially increased
borrowings as we entered into equipment loans and lease agreements to finance
the construction of our Internet Data Centers, and working capital lines of
credit to finance working capital for our operations.

   Our net interest expense increased to $20.0 million for the nine month
period ended September 30, 1999 from $5.1 million for the same period of the
prior year. The increase in net interest expense was primarily the result of
interest expense associated with our senior notes issued July 1, 1998 and June
22, 1999, and our convertible subordinated notes issued March 3, 1999.

                                       32
<PAGE>

   We expect that net interest expense will continue to increase as we enter
into additional equipment leases and loans, obtain additional borrowings and
long term debt and experience reduced interest income as a result of the
decline in our cash reserves to fund working capital and other uses.

 EBITDA

   Our loss before net interest expense, income taxes, depreciation,
amortization, including amortization of deferred stock compensation, and other
non-cash charges ("EBITDA") was $3.6 million in 1996, $20.3 million in 1997 and
$41.9 million in 1998. The increases in the level of EBITDA losses between the
comparison periods were primarily due to increased expenditures needed to
support our growth in operations, including salaries and benefits for
additional employees, network costs, rent, utilities and other costs related to
the increase in the number of our Internet Data Centers as well as increased
marketing and sales expenses, consulting fees and professional services.

   EBITDA loss was $28.0 million for the nine month period ended September 30,
1999 compared to $29.6 million for the same period of the prior year. The
decrease in the magnitude of EBITDA losses between the comparison periods was
primarily due to the significant increases in revenue over these periods offset
in part by increased compensation costs associated with the hiring of
additional employees during those time periods.

   Although EBITDA should not be used as an alternative to operating loss or
net cash provided by (used for) operating activities, investing activities or
financing activities, each as measured under generally accepted accounting
principles, our management believes that EBITDA is an additional meaningful
measure of performance and liquidity.

Liquidity and Capital Resources

   From inception through September 30, 1999, we have financed our operations
primarily through private sales of preferred stock, our initial public offering
of common stock in March 1998, our senior notes offerings in July 1998 and June
1999, our convertible subordinated notes offering in March 1999 and through
various types of equipment loans and lease lines and working capital lines of
credit. At September 30, 1999, our principal source of liquidity was
approximately $172.0 million in cash and cash equivalents. As of that date, we
also had equipment loans and lease lines of credit under which we could borrow
up to an additional aggregate of $1.2 million for purchases of equipment. As of
September 30, 1999, our total bank borrowings, equipment loans and lines of
credit facilities, capital lease obligations and senior and convertible notes
were $589.7 million. See Notes 4 and 6 of Notes to Supplemental Consolidated
Financial Statements.

   Since we began to offer server-hosting services in 1995, we have had
significant negative cash flows from operating activities. Net cash used for
operating activities for the nine months ended September 30, 1999 was $68.5
million, primarily due to net losses and increases in accounts receivable and
prepaid expenses and other assets, offset in part by increases in accounts
payable and depreciation and amortization. This compares to net cash used for
operating activities for the nine months ended September 30, 1998 of $31.6
million which was primarily due to net losses and an increase in accounts
receivable, offset in part by increases in accounts payable and accrued
interest payable and depreciation and amortization.

   Net cash used for investing activities for the nine months ended September
30, 1999 was $235.1 million primarily due to capital expenditures for the
continued construction of Internet Data Centers and the acquisitions of AIS and
Cohesive. This compares to net cash used for investing activities for the nine
months ended September 30, 1998 of $70.3 million which was due to capital
expenditures for the construction of Internet Data Centers and an increase in
restricted cash equivalents and investments.

   Net cash provided by financing activities for the nine month period ended
September 30, 1999 was $319.6 million, primarily due to the proceeds from our
issuance of $250.0 million of 5% Convertible Subordinated Notes and our
additional $75.0 million offering of 11 1/4% Senior Notes in June 1999. This

                                       33
<PAGE>

compares to net cash provided by financing activities for the nine months ended
September 30, 1998 of $283.3 million which was primarily due to our initial
public offering of common stock in March 1998 and our original $200.0 million
11 1/4% Senior Notes offering in July 1998.

   As of September 30, 1999, we had commitments under capital leases and under
noncancellable operating leases of $47.0 million and $260.3 million,
respectively, through 2012. In addition, in August 1999 we entered into
capacity purchase agreements with Global Crossing. The agreements provide for a
total potential outlay of approximately $105.0 million for fiber capacity and
related maintenance covering approximately 25 years. As of September 30, 1999
we had expended $7.0 million.

   We intend to make significant expenditures during the next 12 months
primarily for property and equipment, in particular equipment and construction
needed for existing and future Internet Data Centers, as well as office
equipment, computers and telephones. We expect to finance such capital
expenditures primarily through the remaining net proceeds from the 11 1/4%
Senior Notes and 5% Convertible Subordinated Notes and our 10 3/4% Senior Notes
and 4 3/4% Convertible Subordinated Notes issued in December 1999, existing and
future equipment loans and lease lines of credit, and issuances of additional
debt and other financing activities. We believe our working capital and capital
expenditure requirements over the next 12 months can be met with existing cash
and cash equivalents and short-term investments, cash from sales of services
and proceeds from debt financings and existing and future equipment financing
lines of credit. We may enter into additional equipment loans and capital
leases. We may also seek to raise additional funds through public or private
financing, strategic relationships or other arrangements. There can be no
assurance that we will be successful in generating sufficient cash flows from
operations or raising capital in sufficient amounts on terms acceptable to us.
See "Risk Factors--Our rapid expansion produces a significant strain on our
business".

 Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
establishes methods for accounting for derivative financial instruments and
hedging activities related to those instruments, as well as other hedging
activities. Because we do not currently hold any derivative instruments and do
not engage in hedging activities, we expect that the adoption of SFAS No. 133
will not have a material impact on our financial position, results of
operations or cash flows. We will be required to implement SFAS No. 133 for the
year ending December 31, 2001.

Quantitative and Qualitative Disclosures About Market Risk

 Interest Rate Risk

   Our exposure to market rate risk for changes in interest rates relates
primarily to our investment portfolio. We do not use derivative financial
instruments in our investment portfolio. We place our investments with high
quality issuers and, by policy, limit the amount of risk by investing primarily
in money market funds, United States Treasury Notes and certificates of
deposit. An increase or decrease in interest rates would not significantly
increase or decrease interest expense on debt obligations due to the fixed
nature of our debt obligations. We do not currently have any significant
foreign operations and thus are not currently materially exposed to foreign
currency fluctuations.

The Company

   Exodus Communications is a leading provider of Internet system and network
management solutions for enterprises with mission-critical Internet operations.
Our solutions include Internet Data Centers, network services, managed services
and professional services, which together provide the high performance,
scalability and expertise that enterprises need to optimize their complex
Internet operations. Exodus delivers its services from geographically
distributed, state-of-the-art Internet Data Centers that are connected through
a high-performance dedicated and redundant backbone network. Our tailored
solutions are designed to integrate with existing enterprise systems
architectures and to enable customers to outsource the monitoring,
administration and optimization of their equipment, applications and overall
Internet operations. As of September 30, 1999, we had more than 1,700
customers, including installed and uninstalled customers under contract, and
managed over 16,000 customer servers worldwide. Our customers represent a
variety of industries, ranging from Internet companies such as Lycos, Inc.,
eBay Inc., MSN Hotmail (a subsidiary of Microsoft Corporation), Yahoo!GeoCities
and Inktomi Corporation, to media companies such as MSNBC, USA Today
Information Network, SportsLine USA, Inc. and E-Online!, to major enterprise
companies such as Applied Materials and Storage Networks.

   Because Internet usage is growing rapidly, businesses are increasing the
breadth and depth of their Internet product and services offerings. These
Internet operations are mission-critical for Internet-centric businesses and
are becoming increasingly mission-critical for many enterprises. In order to
ensure the quality, reliability, availability and redundancy of these mission-
critical Internet operations, corporate IT departments must make substantial
investments in facilities, personnel, equipment and networks which must be
continuously upgraded to reflect changing technologies and must rapidly scale
as the enterprise grows. This recurring and significant investment is an
inefficient use of resources and, as a result, a significant need exists for
outsourcing arrangements that can increase performance, provide continuous
operation of Internet solutions and reduce Internet operating expenses. We
believe a significant opportunity exists for a highly focused company to
provide a combination of server hosting, Internet connectivity and managed and
professional services that will enable reliable, high performance of mission-
critical Internet operations.

   Exodus offers an integrated portfolio of solutions that provide customers
with a scalable, secure and high performance platform for the development,
deployment and proactive management of mission-critical Internet operations.
Our server hosting and Internet connectivity services are offered through our
Internet Data Centers' redundant backbone network of multiple high speed OC-3
and OC-12 lines, along with our public and private network interconnections. We
continue to upgrade our network in order to accommodate expected traffic
growth. Our managed services include performance monitoring, site management
reports, data backup, content delivery and management services, security
services and professional services. These services provide the foundation for
high performance, availability, scalability and reliability of customers'
Internet operations. In addition, we integrate best-of-breed technologies from
leading vendors with our industry expertise and proprietary technology.

   Our objective is to become the leading provider of Internet system and
network management solutions for enterprises with mission-critical Internet
operations. To achieve this objective, we intend to:

  .  Position Exodus as the leader in this market;

  .  Focus on enhancing systems and network management, Internet technology
     services and professional services;

  .  Accelerate our global expansion;

  .  Leverage our expertise to address new market opportunities; and

  .  Continue to establish strategic relationships for distribution and
     technology.

<PAGE>

   We began offering server hosting and Internet connectivity services in late
1995, opened our first dedicated Internet Data Center in August 1996, and
introduced managed services in 1997 and professional services in 1998. We
currently operate 17 domestic Internet Data Centers located in nine
metropolitan areas: Atlanta, Austin, Boston, Chicago, Los Angeles, New York,
Seattle, Silicon Valley and Washington, D.C. In addition, we opened our first
Internet Data Center outside of the United States in the London metropolitan
area in June 1999. In December 1999, we acquired Global OnLine Japan which has
an Internet Data Center in Tokyo, Japan. Our Internet Data Centers consist of
approximately 1,600,000 gross square feet.

   We recently expanded our solutions and services by acquiring providers of
Internet technologies--Arca, AIS, Cohesive Service Metrics and Global OnLine
Japan. In October 1998, we purchased Arca, a provider of advanced network and
system security consulting services. In February 1999, to accelerate our launch
into the Chicago metropolitan area, we acquired AIS, a regional provider of co-
location, Web hosting and professional services. In July 1999, we acquired
Cohesive for approximately $112.0 million in cash, Exodus common stock and the
assumption of Cohesive options. Cohesive is a technology professional services
organization with expertise in networking, Web applications and technology
solutions. In November 1999, we acquired Service Metrics, an Internet
monitoring applications and services company. In December 1999, we acquired
Global OnLine Japan, an Internet solutions provider. In addition, in January
2000, we agreed to acquire KeyLabs, Inc., a provider of e-business testing
services. See "Prospectus Summary--Recent Events".

Services

   Exodus' Internet solutions and services are designed to provide enterprises
with the high performance, scalability and expertise they need to optimize
their mission-critical Internet operations. We create tailored solutions for
our customers based on their unique business and technical requirements, and
modify the services as the customers' needs evolve. Our service offerings
include server hosting from within Internet Data Centers, network services,
managed services and professional services.

 Internet Data Centers--Server Hosting Facilities

   We deliver our services from geographically distributed, state-of-the-art
Internet Data Centers with uninterruptible power supply and back-up generators,
fire suppression, raised floors, HVAC, separate cooling zones, seismically
braced racks, 24x7 operations and high levels of physical security. In these
facilities, we support leading Internet hardware and software systems vendor
platforms, including those from Compaq Computer Corporation, Dell Computer
Corporation, Hewlett-Packard Company, IBM, Microsoft Corporation, Silicon
Graphics, Inc., Sun Microsystems, Inc. and The Santa Cruz Operation, Inc. This
multi-vendor flexibility enables the customer to retain complete control over
the technical solution and to integrate its Internet operations with its
existing IT technical architecture. Because mission-critical Internet
operations are typically very dynamic and often require immediate hardware and
software upgrades to maintain targeted service levels, customers have unlimited
24x7 access to the Internet Data Centers. Additional space and electrical power
can be added as needed, ensuring that the customer has access to additional
server hosting services.

   Based upon their technical requirements, customers can select from shared
rack facilities within common cage areas, highly secure cabinets, enclosed cage
facilities or vaults. Our server hosting facilities generally include dedicated
electrical power circuits to ensure that each customer's electrical power
requirements are met.

 Network Services--Internet Connectivity

   Exodus connects its Internet Data Centers through a high performance,
dedicated and redundant backbone network with multiple high speed OC-3 and OC-
12 lines, along with our extensive public and private network interconnections.
Our network services are designed to deliver the scalability, high availability
and performance required for high-volume, mission-critical Internet operations.
Since our customers' mission-critical Internet operations often experience
network traffic spikes due to promotions or events, we have a policy of
providing sufficient excess network capacity for our customers.

   To meet customers' requirements of near 100% availability, our network is
designed to minimize the likelihood of any single point of failure. Each
Internet Data Center has multiple physical fiber paths into the facility. We
maintain multiple network links from multiple vendors into each Internet Data
Center and regularly check that our fiber backbone is traversing physically
separated paths. Customers may also enhance their Internet site's availability
by physically duplicating their site at multiple Internet Data Centers, and
synchronizing applications and content through our private fiber backbone
network. This network architecture optimizes the availability of a customer's
site, even in the event of a link failure.

   Our network services are also designed to consistently deliver low-latency
and peak network performance. During the third quarter of 1999, our network
exchanged a sustained peak 5.6 gigabits per second volume of

                                       37
<PAGE>

traffic with the Internet. Our backbone engineering personnel continuously
monitor traffic patterns and congestion points throughout our network and at
our interconnection points, and dynamically reroute traffic flows to optimize
end-user response times. We also provide peak network performance by
maintaining a large number of direct public and private network peering
interconnections. Our network includes private peering interconnections with
approximately 200 ISPs worldwide.

 Managed Services

   We provide managed services to our customers, including detailed monitoring,
reporting and management tools to control their hardware, network, software and
application environments. Through our system and network management framework,
a customer can manage mission-critical Internet operations housed at our
Internet Data Centers as well as at the customer's site. We believe this
framework provides an important advantage to enterprises seeking to outsource a
portion of their Internet operations and to link the management of the
outsourced operations with in-house operations. Our proactive service
methodology focuses on identifying and resolving potential problems before they
affect an Internet site's availability or performance. Our sophisticated
Internet system and network management solutions enable us to identify and to
begin to resolve hardware, software, network and application problems,
frequently before the customer is even aware that a problem exists. We offer
the services summarized in the following chart:

Customers

   We have established a diversified base of customers in a wide range of
industries, including finance, entertainment, high technology, education,
healthcare and publishing. As of September 30, 1999, we had over 1,700
customers (including installed and uninstalled customers under contract). The
following is a representative list of our Internet Data Center customers. None
of these customers individually represented in excess of 10% of 1998 revenues
or revenues for the first nine months of 1999.

Sales and Marketing

   Our sales and marketing objective is to achieve broad market penetration
within our target market of enterprises that depend upon the Internet for
mission-critical operations. As of September 30, 1999, we had 316 employees
engaged in sales and marketing.

   We sell our services to enterprises directly through our sales force and
indirectly through our channel partners. We are actively seeking to increase
our sales and distribution capabilities and coverage in the United States and
to expand internationally as new Internet Data Centers are installed outside of
the United States, commencing with our Internet Data Center in London, England.
Currently, most of our sales are derived through the efforts of our direct
sales force.

 Sales Force

   Our sales force is organized into four distinct groups, consisting of field
sales, strategic accounts, channel sales and telesales, each of which is
further divided into geographical regions within the United States. There is
also a new sales organization in London that we began to staff in October 1998.
Systems engineers and project managers support our sales force, providing pre-
and post-sales support to ensure that customers' services are implemented
properly and efficiently.

 Channel Program

   Our channel program includes relationships with At Home Corporation, Compaq
Computer Corporation, Hewlett-Packard Company, Microsoft Corporation, Silicon
Graphics, Inc. and Sun Microsystems, Inc. The various levels of channel program
partner participation are summarized below:

  .  Solutions Integrators play a sales representative role for us, and
     receive a one-time payment, based on the monthly recurring charges from
     opportunities brought into us. They are typically consultants,
     independent Web developers, content developers, developers of small-to
     medium-sized applications and regional VARs.

  .  Alliance Partners market our services, and receive a monthly residual
     income for opportunities introduced to us. Alliance Partners are
     typically larger regional or national systems integrators, Web
     developers, hardware and software resellers, consulting organizations
     and ISPs.

                                       40
<PAGE>

  .  Technology Partners market software or hardware solutions, working
     together with us to offer superior services and innovative products.
     Through product promotions and bundled solutions, technology partners
     can offer their customers new value-added services and greater pricing
     incentives.

  .  Resellers market co-branded Exodus services. They commit to a certain
     volume level to resell as part of their application or niche-focused
     service offering to their customer base.

 Marketing

   Our marketing organization is responsible for product marketing management,
public relations and marketing communications. Product marketing management
includes defining the product roadmap and bringing to market the portfolio of
services and programs that will address customer needs. These activities
include product strategy and definition, pricing, competitive analysis, product
launches, channel program management and product lifecycle management. We
stimulate service demand and brand awareness for Exodus through a broad range
of marketing communications, public relations, advertising, as well as through
our Web site. Public relations focuses on cultivating industry analyst and
media relationships with the goal of securing broad media coverage and public
recognition of our leadership position in the market for Internet system and
network management solutions.

Customer Service

   We offer superior customer service by understanding the technical
requirements and business objectives of our customers and by fulfilling their
needs proactively on an individual basis. Working closely with our customers,
we optimize the performance of our customers' Internet operations, avoid
downtime, resolve problems that may arise, and make appropriate adjustments in
services as customer needs change over time. In December 1998, in order to
enhance our customer service delivery and increase operating efficiencies 24x7,
we launched a centralized response center which handles inbound calls,
monitoring, and problem resolution for our Internet Data Centers in the Silicon
Valley metropolitan area. Given the success of this program, in May 1999, we
centralized all response handling support for our domestic Internet Data
Centers in this Response Center. Partnering with our customers, we also solicit
feedback to ensure that we continue to offer the highest quality of service. We
use advanced software tools to aid in customer monitoring and service efforts.
Many of our customer service personnel have been specifically trained and
certified by the vendors of our software tools, including Sun Microsystems,
Inc., Microsoft Corporation, Oracle Corporation and Computer Associates.

   We also provide customer service and technical support during the
installation phase, including a transition team and project management support.
Our customer service continues after installation, through customer advocacy
representatives who are responsible for resolving customer problems.

   In addition, we provide system integration services between the customer's
Internet site and legacy systems. After installation, primary customer support
is coordinated through each Internet Data Center's Network Control Center.
These centers are operated 24x7 by engineers who monitor site and network
operations, and activate teams to solve problems that arise. To solve complex
problems, we draw on the collective expertise at all of our Internet Data
Centers, creating a nationwide engineering pool. Our customer service personnel
are also available to assist customers whose operations require specialized
procedures.

   We employ network engineers and systems administrators who work with
customers to design and maintain their Internet operations. Our network
engineers and system administrators are trained specialists who support Windows
NT, Solaris, Linux and other UNIX platforms. They are also trained to support
Cisco routers and switches. They also serve as the second level of support for
customer issues that cannot be resolved by the Network Control Center. We also
employ a group of backbone engineers who are accountable for designing and
operating the dynamic network that connects our Internet Data Centers. This
group constantly monitors the network design and effectiveness to optimize
performance for customers, rerouting and redesigning traffic as conditions
require.

                                       41
<PAGE>

   Our contracts with customers generally cover the provision of services by us
for a one-year period and may contain, among other things, various service
level warranties. These service agreements entered into prior to August 1997
typically included service level warranties which provided that, if we failed
to provide Internet Data Center services to a customer for more than 24
consecutive hours, a customer's account would be credited for the charges the
customer paid for services it did not receive during period affected. Between
August 1997 and July 1998, our service agreements typically included service
level warranties which provided that, if we fail to provide Internet Data
Center services to a customer for more than two consecutive hours, the
customer's account would be credited for one day of service and, if for more
than eight consecutive hours, one week of service, with each customer limited
to one credit per month. Since July 1998, our service agreements have typically
included service level warranties which provide that, if we fail to provide
Internet Data Center services to a customer for more than 15 minutes, the
customer's account would be credited for one day of service, up to a maximum of
seven days in any month. In addition, we provide additional credits for packet
loss and transmission latency. Certain customers have received more favorable
terms than those described above. To date, only a limited number of customers
have been entitled to these warranties to receive a credit for a period of free
service. As we did not open our first dedicated Internet Data Center until
August 1996, we have had Internet Data Center customers for only a short period
of time. Accordingly, we have had limited experience with customers continuing
to receive services after the initial term of their contract.

   As of September 30, 1999, we had 766 employees dedicated to customer
service, professional services and network engineering.

Network Design

   Our high performance server network is designed to provide the highest
possible availability and reliability for our customers' Internet operations.
The network comprises our Internet Data Centers that are interconnected by a
high-performance backbone network that is connected to the Internet through
public and private peering interconnections. Within each Internet Data Center,
a virtual LAN environment provides redundant, high-speed internal connectivity.

   Our Internet Data Centers are located near most of the major Internet
exchange points ("IXPs") and are connected to their local IXPs by multiple OC-3
and OC-12 lines, provisioned by local exchange carriers, such as Teleport
Communications Group Inc., MFS Communications Company, Inc., Brooks Fiber
Properties, Inc. and the Regional Bell Operating Companies. These links to the
local exchange points, combined with private exchanges with ISPs, connect the
customers' traffic to the Internet.

   In order to provide a high level of redundancy, performance and capacity,
along with real-time content replication or caching across our Internet Data
Centers, we have multiple OC-3 and OC-12 lines. We engineer our backbone with a
geographically diverse fiber path to provide high availability, even in the
event of a link failure. We regularly upgrade our network in order to
accommodate expected traffic growth. For customers with servers located at
multiple Internet Data Centers, we provide dynamic response time and load
balancing technologies for optimal routing of traffic.

   Within each Internet Data Center, we deploy a virtual LAN environment to
increase reliability and performance and to provide customers with redundant
connectivity to our backbone and the Internet, OC-3 and OC-12 lines are
strategically placed on different routers to avoid any single points of
failure. We also use a combination of public and private peering
interconnections to achieve fast and reliable delivery of content. We have
private and public interconnections with approximately 200 ISPs. We also have a
presence at each of the major U.S. IXPs.

   We will continue to work with ISPs to establish direct private
interconnections at each of our Internet Data Centers, thus enhancing content
delivery. Our broad combination of private and public interconnections provides
customers with the reliability and redundancy that they need to ensure their
content reaches its intended destination. We seek to provide significant
unutilized network capacity for our LAN, WAN and public and private peering
links to allow for spikes in demand or line outages.

Product Development

   Our product development group is accountable for evaluating and integrating
best-of-breed technologies to enhance our service offerings that support the
customers' mission-critical Internet operations. We are also developing
proprietary technologies that will be integrated with these best-of-breed
technologies. We believe that establishing relationships with technology
leaders enables us to leverage these enterprises' research and development
expertise. These relationships enable us to gain quicker access to innovative
technologies and thus provide more creative value-added solutions for our
customers. For example, we have worked very closely with Computer Associates to
develop certain of our management services using Computer Associates' Unicenter
TNG technology. See "Risk Factors--We depend on third-party equipment and
software suppliers".

   Our product development personnel have continued to develop strategic vendor
and technology relationships, such as the one with Computer Associates. Other
key partners include Checkpoint Software Technologies Limited, Cisco Systems,
Inc., Inktomi Corporation, Raptor Systems, Inc. and Sun Microsystems, Inc. To
the extent that we are unable to obtain the technology necessary to meet
customers' needs from a third party, we may develop the technology ourselves.
As of September 30, 1999, we employed 45 persons in product development.

   We incurred product development expenses of $444,000 in 1996, $1.6 million
in 1997, $3.5 million in 1998 and $5.6 million in the first nine months of
1999.

Competition

   Our market is intensely competitive. There are few substantial barriers to
entry, and we expect to face additional competition from existing competitors
and new market entrants in the future. Many companies have announced recently
that they intend to begin providing and/or greatly expanding their service
offerings to be competitive with our services. The principal competitive
factors in this market include:

  .  Internet system engineering and other technical expertise;

  .  customer service;

  .  network capability, reliability, quality of service and scalability;

  .  the variety of services offered;

  .  access to network resources, including circuits, equipment and
     interconnection capacity to other networks;

  .  broad geographic presence;

  .  price;

  .  the ability to maintain and expand distribution channels;

  .  brand name;

  .  the timing of introductions of new services;

  .  network security; and

  .  financial resources.

   There can be no assurance that we will have the resources or expertise to
compete successfully in the future. Our current and potential competitors in
the market include:

  .  providers of server hosting services;

  .  national, foreign and regional ISPs;

  .  global, regional and local telecommunications companies and Regional
     Bell Operating Companies;

                                       43
<PAGE>

  .  IT outsourcing firms; and

  .  other technology services and products companies.

   Many of our competitors have substantially greater resources, more
customers, longer operating histories, greater name recognition and more
established relationships in the industry. As a result, these competitors may
be able to develop and expand their network infrastructures and service
offerings more quickly, devote greater resources to the marketing and sale of
their products and adopt more aggressive pricing policies. In addition, these
competitors have entered and will likely continue to enter into business
relationships to provide additional services competitive with those we provide.

   Some of our competitors may be able to provide customers with additional
benefits in connection with the Internet system and network management
solutions, including reduced communications costs, which could reduce the
overall costs of their services relative to ours. We may not be able to offset
the effects of any price reductions. In addition, we believe our market is
likely to encounter consolidation in the near future, which could result in
increased price and other competition.

Employees

   As of September 30, 1999, Exodus had 1,315 employees, including 316
employees in sales and marketing, 45 employees in product development, 766
employees in customer service, professional services and network engineering
and 188 employees in finance and administration. We believe that our future
success will depend in part on our continued ability to attract, hire and
retain qualified personnel. The competition for personnel is intense, and there
can be no assurance that we will be able to identify, attract and retain
personnel in the future. None of our employees is represented by a labor union,
and management believes that our employee relations are good. See "Risk
Factors--We must manage growth effectively" and "Risk Factors--We depend on our
key personnel".

Properties

   Our executive offices are located in Santa Clara, California and consist of
approximately 150,000 square feet that are leased pursuant to an agreement that
expires in 2008. We lease the facilities for our current Internet Data Centers
in the following metropolitan areas and specific cities, which cover an
aggregate of approximately 1,600,000 gross square feet and expire in the years

                               OTHER INDEBTEDNESS

The 11 1/4% Senior Notes

   In July 1998 and July 1999, we issued an aggregate of $275.0 million of 11
1/4% Senior Notes pursuant to an indenture between us and Chase Manhattan Bank
and Trust Company, National Association, as trustee. The 11 1/4% Senior Notes
are unsecured obligations, and mature on July 1, 2008. Interest on the 11 1/4%
Senior Notes accrues at the rate of 11 1/4% per annum, payable semi-annually on
January 1 and July 1 of each year. We have placed in escrow enough cash to meet
the requirement of the first four interest payments due on the 11 1/4% Senior
Notes.

   The 11 1/4% Senior Notes will be redeemable at our option, in whole or in
part, at any time or from time to time, on or after July 1, 2003 at the
redemption prices set forth in the 11 1/4% Senior Notes indenture. In addition,
at any time prior to July 1, 2001, we may redeem up to 35% of the aggregate
principal amount of the 11 1/4% Senior Notes with the net proceeds of one or
more sales of certain types of our stock at a redemption price of 111.25%, plus
accrued and unpaid interest, if any, to the redemption date; provided that at
least 65% of the original principal amount of the 11 1/4% Senior Notes
initially issued remain outstanding. Upon a Change of Control, as defined in
the 11 1/4% Senior Notes indenture, we would be required to make an offer to
purchase the 11 1/4% Senior Notes at a purchase price equal to 101% of the
principal amount, plus accrued and unpaid interest, if any. The definition of
Change of Control in the 11 1/4% Senior Note Indenture is substantially similar
to the definition of Change of Control in the indenture governing our 10 3/4%
Senior Notes.

   The debt evidenced by the 11 1/4% Senior Notes ranks equally in right of
payment with all or our existing and future unsubordinated unsecured debt,
including the 10 3/4% Senior Notes, and senior in right of payment to all of
our existing and future subordinated debt, including the 4 3/4% Convertible
Subordinated Notes and the 5% Convertible Subordinated Notes.

   The 11 1/4% Senior Notes indenture restricts, among other things, our
ability to incur additional debt and the use of proceeds of such additional
debt, pay dividends or make certain other restricted payments, incur certain
liens to secure debt, or engage in merger transactions. There are significant
"carve-outs" and exceptions to these covenants.

The 5% Convertible Subordinated Notes

   In March 1999, we issued $250.0 million of 5% Convertible Subordinated Notes
due 2006 pursuant to an indenture between us and Chase Manhattan Bank and Trust
Company, National Association, as trustee. The 5% Convertible Subordinated
Notes are convertible into our common stock at a conversion rate of
87.5704 shares per $1,000 in principal amount of 5% Convertible Subordinated
Notes. The 5% Convertible Subordinated Notes are unsecured obligations, and
mature on March 15, 2006. Interest on the 5% Convertible Subordinated Notes
accrues at the rate of 5% per annum, payable semi-annually on March 15 and
September 15 of each year.

   The 5% Convertible Subordinated Notes will be redeemable at our option, in
whole or in part, at any time or from time to time, on or after March 20, 2001,
at the redemption prices set forth in the 5% Convertible Subordinated Notes
indenture; provided, however, that the 5% Convertible Subordinated Notes will
not be redeemable at our option on or after March 20, 2001 and before January
20, 2003 unless the last reported bid price for the Common Stock equals or
exceeds 140% of the conversion price for at least 20 trading days within a
period of 30 consecutive trading days ending within five trading days of the
call for redemption. Upon a Change of Control, as defined in the 5% Convertible
Subordinated Notes indenture, we would be required to make an offer to purchase
the 5% Convertible Subordinated Notes at a purchase price equal to 100% of the
principal amount, plus accrued and unpaid interest, if any. The definition of
Change of Control in the 5% Convertible Subordinated Notes Indenture differs in
a number of respects from the definition of Change of Control in the indenture
governing our 10 3/4% Senior Notes.

                                       49
<PAGE>

   The debt evidenced by the 5% Convertible Subordinated Notes is subordinated
in right of payment to all of our existing and future senior indebtedness
including the 11 1/4% Senior Notes and the 10 3/4% Notes and ranks equally in
right of payment to all of our existing and future subordinated debt. The
indenture governing the 10 3/4% senior notes will provide that the 10 3/4%
senior notes are "Designated Senior Indebtedness" as defined in the 5%
Convertible Subordinated Notes Indenture. This designation provides certain
additional rights to the holders of the 10 3/4% Senior Notes.

The 4 3/4% Convertible Subordinated Notes

   In December 1999, we issued $500.0 million of 4 3/4% Convertible
Subordinated Notes pursuant to an indenture between us and Chase Manhattan Bank
and Trust Company, National Association, as trustee. The 4 3/4% Convertible
Subordinated Notes are convertible into our common stock at a conversion rate
of 14.2034 shares per $1,000 in principal amount of 4 3/4% Convertible
Subordinated Notes. The 4 3/4% Convertible Subordinated Notes are unsecured
obligations, and mature on July 15, 2008. Interest on the 4 3/4% Convertible
Subordinated Notes accrues at the rate of 4 3/4% per annum, payable semi-
annually on January 15 and July 15 of each year, beginning July 15, 2000.

   The 4 3/4% Convertible Subordinated Notes will be redeemable at our option,
in whole or in part, at any time or from time to time, on or after January 20,
2002, at the redemption prices set for in the 4 3/4% Convertible Subordinated
Notes indenture; provided, however, that the 4 3/4% Convertible Subordinated
Notes will not be redeemable at our option on or after January 20, 2002 and
before January 15, 2004 unless the last reported bid price for the common stock
equals or exceeds 140% of the conversion price for at least 20 trading days
within a period of 30 consecutive trading days ending within five trading days
of the call for redemption. Upon a Change of Control, as defined in the 4 3/4%
Convertible Subordinated Notes indenture, we would be required to make an offer
to purchase the 4 3/4% Convertible Subordinated Notes at a purchase price equal
to 100% of the principal amount, plus accrued and unpaid interest, if any. The
definition of Change of Control in the 4 3/4% Convertible Subordinated Notes
indenture differs in a number of respects from the definition of Change of
Control in the indenture governing the 10 3/4% Senior Notes.

   The debt evidenced by the 4 3/4% Convertible Subordinated Notes is
subordinated in right of payment to all of our existing and future senior
indebtedness including the 11 1/4% Senior Notes and the 10 3/4% Senior Notes
and ranks equally in right of payment to all of our existing and future
subordinated indebtedness, including the 5% Convertible Subordinated Notes. The
indenture governing the 4 3/4% Convertible Subordinated Notes provides that the
10% Senior Notes are "Designated Senior Indebtedness" as defined in the 4 3/4%
Convertible Notes indenture. This designation provides certain additional
rights to the holders of the 10 3/4% Senior Notes.

   As of the date of this prospectus, $375.0 million aggregate principal amount
of the old dollar notes and (Euro)125.0 million aggregate principal amount of
the old euro notes are outstanding. This prospectus, together with the letters

obligation to accept old notes for exchange is subject to conditions as set

Registration Covenant; Exchange Offer

   Under our registration rights agreement with the Purchasers, we have agreed
to file with the Commission the exchange offer registration statement on the
appropriate form under the securities Act with respect to the new notes. Upon
the effectiveness of the exchange offer registration statement, we will offer
to the holders of the old notes who are able to make required representations
the opportunity to exchange their old notes for new notes. Alternatively, we
will file with the Commission a shelf registration statement to cover resales
of transfer restricted securities (as defined below) by the holders of old
notes who satisfy specific conditions relating to the provision of information
in connection with the shelf registration statement if:

  .  we are not permitted to consummate the exchange offer because it is not
     permitted by applicable law or Commission policy; or

     consummation of the exchange offer that:

    .  it is prohibited by law or Commission policy from participating in
       the exchange offer;

                                       51

       to the public without delivering a prospectus and the prospectus
       contained in the exchange offer registration statement is not
       appropriate or available for resales; or

    .  it is a broker-dealer and owns old notes acquired directly from us
       or one of our affiliates.

   We will use our best efforts to cause the applicable registration statement
to be declared effective as promptly as possible by the Commission.

   "Transfer restricted securities" means each old note until the earliest of:

  .  the date on which the old note has been exchanged by a person other than
     a broker-dealer for a new note in the exchange offer;

  .  following the exchange by a broker-dealer in the exchange offer of an
     old note for a new note, the date on which the new note is sold to a
     purchaser who received from the broker-dealer, on or prior to the date
     of the sale, a copy of the prospectus contained in the exchange offer
     registration statement;

     Securities Act and disposed of in accordance with the shelf registration
     statement; or

  .  the date on which the old note is distributed to the public pursuant to
     Rule 144 under the Securities Act.

   The registration rights agreement provides that:

  .  we will file and exchange offer registration statement with the
     Commission on or prior to 60 days after December 8, 1999, which is the
     date of the original issuance of the old notes;

  .  we will use our best efforts to have the exchange offer registration
     statement declared effective by the Commission on or prior to 150 days
     after December 8, 1999;

  .  unless the exchange offer would not be permitted by applicable law or
     Commission policy , we will commence the exchange offer and use our best
     efforts to issue, on or prior to 30 business days after the date on
     which the exchange offer registration statement was declared effective
     by the Commission, new notes in exchange for all old notes tendered in
     the exchange offer; and

  .  if obligated to file the shelf registration statement, we will use our
     best efforts to file the shelf registration statement with the
     Commission on or prior to 45 days after the filing obligations arises,
     but in no event less than 60 days after December 8, 1999, and to cause
     the shelf registration to be declared effective by the Commission on or
     prior to 90 days after this obligation arises, but in no event less than
     150 days after December 8, 1999.

   If a registration default (as defined below) occurs, we will pay liquidated
damages to each holder of transfer restricted securities, with respect to the
first 90-day period immediately following the occurrence of the first
registration default in and amount equal to $0.05 per week the registration
default continues per $1,000 principal amount of transfer restricted securities
held by the holder. The amount of the liquidated damages will increase by an
additional $0.05 per week that the registration default continues per
$1,000 principal amount of transfer restricted securities with respect to each
subsequent 90-day period until all registration defaults have been cured, up to
a maximum amount of liquidated damages for all registration defaults of $0.25
per week per $1,000 principal amount of transfer restricted securities. On each
interest payment date we will pay all accrued liquidated damages to the holders
of the old notes by wire transfer of immediately available funds or by federal
funds check and to holders of certificated securities by wire transfer to the
accounts specified by them or by mailing checks to their registered addresses
if no accounts have been specified. Following the cure of all registration
defaults, accrual of liquidated damages will cease.

exhibit to the registration statement of which this prospectus is a part.

Interest on Exchange Notes

   Each new note will bear interest from the most recent date to which interest
has been paid or duly provided for on the old note surrendered in exchange for
a new note, or, if no interest has been paid or duly provided for on the old
note, from December 8, 1999, the date of issuance of the old note. Holders of
the old notes whose old notes are accepted for exchange will not receive
accrued interest on the old notes for any period from and after the last
interest payment date to which interest has been paid or duly provided for on
the old notes prior to the original issue date of the new notes, or, if no
interest has been paid or duly provided for, will not receive any accrued
interest on the old notes. These holders will be deemed to have waived the
right to receive any interest on the old notes accrued from and after that
interest payment date, or, if no interest has been paid or fully provided for,
from and after December 8, 1999. Interest on the notes is payable semi-annually
in arrears on each June 15 and December 15.

   The method of delivery of old notes and the applicable letter of transmittal
and all other required documents to the applicable exchange agent is at the
election and risk of the holder. Instead of delivery by mail, it is recommended
that holders use an overnight or hand delivery service. In all cases,
sufficient time should be allowed to assure delivery to the applicable exchange
agent before the expiration date. No letter of transmittal or notes should be
sent to us. Holders may request their brokers, dealers, commercial banks, trust
companies or nominees to effect the above transactions for them.

                                       53
<PAGE>

   Any beneficial owner whose old notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct the
registered holder to tender on the beneficial owner's behalf.

   Signatures on a letter of transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an eligible institution (as defined below) unless
the old notes tendered:

  .  are signed by the registered holder, unless the holder has completed the
     box entitled "special exchange instructions" or "special delivery
     instructions" on the applicable letter of transmittal; or

  .  are tendered for the account of an eligible institution.

   In the event that signatures on a letter of transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, the guarantee
must be by a member firm of a registered national securities exchange or of the
National Association of Securities Dealers, Inc., a commercial bank or trust
company having an office or correspondent in the United States, or an "eligible
guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange
Act (an "eligible institution").

   If a letter of transmittal is signed by a person other than the registered
holder of any old notes listed on the letter of transmittal, the old notes must
be endorsed or accompanied by a properly completed bond power, signed by the
registered holder s the registered holder's name appears on the old notes, with
the signature guaranteed by an eligible institution.

   If a letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or other acting in a fiduciary or representative capacity, the
persons should so indicate when signing. Unless waived by us, evidenced
satisfactory to us of their authority to so act must be submitted with the
letter of transmittal.

   All questions as to the validity, form, eligibility, including time or
receipt, acceptance of tendered old notes and withdrawal of tendered old notes
will be determined by us in our sole discretion. This determination will be
final and binding. We reserve the absolute right to reject any and all old
notes that are not properly tendered or any old notes our acceptance of which
would, in the opinion of our counsel, be unlawful. We also reserve the right to
waive any defects, irregularities or conditions of tender as to particular old
notes. Our interpretation of the terms and conditions of the exchange offer,
including the instructions in the letters of transmittal, will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of old notes must be cured within the time period we
determine. Although we intend to notify holders of defects or irregularities
with respect to tenders of old notes, non of Exodus, the exchange agents or any
other person will incur any liability for failure to give this notification.
Tenders of old notes will not be deemed to have been made until defects or
irregularities have been cured or waived. Any old notes received by the
exchange agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the applicable
exchange agent to the tendering holders, unless otherwise provided in
applicable letter of transmittal, as soon as practicable following the
expiration date.

 Book-Entry Delivery Procedures

   Promptly after the date of this prospectus, the exchange agent for the old
dollar notes will establish accounts with respect to the old dollar notes at
DTC, and the exchange agent for the old euro notes will establish accounts with
respect to the old euro notes at each of Euroclear and Cedelbank (DTC,
Euroclear and Cedelbank are collectively referred to as the "book-entry
transfer facilities" and, individually as a "book-entry transfer facility") for
purposes of the exchange offer. Any financial institution that is a participant
in the applicable book-entry transfer facility's systems may make book-entry
delivery of the old notes by causing the applicable book-entry transfer
facility to transfer old notes into the applicable exchange agent's account at
the book-entry transfer facility in accordance with the book-entry transfer
facility's procedures for transfers. Timely book-entry delivery of old notes
pursuant to the exchange offer, however, requires receipt of a book-entry

                                       54
<PAGE>

confirmation prior to the expiration date. In addition, to receive new notes
for tendered old notes, the applicable letter of transmittal, or a mutually
signed facsimile, together with any required signature guarantees and any other
required documents, or an agent's message in connection with a book-entry
transfer, must, in any case, be delivered or transmitted to and received by the
applicable exchange agent at its address set forth under "--Exchange Agent"
below prior to the expiration date. Alternatively, the guaranteed delivery
procedures described below must be complied with. Tender will not be considered
made until the documents are received by the applicable exchange agent.
Delivery of documents to any of the book-entry transfer facilities does not
constitute delivery to the exchange agent.

 Tender of Existing Notes Held Through Book-Entry Transfer Facilities

   The exchange agents and each of the book-entry transfer facilities have
confirmed that the exchange offer is eligible for each of the book-entry
transfer facility's Automated Tender Offer Program, or ATOP. Accordingly,
participants in the applicable book-entry transfer facility's ATOP may, in lieu
of physically completing and signing the applicable letter of transmittal and
delivering it to the applicable exchange agent, electronically transmit their
acceptance of the exchange offer by causing the book-entry transfer facility to
transfer old notes to the applicable exchange agent in accordance with the
book-entry transfer facility's ATOP procedures for transfer. The book-entry
transfer facility will then send an agent's message to the applicable exchange
agent.

   The term "agent's message" means a message transmitted by a book-entry
transfer facility, received by exchange agent and forming party of the book-
entry confirmation, which states that:

  .  the book-entry transfer facility has received an expressed
     acknowledgement from a participant in its ATOP that is tendering old
     notes which are the subject of the book-entry conformation;

  .  the 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, the participant has received and agrees
     to be bound by the applicable notice of guaranteed delivery; and

  .  we may enforce the agreement against the participant.

 Guaranteed Delivery Procedure

   Holders who wish to tender their old notes and (1) whose old notes are not
immediately available, (2) who cannot deliver their old notes, the applicable
letter of transmittal or any other required documents to the applicable
exchange agent or (3) who cannot complete the procedures for book-entry
transfer, prior to the expiration date, may effect a tender if:

  .  the tender is made through an eligible institution;

  .  prior to the expiration date, the applicable agent receives from the
     eligible institution a properly completed and duly executed notice of
     guaranteed delivery by facsimile transmission, mail or hand delivery;

    .  setting forth the name and address of the holder;

    .  setting forth the certificate number(s) of the old notes and the
       principal amount of old notes tendered, stating that the tender is
       being made; and

    .  guaranteeing that, within three New York Stock Exchange trading days
       after the expiration date, the applicable letter of transmittal or
       facsimile together with the certificate(s) representing the old
       notes or a book-entry confirmation of the old notes into the
       applicable exchange agent's account at the applicable book-entry
       transfer facility and any other documents required by the applicable
       letter of transmittal, will be deposited by the eligible institution
       with the applicable exchange agent; and

                                       55
<PAGE>

  .  a properly completed and executed letter of transmittal for facsimile,
     as well as the certificate(s) representing all tendered old notes in
     proper form for transfer or a book-entry confirmation transfer of the
     old notes into the applicable exchange agent's account at the applicable
     book-entry transfer facility and all other documents required by the
     applicable letter of transmittal, are received by the applicable
     exchange agent within New York Stock Exchange trading days after the
     expiration date.

   Upon request to the applicable exchange agent, a notice of guaranteed
delivery will be sent to holders who wish to tender their old notes according
to the guaranteed delivery procedures set forth above.

Withdrawals of Tenders

   Except as otherwise provided in this prospectus, tenders of old notes may be
withdrawn at any time prior to 5:00 p.m., New York City time (10:00 p.m.,
London time), on the expiration date.

   To withdraw a tender of old notes in the exchange offer, a written or
facsimile transmission notice of withdrawal must be received by the applicable
exchange agent at the address set forth below prior to 5:00 p.m., New York City
time (10:00 p.m., London time), on the expiration date. Any notice of
withdrawal must:

  .  specify the name of the person having deposited the old notes to be
     withdrawn (the "depositor");

  .  identify the old notes to be withdrawn, including the certificates
     number(s) and principal amount of the old notes, or, in the case of old
     notes transferred by book-entry transfer, the name and number of the
     account at the applicable book-entry transfer facility to be credited;

  .  be signed by the holder in the same manner as the original signature on
     the letter of transmittal by which the old notes were tendered,
     including any required signature guarantees, or be accompanied by
     documents of transfer sufficient to have the trustee or other applicable
     registrar register transfer of the old notes into the name of the person
     withdrawing the tender; and

  .  specify the name in which any of the old notes are to be registered, if
     different from that of the depositor.

   All questions as to the validity, form and eligibility, including time or
receipt, of the notices will be determined by us. Our determination will be
final and binding on all parties. Any old notes so withdrawn will be deemed not
to have been validly tendered for purposes of the exchange offer and no new
notes will be issued in exchange unless the old notes so withdrawn are validly
retendered. Any old notes which have been tendered but which are not accepted
for exchange will be returned to their holder without cost to the holder as
soon as practicable after withdrawal, rejection of tender or termination of the
exchange offer. Properly withdrawn old notes may be retendered by following one
of the procedures described above under "--Procedures for Tendering Old Notes"
at any time prior to the expiration date.

Conditions to the Exchange Offer

   Notwithstanding any other terms of the exchange offer, we will not be
required to accept for exchange, or exchange new notes for, any old notes, and
may terminate the exchange offer before the acceptance of the old notes if, in
our sole judgment, the exchange offer would violate any law, statute, rule or
regulation or an interpretation thereof of the Staff of the Commission. If we
determine in our sole discretion that this condition is not satisfied, we may:

  .  refuse to accept any old notes and return all tendered old notes to the
     tendering holders;

  .  extend the exchange offer and retain all old notes tendered prior to the
     expiration date, subject, however, to the rights of holders to withdraw
     the old notes (see "--Withdrawals of Tender"); or

  .  waive the unsatisfied conditions with respect to the exchange offer and
     accept all validly tendered old notes which have not been withdrawn. If
     the waiver constitutes a material change to the exchange

                                       56
<PAGE>

     offer, we will promptly disclose the waiver by means of a prospectus
     supplement that will be distributed to the registered holders, and we
     will extend the exchange offer for a period of five to ten business
     days, depending upon the significance of the waiver and the manner of
     disclosure to the registered holders, if the exchange offer would
     otherwise expire during that five to ten business-day period.

Exchange Agent

   Chase Manhattan Bank & Trust Company, National Association has been
appointed as the exchange agent for the exchange offer of the old dollar
notes. Chase Manhattan Bank London has been appointed as the exchange agent
for the exchange offer of the euro notes. All executed letters of transmittal
should be directed to the applicable exchange agent at the address set forth
below. Questions and requests for assistance, requests for additional copies
of this prospectus or of the letter of transmittal and requests for notices of
guaranteed delivery should be directed to the applicable exchange agent,
addressed as follows:

   If to the Chase Manhattan Bank & Trust Company, National Association:

   By mail or by hand:

   Chase Manhattan Bank & Trust Company, National Association, Exchange Agent
   Suite 2725
   101 California Street
   San Francisco, California 94111

   By Facsimile:
   (415) 693-8850

   (415) 954-9581

   If to Chase Manhattan Bank London:

   By mail or by hand:

  Chase Manhattan Bank London

  9 Thomas More Street
  London, E1 9YT, UK

   Delivery of a letter of transmittal to an address other than that for the
applicable exchange agent as set forth above or transmission of instructions
via facsimile other than as set forth above does not constitute a valid
delivery of a letter of transmittal.

Fees and Expenses

   We will not make any payment to brokers, dealers or other soliciting
acceptances of the exchange offer.

Transfer Taxes

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

Accounting Treatment

   The new notes will be recorded at the same carrying value as the old notes.
This is the aggregate principal amount of the old notes, as reflected in our
accounting records on the date of exchange. Accordingly, no gain or loss for
accounting purposes will be recognized in connection with the exchange offer.
The expenses of the exchange offer will be amortized over the term of the new
notes.

                                      57
<PAGE>

Appraisal Rights

   Holders of old notes will not have dissenters' rights or appraisal rights in
connection with the exchange offer.

Resale of New Notes

   The new notes are being offered to satisfy our obligations contained in the
registration rights agreement. We are making the exchange offer in reliance on
the position of the Staff of the Commission as set forth in the Exxon Capital
No-Action Letter, the Morgan Stanley No-Action Letter, the Shearman & Sterling
No-Action Letter, and other interpretive letters addressed to third parties in
other transactions. However, we have not sought our own interpretive letter
addressing these matters and there can be no assurance that the Staff would
make a similar determination with respect to the exchange offer as it has in
those interpretive letters to third parties. Based on these interpretations by
the Staff, and subject to the two immediately following sentences, we believe
that new notes issued pursuant to this exchange offer in exchange for old notes
may be offered for resale, resold and otherwise transferred by holders, other
than a holder who is a broker-dealer, without further compliance with the
registration and prospectus delivery requirements of the Securities Act,
provided that:

  .  the new notes are acquired in the ordinary course of the holder's
     business; and

  .  the holder is not participating, and has no arrangement or understanding
     with any person to participate, in a distribution within the meaning of
     the Securities Act of the new notes.

   However, any holder who:

  .  is an "affiliate" of us, within the meaning of Rule 405 under the
     Securities Act;

  .  does not acquire new notes in the ordinary course of its business;

  .  intends to participate in the exchange offer for the purpose of
     distributing new notes; or

  .  is a broker-dealer who purchased old notes directly from us,

will not be able to rely on the interpretations of the Staff set forth in the
above-mentioned interpretive letters; will not be permitted or entitled to
tender old notes in the exchange offer; and must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any sale or other transfer of old notes unless the sale is made pursuant to an
exemption from those requirements.

   In addition, as described below, if any broker-dealer holds old notes
acquired for its own account as a result of market-making or other trading
activities and exchanges the old notes for new notes (a "participating broker-
dealer"), the participating broker-dealer may be deemed to be a statutory
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resales of new notes. See "Plan of Distribution."

   Each holder who wishes to exchange old notes for new notes in the exchange
offer will be required to represent that:

  .  it is not an affiliate of us;

  .  any new notes to be received by it are being acquired in the ordinary
     course of its business; and

  .  it has no arrangement or understanding with any person to participate in
     a distribution, within the meaning of the Securities Act, of new notes.

   Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must:

  .  acknowledge that it acquired the old notes for its own account as a
     result of market-making activities or other trading activities, and not
     directly from us, and


                                       58
<PAGE>

  .  must agree that it will deliver a prospectus meeting the requirements of
     the Securities Act in connection with any resale of new notes.

