                                  THE COMPANY
 
  Exodus is a leading provider of Internet system and network management
solutions for enterprises with mission-critical Internet operations. The
Company's solutions include server hosting, Internet connectivity,
collaborative management and Internet technology services, which together
provide the high performance, scalability and expertise that enterprises need
to optimize their Internet operations. The Company delivers its services from
geographically distributed, state-of-the-art Internet Data Centers that are
connected through a redundant high performance dedicated backbone ring. The
Company's tailored solutions are designed to be seamlessly integrated with
existing enterprise systems architectures and enable customers to outsource the
monitoring, administration and optimization of their equipment, applications
and overall Internet operations. As of December 31, 1997, the Company had over
180 Internet Data Center customers and managed over 2,000 customer servers. The
Company's customers range from pioneering Internet-based businesses to Fortune
500 enterprises and include companies such as Computer Associates
International, Inc., GeoCities, Hewlett-Packard Company, Hotmail Corporation,
Inktomi Corporation, National Semiconductor Corporation, PC World
Communications, Inc., Software.net and USAToday Information Network.
 
  Use of the Internet, including intranets and extranets, has grown rapidly in
recent years. As this use continues to grow, enterprises are increasing the
breadth and depth of their Internet product and service offerings. These
Internet operations are mission-critical for virtually all Internet-based
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 geographically distributed
state-of-the-art facilities and networks that are monitored and managed 24x7 by
experts in Internet technology, can be upgraded to reflect changing
technologies and can be scaled as the needs of enterprises evolve. However,
such a continuing significant investment of resources is often an inefficient
use of enterprises' overall resources. As a result, corporate IT departments
are increasingly seeking collaborative outsourcing arrangements that can
increase performance, provide continuous operation of their Internet solutions
and reduce Internet operating expenses. Exodus believes a significant
opportunity exists for a highly-focused company to provide a combination of
server hosting, Internet connectivity, collaborative management and Internet
technology services that will enable reliable, high performance of enterprises'
mission-critical Internet operations.
 
  The Company's Internet system and network management solutions are based on a
core set of server hosting and Internet connectivity services, which are
enhanced by a growing number of collaborative management and Internet
technology services. The Company's Internet Data Centers
 
                                       3
<PAGE>
 
provide a secure platform for server hosting 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. The Company's national backbone ring of multiple high-speed, clear-
channel DS-3 lines and private and public network peering interconnections
provide the foundation for the Company's high performance, scalable Internet
connectivity services. The Company's collaborative management services,
including performance monitoring and site management reports, enable customers
and the Company to manage customers' Internet operations jointly, proactively
and continuously. Finally, the Company's Internet technology services,
including security and content distribution, integrate best-of-breed
technologies of leading vendors with the Company's expertise to provide
customers with scalable, secure and high performing Internet applications. The
Company's portfolio of layered services optimize the development, deployment
and proactive management of enterprises' mission-critical Internet operations.
 
  The Company began offering server hosting services in late 1995, opened its
first dedicated Internet Data Center in August 1996 and introduced its
collaborative management and Internet technology services in 1997. The Company
currently operates six Internet Data Centers, consisting of approximately
90,000 gross square feet, located in five metropolitan areas: Los Angeles, New
York, San Francisco, Seattle and Washington, D.C. The Company intends to expand
domestically and internationally, including the expected addition of an
additional Internet Data Center in the San Francisco metropolitan area and a
new site in the London metropolitan area in the first half of 1998.
 
  The Company's objective is to become the leading provider of Internet system
and network management solutions for enterprises with mission-critical Internet
operations. The key elements of this strategy include (i) extending the
Company's market leadership, (ii) focusing on the development of new
collaborative management services, (iii) expanding domestically and
internationally by adding Internet Data Centers, (iv) leveraging the Company's
significant expertise to address new market opportunities such as e-commerce
and extranets and (v) establishing strategic relationships with leading
technology developers and distribution alliances with content developers,
system integrators, system vendors, consulting companies and ISPs.
 
  The Company is the successor to a Maryland corporation that was formed in
August 1992 and reincorporated in California in May 1995. The Company will
reincorporate in Delaware prior to the closing of this offering. Unless the
context otherwise requires, the term "Company" or "Exodus" refers to Exodus
Communications, Inc. and its California and Maryland predecessors. The
Company's principal executive offices are located at 2650 San Tomas Expressway,
Santa Clara, California 95051. The Company's telephone number is (408) 346-
2200.

                         SUMMARY FINANCIAL INFORMATION
 
  The following summary financial information should be read in conjunction
with the Company's Financial Statements and Notes thereto and "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
included elsewhere in this Prospectus. The summary financial information for
the years ended December 31, 1995 and 1996 and for the nine months ended
September 30, 1997, and as of September 30, 1997, is derived from financial
statements of the Company that have been audited by KPMG Peat Marwick LLP,
independent auditors. The summary financial information for the nine months
ended September 30, 1996 is derived from unaudited financial statements that
have been prepared by the Company on substantially the same basis as the
audited 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 period. Historical
results are not necessarily indicative of the results to be expected in the
future and results of interim periods are not necessarily indicative of results
for the entire year.

                                 RISK FACTORS
 
  This offering involves a high degree of risk. In addition to the other
information set forth in this Prospectus, the following risk factors should be
considered carefully in evaluating the Company and its business before
purchasing any of the shares of Common Stock of the Company. This Prospectus
contains certain forward-looking statements that involve risks and
uncertainties, such as statements of the Company's plans, objectives,
expectations and intentions. The cautionary statements made in this Prospectus
should be read as being applicable to all related forward-looking statements
wherever they appear in this Prospectus. The Company's actual results could
differ materially from those discussed in this Prospectus. Factors that could
cause or contribute to such differences include those discussed below, as well
as those discussed elsewhere in this Prospectus.
 
LIMITED OPERATING HISTORY; HISTORY OF LOSSES
 
  While the Company began operations in 1992, it did not offer server hosting
services until 1995 and did not open its first dedicated Internet Data Center
until August 1996, at which time it refocused its business strategy on
providing Internet system and network management solutions for enterprises'
mission-critical Internet operations. As a result, the Company's business
model is still in an emerging state. Since it began to offer server hosting
services in 1995, the Company has experienced operating losses and negative
cash flows from operations each quarterly and annual period. As of September
30, 1997, the Company had an accumulated deficit of approximately $20.7
million. The revenue and income potential of the Company's business and market
is unproven, and the Company's limited operating history makes an evaluation
of the Company and its prospects difficult. Currently, the Company anticipates
making significant investments in new Internet Data Centers and product
development and sales and marketing programs and personnel and therefore
believes that it will continue to experience net losses on a quarterly and
annual basis for the foreseeable future. The Company and its prospects must be
considered in light of the risks, expenses and difficulties encountered by
companies in the new and rapidly evolving market for Internet system and
network management solutions. To address these risks, among other things, the
Company must market its brand name effectively, provide scalable, reliable and
cost-effective services, continue to grow its infrastructure to accommodate
new Internet Data Centers and increased bandwidth use of its network, expand
its channels of distribution, retain and motivate qualified personnel and
continue to respond to competitive developments. Failure of the Company's
services to achieve market acceptance would have a material adverse effect on
the Company's business, results of operations and financial condition.
Although the Company has experienced significant growth in revenues in recent
periods, the Company does not believe that this growth rate necessarily is
indicative of future operating results, and there can be no assurance that the
Company will ever achieve profitability on a quarterly or an annual basis or
will sustain profitability if achieved. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
POTENTIAL FLUCTUATIONS IN RESULTS OF OPERATIONS
 
  The Company has experienced significant fluctuations in its results of
operations on a quarterly and an annual basis. The Company expects to continue
to experience significant fluctuations in its future quarterly and annual
results of operations due to a variety of factors, many of which are outside
the Company's control, including: demand for and market acceptance of the
Company's services and enhancements; introductions of services or enhancements
by the Company and its competitors; capacity utilization of its Internet Data
Centers; reliable continuity of service and network availability; the ability
to increase bandwidth as necessary; the timing of customer installations; the
mix of services sold by the Company; customer retention; the timing and
success of marketing efforts and service introductions by the Company; 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
 
                                       6
<PAGE>
 
networking technologies; increased competition in the Company's markets;
changes in the pricing policies of the Company and its competitors;
fluctuations in bandwidth used by customers; the retention of key personnel;
economic conditions specific to the Internet industry; and other general
economic factors. In addition, a relatively large portion of the Company's
expenses are fixed in the short-term, particularly with respect to
telecommunications, depreciation, real estate and interest expenses and
personnel, and therefore the Company's operating results are particularly
sensitive to fluctuations in revenues. Also, if the Company's agreement with
Computer Associates International, Inc. ("Computer Associates") were to
terminate and the Company continued to require Computer Associates' software,
the license fees paid by the Company could increase fixed costs significantly.
Furthermore, if the Company were to become unable to continue leveraging third
party products in the Company's services offerings, the Company's product
development costs could increase significantly. Although the Company has not
encountered significant difficulties in collecting upon accounts receivable in
the past, many of the Company's customers are in an emerging stage, and there
can be no assurance that the Company will be able to collect receivables on a
timely basis. For these and other reasons, in some future quarters, the
Company's results of operations may fall below the expectations of securities
analysts or investors, which could have a material adverse effect on the
market price of the Company's Common Stock. See "--Risks Associated with
Planned Expansion of the Exodus Network" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
RISKS ASSOCIATED WITH PLANNED BUSINESS EXPANSION
 
  A key element of the Company's business strategy is the expansion of the
Company's network through the opening of additional Internet Data Centers in
geographically diverse locations. The Company opened five Internet Data
Centers during 1997 and currently has six sites located in five metropolitan
areas: San Francisco, New York, Los Angeles, Seattle and Washington, D.C. The
Company intends to expand domestically and internationally, including the
expected addition of an additional Internet Data Center in the San Francisco
metropolitan area and a new site in the London metropolitan area in the first
half of 1998. The Company's continued expansion and development of its network
will depend on, among other things, the Company's ability to assess markets,
identify Internet Data Center sites, install facilities and establish local
peering interconnections with ISPs, all in a timely manner at reasonable costs
and on terms and conditions acceptable to the Company. The Company's ability
to manage this expansion effectively will require it to continue to implement
and improve its operational and financial systems and to expand, train and
manage its employee base. The Company's inability to establish additional
Internet Data Centers or manage effectively its expansion would have a
material adverse effect upon the Company's business, results of operations and
financial condition.
 
  The establishment of each additional Internet Data Center will require the
Company to expend substantial resources for leases of real estate, significant
improvements of such facilities, purchase of equipment, implementation of
multiple telecommunications connections and hiring of network, administrative,
customer support and sales and marketing personnel. Moreover, the Company
expects to make significant investments in sales and marketing and the
development of new services as part of its expansion strategy. During the next
12 months, the Company expects to meet its capital and working capital
requirements with existing cash and cash equivalents and short-term
investments, the proceeds of this offering, cash from sales of services and
proceeds from existing and future equipment loans and lease lines and working
capital lines of credit and possibly other borrowings. However, there can be
no assurance that the Company will be successful in generating sufficient cash
from sales of services or raising capital in sufficient amounts on terms
acceptable to it. The failure to generate sufficient cash flows from sales of
services or to raise sufficient funds may require the Company to delay or
abandon some or all of its development and expansion plans or otherwise forego
market opportunities and may make it difficult for the Company to respond to
competitive pressures, any of
 
                                       7
<PAGE>
 
which could have a material adverse effect on the Company's business, results
of operations and financial condition. See "Use of Proceeds" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."
 
  The Company typically requires 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, the Company expects
individual Internet Data Centers will experience losses for at least one year
from the time they are opened. The Company experiences further losses from
sales personnel hired to test market the Company's services in markets where
there is no, and may never be an, Internet Data Center. As a result, the
Company expects to make investments in expanding the Company's business
rapidly into new geographic regions which, while potentially increasing the
Company's revenues in the long term, will lead to significant losses for the
foreseeable future. There can be no assurance that the Company will be able to
anticipate accurately the customer demand for such additional Internet Data
Centers or that the Company will be able to attract a sufficient number of
customers to such facilities. The Company's inability to attract customers to
new Internet Data Centers in a timely manner, or at all, would have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
SUBSTANTIAL LEVERAGE AND DEBT SERVICE
 
  The Company is, and after the offering will continue to be, substantially
leveraged. On December 31, 1997, the Company's total long-term debt and
capital lease obligations was approximately $22.6 million and its borrowing
availability under existing equipment loans and working capital lines of
credit was approximately $15.8 million, subject to the borrowing conditions
contained therein. The Company also expects to obtain additional equipment
loans and lease lines and working capital lines of credit, and possibly other
borrowings, during the next 12 months. The degree to which the Company is
leveraged could have important consequences to the Company's future
operations, including but not limited to: (i) increasing the Company's
vulnerability to general adverse economic and industry conditions; (ii)
limiting the Company's ability to obtain additional financing to fund future
working capital, capital expenditures, acquisitions and other general
corporate requirements; (iii) requiring the dedication of a substantial
portion of the Company's cash flow from operations to the payment of principal
of, and interest on, its indebtedness, thereby reducing the availability of
such cash flow to fund working capital, capital expenditures or other general
corporate requirements; (iv) limiting the Company's flexibility in planning
for, or reacting to, changes in its business and the industry in which it
competes; and (v) placing the Company at a competitive disadvantage vis-a-vis
less leveraged or better capitalized competitors. Certain of the Company's
indebtedness is secured by the Company's assets. A default under such
indebtedness could result in the foreclosure on such collateral, which would
have a material adverse effect on the Company's business, results of
operations and financial condition.
 
  The Company's ability to fund planned capital expenditures and service its
existing and future indebtedness will depend upon its future performance,
which, in turn, is subject to general economic, financial, competitive,
legislative, regulatory and other factors that are beyond its control. If the
Company is unable to generate sufficient cash flow from operations, or
additional equipment loans or equipment and working capital lines of credit,
in the future to service its debt, it may be required to sell assets, reduce
capital expenditures, refinance all or a portion of its existing indebtedness
or obtain other sources of financing. There can be no assurance that any such
refinancing would be available on commercially reasonable terms, or at all, or
that any other financing could be obtained, particularly
 
                                       8
<PAGE>
 
in view of the Company's high level of indebtedness and the fact that
substantially all of the Company's assets have been pledged to secure
obligations under certain existing indebtedness. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and Notes 3 and
6 of Notes to Financial Statements.
 
COMPETITION
 
  The market served by the Company is highly competitive. There are few
substantial barriers to entry, and the Company expects that it 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 expertise, customer service, network capability,
reliability, quality of service and scalability, broad geographic presence,
brand name, technical expertise and functionality, the variety of services
offered, the ability to maintain and expand distribution channels, customer
support, price, the timing of introductions of new services, network security,
financial resources and conformity with industry standards. There can be no
assurance that the Company will have the resources or expertise to compete
successfully in the future.
 
  The Company's current and potential competitors in the market include: (i)
providers of server hosting services; (ii) national and regional Internet
service providers ("ISPs"); (iii) global, regional and local
telecommunications companies and Regional Bell Operating Companies ("RBOCs");
and (iv) large IT outsourcing firms. The Company's competitors may operate in
one or more of these areas and include companies such as certain subsidiaries
of GTE Corporation and WorldCom, Inc. ("WorldCom"), International Business
Machines Corporation ("IBM") and certain business units of GlobalCenter, Inc.
("GlobalCenter"), which recently announced its proposed acquisition by
Frontier Corporation.
 
  Many of the Company's competitors have substantially greater financial,
technical and marketing resources, larger customer bases, longer operating
histories, greater name recognition and more established relationships in the
industry than the Company. As a result, certain of these competitors may be
able to develop and expand their network infrastructures and service offerings
more quickly, adapt to new or emerging technologies and changes in customer
requirements more quickly, take advantage of acquisition and other
opportunities more readily, devote greater resources to the marketing and sale
of their products and adopt more aggressive pricing policies than can the
Company. In addition, these competitors have entered and will likely continue
to enter into joint ventures or consortiums to provide additional services
competitive with those provided by the Company.
 
  Certain of the Company's 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 the Company's. There
can be no assurance that the Company will be able to offset the effects of any
such price reductions. In addition, the Company believes that the businesses
in which the Company competes are likely to encounter consolidation in the
near future, which could result in increased price and other competition that
could have a material adverse effect on the Company's business, results of
operations and financial condition. See "Business--Competition."
 
DEPENDENCE ON NEW MARKET; UNCERTAINTY OF ACCEPTANCE OF SERVICES
 
  The market for Internet system and network management solutions has only
recently begun to develop, is evolving rapidly and likely will be
characterized by an increasing number of market entrants. There is significant
uncertainty regarding whether this market ultimately will prove to be viable
or, if it becomes viable, that it will grow. The Company's future growth, if
any, will be dependent on the willingness of enterprises to outsource the
system and network management of their mission-critical
 
                                       9
<PAGE>
 
Internet operations and the Company's ability to market its services in a
cost-effective manner to a sufficiently large number of customers. There can
be no assurance that the market for the Company's services will develop, that
the Company's services will be adopted or that businesses, organizations or
consumers will use the Internet for commerce and communication. If this market
fails to develop, or develops more slowly than expected, or if the Company's
services do not achieve market acceptance, the Company's business, results of
operations and financial condition would be materially and adversely affected.
In addition, in order to be successful in this emerging market, the Company
must be able to differentiate itself from its competition through its service
offerings, such as its recently introduced collaborative management and
Internet technology services. There can be no assurance that the Company will
be successful in differentiating itself or achieving market acceptance of its
services, or that it will not experience difficulties that could delay or
prevent the successful development, introduction or marketing of these
services. If the Company incurs increased costs or is unable, for technical or
other reasons, to develop and introduce new services or enhancements of
existing services in a timely manner, including certain collaborative
management and Internet technology services scheduled to be available in the
first half of 1998, or if these or other new products or services do not
achieve market acceptance in a timely manner or at all, the Company's
business, results of operations and financial condition could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
RISK OF SYSTEM FAILURE
 
  The Company's operations are dependent upon its ability to protect its
network infrastructure and customers' equipment against damage from human
error, fire, earthquakes, floods, power loss, telecommunications failures,
sabotage, intentional acts of vandalism and similar events. Despite
precautions taken by, and planned to be taken by the Company, the occurrence
of a natural disaster or other unanticipated problems at one or more of the
Company's Internet Data Centers could result in interruptions in the services
provided by the Company or significant damage to customer equipment. In
addition, failure of any of the Company's telecommunications providers, such
as WorldCom, to provide the data communications capacity required by the
Company, as a result of human error, a natural disaster or other operational
disruption, could result in interruptions in the Company's services. Any
damage to or failure of the systems of the Company or its service providers
could result in reductions in, or terminations of, services supplied to the
Company's customers, which could have a material adverse effect on the
Company's business, results of operations and financial condition. In
addition, the Company's reputation could be materially adversely affected.
 
  Certain of the Company's customer contracts currently provide a limited
service level warranty related to the continuous availability of service on a
24 hours per day, seven days per week ("24x7") basis, except for certain
scheduled maintenance periods. This warranty is generally limited to a credit
consisting of free service for a specified limited period of time for
disruptions in Internet transmission services. Should the Company incur
significant obligations in connection with system downtime, there can be no
assurance that the Company's liability insurance would be adequate to cover
such expenses. The Company's customer contracts provide for liability of the
Company for personal injury or equipment damage in only limited circumstances.
Although these customer contracts typically provide for no recovery with
respect to incidental, punitive, indirect and consequential damages resulting
from damages to equipment or disruption of service, there can be no assurance
that, in the event of such damages, the Company would not be found liable,
and, in such event, that such damages would not exceed the Company's liability
insurance. See "Business--Customers" and "--Network Design."
 
UNPROVEN NETWORK SCALABILITY
 
  The Company must continue to expand and adapt its network infrastructure as
the number of users and the amount of information they wish to transport
increase and to meet changing customer
 
                                      10
<PAGE>
 
requirements. The expansion and adaptation of the Company's telecommunications
infrastructure will require substantial financial, operational and management
resources as the Company negotiates telecommunications capacity with its
existing and other network infrastructure suppliers. If the Company is
required to expand significantly and rapidly its network due to increased
usage, additional stress will be placed upon the Company's network hardware
and traffic management systems. Due to the limited deployment of the Company's
services to date, the ability of the Company's network to connect and manage a
substantially larger number of customers at high transmission speeds is as yet
unknown, and the Company faces risks related to the network's ability to be
scaled up to its expected customer levels while maintaining superior
performance. As customers' usage of bandwidth increases, the Company will need
to make additional investments in its infrastructure to maintain adequate
downstream data transmission speeds, the availability of which may be limited
or the cost of which may be significant. There can be no assurance that
additional network capacity will be available from third-party suppliers as it
is needed by the Company. As a result, there can be no assurance that the
Company's network will be able to achieve or maintain a sufficiently high
capacity of data transmission, especially if the usage of the Company's
customers increases. The Company's failure to achieve or maintain high
capacity data transmission could significantly reduce consumer demand for its
services and have a material adverse effect on its business, results of
operations and financial condition. In addition, as the Company upgrades its
telecommunications infrastructure to increase bandwidth available to its
customers, it is likely to encounter a certain level of equipment or software
incompatibility which may cause delays in implementation. There can be no
assurance that the Company will be able to expand or adapt its
telecommunications infrastructure to meet additional demand or its customers'
changing requirements, including its planned upgrade to an OC-3c backbone
within the first half of 1998, on a timely basis and at a commercially
reasonable cost, or at all. See "Business--Network Design."
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE
 
  The Company's success will depend upon the capacity, scalability,
reliability and security of its network infrastructure, including the capacity
leased from its telecommunications network suppliers. In particular, the
Company is dependent on WorldCom and certain other telecommunications
providers for its backbone capacity and is therefore dependent on such
companies to maintain the operational integrity of its backbone. In addition,
the Company relies on a number of public peering interconnections and private
peering interconnections to deliver its services. If the carriers that operate
the Internet exchange points ("IXPs") were to discontinue their support of the
peering points and no alternative providers emerged, or such alternative
providers increased the cost of utilizing the IXPs, the distribution of
content through the IXPs, including content distributed by the Company, would
be significantly constrained. Furthermore, as traffic through the IXPs
increases, if commensurate increases in bandwidth are not added, the Company's
ability to distribute content rapidly and reliably through these networks will
be adversely affected. Many of the operators of the private peering
interconnections are competitors of the Company. Currently, the Company does
not pay a fee for many of these interconnections, and if these organizations
were to begin to charge the Company for utilizing these interconnections, or,
in the cases where the Company currently pays a fee, to increase the pricing
associated with utilizing these networks, the Company may be required to
identify alternative methods through which it can distribute its customers'
content. If the Company were unable to access on a cost-effective basis
alternative networks to distribute its customers' content or pass through any
additional costs of utilizing these networks to its customers, the Company's
business, results of operations and financial condition could be materially
adversely affected. See "Business--Network Design."
 
DEPENDENCE ON THE INTERNET AND INTERNET INFRASTRUCTURE DEVELOPMENT
 
  The increased use of the Internet for retrieving, sharing and transferring
information among businesses, consumers, suppliers and partners has only
recently begun to develop, and the
 
                                      11
<PAGE>
 
Company's 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 the Company's services. The
adoption of the Internet for information retrieval and exchange, commerce and
communications, particularly by those enterprises that have historically
relied upon alternative means of commerce and communications, generally will
require the acceptance of a new medium of conducting business and exchanging
information. Demand and market acceptance of the Internet are subject to a
high level of uncertainty and are dependent on a number of factors, including
the growth in consumer access to and acceptance of new interactive
technologies, the development of technologies that facilitate interactive
communication between organizations and targeted audiences and increases in
user bandwidth. If the Internet as a commercial or business medium fails to
develop or develops more slowly than expected, the Company's business, results
of operations and financial condition could be materially adversely affected.
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 the Company's services. Potentially increased
performance provided by the services of the Company and others is ultimately
limited by and reliant upon the speed and reliability of networks operated by
third parties. Consequently, the emergence and growth of the market for the
Company's services is dependent on improvements being made to the entire
Internet infrastructure to alleviate overloading and congestion. See
"Business--Network Design."
 
RAPID TECHNOLOGICAL CHANGE; EVOLVING INDUSTRY STANDARDS
 
  The Company's future success will depend, in part, on its ability to offer
services that incorporate leading technology, address the increasingly
sophisticated and varied needs of its current and prospective customers and
respond to technological advances and emerging industry standards and
practices on a timely and cost-effective basis. The market for the Company's
services is characterized by rapidly changing and unproven technology,
evolving industry standards, changes in customer needs, emerging competition
and frequent new service introductions. There can be no assurance that future
advances in technology will be beneficial to, or compatible with, the
Company's business or that the Company will be able to incorporate such
advances on a cost-effective and timely basis into its business. Moreover,
technological advances may have the effect of encouraging certain of the
Company's current or future customers to rely on in-house personnel and
equipment to furnish the services currently provided by the Company. In
addition, keeping pace with technological advances in the Company's industry
may require substantial expenditures and lead time. For instance, certain
networking hardware may not be immediately compatible with leading edge
telecommunications infrastructure services, such as WorldCom's OC-3c service,
which is not yet widely available and therefore may require the Company to
make significant investments to achieve compatibility.
 
  The Company believes that its ability to compete successfully is also
dependent upon the continued compatibility and interoperability of its
services with products, services and architectures offered by various vendors.
Although the Company often works with various vendors in testing newly
developed products, there can be no assurance that such products will be
compatible with the Company's infrastructure or that such products will
adequately address changing customer needs. Although the Company currently
intends to support emerging standards, there can be no assurance that industry
standards will be established or, that if they become established, the Company
will be able to conform to these new standards in a timely fashion and
maintain a competitive position in the market. The failure of the Company to
conform to the prevailing standard, or the failure of a common standard to
emerge, could have a material adverse effect on the Company's business,
results of operations and financial condition. In addition, there can be no
assurance that products, services or
 
                                      12
<PAGE>
 
technologies developed by others will not render the Company's services
uncompetitive or obsolete. See "Business--Product Development."
 
SYSTEM SECURITY RISKS
 
  A significant barrier to electronic commerce and communications is the
secure transmission of confidential information over public networks. Certain
of the Company's services rely on encryption and authentication technology
licensed from third parties to provide the security and authentication
necessary to effect secure transmission of confidential information. Despite
the Company's design and implementation of a variety of network security
measures, there can be no assurance that unauthorized access, computer
viruses, accidental or intentional actions and other disruptions will not
occur. The Company's Internet Data Centers have in the past 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 potentially jeopardize the security of confidential
information, such as credit card and bank account numbers, stored in the
computer systems of the Company and its customers, which could result in
liability to the Company and the loss of existing customers or the deterrence
of potential customers. Although the Company intends to continue to implement
industry-standard security measures, such measures have been circumvented in
the past, and there can be no assurance that any such measures implemented by
the Company will not be circumvented in the future. 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 the Company's customers,
which could have a material adverse effect on the Company's business, results
of operations and financial condition. Concerns over the security of Internet
transactions and the privacy of users may also inhibit the growth of the
Internet, especially as a means of conducting commercial transactions. See
"Business--Network Design."
 
DEPENDENCE ON THIRD-PARTY SUPPLIERS
 
  The Company is dependent on other companies to supply certain key components
of its telecommunications infrastructure and system and network management
solutions, including telecommunications services and networking equipment
that, in the quantities and quality demanded by the Company, are available
only from sole or limited sources. See "--Dependence Upon Network
Infrastructure." The routers, switches and modems used in the Company's
telecommunications infrastructure are currently supplied primarily by Cisco
Systems Inc. ("Cisco"). The Company purchases these components pursuant to
purchase orders placed from time to time, does not carry significant
inventories of these components and has no guaranteed supply arrangements with
these vendors. Any failure to obtain required products or services on a timely
basis and at an acceptable cost would have a material adverse effect on the
Company's business, results of operations and financial condition. In
addition, any failure of the Company's 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 used by the Company in its communications infrastructure could have
a material adverse effect on the Company's business, results of operations and
financial condition. In addition, the Company expects to be dependent for a
time on third parties to deliver its services from and manage the operations
of its international Internet Data Centers. See "--Risks Associated with
International Operations" and "Business--Network Design."
 
  The Company has also licensed certain software from Computer Associates
which allows the Company to monitor its customers' Internet operations and
assist in resolving performance issues that arise from time to time. Under the
agreement with Computer Associates, to the extent that Computer Associates
offers software that includes functionality that the Company wants to provide
in its service offerings, the Company must generally utilize the software
offered by Computer Associates, as long as such software meets the Company's
requirements. Either party may terminate this agreement upon
 
                                      13
<PAGE>
 
60 days' prior written notice. Should Computer Associates or the Company decide
to terminate this agreement, the Company has the right to continue licensing
software from Computer Associates at a discount for five years. During the term
of the agreement, the Company is obligated to pay Computer Associates a royalty
based on the Company's gross revenues. See "Business--Relationship with
Computer Associates."
 
MANAGEMENT OF GROWTH
 
  The Company is currently experiencing a period of rapid growth with respect
to the building of its Internet Data Centers and expansion of its customer
base. In addition, from December 31, 1996 to December 31, 1997, the number of
Company employees increased from 55 to 220. This growth has placed, and if it
continues, will place, a significant strain on the Company's financial,
management, operational and other resources. In addition, the Company may be
required to manage multiple relationships with a growing number of third
parties as it seeks to complement its service offerings. There can be no
assurance that the Company's management, personnel, systems, procedures and
controls will be adequate to support the Company's existing and future
operations. The Company's ability to manage its growth effectively will require
it to continue to expand its operating and financial procedures and controls,
to replace or upgrade its operational, financial and management information
systems and to attract, train, motivate, manage and retain key employees. The
Company has recently hired many key employees and officers, and as a result,
the Company's entire management team has worked together for only a brief time.
The Company also has plans to hire additional executive management personnel in
the near future. If the Company's executives are unable to manage growth
effectively, the Company's business, results of operations and financial
condition could be materially adversely affected. See "Management."
 
GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES
 
  The Company is not currently subject to direct federal, state or local
government regulation, other than regulations applicable to businesses
generally. There is currently only a small body of laws and regulations
directly applicable to access to or commerce on the Internet. However, due to
the increasing popularity and use of the Internet, it is possible that a number
of laws and regulations may be adopted at the federal, state and local levels
with respect to the Internet, covering issues such as user privacy, freedom of
expression, pricing, characteristics and quality of products and services,
taxation, advertising, intellectual property rights, information security and
the convergence of traditional telecommunications services with Internet
communications. Although sections of the Communications Decency Act of 1996
(the "CDA") that, among other things, proposed to impose criminal penalties on
anyone distributing "indecent" material to minors over the Internet, were held
to be unconstitutional by the U.S. Supreme Court, there can be no assurance
that similar laws will not be proposed and adopted. The nature of such similar
legislation and the manner in which it may be interpreted and enforced cannot
be fully determined and, therefore, legislation similar to the CDA could
subject the Company and/or its customers to potential liability, which in turn
could have an adverse effect on the Company's business, results of operations
and financial condition. The adoption of any such laws or regulations might
decrease the growth of the Internet, which in turn could decrease the demand
for the services of the Company or increase the cost of doing business or in
some other manner have a material adverse effect on the Company's business,
results of operations or financial condition. In addition, applicability to the
Internet of existing laws governing issues such as property ownership,
copyrights and other intellectual property issues, taxation, libel, obscenity
and personal privacy is uncertain. The vast majority of such laws were adopted
prior to the advent of the Internet and related technologies and, as a result,
do not contemplate or address the unique issues of the Internet and related
technologies. Changes to such laws intended to address these issues, including
some recently proposed changes, could create uncertainty in the marketplace
which could reduce demand for the services of the Company or increase the cost
of doing business as a result of costs of litigation or increased service
delivery costs, or could in some other manner have a material adverse effect on
the
 
                                       14
<PAGE>
 
Company's business, results of operations and financial condition. In
addition, as the Company's services are available over the Internet in
multiple states and foreign countries, and as the Company facilitates sales by
its customers to end users located in such states and foreign countries, such
jurisdictions may claim that the Company is required to qualify to do business
as a foreign corporation in each such state or foreign country. The Company is
qualified to do business in only a limited number of states, and failure by
the Company to qualify as a foreign corporation in a jurisdiction where it is
required to do so could subject the Company to taxes and penalties for the
failure to qualify and could result in the inability of the Company to enforce
contracts in such jurisdictions. Any such new legislation or regulation, or
the application of laws or regulations from jurisdictions whose laws do not
currently apply to the Company's business, could have a material adverse
effect on the Company's business, results of operations and financial
condition. See "Business--Government Regulation."
 
RISKS ASSOCIATED WITH INFORMATION DISSEMINATED THROUGH THE COMPANY'S 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. It is possible that claims could be made
against online services companies and Internet access providers under both
United States and foreign law for defamation, negligence, copyright or
trademark infringement, or other theories based on the nature and content of
the materials disseminated through their networks. Several private lawsuits
seeking to impose such liability upon online services companies and Internet
access providers are currently pending. In addition, legislation has been
proposed that imposes liability for or prohibits the transmission over the
Internet of certain types of information. The imposition upon the Company and
other Internet network providers of potential liability for information
carried on or disseminated through their systems could require the Company to
implement measures to reduce its exposure to such liability, which may require
the expenditure of substantial resources, or to discontinue certain service or
product offerings. The increased attention focused upon liability issues as a
result of these lawsuits and legislative proposals could impact the growth of
Internet use. While the Company carries professional liability insurance, it
may not be adequate to compensate or may not cover the Company in the event
the Company becomes liable for information carried on or disseminated through
its networks. Any costs not covered by insurance incurred as a result of such
liability or asserted liability could have a material adverse effect on the
Company's business, results of operations and financial condition. Certain
businesses, organizations and individuals have in the past sent unsolicited
commercial e-mails from servers hosted at the Company's facilities to massive
numbers of people, typically to advertise products or services. This practice,
known as "spamming," can lead to complaints against service providers that
enable such activities, particularly where recipients view the materials
received as offensive. In addition, certain ISPs and other online services
companies could deny network access to companies that allow undesired content
or spamming to be transmitted through their networks. The Company has in the
past received, and may in the future receive, letters from recipients of
information transmitted by the Company's customers objecting to such
transmission. Although the Company prohibits its customers by contract from
spamming, there can be no assurance that its customers will not engage in this
practice, which could have a material adverse effect on the Company's
business, results of operations and financial condition. See "Business--
Government Regulation."
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  A component of the Company's long-term strategy is to expand into
international markets, and the Company currently plans to open an Internet
Data Center in the London metropolitan area in the first half of 1998. If
revenue generated by any current or future international Internet Data Center
is not adequate to offset the expense of establishing and maintaining any such
international operation, the Company's business, results of operations and
financial condition could be materially adversely affected. There can be no
assurance that the Company will be able to market, sell and deliver
successfully its services outside the United States. The Company generally
intends to outsource the
 
                                      15
<PAGE>
 
initial operation of its international Internet Data Centers. As a result, the
Company will be dependent for a time on third parties to deliver its services
from and manage the operations of such international Internet Data Centers. In
addition to the uncertainty as to the Company's ability to expand into
international markets, there are certain risks inherent in conducting business
internationally, such as unexpected changes in regulatory requirements, export
restrictions, tariffs and other trade barriers, challenges in staffing and
managing foreign operations, differing technology standards, employment laws
and practices in foreign countries, longer payment cycles, problems in
collecting accounts receivable, political instability, fluctuations in
currency exchange rates, imposition of currency exchange controls, seasonal
reductions in business activity and potentially adverse tax consequences, any
of which could adversely affect the Company's international operations.
Furthermore, certain foreign governments, such as Germany, have enforced laws
and regulations related to content distributed over the Internet that are more
strict than those currently in place in the United States. There can be no
assurance that one or more of these factors will not have a material adverse
effect on the Company's current or future international operations and,
consequently, on the Company's business, results of operations and financial
condition. In addition, there can be no assurance that the Company will be
able to obtain the necessary telecommunications infrastructure in a cost-
effective manner or compete effectively in international markets. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company's success depends in significant part upon the continued
services of its key technical, sales and senior management personnel,
including the Company's President, Chief Executive Officer and Chairman of the
Board of Directors, K.B. Chandrasekhar. Although certain of the Company's
executive officers participate in the Company's Executive Employment Policy,
none of the Company's officers is a party to an employment agreement with the
Company. Any officer or employee of the Company can terminate his or her
relationship with the Company at any time. The Company's future success will
also depend on its ability to attract, train, retain and motivate highly
qualified technical, marketing, sales and management personnel. Competition
for such personnel is intense, and there can be no assurance that the Company
will be able to attract and retain key personnel. The loss of the services of
one or more of the Company's key employees or the Company's failure to attract
additional qualified personnel could have a material adverse effect on the
Company's business, results of operations and financial condition. The Company
does not carry key-man life insurance for any of its employees. See
"Business--Employees" and "Management."
 
RISKS ASSOCIATED WITH LEGAL PROCEEDINGS
 
  On July 30, 1997, Michael Blackman ("Blackman"), a consultant to the Company
from October 1996 through January 1997, filed a complaint against the Company
in the Superior Court for the State of California in and for the County of
Santa Clara alleging damages suffered as a result of the Company's failure to
grant Blackman stock options for the Company's Common Stock as additional
compensation for consulting work he performed for the Company pursuant to an
alleged oral contract between Blackman and another consultant to the Company.
The Company believes that the suit is without merit and intends to contest the
suit vigorously. However, litigation is subject to inherent uncertainties,
and, therefore, there can be no assurance that this lawsuit will be resolved
in the Company's favor. See "Business--Legal Proceedings."
 
PROTECTION AND ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS
 
  The Company relies on a combination of copyright, trademark, service mark
and trade secret laws and contractual restrictions to establish and protect
certain proprietary rights in its products and services. The Company has no
patented technology that would preclude or inhibit competitors from entering
the Company's market. The Company has entered into confidentiality and
invention
 
                                      16
<PAGE>
 
assignment agreements with its employees and contractors, and nondisclosure
agreements with its suppliers, distributors and appropriate customers in order
to limit access to and disclosure of its proprietary information. There can be
no assurance that these contractual arrangements or the other steps taken by
the Company to protect its intellectual property will prove sufficient to
prevent misappropriation of the Company's technology or to deter independent
third-party development of similar technologies. The laws of certain foreign
countries may not protect the Company's products, services or intellectual
property rights to the same extent as do the laws of the United States. The
Company also relies on certain technologies that it licenses from third
parties, such as Computer Associates. See "--Dependence on Third-Party
Suppliers." There can be no assurance that these third-party technology
licenses will continue to be available to the Company on commercially
reasonable terms. The loss of such technology could require the Company to
obtain substitute technology of lower quality or performance standards or at
greater cost, which could materially adversely affect the Company's business,
results of operations and financial condition.
 
  To date, the Company has not been notified that the Company's products
infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. The Company expects that participants
in its markets will be increasingly subject to infringement claims as the
number of products and competitors in the Company's industry segment grows.
Any such claim, whether meritorious or not, could be time- consuming, result
in costly litigation, cause product installation delays or require the Company
to enter into royalty or licensing agreements. Such royalty or licensing
agreements might not be available on terms acceptable to the Company or at
all. As a result, any such claim could have a material adverse effect upon the
Company's business, results of operations and financial condition. See
"Business--Intellectual Property Rights."
 
YEAR 2000 RISKS
 
  The Company recognizes the need to ensure its operations will not be
adversely impacted by Year 2000 software failures. Software failures due to
processing errors potentially arising from calculations using the year 2000
date are a known risk. The Company has established procedures for evaluating
and managing the risks and costs associated with this problem and estimates
that expenses required to improve computer systems to be Year 2000 compliant
will not be material. However, many of the Company's customers maintain their
Internet operations on UNIX-based servers, which may be impacted by Year 2000
complications. The failure of such servers could have a material adverse
effect on the Company's customers, which in turn could have a material adverse
effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  The market price of the shares of Common Stock is likely to be highly
volatile and could be subject to wide fluctuations in response to factors such
as actual or anticipated variations in the Company's results of operations,
announcements of technological innovations or new Internet Data Centers, new
products or services introduced by the Company or its competitors, changes in
financial estimates by securities analysts, conditions and trends in the
Internet, general market conditions and other factors. Further, the stock
markets, and in particular the Nasdaq National Market, have experienced
extreme price and volume fluctuations that have particularly affected the
market prices of equity securities of many technology companies and that often
have been unrelated or disproportionate to the operating performance of such
companies. The trading prices of many technology companies' stocks are at or
near historical highs and reflect price to earnings ratios substantially above
historical levels. There can be no assurance that these trading prices and
price to earnings ratios will be sustained. These broad market factors may
adversely affect the market price of the Company's Common Stock. These market
fluctuations, as well as general economic, political and market conditions
such as recessions, interest
 
                                      17
<PAGE>
 
rates or international currency fluctuations, may adversely affect the market
price of the Common Stock. In the past, following periods of volatility in the
market price of a company's securities, securities class action litigation has
often been instituted against such companies. Such litigation, if instituted,
could result in substantial costs and a diversion of management's attention
and resources, which would have a material adverse effect on the Company's
business, results of operations and financial condition.
 
CONTROL BY PRINCIPAL STOCKHOLDERS, EXECUTIVE OFFICERS AND DIRECTORS
 
  Upon completion of this offering, the Company's executive officers,
directors and existing greater than 5% stockholders (and their affiliates)
will, in the aggregate, own approximately    % of the Company's outstanding
Common Stock (   % if the Underwriters' over-allotment option is exercised in
full). As a result, such persons, acting together, will have the ability to
control all matters submitted to stockholders of the Company for approval
(including the election and removal of directors and any merger, consolidation
or sale of all or substantially all of the Company's assets) and to control
the management and affairs of the Company. Accordingly, such concentration of
ownership may have the effect of delaying, deferring or preventing a change in
control of the Company, impede a merger, consolidation, takeover or other
business combination involving the Company or discourage a potential acquirer
from making a tender offer or otherwise attempting to obtain control of the
Company, which in turn could have an adverse effect on the market price of the
Company's Common Stock. See "Management" and "Principal and Selling
Stockholders."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial amounts of the Company's Common Stock (including shares
issued upon the exercise of outstanding options and warrants) in the public
market after this offering could adversely affect the market price of the
Common Stock. Such sales also might make it more difficult for the Company to
sell equity or equity-related securities in the future at a time and price
that the Company deems appropriate. In addition to the     shares of Common
Stock offered hereby (assuming no exercise of the Underwriters' over-allotment
option), as of the date of this Prospectus, there will be 13,439,624 shares of
Common Stock outstanding, all of which are restricted shares ("Restricted
Shares") under the Securities Act of 1933, as amended (the "Securities Act").
As of such date, no Restricted Shares will be eligible for sale in the public
market. Following the expiration of 180-day lock-up agreements with the
representatives of the Underwriters, 12,086,491 Restricted Shares will be
available for sale in the public market and the remaining Restricted Shares
will be eligible for sale from time to time thereafter upon expiration of
applicable holding periods under Rule 144 under the Securities Act. In
addition, as of December 31, 1997, there were outstanding 1,709,286 options
and 950,163 warrants to purchase Common Stock (of which warrants for 615,454
shares are expected to be exercised on or before the closing of this offering)
and all of such options and warrants will be subject to lock-up agreements.
Goldman, Sachs & Co. may, in its sole discretion and at any time without
notice, release all or any portion of the securities subject to lock-up
agreements. In addition, the holders of 13,234,880 Restricted Shares and
warrants to purchase 950,163 shares of Common Stock of the Company are
entitled to certain rights with respect to registration of such shares for
sale in the public market. If such holders sell in the public market, such
sales could have a material adverse effect on the market price of the
Company's Common Stock.
 
  Immediately after this offering, the Company intends to register
approximately 4,659,215 shares of Common Stock reserved for issuance under its
stock option and purchase plans. See "Shares Eligible for Future Sale."

BROAD MANAGEMENT DISCRETION IN ALLOCATION OF PROCEEDS
 
  The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby at an assumed initial public offering price of $    per share,
after deducting the estimated underwriting discount and offering expenses, are
estimated to be approximately $   . The primary purposes of this offering are
to obtain additional capital, create a public market for the Common Stock and
facilitate future access to public markets. The Company expects to use the net
proceeds primarily for working capital and other general corporate purposes,
including scheduled payments of principal and interest on outstanding
indebtedness. A portion of the net proceeds also may be used to repay
currently outstanding or future indebtedness, to acquire or invest in
complementary businesses or products or to obtain the right to use
complementary technologies. Accordingly, the Company's management will retain
broad discretion as to the allocation of most of the proceeds of this
offering. The failure of management to apply such funds effectively could have
a material adverse effect on the Company's business, results of operations and
financial condition. See "Use of Proceeds."
 
ANTI-TAKEOVER EFFECTS OF DELAWARE LAW
 
  Upon completion of this offering, the Company's Board of Directors will have
the authority to issue up to 5,000,000 shares of Preferred Stock and to
determine the price, rights, preferences, privileges and restrictions,
including voting rights, of those shares without any further vote or action by
the stockholders. The rights of the holders of Common Stock will be subject
to, and may be adversely affected by, the rights of the holders of any
Preferred Stock that may be issued in the future. The issuance of Preferred
Stock, while providing flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of making it more
difficult for a third party to acquire a majority of the outstanding voting
stock of the Company. The Company has no current plans to issue shares of
Preferred Stock. The Company is also subject to certain provisions of Delaware
law which could have the effect of delaying, deterring or preventing a change
in control of the Company, including Section 203 of the Delaware General
Corporation Law, which prohibits a Delaware corporation from engaging in any
business combination with any interested stockholder for a period of three
years from the date the person became an interested stockholder unless certain
conditions are met. In addition, the Company's certificate of incorporation
and bylaws contain certain provisions that, together with the ownership
position of the Company's executive officers and directors and their
affiliates, could discourage potential takeover attempts and make more
difficult attempts by stockholders to change management which could adversely
affect the market price of the Company's Common Stock. See "Description of
Capital Stock."
 
NO PRIOR MARKET FOR COMMON STOCK
 
  Prior to this offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market will
develop or be sustained after this offering or that investors will be able to
sell the Common Stock should they desire to do so. The initial public offering
price will be determined by negotiations between the Company and the
representatives of the Underwriters and may bear no relationship to the price
at which the Common Stock will trade upon completion of this offering. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price.
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
  Purchasers of the Common Stock in this offering will suffer immediate and

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the     shares of Common
Stock offered hereby are estimated to be $    million at an assumed initial
public offering price of $    per share and after deducting the estimated
underwriting discount and offering expenses ($    million if the over-
allotment option is exercised in full). The primary purposes of this offering
are to obtain additional capital, create a public market for the Common Stock
and facilitate future access to public markets. The Company expects to use the
net proceeds primarily for working capital and other general corporate
purposes, including scheduled payments of principal and interest on
outstanding indebtedness. See "Risk Factors--Broad Management Discretion in
Allocation of Proceeds." A portion of the proceeds may also be used to repay
currently outstanding or future indebtedness, to acquire or invest in
complementary businesses or products or to obtain the right to use
complementary technologies. In the ordinary course of business, the Company
evaluates potential acquisitions of such businesses, products or technologies.
However, the Company has no present understandings, commitments or agreements
with respect to any acquisition of businesses, products or technologies.
Pending use of the net proceeds for the above purposes, the Company intends to
invest such funds in short-term, interest-bearing, investment-grade
securities.
 
                                DIVIDEND POLICY
 
  The Company has not paid any cash dividends on its capital stock to date.
The Company currently anticipates that it will retain any future earnings for
use in its business and does not anticipate paying any cash dividends for the
foreseeable future.

                                   DILUTION
 
  The pro forma net tangible book value of the Company as of September 30,
1997 was $17.5 million, or $1.32 per share of Common Stock, assuming (i) the
sale by the Company of 877,180 shares of Preferred Stock at $8.55 per share in
December 1997 and (ii) the conversion of all outstanding shares of Preferred
Stock into shares of Common Stock. "Pro forma net tangible book value per
share" is determined by dividing the number of outstanding shares of Common
Stock into the net tangible book value of the Company (total tangible assets
less total liabilities). After giving effect to the application of the
estimated net proceeds from the sale by the Company of the     shares of
Common Stock offered hereby (based upon an assumed initial public offering
price of $    per share and after deducting the estimated underwriting
discount and offering expenses), the pro forma net tangible book value of the
Company as of September 30, 1997 would have been approximately $    million,
or $    per share. This represents an immediate increase in pro forma net
tangible book value of $    per share to existing stockholders and an
immediate dilution of $    per share to new investors purchasing shares at the
initial public offering price. The following table illustrates the per share
dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Financial
Statements and Notes thereto included elsewhere in this Prospectus. This
discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ materially from those
anticipated in these forward-looking statements. Factors that may cause such a
difference include, but are not limited to, those set forth under "Risk
Factors."
 
OVERVIEW
 
  Exodus is a leading provider of Internet system and network management
solutions for enterprises with mission-critical Internet operations. The
Company's solutions include server hosting, Internet connectivity,
collaborative management and Internet technology services, which together
provide the high performance, scalability and expertise that enterprises need
to optimize Internet operations. The Company delivers its services from
geographically distributed, state-of-the-art Internet Data Centers that are
connected through a redundant high performance Internet backbone ring.
 
  The Company is the successor to a Maryland Corporation that was formed in
August 1992 to provide computer consulting services. The Company began to
offer Internet connectivity services to enterprises in October 1994 and server
hosting services in late 1995. In August 1996, the Company opened its first
dedicated Internet Data Center and refocused its business strategy on
providing Internet system and network management solutions for enterprises
with mission-critical Internet operations. Since refocusing its business
strategy, the Company has derived most of its revenues (and substantially all
of its growth in revenues) from customers for which it provides these
services. Each of the Company's Internet Data Center customers initially
purchases a subset of the Company's service offerings to address specific
departmental or enterprise Internet computing needs, and some of these
customers purchase additional services as the scale and complexity of their
Internet operations increase. The Company sells its 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 any
equipment that they choose to purchase from the Company.
 
  The Company opened its first Internet Data Center in the San Francisco
metropolitan area in August 1996. Since that time, the Company has opened five
additional Internet Data Centers in the metropolitan areas of New York (March
1997), San Francisco (second site--August 1997), Seattle (September 1997), Los
Angeles (October 1997) and Washington, D.C. (December 1997). See "Business--
Facilities." These state-of-the-art facilities serve as a base for the array
of solutions offered by the Company, including server hosting, Internet
connectivity, collaborative management and Internet technology services. The
building of these Internet Data Centers has required the Company to obtain
substantial additional equity and debt financing. See "Risk Factors--
Substantial Leverage and Debt Service" and "--Liquidity and Capital Resources"
below.
 
  The Company intends to expand domestically and internationally, including
the expected addition of an additional Internet Data Center in the San
Francisco metropolitan area and a new site in the London metropolitan area in
the first half of 1998. Prior to building an Internet Data Center in a new a
geographic region, the Company employs various means to evaluate the market
opportunity in a given location, including the use of focus groups and market
research on Internet usage statistics, the pre-selling of services into the
proposed market and analysis of specific financial criteria. The Company
typically requires 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
 
                                      25
<PAGE>
 
period to approach break-even capacity utilization at each site. As a result,
the Company expects that individual Internet Data Centers will experience
losses for at least one year from the time they are opened. The Company
experiences further losses from sales personnel hired to test market the
Company's services in markets where there is no, and may never be an, Internet
Data Center. As a result, the Company expects to make investments in expanding
the Company's business rapidly into new geographic regions which, while
potentially increasing the Company's revenues in the long term, will lead to
significant losses for the foreseeable future. The Company also contemplates
that such expansion will lead to substantial needs for further financing. See
"Risk Factors--Risks Associated with Planned Business Expansion."
 
  Since the Company began to offer server hosting services in 1995, it has
experienced operating losses and negative cash flows from operations in each
quarterly and annual period. As of September 30, 1997, the Company had an
accumulated deficit of approximately $20.7 million. The revenue and income
potential of the Company's business and market is unproven, and the Company's
limited operating history makes an evaluation of the Company and its prospects
difficult. Currently, the Company anticipates making significant investments in
new Internet Data Centers, product development and sales and marketing programs
and personnel and therefore believes that it will continue to experience net
losses on a quarterly and annual basis for the foreseeable future. The Company
and its prospects must be considered in light of the risks, expenses and
difficulties encountered by companies in the new and rapidly evolving market
for Internet system and network management solutions. To address these risks,
among other things, the Company must market its brand name effectively, provide
scalable, reliable and cost-effective services, continue to grow its
infrastructure to accommodate new Internet Data Centers and increased bandwidth
use of its networks, expand its channels of distribution, retain and motivate
qualified personnel and continue to respond to competitive developments.
Failure of the Company's services to achieve market acceptance would have a
material adverse effect on the Company's business, results of operations and
financial condition. There can be no assurance that the Company will ever
achieve profitability on a quarterly or an annual basis or will sustain
profitability if achieved. See "Risk Factors--Limited Operating History;
History of Losses."

QUARTERLY RESULTS OF OPERATIONS
 
  The following table sets forth certain consolidated statement of operations
data as a percentage of total revenues for the quarters ended December 31,
1996 and March 31, June 30 and September 30, 1997. This information has been
derived from the Company's unaudited financial statements, which, in
management's opinion, have been prepared on substantially the same basis as
the audited financial statements and include all adjustments, consisting only
of normal recurring adjustments, necessary for a fair presentation of the
financial information for the quarters presented. This information should be
read in conjunction with the Financial Statements and Notes thereto included
elsewhere in this Prospectus. The operating results in any quarter are not
necessarily indicative of the results for any future period.

 REVENUES
 
  Service revenues consist of monthly fees for server hosting, Internet
connectivity, collaborative management and Internet technology services and
one-time fees for installation. Service revenues (other than installation
fees) are generally billed and recognized ratably over the term of the
contract, generally one year. Installation fees are typically recognized at
the time that installation occurs. Equipment revenues consist of payments from
customers for third-party equipment sold by the Company. Revenues from
equipment sales are recognized at the time the equipment is shipped to the
customer or placed into service at an Internet Data Center.
 
  The Company's revenues increased sequentially each quarter from $1.1 million
to $1.7 million to $2.4 million and to $3.4 million in the quarters ended
December 31, 1996 and March 31, June 30 and September 30, 1997, respectively.
The Company's service revenues also increased sequentially each quarter from
$954,000 to $1.6 million to $2.2 million and to $3.3 million in the quarters
ended December 31, 1996 and March 31, June 30 and September 30, 1997,
respectively. This growth in service revenues resulted primarily from
increases in the number of customers, increases in revenues from existing
customers and the opening of new Internet Data Centers. The Company's service
revenues increased as a percentage of total revenues in 1997 as the Company
increased its average service revenues per customer. The Company anticipates
that service revenues as a percentage of total revenues, although varying from
quarter to quarter, will generally continue to increase in 1998. The Company
sells third-party equipment to its customers as an accommodation to facilitate
their
 
                                      27
<PAGE>
 
purchase of services; thus, the Company's equipment revenues have varied from
quarter to quarter depending on particular customer needs.
 
 COST OF REVENUES
 
  The Company's cost of service revenues is comprised primarily of the
Company's costs for its nationwide backbone network and local telco loops,
salaries and benefits for the Company's customer service and operations
personnel (including its network engineers, backbone engineers, network
management and systems personnel and installers), and depreciation, rent,
repairs and utilities related to the Company's Internet Data Centers. Cost of
equipment revenues represents the cost to the Company of third-party equipment
sold to customers.
 
  The Company's cost of service revenues increased sequentially each quarter
from $999,000 to $1.8 million to $2.9 million and to $4.5 million in the
quarters ended December 31, 1996 and March 31, June 30 and September 30, 1997,
respectively. Cost of service revenues as a percentage of service revenues
increased sequentially each quarter from 105% to 117% to 130% and to 138% in
the quarters ended December 31, 1996 and March 31, June 30 and September 30,
1997, respectively. These increases in cost of service revenues in absolute
dollars and as a percentage of service revenues were primarily the result of
the opening of additional Internet Data Centers and the costs associated
therewith. The Company expects that its cost of service revenues as a
percentage of service revenues may remain above 100% through at least 1998.
The cost of equipment revenues varied from quarter to quarter, due primarily
to fluctuations in equipment revenues. Cost of equipment revenues as a
percentage of equipment revenues varied from 68% to 77% based on the
particular mix of equipment purchased by customers in a given quarter.
 
 MARKETING AND SALES
 
  The Company's marketing and sales expenses are comprised primarily of
salaries and benefits for the Company's marketing and sales personnel,
printing and advertising costs, consultants' fees and travel and
entertainment. Marketing and sales expenses have increased as a result of
increased marketing and sales personnel, increased advertising, increased
marketing program expenses and other marketing efforts. Marketing and sales
expenses as a percentage of total revenues fluctuated from quarter to quarter
due to the timing of advertising and other promotional activities. The Company
expects that marketing and sales expenses will continue to increase in
absolute dollars during 1998 but will begin to decline as a percentage of
total revenues as recurring revenues from the existing customers, which tend
to have lower marketing and sales expenses associated with them, become a more
significant percentage of total revenues.
 
 GENERAL AND ADMINISTRATIVE
 
  The Company's general and administrative expenses are comprised primarily of
salaries and benefits for the Company's administrative and management
information systems personnel and fees paid for professional services and
recruiting. General and administrative expenses have increased primarily as a
result of additional personnel, recruiting fees and consulting costs. General
and administrative expenses as a percentage of total revenues increased during
the quarters ended March 31 and June 30, 1997 due to increased professional
services and recruiting fees. The Company expects that general and
administrative expenses will continue to increase in absolute dollars but will
begin to decline as a percentage of total revenues as existing overhead is
spread over more substantial operations.
 
 PRODUCT DEVELOPMENT
 
  The Company's product development expenses are comprised primarily of
salaries and benefits for the Company's product development personnel and fees
paid to consultants, all of whom focus
 
                                      28
<PAGE>
 
their efforts primarily on the integration of best-of-breed products and
services developed by leading technology vendors with the Company's services.
With the exception of the quarter ended March 31, 1997, product development
expenses have increased as a result of continuing efforts to integrate best-
of-breed third-party technologies into the Company's service offerings. The
decline in product development expenses in the quarter ended March 31, 1997
reflected a temporary decline in the use of consultants for product
development. Product development expenses as a percentage of total revenues
decreased during 1997 due to a high number of consultants used in product
development during the quarter ended December 31, 1996. The Company expects
that product development expenses will continue to increase in absolute
dollars as the Company makes additional investments in developing its
collaborative management services but will decline as a percentage of total
revenues.
 
 DEFERRED COMPENSATION EXPENSE
 
  In the quarter ended September 30, 1997, the Company recorded deferred stock
compensation of $724,000 in connection with the grant of certain stock options
between April and July 1997, which amount is generally being amortized over
the approximately four year vesting period of such options. This amortization
is being made at a rate of approximately 52% in the first year, 27% in the
second year, 15% in the third year and 6% in the fourth year. The Company
granted additional options in the quarter ended December 31, 1997 and, as a
result, recorded additional deferred stock compensation of approximately $2.8
million in that quarter. Of the total deferred stock compensation,
approximately $85,000 was amortized in the quarter ended September 30, 1997
and an additional $1.0 million will be amortized in the quarter ended
December 31, 1997. The Company expects amortization of approximately $1.3
million during 1998 related to these options. These amortization amounts are
divided among the expense categories discussed above.
 
YEARS ENDED DECEMBER 31, 1995 AND 1996 AND NINE MONTHS ENDED SEPTEMBER 30,
1996 AND 1997
 
 REVENUES
 
  The Company's revenues increased 122% from $1.4 million in 1995 to $3.1
million in 1996 and increased 272% from $2.0 million in the nine months ended
September 30, 1996 to $7.5 million in the nine months ended September 30,
1997. Service revenues increased 130% from $1.1 million in 1995 to $2.5
million in 1996. The growth in the Company's service revenues from 1995 to
1996 resulted primarily from an increase in the number of customers to which
the Company provided Internet connectivity and to a lesser extent from an
increase in service revenues per Internet connectivity customer. As the
Company began to acquire new customers that purchased services in addition to
Internet connectivity and the Company opened its first Internet Data Center in
August 1996, the increase in average total revenues per customer became a more
significant factor in the Company's revenue growth although increases in the
total number of customers continued to be the more important factor. Service
revenues increased 368% from $1.5 million in the nine months ended September
30, 1996 to $7.0 million in the nine months ended September 30, 1997. This
growth in service revenues was primarily the result of opening the Company's
first two Internet Data Centers in August 1996 and March 1997, increases in
the number of new customers and increases in revenues from existing customers.
The Company sells third-party equipment to its customers as an accommodation
to facilitate their purchase of services. The Company's equipment revenues
increased 99% from $340,000 in 1995 to $676,000 in 1996 and decreased 6% from
$520,000 in the nine months ended September 30, 1996 to $489,000 in the nine
months ended September 30, 1997.
 
 COST OF REVENUES
 
  Cost of service revenues increased from $846,000 in 1995 to $2.5 million in
1996 and increased from $1.5 million in the nine months ended September 30,
1996 to $9.2 million in the nine months
 
                                      29
<PAGE>
 
ended September 30, 1997. The Company's cost of service revenues as a
percentage of service revenues increased from 79% in 1995 to 103% in 1996 and
from 103% in the nine months ended September 30, 1996 to 131% in the nine
months ended September 30, 1997. The increases in cost of service revenues in
absolute dollars and as a percentage of service revenues were due to increased
costs associated with the build-out and operation of the Company's increasing
number of Internet Data Centers. Cost of equipment revenues increased from
$282,000 in 1995 to $452,000 in 1996 and from $345,000 in the nine months
ended September 30, 1996 to $361,000 in the nine months ended September 30,
1997. Cost of equipment revenues varies primarily as a result of equipment
revenues and, to a lesser extent, the mix of equipment purchased by customers.
 
 MARKETING AND SALES
 
  The Company's marketing and sales expenses increased from $1.1 million in
1995 to $2.7 million in 1996 and from $1.5 million in the nine months ended
September 30, 1996 to $7.7 million in the nine months ended September 30,
1997. These increases were primarily the result of hiring additional marketing
and sales personnel and expanding marketing programs.
 
 GENERAL AND ADMINISTRATIVE
 
  The Company's general and administrative expenses increased by 147% from
$427,000 in 1995 to $1.1 million in 1996 and from $573,000 in the nine months
ended September 30, 1996 to $3.6 million in the nine months ended September
30, 1997. These increases were primarily the result of increased hiring of
administrative personnel, fees paid for recruiting, costs for consultants and
cost for professional services providers.
 
 PRODUCT DEVELOPMENT
 
  The Company's product development expenses increased from $70,000 in 1995 to
$444,000 in 1996 and from $121,000 in the nine months ended September 30, 1996
to $1.1 million in the nine months ended September 30, 1997. The Company's
product development expenses grew between the comparison periods primarily
because of the addition of product development personnel to support the
Company's expanded service offerings.
 
 NET INTEREST EXPENSE
 
  The Company's net interest expense increased from $38,000 in 1995 to $39,000
in 1996 and from $43,000 in the nine months ended September 30, 1996 to
$242,000 in the nine months ended September 30, 1997. The increases in net
interest expense between the comparison periods were primarily the result of
substantially increased borrowings as the Company entered into equipment loans
and lease agreements to finance the construction of its Internet Data Centers
and working capital lines of credit to finance working capital for its
operations. The Company expects that net interest expense will continue to
grow as the Company enters into additional equipment leases and loans and
obtains additional borrowings for working capital.
 
 DEFERRED COMPENSATION EXPENSE
 
  In the nine months ended September 30, 1997, the Company recorded deferred
stock compensation of $724,000 in connection with the grant of certain stock
options between April and July 1997, which amount is generally being amortized
over the approximately four year vesting period of such options. This
amortization is being made at a rate of approximately 52% in the first year,
27% in the second year, 15% in the third year and 6% in the fourth year. Of
the total deferred stock compensation, $85,000 was amortized in the nine
months ended September 30, 1997. This amount is divided among the expense
categories discussed above.

FACTORS AFFECTING RESULTS OF OPERATIONS
 
  The Company expects to experience significant fluctuations in its future
quarterly and annual results of operations due to a variety of factors, many
of which are outside the Company's control including: demand for and market
acceptance of the Company's services and enhancements; introductions of
services or enhancements by the Company and its competitors; capacity
utilization of its Internet Data Centers; reliable continuity of service and
network availability; the ability to increase bandwidth as necessary; the
timing of customer installations; the mix of services sold by the Company;
customer retention; the timing and success of marketing efforts and service
introductions by the Company; the timing and magnitude of capital
expenditures, including construction costs relating to the expansion of
operations; the timely expansion and existing Internet Data Centers and
completion of new Internet Data Centers; the introduction by third parties of
new Internet and networking technologies; increased competition in the
Company's markets; changes in the pricing policies of the Company and its
competitors; fluctuations in bandwidth used by customers; the retention of key
personnel; economic conditions specific to the Internet industry; and other
general economic factors. In addition, a relatively large portion of the
Company's expenses are fixed in the short-term, particularly with respect to
telecommunications, depreciation, real estate and interest expenses and
personnel, and therefore the Company's results of operations are particularly
sensitive to fluctuations in revenues. Also, if the Company's agreement with
Computer Associates were to terminate and the Company continued to require
Computer Associates' software, the license fees paid by the Company could
increase fixed costs significantly. Furthermore, if the Company were to become
unable to continue leveraging third party products in the Company's services
offerings, the Company's product development costs could increase
significantly. Although the Company has not encountered significant
difficulties in collecting upon accounts receivable in the past, many of the
Company's customers are in an emerging stage, and there can be no assurance
that the Company will be able to collect receivables on a timely basis. For
these and other reasons, in some future quarters, the Company's results of
operations may fall below the expectations of securities analysts or
investors, which could have a material adverse effect on the market price of
the Company's Common Stock.
 
  The market for Internet system and network management solutions has only
recently begun to develop, is evolving rapidly and likely will be
characterized by an increasing number of market entrants. There is significant
uncertainty regarding whether this market ultimately will prove to be viable
or, if it becomes viable, that it will grow. In order to be successful in this
emerging market, the Company must be able to differentiate itself from its
competition through its service offerings, such as its recently introduced
collaborative management and Internet technology services. There can be no
assurance that the Company will be successful in differentiating itself or
achieving market acceptance of its services, or that it will not experience
difficulties that could delay or prevent the successful development,
introduction or marketing of these services. If the Company incurs increased
costs or is unable, for technical or other reasons, to develop and introduce
new services or enhancements of existing services in a timely manner,
including certain collaborative management and Internet technology services
scheduled to be available in the first half of 1998, or if these or other new
products or services do not achieve market acceptance in a timely manner or at
all, the Company's business, results of operations and financial condition
could be materially adversely affected. See "Risk Factors--Dependence on New
Market; Uncertainty of Acceptance of Services."
 
  A component of the Company's long-term strategy is to expand into
international markets, and the Company currently plans to open an Internet
Data Center in the London metropolitan area in the first half of 1998. There
can be no assurance that the Company will be able to market, sell and deliver
successfully its services outside the United States. The Company generally
intends to outsource the initial operation of its international Internet Data
Centers. As a result, the Company will be dependent for a time on third
parties to deliver its services from and manage the operations of such
international Internet Data Centers. In addition to the uncertainty as to the
Company's ability to expand into international markets, there are certain
risks inherent in conducting business internationally, such as
 
                                      31
<PAGE>
 
unexpected changes in regulatory requirements, export restrictions, tariffs
and other trade barriers, challenges in staffing and managing foreign
operations, differing technology standards, employment laws and practices in
foreign countries, longer payment cycles, problems in collecting accounts
receivable, political instability, fluctuations in currency exchange rates,
imposition of currency exchange controls, seasonal reductions in business
activity and potentially adverse tax consequences, any of which could
adversely affect the Company's international operations. In addition, there
can be no assurance that the Company will be able to obtain the necessary
telecommunications infrastructure in a cost-effective manner or compete
effectively in international markets. See "Risk Factors--Risks Associated with
International Operations."
 
  The Company recognizes the need to ensure its operations will not be
adversely impacted by Year 2000 software failures. Software failures due to
processing errors potentially arising from calculations using the year 2000
date are a known risk. The Company has established procedures for evaluating
and managing the risks and costs associated with this problem and estimates
that expenses required to improve computer systems to be Year 2000 compliant
will not be material. However, many of the Company's customers maintain their
Internet operations on UNIX-based servers, which may be impacted by Year 2000
complications. The failure of such servers could have a material adverse
effect on the Company's customers, which in turn could have a material adverse
effect on the Company's business, results of operations and financial
condition.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed its operations primarily through
private sales of Preferred Stock and through various types of equipment loans
and lease lines and working capital lines of credit. At September 30, 1997,
the principal source of liquidity for the Company was $3.9 million of cash and
cash equivalents. As of that date, the Company also had equipment loans and
lease lines and working capital lines of credit under which it could borrow up
to an additional aggregate of $8.0 million for purchases of equipment and for
working capital. In the fourth quarter of 1997, the Company closed an
additional Preferred Stock financing with gross proceeds to the Company of
$7.5 million and entered into additional equipment loan agreements and lines
of credit under which the Company could borrow up to an aggregate of $22
million. See Notes 3 and 8 of Notes to Financial Statements for a description
of the Company's available debt facilities.
 
  Since the Company began to offer server hosting services in 1995, the
Company has had significant negative cash flows from operating activities. Net
cash used for operating activities in 1995, 1996 and the nine months ended
September 30, 1997 was $453,000, $3.0 million and $9.6 million, respectively.
Net cash used for operating activities in each of these periods was primarily
the result of net losses, offset in part by increases in accounts payable,
accrued expenses and depreciation and amortization.
 
  Net cash used for investing activities in 1995, 1996 and the nine months
ended September 30, 1997 was $77,000, $3.6 million and $15.0 million,
respectively. Net cash used for investing activities in these periods was
almost entirely the result of capital expenditures for the construction of
Internet Data Centers, leasehold improvements, furniture and fixtures, and
computers and other equipment.
 
  Cash provided by financing activities in 1995, 1996 and the nine months
ended September 30, 1997 was $692,000, $10.2 million and $24.8 million,
respectively. Of this cash, $9.4 million in 1996 and $16.1 million in the nine
months ended September 30, 1997 resulted from the issuance of Preferred Stock,
net of issuance costs and related warrants, and $490,000, $719,000 and $4.7
million in 1995, 1996 and the nine months ended September 30, 1997 resulted
from debt, bank borrowings and sale-leaseback financings offset by payments
thereon and required restricted deposits.
 
  The Company's capital expenditures for the nine months ended September 30,
1997 were approximately $15.6 million and thereafter through 1998 are expected
to be at least $26 million. Such
 
                                      32
<PAGE>
 
expenditures are primarily for property and equipment. As of September 30,
1997, the Company also had commitments under capital leases and under
noncancellable operating leases of $2.5 million and $17.4 million,
respectively, through 2007. See Note 6 of Notes to Financial Statements. The
Company expects to meet its working capital and capital expenditure
requirements over the next 12 months with existing cash and cash equivalents
and short-term investments, the net proceeds from this offering, cash from
sales of services and proceeds from existing and future equipment loans and
lease lines and working capital lines of credit and possibly other borrowings.
Thereafter, the Company may also need to raise additional funds through public
or private financing, strategic relationships or other arrangements. There can
be no assurance that the Company will be successful in generating sufficient
cash flows from operations or raising capital in sufficient amounts on terms
acceptable to it. The failure of the Company to raise capital when needed
could have a material adverse effect on the Company's business, results of
operations and financial condition. If additional funds are raised through the
issuance of equity securities, the percentage ownership of its then-current
stockholders would be reduced. Furthermore, such equity securities might have
rights, preferences or privileges senior to those of the Company's Common
Stock. See "Risk Factors--Risks Associated with Planned Expansion of the
Exodus Network."
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  The Financial Accounting Standards Board ("FASB") recently issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share." SFAS
No. 128 requires the presentation of basic earnings per share ("EPS") and, for
companies with complex capital structures, diluted EPS. SFAS No. 128 is
effective for annual and interim periods ending after December 15, 1997. The
Company expects that, for profitable periods, basic EPS will be higher than
EPS as presented in the accompanying financial statements and diluted EPS will
not differ materially from EPS as presented in the accompanying financial
statements. Computations for loss periods should not change significantly.
 
  The FASB also recently issued SFAS No. 130, "Reporting Comprehensive
Income." SFAS No. 130 establishes standards for reporting and displaying
comprehensive income and its components in financial statements. It does not,
however, require a specific format, but requires the Company to display an
amount representing total comprehensive income for the period in its financial
statements. The Company is in the process of determining its preferred format.
SFAS No. 130 is effective for fiscal years beginning after December 15, 1997.
 
  The FASB also recently issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for
the way public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises to
report selected information about operating segments in interim financial
reports. SFAS No. 131 is effective for financial statements for periods
beginning after December 31, 1997. The Company has determined that it does not
have any separately reportable business segments.

peering interconnections, provide the foundation for high performance,
availability, scalability and reliability of customers' Internet operations.
The Company's collaborative management services, including performance
monitoring and site management reports, enable customers and the Company to
manage customers' Internet operations jointly, proactively and continuously.
Finally, the Company's Internet technology services, which include security
and content distribution, integrate best-of-breed technologies of leading
vendors with the Company's expertise to provide customers with scalable,
secure and high performing Internet applications. The Company's portfolio of
layered services optimize the development, deployment and proactive management
of enterprises' mission-critical Internet operations.
 
  The Company began offering server hosting services in late 1995, opened its
first dedicated Internet Data Center in August 1996 and introduced its
collaborative management and Internet technology services in 1997. The Company
currently operates six Internet Data Centers, consisting of approximately
90,000 gross square feet, located in five metropolitan areas: Los Angeles, New
York, San Francisco, Seattle and Washington, D.C. The Company intends to
expand domestically and internationally, including the expected addition of an
additional Internet Data Center in the San Francisco metropolitan area and a
new site in the London metropolitan area in the first half of 1998.
 
INDUSTRY BACKGROUND
 
  Use of the Internet, including intranets and extranets, has grown rapidly in
recent years, driven by a number of factors, including the large and growing
installed base of advanced personal computers, improvements in network
architectures, increasing numbers of network-enabled applications, the
emergence of compelling content and commerce-enabling technologies and easier,
faster and cheaper access. International Data Corporation estimates that by
the end of 1997 the number of World Wide Web users worldwide would be
approximately 50 million and will continue to grow to approximately 129
million by the end of 2000. As a result of this growing use, the Internet has
become an important new
 
                                      34
<PAGE>
 
global communications and commerce medium and represents an enormous
opportunity for enterprises to interact in new and different ways with a large
number of customers, employees, suppliers and partners.
 
  Enterprises are responding to this opportunity by rapidly increasing their
investments in Internet sites and services. In the last several years, many
enterprises that focus solely on delivering services over the Internet have
emerged, and, more recently, mainstream businesses have begun to implement
Internet sites and commerce applications. This projected increase in
commercial Internet use should drive rapid growth in revenues from Internet
commerce which, according to International Data Corporation, are expected to
increase from approximately $10 billion in 1997 to approximately $120 billion
in 2000.
 
  As use of the Internet grows, enterprises are increasing the breadth and
depth of their Internet product and service offerings. Pioneering Internet-
based businesses have developed Internet products and services in areas such
as finance, banking, entertainment, education and advertising. In addition,
mainstream businesses have begun to use the Internet for an expanding variety
of applications, ranging from corporate publicity and advertising, to sales,
distribution, customer service, employee training and communication with
business partners. These Internet operations are mission-critical for
virtually all Internet-based businesses and are becoming increasingly mission-
critical for many mainstream enterprises. Loss of the availability of mission-
critical Internet sites often results in losses in revenue and impairment of
customer goodwill. As a result, to ensure the reliability of their mission-
critical Internet operations, enterprises are requiring that these operations
have 24x7 performance, scalability and expert management.
 
  The proliferation of Internet services offered and the growth in mission-
critical Internet applications are driving an increase in the complexity of
commercial Internet sites. In order to ensure the quality, reliability,
availability and redundancy of these Internet operations, corporate IT
departments must make substantial investments in developing Internet expertise
and infrastructure. They need geographically distributed state-of-the-art
facilities and networks that are monitored and managed 24x7 by experts in
Internet technology, can be upgraded to reflect changing technologies and can
be scaled as the needs of enterprises evolve. However, such a continuing
significant investment of resources is often an inefficient use of
enterprises' overall resources. As a result, corporate IT departments are
increasingly seeking collaborative outsourcing arrangements that can increase
performance, provide continuous operation of their Internet solutions and
reduce Internet operating expenses. Forrester Research, Inc. ("Forrester")
estimates that Internet hosting revenues will increase from approximately $200
million in 1997 to almost $8 billion by the year 2000. Furthermore, Forrester
estimates that the broader market for distributed infrastructure services,
which includes Internet hosting as well as wide area network ("WAN")
management, network design and end-user support will grow from approximately
$36 billion in 1997 to approximately $89 billion in 2000.
 
  A variety of companies, such as regional ISPs, national ISPs and large IT
outsourcing firms, offer products and services that attempt to address
enterprises' Internet outsourcing needs. However, the solutions offered by
these companies fail to address certain elements required to ensure that
customers' mission-critical Internet operations are reliable, scalable and
high performing. For example, regional ISPs lack the geographically-
distributed data centers necessary to deliver content using replication or
caching technologies, which are becoming increasingly important as Internet
usage and bandwidth demands increase. National ISPs focus on providing
Internet access and generally have not developed sophisticated and reliable
server management capabilities. In addition, the Company believes that they
often oversubscribe their networks, resulting in poor performance and an
inability to handle effectively customers' sharp increases in bandwidth
demand. The Company believes that neither the regional nor the national ISPs
have developed the systems and application management, monitoring and customer
service capabilities required to support mission-critical Internet operations.
 
                                      35
<PAGE>
 
Finally, large IT outsourcing firms tend to focus on large enterprises that
want to outsource their entire IT infrastructure, not just their Internet
operations. These vendors often lack the network infrastructure and Internet
expertise required to provide mission-critical Internet system and network
management services. As a result, Exodus believes a significant opportunity
exists for a highly-focused company to provide a combination of server
hosting, Internet connectivity, collaborative management and Internet
technology services that will enable reliable, high performance of
enterprises' mission-critical Internet operations.
 
THE EXODUS SOLUTION
 
  Exodus is a leading provider of Internet system and network management
solutions for enterprises with mission-critical Internet operations. Its
server hosting, Internet connectivity, collaborative management and Internet
technology services are designed to provide enterprises with the high
performance, scalability and expertise necessary to optimize their Internet
operations. The Company's tailored solutions are designed to be seamlessly
integrated with existing enterprise systems architectures and enable customers
to outsource the monitoring, administration and optimization of their
equipment, applications and overall Internet operations. The Company believes
that its solutions enable customers to deploy and expand Internet operations
rapidly and cost-effectively, especially when compared to in-house solutions.
The Exodus solution provides the following key advantages to its customers:
 
  HIGH PERFORMANCE. The Company supports enterprises' business objectives by
ensuring that their Internet sites perform effectively. The Company's
solutions provide the availability and reliability that customers need to be
able to depend on the Internet for mission-critical operations. The Company's
solutions are designed to maximize performance through features such as
geographically distributed Internet Data Centers, redundant and high speed
network design, content distribution technologies, security and 24x7
monitoring and diagnosis.
 
  SCALABILITY. The Company's solutions are designed to be flexible and
scalable, ensuring customers a consistently high level of performance as their
Internet operations expand. The Company can quickly scale the amount of
hosting space, power, bandwidth or managed services that a customer receives,
all in a way transparent to the end-user. The Company believes that the
scalability of its solutions is a significant advantage over in-house
solutions.
 
  INTERNET SYSTEMS AND NETWORK MANAGEMENT EXPERTISE. By leveraging the
knowledge gained from supporting many leading-edge Internet operations, the
Company has developed a specialized Internet system and network management
expertise that is difficult for any single customer to replicate in-house.
Customers gain access to the Company's experience in network, system,
application and security management.
 
  COLLABORATIVE AND PROACTIVE MANAGEMENT. The Company believes that
enterprises value Internet service relationships that are collaborative and
proactive. Therefore, the Company has developed a collaborative management
approach that provides customers with detailed monitoring, reporting and
management tools that can be accessed through the Internet to control
customers' Internet hardware, network, software and application environments.
This approach focuses on identifying and resolving potential problems before
they impact an Internet site's availability or performance. Through the
Company's system and network management framework, customers are able to
manage both mission-critical Internet operations housed at the Company's
Internet Data Centers and in-house IT applications. The Company believes that
this provides an important advantage to enterprises that seek to outsource a
portion of their Internet operations and to link the management of the
outsourced operations with in-house operations.
 
                                      36
<PAGE>
 
  COST-EFFECTIVE SOLUTION. The Company's customers benefit from leveraging the
significant capital, operating and labor investments that the Company has made
to support distributed, mission-critical Internet operations. Most enterprises
today do not have the infrastructure that mission-critical Internet operations
require, including data centers located adjacent to major Internet connection
points, 24x7 operations and specialized Internet technology expertise. The
Company believes that its solutions to optimize enterprises' Internet
operations are significantly more cost-effective than most in-house solutions.
 
THE EXODUS STRATEGY
 
  The Company's 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, the Company's strategy
includes the following key elements:
 
  EXTEND MARKET LEADERSHIP. The Company has played a leading role in creating
and defining the market for Internet system and network management solutions
and plans to establish itself as the brand name and leader in this market. The
Company believes that its highly-focused approach to serving this market
provides it with an advantage over competitors that also serve the entry-level
hosting market or the stand-alone Internet access market. The Company plans to
extend its leadership in the market for Internet system and network management
solutions both by aggressively continuing to expand its base of more than 180
Internet Data Center customers and by capitalizing on the growth of its
customers' needs for these solutions.
 
  FOCUS ON COLLABORATIVE MANAGEMENT AND INTERNET TECHNOLOGY SERVICES. The
Company believes that developing new services to manage enterprises' mission-
critical Internet operations jointly, proactively and continuously will offer
a compelling value proposition to its customers. The Company has invested and
is continuing to invest in services that will ensure high availability and
performance of customers' Internet-based applications, including systems
administration, disaster recovery, security and systems and network
management. As part of this strategy, the Company has developed and intends to
continue to develop relationships with providers of leading Internet
technologies in order to enhance its service offerings and meet its customers'
evolving needs.
 
  CONTINUE DOMESTIC EXPANSION AND ESTABLISH GLOBAL PRESENCE. The Company is
continuing to build Internet Data Centers and expand direct sales coverage in
the United States and is also pursuing international opportunities. The
Company believes that having a number of widely distributed and networked
Internet Data Centers improves network performance and enhances overall site
redundancy. In addition, the Company's experience indicates that locating an
Internet Data Center within a geographic region can significantly enhance its
ability to attract new customers in that region. The Company intends to expand
domestically and internationally, including the expected addition of Internet
Data Centers in the London metropolitan area and an additional site in the San
Francisco metropolitan area in the first half of 1998.
 
  LEVERAGE EXPERTISE TO ADDRESS NEW MARKET OPPORTUNITIES. The Company intends
to leverage its significant achievements with pioneering Internet-based
businesses to address broader customer markets, such as e-commerce and
extranets. For example, mainstream corporations are increasingly establishing
extranets with suppliers and customers. However, many of these enterprises
lack the infrastructure and Internet expertise required to operate effectively
mission-critical Internet applications and are looking for collaborative
management assistance. The Company believes that its Internet system and
network management solutions can support the business needs of these
mainstream corporations by enabling them to deploy mission-critical extranet
operations successfully.
 
  ESTABLISH STRATEGIC RELATIONSHIPS FOR TECHNOLOGY AND DISTRIBUTION. The
Company is establishing strategic relationships for technology and
distribution. The Company believes that
 
                                      37
<PAGE>
 
establishing relationships with technology developers enables it to leverage
these enterprises' research and development expertise cost-effectively. These
relationships allow the Company to gain more rapid access to new technologies
and to provide value-added integrated solutions for its customers. For
example, the Company has worked closely with Computer Associates to develop
certain of the Company's collaborative management services using Computer
Associates' Unicenter(R) TNG(TM) technology. The Company's product development
personnel will continue to develop vendor relationships and technology-based
relationships, such as those with Raptor Systems, Inc., VeriFone, Inc. and
CheckPoint Software Technologies Limited, to enhance the Company's solutions.
In addition, the Company currently has distribution alliances with a number of
companies including Automatic Data Processing, Inc., Computer Associates, GE
Capital Services, InfoNet Services Corporation and Poppe Tyson, Inc. and
believes it can expand its customer base by establishing additional
distribution relationships with content developers, system integrators, system
vendors, consulting companies and ISPs.
 
SERVICES
 
  The Company's services are designed to provide enterprises with the high
performance, scalability and expertise they need to optimize their mission-
critical Internet operations. The Company creates tailored solutions for its
customers based on their unique business and technical requirements, modifying
the services as customers' needs evolve. The services are delivered from
geographically distributed, state-of-the-art Internet Data Centers and include
server hosting, Internet connectivity, collaborative management and Internet
technology services. The server hosting and Internet connectivity services
provide the foundation for high performance, availability, scalability and
reliability of customers' Internet operations. The collaborative management
services enable customers and the Company to manage customers' Internet
operations jointly, proactively and continuously. The Internet technology
services integrate best-of-breed technologies of leading vendors with the
Company's expertise to build scalable, secure and high performing Internet
applications. These services can be layered to allow customers to outsource an
increasing portion of the management of their Internet operations. Customers
pay monthly fees for the services utilized, as well as one-time fees for
installation and for any equipment purchased from the Company.
 
 SERVER HOSTING
 
  The Company provides a broad range of server hosting services tailored to
meet the unique demands of sophisticated, multi-vendor mission-critical
Internet operations. The Company supports all leading Internet hardware and
software systems vendor platforms, including those from Compaq Computer
Corporation, Dell Computer Corporation, Hewlett-Packard Company, IBM,
Microsoft Corporation, Silicon Graphics, Inc., Sun Microsystems, Inc. and The
Santa Cruz Operation, Inc. This multi-vendor flexibility enables the customer
to retain complete control over the technical solution and enables its
Internet operations to be integrated into 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 always has access to additional server hosting
services.
 
  Customers can select from shared rack facilities, highly secure cabinets or
enclosed cage facilities based upon their business and technical requirements.
Most server hosting facilities include dedicated electrical power circuits to
ensure that each customer's electrical power requirements are met. Each
Internet Data Center is constructed based upon the requirements of high-
availability mission-critical computing 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.

 INTERNET CONNECTIVITY
 
  The Company's Internet connectivity services are designed to deliver the
scalability, high availability and performance required by high-volume,
mission-critical Internet operations. Since enterprises' mission-critical
Internet operations often experience network traffic spikes due to promotions
or events, the Company has a policy of under-subscribing its network by
provisioning significant excess capacity. In addition, customers can purchase
spare capacity and pay only for the bandwidth that is used.
 
  To meet customers' requirements of near 100% availability, the Company's
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. The Company maintains multiple network links from multiple vendors
into each Internet connection point and regularly checks that its fiber
backbone is traversing physically-separated paths. Customers also enhance
their Internet site's availability by physically duplicating their site within
multiple Internet Data Centers and then synchronizing applications and content
via the Company's private fiber backbone network. This network architecture
optimizes the availability of a customer's site, even in the event of a link
failure.
 
                                      39
<PAGE>
 
  The Company's Internet connectivity services are also designed to
consistently deliver low-latency and peak network performance. The Company's
backbone engineering personnel continuously monitor traffic patterns and
congestion points throughout the Internet and dynamically reroute traffic
flows to optimize end-user response times. The Company also provides peak
network performance by maintaining what it believes is one of the largest
number of direct public and private network peering interconnections in the
industry. The Company's network includes private peering interconnections with
eight national ISPs and public peering interconnections with over 120 ISPs,
including many of the largest providers.
 
  For customers seeking a direct communications link to the site of another
customer that is located at the same Internet Data Center, the Company offers
highly secure, fast and efficient cross-connections.
 
 COLLABORATIVE MANAGEMENT
 
  The Company's collaborative management services support mission-critical
Internet operations by providing the customer with detailed monitoring,
reporting and management tools to control their hardware, network, software
and application environments. Through the Company's system and network
management framework, customers are able to manage both mission-critical
Internet operations housed at the Company's Internet Data Centers and in-house
IT applications. The Company believes that this provides an important
advantage to enterprises that seek to outsource a portion of their Internet
operations and to link the management of the outsourced operations with in-
house operations. The Company's proactive service methodology focuses on
identifying and resolving potential problems before they ever impact an
Internet site's availability or performance. The Company's sophisticated
Internet system and network management solutions enable the Company to
identify and to begin to resolve hardware, software, network and application
problems, frequently before the customer is even aware that a problem exists.
The Company offers the services summarized in the following chart:

CUSTOMERS
 
  The Company has 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, 1997, the Company had over 180
Internet Data Center customers, including the following:
 
Applied Materials,    Hotmail Corporation            The Santa Cruz
 Inc.                 Inktomi Corporation             Operation, Inc.

  The Company's contracts with its customers generally cover the provision of
services by the Company for a one year period and may contain, among other
things, certain service level guarantees. See "Risk Factors--Risk of System
Failure."
 
  The following examples illustrate how the Company's customers use its server
hosting, Internet connectivity, collaborative management and Internet
technology services.
 
 GEOCITIES
 
  In 1997, GeoCities, a leading provider of free home pages on the Internet,
selected the Company to colocate its Internet servers and administer its
rapidly growing Internet computing requirements. GeoCities is one of the most
frequently visited sites on the Internet measuring over 100 million hits a day
on a peak day, and GeoCities relied heavily upon the Company's advanced
professional services capabilities to plan and manage the successful migration
of the GeoCities site into Exodus' Internet Data Center facilities. This
migration posed unique challenges, including minimizing downtime for GeoCities'
more than one million "homesteaders" (users), physically migrating more than 45
Internet servers and shifting in real-time the network routing of more than 160
Mbps of sustained Internet traffic. The Company currently provides GeoCities
and its users reliable connectivity, scalable bandwidth and 24x7 monitoring,
systems administration and disaster recovery services.
 
 HOTMAIL CORPORATION
 
  In 1996, Hotmail Corporation ("Hotmail"), a leading provider of globally-
accessible, free Web-based electronic mail, engaged the Company to host its
Internet servers to gain access to greater bandwidth to support Hotmail's
growing customer base. Hotmail's primary challenge was to find a company that
could support the significant growth that it was anticipating for its services.
Hotmail selected the Company, based upon the scalability and high performance
of the Company's Internet Data Center and network solutions, as well as on the
Company's reputation for high quality customer service. Within a year of
colocating its Internet site at the Company's Internet Data Center, Hotmail's
subscriber base has grown from 400,000 to over 10 million, the number of
servers required to operate its site has expanded from 16 to 200, and Hotmail's
sustained network traffic has grown from 10 Mbps to 140 Mbps. The Company
currently manages Hotmail's Web site daily and provides it with the flexibility
for expansion, additional technical support and bandwidth capacity that can be
increased to keep pace with Hotmail's growing subscriber base.

 NATIONAL SEMICONDUCTOR CORPORATION
 
  In 1997, National Semiconductor Corporation ("National"), a global
semiconductor manufacturer, selected the Company for its application
management expertise. National depends on a Java-based e-commerce application
on its Internet site to sell components. This application reduces the time it
takes for customers to determine which components they need, and National
views it as a competitive advantage. Exodus provides the systems
administration, hardware maintenance and tape back-up necessary to manage this
application and to keep it available. National's Internet site serves a broad
array of additional functions, and use of it has grown significantly in the
last 18 months to a few hundred thousand hits per day.
 
 HEARST NEW MEDIA
 
  In 1997, Hearst New Media ("Hearst"), the interactive arm of Hearst
Publishing, decided to colocate in the Company's Internet Data Center located
in the New York metropolitan area its "homearts.com" Website, which is a
leading site for women on the Web. Hearst chose the Company for its 24x7
monitoring services and its array of management services. Hearst's objective
was to improve network performance, monitoring and system management
capabilities, thereby allowing Hearst to focus on further refinement and
expansion of the site. The Company now monitors Hearst's systems through its
Unicenter(R) TNG(TM)-based services and sends Hearst frequent Web-based
reports that track the status of over 40 Hearst Web sites by their domain name
server, reducing possible downtime or poor response time.
 
SALES, DISTRIBUTION AND MARKETING
 
  The Company's sales, distribution and marketing objective is to achieve
broad market penetration by targeting enterprises that depend upon the
Internet for mission-critical operations. As of December 31, 1997, the Company
had 86 employees engaged in sales, distribution and marketing.
 
  The Company sells its services to enterprises directly through its sales
force and indirectly through its channel partners. The Company is actively
seeking to increase its 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. Currently, most of the Company's
sales are derived through the efforts of its sales force. The Company's sales
force is organized into three separate groups, consisting of field sales,
strategic accounts and telesales, each of which is further divided into four
geographical regions within the United States. Sales engineers and client
integration engineers support the Company's sales force, providing pre- and
post-sales support to ensure that customer services are implemented properly
and efficiently.
 
  The Company's sales force is also developing an indirect sales channel for
the Company's products by targeting content developers, system integrators,
system vendors, consulting companies and ISPs. The Company currently has
distribution alliances with a number of companies, including Automatic Data
Processing, Inc., Computer Associates, GE Capital Services, InfoNet Services
Corporation and Poppe Tyson, Inc., and intends to expand its distribution
relationships in the future. The Company's channel partners typically receive
referral fees for bringing customers to the Company.
 
  The Company's marketing organization is responsible for product management,
public relations and marketing communications. Product management includes
defining the product roadmap and bringing to market the portfolio of services
and programs that will enable the Company to meet its business objectives.
These activities include product strategy and definition, pricing, competitive
analysis, product launches, channel program management and product lifecycle
project management. The Company stimulates product demand through a broad
range of marketing communications and public relations activities. Primary
marketing communications vehicles include collateral, advertising, trade
shows, direct response programs, event sponsorship and management of the
Company's Web
 
                                      44

site. Public relations focuses on cultivating industry analyst and media
relationships with the goal of securing broad media coverage and public
recognition of the Company's leadership position in the market for Internet
system and network management solutions.
 
CUSTOMER SERVICE
 
  The Company offers superior customer service by understanding the technical
requirements and business objectives of its customers and fulfilling their
needs proactively on an individual basis. By working closely with its
customers, the Company is able to optimize the performance of its customers'
Internet operations, avoid downtime, resolve quickly any problems that may
arise and make appropriate adjustments in services as customer needs change
over time.  As the Company works with its customers over time, it solicits
their feedback to ensure that it is offering the appropriate types and quality
of service. The Company uses advanced software tools to aid in its customer
monitoring and service efforts. Many customer service employees have been
specifically trained and, as appropriate, certified by the vendors of the
Company's software tools, including Sun Microsystems, Inc., Microsoft
Corporation, Oracle Corporation and Computer Associates.
 
  Customer service begins before a sale, when the Company provides technical
support for complex orders. During the installation phase, the Company assigns
a transition team and a project manager, who also retains responsibility for
the account after installation, to assist the new customer with the
installation process. In addition, the Company provides system integration
services between the customer's Web site and legacy systems. After
installation, the primary customer support area is each Internet Data Center's
Network Control Center, which is operated 24x7 by engineers who answer
customer calls, monitor site and network operations and activate teams to
solve problems that arise. To solve complex problems, the Company draws on the
collective expertise at all of its Internet Data Centers, creating a
nationwide engineering pool. The Company's customer service personnel are also
available to assist customers whose operations require specialized procedures.
 
  Finally, the Company employs network engineers who collaborate with a
customer to design and maintain the LAN environment within the Internet Data
Center and integrate the customer's home LAN and WAN with its Internet site.
The network engineers are trained on NT and Solaris and other UNIX platforms
as well as Cisco routers and switches, and they serve as the second level of
support for customer issues that cannot be resolved by the Network Control
Center. The Company also employs a group of backbone engineers who are
responsible for designing the network that connects the Company's Internet
Data Centers. This group constantly monitors the network design and
effectiveness to optimize performance for customers, rerouting and redesigning
traffic as conditions require.
 
  As of December 31, 1997, the Company had 93 employees dedicated to customer
service and network and backbone engineering.
 
NETWORK DESIGN
 
  The Company's high performance server network is designed to provide the
highest possible availability in order to enable its customers to achieve
reliable Internet operations. It is comprised of the Company's six Internet
Data Centers interconnected by a high-performance network backbone ring and
connected to the Internet through public peering interconnections and private
peering interconnections. Within each Internet Data Center, a virtual LAN
environment provides redundant, high-speed internal connectivity.
 
  The Company's 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-3c links, provisioned by Teleport Communications Group
Inc., MFS Communications Company, Inc., Brooks Fiber Properties, Inc. and
 
                                      45
<PAGE>
 
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 for high redundancy, performance and
capacity, and to perform real-time content replication or caching across its
Internet Data Centers, the Company has multiple clear channel DS-3 links
interconnecting the Internet Data Centers. The Company has engineered its
backbone with a geographically diverse fiber path to provide high
availability, even in the event of a link failure. The Company is planning to
upgrade to an OC-3c backbone in order to accommodate expected traffic growth.
For customers with servers located at multiple Internet Data Centers, the
Company is developing dynamic response time and load balancing technologies
for optimal routing.
 
  Within each Internet Data Center, the Company deploys a virtual LAN
environment to increase reliability and performance and provides customers
with redundant connectivity to the Exodus backbone and the Internet. DS-3 and
OC-3c lines are strategically placed on different routers to avoid any single
points of failure. See "Risk Factors--Dependence on Third-Party Suppliers."
The Company uses a combination of public and private peering interconnections
to achieve fast and reliable delivery of content. It has private peering
interconnections with eight national ISPs, public peering interconnections
with over 120 ISPs, including many of the largest providers, and a presence at
each of the major U.S. IXPs. The Company will continue to work with ISPs to
establish direct private peering interconnections at each of its Internet Data
Centers to provide low latency content delivery. This 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. The Company has a general policy of keeping significant
unutilized network capacity for every LAN, WAN and public and private peering
link to allow for spikes in demand or line outages. As a result, when the
sustained utilized capacity of the link approaches 50%, the Company begins to
plan for the expansion of its available capacity.
 
  If the carriers that operate the IXPs were to discontinue their support of
the peering points and no alternative providers emerged, or such alternative
providers increased the cost of utilizing the IXPs, the distribution of
content through the IXPs, including content distributed by the Company, would
be significantly constrained. Furthermore, as traffic through the IXPs
increases, if commensurate increases in bandwidth are not added, the Company's
ability to distribute content rapidly and reliably through these networks will
be adversely affected. Many of the operators of the private peering
interconnections are competitors of the Company. Currently, the Company does
not pay a fee for many of these interconnections, and if these organizations
were to begin to charge the Company for utilizing these interconnections, or,
in the cases where the Company currently pays a fee, to increase the pricing
associated with utilizing these interconnections, the Company may be required
to identify alternative methods through which it can distribute its customers'
content. See "Risk Factors--Dependence Upon Network Infrastructure."
 
  The Company must continue to expand and adapt its network infrastructure as
the number of users and the amount of information they wish to transport
increase and to meet changing customer requirements. The expansion and
adaptation of the Company's telecommunications infrastructure will require
substantial financial, operational and management resources as the Company
negotiates telecommunications capacity with its existing and other network
infrastructure suppliers. Due to the limited deployment of the Company's
services to date, the ability of the Company's network to connect and manage a
substantially larger number of customers at high transmission speeds is as yet
unknown, and the Company faces risks related to its ability to scale up the
network to its expected customer levels while maintaining superior
performance. In addition, as the Company upgrades its telecommunications
infrastructure to increase bandwidth available to its customers, it is likely
to encounter a certain level of equipment or software incompatibility which
may cause delays in implementation. See "Risk Factors--Unproven Network
Scalability."
 
                                      46
<PAGE>
 
  The Company's operations are dependent upon its ability to protect its
network infrastructure and customers' equipment against damage from human
error, fire, earthquakes, floods, power loss, telecommunications failures,
sabotage, intentional acts of vandalism and similar events. Despite
precautions taken by, and planned to be taken by the Company, the occurrence
of a natural disaster or other unanticipated problems at one or more of the
Company's Internet Data Centers could result in interruptions in the services
provided by the Company or significant damage to customer equipment. In
addition, failure of any of the Company's telecommunications providers, such
as WorldCom, to provide the data communications capacity required by the
Company, as a result of human error, a natural disaster or other operational
disruption, could result in interruptions in the Company's services. See "Risk
Factors--Risk of System Failure."
 
  The increased use of the Internet for retrieving, sharing and transferring
information among businesses, consumers, suppliers and partners has only
recently begun to develop, and the Company's 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
the Company's services. The recent growth in the use of the Internet has
caused frequent periods of performance degradation, requiring the upgrade of
routers, 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 the Company's services. Potentially
increased performance provided by the services of the Company and others is
ultimately limited by and reliant upon the speed and reliability of the
networks operated by third parties. Consequently, the emergence and growth of
the market for the Company's services is dependent on improvements being made
to the entire Internet infrastructure to alleviate overloading and congestion.
See "Risk Factors--Dependence on the Internet and Internet Infrastructure
Development."
 
  A significant barrier to electronic commerce and communications is the
secure transmission of confidential information over public networks. Certain
of the Company's services rely on encryption and authentication technology
licensed from third parties to provide the security and authentication
necessary to effect secure transmission of confidential information. Despite
the Company's design and implementation of a variety of network security
measures, there can be no assurance that unauthorized access, computer
viruses, accidental or intentional actions and other disruptions will not
occur. See "Risk Factors--System Security Risks."
 
PRODUCT DEVELOPMENT
 
  The Company's product development group is primarily responsible for
evaluating and integrating best-of-breed technologies with the Company's
service offerings to support its customers' mission-critical Internet
operations. The Company believes that establishing relationships with
technology enterprises enables it to leverage these enterprises' research and
development expertise. These relationships allow the Company to gain quicker
access to new technologies and to provide value-added integrated solutions for
its customers. For example, the Company has worked very closely with Computer
Associates, including having dedicated Computer Associates engineers located
at the Company, to develop certain of the Company's collaborative management
services using Computer Associates' Unicenter(R) TNG(TM) technology. See "--
Relationship with Computer Associates." The Company's product development
personnel will continue to develop strategic relationships, such as the one
with Computer Associates, and vendor and technology-based relationships, such
as those it has with Raptor Systems, Inc., VeriFone, Inc. and Checkpoint
Software Technologies Limited, to enhance the Company's services through the
integration of leading technologies. To the extent that the Company is unable
to obtain the technology necessary to meet its customers' needs from a third
party, the Company may need to develop the technology itself. As of December
31, 1997, the Company employed 10 persons in product development.
 
                                      47
<PAGE>
 
  The Company's future success will depend, in part, on its ability to offer
services that incorporate leading technology, address the increasingly
sophisticated and varied needs of its current and prospective customers and
respond to technological advances and emerging industry standards and
practices on a timely and cost-effective basis. The market for the Company's
services is characterized by rapidly changing and unproven technology,
evolving industry standards, changes in customer needs, emerging competition
and frequent new service introductions. There can be no assurance that future
advances in technology will be beneficial to, or compatible with, the
Company's business or that the Company will be able to incorporate such
advances on a cost-effective and timely basis into its business. Moreover,
technological advances may have the effect of encouraging certain of the
Company's current or future customers to rely on in-house personnel and
equipment to furnish the services currently provided by the Company. In
addition, keeping pace with technological advances in the Company's industry
may require substantial expenditures and lead time.
 
  The Company incurred $70,000, $444,000 and $1.1 million in product
development expenses during the years ended December 31, 1995 and 1996 and the
first nine months of 1997.
 
RELATIONSHIP WITH COMPUTER ASSOCIATES
 
  The Company has a strategic relationship with Computer Associates
encompassing sales, marketing, operations and engineering. Under the terms of
the Company's agreement with Computer Associates, the Company is deploying the
Unicenter(R) TNG(TM) systems, network and application management software
products to manage the Company's customer service operations and to monitor
its customers' Internet solutions. The Unicenter technology is the Company's
primary enterprise management tool and is the technology on which many of the
Company's value-added services are and will be based. To facilitate the
Company's deployment of Unicenter TNG, Computer Associates has located
dedicated software engineers at the Company. By becoming one of the leading
Unicenter TNG implementations, the Company has also become a primary reference
account for Computer Associates' extensive sales force, which has also created
opportunities for the Company to market its services actively into large
enterprises.
 
  Under the agreement with Computer Associates, to the extent that Computer
Associates offers software that includes functionality that the Company wants
to provide in its service offerings, the Company must generally utilize the
software offered by Computer Associates, as long as such software meets the
Company's requirements. Either party may terminate this agreement upon 60
days' prior written notice. Should Computer Associates or the Company decide
to terminate this agreement, the Company has the right to continue licensing
software from Computer Associates at a discount for five years. During the
term of the agreement, the Company is obligated to pay Computer Associates a
royalty based on the Company's gross revenues.
 
COMPETITION
 
  The market served by the Company is highly competitive. There are few
substantial barriers to entry, and the Company expects that it 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 expertise, customer service, network capability,
reliability, quality of service and scalability, broad geographic presence,
brand name, technical expertise and functionality, the variety of services
offered, the ability to maintain and expand distribution channels, customer
support, price, the timing of introductions of new services, network security,
financial resources and conformity with industry standards. There can be no
assurance that the Company will have the resources or expertise to compete
successfully in the future.
 
  The Company's current and potential competitors in the market include: (i)
providers of server hosting services; (ii) national and regional ISPs; (iii)
global, regional and local telecommunications
 
                                      48
<PAGE>
 
companies and RBOCs; and (iv) large IT outsourcing firms. The Company's
competitors may operate in one or more of these areas and include companies
such as certain subsidiaries of GTE Corporation and WorldCom, IBM and certain
business units of GlobalCenter, which recently announced its proposed
acquisition by Frontier Corporation.
 
  Many of the Company's competitors have substantially greater financial,
technical and marketing resources, larger customer bases, longer operating
histories, greater name recognition and more established relationships in the
industry than the Company. As a result, certain of these competitors may be
able to develop and expand their network infrastructures and service offerings
more quickly, adapt to new or emerging technologies and changes in customer
requirements more quickly, take advantage of acquisition and other
opportunities more readily, devote greater resources to the marketing and sale
of their products and adopt more aggressive pricing policies than can the
Company. In addition, these competitors have entered and will likely continue
to enter into joint ventures or consortiums to provide additional services
competitive with those provided by the Company.
 
  Certain of the Company's 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 the Company's. There
can be no assurance that the Company will be able to offset the effects of any
such price reductions. In addition, the Company believes that the businesses
in which the Company competes are likely to encounter consolidation in the
near future, which could result in increased price and other competition that
could have a material adverse effect on the Company's business, results of
operations and financial condition.
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company relies on a combination of copyright, trademark, service mark
and trade secret laws and contractual restrictions to establish and protect
certain proprietary rights in its products and services. The Company has no
patented technology that would preclude or inhibit competitors from entering
the Company's market. The Company has entered into confidentiality and
invention assignment agreements with its employees, and nondisclosure
agreements with its suppliers, distributors and appropriate customers in order
to limit access to and disclosure of its proprietary information. There can be
no assurance that these contractual arrangements or the other steps taken by
the Company to protect its intellectual property will prove sufficient to
prevent misappropriation of the Company's technology or to deter independent
third-party development of similar technologies. The laws of certain foreign
countries may not protect the Company's products, services or intellectual
property rights to the same extent as do the laws of the United States. The
Company also relies on certain technologies that it licenses from third
parties, such as Computer Associates. See "Risk Factors--Dependence on Third-
Party Suppliers." There can be no assurance that these third-party technology
licenses will continue to be available to the Company on commercially
reasonable terms. The loss of such technology could require the Company to
obtain substitute technology of lower quality or performance standards or at
greater cost, which could materially adversely affect the Company's business,
results of operations and financial condition.
 
  To date, the Company has not been notified that the Company's products
infringe the proprietary rights of third parties, but there can be no
assurance that third parties will not claim infringement by the Company with
respect to current or future products. The Company expects that participants
in its markets will be increasingly subject to infringement claims as the
number of products and competitors in the Company's industry segment grows.
Any such claim, whether meritorious or not, could be time consuming, result in
costly litigation, cause product installation delays or require the Company to
enter into royalty or licensing agreements. Such royalty or licensing
agreements might not be available on terms acceptable to the Company or at
all. As a result, any such claim could have a material adverse effect upon the
Company's business, results of operations and financial condition.
 
                                      49

GOVERNMENT REGULATION
 
  The Company is not currently subject to direct federal, state or local
government regulation, other than regulations applicable to businesses
generally. There is currently only a small body of laws and regulations
directly applicable to access to or commerce on the Internet. However, due to
the increasing popularity and use of the Internet, it is possible that a
number of laws and regulations may be adopted at the federal, state and local
levels with respect to the Internet, covering issues such as user privacy,
freedom of expression, pricing, characteristics and quality of products and
services, taxation, advertising, intellectual property rights, information
security and the convergence of traditional telecommunications services with
Internet communications. The adoption of any such laws or regulations might
decrease the growth of the Internet, which in turn could decrease the demand
for the services of the Company or increase the cost of doing business or in
some other manner have a material adverse effect on the Company's business,
results of operations or financial condition. In addition, applicability to
the Internet of existing laws governing issues such as property ownership,
copyrights and other intellectual property issues, taxation, libel, obscenity
and personal privacy is uncertain. The vast majority of such laws were adopted
prior to the advent of the Internet and related technologies and, as a result,
do not contemplate or address the unique issues of the Internet and related
technologies. In addition, as the Company's services are available over the
Internet in multiple states and foreign countries, and as the Company
facilitates sales by its customers to end users located in such states and
foreign countries, such jurisdictions may claim that the Company is required
to qualify to do business as a foreign corporation in each such state or
foreign country. The Company is qualified to do business in only a limited
number of states, and failure by the Company to qualify as a foreign
corporation in a jurisdiction where it is required to do so could subject the
Company to taxes and penalties for the failure to qualify and could result in
the inability of the Company to enforce contracts in such jurisdictions. See
"Risk Factors--Governmental Regulation."
 
  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. It is possible that claims could be made
against online services companies and Internet access providers under both
United States and foreign law for defamation, negligence, copyright or
trademark infringement, or other theories based on the nature and content of
the materials disseminated through their networks. Several private lawsuits
seeking to impose such liability upon online services companies and Internet
network providers are currently pending. Certain businesses, organizations and
individuals have in the past sent unsolicited commercial e-mails from servers
hosted at the Company's facilities to massive numbers of people, typically to
advertise products or services. This practice, known as "spamming," can lead
to complaints against service providers that enable such activities,
particularly where recipients view the materials received as offensive. In
addition, certain ISPs and other online services companies could deny network
access to companies that allow undesired content or spamming to be transmitted
through their networks. The Company has in the past received, and may in the
future receive, letters from recipients of information transmitted by the
Company's customers objecting to such transmission. Although the Company
prohibits its customers by contract from spamming, there can be no assurance
that its customers will not engage in this practice, which could have a
material adverse effect on the Company's business, results of operations and
financial condition. See "Risk Factors--Risks Associated With Information
Disseminated Through the Company's Network."
 
EMPLOYEES
 
  As of December 31, 1997, the Company had 220 employees, including 86 people
in sales, distribution and marketing, 10 people in product development, 93
people in customer service and network and backbone engineering and 31 people
in finance and administration. The Company believes that its future success
will depend in part on its continued ability to attract, hire and retain
qualified personnel. The competition for such personnel is intense, and there
can be no assurance that
 
                                      50
<PAGE>
 
the Company will be able to identify, attract and retain such personnel in the
future. None of the Company's employees is represented by a labor union, and
management believes that its employee relations are good. See "Risk Factors--
Dependence on Key Personnel" and "--Management of Growth."
 
FACILITIES
 
  The Company's executive offices are located in Santa Clara, California and
consist of approximately 36,000 square feet that are leased pursuant to an
agreement that expires in 2002. The Company leases the facilities for its
current Internet Data Centers in the following metropolitan areas and specific
cities, which cover an aggregate of approximately 90,000 gross square feet and
expire in the years indicated below:

</TABLE>
 
  Most of the Company's leases provide for a renewal option upon the
expiration of the initial term. The Company currently maintains sales offices
in unutilized space in its Internet Data Centers. The Company intends to
expand domestically and internationally, including the expected addition of an
additional Internet Data Center in the San Francisco metropolitan area and a
new site in the London metropolitan area in the first half of 1998. The
Company has recently entered into a lease for the space needed for the
additional site in the San Francisco metropolitan area which covers 55,000
square feet and expires in 2009. The Company believes that it will be able to
lease the additional space required for the London facility on commercially
reasonable terms.
 
LEGAL PROCEEDINGS
 
  On July 30, 1997, Michael Blackman ("Blackman"), a consultant to the Company
from October 1996 through January 1997, filed a complaint against the Company
in the Superior Court for the State of California in and for the County of
Santa Clara alleging damages suffered as a result of the Company's failure to
grant Blackman stock options for the Company's Common Stock as additional
compensation for consulting work he performed for the Company pursuant to an
alleged oral contract between Blackman and another consultant to the Company.
The Company believes that the suit is without merit and intends to contest the
suit vigorously. However, litigation is subject to inherent uncertainties,
and, therefore, there can be no assurance that this lawsuit will be resolved
in the Company's favor.

meetings of the Board. In December 1995 and October 1996, Mr. Rekhi and Mr.

19,841 shares of Series B1 Preferred Stock (convertible into shares of Common

the Board. In addition, in October 1996, Mr. Howley was granted an option to
purchase 25,000 shares of Common Stock at an exercise price of $0.30 per
share, in connection with his service on the Board. In November 1997, Mr.
Rekhi exercised the Common Stock warrant in full. In October 1997, Mr. Howley
exercised the warrant for Series B1 Preferred Stock in full and exercised the
option for 13,000 shares of Common Stock.
 
  In January 1998, the Board adopted, subject to stockholder approval, 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.
Members of the Board who are not employees of the Company, or any parent or
subsidiary of the Company, are eligible to participate in the Directors Plan.
Each eligible director who first becomes a member of the Board on or after the
public offering ("Effective Date") will initially be granted an option for
20,000 shares (an "Initial Grant") on the later of the Effective Date or the
date such director first becomes a director. At each annual meeting of
stockholders thereafter, each eligible director will automatically be granted
an additional option to purchase 5,000 shares (an "Annual Grant") if such
director has served continuously as a member of the Board since the date of
such director's Initial Grant (or since the Effective Date if such director
did not receive an Initial Grant). Initial Grants will vest as to 33 1/3% of
the total shares on each annual anniversary of the date of grant,
 
                                      54
<PAGE>
 
provided the optionee continues as a member of the Board or as a consultant to
the Company. Annual Grants will vest as to 25% of the total shares on each
annual anniversary of the date of grant, provided the optionee continues as a
member of the Board or as a consultant to the Company. Options will cease
vesting once the individual ceases to provide services as a director or
consultant. Following the individual's cessation of services to the Company,
he or she will have seven months in which to exercise their options granted
under the Directors Plan, twelve months if the cessation of services resulted
from the individual's death or disability. The exercise price of all options
granted under the Directors Plan will be the fair market value of the Common
Stock on the date of grant.

