ITEM 1. BUSINESS
 
The Company
 
   Exodus 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 and managed
services, which together provide the high performance, scalability and
expertise that enterprises need to optimize their 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 seamlessly 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
December 31, 1998, we had more than 800 customers, including installed and
uninstalled customers under contract, and managed over 6,000 customer servers.
Our customers represent a variety of industries, ranging from Internet-centric
companies such as Lycos, Inc., eBay Inc., MSN Hotmail (a subsidiary of
Microsoft Corporation), Yahoo! Inc., Inktomi Corporation and GeoCities, to
media companies such as MSNBC, USA Today Information Network, SportsLine USA,
Inc. and E-Online!, to Fortune 500 customers such as Applied Materials,
Hewlett-Packard Company and National Semiconductor Corporation.
 
   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 virtually all Internet-centric
businesses and are becoming increasingly mission-critical for many mainstream
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 that must be continuously upgraded to reflect changing
technologies and rapidly scale as the enterprise grows. Such a continuing
significant investment of resources is often an inefficient use of overall
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 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
 
                                      3
<PAGE>
 
mission-critical Internet operations. Our server hosting and Internet
connectivity services are offered through our Internet Data Centers' national
backbone network of multiple high speed DS-3, OC-3 and OC-12 lines, along with
our public and private network peering 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 restore services and security services. These services provide the
foundation for high performance, availability, scalability and reliability of
customers' Internet server operations. In addition, we integrate best-of-breed
technologies from leading vendors with our 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:
 
  .  extend our market leadership and position Exodus as the brand name and
     leader in this market;
 
  .  focus on enhancing systems and network management and Internet
     technology services;
 
  .  accelerate our domestic expansion and begin to establish a global
     presence;
 
  .  leverage our expertise to address new market opportunities such as e-
     commerce; 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. We currently operate eight Internet Data
Centers consisting of approximately 200,000 gross square feet, located in six
metropolitan areas: Boston, Los Angeles, New York, San Francisco, Seattle and
Washington, D.C. We also have a server hosting facility in the London
metropolitan area. In 1999, we plan to open additional Internet Data Centers
in the Washington, D.C. and Seattle metropolitan areas, and to open our first
Internet Data Centers in the Chicago and London metropolitan areas.
 
   We recently expanded our solutions and services by acquiring two providers
of Internet technologies, Arca Systems, Inc. ("Arca") and American Information
Systems, Inc. ("AIS"). 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.
 
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 our Internet Data Centers, network services and
managed 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
 
                                      4
<PAGE>
 
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 business and 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.

hosting services:

   Network Services--Internet Connectivity
 
   Exodus connects its Internet Data Centers through a high performance,
dedicated and redundant backbone ring with multiple high speed DS-3, OC-3 and
OC-12 lines, along with our public and private network peering
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.
 
                                      5
<PAGE>
 
   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. By the end of 1998, our network exchanged a
sustained 2.7 gigabits per second volume of traffic with the Internet during
peak periods. 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 36 national ISPs,
as well as public peering interconnections with over 120 ISPs.
 
   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 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 ever 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:

   We also offer professional services and intend to expand such services to
assist our customers in planning their strategies for managing mission-critical
Internet operations, transitioning such operations to our Internet Data Centers
and managing certain aspects of their Internet operations. These services can
be layered to allow customers to outsource an increasing portion of the
management of their Internet operations.
 
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 December 31, 1998, we had over 800 customers
(including installed and uninstalled customers under contract). The following
is a representative list of our Internet Data Center customers which generated
aggregate revenues for us in 1998 in excess of $15 million. These customers
represented in the aggregate approximately 30% of our 1998 revenues, and none
of such customers individually represented in excess of 10% of 1998 revenues.

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 December 31, 1998, we had 166 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 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,
Hewlett-Packard Company, 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.
 
  .  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 product demand through a broad range of marketing communications,
public relations, industry event sponsorship, as well as through our Web site.
Public relations focuses on cultivating industry analyst
 
                                      9
<PAGE>
 
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, to enhance our
customer service delivery and increase operating efficiencies 24x7, we
launched a centralized call center for our three San Francisco Internet Data
Centers. We intend to roll out a similar program to our other Internet Data
Centers. 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.
 
   Our contracts with customers generally cover the provision of services by
us for a one year period and may contain, among other things, certain 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, such customer's account would be credited for the charges
the customer paid for services it did not receive during such period. Between
August 1997 and July 1998, our service agreements typically included service
level warranties which provide that, if we fail to provide Internet Data
Center services to a customer for more than two consecutive hours, such
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,
such 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
 
                                     10
<PAGE>
 
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, many of our customers are within the
first year of their service contracts. We have had limited experience with
customers whose initial one year service contract terms have been completed
and whose contracts are therefore eligible for renewal.
 
   As of December 31, 1998, we had 214 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 eight 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 DS-
3 or OC-3 lines, provisioned by 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 DS-3, 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. DS-3, 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 peering interconnections with 36 national ISPs and public peering
interconnections with over 120 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 peering
interconnections at each of our Internet Data Centers, thus enhancing content
delivery. Our broad combination of private and public peering 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 such best-of-breed
technologies. We believe that establishing relationships with technology
leaders enables us to
 
                                     11
<PAGE>
 
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 "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Factors Affecting Future Results--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., Raptor Systems, Inc. and Sun Microsystems, Inc. Additionally,
we are developing a caching service with Inktomi Corporation. 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 ourself. As of December 31,
1998, we employed 18 persons in product development.
 
   Exodus incurred $444,000, $1.6 million and $3.2 million in product
development expenses during 1996, 1997 and 1998, respectively.
 
Competition
 
   Our market is intensely competitive. There are few substantial barriers to
entry, and we expect that we will face additional competition from existing
competitors and new market entrants in the future. 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 and equipment;
 
  .  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 and regional ISPs;
 
  .  global, regional and local telecommunications companies and Regional
     Bell Operating Companies; and
 
  .  large IT outsourcing firms.
 
                                     12
<PAGE>
 
   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 such 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.
 
Intellectual Property Rights
 
   We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect certain
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 certain foreign countries may not protect our products, services or
intellectual property rights to the same extent as do the laws of the United
States.
 
   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 such 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. Such royalty or licensing agreements might not be available on
terms acceptable to us or at all.
 
Government Regulation and Legal Uncertainties May Adversely Affect 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 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.

There are Risks Involved with 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
prohibits and imposes criminal penalties and civil liability on anyone engaged
in the business of selling or transferring, by means of the World Wide Web,
material that is harmful to minors without restricting access to such material
by persons under seventeen years of age. 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 certain service or product offerings.
Further, the costs of defending against such claims and potential adverse
outcomes of such 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.
 
   Certain businesses, organizations and individuals have in the past sent
unsolicited commercial e-mails advertising sites hosted at our facilities to
massive numbers of people, typically to advertise products or services. This
practice, known as "spamming," has led to some complaints against us. In
addition, certain 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, there can be no assurance that customers will not engage in this
practice, which could have a material adverse effect on our business.
 
Employees
 
   As of December 31, 1998, Exodus had 472 employees, including 166 employees
in sales and marketing, 18 employees in product development, 214 employees in
customer service, professional services and network engineering and 74
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 such personnel is intense, and there
can be no assurance that we will be able to identify, attract and retain such
personnel in the future. None of our employees is represented by a labor
union, and management believes that our employee relations are good. See
"Management's Discussion and Analysis of Financial Condition and Operating
Results--Factors Affecting Future Results--We Must Manage Growth Effectively"
and "--We Depend on Our Key Personnel."

   Most of our leases provide for a renewal option upon the expiration of the
initial term. We currently maintain sales offices in unutilized space in our
Internet Data Centers. We also have a server hosting facility in the London
metropolitan area. By the end of 1999, we plan to expand domestically and
internationally. This includes additional Internet Data Centers in the
Washington, D.C. and Seattle metropolitan areas. We also intend to open our
first Internet Data Centers in the Chicago and London metropolitan areas. We
have recently entered into leases for the space needed for additional sites in
the Washington, D.C. metropolitan area which covers approximately 88,000
square feet (which we will expand to approximately 120,000 square feet when we
build an additional floor) and expires in 2008, in the Seattle metropolitan
area which covers approximately 99,000 square feet and expires in 2009, in the
Chicago metropolitan area which covers approximately 48,000 square feet and
expires in 2010, and in the London metropolitan area which covers
approximately 41,000 square feet and expires in 2023.
 
ITEM 3. LEGAL PROCEEDINGS

   As of February 10, 1999, the number of stockholders of record was 284.
Because many of our shares are held by brokers and other institutions on
behalf of stockholders, we are unable to estimate the total number of
beneficial stockholders represented by these record holders.
 
   We have never declared or paid any cash dividends on our stock. We
currently intend to retain any earnings for use in our business and do not
anticipate paying any cash dividends in the foreseeable future.
 
   Use of Proceeds from Sales of Registered Securities.
 
   Our initial public offering of Common Stock was effected through a
Registration Statement on Form S-1 (File No. 333-44469) that was declared
effective by the SEC on March 18, 1998 and pursuant to which we sold an
aggregate of 5,125,000 shares of our Common Stock.
 
   As of December 31, 1998, we had used the estimated aggregate net proceeds
of $69.8 million from our initial public offering as follows:

   The foregoing amounts represent our best estimate of our use of proceeds
for the period indicated. No such payments were made to our directors or
officers or their associates, holders of 10% or more of any class of our
equity securities or to our affiliates.

ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA
 
   The following consolidated selected financial data should be read in
conjunction with our Consolidated Financial Statements and Notes thereto and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included elsewhere in this Form 10-K. The consolidated statement
of operations data for each of the years in the three-year period ended
December 31, 1998, and the consolidated balance sheet data as of December 31,
1997 and 1998, are derived from consolidated financial statements that have
been audited by KPMG LLP, independent auditors, and are included elsewhere in
this Form 10-K. The consolidated balance sheet data as of December 31, 1994,
1995 and 1996 and the consolidated statement of operations data for the year
ended December 31, 1995 are derived from consolidated financial statements
that have been audited by KPMG LLP that are not included herein. The
consolidated statement of operations data for the year ended December 31, 1994
are derived from unaudited consolidated financial statements that are not
included herein. 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 such periods. Historical results
are not necessarily indicative of the results to be expected in the future.

    amortization (including amortization of deferred stock compensation) and
    other noncash charges ("EBITDA"). 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

ITEM 7.  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 Consolidated Financial
Statements and Notes thereto included elsewhere in this Form 10-K. 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 differences
include, but are not limited to, those set forth under "--Factors Affecting
Future Results."
 
Overview
 
   We are 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 and managed
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 redundant high-performance national
Internet backbone ring.
 
   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.
We have derived most of our revenues from customers for which we provide these
services. Each of our Internet Data Center customers initially purchases a
subset of our service offerings to address specific departmental or enterprise
Internet computing needs, and some of these
 
                                     18
<PAGE>
 
customers purchase additional services as the scale and complexity of their
Internet operations increase. We sell our services under contracts that
typically have terms of one year. Customers pay monthly fees for the services
utilized, as well as one-time fees for installation and for equipment they
purchase from us.
 
   We opened our first Internet Data Center in the San Francisco metropolitan
area in August 1996. Since that time, we have opened seven additional domestic
Internet Data Centers in the metropolitan areas of New York (March 1997), San
Francisco (second site--August 1997; third site--June 1998), Seattle
(September 1997), Los Angeles (October 1997), Washington, D.C. (December 1997)
and Boston (July 1998), and we have a server hosting facility in London. See
"Business--Facilities." The building of Internet Data Centers has required us
to obtain substantial equity and debt financing. See "--Factors Affecting
Future Results--Our Substantial Leverage and Debt Service Obligations
Adversely Affect Our Cash Flow" and "--Liquidity and Capital Resources" below.
 
   In October 1998, we purchased 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.
 
   We intend to expand domestically and internationally. We expect to open
additional Internet Data Centers in the Chicago, Washington, D.C., Seattle and
London metropolitan areas in 1999. 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 an 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 "--Factors Affecting Future Results--
Rapid Expansion Produces a Significant Strain on Our Business" for risks
related to the foregoing forward-looking statements.
 
   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 quarterly and annual period. As of December 31, 1998, we
had an accumulated deficit of approximately $97 million. The revenue and
income potential of our business and market is unproven, and our limited
operating history makes an evaluation of us and our prospects difficult. We
intend to invest in new Internet Data Centers, product development, sales and
marketing programs, and therefore we believe that we will continue to
experience net losses on a quarterly and annual basis for the foreseeable
future. Companies, such as Exodus, in the new and rapidly evolving market for
Internet system and network management solutions encounter risks, expenses and
difficulties that affect their business and prospects. There can be no
assurance that we will ever achieve profitability on a quarterly or an annual
basis or will sustain profitability if achieved. See "--Factors Affecting
Future Results--Our Short Operating History and Heavy Losses Make Our Business
Difficult to Evaluate" for risks related to the foregoing forward-looking
statements.