   The letters of transmittal state that by so acknowledging and by delivering
a prospectus, a participating broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. Based on the
position taken by the Staff in the interpretive letters referred to above, we
believe that participating broker-dealers may fulfill their prospectus delivery
requirements with respect to the new notes received upon exchange of old notes
with a prospectus meeting the requirements of the Securities Act, which may be
the prospectus prepared for an exchange offer so long as it contains a
description of the plan of distribution with respect to the resale of new
notes. Accordingly, this prospectus, as it may be amended or supplemented from
time to time, may be used by a participating broker-dealer during the period
referred to below in connection with the resales of new notes received in
exchange for old notes where the old notes were acquired by the participating
broker-dealer for its own account as a result of market-making or other trading
activities.

   Subject to provisions set forth in the registration rights agreement, we
shall use our best efforts to:

  .  keep the exchange offer registration statement continuously effective,
     supplemented and amended to the extent necessary to ensure that it is
     available for sales of new notes by participating broker-dealers; and

  .  ensure that the exchange offer registration statement conforms with the
     requirements of the Securities Act and the policies, rules and
     regulations of the Commission as announced from time to time, for a
     period ending upon the earlier of 180 days after the exchange offer has
     been completed or at the time the participating broker-dealers no longer
     own any transfer restricted securities. See "Plan of Distribution."

   Any participating broker-dealer who is an affiliate of us may not rely on
the interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.

   Each participating broker-dealer who surrenders old notes pursuant to the
exchange offer will be deemed to have agreed, by execution of a letter of
transmittal, that, upon receipt of notice from us of the occurrence of any
event or the discovery of any fact which makes any statement contained or
incorporated by reference in this prospectus untrue in any material respect or
which causes this prospectus to omit to state a material fact necessary in
order to make the statements contained or incorporated by reference herein, in
light of the circumstances under which they were made, not misleading or of the
occurrence of other events specified in the registration rights agreement, the
participating broker-dealer will suspend the sale of new notes pursuant to this
prospectus until we have amended or supplemented this prospectus to correct the
misstatement or omission and have furnished copies of the amended or
supplemented prospectus to the participating broker-dealer or we have given
notice that the sale of the new notes may be resumed, as the case may be.

Consequences of Failure to Exchange Old Notes

   Any old notes tendered and exchanged in the exchange offer will reduce the
aggregate principal amount of old notes outstanding. Following the consummation
of the exchange offer, holders who did not tender their old notes generally
will not have any further registration rights under the registration rights
agreement, and these old notes will continue to be subject to restrictions on
transfer. Accordingly, the liquidity of the market for the old notes could be
adversely affected. The old dollar notes are currently eligible for sale under
Rule 144A through the Portal Market and the old euro notes are in the process
of being listed on the Luxembourg Stock Exchange. Application is expected to be
made for listing the new euro notes on the Luxembourg Stock Exchange. We cannot
assure you that we will be successful in these listings or of when the listings
will be complete. Because we anticipate that most holders will elect to
exchange their old notes for new notes due to the absence of most restrictions
on the resale of new notes, anticipate that the liquidity of the market for any
old notes remaining outstanding after the exchange offer may be substantially
limited.

                                       59
<PAGE>

   As a result of the making of the exchange offer, we will have fulfilled our
obligations under the registration rights agreement, and holders who do not
tender their old notes generally will not have any further registration rights
or rights to receive liquidated damages specified in the registration rights
agreement for our failure to register the new notes.

   The old notes that are not exchanged for new notes will remain restricted
securities. Accordingly, the old notes may be resold only:

  .  to Exodus or one of its subsidiaries;

  .  to a qualified institutional buyer;

  .  to an institutional accredited investor;

  .  to a party outside the United States under Regulation S under the
     Securities Act;

  .  under an exemption from registration provided by Rule 144 under the
     Securities Act; or

  .  under an effective registration statement.

<PAGE>

                              DESCRIPTION OF NOTES

General

   The old notes were and the new notes will be issued under an indenture dated
December 1, 1999 between us and Chase Manhattan Bank and Trust Company,
National Association, as trustee. The term "notes" refers to the old notes and
the new notes. The statements under this caption relating to the notes and the
indenture are summaries and are not intended to be complete. In addition, they
are subject to, and are qualified by the actual provisions of the indenture.
The indenture is by its terms subject to and governed by the Trust Indenture
Act of 1939. If we make reference to particular provisions of the indenture or
to defined terms not defined in this prospectus, the provisions or defined
terms are incorporated by reference to this prospectus. You may obtain copies
of the indenture and the registration rights agreement referred to below are
available for review at the corporate office of the trustee or from us upon
request.

   The notes are our senior unsecured obligations and:

  .  rank equally in right of payment with our existing and future senior
     unsecured debt, including $275.0 million in principal amount of our 11
     1/4% Senior Notes due 2008;

  .  are senior in right of payment to our existing and future subordinated
     debt, including $250.0 million principal amount of our 5% Convertible
     Subordinated Notes due March 15, 2006 and $500.0 million principal
     amount of our 4 3/4% Convertible Subordinated Notes due July 15, 2008;
     and

  .  are effectively subordinated to our secured indebtedness to the extent
     of the value of the assets securing the indebtedness; and to any
     liabilities of our subsidiaries.

   Any right we have to receive assets of our subsidiaries upon their
liquidation or reorganization will be effectively subordinated to the claims of
that subsidiary's creditors, including trade creditors, except to the extent
that we are recognized as a creditor of the subsidiary, in which case our
claims would still be subordinate to any security in the assets of the
subsidiary and any debt of the subsidiary senior to that held by us. See "Risk
Factors--The notes are effectively subordinated to our secured indebtedness and
the liabilities of our subsidiaries."

   Assuming that we had completed the offering of the old notes and $500.0
million principal amount of our 4 3/4% Convertible Subordinated Notes due July
15, 2008 as of September 30, 1999, we would have

  .  approximately $275.0 million of debt outstanding which ranks equally in
     right of payment with the notes;

  .  approximately $750.0 million of debt outstanding which is subordinate in
     right of payment to the notes; and

  .  approximately $79.1 million of outstanding secured debt and liabilities
     of our subsidiaries, including trade payables, which effectively rank
     senior to the notes.

   The indenture limits our ability and the ability of our subsidiaries to
incur additional indebtedness. However, these limitations are subject to a
number of exceptions, and we and our subsidiaries may incur significant
additional indebtedness in the future, including indebtedness to which the
holders of the notes would be effectively subordinated.

   Under various circumstances, we will be able to designate current or future
subsidiaries as Unrestricted Subsidiaries, which will not be subject to many of
the restrictive covenants discussed in the indenture.

   The notes are not entitled to any security and are not entitled to the
benefit of any guarantees except under the circumstances described under "--
Covenants--Limitation on Guarantees of Issuer Debt by Restricted Subsidiaries."

                                       61
<PAGE>

   The euro notes and the dollar notes will generally be treated for purposes
of the indenture as a single series of securities ranking equally with each
other. Various actions taken on a "pro rata" basis under the indenture will be
taken in the manner described below.

   The aggregate principal amount, or any portion thereof, of the notes, at any
date of determination, shall be the sum of (1) the U.S. Dollar Equivalent at
such date of determination, of the principal amount, or portion thereof, as the
case may be, of the euro notes and (2) the principal amount, or portion
thereof, as the case may be, of the dollar notes at such date of determination.
With respect to any matter requiring consent, waiver, approval or other action
of the holders of a specified percentage of the principal amount of the notes,
such percentage shall be calculated, on the relevant date of determination, by
dividing (a) the principal amount, as of such date, of notes the holders of
which have so consented by (b) the aggregate principal amount, as of such date,
of the notes then outstanding, in each case, as determined in accordance with
the preceding sentence.

Principal, Interest and Maturity

   The notes will mature on December 15, 2009. The dollar notes will be limited
to $375.0 million (together with $100.0 million of Additional Notes) and the
euro notes will be limited to (Euro)125.0 million. However, we may issue an
additional $100.0 million of dollar notes and (Euro)100.0 million of euro notes
(above and beyond the $100.0 million of Additional Notes) under the indenture
under specific circumstances. Each note bears interest at 10 3/4% per annum
from December 8, 1999 or from the most recent interest payment date to which
interest has been paid, payable semiannually on June 15 and December 15 of each
year, commencing June 15, 2000. We will make each interest payment to the
person in whose name the note, or any predecessor note, is registered at the
close of business on the June 1 and December 1 immediately preceding the
interest payment date. Interest is computed on the basis of a 360-day year of
12 30-day months.

   We have agreed to file and cause to become effective a registration
statement relating to an exchange offer for the old notes, or, in lieu thereof,
to file and cause to become effective a resale shelf registration for the old
notes. If the exchange offer or shelf registration statement is not filed or is
not declared effective, or if the exchange offer is not consummated, within the
time periods set forth in the registration rights agreement, special interest
will accrue and be payable on the old notes. See "Registration Covenant;
Exchange Offer" above.

   Principal, premium, if any, interest and liquidated damages, if any, on the
dollar notes will be payable in U.S. dollars, and the dollar notes may be
presented for registration of transfer and exchange, at the office or agency of
the exchange agent maintained for that purpose in the Borough of Manhattan, The
City of New York. Principal, premium, if any, interest and liquidated damages,
if any, on the euro notes will be payable in euros, and the euro notes may be
presented for registration of transfer and exchange, at the office or agency of
the registrar or exchange agent maintained for that purpose in Luxembourg or
London, as the case may be. However, at our option, payment of interest on the
notes may be made by check mailed to the address of the person entitled thereto
as it appears in the Note Register.

   You will not pay a service charge for any registration of transfer or
exchange of notes, but we may require payment of a sum sufficient to cover any
related tax or other governmental charge.

Issuance of Additional Notes

   We will have the right to issue dollar denominated Additional Notes on or
prior to December 8, 2000, in an aggregate principal amount not to exceed
$100.0 million, upon written notice to the trustee.

Form, Denomination, Book-Entry Procedures and Transfer

   The old notes were initially issued in the form of global notes. The global
notes and any notes issued in exchange thereof, including beneficial interests
in the restricted global notes, are subject to certain restrictions

                                       62
<PAGE>

on transfer set forth therein and in the indenture. Euro notes sold to
qualified institutional buyers pursuant to Rule 144A of the Securities Act were
initially represented by one global note (the "Euro U.S. Global Note") and euro
notes sold outside the United States pursuant to Regulation S under the
Securities Act were initially represented by one global note (the "Euro
International Global Note" and, together with the Euro U.S. Global Note, the
"Euro Global Notes"). We deposited Euro International Global Notes with a
common depositary for Euroclear and Cedelbank, or its nominee and the Euro U.S.
Global Note with a depositary for Euroclear. Investors may hold their interests
in the Euro International Global Notes directly through Euroclear or Cedelbank
or indirectly through organizations which are participants in Euroclear or
Cedelbank and the Euro U.S. Global Note through Euroclear or indirectly through
organizations which are participants in Euroclear.

   Dollar notes sold to qualified institutional buyers pursuant to Rule 144A of
the Securities Act were initially represented by one or more global notes (the
"Dollar U.S. Global Note") and dollar notes sold outside the United States
pursuant to Regulation S under the Securities Act were initially represented by
one or more global notes (the "Dollar International Global Note" and, together
with the Dollar U.S. Global Note, the "Dollar Global Notes"). The Dollar Global
Notes were deposited with the trustee as custodian for DTC (together with
Euroclear and Cedelbank, the "Depositaries") and registered in the name of Cede
& Co., as nominee of DTC. Prior to January 17, 2000, interests in the Dollar
International Global Notes could be held only through Euroclear and Cedelbank.
Investor may hold their interests in the Dollar International Global Notes
directly through Euroclear or Cedelbank, or indirectly through organizations
which are participants in such systems. Euroclear and Cedelbank hold interests
in the Dollar International Global Note in their respective names on the books
of DTC on behalf of their participants. Beginning January 17, 2000, ownership
interests in the Dollar International Global Notes could also be held through
organizations other than Cedelbank or Euroclear that are participants in DTC.
Dollar Book-Entry Interests will be shown on, and transfers thereof will be
effected only through, records maintained in book-entry form by DTC and its
participants.

   Book-entry interests in the dollar notes are held by DTC (the "Dollar Book-
Entry Interests") and book-entry interests in the euro notes are held by
Euroclear or Cedelbank in the case of euro notes sold outside of the U.S. in
reliance on Regulation S and Euroclear in the case of euro notes sold within
the U.S. to qualified institutional buyers (the "Euro Book-Entry Interests"
and, collectively with the Dollar Book-Entry Interests, the "Book-Entry
Interests"). Book-Entry Interests are not held in definitive from. Instead,
DTC, Euroclear and/or Cedelbank credit on their respective book-entry
registration and transfer systems a participant's account with the interest
beneficially owned by such participant. The laws of some jurisdictions,
including some states of the United States, may require that purchasers of
securities take physical delivery of securities in definitive form. The
foregoing limitations may impair the ability to own, transfer or pledge Book-
Entry Interests. While the notes are in global form, holders of Book-Entry
Interests will not be considered the owners or "holders" of notes for any
purpose, including with respect to the giving of any directions, instructions
or approvals to the trustee under the indenture.

   Owners of Book-Entry Interests may receive notes in definitive registered
form ("Definitive Registered Notes") in specified circumstances described in
the indenture.

   In such an event, the registrars for the notes will issue notes in
definitive registered form ("Definitive Registered Notes"), registered in the
name or names and issued in any approved denominations, requested by or on
behalf of DTC, Euroclear and/or Cedelbank, as applicable (in accordance with
their respective customary procedures and based upon directions received from
participants reflecting the beneficial ownership of Book-Entry Interests) and
will bear the restrictive legend currently set forth on the Dollar Global Notes
and the Euro Global Notes, unless that legend is not required by the indenture
or applicable law. Principal of, premium, if any, and interest on any
Definitive Registered Notes will be payable at the corporate trust office or
agency of the relevant paying agent maintained in New York City, London or
Luxembourg for such purpose.

   If Definitive Registered Notes are issued and these euro notes are listed on
the Luxembourg Stock Exchange, transfers of euro notes will have to be cleared
through a clearing system or a method approved by the rules and regulations of
the Luxembourg Stock Exchange in order to continue to be listed on the
Luxembourg Stock Exchange.

                                       63
<PAGE>

   To the extent permitted by law, we, the trustee and the registrars shall be
entitled to treat the registered holder of any note as the absolute owner
thereof.

   Holders of the Book-Entry Interests may incur fees normally payable in
respect of the maintenance and operation of accounts in DTC, Euroclear and/or
Cedelbank.

   Neither we, the trustee nor any registrar of notes, will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of Book-Entry Interests or for maintaining,
supervising or reviewing any records of DTC, Euroclear or Cedelbank relating to
the notes.

   The global notes may be transferred only to a successor to the relevant
Depositary.

   Book-Entry Interests in the notes will be subject to certain restrictions on
transfer and certification requirements.

   All transfer of Book-Entry Interests between participants in DTC,
participants in Euroclear or participants in Cedelbank will be effected by DTC,
Euroclear or Cedelbank pursuant to customary procedures and subject to the
applicable rules and procedures established by DTC, Euroclear or Cedelbank and
their respective participants.

   Subject to the foregoing, a Book-Entry Interest in one of the global notes
may be transferred to a person who takes delivery thereof in the form of a
Book-Entry Interest in another of the global notes of the same currency by
means of an instruction originated through DTC, Euroclear or Cedelbank, as
applicable. Any Book-Entry Interest that is so transferred will, upon transfer,
cease to be a Book-Entry Interest in the first-mentioned global note and become
a Book-Entry Interest in the other global note and will thereafter be subject
to all transfer restrictions, if any and other procedures applicable to Book-
Entry Interests in such other global note for as long as it remains such a
Book-Entry Interest. In connection with the transfer, appropriate adjustments
will be made to reflect a decrease in the principal amount at maturity of the
first-mentioned global note and a corresponding increase in the principal
amount at maturity of the other global note, as applicable. The indenture
contains limits on the ability of holders to transfer interests from Dollar
U.S. Global Notes to Dollar International Global Notes and from Euro U.S.
Global Notes to Euro International Global Notes.

   Euro notes issued as Definitive Registered Notes may be transferred, upon
surrender for registration of transfer of such note at the office or agency
maintained for such purpose in New York City, London or Luxembourg, in whole or
in part, in denominations of (Euro)1,000 in principal amount or integral
multiples of (Euro)1,000 and dollar notes issued as Definitive Registered Notes
may be transferred, upon surrender for registration of transfer of such note at
the office or agency maintained for such purpose in New York City, in whole or
in part, in denominations of $1,000 in principal amount or integral multiples
of $1,000.

Optional Redemption

   Except as described below, the notes will not be redeemable at our option
prior to December 15, 2004.

   The notes are subject to redemption, at our option, in whole or in part, at
any time on or after December 15, 2004 and prior to maturity, upon not less
than 30 nor more than 60 days' notice. The notice must be mailed to each
holder of notes to be redeemed at each holder's address appearing in the Note
Register. The dollar notes are redeemable in amounts of $1,000 or an integral
multiple of $1,000 and the euro notes are redeemable in amounts of (Euro)1,000
or an integral multiple of (Euro)1,000, as the case may be. Redemption would
be made at the following prices, expressed as percentages of the principal
amount if redeemed during the 12-month period beginning December 15 of the
years indicated below. Holders will also receive accrued and unpaid interest
and liquidated damages, if any, to but excluding the redemption date, subject
to the right of holders of record on the immediately preceding record date to
receive interest due on an interest payment date that is on or prior to the
redemption date.

   2007 and thereafter...............................................  100.000%
</TABLE>

   In addition, at any time prior to December 15, 2002, we may redeem up to
35% of the aggregate outstanding principal amount of the dollar notes and up
to 35% of the aggregate outstanding principal amount of the euro notes with
the Net Cash Proceeds of one or more sales of Capital Stock, other than
Disqualified Stock, at a redemption price equal to 110.75% of the aggregate
principal amount of the notes, plus accrued and unpaid interest and liquidated
damages, if any, to the date of redemption. However, at least 65% of the
original principal amount of the dollar notes and 65% of the original
principal amount of the euro notes must remain outstanding immediately
following the redemption. In order to effect the redemption, we must mail a
notice of redemption no later than 45 days after the related sale of Capital
Stock and must consummate the redemption within 60 days of the closing of the
sale of Capital Stock.

   If less than all the notes are to be redeemed, 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
listed, or, if the notes are not so listed, on a pro rata basis, by lot or in
a manner as it shall deem fair and appropriate. However, after the redemption
in part, all notes must be in amounts of $1,000 or integral multiples of
$1,000 or amounts of (Euro)1,000 or integral multiples of (Euro)1,000, as
applicable. Notices of redemption may not be conditional. If any note is to be
redeemed in part only, the notice of redemption that relates to the note must
state the portion of the principal amount of the note to be redeemed. A note
in principal amount equal to the unredeemed portion will be issued in the name
of the holder upon cancellation of the original note. Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on notes or portions of them called
for redemption and, unless we default in the payment of the redemption price,
notes or portions of them called for redemption will no longer be deemed
outstanding.

   To the extent that the euro notes may be listed on the Luxembourg Stock
Exchange and the rules of the Luxembourg Stock Exchange so require, we will,
once in each year in which there has been a partial redemption of any of the
euro notes, cause to be published in a leading daily newspaper of general
circulation in Luxembourg (which is expected to be the Luxembourger Wort) a
notice specifying the aggregate principal amount of euro notes outstanding and
a list of the euro notes drawn for redemption but not surrendered.

Sinking Fund

   The notes are not entitled to the benefit of any sinking fund.

Repurchase at the Option of Holders

 Change of Control

   If a Change of Control occurs at any time, then each holder of notes has the
right to require that we purchase the holder's notes at a purchase price in
cash, in an amount equal to 101% of the principal amount of the notes or
portion of the notes, plus accrued and unpaid interest and liquidated damages,
if any, to the date of purchase. The holders may require that we purchase their
notes in whole or in part in integral multiples of $1,000 or (Euro)1,000, as
the case may be. Any purchase would be made pursuant to the Offer to Purchase
and in accordance with the other procedures set forth in the indenture. Within
30 days following the Change of Control, we will mail an Offer to Purchase to
each holder describing the transaction or transactions that constitute the
Change of Control and offering to purchase notes on the date specified. We will
comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations to the extent these laws and regulations are
applicable in connection with the purchase of the notes under the Offer to
Purchase.

   In the event a Change of Control occurs at a time when we are prohibited
from purchasing the notes, due to provisions of other debt agreements or
otherwise, we could seek the consent of our lenders to the purchase of notes or
could attempt to refinance the borrowings that contain this prohibition. If we
do not obtain a consent or repay borrowings, we will remain prohibited from
purchasing notes. In this case, our failure to purchase tendered notes would
constitute an Event of Default under the indenture, which could, in turn,
constitute a default under the terms of other debt agreements. See "Risk
Factors--We may not be able to effect repurchase of the notes upon a Change of
Control in accordance with the terms of the indenture."

   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 does not
contain provisions that permit the holders of the notes to require that we
repurchase or redeem the notes in the event of a takeover, recapitalization or
similar transaction.

   We will not be required to make an Offer to Purchase upon a Change of
Control if a third party:

  .  makes the Offer to Purchase in the manner, at the times and otherwise in
     compliance with the requirements set forth in the indenture applicable
     to the Offer to Purchase; and

  .  purchases all notes validly tendered and not withdrawn under the Offer
     to Purchase.

   The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of our assets and the assets of our subsidiaries taken as a whole. There is no
precise established definition of the phrase "substantially all" under
applicable law. Accordingly, the ability of a holder of notes to require us to
repurchase the notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of our assets and the assets of our
subsidiaries taken as a whole to another person or group may be uncertain.

Covenants

   The indenture contains the following covenants:

 Limitation on Debt

   We will not, and will not permit any of our Restricted Subsidiaries to,
Incur any Debt, other than the notes and Debt existing on the original issuance
date of the notes; provided that we may Incur Debt if, after giving effect to
the Incurrence of Debt and the receipt and application of the proceeds, the
Consolidated Debt to EBITDA Ratio would be greater than zero and less than 6:1.

   However, the following Debt may be Incurred, each item to be given
independent effect:

  (1) Permitted Senior Bank Debt;

                                       66
<PAGE>

  (2) Debt owed:

    .  to us evidenced by a promissory note; or

    .  to any Restricted Subsidiary; provided that any event which results
       in any Restricted Subsidiary ceasing to be a Restricted Subsidiary
       or any subsequent transfer of Debt, other than to us or another
       Restricted Subsidiary, is deemed, in each case, to constitute the
       Incurrence of Debt not permitted by this clause (2);

  (3) Debt or the Debt of any Restricted Subsidiary:

    .  in respect of performance, surety or appeal bonds or letters of
       credit in the ordinary course of business;

    .  arising under, or arising from, agreements providing for
       indemnification, adjustment of purchase price or similar
       obligations, or from Guarantees or letters of credit, surety bonds
       or performance bonds securing any of our obligations Incurred in
       connection with the disposition of any business, assets or
       Restricted Subsidiary other than Guarantees of Debt Incurred by any
       person acquiring all or any portion of the business, assets or
       Restricted Subsidiary for the purpose of financing an acquisition,
       in a principal amount not to exceed the gross proceeds actually
       received by us or any Restricted Subsidiary in connection with the
       disposition;

  (4) Debt which is exchanged for or the proceeds of which are used to
      refinance or refund, or any extension or renewal of (each a
      "refinancing"):

    .  the notes;

    .  Debt incurred pursuant to clauses (3), (5), (6), (7) and (9) of this
       paragraph and this clause (4), in each case in an aggregate
       principal amount not to exceed the principal amount of the Debt so
       refinanced, together with any accrued interest and any premium and
       other payment required to be made with respect to the Debt being
       refinanced or refunded, and any fees, costs, expenses, underwriting
       discounts or commissions and other payments paid or payable with
       respect to the Debt incurred pursuant to this clause (4); provided,
       however, that:

      .  Debt, the proceeds of which are used to refinance the notes, or
         Debt which is equal with or subordinate in right of payment to
         the notes, shall only be permitted if (x) in the case of any
         refinancing of the notes or Debt which is equal to the notes, the
         refinancing Debt is Incurred by us and made equal to the notes or
         subordinated to the notes, and (y) in the case of any refinancing
         of Debt which is subordinated to the notes, the refinancing Debt
         is Incurred by us and is subordinated to the notes in a manner
         that is at least as favorable to the holders as that of the Debt
         refinanced;

      .  the refinancing Debt by its terms, or by the terms of any
         agreement or instrument pursuant to which Debt is issued, does
         not have a final maturity prior to the final maturity of the Debt
         being refinanced and has an Average Life longer than the Average
         Life of the Debt being refinanced; and

      .  in the case of any refinancing of Debt Incurred by us, the
         refinancing of Debt may be Incurred only by us, and in the case
         of any refinancing of Debt Incurred by a Restricted Subsidiary,
         the refinancing of Debt may be Incurred only by the Restricted
         Subsidiary or by us;

  (5) Acquisition Debt or Acquisition Debt of any Restricted Subsidiary;

  (6) the new notes issued in the exchange offer and Additional Notes issued
      under the indenture;

  (7) Debt not to exceed, at any time outstanding, two times the Net Cash
      Proceeds received by us after the original issue date of the notes from
      the issuance and sale of our Capital Stock, other than

                                       67
<PAGE>

     Disqualified Stock, to a person that is not our Subsidiary, to the
     extent that Net Cash Proceeds have not been used pursuant to the third
     clause of clause (4) of the first paragraph or clauses (3), (4) or (6)
     of the second paragraph of the "Limitation on Restricted Payments"
     covenant described below to make a Restricted Payment; provided that the
     Debt does not have a final maturity prior to the final maturity of the
     notes and has an Average Life longer than the Average Life of the notes;

  (8) Existing Debt;

  (9) Debt or the Debt of any Restricted Subsidiary Incurred to finance the
      purchase or other acquisition of any property, inventory, asset or
      business directly or indirectly, by us or any Restricted Subsidiary
      used in, or to be used in, the System and Network Management Business;

  (10) Subordinated Debt not to exceed $300.0 million in principal
       outstanding at any time; provided that the calculation of the
       principal amount of Subordinated Debt excludes the principal amount of
       our 4 3/4% Convertible Subordinated Notes; and

  (11) our other Debt or other Debt of any Restricted Subsidiary not to
       exceed $50.0 million at any one time outstanding.

   For purposes of determining compliance with this covenant, in the event
that an item of Debt meets the criteria of more than one of the types of Debt
described in the above clauses, or is permitted in part under the first
paragraph of this covenant and in part under one or more of the above clauses,
we, in our sole discretion, shall classify, and from time to time may
reclassify, the item of Debt.

   For purposes of determining any particular amount of Debt under this
covenant, Guarantees, Liens or obligations with respect to letters of credit
supporting Debt otherwise included in the determination of the particular
amount will not be included.

 Limitation on Our Guarantees of Our Debt by Restricted Subsidiaries

   We may not permit any Restricted Subsidiary, directly or indirectly, to
Guarantee, assume or in any other manner become liable for the payment of any
of our Debt, other than our Debt:

  .  Incurred pursuant to clauses (1), (3), (5), (9) or (11) of the second
     paragraph of "Limitation on Debt;" or

  .  refinanced pursuant to clause (4) of the second paragraph of "Limitation
     on Debt" of Debt originally incurred under clause (3), (5) or (9) of the
     second paragraph of "Limitation on Debt," that is equal with or
     subordinate in right of payment to the notes unless:

    .  the Restricted Subsidiary simultaneously executes and delivers a
       supplemental indenture providing for a Guarantee of payment of the
       notes by the Restricted Subsidiary and, with respect to any Guarantee
       of our Debt that is subordinate in right of payment to the notes, the
       Guarantee shall be subordinated to the Restricted Subsidiary's
       Guarantee with respect to the notes at least to the same extent as
       the Debt is subordinated to the notes; and

    .  the Restricted Subsidiary waives, and will not in any manner
       whatsoever claim or take the benefit or advantage of, any rights of
       reimbursement, indemnity or subrogation or any other rights against
       us or any other Restricted Subsidiary as a result of any payment by a
       Restricted Subsidiary under its Guarantee until the notes have been
       paid in full.

   However, any Guarantee by a Restricted Subsidiary may provide by its terms
that it shall be automatically and unconditionally released and discharged
upon:

  .  any sale, exchange or transfer, to any person who is not one of our
     Affiliates, of all of our Capital Stock and the Capital Stock of each
     Restricted Subsidiary in, or all or substantially all of the assets of,
     the Restricted Subsidiary, which sale, exchange or transfer is not
     prohibited by the indenture; or

                                      68
<PAGE>

  .  the release or discharge of the Guarantee which resulted in the creation
     of the Restricted Subsidiary's Guarantee with respect to the notes,
     except a discharge or release by or as a result of payment under a
     Guarantee.

 Limitation on Restricted Payments

   We will not, and will not permit any Restricted Subsidiary directly or
indirectly to:

  (1) declare or pay any dividend or make any distribution on or with respect
      to its Capital Stock to persons other than us or any of our Restricted
      Subsidiaries, other than:

    .  dividends or distributions payable solely in shares of its Capital
       Stock, other than Disqualified Stock, or in options, warrants or
       other rights to acquire shares of Capital Stock;

    .  pro rata dividends or distributions on common stock of Restricted
       Subsidiaries held by minority stockholders; or

    .  dividends in respect of Disqualified Stock;

  (2) purchase, redeem, retire or otherwise acquire for value any shares of
      our Capital Stock or the Capital Stock of an Unrestricted Subsidiary
      including options, warrants or other rights to acquire shares of
      Capital Stock, held by any person, or any shares of Capital Stock of a
      Restricted Subsidiary, including options, warrants or other rights to
      acquire shares of Capital Stock, held by any person other than us or
      one of our Wholly Owned Restricted Subsidiaries;

  (3) make any voluntary or optional principal payment, or voluntary or
      optional redemption, repurchase, defeasance, or other acquisition or
      retirement for value, of our Debt that is subordinated in right of
      payment to the notes; or

  (4) make any Investment, other than a Permitted Investment, in any person
      (the payments or any other actions described in clauses (1) through (4)
      above being collectively "Restricted Payments") if, at the time of, and
      after giving effect to, the proposed Restricted Payment:

    .  a Default or Event of Default shall have occurred and be continuing;

    .  we could not Incur at least $1.00 of Debt under the first paragraph
       of the "Limitation on Debt" covenant; or

    .  the aggregate amount of all Restricted Payments, the amount, if
       other than in cash, to be determined in good faith by the board of
       directors, whose determination shall be conclusive and evidenced by
       a board resolution, made after the date of original issuance of the
       notes shall exceed the sum of:

      .  cumulative Consolidated EBITDA since the date of original
         issuance of the notes through the last day of the last full
         fiscal quarter ending immediately preceding the date of the
         Restricted Payment for which quarterly or annual financial
         statements are available; minus

      .  1.5 times our cumulative Consolidated Interest Expense since the
         date of original issuance of the notes through the last day of
         the last full fiscal quarter ending immediately preceding the
         date of the Restricted Payment for which quarterly or annual
         financial statements are available, plus

      .  the aggregate Net Cash Proceeds received by us after the original
         issuance date of the notes from the issuance and sale permitted
         by the indenture of our Capital Stock, other than Disqualified
         Stock, to a person who is not one of our Subsidiaries, including
         an issuance or sale permitted by the indenture of our Debt for
         cash subsequent to the original issuance date of the notes upon
         the conversion of Debt into our Capital Stock, other than
         Disqualified Stock, or from the issuance to a person who is not
         one of our Subsidiaries of any options,

                                       69
<PAGE>

         warrants or other rights to acquire our Capital Stock, in each
         case, exclusive of any Disqualified Stock or any options,
         warrants or other rights that are redeemable at the option of the
         holder, or are required to be redeemed, prior to the stated final
         maturity date of the notes, in each case except to the extent Net
         Cash Proceeds are used to Incur Debt pursuant to clause (7) of
         the second paragraph under the "Limitation on Debt" covenant,
         plus

      .   amount equal to the net reduction in Investments, other than

referred to in clauses (3), (4) and (6), shall be included in calculating
whether the conditions of the third clause of clause (4) of the first
paragraph of this "Limitation on Restricted Payments" covenant have been met
with respect to any subsequent Restricted Payments. In the event the proceeds
of an issuance of our Capital Stock are used for the redemption, repurchase or
other acquisition of the notes, or Debt that is equal with the notes, then the
Net Cash Proceeds of the issuance shall be included in the third clause of
clause (4) of the first paragraph of this "Limitation on Restricted Payments"
covenant only to the extent the proceeds are not used for redemption,
repurchase or other acquisition of Debt.

 Limitation on Asset Sales

   We will not, and will not permit any Restricted Subsidiary to, consummate
an Asset Sale unless:

  .  we or the Restricted Subsidiary, as the case may be, receive
     consideration at the time of the Asset Sale at least equal to the fair
     market value of the assets sold or otherwise disposed of, as evidenced
     by a resolution of the board of directors; and

  .  at least 75% of the consideration received by us or the Restricted
     Subsidiary, as the case may be, from the Asset Sale shall be cash or
     other Qualified Consideration.

   We or any Restricted Subsidiary may, within 365 days of the Asset Sale,
invest the Net Cash Proceeds:

  .  in property or assets used, or to be used, in the System and Network
     Management Business, or in a company engaged primarily in the System and
     Network Management Business, if and to the extent otherwise permitted
     under the indenture; or

  .  to repay our Secured Debt or the Secured Debt of any Restricted
     Subsidiary.

   The amount of the Net Cash Proceeds not used or invested within 365 days of
the Asset Sale in the manner described in the foregoing clauses shall
constitute "Excess Proceeds."

                                      71
<PAGE>

   In the event that Excess Proceeds exceed $10.0 million, we shall make an
Offer to Purchase that amount of notes equal to the amount of Excess Proceeds
at a price equal to 100% of the principal amount of the notes to be purchased,
plus accrued and unpaid interest and liquidated damages, if any, to the date of
purchase and, to the extent required by the terms of the notes, our other Debt
that is equal with the notes or Debt of a Restricted Subsidiary. Each Offer to
Purchase shall be mailed within 30 days following the date that we shall become
obligated to purchase notes with any Excess Proceeds. Following the completion
of an Offer to Purchase, the amount of Excess Proceeds shall be deemed to be
reset at zero and, to the extent there are any remaining Excess Proceeds we may
use Excess Proceeds for any use which is not otherwise prohibited by the
indenture.

   We will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations to the extent the laws and
regulations are applicable in connection with the purchase of notes pursuant to
the Offer to Purchase.

   Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries

   We may not, and may not permit any Restricted Subsidiary 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:

  .  pay dividends, in cash or otherwise, or make any other distributions in
     respect of its Capital Stock owned by us or any other Restricted
     Subsidiary or pay any Debt or other obligation owed to us or any other
     Restricted Subsidiary;

  .  make loans or advances to us or any other Restricted Subsidiary; or

  .  transfer any of its property or assets to us or any other Restricted
     Subsidiary.

   However, we may, and may permit any Restricted Subsidiary to, suffer to
exist any the encumbrance or restriction:

  .  pursuant to any agreement in effect on the date of original issuance of
     the notes, and any amendments, extensions, refinancings, renewals or
     replacements of agreements, provided that the amendments, encumbrances
     and restrictions in any extensions, refinancings, renewals or
     replacements are no less favorable in any material respect to the
     holders, than those encumbrances or restrictions that are then in effect
     and that are being extended, refinanced, renewed or replaced;

  .  existing under or by reason of applicable law;

  .  existing in connection with any Permitted Senior Bank Debt or any Debt
     incurred pursuant to clause (5) of the second paragraph of "Limitations
     on Debt;"

  .  pursuant to an agreement existing prior to the date on which the person
     became a Restricted Subsidiary and not Incurred in anticipation of
     becoming a Restricted Subsidiary, which encumbrance or restriction is
     not applicable to any person, or the properties or assets of any person,
     other than the person so acquired;

  .  pursuant to an agreement entered into in connection with Debt Incurred
     under clause (4) of the second paragraph of the "Limitation on Debt"
     covenant; provided, however, that the provisions contained in any
     agreement related to an encumbrance or restriction are no more
     restrictive in any material respect than the provisions contained in the
     agreement the subject of the refinancing clause (4) of the second
     paragraph of the "Limitation on Debt" covenant;

  .  restrictions contained in any agreement relating to a Lien of a
     Restricted Subsidiary or us otherwise permitted under the indenture, but
     only to the extent the restrictions restrict the transfer of the
     property subject to the Lien;

                                       72
<PAGE>

  .  customary nonassignment provisions entered into in the ordinary course
     of business in leases, licenses and other contracts to the extent the
     provisions restrict the transfer, sublicensing or any license or
     subletting of any lease or the assignment of rights under any such
     contract;

  .  any restriction with respect to a Restricted Subsidiary imposed pursuant
     to an agreement which has been entered into for the sale or disposition
     of all or substantially all of the Capital Stock or assets of the
     Restricted Subsidiary; provided that consummation of the transaction
     would not result in an Event of Default or an event that, with the
     passing of time or the giving of notice or both, would constitute an
     Event of Default, that the restriction terminates if the transaction is
     closed or abandoned and that the closing or abandonment of the
     transaction occurs within one year of the date the agreement was entered
     into;

  .  any restriction imposed pursuant to contracts for the sale of assets
     with respect to the transfer of the assets to be sold pursuant to the
     contract;

  .  arising or agreed to in the ordinary course of business, not relating to
     any Debt, and that do not, individually, or in the aggregate, detract
     from the value of our property or assets or the property or assets of
     any Restricted Subsidiary in any manner material to us or any Restricted
     Subsidiary; or

  .  the encumbrance or restriction is contained in the terms of any
     agreement pursuant to which the Debt was issued if:

    .  the encumbrance or restriction applies only in the event of a
       payment default or a default with respect to a financial covenant
       contained in the Debt or agreement,

    .  the encumbrance or restriction is not materially more
       disadvantageous to the holders of the notes than is customary in
       comparable financings, and

    .  we determine that any encumbrance or restriction will not materially
       affect our ability to make principal or interest payments on the
       notes.

 Limitation on Liens

   We may not, and may not permit any Restricted Subsidiary to, Incur or suffer
to exist any Lien, on or with respect to any property or assets now owned or
hereafter acquired to secure any Debt without making, or causing the Restricted
Subsidiary to make, effective provision for securing the notes:

  .  equally and ratably with Debt as to such property or assets for so long
     as the Debt will be so secured or;

  .  in the event the Debt is our Debt which is subordinate in right of
     payment to the notes, prior to this Debt as to such property or assets
     for so long as this Debt will be so secured.

   The foregoing restrictions shall not apply to:

  .  Liens in existence on the date of original issuance of the notes;

     does not extend to any property other than the property securing the

     the "Limitation on Debt" covenant.

 Limitation on Issuance or Sale of Capital Stock of Restricted Subsidiaries

   We will not sell, and will not permit any Restricted Subsidiary, directly or

Subsidiary, including options, warrants or other rights to purchase shares of
Capital Stock, except:

  .  issuances of director's qualifying shares or sales to foreign nationals
     of shares of Capital Stock of foreign Restricted Subsidiaries, to the
     extent required by applicable law;

  .  if, immediately after giving effect to an issuance or sale, the
     Restricted Subsidiary would no longer constitute a Restricted Subsidiary
     and any Investment in any person remaining after giving effect to the
     issuance or sale would have been permitted to be made under the
     "Limitation on Restricted Payments" covenant if made on the date of the
     issuance or sale; or

  .  issuances or sales of common stock of a Restricted Subsidiary.

 Transactions with Affiliates and Related Persons

   We may not, and may not permit any Restricted Subsidiary to, enter into any
transaction, or series of related transactions, not in the ordinary course of
business with our Affiliates or Related Persons, other than us or a Wholly
Owned Restricted Subsidiary, involving aggregate consideration in excess of
$5.0 million, including any Investment, either directly or indirectly, unless
the transaction is on terms no less favorable to us or the Restricted
Subsidiary than those that could be obtained in a comparable arm's-length
transaction with an entity that is not an Affiliate or Related Person and is in
our best interests or the best interests of the Restricted Subsidiary. For any
transaction, or series of related transactions, that involves less than or
equal to $10.0 million, our Chief Executive Officer, President or Chief
Operating Officer shall determine that the transaction satisfies the above
criteria and shall evidence a determination by an Officer's Certificate filed
with the trustee. For any transaction that involves in excess of $10.0 million:

  .  a majority of the disinterested members of the board of directors shall
     determine that the transaction satisfies the above criteria; or

  .  we shall obtain a written opinion of a nationally recognized investment
     banking or appraisal firm stating that the transaction is fair to us or
     the Restricted Subsidiary.

   The limitation above does not apply, and shall not apply, to:

     or any Restricted Subsidiary to us or any Restricted Subsidiary;

     any Restricted Subsidiary's officers, directors or employees, including

     of business.

 Limitation on Sale-Leaseback Transactions

   We will not, and will not permit any Restricted Subsidiary to, enter into
any sale-leaseback transaction involving any of our assets or properties,
whether now owned or hereafter acquired, whereby we or a Restricted Subsidiary
sell or transfer the assets or properties and then or thereafter lease the
assets or properties or any part thereof or any other assets or properties that
we or the Restricted Subsidiary, as the case may be, intend to use for
substantially the same purpose or purposes as the assets or properties sold or
transferred.

   The above restriction does not apply to any sale-leaseback transaction if:

  .  the lease is for a period, including renewal rights, of not in excess of
     three years;

  .  the sale-leaseback transaction is consummated within 180 days after the
     purchase of the assets subject to the transaction;

  .  the transaction is solely between us and any Wholly Owned Restricted

  .  we or the Restricted Subsidiary, within 12 months after the sale or
     transfer of any assets or properties is completed, apply an amount no
     less than the Net Cash Proceeds received from the sale in accordance
     with second paragraph of "--Limitation on Asset Sales."

 Provision of Financial Information

   Whether or not we are required to be subject to Section 13(a) or 15(d) of
the Exchange Act, we shall file with the Commission the annual reports,
quarterly reports and other documents which we would have been required to file
with the Commission pursuant to Section 13(a) or 15(d) or any successor
provision if we were so required. These documents must be filed with the
Commission on or prior to the respective dates (each a "Required Filing Date,"
collectively, the "Required Filing Dates") by which we would have been required
so to file the documents if we were so required. We shall also in any event:

  .  within 15 days of each Required Filing Date (1) transmit by mail to all
     holders, as their names and addresses appear in the Note Register,
     without cost to the holders, and (2) file with the trustee, copies of
     the annual reports, quarterly reports and other documents which we file
     with the Commission pursuant to Section 13(a) or 15(d) or any successor
     provision or would have been required to file with the Commission
     pursuant to Section 13(a) or 15(d) or any successor provisions if we
     were required to be subject to these Sections; and

  .  if filing these documents by us with the Commission is not permitted
     under the Exchange Act, promptly upon written request supply copies of
     these documents to any prospective holder.

 Unrestricted Subsidiaries

   We may designate any of our Subsidiaries to be an "Unrestricted Subsidiary"
as provided below in which event the Subsidiary and each other person that is
then, or thereafter becomes, a Subsidiary of the Subsidiary will be deemed to
be an Unrestricted Subsidiary. "Unrestricted Subsidiary" means:

  .  any Subsidiary designated as such by the Board of Directors as set forth
     below where (1) no default with respect to any Debt of the Subsidiary or
     any Subsidiary of the Subsidiary, including any right

                                       75
<PAGE>

     which the holders thereof may have to take enforcement action against
     the Subsidiary, would permit, upon notice, lapse of time or both, any
     holder of any other Debt in a principal amount in excess of $10.0
     million of us and our Subsidiaries, other than another Unrestricted
     Subsidiary, to declare a default on the other Debt or cause the payment
     thereof to be accelerated or payable prior to its final scheduled
     maturity and (2) we could make a Restricted Payment in an amount equal
     to the greater of the fair market value and book value of the Subsidiary
     pursuant to "Limitation on Restricted Payments" and the amount is
     thereafter treated as a Restricted Payment for the purpose of
     calculating the aggregate amount available for Restricted Payments
     thereunder; and

  .  any Subsidiary of an Unrestricted Subsidiary.

   The board of directors may not designate a Subsidiary to be an Unrestricted
Subsidiary if the Subsidiary owns any Capital Stock of, or owns or holds any
Lien on any property of, any of our other Subsidiaries which is not a
Subsidiary of the Subsidiary to be so designated or otherwise an Unrestricted
Subsidiary. The board of directors may designate any Unrestricted Subsidiary a
Restricted Subsidiary and shall be deemed to have made this designation if at
that time the condition set forth in the item listed under in the definition
of "Unrestricted Subsidiary" shall cease to be true.

Mergers, Consolidations and Certain Sales of Assets

   We may not, in a single transaction or a series of related transactions,
(1) consolidate or merge with or into any other person or permit any other
person to consolidate or merge with or into us or (2) directly or indirectly
transfer, sell, lease or otherwise dispose of all or substantially all of its
assets, unless:

  .  in a transaction in which we do not survive or in which we sell, lease
     or otherwise dispose of all or substantially all of our assets, the
     successor entity to us shall be organized and validly existing under the
     laws of the United States of America, any State thereof or the District
     of Columbia, and shall expressly assume, by a supplemental indenture
     executed and delivered to the trustee in form satisfactory to the
     trustee, all of our obligations under the indenture;

  .  immediately before and after giving effect to the transaction and
     treating any Debt which becomes our obligation or an obligation of a
     Restricted Subsidiary as a result of the transaction as having been
     Incurred by us or the Restricted Subsidiary at the time of the
     transaction, no Event of Default or event that with the passing of time
     or the giving of notice, or both, would constitute an Event of Default
     shall have occurred and be continuing;

  .  except in the case of any such consolidation or merger of us with or
     into, or any such transfer, sale, lease or other disposition of assets
     to, a Wholly Owned Restricted Subsidiary, immediately after giving
     effect to the transaction, our Consolidated Net Worth, or the
     Consolidated Net Worth of any other successor entity to us, is equal to
     or greater than our immediately prior to the transaction; and

  .  except in the case of any consolidation or merger of us with or into, or
     any such transfer, sale, lease or other disposition of assets to, a
     Wholly Owned Restricted Subsidiary, immediately after giving effect to
     the transaction and treating any Debt which becomes our obligation or
     the obligation of a Restricted Subsidiary as a result of the transaction
     as having been Incurred by us or the Restricted Subsidiary at the time
     of the transaction, we, including any successor entity to us, could
     Incur at least $1.00 of additional Debt pursuant to the provisions of
     the indenture described in the first paragraph under "Limitation on
     Debt" above.

Events of Default

   The following will be "Events of Default" under the indenture:

  .  failure to pay principal of or premium, if any, on any note when due
     upon acceleration, optional or mandatory redemption, required repurchase
     or otherwise;

  .  failure to pay interest on any note when due, and such default continues

     aggregate principal amount of outstanding notes;

  .  (1) any default by us or any Material Restricted Subsidiary in the
     payment of the principal, premium, if any, or interest has occurred with
     respect to amounts in excess of $10.0 million under any agreement,
     indenture or instrument evidencing Debt when the same shall become due
     and payable in full and the default shall have continued after any
     applicable grace period and shall not have been cured or waived and, if
     not already matured at its final maturity in accordance with its terms,
     the holders of the Debt shall have the right to accelerate the Debt, or
     (2) any event of default as defined in any of our agreements, indentures
     or instruments or any agreements, indentures or instruments of any
     Restricted Subsidiary evidencing Debt in excess of $10.0 million shall
     have occurred and the Debt thereunder, if not already matured at its
     final maturity in accordance with its terms, shall have been
     accelerated;

  .  the rendering of a final judgment or judgments against us or any
     Material Restricted Subsidiary in an amount in excess of $10.0 million
     which remains undischarged or unstayed for a period of 60 days after the
     date on which the right to appeal has expired; and

  .  events of bankruptcy, insolvency or reorganization affecting us or any
     Material Restricted Subsidiary.

   Subject to the provisions of the indenture relating to the duties of the
trustee in case an Event of Default shall occur and be continuing, the trustee
will be under no obligation to exercise any of its rights or powers under the
indenture at the request or direction of any of the holders, unless the holders
shall have offered to the

                                       88
<PAGE>

trustee reasonable indemnity. Subject to provisions for the indemnification of
the trustee, the holders of a majority in aggregate principal amount of the
outstanding notes will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the trustee or exercising
any trust or power conferred on the trustee.

   If an Event of Default, other than events of bankruptcy, insolvency or
reorganization affecting us or any Material Restricted Subsidiary, shall occur
and be continuing, either the trustee or the holders of at least 25% in
aggregate principal amount of the outstanding notes may accelerate the maturity
of all notes; provided, however, that after the acceleration, but before a
judgment or decree based on acceleration, the holders of a majority in
aggregate principal amount of outstanding notes may, under various
circumstances, rescind and annul the acceleration if all Events of Default,
other than the nonpayment of accelerated principal, have been cured or waived
as provided in the indenture. If an event of bankruptcy, insolvency or
reorganization affecting us or any Material Restricted Subsidiary occurs, the
principal of and any accrued interest on the notes then outstanding will ipso
facto become immediately due and payable without any declaration or other act
on the part of the trustee or any holder. For information as to waiver of
defaults, see "Modification and Waiver."

   No holder of any note will have any right to institute any proceeding with
respect to the indenture or for any remedy thereunder, unless the holder shall
have previously given to the trustee written notice of a continuing Event of
Default and unless also the holders of at least 25% in aggregate principal
amount of the outstanding notes shall have made written request, and offered
reasonable indemnity, to the trustee to institute such proceeding as trustee,
and the trustee shall not have received from the holders of a majority in
aggregate principal amount of the outstanding notes a direction inconsistent
with the request and shall have failed to institute a proceeding within 60
days. However, these limitations do not apply to a suit instituted by a holder
of a note for enforcement of payment of the principal of and premium, if any,
or interest on such note on or after the respective due dates expressed in the
note.

   We are required to furnish to the trustee annually a statement as to the
performance by us of our obligations under the indenture and as to any default
in such performance.

Satisfaction and Discharge of the Indenture

   The indenture will cease to be of further effect as to all outstanding
notes, except as to:

  .  rights of registration of transfer and exchange and our right of
     optional redemption;

  .  substitution of apparently mutilated, defaced, destroyed, lost or stolen
     notes;

  .  rights of holders to receive payment of principal and interest on the
     notes;

  .  rights, obligations and immunities of the trustee under the indenture;
     and

  .  rights of the holders of the notes as beneficiaries of the indenture
     with respect to any property deposited with the trustee payable to all
     or any of them if:

    .  we will have paid or caused to be paid the principal of and interest
       on the notes as and when they will have become due and payable; or

    .  all outstanding notes, except lost, stolen or destroyed notes which
       have been replaced or paid, have been delivered to the trustee for
       cancellation.

Defeasance

   At our option, if applicable:

  (1) we will be discharged from any and all obligations in respect of the
      outstanding notes; or

  (2) we may omit to comply with various restrictive covenants, and this
      omission shall not be deemed to be an Event of Default under the
      indenture and the notes,

                                       89
<PAGE>

in either case (1) or (2) upon irrevocable deposit with the trustee, in trust,
of money and/or U.S. government obligations which will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of
independent certified public accountants, to pay the principal of and premium,
if any, and each installment of interest if any, on the outstanding notes.