  EXECUTIVE EMPLOYMENT POLICY. In December 1997, the Board adopted a form of
Executive Employment Policy (the "Policy") to be entered into between the
Company and each of its executive officers and certain other officers of the
Company (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) of the Company, each Executive's base
salary and medical benefits would continue as follows: Chief Executive
Officer--18 months; Chief Operating Officer and Chief Financial Officer--12
months; Vice President, Worldwide Sales--12 months; certain other Vice
Presidents--six months; and other Executives--three months. 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 the
Company.
 
EMPLOYEE BENEFIT PLANS
 
  1997 EQUITY INCENTIVE PLAN. In January 1997, the Board adopted the 1997
Plan. In October 1997, the Board increased the number of Shares of Common
Stock for issuance under the 1997 Plan to a total of 2,200,000. The
Stockholders approved the 1997 Plan and the share increase in October 1997.
The 1997 Plan became effective in January 1997 and serves as the successor to
the 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. Shares
that (i) are issuable upon exercise of an option granted pursuant to the 1997
Plan but cease to be subject to such option for any reason other than exercise
of such option, (ii) are subject to an award granted under the 1997 Plan but
are forfeited or are repurchased by the Company at the original issue price or
(iii) are subject to an award granted pursuant to the 1997 Plan that otherwise
terminates without shares being issued, will again be available for grant and
issuance
 
                                      57
<PAGE>
 
in connection with future awards under the 1997 Plan. On the effective date of
the initial public offering, the 1997 Plan will terminate. Options granted
under the 1997 Plan before its termination continue to remain outstanding in
accordance with their options.
 
  The 1997 Plan provides for the grant of stock options and the issuance of
restricted stock by the Company to its employees, officers, directors,
consultants, independent contractors and advisers. The 1997 Plan permits the
grant of options that are either incentive stock options (as defined in
Section 422 of the Code) or nonqualified stock options, on terms (including
the exercise price, which may not be less than 85% of the fair market value of
the Company's Common Stock, and the vesting schedule) determined by the Board,
subject to certain statutory and other limitations in the 1997 Plan. In
addition to, or in tandem with, other awards under the 1997 Plan, the Board
may grant participants restricted stock awards to purchase the Company's
Common Stock for not less than 85% of its fair market value at the time of
grant. The other terms of such restricted stock awards may be determined by
the Board. Such stock bonuses may be awarded for the satisfaction of
performance goals established in advance. The 1997 Plan will terminate ten
years from the Effective Date, unless terminated earlier in accordance with
the provisions of the 1997 Plan.
 
  1998 EQUITY INCENTIVE PLAN. In January 1998, the Board adopted, subject to
stockholder approval, the 1998 Equity Incentive Plan (the "1998 Plan") to
provide for the grant of stock options, restricted stock and stock bonuses to
employees, officers, directors, consultants, independent contractors and
advisors of the Company or any parent or subsidiary of the Company. On the
effective date of this offering, the 1998 Plan will become effective as the
successor to the 1997 Plan. Although the 1997 Plan will terminate on the
effective date of this offering, options granted thereunder prior to the
effective date of this offering will remain outstanding according to their
terms. The total number of shares reserved and available for grant and
issuance pursuant to the 1998 Plan is 1,500,000 plus shares that pour over
from the 1997 Plan. The shares that pour over from the 1997 Plan are shares
that (a) remain available for grant under the 1997 Plan on the effective date
of the 1998 Plan, (b) are subject to issuance upon exercise of an option
granted under the 1997 Plan that cease to be subject to such option for any
reason other than exercise of such option and (c) are issued under awards
granted under the 1997 Plan, but are repurchased by the Company at the price
at which the shares were originally issued. Shares that are subject to (x)
issuance upon exercise of an option granted under the 1998 Plan that cease to
be subject to such option for any reason other than exercise, (y) awards
granted under the 1998 Plan that are forfeited or are repurchased by the
Company at the original issue price and (z) awards that otherwise terminate
without shares being issued will again be available for grant and issuance in
connection with future awards under the 1998 Plan.
 
  The 1998 Plan will terminate in January 2008, unless earlier terminated by
the Board. No person will be eligible to receive more than 750,000 shares in
any calendar year pursuant to equity awards under the 1998 Plan, other than a
new employee of the Company who will be eligible to receive no more than
1,250,000 shares in the calendar year in which such employee commences
employment. The 1998 Plan will be administered by the Compensation Committee
of the Board. The Compensation Committee has the authority to construe and
interpret the 1998 Plan and any agreement made thereunder, grant equity awards
and make all other determinations necessary or advisable for the
administration of the 1998 Plan. The 1998 Plan permits the grant of incentive
stock options ("ISOs") that qualify under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), and nonqualified stock options
("NQSOs"). ISOs may be granted only to employees of the Company or of any
parent or subsidiary of the Company. NQSOs, stock bonuses and restricted stock
may be granted to all individuals eligible to receive grants under the 1998
Plan. The exercise price of ISOs must be at least equal to the fair market
value of the Company's Common Stock on the date of grant. The exercise price
of NQSOs must be at least equal to 85% of the fair market value of the
Company's Common Stock on the date of grant. The purchase price of restricted
stock will be determined by the
 
                                      58

Compensation Committee. The maximum term of an option is ten years. Options
typically vest over a four-year period. Vesting will stop if the optionee
ceases to provide services to the Company or any parent or subsidiary of the
Company, but options will generally remain exercisable for a period of three
months following the termination of services. If the optionee's termination is
for cause, his or her options will generally terminate immediately. If the
optionee's termination is due to death or disability, the optionee or his or
her estate will generally have twelve months in which to exercise. In the
event of certain changes in control transactions, outstanding equity awards
may be assumed or substituted by the successor corporation, if the successor
corporation does not assume or substitute the awards, the awards will
terminate prior to the effectiveness of the transaction.
 
  1998 EMPLOYEE STOCK PURCHASE PLAN. In January 1998, the Board adopted,
subject to stockholder approval, the 1998 Employee Stock Purchase Plan (the
"1998 Purchase Plan") and reserved a total of 600,000 shares of the Company's
Common Stock for issuance thereunder. The Purchase Plan will become effective
on the first business day on which price quotations for the Company's Common
Stock are available on the Nasdaq National Market. The Purchase Plan permits
eligible employees to acquire shares of the Company's Common Stock through
payroll deductions. The Purchase Plan is intended to qualify as an "employee
stock purchase plan" under Section 423 of the Code. Except for the initial
offering, each offering under the Purchase Plan will be for a period of 24
months (the "Offering Period") commencing on May 1 and November 1 of each year
and ending on October 31 and April 30 of each year. The first Offering Period
will begin on the date on which price quotations for the Company's Common
Stock are first available on the Nasdaq National Market and will end on April
30, 2000, unless otherwise determined by the Board. Except for the first
Offering Period, each Offering Period will consist of four purchase periods,
each six months in length ("Purchase Period"). The Board has the power to
change the duration of Offering Periods or Purchase Periods without
stockholder approval, provided that the change is announced at least 15 days
prior to the scheduled beginning of the first Offering Period or Purchase
Period to be affected. Eligible employees may select a rate of payroll
deduction between 2% and 10% of their base compensation, subject to certain
limits set forth in the Purchase Plan. The purchase price for the Company's
Common Stock purchased under the Purchase Plan is 85% of the lesser of the
fair market value of the Company's Common Stock on the first day of the
applicable Offering Period or on the last day of the respective Purchase
Period.
 
  401(K) PLAN. The Company sponsors the Exodus Communications, Inc. 401(k)
Plan (the "401(k) Plan"). Employees who complete three months of service with
the Company are eligible to participate ("Participants"). Participants may
contribute up to 20% of their current compensation, up to a statutorily
prescribed annual limit, to the 401(k) Plan. Each Participant is fully vested
in his or her salary reduction contributions. Participant contributions are
held in trust as required by law. Individual Participants may direct the
trustee to invest their accounts in authorized investment alternatives. The
Company may make discretionary matching contributions to the 401(k) Plan in an
amount equal to a percentage the Company from time to time may deem advisable
of the Participant's salary reduction contributions. Salary reduction
contributions in excess of 6% of the Participant's compensation are
disregarded for purposes of the match. The Company may also make fully vested
qualified non-elective contributions on behalf of employees who are not
"highly compensated." In addition, the Company may make discretionary
contributions, although it has not done so to date. Discretionary and matching
contributions are subject to a vesting schedule. The 401(k) Plan is intended
to qualify under Section 401(a) of the Internal Revenue Code so that
contributions to the 401(k) Plan, and income earned on such contributions, are
not taxable to Participants until withdrawn or distributed from the 401(k)
Plan.

  Since January 1, 1995, there has not been, nor is there currently proposed,
any transaction or series of similar transactions to which the Company was or

director, executive officer or holder of more than 5% of the Common Stock of
the Company had or will have a direct or indirect interest other than (i)

                         DESCRIPTION OF CAPITAL STOCK
 
  Immediately following the closing of this offering, the authorized capital
stock of the Company will consist of 50,000,000 shares of Common Stock, $0.001
par value per share, and 5,000,000 shares of Preferred Stock, $0.001 par value
per share. As of December 31, 1997, and assuming the conversion of all
outstanding Preferred Stock into Common Stock immediately prior to the closing
of this offering, there were outstanding 13,439,624 shares of Common Stock
held of record by 117 stockholders, warrants to purchase 950,163 shares of
Common Stock and options to purchase 1,709,286 shares of Common Stock.
 
COMMON STOCK
 
  Subject to preferences that may apply to shares of Preferred Stock
outstanding at the time, the holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the Board may from time to time determine. Each
stockholder is entitled to one vote for each share of Common Stock held on all
matters submitted to a vote of stockholders. Cumulative voting for the
election of directors is not provided for in the Company's Certificate of
Incorporation, which means that the holders of a majority of the shares voted
can elect all of the directors then standing for election. The Common Stock is
not entitled to preemptive rights and is not subject to conversion or
redemption. Upon a liquidation, dissolution or winding-up of the Company, the
assets legally available for distribution to stockholders are distributable
ratably among the holders of the Common Stock and any participating Preferred
Stock outstanding at that time after payment of liquidation preferences, if
any, on any outstanding Preferred Stock and payment of other claims of
creditors. Each outstanding share of Common Stock is, and all shares of Common
Stock to be outstanding upon completion of this offering will be, fully paid
and nonassessable.
 
PREFERRED STOCK
 
  Upon the closing of this offering, all outstanding shares of Preferred Stock
(the "Convertible Preferred") will be converted into shares of Common Stock.
See Note 5 of Notes to Financial Statements for a description of the
Convertible Preferred. The Board is authorized, subject to limitations
prescribed by Delaware law, to provide for the issuance of additional shares
of Preferred Stock in one or more series, to establish from time to time the
number of shares to be included in each such series, to fix the powers,
designations, preferences and rights of the shares of each wholly unissued
series and designate any qualifications, limitations or restrictions thereon
and to increase or decrease the number of shares of any such series (but not
below the number of shares of such series then outstanding) without any
further vote or action by the stockholders. The issuance of Preferred Stock
with voting or conversion rights could adversely affect the voting power or
other rights of the holders of Common Stock and may have the effect of
delaying, deferring or preventing a change in control of the Company. The
Company has no current plan to issue any shares of Preferred Stock.
 
WARRANTS
 
  As of December 31, 1997, the Company had outstanding warrants to purchase
950,163 shares of Common Stock at a weighted average per share exercise price
of $4.29 (of which warrants to purchase at least 615,454 shares of Common
Stock are expected to be exercised on or before the closing of the offering).
The warrants that remain outstanding after the offering will expire between
December 2000 and September 2004.
 
ANTI-TAKEOVER PROVISIONS
 
 DELAWARE LAW
 
  Section 203 ("Section 203") of the Delaware General Corporation Law is
applicable to corporate takeovers of Delaware corporations. Subject to certain
exceptions set forth therein, Section 203
 
                                      65
<PAGE>
 
provides that a corporation shall not engage in any business combination with
any "interested stockholder" for a three-year period following the date that
such stockholder becomes an interested stockholder unless (a) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder, (b) upon consummation of the transaction that resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding certain shares)
or (c) on or subsequent to such date, the business combination is approved by
the board of directors of the corporation and by the affirmative votes of at
least two-thirds of the outstanding voting stock that is not owned by the
interested stockholder. Except as specified in Section 203, an interested
stockholder is generally defined to include any person that is the owner of
15% or more of the outstanding voting stock of the corporation, or is an
affiliate or associate of the corporation and was the owner of 15% or more of
the outstanding voting stock of the corporation, or is an affiliate or
associate of the corporation and was the owner of 15% or more of the
outstanding voting stock of the corporation any time within three years
immediately prior to the relevant date, and the affiliates and associates of
such person. Under certain circumstances, Section 203 makes it more difficult
for an interested stockholder to effect various business combinations with a
corporation for a three-year period, although the stockholders may, by
adopting an amendment to the corporation's certificate of incorporation or
bylaws, elect not to be governed by this section, effective 12 months after
adoption. The Company's certificate of incorporation and the bylaws do not
exclude the Company from the restrictions imposed under Section 203. It is
anticipated that the provisions of Section 203 may encourage companies
interested in acquiring the Company to negotiate in advance with the Board
since the stockholder approval requirement would be avoided if a majority of
the directors then in office approve either the business combination or the
transaction that resulted in the stockholder becoming an interested
stockholder. These provisions may have the effect of deterring hostile
takeovers or delaying changes in control of the Company, which could depress
the market price of the Common Stock and which could deprive the stockholders
of opportunities to realize a premium on shares of the Common Stock held by
them.
 
 CHARTER AND BYLAW PROVISIONS
 
  The Company's Certificate of Incorporation and Bylaws contain certain
provisions that could discourage potential takeover attempts and make more
difficult attempts by stockholders to change management. The Company's
Certificate of Incorporation provides that stockholders may not take action by
written consent but only at a stockholders' meeting, and that special meetings
of the stockholders of the Company may only be called by the Chairman of the
Board or a majority of the Board.
 
REGISTRATION RIGHTS
 
  Beginning six months after the date of this offering (assuming no exercise
of the Underwriters' over-allotment option), the holders of 13,234,880 shares
of Common Stock and the holders of warrants to purchase 950,163 shares of
Common Stock (collectively, the "Registrable Securities") will have certain
rights with respect to the registration of those shares under the Securities
Act. If requested by at least 30% of the Registrable Securities (or at least
25% of the Registrable Securities issued upon conversion of the Series C
Preferred Stock of the Company) the Company must file a registration statement
to register such securities so long as the aggregate offering price, net of
any underwriting discounts and commissions, is at least $7.5 million. In
addition, if the Company proposes to register any of its shares of Common
Stock under the Securities Act other than in connection with a Company
employee benefit plan or certain corporate acquisitions, mergers or
reorganizations, the holders of the Registrable Securities may require the
Company to include all or a portion of their shares in such registration,
subject to certain rights of the managing underwriter to limit the number of
shares in any such offering.
 
                                      66
<PAGE>
 
  Further, holders of Registrable Securities holding at least 20% of the
Registrable Securities (or at least 15% of the Registrable Securities issued
upon conversion of the Series C Preferred Stock of the Company) may require
the Company to register all or any portion of their Registrable Securities on
Form S-3 when such form becomes available to the Company, subject to certain
conditions and limitations. The Company may be required to effect up to two
such registrations per year.
 
  All expenses incurred in connection with such registrations (other than
underwriters' discounts and commissions) will be borne by the Company, except
that the holders of the Registrable Securities will bear the expenses of any
Form S-3 registrations after the first such registration. The registration
rights expire seven years after the closing of this offering. In addition, no
holder of Registrable Securities will be entitled to registration rights if
and so long as such holder can sell all of its Registrable Securities in
compliance with Rule 144 of the Securities Act during any 90-day period.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Company's Common Stock is Boston
EquiServe Limited Partnership.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock of the
Company, and there can be no assurance that a significant public market for
the Common Stock will develop or be sustained after this offering. Future
sales of substantial amounts of Common Stock (including shares issued upon
exercise of outstanding options and warrants) in the public market after this
offering could adversely affect market prices prevailing from time to time and
could impair the Company's ability to raise capital through sale of its equity
securities. As described below, no shares currently outstanding will be
available for sale immediately after this offering due to certain contractual
restrictions on resale. Sales of substantial amounts of Common Stock of the
Company in the public market after the restrictions lapse could adversely
affect the prevailing market price and the ability of the Company to raise
equity capital in the future.
 
  Upon completion of this offering, the Company will have outstanding
shares of Common Stock, assuming no exercise of the Underwriters' over-
allotment option and no exercise of outstanding options or warrants that do
not expire upon the closing. Of these shares, the     shares sold in this
offering will be freely tradable without restriction under the Securities Act
unless purchased by "affiliates" of the Company as that term is defined in
Rule 144 under the Securities Act. The remaining 13,439,624 shares held by
existing stockholders (the "Restricted Shares") are subject to lock-up
agreements providing that, with certain limited exceptions, the stockholder
will not offer, sell, contract to sell, grant an option to purchase, make a
short sale or otherwise dispose of or engage in any hedging or other
transaction that is designed or reasonably expected to lead to a disposition
of any shares of Common Stock or any option or warrant to purchase shares of
Common Stock or any securities exchangeable for or convertible into shares of
Common Stock for a period of 180 days after the date of this Prospectus
without the prior written consent of the representatives of the Underwriters.
As a result of these lock-up agreements, notwithstanding possible earlier
eligibility for sale under the provisions of Rules 144, 144(k) and 701, none
of these shares will be salable until 181 days after the date of this
Prospectus. Beginning 181 days after the date of this Prospectus, 12,086,491
Restricted Shares will be eligible for sale in the public market, although all
but 3,526,872 shares will be subject to certain volume limitations.
Thereafter, 1,014,367 Restricted Shares will become eligible for sale between
the end of the lock-up period and December 31, 1998 and the remaining 338,766
Restricted Shares will become eligible for sale starting in 1999. In addition,
as of December 31, 1997, there were outstanding 1,709,286 options and 950,163
warrants to purchase Common Stock (of which warrants for 615,454 shares are
expected to be exercised on or before the closing of this offering).
 
                                      67
<PAGE>
 
All of such options and warrants will be subject to lock-up agreements.
Goldman, Sachs & Co. may, in its sole discretion and at any time without
notice, release all or any portion of the securities subject to lock-up
agreements.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an affiliate) would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of: (i) 1% of the number of shares of Common Stock then
outstanding (which will equal approximately     shares immediately after this
offering); or (ii) the average weekly trading volume of the Common Stock
during the four calendar weeks preceding the filing of a Form 144 with respect
to such sale. Sales under Rule 144 are also subject to certain manner of sale
provisions and notice requirements and to the availability of current public
information about the Company. Under Rule 144(k), a person who is not deemed
to have been an affiliate of the Company at any time during the three months
preceding a sale, and who has beneficially owned the shares proposed to be
sold for at least two years (including the holding period of any prior owner
except an affiliate), is entitled to sell such shares without complying with
the manner of sale, public information, volume limitation or notice provisions
of Rule 144.
 
  Rule 701 permits resales of shares in reliance upon Rule 144 but without
compliance with certain restrictions, including the holding period
requirement, of Rule 144. Any employee, officer or director of or consultant
to the Company who purchased his or her shares pursuant to a written
compensatory plan or contract may be entitled to rely on the resale provisions
of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under
Rule 144 without complying with the holding period requirements of Rule 144.
Rule 701 further provides that non-affiliates may sell such shares in reliance
on Rule 144 without having to comply with the holding period, public
information, volume limitation or notice provisions of Rule 144. All holders
of Rule 701 shares are required to wait until 90 days after the date of this
Prospectus before selling such shares. However, all shares issued pursuant to
Rule 701 are subject to lock-up agreements and will only become eligible for
sale at the earlier of the expiration of the 180-day lock-up agreements or no
sooner than 90 days after the offering upon obtaining the prior written
consent of the representatives of the Underwriters.
 
  Immediately after this offering, the Company intends to file a registration
statement under the Securities Act covering shares of Common Stock subject to
outstanding options under the 1995 Plan and the 1997 Plan and reserved for
issuance under the 1998 Plan, the Directors Plan and the Purchase Plan. Based
on the number of shares subject to outstanding options at December 31, 1997
and currently reserved for issuance under all such plans, such registration
statement would cover approximately 4,659,215 shares. Such registration
statement will automatically become effective upon filing. Accordingly, shares
registered under such registration statement will, subject to Rule 144 volume
limitations applicable to affiliates of the Company, be available for sale in
the open market immediately after the 180-day lock-up agreements expire. Also
beginning six months after the date of this offering, holders of 13,234,880
Restricted Shares and warrants to purchase 950,163 shares of Common Stock of
the Company will be entitled to certain rights with respect to registration of
such shares for sale in the public market. See "Description of Capital Stock--
Registration Rights."

  The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Fenwick & West LLP, Palo Alto,
California. Certain legal matters in connection with this offering will be
passed upon for the Underwriters by Wilson Sonsini Goodrich & Rosati,

         FORM OF REPORT OF KPMG PEAT MARWICK LLP, INDEPENDENT AUDITORS
 
  When the reincorporation of the Company in Delaware, as described in Note 8
of the Notes to Financial Statements, has been consummated, we will be in a
position to render the following report.
 
                                                          KPMG PEAT MARWICK LLP
 
The Board of Directors and Stockholders 
Exodus Communications, Inc.:
 
  We have audited the accompanying balance sheets of Exodus Communications,
Inc. as of December 31, 1995 and 1996, and September 30, 1997, and the related
statements of operations, stockholders' (deficit) equity, and cash flows for
each of the years in the two-year period ended December 31, 1996, and for the
nine months ended September 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our 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 financial statements referred to above present fairly,
in all material respects, the financial position of Exodus Communications,
Inc. as of December 31, 1995 and 1996, and September 30, 1997, and the results
of its operations and its cash flows for each of the years in the two-year
period ended December 31, 1996, and for the nine months ended September 30,
1997, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
 THE COMPANY
 
  Exodus Communications, Inc. is the successor to a Maryland corporation that
was formed in August 1992 and reincorporated in California in May 1995. Unless
the context otherwise requires, the term "Company" or "Exodus" refers to
Exodus Communications, Inc. and its Maryland predecessor. Exodus is a leading
provider of Internet system and network management solutions for enterprises
with mission-critical Internet operations.
 
 INITIAL PUBLIC OFFERING AND UNAUDITED PRO FORMA BALANCE SHEET
 
  In January 1998, the Board of Directors authorized the filing of a
registration statement with the Securities and Exchange Commission ("SEC")
that would permit the Company and certain stockholders of the Company to sell
shares of the Company's common stock in connection with a proposed initial
public offering ("IPO"). If the offering is consummated under the terms
presently anticipated, all the then outstanding shares of the Company's
redeemable convertible preferred stock will automatically convert into shares
of common stock on a one-for-three basis upon the closing of the proposed IPO.
The sale by the Company of 2,631,579 shares of preferred stock at $2.85 per
share on December 15, 1997 and the conversion of the redeemable convertible
preferred stock have been reflected in the accompanying unaudited pro forma
balance sheet as if they had occurred on September 30, 1997.
 
 USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 REVENUE RECOGNITION
 
  Service revenues consist of monthly fees for server hosting, Internet
connectivity, collaborative management and Internet technology services and
one-time fees for installation. Service revenues (other than installation
fees) are generally billed and recognized ratably over the term of the
contract, generally one year. Installation fees are typically recognized at
the time that installation occurs. Equipment revenues consist of payments from
customers for third-party equipment sold by the Company. Revenues from
equipment sales are recognized at the time the equipment is shipped to the
customer or placed into service at the an Internet Data Center.
 
 FINANCIAL INSTRUMENTS AND CONCENTRATION OF CREDIT RISK
 
  The carrying value of the Company's financial instruments, including cash
and cash equivalents and accounts receivable, approximates fair market value.
Financial instruments that potentially expose the Company to a concentration
of credit risk principally consist of cash and cash equivalents and accounts
receivable.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
 
  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 credit losses. To date, such
losses have not been significant. The balance of the allowance for bad debts
was $22,000, $15,000 and $141,000 as of December 31, 1995 and 1996, and
September 30, 1997, respectively. In 1995, revenues from a single customer
comprised 24% of total revenues.
 
 CASH AND CASH EQUIVALENTS
 
  Cash equivalents consist of highly liquid investments with original
maturities of 90 days or less.
 
 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
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 management services that are included
in the Company's co-location service in accordance with Statement of Financial
Accounting Standards ("SFAS") No. 86, Accounting for the Costs of Computer
Software to be Sold, Leased, or Otherwise Marketed. Costs are capitalized
after technological feasibility is achieved; generally upon the development of
a working model. To date, software development costs capitalizable under SFAS
No. 86 have not been material.
 
 INCOME TAXES
 
  The Company uses the asset and liability method of accounting for income
taxes. Under this method, deferred tax assets and liabilities are determined
based on the difference between the financial statement and tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the differences are expected to affect taxable income. Valuation allowances
are established when necessary to reduce deferred tax assets to the amounts
expected to be recovered.
 
 STOCK-BASED COMPENSATION
 
  The Company uses the intrinsic value-based method to account for all of its
employee stock-based compensation plans.
 
 IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF
 
  The Company evaluates its long-lived assets and certain identifiable
intangibles for impairment whenever events or changes in circumstances
indicate that the carrying amount of such assets or intangibles may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair
value less costs to sell.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
 
 UNAUDITED INTERIM FINANCIAL STATEMENTS
 
  The accompanying unaudited interim financial statements for the nine months
ended September 30, 1996 have been prepared on substantially the same basis as
the audited financial statements and include all adjustments, consisting only
of normal recurring adjustments, necessary for a fair presentation of the
financial information set forth therein.
 
 PRO FORMA PER SHARE INFORMATION
 
  Pro forma per share information is computed using net loss and is based on
the weighted-average number of outstanding shares of common stock and
redeemable convertible preferred stock on an "as if converted" basis, and,
when dilutive, common stock equivalent shares from stock options and warrants
outstanding, using the treasury stock method.
 
  Pursuant to certain SEC staff accounting bulletins, common stock,
convertible preferred stock issued for consideration below the assumed IPO
price, and stock options granted and warrants issued with exercise prices
below the assumed IPO price during the 12-month period prior to the date of
the initial filing of the registration statement for the IPO, even when
antidilutive, have been included in the calculation of pro forma net loss per
common share, using the treasury stock method based on the assumed IPO price,
as if they were outstanding for all periods presented. Due to the significant
impact of the conversion of preferred shares into common shares at the closing
of the IPO, historical net loss per common share is not meaningful and
therefore is not presented.
 
 RECENT ACCOUNTING PRONOUNCEMENTS
 
  The Financial Accounting Standards Board ("FASB") recently issued SFAS No.
128, Earnings Per Share. SFAS No. 128 requires the presentation of basic
earnings per share ("EPS") and, for companies with complex capital structures,
diluted EPS. SFAS No. 128 is effective for annual and interim periods ending
after December 15, 1997. The Company expects that, for profitable periods,
basic EPS will be higher than EPS as presented in the accompanying financial
statements and diluted EPS will not differ materially from EPS as presented in
the accompanying financial statements. Computations for loss periods should
not change significantly.
 
  The FASB also recently issued SFAS No. 130, "Reporting Comprehensive
Income." SFAS No. 130 establishes standards for reporting and displaying
comprehensive income and its components in financial statements. It does not,
however, require a specific format, but requires the Company to display an
amount representing total comprehensive income for the period in its financial
statements. The Company is in the process of determining its preferred format.
SFAS No. 130 is effective for fiscal years beginning after December 15, 1997.
 
  The FASB also recently issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for
the way public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises to
report selected information about operating segments in interim financial
reports. SFAS No. 131 is effective for financial statements for periods
beginning after December 31, 1997. The Company has determined that it does not
have any separately reportable business segments.

  The rights, preferences, privileges and restrictions of the redeemable
convertible preferred stock are as follows:
 
  . Shares of Series A, A1, B, B1, C and C1 preferred stock are convertible
    at the option of the holder into an equal number of shares of common
    stock subject to certain price-based antidilution adjustments for the
    Series A, B and C redeemable convertible preferred stock.
 
  . Conversion is automatic upon either (i) the closing of a public offering
    of the Company's common stock at an offering price of not less than
    $15.00 per share and aggregate proceeds of at least $30,000,000 (a
    "Qualified IPO") or (ii) the election of the majority of the stockholders
    of Series A, A1, B, B1, C and C1 redeemable convertible preferred stock
    voting as a single class.
 
  . The holders of Series A, A1, B and B1 redeemable convertible preferred
    stock are entitled to noncumulative dividends at annual rates of $0.04,
    $0.04, $0.084 and $0.084 per share, respectively, when and if declared by
    the Board of Directors. The holders of Series C and C1 redeemable
    convertible preferred stock are entitled to cumulative dividends at the

    stock have liquidation preferences of $0.4129, $0.4129, $0.84, $0.84,
    $1.362 and $1.362 per share, respectively, plus all declared but unpaid
    dividends.

    preferred stock of the full preferential amounts, holders of common stock
    will receive all remaining assets pro rata based on the number of shares
    of common stock held.

    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 IS UNAUDITED)
 
 
  . At any time after June 25, 2002, upon notification by not less than a
    majority of the holders of Series A, A1, B and B1 redeemable convertible
    preferred stock, the Company must redeem up to 50% of the outstanding
    shares by paying in cash a sum per share equal to the original issue
    price (as adjusted for any stock dividends, combinations or splits with
    respect to such shares) plus all declared but unpaid dividends. The
    remaining shares of Series A, A1, B and B1 redeemable convertible
    preferred stock can be redeemed by the stockholders at any time after
    June 25, 2003. At the option of the holders of the Series C redeemable
    convertible preferred stock, the Series C redeemable convertible
    preferred stock must be redeemed in one-half increments in June 2002 and
    June 2003 at a redemption price equal to the greater of $1.362 per share
    plus cumulative dividends or the fair market value. As of September 30,
    1997, the Company had accreted $448,000 towards the fair market value of
    the Series C redeemable convertible preferred stock.
 
  . Each share of Series A, A1, B, B1, C and C1 redeemable convertible
    preferred stock has voting rights on an "as if converted" basis.
 
  . In the event the Company proposes to issue additional shares of any
    series of preferred stock, the current holders of such shares will have
    the right of first refusal to participate on a pro rata basis. In the
    event of a dilutive subsequent financing, the holders of Series A, B and
    C redeemable convertible preferred stock are provided with antidilution
    protection if they purchase their pro rata share of such dilutive
    financing. If they do not purchase their pro rata share, their Series A,
    B and C redeemable convertible preferred stock will convert to Series A1,
    B1 and C1 redeemable convertible preferred stock, respectively, which
    will have no such antidilution protection.

 STOCK PURCHASE PLAN
 
  During 1995, the Company adopted a Stock Purchase Plan under which 366,667
shares of common stock are authorized. Awards totaling 96,334 and 11,034
shares of common stock were granted to individuals in 1995 and 1996,
respectively, at an exercise 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 nine months ended September 30, 1997. Generally, the shares are
subject to a 50-month vesting period. As of September 30, 1997, 36,334 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, 41,734 had been repurchased by the Company as of September
30, 1997.

 STOCK OPTIONS
 
  In January 1997, the Company adopted the 1997 Equity Incentive Plan (the
"1997 Plan"), which serves 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. The Company has reserved for issuance under the 1997 Plan to
employees and consultants 2,200,000 shares of the Company's common stock which
may 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.
 
  The Company uses the intrinsic value method in accounting for its 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 options granted in April, June and July 1997. With respect
to the options granted in April, June and July 1997, the Company has recorded
deferred stock compensation of $724,000 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 in accordance with FASB
Interpretation No. 28 over the vesting period of the individual options,
generally four years. Had compensation cost been determined in accordance with
SFAS No. 123, the Company's 1995 and 1996 net loss would not have been
significantly affected. For the nine months ended September 30, 1997, the
related pro forma net loss would have been $14,750,000 and pro forma net loss
per share would have been $1.00.
 
  The fair value of each option is estimated on the date of grant using the
Black-Scholes method with the following weighted average assumptions:

  In March and June 1997, in connection with the bridge financing convertible
promissory notes discussed above, the Company issued warrants to purchase
198,697 shares of the Company's Series B redeemable convertible preferred
stock at $0.84 per share. The warrants expire in 2002 or upon the closing of
an IPO. In April 1997, in connection with the $3,000,000 equipment line of
credit (see Note 3), the Company issued warrants to purchase 196,429 shares of
the Company's Series B1 redeemable convertible preferred stock at $0.84 per
share. These warrants expire in April 2007. In June 1997, in connection with
the issuance of the Company's Series C redeemable convertible preferred stock,
the Company issued warrants to purchase 1,579,011 shares of the Company's
Series C redeemable convertible preferred stock at $1.362 per share. These
warrants expire the earlier of June 2002 or immediately prior to the closing
of a Qualified IPO. In August and September 1997, in connection with the
$3,000,000 equipment line of credit and the $6,500,000 equipment line of

271,598 shares of the Company's Series C1 redeemable convertible preferred
stock at $1.362 per share. These warrants expire through September 2004.
 
  The fair value of all warrant issuances, calculated using the Black-Scholes
option pricing module, using the following assumptions: dividends--none;
expected life--contractual term; risk free interest rates--5.8% to 6.7%;
volatility--60%, was not material except for the 1,579,011 warrants issued in
connection with the sale of the Series C redeemable convertible preferred
stock. The value of these warrants was determined to be $1,200,000 which was
recorded as a credit to additional paid-in capital as of September 30, 1997.
 
(6) COMMITMENTS AND CONTINGENCIES
 
 Leases
 
  The Company has entered into a number of operating leases for its
facilities. The leases expire from 1997 through 2007. The Company has
collateralized letters of credit with certificates of deposit aggregating
$1,053,000 for these leases. The Company also leases certain data center
infrastructure and equipment under capital leases (see Note 5). Certain of
these capital leases were entered into as sales-leaseback transactions. No

  The Company's rent expense was $85,000, $248,000, and $1,099,000 for the
years ended December 31, 1995 and 1996 and for the nine months ended September
30, 1997, respectively.
 
 Telecommunications Agreement
 
  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.
 
 Royalty Agreement
 
  In April 1997, the Company entered into an agreement with a software company
under which the Company licensed certain software for a royalty based on 1% of
the Company's gross revenues. Royalty expenses related to this agreement were
not significant for the nine months ended September 30, 1997.
 
 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.
 
(7) INCOME TAXES
 
  As of September 30, 1997, the Company had federal and California net
operating loss carryforwards of approximately $19,600,000 and $9,800,000,
respectively, which can be used to offset the Company's future tax
liabilities. The federal and California net operating loss carryforwards will
begin expiring in 2011 and 2001, 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 that constitutes an "ownership change" as defined by
Section 382 of the Internal Revenue Code. As stated in Note 5, the Company has
had numerous equity transactions. These transactions most likely have
subjected its net operating loss to the aforementioned restrictions. The
Company plans to compute exact limitations upon realization of taxable
earnings and associated utilization of the net operating loss carryforwards.
 
  The Company has deferred tax assets as of December 31, 1996 and September
30, 1997 of approximately $2,000,000 and $7,600,000, respectively, which have
been fully offset by valuation allowances. The deferred tax assets principally
resulted from the net operating loss carryforwards. The Company has provided a
valuation allowance due to the uncertainty of generating future profits that
would allow for the realization of such deferred tax assets. Accordingly, no
tax benefit was recorded in the accompanying statements of operations.
 
(8) SUBSEQUENT EVENTS
 
 Reincorporation and Reverse Stock Split
 
  In December 1997, the Board of Directors approved the Company's
reincorporation in the state of Delaware, which will become effective prior to
the effectiveness of the proposed IPO. The Certificate of Incorporation of the
Delaware successor corporation authorizes 50,000,000 shares of common stock,
$0.001 par value per share, and 5,000,000 shares of preferred stock, $0.001
par value per

share. The Board of Directors also approved a one-for-three reverse stock
split of the Company's common stock. The accompanying financial statements
have been retroactively restated to give effect to the reincorporation and
reverse stock split.
 
 Stock Option Grants
 
  In October, November and December 1997, the Company granted options to
purchase 638,334, 50,334 and 38,334 shares, respectively, of the Company's
common stock at exercise prices from $0.75 to $5.25 per share. In conjunction
with such grants, the Company recorded deferred stock compensation of
$2,758,000 for the difference at the grant date between the exercise price and
the fair value of the common stock underlying the options.
 
 Redeemable Convertible Preferred Stock and Stockholders' (Deficit) Equity
 
  In December 1997, the Company amended its Articles of Incorporation to
increase the number of authorized shares of common stock to 53,281,579 and
authorize 3,231,579 shares each of Series D and D1 redeemable convertible
preferred stock. The amended Articles of Incorporation also reduced the
offering price for a Qualified IPO, as defined, for all classes of redeemable
convertible preferred stock from $15.00 to $9.75, if the Qualified IPO occurs
prior to April 30, 1998.
 
  In December 1997, the Company issued 2,631,579 shares of Series D redeemable
convertible preferred stock at $2.85 per share for cash proceeds aggregating
of $7,500,000.
 
  The rights, preferences, privileges and restrictions of the Series D and D1
redeemable convertible preferred stock are the same as the for the Series C
and C1 redeemable convertible preferred stock, respectively, except for the
following:
 
  . The holders of Series D and D1 redeemable convertible preferred stock are
    entitled to cumulative dividends at the annual rate of $0.20 per share.
 
  . Shares of Series D and D1 redeemable convertible preferred stock have a
    liquidation preference of $2.85 per share, plus all declared but unpaid
    dividends.
 
  . At the option of the holders, the Series D redeemable convertible
    preferred stock will be redeemable in one-half increments in June 2002
    and June 2003 at a redemption price equal to the greater of $2.85 per
    share plus cumulative dividends or the fair market value.
 
  . In the event the Company proposes to issue additional shares of any
    series of preferred stock, the current holders of Series D redeemable
    convertible preferred stock will have the right of first refusal to
    participate on a pro rata basis. In the event of a dilutive subsequent
    financing, the holders of Series D redeemable convertible preferred stock
    are provided with antidilution protection if they purchase their pro rata
    share of such dilutive financing. If they do not purchase their pro rata
    share, their Series D redeemable convertible preferred stock converts to
    Series D1 redeemable convertible preferred stock, which receives no such
    antidilutive protection.
 
 Directors Option Plan
 
  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 becomes a
member of the Board of Directors 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.
 
 Employee Stock Purchase Plan
 
  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 at the
beginning or end of each offering period.
 
 1998 Equity Incentive Plan
 
  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 will
become 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 10 years and generally will vest over
four years. The 1998 Plan will terminate in January 2008.
 
 Bank Borrowings, Debt and Lease Financing
 
  In October, November and December 1997, the Company drew down the remaining
$4,600,000 under its $6,500,000 equipment line of credit facility.
 
  In December 1997, the Company entered into an agreement for an $8,000,000
line of credit facility, bearing interest at 12.95% and expiring in January
1999. In conjunction with this agreement, the Company issued warrants to
purchase 247,826 shares of the Company's Series D1 redeemable convertible
preferred stock at a price of $2.85 per share, which expire in December 2007.
The fair value of the warrants, calculated using the Black-Scholes option
pricing model, using the assumptions described in Note 5, is approximately
$530,000. This amount will be amortized on a straight line basis through
January 1999.
 
  In November and December 1997, the Company drew down the remaining $444,000
available under its April 1997 $3,000,000 equipment line of credit facility.
 
  In December 1997, the Company's $1,000,000 bank line of credit agreement was
amended to increase the available line to $5,000,000. The Company then drew
down $3,000,000 on this bank line of credit, which was repaid on January 2,
1998. The line of credit expires in December 1998.
 
  In December 1997, the Company entered into an agreement for a 42-month
$4,000,000 equipment lease facility for equipment delivered no later than
March 31, 1998.
 
  In December 1997, the Company entered into an agreement for a 42-month
$5,000,000 equipment line of credit, bearing interest at an effective rate of
14.16%, and has drawn down $3,236,000 to date. In conjunction with this
agreement, the Company issued warrants to purchase 125,000 shares of the
Company's Series D1 redeemable convertible preferred stock at a price of $2.85
per share, which expire in June 2003. The fair value of the warrants,
calculated using the Black-Scholes option pricing model, using the assumptions
described in Note 5, is not material.

</TABLE>
 
  Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered
hereby, if any are taken.
 
  The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at
such price less a concession of $   per share. The Underwriters may allow, and
such dealers may reallow, a concession of not in excess of $   per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time
to time be varied by the representatives.
 
  The Company and the Selling Stockholders have granted the Underwriters an
option exercisable for 30 days after the date of this Prospectus to purchase
up to an aggregate of      additional shares of Common Stock at the initial
public offering price per share, less the underwriting discount, solely to
cover over-allotments, if any. If the Underwriters exercise their over-
allotment option, the Underwriters have severally agreed, subject to certain
conditions, to purchase approximately the same percentage thereof that the
number of shares to be purchased by each of them, as shown in the foregoing
table, bears to the      shares of Common Stock offered hereby.
 
  The Company has agreed that, during the period beginning from the date of
this Prospectus and continuing to and including the date 180 days after the
date of this Prospectus, it will not offer, sell, contract to sell or
otherwise dispose of any securities of the Company (other than pursuant to
employee stock option or stock purchase plans existing, or on the conversion
or exchange of convertible or exchangeable securities outstanding, on the date
of this Prospectus) which are substantially similar to the Common Stock or
which are convertible into or exchangeable for securities which are
substantially similar to the Common Stock without the prior written consent of
the representatives, except for the shares of Common Stock offered in
connection with the offering.
 
  In addition, the Company's officers and directors and all holders of shares
of capital stock and warrants of the Company have agreed that they will not
offer, sell or otherwise dispose of any shares of Common Stock owned of record
or beneficially as of the date of the Prospectus, including securities
convertible into or exercisable or exchangeable for shares of Common Stock as
of said date, as well as any shares of Common Stock later acquired by reason
of the conversion, exercise or exchange of
 
                                      U-1
<PAGE>
 
such securities, or enter into any swap or other transaction with respect to
the shares that would transfer the economic consequences of ownership of the
Common Stock to another person, for a period of 180 days following the date of
this Prospectus, except that such persons may dispose of shares of Common
Stock as bona fide gifts if the recipient of any such gift agrees in writing
with the Underwriters to be bound by the terms of this 180-day transfer
restriction.
 
  The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed 5% of the total number of shares of Common
Stock offered by them.
 
  Prior to the offering, there has been no public market for the shares. The
initial public offering price will be negotiated among the Company, the
representatives of the Underwriters and the representatives of the Selling
Stockholders. Among the factors to be considered in determining the initial
public offering price of the Common Stock, in addition to prevailing market
conditions, will be the Company's historical performance, estimates of the
business potential and earnings prospects of the Company, an assessment of the
Company's management and the consideration of the above factors in relation to
market valuation of companies in related business.
 
  In connection with the offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Common Stock; and syndicate short positions involve
the sale by the Underwriters of a greater number of shares of Common Stock
than they are required to purchase from the Company in the offering. The
Underwriters also may impose a penalty bid, whereby selling concessions
allowed to syndicate members or other broker-dealers in respect of the
securities sold in the offering for their account may be reclaimed by the
syndicate if such shares of Common Stock are repurchased by the syndicate in
stabilizing or covering transactions. These activities may stabilize, maintain
or otherwise affect the market price of the Common Stock which may be higher
than the price that might otherwise prevail in the open market; and these
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the Nasdaq National Market, in the over-the-counter market
or otherwise.
 
  Application has been made for quotation of the Common Stock on the Nasdaq
National Market under the symbol "EXDS." The Company and, to the extent the
over-allotment option is exercised, the Selling Stockholders have agreed to
indemnify the several Underwriters against certain liabilities, including
liabilities under the Securities Act.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors to the Registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith
or that involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the Delaware General Corporation Law or (iv) for any
transaction from which the director derived an improper personal benefit. In
addition, as permitted by Section 145 of the Delaware General Corporation Law,
the Bylaws of the Registrant provide that: (i) the Registrant is required to
indemnify its directors and executive officers to the fullest extent permitted
by the Delaware General Corporation Law; (ii) the Registrant may, in its
discretion, indemnify other officers, employees and agents as set forth in the
Delaware General Corporation Law; (iii) upon receipt of an undertaking to
repay such advances if indemnification is determined to be unavailable, the
Registrant is required to advance expenses, as incurred, to its directors and
executive officers to the fullest extent permitted by the Delaware General
Corporation Law in connection with a proceeding (except if a determination is
reasonably and promptly made by the Board of Directors by a majority vote of a
quorum consisting of directors who were not parties to the proceeding or, in
certain circumstances, by independent legal counsel in a written opinion that
the facts known to the decision-making party demonstrate clearly and
convincingly that such person acted in bad faith or in a manner that such
person did not believe to be in, or not opposed to, the best interests of the
corporation); (iv) the rights conferred in the Bylaws are not exclusive and
the Registrant is authorized to enter into indemnification agreements with its
directors, officers and employees and agents; (v) the Registrant may not
retroactively amend the Bylaw provisions relating to indemnity; and (vi) to
the fullest extent permitted by the Delaware General Corporation Law, a
director or executive officer will be deemed to have acted in good faith and
in a manner he or she reasonably believed to be in, or not opposed to, the
best interests of the Registrant and, with respect to any criminal action or
proceeding, to have had no reasonable cause to believe that his or her conduct
was unlawful if his or her action is based on the records or books of account
of the corporation or on information supplied to him or her by officers of the
corporation in the course of
 
                                     II-1
<PAGE>
 
their duties or on the advice of legal counsel for the corporation or on
information or records given or reports made to the corporation by independent
certified public accountants or appraisers or other experts.
 
  The Registrant's policy is to enter into indemnification agreements with
each of its directors and executive officers. The indemnification agreements
provide that directors and executive officers will be indemnified and held
harmless to the fullest possible extent permitted by law including against all
expenses (including attorneys' fees), judgments, fines and settlement amounts
paid or reasonably incurred by them in any action, suit or proceeding,
including any derivative action by or in the right of the Registrant, on
account of their services as directors, officers, employees or agents of the
Registrant or as directors, officers, employees or agents of any other company
or enterprise when they are serving in such capacities at the request of the
Registrant. The Registrant will not be obligated pursuant to the agreements to
indemnify or advance expenses to an indemnified party with respect to
proceedings or claims (i) initiated or brought voluntarily by the indemnified
party and not by way of defense, except with respect to a proceeding to
establish or enforce a right to indemnify under the indemnification agreements
or any other agreement or insurance policy or under the Registrant's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
indemnification, or authorized by the Board of Directors or as otherwise
required under Delaware statute or law, regardless of whether the indemnified
party is ultimately determined to be entitled to such indemnification, (ii)
for expenses and the payment of profits arising from the purchase and sale by
the indemnified party of securities in violation of Section 16(b) of the
Securities Exchange Act of 1934 or any similar successor statute or (iii) if a
final decision by a court having jurisdiction in the matter shall determine
that such indemnification is not lawful.
 
  The indemnification agreement also provides for contribution in certain
situations in which the Registrant and a director or executive officer are
jointly liable but indemnification is unavailable, such contribution to be
based on the relative benefits received and the relative fault of the
Registrant and the director or executive officer. No contribution is allowed
to a person found guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act of 1933) from any person who was not
found guilty of such fraudulent misrepresentation.
 
  The indemnification agreement requires a director or executive officer to
reimburse the Registrant for all expenses advanced only to the extent it is
ultimately determined that the director or executive officer is not entitled,
under Delaware law, the Bylaws, the indemnification agreement or otherwise, to
be indemnified for such expenses. The form of indemnification agreement
provides that it is not exclusive of any rights a director or executive
officer may have under the Certificate of Incorporation, Bylaws, other
agreements, any majority-in-interest vote of the stockholders or vote of
disinterested directors, Delaware law or otherwise.
 
  The indemnification provision in the Bylaws, and the form of indemnification
agreements entered into between the Registrant and its directors and executive
officers, may be sufficiently broad to permit indemnification of the
Registrant's executive officers and directors for liabilities arising under
the Securities Act of 1933, as amended (the "Securities Act").
 
  As authorized by the Registrant's Bylaws, the Registrant, with approval by
the Board, expects to purchase director and officer liability insurance.
 
  In addition, Mr. Mocarski is indemnified in certain circumstances by Fleet
Financial Group, Inc.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                                                                   ----      
applicable, and all other material terms and conditions (including but not
limited to the terms and conditions applicable to such options by virtue of each
of the Exodus California 1995 Stock Option Plan and the Exodus California 1997
Equity Incentive Plan).  Continuous employment with Exodus California will be
credited to an optionee for purposes of determining the vesting of the number of

Stock or series of Preferred Stock will be issued in connection with the Merger.
In lieu thereof, Exodus Delaware shall pay each shareholder of Exodus California

Common Stock or series of Preferred Stock (assuming the aggregation of all

fair market value of a share of Exodus Delaware Common Stock or series of
Preferred Stock, as the case may be, as determined by the Board of Directors of
Exodus Delaware in good faith (the "Fair Market Value Per Share").  Upon
                                    ---------------------------         
exercise of each assumed option of Exodus California to purchase Exodus Delaware
Common Stock, cash will be paid by Exodus Delaware in lieu of any fractional
share of Exodus Delaware Common Stock issuable upon exercise of such option, and
the amount of cash received for such fractional share shall be the

                                       3

Fair Market Value Per Share upon exercise thereof multiplied by the applicable

                                  ARTICLE II

                                  ARTICLE III

          A.   Classes of Stock. The corporation is authorized to issue two
               ----------------
classes of stock to be designated, respectively, "COMMON STOCK" and "PREFERRED
STOCK." The total number of shares which the corporation is authorized to issue
is one hundred twenty-eight million, two hundred forty-one thousand, seven

eighty-one thousand, five hundred seventy-nine (53,281,579) shares shall be

hundred and twenty-four (74,960,124) shares shall be Preferred Stock, of which
seven million, seven hundred and ninety-eight thousand, four hundred and eighty-
three (7,798,483) shares have been designated "SERIES A PREFERRED STOCK," seven
million, seven hundred and ninety-eight thousand, four hundred and eighty-three

               ---------------
Preferred Stock, the Series B Preferred Stock, the Series B1 Preferred Stock,
the Series C Preferred Stock, the Series C1 Preferred Stock, the Series D
Preferred Stock and Series D1 Preferred Stock are
<PAGE>
 
hereinafter collectively referred to as the "PREFERRED STOCK" and shall have the
rights, preferences and privileges set forth below in Article III (C).

          C.   Rights, Preferences and Restrictions of Preferred Stock. The
               -------------------------------------------------------
Preferred Stock authorized by these Amended and Restated Articles of
Incorporation may be issued from time to time in one or more series. The Board
of Directors is hereby authorized to fix or alter the rights, preferences,
privileges and restrictions granted to or imposed upon additional series of
Preferred Stock, and the number of shares constituting any such series and the
designation thereof, or of any of them. Subject to compliance with applicable
protective voting rights which have been or may be granted to the Preferred
Stock or series thereof in Certificates of Determination or the corporation's
Amended and Restated Articles of Incorporation ("PROTECTIVE PROVISIONS"), the
privileges, preferences and restrictions of any such additional series may be
subordinated to, pari passu with (including, without limitation, inclusion in
                 ---- -----
provisions with respect to liquidation and acquisition preferences, redemption
and/or approval of matters by vote or written consent), or senior to any of
those of any present or future class or series of Preferred or Common Stock;
provided, however that no additional series of Preferred Stock senior to any
existing series of Preferred Stock may be issued without the approval of the
holders of at least a majority of the then outstanding shares of such affected
series of Preferred Stock. Subject to compliance with applicable Protective
Provisions, the Board of Directors is also authorized to increase or decrease
the number of shares of any series (other than the Series A, Series A1, Series
B, Series B1, Series C, Series C1, Series D and Series D1 Preferred Stock),
prior or subsequent to the issue of that series, but not below the number of
shares of such series then outstanding. In case the number of shares of any
series shall be so decreased, the shares constituting such decrease shall resume
the status which they had prior to the adoption of the resolution originally
fixing the number of shares of such series.

          1.   Dividend Provisions. The holders of shares of Preferred Stock
               -------------------
shall be entitled to receive dividends, out of any assets legally available
therefor, prior and in preference to any declaration or payment of any dividend
(payable other than in Common Stock or other securities and rights convertible
into or entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock of the corporation, each of such securities to
be hereinafter referred to as a "COMMON STOCK DIVIDEND") on the Common Stock of
the corporation, at the annual rate for each series of Preferred Stock set forth
in the following sentence. The annual dividend rate of the Series A and Series
A1 Preferred Stock shall be $0.04 per share, the annual dividend rate of the
Series B and Series B1 Preferred Stock shall be $0.084 per share, the annual
dividend rate of the Series C and Series C1 Preferred Stock shall be $0.095 per
share and the annual dividend rate of the Series D and Series D1 Preferred Stock
shall be $0.20 per share. Dividends on the Series A, Series A1, Series B and
Series B1 Preferred Stock shall be payable when and if declared by the Board of
Directors and shall not be cumulative. Dividends on the Series C, Series C1,
Series D and Series D1 Preferred Stock shall accrue, and be compounded annually
and be cumulative but shall be payable only (i) in the event and at the time of
a liquidation, dissolution or winding up of the corporation pursuant to Article
III, Section C(2)(a) or (ii) on declaration and payment of any dividends with
respect to any outstanding securities of the corporation (other than a Common
Stock Dividend). No dividends (other than a Common Stock Dividend) shall be paid
with respect to the Common Stock unless dividends in the total amount of the
annual dividend rate for each series of Preferred Stock shall have first been
paid or declared and set apart for payment to the holders of such Preferred
Stock. Payments

                                       2
<PAGE>
 
of any dividends to the holders of shares of Preferred Stock shall be paid pro
rata, on an equal priority, pari passu basis, according to their respective
                            ---- -----                                     
dividend preferences as set forth herein.

          2.      Liquidation Preference.
                  ---------------------- 

          (a)     In the event of any liquidation, dissolution or winding up of
the corporation, either voluntary or involuntary, the holders of shares of
Preferred Stock shall be entitled to receive, subsequent to payment by the
corporation of any amounts due to any holders of Preferred Stock who have
previously requested redemption pursuant to the terms of section 3 herein, and
prior and in preference to any distribution of any of the assets of the
corporation to the holders of Common Stock by reason of their ownership thereof,
an amount per share equal to the sum of (i) $0.4129 for each outstanding share
of Series A Preferred Stock and Series A1 Preferred Stock (the "ORIGINAL SERIES
A ISSUE PRICE" and "ORIGINAL SERIES A1 ISSUE PRICE," respectively), (ii) $0.84
for each outstanding share of Series B Preferred Stock and Series B1 Preferred
Stock (the "ORIGINAL SERIES B ISSUE PRICE" and "ORIGINAL SERIES B1 ISSUE PRICE,"
respectively), (iii) $1.3623 for each outstanding share of Series C Preferred
Stock and Series C1 Preferred Stock (the "ORIGINAL SERIES C ISSUE PRICE" and
"ORIGINAL SERIES C1 ISSUE PRICE", respectively), (iv) $2.85 for each outstanding
share of Series D Preferred Stock and Series D1 Preferred Stock (the "ORIGINAL
SERIES D ISSUE PRICE" and "ORIGINAL SERIES D1 ISSUE PRICE" and (v) an amount
equal to all declared and/or accrued but unpaid dividends on such shares. If
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Preferred Stock shall be insufficient to permit the payment
to such holders of the full aforesaid preferential amounts, then, the entire
assets and funds of the corporation legally available for distribution shall be
distributed among the holders of the Preferred Stock pro rata, on an equal
priority, pari passu basis, according to their respective liquidation
          ---- -----     
preferences as set forth herein.

          (b)     After the distributions described in subsection (a) above have
been paid, the remaining assets of the corporation available for distribution,
if any, to shareholders shall be distributed among the holders of the Common
Stock pro rata based on the number of shares of Common Stock held by each.

          (c)(i)  For purposes of this Section 2, a liquidation, dissolution or
winding up of the corporation shall be deemed to be occasioned by, or to include
but not be limited to, (A) the acquisition of the corporation by another entity,
(B) the acquisition of greater than 50% of the then outstanding voting
securities of the corporation by persons or entities unrelated to and not
affiliated with the holders thereof in a transaction or series of related
transactions where the corporation is a party; or (C) a sale of all or
substantially all of the assets of the corporation by means of any transaction
or series of related transactions (including, without limitation, any
reorganization, merger or consolidation but, excluding any merger effected
exclusively for the purpose of changing the domicile of the corporation); unless
                                                                          ------
in each case the corporation's shareholders of record as constituted immediately
prior to such acquisition or sale will, immediately after such acquisition or
sale (by virtue of securities issued as consideration for the corporation's
acquisition or sale or otherwise) hold at least 50% of the voting power of the
surviving or acquiring entity.

             (ii) In any of such events, if the consideration received by the
corporation is other than cash, its value will be deemed its fair market value.
Any securities shall be valued as follows:

                                       3
<PAGE>
 
                    (A)  If traded on a securities exchange or through the
Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the securities on such exchange over the thirty-day period
ending three (3) days prior to the closing;

                    (B)  If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                    (C)  If there is no active public market, the value shall be
the fair market value thereof as determined in this Section 2(c)(ii)(C) ("FAIR
MARKET VALUE"). Fair Market Value shall be initially determined by a majority of
those directors of the corporation who are not affiliated with any of the
holders of such Preferred Stock (the "DISINTERESTED DIRECTORS"). If the holders
of a majority of the Preferred Stock (the "CONTESTING HOLDERS") notify the
Disinterested Directors within five (5) days after receiving notification of the
Disinterested Directors' determination of the Fair Market Value of such
securities that they object to their determination of the Fair Market Value of
the securities received by the corporation, the Disinterested Directors and the
Contesting Holders shall attempt to agree on the Fair Market Value of such
securities. In the event that the Disinterested Directors and the Contesting
Holders fail to agree on the Fair Market Value of such securities within fifteen
(15) days after receipt by the Disinterested Directors of the objection notice
referred to above, the Disinterested Directors and the Contesting Holders shall
select an independent appraiser, who shall be a nationally recognized investment
banking firm, or another entity mutually acceptable to all parties, to conduct
an appraisal of the relevant securities, which appraisal shall determine the
Fair Market Value (without making any discount for lack of transferability or
minority interests) of such securities. If the Disinterested Directors and the
Contesting Holders are unable to agree on the selection of an independent
appraiser within fifteen (15) days after the commencement of such selection
process, then an independent appraiser meeting the specifications described
above shall be selected by the American Arbitration Association in the San
Francisco Bay Area, California. The independent appraiser shall then promptly
conduct an appraisal to determine the Fair Market Value of the relevant
securities. In such case, the Fair Market Value shall be that as is determined
by the appraiser. Such appraisal shall be paid for equally by the corporation
and the Contesting Holders.

          (iii)     In the event the requirements of this subsection 2(c) are
not complied with, the corporation shall forthwith either:

               (A)  Cause such closing to be postponed until such time as the
requirements of this Section 2 have been complied with; or

               (B)  Cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in subsection 2(c)(iv) hereof.

          (iv)      The corporation shall give each holder of record of
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the shareholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing

                                       4
<PAGE>
 
of such transaction, whichever is earlier, and shall also notify such holders in
writing of the final approval of such transaction.  The first of such notices
shall describe the material terms and conditions of the impending transaction
and the provisions of this Section 2, and the corporation shall thereafter give
such holders prompt notice of any material changes.  The transaction shall in no
event take place sooner than twenty (20) days after the corporation has given
the first notice provided for herein or sooner than ten (10) days after the
corporation has given notice of any material changes provided for herein;
provided, however, that such periods may be shortened upon the written consent
of the holders of Preferred Stock that are entitled to such notice rights or
similar notice rights and that represent at least a majority of the voting power
of all then outstanding shares of Preferred Stock.

          3.   Redemption.
               ---------- 

          (a)  At any time after June 25, 2002 (the "FIRST REDEMPTION DATE"),
but within thirty (30) days after the receipt by the corporation of a written
request from the holders of the then outstanding shares of Series A, Series A1,
Series B and Series B1 Preferred Stock (the "OUTSTANDING A/B PREFERRED"), that a
number equal to up to fifty percent (50%) of the number of shares of Outstanding
A/B Preferred be redeemed, and concurrently with surrender by such holders of
the certificates representing such shares, the corporation shall, to the extent
it may lawfully do so, redeem up to fifty percent (50%) of the Outstanding A/B
Preferred on the First Redemption Date by paying in cash therefor a sum per
share equal to (i) the Original Series A Issue Price per share of Series A
Preferred Stock, (ii) the Original Series A1 Issue Price per share of Series A1
Preferred Stock, (iii) the Original Series B Issue Price per share of Series B
Preferred Stock or (iv) the Original Series B1 Issue Price per share of Series
B1 Preferred Stock, (as adjusted for any stock dividends, combinations or splits
with respect to such shares) plus all declared but unpaid dividends on such
shares (the "SERIES A REDEMPTION PRICE," "SERIES A1 REDEMPTION PRICE," "SERIES B
REDEMPTION PRICE," and "SERIES B1 REDEMPTION PRICE," provided, however, that
                                                     --------- -------
the corporation shall not be required to redeem such shares unless and until the
number of shares to be redeemed pursuant to this subsection 3(a) equals or
exceeds twenty percent (20%) of the Outstanding A/B Preferred. Any redemption
effected pursuant to this subsection 3(a) shall be made on a pro rata basis
among the holders of the Outstanding A/B Preferred in proportion to the number
of shares of the Outstanding A/B Preferred for which redemption has been
requested.

          (b)  At any time after June 25, 2003 (the "SECOND REDEMPTION DATE"),
but within thirty (30) days after the receipt by the corporation of a written
request from the holders of the Outstanding A/B Preferred, that up to all of
such holders' shares be redeemed, and concurrently with surrender by such
holders of the certificates representing such shares, the corporation shall, to
the extent it may lawfully do so, redeem up to all shares held by such holders
on the Second Redemption Date by paying in cash therefor a sum per share equal
to (i) the Series A Redemption Price, (ii) the Series A1 Redemption Price, (iii)
the Series B Redemption Price or (iv) the Series B1 Redemption Price, provided,
                                                                      --------
however, that the corporation shall not be required to redeem such shares unless
- -------
and until the number of shares to be redeemed pursuant to this subsection 3(b)
equals or exceeds twenty percent (20%) of the Outstanding A/B Preferred. Any
redemption effected pursuant to this subsection 3(b) shall be made on a pro rata
basis among the holders of the Outstanding A/B Preferred in proportion to the
number of shares of Outstanding A/B Preferred for which redemption has been
requested.

                                       5

          (c)  At any time after the First Redemption Date but within thirty
(30) days after the receipt by the corporation of a written request from the
holders of the then outstanding shares of Series C, Series C1, Series D and
Series D1 Preferred Stock (the "OUTSTANDING C/D PREFERRED"), that a number equal
to fifty percent (50%) of the number of shares of the Outstanding C/D Preferred
be redeemed, and concurrently with surrender by such holders of the certificates
representing such shares, the corporation shall, to the extent it may lawfully
do so, redeem up to fifty percent (50%) of the Outstanding C/D Preferred on the
First Redemption Date by paying in cash therefor a sum per share equal to(i) the
greater of (a) the Original Series C/D Issue Price (and all accrued but unpaid
dividends on such share) per share of Series C/D Preferred Stock and (b) the
Fair Market Value of the Series C/D Preferred Stock, or (ii) the greater of (a)
the Original Series C1/D1 Issue Price (and all accrued but unpaid dividends on
such share) per share of Series C1/D1 Preferred Stock and (b) the Fair Market
Value of the Series C1/D1 Preferred Stock (as adjusted for any stock dividends,
combinations or splits with respect to such shares) plus all declared but unpaid
dividends on such shares (the "SERIES C REDEMPTION PRICE," "SERIES C1 REDEMPTION
PRICE," "SERIES D REDEMPTION PRICE," and "SERIES D1 REDEMPTION PRICE."),
provided, however, that the corporation shall not be required to redeem such
- --------- -------
shares unless and until the number of shares to be redeemed pursuant to this
subsection 3(c) equals or exceeds twenty percent (20%) of the Outstanding C/D
Preferred. Any redemption effected pursuant to this subsection 3(c) shall be
made on a pro rata basis among the holders of the Outstanding C/D Preferred in
proportion to the number of shares of Outstanding C/D Preferred for which
redemption has been requested.

          (d)  At any time after the Second Redemption Date but within thirty
(30) days after the receipt by the corporation of a written request from the
holders of the Outstanding C/D Preferred, that up to all of such holders' shares
be redeemed, and concurrently with surrender by such holders of the certificates
representing such shares, the corporation shall, to the extent it may lawfully
do so, redeem up to all shares held by such holders on the Second Redemption
Date by paying in cash therefor the Series C/D Redemption Price or the Series
C1/D1 Redemption Price, provided, however, that the corporation shall not be
                        --------- ------- 
required to redeem such shares unless and until the number of shares to be
redeemed pursuant to this subsection 3(d) equals or exceeds twenty percent (20%)
of the Outstanding C/D Preferred. Any redemption effected pursuant to this
subsection 3(d) shall be made on a pro rata basis among the holders of the
Outstanding C/D Preferred in proportion to the number of shares of Outstanding
C/D Preferred for which redemption has been requested.

          (e)  At least fifteen (15) but no more than thirty (30) days prior to
each Redemption Date, written notice shall be mailed, first class postage
prepaid, to each holder of record (at the close of business on the business day
next preceding the day on which notice is given) of the Preferred Stock to be
redeemed, at the address last shown on the records of the corporation for such
holder, notifying such holder of the redemption to be effected, specifying the
number of shares to be redeemed from such holder, the Redemption Date, the
Redemption Price, the place at which payment may be obtained and calling upon
such holder to surrender to the corporation, in the manner and at the place
designated, his, her or its certificate or certificates representing the shares
to be redeemed (the "REDEMPTION NOTICE"). Except as provided in subsection
(3)(g) on or after the Redemption Date, each holder of Preferred Stock to be
redeemed shall surrender to the corporation the certificate or certificates
representing such shares, in the manner and at the place designated in the
Redemption Notice, and thereupon the Redemption Price of such shares shall be
payable to the order of the person whose name appears on such

                                       6
<PAGE>
 
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled, provided that, in the event an appraisal of the
Fair Market Value of the Series C, Series C1, Series D or Series D1 Preferred
Stock is required, the corporation shall not pay the Redemption Price to any
holder of Preferred Stock until such Fair Market Value determination has been
made. In the event less than all the shares represented by any such certificate
are redeemed, a new certificate shall be issued representing the unredeemed
shares.

          (f)  Upon, but not until, the payment of the Redemption Price in full
with respect to a share of Preferred Stock, the rights of the holder of such
share of Preferred Stock designated for redemption in the Redemption Notice
(except the right to receive the Redemption Price without interest upon
surrender of their certificate or certificates other than as provided in
paragraph (g) below) shall cease with respect to such share, and such share
shall not thereafter be transferred on the books of the corporation or be deemed
to be outstanding for any purpose whatsoever. If the funds of the corporation
legally available for redemption of shares of Preferred Stock on any Redemption
Date are insufficient to redeem the total number of shares of Preferred Stock to
be redeemed on such date, those funds which are legally available will be used
to redeem the maximum possible number of such shares ratably among the holders
of such shares to be redeemed based upon the aggregate Redemption Price to be
received by such holder. The shares of Preferred Stock not redeemed shall remain
outstanding and entitled to all the rights and preferences provided herein. At
any time thereafter when additional funds of the corporation are legally
available for the redemption of shares of Preferred Stock, such funds will
immediately be used to redeem the balance of the shares which the corporation
has become obliged to redeem on any Redemption Date but which it has not
redeemed.

          (g)  In the event the Series C, Series C1, Series D or Series D1
Redemption Price is not paid in full within 30 days of the applicable Redemption
Date, and such payment is not prohibited by law, interest shall accrue on the
remaining outstanding Series C Redemption Price and the Series D Redemption
Price at the rate of 7% per annum from such 30th day until the Series C, Series
C1, Series D or Series D1 Redemption Price and all interest accrued thereon
shall be paid in full.

          (h)  In the event that any holder makes a request for redemption
pursuant to any provision of this Section 3, the corporation shall, within five
(5) business days of such redemption request, provide notice of such redemption
request to all other holders entitled at that time to redeem their shares.

          (i)  For the avoidance of doubt, in the event that the corporation
receives a request for redemption pursuant to this Section 3 and, subsequent
thereto but prior to payment in full of the relevant Redemption Price there is a
liquidation, dissolution or winding up of the corporation, the amount payable
with respect to the unredeemed shares with respect to which redemption has been
requested shall be determined pursuant to this Section 3 and not pursuant to
Section 2.

          4.   Conversion Rights. The outstanding shares of Preferred Stock
               -----------------
shall be convertible into Common Stock as follows (the "CONVERSION RIGHTS"):

          (a)  Optional Conversion.
               ------------------- 

                                       7
<PAGE>
 
               (i)  At the option of the holder thereof, each share of Preferred
Stock shall be convertible, at any time or from time to time prior to the close
of business on the business day before the date of redemption of such share,
into fully paid and nonassessable shares of Common Stock as provided herein.

               (ii) Each holder of Preferred Stock who elects to convert the
same into shares of Common Stock shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the corporation or any transfer agent
for the Preferred Stock or Common Stock, and shall give written notice to the
corporation at such office that such holder elects to convert the same and shall
state therein the number of shares of Preferred Stock being converted. Thereupon
the corporation shall promptly issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled upon such conversion. In the event that any holder
converts a number of shares less than the number stated on such holder's stock
certificate, the corporation shall deliver to such holder a new certificate
representing the remaining unconverted shares. Such conversion shall be deemed
to have been made immediately prior to the close of business on the date of such
surrender of the certificate or certificates representing the shares of
Preferred Stock to be converted, and the person entitled to receive the shares
of Common Stock issuable upon such conversion shall be treated for all purposes
as the record holder of such shares of Common Stock on such date.

          (b)  Automatic Conversion.  Each share of Preferred Stock shall
               --------------------                                      
automatically be converted into fully paid and nonassessable shares of Common
Stock, as provided herein (i) immediately prior to the closing of a firm
commitment public offering underwritten by a nationally recognized investment
bank pursuant to an effective registration statement filed under the Securities
Act of 1933, as amended (the "SECURITIES ACT"), covering the offer and sale of
Common Stock for the account of the corporation in which the aggregate public
offering price (before deduction of underwriters' discounts and commissions)
equals or exceeds $30,000,000 and the public offering price per share of which
equals or exceeds $3.25 per share before deduction of underwriters' discounts
and commissions (such price per share of Common Stock to be appropriately
adjusted to reflect Common Stock Events (as defined below)), provided that such
offering is priced for sale to the general public not later than April 30, 1998
(the public offering price per share will be $5.00 if pricing does not occur by
such date), and such Common Stock shall be listed on the Nasdaq National Market,
the American Stock Exchange, the New York Stock Exchange or other national
securities market or exchange (a "QUALIFIED IPO"); or (ii) the date specified by
written consent or agreement of (a) with respect to the Series A and A1
Preferred Stock, the holders of a majority of the then outstanding shares of
Series A Preferred Stock and Series A1 Preferred Stock, voting as a single
class, (b) with respect to the Series B and B1 Preferred Stock, the holders of a
majority of the then outstanding shares of Series B Preferred Stock and Series
B1 Preferred Stock, voting together as a single class, (c) with respect to the
Series C and C1 Preferred Stock, the holders of two-thirds of the then
outstanding shares of Series C Preferred Stock and Series C1 Preferred Stock,
voting together as a single class and (d) with respect to the Series D and D1
Preferred Stock, the holders of two-thirds of the then outstanding shares of
Series D Preferred Stock and Series D1 Preferred Stock, voting together as a
single class.

               (i)  Upon the occurrence of any event specified in subparagraph
4(b)(i) or (ii) above, the outstanding shares of Preferred Stock shall be
converted into Common Stock automatically without the need for any further
action by the holders of such shares and whether or not the certificates
representing such shares are surrendered to the corporation or its transfer

                                       8
<PAGE>
 
agent; provided, however, that the corporation shall not be obligated to issue
       --------- -------
certificates evidencing the shares of Common Stock issuable upon such conversion
unless the certificates evidencing such shares of Preferred Stock are either
delivered to the corporation or its transfer agent as provided below, or the
holder notifies the corporation or its transfer agent that such certificates
have been lost, stolen or destroyed and executes an agreement satisfactory to
the corporation to indemnify the corporation from any loss incurred by it in
connection with such certificates. Upon the occurrence of such automatic
conversion of the Preferred Stock, the holders of Preferred Stock shall
surrender the certificates representing such shares at the office of the
corporation or any transfer agent for the Preferred Stock or Common Stock.
Thereupon, there shall be issued and delivered to such holder promptly at such
office and in its name as shown on such surrendered certificate or certificates,
a certificate or certificates for the number of shares of Common Stock into
which the shares of Preferred Stock surrendered were convertible on the date on
which such automatic conversion occurred.

          (c)  Conversion Price.  Each share of Preferred Stock shall be
               ----------------                                         
convertible in accordance with subsection 4(a) or subsection 4(b) above into the
number of shares of Common Stock which results from dividing the Original Issue
Price for such series of Preferred Stock by the conversion price for such series
of Preferred Stock that is in effect at the time of conversion (the "CONVERSION
PRICE").  The initial Conversion Price for the Series A Preferred Stock shall be
the Original Series A Issue Price, the initial Conversion Price for the Series
A1 Preferred Stock shall be the Original Series A1 Issue Price, the initial
Conversion Price for the Series B Preferred Stock shall be the Original Series B
Issue Price, the initial Conversion Price for the Series B1 Preferred Stock
shall be the Original Series B1 Issue Price, the initial Conversion Price for
the Series C Preferred Stock shall be the Original Series C Issue Price, the
initial Conversion Price for the Series C1 Preferred Stock shall be the Original
Series C1 Issue Price, the initial Conversion Price for the Series D Preferred
Stock shall be the Original Series D Issue Price and the initial Conversion
Price for the Series D1 Preferred Stock shall be the Original D1 Issue Price.
The Conversion Price of each series of Preferred Stock shall be subject to
adjustment from time to time as provided below.

          (d)  Adjustment Upon Common Stock Event. At any time after such series
               ----------------------------------
of Preferred Stock was first issued (the "PURCHASE DATE" with respect to such
series) upon the happening of a Common Stock Event (as hereinafter defined), the
Conversion Price of the Series A Preferred Stock, the Conversion Price of the
Series A1 Preferred Stock, the Conversion Price of the Series B Preferred Stock,
the Conversion Price of the Series B1 Preferred Stock, the Conversion Price of
the Series C Preferred Stock, the Conversion Price of the Series C1 Preferred
Stock, the Conversion Price of the Series D Preferred Stock and the Conversion
Price of the Series D1 Preferred Stock shall, simultaneously with the happening
of such Common Stock Event, be adjusted by multiplying the Conversion Price of
such series of Preferred Stock in effect immediately prior to such Common Stock
Event by a fraction, (i) the numerator of which shall be the number of shares of
Common Stock issued and outstanding immediately prior to such Common Stock
Event, and (ii) the denominator of which shall be the number of shares of Common
Stock issued and outstanding immediately after such Common Stock Event, and the
product so obtained shall thereafter be the Conversion Price for such series of
Preferred Stock.  The Conversion Price for a series of Preferred Stock shall be
readjusted in the same manner upon the happening of each subsequent Common Stock
Event.  As used herein, the term "COMMON STOCK EVENT" shall mean (i) the issue
by the corporation of additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, (ii) a subdivision of the outstanding
shares of Common Stock into a greater number of shares of

                                       9
<PAGE>
 
Common Stock, or (iii) a combination of the outstanding shares of Common Stock
into a smaller number of shares of Common Stock.

          (e)  Adjustments for Other Dividends and Distributions. If at any time
               -------------------------------------------------
or from time to time after the Purchase Date the corporation pays a dividend or
makes another distribution to the holders of the Common Stock payable in
securities of the corporation other than shares of Common Stock, then in each
such event provision shall be made so that the holders of the Series A Preferred
Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series B1 Preferred
Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series D Preferred
Stock and Series D1 Preferred Stock shall receive upon conversion thereof, in
addition to the number of shares of Common Stock receivable upon conversion
thereof, the amount of securities of the corporation which they would have
received had their Preferred Stock been converted into Common Stock on the date
of such event (or such record date, as applicable) and had they thereafter,
during the period from the date of such event (or such record date, as
applicable) to and including the conversion date, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 4 with respect to
the rights of the holders of the Preferred Stock or with respect to such other
securities by their terms.

          (f)  Adjustment for Reclassification, Exchange and Substitution. If at
               ----------------------------------------------------------
any time or from time to time after the Original Issue Date the Common Stock
issuable upon the conversion of the Series A Preferred Stock, Series A1
Preferred Stock, Series B Preferred Stock, Series B1 Preferred Stock, Series C
Preferred Stock, Series C1 Preferred Stock, Series D Preferred Stock and Series
D1 Preferred Stock is changed into the same or a different number of shares of
any class or classes of stock, whether by recapitalization, reclassification or
otherwise (other than by a Common Stock Event or a stock dividend,
           ----- ----                                             
reorganization, merger, consolidation or sale of assets provided for elsewhere
in this Section 4), then in any such event each holder of Series A Preferred
Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series B1 Preferred
Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series D Preferred
Stock and Series D1 Preferred Stock shall have the right thereafter to convert
such stock into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification or other change by
holders of the number of shares of Common Stock into which such shares of Series
A Preferred Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series
B1 Preferred Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series
D Preferred Stock and Series D1 Preferred Stock could have been converted
immediately prior to such recapitalization, reclassification or change, all
subject to further adjustment as provided herein or with respect to such other
securities or property by the terms thereof.

          (g)  Sale of Shares Below Conversion Price.
               ------------------------------------- 

               (i)  Adjustment Formula. If at any time or from time to time
                    ------------------
after the Original Issue Date the corporation issues or sells, or is deemed by
the provisions of this subsection 4(g) to have issued or sold, Additional Shares
of Common Stock (as hereinafter defined), otherwise than in connection with a
Common Stock Event as provided in subsection 4(d), a dividend or distribution as
provided in subsection 4(e) or a recapitalization, reclassification or other
change as provided in subsection 4(f), for an Effective Price (as hereinafter
defined) that is less than the Conversion Price for the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock in effect immediately prior to such issue or sale, then, and in each such
case, the Conversion Price for such series of 

                                       10
<PAGE>
 
Preferred Stock shall be reduced, as of the close of business on the date of
such issue or sale, to the price obtained by multiplying such Conversion Price
by a fraction:

                    (x)  The numerator of which shall be the sum of (A) the
number of Common Stock Equivalents Outstanding (as hereinafter defined)
immediately prior to such issue or sale of Additional Shares of Common Stock
plus (B) the quotient obtained by dividing the Aggregate Consideration Received
(as hereinafter defined) by the corporation for the total number of Additional
Shares of Common Stock so issued or sold (or deemed so issued and sold) by the
Conversion Price for such series of Preferred Stock in effect immediately prior
to such issue or sale; and

                    (y)  The denominator of which shall be the sum of (A) the
number of Common Stock Equivalents Outstanding immediately prior to such issue
or sale plus (B) the number of Additional Shares of Common Stock so issued or
sold (or deemed so issued and sold).

               (ii) Certain Definitions.  For the purpose of making any
                    -------------------    
adjustment required under this subsection 4(g):

                    (1)  "ADDITIONAL SHARES OF COMMON STOCK" shall mean all
shares of Common Stock issued by the corporation, whether or not subsequently
reacquired or retired by the corporation, other than: (A) shares of Common Stock
issued or issuable upon conversion of Series A Preferred Stock, Series A1
Preferred Stock, Series B Preferred Stock, Series B1 Preferred Stock, Series C
Preferred Stock, Series C1 Preferred Stock, Series D Preferred Stock or Series
D1 Preferred Stock; and (B) a total of 7,438,900 shares of Common Stock (or
options, warrants or rights therefor) issued to employees, officers, or
directors of, or contractors, consultants or advisers to, the corporation or any
Subsidiary pursuant to stock purchase or stock option plans, stock bonuses or
awards, warrants, contracts or other arrangements that are approved by at least
seventy five percent (75%) of the Board (such number of shares to be calculated
net of any repurchases of such shares by the corporation and net of any such
expired or terminated options, warrants or rights and to be proportionally
adjusted to reflect any subsequent Common Stock Event);

                    (2)  The "AGGREGATE CONSIDERATION RECEIVED" by the
corporation for any issue or sale (or deemed issue or sale) of securities shall
(A) to the extent it consists of cash, be computed at the gross amount of cash
received by the corporation before deduction of any underwriting or similar
commissions, compensation or concessions paid or allowed by the corporation in
connection with such issue or sale and without deduction of any expenses payable
by the corporation in connection with any such issuance and sale; (B) to the
extent it consists of property other than cash, be computed at the fair value of
that property as determined in good faith by the unanimous approval of the
Board; and (C) if Additional Shares of Common Stock, Convertible Securities or
Rights or Options to purchase either Additional Shares of Common Stock or
Convertible Securities are issued or sold together with other stock or
securities or other assets of the corporation for a consideration which covers
both, be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the unanimous approval of the Board to be
allocable to such Additional Shares of Common Stock, Convertible Securities or
Rights or Options.

                                       11
<PAGE>
 
                    (3)  "COMMON STOCK EQUIVALENTS OUTSTANDING" shall mean the
number of shares of Common Stock that is equal to the sum of (A) all shares of
Common Stock of the corporation that are outstanding at the time in question,
plus (B) all shares of Common Stock of the corporation issuable upon conversion
of all shares of Preferred Stock or other Convertible Securities that are
outstanding at the time in question, plus (C) all shares of Common Stock of the
corporation that are issuable upon the exercise of Rights or Options that are
outstanding at the time in question assuming the full conversion or exchange
into Common Stock of all such Rights or Options that are Rights or Options to
purchase or acquire Convertible Securities into or for Common Stock.

                    (4)  "CONVERTIBLE SECURITIES" shall mean stock or other
securities convertible into or exchangeable for shares of Common Stock.

                    (5)  The "EFFECTIVE PRICE" of Additional Shares of Common
Stock shall mean the quotient determined by dividing the total number of
Additional Shares of Common Stock issued or sold, or deemed to have been issued
or sold, by the corporation under this subsection 4(g), into the Aggregate
Consideration Received, or deemed to have been received, by the corporation
under this subsection 4(g), for the issue of such Additional Shares of Common
Stock;

                    (6)  "RIGHTS OR OPTIONS" shall mean warrants, options or
other rights to purchase or acquire shares of Common Stock or Convertible
Securities.

             (iii)  Deemed Issuances. For the purpose of making any adjustment
                    ----------------
to the Conversion Price of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock required under this
subsection 4(g), if the corporation issues or sells any Rights or Options or
Convertible Securities and if the Effective Price of the shares of Common Stock
issuable upon exercise of such Rights or Options and/or the conversion or
exchange of Convertible Securities (computed without reference to any additional
or similar protective or antidilution clauses) is less than the Conversion Price
then in effect for a series of Preferred Stock, then the corporation shall be
deemed to have issued, at the time of the issuance of such Rights, Options or
Convertible Securities, that number of Additional Shares of Common Stock that is
equal to the maximum number of shares of Common Stock issuable upon exercise or
conversion of such Rights, Options or Convertible Securities upon their issuance
and to have received, as the Aggregate Consideration Received for the issuance
of such shares, an amount equal to the total amount of the consideration, if
any, received by the corporation for the issuance of such Rights or Options or
Convertible Securities, plus, in the case of such Rights or Options, the minimum
amounts of consideration, if any, payable to the corporation upon the exercise
in full of such Rights or Options, plus, in the case of Convertible Securities,
the minimum amounts of consideration, if any, payable to the corporation (other
than by cancellation of liabilities or obligations evidenced by such Convertible
Securities) upon the conversion or exchange thereof; provided that:
                                                     -------- ---- 

                    (1)  if the minimum amounts of such consideration cannot be
ascertained, but are a function of antidilution or similar protective clauses,
then the corporation shall be deemed to have received the amount determined in
good faith by the unanimous approval of the Board;

                                       12
<PAGE>
 
                    (2)  if the minimum amount of consideration payable to the
corporation upon the exercise of Rights or Options or the conversion or exchange
of Convertible Securities is reduced over time or upon the occurrence or non-
occurrence of specified events other than by reason of antidilution or similar
protective adjustments, then the Effective Price shall be recalculated using the
figure to which such minimum amount of consideration is reduced; and

                    (3)  if the minimum amount of consideration payable to the
corporation upon the exercise of such Rights or Options or the conversion or
exchange of Convertible Securities is subsequently increased, then the Effective
Price shall again be recalculated using the increased minimum amount of
consideration payable to the corporation upon the exercise of such Rights or
Options or the conversion or exchange of such Convertible Securities.

          No further adjustment of the Conversion Price, adjusted upon the
issuance of such Rights or Options or Convertible Securities, shall be made as a
result of the actual issuance of shares of Common Stock on the exercise of any
such Rights or Options or the conversion or exchange of any such Convertible
Securities.  If any such Rights or Options or the conversion rights represented
by any such Convertible Securities shall expire without having been fully
exercised, then the Conversion Price as adjusted upon the issuance of such
Rights or Options or Convertible Securities shall be readjusted to the
Conversion Price which would have been in effect had an adjustment been made on
the basis that the only shares of Common Stock so issued were the shares of
Common Stock, if any, that were actually issued or sold on the exercise of such
Rights or Options or rights of conversion or exchange of such Convertible
Securities, and such shares of Common Stock, if any, were issued or sold for the
consideration actually received by the corporation upon such exercise, plus the
consideration, if any, actually received by the corporation for the granting of
all such Rights or Options, whether or not exercised, plus the consideration
received for issuing or selling all such Convertible Securities actually
converted or exchanged, plus the consideration, if any, actually received by the
corporation (other than by cancellation of liabilities or obligations evidenced
by such Convertible Securities) on the conversion or exchange of such
Convertible Securities, provided that such readjustment shall not apply to prior
conversions of Preferred Stock.

remain unissued after such issuance (other than any such shares reserved for
issuance upon exercise of then outstanding warrants for such shares), and (ii)
to create and reserve for issuance upon Special Mandatory Conversion of any
Series A Preferred Stock a new series of Preferred Stock equal in number to the
number of shares of Series A1 Preferred Stock so canceled and designated Series
A2 Preferred Stock with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series A1 Preferred Stock, except that the Conversion Price for such
shares of Series A2 Preferred Stock once initially issued shall be the Series A
Conversion Price in effect immediately prior to such issuance;

                    (2)  in the case of an issuance of Series B1 Preferred
Stock, (i) to cancel all authorized shares of Series B1 Preferred Stock that
remain unissued after such issuance (other than any such shares reserved for

in number to the number of shares of Series C1 Preferred Stock so canceled and
designated Series C2 Preferred Stock with the designations, powers, preferences
and rights and the qualifications, limitations and restrictions identical to
those then applicable to the Series C1 Preferred Stock, except that the
Conversion Price for such shares of Series C2 Preferred Stock once initially

such issuance;

                    (4)  in the case of an issuance of Series D1 Preferred

               The corporation shall take the same actions with respect to the
Series A2, Series B2 and Series C2 Preferred Stock and each subsequently
authorized series of Preferred Stock upon initial issuance of shares of the last
such series to be authorized. The right to receive any dividend declared but
unpaid at the time of conversion on any shares of Preferred Stock converted
pursuant to the provisions of this subsection 4(k) shall accrue to the benefit
of the new shares of Preferred Stock issued upon conversion thereof.

          5.   Voting Rights. The holder of each share of Preferred Stock shall
               -------------

holder shall have full voting rights and powers equal to the voting rights and
powers of the holders of Common Stock, and shall be entitled, notwithstanding
any provision hereof, to notice of any shareholders' meeting in accordance with

holder could be converted) shall be rounded to the nearest whole number (with
one-half being rounded upward).

such shares are issued but not outstanding, may not be reissued as shares of
such series or as shares of the class of Preferred Stock.  Upon the retirement
of any such shares and the filing of a certificate of retirement pursuant to
Sections 103 and 243 of the Delaware General Corporation Law with respect
thereto, the shares of such series shall be eliminated and the number of shares
of Preferred Stock shall be reduced accordingly.

     The business and affairs of the corporation shall be managed by or under
the direction of the Board of Directors.  The number of directors shall be fixed
from time to time exclusively by a resolution of the Board of Directors adopted
by the affirmative vote of a majority of the total number of directors that the
corporation would have if there were no vacancies.

     Any vacancy on the Board of Directors, however resulting, and any newly
created directorships resulting from any increase in the authorized number of
directors shall be filled only by the affirmative vote of a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director, unless the Board of Directors determines that any such vacancies or
newly created directorships shall be filled by the stockholders.

     The Board of Directors of the corporation shall have the power to adopt,
amend or repeal Bylaws of the corporation.

                                  ARTICLE VI

     Any action required or permitted to be taken by the stockholders of the
corporation may be effected at a duly called annual or special meeting of such
holders or by consent in writing by such holders.  Subject to the rights of the
holders of any class or series of Preferred Stock, special meetings of
stockholders of the corporation shall be called only by the Board of Directors
or upon the request of the Chairman of the Board of Directors or the Chief
Executive Officer of the corporation.  If a special meeting is requested by the
Chairman of the Board of Directors or the Chief Executive Officer, the Board of
Director shall determine the time and the place of such meeting, which shall be
called for no less than 35 days nor more than 120 days after the receipt by the
Secretary of the corporation of the request for such meeting.

     Election of directors need not be by written ballot unless the Bylaws of
the corporation shall so provide.

shares of Common Stock of the corporation, each of such securities to be

Preferred Stock shall be payable when and if declared by the Board of Directors
and shall not be cumulative.  Dividends on the Series C, Series C1, Series D and

liquidation, dissolution or winding up of the corporation pursuant to Article
III, Section C(2)(a) or (ii) on declaration and payment of any dividends with
respect to any outstanding securities of the corporation (other than a Common
Stock Dividend).  No dividends (other than a Common Stock Dividend) shall be
paid with respect to the Common Stock unless dividends in the total amount of
the annual dividend rate for each series of Preferred Stock shall have first
been paid or declared and set apart for payment to the holders of such Preferred
Stock.  Payments of any dividends to the holders of shares of Preferred Stock
shall be paid pro rata, on an equal priority, pari passu basis, according to
                                              ---- -----                    
their respective dividend preferences as set forth herein.

     3.   Liquidation Preference.
          ---------------------- 

          (a)    In the event of any liquidation, dissolution or winding up of
the corporation, either voluntary or involuntary, the holders of shares of
Preferred Stock shall be entitled to receive, subsequent to payment by the
corporation of any amounts due to any holders of Preferred Stock who have
previously requested redemption pursuant to the terms of section 4 herein, and
prior and in preference to any distribution of any of the assets of the
corporation to the holders of Common Stock by reason of their ownership thereof,
an amount per share equal to the sum of (i) $0.4129 for each outstanding share
of Series A Preferred Stock and Series A1 Preferred Stock (the "Original Series
A Issue Price" and "Original Series A1 Issue Price," respectively), (ii) $0.84
for each outstanding share of Series B Preferred Stock and Series B1 Preferred
Stock (the "Original Series B Issue Price" and "Original Series B1 Issue Price,"
respectively), (iii) $1.3623 for each outstanding share of Series C Preferred
Stock and Series C1 Preferred Stock (the "Original Series C Issue Price" and
"Original Series C1 Issue Price", respectively), (iv) $2.85 for each outstanding
share of Series D Preferred Stock and Series D1 Preferred Stock (the "Original
Series D Issue Price" and "Original Series D1 Issue Price" and (v) an amount
equal to all declared and/or accrued but unpaid dividends on such shares. If
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Preferred Stock shall be insufficient to permit the payment
to such holders of the full aforesaid preferential amounts, then, the entire
assets and funds of the corporation legally available for distribution shall be
distributed among the holders of the Preferred Stock pro rata, on an equal
priority, pari passu basis, according to their respective liquidation
          ---- -----                                                 
preferences as set forth herein.

          (b)    After the distributions described in subsection (a) above have
been paid, the remaining assets of the corporation available for distribution,
if any, to shareholders shall be distributed among the holders of the Common
Stock pro rata based on the number of shares of Common Stock held by each.

          (c)(i) For purposes of this Section 3, a liquidation, dissolution or
winding up of the corporation shall be deemed to be occasioned by, or to include
but not be limited to, (A) the acquisition of the corporation by another entity,
(B) the acquisition of greater than 50% of the then outstanding voting
securities of the corporation by persons or entities unrelated to and not
affiliated with the holders thereof in a transaction or series of related
transactions where the corporation is a party; or (C) a sale of all or
substantially all of the assets of the corporation by means of any transaction
or series of related transactions (including, without limitation, any

                                       3
<PAGE>
 
reorganization, merger or consolidation but, excluding any merger effected
exclusively for the purpose of changing the domicile of the corporation); unless
                                                                          ------
in each case the corporation's shareholders of record as constituted immediately
prior to such acquisition or sale will, immediately after such acquisition or
sale (by virtue of securities issued as consideration for the corporation's
acquisition or sale or otherwise) hold at least 50% of the voting power of the
surviving or acquiring entity.

               (ii)  In any of such events, if the consideration received by the
corporation is other than cash, its value will be deemed its fair market value.
Any securities shall be valued as follows:

                     (A) If traded on a securities exchange or through the
Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the securities on such exchange over the thirty-day period
ending three (3) days prior to the closing;

                     (B) If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty-day period ending three (3) days prior to the
closing; and

                     (C) If there is no active public market, the value shall be
the fair market value thereof as determined in this Section 3(c)(ii)(C) ("Fair
Market Value"). Fair Market Value shall be initially determined by a majority of
those directors of the corporation who are not affiliated with any of the
holders of such Preferred Stock (the "Disinterested Directors"). If the holders
of a majority of the Preferred Stock (the "Contesting Holders") notify the
Disinterested Directors within five (5) days after receiving notification of the
Disinterested Directors' determination of the Fair Market Value of such
securities that they object to their determination of the Fair Market Value of
the securities received by the corporation, the Disinterested Directors and the
Contesting Holders shall attempt to agree on the Fair Market Value of such
securities. In the event that the Disinterested Directors and the Contesting
Holders fail to agree on the Fair Market Value of such securities within fifteen
(15) days after receipt by the Disinterested Directors of the objection notice
referred to above, the Disinterested Directors and the Contesting Holders shall
select an independent appraiser, who shall be a nationally recognized investment
banking firm, or another entity mutually acceptable to all parties, to conduct
an appraisal of the relevant securities, which appraisal shall determine the
Fair Market Value (without making any discount for lack of transferability or
minority interests) of such securities. If the Disinterested Directors and the
Contesting Holders are unable to agree on the selection of an independent
appraiser within fifteen (15) days after the commencement of such selection
process, then an independent appraiser meeting the specifications described
above shall be selected by the American Arbitration Association in the San
Francisco Bay Area, California. The independent appraiser shall then promptly
conduct an appraisal to determine the Fair Market Value of the relevant
securities. In such case, the Fair Market Value shall be that as is determined
by the appraiser. Such appraisal shall be paid for equally by the corporation
and the Contesting Holders.

               (iii) In the event the requirements of this subsection 3(c) are
not complied with, the corporation shall forthwith either:

               (A)   Cause such closing to be postponed until such time as the
requirements of this Section 3 have been complied with; or

                                       4
<PAGE>
 
               (B)   Cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in subsection 3 (c)(iv)
hereof.

               (iv)  The corporation shall give each holder of record of
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the shareholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 3, and the corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the corporation has given the first notice
provided for herein or sooner than ten (10) days after the corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of Preferred
Stock that are entitled to such notice rights or similar notice rights and that
represent at least a majority of the voting power of all then outstanding shares
of Preferred Stock.

     4.   Redemption.
          ---------- 

          (a)  At any time after June 25, 2002 (the "First Redemption Date"),

exceeds twenty percent (20%) of the Outstanding A/B Preferred. Any redemption

among the holders of the Outstanding A/B Preferred in proportion to the number
of shares of the Outstanding A/B Preferred for which redemption has been
requested.

          (b)  At any time after June 25, 2003 (the "Second Redemption Date"),

such holders' shares be redeemed, and concurrently with surrender by such
holders of the certificates representing such shares, the corporation shall, to

Redemption Price or (iv) the Series B1 Redemption Price, provided, however, that
                                                         --------- ------- 
the corporation shall not be required to redeem such shares unless and until the
number of shares to be redeemed pursuant to this subsection 4(b) equals or
exceeds twenty percent (20%) of the Outstanding A/B Preferred. Any redemption
effected pursuant to this subsection 4(b) shall be made on a pro rata basis
among the holders of the Outstanding A/B Preferred in proportion to the number
of shares of Outstanding A/B Preferred for which redemption has been requested.

          (c)  At any time after the First Redemption Date but within thirty
(30) days after the receipt by the corporation of a written request from the
holders of the then outstanding shares of Series C, Series C1, Series D and
Series D1 Preferred Stock (the "Outstanding C/D Preferred"), that a number equal
to fifty percent (50%) of the number of shares of the Outstanding C/D Preferred
be redeemed, and concurrently with surrender by such holders of the certificates
representing such shares, the corporation shall, to the extent it may lawfully
do so, redeem up to fifty percent (50%) of the Outstanding C/D Preferred on the
First Redemption Date by paying in cash therefor a sum per share equal to(i) the
greater of (a) the Original Series C/D Issue Price (and all accrued but unpaid
dividends on such share) per share of Series C/D Preferred Stock and (b) the
Fair Market Value of the Series C/D Preferred Stock, or (ii) the greater of (a)

provided, however, that the corporation shall not be required to redeem such
- --------- -------                                   
shares unless and until the number of shares to be redeemed pursuant to this
subsection 4(c) equals or exceeds twenty percent (20%) of the Outstanding C/D
Preferred. Any redemption effected pursuant to this subsection 4(c) shall be
made on a pro rata basis among the holders of the Outstanding C/D Preferred in
proportion to the number of shares of Outstanding C/D Preferred for which
redemption has been requested.

          (d)  At any time after the Second Redemption Date but within thirty
(30) days after the receipt by the corporation of a written request from the
holders of the Outstanding C/D Preferred, that up to all of such holders' shares
be redeemed, and concurrently with surrender by such holders of the certificates
representing such shares, the corporation shall, to the extent it may lawfully
do so, redeem up to all shares held by such holders on the Second Redemption
Date by paying in cash therefor the Series C/D Redemption Price or the Series
C1/D1 Redemption Price, provided, however, that the corporation shall not be 
                        --------- -------          
required to redeem such shares unless and until the number of shares to be
redeemed pursuant to this subsection 4(d) equals or exceeds twenty percent (20%)
of the Outstanding C/D Preferred. Any redemption effected pursuant to this
subsection 4(d) shall be made on a pro rata basis among the holders of the
Outstanding C/D Preferred in proportion to the number of shares of Outstanding
C/D Preferred for which redemption has been requested.

          (e)  At least fifteen (15) but no more than thirty (30) days prior to
each Redemption Date, written notice shall be mailed, first class postage
prepaid, to each holder of record (at the close of business on the business day
next preceding the day on which notice is given) of the Preferred Stock to be
redeemed, at the address last shown on the records of the corporation for such
holder, notifying such holder of the redemption to be effected, specifying the
number of shares to be redeemed from such holder, the Redemption Date, the
Redemption Price, the place at which payment may be obtained and calling upon
such holder to surrender to

                                       6
<PAGE>
 
the corporation, in the manner and at the place designated, his, her or its
certificate or certificates representing the shares to be redeemed (the
"Redemption Notice"). Except as provided in subsection (4)(g) on or after the
Redemption Date, each holder of Preferred Stock to be redeemed shall surrender
to the corporation the certificate or certificates representing such shares, in
the manner and at the place designated in the Redemption Notice, and thereupon
the Redemption Price of such shares shall be payable to the order of the person
whose name appears on such certificate or certificates as the owner thereof and
each surrendered certificate shall be canceled, provided that, in the event an
appraisal of the Fair Market Value of the Series C, Series C1, Series D or
Series D1 Preferred Stock is required, the corporation shall not pay the
Redemption Price to any holder of Preferred Stock until such Fair Market Value
determination has been made. In the event less than all the shares represented
by any such certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.

          (f)  Upon, but not until, the payment of the Redemption Price in full
with respect to a share of Preferred Stock, the rights of the holder of such
share of Preferred Stock designated for redemption in the Redemption Notice
(except the right to receive the Redemption Price without interest upon
surrender of their certificate or certificates other than as provided in
paragraph (g) below) shall cease with respect to such share, and such share
shall not thereafter be transferred on the books of the corporation or be deemed
to be outstanding for any purpose whatsoever. If the funds of the corporation
legally available for redemption of shares of Preferred Stock on any Redemption
Date are insufficient to redeem the total number of shares of Preferred Stock to
be redeemed on such date, those funds which are legally available will be used
to redeem the maximum possible number of such shares ratably among the holders
of such shares to be redeemed based upon the aggregate Redemption Price to be
received by such holder. The shares of Preferred Stock not redeemed shall remain
outstanding and entitled to all the rights and preferences provided herein. At
any time thereafter when additional funds of the corporation are legally
available for the redemption of shares of Preferred Stock, such funds will
immediately be used to redeem the balance of the shares which the corporation
has become obliged to redeem on any Redemption Date but which it has not
redeemed.

          (g)  In the event the Series C, Series C1, Series D or Series D1
Redemption Price is not paid in full within 30 days of the applicable Redemption
Date, and such payment is not prohibited by law, interest shall accrue on the
remaining outstanding Series C Redemption Price and the Series D Redemption
Price at the rate of 7% per annum from such 30th day until the Series C, Series
C1, Series D or Series D1 Redemption Price and all interest accrued thereon
shall be paid in full.

          (h)  In the event that any holder makes a request for redemption
pursuant to any provision of this Section 4, the corporation shall, within five
(5) business days of such redemption request, provide notice of such redemption
request to all other holders entitled at that time to redeem their shares.

          (i)  For the avoidance of doubt, in the event that the corporation
receives a request for redemption pursuant to this Section 4 and, subsequent
thereto but prior to payment in full of the relevant Redemption Price there is a
liquidation, dissolution or winding up of the corporation, the amount payable
with respect to the unredeemed shares with respect to which redemption has been
requested shall be determined pursuant to this Section 4 and not pursuant to
Section 3.

     5.   Conversion Rights.  The outstanding shares of Preferred Stock shall be
          -----------------                                                     
convertible into Common Stock as follows (the "CONVERSION RIGHTS"):

          (a)  Optional Conversion.
               ------------------- 

               (i)   At the option of the holder thereof, each share of
Preferred Stock shall be convertible, at any time or from time to time prior to
the close of business on the business day before the date of redemption of such
share, into fully paid and nonassessable shares of Common Stock as provided
herein.

               (ii)  Each holder of Preferred Stock who elects to convert the
same into shares of Common Stock shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the corporation or any transfer agent
for the Preferred Stock or Common Stock, and shall give written notice to the
corporation at such office that such holder elects to convert the same and shall
state therein the number of shares of Preferred Stock being converted. Thereupon
the corporation shall promptly issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled upon such conversion. In the event that any holder
converts a number of shares less than the number stated on such holder's stock
certificate, the corporation shall deliver to such holder a new certificate
representing the remaining unconverted shares. Such conversion shall be deemed
to have been made immediately prior to the close of business on the date of such
surrender of the certificate or certificates representing the shares of
Preferred Stock to be converted, and the person entitled to receive the shares
of Common Stock issuable upon such conversion shall be treated for all purposes
as the record holder of such shares of Common Stock on such date.

          (b)  Automatic Conversion.  Each share of Preferred Stock shall
               --------------------                                      
automatically be converted into fully paid and nonassessable shares of Common
Stock, as provided herein (i) immediately prior to the closing of a firm
commitment public offering underwritten by a nationally recognized investment
bank pursuant to an effective registration statement filed under the Securities
Act of 1933, as amended (the "Securities Act"), covering the offer and sale of
Common Stock for the account of the corporation in which the aggregate public
offering price (before deduction of underwriters' discounts and commissions)
equals or exceeds $30,000,000 and the public offering price per share of which
equals or exceeds $8.55 per share before deduction of underwriters' discounts
and commissions (such price per share of Common Stock to be appropriately
adjusted to reflect Common Stock Events (as defined below)), provided that such
offering is priced for sale to the general public not later than April 30, 1998
(the public offering price per share will be $15.00 if pricing does not occur by
such date), and such Common Stock shall be listed on the Nasdaq National Market,
the American Stock Exchange, the New York Stock Exchange or other national
securities market or exchange (a "Qualified IPO"); or (ii) the date specified by
written consent or agreement of (a) with respect to the Series A and A1
Preferred Stock, the holders of a majority of the then outstanding shares of
Series A Preferred Stock and Series A1 Preferred Stock, voting as a single
class, (b) with respect to the Series B and B1 Preferred Stock, the holders of a
majority of the then outstanding shares of Series B Preferred Stock and Series
B1 Preferred Stock, voting together as a single class, (c) with respect to the
Series C and C1 Preferred Stock, the holders of two-thirds of the then
outstanding shares of Series C Preferred Stock and Series C1 Preferred Stock,
voting together as a single class and (d) with respect to the Series D and D1
Preferred Stock, the holders of two-thirds of the then

                                       8
<PAGE>
 
outstanding shares of Series D Preferred Stock and Series D1 Preferred Stock,
voting together as a single class.

               (i)   Upon the occurrence of any event specified in subparagraph
4(b)(i) or (ii) above, the outstanding shares of Preferred Stock shall be
converted into Common Stock automatically without the need for any further
action by the holders of such shares and whether or not the certificates
representing such shares are surrendered to the corporation or its transfer
agent; provided, however, that the corporation shall not be obligated to issue
       --------  -------                                                      
certificates evidencing the shares of Common Stock issuable upon such conversion
unless the certificates evidencing such shares of Preferred Stock are either
delivered to the corporation or its transfer agent as provided below, or the
holder notifies the corporation or its transfer agent that such certificates
have been lost, stolen or destroyed and executes an agreement satisfactory to
the corporation to indemnify the corporation from any loss incurred by it in
connection with such certificates. Upon the occurrence of such automatic
conversion of the Preferred Stock, the holders of Preferred Stock shall
surrender the certificates representing such shares at the office of the
corporation or any transfer agent for the Preferred Stock or Common Stock.
Thereupon, there shall be issued and delivered to such holder promptly at such
office and in its name as shown on such surrendered certificate or certificates,
a certificate or certificates for the number of shares of Common Stock into
which the shares of Preferred Stock surrendered were convertible on the date on
which such automatic conversion occurred.

          (c)  Conversion Price.  Each share of Preferred Stock shall be
               ----------------                                         
convertible in accordance with subsection 5(a) or subsection 5(b) above into the
number of shares of Common Stock which results from dividing the Original Issue
Price for such series of Preferred Stock by the conversion price for such series
of Preferred Stock that is in effect at the time of conversion (the "Conversion
Price").  The initial Conversion Price for the Series A Preferred Stock shall be
the Original Series A Issue Price, the initial Conversion Price for the Series
A1 Preferred Stock shall be the Original Series A1 Issue Price, the initial
Conversion Price for the Series B Preferred Stock shall be the Original Series B
Issue Price, the initial Conversion Price for the Series B1 Preferred Stock
shall be the Original Series B1 Issue Price, the initial Conversion Price for
the Series C Preferred Stock shall be the Original Series C Issue Price, the
initial Conversion Price for the Series C1 Preferred Stock shall be the Original
Series C1 Issue Price, the initial Conversion Price for the Series D Preferred
Stock shall be the Original Series D Issue Price and the initial Conversion
Price for the Series D1 Preferred Stock shall be the Original D1 Issue Price.
The Conversion Price of each series of Preferred Stock shall be subject to
adjustment from time to time as provided below.

          (d)  Adjustment Upon Common Stock Event.  At any time after such 
               ----------------------------------                          
series of Preferred Stock was first issued (the "Purchase Date" with respect to
such series) upon the happening of a Common Stock Event (as hereinafter
defined), the Conversion Price of the Series A Preferred Stock, the Conversion
Price of the Series A1 Preferred Stock, the Conversion Price of the Series B
Preferred Stock, the Conversion Price of the Series B1 Preferred Stock, the
Conversion Price of the Series C Preferred Stock, the Conversion Price of the
Series C1 Preferred Stock, the Conversion Price of the Series D Preferred Stock
and the Conversion Price of the Series D1 Preferred Stock shall, simultaneously
with the happening of such Common Stock Event, be adjusted by multiplying the
Conversion Price of such series of Preferred Stock in effect immediately prior
to such Common Stock Event by a fraction, (i) the numerator of which shall be
the number of shares of Common Stock issued and outstanding immediately prior to
such Common Stock Event, and (ii) the denominator of which shall be the number
of shares of

                                       9
<PAGE>
 
Common Stock issued and outstanding immediately after such Common Stock Event,
and the product so obtained shall thereafter be the Conversion Price for such
series of Preferred Stock.  The Conversion Price for a series of Preferred Stock
shall be readjusted in the same manner upon the happening of each subsequent
Common Stock Event.  As used herein, the term "Common Stock Event" shall mean
(i) the issue by the corporation of additional shares of Common Stock as a
dividend or other distribution on outstanding Common Stock, (ii) a subdivision
of the outstanding shares of Common Stock into a greater number of shares of
Common Stock, or (iii) a combination of the outstanding shares of Common Stock
into a smaller number of shares of Common Stock.

          (e)  Adjustments for Other Dividends and Distributions.  If at any 
               -------------------------------------------------             
time or from time to time after the Purchase Date the corporation pays a
dividend or makes another distribution to the holders of the Common Stock
payable in securities of the corporation other than shares of Common Stock, then
in each such event provision shall be made so that the holders of the Series A
Preferred Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series B1
Preferred Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series D
Preferred Stock and Series D1 Preferred Stock shall receive upon conversion
thereof, in addition to the number of shares of Common Stock receivable upon
conversion thereof, the amount of securities of the corporation which they would
have received had their Preferred Stock been converted into Common Stock on the
date of such event (or such record date, as applicable) and had they thereafter,
during the period from the date of such event (or such record date, as
applicable) to and including the conversion date, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 5 with respect to
the rights of the holders of the Preferred Stock or with respect to such other
securities by their terms.

          (f)  Adjustment for Reclassification, Exchange and Substitution.  If
               ----------------------------------------------------------     
at any time or from time to time after the Original Issue Date the Common Stock
issuable upon the conversion of the Series A Preferred Stock, Series A1
Preferred Stock, Series B Preferred Stock, Series B1 Preferred Stock, Series C
Preferred Stock, Series C1 Preferred Stock, Series D Preferred Stock and Series
D1 Preferred Stock is changed into the same or a different number of shares of
any class or classes of stock, whether by recapitalization, reclassification or
otherwise (other than by a Common Stock Event or a stock dividend,
           ----- ----                                             
reorganization, merger, consolidation or sale of assets provided for elsewhere
in this Section 5), then in any such event each holder of Series A Preferred
Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series B1 Preferred
Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series D Preferred
Stock and Series D1 Preferred Stock shall have the right thereafter to convert
such stock into the kind and amount of stock and other securities and property
receivable upon such recapitalization, reclassification or other change by
holders of the number of shares of Common Stock into which such shares of Series
A Preferred Stock, Series A1 Preferred Stock, Series B Preferred Stock, Series
B1 Preferred Stock, Series C Preferred Stock, Series C1 Preferred Stock, Series
D Preferred Stock and Series D1 Preferred Stock could have been converted
immediately prior to such recapitalization, reclassification or change, all
subject to further adjustment as provided herein or with respect to such other
securities or property by the terms thereof.

          (g)  Sale of Shares Below Conversion Price.
               ------------------------------------- 

               (i)   Adjustment Formula.  If at any time or from time to time 
                     ------------------                             
after the Original Issue Date the corporation issues or sells, or is deemed by
the provisions of this

                                       10
<PAGE>
 
subsection 5(g) to have issued or sold, Additional Shares of Common Stock (as
hereinafter defined), otherwise than in connection with a Common Stock Event as
provided in subsection 5(d), a dividend or distribution as provided in
subsection 5(e) or a recapitalization, reclassification or other change as
provided in subsection 5(f), for an Effective Price (as hereinafter defined)
that is less than the Conversion Price for the Series A Preferred Stock, Series
B Preferred Stock, Series C Preferred Stock or Series D Preferred Stock in
effect immediately prior to such issue or sale, then, and in each such case, the
Conversion Price for such series of Preferred Stock shall be reduced, as of the
close of business on the date of such issue or sale, to the price obtained by
multiplying such Conversion Price by a fraction:

                     (x) The numerator of which shall be the sum of (A) the
number of Common Stock Equivalents Outstanding (as hereinafter defined)
immediately prior to such issue or sale of Additional Shares of Common Stock
plus (B) the quotient obtained by dividing the Aggregate Consideration Received
(as hereinafter defined) by the corporation for the total number of Additional
Shares of Common Stock so issued or sold (or deemed so issued and sold) by the
Conversion Price for such series of Preferred Stock in effect immediately prior
to such issue or sale; and

                     (y) The denominator of which shall be the sum of (A) the
number of Common Stock Equivalents Outstanding immediately prior to such issue
or sale plus (B) the number of Additional Shares of Common Stock so issued or
sold (or deemed so issued and sold).

               (ii)  Certain Definitions.  For the purpose of making any 
                     -------------------
adjustment required under this subsection 5(g):

          (1)  "Additional Shares of Common Stock" shall mean all shares of
Common Stock issued by the corporation, whether or not subsequently reacquired
or retired by the corporation, other than: (A) shares of Common Stock issued or
issuable upon conversion of Series A Preferred Stock, Series A1 Preferred Stock,
Series B Preferred Stock, Series B1 Preferred Stock, Series C Preferred Stock,
Series C1 Preferred Stock, Series D Preferred Stock or Series D1 Preferred
Stock; and (B) a total of 7,438,900 shares of Common Stock (or options, warrants
or rights therefor) issued to employees, officers, or directors of, or
contractors, consultants or advisers to, the corporation or any Subsidiary
pursuant to stock purchase or stock option plans, stock bonuses or awards,
warrants, contracts or other arrangements that are approved by at least seventy
five percent (75%) of the Board (such number of shares to be calculated net of
any repurchases of such shares by the corporation and net of any such expired or
terminated options, warrants or rights and to be proportionally adjusted to
reflect any subsequent Common Stock Event);

          (2)  The "Aggregate Consideration Received" by the corporation for any
issue or sale (or deemed issue or sale) of securities shall (A) to the extent it
consists of cash, be computed at the gross amount of cash received by the
corporation before deduction of any underwriting or similar commissions,
compensation or concessions paid or allowed by the corporation in connection
with such issue or sale and without deduction of any expenses payable by the
corporation in connection with any such issuance and sale; (B) to the extent it
consists of property other than cash, be computed at the fair value of that
property as determined in good faith by the unanimous approval of the Board; and
(C) if Additional Shares of Common Stock, Convertible Securities or Rights or
Options to purchase either Additional Shares of Common

                                       11
<PAGE>
 
Stock or Convertible Securities are issued or sold together with other stock or
securities or other assets of the corporation for a consideration which covers
both, be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the unanimous approval of the Board to be
allocable to such Additional Shares of Common Stock, Convertible Securities or
Rights or Options.