   Revenues
 
   Our revenues consist of (i) monthly fees from customer use of Internet Data
Centers, network services and managed services, (ii) revenues from sales of
third-party equipment to customers and (iii) one-time fees for installation.
Currently, substantially all of our revenue is derived from services. Revenues
(other than installation fees and equipment sales to customers) are generally
billed and recognized ratably over the term of the contract, 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.
 
   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. We sell third-party equipment to our customers as an
accommodation to facilitate their purchase of services. Equipment revenues
increased 21% from $676,000 in 1996 to $820,000 in 1997 and 257% to $2.9
million in 1998.
 
   Cost of Revenues
 
   Our cost of revenues is comprised primarily of our costs for our nationwide
backbone network and local telco loops, depreciation, 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 costs of third-party
equipment sold to customers.
 
                                     20
<PAGE>
 
   Cost of service revenues increased from $2.5 million in 1996 to $16.2
million in 1997 and to $59.2 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 network backbone and local telco 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 such investments in Internet Data
Centers and network infrastructure relative to the growth in associated
revenue. The decrease in cost of service revenue as a percentage of revenue
from 1997 to 1998 resulted from revenues from new and existing Internet Data
Centers increasing faster than related costs of revenues. Costs for our
network backbone and local telco 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.
 
   Marketing and Sales
 
   Our marketing and sales expenses are comprised primarily 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 $28.8 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 $10.4 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.
 
   General and Administrative
 
   Our general and administrative expenses are comprised primarily of salaries
and benefits for our administrative and management information systems
personnel and fees paid for professional services and recruiting.
 
   Our general and administrative expenses increased from $1.1 million in 1996
to $6.0 million in 1997 and to $15.9 million in 1998. These increases were
primarily the result of increased 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 $2.6 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
 
                                     21
<PAGE>
 
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. See "--Stock
Compensation Expense" below. 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.
 
   Product Development
 
   Our product development expenses are comprised 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 $3.2 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.
 
   Net Interest Expense
 
   Our net interest expense increased from $39,000 in 1996 to $506,000 in 1997
and to $9.8 million in 1998. The increases 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
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.
 
   We expect that net interest expense will continue to increase as we enter
into additional equipment leases and loans, obtains additional borrowings and
long term debt and as interest income is reduced resulting from the decline in
our cash reserves to fund working capital and other uses.
 
   Stock Compensation Expense
 
   We had no stock compensation expense in 1996. During 1997, we recorded
deferred stock compensation of approximately $3.5 million in connection with
the grant of certain stock options from March through December 1997. This
amount is generally amortized over the 50 month vesting period of such
options. Of this amount, approximately $1.1 million was amortized in 1997 and
$1.3 million was amortized in 1998. This amortization is being recorded in a
manner consistent with FASB Interpretation No. 28. See Note 5 of Notes to
Consolidated Financial Statements.
 
   EBITDA
 
   Our loss before interest, taxes, depreciation, amortization and other non-
cash charges ("EBITDA") was $3.6 million in 1996, $20.3 million in 1997 and
$41.1 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. Although EBITDA should not be used as an alternative to operating
 
                                     22
<PAGE>
 
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
 
   Since inception and through December 31, 1998, we have financed our
operations primarily through private sales of preferred stock, our initial
public offering in March 1998, our senior notes offering in July 1998 and
through various types of equipment loans and lease lines and working capital
lines of credit. At December 31, 1998, our principal sources of liquidity were
$150.9 million of cash and cash equivalents. As of that date, we also had
equipment loans and lease lines and working capital lines of credit under
which we could borrow up to an additional aggregate of $5.4 million for
purchases of equipment and for working capital. As of December 31, 1998, our
total bank borrowings, equipment loans and lines of credit facilities, capital
lease obligations and senior notes were $246.6 million. See Notes 4 and 6 of
Notes to Consolidated Financial Statements. In addition, we expect to enter
into one or more new credit facilities, under which we will be permitted to
borrow up to approximately $50.0 million upon meeting certain financial tests.
The Credit Facility is expected to be secured by a first priority lien on
substantially all of our assets (subject to certain exceptions) and the assets
and stock of any future subsidiaries. There can be no assurance as to whether,
or on what terms, we will enter into the Credit Facility.
 
   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 year ended December 31, 1998 was $46.5 million,
primarily due to net losses, offset in part by increases in accrued expenses,
accounts payable and depreciation and amortization. This compares to net cash
used for operating activities for the year ended December 31, 1997 of $15.5
million, primarily due to net losses, offset in part by increases in accrued
expenses, accounts payable and depreciation and amortization.
 
   Net cash used for investing activities for the year ended December 31, 1998
was $92.7 million compared to $23.9 million for the year ended December 31,
1997. Net cash used for investing activities was due to capital expenditures
for the continued construction of Internet Data Centers, the acquisition of
Arca and the investment of funds held in escrow for interest payments on the
senior notes. Cash provided by financing activities for the year ended
December 31, 1998 was $279.9 million, primarily due to the proceeds from our
issuance of $200 million of senior notes and our initial public offering. This
compares to net cash provided by financing activities for the year ended
December 31, 1997 of $45.9 million due to the proceeds of the issuance of
preferred stock and warrants and proceeds from equipment loans and line of
credit facilities.
 
   As of December 31, 1998, we had commitments under capital leases and under
noncancellable operating leases of $19.9 million and $91.1 million,
respectively, through 2010. We intend to make significant expenditures during
the next 12 months primarily for property and equipment, in particular
equipment 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 existing and future equipment loans and lease
lines, net proceeds from the senior notes and borrowings under the expected
Credit Facility. We expect to meet our working capital and capital expenditure
requirements over the next 12 months with existing cash and cash equivalents
and short-term investments, borrowings under the expected Credit Facility,
cash from sales of services and proceeds from existing and future working
capital 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 generating sufficient cash flows from
operations or raising capital in sufficient amounts on terms acceptable to us.

Significant Strain on Our Business."

Factors Affecting Future Results
 
   Our Short Operating History and Heavy Losses Make Our Business Difficult to
   Evaluate
 
   Our limited operating history makes an evaluation of our business
operations and our prospects difficult. We began offering server hosting and
Internet connectivity services in 1995 and opened our first dedicated Internet
Data Center in August 1996. With such a short operating history, our business
model is still in an emerging state. We have incurred operating losses and
negative cash flows each quarter and year since 1995. Our accumulated deficit
was approximately $97.0 million at December 31, 1998. We anticipate making
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 to acquire complementary businesses, products,
services or technologies. Although we have experienced significant growth in
revenues in recent periods, we do not believe that this growth rate is
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 timely 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,
certain substantial interest expenses, real estate and personnel. Therefore,
our results of operations are particularly sensitive to fluctuations in
revenues. Also, if our agreement with Computer Associates were to terminate
and we continued to require Computer Associates' software, the license fees
paid by us could increase fixed costs. Furthermore, if we were to
 
                                     24
<PAGE>
 
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 in an emerging stage, and there is the
possibility that we will not be able to collect receivables on a timely basis.
 
   Rapid Expansion Produces a Significant Strain on Our Business
 
   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 eight Internet Data Centers located in six metropolitan
areas: Boston, San Francisco, New York, Los Angeles, Seattle and Washington,
D.C., and we have a server hosting facility in the London metropolitan area.
We expect to open additional Internet Data Centers in 1999. To successfully
expand, we must be able to assess markets, locate and secure new Internet Data
Center sites, install facilities and establish additional peering
interconnections with Internet service providers in a timely manner and at a
reasonable cost. To manage this expansion effectively, we must continue to
improve our operational and financial systems and expand, train 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 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 respond to competitive pressures.
 
   It usually 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
experience further losses 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 Must Manage Growth Effectively
 
   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 customer base and increase in the number of
employees. This growth has placed, and if it continues, will 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 may be 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. If our executives are unable to
manage growth effectively, our business could be materially adversely
affected.
 
                                     25
<PAGE>
 
   Risks Associated with Acquisitions
 
   In October 1998 we acquired the assets of Arca and in February 1999 we
acquired AIS. We continue to expend resources integrating these new businesses
and the personnel hired in connection with such acquisitions. We believe that
our future growth depends, in part, upon the acquisition of complementary
businesses, products, services or technologies. If we buy 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 employees and increase our expenses. In addition,
future acquisitions by us may result in the incurrence of additional debt,
large one-time write-offs and the creation of goodwill or other intangible
assets that could result in amortization expenses.
 
   Our Substantial Leverage and Debt Service Obligations Adversely Affect Our
   Cash Flow
 
   We have substantial amounts of outstanding indebtedness. 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 indebtedness
when due. As of December 31, 1998, we had indebtedness of approximately $246.6
million and available borrowings of up to an additional $5.4 million. We
expect to enter into a new secured credit facility under which we could borrow
up to $50.0 million. We also expect to add additional equipment loans and
lease lines to finance capital expenditures for our Internet Data Centers and
may obtain additional long term debt, working capital lines of credit and
lease lines. There can be no assurance that any such 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;
 
  .  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 vis-a-vis less
     leveraged competitors and competitors that have better access to capital
     resources.
 
   We Are Subject to Restrictive Covenants That Limit Our Flexibility
 
   Our Senior Notes contain various restrictions on our ability to incur
indebtedness, pay dividends or make other restricted payments, sell assets,
enter into affiliate transactions and take other actions. Furthermore, certain
of 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 certain financial ratios and comply with
covenants restricting our ability to incur indebtedness, pay dividends or make
other restricted payments, sell assets, enter into affiliate transactions or
take other actions.
 
   We Compete With Much Larger Companies and There Are Few Barriers to Entry
 
   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. The principal competitive factors in
this market include:
 
  .  Internet system engineering and other expertise;
 
  .  customer service;
 
                                     26
<PAGE>
 
  .  network capability, reliability, quality of service and scalability;
 
  .  the variety of services offered;
 
  .  access to network resources, including circuits and equipment;
 
  .  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 and regional ISPs;
 
  .  global, regional and local telecommunications companies and Regional
     Bell Operating Companies; and
 
  .  large IT outsourcing firms.
 
   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 such 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.
 
   Our Market Is New and Our Services May Not Be Generally Accepted
 
   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 materially and adversely affected. In addition, in order to be
successful we must be able to differentiate ourselves from our competition
through our service offerings.
 
 
                                     27
<PAGE>
 
   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 or Qwest Communications
Corporation, to provide consistent data communications capacity 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 is Critical to Our Success
 
   Our customer contracts generally provide a limited service level warranty
related to the continuous availability of service on a 24 hours per day, seven
days per week basis. This warranty 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 warranty. If we incur significant warranty obligations in
connection with system downtime, our liability insurance may not be adequate
to cover such expenses. As customers outsource more mission-critical
operations to us, we may be subject to increased liability claims and customer
dissatisfaction should our systems fail or our customers otherwise become
unsatisfied.
 
   Our Ability to Expand Our Network Is Unproven
 
   To satisfy customer requirements, we must continue to expand and adapt our
network infrastructure. We are dependent on MCI WorldCom and Qwest and certain
other telecommunications providers for our backbone capacity, including our
dedicated clear channel network and transit access to ISPs. 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 quickly increase 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, consumer demand could shrink 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 Certain Network Interconnections
 
   We rely on a number of public and private network interconnections,
commonly referred to as peering relationships, to allow our customers to
connect to other networks. If our peering partners were to discontinue their
support for the peering relationships, our ability to exchange traffic would
be significantly constrained. Furthermore, our business will be adversely
affected if these peering partners do not add more bandwidth to accommodate
increased traffic. Many of the companies with which we maintain private
peering interconnections are our competitors. There is nothing to prevent any
peering partners, many of which are significantly larger than us, from
charging high usage fees or
 
                                     28
<PAGE>
 
denying access. In the future, private peering partners could refuse to
continue to interconnect directly with us, might impose significant costs on
us or limit our customers access to their networks. If we were unable on a
cost-effective basis to access alternative networks to exchange our customers'
traffic or if we were unable to pass through to our customers any additional
costs of utilizing these networks, our business could be materially adversely
affected.
 
   Risks Associated with International Operations
 
   A component of our strategy is to expand into international markets,
including Europe and Japan, and we currently have a server hosting site in the
London metropolitan area. We expect to open an Internet Data Center in the
London metropolitan area in the second quarter of 1999. In order to expand
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 will 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.
 