   With respect to clause (2), the obligations under the indenture other than
with respect to these covenants and the Events of Default other than the Events
of Default relating to these covenants above shall remain in full force and
effect. A trust may only be established if, among other things:

  .  with respect to clause (1), we have received from, or there has been
     published by, the Internal Revenue Service a ruling or there has been a
     change in law, which in the opinion of counsel provides that holders of
     the notes will not recognize gain or loss for U.S. federal income tax
     purposes as a result of the deposit, defeasance and discharge and will
     be subject to U.S. federal income tax on the same amount, in the same
     manner and at the same times as would have been the case if the deposit,
     defeasance and discharge had not occurred; or, with respect to clause
     (2), we have delivered to the trustee an opinion of counsel to the
     effect that the holders of the notes will not recognize gain or loss for
     U.S. federal income tax purposes as a result of the deposit and
     defeasance and will be subject to U.S. federal income tax on the same
     amount, in the same manner and at the same times as would have been the
     case if the deposit and defeasance had not occurred;

  .  the deposit, defeasance and discharge will not result in a breach or
     violation of, or constitute a default under, any agreement or instrument
     to which we or any Restricted Subsidiary are a party or by which we and
     any Restricted Subsidiary are bound;

  .  no Event of Default or event that with the passing of time or the giving
     of notice, or both, shall constitute an Event of Default, shall have
     occurred and be continuing;

  .  we have delivered to the trustee an opinion of counsel to the effect
     that the deposit shall not cause the trustee or the trust so created to
     be subject to the Investment Company Act of 1940; and

  .  other customary conditions precedent are satisfied.

Modification and Waiver

   Modifications and amendments of the indenture may be made by us and the
trustee with the consent of the holders of a majority in aggregate principal
amount of the outstanding notes; provided, however, that no modification or
amendment may, without the consent of the holder of each outstanding note
affected thereby:

  .  change the stated maturity of the principal of, or any installment of
     interest on, any note;

  .  reduce the principal amount of, or premium or interest on, any note;

  .  change the place or currency of payment of principal of, or premium or
     interest on, any note;

  .  impair the right to institute suit for the enforcement of any payment on
     or with respect to any note;

  .  reduce the above-stated percentage of outstanding notes necessary to
     modify or amend the indenture;

  .  reduce the percentage of aggregate principal amount of outstanding notes
     necessary for waiver of compliance with provisions of the indenture or
     for waiver of defaults;

  .  modify any provisions of the indenture relating to the modification and
     amendment of the indenture or the waiver of past defaults or covenants,
     except as otherwise specified; or

  .  following the mailing of any Offer to Purchase, modify any Offer to
     Purchase for the notes required under the "Limitation on Asset Sales"
     and the "Change of Control" covenants contained in the indenture in a
     manner materially adverse to the holders thereof.

                                       90
<PAGE>

   However, without the consent of any holder, we and the trustee may amend or
supplement the indenture or the notes to cure any ambiguity, defect or
inconsistency; provided that this action does not adversely affect the
interests of the holders of the notes in any material respect, to provide for
the assumption of our obligations to holders of notes in the case of a merger
or consolidation, to secure the notes, to add to our covenants for the benefits
of the holders or to comply with requirements of the Commission in order to
effect or maintain the qualification of the indenture under the Trust Indenture
Act.

   The holders of a majority in aggregate principal amount of the outstanding
notes, on behalf of all holders of notes, may waive compliance by us with
restrictive provisions of the indenture. Subject to rights of the trustee, as
provided in the indenture, the holders of a majority in aggregate principal
amount of the outstanding notes, on behalf of all holders of notes, may waive
any past default under the indenture, except a default in the payment of
principal, premium or interest or a default arising from failure to purchase
any note tendered pursuant to an Offer to Purchase.

Governing Law

   The indenture and the old notes are, and the new notes will be, governed by
the laws of the State of New York.

The Trustee

   The indenture provides that, except during the continuance of an Event of
Default, the trustee will perform only such duties as are specifically set
forth in the indenture. During the existence of an Event of Default, the
trustee will exercise such rights and powers vested in it under the indenture
and use the same degree of care and skill in its exercise as a prudent person
would exercise under the circumstances in the conduct of such persons own
affairs.

   The indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the trustee, should it
become our creditor, to obtain payment of claims in certain cases or to realize
on certain property received by it in respect of any such claim as security or
otherwise. The trustee is permitted to engage in other transactions with us or
any Affiliate; provided, however, that if it acquires any conflicting interest,
as defined in the indenture or in the Trust Indenture Act, it must eliminate
the conflict or resign.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   The following is a general discussion of material U.S. federal income
considerations relevant to holders of the notes including material U.S. federal
income tax consequences of the exchange of old notes for new notes pursuant to
the exchange offer. This discussion is based upon the Internal Revenue Code of
1986, as amended (the "Code"), Treasury Regulations, Internal Revenue Service
("IRS") rulings and judicial decisions now in effect, all of which are subject
to change, possibly with retroactive effect, or different interpretations.
There can be no assurance that the IRS will not challenge one or more of the
tax consequences described herein, and we have not obtained, nor does it intend
to obtain, a ruling from the IRS with respect to the U.S. federal income tax,
state tax, local tax, foreign tax or other tax consequences of acquiring or
holding notes. This discussion does not purport to deal with all aspects of
U.S. federal income taxation that may be relevant to a particular holder in
light of the holder's circumstances (for example, persons subject to the
alternative minimum tax provisions of the Code). Also, it is not intended to be
wholly applicable to all categories of investors, some of which, such as
dealers in securities, banks, insurance companies, tax-exempt (employment,
charitable or other) organizations, and persons holding notes as part of a
hedging or conversion transaction or straddle or persons deemed to sell notes
under the constructive sale provisions of the Code, may be subject to special
rules. The discussion also does not discuss any aspect of state, local or
foreign law, or U.S. federal estate and gift tax law. This discussion is
limited to purchasers of notes who hold the notes as "capital assets" within
the meaning of Section 1221 of the Code.

   All purchasers of the notes are advised to consult their own tax advisors
regarding the federal, state, local and foreign tax consequences of the
purchase, ownership and disposition of the notes.

U.S. Holders

   As used herein, the term "U.S. Holder" means the beneficial owner of a note
that for United States federal income tax purposes is:

  .  a citizen or resident (as defined in Section 7701 (b) of the Code) of
     the United States;

  .  a corporation, partnership or other entity formed under the laws of the
     United States or any political subdivision thereof;

  .  an estate the income of which is subject to U.S. federal income taxation
     regardless of its source; or

  .  a trust which is subject to the supervision of a court within the United
     States and the control of a United States person as described in Section
     7701(a)(30) of the Code.

  .  A "Non-U.S. Holder" is any holder other than a U.S. Holder.

 Interest

   Stated interest on the notes will generally be includable in a U.S. Holder's
gross income and taxable as ordinary income for U.S. federal income tax
purposes at the time it is paid or accrued in accordance with the U.S. Holder's
regular method of accounting.

 Sale, Exchange or Redemption

   Each U.S. Holder generally will recognize capital gain or loss upon the
sale, exchange, redemption or other disposition of the notes measured by the
difference, if any, between:

  .  the amount of cash and the fair market value of any property received,
     except to the extent that such cash or other property is attributable to
     the payment of accrued interest not previously included in income, which
     amount will be taxable as ordinary income; and

  .  such holder's adjusted tax basis in the notes;


                                       92
<PAGE>

Capital gain recognized by an individual U.S. Holder generally will be subject
to a maximum United States Federal income tax rate of:

  .  39.6% if the U.S. Holder held the asset for not more than 12 months
     before the disposition; or

  .  20% if the U.S. Holder held the asset for more than 12 months before the
     disposition.

A holder's initial tax basis in a note will be the amount paid therefor.

   The exchange of the old notes for the new notes pursuant to the exchange
offer should not be treated as an "exchange" for federal income tax purposes
because the new notes should not differ materially in either kind or extent
from the old notes and because the exchange will occur by operation of the
terms of the old notes. A U.S. Holder's adjusted tax basis in the new notes
should be the same as such Holder's adjusted tax basis in the old notes. A U.S.
Holder's holding period for the new notes received pursuant to the exchange
offer should include its holding period for the old notes surrendered therefor.

 Information Reporting and Backup Withholding

   A U.S. Holder of notes may be subject to "backup withholding" at a rate of
31% with respect to "reportable payments," including interest payments, and,
under various circumstances, principal payments on the notes and proceeds from
the sale, exchange or redemption of the notes. These backup withholding rules
apply if the U.S. Holder, among other things:

  .  fails to furnish a social security number or other taxpayer
     identification number ("TIN") certified under penalties of perjury
     within a reasonable time after the request therefor;

  .  furnishes a TIN as to which the IRS provides notification that it is an
     incorrect TIN;

  .  fails to report properly interest; or

  .  under various circumstances, fails to provide a certified statement,
     signed under penalties of perjury, that the TIN furnished is correct and
     that such U.S. Holder is not subject to backup withholding.

   A U.S. Holder who does not provide us with its correct TIN also may be
subject to penalties imposed by the IRS. Any amount withheld from a payment to
a U.S. Holder under the backup withholding rules is creditable against the U.S.
Holder's federal income tax liability, provided that the required information
is furnished to the IRS. Backup withholding will not apply, however, with
respect to payments made to certain holders, including corporations and tax-
exempt organizations, provided their exemptions from backup withholding are
properly established.

   We will report to the U.S. Holders of notes and to the IRS the amount of any
"reportable payments" for each calendar year and the amount of tax withheld, if
any, with respect to such payments.

US Holder of Euro Denominated Notes

   In addition to the information described above regarding U.S. Holders, the
following applies to U.S. Holders of a Euro denominated note ("Euro Note").

 Interest

   The stated interest on the notes generally will be taxable to a U.S. Holder
as ordinary income at the time that it is paid or accrued, in accordance with
the Holder's method of accounting for federal income tax purposes.

   Interest paid on a Euro Note will be includible in income by a U.S. Holder
in an amount equal to the U.S. Dollar value of the payment, regardless of
whether the payment is in fact converted to U.S. Dollars at that time.

                                       93
<PAGE>

If such U.S. Holder uses the cash method of accounting for tax purposes, the
U.S. Dollar value of such payment is determined using the spot rate at the time
such payment is received. If a U.S. Holder uses the accrual method of
accounting for tax purposes, the U.S. Dollar value of such payment is
determined using the average exchange rate during the relevant accrual period
(or partial accrual period with respect to interest paid in a subsequent
taxable year) or, if elected, the spot rate (a) on the last day of the relevant
accrual period (or partial accrual period) or (b) on the payment date, if such
date is within five business days of the last day of the accrual period or
taxable year. Any differences in the exchange rate between the rate at which
interest on a Euro Note is included in income and the spot rate on the payment
(or disposition) date for interest will result in exchange gain or loss with
respect to the related amount of interest, and will generally be treated as
ordinary income or loss for U.S. federal income tax purposes. The U.S. Dollar
value of interest accrued or received, adjusted for any exchange gain or loss
with respect to the amount accrued, generally will be a U.S. Holder's tax basis
in the Euros received as interest on a Euro Note.

 Sale, Exchange and Redemption of a Euro Note

   The cost of a Euro Note to a U.S. Holder will be the U.S. Dollar value of
the Euro purchase price translated at the spot rate for the date of purchase
(or, in some cases, the settlement date). The conversion of U.S. Dollars into
Euros and the immediate use of those Euros to purchase a Euro Note generally
will not result in a taxable gain or loss for a U.S. Holder. A U.S. Holder will
have a tax basis in any Euro received on the sale, exchange or retirement of a
Euro Note equal to the U.S. Dollar value of the Euro on the date of receipt or
the Euro note is disposed of (or deemed disposed of).

   Upon the sale, exchange, retirement or repayment of a Euro Note, a U.S.
Holder will also recognize exchange gain or loss to the extent that the rate of
exchange on the date of retirement or disposition differs from the rate of
exchange on the date the Euro Note was acquired, or deemed acquired. Exchange
gain or loss is recognized, however, only to the extent of total gain or loss
on the transaction. For purposes of determining the total gain or loss on the
transaction, a U.S. Holder's tax basis in a Euro Note will generally equal the
U.S. Dollar cost of the Euro Note. Exchange gain or loss recognized by a U.S.
Holder will generally be treated as ordinary income or loss.

   Any gain recognized by a U.S. Holder on the sale, exchange or redemption of
a Euro Note generally will be treated as U.S. source income for U.S. foreign
tax credit purposes. Generally a loss recognized upon such a sale, exchange,
redemption or other disposition of a Euro Note will be allocated to U.S. source
income.

Non-U.S. Holders

   The following discussion is limited to the U.S. federal income tax
consequences relevant to a Non-U.S. Holder. Non-U.S. Holders should consult
their own tax advisors concerning the state, local, foreign and other tax
consequences of the purchase, ownership and disposition of the notes.

   For purposes of U.S. federal income tax on interest discussed below, a Non-
U.S. Holder (as defined above) includes a non-resident fiduciary of an estate
or trust. For purposes of the following discussion, interest and gain on the
sale, exchange or other disposition of a note will be considered to be "U.S.
trade or business income" if such income or gain is:

  .  effectively connected with the conduct of a trade or business within the
     U.S. of such Non-U.S. Holder; or

  .  in the case of certain residents of certain countries which have an
     income tax treaty in force with the U.S., attributable to a permanent
     establishment or, in the case of an individual, a fixed base, in the
     United States as such terms are defined in the applicable treaty.

                                       94

 Stated Interest

   Generally any interest paid to a Non-U.S. Holder of a note that is not U.S.
trade or business income will not be subject to U.S. federal income tax if the
interest qualifies as "portfolio interest." Generally interest on the notes
will qualify as portfolio interest if:

  .  the Non-U.S. Holder does not actually or constructively own 10% or more
     of the total combined voting power of all classes of our stock entitled
     to vote and is not a "controlled foreign corporation" with respect to
     which we are a "related person" within the meaning of the appropriate
     provisions of the Code;

  .  the Non-U.S. Holder, under penalty of perjury, certifies in general that
     the Non-U.S. Holder is not a U.S. person and such certificate provides
     the Non-U.S. Holder's name and address;

  .  the Non-U.S. Holder is not a bank receiving interest on an extension of
     credit made pursuant to a loan agreement made in the ordinary course of
     its trade or business; and

  .  the notes are in registered form.

   The gross amount of payments of interest to a Non-U.S. Holder that do not
qualify for the portfolio interest exemption and that are not U.S. trade or
business income will be subject to U.S. federal income tax at the rate of 30%,
unless a U.S. income tax treaty applies to reduce or eliminate such tax.
Interest payments that are considered as U.S. trade or business income will be
taxed at regular U.S. income tax rates rather than the 30% gross rate. In the
case of a Non-U.S. Holder that is a corporation, such U.S. trade or business
income may also be subject to the branch profits tax (which is generally
imposed on a foreign corporation on the actual or deemed repatriation from the
United States of earnings and profits attributable to U.S. trade or business
income) at a 30% rate unless a U.S. income tax treaty applies to reduce or
eliminate such tax. To claim the benefit of a tax treaty or to claim exemption
from withholding because the income is U.S. trade or business income, the Non-
U.S. Holder must provide a properly executed IRS Form 1001 or IRS Form 4224 (or
such successor forms as the IRS designates), as applicable, prior to the
payment of interest. Under recently issued U.S. Treasury Regulations that will
generally be effective on and after January 1, 2001 (the "Withholding
Regulations"), the required Forms 1001 and 4224 will be replaced by a new Form
W-8. Under the Withholding Regulations, a Non-U.S. Holder may under certain
circumstances be required to obtain a U.S. taxpayer identification number and
make certain certifications to us. Special procedures are provided in the
Withholding Regulations for payments through qualified intermediaries.
Investors should consult their tax advisors regarding the effect, if any, of
the Withholding Regulations.

 Sale, Exchange or Redemption of Notes

   Except as described below and subject to the discussion concerning backup
withholding, any gain realized by a Non-U.S. Holder on the sale, exchange or
redemption of a note generally will not be subject to U.S. federal income tax,
unless:

  .  such gain is U.S. trade or business income; or

  .  the Non-U.S. Holder is subject to tax pursuant to the provisions of U.S.
     tax law applicable to certain U.S. expatriates, including certain former
     citizens or residents of the United States.

   The exchange of the old notes for the new notes pursuant to the exchange
offer should not be treated as an "exchange" for federal income tax purposes
because the new notes should not differ materially in either kind or extent
from the old notes and because the exchange will occur by operation of the
terms of the old notes. A U.S. Holder's adjusted tax basis in the new notes
should be the same as such Holder's adjusted tax basis in the old notes. A U.S.
Holder's holding period for the new notes received pursuant to the exchange
offer should include its holding period for the old notes surrendered therefor.

                                       95

 Information Reporting and Backup Withholding

   We must report annually to the IRS and to each Non-U.S. Holder any interest
that is subject to withholding, or that is exempt from U.S. withholding tax
pursuant to a tax treaty, or interest that is exempt from U.S. tax under the
portfolio interest exception or because it is U.S. trade or business income.
Copies of these information returns may also be made available under the
provisions of a specific treaty or agreement to the tax authorities of the
country in which the Non-U.S. Holder resides. We may have to report to the IRS
payments of principal.

   Generally, information reporting and backup withholding of United States
federal income tax at a rate of 31% may apply to payments made by us or our
agents to Non-U.S. Holders if the payee fails to make the appropriate
certification that the holder is a non-U.S. person or if we or our paying agent
have actual knowledge that the payee is a United States person.

   The payment of the proceeds from the disposition of notes to or through a
United States office of a United States or foreign broker will be subject to
information reporting and backup withholding unless the owner provides
certification as to its Non-U.S. Holder status under penalty of perjury or
otherwise establishes an exemption, provided that the broker does not have
actual knowledge that the holder is a U.S. person or that the conditions of any
other exemption are not, in fact, satisfied. The proceeds of the disposition by
a Non-U.S. Holder of the notes to or through a foreign office of a broker will
generally not be subject to backup withholding. However, if such broker is a
U.S. person, a controlled foreign corporation for United States tax purposes,
or a foreign person 50% or more of whose gross income from all sources for
certain periods is effectively connected with a United States trade or
business, or, in addition, for periods after December 31, 2000, a foreign
partnership that at any time during its tax year either is engaged in the
conduct of a trade or business in the United States or has as partners one or
more United States persons that, in the aggregate hold more than 50% of the
income or capital interest in the partnership, such payments will be subject to
information reporting, but not backup withholding, unless such broker has
documentary evidence in its records that the holder is a Non-U.S. holder and
certain other conditions are met or the holder otherwise establishes an
exemption.

   Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder will be allowed as a refund or a credit against such Non-U.S.
Holder's U.S. federal income tax liability, provided that the requisite
procedures for claiming such refund or credit are followed.

   The preceding discussion of material United States federal income tax
consequences is for general information only and is not tax advice.
Accordingly, each investor should consult its own tax advisers as to particular
U.S. federal, state, local, foreign and other tax consequences to it of
purchasing, holding and disposing of our notes, including the applicability and
effect of any state, local or foreign tax laws, and of any proposed changes in
applicable laws.

                              PLAN OF DISTRIBUTION

   We will receive no proceeds in connection with the exchange offer.

   Each broker-dealer that receives new notes for its own account in connection
with the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of new notes. This prospectus, as it may be amended
or supplemented from time to time, may be used by a broker-dealer in connection
with resales of new notes received in exchange for old notes where the old
notes were acquired as a result of market-making activities or other trading
activities. We have agreed that for a period ending upon the earlier of
(1) 180 days after the exchange offer has been completed and (2) the date on
which broker-dealers no longer own any Transfer Restricted Securities, we will
make available and provide promptly upon reasonable request this prospectus as
amended or supplemented, in a form meeting the requirements of the Securities
Act to any broker-dealer for use in connection with any resale.

   New notes received by broker-dealers for their own account in 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

                                       96
<PAGE>

writing of options on the new notes or a combination of these methods of
resale, at market prices prevailing at the time of resale, at prices related to
prevailing market prices or negotiated prices. Any resale may be made directly
to purchasers or through brokers or dealers who may receive compensation in the
form of commissions or concessions from any broker-dealer and/or the purchasers
of any new notes. Any broker-dealer that resells new notes that were received
by it for its own account in the exchange offer and any broker or dealer that
participates in a distribution of new notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, and any profit on any
such resale of new notes and any commissions or concessions received by these
persons may be deemed to be underwriting compensation under the Securities Act.
The letter of transmittal states that by acknowledging that it will deliver,
and by delivering, a prospectus, a broker-dealer will not be deemed to admit
that it is an "underwriter" within the meaning of the Securities Act. We have
agreed to indemnify broker-dealers against various liabilities, including
liabilities under the Securities Act.

                                 LEGAL MATTERS

   The validity of the notes offered by this prospectus will be passed upon on
behalf of Exodus by Fenwick & West LLP, Palo Alto, California, and Winthrop,
Stimson, Putnam & Roberts, New York City, New York.

                    REPORT OF KPMG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Exodus Communications, Inc.:

   We have audited the accompanying supplemental consolidated balance sheets of
Exodus Communications, Inc. and subsidiaries (the Company) as of December 31,
1997 and 1998, and the related supplemental consolidated statements of
operations, stockholders' (deficit) equity and cash flows for each of the years
in the three-year period ended December 31, 1998. In connection with our audits
of the supplemental consolidated financial statements, we have also audited the
supplemental financial statement schedule as listed in the index on page F-1.
These supplemental consolidated financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these supplemental consolidated financial
statements and financial statement schedule based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   The supplemental consolidated financial statements and related supplemental
financial statement schedule give retroactive effect to the merger of the
Company and Service Metrics, Inc. on November 23, 1999, which has been
accounted for as a pooling of interests as described in Note 2 to the
supplemental consolidated financial statements. Generally accepted accounting
principles proscribe giving effect to a consummated business combination
accounted for by the pooling-of-interests method in financial statements that
do not include the date of consummation. These supplemental consolidated
financial statements do not extend through the date of consummation. However,
they will become the historical consolidated financial statements of the
Company after financial statements covering the date of consummation of the
business combination are issued.

   In our opinion, the supplemental consolidated financial statements referred
to above present fairly, in all material respects, the financial position of
Exodus Communications, Inc. and subsidiaries as of December 31, 1997 and 1998,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1998, in conformity with generally
accepted accounting principles applicable after financial statements are issued
for a period which includes the date of consummation of the business
combination. Also, in our opinion, the related supplemental financial statement
schedule, when considered in relation to the supplemental consolidated
financial statements taken as a whole, presents fairly, in all material
respects, the information set forth therein.

            NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS

        December 31, 1996, 1997 and 1998 and September 30, 1998 and 1999
      (Information as of September 30, 1999 and for the nine months ended
                   September 30, 1998 and 1999 is unaudited)

(1) Summary of the Company and Significant Accounting Policies

The Company

   Exodus Communications, Inc. ("Exodus" or "the Company") is a leading
provider of Internet system and network management solutions and technology
professional services for enterprises with mission-critical Internet
operations.

   The accompanying supplemental consolidated financial statements include the
accounts of the Company and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

Basis of Presentation

   The supplemental consolidated financial statements have been prepared to
give retroactive effect to the merger with Service Metrics, Inc. ("SMI" or
"Service Metrics") on November 23, 1999. The consolidated financial statements
have been restated for all periods presented as if SMI and the Company had
always been combined. Generally accepted accounting principles proscribe giving
effect to a consummated business combination accounted for by the pooling-of-
interests method in financial statements that do not include the date of
consummation. These supplemental financial statements do not extend through the
date of consummation; however, they will become the historical consolidated
financial statements of the Company after financial statements covering the
date of consummation of the business combination are issued.

   In recording the pooling-of-interests combination, the Company's
consolidated statement of operations for the year ended December 31, 1998 has
been combined with SMI's statement of operations for the period from May 19,
1998 ("inception") through December 31, 1998. The Company's consolidated
statements of operations for the nine-month periods ended September 30, 1998
and 1999 have been combined with SMI's statements of operations for the period
from inception through September 30, 1998, and the nine-month period ended
September 30, 1999, respectively. The consolidated balance sheets of the
Company as of December 31, 1998 and September 30, 1999, have been combined with
the balance sheets of Service Metrics as of the same dates.

   Service Metrics, which was incorporated in May 1998, is a leading provider
of Internet monitoring applications and services that measure the consistency,
availability and performance of Web sites. SMI is based in Boulder, Colorado,
and had 79 employees as of November 1999.

   In connection with the merger, the former shareholders and option holders of
SMI common stock received shares and options of Exodus common stock at the rate
of approximately 0.252 shares of Exodus common stock for each share of SMI
common stock. The Company issued a total of approximately 6,200,000 shares of
Exodus common stock in exchange for all outstanding shares of SMI common stock
and reserved approximately 760,000 shares of common stock for issuance upon the
exercise of SMI options the Company assumed pursuant to the merger agreement.

                   September 30, 1998 and 1999 is unaudited)


   As SMI was incorporated in May 1998, supplemental results of operations for
the periods ended December 31, 1996 and 1997 are the same as Exodus' results of
operations. The results of operations previously reported by the separate
companies and the combined amounts presented in the supplemental consolidated
financial statements are summarized below.

Use of Estimates

   The preparation of supplemental consolidated 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 supplemental consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

Revenue Recognition

   The Company's revenues consist of (i) monthly fees from customer use of
Internet Data Center sites, network services, managed services, and
professional services and use of equipment and software provided by the
Company, (ii) revenues from sales of third-party equipment to customers and
(iii) fees for installation and certain professional services. Currently,
substantially all of the Company's revenue is derived from services. Revenues
(other than installation fees, equipment sales to customers and certain
professional services) are generally billed and recognized ratably over the
term of the contract, which is generally one year. Installation fees are
typically recognized at the time the installation occurs, and equipment
revenues are typically recognized when the equipment is delivered to the
customer or placed into service at an Internet Data Center. The Company sells
third-party equipment to its customers as an accommodation to facilitate their
purchase of services. One-time professional service fees are typically
recognized when services are rendered.

Cash Equivalents and Investments

   Cash equivalents consist of highly liquid investments with original
maturities of 90 days or less. As of September 30, 1999, cash equivalents
consisted principally of money market funds at four financial institutions.

   The Company classifies its investments as "held-to-maturity." As of
September 30, 1999, such investments consisted of U.S. Treasury Notes and are
recorded at amortized cost.

   See Notes 4 and 6 for additional information regarding restricted cash
equivalents and investments.

Financial Instruments and Concentration of Credit Risk

   The carrying value of the Company's financial instruments, including cash
and cash equivalents, investments, accounts receivable, bank borrowings and
debt approximates fair market value. Financial instruments that potentially
expose the Company to a concentration of credit risk principally consist of
cash and cash equivalents, investments and accounts receivable.

   The Company's customer base is primarily composed of businesses throughout
the United States. The Company performs ongoing credit evaluations of its
customers and maintains reserves for potential losses.

Property and Equipment

   Property and equipment are stated at cost and depreciated on a straight-line
basis over their respective estimated useful lives, which are generally three
to five years. Equipment recorded under capital leases and leasehold
improvements are amortized using the straight-line method over the shorter of
the respective lease term or estimated useful life of the asset.

Software Development Costs

   The Company capitalizes software development costs incurred to develop
certain of the Company's collaborative system management services that are
included in the Company's co-location services in accordance with Statement of
Financial Accounting Standards (SFAS) No. 86, Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed. Costs are
capitalized after technological feasibility is achieved; generally upon the
development of a working model. To date, software development costs
capitalizable under SFAS No. 86 have not been material.

Income Taxes

   The Company uses the asset and liability method of accounting for income
taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the

financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to affect
taxable income. Valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be recovered.

Stock-Based Compensation

   The Company uses the intrinsic value-based method to account for all of its
employee stock-based compensation plans. Expense associated with stock-based
compensation is being amortized consistent with the method described in
Financial Accounting Standards Board (FASB) Interpretation No. 28 over the
vesting period of the individual options.

Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of

   The Company evaluates its long-lived assets, including goodwill and certain
identifiable intangibles, for impairment whenever events or changes in
circumstances indicate that the carrying amount of such assets or intangibles
may not be recoverable. Recoverability of assets to be held and used is
measured by a comparison of the carrying amount of an asset to future net cash
flows expected to be generated by the asset. If such assets are considered to
be impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair
value less costs to sell.

Unaudited Interim Financial Statements

   The accompanying unaudited supplemental consolidated interim financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information. In the opinion of management, the
accompanying unaudited supplemental consolidated financial statements have been
prepared on the same basis as the audited supplemental consolidated financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the Company's financial
position as of September 30, 1999, and the results of its operations and its
cash flows for the nine-month periods ended September 30, 1998 and 1999.

Goodwill and Other Intangible Assets

   Goodwill and other intangible assets are comprised primarily of amounts
recorded in business acquisitions and are included in intangibles and other
assets on the accompanying supplemental consolidated balance sheets. The
goodwill and other intangible amounts related to the acquisitions are being
amortized on a straight-line basis over periods generally ranging from 5 to 10
years (see Note 2).

(2) Business Combinations

   On October 2, 1998, the Company purchased substantially all of the assets,
including customer agreements, and assumed certain liabilities of Arca
Systems, Inc. ("Arca"), a wholly owned subsidiary of Cyberguard Corporation.
Arca, which has been in business for more than 10 years, is a provider of
advanced network and system security consulting services and designs and
develops security technology solutions for complex and sensitive information
systems. Arca operates as a wholly owned subsidiary of the Company. Total
consideration paid, including direct acquisition costs, aggregated
approximately $5,800,000. The acquisition was accounted for as a purchase and
the results of Arca have been included from the acquisition date. The excess
of the purchase price over the fair value of tangible net assets acquired
amounted to approximately $5,000,000 and was attributed primarily to workforce
in place ($2,500,000) and goodwill ($2,400,000). These amounts are generally
being amortized on a straight-line basis over 10 years.

   On February 1, 1999, the Company purchased all of the capital stock of
American Information Systems, Inc ("AIS"). AIS provides co-location services
as well as professional services. Total

                   September 30, 1998 and 1999 is unaudited)

consideration paid, including direct acquisition costs, aggregated
approximately $20,500,000. The acquisition was accounted for as a purchase with
the results of AIS included from the acquisition date. The excess of the
purchase price over the fair value of tangible net assets acquired amounted to
approximately $18,700,000 and was attributed primarily to goodwill
($15,000,000), customer lists ($3,200,000) and assembled workforce ($500,000).
These amounts are being amortized on a straight-line basis over periods ranging
from 5 to 7 years.

   On July 27, 1999, the Company completed its acquisition of Cohesive
Technology Solutions, Inc. ("Cohesive"). Cohesive offers a variety of services
including network design and development, Internet-based and application
development and information technology strategy and project management.
Pursuant to the terms of the Agreement and Plan of Reorganization, each share
of Cohesive common stock was converted into the right to receive 0.10488 shares
of Exodus common stock and $1.338 in cash; each share of Cohesive Series A
preferred stock was converted into the right to receive $122.337 in cash; each
share of Cohesive Series B preferred stock was converted into the right to
receive $115.965 in cash; each share of Cohesive Series C preferred stock was
converted into the right to receive $5.00 in cash; and each share of Cohesive
Series D preferred stock, which automatically converted into Cohesive common
stock immediately prior to the merger, was converted into the right to receive
0.10488 shares of Exodus common stock and approximately $6.655 in cash. In
addition, the Company assumed each issued and outstanding option to purchase
shares of Cohesive common stock which was converted into an option to purchase
Exodus common stock using an exchange ratio of 0.14604.

   Pursuant to the exchange ratios applied in the acquisition, the Company
issued 1,600,796 shares of Exodus common stock and paid approximately
$50,000,000 in cash and assumed options to purchase a total of 408,712 shares
of Exodus common stock for a total purchase price of approximately
$112,000,000. Of the cash consideration, $10,000,000 was deposited in an escrow
account to secure and collateralize the indemnification obligations of Cohesive
stockholders to Exodus and certain affiliates of Exodus. The acquisition was
accounted for as a purchase with the results of Cohesive included from the
acquisition date. The excess of the purchase price over the fair value of
tangible net assets acquired amounted to approximately $107,900,000 and was
attributed primarily to goodwill ($69,300,000), customer lists ($32,300,000)
and workforce in place ($6,300,000). These amounts are being amortized on a
straight-line basis over periods ranging from 5 to 8 years.

   The following summary, prepared on an unaudited pro forma basis, combines
the Company's supplemental consolidated results of operations with Arca's,
AIS', and Cohesive's results of operations, as if Arca, AIS, and Cohesive had
been acquired as of January 1, 1997 (in thousands, except per share data):

   The pro forma results are not necessarily indicative of what would have
occurred if the acquisitions had been in effect for the periods presented. In
addition, they are not intended to be a projection of future results and do not
reflect any synergies that might be achieved from combined operations.

   In November 1999, the Company agreed to acquire Global OnLine Japan Co.,
Ltd., an Internet solutions provider based in Tokyo. The transaction is
expected to close by the end of December 1999 and will be accounted for as a
purchase.

("Original Senior Notes") due 2008 for aggregate net proceeds of approximately
$193,400,000 (net of discounts to the initial purchasers and offering
expenses). Interest is payable semiannually on January 1 and July 1 of each
year commencing January 1, 1999. As of December 31, 1998, restricted cash

July 1999. Subject to significant exceptions, the Original Senior Notes
indenture restricts, among other things, the Company's ability to incur
additional indebtedness and the use of proceeds therefrom, pay dividends, make
certain other restricted payments, incur certain liens to secure indebtedness
or engage in merger transactions.

                   September 30, 1998 and 1999 is unaudited)


   On March 3, 1999, the Company issued $250,000,000 of 5% Convertible
Subordinated Notes due March 15, 2006 (the "Convertible Notes") for aggregate
net proceeds of approximately $242,100,000 (net of offering expenses). Proceeds
from the sale of the Convertible Notes may be used only for limited purposes.
Proceeds in the amount of $48,500,000 may be used for general corporate
purposes. The remaining $193,600,000 may be used only to finance the purchase
of assets or other businesses to be used in the Company's business.

   The Convertible Notes are convertible into the Company's common stock at a
conversion rate of 87.5704 shares per $1,000 principal amount of Convertible
Notes, subject to adjustment in certain events and at each holder's option. The
Convertible Notes will not be subject to redemption prior to March 20, 2001,
and generally will be redeemable on or after that date at the option of the
Company, at the redemption prices set forth in the indenture to the Convertible
Notes ("Convertible Notes Indenture"), subject to certain provisions. In the
event of a Change in Control (as defined in the Convertible Notes Indenture),
each holder of the Convertible Notes has the right, subject to certain
conditions and restrictions, to require the Company to repurchase all or any
part of the holder's Convertible Notes at a repurchase price of 100% of the
principal amount, plus accrued interest of the Convertible Notes being
repurchased. Interest on the Convertible Notes is payable on March 15 and
September 15 of each year, commencing on September 15, 1999. Accordingly, the
Company made its first interest payment in the amount of approximately
$6,700,000 on September 15, 1999. The Convertible Notes are unsecured
obligations of the Company and are subordinated to all existing and future
Senior Indebtedness (as defined in the Convertible Notes Indenture) and
effectively subordinated to all indebtedness and other liabilities of the
Company's subsidiaries.

   On June 22, 1999, the Company issued an additional $75,000,000 of Senior
Notes due 2008 ("Additional Senior Notes") at 100.50% plus accrued interest, if
any, from June 22, 1999, for aggregate net proceeds of approximately
$73,200,000 (net of offering expenses). The Company issued the Additional
Senior Notes under the indenture dated July 1, 1998 under which it previously
issued the Original Senior Notes discussed above. The Additional Senior Notes
will be subject to substantially the same terms and conditions as the Original
Senior Notes. Interest is payable semi-annually on January 1 and July 1 of each
year commencing July 1, 1999. Concurrent with the closing of the offering, the
Company deposited approximately $8,400,000 with an escrow agent that would be
sufficient to pay when due the first three interest payments. An interest
payment of approximately $211,000 was made on July 1, 1999 representing
interest from June 22, 1999 to July 1, 1999.

   On July 22, 1999, the Company amended its revolving line of credit agreement
with a financial institution, increasing the total commitment amount from
$7,000,000 to $10,000,000. Pursuant to the terms of the new amendment, the line
of credit can be used for working capital requirements, foreign exchange
forward contracts, and letters of credit. The amount available for working
capital borrowings is limited to $4,000,000. In addition, total foreign
exchange contracts at any one time cannot exceed 10 times the amount of the
foreign exchange sublimit, which is a maximum of $1,000,000. The line of credit
will expire in July 2000 and is subject to certain covenants.

    line basis through the commitment periods of the credit facilities.

  . The 480,000 warrants issued in connection with the strategic alliance for
    which the value was determined to be $525,000. This amount was recorded

    consolidated statement of operations for the year ended December 31,
    1998.

Convertible Preferred Stock of Service Metrics, Inc.

   In May 1998, SMI issued 540,936 shares of Series A convertible preferred
stock for approximately $1,000,000 in cash. In December 1998, SMI issued
1,012,222 shares of Series B convertible preferred stock for approximately
$5,000,000 in cash. In January 1999, SMI issued an additional 303,667 shares of
Series B convertible preferred stock for approximately $1,500,000 in cash. In
July 1999, SMI issued 728,953 shares of Series C convertible preferred stock
for approximately $8,000,000 in cash.

   The Series A, B, and C convertible preferred stock ("SMI Preferred Stock")
was convertible, at the option of the holder, into common stock of SMI based on
formulas specified in the preferred stock agreements. The SMI Preferred Stock
would automatically convert into common stock upon the closing of an initial
public offering of SMI, where the net cash proceeds were at least $15,000,000
and the public offering price would be at least $2.50 per share. The holders of
the SMI Preferred Stock were entitled to receive dividends at the rate of $0.16
for Series A, $0.48 for Series B, and $1.10 for Series C, when and if declared
by the Board of Directors. These dividends were noncumulative. Holders of the
SMI preferred stock were entitled to vote upon any matter submitted to the
stockholders for a vote and have one vote for each full share of common stock
into which their SMI Preferred Stock would be converted at the date of the
vote. The SMI Preferred Stock had liquidation privileges generally equal to the
SMI Preferred Stock purchase price per share plus any declared but unpaid
dividends and was in preference to shares of common stock.

   In connection with the merger between Exodus and SMI on November 23, 1999,
all of the SMI preferred shareholders converted their SMI Preferred Stock into
SMI common stock which was converted into Exodus Common Stock based on a
specified exchange ratio.

Initial Public Offering

   On March 24, 1998, the Company completed its initial public offering ("IPO")
of 41,000,000 shares of its common stock. Net proceeds to the Company, after
deducting underwriting discounts and commissions and offering expenses,
aggregated approximately $69,800,000. At the closing of the IPO, all redeemable
convertible preferred stock was converted to common stock and all warrants to
purchase redeemable convertible preferred stock were converted to warrants to
purchase common stock on a one-for-three basis. In connection with the IPO,
certain warrant holders exercised their warrants to purchase redeemable
convertible preferred stock (which converted into common stock), which resulted
in additional proceeds of $1,842,000.

Stock Purchase and Stock Option Plans

   During 1995, the Company adopted a Stock Purchase Plan under which 2,933,336
shares of common stock were authorized. Awards totaling 858,944 shares of
common stock were granted to individuals through 1996, at a price of $0.03 per
share, the estimated fair market value of the shares on the date of the award.
No awards were granted during the years ended December 31, 1997 and 1998.
Generally, the shares are subject to a 50-month vesting period. As of December
31, 1998, 34,408 shares remained unvested. Unvested shares are subject to
repurchase, at the Company's option, at the original purchase price upon a
participant's termination. Of the shares granted, 370,408 had been repurchased
by the Company as of December 31, 1998.

   In January 1998, the Company adopted the 1998 Employee Stock Purchase Plan
(the "Purchase Plan") and reserved a total of 4,800,000 shares of the Company's
common stock for issuance thereunder. The Purchase Plan permits eligible
employees to purchase common stock through payroll deductions at a purchase
price of 85% of the lower of the fair market value of the common stock on the
first day of the offering period or on the last day of the purchase period.
During 1998, 436,528 shares were issued under the Purchase Plan at a weighted-
average purchase price of $1.67 per share.

   In January 1997, the Company adopted the 1997 Equity Incentive Plan (the
"1997 Plan"), which served as the successor to the Company's 1995 Stock Option
Plan (the "1995 Plan"). Options granted under the 1995 Plan before its
termination continue to remain outstanding in accordance with their terms, but
no further options may be granted under the 1995 Plan. Options granted under
the 1995 Plan were granted with exercise prices not less than fair market value
at the date of grant as determined by the Board of Directors, generally vested
12% after 6 months from the date of grant and 2% per month thereafter, and
generally are exercisable for a term of 10 years after the date of grant. Under
the 1997 Plan, the Company reserved 17,600,000 shares of its common stock for
issuance to employees and consultants to be granted as either incentive or
nonqualified stock options. Options granted under the 1997 Plan generally vest
12% after 6 months from the date of grant and 2% per month thereafter and are
generally exercisable for a term of 10 years after the date of grant.

   In January 1998, the Company adopted the 1998 Equity Incentive Plan (the
"1998 Plan"). On the effective date of the Company's IPO, the 1998 Plan became
effective as the successor to the 1997 Plan. The Company has reserved
12,000,000 shares of common stock for issuance under the 1998 Plan in addition
to the shares that remain from the 1997 Plan. The 1998 Plan permits the grant
of either incentive or nonqualified stock options. Options granted under the
1998 Plan will have a maximum term of 10 years and generally will vest over 50
months. The 1998 Plan will terminate in January 2008.

   On June 2, 1999, the Company's stockholders approved an amendment to the
Company's 1998 Equity Incentive Plan to increase the number of shares of common
stock reserved for issuance thereunder by 8,000,000 shares, from 12,000,000
shares to 20,000,000 shares.

   In January 1998, the Company adopted the 1998 Directors Stock Option Plan
(the "Directors Plan") and reserved a total of 1,600,000 shares of the
Company's common stock for issuance thereunder. Each nonemployee director who
is or becomes a member of the Board of Directors on or after the effective date
of the Company's IPO, with certain limited exceptions, will initially be
granted an option for 40,000 shares of the Company's common stock and,
thereafter, an option to purchase an additional 10,000 shares of the Company's
common stock annually. Initial options granted under the Directors Plan will
vest as to 33 1/3% of the shares on each annual anniversary of the date of
grant. Annual grants will vest 25% on each annual anniversary of the date of
grant. The exercise price of the options granted under the Directors Plan will
be at the fair market value of the Company's common stock on the date of grant.

   In January 1998, the Company granted stock options to purchase 2,666,672
shares of common stock to an officer of the Company, of which half have an
exercise price of $1.13 per share and vest 100% after 3 years and half have an
exercise price of $2.25 per share and vest 100% after 5 years. The stock
options accelerate and become fully vested if the Company is acquired or sells
all or substantially all of its assets.

   In March 1998, the Company granted a stock option to an officer of the
Company to purchase 5,775,848 shares of common stock with an exercise price of
$1.13 per share (fair market value on the date of grant) that vests as to 12%
of such shares in September 1998 and vests as to an additional 2% per month
thereafter.

   In January 1999, the Company adopted the 1999 Stock Option Plan (the "1999
Plan"). Under the 1999 Plan, the Company has reserved 16,000,000 shares of
common stock for issuance to employees, consultants, and to be used for
acquisitions, to be granted as nonqualified stock options. Options granted
under the 1999 Plan generally will vest over 50 months and are generally
exercisable for a term of 10 years from the date of grant.

Service Metrics, Inc. Stock Option Plan

   In July 1998, the SMI Board of Directors adopted the 1998 Stock Option Plan.
Under the Plan, officers, employees and certain other individuals could be
granted options and rights to purchase shares of common stock. Options granted
could be either incentive stock options or non-statutory stock options. SMI had
reserved 512,624 shares of common stock for issuance of stock options. As of
December 31, 1998, 359,841 shares were available for future grant. Depending on
the type of option, the exercise price could not be less than the fair market
value per common share on the date of grant or as determined by the Board of
Directors. Options were exercisable over periods determined by the Board of
Directors, not to exceed 10 years, and generally were to vest ratably over 4
years. In the event of the termination of the optionee's relationship with SMI,
vested options yet to be exercised would remain exercisable for such period of
time ending on the earlier of 3 months after termination or the expiration of
the term of the option, or as determined by the Board of Directors.

   In connection with the merger between Exodus and SMI on November 23, 1999,
all of the SMI stock options were assumed by Exodus and converted into Exodus
stock options based on a specified exchange ratio.

Fair Value Disclosures

   The Company uses the intrinsic value method in accounting for its employee
stock-based compensation plans. Accordingly, no compensation cost has been
recognized for any of its stock options because the exercise price of each
option equaled or exceeded the fair value of the underlying common stock as of
the grant date for

each stock option, except for stock options granted by the Company from March
1997 through December 1997 and stock options granted by SMI from January 1999
to September 1999. With respect to the stock options granted by the Company
from March to December 1997, the Company recorded deferred stock compensation
of $3,482,000 for the difference at the grant date between the exercise price
and the fair value of the common stock underlying the options. With respect to
the stock options granted by SMI from January 1999 to September 1999, SMI
recorded deferred stock compensation of $2,778,000. These amounts are being
amortized consistent with the method described in FASB Interpretation No. 28
over the vesting period of the individual options, generally 48 to 50 months.
Had compensation cost been determined in accordance with SFAS No. 123 for all
of the Company's and SMI's stock-based compensation plans, net loss
attributable to holders of common stock and net loss per share would have been

Stockholder Rights Plan

   In January 1999, the Company adopted a Stockholder Rights Plan ("the Rights
Plan"). The Rights Plan is designed to protect the long-term value of the
Company for its stockholders during any future unsolicited acquisition
attempt. In connection with the Rights Plan, the Company declared a dividend
of one preferred share purchase right for each share of the Company's common
stock outstanding on February 11, 1999 ("Record Date") and further directed
the issuance of one such right with respect to each share of the Company's
common stock that is issued after the Record Date, except in certain
circumstances.

   On June 2, 1999, stockholders approved an amendment to the Company's
Restated Certificate of Incorporation to increase the authorized number of
shares of common stock issuable by the Company from 100,000,000 to 300,000,000.

Stock Splits

   On April 12, 1999 and August 12, 1999, the Company completed two-for-one
stock splits accomplished in the form of stock dividends. Share and per share
amounts in the accompanying supplemental consolidated financial statements
reflect both two-for-one stock splits retroactively.

(6)Commitments and Contingencies

Leases

   The Company has entered into a number of operating leases for its
facilities. The leases expire from 1999 through 2010. As of December 31, 1998,
the Company had collateralized letters of credit aggregating $3,238,000 for
these leases. The related funds are included in restricted cash equivalents and
investments on the accompanying supplemental consolidated balance sheet. The
Company also leases certain data center infrastructure and equipment under
capital leases. Certain of these capital leases were entered into as sales-
leaseback transactions. No gain or loss was recorded in any such transaction
due to the short holding period from the time the assets were purchased until
the time of the sale-leaseback. Future minimum lease payments as of December
31, 1998 are as follows (in thousands):

Telecommunications Agreements

   In September 1997, the Company entered into an agreement to obtain
telecommunications services for a period of 60 months with a minimum commitment
of $230,000 per month. In January 1999, this original agreement was replaced
with a new agreement for a period of 60 months with a minimum commitment of

   In July 1998, the Company entered into an agreement to obtain
telecommunications services for a period of 36 months with a minimum commitment
of approximately $500,000 per month.

   In August 1999 the Company entered into capacity purchase agreements. The
agreements provide for a total potential outlay of approximately $105,000,000
for fiber capacity and related maintenance covering approximately 25 years.

Royalty Agreement

   In April 1997, the Company entered into an agreement with a software company
under which the Company licensed certain software for a royalty based on 1% of
the Company's gross revenues. Royalty expenses related to this agreement have
not been significant to date.

   In March 1999, this agreement was replaced with a new agreement that
obligates the Company to make certain future payments for the use of the
software license. These payments are not expected to have a material effect on
the consolidated financial statements.

Contingencies

   The Company is engaged in certain legal actions arising in the ordinary
course of business. The Company believes that it has adequate legal defenses
and that the ultimate outcome of these actions will not have a material effect
on the Company's consolidated financial position and results of operations.

</TABLE>

   As of December 31, 1998, the Company has a net operating loss carryforward
for federal and state purposes of $94,961,000 and $48,753,000, respectively.
The difference between the federal and state net operating loss carryforward is
due to the 50% limitation of net operating loss carryforwards for state
purposes. The federal net operating loss carryforward will expire from 2011
through 2018. The state net operating loss carryforward will expire from 2001
through 2003.

   Gross deferred tax assets as of December 31, 1998 include approximately
$3,430,000 relating to the exercise of stock options, which will be credited to
equity when realized.

   The net change in the valuation allowance was an increase of $9,654,000 and
$28,458,000 for the years ended December 31, 1997 and 1998, respectively.

   Federal and state tax laws impose significant restrictions on the
utilization of net operating loss carryforwards in the event of a shift in the
ownership of the Company, which constitutes an "ownership change" as defined by
Internal Revenue Code, Section 382. The Company has not determined if an
ownership change, as defined, has occurred. The Company plans to compute exact
limitations upon realization of taxable earnings and associated utilization of
the net operating loss carryforwards.

(8) Segment Information

   The Company operates a number of Internet Data Centers throughout the United
States and one in Europe. The Company establishes these Internet Data Centers
using a consistent investment and operating model. As a result, the expected
long-term economic characteristics and financial performance are similar. In
particular, each data center provides the same Internet related services to a
similar type of customer who may locate its servers in multiple Internet Data
Centers. As a result, the Company believes these Internet Data Centers
represent one reportable segment under the aggregation criteria of SFAS No.
131, Disclosures about Segments of an Enterprise and Related Information.
Internet Data Center operations primarily include services such as server
infrastructure support, Internet connectivity, and managed services.

   With the acquisition of Cohesive on July 27, 1999, management began
reviewing financial information and business performance and allocating
resources based on both Internet Data Center operations and by professional
services, given Cohesive's expertise in networking, Internet-based applications
and technology solutions. As a result, the Company identified professional
services as an additional reportable segment. Professional services primarily
include services such as network design and development, Internet-based and
application development, and information technology strategy.

                    REPORT OF KPMG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Exodus Communications, Inc.:

   We have audited the accompanying consolidated balance sheets of Exodus
Communications, Inc. and subsidiaries (the Company) as of December 31, 1997 and
1998, and the related consolidated statements of operations, stockholders'
(deficit) equity, and cash flows for each of the years in the three-year period
ended December 31, 1998. In connection with our audits of the consolidated
financial statements, we have also audited the financial statement schedule as
listed in the index on page F-1. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements and financial
statement schedule based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Exodus
Communications, Inc. and subsidiaries as of December 31, 1997 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1998, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the consolidated financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        December 31, 1996, 1997 and 1998 and September 30, 1998 and 1999
      (Information as of September 30, 1999 and for the nine months ended

(1) Summary of the Company and Significant Accounting Policies

The Company

   Exodus Communications, Inc. ("Exodus" or "the Company") is a leading
provider of Internet system and network management solutions and technology
professional services for enterprises with mission-critical Internet
operations.

   The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation.

Use of Estimates

   The preparation of consolidated 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 consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

Revenue Recognition

   The Company's revenues consist of (i) monthly fees from customer use of
Internet Data Center sites, network services, managed services, and
professional services and use of equipment and software provided by the
Company, (ii) revenues from sales of third-party equipment to customers and
(iii) fees for installation and certain professional services. Currently,
substantially all of the Company's revenue is derived from services. Revenues
(other than installation fees, equipment sales to customers and certain
professional services) are generally billed and recognized ratably over the
term of the contract, which is generally one year. Installation fees are
typically recognized at the time the installation occurs, and equipment
revenues are typically recognized when the equipment is delivered to the
customer or placed into service at an Internet Data Center. The Company sells
third-party equipment to its customers as an accommodation to facilitate their
purchase of services. One-time professional service fees are typically
recognized when services are rendered.