          (3)  "Common Stock Equivalents Outstanding" shall mean the number of
shares of Common Stock that is equal to the sum of (A) all shares of Common
Stock of the corporation that are outstanding at the time in question, plus (B)
all shares of Common Stock of the corporation issuable upon conversion of all
shares of Preferred Stock or other Convertible Securities that are outstanding
at the time in question, plus (C) all shares of Common Stock of the corporation
that are issuable upon the exercise of Rights or Options that are outstanding at
the time in question assuming the full conversion or exchange into Common Stock
of all such Rights or Options that are Rights or Options to purchase or acquire
Convertible Securities into or for Common Stock.

          (4)  "Convertible Securities" shall mean stock or other securities
convertible into or exchangeable for shares of Common Stock.

          (5)  The "Effective Price" of Additional Shares of Common Stock shall
mean the quotient determined by dividing the total number of Additional Shares
of Common Stock issued or sold, or deemed to have been issued or sold, by the
corporation under this subsection 5(g), into the Aggregate Consideration
Received, or deemed to have been received, by the corporation under this
subsection 5(g), for the issue of such Additional Shares of Common Stock;

          (6)  "Rights or Options" shall mean warrants, options or other rights
to purchase or acquire shares of Common Stock or Convertible Securities.

               (iii) Deemed Issuances.  For the purpose of making any adjustment
                     ----------------    
to the Conversion Price of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock required under this
subsection 5(g), if the corporation issues or sells any Rights or Options or
Convertible Securities and if the Effective Price of the shares of Common Stock
issuable upon exercise of such Rights or Options and/or the conversion or
exchange of Convertible Securities (computed without reference to any additional
or similar protective or antidilution clauses) is less than the Conversion Price
then in effect for a series of Preferred Stock, then the corporation shall be
deemed to have issued, at the time of the issuance of such Rights, Options or
Convertible Securities, that number of Additional Shares of Common Stock that is
equal to the maximum number of shares of Common Stock issuable upon exercise or
conversion of such Rights, Options or Convertible Securities upon their issuance
and to have received, as the Aggregate Consideration Received for the issuance
of such shares, an amount equal to the total amount of the consideration, if
any, received by the corporation for the issuance of such Rights or Options or
Convertible Securities, plus, in the case of such Rights or Options, the minimum
amounts of consideration, if any, payable to the corporation upon the exercise
in full of such Rights or Options, plus, in the case of Convertible Securities,
the minimum amounts of consideration, if any, payable to the corporation (other
than by cancellation of liabilities or obligations evidenced by such Convertible
Securities) upon the conversion or exchange thereof; provided that:
                                                     -------- ---- 

                                       12
<PAGE>
 
          (1)  if the minimum amounts of such consideration cannot be
ascertained, but are a function of antidilution or similar protective clauses,
then the corporation shall be deemed to have received the amount determined in
good faith by the unanimous approval of the Board;

          (2)  if the minimum amount of consideration payable to the corporation
upon the exercise of Rights or Options or the conversion or exchange of
Convertible Securities is reduced over time or upon the occurrence or non-
occurrence of specified events other than by reason of antidilution or similar
protective adjustments, then the Effective Price shall be recalculated using the
figure to which such minimum amount of consideration is reduced; and

          (3)  if the minimum amount of consideration payable to the corporation
upon the exercise of such Rights or Options or the conversion or exchange of
Convertible Securities is subsequently increased, then the Effective Price shall
again be recalculated using the increased minimum amount of consideration
payable to the corporation upon the exercise of such Rights or Options or the
conversion or exchange of such Convertible Securities.

     No further adjustment of the Conversion Price, adjusted upon the issuance
of such Rights or Options or Convertible Securities, shall be made as a result
of the actual issuance of shares of Common Stock on the exercise of any such
Rights or Options or the conversion or exchange of any such Convertible
Securities.  If any such Rights or Options or the conversion rights represented
by any such Convertible Securities shall expire without having been fully
exercised, then the Conversion Price as adjusted upon the issuance of such
Rights or Options or Convertible Securities shall be readjusted to the
Conversion Price which would have been in effect had an adjustment been made on
the basis that the only shares of Common Stock so issued were the shares of
Common Stock, if any, that were actually issued or sold on the exercise of such
Rights or Options or rights of conversion or exchange of such Convertible
Securities, and such shares of Common Stock, if any, were issued or sold for the
consideration actually received by the corporation upon such exercise, plus the
consideration, if any, actually received by the corporation for the granting of
all such Rights or Options, whether or not exercised, plus the consideration
received for issuing or selling all such Convertible Securities actually
converted or exchanged, plus the consideration, if any, actually received by the
corporation (other than by cancellation of liabilities or obligations evidenced
by such Convertible Securities) on the conversion or exchange of such
Convertible Securities, provided that such readjustment shall not apply to prior
conversions of Preferred Stock.

          (h)  Certificate of Adjustment.  In each case of an adjustment or
               -------------------------                                   
readjustment of the Conversion Price for a series of Preferred Stock, the
corporation, at its expense, shall cause its Chief Financial Officer to compute
such adjustment or readjustment in accordance with the provisions hereof and
prepare a certificate showing such adjustment or readjustment, and shall mail
such certificate, by first class mail, postage prepaid, to each registered
holder of the Preferred Stock at the holder's address as shown in the
corporation's books.

          (i)  Fractional Shares.  No fractional shares of Common Stock shall be
               -----------------                                                
issued upon any conversion of Preferred Stock.  In lieu of any fractional share
to which the holder would otherwise be entitled, the corporation shall pay the
holder cash equal to the product of such fraction multiplied by the Common
Stock's fair market value as determined in good faith by the Board as of the
date of conversion.

          (j)  Notices.  Any notice required by the provisions of this Section 5
               -------          
to be given to the holders of Preferred Stock shall be deemed given if deposited
in the United States mail, postage prepaid, and addressed to each holder of
record at such holder's address appearing on the books of the corporation.

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

          (i)  At any time following the Purchase Date of the Series A Preferred
Stock, if (a) the holders of shares of Series A Preferred Stock are entitled to

                     (1) in the case of an issuance of Series A1 Preferred
Stock, (i) to cancel all authorized shares of Series A1 Preferred Stock that
remain unissued after such issuance (other than any such shares reserved for
issuance upon exercise of then outstanding warrants for such shares), and (ii)
to create and reserve for issuance upon Special Mandatory Conversion of any
Series A Preferred Stock a new series of Preferred Stock equal in number to the
number of shares of Series A1 Preferred Stock so canceled and designated Series
A2 Preferred Stock with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series A1 Preferred Stock, except that the Conversion Price for such
shares of Series A2 Preferred Stock once initially issued shall be the Series A
Conversion Price in effect immediately prior to such issuance;

                     (2) in the case of an issuance of Series B1 Preferred
Stock, (i) to cancel all authorized shares of Series B1 Preferred Stock that
remain unissued after such issuance (other than any such shares reserved for
issuance upon exercise of outstanding warrants to purchase such shares), and
(ii) to create and reserve for issuance upon Special Mandatory Conversion of any
Series B Preferred Stock a new series of Preferred Stock equal in number to the
number of shares of Series B1 Preferred Stock so canceled and designated Series
B2 Preferred Stock with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series B1 Preferred Stock, except that the Conversion Price for such
shares of Series B2 Preferred Stock once initially issued shall be the Series B
Conversion Price in effect immediately prior to such issuance;

                     (3) in the case of an issuance of Series C1 Preferred
Stock, (i) to cancel all authorized shares of Series C1 Preferred Stock that
remain unissued after such issuance (other than any such shares reserved for

(ii) to create and reserve for issuance upon Special Mandatory

Conversion of any Series C Preferred Stock a new series of Preferred Stock equal
in number to the number of shares of Series C1 Preferred Stock so canceled and
designated Series C2 Preferred Stock with the designations, powers, preferences
and rights and the qualifications, limitations and restrictions identical to
those then applicable to the Series C1 Preferred Stock, except that the
Conversion Price for such shares of Series C2 Preferred Stock once initially
issued shall be the Series C Conversion Price in effect immediately prior to
such issuance;

                     (4) in the case of an issuance of Series D1 Preferred
Stock, (i) to cancel all authorized shares of Series D1 Preferred Stock that
remain unissued after such issuance (other than any such shares reserved for
issuance upon exercise of outstanding warrants to purchase such shares), and
(ii) to create and reserve for issuance upon Special Mandatory Conversion of any
Series D Preferred Stock a new series of Preferred Stock equal in number to the
number of shares of Series D1 Preferred Stock so canceled and designated Series
D2 Preferred Stock with the designations, powers, preferences and rights and the
qualifications, limitations and restrictions identical to those then applicable
to the Series D1 Preferred Stock, except that the Conversion Price for such
shares of Series D2 Preferred Stock once initially issued shall be the Series D
Conversion Price in effect immediately prior to such issuance;

                     (5) to amend the provisions of this subsection 5(k) to
provide that any subsequent Special Mandatory Conversion of the Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock
and/or the Series D Preferred Stock will be into shares of Series A2, Series B2,
Series C2 or Series D2 Preferred Stock, respectively, rather than Series A1,
Series B1, Series C1 or Series D1 Preferred Stock.

     The corporation shall take the same actions with respect to the Series A2,
Series B2 and Series C2 Preferred Stock and each subsequently authorized series
of Preferred Stock upon initial issuance of shares of the last such series to be
authorized.  The right to receive any dividend declared but unpaid at the time
of conversion on any shares of Preferred Stock converted pursuant to the
provisions of this subsection 5(k) shall accrue to the benefit of the new shares
of Preferred Stock issued upon conversion thereof.

     6.   Voting Rights.  The holder of each share of Preferred Stock shall have
          -------------                                                    
the right to one vote for each share of Common Stock into which such Preferred
Stock could then be converted, and with respect to such vote, such holder shall
have full voting rights and powers equal to the voting rights and powers of the
holders of Common Stock, and shall be entitled, notwithstanding any provision
hereof, to notice of any shareholders' meeting in accordance with the Bylaws of
the corporation, and shall be entitled to vote, together with holders of Common
Stock, with respect to any question upon which holders of Common Stock have the
right to vote. Fractional votes shall not, however, be permitted and any
fractional voting rights available on an as-converted basis (after aggregating
all shares into which shares of Preferred Stock held by each holder could be
converted) shall be rounded to the nearest whole number (with one-half being
rounded upward).

     7.   Protective Provisions.  So long as any shares of any series of
          ---------------------                  
Preferred Stock are outstanding, the corporation shall not without first
obtaining the approval (by vote or written consent, as provided by law) of
holders of at least seventy-five percent (75%) of the outstanding shares of
Preferred Stock voting together as a single class, on an as-converted basis
except for subsection (c) hereof which shall require the approval (by vote or
written consent, as provided by

                                       17

law) of holders of at least sixty-six and two-thirds percent (66 2/3%) of the
outstanding shares of Preferred Stock voting together as a single class, on an
as converted basis:

          (a)  sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other corporation (other than a wholly-owned subsidiary corporation) or
effect any transaction or series of related transactions in which more than
fifty percent (50%) of the voting power of the corporation is disposed of;

          (b)  increase or decrease (other than by redemption or conversion) the
total number of authorized shares of any series of Preferred Stock;

          (c)  enter into any agreement to voluntarily liquidate, dissolve or
wind up the corporation or take any action intended to effectuate any of the
foregoing;

          (d)  authorize the issuance of any other equity security, including
any other security convertible into or exercisable for any equity security (i)
having a preference over, or being on a parity with, any series of Preferred
Stock with respect to voting, dividends or upon liquidation, or (ii) having
rights similar to any of the rights of the Preferred Stock under this Section 7;

          (e)  alter or change the rights, preferences or privileges of the
shares of any series of Preferred Stock so as to affect adversely such shares;

          (f)  declare or pay any dividends or make other distributions on, or
redeem, purchase or acquire any Common Stock or any other class of capital stock
of the corporation except for redemptions made in accordance with the provisions
of Article III(c)(3) hereof and except for the repurchase of any Common Stock
pursuant to a repurchase right with respect to terminated employees;

          (g)  enter into any transaction or series of transactions for a value
greater than $50,000 with any affiliated person or entity (other than
transactions which have been approved by a majority of the disinterested
directors and the terms of which are comparable to transactions entered into on
an arm's length basis);

          (h)  amend the corporation's Certificate of Incorporation or Bylaws;

          (i)  acquire all or substantially all of the assets or capital stock
or securities of, or otherwise combine with any corporation, partnership or
other business entity or form a subsidiary for such purpose; or

          (j)  do any act or thing which would result in taxation of the holders
of shares of Preferred Stock under Section 305 of the Internal Revenue Code of
1986, as amended (or any comparable provision of the Internal Revenue Code as
hereafter amended from time to time).

     7.   Repurchase of Shares.  In connection with repurchases by the 
          --------------------                            
corporation of its Common Stock pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law,
to the extent applicable, shall not apply in whole or in part with respect to
such repurchases.

     The address of the registered office of the corporation in the State of

The name of its registered agent at that address is Corporation Service Company.

                                  ARTICLE III

     The total number of shares of all classes of stock which the corporation

                                           Restated Certificate of Incorporation

any series of Preferred Stock pursuant to the foregoing provisions of this
Article IV, any new series of Preferred Stock may be designated, fixed and
determined as provided herein by the Board of Directors without approval of the
holders of Common Stock or the holders of Preferred Stock, or any series
thereof, and any such new series may have powers, preferences and rights,
including, without limitation, voting rights, dividend rights, liquidation
rights, redemption rights and conversion rights senior to, junior to or pari
passu with the rights of the Common Stock, the Preferred Stock, or any future
class or series of Preferred Stock or Common Stock.

     If the certificate of designation creating a series of Preferred Stock so
provides, any shares of a series of Preferred Stock that are acquired by the
corporation, whether by redemption, purchase, conversion or otherwise, so that
such shares are issued but not outstanding, may not be reissued as shares of
such series or as shares of the class of Preferred Stock.  Upon the retirement
of any such shares and the filing of a certificate of retirement pursuant to
Sections 103 and 243 of the Delaware General Corporation Law with respect
thereto, the shares of such series shall be eliminated and the number of shares
of Preferred Stock shall be reduced accordingly.

from time to time exclusively by a resolution of the Board of Directors adopted
by the affirmative vote of a majority of the total number of directors that the
corporation would have if there were no vacancies.

     Any vacancy on the Board of Directors, however resulting, and any newly
created directorships resulting from any increase in the authorized number of
directors shall be filled only by the affirmative vote of a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director, unless the Board of Directors determines that any such vacancies or
newly created directorships shall be filled by the stockholders.

     The Board of Directors of the corporation shall have the power to adopt,
amend or repeal Bylaws of the corporation.

                                  ARTICLE VI

     Any action required or permitted to be taken by the stockholders of the
corporation may be  effected at a duly called annual or special meeting of such
holders and may not be effected by any consent in writing by such holders.
Subject to the rights of the holders of any class or series of Preferred Stock,
special meetings of stockholders of the corporation shall be called only by the
Board of Directors or upon the request of the Chairman of the Board of Directors
or the Chief Executive Officer of the corporation.  If a special meeting is
requested by the Chairman of the Board of Directors or the Chief Executive

the corporation shall so provide.

                                  ARTICLE VII
                                        
     To the fullest extent permitted by law, no director of the corporation
shall be personally liable for monetary damages for breach of fiduciary duty as
a director. Without limiting the effect of the preceding sentence, if the
Delaware General Corporation Law is hereafter amended to authorize the further
elimination or limitation of the liability of a director, then the liability of
a director of the corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

     Neither any amendment nor repeal of this Article VII, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article VII, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

special meetings of stockholders, and the corporation's stockholders may not act
by written consent.

                                    OFFICES

     Section 1.1:  Principal Office.  The principal executive office for the
     -----------   ----------------                                         
transaction of the business of this corporation (the "Company") shall be located
                                                      -------                   
at such place as the Board of Directors may from time to time decide.  The Board
of Directors is hereby granted full power and authority to change the location
of the principal executive office from one location to another.

     Section 1.2:  Other Offices.  One or more branch or other subordinate
     -----------   -------------

place or places within or outside the State of California as it deems

                                   DIRECTORS

     Section 2.1:  Exercise of Corporate  Powers.  Except as otherwise provided
     -----------   -----------------------------                               
by these Bylaws, by the Articles of Incorporation of the Company or by the laws
of the State
<PAGE>
 
of California now or hereafter in force, the business and affairs of the Company
shall be managed and all corporate powers shall be exercised by or under the
ultimate direction of a board of directors (the "Board of Directors").
                                                 ------------------   

     Section 2.2:  Number.  The authorized number of directors of this
     -----------   ------                                             
corporation shall be nine (9).  Any amendment to these Bylaws reducing the
minumum or fixed number of the authorized directors to a number less than five
(5) cannot be adopted if the votes cast against its adoption at a meeting, or
the shares not consenting in the case of action by written consent, are equal to
more than 16-2/3% of the outstanding shares entitled to vote.

     Section 2.3:  Need Not Be Shareholders.  The directors of the Company need
     -----------   ------------------------                                    
not be shareholders of this Company.

     Section 2.4:  Compensation.  Directors and members of committees may
     -----------   ------------                                          
receive such compensation, if any, for their services as may be fixed or
determined by resolution of the Board of Directors.  Nothing herein contained
shall be construed to preclude any director from serving the Company in any
other capacity and receiving compensation therefor.

     Section 2.5:  Election and Term of Office.  The directors shall be elected
     -----------   ---------------------------                                 
annually by the shareholders at the annual meeting of the shareholders.  The
term of office of the directors shall begin immediately after their election and
shall continue until the next annual meeting of the shareholders and until their
respective successors are elected.  A reduction of the authorized number of
directors shall not shorten the term of any incumbent director or remove any
incumbent director prior to the expiration of such director's term of office.

     Section 2.6:  Vacancies.  A vacancy or vacancies on the Board of Directors
     -----------   ---------                                                   
shall exist:

     (a) in the case of the death of any director; or

     (b) in the case of the resignation or removal of any director; or

     (c) if the authorized number of directors is increased; or

     (d) if the shareholders fail, at any annual meeting of shareholders at
which any director is elected, to elect the full authorized number of directors
at that meeting.

                                       2
<PAGE>
 
The Board of Directors may declare vacant the office of a director if he or she
is declared of unsound mind by an order of court or convicted of a felony or if,
within 60 days after notice of his or her election, he or she does not accept
the office.  Any vacancy, except for a vacancy created by removal of a director
as provided in Section 2.7 hereof, may be filled by a person selected by a
majority of the remaining directors then in office, whether or not less than a
quorum, or by a sole remaining director.  Vacancies occurring in the Board of
Directors by reason of removal of directors shall be filled only by approval of
shareholders.  The shareholders may elect a director at any time to fill any
vacancy not filled by the directors.  Any such election by the written consent
of shareholders, other than to fill a vacancy created by removal, requires the
consent of shareholders holding a majority of the outstanding shares entitled to
vote.  If, after the filling of any vacancy by the directors, the directors then
in office who have been elected by the shareholders shall constitute less than a
majority of the directors then in office, any holder or holders of an aggregate
of 5% or more of the total number of shares at that time having the right to
vote for such directors may call a special meeting of shareholders to be held to
elect the entire Board of Directors.  The term of office of any director then in
office shall terminate upon the election of such director's successor.  Any
director may resign effective upon giving written notice to the Chairman of the
Board, if any, the President, the Secretary or the Board of Directors, unless
the notice specifies a later time for the effectiveness of such resignation.
After the notice is given and if the resignation is effective at a future time,
a successor may be elected or appointed to take office when the resignation
becomes effective.

     Section 2.7:  Removal.  The entire Board of Directors or any individual
     -----------   -------                                                  
director may be removed from office without cause by an affirmative vote of
shareholders holding a majority of the outstanding shares entitled to vote.  If
the entire Board of Directors is not removed, however, then no individual
director shall be removed if the votes cast against removal of that director,
plus the votes not consenting in writing to such removal, would be sufficient to
elect that director if voted cumulatively in an election at which the following
were true:

     (a) the same total number of votes were cast, or, if such action is taken
by written consent, all shares entitled to vote were voted; and

     (b) the entire number of directors authorized at the time of the director's
most recent election were then being elected.

If any or all directors are so removed, new directors may be elected at the same
meeting or at a subsequent meeting.  If at any time a class or series of shares
is entitled to elect one or more directors under authority granted by the
Articles of Incorporation, the provisions of this Section 2.7 shall apply to the
vote of that class or series and not to the vote of the outstanding shares as a
whole.

     Section 2.8:  Powers and Duties.  Without limiting the generality or extent
     -----------   -----------------                                            
of the general corporate powers to be exercised by the Board of Directors
pursuant to Section

less than 10 days prior to the date of the meeting nor more than 60 days prior
to any other

                                       4

action for which it is fixed, as a record date for the determination of the
shareholders entitled to notice of and to vote at any meeting, or entitled to
receive any payment of any dividend or other distribution, or allotment of any
rights, or entitled to exercise any rights in respect of any other lawful
action; and in such case only shareholders of record on the date so fixed shall
be entitled to notice of and to vote at the meeting or to receive the dividend,
distribution or allotment of rights or to exercise the rights, as the case may
be, notwithstanding any transfer of any shares on the books of the Company after
any record date fixed as aforesaid.  The Board of Directors may close the books
of the Company against transfers of shares during the whole or any part of such
period.

     (l) To fix and locate from time to time the principal office for the

mortgages, pledges (or other transfers of property as security or collateral for
a debt), or other evidences of debt and securities therefor; and the note or
other obligation given for any indebtedness of the Company, signed officially by
any officer or officers thereunto duly authorized by the Board of Directors,
shall be binding on the Company.

     (p) To approve a loan of money or property to any officer or director of
the Company or any parent or subsidiary company, guarantee the obligation of any
such officer or director, or approve an employee benefit plan authorizing such a
loan or guaranty to any such officer or director; provided that, on the date of

resolution of the Board of Directors.  Notice of the time and place of all

Every act or decision done or made by a majority of the directors present at a

all members of the Board of Directors shall individually or collectively consent
in writing to the taking of such action.  Such written consent or consents shall

     -----------   ---------------------------------                          
meeting of shareholders, however called and noticed, and wherever held, are as
valid as though they had taken place at a meeting duly held after regular call
and notice, if the following conditions are met:

     (a)  a quorum is present, either in person or by proxy, and

     (b)  either before or after the meeting, each of the shareholders entitled
to vote, who was not present in person or by proxy, signs a written waiver of
notice or a consent to the holding of such meeting or an approval of the minutes
thereof.  All such waivers, consents or approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

Attendance of a person at a meeting shall constitute both a waiver of notice of
and presence at such meeting, except:  (a) when the person objects, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened; or (b) when the person expressly makes an
objection at some time during the meeting to the consideration of matters
required by law to be included in the notice but not so included.

Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of shareholders need be specified in any written waiver of
notice, consent to the holding of the meeting or approval of the minutes
thereof, except as to approval of contracts between the Company and any of its
directors, amendment of the Articles of Incorporation, reorganization of the
Company or winding up the affairs of the Company.

     Section 7.6:  Quorum.  The presence in person or by proxy of the holders of
     -----------   ------                                                       
a majority of the shares entitled to vote at any meeting of the shareholders
shall constitute a quorum for the transaction of business.  Shares shall not be
counted to make up a quorum for a meeting if voting of such shares at the
meeting has been enjoined or for any reason they cannot be lawfully voted at the
meeting.  Shareholders present at a duly called or held meeting at which a
quorum is present may continue to transact business until adjournment
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum, if any action taken (other than adjournment) is approved by at least a
majority of the shares required to constitute a quorum.  Except as provided
herein, the affirmative vote of a majority of the shares represented and voting
at a duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or voting by
classes is required.

     Section 7.7:  Adjourned Meetings.  Any shareholders' meeting, whether or
     -----------   ------------------                                        
not a quorum is present, may be adjourned from time to time by the vote of a
majority of the shares, the holders of which are either present in person or
represented by proxy thereat, but, except as provided in Section 7.6 hereof, in
the absence of a quorum, no other

                                      16
<PAGE>
 
business may be transacted at such meeting.  When a meeting is adjourned for
more than 45 days or if after adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
shareholder of record entitled to vote at a meeting.  Except as aforesaid, it
shall not be necessary to give any notice of the time and place of the adjourned
meeting or of the business to be transacted thereat other than by announcement
at the meeting at which such adjournment is taken.  At any adjourned meeting the
shareholders may transact any business which might have been transacted at the
original meeting.

     Section 7.8:  Voting Rights.  Only persons in whose names shares entitled
     -----------   -------------                                              
to vote stand on the stock records of the Company at:

     (a)  the close of business on the business day immediately preceding the
day on which notice is given; or

     (b)  if notice is waived, at the close of business on the business day
immediately preceding the day on which the meeting is held; or

     (c)  if some other day be fixed for the determination of shareholders of
record pursuant to Section 2.8(k) hereof, then on such other day, shall be
entitled to vote at such meeting.

The record date for determining shareholders entitled to give consent to
corporate action in writing without a meeting, when no prior action by the Board
of Directors has been taken, shall be the day on which the first written consent
is given.  In the absence of any contrary provision in the Articles of
Incorporation or in any applicable statute relating to the election of directors
or to other particular matters, each such person shall be entitled to one vote
for each share.

     Section 7.9:  Action by Written Consents.  Any action which may be taken at
     -----------   --------------------------                                   
any annual or special meeting of shareholders may be taken without a meeting and
without prior notice, if a consent in writing, setting forth the action so
taken, shall be signed by holders of outstanding shares having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.  Unless the consents of all shareholders entitled to vote have been
solicited in writing, the Company shall provide notice of any shareholder
approval obtained without a meeting by less than unanimous written consent to
those shareholders entitled to vote but who have not yet consented in writing at
least 10 days before the consummation of the following actions authorized by
such approval:  (a) contracts between the Company and any of its directors; (b)
indemnification of any person; (c) reorganization of the Company; or (d)
distributions to shareholders upon the winding-up of the affairs of the Company.
In addition, the Company shall provide, to those shareholders entitled to vote
who have not consented in writing, prompt notice of the taking of any other
corporate action approved by the shareholders without a meeting by less than
unanimous written consent.  All notices

                                      17
<PAGE>
 
given hereunder shall conform to the requirements of Section 7.4 hereto and
applicable law.  When written consents are given with respect to any shares,
they shall be given by and accepted from the persons in whose names such shares
stand on the books of the Company at the time such respective consents are
given, or their proxies.  Any shareholder giving a written consent (including
any shareholder's proxy holder, or a transferee of the shares or a personal
representative of the shareholder, or their respective proxy holders) may revoke
the consent by a writing.  This writing must be received by the Company prior to
the time that written consents of the number of shares required to authorize the
proposed action have been filed with the Secretary of the Company.  Such
revocation is effective upon its receipt by the Secretary of the Company.
Notwithstanding anything herein to the contrary, and subject to Section 305(b)
of the California Corporations Code, directors may not be elected by written
consent except by unanimous written consent of all shares entitled to vote for
the election of directors.

     Section 7.10:  Election of Directors.  Every shareholder entitled to vote
     ------------   ---------------------                                     
at any election of directors of the Company may cumulate such shareholder's
votes and give one candidate a number of votes equal to the number of directors
to be elected multiplied by the number of votes to which the shareholder's
shares are normally entitled, or distribute the shareholder's votes on the same
principle among as many candidates as such shareholder thinks fit.  No
shareholder, however, may cumulate such shareholder's votes for one or more
candidates unless such candidate's or candidates' names have been placed in
nomination prior to the voting and the shareholder has given notice at the
meeting, prior to voting, of such shareholder's intention to cumulate such
shareholder's votes.  If any one shareholder has given such notice, all
shareholders may cumulate their votes for candidates in nomination.  The
candidates receiving the highest number of affirmative votes of the shares
entitled to be voted for them up to the number of directors to be elected by
such shares shall be declared elected.  Votes against the director and votes
withheld shall have no legal effect.  Election of directors need not be by
ballot except upon demand made by a shareholder at the meeting and before the
voting begins.

     Section 7.11:  Proxies.  Every person entitled to vote or execute consents
     ------------   -------                                                    
shall have the right to do so either in person or by one or more agents
authorized by a written proxy executed by such person or such person's duly
authorized agent and filed with the Secretary of the Company.  No proxy shall be
valid (a) after revocation thereof, unless the proxy is specifically made
irrevocable and otherwise conforms to this Section and applicable law, or (b)
after the expiration of eleven months from the date thereof, unless the person
executing it specifies therein the length of time for which such proxy is to
continue in force.  Revocation may be effected by a writing delivered to the
Secretary of the Company stating that the proxy is revoked or by a subsequent
proxy executed by the person executing the prior proxy and presented to the
meeting, or as to any meeting by attendance at the meeting and voting in person
by the person executing the proxy.  A proxy is not revoked by the death or
incapacity of the maker unless, before the vote is counted, a written notice of
such death or incapacity is received by the Secretary of the Company.  In
addition, a proxy may be revoked, notwithstanding a provision making it
irrevocable, by a transferee of shares without knowledge of the existence of the
provision

                                      18
<PAGE>
 
unless the existence of the proxy and its irrevocability appears on the
certificate representing such shares.

     Section 7.12:  Inspectors of Election.  Before any meeting of shareholders,
     ------------   ----------------------                                      
the Board of Directors may appoint any persons other than nominees for office as
inspectors of election.  This appointment shall be valid at the meeting and at
any subsequent meeting that is a continuation of the meeting at which the
persons were originally appointed to be inspectors.  If no inspectors of
election are so appointed, the Chairman of the meeting may, and on the request
of any shareholder or a shareholder's proxy shall, appoint inspectors of
election at the meeting.  The number of inspectors shall be either one or three.
If inspectors are appointed at a meeting on the request of one or more
shareholders or proxies, the holders of a majority of shares or their proxies
present at the meeting shall determine whether one or three inspectors are to be
appointed.  If any person appointed as inspector fails to appear or fails or
refuses to act, the Chairman of the meeting may, and upon the request of any
shareholder or a shareholder's proxy shall, appoint a person to fill that
vacancy.  These inspectors shall:

     (a)  determine the number of shares outstanding and the voting power of
each, the shares represented at the meeting, the existence of a quorum, and the
authenticity, validity, and effect of proxies;

     (b)  receive votes, ballots, or consents;

     (c)  hear and determine all challenges and questions in any way arising in
connection with the right to vote;

     (d)  count and tabulate all votes or consents;

     (e)  determine when the polls shall close;

     (f)  determine the result; and

     (g)  do any other acts that may be proper to conduct the election or vote
with fairness to all shareholders.

     Section 7.13:  Annual Reports.  Provided that the Company has 100 or fewer
     ------------   --------------                                             
shareholders, the making of annual reports to the shareholders is dispensed with
and the requirement that such annual reports be made to shareholders is
expressly waived, except as may be directed from time to time by the Board of
Directors or the President.

                         SHARES AND SHARE CERTIFICATES

     Section 8.1:  Shares Held By the Company.  Shares in other companies
     -----------   --------------------------                            
standing in the name of the Company may be voted or represented and all rights
incident thereto may be exercised on behalf of the Company by any officer of the
Company authorized to do so by resolution of the Board of Directors.

     Section 8.2:  Certificates for Shares.  There shall be issued to every
     -----------   -----------------------                                 
holder of shares in the Company a certificate or certificates signed in the name
of the Company by the Chairman of the Board, if any, or the President or a Vice
President and by the Chief Financial Officer or an Assistant Chief Financial
Officer or the Secretary or any Assistant Secretary, certifying the number of
shares and the class or series of shares owned by the shareholder.  Any or all
of the signatures on the certificate may be facsimile.  In case any officer,
transfer agent or registrar who has signed or whose facsimile signature has been
placed upon a certificate shall have ceased to be such officer, transfer agent
or registrar before such certificate is issued, it may be issued by the Company
with the same effect as if such person were an officer, transfer agent or
registrar at the date of issue.

     Section 8.3:  Lost Certificates.  Where the owner of any certificate for
     -----------   -----------------                                         
shares of the Company claims that the certificate has been lost, stolen or
destroyed, a new certificate shall be issued in place of the original
certificate if the owner (a) so requests before the Company has notice that the
original certificate has been acquired by a bona fide purchaser and (b)
satisfies any reasonable requirements imposed by the Company, including without
limitation the filing with the Company of an indemnity bond or agreement in such
form and in such amount as shall be required by the President or a Vice
President of the Company.  The Board of Directors may adopt such other
provisions and restrictions with reference to lost certificates, not
inconsistent with applicable law, as it shall in its discretion deem
appropriate.

     Section 8.4:  Restrictions on Transfer of Shares.
     -----------   ---------------------------------- 

     (a)  Before any shareholder of the Company may sell, assign, gift, pledge
or otherwise transfer any shares of the Company's capital stock, such
shareholder shall first notify the Company in writing of such transfer and such
transfer may not be effected unless and until legal counsel for the Company has
concluded that such transfer, when effected as proposed by such shareholder (i)
will comply with all applicable provisions of any applicable state and federal
securities laws, including but not limited to the Securities Act of 1933, as
amended, and the California Corporate Securities Law of 1968, as amended, and
(ii) will not jeopardize, terminate or adversely affect the Company's status as
an S Corporation, if applicable, as that term is defined in the Internal Revenue
Code of 1986, as amended. The Company may require that certificates representing
shares of stock of the Company be endorsed with a legend describing the
restrictions set forth in this Section.

                                      20
<PAGE>
 
     (b)  If (i) any two or more shareholders of the Company shall enter into
any agreement abridging, limiting or restricting the rights of any one or more
of them to sell, assign, transfer, mortgage, pledge, hypothecate or transfer on
the books of the Company any or all of the shares of the Company held by them,
and if a copy of said agreement shall be filed with the Company, or if (ii)
shareholders entitled to vote shall adopt any Bylaw provision abridging,
limiting or restricting the rights of any shareholders mentioned above, then,
and in either of such events, all certificates of shares of stock subject to
such abridgments, limitations or restrictions shall have a reference thereto
endorsed thereon by an officer of the Company and such certificates shall not
thereafter be transferred on the books of the Company except in accordance with
the terms and provisions of such as the case may be; however, no restriction
shall be binding with respect to shares issued prior to adoption of the
restriction unless the holders of such shares voted in favor of, or consented in
writing to, the restriction.

phrase of these Bylaws which, upon being construed in the manner provided in
Section 9.1 hereof, shall be contrary to or inconsistent with any applicable
provision of law, shall not apply so long as said provisions of law shall remain
in effect, but such result shall not affect the validity or applicability of any
other portion of these Bylaws, it being hereby declared that these Bylaws, and
each article, section, subsection, subdivision, sentence, clause or phrase
thereof, would have been adopted irrespective of the fact that any one or more
articles, sections, subsections, subdivisions, sentences, clauses or phrases is
or are illegal.

            CERTIFICATION, ADOPTION, AMENDMENT OR REPEAL OF BYLAWS

     Section 10.1: By Shareholders.  Bylaws may be adopted, amended or repealed

by the vote or written consent of holders of a majority of the outstanding
shares entitled to vote.  Bylaws specifying or changing a fixed number of
directors or the maximum or minimum number or changing from a fixed to a
variable board or vice versa may be adopted only by the shareholders.

     Section 10.2: By the Board of Directors.  Subject to the right of
     ------------  -------------------------                          
shareholders to adopt, amend or repeal Bylaws, and other than a Bylaw or
amendment thereof specifying or changing a fixed number of directors or the
maximum or minimum number or changing from a fixed to a variable board or vice
versa, these Bylaws may be adopted, amended or repealed by the Board of
Directors.  A Bylaw adopted by the shareholders may restrict or eliminate the
power of the Board of Directors to adopt, amend or repeal Bylaws.

amended or otherwise altered to date, which shall be open to inspection by the
shareholders at all reasonable times during office hours.

                          As Adopted January 15, 1998

     Section 1.1:  Annual Meetings.  An annual meeting of stockholders shall be
     -----------   ---------------                                             
held for the election of directors at such date, time and place, either within
or without the State of Delaware, as the Board of Directors shall each year fix.
Any other proper business may be transacted at the annual meeting.

     -----------   ----------------                                           
purpose or purposes may be called at any time by the Chairman of the Board, the

                                                          -----------
Shareholders") or by a majority of the members of the Board of Directors.
- ------------                                                              
Special meetings may not be called by any other person or persons.  If a special
meeting of stockholders is called by any person or persons other than by a
                                                           ----- ----     
majority of the members of the Board of Directors, then such person or persons
shall call such meeting by delivering a written request to call such meeting to
each member of the Board of Directors, and the Board of Directors shall then
determine the time, date and place of such special meeting, which shall be held
not more than one hundred twenty (120) nor less than thirty-five (35) days after
the written request to call such special meeting was delivered to each member of
the Board of Directors.  Effective immediately after the closing of an
underwritten public offering of shares of the Corporation's Common Stock
pursuant to a registration statement filed with and declared effective by the

Special Meeting of Stockholders.

     Section 1.3:  Notice of Meetings.  Written notice of all meetings of
     -----------   ------------------

Incorporation of the Corporation, such notice shall be given not less than ten
(10) nor more than sixty (60) days before the date of the meeting to each
stockholder entitled to vote at such meeting.

     Section 1.4:  Adjournments.  Any meeting of stockholders may adjourn from
     -----------   ------------                                               
time to time to reconvene at the same or another place, and notice need not be
given of any such adjourned meeting if the time, date and place thereof are
announced at the meeting at which the adjournment is taken; provided, however,
                                                            --------  ------- 
that if the adjournment is for more than thirty (30) days, or if after the
adjournment, a new record date is fixed for the adjourned meeting, then a notice
of the adjourned meeting shall be given to each stockholder of record entitled
to vote at the meeting.  At the adjourned meeting, the Corporation may transact
any business that might have been transacted at the original meeting.

     Section 1.5:  Quorum.  At each meeting of stockholders, the holders of a
     ------------  ------    
 majority of the shares of stock entitled to vote at the meeting, present in
person or represented by proxy, shall constitute a quorum for the transaction of
business, except if otherwise required by applicable law.  If a quorum shall
          ------                                                            
fail to attend any meeting, the chairman of the meeting or the holders of a
majority of the shares entitled to vote who are present, in person or by proxy,
at the meeting may adjourn the meeting.  Shares of the Corporation's stock
belonging to the Corporation (or to another corporation, if a majority of the
shares entitled to vote in the election of directors of such other corporation
are held, directly or indirectly, by the Corporation), shall neither be entitled
to vote nor be counted for quorum purposes; provided, however, that the
                                            --------  -------          
foregoing shall not limit the right of the Corporation or any other corporation
to vote any shares of the Corporation's stock held by it in a fiduciary
capacity.

     Section 1.6:  Organization. Meetings of stockholders shall be presided over
     ------------  ------------
by such person as the Board of Directors may designate, or, in the absence of
such a person, the Chairman of the Board, or, in the absence of such person, the
President of the Corporation, or, in the absence of such person, such person as
may be chosen by the holders of a majority of the shares entitled to vote who
are present, in person or by proxy, at the meeting. Such person shall be
chairman of the meeting and, subject to Section 1.11 hereof, shall determine the
order of business and the procedure at the meeting, including such regulation of
the manner of voting and the conduct of discussion as seems to him or her to be
in order. The Secretary of the Corporation shall act as secretary of the
meeting, but in his or her absence, the chairman of the meeting may appoint any
person to act as secretary of the meeting.

     Section 1.7:  Voting; Proxies.  Unless otherwise provided by law or the
     -----------   --------------- 
Certificate of Incorporation, and subject to the provisions of Section 1.8 of
these Bylaws, each stockholder shall be entitled to one (1) vote for each share
of stock held by such stockholder. Each stockholder entitled to vote at a
meeting of stockholders, or to express consent or dissent to corporate action in
writing without a meeting, may authorize another person or persons to act for
such stockholder by proxy. Such a proxy may be prepared, transmitted and
delivered in any manner permitted by applicable law. Voting at meetings of
stockholders need not be by written ballot unless such is demanded at the
meeting before voting begins by a stockholder or stockholders holding shares
representing at least one percent (1%) of the votes entitled to vote at such
meeting, or by such stockholder's or stockholders' proxy; provided, however,
                                                          --------  -------
that an election of directors shall be by written ballot if demand is so made by
any stockholder at the meeting before voting begins. If a vote is to be taken by
written ballot, then each such ballot shall state the name of the stockholder or
proxy voting and such other information as the

                                      -2-
<PAGE>
 
chairman of the meeting deems appropriate.  Directors shall be elected by a
plurality of the votes of the shares present in person or represented by proxy
at the meeting and entitled to vote on the election of directors.  Unless
otherwise provided by applicable law, the Certificate of Incorporation or these
Bylaws, every matter other than the election of directors shall be decided by
the affirmative vote of the holders of a majority of the shares of stock
entitled to vote thereon that are present in person or represented by proxy at
the meeting and are voted for or against the matter.

     Section 1.8:  Fixing Date for Determination of Stockholders of Record.
     -----------   ------------------------------------------------------- 

     (a)  Generally. In order that the Corporation may determine the
          ---------
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not precede the date upon which the resolution fixing the record
date is adopted by the Board of Directors and which shall not be more than sixty
(60) nor less than ten (10) days before the date of such meeting, nor more than
sixty (60) days prior to any other action. If no record date is fixed by the
Board of Directors, then the record date shall be as provided by applicable law.
A determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
                                                                       --------
however, that the Board of Directors may fix a new record date for the adjourned
- ------- 
meeting.

     (b)  Stockholder Request for Action by Written Consent.  For such period of
          -------------------------------------------------
time as stockholders are authorized to act by written consent pursuant to the
provisions of the Certificate of Incorporation and Section 1.10 hereof, any
stockholder of record seeking to have the stockholders authorize or take
corporate action by written consent without a meeting shall, by written notice
to the Secretary of the Corporation, request the Board of Directors to fix a
record date for such consent. Such request shall include a brief description of
the action proposed to be taken. The Board of Directors shall, within ten (10)
days after the date on which such a request is received, adopt a resolution
fixing the record date. Such record date shall not precede the date upon which
the resolution fixing the record date is adopted by the Board of Directors, and
shall not be more than ten (10) days after the date upon which the resolution
fixing the record date is adopted by the Board of Directors. If no record date
has been fixed by the Board of Directors within ten (10) days after the date on
which such a request is received, then the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting, when no prior action by the Board of Directors is required by
applicable law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
Corporation by delivery to its registered office in the State of Delaware, to
its principal place of business or to any officer or agent of the Corporation
having custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to the Corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by applicable law, then the record date for determining

                                      -3-
<PAGE>
 
stockholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the date on which the Board of
Directors adopts the resolution taking such prior action.

     Section 1.9:   List of Stockholders Entitled to Vote. A complete list of
     -----------    -------------------------------------
stockholders entitled to vote at any meeting of stockholders, arranged in
alphabetical order and showing the address of each stockholder and the number of
shares registered in the name of each stockholder, shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any stockholder who is present at the meeting.

     Section 1.10:  Action by Written Consent of Stockholders.
     ------------   ----------------------------------------- 

     (a)  Procedure.  Unless otherwise provided by the Certificate of
          ---------
Incorporation, and except as set forth in Section 1.8(b) above, any action
required or permitted to be taken at any annual or special meeting of the
stockholders may be taken without a meeting, without prior notice and without a
vote, if a consent or consents in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted;
Provided, however, that effective immediately after the closing of an
- --------  -------                                                    
underwritten public offering of shares of the Corporation's Common Stock
pursuant to a registration statement filed with and declared effective by the
Securities and Exchange Commission, any action required or permitted to be taken
by the Corporation's stockholders shall be taken only at a duly called annual or
special meeting of such stockholders, and the Corporation's stockholders shall
not be able to act by written consent.  For such period of time as written
stockholder consents are permitted, such consents shall bear the date of
signature of each stockholder who signs the consent and shall be delivered to
the Corporation by delivery to its registered office in the State of Delaware,
to its principal place of business or to any officer or agent of the Corporation
having custody of the book in which proceedings of meetings of stockholders are
recorded.  Delivery made to the Corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested.  No written
consent shall be effective to take the action set forth therein unless, within
sixty (60) days of the earliest dated consent delivered to the Corporation in
the manner provided above, written consents signed by a sufficient number of
stockholders to take the action set forth therein are delivered to the
Corporation in the manner provided above.

     (b)  Notice of Consent.  Prompt notice of the taking of corporate action by
          -----------------
stockholders without a meeting by less than unanimous written consent of the
stockholders shall be given to those stockholders who have not consented thereto
in writing, and, in the case of a Certificate Action (as defined below), if the
Delaware General Corporation Law so requires, such notice shall be given prior
to filing of the certificate in question. If the action which is consented to
requires the filing of a certificate under the Delaware General Corporation Law
(a

                                      -4-
<PAGE>
 
"Certificate Action"), then if the Delaware General Corporation Law so requires,
 ------------------                                                             
the certificate so filed shall state that written stockholder consent has been
given in accordance with Section 228 of the Delaware General Corporation Law and
that written notice of the taking of corporate action by stockholders without a
meeting as described herein has been given as provided in such section.

     Section 1.11:    Inspectors of Elections.
     ------------     ----------------------- 

     (a)  Applicability. Unless otherwise provided in the Corporation's
          -------------
Certificate of Incorporation or required by the Delaware General Corporation
Law, the f ollowing provisions of this Section 1.11 shall apply only if and when
the Corporation has a class of voting stock that is: (i) listed on a national
securities exchange; (ii) authorized for quotation on an interdealer quotation
system of a registered national securities association; or (iii) held of record
by more than 2,000 stockholders; in all other cases, observance of the
provisions of this Section 1.11 shall be optional and at the discretion of the
Corporation.

    (b)   Appointment.  The Corporation shall, in advance of any meeting of
          -----------                                                      
stockholders, appoint one or more inspectors of election to act at the meeting
and make a written report thereof.  The Corporation may designate one or more
persons as alternate inspectors to replace any inspector who fails to act.  If
no inspector or alternate is able to act at a meeting of stockholders, the
person presiding at the meeting shall appoint one or more inspectors to act at
the meeting.

     (c)  Inspector's Oath. Each inspector of election, before entering upon the
          ----------------  
discharge of his duties, shall take and sign an oath faithfully to execute the
duties of inspector with strict impartiality and according to the best of his or
her ability.

     (d)  Duties of Inspectors. At a meeting of stockholders, the inspectors of
          --------------------
election shall (i) ascertain the number of shares outstanding and the voting
power of each share, (ii) determine the shares represented at a meeting and the
validity of proxies and ballots, (iii) count all votes and ballots, (iv)
determine and retain for a reasonable period of time a record of the disposition
of any challenges made to any determination by the inspectors and (v) certify
their determination of the number of shares represented at the meeting and their
count of all votes and ballots. The inspectors may appoint or retain other
persons or entities to assist the inspectors in the performance of the duties of
the inspectors.

     (e)  Opening and Closing of Polls.  The date and time of the opening and
          ----------------------------
the closing of the polls for each matter upon which the stockholders will vote
at a meeting shall be announced by the inspectors at the meeting. No ballot,
proxies or votes, nor any revocations thereof or changes thereto, shall be
accepted by the inspectors after the closing of the polls unless the Court of
Chancery upon application by a stockholder shall determine otherwise.

     (f)  Determinations. In determining the validity and counting of proxies
          --------------
and ballots, the inspectors shall be limited to an examination of the proxies,
any envelopes submitted with those proxies, any information provided in
connection with proxies in accordance with Section

                                      -5-
<PAGE>
 
212(c)(2) of the Delaware General Corporation Law, the ballots and the regular
books and records of the Corporation, except that the inspectors may consider
                                      ------                                 
other reliable information for the limited purpose of reconciling proxies and
ballots submitted by or on behalf of banks, brokers, their nominees or similar
persons that represent more votes than the holder of a proxy is authorized by
the record owner to cast or more votes than the stockholder holds of record.  If
the inspectors consider other reliable information for the limited purpose
permitted herein, the inspectors at the time they make their certification of
their determinations pursuant to this Section 1.11 shall specify the precise
information considered by them, including the person or persons from whom they
obtained the information, when the information was obtained, the means by which
the information was obtained and the basis for the inspectors' belief that such
information is accurate and reliable.

     Section 1.12:    Notice of Stockholder Business; Nominations.
     ------------     ------------------------------------------- 

     (a)  Annual Meeting of Stockholders.
          ------------------------------ 

          (i)    Nominations of persons for election to the Board of Directors

executive offices of the Corporation not later than the close of business on the
sixtieth (60th) day nor earlier than the close of business on the ninetieth
(90th) day prior to the first anniversary of the preceding year's annual

Securities issued upon conversion of the Series C Preferred Stock or any
securities issued upon conversion of the Series C Preferred Stock that the
Company file a registration statement under the 1933 Act for an aggregate
offering price, net of underwriting discounts and commissions, of at least
$7,500,000, then the Company shall:

                    (i)  within ten (10) days after the Company's receipt
thereof, give written notice of such request to all Holders; and

                    (ii) effect as soon as practicable, and in any event within

effected in accordance with Section 1.2 shall be (i) first, the securities the
Initiating Holders propose to sell on a pro rata basis, based upon the number of
Registrable Securities such Holders desire to include in such registration, (ii)

                                       4
<PAGE>
 
Registrable Securities (other than Excluded Shares) held by the Holders other
than the Initiating Holders on a pro rata basis, based upon the number of
Registrable Securities such Holders desire to include in such registration and
(iii) third, other securities, if any are requested to be included in such
registration, including Excluded Shares. In the event the Initiating Holders are
unable to include at least 50% of the Registrable Securities requested by them
to be included in a registration, such registration will not count as a
registration for purposes of Section 1.2(d); provided, however, that the
                                             --------  -------          
foregoing shall not be applicable in the event the Initiating Holders
nonetheless sell securities with an aggregate value of at least $7.5 million.

          (c)  Notwithstanding the foregoing, if the Company shall furnish to
the Holders requesting a registration statement pursuant to this Section 1.2, a
certificate signed by the Company (or, in connection with an underwritten
offering, a certificate signed by the Company and its underwriters) stating that
in the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than 120 days after receipt
of the request of the Initiating Holders; provided, however, that the Company
                                          --------  -------                  
may not utilize this right more than once in any twelve-month period.

          (d)  In addition, the Company shall not be obligated to effect, or to
take any action to effect:

                    (i)   Any registration pursuant to clause 1.2(a)(x) after
the Company has effected a total of two registrations pursuant thereto;

                    (ii)  Any registration pursuant to clause 1.2(a)(y) after
the Company has effected a total of two registrations pursuant thereto; and

                    (iii) Any registration pursuant to this Section 1.2 during
the period starting with the date thirty (30) days prior to the Company's good
faith estimate of the date of filing of, and ending on a date one hundred eighty
(180) days after the effective date of, a registration subject to Section 1.3
hereof; provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective;
provided that the Company must file such registration statement within 60 days
of the estimated filing date or the Company's ability to delay such registration
pursuant to this clause shall not apply.

          1.3  Company Registration.  If (but without any obligation to do so)
               --------------------                                           
the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
stock or other securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration relating
solely to the sale of securities to participants in a Company stock plan, a
registration on any form which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities or a 

                                       5
<PAGE>
 
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered),
the Company shall, at such time, promptly give each Holder written notice of
such registration. Upon the written request of each Holder given within twenty
(20) days after mailing of such notice by the Company in accordance with Section
4.5, the Company shall, subject to the provisions of Section 1.8, cause to be
registered under the 1933 Act all of the Registrable Securities that each such
Holder has requested to be registered.

          1.4  Obligations of the Company.  Whenever required under this Section
               --------------------------                                       
1 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

          (a)  Prepare and file with the SEC as promptly as practicable a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become effective, and, upon
the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for a period
of up to one hundred twenty (120) days or until the distribution contemplated in
the Registration Statement has been completed, whichever is less; provided,
                                                                  -------- 
however, that (i) such 120-day period shall be extended for a period of time
- -------                                                                     
equal to the period the Holder refrains from selling any securities included in
such registration at the request of an underwriter of Common Stock (or other
securities) of the Company, and (ii) in the case of any registration of
Registrable Securities on Form S-3 which are intended to be offered on a
continuous or delayed basis, such 120-day period shall be extended, if
necessary, to keep the registration statement effective until all such
Registrable Securities are sold, provided that Rule 415, or any successor rule
under the 1933 Act, permits an offering on a continuous or delayed basis, and
provided further that applicable rules under the 1933 Act governing the
obligation to file a post-effective amendment permit, in lieu of filing a post-
effective amendment which (I) includes any prospectus required by Section
10(a)(3) of the 1933 Act or (II) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (I) and (II) above to be contained in periodic reports filed pursuant to
Section 13 or 15(d) of the 1934 Act in the registration statement; provided,
further, that the Company is not obligated to maintain the effectiveness of the
foregoing registration statements beyond such time where the Holders may sell
their respective registered but unsold Registrable Securities for such
registration statement pursuant to Section 1.16(b) hereof, provided, the Company
shall provide to each such Holder at least twenty (20) days' prior written
notice of the termination of effectiveness of such registration statement.

          (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
1933 Act with respect to the disposition of all securities covered by such
registration statement.

          (c)  Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other 

                                       6
<PAGE>
 
documents as they may reasonably request in order to facilitate the disposition
of Registrable Securities owned by them.

          (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act.

          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

          (g)  Cause all such Registrable Securities registered pursuant to this
Agreement to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

          (h)  Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to this Agreement and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

          (i)  In the event of the issuance of a stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Common Stock included in such registration statement for sale in any
jurisdiction in the United States, the Company will promptly notify the holders
of Registrable Securities and will use its best efforts to obtain promptly the
withdrawal of such order.

          (j)  Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Section 1, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to this Section 1, if such securities are being
sold through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting

                                       7
<PAGE>
 
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

          1.5  Furnish Information.
               ------------------- 

          (a)  It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Section 1 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of such securities as shall be
required (to comply with applicable laws) to effect the registration of such
Holder's Registrable Securities.

          (b)  The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 or Section 1.12 if, due to the
operation of subsection 1.5(a), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in subsection 1.2(a) or subsection
1.12(b)(2), whichever is applicable.

          1.6  Expenses of Demand Registration.  All expenses other than
               -------------------------------                          
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel for the selling Holders
selected by holders of a majority of the Registrable Securities to be included
in such registration and reasonably acceptable to the Company shall be borne by
the Company; provided, however, that the Company shall not be required to pay
             --------  -------                                               
for any expenses of any registration proceeding begun pursuant to Section 1.2 if
the registration request is subsequently withdrawn at the request of the
Initiating Holders holding a majority of the Registrable Securities to be
registered (in which case all participating Holders shall bear such expenses),
unless such Holders agree to forfeit their right to one demand registration
pursuant to Section 1.2; provided further, however, that if at the time of such
                         -------- -------  -------                             
withdrawal, the Holders have learned of a material adverse change in the
condition, business, or prospects of the Company from that known to the Holders
at the time of their request and have withdrawn the request with reasonable
promptness following disclosure by the Company of such material adverse change,
then the Holders shall not be required to pay any of such expenses and shall
retain their rights pursuant to Section 1.2.

          1.7  Expenses of Company Registration.  The Company shall bear and pay
               --------------------------------                                 
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto and 

                                       8
<PAGE>
 
the fees and disbursements of counsel for the Company and the reasonable fees
and disbursements of one counsel for the selling Holders selected by holders of
a majority of the Registrable Securities to be included in such registration and
reasonably acceptable to the Company, but excluding underwriting discounts and
commissions relating to Registrable Securities.

          1.8  Underwriting Requirements.  In connection with any offering
               -------------------------                                  
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters) which terms will be customary
for transactions of that type, and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success
of the offering by the Company.  If the total amount of securities, including
Registrable Securities, requested by shareholders to be included in such
offering exceeds the amount of securities sold other than by the Company that
the underwriters determine in their sole discretion is compatible with the
success of the offering, then the Company shall be required to include in the
offering only that number of such securities, including Registrable Securities,
which the underwriters determine in their sole discretion will not jeopardize
the success of the offering.  The priority of securities to be included in any
registration effected in accordance with Section 1.3 shall be (i) first, the
securities the Company proposes to sell, (ii) second, Registrable Securities
(other than Excluded Shares) pro rata among the holders of Registrable
Securities requesting to include shares in such registration, based upon the
number of Registrable Securities such Holders desire to include in such
registration and (iii) third, other securities, if any are requested to be
included in such registration.

          1.9  Delay of Registration.  No Holder shall have any right to obtain
               ---------------------                                           
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

          1.10 Indemnification.  In the event any Registrable Securities are
               ---------------                                              
included in a registration statement under this Section 1:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the 1933 Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the 1933 Act or the 1934 Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the 1933 Act, the 1934 Act, other federal or state securities laws or any
other applicable federal or state law, insofar as such losses, claims, damages,
or liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"VIOLATION"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the 1933 Act, the 1934 Act, any state securities law or any rule or
regulation 

                                       9
<PAGE>
 
promulgated under the 1933 Act, the 1934 Act or any state securities law; and
the Company will pay to each such Holder, underwriter or controlling person, as
incurred, any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
        --------  -------                                        
subsection 1.10(a) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability, or action if such settlement is effected without
the consent of the Company (which consent shall not be unreasonably withheld),
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability, or action to the extent that it arises out of or is based
upon a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
any such Holder, underwriter or controlling person. The foregoing indemnity
agreements of the Company and Holders are subject to the condition that, insofar
as they relate to any Violation made in a preliminary prospectus but eliminated
or remedied in the amended prospectus on file with the SEC at the time the
registration statement in question becomes effective or the amended prospectus
filed with the SEC pursuant to SEC Rule 424(b) (the "FINAL PROSPECTUS"), such
indemnity agreement shall not inure to the benefit of any person if a copy of
the Final Prospectus was furnished to the indemnified party and was not
furnished to the person asserting the loss, liability, claim or damage at or
prior to the time such action is required by the 1933 Act.)

          (b)  To the extent permitted by law, each selling Holder, severally
and not jointly, will indemnify and hold harmless the Company, each of its
directors, each of its officers who has signed the registration statement, each
person, if any, who controls the Company within the meaning of the 1933 Act, any
underwriter, any other Holder selling securities in such registration statement
and any controlling person of any such underwriter or other Holder, against any
losses, claims, damages, or liabilities (joint or several) to which any of the
foregoing persons may become subject, under the 1933 Act, the 1934 Act or other
federal or state securities laws, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration;
and each such Holder will pay any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this subsection 1.10(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
                      --------  -------                                        
in this subsection 1.10(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided, that, in no event shall any indemnity under this subsection
1.10(b) exceed the gross proceeds from the offering received by such Holder.

          (c)  Promptly after receipt by an indemnified party under this Section
1.10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.10, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, 

                                      10
<PAGE>
 
that an indemnified party (together with all other indemnified parties which may
be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with the fees and expenses to be paid by the indemnifying
party, if representation of such indemnified party by the counsel retained by
the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if materially prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
under this Section 1.10, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 1.10.

          (d)  If the indemnification provided for in this Section 1.10 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations.  The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.  The Company and each Holder agree that it would not be
just and equitable if contribution pursuant to this Section 1.10(d) were
determined by pro rata allocation or by any other method of allocation which
              --- ----                                                      
does not take into account the equitable considerations referred to above in
this Section 1.10(d).  The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this Section 1.10(d) shall include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to indemnification or contribution from any person who
was not guilty of such fraudulent misrepresentation.

          (e)  Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

          (f)  The obligations of the Company and Holders under this Section
1.10 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

          1.11 Reports Under Securities Exchange Act of 1934.  With a view to
               ---------------------------------------------                 
making available to the Holders the benefits of Rule 144 promulgated under the
1933 Act and any other rule or regulation of the SEC that may at any time permit
a Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to:

          (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

          (b)  use its best efforts to take such action, including the voluntary
registration of its Common Stock under Section 12 of the 1934 Act, as is
necessary to enable the Holders to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the
end of the fiscal year in which the first registration statement filed by the
Company for the offering of its securities to the general public is declared
effective;

          (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act; and

          (d)  furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company), the 1933 Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

          1.12 Form S-3 Registration.  In case the Company shall receive from
               ---------------------                                         
any Holder or Holders of (i) at least twenty percent (20%) of the Registrable
Securities then outstanding or (ii) at least 15% of the Registrable Securities
issued upon conversion of the Series C Preferred Stock or any securities issued
upon conversion of the Series C Preferred Stock a written request or requests
that the Company effect a registration on Form S-3 and any related qualification
or compliance with respect to all or a part of the Registrable Securities owned
by such Holder or Holders, the Company will:

          (a)  promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

          (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any 

                                      12
<PAGE>
 
other Holder or Holders joining in such request as are specified in a written
request given within 15 days after receipt of such written notice from the
Company; provided, however, that the Company shall not be obligated to effect
         --------  ------- 
any such registration, qualification or compliance, pursuant to this section
1.12: (1) if Form S-3 is not available for such offering by the Holders; (2) if
the Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at an aggregate price to the
public (net of any underwriters' discounts or commissions) of less than
$500,000; (3) if the Company shall furnish to the Holders a certificate signed
by the President of the Company stating that in the good faith judgment of the
Board of Directors of the Company, it would be seriously detrimental to the
Company and its shareholders for such Form S-3 Registration to be effected at
such time, in which event the Company shall have the right to defer the filing
of the Form S-3 registration statement for a period of not more than 60 days
after receipt of the request of the Holder or Holders under this Section 1.12;
provided, however, that the Company shall not utilize this right more than once
in any twelve month period; (4) if the Company has, within the twelve (12) month
period preceding the date of such request, already effected two registrations on
Form S-3 for the Holders pursuant to this Section 1.12; or (5) in any particular
jurisdiction in which the Company would be required to qualify to do business or
to execute a general consent to service of process in effecting such
registration, qualification or compliance.

          (c)  Subject to the foregoing, the Company shall file a registration
statement covering the Registrable Securities and other securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Holders.  All expenses incurred in connection with the first registration
requested pursuant to Section 1.12(i) and the first registration requested
pursuant to Section 1.12(ii), including (without limitation) all registration,
filing, qualification, printer's and accounting fees and the reasonable fees and
disbursements of counsel for the selling Holder or Holders and counsel for the
Company, but excluding any underwriters' discounts or commissions, shall be
borne by the Company and thereafter pro rata by the Holder or Holders, provided
that registrations effected pursuant to this Section 1.12 shall not be counted
as demands for registration or registrations effected pursuant to Sections 1.2
or 1.3, respectively.

          1.13 Assignment of Registration Rights.  The rights to cause the
               ---------------------------------                          
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities, provided:  (a) the Company is, within a reasonable
time after such transfer, furnished with written notice of the name and address
of such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.15 below;
and (c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the 1933 Act.

          1.14 Limitations on Subsequent Registration Rights.  From and after
               ---------------------------------------------                 
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of at 

                                      13
<PAGE>
 
least two-thirds (2/3) of the then outstanding Registrable Securities, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 1.2 hereof, unless under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of
such securities will not reduce the amount of the Registrable Securities of the
Holders which is included, or (b) to make a demand registration which could
result in such registration statement being declared effective prior to the
earlier of either of the dates set forth in subsection 1.2(a) or within one
hundred twenty (120) days of the effective date of any registration effected
pursuant to Section 1.2.

          1.15 "Market Stand-Off" Agreement.  Each Holder hereby agrees that,
               ----------------------------                                  
during the period of duration specified by the Company and an underwriter of
Common Stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the 1933 Act, it shall not,
to the extent requested by the Company and such underwriter, directly or
indirectly sell, offer to sell, contract to sell (including, without limitation,
any short sale), grant any option to purchase or otherwise transfer or dispose
of (other than to donees who agree to be similarly bound) any securities of the
Company held by it at any time during such period except common stock included
in such registration; provided, however, that:

          (a)  such agreement shall be applicable only to the first such
registration statement of the Company which covers common stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

          (b)  all officers and directors of the Company and all other persons
with registration rights (whether or not pursuant to this Agreement) enter into
similar agreements; and

          (c)  such market stand-off time period shall not exceed one hundred
and eighty (180) days.

          In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Holder (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

          Notwithstanding the foregoing, the obligations described in this
Section 1.15 shall not apply to a registration relating solely to employee
benefit plans on Form S-l or Form S-8 or similar forms which may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-14 or Form S-15 or similar forms which may be promulgated
in the future.

          1.16 Termination of Registration Rights.
               ----------------------------------

          (a)  No Holder shall be entitled to exercise any right provided for in
this Section 1 after seven (7) years following the sale of securities pursuant
to a registration statement filed by the Company under the 1933 Act in
connection with the Minimum Offering.

          (b)  In addition, the right of any Holder to request registration or
inclusion in any registration pursuant to Section 1 shall terminate on the
closing of the first Company-initiated registered public offering of Common
Stock of the Company if all shares of Registrable Securities held or entitled to
be held upon conversion by such Holder may be sold under Rule 144 during any 90-
day period, or on such date after the closing of the first Company-initiated
registered public offering of Common Stock of the Company as all shares of
Registrable Securities held or entitled to be held upon conversion by such
Holder may be sold under Rule 144 during any 90-day period.

adjustment; and

          (f)  such other information relating to the financial condition,

assignee of the Investor may from time to time request, provided, however, that
                                                        --------  -------      
the Company shall not be obligated under this subsection (f) or any other
subsection of Section 2.1 to provide information which it deems in good faith to

               ----------

the Company shall not be obligated pursuant to this Section 2.2 to provide
access to any information which it reasonably considers to be a trade secret or
similar confidential information, unless such Investor has signed an agreement
to keep such information confidential.

          2.3  Termination of Information and Inspection Covenants.  The
               ---------------------------------------------------      
covenants set forth in subsections 2.1(b), (c), (d) and (f) shall terminate as
to Investors and be of no further force or effect upon the consummation of an
initial public offering of the Company's Common Stock underwritten by a
nationally recognized investment bank pursuant to a registration statement filed
and declared effective under the 1933 Act at a public offering price of at least
$5.00 per share (as adjusted for stock splits, stock dividends and like events)
that results in gross proceeds to the Company of not less than $30 million
(prior to expenses and underwriting commissions) and such Common Stock shall be
listed in the Nasdaq National Market, the American Stock Exhcange or the New
York Stock Exchange or other national securities market or exchange (a
"QUALIFIED IPO"), provided that, in the event the covenants set forth in
subsections 2.1(c), (d) and (f) have not terminated and the Company is complying
with the reporting requirements of the Securities and Exchange Commission for
public companies, the Investors agree to take reasonable steps to maintain the
confidentiality of non-public information.  The covenants set forth in Section
2.2 shall terminate as to Investors and be of no further force or effect upon
the consummation of a sale of securities pursuant to a registration statement
filed by the Company under the 1933 Act in connection with an offering of its
securities to the general public.

          2.4  Right of First Offer.  Subject to the terms and conditions
               --------------------                                      
specified in this Section 2.4, the Company hereby grants to each Investor a
right of first offer with respect to 

                                      16
<PAGE>
 
future sales by the Company of its Shares (as hereinafter defined). For purposes
of this Section 2.4, Investor includes any general partners and affiliates of an
Investor. An Investor shall be entitled to apportion the right of first offer
hereby granted it among itself and its partners and affiliates in such
proportions as it deems appropriate.

          Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital
stock ("SHARES"), the Company shall first make an offering of such Shares to
each Investor in accordance with the following provisions:

          (a) The Company shall deliver a notice ("NOTICE") to the Investors
stating (i) its bona fide intention to offer such Shares, (ii) the number of
such Shares to be offered, and (iii) the price and terms, if any, upon which it
proposes to offer such Shares.

          (b) Within 20 calendar days after receipt of the Notice, the Investor
may elect to purchase or obtain, at the price and on the terms specified in the
Notice, up to that portion of such Shares which equals the proportion that the
number of shares of common stock issued and held, or issuable upon conversion of
the Preferred Stock and warrants to purchase Preferred Stock, then held by such
Investor bears to the total number of shares of outstanding common stock of the
Company (assuming conversion of all outstanding securities which are, by their
terms, convertible into or exchangeable for, common stock). The Company shall
promptly, in writing, inform each Investor which purchases all the shares
available to it ("FULLY-EXERCISING INVESTOR") of any other Investor's failure to
do likewise. During the twenty-day period commencing after receipt of such
information, each Fully-Exercising Investor shall be entitled to obtain that
portion of the Shares for which Investors were entitled to subscribe but which
were not subscribed for by the Investors which is equal to the proportion that
the number of shares of common stock issued and held, or issuable upon
conversion of the Preferred Stock and warrants to purchase Preferred Stock then
held, by such Fully-Exercising Investor bears to the total number of shares of
common stock issued and held, or issuable upon conversion of the Preferred Stock
and warrants to purchase Preferred Stock, then held, by all Fully-Exercising
Investors who wish to purchase some of the unsubscribed shares.

          (c) If all Shares referred to in the Notice which the Investors are
entitled to purchase are not elected to be obtained as provided in subsection
2.4(b) hereof, the Company may, during the 60-day period following the
expiration of the period provided in subsection 2.4(b) hereof, offer the
remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than those
specified in the Notice.  If the Company does not enter into an agreement for
the sale of the Shares within such period, or if such agreement is not
consummated within 60 days of the execution thereof, the right provided
hereunder shall be deemed to be revived and such Shares shall not be offered
unless first reoffered to the Investors in accordance herewith.

          (d) The right of first offer in this Section 2.4 shall not be
applicable (i) to the issuance or sale of up to 3,438,900 shares of common stock
(or options therefor) under the 1995 Stock Option and 1997 Equity Incentive
Plans (the "PLANS") of the Company (in addition to the

                                      17
<PAGE>
 
number of options granted and exercised to date or canceled hereafter) to
employees, officers and directors for the primary purpose of soliciting or
retaining their employment and/or services, and as such number may be increased
hereafter by affirmative vote of a least 75% of the Board of Directors, (ii) to
or after consummation of a Qualified IPO, (iii) to the issuance of securities
pursuant to the conversion or exercise of convertible or exercisable securities
which were, when originally issued, not subject to the right of first offer
effected by this Section 2.4, (iv) to the issuance of securities in connection
with a bona fide business acquisition of or by the Company, whether by merger,
consolidation, sale of assets, sale or exchange of stock or otherwise, or (v) to
the issuance of stock, warrants or other securities or rights to persons or
entities with which the Company has business relationships provided such
issuances are for other than primarily equity financing purposes and are
approved by the Board of Directors.

          (e) The right of first offer set forth in this Section 2.4 may not be
assigned or transferred, except that (i) such right is assignable by each Holder
to any wholly owned subsidiary or parent of, or to any corporation or entity
that is, within the meaning of the 1933 Act, controlling, controlled by or under
common control with (for example, the same investment manager or advisor), any
such Holder, and (ii) such right is assignable between and among any of the
Holders.

          2.5  Observer Rights.  As long as an Investor and its affiliates owns
               ---------------                                                 
not less than 500,000 shares of the Company's Preferred Stock (or an equivalent
amount of Common Stock issued upon conversion thereof) and does not have a
representative on the Board of Directors of the Company and so long as Fleet
Equity Partners or its affiliates ("FLEET") owns 500,000 shares of Preferred
Stock, the Company shall invite one representative of each of such Investor and
Fleet to attend all meetings of its Board of Directors and any annual strategic
planning sessions in a nonvoting observer capacity and, in this respect, shall
give such representative copies of all notices, minutes, consents, and other
materials that it provides to its directors with respect to such meeting;
provided, however, that such representative shall agree to hold in confidence
- --------  -------                                                            
and trust and to act in a fiduciary manner with respect to all information so
provided; and, provided further, that the Company reserves the right to withhold
               -------- -------                                                 
any information and to exclude such representative from any meeting or portion
thereof if access to such information or attendance at such meeting could
adversely affect the attorney-client privilege between the Company and its
counsel or would result in disclosure of trade secrets to such representative or
if such Investor or its representative is a direct competitor of the Company.

          2.6  Termination of Certain Covenants.  The covenants set forth in
               --------------------------------                             
Sections 2.4 and 2.5 shall terminate as to Investors and be of no further force
or effect upon a Qualified IPO.  In the event that the Company becomes subject
to the reporting requirements of the Securities and Exchange Commission through
some mechanism other than a Qualified IPO, the covenants set forth in Sections
2.4 and 2.5 shall continue in full force and effect provided that the Investors
sign an agreement to maintain the confidentiality of confidential information.

          3.   Covenants of the Investors, Common Shareholders and the Company.
               --------------------------------------------------------------- 

                                      18

          3.1  Right of First Offer for Common Shares.  Subject to the terms and
               --------------------------------------                           
conditions specified in this Section 3.1, each Common Shareholder hereby grants
to the Company and each Investor a right of first offer with respect to future
sales by such Common Shareholder of shares of the Company's Common Stock
registered in their respective names or beneficially now or hereafter owned by
them ("COMMON SHARES").  An Investor shall be entitled to apportion the right of
first offer hereby granted it among itself and its partners and affiliates in
such proportions as it deems appropriate.

          Each time a Common Shareholder proposes to offer any Common Shares,
such Common Shareholder shall first make an offering of such Common Shares to
the Company and the Investors in accordance with the following provisions:

          (a) The Common Shareholder shall deliver a notice ("COMMON NOTICE") to
the Company stating (i) its bona fide intention to offer such Common Shares,
(ii) the number of such Common Shares to be offered, and (iii) the price and
terms, if any, upon which it proposes to offer such Common Shares.

          (b) Within 20 calendar days after receipt of the Common Notice, the
Company may elect to purchase or obtain, at the price and on the terms specified
in the Common Notice, such Common Shares.

          (c) If all Common Shares referred to in the Common Notice which the
Company is entitled to purchase are not elected to be obtained as provided in
subsection (b) hereof, the Common Shareholder shall offer the unsubscribed
portion of such Common Shares to the Investors at the price and upon the terms
specified in the Common Notice.  Within 20 calendar days after the Company
provides the Common Shareholder and the Investors notice (the "COMPANY NOTICE")
of its intention not to purchase all of the Common Shares, the Investors may
elect to purchase or obtain, at the price and on the terms specified in the
Common Notice, such Common Shares.

          (d) The Company Notice shall state (i) the Company's intention not to
purchase all the Common Shares being offered, (ii) the number of such Common
Shares to be offered to the Investors, and (iii) the price and terms, if any,
upon which such Common Shares are being offered.  Within 20 calendar days after
receiving the Company Notice, each Investor may elect to purchase or obtain, at
the price and on the terms specified in the Company Notice, up to that portion
of the Common Shares which equals the proportion that the number of shares of
common stock issued and held or issuable upon conversion of the Preferred Stock,
then held by such Investor bears to the total number of shares of outstanding
common stock of the Company (assuming full conversion of all outstanding
securities which are, by their terms, convertible into or exchangeable for,
common stock).  The Company shall promptly inform each Investor which purchases
all the shares available to it ("SECTION 3 FULLY-EXERCISING INVESTOR") of any
other Investor's failure to do likewise.  During the 10 calendar day period
commencing after giving of such information, each Section 3 Fully-Exercising
Investor shall be entitled to obtain that portion of the Common Shares for which
Investors were entitled to subscribe but which were not subscribed for by the
Investors which is equal to the proportion that the number 

                                      19
<PAGE>
 
of shares of common stock issued and held, or issuable upon conversion of the
Preferred Stock then held, by such Section 3 Fully-Exercising Investor bears to
the total number of shares of common stock issued and held, or issuable upon
conversion of the Preferred Stock, then held, by all Section 3 Fully-Exercising
Investors who wish to purchase some of the unsubscribed shares.

          (e)  If all Common Shares referred to in the Notice which the Company
and the Investors are entitled to purchase are not elected to be obtained as
provided in subsections (b) and (d) hereof, the Common Shareholder may, during
the 60-day period following the expiration of the period provided in subsection
(d) hereof, offer the remaining unsubscribed portion of such Shares to any
person or persons at a price not less than, and upon terms substantially the
same as those specified in the Common Notice.  If the Common Shareholder does
not enter into an agreement for the sale of the Common Shares within such
period, or if such agreement is not consummated within 60 days of the execution
thereof, the right provided hereunder shall be deemed to be revived and such
Common Shares shall not be offered unless first reoffered to the Company and the
Major Investors in accordance herewith.

          (f)  The right of first offer in this Section 3.1 shall terminate
after consummation of a Qualified IPO.

          (g)  The right of first offer set forth in this Section 3.1 may not be
assigned or transferred, except that (i) such right is assignable by each Holder
to any wholly owned subsidiary or parent of, or to any corporation or entity
that is, within the meaning of the 1933 Act, controlling, controlled by or under
common control with, any such Holder, (ii) such right is assignable between and
among any of the Holders and (iii) such right is assignable in connection with
the transfer of Investor shares made in accordance with this Agreement.

          (h)  The right of first offer in this Section 3.1 shall not apply to
any transfers of Common Shares to any affiliates of any Common Shareholder, bona
fide gifts by any Common Shareholder, any distribution in kind to the equity
holders of such Common Shareholder, any disposition by a Common Shareholder in
connection with the liquidation, dissolution or winding up of such Investor or
any transfer pursuant to that certain Contingent Share Transfer Agreement, dated
as of even date herewith, by and among certain holders of Series A Preferred
Stock, Series B Preferred Stock and Common Shares (the "CONTINGENT SHARE
TRANSFER AGREEMENT").

          3.2  Right of First Offer for Investor Shares.  Subject to the terms
               ----------------------------------------                       
and conditions specified in this Section 3.2, each Investor hereby grants to
each other Investor a right of first offer with respect to future sales by such
Investor of shares of the Company's Preferred Stock and Common Stock registered
in their respective names or beneficially now or hereafter owned by them
("INVESTOR SHARES").  An Investor shall be entitled to apportion the right of
first offer hereby granted it among itself and its partners and affiliates in
such proportions as it deems appropriate.

          Each time an Investor proposes to offer any Investor Shares, such
Investor shall first make an offering of such Investor Shares to the other
Investors in accordance with the following provisions:

                                      20
<PAGE>
 
          (a)  The Investor shall deliver a notice ("INVESTOR NOTICE") to each
Investor stating (i) its bona fide intention to offer such Investor Shares, (ii)
the number of such Investor Shares to be offered, and (iii) the price and terms,
if any, upon which it proposes to offer such Investor Shares.

          (b)  Within 20 calendar days after receipt of the Investor Notice,

                            As Adopted May 19, 1995

     1.   PURPOSE.  This 1995 Stock Option Plan ("Plan") is established as a
          -------                                 ----                      
compensatory plan to attract, retain and provide equity incentives to selected
persons to promote the financial success of Exodus Communications, Inc., a
California corporation (the "Company").  Capitalized terms not previously
                             -------                                     
defined herein are defined in Section 17 of this Plan.

     2.   TYPES OF OPTIONS AND SHARES.  Options granted under this Plan (the
          ---------------------------                                       
"Options") may be either (a) incentive stock options ("ISOs") within the meaning
- --------                                               ----                     
of Section 422 of the Internal Revenue Code of 1986, as amended (the "Revenue
                                                                      -------
Code"), or (b) nonqualified stock options ("NQSOs"), as designated at the time
- ----                                        -----                             
of grant.  The shares of stock that may be purchased upon exercise of Options
granted under this Plan are shares of the common stock of the Company (the
                                                                          
"Shares").
- -------   

     3.   NUMBER OF SHARES.  The aggregate number of Shares that may be issued
          ----------------                                                    
pursuant to Options granted under this Plan is 900,000 Shares, subject to
adjustment as provided in this Plan.  If any Option expires or is terminated
without being exercised in whole or in part, the unexercised or released Shares
from such Option shall be available for future grant and purchase under this
Plan.  At all times during the term of this Plan, the Company shall reserve and
keep available such number of Shares as shall be required to satisfy the
requirements of outstanding Options under this Plan.

     4.   ELIGIBILITY. Options may be granted to employees, officers, directors,
          -----------
consultants and advisers (provided such consultants and advisers render bona
fide services not in connection with the offer and sale of securities in a
capital-raising transaction) of the Company or any Parent, Subsidiary or
Affiliate of the Company. ISOs may be granted only to employees (including
officers and directors who are also employees) of the Company or a Parent or
Subsidiary of the Company. The Committee (as defined in Section 14) in its sole
discretion shall select the recipients of Options ("Optionees"). An Optionee may
                                                    ---------   
be granted more than one Option under this Plan. The Company may also, from time
to time, substitute or assume outstanding options granted by another company,
whether in connection with an acquisition of such other company or otherwise, by
either (a) granting an Option under this Plan in replacement of the option
assumed by the Company, or (b) treating the assumed option as if it had been
granted under this Plan if the terms of such assumed option could be applied to
an Option granted under this Plan. Such substitution or assumption shall be
permissible if the holder of the substituted or assumed option would have been
eligible to be granted an Option hereunder if the other company had applied the
rules of this Plan to such grant.

     5.   TERMS AND CONDITIONS OF OPTIONS. The Committee shall determine whether
          -------------------------------
each Option is to be an ISO or an NQSO, the number of Shares subject to the
Option, the exercise price of the Option, the period during which the Option may
be exercised, and all other terms and conditions of the Option, subject to the
following:

          5.1  Form of Option Grant.  Each Option granted under this Plan shall
               --------------------                                            
be evidenced by a written Stock Option Grant (the "Grant") in such form (which
                                                   -----                      
need not be the same for each Optionee) as the Committee shall from time to time
approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.

          5.2  Date of Grant.  The date of grant of an Option shall be the date
               -------------                                                   
on which the Committee makes the determination to grant such Option unless
otherwise specified by the Committee.  The Grant representing the Option will be
delivered to Optionee with a copy of this Plan within a reasonable time after
the granting of the Option.

          5.3  Exercise Price.  The exercise price of an Option shall be
               --------------                                           
determined by the Committee when the Option is granted and may not be less than
100% of the Fair Market Value of the Shares on the date the Option is granted.
The exercise price of any Option granted to a person owning more than 10% of the
total combined voting power of all classes of stock of the Company or any Parent
or Subsidiary of the Company ("Ten Percent Shareholder") shall not be less than
                               -----------------------                         
110% of the Fair Market Value of the Shares on the date the Option is granted.

          5.4  Exercise Period. Options shall be exercisable within the times or
               ---------------
upon the events determined by the Committee as set forth in the Grant; provided,
however, that no Option shall be exercisable after the expiration of ten (10)
years from the date the Option is granted, and provided further that no ISO
granted to a Ten Percent Shareholder shall be exercisable after the expiration
of five (5) years from the date the Option is granted.

          5.5  Limitations on ISOs.  The aggregate Fair Market Value (determined
               -------------------                                              
as of the time an Option is granted) of stock with respect to which ISOs are
exercisable for the first time by an Optionee during any calendar year (under
this Plan or under any other incentive stock option plan of the Company or any
Parent or Subsidiary of the Company) shall not exceed $100,000.  If the Fair
Market Value of Shares of Shares with respect to which ISOs are exercisable for
the first time by an Optionee during any calendar year exceeds $100,000, the
Options for the first $100,000 worth of Shares to become exercisable in such
year shall be ISOs and the Options for the amount in excess of $100,000 that
becomes exercisable in that year shall be NQSOs.  In the event that the Revenue
Code or the regulations promulgated thereunder are amended after the effective
date of this Plan to provide for a different limit on the Fair Market Value of
Shares permitted to be subject to ISOs, such different limit shall be
incorporated herein and shall apply to any Options granted after the effective
date of such amendment.

          5.6  Options Non-Transferable.  Options granted under this Plan, and
               ------------------------                                       
any interest therein, shall not be transferable or assignable by Optionee, and
may not be made subject to execution, attachment or similar process, otherwise
than by will or by the laws of descent and distribution or pursuant to a
qualified domestic relations order as defined by the Code or Title I 

                                       2
<PAGE>
 
of the Employee Retirement Income Security Act, or the rules thereunder, and
shall be exercisable during the lifetime of Optionee only by Optionee.

          5.7  Assumed Options.  In the event the Company assumes an option
               ---------------                                             
granted by another company, the terms and conditions of such option shall remain
unchanged (except the exercise price and the number and nature of shares
issuable upon exercise, which will be adjusted appropriately pursuant to Section
424(c) of the Revenue Code).  In the event the Company elects to grant a new
option rather than assuming an existing option (as specified in Section 4), such
new option need not be granted at Fair Market Value on the date of grant and may
instead be granted with a similarly adjusted exercise price.

     6.   EXERCISE OF OPTIONS.
          ------------------- 

          6.1  Notice.  Options may be exercised only by delivery to the Company
               ------                                                           
of a written stock option exercise agreement (the "Exercise Agreement") in a
                                                   ------------------       
form approved by the Committee (which need not be the same for each Optionee),
stating the number of Shares being purchased, the restrictions imposed on the
Shares, if any, and such representations and agreements regarding Optionee's
investment intent and access to information, if any, as may be required by the
Company to comply with applicable securities laws, together with payment in full
of the exercise price for the number of Shares being purchased.

          6.2  Payment.  Payment for the Shares may be made in cash (by check)
               -------                                                        
or, where approved by the Committee in its sole discretion and where permitted
by law:  (a) by cancellation of indebtedness of the Company to the Optionee; (b)
by surrender of shares of common stock of the Company, free and clear of all
liens, claims, encumbrances and security interests, having a Fair Market Value
equal to the applicable exercise price of the Options that have been owned by
Optionee for more than six (6) months (and which have been paid for within the
meaning of the Securities and Exchange Commission ("SEC") Rule 144 and, if such
                                                    ---                        
Shares were purchased from the Company by use of a promissory note, such note
has been fully paid with respect to such shares), or were obtained by Optionee
in the open public market; (c) by waiver of compensation due or accrued to
Optionee for services rendered; (d) provided that a public market for the
Company's stock exists, through a "same day sale" commitment from Optionee and a
broker-dealer that is a member of the National Association of Securities Dealers
(a "NASD Dealer") whereby Optionee irrevocably elects to exercise the Option and
    -----------                                                                 
to sell a portion of the Shares so purchased to pay for the exercise price and
whereby the NASD Dealer irrevocably commits upon receipt of such Shares to
forward the exercise price directly to the Company; (e) provided that a public
market for the Company's stock exists, through a "margin" commitment from
Optionee and a NASD Dealer whereby Optionee irrevocably elects to exercise the
Option and to pledge the Shares so purchased to the NASD Dealer in a margin
account as security for a loan from the NASD Dealer in the amount of the
exercise price, and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the exercise price directly to the Company; or (f) by any
combination of the foregoing.

          6.3  Withholding Taxes.  Prior to issuance of the Shares upon exercise
               -----------------                                                
of an Option, Optionee shall pay or make adequate provision for any federal or
state withholding obligations of the Company, if applicable.  Where approved by
the Committee in its sole

                                       3
<PAGE>
 
discretion, Optionee may provide for payment of withholding taxes upon exercise
of the Option by requesting that the Company retain Shares with a Fair Market
Value equal to the minimum amount of taxes required to be withheld.  In such
case, the Company shall issue the net number of Shares to Optionee by deducting
the Shares retained from the Shares exercised.  The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined in accordance with Section 83 of the Revenue
Code (the "Tax Date").  All elections by Optionees to have Shares withheld for
           --------                                                           
this purpose shall be made in writing in a form acceptable to the Committee and
shall be subject to the following restrictions:

(a)  the election must be made on or prior to the applicable Tax Date and, once
     made, the election shall be irrevocable as to the particular Shares as to
     which the election is made; and

(b)  all elections shall be subject to the consent or disapproval of the
     Committee.

In addition, if Optionee is an Insider, and if the Company is subject to Section
16(b) of the Exchange Act, the following shall apply:

(c)  the election may not be made within six (6) months after the date of grant
     of the Option, except as otherwise permitted by Rule 16b-3(e) promulgated
     under Section 16 of the Exchange Act;

(d)  the election must be made either six (6) months prior to the Tax Date or in
     the 10-day period beginning on the third day following the public release
     of the Company's quarterly or annual summary statement of operations; and

(e)  if the Option is exercised within six (6) months after the date of grant
     and the Tax Date is deferred until six (6) months after the date of grant
     of the Option because no election is filed under Section 83(b) of the
     Revenue Code, Optionee shall receive the full number of Shares with respect
     to which the Option is exercised, but Optionee shall be unconditionally
     obligated to tender back to the Company the proper number of Shares on the
     Tax Date.

          6.4  Limitations on Exercise. Notwithstanding the exercise periods set
               -----------------------
forth in the Grant, exercise of an Option shall always be subject to the
following:

               6.4.1  If Optionee ceases to be employed by the Company or any
Parent, Subsidiary or Affiliate of the Company for any reason except death or
Disability, Optionee may exercise such Optionee's Options to the extent (and
only to the extent) that they would have been exercisable upon the date of
termination, within ninety (90) days after the date of termination (or such
shorter time period as may be specified in the Grant);

               6.4.2  If Optionee is an Insider and the Company is subject to
Section 16(b) of the Exchange Act and Optionee ceases to be employed by the
Company, Optionee's Option will remain exercisable, to the extent (and only to
the extent) that it was exercisable on the date of termination, until the later
of (a) the last date such Option would be exercisable under Section 6.4.1 or
6.4.3, as applicable, or (b) the end of the thirty (30) day period commencing on
the date

                                       4
<PAGE>
 
six (6) months after the grant of such Option, with any extension beyond ninety
(90) days after termination of employment deemed to be as an NQSO, and provided
further that in no event may an Option be exercisable later than the expiration
date of the Option;

               6.4.3  If Optionee's employment with the Company or any Parent,
Subsidiary or Affiliate of the Company is terminated because of the death or
Disability of Optionee, Optionee's Options may be exercised to the extent (and
only to the extent) that they would have been exercisable by Optionee on the
date of termination, by Optionee (or Optionee's legal representative) within
twelve (12) months after the date of termination (or such shorter time period of
no less than six (6) months as may be specified in the Grant), but in any event
no later than the expiration date of the Options.

               6.4.4  The Committee shall have discretion to determine whether
Optionee has ceased to be employed by the Company or any Parent, Subsidiary or
Affiliate of the Company, whether or not such cessation was due to Disability,
and the effective date on which such employment terminated.

               6.4.5  In the case of an Optionee who is a director, consultant
or adviser, the Committee will have the discretion to determine whether Optionee
is "employed by the Company or any Parent, Subsidiary or Affiliate of the
Company" pursuant to the foregoing Sections.

               6.4.6  The Committee may specify a reasonable minimum number of
Shares that may be purchased on any exercise of an Option, provided that such
minimum number will not prevent Optionee from exercising the full number of
Shares as to which the Option is then exercisable.

               6.4.7  An Option shall not be exercisable unless such exercise is
in compliance with all applicable federal and state securities laws, rules and
regulations of any governmental body and the requirements of any stock exchange
or national market system upon which the Shares may then be listed, as they are
in effect on the date of exercise. The Company shall be under no obligation to
register the Shares with the SEC or to effect compliance with the registration,
qualification or listing requirements of any other securities laws, stock
exchange or national market system, and the Company shall have no liability for
any inability or failure to do so.

     7.   RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
          ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Grant (a) a right of
first refusal to purchase all Shares that an Optionee (or a subsequent
transferee) may propose to transfer to a third party and/or (b) a right to
repurchase a portion of or all Shares held by an Optionee upon Optionee's
termination of employment or service with the Company or a Parent, Subsidiary or
Affiliate of the Company, for any reason within a specified time as determined
by the Committee at the time of grant at Optionee's original purchase price, the
Fair Market Value of such Shares or a price determined by a formula or other
provision set forth in the Grant.

     8.   MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS.  The Committee shall
          -----------------------------------------------                     
have the power to modify, extend or renew outstanding Options and to authorize
the grant of new Options 

                                       5
<PAGE>
 
in substitution therefor, provided that any such action may not, without the
written consent of Optionee, impair any rights under any Option previously
granted. Any outstanding ISO that is modified, extended, renewed or otherwise
altered shall be treated in accordance with Section 424(h) of the Revenue Code.
The Committee shall have the power to reduce the exercise price of outstanding
Options without the consent of Optionees by a written notice to the Optionees
affected; provided, however, that the exercise price per Share may not be
reduced below the minimum exercise price that would be permitted under Section
5.3 of this Plan for Options granted on the date the action is taken to reduce
the exercise price; and provided further that the exercise price may not be
reduced below the par value of the Shares.

     9.   STOCK OWNERSHIP; FINANCIAL STATEMENTS.  No Optionee shall have any of
          -------------------------------------                                
the rights of a shareholder with respect to any Shares subject to an Option
until such Option is properly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
such date, except as provided in this Plan.  However, the Company shall provide
to each Optionee, annually during the period for which he has one or more
Options outstanding, copies of the financial statements of the Company,
consisting of, at a minimum, a balance sheet and an income statement, at such
time after the close of each fiscal year of the Company as such statements are
released by the Company to its shareholders.  The Company shall not be required
to provide such information to key employees whose duties in connection with the
Company assume their access to equivalent information.

     10.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Option granted
          -----------------------                                             
under this Plan shall confer on any Optionee any right to continue in the employ
of, or other relationship with, the Company or any Parent, Subsidiary or
Affiliate of the Company or limit in any way the right of the Company or any
Parent, Subsidiary or Affiliate of the Company to terminate Optionee's
employment or other relationship at any time, with or without cause.

     11.  ADJUSTMENT OF OPTION SHARES.  In the event that the number of
          ---------------------------                                  
outstanding shares of common stock of the Company is changed by a stock
dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company
without consideration, or if a substantial portion of the assets of the Company
are distributed, without consideration in a spin-off or similar transaction, to
the share holders of the Company, the number of Shares available under this Plan
and the number of Shares subject to outstanding Options and the exercise price
per Share of such Options shall be proportionately adjusted, subject to any
required action by the Board of Directors (the "Board") or shareholders of the
                                                -----                         
Company and compliance with applicable securities laws; provided, however, that
a fractional share shall not be issued upon exercise of any Option and any
fractions of a Share that would have resulted shall either be cashed out at Fair
Market Value or the number of Shares issuable under the Option shall be rounded
up to the nearest whole number, as determined by the Committee; and provided
further that the exercise price may not be decreased to below the par value, if
any, for the Shares.

     12.  ASSUMPTION OF OPTIONS BY SUCCESSORS.
          ----------------------------------- 

          12.1  Assumption or Substitution.  In the event of (a) a merger or
                --------------------------                                  
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a 

                                       6
<PAGE>
 
wholly owned subsidiary, a reincorporation, or other transaction in which there
is no substantial change in the shareholders of the corporation and the Options
granted under this Plan are assumed or replaced by the successor corporation,
which assumption shall be binding on all Optionees), (b) a dissolution or
liquidation of the Company, (c) the sale of substantially all of the assets of
the Company, or (d) any other transaction which qualifies as a "corporate
transaction" under Section 424(a) of the Revenue Code wherein the shareholders
of the Company give up all of their equity interest in the Company (except for
the acquisition, sale or transfer of all or substantially all of the outstanding
shares of the Company), any or all outstanding Options may be assumed or
replaced by the successor corporation, which assumption shall be binding on all
Optionees. In the alternative, the successor corporation may substitute an
equivalent option or provide substantially similar consideration to Optionees as
was provided to shareholders (after taking into account the existing provisions
of Optionee's options, such as the exercise price and the vesting schedule). The
successor corporation may also issue, in place of outstanding shares of the
Company held by Optionee as a result of the exercise of an Option that is
subject to repurchase, substantially similar shares or other property subject to
similar repurchase restrictions no less favorable to Optionee.

          12.2  Expiration.  In the event such successor corporation, if any,
                ----------                                                   
refuses to assume or substitute Options, as provided above, pursuant to a
transaction described in Sections 12.1 above, or there is no successor
corporation, and if the Company is ceasing to exist as a separate corporate
entity, the Options shall, notwithstanding any contrary terms in the Grant,
expire on (and, in the case of a merger or consolidation described in Subsection
12.1(a) above, if the Company has reserved to itself a right to repurchase
Shares issued on exercise of Options at the original purchase price of such
Shares, such right shall terminate on), a date at least 20 days after the Board
gives written notice to Optionees specifying the terms and conditions of such
termination.

          12.3  Additional Provisions.  Subject to the foregoing provisions of
                ---------------------                                         
this Section 12, in the event of the occurrence of any transaction described in
Section 12.1, any outstanding Option shall be treated as provided in the
applicable agreement or plan of merger, consolidation, dissolution, liquidation,
sale of assets or other "corporate transaction".

     13.  ADOPTION AND SHAREHOLDER APPROVAL. This Plan shall become effective on
          ---------------------------------
the date that it is adopted by the Board of the Company. This Plan shall be
approved by the shareholders of the Company, in any manner permitted by
applicable corporate law, within twelve months before or after the date this
Plan is adopted by the Board. Upon the effective date of the Plan, the Board may
grant Options pursuant to this Plan; provided that, in the event that
shareholder approval is not obtained within the time period provided herein, all
Options granted hereunder shall terminate. No Option that is issued as a result
of any increase in the number of shares authorized to be issued under this Plan
shall be exercised prior to the time such increase has been approved by the
shareholders of the Company and all such Options granted pursuant to such
increase shall similarly terminate if such shareholder approval is not obtained.
After the Company becomes subject to Section 16(b) of the Exchange Act, the
Company will comply with the requirements of Rule 16b-3 with respect to
shareholder approval.

be entitled under this Option to purchase a number of shares of the Company's

         -----------------------                                               
exercise is in compliance with the Securities Act and all applicable state
securities laws as they are in effect on the date of exercise, and the
requirements of any stock exchange or national market system on which the

to effect such compliance.

     4.  TERMINATION OF OPTION.  Except as provided below in this Section, this

Option shall terminate and may not be exercised if Optionee ceases to be
employed by the Company or any Parent or Subsidiary of the Company (or, in the
case of a nonqualified stock option, an Affiliate of the Company).  Optionee
shall be considered to be employed by the Company for all purposes under Section
2 and this Section 4 if Optionee is an officer, director or full-time employee
of the Company or any Parent or Subsidiary (or, if applicable, Affiliate) of the
Company or if the Committee determines that Optionee is rendering substantial
services as a part-time employee, consultant or adviser to the Company or any
Parent or Subsidiary (or Affiliate) of the Company.  The Committee shall have
discretion to determine whether Optionee has ceased to be employed by the
Company or any Parent, Subsidiary (or Affiliate) of the Company and the
effective date on which such employment terminated (the "Termination Date").
                                                         ----------------   

          4.1  Termination Generally.  If Optionee ceases to be employed by the

Company or any Parent, Subsidiary or Affiliate of the Company for any reason
except death or Disability, this Option, to the extent (and only to the extent)
that it would have been exercisable by Optionee on the Termination Date, may be
exercised by Optionee within ninety (90) days after the Termination Date, but in
no event later than the Expiration Date.

          4.2  Death or Disability.  If Optionee's employment with the Company

Date, may be exercised by Optionee (or Optionee's legal representative) within
twelve (12) months after the Termination Date, but in no event later than the
Expiration Date.

               ----------------------                                          
confer on Optionee any right to continue in the employ of, or other relationship

     5.   MANNER OF EXERCISE.
          ------------------ 

          5.1  Exercise Agreement.  This Option shall be exercisable by delivery
               ------------------                                               
to the Company of an executed written Stock Option Exercise Agreement in the
form attached hereto as Exhibit A, or in such other form as may be approved by
                        ---------                                             
the Company, which shall set forth Optionee's election to exercise some or all
of this Option, the number of Shares being purchased, any restrictions imposed
on the Shares and such other representations and agreements as may be required
by the Company to comply with applicable securities laws.

          5.2  Exercise Price.  Such Exercise Agreement shall be accompanied by
               --------------                                                  
full payment of the Exercise Price for the Shares being purchased.  Payment for
the Shares may be made in cash (by check).

          5.3  Withholding Taxes.  Prior to the issuance of the Shares upon
               -----------------                                           
exercise of this Option, Optionee must pay or make adequate provision for any
applicable federal or state withholding obligations of the Company.  Optionee
may provide for payment of Optionee's minimum statutory withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld, all
as set forth in Section 6(c) of the Plan.  In such case, the Company shall issue
the net number of Shares to Optionee by deducting the Shares retained from the
Shares exercised.

          5.4  Issuance of Shares.  Provided that such notice and payment are in
               ------------------                                               
form and substance satisfactory to counsel for the Company, the Company shall
cause the Shares to be issued in the name of Optionee, Optionee's legal
representative or Optionee's donee.

     6.   NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the Option
          -------------------------------------------------                
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO within (a) the date
two years after the Date of Grant, or (b) the date one year after exercise of
the ISO with respect to the Shares to be sold or disposed, Optionee shall
immediately notify the Company in writing of such disposition.  Optionee
acknowledges and agrees that Optionee may be subject to income tax withholding
by the Company on the compensation income recognized by Optionee from any such
early disposition by payment in cash (or in Shares, to the extent permissible
under Section 5.3) or out of the current wages or other earnings payable to
Optionee.

     7.   NONTRANSFERABILITY OF OPTION.  If this Option is an ISO, then this
          ----------------------------                                      
Option may not be transferred in any manner other than by will or by the law of
descent and distribution and may be exercised during the lifetime of Optionee
only by Optionee.  Otherwise, this Option may only be transferred pursuant to a
qualified domestic relations order as defined by the Revenue Code or Title I of
the Employee Retirement Income Security Act, or the rules thereunder.  The terms
of this Option shall be binding upon the executors, administrators, successors
and assigns of Optionee.

                                                              Stock Option Grant


     8.   TAX CONSEQUENCES.  Set forth below is a brief summary as of the date
          ----------------                                                    
this form of Grant was adopted of some of the federal and California tax
consequences of exercise of this Option and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION
OR DISPOSING OF THE SHARES.

          8.1  Exercise of ISO.  If this Option qualifies as an ISO, there will
               ---------------                                                 
be no regular federal income tax liability or California income tax liability
upon the exercise of the Option, although the excess, if any, of the Fair Market
Value of the Shares on the date of exercise over the Exercise Price will be
treated as an adjustment to alternative minimum taxable income for federal
income tax purposes and may subject Optionee to an alternative minimum tax
liability in the year of exercise.

          8.2  Exercise of ISO on Disability.  If this Option qualifies as an
               -----------------------------                                 
ISO and has been exercised at any time following three (3) months after a
Termination Date that occurred due to the Disability of the Optionee not meeting
the requirements for total and permanent disability set forth in Section
22(e)(3) of the Revenue Code, then the exercise of this Option will be treated
as the exercise of a nonqualified option ("NQSO") described in Section 8.3
                                           ----                           
below.

          8.3  Exercise of Nonqualified Stock Option.  If this Option does not
               -------------------------------------                          
qualify as an ISO, there may be a regular federal income tax liability and a
California income tax liability upon the exercise of the Option.  Optionee will
be treated as having received compensation income (taxable at ordinary income
tax rates) equal to the excess, if any, of the Fair Market Value of the Shares
on the date of exercise over the Exercise Price.  The Company will be required
to withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income at the time of exercise.

          8.4  Disposition of Shares.  In the case of an NQSO, if Shares are
               ---------------------                                        
held for more than one year before disposition, any gain on disposition of the
Shares will be treated as long- term capital gain for federal and California
income tax purposes.  In the case of an ISO, if Shares are held for more than
one year after the date of exercise and more than two years after the Date of
Grant, any gain on disposition on the Shares will be treated as long-term
capital gain for federal and California income tax purposes.  If Shares acquired
pursuant to an ISO are disposed of within such one year or two year periods (a
"disqualifying disposition"), gain on such disqualifying disposition will be
- --------------------------                                                  
treated as compensation income (taxable at ordinary income rates) to the extent
of the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price (the "Spread"), or, if less, the difference
                                       ------                               
between the amount realized on the sale of such Shares and the Exercise Price.
Any gain in excess of the Spread shall be treated as capital gain.

rights of a shareholder with respect to any Shares until Optionee exercises the
Option and pays the Exercise Price.

warrants to the Company as follows:

(a)  Optionee has received, read and understood the Plan and the Grant and
     agrees to abide by and be bound by their terms and conditions.

(b)  Optionee is purchasing the Shares for Optionee's own account for investment
     purposes only and not with a view to, or for sale in connection with, a
     distribution of the Shares within the meaning of the Securities Act.

(c)  Optionee has no present intention of selling or otherwise disposing of all
     or any portion of the Shares.

(d)  Optionee is fully aware of the highly speculative nature of the investment
     in the Shares; the financial hazards involved; and the lack of liquidity of
     the Shares and the restrictions on transferability of the Shares (e.g.,
                                                                       ---- 
     that Optionee may not be able to sell or dispose of the Shares or use them

     has the ability to protect Optionee's own interests in this transaction and
     is financially capable of bearing a total loss of this investment.

     3.   COMPLIANCE WITH SECURITIES LAWS.  Optionee understands and
          -------------------------------
acknowledges that the Shares have not been registered under the Securities Act
and that, notwithstanding any other provision of the Grant to the contrary, the
exercise of any rights to purchase any Shares is expressly conditioned upon
compliance with the Securities Act and all applicable state securities laws.
Optionee agrees to cooperate with the Company to ensure compliance with such
laws. The Shares are being issued under the Securities Act pursuant to (the
Company will check the applicable box):

               [  ] the exemption provided by Rule 701;
               [  ] the exemption provided by Rule 504;
               [  ] Section 4(2) of the Securities Act;
               [  ] other:____________________________.

     4.   FEDERAL RESTRICTIONS ON TRANSFER.  Optionee understands that the
          --------------------------------
Shares must be held indefinitely unless they are registered under the Securities
Act or unless an exemption from such registration is available and that the

Company or any Parent, Subsidiary or Affiliate of the Company or if the
Committee determines that Optionee is rendering substantial services as a part-

assignees shall have the option to repurchase from Optionee (or from Optionee's
personal representative as the case may be) no less than all of the Shares at
the higher of Fair Market Value of such Shares on the Termination Date or the
Purchase Price per Share.  If the Repurchase Option of the Shares is assigned,
the assignee must pay the Company upon assignment cash equal to the difference
between the Purchase Price per Share and the Fair Market Value of the Shares
where the original Purchase Price is less than the Fair Market Value.

          9.4  Payment of Repurchase Price.  The repurchase price shall be

transfers and/or releases of such Shares as are in accordance with the terms of
this Exercise Agreement.  Optionee and the Company agree that Escrow Holder
shall not be liable to any party to this Exercise Agreement (or to any other
party) for any actions or omissions unless Escrow Holder is grossly negligent
relative thereto.  The Escrow Holder may rely upon any letter, notice or other
document executed by any signature purported to be genuine and may rely on
advice of counsel and obey any order of any court with respect to the
transactions contemplated herein.  The Shares shall be released from escrow upon
termination of both the Repurchase Option and the Right of First Refusal;

legend also be placed upon the share certificate(s) evidencing ownership of the
Shares:

     "IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY,

     CORPORATIONS OF THE STATE OF CALIFORNIA, EXCEPT AS PERMITTED IN THE
     COMMISSIONER'S RULES."

issue appropriate "stop-transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

CONSULTANT(S) OPTIONEE DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND THAT OPTIONEE IS NOT RELYING ON THE COMPANY FOR
ANY TAX ADVICE.  IN PARTICULAR, IF THE SHARES ARE SUBJECT TO REPURCHASE BY THE
COMPANY OR IF OPTIONEE IS AN INSIDER SUBJECT TO SECTION 16(b) OF THE EXCHANGE
ACT, OPTIONEE REPRESENTS THAT OPTIONEE HAS CONSULTED WITH OPTIONEE'S TAX
ADVISERS CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION WITH THE
INTERNAL REVENUE SERVICE.

as the Committee may impose.  At the discretion of the Committee, the Company
may reserve to itself and/or its assignee(s) in the Restricted Stock Purchase
Agreement (a) a right of first refusal to purchase all Shares that a Participant
(or a subsequent transferee) may propose to transfer to a third party and/or (b)
a right to repurchase a portion of or all Shares held by a Participant upon
Participant's termination of employment or service with the Company or a Parent,
Subsidiary or Affiliate of the Company, for any reason within a specified time
as determined by the Committee at the time of grant at Participant's original
purchase price or the Fair Market Value of such Shares.  In the case of a
reservation of a right to repurchase Shares under clause (b) above, (i) if the

cancellation of purchase money indebtedness for the Shares, and the right shall
terminate when the common stock of the Company become publicly traded; or (ii)

20% per year over 5 years from the date the Shares were purchased, which right
shall be exercisable within 90 days of termination of employment for cash or
cancellation of purchase money indebtedness for the Shares, and (B), if the
right is assignable, the assignee must pay the Company upon assignment of the
right cash equal to the difference between the original price and the Fair
Market Value if the original purchase price is less than the Fair Market Value.
The Committee may provide for the lapse of any restrictions in installments and
may accelerate the lapsing of such restrictions, or waive such restrictions, in
whole or part, based on length of service, performance or such other factors or
criteria as the Committee may determine.

     8.  ESCROW.  To enforce any restrictions on a Participant's Shares, the

Shares, together with stock powers or other instruments of transfer approved by
the Committee, appropriately endorsed in blank, with the Company or an agent
designated by the Company to hold in escrow until such restrictions have lapsed
or terminated, and the Committee may cause a legend or legends referencing such
restrictions to be placed on the certificates.

         9.1  Voting and Dividends.  No Participant shall have any of the rights
              --------------------

Participant.  After Shares are issued to the Participant, the Participant shall
be a shareholder and have all the rights of a shareholder with respect to such
Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company shall be subject to the same restrictions as
the Restricted Stock; provided, further, that the Participant shall have no
right to retain such stock dividends or stock distributions with respect to
Shares that are repurchased at the Participant's original Purchase Price
pursuant to Section 7.

Participant has Awards outstanding; provided, however, the Company shall not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

split, reverse stock split, recapitalization, combination, reclassification or
similar change in the capital structure of the Company without consideration, or

distributed, without consideration in a spin-off or similar transaction, to the
shareholders of the Company, the number of Shares available under this Plan

the Company is not the surviving corporation, a transaction in which 100% of the
then outstanding voting stock is sold or otherwise transferred, or any sale of
substantially all of the assets of the Company, the Company shall use its best
efforts to cause the successor to assume the Company's obligations under this
Plan or to provide a substantially similar plan to the Participants who have
purchased Shares under this Plan and who are employed by the successor.

approved by the shareholders of the Company, in any manner permitted by
applicable corporate law, within twelve months before or after the date this

may grant Awards pursuant to this Plan; provided that, in the event that
shareholder approval is not obtained within the time period provided herein, all
Shares issued pursuant to Awards granted hereunder shall be rescinded.  Such
Shares shall not be counted in determining whether such approval is obtained.
After the Company becomes subject to Section 16(b) of the Exchange Act, the
Company will comply with the requirements of Rule 16b-3 with respect to
shareholder approval.

     14. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award shall not be

state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed, as they are in effect on the date of grant of the
Award and also on the date of issuance of Shares.  Notwithstanding any other
provision in the Plan, the Company shall have no obligation to issue or deliver
certificates for Shares under the Plan prior to (a) obtaining any approvals from
governmental agencies that the Company determines are necessary or advisable,
and/or (b) completion of any registration or other qualification of such shares
under any state or federal law or ruling of any governmental body that the
Company determines to be necessary or advisable.  The Company shall be under no
obligation to register the Shares with the SEC or to effect compliance with the
registration, qualification or listing requirements of any state securities
laws, stock exchange or automated quotation system.

               ----------------------                                        
highly speculative nature of the investment in the Shares; (ii) the financial
hazards involved; (iii) the lack of liquidity of the Shares and the restrictions
on transferability of the Shares (e.g., that Purchaser may not be able to sell
                                  ----

acknowledges that, in reliance upon the representations and warranties made by
Purchaser herein, the Shares are not being registered with the Securities and
Exchange Commission ("SEC") under the 1933 Act or being qualified under the
                      ---                                                  
California Corporate Securities Law of 1968, as amended (the "Law"), but instead
                                                              ---

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

                                             Restricted Stock Purchase Agreement

the Company is under no obligation to do so with respect to the Shares.
Purchaser has also been advised that exemptions from registration and
qualification may not be available or may not permit Purchaser to transfer all
or any of the Shares in the amounts or at the times proposed by Purchaser.

          (H)  RULE 144.  In addition, Purchaser has been advised that SEC Rule
               --------                                                        
144 promulgated under the 1933 Act, which permits certain limited sales of
unregistered securities, is not presently available with respect to the Shares
and, in any event, requires that the Shares be held for a minimum of two years,
and in certain cases three years, after they have been purchased and paid for
                                                                 ------------
(within the meaning of Rule 144), before they may be resold under Rule 144.

          Purchaser understands that Shares paid for with a Note may not be
deemed to be fully "paid for" within the meaning of Rule 144 unless certain
conditions are met and that, accordingly, the Rule 144 holding period of such
Shares may not begin to run until such Shares are fully paid for within the
meaning of Rule 144. Purchaser understands that Rule 144 may indefinitely
restrict transfer of the Shares so long as Purchaser remains an "affiliate" of
the Company and "current public information" about the Company (as defined in
Rule 144) is not publicly available.

EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION
BEING AVAILABLE.

Holder's bona fide intention to sell or otherwise transfer the Offered Shares;

               ----------------------------------                            
(30) days after the date of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all (but not less than
all) of the Offered Shares proposed to be transferred to any one or more of the
Proposed Transferees named in the Notice, at the purchase price determined in

includes consideration other than cash, then the value of the non-cash
consideration as determined in good faith by the Company's Board of Directors
will conclusively be deemed to be the cash equivalent value of such non-cash
consideration.

          (D)  PAYMENT. Payment of the purchase price for Offered Shares will be
               -------  
payable, at the option of the Company and/or its assignee(s) (as applicable), by

Offered Shares by such assignee) or by any combination thereof. The purchase
price will be paid without interest within sixty (60) days after the Company's
receipt of the Notice, or, at the option of the Company and/or its assignee(s),

Holder may sell or otherwise transfer such Offered Shares to that Proposed
Transferee at the Offered Price or at a higher price, provided that such sale or

agrees in writing that the provisions of this Section will continue to apply to
the Offered Shares in the hands of such Proposed Transferee. If the Offered
Shares described in the Notice are not transferred to the Proposed Transferee

the Company will again be offered the Right of First Refusal before any Shares
held by the Holder may be sold or otherwise transferred.

releases of such Shares as are in accordance with the terms of this Agreement.
Purchaser and the Company agree that Escrow Holder will not be liable to any
party to this Agreement (or to any other party) for any actions or omissions
unless Escrow Holder is grossly negligent or intentionally fraudulent in
carrying out the duties of Escrow Holder under this Section. Escrow Holder may
rely upon any letter, notice or other document executed by any signature
purported to be genuine and may rely on the advice of counsel and obey any order
of any court with respect to the transactions contemplated by this Agreement.
The Shares will be released from escrow upon termination of both the Repurchase
Option and the Right of First Refusal, provided, however, that the Shares will

any, of the fair market value of the Vested Shares, at the time they cease to be
Unvested Shares, over the purchase price for such Shares. Purchaser represents
that Purchaser has consulted any tax consultant(s) Purchaser deems advisable in
connection with Purchaser's purchase of the Shares and the filing of the
election under Section 83(b) and similar tax provisions. A form of Election

 ----------                                                                     
deposited with and held by the Escrow Holder (as defined in the Purchase
Agreement) and that, notwithstanding anything to the contrary in the Purchase
Agreement, for purposes of carrying out the provisions of this Agreement, Escrow
Holder will act solely for the Company as its agent.