   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, and we may not be able to incorporate
advances on a cost-effective and timely basis. Moreover, technological
advances may have the effect of encouraging certain of 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
 
                                     29
<PAGE>
 
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 and therefore may 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. Certain 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 or others. Furthermore, such 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. This could
result in liability to us and the loss of existing customers or the deterrence
of potential customers. The costs required to eliminate computer viruses and
alleviate other security problems could be prohibitively expensive and the
efforts to address such 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 certain 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. Our failure to obtain
required products or services on a timely basis and at an acceptable cost
would have a material adverse effect on our business. In addition, the failure
of our sole or limited source suppliers to provide products or components that
comply with evolving Internet and telecommunications standards or that
interoperate with other products or components we use could have a material
adverse effect on our business. In addition, we expect to depend for a time on
third parties to deliver our services from and manage our international
operations, including our site in London.
 
   We also license certain software from Computer Associates that allows us to
monitor our customers' Internet operations and assist in resolving performance
issues that arise from time to time. Under the agreement with Computer
Associates, if we desire to offer a service that has a substantially similar
functionality to that provided by Computer Associates' Unicenter(R) TNG(TM)
family of software, or its ARCserve or InocuLAN products, we must generally
utilize Computer Associates products as long as they meet our requirements. In
addition, we are a beta test site for new versions of Computer Associates
products and we must, upon commercial deployment, replace existing software
with new Computer Associates products if they are substantially similar in
functionality. During the term of the agreement, we are obligated to pay
Computer Associates a royalty equal to one percent of our gross revenues.
Either party may terminate this agreement upon 60 days' prior written notice
with no
 
                                     30
<PAGE>
 
penalties. Should this agreement be terminated, we have the right to continue
licensing software from Computer Associates at a forty percent discount for
five years and we would no longer be obligated to pay a royalty to Computer
Associates.
 
   Government Regulation and Legal Uncertainties May Adversely Affect 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 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.
 
   There are Risks Involved with 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 such 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 certain service or product offerings. Further,
the costs of defending against any such claims and potential adverse outcomes
of such 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.
 
   Certain businesses, organizations and individuals have in the past sent
unsolicited commercial e-mails advertising sites hosted at our facilities to
massive numbers of people. This practice, known as "spamming," has led to some
complaints against us. In addition, certain 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, there can be no assurance that customers
will not engage in this practice, which could have a material adverse effect
on our business.
 
   We Depend on Our Key Personnel
 
   Our success depends in significant part upon the continued services of our
key technical, sales and senior management personnel. Although certain of our
executive officers participate in our executive employment policy, none of our
officers is a party to an employment agreement. Any officer
 
                                     31
<PAGE>
 
or employee can terminate his or her relationship at any time. The loss of the
services of one or more of our key employees or our failure to attract
additional qualified personnel could have a material adverse effect on our
business. We do not carry key-person life insurance for any of our employees.
 
   We Depend on the Internet and Internet Infrastructure Development
 
   Our success will depend 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.
 
   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 certain
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 certain foreign countries may not protect our products, services or
intellectual property rights to the same extent as do the laws of the United
States.
 
   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 such 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. Such royalty or licensing agreements might not be available on
terms acceptable to us or at all.
 
   Volatility of Our Stock Price
 
   The market price of our common stock has fluctuated in the past and is
likely to continue to fluctuate. In addition, the securities markets,
particularly with respect to Internet stocks, have experienced significant
price and volume fluctuations.
 
   Risk Related to the Year 2000 Problem
 
   The Year 2000 problem stems from the use of a two digit date to represent
the year (e.g., 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. Software
so created may be unable to properly address dates after 1999. 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 information related
 
                                     32
<PAGE>
 
to the date change adequately. 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. In addition,
any costs of defending and resolving any Year 2000 related disputes, and any
liability for Year 2000-related damages, including consequential damages,
could have a material adverse effect on our business.
 
   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 information technology (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). The program has
several phases that overlap, all of which will be completed with issues
identified to be resolved by the end of the third quarter of 1999. Our
internal inventory audit was completed January 1999. In addition, we plan to
have an independent review of our Year 2000 assessment completed in the second
quarter of 1999, with final Year 2000 compliance expected in the third quarter
of 1999.
 
   In addition, we may acquire businesses or assets which contain systems that
must be made Year-2000 compliant. For instance, with respect to our
acquisition of AIS we plan to remedy any identified Year 2000 issues and test
the solutions adopted during the second quarter of 1999.
 
   We have established procedures for evaluating and managing the risks and
costs associated with this 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, to resolve Year 2000 issues, other than
unanticipated liabilities, should not exceed $500,000. We further estimate
that the time and effort required of our personnel to resolve Year 2000 issues
will not be material.
 
   Our Year 2000 initiative specifically addresses processes and methods in
eleven focused areas:
 
  Assess Situation
 
    .  Understand the scope and magnitude of Year 2000 problems to our
       organizational systems and operations.
 
    .  Define our objective for Year 2000 compliance, develop an inventory
       of our systems, assess the impact of Year 2000 on these systems, and
       identify candidate solutions for addressing Year 2000 problems.
 
  Analyze Candidate Solution
 
    .  Perform studies and analyses resulting in the selection of a solution
       to meet the Year 2000 problem and its defined constraints.
 
    .  Define approach and evaluation criteria for the analysis, select the
       candidate solutions, and implementation.
 
  Plan Technical Effort
 
    .  Establish plans that provide the basis for scheduling, costing,
       controlling, tracking and negotiating the nature and scope of
       technical work involved in transitioning a system to Year 2000
       compliance.
 
    .  Develop estimates for the work to be performed, obtain necessary
       commitments from interfacing groups, and define plan to perform the
       work.
 
                                     33
<PAGE>
 
  Monitor and Control Technical Effort
 
    .  Provide adequate visibility into actual progress and risks.
 
    .  Involves directing, tracking, and reviewing the project's
       accomplishments, results and risks against its documented estimates,
       commitments and plans.
 
  Ensure Quality
 
    .  Address not only the quality of Year 2000 compliant systems but also
       the quality of the process used to produce those systems.
 
    .  Involves objective verification of a project's activities with
       respect to its plans and work products (e.g., code) to our
       standards.
 
  Manage Configurations
 
    .  Maintain data on identified configuration units and analyze and
       control changes to the systems and its configuration units.
 
    .  Provide accurate and current configuration data to internal
       personnel and external vendors for all work products placed under
       configuration management.
 
  (Re)Engineer Products/Data
 
    .  Consistently perform a well-defined engineering process that
       integrates all engineering activities involved in
       developing/converting products/services meeting the requirements for
       Year 2000 compliance as defined by us.
 
    .  Specify change requirements for Year 2000 compliant systems, develop
       designs to accommodate those requirements, implement the
       corresponding designs in software and perform testing of those
       implementations.
 
  Integrate Systems
 
    .  Ensure that system elements, and the system as a whole, will
       function in accordance with requirements when the elements operate
       in conjunction with each other and with other external systems.
 
    .  Identify, define and control interfaces.
 
    .  Verify system functions whose successful operation involves more
       than one system element throughout the entire product life cycle.
 
  Verify and Validate Systems
 
    .  Ensure that the development/supplier team performs increasingly
       comprehensive evaluations to ensure evolving work products meet all
       requirements.
 
    .  Scope covers development of the full system/service, as well as its
       production, operation, delivery and support.
 
    .  Measures customer loyalty on the basis of the customer's operational
       needs and continues throughout product/service life.
 
  Oversee and Manage Subcontracts
 
    .  Ensure that acquisition (outsourcing) of services for development of
       Year 2000 compliant software keeps risks to an acceptable minimum.
 
    .  Ensure that both the operation of the software resulting from such
       contracts and the data processing by the products under such
       contracts meets our requirements for Year 2000 compliance.
 
                                     34
<PAGE>
 
  Oversee and Manage Acquisitions
 
    .  Ensure that acquisitions of commercial off-the-shelf tools and/or
       software for Year 2000 compliance keeps risks to an acceptable
       minimum.
 
    .  Ensure that both operation of the software resulting from such
       contracts and the data processed by the products under such
       contracts meets our requirements for Year 2000 compliance.
 
   The above eleven focus areas provide an instrument for analyzing our
organizational process to assure our preparedness for Year 2000 business
operations. It also reviews both technical and managerial practices to ensure
effective management of the Year 2000 conversion or compliant-product
development process. Lastly, we see this as an effective process for
identifying our strengths and weaknesses with respect to Year 2000 practices.
Results of our YEAR 2000 initiative to date in specific target area is as
follows.
 
   Our Services and Products. We have determined that our Internet Data Center
equipment is either currently Year 2000 compliant or that a funded
replacement/upgrade plan is in place to resolve known 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 either "Year 2000
compliant" or will not require substantial effort or cost to make them Year
2000 compliant by the end of the third quarter of 1999. We are also in the
process of a complete asset inventory and final asset analysis assessment.
This review is being conducted to re-validate previous Year 2000 assessments
conducted by the management of our individual departments. These departmental
programs and assessments are now part of a coordinated unified company-wide
Year 2000 initiative.
 
   Our Vendor Relations. 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. We recognize that we face additional risk to the extent that
suppliers of products, services and systems purchased by us and others with
whom we transact business are not Year 2000 compliant. 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 will be developing contingency plans to address specific vendor/service
provider concerns.
 
   Internal Operations. We have reviewed, and continue to review, internal
management information and other systems in order to identify and modify those
products, services or systems that may not be Year 2000 compliant. Based on
our assessment to date, we believe that internal management information and
other systems are either Year 2000 compliant or will not require substantial
effort or cost to make them Year 2000 compliant. We do not foresee any issues
with internal IT and internal non-IT systems being Year 2000 compliant by the
end of the third quarter of 1999.
 
   Customer Risks. 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
 
                                     35
<PAGE>
 
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.
 
   Year 2000 Risk Summary. 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 such problems will not have a material adverse
effect on our business.
 
   Recent Accounting Pronouncements
 
   In March 1998, the AICPA issued SOP No. 98-1, Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use. SOP No. 98-1
requires entities to capitalize certain costs related to internal-use software
once certain criteria have been met. We expect that the adoption of
SOP No. 98-1 will not have a material impact on our financial position,
results of operations or cash flows. We will be required to implement SOP No.
98-1 for the year ending December 31, 1999.
 
   In April 1998, the AICPA issued SOP No. 98-5, Reporting on the Costs of
Start-Up Activities. SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, all start-up costs
that were capitalized in the past must be written off when SOP No. 98-5 is
adopted. We expect that the adoption of SOP No. 98-5 will not have a material
impact on our financial position, results of operations or cash flows. We will
be required to implement SOP No. 98-5 for the year ending December 31, 1999.
 
   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 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, 2000.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
 
   We have limited exposure to financial market risks, including changes in
interest rates. The fair value of our investment portfolio or related income
would not be significantly impacted by a 100 basis point increase or decrease
in interest rates due mainly to the short-term nature of the major portion of
our investment portfolio. 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 have any significant
foreign operations and thus are not materially exposed to foreign currency
fluctuations.

end of their respective ten-year terms. These gains are based on assumed rates
of annual compound stock price appreciation of 5% and 10% from the date the
option was granted to the end of the option terms.

(1) These options were generally granted at fair market value, except for the
    option granted to Mr. Chandrasekhar with an exercise price per share of
    $18.00, which was above fair market value. The options generally vest over
    a 50-month period so long as the individual is employed by us, except that
    the two options granted to Mr. Chandrasekhar, each for 166,667 shares of
    Common Stock at per share exercise prices of $9.00 and $18.00,
    respectively, vest in full upon the third and fifth anniversaries of the
    date of grant (January 27, 1998), respectively. Both options will
    accelerate and become fully vested if we are acquired or sell all or
    substantially all of our assets or if Mr. Chandrasekhar is terminated

   Executive Employment Policy. In December 1997, the Board adopted a form of
Executive Employment Policy (the "Policy") to be entered into between us and
each of our executive officers and certain of our other employees (together,
the "Executives"). Pursuant to the Policy, in the event of a "Termination" (as
defined in the Policy) resulting from a "Change of Control" (as defined in the
Policy), each Executive's base salary and medical benefits would continue for
18 months for the Chairman, Chief Executive Officer and President, and up to
12 months for other Executives. In addition, in the event of a Change in
Control, each Executive's options would become exercisable with respect to 50%
of such Executive's remaining unvested shares subject to such options. In the
event of an "Involuntary Termination" (as defined in the Policy), base salary
and medical benefits would generally continue for shorter time periods than
those set forth above and the Executive's options would continue to vest
during such period. An Executive that "Voluntarily Terminates" (as defined in
the Policy) or is terminated for "Cause" (as defined in the Policy) would
generally not receive any compensation, additional stock option vesting or
other benefits after the date of termination. Pursuant to the Policy, during
the term of any payments made to an Executive after termination, such
Executive would not be permitted to manage, operate, control, participate in
the management, operation or control of or be employed by any other person or
entity that is engaged in providing services that are directly competitive
with the services offered by us.
 