Cash Equivalents and Investments

   Cash equivalents consist of highly liquid investments with original
maturities of 90 days or less. As of September 30, 1999 cash equivalents
consisted principally of money market funds at three financial institutions.

   The Company classifies its investments as "held-to-maturity." As of
September 30, 1999 such investments consisted of United States Treasury Notes
and are recorded at amortized cost.

   See Notes 4 and 6 for additional information regarding restricted cash
equivalents and investments.

Financial Instruments and Concentration of Credit Risk

   The carrying value of the Company's financial instruments, including cash
and cash equivalents, investments, accounts receivable, bank borrowings and
debt approximates fair market value. Financial instruments that potentially
expose the Company to a concentration of credit risk principally consist of
cash and cash equivalents, investments and accounts receivable.

   The Company's customer base is primarily composed of businesses throughout
the United States. The Company performs ongoing credit evaluations of its
customers and maintains reserves for potential losses.

Property and Equipment

   Property and equipment are stated at cost and depreciated on a straight-line
basis over their respective estimated useful lives, which are generally three
to five years. Equipment recorded under capital leases and leasehold
improvements are amortized using the straight-line method over the shorter of
the respective lease term or estimated useful life of the asset.

Software Development Costs

   The Company capitalizes software development costs incurred to develop
certain of the Company's collaborative systems management services that are
included in the Company's co-location services in accordance with Statement of
Financial Accounting Standards (SFAS) No. 86, Accounting for the Costs of
Computer Software to Be Sold, Leased, or Otherwise Marketed. Costs are
capitalized after technological feasibility is achieved; generally upon the
development of a working model. To date, software development costs
capitalizable under SFAS No. 86 have not been material.

Income Taxes

   The Company uses the asset and liability method of accounting for income
taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the

financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to affect
taxable income. Valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be recovered.

Stock-Based Compensation

   The Company uses the intrinsic value-based method to account for all of its
employee stock-based compensation plans. Expense associated with stock-based
compensation is being amortized consistent with the method described in
Financial Accounting Standards Board (FASB) Interpretation No. 28 over the
vesting period of the individual options.

Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of

   The Company evaluates its long-lived assets, including goodwill and certain
identifiable intangibles, for impairment whenever events or changes in
circumstances indicate that the carrying amount of such assets or intangibles
may not be recoverable. Recoverability of assets to be held and used is
measured by a comparison of the carrying amount of an asset to future net cash
flows expected to be generated by the asset. If such assets are considered to
be impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair
value less costs to sell.

Unaudited Interim Financial Statements

   The accompanying unaudited consolidated interim financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information. In the opinion of management, the accompanying
unaudited consolidated financial statements have been prepared on the same
basis as the audited consolidated financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for the
fair presentation of the Company's financial position as of September 30, 1999,
and the results of its operations and its cash flows for the nine-month periods
ended September 30, 1998 and 1999.

Goodwill and Other Intangible Assets

   Goodwill and other intangible assets are comprised primarily of amounts
recorded in business acquisitions and are included in intangibles and other
assets on the accompanying consolidated balance sheets. The goodwill and other
intangible amounts related to the acquisitions are being amortized on a
straight-line basis over periods generally ranging from 5 to 10 years (see Note
2).

(2) Business Combinations

   On October 2, 1998, the Company purchased substantially all of the assets,
including customer agreements, and assumed certain liabilities of Arca
Systems, Inc. ("Arca"), a wholly owned subsidiary of Cyberguard Corporation.
Arca, which has been in business for more than ten years, is a provider of
advanced network and system security consulting services and designs and
develops security technology solutions for complex and sensitive information
systems. Arca operates as a wholly owned subsidiary of the Company. Total
consideration paid, including direct acquisition costs, aggregated
approximately $5,800,000. The acquisition was accounted for as a purchase and
the results of Arca have been included from the acquisition date. The excess
of the purchase price over the fair value of tangible net assets acquired
amounted to approximately $5,000,000 and was attributed primarily to workforce
in place ($2,500,000) and goodwill ($2,400,000). These amounts are generally
being amortized on a straight-line basis over 10 years.

   On February 1, 1999, the Company purchased all of the capital stock of
American Information Systems, Inc ("AIS"). AIS provides co-location services
as well as professional services. Total consideration paid, including direct
acquisition costs, aggregated approximately $20,500,000. The acquisition was
accounted for as a purchase with the results of AIS included from the
acquisition

date. The excess of the purchase price over the fair value of tangible net
assets acquired amounted to approximately $18,700,000 and was attributed
primarily to goodwill ($15,000,000), customer lists ($3,200,000) and assembled
workforce ($500,000). These amounts are being amortized on a straight-line
basis over periods ranging from 5 to 7 years.

   On July 27, 1999, the Company completed its acquisition of Cohesive
Technology Solutions, Inc. ("Cohesive"). Cohesive offers a variety of services
including network design and development, Internet-based and application
development and information technology strategy and project management.
Pursuant to the terms of the Agreement and Plan of Reorganization, each share
of Cohesive common stock was converted into the right to receive 0.10488 shares
of Exodus common stock and $1.338 in cash; each share of Cohesive Series A
Preferred Stock was converted into the right to receive $122.337 in cash; each
share of Cohesive Series B Preferred Stock was converted into the right to
receive $115.965 in cash; each share of Cohesive Series C Preferred Stock was
converted into the right to receive $5.00 in cash; and each share of Cohesive
Series D Preferred stock, which automatically converted into Cohesive common
stock immediately prior to the merger, was converted into the right to receive
0.10488 shares of Exodus common stock and approximately $6.655 in cash. In
addition, the Company assumed each issued and outstanding option to purchase
shares of Cohesive common stock which was converted into an option to purchase
Exodus common stock using an exchange ratio of 0.14604.

   Pursuant to the exchange ratios applied in the acquisition, the Company
issued 1,600,796 shares of Exodus common stock and paid approximately
$50,000,000 in cash and assumed options to purchase a total of 408,712 shares
of Exodus common stock for a total purchase price of approximately
$112,000,000. Of the cash consideration, $10,000,000 was deposited in an escrow
account to secure and collateralize the indemnification obligations of Cohesive
stockholders to Exodus and certain affiliates of Exodus. The acquisition was
accounted for as a purchase with the results of Cohesive included from the
acquisition date. The excess of the purchase price over the fair value of
tangible net assets acquired amounted to approximately $107,900,000 and was
attributed primarily to goodwill ($69,300,000), customer lists ($32,300,000)
and workforce in place ($6,300,000). These amounts are being amortized on a
straight-line basis over periods ranging from 5 to 8 years.

   The following summary, prepared on an unaudited pro forma basis, combines
the Company's consolidated results of operations with Arca's, AIS', and
Cohesive's results of operations, as if Arca, AIS, and Cohesive had been
consummated as of January 1, 1997 (in thousands, except per share data):

("Original Senior Notes") due 2008 for aggregate net proceeds of approximately
$193,400,000 (net of discounts to the initial purchasers and offering
expenses). Interest is payable semi annually on January 1 and July 1 of each
year commencing January 1, 1999. As of December 31, 1998 restricted cash

July 1999. Subject to significant exceptions, the Original Senior Notes
Indenture restricts, among other things, the Company's ability to incur
additional indebtedness and the use of proceeds therefrom, pay dividends, make
certain other restricted payments, incur certain liens to secure indebtedness
or engage in merger transactions.

Convertible Notes will not be subject to redemption prior to March 20, 2001,
and generally will be redeemable on or after that date at the option of the
Company, at the redemption prices set forth in the indenture to the Convertible
Notes ("Convertible Notes Indenture"), subject to certain provisions. In the
event of a Change in Control (as defined in the Convertible Notes Indenture),
each holder of the Convertible Notes has the right, subject to certain
conditions and restrictions, to require the Company to repurchase all or any
part of the holder's Convertible Notes at a repurchase price of 100% of the
principal amount, plus accrued interest of the Convertible Notes being
repurchased. Interest on the Convertible Notes is payable on March 15 and
September 15 of each year, commencing on September 15, 1999. Accordingly, the
Company made its first interest payment in the amount of approximately
$6,700,000 on September 15, 1999. The Convertible Notes are unsecured
obligations of the Company and are subordinated to all existing and future
Senior Indebtedness (as defined in the Convertible Notes Indenture) and
effectively subordinated to all indebtedness and other liabilities of the
Company's subsidiaries.

   On June 22, 1999, the Company issued an additional $75,000,000 of Senior
Notes due 2008 ("Additional Senior Notes") at 100.50% plus accrued interest, if
any, from June 22, 1999, for aggregate net proceeds of approximately
$73,200,000 (net of offering expenses). The Company issued the Additional
Senior Notes under the Indenture dated July 1, 1998 under which it previously
issued the Original Senior Notes discussed above. The Additional Senior Notes
will be subject to substantially the same terms and conditions as the Original
Senior Notes. Interest is payable semi-annually on January 1 and July 1 of each
year commencing July 1, 1999. Concurrent with the closing of the offering, the
Company deposited approximately $8,400,000 with an escrow agent that would be
sufficient to pay when due the first three interest payments. An interest
payment of approximately $211,000 was made on July 1, 1999 representing
interest from June 22, 1999 to July 1, 1999.

   On July 22, 1999, the Company amended its revolving line of credit agreement
with a financial institution, increasing the total commitment amount from
$7,000,000 to $10,000,000. Pursuant to the terms of the new amendment, the line
of credit can be used for working capital requirements, foreign exchange
forward contracts, and letters of credit. The amount available for working
capital borrowings is limited to $4,000,000. In addition, total foreign
exchange contracts at any one time cannot exceed ten times the amount of the
foreign exchange sublimit, which is a maximum of $1,000,000. The line of credit
will expire in July 2000 and is subject to certain covenants.

option pricing model, with the following assumptions: dividends--none; expected
life--contractual term; risk-free interest rates of 5.7% to 6.7%; volatility--
60%, was not material except as follows:

  . The 1,579,011 warrants issued in connection with the sale of the Series C
    redeemable convertible preferred stock for which the fair value was
    determined to be $1,200,000. This amount was recorded as a reduction in

    line of credit facility and $5,000,000 equipment line of credit,
    respectively, for which the values were determined to be $530,000 and
    $200,000, respectively. These amounts are being amortized on a straight-
    line basis through the commitment periods of the credit facilities.

  . The 480,000 warrants issued in connection with the strategic alliance for
    which the value was determined to be $525,000. This amount was recorded
    as marketing and sales expense in the accompanying consolidated statement
    of operations for the year ended December 31, 1998.

   As of December 31, 1997 and 1998, the Company has 149,304 and 1,448,680
warrants to purchase common stock outstanding, respectively.

Initial Public Offering

   On March 24, 1998, the Company completed its initial public offering ("IPO")
of 41,000,000 shares of its common stock. Net proceeds to the Company, after
deducting underwriting discounts and commissions and offering expenses,
aggregated approximately $69,800,000. At the closing of the IPO, all redeemable
convertible preferred stock was converted to common stock and all warrants to
purchase redeemable convertible preferred stock were converted to warrants to
purchase common stock on a one-for-three basis. In connection with the IPO,
certain warrant holders exercised their warrants to purchase redeemable
convertible preferred stock (which converted into common stock), which resulted
in additional proceeds of $1,842,000.

Stock Purchase and Stock Option Plans

   During 1995, the Company adopted a Stock Purchase Plan under which 2,933,336
shares of common stock were authorized. Awards totaling 858,944 shares of
common stock were granted to individuals through 1996, at a price of $0.03 per
share, the estimated fair market value of the shares on the date of the award.
No awards were granted during the years ended December 31, 1997 and 1998.
Generally, the shares are subject to a 50-month vesting period. As of December
31, 1998, 34,408 shares remained unvested. Unvested shares are subject to
repurchase, at the Company's option, at the original purchase price upon a
participant's termination. Of the shares granted, 370,408 had been repurchased
by the Company as of December 31, 1998.

   In January 1998, the Company adopted the 1998 Employee Stock Purchase Plan
(the "Purchase Plan") and reserved a total of 4,800,000 shares of the Company's
common stock for issuance thereunder. The Purchase Plan permits eligible
employees to purchase common stock through payroll deductions at a purchase
price of 85% of the lower of the fair market value of the common stock on the
first day of the offering period or on the last day of the purchase period.
During 1998, 436,528 shares were issued under the Purchase Plan at a weighted-
average purchase price of $1.67 per share.

   In January 1997, the Company adopted the 1997 Equity Incentive Plan (the
"1997 Plan"), which served as the successor to the Company's 1995 Stock Option
Plan (the "1995 Plan"). Options granted under the 1995 Plan before its
termination continue to remain outstanding in accordance with their terms, but
no further options may be granted under the 1995 Plan. Options granted under
the 1995 Plan were granted with exercise prices not less than fair market value
at the date of grant as determined by the Board of Directors, generally vested
12% after 6 months from the date of grant and 2% per month thereafter, and
generally are exercisable for a term of 10 years after the date of grant. Under
the 1997 Plan, the Company reserved 17,600,000 shares of its common stock for
issuance to employees and consultants to be granted as either incentive or
nonqualified stock options. Options granted under the 1997 Plan generally vest
12% after 6 months from the date of grant and 2% per month thereafter and are
generally exercisable for a term of 10 years after the date of grant.

   In January 1998, the Company adopted the 1998 Equity Incentive Plan (the
"1998 Plan"). On the effective date of the Company's IPO, the 1998 Plan became
effective as the successor to the 1997 Plan. The Company has reserved
12,000,000 shares of common stock for issuance under the 1998 Plan in addition
to the shares that remain from the 1997 Plan. The 1998 Plan permits the grant
of either incentive or nonqualified stock options. Options granted under the
1998 Plan will have a maximum term of 10 years and generally will vest over 50
months. The 1998 Plan will terminate in January 2008.

   On June 2, 1999, the Company's stockholders approved an amendment to the
Company's 1998 Equity Incentive Plan to increase the number of shares of common
stock reserved for issuance thereunder by 8,000,000 shares, from 12,000,000
shares to 20,000,000 shares.

   In January 1998, the Company adopted the 1998 Directors Stock Option Plan
(the "Directors Plan") and reserved a total of 1,600,000 shares of the
Company's common stock for issuance thereunder. Each nonemployee director who
is or becomes a member of the Board of Directors on or after the effective date
of the Company's IPO, with certain limited exceptions, will initially be
granted an option for 40,000 shares of the Company's common stock and,
thereafter, an option to purchase an additional 10,000 shares of the Company's
common stock annually. Initial options granted under the Directors Plan will
vest as to 33 1/3% of the shares on each annual anniversary of the date of
grant. Annual grants will vest 25% on each annual anniversary of the date of
grant. The exercise price of the options granted under the Directors Plan will
be at the fair market value of the Company's common stock on the date of grant.

   In January 1998, the Company granted stock options to purchase 2,666,672
shares of common stock to an officer of the Company, of which half have an
exercise price of $1.13 per share and vest 100% after 3 years and half have an
exercise price of $2.25 per share and vest 100% after 5 years. The stock
options accelerate and become fully vested if the Company is acquired or sells
all or substantially all of its assets.

   In March 1998, the Company granted a stock option to an officer of the
Company to purchase 5,775,848 shares of common stock with an exercise price of
$1.13 per share (fair market value on the date of grant) that vests as to 12%
of such shares in September 1998 and vests as to an additional 2% per month
thereafter.

   In January 1999, the Company adopted the 1999 Stock Option Plan ("the 1999
Plan"). Under the 1999 Plan, the Company has reserved 16,000,000 shares of
common stock for issuance to employees, and consultants, and to be used for
acquisitions, to be granted as nonqualified stock options. Options granted
under the 1999 Plan generally will vest over 50 months and are generally
exercisable for a term of 10 years from the date of grant.

Fair Value Disclosures

   The Company uses the intrinsic value method in accounting for its employee
stock-based compensation plans. Accordingly, no compensation cost has been
recognized for any of its stock options because the exercise price of each
option equaled or exceeded the fair value of the underlying common stock as of
the grant date for each stock option, except for stock options granted by the
Company from March 1997 through December 1997. With respect to the stock
options granted by the Company from March to December 1997, the Company
recorded deferred stock compensation of $3,482,000 for the difference at the
grant date between the exercise price and the fair value of the common stock
underlying the options. This amount is being amortized consistent with the
method described in FASB Interpretation No. 28 over the vesting period of the
individual options, generally 50 months. Had compensation cost been determined
in accordance with SFAS No. 123 for all of the Company's stock-based
compensation plans, net loss attributable to common stockholders and net loss
per share would have been changed to the amounts indicated below (in thousands,
except per share data):

Stockholder Rights Plan

   In January 1999, the Company adopted a Stockholder Rights Plan ("the Rights
Plan"). The Rights Plan is designed to protect the long-term value of the
Company for its stockholders during any future unsolicited acquisition
attempt. In connection with the Rights Plan, the Company declared a dividend
of one preferred share purchase right for each share of the Company's common
stock outstanding on February 11, 1999 ("Record Date") and further directed
the issuance of one such right with respect to each share of the Company's
common stock that is issued after the Record Date, except in certain
circumstances.

Restated Certificate of Incorporation to increase the authorized number of
shares of Common Stock issuable by the Company from 100,000,000 to 300,000,000.

Stock Splits

   On April 12, 1999 and August 12, 1999, the Company completed two-for-one
stock splits accomplished in the form of stock dividends. Share and per share
amounts in the accompanying consolidated financial statements reflect both two-
for-one stock splits retroactively.

(6)Commitments and Contingencies

Leases

   The Company has entered into a number of operating leases for its
facilities. The leases expire from 1999 through 2010. As of December 31, 1998,
the Company had collateralized letters of credit aggregating $3,238,000 for
these leases. The related funds are included in restricted cash equivalents and
investments on the accompanying consolidated balance sheet. The Company also
leases certain data center infrastructure and equipment under capital leases.
Certain of these capital leases were entered into as sales-leaseback
transactions. No gain or loss was recorded in any such transaction due to the
short holding period from the time the assets were purchased until the time of
the sale-leaseback. Future minimum lease payments as of December 31, 1998 are
as follows (in thousands):

Telecommunications Agreements

   In September 1997, the Company entered into an agreement to obtain
telecommunications services for a period of 60 months with a minimum commitment
of $230,000 per month. In January 1999, this original agreement was replaced
with a new agreement for a period of 60 months with a minimum commitment of
$1,000,000 per month.

   In July 1998, the Company entered into an agreement to obtain
telecommunications services for a period of 36 months with a minimum commitment
of approximately $500,000 per month.

   In August 1999 the Company entered into capacity purchase agreements. The
agreements provide for a total potential outlay of approximately $105,000,000
for fiber capacity and related maintenance covering approximately 25 years.

Royalty Agreement

   In April 1997, the Company entered into an agreement with a software company
under which the Company licensed certain software for a royalty based on 1% of
the Company's gross revenues. Royalty expenses related to this agreement have
not been significant to date.

   In March 1999, this agreement was replaced with a new agreement that
obligates the Company to make certain future payments for the use of the
software license. These payments are not expected to have a material effect on
the consolidated financial statements.

Contingencies

   The Company is engaged in certain legal actions arising in the ordinary
course of business. The Company believes that it has adequate legal defenses
and that the ultimate outcome of these actions will not have a material effect
on the Company's financial position and results of operations.

</TABLE>

   As of December 31, 1998, the Company has a net operating loss carryforward
for federal and California purposes of $94,087,000 and $48,316,000,
respectively. The difference between the federal and California net operating
loss carryforward is due to the 50% limitation of net operating loss
carryforwards for California purposes. The federal net operating loss
carryforward will expire from 2011 through 2018. The California net operating
loss carryforward will expire from 2001 through 2003.

   Gross deferred tax assets as of December 31, 1998 include approximately
$3,430,000 relating to the exercise of stock options, which will be credited to
equity when realized.

   The net change in the valuation allowance was an increase of $9,654,000 and
$28,128,000 for the years ended December 31, 1997 and 1998, respectively.

   Federal and California tax laws impose significant restrictions on the
utilization of net operating loss carryforwards in the event of a shift in the
ownership of the Company, which constitutes an "ownership change" as defined by
Internal Revenue Code, Section 382. The Company has not determined if an
ownership change, as defined, has occurred. The Company plans to compute exact
limitations upon realization of taxable earnings and associated utilization of
the net operating loss carryforwards.

(8) Segment Information

   The Company operates a number of Internet Data Centers throughout the United
States and one in Europe. The Company establishes these Internet Data Centers
using a consistent investment and operating model. As a result, the expected
long term economic characteristics and financial performance are similar. In
particular, each data center provides the same Internet related services to a
similar type of customer who may locate its servers in multiple Internet Data
Centers. As a result, the Company believes these Internet Data Centers
represent one reportable segment under the aggregation criteria of Statement of
Financial Accounting Standards ("SFAS") No. 131, "Disclosures About Segments of
an Enterprise and Related Information." Internet Data Center operations
primarily include services such as server infrastructure support, Internet
connectivity, and managed services.

   With the acquisition of Cohesive on July 27, 1999, Management began
reviewing financial information and business performance and allocating
resources based on both Internet Data Center operations and by professional
services, given Cohesive's expertise in networking, Internet-based applications
and technology solutions. As a result, the Company identified professional
services as an additional reportable segment. Professional services primarily
include services such as network design and development, Internet-based and
application development, and information technology strategy.

   Financial information for the Company's reportable segments is presented

(9) Subsequent Events

   On November 23, 1999, the Company closed a merger with Service Metrics, Inc.
("SMI") pursuant to which Service Metrics became its wholly owned subsidiary.
SMI, which was incorporated in May 1998, is a leading provider of Internet
monitoring applications and services that measure the consistency, availability
and performance of web sites. SMI is based in Boulder, Colorado and has
79 employees as of November 1999.

   In connection with the merger, the former shareholders and option holders of
SMI common stock received shares and options of Exodus Common Stock at the rate
of approximately 0.252 shares of Exodus common stock for each share of SMI
common stock. The Company issued a total of approximately 6,200,000 shares of
Exodus Common Stock in exchange for all outstanding shares of SMI common stock
and reserved approximately 760,000 shares of Exodus Common Stock for issuance
upon the exercise of SMI options the Company assumed pursuant to the merger
agreement.

                          INDEPENDENT AUDITORS' REPORT

Board of Directors of
Cohesive Technology Solutions, Inc.:

   We have audited the accompanying consolidated balance sheets of Cohesive
Technology Solutions, Inc. (formerly Cohesive Network Systems, Inc.) and
subsidiaries as of December 31, 1997 and 1998, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Cohesive Technology Solutions,
Inc. and subsidiaries as of December 31, 1997 and 1998, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1998 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  Years Ended December 31, 1996, 1997 and 1998

1. Business and Significant Accounting Policies

   Business--The Company was incorporated in California in 1993 under the name
Global Internet Access Services, Inc. and reincorporated in Delaware in 1994,
subsequently changing its name to Cohesive Network Systems, Inc. During
September 1998, the Company merged with Business Technologies, Inc. and changed
its name to Cohesive Technology Solutions, Inc. Cohesive Technology Solutions,
Inc. and its wholly-owned subsidiaries (collectively, the "Company") are
primarily in the business of providing information technology related
consulting services to mid-tier customers and divisions of large corporations.
The Company has core competencies in the areas of business consulting,
application development and network integration.

   The Company has incurred a net loss of $10,235,000 for the year ended
December 31, 1998. In addition, the Company has a negative working capital of
$5,891,000 and an accumulated deficit of $2,755,000 as of December 31, 1998.
Approximately $3 million of the Company's preferred stock is redeemable in
September 1999 while another $10.4 million is redeemable in January 2000. The
Company believes, to the extent existing resources and anticipated revenues are
insufficient to fund the Company's planned activities, that additional debt or
equity financing will be available from its majority stockholder. This
stockholder has indicated that to the extent that the Company is otherwise
unable to meets it obligation to repay its existing credit line at maturity in
December 1999, it will make an investment in debt or equity securities of the
Company in an amount sufficient to permit the Company to meet such obligation
up to a maximum of $15 million. In addition, the stockholder has agreed, to the
extent that the Company may not have capital legally available for the payment
of redemption amounts otherwise due in January 2000 in respect to preferred
stock held by the stockholder, to extend the redemption date of such preferred
stock until at least May 2000.

   Consolidation--The consolidated financial statements include the accounts of
Cohesive Technology Solutions, Inc. and its wholly-owned subsidiaries. All
significant intercompany balances and transactions have been eliminated.

   Use of Estimates--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 and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   Concentrations of Credit Risk--Financial instruments that potentially
subject the Company to concentrations of credit risk consist of cash
equivalents and accounts receivable. The Company invests its excess cash in
money market accounts and highly liquid government securities. The Company's
accounts receivable are generally derived from sales to customers in the United
States which require information technology and networking services. The
Company maintains reserves for potential credit losses.

   Fair Value of Financial Instruments--As of December 31, 1997 and 1998, the
carrying amounts of cash and cash equivalents, accounts receivable and
borrowings under the Company's credit agreements approximate their respective
fair values.

   Cash and Cash Equivalents--Cash equivalents are short-term, highly liquid
cash investments with an original maturity of less than 90 days.

                   (Formerly Cohesive Network Systems, Inc.)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                  Years Ended December 31, 1996, 1997 and 1998

   Restricted Cash--Restricted cash represents cash in escrow related to the
divestiture of the Company's software development group and Internet services
division.

   Short-Term Investments--While the Company's practice is to hold securities
to maturity, the Company has classified all securities as available-for-sale
securities, as the sale of such securities may be required prior to maturity to
implement management strategies. The carrying value of securities is adjusted
to fair market value, with unrealized gains and losses, net of deferred taxes,
being excluded from earnings and reported as a separate component of
stockholders' equity. Cost is based on the specific identification method for
purposes of computing realized gains or losses. At December 31, 1997, the
difference between fair value and amortized cost was not significant.

   Inventory--Inventory consists primarily of computer hardware held for resale
and spare parts, and is stated at the lower of cost or market. Cost is
determined using the first-in, first-out method.

   Property and Equipment--Property and equipment are stated at cost.
Depreciation and amortization are computed using the straight-line method over
the estimated useful lives of the assets, which are generally two to five
years.

   Intangibles--Intangibles resulting from the acquisition of technology
service businesses are estimated by management to be primarily associated with
the acquired workforce and technological know-how. As a result of the limited
operating history of the entities acquired, the rapid technological changes
occurring in the industry and the intense competition for qualified engineering
professionals, recorded intangibles are amortized on the straight-line basis
over the estimated periods of benefit, generally two to seven years. At
December 31, 1997 and 1998, accumulated amortization was $2,493,000 and
$9,227,000, respectively.

   At each balance sheet date, the Company assesses the value of recorded
intangibles for possible impairment based upon a number of factors, including
turnover of the acquired workforce and the undiscounted value of expected
future operating cash flows in relation to its net investment in each
subsidiary. Since inception, the Company has not recorded any provisions for
possible impairment of intangible assets.

   Revenue Recognition--Revenue from services is recognized upon performance.
Revenue from hardware and software sales is recognized upon shipment.

   Stock-Based Compensation--The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees."

   Income Taxes--Deferred tax liabilities are recognized for future taxable
amounts and deferred tax assets are recognized for future deductions net of a
valuation allowance to reduce net deferred tax assets to amounts that are more
likely than not to be realized.

   Reclassifications--Certain prior year amounts have been reclassified to
conform to the current year presentation. Other than the reclassification of
redeemable preferred stock, these reclassifications had no effect on total
stockholders' equity or net income (loss). Redeemable preferred stock has been
reclassified from stockholders' equity to mezzanine equity to comply with SEC
reporting requirements.

                  Years Ended December 31, 1996, 1997 and 1998


   Recently Issued Accounting Standards--In June 1997, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards (SFAS) No.
130, "Reporting Comprehensive Income," which requires an enterprise to report,
by major components and as a single total, the change in its net assets during
the period from nonowner sources. The Company adopted SFAS No. 130 in 1998. The
Company's comprehensive income is the same as its net income (loss).

   In 1998, the AICPA issued a Statement of Position (SOP 98-1), which requires
companies to capitalize the costs incurred to develop and install software for
internal use. The Company adopted SOP 98-1 in 1998. Adoption of this statement
did not impact the Company's financial position, results of operations or cash
flows.

   The total purchase prices above consist of (i) nonrefundable cash payments
due on closing of the acquisition (approximately $18.1 million), (ii) 900,000
shares of Convertible Redeemable Series D preferred stock issued to the former
shareholders of Business Technologies, Inc. (valued at $7.7 million) and
(iii) probable amounts to be paid in cash to the former owners of the acquired
companies upon the attainment of certain performance criteria (the "Cash
Earnouts") (approximately $12.8 million). Of the Cash Earnouts, $9.3 million
were allocated to original purchase price as the performance criteria were
considered probable of occurring as of the acquisition date. The remaining of
Cash Earnouts were contingent upon continued employment and were recorded as
Acquisition Related Charges during the employment periods. As of December 31,
1998, no additional amounts are contingent upon continued employment.

   During 1996, 1997 and 1998, the Company recognized Acquisition Related

   As of December 31, 1998, accrued liabilities included $283,000 of unpaid
Acquisition Related Charges that will be paid in 1999.

   The acquisitions have been accounted for in accordance with the purchase
method of accounting and the accompanying consolidated financial statements
reflect the purchase price allocated to assets acquired and liabilities assumed
based upon their fair values as of the acquisition date. The $34.5 million
excess of the cash purchase price over the fair value of the net identifiable
assets has been allocated to intangibles. The Company's results of operations
include those of the acquired companies from their respective dates of
acquisition.

   On July 25, 1997, the Company sold a portion of its software development
group to an unrelated third party for $40 million. As of December 31, 1997, all
of the proceeds except $4 million were available for operations. The remaining
amount was placed in escrow. During 1998, this entire amount and the related
accrued interest of $124,000 were released from escrow. In connection with this
sale, the vesting of options held by employees of the software development
division were accelerated by one year. This resulted in the Company recognizing
$281,000 in stock compensation expense during fiscal 1997. The Company recorded
a gain of $38 million during 1997 related to this sale.

   On November 26, 1997, the Company sold its Internet services division to an
unrelated third party for $6 million. As of December 31, 1997, all of the
proceeds except $1,050,000 were available for operations. The $1,050,000 amount
was placed in escrow at the time of the sale and was recorded as a deferred
gain at December 31, 1997. Of this amount, $942,000 was released to the Company
and recognized as a gain on divestiture during 1998. The remaining $108,000 was
released to the third party purchaser. In connection with

gains of $3.9 million and $0.9 million during 1997 and 1998, respectively,
related to this sale.

   The operating results of the Internet services division have been segregated
from continuing operations and reported as discontinued operations in the
accompanying statement of operations. Revenues for the discontinued operations
were $3,721,000 and $3,805,000 for 1996 and 1997, respectively.

4. Lines of Credit

   The Company has a revolving line of credit from a bank that provides for
borrowings up to $15 million through December 31, 1999. Borrowings under the
line are secured by substantially all of the Company's assets and bear interest
at varying rates based upon the bank's prime or LIBOR rate on the date of
borrowing. In addition, the line of credit restricts the payment by the Company
of cash dividends or distributions on its common stock. The agreements require,
among other things, that the Company satisfy certain financial covenants. As of
December 31, 1998, the Company was in compliance with such covenants.

   As of December 31, 1997, the Company had two revolving lines of credit from
banks, which provided for borrowings up to $1,000,000 each through June 2,
1998, and July 1, 1998. All outstanding amounts were fully paid during 1998 and
the lines of credit were not renewed.

Additional Stock Plan Information

   As discussed in Note 1, the Company accounts for its stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board Opinion (APB) No. 25, "Accounting for Stock Issued to
Employees," and its related interpretations.

   SFAS No. 123, "Accounting for Stock-Based Compensation," requires the
disclosure of pro forma net income (loss) had the Company adopted the fair
value method since the Company's inception. Under SFAS No. 123, the fair value
of stock-based awards to employees is calculated through the use of option
pricing models, even though such models were developed to estimate the fair
value of freely tradable, fully transferable options without vesting
restrictions, which significantly differ from the Company's stock option
awards. These models also require subjective assumptions, including future
stock price volatility and expected time to exercise, which greatly affect the
calculated values.

   The Company's calculations were made using the minimum value method with the
following weighted average assumptions: expected life, one year following
vesting; risk free interest rate of 6%; and no dividends during the expected
term. The Company's calculations are based on a multiple award valuation
approach, and forfeitures are recognized as they occur. If the computed minimum
values of the Company's stock-based awards to employees had been amortized to
expense over the vesting period of the awards as specified under SFAS No. 123,
net income (loss) available to common stockholders would have been
$(5,226,000), $18,065,000 and $(10,562,000) in 1996, 1997 and 1998,
respectively. The estimated weighted-average minimum value per option as of the
grant date for the awards granted for the years ended December 31, 1996, 1997
and 1998 were $0.06, $0.24 and $0.47, respectively.

</TABLE>

   The Company has net operating loss carryforwards of approximately $2.3
million for state income tax purposes, which will expire in 2003. The Company
has deferred tax assets of approximately $1,444,000 and $2,521,000 as of
December 31, 1997 and 1998, respectively, resulting primarily from basis
differences in intangibles and other items. However, because realization of
these benefits depends on the generation of future taxable income, which is
subject to uncertainty, the Company has placed a full valuation allowance
against the deferred tax assets.

   The Tax Reform Act of 1986 and California Conformity Act of 1987 impose
substantial restrictions on the utilization of net operating losses in the
event of an "ownership change" as defined in the Internal Revenue Code. Any
such ownership change could significantly limit the Company's ability to
utilize its tax carryforwards.

8. Employee Benefit Plan

   The Company has a qualified employee salary savings plan (401(k) plan). The
401(k) plan allows the Company to make discretionary contributions of a certain
percentage of employees' contributions to the 401(k) plan. The Company made no
contributions during 1996 and 1997 and the Company made a $12,000 contribution
during 1998.

9. Commitments and Contingencies

   The Company leases its facilities under various operating leases that extend
through February 2003. Rental expense for the Company's facilities was
$356,000, $530,000 and $987,000, for 1996, 1997 and 1998, respectively.

   Future minimum operating lease payments at December 31, 1998 are
approximately as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                  Years Ended December 31, 1996, 1997 and 1998


   The Company is party to various litigation arising in the normal course of
its operations. In the opinion of management, the ultimate liability for these
matters, if any, will not have a material adverse effect on the Company's
financial position or results of operations.

10. Subsequent Events

   On April 21, 1999, the Company entered into a definitive agreement to be
acquired by Exodus Communications, Inc. (Exodus) for cash and common stock
valued at approximately $100 million. The acquisition is expected to close in
mid-1999, subject to regulatory review and approval. Upon closing of the
acquisition, the Company will exchange all outstanding preferred and common
stock for cash and shares of Exodus common stock at that date.

matters, if any, will not have a material adverse effect on the Company's
financial position or results of operations.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

   The following unaudited pro forma combined condensed financial statements
are presented for illustrative purposes only and are not necessarily indicative
of the combined results of operations for future periods or the results of
operations that actually would have been realized had Exodus and Cohesive been
a combined company during the specified periods. The unaudited pro forma
combined condensed financial statements, including the related notes, are
qualified in their entirety by reference to, and should be read in conjunction
with, the supplemental consolidated financial statements and related notes
thereto of Exodus and the historical consolidated financial statements and
related notes thereto of Cohesive, included elsewhere in this registration
statement.

   The following unaudited pro forma combined condensed financial statements
give effect to the merger between Exodus and Cohesive using the purchase method
of accounting. The pro forma combined condensed financial statements are based
on the audited and unaudited supplemental consolidated financial statements and
related notes of Exodus and the audited and unaudited historical consolidated
financial statements and related notes of Cohesive. The pro forma adjustments
are based on management's estimates of the value of the tangible and intangible
assets acquired. In addition, management is continuing to assess its
integration plans, which may result in further costs.

   The pro forma combined condensed statements of operations assume the merger
took place as of January 1, 1998 and combine Exodus' audited supplemental
consolidated statement of operations for the year ended December 31, 1998 and
unaudited supplemental consolidated statement of operations for the nine months
ended September 30, 1999, with Cohesive's audited historical statement of
operations for the year ended December 31, 1998 and unaudited historical
statement of operations for the seven-month period ended July 27, 1999,
respectively.

   A pro forma condensed balance sheet as of September 30, 1999 has not been
presented since the merger has already been reflected in such balance sheet.

Cohesive in exchange for approximately $50 million in cash and 1,600,796 shares
of Exodus common stock. In addition, Exodus issued options to purchase a total
of 408,712 shares of Exodus common stock in exchange for all issued and
outstanding Cohesive options.

   Under purchase accounting, the total purchase price was allocated to
Cohesive's assets and liabilities based on their relative fair values. The
amounts and components of the purchase price along with the allocation of the
purchase price to assets acquired were as follows (in thousands):

   The pro forma combined condensed statements of operations give effect to the
merger as if it had occurred at January 1, 1998. Cohesive's historical
statement of operations data for the nine months ended September 30, 1999
reflects its operating activity for the period January 1, 1999 through July 27,
1999, as Exodus acquired Cohesive on July 27, 1999.

   The following adjustments have been reflected in the unaudited pro forma
combined condensed statements of operations:

     (a) Adjustment to remove the amortization of historical goodwill and
  other intangible assets previously recorded by Cohesive and to record the
  amortization of goodwill and intangible assets resulting from the
  allocation of the Cohesive purchase price. The pro forma adjustment assumes
  goodwill and other intangible assets will be amortized on a straight-line
  basis over the following estimated lives:

     (b) To eliminate interest income earned by Exodus on cash paid at the
  date of the merger assuming a 5% interest rate which approximates the
  Company's actual rate of return during the periods presented.

     (c) To remove Cohesive's historical cumulative dividends and accretion
  on redeemable preferred stock which are settled in cash at the date of the
  merger.

     (d) To reflect the shares issued as consideration for the merger.

Item 20. Indemnification of Officers and Directors

   As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors to the Registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith
or that involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the Delaware General Corporation Law or (iv) for any
transaction from which the director derived an improper personal benefit. In
addition, as permitted by Section 145 of the Delaware General Corporation Law,
the Bylaws of the Registrant provide that: (i) the Registrant is required to
indemnify its directors and executive officers to the fullest extent permitted
by the Delaware General Corporation Law; (ii) the Registrant may, in its
discretion, indemnify other officers, employees and agents as set forth in the
Delaware General Corporation Law; (iii) upon receipt of an undertaking to repay
such advances if indemnification is determined to be unavailable, the
Registrant is required to advance expenses, as incurred, to its directors and
executive officers to the fullest extent permitted by the Delaware General
Corporation Law in connection with a proceeding (except if a determination is
reasonably and promptly made by the Board of Directors by a majority vote of a
quorum consisting of directors who were not parties to the proceeding or, in
certain circumstances, by independent legal counsel in a written opinion that
the facts known to the decision-making party demonstrate clearly and
convincingly that such person acted in bad faith or in a manner that such
person did not believe to be in, or not opposed to, the best interests of the
corporation); (iv) the rights conferred in the Bylaws are not exclusive and the
Registrant is authorized to enter into indemnification agreements with its
directors, officers and employees and agents; (v) the Registrant may not
retroactively amend the Bylaw provisions relating to indemnity; and (vi) to the
fullest extent permitted by the Delaware General Corporation Law, a director or
executive officer will be deemed to have acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the Registrant and, with respect to any criminal action or proceeding, to have
had no reasonable cause to believe that his or her conduct was unlawful if his
or her action is based on the records or books of account of the corporation or
on information supplied to him or her by officers of the corporation in the
course of their duties or on the advice of legal counsel for the corporation or
on information or records given or reports made to the corporation by
independent certified public accountants or appraisers or other experts.

   The Registrant's policy is to enter into indemnification agreements with
each of its directors and executive officers. The indemnification agreements
provide that directors and executive officers will be indemnified and held
harmless to the fullest possible extent permitted by law including against all
expenses (including attorneys' fees), judgments, fines and settlement amounts
paid or reasonably incurred by them in any action, suit or proceeding,
including any derivative action by or in the right of the Registrant, on
account of their services as directors, officers, employees or agents of the
Registrant or as directors, officers, employees or agents of any other company
or enterprise when they are serving in such capacities at the request of the
Registrant. The Registrant will not be obligated pursuant to the agreements to
indemnify or advance expenses to an indemnified party with respect to
proceedings or claims (i) initiated or brought voluntarily by the indemnified
party and not by way of defense, except with respect to a proceeding to
establish or enforce a right to indemnify under the indemnification agreements
or any other agreement or insurance policy or under the Registrant's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
indemnification, or authorized by the Board of Directors or as otherwise
required under Delaware statute or law, regardless of whether the indemnified
party is ultimately determined to be entitled to such indemnification, (ii) for
expenses and the payment of profits arising from the purchase and sale by the
indemnified paved and the relative fault of the Registrant and the director or
executive officer. No contribution is allowed to a person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act of 1933) from any person who was not found guilty of such
fraudulent misrepresentation.

                                      II-1

   The indemnification agreement requires a director or executive officer to
reimburse the Registrant for all expenses advanced only to the extent it is
ultimately determined that the director or executive officer is not entitled,
under Delaware law, the Bylaws, the indemnification agreement or otherwise, to
be indemnified for such expenses. The form of indemnification agreement
provides that it is not exclusive of any rights a director or executive officer
may have under the Certificate of Incorporation, Bylaws, other agreements, any
majority-in-interest vote of the stockholders or vote of disinterested
directors, Delaware law or otherwise.

   The indemnification provision in the Bylaws, and the form of indemnification
agreements entered into between the Registrant and its directors and executive
officers, may be sufficiently broad to permit indemnification of the
Registrant's executive officers and directors for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act").

   As authorized by the Registrant's Bylaws, the Registrant, with approval by
the Board, expects to purchase director and officer liability insurance.

   In addition, Mr. Mocarski is indemnified in certain circumstances by Fleet
Financial Group, Inc.

   See also the undertakings set out in response to Item 22.

Registration Statement regarding relevant indemnification provisions described

Item 22. Undertakings

   (a) 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 of 1933, as amended (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.

      (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;

                                      II-8
<PAGE>

     (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.

   (b) 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

   (c) 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.

   (d) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

   (e) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in this registration
statement shall be deemed to be a new registration statement relating to the
securities offered herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

     This Dollar Security is one of a duly authorized issue of Dollar Securities
of the Issuer designated as its Dollar Denominated 10 3/4% Senior Notes due 2009
(herein called the "Dollar Securities"), issued and to be issued under an
Indenture, dated as of December 1, 1999 (herein called the "Indenture", which
term shall have the meaning assigned to it in such instrument), among the Issuer
and Chase Manhattan Bank and Trust Company, National Association, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Issuer, the Trustee and the
Holders of the Dollar Securities and of the terms upon which the Dollar
Securities are, and are to be, authenticated and delivered.

month period beginning December 15 of the years indicated below:

                                                                      Redemption

2004                                                                    105.375%
2005                                                                    103.583%
2006                                                                    101.792%

     In addition, at any time prior to December 15, 2002, the Issuer may redeem
up to 35% of the aggregate Outstanding principal amount of the Dollar Securities
with the Net Cash Proceeds of one or more sales of Capital Stock (other than
Disqualified Stock) at a Redemption Price equal to 110.75% of the aggregate
principal amount thereof, plus accrued and unpaid interest thereon and
Liquidated Damages, if any, to the date of redemption; provided that at least
65% of the original principal amount of the Dollar Securities remains
Outstanding immediately following such redemption. In order to effect the
foregoing redemption, the Issuer must mail a notice of redemption no later than
45 days after the related sale of Capital Stock and must consummate such
redemption within 60 days of the closing of the sale of Capital Stock.
<PAGE>

     The Dollar Securities do not have the benefit of any sinking fund
obligations.

     In the event of redemption or purchase pursuant to an Offer to Purchase of
this Dollar Security in part only, a new Dollar Security or Dollar Securities
for the unredeemed or unpurchased portion hereof will be issued in the name of
the Holder hereof upon the cancellation hereof.

     If an Event of Default shall occur and be continuing, there may be declared
due and payable the principal amount of (together with accrued and unpaid
interest on) the Dollar Securities, in the manner and with the effect provided
in the Indenture.

     The Holder of this Dollar Security (and any Person that has a beneficial
interest in this Dollar Security) is entitled to the benefits of an Exchange and
Registration Rights Agreement, dated as of December 1, 1999, and as the same may
be amended from time to time (the "Exchange and Registration Rights Agreement"),
executed by the Issuer. The Exchange and Registration Rights Agreement provides
that Liquidated Damages will be payable by the Issuer on the Dollar Securities
for specified periods if the Issuer does not comply with certain of its
obligations thereunder. Issuer agrees to pay Liquidated Damages, if any,
accruing on this Dollar Security.

     The Indenture provides that, subject to certain conditions, if (i) certain
Net Cash Proceeds are available to the Issuer as a result of an Asset Sale or
(ii) a Change of Control occurs, the Issuer shall be required to make an Offer
to Purchase for all or a specified portion of the Dollar Securities.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securities under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and its consequences. Any such consent or
waiver by the Holder of this Dollar Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Dollar Security and of any
Dollar Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Dollar Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Dollar Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities, the Holders of not less than 25% in principal amount of the
Securities at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities at the
time Outstanding a direction inconsistent with such request and shall have
failed to institute any such
<PAGE>

proceeding for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Dollar Security
for the enforcement of any payment of principal hereof or any premium or
interest hereon on or after the respective due dates expressed herein (or, in
the case of redemption, on or after the Redemption Date or, in the case of any
purchase of this Dollar Security required to be made pursuant to an Offer to
Purchase, on the Purchase Date).

     No reference herein to the Indenture and no provision of this Dollar
Security or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest on this Dollar Security at the times, place and rate, and in
the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Dollar Security is registrable in the Security
Register, upon surrender of this Dollar Security for registration of transfer at
the office or agency of the Issuer in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Dollar Securities, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

     The Dollar Securities are issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Dollar
Securities are exchangeable for a like aggregate principal amount of Dollar
Securities of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Dollar Security for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this Dollar Security is registered as the owner
hereof for all purposes, whether or not this Dollar Security be overdue, and
neither the Issuer, the Trustee nor any such agent shall be affected by notice
to the contrary.

     Interest on this Dollar Security shall be computed on the basis of a 360-
day year of twelve 30-day months.

     All terms used in this Dollar Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

in accordance with the laws of the State of New York.

                                                                       -----

2004                                                                   105.375%

2005                                                                   103.583%

2006                                                                   101.792%

Disqualified Stock) at a Redemption Price equal to 110.75% of the aggregate
principal amount thereof, plus accrued and unpaid interest thereon and
Liquidated Damages, if any, to the date of redemption; provided that at least
65% of the original principal amount of the Euro Securities remains Outstanding

redemption, the Issuer must mail a notice of redemption no later than 45 days
after the related sale of Capital Stock and must consummate such redemption

<PAGE>

     The Euro Securities do not have the benefit of any sinking fund
obligations.

     In the event of redemption or purchase pursuant to an Offer to Purchase of
this Euro Security in part only, a new Euro Security or Euro Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

     If an Event of Default shall occur and be continuing, there may be declared
due and payable the principal amount of (together with accrued and unpaid
interest on) the Euro Securities, in the manner and with the effect provided in
the Indenture.

     The Holder of this Euro Security (and any Person that has a beneficial
interest in this Euro Security) is entitled to the benefits of an Exchange and
Registration Rights Agreement, dated as of December 1, 1999, and as the same may
be amended from time to time (the "Exchange and Registration Rights Agreement"),
executed by the Issuer.  The Exchange and Registration Rights Agreement provides
that Liquidated Damages will be payable by the Issuer on the Euro Securities for
specified periods if the Issuer does not comply with certain of its obligations
thereunder. Issuer agrees to pay Liquidated Damages, if any, accruing on this
Euro Security.

     The Indenture provides that, subject to certain conditions, if (i) certain
Net Cash Proceeds are available to the Issuer as a result of an Asset Sale or
(ii) a Change of Control occurs, the Issuer shall be required to make an Offer
to Purchase for all or a specified portion of the Euro Securities.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securities under the Indenture at
any time by the Issuer and the Trustee or Authentication Agent with the consent
of the Holders of a majority in aggregate principal amount of the Securities at
the time Outstanding.  The Indenture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the Securities
at the time Outstanding, on behalf of the Holders of all the Securities, to
waive compliance by the Issuer with certain provisions of the Indenture and
certain past defaults under the Indenture and its consequences.  Any such
consent or waiver by the Holder of this Euro Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Euro Security and
of any Euro Security issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Euro Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Euro Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or
authentication agent or for any other remedy thereunder, unless such Holder
shall have previously given the Trustee or Authentication Agent written notice
of a continuing Event of Default with respect to the Securities, the Holders of
not less than 25% in principal amount of the Securities at the time Outstanding
shall have made written request to the Trustee or Authentication Agent to
institute proceedings in respect of such Event of Default as Trustee or
Authentication Agent and offered the Trustee or Authentication Agent reasonable
indemnity and the Trustee or Authentication Agent shall not have received from
the Holders of a
<PAGE>

majority in principal amount of Securities at the time Outstanding a direction
inconsistent with such request and shall have failed to institute any such
proceeding for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Euro Security for
the enforcement of any payment of principal hereof or any premium or interest
hereon on or after the respective due dates expressed herein (or, in the case of
redemption, on or after the Redemption Date or, in the case of any purchase of
this Euro Security required to be made pursuant to an Offer to Purchase, on the
Purchase Date).

     No reference herein to the Indenture and no provision of this Euro Security
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Euro Security at the times, place and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Euro Security is registrable in the Security
Register, upon surrender of this Euro Security for registration of transfer at
the office or agency of the Issuer in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Euro Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Euro Securities are issuable only in registered form without coupons in
denominations of Euro 1,000 and any integral multiple thereof.  As provided in
the Indenture and subject to certain limitations therein set forth, Euro
Securities are exchangeable for a like aggregate principal amount of Euro
Securities of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Euro Security for registration of
transfer, the Issuer, the Trustee or Authentication Agent and any agent of the
Issuer or the Trustee or Authentication Agent may treat the Person in whose name
this Euro Security is registered as the owner hereof for all purposes, whether
or not this Euro Security be overdue, and neither the Issuer, the Trustee nor
Authentication Agent nor any such agent shall be affected by notice to the
contrary.

     Interest on this Euro Security shall be computed on the basis of a 360-day
year of twelve 30-day months.

     All terms used in this Euro Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
<PAGE>

     The Indenture and this Euro Security shall be governed by and construed in
accordance with the laws of the State of New York.

writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his

the Holders of Outstanding Securities entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities, provided that the Issuer may not set a record date for,
and the provisions of this paragraph shall not apply with respect to, the giving
or making of any notice,

                                      -25-
<PAGE>

declaration, request or direction referred to in the next paragraph. If not set

respect of any such matter referred to in the foregoing sentence, the record
date for any such matter shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 701)
prior to such first solicitation. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities on such record date, and no
other Holders, shall be entitled to take the relevant action, whether or not
such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities on such record date. Nothing in this paragraph shall be construed to
prevent the Issuer from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Issuer, at its own
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities entitled to join in the giving or making
of (i) any Notice of Default, (ii) any declaration of acceleration referred to
in Section 502, (iii) any request to institute proceedings referred to in
Section 507(2) or (iv) any direction referred to in Section 512.  If any record
date is set pursuant to this paragraph, the Holders of Outstanding Securities on
such record date, and no other Holders, shall be entitled to join in such
notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of Outstanding Securities on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting
a new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities on the date such action is taken. Promptly after any record date is
set pursuant to this paragraph, the Trustee, at the Issuer's expense, shall
cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Issuer in writing and to each
Holder of Securities in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities in the manner set forth in Section 106, on or prior
to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this

                                      -26-
<PAGE>

Section, the party hereto which set such record date shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

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

postage prepaid, to each Holder affected by such event, at his address as it
appears in the Security Register, not later than the latest date (if any), and
not earlier than the earliest date (if any), prescribed for the giving of such
notice, with a copy to the Trustee at the same time mailed or delivered in
accordance with Section 105(1) hereof.  In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

foregoing redemption, the Issuer must mail a notice of redemption no later than
45 days after the related sale of Capital Stock and must consummate such
redemption within 60 days of the closing of the sale of Capital Stock.