          2.   REPRESENTATIONS AND WARRANTIES.  Pledgor hereby represents and
               ------------------------------                                
warrants to the Company that Pledgor has good title (both record and beneficial)
to the Collateral, free and clear of all claims, pledges, security interests,
liens or encumbrances of every nature whatsoever, and that Pledgor has the right
to pledge and grant the Company the security interest in the Collateral granted

               -----------------                                             
Note) by Pledgor under the Note, the Company will have full power to sell,
assign and deliver the whole or any part of the Collateral at any broker's
exchange or elsewhere, at public or private sale, at the option of the Company,
in order to satisfy any part of the obligations of Pledgor now existing or
hereinafter arising under the Note. On any such sale, the Company or its assigns
may purchase all or any part of the Collateral. In addition, at its sole option,
the Company may elect to retain all the Collateral in full satisfaction of
Pledgor's obligation under the Note, in accordance with the provisions and
procedures set forth in the California Commercial Code.

          4.   ADDITIONAL REMEDIES.  The rights and remedies granted to the

Company herein upon default under the Note will be in addition to all the
rights, powers and remedies of the Company under the California Commercial Code
and applicable law and such rights, powers and remedies will be exercisable by
the Company with respect to all of the Collateral. Pledgor agrees that the
Company's reasonable expenses of holding the Collateral, preparing it for resale
or other disposition, and selling or otherwise disposing of the Collateral,
including attorneys' fees and other legal expenses, will be deducted from the
proceeds of any sale or other disposition and will be included in the amounts
Pledgor must tender to redeem the Collateral. All rights, powers and remedies of
the Company will be cumulative and not alternative. Any forbearance or failure
or delay by the Company in exercising any right, power or remedy hereunder will
not be deemed to be a waiver of any such right, power or remedy and any single
or partial exercise of any such right, power or remedy hereunder will not
preclude the further exercise thereof.

payable with respect to the Collateral during the term of this pledge (excluding
only ordinary cash dividends, which will be payable to Pledgor so long as
Pledgor is not in default under the Note) will be immediately delivered to the
Company to be held in pledge under this Agreement. Notwithstanding this
Agreement, so long as Pledgor owns the Shares and is not in default under the
Note, Pledgor will be entitled to vote any shares comprising the Collateral,
subject to any proxies granted by Pledgor.

          6.   ADJUSTMENTS.  In the event that during the term of this pledge,
               -----------                                                    
any stock dividend, reclassification, readjustment, stock split or other change
is declared or made with respect to the Collateral, or if warrants or any other
rights, options or securities are issued in respect of the Collateral, then all
new, substituted and/or additional shares or other securities issued by reason
of such change or by reason of the exercise of such warrants, rights, options or
securities, will be immediately pledged to the Company to be held under the
terms of this Agreement in the same manner as the Collateral is held hereunder.

          7.   RIGHTS UNDER PURCHASE AGREEMENT.  Pledgor understands and agrees

                          AS ADOPTED JANUARY 31, 1997
                          AS AMENDED OCTOBER 8, 1997


     1.   PURPOSE. The purpose of this Plan is to provide incentives to attract,
          -------  
retain and motivate eligible persons whose present and potential contributions
are important to the success of the Company, its Parent and Subsidiaries, by
offering them an opportunity to participate in the Company's future performance
through awards of Options and Restricted Stock.  Capitalized terms not defined
in the text are defined in Section 22.  This Plan is intended to be a written
compensatory benefit plan within the meaning of Rule 701 promulgated under the
Securities Act.

     2.   SHARES SUBJECT TO THE PLAN.
          -------------------------- 

          2.1  Number of Shares Available.  Subject to Sections 2.2 and 17, the
               --------------------------                                      
total number of Shares reserved and available for grant and issuance pursuant to
this Plan will be 6,600,000 Shares or such lesser number of Shares as permitted
under Section 260.140.45 of Title 10 of the California Code of Regulations.
Subject to Sections 2.2 and 17, Shares will again be available for grant and
issuance in connection with future Awards under this Plan that: (a) are subject
to issuance upon exercise of an Option but cease to be subject to such Option
for any reason other than exercise of such Option or (b) are subject to an Award
that otherwise terminates without Shares being issued.  At all times the Company
will reserve and keep available a sufficient number of Shares as will be
required to satisfy the requirements of all Awards granted under this Plan.

          2.2  Adjustment of Shares.  In the event that the number of
               --------------------                                  
outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the shareholders of the
Company and compliance with applicable securities laws; provided, however, that
                                                        --------  -------      
fractions of a Share will not be issued but will either be paid in cash at Fair
Market Value of such fraction of a Share or will be rounded up to the nearest
whole Share, as determined by the Committee.

     3.   ELIGIBILITY.  ISOs (as defined in Section 5 below) may be granted only
          -----------                                                           
to employees (including officers and directors who are also employees) of the
Company or of a Parent or Subsidiary of the Company.  All other Awards may be
granted to employees, officers, directors and consultants of the Company or any
Parent or Subsidiary of the Company; provided such consultants render bona fide
services not in connection with the offer and sale of securities in a capital-
raising transaction.  A person may be granted more than one Award under this
Plan.

               (b)  If the Participant is Terminated because of Participant's
                    death or Disability (or the Participant dies within three
                    (3) months after a Termination other than because of
                    Participant's death or Disability or Cause), then
                    Participant's Options may be exercised only to the extent

                    Termination Date (or such shorter time period, not less than
                    six (6) months, as may be specified in the Stock Option
                    Agreement) or such longer time period not exceeding five (5)

                    within the meaning of Section 22(e)(3) of the Code, or (b)
                    twelve (12) months after the Termination Date when the
                    Termination is for Participant's death or disability, within
                    the meaning of Section 22(e)(3) of the Code, deemed to be an
                    NQSO, but in any event no later than the expiration date of
                    the Options.

               (c)  If the Participant is terminated for Cause, then
                    Participant's options shall expire on such Participant's
                    Termination Date, or at such later time and on such

such minimum number will not prevent Participant from exercising the Option for
the full number of Shares for which it is then exercisable.

          5.8  Limitations on ISOs.  The aggregate Fair Market Value (determined
               -------------------                                              
as of the date of grant) of Shares with respect to which ISOs are exercisable
for the first time by a Participant during any calendar year (under this Plan or
under any other incentive stock option plan of the Company or any Parent or
Subsidiary of the Company) will not exceed $100,000.  If the Fair Market Value
of Shares on the date of grant with respect to which ISOs are exercisable for
the first time by a Participant during any calendar year exceeds $100,000, then
the Options for the first $100,000 worth of Shares to become exercisable in such
calendar year will be ISOs and the Options for the amount in excess of $100,000
that become exercisable in that calendar year will be NQSOs.  In the event that
the Code or the regulations promulgated thereunder are amended after the
Effective Date (as defined in Section 18 below) of this Plan to provide for a
different limit on the Fair Market Value of Shares permitted to be subject to
ISOs, then such different limit will be automatically incorporated herein and
will apply to any Options granted after the effective date of such amendment.

          5.9  Modification, Extension or Renewal.  The Committee may modify,
               ----------------------------------                            
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of a Participant, impair any of such Participant's rights under
any Option previously granted.  Any outstanding ISO that is modified, extended,
renewed or otherwise altered will be treated in accordance with Section 424(h)
of the Code.  The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
provided, however, that the Exercise Price may not be reduced below the minimum
- -------- --------                                                              
Exercise Price that would be permitted under Section 5.4 of this Plan for
Options granted on the date the action is taken to reduce the Exercise Price.

          5.10 No Disqualification.  Notwithstanding any other provision in
               -------------------                                         
this Plan, no term of this Plan relating to ISOs will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

     6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the Company
          ----------------                                                      
to sell to an eligible person Shares that are subject to restrictions. The
Committee will determine to whom an offer will be made, the number of Shares the
person may purchase, the Purchase Price, the restrictions to which the Shares
will be subject, and all other terms and conditions of the Restricted Stock
Award, subject to the following:

          6.1  Form of Restricted Stock Award.  All purchases under a Restricted
               ------------------------------                                   
Stock Award made pursuant to this Plan will be evidenced by an Award Agreement
("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form (which need
not be the same for each Participant) as the Committee will from time to time
approve, and will comply with and be subject to the terms and conditions of this
Plan.  The offer of Restricted Stock will be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full

payment for the Shares to the Company within thirty (30) days from the date the
Restricted Stock Purchase Agreement is delivered to the person.  If such person
does not execute and deliver the Restricted Stock Purchase Agreement along with
full payment for the Shares to the Company within thirty (30) days, then the
offer will terminate, unless otherwise determined by the Committee.

          6.2  Purchase Price.  The Purchase Price of Shares sold pursuant to a
               --------------                                                  
Restricted Stock Award will be determined by the Committee and will be at least
85% of the Fair Market Value of the Shares on the date the Restricted Stock
Award is granted or at the time the purchase is consummated, except in the case
of a sale to a Ten Percent Shareholder, in which case the Purchase Price will be
100% of the Fair Market Value on the date the Restricted Stock Award is granted
or at the time the purchase is consummated.  Payment of the Purchase Price may
be made in accordance with Section 7 of this Plan.

          6.3  Restrictions.  Restricted Stock Awards may be subject to the
               ------------                                                
restrictions set forth in Section 11 of this Plan or such other restrictions not
inconsistent with Section 25102(o) of the California Corporations Code.

     7.   PAYMENT FOR SHARE PURCHASES.
          --------------------------- 

          7.1  Payment.  Payment for Shares purchased pursuant to this Plan may
               -------                                                         
be made in cash (by check) or, where expressly approved for the Participant by
the Committee and where permitted by law:

               (a)  by cancellation of indebtedness of the Company to the
                    Participant;

               (b)  by surrender of shares that either: (I) have been owned by
                    Participant for more than six (6) months and have been paid
                    for within the meaning of SEC Rule 144 (and, if such shares
                    were purchased from the Company by use of a promissory note,
                    such note has been fully paid with respect to such shares);
                    or (2) were obtained by Participant in the public market;

               (c)  by tender of a full recourse promissory note having such
                    terms as may be approved by the Committee and bearing
                    interest at a rate sufficient to avoid imputation of income
                    under Sections 483 and 1274 of the Code; provided, however,
                                                             --------  ------- 
                    that Participants who are not employees or directors of the
                    Company will not be entitled to purchase Shares with a
                    promissory note unless the note is adequately secured by
                    collateral other than the Shares;

               (d)  by waiver of compensation due or accrued to the Participant
                    for services rendered;

               (e)  with respect only to purchases upon exercise of an Option,

                    (1)  through a "same day sale" commitment from the
                         Participant and a broker-dealer that is a member of the
                         National Association of Securities Dealers (an "NASD
                         DEALER") whereby the Participant irrevocably elects to
                         exercise the Option and to sell a portion of the Shares
                         so purchased to pay for the Exercise Price, and whereby
                         the NASD Dealer irrevocably commits upon receipt of
                         such Shares to forward the Exercise Price directly to
                         the Company; or

                    (2)  through a "margin" commitment from the Participant and
                         an NASD Dealer whereby the Participant irrevocably
                         elects to exercise the Option and to pledge the Shares
                         so purchased to the NASD Dealer in a margin account as
                         security for a loan from the NASD Dealer in the amount
                         of the Exercise Price, and whereby the NASD Dealer
                         irrevocably commits upon receipt of such Shares to
                         forward the Exercise Price directly to the Company; or

               (f)  by any combination of the foregoing.

          7.2  Loan Guarantees.  The Committee may help the Participant pay for
               ---------------                                                 
Shares purchased under this Plan by authorizing a guarantee by the Company of a
third-party loan to the Participant.

     8.   WITHHOLDING TAXES.
          ----------------- 

          8.1  Withholding Generally.  Whenever Shares are to be issued in
               ---------------------                                      
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

          8.2  Stock Withholding.  When, under applicable tax laws, a
               -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee for such elections and be in writing in a form
acceptable to the Committee.

     9.   PRIVILEGES OF STOCK OWNERSHIP.

          9.1  Voting and Dividends.  No Participant will have any of the rights
               --------------------                                             
of a shareholder with respect to any Shares until the Shares are issued to the
Participant.  After Shares are issued to the Participant, the Participant will
be a shareholder and have all the rights of a shareholder with respect to such
Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
                                                        --------              
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Unvested
Shares that are repurchased pursuant to Section 11.  The Company will comply
with Section 260.140.1 of the California Corporations Code with respect to the
voting rights of Common Stock.

          9.2  Financial Statements.  The Company will provide financial
               --------------------                                     
statements to each Participant prior to such Participant's purchase of Shares
under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding, or as otherwise required or permitted under
Section 260.140.46 of Title 10 of the California Code of Regulations.
Notwithstanding the foregoing, the Company will not be required to provide such
financial statements to Participants whose services in connection with the
Company assure them access to equivalent information.

     10.  TRANSFERABILITY.  Awards granted under this Plan, and any interest
          ---------------                                                   
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution.  During the lifetime of the
Participant an Award will be exercisable only by the Participant, and any
elections with respect to an Award, may be made only by the Participant.

     11.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
          ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Award Agreement (a)
a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, unless
otherwise not permitted by Section 25102(o) of the California Corporations Code,
provided, that such right of first refusal terminates when the Company's
- --------                                                                
securities become publicly traded and/or (b) a right to repurchase Shares held
by a Participant following such Participant's Termination at any time within
ninety (90) days after Participant's Termination Date (or, in the case of
securities issued upon exercise of an Option after the Participant's Termination
Date, within 90 days after the date of such exercise) for cash and/or
cancellation of purchase money indebtedness, at: (A) with respect to Vested
Shares, the Fair Market Value of such Shares on Participant's Termination Date,
provided, that such right of repurchase terminates when the Company's securities
- --------                                                                        
become publicly traded; or (B) with respect to Unvested Shares, the
Participant's Exercise Price or Purchase Price, as the case may be, provided,
                                                                    -------- 
that to the extent the Participant is not an officer, director or consultant of
the Company or of a Parent or Subsidiary of the Company, such right of
repurchase at the Exercise Price or Purchase Price, as the case may be, lapses
at the rate of at least twenty percent (20%) per year over five (5) years from:
(i) the date of grant of the Option or (ii) in the case of Restricted Stock, the
date the Participant purchases the Shares.

     12.  CERTIFICATES.  All certificates for Shares or other securities
          ------------                                                  
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

     13.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
          ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
                                   --------  -------                        
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

     14.  EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or from
          -----------------------------                                         
time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

     15.  SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  This Plan is intended
          ----------------------------------------------                        
to comply with Section 25102(o) of the California Corporations Code.  Any
provision of the Plan which is inconsistent with Section 25102(o) shall, without
further act or amendment by the Company or the Board, be reformed to comply with
the requirements of Section 25102(o).  An Award will not be effective unless
such Award is in compliance with all applicable federal and state securities
laws, rules and regulations of any governmental body, and the requirements of
any stock exchange or automated quotation system upon which the Shares may then
be listed or quoted, as they are in effect on the date of grant of the Award and
also on the date of exercise or other issuance.  Notwithstanding any other
provision in this Plan, the Company will have no obligation to issue or deliver
certificates for Shares under this Plan prior to (a) obtaining any approvals
from governmental agencies that the Company determines are necessary or
advisable, and or (b) compliance with any exemption, completion of any
registration or other qualification of such Shares under any state or federal
law or ruling of any governmental body that the Company determines to be
necessary or advisable.  The Company will be under no obligation to register the
Shares with the SEC or to effect compliance with the exemption,

registration, qualification or listing requirements of any state securities
laws, stock exchange or automated quotation system, and the Company will have no
liability for any inability or failure to do so.

     16.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award granted
          -----------------------                                            
under this Plan will confer or be deemed to confer on any Participant any right
to continue in the employ of, or to continue any other relationship with, the
Company or any Parent or Subsidiary of the Company or limit in any way the right
of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

     17.  CORPORATE TRANSACTIONS.
          ---------------------- 

          17.1  Assumption or Replacement of Awards by Successor.  In the event
                ------------------------------------------------               
of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
                                                                     ----- ----
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the shareholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the shareholders of the Company immediately prior to such merger
(other than any shareholder which merges, or which owns or controls another
corporation which merges, with the Company in such merger) cease to own their
shares or other equity interests in the Company, or (d) the sale of
substantially all of the assets of the Company, any or all outstanding Awards
may be assumed, converted or replaced by the successor corporation (if any),
which assumption, conversion or replacement will be binding on all Participants.
In the alternative, the successor corporation may substitute equivalent Awards
or provide substantially similar consideration to Participants as was provided
to shareholders (after taking into account the existing provisions of the
Awards).  The successor corporation may also issue, in place of outstanding
Shares of the Company held by the Participant, substantially similar shares or
other property subject to repurchase restrictions and other provisions no less
favorable to the Participant than those which applied to such outstanding Shares
immediately prior to such transaction described in this Subsection 16.1.  In the
event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 16.1, then notwithstanding any other provision in this Plan to the
contrary, such Awards will expire on such transaction at such time and on such

granting an Award under this Plan in substitution of such other company's award
or (b) assuming such award as if it had been granted under this Plan if the
terms of such assumed award could be applied to an Award granted under this
Plan.  Such substitution or assumption will be permissible if the holder of the
substituted or assumed award would have been eligible to be granted an Award
under this Plan if the other company had applied the rules of this Plan to such
grant.  In the event the Company assumes an award granted by another company,

be approved by the shareholders of the Company (excluding Shares issued pursuant
to this Plan), consistent with applicable laws, within twelve (12) months before
or after the Effective Date.  Upon the Effective Date, the Board may grant
Awards pursuant to this Plan; provided, however, that no Option may be exercised

approval is not obtained within twelve (12) months before or after the date this
Plan is adopted by the Board, all Awards granted hereunder will be canceled, any
Shares issued pursuant to any Award will be canceled and any purchase of Shares
hereunder will be rescinded.

     19.  TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as provided
          --------------------------

shareholders of the Company, amend this Plan in any manner that requires such
shareholder approval pursuant to the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans.

               4.3    Payment.  The Exercise Agreement shall be accompanied by
                      -------
full payment of the Exercise Price for the shares being purchased in cash (by
check), or where permitted by law:

          (a)  by cancellation of indebtedness of the Company to the
               Participant;

          (b)  by surrender of shares of the Company's Common Stock that either:
               (1) have been owned by Participant for more than six (6) months
               and have been paid for within the meaning of SEC Rule 144 (and,
               if such shares were purchased from the Company by use of a
               promissory note, such note has been fully paid with respect to
               such shares); or (2) were obtained by Participant in the open
               public market; and (3) are clear of all liens, claims,
               encumbrances or security interests;

          (c)  by waiver of compensation due or accrued to Participant for
               services rendered;

          (d)  provided that a public market for the Company's stock exists, (1)
               through a "same day sale" commitment from Participant and a
               broker-dealer that is a member of the National Association of
               Securities Dealers (an "NASD DEALER") whereby Participant
               irrevocably elects to exercise the Option and to sell a portion
               of the Shares so purchased to pay for the Exercise Price and
               whereby the NASD Dealer irrevocably commits upon receipt of such
               Shares to forward the Exercise Price directly to the Company, or
                                                                             --
               (2) through a "margin" commitment from Participant and an NASD
               Dealer whereby Participant irrevocably elects to exercise the
               Option and to pledge the Shares so purchased to the NASD Dealer
               in a margin account as security for a loan from the NASD Dealer
               in the amount of the Exercise Price, and whereby the NASD Dealer
               irrevocably commits upon receipt of such Shares to forward the
               Exercise Price directly to the Company; or

          (e)  by any combination of the foregoing.

               4.4    Tax Withholding.  Prior to the issuance of the Shares upon
                      ---------------                                           
exercise of the Option, Participant must pay or provide for any applicable
federal, state and local withholding obligations of the Company.  If the
Committee permits, Participant may provide for payment of withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld.  In
such case, the Company shall issue the net number of Shares to the Participant
by deducting the Shares retained from the Shares issuable upon exercise.

               4.5    Issuance of Shares.  Provided that the Exercise Agreement
                      ------------------
and payment are in form and substance satisfactory to counsel for the Company,
the Company shall issue the Shares registered in the name of Participant,
Participant's authorized assignee, or Participant's legal representative, and
shall deliver certificates representing the Shares with the appropriate legends
affixed thereto.

          5.   NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the Option
               -------------------------------------------------                
is an ISO, and if Participant sells or otherwise disposes of any of the Shares
acquired pursuant to the ISO on or before the later of (a) the date two (2)
years after the Date of Grant, and (b) the date one (1) year after transfer of
such Shares to Participant upon exercise of the Option, Participant shall
immediately notify the Company in writing of such disposition.  Participant
agrees that Participant may be subject to income tax withholding by the Company
on the compensation income recognized by Participant from the early disposition
by payment in cash or out of the current wages or other compensation payable to
Participant.

          6.   COMPLIANCE WITH LAWS AND REGULATIONS.  The Plan and this
               ------------------------------------
Agreement are intended to comply with Section 25102(o) of the California
Corporations Code. Any provision of this Agreement which is inconsistent with
Section 25102(o) shall, without further act or amendment by the Company or the
Board, be reformed to comply with the requirements of Section 25102(o). The
exercise of the Option and the issuance and transfer of Shares shall be subject
to compliance by the Company and Participant with all applicable requirements of

                                       3
<PAGE>
 
federal and state securities laws and with all applicable requirements of any
stock exchange on which the Company's Common Stock may be listed at the time of
such issuance or transfer. Participant understands that the Company is under no
obligation to register or qualify the Shares with the Securities and Exchange
Commission, any state securities commission or any stock exchange to effect such
compliance.

          7.   NONTRANSFERABILITY OF OPTION.  The Option may not be transferred
               ----------------------------                                    
in any manner other than by will or by the laws of descent and distribution and
may be exercised during the lifetime of Participant only by Participant.  The
terms of the Option shall be binding upon the executors, administrators,
successors and assigns of Participant.

          8.   INTENTIONALLY OMITTED.
               --------------------- 

          9.   COMPANY'S RIGHT OF FIRST REFUSAL.  Unvested Shares may not be
               --------------------------------
sold or otherwise transferred by Participant without the Company's prior written
consent. Before any Vested Shares held by Participant or any transferee of such
Vested Shares (either being sometimes referred to herein as the "Holder") may be
                                                                 ------
sold or otherwise transferred (including without limitation a transfer by gift
or operation of law), the Company and/or its assignee(s) shall have an
assignable right of first refusal to purchase the Vested Shares to be sold or
transferred (the "Offered Shares") on the terms and conditions set forth in this
                  --------------
Section (the "Right of First Refusal").
              ----------------------

               9.1    Notice of Proposed Transfer.  The Holder of the Offered
                      ---------------------------                            
Shares shall deliver to the Company a written notice (the "Notice") stating:
                                                           ------            
(i) the Holder's bona fide intention to sell or otherwise transfer the Offered
Shares; (ii) the name of each proposed bona fide purchaser or other transferee
("Proposed Transferee"); (iii) the number of Offered Shares to be transferred to
  -------------------                                                           
each Proposed Transferee; (iv) the bona fide cash price or other consideration
for which the Holder proposes to transfer the Offered Shares (the "Offered
                                                                   -------
Price"); and (v) that the Holder will offer to sell the Offered Shares to the
- -----
Company and/or its assignee(s) at the Offered Price as provided in this Section.

               9.2    Exercise of Right of First Refusal.  At any time within
                      ----------------------------------                     
thirty (30) days after the date of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase the
Offered Shares proposed to be transferred to any one or more of the Proposed
Transferees named in the Notice, at the purchase price determined as specified
below.

               9.3    Purchase Price.  The purchase price for the Offered Shares
                      --------------                                            
purchased under this Section will be the Offered Price.  If the Offered Price
includes consideration other than cash, then the cash equivalent value of the
non-cash consideration shall conclusively be deemed to be the value of such non-
cash consideration as determined in good faith by the Company's Board of
Directors.

               9.4    Payment.  Payment of the purchase price for Offered Shares
                      -------                                                   
will be payable, at the option of the Company and/or its assignee(s) (as
applicable), by check or by cancellation of all or a portion of any outstanding
indebtedness of the Holder to the Company (or to such assignee, in the case of a
purchase of Offered Shares by such assignee) or by any combination thereof.  The
purchase price will be paid without interest within sixty (60) days after the
Company's receipt of the Notice, or, at the option of the Company and/or its
assignee(s), in the manner and at the time(s) set forth in the Notice.

               9.5    Holder's Right to Transfer.  If all of the Offered Shares
                      --------------------------                               
proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Offered Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided that
                                                               --------     
such sale or other transfer is consummated within 120 days after the date of the
Notice, and provided further, that (i) any such sale or other transfer is
            -------- -------                                             
effected in compliance with all applicable securities laws and (ii) the Proposed
Transferee agrees in writing that the provisions of this Section will continue
to apply to the Offered Shares in the hands of such Proposed Transferee.  If the
Offered Shares described in the Notice are not transferred to the Proposed
Transferee within such 120 day period, then a new Notice must be given to the
Company, and the Company will again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

               9.6    Exempt Transfers.  Notwithstanding anything to the
                      ----------------
contrary in this Section, the following transfers of Vested Shares will be
exempt from the Right of First Refusal: (i) the transfer of any or all of the
Vested Shares during Participant's lifetime by gift or on Participant's death by
will or intestacy to Participant's "immediate family" (as defined below) or to a
trust for the benefit of Participant or Participant's immediate family, provided
that each transferee or other recipient agrees in a writing satisfactory to the
Company that the provisions of this Section will continue to apply to the
transferred Vested Shares in the hands of such transferee or other recipient;
(ii) any transfer of Vested Shares made pursuant to a statutory merger or
statutory consolidation of the Company with or into another corporation or
corporations (except that the Right of First Refusal and Repurchase Option will
continue to apply thereafter to such Vested Shares, in which case the surviving
corporation of such merger or consolidation shall succeed to the rights of the
Company under this Section unless the agreement of merger or consolidation
expressly otherwise provides); or (iii) any transfer of Vested Shares pursuant
to the winding up and dissolution of the Company. As used herein, the term
"immediate family" will mean Participant's spouse, the lineal descendant or
 ----------------
antecedent, father, mother, brother or sister, adopted child or grandchild of
the Participant or the Participant's spouse, or the spouse of any child, adopted
child, grandchild or adopted grandchild of Participant or the Participant's
spouse.

               9.7    Termination of Right of First Refusal.  The Company's
                      -------------------------------------
Right of First Refusal will terminate when the Company's securities become
publicly traded.

          10.  TAX CONSEQUENCES.  Set forth below is a brief summary as of the
               ----------------                                               
Effective Date of the Plan of some of the federal and California tax
consequences of exercise of the Option and disposition of the Shares.  THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.  PARTICIPANT SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE
OPTION OR DISPOSING OF THE SHARES.

               10.1   Exercise of ISO.  If the Option qualifies as an ISO, there
                      ---------------                                           
will be no regular federal or California income tax liability upon the exercise
of the Option, although the excess, if any, of the Fair Market Value of the
Shares on the date of exercise over the Exercise Price will be treated as a tax
preference item for federal income tax purposes and may subject the Participant
to the alternative minimum tax in the year of exercise.

               10.2   Exercise of Nonqualified Stock Option.  If the Option does
                      -------------------------------------                     
not qualify as an ISO, there may be a regular federal and California income tax
liability upon the exercise of the Option.  Participant will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the Fair Market Value of the Shares on the date of
exercise over the Exercise Price.  If Participant is or was an employee of the
Company, the Company will be required to withhold from Participant's
compensation or collect from Participant and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

               10.3   Disposition of Shares.  If the Shares are held for more
                      ---------------------
than twelve (12) months after the date of the transfer of the Shares pursuant to
the exercise of the Option for Vested Shares and, in the case of an ISO, are
disposed of more than two years after the Date of Grant, any gain realized on
disposition of the Shares will be treated as long term capital gain for federal
and California income tax purposes. If Shares purchased under an ISO are
disposed of within the applicable one year or two year period, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the excess, if any, of the Fair Market Value of
the Shares on the date of exercise over the Exercise Price. The Company may be
required to withhold from Participant's compensation or collect from Participant
and pay to the applicable taxing authorities an amount equal to a percentage of
this compensation income at the time of exercise.

          11.  PRIVILEGES OF STOCK OWNERSHIP.  Participant shall not have any of
               -----------------------------                                    
the rights of a shareholder with respect to any Shares until the Shares are
issued to Participant.

          12.  INTERPRETATION.  Any dispute regarding the interpretation of this
               --------------                                                   
Agreement shall be submitted by Participant or the Company to the Committee for
review.  The resolution of such a dispute by the Committee shall be final and
binding on the Company and Participant.

          13.  ENTIRE AGREEMENT.  The Plan is incorporated herein by reference.
               ----------------                                                 
This Agreement and the Plan constitute the entire agreement of the parties and
supersede all prior undertakings and agreements with respect to the subject
matter hereof.

          14.  NOTICES.  Any notice required to be given or delivered to the
               -------                                                      
Company under the terms of this Agreement shall be in writing and addressed to
the Corporate Secretary of the Company at its principal corporate offices.  Any
notice required to be given or delivered to Participant shall be in writing and
addressed to Participant at the address indicated above or to such other address
as such party may designate in writing from time to time to the Company.  All
notices shall be deemed to have been given or delivered upon:  personal
delivery; three (3) days after deposit in the United States mail by certified or
registered mail (return receipt requested); one (1) business day after deposit
with any return receipt express courier (prepaid); or one (1) business day after
transmission by facsimile, rapifax or telecopier.

          15.  SUCCESSORS AND ASSIGNS.  The Company may assign any of its rights
               ----------------------                                           
under this Agreement including its rights to repurchase Shares under the
Repurchase Option and the Right of First Refusal.  This Agreement shall be
binding upon and inure to the benefit of the successors and assigns of the
Company.  Subject to the restrictions on transfer set forth herein, this
Agreement shall be binding upon Participant and Participant's heirs, executors,
administrators, legal representatives, successors and assigns.

          16.  GOVERNING LAW.  This Agreement shall be governed by and construed
               -------------                                                    
in accordance with the laws of the State of California as such laws are applied
to agreements between California residents entered into and to be performed
entirely within California.  If any provision of this Agreement is determined by
a court of law to be illegal or unenforceable, then such provision will be
enforced to the maximum extent possible and the other provisions will remain
fully effective and enforceable.

          17.  ACCEPTANCE.  Participant hereby acknowledges receipt of a copy of
               ----------                                                       
the Plan and this Agreement.  Participant has read and understands the terms and
provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and this Agreement.  Participant acknowledges that there
may be adverse tax consequences upon exercise of the Option or disposition of
the Shares and that Participant should consult a tax adviser prior to such
exercise or disposition.

        IN WITNESS WHEREOF, the Company has caused this Agreement to be executed
in duplicate by its duly authorized representative and Participant has executed
this Agreement in duplicate as of the Date of Grant.

                 3.1   Agrees to Terms of the Plan.  Purchaser has received a
                       ---------------------------

disposing of all or any portion of the Shares and no one other than Purchaser

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

assets, liabilities and financial condition that Purchaser reasonably considers
important in making the decision to purchase the Shares, and Purchaser has had
ample opportunity to ask questions of the Company's representatives concerning
such matters and this investment.

              3.4   Understanding of Risks.  Purchaser is fully aware of:  (i)
                    ----------------------                                    
the highly speculative nature of the investment in the Shares; (ii) the
financial hazards involved; (iii) the lack of liquidity of the Shares and the
restrictions on transferability of the Shares (e.g., that Purchaser may not be
                                               ----                           
able to sell or dispose of the Shares or use them as collateral for loans); (iv)
the qualifications and backgrounds of the management of the Company; and (v) the
tax consequences of investment in the Shares.  Purchaser is capable of

with the offer, sale and purchase of the Shares.

          4.  COMPLIANCE WITH SECURITIES LAWS.
              ------------------------------- 

              4.1   Compliance with Federal Securities Laws.  Purchaser
                    ---------------------------------------            
understands and acknowledges that the Shares have not been registered with the
Securities and Exchange Commission ("SEC") under the Securities Act and that,
                                     ---                                     
notwithstanding any other provision of the Stock Option Agreement to the
contrary, the exercise of any rights to purchase any Shares is expressly
conditioned upon compliance with the Securities Act and all applicable state
securities laws.  Purchaser agrees to cooperate with the Company to ensure
compliance with such laws.  The Shares are being issued under the Securities Act
pursuant to the exemption provided by SEC Rule 701.

              4.2   Compliance with California Securities Laws.  THE PLAN, THE
                    ------------------------------------------

REQUIREMENTS OF SECTION 25102(o).  THE SALE OF THE SECURITIES THAT ARE THE
SUBJECT OF THIS EXERCISE AGREEMENT, IF NOT YET QUALIFIED WITH THE CALIFORNIA
COMMISSIONER OF CORPORATIONS AND NOT EXEMPT FROM SUCH QUALIFICATION, IS SUBJECT
TO SUCH QUALIFICATION, AND THE ISSUANCE OF SUCH SECURITIES, AND THE RECEIPT OF
ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL
UNLESS THE SALE IS EXEMPT.  THE RIGHTS OF THE PARTIES TO THIS EXERCISE AGREEMENT
ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION
BEING AVAILABLE.

          5.  RESTRICTED SECURITIES.
              --------------------- 

              5.1   No Transfer Unless Registered or Exempt.  Purchaser
                    ---------------------------------------            
understands that Purchaser may not transfer any Shares unless such Shares are
registered under the Securities Act or qualified under applicable state
securities laws or unless, in the opinion of counsel to the Company, exemptions
from such registration and qualification requirements are available.  Purchaser
understands that only the Company may file a registration statement with the SEC
and that the Company is under no obligation to do so with respect to the Shares.
Purchaser has also been advised that exemptions from registration and
qualification may not be available or may not permit Purchaser to transfer all
or any of the Shares in the amounts or at the times proposed by Purchaser.

SEC Rule 144 promulgated under the Securities Act, which permits certain limited

Shares and, in any event, requires that the Shares be held for a minimum of two
years, and in certain cases three years, after they have been purchased and paid
                                                                        --------

"affiliate" of the Company or if "current public information" about the Company
(as defined in Rule 144) is not publicly available.

taken; and

                    (d)  Purchaser shall have provided the Company with written

transferred Shares are subject to (i) both the Company's Repurchase Option and
the Company's Right of First Refusal granted hereunder and (ii) the market

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

for which the Holder proposes to transfer the Offered Shares (the "Offered
                                                                   -------

Company and/or its assignee(s) at the Offered Price as provided in this Section.

              9.2   Exercise of Right of First Refusal.  At any time within
                    ----------------------------------

assignee(s) may, by giving written notice to the Holder, elect to purchase the
Offered Shares proposed to be transferred to any one or more of the Proposed
Transferees named in the Notice, at the purchase price determined as specified

purchased under this Section will be the Offered Price.  If the Offered Price
includes consideration other than cash, then the cash equivalent value of the
non-cash consideration shall conclusively be deemed to be the value of such non-
cash consideration as determined in good faith by the Company's Board of
Directors.

              9.4   Payment.  Payment of the purchase price for Offered Shares
                    -------

applicable), by check or by cancellation of all or a portion of any outstanding
indebtedness of the Holder to the Company (or to such assignee, in the case of a
purchase of Offered Shares by such assignee) or by any combination thereof.  The
purchase price will be paid without interest within sixty (60) days after the
Company's receipt of the Notice, or, at the option of the Company and/or its
assignee(s), in the manner and at the time(s) set forth in the Notice.

              9.5   Holder's Right to Transfer.  If all of the Offered Shares

purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Offered Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided that

effected in compliance with all applicable securities laws and (ii) the Proposed
Transferee agrees in writing that the provisions of this Section will continue
to apply to the Offered Shares in the hands of such Proposed Transferee.  If the
Offered Shares described in the Notice are not transferred to the Proposed
Transferee within such 120 day period, then a new Notice must be given to the
Company, and the Company will again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

              9.6   Exempt Transfers.  Notwithstanding anything to the contrary
                    ----------------

Refusal and Repurchase Option will continue to apply thereafter to such Vested
Shares, in which case the surviving corporation of such merger or consolidation
shall succeed to the rights of the Company under this Section unless the
agreement of merger or consolidation expressly otherwise provides); or (iii) any
transfer of Vested Shares pursuant to the winding up and dissolution of the
Company. As used herein, the term "immediate family" will mean Purchaser's

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

traded.

          10. RIGHTS AS SHAREHOLDER.  Subject to the terms and conditions of
              ---------------------

of the Company with respect to the Shares from and after the date that Shares
are issued to Purchaser until such time as Purchaser disposes of the Shares or
the Company and/or its assignee(s) exercise(s) the Repurchase Option or Right of
First Refusal.  Upon an exercise of the Repurchase Option or the Right of First
Refusal, Purchaser will have no further rights as a holder of the Shares so
purchased upon such exercise, except the right to receive payment for the Shares
so purchased in accordance with the provisions of this Exercise Agreement, and
Purchaser will promptly surrender the stock certificate(s) evidencing the Shares
so purchased to the Company for transfer or cancellation.

          11. ESCROW.  As security for Purchaser's faithful performance of this
              ------                                                           
Agreement, Purchaser agrees, immediately upon receipt of the stock
certificate(s) evidencing the Shares, to deliver such certificate(s), together
with the Stock Powers executed by Purchaser and by Purchaser's spouse, if any
(with the date and number of Shares left blank), to the Secretary of the Company
or other designee of the Company ("Escrow Holder"), who is hereby appointed to
                                   -------------                              
hold such certificate(s) and Stock Powers in escrow and to take all such actions
and to effectuate all such transfers and/or releases of such Shares as are in
accordance with the terms of this Agreement.  Purchaser and the Company agree
that Escrow Holder will not be liable to any party to this Exercise Agreement
(or to any other party) for any actions or omissions unless Escrow Holder is
grossly negligent or intentionally fraudulent in carrying out the duties of
Escrow Holder under this Exercise Agreement.  Escrow Holder may rely upon any
letter, notice or other document executed by any signature purported to be
genuine and may rely on the advice of counsel and obey any order of any court
with respect to the transactions contemplated by this Agreement.  The Shares
will be released from escrow upon termination of both the Repurchase Option and
the Right of First Refusal.

                    -------

          THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO
          RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED
          OR RESOLD EXCEPT AS PERMITTED UNDER THE SECURITIES ACT AND APPLICABLE

          TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN
          COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
          LAWS. THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
          CERTAIN RESTRICTIONS ON PUBLIC RESALE AND TRANSFER, RIGHT OF
          REPURCHASE AND RIGHT OF FIRST REFUSAL OPTIONS HELD BY THE ISSUER
          AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION EXERCISE
          AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES,
          A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER.
          SUCH PUBLIC SALE AND TRANSFER RESTRICTIONS AND THE RIGHT OF REPURCHASE
          AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

          The California Commissioner of Corporations may require that the
following legend also be placed upon the share certificate(s) evidencing
ownership of the Shares:

          IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY, OR
          ANY INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR,
          WITHOUT THE PRIOR WRITTEN CONSENT OF THE COMMISSIONER OF CORPORATIONS
          OF THE STATE OF CALIFORNIA, EXCEPT AS PERMITTED IN THE COMMISSIONER'S
          RULES.

              12.2  Stop-Transfer Instructions.  Purchaser agrees that, to
                    --------------------------              
ensure compliance with the restrictions imposed by this Agreement, the Company
may issue appropriate "stop-transfer" instructions to its transfer agent, if
any, and if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

              12.3  Refusal to Transfer.  The Company will not be required (i)
                    -------------------

owner of such Shares, or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares have been so transferred.

          13. TAX CONSEQUENCES.  PURCHASER UNDERSTANDS THAT PURCHASER MAY
              ----------------   
SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER'S PURCHASE OR
DISPOSITION OF THE SHARES. PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED
WITH ANY TAX ADVISER PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE
OR DISPOSITION OF THE SHARES AND THAT PURCHASER IS NOT RELYING ON THE COMPANY
FOR ANY TAX ADVICE. IN PARTICULAR, IF UNVESTED SHARES ARE SUBJECT TO REPURCHASE
BY THE COMPANY, PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH
PURCHASER'S TAX ADVISER CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION
WITH THE INTERNAL REVENUE SERVICE. Set forth below is a brief summary as of the
date the Plan was adopted by the Board of some of the federal and California tax
consequences of exercise of the Option and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE. PURCHASER SHOULD CONSULT A TAX ADVISER BEFORE EXECUTING THIS OPTION
OR DISPOSING OF THE SHARES.

              13.1  Exercise of Incentive Stock Option.  If the Option qualifies
                    ----------------------------------                          
as an incentive stock option, there will be no regular federal income tax
liability or California income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as a tax preference item for
federal income tax purposes and may subject Purchaser to the alternative minimum
tax in the year of exercise.

              13.2  Exercise of Nonqualified Stock Option.  If the Option does
                    -------------------------------------                     
not qualify as an incentive stock option, there may be a regular federal income
tax liability and a California income tax liability upon the exercise of the
Option.  Purchaser will be treated as having received compensation income
(taxable at

ordinary income tax rates) equal to the excess, if any, of the Fair Market Value
of the Shares on the date of exercise over the Exercise Price. If Purchaser is
or was an employee of the Company, the Company will be required to withhold from
Purchaser's compensation or collect from Purchaser and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

              13.3  Disposition of Shares.  If the Shares are held for more than
                    ---------------------                                       
twelve (12) months after the date of the acquisition of the Shares pursuant to
the exercise of the Option for Vested Shares and, in the case of an ISO, are
disposed of more than two years after the Date of Grant, any gain realized on
disposition of the Shares will be treated as long term capital gain for federal
and California income tax purposes. If Shares purchased under an ISO are
disposed of within the applicable one year or two year period, any gain realized
on such disposition will be treated as compensation income (taxable at ordinary
income rates) to the extent of the excess, if any, of the Fair Market Value of
the Shares on the date of exercise over the Exercise Price. The Company may be
required to withhold from Purchaser's compensation or collect from Purchaser and
pay to the applicable taxing authorities an amount equal to a percentage of this
compensation income at the time of exercise.

          14. COMPLIANCE WITH LAWS AND REGULATIONS.  The issuance and transfer
              ------------------------------------                            
of the Shares will be subject to and conditioned upon compliance by the Company
and Purchaser with all applicable state and federal laws and regulations and
with all applicable requirements of any stock exchange or automated quotation
system on which the Company's Common Stock may be listed or quoted at the time
of such issuance or transfer.

          15. SUCCESSORS AND ASSIGNS.  The Company may assign any of its rights
              ----------------------                                           
under this Agreement, including its rights to repurchase Shares under the
Repurchase Option and the Right of First Refusal.  This Agreement shall be
binding upon and inure to the benefit of the successors and assigns of the
Company.  Subject to the restrictions on transfer herein set forth, this
Agreement will be binding upon Purchaser and Purchaser's heirs, executors,
administrators, legal representatives, successors and assigns.

          16. GOVERNING LAW; SEVERABILITY.  This Agreement shall be governed by
              ---------------------------                                      
and construed in accordance with the internal laws of the State of California as
such laws are applied to agreements between California residents entered into
and to be performed entirely within California.  If any provision of this
Agreement is determined by a court of law to be illegal or unenforceable, then
such provision will be enforced to the maximum extent possible and the other
provisions will remain fully effective and enforceable.

          17. NOTICES.  Any notice required to be given or delivered to the
              -------

included for ease of reference only and will be disregarded in interpreting or

                         As Adopted January 15, 1998


         1.   PURPOSE.  The purpose of this Plan is to provide incentives to
              -------                                                       
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses.  Capitalized terms not defined in the text are defined in Section 23.

         2.   SHARES SUBJECT TO THE PLAN.
              -------------------------- 

              2.1  Number of Shares Available.  Subject to Sections 2.2 and 18,
                   --------------------------

granted under the Prior Plan but cease to be subject to such option for any
reason other than exercise of such option; and (c) shares that were issued under

or forfeited. Subject to Sections 2.2 and 18, Shares that are subject to: (x)
issuance upon exercise of an Option but cease to be subject to such Option for
any reason other than exercise of such Option; (y) an Award granted hereunder
but are forfeited or are repurchased by the Company at the original issue price;
and (z) an Award that otherwise terminates without Shares being issued, will
again be available for grant and issuance in connection with future Awards under
this Plan. At all times the Company shall reserve and keep available a
sufficient number of Shares as shall be required to satisfy the requirements of
all outstanding Options granted under this Plan and all other outstanding but
unvested Awards granted under this Plan.

              2.2  Adjustment of Shares.  In the event that the number of

split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,

Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
                                                        --------  -------      
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.

         3.   ELIGIBILITY.  ISOs (as defined in Section 5 below) may be granted
              -----------                                                      
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the

              4.2   Committee Discretion.  Any determination made by the
                    --------------------                                
Committee with respect to any Award will be made in its sole discretion at the
time of grant of the Award or, unless in contravention of any express term of
this Plan or Award, at any later time, and such determination will be final and
binding on the Company and on all persons having an interest in any Award under
this Plan.  The Committee may delegate to one or more officers of the Company
the authority to grant an Award under this Plan to Participants who are not
Insiders of the Company.

         5.   OPTIONS.  The Committee may grant Options to eligible persons and
              -------                                                          
will determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOS"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

              5.1   Form of Option Grant.  Each Option granted under this Plan
                    --------------------                                      
will be evidenced by an Award Agreement which will expressly identify the Option
as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in such form and
contain such provisions (which need not be the same for each Participant) as the
Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

              5.2   Date of Grant.  The date of grant of an Option will be the
                    -------------                                             
date on which the Committee makes the determination to grant such Option, unless
otherwise specified by the Committee.  The Stock Option Agreement and a copy of
this Plan will be delivered to the Participant within a reasonable time after
the

granting of the Option.

              5.3   Exercise Period. Options may be exercisable within the times
                    ---------------
or upon the events determined by the Committee as set forth in the Stock Option
Agreement governing such Option; provided, however, that no Option will be
                                 --------  -------
exercisable after the expiration of ten (10) years from the date the Option is
granted; and provided further that no ISO granted to a person who directly or by
             -------- -------
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration of
five (5) years from the date the ISO is granted. The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

              5.4   Exercise Price.  The Exercise Price of an Option will be
                    --------------                                          
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will be not less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a Ten Percent Stockholder will not be less than 110% of the Fair
Market Value of the Shares on the date of grant.  Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

              5.5   Method of Exercise.  Options may be exercised only by
                    ------------------                                   
delivery to the Company of a written stock option exercise agreement  (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

              5.6   Termination.  Notwithstanding the exercise periods set forth
                    -----------                                                 
in the Stock Option Agreement, exercise of an Option will always be subject to
the following:

         (a)  If the Participant is Terminated for any reason except death or
              Disability, then the Participant may exercise such Participant's
              Options only to the extent that such Options would have been
              exercisable upon the Termination Date no later than three (3)
              months after the Termination Date (or such shorter or longer time
              period not exceeding five (5) years as may be determined by the
              Committee, with any exercise beyond three (3) months after the
              Termination Date deemed to be an NQSO), but in any event, no later
              than the expiration date of the Options.

         (b)  If the Participant is Terminated because of Participant's death or
              Disability (or the Participant dies within three (3) months after
              a Termination other than for Cause or because of Participant's
              Disability), then Participant's Options may be exercised only to
              the extent that such Options would have been exercisable by
              Participant on the Termination Date and must be exercised by
              Participant (or Participant's legal representative or authorized
              assignee) no later than twelve (12) months after the Termination
              Date (or such shorter or longer time period not exceeding five (5)
              years as may be determined by the Committee, with any such
              exercise beyond (a) three (3) months after the Termination Date
              when the Termination is for any reason other than the
              Participant's death or Disability, or (b) twelve (12) months after
              the Termination Date when the Termination is for Participant's
              death or

              Disability, deemed to be an NQSO), but in any event no later than
              the expiration date of the Options.

         (c)  Notwithstanding the provisions in paragraph 5.6(a) above, if a
              Participant is terminated for Cause, neither the Participant, the
              Participant's estate nor such other person who may then hold the
              Option shall be entitled to exercise any Option with respect to
              any Shares whatsoever, after termination of service, whether or
              not after termination of service the Participant may receive
              payment from the Company or Subsidiary for vacation pay, for
              services rendered prior to termination, for services rendered for
              the day on which termination occurs, for salary in lieu of notice,
              or for any other benefits.  In making such determination, the
              Board shall give the Participant an opportunity to present to the
              Board evidence on his behalf.  For the purpose of this paragraph,
              termination of service shall be deemed to occur on the date when
              the Company dispatches notice or advice to the Participant that
              his service is terminated.

              5.7   Limitations on Exercise.  The Committee may specify a
                    -----------------------                              
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

              5.8   Limitations on ISO.  The aggregate Fair Market Value
                    ------------------                                  
(determined as of the date of grant) of Shares with respect to which ISO are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) will not exceed $100,000.  If the Fair Market
Value of Shares on the date of grant with respect to which ISO are exercisable
for the first time by a Participant during any calendar year exceeds $100,000,
then the Options for the first $100,000 worth of Shares to become exercisable in
such calendar year will be ISO and the Options for the amount in excess of
$100,000 that become exercisable in that calendar year will be NQSOs.  In the
event that the Code or the regulations promulgated thereunder are amended after
the Effective Date of this Plan to provide for a different limit on the Fair
Market Value of Shares permitted to be subject to ISO, such different limit will
be automatically incorporated herein and will apply to any Options granted after
the effective date of such amendment.

              5.9   Modification, Extension or Renewal.  The Committee may
                    ----------------------------------                    
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted.  Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code.  The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; provided, however, that the Exercise Price may not be reduced
                --------  -------                                            
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

              5.10  No Disqualification.  Notwithstanding any other provision in
                    -------------------                                         
this Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

         6.   RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
              ----------------                                              
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

              6.1   Form of Restricted Stock Award.  All purchases under a
                    ------------------------------                        
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT")

                                                      1998 Equity Incentive Plan


that will be in such form (which need not be the same for each Participant) as
the Committee will from time to time approve, and will comply with and be
subject to the terms and conditions of this Plan.  The offer of Restricted Stock
will be accepted by the Participant's execution and delivery of the Restricted
Stock Purchase Agreement and full payment for the Shares to the Company within
thirty (30) days from the date the Restricted Stock Purchase Agreement is
delivered to the person.  If such person does not execute and deliver the
Restricted Stock Purchase Agreement along with full payment for the Shares to
the Company within thirty (30) days, then the offer will terminate, unless
otherwise determined by the Committee.

              6.2   Purchase Price.  The Purchase Price of Shares sold pursuant
                    --------------                                             
to a Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value.  Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

              6.3   Terms of Restricted Stock Awards.  Restricted Stock Awards
                    --------------------------------                          
shall be subject to such restrictions as the Committee may impose.  These
restrictions may be based upon completion of a specified number of years of
service with the Company or upon completion of the performance goals as set out
in advance in the Participant's individual Restricted Stock Purchase Agreement.
Restricted Stock Awards may vary from Participant to Participant and between
groups of Participants.  Prior to the grant of a Restricted Stock Award, the
Committee shall:  (a) determine the nature, length and starting date of any
Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant.  Prior to
the payment of any Restricted Stock Award, the Committee shall determine the
extent to which such Restricted Stock Award has been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Restricted Stock Awards that are subject to different Performance Periods and
having different performance goals and other criteria.

              6.4   Termination During Performance Period.  If a Participant is
                    -------------------------------------                      
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

         7.   STOCK BONUSES.
              ------------- 

              7.1   Awards of Stock Bonuses. A Stock Bonus is an award of Shares
                    -----------------------   
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company. A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan. A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.
          
              7.2   Terms of Stock Bonuses.  The Committee will determine the
                    ----------------------                                   
number of Shares to be awarded to the Participant.  If the Stock Bonus is being
earned upon the satisfaction of performance goals pursuant to a Performance
Stock Bonus Agreement, then the Committee will: (a)  determine the nature,
length and starting date of any Performance Period for each Stock Bonus; (b)
select from among the Performance Factors to be used to measure the performance,
if any; and (c) determine the number of Shares that may be awarded to the
Participant.  Prior to the payment of any Stock Bonus, the Committee shall
determine the extent to which such Stock Bonuses have been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to

                                                    1998 Equity Incentive Plan


Stock Bonuses that are subject to different Performance Periods and different
performance goals and other criteria.  The number of Shares may be fixed or may
vary in accordance with such performance goals and criteria as may be determined
by the Committee.  The Committee may adjust the performance goals applicable to
the Stock Bonuses to take into account changes in law and accounting or tax
rules and to make such adjustments as the Committee deems necessary or
appropriate to reflect the impact of extraordinary or unusual items, events or
circumstances to avoid windfalls or hardships.

              7.3   Form of Payment.  The earned portion of a Stock Bonus may be
                    ---------------                                             
paid currently or on a deferred basis with such interest or dividend equivalent,
if any, as the Committee may determine.  Payment may be made in the form of cash
or whole Shares or a combination thereof, either in a lump sum payment or in
installments, all as the Committee will determine.

         8.   PAYMENT FOR SHARE PURCHASES.
              --------------------------- 

              8.1      Payment. Payment for Shares purchased pursuant to this
                       -------
Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

         (a)  by cancellation of indebtedness of the Company to the Participant;

         (b)  by surrender of shares that either:  (1) have been owned by
              Participant for more than six (6) months and have been paid for
              within the meaning of SEC Rule 144 (and, if such shares were
              purchased from the Company by use of a promissory note, such note
              has been fully paid with respect to such shares); or (2) were
              obtained by Participant in the public market;

         (c)  by tender of a full recourse promissory note having such terms as
              may be approved by the Committee and bearing interest at a rate

              employees or directors of the Company will not be entitled to
              purchase Shares with a promissory note unless the note is
              adequately secured by collateral other than the Shares;

         (d)  by waiver of compensation due or accrued to the Participant for
              services rendered;

         (e)  with respect only to purchases upon exercise of an Option, and
              provided that a public market for the Company's stock exists:

              (1)  through a "same day sale" commitment from the Participant and
                   a broker-dealer that is a member of the National Association
                   of Securities Dealers (an "NASD DEALER") whereby the
                   Participant irrevocably elects to exercise the Option and to
                   sell a portion of the Shares so purchased to pay for the
                   Exercise Price, and whereby the NASD Dealer irrevocably
                   commits upon receipt of such Shares to forward the Exercise
                   Price directly to the Company; or

              (2)  through a "margin" commitment from the Participant and a NASD
                   Dealer whereby the Participant irrevocably elects to exercise
                   the Option and to pledge the Shares so purchased to the NASD
                   Dealer in a margin account as security for a loan from the
                   NASD Dealer in the amount of the Exercise Price, and whereby
                   the NASD Dealer irrevocably commits upon receipt of such
                   Shares to forward the Exercise Price directly to the Company;
                   or

         9.   WITHHOLDING TAXES.
              ----------------- 

              9.1   Withholding Generally.  Whenever Shares are to be issued in
                    ---------------------                                      
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

              9.2   Stock Withholding.  When, under applicable tax laws, a
                    -----------------                                     
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee

         10.  PRIVILEGES OF STOCK OWNERSHIP.
              ----------------------------- 

              10.1  Voting and Dividends.  No Participant will have any of the
                    --------------------                                      
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant.  After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
                                                        --------              
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
                  --------  -------                                            
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

              10.2  Financial Statements.  The Company will provide financial
                    --------------------                                     
statements to each Participant prior to such Participant's purchase of Shares
under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
                                    --------  -------                         
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

         11.  TRANSFERABILITY.  Awards granted under this Plan, and any interest
              ---------------                                                   
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution or as determined by the Committee and
set forth in the Award Agreement with respect to Awards that are not ISOs.
During the lifetime of the Participant an Award will be exercisable only by the
Participant, and any elections with respect to an Award may be made only by the
Participant unless otherwise determined by the Committee and set forth in the
Award Agreement with respect to Awards that are not ISOs.

         12.  RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
              ----------------------                                          
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or

cancellation of purchase money indebtedness, at the Participant's Exercise Price
or Purchase Price, as the case may be.

         13.  CERTIFICATES.  All certificates for Shares or other securities
              ------------                                                  
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

         14.  ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
              ------------------------                                   
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
                                   --------  -------                        
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

         15.  EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
              -----------------------------                                    
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

         16.  SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award will not
              ----------------------------------------------                    
be effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable.  The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

         17.  NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award
              -----------------------                                    
granted under this Plan will confer or be deemed to confer on any Participant
any right to continue in the employ of, or to continue any other relationship
with, the Company or any Parent or Subsidiary of the Company or limit in any way
the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

         18.  CORPORATE TRANSACTIONS.
              ---------------------- 

              18.1  Assumption or Replacement of Awards by Successor.  In the
                    ------------------------------------------------         
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to such merger
(other than any stockholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale, or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, any or all outstanding Awards may be assumed, converted or
replaced by the successor corporation (if any), which assumption, conversion or
replacement will be binding on all Participants.  In the alternative, the
successor corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders (after
taking into account the existing provisions of the Awards).  The successor
corporation may also issue, in place of outstanding Shares of the Company held
by the Participant, substantially similar shares or other property subject to
repurchase restrictions no less favorable to the Participant.  In the event such
successor corporation (if any) refuses to assume or substitute Awards, as
provided above, pursuant to a transaction described in this Subsection 18.1,
such Awards will expire on such transaction at such time and on such conditions
as the Committee will determine; provided, however, that the Committee may, in
                                 --------  -------                            
its sole discretion, provide that the vesting of any or all Awards granted
pursuant to this Plan will accelerate.  If the Committee exercises such
discretion with respect to Options, such Options will become exercisable in full
prior to the consummation of such event at such time and on such conditions as
the Committee determines, and if such Options are not exercised prior to the
consummation of the corporate transaction, they shall terminate at such time as
determined by the Committee.

              18.2  Other Treatment of Awards.  Subject to any greater rights
                    -------------------------                                
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, or sale of assets.

              18.3  Assumption of Awards by the Company.  The Company, from time
                    -----------------------------------                         
to time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan.  Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant.  In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
- -------                                                                     
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code).  In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

         19.  ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become
              ---------------------------------                        
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "EFFECTIVE
DATE").  This Plan shall be approved by the stockholders of the Company
(excluding Shares issued pursuant to this Plan), consistent with applicable
laws, within twelve (12) months before or after the date this Plan is adopted by
the Board.  Upon the Effective Date, the Committee may grant Awards pursuant to
this Plan; provided, however, that: (a) no Option may be exercised prior to
           --------  -------                                               
initial stockholder approval of this Plan; (b) no Option granted pursuant to an
increase in the number of Shares subject to this Plan approved by the Board will
be exercised prior to the time such

increase has been approved by the stockholders of the Company; and (c) in the
event that stockholder approval of such increase is not obtained within the time
period provided herein, all Awards granted pursuant to such increase will be
canceled, any Shares issued pursuant to any Award granted pursuant to such
increase will be canceled, and any purchase of Shares pursuant to such increase
will be rescinded.

is adopted by the Board or, if earlier, the date of stockholder approval. This
Plan and all agreements thereunder shall be governed by and construed in

terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval

of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

         22.   NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by
               --------------------------                                       
the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

                    ----------

               4.2  Limitations on Exercise.  This Option may not be exercised
                    -----------------------

or state withholding obligations of the Company.  If the Committee permits,
Optionee may provide for payment of withholding taxes upon exercise of this

Company shall issue the net number of Shares to the Optionee by deducting the
Shares retained from the Shares issuable upon exercise.

               4.5  Issuance of Shares. Provided that the Exercise Agreement and

this Option is an ISO, if Optionee sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (a) the date two
(2) years after the Date of Grant, and (b) the date one (1) year after transfer
of such Shares to Optionee upon exercise of this Option, then Optionee shall
immediately notify the Company in writing of such disposition.

          6.   COMPLIANCE WITH LAWS AND REGULATIONS. The exercise of this Option
               ------------------------------------

Company and Optionee with all applicable requirements of federal and state
securities laws and with all applicable requirements of any stock exchange on

register or qualify the Shares with the SEC, any state securities commission or
any stock exchange to effect such compliance.

          7.   NONTRANSFERABILITY OF OPTION.  This Option may not be transferred
               ----------------------------                                     
in any manner other than by will or by the laws of descent and distribution and
may be exercised during the lifetime of Optionee only by Optionee.  The terms of

assigns of Optionee.

               ----------------                                               
date the Board adopted the Plan of some of the federal and California tax
consequences of exercise of this Option and disposition of the Shares.  THIS
SUMMARY IS NECESSARILY INCOMPLETE,

AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT
A TAX ADVISOR BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

               8.1  Exercise of Incentive Stock Option.  To the extent this
                    ----------------------------------                     
Option qualifies as an ISO, there will be no regular federal or California
income tax liability upon the exercise of this Option, although the excess, if
any, of the fair market value of the Shares on the date of exercise over the
Exercise Price will be treated as a tax preference item for federal income tax
purposes and may subject the Optionee to the alternative minimum tax in the year
of exercise.

               8.2  Exercise of Nonqualified Stock Option.  To the extent this
                    -------------------------------------                     
Option does not qualify as an ISO, there may be a regular federal and California
income tax liability upon the exercise of this Option.  Optionee will be treated
as having received compensation income (taxable at ordinary income tax rates)
equal to the excess, if any, of the fair market value of the Shares on the date
of exercise over the Exercise Price.  The Company may be required to withhold
from Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

               8.3  Disposition of Shares.  The following tax consequences may
                    ---------------------                                     
apply upon disposition of the Shares.

                    a.   Incentive Stock Options.  If the Shares are held for
                         -----------------------                             
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as capital gain for federal and California income tax purposes. The
maximum federal capital gain tax rates are twenty eight percent (28%) for Shares
held more than twelve (12) months, but not more than eighteen (18) months ("MID-
TERM CAPITAL GAIN"), and twenty percent (20%) for Shares held for more than
eighteen (18) months ("LONG-TERM CAPITAL GAIN").  If Shares purchased under an
ISO are disposed of within the applicable one (1) year or two (2) year period,
any gain realized on such disposition will be treated as compensation income
(taxable at ordinary income rates) to the extent of the excess, if any, of the
fair market value of the Shares on the date of exercise over the Exercise Price.

                    b.   Nonqualified Stock Options.  If the Shares are held for
                         --------------------------                             
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the
Shares will be treated as Mid-Term Capital Gain or Long-Term Capital Gain, as
the case may be.

                    c.   Withholding.  The Company may be required to withhold
                         -----------                                          
from Participant's compensation or collect from the Participant and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

                          EXODUS COMMUNICATIONS, INC.
                                        
                       1998 DIRECTORS STOCK OPTION PLAN
                                        
                         As Adopted January 15, 1998



     1.   PURPOSE.  This 1998 Directors Stock Option Plan (this "PLAN") is
established to provide equity incentives for certain nonemployee members of the
Board of Directors of Exodus Communications, Inc. (the "COMPANY"), who are
described in Section 6.1 below, by granting such persons options to purchase
shares of stock of the Company.

     2.   ADOPTION AND STOCKHOLDER APPROVAL.  After this Plan is adopted by the
Board of Directors of the Company (the "BOARD"), this Plan will become effective
on the time and date (the "EFFECTIVE DATE") on which the registration statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), to register the
initial public offering of the Company's Common Stock is declared effective by
the SEC.  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months after the date this
Plan is adopted by the Board.

     3.   TYPES OF OPTIONS AND SHARES.  Options granted under this Plan shall be
non-qualified stock options ("NQSOS").  The shares of stock that may be
purchased upon exercise of Options granted under this Plan (the "SHARES") are
shares of the Common Stock of the Company.

     4.   NUMBER OF SHARES.  The maximum number of Shares that may be issued
pursuant to Options granted under this Plan (the "MAXIMUM NUMBER") is 200,000
Shares, subject to adjustment as provided in this Plan. If any Option is
terminated for any reason without being exercised in whole or in part, the
Shares thereby released from such Option shall be available for purchase under
other Options subsequently granted under this Plan. At all times during the term
of this Plan, the Company shall reserve and keep available such number of Shares
as shall be required to satisfy the requirements of outstanding Options granted
under this Plan; provided, however that if the aggregate number of Shares
subject to outstanding Options granted under this Plan plus the aggregate number
of Shares previously issued by the Company pursuant to the exercise of Options
granted under this Plan equals or exceeds the Maximum Number, then
notwithstanding anything herein to the contrary, no further Options may be
granted under this Plan until the Maximum Number is increased or the aggregate
number of Shares subject to outstanding Options granted under this Plan plus the
aggregate number of Shares previously issued by the Company pursuant to the
exercise of Options granted under this Plan is less than the Maximum Number.

     5.   ADMINISTRATION.  This Plan shall be administered by the Board or
by a committee of not less than two members of the Board appointed to administer
this Plan (the "COMMITTEE").  As used in this Plan, references to the Committee
shall mean either such Committee or the Board if no Committee has been
established.  The interpretation by the Committee of any of the provisions of
this Plan or any Option granted under this Plan shall be final and binding upon
the Company and all persons having an interest in any Option or any Shares
purchased pursuant to an Option.

     6.   ELIGIBILITY AND AWARD FORMULA.

          6.1  Eligibility.  Options shall be granted only to directors of the
               -----------                                                    
Company who are not employees of the Company or any Parent, Subsidiary or
Affiliate of the Company, as those terms are defined in Section 18 below (each
such person referred to as an "OPTIONEE").

          6.2  Initial Grant.  Each Optionee who on or after the Effective Date
               -------------                                                   
first becomes a member of the Board will automatically be granted an Option for

the Board.

Company outside this Plan if such Optionee was ineligible to receive an Initial
Grant) provided the Optionee is a member of the Board on such date and has
served continuously as a member of the Board since the date of such Optionee's
Initial Grant or previous grant, as the case may be, the Optionee will
automatically be granted an Option for 5,000 Shares (a "SUCCEEDING GRANT").

imposed on the Shares and such representations and agreements regarding the
Optionee's investment intent and access to information as may be required by the

of the exercise price for the number of Shares being purchased.

          8.3  Payment.  Payment for the Shares purchased upon exercise of an
               -------                                                       
Option may be made (a) in cash or by check; (b) by surrender of shares of Common
Stock of the Company that have been owned by the Optionee for more than six (6)
months (and which have been paid for within the meaning of SEC Rule 144 and, if
such shares were purchased from the Company by use of a promissory note, such
note has been fully paid with respect to such shares) or were obtained by the
Optionee in the open public market, having a Fair Market Value equal to the
exercise price of the Option; (c) by waiver of compensation due or accrued to
the Optionee for services rendered; (d) provided that a public market for the
Company's stock exists, through a "same day sale" commitment from the Optionee
and a broker-dealer that is a member of the National Association of Securities
Dealers (an "NASD DEALER") whereby the Optionee irrevocably elects to exercise
the Option and to sell a portion of the Shares so purchased to pay for the
exercise price and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the exercise price directly to the Company; (e) provided
that a public market for the Company's stock exists, through a "margin"
commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably
elects to exercise the Option and to pledge the Shares so purchased to the NASD
Dealer in a margin account as security for a loan from the NASD Dealer in the
amount of the exercise price, and whereby the NASD Dealer irrevocably commits
upon receipt of such Shares to forward the exercise price directly to the
Company; or (f) by any combination of the foregoing.

          8.4  Withholding Taxes.  Prior to issuance of the Shares upon exercise
               -----------------                                                
of an Option, the Optionee shall pay or make adequate provision for any federal
or state withholding obligations of the Company, if applicable.

          8.5  Limitations on Exercise.  Notwithstanding the exercise periods
               -----------------------                                       
set forth in the Grant, exercise of an Option shall always be subject to the
following limitations:

               (a)  An Option shall not be exercisable unless such exercise is
in compliance with the Securities Act and all applicable state securities laws,
as they are in effect on the date of exercise.

               (b)  The Committee may specify a reasonable minimum number of
Shares that may be purchased upon any exercise of an Option, provided that such
minimum number will not prevent the Optionee from exercising the full number of
Shares as to which the Option is then exercisable.

     9.   NONTRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, an
Option shall be exercisable only by the Optionee or by the Optionee's guardian
or legal representative, unless otherwise determined by the Committee. No Option
may be sold, pledged, assigned, hypothecated, transferred or disposed of in any
manner other than by will or by the laws of descent and distribution, unless
otherwise determined by the Committee.

     10.  PRIVILEGES OF STOCK OWNERSHIP.  No Optionee shall have any of the
rights of a stockholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
the date of exercise, except as provided in this Plan.  The Company shall
provide to each Optionee a copy of the annual financial statements of the
Company at such time after the close of each fiscal year of the Company as they
are released by the Company to its stockholders.

     11.  ADJUSTMENT OF OPTION SHARES.  In the event that the number of
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per share of such outstanding
Options shall be proportionately adjusted, subject to any required action by the

issued upon exercise of any Option and any resulting fractions of a Share shall
be rounded up to the nearest whole Share.


     12.  NO OBLIGATION TO CONTINUE AS DIRECTOR. Nothing in this Plan or any
Option granted under this Plan shall confer on any Optionee any right to
continue as a director of the Company.

     13.  COMPLIANCE WITH LAWS.  The grant of Options and the issuance of
Shares upon exercise of any Options shall be subject to and conditioned upon
compliance with all applicable requirements of law, including without limitation
compliance with the Securities Act, compliance with all other applicable state
securities laws and compliance with the requirements of any stock exchange or
national market system on which the Shares may be listed.  The Company shall be
under no obligation to register the Shares with the SEC or to effect compliance
with the registration or qualification requirement of any state securities laws,
stock exchange or national market system.

     14.  ACCELERATION OF OPTIONS ON CERTAIN CORPORATE TRANSACTIONS. In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Options granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption, conversion or
replacement will be binding on all Optionees), (c) a merger in which the Company
is the surviving corporation but after which the stockholders of the Company
(other than any stockholder which merges (or which owns or controls another
corporation which merges) with the Company in such merger) cease to own their
shares or other equity interests in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, the vesting of all options granted pursuant to this Plan
will accelerate and the options will become exercisable in full prior to the
consummation of such event at such times and on such conditions as the Committee
determines, and must be exercised, if at all, within six months of the
consummation of said event. Any options not exercised within such six-month
period shall expire.

     15.  AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate
or amend this Plan or any outstanding option, provided that the Board may not
terminate or amend the terms of any outstanding option without the consent of
the Optionee. In any case, no amendment of this Plan may adversely affect any
then outstanding Options or any unexercised portions thereof without the written
consent of the Optionee.

     16.  TERM OF PLAN. Options may be granted pursuant to this Plan from time
to time within a period of ten (10) years from the Effective Date.

have the following meanings:

          17.1  "PARENT" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if each of such

                          EXODUS COMMUNICATIONS, INC.
                                        
                       1998 EMPLOYEE STOCK PURCHASE PLAN

                         As Adopted January 15, 1998


     1.   ESTABLISHMENT OF PLAN.  Exodus Communications, Inc. (the "COMPANY")
proposes to grant options for purchase of the Company's Common Stock to eligible
employees of the Company and its Participating Subsidiaries (as hereinafter
defined) pursuant to this Employee Stock Purchase Plan (this "PLAN"). For
purposes of this Plan, "PARENT CORPORATION" and "SUBSIDIARY" (collectively,
"PARTICIPATING SUBSIDIARIES") shall have the same meanings as "parent
corporation" and "subsidiary corporation" in Sections 424(e) and 424(f),
respectively, of the Internal Revenue Code of 1986, as amended (the "CODE").
"PARTICIPATING SUBSIDIARIES" are Parent Corporations or Subsidiaries that the
Board of Directors of the Company (the "BOARD") designates from time to time as
corporations that shall participate in this Plan. The Company intends this Plan
to qualify as an "employee stock purchase plan" under Section 423 of the Code
(including any amendments to or replacements of such Section), and this Plan
shall be so construed. Any term not expressly defined in this Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein. A
total of 600,000 shares of the Company's Common Stock is reserved for issuance
under this Plan. Such number shall be subject to adjustments effected in
accordance with Section 14 of this Plan.

     2.   PURPOSE.  The purpose of this Plan is to provide eligible employees of
the Company and Participating Subsidiaries with a convenient means of acquiring
an equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.

     3.   ADMINISTRATION.  This Plan shall be administered by the Compensation
Committee of the Board (the "COMMITTEE"). Subject to the provisions of this Plan
and the limitations of Section 423 of the Code or any successor provision in the
Code, all questions of interpretation or application of this Plan shall be
determined by the Committee and its decisions shall be final and binding upon
all participants. Members of the Committee shall receive no compensation for
their services in connection with the administration of this Plan, other than
standard fees as established from time to time by the Board for services
rendered by Board members serving on Board committees. All expenses incurred in
connection with the administration of this Plan shall be paid by the Company.

     4.   ELIGIBILITY.  Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:

          (a)  employees who are customarily employed for twenty (20) hours or
less per week;

          (b)  employees who are customarily employed for five (5) months or
less in a calendar year;

          (c)  employees who, together with any other person whose stock would
be attributed to such employee pursuant to Section 424(d) of the Code, own stock
or hold options to purchase stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or
any of its Participating Subsidiaries or who, as a result of being granted an
option under this Plan with respect to such Offering Period, would own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries; and

          (d)  individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors who are reclassified as
common law employees for any reason except for federal income and employment tax
                                    ------ ---                                  
purposes.

     5.   Offering Dates.  The offering periods of this Plan (each, an "OFFERING
PERIOD") shall be of twenty-four (24) months duration commencing on May 1 and
November 1 of each year and ending on April 30 and October 31 of each year;
provided, however, that notwithstanding the foregoing, the first such Offering
- --------  -------                                                             
Period shall commence

                                                     Exodus Communications, Inc.
                                               1998 Employee Stock Purchase Plan

on the first business day on which price quotations for the Company's Common
Stock are available on the Nasdaq National Market (the "FIRST OFFERING DATE")
and shall end on April 30, 2000. Each Offering Period shall consist of four (4)
six month purchase periods (individually, a "PURCHASE PERIOD") during which
payroll deductions of the participants are accumulated under this Plan. The
first Offering Period shall consist of no more than five and no fewer than three
Purchase Periods, any of which may be greater or less than six months as
determined by the Committee. The first business day of each Offering Period is
referred to as the "OFFERING DATE". The last business day of each Purchase
Period is referred to as the "PURCHASE DATE". The Committee shall have the power
to change the duration of Offering Periods with respect to offerings without
stockholder approval if such change is announced at least fifteen (15) days
prior to the scheduled beginning of the first Offering Period to be affected.

     6.   PARTICIPATION IN THIS PLAN. Eligible employees may become participants
in an Offering Period under this Plan on the first Offering Date after
satisfying the eligibility requirements by delivering a subscription agreement
to the Company's treasury department (the "TREASURY DEPARTMENT") not later than
five (5) days before such Offering Date. Notwithstanding the foregoing, the
Committee may set a later time for filing the subscription agreement authorizing
payroll deductions for all eligible employees with respect to a given Offering
Period. An eligible employee who does not deliver a subscription agreement to
the Treasury Department by such date after becoming eligible to participate in
such Offering Period shall not participate in that Offering Period or any
subsequent Offering Period unless such employee enrolls in this Plan by filing a
subscription agreement with the Treasury Department not later than five (5) days
preceding a subsequent Offering Date. Once an employee becomes a participant in
an Offering Period, such employee will automatically participate in the Offering
Period commencing immediately following the last day of the prior Offering
Period unless the employee withdraws or is deemed to withdraw from this Plan or
terminates further participation in the Offering Period as set forth in Section
11 below. Such participant is not required to file any additional subscription
agreement in order to continue participation in this Plan.

     7.   GRANT OF OPTION ON ENROLLMENT.  Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of Common Stock of the Company
determined by dividing (a) the amount accumulated in such employee's payroll
deduction account during such Purchase Period by (b) the lower of (i) eighty-
five percent (85%) of the fair market value of a share of the Company's Common
Stock on the Offering Date (but in no event less than the par value of a share
of the Company's Common Stock), or (ii) eighty-five percent (85%) of the fair
market value of a share of the Company's Common Stock on the Purchase Date (but
in no event less than the par value of a share of the Company's Common Stock),
provided, however, that the number of shares of the Company's Common Stock 
- --------  -------                                                          
subject to any option granted pursuant to this Plan shall not exceed the lesser
of (x) the maximum number of shares set by the Committee pursuant to Section
10(c) below with respect to the applicable Purchase Date, or (y) the maximum
number of shares which may be purchased pursuant to Section 10(b) below with
respect to the applicable Purchase Date. The fair market value of a share of the
Company's Common Stock shall be determined as provided in Section 8 below.

     8.   PURCHASE PRICE.  The purchase price per share at which a share of
Common Stock will be sold in any Offering Period shall be eighty-five percent
(85%) of the lesser of:

          (a)  The fair market value on the Offering Date; or

          (b)  The fair market value on the Purchase Date.

          For purposes of this Plan, the term "FAIR MARKET VALUE" means, as of
any date, the value of a share of the Company's Common Stock determined as
follows:

               (a)  if such Common Stock is then quoted on the Nasdaq National
                    Market, its closing price on the Nasdaq National Market on
                    the date of determination as reported in The Wall Street

                    Journal;
                    -------

               (b)  if such Common Stock is publicly traded and is then listed
                    on a national securities exchange, its closing price on the
                    date of determination on the principal national securities

               (c)  if such Common Stock is publicly traded but is not quoted on
                    the Nasdaq National Market nor listed or admitted to trading
                    on a national securities exchange, the average of the

                    faith, which in the case of the First Offering Date will be
                    the price per share at which shares of the Company's Common
                    Stock are initially offered for sale to the public by the
                    Company's underwriters in the initial public offering of the
                    Company's Common Stock pursuant to a registration statement
                    filed with the Securities and Exchange Commission (the
                    "SEC") under the Securities Act of 1933, as amended (the
                    "SECURITIES ACT").

     9.   PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
SHARES.

          (a)  The purchase price of the shares is accumulated by regular
payroll deductions made during each Offering Period. The deductions are made as
a percentage of the participant's compensation in one percent (1%) increments
not less than two percent (2%), nor greater than ten percent (10%) or such lower
limit set by the Committee. Compensation shall mean base salary not to exceed
$250,000 per calendar year, provided however, that for purposes of determining a
participant's compensation, any election by such participant to reduce his or
her regular cash remuneration under Sections 125 or 401(k) of the Code shall be
treated as if the participant did not make such election. Payroll deductions
shall commence on the first payday of the Offering Period and shall continue to
the end of the Offering Period unless sooner altered or terminated as provided
in this Plan.

          (b)  A participant may decrease or increase the rate of payroll
deductions during an Offering Period by filing with the Treasury Department a
new authorization for payroll deductions, in which case the new rate shall
become effective for the next payroll period commencing more than fifteen (15)
days after the Treasury Department's receipt of the authorization and shall
continue for the remainder of the Offering Period unless changed as described
below. Such change in the rate of payroll deductions may be made at any time
during an Offering Period, but not more than one (1) change may be made
effective during any Offering Period. A participant may increase or decrease the
rate of payroll deductions for any subsequent Offering Period by filing with the
Treasury Department a new authorization for payroll deductions not later than
fifteen (15) days before the beginning of such Offering Period.

          (c)  All payroll deductions made for a participant are credited to his
or her account under this Plan and are deposited with the general funds of the
Company. No interest accrues on the payroll deductions. All payroll deductions
received or held by the Company may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll
deductions.

          (d)  On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of
Common Stock reserved under the option granted to such participant with respect
to the Offering Period to the extent that such option is exercisable on the
Purchase Date. The purchase price per share shall be as specified in Section 8
of this Plan. Any cash remaining in a participant's account after such purchase
of shares shall be refunded to such participant in cash, without interest;
provided, however that any amount remaining in such participant's account on a
Purchase Date which is less than the amount necessary to purchase a full share
of Common Stock of the Company shall be carried forward, without interest, into
the next Purchase Period or Offering Period, as the case may be. In the event
that this Plan has been oversubscribed, all funds not used to purchase shares on
the Purchase Date shall be returned to the participant, without interest. No
Common Stock shall be purchased on a Purchase Date on behalf of any employee
whose participation in this Plan has terminated prior to such Purchase Date.

                                               1998 Employee Stock Purchase Plan

          (e)  As promptly as practicable after the Purchase Date, the Company
shall issue shares for the participant's benefit representing the shares
purchased upon exercise of his or her option.

          (f)  During a participant's lifetime, his or her option to purchase
shares hereunder is exercisable only by him or her. The participant will have no
interest or voting right in shares covered by his or her option until such
option has been exercised.

     10.  LIMITATIONS ON SHARES TO BE PURCHASED.

          (a)  No participant shall be entitled to purchase stock under this
Plan at a rate which, when aggregated with his or her rights to purchase stock
under all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan. The Company shall automatically suspend
the payroll deductions of any participant as necessary to enforce such limit
provided that when the Company automatically resumes such payroll deductions,
the Company must apply the rate in effect immediately prior to such suspension.

          (b)  No more than two hundred percent (200%) of the number of shares
determined by using eighty-five percent (85%) of the fair market value of a
share of the Company's Common Stock on the Offering Date as the denominator may
be purchased by a participant on any single Purchase Date.

          (c)  No participant shall be entitled to purchase more than the
Maximum Share Amount (as defined below) on any single Purchase Date. The maximum
number of shares which may be purchased by any employee at any single Purchase
Date (hereinafter the "MAXIMUM SHARE AMOUNT") shall be 1,000, until otherwise
determined by the Committee not less than thirty (30) days prior to the
commencement of any Offering Period. In no event shall the Maximum Share Amount
exceed the amounts permitted under Section 10(b) above. If a new Maximum Share
Amount is set, then all participants must be notified of such Maximum Share
Amount prior to the commencement of the next Offering Period. The Maximum Share
Amount shall continue to apply with respect to all succeeding Purchase Dates and
Offering Periods unless revised by the Committee as set forth above.

          (d)  If the number of shares to be purchased on a Purchase Date by all
employees participating in this Plan exceeds the number of shares then available
for issuance under this Plan, then the Company will make a pro rata allocation
of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Committee shall determine to be equitable. In such event,
the Company shall give written notice of such reduction of the number of shares
to be purchased under a participant's option to each participant affected.

          (e)  Any payroll deductions accumulated in a participant's account
which are not used to purchase stock due to the limitations in this Section 10
shall be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.

     11.  WITHDRAWAL.

          (a)  Each participant may withdraw from an Offering Period under this
Plan by signing and delivering to the Treasury Department a written notice to
that effect on a form provided for such purpose. Such withdrawal may be elected
at any time at least fifteen (15) days prior to the end of an Offering Period.

          (b)  Upon withdrawal from this Plan, the accumulated payroll
deductions shall be returned to the withdrawn participant, without interest, and
his or her interest in this Plan shall terminate. In the event a participant
voluntarily elects to withdraw from this Plan, he or she may not resume his or
her participation in this Plan during the same Offering Period, but he or she
may participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth in Section 6 above for initial
participation in this Plan.

                                               1998 Employee Stock Purchase Plan

          (c)  If the Fair Market Value on the first day of the current Offering
Period in which a participant is enrolled is higher than the Fair Market Value
on the first day of any subsequent Offering Period, the Company will
automatically enroll such participant in the subsequent Offering Period. Except
with respect to the first Offering Period, any funds accumulated in a
participant's account prior to the first day of such subsequent Offering Period
will be applied to the purchase of shares on the Purchase Date immediately prior
to the first day of such subsequent Offering Period. In the event that the Fair
Market Value on the First Offering Date is higher than the Fair Market Value on
the first day of the second Offering Period, any funds accumulated in a
participant's account prior to the first day of the second Offering Period will
be applied to the purchase of shares on the Purchase Date next following the
first day of such second Offering Period. A participant does not need to file
any forms with the Company to automatically be enrolled in the subsequent
Offering Period.

     12.  TERMINATION OF EMPLOYMENT.  Termination of a participant's employment
for any reason, including retirement, death or the failure of a participant to
remain an eligible employee of the Company or of a Participating Subsidiary,
immediately terminates his or her participation in this Plan. In such event, the
payroll deductions credited to the participant's account will be returned to him
or her or, in the case of his or her death, to his or her legal representative,
without interest. For purposes of this Section 12, an employee will not be
deemed to have terminated employment or failed to remain in the continuous
employ of the Company or of a Participating Subsidiary in the case of sick
leave, military leave, or any other leave of absence approved by the Board;
provided that such leave is for a period of not more than ninety (90) days or
- --------                                                                     
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

     13.  RETURN OF PAYROLL DEDUCTIONS.  In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall deliver to the participant all payroll deductions credited to such
participant's account. No interest shall accrue on the payroll deductions of a
participant in this Plan.

     14.  CAPITAL CHANGES.  Subject to any required action by the stockholders
of the Company, the number of shares of Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of
Common Stock which have been authorized for issuance under this Plan but have
not yet been placed under option (collectively, the "RESERVES"), as well as the
price per share of Common Stock covered by each option under this Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the Common Stock) or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of any
consideration by the Company; provided, however, that conversion of any
                              --------  -------                        
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the
Committee, whose determination shall be final, binding and conclusive. Except as
expressly provided herein, no issue by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option.

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee. The Committee may,
in the exercise of its sole discretion in such instances, declare that this Plan
shall terminate as of a date fixed by the Committee and give each participant
the right to purchase shares under this Plan prior to such termination. In the
event of (i) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the successor corporation, which assumption
will be binding on all participants), (ii) a merger in which the Company is the
surviving corporation but after which the stockholders of the Company
immediately prior to such merger (other than any stockholder that merges, or
which owns or controls another corporation that merges, with the Company in such
merger) cease to own their shares or other equity interest in the Company, (iii)
the sale of all or substantially all of the assets of the Company or (iv) the
acquisition, sale, or transfer of more than 50% of the outstanding shares of the

                                               1998 Employee Stock Purchase Plan

Company by tender offer or similar transaction, the Plan will terminate
immediately prior to the consummation of such transaction, unless otherwise
provided by the Committee.

     The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, or in the event of the Company being consolidated with or merged into any
other corporation.

     15.  NONASSIGNABILITY.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 22 below) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

     16.  REPORTS.  Individual accounts will be maintained for each participant
in this Plan. Each participant shall receive promptly after the end of each
Purchase Period a report of his or her account setting forth the total payroll
deductions accumulated, the number of shares purchased, the per share price
thereof and the remaining cash balance, if any, carried forward to the next
Purchase Period or Offering Period, as the case may be.

     17.  NOTICE OF DISPOSITION.  Each participant shall notify the Company in
writing if the participant disposes of any of the shares purchased in any
Offering Period pursuant to this Plan if such disposition occurs within two (2)
years from the Offering Date or within one (1) year from the Purchase Date on
which such shares were purchased (the "NOTICE PERIOD"). The Company may, at any
time during the Notice Period, place a legend or legends on any certificate
representing shares acquired pursuant to this Plan requesting the Company's
transfer agent to notify the Company of any transfer of the shares. The
obligation of the participant to provide such notice shall continue
notwithstanding the placement of any such legend on the certificates.

     18.  NO RIGHTS TO CONTINUED EMPLOYMENT.  Neither this Plan nor the grant of
any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.

     19.  EQUAL RIGHTS AND PRIVILEGES.  All eligible employees shall have equal
rights and privileges with respect to this Plan so that this Plan qualifies as 
an "employee stock purchase plan" within the meaning of Section 423 or any
successor provision of the Code and the related regulations. Any provision of
this Plan which is inconsistent with Section 423 or any successor provision of
the Code shall, without further act or amendment by the Company, the Committee
or the Board, be reformed to comply with the requirements of Section 423. This
Section 19 shall take precedence over all other provisions in this Plan.

     20.  NOTICES.  All notices or other communications by a participant to the
Company under or in connection with this Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     21.  TERM; STOCKHOLDER APPROVAL.  After this Plan is adopted by the Board,
this Plan will become effective on the First Offering Date (as defined above).
This Plan shall be approved by the stockholders of the Company, in any manner
permitted by applicable corporate law, within twelve (12) months before or after
the date this Plan is adopted by the Board. No purchase of shares pursuant to
this Plan shall occur prior to such stockholder approval. This Plan shall
continue until the earlier to occur of (a) termination of this Plan by the Board
(which termination may be effected by the Board at any time), (b) issuance of
all of the shares of Common Stock reserved for issuance under this Plan, or (c)
ten (10) years from the adoption of this Plan by the Board.

     22.  DESIGNATION OF BENEFICIARY.

                                               1998 Employee Stock Purchase Plan

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
this Plan in the event of such participant's death subsequent to the end of an
Purchase Period but prior to delivery to him of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under this Plan in the event
of such participant's death prior to a Purchase Date.

          (b)  Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under this Plan who is living at
the time of such participant's death, the Company shall deliver such shares or
cash to the executor or administrator of the estate of the participant, or if no
such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such shares or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

     23.  CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF SHARES.
Shares shall not be issued with respect to an option unless the exercise of such
option and the issuance and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange or automated quotation system upon which the shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

     24.  APPLICABLE LAW.  The Plan shall be governed by the substantive laws
(excluding the conflict of laws rules) of the State of California.

     25.  AMENDMENT OR TERMINATION OF THIS PLAN.  The Board may at any time
amend, terminate or extend the term of this Plan, except that any such
termination cannot affect options previously granted under this Plan, nor may
any amendment make any change in an option previously granted which would
adversely affect the right of any participant, nor may any amendment be made
without approval of the stockholders of the Company obtained in accordance with
Section 21 above within twelve (12) months of the adoption of such amendment (or
earlier if required by Section 21) if such amendment would:

          (a)  increase the number of shares that may be issued under this Plan;
or

          (b)  change the designation of the employees (or class of employees)
eligible for participation in this Plan.

                           INDEMNIFICATION AGREEMENT



          THIS INDEMNIFICATION AGREEMENT (this "Agreement") is entered into as
of September ___, 1997, by and among Exodus Communications, Inc., a California
corporation (the "Company") and each indemnitee ("Indemnitee") executing this
Agreement.

                                   RECITALS

     A.   The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees,
shareholders, controlling persons, agents and fiduciaries, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance.

     B.   The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
controlling persons, shareholders, agents and fiduciaries to expensive
litigation risks at the same time as the availability and coverage of liability
insurance has been severely limited.

     C.   Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, shareholders, controlling persons, agents and fiduciaries
of the Company may not be willing to serve in such capacities without additional
protection.

     D.   The Company (i) desires to attract and retain the involvement of
highly qualified individuals and entities, such as Indemnitee, to serve the
Company and, in part, in order to induce each Indemnitee to be involved with the
Company and (ii) wishes to provide for the indemnification and advancing of
expenses to each Indemnitee to the maximum extent permitted by law.

     E.   In view of the considerations set forth above, the Company desires
that each Indemnitee be indemnified by the Company as set forth herein.

          NOW, THEREFORE, the Company and each Indemnitee hereby agrees as
follows:

          1.   Indemnification.
               --------------- 

               a.   Indemnification of Expenses.  The Company shall indemnify 
                    ---------------------------                               
and hold harmless each Indemnitee (including its respective directors, officers,
partners, employees, agents and spouses) and each person who controls any of
them or who may be liable within the meaning of Section 15 of the Securities Act
of 1933, as amended (the "Securities Act"), or Section 20 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), to the
<PAGE>
 
fullest extent permitted by law if such Indemnitee was or is or becomes a party
to or witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any threatened, pending or completed action,
suit, proceeding or alternative dispute resolution mechanism, or any hearing,
inquiry or investigation that such Indemnitee believes might lead to the
institution of any such action, suit, proceeding or alternative dispute
resolution mechanism, whether civil, criminal, administrative, investigative or
other (hereinafter a "Claim") by reason of (or arising in part or in whole out
of) any event or occurrence related to the fact that Indemnitee is or was or may
be deemed a director, officer, shareholder, employee, controlling person, agent
or fiduciary of the Company, or any subsidiary of the Company, or is or was or
may be deemed to be serving at the request of the Company as a director,
officer, shareholder, employee, controlling person, agent or fiduciary of
another corporation, partnership, limited liability company, joint venture,
trust or other enterprise, or by reason of any action or inaction on the part of
such Indemnitee while serving in such capacity, including, without limitation,
any and all losses, claims, damages, expenses and liabilities, joint or several
(including any investigation, legal and other expenses incurred in connection
with, and any amount paid in settlement of, any action, suit, proceeding or any
claim asserted) under the Securities Act, the Exchange Act or other federal or
state statutory law or regulation, at common law or otherwise or which relate
directly or indirectly to the registration, purchase, sale or ownership of any
securities of the Company or to any fiduciary obligation owed with respect
thereto or as a direct or indirect result of any Claim made by any shareholder
of the Company against an Indemnitee and arising out of or related to any round
of financing of the Company (including but not limited to Claims regarding non-
participation, or non-pro rata participation, in such round by such
shareholder), or made by a third party against an Indemnitee based on any
misstatement or omission of a material fact by the Company in violation of any
duty of disclosure imposed on the Company by Federal or state securities or
common laws (hereinafter an "Indemnification Event") against any and all
expenses (including attorneys' fees and all other costs, expenses and
obligations incurred in connection with investigating, defending a witness in or
participating in (including on appeal), or preparing to defend, be a witness in
or participate in, any such action, suit, proceeding, alternative dispute
resolution mechanism, hearing, inquiry or investigation), judgments, fines,
penalties and amounts paid in settlement (if, and only if, such settlement is
approved in advance by the Company, which approval shall not be unreasonably
withheld) of such Claim and any federal, state, local or foreign taxes imposed
on Indemnitee as a result of the actual or deemed receipt of any payments under
this Agreement (collectively, hereinafter "Expenses"), including all interest,
assessments and other charges paid or payable in connection with or in respect
of such Expenses.  Such payment of Expenses shall be made by the Company as soon
as practicable but in any event no later than ten (10) days after written demand
by the Indemnitee therefor is presented to the Company.

               b.   Reviewing Party.  Notwithstanding the foregoing, (i) the 
                    ---------------                                          
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(e) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and  

                                       2
<PAGE>
 
(ii) and each Indemnitee acknowledges and agrees that the obligation of the
Company to make an advance payment of Expenses to Indemnitee pursuant to Section
2(a) (an "Expense Advance") shall be subject to the condition that, if, when and
to the extent that the Reviewing Party determines that Indemnitee would not be
permitted to be so indemnified under applicable law, the Company shall be
entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the
Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed). Indemnitee's obligation to reimburse the Company for any
Expense Advance shall be unsecured and no interest shall be charged thereon. If
there has not been a Change in Control (as defined in Section 10(c) hereof), the
Reviewing Party shall be selected by the Board of Directors, and if there has
been such a Change in Control (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), the Reviewing Party shall be the
Independent Legal Counsel referred to in Section 1(e) hereof. If there has been
no determination by the Reviewing Party or if the Reviewing Party determines
that Indemnitee substantively would not be permitted to be indemnified in whole
or in part under applicable law, Indemnitee shall have the right to commence
litigation seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases therefor, and the Company hereby consents to service of process
and to appear in any such proceeding. Any determination by the Reviewing Party
otherwise shall be conclusive and binding on the Company and Indemnitee.

               c.   Contribution.  If the indemnification provided for in 
                    ------------                                          
Section 1(a) above for any reason is held by a court of competent jurisdiction
to be unavailable to an Indemnitee in respect of any losses, claims, damages,
expenses or liabilities referred to therein, then the Company, in lieu of
indemnifying such Indemnitee thereunder, shall contribute to the amount paid or
payable by such Indemnitee as a result of such losses, claims, damages, expenses
or liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Indemnitee, or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company and the
Indemnitee in connection with the action or inaction which resulted in such
losses, claims, damages, expenses or liabilities, as well as any other relevant
equitable considerations. In connection with the registration of the Company's
securities, the relative benefits received by the Company and the Indemnitee
shall be deemed to be in the same respective proportions that the net proceeds
from the offering (before deducting expenses) received by the Company and the
Indemnitee, in each case as set forth in the table on the cover page of the
applicable prospectus, bear to the aggregate public offering price of the
securities so offered.  The relative fault of the 

                                       3
<PAGE>
 
Company and the Indemnitee shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Indemnitee and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the Indemnitee agree that it would not be just and
equitable if contribution pursuant to this Section 1(c) were determined by pro
rata or per capita allocation or by any other method of allocation which does
not take account of the equitable considerations referred to in the immediately
preceding paragraph. In connection with the registration of the Company's
securities, in no event shall Indemnitee be required to contribute any amount
under this Section 1(c) in excess of the lesser of (i) that proportion of the
total of such losses, claims, damages or liabilities indemnified against equal
to the proportion of the total securities sold under such registration statement
which is being sold by such Indemnitee or (ii) the proceeds received by such
Indemnitee from its sale of securities under such registration statement. No
person found guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not found guilty of such fraudulent misrepresentation.

               d.   Survival Regardless of Investigation.  The indemnification 
                    ------------------------------------                      
and contribution provided for in this Section 1 will remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnitee or
any officer, director, employee, agent or controlling person of the Indemnitee.

               e.   Change in Control.  The Company agrees that if there is a 
                    -----------------                                         
Change in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
under this Agreement or any other agreement or under the Company's Amended and
Restated Articles of Incorporation (the "Restated Articles") or Restated Bylaws
as now or hereafter in effect, Independent Legal Counsel (as defined in Section
10(d) hereof) shall be selected by the Indemnitee and approved by the Company
(which approval shall not be unreasonably withheld). Such counsel, among other
things, shall render its written opinion to the Company and Indemnitee as to
whether and to what extent Indemnitee would be permitted to be indemnified under
applicable law. The Company agrees to abide by such opinion and to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

               f.   Mandatory Payment of Expenses.  Notwithstanding any other
                    -----------------------------                             
provision of this Agreement, to the extent that Indemnitee has been successful
on the merits or otherwise, including, without limitation, the dismissal of an
action without prejudice, in the defense of any action, suit, proceeding,
inquiry or investigation referred to in Section 1(a) hereof 

                                       4
<PAGE>
 
or in the defense of any claim, issue or matter therein, each Indemnitee shall
be indemnified against all Expenses incurred by such Indemnitee in connection
herewith.

          2.   Expenses; Indemnification Procedure.
               ----------------------------------- 

               a.   Advancement of Expenses.  The Company shall advance all
                    -----------------------                            
Expenses incurred by Indemnitee. The advances to be made hereunder shall be paid
by the Company to Indemnitee as soon as practicable but in any event no later
than fifteen (15) days after written demand by such Indemnitee therefor to the 
Company.

               b.   Notice/Cooperation by Indemnitee.  Indemnitee shall give the
                    --------------------------------                    
Company notice as soon as practicable of any Claim made against Indemnitee for
which indemnification will or could be sought under this Agreement. Notice to
the Company shall be directed to the Chief Executive Officer of the Company at
the address shown on the signature page of this Agreement (or such other address
as the Company shall designate in writing to Indemnitee).

               c.   No Presumptions; Burden of Proof.  For purposes of this
                    --------------------------------                   
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
                                                                 ----
contendere, or its equivalent, shall not create a presumption that Indemnitee
- ----------
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief. In connection with any determination by the Reviewing
Party or otherwise as to whether Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

               d.   Notice to Insurers.  If, at the time of the receipt by the
                    ------------------                                    
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt written notice of the commencement of such Claim to the insurers in
accordance with the procedures set forth in each of the policies. The Company
shall thereafter take all necessary or desirable action to cause such insurers
to pay, on behalf of Indemnitee, all amounts payable as a result of such action,
suit, proceeding, inquiry or investigation in accordance with the terms of such
policies.

               e.   Selection of Counsel.  In the event the Company shall be
                    --------------------                                 
obligated hereunder to pay the Expenses of any Claim, the Company shall be
entitled to assume the defense

                                       5
<PAGE>
 
of such Claim, with counsel reasonably approved by the applicable Indemnitee,
upon the delivery to such Indemnitee of written notice of its election to do so.
After delivery of such notice, approval of such counsel by the Indemnitee and
the retention of such counsel by the Company, the Company will not be liable to
such Indemnitee under this Agreement for any fees of counsel subsequently
incurred by such Indemnitee with respect to the same Claim; provided that, (i)
                                                            -------------
the Indemnitee shall have the right to employ such Indemnitee's counsel in any
such Claim at the Indemnitee's expense; (ii) the Indemnitee shall have the right
to employ his own counsel in connection with any such proceeding, at the expense
of the Company, if such counsel serves in a review, observer, advice and
counseling capacity and does not otherwise materially control or participate in
the defense of such proceeding; and (iii) if (A) the employment of counsel by
the Indemnitee has been previously authorized by the Company, (B) such
Indemnitee shall have reasonably concluded that there is a conflict of interest
between the Company and such Indemnitee in the conduct of any such defense, or
(C) the Company shall not continue to retain such counsel to defend such Claim,
then the fees and expenses of the Indemnitee's counsel shall be at the expense
of the Company.

          3.   Additional Indemnification Rights; Nonexclusivity.
               ------------------------------------------------- 

               a.   Scope.  The Company hereby agrees to indemnify Indemnitee 
                    -----                                                    
to the fullest extent permitted by law, even if such indemnification is not
specifically authorized by the other provisions of this Agreement or any other
agreement, the Company's Articles of Incorporation, the Company's Bylaws or by
statute. In the event of any change after the date of this Agreement in any
applicable law, statute or rule which expands the right of a California
corporation to indemnify a member of its Board of Directors or an officer,
shareholder, employee, controlling person, agent or fiduciary, it is the intent
of the parties hereto that Indemnitee shall enjoy by this Agreement the greater
benefits afforded by such change. In the event of any change in any applicable
law, statute or rule which narrows the right of a California corporation to
indemnify a member of its Board of Directors or an officer, employee, agent or
fiduciary, such change, to the extent not otherwise required by such law,
statute or rule to be applied to this Agreement, shall have no effect on this
Agreement or the parties' rights and obligations hereunder except as set forth
in Section 8(a) hereof.

               b.   Nonexclusivity.  The indemnification provided by this 
                    --------------                                        
Agreement shall be in addition to any rights to which Indemnitee may be entitled
under the Company's Articles of Incorporation, its Bylaws, any agreement, any
vote of shareholders or disinterested directors, the laws of the State of
California, or otherwise. The indemnification provided under this Agreement
shall continue as to each Indemnitee for any action such Indemnitee took or did
not take while serving in an indemnified capacity even though the Indemnitee may
have ceased to serve in such capacity and such indemnification shall inure to
the benefit of each Indemnitee from and after Indemnitee's first day of service
as a director with the Company or affiliation with a Director from and after the
date such Director commences services as a director with the Company.

          4.   No Duplication of Payments.  The Company shall not be liable 
               --------------------------                                  
under this 

                                       6
<PAGE>
 
Agreement to make any payment in connection with any Claim made against any
Indemnitee to the extent such Indemnitee has otherwise actually received payment
(under any insurance policy, Articles, Bylaws or otherwise) of the amounts
otherwise indemnifiable hereunder.

          5.   Partial Indemnification.  If any Indemnitee is entitled under any
               -----------------------                                          
provision of this Agreement to indemnification by the Company for any portion of
Expenses incurred in connection with any Claim, but not, however, for all of the
total amount thereof, the Company shall nevertheless indemnify Indemnitee for
the portion of such Expenses to which such Indemnitee is entitled.

          6.   Mutual Acknowledgement.  The Company and each Indemnitee 
               ----------------------                                   
acknowledge that in certain instances, Federal law or applicable public policy
may prohibit the Company from indemnifying its directors, officers, employees,
controlling persons, agents or fiduciaries under this Agreement or otherwise.

          7.   Liability Insurance.  Upon the approval of the Board of Directors
               -------------------                                           
of the Company, to the extent the Company maintains liability insurance
applicable to directors, officers, employees, control persons, agents or
fiduciaries, each Indemnitee shall be covered by such policies in such a manner
as to provide Indemnitee the same rights and benefits as are accorded to the
most favorably insured of the Company's directors, if such Indemnitee is a
director, or of the Company's officers, if such Indemnitee is not a director of
the Company but is an officer; or of the Company's key employees, controlling
persons, agents or fiduciaries, if such Indemnitee is not an officer or director
but is a key employee, agent, control person, or fiduciary.

          8.   Exceptions.  Any other provision herein to the contrary 
               ----------                                              
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

               a.   Claims Initiated by Indemnitee.  To indemnify or advance 
                    ------------------------------                           
expenses to any Indemnitee with respect to Claims initiated or brought
voluntarily by such Indemnitee and not by way of defense, except (i) with
respect to actions or proceedings to establish or enforce a right to indemnify
under this Agreement or any other agreement or insurance policy or under the
Company's Articles or Bylaws now or hereafter in effect relating to Claims for
Indemnifiable Events, (ii) in specific cases if the Board of Directors has
approved the initiation or bringing of such Claim, or (iii) as otherwise
required under California statute or law, regardless of whether such Indemnitee
ultimately is determined to be entitled to such indemnification, advance expense
payment or insurance recovery, as the case may be; or

               b.   Claims Under Section 16(b).  To indemnify any Indemnitee 
                    --------------------------                               
for expenses and the payment of profits arising from the purchase and sale by
such Indemnitee of securities in violation of Section 16(b) of the Exchange Act
or any similar successor statute; or

                                       7
<PAGE>
 
               c.   Unlawful Indemnification.  To indemnify an Indemnitee if a
                    ------------------------                                 
final decision by a court having jurisdiction in the matter shall determine that
such indemnification is not lawful.

          9.   Period of Limitations.  No legal action shall be brought and no
               ---------------------                                          
cause of action shall be asserted by or in the right of the Company against any
Indemnitee, any Indemnitee's estate, spouse, heirs, executors or personal or
legal representatives after the expiration of five (5) years from the date of
accrual of such cause of action, and any claim or cause of action of the Company
shall be extinguished and deemed released unless asserted by the timely filing
of a legal action within such five (5) year period; provided, however, that if
                                                    --------  -------         
any shorter period of limitations is otherwise applicable to any such cause of
action, such shorter period shall govern.

          10.  Construction of Certain Phrases.
               ------------------------------- 

               a.   For purposes of this Agreement, references to the "Company"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees,
agents or fiduciaries, so that if Indemnitee is or was or may be deemed a
director, officer, employee, agent, control person, or fiduciary of such
constituent corporation, or is or was or may be deemed to be serving at the
request of such constituent corporation as a director, officer, employee,
control person, agent or fiduciary of another corporation, partnership, joint
venture, employee benefit plan, trust or other enterprise, each Indemnitee shall
stand in the same position under the provisions of this Agreement with respect
to the resulting or surviving corporation as each Indemnitee would have with
respect to such constituent corporation if its separate existence had continued.

               b.   For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on any Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee, agent or fiduciary of the
Company which imposes duties on, or involves services by, such director,
officer, employee, agent or fiduciary with respect to an employee benefit plan,
its participants or its beneficiaries; and if any Indemnitee acted in good faith
and in a manner such Indemnitee reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan, such Indemnitee
shall be deemed to have acted in a manner "not opposed to the best interests of
the Company" as referred to in this Agreement.

               c.   For purposes of this Agreement a "Change in Control" shall
be deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d)(3) and 14(d)(2) of the Exchange Act), other than a trustee or other
fiduciary holding securities under an employee benefit plan of the Company or a
corporation owned directly or indirectly by the 

                                       8
<PAGE>
 
shareholders of the Company in substantially the same proportions as their
ownership of stock of the Company, (A) who is or becomes the beneficial owner,
directly or indirectly, of securities of the Company representing 20% or more of
the combined voting power of the Company's then outstanding Voting Securities,
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Exchange Act), directly or indirectly, of
securities of the Company representing more than 30% of the total voting power
represented by the Company's then outstanding Voting Securities, (ii) during any
period of two consecutive years, individuals who at the beginning of such period
constitute the Board of Directors of the Company and any new director whose
election by the Board of Directors or nomination for election by the Company's
shareholders was approved by a vote of at least two-thirds (2/3) of the
directors then still in office who either were directors at the beginning of the
period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority thereof, or (iii) the shareholders
of the Company approve a merger or consolidation of the Company with any other
corporation other than a merger or consolidation which would result in the
Voting Securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into Voting Securities of the surviving entity) at least two-thirds (2/3) of the
total voting power represented by the Voting Securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation, or
the shareholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of (in one
transaction or a series of transactions) all or substantially all of the
Company's assets.

               d.   For purposes of this Agreement, "Independent Legal Counsel"
shall mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1(e) hereof, who shall not have otherwise performed
services for the Company or any Indemnitee within the last three (3) years
(other than with respect to matters concerning the right of any Indemnitee under
this Agreement, or of other indemnitees under similar indemnity agreements).

               e.   For purposes of this Agreement, a "Reviewing Party" shall
mean any appropriate person or body consisting of a member or members of the
Company's Board of Directors or any other person or body appointed by the Board
of Directors who is not a party to the particular Claim for which Indemnitee is
seeking indemnification, or Independent Legal Counsel.

               f.   For purposes of this Agreement, "Voting Securities" shall
mean any securities of the Company that vote generally in the election of
directors.

          11.  Counterparts. This Agreement may be executed in one or more 
               ------------ 
counterparts, each of which shall constitute an original.

          12.  Binding Effect; Successors and Assigns. This Agreement shall be
               --------------------------------------                         
binding 

                                       9
<PAGE>
 
upon and inure to the benefit of and be enforceable by the parties hereto and
their respective successors, assigns, including any direct or indirect successor
by purchase, merger, consolidation or otherwise to all or substantially all of
the business and/or assets of the Company, spouses, heirs, and personal and
legal representatives. The Company shall require and cause any successor
(whether direct or indirect by purchase, merger, consolidation or otherwise) to
all, substantially all, or a substantial part, of the business and/or assets of
the Company, by written agreement in form and substance satisfactory to each
Indemnitee, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform if
no such succession had taken place. This Agreement shall continue in effect with
respect to Claims relating to Indemnifiable Events regardless of whether any
Indemnitee continues to serve as a director, officer, employee, agent,
controlling person, or fiduciary of the Company or of any other enterprise,
including subsidiaries of the Company, at the Company's request.

          13.  Attorneys' Fees. In the event that any action is instituted by an
               ---------------                                                  
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, any Indemnitee shall be entitled to be paid all Expenses incurred by
such Indemnitee with respect to such action, regardless of whether such
Indemnitee is ultimately successful in such action, and shall be entitled to the
advancement of Expenses with respect to such action, unless, as a part of such
action, a court of competent jurisdiction over such action determines that each
of the material assertions made by such Indemnitee as a basis for such action
was not made in good faith or was frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement to enforce or
interpret any of the terms of this Agreement, the Indemnitee shall be entitled
to be paid all Expenses incurred by such Indemnitee in defense of such action
(including costs and expenses incurred with respect to Indemnitee counterclaims
and cross-claims made in such action), and shall be entitled to the advancement
of Expenses with respect to such action.

          14.  Notice. All notices and other communications required or 
               ------                                                   
permitted hereunder shall be in writing, shall be effective when given, and
shall in any event be deemed to be given (a) five (5) days after deposit with
the U.S. Postal Service or other applicable postal service, if delivered by
first class mail, postage prepaid, (b) upon delivery, if delivered by hand, (c)
one business day after the business day of deposit with Federal Express or
similar overnight courier, freight prepaid, or (d) one day after the business
day of delivery by facsimile transmission, if deliverable by facsimile
transmission, with copy by first class mail, postage prepaid, and shall be
addressed if to Indemnitee, at each Indemnitee's address as set forth beneath
the Indemnitee' signatures to this Agreement and if to the Company at the
address of its principal corporate offices (attention: Secretary) or at such
other address as such party may designate by ten (10) days' advance written
notice to the other party hereto.

          15.  Consent to Jurisdiction.  The Company and each Indemnitee each 
               -----------------------                                        
hereby irrevocably consent to the jurisdiction and venue of the courts of the

time as additional buildings are made a part of the Project and such percentage
is adjusted.

          R.   TENANT'S PERSONAL PROPERTY. Tenant's trade fixtures, furniture,
               --------------------------

          S.   TERM. The term of this Lease, set forth in Paragraph 4.A, as it
               ----
may be extended by written agreement between Landlord and Tenant.

     4.   LEASE TERM.

          A.   TERM.  The term of this Lease shall be fore five (5) years (or
               ----                                                          
sixty (60) months) commencing on May 1, 1996 ("Commencement Date") and expiring
on April 30, 2001.  Except as otherwise provided in Paragraph 4.C. below, if for
any reason whatsoever, Landlord cannot deliver possession of the Premises to
Tenant on the Commencement Date, this Lease shall not be void or voidable, nor
shall Landlord, or Landlord's agents, be liable to Tenant for any loss or damage
resulting therefrom.  Tenant shall not be liable for Rent until Landlord
delivers possession of the Premises to Tenant and, notwithstanding the foregoing
to the contrary, the date that Landlord delivers possession of the Premises to
Tenant shall be the Commencement Date.  The expiration date of the Term as set
forth in this Paragraph 4.A. shall be extended by the same number of days that
Landlord's delivery of the Premises to Tenant was delayed.

          B.   EARLY ENTRY.  If Tenant is permitted to occupy the Premises prior
               -----------                                                      
to the Commencement Date for the purpose of fixturing or any other purpose
permitted by Landlord, such early entry shall be at Tenant's sole risk and
subject to all the terms and provisions hereof, except for the payment of
Monthly Rent which shall commence on the Commencement Date.  Landlord shall have
the right to impose such additional conditions on Tenant's early entry as
Landlord shall deem appropriate, and shall further have the right to require
that Tenant execute an early entry agreement containing such conditions prior to
Tenant's early entry.

          C.   DELAY IN DELIVERING POSSESSION.  In the event that for reasons
               ------------------------------                                
other than a delay resulting from a force majeure (hereafter defined in
Paragraph 39.N. below) ("Force Majeure Delay") or a delay resulting from any act
or failure to act by Tenant, Tenant's employees, agents, architects, independent
contractors, and/or consultants ("Tenant Delay"), Landlord has not delivered the
Premises to Tenant by June 1, 1996, then Tenant may elect to terminate the
Lease.  The occurrence of a Force Majeure Delay or Tenant Delay shall extend the
June 1, 1996 date for a period equal to the duration of the Force Majeure Delay
or the Tenant Delay.  Termination of the Lease as provided for herein shall be
the sole and exclusive remedy of Tenant for Landlord's failure to deliver the
Premises.  Tenant shall exercise the right to terminate provided for herein by
giving Landlord written notice of its intent to so terminate ("Termination
Notice").  The Termination Notice shall be given, if at all, on or before the
tenth (10th) day after

                                       3
<PAGE>
 
June 1, 1996, or the date to which this date has been extended as provided for
herein.  If the Termination Notice is not given as and when required hereunder,
then Tenant shall not be entitled to terminate the Lease.  Termination of the
Lease shall be effective on the date of Landlord's receipt of the Termination
Notice.