Director Compensation
 
   Our directors do not receive cash compensation for their services as
directors but are reimbursed for their reasonable expenses in attending
meetings of the Board. Under our 1998 Directors Stock Option Plan, each member
of the Board who is not our employee is automatically granted an option for
20,000 shares upon joining the Board, which will vest as to 33 1/3% of the
total shares on each annual anniversary of the date of grant provided the
optionee is still a member of the Board or a consultant to us. In 1998,
directors Lynch and Hopper each received an option for 20,000 shares at an
exercise price of $15.00 per share. At each annual meeting of stockholders,
each eligible director will automatically be granted an additional option for
5,000 shares, which will vest as to 25% of the total shares on each annual
anniversary of the date of grant provided the optionee is still a member of
the Board or a consultant to us. In May 1998, directors Bolander, Dougery,
Dubovoy, Hopper,
 
                                     43
<PAGE>
 
Howley, Lynch, Mocarski and Rekhi each received an option for 5,000 shares at
an exercise price of $30.688 per shares.
 
   In February 1998, we sold shares of Series D Preferred Stock convertible
into 33,333 and 5,848 shares of Common Stock at a purchase price per share of
$8.55 to directors Lynch and Hopper, respectively. Such shares have since been
converted into Common Stock.
 
Compensation Committee Interlocks and Insider Participation
 
   None of the members of the Compensation Committee of the Board, consisting
of directors Bolander, Howley and Mocarski, was at any time during 1998 an
officer or employee of Exodus. No executive officer of Exodus served during
1998 or serves as a member of the board of directors or compensation committee
of any entity that has one or more executive officers serving on our Board or
our Compensation Committee.

                   REPORT OF KPMG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Exodus Communications, Inc.:
 
   We have audited the consolidated financial statements of Exodus
Communications, Inc. and subsidiaries (the Company) as listed in the
accompanying index. In connection with our audits of the consolidated
financial statements, we have also audited the financial statement schedule as
listed in the accompanying index. These consolidated financial statements and
financial statement schedule 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 basic 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
 
(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 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
 
   Revenues consist of (i) monthly fees from customer use of Internet Data
Centers and related services and installation, and (ii) equipment sales to
customers. Revenues (other than installation fees and equipment sales to
customers) are billed monthly and recognized ratably over the term of the
contract, generally one year. Installation fees are typically recognized at
the time that installation occurs, and equipment sales are typically
recognized when the equipment is delivered to the customer or placed into
service at the Internet Data Center.
 
   Cash Equivalents and Investments
 
   Cash equivalents consist of highly liquid investments with original
maturities of 90 days or less. As of December 31, 1998, cash equivalents
consisted principally of money market funds at two financial institutions.
 
   The Company classifies its investments as "held-to-maturity." As of
December 31, 1998, such investments consist of United States Treasury Notes
and are recorded at amortized cost.
 
   The components of restricted cash equivalents and investments as of
December 31, 1998, are as follows (in thousands):

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
                       December 31, 1996, 1997 and 1998
 
 
   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 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 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

                       December 31, 1996, 1997 and 1998
 
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.
 
   Goodwill and Other Intangible Assets
 
   Goodwill and other intangible assets are comprised of amounts recorded in
the acquisition of Arca Systems, Inc. ("Arca") and are included in other
assets on the accompanying 1998 consolidated balance sheet (see Note 2). These
amounts are being amortized on a straight-line basis over 10 years.
 
   Net Loss Per Share
 
   Basic and diluted net loss per share has been computed by dividing the net
loss attributable to common stockholders by the weighted-average number of
shares of common stock outstanding during the period. Diluted net loss per
share does not include the effect of the following common equivalent shares as
the effect of their inclusion is antidilutive during each period (in
thousands):

   There are no differences between consolidated net loss and comprehensive
loss for any period presented.
 
(2) Business Combination
 
   On October 2, 1998, the Company purchased substantially all of the assets,
including customer agreements, and assumed certain liabilities of, 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 with the results of Arca 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).

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

expected life--contractual term; risk-free interest rates--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
     the carrying value of the Series C redeemable convertible preferred
     stock and recorded as the carrying value of the Series C warrants.
 
  .  The 247,826 and 125,000 warrants issued in connection with the
     $8,000,000 line of credit facility and $5,000,000 equipment line of

     a straight-line basis through the commitment periods of the credit
     facilities.

   As of December 31, 1997 and 1998, the Company has 18,663 and 181,085
warrants to purchase common stock outstanding, respectively.
 
   Initial Public Offering
 
   On March 24, 1998, the Company completed its initial public offering
("IPO") of 5,125,000 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 366,667
shares of common stock were authorized. Awards totaling 107,368 shares of
common stock were granted to individuals through 1996, at a price of $0.24 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, 4,301 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, 46,301 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 600,000 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, 54,566 shares were issued under the Purchase Plan at a weighted-
average purchase price of $13.36 per share.

                       December 31, 1996, 1997 and 1998
 
 
   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 six months from the date of grant and 2% per month
thereafter, and generally are exercisable for a term of ten years after the
date of grant. Under the 1997 Plan, the Company reserved 2,200,000 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 six months from the date of grant and 2% per
month thereafter and are generally exercisable for a term of ten 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
1,500,000 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 ten years and generally will vest over
50 months. The 1998 Plan will terminate in January 2008.
 
   In January 1998, the Company adopted the 1998 Directors Stock Option Plan
(the "Directors Plan") and reserved a total of 200,000 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 20,000 shares of the Company's common stock and, thereafter, an
option to purchase an additional 5,000 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 333,334
shares of common stock to an officer of the Company, of which half have an
exercise price of $9.00 per share and vest 100% after three years and half
have an exercise price of $18.00 per share and vest 100% after five 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 721,981 shares of common stock with an exercise price of
$9.00 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 2,000,000 shares of
common stock for issuance to employees, consultants, and to be used for
acquisitions, to be granted as nonqualified stock options.

                       December 31, 1996, 1997 and 1998
 
Options granted under the 1999 Plan generally will vest over 50 months and are
generally exercisable for a term of ten 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 from
March through December 1997. With respect to the stock options granted 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.

(6) Commitments and Contingencies
 
   Leases
 
   The Company has entered into a number of operating leases for its
facilities. The leases expire from 1998 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

   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.

   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.

                       December 31, 1996, 1997 and 1998
 
   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 currently operates eight Internet Data Centers throughout the
United States. 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 their servers in multiple data centers. As a
result, the Company believes these 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.
 
   The total revenues of the Internet Data Centers is the same as the
Company's total consolidated revenues for all periods presented in the
accompanying consolidated statements of operations. Segment profit or loss for
the Internet Data Centers is measured by total revenues less cost of revenues
and marketing and sales expenses. Other operating expenses as well as net
interest expense are not allocated.
 
   As of December 31, 1998, over 75% of property and equipment relates to the
Internet Data Centers. No other assets of the Company are allocated to the
Internet Data Centers.
 
(9) Subsequent Event--Unaudited
 
   In February 1999, the Company acquired American Information Systems, Inc.
for approximately $20,000,000 in cash. This acquisition will be accounted for
under the purchase method of accounting.

Dear Susan,

I am pleased to extend to you an offer as Vice President, Marketing and Strategy
reporting to Ellen Hancock. Your initial base salary will be $16,666.67 per
month, which is equivalent to $200,000.00 per year. You will be eligible to
participate in the company Executive Bonus Program, initially at 75% of your
base salary and fully guaranteed for the first year. You will be covered by the
attached Executive Employment Policy with the addendum as noted. You also will
be eligible to participate in our health and dental insurance, 401K and other
employee benefits established by the Company.

This offer includes a one-time hire bonus of $75,000.00. This bonus is payable
after the completion of 90 days of employment and shall be repaid to Exodus
should you voluntarily terminate employment with Exodus within one year of your
start date.

We will recommend to the Compensation Committee of the Company that you be
granted options to purchase up to 150,000 shares of Exodus Communications, Inc.
common stock under the Exodus' Equity Incentive Plan. The options, if approved
by the Committee, will be granted at the first Compensation Committee meeting
after your date of hire. The exercise price will be the closing price of the
common stock on the date of the Compensation Committee meeting. The options have
a vesting period of 50-months beginning on your date of hire. Six months of
continuous employment is required before you vest. At the conclusion of six
months from your employment date you will be 12% vested. You will then vest at a
rate of 2% per month of completed service until your grant is fully vested.

As an employee of Exodus Communications, Inc., you will have access to certain
Company confidential information and you may, during the course of your
employment, develop certain information or inventions, which will become the
property of Exodus. You will need to sign the Company's standard "Proprietary

to impress upon you that we do not wish you to bring with you any confidential
or proprietary material of any former employer or to violate any other
obligation to your former employers. Also, you represent that you are not
subject to any restrictions that prevent you from working for Exodus.

Your employment with Exodus is conditioned upon your providing verification of
your eligibility for employment in the U.S., which meets the requirements of the
U.S. Department of Justice and passing our background investigation.

          Royal Institution of Chartered Surveyors or the person acting on his
          behalf thinks fit he may discharge the valuer and appoint another in
          his place.

     For the purpose of this clause the revised rent shall be deemed to have
     been ascertained on the date when it has been agreed between the Landlord
     and the Tenant or the date of the determination by the valuer.

     insurance in respect of the Property, the Tenant shall pay to the Landlord
     all monies received by virtue of the insurance to enable the Landlord to
     apply them in making good the loss or damage in respect of which they have
     been received.

(12) CESSER OF RENT

     If the Property or any part of it (or the means of access to or egress from
     it) is destroyed or damaged by any of the Insured Risks so as to be unfit
     for occupation or use the rent or a fair proportion of it according to the
     nature and extent of the damage sustained shall be suspended until the
     Property (or the means of access to or egress from it) has been reinstated
     and made fit for occupation and use or until the end of three years from
     the date of the destruction or damage, whichever first occurs. Any dispute
     as to the amount of the proportion shall be referred to arbitration.  This
     sub-clause does not apply if and to the extent that the insurance monies in
     respect of loss of rent are wholly or partially irrecoverable solely or
     partly because of the act, default or omission of the Tenant or any person
     deriving title under the Tenant or any person at the Property with the
     express or implied authority of any of them.

(13) PREVENTION OF REINSTATEMENT

     The Landlord shall not be obliged to reinstate the Property in accordance
     with sub-clause (5) while prevented by a supervening event.  If the
     Landlord is unable to commence reinstatement within twenty four months from
     the date of destruction or damage because of a supervening event and the
     Property or a substantial part of it is unfit for occupation or use either
     party may determine the Term by serving notice on the other party at any
     time within six months of the end of the twenty four month period.  On
     service of the notice the Term will cease but without prejudice to any
     rights that any party may have against another for breach of any of their
     respective covenants or the conditions contained in this Lease and all
     insurance monies shall belong to the Landlord.

     In this sub-clause a supervening event means any of the following:

     (a)  inability of the Landlord to obtain the consents and permissions
          referred to in sub-clause (5) despite using all reasonable endeavours
          to do so;

     (b)  grant of any of the consents or permissions subject to a lawful
          condition with which it would be unreasonable to expect the Landlord
          to comply or the Landlord being requested as a precondition to
          obtaining any of the consents or permissions to enter into an
          agreement with the planning authority or any other authority
          containing conditions with which it would be unreasonable to expect
          the Landlord to comply;

     (c)  some defect in the site upon which reinstatement is to take place so
          that it could not be undertaken or could be undertaken only at a cost
          unacceptable to the Landlord (acting reasonably);

     (d)  inability of the Landlord to obtain access to the site to reinstate;

     (e)  prevention of reinstatement by any cause beyond the control of the
          Landlord.


10.  RE-ENTRY

(1)  If an Event of Default occurs then notwithstanding the waiver of any
     previous right of re-entry the Landlord may re-enter the Property or any
     part of it when the Term shall cease but without prejudice to any rights or
     remedies which may then have accrued to any party against another in
     respect of any antecedent breach (including the breach in respect of which
     re-entry is made) of any of the covenants or obligations contained in this
     Lease.