     The Dollar Securities do not have the benefit of any sinking fund

     In the event of redemption or purchase pursuant to an Offer to Purchase of
this Dollar Security in part only, a new Dollar Security or Dollar Securities
for the unredeemed or unpurchased portion hereof will be issued in the name of
the Holder hereof upon the cancellation hereof.

     If an Event of Default shall occur and be continuing, there may be declared

interest on) the Dollar Securities, in the manner and with the effect provided
in the Indenture.

     [IF DOLLAR SECURITY IS A RESTRICTED SECURITY, THEN INSERT -- The Holder of

Dollar Security) is

<PAGE>

entitled to the benefits of an Exchange and Registration Rights Agreement, dated
as of December 1, 1999, and as the same may be amended from time to time (the
"Exchange and Registration Rights Agreement"), executed by the Issuer. The
Exchange and Registration Rights Agreement provides that Liquidated Damages will
be payable by the Issuer on the Dollar Securities for specified periods if the
Issuer does not comply with certain of its obligations thereunder. Issuer agrees
to pay Liquidated Damages, if any, accruing on this Dollar Security.]

     The Indenture provides that, subject to certain conditions, if (i) certain
Net Cash Proceeds are available to the Issuer as a result of an Asset Sale or
(ii) a Change of Control occurs, the Issuer shall be required to make an Offer
to Purchase for all or a specified portion of the Dollar Securities.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securities under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding.  The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Issuer with certain provisions of the Indenture and certain
past defaults under the Indenture and its consequences.  Any such consent or
waiver by the Holder of this Dollar Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Dollar Security and of any
Dollar Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Dollar Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Dollar Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities, the Holders of not less than 25% in principal amount of the
Securities at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities at the
time Outstanding a direction inconsistent with such request and shall have
failed to institute any such proceeding for 60 days after receipt of such
notice, request and offer of indemnity.  The foregoing shall not apply to
certain suits described in the Indenture, including any suit instituted by the
Holder of this Dollar Security for the enforcement of any payment of principal
hereof or any premium or interest hereon on or after the respective due dates
expressed herein (or, in the case of redemption, on or after the Redemption Date
or, in the case of any purchase of this Dollar Security required to be made
pursuant to an Offer to Purchase, on the Purchase Date).

     No reference herein to the Indenture and no provision of this Dollar
Security or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to

                                      -35-
<PAGE>

pay the principal of (and premium, if any) and interest on this Dollar Security
at the times, place and rate, and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Dollar Security is registrable in the Security
Register, upon surrender of this Dollar Security for registration of transfer at
the office or agency of the Issuer in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Dollar Securities, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

     The Dollar Securities are issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof.  As provided in
the Indenture and subject to certain limitations therein set forth, Dollar
Securities are exchangeable for a like aggregate principal amount of Dollar
Securities of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Dollar Security for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this Dollar Security is registered as the owner
hereof for all purposes, whether or not this Dollar Security be overdue, and
neither the Issuer, the Trustee nor any such agent shall be affected by notice
to the contrary.

     Interest on this Dollar Security shall be computed on the basis of a 360-
day year of twelve 30-day months.

     All terms used in this Dollar Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

     In the event of redemption or purchase pursuant to an Offer to Purchase of
this Euro Security in part only, a new Euro Security or Euro Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

     If an Event of Default shall occur and be continuing, there may be declared
due and payable the principal amount of (together with accrued and unpaid
interest on) the Euro Securities, in the manner and with the effect provided in

     [IF EURO SECURITY IS A RESTRICTED SECURITY, THEN INSERT -- The Holder of
this Euro Security (and any Person that has a beneficial interest in this Euro
Security) is entitled to the benefits of an Exchange and Registration Rights
Agreement, dated as of December 1, 1999, and as the same may be amended from
time to time (the "Exchange and Registration Rights Agreement"), executed by the
Issuer.  The Exchange and Registration Rights Agreement provides that Liquidated
Damages will be payable by the Issuer on the Euro Securities for specified
periods if the Issuer does not comply with certain of its obligations
thereunder. Issuer agrees to pay Liquidated Damages, if any, accruing on this
Euro Security.]

     The Indenture provides that, subject to certain conditions, if (i) certain
Net Cash Proceeds are available to the Issuer as a result of an Asset Sale or
(ii) a Change of Control occurs, the Issuer shall be required to make an Offer
to Purchase for all or a specified portion of the Euro Securities.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securities under the Indenture at
any time by the Issuer and the Trustee or Authentication Agent with the consent
of the Holders of a majority in aggregate principal amount of the Securities at
the time Outstanding.  The Indenture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the Securities
at the time Outstanding, on behalf of the Holders of all the Securities, to
waive compliance by the Issuer with certain provisions of the Indenture and
certain past defaults under the Indenture and its consequences.  Any such
consent or waiver by the Holder of this Euro Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Euro Security and
of any Euro Security issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Euro Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Euro Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or
authentication agent or for any other remedy thereunder, unless such Holder
shall have previously given the Trustee or Authentication Agent written notice
of a continuing Event of Default with respect to the Securities, the Holders of
not less than 25% in principal amount of the Securities at the time Outstanding
shall have made written request to the Trustee or Authentication Agent to
institute proceedings in respect of such Event of Default as Trustee or
Authentication Agent and offered the Trustee or Authentication Agent reasonable
indemnity and the Trustee or Authentication Agent shall not have received from
the Holders of a

                                      -42-

majority in principal amount of Securities at the time Outstanding a direction
inconsistent with such request and shall have failed to institute any such
proceeding for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Euro Security for
the enforcement of any payment of principal hereof or any premium or interest
hereon on or after the respective due dates expressed herein (or, in the case of
redemption, on or after the Redemption Date or, in the case of any purchase of
this Euro Security required to be made pursuant to an Offer to Purchase, on the
Purchase Date).

     No reference herein to the Indenture and no provision of this Euro Security
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Euro Security at the times, place and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Euro Security is registrable in the Security
Register, upon surrender of this Euro Security for registration of transfer at
the office or agency of the Issuer in the Borough of Manhattan, The City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Euro Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Euro Securities are issuable only in registered form without coupons in
denominations of Euro 1,000 and any integral multiple thereof.  As provided in
the Indenture and subject to certain limitations therein set forth, Euro
Securities are exchangeable for a like aggregate principal amount of Euro
Securities of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Euro Security for registration of
transfer, the Issuer, the Trustee or Authentication Agent and any agent of the
Issuer or the Trustee or Authentication Agent may treat the Person in whose name
this Euro Security is registered as the owner hereof for all purposes, whether
or not this Euro Security be overdue, and neither the Issuer, the Trustee nor
Authentication Agent nor any such agent shall be affected by notice to the
contrary.

     Interest on this Euro Security shall be computed on the basis of a 360-day
year of twelve 30-day months.

                   ----------------------------------------------
Securities shall be executed on behalf of the Issuer by any two of the Chairman
of the Board, Chief Executive Officer, the President, any Vice President, the
Secretary, any Assistant Secretary, the Chief Financial Officer, the Treasurer
or any Assistant Treasurer. The signature of any of these officers on the
Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of an Issuer shall bind the Issuer,
notwithstanding that such individuals or any of them have ceased to hold such
offices at the time of the authentication and delivery of such Securities or did
not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Issuer may deliver Original Securities executed by the Issuer to
the Trustee or Authentication Agent for authentication, together with an Issuer
Order for the authentication and delivery of such Original Securities; and the
Trustee or Authentication Agent in accordance with the Issuer order shall
authenticate and make available for delivery such Original Securities as
provided in this Indenture and not otherwise.

     At any time and from time to time after the execution and delivery of this
Indenture and on or prior to December 8, 2000, the Issuer may, pursuant to a
Board Resolution, deliver Additional Securities executed by the Issuer to the
Trustee or Authentication Agent for authentication, together with an Issuer
Order for the authentication and delivery of such Additional Securities, an
Officers' Certificate stating that the issuance of such Additional Securities
will not result in a breach or violation of any of the covenants contained in
this Indenture and that all conditions precedent to such issuance,
authentication and delivery of Additional Securities in this Indenture have been
fully complied with and satisfied, and the Trustee or Authentication Agent in
accordance with the Issuer

                                      -47-
<PAGE>

Order shall authenticate and deliver such Securities. Prior to authenticating
such Additional Securities, and accepting any additional responsibilities under
this Indenture in relation to such Securities, the Trustee and any
Authentication Agent shall be entitled to receive, if requested, and (subject to
Section 601) shall be fully protected in relying upon, an Opinion of Counsel
stating in substance that the issuance of such Additional Securities will not
result in a breach or violation of any of the covenants contained in this
Indenture and as to the due authorization, execution and delivery of the
Additional Securities, the enforceability of the Additional Securities, and the
duly incorporated status and good standing of the Issuer. If the Issuer issues
Securities on or after December 8, 1999 (other than Securities issued pursuant
to Section 304, 305, 306, 307, 906 or 1108) the Issuer shall deliver the same
documents as certificates that it is required to deliver in connection with the
issuance of Additional Securities.

     At any time and from time to time after the execution and delivery of this
Indenture and after the effectiveness of a registration statement under the
Securities Act with respect to such Securities, the Issuer may deliver Exchange
Securities executed by the Issuer to the Trustee or Authentication Agent for
authentication, together with an Issuer Order for the authentication and
delivery of such Exchange Securities and a like principal amount of Original
Securities for cancellation in accordance with Section 310 of this Indenture,
and the Trustee or Authentication Agent in accordance with the Issuer Order
shall authenticate and make available for delivery such Securities.  Prior to
authenticating such Exchange Securities, and accepting any additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, if requested, and (subject to Section 601)
shall be fully protected in relying upon, an Opinion of Counsel as to the due
authorization, execution and delivery of the Exchange Securities, the
enforceability of the Exchange Securities, and the duly incorporated status and
good standing of the Issuer.

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee or Authentication Agent by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

     SECTION 304.  Temporary Securities.  Pending the preparation of definitive
                   --------------------
Securities, the Issuer may execute, and upon Issuer Order, the Trustee or
Authentication Agent shall authenticate and deliver, temporary Securities, which
Securities are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution
thereof.

     If temporary Securities are issued, the Issuer will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities

                                      -48-
<PAGE>

shall be exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Issuer designated pursuant to Section
1002, without charge to the Holder. Upon surrender for cancellation (which
cancellation shall be only by the Trustee) of any one or more temporary
Securities, the Issuer shall execute and the Trustee or Authentication Agent
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged, the
temporary Securities shall in all respects be entitled to the same rights and
benefits under this Indenture as definitive Securities.

     SECTION 305.  Global Securities.  (a)  Each Global Security authenticated
                   -----------------
under this Indenture shall be registered in the name of the Depositary
designated by the Issuer for such Global Security or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and
each such Global Security shall constitute a single Security for all purposes of
this Indenture.

     (b)  Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (i) such Depositary (A) has notified the Issuer that it is
unwilling or unable to continue as Depositary for such Global Security or (B) is
principally located in the U.S. and has ceased to be a clearing agency
registered as such under the Exchange Act, and in either case the Issuer fails
to appoint a successor Depositary within 120 days of such notice, (ii) the
Issuer executes and delivers to the Trustee an Issuer Order stating that it
elects to cause the issuance of the Securities in certificated form and that all
Global Securities shall be exchanged in whole for Securities that are not Global
Securities (in which case such exchange shall be effected by the Trustee) or
(iii) there shall have occurred and be continuing an Event of Default with
respect to the Securities.

     (c)  If any Global Security is to be exchanged for other Securities or
cancelled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Trustee, as Security Registrar, for exchange or cancellation
as provided in this Article Three.  If any Global Security is to be exchanged
for other Securities or cancelled in part, or if another Security is to be
exchanged in whole or in part for a beneficial interest in any Global Security,
then either (i) such Global Security shall be so surrendered for exchange or
cancellation as provided in this Article Three or (ii) the principal amount
thereof shall be reduced or increased by an amount equal to the portion thereof
to be so exchanged or cancelled, or equal to the principal amount of such other
Security to be so exchanged for a beneficial interest therein, as the case may
be, by means of an appropriate adjustment made on the records of the Trustee, as
Security Registrar, whereupon the Trustee, in accordance with the Applicable
Procedures, shall instruct the Depositary or its authorized representative to
make a corresponding adjustment to its records.  Upon any such surrender or
adjustment of a Global Security, the Trustee shall, subject to Section 306(b)
and as otherwise provided in this Article Three, authenticate and deliver any
Securities issuable in exchange for such Global Security (or any portion
thereof) to or upon the order of, and registered in such names as may be
directed by, the Depositary or its authorized representative.  Upon the request
of the Trustee in

                                      -49-
<PAGE>

connection with the occurrence of any of the events specified in the preceding
paragraph, the Issuer shall promptly make available to the Trustee a reasonable
supply of Securities that are not in the form of Global Securities. The Trustee
shall be entitled to rely upon any order, direction or request of the Depositary
or its authorized representative which is given or made pursuant to this Article
Three if such order, direction or request is given or made in accordance with
the Applicable Procedures and in accordance with all applicable laws.

     (d) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article Three or otherwise, shall be
authenticated and delivered in the form of, and shall be, a Global Security,
unless such Security is registered in the name of a Person other than the
Depositary for such Global Security or a nominee thereof.

     (e) The Depositary or its nominee, as registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under
this Indenture and the Securities and owners of beneficial interests in a Global
Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members.

     SECTION 306.  Registration, Registration of Transfer and Exchange
                   ---------------------------------------------------
Generally; Restrictions on Transfer and Exchange; Securities Act Legends.
- ------------------------------------------------------------------------

     (a) Registration, Registration of Transfer and Exchange Generally.  The
         -------------------------------------------------------------
Issuer shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Issuer designated pursuant to Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Issuer shall provide for the
registration of Securities and of transfers and exchanges of Securities.  The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers and exchanges of Securities as herein provided.  Such
Security Register shall distinguish between Original Securities, Additional
Securities and Exchange Securities and between Dollar Securities and Euro
Securities.

     Subject to the other provisions of this Indenture regarding restrictions on
transfer, upon surrender for registration of transfer of any Security at an
office or agency of the Issuer designated pursuant to Section 1002 for such
purpose, the Issuer shall execute, and the Trustee or Authentication Agent shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denominations, of a
like currency and aggregate principal amount and bearing such restrictive
legends as may be required by this Indenture.

     At the option of the Holder, and subject to the other provisions of this
Section 306, Securities may be exchanged for other Securities of any authorized
denominations, of a like currency and

                                      -50-
<PAGE>

aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture upon surrender of the Securities to be exchanged at
any such office or agency. Whenever any Securities are so surrendered for
exchange, the Issuer shall execute, and the Trustee or Authentication Agent
shall authenticate and make available for delivery, the Securities which the
Holder making the exchange is entitled to receive.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Issuer, evidencing the same
debt, and (except for the differences between Original Securities and Exchange
Securities provided for herein) entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Issuer or the Security Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Issuer and the Security Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuer may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Sections 304, 305, 306, 906, 1015, 1016 or 1108 not
involving any transfer.

     The Issuer and the Trustee shall not be required (i) to issue, register the
transfer of, or exchange any Security during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 1104 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption, in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

     (b)  Certain Transfers and Exchanges.  Notwithstanding any other provision
          -------------------------------
of this Indenture or the Securities, transfers and exchanges of Securities and
beneficial interests in a Global Security of the kinds specified in this Section
306(b) shall be made only in accordance with this Section 306(b).  Transfers and
exchanges subject to this Section 306(b) shall also be subject to the other
provisions of this Indenture that are not inconsistent with this Section 306(b).

          (1) Restricted Global Security to Regulation S Global Security.  If
              ----------------------------------------------------------
the owner of a beneficial interest in the Restricted Global Security wishes at
any time to transfer such interest to a Person who is required or permitted to
acquire the same in the form of a beneficial interest in the Regulation S Global
Security, such transfer may be effected only in accordance with the provisions
of this clause (b)(1) subject to the Applicable Procedures; provided that no
transfers from a Restricted Global Security to a Regulation S Global Security
shall be permitted during the Distribution Compliance Period. Upon receipt by
the Trustee, as Security Registrar, of (A) an order given by the appropriate
Depositary or its authorized representative directing that a beneficial

                                     -51-
<PAGE>

interest in the appropriate Regulation S Global Security in a specified
principal amount be credited to a specified Agent Member's account and that a
beneficial interest in the Restricted Global Security in an equal principal
amount be debited from another specified Agent Member's account, and (B) a
Regulation S Certificate, satisfactory to the Trustee and duly executed by the
owner of such beneficial interest in the Restricted Global Security or his
attorney duly authorized in writing, then the Trustee, as Security Registrar but
subject to clause (b)(4) below, shall reduce the principal amount of the
appropriate Restricted Global Security and increase the principal amount of the
appropriate Regulation S Global Security by such specified principal amount as
provided in Section 305(c); provided that such transfers shall only occur
between or among Global Dollar Securities or between or among Global Euro
Securities.

          (2)  Regulation S Global Security to Restricted Global Security.  If
               ----------------------------------------------------------
the owner of a beneficial interest in the Regulation S Global Security wishes at
any time to transfer such interest to a Person who is required or permitted to
acquire the same in the form of a beneficial interest in the Restricted Global
Security, such transfer may be effected only in accordance with this clause
(b)(2) and subject to the Applicable Procedures. Upon receipt by the Trustee, as
Security Registrar, of (A) an order given by the Depositary or its authorized
representative directing that a beneficial interest in the Restricted Global
Security in a specified principal amount be credited to a specified Agent
Member's account and that a beneficial interest in the Regulation S Global
Security in an equal principal amount be debited from another specified Agent
Member's account and (B) if such transfer is to occur during the Distribution
Compliance Period, a Restricted Securities Certificate, satisfactory to the
Trustee and duly executed by the owner of such beneficial interest in the
Regulation S Global Security or his attorney duly authorized in writing, then
the Trustee, as Security Registrar, shall reduce the principal amount of the
Regulation S Global Security and increase the principal amount of the Restricted
Global Security by such specified principal amount as provided in Section
305(c); provided that such transfers shall only occur between or among Global
Dollar Securities or between or among Global Euro Securities.

          (3)  Exchanges between Global Security and Non-Global Security.  A
               ---------------------------------------------------------
beneficial interest in a Global Security may be exchanged for a Security that is
not a Global Security as provided in Section 305, provided that, if such
interest is a beneficial interest in a Restricted Global Security, then such
interest shall be exchanged for a Restricted Security (subject in each case to
Section 306(c)).

          (4)  Regulation S Global Dollar Security to be Held Through Euroclear
               ----------------------------------------------------------------
or Cedelbank during Distribution Compliance Period.  The Issuer shall use its
- --------------------------------------------------
best efforts to cause the Depositary for the Regulation S Global Dollar Security
to ensure that beneficial interests in the Regulation S Global Dollar Security
may be held only in or through accounts maintained at the Depositary by
Euroclear or Cedelbank (or by Agent Members acting for the account thereof)
until the expiration of the Distribution Compliance Period, and no person shall
be entitled to effect any transfer or exchange that would result in any such
interest being held otherwise than in or through such an account until the
expiration of the Distribution Compliance Period; provided that this clause

                                     -52-
<PAGE>

(b)(4) shall not prohibit any transfer or exchange of such an interest in
accordance with clause (b)(2) above.

          (5)  Regulation S Global Euro Security to be Held Through Euroclear
               --------------------------------------------------------------
during Distribution Compliance Period.  The Issuer shall use its best efforts to
- -------------------------------------
cause the Depositary to ensure that beneficial interests in the Regulation S
Global Euro Security may be held only in or through accounts maintained by
Euroclear (or by Agent Members acting for the account thereof) until the
expiration of the Distribution Compliance Period, and no person shall be
entitled to effect any transfer or exchange that would result in any such
interest being held otherwise than in or through such an account until the
expiration of the Distribution Compliance Period; provided that this clause
(b)(5) shall not prohibit any transfer or exchange of such an interest in
accordance with clause (b)(2) above.

     (c)  Securities Act Legends.  Rule 144A Securities and their respective
          ----------------------
Successor Securities shall bear a Restricted Securities Legend, and Regulation S
Securities and their Successor Securities shall bear a Regulation S Legend,
subject to the following:

          (1) subject to the following clauses of this Section 306(c), a
Security or any portion thereof which is exchanged, upon transfer or otherwise,
for a Global Security or any portion thereof shall bear the Securities Act
Legend borne by such Global Security while represented thereby;

          (2) subject to the following clauses of this Section 306(c), a new
Security which is not a Global Security and is issued in exchange for another
Security (including a Global Security) or any portion thereof, upon transfer or
otherwise, shall bear the Securities Act Legend borne by such other Security,
provided that, if such new Security is required pursuant to Section 306(b)(3) to
be issued in the form of a Restricted Security, it shall bear a Restricted
Securities Legend and, if such new Security is so required to be issued in the
form of a Regulation S Security, it shall bear a Regulation S Legend;

          (3) Registered Securities shall not bear a Securities Act Legend;

          (4) at any time after the Securities may be freely transferred without
registration under the Securities Act or without being subject to transfer
restrictions pursuant to the Securities Act, a new Security which does not bear
a Securities Act Legend may be issued in exchange for or in lieu of a Security
(other than a Global Security) or any portion thereof which bears such a legend
if the Trustee has received an Unrestricted Securities Certificate, satisfactory
to the Trustee and duly executed by the Holder of such legended Security or his
attorney duly authorized in writing, and after such date and receipt of such
certificate, the Trustee or Authentication Agent shall authenticate and make
available for delivery such a new Security in exchange for or in lieu of such
other Security as provided in this Article Three;

                                      -53-
<PAGE>

          (5) a new Security which does not bear a Securities Act Legend may be
issued in exchange for or in lieu of a Security (other than a Global Security)
or any portion thereof which bears such a legend if, in the Issuer's judgment,
placing such a legend upon such new Security is not necessary to ensure
compliance with the registration requirements of the Securities Act, and the
Trustee or Authentication Agent, at the direction of the Issuer, shall
authenticate and deliver such a new Security as provided in this Article Three
provided that, the Trustee, if it deems reasonably necessary or appropriate, may
request an Opinion of Counsel in connection with such direction; and

     Notwithstanding the foregoing provisions of this Section 306(c), a
Successor Security of a Security that does not bear a particular form of
Securities Act Legend shall not bear such form of legend unless the Issuer has
reasonable cause to believe that such Successor Security is a "restricted
security" within the meaning of Rule 144, in which case the Trustee or
Authentication Agent, at the direction of the Issuer, shall authenticate and
make available for delivery a new Security bearing a Restricted Securities
Legend in exchange for such Successor Security as provided in this Article
Three.

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

     The Trustee and the Authentication Agent shall have no 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 Security (including any transfers between or
among Depositary participants or beneficial owners of interests in any Global
Security) 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 307.  Mutilated, Destroyed, Lost and Stolen Securities.  If any
                   ------------------------------------------------
mutilated Security is surrendered to the Trustee, the Issuer shall execute and
the Trustee or Authentication Agent shall authenticate and make available for
delivery in exchange therefor a new Security of like tenor, currency and
principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Issuer and the Trustee (i) evidence to
its satisfaction of the destruction, loss or theft of any Security and (ii) such
security or indemnity as may be required by either of them to save each of them
and any agent of either of them completely harmless, then, in the absence of
notice to the Issuer or the Trustee that such Security has been acquired by a
bona fide purchaser, the Issuer shall execute and upon its written request the
Trustee or Authentication Agent shall authenticate and make available for
delivery, in lieu of any such destroyed, lost or stolen Security, a new Security
of like tenor, currency and principal amount and bearing a number not
contemporaneously outstanding.

                                      -54-
<PAGE>

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Issuer in its discretion may, instead
of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Issuer and
the Trustee (without duplication) may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee
and reasonable attorneys' fees) connected therewith.

     Every new Security issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Issuer, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     SECTION 308.  Payment of Interest; Interest Rights Preserved.  Interest on
                   ----------------------------------------------
any Security which is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

     Any interest on any Security which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder on such date, and such
Defaulted Interest may be paid by the Issuer, at its election in each case, as
provided in clause (1) or (2) below:

     (1) The Issuer may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or its respective Predecessor Securities)
are registered at the close of business on a Special Record Date for the payment
of such Defaulted Interest, which shall be fixed in the following manner: The
Issuer shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Issuer shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Issuer of such Special Record
Date and, in

                                      -55-
<PAGE>

the name and at the sole expense of the Issuer, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor
to be mailed, first-class postage prepaid, to each Holder at his address as it
appears in the Security Register, not less than 10 days prior to such Special
Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest
shall be paid to the Persons in whose names the Securities (or its respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2).

     (2) The Issuer may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after written notice given by the Issuer to the Trustee of
the proposed payment pursuant to this clause, such manner of payment shall be
deemed practicable by the Trustee in its reasonable judgment.

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

     SECTION 309.  Persons Deemed Owners.  Prior to due presentment of a
                   ---------------------
Security for registration of transfer, the Issuer, the Trustee and any agent of
the Issuer or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 308) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Issuer, the Trustee nor any agent of the Issuer or the
Trustee shall be affected by notice to the contrary.

     None of the Issuer, the Trustee or any agent of the Issuer or the Trustee
shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.  Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Issuer or the Trustee, or any agent of the Issuer or the Trustee,
from giving effect to any written certification, proxy or other authorization
furnished by any Depositary (or its nominee), as a Holder, with respect to such
Security in global form or impair, as between such Depositary and owners of
beneficial interests in such Security in global form, the operation of customary
practices governing the exercise of the rights of such Depositary (or its
nominee) as a Holder of such Security in global form.

     SECTION 310.  Cancellation.  All Securities surrendered for payment,
                   ------------
redemption, registration of transfer or exchange or pursuant to any Offer to
Purchase pursuant to Section 1015 or 1016 shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee and shall be promptly

Authentication Agent, as the case may be, for cancellation any Securities
previously authenticated and delivered hereunder which the Issuer may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of as directed by an Issuer order, provided, that
in no event shall the Trustee be required to destroy such canceled Securities.

     SECTION 311.  CUSIP, ISN Numbers.  The Issuer in issuing the Securities may
                   ------------------
use "CUSIP" of "ISN" numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP" or "ISN" numbers in notices 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 Securities or as contained
in any notice and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Issuer will promptly notify
the Trustee of any change in the "CUSIP" or "ISN" numbers.

     SECTION 312.  Computation of Interest.  Interest on the Securities shall be
                   -----------------------
computed on the basis of a 360-day year of twelve 30-day months.

     SECTION 401.  Satisfaction and Discharge of Indenture.  This Indenture
                   ---------------------------------------

for), and the Trustee, on written demand of and at the sole expense of the
Issuer, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture (including, but not limited to, Article Twelve
hereof), when

     (1)  either

replaced or paid as provided in Section 307 and (ii) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Issuer and thereafter repaid to the Issuer or discharged from such

Authentication Agent, as the case may be, for cancellation; or

          (B) all such Securities not theretofore delivered to the Trustee for
cancellation

              (i)  have become due and payable, or

               (iii) are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the sole expense, of the Issuer,

and the Issuer, in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
the purpose an amount in cash or U.S. Government Securities sufficient to pay
and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal (and premium, if any)
and interest to the date of such deposit (in the case of Securities which have
become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be including, without limitation, the payment of all fees and expenses
of the Trustee, its agents and counsel;

an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have

or through any Paying Agent (including the Issuer acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal (and premium, if any) and interest for whose payment such money has
been deposited with the Trustee.

     SECTION 502.  Acceleration of Maturity; Rescission and Annulment.  If an
                   --------------------------------------------------
Event of Default (other than an Event of Default specified in Section 501(8) or
(9)) occurs and is continuing, then and in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
may declare the Securities to be due and payable immediately, by a notice in
writing to the Issuer (and to the Trustee if given by Holders), and upon any
such declaration the principal and any accrued interest on all Outstanding
Securities shall become immediately due and payable.  If an Event of Default
specified in Section 501(8) or (9) occurs, the principal of and any accrued
interest on the Securities then Outstanding shall ipso facto become immediately
due and payable without any declaration or other Act on the part of the Trustee
or any Holder.

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Issuer and the Trustee, may rescind and annul such declaration and its
consequences if

     (1) the Issuer has paid or deposited with the Trustee a sum sufficient to
pay

         (A) the principal of (and premium, if any, on) any Securities which
have become due otherwise than by such declaration of acceleration (including
any Securities required to have been purchased on the Purchase Date pursuant to
an Offer to Purchase made by the Issuer) and, to

                                      -60-
<PAGE>

the extent that payment of such interest is lawful, any interest thereon at the
rate provided therefor in the Securities,

          (B) to the extent that payment of such interest is lawful, interest
upon overdue interest at the rate provided therefor in the Securities, and

          (C) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

     (2)  all Events of Default, other than the non-payment of the principal of
(and premium, if any) or interest on, the Securities which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     SECTION 503.  Collection of Indebtedness and Suits for Enforcement by
                   -------------------------------------------------------
Trustee.  The Issuer covenants that if
- -------

     (1)  default is made in the payment of any interest on any Security when
such interest becomes due and payable and such default continues for a period of
30 days, or

     (2)  default is made in the payment of the principal of (or premium, if
any, on) any Security at the Maturity thereof or, with respect to any Security
required to have been purchased pursuant to an Offer to Purchase made by the
Issuer, at the Purchase Date thereof, the Issuer will, upon demand of the
Trustee, pay to it, for the benefit of the Holders of such Securities, the whole
amount then due and payable on such Securities for principal (and premium, if
any) and interest, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest, at the rate provided therefor in the Securities, and,
in addition thereto, 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 and
any amounts due the Trustee under Section 607 hereof.

     If the Issuer fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Issuer or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Issuer or any other obligor upon the Securities, wherever
situated.

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the

                                      -61-
<PAGE>

specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

     SECTION 504.  Trustee May File Proofs of Claim.  In case of any judicial
                   --------------------------------
proceeding relative to the Issuer or any other obligor upon the Securities, or
its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding.  In particular, the Trustee
shall be authorized to collect, receive and distribute any moneys or other
property payable or deliverable on any such claims and to distribute the same;
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official 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 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 607.

     No provision of this Indenture 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 Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

     SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.
                   -----------------------------------------------------------
All rights of action and claims under this Indenture or the Securities may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any amounts due the Trustee
under Section 607 hereof, be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

     SECTION 506.  Application of Money Collected.  Subject to Article Thirteen,
                   ------------------------------
any money collected by the Trustee pursuant to this Article shall be applied in
the following order, at the date or dates fixed by the Trustee and, in case of
the distribution of such money on account of principal (or premium, if any) or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

     FIRST:  To the payment of all amounts (including, without limitation, the
reasonable compensation, expenses, disbursements and advances due the Trustee,
its agents and counsel and any other amounts) due the Trustee under Section 607;
and

     SECOND:  To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Securities due the Holders in respect
of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind,

                                      -62-
<PAGE>

according to the amounts due and payable on such Securities for principal (and
premium, if any) and interest, respectively.

     SECTION 507.  Limitation on Suits.  No Holder of any Security shall have
                   -------------------
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless

     (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default;

     (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute
proceedings or pursue remedies in respect of such Event of Default in its own
name as Trustee hereunder;

     (3) such Holder or Holders have offered and provided to the Trustee
reasonable indemnity satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred in compliance with such request;

     (4) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding or pursued any
remedies; and

     (5) no direction which is inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

     SECTION 508.  Unconditional Right of Holders to Receive Principal, Premium
                   ------------------------------------------------------------
and Interest.  Notwithstanding any other provision in this Indenture, the Holder
- ------------
of any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date or in the case of an Offer to Purchase made by the Issuer and required to
be accepted as to such Security, on the Purchase Date) and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired or
affected without the consent of such Holder.

     SECTION 509.  Restoration of Rights and Remedies.  If the Trustee or any
                   ----------------------------------
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee

                                      -63-
<PAGE>

or to such Holder, then and in every such case, subject to any determination in
such proceeding, the Issuer, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

     SECTION 510.  Rights and Remedies Cumulative.  Except as otherwise provided
                   ------------------------------
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities in the last paragraph of Section 307, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

     SECTION 511.  Delay or Omission Not Waiver.  No delay or omission of the
                   ----------------------------
Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

     SECTION 512.  Control by Holders.  The Holders of a majority in principal
                   ------------------
amount of the Outstanding Securities shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee, provided that

     (1)  the Trustee may refuse to follow any direction which

          (i)  conflicts with any rule of law or with this Indenture,

               or

          (ii) the Trustee, in its reasonable judgment, determines may be unduly
prejudicial to the rights of other Holders of Securities, or may expose the
Trustee to personal liability, or does not provide adequate indemnification
against any loss or expense resulting from the compliance therewith, and

     (2)  the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

     SECTION 513.  Waiver of Past Defaults.  The Holders of not less than a
                   -----------------------
majority in principal amount of the Outstanding Securities may on behalf of the
Holders of all the Securities, by written notice to the Trustee, waive any past
default hereunder and its consequences, except a default

                                      -64-
<PAGE>

     (1) in the payment of the principal of (or premium, if any) or interest on
any Security (including any Security which is required to have been purchased
pursuant to an Offer to Purchase which has been made by the Issuer), or

     (2) in respect of a covenant or provision hereof which under Article Nine
cannot be modified or amended without the consent of the Holder of each
Outstanding Security affected.

     Upon any such waiver, such default shall be cured and 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 514.  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, suffered or omitted by it as Trustee, a court may require any
party litigant in such suit to file an undertaking to pay the reasonable costs
of such suit, and may assess reasonable costs against any such party litigant,
in the manner and to the extent provided in the Trust Indenture Act; provided,
that this Section shall not be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Trustee
and provided, further that, subject to a court's discretion, this Section shall
not apply to a suit by the Trustee, and as provided in the Trust Indenture Act.

     SECTION 515.  Waiver of Stay, or Extension Laws.  The Issuer covenants (to
                   ---------------------------------
the extent that they may lawfully do so) that they will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Issuer (to the extent that they may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that
they will not hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.


                                  ARTICLE SIX

                                  The Trustee

     SECTION 601.  Certain Duties and Responsibilities.
                   -----------------------------------

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his own affairs.

                                      -65-
<PAGE>

     (b)  Except during the continuance of an Event of Default:

          (1) the duties of the Trustee shall be determined solely by the
express provisions of this Indenture and the Trustee need perform only those
duties that are specifically set forth in this Indenture and no others, and no
implied covenants or obligations shall be read into this Indenture against the
Trustee, and

          (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, the
Trustee shall examine the certificates and opinions to determine whether or not
they conform to the requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated
therein).

     (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
that:

          (1) this paragraph does not limit the effect of paragraph (b) of this
Section;

          (2) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts;

          (3) the Trustee shall not be liable with respect to any action it
takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 512 hereof; and

          (4) no provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     (d)  Whether or not therein expressly so provided, every provision of this

however, that in the case of any default specified in Section 501(5), no such
notice to Holders shall be given until at least 30 days after the occurrence of
such default

                                      -66-

(without regard to any Notice of Default). For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

     Except in the case of an Event of Default in payment of principal of
(premium, if any) or interest on any Security, the Trustee may withhold 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.

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

                                      -67-
<PAGE>

     (g) the Trustee may execute any of the trusts or powers hereunder or

notice references the Securities or this Indenture.

     SECTION 604.  Not Responsible for Recitals or Issuance of Securities.  The
                   ------------------------------------------------------
recitals contained herein and in the Securities, except the certificates of
authentication, shall be taken as the statements of the Issuer, and the Trustee
assumes no responsibility for its correctness.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities.  The Trustee shall not be accountable for the use or application by
the Issuer of Securities or the proceeds thereof.

     SECTION 605.  May Hold Securities; Act as Trustee under Other Indentures.
                   ----------------------------------------------------------
The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar
or any other agent of the Issuer, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 608 and 613,
may otherwise deal with the Issuer and any other obligor upon the Securities
with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent.

     The Trustee is hereby authorized to act as trustee under that certain
indenture between the Issuer and the Trustee, dated as of July 1, 1998 (the
"1998 Senior Indenture"), that certain Indenture dated as of March 1, 1999 (the
"Old Subordinated Indenture"), and that certain Indenture dated as of the date
hereof relating to Convertible Subordinated Notes due July 15, 20008 (the "New
Subordinated Indenture" and collectively with the 1998 Senior Indenture and the
Old Subordinated Indenture, the "Prior Indentures") notwithstanding any
provisions of this Indenture or the Prior Indentures affecting the relative
rights of holders of securities issued under such indentures to payment thereon
and to security given to secure such payment. The Trustee may become and act as
trustee under other indentures under which other securities, or certificates of
interest or participation in other securities, of the Company are outstanding in
the same manner as if it were not Trustee hereunder. The Trustee is authorized
to resign from any of its appointments as Trustee hereunder, as trustee under
any of the Prior Indentures, or as trustee under any other indenture in the
event that the Trustee determines in good faith that its performance hereunder
or thereunder subjects the Trustee to a conflict of interest.

     SECTION 606.  Money Held in Trust.  Money held by the Trustee in trust
                   -------------------
hereunder need not be segregated from other funds except to the extent required
by law.  The Trustee shall be under

                                      -68-
<PAGE>

no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Issuer.

     SECTION 607.  Compensation and Reimbursement.  The Issuer agrees
                   ------------------------------

     (1) to pay to the Trustee from time to time such reasonable compensation
for all services rendered by it hereunder as may be agreed in writing from time
to time (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the compensation, expenses
and disbursements of its agents, accountants, experts and counsel), except any
such expense, disbursement or advance as may be attributable to its negligence
or bad faith; and

     (3) to indemnify the Trustee and any predecessor Trustee and their agents
for, and to hold them harmless against, any loss, damage, claims, liability or
expense (including, without limitation, reasonable attorneys' fees and expenses
and taxes (other than taxes based upon, measured by or determined by the income
of such Person) incurred without negligence or bad faith on its part, arising
out of or in connection with the acceptance or administration of this trust,
including the costs and expenses of defending itself against any claim or
liability (not arising from negligence or bad faith) in connection with the
exercise or performance of any of its powers or duties hereunder.

     The Trustee shall notify the Issuer promptly upon acquiring knowledge of
any claim for which it is entitled to be indemnified hereunder.  Failure by the
Trustee to so notify the Issuer shall not relieve the Issuer of its obligations
hereunder unless the Issuer are prejudiced thereby.  If the Issuer elect to
defend the claim, the Issuer shall be entitled to control the defense of such
claim and the Trustee shall cooperate in such defense.  The Trustee may have
separate counsel, and the Issuer shall pay the reasonable fees and expenses of
such counsel until such time as the Issuer assumes the defense of such claim,
and thereafter, to the extent that in the Trustee's reasonable judgment its
interests conflict with or differ from those of the Issuer under such claim.
The Issuer need not pay for any settlement made without its consent, which
consent shall not be unreasonably withheld.

     The Trustee shall have a lien prior to the Securities as to all property
and funds held by it hereunder for any amount owing it or any predecessor
Trustee pursuant to this Section 607, except with respect to funds held in trust
for the benefit of the Holders of particular Securities.

     The obligations of the Issuer under this Section 607 shall survive the
resignation or removal of the Trustee and/or satisfaction and discharge of this
Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 501(9) or (10) hereof occurs, the expenses and the
compensation for the services (including

                                      -69-
<PAGE>

the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any applicable bankruptcy law.

     SECTION 608.  Disqualification; Conflicting Interests.  If the Trustee has
                   ---------------------------------------
or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest within 90 days,
apply to the Commission for permission to continue, or resign, to the extent and
in the manner provided by, and subject to the provisions of, the Trust Indenture
Act and this Indenture.

Corporate Trust Office or agency in The Borough of Manhattan, City of New York.
If such Person or bank holding company publishes reports of condition at least

examining authority, then for the purposes of this Section, the combined capital
and surplus of such Person or bank holding company shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published.  If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

of a Security for at least six months, or

<PAGE>

shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then, in any such
case, (i) the Issuer by Board Resolutions of the Issuer may remove the Trustee,
or (ii) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Issuer,
by Board Resolution of the Issuer, shall promptly appoint a successor Trustee.
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Issuer and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Issuer.
If, within 30 days after the retiring Trustee resigns, no successor Trustee
shall have been so appointed by the Issuer or the Holders of a majority in
principal amount of the Outstanding Securities and accepted appointment in the
manner hereinafter provided, the retiring Trustee or any Holder who has been a
bona fide Holder of a Security for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor Trustee.

     (f) The Issuer shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 106. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

     SECTION 611.  Acceptance of Appointment by Successor.  Every successor
                   --------------------------------------
Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuer
and to the retiring Trustee a written instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Issuer or the successor Trustee,
such retiring Trustee shall, upon payment of all sums owing to the retiring
Trustee hereunder and subject to the Lien provided for in Section 607 hereof,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.  Upon request of any such successor Trustee,
the Issuer shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.  Notwithstanding the replacement of the Trustee pursuant to this Section
611, the Issuer's obligations under Section 607 hereof shall continue for the
benefit of the retiring Trustee.

     SECTION 612.  Merger, Conversion, Consolidation or Succession to Business.
                   -----------------------------------------------------------
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee, or any corporation
into which all or substantially all of its corporate trust business is
transferred, may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

     SECTION 613.  Preferential Collection of Claims Against Issuer.  If and
                   ------------------------------------------------
when the Trustee shall be or become a creditor of the Issuer (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Issuer(or
any such other obligor).

     SECTION 614.  Appointment of Authenticating Agent.  The Trustee may appoint
                   -----------------------------------
an Authenticating Agent or Agents which shall be authorized to act on behalf of
the Trustee to authenticate Securities issued upon original issue and upon
exchange, registration of transfer, partial conversion or partial redemption or
pursuant to Section 307, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
reasonably acceptable to the Issuer.  If such Authenticating Agent or bank
holding company publishes reports of condition at least annually, pursuant to
law or to the requirements of said supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
Authenticating Agent or bank holding company shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

     The Trustee hereby appoints the Euro Agent as Authentication Agent for
purposes of authenticating any Euro Securities.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an

                                      -72-
<PAGE>

Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Issuer.  The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Issuer.  Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be reasonably acceptable to the Issuer and shall mail written
notice of such appointment by first-class mail, postage prepaid, to all Holders
as its names and addresses appear in the Security Register.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments from the Issuer, subject to
the provisions of Section 607.

     If an appointment is made pursuant to this Section, the Securities may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

     This is one of the Securities described in the within-mentioned Indenture.

relieved of all obligations and covenants under this Indenture and the
Securities.

the consent of any Holders, the Issuer, when authorized by a Board Resolution,
and the Trustee, at any time and from time to time, may enter into one or more
indentures supplemental hereto, in form satisfactory to the Trustee, for any of

     SECTION 902.  Supplemental Indentures with Consent of Holders.  With the
                   -----------------------------------------------
consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities, by Act of said Holders delivered to the Issuer and the
Trustee, the Issuer, when authorized by Board Resolutions of the Issuer, and the
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any

<PAGE>

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

     SECTION 903.  Execution of Supplemental Indentures.  In executing, or
                   ------------------------------------
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by
this Indenture. The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

     SECTION 904.  Effect of Supplemental Indentures.  Upon the execution of any
                   ---------------------------------
supplemental indenture under this Article, this Indenture shall be modified in

Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

     SECTION 905.  Conformity with Trust Indenture Act.  Every supplemental
                   -----------------------------------

                   --------------------------------------------------
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Issuer shall so determine, new Securities so
modified as to conform, in the opinion of the Trustee and the Issuer, to any
such supplemental indenture may be prepared and executed by the Issuer and

for Outstanding Securities.


                                  ARTICLE TEN

                                   Covenants

     SECTION 1001. Payment of Principal, Premium and Interest.  The Issuer will
                   ------------------------------------------
duly and punctually pay the principal of (and premium, if any) and interest on
the Securities in accordance with the terms of the Securities and this
Indenture.

     SECTION 1002. Maintenance of Office or Agency.  The Issuer will maintain
                   -------------------------------
in the Borough of Manhattan, The City of New York, an office or agency where
Securities may be presented or surrendered for payment, where Securities may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Issuer in respect of the Securities and this Indenture
may be served. The Issuer will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Issuer shall fail to

                                      -78-
<PAGE>

maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the
Issuer hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Issuer may also from time to time designate one or more other offices
or agencies (in or outside the Borough of Manhattan, The City of New York) where
the Securities may be presented or surrendered for any or 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 Issuer of its
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such purposes.  The Issuer will 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.

     SECTION 1003. Money for Security Payments to Be Held in Trust.  If the
                   -----------------------------------------------
Issuer shall at any time act as its own Paying Agent, it will, on or before each
due date of the principal of (and premium, if any) or interest on any of the
Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
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 Issuer shall have one or more Paying Agents, it will, on or
before each due date of the principal of (and premium, if any) or interest on
any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
as provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Issuer will promptly notify the Trustee of its action or failure so
to act.

     The Issuer 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 (i) comply with the provisions of the Trust Indenture Act applicable
to it as a Paying Agent (or, until such time as this Indenture shall be
qualified under the Trust Indenture Act, which would be applicable to it as
Paying Agent if this Indenture were so qualified) and (ii) in the event and
during the continuance of any default by the Issuer (or any other obligor upon
the Securities) in the making of any payment in respect of the Securities, upon
the written request of the Trustee, forthwith pay to the Trustee all sums held
in trust by such Paying Agent as such.

     The Issuer may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Issuer
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Issuer 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 Issuer 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.

                                      -79-
<PAGE>

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuer, in trust for the payment of the principal of (and premium, if any)
or interest on any Security 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 Issuer on Issuer request, or (if then held by the Issuer) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Issuer for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuer 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 Issuer cause to be
published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New
York and Luxembourg, 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 publication, any unclaimed balance of such money then remaining will be
repaid to the Issuer.

     SECTION 1004.  Existence.  Subject to Article Eight and Section 1015, the
                    ---------
Issuer will do or cause to be done all things necessary to preserve and keep in
full force and effect its existence, rights (charter and statutory) and
franchises; provided, however, that Issuer shall not be required to preserve any
such right or franchise if the Issuer in good faith shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Issuer and that the loss thereof is not disadvantageous in any material
respect to the Holders.

     SECTION 1005.  Maintenance of Properties.  The Issuer will cause all
                    -------------------------
material properties used or useful in the conduct of its business or the
business of any Restricted Subsidiary of the Issuer to be maintained and kept in
good condition, repair and working order (reasonable wear and tear excepted) and
supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Issuer may be necessary so that the business carried on in
connection therewith may be properly conducted at all times; provided, however,
that nothing in this Section shall prevent an Issuer or any of its Restricted
Subsidiaries from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, as determined by the Issuer or Restricted
Subsidiary in good faith, desirable in (or not adverse to) the conduct of its
business or the business of any Restricted Subsidiary and not adverse in any
material respect to the Holders.

     SECTION 1006.  Payment of Taxes and Other Claims.  The Issuer will pay or
                    ---------------------------------
discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all material taxes, assessments and governmental charges levied
or imposed upon the Issuer or any of its Restricted Subsidiaries or upon the
income, profits or property of the Issuer or any of its Restricted Subsidiaries,
and (2) all material lawful claims for labor, materials and supplies which, if
unpaid, might by law become a lien upon the property of the Issuer or any of its
Restricted Subsidiaries; provided, however, that the Issuer shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate negotiations or proceedings.

                                      -80-
<PAGE>

     SECTION 1007.  Maintenance of Insurance.  The Issuer shall, and the Issuer
                    ------------------------
shall cause its Restricted Subsidiaries to, keep at all times all of its
properties which are of an insurable nature insured (which may include self-
insurance) against loss or damage with insurers believed by the Issuer to be
responsible to the extent that property of similar character is usually so
insured by corporations similarly situated and owning like properties in
accordance with good business practice.

     SECTION 1008.  Limitation on Debt.  The Issuer will not, and will not
                    ------------------
permit any of its Restricted Subsidiaries to, Incur any Debt; provided that the
Issuer may Incur Debt if, after giving effect to the incurrence of such Debt and
the receipt and application of the proceeds therefrom, the Consolidated Debt to
EBITDA Ratio would be greater than zero and less than 6:1.

     Notwithstanding the foregoing limitation, the following Debt may be
Incurred, each item to be given independent effect:

          (1)  Permitted Senior Bank Debt;

          (2)  Debt owed (A) to the Issuer evidenced by a promissory note, or
(B) to any Restricted Subsidiary; provided that any event which results in any
such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
subsequent transfer of such Debt (other than to the Issuer or another Restricted
Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such
Debt not permitted by this clause (2);

          (3)  Debt of the Issuer or any Restricted Subsidiary (A) in respect of
performance, surety or appeal bonds or letters of credit in the ordinary course
of business, (B) under Permitted Interest Rate or Currency Protection
Agreements, or (C) arising under, or arising from, agreements providing for
indemnification, adjustment of purchase price or similar obligations, or from
Guarantees or letters of credit, surety bonds or performance bonds securing any
obligations of the Issuer Incurred in connection with the disposition of any
business, assets (other than Guarantees of Debt Incurred by any Person acquiring
all or any portion of such business, assets or Restricted Subsidiary for the
purpose of financing such acquisition), in a principal amount not to exceed the
gross proceeds actually received by the Issuer or any Restricted Subsidiary in
connection with such disposition;

          (4)  Debt which is exchanged for or the proceeds of which are used to
refinance or refund, or any extension or renewal of (each a "refinancing"), (a)
the Securities, (b) Debt incurred pursuant to clauses (3), (5), (6), (8) and (9)
of this paragraph and this clause (4), in each case in an aggregate principal
amount not to exceed the principal amount of the Debt so refinanced (together
with any accrued interest and any premium and other payment required to be made
with respect to the Debt being refinanced or refunded, and any fees, costs,
expenses, underwriting discounts or commissions and other payments paid or
payable with respect to the Debt incurred pursuant to this clause (4));
provided, however, that (A) Debt, the proceeds of which are used to refinance
the Securities, or Debt which is pari passu with or subordinate in right of
payment to the Securities, shall only be permitted if (x) in the case of any
refinancing of the Securities or Debt which is pari passu to

                                      -81-
<PAGE>

the Securities, the refinancing Debt is Incurred by the Issuer and made pari
passu to the Securities or subordinated to the Securities, and (y) in the case
of any refinancing of Debt which is subordinated to the Securities, the
refinancing Debt is Incurred by the Issuer and is subordinated to the Securities
in a manner that is at least as favorable to the Holders as that of the Debt
refinanced; (B) the refinancing Debt by its terms, or by the terms of any
agreement or instrument pursuant to which such Debt is issued, does not have a
final maturity prior to the final maturity of the Debt being refinanced and has
an Average Life longer than the Average Life of the Debt being refinanced; and
(C) in the case of any refinancing of Debt Incurred by the Issuer, the
refinancing of Debt may be Incurred only by the Issuer, and in the case of any
refinancing of Debt Incurred by a Restricted Subsidiary, the refinancing Debt
may be Incurred only by such Restricted Subsidiary or the Issuer;

          (5)  Acquisition Debt of the Issuer or any Restricted Subsidiary;

          (6)  Exchange Securities and Additional Securities;

          (7)  Debt of the Issuer not to exceed, at any time outstanding, two
times the Net Cash Proceeds received by the Issuer after the Closing Date from
the issuance and sale of its Capital Stock (other than Disqualified Stock) to a
Person that is not a Subsidiary of the Issuer, to the extent that such Net Cash
Proceeds have not been used pursuant to clause (C)(3) of the first paragraph or
clauses (iii), (iv) or (vii) of the second paragraph of Section 1011 to make a
Restricted Payment; provided that such Debt does not have a final maturity prior
to the final maturity of the Securities and has an Average Life longer than the
Average Life of the Securities;

          (8)  Existing Debt of the Issuer;

          (9)  Debt of the Issuer or any Restricted Subsidiary Incurred to
finance the purchase or other acquisition of any property, inventory, asset or
business directly or indirectly, by the Issuer or any Restricted Subsidiary used
in, or to be used in, the System and Network Management Business;

          (10) Subordinated Debt of the Issuer not to exceed $300.0 million in
principal outstanding at any time; provided that the calculation of the
principal amount of such Subordinated Debt shall exclude the principal amount of
the New Convertible Notes; and

          (11) other Debt of the Issuer or any Restricted Subsidiary not to
exceed $50.0 million at any one time outstanding.