     5.   RENT.

          A.   MONTHLY RENT.  Tenant shall pay to Landlord, in lawful money of
               ------------                                                   
the United States, for each calendar month of the Term, net Monthly Rent as
shown below, in advance, on the first day of each calendar month, without
abatement, deduction, claim, offset, prior notice or demand:

               Months of Term                Net Monthly Rent
               --------------                ----------------

                   01 - 60                      $15,708.00

          B.   ADDITIONAL RENT.  Additionally, Tenant shall pay, as and with the
               ---------------                                                  
net Monthly Rent, Tenant's Percentage of the estimated monthly Operating
Expenses, as adjusted from time to time, and as more specifically set forth in
Paragraph 17.C.  Tenant shall deposit with Landlord upon execution of this Lease
the following amounts to be applied toward Rent due for the first month of the
Term:

               Monthly Rent (net)            $15,708.00/month

               Tenant's Percentage of
               Operating Expenses            $ 2,999.00/month

                             TOTAL           $18,707.00/month

All monies (except Monthly Rent) required to be paid by Tenant under this Lease,
including, without limitation, Operating Expenses, shall be deemed Additional
Rent.

          C.   PRORATIONS.  If the Commencement Date is not the first (1st) day
               ----------                                                      
of a month, or if the expiration date of this Lease is not the last day of a
month, a prorated installment of Rent based on a thirty (30) day month shall be
paid for the fractional month during which the Lease commences or expires.

     6.   LATE PAYMENT CHARGES.  Tenant acknowledges that late payment by Tenant
to Landlord of Rent and other charges provided for under this Lease will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of such
costs being extremely difficult or impracticable to fix.  Therefore, if any
installment of Rent or any other charge due from Tenant is not received by
Landlord within five (5) days after the date due, Tenant shall pay to Landlord
an additional sum equal to five percent (5%) of the amount overdue as a late
charge for every month or portion thereof that the Rent or other charges remain
unpaid.  The parties

                                       4
<PAGE>
 
agree that this late charge represents a fair and reasonable estimate of the
costs that Landlord will incur by reason of the late payment by Tenant.

     7.   SECURITY DEPOSIT. Tenant shall deposit with Landlord upon execution of
this Lease Fifteen Thousand Seven Hundred Eight and no/100ths Dollars
($15,708.00( (the "Cash Security Deposit") and a Letter of Credit in the amount
of One Hundred Thirty-Eight Thousand and no/100ths Dollars ($138,000.00)
("Letter of Credit Security Deposit"), both as security for the full and
faithful performance of every provision of this Lease to be performed by Tenant.
The Letter of Credit Security Deposit shall be (i) issued by a commercial bank
satisfactory to Landlord ("Issuer"), (ii) be a stand-by, at-sight, irrevocable
letter of credit, (iii) be payable to Landlord, (iv) require that any draw on
the letter of credit shall be made only upon receipt by the Issuer of a written

year or longer after the date of its issuance, and (vi) provide that it is
governed by the Uniform Customs and Practice for Documentary Credits,
International Chamber of Commerce Publication No. 400. If Tenant defaults with
respect to any provision of this Lease, Landlord may apply all or any part of
the Cash Security Deposit for the payment of any Rent or other sum in default,
the repair of such damage to the Premises or the payment of any other amount
which Landlord may spend or become obligated to spend by reason of Tenant's
default or to compensate Landlord for any other loss or damage which Landlord
may suffer by reason of Tenant's default to the full extent permitted by law.
Without limiting the generality of the foregoing, Tenant hereby acknowledges
that the following shall constitute loss or damage incurred by Landlord by
reason of a default by Tenant hereunder and Landlord shall be entitled to draw
on the Letter of Credit Security Deposit to reimburse Landlord for the following
costs incurred by Landlord: leasing fees and/or commissions paid in connection
with entering into this Lease, reasonable attorneys' fees and costs incurred in
connection with entering into this Lease, and all other costs incurred in
connection with entering into this Lease and delivering the Premises to
Landlord. If any portion of the Cash Security Deposit is applied as permitted
hereunder, Tenant shall, within ten (10) days after written demand therefor,
deposit cash with Landlord in an amount sufficient to restore the Cash Security
Deposit to its original amount. In the event that Landlord draws on the Letter
of Credit Security Deposit as permitted hereunder, Tenant shall cause a
replacement letter of credit to be deposited in the original amount of the
Letter of Credit Security Deposit. Within thirty (30) days prior to expiration
of the existing Letter of Credit Security Deposit, Tenant shall cause the Issuer
to issue and deliver to Landlord a replacement letter of credit. In the event
that Landlord assigns its rights under the Lease then Tenant shall cause a
replacement Letter to Credit Security Deposit to be issued in the name of the
assignee. If Tenant is not otherwise in default, the Cash Security Deposit or
any balance thereof and the Letter of Credit Security Deposit shall be returned
to Tenant within thirty (30) days after the expiration of the Term.

     8.   HOLDING OVER.  If Tenant remains in possession of all or any part of
the Premises after the expiration of the Term, with the express or implied
consent of Landlord, such tenancy shall be month-to-month only and shall not
constitute a renewal or extension for any further term.  If Tenant remains in
possession either with or without Landlord's consent, Monthly Rent shall be
increased to an amount equal to one hundred fifty percent (150%) of the Monthly
Rent payable during the last month of the Term, and any other sums due under
this Lease shall be payable in the amount and at the times specified in this
Lease.  Such month-to-month tenancy shall be subject to every other term,
condition, and covenant contained herein.  If Tenant remains in possession

Tenant shall be deemed to have accepted the Premises in the condition required
hereunder, subject to all applicable laws, codes and ordinances.  And damage to

     11.  USE OF THE PREMISES.

          A.   TENANT'S USE.  Tenant shall use the Premises solely for (i)

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

               (i)    Tenant agrees to complete prior to Lease execution the
questionnaire attached to the Lease as EXHIBIT E (the "Hazardous Materials
                                       ---------

or use of Hazardous Materials by Tenant and Tenant's employees, contractors,
subcontractors, invitees and sublessees (collectively "Tenant's Agents") in or
about the Premises, shall strictly comply with all applicable Hazardous
Materials Laws. Tenant shall indemnify, defend upon demand with counsel

consequential damages, interest, penalties, fines, monetary sanctions,
attorneys' fees, experts' fees, court costs, remediation costs, investigation
costs, and other expenses which result from or arise in any manner whatsoever
out of the use, storage, treatment, transportation, release, or disposal of
Hazardous Materials on or about the Premises or the Project by Tenant or
Tenant's Agents.

               (iii)  If the presence of Hazardous Materials in, on, or about
the Premises or the Project caused or permitted by Tenant or Tenant's Agents
results in contamination or deterioration of water or soil resulting in a level
of contamination greater than the levels established as acceptable by any
governmental agency having jurisdiction over such contamination, then Tenant
shall promptly take any and all action necessary to investigate and remediate
such contamination if required by Law or as a condition to the issuance or
continuing effectiveness of any governmental approval which relates to the use
of the Premises or any part thereof. Tenant shall further be solely responsible
for, and shall defend, indemnify, and hold Landlord and Landlord's Agents
harmless from and against, all claims, costs and liabilities, including
attorney's fees and costs, arising out of or in connection with any
investigation and remediation required hereunder to return the Premises to its

               (iv)   Landlord and Tenant shall each give written notice to the
other as soon as reasonably practicable of (i) any Hazardous Materials which

types or quantities differing from those set forth in the Hazardous Materials
Questionnaire without first obtaining the written permission of the Landlord. At
any time during the Lease term, Tenant shall, within five (5) days after written

about the Outside Area of the Project, and may cause the ground water to be
tested to detect the presence of Hazardous Materials by the use of such tests as
are then customarily used for such purposes, provided that Landlord shall use
diligent efforts to minimize any inconvenience or disruption to Tenant's
business in connection with such installation. If Tenant so requests, Landlord
shall supply Tenant with copies of such test results. The cost of such tests and
of the installation, maintenance, repair and replacement of such wells shall be
paid by Tenant if such tests disclose the existence of facts which give rise to
liability of Tenant pursuant to its indemnity given in Paragraph 11.D(ii) or
(iii).

Paragraph 11.D shall survive the expiration or earlier termination of the Lease
term. The rights and obligations of Landlord and Tenant with respect to issues
relating to Hazardous Materials are exclusively established by this Paragraph
11.D. In the event of any inconsistency between any other part of the Lease and

or about the Premises, except for nonstructural Alterations not exceeding Five
Thousand Dollars ($5,000.00) in cost per calendar year, without the prior
written consent of Landlord, and according to plans and specifications approved
in writing by Landlord, which consent shall not be unreasonably withheld.  With
regard to Alterations not requiring Landlord's consent, Tenant shall provide

compliance with all applicable laws and the CC&Rs, by a licensed contractor,
shall be done in a good and workmanlike manner conforming in quality and design
with the Premises existing as of the Commencement Date, and shall not diminish
the value of either the Building or the Premises.  All Alterations made by
Tenant shall be and become the property of Landlord upon installation and shall
not be deemed Tenant's Personal Property; provided, however, that Landlord shall
at the time consent for the Alterations is requested, notify Tenant, whether
Tenant must at the expiration or earlier termination of the Term, remove, at
Tenant's expense, any or all Alterations installed by Tenant and return the
Premises to their condition prior to the installation of such Alterations,
normal wear and tear excepted.  Notwithstanding any other provision of this
Lease, Tenant shall be solely responsible for the maintenance and repair of any
and all Alterations made by it to the Premises.  Tenant shall give Landlord

such work.

     14.  SURRENDER OF THE PREMISES.  Upon the expiration or earlier termination
of the Term, Tenant shall surrender the Premises to Landlord in its condition

satisfaction of Landlord.  Tenant shall remove from the Premises all of Tenant's
Alterations required to be removed pursuant to Paragraph 13 and all Tenant's
Personal Property, and repair any damage and perform any restoration work caused
by such removal.  If Tenant fails to remove such Alterations and Tenant's
Personal Property, and such failure continues after the termination of this
Lease, Landlord may retain such property and all rights of Tenant with respect
to it shall cease, or Landlord may place all or any portion of such property in
public storage for Tenant's account.  Tenant shall be liable to Landlord for
costs of removal of any such Alterations and Tenant's Personal Property and
storage and transportation costs of same, and the cost of repairing and
restoring the Premises, together with interest at the Interest Rate from the
date of expenditure by Landlord.  If the Premises are not so surrendered at the
expiration or earlier termination of this Lease, Tenant shall indemnify, defend

liabilities, including attorneys' fees and costs, resulting from Tenant's delay
in so surrendering the Premises.

     15.  PERSONAL PROPERTY TAXES.  Tenant shall pay prior to delinquency all

Tenant's Percentage or other equitable basis as determined by Landlord.
Landlord shall not be liable in damages or otherwise for any failure or
interruption of any utility service or other service furnished to the Premises,

Landlord.

     17.  REPAIR AND MAINTENANCE.

          A.   LANDLORD'S OBLIGATIONS.  Landlord shall maintain in good order,
               ----------------------                                         
condition and repair the structural parts of the Building, including the
foundation and subflooring of the Building, the roof (including the roof
membrane), exterior walls and interior bearing or

                                      10
<PAGE>
 
structural walls (excluding, however, interior wall surfaces), except for any
damage thereto caused by the negligence or willful acts or omissions of Tenant
or of Tenant's agents, employees or invitees, or by reason of the failure of
Tenant to perform or comply with any terms of this Lease, or caused by
Alterations made by Tenant or by Tenant's agents, employees or contractors.
Landlord also shall maintain the Outside Area in good order, condition and
repair. Landlord shall at all times have exclusive control of the Outside Area,
including the right to grant easements or other rights of access to third
parties, and may at any time temporarily close any part thereof, exclude and
restrain anyone from any part thereof, except the bona fide customers, employees
and invitees of Tenant who use the Outside Area in accordance with the rules and
regulations as Landlord may from time to time promulgate, and may change the
configuration of the Outside Area. In exercising any such rights, Landlord shall
make a reasonable effort to minimize any disruption of Tenant's business. It is
an express condition precedent to all obligations of Landlord to repair that
Tenant shall have notified Landlord of the need for such repairs. Tenant waives
the provisions of Sections 1941 and 1942 of the California Civil Code and any
similar or successor law regarding Tenant's right to make repairs and deduct the
expenses of such repairs from the Rent due under this Lease.

          B.  TENANT'S OBLIGATIONS.  Tenant shall at all times and at its own

expense clean, keep and maintain in good order, condition and repair every part
of the Premises which is not within Landlord's obligation pursuant to Paragraph
17.A. Tenant's repair and maintenance obligations shall include all plumbing and
sewage facilities within the Premises, fixtures, interior walls and ceiling,
floors, windows, doors, entrances, plateglass, showcases, skylights, all
electrical facilities and equipment, including lighting fixtures, lamps, fans
and any exhaust equipment and systems, any automatic fire extinguisher equipment
within the Premises, electrical motors and all other appliances and equipment of
every kind and nature located in, upon or about the Premises. Tenant shall also
be responsible for all pest control within the Premises. Tenant shall obtain
HVAC systems preventive maintenance contracts with quarterly service (or such
other periodic service as Landlord shall designate) in accordance with
manufacturer recommendations, which shall be subject to the reasonable approval
of Landlord and paid for by Tenant, and which shall provide for and include
replacement of filters, oiling and lubricating of machinery, parts replacement,
adjustment of drive belts, oil changes and other preventive maintenance,
including annual maintenance of duct work, interior unit drains and caulking of
sheet metal, and recaulking of jacks and vents on an annual basis. Tenant shall
have the benefit of all warranties available to Landlord regarding the equipment
in such HVAC systems. Tenant shall provide Landlord with copies of all HVAC
maintenance reports on a quarterly basis, including copies of contractor
recommendations for repairs and/or replacements. If any repairs and/or
replacements are recommended by the contractor, Tenant shall perform such
repairs and/or replacements and shall provide Landlord with evidence that such
repairs and/or replacements have been completed in accordance with the
contractor's recommendations. Landlord may, at Landlord's election, have the
HVAC systems inspected by Landlord's contractor on a semiannual basis to confirm
whether Tenant has maintained the HVAC systems as required herein. The cost of
any such semi-annual inspections shall be included in Building Maintenance
Expenses and paid for by Tenant as provided in Paragraph 17.C. Notwithstanding
the foregoing to the contrary, Landlord shall have the right at any time during
the term of this Lease to assume Tenant's obligations to maintain and repair the
HVAC systems, as those

                                      11
<PAGE>
 
obligations as specified above in this Paragraph 17.B., upon written notice to
Tenant and, if Landlord elects to do so, the cost of such maintenance and
repair, including any service contracts maintained by Landlord for such purpose,
shall be included in Building Maintenance Expenses and paid by Tenant as
provided in Paragraph 17.C.

                    ----------------  
Tenant shall pay to Landlord on the first day of each calendar month of the Term
Tenant's Percentage of the estimated monthly Operating Expenses incurred by
Landlord. The foregoing estimated monthly charges may be adjusted by Landlord at
the end of any calendar quarter on the basis of Landlord's experience and
reasonably anticipated costs. Any such adjustment shall be effective as of the
calendar month next succeeding receipt by Tenant of written notice of such
adjustment. Within one hundred twenty (120) days following the end of each
calendar year Landlord shall furnish Tenant a statement of such actual expenses
("Actual Expenses") for the calendar year and the payments made by Tenant with
respect to such period. If Tenant's payments for the Operating Expenses do not
equal the amount of the Actual Expenses, Tenant shall pay Landlord the
deficiency within thirty (30) days after receipt of such statement. If Tenant's
payments exceed the Actual Expenses, Landlord shall offset the excess against
the Operating Expenses thereafter becoming due to Landlord. There shall be
appropriate adjustments of the Operating Expenses as of the Commencement Date
and expiration of the Term.

              D.    COMPLIANCE WITH GOVERNMENTAL REGULATIONS. Tenant shall, at
                    ----------------------------------------

     18.  LIENS.  Tenant shall keep the Building and the Project free from any
liens arising out of any work performed, materials furnished or obligations
incurred by or on behalf of Tenant and shall indemnify, defend and hold Landlord
and its Agents harmless from all claims, costs and liabilities, including
attorneys' fees and costs, in connection with or arising out of any such lien or
claim of lien.  Tenant shall cause any such lien imposed to be released of
record by payment or posting of a proper bond acceptable to Landlord within ten
(10) days after receipt by Tenant of written request by Landlord.  Tenant shall
give Landlord written notice of Tenant's intention to perform work on the
Premises which might result in any claim of lien at least ten (10) days prior to
the commencement of such work to enable Landlord to post and record a Notice of
Nonresponsibility.  If Tenant fails to so remove any such lien within the
prescribed ten (10) day period, then Landlord may do so at Tenant's expense and
Tenant shall reimburse Landlord for such amounts upon demand.  Such
reimbursement shall include all costs incurred by Landlord including Landlord's
reasonable attorneys' fees with interest thereon at the Interest Rate.

     19.  LANDLORD'S RIGHT TO ENTER THE PREMISES.  Tenant shall permit Landlord
and its Agents to enter the Premises at all reasonable times with reasonable

obligations hereunder when Tenant has failed to do so within a reasonable time
after written notice from Landlord, and at any reasonable time within one
hundred and eighty (180) days prior to the expiration or earlier termination of
the Term, to place upon the Building and the Outside Area ordinary "For Lease"
signs and to show the Premises to prospective tenants.  The above rights are
subject to reasonable security regulations of Tenant, and to the requirement
that Landlord shall at all times act in a manner to cause the least possible
physical interference with Tenant's business.

     20.  SIGNS.  The location, size, design, color and other physical aspects
of Tenant's identification signage shall comply with the sign criteria for the
Project attached as EXHIBIT F and shall be subject to the Landlord's written
                    ---------                                               
approval prior to installation (which shall not be unreasonably withheld), the
CC&Rs, and any appropriate municipal or other governmental approvals.  The cost
of the sign, its installation, maintenance and removal expense shall be Tenant's
sole expense.  If Tenant fails to maintain its sign, or, if Tenant fails to
remove its sign upon termination of this Lease, Landlord may do so at Tenant's
expense and Tenant's reimbursement to Landlord for such amounts shall be deemed
Additional Rent.

     21.  INSURANCE.

          A.  INDEMNIFICATION.  Tenant hereby agrees to defend, indemnify and
              ---------------                                                
hold harmless Landlord an its Agents from and against any and all claims,
damage, loss, liability or expense including attorneys' fees and legal costs
suffered directly or by reason of any claim, suit or judgment brought by or in
favor of any person or persons for damage, loss or expense due to, but not
limited to, bodily injury and property damage sustained by such person or
persons which arises out of, is occasioned by or in any way attributable to the
use or occupancy of the Premises or the Project or any part thereof and adjacent
areas by Tenant, the acts or omissions of the Tenant, its agents, employees or
any contractors brought onto the Premises or the Project by Tenant, except to
the extent caused by the negligence or willful misconduct of Landlord or its
Agents.  Tenant agrees that the obligations assumed herein shall survive the
termination or expiration of this Lease.  The foregoing indemnity shall not
apply, however, to any claims, damage, loss, liability or expense arising out of
or in connection with the presence of any Hazardous Materials in, on or about
the Project, which indemnity shall be governed solely by the provisions of
Paragraph 11.D.

          B.  TENANT'S INSURANCE.  Tenant agrees to maintain in full force and
              ------------------                                              
effect at all times during the Term, at its own expense, for the protection of
Tenant and Landlord, as their interests may appear, policies of insurance issued
by a responsible carrier or carriers acceptable to Landlord which afford the
following coverages:

              (i)   Commercial general liability insurance in an amount not less
than Five Million and no/100ths Dollars ($5,000,000.00) combined single limit

                                      14
<PAGE>
 
              (ii)  "Special Form" property insurance (including, without
limitation, vandalism, malicious mischief, inflation endorsement, and sprinkler
leakage endorsement) on Tenant's Personal Property located on or in the
Premises. Such insurance shall be in the full amount of the replacement cost, as
the same may from time to time increase as a result of inflation or otherwise,
and shall be in a form providing coverage comparable to the coverage provided in
the standard ISO "Special Form" form. As long as this Lease is in effect, the
proceeds of such policy shall be used for the repair and replacement of such
items so insured. Landlord shall have no interest in the insurance proceeds on
Tenant's Personal Property.

          C.  PREMISES INSURANCE.  During the Term Landlord shall maintain
              ------------------                                          
"Special Form" property insurance (including inflation endorsement, sprinkler
leakage endorsement and, at Landlord's option, boiler and machinery insurance,
earthquake and flood coverage) on the Building, excluding coverage of all
Tenant's Personal Property located on or in the Premises.  Such insurance shall
also include insurance against loss of rents on a "Special Form" basis,
including, at Landlord's option, earthquake and flood, in an amount equal to the
Monthly Rent and Additional Rent, and any other sums payable under the Lease,
for a period of at least twelve (12) months commencing on the date of loss.
Such insurance shall name Landlord and its Agents as named insureds and include
a lender's loss payable endorsement in favor of Landlord's lender (Form 438 BFU
Endorsement).  If the Project insurance premiums are increased after the
Commencement Date, due to an increase in the value of the Building or its
replacement cost, Tenant shall pay Tenant's Percentage of such increase within
ten (10) days of notice of such increase.  If such insurance premiums are
increased due to Tenant's use of the Premises, improvements installed by Tenant,
or any other cause solely attributable to Tenant, Tenant shall pay the full
amount of the increase.

          D.  WAIVER OF SUBROGATION.  Landlord and Tenant each hereby waive all
              ---------------------                                            
rights of recovery against the other on account of loss or damage occasioned to
such waiving party for its property or the property of others under its control
to the extent that such loss or damage is insured against under any insurance
policies which may be in force at the time of such loss or damage.  Tenant and
Landlord shall, upon obtaining policies of insurance required hereunder, give
notice to the insurance carrier that the foregoing mutual waiver of subrogation
is contained in this Lease and Tenant and Landlord shall cause each insurance
policy obtained by such party to provide that the insurance company waives all
right of recovery by way of subrogation against either Landlord or Tenant in
connection with any damage covered by such policy.

          E.  INCREASED COVERAGE.  Upon demand, Tenant shall provide Landlord,
              ------------------                                              
at Tenant's expense, with such increased amount of existing insurance, and such
other insurance as Landlord or Landlord's lender may reasonably require to
afford Landlord and Landlord's lender adequate protection.

          F.  CO-INSURER.  If, on account of the failure of Tenant to comply
              ----------                                                    
with the foregoing provisions, Landlord is adjusted a co-insurer by its
insurance carrier, then, any loss or damage Landlord shall sustain by reason
thereof, including attorneys' fees and costs, shall be borne by Tenant and shall
be immediately paid by Tenant upon receipt of a bill therefor and evidence of
such loss.

                                      15
<PAGE>
 
          G.  INSURANCE REQUIREMENTS.  All insurance shall be in a form
              ----------------------                                   
satisfactory to Landlord and shall be carried with companies that have a general
policy holder's rating of not less than "A" and a financial rating of not less
than Class "X" in the most current edition of Best's Insurance Reports; shall
                                              ------------------------       
provide that such policies shall not be subject to material alteration or
cancellation except after at least thirty (30) days' prior written notice to
Landlord; and shall be primary as to Landlord.  The policy or policies, or duly
executed certificates for them, together with satisfactory evidence of payment
of the premium thereon shall be deposited with Landlord prior to the
Commencement Date, and upon renewal of such policies, not less than thirty (30)
days prior to the expiration of the term of such coverage.  If Tenant fails to
procure and maintain the insurance required hereunder, Landlord may, but shall
not be required to, order such insurance at Tenant's expense and Tenant shall
reimburse Landlord.  Such reimbursement shall include all costs incurred by
Landlord including Landlord's reasonable attorneys' fees, with interest thereon
at the Interest Rate.

          H.  LANDLORD'S DISCLAIMER.  Landlord and its Agents shall not be
              ---------------------                                       
liable for any loss or damage to persons or property resulting from fire,
explosion, falling plaster, glass, tile or sheetrock, steam, gas, electricity,
water or rain which may leak from any part of the Building or from the pipes,
appliances or plumbing works therein or from the roof, street or subsurface, or
any other cause whatsoever, unless caused by or due to the sole negligence or
willful acts of Landlord.  Tenant shall give prompt written notice to Landlord
to case of a casualty, accident or repair needed in the Premises.

     22.  DAMAGE OR DESTRUCTION.

          A.  LANDLORD'S OBLIGATION TO REBUILD.  If the Premises or the Building
              --------------------------------                                  
is damaged or destroyed, Landlord shall promptly and diligently repair the same
unless either Landlord or Tenant has the right to terminate this Lease as
provided herein and either party has elected to so terminate.

          B.  RIGHT TO TERMINATE.  Landlord shall have the right to terminate
              ------------------                                             
this Lease in the event any of the following events occurs:

              (i)   Insurance proceeds are not available to pay one hundred
percent (100%) of the cost of such repair, excluding the deductible for which
Tenant shall be responsible ;

              (ii)  The Premises cannot, with reasonable diligence, be fully
repaired by Landlord within one hundred twenty (120) days after the date of the
damage or destruction; or

              (iii) The Premises cannot be safety repaired because of the
presence of hazardous factors, including, but not limited to, earthquake faults,
radiation, chemical waste and other similar dangers.

          If Landlord elects to terminate this Lease, Landlord shall give Tenant
written notice of its election to terminate within thirty (30) days after such
damage or destruction, and this Lease shall terminate fifteen (15) days after
the date Tenant receives such notice. If Landlord elects not to terminate the
Lease, subject to Tenant's termination right set forth below, Landlord

                                      16
<PAGE>
 
shall promptly commence the process of obtaining necessary permits and approvals
and repair of the Premises or the Building as soon as practicable, and this
Lease will continue in full force and effect. All insurance proceeds from
insurance under Paragraph 21, excluding proceeds for Tenant's Personal Property,
shall be disbursed and paid to Landlord. Tenant shall be required to pay to
Landlord the amount of any deductibles payable in connection with any insured
casualties, unless the casualty was caused by the sole negligence or willful
misconduct of Landlord.

          Tenant shall have the right to terminate this Lease, if the Premises
cannot, with reasonable diligence and subject to Tenant delays, be fully
repaired within one hundred eighty (180) days from the date of damage or
destruction. The determination of the estimated repair period shall be made by
Landlord in its good faith business judgment within thirty (30) days after such
damage or destruction. Landlord shall deliver written notice of the repair
period to Tenant after such determination has been made and Tenant shall
exercise its right to terminate this Lease, if at all, within ten (10) days of
receipt of such notice from Landlord. If this Lease is terminated by either
party as permitted herein, Landlord shall refund to Tenant any prepaid Rent
allocable to the period following the date of the casualty.

          C.  LIMITED OBLIGATION TO REPAIR.  Landlord's obligation, should it
              ----------------------------                                   
elect or be obligated to repair or rebuild, shall be limited to the Premises or
the Building, as the case may be, as any or all of the same existed immediately
prior to the casualty, excluding, however, any additional alterations or
improvements made by Tenant.

          D.  ABATEMENT OF RENT.  Rent shall be temporarily abated
              -----------------                                   
proportionately during any period when, by reason of such damage or destruction,
Landlord and Tenant reasonably determine that there is substantial interference
with Tenant's use of the Premises, having regard to the extent to which Tenant
may be required to discontinue Tenant's use of the Premises. Such abatement
shall commence upon such damage or destruction and end upon substantial
completion by Landlord of the repair or reconstruction which Landlord is
obligated or undertakes to do. Tenant shall not be entitled to any other
compensation or damages from Landlord for loss of the use of the Premises,
damage to Tenant's Personal Property or any inconvenience occasioned by such
damage, repair or restoration. Tenant hereby waives the provisions of Section
1932, Subdivision 2, and Section 1933, Subdivision 4, of the California Civil
Code and the provisions of any similar law hereinafter enacted.

          E.  DAMAGE NEAR END OF TERM. Anything herein to the contrary
              -----------------------                                 
notwithstanding, if there is any significant destruction of or damage to the
Premises or the Building during the last twelve (12) months of the Term, then
Landlord or Tenant may, at its option, cancel and terminate this Lease as of the
date of the occurrence of such damage. If neither Landlord nor Tenant elects to
so terminate this Lease, the repair of such damage shall be governed by
Paragraphs 22.A. and 22.B. For purposes of this Paragraph 22.E., "significant"
destruction or damage shall mean destruction or damage which cannot reasonably
be repaired within sixty (60) days after the date the destruction or damage
occurs.

     23.  CONDEMNATION.  If title to all of the Premises or Building or so much
thereof is taken for any public or quasi-public use under any statute or by
right of eminent domain so that reconstruction of the Premises or Building will
not, in Landlord's and Tenant's

                                      17
<PAGE>
 
mutual opinion, result in the Premises being reasonably suitable for Tenant's
continued occupancy for the uses and purposes permitted by this Lease, this
Lease shall terminate as of the date that possession of the Premises or Building
or part thereof be taken, and Landlord shall refund to Tenant any prepaid Rent
allocable to the period following the date of the taking. A sale by Landlord to
any authority having the power of eminent domain, either under threat of
condemnation or while condemnation proceedings are pending, shall be deemed a
taking under the power of eminent domain for all purposes of this paragraph.

          If any part of the Premises or Building is taken and the remaining
part is reasonably suitable for Tenant's continued occupancy for the purposes
and uses permitted by this Lease, this Lease shall, as to the part so taken,
terminate as of the date that possession of such part of the Premises or
Building is taken. The Rent and other sums payable hereunder shall be reduced in
the same proportion that Tenant's use and occupancy of the Premises is reduced.
If any portion of the Outside Area is taken, Tenant's Rent shall be reduced only
if such taking materially interferes with Tenant's use of the Outside Area and
then only to the extent that the fair market rental value of the Premises is
diminished by such partial taking. If the parties disagree as to the amount of
Rent reduction, the matter shall be resolved by arbitration and such arbitration
shall comply with and be governed by the California Arbitration Act, Sections
1280 through 1294.2 of the California Code of Civil Procedure. Each party hereby
waives the provisions of Section 1265.130 of the California Code of Civil
Procedure allowing either party to petition the Superior Court to terminate this
Lease in the event of a partial taking of the Project or Premises.

          No award for any partial or entire taking shall be apportioned. Tenant
assigns to Landlord its interest in any award which may be made in such taking
or condemnation, together with any and all rights of Tenant arising in or to the
same or any part thereof. Nothing contained herein shall be deemed to give
Landlord any interest in or require Tenant to assign to Landlord any separate
award made to Tenant for the taking of Tenant's Personal Property, for the
interruption of Tenant's business, its moving costs, or costs associated with
obtaining new premises to conduct the business being conducted in the Premises.

     24.  ASSIGNMENT AND SUBLETTING.

          A.  LANDLORD'S CONSENT.  Tenant shall not enter into a Sublet without
              ------------------                                               
Landlord's prior written consent, which consent shall not be unreasonably
withheld. Any attempted or purported Sublet without Landlord's prior written
consent shall be void and confer no rights upon and third person and, at
Landlord's election, shall terminate this Lease. Each Subtenant shall agree in
writing, for the benefit of Landlord, to assume, to be bound by, and to perform
the terms, conditions and covenants of this Lease to be performed by Tenant.
Notwithstanding anything contained herein, Tenant shall not be released from
liability for the performance of each term, condition and covenant of this Lease
by reason of Landlord's consent to a Sublet unless Landlord specifically grants
such release in writing.

          B.  INFORMATION TO BE FURNISHED.  If Tenant desires at any time to
              ---------------------------                                   
Sublet the Premises or any portion thereof, it shall first notify Landlord of
its desire to do so and shall submit in writing to Landlord: (i) the name and
identity of the proposed Subtenant; (ii) the nature

                                      18
<PAGE>
 
of the proposed Subtenant's business to be carried on in the Premises; (iii) the
terms and provisions of the proposed Sublet and a copy of the proposed Sublet
form containing a description of the subject premises; and (iv) such financial
information, including financial statements, as Landlord may reasonable request
concerning the proposed Subtenant.

          C.  LANDLORD'S ALTERNATIVES. Within thirty (30) days after Landlord's
              -----------------------                                          
receipt of the information specified in Paragraph 24.B., Landlord shall, by
written notice to Tenant, elect: (i) terminate this Lease as of the commencement
date stated in the proposed Sublet; (ii) acquire from Tenant the interest, or
any portion thereof, in this Lease and/or the Premises which is the subject of
the proposed Sublet, on the same terms and conditions as stated in the proposed
Sublet: (iii) to consent to the Sublet by Tenant; or (iv) to reasonably withhold
its consent to the Sublet. If Landlord proceeds under Paragraph 24.C.(iii) and
consents to the Sublet, Tenant may thereafter enter into a valid Sublet of the
Premises or portion thereof, upon the terms and conditions and with the proposed
Subtenant set forth in the information furnished by Tenant to Landlord pursuant
to Paragraph 24.B., subject, however, at Landlord's election, to the condition
that any excess of the Subrent over the Rent required to be paid by Tenant under
this Lease less reasonable attorneys' fees and leasing commissions paid by
Tenant on the Sublease, shall be paid to Landlord.

          D.  PRORATION.  For the purposes of determining the excess Subrent
              ---------                                                     
payable to Landlord pursuant to Paragraph 24.C, if a portion of the Premises is
Sublet, the pro rata share of the Rent attributable to such partial area of the
Premises shall be determined by Landlord by dividing the Rent payable by Tenant
hereunder by the total square footage of the Premises and multiplying the
resulting quotient (the per square foot rent) by the number of square feet of
the Premises which are Sublet.

          E.  EXEMPT SUBLETS.  Notwithstanding the above, Landlord's prior
              --------------                                              
written consent shall not be required for an assignment of this Lease to a
subsidiary, affiliate or parent corporation of Tenant, or a corporation into
which Tenant merges or consolidates, if Tenant gives Landlord prior written
notice of the name of any such assignee, and if the assignee assumes, in
writing, for the benefit of Landlord all of Tenant's obligations under the
Lease. An assignment or other transfer of this Lease to a purchaser of all or
substantially all of the assets of Tenant shall be deemed a Sublet requiring
Landlord's prior written consent.

     25.  DEFAULT.

          A.  TENANT'S DEFAULT.  A default under this Lease by Tenant shall
              ----------------                                             
exist if any of the following occurs:

              (i)   If Tenant fails to pay Rent or any other sum required to be
paid hereunder when due; or

              (ii)  If Tenant fails to perform any term, covenant or condition
of this Lease except those requiring the payment of money, and Tenant fails to
cure such breach within fifteen (15) days after written notice from Landlord
where such breach could reasonably be cured within such fifteen (15) day period;
provided, however, that where such failure could not 

                                      19
<PAGE>
 
reasonably be cured within the fifteen (15) day period, that Tenant shall not be
in default if it commences such cure within the fifteen (15) day period and
thereafter diligently prosecutes same to completion. which completion shall
occur not later than sixty (60) days from the date of receipt of written notice
from Landlord; or

              (iii) If Tenant assigns its assets for the benefit of its
creditors; or

              (iv)  If the sequestration or attachment of or execution on any
material part of Tenant's Personal Property essential to the conduct of Tenant's
business occurs, and Tenant fails to obtain a return or release of such Personal
Property within thirty (30) days thereafter, or prior to sale pursuant to such
sequestration, attachment or levy, whichever is earlier; or

              (v)   If Tenant abandons or vacates the Premises; provided,
however, Tenant's vacation of the Premises with prior written notice to Landlord
shall not be deemed to be a default hereunder as long as during such vacation
Tenant pays all Rent due under this Lease and performs all other obligations
required to be performed by Tenant under this Lease; or

              (vi)  If a court of competent jurisdiction makes or enters any
decree or order other than under the bankruptcy laws of the United States
adjudging Tenant to be insolvent; or approving as properly filed a petition
seeking reorganization of Tenant; or directing the winding up or liquidation of
Tenant and such decree or order shall have continued for a period of thirty (30)
days.

          B.  REMEDIES.  Upon a default, Landlord shall have the following
              --------                                                    
remedies, in addition to all other rights and remedies provided by law or
otherwise provided in this Lease, to which Landlord may resort cumulatively or
in the alternative:

              (i)   Landlord may continue this Lease in full force and effect,
and this Lease shall continue in full force and effect as long as Landlord does
not terminate this Lease, and Landlord shall have the right to collect Rent when
due.

              (ii)  Landlord may terminate Tenant's right to possession of the
Premises at any time by giving written notice to that effect, and relet the
Premises or any part thereof. Tenant shall be liable immediately to Landlord for
all costs Landlord incurs in reletting the Premises or any part thereof,
including, without limitation, broker's commissions, expenses of cleaning and
redecorating the Premises required by the reletting and like costs. Reletting
may be for a period shorter or longer than the remaining term of this Lease. No
act by Landlord other than giving written notice to Tenant shall terminate this
Lease. Acts of maintenance, efforts to relet the Premises or the appointment of
a receiver on Landlord's initiative to protect Landlord's interest under this
Lease shall not constitute a termination of Tenant's right to possession. On
termination, Landlord has the right to remove all Tenant's Personal Property and
store the same at Tenant's cost and to recover from Tenant as damages:

              (a)   The worth at the time of award of unpaid Rent and other sums
due and payable which had been earned at the time of termination; plus

                                      20
<PAGE>
 
              (b)   The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable which would have been payable after
termination until the time of award exceeds the amount of such Rent loss that
Tenant prove could have been reasonably avoided; plus

              (c)   The worth at the time of award of the amount by which the
unpaid Rent and other sums due and payable for the balance of the Term after the
time of award exceeds the amount of such Rent loss that Tenant proves could be
reasonably avoided; plus

              (d)   Any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform Tenant's
obligations under this Lease, or which, in the ordinary course of things, would
be likely to result therefrom, including, without limitation, any costs or
expenses incurred by Landlord: (i) in retaking possession of the Premises; (ii)
in maintaining, repairing, preserving, restoring, replacing, cleaning, altering
or rehabilitating the Premises or any portion thereof, including such acts for
reletting to a new tenant or tenants; (iii) for leasing commissions; or (iv) for
any other costs necessary or appropriate to relet the Premises; plus

              (e)   At Landlord's election, such other amounts in addition to or
in lieu of the foregoing as may be permitted from time to time by the laws of
the State of California.

          The "worth at the time of award" of the amounts referred to in
Paragraphs 25.B.(ii)(a) and 25.B.(ii)(b) is computed by allowing interest at the
Interest Rate on the unpaid rent and other sums due and payable from the
termination date through the date of award. The "worth at the time of award" of
the amount referred to in Paragraph 25.B.(ii)(c) is computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus one percent (1%). Tenant waives redemption or relief from
forfeiture under California Code of Civil Procedure Sections 1174 and 1179, or
under any other present or future law, in the event Tenant is evicted or
Landlord takes possession of the Premises by reason of any default of Tenant
hereunder.

          (iii) Landlord may, with or without terminating this Lease, re-
enter the Premises and remove all persons and property from the Premises; such
property may be removed and stored in a public warehouse or elsewhere at the
cost of and for the account of Tenant. No reentry or taking possession of the
Premises by Landlord pursuant to this paragraph shall be construed as an
election to terminate this Lease unless a written notice of such intention is
given to Tenant.

          C.  BANKRUPTCY.
              ---------- 

              (i)   The commencement of a bankruptcy action or liquidation
action or reorganization action or insolvency action or an assignment of or by
Tenant for the benefit of creditors, or any similar action undertaken by Tenant,
or the insolvency of Tenant, shall, at Landlord's option, constitute a breach of
this Lease by Tenant. If the trustee or receiver appointed to serve during a
bankruptcy, liquidation, reorganization, insolvency or similar action elects to
reject Tenant's unexpired Lease, the trustee or receiver shall notify Landlord
in writing of its 

                                      21
<PAGE>
 
election within thirty (30) days after an order for relief in a liquidation
action or within thirty (30) days after the commencement of any action.

               (ii)  Within thirty (30) days after court approval of the
assumption of this Lease, the trustee or receiver shall cure (or provide
adequate assurance to the reasonable satisfaction of Landlord that the trustee
or receiver shall cure) any and all previous defaults under the unexpired Lease
and shall compensate Landlord for all actual pecuniary loss resulting from
Tenant's breach of this Lease, including any attorneys' fees and costs incurred
by Landlord as a result of such breach and/or the bankruptcy proceedings
instituted by or against Tenant, and shall provide adequate assurance of future
performance under the Lease to the reasonable satisfaction of Landlord. Adequate
assurance of future performance, as used herein, includes, but shall not be
limited to: (i) assurance of source and payment of Rent, and other consideration
due under this Lease; (ii) assurance that the assumption or assignment of this
Lease will not breach any provision, such as radius, location, use, or
exclusivity provision, in any other lease of space within the Complex.

               (iii) Nothing contained in this section shall affect the right of
Landlord to refuse to accept an assignment upon commencement of or in connection
with a bankruptcy, liquidation, reorganization or insolvency action or an
assignment of Tenant for the benefit of creditors or other similar act. Nothing
contained in this Lease shall be construed as giving or granting or creating an
equity in the Premises to Tenant. In no event shall the leasehold estate under
this Lease, or any interest therein, be assigned by voluntary or involuntary
bankruptcy proceeding without the prior written consent of Landlord. In no event
shall this Lease or any rights or privileges hereunder be an asset of Tenant
under any bankruptcy, insolvency or reorganization proceedings.

          D.   LANDLORD'S DEFAULT.  Landlord shall not be deemed to be in
               ------------------                                        
default in the performance of any obligation required to be performed by it
hereunder unless and until it has failed to perform such obligation within
thirty (30) days after receipt of written notice by Tenant to Landlord
specifying the nature of such default; provided, however, that if the nature of
Landlord's obligation is such that more than thirty (30) days are required for
its performance, then Landlord shall not be deemed to be in default if it shall
commence such performance within such thirty (30) day period and thereafter
diligently prosecute the same to completion.

     26.  SUBORDINATION.  This Lease is subject and subordinate to mortgages
and deeds of trust (collectively "Encumbrances") which may now affect the
Building or the Project, to the CC&Rs and to all renewals, modifications,
consolidations, replacements and extensions thereof; provided, however, if the
holder or holders of any such Encumbrance ("Holder") shall require that this
Lease be prior and superior thereto, Tenant shall, within seven (7) days after
written request from Landlord, execute, have acknowledged and deliver any and
all reasonable documents or instruments, which Landlord or Holder deems
necessary or desirable for such purposes. Landlord shall have the right to cause
this Lease to be and become and remain subject and subordinate to any and all
Encumbrances which are now or may hereafter be executed covering the Building or
the Project or any renewals, modifications, consolidations, replacements or
extensions thereof, for the full amount of all advances made or to be made
thereunder and without regard to the time or character of such advances,
together with interest thereon and

                                      22
<PAGE>
 
subject to all the terms and provisions thereof; provided only, that in the
event of termination of any such lease or upon the foreclosure of any such
mortgage or deed of trust, so long as Tenant is not in default, Holder agrees to
recognize Tenant's rights under this Lease as long as Tenant shall pay the Rent
and observe and perform all the provisions of this Lease to be observed and
performed by Tenant. Within ten (10) days after Landlord's written request,
Tenant shall execute any and all documents required by Landlord or the Holder to
make this Lease subordinate to any lien of the Encumbrance. If Tenant fails to
do so, it shall be deemed that this Lease is subordinated. Notwithstanding
anything to the contrary set forth in this paragraph, Tenant hereby attorns and
agrees to attorn to any entity purchasing or otherwise acquiring the Building or
the Project at any sale or other proceeding or pursuant to the exercise of any
other rights, powers or remedies under such Encumbrance.

     27.  NOTICES.  Any notice or demand required or desired to be given under
this Lease shall be in writing and shall be personally served or in lieu of
personal service may be given by mail. If given by mail, such notice shall be
deemed to have been given when seventy-two (72) hours have elapsed from the time
when such notice was deposited in the United States mail, registered or
certified, and postage prepaid, addressed to the party to be served. At the date
of execution of this Lease, the addresses of Landlord and Tenant are as set
forth in Paragraph 1. After the Commencement Date, the address of Tenant shall
be the address of the Premises. Either party may change its address by giving
notice of same in accordance with this paragraph.

     28.  ATTORNEYS' FEES. If either party brings any action or legal proceeding
for damages for an alleged breach of any provision of this Lease, to recover
rent, or other sums due, to terminate the tenancy of the Premises or to enforce,
protect or establish any term, condition or covenant of this Lease or right of
either party, the prevailing party shall be entitled to recover as a part of
such action or proceedings, or in a separate action brought for that purpose,
reasonable attorneys' fees and costs.

     29.  ESTOPPEL CERTIFICATES; FINANCIAL STATEMENTS. Tenant shall within ten
(10) days following written request by Landlord:

          (i)  Execute and deliver to Landlord any documents, including estoppel
certificates, in the form prepared by Landlord (a) certifying that this Lease is
unmodified and in full force and effect or, if modified, stating the nature of
such modification and certifying that this Lease. as so modified, is in full
force and effect and the date to which the Rent and other charges are paid in
advance, if any, and (b) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord, or, if there are
uncured defaults on the part of the Landlord, stating the nature of such uncured
defaults, and (c) evidencing the status of the Lease as may be required either
by a lender making a loan to Landlord to be secured by deed of trust or mortgage
covering the Building or the Project or a purchaser of the Building or the
Project from Landlord. Tenant's failure to deliver an estoppel certificate
within seven (7) days after delivery of Landlord's written request therefor
shall be conclusive upon Tenant (a) that this Lease is in full force and effect,
without modification except as may be represented by Landlord, (b) that there
are now no uncured defaults in Landlord's performance and (c) that no Rent has
been paid in advance. If Tenant fails to so deliver a requested estoppel
certificate within the

                                      23
<PAGE>
 
prescribed time it shall be conclusively presumed that the Lease is unmodified
and in full force and effect except as represented by Landlord.

          (ii)  Deliver to Landlord the current financial statements of Tenant
and financial statements of the two (2) years prior to the current financial
statements year, to the extent that such financial statements exist, certified
by an officer of the Tenant, including, if they exist, a balance sheet and
profit and loss statement for the most recent prior year, all prepared in
accordance with generally accepted accounting principles consistently applied.

     30.  TRANSFER OF THE BUILDING OR PROJECT BY LANDLORD.  In the event of any
conveyance of the Building or the Project and assignment by Landlord of this
Lease, Landlord shall be and is hereby entirely released from all liability
under any and all of its covenants and obligations contained in or derived from
this Lease occurring after the date of such conveyance and assignment and Tenant
agrees to attorn to such transferee provided such transferee assumes Landlord's
obligations under this Lease.

     31.  LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS.  If Tenant shall at
any time fail to make any payment or perform any other act on its part to be
made or performed under this Lease, Landlord may, but shall not be obligated to
and without waiving or releasing Tenant from any obligation of Tenant under this
Lease, upon written notice to Tenant, make such payment or perform such other
act to the extent Landlord may deem desirable, and in connection therewith, pay
expenses and employ counsel. All sums so paid by Landlord and all penalties,
interest and costs in connection therewith shall be due and payable by Tenant on
the next day after any such payment by Landlord, together with interest thereon
at the Interest Rate from such date to the date of payment by Tenant to
Landlord, plus collection costs and attorneys' fees. Landlord shall have the
same rights and remedies for the nonpayment thereof as in the case of default in
the payment of Rent.

     32.  LIMITATION OF LIABILITY.  In consideration of the benefits accruing
hereunder, Tenant and all successors and assigns covenant and agree that, in the
event of any actual or alleged failure, breach or default hereunder by Landlord:

          (i)   The sole and exclusive remedy shall be against the Landlord's
interest in the Project, including the Building;

          (ii)  No partner of Landlord shall be sued or named as a party in any
suit or action (except as may be necessary to secure jurisdiction of the
partnership);

          (iii) No service of process shall be made against any partner of
Landlord (except as may be necessary to secure jurisdiction of the partnership);

          (iv)  No partner of Landlord shall be required to answer or otherwise
plead to any service of process;

          (v)   No judgment will be taken against any partner of Landlord;

                                      24
<PAGE>
 
          (vi)   Any judgment taken against any partner of Landlord may be
vacated and set aside at any time nunc pro tunc;

          (vi)   No writ of execution will ever be levied against the assets of
any partner of Landlord;

          (viii) These covenants and agreements are enforceable both by
Landlord and also by any partner of Landlord.

     33.  MORTGAGEE PROTECTION.  If Landlord defaults under this Lease, Tenant
will notify any beneficiary of a deed of trust or mortgagee of a mortgage
covering the Building or the Project for which Landlord has provided Tenant with
a name and address, and offer such beneficiary or mortgagee a reasonable
opportunity to cure the default, including time to obtain possession of the
Building or the Project by power of sale or a judicial foreclosure, if such
should prove necessary to effect a cure.

     34.  BROKERS.  Landlord and Tenant warrant and represent each to the other
that it has had no dealings with any real estate broker or agent in connection
with the negotiation of this Lease, except for Cornish & Carey Commercial and BT
Commercial whose commissions shall be payable by Landlord, and that it knows of
no other real estate broker or agent who is or might be entitled to a commission
in connection with this Lease. Landlord and Tenant agree to indemnify, defend
and hold each other and their respective agents harmless from and against any
and all liabilities or expenses, including attorneys' fees and costs, arising
out of or in connection with claims made by any broker or individual for
commissions or fees resulting from the execution of this Lease.

     35.  ACCEPTANCE.  This Lease shall only become effective and binding upon
full execution hereof by Landlord and delivery of a signed copy to Tenant.
Neither party shall record this Lease nor a short form memorandum thereof.

     36.  MODIFICATION FOR LENDER.  If in connection with obtaining financing
for the Building or the Project or any portion thereof, Landlord's lender shall
request reasonable modification to this Lease as a condition to such financing,
Tenant shall not unreasonably withhold, delay or defer its consent thereto,
provided such modifications do not materially adversely affect Tenant's rights
hereunder.

     37.  PARKING.  Tenant shall have the right to use up to fifty-seven (57)
unreserved parking spaces in the Project's parking facilities in common with
other tenants of the Project upon terms and conditions, as may from time to time
be established by Landlord. Tenant agrees not to overburden the parking
facilities and agrees to cooperate with Landlord and other tenants in the use of
the parking facilities. Landlord reserves the right in its discretion to
determine whether the parking facilities are becoming crowded and to allocate
and assign parking spaces among Tenant and the other tenants. Tenant shall not
park cars, trucks, trailers or other vehicles, or parts thereof, overnight on
the Project.

                                      25
<PAGE>
 
     38.  CONDITION.  The effectiveness of this Lease and the rights and
obligations of Landlord and Tenant hereunder shall be conditioned upon Landlord
and the existing tenant of the Premises entering into a written lease
termination agreement on terms and in form satisfactory to Landlord in its sole
and absolute discretion. This condition shall be satisfied, if at all, by April
30, 1996. In the event the condition is not satisfied as and when required, then
this Lease shall not be effective and Landlord and Tenant shall have no rights
or obligations hereunder.

condition and covenant of this Lease.

          D .  SEPARABILITY. If one or more of the provisions contained herein,
               ------------                                                    
except for the payment of Rent, is for any reason held invalid, illegal or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provision of this Lease, but this Lease shall be
construed as if such invalid, illegal or unenforceable provision had not been
contained herein.

          E.   CHOICE OF LAW. This Lease shall be construed and enforced in
               -------------                                               
accordance with the substantive laws of the State of California. The language in
all parts of this Lease shall in all cases be construed as a whole according to
its fair meaning and not strictly for or against either Landlord or Tenant.

               ------------------------                                
requires, the neuter gender includes the masculine, the feminine, a partnership
or corporation or joint venture, and the singular includes the plural.

be a waiver of such provision or any subsequent breach of the same or any other

at the time of acceptance of such payment. No covenant, term or condition of
this Lease shall be deemed to have been waived by Landlord or Tenant unless such
waiver is in writing signed by the waiving party.

                              W I T N E S S E T H
                              - - - - - - - - - -

          Landlord hereby leases to Tenant and Tenant hereby rents from Landlord
(a) the portion of the fourth (4th) floor shown hatched on the plans annexed
hereto as Schedule A-I in the building known as Plaza II (the "Fourth Floor
Space"), and (b) the portion of the eighth (8th) floor shown hatched on the
plans annexed hereto as Schedule A-II in the building known as Plaza III (the
"Eighth Floor Space," the Fourth Floor Space and the Eighth Floor Space are
collectively the "Demised Premises"), in the office complex (the "Complex")
known as Harborside Financial Center consisting as of the date hereof of Plazas
I, II and III and the parking areas and other common areas serving same located
in Jersey City, New Jersey on the land (the "Land") described in Schedule B
annexed hereto (the Land together with all of the improvements now or hereafter
located thereon being hereinafter referred to as the "Property"), for a term
(the "Term'') of approximately 10 years commencing on the "Commencement Date"
and ending on the "Expiration Date" (as said terms are defined in Article 2
hereof), unless the Term shall sooner cease and terminate as hereinafter
provided.  Unless otherwise specified herein, Plazas II and III are collectively
called the ''Building.''

          The parties hereby covenant and agree as follows:

                                   ARTICLE 1

                                     RENT

          1.01.   (a)  Tenant hereby agrees to pay to Landlord a basic annual
rent (the "Basic Annual Rent") at an annual rate equal to (i) for the period
(the "First Period") commencing on the Rent Commencement Date (as such term is
defined in Article 2 hereof) and ending on the day immediately preceding the
fifth (5th) anniversary of the Rent Commencement Date, the product of (x) Twenty
and 50/100 Dollars ($20.50) multiplied by (y) the number of rentable square feet
contained in the Demised Premises, and (ii) for the period commencing on the day
after the First Period and ending on the Expiration Date, the product of (x)
Twenty-three and 00/100 Dollars ($23.00) multiplied by (y) the number of
rentable square feet contained in the Demised Premises.  Basic Annual Rent shall
be paid by Tenant in equal monthly installments in advance on the first day of
each calendar month during the Term from and after the Rent Commencement Date
(as said term is defined in Article 2 hereof), at the office of Landlord or such
other place as Landlord may designate, without any set off or deduction
whatsoever, except such deductions as are specifically referred to herein.  The
first full month's installment of Basic Annual Rent and the security deposit
described in Article 40 hereof shall be paid by Tenant to 

                                       1
<PAGE>
 
Landlord upon the execution of this Lease. Should the Rent Commencement Date
fall on any day other than the first day of a month, then the Basic Annual Rent
for such month shall be prorated on a per diem basis, and Tenant agrees to pay
the amount thereof for such partial month on the Rent Commencement Date.

                 (b)  The parties hereby acknowledge that for all purposes of
this Lease the Fourth Floor Space shall be deemed to contain 2,900 rentable
square feet, the Eighth Floor Space shall be deemed to contain 8,661 rentable
square feet and the Demised Premises shall be deemed to contain 11,561 rentable
square feet.

          1.02.  Tenant shall pay the Basic Annual Rent and all additional rent
payable hereunder in lawful money of the United States by check (subject to
collection) drawn to Landlord's order on a bank which is a member of the New
York Clearinghouse Association or a successor thereto or a New Jersey bank.  All
sums, other than Basic Annual Rent, payable by Tenant hereunder shall be deemed
additional rent and shall be payable on demand unless other payment dates are
hereinafter provided.  Landlord shall have the same right and remedies
(including, without limitation, the right to commence a summary dispossess
proceeding) for a default in the payment of additional rent as for a default in
the payment of Basic Annual Rent notwithstanding the fact that Tenant may not
then also be in default in the payment of Basic Annual Rent.

          1.03.  (a)  If Tenant shall fail to pay when due any installment of
Basic Annual Rent or any payment of additional rent and any such failure shall
continue for 5 business days, then Tenant shall pay Landlord, as additional
rent, a late charge equal to three (3%) percent of such installment or payment
as compensation for Landlord's additional administrative expenses relating to
such late payment.

                 (b)  If Tenant shall fail to pay when due any installment of
Basic Annual Rent or any payment of additional rent and such failure shall
continue beyond the 5 business day period specified in paragraph (a) above,
Tenant shall pay in addition to the late charge provided in said paragraph (a)
interest on all such amounts (including the late charge) at the Interest Rate
(as said term is defined in Article 22 hereof), from the date when such
installment or payment shall have become due to the date of payment thereof, and
such interest shall be deemed additional rent.

                 (c)  The provisions of this Section 1.03 are in addition to all
other remedies available to Landlord for nonpayment of Basic Annual Rent or
additional rent.

                                   ARTICLE 2

                                     TERM

"Commencement Date" of the Term shall be (i) the date of this Lease with respect
to the Eighth Floor Space and 

                                       2

(ii) the date that Landlord's Agent (hereinafter defined) vacates the Fourth
Floor Space in accordance with Section 2.01(b) below in the case of the Fourth
Floor Space.

                 (b)  Tenant accepts the Demised Premises in its "as is"
condition as of the Commencement Date and Landlord shall have no obligation to
perform any work or make any contribution to prepare the Demised Premises for
occupancy by Tenant. Tenant acknowledges that the Fourth Floor Space is
currently occupied by landlord's agent and its employees (collectively
"Landlord's Agent"). Landlord's Agent shall vacate the Fourth Floor Space within
fourteen (14) days after the date of this Lease.

                 (c)  The "Rent Commencement Date" shall be April 1, 1997.

                 (d)  The "Expiration Date" of the Term shall be March 31, 2007,
as the same may be extended by reason of the exercise of any extension or
renewal option contained in this Lease.

          2.02.  Except for Landlord's Work (as defined below), all
installations, materials and work which may be undertaken by Tenant to prepare,
equip, decorate and furnish the Demised Premises for Tenant's occupancy
(collectively, "Tenant's Work") shall be performed by Tenant at Tenant's expense
in accordance with Article 6 and the other applicable provisions of this Lease.

          2.03.  Landlord shall diligently perform (or cause to be performed)
the work described on Schedule C attached hereto ("Landlord's Work").

adopted as the fiscal year for real estate tax purposes for Jersey City, New
Jersey. The term "Base Tax Year" shall mean the calendar year commencing January
1, 1997.

                 (b)  The term "Taxes" shall mean (i) all real estate taxes,
assessments and special assessments, payments in lieu of any such taxes,
assessments or special assessments (including, without limitation, any payments
or charges of any kind or nature whatsoever imposed pursuant to N.J.S.A. (S)
40:55C-40 et seq. (West 1967 & Supp. 1987), as the same may be amended or
supplemented (collectively "Fox Lance Charges")), and any other governmental
levy, tax, charge or imposition (including any interest imposed thereon by
reason of Landlord's election to pay same in installments), general or special,
ordinary or extraordinary, unforeseen as well as foreseen, of any kind or nature
whatsoever, which are or may be assessed, levied or imposed by any Governmental
Authority (as defined in Section 22.04) upon, or become a lien or

attorneys, accountants and appraisers, in contesting any of the items set forth

Property or in achieving any tax abatement for such portion of the Property.
Except for any Fox Lance Charges which are based in whole or in part on income
(which shall be included in Taxes) and except as provided in the following
sentence with respect to changes in the method of taxation or in the taxing
authority, the term "Taxes" shall not include any income, franchise, transfer,
inheritance, capital stock, estate, profit or succession tax levied against
Landlord. If due to a future change in the method of taxation or in the taxing
authority, (x) a new or additional real estate tax or (y) a new income,
franchise, transfer, inheritance, capital stock, estate, profit or succession
tax or other tax or governmental imposition, however designated, shall be levied
against Landlord and/or the Property, in addition to or in substitution in whole

"Arcade Area" and the "Second Floor Space" located in Plaza I as more
particularly shown on Schedule D annexed hereto (collectively, the "Retained
Premises") pursuant to such agreements as may be in effect from time to time
covering the payment of such Taxes by Landlord between Landlord (or any
Affiliated Entity (as defined in paragraph (i) below)) and the owner or net
lessee of Plaza I, as the case may be (collectively, the "Retained Premises
Agreements").

               (d)  The term "Plaza I Taxes" shall mean the Taxes on Plaza I and
the land on which such building is located including all sidewalks, plazas,
streets and land adjacent to such building, and all replacements thereof, and
constituting a part of the same tax lots (i.e., tax lots B 1, A13, and S-1, and
any replacement tax lot or tax lots), excluding, however, those Taxes allocable
to the Retained Premises pursuant to the Retained Premises Agreement and which
are included in Existing Building Taxes pursuant to paragraph (c) above.

               (e)  The term "Common Area Taxes" shall mean (x) the Common Area
Tax Share (as defined in paragraph (f) below) of all Taxes allocable to the
Property plus (y) any appraisal fees incurred and paid by Landlord pursuant to
any agreements as may be in effect from time to time affecting all or part of

(collectively, "Reciprocal Agreements") or pursuant to this Lease, excluding,
however, the following items of Taxes:

          (i)  all Taxes included in Existing Building Taxes and in Plaza I
          Taxes;

                                       4
<PAGE>
 
          (ii)   all Taxes payable with respect to any portion of the Property
          that is hereafter conveyed to a third party (other than to an
          Affiliated Entity), except, however, that if any portion of the
          Property so conveyed constitutes a parking structure, and if Landlord
          both retains the right to use all or a portion of the parking spaces
          within such structure for tenants of the Complex and pays all or a
          portion of the Taxes allocable to such conveyed parking structure,
          then such Taxes so payable by Landlord with respect to such conveyed
          parking structure shall be included in Common Area Taxes;

          (iii)  all Taxes imposed or assessed (a) against any buildings or
          structures constructed on either of the two piers (the "Piers") now
          forming a part of the Property, against the portion of the Land on
          which such buildings or structures are located, and against such areas
          of the Property adjacent thereto which become unavailable for the
          general use of the tenants of the Complex during the construction of
          such buildings or structures by reason of such construction (such
          exclusion to become effective from and after the time, if any, after
          the date hereof, of "Commencement of Construction" (as hereinafter
          defined) of such buildings or structures) and (b) against any
          buildings or structures constructed on any portion of the Complex
          other than Plaza I, Plaza II, Plaza III and the Piers, against the
          portion of the Land on which such buildings or structures are located,
          and against such areas of the Property adjacent thereto which become
          unavailable for the general use of the tenants of the Complex during
          the construction of such buildings or structures by reason of such
          construction (such exclusion to become effective from and after the
          time, if any, after the date hereof, of Commencement of Construction
          of such buildings or structures), it being understood, however, that
          if any such buildings or structures shall be parking structures, all
          Taxes with respect to same and the land underlying same shall be
          included within Common Area Taxes, provided that if such buildings or
          structures are used for both parking and other uses, only the Taxes
          allocable to the portion of such structures used for parking (and an
          equitable allocation of the underlying land) shall be included in
          Common Area Taxes, such allocation to be made on the basis set forth
          in the balance of this paragraph (e).  For purposes of this Lease,
          "Commencement of Construction" shall mean the date on which, with
          respect to a certain portion of the Property, significant excavation
          commences in preparation for the installation of foundations and
          footings, and in the case of the Piers, the date on which installation
          of new pilings commences in contemplation of supporting a new building
          or structure.  At such time during or following construction of any
          such building or structure when a portion of the Land (and/or any
          buildings or structures constructed thereon), the Taxes allocable to
          which had been excluded from Common Area Taxes as of the Commencement
          of Construction, again becomes available for the general use of all
          tenants of the Complex (or to a certain tenant or tenants of the
          Complex for use as a so-called "Limited Common Area" (a Common Area
          subject to certain additional restrictions as to use imposed by
          Landlord, but which restrictions do not generally prohibit the use
          thereof by other tenants of the Complex, and which for purposes of
          this Article 3 shall nonetheless 

                                       5
<PAGE>
 
          be deemed to be "available for the general use of all tenants of the
          Complex"), the Taxes allocable to such portion of the Land (and to any
          improvements thereon similarly available for the general use of all
          tenants of the Complex) shall again be included in Common Area Taxes;
          and

          (iv)  all Taxes imposed or assessed against the common areas on the
          Piers developed in conjunction with the development of any buildings
          or structures constructed on the Piers, provided (x) such buildings or
          structures are utilized predominantly as hotel or residential space
          and the residents and employees thereof have sufficient parking
          located on the Pier on which such development was constructed (or on
          the other Pier) so that, in the aggregate, they park predominantly on
          such Pier (or on the other Pier) (such development being hereinafter
          referred to as a "Self-Contained Pier Development"), and (y) the gross
          area of such Self-Contained Pier Development shall not be included in
          the denominator of the fraction used in computing Common Area Tax
          Share.

          If any item of Taxes (or allocable portion thereof) which pursuant to
this paragraph (e) is to be included in, or excluded from, Common Area Taxes is
not wholly within a separate tax lot, then the amount of such item of Taxes (or
allocable portion thereof) to be so included in or excluded from Common Area
Taxes shall be (x) with respect to the land, in the same proportion which the
square footage of the land to be so included or excluded bears to the square
footage of the entire tax lot in which such land is located, and (y) with
respect to buildings or structures, be included or excluded, as applicable, in
the same proportion which the current appraised value of the buildings or
structures to be so included or excluded bears to the current appraised value of
all of the buildings or structures included within the tax lot of which the
footprint of land in question is a part.  If any item of Taxes (or allocable
portion thereof) which pursuant to this paragraph (e) is to be included in
Common Area Taxes because it is allocable to land which is improved with a
parking structure shall also be improved with buildings or structures used for
purposes other than parking, then the amount of such item of Taxes (or allocable
portion thereof) to be so included in Common Area Taxes shall be in the same
proportion which the current appraised value of the parking structure on such
land bears to the current appraised value of all of the buildings or structures
on such land.  All appraisals hereunder shall be determined by an appraiser
selected and paid for by Landlord, who shall be a member in good standing of the
American Institute of Real Estate Appraisers and shall have at least ten (10)
years experience appraising major office buildings in northern New Jersey and/or
in the Borough of Manhattan, City, County and State of New York.  The fees and
expenses of any such appraiser shall be deemed a part of Common Area Taxes.

               (f)  The Term "Common Area Tax Share" shall mean the share of
Common Area Taxes allocated to Plaza II, Plaza III and the Retained Premises, as
such share is determined from time to time as hereinafter set forth. The Common
Area Tax Share shall be determined as of the first day of each calendar year
(each, a "Tax Share Determination Date") and shall be equal to a fraction
(expressed as a percentage), the numerator of which shall be the aggregate gross
square footage contained in Plaza II, the Retained Premises and Plaza III, as of
the applicable Tax Share Determination Date, and the denominator of which shall
be the aggregate gross square footage contained in Plaza I, Plaza II and Plaza
III as of the applicable Tax Share Determination Date. If, at any time
hereafter, there is constructed (1) on any portion of the Land other than on the
Piers, any new buildings, or (2) on the Piers, any new building other than a
Self-Contained Pier Development, and in any of such cases, the tenants or
occupants thereof are permitted generally by Landlord to use the Common Areas
(as defined in Section 22.06 below), then the Common Area Tax Share shall be
modified to include in the denominator thereof, in addition to the aggregate
gross square footage contained in each of Plaza I, Plaza II and Plaza III as of
the applicable
                                       6
<PAGE>
 
Tax Share Determination Date, that portion of the gross square footage contained
in each such new building which either (i) on the applicable Tax Share
Determination Date is subject to a lease (other than a so-called "master lease"
to an Affiliated Entity in which event the terms hereof shall apply to any
subtenant of such master lessee) and the lessee under such lease is occupying
the Demised Premises thereunder and has begun making payments of base rent
thereunder, or (ii) at any time prior to the applicable Tax Share Determination
Date was subject to a lease described in clause (i) above, or (iii) in the case
of a residential condominium development, was sold for the first time to an
owner-occupier which is not an Affiliated Entity. Without limiting the
provisions of clause (ii) above, in no event shall the denominator of the Common
Area Tax Share ever be reduced by reason that any space which was subject to a
lease described in clause (i) above is no longer subject to such a lease. If at
any time hereafter any building located on the Land, the gross square footage of
which is then included in the denominator of the Common Area Tax Share, shall be
conveyed to a third party (other than to an Affiliated Entity), and if after
such conveyance the tenants or occupants of such building are no longer
permitted generally to use the Common Areas, then from and after the next
succeeding Tax Share Determination Date, the Common Area Tax Share shall be
modified by excluding from the denominator thereof the gross square footage
contained in such conveyed building. Landlord and Tenant agree that as of the
date of this Lease, Plaza I (exclusive of the Retained Premises) contains
385,000 gross square feet, the Retained Premises contain 23,922 gross square
feet, Plaza II contains 726,078 gross square feet and Plaza III contains 750,000
gross square feet, and based upon such amounts, the Common Area Tax Share is
79.58%. The gross square footage of any other building located on the Land shall
be determined hereinafter in the same manner as the determination of gross
square footage reflected in the immediately preceding sentence.

               (g)  The term "Tenant's Tax Share" shall mean .77% constituting
the percentage resulting from dividing the number of rentable square feet from
time to time included in the Demised Premises and with respect to which Tenant
is obligated to make Tenant's Tax Payments pursuant to Section 3.01 (b) by the
number of rentable square feet in Plaza II, Plaza III and the Retained Premises,
which the parties agree is 1,500,000 rentable square feet as of the date of this
Lease. If at any time after the date hereof rentable square footage of office,
retail or other commercial space (exclusive of storage space that is an adjunct
to such space) shall be added to or subtracted from Plaza II, the Retained
Premises and/or Plaza III, Tenant's Tax Share shall be equitably adjusted so
that Tenant pays its proportionate share of Existing Building Taxes in the same
proportion which the rentable square feet from time to time included in the
Demised Premises as set forth herein bears to the total rentable area of office,
retail or other commercial space (exclusive of such storage space) in the
improvements as to which such Existing Building Taxes relate, using the same
standard of measurement to compute the rentable area of the new or additional
space or the subtracted space as that used to compute the rentable area of the
Demised
                                       7

Premises for purposes of this Lease.  In the event of such adjustment,
Landlord and Tenant shall, at either party's request, execute an instrument
confirming such adjustment and making the appropriate change in Tenant's Tax
Share, but no such instrument shall be necessary to make the same effective.

               (h)  Tenant acknowledges that Landlord may transfer legal
ownership of portions of the Property to entities affiliated with Landlord for
purposes of obtaining tax abatements for the Property, for income tax planning
purposes or otherwise, and neither the definition of Common Area Taxes, nor of
Common Area Tax Share, nor of Existing Building Taxes nor of Tenant's Tax Share
shall be affected by reason of any such transfers to affiliated entities; all of
which shall be deemed for purposes hereof to continue to be owned by Landlord.
For purposes hereof an "Affiliated Entity" shall mean any entity which controls,
is under common control with, or is under the control of, Landlord and the term
"control" shall mean the direct or indirect ownership of 50% or more of the
outstanding voting stock in a corporation or equivalent ownership interest in a
non-corporate entity .

               (i)  If Landlord (or any Affiliated Entity) shall acquire any
additional land in the immediate vicinity of the Complex (each, an "Additional
Parcel"), then, at Landlord's election, exercisable by written notice to Tenant,
(a) the Taxes allocable to such Additional Parcel (or the portion thereof to be
used as Common Areas) shall be included in Common Area Taxes in accordance with
paragraph (e) above to the extent applicable, (b) the gross square footage of
any buildings then or thereafter constructed on such Additional Parcel, the
tenants or occupants of which are permitted generally to use the Common Areas,
shall, as of the applicable Tax Share Determination Date, be added to the
denominator of the Common Area Tax Share for purposes of calculating the Common
Area Tax Share in accordance with paragraph (f) above, using the same standard
of measurement to compute the rentable area of the new or additional buildings
as that used to compute the rentable area of the Demised Premises for purposes
of this Lease, and (c) such Additional Parcel shall thereafter be deemed a part
of the Land for all purposes of this Lease.

               (j)  In the event Tenant objects to any adjustment which may be
required under this Section 3.01 (a) with respect to Existing Building Taxes,
Common Area Taxes, Common Area Tax Share or Tenant's Tax Share, such objection
must be made in writing by Tenant within thirty (30) days after receipt of
Landlord's determination of such adjustment, specifying in detail the nature of
such objection, and failing such notice Landlord's determination shall be
conclusive.  If Tenant does so object, either party may submit such dispute to
arbitration in accordance with the provisions of Article 43, but pending the
resolution of such dispute, Landlord's determination of Existing Building Taxes,
Common Area Taxes, Common Area Tax Share and Tenant's Tax Share shall control
and Tenant shall pay Tenant's Tax Payment (as defined in Section 3.01 (B)) in
accordance with such determination as a condition precedent to its right to
invoke the arbitration process herein provided without prejudice to Tenant's
position.  In the event of the resolution of such dispute so that there shall
have been an overpayment of Tenant's Tax Payment, Landlord shall permit Tenant
to credit the amount of such overpayment against the next subsequent rental
payments under this Lease.  After the termination of this Lease and the payment
to Landlord of the balance, if any, of all Basic Annual Rent and additional rent
due hereunder, Landlord shall pay to Tenant the amount of any credit not
previously applied by 

                                       8
<PAGE>
 
Tenant. In the event any such dispute shall involve more than one Tenant of the
Property, all of such disputes shall, at Landlord's election, be resolved in one
arbitration proceeding designated by Landlord.

               (k)  The term "Escalation Statement" shall mean a statement
setting forth the amount payable by Tenant for a specified Tax Year or Operating
Year (as defined in Section 3.02), as the case may be, or for some portion
thereof pursuant to this Article 3.

          B.   Tenant shall pay to Landlord as additional rent for each Tax Year
or partial Tax Year commencing from and after January 1, 1997, an amount equal
to Tenant's Tax Share of the excess of the Existing Building Taxes for such Tax
Year over the Existing Building Taxes for the Base Tax Year and Tenant's Tax
Share of the excess of the Common Area Taxes for such Tax Year over the Common
Area Taxes for the Base Tax Year (collectively, "Tenant's Tax Payment").
Landlord shall furnish Tenant an annual Escalation Statement (subject to
revision as hereinafter provided) for each Tax Year setting forth Tenant's Tax
Payment (or, if Landlord has not yet received bills evidencing the full amount
of Taxes payable during such Tax Year, Landlord's good faith estimate of
Tenant's Tax Payment, which shall for all purposes hereof be deemed to be the
Taxes for such Tax Year payable hereunder until such Taxes are finally
determined) for such Tax Year. Tenant's Tax Payment (determined as above
provided) shall be payable in the same number of installments as Landlord pays
(or is deemed to have paid, as hereinafter set forth) Taxes, each such
installment to be in such amount and due at such time (but not more frequently
than monthly) such that Landlord shall have received Tenant's Tax Share of (i)
all installments of Existing Building Taxes and (ii) all installments of Common
Area Taxes payable, in either case, to a Governmental Authority, or to any
designated party under any applicable Reciprocal Agreements (a "Responsible
Party"), or as tax escrow payments to any superior ground lessor or mortgagee,
not less than thirty (30) days prior to the date such installment of Existing
Building Taxes or Common Area Taxes is payable to such Governmental Authority,
Responsible Party or superior ground lessor or mortgagee, as applicable. If an
annual Escalation Statement is furnished to Tenant after the commencement of the
Tax Year to which it relates, then (i) until such Escalation Statement is
rendered, Tenant shall pay Tenant's Tax Payment for such Tax Year in
installments based upon the last Escalation Statement rendered to Tenant with
respect to Existing Building Taxes and Common Area Taxes, (ii) Tenant shall,
within ten (10) days after such annual Escalation Statement is furnished to
Tenant, pay to Landlord an amount equal to any underpayment of the installments
of Tenant's Tax Payment theretofore paid by Tenant for such Tax Year and (iii)
thereafter Tenant shall pay Tenant's Tax Payment in installments based on such
annual Escalation Statement. In the event of an overpayment by Tenant, Landlord
shall permit Tenant to credit the amount of such overpayment against the next
subsequent rental payments under this Lease. After the termination of this Lease
and the payment to Landlord of the balance, if any, of all Basic Annual Rent and
additional rent due hereunder, Landlord shall pay to Tenant the amount of any
credit not previously applied by Tenant. If there shall be any increase or
decrease in Existing Building Taxes or Common Area Taxes for any Tax Year,
whether during or after such Tax Year, Landlord shall furnish a revised
Escalation Statement for such Tax Year to Tenant, and Tenant's Tax Payment for
such Tax Year shall be adjusted and paid or credited, as appropriate, in the
same manner as hereinabove provided.

                                       9
<PAGE>
 
                C.  If Landlord shall receive a refund of Existing Building
Taxes or Common Area Taxes for any Tax Year, Landlord shall promptly notify
Tenant and shall permit Tenant to credit against subsequent rental payments
under this Lease, Tenant's Tax Share of the refund, but not in excess of
Tenant's Tax Payment paid for such Tax Year. After the termination of this Lease
and the payment to Landlord of the balance, if any, of all Basic Annual Rent and
additional rent due hereunder, Landlord shall pay Tenant the amount of any
credit not previously applied by Tenant.

          3.02. A.  For purposes hereof the following definitions shall apply:

                (a)  The term "Operating Year" shall mean each calendar year
which includes any part of the period commencing on January 1, 1997 and ending
upon the expiration of the Term. The term "Base Operating Year" shall mean the
calendar year commencing January 1, 1997.

                (b)  The term "Tenant's Expense Share" shall mean .81%
constituting the percentage resulting from dividing the number of rentable
square feet from time to time included in the Demised Premises and with respect
to which Tenant is obligated to make Tenant's Expense Payments pursuant to
Section 3.02(b) by the number of rentable square feet in the Retained Premises,
Plaza II, Plaza III and the Retained Premises, exclusive of space leased to
retail tenants, which the parties agree is 1,430,000 rentable square feet as of
the date of this Lease. If at any time after the date hereof additional rentable
square footage of office space (exclusive of storage space that is an adjunct to
such space) shall be added to or subtracted from the Retained Premises, Plaza II
and/or Plaza III, Tenant's Expense Share shall be equitably adjusted so that
Tenant pays its proportionate share of Operating Expenses in the same proportion
which the rentable square feet from time to time included in the Demised
Premises as set forth herein bears to the total rentable area of office space
(exclusive of such storage space) in the improvements as to which such Operating
Expenses relate, using the same standard of measurement to compute the rentable
area of the new or additional space or subtracted space as that used to compute
the rentable area of the Demised Premises for purposes of this Lease. In the
event of such adjustment, Landlord and Tenant shall, at either party's request,
execute an instrument confirming such adjustment and making the appropriate
change in Tenant's Expense Share, but no such instrument shall be necessary to
make the same effective.

                (c)  The term "Common Area Expense Share" shall mean the share
of Common Area Operating Expenses allocated to Plaza II, Plaza III and the
Retained Premises, as such share is determined from time to time as hereinafter
set forth. The Common Area Expense Share shall be determined as of the first day
of each calendar year (each, an "Expense Share Determination Date") and shall be
equal to a fraction (expressed as a percentage), the numerator of which shall be
the aggregate gross square footage contained in Plaza II, the Retained Premises
and Plaza III, as of the applicable Expense Share Determination Date, and the
denominator of which shall be the aggregate gross square footage contained in
Plaza I, Plaza II and Plaza III as of the applicable Expense Share Determination
Date (the "Expense Share Fraction"). If, at any time hereafter, there is
constructed (1) on any portion of the Land other than on the Piers any new
buildings, or (2) on the Piers, any new building other than a Self-Contained
Pier Development, and in any of such cases, the tenants or occupants thereof are
permitted by Landlord generally to 

                                      10
<PAGE>
 
use the Common Areas, then the Expense Share Fraction shall be modified to
include in the denominator thereof, in addition to the aggregate of the gross
square footage contained in each of Plaza I, Plaza II and Plaza III as of the
applicable Expense Share Determination Date, the gross square footage contained
in that portion of each such new building which either (i) on the applicable
Expense Share Determination Date is subject to a lease (other than a so-called
"master lease" to an Affiliated Entity in which event the terms hereof shall
apply to any subtenant of such master lessee) and the lessee under such lease is
either occupying the Demised Premises thereunder, or has begun making payments
of base rent thereunder or (ii) at any time prior to the applicable Expense
Share Determination Date was subject to a lease described in clause (i) above,
or (iii) in the case of a residential condominium development, was sold for the
first time to an owner-occupier which is not an Affiliated Entity. Without
limiting the provisions of clause (ii) above, in no event shall the denominator
of the Expense Share Fraction ever be reduced by reason that any space which was
subject to a lease described in clause (i) above is no longer subject to such a
lease. If at any time hereafter any building located on the Land, the gross
square footage of which is then included in the denominator of the Expense Share
Fraction, shall be conveyed to a third party (other than to an Affiliated
Entity), and if after such conveyance the tenants or occupants of such building
are no longer permitted generally to use the Common Areas, then from and after
the next succeeding Expense Share Determination Date, the Expense Share Fraction
shall be modified by excluding from the denominator thereof the gross square
footage contained in such conveyed building. Landlord and Tenant agree that as
of the date of this Lease Plaza I (exclusive of the Retained Premises) contains
385,000 gross square feet, the Retained Premises contains 23,922 gross square
feet, Plaza II contains 726,078 gross square feet and Plaza III contains 750,000
gross square feet, and based upon such amounts, the Common Area Expense Share is
79.58%. The gross square footage of any other building located on the Land shall
be determined hereinafter in the same manner as the determination of gross
square footage reflected in the immediately preceding sentence.

               (d)  The term "Common Area Operating Expenses" shall mean the
Common Area Expense Share of the total of all unreimbursed (other than pursuant
to this Article 3) costs and expenses (including taxes thereon, if any),
computed on an accrual basis, incurred by Landlord in connection with operating,
maintaining, repairing and replacing the Common Areas (as defined in Section
22.05), including, without limitation, the cost and expense of the following
items to the extent they relate solely to or are reasonably allocable to the
Common Areas (Tenant hereby acknowledging that it is not possible to make such
allocation with mathematical certainty and that any such good faith allocation
made by Landlord shall be binding upon Tenant): gardening, landscaping,
planting, replanting, and replacing flowers and shrubbery; public liability,
property damage and fire insurance with such extended coverage and vandalism
endorsements required by the holder of any mortgage covering all or any portion
of the Common Areas or customarily carried with respect to mixed use office and
retail projects similar to the Complex in northern New Jersey; repairs; painting
and decorating; striping; the cost of electricity for lighting and maintenance
and replacements of lighting fixtures, tubes and bulbs; regulating automobile
and pedestrian traffic; sanitary control; removal of rubbish, garbage and other
refuse; removal of snow and ice, and sanding and salting; security, which shall
include special security undertakings for the common use and enjoyment of all
tenants and owners of all or a portion of the Complex; actions to prevent
unauthorized use of certain of the Common Areas; supplies used 

                                      11
<PAGE>
 
in the operation and maintenance of the Common Areas (including the cost of
inspection thereof); drainage; music program services and loud speaker systems,
including electricity therefor; heating, ventilating and air-conditioning
enclosed sidewalks, if any; cleaning all enclosed sidewalks, if any, including
carpeting or other floor covering; maintenance of decorations, if any; cost of
personnel to implement all of the aforementioned (including worker's
compensation insurance covering such personnel); all administrative and overhead
costs, excluding executive salaries above the grade of building manager; all
water and sewer charges; outside contractor snow removal costs; and any other
fees and expenses related solely to or which are reasonably allocable to the
operation, maintenance and repair of the Common Areas; provided, however, that
the foregoing costs and expenses shall exclude or have deducted from them, or
shall include in the specific circumstances hereinafter provided, as the case
may be, the following:

          (i)    Taxes;

          (ii)   interest, principal and refinancing and other charges on or
          with respect to indebtedness;

          (iii)  amounts received by Landlord through proceeds of insurance to
          the extent they are compensation for sums previously included in
          Common Area Operating Expenses hereunder;

          (iv)   costs of repairs incurred by reason of fire or other casualty
          or condemnation to the extent Landlord is compensated therefor by
          insurance proceeds or condemnation award;

          (v)    advertising and promotional expenses;

          (vi)   leasing commissions and similar fees;

          (vii)  rent under any ground lease;

          (viii) depreciation, except that if any equipment is purchased for
          maintenance and operation of the Common Areas which is not ordinarily
          expensed, then such equipment shall be depreciated on a straight-line
          basis over the lesser of (i) the useful life of such equipment or (ii)
          ten (10) years, and there shall be included in Common Area Operating
          Expenses in each Operating Year the amount of such depreciation
          attributable to such Operating Year, provided, however, that all
          amounts thereof included in Common Area Operating Expenses in
          Operating Years subsequent to the year paid shall have added thereto
          interest at the Prime Rate (as defined in Section 22.03) (determined
          as of the date on which such expense was incurred) plus one percent
          (1%) from the date each such expense was incurred by Landlord;

          (ix)   as to salaries and other compensation and professional fees of
          persons employed or retained at or for the Common Areas and at
          additional locations other than the Common Areas, only a pro rata
          allocation (based on an equitable time 

                                      12
<PAGE>
 
          allocation) of the foregoing expenses incurred on behalf of the Common
          Areas shall be included in Common Area Operating Expenses;

          (x)    costs and expenses payable to any Affiliated Entity or its
          partners or stockholders to the extent that such costs and expenses
          exceed, in any material respect, competitive costs and expenses
          generally charged for materials or services rendered by persons or
          entities (other than any Affiliated Entity or its partners or
          stockholders) of similar skill, competence and experience;

          (xi)   all costs and expenses included in Operating Expenses;

          (xii)  all costs and expenses allocable to any portion of the Common
          Areas that is hereafter conveyed to a third party (other than to an
          Affiliated Entity), except, however, that if any portion of the Common
          Areas so conveyed constitutes a parking structure, and if Landlord
          both retains the right to use all or a portion of the parking spaces
          within such structure for tenants of the Complex and pays all or a
          portion of the costs and expenses allocable to such conveyed parking
          structure then such costs and expenses payable by Landlord with
          respect to such conveyed parking structure shall be included in Common
          Area Operating Expenses;

          (xiii) all costs and expenses allocable to (a) any buildings or
          structures constructed on either of the Piers, or allocable to any
          portions of the Common Areas adjacent thereto which become unavailable
          for the general use of the tenants of the Complex during the
          construction of such buildings or structures by reason of such
          construction (such exclusion to become effective from and after the
          time, if any, of Commencement of Construction (of such buildings or
          structures) and (b) any buildings or structures constructed on any
          portion of the Complex other than Plaza I, Plaza II, Plaza III and the
          Piers, or allocable to any portions of the Common Areas adjacent
          thereto which become unavailable for the general use of the tenants of
          the Complex during the construction of such buildings or structures by
          reason of such construction (such exclusion to become effective from
          and after the time, if any, after the date hereof, of Commencement of
          Construction of such buildings or structures).  During construction of
          any such building or structure, as and when any portion of the land
          (and any improvements constructed thereon), the costs and expenses
          allocable to which had been excluded from Common Area Operating
          Expenses as of the Commencement of Construction, again becomes
          available for the general use of all tenants of the Complex, the costs
          and expenses allocable to such land (and to any improvements thereon
          similarly available for the general use of all tenants of the Complex
          including, without limitation, parking structures) shall again be
          included in Common Area Operating Expenses; and

          (xiv)  all costs and expenses allocable to the common areas of a Self-
          Contained Pier Development.

                                      13
<PAGE>
 
          If any of the costs and expenses which, pursuant to the terms of this
paragraph (d) are to be included in or excluded from Common Area Operating
Expenses depending upon the portion of the Property to which they relate, are
incurred with respect to both such included and excluded portions of the
Property, then Landlord shall make a good faith estimate of the amount of such
cost or expense allocable to such included or excluded portion of the Property,
and only the pro rata allocation (based on Landlord's estimate) of such cost or
expense incurred on behalf of the included portion of the Property shall be
included in Common Area Operating Expenses.  Such allocation shall be binding on
Landlord and Tenant unless Tenant shall dispute same in accordance with Section
3.07 within thirty (30) days after Landlord gives Tenant notice of such
allocation.  Tenant shall only be able to challenge such allocation if Tenant
can establish in arbitration in accordance with the provisions of this Lease
that such allocation was arbitrary and made in bad faith, giving due
consideration to the fact that it is not possible to make such allocation with
mathematical certainty.  Pending such arbitration, Landlord's allocation shall
control and Tenant shall make Tenant's Expense Payments based thereon.

               (e)  The term "Operating Expenses" shall mean, subject to the
provisions of paragraphs (f) and (g) below, the total of all costs and expenses
(including taxes thereon, if any), computed on an accrual basis, incurred by
Landlord in connection with operating, repairing and maintaining Plaza II, Plaza
III and the Retained Premises (the "Existing Buildings") in a manner customary
for mixed use office/retail complexes in northern New Jersey similar to the
Complex including, without limitation, the costs and expenses with respect to:
steam, gas and any other fuel or utilities; water rates (including without
limitation, for public drinking facilities and bathrooms), water charges and
sewer rents; operation of the heating, ventilation and cooling systems;
electricity and other utilities for areas other than those leased or available
for lease to individual tenants as indicated by meter, or if there be no meter,
as determined by Landlord's electrical consultant (as defined in Section 4.08);
elevators and escalators; metal, elevator cab, lobby, interior mall and other
interior public area maintenance and cleaning; painting and decoration of non
tenant areas; window cleaning; sanitary control; security; maintenance and
replacement of lighting fixtures, tubes and bulbs in non tenant areas; music
program services and loud speaker system; depreciation of hand tools and other
movable equipment used in the operation or maintenance of the Existing
Buildings; maintenance of conduits in the Existing Buildings as necessary for
shared tenant systems; flood, fire, extended coverage, boiler and machinery,
sprinkler apparatus, public liability and property damage, loss of rental,
fidelity and plate glass insurance and any other insurance required by the
holder of any mortgage or ground lease covering all or any portion of the
Existing Buildings or customarily carried with respect to mixed use
office/retail complexes in northern New Jersey similar to the Property; wages,
salaries, bonuses, disability benefits, hospitalization, medical, surgical,
dental, optical, psychiatric, legal, union and general welfare benefits
(including group life insurance), any pension, retirement or life insurance plan
and other benefit or similar expense respecting employees of Landlord (or its
agents) up to and including the building manager, provided that to the extent
that Landlord employs the services of any such persons at the Existing Buildings
and at additional locations other than the Existing Buildings, then only a pro
rata allocation (based on an equitable time allocation) of the foregoing
expenses incurred on behalf of the Existing Buildings shall be included in
Operating Expenses; uniforms and working clothes for such employees and the
cleaning and replacement thereof; expenses imposed on Landlord pursuant to law
or to any 

                                      14
<PAGE>
 
collective bargaining agreement with respect to such employees; workmen's
compensation insurance, payroll, social security, unemployment and other similar
taxes with respect to such employees; salaries of bookkeepers and accountants,
provided that to the extent that Landlord employs the services of any such
persons at the Existing Buildings and at additional locations other than the
Existing Buildings, then only a pro rata allocation (based on an equitable time
allocation) of the foregoing expenses incurred on behalf of the Existing
Buildings shall be included in Operating Expenses; professional and consulting
fees, including legal and accounting fees; charges for independent contractors
performing work included within the definition of Operating Expenses;
association fees or dues; telephone and stationery; directory; building
telephone; repairs, replacements and improvements of the electrical, mechanical,
plumbing and HVAC systems and other systems and portions of the Existing
Buildings, which are necessary or appropriate for the continued operation of the
Existing Buildings in a manner customary for mixed use office/retail complexes
in northern New Jersey similar to the Complex or are otherwise imposed upon
Landlord by any Governmental Authority; and management fees for the management
of the Existing Buildings, or if no managing agent is employed by Landlord, a
sum in lieu thereof which is not in excess of the then prevailing rates for
management fees in northern New Jersey for mixed use office/retail complexes
similar to the Property. There shall also be included in Operating Expenses (but
only to the extent the same are not otherwise included therein) any items
described in the definition of Common Area Operating Expenses which are
performed to the exterior of Plaza II and Plaza III, but which, by reason of
their relating to areas adjacent to Plaza II and Plaza III, are not included in
Common Area Operating Expenses and are performed and paid for directly by the
owner of Plaza II and Plaza III. If any of the costs and expenses includible in
Operating Expenses are incurred by Landlord with respect to both the Existing
Buildings and other portions of the Property, then Landlord shall make a good
faith estimate of the amount of such cost or expense allocable to the Existing
Buildings and the amount thereof allocable to such other portions of the
Property, and only the pro rata allocation (based on Landlord's estimate) of
such cost or expense incurred on behalf of the Existing Buildings shall be
included in Operating Expenses. Such allocation shall be binding on Landlord and
Tenant unless Tenant shall dispute same in accordance with Section 3.07 within
thirty (30) days after Landlord gives Tenant notice of such allocation. Tenant
shall only be able to challenge such allocation if Tenant can establish in
arbitration in accordance with the provisions of this Lease that such allocation
was arbitrary and made in bad faith, giving due consideration to the fact `that
it is not possible to make such allocation with mathematical certainty. Pending
such arbitration, Landlord's allocation shall control and Tenant shall make
Tenant's Expense Payments based thereon. It is understood and agreed that
Landlord shall not be permitted to include the same item of expense in both
Operating Expenses and Common Area Expenses except to the extent such item of
expense is allocated between them as expressly contemplated hereby.

               (f)  If any repair, replacement or improvement within the
definition of Operating Expenses must be capitalized under generally accepted
accounting principles as determined by the accountants who prepare the accounts
with respect to the Existing Buildings, then, unless same is necessary to comply
with a Legal Requirement (in which case the same shall be included within
Operating Expenses in the year incurred) or except as otherwise provided in
paragraph (g) below, the cost thereof shall be amortized on a straight line
basis over the lesser of (i) the useful life of such repair, replacement or
improvement or (ii) a period of ten (10) years,

                                      15
<PAGE>
 
and there shall be included in Operating Expenses in each Operating Year for
such portion of the amortization period which occurs during the Term, the amount
so amortized attributable to such Operating Year, provided, however, that all
amounts thereof included in Operating Expenses in Operating Years subsequent to
the year paid shall have added thereto interest at the Prime Rate plus one
percent (1%) from the date Landlord incurred such cost.

                   (g)  The following shall be excluded or deducted from, or, in
the specific circumstances hereinafter provided, included in, as appropriate,
the costs and expenses otherwise included in Operating Expenses:

          (i)    the cost of electricity and other utilities furnished to the
          Demised Premises and other space leased or available for lease to
          tenants as measured by meters, or if there be no meters, as determined
          by Landlord's electrical consultant (as defined in Section 4.08);

          (ii)   leasing commissions and similar fees;

          (iii)  salaries, fringe benefits and other compensation for Landlord's
          executives above the grade of building manager;

          (iv)   amounts received by Landlord through proceeds of insurance to
          the extent the proceeds are compensation for expenses which were
          previously included in Operating Expenses;

          (v)    cost of repairs or replacements incurred by reason of fire or
          other casualty or condemnation to the extent Landlord is compensated
          therefor by insurance proceeds or a condemnation award;

          (vi)   advertising and promotional expenditures;

          (vii)  Taxes;

          (viii) costs for performing tenant installations for any individual
          tenant or for performing work or furnishing services to or for
          individual tenants at such tenant's expense and any other contribution
          by Landlord to the cost of tenant improvements;

          (ix)   capital expenditures incurred for the initial renovation of the
          improvements constituting the Existing Buildings (e.g., the erection
          of a new facade, new windows and a new elevator core);

          (x)    rent under any ground leases;

          (xi)   financing and refinancing costs and mortgage debt service;

                                      16
<PAGE>
 
          (xii)   costs of furnishing services to other tenants or occupants to
          the extent such services are materially in excess of services Landlord
          offers to all tenants at Landlord's expense;

          (xiii)  amounts otherwise includible in Operating Expenses but
          reimbursed directly by Tenant or other tenants to Landlord other than
          by escalation provisions similar to this Article 3;

          (xiv)   costs and expenses payable to any Affiliated Entity, to the
          extent that such costs and expenses exceed in any material respect
          competitive costs and expenses for materials and services by unrelated
          persons or entities (other than and Affiliated Entity or its partners
          or stockholders) of similar skill, competence and experience;

          (xv)    franchise, income, inheritance or estate taxes (but not sales
          and use taxes) imposed on Landlord;

          (xvi)   all amounts included in Common Area Operating Expenses; and

          (xvii)  depreciation, except that if any equipment is purchased for
          maintenance and operation of the Existing Buildings which is not
          ordinarily expensed, then such equipment shall be depreciated on a
          straight-line basis over the lesser of (i) the useful life of such
          equipment or (ii) ten (10) years, and there shall be included in
          Operating Expenses in each Operating Year the amount of such
          depreciation attributable to such Operating Year, provided, however,
          that all amounts thereof included in Operating Expenses in Operating
          Years subsequent to the year paid shall have added thereto interest at
          the Prime Rate (as defined in Section 22.03) (determined as of the
          date on which such expense was incurred) plus one percent (1 %) from
          the date each such expense was incurred by Landlord.

                  (h)  If during all or part of any Operating Year, Landlord
shall not furnish any particular item(s) of work or service (which would
constitute an Operating Expense) to portions of the Existing Buildings, due to
the fact such portions are not occupied or leased, or because such item of work
or service is not required or desired by the tenant of such portion, or such
tenant is itself obtaining and providing such item of work or service, then, for
the purpose of computing the additional rent payable hereunder, the amount of
Operating Expenses for such item for such period shall be increased by an amount
equal to the actual incremental cost which would reasonably have been incurred
during such period by Landlord if it had at its own expense furnished such item
of work or services to such portion of the Existing Buildings.

                  (i)  Tenant acknowledges that Landlord may transfer legal
ownership of portions of the Property to an Affiliated Entity for purposes of
obtaining tax abatements for the Property, for tax planning purposes or
otherwise, and neither the definition of Operating Expenses nor of Tenant's
Expense Share nor of Common Area Expenses, nor of Common Area Expense Share
shall be affected by reason of any such transfers to Affiliated Entities; all of
which shall be deemed for purposes hereof to continue to be owned by Landlord.

                                      17
<PAGE>
 
               (j)  If Landlord (or any Affiliated Entity) shall acquire an
Additional Parcel, then, at Landlord's election, exercisable by written notice
to Tenant (a) the Common Area Operating Expenses allocable to such Additional
Parcel (or the portion thereof to be used as Common Areas) shall be included in
Common Area Operating Expenses in accordance with paragraph (d) above to the
extent applicable, (b) the gross square footage of any improvements then or
thereafter constructed on such Additional Parcel, the tenants or occupants of
which are permitted generally to use the Common Areas, shall, as of the
applicable Expense Share Determination Date, be added to the denominator of the
Expense Share Fraction for purposes of calculating the Common Area Expense Share
in accordance with paragraph (c) above, and (c) such Additional Parcel shall
thereafter be deemed a part of the Land for all purposes of this Lease.

               (k)  In the event Tenant objects to any adjustment which may be
required under this Section 3.02(a) with respect to Operating Expenses, Common
Area Operating Expenses, Tenant's Expense Share or Common Area Expense Share,
such objection must be made in writing by Tenant within thirty (30) days after
receipt of Landlord's determination of such adjustment, specifying in detail the
nature of such objection, and failing such notice Landlord's determination shall
be conclusive.  If Tenant does so object, either party may submit such dispute
to arbitration in accordance with the provisions of Article 43, but pending the
resolution of such dispute, Landlord's determination of Operating Expenses,
Common Area Operating Expenses, Tenant's Expense Share and Common Area Expense
Share shall control and Tenant shall pay Tenant's Expense Payment (as defined in
Section 3.02(b) below) in accordance with such determination as a condition
precedent to its right to invoke such arbitration process without prejudice to
Tenant's position.  In the event of the resolution of such dispute so that there
shall have been an overpayment of any of Tenant's Expense Payment, Landlord
shall permit Tenant to credit the amount of such overpayment against the next
subsequent rental payments under this Lease.  After the termination of this
Lease and the payment to Landlord of the balance, if any, of all Basic Annual
Rent and additional rent due hereunder, Landlord shall pay Tenant the amount of
any credit not previously applied by Tenant.  In the event any such dispute
shall involve more than one tenant of the Property, all of such disputes shall,
at Landlord's election, be resolved in one arbitration proceeding designated by
Landlord.

               B.   Tenant shall pay to Landlord as additional rent for each
Operating Year an amount equal to Tenant's Expense Share of the excess of the
Operating Expenses for such Operating Year over the Operating Expenses for the
Base Operating Year and Tenant's Expense Share of the excess of the Common Area
Operating Expenses for such Operating Year over the Common Area Operating
Expenses for the Base Operating Year (collectively, "Tenant's Expense Payment").

               C.   Landlord shall furnish to Tenant for each Operating Year an
Escalation Statement (subject to revision as hereinafter provided) setting forth
Landlord's estimate of Tenant's Expense Payment for such Operating Year.  Tenant
shall pay to Landlord on the first day of each month during such Operating Year
an amount equal to one-twelfth (1/12) of Landlord's estimate of Tenant's Expense
Payment for such Operating Year.  If Landlord shall furnish such estimate for an
Operating Year after the commencement thereof, then (i) until the first day of
the month following the month in which such estimate is furnished to Tenant,
Tenant 

                                      18
<PAGE>
 
shall pay to Landlord on the first day of each month an amount equal to the
monthly sum payable by Tenant to Landlord under this paragraph (c) for the last
month of the preceding Operating Year; (ii) on the first day of the month
following the month in which such estimate is furnished to Tenant and monthly
thereafter for the balance of such Operating Year, Tenant shall pay to Landlord
an amount equal to one-twelfth (1/12) of Tenant's Expense Payment as shown on
such estimate; and (iii) Landlord shall notify Tenant in the Escalation
Statement containing such estimate whether the installments of Tenant's Expense
Payment previously paid for such Operating Year were more or less than the
installments which should have been paid for such Operating Year pursuant to
such estimate. If there shall be an underpayment, Tenant shall pay the amount
thereof within ten (10) days after being furnished with such Escalation
Statement or (ii) if there shall be an overpayment, Tenant shall be entitled to
a credit in the amount thereof against the next subsequent rental payments under
this Lease. After the termination of this Lease and the payment to Landlord of
the balance, if any, of all Basic Annual Rent and additional rent due hereunder,
Landlord shall pay Tenant the amount of any credit not previously applied by
Tenant. Landlord may at any time and from time to time (but not more often than
three times in any Operating Year) furnish to Tenant an Escalation Statement
setting forth Landlord's revised estimate of Tenant's Expense Payment for a
particular Operating Year and Tenant's Expense Payment for such Operating Year
shall be adjusted and paid or credited, as applicable, in the same manner as
provided in the preceding sentence.

               D.  After the end of each Operating Year Landlord shall submit to
Tenant an annual Escalation Statement prepared by Landlord or its agent setting
forth the Operating Expenses and Common Area Operating Expenses for the
preceding Operating Year and the balance of Tenant's Expense Payment, if any,
due to Landlord from Tenant for such Operating Year.  If such annual Escalation
Statement shall show that the sums paid by Tenant under Section 3.02(c) exceeded
Tenant's Expense Payment for such Operating Year, Tenant shall be entitled to a
credit in the amount of such excess against the next subsequent rental payments
under this Lease.  After the termination of the Lease and the payment to
Landlord of the balance, if any, of all Basic Annual Rent and additional rent
due hereunder, Landlord shall pay Tenant the amount of any credit not previously
applied by Tenant.  If an annual Escalation Statement shall show that the sums
so paid by Tenant were less than Tenant's Expense Payment for such Operating
Year, Tenant shall pay the amount of such deficiency to Landlord within ten (10)
days after being furnished with such annual Escalation Statement.

               E.  The annual Escalation Statements with respect to Operating
Expenses and Common Area Operating Expenses to be furnished by Landlord or its
agent as provided above may be unaudited but shall be in reasonable detail.
Landlord and its agent may rely on Landlord's operating cost allocations and
estimates if such allocations or estimates are required for this Section 3.02.

               F.  Upon Tenant's written request, Landlord shall permit Tenant
or its representatives to inspect the books and records relating to the
operation of the Property for the Operating Year to which an Escalation
Statement relates at the office of Landlord's managing agent at such time or
times during normal business hours as Landlord shall reasonably designate.
Tenant shall have the right to obtain copies or make such abstracts thereof as
it may reasonably require in order to verify any Escalation Statement. If, based
upon Tenant's inspection, it is 

                                      19
<PAGE>
 
determined (either by agreement of the parties or by a final unappealable
arbitration award) that Landlord's annual Escalation Statement for Operating
Expenses for a particular Operating Year was overstated by more than 5%, then
Landlord will reimburse Tenant for the reasonable costs it incurred to outside,
independent auditors to conduct such inspection within ten (10) days after
demand based upon reasonable substantiation by Tenant of such costs.

          3.03.  Tenant shall pay to the appropriate Governmental Authority on
or before the due date thereof all taxes, assessments and other charges which
are or may be assessed, levied or imposed by any Governmental Authority upon, or
become a lien or due and payable in respect of, any leasehold interest of
Tenant, any investment of Tenant in the Demised Premises, any right of Tenant to
occupy the Demised Premises or any personal property of any kind owned,
installed or used by Tenant at or in connection with the operation of the
Demised Premises or in connection with Tenant's business conducted at the
Demised Premises and, at Landlord's request, furnish Landlord with reasonable
evidence, within ten (10) days after demand, that the same have been paid.

          3.04.  If the Commencement Date shall be other than the first day of a
Tax Year or an Operating Year or if the Expiration Date shall be a day other
than the last day of a Tax Year or an Operating Year, then Tenant's Tax Payment
and/or Tenant's Expense Payment for such partial year shall be equitably
adjusted taking into consideration the portion of such Tax Year or Operating
Year falling within the Term. Landlord shall, as soon as reasonably practicable,
cause an Escalation Statement with respect to Existing Building Taxes and Common
Area Taxes for the Tax Year and/or Operating Expenses and Common Area Operating
Expenses for the Operating Year in which the Term expires to be prepared and
furnished to Tenant. Such Escalation Statement shall be prepared as of the
Expiration Date of the Term if such date is December 31, and if not, as of the
first to occur of June 30 or December 31 after the Expiration Date of the Term.
Landlord and Tenant shall thereupon make appropriate adjustments of amounts then
owing.

          3.05.  In no event shall the Basic Annual Rent ever be reduced by
operation of this Article 3. The rights and obligations of Landlord and Tenant
under the provisions of this Article 3 shall survive the termination of this
Lease, and payments shall be made pursuant to this Article 3 notwithstanding the
fact that an Escalation Statement is furnished to Tenant after the expiration or
other termination of the Term.

          3.06.  Landlord's failure to render an Escalation Statement with
respect to any Tax Year or Operating Year shall not prejudice Landlord's right
to thereafter render an Escalation Statement with respect thereto or with
respect to any subsequent Tax Year or Operating Year.

          3.07.  Each Escalation Statement shall be conclusive and binding upon
Tenant unless within thirty (30) days after receipt of such Escalation Statement
Tenant shall notify Landlord that it disputes the correctness of such Escalation
Statement, specifying the particular respects in which such Escalation Statement
is claimed to be incorrect. Any such dispute may be submitted to arbitration in
accordance with Article 43 by either party, but pending the resolution of such
dispute, and as a condition precedent to Tenant's right to invoke such
arbitration process, Tenant shall make its payments in accordance with such
Escalation Statement without prejudice 

                                      20
<PAGE>
 
to Tenant's position. In the event of the resolution of such dispute so that
there shall have been an overpayment of any of Tenant's Tax Payment and/or
Tenant's Expense Payment, Landlord shall permit Tenant to credit the amount of
such overpayment against the next subsequent rental payments under this Lease.
After the termination of this Lease and the payment to Landlord of the balance,
if any, of all Basic Annual Rent and additional rent due hereunder, Landlord
shall pay to Tenant the amount of any credit not previously applied by Tenant.
Tenant agrees, at Landlord's request, to be a party to any arbitration between
Landlord and any other tenant of the Property concerning the interpretation of
any provision similar to a provision in this Article 3 in such other tenant's
lease. Tenant shall not be responsible for the cost of any such arbitration,
except that Tenant shall bear the cost of its own counsel, experts and
presentation of proof, if any.

          3.08.  Tenant will cooperate with Landlord in all reasonable respects
in obtaining and retaining any tax abatement or exemption for which the Property
may be eligible. Tenant will execute and file within ten (10) days after demand
any and all documents and instruments reasonably necessary to obtain and retain
such abatement or exemption.

                                   ARTICLE 4

                                  ELECTRICITY

          4.01.  Landlord agrees that prior to the Commencement Date risers,
feeders and wiring will be installed in the Building by Landlord to furnish
electrical service to the Demised Premises in accordance with work required
pursuant to No. 1 of Schedule C. After the Commencement Date any additional
risers, feeders or other equipment or service proper or necessary to supply
Tenant's electrical requirements, upon written request of Tenant, will be
installed by Landlord at the sole cost and expense of Tenant, if in Landlord's
sole judgment the same are available and necessary for Tenant's use and will not
cause permanent damage or injury to the Property or the Demised Premises or
cause or create a dangerous or hazardous condition or entail excessive or
unreasonable alterations, repairs or expense or interfere with or disturb other
tenants or occupants.

          4.02.  Tenant covenants and agrees to pay directly to the utility
company supplying electricity to the Demised Premises the amounts due for
electric current consumed by Tenant as indicated by meters measuring Tenant's
consumption thereof.

          4.03.  Tenant's use of electric current in the Demised Premises shall
not at any time exceed the capacity of any of the electrical conductors and
equipment in or otherwise serving the Demised Premises. The electrical
conductor's and equipment for the Fourth Floor Space have a capacity of six (6)
watts per square foot, exclusive of heating, ventilation and air conditioning
equipment. Tenant shall not make or perform or permit the making or performing
of, any alterations to wiring, installations or other electrical facilities in
or serving the Demised Premises without the prior consent of Landlord in each
instance, and then only in accordance with the provisions of Article 6.

                                      21
<PAGE>
 
          4.04.  Landlord shall not be liable in any way to Tenant for any
failure or defect in the supply or character of electric energy furnished to the
Demised Premises by reason of any requirement, act or omission of the public
utility providing the Building with electricity or for any other reason
whatsoever (other than Landlord's gross negligence or willful misconduct).
Without limiting the foregoing, in no event shall Landlord be liable to Tenant
for any consequential damages arising from any such failure or defect.

          4.05.  At Landlord's option, Tenant shall purchase from Landlord,
Landlord's agent or Landlord's cleaning contractor all lighting tubes, lamps,
bulbs and ballasts used in the Demised Premises and Tenant shall pay Landlord's
reasonable charges (not to exceed the standard rate generally charged to other
tenants at the Building) for providing and installing same on demand as
additional rent.

                                   ARTICLE 5

                                      USE

          5.01.  The Demised Premises shall be used solely as and for executive
and general offices, including as a data center, and for no other purpose.

          5.02.  Tenant shall not use or permit the use of the Demised Premises
or any part thereof in any way which would violate any of the covenants,
agreements, terms, provisions and conditions of this Lease or for any unlawful
purposes or in any unlawful manner or in violation of the certificate of
occupancy for the Demised Premises or the Building, and Tenant shall not permit
the Demised Premises or any part thereof to be used in any manner or anything to
be done, brought into or kept therein which, in Landlord's good faith judgment
shall impair or interfere with (i) the character, reputation or appearance of
the Building as a first class office building, (ii) any of the Property services
or the proper and economic heating, cleaning, air conditioning or other
servicing of the Property or the Demised Premises, or (iii) the use of any of
the other areas of the Property by, or occasion discomfort, inconvenience or
annoyance to, any of the other tenants or occupants of the Property. Tenant
shall not install any electrical or other equipment of any kind which, in the
judgment of Landlord, might cause any such impairment, interference, discomfort,
inconvenience or annoyance or which might overload the risers or feeders
servicing the Demised Premises or other portions of the Building.

                                   ARTICLE 6

                         ALTERATIONS AND INSTALLATIONS

          6.01.  Tenant shall make no alterations, installations, additions or
improvements in or to the Demised Premises without Landlord's prior written
consent and then only by contractors or mechanics who are approved by Landlord
beforehand or who are on the list of approved contractors for the Complex
prepared by Landlord and furnished to Tenant upon request. Landlord hereby
approves Nova Interiors, Nead Electric and Aztec Corporation to 

                                       22
<PAGE>
 
perform Tenant's Work with respect to the initially Demised Premises. All such
work, alterations, installations, additions and improvements shall be done at
Tenant's sole expense and at such times and in such manner as Landlord may from
time to time reasonably designate.

          Any work in the Demised Premises shall be done solely in accordance
with plans and specifications (prepared by a licensed engineer) first approved
in writing by Landlord. Landlord shall have five (5) days to approve such plans;
provided, that in the event such plans are submitted to third party consultants
for their review, then Landlord shall have ten (10) days to approve such plans,
provided, that in either case, Landlord may extend the time period, as
applicable, by five (5) days by giving notice of same to Tenant by the end of
the original time period, as applicable, provided above.  Tenant shall reimburse
Landlord promptly upon demand for any reasonable costs and expenses incurred by
Landlord in connection with Landlord's review of such Tenant's plans and
specifications.  Landlord will not unreasonably withhold or delay its consent to
requests for non structural alterations, additions and improvements (provided
they will not interfere with the operation of the Complex nor affect the outside
of the Complex nor adversely affect its structure, electrical, HVAC, plumbing or
mechanical systems).

          Any such approved alterations and improvements shall be performed in
accordance with the foregoing and the following provisions of this Article 6:

                1.  All work shall be done in a good and workmanlike manner.

                2.  (a) Any contractor employed by Tenant to perform any work
          permitted by this Lease, and all of its subcontractors, shall agree to
          employ only such labor as will not result in jurisdictional disputes
          or strikes or cause disharmony with other workers employed at the
          Property.  Tenant will inform Landlord in writing of the names of any
          contractor or subcontractors Tenant proposes to use in the Demised
          Premises at least ten (10) days prior to the beginning of work by such
          contractor or subcontractors.

                    (b) Tenant covenants and agrees to pay to the contractor,
          as the work progresses, the entire cost of supplying the materials and
          performing the work shown on Tenant's approved plans and
          specifications less only customary retentions.

                3.  All work shall be performed in compliance with all Legal
          Requirements.

                4.  All work shall be performed in accordance with the general
          tenant guidelines for the Property regarding such work, which
          guidelines Tenant acknowledges are available for its reference and use
          in the Property manager's office.

                5.  Tenant shall keep the Property and the Demised Premises free
          and clear of all liens for any work or material claimed to have been
          furnished to Tenant or to the Demised Premises on Tenant's behalf, and
          all work to be 

                                      23
<PAGE>
 
          performed by Tenant shall be done in a manner which will not
          unreasonably interfere with or disturb other tenants or occupants of
          the Property.

                6.  During the progress of the work to be done by Tenant, said
          work shall be subject to inspection by representatives of Landlord who
          shall be permitted access and the opportunity to inspect, at all
          reasonable times, but this provision shall not in any way whatsoever
          create any obligation on Landlord to conduct such an inspection.

                7.  With respect to alteration or improvement work costing more
          than $50,000, Tenant agrees to pay to Landlord, as additional rent,
          promptly upon being billed therefor, a sum equal to five thousand and
          00/100 Dollars ($5,000) together with all reasonable out of pocket
          expenses, including but not limited to electrical and structural
          engineering costs but excluding attorneys fees and disbursements, for
          Landlord's indirect costs, field inspection and coordination in
          connection with such work (including, without limitation, to review
          Tenant's plans and specifications or to inspect or monitor such
          alteration or improvement work).