(2)  In this clause an Event of Default is any one of the following:

     (a)  the Rent or any part of it is in arrear and unpaid for seven Business
          Days after becoming payable (whether formally demanded or not); or

     (b)  a breach by the Tenant of any of the covenants by the Tenant in this
          Lease; or

                                     -33-
<PAGE>
 
     (c)  the Tenant (being a company) is deemed unable to pay its debts under
          section 123 of the Insolvency Act 1986 or the Tenant or any Guarantor
          (being a company) passes a resolution for winding-up or the directors
          of any of them present a petition for winding-up or an order for the
          winding-up of the Tenant or any Guarantor is made (other than (in any
          such case) a voluntary winding-up of a solvent company for the
          purposes of amalgamation or reconstruction) or the Tenant or any
          Guarantor is dissolved; or

     (d)  the Tenant (being a company) has an administrative or other receiver
          or a manager appointed of the whole or any part of its property or a
          petition is presented for an administration order or an administration
          order is made in respect of the Tenant or any Guarantor; or

     (e)  the Tenant (being a company) being registered as an unlimited company
          is re-registered as a limited company without the previous consent of
          the Landlord; or

     (f)  the Tenant (being an individual) presents a petition for a bankruptcy
          order to be made against him or a bankruptcy order is made against the
          Tenant or any Guarantor; or

          proposal is made or the Tenant (whether a company or an individual)
          enters into any kind of composition, scheme of arrangement, compromise
          or arrangement for the benefit of creditors or any class of creditors
          or permits or suffers any distress or execution to be levied on his
          goods; or

     (h)  there occurs in relation to the Tenant  in any country or territory in
          which any of them carries on business or to the jurisdiction of whose
          courts any of them or any of the property of any of them is subject to
          any event which corresponds in that country or territory with any of
          those mentioned in paragraphs (c) to (g) above or the Tenant
          otherwise becomes subject in any such country or territory to any law
          relating to insolvency, bankruptcy or winding up.


11.  GUARANTEE

     The Guarantor covenants with the Landlord in the terms set out in Schedule
     5 in respect of the period during which Exodus Internet Limited is bound by
     the Tenant's covenants and conditions in this Lease and any additional
     period during which Exodus Internet Limited is liable under an authorised
     guarantee agreement.


12.  VALUE ADDED TAX

(1)  If any VAT is chargeable on any supply made to the Tenant under the terms
     of this Lease, the Tenant shall pay by way of additional consideration the
     amount of that VAT and the Landlord shall provide a valid VAT invoice in
     relation to such VAT to the Tenant.

                                     -34-
<PAGE>
 
(2)  Without limiting sub-clause (1) above, each sum reserved or payable by the
     Tenant under the terms of this Lease is exclusive of VAT (if any) and is
     accordingly to be construed as a reference to that sum plus any VAT in
     respect of it, and where any sum is reserved as rent, the VAT is also
     reserved as rent.

(3)  If VAT is chargeable on any supply made by the Landlord to the Tenant for
     which a sum is not reserved or payable under the terms of this Lease, the
     Tenant shall pay that VAT to the Landlord against issue of a VAT invoice
     five Business Days before the Landlord has to pay the VAT to Customs.

(4)  Where under the terms of this Lease the Tenant is obliged:

     (a)  to make any payment to the Landlord or any other person (including,
          without limitation, by way of service charge, indemnity or
          reimbursement) by reference to any amount incurred or which will or
          may be incurred by the Landlord or any other person; or

     (b)  otherwise to pay all or part of the consideration for any supply made
          to the Landlord or any other person,

     then without prejudice to sub-clauses (1) to (3) above, the Tenant shall
     not be obliged to pay any amount in respect of VAT to the extent that it is
     recoverable by the Landlord or any other person as appropriate.

(5)  For the purposes of sub-clause (3) above, VAT is recoverable by a person,
     if that person (or any company treated as a member of the same VAT Group as
     that person) is entitled to credit for it as input tax under sections 25
     and 26 VATA 1994.  For the avoidance of doubt, VAT is not recoverable by a
     person only because he could elect to waive exemption, but has not done so.

(6)  Where for the purposes of this Lease it is necessary to calculate or
     estimate the cost or value of anything, including any building, structure,
     work, item, act or service, the cost or value shall be calculated or
     estimated so as to include any VAT which will or may be incurred in
     addition.

(7)  This clause shall not affect the generality of clause 6(3) (Outgoings).

(8)  Where the Tenant pays to the Landlord VAT in respect of any supply by the
     Landlord to the Tenant, the Landlord shall issue the Tenant with a proper
     VAT invoice in respect of that VAT.

(9)  If the Landlord wishes to make an election to waive the exemption in
     respect of the Property under paragraph 2 of Schedule 10, VATA 1994, the
     Landlord shall notify the Tenant, no less than 20 Business Days before the
     election is to take effect, of the election and the date on which it is
     intended to take effect.

(10) If for any reason the election referred to in sub-clause (9) above is
     validly revoked within three months after coming into effect, the Landlord
     shall repay to the Tenant any VAT paid by the Tenant, five Business Days
     after receipt by the Landlord from Customs of acknowledgement of the
     revocation.

          the time being of the Royal Institution of Chartered Surveyors in
          accordance with the Arbitration Acts 1950 to 1979 and 1996; and

     (b)  any dispute between the Tenant and any tenant or occupier of any other
          property owned or leased by the Landlord about any right in connection
          with the use of the Property and the other property or about any
          boundary structure separating the Property from the other property
          shall be determined by the Landlord acting reasonably.

(3)  COMPENSATION

                to the Tenant;

          (ii)  any damage caused to the Property by the possessions; and

                the End of Term.

     severed from the remainder of this Lease which shall remain in full force
     and effect.  In this sub-clause "provision" includes a clause, a sub-clause
     or a schedule or any part of any of them.

(12) PERPETUITY PERIOD

     (b)  will not be affected by:

          (i)    any time or indulgence granted to the Tenant by the Landlord;

          (ii)   any legal limitation, disability or other circumstances

                 in the terms of this Lease save as provided in section 18 of

                 or in part from the guarantee other than a release by deed
                 given by the Landlord.

3.   So long as this guarantee remains in force the Guarantor shall not:

          claim or prove as creditor in competition with the Landlord; or

4.   If the Landlord brings proceedings against the Tenant, the Guarantor shall
     be bound by any findings of fact, interim or final award or interlocutory
     or final judgment made by an arbitrator or the court in those proceedings
     in so far as the same relate to the subject matter of this Lease PROVIDED
     THAT the Landlord shall have served a copy of the writ summons petition or
     similar process which initiated such proceedings on the Guarantor before
     the expiry of 7 days after such proceedings were initiated.

     (a)  the Tenant (being a company) enters into liquidation and the
          liquidator disclaims this Lease; or

     (b)  the Tenant (being a company) is dissolved and the Crown disclaims this

     (c)  the Tenant (being an individual) becomes bankrupt and the trustee in

     (d)  this Lease is forfeited,

     then within six months after the disclaimer or forfeiture the Landlord may
     require the Guarantor by notice to accept a lease of the Property for a
     term equivalent to the residue which would have remained of the Term if
     there had been no disclaimer or forfeiture at the same rents and subject to
     the same covenants and conditions (including those as to the review of
     rent) as are reserved by and contained in this Lease (with the exception of
     this Schedule).

6.   The new lease and the rights and liabilities under it shall take effect as
     from the date of the disclaimer or forfeiture and the Guarantor shall be
     liable for all payments due under the new lease as from the date of
     disclaimer or forfeiture as if the new lease had been granted on the date
     of disclaimer or forfeiture.

7.   The Guarantor or his personal representatives shall pay the Landlord's
     costs of and accept the new lease and shall execute and deliver to the
     Landlord a counterpart of it.

8.   If the Landlord does not require the Guarantor to take a Lease of the
     Property, the Guarantor shall pay to the Landlord on demand a sum equal to
     the rent that would have been payable under this Lease but for the
     disclaimer or forfeiture in respect of the period from the date of the
     disclaimer or forfeiture until the date which is six months after the date
     of the disclaimer or forfeiture or the date on which the Property has been
     re-let by the Landlord, whichever first occurs.

9.   If any VAT is payable by the Tenant to the Landlord under the terms of the
     Lease, the Guarantor's obligation shall extend to that VAT. If the
     Guarantor makes any payment in respect of VAT, the Landlord's obligation to
     issue a VAT invoice to the Tenant under the Lease in respect of that VAT
     shall not be affected, and the Landlord shall not be under any obligation
     to issue a VAT invoice to the Guarantor in respect of that VAT.

          obligation to the Landlord or its predecessors in title to the
          Property carried out by and at the cost of the Tenant, its subtenants

          behalf thinks fit he may discharge the valuer and appoint another in

     Whenever reasonably required to do so by the Tenant and at the Tenant's
     cost, but not more often than twice a year, the Landlord shall produce to

     evidence of it and evidence of payment of the last premium.

(5)  REINSTATEMENT

     Subject to sub-clause (13) if the Property is destroyed or damaged by any
     of the Insured Risks, then unless the insurance is vitiated by any act,
     default or omission of the Tenant, any person deriving title under the
     Tenant or any person at the Property with the express or implied authority
     of any of them, the Landlord shall use reasonable endeavours to:

     (a)  obtain all consents and permissions necessary for reinstatement as
          soon as reasonably possible;
       
     (b)  subject to obtaining those consents and permissions, lay out as soon

     (c)  subject to the Tenant complying with its obligations in sub-clauses
          (6)(a)(iii), (7) and(9) make good out of the Landlord's own monies any

(6)  TENANT'S INSURANCE OBLIGATIONS

     (a)  The Tenant shall pay to the Landlord on demand:

          (i)  every premium payable by the Landlord (including any part of it
               which the Landlord is entitled to retain by way of commission)
               for insuring the Property in accordance with its obligations in
               sub-clause (1) and for effecting insurance in respect of
               liability to third parties including members of the public and
               such other insurances as the Landlord reasonably considers
               desirable;

          (ii) where the policy includes the Property and other properties, the
               proportion properly attributable to the Property of every premium
               payable by the Landlord (including any part of it which the
               Landlord is entitled to retain by way of commission) for insuring
               the Property and the other properties in accordance with its
               obligations in sub-clause (1) and for effecting (in relation to
               the Property and the other properties) the other insurances
               referred to in sub-paragraph (i), the proportion to be determined
               by the Landlord whose determination shall be conclusive save as
               to questions of law and save in case of manifest error;

                                     -30-
<PAGE>
 
          (iii)  the amount of any excess deducted or deductible by the insurers
                 on any claim made by the Landlord; and

          (iv)   all costs and expenses reasonably incurred by the Landlord in
                 obtaining a valuation of the Property for insurance purposes
                 (provided this is limited to one such valuation every two
                 years).

          All sums payable by the Tenant under paragraph (a)(i) shall be
          reserved as rent.

     (b)  The Tenant shall insure all plate glass in the Property against all
          risks with an insurance company approved by the Landlord in the joint
          names of the Landlord and the Tenant and, on demand, produce a copy of
          the insurance policy and evidence of payment of the last premium to
          the Landlord.

(7)  VITIATION

     The Tenant shall not use the Property or carry on any business at the
     Property or do or omit to do at the Property anything which may make void
     or voidable any policy for the insurance of the Property or any nearby
     property of the Landlord.

(8)  INCREASED PREMIUM

     The Tenant shall:

     (a)  not without the prior consent of the Landlord use the Property or
          carry on any business at the Property or do or omit to do at the
          Property anything which may increase the premium payable for the
          insurance; and
       
     (b)  if consent is given, repay on demand to the Landlord any resulting
          increased insurance premium payable by the Landlord.

(9)  IRRECOVERABLE REINSTATEMENT COST

     If the Property is destroyed or damaged by any of the Insured Risks and the
     insurance money under any insurance effected by the Landlord is wholly or
     partly irrecoverable because of any act, default or omission of the Tenant,
     any person deriving title under the Tenant or any person at the Property
     with the express or implied authority of any of them the Tenant shall pay
     to the Landlord within 14 days of written demand the whole or the
     appropriate proportion of the cost of reinstating the Property.  Any
     dispute as to the amount of such proportion shall be referred to
     arbitration.

(10) NOTICE OF DAMAGE

     If the Property is destroyed or damaged by any of the Insured Risks the
     Tenant shall give notice to the Landlord as soon as the destruction or
     damage comes to the notice of the Tenant.

                                     -31-
<PAGE>
 
(11) DOUBLE INSURANCE

     The Tenant shall not effect any insurance relating to the Property against
     any of the Insured Risks.  If the Tenant is entitled to the benefit of any
     insurance in respect of the Property, the Tenant shall pay to the Landlord
     all monies received by virtue of the insurance to enable the Landlord to
     apply them in making good the loss or damage in respect of which they have
     been received.