     For purposes of determining compliance with this Section 1008, in the event
that an item of Debt meets the criteria of more than one of the types of Debt
described in the above clauses, or is permitted in part under the first
paragraph of this Section 1008 and in part under one or more of the above
clauses, the Issuer, in its sole discretion, shall classify, and from time to
time may reclassify, such item of Debt.

                                      -82-
<PAGE>

     For purposes of determining any particular amount of Debt under Section
1008, Guarantees, Liens or obligations with respect to letters of credit
supporting Debt otherwise included in the determination of such particular
amount shall not be included.

     SECTION 1009. Limitation on Sale-Leaseback Transactions.  The Issuer will
                   -----------------------------------------
not, and will not permit any Restricted Subsidiary to, enter into any sale-
leaseback transaction involving any of its assets or properties, whether now
owned or hereafter acquired, whereby the Issuer or a Restricted Subsidiary sells
or transfers such assets or properties and then or thereafter leases such assets
or properties or any part thereof or any other assets or properties that the
Issuer or such Restricted Subsidiary, as the case may be, intends to use for
substantially the same purpose or purposes as the assets or properties sold or
transferred.

     The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess of
three years; (ii) the sale-leaseback transaction is consummated within 180 days
after the purchase of the assets subject to such transaction; (iii) the
transaction is solely between the Issuer and any Wholly Owned Restricted
Subsidiary or solely between Wholly Owned Restricted Subsidiaries; or (iv) the
Issuer or such Restricted Subsidiary, within 12 months after the sale or
transfer of any assets or properties is completed, applies an amount no less
than the Net Cash Proceeds received from such sale in accordance with clause (A)
or (B) of the second paragraph of Section 1015(1).

     SECTION 1010. Limitation on Guarantees of Issuer Debt by Restricted
                   -----------------------------------------------------
Subsidiaries. The Issuer may not permit any Restricted Subsidiary, directly or
- ------------
indirectly, to Guarantee, assume or in any other manner become liable for the
payment of any Debt of the Issuer (other than Debt of the Issuer Incurred
pursuant to clauses (1), (3), (5), (9) or (11) of the second paragraph of
Section 1008 or refinanced pursuant to clause (4) of the second paragraph of
Section 1008 of Debt originally incurred under clause (3), (5) or (9) of the
second paragraph of Section 1008) that is pari passu with or subordinate in
right of payment to the Securities unless: (i) (A) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture providing for a
Guarantee of payment of the Securities by such Restricted Subsidiary; and (B)
with respect to any Guarantee of Debt of the Issuer that is subordinate in right
of payment to the Securities, such Guarantee shall be subordinated to such
Restricted Subsidiary's Guarantee with respect to the Securities at least to the
same extent as such Debt is subordinated to the Securities, and (ii) such
Restricted Subsidiary waives, and will not in any manner whatsoever claim or
take the benefit or advantage of, any rights of reimbursement, indemnity or
subrogation or any other rights against the Issuer or any other Restricted
Subsidiary as a result of any payment by such Restricted Subsidiary under its
Guarantee until the Securities have been paid in full.

     Notwithstanding the foregoing, any Guarantee by a Restricted Subsidiary may
provide by its terms that it shall be automatically and unconditionally released
and discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Issuer, of all of the Issuers and each Restricted Subsidiary's
Capital Stock in, or all or substantially all of the assets of, such Restricted
Subsidiary (which sale, exchange or transfer is not prohibited by this
Indenture) or (ii) the release or

                                      -83-
<PAGE>

discharge of the Guarantee which resulted in the creation of such Restricted
Subsidiary's Guarantee with respect to the Securities, except a discharge or
release by or as a result of payment under such Guarantee.

     SECTION 1011.  Limitation on Restricted Payments.  The Issuer will not, and
                    ---------------------------------
will not permit any Restricted Subsidiary directly or indirectly to:

          (1) declare or pay any dividend or make any distribution on or with
respect to its Capital Stock to Persons other than the Issuer or any of its
Restricted Subsidiaries, (other than (x) dividends or distributions payable
solely in shares of its Capital Stock (other than Disqualified Stock), or in
options, warrants or other rights to acquire shares of such Capital Stock; (y)
pro rata dividends or distributions on Common Stock of Restricted Subsidiaries
held by minority stockholders; or (z) dividends in respect of Disqualified
Stock);

          (2) purchase, redeem, retire or otherwise acquire for value any shares
of Capital Stock of (A) the Issuer or an Unrestricted Subsidiary (including
options, warrants or other rights to acquire such shares of Capital Stock) held
by any Person, or (B) a Restricted Subsidiary (including options, warrants or
other rights to acquire such shares of Capital Stock) held by any Person other
than the Issuer or a Wholly Owned Restricted Subsidiary of the Issuer;

          (3) make any voluntary or optional principal payment, or voluntary or
optional redemption, repurchase, defeasance, or other acquisition or retirement
for value, of Debt of the Issuer that is subordinated in right of payment to the
Securities; or

          (4) make any Investment, other than a Permitted Investment, in any
Person,

(such payments or any other actions described in clauses (1) through (4) above
being collectively "Restricted Payments") if, at the time of, and after giving
effect to, the proposed Restricted Payment:

              (A) a Default or Event of Default shall have occurred and be
continuing;

              (B) the Issuer could not Incur at least $1.00 of Debt under the
first paragraph of Section 1008; or

              (C) the aggregate amount of all Restricted Payments (the amount,
if other than in cash, to be determined in good faith by the Board of Directors,
whose determination shall be conclusive and evidenced by a Board Resolution)
made after the Closing Date shall exceed the sum of: (1) cumulative Consolidated
EBITDA since the date of original issuance of the Securities through the last
day of the last full fiscal quarter ending immediately preceding the date of
such Restricted Payment for which quarterly or annual financial statements are
available; minus (2) 1.5 times cumulative Consolidated Interest Expense of the
Issuer since the date of original issuance of the Securities through the last
day of the last full fiscal quarter ending immediately preceding the date of
such Restricted Payment for which quarterly or annual financial statements are
available, plus (3) the

                                      -84-
<PAGE>

aggregate Net Cash Proceeds received by the Issuer after the Closing Date from
the issuance and sale permitted by this Indenture of its Capital Stock (other
than Disqualified Stock) to a Person who is not a Subsidiary of the Issuer,
including an issuance or sale permitted by this Indenture of Debt of the Issuer
for cash subsequent to the Closing Date upon the conversion of such Debt into
Capital Stock (other than Disqualified Stock) of the Issuer, or from the
issuance to a Person who is not a Subsidiary of the Issuer of any options,
warrants or other rights to acquire Capital Stock of the Issuer (in each case,
exclusive of any Disqualified Stock or any options, warrants or other rights
that are redeemable at the option of the holder, or are required to be redeemed,
prior to the stated final maturity date of the Securities), in each case except
to the extent such Net Cash Proceeds are used to Incur Debt pursuant to clause
(vii) of the second paragraph of Section 1008, plus (4) an amount equal to the
net reduction in Investments (other than reductions in Permitted Investments) in
any Person resulting from payments of interest on Debt, dividends, repayments of
loans or advances, or other transfers of assets, in each case to the Issuer or
any Restricted Subsidiary or from the Net Cash Proceeds from the sale of any
such Investment (except, in each case, to the extent any such payment or
proceeds are included in the calculation of Consolidated EBITDA), or from
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to
exceed, in each case, the amount of Investments previously made by the Issuer or
any Restricted Subsidiary in such Person or Unrestricted Subsidiary.

The foregoing provision shall not be violated by reason of:

          (i)   the payment of any dividend within 60 days after the date of

     SECTION 1012. Limitation on Dividend and Other Payment Restrictions
                   -----------------------------------------------------
Affecting Restricted Subsidiaries. The Issuer may not, and may not permit any
- ---------------------------------
Restricted Subsidiary 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 (i) to pay dividends (in cash or otherwise)
or make any other distributions in respect of its Capital Stock owned by the
Issuer or any other Restricted Subsidiary or pay any Debt or other obligation
owed to the Issuer or any other Restricted Subsidiary; (ii) to make loans or
advances to the Issuer or any other Restricted Subsidiary; or (iii) to transfer
any of its property or assets to the Issuer or any other Restricted Subsidiary.
Notwithstanding the foregoing, the Issuer may, and may permit any Restricted
Subsidiary to, suffer to exist any such encumbrance or restriction:

     (1) pursuant to any agreement in effect on the date of original issuance of
the Securities, and any amendments, extensions, refinancings, renewals or
replacements of such agreements, provided that the amendments, encumbrances and
restrictions in any such extensions, refinancings, renewals or replacements are
no less favorable in any material respect to the Holders, than those
encumbrances or restrictions that are then in effect and that are being
extended, refinanced, renewed or replaced;

     (2) existing under or by reason of applicable law;

     (3) existing in connection with any Permitted Senior Bank Debt or any Debt
incurred pursuant to clause (5) of the second paragraph of Section 1008;

     (4) pursuant to an agreement existing prior to the date on which such
Person became a Restricted Subsidiary and not Incurred in anticipation of
becoming a Restricted Subsidiary, which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than
the Person so acquired;

     (5) pursuant to an agreement entered into in connection with Debt Incurred
under clause (4) of the second paragraph of Section 1008; provided, however,
that the provisions contained in such agreement related to such encumbrance or
restriction are no more restrictive in any material respect than the provisions
contained in the agreement the subject of the refinancing such clause (4) of the
second paragraph of Section 1008;

     (6) restrictions contained in any agreement relating to a Lien of a
Restricted Subsidiary or the Issuer otherwise permitted under this Indenture,
but only to the extent such restrictions restrict the transfer of the property
subject to such Lien;

                                      -87-
<PAGE>

     (7)  customary nonassignment provisions entered into in the ordinary course
of business in leases, licenses and other contracts to the extent such

of any such lease or the assignment of rights under any such contract;

     (8)  any restriction with respect to a Restricted Subsidiary imposed
pursuant to an agreement which has been entered into for the sale or disposition
of all or substantially all of the Capital Stock or assets of such Restricted
Subsidiary; provided that consummation of such transaction would not result in
an Event of Default or an event that, with the passing of time or the giving of
notice or both, would constitute an Event of Default, that such restriction
terminates if such transaction is closed or abandoned and that the closing or
abandonment of such transaction occurs within one year of the date such
agreement was entered into;

     (9)  any restriction imposed pursuant to contracts for the sale of assets
with respect to the transfer of the assets to be sold pursuant to such contract;

     (10) arising or agreed to in the ordinary course of business, not relating
to any Debt, and that do not, individually, or in the aggregate, detract from
the value of property or assets of the Issuer or any Restricted Subsidiary in
any manner material to the Issuer or any Restricted Subsidiary; or

     (11) such encumbrance or restriction is contained in the terms of any
agreement pursuant to which such Debt was issued if (A) the encumbrance or
restriction applies only in the event of a payment default or a default with
respect to a financial covenant contained in such Debt or agreement, (B) the
encumbrance or restriction is not materially more disadvantageous to the Holders
of the Securities than is customary in comparable financings, and (C) the Issuer
determines that any such encumbrance or restriction will not materially affect
the Issuer's ability to make principal or interest payments on the Securities.

     SECTION 1013.  Limitation on Liens. The Issuer may not, and may not permit
                    -------------------
any Restricted Subsidiary to, Incur or suffer to exist any Lien, on or with
respect to any property or assets now owned or hereafter acquired to secure any
Debt without making, or causing such Restricted Subsidiary to make, effective
provision for securing the Securities (x) equally and ratably with such Debt as
to such property or assets for so long as such Debt will be so secured or (y) in
the event such Debt is Debt of the Issuer which is subordinate in right of
payment to the Securities, prior to such Debt as to such property or assets for
so long as such Debt will be so secured.

     The foregoing restrictions shall not apply to:

          (1)  Liens in existence on the date of original issuance of the
Securities;

          (2)  Liens securing only the Securities and any Lien in favor of the
Trustee for the benefit of Holders arising under the provisions in this
Indenture;

acquisition thereof (and not Incurred in anticipation of the financing of such
acquisition);

          (7) Liens on property of a Person existing at the time such Person
becomes a Restricted Subsidiary and not incurred in anticipation of becoming a
Restricted Subsidiary;

          (8) any interest in or title of a lessor to any property subject to a
Capital Lease Obligation which is permitted under this Indenture; or

          (9) Liens to secure Debt Incurred pursuant to clause (4) of the
second paragraph of Section 1008; provided that such Lien does not extend to any
property other than the property securing the Debt being refinanced pursuant to
clause (4) of the second paragraph of Section 1008.

     SECTION 1014.  Limitation on Issuance of Capital Stock of Restricted
                    -----------------------------------------------------
Subsidiaries.  The Issuer will not sell, and will not permit any Restricted
- ------------
Subsidiary, directly or indirectly, to issue or sell, any shares of Capital
Stock of a Restricted Subsidiary (including options, warrants or other rights to
purchase shares of such Capital Stock) except (i) to the Issuer or a Wholly
Owned Restricted Subsidiary; (ii) issuances of director's qualifying shares or
sales to foreign nationals of shares of Capital Stock of foreign Restricted
Subsidiaries, to the extent required by applicable law; (iii) if, immediately
after giving effect to such issuance or sale, such Restricted Subsidiary would
no longer constitute a Restricted Subsidiary and any Investment in such Person
remaining after giving effect to such issuance or sale would have been permitted
under Section 1011 if made on the date of such issuance or sale; or (iv)
issuances or sales of Common Stock of a Restricted Subsidiary.

     SECTION 1015.  Asset Sales.
                    -----------

     (1)  The Issuer will not, and will not permit any Restricted Subsidiary to,
consummate an Asset Sale unless (i) the Issuer or the applicable Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale at least equal to the fair market value of the assets sold or otherwise
disposed of (as evidenced by a resolution of the Board of Directors), and (ii)
at least 75% of the consideration received by the Issuer or the Restricted
Subsidiary, as the case may be, from such Asset Sale shall be cash or other
Qualified Consideration.

     The Issuer or any Restricted Subsidiary may, within 365 days of the Asset
Sale, invest the Net Cash Proceeds thereof (A) in property or assets used, or to
be used, in the System and Network Management Business, or in a company engaged
primarily in the System and Network Management

                                      -89-
<PAGE>

Business (if and to the extent otherwise permitted under this Indenture), or (B)
to repay Secured Debt of the Issuer or any Restricted Subsidiary. The amount of
such Net Cash Proceeds not used or invested within 365 days of the Asset Sale in
the manner described in clauses (A) and (B) above shall constitute "Excess
Proceeds."

     In the event that Excess Proceeds exceed $10.0 million, the Issuer shall
make an Offer to Purchase that amount of Securities equal to the amount of
Excess Proceeds at a price equal to 100% of the principal amount of the
Securities to be purchased, plus accrued and unpaid interest and Liquidated
Damages thereon, if any, to the date of purchase and, to the extent required by
the terms thereof, any other Debt of the Issuer that is pari passu with the
Securities or Debt of a Restricted Subsidiary.  Each Offer to Purchase shall be
mailed within 30 days following the date that the Issuer shall become obligated
to purchase Securities with any Excess Proceeds.  Following the completion of an
Offer to Purchase, the amount of Excess Proceeds shall be deemed to be reset at
zero and, to the extent there are any remaining Excess Proceeds the Issuer may
use such Excess Proceeds for any use which is not otherwise prohibited by this
Indenture.

     The Issuer will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the purchase
of Securities pursuant to such Offer to Purchase.

     (2) Not later than the date of the Offer with respect to an Offer to
Purchase pursuant to this Section 1015, the Issuer shall deliver to the Trustee
an Officers' Certificate as to (i) the Purchase Amount, (ii) the allocation of
the Net Cash Proceeds from the Asset Sale(s) pursuant to which such Offer is
being made, including, if amounts are invested in assets related to the business
of the Issuers, the actual assets acquired and a statement indicating the
relationship of such assets to the business of the Issuer and (iii) the
compliance of such allocation with the provisions of Section 1015(1).

     The Issuer shall perform its obligations specified in the Offer for the
Offer to Purchase.  On or prior to the Purchase Date, the Issuer shall (i)
accept for payment (on a pro rata basis, if necessary) Securities or portions
thereof tendered pursuant to the Offer, (ii) deposit with the paying agent (or,
if the Issuer is acting as its own paying agent, segregate and hold in trust as
provided in Section 1003) money sufficient to pay the purchase price of all
Securities or portions thereof so accepted and (iii) deliver or cause to be
delivered to the Trustee all Securities so accepted together with an Officers'
Certificate stating the Securities or portions thereof accepted for payment by
the Issuers.  The Paying Agent (or the Issuers, if so acting) shall promptly
mail or deliver to Holders of Securities so accepted payment in an amount equal
to the purchase price, and the Trustee or Authentication Agent shall promptly
authenticate and mail or deliver to such Holders a new Security equal in
principal amount to any unpurchased portion of the Security surrendered.  Any
Security not accepted for payment shall be promptly mailed or delivered by the
Issuer to the Holder thereof.  The Issuer shall publicly announce the results of
the Offer on or as soon as practicable after the Purchase Date.

     SECTION 1016.  Change of Control.
                    -----------------

                                      -90-
<PAGE>

     (1) If a Change of Control shall occur at any time, then each Holder of
Securities shall have the right to require that the Issuer purchase such
Holder's Securities, in whole or in part in integral multiples of $1,000 or Euro
1,000, as the case may be, at a purchase price in cash, in an amount equal to
101% of the principal amount of such Securities or portion thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, to the date of purchase,
pursuant to the Offer to Purchase and in accordance with the other procedures
set forth in this Indenture.  Within 30 days following the Change of Control,
the Issuer will mail an Offer to Purchase to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to purchase Securities on the date specified in the Offer to Purchase.  The
Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable in connection with the purchase of the Securities
pursuant to the Offer to Purchase.

     (2) The Issuer shall perform its obligations specified in the Offer to
Purchase and the Trustee shall perform its obligations arising hereunder in
connection therewith.  Prior to the Purchase Date, the Issuer shall (i) accept
for payment Securities or portions thereof tendered pursuant to the Offer, (ii)
deposit with the Paying Agent (or, if the Issuer is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) money sufficient
to pay the purchase price of all Securities or portions thereof so accepted and
(iii) deliver or cause to be delivered to the Trustee all Securities so accepted
together with an Officers' Certificate stating the Securities or portions
thereof accepted for payment by the Issuer.  The Paying Agent shall promptly
mail or deliver to Holders of Securities so accepted payment in an amount equal
to the purchase price, and the Trustee or Authentication Agent shall promptly
authenticate and mail or deliver to such Holders a new Security or Securities
equal in principal amount to any unpurchased portion of the Security surrendered
as requested by the Holder.  Any Security not accepted for payment shall be
promptly mailed or delivered by the Issuer to the Holder thereof.  The Issuer
shall publicly announce the results of the Offer on or as soon as practicable
after the Purchase Date.

     (3) Notwithstanding the foregoing, the Issuer will not be required to make
an Offer to Purchase upon a Change of Control if a third party makes the Offer
to Purchase in the manner, at the times and otherwise in compliance with the
requirements set forth in this Section 1016 and this Indenture applicable to the
Offer to Purchase made by the Issuer and purchases all Securities validly
tendered and not withdrawn under such Offer to Purchase.

     SECTION 1017.  Transactions with Affiliates and Related Persons.  The
                    ------------------------------------------------
Issuer may not, and may not permit any Restricted Subsidiary to, enter into any
transaction (or series of related transactions) not in the ordinary course of
business with an Affiliate or Related Person of the Issuer (other than the
Issuer or a Wholly Owned Restricted Subsidiary) involving aggregate
consideration in excess of $5.0 million, including any Investment, either
directly or indirectly, unless such transaction is on terms no less favorable to
the Issuer or such Restricted Subsidiary than those that could be obtained in a
comparable arm's-length transaction with an entity that is not an Affiliate or
Related Person and is in the best interests of the Issuer or such Restricted
Subsidiary.  For any

                                      -91-
<PAGE>

transaction (or series of related transactions) that involves less than or equal
to $10.0 million, the Chief Executive Officer, President or Chief Operating
Officer of the Issuer shall determine that the transaction satisfies the above
criteria and shall evidence such a determination by an Officer's Certificate
filed with the Trustee. For any transaction that involves in excess of $10.0
million, (a) a majority of the disinterested members of the Board of Directors
shall determine that the transaction satisfies the above criteria or (b) the
Issuer shall obtain a written opinion of a nationally recognized investment
banking or appraisal firm stating that the transaction is fair to the Issuer or
such Restricted Subsidiary.

     The foregoing limitation does not apply, and shall not apply, to (i) any
transaction solely between the Issuer and any Restricted Subsidiary or solely
between any Restricted Subsidiaries; (ii) the payment of reasonable and
customary regular fees to directors of the Issuer who are not employees of the
Issuer; (iii) any payments or other transactions pursuant to any tax-sharing
agreement between the Issuer and any other Person with which the Issuer files a
consolidated tax return or with which the Issuer is part of a consolidated group
for tax purposes; (iv) licensing or sublicensing or the use of any intellectual
property by the Issuer or any Restricted Subsidiary to the Issuer or any
Restricted Subsidiary; (v) any transaction entered into for the purpose of
granting or altering registration rights with respect to any Capital Stock of
the Issuer; (vi) any Restricted Payments not prohibited by Section 1011 or (vii)
compensation, severance and employee benefit arrangements with any officer,
director or employee of the Issuer or any Restricted Subsidiary, including under
any stock option or stock incentive plans, in the ordinary course of business.

     SECTION 1018.  Unrestricted Subsidiaries.  The Issuer may designate any
                    -------------------------
Subsidiary of the Issuer to be an "Unrestricted Subsidiary" as provided below in
which event such Subsidiary and each other Person that is then, or thereafter
becomes, a Subsidiary of such Subsidiary will be deemed to be an Unrestricted
Subsidiary.  "Unrestricted Subsidiary" means (1) any Subsidiary designated as
such by the Board of Directors as set forth below where (a) no default with
respect to any Debt of such Subsidiary or any Subsidiary of such Subsidiary
(including any right which the holders thereof may have to take enforcement
action against such Subsidiary) would permit (upon notice, lapse of time or
both) any holder of any other Debt in a principal amount in excess of $10.0
million of the Issuer and its Subsidiaries (other than another Unrestricted
Subsidiary) to declare a default on such other Debt or cause the payment thereof
to be accelerated or payable prior to its final scheduled maturity and (b) the
Issuer could make a Restricted Payment in an amount equal to the greater of the
fair market value and book value of such Subsidiary pursuant to Section 1011 and
such amount is thereafter treated as a Restricted Payment for the purpose of
calculating the aggregate amount available for Restricted Payments thereunder
and (2) any Subsidiary of an Unrestricted Subsidiary.  The Board of Directors
may not designate a Subsidiary to be an Unrestricted Subsidiary if such
Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property
of, any other Subsidiary of the Issuer which is not a Subsidiary of the
Subsidiary to be so designated or otherwise an Unrestricted Subsidiary.  The
Board of Directors may designate any Unrestricted Subsidiary a Restricted
Subsidiary and shall be deemed to have made such designation if at such time the
condition set forth in clause (a) in the definition of "Unrestricted Subsidiary"
shall cease to be true.

                                      -92-

Issuer shall file with the Commission the annual reports, quarterly reports and
other documents which the Issuer would have been required to file with the
Commission pursuant to such Section 13(a) or 15(d) or any successor provision
thereto if the Issuer were so required, such documents to be filed with the
Commission on or prior to the respective dates (each a "Required Filing Date,"
collectively, the "Required Filing Dates") by which the Issuer would have been
required so to file such documents if the Issuer were so required.  The Issuer
shall also in any event (a) within 15 days of each Required Filing Date (i)
transmit by mail to all Holders, as their names and addresses appear in the
Security Register, without cost to such Holders, and (ii) file with the Trustee,
copies of the annual reports, quarterly reports and other documents which the
Issuer files with the Commission pursuant to such Section 13(a) or 15(d) or any
successor provision thereto or would have been required to file with the
Commission pursuant to such Section 13(a) or 15(d) or any successor provisions
thereto if the Issuer were required to be subject to such Sections and (b) if
filing such documents by the Issuer with the Commission is not permitted under
the Exchange Act, promptly upon written request supply copies of such documents
to any prospective Holder.

     SECTION 1020. Statement by Officers as to Default; Compliance Certificates.
                   ------------------------------------------------------------

     (1) The Issuer will deliver to the Trustee, within 90 days after the end of
its fiscal year, which initially shall be December 31, and within 60 days after
the end of each fiscal quarter (other than the fourth fiscal quarter), of the
Issuer ending after the date hereof an Officers' Certificate, stating whether or
not to the best knowledge of the signers thereof the Issuer is in default in the
performance and observance of any of the terms, provisions and conditions of
Section 801 or Sections 1004 to 1018, inclusive, and if an Issuer shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge.

     (2) The Issuer shall deliver to the Trustee, as soon as possible and in any
event within 10 days after an Issuer becomes aware of the occurrence of an Event
of Default or an event which, with notice or the lapse of time or both, would
constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or default, and the action which the Issuer
proposes to take with respect thereto.

     (3) The Issuer shall deliver to the Trustee within 90 days after the end of
each fiscal year a written statement by the Issuer's independent public
accountants stating (A) that their audit examination has included a review of
the terms of this Indenture and the Securities as they relate to accounting
matters, and (B) whether, in connection with their audit examination, any event
which, with notice or the lapse of time or both, would constitute an Event of
Default under Section 1008 and Section 1011 has come to their attention and, if
such a default has come to their attention, specifying the nature and period of
the existence thereof.

     SECTION 1021.  Waiver of Certain Covenants.  The Issuer may omit in any
                    ---------------------------
particular instance to comply with any covenant or condition set forth in
Section 801 and Sections 1004 to

                                      -93-
<PAGE>

1018, if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Issuer and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect; provided, however, with respect to an Offer to Purchase as to
which an Offer has been mailed, no such waiver may be made or shall be effective
against any Holder tendering Securities pursuant to such Offer, and the Issuer
may not omit to comply with the terms of such Offer as to such Holder.


                                ARTICLE ELEVEN

     (b) The Securities further may be redeemed at the election of the Issuer,
as a whole or from time to time in part, at any time on or after December 15,
2004, at the Redemption Prices specified in the form of Security hereinbefore
set forth together with accrued interest to the Redemption Date.

     SECTION 1102.  Applicability of Article.  Redemption of Securities at the
                    ------------------------
election of the Issuer, as permitted by any provision of this Indenture, shall
be made in accordance with such provision and this Article.

     SECTION 1103.  Election to Redeem; Notice to Trustee.  The election of the
                    -------------------------------------
Issuer to redeem any Securities pursuant to Section 1101 shall be evidenced by a
Board Resolution of the Issuer.  In case of any redemption at the election of
the Issuer of the Securities, the Issuer shall, at least 40 days prior to the
Redemption Date fixed by the Issuer (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date and of the

                                      -94-
<PAGE>

principal amount of Securities to be redeemed (except that in the case of a
redemption pursuant to Section 1101(a), notice shall be given by the Issuer to
the Trustee not less than 15 days prior to the Redemption Date). In the case of
any redemption pursuant to Section 1101(a), the Issuer shall also furnish the
Trustee an Officers' Certificate stating that the Issuer is entitled to effect
such redemption and setting forth a statement of facts showing that the
condition or conditions precedent to the right of the Issuer to redeem have
occurred or been satisfied.

     SECTION 1104.  Selection by Trustee of Securities to Be Redeemed.  If less
                    -------------------------------------------------
than all the Securities are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities not previously called for
redemption, by such method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions (equal to $1,000
or Euro 1,000, as the case may be, or any integral multiple thereof) of the
principal amount of Securities of a denomination larger than $1,000 or Euro
1,000, as the case may be.

     The Trustee shall promptly notify the Issuer and each Security Registrar in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

     SECTION 1105.  Notice of Redemption.  Notice of redemption shall be given
                    --------------------
by first-class mail, postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date by the Issuer, or at its request by the
Trustee (except that in the case of a redemption pursuant to Section 1101(a),
the Issuer shall give notice and such notice shall be given not less than 15 nor
more than 60 days prior to the Redemption Date), to each Holder of Securities to
be redeemed, (with a copy to the Trustee, delivered or mailed to the Corporate
Trust Office) at his address appearing in the Security Register.  The Issuer
shall also issue a Press Release simultaneously with issuing such notice of
redemption and including all of the relevant information from such notice.

     All notices of redemption shall include the CUSIP number (or ISIN number as
applicable) and shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

          (3) whether the redemption is being made pursuant to Section 1101(a)
or (b) and, if being made pursuant to Section 1101(a), a brief statement setting
forth the Issuer's right to effect such redemption and the Issuer's basis
therefor,

                                      -95-
<PAGE>

          (4) if less than all the Outstanding Securities are to be redeemed,
the identification (and, in the case of partial redemption, the principal
amounts) of the particular Securities to be redeemed,

          (5) that on the Redemption Date the Redemption Price will become due
and payable upon each such Security to be redeemed and that interest thereon
will cease to accrue on and after said date, and

          (6) the place or places where such Securities are to be surrendered
for payment of the Redemption Price.

     Notice of redemption of Securities to be redeemed at the election of the
Issuer shall be given by the Issuer or, at the Issuer's request, by the Trustee
in the name and at the sole expense of the Issuer.

     SECTION 1106.  Deposit of Redemption Price.  On or prior to any Redemption
                    ---------------------------
Date, the Issuer shall deposit with the Trustee or with a Paying Agent (or, if
the Issuer is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

     SECTION 1107.  Securities Payable on Redemption Date.  Notice of redemption
                    -------------------------------------
having been given as aforesaid, the Securities so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein
specified, and from and any after such date (unless the Issuer shall default in
the payment of the Redemption Price and any accrued interest) such Securities
shall cease to bear interest.  Upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Issuer at the Redemption Price, together with any applicable accrued interest to
the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to its
terms and the provisions of Section 308.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate provided by the Security.

     SECTION 1108.  Securities Redeemed in Part.  Any Security which is to be
                    ---------------------------
redeemed only in part shall be surrendered at an office or agency of the Issuer
designated for that purpose pursuant to Section 1002 (with, if the Issuer or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Issuer and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Issuer shall
execute, and the Trustee or Authentication Agent shall authenticate and deliver
to the Holder of such Security without service

                                      -96-

charge, a new Security or Securities, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

                      Defeasance and Covenant Defeasance

     SECTION 1201.  Issuer's Option to Effect Defeasance or Covenant Defeasance.
                    -----------------------------------------------------------
The Issuer may at its option by Board Resolution, at any time, elect to have
either Section 1202 or Section 1203 applied to the Outstanding Securities upon
compliance with the conditions set forth below in this Article Twelve.

     SECTION 1202.  Defeasance and Discharge.  Upon the Issuer's exercise of the
                    ------------------------
option provided in Section 1201 applicable to this Section, the Issuer shall be
deemed to have been discharged from its obligations with respect to the
Outstanding Securities on the date the conditions set forth below are satisfied
(hereinafter, "defeasance").  For this purpose, such defeasance means that the
Issuer shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Issuer, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder:  (A) the rights of
Holders of such Securities to receive, solely from the trust fund described in
Section 1204 and as more fully set forth in such Section, payments in respect of
the principal of (and premium, if any) and interest on such Securities when such
payments are due, (B) the Issuer's obligations with respect to such Securities
under Sections 304, 305, 306, 1002 and 1003, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Twelve.
Subject to compliance with this Article Twelve, the Issuer may exercise its
option under this Section 1202 notwithstanding the prior exercise of its option
under Section 1203.

     SECTION 1203.  Covenant Defeasance.  Upon the Issuer's exercise of the
                    -------------------
option provided in Section 1201 applicable to this Section, (i) the Issuer shall
be released from its obligations under Sections 1005 through 1018, inclusive,
and Clauses (3), (4) and (5) of Section 801 and (ii) the occurrence of an event
specified in Sections 501(3), 501(4) (with respect to Clauses (3), (4) or (5) of
Section 801), 501(5) (with respect to any of Sections 1005 through 1018,
inclusive), 501(6) and 501(7) shall not be deemed to be an Event of Default on
and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"). For this purpose, such covenant defeasance means that
the Issuer may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such Section or Clause, whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or Clause or by reason of any reference in any such Section or Clause to
any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

                                      -97-
<PAGE>

     SECTION 1204.  Conditions to Defeasance or Covenant Defeasance.  The
                    -----------------------------------------------
following shall be the conditions to application of either Section 1202 or
Section 1203 to the then Outstanding Securities:

     (1) The Issuer shall irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 609
who shall agree to comply with the provisions of this Article Twelve applicable
to it) as trust funds in trust for the purpose of making the following payments,
specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of such Securities, (A) money in an amount, or (B) U.S. Government
Obligations which through the scheduled payment of principal and interest in
respect thereof in accordance with their terms will provide, not later than one
day before the due date of any payment, money in an amount, or (C) a combination
thereof, sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee (or other qualifying trustee) to pay and discharge, the principal
of, premium, if any, and each instalment of interest on the Securities on the
Stated Maturity of such principal or instalment of interest in accordance with
the terms of this Indenture and of such Securities. For this purpose, "U.S.
Government Obligations" means securities that are (x) direct obligations of the
United States of America for the payment of which its full faith and credit is
pledged or (y) obligations of a Person controlled or supervised by and acting as
an agency or instrumentality of the United States of America the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States of America, which, in either case, are not callable or redeemable
at the option of the issuer thereof, and shall also include a depository receipt
issued by a bank (as defined in Section 3(a)(2) of the Securities Act as
custodian with respect to any such U.S. Government Obligation or a specific
payment of principal of or interest on any such U.S. Government Obligation held
by such custodian for the account of the holder of such depository receipt,
provided that (except as required by law) such custodian is not authorized to
make any deduction from the amount payable to the holder of such depository
receipt from any amount received by the custodian in respect of the U.S.
Government Obligation or the specific payment of principal of or interest on the
U.S. Government Obligation evidenced by such depository receipt.

     (2) In the case of an election under Section 1202, the Issuer shall have
delivered to the Trustee an Opinion of Counsel stating that (x) the Issuer has
received from, or there has been published by, the Internal Revenue Service a
ruling, or (y) since the date of this Indenture there has been a change in the
applicable Federal income tax law, in either case to the effect that, and based
thereon such opinion shall confirm that, the Holders of the Outstanding
Securities will not recognize gain or loss for Federal income tax purposes as a
result of such deposit, defeasance and discharge and will be subject to Federal
income tax on the same amount, in the same manner and at the same times as would
have been the case if such deposit, defeasance and discharge had not occurred.

     (3) In the case of an election under Section 1203, the Issuer shall have
delivered to the Trustee an Opinion of Counsel to the effect that the Holders of
the Outstanding Securities will not recognize gain or loss for Federal income
tax purposes as a result of such deposit and covenant

                                      -98-
<PAGE>

defeasance and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would have been the case if such deposit
and covenant defeasance had not occurred.

     (4) The Issuer shall have delivered to the Trustee an Officer's Certificate
to the effect that the Securities, if then listed on any securities exchange,
will not be delisted as a result of such deposit.

     (5) Such defeasance or covenant defeasance shall not cause the Trustee to
have a conflicting interest as defined in Section 608 and for purposes of the
Trust Indenture Act with respect to any securities of the Issuer.

     (6) No Event of Default or event which with notice or lapse of time or both
would become an Event of Default shall have occurred and be continuing on the
date of such deposit or, insofar as subsections 501(9) and (10) are concerned,
at any time during the period ending on the 121st day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied
until the expiration of such period).

     (7) Such defeasance or covenant defeasance shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Issuer or any Restricted Subsidiaries is a party or by which it is
bound.

     (8) The Issuer shall have delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent provided
for relating to either the defeasance under Section 1202 or the covenant
defeasance under Section 1203 (as the case may be) have been complied with.

     (9) Such defeasance or covenant defeasance shall not result in the trust
arising from such deposit constituting an investment company as defined in the
Investment Issuer Act of 1940, as amended, or such trust shall be qualified
under such act or exempt from regulation thereunder.

     SECTION 1205.  Deposited Money and U.S. Government Obligations to Be Held
                    ----------------------------------------------------------
in Trust; Other Miscellaneous Provisions.  Subject to the provisions of the last
- ----------------------------------------
paragraph of Section 1003, all money and U.S. Government Obligations (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee--
collectively, for purposes of this Section 1205, the "Trustee") pursuant to
Section 1204 in respect of the Securities shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Issuer acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

                                      -99-
<PAGE>

     The Issuer shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1204 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 Securities.

     Anything in this Article Twelve to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuer from time to time upon Issuer Request
any money or U.S. Government Obligations held by it as provided in Section 1204
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent defeasance or covenant defeasance.

     SECTION 1206.  Reinstatement.  If the Trustee or the Paying Agent is unable
                    -------------
to apply any money in accordance with Section 1202 or 1203 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the Issuer's obligations under
this Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Twelve until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 1202 or 1203; provided, however, that if the Issuer makes any payment of
principal of (and premium, if any) or interest on any Security following the
reinstatement of its obligations, the Issuer shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or the Paying Agent.

Registration Rights Agreement dated December 1, 1999 among the Company and

will constitute valid and binding obligations of the Company.

   We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us, if any, in the
Registration Statement, the Prospectus constituting a part thereof and any
amendments thereto.

   This opinion speaks only as of its date and we assume no obligation to
update this opinion should circumstances change after the date hereof. This
opinion is intended solely for the purpose of the above exchange of the New
Notes for Old Notes and is not to be relied upon for any other purpose.

       Euro 125,000,000 aggregate principal amount of
       10 3/4% Senior Notes due 2009

   Ladies and Gentlemen:

   Exodus Communications, Inc., a Delaware corporation (the "Company"), is to
file with the Securities and Exchange Commission (the "Commission") a
registration statement on Form S-4 (the "Registration Statement") under the
Securities Act of 1933 (the "Securities Act") in connection with the Company's
offer to exchange (the "Exchange Offer") up to $375,000,000 aggregate principal
amount of its 10 3/4% Senior Notes due 2009 and Euro 125,000,000 aggregate
principal amount of its 10 3/4% Senior Notes due 2009 (collectively, the "New
Notes") for equal aggregate principal amounts of its outstanding US dollar- and
Euro-denominated 10 3/4% Senior Notes due 2009 (the "Old Notes"). The Old Notes
have been, and the New Notes will be, issued pursuant to a Trust Indenture
dated as of December 1, 1999 (the "Indenture") between the Company and The
Chase Manhattan Bank and Trust Company, National Association, as trustee (the
"Trustee").

   In giving this opinion, we have reviewed copies of the Indenture, the Old
Notes, the form of the New Notes contained in the Indenture, the Exchange and
Registration Rights Agreement dated December 1, 1999 among the Company and
Goldman, Sachs & Co., Donaldson, Lufkin & Jenrette Securities Corporation,
BancBoston Robertson Stephens Inc., PaineWebber Incorporated and Morgan Stanley
& Co. Incorporated and such other documents and have made such other inquiries
and investigations of law as we have deemed necessary or appropriate as a basis
for the opinion hereinafter expressed. In such review, we have assumed the
genuineness of all signatures, the conformity to the original documents of all
documents submitted to us as certified or photostatic copies, the authenticity
of all such documents and all documents submitted to us as original documents
and the lack of any undisclosed termination, modification, waiver or amendment
to any document reviewed by us.

   We are members of the bar of the State of New York, and do not express any
opinion herein as to matters governed by any law other than the law of the
State of New York and the General Corporation Law of the State of Delaware.

   Based upon the foregoing and the assumption that the New Notes have been
duly authorized by the Company and subject to the qualifications set forth
herein, we are of the opinion that when the New Notes are duly executed and
delivered by the Company and authenticated by the Trustee in accordance with
the provisions of the Indenture and delivered in exchange for the Old Notes in
accordance with the Exchange Offer as described in the Registration Statement,
which shall have been declared effective by the Commission, the New Notes will
constitute valid and binding obligations of the Company, except as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance or other laws affecting creditors' rights generally, by general
principles of equity (regardless of whether considered in a proceeding at law
or in equity), including, without limitation, the availability or
unavailability of equitable remedies, and by requirements of reasonableness,
good faith and fair dealing.

   This opinion is delivered to you solely for your use in connection with the
Registration Statement and may not be used or relied upon by you for any other
purpose or by any other person without our prior written consent.

   We consent to the filing of this opinion as an exhibit to the Registration

   As representative of the
   Several Purchasers Named
   on Schedule I hereto

Ladies and Gentlemen:

     Exodus Communications, Inc., a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Purchasers named in Schedule I hereto (the "Purchasers") an aggregate of
$375,000,000 principal amount of 10 3/4% Senior Notes due 2009 (the "Dollar
Securities") and $125,000,000 principal amount of 10 3/4% Senior Notes due 2009
(the "Euro Securities" and together with the Dollar Securities, the
"Securities").

     1.   The Company represents and warrants to, and agrees with, the
Purchasers that:

          (a)  A preliminary offering circular, dated November 24, 1999 (the
     "Preliminary Offering Circular") and an offering circular, dated December
     2, 1999 (the "Offering Circular") has been prepared in connection with the
     offering of the Securities. Additionally, the Company has previously
     prepared the following documents: the Company's Quarterly Reports on Form
     10-Q for the quarters ended March 31, 1999,
<PAGE>

     June 30, 1999 and September 30, 1999, the Company's Annual Report on Form
     10-K for the year ended December 31, 1998, each of the Company's Current
     Reports on Form 8-K, filed January 29, 1999, February 22, 1999, March 2,
     1999, June 18, 1999, August 11, 1999, October 12, 1999 and November 29,
     1999 and the amendment to the Company's registration statement on Form 8-A
     filed November 29, 1999 (together the "Exchange Act Reports"). Any
     reference (other than in Sections 7(a) hereof) to the Offering Circular
     shall be deemed to refer to and include the Exchange Act Reports, and any
     reference (other than in Section 7(a) hereof) to the Offering Circular as
     amended or supplemented as of any specified date after the date hereof
     shall be deemed to include (i) the Exchange Act Reports and all subsequent
     documents filed with the United States Securities and Exchange Commission
     (the "Commission") pursuant to Section 13(a), 13(c) or 15(d) of the United
     States Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     after the date of the Offering Circular and prior to such specified date
     and (ii) any Additional Issuer Information (as defined in Section 5(f))
     furnished by the Company, prior to the completion of the distribution of
     the Securities. The Exchange Act Reports, when they were filed with the
     Commission, conformed in all material respects to the applicable
     requirements of the Exchange Act and the applicable rules and regulations
     of the Commission thereunder. The Preliminary Offering Circular, the
     Offering Circular and the Exchange Act Reports did not, as of their
     respective dates, contain an untrue statement of a material fact or omit 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;
     provided, however, that this representation and warranty shall not apply to
     any statements or omissions made in reliance upon and in conformity with
     information furnished in writing to the Company by a Purchaser through
     Goldman, Sachs & Co. expressly for use therein. Since September 30, 1999,
     the Company has not filed any documents with the Commission pursuant to
     Section 13(a), 13(c) or 15(d) of the Exchange Act other than the Exchange
     Act Reports;

          (b)  Neither the Company nor any of its subsidiaries has sustained
     since the date of the latest audited financial statements included in the
     Offering Circular any material loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, otherwise than as set forth or contemplated in the Offering
     Circular; and, otherwise than as set forth or contemplated in the Offering
     Circular, since the respective dates as of which information is given in
     the Offering Circular, there has not been any change in the capital stock
     or long-term debt of the Company or any of its subsidiaries or any material
     adverse change, or any development that is reasonably likely to result in a
     material adverse change, in or affecting the general affairs, management,
     financial position, stockholders' equity or results of operations of the
     Company and its subsidiaries;

          (c)  The Company has no subsidiary that is a "Significant Subsidiary"
     of the Company within the meaning of Regulation S-X under the Securities
     Act of 1933, as amended (the "Securities Act"), other than Cohesive
     Technology Solutions, Inc. ("Cohesive");

                                       2
<PAGE>

          (d)  The Company and its subsidiaries own no real property. The
     Company and its subsidiaries have good and marketable title to all personal
     property owned by them, in each case free and clear of all liens,
     encumbrances and defects except such as are described in the Offering
     Circular or such as do not materially affect the value of such property and
     do not interfere with the use made and proposed to be made of such property
     by the Company and its subsidiaries; and any real property and buildings
     held under lease by the Company and its subsidiaries are held by them under
     valid, subsisting and enforceable leases with such exceptions as are not
     material and do not interfere with the use made and proposed to be made of
     such property and buildings by the Company and its subsidiaries;

          (e)  All of the issued shares of capital stock of the Company have
     been duly and validly authorized and issued and are fully paid and non-
     assessable;

          (f)  The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of Delaware, with power and
     authority (corporate and other) to own its properties and conduct its
     business as described in the Offering Circular, and has been duly qualified
     as a foreign corporation for the transaction of business and is in good
     standing under the laws of each other jurisdiction where the failure to be

          Goldman, Sachs & Co. (or such other underwriter as the Company shall
          choose in the event that Goldman, Sachs & Co. shall decline the
          representation of the Company in such offering) and such other of the
          Purchasers as the Company and Goldman, Sachs & Co. shall mutually

     6.   The Company covenants and agrees with the several Purchasers that the

costs and expenses, including the fees of their counsel, transfer taxes on
resale of any of the Securities by them, and any advertising expenses connected

      7.  The obligations of the Purchasers hereunder shall be subject, in their
discretion, to the condition that all representations and warranties and other
statements of the Company herein are, at and as of the Time of Delivery, true
and correct, the condition that the Company shall have performed all of its
obligations hereunder theretofore to be performed, and the following additional
conditions:

     of subsection (b) below as well as such other related matters as you may
     reasonably request, and such counsel shall have received such papers and
     information as they may reasonably request to enable them to pass upon such
     matters;

          (b)  Fenwick & West LLP, counsel for the Company, (or such other

     acceptable to Goldman, Sachs & Co.) shall have furnished to you their
     written opinion, dated the Time of Delivery, in form and substance
     satisfactory to you, to the effect that:

               (i)  The Company has been duly incorporated and is validly

          have been duly and validly authorized and issued, are non-assessable
          and to such counsel's knowledge, are fully paid;

               (iii) The Company has been duly qualified as a foreign
          corporation for the transaction of business and is in good standing
          under the laws of each jurisdiction within the United States in which

          to be so qualified would have a material adverse effect on the
          business, financial condition or results of operations of the Company;

               (iv)  Each significant subsidiary of the Company has been duly
          incorporated and is validly existing as a corporation in good standing

          encumbrances, equities or claims (such counsel being entitled to rely
          in respect of the opinion in this clause upon opinions of local
          counsel and in respect of matters of fact upon certificates of

               (v)   To such counsel's knowledge and other than as set forth in
          the Offering Circular, there are no legal or governmental proceedings
          pending to which the Company or any of its significant subsidiaries is
          a party or of which any property of the Company or any of its
          significant subsidiaries is the subject which, if determined adversely
          to the Company or any of its significant subsidiaries, would
          individually or in the aggregate have a material adverse effect on the
          current or future consolidated financial position, stockholders'
          equity or results of operations of the Company and its significant
          subsidiaries; and, to such counsel's knowledge, no such proceedings
          are threatened by governmental authorities or threatened by others;

          delivered by the Company to you;

               (vii) The Securities have been duly authorized, executed,

<PAGE>

               (viii) The Indenture and the Registration Rights Agreement have
          been duly authorized, executed and delivered by the Company and
          constitute valid and legally binding instruments, enforceable in
          accordance with their respective terms, subject, as to enforcement, to
          bankruptcy, insolvency, reorganization and other laws of general
          applicability relating to or affecting creditors' rights and to
          general equity principles;

               (ix)   The issue and sale of the Securities being delivered at
          the Time of Delivery and the compliance by the Company with all of the
          provisions of the Securities, the Indenture, this Agreement and the
          Registration Rights Agreement and the consummation of the transactions
          herein and therein contemplated were they to be completed on or prior
          to the date of such opinion and assuming the absence of any applicable
          cure period, waiting period or other similar provision, do not
          conflict with or result in a breach or violation of any of the terms
          or provisions of, or constitute a default under, any of the agreements
          filed as exhibits to the Company's or any of its significant
          subsidiaries' Annual Report filed on form 10-K for the year ended
          December 31, 1998, or to any Exchange Act Report or any agreements
          entered into by the Company or any of its significant subsidiaries
          after September 30, 1999 that would be required to be filed as a
          material agreement exhibit on Form 10-Q or any other Exchange Act
          Report (in each case, a "Material Agreement") (provided that in
          determining which documents would be required to be so filed, such
          counsel may rely on an officer's certificate that specifies agreements
          that the Company or any of its significant subsidiaries has entered
          into since September 30, 1999) nor does such action result in any
          violation of the provisions of the Certificate of Incorporation or
          Bylaws of the Company or any of its significant subsidiaries or any
          statute or any order, rule or regulation known to such counsel of any
          court or governmental agency or body having jurisdiction over the
          Company or any of its significant subsidiaries or any of their
          properties;

               (x)    No consent, approval, authorization, order, registration
          or qualification of or with any United States court or United States
          governmental agency or United States body is required for the issue
          and sale of the Securities or the consummation by the Company of the
          transactions contemplated by this Agreement, the Indenture or the
          Registration Rights Agreement, except (A) such consents, approvals,
          authorizations, orders, registrations or qualifications as may be
          required under state securities or Blue Sky laws in connection with
          the purchase and distribution of the Securities by the Purchasers (as
          to which such counsel renders no opinion) or (B) such consents,
          approvals, authorizations, orders, registrations or qualifications as
          are referenced in the Offering Circular;

               (xi)   Neither the Company nor any of its significant
          subsidiaries is in violation of its Certificate of Incorporation or
          Bylaws or, to such counsel's knowledge, in default in the performance
          or observance of any material obligation, agreement, covenant or
          condition contained in any Material Agreement;

                                       14
<PAGE>

               (xii)  The statements set forth in the Offering Circular insofar
          as they purport to constitute a summary of the terms of the
          Securities, the Indenture and the Registration Rights Agreement, and
          under the captions "Certain United States Federal Income Tax
          Considerations" and "Underwriting," insofar as they purport to
          describe the provisions of the laws and documents referred to therein,
          are accurate and complete in all material respects;

               (xiii) The Exchange Act Reports (other than the financial
          statements and related notes and schedules (and financial data)
          therein, as to which such counsel need express no opinion), when they
          were filed with the Commission, complied as to form in all material
          respects with the requirements of the Exchange Act, and the rules and
          regulations of the Commission promulgated thereunder;

               (xiv)  No registration of the Securities under the Securities
          Act, and no qualification of an indenture under the Trust Indenture
          Act of 1939 with respect thereto, is required for the offer and sale
          to, and initial resale of the Securities by, the Purchasers in the
          manner contemplated by this Agreement; and

               (xv)   The Company is not an "investment company," as such term
          is defined in the Investment Company Act.