                8.  Prior to commencement of any work, Tenant shall furnish to
          Landlord certificates of insurance evidencing the existence of:

                    (a)  worker's compensation insurance covering all persons
          employed for such work with statutory required limits;

                    (b)  employer's liability coverage including bodily injury
          caused by disease with limits of not less than $100,000 per employee;
          and

                    (c)  commercial general liability insurance including, but
          not limited to, completed operations coverage, products liability
          coverage, contractual coverage, broad form property damage,
          independent contractor's coverage and personal injury coverage naming
          Landlord as well as such representatives and consultants of Landlord
          as Landlord shall reasonably specify (collectively "Landlord's
          Consultants"), including, without limitation, as of the date hereof,

          Advisors, as well as Tenant, as additional insureds, with coverage of
          not less than $3,000,000 combined single limit coverage (or such
          higher limits as Landlord may from time to time impose in its
          reasonable judgment).

          Such insurance shall be placed with solvent and responsible companies
          reasonably satisfactory to the Landlord and licensed or authorized to
          do business in the State of New Jersey, and the policies shall provide

          in writing to Landlord.

          including, but not limited to, as of the date hereof Institutional
          Realty Management LLC and Jones Lang Wootton Realty Advisors, harmless
          in accordance with the following clauses (with such modifications
          therein as may be required from time to time by reason of a change in
          the parties constituting Landlord's Consultants):

          "The contractor hereby agrees to the fullest extent permitted by law
          to assume the entire responsibility and liability for and defense of
          and to pay and indemnify Landlord, Tenant and Landlord's Consultants,
          against any loss, cost, expense, liability or damage and will hold
          each of them harmless from and pay any loss, cost, expense, liability
          or damage (including, without limitation, judgments, attorneys' fees,
          court costs, and the cost of appellate proceedings), which Landlord
          and/or Tenant and/or Landlord's Consultants, incurs because of injury
          to or death of any person or on account of damage to property,
          including loss of use thereof, or any other claim arising out of, in
          connection with, or as a consequence of the performance of the work by
          the contractor and/or any acts or omissions of the contractor or any
          of its officers, directors, employees, agents sub-contractors or
          anyone directly or indirectly employed by the contractor or anyone for
          whose acts the contractor may be liable as it relates to the scope of
          this contract, except to the extent with respect to any of the persons
          or entities indemnified hereunder, such injuries to person or damage
          to property are alleged to be due and are held by a final unappealable
          order of a court of competent jurisdiction to be due to the negligence
          of the such person or entity seeking to be so indemnified."

          The contractor's insurance shall specifically insure the foregoing
          hold harmless provision verbatim or such other hold harmless provision
          as is acceptable to Landlord.

                10.  Tenant, to the extent permitted by law, shall make
          application for all building permits in its own name.  Tenant shall
          obtain any temporary certificate of occupancy or addendum to the
          permanent certificate of occupancy required as a result of Tenant's
          alterations and improvements.  Landlord shall join in any and all
          applications for permits, licenses or other authorizations if required
          by any Governmental Authority, and may, in any event, so join in.  If
          Landlord is required to join in any such application Tenant shall
          reimburse Landlord as additional rent for all documented out-of-pocket
          expenses (including without limitation reasonable legal fees and
          expenses) incurred by Landlord in connection with such application.

                11.  Within ninety (90) days after completion of any work Tenant
          shall, at its sole cost and expense, furnish Landlord with one mylar
          set of "as built" plans, drawings and specifications, which plans,
          drawings and specifications and all rights therein, to the extent same
          does not constitute intellectual property of Tenant and Tenant
          notifies Landlord thereof, shall become the property of Landlord.  The
          transfer of all such rights as to the plans shall be confirmed in
          writing by Tenant's architect.  If any of the foregoing plans
          constitute 

                                      25
<PAGE>
 
          intellectual property of Tenant and Tenant notifies Landlord thereof,
          Landlord agrees to keep same confidential, subject to delivery to
          Landlord's agents, employees, attorneys and transactional advisors,
          provided such parties agree to keep any plans delivered to them
          confidential.

                12.  With respect to alteration or improvement work (excluding
          the purchase and maintenance of equipment used exclusively for the
          operation of a data processing center) costing more than $100,000,
          prior to commencing same Tenant shall provide Landlord with a letter
          of credit in the amount of 125% of the reasonable estimated cost of
          such work and otherwise in form and substance reasonably satisfactory
          to Landlord, as security for the full and faithful performance and
          completion of all such work.  Such letter of credit shall be returned
          after such work has been 100% completed and Landlord shall have been
          furnished with payment receipts, lien waivers and such other documents
          as Landlord may reasonably request to assure that such work has been
          completed lien free.

          6.02.  Notice is hereby given that Landlord shall not be liable for
any labor or materials furnished or to be furnished to Tenant upon credit, and
that no mechanic's or other lien for any such labor or materials shall attach to
or affect the reversion or other estate or interest of Landlord in and to the
Demised Premises. Any mechanic's lien filed against the Demised Premises or the
Property for work claimed to have been done for or materials claimed to have
been furnished to Tenant shall be discharged by Tenant at its expense within
thirty (30) days after Tenant receives notice of such filing, by payment, filing
of the bond required by law or otherwise.

          6.03.  All alterations, installations, additions and improvements made
and installed by Landlord, including without limitation all work referred to in
Article 2 hereof and in Schedule C, shall be the property of Landlord and shall
remain upon and be surrendered with the Demised Premises as a part thereof at
the end of the Term.

          6.04.  All alterations, installations, additions and improvements made
and installed by Tenant, or at Tenant's expense, upon or in the Demised Premises
which are of a permanent nature and which cannot be removed without damage to
the Demised Premises or the Property shall become and be the property of
Landlord, and shall remain upon and be surrendered with the Demised Premises as
a part thereof at the end of the Term, except that Landlord shall have the right
at any time up to six months prior to the expiration of the Term to serve notice
upon Tenant that any of such alterations, installations, additions and
improvements shall be removed and, in the event of service of such notice,
Tenant will, at Tenant's own cost and expense, remove the same in accordance
with such request, and restore the Demised Premises to its original condition,
ordinary wear and tear and casualty excepted. Notwith-standing the foregoing,
Tenant shall have the right to remove any and all equipment used exclusively for
the operation of a data processing center, provided Tenant repairs any and all
damage to the Demised Premises or the Property in connection with such removal,
if any, such that Tenant restores the Demised Premises and the Property to the
same condition in which it existed immediately prior to the aforementioned
removal.

                                      26

          6.05.  Where furnished by or at the expense of Tenant all furniture,
furnishings and trade fixtures, including without limitation, murals, business
machines and equipment, counters, screens, grille work, special paneled doors,
cages, partitions, metal railings, closets, paneling, free standing lighting
fixtures and equipment, drinking fountains, refrigeration equipment, and any
other movable property (exclusive of supplementary air conditioning equipment
and raised flooring which shall become the property of Landlord) shall remain
the property of Tenant which may at its option remove all or any part thereof at
any time prior to the expiration of the Term. In case Tenant shall decide not to
remove any part of such property, Tenant shall notify Landlord in writing not
less than three (3) months prior to the expiration of the Term, specifying the
items of property which it has decided not to remove. If, within thirty (30)
days after the service of such notice, Landlord shall request Tenant to remove
any of the said property, Tenant shall at its expense remove the same. As to
such property which Landlord does not request Tenant to remove, the same shall
be, if left by Tenant, deemed abandoned by Tenant and thereupon the same shall
become the property of Landlord.

          6.06.  If any alterations, installations, additions, improvements or
other property which Tenant shall have the right to remove or be requested by
Landlord to remove as provided in Sections 6.04 and 6.05 hereof (herein in this
Section 6.06 called the "Tenant's Property") are not removed on or prior to the
expiration of the Term, Landlord shall have the right to remove the Tenant's
Property and to dispose of the same without accountability to Tenant and at the
sole cost and expense of Tenant. In case of any damage to the Demised Premises
or the Property resulting from the removal of the Tenant's Property, Tenant
shall repair such damage or, in default thereof, shall reimburse Landlord for
Landlord's cost in repairing such damage. This obligation shall survive any
termination of this Lease.

          6.07.  Tenant shall keep records of Tenant's alterations,
installations, additions and improvements costing in excess of $50,000, and of
the cost thereof. Tenant shall, within forty-five (45) days after demand by
Landlord, furnish to Landlord copies of such records if Landlord shall require
same in connection with any proceeding to reduce the assessed valuation of the
Property, or in connection with any proceeding instituted pursuant to Article 14
hereof.

                                    REPAIRS

          7.01.  Tenant shall, at its sole cost and expense, be responsible for
the maintenance and repair of the Demised Premises (including all bathrooms and
other sanitary facilities located therein), and keep same in good order and
condition, including all necessary painting and decorating, and make such
repairs to the Demised Premises and the fixtures and appurtenances therein as
and when needed to preserve them in good working order and condition (except
that as to structural repairs Landlord shall be obligated to make same unless
they are necessitated by any act, omission, occupancy or negligence of Tenant or
by the use of the Demised Premises in a manner contrary to the purposes for
which same are leased to Tenant, in which case Tenant shall be so obligated).
Tenant shall keep all glass, including windows, doors and skylights, clean and
in good condition and repair and Tenant shall replace any glass that may 

                                      27
<PAGE>
 
be damaged with glass of the same kind and quality. All damage or injury to the
Property caused by Tenant moving property in or out of the Building or by
installation or removal of furniture, fixtures or other property, shall be
repaired, restored or replaced promptly by Tenant at its sole cost and expense,
which repairs, restorations and replacements shall be in quality and class equal
to the original work or installations. Tenant shall promptly make all repairs in
or to the Demised Premises or the Property for which Tenant is responsible,
provided that any repairs required to be made to the mechanical, electrical,
sanitary, heating, ventilating, air-conditioning or other Building systems shall
be performed only by Landlord. If Tenant fails to make such repairs, restoration
or replacements, same may be made by Landlord at the expense of Tenant and such
expense shall be collectible as additional rent and shall be paid by Tenant
within ten (10) days after rendition of a bill therefor.

          7.02.  If the Demised Premises includes loading docks, and or related
facilities, Tenant shall keep the loading docks and areas adjacent thereto and
the driveways and streets within the Property leading to said loading docks free
of all dirt, rubbish and other obstructions arising from Tenant's use or
occupancy of any such facilities or the use of such facilities by Tenant's
officers, agents, employees, suppliers or invitees including independent
contractors making deliveries or pick-ups from such loading docks.

          7.03.  Tenant shall not place a load upon any floor of the Demised
Premises exceeding the floor load per square foot area which such floor was
designed to carry and which is allowed by law. The floor of the Demised Premises
will carry 150 pounds live load per square foot of floor space.

          7.04.  Business machines and mechanical equipment used by Tenant which
cause vibration, noise, cold or heat that may be transmitted to the Building
structure or to any leased space to such a degree as to be objectionable to
Landlord or to any other tenant at the Property shall be placed and maintained
by Tenant at its expense in settings of cork, rubber or spring type vibration
eliminators sufficient to absorb and prevent such vibration or noise, or prevent
transmission of such cold or heat. The parties hereto recognize that the
operation of elevators, air conditioning and heating equipment will cause some
vibration, noise, heat or cold which may be transmitted to other parts of the
Building and Demised Premises. Landlord shall be under no obligation to endeavor
to reduce such vibration, noise, heat or cold beyond what is customary in
current good building practice for buildings of the same type as the Building.

          7.05.  Except as otherwise specifically provided in this Lease, there
shall be no allowance to Tenant for a diminution of rental value and no
liability on the part of Landlord by reason of inconvenience, annoyance or
injury to business arising from the making of any repairs, alterations,
additions or improvements in or to any portion of the Building or the Demised-
Premises or in or to fixtures, appurtenances or equipment thereof. Landlord
shall exercise reasonable diligence so as to minimize any interference with
Tenant's business operations, but shall not be required to perform the same on
an overtime or premium pay basis.

          7.06.  If Tenant shall install a supplemental air-conditioning system
subject to and in accordance with the requirements of this Lease, Tenant shall
maintain same in good order and condition, shall enter into a contract for the
maintenance thereof with a heating, ventilating 

                                      28

and air-conditioning contractor reasonably acceptable to Landlord and shall
deliver to Landlord a copy of such contracts and all amendments thereto promptly
after execution thereof.

                                   ARTICLE 8

                              REQUIREMENTS OF LAW

          8.01.  Tenant shall, at Tenant's expense, comply with all Legal
Requirements which shall impose any violation, order or duty upon Landlord or
Tenant with respect to the Demised Premises, or the use or occupation thereof,
whether or not such compliance involves structural repairs or changes, provided
that Tenant shall not be liable for any such compliance relating to
environmental matters, whereby such compliance is required as a direct result of
any act or omission relating to the Demised Premises, which took place prior to
the Commencement Date.

          8.02.  Notwithstanding the provisions of Section 8.01 hereof, Tenant,
at its own cost and expense, in its name and/or (whenever necessary) Landlord's
name, may contest, in any manner permitted by law (including appeals to a court,
or governmental department or authority having jurisdiction in the matter), the
validity or the enforcement of any Legal Requirements with which Tenant is
required to comply pursuant to this Lease, and may defer compliance therewith
provided that:

                 (a)  such non-compliance shall not subject Landlord to criminal
prosecution or subject the Property to lien or sale;

                 (b)  such non-compliance shall not be in violation of any
mortgage, or of any ground or underlying lease or any mortgage thereon;

                 (c)  Tenant shall first deliver to Landlord a surety bond
issued by a surety company of recognized responsibility, or other security
satisfactory to Landlord, indemnifying and protecting Landlord against any loss
or injury by reason of such non-compliance; and

                 (d)  Tenant shall promptly, diligently and continuously
prosecute such contest. Landlord, without expense or liability to it, shall
cooperate with Tenant and execute any documents or pleadings required for such
purpose, provided that Landlord shall reasonably be satisfied that the facts set
forth in any such documents or pleadings are accurate.

          8.03.  All work performed pursuant to this Article by Tenant shall be
performed in accordance with the provisions of Article 6 hereof relating to
Alterations.

                   INSURANCE, LOSS, REIMBURSEMENT, LIABILITY

          9.01.  Tenant shall not do or permit to be done any act or thing upon
the Demised Premises which will invalidate or be in conflict with New Jersey
standard fire insurance policies covering the Property, and fixtures and
property therein, or which would increase the rate of fire insurance applicable
to the Property to an amount higher than it otherwise would be; and Tenant shall
neither do nor permit to be done any act or thing upon the Demised Premises
which shall or might subject Landlord to any liability or responsibility for
injury to any person or persons or to property by reason of any business or
operation being carried on within the Demised Premises.

          9.02.  If, as a result of any act or omission by Tenant or violation
of this Lease, the rate of fire insurance applicable to the Property shall be

Premises issued by the body making fire insurance rates for the Demised Premises
shall be presumptive evidence of the facts stated therein including the items
and charges taken into consideration in fixing the fire insurance rate then
applicable to the Demised Premises.

          9.03.  Landlord or its agents shall not be liable for any injury or
damage to persons or property resulting from fire, explosion, falling plaster,
steam, gas, electricity, water, rain or snow or leaks from any part of the
Building, or from the pipes, appliances or plumbing works or from the roof,
street or subsurface or from any other place or by dampness or by any other
cause of whatsoever nature, unless any of the foregoing shall be caused by or
due to the gross negligence of Landlord, its agents, servants and/or employees.

          9.04.  Landlord or its agents shall not be liable for any damage which
Tenant may sustain if any window of the Demised Premises is broken, or

whatsoever, except only Landlord's arbitrary acts if the result is permanent or
not remedied within a reasonable time, and Tenant shall not be entitled to any
compensation therefor or abatement of rent or to any release from any of
Tenant's obligations under this Lease, nor shall the same constitute an eviction
or constructive eviction.

          9.05.  Tenant shall reimburse Landlord for all expenses, damages or
fines incurred or suffered by Landlord by reason of any breach, violation or 
non-performance by Tenant, or its agents, servants or employees, of any covenant
or provision of this Lease, or by reason of damage to persons or property caused
by moving property of or for Tenant in or out of the Building, or by the
installation or removal of furniture or other property of or for Tenant, or by

                                      30

Property for the satisfaction of any right or remedy of Tenant for the
collection of a judgment (or other judicial process) requiring the payment of
money by Landlord, its partners, officers or shareholders, in the event of any

partners, officers or shareholders shall be subject to levy, execution,

remedies under or with respect to this Lease, the relationship of Landlord, its
partners, officers or shareholders and Tenant hereunder, or Tenant's use and
occupancy of the Demised Premises, or any other liability of Landlord, its
partners, officers or shareholders to Tenant.

          9.08.  (a)  Notwithstanding anything to the contrary contained in this
Lease, Tenant agrees that it will, at its sole cost and expense, include in its
property insurance policies appropriate clauses pursuant to which the insurance
companies (i) waive all right of subrogation against Landlord and any tenant of
space in the Property with respect to losses payable under such policies and
(ii) agree that such policies shall not be invalidated should the insured waive
in writing prior to a loss any or all right of recovery against any party for
losses covered by such policies. Tenant shall furnish Landlord upon demand
evidence satisfactory to Landlord evidencing the inclusion of said clauses in
Tenant's insurance policies.

                 (b)  Provided that Landlord's right of full recovery under its
fire insurance policies is not adversely affected or prejudiced thereby,
Landlord hereby waives any and all right of recovery which it might otherwise
have against Tenant, its servants, agents and employees, for loss or damage
occurring to the Property and the fixtures, appurtenances and equipment therein,
to the extent the same is covered by Landlord's insurance, notwithstanding that
such loss or damage may result from the negligence or fault of Tenant, its
servants, agents or employees. Provided that Tenant's right of full recovery
under its fire insurance policies is not adversely affected or prejudiced
thereby, Tenant hereby waives any and all right of recovery which it might
otherwise have against Landlord, its servants, and employees, and against every
other tenant at the Property who shall have executed a similar waiver as set
forth in this Section 9.08(b) for loss or damage to Tenant's furniture,
furnishings, fixtures and other property removable by Tenant under the
provisions hereof to the extent that same is covered by Tenant's insurance,
notwithstanding that such loss or damage may result from the negligence or fault
of Landlord, its servants, agents or employees, or such other tenant and the
servants, agents or employees thereof.

          9.09.  Tenant covenants and agrees to provide, at its expense, on or
before the Commencement Date and to keep in force during the Term, naming
Landlord, its agents (which as of the date hereof are Institutional Realty
Management LLC and Jones Lang Wootton Realty Advisors), and Tenant as insured
parties, (a) a commercial general liability insurance policy written on an
occurrence form (hereinafter referred to as a "Liability Policy"), including,
without 

                                      31
<PAGE>
 
limitation, blanket contractual liability coverage, premises-operation,
products/completed operations hazard, broad form property damage, independent
contractor's coverage and personal injury coverage protecting Landlord, its
agents, Institutional Realty Management LLC and Jones Lang Wootton Realty
Advisors, and Tenant against any liability whatsoever, occasioned by any
occurrence on or about the Demised Premises or any appurtenances thereto, (b) a
fire and other casualty policy (a "Fire Policy") insuring the full replacement
value of Tenant's Extra Work and all of the furniture, trade fixtures and other
personal property of Tenant located in the Demised Premises against loss or
damage by fire, theft, sprinkler leakage, boiler and machinery and such other
risks or hazards as are insurable under present and future forms of "All Risk"
insurance policies, (c) plate glass insurance, (d) business interruption
insurance and (e) workers compensation and employees liability insurance. Such
policies are to be written by good and solvent insurance companies licensed or
authorized to do business in the State of New Jersey satisfactory to Landlord
with a minimum A.M. Best's rating of A-VI, and shall be in such limits as
Landlord may reasonably require. Landlord reserves the right to increase limits
and adjust coverages as industry standards change. As of the date of this Lease
Landlord reasonably requires limits of liability under (i) the Liability Policy
of not less than $5,000,000 combined single limit per occurrence for bodily or
personal injury (including death) and property damage and (ii) the Fire Policy
equal to the full replacement cost of Tenant's Extra Work, Tenant's Finish Work,
if any, and furniture, trade fixtures and other personal property of Tenant
located at the Property with a deductible of no more than $1,000. Tenant will
furnish Landlord with such information as Landlord may reasonably request from
time to time as to the value of the items specified in clause (ii) above within
ten (10) days after request therefor. Such insurance may be carried (x) under a
blanket policy covering the Demised Premises and other locations of Tenant, if
any, provided that each such policy shall in all respects comply with this
Article and shall specify that the portion of the total coverage of such policy
that is allocated to the Demised Premises is in the amounts required pursuant to
this Section 9.09 and (y) under a primary liability policy of not less than
$1,000,000 and the balance under an umbrella policy. Prior to the time such
insurance is first required to be carried by Tenant and thereafter, at least
fifteen (15) days prior to the effective date of any such policy Tenant shall
deliver to Landlord a certificate evidencing such insurance. Said certificate
shall contain an endorsement that such insurance may not be canceled except upon
thirty (30) days' prior notice to Landlord. All insurance policies carried by
Tenant shall be written as primary policies, not contributing with or secondary
to coverage which Landlord carries. Tenant's failure to provide and keep in
force the aforementioned insurance shall be regarded as a material default
hereunder entitling Landlord to exercise any or all of the remedies provided in
this Lease in the event of Tenant's default. Notwithstanding anything to the
contrary contained in this Lease, the carrying of insurance by Tenant in
compliance with this Section 9.09 shall not modify, reduce, limit or impair
Tenant's obligations and liability under Article 38 hereof.

                                   ARTICLE 10

                         DAMAGE BY FIRE OR OTHER CAUSE

          10.01.  If Plaza II or Plaza III or the Demised Premises shall be
partially or totally damaged or destroyed by fire or other cause (and if this
Lease shall not have been terminated as

                                      32
<PAGE>
 
in this Article 10 hereinafter provided), Landlord shall repair the damage and
restore and rebuild the Building and/or the Demised Premises, except for
Tenant's Work and Tenant's personal property, at its expense with reasonable
dispatch after notice to it of the damage or destruction and the collection of
the insurance proceeds attributable to such damage.

          10.02.   If Plaza II or Plaza III or the Demised Premises shall be
damaged or destroyed by fire or other cause, then unless such fire or damage
shall have resulted from the negligence of Tenant or its employees, agents or
contractors, the rents payable hereunder shall be abated to the extent that the
Demised Premises shall have been rendered untenantable for the period from the
date of such damage or destruction to the date the damage shall be repaired or
restored, such abatement to be granted on a pro rata basis if only a portion of
the Demised Premises is rendered untenantable; provided, however, that should
Tenant reoccupy a portion of the Demised Premises as to which the abatement is
in effect during the period the restoration work is taking place and prior to
the date that the whole of said Demised Premises are made tenantable, Basic
Annual Rent and additional rent allocable to such portion shall be payable by
Tenant from the date of such occupancy.

          10.03.   If Plaza II or Plaza III shall be so damaged or destroyed by
fire or other cause (whether or not the Demised Premises are damaged or
destroyed) as to require a reasonably estimated expenditure made by Landlord or
a reputable contractor designated by Landlord of more than twenty percent (20%)
of the full insurable value of the Building immediately prior to the casualty
(or ten percent (10%) if such casualty occurs during the last two years of the
Term) then Landlord may terminate this Lease by giving Tenant notice to such
effect within one hundred eighty (180) days after the date of the casualty and
upon such notice this Lease and the estate hereby granted, whether or not the
Term shall have theretofore commenced, shall terminate as if that date was the
Expiration Date. In case of any damage or destruction mentioned in this Article
10 which Landlord is required to repair and restore, Tenant may terminate this
Lease by notice to Landlord if Landlord has not completed the making of the
required repairs and restorations within eighteen (18) months after the date of
such damage or destruction, or within such period after such date (not exceeding
six (6) months) as shall equal the aggregate period Landlord may have been
delayed in doing so by Force Majeure Causes (as defined in Article 34).

          10.04.   No damages, compensation or claim shall be payable by
Landlord for inconvenience, loss of business or annoyance arising from any
repair or restoration of any portion of the Demised Premises or of Plaza II or
Plaza 1972 III or of the Complex arising from damage or destruction caused by
fire or other casualty and Landlord shall not be required to do any such repair
or restoration except on Business Days from 9:00 A.M. to 5:00 P.M. Landlord
agrees to use reasonable efforts to perform any such work at such times (between
9:00 A.M. and 5:00 P.M.) and in such a manner as to minimize disturbance to
Tenant's business.

          10.05.   Notwithstanding any of the foregoing provisions of this
Article 10, if Landlord or the lessor of any superior lease or the holder of any
superior mortgage shall be unable to collect all of the insurance proceeds
(including rent insurance proceeds) applicable to damage or destruction of the
Demised Premises or the Property by fire or other cause by reason of some action
or inaction on the part of Tenant or any of its officers, partners, directors,
employees, agents or contractors, then, without prejudice to any other remedies
which may be 

                                      33
<PAGE>
 
available against Tenant, there shall be no abatement of Tenant's rent, but the
total amount of such rent not abated (which would otherwise have been abated)
shall not exceed the amount of uncollected insurance proceeds.

          10.06.   Landlord will not carry separate insurance of any kind on
Tenant's property (including, without limitation, any property of Tenant's which
shall become the property of Landlord as provided in Article 6), and, except as
provided by law or otherwise expressly provided herein, shall not be obligated
to repair any damage thereto or replace or clean the same, or any decorations,
installations, equipment or fixtures installed by or for Tenant at Tenant's
expense.

          10.07.   The provisions of this Article 10 shall be considered an
express agreement governing any cause of damage or destruction of the Demised
Premises by fire or other casualty and any law providing for such a contingency
now or hereinafter erected shall have no application in such case.

                                   ARTICLE 11

                    ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

          11.01.   Except as otherwise expressly provided in this Article 11,
Tenant shall not, whether voluntarily, involuntarily or by operation of law,
without in each instance obtaining the prior consent of Landlord, (a) assign or
otherwise transfer this Lease or the term and estate hereby granted, (b) sublet
all or part of the Demised Premises or allow the same to be used or occupied by
anyone other than Tenant, or (c) mortgage, pledge or encumber this Lease or all
or part of the Demised Premises in any manner by reason of any act or omission
on the part of Tenant. For purposes of this Article 11, (i) the transfer,
directly or indirectly, of a majority of any class of the issued and outstanding
capital stock of any corporate tenant or subtenant, or the transfer of a
majority of the total interest in any other entity (partnership or otherwise)
which is a tenant or subtenant, however accomplished, whether in a single
transaction or in a series of related or unrelated transactions (including,
without limitation, and by way of example only, the transfer of a majority of
the outstanding capital stock of a company which company owns 100% of a second
tier company, which in turn owns more than 50% of the outstanding capital stock
of a corporate tenant hereunder), shall be deemed an assignment of this Lease,
or of such sublease, as the case may be, (ii) a so-called "takeover" agreement
(i.e. an agreement where another entity agrees to become responsible for all or
a portion of Tenant's obligations under this Lease without actually entering
into an assignment or sublease) shall be deemed a transfer of this Lease, (iii)
any person or legal representative of Tenant, to whom Tenant's interest under
this Lease passes by operation of law, or otherwise, shall be bound by the
provisions of this Article 11, and (iv) a modification, amendment or extension
without Landlord's prior written consent of a sublease previously consented to
by Landlord shall be deemed a new sublease. Tenant agrees to furnish to Landlord
upon demand at any time and from time to time such information and assurances as
Landlord may reasonably request that neither Tenant, nor any subtenant, is in
violation of the provisions of this Section 11.01.

                                      34
<PAGE>
 
          11.02.   (a)  The provisions of clauses (a) and (b) of Section 11.01
hereof shall not apply to transactions entered into by Tenant with (i) an
"affiliate" (as hereinafter defined) or (ii) a corporation into or with which
Tenant is merged or consolidated or with an entity to which substantially all of
Tenant's assets are transferred, provided (a) such merger, consolidation or
transfer of assets is for a good business purpose and not principally for the
purpose of transferring the leasehold estate created hereby, and (b) the
assignee or successor entity (upon consummation of such transaction) has a net
worth at least equal to or in excess of the net worth of Tenant either (i)
immediately prior to such merger, consolidation or transfer or (ii) as of the
date hereof, whichever is greater.

                   (b)  For purposes of this Article 11, an affiliate means (i)
a corporation controlled by, controlling or under common control with Tenant (an
"affiliated corporation") or (ii) a partnership or joint venture in which Tenant
or an affiliated corporation owns more than 50% of the general partnership or
joint venture interest therein. Without limiting the generality of the
foregoing, a corporation shall not be deemed controlled by another entity unless
more than 50% of each class of its outstanding capital stock is owned, both
beneficially and of record, by such entity.

                   (c)  The provisions regarding the transfer of the capital
stock of a corporate tenant set forth in Section 11.01 shall not apply to any
corporation where all of its outstanding capital stock is listed on a national
securities exchange (as defined in the Securities Exchange Act of 1934, as
amended) or is traded in the "over the counter" market with quotations reported
by the National Association of Securities Dealers.

          11.03.   Any assignment or transfer, whether made with Landlord's
consent as required by Section 11.01 or without Landlord's consent pursuant to
Section 11.02, shall not be effective unless and until (a) the assignee shall
execute, acknowledge and deliver to Landlord a recordable agreement, in form and
substance reasonably satisfactory to Landlord, whereby the assignee shall (i)
assume the obligations and performance of this Lease and agree to be personally
bound by all of the covenants, agreements, terms, provisions and conditions
hereof on the part of Tenant to be performed or observed on and after the
effective date of any such assignment and (ii) agree that the provisions of this
Article 11 shall, notwithstanding such assignment or transfer, continue to be
binding upon it in the future, and (b) in the case of an assignment or transfer
pursuant to Section 11.02, Tenant or its successor shall have delivered to
Landlord financial statements certified by a reputable firm of certified public
accountants evidencing satisfaction of the net worth requirements referred to in
Section 11.02. Tenant covenants that, notwithstanding any assignment or
transfer, whether or not in violation of the provisions of this Lease, and
notwithstanding the acceptance of Basic Annual Rent by Landlord from an assignee
or transferee or any other party, Tenant shall remain fully and primarily and
jointly and severally liable for the payment of the Basic Annual Rent and all
additional rent due and to become due under this Lease and for the performance
and observance of all of the covenants, agreements, terms, provisions and
conditions of this Lease on the part of Tenant to be performed or observed.

          11.04.   The liability of Tenant, and the due performance by Tenant of
the obligations on its part to be performed under this Lease, shall not be
discharged, released or
                                      35
<PAGE>
 
impaired in any respect by an agreement or stipulation made by Landlord or any
grantee or assignee of Landlord in connection with a mortgage or any other
agreement with a third party extending the time of or modifying any of the
obligations contained in this Lease, or by any waiver or failure of Landlord to
enforce any of the obligations on Tenant's part to be performed under this
Lease, and Tenant shall continue liable hereunder. If any such agreement or
modification operates to increase the obligations of Tenant under this Lease,
the liability under this Section 11.04 of the tenant named in the Lease or any
of its successors in interest (unless such party shall have expressly consented
in writing to such agreement or modification) shall continue to be no greater
than if such agreement or modification had not been made.

          11.05.   (a) If Tenant desires to assign or sublet all or part of the
Demised Premises, other than as provided in Section 11.02, it shall notify
Landlord in writing of its intention to do so specifying in such notice whether
it wishes to assign or sublet and if to sublet whether it is for all or part of
the Demised Premises and if for only a part thereof specifying on a plan such
portion thereof ("Notice of Intent"). Landlord shall have the right, but not the
obligation, (i) with respect to a proposed assignment of this Lease or
subletting of the entire Demised Premises, to terminate this Lease as of the
"Termination Date" (as hereinafter defined) as to all of the Demised Premises,
(ii) with respect to a proposed subletting of only a portion of the Demised
Premises for substantially the balance of the Term, to terminate this Lease with
respect to such portion of the Demised Premises as of the Termination Date and
(iii) with respect to a proposed subletting of only a portion of the Demised
Premises for less than substantially the balance of the Term, accept a sublease
from Tenant of such portion as of the Termination Date. Within thirty (30) days
after Landlord receives Tenant's Notice of Intent, Landlord shall notify Tenant
whether it elects to terminate this Lease as to all or the applicable portion of
the Demised Premises or sublease a portion of the Demised Premises, as the case
may be ("Response Notice"). If Landlord elects to so terminate this Lease or
sublease a portion of the Demised Premises, the Response Notice shall set forth
the date (the "Termination Date") as of which this Lease shall so terminate or
such sublease shall be effective, which date shall not be earlier than six
months nor later than one year after the date Landlord delivers the Response
Notice. For purposes hereof a sublease shall be deemed to be for substantially
the balance of the Term if the term thereof, together with any renewal terms to
which the subtenant is entitled in the event it exercises all options granted to
it by Tenant, shall be for substantially the balance of the Term of this Lease.

                   (b) (i) If in the Response Notice Landlord elects to
terminate this Lease with respect to the entire Demised Premises, Tenant shall
promptly execute and deliver to Landlord an instrument in form satisfactory to
Landlord modifying this Lease so that the Term shall expire as of the
Termination Date.

          (ii)  If in the Response Notice Landlord elects to terminate this
          Lease with respect to only a portion of the Demised Premises, (x)
          Tenant shall promptly execute and deliver to Landlord an appropriate
          modification of this Lease (including the adjustment of Basic Annual
          Rent and the additional rent payable pursuant to Article 3 in
          proportion to that portion of the Demised Premises affected by such
          termination) in form satisfactory to Landlord providing for such
          termination as of the Termination Date and (y) Landlord shall, at
          Tenant's sole cost and expense, 

                                      36
<PAGE>
 
          perform all work, including the erection of demising walls, necessary
          to physically separate the portion of the Demised Premises so released
          from the Lease from the remainder of the Demised Premises. In
          addition, if the portion of the Demised Premises so released from the
          Lease does not have direct access to a public corridor in the Building
          Landlord shall construct, at Tenant's sole cost and expense, such a
          means of access. All amounts payable to Landlord hereunder shall be
          paid simultaneously with the execution of any instrument confirming
          the termination of the Lease as to all or part of the Demised Premises
          contemplated hereby.

          (iii)  If in the Response Notice Landlord elects to sublease a portion
          of the Demised Premises, Tenant shall promptly execute and deliver to
          Landlord a sublease with Landlord or Landlord's designee in form
          reasonably satisfactory to Landlord's and Tenant's counsel and on all
          the terms contained in this Lease, except that:

                         (A)  the rental terms shall be those specified in this
               Lease on a per rentable square foot basis;

                         (B)  the sublease shall not provide for any work to be
               done for the subtenant or for any initial rent concessions or
               contain provisions inapplicable to a sublease, except that Tenant
               shall pay to subtenant the cost of performing all work, including
               the erection of demising walls, necessary to physically separate
               the subleased premises from the remainder of the Demised Premises
               and to provide direct access thereto from a public corridor in
               the Building (if the subleased premises does not have such
               access);

                         (C)  the subtenant thereunder shall have the right to
               underlet the subleased premises, in whole or in part, or assign
               the sublease, without Tenant's consent;

                         (D)  the subtenant thereunder shall have the right to
               make, or cause to be made, any changes, alterations, decorations,
               additions and improvements that such subtenant may desire or
               authorize;

                         (E)  the sublease shall expressly negate any intention
               that any estate created by or under such sublease be merged with
               any other estate held by either of the parties thereto;

                         (F)  any consent required of Tenant, as lessor under
               that sublease, shall be deemed granted if consent with respect
               thereto is granted by Landlord;

                         (G)  there shall be no limitation as to the use of the
               sublet premises by the subtenant thereunder;

                                      37
<PAGE>
 
                         (H)  any failure of the subtenant thereunder to comply
               with the provisions of the sublease, other than with respect to
               the payment of rent to Tenant, shall not constitute a default
               thereunder if Landlord has consented to such non-compliance by
               subtenant or a default by Tenant hereunder; and

                         (I)  such sublease shall provide that Tenant's
               obligations with respect to vacating the Demised Premises and
               removing any changes, alterations, decorations, additions or
               improvements made in the subleased premises shall be limited to
               those which accrued and related to such of the foregoing as were
               made prior to the effective date of the sublease.

               (c)  Tenant shall reimburse Landlord on demand for any costs
incurred by Landlord to review a Notice of Intent, including without limitation
any reasonable attorneys' fees, which payment shall be payable even if Tenant
subsequently withdraws same.

               (d)  If Landlord shall not elect to terminate this Lease or
sublease a portion of the Demised Premises as set forth in paragraph (a) above,
Landlord shall not unreasonably withhold or delay its consent to an assignment
of this Lease or subletting of all or a portion of the Demised Premises as set
forth in the Notice of Intent provided the provisions of Section 11.06 are
complied with and provided further that such assignment or subletting is
accomplished within 180 days following the giving of the Response Notice failing
which Tenant must again comply with the provisions of this Section 11.05.

       11.06.  Landlord shall not unreasonably withhold or delay its consent
to an assignment of this Lease or a subletting of the whole or a part of the
Demised Premises provided:

               (a)  Tenant shall have complied with the provisions of Section
11.05 and Landlord shall not have made any of the termination elections provided
for therein.

               (b)  Tenant shall furnish Landlord with the name and business

Landlord;

               (c)  The proposed subtenant or assignee is a reputable party
whose financial net worth, credit and financial responsibility is, considering
the responsibilities involved and the standards of Landlord in those respects
for the Building, reasonably satisfactory to Landlord;

               (d)  Tenant shall deliver an executed assignment or sublease to
Landlord at the time Landlord's consent is requested;

               (e)  The nature and character of the proposed subtenant or
assignee, its business or activities and intended use of the Demised Premises
are, in Landlord's reasonable 

                                      38
<PAGE>
 
judgment, in keeping with the standards of the Building and the floor or floors
on which the Demised Premises are located;

               (f)  The proposed subtenant or assignee is not then an occupant

(i) it is subject to all of the terms, covenants, agreements, provisions, and
conditions of this Lease, (ii) the subtenant or assignee, as the case may be,

               (i)  Tenant shall reimburse Landlord on demand for any costs

<PAGE>
 
                  (n)  Landlord and Tenant shall have agreed on the computation
required by Section 11.07 hereof.

          limited to, sums paid for the sale or rental of Tenant's fixtures,
          leasehold improvements, equipment, furniture, furnishings or other
          personal property, less, in the case of the sale thereof, the net

          and additional rent accruing during the term of the sublease in
          respect of the subleased space (at the rate per square foot payable by
          Tenant hereunder) pursuant to the terms hereof (including, but not
          limited to, sums paid for the sale or rental of Tenant's fixtures,
          leasehold improvements, equipment, furniture, furnishings or other

          limitation, costs of altering and preparing the Demised Premises for

and when paid by the assignee or subtenant to Tenant.

          11.08.  If Landlord exercises any of its options under Section 11.05,
Landlord shall be free to, and shall have no liability to Tenant, if Landlord
shall lease the Demised Premises or any portion thereof with respect to which

the case may be if any such proposed assignee or subtenant shall exist.

or damage and to support the same by proper foundations without any claim for
damages or indemnity against Landlord, or diminution or abatement of rent.

                                   ARTICLE 14

                                  CONDEMNATION

          14.01.  (a)  If all or substantially all of the Demised Premises shall
be lawfully condemned or taken by any Governmental Authority (as defined in
Article 22 (hereinafter "Condemned")), this Lease and the estate granted hereby
shall terminate as of the date of vesting of title in such Governmental
Authority.

                  (b)  If less than all or substantially all of the rentable
area of the Demised Premises shall be Condemned, then this Lease shall continue
in effect as to the remaining portion of the Demised Premises but shall
terminate as to the portion so Condemned as of the date of vesting of title in
the Governmental Authority; provided, however, that if 25% or more of the
rentable area of the Demised Premises shall be Condemned, either Landlord or
Tenant may, at their option, terminate this Lease and the estate granted hereby
by giving written notice to the other within thirty (30) days after Landlord
shall have received notice of the vesting of title in the Governmental Authority
(a copy of which notice Landlord shall deliver to Tenant promptly after receipt
thereof) in which event this Lease and the estate granted hereby shall terminate
as of the last day of the month next succeeding the month in which such notice
is given.

                                      41
<PAGE>
 
                  (c)  If twenty five percent (25%) or more of Plaza II or Plaza
III or of the Complex (whether or not the Demised Premises is affected) shall be
Condemned or if so much of the parking area located on the Land shall be
Condemned so that the number of parking spaces remaining shall in Landlord's
judgment be insufficient for the continued operation of the Building or the
Complex, Landlord may, at Landlord's option, terminate this Lease and the estate
granted hereby by written notice given to Tenant within thirty (30) days after
Landlord shall have received notice of the vesting of title in the Governmental
Authority (a copy of which notice Landlord shall deliver to Tenant promptly
after receipt thereof) in which event this Lease and the estate granted hereby
will terminate on the last day of the month next succeeding the month in which
such notice is given.

                  (d)  If neither Landlord nor Tenant elects to terminate this
Lease pursuant to paragraph (b) or (c) above, this Lease shall be and remain
unaffected by such condemnation, except that the Basic Annual Rent and the
additional rent payable under Article 3 shall be abated effective as of the date
of the vesting of title in the Governmental Authority in proportion to the
reduction in the rentable area of the Demised Premises resulting from such
condemnation.

          14.02.  In the event of termination of this Lease in any of the cases
herein before provided, this Lease and the term and estate hereby granted shall
expire as of the date of such termination with the same effect as if that were
the Expiration Date, and the Basic Annual Rent and additional rent payable
hereunder shall be apportioned as of such date.

          14.03.  In the event of any condemnation of all or a part of the
Property, Landlord shall be entitled to receive the entire award in the
condemnation proceeding, including any award made for the value of the estate
vested by this Lease in Tenant.  Tenant hereby expressly assigns to Landlord any
and all right, title and interest of Tenant now or hereafter arising in or to
any such award or any part thereof, including, without limitation, any award for
the unexpired portion of the Term and agrees that it shall not be entitled to
receive any part of such award. Tenant shall, however, be entitled to make a
separate claim in such proceeding for loss of good will and moving expenses
provided such award is in addition to and not in reduction of Landlord's award
from the Governmental Authority.

          14.04.  In the event of any partial taking which does not result in a
termination of this Lease, Landlord, at its expense, shall proceed with
reasonable diligence to repair, alter and restore the remaining parts of the
Building and the Demised Premises to substantially their former condition to the
extent that the same may be feasible and so as to constitute a complete and
tenantable Building and Demised Premises except for Tenant's leasehold
improvements, furniture, furnishings, equipment and decorations, which shall be
repaired, altered and restored by Tenant at its expense.  Landlord's obligation
under this Section 14.04 shall be limited in dollar amount to the net award
(after deducting all expenses incurred in obtaining same) available from the
Governmental Authority for the improvements taken or conveyed (exclusive of the
award for the Land or any portion thereof).

          14.05.  If the temporary use or occupancy of all or any part of the
Demised Premises shall be taken during the Term, Tenant shall be entitled,
except as hereinafter set forth, to receive that portion of the award or payment
for such taking which represents compensation 

                                      42
<PAGE>
 
for the use and occupancy of the Demised Premises (or portion thereof taken) and
for moving expenses, and Landlord shall be entitled to receive that portion
which represents reimbursement for the cost of restoration of the Demised
Premises. This Lease shall be and remain unaffected by such taking and Tenant
shall continue to be responsible for all of its obligations hereunder insofar as
such obligations are not affected by such taking and shall continue to pay Basic
Annual Rent and additional rent in full when due. If the period of temporary use
or occupancy shall extend beyond the Expiration Date, that part of the award or
payment which represents compensation for the use and occupancy of the Demised
Premises (or portion thereof taken) shall be divided between Landlord and Tenant
so that Tenant shall receive so much thereof as represents compensation for the
period up to and including the Expiration Date and Landlord shall receive so
much thereof as represents compensation for the period after the Expiration
Date.

                                   ARTICLE 15

                      ACCESS TO DEMISED PREMISES; CHANGES

          15.01.  Tenant shall permit Landlord to erect, use and maintain pipes,
ducts and conduits in and through the Demised Premises, provided the same are
installed adjacent to or concealed behind walls and ceilings of the Demised
Premises.  Landlord shall, to the extent practicable, install such pipes, ducts
and conduits by such methods and at such locations as will not materially
interfere with or impair Tenant's layout or use of the Demised Premises.
Landlord or its agents or designees shall have the right, but only upon notice
to Tenant or any authorized employee of Tenant at the Demised Premises, to enter
the Demised Premises, during and after business hours, at Landlord's option, (a)
for the making of such repairs or alterations or improvements as Landlord may
deem, in its sole judgment, necessary or appropriate for the Building or which
Landlord shall be required to or shall have the right to make by the provisions
of this Lease or any other lease in the Complex and (b) for the purpose of
inspecting them or exhibiting them to existing or prospective purchasers,
mortgagees or lessees of all or part of the Land, Building or Property or to
prospective assignees, agents or designees of any such parties. Landlord shall
be allowed to take all material into and upon the Demised Premises that may be
required for the repairs or alterations or improvements above mentioned and may
take over discrete portions of the Demised Premises not in excess of five
percent (5%) at any one time to the extent necessary to perform such work or to
ensure the safety of Tenant's personnel without the same constituting an actual
or constructive eviction of Tenant in whole or in part, and the rent reserved
hereunder shall not abate while said repairs or alterations or improvements are
being made by reason of loss or interruption of the business of Tenant because
of the prosecution of any such work.  Landlord shall exercise reasonable
diligence so as to minimize the disturbance to Tenant but nothing contained
herein shall be deemed to require Landlord to perform the same on an overtime or
premium pay basis.

          15.02.  Landlord reserves the right, without the same constituting an
actual or constructive eviction and without incurring liability to Tenant
therefor, to change the arrangement and/or location of public entrances,
passageways, doors, doorways, corridors, elevators, stairways, toilets and other
public parts of the Building and common areas of the Complex (including without
limitation the Piers and parking areas); provided, however, that 

                                      43
<PAGE>
 
access to the Building shall not be cut off and that there shall be no
unreasonable obstruction of access to the Demised Premises.

          15.03.  Landlord may, at reasonable times and upon reasonable advance
notice to Tenant, (a) during the twelve (12) months prior to expiration of the
Term exhibit the Demised Premises to prospective tenants and (b) at any time
during the Term, exhibit the Demised Premises to actual and prospective holders
of Superior Instruments or purchasers of all or any portion of the Complex.

          15.04.  If Tenant shall not be personally present to open and permit
an entry into the Demised Premises at any time when for any reason an entry
therein shall be urgently necessary by reason of fire or emergency, Landlord or
Landlord's agents may forcibly enter the same without rendering Landlord or such
agents liable therefor (if during such entry Landlord or Landlord's agents shall
accord reasonable care to Tenant's property) and without in any manner affecting
the obligations and covenants of this Lease.

                                   ARTICLE 16

                            CONDITIONS OF LIMITATION

          16.01.  This Lease and the term and estate hereby granted are subject
to the limitation that whenever Tenant or any guarantor of Tenant's obligations
hereunder shall become insolvent or generally fail to pay, or admit in writing
its inability to pay, debts as they become due; or Tenant or any such guarantor
shall apply for, consent to, or acquiesce in, the appointment of a trustee,
receiver, sequestrator or other custodian for Tenant or such guarantor or any
property of any thereof, or make a general assignment for the benefit of
creditors; or, in the absence of such application, consent or acquiescence, a
trustee, receiver, sequestrator or other custodian shall be appointed for Tenant
or any such guarantor or for a substantial part of the property of any thereof
and not be discharged within 30 days; or any bankruptcy, reorganization, debt
arrangement, or other case or proceeding under any bankruptcy or insolvency law,
or any dissolution, winding up or liquidation proceeding, shall be commenced in
respect of Tenant or any such guarantor, and, if not commenced by Tenant or such
guarantor, be consented to or acquiesced in by Tenant or such guarantor, shall
result in the entry of an order for relief or shall remain for thirty (30) days
undismissed; or Tenant or any such guarantor shall take any corporate action to
authorize, or in furtherance of, any of the foregoing, then Landlord may at any
time after receipt of notice of the occurrence of any such event, give Tenant a
notice of intention to end the Term at the expiration of five (5) days from the
date of service of such notice of intention, and upon the expiration of said 5
day period this Lease and the term and estate hereby granted, whether or not the
Term shall theretofore have commenced, shall terminate with the same effect as
if that day were the Expiration Date, but Tenant shall remain liable for damages
as provided in Article 18.

          16.02.  This Lease and the term and estate hereby granted are subject
to further limitation as follows:

                                      44
<PAGE>
 
               (a)  whenever Tenant shall fail to pay any installment of Basic
Annual Rent or any additional rent or any other charge payable by Tenant to
Landlord, on the day the same is due and payable pursuant to the terms hereof,
and such default shall continue for five (5) days after Landlord shall have
given Tenant a notice specifying such default, or

               (b)  whenever Tenant shall do or permit anything to be done,
whether by action or inaction, contrary to any of Tenant's obligations hereunder
(except as provided in clauses (a), (c), (d), (e) and (f) of this Section 16.02)
and if such situation shall continue and shall not be remedied by Tenant within
fifteen (15) days after Landlord shall have given to Tenant a notice specifying
the same, or, in the case of a happening or default which cannot with due
diligence be cured within a period of fifteen ( 15) days and the continuation of
the period required for cure will not subject Landlord to the risk of criminal
liability (as more particularly described in Article 8 hereof) or termination of
any superior lease or foreclosure of any superior mortgage, if Tenant shall not
(i) within said fifteen (15) day period advise Landlord of Tenant's intention to
duly institute all steps necessary to remedy such situation and (ii) duly
institute within said fifteen (15) day period, and thereafter diligently and
continuously prosecute to completion, all steps necessary to remedy the same, or

               (c)  whenever any event shall occur or any contingency shall
arise whereby this Lease or the estate hereby granted or the unexpired balance
of the Term hereof would, by operation of law or otherwise, devolve upon or pass
to any person, firm or corporation other than Tenant, except as expressly
permitted by Article 11, or

               (d)  whenever Tenant shall vacate or abandon the Demised Premises
for a continuous period of at least thirty (30) days (unless as a result of a
casualty), or

               (e)  whenever Tenant shall default in complying with the
provisions of Section 6.02 with respect to the discharge of mechanic's liens
within the time period therein provided, or

               (f)  whenever Tenant shall default in the due keeping, observing
or performance of any covenant, agreement, provision or condition of Article 5
hereof on the part of Tenant to be kept, observed or performed and if such
default shall continue and shall not be remedied by Tenant within three (3)
business days after Landlord shall have given to Tenant a notice specifying the
same, then in any of said cases set forth in the foregoing clauses (a), (b),
(c), (d), (e) and (f), Landlord may give to Tenant a notice of intention to end
the Term at the expiration of five (5) days from the date of the service of such
notice of intention, and upon the expiration of said five (5) days this Lease
and the term and estate hereby granted, whether or not the Term shall
theretofore have commenced, shall terminate with the same effect as if that day
were the Expiration Date, but Tenant shall remain liable for damages as provided
in Article 18.

                        RE-ENTRY BY LANDLORD, INJUNCTION

          17.01.  If Tenant shall fail to pay any installment of Basic Annual
Rent, or of any additional rent payable by Tenant to Landlord on the date the
same is due and payable, and if such default shall continue for five (5) days
after Landlord shall have given to Tenant a notice specifying such default, or
if this Lease shall terminate as in Article 16 provided, Landlord or Landlord's
agents and employees may immediately or at any time thereafter re-enter the
Demised Premises, or any part thereof, either by summary dispossess proceedings
or by any suitable action or proceeding at law, or otherwise, without being
liable to indictment, prosecution or damages therefrom.  The word re-enter, as
herein used, is not restricted to its technical legal meaning.

          17.02.  In the event of a breach or threatened breach by Tenant of any
of its obligations under this Lease, Landlord shall also have the right of
injunction.  The special remedies to which Landlord may resort hereunder are
cumulative and are not intended to be exclusive of any other remedies or means
of redress to which Landlord may lawfully be entitled at any time and Landlord
may invoke any remedy allowed at law or in equity as if specific remedies were
not provided for herein.

          17.03.  If this Lease shall terminate under the provisions of Article
16, or if Landlord shall re-enter the Demised Premises under the provisions of
this Article 17, or in the event of the termination of this Lease, or of re-
entry by or under any summary dispossess or other proceeding or action or any
provision of law by reason of default hereunder on the part of Tenant, then (a)
Tenant shall thereupon pay to Landlord the Basic Annual Rent and additional rent
payable by Tenant to Landlord up to the time of such termination of this Lease,
or of such recovery of possession of the Demised Premises by Landlord, as the
case may be, and shall also pay to Landlord damages as provided in Article 18,
and (b) Landlord shall be entitled to retain all moneys, if any, paid by Tenant
to Landlord, whether as advance rent, security or otherwise, but such moneys
shall be credited by Landlord against any Basic Annual Rent or additional rent
due from Tenant at the time of such termination or re-entry or, at Landlord's
option, against any damages payable by Tenant under Articles 16 and 18 or
pursuant to law.

          17.04.  Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws in the event of Tenant
being evicted or dispossessed for any cause, or in the event of Landlord
obtaining possession of the Demised Premises, by reason of the violation by
Tenant of any of the covenants and conditions of this Lease or otherwise

                                   ARTICLE 18

                                    DAMAGES

          18.01.  If this Lease is terminated under the provisions of Article
16, or if Landlord shall re-enter the Demised Premises under the provisions of
Article 17, or in the event of the termination of this Lease, or of re-entry by
or under any summary dispossess or other 

                                      46
<PAGE>
 
proceeding or action or any provision of law by reason of default hereunder on
the part of Tenant, Tenant shall pay to Landlord as damages, at the election of
Landlord, either

               (a)  a sum which at the time of such termination of this Lease or
at the time of any such re-entry by Landlord, as the case may be, represents the
then value of the excess, if any, of

                    (1) the aggregate of the Basic Annual Rent and the
          additional rent payable hereunder which would have been payable by
          Tenant (conclusively presuming the additional rent to be the same as
          was payable for the year immediately preceding such termination except
          that additional rent on account of Taxes and Property Expenses shall
          be presumed to increase at the average of the rates of increase
          thereof previously experienced by Landlord during the period (not to
          exceed 3 years) prior to such termination) for the period commencing
          with such earlier termination of this Lease or the date of any such
          re-entry, as the case may be, and ending with the Expiration Date, had
          this Lease not so terminated or had Landlord not so re-entered the
          Demised Premises, over

                    (2) the aggregate rental value of the Demised Premises for
          the same period, or

               (b)  sums equal to the Basic Annual Rent and the additional rent
payable hereunder which would have been payable by Tenant had this Lease not so
terminated, or had Landlord not so re-entered the Demised Premises, payable upon
the due dates therefor specified herein following such termination or such re-
entry and until the Expiration Date; provided, however, that if Landlord shall
re-let the Demised Premises during said period, Landlord shall credit Tenant
with the net rents received by Landlord from such re-letting, such net rents to
be determined by first deducting from the gross rents as and when received by
Landlord from such reletting, the expenses incurred or paid by Landlord in
terminating this Lease or in re-entering the Demised Premises and in securing
possession thereof, as well as the expenses of re-letting, including altering
and preparing the Demised Premises for new tenants, brokers' commissions, legal
fees, and all other expenses properly chargeable against the Demised Premises
and the rental thereof; it being understood that any such re-letting may be for
a period shorter or longer than the remaining term of this Lease.  In no event
shall Tenant be entitled to receive any excess of such net rents over the sums
payable by Tenant to Landlord hereunder for the period of such re-letting, nor
shall Tenant be entitled in any suit for the collection of damages pursuant to
this subsection to a credit in respect of any net rents from a re-letting,
except to the extent that such net rents are actually received by Landlord.  If
the Demised Premises or any part thereof should be re-let in combination with
other space, then proper apportionment on a square foot basis shall be made of
the rent received from such re-letting and of the expenses of re-letting.

          If the Demised Premises or any part thereof be re-let by Landlord for
the unexpired portion of the term of this Lease, or any part thereof, before
presentation of proof of such damages to any court, commission or tribunal, the
amount of rent payable pursuant to such re-letting shall, prima facie, be the
fair and reasonable rental value for the Demised Premises, or part thereof, so
re-let during the term of the re-letting.

          18.02.  Suit or suits for the recovery of such damages, or any
installments thereof, may be brought by Landlord from time to time at its
election, and nothing contained herein shall be deemed to require Landlord to
postpone suit until the date when the Term would have expired if it had not been
so terminated under the provisions of Article 16, or under any provision of law,
or had Landlord not re-entered the Demised Premises.  Nothing herein contained
shall be construed to limit or preclude recovery by Landlord against Tenant of
any sums or damages to which, in addition to the damages particularly provided
above, Landlord may lawfully be entitled by reason of any default hereunder on
the part of Tenant.  Nothing herein contained shall be construed to limit or
prejudice the right of Landlord to prove for and obtain as liquidated damages by
reason of the termination of this Lease or re-entry of the Demised Premises for
the default of Tenant under this Lease, an amount equal to the maximum allowed
by any statute or rule of law in effect at the time when, and governing the
proceedings in which, such damages are to be proved whether or not such amount
be greater, equal to, or less than any of the sums referred to in Section 18.01.

                                   ARTICLE 19

                LANDLORD'S RIGHT TO PERFORM TENANT'S OBLIGATIONS

          19.01.  If Tenant shall default in the observance or performance of
any term or covenant on Tenant's part to be observed or performed under any of
the terms or provisions of this Lease, (a) Landlord may, but in no event shall
be required to, remedy such default for the account of Tenant, immediately and
without notice in case of emergency, or in any other case if Tenant shall fail
to remedy such default after Landlord shall have notified Tenant in writing of
such default and the applicable grace period for curing such default shall have
expired; and (b) if Landlord makes any expenditures or incurs any obligations
for the payment of money in connection with such default, including without
limitation, reasonable attorneys' fees in instituting, prosecuting or defending
any action or proceeding, such sums paid or obligations incurred, with interest
at the Interest Rate from the date paid or incurred, shall be deemed to be
additional rent hereunder and shall be paid by Tenant to Landlord upon rendition
of a bill to Tenant therefor.  The provisions of this Article 19 shall survive
the expiration or other termination of this Lease.

                                   ARTICLE 20

                                QUIET ENJOYMENT

          20.01.  Landlord covenants and agrees that subject to the terms and
provisions of this Lease, if, and so long as, Tenant keeps and performs each and
every covenant, agreement, term, provision and condition herein contained on the
part or on behalf of Tenant to be kept or performed, then Tenant's rights under
this Lease shall not be cut off or ended before the expiration of the term of
this Lease, subject however, to the provisions of this Lease (including without
limitation, the provisions of Article 25 hereof with respect to Superior
Instruments (as defined in Article 25 hereof) which affect this Lease).

                             SERVICES AND EQUIPMENT

          21.01. Landlord shall:

                 (a)  Provide necessary passenger elevator facilities on
Business Days from 8:00 A.M. to 6:00 P.M. and shall have at least one elevator
subject to call at all other times. At Landlord's option, the elevators shall be
operated by automatic control or by manual control, or by a combination of both
of such methods. Tenant shall use passenger elevators solely for the
transportation of its employees and invitees and not for freight handling, the
delivery of packages requiring hand trucks or other similar items or the removal
of refuse.

                 (b)  Provide freight elevator service on Business Days from
9:00 A.M. to 12:00 Noon and 12:30 P.M. to 5:00 P.M. All deliveries to Tenant
shall be made at freight docks located on the ground floor or at such other
locations as Landlord may from time to time designate.

                 (c)  Maintain and keep in good order and repair (i) the air
conditioning, heating and ventilating unit existing on the date of this Lease in
the Fourth Floor Space and (ii) the other base building structural systems in
accordance with Section 7.01; it being understood that in no event shall
Landlord be responsible for the maintenance or repair of any other air
conditioning, heating or ventilating systems (on portions thereof) (whether
installed by Landlord or Tenant), including, without limitation, systems that
are installed to service Tenant's data processing, computer or telephone
operations.  Landlord shall provide reasonable amounts of condenser water to the
Demised Premises from locations designated by Landlord 24 hours per day, 7 days
per week.  Tenant shall have the right to tap into the Building's condenser
water riser via the tap currently located on the 8th floor of Plaza III;
provided, that the performance of such work shall be performed in accordance
with Article 6 and all other applicable provisions of this Lease.  Tenant
acknowledges that Tenant shall be responsible for installing, at its sole cost
and expense, heating, ventilation and air conditioning equipment in the Demised
Premises (other than the existing 4th floor unit).  Landlord has informed Tenant
that the windows of the Demised Premises and the Building are sealed, and that
the Demised Premises may become uninhabitable and the air therein may become
unbreathable without such equipment or during the hours or days when Landlord is
not able to furnish condenser water to the Demised Premises.  Any use or
occupancy of the Demised Premises without such equipment or during such hours
shall be at the sole risk, responsibility and hazard of Tenant, and Landlord
shall have no responsibility or liability therefor.  Such condition of the
Demised Premises shall not constitute nor be deemed to be a breach or a
violation of this Lease or of any provision thereof, nor shall it be deemed an
actual or constructive eviction nor shall Tenant claim or be entitled to claim
any abatement of rent nor make any claim for any damages or compensation by
reason of such condition of the Demised Premises.  Nothing contained herein
shall be deemed to require Landlord to furnish at Landlord's expense such
electric energy as is required to operate the air conditioning system serving
the Demised Premises.  Subject to the provisions of Article 4 hereof all such
electric energy shall be furnished to Tenant at Tenant's cost and expense.

<PAGE>
 
               (d)  Provide the cleaning and janitorial services described on
Schedule E annexed hereto on Business Days.  In the event Landlord's cost of
providing such services to the Existing Buildings shall increase after the date
hereof, Tenant agrees to pay to Landlord as additional rent on the first day of
each and every month after such increase an amount equal to Tenant's Expense
Share of the monthly increase of Landlord's cost of providing such services to
the Existing Buildings.  Landlord shall promptly notify Tenant of any such
increase.  Tenant shall employ Landlord to provide any cleaning and janitorial
services in excess of those specified in Schedule E and Tenant shall deliver to
Landlord a list setting forth in reasonable detail all such excess cleaning and
janitorial services.  Landlord, its cleaning contractor and their employees
shall have access to the Demised Premises at all times after 5:30 P.M. and
before 8:00 A.M. and shall have the right to use, without charge therefor, all
light, power and water in the Demised Premises reasonably required to clean the
Demised Premises as required under this Section 21.01.  Tenant shall comply with
any rules Landlord and/or its cleaning contractor and/or any consultant to
Landlord may establish regarding the management and recycling of solid waste, as
may be necessary for Landlord to comply with any Legal Requirements, including
without limitation the New Jersey Department of Environmental Protection Rules
on Coastal Resources and Development (N.J.A.C. 7:7E - 1.1).

               (e)  Furnish water for lavatory and drinking and office cleaning
purposes. If Tenant requires, uses or consumes water for any other purposes,
Tenant agrees that Landlord may install a meter or meters or other means to
measure Tenant's water consumption, and Tenant further agrees to reimburse
Landlord for the cost of the meter or meters and the installation thereof, and
to pay for the maintenance of said meter equipment and/or to pay Landlord's cost
of other means of measuring such water consumption by Tenant.  Tenant shall
reimburse Landlord for the cost of all water consumed in excess of that
estimated to be consumed for lavatory, drinking and office cleaning purposes, as
measured by said meter or meters or as otherwise measured, including sewer
rents.

               (f)  Maintain the common areas of the Complex in good order and
repair.

               (g)  Permit Tenant to use sufficient shaft space in Plaza III to

provided, that all work required for Tenant to use such shaftway shall be
subject to Landlord's prior approval and shall be performed at Tenant's expense
in accordance with this Article 6 and the other applicable provisions of this
Lease; provided, further, that Landlord makes no representation or warranty
whatsoever concerning the suitability of such shaft space for such use by Tenant
(Tenant hereby acknowledging that in order to obtain access to such shaft space
Tenant will require access to the premises of other tenants in Plaza III and
Tenant shall be solely responsible for negotiating for such right of access).

       21.02.  Landlord reserves the right without any liability whatsoever,
or abatement of Basic Annual Rent or additional rent, to stop the heating, air
conditioning, elevator, plumbing, electric and other systems when necessary by
reason of accident or emergency or for repairs, alterations, replacements or
improvements, provided that except in case of emergency, Landlord will notify
Tenant in advance, if possible, of any such stoppage and, if ascertainable, its
estimated duration, and will proceed diligently with the work necessary to
resume such service as 

                                      50

promptly as possible and in a manner so as to minimize interference with
Tenant's use and enjoyment of the Demised Premises, but Landlord shall not be
obligated to employ overtime or premium labor therefor.

          21.03.  It is expressly agreed that only Landlord or any one or more
persons, firms or corporations authorized in writing by Landlord (which
authorization shall be granted only if the employment of such person, firm or
corporation would not result in jurisdictional disputes or strikes or cause
disharmony with other workers or servicers employed at the Property or conflict
with the terms of any contract with such workers or servicers) will be permitted
to furnish laundry, drinking water, ice, food or beverages, cable television and
other similar supplies and services to tenants and licensees in the Building.
Landlord may fix, in its reasonable judgment, at any time and from time to time,
the hours during which and the regulations under which such supplies and
services are to be furnished.  Landlord expressly reserves the right to act as
or to designate, at any time and from time to time, an exclusive supplier of all
or any one or more of the said supplies and services, provided that the quality
thereof and the charges therefor are reasonably comparable to that of other
suppliers.  Landlord expressly reserves the right to exclude from the Building
any messenger service.  It is understood, however, that Tenant or regular office
employees or guests of Tenant who are not employed by any supplier of such food
or beverages or by any person, firm or corporation engaged in the business of
purveying such food or beverages, may on an occasional or incidental basis (i)
personally bring food or beverages into the Building for consumption within the
Demised Premises by employees or guests of Tenant, or (ii) order food or
beverages for delivery from take-out or catering establishments, provided that
such deliveries do not materially cause elevator delays nor inconvenience the
other tenants of the Building.  No food or beverage may be brought into the
Building for resale to or for consumption by any other tenant.

          21.04.  Landlord will not be required to furnish any other services,
except as otherwise provided in this Lease.

                                 SUBORDINATION

          25.01.  This Lease is and shall be subject and subordinate to all
ground or underlying leases which may now or hereafter affect the Land, the
Building or the Complex and to all mortgages which may now or hereafter affect
such leases, the Land, the Building or the Complex, and to all renewals,
refinancings, modifications, replacements and extensions thereof (hereinafter
called "Superior Instruments").  The provisions of this Section 25.01 shall be
selfoperative and no further instrument of subordination shall be required.  In
confirmation of such subordination, Tenant shall promptly execute and deliver at
its own cost and expense any instrument, in recordable form if required, that
Landlord, the holder of any Superior Instrument or any of their respective
successors in interest may request to evidence such subordination, within seven
(7) business days after such request.

          25.02.  In the event of a termination of any ground or underlying
lease, or if the interests of Landlord under this Lease are transferred by
reason of, or assigned in lieu of, foreclosure or other proceedings for
enforcement of any mortgage, or if the holder of any mortgage acquires a lease
in substitution therefor, then Tenant will, at the option to be exercised in
writing by the holder of any such Superior Instrument or any purchaser, assignee
or lessee, as 

                                      53
<PAGE>
 
the case may be, either (i) attorn to it and perform for its benefit all the
terms, covenants and conditions of this Lease on Tenant's part to be performed
with the same force and effect as if it were the landlord originally named in
this Lease, or (ii) enter into a new lease with it for the remaining term of
this Lease and otherwise on the same terms and conditions and with the same
options, if any, then remaining. The foregoing provisions of clause (i) of this
Section 25.02 shall inure to the benefit of such holder of a Superior
Instrument, purchaser, assignee or lessee, shall be self-operative upon the
exercise of such option, and no further instrument shall be required to give
effect to such option and to said provisions. Tenant, however, upon demand of
any such holder of a Superior Instrument, purchaser, assignee or lessee agrees
to execute, from time to time, within seven (7) business days after a request
therefor, instruments in confirmation of the foregoing provisions of this
Section 25.02, satisfactory to any such holder of a Superior Instrument,
purchaser, assignee or lessee, acknowledging such attainment and setting forth
the terms and conditions of its tenancy.

          25.03.  Notwithstanding anything contained herein to the contrary
under no circumstances shall any such holder of a Superior Instrument,
purchaser, assignee or lessee, as the case may be, whether or not it shall have
succeeded to the interests of the landlord under this Lease, be

                  (a)  liable for any act, omission or default of any prior
landlord; or

                  (b)  subject to any offsets, claims or defenses which Tenant
might have against any prior landlord; or

                  (c)  bound by any Basic Annual Rent or additional rent which
Tenant might have paid to any prior landlord for more than one month in advance
or for more than three months in advance where such rent payments are payable at
intervals of more than one month; or

                  (d)  bound by any modification, amendment or abridgment of the
Lease, or any cancellation or surrender of the same, made without its prior
written approval.

          25.04.  If, in connection with the financing of the Building or the
Complex, the holder of any mortgage shall request reasonable modifications in
this Lease as a condition of approval thereof, Tenant will not unreasonably
withhold, delay or defer making such modifications provided the same do not (i)
increase the Basic Annual Rent or additional rent payable by Tenant, (ii) reduce
the term hereof or (iii) extend the Term hereof other than as permitted in
Article 2 hereof.

          25.05.  Any holder of a Superior Instrument may at any time and from
time to time elect to have this Lease made prior to such Superior Instrument
and, upon notification of such election from such holder to Tenant, this Lease
shall have priority over such Superior Instrument, whether this Lease is dated,
executed, delivered and/or recorded prior or subsequent to the date such
Superior Instrument is dated, executed, delivered and/or recorded.

          25.06.  Tenant shall give each holder of a Superior Instrument a copy
of any notice of default served upon Landlord, provided that Tenant has been
notified of the address of 

                                      54
<PAGE>
 
such holder. If Landlord fails to cure any default as to which Tenant is
obligated to give notice pursuant to the preceding sentence within the time
provided for in this Lease, then each such holder shall have an additional
thirty (30) days after receipt of such notice within which to cure such default,
or if such default cannot be cured by such holder within that time (because such
holder must first obtain possession of the Demised Premises or other portions of
the Complex, or otherwise), then such additional time as may be necessary if,
within such 30 days, any such holder has commenced and is diligently pursuing
the remedies reasonably necessary to cure such default, in which event this
Lease shall not be terminated while such remedies are being so diligently
pursued.

                             CERTIFICATE OF TENANT

          26.01.  Tenant shall, without charge, at any time and from time to
time, within ten ( 10) days after request by Landlord, execute, acknowledge and
deliver to Landlord, the holder of a Superior Instrument or any other person,
firm or corporation specified by Landlord, a written instrument in the form
attached hereto as Schedule F or such other form as may be required by the
holder of any Superior Instrument.  If Tenant believes that any of the
certifications contained therein are inaccurate, said written instrument shall
set forth, in reasonable detail, the basis for Tenant's assertions that such
certifications are inaccurate.

          26.02.  Tenant agrees that, except for the first month's rent
hereunder, it will pay no rent under this Lease more than thirty (30) days in
advance of its due date, if so restricted by any existing or future Superior
Instrument or by an assignment of this Lease to the holder of such Superior
Instrument, and, in the event of any act or omission by Landlord which would
give Tenant the right to terminate this Lease, Tenant will not exercise such
right until Tenant shall have first given written notice of such act or omission
to the holder of any Superior Instrument who shall have furnished such holder's
last address to Tenant, and until a reasonable period for remedying such act or
omission shall have elapsed following the giving of such notices, during which
time such holder shall have the right, but shall not be obligated, to remedy or
cause to be remedied such act or omission.  Tenant further agrees not to
exercise any such right if the holder of any such Superior Instrument commences
to cure such act or omission within a reasonable time after having received
notice thereof and diligently prosecutes such cure thereafter.

          26.03.  Tenant shall, without charge, at any time and from time to
time, deliver to Landlord within ten (10) days after request therefor (a) copies
of the most current financial statements of Tenant and of any guarantor of
Tenant's obligations under this Lease certified by an independent certified
public accountant and (b) such further detailed financial information with
respect to Tenant and any such guarantors as Landlord or the holder of any
Superior Instrument may request.

                       LEGAL PROCEEDINGS, WAIVER OF JURY

                      TRIAL, WAIVER OF TERMINATION RIGHTS

          27.01.  Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties hereto against the
other on any matters whatsoever arising out of or in any way in connection with
this Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy
of the Demised Premises, and/or any other claims (except claims for personal
injury or property damage), and any emergency statutory or any other statutory
remedy.  It is further mutually agreed that in the event Landlord commences any
summary proceeding for non-payment of rent, Tenant will not interpose and does
hereby waive the right to interpose any counterclaim of whatever nature or
description in any such proceeding, unless Tenant receives an opinion from its
attorneys specifying the basis for the conclusion contained therein, that such
waiver will result in the waiver of its right to bring such claims in a separate
proceeding under applicable law.  Tenant waives all rights now or hereafter
conferred by law (including, without limitation, the benefit of New Jersey
Revised Statutes, Title 46, Chapter 8, Sections 6 and 7), (a) to quit, terminate
or surrender this Lease or the Demised Premises or any part thereof, or (b) to
any abatement, suspension, deferment or reduction of the Basic Annual Rent or
additional rent payable under this Lease, regardless of whether such rights
shall arise from any present or future constitution, statute or rule of law.

                                   ARTICLE 28

                             SURRENDER OF PREMISES

          28.01.  Upon the expiration or other termination of the Term, Tenant
shall quit and surrender to Landlord the Demised Premises, broom clean, in good
order and condition, ordinary wear and tear and damage by fire, the elements or
other casualty excepted, and Tenant shall remove all of its property as herein
provided.  Tenant's obligation to observe or perform this covenant shall survive
the expiration or other termination of the Term.

          28.02.  If Tenant shall, without the written consent of Landlord, hold
over after the expiration of the Term, such tenancy shall be deemed a month-to-
month tenancy, which tenancy may be terminated as provided by applicable law.
During such tenancy, Tenant agrees to (a) pay to Landlord, each month, the
greater of the fair market rental value for the Demised Premises or one hundred
and fifty percent (150%) during the first thirty days of holding over, one
hundred and seventy five percent ( 175%) during the next thirty days of holding
over and two hundred percent (200%) thereafter of (x) the Basic Annual Rent and
(y) all additional rent payable by Tenant for the last month of the Term and (b)
be bound by all of the terms, covenants and conditions herein specified.

                             RULES AND REGULATIONS

          29.01.  Tenant and Tenant's servants, employees and agents shall
observe faithfully and comply strictly with the Rules and Regulations set forth
in Schedule G hereto entitled "Rules and Regulations" and such other and further
reasonable Rules and Regulations as Landlord or Landlord's agents may from time
to time adopt; provided, however, that in case of any conflict or inconsistency
between the provisions of this Lease and of any of the Rules and Regulations, as
originally or as hereafter adopted, the provisions of this Lease shall control.
Reasonable written notice of any additional Rules and Regulations shall be given
to Tenant.

          29.02.  Nothing in this Lease contained shall be construed to impose
upon Landlord any duty or obligation to enforce the Rules and Regulations or the
terms, covenants or conditions in any other lease, against any other tenant of
the Complex, and Landlord shall not be liable to Tenant for violation of the
same by any other tenant, its servants, employees, agents, visitors or
licensees.

          29.03.  No Rule or Regulation shall be enforced against Tenant unless
such Rule or Regulation is being enforced against other tenants or occupants of
the Building under similar circumstances, if a similar rule or regulation is
contained in or promulgated pursuant to the leases and occupancy agreements
between Landlord and such tenants or occupants.

                             CONSENTS AND APPROVALS

          30.01.  (a)  Whenever Landlord's consent or approval is required in
this Lease, Landlord shall not unreasonably delay notifying Tenant whether its
approval shall be granted or withheld.

                  (b)  When in this Lease Landlord's consent or approval is
required and this Lease provides that Landlord's consent or approval shall not
be unreasonably withheld and Landlord shall refuse such consent or approval, or
in any instance in which Landlord shall delay its consent or approval, Tenant in
no event shall be entitled to make, nor shall Tenant make, any claim, and Tenant
hereby waives any claim, for money damages (nor shall Tenant claim any money
damages by way of set-off, counterclaim or defense) based upon any claim or
assertion by Tenant that Landlord unreasonably withheld or unreasonably delayed
its consent or approval. Tenant's sole remedy shall be an action or proceeding
to enforce any such provision, for specific performance, injunction or
declaratory judgment.

                  (c)  Whenever Landlord's consent or approval is required in
this Lease and this Lease does not provide that such approval or consent shall
not be unreasonably withheld, Landlord may determine in its sole discretion
whether to grant such consent or approval, regardless of whether such refusal to
consent or approve may be deemed arbitrary.

                                    NOTICES

          31.01.  Any notice or demand, consent, approval or disapproval, or
statement (collectively called "Notices") required or permitted to be given by
the terms and provisions of this Lease, or by any law or governmental
regulation, either by Landlord to Tenant or by Tenant to Landlord, shall be in
writing and unless otherwise required by such law or regulation, shall be
personally delivered or sent by United States mail postage prepaid as registered
or certified mail, return receipt requested. Any Notice shall be addressed to
Landlord or Tenant, as applicable, at its address set forth on page 1 of this
Lease as said address may be changed from time to time as hereinafter provided.
After Tenant shall occupy the Demised Premises, the address of Tenant for
Notices shall be the Building. By giving the other party at least ten (10) days
prior written notice, either party may, by Notice given as above provided,
designate a different address or addresses for Notices.

          31.02.  Any Notice shall be deemed given as of the date of delivery as
indicated by affidavit in case of personal delivery or by the return receipt in
the case of mailing; and in the event of failure to deliver by reason of changed
address of which no Notice was given or refusal to accept delivery, as of the
date of such failure as indicated by affidavit or on the return receipt or by
notice of the postal service, as the case may be.

          31.03.  In addition to the foregoing, either Landlord or Tenant may,
from time to time, request in writing that the other party serve a copy of any
Notice on one other person or entity designated in such request, such service to
be effected as provided in Section 31.01 hereof.

                                  ARTICLE 32

                                   NO WAIVER

          32.01.  No agreement to accept a surrender of this Lease shall be
valid unless such agreement is in writing and signed by Landlord.  No employee
of Landlord or of Landlord's agents shall have any power to accept the keys of
the Demised Premises prior to the termination of this Lease.  The delivery of
keys to any employee of Landlord or of Landlord's agent shall not operate as a
termination of this Lease or a surrender of the Demised Premises.  In the event
Tenant at any time desires to have Landlord sublet the premises for Tenant's
account, Landlord or Landlord's agents are authorized to receive said keys for
such purpose without releasing Tenant from any of the obligations under this
Lease.  The failure of Landlord or Tenant to seek redress for violation of, or
to insist upon the strict performance of, any covenant or condition of this
Lease or any of the Rules and Regulations set forth herein, or hereafter adopted
by Landlord, shall not prevent a subsequent act, which would have originally
constituted a violation, from having all the force and effect of an original
violation.  The receipt by Landlord, or the payment by Tenant, of rent with
knowledge of the breach of any covenant of this Lease shall not be deemed a
waiver of such breach.  The failure of Landlord to enforce any of the Rules and
Regulations set forth herein, or hereafter adopted, against Tenant and/or any
other tenant in the 

                                      58
<PAGE>
 
Complex shall not be deemed a waiver of any such Rules and Regulations. No
provision of this Lease shall be deemed to have been waived by Landlord or
Tenant unless such waiver be in writing signed by such party. No payment by
Tenant or receipt by Landlord of a lesser amount than the monthly rent herein
stipulated shall be deemed to be other than on the account of the earliest
stipulated rent, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment of rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such rent or pursue any other remedy
in this Lease provided.

          32.02.  This Lease, including all schedules and exhibits hereto
contains the entire agreement between the parties, and any executory agreement
hereafter made shall be ineffective to change, modify, discharge or effect an
abandonment of it in whole or in part unless such executory agreement is in
writing and signed by the party against whom enforcement of the change,

                                  ARTICLE 37

                                    PARKING

          37.01.  Landlord shall make 6 parking spaces ("Tenant's Parking
Spaces") available to Tenant and Tenant shall hire same from Landlord, in such
areas (the "Parking Areas") of the Property as Landlord shall periodically

Tenant's Parking Spaces will be under cover or open.  Tenant's Parking Spaces
shall be used exclusively for the parking of standard size passenger cars (or
smaller cars), or such other vehicles as may be otherwise permitted by Landlord
or the independent contractor conducting the parking operation at the Parking
Area, belonging to or leased to or operated by Tenant, any of Tenant's permitted
subtenants, and their respective employees, visitors and invitees, and for no
other purpose.  Tenant shall not allow any parking of any cars of Tenant or
Tenant's permitted subtenants, or their employees, visitors or invitees, outside
of the Parking Areas or in parking spaces within the Property designated for use
by Landlord or other tenants or their respective employees, visitors or
invitees.  Landlord reserves the right to relocate or alter Tenant's Parking
Spaces if, in Landlord's sole judgment, it becomes desirable to do so during the
Term.  Tenant 

                                      60

operated by Tenant and Tenant's permitted subtenants and their employees and
contractors.

          37.02.  All parking spaces used by Tenant, its employees, visitors and
invitees will be used at their own risk, and Landlord shall not be liable for
any injury to person or property, or for loss or damage to any automobile or its
contents, resulting from theft, collision, vandalism or any other cause
whatsoever, unless such injury or loss is caused by the negligence or willful
act of Landlord.

          37.03.  Landlord shall have the right to license an independent
operator or conduct a parking operation open to the public with respect to the
Parking Areas or to conduct such operation itself.

the first day of each month, without any set-off or deduction whatsoever, or in
lieu thereof, to any parking operator who shall be licensed by Landlord to

obtained by multiplying the number of Tenant's Parking Spaces by the monthly
rate then charged by Landlord or such operator to the general public for an
equivalent space for such month.  If Tenant's Parking Spaces shall be first made
available to Tenant other than on the first day of a month, then Tenant shall
make the payments in respect of such Spaces for such month on the date same are
so made available appropriately prorated.

          37.05.  Landlord, or the parking lot operator, as the case may be,
shall have the right to tow, at Tenant's sole cost and expense, any of Tenant's

parked in Tenant's Parking Spaces shall exhibit such identification as Landlord
may from time to time deem reasonably necessary to control the use of the
Parking Areas.  Landlord shall have the right to tow, at Tenant's sole cost and
expense, any of Tenant's or Tenant's permitted subtenants' or their employees',
visitors' or invitees', cars not exhibiting such identification if required.

          37.07.  Landlord shall have the right to institute valet parking, as a

                                   INDEMNITY

          Tenant shall indemnify, defend, pay on behalf of and hold harmless
Landlord and all holders of Superior Instruments, and its and their respective
partners, joint ventures, directors, officers, invitees, agents, servants and
employees (each an "indemnitee" for purposes of this provision), from and
against any loss, damage, liability, cost, claim or expense (including

                                      61
<PAGE>
 
reasonable attorneys' fees) arising from or in connection with (a) any act,
omission or negligence of Tenant or any subtenants, or its or their respective
partners, joint ventures, directors, officers, invitees, agents, servants and
employees, (b) any accident, injury or damage whatsoever occurring in the
Demised Premises, (c) the use or occupation of the Demised Premises by Tenant or
anyone claiming under or through Tenant or (d) any breach of this Lease by
Tenant. This provision shall not be construed to exculpate an indemnitee, or to
make Tenant responsible for, any loss, damage, liability, cost, claim or expense
resulting solely from or caused (whether by act or omission) solely by the gross
negligence or willful misconduct of such indemnitee.

                                  ARTICLE 39

                              MEMORANDUM OF LEASE

          39.01.  Tenant shall not record this Lease or a memorandum thereof.
Tenant shall, at the request of Landlord, execute and deliver to Landlord a
memorandum of lease in respect of this Lease sufficient for recording, but said
memorandum of this Lease shall not in any circumstances be deemed to modify or
to change any of the provisions of this Lease.

                                  ARTICLE 40

                                   SECURITY

          40.01.  Tenant has deposited with Landlord an unconditional
irrevocable letter of credit (as hereinafter defined) substantially in the form
attached hereto as Schedule H (as the same may be modified in accordance with
this section, the "letter of credit") in an amount equal to Two Hundred Forty
Thousand and 00/100 Dollars ($240,000), as security for the full and punctual
performance by Tenant of all of the terms of this Lease.  In the event Tenant
defaults in the performance of any of the terms of this Lease, Landlord may draw
upon the letter of credit in full and any amounts not applied as hereinafter
provided shall be held by Landlord subject to and in accordance with the
provisions of this Section.  Landlord may then apply the whole or any part of
the security so drawn upon to the extent required for the payment of (i) any
rent or (ii) any sum which Landlord may expend or may be required to expend by
reason of Tenant's default including, without limitation, any damages or
deficiency in the re-letting of the Demised Premises, whether accruing before or
after summary proceedings or other re-entry by Landlord. Upon each such
application, Tenant shall, on demand, pay to Landlord the sum so applied in cash
which shall be added to the remaining proceeds from the letter of credit so that
the security held by Landlord shall be restored to the amount first set forth
above.  If Tenant shall fully and punctually comply with all of the terms of
this Lease, the letter of credit or the amount of the security deposit, as the
case may be, shall be returned to Tenant after the termination of this Lease,
delivery of exclusive possession of the Demised Premises to Landlord and the
payment to Landlord of all amounts payable hereunder.  In the event of a sale or
lease of the Building, Landlord shall have the right to transfer the letter of
credit or the security deposit to the vendee or lessee and Landlord shall ipso
facto be released by Tenant from all liability for the return of such security;
and Tenant agrees to look solely to the new landlord for the return of said
security and it 

                                      62
<PAGE>
 
is agreed that the provisions hereof shall apply to every transfer or assignment
made of the letter of credit or security to a new landlord. If 30 days prior to
the date of such sale, Landlord shall be holding a letter of credit as Tenant's
security, Tenant will upon five (5) days prior written notice, deliver a
substitute letter of credit naming the new landlord as the new beneficiary
thereof. In the event Tenant shall default in such obligation, Landlord may draw
upon the letter of credit and transfer the proceeds thereof to the new landlord.
Tenant shall not assign or encumber or attempt to assign or encumber the monies
deposited herein as security and neither Landlord nor its successors or assigns
shall be bound by any such assignment, encumbrance, or attempted assignment or
encumbrance. In the event the letter of credit referred to above or any
substitute letter of credit is not renewed so that at all times the letter of
credit held by Landlord hereunder is valid for a period in excess of 30 days,
Landlord may draw upon said letter of credit and hold the proceeds thereof
subject to and in accordance with the terms of this Section.

          40.02.  So long as Tenant is not then in default under this Lease and
no monetary default or material non-monetary default under this Lease shall have
previously occurred, Tenant shall have the right, by notice (a "Reduction
Notice") given to Landlord at any time after each Reduction Date (as defined
below) to reduce the amount of security held by landlord pursuant to this
Article 40 by $24,000.00.  If Tenant properly gives a Reduction Notice to
Landlord, Landlord shall return such letter of credit to Tenant; provided, that
Tenant has delivered to Landlord a substitute letter of credit in an amount
equal to the difference between the amount of the letter of credit which
Landlord is returning to Tenant less $24,000.00.  Anything to the contrary
contained in this Section 40.02 notwithstanding, in no event shall the amount of
security held by Landlord pursuant to this Article 40 be less than $120,000.00.
"Reduction Date" means March 31, 1999, March 31, 2000, March 31, 2001, March 31,
2002 and March 31, 2003. Landlord agrees to reasonably cooperate with Tenant to
substitute any letter of credit in accordance with this Section 40.02; provided,
that such cooperation shall be without expense or liability to Landlord.  If at
any time Tenant shall be in monetary default or material non-monetary default
under this Lease, this Section 40.02 shall be null and void and of no further
force and effect and Tenant shall have no further right to reduce the amount of
security held by Landlord pursuant to the Article 40.

                                  ARTICLE 41

                                 MISCELLANEOUS

          41.01.  Irrespective of the place of execution or performance, this
Lease shall be governed by and construed in accordance with the laws of the
State of New Jersey.

          41.02.  This Lease shall be construed without regard to any
presumption or other rule requiring construction against the party causing this
Lease to be drafted.

          41.03.  Except as otherwise expressly provided in this Lease, each
covenant, agreement, obligation or other provision of this Lease on Tenant's
part to be performed shall be deemed and construed as a separate and independent
covenant of Tenant, not dependent on any other provision of this Lease.

                                      63
<PAGE>
 
          41.04.  All terms and words used in this Lease, regardless of the
number or gender in which they are used, shall be deemed to include any other
number and any other gender as the context may require.

          41.05.  Time shall be of the essence with respect to the exercise of
any option granted under this Lease.

          41.06.  Except as otherwise provided herein whenever payment of
interest is required by the terms hereof it shall be at the Interest Rate

          41.07.  If the Demised Premises or any additional space to be included
within the Demised Premises shall not be available for occupancy by Tenant on
the specific date herein before designated for the commencement of the term of
this Lease or for the inclusion of such space for any reason whatsoever, then
this Lease shall not be affected thereby but, in such case, said specific date
shall be deemed to be postponed until the date when the Demised Premises or such
additional space shall be available for occupancy by Tenant, and Tenant shall
not be entitled to possession of the Demised Premises or such additional space
until the same are available for occupancy by Tenant; provided, however, Tenant
shall have no claim against Landlord, and Landlord shall have no liability to
Tenant by reason of any such postponement of said specific date, and the parties
hereto further agree that any failure to have the Demised Premises or such
additional space available for occupancy by Tenant on said specific date or on
the Commencement Date shall in no wise affect the obligations of Tenant
hereunder nor shall the same be construed in any wise to extend the Term.

          41.08.  In the event that Tenant is in arrears in payment of Basic
Annual Rent or additional rent hereunder, Tenant waives Tenant's right, if any,
to designate the items against which any payments made by Tenant are to be
credited, and Tenant agrees that Landlord may apply any payments made by Tenant
to any items it sees fit, irrespective of and notwithstanding any designation or
request by Tenant as to the items against which any such payments shall be
credited.

          41.09.  All Schedules and Exhibits referred to in this Lease are
hereby incorporated in this Lease by reference.

          41.10.  The covenants, conditions and agreements contained in this
Lease shall bind and inure to the benefit of Landlord and Tenant and their
respective heirs, distributees, executors, administrators, successors, and
except as otherwise provided in this Lease, their assigns.

          41.11.  Tenant hereby acknowledges that in order to avoid delay, this
Lease has been prepared and submitted to Tenant for signature with the
understanding that it shall not be deemed an offer by Landlord or bind Landlord
unless and until it is executed and delivered by Landlord.

<PAGE>
 
          41.12.  The exterior walls of the Building, the portions of any window
sills outside the windows and the windows are not part of the premises demised
by this Lease and Landlord reserves all rights to such parts of the Building.

          41.13.  INTENTIONALLY DELETED

          41.14.  Upon the expiration or sooner termination of this Lease or
upon the closure of Tenant's operations in the Demised Premises or upon the sale
or other disposition of all or any part of the Building or land thereunder by
Landlord, Tenant shall, at its sole cost and expense, comply with all applicable
provisions of all Legal Requirements relating to environmental laws and
regulations, including, without limitation, the New Jersey Industrial Site
Recovery Act (and all amendments and successors thereto) (including, without
limitation, obtaining a letter of non-applicability within three months after
the Expiration Date confirming that Tenant is not an industrial establishment)
with respect to the Demised Premises and any other portion of the Property
affected by Tenant's operations.  Notwithstanding the foregoing, Tenant shall
not be liable for any such compliance relating to environmental matters, whereby
such compliance is required as a direct result of any act or omission relating
to the Demised Premises, which took place prior to the Commencement Date.
Tenant shall indemnify and hold harmless Landlord and any holder of a Superior
Instrument, and its and their respective partners, joint venturers, directors,
officers, agents, servants and employees from and against any loss, damage,
liability, cost, claim or expense (including reasonable attorneys' fees) arising
from or in connection with Tenant's failure to so comply with all such
provisions.

          41.15.  This Lease constitutes the entire agreement of the parties
with respect to the matters hereof, and may not be modified except by a written
instrument executed by Landlord and Tenant.

                                  ARTICLE 42

                             INTENTIONALLY OMITTED


                                  ARTICLE 43

                                  ARBITRATION

          43.01.  Landlord may at any time request arbitration, and Tenant may
at any time when not in default in the payment of any Basic Annual Rent or
additional rent request arbitration, of any matter in dispute with respect to
which arbitration is expressly provided for in this Lease.  The party requesting
arbitration shall do so by giving notice to that effect to the other party
specifying the nature of the dispute.  Said dispute shall be determined in
Newark, New Jersey, by a single arbitrator, in accordance with the rules then
obtaining of the American Arbitration Association (or any organization which is
the successor thereto).  The award in such arbitration may be enforced on the
application of either party by the order or judgment of a court of competent
jurisdiction.  The fees and expenses of any arbitration shall be borne by the
parties 

                                      65
<PAGE>
 
equally, but each party shall bear the expense of its own attorneys and experts
and the additional expenses of presenting its own proof.

                                  ARTICLE 44

                                OPTION TO RENEW

          44.01.  (a)  Provided that (i) the PR Newswire Tenant (as defined
below) renews or extends the PR Newswire Lease (as defined below) beyond March
31, 2007 and (ii) both when it exercises the option to extend described below
and when the Extended Term (as defined below) commences (a) this Lease is in
full force and effect and (b) the party executing this Lease occupies at least
90% of the Demised Premises, Tenant shall have the option to extend the term of
this Lease for an additional term which is coterminous with the term for which
the PR Newswire Tenant renews or extends the PR Newswire Lease (the "Extended
Term").  If the PR Newswire Tenant renews or extends the PR Newswire Lease
beyond March 31, 2007, Landlord shall notify Tenant thereof (the "PR Extension
Notice").  If the PR Newswire Lease is terminated prior to the termination date
provided for in the PR Newswire Lease, Landlord shall notify Tenant thereof.
Such option to extend the term of this Lease may be exercised only by Tenant
giving written notice to Landlord on or before the date that is sixty (60) days
after Landlord gives the PR Extension Notice to Tenant.  It is expressly agreed
that Tenant shall not have an option to extend the term of this Lease beyond the
expiration of the Extended Term.  If this Lease shall be terminated before the
commencement of the Extended Term, Tenant's option to extend the term of this
Lease, or its exercise thereof, or the Extended Term or lease created by any
such exercise, shall be abrogated and rendered null and void.  If Tenant fails
to timely give such notice, Tenant's option to extend this Lease shall be
terminated and be deemed waived by Tenant.  The "PR Newswire Tenant" means PR
Newswire Association, Inc. and its successors and assigns under that certain
lease dated April 9, 1982, as amended, pursuant to which PR Newswire
Association, Inc. leases certain space on the 8th floor of Plaza III (the "PR
Newswire Lease").

                  (b)  Upon Tenant's giving notice of its election to extend the
term of this Lease for the Extended Term, pursuant to paragraph (a) above, this
Lease shall be deemed automatically amended as of the date following the
Expiration Date as follows: (i) the Basic Annual Rent shall be the greater of
(x) the Basic Annual Rent payable under this Lease immediately prior to the
original Expiration Date or (y) the fair market rent for the Demised Premises
for the Extended Term as determined pursuant to Section 44.02; and (ii) the
Expiration Date of the Extended Term shall be the last day of the term for which
the PR Newswire Tenant renews or extends the PR Newswire Lease. Tenant and
Landlord shall promptly execute and deliver an appropriate modification of this
Lease to evidence said amendment.

          44.02.  (a)  For purposes of this Article 44, in such instances that
it is provided that Tenant shall pay a "fair market rent" as Basic Annual Rent,
such fair market rent shall be proposed by Landlord giving notice therefor (a
"FMR Notice"), not later than the later of (i) January 1, 2007 and (ii) thirty
(30) days after Tenant exercises the option to extend the term of this Lease
pursuant to this Article 44.

                                      66
<PAGE>
 
                  (b)  Within thirty (30) days after Landlord gives a FMR
Notice, Tenant shall notify Landlord as to whether or not it agrees with
Landlord's proposed fair market rent, and if it does not so agree, Tenant shall
in such notice submit to Landlord its proposed fair market rent. If Tenant fails
to respond as aforesaid within said 30 day period, Tenant hereby agrees that it
shall be deemed conclusively to have agreed to the fair market rent proposed by
Landlord.

                  (c)  If Landlord and Tenant do not agree upon the fair market
rent, the matter shall be submitted to arbitration in accordance with the
provisions of Article 43 hereof, subject, however, to the following
modifications

          (i)  the arbitrator selected shall have at least five years'
          experience in the leasing or management of office space in the
          northern New Jersey office market. The fees and expenses of the
          arbitrator and all other expenses (not including the attorneys' fees,
          witness fees and similar expenses of the parties which shall be borne
          separately by each of the parties) of the arbitration shall be borne
          equally by the parties hereto;

          (ii)  within two business days after the appointment of the
          arbitrator, there shall be submitted to the arbitrator the FMR Notice
          containing Landlord's proposed fair market rent and a copy of Tenant's
          response thereto containing Tenant's proposed fair market rent;

          (iii) within ten (10) business days thereafter, the arbitrator shall
          select either the fair market rent proposed by Landlord or Tenant,
          whichever the arbitrator determines is closest to his determination of
          the fair market rent for the Demised Premises.

          (iv)  in rendering such decision, the arbitrator shall determine the
          fair market rent that would be agreed upon by Landlord and a new
          unrelated third party tenant, and in connection therewith shall assume
          all of the following: (A) the Landlord and prospective tenant are
          typically motivated; (B) the Landlord and prospective tenant are well
          informed and well advised and each is acting in what it considers its
          own best interest; (C) a reasonable time under then-existing market
          conditions is allowed for exposure of the Demised Premises on the open
          market; (D) the rent is unaffected by concessions, special financing
          amounts and/or terms, or unusual services, fees, costs or credits in
          connection with the leasing transaction; (E) the Demised Premises are
          fit for immediate occupancy and use "as-is" and require no additional
          work by Landlord and that no work has been carried out thereon by the
          Tenant, its subtenant, or their predecessors in interest during the
          term which has diminished the rental value of the Demised Premises;
          (F) in the event the Demised Premises have been destroyed or damaged
          by fire or other casualty, they have been fully restored; (G) that the
          demised premises are to be let with vacant possession and subject to
          the provisions of this Lease for a term equal to the Extensino Term;
          (H) market rents then being charged for comparable space in other
          similar office buildings in the same area; (I) the computation of the
          number of rentable square feet contained in the Demised Premises shall
          be based on the 

                                      67
<PAGE>
 
          standard of measurement for such square footage then obtaining in the
          Building but in no event less than the square footage specified in
          Section 1.01(b); (J) the Base Tax Year and the Base Operating Year
          shall be as stated herein and (K) a full brokerage commission shall be
          payable by Landlord, on then market terms. In rendering such decision
          and award, the arbitrator shall not modify the provisions of this
          Lease.

          (v)  the decision and award of the arbitrator shall be in writing and
          be final and conclusive on all parties and counterpart copies thereof
          shall be delivered to each of said parties.  Judgment may be had on
          the decision and award of the arbitrator so rendered in any court of
          competent jurisdiction.

                  (d)  In the event that any payment of Basic Annual Rent is due
hereunder prior to the determination of the arbitrator Tenant shall pay as the
Basic Annual Rent it is obligated to pay under this Lease the amount set forth
in the FMR Notice.  If the arbitrator determines that the Basic Annual Rent
payable pursuant to this Article 44 is less than that set forth in the FMR
Notice, then Tenant shall be entitled to a credit in the amount of its
overpayment for such period against subsequent payments of Basic Annual Rent or
additional rent due hereunder.

                  (e)  Nothing contained in this Section 44.02 shall be deemed
in any way to alter or modify the provisions of Article 3 hereof.

          44.03.  If the PR Newswire Tenant does not renew the PR Newswire Lease
beyond March 31, 2007 and Landlord fails to notify Tenant thereof (the "PR Non-
Extension Notice") at least 180 days prior to the Expiration Date (unless Tenant
otherwise knew that the PR Newswire Tenant did not renew or extend the PR
Newswire Lease), then the Expiration Date shall be automatically extended for an
extension period commencing on the day after the originally scheduled Expiration
Date and ending on the date that is the earliest to occur of (i) the date that
is 180 days after Landlord gives the PR Non-Extension Notice to Tenant, (ii) the
date that is 180 days after Tenant first knew that the PR Newswire Tenant did
not renew or extend the PR Newswire Lease and (iii) the date that is 180 days
after the originally scheduled Expiration Date and such extension period shall
be upon all of the terms and conditions of this Lease existing prior to the
originally scheduled Expiration Date, except that Tenant shall have no right to
extend the term of this Lease beyond such extension period.

offer is subordinate to any right of offer, refusal right, extension right or

Notice") thereof, specifying (a) the fixed annual rental ("Offer Rental") which
Landlord is then considering for the lease of the Offer Space, (b) the proposed
term of the lease for such Offer Space and (c) such other matters as Landlord

                  (d)  If Tenant timely delivers the Acceptance Notice, then,
effective as of April 1, 2007 (the "Offer Space Inclusion Date"), Tenant shall 
                                    --------------------------

                  (e)  If Tenant fails to give an Acceptance Notice within the
period provided in paragraph (c) above, time of the essence, then (i) Landlord
may enter into one or more leases of the Offer Space with third parties on such
terms and conditions as Landlord shall determine, the Offer Space Option under
this Section 45.01 and the Offer Space Option under Section 45.02 shall be null
and void and of no further force and effect and Landlord shall have no further
obligation to offer the Offer Space to Tenant, and (ii) Tenant shall, upon
demand by Landlord, execute an instrument confirming Tenant's waiver of, and
extinguishing, the Offer Space Option under this Section 45.01 and the Offer
Space Option under Section 45.02, but the failure by Tenant to execute any such

Inclusion Date, Landlord and Tenant shall confirm the occurrence thereof and
Tenant's leasing of the Offer Space by executing an instrument reasonably
satisfactory to Landlord and Tenant; provided, that failure by Landlord or
Tenant to execute such instrument shall not affect Tenant's leasing of the Offer
Space in accordance with this Article.

                  (g)  If Landlord is unable to deliver possession of any
portion of the PR Newswire Space to Tenant for any reason on or before April 1,
2007, the Offer Space Inclusion Date with respect to any such portion shall be
the date on which Landlord is able to so deliver possession and Landlord shall
have no liability to Tenant therefor and this Lease shall not in any way be
impaired. This Section 45.01(g) constitutes "an express provision to the
contrary" within the meaning of Section 223(a) of the New York Real Property Law
and any other law of like import now or hereafter in effect.

                  (h)  Anything in this Lease to the contrary notwithstanding,
this Article 45 shall be null and void and of no force or effect if Exodus
Communications is no longer the Tenant under this Lease.

          45.02   Offer Space Option. (a) As used herein:

          "Available" as used in this Section 45.02 means that the PR Newswire
Space is free of any present or future possessory right now existing in favor of
any third party.  Tenant's right of first offer is subordinate to any right of
offer, refusal right, extension right or similar right or option in favor of any
third party existing as of the date of this Lease.

          "Offer Period" means the period commencing on the Commencement Date to
and including March 30, 2007.

          "Offer Space" as used in this Section 45.02 means the PR Newswire
Space.

                  (b)  Provided (i) the PR Newswire Tenant shall not have
renewed or extended the PR Newswire Lease beyond March 31, 2007, (ii) this Lease
shall not have been terminated and (iii) Tenant shall not be in default under
this Lease, if the Offer Space becomes, or Landlord reasonably anticipates that
within the next 12 months (but not later than the last day of the Offer Period),

("Offer Rental") which Landlord is then considering for the lease of the Offer
Space, (b) the date or estimated date that the Offer Space has or shall become
Available and (c) such other matters as Landlord may deem appropriate for such

Space Option under this Section 45.02 and on the Offer Space Inclusion Date (i)
this Lease shall not have been terminated and (ii) Tenant shall not be in
default under this Lease, Tenant shall have the option (the "Offer Space
Option"), exercisable by notice (an "Acceptance Notice") given to Landlord on or
before the date that is 30 days after the giving of the Offer Notice (time being
of the essence) to include all (but not less than all) of the Offer Space in the
Premises.

                  (d)  If Tenant timely delivers the Acceptance Notice, then, on
the date on which Landlord delivers vacant possession of the Offer Space to
Tenant, (the "Offer Space Inclusion Date"), the Offer Space shall become part of
the Premises upon all of the terms and conditions set forth in this Lease,
except (i) Basic Annual Rent with respect to the Offer Space shall be the Offer
Rental, (ii) Tenant's Tax Share and Tenant's Expense Share shall be
proportionately increased to reflect the additional rentable square feet of the

                  (f)  Promptly after the occurrence of the Offer Space
Inclusion Date, Landlord and Tenant shall confirm the occurrence thereof and the
inclusion of the Offer Space in the Premises by executing an instrument
reasonably satisfactory to Landlord and Tenant; provided, that failure by
Landlord or Tenant to execute such instrument shall not affect the inclusion of

                                  ARTICLE 46

                                ROOF EQUIPMENT

          46.01.  Subject to Landlord's prior approval, not to be unreasonably
withheld or delayed, Tenant shall have the right, subject to and in accordance
with the provisions of this Article 46, to use a portion of the roof of Plaza
III as designated on Exhibit J attached hereto and made a part hereof consisting
of approximately 20' x 28' to install, maintain and operate, at its sole cost
and expense, a back-up generator and day tank (the "Roof Equipment").  Tenant
shall furnish detailed plans and specifications for the Roof Equipment (or any
modification thereof) to Landlord for its approval.  Tenant's use of the rooftop
of Plaza III shall be a non-exclusive use and Landlord may permit the use of any
other portion of the roof to any other person for any use including without
limitation installation of communication equipment or other generators or tanks.
Tenant shall use its reasonable efforts to insure that its use of the rooftop
does not impair such other person's data transmission and reception via its
respective communication equipment. If Tenant's construction, installation,
maintenance, repair, operation or use of the Roof Equipment shall interfere with
the rights of Landlord (including, without limitation, Landlord's right to use
the remainder of the roof) or other tenants in the Building, Tenant shall
cooperate with Landlord or such other tenants in eliminating such interference;
provided, however, the cost of remedying such interference shall be borne by the
party which is suffering such interference, unless such party was using the
affected equipment prior to the use of the Roof Equipment by Tenant, in which
case the cost of remedying such interference shall be borne by Tenant.  Tenant
shall secure and keep in full force and effect, from and after the time Tenant
begins construction and installation of the Roof Equipment, such supplementary
insurance with respect to the Roof Equipment as Landlord may reasonably require.
Tenant shall pay any additional or increased insurance premiums incurred by
Landlord with respect to the Roof Equipment.

          46.02.  In connection with the installation, maintenance and operation
of the Roof Equipment, Tenant, at Tenant's sole cost and expense, shall comply
with all Legal Requirements, including, without limitation, any requirement to
install screening surrounding such installations, and shall procure, maintain
and pay for all permits required therefor, and Landlord makes no warranties
whatsoever as to the permissibility of Roof Equipment under applicable Legal
Requirements or the suitability of the roof of Plaza III for the installation
thereof.  If Landlord's structural engineer deems it advisable that there be
structural reinforcement of the roof in connection with the installation of the
Roof Equipment Landlord shall perform same at Tenants' cost and expense and
Tenant shall not perform any such installation prior to the completion of any
such structural reinforcement.  The installation of the Roof Equipment shall be
subject to the 

                                      72
<PAGE>
 
provisions of Article 6 applicable to alterations and installations. For the
purpose of installing, servicing or repairing the Roof Equipment, Tenant shall
have access to the rooftop of Plaza III at reasonable times upon reasonable
notice to Landlord and Landlord shall have the right to require, as a condition
to such access, that Tenant (or its employee, contractor or other
representative) at all times be accompanied by a representative of Landlord,
whom Landlord agrees to make available upon reasonable notice. Landlord agrees
to use reasonable efforts to cooperate with Tenant in order to grant Tenant
access to the rooftop in the event of an emergency. Tenant shall pay for all
electrical service required for Tenant's use of the Roof Equipment, to be
measured and charged in accordance with the provisions set forth in Article 4
hereof.

          46.03.  Tenant, at its sole cost and expense, shall promptly repair
any and all damage to the rooftop or to any other part of the Building caused by
the installation, maintenance, repair, operation or removal of the Roof
Equipment.  Tenant shall be responsible for all costs and expenses for repairs
and maintenance of the roof which result from Tenant's use of the roof for the
construction, installation, maintenance, repair, operation and use of the Roof
Equipment.  All installations made by Tenant on the rooftop or in any other part
of the Building pursuant to the provisions of this Article 46 shall be at the
sole risk of Tenant, and neither Landlord, nor any agent or employee of
Landlord, shall be responsible or liable for any injury or damage to, or arising
out of, the Roof Equipment.  Tenant's indemnity under Section 38.01 shall apply
with respect to the installation, maintenance, operation, repair, presence or
removal of the Roof Equipment.

          46.04.  Upon the expiration of the Term, the Roof Equipment shall be
removed by Tenant at its sole cost and expense, and Tenant shall repair any
damage to and restore the rooftop or any other portions of the Building to their
condition existing immediately prior to Tenant's installation of the Roof
Equipment.

          46.05.  Tenant shall not be required to pay rent for the use of such
Roof Equipment or use of the rooftop or any shaft space in connection with the
use of rooftop for the purposes permitted herein and none of the same shall be
included in the calculation of Tenant's Tax Share or Tenant's Expense Share.

          46.06.  Notwithstanding anything to the contrary contained in this
Article 46, Landlord shall have the right, at Landlord's expense, on not less
than thirty (30) days' prior notice, to relocate the Roof Equipment to another
location on the roof of the Building, and Tenant shall cooperate in all
reasonable respects with Landlord in any such relocation; provided, that if such
relocation is done pursuant to any Legal Requirement, the cost thereof charged
at Landlord's actual cost shall be borne by Tenant.

          46.07.  The rights granted in this Article 46 are given in connection
with, and as part of the rights created under, this Lease and are not separately
transferable or assignable but shall inure to and benefit Tenant and its
permitted successors and assigns.

          46.08.  If the installation of the Roof Equipment or act or omission
relating thereto should revoke, negate or in an any manner impair or limit any
roof warranty or guaranty obtained by Landlord, then Tenant shall reimburse
Landlord for any loss or damage sustained or costs or 

                                      73
<PAGE>
 
expenses incurred by Landlord as a result of such impairment or limitation,
provided Landlord shall use reasonable efforts to give Tenant reasonable notice
of any anticipated impairment and the opportunity to take any action necessary
to avoid or eliminate such impairment..

     1.   The rights of tenants in the entrances, corridors, elevators and
escalators of the Building are limited to ingress to and egress from the

and no tenant shall use, or permit the use of, the entrances, corridors,
escalators or elevators for any other purpose.  No tenant shall invite to the
tenant's premises, or permit the visit of, persons in such numbers or under such
conditions as to interfere with the use and enjoyment of any of the plazas,
entrances, corridors, escalators, elevators, Common Areas and other facilities
of the Property by other tenants.  Fire exits and stairways are for emergency
use only, and they shall not be used for any other purposes by the tenants,
their employees, licensees or invitees.  No tenant shall encumber or obstruct,
or permit the encumbrance or obstruction of any of the sidewalks, plazas,
entrances, corridors, escalators, elevators, Common Areas, fire exits or
stairways of the Property.  Landlord reserves the right to control and operate
the Common Areas in such manner as it deems best for the benefit of the tenants
generally.

     2.   The cost of repairing any damage to the Common Areas or to any

persons admitted to or leaving the Building outside of ordinary business hours
to register.  Tenant's employees, agents and visitors shall be permitted to
enter and leave the Building whenever appropriate arrangements have been
previously made between Landlord and Tenant with respect thereto.  Each tenant
shall be responsible for all persons for whom he requests such permission and
shall be liable to the Landlord for all acts of such persons.  Any person whose
presence in the Building at any time shall, in the judgment of Landlord, be

In case of invasion, riot, public excitement or other commotion Landlord may
prevent all access to the Building during the continuance of the same, by
closing the doors or otherwise, for the safety of the tenants and protection of
property in the Building.  Landlord may require any person leaving the Building
with any package or other object to exhibit a pass from the tenant from whose
premises the package or object is being removed, but the establishment and
enforcement of such requirements shall not impose any responsibility on Landlord
for the protection of any tenant against the removal of property from the
premises of the tenant.  Landlord shall, in no way, be liable to any tenant for
damages or loss arising from the admission, exclusion or ejection of any person
to or from the tenant's premises or the Building under the provisions of this

               -------------------                                             
additional rent, Tenant shall pay to Landlord, subject to adjustments and
reconciliation as provided in paragraph 16 of this lease, the sum of Nine
Thousand Five Hundred Thirty-Three and 83/100 Dollars ($9,533.83) on or before
the first day of the first full calendar month of the term and on the first day
of each and every successive calendar month, said sum representing Tenant's
estimated payment of its percentage share of common area charges as provided for
in paragraph 16 of this lease.  Payment of common area charges for any partial
month shall be payable in advance and shall be prorated based on the actual
number of days during the lease term occurring in such month divided by the
total number of days in such month.

          (c)  Manner and Place of Payment.  All payments of basic rent and
               ---------------------------                                 
common area charges shall be paid to Landlord, without deduction or offset, in
lawful money of the United States of America, at the office of Landlord at 3945
Freedom Circle, Suite 640, Santa Clara, California 95054, or to such other
person or place as Landlord may from time to time designate in writing.

          (d)  First Month's Rent.  Concurrently with Tenant's execution of this
               ------------------                                               
lease, Tenant shall deposit with Landlord the sum of Seventy-One Thousand One
Hundred Forty-Eight Dollars ($71,148.00) to be applied against the basic rent
for the first lease month of the term.

          (e)  Security Deposit.  Concurrently with Tenant's execution of this
               ----------------                                               
lease, Tenant shall deposit with Landlord the sum of Seventy-Eight Thousand Two
Hundred Sixty-Two and 80/100 Dollars ($78,262 82), which sum shall be held by
Landlord as a security deposit for the faithful performance by Tenant of all of
the terms, covenants and conditions of this lease to be kept and performed by
Tenant.  If Tenant defaults with respect to any provision of this lease,
including but not limited to, the provisions relating to the payment of basic
rent and common area charges, Landlord may (but shall not be required to) use,
apply, or retain all or any part of this security deposit for the payment of any
amount which Landlord may spend by

                                       2
<PAGE>
 
reason of Tenant's default or to compensate Landlord for any other loss or
damage which Landlord may suffer by reason of default.  If any portion of said
deposit is so used, Tenant shall, within ten (10) days after written demand
therefor, deposit cash with Landlord in the amount sufficient to restore the
security deposit to its original amount; Tenant's failure to do so shall be a
material breach of this lease.  Landlord shall not be required to keep this
security deposit separate from its general funds and Tenant shall not be
entitled to interest on such deposit.  If Tenant is not in default at the
expiration or termination of this lease, the security deposit or any balance
thereof shall be returned to Tenant within fifteen (15) days after Tenant has
vacated the Premises.  In the event of termination of Landlord's interest in
this lease, Landlord shall transfer said deposit to Landlord's successor in
interest, and Tenant agrees that Landlord shall thereupon be released from
liability for the return of such deposit or any accounting therefor; provided
Landlord's successor assumes the obligations of the Landlord under this lease.