(12) CESSER OF RENT

     If the Property or any part of it (or the means of access to or egress from
     it) is destroyed or damaged by any of the Insured Risks so as to be unfit
     for occupation or use the rent or a fair proportion of it according to the
     nature and extent of the damage sustained shall be suspended until the
     Property (or the means of access to or egress from it) has been reinstated
     and made fit for occupation and use or until the end of three years from
     the date of the destruction or damage, whichever first occurs. Any dispute
     as to the amount of the proportion shall be referred to arbitration.  This
     sub-clause does not apply if and to the extent that the insurance monies in
     respect of loss of rent are wholly or partially irrecoverable solely or
     partly because of the act, default or omission of the Tenant or any person
     deriving title under the Tenant or any person at the Property with the
     express or implied authority of any of them.

(13) PREVENTION OF REINSTATEMENT

     The Landlord shall not be obliged to reinstate the Property in accordance
     with sub-clause (5) while prevented by a supervening event.  If the
     Landlord is unable to commence reinstatement within twenty four months from
     the date of destruction or damage because of a supervening event and the
     Property or a substantial part of it is unfit for occupation or use either
     party may determine the Term by serving notice on the other party at any
     time within six months of the end of the twenty four month period.  On
     service of the notice the Term will cease but without prejudice to any
     rights that any party may have against another for breach of any of their
     respective covenants or the conditions contained in this Lease and all
     insurance monies shall belong to the Landlord.

     In this sub-clause a supervening event means any of the following:

     (a)  inability of the Landlord to obtain the consents and permissions
          referred to in sub-clause (5) despite using all reasonable endeavours
          to do so;
       
     (b)  grant of any of the consents or permissions subject to a lawful
          condition with which it would be unreasonable to expect the Landlord
          to comply or the Landlord being requested as a precondition to
          obtaining any of the consents or permissions to enter into an
          agreement with the planning authority or any other authority
          containing conditions with which it would be unreasonable to expect
          the Landlord to comply;
       
     (c)  some defect in the site upon which reinstatement is to take place so
          that it could not be undertaken or could be undertaken only at a cost
          unacceptable to the Landlord (acting reasonably);

                                     -32-
<PAGE>
 
     (d)  inability of the Landlord to obtain access to the site to reinstate;
       
     (e)  prevention of reinstatement by any cause beyond the control of the
          Landlord.

10.  RE-ENTRY

(1)  If an Event of Default occurs then notwithstanding the waiver of any
     previous right of re-entry the Landlord may re-enter the Property or any
     part of it when the Term shall cease but without prejudice to any rights or
     remedies which may then have accrued to any party against another in
     respect of any antecedent breach (including the breach in respect of which
     re-entry is made) of any of the covenants or obligations contained in this
     Lease.

(2)  In this clause an Event of Default is any one of the following:

     (a)  the Rent or any part of it is in arrear and unpaid for seven Business
          Days after becoming payable (whether formally demanded or not); or
       
     (b)  a breach by the Tenant of any of the covenants by the Tenant in this
          Lease; or
       
     (c)  the Tenant (being a company) is deemed unable to pay its debts under
          section 123 of the Insolvency Act 1986 or the Tenant or any Guarantor
          (being a company) passes a resolution for winding-up or the directors
          of any of them present a petition for winding-up or an order for the
          winding-up of the Tenant or any Guarantor is made (other than (in any
          such case) a voluntary winding-up of a solvent company for the
          purposes of amalgamation or reconstruction) or the Tenant or any
          Guarantor is dissolved; or
       
     (d)  the Tenant (being a company) has an administrative or other receiver
          or a manager appointed of the whole or any part of its property or a
          petition is presented for an administration order or an administration
          order is made in respect of the Tenant or any Guarantor; or
       
     (e)  the Tenant (being a company) being registered as an unlimited company
          is re-registered as a limited company without the previous consent of
          the Landlord; or
       
     (f)  the Tenant (being an individual) presents a petition for a bankruptcy
          order to be made against him or a bankruptcy order is made against the
          Tenant or any Guarantor; or
       
     (g)  in relation to the Tenant (whether an individual or a company) a
          proposal is made or the Tenant (whether a company or an individual)
          enters into any kind of composition, scheme of arrangement, compromise
          or arrangement for the benefit of creditors or any class of creditors
          or permits or suffers any distress or execution to be levied on his
          goods; or
       
     (h)  there occurs in relation to the Tenant  in any country or territory in
          which any of them carries on business or to the jurisdiction of whose
          courts any of them or any of the property of any of them is subject to
          any event which corresponds in that country or 

                                     -33-
<PAGE>
 
          territory with any of those mentioned in paragraphs (c) to (g) above

          territory to any law relating to insolvency, bankruptcy or winding up.

11.  GUARANTEE

     The Guarantor covenants with the Landlord in the terms set out in Schedule
     5 in respect of the period during which Exodus Internet Limited is bound by
     the Tenant's covenants and conditions in this Lease and any additional
     period during which Exodus Internet Limited is liable under an authorised
     guarantee agreement.

12.  VALUE ADDED TAX

(1)  If any VAT is chargeable on any supply made to the Tenant under the terms
     of this Lease, the Tenant shall pay by way of additional consideration the
     amount of that VAT and the Landlord shall provide a valid VAT invoice in
     relation to such VAT to the Tenant.

(2)  Without limiting sub-clause (1) above, each sum reserved or payable by the
     Tenant under the terms of this Lease is exclusive of VAT (if any) and is
     accordingly to be construed as a reference to that sum plus any VAT in
     respect of it, and where any sum is reserved as rent, the VAT is also
     reserved as rent.

(3)  If VAT is chargeable on any supply made by the Landlord to the Tenant for
     which a sum is not reserved or payable under the terms of this Lease, the
     Tenant shall pay that VAT to the Landlord against issue of a VAT invoice
     five Business Days before the Landlord has to pay the VAT to Customs.

(4)  Where under the terms of this Lease the Tenant is obliged:

     (a)  to make any payment to the Landlord or any other person (including,
          without limitation, by way of service charge, indemnity or
          reimbursement) by reference to any amount incurred or which will or
          may be incurred by the Landlord or any other person; or
       
     (b)  otherwise to pay all or part of the consideration for any supply made
          to the Landlord or any other person,

     then without prejudice to sub-clauses (1) to (3) above, the Tenant shall
     not be obliged to pay any amount in respect of VAT to the extent that it is
     recoverable by the Landlord or any other person as appropriate.

(5)  For the purposes of sub-clause (3) above, VAT is recoverable by a person,
     if that person (or any company treated as a member of the same VAT Group as
     that person) is entitled to credit for it as input tax under sections 25
     and 26 VATA 1994.  For the avoidance of doubt, VAT is not recoverable by a
     person only because he could elect to waive exemption, but has not done so.

                                     -34-
<PAGE>
 
(6)  Where for the purposes of this Lease it is necessary to calculate or
     estimate the cost or value of anything, including any building, structure,
     work, item, act or service, the cost or value shall be calculated or
     estimated so as to include any VAT which will or may be incurred in
     addition.

(7)  This clause shall not affect the generality of clause 6(3) (Outgoings).

(8)  Where the Tenant pays to the Landlord VAT in respect of any supply by the
     Landlord to the Tenant, the Landlord shall issue the Tenant with a proper
     VAT invoice in respect of that VAT.

     respect of the Property under paragraph 2 of Schedule 10, VATA 1994, the
     Landlord shall notify the Tenant, no less than 20 Business Days before the
     election is to take effect, of the election and the date on which it is
     intended to take effect.

(10) If for any reason the election referred to in sub-clause (9) above is
     validly revoked within three months after coming into effect, the Landlord
     shall repay to the Tenant any VAT paid by the Tenant, five Business Days
     after receipt by the Landlord from Customs of acknowledgement of the
     revocation.

                 possessions have been sold by the Landlord in the mistaken
                 belief (which shall be presumed) that the possessions belonged
                 to the Tenant;
                 
          (ii)   any damage caused to the Property by the possessions; and

     that provision.

     Lease, the Guarantor's obligation shall extend to that VAT.  If the

<PAGE>
 
(7)  DISREGARDS

     The matters to be disregarded are:

          existence at the relevant Review Date of any improvement carried out

          obligation to the Landlord or its predecessors in title to the
          Property carried out by and at the cost of the Tenant, its subtenants
          or their respective predecessors in title during the Term or during
          any earlier period of occupation arising out of an agreement to grant
          the Term.

(8)  VALUER

     In the case of determination by a valuer:

     (a)  the fees and expenses of the valuer including the cost of his
          appointment shall be borne as he shall decide or in the absence of any
          decision equally by the Landlord and the Tenant who shall otherwise
          each bear their own costs;

     (b)  the valuer shall afford the Landlord and the Tenant an opportunity to
          make representations to him; and

     (c)  if the valuer dies, delays or becomes unwilling or incapable of acting
          or if for any other reason the president for the time being of the
          Royal Institution of Chartered Surveyors or the person acting on his
          behalf thinks fit he may discharge the valuer and appoint another in
          his place.

(9)  MEMORANDUM

     When the revised rent has been ascertained memoranda of it shall be signed
     by or on behalf of the Landlord and the Tenant and annexed to this Lease
     and the counterpart of it and the Landlord and the Tenant shall bear their
     own costs in respect of the memoranda.

(10) INTEREST

     If the revised rent payable with effect from any Review Date has not been
     agreed by that Review Date rent shall continue to be payable at the rate
     previously payable.  Forthwith on the revised rent being ascertained the
     Tenant shall pay to the Landlord any shortfall between the rent and the
     revised rent payable up to and on the preceding quarter day together with
     interest at the Interest Rate compounded quarterly on each part of the
     shortfall from the date or respective dates on which each part would have
     been due for payment had the revised rent been ascertained before the
     relevant Review Date until the date of payment.

                                      -7-

     fees and expenses of the valuer under sub-clause (8) within 15 Business
     Days of the same being demanded by the valuer the other shall be entitled
     to pay the same and the amount so paid shall be repaid on demand by the

     Time shall not be of the essence for the purposes of this clause 4.

          Year;

     Internal Area of the Property from time to time bears to the Gross Internal
     Area of the Lettable Areas at such time provided always that if the
     Landlord shall consider that having regard to the nature and degree of use
     by the Tenant or other tenants on the Estate of the facilities covered by
     the Gross Expenses or any other factors which the Landlord may reasonably
     consider relevant some other proportion ought properly to be payable by the
     Tenant the Landlord may substitute such other percentage as it shall
     consider reasonable either with regard to all or any items making up the
     Net Expenses provided that the proportion of the Net Expenses payable by
     the Tenant shall not be increased by reason solely or in part of any
     Lettable Areas being vacant or unlet.

     Landlord but at the cost of the Tenant adopt the course reasonably required
     by the Landlord for preventing the acquisition of the easement.

          revised rent are put forward to the third party at the same time as
          the representations of the Tenant and as though they were
          representations made by the Tenant; and

     (f)  procure that on any assignment of any underlease the outgoing
          undertenant enters into an authorised guarantee agreement and, where
          appropriate, guarantors enter into a contractual guarantee in each
          case with the landlord under the underlease in accordance with the
          provisions of the underlease.

     In paragraphs (c) to (f) of this sub-clause an underlease includes any
     lease where, by virtue of the grant of this Lease, the Tenant under this
     Lease becomes the holder of the immediate reversion to that lease.

(12) ASSOCIATED COMPANIES

     company which is a member of the same group as the Tenant (within the
     meaning of section 42 of the Landlord and Tenant Act 1954) for so long as
     both companies remain members of that group and provided that:

     (a)  no relationship of landlord and tenant is created between the two
          companies and no security of tenure is conferred upon the occupier;
          and

     shall keep the Property (other than plate glass and tenant's or trade
     fixtures) insured with insurers or underwriters selected by the Landlord in

     The insurance shall extend to:

     (a)  architects' and other professional fees in relation to the

     (b)  the costs of demolition and removal of debris; and

     (c)  loss of rent for such period as the Landlord may decide in an amount

          increases in rent.

(4)  PRODUCTION OF POLICY

     Whenever reasonably required to do so by the Tenant and at the Tenant's
     cost, but not more often than twice a year, the Landlord shall produce to

     evidence of it and evidence of payment of the last premium.

(5)  REINSTATEMENT

          (6)(a)(iii), (7) and (9) make good out of the Landlord's own monies

          or excess imposed by the insurers).