               In addition, such counsel shall state that, although they are not
          passing upon and do not assume any responsibility for, nor have they
          independently verified, the accuracy, completeness or fairness of the
          statements contained in the Preliminary Offering Circular and the
          Offering Circular, except for and to the extent of those referred to
          in the opinion in subsection (xii) of this Section 7(b),  they have
          participated in certain conferences with officers and other employees
          of the Company, representatives of the Company's independent certified
          public accountants and representatives of the Purchasers with respect
          to the preparation of the Preliminary Offering Circular and the
          Offering Circular, and no facts have come to the attention of
          attorneys devoting attention to the representation of the Company in
          its preparation of the Preliminary Offering Circular and the Offering
          Circular that have caused them to believe that, as of their respective
          dates and as of the Time of Delivery, the Preliminary Offering
          Circular and the Offering Circular or any further amendments thereto
          made by the Company prior to such Time of Delivery (other than the
          financial statements and related notes, related schedules and
          financial data included therein, as to which such counsel need express
          no opinion) 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, in light of the
          circumstances under which they were made, not misleading. Further,
          such counsel shall state that, although they are not passing upon and
          do not assume any responsibility for, nor have they independently
          verified, the accuracy, completeness or fairness of the statements
          contained in the Exchange Act Reports, they have participated in
          certain conferences with officers and other

                                       15
<PAGE>

          employees of the Company, and representatives of the Company's
          independent certified public accountants with respect to the
          preparation of the respective Exchange Act Reports, and no facts have
          come to the attention of attorneys devoting attention to the
          representation of the Company in its preparation of the respective
          Exchange Act Reports that have caused them to believe that as of the
          dates on which the respective Exchange Act Reports were filed with the
          Commission, the Exchange Act Reports (other than the financial
          statements and related notes, related schedules and financial data
          included therein, as to which such counsel need express no opinion)
          contained an untrue statement of material fact or omitted to state a
          material fact required to be stated therein or necessary to make the
          statements therein, in light of the circumstances under which they
          were made when such documents were so filed, not misleading.

          (c)  On the date of the Offering Circular prior to the execution of
     this Agreement and also at the Time of Delivery, KPMG LLP shall have
     furnished to you a letter or letters, dated the respective dates of
     delivery thereof, in form and substance satisfactory to you, to the effect
     set forth in Annex II hereto;

          (d)  (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Offering Circular any loss or interference with its
     business from fire, explosion, flood or other calamity, whether or not
     covered by insurance, or from any labor dispute or court or governmental
     action, order or decree, otherwise than as set forth or contemplated in the
     Offering Circular, and (ii) since the respective dates as of which
     information is given in the Offering Circular there shall not have been any
     change in the capital stock or long-term debt of the Company or any of its
     subsidiaries or any change, or any development involving a prospective
     change, in or affecting the general affairs, management, financial
     position, stockholders' equity or results of operations of the Company and
     its subsidiaries, otherwise than as set forth or contemplated in the
     Offering Circular, the effect of which, in any such case described in
     Clause (i) or (ii), is in the judgment of the Purchasers so material and
     adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Securities on the terms and in the
     manner contemplated in this Agreement and  in the Offering Circular;

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

          (f)  On or after the date hereof there shall not have occurred any of
     the following: (i) a suspension or material limitation in trading in
     securities generally on the New York Stock Exchange; or on NASDAQ; (ii) a
     suspension or material limitation in

                                       16
<PAGE>

     trading in the Company's securities on NASDAQ; (iii) a general moratorium
     on commercial banking activities declared by either Federal or New York or
     California State authorities; (iv) the outbreak or escalation of
     hostilities involving the United States or the declaration by the United
     States of a national emergency or war, if the effect of any such event
     specified in this Clause (iv) in the judgment of the Purchasers makes it
     impracticable or inadvisable to proceed with the public offering or the
     delivery of the Securities on the terms and in the manner contemplated in
     the Offering Circular; or (v) the occurrence of any material adverse change
     in the existing financial, political or economic conditions in the United
     States or elsewhere which, in the judgment of the Purchasers, would
     materially and adversely affect the financial markets or markets for the
     Securities or other debt securities;

          (g)  The Dollar Securities have been designated for trading on PORTAL;

          (h)  The Company shall have furnished to you executed copies of the
     Indenture and the Registration Rights Agreement; and

          (i)  The Company shall have furnished or caused to be furnished to you
     at the Time of Delivery certificates of officers of the Company
     satisfactory to you as to the accuracy of the representations and
     warranties of the Company herein at and as of such Time of Delivery, as to
     the performance by the Company of all of its obligations hereunder to be
     performed at or prior to such Time of Delivery, as to the matters set forth
     in subsection (d) of this Section and as to such other matters as you may
     reasonably request.

     8.   (a)  The Company will indemnify and hold harmless each Purchaser
against any losses, claims, damages or liabilities, joint or several, to which
such Purchaser may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in the Preliminary Offering Circular or
the Offering Circular, or any amendment or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact necessary to make the statements therein not misleading, and will reimburse
each Purchaser for any legal or other expenses reasonably incurred by such
Purchaser in connection with investigating or defending any such action or claim
as such expenses are incurred; provided, however, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in the Preliminary Offering
Circular or the Offering Circular or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Purchaser through Goldman, Sachs & Co. expressly for use therein.

          (b)  Each Purchaser will indemnify and hold harmless the Company
     against any losses, claims, damages or liabilities to which the Company may
     become subject, under the Securities Act or otherwise, insofar as such
     losses, claims, damages or liabilities (or

                                       17
<PAGE>

     actions in respect thereof) arise out of or are based upon an untrue
     statement or alleged untrue statement of a material fact contained in the
     Preliminary Offering Circular or the Offering Circular, or any amendment or
     supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact or necessary to make the
     statements therein not misleading, in each case to the extent, but only to
     the extent, that such untrue statement or alleged untrue statement or
     omission or alleged omission was made in the Preliminary Offering Circular
     or the Offering Circular or any such amendment or supplement in reliance
     upon and in conformity with written information furnished to the Company by
     such Purchaser through Goldman, Sachs & Co. expressly for use therein; and
     will reimburse the Company for any legal or other expenses reasonably
     incurred by the Company in connection with investigating or defending any
     such action or claim as such expenses are incurred.

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

          (d)  If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a) or (b) above in respect of any losses, claims, damages or
     liabilities (or actions in respect thereof) referred to therein, then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages or
     liabilities (or actions

                                       18
<PAGE>

     in respect thereof) in such proportion as is appropriate to reflect the
     relative benefits received by the Company on the one hand and the
     Purchasers on the other from the offering of the Securities. If, however,
     the allocation provided by the immediately preceding sentence is not
     permitted by applicable law or if the indemnified party failed to give the
     notice required under subsection (c) above, then each indemnifying party
     shall contribute to such amount paid or payable by such indemnified party
     in such proportion as is appropriate to reflect not only such relative
     benefits but also the relative fault of the Company on the one hand and the
     Purchasers on the other in connection with the statements or omissions
     which resulted in such losses, claims, damages or liabilities (or actions
     in respect thereof), as well as any other relevant equitable
     considerations. The relative benefits received by the Company on the one
     hand and the Purchasers on the other shall be deemed to be in the same
     proportion as the total net proceeds from the offering (before deducting
     expenses) received by the Company bear to the total underwriting discounts
     and commissions received by the Purchasers, in each case as set forth in
     the Offering Circular. The relative fault shall be determined by reference
     to, among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by the Company on the one hand or the
     Purchasers on the other and the parties' relative intent, knowledge, access
     to information and opportunity to correct or prevent such statement or
     omission. The Company and the Purchasers agree that it would not be just
     and equitable if contribution pursuant to this subsection (d) were
     determined by pro rata allocation (even if the Purchasers were treated as
     one entity for such purpose) or by any other method of allocation which
     does not take account of the equitable considerations referred to above in
     this subsection (d). The amount paid or payable by an indemnified party as
     a result of the losses, claims, damages or liabilities (or actions in
     respect thereof) referred to above in this subsection (d) shall be deemed
     to include any legal or other expenses reasonably incurred by such
     indemnified party in connection with investigating or defending any such
     action or claim. Notwithstanding the provisions of this subsection (d), no
     Purchaser shall be required to contribute any amount in excess of the
     amount by which the total price at which the Securities underwritten by it
     and distributed to investors were offered to investors exceeds the amount
     of any damages which such Purchaser has otherwise been required to pay by
     reason of such untrue or alleged untrue statement or omission or alleged
     omission. The Purchasers' obligations in this subsection (d) to contribute
     are several in proportion to their respective underwriting obligations and
     not joint.

          (e)  The obligations of the Company under this Section 8 shall be in
     addition to any liability which the Company may otherwise have and shall
     extend, upon the same terms and conditions, to each person, if any, who
     controls any Purchaser within the meaning of the Act; and the obligations
     of the Purchasers under this Section 8 shall be in addition to any
     liability which the respective Purchasers may otherwise have and shall
     extend, upon the same terms and conditions, to each officer and director of
     the Company and to each person, if any, who controls the Company within the
     meaning of the Securities Act.

                                       19

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

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

          (c)  If, after giving effect to any arrangements for the purchase of
     the Securities of a defaulting Purchaser or Purchasers by you and the
     Company as provided in subsection (a) above, the aggregate principal amount
     of Securities which remains unpurchased exceeds one-eleventh of the
     aggregate principal amount of all the Securities, or if the Company shall
     not exercise the right described in subsection (b) above to require non-
     defaulting Purchasers to purchase Securities of a defaulting Purchaser or
     Purchasers, then this Agreement shall thereupon terminate, without
     liability on the part of any non-defaulting Purchaser or the Company,
     except for the expenses to be borne by the Company and the Purchasers as
     provided in Section 6 hereof and the indemnity and contribution agreements
     in Section 8 hereof; but nothing herein shall relieve a defaulting
     Purchaser from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Purchasers, as set forth in
this Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and

                                       20
<PAGE>

effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Purchaser or any controlling person of any
Purchaser, or the Company, or any officer or director or controlling person of
the Company, and shall survive delivery of and payment for the Securities.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Purchaser except as
provided in Sections 6 and 8 hereof; but, if for any other reason, the
Securities are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Purchasers through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Purchasers in making preparations for the
purchase, sale and delivery of the Securities, but the Company shall then be
under no further liability to any Purchaser except as provided in Sections 6 and
8 hereof.

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

     13.  All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Purchasers shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 21st Floor, New York, New York 10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the Offering
Circular, Attention: Secretary; provided, however, that any notice to a
Purchaser pursuant to Section 8(c) hereof shall be delivered or sent by mail,
telex or facsimile transmission to such Purchaser at its address set forth in
its Purchasers' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company by you upon request.  Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

     14.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Purchasers, the Company and, to the extent provided in Sections 8 and 10
hereof, the officers and directors of the Company and each person who controls
the Company or any Purchaser, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Securities from any Purchaser shall be deemed a successor or assign by reason
merely of such purchase.

     15.  In respect of any judgment or order given or made for any amount due
hereunder that is expressed and paid in a currency (the "judgment currency")
other than United States dollars, the Company will indemnify each Purchaser
against any loss incurred by such Purchaser as a result of any variation as
between (i) the rate of exchange at which the United States dollar amount is
converted into the judgment currency for the purpose of such judgment or order
and (ii) the rate of exchange at which a Purchaser is able to purchase United
States dollars with the

                                       21
<PAGE>

amount of judgment currency actually received by such Purchaser. The foregoing
indemnity shall constitute a separate and independent obligation of the Company
and shall continue in full force and effect notwithstanding any such judgment or
order as aforesaid. The term "rate of exchange" shall include any premiums and
costs of exchange payable in connection with the purchase of or conversion into
United States dollars.

     16.  Time shall be of the essence of this Agreement.

     17.  This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

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

                                       22

     If the foregoing is in accordance with your understanding, please sign and
return to us ten (10) counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Purchasers, this letter and such acceptance hereof
shall constitute a binding agreement between each of the Purchasers and the
Company.  It is understood that your acceptance of this letter on behalf of each

                                                                         ANNEX I

     (1) The Securities have not been and will not be registered under the
Securities Act and may not be offered or sold within the United States or to, or
for the account or benefit of, U.S. persons except in accordance with Regulation
S under the Securities Act or pursuant to an exemption from the registration
requirements of the Securities Act.  Each Purchaser represents that it has
offered and sold the Securities, and will offer and sell the Securities (i) as
part of their distribution at any time and (ii) otherwise until 40 days after
the later of the commencement of the offering and the Time of Delivery, only in
accordance with Rule 903 of Regulation S or Rule 144A under the Securities Act.
Accordingly, each Purchaser agrees that neither it, its affiliates nor any
persons acting on its or their behalf has engaged or will engage in any directed
selling efforts with respect to the Securities, and it and they have complied
and will comply with the offering restrictions requirement of Regulation S.
Each Purchaser agrees that, at or prior to confirmation of sale of Securities
(other than a sale pursuant to Rule 144A), it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Securities from it during the distribution
compliance period a confirmation or notice to substantially the following
effect:

          "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Securities Act") and may not be offered and
     sold within the United States or to, or for the account or benefit of, U.S.
     persons (i) as part of their distribution at any time or (ii) otherwise
     until 40 days after the later of the commencement of the offering and the
     closing date, except in either case in accordance with Regulation S (or
     Rule 144A if available) under the Securities Act.  Terms used above have
     the meaning given to them by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     Each Purchaser further agrees that it has not entered and will not enter
into any contractual arrangement with respect to the distribution or delivery of
the Securities, except with its affiliates or with the prior written consent of
the Company.

     (2) Notwithstanding the foregoing, Securities may be offered, sold and
delivered by the Purchasers in the United States and to U.S. persons pursuant to
Section 3(a)(i) of this Agreement without delivery of the written statement
required by paragraph (1) above.

     (3) Each Purchaser further represents and agrees that (i) it has not
offered or sold and prior to the date six months after the date of issue of the
Securities will not offer or sell any Securities to persons in the United
Kingdom except to persons whose ordinary activities involve them in acquiring,
holding, managing or disposing of investments (as principal or agent) for the
purposes of their businesses or otherwise in circumstances which have not
resulted and will not result in an offer to the public in the United Kingdom
within the meaning of the Public Offers of Securities Regulations 1995, (b) it
has complied, and will comply, with all applicable provisions
<PAGE>

of the Financial Services Act of 1986 of Great Britain with respect to anything
done by it in relation to the Securities in, from or otherwise involving the
United Kingdom, and (c) it has only issued or passed on and will only issue or
pass on in the United Kingdom any document received by it in connection with the
issuance of the Securities to a person who is of a kind described in Article
11(3) of the Financial Services Act 1986 (Investment Advertisements)
(Exemptions) Order 1996 of Great Britain or is a person to whom the document may
otherwise lawfully be issued or passed on.

     (4) Each Purchaser agrees that it will not offer, sell or deliver any of
the Securities  in any jurisdiction outside the United States except under
circumstances that will result in compliance with the applicable laws thereof,
and that it will take at its own expense whatever action is required to permit
its purchase and resale of the Securities in such jurisdictions.  Each Purchaser
understands that no action has been taken to permit a public offering in any
jurisdiction outside the United States where action would be required for such
purpose.  Each Purchaser agrees not to cause any advertisement of the Securities
to be published in any newspaper or periodical or posted in any public place and
not to issue any circular relating to the Securities, except in any such case
with Goldman, Sachs & Co.'s express written consent and then only at its own
risk and expense.

     Pursuant to Section 7(d) of the Purchase Agreement, the accountants shall
furnish letters to the Purchasers to the effect that:

         (i)   They are independent certified public accountants with respect to
     the Company and its subsidiaries within the meaning of Section 101 of the
     AICPA Code of Professional Conduct;

         (ii)  In our opinion, the consolidated financial statements and
     financial statement schedules audited by us and included in the Offering
     Circular comply as to form in all material respects with the applicable
     requirements of the Exchange Act and the related published rules and
     regulations;

         (iii) The unaudited selected financial information with respect to the
     consolidated results of operations and financial position of the Company
     for the four most recent fiscal years included in the Offering Circular
     agrees with the corresponding amounts (after restatements where applicable)
     in the audited consolidated financial statements for such four fiscal
     years;

         (iv)  On the basis of limited procedures not constituting an audit in
     accordance with generally accepted auditing standards, consisting of a
     reading of the unaudited financial statements and other information
     referred to below, a reading of the latest available interim financial
     statements of the Company and its subsidiaries, inspection of the minute
     books of the Company and its subsidiaries since the date of the latest
     audited financial statements included in the Offering Circular, inquiries
     of officials of the Company and its subsidiaries responsible for financial
     and accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:

               (A) the unaudited consolidated statements of income, consolidated
         balance sheets and consolidated statements of cash flows included in
         the Offering Circular are not in conformity with generally accepted
         accounting principles applied on the basis substantially consistent
         with the basis for the audited condensed consolidated statements of
         income, consolidated balance sheets and consolidated statements of cash
         flows included in the Offering Circular;

               (B) any other unaudited income statement data and balance sheet
         items included in the Offering Circular do not agree with the
         corresponding items in the unaudited consolidated financial statements
         from which such data and items were derived, and any such unaudited
         data and items were not determined on a basis substantially consistent
         with the basis for the corresponding amounts in the audited
         consolidated financial statements included in the Offering Circular;

<PAGE>

            (C) the unaudited financial statements which were not included in
          the Offering Circular but from which were derived any unaudited
          condensed financial statements referred to in Clause (A) and any
          unaudited income statement data and balance sheet items included in
          the Offering Circular and referred to in Clause (B) were not
          determined on a basis substantially consistent with the basis for the
          audited consolidated financial statements included in the Offering
          Circular;

            (D) any unaudited pro forma consolidated condensed financial
          statements included in the Offering Circular do not comply as to form
          in all material respects with the applicable accounting requirements
          or the pro forma adjustments have not been properly applied to the
          historical amounts in the compilation of those statements;

            (E) as of a specified date not more than five days prior to the date
          of such letter, there have been any changes in the consolidated
          capital stock (other than issuances of capital stock upon exercise of
          options and stock appreciation rights, upon earn-outs of performance
          shares and upon conversions of convertible securities, in each case
          which were outstanding on the date of the latest financial statements
          included in the Offering Circular or any increase in the consolidated
          long-term debt of the Company and its subsidiaries, or any decreases
          in consolidated net current assets or stockholders' equity or other
          items specified by the Purchasers, or any increases in any items
          specified by the Purchasers, in each case as compared with amounts
          shown in the latest balance sheet included in the Offering Circular
          except in each case for changes, increases or decreases which the
          Offering Circular discloses have occurred or may occur or which are
          described in such letter; and

            (F) for the period from the date of the latest financial statements
          included in the Offering Circular to the specified date referred to in
          Clause (E) there were any decreases in consolidated net revenues or
          operating profit or the total or per share amounts of consolidated net
          income or other items specified by the Purchasers, or any increases in
          any items specified by the Purchasers, in each case as compared with
          the comparable period of the preceding year and with any other period
          of corresponding length specified by the Purchasers, except in each
          case for decreases or increases which the Offering Circular discloses
          have occurred or may occur or which are described in such letter; and

         (v) In addition to the examination referred to in their report(s)
     included in the Offering Circular and the limited procedures, inspection of
     minute books, inquiries and other procedures referred to in paragraphs
     (iii) and (iv) above, they have carried out certain specified procedures,
     not constituting an audit in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Purchasers, which are derived from the general
     accounting records of the Company and its subsidiaries, which appear in the
     Offering Circular, and
<PAGE>

     have compared certain of such amounts, percentages and financial
     information with the accounting records of the Company and its subsidiaries
     and have found them to be in agreement.

(incorporated by reference) in the Offering Circular.  This review process,
applied to the information relation to the issue, is (will be) substantially
consistent with the due diligence review process that we would perform if this
placement of securities were being registered pursuant to the Securities Act of
1933 (the Act).  It is recognized however that what is "substantially
consistent" may vary from situation to situation and may not be the same as that
done in a registered offering of the same securities for the same issuer and
whether the procedures being, or to be, followed will be "substantially
consistent" will be determined by us on a case-by-case basis.  We are
knowledgeable with respect to the due diligence review process that would be
performed if this placement of securities were being registered pursuant to the
Act.  We hereby request that you deliver to us a "comfort" letter concerning the
financial statements of the issuer and certain statistical and other data
included in the offering document.  We will contact you to identify the
procedures we wish you to follow and the form we wish the comfort letter to
take.

                                    Very truly yours,


                                    .........................................

     2.  Registration Under the Securities Act.

     (a) Except as set forth in Section 2(b) below, the Company agrees to file
with the Commission, as soon as practicable after the Closing Date, but no later
than 60 days after the Closing Date, a registration statement relating to an
offer to exchange (such registration statement, the "Exchange Offer Registration
Statement", and such offer, the "Exchange Offer") any and all of the Securities
for a like aggregate principal amount of debt securities issued by the Company,
which debt securities are substantially identical to the Securities (and are
entitled to the benefits of a trust indenture which is substantially identical
to the Indenture or is the Indenture and which has been qualified under the
Trust Indenture Act), except that they have been registered pursuant to an
effective registration statement under the Act and do not contain provisions for
liquidated damages contemplated in Section 2(c) below (such new debt securities
hereinafter called "Exchange Securities").  The Company agrees to use its best
efforts to cause the Exchange Offer Registration Statement to become effective
under the Act as soon as practicable, but no later than 150 days after the
Closing Date.  The Exchange Offer will be registered under the Act on the
appropriate form and will comply with all applicable tender offer rules and
regulations under the Exchange Act.  Unless the Exchange Offer would not be
permitted by applicable law or Commission policy, the Company further agrees to
use its best efforts (i) to complete the Exchange Offer promptly, but no later
than 30 Business Days after the Exchange Offer Registration Statement becomes
effective or is declared effective by the Commission, (ii) to hold the Exchange
Offer open for a period of not less than the minimum period required under
applicable federal and state securities laws, provided however, that in no event
shall such period be less than 20 Business Days after the mailing of notice to
holders of such Exchange Offer Registration Statement being declared effective,
and (iii) to issue Exchange Securities for all Transfer Restricted Securities
that have been properly tendered and not withdrawn on or prior to the expiration
of the Exchange Offer.  The Exchange Offer will be deemed to have been
"completed" only if the debt securities received by holders other than
Restricted Holders in the Exchange Offer for Transfer Restricted Securities are,
upon receipt, transferable by each such holder without need for further
compliance with Section 5 of the Act and the Exchange Act (except for the
requirement to deliver a Prospectus included in the Exchange Offer Registration
Statement applicable to resales by Broker-Dealers of Exchange Securities
received by such Broker-Dealer pursuant to an Exchange Offer in exchange for
Transfer Restricted Securities other than those acquired by the Broker-Dealer
directly from the Company), and without material restrictions under the blue sky
or securities laws of a substantial majority of the States of the United States
of America.  The Exchange Offer shall be deemed to have been completed upon the
earlier to occur of (i) the Company having exchanged the Exchange Securities for
all outstanding Transfer Restricted Securities pursuant to the Exchange Offer
and (ii) the Company having exchanged, pursuant to the Exchange Offer, Exchange
Securities for all Transfer Restricted Securities that have been properly
tendered and not withdrawn before the expiration of the Exchange Offer.  If the
Company is notified prior to the completion of the Exchange Offer by a Broker-
Dealer that is a holder of Transfer

                                      -4-
<PAGE>

Restricted Securities (other than Transfer Restricted Securities received by the
Broker-Dealer directly from the Company), then the Company agrees (x) to include
in the Exchange Offer Registration Statement a Prospectus for use in connection
with any resales of Exchange Securities by a Broker-Dealer, other than resales
of Exchange Securities received by a Broker-Dealer pursuant to an Exchange Offer
in exchange for Transfer Restricted Securities acquired by the Broker-Dealer
directly from the Company, and (y) to keep such Exchange Offer Registration
Statement effective for a period (the "Resale Period") beginning when Exchange
Securities are first issued in the Exchange Offer and ending upon the earlier of
the expiration of the 180th day after the Exchange Offer has been completed or
such time as such Broker-Dealers no longer own any Transfer Restricted
Securities. With respect to such Exchange Offer Registration Statement, each
Broker-Dealer that holds Exchange Securities received in an Exchange Offer in
exchange for Transfer Restricted Securities not acquired by it directly from the
Company shall have the benefit of the rights of indemnification and contribution
set forth in Sections 6(a), (c), (d) and (e) hereof.


     (b) If (i) the Company is not permitted to consummate the Exchange Offer
because the Exchange Offer is not permitted by applicable law or Commission
policy or (ii) any holder of Transfer Restricted Securities notifies the Company
prior to the 20th day following completion of the Exchange Offer that (A) it is
prohibited by law or Commission policy from participating in the Exchange Offer
or (B) that it may not resell in compliance with the Act or Commission policy
the Exchange 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 or
(C) that it is a Broker-Dealer and owns Securities acquired directly from the
Company or an Affiliate, then in lieu of conducting the Exchange Offer for such
Transfer Restricted Securities contemplated by Section 2(a) the Company shall
use its best efforts to file with the Commission as soon as practicable, but no
later than 45 days after the date on which the Company determines that it is not
permitted to file the Exchange Offer Registration Statement pursuant to clause
(i) above or 45 days after the date on which the Company receives the notice
specified in clause (ii) above (but in either case, in no event less than 60
days after the Closing Date), a "shelf" registration statement providing for the
registration of, and the sale on a continuous or delayed basis by the holders
of, all of the Transfer Restricted Securities, pursuant to Rule 415 or any
similar rule that may be adopted by the Commission, which may be an amendment to
the Exchange Offer Registration Statement (such filing, the "Shelf Registration"
and such registration statement, the "Shelf Registration Statement").  The
Company agrees to use its best efforts (i) to cause the Shelf Registration
Statement to become or be declared effective by the Commission on or prior to 90
days after such obligation arises (but in no event less than 150 days after the
Closing Date) and to keep such Shelf Registration Statement continuously
effective in order to permit the Prospectus forming a part thereof to be usable
by holders for resales of Transfer Restricted Securities for a period ending on
the earlier of the second anniversary of the Effective Time or such time as
there are no longer any Transfer Restricted Securities outstanding, provided,
however, that no holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement or to use the Prospectus
forming a part thereof for resales of Transfer Restricted Securities unless such
holder is an Electing Holder, and (ii) after the Effective Time of the Shelf
Registration Statement, promptly upon the request of any holder of Transfer
Restricted Securities that is not then an Electing Holder, to take any action
reasonably necessary to enable such holder to use the Prospectus forming a part

                                      -5-
<PAGE>

thereof for resales of Transfer Restricted Securities, including, without
limitation, any action necessary to identify such holder as a selling
securityholder in the Shelf Registration Statement, provided, however, that
nothing in this Clause (ii) shall relieve any such holder of the obligation to
return a completed and signed Notice and Questionnaire to the Company in
accordance with Section 3(d)(iii) hereof.  No holder of Securities shall be
entitled to Liquidated Damages pursuant to 2(c) hereof unless and until such
holder shall have provided all such information.  The Company further agrees to
supplement or make amendments to the Shelf Registration Statement, as and when
required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration Statement or
by the Act or rules and regulations thereunder for shelf registration, and the
Company agrees to furnish to each Electing Holder copies of any such supplement
or amendment prior to its being used or promptly following its filing with the
Commission.

     (c) In the event that (i) the Company has not filed the Exchange Offer
Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section
2(a) or 2(b), respectively, or (ii) such Exchange Offer Registration Statement
or Shelf Registration Statement has not become effective or been declared
effective by the Commission on or before the date on which such registration
statement is required to become or be declared effective pursuant to Section
2(a) or 2(b), respectively, or (iii) the Exchange Offer has not been completed
within 30 Business Days after the initial effective date of the Exchange Offer
Registration Statement relating to the Exchange Offer (if the Exchange Offer is
then required to be made) or (iv) any Exchange Offer Registration Statement or
Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed
and declared effective, but shall thereafter cease to be effective or usable in
connection with resales of Transfer Restricted Securities during the periods
specified in Section 2(a) or 2(b), respectively, (except as specifically
permitted herein, including pursuant to Sections 3(c)(ii) and (iv) and 3(d)(iv)
and 3(e)) without being succeeded immediately by an additional registration
statement filed and declared effective (each such event referred to in clauses
(i) through (iv), a "Registration Default" and each period during which a
Registration Default has occurred and is continuing, a "Registration Default
Period"), then, the Company will pay liquidated damages to each holder of
Transfer Restricted Securities affected thereby (such liquidated damages, the
"Liquidated Damages"), with respect to the first 90-day period immediately
following the occurrence of the first Registration Default in an amount equal to
$0.05 per week such Registration Default continues per $1,000 principal amount
of Transfer Restricted Securities held by such holder.  The amount of the
Liquidated Damages will increase by an additional $0.05 per week such
Registration Default continues per $1,000 principal amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages for all Registration Defaults of $0.25 per week per $1,000 principal
amount of Transfer Restricted Securities.  Notwithstanding the foregoing, the
Company shall in no event be required to pay Liquidated Damages for more than
one Registration Default at any time.  All accrued Liquidated Damages will be
paid by the Company on each Interest Payment Date (as defined in the Indenture)
to each holder of any Transfer Restricted Securities by wire transfer of
immediately available funds or by federal funds check and to holders of Transfer
Restricted Securities by wire transfer to the accounts specified by them or by
mailing checks to their registered addresses if no such accounts have been

                                      -6-
<PAGE>

specified. Following the cure of all Registration Defaults, the accrual of
Liquidated Damages will cease. No other damages shall be available to holders of
Transfer Restricted Securities for any Registration Default.

     (d) Any reference herein to a registration statement as of any time shall
be deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time and any reference herein to any post-
effective amendment to a registration statement as of any time shall be deemed
to include any document incorporated, or deemed to be incorporated, therein by
reference as of such time.

     3.  Registration Procedures.

     If the Company files a registration statement pursuant to Section 2(a) or
Section 2(b), the following provisions shall apply:

     (a) At or before the Effective Time of the Exchange Offer or the Shelf
Registration, as the case may be, the Company shall qualify the Indenture under
the Trust Indenture Act of 1939.

     (b) In the event that such qualification would require the appointment of a
new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture.

     (c) In connection with the Company's obligations with respect to the
registration of Exchange Securities as contemplated by Section 2(a) (the
"Exchange Registration"), if applicable, the Company shall, as soon as
practicable (or as otherwise specified):

          (i) prepare and file with the Commission, as soon as practicable but
     no later than 60 days after the Closing Date, an Exchange Offer
     Registration Statement on any form which may be utilized by the Company and
     which shall permit the Exchange Offer and, if applicable, resales of
     Exchange Securities by Broker-Dealers during the Resale Period to be
     effected as contemplated by Section 2(a), and use its best efforts to cause
     such Exchange Offer Registration Statement to become effective as soon as
     practicable thereafter, but no later than 150 days after the Closing Date;

          (ii) as soon as practicable prepare and file with the Commission such
     amendments and supplements to such Exchange Offer Registration Statement
     and the Prospectus included therein as may be necessary to effect and
     maintain the effectiveness of such Exchange Offer Registration Statement
     for the periods and purposes contemplated in Section 2(a) hereof and as may
     be required by the applicable rules and regulations of the Commission and
     the instructions applicable to the form of such Exchange Offer Registration
     Statement, and promptly provide each Broker-Dealer holding Exchange
     Securities with such number of copies of the Prospectus included therein
     (as then amended or supplemented), in conformity in all material respects
     with the requirements of the Act and the Trust Indenture Act and the rules
     and regulations of the Commission thereunder, as such Broker-Dealer
     reasonably may

                                      -7-
<PAGE>

     request prior to the expiration of the Resale Period, for use in connection
     with resales of Exchange Securities; provided that upon the occurrence of
     any event that would cause any such Exchange Offer 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, either of which occurs during the period that the
     Company is required to maintain an effective and usable Exchange Offer
     Registration Statement and Prospectus pursuant to this Agreement, the
     Company shall file promptly an appropriate amendment or supplement to such
     Registration Statement or Prospectus, (1) in the case of clause (A),
     correcting any such misstatement or omission, and (2) in the case of
     clauses (A) and (B) use its best efforts to cause any amendment to be
     declared effective and such Exchange Offer Registration Statement and the
     Prospectus to become usable for their intended purpose(s) as soon as
     practicable thereafter; provided further notwithstanding anything to the
     contrary set forth in this Agreement, during the 180 day period following
     completion of the Exchange Offer, the Company's obligations to use its best
     efforts to keep the Exchange-Offer Registration Statement continuously
     effective, supplemented and amended shall be suspended in the event
     continued effectiveness of the Exchange-Offer Registration Statement would,
     with the advice of counsel to the Company, make it advisable for the
     Company to disclose a material financing, acquisition or other corporate
     transaction, and the Board of Directors shall have determined in good faith
     that such disclosure is not in the best interests of the Company, but in no
     event will any such suspension, individually or in the aggregate, exceed
     sixty (60) days (such suspensions being referred to herein as an "Exchange
     Suspension Period");

          (iii) promptly notify in writing each Broker-Dealer that has requested
     or received from the Company copies of the Prospectus included in such
     Exchange Offer Registration Statement and issue a Press Release indicating
     the same, (A) when such Exchange Offer Registration Statement or the
     Prospectus included therein or any Prospectus amendment or supplement or
     post-effective amendment has been filed, and, with respect to such Exchange
     Offer Registration Statement or any post-effective amendment, when the same
     has become effective, (B) of the issuance by the Commission of any stop
     order suspending the effectiveness of such Exchange Offer Registration
     Statement or the initiation or threatening of any proceedings for that
     purpose, (C) of the receipt by the Company of any notification with respect
     to the suspension of the qualification of the Exchange Securities for sale
     in any jurisdiction or the initiation or threatening of any proceeding for
     such purpose, or (D) at any time during the Resale Period when a Prospectus
     is required to be delivered under the Act, that such Exchange Offer
     Registration Statement, Prospectus, Prospectus amendment or supplement or
     post-effective amendment does not conform in all material respects to the
     applicable requirements of the Act and the Trust Indenture Act and the
     rules and regulations of the Commission thereunder or contains an untrue
     statement of a material fact or omits to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing.  Each holder of
     Transfer Restricted Securities agrees that upon receipt of any notice from
     the Company pursuant to this Section 3(c)(iii)(D), such holder shall
     forthwith discontinue the disposition of Transfer Restricted Securities
     pursuant to the Exchange Offer Registration Statement applicable to such
     Transfer

                                      -8-
<PAGE>

     Restricted Securities until such Broker-Dealer shall have received copies
     of such amended or supplemented Prospectus, and if so directed by the
     Company, such Broker-Dealer shall deliver to the Company (at the Company's
     expense) all copies, other than permanent file copies, then in such Broker-
     Dealer's possession of the Prospectus covering such Transfer Restricted
     Securities at the time of receipt of such notice;

          (iv) in the event that the Company would be required, pursuant to
     Section 3(c)(iii)(D) above, to notify any Broker-Dealers holding Exchange
     Securities, without unreasonable delay, subject to Section 3(c)(ii),
     prepare and furnish to each such holder a reasonable number of copies of a
     Prospectus supplemented or amended so that, as thereafter delivered to
     purchasers of such Exchange Securities during the Resale Period, such
     Prospectus shall conform in all material respects to the applicable
     requirements of the Act and the Trust Indenture Act and the rules and
     regulations of the Commission thereunder and shall not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing;

          (v) subject to the provisos in (ii) above, use its best efforts to
     obtain the withdrawal of any order suspending the effectiveness of such
     Exchange Offer Registration Statement or any post-effective amendment
     thereto at the earliest practicable date;

          (vi) use its best efforts to (A) register or qualify the Exchange
     Securities under the securities laws or blue sky laws of such jurisdictions
     as are contemplated by Section 2(a) no later than the commencement of the
     Exchange Offer, (B) if applicable, keep such registrations or
     qualifications in effect and comply with such laws so as to permit the
     continuance of offers, sales and dealings therein in such jurisdictions
     until the expiration of the Resale Period and (C) take any and all other

     best efforts to keep the Shelf Registration Statement continuously

     continued effectiveness of the Shelf Registration Statement would, with the
     advice of counsel to the Company, make it advisable for the Company to
     disclose a material financing, acquisition or other corporate transaction,
     and the Board of Directors shall have determined in good faith that such
     disclosure is not in the best interests of the Company, but in no event
     will any such suspension, individually or in the aggregate, exceed ninety
     (90) days in any calendar year (such suspensions being referred to herein

notify the Company as promptly as practicable of any inaccuracy or change in
information previously furnished by such Electing Holder to the Company or of
the occurrence of any event in either case as a result of which any Prospectus
relating to such Shelf Registration contains or would contain an untrue
statement of a material fact regarding such Electing Holder or such Electing
Holder's intended method of disposition of such Transfer Restricted Securities
or omits to state any material fact regarding such Electing Holder or such
Electing Holder's intended method of disposition of such Transfer Restricted
Securities required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing, and promptly
to furnish to the Company any additional information required to correct and
update any previously furnished information or required so that such Prospectus
shall not contain, with respect to such Electing Holder or the disposition of
such Transfer Restricted Securities, an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then
existing.

     (g)  Until the expiration of two years after the Closing Date, the Company
will not resell, and will use its best efforts to prevent any of its Af filiates
from reselling, any of the Securities that have been reacquired by any of them
except pursuant to an effective registration statement under the Act.

     (h)  As a condition to its participation in the Exchange Offer pursuant to
the terms of this Agreement, each holder of Transfer Restricted Securities shall
furnish, upon the written request of the Company, prior to the completion 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 Exchange
Securities to be issued in the Exchange Offer and (C) it is acquiring the
Exchange Securities in its ordinary course of business.  Each Holder hereby
acknowledges and agrees that any Broker-Dealer and any such holder using the
Exchange Offer to participate in a distribution of the securities to be acquired
in the Exchange Offer (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, 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 (which may be the Exchange Offer Registration Statement) containing
the selling security holder information required by Item 507 or 508, as
applicable, of Regulation S-K if the resales are of Exchange Securities obtained
by such Holder in exchange for securities acquired by such holder directly from
the Company or an affiliate thereof.

     4.   Registration Expenses.

     The Company agrees to bear and to pay or cause to be paid promptly all
expenses incident to the Company's performance of or compliance with this
Exchange and Registration Rights Agreement, including (a) all Commission and any
NASD registration, filing and review fees and expenses including fees and
disbursements of counsel for the placement or sales agent or underwriters in
connection with such NASD registration, filing and review, (b) all fees and
expenses in connection with the qualification of the Securities for offering and
sale under the State securities and blue sky laws referred to in Section
3(d)(xii) hereof and determination of their eligibility for investment under the
laws of such jurisdictions as any managing underwriters or the Electing Holders
may designate, including any fees and disbursements of counsel for the Electing
Holders (subject to the limitations of Clause (i) below) or underwriters in
connection with such qualification and determination, (c) all expenses relating
to the preparation, printing, production, distribution and reproduction of each
registration statement required to be filed hereunder, each Prospectus included

                                      -18-
<PAGE>

telephone and delivery expenses relating to the offering, sale or delivery of
Securities and the preparation of documents referred in clause (c) above, (e)
fees and expenses of the Trustee under the Indenture, any agent of the Trustee
and any counsel for the Trustee and of any collateral agent or custodian, (f)
internal expenses (including all salaries and expenses of the Company's officers
and employees performing legal or accounting duties), (g) fees, disbursements
and expenses of counsel and independent certified public accountants of the
Company (including the expenses of any opinions or "comfort" letters required by

3(d)(xix) hereof, (i) fees, disbursements and expenses of one counsel for the
Electing Holders retained in connection with a Shelf Registration, as selected
by the Electing Holders of at least a majority in aggregate principal amount of
the Transfer Restricted Securities held by Electing Holders (which counsel shall
be reasonably satisfactory to the Company), (j) any fees charged by securities
rating services for rating the Securities, and (k) fees, expenses and
disbursements of any other persons, including special experts, retained by the
Company in connection with such registration (collectively, the "Registration
Expenses"). To the extent that any Registration Expenses are incurred, assumed
or paid by any holder of Transfer Restricted Securities or any placement or
sales agent therefor or underwriter thereof, the Company shall reimburse such
person for the full amount of the Registration Expenses so incurred, assumed or
paid promptly after receipt of a request therefor. Notwithstanding the
foregoing, the holders of the Transfer Restricted Securities being registered
shall pay all agency fees and commissions and underwriting discounts and
commissions attributable to the sale of such Transfer Restricted Securities and
the fees and disbursements of any counsel or other advisors or experts retained
by such holders (severally or jointly), other than the counsel and experts
specifically referred to above.


     5.   Representations and Warranties.

     The Company represents and warrants to, and agrees with, each Initial
Purchaser and each of the holders from time to time of Transfer Restricted
Securities that:

          (a)  Each registration statement covering Transfer Restricted
     Securities and each Prospectus (including any preliminary or summary
     Prospectus) contained therein or furnished pursuant to Section 3(d) or
     Section 3(c) hereof and any further amendments or supplements to any such
     registration statement or Prospectus, when it becomes effective or is filed
     with the Commission, as the case may be, and, in the case of an
     underwritten offering of Transfer Restricted Securities, at the time of the
     closing under the underwriting agreement relating thereto, will conform in
     all material respects to the applicable requirements of the Act and the
     Trust Indenture Act and the rules and regulations of the Commission
     thereunder and will not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading; and at all times subsequent to
     the Effective Time when a Prospectus would be required to be delivered
     under the Act, other than from (i) such time as a notice has been given to
     holders of Transfer Restricted Securities pursuant to Section 3(d)(viii)(D)
     or Section 3(c)(iii)(D) hereof until (ii) such time as the Company
     furnishes an amended or supplemented Prospectus pursuant to Section 3(e) or
     Section 3(c)(iv) hereof, each such registration statement, and each
     Prospectus (including any summary Prospectus) contained therein or
     furnished pursuant to

                                      -19-
<PAGE>

     Section 3(d) or Section 3(c) hereof, as then amended or supplemented, will
     conform in all material respects to the applicable requirements of the Act
     and the Trust Indenture Act and the rules and regulations of the Commission
     thereunder and will not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing; provided, however, that this representation
     and warranty shall not apply to any statements or omissions made in
     reliance upon and in conformity with information furnished in writing to
     the Company by a holder of Transfer Restricted Securities expressly for use
     therein.

          (b)  Any documents incorporated by reference in any Prospectus
     referred to in Section 5(a) hereof, when they become or became effective or
     are or were filed with the Commission, as the case may be, will conform or
     conformed in all material respects to the requirements of the Act or the
     Exchange Act, as applicable, and none of such documents will at such time
     contain or contained an untrue statement of a material fact or will omit or
     omitted to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading; provided, however, that this
     representation and warranty shall not apply to any statements or omissions
     made in reliance upon and in conformity with information furnished in
     writing to the Company by a holder of Transfer Restricted Securities
     expressly for use therein.

          (c)  The compliance by the Company with all of the provisions of this
     Exchange and Registration Rights Agreement and the consummation of the
     transactions herein contemplated will not conflict with or result in a
     breach of any of the terms or provisions of, or constitute a default under,
     any material indenture, mortgage, deed of trust, loan agreement or other
     agreement or instrument to which the Company or any subsidiary of the
     Company is a party or by which the Company or any subsidiary of the Company
     is bound or to which any of the property or assets of the Company or any
     subsidiary of the Company is subject, nor will such action result in any
     violation of the provisions of the certificate of incorporation, as
     amended, or the by-laws of the Company or any statute or any order, rule or
     regulation of any court or governmental agency or body having jurisdiction
     over the Company or any subsidiary of the Company or any of their
     properties; and no consent, approval, authorization, order, registration or
     qualification of or with any such court or governmental agency or body is
     required for the consummation by the Company of the transactions
     contemplated by this Exchange and Registration Rights Agreement, except the
     registration under the Act of the Securities, qualification of the
     Indenture under the Trust Indenture Act and such consents, approvals,
     authorizations, registrations or qualifications as may be required under
     State securities or blue sky laws in connection with the offering and
     distribution of the Securities.

          (d)  This Exchange and Registration Rights Agreement has been duly
     authorized, executed and delivered by the Company.

     6.  Indemnification.

                                      -20-
<PAGE>

     (a)  Indemnification by the Company.  The Company shall indemnify and hold
harmless each of the holders of Transfer Restricted Securities included in an
Exchange Offer Registration Statement, each of the Electing Holders of Transfer
Restricted Securities included in a Shelf Registration Statement and each person
who participates as a placement or sales agent or as an underwriter in any
offering or sale of such Transfer Restricted Securities against any losses,
claims, damages or liabilities, joint or several, to which such holder, agent or
underwriter may become subject under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Exchange Offer Registration Statement or Shelf
Registration Statement, as the case may be, under which such Transfer Restricted
Securities were registered under the Act, or any preliminary, final or summary
Prospectus contained therein or furnished by the Company to any such holder,
Electing Holder, agent or underwriter, or any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and the Company shall, and it hereby agrees
to, reimburse such holder, such Electing Holder, such agent and such underwriter
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable to any such
person in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
or preliminary, final or summary Prospectus, or amendment or supplement thereto,
in reliance upon and in conformity with written information furnished to the
Company by such person expressly for use therein;

     (b)  Indemnification by the Holders and any Agents and Underwriters.  The
Company may require, as a condition to including any Transfer Restricted
Securities in any registration statement filed pursuant to Section 2(b) hereof
and to entering into any underwriting agreement with respect thereto, that the
Company shall have received an undertaking reasonably satisfactory to it from
the Electing Holder of such Transfer Restricted Securities and from each
underwriter named in any such underwriting agreement, severally and not jointly,
to (i) indemnify and hold harmless the Company, and all other holders of
Transfer Restricted Securities, against any losses, claims, damages or
liabilities to which the Company or such other holders of Transfer Restricted
Securities may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in such registration statement, or any preliminary,
final or summary Prospectus contained therein or furnished by the Company to any
such Electing Holder, agent or underwriter, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Electing Holder or underwriter
expressly for use therein, and (ii) reimburse the Company for any legal or other
expenses reasonably incurred by the Company in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
however, that no such Electing Holder

                                      -21-
<PAGE>

shall be required to undertake liability to any person under this Section 6(b)
for any amounts in excess of the dollar amount of the proceeds to be received by
such Electing Holder from the sale of such Electing Holder's Transfer Restricted
Securities pursuant to such registration.

     (c)  Notices of Claims, Etc.  Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party pursuant to the indemnification provisions of
or contemplated by this Section 6, notify such indemnifying party in writing of
the commencement of such action; but the omission so to notify the indemnifying
party shall not relieve it from any liability which it may have to any
indemnified party other than under the indemnification provisions of or
contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be
brought against any indemnified party and it shall notify an indemnifying party
of the commencement thereof, such indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, such indemnifying party shall
not be liable to such indemnified party for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party.

     (d)  Contribution.  If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations.  The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 6(d) were determined by
pro rata allocation (even if the holders or any agents or underwriters or all of
them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the

                                      -22-
<PAGE>

equitable considerations referred to in this Section 6(d). The amount paid or
payable by an indemnified party as a result of the losses, claims, damages, or
liabilities (or actions in respect thereof) referred to above shall be deemed to
include any legal or other fees or expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 6(d), no holder shall
be required to contribute any amount in excess of the amount by which the dollar
amount of the proceeds received by such holder from the sale of any Transfer
Restricted Securities (after deducting any fees, discounts and commissions
applicable thereto) exceeds 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, and no underwriter shall be required
to contribute any amount in excess of the amount by which the total price at
which the Transfer Restricted Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The holders' and any underwriters' obligations in
this Section 6(d) to contribute shall be several in proportion to the principal
amount of Transfer Restricted Securities registered or underwritten, as the case
may be, by them and not joint.

     (e)  The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each officer, director and partner of
each holder, agent and underwriter and each person, if any, who controls any
holder, agent or underwriter within the meaning of the Act; and the obligations
of the holders and any agents or underwriters contemplated by this Section 6
shall be in addition to any liability which the respective holder, agent or
underwriter may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company (including any person
who, with his consent, is named in any registration statement as about to become
a director of the Company) and to each person, if any, who controls the Company
within the meaning of the Act.

     7.   Underwritten Offerings.

     (a)  Selection of Underwriters.  If any of the Transfer Restricted
Securities covered by the Shelf Registration are to be sold pursuant to an
underwritten offering, the managing underwriter or underwriters thereof shall be
designated by Electing Holders holding at least a majority in aggregate
principal amount of the Transfer Restricted Securities to be included in such
offering, provided that such designated managing underwriter or underwriters is
or are reasonably acceptable to the Company.

     (b)  Participation by Holders.  Each holder of Transfer Restricted
Securities hereby agrees with each other such holder that no such holder may
participate in any underwritten offering hereunder unless such holder (i) agrees
to sell such holder's Transfer Restricted Securities on the basis provided in
any underwriting arrangements approved by the persons entitled hereunder to
approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney,

                                      -23-
<PAGE>

indemnities, underwriting agreements and other documents reasonably required
under the terms of such underwriting arrangements.

     8.   Rule 144.

     The Company covenants to the holders of Transfer Restricted Securities that
to the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Act (including the reports under Section 13 and 15(d) of the Exchange Act
referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under
the Act) and the rules and regulations adopted by the Commission thereunder, and
shall take such further action as any holder of Transfer Restricted Securities
may reasonably request, all to the extent required from time to time to enable
such holder to sell Transfer Restricted Securities without registration under
the Act within the limitations of the exemption provided by Rule 144 under the
Act, as such Rule may be amended from time to time, or any similar or successor
rule or regulation hereafter adopted by the Commission.  Upon the request of any
holder of Transfer Restricted Securities in connection with that holder's sale
pursuant to Rule 144, the Company shall deliver to such holder a written
statement as to whether it has complied with such requirements.

     9.   Miscellaneous.

     (a)  No Inconsistent Agreements.  The Company represents, warrants,
covenants and agrees that it has not granted, and shall not grant, registration
rights with respect to Transfer Restricted Securities or any other securities
which would be inconsistent with the terms contained in this Exchange and
Registration Rights Agreement.

     (b)  Specific Performance.  The parties hereto acknowledge that there would
be no adequate remedy at law if the Company fails to perform any of their
respective obligations hereunder and that the Initial Purchasers and the holders
from time to time of the Transfer Restricted Securities may be irreparably
harmed by any such failure, and accordingly agree that the Initial Purchasers
and such holders, in addition to any other remedy to which they may be entitled
at law or in equity, shall be entitled to compel specific performance of the
respective obligations of the Company under this Exchange and Registration
Rights Agreement in accordance with the terms and conditions of this Exchange
and Registration Rights Agreement, in any court of the United States or any
State thereof having jurisdiction.

     (c)  Notices.  All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally or by courier, or
three days after being deposited in the mail (registered or certified mail,
postage prepaid, return receipt requested) as follows:

     (d)  Parties in Interest.  All the terms and provisions of this Exchange
and Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders from

and assigns of the parties hereto and such holders. In the event that any
transferee of any holder of Transfer Restricted Securities shall acquire
Transfer Restricted Securities, in any manner, whether by gift, bequest,
purchase, operation of law or otherwise, such transferee shall, without any
further writing or action of any kind, be deemed a beneficiary hereof for all
purposes and such Transfer Restricted Securities shall be held subject to all of
the terms of this Exchange and Registration Rights Agreement, and by taking and
holding such Transfer Restricted Securities such transferee shall be entitled to
receive the benefits of, and be conclusively deemed to have agreed to be bound
by all of the applicable terms and provisions of this Exchange and Registration
Rights Agreement. If the Company shall so request, any such successor, assign or
transferee shall agree in writing to acquire and hold the Transfer Restricted
Securities subject to all of the applicable terms hereof.

warranties and each other provision set forth in this Exchange and Registration
Rights Agreement or made pursuant

hereto shall remain in full force and effect regardless of any investigation (or
statement as to the results thereof) made by or on behalf of any holder of
Transfer Restricted Securities, any director, officer or partner of such holder,
any agent or underwriter or any director, officer or partner thereof, or any
controlling person of any of the foregoing, and shall survive delivery of and
payment for the Transfer Restricted Securities pursuant to the Purchase
Agreement and the transfer and registration of Transfer Restricted Securities by
such holder and the consummation of an Exchange Offer.