     In addition to the above cash security deposit, Tenant shall deliver to
Landlord within ten (10) days following Tenant's execution of this lease an
unconditional irrevocable letter of credit in the amount of Three Hundred
Thousand Dollars ($300,000.00) in favor of Landlord to secure the faithful
performance by Tenant of all of the terms, covenants and conditions of this
lease to be kept and performed by Tenant.  Said letter of credit shall be
available by draft at sight, subject only to receipt by the bank of a notarized
statement from Birk S. McCandless or Steven E. Sund stating the amount demanded
as due and owing to Landlord, and shall otherwise be in a form reasonably
satisfactory to Landlord and Landlord's attorney and drawn upon such bank as
Landlord may approve. Said letter of credit shall by its terms expire not less
than one ( 1 ) year from the date issued, provided that unless Tenant deposits
with Landlord a cash security deposit of like amount, the letter of credit shall
be renewed for an additional period of not less than one (1) year. The amount of
the letter of credit shall be reduced by $60,000 at the end of each lease year,
such that the amount of the letter of credit during the term of the lease shall
be as follows:

<TABLE> 
          <S>                           <C> 
          Year 1                        $  300,000                         
          Year 2                        $  240,000                         
          Year 3                        $  180,000                         
          Year 4                        $  120,000                         
          Year 5                        $   60,000                          
</TABLE>

The bank's written renewal of the letter of credit shall be delivered to
Landlord not less than sixty (60) days prior to the expiration of such letter of
credit. If Landlord does not receive such written renewal at least sixty (60)
days prior to the expiration date of the letter of credit, then Landlord shall
be entitled to make demand for the principal amount of said letter of credit
and, thereafter, hold such funds in accordance with the first paragraph of this
paragraph 4(e). Tenant's failure to so deliver, renew (including specifically
but not limited to the delivery to Landlord of such renewal not less than sixty
(60) days prior to expiration of the letter of credit) and maintain such letter
of credit shall be a material breach of this lease.

                                       3
<PAGE>
 
     If Tenant defaults in the performance of any provision of this lease to be
performed by Tenant, including without limitation the timely payment of basic
rent and direct expenses and other amounts due Landlord, Landlord may
immediately and without further notice resort to said letter of credit (or the
funds received therefrom) and use or apply all or any part of same to compensate
Landlord for any loss or expense occasioned thereby and for the payment of any
amount due Landlord under the terms of this lease.  If any portion of said
letter of credit (or the funds received therefrom) is so used as specified
above, Tenant shall, within ten (10) days after written demand therefor, restore
the letter of credit (or the funds received therefrom) to its original amount,
and Tenant's failure to do so shall be a material breach of this lease.

     Landlord's resort to said letter of credit (or use of the funds received
therefrom) shall in no way or manner constitute an acceptance of or waiver of
such default by Tenant; nor shall such resort or use terminate, or permit Tenant
to terminate, or constitute a forfeiture of, or be construed as an election by
Landlord to terminate, this lease; nor shall such resort or use affect
Landlord's remedies otherwise available under this lease or at law.

     5.  ADJUSTMENT OF BASIC RENT

         The basic rent provided for in paragraph 4(a) shall be adjusted
periodically and the monthly basic rent for each period shall be as set forth
below:

<TABLE>
          <S>                           <C>  
          Lease Months 1-12             $  71,148.00 per month
          Lease Months 13-24            $  73,519.60 per month
          Lease Months 25-36            $  75,891.20 per month
          Lease Months 37-48            $  78,262.80 per month
          Lease Months 49-60            $  80,634.40 per month 
</TABLE>

     6.   RESTRICTION ON USE

          Tenant shall not do or permit to be done in or about the Premises or
the Project, nor bring or keep or permit to be brought or kept in or about the
Premises or Project, anything which is prohibited by or will in any way increase
the existing rate of, or otherwise affect, fire or any other insurance covering
the Project or any part thereof, or any of its contents, or will cause a
cancellation of any insurance covering the Project or any part thereof, or any
of its contents.  Tenant shall not do or permit to be done anything in or about
the Premises or the Project which will constitute waste or which will in any way
obstruct or interfere with the rights of other tenants or occupants of the
Project or injure or annoy them, or use or allow the Premises to be used for any
unlawful purpose, nor shall Tenant cause, maintain or permit any nuisance in or
about the Premises or the Project.  No loudspeaker or other device, system or
apparatus which can be heard outside the Premises shall be used in or at the
Premises without the prior written consent of Landlord.  Tenant shall not use
the Premises in any manner that will cause or emit any objectionable odor, noise
or light into the adjoining premises or Common Area.  Tenant shall not do
anything on the Premises that will cause damage to the Project and Tenant shall
not overload the floor capacity of the Premises or the Project.  No machinery,
apparatus or other appliance shall be used or operated in or on the Premises
that will in any manner injure, vibrate or shake the Premises.  Landlord shall
be the sole judge, of whether such odor, noise, light or

                                       4
<PAGE>
 
vibration is such as to violate the provisions of this paragraph.  No waste
materials or refuse shall be dumped upon or permitted to remain upon any part of
the Premises or the Project except in trash containers placed inside exterior
enclosures designated for that purpose by Landlord, or where otherwise
designated by Landlord; and no toxic or hazardous materials shall be disposed of
through the plumbing or sewage system.  No materials, supplies, equipment,
finished products or semi-finished products, raw materials or articles of any
nature shall be stored or permitted to remain outside of the building proper.
No retail sales shall be made on the Premises.  Tenant shall comply with any
covenant, condition or restriction ("C.C. & R.s") affecting the Premises upon
notice thereof to Tenant.

     7.  COMPLIANCE WITH LAWS

         Tenant shall, in connection with its use and occupation of the
Premises, at its sole cost and expense, promptly observe and comply with (i) all
laws, statutes, ordinances and governmental rules, regulations and requirements
of federal, state, county, municipal and other governmental authorities, now or
hereafter in effect, which shall impose any duty upon Landlord or Tenant with
respect to the use, occupancy or alteration to the Premises, (ii) with the
requirements of any board of fire underwriters or other similar body now or
hereafter constituted and (iii) with any direction or occupancy certificate
issued pursuant to law by any public authority; provided, however, that no such
failure shall be deemed a breach of these provisions if Tenant, immediately upon
notification, commences to remedy or rectify said failure. The judgment of any
court of competent jurisdiction or the admission of Tenant in any action against
Tenant (whether or not Landlord is a party thereto) that Tenant has violated any
such law, statute, ordinance or governmental rule, regulation, requirement,
direction or provision, shall be conclusive of that fact as between Landlord and
Tenant. This lease shall remain in full force and effect notwithstanding any
loss of use or other effect on Tenant's enjoyment of the Premises by reason of
any governmental laws, statutes, ordinances, rules, regulations and requirements
now or hereafter in effect.

     8.  ALTERATIONS

         Tenant shall not make or suffer to be made any alteration, addition or
improvement to or of the Premises or any part thereof (collectively referred to
herein as "alterations") without (i) the prior written consent of Landlord, (ii)
a valid building permit issued by the appropriate governmental authority and
(iii) otherwise complying with all applicable laws, regulations and requirements
of governmental agencies having jurisdiction and with the rules, regulations and
requirements of any board of fire underwriters or similar body.  Notwithstanding
the foregoing, Tenant may make non-structural alterations costing in the
aggregate less than $10,000 in any one year of the term without the prior
written consent of Landlord, provided that Tenant promptly informs Landlord in
writing of the nature of the alterations, the cost thereof and the contractor
engaged or proposed to be engaged to perform such work, and provided further
that all such work complies with clauses (ii) and (iii) above.  Landlord's
consent to any requested alteration shall not create on the part of Landlord or
cause Landlord to incur any responsibility or liability for such alteration's
compliance with all laws, rules and regulations of federal, state, county,
municipal and other governmental authorities.  Any alteration made by Tenant
(excluding moveable furniture and trade fixtures not attached to

                                       5
<PAGE>
 
the Premises) shall at once become a part of the Premises and belong to
Landlord. Without limiting the foregoing, all heating, lighting, electrical
(including all wiring, conduit, outlets, drops, buss ducts, main and subpanels),
air conditioning, partitioning, drapery and carpet installations made by Tenant,
regardless of how attached to the Premises, together with all other alterations
that have become an integral part of the Project in which the Premises are a
part, shall be and become part of the Premises and belong to Landlord upon
installation and shall not be deemed trade fixtures and, subject to Landlord's
right to require removal and restoration as specified herein, shall remain upon
and be surrendered with the Premises at the termination of the lease.

     If Landlord consents to the making of any alteration by Tenant, the same
shall be made by Tenant at its sole risk, cost and expense and only after
Landlord's written approval of any contractor or person selected by Tenant for
that purpose, and the same shall be made at such time and in such manner as
Landlord may from time to time designate.  Tenant shall, if required by
Landlord, secure at Tenant's cost a completion and lien indemnity bond for such
work.  Upon the expiration or sooner termination of the term, Landlord may, at
its sole option, require Tenant, at Tenant's sole cost and expense, to promptly
remove any such alteration made by Tenant and designated by Landlord to be
removed, repair any damage to the Premises caused by such removal and restore
the Premises to their condition prior to Tenant's alteration, normal wear and
tear excepted.  Any moveable furniture and equipment or trade fixtures remaining
on the Premises at the expiration or other termination of the term shall become
the property of the Landlord; provided, however, in addition to all other
remedies available to Landlord at law or in equity, Landlord may (i) require
Tenant to remove same or (ii) remove same at Tenant's cost, and Tenant shall be
liable to Landlord for all damages incurred by Landlord related thereto.

     If during the term any alteration, addition or change of the Premises is
required by law, regulation, ordinance or order of any public authority, due to
Tenant's particular use, occupancy or alteration of the Premises, Tenant, at its
sole cost and expense, shall promptly make the same.  If during the term any
alteration, addition or change to the Premises which is not due to Tenant's
particular use, occupancy or alteration of the Premises, to the Common Area, or
to the Project in which the Premises is located is required by law, regulation,
ordinance or order of any public or quasi-public authority, and it is
impractical in Landlord's judgment for the affected tenants to individually make
such alteration, addition or change, Landlord shall make such alteration,
addition or change and the cost thereof shall be a common area charge and Tenant
shall pay its percentage share of such cost to Landlord as provided in paragraph
16.

     9.  REPAIR AND MAINTENANCE

         By entry hereunder, Tenant accepts the Premises as being in good and
sanitary order, condition and repair.  Except as expressly provided below,
Tenant shall at its sole cost keep and maintain the entire Premises and every
part thereof including, without limitation, the windows, window frames, plate
glass, glazing, elevators within the Premises, truck doors, doors and all door
hardware, the interior walls and partitions, lighting and the electrical,
mechanical, and plumbing systems.  Tenant shall also repair and maintain the
heating and air conditioning systems (unless Landlord has elected to keep and
maintain the heating and air conditioning systems as provided below) which shall
include, without limitation, a periodic maintenance

                                       6
<PAGE>
 
agreement with a reputable and licensed heating and air conditioning service
company.  If Tenant's use of the heating and air conditioning systems is limited
to normal business hours (8:00 a.m. to 6:00 p.m.), such agreement shall provide
for service at least as often as every 60 days; if Tenant's use of the heating
or air conditioning systems extends beyond such normal business hours this
service shall be as often as may be required by Landlord and in any event such
service shall meet all warranty enforcement requirements of such equipment and
comply with all manufacturer recommended maintenance.  Landlord may elect, at
its option, to keep and maintain the heating and air conditioning systems of the
Premises and in such event, Tenant shall pay to Landlord upon demand the full
cost of such maintenance.

     Subject to the provisions of paragraph 17, Landlord shall keep and maintain
the roof, structural elements, foundation and exterior walls of the buildings
constituting the Project and Common Area in good order and repair.  Tenant
waives all rights under and benefits of California Civil Code Sections 1932(1),
1941, and 1942 and under any similar law, statute or ordinance now or hereafter
in effect.  The cost of the repairs and maintenance which are the obligation of
Landlord hereunder, including without limitation, maintenance contracts and
supplies, materials, equipment and tools used in such repairs and maintenance
shall be a common area charge and Tenant shall pay its percentage share of such
costs to Landlord as provided in paragraph 16; provided, however, that if any
repairs or maintenance is required because of an act or omission of Tenant, or
its agents, employees or invitees, Tenant shall pay to Landlord upon demand the
full cost of such repairs or maintenance.

     10.  LIENS

          Tenant shall keep the Premises and the Project free from any liens
arising out of any work performed, materials furnished or obligations incurred
by Tenant, its agents, employees or contractors.  Upon Tenant's receipt of a
preliminary twenty (20) day notice filed by a claimant pursuant to California
Civil Code Section 3097, Tenant shall immediately provide Landlord with a copy
of such notice.  Should any lien be recorded against the Project, Tenant shall
give immediate notice of such lien to Landlord.  In the event that Tenant shall
not, within ten (10) days following the imposition of such lien, cause the same
to be released of record, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but no obligation, to cause the same to
be released by such means as it shall deem proper, including payment of the
claim giving rise to such lien.  All sums paid by Landlord for such purpose, and
all expenses (including attorneys' fees) incurred by it in connection therewith,
shall be payable to Landlord by Tenant on demand with interest at the rate of
twelve percent (12%) per annum or the maximum rate permitted by law, whichever
is less.  Landlord shall have the right at all times to post and keep posted on
the Premises any notices permitted or required by law, or which Landlord shall
deem proper for the protection of Landlord, the Premises and the Project and any
other party having an interest therein, from mechanics' and materialmen's liens
and like liens.  Tenant shall give Landlord at least fifteen (15) days prior
notice of the date of commencement of any construction on the Premises in order
to permit the posting of such notices.  In the event Tenant is required to post
an improvement bond with a public agency in connection with any work performed
by Tenant on or to the Premises, Tenant shall include Landlord as an additional
obligee.

                                       7
<PAGE>
 
     11.  INSURANCE

          Tenant, at its sole cost and expense, shall keep in force during the
term (i) commercial general liability and property damage insurance with a
combined single limit of at least $2,000,000 per occurrence insuring against
personal or bodily injury to or death of persons occurring in, on or about the
Premises or Project and any and all liability of the insureds with respect to
the Premises or arising out of Tenant's maintenance, use or occupancy of the
Premises and all areas appurtenant thereto, (ii) direct physical loss-special
insurance covering the leasehold improvements in the Premises and all of
Tenant's equipment, trade fixtures, appliances, furniture, furnishings, and
personal property from time to time located in, on or about the Premises, with
coverage in the amount of the full replacement cost thereof, and (iii) Worker's
Compensation Insurance as required by law, together with employer's liability
coverage with a limit of not less than $1,000,000 for bodily injury for each
accident and for bodily injury by disease for each employee.  Tenant's
commercial general liability and property damage insurance and Tenant's Workers
Compensation Insurance shall be endorsed to provide that said insurance shall
not be cancelled or reduced except upon at least thirty (30) days prior written
notice to Landlord.  Further, Tenant's commercial general liability and property
damage insurance shall be primary and shall be endorsed to provide that Landlord
and McCandless Management Corporation, and their respective partners, officers,
directors and employees and such other persons or entities as directed from time
to time by Landlord shall be named as additional insureds for all liability
using ISO Bureau Form CG20111185 (or a successor form) or such other endorsement
form reasonably acceptable to Landlord; shall contain a severability of interest
clause and a cross-liability endorsement; shall be endorsed to provide that the
limits and aggregates apply per location using ISO Bureau Form CG25041185 (or a
successor form) or such other endorsement form reasonably acceptable to
Landlord; and shall be issued by an insurance company admitted to transact
business in the State of California and rated A+VIII or better in Best's
Insurance Reports (or successor report).  The deductibles for all insurance
required to be maintained by Tenant hereunder shall be satisfactory to Landlord.
The commercial general liability insurance carried by Tenant shall specifically
insure the performance by Tenant of the indemnification provisions set forth in
paragraph 18 of this lease provided, however, nothing contained in this
paragraph 11 shall be construed to limit the liability of Tenant under the
indemnification provisions set forth in said paragraph 18.  If Landlord or any
of the additional insureds named on any of Tenant's insurance, have other
insurance which is applicable to the covered loss on a contributing, excess or
contingent basis, the amount of the Tenant's insurance company's liability under
the policy of insurance maintained by Tenant shall not be reduced by the
existence of such other insurance.  Any insurance carried by Landlord or any of
the additional insureds named on Tenant's insurance policies shall be excess and
non-contributing with the insurance so provided by Tenant.

     Tenant shall, prior to the commencement of the term and at least thirty
(30) days prior to any renewal date of any insurance policy required to be
maintained by Tenant pursuant to this paragraph, provide Landlord with a
completed Certificate of Insurance, using a form acceptable in Landlord's
reasonable judgement, attaching thereto copies of all endorsements required to
be provided by Tenant under this lease.  Tenant agrees to increase the coverage
or otherwise comply with changes in connection with said commercial general
liability, property damage, direct physical loss and Worker's Compensation
Insurance as Landlord or Landlord's lender

                                       8
<PAGE>
 
may from time to time require.

     Landlord shall obtain and keep in force a policy or policies of insurance
covering loss or damage to the Premises and Project, in the amount of the full
replacement value thereof, providing protection against those perils included
within the classification of "all risk" insurance, with increased cost of
reconstruction and contingent liability (including demolition), plus a policy of
rental income insurance in the amount of one hundred percent (100%) of twelve
(12) months' rent (including sums paid as additional rent) and such other
insurance as Landlord or Landlord's lender may from time to time require.
Landlord may, but shall not be obligated to, obtain flood and/or earthquake
insurance.  Landlord shall have no liability to Tenant if Landlord elects not to
obtain flood and/or earthquake insurance.  The cost of all such insurance
purchased by Landlord, plus any charges for deferred payment of premiums and the
amount of any deductible incurred upon any covered loss within the Project,
shall be common area charges and Tenant shall pay to Landlord its percentage
share of such costs as provided in paragraph 16.  If the cost of insurance is
increased due to Tenant's use of the Premises, then Tenant shall pay to Landlord
upon demand the full cost of such increase.

     Landlord and Tenant hereby mutually waive any and all rights of recovery
against one another for real or personal property loss or damage occurring to
the Premises or the Project, or any part thereof, or to any personal property
therein, from perils insured against under fire and extended insurance and any
other property insurance policies existing for the benefit of the respective
parties so long as such insurance permits waiver of liability and contains a
waiver of subrogation without additional premiums.

     If Tenant does not take out and maintain insurance as required pursuant to
this paragraph 11, Landlord may, but shall not be obligated to, take out the
necessary insurance and pay the premium therefor, and Tenant shall repay to
Landlord promptly on demand, as additional rent, the amount so paid.  In
addition, Landlord may recover from Tenant and Tenant agrees to pay, as
additional rent, any and all reasonable expenses (including attorney fees) and
damages which Landlord may sustain by reason of the failure of Tenant to obtain
and maintain such insurance, it being expressly declared that the expenses and
damages of Landlord shall not be limited to the amount of the premiums thereon.

     12.  UTILITIES AND SERVICE

          Tenant shall pay for all water, gas, light, heat, power, electricity,
telephone, trash pickup, sewer charges and all other services supplied to or
consumed on the Premises.  In the event that any service is not separately
metered or billed to the Premises, the cost of such utility service or other
service shall be a common area charge and Tenant shall pay its percentage share
of such cost to Landlord as provided in paragraph 16.  In addition, the cost of
all utilities and services furnished by Landlord to the Common Area shall be a
common area charge and Tenant shall pay its percentage share of such cost to
Landlord as provided in paragraph 16.

     If Tenant's use of any such utility or service is materially in excess of
the average furnished to the other tenants of the Project, and such utility or
service is not separately metered, then Tenant shall pay to Landlord upon
demand, as additional rent, the full cost of such excess

                                       9
<PAGE>
 
use, or Landlord may cause such utility or service to be separately metered, in
which case Tenant shall pay the full cost of such utility or service and
reimburse Landlord upon demand for the cost of installing the separate meter.

     Except if caused by Landlord's active negligence or willful misconduct,
Landlord shall not be liable for, and Tenant shall not be entitled to any
abatement or reduction of rent by reason of, the failure of any person or entity
to furnish any of the foregoing services when such failure is caused by
accident, breakage, repairs, strikes, lockouts or other labor disturbances or
labor disputes of any character, governmental moratoriums, regulations or other
governmental actions, or by any other cause, similar or dissimilar, beyond the
reasonable control of Landlord.  In addition, Tenant shall not be relieved from
the performance of any covenant or agreement in this lease because of any such
failure, and no eviction of Tenant shall result from such failure.

     13.  TAXES AND OTHER CHARGES

          All real estate taxes and assessments and other taxes, fees and
charges of every kind or nature, foreseen or unforeseen, which are levied,
assessed or imposed upon Landlord and/or against the Premises, building, Common
Area or Project, or any part thereof by any federal, state, county, regional,
municipal or other governmental or quasi-public authority, together with any
increases therein for any reason, shall be a common area charge and Tenant shall
pay its percentage share of such costs to Landlord as provided in paragraph 16.
By way of illustration and not limitation, "other taxes, fees and charges" as
used herein include any and all taxes payable by Landlord (other than state and
federal personal or corporate income taxes measured by the net income of
Landlord from all sources, and premium taxes), whether or not now customary or
within the contemplation of the parties hereto, (i) upon, allocable to, or
measured by the rent payable hereunder, including, without limitation, any gross
income or excise tax levied by the local, state or federal government with
respect to the receipt of such rent, (ii) upon or with respect to the
possession, leasing, operation, management, maintenance, alteration, repair, use
or occupancy by Tenant of the Premises or any part thereof, (iii) upon or
measured by the value of Tenant's personal property or leasehold improvements
located in the Premises, (iv) upon this transaction or any document to which
Tenant is a party creating or transferring an interest or estate in the
Premises, (v) upon or with respect to vehicles, parking or the number of persons
employed in or about the Project, and (vi) any tax, license, franchise fee or
other imposition upon Landlord which is otherwise measured by or based in whole
or in part upon the Project or any portion thereof.  If Landlord contests any
such tax, fee or charge, the cost and expense incurred by Landlord thereby
(including, but not limited to, costs of attorneys and experts) shall also be
common area charges and Tenant shall pay its percentage share of such costs to
Landlord as provided in paragraph 16 and Tenant shall be entitled to its
proportionate share of any resulting rebate.  In the event the Premises and any
improvements installed therein by Tenant or Landlord are valued by the assessor
disproportionately higher than those of other tenants in the building or Project
or in the event alterations or improvements are made to the Premises, Tenant's
percentage share of such taxes, assessments, fees and/or charges shall be
readjusted upward accordingly and Tenant agrees to pay such readjusted share.
Such determination shall be made by Landlord from the respective valuations
assigned in the assessor's work sheet or such other information as may be
reasonably available and Landlord's determination thereof shall be conclusive.

                                       10

     Tenant agrees to pay, before delinquency, any and all taxes levied or
assessed during the term hereof upon Tenant's equipment, furniture, fixtures and
other personal property located in the Premises, including carpeting and other
property installed by Tenant notwithstanding that such carpeting or other
property has become a part of the Premises.  If any of Tenant's personal
property shall be assessed with the Project, Tenant shall pay to Landlord, as
additional rent, the amount attributable to Tenant's personal property within
ten (10) days after receipt of a written statement from Landlord setting forth
the amount of such taxes, assessments and public charges attributable to
Tenant's personal property.

     14.  ENTRY BY LANDLORD

          Landlord reserves, and shall at all reasonable times have, the right
to enter the Premises upon twenty-four (24) hours prior notice (except in case
of emergency) (i) to inspect the Premises, (ii) to supply services to be
provided by Landlord hereunder, (iii) to show the Premises to prospective
purchasers, lenders or tenants and to put `for sale' or `for lease' signs
thereon, (iv) to post notices required or allowed by this lease or by law, (v)
to alter, improve or repair the Premises and any portion of the Project, and
(vi) to erect scaffolding and other necessary structures in or through the
Premises or the Project where reasonably required by the character of the work
to be performed.  Tenant may accompany Landlord during any such entry to the
Premises.  Landlord shall not be liable in any manner for any inconvenience,
disturbance, loss of business, nuisance or other damage arising from Landlord's
entry and acts pursuant to this paragraph and Tenant shall not be entitled to an
abatement or reduction of rent if Landlord exercises any rights reserved in this
paragraph.  For each of the foregoing purposes, Landlord shall at all times have
and retain a key with which to unlock all of the doors in, on and about the
Premises (excluding Tenant's vaults, safes and similar areas designated in
writing by Tenant in advance), and Landlord shall have the right to use any and
all means which Landlord may deem proper to open said doors in an emergency in
order to obtain entry to the Premises.  Any entry by Landlord to the Premises
pursuant to this paragraph shall not under any circumstances be construed or
deemed to be a forcible or unlawful entry into or a detainer of the Premises or
an eviction, actual or constructive, of Tenant from the Premises or any portion
thereof.  Landlord shall use reasonable efforts to minimize disruption of
Tenant's business during any such entry.

     15.  COMMON AREA; PARKING

          Subject to the terms and conditions of this lease and such rules and
regulations as Landlord may from time to time prescribe, Tenant and Tenant's
employees and invitees shall, in common with other occupants of the Project, and
their respective employees and invitees and others entitled to the use thereof,
have the nonexclusive right to use the access roads, parking areas and
facilities within the Project provided and designated by Landlord for the
general use and convenience of the occupants of the Project which areas and
facilities shall include, but not be limited to, sidewalks, parking, refuse,
landscape and plaza areas, roofs and building exteriors, which areas and
facilities are referred to herein as "Common Area".  This right shall terminate
upon the termination of this lease.

     Landlord reserves the right from time to time to make changes in the shape,
size, location, amount and extent of the Common Area.  Landlord shall also have
the right at any

                                       11
<PAGE>
 
time to change the name, number or designation by which the Project is commonly
known.  Landlord further reserves the right to promulgate such rules and
regulations relating to the use of the Common Area, and any part thereof, as
Landlord may deem appropriate for the best interests of the occupants of the
Project.  The rules and regulations shall be binding upon Tenant upon delivery
of a copy of them to Tenant and Tenant shall abide by them and cooperate in
their observance.  Such rules and regulations may be amended by Landlord from
time to time, with or without advance notice, provided Tenant will not be in
default until it has received notice of such amendment or change.

     Tenant shall have the nonexclusive use of one hundred eighty (180) parking
spaces in the Common Area as designated from time to time by Landlord.  Landlord
reserves the right at its sole option to assign and label parking spaces, but it
is specifically agreed that Landlord is not responsible for policing any such
parking spaces.  Tenant shall not at any time park or permit the parking of
Tenant's trucks or other vehicles, or the trucks or other vehicles of others,
adjacent to loading areas so as to interfere in any way with the use of such
areas; nor shall Tenant at any time park or permit the parking of Tenant's
vehicles or trucks, or the vehicles or trucks of Tenant's suppliers or others,
in any portion of the Common Area not designated by Landlord for such use by
Tenant.  Tenant shall not park or permit any inoperative vehicle or equipment to
be parked on any portion of the Common Area.

     Landlord shall operate, manage and maintain the Common Area.  The manner in
which the Common Area shall be operated, managed and maintained and the
expenditures for such operation, management and maintenance shall be at the sole
discretion of Landlord.  The cost of such maintenance, operation and management
of the Common Area, including but not limited to landscaping, repair of paving,
parking lots and sidewalks, security and exterminator services and salaries and
employee benefits (including union benefits) of on-site and accounting personnel
engaged in such maintenance and operations management, shall be a common area
charge and Tenant shall pay to Landlord its percentage share of such costs as
provided in paragraph 16.

     16.  COMMON AREA CHARGES

          Tenant shall pay to Landlord, as additional rent, an amount equal to
(i) twenty percent (20%) of the common area charges of the Project and (ii) 100%
of the common area charges of the building in which the Premises are located.
There shall be no duplication of costs in items (i) and (ii) of the preceding
sentence.  Tenant's percentage share of such common area charges shall be paid
as follows:

     Tenant's estimated monthly payment of common area charges payable by Tenant
during the calendar year in which the term commences is set forth in paragraph
4(b) of this lease.  Prior to the commencement of each succeeding calendar year
of the term (or as soon as practicable thereafter), Landlord shall deliver to
Tenant a written estimate of Tenant's monthly payment of common area charges.
Tenant shall pay, as additional rent, on the first day of each month during the
term in accordance with paragraph 4(b) of the lease, its monthly share of common
area charges as estimated by Landlord.  Within one hundred twenty (120) days of
the end of each calendar year and of the termination of this lease (or as soon
as practicable thereafter), Landlord shall deliver to Tenant a statement of
actual common area charges incurred for the

                                       12
<PAGE>
 
preceding year.  Upon Tenant's written request made within ninety (90) days
after receipt of the statement, Landlord shall provide Tenant with copies of
invoices and other documentation in support thereof.  If such statement shows
that Tenant has paid less than its actual percentage then Tenant shall on demand
pay to Landlord the amount of such deficiency.  If Tenant fails to pay such
deficiency due within ten (10) days after demand, Tenant shall pay an additional
ten percent (10%) of the amount due as a penalty.  If such statement shows that
Tenant has paid more than its actual percentage share then Landlord shall, at
its option, promptly refund such excess to Tenant or credit the amount thereof
to the rent next becoming due from Tenant.  Landlord reserves the right to
revise any estimate of common area charges if actual or projected common area
charges show an increase or decrease in excess of 10% from any earlier estimate
for the same period.  In such event, Landlord shall deliver the revised estimate
to Tenant, together with an explanation of the reasons therefor, and Tenant
shall revise its payments accordingly.  Landlord's and Tenant's obligation with
respect to adjustments at the end of the term or earlier expiration of this
lease shall survive such termination or expiration.

     As used in this lease, "common area charges" shall include, but not be
limited to, (i) all items identified in paragraphs 8, 9, 11, 12, 13 and 15 as
being common area charges; (ii) amortization of such capital improvements having
a useful life greater than one year as Landlord may have installed for the
purpose of reducing operating costs and/or to comply with all laws, rules and
regulations of federal, state, county, municipal and other governmental
authorities now or hereafter in effect (Tenant's share of any such capital
improvement shall equal Tenant's proportionate share of the fraction of the cost
of such capital improvement equal to the remaining term of the lease over the
useful life of such capital improvement); (iii) salaries and employee benefits
(including union benefits) of personnel engaged in the operation and maintenance
of the Project (or the building in which the Premises are located) and payroll
taxes applicable thereto; (iv) supplies, materials, equipment and tools used or
required in connection with the operation and maintenance of the Project; (v)
licenses, permits and inspection fees; (vi) a reasonable reserve for repairs and
replacement of equipment used in the maintenance and operation of the Project;
(vii) all other operating costs incurred by Landlord in maintaining and
operating the Project; and (viii) an amount equal to five percent (5%) of the
actual expenditures for the aggregate of all other common area charges as
compensation for Landlord's accounting and processing services.

     17.  DAMAGE BY FIRE; CASUALTY

          In the event the Premises are damaged by any casualty which is covered
under an insurance policy required to be maintained by Landlord pursuant to
paragraph 11, Landlord shall be entitled to the use of all insurance proceeds
and shall repair such damage as soon as reasonably possible and this lease shall
continue in full force and effect.

     In the event the Premises are damaged by any casualty not covered under an
insurance policy required to be maintained pursuant to paragraph 11, Landlord
may, at Landlord's option, either (i) repair such damage, at Landlord's expense,
as soon as reasonably possible, in which event this lease shall continue in full
force and effect, or (ii) give written notice to Tenant within thirty (30) days
after the date of the occurrence of such damages of Landlord's intention to
cancel and terminate this lease as of the date of the occurrence of the damages;
provided,

                                       13
<PAGE>
 
however, that if such damage is caused by an act or omission of Tenant or its
agent, servants or employees, then Tenant shall repair such damage promptly at
its sole cost and expense.  In the event Landlord elects to terminate this lease
pursuant hereto, Tenant shall have the right within ten (10) days after receipt
of the required notice to notify Landlord in writing of Tenant's intention to
repair such damage at Tenant's expense, without reimbursement from Landlord, in
which event this lease shall continue in full force and effect and Tenant shall
proceed to make such repairs as soon as reasonably possible.  If Tenant does not
give such notice within the ten (10) day period, this lease shall be cancelled
and terminated as of the date of the occurrence of such damage.  Under no
circumstances shall Landlord be required to repair any injury or damage to (by
fire or other cause), or to make any restoration or replacement of, any of
Tenant's personal property, trade fixtures or property leased from third
parties, whether or not the same is attached to the Premises.

     If the Premises are totally destroyed during the term from any cause
(including any destruction required by any authorized public authority), whether
or not covered by the insurance required under paragraph 11, this lease shall
automatically terminate as of the date of such total destruction; provided,
however, that if the Premises can reasonably and lawfully be repaired or
restored within twelve (12) months of the date of destruction to substantially
the condition existing prior to such destruction and if the proceeds of the
insurance payable to the Landlord by reason of such destruction are sufficient
to pay the cost of such repair or restoration, then the insurance proceeds shall
be so applied, Landlord shall promptly repair and restore the Premises and this
lease shall continue, without interruption, in full force and effect.  If the
Premises are totally destroyed during the last twelve (12) months of the term,
either Landlord or Tenant may at its option cancel and terminate this lease as
of the date of occurrence of such damage by giving written notice to the other
of its election to do so within thirty (30) days after the occurrence of such
damage.

     If the Premises are partially or totally destroyed or damaged and Landlord
or Tenant repair them pursuant to this lease, the rent payable hereunder
(including Tenant's proportionate share of common area charges) for the period
during which such damage and repair continues shall be abated only in proportion
to the square footage of the Premises rendered untenantable to Tenant by such
damage or destruction.  Tenant shall have no claim against Landlord for any
damage, loss or expense suffered by reason of any such damage, destruction,
repair or restoration.  The parties waive the provisions of California Civil
Code sections 1932(2) and 1933(4) (which provisions permit the termination of a
lease upon destruction of the leased premises), and hereby agree that the
provisions of this paragraph 17 shall govern in the event of such destruction.

     18.  INDEMNIFICATION

          Landlord shall not be liable to Tenant and Tenant hereby waives all
claims against Landlord for any injury to or death of any person or damage to or
destruction of property in or about the Premises or the Project by or from any
cause whatsoever except the failure of Landlord to perform its obligations under
this lease where such failure has persisted for an unreasonable period of time
after notice of such failure.  Without limiting the foregoing, Landlord shall
not be liable to Tenant for any injury to or death of any person or damages to
or

                                       14
<PAGE>
 
destruction of property by reason of, or arising from, any latent defect in the
Premises or Project or the act or negligence of any other tenant of the Project.
Tenant shall immediately notify Landlord of any defect in the Premises or
Project.

     Except as to injury to persons or damage to property the principal cause of
which is (i) Landlord's active negligence or willful misconduct, or (ii) the
failure by Landlord to observe any of the terms and conditions of this lease,
Tenant shall hold Landlord harmless from and defend Landlord against any claim,
liability, loss, damage or expense (including attorney fees) arising out of any
injury to or death of any person or damage to or destruction of property
occurring in, on or about the Premises from any cause whatsoever or on account
of the use, condition, occupational safety or occupancy of the Premises.  Tenant
shall further hold Landlord harmless from and defend Landlord against any claim,
liability, loss, damage or expense (including attorney fees) arising (i) from
Tenant's use of the Premises or from the conduct of its business or from any
activity or work done, permitted or suffered by Tenant or its agents or
employees in or about the Premises or Project, (ii) out of the failure of Tenant
to observe or comply with Tenant's obligation to observe and comply with laws or
other requirements as set forth in paragraph 7, (iii) by reason of Tenant's use,
handling, storage, or disposal of toxic or hazardous materials or waste, (iv) by
reason of any labor or service performed for, or materials used by or furnished
to, Tenant or any contractor engaged by Tenant with respect to the Premises, or
(v) from any other act, neglect, fault or omission of Tenant or its agents or
employees.

     The provisions of this paragraph 18 shall survive the expiration or earlier
termination of this lease.

     19.  ASSIGNMENT AND SUBLETTING

          Tenant shall not voluntarily assign, encumber or otherwise transfer
its interest in this lease or in the Premises, or sublease all or any part of
the Premises, or allow any other person or entity to occupy or use all or any
part of the Premises, without first obtaining

                                       15
<PAGE>
 
Landlord's written consent, which consent shall not be unreasonably withheld,
and otherwise complying with the requirements of this paragraph 19. Any
assignment, encumbrance or sublease without Landlord's consent, shall constitute
a default.

     If Tenant desires to sublet or assign all or any portion of the Premises,
upon obtaining a written letter of intent from a proposed subtenant or assignee,
Tenant shall give Landlord written notice thereof, specifying the projected
commencement date of the proposed sublet or assignment (which date shall be not
less than thirty (30) days or more than ninety (90) days after the date of
Landlord's receipt of such notice), the portions of the Premises proposed to be
sublet or assigned, the terms and conditions of the proposed assignment or
sublease (including the rent to be paid by the proposed assignee or subtenant)
and the name, address and telephone number of the proposed assignee or
subtenant.  Tenant shall further provide Landlord with such other information
concerning the proposed assignee or subtenant as requested by Landlord.  For a
period of thirty (30) days after Landlord's receipt of Tenant's written notice,
Landlord shall have the option, exercisable by delivering written notice to
Tenant, to terminate this lease as of the date specified in Landlord's written
notice to Tenant, which date shall not be less than thirty (30) days nor more
than ninety (90) days after the date of Landlord's written notice to Tenant.  If
Landlord exercises its option to terminate this lease as provided in the
foregoing sentence, Landlord may, if it so elects, enter into a new lease for
the Premises or any portion thereof with the proposed assignee or subtenant or
any other third party on such terms as Landlord and such proposed assignee or
subtenant or other third party may agree; in such event, Tenant shall not be
entitled to any portion of the profit, if any, which Landlord may realize on
account of such termination and reletting.  Notwithstanding the above,
Landlord's option to terminate this lease as specified above in this
subparagraph shall not apply to (i) subleases by Tenant to not more than two (2)
subtenants for not more than fifty percent (50%) of the Premises in the
aggregate and which expire not later than the last day of the twenty-fourth
(24th) lease month of the initial lease term; or (ii) subleases by Tenant to not
more than two (2) subtenants for not more than twenty-five percent (25%) of the
Premises in the aggregate and which expire not later than the last day of the
forty-eighth (48th) lease month of the initial lease term.

     If Landlord does not elect to terminate this lease as provided hereinabove
in this paragraph 19 and if Landlord consents in writing to the proposed
assignment or sublet, Tenant shall be free to assign or sublet all or a portion
of the Premises subject to the following conditions: (i) any sublease shall be
on the same terms set forth in the notice given to Landlord; (ii) no sublease
shall be valid and no subtenant shall take possession of the sublet premises
until an executed counterpart of such sublease has been delivered to Landlord;
(iii) no subtenant shall have a further right to sublet; (iv) any sums or other
economic consideration received by Tenant as a result of such assignment or
sublet (except rental or other payments received which are attributable to the
amortization over the term of this lease of the cost of (a) leasehold
improvements constructed for such assignees or subtenant and (b) brokerage fees)
whether denominated rentals or otherwise, which exceed, in the aggregate, the
total sums which Tenant is obligated to pay Landlord under this lease (prorated
to reflect obligations allocable to that portion of the Premises subject to such
sublease), shall be payable to Landlord as additional rent under this lease
without affecting or reducing any other obligation of Tenant hereunder; (v) no
sublet or assignment shall release Tenant of Tenant's obligation or alter the
primary liability of Tenant to pay the rent and to perform all other obligations
to be performed by Tenant hereunder;

                                       16
<PAGE>
 
and (vi) any assignee or subtenant must expressly agree to assume and perform
all of the covenants and conditions of Tenant under this lease.  Tenant shall
pay to Landlord promptly upon demand as additional rent, Landlord's reasonable
attorneys' fees and other costs incurred for reviewing, processing or
documenting any requested assignment or sublease, whether or not Landlord's
consent is granted.  Tenant shall not be entitled to assign this lease or
sublease all or any part of the Premises (and any attempt to do so shall be
voidable by Landlord) during any period in which Tenant is in default under this
lease.

     If Tenant is a partnership, a withdrawal or change, voluntary or
involuntary or by operation of law, of any general partner or the dissolution of
the partnership shall be deemed an assignment of this lease subject to all the
conditions of this paragraph 19.  If Tenant is a corporation any dissolution,
merger, consolidation or other reorganization of Tenant or the sale or other
transfer of a controlling percentage of the capital stock of Tenant or the sale
of more than fifty percent (50%) of the value of Tenant's assets shall be an
assignment of this lease subject to all the conditions of this paragraph 19.
The term "controlling percentage" means the ownership of, and the right to vote,
stock possessing more than 50% of the total combined voting power of all classes
of Tenant's capital stock issued, outstanding and entitled to vote.  This
paragraph shall not apply if Tenant is a corporation the stock of which is
traded through an exchange.

     The acceptance of rent by Landlord from any other person shall not be
deemed to be a waiver by Landlord of any provision hereof.  Consent to one
assignment or sublet shall not be deemed consent to any subsequent assignment or
sublet.  In the event of default by any assignee of Tenant or any successor of
Tenant in the performance of any of the terms hereof, Landlord may proceed
directly against Tenant without the necessity of exhausting remedies against
such assignee or successor.  Landlord may consent to subsequent assignments or
sublets of this lease or amendments or modifications to this lease with
assignees of Tenant without notifying Tenant, or any successor of Tenant, and
without obtaining its or their consent thereto and such action shall not relieve
Tenant of liability under this lease; provided, however, Tenant shall not be
liable for any increase in Tenant's obligations under this lease without
Tenant's written consent thereto.

     No interest of Tenant in this lease shall be assignable by operation of law
(including, without limitation, the transfer of this lease by testacy or
intestacy).  Each of the following acts shall be considered an involuntary
assignment: (1) if Tenant is or becomes bankrupt or insolvent, makes an
assignment for the benefit of creditors or institutes a proceeding under the
Bankruptcy Act in which Tenant is the bankrupt; or, if Tenant is a partnership
or consists of more than one person or entity, if any partner of the partnership
or other person or entity is or becomes bankrupt or insolvent, or makes an
assignment for the benefit of creditors; (ii) if a writ of attachment or
execution is levied on this lease; or (iii) if, in any proceeding or action to
which Tenant is a party, a receiver is appointed with authority to take
possession of the Premises.  An involuntary assignment shall constitute a
default by Tenant and Landlord shall have the right to elect to terminate this
lease, in which case this lease shall not be treated as an asset of Tenant.

     Tenant immediately and irrevocably assigns to Landlord, as security for
Tenant's obligations under this lease, all rent from any subletting of all or a
part of the Premises as

                                       17
<PAGE>
 
permitted by this lease, and Landlord, as assignee and as attorney-in-fact for
Tenant, or a receiver of Tenant appointed on Landlord's application, may collect
such rent and apply it toward Tenant's obligations under this lease; except
that, until the occurrence of an act or default by Tenant, Tenant shall have the
right to collect such rent, subject to promptly forwarding to Landlord any
portion thereof to which Landlord is entitled pursuant to this paragraph 19.

     Notwithstanding the above requirement that Tenant obtain the consent of
Landlord prior to any assignment or sublet, Tenant may, without obtaining the
prior consent of Landlord, assign or sublease the whole or any part of the
Premises to any corporation or other entity which controls, is controlled by, or
is under common control with Tenant, provided that (i) Tenant shall give written
notice thereof to Landlord in the manner required for other assignments or
subleases by this paragraph 19; (ii) Tenant shall continue to be fully obligated
under this lease; (iii) any such assignee or sublessee shall expressly assume
and agree to perform all the terms and conditions of this lease to be performed
by Tenant; and (iv) any such assignment or sublet shall be subject to all other
terms and conditions of this paragraph 19 pertaining to assignments and/or
sublets (excepting only the requirement concerning prior written consent of
Landlord).

     20.  DEFAULT

          The occurrence of any of the following shall constitute a default by
Tenant: (i) failure of Tenant to pay any rent or other sum payable hereunder
within five (5) days after the date that such payment becomes due; (ii)
abandonment of the Premises (Tenant's failure to occupy and conduct business in
the Premises for fourteen (14) consecutive days shall be deemed an abandonment);
(iii) failure of Tenant to deliver to Landlord any instrument, assurance,
financial statement, subordination agreement or certificate of estoppel required
under this Lease within the time period specified for such performance if the
failure continues for five (5) days after written notice of the failure from
Landlord to Tenant; or (iv) failure of Tenant to perform any other obligation
under this lease if the failure to perform is not cured within thirty (30) days
after written notice thereof has been given to Tenant (provided that if such
default cannot reasonably be cured within thirty (30) days, Tenant shall not be
in default if Tenant commences to cure such failure to perform within the thirty
(30) day period and diligently and in good faith continues to cure the failure
to perform), except in the case of an emergency or dangerous condition, in which
case Tenant's time to perform shall be that time period which is reasonable
under the circumstances.  The notice referred to in clauses (iii) and (iv) above
shall specify the failure to perform and the applicable lease provision and
shall demand that Tenant perform the provisions of this lease within the
applicable period of time.  No notice shall be deemed a forfeiture or
termination of this lease unless Landlord so elects in the notice.  No notice
shall be required in the event of abandonment or vacation of the Premises.

     In addition to the above, the occurrence of any of the following events
shall also constitute a default by Tenant: (i) Tenant fails to pay its debts as
they become due or admits in writing its inability to pay its debts, or makes a
general assignment for the benefit of creditors (for purposes of determining
whether Tenant is not paying its debts as they become due, a debt shall be
deemed overdue upon the earliest to occur of the following: thirty (30) days
from the date a statement therefor has been rendered; the date on which any
action or proceeding therefor

                                       18
<PAGE>
 
is commenced; or the date on which a formal notice of default or demand has been
sent); (ii) Tenant fails to furnish to Landlord a schedule of Tenant's aged
accounts payable within ten (10) days after Landlord's written request (not to
exceed two (2) requests per calendar year); or (iii) any financial statements
given to Landlord by Tenant, any assignee of Tenant, subtenant of Tenant, any
guarantor of Tenant, or successor in interest of Tenant (including, without
limitation, any schedule of Tenant's aged accounts payable) are materially
false.  At any time during the term of this lease Landlord, at Landlord's
option, shall have the right to receive from Tenant, upon Landlord's request, a
current annual balance sheet for Landlord's review.  If the balance sheet shows
a negative net worth, Landlord may terminate this lease by giving Tenant sixty
(60) days prior written notice.

     In the event of a default by Tenant, then Landlord, in addition to any
other rights and remedies of Landlord at law or in equity, shall have the right
either to terminate Tenant's right to possession of the Premises (and thereby
terminate this lease) or, from time to time and without termination of this
lease, to relet the Premises or any part thereof for the account and in the name
of Tenant for such term and on such terms and conditions as Landlord in its sole
discretion may deem advisable, with the right to make alterations and repairs to
the Premises.

     Should Landlord elect to keep this lease in full force and effect, Landlord
shall have the right to enforce all of Landlord's rights and remedies under this
lease, including but not limited to the right to recover and to relet the
Premises and such other rights and remedies as Landlord may have under
California Civil Code Section 1951.4 (or successor Code section) or any other
California statute.  If Landlord relets the Premises, then Tenant shall pay to
Landlord, as soon as ascertained, the costs and expenses incurred by Landlord in
such reletting and in making alterations and repairs.  Rentals received by
Landlord from such reletting shall be applied (i) to the payment of any
indebtedness due hereunder, other than basic rent and common area charges, from
Tenant to Landlord; (ii) to the payment of the cost of any repairs necessary to
return the Premises to good condition normal wear and tear excepted, including
the cost of alterations and the cost of storing any of Tenant's property left on
the Premises at the time of reletting; and (iii) to the payment of basic rent or
common area charges due and unpaid hereunder.  The residue, if any, shall be
held by Landlord and applied in payment of future rent or damages in the event
of termination as the same may become due and payable hereunder and the balance,
if any at the end of the term of this lease, shall be paid to Tenant.  Should
the basic rent and common area charges received from time to time from such
reletting during any month be less than that agreed to be paid during that month
by Tenant hereunder, Tenant shall pay such deficiency to Landlord.  Such
deficiency shall be calculated and paid monthly.  No such reletting of the
Premises by Landlord shall be construed as an election on its part to terminate
this lease unless a notice of such intention is given to Tenant or unless the
termination hereof is decreed by a court of competent jurisdiction.
Notwithstanding any such reletting without termination, Landlord may at any time
thereafter elect to terminate this lease for such previous breach, provided it
has not been cured.

     Should Landlord at any time terminate this lease for any breach, in
addition to any other remedy it may have, it shall have the immediate right of
entry and may remove all persons and property from the Premises and shall have
all the rights and remedies of a landlord provided by California Civil Code
Section 1951.2 or any successor code section.  Upon such termination, in

                                       19
<PAGE>
 
addition to all its other rights and remedies, Landlord shall be entitled to
recover from Tenant all damages it may incur by reason of such breach, including
the cost of recovering the Premises and including (i) the worth at the time of
award of the unpaid rent which had been earned at the time of termination; (ii)
the worth at the time of award of the amount by which the unpaid rent which
would have been earned after termination until the time of award exceeds the
amount of such rental loss that Tenant proves could have been reasonably
avoided; (iii) the worth at the time of the award of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided; and
(iv) any other amount necessary to compensate Landlord for all the detriment
proximately caused by Tenant's failure to perform its obligations under this
lease or which in the ordinary course of events would be likely to result
therefrom.  The "worth at the time of award" of the amounts referred to in (i)
and (ii) above is computed by allowing interest at the rate of twelve percent
(12%) per annum.  The "worth at the time of award" of the amount referred to in
(iii) above shall be computed by discounting such amount at the discount rate of
the federal reserve bank of San Francisco at the time of award plus one percent
(1%).  Tenant waives the provisions of Section 1179 of the California Code of
Civil Procedure (which Section allows Tenant to petition of court of competent
jurisdiction for relief against forfeiture of this lease).  Property removed
from the Premises may be stored in a public or private warehouse or elsewhere at
the sole cost and expense of Tenant.  In the event that Tenant shall not
immediately pay the cost of storage of such property after the same has been
stored for a period of thirty (30) days or more, Landlord may sell any or all
thereof at a public or private sale in such manner and at such times and places
that Landlord, in its sole discretion, may deem proper, without notice to or
demand upon Tenant.

     21.  LANDLORD`S RIGHT TO CURE TENANT'S DEFAULT

          Landlord, at any time after Tenant commits a default, may, but shall
not be obligated to, cure the default at Tenant's cost.  If Landlord at any
time, by reason of Tenant's default, pays any sum or does any act that requires
the payment of any sum, the sum paid by Landlord shall be due immediately from
Tenant to Landlord and shall bear interest at the rate of twelve percent (12%)
per annum or the maximum rate permitted by law, whichever is less, from the date
the sum is paid by Landlord until Landlord is reimbursed by Tenant.  Amounts due
Landlord hereunder shall be additional rent.

     22.  EMINENT DOMAIN

          If all or any part of the Premises shall be taken by any public or
quasi-public authority under the power of eminent domain or conveyance in lieu
thereof, this lease shall terminate as to any portion of the Premises so taken
or conveyed on the date when title vests in the condemnor, and Landlord shall be
entitled to any and all payments, income, rent, award or any interest therein
whatsoever which may be paid or made in connection with such taking or
conveyance.  Tenant shall have no claim against Landlord or otherwise for the
value of any unexpired term of this lease.  Notwithstanding the foregoing,
Tenant shall be entitled to any compensation for depreciation to and cost of
removal of Tenant's equipment and fixtures and any compensation for its
relocation expenses necessitated by such taking, but in each case only to the
extent the condemning authority makes a separate award therefor or specifically
identifies

                                       20
<PAGE>
 
a portion of the award as being therefor.  Each party waives the provisions of
Section 1265.130 of the California Code of Civil Procedure (which section allows
either party to petition the Superior Court to terminate this lease in the event
of a partial taking of the Premises).

     If any action or proceeding is commenced for such taking of the Premises or
any portion thereof or of any other space in the Project, or if Landlord is
advised in writing by any entity or body having the right or power of
condemnation of its intention to condemn the Premises or any portion thereof or
of any other space in the Project, and Landlord shall decide to discontinue the
use and operation of the Project or decide to demolish, alter or rebuild the
Project, then Landlord shall have the right to terminate this lease by giving
Tenant written notice thereof within sixty (60) days of the earlier of the date
of Landlord's receipt of such notice of intention to condemn or the commencement
of said action or proceeding.  Such termination shall be effective as of the
last day of the calendar month next following the month in which such notice is
given or the date on which title shall vest in the condemnor, whichever occurs
first.

     In the event of a partial taking, or conveyance in lieu thereof, of the
Premises and fifty percent (50%) or more of the number of square feet in the
Premises are taken then Tenant may terminate this lease.  Any election by Tenant
to so terminate shall be by written notice given to Landlord within sixty (60)
days from the date of such taking or conveyance and shall be effective on the
last day of the calendar month next following the month in which such notice is
given or the date on which title shall vest in the condemnor, whichever occurs
first.

     If a portion of the Premises is taken by power of eminent domain or
conveyance in lieu thereof and neither Landlord nor Tenant terminates this lease
as provided above, then this lease shall continue in full force and effect as to
the part of the Premises not so taken or conveyed and all payments of rent shall
be apportioned as of the date of such taking or conveyance so that thereafter
the amounts to be paid by Tenant shall be in the ratio that the area of the
portion of the Premises not so taken bears to the total area of the Premises
prior to such taking.

     23.  NOTICE AND COVENANT TO SURRENDER

          On the last day of the term or on the effective date of any earlier
termination, Tenant shall surrender to Landlord the Premises in its condition
existing as of the commencement of the term and, except as otherwise provided by
Landlord pursuant to the terms of paragraph 8 of this lease, all of the
improvements and alterations made to the Premises in their condition existing as
of the date of completion of construction and/or installation (normal wear and
tear excepted), with all originally painted interior walls washed or repainted
if marked or damaged, interior vinyl covered walls cleaned and repaired or
replaced if marked or damaged, all carpets shampooed and cleaned, the air
conditioning and heating system serviced and repaired by a reputable and
licensed service firm (unless Landlord has elected to maintain such system
pursuant to paragraph 9 of this lease) and all floors cleaned and waxed; all to
the reasonable satisfaction of Landlord.  On or prior to the last day of the
term or the effective date of any earlier termination, Tenant shall remove all
of Tenant's personal property and trade fixtures, together with improvements or
alterations that Tenant is obligated to remove pursuant to the provisions of
paragraph 8 of this lease, from the Premises, and all such property not removed
shall be deemed abandoned.  In addition, on or prior to the expiration or
earlier

                                       21
<PAGE>
 
termination of this lease, Tenant shall remove, at Tenant's sole cost and
expense, all telephone, other communication, computer and any other cabling and
wiring of any sort installed by or for Tenant in the space above the suspended
ceiling of the Premises or anywhere else in the Premises and shall promptly
repair any damage to the suspended ceiling, lights, light fixtures, walls and
any other part of the Premises resulting from such removal.

     If the Premises are not surrendered as required in this paragraph.  Tenant
shall indemnify Landlord against all loss, liability and expense (including but
not limited to, attorney fees) resulting from the failure by Tenant in so
surrendering the Premises, including, without limitation, any claims made by any
succeeding tenants.  It is agreed between Landlord and Tenant that the
provisions of this paragraph shall survive termination of this lease.

     24.  TENANT'S QUITCLAIM

          At the expiration or earlier termination of this lease, Tenant shall
execute, acknowledge and deliver to Landlord, within ten (10) days after written
demand from Landlord to Tenant, any quitclaim deed or other document required to
remove the cloud or encumbrance created by this lease from the real property of
which the Premises are a part.  This obligation shall survive said expiration or
termination.

     25.  HOLDING OVER

          Any holding over after the expiration or termination of this lease
with the written consent of Landlord shall be construed to be a tenancy from
month-to-month at the monthly rent agreed upon by Landlord and Tenant, but in no
event less than the monthly rent payable under this lease for the last lease
month before the date of such expiration or termination.  All provisions of this
lease, except (i) as modified by the preceding sentence and (ii) those
provisions pertaining to the term, expansion rights and any option to extend
shall apply to the month-to-month tenancy.

     If Tenant shall retain possession of the Premises or any part thereof
without Landlord's written consent following the expiration or sooner
termination of this lease for any reason, then Tenant shall pay to Landlord for
each day of such retention one hundred fifty percent (150%) of the amount of the
daily rental in effect during the last lease month prior to the date of such
expiration or termination.  The term "daily rental" as used in the preceding
sentence shall mean the monthly rental divided by thirty.  Tenant shall also
indemnify and hold Landlord harmless from any loss, liability and expense
(including, but not limited to, attorneys fees) resulting from delay by Tenant
in surrendering the Premises, including without limitation any claims made by
any succeeding tenant founded on such delay.  Acceptance of rent by Landlord
following expiration or termination shall not constitute a renewal of this
lease, and nothing contained in this paragraph shall waive Landlord's right of
re-entry or any other right.  Tenant shall be only a Tenant at sufferance,
whether or not Landlord accepts any rent from tenant, while Tenant is holding
over without Landlord's written consent.

     The provisions of this paragraph 25 are in addition to, and do not affect,
Landlord's right of re-entry or other rights hereunder or provided by law.
Nothing in this paragraph 25 shall be

                                       22
<PAGE>
 
construed as implied consent by Landlord to any holding over by Tenant.
Landlord expressly reserves the right to require Tenant to surrender possession
of the Premises to Landlord as provided in this Lease on expiration or other
termination of this Lease.  The provisions of this paragraph 25 shall not be
considered to limit or constitute a waiver of any other rights or remedies of
Landlord provided in this Lease or at law.  The provisions of this paragraph 25
shall survive the expiration or early termination of this lease.

     26.  SUBORDINATION

          In the event Landlord's title or leasehold interest is now or
hereafter encumbered in order to secure a loan to Landlord, Tenant shall, at the
request of Landlord or the lender, execute in writing an agreement subordinating
its rights under this lease to the lien of such encumbrance, or, if so
requested, agreeing that the lien of lender's encumbrance shall be or remain
subject and subordinate to the rights of Tenant under this lease.  Tenant hereby
irrevocably appoints Landlord the attorney-in-fact of Tenant to execute, deliver
and record any such instrument or instruments for and in the name and on behalf
of Tenant.  Notwithstanding any such subordination, Tenant's possession under
this lease shall not be disturbed if Tenant is not in default and so long as
Tenant shall pay all amounts due hereunder and otherwise observe and perform all
provisions of this lease.  In addition, if in connection with any such loan the
lender shall request reasonable modifications of this lease as a condition to
such financing, Tenant will not unreasonably withhold, delay or defer its
consent thereof, provided that such modifications do not increase the
obligations of Tenant hereunder or materially adversely affect the leasehold
interest hereby created or Tenant's rights hereunder.

     27.  CERTIFICATE OF ESTOPPEL

          Each party shall, within five (5) calendar days after request
therefor, execute and deliver to the other party, in recordable form, a
certificate stating that the lease is unmodified and in full force and effect,
or in full force and effect as modified and stating the modifications.  The
certificate shall also state the amount of the monthly rent, the date to which
monthly rent has been paid in advance, the amount of the security deposit and/or
prepaid monthly rent, and, if the request is made by Landlord, shall include
such other items as Landlord or Landlord's lender may reasonably request.
Failure to deliver such certificate within such time shall constitute a
conclusive acknowledgment by the party failing to deliver the certificate that
the lease is in full force and effect and has not been modified except as may be
represented by the party requesting the certificate.  Any such certificate
requested by Landlord may be conclusively relied upon by any prospective
purchaser or encumbrancer of the Premises or Project.  Further, within five (5)
calendar days following written request made from time to time by Landlord,
Tenant shall furnish to Landlord current financial statements of Tenant.

     28.  SALE BY LANDLORD

          In the event the original Landlord hereunder, or any successor owner
of the Project or Premises, shall sell or convey the Project or Premises, all
liabilities and obligations on the part of the original Landlord, or such
successor owner, under this lease accruing thereafter shall terminate, and
thereupon all such liabilities and obligations shall be binding upon the new

                                       23
<PAGE>
 
owner.  Tenant agrees to attorn to such new owner and to look solely to such new
owner for performance of any and all such liabilities and obligations, provided
such new owner agrees to assume and be bound by the terms of this lease.

     29.  ATTORNMENT TO LENDER OR THIRD PARTY

          In the event the interest of Landlord in the land and buildings in
which the Premises are located (whether such interest of Landlord is a fee title
interest or a leasehold interest) is encumbered by deed of trust, and such
interest is acquired by a lender or any other third party through judicial
foreclosure or by exercise of a power of sale at private trustee's foreclosure
sale, Tenant hereby agrees to release Landlord of any obligation arising on or
after any such foreclosure sale and provided such purchaser agrees to assume and
be bound by the terms of this lease, Tenant shall attorn to the purchaser at any
such foreclosure sale and to recognize such purchaser as the Landlord under this
lease.

     30.  DEFAULT BY LANDLORD

          Landlord shall not be in default unless Landlord fails to perform
obligations required of Landlord within a reasonable time, but in no event
earlier than thirty (30) days after written notice by Tenant to Landlord and to
the holder of any first mortgage or deed of trust covering the Premises (whose
name and address shall be provided to Tenant upon written request) specifying
wherein landlord has failed to perform such obligations; provided, however, that
if the nature of Landlord's obligations is such that more than thirty (30) days
are required for performance, then Landlord shall not be in default if Landlord
commences performance within such thirty (30) day period and thereafter
diligently prosecutes the same to completion.

     If Landlord is in default of this lease, Tenant's sole remedy shall be to
institute suit against Landlord in a court of competent jurisdiction, and Tenant
shall have no right to offset any sums expended by Tenant as a result of
Landlord's default against future rent and other sums due and payable pursuant
to this lease.  If Landlord is in default of this lease, and as a consequence
Tenant recovers a money judgment against Landlord, the judgment shall be
satisfied only out of the proceeds of sale received on execution of the judgment
and levy against the right, title and interest of Landlord in the Project of
which the Premises are a part, and out of rent or other income from such real
property receivable by Landlord or out of the consideration received by Landlord
from the sale or other disposition of all or any part of Landlord's right, title
and interest in the Project of which the Premises are a part.  Neither Landlord
nor any of the partners comprising the partnership designated as Landlord shall
be personally liable for any deficiency.

     31.  CONSTRUCTION CHANGES

          It is understood that the description of the Premises and the location
of ductwork, plumbing and other facilities therein are subject to such changes
as Landlord or Landlord's architect determines to be desirable in the course of
construction of the Premises and/or the improvements constructed or being
constructed therein, and no such changes or any changes in plans for any other
portions of the Project, shall affect this lease or entitle Tenant to any

                                       24
<PAGE>
 
reduction of rent hereunder or result in any liability of Landlord to Tenant,
provided such changes do not result in any permanent material detriment to the
operation of Tenant's business.

     32.  MEASUREMENT OF PREMISES

          Tenant understands and agrees that any reference to square footage of
the Premises is approximate only and includes all interior partitions and
columns, one-half of exterior walls, and one-half of the partitions separating
the Premises from the rest of the Project, Tenant's proportionate share of the
Common Area and, if applicable, covered areas immediately outside the entry
doors or loading docks.  Tenant waives any claim against Landlord regarding the
accuracy of any such measurement and agrees that there shall not be any
adjustment in basic rent or common area charges or other amounts payable
hereunder by reason of inaccuracies in such measurement.

     33.  ATTORNEY FEES

          If either party commences an action against the other party arising
out of or in connection with this lease, the prevailing party shall be entitled
to have and recover from the losing party all expenses of litigation, including,
without limitation, travel expenses, reasonable attorney fees, expert witness
fees, trial and appellate court costs, and deposition and transcript expenses.
If either party becomes a party to any litigation concerning this lease, or
concerning the Premises or the Project, by reason of any act or omission of the
other party or its authorized representatives, the party that causes the other
party to become involved in the litigation shall be liable to the other party
for all expenses of litigation, including, without limitation, travel expenses,
attorney fees, expert witness fees, trial and appellate court costs, and
deposition and transcript expenses.

     34.  SURRENDER

          The voluntary or other surrender of this lease or the Premises by
Tenant, or a mutual cancellation of this lease, shall not work a merger, and at
the option of Landlord shall either terminate all or any existing subleases or
subtenancies or operate as an assignment to Landlord of all or any such
subleases or subtenancies.

     35.  WAIVER

          No delay or omission in the exercise of any right or remedy of
Landlord on any default by Tenant shall impair such right or remedy or be
construed as a waiver.  The receipt and acceptance by Landlord of delinquent
rent or other payments shall not constitute a waiver of any other default and
acceptance of partial payments shall not be construed as a waiver of the balance
of such payment due.  No act or conduct of Landlord, including, without
limitation, the acceptance of keys to the Premises, shall constitute an
acceptance of the surrender of the Premises by Tenant before the expiration of
the term.  Only a written notice from Landlord to Tenant shall constitute
acceptance of the surrender of the Premises and accomplish a termination of this
lease.  Landlord's consent to or approval of any act by Tenant requiring
Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's

                                       25
<PAGE>
 
consent to or approval of any subsequent act by Tenant.  Any waiver by Landlord
of any default must be in writing and shall not be a waiver of any other default
concerning the same or any other provision of this lease.

     36.  EASEMENTS; AIRSPACE RIGHTS

          Landlord reserves the right to alter the boundaries of the Project and
grant easements and dedicate for public use portions of the Project without
Tenant's consent, provided that no such grant or dedication shall interfere with
Tenant's use of the Premises or otherwise cause Tenant to incur cost or expense.
From time to time, and upon Landlord's demand, Tenant shall execute, acknowledge
and deliver to Landlord, in accordance with Landlord's instructions, any and all
documents, instruments, maps or plats necessary to effectuate Tenant's covenants
hereunder.

     This lease confers no rights either with regard to the subsurface of or
airspace above the land on which the Project is located or with regard to
airspace above the building of which the Premises are a part.  Tenant agrees
that no diminution or shutting off of light or view by a structure which is or
may be erected (whether or not by Landlord) on property adjacent to the building
of which the Premises are a part or to property adjacent thereto, shall in any
way affect this lease, or entitle Tenant to any reduction of rent, or result in
any liability of Landlord to Tenant.

     37.  RULES AND REGULATIONS

          Landlord shall have the right from time to time to promulgate rules
and regulations for the safety, care and cleanliness of the Premises, the
Project and the Common Area, or for the preservation of good order.  On delivery
of a copy of such rules and regulations to Tenant, Tenant shall comply with the
rules and regulations, and a violation of any of them shall constitute a default
by Tenant under this lease.  If there is a conflict between the rules and
regulations and any of the provisions of this lease, the provisions of this
lease shall prevail.  Such rules and regulations may be amended by Landlord from
time to time with or without advance notice.

     38.  NOTICES

          Except for legal process which may also be served as provided by law
or as provided herein, all notices, demands, requests, consents and other
communications ("Notices") which may be given or are required to be given by
either party to the other shall be in writing and shall be deemed given to and
received by the party intended to receive such Notice (i) when hand delivered,
(ii) three (3) days after such Notice shall have been deposited, postage
prepaid, to the United States Mail, certified return receipt requested, properly
addressed to the address specified herein, or (iii) date of delivery if sent to
the address specified herein by reputable overnight courier (e.g. Federal
Express or other comparable service), as evidenced by such courier's records.

     Prior to the commencement date, all such Notices from Landlord to Tenant
shall be

                                       26

served or addressed to Tenant at 1605 Wyatt Drive, Santa Clara, California
95054.  On or after the commencement date all such Notices from Landlord to
Tenant shall be addressed to Tenant at the Premises.

     All such Notices by Tenant to Landlord shall be sent to Landlord at its
offices at 3945 Freedom Circle, Suite 640, Santa Clara, California 95054.

     Either party may change its address by notifying the other of such change.

     39.  NAME

          Tenant shall not use the name of the Project for any purpose, other
than as the address of the business conducted by Tenant in the Premises, without
the prior written consent of Landlord.

     40.  GOVERNING LAW; SEVERABILITY

          This lease shall in all respects be governed by and construed in
accordance with the laws of the State of California.  If any provision of this
lease shall be held or rendered invalid, unenforceable or ineffective for any
reason whatsoever, all other provisions hereof shall be and remain in full force
and effect.

convenience of reference only and shall have no effect upon the construction or
interpretation of any provision hereof.

     42.  TIME


          Time is of the essence of this lease and of each and all of its
provisions.

     43.  INTEREST ON PAST DUE OBLIGATIONS; LATE CHARGE

          Any amount due from Tenant to Landlord hereunder which is not paid
within five (5) days of when due shall bear interest at the rate of ten percent
(10%) per annum from when due until paid, unless otherwise specifically provided
herein, but the payment of such interest shall not excuse or cure any default by
Tenant under this lease.  In addition, Tenant acknowledges that late payment by
Tenant to Landlord of basic rent or common area charges or of any other amount
due Landlord from Tenant, will cause Landlord to incur costs not contemplated by
this lease, the exact amount of such costs being extremely difficult and
impractical to fix.  Such costs include, without limitation, processing and
accounting charges, and late charges that may be imposed on Landlord, e.g., by
the terms of any encumbrance and note secured by any encumbrance covering the
Premises.  Therefore, if any such payment due from Tenant is not received by
Landlord within five (5) days of when due, Tenant shall pay to Landlord an
additional sum of five percent (5%) of the overdue payment as a late charge.
The parties agree that this late charge represents a fair and reasonable
estimate of the costs that Landlord will incur by reason of late payment by
Tenant.  Acceptance of any late charge shall not constitute a waiver of Tenant's
default with respect to the overdue amount, nor prevent Landlord from exercising
any of the other rights and remedies available to Landlord.  No notice to Tenant
of failure to pay shall be required prior to the imposition of such interest
and/or late charge, and any notice period provided for in paragraph 20 shall not
affect the imposition of

                                       28

Landlord.

     49.  ENVIRONMENTAL MATTERS

          A.   TENANT'S COVENANTS REGARDING HAZARDOUS MATERIALS.
               ------------------------------------------------ 

               (1)  HAZARDOUS MATERIALS HANDLING.  Tenant, its agents, invitees,
employees, contractors, sublessees, assigns and/or successors shall not use,
store, dispose, release or otherwise cause to be present or permit the use,
storage, disposal, release or presence of Hazardous Materials (as defined below)
on or about the Premises or Project.  As used herein "Hazardous Materials" shall
mean any petroleum or petroleum byproducts, flammable explosives, asbestos, urea
formaldehyde, radioactive materials or waste and any "hazardous substance",
"hazardous waste", "hazardous materials", "toxic substance" or "toxic waste" as
those terms are defined under the provisions of the California Health and Safety
Code and/or the provisions of the Comprehensive Environmental Response,
Compensation and Liability Act (42 U.S.C. Section 9601 et seq.), as amended by
the Superfund Amendments and Reauthorization Act of 1986 (42 U.S.C. Section 9601
et seq.), or any other hazardous or toxic substance, material or waste which is
or becomes regulated by any local governmental authority, the State of
California or any agency thereof, or the United States Government or any agency
thereof.  Notwithstanding the above, Tenant shall be permitted to store
reasonable quantities of diesel fuel for use by Tenant with its generator (as
described in paragraph 56 below).  Tenant shall:

                    (a) Use, store, and dispose of all such Hazardous Material
in strict compliance with all applicable statutes, ordinances, and regulations
in effect during the lease term that relate to public health and safety and
protection of the environment including the Hazardous Materials Laws as defined
in section 49.A.(2) below.

                    (b) Comply at all times during the lease term with all
Hazardous Materials Laws.

               (2)  NOTICES. Tenant shall immediately notify Landlord in writing
                    ------- 
of: (i) any enforcement, cleanup, removal or other governmental or regulatory
action instituted, completed or threatened pursuant to any law, regulation or
ordinance relating to the industrial hygiene, environmental protection or the
use, analysis, generation, manufacture, storage, presence, disposal or
transportation of any Hazardous Materials (collectively "Hazardous Materials
Laws"); (ii) any claim made or threatened by any person against Tenant, the
Premises, Project or buildings within the Project relating to damage,
contribution, cost recovery, compensation, loss or injury resulting from or
claimed to result from any Hazardous Materials; and (iii) any reports made to
any environmental agency arising out of or in connection with any Hazardous
Materials in, on or removed from the Premises, Project or buildings within the
Project, including any complaints, notices, warnings, reports or asserted
violations in connection therewith. Tenant shall also supply to Landlord as
promptly as possible, and in any event within

                                       30
<PAGE>
 
five (5) business days after Tenant first receives or sends the same, with
copies of all claims, reports, complaints, notices, warnings or asserted
violations relating in any way to the Premises, Project or buildings within the
Project or Tenant's use thereof.  Tenant shall promptly deliver to Landlord
copies of hazardous waste manifests reflecting the legal and proper disposal of
all Hazardous Materials removed from the Premises.

          B.  INDEMNIFICATION OF LANDLORD.  Tenant shall indemnify, defend (by
              ---------------------------                                     
counsel acceptable to Landlord), protect, and hold Landlord, and each of
Landlord's partners, employees, agents, attorneys, successors and assigns, free
and harmless from and against any and all claims, liabilities, penalties,
forfeitures, losses or expenses (including attorneys' fees) for death of or
injury to any person or damage to any property whatsoever (including water
tables and atmosphere), arising from or caused in whole or in part, directly or
indirectly, by Tenant's use, analysis, storage, transportation, disposal,
release, threatened release, discharge or generation of Hazardous Materials to,
in, on, under, about or from the Premises, Project or buildings within the
Project, or (ii) Tenant's failure to comply with any Hazardous Materials Laws
whether knowingly, unknowingly, intentionally or unintentionally.  Tenant's
obligations hereunder shall include, without limitation, and whether foreseeable
or unforeseeable, all costs of any required or necessary repair, cleanup or
detoxification or decontamination of the Premises, Project or buildings within
the Project, and the preparation and implementation of any closure, remedial
action or other required plans in connection therewith.  In addition, Tenant
shall reimburse Landlord for (i) losses in or reductions to rental income
resulting from Tenant's use, storage or disposal of Hazardous Materials, (ii)
all costs of refitting or other alterations to the Premises, Project or
buildings within the Project required as a result of Tenant's use, storage, or
disposal of Hazardous Materials including, without limitation, alterations
required to accommodate an alternate use of the Premises, Project or buildings
within the Project, and (iii) any diminution in the fair market value of the
Premises, Project or buildings within the Project caused by Tenant's use,
storage, or disposal of Hazardous Materials.  For purposes of this paragraph 49,
any acts or omissions of Tenant, or by employees, agents, assignees, contractors
or subcontractors of Tenant or others acting for or on behalf of Tenant (whether
or not they are negligent, intentional, willful or unlawful) shall be strictly
attributable to Tenant.

          C.  LANDLORD'S REPRESENTATION.  Landlord represents that to the actual
              -------------------------                                         
current knowledge of Ms. Brenda Meckenstock, Landlord's Property Manager,
without duty of inquiry or investigation, there are no Hazardous Materials on
the Premises in violation of any Hazardous Materials Laws as-of the date of
execution of this lease by Landlord.

          D.  SURVIVAL.  The provisions of this paragraph 49 shall survive the
              --------                                                        
expiration or earlier termination of the term of this lease.

     50.  SIGNAGE

          Tenant shall not, without obtaining the prior written consent of
Landlord, install or attach any sign or advertising material on any part of the
outside of the Premises, or on any part of the inside of the Premises which is
visible from the outside of the Premises, or in the halls, lobbies, windows or
elevators of the building in which the Premises are located or on or about any
other portion of the Common Area or Project.  If Landlord consents to the
installation

                                       31
<PAGE>
 
of any sign or other advertising material, the location, size, design, color and
other physical aspects thereof shall be subject to Landlord's prior written
approval and shall be in accordance with any sign program applicable to the
Project.  In addition to any other requirements of this paragraph 50, the
installation of any sign or other advertising material by or for Tenant must
comply with all applicable laws, statutes, requirements, rules, ordinances and
any C.C. & R.'s or other similar requirements.  With respect to any permitted
sign installed by or for Tenant, Tenant shall maintain such sign or other
advertising material in good condition and repair and shall remove such sign or
other advertising material on the expiration or earlier termination of the term
of this lease.  The cost of any permitted sign or advertising material and all
costs associated with the installation, maintenance and removal thereof shall be
paid for solely by Tenant.  If Tenant fails to properly maintain or remove any
permitted sign or other advertising material, Landlord may do so at Tenant's
expense.  Any cost reasonably incurred by Landlord in connection with such
maintenance or removal shall be deemed additional rent and shall be paid by
Tenant to Landlord within ten (10) days following written notice from Landlord.
Landlord may remove any unpermitted sign or advertising material without notice
to Tenant and the cost of such removal shall be additional rent and shall be
paid by Tenant within ten (10) days following notice from Landlord.  Landlord
shall not be liable to Tenant for any damage, loss or expense resulting from
Landlord's removal of any sign or advertising material in accordance with this
paragraph 50.  The provisions of this paragraph 50 shall survive the expiration
or earlier termination of this lease.

     51.  SUBMISSION OF LEASE

          The submission of this lease to Tenant for examination or signature by
Tenant is not an offer to lease the Premises to Tenant, nor an agreement by
Landlord to reserve the Premises for Tenant.  Landlord will not be bound to
Tenant until this lease has been duly executed and delivered by both Landlord
and Tenant.

     52.  PREMISES TAKEN "AS IS"

          Tenant is leasing the Premises from Landlord "as is" in their
condition existing as of the date hereof.  Landlord shall have no obligation to
alter or improve the Premises, except to paint the existing painted walls in the
Premises which Tenant does not plan on removing in its initial remodel.

     53.  ADDITIONAL RENT

          All costs, charges, fees, penalties, interest and any other payments
(including Tenant's reimbursement to Landlord of costs incurred by Landlord)
which Tenant is required to make to Landlord pursuant to the terms and
conditions of this lease and any amendments to this lease shall be and
constitute additional rent payable by Tenant to Landlord when due as specified
in this lease and any amendments to this lease.

     54.  [INTENTIONALLY OMITTED]

     55.  OPTION TO EXTEND TERM

                                       32
<PAGE>
 
          Landlord grants to Tenant the option to extend the term for one period
of two (2) years (the "Extended Term") following the expiration of the initial
term set forth in paragraph 2 ("Initial Term") under all the provisions of this
lease except for the amount of the basic rent.  The basic rent for the Extended
Term shall be adjusted to the market rate (as defined in paragraph (c) below);
provided that in no event shall the basic rent for the Extended Term be less
than the basic rent in effect at the expiration of the Initial Term.  This
option is further subject to the following terms and conditions:

          (a) Tenant must deliver its irrevocable written notice of Tenant's
exercise of this option to Landlord not less than six (6) lease months, nor more
than twelve (12) lease months, prior to the expiration of the Initial Term.
Time is of the essence with respect to the time period during which Tenant must
deliver to Landlord its written notice of exercise and, therefore, if Tenant
fails to give Landlord its irrevocable written notice of its exercise of this
option within the time period provided above then this option shall expire and
be of no further force or effect.

          (b) The parties shall have thirty (30) days from the date Landlord
receives Tenant's notice of exercise in which to agree on the amount
constituting the market rate.  If Landlord and Tenant agree on the amount of the
market rate, they shall immediately execute an amendment to this lease setting
forth the expiration date of the Extended Term and the amount of the basic rent
to be paid by Tenant during the Extended Term.  If Landlord and Tenant are
unable to agree on the amount of the market rate within such time period, then
this option shall be of no further effect and this lease shall expire at the end
of the Initial Term.

          (c) As used herein, the "market rate" shall be the monthly rent then
obtained for two (2) year fixed rate leases of comparable terms for premises in
the Project and in buildings and/or projects within the same geographical area
of similar types and identity, quality and location as the Project.

          (d) Common area charges shall continue to be determined and payable as
provided in paragraphs 4 and 16 of this lease.

          (e) Neither party shall have the right to have any court or other
third party determine the market rate or the basic rent.  Tenant shall not
assign or otherwise transfer this option or any interest therein and any attempt
to do so shall render this option null and void.  Tenant shall have no right to
extend the term beyond the Extended Term.  If Tenant is in default under this
lease at the date of delivery of Tenant's notice of exercise to Landlord, then
such notice shall be of no effect and this lease shall expire at the end of the
Initial Term; if Tenant is in default under this lease on the last day of the
Initial Term, then Landlord may in its sole discretion elect to have Tenant's
exercise of this option be of no effect, in which case this lease shall expire
at the end of the Initial Term.

     56.  ADDITIONAL REQUIREMENTS

          Landlord acknowledges that in the future Tenant may wish (i) to create
a raised-floor computer room (not to exceed five thousand [5,000] square feet)
on the first floor of

                                       33
<PAGE>
 
the Premises, which would require the use of not more than two (2) adjacent
parking spaces for equipment necessary to support such computer room, and (ii)
to locate on the roof of the Premises a microwave dish (not to exceed five [5]
feet in diameter) to be used by Tenant exclusively.  Installation of the
foregoing shall be at Tenant's sole cost and expense and shall be deemed
alterations subject to the provisions of paragraph 8 of this lease, provided
that Landlord's consent shall not be unreasonably withheld.

     57.  CAPITAL EXPENDITURES

          Notwithstanding any provision to the contrary in paragraphs 7 and 8 of
this lease, the cost of any capital improvement to the Premises, the Project or
the Common Area which (i) is required to be made by Landlord under paragraph 7
or 8, (ii) has a useful life of more than one (1) year and (iii) the cost of
which exceeds $50,000, shall be amortized over its useful life (including
interest at a rate of two percent (2%) over the then current Prime Rate as
published by the Wall Street Journal) and the monthly amortized cost thereof so
determined shall be included within common area charges and Tenant shall pay its
percentage share thereof as provided in paragraph 16 of this lease throughout
the remaining term of this lease and any extensions thereof.  Any determination
of what constitutes a capital improvement and the useful life of such capital
improvement, shall be made by Landlord in accordance with generally accepted
accounting principles.

     2.   PREMISES.  Landlord hereby leases to Tenant, and Tenant hereby leases
from Landlord, the Premises described in Section 1.3 together with the tenant
improvements described on Exhibit C ("Tenant Improvements") and together with
rights of ingress and egress over public and common areas in the Building and on
the land legally described on Exhibit A ("Land"). Tenant's lease of the Premises
shall be subject to all of the terms and conditions of this Lease. The Premises,
Building, Land, and the improvements on the Land other than the Building, are
sometimes collectively referred to in this Lease as the "Property".
     Landlord shall complete Landlord's Work in accordance with Exhibit C.
Landlord represents that the Building Improvements, upon substantial completion,
shall materially comply with all applicable codes, regulations, ordinances and
laws including without limitation the American With Disabilities Act.
Notwithstanding anything to the contrary in this Lease, Tenant shall provide
Landlord and Landlord's contractor with such access to the Premises as may be
required by Landlord and Landlord's contractor to efficiently perform Landlord's
Work. Tenant acknowledges and agrees that Landlord shall have no obligation to
improve the Premises except as may be expressly set forth on Exhibit C.

     On or before the Commencement Date, Landlord shall recalculate the "net
rentable square feet" of the Premises. The recalculated net rentable square feet
shall be certified by Tenant's architect prior to the Commencement Date. Net
rentable square feet shall be calculated in accordance with BOMA standards,

areas before the confirmation date letter to be sent according to section 3.5.

          2.1  ACCEPTANCE OF PREMISES.  Landlord and Tenant hereby agree that
Landlord's Work as set forth in Exhibit C shall be constructed by Landlord's
contractor, Sabey Construction Inc. Tenant's acceptance of the Premises shall be
"as-is" as of the date the Tenant commences construction on the Premises.

     Within five (5) days ("Inspection Period") after the date Landlord informs
Tenant of such substantial completion of Landlord's Work, Tenant shall make such
inspection of the Premises as Tenant deems appropriate. Except as otherwise
specified by Tenant in writing to Landlord within the Inspection Period, Tenant
shall be deemed to have accepted the Landlord's Work in its condition and except
for latent defects, as of such date of substantial completion. If, as a result
of such inspection, Tenant discovers items of Landlord's Work of a nature
commonly found on a "punch list" (as such term is commonly used in the
construction industry), which it reasonably believes are not completed in
accordance with Exhibit C, Tenant shall notify Landlord of such items prior to
the expiration of the Inspection Period. Landlord shall promptly complete repair
of all punch list items identified in Tenant's notice which it reasonably
believes require repair. The existence of such punch list items shall not
postpone the Commencement Date or the obligation of Tenant to pay Base Rent or
Additional Rent.

          2.2  TENANT ALLOWANCE.   Intentionally Deleted.
 
          2.3  TENANT'S RIGHT OF FIRST REFUSAL.  Landlord grants Tenant the
right of first 

                                       3
<PAGE>
 
refusal during the Term of this Lease to lease the space consisting of
approximately 15,006 net rentable square feet and depicted on Exhibit B as the
First Refusal Space ("First Refusal Space") that Landlord proposes to lease,
subject to the terms and conditions of this Section 2.3. If Tenant is not then
in default under this Lease beyond applicable notice and cure periods and if
Landlord receives a bona fide offer to lease all or part of the First Refusal
Space (the "Offer"), then Landlord shall notify Tenant in writing ("Landlord's
Offer Notice") of the lease term, base rent and additional rent and all other
provisions of the Offer. Within ten (10) days of Tenant's receipt of Landlord's
Offer Notice, Tenant shall notify Landlord in writing ("Tenant's Offer Notice")
of Tenant's election to lease that portion of the First Refusal Space from
Landlord on the lease term, base rent and additional rent provisions of the
Offer. All of the other terms and provisions of such lease shall be the same as
those contained in this Lease (but not including the Tenant Improvement
Allowance described in Section 2.2), to the extent applicable. If Tenant fails
to give Tenant's Offer Notice as provided in this Section 2.3, then Tenant shall
be deemed to have waived its right of first refusal with respect to the First
Refusal Space offered. Time is of the essence with respect to this paragraph. If
Tenant elects not to lease the First Refusal Space, then Landlord shall have the
right to lease the First Refusal Space described in the Offer on any combination
of base rent and additional rent that in the aggregate is equal to or greater
than the base rent and additional rent contemplated by the Offer. In the event
Tenant assigns or subleases all or more than one-half (1/2) of the Premises,
Tenant's right of first refusal under this Section shall automatically terminate
as to such assignee or subtenant.

          2.4  RELOCATION OR TERMINATION.  Intentionally Deleted.

3.   LEASE TERM.

          3.1  DURATION OF LEASE TERM.  Tenant's lease of the Premises shall
commence on the Commencement Date and terminate on the Expiration Date or such
earlier or later date as may be provided for under this Lease. Notwithstanding
anything to the contrary in Section 1.6, if Landlord is unable to deliver
possession of the Premises to Tenant with Landlord's Work constructed by
Landlord's contractor substantially completed in accordance with Exhibit C on
the date specified in Section 1.6 and such delay (to the extent of such delay)
is due to no fault on the part of Tenant, then the Commencement Date shall be
the earlier of the date on which Tenant first occupies the Premises or the date
that is Fifteen (15) days from the date of Landlord's written notice to Tenant
of substantial completion of Landlord's Work and Tenant Improvements constructed
by Landlord's contractor provided for in Section 2, above.

          3.2  EXTENSION OPTION. Provided that Tenant is in compliance with all
the terms and conditions of this Lease or not in default beyond any applicable
cure period both at the time of Tenant's exercise of this option and at the time
the Option Term is scheduled to commence, Tenant shall have the option("Option")
to extend the term of this Lease for two (2) additional periods of five (5)
years (the "Option Term") on the same terms and conditions of this Lease as are
provided for in the initial Term, except as provided below in this Section 3.2
or in Section 3.3 and without any free rent periods or Tenant Improvement
allowances. The Option Term shall commence upon the date of expiration of the
initial Term, or first option term, of this Lease. To exercise its Option,
Tenant must give written notice to Landlord that Tenant is exercising its Option
at least six (6) months before the date of expiration of the initial Term, or
first option term. If, in Landlord's reasonable discretion, Landlord determines
that the creditworthiness of Tenant is materially less than the creditworthiness
of Tenant as of the Lease's execution date, Landlord may nullify Tenant's
exercise of its Option by written notice to Tenant. Tenant acknowledges and
agrees that notwithstanding anything to the contrary in this Lease, the right to
exercise the Option shall not extend to any assignee or subtenant of Tenant, or
to any space assigned or subleased by Tenant, and any attempt to exercise the
Option by any such assignee or subtenant, or by Tenant in connection with such
assigned or subleased space, shall be deemed null and void. Tenant further
acknowledges and agrees that the amount of the Security Deposit payable by
Tenant for the Option Term shall be increased to an amount equal to the first
monthly installment of Fixed Rent payable by Tenant during the Option Term.

          3.3  BASE RENT DURING OPTION TERM.  In the event that Tenant elects
to exercise its Option to extend the Term of this Lease in accordance with the
terms of Section 3.2, the Base Rent for the Option Term shall be equal to the
then-market rate for similarly improved 

                                       4
<PAGE>
 
space in comparable buildings for comparable use in the South Seattle/Tukwila
region; provided,however, that in no event shall the Base Rent during the Option
Term be less than the Base Rent for the last year of the initial Lease Term. The
adjusted Base Rent shall commence on and be payable on the first day of the
Option Term and shall continue thereafter throughout the Option Term.

          3.4  TENANT TERMINATION RIGHT.  Subject to the terms and conditions
of this Section 3.4, Tenant shall have a right to terminate this Lease at the
end of the 60th month of this Lease. Tenant's termination right under this
Section 3.4 may be exercised only by Tenant providing Landlord with written
notice, one hundred eighty (180) days prior to the end of the 60th month, of
this lease, of its intent to exercise its termination right and payment to
Landlord of a termination fee in the amount equal to the unamortized (at 10%)
costs of the Commission and Landlord's costs to provide the demising walls and
to replace or bring in the 1,200 amps of power to be provided in accordance with
Exhibit C, plus 5 months base rent. Landlord will provide Tenant such costs upon
completion of Landlord's Work in accordance with Exhibit C. Tenant's right to
terminate the Lease under this Section 3.4 shall be wholly conditioned upon
Tenant not being in default, after expiration of any applicable notice or cure
periods, under this Lease either at the time of Tenant's exercise of its
termination right or on the date of Tenant's termination of the Lease under this
Section 3.4. In the event Tenant does not exercise its termination right as set
forth in this Section 3.4, then Tenant's termination right shall expire
automatically and have no further force or effect without necessity of notice or
other action by Landlord. Any purported exercise by Tenant of its termination
right other than strictly in accordance with this Section 3.4 shall be void and
have no force or effect.

          3.5  CONFIRMATION OF COMMENCEMENT DATE.  Landlord shall confirm the
Commencement Date to Tenant in writing within a reasonable time after delivery
of the Premises in accordance with this Lease.

          3.6  SURRENDER OF PREMISES.  Subject to Section 12, Tenant shall
promptly and peacefully surrender the Premises to Landlord upon the termination
of the Lease Term in as good a condition as when received by Tenant from
Landlord and/or as thereafter improved, if applicable, normal wear and tear
excepted. Unless Landlord expressly provides otherwise in writing to Tenant,
upon the expiration or termination of this Lease, all improvements and additions
to the Premises except those items set forth on Exhibit C-1 shall be deemed
property of Landlord and shall not be removed by Tenant from the Premises.
Tenant shall be solely responsible for, and shall repair, all damage to the
Property arising out of its surrender of the Premises. In addition to all other
requirements under this Lease, Tenant shall remove any Hazardous Substances, as
such term is defined in Section 6.3, on the Premises which were placed on the
Premises by Tenant, its employees, agents, contractors and/or invitees, prior to
its surrender and vacation of the Premises.

          3.7  HOLDING OVER WITH CONSENT.  If Tenant remains in possession of
the Premises after termination or expiration of the Lease Term with Landlord's
written permission, such tenancy shall be deemed a month-to-month tenancy which
may be terminated by either party upon thirty (30) days notice. During such
tenancy, Tenant shall be bound by all of the terms, covenants and conditions in
this Lease so far as applicable, except that the Base Rent shall be increased to
the greater of (i) the then-quoted rates for similar space in the Building or
(ii) one hundred fifty percent (150%) multiplied by the sum of the monthly
installment of Base Rent and Additional Rent payable for the last month of the
Lease Term.

          3.8  HOLDING OVER WITHOUT CONSENT. If Tenant remains in possession of
the Premises after the termination or expiration of the Lease Term without
Landlord's prior written consent, Tenant shall become a tenant at sufferance
only, subject to all the provisions of this Lease so far as applicable, except
that Base Rent shall be increased to an amount equal to two hundred percent
(200%) multiplied by the sum of the monthly installments of Base Rent and
Additional Rent payable by Tenant during the last month of the Lease Term,
prorated on a daily basis. Acceptance by Landlord of Rent after the termination
of the Lease Term shall not result in a renewal or extension of this Lease. The
provisions of Section 3.7 and this Section 3.8 are in addition to, and shall not
act as a waiver of or otherwise affect, Landlord's right of re-entry or any
other rights of Landlord under this Lease or as provided by law or in equity. If
Tenant fails to

                                       5
<PAGE>
 
surrender the Premises upon the termination of the Lease Term, despite
Landlord's demand to do so, Tenant shall indemnify, defend and hold Landlord
harmless from and against all loss and liability, including, without limitation,
any claim made by any succeeding tenant founded on, or resulting from, such
failure to surrender, including without limitation, any attorneys' fees or costs
associated therewith.

     4.   RENT.

          4.1  PAYMENT. Tenant shall pay Landlord the monthly installments of
Base Rent provided in Section 1.9 and Additional Rent provided in Section 1.11
in lawful money of the United States, in advance, on the Commencement Date and
thereafter on or before the first day of each month throughout the Lease Term.
Base Rent and Additional Rent shall be paid by Tenant without notice or demand,
deduction, abatement, or offset, except as expressly provided herein. Base Rent
and Additional Rent for any partial month at the beginning or end of the Lease
Term shall be prorated in proportion to the number of days in such month. Base
Rent and Additional Rent are collectively referred to in this Lease as "Rent."

          4.2  INTEREST ON LATE PAYMENTS; LATE CHARGE. If any Base Rent or
Additional Rent is not paid on the due date thereof: (i) such overdue amounts
shall bear interest at a rate equal to three (3) percentage points above the
prime rate of interest stated from time to time by Seattle-First National Bank
or its successor, or, in the absence of an established prime rate, five (5)
percentage points over that bank's rate for one year certificates of deposit,
but not in excess of the highest lawful rate permitted under applicable laws,
calculated from the original due date thereof to the date of payment; and (ii)
Tenant shall pay Landlord a late charge equal to five percent (5%) of such
overdue amount. The parties hereby agree that such late charge represents a fair
and reasonable estimate of the costs Landlord will incur by reason of late
payment by Tenant, the exact amount of which would be difficult to ascertain.
Acceptance by Landlord of any partial amounts due under this Section 4 shall in
no event constitute a waiver of Tenant's default with respect to any overdue
amount, nor prevent Landlord from exercising any of its other rights and
remedies granted under this Lease or by law or in equity.

          4.3  ADDRESS FOR PAYMENTS.  Tenant shall pay all Rent to Landlord at
Landlord's Payment Address, or at such other place as may be designated by
Landlord from time to time by written notice to Tenant at least thirty (30) days
prior to the next ensuing payment date.

     5.   SECURITY DEPOSIT.  As security for the full and faithful performance
of every covenant and condition of this Lease to be performed by Tenant, Tenant
shall pay to Landlord the Security Deposit specified in Section 1.13. If Tenant
defaults with respect to any covenant or condition of this Lease, including but
not limited to, the payment of Base Rent or Additional Rent, Landlord may apply
all or any part of the Security Deposit to the payment of any sum in default or
payment of any other sum which Landlord may be required or may in its reasonable
discretion deem necessary to spend or incur by reason of Tenant's default. In
such event, Tenant shall deposit with Landlord the amount so applied within five
(5) days of written demand from Landlord. If Tenant shall have fully complied
with all of the covenants and conditions of this Lease the amount of the
Security Deposit then held by Landlord shall be repaid to Tenant (or, at
Landlord's option, to the last assignee of Tenant's interest under this Lease)
within thirty (30) days after the expiration or sooner termination of this
Lease. In the event of Tenant's default under this Lease, Landlord's right to
retain the Security Deposit shall be deemed to be in addition to any and all
other rights and remedies available to Landlord under this Lease, at law or in
equity. Landlord shall not be required to keep any Security Deposit separate
from its general funds and Tenant shall not be entitled to any interest on the
Security Deposit.
 
     6.   USES; COMPLIANCE WITH LAWS.

          6.1  PERMITTED USES. The Premises are to be used only for the
Permitted Uses, and for no other business or purpose without the prior written
consent of Landlord, which consent may be withheld if Landlord, in its
reasonable discretion, determines that any proposed use is inconsistent with or
detrimental to the maintenance and operation of the Building as a similar office
building or is inconsistent with any restriction on use of the Property
contained in

                                       6
<PAGE>
 
any lease, mortgage or other agreement or instrument by which the Landlord may
be bound or to which any of the Property may be subject.

          6.2  DUTIES AND PROHIBITED CONDUCT.  Notwithstanding anything to the
contrary in this Lease, Tenant shall not commit any act that will increase the
then-existing rate of insurance on the Building without Landlord's prior written
consent. Tenant shall promptly pay upon demand the amount of any increase in
insurance rates caused by the Permitted Uses or by any act or acts of Tenant or
its employees, agents or representatives. Tenant shall not commit or allow to be
committed any waste upon the Premises, or any public or private nuisance or
other act which disturbs the quiet enjoyment of any other tenant of the Property
or which is unlawful. Tenant shall not, without the written consent of Landlord,
use any apparatus, machinery or device in or about the Premises, or act in any
way, which will cause any substantial noise, or any vibration, fumes, or
releases of Hazardous Substances into the surrounding environment. If any of
Tenant's office machines, equipment or activities should disturb the quiet
enjoyment of any other tenant in the Building, cause any substantial noise, or
cause any vibration, fumes or releases of Hazardous Substances, then Tenant, at
Tenant's sole expense, shall provide adequate insulation or take such other
action as may be necessary to eliminate such disturbance, noise, vibration,
fumes or releases. Tenant, at Tenant's expense, shall comply with all laws,
rules, regulations, orders, ordinances and permits relating to the Premises, or
its use or occupancy of the Premises, and shall observe such rules and
regulations as may be adopted by Landlord and made available to Tenant from time
to time. This Lease shall be subject to all applicable zoning ordinances and to
all municipal, county, state and federal laws and regulations governing or
regulating the use of the Premises.

          6.3  ENVIRONMENTAL, HEALTH AND SAFETY LAWS. Without limiting Tenant's
obligations under this Section 6, Tenant in the exercise of its rights and the
performance of its obligations under this Lease shall comply, at Tenant's
expense, with all local, state, or federal laws, rules, regulations, ordinances,
orders and permits now existing, or as hereafter enacted, amended, or issued
concerning environmental, health, or safety matters (collectively, the
"Environmental Laws"). Tenant shall not use the Premises for, or permit anything
to be done in or about the Property which may subject Landlord, any guarantor,
or any mortgagee under any mortgage covering the Property, to liability for
remediation costs or other damages or penalties under any Environmental Laws
resulting from Tenant's use of, or conduct on, the Property, including without
limitation, the use, generation, transportation, management, handling,
treatment, storage, manufacture, emission, release, disposal or deposit of any
radioactive material, hazardous or toxic wastes, hazardous or toxic substances,
any material containing hazardous wastes or hazardous substances (except as they
occur in normal office products or household cleaning products), or any other
pollutant, contaminant, human pathogen or infectious agent as such terms may now
or in the future be defined in any Environmental Laws (collectively, "Hazardous
Substances"), on the Property, adjacent surface waters, soils, underground
waters, or air.

     Landlord shall have the right at all reasonable times upon notice to Tenant
to conduct environmental investigations, including the taking of samples, for
the purpose of detecting or measuring the presence of Hazardous Substances on
the Property. Tenant shall keep Landlord continuously informed by written notice
of all Hazardous Substances which Tenant, or Tenant's employees, agents,
representatives, or contractors, generates, stores or otherwise allows on the
Property. Tenant shall provide Landlord with copies of all documents received or
prepared by Tenant concerning any release of a Hazardous Substance at the
Property, all documents Tenant receives or prepares in connection with any
violation, or alleged violation, of an Environmental Law by Tenant, and all
reports or other documents Tenant is required to provide any governmental
authority under any Environmental Law concerning any Hazardous Substance. Upon
request by Landlord, Tenant shall provide Landlord with all other information
which Landlord reasonably deems necessary or useful for the purpose of
determining whether Tenant is in compliance with all Environmental Laws and
whether the Property, or any part of the Property, is contaminated by any
Hazardous Substances. If Tenant or the Premises is in violation of any
Environmental Law, or in the event of a release of Hazardous Substances into or
on the Property or adjacent surface waters, soils, underground waters, or air,
Tenant shall (i) immediately notify Landlord in writing of such occurrence and
the action necessary to correct or mitigate such occurrence, and (ii) take such
action as is necessary to mitigate and correct such

                                       7
<PAGE>
 
violation or release. Provided, however, Landlord reserves the right, but not
the obligation, to enter the Premises, to act in place of the Tenant (and Tenant
hereby appoints Landlord as its agent for such purposes) and to take such action
as Landlord deems necessary to ensure compliance or to mitigate the violation,
at Tenant's expense. If Landlord has a reasonable belief that Tenant is in
violation of any Environmental Law, or that Tenant's actions or inaction
presents a threat of violation or a threat of damage to the Property, Landlord
reserves the right to enter the Premises and take such corrective or mitigating
action as Landlord reasonably deems necessary. All costs and expenses incurred
by Landlord in connection with any such actions shall become immediately due and
payable by Tenant upon presentation of an invoice therefor.

     Tenant shall not conduct or permit others to conduct environmental testing
on the Premises without first obtaining Landlord's written consent. Tenant shall
promptly inform Landlord of the existence of any environmental study,
evaluation, investigation or results of any environmental testing conducted on
the Premises whenever the same becomes known to Tenant and Tenant shall provide
copies to Landlord, upon request by Landlord and at no cost to Landlord.
Notwithstanding the foregoing, in no event shall Tenant be responsible for or
liable to Landlord for any Hazardous Substances located in the Premises that
existed or were released upon the Premises prior to the Commencement Date of
this Lease. In addition, Landlord hereby agrees to indemnify Tenant for all
remediation costs and other damages resulting form any spill or discharge of
hazardous substances caused by the gross negligence of Landlord to the full
extent of Landlord's negligence. Landlord represents and warrants that to the
best of its knowledge, the Premises are free of any Hazardous Substances.

     7.   SERVICES AND UTILITIES; REPAIRS AND MAINTENANCE.

          7.1  SERVICES AND UTILITIES; LANDLORD'S OBLIGATIONS.

Landlord warrants that the Building's mechanical, electrical and plumbing
systems are designed and suitable for the delivery of heating, ventilation, air-
conditioning ("HVAC"), electrical and water (including sewer) services
sufficient for standard office use. Landlord shall supply the Premises with HVAC
(at 5 watts per square foot), electricity (at 8 watts per square foot connected
load) and, if applicable, water sufficient for standard office use, the cost of
which shall be paid by the Tenant in accordance with Section 8.6. HVAC service
will be limited to 7:00 a.m to 6:00 p.m on weekdays (excluding holidays
recognized by Landlord) ("Normal Business Hours"), except for additional service
as provided for in this Lease. Landlord shall supply Landlord's standard
Building and Property security and fire monitoring services and elevator
service, Landlord's standard trash removal services (excluding disposal of
Hazardous Substances or medical or biological waste) from the Building
compactor, bulb replacement services for Building standard light fixtures, and
Landlord's standard exterior window washing services for Premises' windows.
Landlord shall also provide any janitorial services to the Premises if so
requested by tenant.

     Any service or utility which is separately metered to the Premises by the
utility provider shall be billed directly to Tenant and paid directly by Tenant
to the utility provider. The Base rental rate excludes the cost of janitorial
services to the Premises, and utilities to the Premises, including the estimated
utilities to supply the Premises with building standard HVAC. All other services
or utilities which are required to be provided by Landlord under Section 7.1
which are not separately metered by the service or utility provider shall be
included within "Operating Costs" and shall be paid by Tenant each month as
provided in Section 8. The cost for any services or utilities which are not
separately metered or sub-metered shall be based on Landlord's reasonable
estimate of Tenant's consumption of such utilities. If in the Landlord's
reasonable opinion the Tenant's consumption of any utility is extraordinary,
Landlord shall be entitled to install, maintain and operate, at Tenant's cost, a
monitoring/ metering system(s) in the Premises to measure Tenant's consumption
of water, electricity (including electricity to Tenant's signage, if any) HVAC
or other utilities or services, or to measure the added demands on the Premises
electrical or HVAC systems resulting from Tenant's equipment or lights,
including without limitation, Tenant's improvements pursuant to Exhibit C.

     Landlord's obligation to provide the services and utilities described in
this Section 7.1 is subject to Section 11 (Damage And Destruction) and Section
22 (Condemnation).

                                       8
<PAGE>
 
               7.1.1 ADDITIONAL SERVICES OR UTILITIES. The Building standard
mechanical system is designed to accommodate standard office use heating loads
generated by lights or equipment using up to Five (5) watts per square foot.
Before installing fixtures, lights or equipment in the Premises which in the
aggregate exceed such amount, or which otherwise consume or require services or
utilities exceeding standard office-type levels, Tenant shall obtain the written
permission of Landlord. Landlord may refuse to grant such permission unless
Tenant agrees to pay Landlord's costs, including Landlord's administrative fee,
for installation of supplementary air conditioning capacity or electrical
systems as necessitated by such equipment or lights. In addition, Tenant shall
pay Landlord as Additional Rent the amount estimated by Landlord (including
Landlord's administrative fee) as the cost of furnishing services or utilities
for the operation of such equipment or lights and the cost of operation and
maintenance of any supplementary air conditioning units necessitated by Tenant's
use of such equipment or lights.

     Landlord may restrict access to the Building in accordance with the
Building's security system, provided that Tenant shall have at all times during
the term of this Lease (24 hours of all days) reasonable access to the Premises.

     If after request by Tenant, Landlord furnishes HVAC or other services or
utilities in addition to the utilities or services required to be provided by
Landlord under this Lease, including without limitation, furnishing utilities or
services at times other than Normal Business Hours or in amounts exceeding
standard office use, then the cost of such non-standard or additional services
or utilities, as reasonably established by Landlord, shall be paid by Tenant as
Additional Rent.

          7.2  SERVICES AND UTILITIES; TENANT'S OBLIGATIONS.   Tenant shall be
solely responsible for providing, and shall pay directly, all charges for
janitorial services to the Premises and for any security services desired by
Tenant in addition to Landlord's standard Building and site security services.
Tenant shall be solely responsible for providing, at Tenant's cost, any backup
electricity generator desired by Tenant. It is understood that except as
provided in Sections 7.1 or 7.4, Landlord shall not be required to provide any
services or utilities to Tenant, and Tenant shall make all necessary
arrangements to have such services and utilities billed directly to Tenant and
paid directly by Tenant. Tenant shall pay its share, as reasonably determined by
Landlord, of any unique services or equipment used by Tenant which are shared by
other tenants of the Building, such as generators, dilution tanks and air
compressors.

          7.3  INTERRUPTION.  Landlord shall not be liable for any loss, injury
or damage to persons or property caused by or resulting from any variation,
interruption, or failure of services or utilities to be provided by Landlord
under this Lease due to any cause whatsoever, including without limitation,
Landlord's failure to make any repairs or perform any maintenance required to be
performed by Landlord under this Lease. However, if Landlord fails to make
repairs within a reasonable time after receiving written notice of the need for
repairs, Tenant shall be allowed to an abatement for rent to the extent said
failure to make said repairs interferes with Tenant's reasonable occupancy of
the Premises. No temporary variation, interruption or failure of services or
utilities to be provided by Landlord under this Lease incident to the making of
repairs, alterations or improvements, or due to accident, strike or conditions
or events beyond Landlord's reasonable control, shall be deemed an eviction of
Tenant or relieve Tenant from any of Tenant's obligations under this Lease.

          7.4  LANDLORD'S REPAIR AND MAINTENANCE OBLIGATIONS. Except as provided
in Sections 9 (Improvements and Alterations by Tenant), 11 (Damage or
Destruction) or 22 (Condemnation), Landlord shall cause to be maintained in
reasonably good order and condition the Premises and the public and common areas
of the Property, such as lobbies, elevators, stairs, corridors, restrooms,
foundation, exterior walls and all aspects of the roof, except with respect to
Tenant's modification of any or all of these areas; provided, however, Tenant
shall be responsible for the cost of repair of damage occasioned by any act or
omission of Tenant or Tenant's officers, contractors, agents, invitees,
licensees or employees, subject to Section 12, Waiver of Subrogation. Landlord
shall maintain and repair the Premises, water, if applicable, and elevator
service at all times during the term of the Lease.

          7.5  TENANT'S REPAIR AND MAINTENANCE OBLIGATIONS.   Except for

                                       9
<PAGE>
 
maintenance, replacements and repairs required to be made or provided by
Landlord under Sections 7.1 or 7.4, Tenant, at its sole cost and expense, shall
provide for the maintenance, repair and replacement within the Premises and all
built-in appliances and equipment which are in the Premises for Tenant's
exclusive use and any security systems or services desired by Tenant in addition
to any such systems or services as may be provided by Landlord under this Lease.

     In performing its obligations under this Section 7, Tenant, at Tenant's
expense, shall comply with all Environmental Laws and all other applicable laws,
ordinances, codes, orders, rules or regulations of any governmental authority.
Tenant shall retain, and shall provide Landlord upon request, copies of Tenant's
maintenance and service contract(s). Except as provided in Section 9 in
connection with Alterations, before making or performing any work, repairs, or
replacement of any kind in the Premises, if such work shall affect the building
systems or costs of operation to Landlord then Tenant shall obtain Landlord's
prior written approval, which approval may be conditioned, on Tenant providing
Landlord with plans and specifications therefor, if applicable, which are
reasonably acceptable to Landlord. All work, maintenance, repairs and
replacements by Tenant under this Lease shall be performed by licensed
contractors acceptable to Landlord. Tenant shall provide Landlord with copies of
all contracts or purchase orders, for such work, maintenance, repairs and
replacements prior to having such work, maintenance, repairs or replacements
performed. Before installing any heavy equipment or fixtures in the Premises,
Tenant shall submit the plans and specifications therefor to Landlord for
Landlord's written approval.

     8.   ADDITIONAL RENT: OPERATING COSTS AND REAL ESTATE TAXES

          8.1  DEFINITIONS.  In addition to the Base Rent, Tenant shall pay to
Landlord each month as Additional Rent Tenant's Share of Taxes and of Operating
Costs as provided in this Section 8, using the following definitions:

               8.1.1 TAXES. "Taxes" shall mean taxes on real property and
personal property, charges and assessments (or any installments thereof due
during the Lease Year) levied with respect to the Property, any improvements,
fixtures and equipment on the Property, and all other property of Landlord, real
or personal, used directly in the operation of the Property, and any taxes
levied or assessed (or any installment thereof due during the Lease Year) in
addition to or lieu of, in whole or in part, such real property or personal
property taxes, or any other tax upon leasing of the Property and/or Building or
rents collected, but not including any federal or state income, estate, business
and occupation, inheritance or franchise tax.

               8.1.2 OPERATING COSTS. "Operating Costs" shall mean all expenses
other than Taxes paid or incurred by Landlord for obtaining services and
products for maintaining, operating, equipment replacement, and repairing the
Property, including without limitation, the Property public and common areas,
and the personal property used in conjunction therewith, and which shall
include, without limitation, the costs of Landlord performing its maintenance
and repair obligations under this Lease, depreciation and amortization of
capital improvements made subsequent to the initial development of the Property
or Building which are designed with a reasonable probability of enhancing the
health and/or safety of the Property or improving the operating efficiency of
the Property or Building, security services for the Property, fire alarm system
monitoring and testing, refuse collection, maintaining water, sewer, storm
drainage and other utility systems and services, common area electricity, gas
and other similar energy sources (excluding electricity for the Premises which
will be charged to the Tenant subject to paragraph 8.6 below), supplies, common
area janitorial and cleaning services, exterior window washing, landscape
planting, maintenance and irrigation, services of independent contractors
(including any market-rate management fees which may be or become payable to
third parties), compensation (including employment taxes and fringe benefits) of
all persons who perform duties in connection with the operation, maintenance and
repair of the Property and its equipment, the maintenance, resurfacing, repair
and striping of parking areas and curbs, downspouts and gutters, lighting and

inspection fees, a management fee, reasonable legal, administrative and

management practices would be considered an expense of maintaining, operating,
or repairing the Property, excluding

                                      10
<PAGE>
 
or deducting, as appropriate costs of any special services rendered to
individual tenants (including Tenant) for which a special charge is collected
including, without limitation, any specially metered charges. Notwithstanding
the foregoing, Operating Costs shall not include the following:

     (1)  attorney's fees, accounting fees and other expenditures incurred in
connection with negotiations, disputes and claims of other tenants or occupants
of the Building, except as specifically otherwise provided in the Lease;

     (2)  costs directly attributable to or for the sole benefit of a tenant,
including Tenant;

     (3)  rental on ground leases or other underlying leases;

     (4)  cost of any work or services to the extent performed for any facility
other than the Building (provided Landlord shall have the right to reasonably
allocate the cost of services provided to more than one facility);

     (5)  costs due to Landlord's willful violation of any governmental rule or
authority;
 
     (6)  charitable or political contributions;
 
     (7)  any fees paid to related parties of Landlord which exceed the market

     (8)  costs of refinancing or selling the property.

               8.1.3 TENANT'S SHARE.  "Tenant's Share" in connection with
Operating Costs and Taxes shall mean Tenant's Share of the Property multiplied
by actual or estimated, as the case may be, Operating Costs or Taxes allocated
to the Property, respectively. Notwithstanding anything to the contrary in this
Section 8.1.3, for purposes of the determination of Operating Costs, to the
extent Operating Costs vary depending upon occupancy type or level of the areas
served, such varying Operating Costs shall be adjusted so that such Operating
Costs shall not reflect material changes to the extent attributable to changes
in occupancy type and/or levels.