(6)  TENANT'S INSURANCE OBLIGATIONS

     (a)  The Tenant shall pay to the Landlord on demand:

          (i)   every premium payable by the Landlord (including any part of it
                which the Landlord is entitled to retain by way of commission)
                for insuring the Property in accordance with its obligations in
                sub-clause (1) and for effecting insurance in respect of
                liability to third parties including members of the public and
                such other insurances as the Landlord reasonably considers
                desirable;

          (ii)  where the policy includes the Property and other properties, the
                proportion properly attributable to the Property of every
                premium payable by the Landlord (including any part of it which
                the Landlord is entitled to retain by way of commission) for
                insuring the Property and the other properties in accordance
                with its obligations in sub-clause (1) and for effecting (in
                relation to the Property and the other properties) the other
                insurances referred to in sub-paragraph (i), the proportion to
                be determined by the Landlord whose determination shall be
                conclusive save as to questions of law and save in case of
                manifest error;

          (iii) the amount of any excess deducted or deductible by the insurers
                on any claim made by the Landlord; and

          (iv)  all costs and expenses reasonably incurred by the Landlord in
                obtaining a valuation of the Property for insurance purposes
                (provided this is limited to one such valuation every two
                years).

          All sums payable by the Tenant under paragraph (a)(i) shall be
          reserved as rent.

     (b)  The Tenant shall insure all plate glass in the Property against all
          risks with an insurance company approved by the Landlord in the joint
          names of the Landlord and the Tenant and, on demand, produce a copy of
          the insurance policy and evidence of payment of the last premium to
          the Landlord.

(7)  VITIATION

     The Tenant shall not use the Property or carry on any business at the
     Property or do or omit to do at the Property anything which may make void

     property of the Landlord.

                                     -29-
<PAGE>
 
(8)  INCREASED PREMIUM

     The Tenant shall:

     (a)  not without the prior consent of the Landlord use the Property or
          carry on any business at the Property or do or omit to do at the
          Property anything which may increase the premium payable for the
          insurance; and

     (b)  if consent is given, repay on demand to the Landlord any resulting
          increased insurance premium payable by the Landlord.

(9)  IRRECOVERABLE REINSTATEMENT COST

     If the Property is destroyed or damaged by any of the Insured Risks and the
     insurance money under any insurance effected by the Landlord is wholly or
     partly irrecoverable because of any act, default or omission of the Tenant,
     any person deriving title under the Tenant or any person at the Property
     with the express or implied authority of any of them the Tenant shall pay
     to the Landlord within 14 days of written demand the whole or the
     appropriate proportion of the cost of reinstating the Property.  Any
     dispute as to the amount of such proportion shall be referred to
     arbitration.

(10) NOTICE OF DAMAGE

     If the Property is destroyed or damaged by any of the Insured Risks the
     Tenant shall give notice to the Landlord as soon as the destruction or
     damage comes to the notice of the Tenant.

(11) DOUBLE INSURANCE

     The Tenant shall not effect any insurance relating to the Property against
     any of the Insured Risks.  If the Tenant is entitled to the benefit of any
     insurance in respect of the Property, the Tenant shall pay to the Landlord
     all monies received by virtue of the insurance to enable the Landlord to
     apply them in making good the loss or damage in respect of which they have
     been received.

(12) CESSER OF RENT

     If the Property or any part of it (or the means of access to or egress from
     it) is destroyed or damaged by any of the Insured Risks so as to be unfit
     for occupation or use the rent or a fair proportion of it according to the
     nature and extent of the damage sustained shall be suspended until the
     Property (or the means of access to or egress from it) has been reinstated
     and made fit for occupation and use or until the end of three years from
     the date of the destruction or damage, whichever first occurs. Any dispute
     as to the amount of the proportion shall be referred to arbitration.  This
     sub-clause does not apply if and to the extent that the insurance monies in
     respect of loss of rent are wholly or partially irrecoverable solely or
     partly because of the act, default or omission of the Tenant or any person
     deriving title under the Tenant or any person at the Property with the
     express or implied authority of any of them.

(13) PREVENTION OF REINSTATEMENT

     The Landlord shall not be obliged to reinstate the Property in accordance
     with sub-clause (5) while prevented by a supervening event.  If the
     Landlord is unable to commence 

                                     -30-
<PAGE>
 
     reinstatement within twenty four months from the date of destruction or
     damage because of a supervening event and the Property or a substantial
     part of it is unfit for occupation or use either party may determine the
     Term by serving notice on the other party at any time within six months of
     the end of the twenty four month period. On service of the notice the Term
     will cease but without prejudice to any rights that any party may have
     against another for breach of any of their respective covenants or the
     conditions contained in this Lease and all insurance monies shall belong to
     the Landlord.

     In this sub-clause a supervening event means any of the following:

     (a)  inability of the Landlord to obtain the consents and permissions
          referred to in sub-clause (5) despite using all reasonable endeavours
          to do so;

     (b)  grant of any of the consents or permissions subject to a lawful
          condition with which it would be unreasonable to expect the Landlord
          to comply or the Landlord being requested as a precondition to
          obtaining any of the consents or permissions to enter into an
          agreement with the planning authority or any other authority
          containing conditions with which it would be unreasonable to expect
          the Landlord to comply;

     (c)  some defect in the site upon which reinstatement is to take place so
          that it could not be undertaken or could be undertaken only at a cost
          unacceptable to the Landlord (acting reasonably);

     (d)  inability of the Landlord to obtain access to the site to reinstate;

     (e)  prevention of reinstatement by any cause beyond the control of the
          Landlord.


10.  RE-ENTRY

(1)  If an Event of Default occurs then notwithstanding the waiver of any
     previous right of re-entry the Landlord may re-enter the Property or any
     part of it when the Term shall cease but without prejudice to any rights or
     remedies which may then have accrued to any party against another in
     respect of any antecedent breach (including the breach in respect of which
     re-entry is made) of any of the covenants or obligations contained in this
     Lease.

(2)  In this clause an Event of Default is any one of the following:

     (a)  the Rent or any part of it is in arrear and unpaid for seven Business

          Lease; or

     (c)  the Tenant (being a company) is deemed unable to pay its debts under
          section 123 of the Insolvency Act 1986 or the Tenant or any Guarantor
          (being a company) passes a resolution for winding-up or the directors
          of any of them present a petition for winding-up or an order for the
          winding-up of the Tenant or any Guarantor is made (other than (in any
          such case) a voluntary winding-up of a solvent company for the
          purposes of amalgamation or reconstruction) or the Tenant or any
          Guarantor is dissolved; or

                                     -31-
<PAGE>
 
     (d)  the Tenant (being a company) has an administrative or other receiver
          or a manager appointed of the whole or any part of its property or a
          petition is presented for an administration order or an administration
          order is made in respect of the Tenant or any Guarantor; or

     (e)  the Tenant (being a company) being registered as an unlimited company

          order to be made against him or a bankruptcy order is made against the

          proposal is made or the Tenant (whether a company or an individual)
          enters into any kind of composition, scheme of arrangement, compromise
          or arrangement for the benefit of creditors or any class of creditors
          or permits or suffers any distress or execution to be levied on his
          goods; or

     (h)  there occurs in relation to the Tenant in any country or territory in
          which any of them carries on business or to the jurisdiction of whose

          any event which corresponds in that country or territory with any of
          those mentioned in paragraphs (c) to (g) above or the Tenant otherwise
          becomes subject in any such country or territory to any law relating
          to insolvency, bankruptcy or winding up.


11.  GUARANTEE

     The Guarantor covenants with the Landlord in the terms set out in Schedule
     5 in respect of the period during which Exodus Internet Limited is bound by
     the Tenant's covenants and conditions in this Lease and any additional
     period during which Exodus Internet Limited is liable under an authorised
     guarantee agreement.


12.  VALUE ADDED TAX

(1)  If any VAT is chargeable on any supply made to the Tenant under the terms
     of this Lease, the Tenant shall pay by way of additional consideration the
     amount of that VAT and the Landlord shall provide a valid VAT invoice in
     relation to such VAT to the Tenant.

(2)  Without limiting sub-clause (1) above, each sum reserved or payable by the
     Tenant under the terms of this Lease is exclusive of VAT (if any) and is
     accordingly to be construed as a reference to that sum plus any VAT in
     respect of it, and where any sum is reserved as rent, the VAT is also
     reserved as rent.

(3)  If VAT is chargeable on any supply made by the Landlord to the Tenant for
     which a sum is not reserved or payable under the terms of this Lease, the
     Tenant shall pay that VAT to the Landlord against issue of a VAT invoice
     five Business Days before the Landlord has to pay the VAT to Customs.

(4)  Where under the terms of this Lease the Tenant is obliged:

                                     -32-
<PAGE>
 
     (a)  to make any payment to the Landlord or any other person (including,
          without limitation, by way of service charge, indemnity or
          reimbursement) by reference to any amount incurred or which will or
          may be incurred by the Landlord or any other person; or

     (b)  otherwise to pay all or part of the consideration for any supply made
          to the Landlord or any other person,

     then without prejudice to sub-clauses (1) to (3) above, the Tenant shall
     not be obliged to pay any amount in respect of VAT to the extent that it is
     recoverable by the Landlord or any other person as appropriate.

(5)  For the purposes of sub-clause (3) above, VAT is recoverable by a person,
     if that person (or any company treated as a member of the same VAT Group as
     that person) is entitled to credit for it as input tax under sections 25
     and 26 VATA 1994.  For the avoidance of doubt, VAT is not recoverable by a
     person only because he could elect to waive exemption, but has not done so.

(6)  Where for the purposes of this Lease it is necessary to calculate or
     estimate the cost or value of anything, including any building, structure,
     work, item, act or service, the cost or value shall be calculated or
     estimated so as to include any VAT which will or may be incurred in
     addition.

(7)  This clause shall not affect the generality of clause 6(3) (Outgoings).

(8)  Where the Tenant pays to the Landlord VAT in respect of any supply by the
     Landlord to the Tenant, the Landlord shall issue the Tenant with a proper

     respect of the Property under paragraph 2 of Schedule 10, VATA 1994, the
     Landlord shall notify the Tenant, no less than 20 Business Days before the
     election is to take effect, of the election and the date on which it is
     intended to take effect.

(10) If for any reason the election referred to in sub-clause (9) above is
     validly revoked within three months after coming into effect, the Landlord
     shall repay to the Tenant any VAT paid by the Tenant, five Business Days
     after receipt by the Landlord from Customs of acknowledgement of the
     revocation.

          accordance with the Arbitration Acts 1950 to 1979 and 1996; and

     (b)  any dispute between the Tenant and any tenant or occupier of any other
          property owned or leased by the Landlord about any right in connection

          boundary structure separating the Property from the other property

3.   The Guarantor is liable to the Landlord under this guarantee as sole or
     principal debtor and the obligations of the Guarantor under this guarantee
     constitute a direct, primary and unconditional liability to pay on demand
     to the Landlord any sum which the Assignee is liable to pay under this

     to the review of rent) as are reserved by and contained in this Lease.

5.   The new lease and the rights and liabilities under it shall take effect as

6.   The Guarantor shall pay the Landlord's costs of and accept the new lease
     and shall execute and deliver to the Landlord a counterpart of it.

     the date which is six months after the date of the disclaimer or the date
     on which the Property has been re-let by the Landlord, whichever first
     occurs.

9.   To the extent that any provision of this guarantee does not conform with
     section 16 of the Act, that provision shall be severed from the remainder
     of this guarantee and this guarantee shall have effect as if it excluded
     that provision.