     (f)  LAW GOVERNING.  THIS EXCHANGE AND REGISTRATION RIGHTS AGREEMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW
YORK.

Rights Agreement and shall not affect in any way the meaning or interpretation
of this Exchange and Registration Rights Agreement.

     (h)  Entire Agreement; Amendments.  This Exchange and Registration Rights
Agreement and the other writings referred to herein (including the Indenture and
the form of Securities) or delivered pursuant hereto which form a part hereof

matter.  This Exchange and Registration Rights Agreement supersedes all prior
agreements and understandings between the parties with respect to its subject
matter.  This Exchange and Registration Rights Agreement may be amended and the

waived (either generally or in a particular instance and either retroactively or
prospectively) only by a written instrument duly executed by the Company and the
holders of at least a majority in aggregate principal amount of the Transfer
Restricted Securities at the time outstanding.  Each holder of any Transfer
Restricted Securities at the time or thereafter outstanding shall be bound by
any amendment or waiver effected pursuant to this Section 9(h), whether or not
any notice, writing or marking indicating such amendment or waiver appears on
such Transfer Restricted Securities or is delivered to such holder.

     (i)  Counterparts.  This agreement may be executed by the parties in
counterparts, each of which shall be deemed to be an original, but all such
respective counterparts shall together constitute one and the same instrument.

   Subject to, and effective upon, the acceptance for exchange of all or any

tendered dollar-denominated Old Notes, 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 Old Notes to the Company together

   THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT THE UNDERSIGNED HAS
FULL POWER AND AUTHORITY TO TENDER, EXCHANGE, SELL, ASSIGN AND TRANSFER THE
OLD NOTES TENDERED HEREBY AND THAT, WHEN THE SAME ARE ACCEPTED FOR EXCHANGE,
THE COMPANY WILL ACQUIRE GOOD, MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE
AND CLEAR OF ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND THAT THE
OLD NOTES TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES.
THE UNDERSIGNED WILL, UPON REQUEST, EXECUTE AND DELIVER ANY ADDITIONAL
DOCUMENTS DEEMED BY THE COMPANY OR THE U.S. EXCHANGE AGENT TO BE NECESSARY OR
DESIRABLE TO COMPLETE THE EXCHANGE, ASSIGNMENT AND TRANSFER OF THE OLD NOTES
TENDERED HEREBY, AND THE UNDERSIGNED WILL COMPLY WITH ITS OBLIGATIONS UNDER

   Unless otherwise indicated herein in the box entitled "Special Exchange
Instructions" below (Box 7), the undersigned hereby directs that the New Notes
be issued in the name(s) of the undersigned or, in the case of a book-entry
transfer of Old Notes, that such New Notes be credited to the account

   THE EXCHANGE OFFER IS NOT BEING MADE TO ANY BROKER-DEALER WHO PURCHASED OLD
NOTES DIRECTLY FROM THE COMPANY FOR RESALE PURSUANT TO RULE 144A UNDER THE
SECURITIES ACT OR ANY PERSON THAT IS AN "AFFILIATE" OF THE COMPANY WITHIN THE
MEANING OF RULE 405 UNDER THE SECURITIES ACT. THE UNDERSIGNED UNDERSTANDS AND
AGREES THAT THE COMPANY RESERVES THE RIGHT NOT TO ACCEPT TENDERED OLD NOTES
FROM ANY TENDERING HOLDER IF THE COMPANY DETERMINES, IN ITS REASONABLE
DISCRETION, THAT SUCH ACCEPTANCE COULD RESULT IN A VIOLATION OF APPLICABLE
SECURITIES LAWS.

   BY TENDERING OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, THE
UNDERSIGNED HEREBY REPRESENTS AND AGREES THAT (i) THE UNDERSIGNED IS NOT AN
"AFFILIATE" OF THE COMPANY, (ii) ANY NEW NOTES TO BE RECEIVED BY THE

THE UNDERSIGNED HAS NO ARRANGEMENT OR UNDERSTANDING WITH ANY PERSON TO
PARTICIPATE IN A DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES ACT) OF
NEW NOTES TO BE RECEIVED IN THE EXCHANGE OFFER, AND (iv) IF THE UNDERSIGNED IS
NOT A BROKER-DEALER, THE UNDERSIGNED IS NOT ENGAGED IN, AND DOES NOT INTEND TO
ENGAGE IN, A DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES ACT) OF SUCH
NEW NOTES. BY TENDERING OLD NOTES PURSUANT TO THE EXCHANGE OFFER AND EXECUTING
THIS LETTER OF TRANSMITTAL, A HOLDER OF OLD NOTES WHICH IS A BROKER-DEALER
ADDITIONALLY REPRESENTS AND AGREES, CONSISTENT WITH CERTAIN INTERPRETIVE
LETTERS ISSUED BY THE STAFF OF THE DIVISION OF CORPORATION FINANCE OF THE
SECURITIES AND EXCHANGE COMMISSION TO THIRD PARTIES, THAT SUCH OLD NOTES WERE
ACQUIRED BY SUCH BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-
MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES (SUCH A BROKER-DEALER WHICH IS
TENDERING OLD NOTES IS HEREIN REFERRED TO AS A "PARTICIPATING BROKER-DEALER")
AND IT WILL DELIVER THE PROSPECTUS (AS AMENDED OR SUPPLEMENTED FROM TIME TO
TIME) MEETING THE REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY
RESALE OF SUCH NEW NOTES (PROVIDED THAT, BY SO ACKNOWLEDGING AND BY DELIVERING
A PROSPECTUS, SUCH PARTICIPATING BROKER-DEALER WILL NOT BE DEEMED TO ADMIT
THAT IT IS AN "UNDERWRITER" WITHIN THE MEANING OF THE SECURITIES ACT).

   THE COMPANY HAS AGREED THAT, SUBJECT TO THE PROVISIONS OF THE REGISTRATION
RIGHTS AGREEMENT, THE PROSPECTUS, AS IT MAY BE AMENDED OR SUPPLEMENTED FROM
TIME TO TIME, MAY BE USED BY A PARTICIPATING BROKER-DEALER IN CONNECTION WITH
RESALES OF NEW NOTES RECEIVED IN EXCHANGE FOR OLD NOTES, WHERE SUCH OLD NOTES
WERE ACQUIRED BY SUCH PARTICIPATING BROKER-DEALER FOR ITS OWN ACCOUNT AS A
RESULT OF MARKET-MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES, FOR A PERIOD
ENDING 180 DAYS AFTER THE EXCHANGE OFFER HAS BEEN COMPLETED, OR IF EARLIER,
WHEN ALL SUCH PARTICIPATING BROKER-DEALERS NO LONGER OWN ANY TRANSFER
RESTRICTED SECURITIES. IN THAT REGARD, EACH PARTICIPATING BROKER-DEALER, BY
TENDERING SUCH OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, AGREES TO
NOTIFY THE COMPANY PRIOR TO USING THE PROSPECTUS IN CONNECTION WITH THE SALE
OF TRANSFER OF NEW NOTES AND ACKNOWLEDGES AND AGREES THAT, UPON RECEIPT OF
NOTICE FROM THE COMPANY OF THE OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY
FACT WHICH MAKES ANY STATEMENT CONTAINED OR INCORPORATED BY REFERENCE IN THE
PROSPECTUS UNTRUE IN ANY MATERIAL RESPECT OR WHICH CAUSES THE PROSPECTUS TO
OMIT TO STATE A MATERIAL FACT NECESSARY IN ORDER TO MAKE THE STATEMENTS
CONTAINED THEREIN, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH THEY WERE MADE,
NOT MISLEADING OR OF THE OCCURRENCE OF

                                                                              3
<PAGE>

CERTAIN OTHER EVENTS SPECIFIED IN THE REGISTRATION RIGHTS AGREEMENT, SUCH
PARTICIPATING BROKER-DEALER WILL SUSPEND THE SALE OF NEW NOTES PURSUANT TO THE
PROSPECTUS UNTIL THE COMPANY HAS AMENDED OR SUPPLEMENTED THE PROSPECTUS TO
CORRECT SUCH MISSTATEMENT OR OMISSION AND HAS FURNISHED COPIES OF THE AMENDED
OR SUPPLEMENTED PROSPECTUS TO THE PARTICIPATING BROKER-DEALER OR THE COMPANY
HAS GIVEN NOTICE THAT THE SALE OF THE NEW NOTES MAY BE RESUMED, AS THE CASE
MAY BE.

   EACH PARTICIPATING BROKER-DEALER SHOULD CHECK THE BOX HEREIN UNDER THE
CAPTION "PARTICIPATING BROKER-DEALER" (BOX 5 HEREOF) IN ORDER TO RECEIVE
ADDITIONAL COPIES OF THE PROSPECTUS, AND ANY AMENDMENTS AND SUPPLEMENTS
THERETO, FOR USE IN CONNECTION WITH RESALES OF THE NEW NOTES, AS WELL AS ANY
NOTICES FROM THE COMPANY TO SUSPEND AND RESUME USE OF THE PROSPECTUS. BY
TENDERING ITS OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, EACH
PARTICIPATING BROKER-DEALER AGREES TO USE ITS REASONABLE BEST EFFORTS TO
NOTIFY THE COMPANY OR THE U.S. EXCHANGE AGENT WHEN IT HAS SOLD ALL OF ITS NEW
NOTES. IF NO PARTICIPATING BROKER-DEALERS CHECK SUCH BOX, OR IF ALL
PARTICIPATING BROKER-DEALERS WHO HAVE CHECKED SUCH BOX SUBSEQUENTLY NOTIFY THE
COMPANY OR THE U.S. EXCHANGE AGENT THAT ALL THEIR NEW NOTES HAVE BEEN SOLD,
THE COMPANY WILL NOT BE REQUIRED TO MAINTAIN THE EFFECTIVENESS OF THE EXCHANGE
OFFER REGISTRATION STATEMENT OR TO UPDATE THE PROSPECTUS AND WILL NOT PROVIDE
ANY HOLDERS WITH ANY NOTICE TO SUSPEND OR RESUME USE OF THE PROSPECTUS.

   Each New note will bear interest from the most recent date to which
interest has been paid or duly provided for on the Old Note surrendered in
exchange for such New Note or, if no such interest has been paid or duly
provided for on such Old Note, from December 8, 1999, the date of issuance of
the Old Notes. Holders of the Old Notes whose Old Notes are accepted for
exchange will not receive accrued interest on such Old Notes for any period
from and after the last Interest Payment Date to which interest has been paid
or duly provided for on such Old Notes prior to the original issue date of the
New Notes or, if no such interest has been paid or duly provided for, will not
receive any accrued interest on such Old Notes, and will be deemed to have
waived the right to receive any interest on such Old Notes accrued from and
after such Interest Payment Date or, if no such interest has been paid or duly
provided for, from and after December 8, 1999.

   The undersigned understands that the delivery and surrender of the Old
Notes is not effective, and the risk of loss of the Old Notes does not pass to
the U.S. Exchange Agent, until receipt by the U.S. Exchange Agent of this
Letter of Transmittal, or a manually signed facsimile hereof, properly
completed and duly executed, with any required signature guarantees, together
with all accompanying evidences of authority and any other required documents
in form satisfactory to the Company. All questions as to form of all documents
and the validity (including time or receipt) and acceptance of tenders and
withdrawals of Old Notes will be determined by the Company, in its sole
discretion, which determination shall be final and binding.

   All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall survive the death or incapacity of the undersigned and any
obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, personal representatives, trustees in bankruptcy,
legal representatives, successors and assigns of the undersigned. Except
pursuant to the withdrawal rights set forth in the Prospectus, this tender is
irrevocable.

   PLEASE READ THIS ENTIRE LETTER OF TRANSMITTAL CAREFULLY BEFORE COMPLETING
THE BOXES BELOW AND FOLLOW THE INSTRUCTIONS BEGINNING ON PAGE 9 HEREOF.

   THE EXCHANGE OFFER IS NOT BEING MADE TO (NOR WILL TENDERS OF OLD NOTES BE
ACCEPTED FROM OR ON BEHALF OF) HOLDERS IN ANY JURISDICTION IN WHICH THE MAKING
OR ACCEPTANCE OF THE EXCHANGE OFFER WOULD NOT BE IN COMPLIANCE WITH THE LAWS
OF SUCH JURISDICTION.

Transmittal and any required supporting documents should be mailed in the
enclosed addressed envelope, or otherwise delivered, to the U.S. Exchange
Agent, at either of the addresses indicated on the first page hereof. THE
METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER AND
THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE U.S.
EXCHANGE AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
   PROCEDURES

   This Letter of Transmittal is to be completed if either (a) Certificates
are to be forwarded herewith or (b) tenders are to be made pursuant to the
procedures for tender by book-entry transfer set forth in "The Exchange
Offer--Procedures for Tendering Old Notes" in the Prospectus. Certificates, or
timely confirmation of a book-entry transfer of such Old Notes into the U.S.
Exchange Agent's account at DTC, as well as this Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and any other documents required by this Letter of
Transmittal, must be received by the U.S. Exchange Agent at its address set

of Transmittal and all other required documents to the U.S. Exchange Agent on
or prior to the Expiration Date or (iii) who cannot complete the procedures
for delivery by book-entry transfer on a timely basis,

                                                                              9

such tender must be made by or through an Eligible Institution (as defined
below); (ii) a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form made available by the Company, must be

completed and duly executed, with any required signature guarantees and any
other documents required by this Letter of Transmittal, must be received by
the U.S. Exchange Agent within three New York Stock Exchange trading days

by facsimile or mail to the U.S. Exchange Agent, and must include a guarantee
by an Eligible Institution in the form set forth in such Notice. For Old Notes
to be properly tendered pursuant to the guaranteed delivery procedure, the
U.S. Exchange Agent must receive a Notice of Guaranteed Delivery on or prior
to the Expiration Date. As used herein, "Eligible Institution" means a firm or
other entity identified in Rule 17Ad-15 under the Exchange Act as "an eligible
guarantor institution," including (as such terms are defined therein) (i) a
bank; (ii) a broker, dealer, municipal securities broker or dealer or
government securities broker or dealer; (iii) a credit union; (iv) a national
securities exchange, registered securities association or clearing agency; or
(v) a savings association, that is a participant in the Securities Transfer
Agents Medallion Program, the New York Stock Exchange Medallion Signature
Program or the Stock Exchange Medallion Program.

   The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance
of such tender.

2. GUARANTEE OF SIGNATURES

   No signature guarantee on this Letter of Transmittal is required if:

     (i) this Letter of Transmittal is signed by the registered holder (which
  term, for purposes of this document, shall include any participant in DTC
  whose name appears on a security position listing as the owner of the Old
  Notes) of Old Notes tendered herewith, unless such holder(s) has completed
  either the box entitled "Special Exchange Instructions" (Box 7) or the box
  entitled "Special Delivery Instructions" (Box 8) above, or

     (ii) such Old Notes are tendered for the account of a firm that is an
  Eligible Institution.

   In all other cases, an Eligible Institution must guarantee the signature(s)
on this Letter of Transmittal (Box 6). See Instruction 5.

3. INADEQUATE SPACE

   If the space provided in the box captioned "Description of Old Notes" is
inadequate, the Certificate number(s) and/or the principal amount of Old Notes
and any other required information should be listed on a separate signed
schedule which should be attached to this Letter of Transmittal.

4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS

   Tenders of Old Notes will be accepted only in the principal amount of
$1,000 and integral multiples thereof. If less than all the Old Notes
evidenced by any Certificate submitted are to be tendered, fill in the
principal amount of Old Notes which are to be tendered in Box 1 under the
column "Principal Amount of Old Notes Tendered". In such case, new
Certificate(s) for the remainder of the Old Notes that were evidenced by your
Old Notes Certificate(s) will only be sent to the holder of the Old Notes,
promptly after the Expiration Date. All Old Notes represented by Certificates
delivered to the U.S. Exchange Agent will be deemed to have been tendered
unless otherwise indicated.

   Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time on or prior to the Expiration Date. In order for a withdrawal to
be effective on or prior to that time, a written, telegraphic, telex or
facsimile transmission

10
<PAGE>

of such notice of withdrawal must be timely received by the U.S. Exchange
Agent at its address set forth above or in the Prospectus on or prior to the
Expiration Date. Any such notice of withdrawal must specify the name of the
person who tendered the Old Notes to be withdrawn, the aggregate principal
amount of Old Notes to be withdrawn, and (if Certificates for such Old Notes
have been tendered) the name of the registered holder of the Old Notes as set
forth on the Certificate for the Old Notes, if different from that of the
person who tendered such Old Notes. If Certificates for the Old Notes have
been delivered or otherwise identified to the U.S. Exchange Agent, then prior
to the physical release of such Certificates for the Old Notes, the tendering
holder must submit the serial numbers shown on the particular Certificates for
the Old Notes to be withdrawn and the signature on the notice of withdrawal
must be guaranteed by an Eligible Institution, except in the case of Old Notes
tendered for the account of an Eligible Institution. If Old Notes have been
tendered pursuant to the procedures for book-entry transfer set forth in "The
Exchange Offer--Procedures for Tendering Old Notes," the notice of withdrawal
must specify the name and number of the account at DTC to be credited with the
withdrawal of Old Notes, in which case a notice of withdrawal will be
effective if delivered to the U.S. Exchange Agent by written, telegraphic,
telex or facsimile transmission. Withdrawals of tenders of Old Notes may not
be rescinded. Old Notes properly withdrawn will not be deemed validly tendered
for purposes of the U.S. Exchange Offer, but may be retendered at any
subsequent time on or prior to the Expiration Date by following any of the
procedures described in the Prospectus under "The Exchange Offer--Procedures
for Tendering Old Notes."

   All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all
parties. Neither the Company, any affiliates or assigns of the Company, the
U.S. Exchange Agent nor any other person shall be under any duty to give any
notification of any irregularities in any notice of withdrawal or incur any
liability for failure to give such notification. Any Old Notes which have been
tendered but which are withdrawn will be returned to the holder thereof
without cost to such holder promptly after withdrawal.

5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS

   If this Letter of Transmittal is signed by the registered holder(s) of the
Old Notes tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the Certificate(s) without alteration,
enlargement or any change whatsoever.

   If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

   If any tendered Old Notes are registered in different name(s) on several
Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.

   If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing and, unless waived by the
Company, must submit proper evidence satisfactory to the Company, in its sole
discretion, of such persons' authority to so act.

   When this Letter of Transmittal is signed by the registered owner(s) of the
Old Notes listed and transmitted hereby, no endorsement(s) of Certificate(s)
or separate bond power(s) are required unless New Notes are to be issued in
the name of a person other than the registered holder(s). However, if New
Notes are to be issued in the name of a person other than the registered
holder(s), signature(s) on such Certificate(s) or bond power(s) must be
guaranteed by an Eligible Institution.

   If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Old Notes listed, the certificates must be endorsed
or accompanied by appropriate bond powers, signed exactly as the name or names
of the registered owner(s) appear(s) on the Certificates, and also must be
accompanied by such opinions of counsel, certifications and other information
as the Company or the Trustee for the Old Notes may require in accordance with
the restrictions on transfer applicable to the Old Notes. Signatures on such
Certificates or bond powers must be guaranteed by an Eligible Institution.

                                                                             11
<PAGE>

6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS

   If New Notes are to be issued in the name of a person other than the signer
of this Letter of Transmittal, or if New Notes are to be sent to someone other
than the signer of this Letter of Transmittal or to an address other than that
shown above, the appropriate boxes on this Letter of Transmittal should be
completed (Box 7 and 8). Certificates for Old Notes not exchanged will be
returned by mail or, if tendered by book-entry transfer, by crediting the
account indicated above maintained at DTC. See Instruction 4.

7. DETERMINATION OF VALIDITY

   The Company will determine, in its sole discretion, all questions as to the
form of documents, validity, eligibility (including time of receipt) and
acceptance for exchange of any tender of Old Notes, which determination shall
be final and binding on all parties. The Company reserves the absolute right
to reject any and all tenders determined by it not to be in proper form or the
acceptance of which, or exchange for, may, in the view of counsel to the
Company, be unlawful. The Company also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "The Exchange Offer--Conditions to the Exchange Offer"
or any conditions or irregularity in any tender of Old Notes of any particular
holder whether or not similar conditions or irregularities are waived in the
case of other holders.

   The Company's interpretation of the terms and conditions of the Exchange
Offer (including this Letter of Transmittal and the instructions hereto) will
be final and binding. No tender of Old Notes will be deemed to have been
validly made until all irregularities with respect to such tender have been
cured or waived. Neither the Company, any affiliates or assigns of the
Company, the U.S. Exchange Agent, nor any other person shall be under any duty
to give notification of any irregularities in tenders or incur any liability
for failure to give such notification.

8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES

   Questions and requests for assistance may be directed to the U.S. Exchange
Agent at its address and telephone number set forth on the front of this
Letter of Transmittal. Additional copies of the Prospectus, the Notice of
Guaranteed Delivery and the Letter of Transmittal may be obtained from the
U.S. Exchange Agent.

9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9

   For U.S. Federal income tax purposes, holders are required, unless an
exemption applies, to provide the U.S. Exchange Agent with such holder's
correct taxpayer identification number ("TIN") on Substitute Form W-9 of this
Letter of Transmittal (Box 9) and certify, under penalties of perjury, that
such number is correct and he or she is not subject to backup withholding. If
the U.S. Exchange Agent is not provided with the correct TIN, the Internal
Revenue Service (the "IRS") may subject the holder or other payee to a $50
penalty. In addition, payments to such holders or other payees with respect to
Old Notes exchanged pursuant to the Exchange Offer, or with respect to New
Notes following the Exchange Offer, may be subject to 31% backup withholding.

   The box in Part 2 of the Substitute Form W-9 (Box 9) may be checked if the
tendering holder 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 2 is
checked, the holder or other payee must also complete the Certificate of
Awaiting Taxpayer Identification Number below Substitute Form W-9 in order to
avoid backup withholding. Notwithstanding that the box in Part 2 is checked
and the Certificate of Awaiting Taxpayer Identification Number is completed,
the U.S. Exchange Agent will withhold 31% of all payments made prior to the
time a properly certified TIN is provided to the U.S. Exchange Agent.

   The holder is required to give the U.S. Exchange Agent the TIN (i.e.,
social security number or employer identification number) of the registered
owner of the Old Notes or of the last transferee appearing on the transfers
attached to, or endorsed on, the Old Notes. If the Old Notes are registered in
more than one name or are not in the name of the actual owner, consult the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional guidance on which number to report.

12
<PAGE>

   Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below and check the box in Part 3 of
Box 9 for "exempt", to avoid possible erroneous backup withholding. A foreign
person may qualify as an exempt recipient by submitting a properly completed
IRS Form W-8, signed under penalties of perjury, attesting to that holder's
exempt status. Please consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which holders are exempt from backup withholding.

   Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. Federal income tax liability of a person 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.

10. LOST, DESTROYED OR STOLEN CERTIFICATES

   If any Certificate(s) representing Old Notes have been lost, destroyed or
stolen, the holder should promptly notify the U.S. Exchange Agent. The holder
will then be instructed as to the steps that must be taken in order to replace
the Certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, destroyed or stolen

11. SECURITY TRANSFER TAXES

   Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith. If, however, New Notes are to
be delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered, or if a transfer tax is imposed
for any reason other than the exchange of Old Notes in connection with the
Exchange Offer, then the amount of any such transfer tax (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.

   IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF) AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE U.S. EXCHANGE AGENT ON OR PRIOR TO
THE EXPIRATION DATE.

   B. EXEMPT PAYEES--The following lists exempt payees. If you are exempt, you
must nonetheless complete the form and provide your TIN in order to establish
that you are exempt. Check the box in Part 3 of the form, sign and date
the form.

   For this purpose, Exempt Payees include: (1) A corporation; (2) An
organization exempt from tax under section 501(a), or an individual retirement
plan (IRA) or a custodial account under section 403(b)(7); (3) The United
States or any of its agencies or instrumentalities; (4) A state, the District
of Columbia, a possession of the United States, or any of their political
subdivisions or instrumentalities; (5) A foreign government or any of its
political subdivisions, agencies or instrumentalities; (6) An international

   C. OBTAINING A NUMBER--If you do not have a taxpayer identification number
or you do not know your number, obtain Form SS-5, application for a Social
Security Number, or Form SS-4, Application for Employer Identification Number,
at the local office of the Social Security Administration or the Internal
Revenue Service and apply for a number.

   D. PRIVACY ACT NOTICE--Section 6109 requires most recipients of dividend,
interest or other payments to give taxpayer identification numbers to payers
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payers must be given the numbers whether or not
payees are required to file tax returns. Payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
furnish a taxpayer identification number. Certain penalties may also apply.

E. PENALTIES

    (1) Penalty for Failure to Furnish Taxpayer Identification Number. If you
fail to furnish your taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.

    (2) Failure to Report Certain Dividend and Interest Payments. If you fail
to include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and
convincing evidence to the contrary.

    (3) Civil Penalty for False Information with Respect to Withholding. If
you make a false statement with no reasonable basis which results in no
imposition of backup withholding, you are subject to a penalty of $500.

    (4) Criminal Penalty for Falsifying Information. Falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.

   FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.

Ladies and Gentlemen:

   The undersigned hereby tenders to Exodus Communications, Inc., a Delaware
corporation (the "Company"), the aggregate principal amount of the Company's
euro-denominated 10 3/4% Senior Notes due 2009 (the "Old Notes") described in
Box 1 below, in exchange for a like aggregate principal amount of the
Company's new euro-denominated 10 3/4% Senior Notes due 2009 (the "New Notes")
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       , 2000 (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, constitutes
the "Exchange Offer").

   Subject to, and effective upon, the acceptance for exchange of all or any
portion of the Old Notes 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 sells, assigns and transfers to or upon the order of the
Company all right, title and interest in and to such Old Notes as are being
tendered herewith. The undersigned hereby irrevocably constitutes and appoints
Chase Manhattan Bank London as the Euro Exchange Agent (the "Euro Exchange
Agent") as its agent and attorney-in-fact (with full knowledge that the Euro
Exchange Agent is also acting as agent of the Company in connection with the
Exchange Offer) with respect to the tendered euro-denominated Old Notes, 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 Old
Notes to the Company together with all accompanying evidences of transfer and
authenticity to, or upon the order of, the Company, upon receipt by the Euro
Exchange Agent, as the undersigned's agent, of the New Notes to be issued in
exchange for such Old Notes, (ii) present Certificates for such Old Notes for
transfer, and to transfer the Old Notes on the books of the Company, and
(iii) receive for the account of the Company all benefits and otherwise
exercise all rights of beneficial ownership of such Old Notes, all in
accordance with the terms and conditions of the Exchange Offer.

   THE UNDERSIGNED HEREBY REPRESENTS AND WARRANTS THAT THE UNDERSIGNED HAS
FULL POWER AND AUTHORITY TO TENDER, EXCHANGE, SELL, ASSIGN AND TRANSFER THE
OLD NOTES TENDERED HEREBY AND THAT, WHEN THE SAME ARE ACCEPTED FOR EXCHANGE,
THE COMPANY WILL ACQUIRE GOOD, MARKETABLE AND UNENCUMBERED TITLE THERETO, FREE
AND CLEAR OF ALL LIENS, RESTRICTIONS, CHARGES AND ENCUMBRANCES, AND THAT THE
OLD NOTES TENDERED HEREBY ARE NOT SUBJECT TO ANY ADVERSE CLAIMS OR PROXIES.
THE UNDERSIGNED WILL, UPON REQUEST, EXECUTE AND DELIVER ANY ADDITIONAL
DOCUMENTS DEEMED BY THE COMPANY OR THE EURO EXCHANGE AGENT TO BE NECESSARY OR
DESIRABLE TO COMPLETE THE EXCHANGE, ASSIGNMENT AND TRANSFER OF THE OLD NOTES
TENDERED HEREBY, AND THE UNDERSIGNED WILL COMPLY WITH ITS OBLIGATIONS UNDER
THE REGISTRATION RIGHTS AGREEMENT. THE UNDERSIGNED HAS READ AND AGREES TO ALL
OF THE TERMS OF THE EXCHANGE OFFER.

   The name(s) and address(es) of the registered holder(s) of the Old Notes
tendered hereby should be printed in Box 1 below, if they are not already set
forth below, as they appear on the Certificates representing such Old Notes.
The Certificate number(s) and the Old Notes that the undersigned wishes to
tender should be indicated in the appropriate box below.

   If any tendered Old Notes are not exchanged pursuant to the Exchange Offer
for any reason, or if Certificates are submitted for more Old Notes than are
tendered or accepted for exchange, Certificates for such nonexchanged or
nontendered Old Notes will be returned (or, in the case of Old Notes tendered
by book-entry transfer, such Old Notes will be credited to an account
maintained at Euroclear or Cedelbank, as applicable), without expense to the
tendering holder, promptly following the expiration or termination of the
Exchange Offer.

   The undersigned understands that tenders of Old Notes pursuant to any one
of the procedures described in "The Exchange Offer--Procedures for Tendering
Old Notes" in the Prospectus and in the instructions hereto will, upon the
Company's acceptance for exchange of such tendered Old Notes, constitute a
binding agreement between the undersigned and the Company upon the terms and

not be required to accept for exchange any of the Old Notes tendered hereby.

   Unless otherwise indicated herein in the box entitled "Special Exchange
Instructions" below (Box 7), the undersigned hereby directs that the New Notes
be issued in the name(s) of the undersigned or, in the case of a book-entry
transfer of Old Notes, that such New Notes be credited to the account
indicated below maintained at Euroclear or Cedelbank, as applicable. If
applicable, substitute Certificates representing Old Notes not exchanged or
not accepted for exchange will be issued to the undersigned or, in the case of
a book-entry transfer of Old Notes, will be credited to the account indicated
below maintained at Euroclear or Cedelbank, as applicable. Similarly, unless
otherwise indicated under "Special Delivery Instructions" (Box 8), please
deliver New Notes to the undersigned at the address shown below the

   THE EXCHANGE OFFER IS NOT BEING MADE TO ANY BROKER-DEALER WHO PURCHASED OLD
NOTES DIRECTLY FROM THE COMPANY FOR RESALE PURSUANT TO RULE 144A UNDER THE
SECURITIES ACT OR ANY PERSON THAT IS AN "AFFILIATE" OF THE COMPANY WITHIN THE
MEANING OF RULE 405 UNDER THE SECURITIES ACT. THE UNDERSIGNED UNDERSTANDS AND
AGREES THAT THE COMPANY RESERVES THE RIGHT NOT TO ACCEPT TENDERED OLD NOTES
FROM ANY TENDERING HOLDER IF THE COMPANY DETERMINES, IN ITS REASONABLE
DISCRETION, THAT SUCH ACCEPTANCE COULD RESULT IN A VIOLATION OF APPLICABLE
SECURITIES LAWS.

   BY TENDERING OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, THE
UNDERSIGNED HEREBY REPRESENTS AND AGREES THAT (i) THE UNDERSIGNED IS NOT AN
"AFFILIATE" OF THE COMPANY, (ii) ANY NEW NOTES TO BE RECEIVED BY THE
UNDERSIGNED ARE BEING ACQUIRED IN THE ORDINARY COURSE OF ITS BUSINESS, (iii)
THE UNDERSIGNED HAS NO ARRANGEMENT OR UNDERSTANDING WITH ANY PERSON TO
PARTICIPATE IN A DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES ACT) OF
NEW NOTES TO BE RECEIVED IN THE EXCHANGE OFFER, AND (iv) IF THE UNDERSIGNED IS
NOT A BROKER-DEALER, THE UNDERSIGNED IS NOT ENGAGED IN, AND DOES NOT INTEND TO
ENGAGE IN, A DISTRIBUTION (WITHIN THE MEANING OF THE SECURITIES ACT) OF SUCH
NEW NOTES. BY TENDERING OLD NOTES PURSUANT TO THE EXCHANGE OFFER AND EXECUTING
THIS LETTER OF TRANSMITTAL, A HOLDER OF OLD NOTES WHICH IS A BROKER-DEALER
ADDITIONALLY REPRESENTS AND AGREES, CONSISTENT WITH CERTAIN INTERPRETIVE
LETTERS ISSUED BY THE STAFF OF THE DIVISION OF CORPORATION FINANCE OF THE
SECURITIES AND EXCHANGE COMMISSION TO THIRD PARTIES, THAT SUCH OLD NOTES WERE
ACQUIRED BY SUCH BROKER-DEALER FOR ITS OWN ACCOUNT AS A RESULT OF MARKET-
MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES (SUCH A BROKER-DEALER WHICH IS
TENDERING OLD NOTES IS HEREIN REFERRED TO AS A "PARTICIPATING BROKER-DEALER")
AND IT WILL DELIVER THE PROSPECTUS (AS AMENDED OR SUPPLEMENTED FROM TIME TO
TIME) MEETING THE REQUIREMENTS OF THE SECURITIES ACT IN CONNECTION WITH ANY
RESALE OF SUCH NEW NOTES (PROVIDED THAT, BY SO ACKNOWLEDGING AND BY DELIVERING
A PROSPECTUS, SUCH PARTICIPATING BROKER-DEALER WILL NOT BE DEEMED TO ADMIT
THAT IT IS AN "UNDERWRITER" WITHIN THE MEANING OF THE SECURITIES ACT).

   THE COMPANY HAS AGREED THAT, SUBJECT TO THE PROVISIONS OF THE REGISTRATION
RIGHTS AGREEMENT, THE PROSPECTUS, AS IT MAY BE AMENDED OR SUPPLEMENTED FROM
TIME TO TIME, MAY BE USED BY A PARTICIPATING BROKER-DEALER IN CONNECTION WITH
RESALES OF NEW NOTES RECEIVED IN EXCHANGE FOR OLD NOTES, WHERE SUCH OLD NOTES
WERE ACQUIRED BY SUCH PARTICIPATING BROKER-DEALER FOR ITS OWN ACCOUNT AS A
RESULT OF MARKET-MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES, FOR A PERIOD
ENDING 180 DAYS AFTER THE EXCHANGE OFFER HAS BEEN COMPLETED, OR IF EARLIER,
WHEN ALL SUCH PARTICIPATING BROKER-DEALERS NO LONGER OWN ANY TRANSFER
RESTRICTED SECURITIES. IN THAT REGARD, EACH PARTICIPATING BROKER-DEALER, BY
TENDERING SUCH OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, AGREES TO
NOTIFY THE COMPANY PRIOR TO USING THE PROSPECTUS IN CONNECTION WITH THE SALE
OR TRANSFER OF NEW NOTES AND ACKNOWLEDGES AND AGREES THAT, UPON RECEIPT OF
NOTICE FROM THE COMPANY OF THE OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY
FACT WHICH MAKES ANY STATEMENT CONTAINED OR INCORPORATED BY REFERENCE IN THE
PROSPECTUS UNTRUE IN ANY MATERIAL RESPECT OR WHICH CAUSES THE PROSPECTUS TO
OMIT TO STATE A MATERIAL FACT NECESSARY IN ORDER TO MAKE THE STATEMENTS
CONTAINED THEREIN, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH THEY WERE MADE,
NOT MISLEADING OR OF THE OCCURRENCE OF

                                                                              3
<PAGE>

CERTAIN OTHER EVENTS SPECIFIED IN THE REGISTRATION RIGHTS AGREEMENT, SUCH
PARTICIPATING BROKER- DEALER WILL SUSPEND THE SALE OF NEW NOTES PURSUANT TO
THE PROSPECTUS UNTIL THE COMPANY HAS AMENDED OR SUPPLEMENTED THE PROSPECTUS TO
CORRECT SUCH MISSTATEMENT OR OMISSION AND HAS FURNISHED COPIES OF THE AMENDED
OR SUPPLEMENTED PROSPECTUS TO THE PARTICIPATING BROKER-DEALER OR THE COMPANY
HAS GIVEN NOTICE THAT THE SALE OF THE NEW NOTES MAY BE RESUMED, AS THE CASE
MAY BE.

   EACH PARTICIPATING BROKER-DEALER SHOULD CHECK THE BOX HEREIN UNDER THE
CAPTION "PARTICIPATING BROKER-DEALER" (BOX 5 HEREOF) IN ORDER TO RECEIVE
ADDITIONAL COPIES OF THE PROSPECTUS, AND ANY AMENDMENTS AND SUPPLEMENTS
THERETO, FOR USE IN CONNECTION WITH RESALES OF THE NEW NOTES, AS WELL AS ANY
NOTICES FROM THE COMPANY TO SUSPEND AND RESUME USE OF THE PROSPECTUS. BY
TENDERING ITS OLD NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, EACH
PARTICIPATING BROKER-DEALER AGREES TO USE ITS REASONABLE BEST EFFORTS TO
NOTIFY THE COMPANY OR THE EURO EXCHANGE AGENT WHEN IT HAS SOLD ALL OF ITS NEW
NOTES. IF NO PARTICIPATING BROKER-DEALERS CHECK SUCH BOX, OR IF ALL
PARTICIPATING BROKER-DEALERS WHO HAVE CHECKED SUCH BOX SUBSEQUENTLY NOTIFY THE
COMPANY OR THE EURO EXCHANGE AGENT THAT ALL THEIR NEW NOTES HAVE BEEN SOLD,
THE COMPANY WILL NOT BE REQUIRED TO MAINTAIN THE EFFECTIVENESS OF THE EXCHANGE
OFFER REGISTRATION STATEMENT OR TO UPDATE THE PROSPECTUS AND WILL NOT PROVIDE
ANY HOLDERS WITH ANY NOTICES TO SUSPEND OR RESUME USE OF THE PROSPECTUS.

   Each New note will bear interest from the most recent date to which
interest has been paid or duly provided for on the Old Note surrendered in
exchange for such New Note or, if no such interest has been paid or duly
provided for on such Old Note, from December 8, 1999, the date of issuance of
the Old Notes. Holders of the Old Notes whose Old Notes are accepted for
exchange will not receive accrued interest on such Old Notes for any period
from and after the last Interest Payment Date to which interest has been paid
or duly provided for on such Old Notes prior to the original issue date of the
New Notes or, if no such interest has been paid or duly provided for, will not
receive any accrued interest on such Old Notes, and will be deemed to have
waived the right to receive any interest on such Old Notes accrued from and
after such Interest Payment Date or, if no such interest has been paid or duly
provided for, from and after December 8, 1999.

   The undersigned understands that the delivery and surrender of the Old
Notes is not effective, and the risk of loss of the Old Notes does not pass to
the Euro Exchange Agent, until receipt by the Euro Exchange Agent of this
Letter of Transmittal, or a manually signed facsimile hereof, properly
completed and duly executed, with any required signature guarantees, together
with all accompanying evidences of authority and any other required documents
in form satisfactory to the Company. All questions as to form of all documents
and the validity (including time of receipt) and acceptance of tenders and
withdrawals of Old Notes will be determined by the Company, in its sole
discretion, which determination shall be final and binding.

   All authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall survive the death or incapacity of the undersigned and any
obligation of the undersigned hereunder shall be binding upon the heirs,
executors, administrators, personal representatives, trustees in bankruptcy,
legal representatives, successors and assigns of the undersigned. Except
pursuant to the withdrawal rights set forth in the Prospectus, this tender is
irrevocable.

   PLEASE READ THIS ENTIRE LETTER OF TRANSMITTAL CAREFULLY BEFORE COMPLETING
THE BOXES BELOW AND FOLLOW THE INSTRUCTIONS BEGINNING ON PAGE 9 HEREOF.

   THE EXCHANGE OFFER IS NOT BEING MADE TO (NOR WILL TENDERS OF OLD NOTES BE
ACCEPTED FROM OR ON BEHALF OF) HOLDERS IN ANY JURISDICTION IN WHICH THE MAKING
OR ACCEPTANCE OF THE EXCHANGE OFFER WOULD NOT BE IN COMPLIANCE WITH THE LAWS
OF SUCH JURISDICTION.

Agent, at either of the addresses indicated on the first page hereof. THE
METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL OTHER

   This Letter of Transmittal is to be completed if either (a) Certificates
are to be forwarded herewith or (b) tenders are to be made pursuant to the
procedures for tender by book-entry transfer set forth in "The Exchange
Offer--Procedures for Tendering Old Notes" in the Prospectus. Certificates, or

tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance
of such tender.

2. GUARANTEE OF SIGNATURES

   No signature guarantee on this Letter of Transmittal is required if:

     (i) this Letter of Transmittal is signed by the registered holder (which
  term, for purposes of this document, shall include any participant in

  the owner of the Old Notes) of Old Notes tendered herewith, unless such
  holder(s) has completed either the box entitled "Special Exchange
  Instructions" (Box 7) or the box entitled "Special Delivery Instructions"
  (Box 8) above, or

     (ii) such Old Notes are tendered for the account of a firm that is an

schedule which should be attached to this Letter of Transmittal.

4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS

   Tenders of Old Notes will be accepted only in the principal amount of Euro
1,000 and integral multiples thereof. If less than all the Old Notes evidenced
by any Certificate submitted are to be tendered, fill in the principal amount
of Old Notes which are to be tendered in Box 1 under the column "Principal
Amount of Old Notes Tendered". In such case, new Certificate(s) for the
remainder of the Old Notes that were evidenced by your Old Notes
Certificate(s) will only be sent to the holder of the Old Notes, promptly
after the Expiration Date. All Old Notes represented by Certificates delivered
to the Euro Exchange Agent will be deemed to have been tendered unless
otherwise indicated.

10
<PAGE>

   Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time on or prior to the Expiration Date. In order for a withdrawal to
be effective on or prior to that time, a written, telegraphic, telex or
facsimile transmission of such notice of withdrawal must be timely received by
the Euro Exchange Agent at its address set forth above or in the Prospectus on
or prior to the Expiration Date. Any such notice of withdrawal must specify
the name of the person who tendered the Old Notes to be withdrawn, the
aggregate principal amount of Old Notes to be withdrawn, and (if Certificates
for such Old Notes have been tendered) the name of the registered holder of
the Old Notes as set forth on the Certificate for the Old Notes, if different
from that of the person who tendered such Old Notes. If Certificates for the
Old Notes have been delivered or otherwise identified to the Euro Exchange
Agent, then prior to the physical release of such Certificates for the Old
Notes, the tendering holder must submit the serial numbers shown on the
particular Certificates for the Old Notes to be withdrawn and the signature on
the notice of withdrawal must be guaranteed by an Eligible Institution, except
in the case of Old Notes tendered for the account of an Eligible Institution.
If Old Notes have been tendered pursuant to the procedures for book-entry
transfer set forth in "The Exchange Offer--Procedures for Tendering Old
Notes," the notice of withdrawal must specify the name and number of the
account at Euroclear or Cedelbank, as applicable, to be credited with the
withdrawal of Old Notes, in which case a notice of withdrawal will be
effective if delivered to the Euro Exchange Agent by written, telegraphic,
telex or facsimile transmission. Withdrawals of tenders of Old Notes may not
be rescinded. Old Notes properly withdrawn will not be deemed validly tendered
for purposes of the Exchange Offer, but may be retendered at any subsequent
time on or prior to the Expiration Date by following any of the procedures
described in the Prospectus under "The Exchange Offer--Procedures for
Tendering Old Notes."

   All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all
parties. Neither the Company, any affiliates or assigns of the Company, the
Euro Exchange Agent nor any other person shall be under any duty to give any
notification of any irregularities in any notice of withdrawal or incur any
liability for failure to give such notification. Any Old Notes which have been
tendered but which are withdrawn will be returned to the holder thereof
without cost to such holder promptly after withdrawal.

5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS

   If this Letter of Transmittal is signed by the registered holder(s) of the
Old Notes tendered hereby, the signature(s) must correspond exactly with the
name(s) as written on the face of the Certificate(s) without alteration,
enlargement or any change whatsoever.

   If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

   If any tendered Old Notes are registered in different name(s) on several
Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.

   If this Letter of Transmittal or any Certificates or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing and, unless waived by the
Company, must submit proper evidence satisfactory to the Company, in its sole
discretion, of such persons' authority to so act.

   When this Letter of Transmittal is signed by the registered owner(s) of the
Old Notes listed and transmitted hereby, no endorsement(s) of Certificate(s)
or separate bond power(s) are required unless New Notes are to be issued in
the name of a person other than the registered holder(s). However, if New
Notes are to be issued in the name of a person other than the registered
holder(s), signature(s) on such Certificate(s) or bond power(s) must be
guaranteed by an Eligible Institution.

   If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Old Notes listed, the certificates must be endorsed
or accompanied by appropriate bond powers, signed exactly as the name or names
of the registered owner(s) appear(s) on the Certificates, and also must be
accompanied by such opinions of counsel, certifications and other information
as the Company or the Trustee for the Old Notes may require in accordance with
the restrictions on

                                                                             11
<PAGE>

transfer applicable to the Old Notes. Signatures on such Certificates or bond
powers must be guaranteed by an Eligible Institution.

6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS

   If New Notes are to be issued in the name of a person other than the signer
of this Letter of Transmittal, or if New Notes are to be sent to someone other
than the signer of this Letter of Transmittal or to an address other than that
shown above, the appropriate boxes on this Letter of Transmittal should be
completed (Box 7 and 8). Certificates for Old Notes not exchanged will be
returned by mail or, if tendered by book-entry transfer, by crediting the
account indicated above maintained at Euroclear or Cedelbank, as applicable.
See Instruction 4.

7. DETERMINATION OF VALIDITY

   The Company will determine, in its sole discretion, all questions as to the
form of documents, validity, eligibility (including time of receipt) and
acceptance for exchange of any tender of Old Notes, which determination shall
be final and binding on all parties. The Company reserves the absolute right
to reject any and all tenders determined by it not to be in proper form or the
acceptance of which, or exchange for, may, in the view of counsel to the
Company, be unlawful. The Company also reserves the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "The Exchange Offer--Conditions to the Exchange Offer"
or any conditions or irregularity in any tender of Old Notes of any particular
holder whether or not similar conditions or irregularities are waived in the
case of other holders.

   The Company's interpretation of the terms and conditions of the Exchange
Offer (including this Letter of Transmittal and the instructions hereto) will
be final and binding. No tender of Old Notes will be deemed to have been
validly made until all irregularities with respect to such tender have been
cured or waived. Neither the Company, any affiliates or assigns of the
Company, the Euro Exchange Agent, nor any other person shall be under any duty
to give notification of any irregularities in tenders or incur any liability
for failure to give such notification.

8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES

   Questions and requests for assistance may be directed to the Euro Exchange
Agent at its address and telephone number set forth on the front of this
Letter of Transmittal. Additional copies of the Prospectus, the Notice of
Guaranteed Delivery and the Letter of Transmittal may be obtained from the
Euro Exchange Agent.

9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9

   For U.S. Federal income tax purposes, holders are required, unless an
exemption applies, to provide the Euro Exchange Agent with such holder's
correct taxpayer identification number ("TIN") on Substitute Form W-9 of this
Letter of Transmittal (Box 9) and certify, under penalties of perjury, that
such number is correct and he or she is not subject to backup withholding. If
the Euro Exchange Agent is not provided with the correct TIN, the Internal
Revenue Service (the "IRS") may subject the holder or other payee to a $50
penalty. In addition, payments to such holders or other payees with respect to
Old Notes exchanged pursuant to the Exchange Offer, or with respect to New
Notes following the Exchange Offer, may be subject to 31% backup withholding.

   The box in Part 2 of the Substitute Form W-9 (Box 9) may be checked if the
tendering holder 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 2 is
checked, the holder or other payee must also complete the Certificate of
Awaiting Taxpayer Identification Number below Substitute Form W-9 in order to
avoid backup withholding. Notwithstanding that the box in Part 2 is checked
and the Certificate of Awaiting Taxpayer Identification Number is completed,
the Euro Exchange Agent will withhold 31% of all payments made prior to the
time a properly certified TIN is provided to the Euro Exchange Agent.

   The holder is required to give the Euro Exchange Agent the TIN (i.e.,
social security number or employer identification number) of the registered
owner of the Old Notes or of the last transferee appearing on the transfers
attached to, or endorsed

on, the Old Notes. If the Old Notes are registered in more than one name or
are not in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.

   Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below and check the box in Part 3 of
Box 9 for "exempt", to avoid possible erroneous backup withholding. A foreign
person may qualify as an exempt recipient by submitting a properly completed
IRS Form W-8, signed under penalties of perjury, attesting to that holder's
exempt status. Please consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which holders are exempt from backup withholding.

   Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. Federal income tax liability of a person 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.

10. LOST, DESTROYED OR STOLEN CERTIFICATES

   If any Certificate(s) representing Old Notes have been lost, destroyed or
stolen, the holder should promptly notify the Euro Exchange Agent. The holder
will then be instructed as to the steps that must be taken in order to replace
the Certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, destroyed or stolen
Certificate(s) have been followed.

11. SECURITY TRANSFER TAXES

   Holders who tender their Old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith. If, however, New Notes are to
be delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered, or if a transfer tax is imposed
for any reason other than the exchange of Old Notes in connection with the
Exchange Offer, then the amount of any such transfer tax (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.

   IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF) AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE EURO EXCHANGE AGENT ON OR PRIOR TO
THE EXPIRATION DATE.

   B. EXEMPT PAYEES--The following lists exempt payees. If you are exempt, you

that you are exempt. Check the box in Part 3 of the form, sign and date
the form.

   For this purpose, Exempt Payees include: (1) A corporation; (2) An
organization exempt from tax under section 501(a), or an individual retirement
plan (IRA) or a custodial account under section 403(b)(7); (3) The United
States or any of its agencies or instrumentalities; (4) A state, the District
of Columbia, a possession of the United States, or any of their political
subdivisions or instrumentalities; (5) A foreign government or any of its
political subdivisions, agencies or instrumentalities; (6) An international
organization or any of its agencies or instrumentalities; (7) A foreign
central bank of issue; (8) A dealer in securities or commodities required to
register in the U.S. or a possession of the U.S.; (9) A real estate investment
trust; (10) An entity or person registered at all times during the tax year
under the Investment Company Act of 1940; (11) A common trust fund operated by
a bank under section 584(a); (12) A financial institution.

   C. OBTAINING A NUMBER--If you do not have a taxpayer identification number
or you do not know your number, obtain Form SS-5, application for a Social
Security Number, or Form SS-4, Application for Employer Identification Number,
at the local office of the Social Security Administration or the Internal
Revenue Service and apply for a number.

   D. PRIVACY ACT NOTICE--Section 6109 requires most recipients of dividend,
interest or other payments to give taxpayer identification numbers to payers
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes. Payers must be given the numbers whether or not
payees are required to file tax returns. Payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
furnish a taxpayer identification number. Certain penalties may also apply.

E. PENALTIES

    (1) Penalty for Failure to Furnish Taxpayer Identification Number. If you
fail to furnish your taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.

    (2) Failure to Report Certain Dividend and Interest Payments. If you fail
to include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and
convincing evidence to the contrary.

    (3) Civil Penalty for False Information with Respect to Withholding. If
you make a false statement with no reasonable basis which results in no
imposition of backup withholding, you are subject to a penalty of $500.

    (4) Criminal Penalty for Falsifying Information. Falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.

   FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.