10   If any VAT is payable by the Tenant to the Landlord under the terms of the
     Lease, the Guarantor's obligation shall extend to that VAT.  If the
     Guarantor makes any payment in respect of VAT, the Landlord's obligation to
     issue a VAT invoice to the Assignee under the Lease in respect of that VAT

         and provided always the Tenant has paid to the Landlord all sums set
         out as in Clause 4 above (failing which the Landlord may deduct such

                   of the Landlord) and on completion of such deed transfer the
                   balance of the Deposit to such account as shall have been
                   opened by the transferee (after the deduction of any sum

                   determination (by agreement) of the term granted by the Lease
                   or its determination in consequence of the exercise by the
                   Tenant of any option to determine conferred on it by the
                   Lease
<PAGE>
 
               and in either case vacant possession of the premises demised by
               the Lease being given to the Landlord; or

     6.1.2     the Tenant demonstrating that it has made Net Profits for each of
               the immediately preceding Years of Account at least equal to

               of Account it has a Net Asset Value of not less than five times
               the Rental Liability

     and provided always the Tenant has paid to the Landlord all sums set out as
     in Clause 4 above (failing which the Landlord may deduct such sums as are
     properly due from the Deposit) the Landlord shall then release the balance
     to the Tenant within 5 working days of receipt of a written request from
     the Tenant for such release

6.2  The Tenant may demonstrate that it satisfies the requirements of Clause
     6.1.2 by means of audited accounts or by means of such other evidence as
     shall be reasonably acceptable to the Landlord

     Account which yields the best rate of interest reasonably obtainable from
     the Bank having regard to the provisions of this Deed

     first instance shall be used in or towards payment of any sums payable by

     such interest (less tax properly deducted) shall be paid to the Tenant on
     an annual basis

7.3  All tax payable in respect of interest accruing on the Deposit shall be
     paid by the Tenant from its own money


8.   MISCELLANEOUS

     It is hereby agreed and declared that:

     8.1       The existence of the Deposit shall not prejudice the Landlord's
               ability to proceed against the Tenant for any breach of any
               covenant agreement or condition on the part of the Tenant under
               the Lease or entitle the Tenant to withhold any moneys or fail to

               the Deposit shall not be regarded as an advance payment of rent

     8.2       The proviso for re-entry contained in the Lease shall be
               exercisable as well upon any breach of any covenant or obligation
               on the part of the Tenant contained in this Deed as on the

              being substituted for the name of the Landlord) and

       5.1.2  the Landlord shall procure that any transferee enters into a rent
              deposit deed with the Tenant in identical terms to this Deed (but
              with the transferee's name substituted for the name of the
              Landlord) and on completion of such deed transfer the balance of
              the Deposit to such account as shall have been opened by the
              transferee (after the deduction of any sum withdrawn pursuant to
              Clause 4 above) and upon serving notice of such transfer on the
              Tenant shall forthwith be released automatically from any further
              liability under the terms of this Deed

              (by agreement) of the term granted by the Lease or its
              determination in consequence of the exercise by the Tenant of any
              option to determine conferred on it by the Lease and in either
              case vacant possession of the premises demised by the Lease being
              given to the Landlord; or

       6.1.2  the Tenant demonstrating that it has made Net Profits for each of
              the immediately preceding Years of Account at least equal to three
              times the Rental Liability and that in each of those Years of
              Account it has a Net Asset Value of not less than five times the
              Rental Liability

       and provided always the Tenant has paid to the Landlord all sums set out
       as in Clause 4 above (failing which the Landlord may deduct such sums as
       are properly due from the Deposit) the Landlord shall then release the
       balance to the Tenant within 5 working days of receipt of a written
       request from the Tenant for such release

6.2    The Tenant may demonstrate that it satisfies the requirements of Clause
       6.1.2 by means of audited accounts or by means of such other evidence as
       shall be reasonably acceptable to the Landlord

7.     INTEREST

       Account which yields the best rate of interest reasonably obtainable from
       the Bank having regard to the provisions of this Deed

       subject thereto such interest (less tax properly deducted) shall be paid
       to the Tenant on an annual basis

7.3    All tax payable in respect of interest accruing on the Deposit shall be
       paid by the Tenant from its own money

8.     MISCELLANEOUS

       It is hereby agreed and declared that:

       8.1    The existence of the Deposit shall not prejudice the Landlord's
              ability to proceed against the Tenant for any breach of any
              covenant agreement or condition on the 

                                      -6-

              withhold any moneys or fail to perform any covenant agreement or

              an advance payment of rent

8.2           The proviso for re-entry contained in the Lease shall be
              exercisable as well upon any breach of any covenant or obligation
              on the part of the Tenant contained in this Deed as on the
              happening of any of the events mentioned in the Lease

8.3           The rights of the Landlord under this Deed do not limit its rights

     Notwithstanding the foregoing to the contrary, in the event that Landlord

not to terminate this Amendment and the Amendment shall remain in full force and
effect.

     5.   EXTENSION OF TERM.  Landlord and Tenant hereby acknowledge and agree
          -----------------                                                   
that the term of the Lease (prior to the Lease being amended by this Amendment)
as to the Existing Premises expires on April 30, 2001. Landlord and Tenant

($15,708.00) on deposit with Landlord shall be increased by Tenant by an
additional Thirty-Eight Thousand One Hundred Twelve and 00/100ths Dollars
($38,112.00) ("Additional Cash Security Deposit"). The existing Letter of Credit
Security Deposit in the amount of One Hundred Thirty-Eight Thousand and
00/100ths Dollars ($138,000.00) on deposit with Landlord shall be replaced by
Tenant with a Letter of Credit Security Deposit in the amount of Two Hundred
Seventy-Six Thousand and 00/100ths Dollars ($276,000.00) ("Increased Letter of
Credit Security Deposit"). The Increased Letter of Credit Security Deposit shall

          B.   AMENDMENT TO PARAGRAPH 7.  The third and fourth sentences of
               ------------------------

Rent or other sum in default, the repair of such damage to the Premises or the

                           FIRST AMENDMENT OF LEASE


     This First Amendment of Lease ("Amendment") is entered into by and between
David A. Sabey and Sandra L. Sabey, Husband and Wife  ("Landlord"), as Landlord
and Exodus Communications, Inc, a Delaware corporation ("Tenant"), as Tenant,
under that certain Lease ("Lease"), dated December 4, 1998, between the parties
hereto.

                                R E C I T A L S
                                - - - - - - - -

     A.   Landlord and Tenant desire to expand the Premises to include the third
floor of the Building and to provide for certain other amendments to the Lease.

     B.   Except as may be expressly provided otherwise in this Amendment,
capitalized terms in this Amendment shall have the meaning given such terms in
the Lease.

     NOW, THEREFORE, Landlord and Tenant agree as follows:
 
1.   Amendments.
     ---------- 

          1.1  Section 1.3 of the Lease is amended and restated in its entirety
to read as follows:

          1.3  PREMISES.  The "Premises" shall mean the space consisting of
approximately 99,288 net rentable square feet located on the first, second and
third floors of the Building, including 6,195 square feet in the annex building
and the 710 non-rentable square foot loading dock, which are depicted on the
floor plan attached to this Lease as Exhibit B, subject to recalculation in
accordance with Section 2. The loading dock shall be free of Rent during the
Term of this Lease. Landlord shall deliver the annex building of 6,195 rentable
s.f., the loading dock and approximately 28,500 net rentable square feet of
office space/data center to Tenant on February 1, 1999. Landlord shall pay a
penalty of Five Thousand Dollars ($5,000) to Tenant for each day that it delays
delivery of at least 25,000 net rentable square feet of office space/data
center, subject to Tenant's timely approvals and decisions, after March 1, 1999.
Approximately 32,593 net rentable square feet of additional space shall be
delivered to Tenant on June 1, 1999 and the remaining approximately 32,000 net
rentable square feet located on the third floor of the Building shall be
delivered June 1, 2000. The Premises shall include the tenant improvements, if
any, described in Exhibit C.

          1.2  Section 1.4 of the Lease is amended and restated in its entirety
to read as follows:

          1.4  TENANT'S SHARE. "Tenant's Share" shall mean "Tenant's Share of
the Building" or "Tenant's Share of the Property," as applicable. "Tenant's

                                       1
<PAGE>
 
Share of the Building" shall initially mean thirty-four and ninety-three one
hundredths percent (34.93%). "Tenant's Share of the Property" shall initially
mean fourteen and fifty-five one hundredths percent (14.55%). Commencing on the
earlier of June 1, 1999 or the date on which Tenant first occupies all or any
portion of the remaining 32,593 net rentable square feet of office space/data
center located on the second floor, "Tenant's Share of the Building" shall
automatically be increased to sixty-seven and seventy-eight one hundredths
percent (67.78%) and "Tenant's Share of the Property" shall be automatically
increased to twenty-eight and twenty-one one hundredths percent (28.21%). The
earlier of: (i) the date that Tenant occupies the third floor space for purposes
other than build-out or (ii) June 1, 2000, "Tenant's Share of the Building"
shall automatically be increased to one hundred percent (100%) and "Tenant's
Share of the Property" shall be automatically increased to forty-one and sixty-
three one hundredths percent (41.63%). "Tenant's Share of the Building" is
calculated by dividing the net rentable area of the Premises by the net rentable
area of the Building (approximately 99,288 net rentable square feet). "Tenant's
Share of the Property" is calculated by dividing the net rentable area of the
Premises by the net rentable area of the Property (approximately 238,540 net
rentable square feet). In the event the rentable area of the Premises or
Building is altered or recalculated in accordance with Section 2, Landlord shall
adjust Tenant's Share of the Building to properly reflect such event. Landlord's
adjustment of such Tenant's Share shall be final.

          1.3  Section 1.9 of the Lease is amended and restated in its entirety
to read as follows:

          1.9  BASE RENT. "Base Rent" from the Commencement Date through May 31,
1999 shall mean the net rentable square feet of the first floor multiplied by
$10.25 per square foot per year, based on 34,695 rentable square feet of
Premises (Twenty-nine Thousand Six Hundred Thirty-five and 31/100 Dollars
($29,635.31) per month). "Base Rent" from June 1, 1999 through May 31, 2001
shall mean 67,288 net rentable square feet of Premises multiplied by $10.25 per
square foot per year, (Fifty-seven Thousand Four Hundred Seventy-five and 17/100
Dollars ($57,475.17) per month). Notwithstanding the foregoing, the earlier of:
(i) the date Tenant occupies the third floor space for other than build-out or
(ii) June 1, 2000, "Base Rent" from such date through May 31, 2001 shall be
increased to include the net rentable square feet of 32,000 multiplied by $10.50
per square foot per year for an additional Twenty-eight Thousand and 00/100
Dollars ($28,000.00) per month. "Base Rent" from June 1, 2001 through May 31,
2004 shall mean the net rentable square feet of 67,288 multiplied by $11.25 per
square foot per year and the net rentable square feet of 32,000 multiplied by
$11.50 (Ninety-three Thousand Seven Hundred Forty-nine and 17/100 Dollars
($93,749.17) per month). "Base Rent" from June 1, 2004 through May 31, 2006
shall mean the net rentable square feet of 67,288 multiplied by $12.50 per
square foot per year and the net rentable square feet of 32,000 multiplied by
$12.75 per square foot per year (One Hundred-four Thousand Ninety-one and 67/100
Dollars ($104,091.67) per month). "Base Rent" from June 1, 2006 through May 31,
2009 shall mean the net rentable square feet of 67,288 multiplied by $13.50 per
square foot per year and the net rentable square feet of 32,000 multiplied by
$13.75 per square foot per year, (One Hundred-twelve Thousand Three Hundred
Ninety-five and 67/100 Dollars ($112,365.67)

                                       2
<PAGE>
 
per month). Prior to the Commencement Date, the net rentable square feet shall
be recalculated in accordance with Section 2. Base Rent shall be payable as
provided in Section 4.

     1.4  Section 1.10 of the Lease is amended and restated in its entirety to
read as follows:

          1.10 EARLY OCCUPANCY. Tenant will be allowed to occupy any square
footage on the first and second floors of the Premises they feel is ready for
occupancy before the Commencement Date, or any square footage on the third floor
of the Premises before June 1, 2000. Early Occupancy shall mean any use of the
space not directly related to the installation of equipment or constructing the
Premises. "Base Rent" for space located on the first and second floors of the
Premises will be calculated by multiplying the actual occupied rentable square
feet by $10.25 per net rentable square foot and "Base Rent" for space located on
the third floor of the Premises will be calculated by multiplying the actual
occupied rentable square feet by $10.50 per net rentable square foot. Tenant
will be responsible for all "Additional Rent" as described in Section 8 on the
portion of the space that they occupy early.

          1.5  Section 15.1 of the Lease is amended by adding the following to
the end of such Section:

     Notwithstanding the foregoing, Landlord hereby grants Tenant the right to
sublease all or a portion of the 32,000 net rentable square feet of Premises
located on the third floor of the Building; however, if the Rent that Tenant
charges to a sublessee is more than the Base Rent Tenant is paying on such
subleased Premises under this Lease, Tenant agrees to share fifty percent (50%)
of such additional amount with Landlord, which amount shall be paid to Landlord
on a monthly basis as Additional Rent throughout the term of the sublease.

     2.   Entire Amendment.  This Amendment sets forth the entire agreement of
          ----------------                                                    
the parties with respect to the subject matter set forth herein and may not be
modified other than by an agreement in writing signed by the parties hereto or
their respective successors and interests.

     3.   Exhibit.  Exhibit B-3 is attached hereto and incorporated herein by
          -------                                                            
this reference.

     4.   Acknowledgment.  The parties hereto each acknowledge that except as
          --------------                                                     
expressly modified by this Amendment, all the terms and conditions of the Lease
remain unchanged and are in full force and effect and enforceable in accordance
with their terms.  In the event of a conflict between the Lease and this
Amendment, the terms and provisions of this Amendment shall control.