          8.2  PAYMENT OF ADDITIONAL RENT FOR ESTIMATED INCREASES IN OPERATING
COSTS AND TAXES.  Within ninety (90) days of the Commencement Date or the close
of each Lease Year, as applicable, or as soon thereafter as is practicable,
Landlord shall provide Tenant with a written statement of Tenant's Share of
estimated Operating Costs and increases in Operating Costs and Taxes for such
Lease Year over actual Operating Costs and Taxes for the Base Year. Tenant shall
pay 1/12 of the amount of such estimated Operating Costs, and increases in
Operating Costs and Taxes as Additional Rent as provided in Section 4 each month
during such Lease Year and until such time as Landlord provides Tenant with a
statement of estimated increases for the subsequent Lease Year. If at any time
or times during such Lease Year, it appears to Landlord that Tenant's Share of
actual Operating Costs and/or actual Taxes will vary from the estimated
Operating Costs and/or Taxes by more than five percent (5%) on an annual basis,
Landlord may, by written notice to Tenant, revise its estimate for such Lease
Year and Additional Rent payable by Tenant under this Section 8.2 for such Lease
Year shall be increased based on Landlord's revised estimate.

          8.3  ACTUAL OPERATING COSTS AND TAXES.  Landlord will make reasonable
efforts within ninety (90) days after the close of each Lease Year during the
Term hereof for which an estimated statement was delivered to Tenant pursuant to
Section 8.2, to deliver to Tenant a written statement ("Reconciliation
Statement") setting forth Tenant's Share of the actual Operating Costs and Taxes
paid or incurred by Landlord during the preceding Lease Year (or such prorated
portion of such Lease Year if this Lease commences or terminates on a day other
than the first or last day of a Lease Year, based on a 365-day Lease Year). If
the actual Operating Costs and/or Taxes shown on the Reconciliation Statement
for any Lease Year exceed estimated Operating Costs and/or Taxes paid by Tenant
to Landlord pursuant to Section 8.2, Tenant shall pay the excess to Landlord as
Additional Rent within thirty (30) days after the date

                                      11
<PAGE>
 
of the Reconciliation Statement. If the Reconciliation Statement shows that
actual Operating Costs and/or Taxes are less than the estimated Operating Costs
and/or Taxes paid by Tenant to Landlord pursuant to Section 8.2, then the amount
of such overpayment shall be credited by Landlord to the next Additional Rent
payable by Tenant (or refunded to Tenant in the event of the termination or
expiration of this Lease within thirty (30) business days of the date of said
termination or expiration ). Notwithstanding anything to the contrary in this
Section 8.3, Tenant's Share of Operating Costs and Taxes for any partial Lease
Year at the end of the Term shall be as shown on Landlord's statement of
estimated Operating Costs and Taxes furnished to Tenant pursuant to Section 8.2.

          8.4  DETERMINATIONS.  The determination of actual and estimated
Operating Costs and Taxes shall be made by Landlord. Landlord or its agent shall
keep records in reasonable detail showing all expenditures made for the items
enumerated in this Section 8.

     Tenant shall have the right at its own cost and expense to review and/or
inspect Landlord's records once in any calendar year with respect to any
Operating Costs shown on Landlord's annual reconciliation statement provided to
Tenant. Tenant shall give Landlord written notice of its intention to conduct
any such audit within ninety (90) days of the date of Landlord's annual
reconciliation statement or Tenant shall be deemed to have waived its audit and
inspection right with respect to the period of time covered in such statement.
Tenant's audit shall be conducted at Landlord's main business office, or at such
other location as Landlord may keep its relevant business records, and on a date
mutually agreed upon by Landlord and Tenant, but in no event earlier than sixty
(60) days from the date of Tenant's notice. Tenant, and its employees, agents,
attorneys and representatives agree that any and all information concerning
Operating Costs or any other information disclosed by Landlord pursuant to any
such audit shall not be disclosed to any other person or entity without the
prior written consent of Landlord, which consent shall be at Landlord's sole
discretion. Prior to providing such confidential information to any of Tenant's
employees, agents, attorneys or representatives, Tenant shall deliver to
Landlord a written acknowledgement of such parties' agreement to be bound by the
terms of this paragraph, in a form satisfactory to Landlord. Nothing in this
paragraph shall relieve Tenant of its obligation under Section 8 to pay
Additional Rent without notice, demand, offset or deduction.

          8.5  TENANT'S PERSONAL PROPERTY TAXES.  Tenant shall pay prior to
delinquency all Personal Property Taxes payable with respect to all Property of
Tenant located on the Premises or the Property and, upon Landlord's request,
shall promptly provide Landlord with written proof of such payment. Solely for
purposes of this Section 8.5, "Property of Tenant" shall include Landlord's
Work, Tenant's Work and all other improvements which are paid for by Tenant, and
"Personal Property Taxes" shall include all property taxes assessed against the
Property of Tenant, whether assessed as real or personal property.

          8.6  TENANT'S UTILITY AND JANITORIAL CHARGES.  Landlord and Tenant
agree that utilities to the Premises including the cost of utilities to provide
Building standard HVAC are not included in the Base Rent. Landlord will
estimate, by meter if possible, the cost of the Tenant's usage of electricity
and natural gas for its Premises, including the cost of utilities to heat and
cool the Premises. Tenant shall pay to the Landlord as Additional Rent each
month the Landlord's estimate of such charges. At the end of each calendar year
the Landlord shall compare the previous 12 months actual charges to its
estimates. Any amounts owing shall be paid by Tenant, and credit amounts shall
be refunded to Tenant in accordance with Section 8.3. Landlord shall adjust its
estimates as provided for in Section 8.2.

     Tenant will also be responsible for any Janitorial services to be provided
to the Premises, but at all times must maintain or have a Janitorial plan in
place to keep the Premises in a clean and orderly condition. Landlord may
request in writing to see such plan or contract of third party service provider.

     9.   IMPROVEMENTS AND ALTERATIONS BY TENANT.  Except for the Tenant
Improvements, Tenant shall not make any changes, alterations, additions or
improvements in or to the Premises ("Alterations"), including, without
limitation, changes to locks on doors or to plumbing or wiring, without first
obtaining the written consent of Landlord,

                                      12
<PAGE>
 
which shall not unreasonably be withheld, and, where required by Landlord, such
Alterations shall be made under the supervision of a competent architect and/or
a licensed structural engineer, and in accordance with plans and specifications,
approved by Landlord, which approval shall not be unreasonably withheld. Prior
to commencing any Alterations, Tenant shall notify Landlord of such work and
Landlord shall perform a good faith asbestos inspection in accordance with
applicable laws and regulations. All work with respect to any Alterations shall
be done in a good and workmanlike manner and shall be diligently prosecuted to
completion. In no event shall Tenant's Alterations change or affect the
strength, exterior appearance, or the mechanical, electrical, or plumbing
services or systems, of the Building without Landlord's consent. Tenant shall
reimburse Landlord upon demand for any sums expended by Landlord for examination
and approval of plans and specifications for any and all Alterations. Tenant
shall also pay Landlord a sum equal to the costs incurred by Landlord during any
inspection or supervision of any and all Alterations. All damages or injury to
the Property caused by any act or omission of Tenant, or Tenant's officers,
contractors, agents, invitees, licensees or employees, or by any persons who may
be in or upon the Property with the express or implied consent of Tenant,
including but not limited to, damage from cracked or broken glass in windows or
doors, shall be paid by Tenant upon demand by Landlord.

     10.  ACCESS. During other than Normal Business Hours, Landlord may restrict
access to the Building in accordance with the Building's security system,
provided that Tenant shall have at all times during the Lease Term (24 hours of
all days) reasonable access to the Premises. Landlord, at Tenant's cost, shall
provide Tenant with security access cards to the Premises if such cards are a
part of the Building's security system at Landlord's cost. Tenant shall permit
Landlord and its agents to enter the Premises at all reasonable times (except in
cases of emergency) for the purpose of inspecting or improving the Premises or
the Building or for performing any of its obligations under this Lease, upon
advance notice to Tenant. Nothing contained in this Section 10 shall be deemed
to impose any obligation upon Landlord not expressly stated elsewhere in this
Lease. When reasonably necessary Landlord may temporarily close entrances,
doors, corridors, elevators or other facilities without liability to Tenant by
reason of such closure and without such action by Landlord being construed as an
eviction of Tenant or release of Tenant from the duty of observing and
performing any of the provisions of this Lease, so long as such action does not
materially and unreasonably interfere with Tenant's access to the leased
Premises. Landlord shall have the right to enter the Premises for the purpose of
showing the Premises to prospective tenants within the period of one hundred
eighty (180) days prior to the expiration or sooner termination of the Lease
Term, provided, Landlord gives at least twenty-four (24) hour notice and abides
by Tenant's reasonable security measures to protect Tenant's trade secrets.

     11.  DAMAGE OR DESTRUCTION.

          11.1 DAMAGE AND REPAIR.  If the Building is damaged by fire or any
other cause to such extent that the cost of restoration, as estimated by
Landlord, will equal or exceed thirty percent (30%) of the replacement value of
the Building (exclusive of foundations) just prior to the occurrence of the
damage, or if insurance proceeds sufficient for restoration are for any reason
unavailable, then Landlord may no later than the one hundred twentieth (120th)
day following the damage, give Tenant a notice of its election to terminate this
Lease.  In the event of such election; (a) this Lease shall be deemed to
terminate on the date that is thirty (30) days from the date of Tenant's receipt
of such notice ("Termination Date"); (b) Tenant shall surrender possession of
the Premises on the Termination Date; and (c) Rent and Additional Rent shall be
apportioned as of the date of Tenant's surrender and any Rent paid for any
period beyond such date shall be repaid to Tenant.  If the cost of restoration
as estimated by Landlord shall amount to less than thirty percent (30%) of said
replacement value of the Building or Property and insurance proceeds sufficient
for restoration are available, or if Landlord does not elect to terminate this
Lease, Landlord shall restore the Building and the Premises (to the extent of
the improvements to the Premises originally provided by Landlord hereunder but
excluding any improvements paid for by Landlord with any tenant allowance or
credits) with reasonable promptness, subject to delays beyond Landlord's control
and delays in the making of insurance adjustments by Landlord, and Tenant shall
have no right to terminate this Lease except as provided in this Section 11. To
the extent that the Premises are rendered untenantable by such damage or by
Landlord's restoration work under this Section, the Base Rent (but not
Additional 

                                      13
<PAGE>
 
Rent) shall proportionately abate, provided, however, in the event such damage
resulted from or was contributed to, directly or indirectly, by the act, fault
or neglect of Tenant, Tenant's officers, contractors, agents, employees,
invitees or licensees, Base Rent shall abate only to the extent Landlord
receives proceeds from any rental income insurance policy received by Landlord
for loss of Rent under this Lease.

          11.2 DESTRUCTION DURING LAST YEAR OF TERM.  Notwithstanding anything
to the contrary in this Lease, in case the Building shall be substantially
destroyed by fire or other cause at any time during the last Lease Year of this
Lease, either Landlord or Tenant may terminate this Lease upon written notice to
the other given within thirty (30) days of the date of such destruction.

          11.3 BUSINESS INTERRUPTION.  No damages, compensation or claim shall
be payable by Landlord for inconvenience, loss of business or annoyance arising
from any damage or destruction, repair or restoration of any portion of the
Premises or the Building. Landlord shall use reasonable efforts to effect such
repairs promptly.

          11.4 TENANT IMPROVEMENTS.  Landlord will not carry insurance of any
kind on any improvements or alterations paid for by Tenant under this Lease or
paid for pursuant to any tenant allowance or credits from Landlord,  or on
Tenant's furniture, furnishings, fixtures, equipment or appurtenances of Tenant
under this Lease and Landlord shall not be obligated to repair any damage
thereto or replace the same.  Tenant shall insure its improvements in accordance
with Section 14.2 and proceeds of such insurance shall be used in any repair or
restoration of the Premises.

          11.5 EXPRESS AGREEMENT.  The provisions of this Section 11 shall be
considered an express agreement governing any case of damage or destruction of
the Building or Premises by fire or other casualty.

     12.  WAIVER OF SUBROGATION. Whether loss or damage is due to the negligence
of either Landlord or Tenant, their agents or employees, or any other cause,
Landlord and Tenant do each hereby release and relieve the other, their agents
or employees, from responsibility for, and waive their entire claim of recovery
for, (i) any loss or damage to the real or personal property of either party
located anywhere on the Property, including the Building itself, arising out of
or incident to the occurrence of any of the perils which are covered, or are
required to be covered under this Lease, by their respective property and
related insurance policies, and (ii) any loss resulting from business
interruption at the Premises or loss of rental income from the Building, arising
out of or incident to the occurrence of any of the perils covered by any
business interruption insurance policy, or by any loss of rental income
insurance policy, which may be held by Landlord or Tenant. Each party shall use
best efforts to cause its insurance carriers to consent to the foregoing waiver
of rights of subrogation against the other party. Notwithstanding the foregoing,
no such release shall be effective unless and to the extent the aforesaid
insurance policy or policies shall expressly permit such a release or contain a
waiver of the carrier's right to be subrogated.

     13.  INDEMNIFICATION.  Landlord shall not be liable for, and Tenant shall
defend (unless Landlord waives its right to such defense, and in any event with
counsel reasonably satisfactory to Landlord), indemnify, hold harmless and
protect Landlord and its employees and agents from any claim, demand, liability,
judgment, award, fine, mechanics' lien or other lien, loss, damage, expense,
penalty, charge or cost of any kind or character (including actual attorney fees
and court costs) which may be made, incurred or asserted by Tenant, Tenant's
agents or employees, contractors, or any third parties (including but not
limited to Landlord's agents, servants or employees), arising directly or
indirectly from: (a) any labor dispute involving Tenant or its agents or
contractors (but excluding labor disputes involving Landlord or its contractors,
subcontractors, or agents); (b) the construction, repair, alteration,
improvement, use, occupancy or enjoyment of the Premises by Tenant its
contractors, agents, employees and/or customers or invitees, (c) injury to, or
death of, any person or persons or damage to, or destruction of, any property
(including without limitation the costs of investigation, removal or remedial
action and disposal of any hazardous or toxic substances, as such terms may be
defined under any applicable federal, state, or municipal law, statute, rule or
regulation) occurring in, on or about 

                                      14
<PAGE>
 
the Premises, unless it is the result of Landlord's negligence or (d) Tenant's
breach of this Lease or the acts or omissions of Tenant or its officers,
directors, shareholders, employees, contractors, subcontractors, or agents (the
"Claims"). Notwithstanding anything to the contrary in this Section 13, nothing
in this Section 13 shall relieve Landlord from responsibility for its
proportionate share of its fault attributable to its negligence or wilful
misconduct in causing any such Claims. TENANT HEREBY WAIVES ITS IMMUNITY WITH
RESPECT TO LANDLORD UNDER THE INDUSTRIAL INSURANCE ACT (RCW TITLE 51) AND/OR THE
LONGSHOREMEN'S AND HARBOR WORKER ACT, AND/OR ANY EQUIVALENT ACTS AND TENANT
EXPRESSLY AGREES TO ASSUME POTENTIAL LIABILITY FOR ACTIONS BROUGHT AGAINST
LANDLORD BY TENANT'S EMPLOYEES. THIS WAIVER HAS BEEN SPECIFICALLY NEGOTIATED BY
THE PARTIES TO THIS LEASE AND TENANT HAS HAD THE OPPORTUNITY TO, AND HAS BEEN
ENCOURAGED TO, CONSULT WITH INDEPENDENT COUNSEL REGARDING THIS WAIVER.

     Without limiting Tenant's obligations under this Section 13, Tenant agrees
to defend, indemnify and hold Landlord harmless from and against any and all
claims, causes of action, regulatory demands, liabilities, fines, penalties,
losses, and expenses, including without limitation, clean-up or other remedial
costs (including attorneys' fees, costs and all other reasonable litigation
expenses when incurred and whether incurred in defense of actual litigation or
in reasonable anticipation of litigation), arising from the existence or
discovery of any Hazardous Substance on the Premises, or the migration of any
Hazardous Substance from the Premises to other properties or into the
surrounding environment, whether (i) made, commenced or incurred during the term
of this Lease, or (ii) made, commenced or incurred after the expiration or
termination of this Lease if arising out of events occurring during the term of
this Lease.

     Tenant shall not be liable for, and Landlord shall defend (unless Tenant
waives its rights to defense, and in any event with counsel reasonably
satisfactory to Tenant), indemnify, hold harmless and protect Tenant and its
employees and agents from any claim, demand, liability, judgment, award, fine,
mechanics lien or other lien, loss, damage, expense, penalty, change or cost of
any kind of character (including reasonable attorneys' fees and court costs)
which may be made, incurred or asserted against Tenant by third parties arising
or resulting from damage to property or injury to person to the extent caused by
the negligence or willful misconduct of Landlord, its employees, agents,
servants or representatives.

     14.  INSURANCE.

          14.1 LIABILITY INSURANCE. Commencing on the earlier of the
Commencement Date or the date Tenant first enters onto the Premises and
continuing throughout the term of this Lease and any renewal hereof, Tenant
shall, at its own expense, keep and maintain in full force and effect, a policy
of commercial general liability insurance including a contractual liability
endorsement covering Tenant's obligations under Section 13, insuring Tenant's
activities upon, in or about the Premises or the Building against claims of
bodily injury or death or property damage or loss with a limit of not less than
$2,000,000 combined single limit per occurrence and annual aggregate.

          14.2 PROPERTY INSURANCE.  Commencing on the earlier of the
Commencement Date or the date Tenant first enters onto the Premises and
continuing throughout the Term of this Lease and any renewal hereof, Tenant
shall, at its own expense, keep and maintain in full force and effect, what is
commonly referred to as "all risk" coverage insurance (but excluding earthquake
and flood) on Tenant's leasehold improvements, including without limitation, any
improvements made by Landlord on behalf of Tenant or pursuant to a tenant
allowance or credit, in an amount not less than the current 100% replacement
value thereof.  Landlord shall not carry insurance on Tenant's leasehold
improvements.

          14.3 INSURANCE POLICY REQUIREMENTS. All policies of insurance required
under this Section 14 shall be issued by companies qualified to do business in
the State of Washington and holding a general policy holder's rating of not less
than "A" and a financial rating of not less than "Class XI" as rated in the most
current available edition of "Best's 

                                      15
<PAGE>
 
Insurance Reports." All such policies shall contain cross-liability endorsements
and shall name Sabey Corporation, David A. Sabey and Sandra L. Sabey ,
Landlord's mortgagees or beneficiaries and such additional individuals or
entities as Landlord may from time to time designate as primary additional
insureds. No insurance policy required under this Section 14 shall be cancelled
or reduced in coverage and each insurance policy shall provide that it is not
subject to cancellation or a reduction in coverage except after thirty (30) days
prior written notice to Landlord. Tenant shall deliver to Landlord upon
Commencement Date or the date Tenant first enters onto the Premises and from
time to time thereafter, a cop of the certificate of insurance evidencing the
existence, endorsements, and amounts of same as required by Landlord. In no
event shall the limits of any insurance policy required under Section 14 be
considered as limiting the liability of Tenant under this Lease. All public
liability, property damage and other policies shall be written as primary
policies, not contributing with or secondary to coverage which Landlord may
carry.

     15.  ASSIGNMENT AND SUBLETTING.

          15.1 ASSIGNMENT OR SUBLEASE. Tenant shall not assign, mortgage,
encumber or otherwise transfer this Lease or sublet the whole or any part of the
Premises without in each case first obtaining Landlord's prior written consent,
which consent may not be unreasonably conditioned, delayed or withheld.

     In no event shall an assignment, subletting or other transfer of the Lease
relieve Tenant of any of its obligations under this Lease.  Consent to any such
assignment, subletting or transfer shall not operate as a waiver of the
necessity for consent to any subsequent assignment, subletting or transfer.

     If such consent is requested and Tenant has subleased at least fifty
percent (50%) of the net rentable square footage of the Premises at any given
time during the term of this Lease, Landlord reserves the right to terminate
this Lease, or, if consent is requested for subletting less than the entire
Premises, to terminate this Lease with respect to the portion for which such
consent is requested, at the proposed effective date of such subletting, in
which event Landlord shall enter into the relationship of Landlord and Tenant
with any such subtenant or assignee, based on the rent (and/or other
compensation) and the term agreed to by such subtenant or assignee and otherwise
upon the terms and conditions of this Lease.

     If Tenant is a corporation, any transfer of this Lease by merger,
consolidation or liquidation, or any change in the ownership of a majority of
its outstanding voting stock, or power to vote a majority of its outstanding
voting stock, shall constitute an assignment for the purpose of this Section 15;
provided, however, for the purposes of this Section 15, a public offering of
stock registered with the SEC, shall not constitute a transfer.  Notwithstanding
any of the foregoing in this Section 15.1, Tenant may merge with or be acquired
by another corporation, Landlord's consent will not be unreasonably withheld
provided that the successor entity (upon consummation of such transaction) has a
net worth at least equal to the net worth of Tenant as of the date of the
execution of this Lease.   If Tenant is a partnership, any transfer of this
Lease by merger, consolidation, liquidation, dissolution, or any change in the
ownership of a majority of the partnership interests shall constitute an
assignment for the purpose of this Section 15.

          15.2 DOCUMENTATION AND EXPENSES.  In connection with each request for
an assignment or subletting Tenant shall:  (i) submit in writing to Landlord the
name and legal composition of the proposed subtenant or assignee, the nature of
the proposed subtenant's or assignee's business to be carried on in the
Premises, the terms and provisions of the proposed sublease or assignment and
such reasonable financial information as Landlord may request concerning the
proposed subtenant or assignee; and (ii) pay Landlord's reasonable costs of
processing such assignment or subletting, including attorneys' fees, upon demand
of Landlord.  Tenant shall provide Landlord with copies of all assignments,
subleases and assumption instruments.

          15.3 TRANSFEREE OBLIGATIONS. As a condition to Landlord's approval of
an assignment, any potential assignee otherwise acceptable to Landlord shall
assume, in writing, all of Tenant's obligations under this Lease and Tenant and
such assignee shall agree, in writing, to 

                                      16
<PAGE>
 
be jointly and severally liable for the performance of all of Tenant's
obligations under this Lease. As a condition to Landlord's approval of any
sublessee otherwise acceptable to Landlord such sublessee shall assume, in
writing, all of Tenant's obligations under this Lease as to the subleased
portion of the Premises and Tenant and such sublessee shall agree, in writing,
to be jointly and severally liable with Tenant for rent and performance of all
of the terms, covenants, and conditions of such approved sublease.

     16.  SIGNS.  Tenant shall not inscribe any inscription, or post, place, or
in any manner display any sign, graphics, notice, picture, placard or poster, or
any advertising matter whatsoever, anywhere in or about the Property at places
visible (either directly or indirectly as an outline or shadow on a glass pane)
from anywhere outside the Premises without first obtaining Landlord's written
consent, such consent to be at Landlord's sole discretion.  Any such consent by
Landlord shall be upon the understanding and condition that Tenant shall remove
the same at the expiration or sooner termination of this Lease and Tenant, at
its expense, shall repair any damage to the Property, or any portion thereof,
caused by such removal.  Notwithstanding the foregoing, Tenant is permitted to
place signage on the Building in a location that is acceptable on the East
facade of the building.  Tenant will also be permitted to place their name on a
monument sign to be constructed at the main entrance to the property.   Such
signage must be pre-approved by Landlord's architect and must comply with local
laws.  The cost of such signage, maintenance, repair and operation shall be
borne exclusively by Tenant.

     17.  LIENS.  Tenant shall keep its interest in this Lease, any property of
Tenant located on the Property (other than the unattached personal property set
forth on Exhibit C-1), and the Property free from any liens arising out of any
work performed or materials ordered or obligations incurred by or on behalf of
Tenant and Tenant hereby agrees to indemnify, defend and hold Landlord harmless
from and against any liability from any such lien, including without limitation,
liens arising from Tenant's Work.  In the event any lien is filed against the
Property, or any portion thereof, by any person claiming by, through or under
Tenant, Tenant shall, upon request of Landlord and at Tenant's expense,
immediately either cause such lien to be released of record or furnish to
Landlord a bond, in form and amount and issued by a surety, satisfactory to
Landlord, indemnifying Landlord and the Property against all liability, costs
and expenses, including attorneys' fees, which Landlord may incur as a result
thereof.  Provided that such bond has been furnished to Landlord, Tenant, at its
sole cost and expense and after written notice to Landlord, may contest, by
appropriate proceedings conducted in good faith and with due diligence, any
lien, encumbrance or charge against the Property arising from work done or
materials provided to and for Tenant, if, and only if, such proceedings suspend
the collection thereof against Landlord, Tenant and the Property and neither the
Property nor any part thereof or interest therein is or will be in any danger of
being sold, forfeited or lost.

     18.  BANKRUPTCY.

          18.1 ASSUMPTION OF LEASE.  In the event Tenant becomes a Debtor under
Chapter 7 of the Bankruptcy Code ("Code") or a petition for reorganization or
adjustment of debts is filed concerning Tenant under Chapters 11 or 13 of the
Code, or a proceeding is filed under Chapter 7 of the Code and is transferred to
Chapters 11 or 13 of the Code, the Trustee or Tenant, as Debtor and as Debtor-
In-Possession, may not elect to assume this Lease unless, at the time of such
assumption, the Trustee or Tenant has:  (i) Cured all defaults under the Lease
and paid all sums due and owing under the Lease or provided Landlord with
"Adequate Assurance" (as defined below) that:  (i) within ten (10) days from the
date of such assumption, the Trustee or Tenant will completely pay all sums due
and owing under this Lease and compensate Landlord for any actual pecuniary loss
resulting from any existing default or breach of this Lease, including without
limitation, Landlord's reasonable costs, expenses, accrued interest, and
attorneys' fees incurred as a result of the default or breach; (ii) within
twenty (20) days from the date of such assumption, the Trustee or Tenant will
cure all non-monetary defaults and breaches under this Lease, or, if the nature
of such non-monetary defaults is such that more than twenty (20) days are
reasonably required for such cure, that the Trustee or Tenant will commence to
cure such non-monetary defaults within twenty (20) days and thereafter
diligently prosecute such cure to completion; and (iii) the assumption will be
subject to all of the provisions of this Lease.

               18.1.1    DEFINITION OF ADEQUATE ASSURANCES. For purposes of this

                                      17
<PAGE>
 
Section 18, Landlord and Tenant acknowledge that in the context of a bankruptcy
proceeding involving Tenant, at a minimum, "Adequate Assurance" shall mean:  (i)
the Trustee or Tenant has and will continue to have sufficient unencumbered
assets after the payment of all secured obligations and administrative expenses
to assure Landlord that the Trustee or Tenant will have sufficient funds to
fulfill the obligations of Tenant under this Lease; and (ii) the Bankruptcy
Court shall have entered an Order segregating sufficient cash payable to
Landlord and/or the Trustee or Tenant shall have granted a valid and perfected
first lien and security interest and/or mortgage in or on property of Trustee or
Tenant acceptable as to value and kind to Landlord, to secure to Landlord the
obligation of the Trustee or Tenant to cure the monetary and/or non-monetary
defaults and breaches under this Lease within the time periods set forth above;
and (iii) the Trustee or Tenant, at the very minimum, shall deposit a sum equal
to 2 month's Base Rent to be held by Landlord (without any allowance for
interest thereon) to secure Tenant's future performance under the Lease.

          18.2 ASSIGNMENT OF LEASE.  If the Trustee or Tenant has assumed the
Lease pursuant to the provisions of this Section 18 for the purpose of assigning
Tenant's interest hereunder to any other person or entity, such interest may be
assigned only after the Trustee, Tenant or the proposed assignee have complied
with all of the terms, covenants and conditions of this Lease, including,
without limitation, those with respect to Additional Rent. Landlord and Tenant
acknowledge that such terms, covenants and conditions are commercially
reasonable in the context of a bankruptcy proceeding of Tenant.  Any person or
entity to which this Lease is assigned pursuant to the provisions of the Code
shall be deemed without further act or deed to have assumed all of the
obligations arising under this Lease on and after the date of such assignment.
Any such assignee shall upon request execute and deliver to Landlord an
instrument confirming such assignment.

          18.3 ADEQUATE PROTECTION. Upon the filing of a petition by or against
Tenant under the Code, Tenant, as Debtor and as Debtor-In-Possession, and any
Trustee who may be appointed agree to adequately protect Landlord as follows:
(i) to perform each and every obligation of Tenant under this Lease until such
time as this Lease is either rejected or assumed by Order of the Bankruptcy
Court; (ii) to pay all monetary obligations required under this Lease, including
without limitation, payment of Rent and Additional Rent payable hereunder which
is considered reasonable compensation for the use and occupancy of the Premises;
(iii) provide Landlord a minimum of thirty (30) days prior written notice,
unless a shorter period is agreed to in writing by the parties, of any
proceeding relating to any assumption of this Lease or any intent to abandon the
Premises, which abandonment shall be deemed a rejection of this Lease; and (iv)
to perform to the benefit of Landlord as otherwise required under the Code. The
failure of Tenant to comply with the above shall result in an automatic
rejection of this Lease.

     19.  DEFAULT.

          19.1 CUMULATIVE REMEDIES.  All rights of Landlord in this Lease shall
be cumulative, and none shall exclude any other right or remedy allowed by law
in force when the default occurs or in equity.  In addition to the other
remedies provided in this Lease, Landlord shall be entitled to restrain by
injunction (without bond) the violation or attempted violation of any of the
covenants, agreements or conditions of Tenant under this Lease.

          19.2 TENANT'S DEFAULT; RIGHT TO CURE. The failure of Tenant to perform
any obligation of Tenant as provided in this Lease shall be a default under this
Lease. Tenant shall have a period of five (5) business days from the date of
Tenant's receipt of written notice from Landlord to Tenant within which to cure
any default in the payment of Rent or Additional Rent. Tenant shall have a
period of ten (10) business days from the date of written notice from Landlord
to Tenant to cure any other default under this Lease; provided, however, that
with respect to any such default which cannot be cured within such ten (10) day
period, the default shall not be deemed to be uncured if Tenant commences to
cure within ten (10) days and for so long as Tenant is diligently prosecuting
the cure thereof.

          19.3 LANDLORD'S RIGHTS AND REMEDIES. Upon the occurrence of an uncured
default by Tenant, Landlord, in addition to all other rights or remedies it may
have, at its option, may exercise any of the following rights without further
notice or demand of any kind to Tenant 

                                      18
<PAGE>
 
or any other person, except as required by applicable State law:

               19.3.1    TERMINATION OF LEASE. The right of Landlord to
terminate this Lease and Tenant's right to possess the Premises and to reenter
the Premises, take possession thereof and remove all person from the Premises,
following which Tenant shall have no further claim thereon or hereunder;

               19.3.2    RE-ENTRY OF THE PREMISES. The right of Landlord,
without terminating this Lease and Tenant's right to possess the Premises, to
reenter the Premises and occupy the whole or any part of the Premises for and on
account of Tenant
and to collect any unpaid Rents which have become payable, or which may
thereafter become payable; or

               19.3.3    TERMINATION AFTER REENTRY.  The right of Landlord, even
though it may have reentered the Premises in accordance with Section 19.3.2, to
elect thereafter to terminate this Lease and Tenant's right to possess the
Premises.

     Should Landlord reenter the Premises under Section 19.3.2, Landlord shall
not be deemed to have terminated this Lease or to have accepted a surrender
thereof by any such reentry, unless Landlord shall have notified Tenant in
writing that it has so elected to terminate this Lease and Tenant's right of
possession.  Tenant further covenants that Landlord's service of any notice
pursuant to the unlawful detainer statutes of the State of Washington and
Tenant's surrender of possession pursuant to such notice shall not (unless
Landlord elects to the contrary at the time of, or at any time subsequent to,
the serving of such notice and such election is evidenced by a notice to Tenant)
be deemed to be a termination of this Lease.  In the event of any reentry or
taking of possession of the Premises as provided above in this Section 19,
Landlord shall have the right, but not the obligation, to remove from the
Premises all or any part of Tenant's property located in the Premises and to
place such property in storage at a public warehouse at the expense and risk of
Tenant.

          19.4 LANDLORD'S DAMAGES. If Landlord terminates this Lease and
Tenant's right to possession of the Premises pursuant to the terms of this
Section 19, Landlord may recover from Tenant as damages, all of the following:

               19.4.1    DELINQUENT RENT. The worth at the time of award of any
unpaid Rent earned at the time of such termination;

               19.4.2    RENT AFTER TERMINATION UNTIL JUDGMENT. The worth at the
time of award of the amount by which the unpaid Rent that would have been earned
after termination until the time of award exceeds such rent loss that Tenant
proves could have been reasonably avoided;

               19.4.3    RENT AFTER JUDGMENT.  The worth at the time of award of
the amount by which the unpaid Rent for the balance of the Lease Term after the
time of award exceeds the amount of such rent loss that Tenant proves could be
reasonably avoided;

               19.4.4    LEASING CONCESSIONS.  The unamortized portion of any
financial concessions incurred by Landlord on Tenant's behalf to arrange for
Tenant's leasing of the Premises that Landlord conditionally waived at the
commencement of the Lease in consideration of Tenant's full performance of this
Lease, but which upon termination of the Lease pursuant to this Section 19 shall
accrue as rent, which costs include, but are not limited to, leasing
commissions, tenant allowances and improvements (including without limitation,
the cost of any improvements to the Premises by Landlord pursuant to Exhibit C),
"free rent" allowances and other such concessions in this Lease, amortized on a
straight-line basis over the number of months during the Lease Term in which
Tenant is obligated to pay Base Rent, and such amounts shall become immediately
due and payable as Rent earned at the time of such termination of the Lease;

               19.4.5    OTHER COMPENSATION.  Any other amount necessary to
compensate Landlord for all the detriment proximately caused by Tenant's failure
to perform its 

                                      19
<PAGE>
 
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including, without limitation, any cost or expense
incurred by Landlord in (i) retaking possession of the Premises, including
reasonable attorney fees therefor, (ii) maintaining or preserving the Premises
after such default, (iii) preparing the Premises for reletting to a new tenant,
including repairs necessary to the Premises for such reletting, (iv) leasing
commissions, limited to those years remaining in the initial term, and (v) any
other costs necessary or appropriate to relet the Premises; and

                19.4.6    ADDITIONAL OR ALTERNATIVE DAMAGES. At Landlord's
election, such other amounts in addition to or in lieu of the foregoing in this
Section 19.4 as may be permitted from time to time by the laws of the State of
Washington; and

                19.4.7    CALCULATION OF DAMAGES. As used in Sections 19.4.1 and
19.4.2, the "worth at the time of award" is to be computed by allowing interest
at the rate specified in Section 4.2. As used in Section 19.4.3, the "worth at
the time of award" is computed by discounting such amount at a discount rate
equal to six percent (6%) per year or the maximum rate allowed by any usury or
similar law, if any, of the State of Washington applicable to Tenant, whichever
is less. All Rent, other than Base Rent, shall, for the purposes of calculating
any amount due under the provisions of Section 19.4.3 be computed on the basis
of the average monthly amount thereof accruing during the immediately preceding
sixty (60) month period, except that if it becomes necessary to compute such
rent before such a sixty (60) month period has occurred, then such rent shall be
computed on the basis of the average monthly amount hereof accruing during such
shorter period.

          19.5  FIXTURES.  Without limiting any of Landlord's rights under this
Lease, in the event of Tenant's default, Tenant's property specified on Exhibit
C-l and any other property which pursuant to the terms of this Lease may be
removed by Tenant at the termination of this Lease shall (i) remain on the
Premises and continuing during the length of such default Landlord shall have
the right to take the exclusive possession of such property and to use such
property free of rent or charge until all defaults have been cured, (ii) be
removed by Landlord from the Premises and placed in storage at a public
warehouse at the expense and risk of Tenant, or (iii) be removed by Tenant upon
demand by Landlord.

          19.6  NO WAIVER.  The waiver by Landlord of any breach of any term,
covenant or condition contained in this Lease shall not be deemed to be a waiver
of such term, covenant or condition or any subsequent breach thereof, or of any
other term, covenant or condition contained in this Lease.  Landlord's
subsequent acceptance of partial rent or performance by Tenant shall not be
deemed to be an accord and satisfaction or a waiver of any preceding breach by
Tenant of any term, covenant or condition of this Lease or of any right of
Landlord to a forfeiture of the Lease by reason of such breach, regardless of
Landlord's knowledge of such preceding breach at the time of Landlord's
acceptance.  No term, covenant or condition of this Lease shall be deemed to
have been waived by Landlord unless such waiver is in writing and signed by
Landlord.

          19.7  WAIVER OF NOTICE.  Notwithstanding anything to the contrary in
this Section 19, Tenant waives (to the fullest extent permitted under law) any
written notice, other than such notice as this Section 19 or any other provision
of this Lease specifically requires, which any statute or law now or hereafter
in force prescribes be given Tenant.

          19.8  WAIVER OF REDEMPTION RIGHTS.  Tenant, for itself, and on behalf
of any and all persons claiming through or under it, including creditors of all
kinds, does hereby waive and surrender all right and privilege which they or any
of them might have under or by reason of any present or future law, to redeem
the Premises or to have a continuance of this Lease for the term hereof, as it
may have been extended, after having been dispossessed or ejected therefrom by
process of law or under the terms of this Lease or after the termination of this
Lease as herein provided.

          19.9  DEFAULT BY LANDLORD.  Landlord shall not be in default unless
Landlord fails to perform obligations required of Landlord within a reasonable
time, but in no event later than thirty (30) days after written notice by Tenant
to Landlord and any mortgagee whose name 

                                      20
<PAGE>
 
and address has been provided to Tenant in writing ("Mortgagee"); provided,
however, that if the nature of Landlord's obligation is such that more than
thirty (30) days are required for performance, then Landlord shall not be in
default if Landlord commences performance within such 30-day period and
thereafter diligently prosecutes the same to completion. Any mortgagee may also
cure such default within the above time period. If Landlord fails to cure any
such default within the allotted time, Tenant may, with reasonable written
notice, undertake cure of such default itself and Landlord shall pay the
reasonable cost thereof on demand.

      20. SUBORDINATION AND ATTORNMENT.  This Lease shall be subordinate to any
mortgage or deed of trust now existing or hereafter placed upon the Land, the
Building or the Premises, created by or at the instance of Landlord, and to any
and all advances to be made thereunder and to interest thereon and all
modifications, renewals and replacements or extensions thereof ("Landlord's
Mortgage"); provided, however, that the holder of any Landlord's Mortgage or any
person or persons purchasing or otherwise acquiring the Land, Building or
Premises at any sale or other proceeding under any Landlord's Mortgage may elect
to continue this Lease in full force and effect and, in such event, Tenant shall
attorn to such person or persons.  Notwithstanding the foregoing, if a lender
requires that the Lease be subordinate to any mortgage recorded after the date
the Lease affecting the Property, the Lease shall be subordinate to such
mortgage if Landlord first obtains from such lender a written statement
providing that so long as Tenant performs its obligations under the Lease, no
foreclosure of, deed given in lieu of foreclosure of, or sale under the
mortgage, and no steps or procedures, taken under the mortgage, shall affect
Tenant's rights under this Lease. Tenant shall execute, acknowledge and deliver
documents which the Holder of any Landlord's Mortgage may require to effectuate
the provisions of this Section 20 within ten (10) days of the date of Landlord's
request therefor.  In the event of any transfer of Landlord's interest in the
Premises or in the Property, other than a transfer for security purposes only,
the transferor shall be automatically relieved of any and all obligations and
liabilities on the part of Landlord accruing from and after the date of such
transfer and such transferee shall have no obligation or liability with respect
to any matter occurring or arising prior to the date of such transfer.  Tenant
agrees to attorn to such transferee, provided transferee assumes all of
Landlord's responsibilities.

      21. REMOVAL OF PROPERTY.  Subject to Section 19.5, upon the expiration or
sooner termination of the Lease, Tenant shall remove Tenant's personal property
not permanently affixed to the Premises and as specified on Exhibit C-1, and
shall pay Landlord any damages for injury to the Premises or Property resulting
from such removal.  If Tenant fails to remove any such property from the
Premises at the termination of this Lease or when Landlord has the right of re-
entry, Landlord may remove and store said property without liability for loss
thereof or damage thereto, provided Landlord uses commercially reasonable
standards in performance of such removal rights.   Such storage shall be for the
account and at the expense of Tenant.  If Tenant fails to pay the cost of
storing any such property after it has been stored for a period of thirty (30)
days or more, Landlord may, at its option, sell, or permit to be sold, any or
all such property at public or private sale, in such manner and at such times
and places as Landlord in its sole discretion may deem proper, without notice to
Tenant, unless notice is required under applicable statutes, and shall apply the
proceeds of such sale first, to the cost and expense of such sale, including
reasonable attorneys' fees actually incurred; second, to the payment of the
costs or charges for storing any such property; third, to the payment of any
other sums of money which may then be or thereafter become due Landlord from
Tenant under any of the terms of this Lease; and, fourth, the balance, if any,
shall be paid to Tenant.

      22. CONDEMNATION.

          22.1  ENTIRE TAKING.  If all of the Premises, or such portion of the
Building as may be required for the reasonable use of the Premises, in
Landlord's determination, are taken by eminent domain, this Lease shall
automatically terminate as of the date title vests in the condemning authority
and all Rent, Additional Rent and other payments shall be paid to that date.

          22.2  CONSTRUCTIVE TAKING OF ENTIRE PREMISES.  In the event of a
taking by eminent domain of a material part of but less than all of the
Building, if Landlord determines that 

                                      21
<PAGE>
 
the remaining portions of the Building cannot be economically and effectively
used by it (whether on account of physical, economic, aesthetic or other
reasons) or if Landlord determines the Building should be restored in such a way
as to materially alter the Premises, then Landlord shall forward a written
notice to Tenant of such determination not more than sixty (60) days after the
date of taking. The term of this Lease shall expire upon the date specified by
Landlord in such notice but not earlier than sixty (60) days after the date of
such notice.

          22.3  PARTIAL TAKING.  Subject to the provisions of the preceding
Section 22.2, in case of taking by eminent domain of a part of the Premises, or
a portion of the Building not required for the reasonable use of the Premises,
then this Lease shall continue in full force and effect and the Rent shall be
equitably reduced based on the proportion by which the floor area of the
Premises is reduced, such Rent reduction to be effective as of the date title to
such portion vests in the condemning authority.  If more than twenty-five
percent (25%) of the Premises is taken and Landlord cannot replace such space
with space in the Building which is mutually acceptable to Landlord and Tenant,
then with sixty (60) days written notice by either party, Landlord or Tenant
shall have the right to terminate this Lease.

          22.4  AWARDS AND DAMAGES.  Landlord reserves all rights to damages to
the Premises for any partial, constructive, or entire taking by eminent domain,
and Tenant hereby assigns to Landlord any right Tenant may have to such damages
or award, and Tenant shall make no claim against Landlord or the condemning
authority for damages for termination of the leasehold interest or interference
with Tenant's business.  Tenant shall have the right, however, to claim and
recover from the condemning authority compensation for any loss to which Tenant
may be put for Tenant's moving expenses, business interruption, loss of
goodwill, or taking of Tenant's personal property (not including Tenant's
leasehold interest) provided that such damages may be claimed only if they are
awarded separately in the eminent domain proceedings and not out of or as part
of the damages recoverable by Landlord.

      23. NOTICES.  All notices under this Lease shall be in writing and
delivered in person or sent by registered or certified mail, postage prepaid, or
by facsimile, to Landlord and to Tenant at their respective Notice Addresses set
forth in Section 1.16 (provided that after the Commencement Date any such notice
shall be mailed, delivered by hand or transmitted by facsimile to Tenant at the
Premises) or such other addresses as may from time to time be designated by any
such party in writing.  Notices mailed as provided in this Section shall be
deemed given and received on the date that is Three (3) business days following
the date of post mark, in the case of mailing, or the date of transmission
confirmation by the sender's facsimile machine, in the case of facsimile
transmission.

      24. COSTS AND ATTORNEYS' FEES.  If Tenant or Landlord  bring any action
for any relief against the other, declaratory or otherwise, arising out of this
Lease, each party shall, and hereby does to the extent permitted by law, waive
trial by jury and the losing party shall pay the substantially prevailing
party's attorneys' fees in connection with such suit, at trial and on appeal,
and such attorneys' fees shall be deemed to have accrued on the commencement of
such action.

      25. LANDLORD'S LIABILITY.  Notwithstanding anything in this Lease to the
contrary, covenants, undertakings and agreements herein made on the part of
Landlord in this Lease are made and intended not as personal covenants,
undertakings and agreements for the purpose of binding Landlord personally or
the assets of Landlord except Landlord's interest in the Premises and Building
and rents and proceeds thereof, but are made and intended for the purpose of
binding only the Landlord's interest in the Premises and Building, as the same
may from time to time be encumbered.  No personal liability or personal
responsibility is assumed by Landlord, nor shall at any time be asserted or
enforceable against Landlord or its heirs, legal representatives, successors or
assigns on account of the Lease or on account of any covenant, undertaking or
agreement of Landlord in this Lease.

      26. LANDLORD'S CONSENT.  Except as may be provided otherwise in this
Lease, whenever Landlord's consent is required under this Lease, such consent
shall not be unreasonably withheld, conditioned or delayed, provided, however,
Landlord's withholding of consent due to any mortgagee's refusal to grant its
consent shall not be deemed unreasonable.

                                      22
<PAGE>
 
      27. ESTOPPEL CERTIFICATES.  Tenant shall, from time to time upon the
written request of Landlord, execute, acknowledge and deliver to Landlord or its
designee a written statement stating:  the Effective Date, Commencement Date and
Expiration Date, the date the term commenced and the date Tenant accepted the
Premises; the amount of Base Rent and the date to which such Base Rent has been
paid; and certifying such additional information as may be requested by
Landlord.  It is intended that any such statement delivered pursuant to this
Section may be relied upon by a prospective purchaser of Landlord's interest or
assignee of any mortgage upon Landlord's interest in the Building.  If Tenant
shall fail to respond within ten (10) days of receipt by Tenant of a written
request by Landlord as herein provided, Tenant shall be deemed to have given
such certificate as above provided without modification and shall be deemed to
have admitted the accuracy of any information supplied by Landlord to a
prospective purchaser or mortgagee and to have certified that this Lease is in
full force and effect, that this Lease represents the entire agreement between
the parties as to this leasing, that there are no existing claims, defenses or
offsets which Tenant has against enforcement of the Lease by Landlord, that
there are no uncured defaults in Landlord's performance, that the security
deposit is as stated in the Lease, and that not more than one month's Base Rent
or Additional Rent has been paid in advance.

      28. RIGHT TO PERFORM.  If Tenant fails to pay any sum of money required to
be paid by it under this Lease or fails to perform any other act on its part to
be performed under this Lease, and such failure continues for ten (10) days
after notice thereof by Landlord, Landlord may, but shall not be obligated so to
do, and without waiving or releasing Tenant from any obligations of Tenant, make
such payment or perform any such other act on Tenant's part to be made or
performed as provided in this Lease.  Landlord shall have (in addition to any
other right or remedy of Landlord) the same rights and remedies in the event of
the nonpayment of sums due under this Section 28 as in the case of default by
Tenant in the payment of Rent.

      29. PARKING.  Landlord shall provide, at no cost to Tenant for the term of
this Lease, Tenant twenty-five (25) unassigned and five (5) assigned parking
stalls in the parking area(s) servicing the Building, as outlined on Exhibit E.
The assigned parking stalls will be in a mutually agreeable location near the
Tenant's entrance and shall be identified as Tenant's spaces.  The provision of
parking stalls under this Lease shall be subject to such rules and regulations
as Landlord and/or Landlord's parking operator may adopt from time to time.
Landlord retains the right to alter such rules and regulations and to relocate
within the area as outlined on Exhibit E, or reconfigure the parking area in
which Tenant's parking stalls are located, with reasonable notice to Tenant, but
Landlord shall at all times continue to provide the designated number of spaces
to Tenant.  Tenant shall pay, upon demand by Landlord, Landlord's costs incurred
to stencil any changes to reserved parking stalls provided to Tenant under this
Lease.

      30. AUTHORITY.  If Tenant is a corporation, each individual executing this
Lease on behalf of Tenant represents and warrants that he or she is duly
authorized to execute and deliver this Lease on behalf of Tenant, in accordance
with a duly adopted resolution of the Board of Directors of Tenant and in
accordance with the bylaws of Tenant, and that this Lease is binding upon Tenant
in accordance with its terms.  If Tenant is a partnership, each individual
executing this Lease on behalf of Tenant represents and warrants that he or she
is duly authorized to execute and deliver this Lease on behalf of Tenant, in
accordance with the partnership agreement of Tenant, and that this Lease is
binding upon Tenant in accordance with its terms.

      31. GENERAL.

          31.1  HEADINGS.  Titles to Sections of this Lease are not a part of
this Lease and shall have no effect upon the construction or interpretation of
this Lease.

          31.2  HEIRS AND ASSIGNS.  All of the covenants, agreements, terms and
conditions contained in this Lease shall inure to and be binding upon the
Landlord and Tenant and their respective heirs, executors, administrators,
successors and assigns.

          31.3  NO BROKERS.  Except as provided in Section 1, Landlord and
Tenant represent and warrant to one another that they have not engaged any
broker, finder or other 

                                      23
<PAGE>
 
person who would be entitled to any commission or fees in respect of the
negotiation, execution or delivery of this Lease and Landlord and Tenant shall
indemnify and hold one another harmless from and against any loss, cost,
liability or expense incurred by the other party as a result of any claim
asserted by any such broker, finder or other person on the basis of any
arrangements or agreements made or alleged to have been made by or on behalf of
Tenant.

          31.4  ENTIRE AGREEMENT.  This Lease contains all covenants and
agreements between Landlord and Tenant relating in any manner to the leasing,
use and occupancy of the Premises, to Tenant's use of the Building and other
matters set forth in this Lease.  No prior agreements or understanding
pertaining to the same shall be valid or of any force or effect and the
covenants and agreements of this Lease shall not be altered, modified or added
to except in writing signed by Landlord and Tenant.

          31.5  SEVERABILITY.  Any provision of this Lease which shall prove to
be invalid, void or illegal shall in no way affect, impair or invalidate any
other provision hereof and the remaining provisions hereof shall nevertheless
remain in full force and effect.

          31.6  FORCE MAJEURE.  Except for the payment of Rent,  time periods
for Tenant's or Landlord's performance under any provisions of this Lease shall
be extended for periods of time during which Tenant's or Landlord's performance
is prevented due to circumstances beyond Tenant's or Landlord's respective
control, including without limitation, strikes, embargoes, shortages of labor or
materials, governmental regulations, acts of God, war or other strife.

          31.7  RIGHT TO CHANGE PUBLIC SPACES.  Landlord shall have the right at
any time without thereby creating an actual or constructive eviction or
incurring any liability to Tenant therefor, to change the arrangement or
location of such of the following as are not contained within the Premises or
any part thereof:  entrances, passageways, doors and doorways, corridors,
stairs, toilets and other public portions of the Property.  In no event,
however, shall Landlord diminish any service provided by Landlord under this
Lease, make any change which reduces the area of the Premises, make any change
which, on other than a temporary basis, either changes the character of the
Building from that of an office building or materially interferes with Tenant's
access to and use of the Building.

          31.8  GOVERNING LAW.  This Lease shall be governed by and construed in
accordance with the laws of the State of Washington.

          31.9  BUILDING DIRECTORY.  In the event Landlord maintains in the
lobby of Building a directory of tenants, such directory shall include the name
of Tenant and any other names reasonably requested by Tenant in proportion to
the number of listings given to comparable tenants of the Building.  Tenant will
also be required to provide suite signage consistent with the Building standard
or subject to Landlord's architects' approval.

          31.10 BUILDING NAME.  The Building will be known as Riverfront
Technical Park or by such name as Landlord may designate from time to time.

          31.11 QUIET ENJOYMENT.  Landlord agrees that Tenant, upon paying the
Rent and performing all other terms, covenants and conditions of this Lease to
be performed by Tenant, may quietly have, hold and enjoy the Premises from and
after the Commencement Date until the Expiration Date, subject, however, to the
provisions of Section 11 (Damage Or Destruction), 22 (Condemnation), and to any
sale or Landlord's Mortgage to which this Lease is, or may become, subordinate.

          31.12 SURVIVAL.  The representations, warranties and indemnification
obligations of the parties to this Lease shall survive the termination or
expiration of this Lease.

 
     IN WITNESS WHEREOF this Lease has been executed the day and year first
above set forth.

                       LANDLORD'S WORK AND TENANT'S WORK

I.    IMPROVEMENTS PROVIDED BY LANDLORD

      Landlord's Work to the Premises shall consist of the following:

1.  Build any new demising walls surrounding the Premises, and any common area
corridor necessitated by the location of Exodus in the building.

2.  Make available 1,200 amps of connected load electrical service for the
discretionary use of Exodus.

3.  Landlord will make available an adequate amount of rooftop space and access
to the roof for the installation of satellite dishes, antenna and other forms of
communications equipment at Tenant's sole expense and maintenance.

4.  Landlord will make a second location available for a backup generator.  The
location will be in a mutually agreeable location to both Tenant and Landlord,
and will comply with all rules and regulations from the City of Tukwila for
screening.  The Tenant will be responsible for all costs associated with said
generator, including the payment for any parking which may be removed to
accommodate the generator.

      Except for such Landlord's Work, Landlord shall deliver, and Tenant shall
accept (except as provided for in Section IV. G. below), the Premises in its
"AS-IS" condition and configuration as provided in the Lease.  Without limiting
the foregoing, Landlord shall not be required to modify or improve the existing
heating, exhaust, ventilation or air-conditioning equipment, to reinforce or
level the flooring of the Premises or the existing electrical system, to
accommodate Tenant.

II.   IMPROVEMENTS BY TENANT/CONSTRUCTED BY LANDLORD'S CONTRACTOR

      Design and construction of all improvements in the Premises beyond
Landlord's Work listed in Section I of this Exhibit C shall be provided at
Tenant's expense, subject to Landlord's payment of the Tenant Allowance if any.

III.  BUILDING STANDARD IMPROVEMENTS

      Landlord will choose the contractor to do Landlord Improvements if any.

IV.   CONSTRUCTION OF TENANT IMPROVEMENTS

      A.   AUTHORIZATION TO PROCEED.  Upon completion of Tenant's Final Plans,
Landlord shall provide to Tenant written notice of the price for such
improvements.  Within five (5) days of receipt of such price, Tenant shall give
Landlord written authorization to complete the Premises in accordance with such
Final Plans.  Tenant may in such authorization delete any or all items of extra
cost; however, if Landlord deems these changes to be extensive, at it option,
Landlord may refuse to accept the authorization to proceed until all changes
have been incorporated in the Final Plans signed by Tenant and written
acceptance of the revised price has been received by Landlord from Tenant.  In
the absence of such written authorization to proceed, Landlord shall not be
obligated to commence work on the Premises and Tenant shall be responsible for
any costs due to any resulting delay in completion of the Premises.

      B.   PAYMENTS.  Landlord's contractor shall complete Tenant's improvements
if chosen to do so in accordance with Tenant's approved Final Plans.  Tenant
shall pay, within ten (10) 

                                      C-1
<PAGE>
 
days after receipt of monthly progress statements from Landlord, the full amount
of such progress billing. Tenant may retain an amount equal to five percent (5%)
of the estimated cost of such improvements from the last payment due before

                  hereof, the Tenant shall remain in possession without any
                  further written agreement or in circumstances where a tenancy
                  would thereby be created by implication of law or otherwise, a
                  tenancy from year to year shall not be created by implication
                  of law or otherwise, but the Tenant shall be deemed to be a

                  Tenant in payment of such monthly Rent. The Tenant hereby
                  agrees to indemnify, defend and hold Landlord, the Leased

                  excluding any consequential or punitive damages claimed by
                  Landlord) which the Landlord may suffer as a result of the
                  Tenant's failure to timely surrender exclusive possession of
                  the Leased Premises to Landlord, as set forth herein.

Payment-          (c)    Additional Rent shall be paid and adjusted with 
Additional        reference to a fiscal period of twelve (12) calendar months 
Rent              ("Fiscal Period"), which shall be a calendar year unless the
                  Landlord shall from time to time have selected a Fiscal Period
                  which is not a calendar year by written notice to the Tenant.

                         The Landlord shall advise the Tenant in writing of its
                  estimate of the Additional Rent to be payable by the Tenant
                  during the Fiscal Period (or broken portion of the Fiscal
                  Period, as the case may be, if applicable at the Commencement
                  Date or because of a change in Fiscal Period) which commenced
                  upon the Commencement Date and for each succeeding Fiscal
                  Period or broken portion thereof which commences during the
                  Term. Such estimate shall in every case be a reasonable
                  estimate and, if requested by the Tenant, shall be accompanied
                  by reasonable particulars of the manner in which it was
                  calculated. The Additional Rent payable by the Tenant shall be
                  paid in equal monthly installments in advance at the same time
                  as payment of Basic Rent is due hereunder based on the
                  Landlord's estimate as aforesaid. From time to time, the
                  Landlord may re-estimate, on a reasonable basis, the amount of
                  Additional Rent for any Fiscal Period or broken portion
                  thereof, in which case the Landlord shall advise the Tenant in
                  writing of such re-estimate and fix new equal monthly
                  installments for the remaining balance of such Fiscal Period
                  or broken portion thereof. After the end of each such Fiscal
                  Period or broken portion thereof the Landlord shall submit to
                  the Tenant a statement of the actual Additional Rent payable
                  in respect of such Fiscal Period or broken portion thereof and
                  a calculation of the amounts by which the Additional Rent
                  payable by the Tenant exceeds or is less than (as the case may
                  be) the aggregate installments paid by the Tenant on account
                  of Additional Rent for such Fiscal Period. Within thirty (30)
                  days after the submission of such statement either the Tenant
                  shall pay to the Landlord any amount by which the amount found
                  payable by the Tenant with respect to such Fiscal Period or
                  broken portion thereof exceeds the aggregate of the monthly
                  payments made by it on account thereof during such Fiscal
                  Period or broken portion thereof, or the Landlord shall pay to
                  the Tenant any amount by which the amount found payable as
                  aforesaid is less than the aggregate of such monthly payments.

Accrual of        (d)  Basic Rent and Additional Rent (herein collectively 
Rent              called "Rent") shall be considered as accruing from day to
                  day, and Rent for an irregular period of less than one year or
                  less than one calendar month shall be apportioned and

                  cannot be made until after the termination of this Lease, the
                  obligation of the Tenant to pay Additional Rent shall survive
                  the termination hereof and Additional Rent for such period
                  shall be payable by the Tenant upon demand by the Landlord. If
                  the Term commences or expires on any day other than the first
                  or the last day of a month, Rent for such fraction of a month
                  shall be apportioned and adjusted as aforesaid and paid by the
                  Tenant on the actual Commencement Date of the Term.


Recovery of       (e)  Rent and any other amounts required to be paid by the 
Rent              Tenant to the Landlord under this Lease shall be deemed to 
                  be, and will be treated as, Rent, and be payable and
                  recoverable as Rent, and the Landlord shall have all rights
                  against the Tenant for default in any payment of Rent and
                  other amounts as in the case of arrears in Rent.

Limitations       (f) The information set out in statements, documents or other
                  writings setting out the amount of Additional Rent submitted
                  to the Tenant under or pursuant to this Lease shall be binding
                  on the Tenant and deemed to be accepted by it and shall not be
                  subject to amendment for any reason unless the Tenant gives
                  written notice to the Landlord within sixty (60) days of the
                  Landlord's submission of such statement, document, or writing
                  identifying the statement , document, or writing and setting
                  out in reasonable detail the reason why such statement,
                  document or writing should not be binding on the Tenant.
                  However, and within the sixty (60) day period provided to the
                  Tenant herein, Tenant shall have the right, after at least
                  five (5) business days' prior written notice to Landlord and
                  only at reasonable times during normal business hours at
                  Landlord's offices in Los Angeles, California, to review
                  Landlord's records pertaining to the calculation of Additional
                  Rent , all at Tenant's sole cost and expense (except as
                  otherwise provided herein). Landlord hereby agrees to use
                  commercially reasonable efforts to cooperate with Tenant in
                  and during such review; provided, Landlord shall not be
                  obligated to expend any monies in connection therewith. If,
                  after such review, Tenant disputes the amount of Additional
                  Rent billed to Tenant, Tenant may retain a reputable,
                  independent, certified public accountancy firm to audit
                  Landlord's records regarding the disputed item or items in
                  order to determine the proper amount of Additional Rent. If
                  such audit reveals that Landlord has overcharged Tenant, then
                  within thirty (30) days after the results of such audit are
                  made available to Landlord, Landlord shall reimburse Tenant
                  for the amount of such overcharge. If the audit reveals that
                  Tenant was undercharged, then within thirty (30) days after
                  the results of such audit are made available to Tenant, Tenant
                  shall reimburse Landlord for the amount of such undercharge.
                  Tenant hereby agrees to pay all costs and expenses associated
                  with any such audit; provided, however, Landlord shall pay
                  such costs and expenses if the audit reveals that Landlord's
                  determination of Additional Rent was in error by more than
                  five percent (5%). Landlord shall use commercially reasonable
                  efforts to maintain the records

                                                                 INITIAL

                  and thereupon shall have no liability to the Tenant to repay
                  the Security Deposit to the Tenant; provided, Landlord will
                  have delivered to Tenant written notice of Landlord's transfer
                  or disposition of all or any portion of Landlord's interest in
                  this Lease. Subject to the foregoing and to the Tenant not
                  being in default under this Lease, the Landlord shall repay

                  or is under common control with, Tenant (collectively, an
                  "Affiliate"), so long as (i) such transaction was not entered
                  into as a subterfuge to avoid the obligations and restrictions
                  of this Lease, (ii) at least ten (10) days prior to the
                  effective date of the transaction, Tenant notifies Landlord of

                  effective date of the assignment or sublease, is at least
                  equal to the net worth of Tenant as of the date of this Lease.
                  Any such assignment or subletting to an Affiliate pursuant to
                  this Paragraph 7 shall neither release nor relieve Tenant from
                  any of Tenant's obligations under this Lease.

Landlord's        (a) The Landlord shall take out and keep in force during the 
insurance         Term insurance with respect to the Property, except for the
                  Leasehold Improvements in the Leased Premises. The insurance
                  to be maintained by the Landlord shall be in respect of perils
                  and to amounts and on terms and conditions which, from time to
                  time, are insurable at a reasonable premium and which are
                  normally insured by reasonable prudent owners of properties
                  similar to the Property, all as from time to time determined
                  at reasonable intervals by insurance advisors selected by the
                  Landlord, and whose opinion shall be conclusive. Unless and
                  until the insurance advisors shall state that any such perils
                  are not customarily insured against by owners of properties
                  similar to the Property, the perils to be insured against by
                  the Landlord shall include, without limitation, public
                  liability, boilers and machinery, fire and extended perils,
                  and may include, at the option of the Landlord, losses
                  suffered by the Landlord through business interruption.
                  Notwithstanding anything to the contrary set forth in this
                  Lease, and without affecting the rights or remedies of the
                  parties hereto, Landlord and Tenant each hereby release and
                  relieve the other, and waive their right to recover damages
                  against each other, for loss of or damage to their respective
                  property arising out of or incident to the perils insured
                  against under this Paragraph 9. The effect of any such
                  releases and waivers is not limited by the amount of insurance
                  carried or by any deductible applicable hereto. Landlord and
                  Tenant hereby agree to have their respective insurance
                  carriers waive any right to subrogation that such carriers may
                  have against either Landlord or Tenant, as the case may be, so
                  long as any insurance is not invalidated thereby.

Tenant's          (b) The Tenant shall take out and keep in force during the    
Insurance         Term:
 

                      (i)  comprehensive Commercial General Liability insurance
                  on an all occurrence basis with respect to Tenant's business
                  carried on, in or from the Leased Premises and the Tenant's
                  use and occupancy of the Leased Premises and any other part of
                  the Property, with coverage for any one occurrence or claim of
                  not less than Two Million Dollars ($2,000,000.00) or such
                  other amount as the Landlord may reasonably require (but not
                  more often than once during each Fiscal Period) upon not less
                  than one (1) month's notice during the Term, which insurance
                  shall include the Landlord as a named insured and shall
                  protect the Landlord in respect of claims by the Tenant as if
                  the Landlord were separately insured;

                      (ii) insurance in respect of fire and such other perils as
                  are from time to time in the usual extended coverage
                  endorsement covering the Leasehold Improvements, trade
                  fixtures, and the furniture and equipment in the Leased
                  Premises for not less than the full replacement cost thereof,
                  and

                                                                 INITIAL

                  which insurance shall include the Landlord as a named insured
                  as the Landlord's interest may appear; and
                   
                         (iii) insurance against such other perils and in such
                  amounts as the Landlord may from time to time reasonably
                  require (but not more often than once during each Fiscal
                  Period) upon not less than ninety (90) days' written notice,
                  such requirement to be made on the basis that the required
                  insurance is customary at the time for prudent tenants of
                  properties similar to the Property.

                  All insurance required to be maintained by the Tenant shall be
                  on terms and with insurers with a General Policy Holders
                  Rating of not less than "A:X" as rated in the most current
                  issue of "Best's Insurance Guide." Each policy shall contain a
                  waiver by the insurer of any rights of subrogation or
                  indemnity or any other claim to which the insurer might
                  otherwise be entitled, as set forth above, and shall also
                  contain an undertaking by the insurer that no material change
                  adverse to the Landlord or the Tenant will be made, and the
                  policy will not lapse or be cancelled, except after not less
                  than thirty (30) days' written notice to the Landlord of the
                  intended change, lapse or cancellation. The Tenant shall
                  furnish to the Landlord, if and whenever requested by it,
                  certificates or other evidence acceptable to the Landlord as
                  to the insurance from time to time effected by the Tenant and
                  its renewal or continuation in force, together with evidence
                  as to the method of determination of full replacement cost of
                  the Tenant's Leasehold Improvements, trade fixtures, furniture
                  and equipment, and if the Landlord reasonably concludes that
                  the full replacement cost has been underestimated, the Tenant
                  shall forthwith arrange for any consequential increase in
                  coverage required under sub-paragraph(b) of this Paragraph 9.
                  If the Tenant shall fail to take out, renew and keep in force
                  such insurance, or if the evidence submitted to the Landlord
                  is unacceptable to the Landlord (or no such evidence is
                  submitted within a reasonable period after request therefor by
                  the Landlord), then the Landlord may give to the Tenant
                  written notice requiring compliance with this sub-paragraph
                  and specifying the respects in which the Tenant is not then in
                  compliance with this sub-paragraph. If the Tenant does not
                  within forty-eight (48) hours provide appropriate evidence of
                  compliance with this subparagraph, the Landlord may (but shall
                  not be obligated to) obtain one or all of the additional
                  coverage or other insurance which the Tenant shall have failed
                  to obtain, without prejudice to any other rights of the
                  Landlord under this Lease or otherwise, and the Tenant shall
                  pay all premiums and other reasonable expenses incurred by the
                  Landlord upon demand. Notwithstanding anything to the contrary
                  set forth in this Paragraph 9(b) and/or elsewhere in this
                  Lease, and in the event that the Tenant fails to obtain and
                  maintain the insurance required under this Paragraph 9 and/or
                  otherwise in this Lease for any reason whatsoever, the Tenant
                  shall be conclusively deemed to have self-insured such
                  insurance obligations with the full waiver of subrogation set
                  forth in Paragraph 9(a) of this Lease; provided, however,
                  nothing contained herein grants to the Tenant the right or
                  option to self-insure the Tenant's

                                                                 INITIAL

                  insurance obligations under this Lease. 

Limitation of     (c)  The Tenant agrees that the Landlord shall not be liable
Landlord's        for any bodily injury or death of, or loss or damage to any 
Liability         property belonging to, the Tenant or its employees, invitees
                  or licensees or any other person in, on or about the Property,
                  unless resulting from the actual willful misconduct or
                  negligence of the Landlord or its own employees. In no event
                  shall the Landlord be liable for any damage which is caused by
                  steam, water, rain or snow or other thing which may leak into,
                  issue or flow from any part of the Property or from the pipes
                  or plumbing works, including the sprinkler system (if any)
                  therein or from any other place or for any damage caused by or
                  attributable to the condition or arrangement of any electric
                  or other wiring or of sprinkler heads (if any) or for any
                  damage caused by anything done or omitted by any other tenant.
                  Notwithstanding anything to the contrary set forth in this
                  Lease, the obligations of the Landlord, and the Landlord's
                  partners (either general or limited), directors, officers and
                  shareholders, under this Lease, do not constitute personal
                  obligations. Tenant, and the Tenant's successors and assigns,
                  hereby agree not to seek any recourse against the personal
                  assets of the Landlord, or the Landlord's partner (either
                  general or limited), directors, officers and shareholders, for
                  the satisfaction of any actual or alleged liability of
                  Landlord to Tenant under this Lease, but Tenant shall look
                  only to the Landlord's interest in the Property for the
                  satisfaction of any liability of Landlord to Tenant hereunder.

Indemnity of      (d)  Except with respect to claims or liabilities in respect
Landlord          of any damage which is Insured Damage to the extent of the
                  cost of repairing such Insured Damage, the Tenant agrees to
                  indemnify, defend (with counsel reasonably acceptable to
                  Landlord) and hold harmless the Landlord and the Property in

                  damage or other loss or damage arising from the conduct of any
                  work or any act or omission of the Tenant or any assignee, 
                  sub-tenant, agent, employee, contractor, invitee or licensee
                  of the Tenant, and in respect of all costs, expenses and
                  liabilities incurred by the Landlord in connection with or

                  or mortgages now or hereafter existing (including charges, and
                  mortgages by way of debenture, note, bond, deeds of trust and
                  mortgage, and all instruments supplemental thereto), which may
                  now or hereafter affect the Property or any part thereof and
                  to all renewals, modifications, consolidations, replacements
                  and extensions thereof provided the lessor, chargee, mortgagee
                  or trustee agrees to accept this Lease if not in default; and
                  in recognition of the foregoing the Tenant agrees that it

                  agreement to be bound by this Paragraph 12, Landlord shall use
                  good-faith efforts and diligence to provide Tenant with a
                  commercially reasonable SNDA from a subsequent ground lessor,
                  mortgage holder or beneficiary under a deed of trust
                  respecting the Property, who later may come into existence
                  during the Term. Tenant hereby expressly waives the provisions
                  of any statute, rule or law which may give or purport to give
                  Tenant the right or election to terminate or otherwise
                  adversely affect this Lease and the obligations of Tenant
                  hereunder solely in the event of any foreclosure proceeding or
                  sale, and Tenant hereby agrees that this Lease shall not be
                  affected in any way whatsoever by any such foreclosure
                  proceeding or sale.

Certificates      13.    The Tenant agrees that it shall, as requested by the
                  Landlord (but not more often then twice during each Fiscal
                  Period), execute and deliver to the Landlord, and if required
                  by the Landlord, to any lessor, chargee, or mortgagee
                  (including any trustee) or other person designated by the
                  Landlord, a reasonable acknowledgment in writing as to the
                  then-status of this Lease, including as to whether it is in

                  pertaining to this Lease as to which the Landlord shall
                  request an acknowledgment.

                  Taking" shall include expropriation and condemnation and shall
                  include a sale by the Landlord to an authority with powers of
                  expropriation, condemnation or taking, in lieu of or under
                  threat of expropriation or taking, and "Publicly Taken" shall
                  have a corresponding meaning. The Tenant hereby waives any and
                  all rights the Tenant might otherwise have pursuant to
                  Sections 1265.110, 1265.120 and 1265.130 of the California

                  such a notice at the Expiration Date or earlier termination of
                  the Term, and in the event of Tenant's failure to so remove or
                  discharge such notice after ten (10) days' written notice by
                  Landlord to Tenant, the Landlord may in the name and on behalf
                  of the Tenant execute a discharge of such a notice in order to
                  remove and discharge such notice and for the purpose thereof

                  the subject matter or context inconsistent therewith; and the
                  parties agree that all of the provisions of this Lease are to
                  be construed as covenants and agreements as though words
                  importing such covenants and agreements were used in each

                  and its remaining provisions shall remain in force and be
                  binding upon the parties hereto as though the said provision
                  or provisions had never been included, and further that the
                  captions appearing for the provisions of this Lease have been

                  Lease shall be construed without regard to any presumption or
                  other rule requiring construction against the party drafting a
                  document and shall be construed neither for nor against either
                  the Landlord or the Tenant, but shall be given a reasonable
                  interpretation in accordance with the plain meaning of its
                  terms and the intent of the parties hereto.

                  notice to the holder of any such lesser estate or interest
                  shall constitute the Landlord's election to have such

                  lesser estate or interest.

Reservations      29.    Landlord reserves to itself the right, from time to
                  time, to grant any such easements, rights, and dedications

                      work. The Landlord shall not unreasonably withhold its
                      approval to any such request, but failure to comply with
                      the Landlord's reasonable requirements from time to time
                      for the Building shall be considered sufficient reason for
                      refusal. In making, erecting, installing or altering any
                      Leasehold Improvements the Tenant shall not, without the
                      prior written approval of the Landlord, alter or interfere
                      with any installations which have been made by the
                      Landlord or others and in no event shall alter or
                      interfere with window coverings (if any) or other light
                      control devices (if any) installed in the Building. The
                      Tenant's request for any approval hereunder shall be in
                      writing and accompanied by an adequate description of the
                      contemplated work and, where appropriate, working drawings
                      and specifications thereof. If the Tenant requires from
                      the Landlord drawings or specifications of the Building in
                      connection with any Leasehold Improvements, the Tenant
                      shall pay the cost thereof to the Landlord on demand. Any
                      reasonable costs and expenses incurred by the Landlord in
                      connection with the Tenant's Leasehold Improvements shall
                      be paid by the Tenant to the Landlord on demand. All work
                      to be performed in the Leased Premises shall be performed
                      by competent contractors and sub-contractors of whom the
                      Landlord shall have approved in writing prior to
                      commencement of any work, such approval not to be
                      unreasonably withheld. All such work, including the
                      deliver, storage and removal of materials, shall be
                      subject to the reasonable supervision of the Landlord,
                      shall be performed in accordance with any reasonable
                      conditions or regulations imposed by the Landlord
                      including, without limitation, payment of Landlord's
                      reasonable out-of-pocket construction supervision fee, and
                      shall be completed in good and workmanlike manner in
                      accordance with the description of the work approved by
                      the Landlord and in accordance with all laws, regulations
                      and by-laws of all regulatory authorities. Copies of
                      required building permits or authorizations shall be
                      obtained by the Tenant at its expense and copies thereof
                      shall be provided to the Landlord. No locks shall be
                      installed on the entrance doors or in any doors in the
                      Leased Premises that are not keyed to the Building's
                      master key system with copies of any keys delivered to
                      Landlord.

                                    expended hereunder or in accordance with
                                    Schedule "G" attached hereto.

                      6.  For the purposes of this Lease, the term "Landlord's
                      Work" shall mean only the following (which shall not be a
                      part of the Leasehold Improvements, and shall immediately
                      upon their placement be and become the Landlord's
                      property):

                            (a)     Landlord will relocate the existing
                                    telephone equipment and telephone room from

                            (b)     Landlord will provide Tenant with a separate

                                    be used by Tenant in the Leased Premises, as
                                    set forth in Schedule "D" attached hereto;
                                                 -----------
                                    and

                            (c)     Landlord will design and construct an
                                    upgrade of the base system for the Building
                                    to provide a new 1,600 amp, 480/277 volt

                            (d)     All of the Landlord's Work shall be
                                    designed, constructed and completed by

                                    wiring related to the Landlord's Work), at
                                    Landlord's sole discretion, and will be
                                    completed by Landlord on or before the
                                    Commencement Date. The Landlord's Work shall

                                    anything to the contrary set forth herein,
                                    as additional consideration for the
                                    performance of Landlord's obligations under
                                    this Lease, Tenant hereby agrees to
                                    reimburse Landlord for a portion of the
                                    total cost of the Electrical Service Upgrade

                                    the Electrical Service Upgrade and the
                                    calculation by Landlord of the total cost of
                                    same (the "Electrical Service Upgrade
                                    Cost"), Landlord hereby agrees to pay the
                                    first Twenty Thousand Dollars (US$20,000.00)
                                    of the Electrical Service Upgrade Cost, and
                                    thereafter, Landlord hereby further agrees
                                    to pay one-half ( 1/2) of the remaining
                                    balance of the Electrical Service Upgrade

                                    the Electrical Service Upgrade Cost will be
                                    payable by Tenant to Landlord, as part of

                                    of ten percent (10%) per annum. If, for
                                    example and as a means of illustration only,
                                    the actual amount of the Electrical Service
                                    Upgrade Cost is Fifty-Nine Thousand Nine
                                    Hundred Thirty-One Dollars (US$59,931.00),
                                    then after Landlord's contribution to the
                                    Electrical Service Upgrade Cost of Thirty-
                                    Nine Thousand Nine Hundred Sixty-Five and
                                    50/100 Dollars (US$39,965.50) (the first

                          TENANT IMPROVEMENT ALLOWANCE

The Landlord hereby agrees to contribute to Tenant for the Tenant's Work, but
not as part of the Landlord's Work, a "Tenant Improvement Allowance" in an
amount up to, but in no event to exceed, Ten Dollars (US$10.00) per square foot
multiplied by the total rentable square feet of the Leased Premises, as
calculated by Landlord pursuant to Paragraph 1 of this Lease (approximately One
Hundred Sixty-Seven Thousand Five Hundred Dollars (US$167,500.00) [16,750
rentable square feet multiplied by US$10.00 per square foot]), which Tenant
Improvement Allowance shall be contributed by Landlord following Landlord's
receipt of evidence reasonably satisfactory to Landlord that all contractors,
workmen, material and service suppliers and all the persons having claims
against the Tenant for payment of work done or materials or services supplied in
connection with the Tenant's Work have been paid in full.  Landlord's
contribution of the Tenant Improvement Allowance is for the purpose set forth in
Paragraph 5(f) of Schedule "F" attached hereto.  It is a condition precedent to
                  ------------                                                 
Landlord's obligation to contribute the Tenant Improvement Allowance hereunder
that a claim for said contribution of the Tenant Improvement Allowance be made
by Tenant, along with the delivery by Tenant of reasonably satisfactory evidence
of all of the foregoing, to Landlord.  Landlord may, but shall not be obligated
to, pay any contractor, workmen, material and/or service suppliers and all the
persons who performed work or supplied materials or services in connection with
the Tenant's Work, if the Tenant has failed to do so, and the Tenant shall pay
the Landlord on demand the amount the Landlord has so paid, unless such payment
is made by Landlord prior to the Landlord's contribution to the Tenant of any of
the Tenant Improvement Allowance, in which case the amount of such payment by
Landlord shall be deducted from all or any remaining portion of the Tenant
Improvement Allowance.

                                  SCHEDULE "H"

                                OPTION TO RENEW

     (a)  The Landlord covenants with the Tenant that if the Tenant duly and
     regularly pay s the Rent and any and all other amounts required to be paid
     pursuant to this Lease and performs each and every covenant, proviso and
     agreement on the part of the Tenant to be paid, rendered, observed and
     performed herein, the Landlord hereby, upon written notice by the Tenant
     and received by the Landlord not more than nine (9) months nor less than
     six (6) months prior to the expiration of the ten-expiring Term of the
     first Renewal Term, as applicable, grants to the Tenant two (2) consecutive
     options to renew (an "Option" or, collectively, the "Options") this Lease
     for an additional five (5) year period each (a "Renewal Term" or,
     collectively, the "Renewal Terms"), on the same terms and conditions as in
     this Lease at the commencement of the applicable Renewal Term, save and
     except for Tenant's right to any further renewal (except for the Renewal
     Terms), Landlord's Work, Basic Rent, and any Tenant Improvement Allowance.

     (b)  The Basic Rent for each applicable Renewal Term shall be determined by
     negotiations between the parties hereto, and it is agreed that during such
     negotiations in respect of Basic Rent, they will be guided by the "Fair
     Market Rental Rate" (as hereinafter defined) for the Leased Premises and by
     the provisions of Paragraphs (c) and (d) below; provided, however, in no
     event shall the Basic Rent per annum applicable to the Renewal Terms be
     lower that the Basic Rent per annum for the last year of the Term just
     ending.

     (c)  For the purposes of this Schedule "H" and Schedule "L" attached hereto
                                   ------------     ------------                
     only, the term "Fair Market Rental Rate" shall mean the annual amount per
     rentable square foot that a willing, comparable non-renewal, non-equity,
     non-expansion tenant would pay for unencumbered space, and Landlord would
     accept, at arm's length, giving appropriate consideration to annual rental
     rates per rentable square foot, escalations (including type, gross or net,
     and if gross, whether base year or expense stop), abatement provisions
     reflecting free rent, if any, brokerage commissions, if any, length of the
     lease term, and size and location of the premises being leased.  To allow
     for a decision as to the Fair Market Rental Rate, the parties hereto may
     consider, for comparison purposes, transactions in comparable,
     unencumbered, non-renewal space in "Comparable Buildings," which shall mean
     Comparable Buildings to the Building in use, quality and size, and located
     in the major business district of the City of Irvine, State of California.
     Landlord shall give written notice of Landlord's determination of the Fair
     Market Rental Rate to Tenant promptly after Landlord's receipt of Tenant's
     written notice to exercise an Option hereunder, and the parties hereto will
     then proceed to determine the Basic Rent for the applicable Renewal Term in
     accordance with this Schedule "H".
                          ------------ 

     (d)  In the event Tenant rejects the determination of the Fair Market
     Rental Rate submitted by Landlord, then Landlord and Tenant shall attempt
     in good-faith to agree upon such Fair Market Rental Rate. If Landlord and
     Tenant fail to reach agreement within fifteen (15) days following Tenant's
     receipt of Landlord's determination of the Fair Market Rental Rate (the
     "Outside Agreement Date"), then each party's determination of the Fair
     Market Rental Rate shall be submitted to appraisal in accordance with the
     following:

        (i)     Landlord and Tenant shall each appoint one independent appraiser
     who shall by profession be a real estate broker active over the previous
     five (5) year period ending on the date of such appointment in the leasing
     of commercial properties in the City of Irvine, California. Each such
     appraiser shall be appointed within fifteen (15) days after the Outside
     Agreement Date If either Landlord or Tenant fails to timely appoint an
     appraiser, as the other party's request, JAMS/Endispute or an "Arbitrator"
     (as defined in clause (d)(v) below) shall appoint their or its appraiser.

        (ii)    The two (2) appraisers so appointed shall, within fifteen (15)
     days after the appointment of the last appraiser, agree upon and appoint a
     third appraiser who shall be qualified under the same criteria.

        (iii)  The three (3) appraisers shall, within thirty (30) days after the
     appointment of the third appraiser, decide whether the parties shall use
     Landlord's or Tenant's submitted Fair-Market Rental Rate, and shall notify
     Landlord and Tenant in writing thereof. The appraisers' determination shall
     be limited solely to the issue of whether Landlord's or Tenant's submitted
     Fair Market Rental Rate for the applicable Renewal Term is closest to the
     then-prevailing Fair Market Rental Rate, as determined by the appraisers
     taking into account the requirements set forth in this Schedule "H". Such
                                                            ------------
     decision shall be based upon the projected, then-prevailing Fair Market
     Rental Rate as of the proposed commencement date of the applicable Renewal
     Term.

        (iv)    The three (3) appraisers' majority decision shall be binding
     upon Landlord and Tenant, without any right of appeal or objection,
     judicial or otherwise.

        (v)     If the appraisers fail to agree upon and appoint a third
     appraiser, both appraisers shall be dismissed and the matter shall be
     submitted to arbitration under the provisions of JAMS/Endispute in Orange
     County, California, with a determination within thirty (30) days thereafter
     based upon the same procedures set forth above (i.e., by selecting either
                                                     ---- 
     Landlord's or Tenant's submitted Fair Market Rental Rate only, as closest
                                                              ----
     to the then-prevailing Fair Market Rental Rate). If JAMS/Endispute no
     longer exists, then the matter shall be settled by binding arbitration
     before a single arbitrator appointed pursuant to the Rules of the American
     Arbitration Association in effect at the time of the arbitration (the
     "Rules") and shall otherwise be conducted pursuant to such Rules. The
     "Arbitrator" 

                                      H-1
<PAGE>
 
     shall be a lawyer or judge having at least twenty (20) years professional
     experience, and the arbitration shall be held in Orange County, California,
     and be conducted in confident and without public disclosure by the
     Arbitrator or any party or their representatives of any matters relevant to
     the arbitration. Judgment may be entered on any arbitration award in any
     court having competent jurisdiction thereof.

        (vi)    All costs of appraisal hereunder, and arbitration if necessary,
     shall be shared equally by the parties hereto.

     (e)  The Tenant agrees to execute the Landlord's commercially reasonable
     lease amendment agreement then, at the commencement of each applicable
     Renewal Term, being used by the Landlord for the Building to give effect to
     an Option, if exercised by the Tenant. The Tenant shall execute such
     commercially reasonable agreement prior to the commencement date of the
     applicable Renewal Term.

     (f)  Notwithstanding the above, if the Tenant does not exercise Tenant's
     first Option in accordance with this Schedule "H," then the Options are
                                          -----------
     hereby automatically terminated and of not further force and effect.

                      OCCUPANCY PRIOR TO COMMENCEMENT DATE

The Tenant may enter the Property, including the Leased Premises, upon full
execution and delivery of this Lease between Landlord and Tenant, for the sole
purpose of the Tenant's Work (the "Improvement Period").  Tenant's use of the
Property, including the Leased Premises, during the Improvement Period shall be
upon and subject to the following conditions:

1.   During the Improvement Period, the Tenant, its servants, agents, employees,
     contractors, subcontractors, officers and directors, shall be subject to
     and bound by all of the terms and conditions of this Lease, including,
     without limiting the generality of the foregoing, all insurance and
     indemnification obligations of Tenant, subject only to the following:

     (a)  During the Improvement Period, the Tenant shall not be obligated to
          pay Basic Rent (except as otherwise provided herein); and

     (b)  In the event the Tenant commences to conduct Tenant's business from
          the Leased Premises during the Improvement Period, all Basic Rent
          shall commence form the date of such commencement, notwithstanding
          that the Term has not yet begun.

     (c)  [Intentionally Deleted].

2.   Should Tenant enter upon the Property, including the Leased Premises, under
     the terms of this Schedule "I" during the Improvement Period, it is hereby
                       -----------
     agreed that Tenant, and Tenant's servants, agents, employees, contractors,
     subcontractors, officers and directors or any other persons under Tenant's
     control (collectively, "Tenant's Representatives"), shall be subject to the
     direction of Landlord and Landlord's general contractor.  If in the sole
     and absolute discretion of Landlord, the presence of Tenant's
     Representatives and their work interferes with the construction and
     completion of the Landlord's Work or shall detrimentally affect Landlord's

     (a)  Provided that the Tenant duly and regularly pays the Rent and any and
     all other amounts required to be paid pursuant to this Lease and performs
     each and every covenant, proviso and agreement on the part of the Tenant to
     be paid, rendered, observed and performed herein, the Landlord hereby
     grants to the Tenant the right of first opportunity to lease (herein called
     the "Right of First Opportunity Lease") all of the then-available,
     additional space located on the second (2nd) floor of the Building, as

     (b)  The Right of First Opportunity of Lease shall be subject to the
     Opportunity Space becoming vacant and available for lease. The Opportunity
     Space shall be deemed "available for lease" only to the extent that such
     space is not subject to a lease of another tenant(s) (i.e., right of
                                                           ---
     expansion, first offer, renewal or any other rights of a third party).

     (c)  The Landlord will notify the Tenant in writing (herein called the
     "Notification") of the date on which the Opportunity Space will become
     vacant and available for lease by the Tenant, subject to any existing

     intention to lease the Opportunity Space by giving notice in writing to the
     Landlord within thirty (30) days after such Notification, failing which the
     Right of First Opportunity to Lease shall automatically terminate and be of
     no further force and effect, and Landlord will have the right to lease the
     Opportunity Space to any third party.

     (d)  The Notification will be sent to the Tenant no later than seven (7)
     months prior to the Opportunity Space Commencement Date.

     (e)  The expiration date of the term of the lease for the Opportunity Space
     shall coincide with the Expiration Date of this Lease or the applicable
     Renewal Term, if exercised.

     (f)  The Basic Rent per square foot for the Opportunity Space shall be at
     the Fair Market Rental Rate, as reasonably determined by Landlord and
     Tenant solely in accordance with Paragraph (c) of Schedule "H" attached

     hereto (without the use of the appraisal/arbitration procedures set forth
     in Paragraph (d) of such Schedule "H").
                              -----------
        
     (g)  Landlord shall give written notice of Landlord's determination of the
     Fair Market Rental Rate to Tenant concurrently with Landlord's delivery of
     the Notification to Tenant. Thereafter, the Basic Rent per square foot for

     Tenant in writing within sixty (60) days after the Notification, failing
     which the Right of First Opportunity to Lease as to the specific
     Opportunity Space may, at Landlord's option, automatically terminate and be
     of no further force and effect, and the Landlord will have the right to
     lease the Opportunity Space to any third party.

     (h)  The Opportunity Space shall be subject to the same terms and
     conditions as in this Lease, except that there will be no Landlord's Work,
     no Tenant Improvement Allowance, and the Tenant's Proportionate Share will
     be increased accordingly.

     (i)  Subject to Tenant's prior inspection, the Tenant agrees to accept the
     Opportunity Space in its then-current "AS/IS-WHERE/IS" condition "WITH ALL
     FAULTS" as of the Opportunity Space Commencement Date.

     (j)  The Tenant agrees to execute the Landlord's commercially reasonable
     lease amendment agreement then, at the Opportunity Space Commencement Date,
     being used by the Landlord for the Building to give effect to the Right of
     First Opportunity to Lease, if exercised by the Tenant.

     (k)  Notwithstanding the above, if the Tenant does not exercise the Right
     of First Opportunity to Lease in accordance with this Schedule "L", then
                                                           ------------
     the Right of First Opportunity to Lease shall automatically terminate and
     be of no further force and effect, and Landlord will have the right to
     lease the Opportunity Space to any third party.

     3.1   LEASE OF PREMISES.  In consideration of the agreements contained

interruption of the business of Tenant or Tenant's use or occupancy of the
Premises. Notwithstanding anything to the contrary set forth in the preceding
provisions of this Section 3.2, no exercise by Landlord of any of the rights

     5.2  PAYMENT OF BASE RENT.  Base Rent for each Lease Year shall be payable
           -------------------
in equal monthly installments, in advance, without demand, notice, deduction,
offset or counterclaim, on or before the first (1st) day of each and every
calendar month during the Term; provided, however, that the installment of the
Base Rent payable for the first (1st) full calendar month of the Term (and, if
the Commencement Date occurs on a date other than on the first (1st) day of a
calendar month, Base Rent prorated from such date until the first (1st) day of
the following month) shall be due and payable on the full execution and delivery
of this Lease. Tenant shall pay Base Rent and all Additional Rent, by good
check, made payable to Landlord, or in lawful currency of the United States of
America, to Landlord at P.O. Box 631047, Baltimore, Maryland 21263-1047 or to
such other address or in such other manner as Landlord from time to time
specifies by written notice to Tenant. Any payment made by Tenant to Landlord on
account of Base Rent may be credited by Landlord to the payment of any late
charges then due and payable and to any Base Rent or Additional Rent then past
due before being credited to Base Rent currently due.

     5.3  ADDITIONAL RENT.  All sums payable by Tenant under this Lease, other
          ---------------
than Base Rent, shall be deemed "Additional Rent," and, unless otherwise set

or Additional Rent to a "lockbox" or other depository whereby checks issued in
payment of Base Rent or Additional Rent (or both, as the case may be) are
initially cashed or deposited by a person or entity other than Landlord (albeit
on Landlord's authority), then, for any and all purposes under this Lease: (i)
Landlord shall not be deemed to have accepted such payment until ten (10) days
after the date on which Landlord shall have actually received such funds; and
(ii) Landlord shall be deemed to have accepted such payment if (and only if)
within said ten (10) day period, Landlord shall not have refunded (or attempted
to refund) such payment to Tenant. Nothing contained in the immediately
preceding sentence shall be construed to place Tenant in default of Tenant's
obligation to pay Rent if and for so long as Tenant shall timely pay the Rent
required pursuant to this Lease in the manner designated by Landlord.

                                   ARTICLE 6
                               SECURITY DEPOSIT
                                        
     6.1  GENERAL.  Simultaneously with the execution of this Lease, Tenant
          -------
shall deposit in the form of cash or an irrevocable letter of credit the
Security Deposit with Landlord, which shall be held by Landlord, without
obligation for interest, as security, for the performance of Tenant's
obligations and covenants under this Lease. It is expressly understood and
agreed that such deposit is not an advance rental deposit or a measure of
Landlord's damages in case of an Event of Default. The terms and conditions of
this Article 6 shall survive the Expiration Date and any sooner termination of
the Term in accordance with the terms and conditions of this Lease.

     6.2  SECURITY IN THE FORM OF CASH.  If an Event of Default shall occur or
          ---------------------------- 
if Tenant fails to surrender the Premises in the condition required by this
Lease, Landlord shall have the right (but not the obligation), and without
prejudice to any other remedy which Landlord may have on account thereof, to
apply all or any portion of the Security Deposit to cure such default or to
remedy the condition of the Premises. If Landlord so applies the Security
Deposit or any portion thereof before the Expiration Date or earlier termination
of this Lease, Tenant shall deposit with Landlord, upon demand, the amount
necessary to restore the Security Deposit to its original amount. If Landlord
shall sell or transfer its interest in the Building, Landlord shall have the
right to transfer the Security Deposit to such purchaser or transferee, in which
event Tenant shall look solely to the new landlord for the return of the
Security Deposit, and
<PAGE>
 
Landlord, after having given notice of such transfer to Tenant, shall thereupon
shall be released from all liability to Tenant for the return of the Security
Deposit to the extent of all or any portion thereof so transferred. Although the
Security Deposit shall be deemed the property of Landlord, any remaining balance
of the Security Deposit shall be returned to Tenant at such time after the
Expiration Date or earlier termination of this Lease that all of Tenant's
obligations under this Lease have been fulfilled.

     6.3  SECURITY IN THE FORM OF AN IRREVOCABLE LETTER OF CREDIT.  The
           ------------------------------------------------------
irrevocable letter of credit shall be in both form and substance acceptable to
Landlord and must be maintained throughout the Term and for a period of sixty
(60) days thereafter by Tenant. Any letter of credit delivered to Landlord by
Tenant in fulfillment of its obligations to Landlord pursuant to this Article 6
shall have a term of not less than one (1) year. In the event that any letter of
credit delivered by Tenant to Landlord pursuant to its obligations under this
Lease shall have a term which expires prior to that date which is sixty (60)
days after the Expiration Date, then and in such event, not later than thirty
(30) days prior to the expiration date of the term of such letter of credit,
Tenant shall deliver to Landlord a successor letter of credit meeting the
requirements of this Lease. The failure of Tenant to deliver a successor letter
of credit to Landlord meeting the requirements of this Lease not later than
thirty (30) days prior to the expiration date of such letter of credit, as
aforesaid, shall constitute an Event of Default. In the event of default by
Tenant hereunder, Landlord shall have the right to redeem all or any portion of
such letter of credit to cure such default by notifying in writing both Tenant
and the credit institution issuing the letter of credit of such default
following expiration of the period to cure such default as provided in Article
22 of this Lease. In the event any portion of such letter of credit has been
redeemed by Landlord, Tenant shall be required to restore such letter of credit
to its full amount as provided herein. Not later than sixty (60) days after the
expiration of the Term, Landlord shall return such letter of credit to Tenant,
after the Post Move-Out Inspection and upon final receipt of any sums owed to
Landlord pursuant to the provisions of the terms of this Lease. If Landlord
shall sell or transfer its interest in the Building, Tenant shall, at Landlord's
request, amend said letter of credit so that it is payable to such purchaser or
transferee, in which event Tenant shall look solely to such purchaser or
transferee for the return of the letter of credit, and Landlord thereupon shall
be released from all liability to Tenant for the return of the Security Deposit.
In the event that said letter of credit shall be amended by Tenant, at
Landlord's request, so that it is payable to such purchaser or transferee, any
reasonable fee paid by Tenant to the financial institution issuing said letter
of credit in connection with such amendment of the letter of credit shall be
reimbursed to Tenant by Landlord within thirty (30) days after written request
shall be made therefor by Tenant to Landlord (which request shall be accompanied
by evidence of Tenant's payment of such fee).

     6.4  POST MOVE-OUT INSPECTION.  Landlord and Tenant shall conduct a "Post
          ------------------------ 
Move-Out Inspection" of the Premises within fifteen (15) days after the
Expiration Date or earlier termination of this Lease, but in any event prior to
reentry by Landlord for the purpose of preparing the Premises for re-letting.
Failure on Tenant's part to attend the Post Move-Out Inspection, after not less
than five (5) days' prior notice from Landlord of the exact date(s) thereof,
within said fifteen (15) day period shall be deemed an acceptance by Tenant of
Landlord's assessment of the condition of the Premises.

              PARK COMMON AREA MAINTENANCE EXPENSES ("PCAM") AND
                      BUILDING OPERATING EXPENSES ("BOE")
                                        
     7.1  TENANT'S PROPORTIONATE SHARES OF PCAM AND BOE.  Tenant shall pay to
          ---------------------------------------------
Landlord throughout the Term, as Additional Rent, (a) Tenant's Proportionate
Share of PCAM, and (b) Tenant's Proportionate Share of BOE. In the event that
the Commencement Date or the Expiration Date are other than the first (1st) day
of a Calendar Year, then Tenant's Proportionate Shares of PCAM and BOE shall be
adjusted to reflect the actual period of occupancy during the Calendar Year.

     7.2  PCAM DEFINED.  As used herein, the term "PCAM" shall mean all expenses
          ------------
and costs of every kind 
<PAGE>
 
and nature which Landlord incurs because of or in connection with the
maintenance and operation of the Park. In any event, PCAM shall include, without
limitation, all costs, expenses and disbursements incurred or made in connection
with the following:

          (a)  Wages and salaries of all employees, including without limitation
an on-site management agent and staff, whether employed by Landlord or the
Landlord's management company, engaged in the operation and maintenance or
security of the Park and all costs related to or associated with such employees

footage to the Building or for the sole benefit of a Building tenant pursuant to
its lease), the cost of which shall be amortized over the useful life of the
same, as determined in accordance with generally accepted accounting principles,
consistently applied, together with interest on the unamortized balance of such
cost at the Interest Rate or such higher rate as may have been paid by Landlord
on funds borrowed for the purposes of constructing said capital improvements but
only to the extent that such capital improvement actually results in the
reduction of PCAM;

          (g)  All maintenance of the Park, including, without limitation, trash
removal, painting, ice and snow removal, landscaping, groundskeeping and the
patching, painting and resurfacing of roads, driveways and parking lots;

     7.4  EXCLUSIONS FROM PCAM AND BOE.  PCAM and BOE shall not include the
          ----------------------------
following:

          (a)  Legal fees, space planners' fees, real estate brokers' leasing

future leasing of space in the Park;

          (b)  Legal fees incurred in connection with any disputes with other

          (f)  Costs and expenses associated with the operation of the business

the extent the actions of Tenant or any other tenant may be in issue), costs of
selling or financing any of Landlord's interest in the Building and/or the Park;
and

          (g)  Costs and expenses directly resulting from the gross negligence
or willful misconduct of Landlord or its Agents.

In addition, in the calculation of any costs or expenses under this Article 7,
it is expressly understood that no cost or expense shall be charged more than
once.

     7.5  ESTIMATED PAYMENTS.  Landlord shall submit to Tenant, before the
          ------------------
beginning of each Calendar Year, a statement of Landlord's estimates of the PCAM
and BOE payable by Tenant during such Calendar Year. In addition to the Base
Rent, Tenant shall pay to Landlord on or before the first day of each month
during such Calendar Year an amount equal to one-twelfth (1/12) the estimated
PCAM and BOE payable by Tenant for such Calendar Year as set forth in Landlord's
statement. If Landlord fails to give Tenant notice of its estimated payments due
under this Section for any Calendar Year, then Tenant shall continue making
monthly estimated payments in accordance with the estimate for the previous
Calendar Year until a new estimate is provided. If Landlord determines that,
because of unexpected increases in PCAM or BOE or other reasons, Landlord's
estimate of the PCAM and/or BOE was too low, then Landlord shall have the right
to give a new statement of the estimated PCAM and BOE due from Tenant for such
Calendar Year or the balance thereof and to bill Tenant for any deficiency which
may have accrued during such Calendar Year, and Tenant shall thereafter pay
monthly estimated payments based on such new statement; provided, however, that
Landlord shall not exercise its right to give a new statement of estimated PCAM
and/or BOE for any Calendar Year or the balance thereof on more than two (2)
occasions during or with respect to any Calendar Year.

     7.6  ACTUAL PCAM AND BOE.  Within one hundred twenty (120) days after the
          -------------------
end of each Calendar Year, Landlord shall submit a statement to Tenant showing
the actual PCAM and BOE for such Calendar Year and Tenant's Proportionate Shares
of the amount of such PCAM and BOE. If for any Calendar Year, Tenant's estimated
monthly payments exceed Tenant's Proportionate Share of the actual PCAM and BOE
for such Calendar Year, then Landlord shall give Tenant a credit in the amount
of the overpayment toward Tenant's next monthly payments of
<PAGE>
 
estimated PCAM and BOE. If for any Calendar Year Tenant's estimated monthly
payments are less than Tenant's Proportionate Share of the actual PCAM and BOE
for such Calendar Year, then Tenant shall pay the total amount of such
deficiency to Landlord within thirty (30) days after receipt of the statement
from Landlord. Landlord's and Tenant's obligations with respect to any
overpayment or underpayment of PCAM and BOE shall survive the expiration or
termination of this Lease.

     7.7  TENANT'S RIGHT TO AUDIT.  In the event Tenant shall dispute the amount
           ----------------------
set forth in Landlord's statement of actual PCAM and BOE, Tenant shall have the
right, not later than sixty (60) days following receipt of such statement, to
cause Landlord's books and records with respect to the preceding Calendar Year
to be audited by an independent Certified Public Accountant mutually acceptable
to Landlord and Tenant. Such audit shall occur upon not less than five (5) days
prior written notice to Landlord, at Landlord's place of business or the actual
location of Landlord's books and records if different from Landlord's place of
business, during Landlord's normal business hours. The amounts payable under
this Article by Landlord to Tenant or by Tenant to Landlord, as the case may be,
shall be appropriately adjusted on the basis of such audit. If such audit
discloses a liability for further refund by Landlord to Tenant in excess of
three percent (3%) of the payments previously made by Tenant for such Calendar
Year, the cost of such audit shall be borne by Landlord and shall not be
considered as a PCAM or BOE for purposes of this Lease; otherwise, the cost of
such audit shall be borne by Tenant. Notwithstanding the foregoing, in no event
shall Landlord's cost for such audit exceed One Thousand Five Hundred Dollars
($1,500.00). If Tenant shall not request an audit in accordance with the
provisions of this Section within sixty (60) days of receipt of Landlord's
statement of actual PCAM and BOE, such statement shall be conclusively binding
upon Landlord and Tenant.

                                   ARTICLE 8
                                     TAXES
                                        
     Tenant shall pay to Landlord throughout the Term, as Additional Rent,
Tenant's Proportionate Share of Real Estate Taxes. In the event that the
Commencement Date or the Expiration Date are other than the first day of a
Calendar Year, the Tenant's Proportionate Share of Real Estate Taxes shall be
adjusted to reflect the actual period of occupancy during the Calendar Year.
"Real Estate Taxes" shall mean all taxes and assessments, including but not
limited to, general or special, ordinary or extraordinary, foreseen or
unforeseen, assessed, levied or imposed by any governmental authority upon the
Building and the Building Tax Parcel and upon the fixtures, machinery, equipment
or systems in, upon or used in connection with any of the foregoing, and the
rental, revenue or receipts derived therefrom, under the current or any future
taxation or assessment system or modification of, supplement to, or substitute
for such system. Real Estate Taxes also shall include special assessments which
are in the nature of or in substitution for real estate taxes, including,
without limitation, road improvement assessments, special use area assessments
and school district assessments. If at any time the method of taxation
prevailing at the Date of Lease shall be altered so that in lieu of, as a
substitute for or in addition to the whole or any part of the taxes now levied
or assessed, there shall be levied or assessed a tax of whatever nature, then
the same shall be included as Real Estate Taxes hereunder. Further, for the
purposes of this Article, Real Estate Taxes shall include the reasonable
expenses (including, without limitation, attorneys' fees) incurred by Landlord
in challenging or obtaining or attempting to obtain a reduction of such Real
Estate Taxes, regardless of the outcome of such challenge. Notwithstanding the
foregoing, Landlord shall have no obligation to challenge Real Estate Taxes. If,
as a result of any such challenge, a tax refund is made to Landlord, then the
amount of such refund less the expenses of the challenge shall be deducted from
Real Estate Taxes due in the Lease Year such refund is received. Landlord shall
charge Tenant for its Proportionate Share of Real Estate Taxes in accordance
with the procedures established under Sections 7.5 and 7.6 for payment of PCAM
and BOE.


                                   ARTICLE 9

     9.1  PARKING SPACES.  During the Term, Tenant shall have the right to use
          --------------
the Parking Space Allocation, 
<PAGE>
 
which shall be unreserved and non-exclusive parking spaces available in the
Parking Facilities.

     9.2  CHANGES TO PARKING FACILITIES.  Landlord shall have the right, from
          -----------------------------
time to time, without Tenant's consent, to change, alter, add to, temporarily
close or otherwise affect the Parking Facilities in such manner as Landlord, in
its sole discretion, deems appropriate, including, without limitation, the right
to designate reserved spaces available only for use by one or more tenants
(however, in such event, those parking spaces shall still be deemed Park Common
Area for the purpose of the definitions of PCAM and BOE), provided that, except
in emergency situations or situations beyond Landlord's control, Landlord shall
provide alternative Parking Facilities. Notwithstanding anything to the contrary
set forth in the preceding provisions of this Section 9.2, Landlord shall not
exercise any of the rights reserved to Landlord pursuant to this Section 9.2 to
change, alter or otherwise permanently affect the Parking Facilities in such a
fashion as to materially adversely affect Tenant's right to use the Premises for
the Permitted Use.

                                  ARTICLE 10
                                      USE
                                        
     Tenant shall occupy the Premises solely for the Permitted Use. The Premises
shall not be used for any other purpose without the prior written consent of
Landlord. Tenant shall comply, at Tenant's expense, with (i) all present and
future laws, ordinances, regulations and orders of the United States of America,
the Commonwealth of Virginia and any other public or quasi-public federal, state
or local authority having jurisdiction over the Premises, and (ii) any
reasonable requests of Mortgagee or any insurance company providing coverage
with respect to the Premises. Tenant shall not use or occupy the Premises in any
manner that is unlawful or dangerous or that shall constitute waste,
unreasonable annoyance or a nuisance to Landlord or the other tenants of the
Park. Tenant shall not use, store or dispose of any hazardous, dangerous,
inflammable, toxic or explosive materials on the Premises.

                                  ARTICLE 11
                           ASSIGNMENT AND SUBLETTING
                                        
     11.1  CONSENT.  Tenant shall not assign, transfer, mortgage or otherwise
           -------
encumber this Lease or sublet or rent (or permit a third party to occupy or use)
the Premises, or any part thereof, nor shall any assignment or transfer of this
Lease or the right of occupancy hereunder be effected by operation of law or
otherwise, without the prior written consent of Landlord which shall not be
unreasonably withheld or delayed. For purposes of the foregoing prohibitions, a
transfer at any one time or from time to time of forty-nine percent (49%) or
more of an interest in Tenant (whether stock, partnership interest or other form
of ownership or control) by any person(s) or entity(ties) having an interest in
ownership or control of Tenant at the Date of Lease shall be deemed to be an
assignment of this Lease. If Landlord consents to the proposed assignment or
subletting, the initial Tenant shall remain liable under this Lease and the
initial Tenant shall pay to Landlord one-half (1/2) of the "net" amount (such
"net" amount being the gross amount thereof less any reasonable expenses
incurred by Tenant for legal fees, brokerage commissions or subleasehold
improvements) of any amount of rent or other sums directly or indirectly
received by Tenant from any subtenant or assignee which exceeds the Rent. Any
assignment, encumbrance, or sublease without Landlord's written consent shall be
voidable by Landlord and, at Landlord's election, constitute an Event of Default
hereunder. Neither the consent by Landlord to any assignment, transfer,
encumbrance or subletting, nor the assignment or subletting to any subsidiary or
affiliate of Tenant made without the necessity of consent from Landlord in
accordance with Section 11.3 of this Lease, nor the collection or acceptance by
Landlord of rent from any assignee, subtenant or occupant shall be construed as
a waiver or release of the initial Tenant from the terms and conditions of this
Lease or relieve Tenant or any subtenant, assignee or other party from obtaining
the consent in writing of Landlord to any further assignment, transfer,
encumbrance or subletting. Tenant hereby assigns to Landlord the rent and other
sums due from any subtenant, assignee or other occupant of the Premises and
hereby authorizes and directs each such subtenant, assignee or other occupant to
pay such rent or other sums directly to Landlord; provided, however, that until
the occurrence of an Event of Default, Tenant shall have the license to continue
collecting such rent and other sums.
<PAGE>
 
     11.2  SURRENDER.  Except as set forth in the last sentence of this Section
           ---------
11.2, in the event of any assignment or subletting (including any assignment or
subletting approved by Landlord or not requiring the prior written consent of
Landlord), Landlord shall have the right, by notice to Tenant, to terminate this
Lease at any time during the Term on or after the effective date of such
assignment or subletting, in the event of an assignment as to all of the
Premises and, in the event of a sublease, as to the subleased portion of the
Premises, and to require that all or part, as the case may be, of the Premises
be surrendered to Landlord for the balance of the Term. Landlord hereby agrees
that it shall not exercise any of the rights granted to Landlord pursuant to
this Section 11.2 in connection with any sublease or subleases approved by
Landlord and entered into by Tenant, as sublandlord, and parties unrelated to
Tenant, as subtenants, prior to that date which is the third (3rd) anniversary
of the Commencement Date so long as the aggregate area subleased pursuant to all
such subleases shall not exceed one-half (1/2) of the rentable square footage of
the Premises as of the Date of Lease.

     11.3  ASSIGNMENT OR SUBLETTING TO SUBSIDIARY OR AFFILIATE OF TENANT. 
           -------------------------------------------------------------
Notwithstanding anything to the contrary set forth in this Article 11, Tenant
shall have the right to assign this Lease or to sublet the Premises, in whole or
in part, without the prior written consent of Landlord, so long as any such
assignment or subletting is made with or to any wholly-owned subsidiary or
affiliate of Tenant. For purposes hereof, "affiliate" means any corporation,
partnership, association, or other legal entity which, directly or indirectly,
controls or is controlled by or is under common control with Tenant. For
purposes of the definition "affiliate," the word "control" (including, without
limitation, "controlled by" and "under common control with") as used with
respect to any such legal entity, shall mean the possession, directly or
indirectly, of the power to direct or cause the direction of the management and
policy of such legal entity, whether through the ownership of voting securities,
by contract or otherwise. Tenant shall give prompt notice to Landlord of any
assignment of this Lease or subletting of the Premises made with or to any
wholly-owned subsidiary or affiliate of Tenant in accordance with the terms and
conditions of this Section 11.3.

                                  ARTICLE 12
                            MAINTENANCE AND REPAIR
                                        
     12.1  LANDLORD'S OBLIGATION.  As long as no Event of Default has occurred
           ---------------------
and is continuing, Landlord shall, at its expense, maintain only the roof,
foundation and the structural soundness of the exterior walls of the Building in
good repair, reasonable wear and tear excepted. Tenant shall repair and pay for
any damage caused by the negligence of Tenant or Tenant's employees, agents or
invitees, or caused by Tenant's default hereunder. The term "walls" as used in
this Section shall not include windows, glass, doors, special store fronts or
office entries. Tenant shall immediately give Landlord written notice of any
defect or need for repairs. Subject to Force Majeure, Landlord shall commence
the cure of any such defect or such repair within five (5) days after Landlord's
receipt of such notice from Tenant thereof and shall thereafter diligently
prosecute the cure of such defect or such repair so as to complete such cure or
repair within a reasonable period of time. Landlord's liability with respect to
any defects, repairs or maintenance for which Landlord is responsible under any
of the provisions of this Lease shall be limited to the cost of such repairs or
maintenance or the curing of such defect.

     12.2  TENANT'S OBLIGATION.  Tenant shall, at its own expense, maintain all
           -------------------
parts of the Premises (except those for which Landlord is either expressly
responsible or elects to undertake pursuant to Section 12.1 or 12.3 of this
Lease) in good condition, promptly making all necessary repairs and
replacements, including, but not limited to, windows, glass and plate glass,
doors, any special office entry, interior walls and finish work, floors and
floor covering, downspouts, gutters, lighting and electrical systems, dock
boards, truck doors, dock bumpers, paving, HVAC systems (including fixtures and
equipment), plumbing work and fixtures, termite and pest extermination, regular
removal of trash and debris. Tenant shall not be obligated to repair any damage
caused by fire, tornado or other casualty not caused by Tenant's fault or
negligence, when repair of such damage is undertaken by Landlord pursuant to
Section 21.1 below, except that Tenant shall be obligated to repair all wind
damage to windows, glass and plate glass doors, and all other
<PAGE>
 
glass in the Premises. Tenant shall, at its own expense, keep the sidewalks in
front of the Premises free from obstructions of any and all nature, keep the
Premises in a clean and sanitary condition, maintain suitable receptacles for
trash and refuse, and promptly remove from the Premises all accumulations of
trash and refuse. In order to fulfill the immediately foregoing obligations,
Tenant shall, at its expense, enter into a contract for janitorial and/or char
service with a contractor reasonably acceptable to Landlord. Unless otherwise
provided for by Landlord, Tenant shall, at its expense, enter into a regularly
scheduled preventive maintenance/service contract for all hot water, heating and
air conditioning systems and equipment within the Premises. The maintenance
contractor, the contract and the maintenance schedule must be given prior
approval in writing by Landlord. The service contract must include all services
suggested by the equipment manufacturer in the operation/maintenance manual and
must become effective (and a copy thereof delivered to Landlord) within thirty
(30) days of the date Tenant takes possession of the Premises. Except as and
upon the conditions set forth elsewhere in this Lease, without the prior written
consent of Landlord, Tenant shall not have access to the roof of the Building
for any purpose whatsoever.

     12.3  LANDLORD'S RIGHT TO MAINTAIN OR REPAIR.  If, within five (5) days
           --------------------------------------
following notice to Tenant, Tenant fails to commence to repair or replace any
damage to the Premises or Building which is Tenant's obligation to perform, and
diligently pursue timely completion of such repair and replacement, Landlord
may, at its option, cause all required maintenance, repairs or replacements to
be made. Tenant shall promptly pay Landlord all costs incurred in connection
therewith plus interest thereon at the Interest Rate from the due date until
paid.

                                  ARTICLE 13
                       INITIAL CONSTRUCTION; ALTERATIONS

     13.1  INITIAL CONSTRUCTION.  Landlord and Tenant agree that the
           --------------------
construction of the Tenant Work and other initial construction with respect to
the Premises shall be performed in accordance with the Work Agreement.

     13.2  ALTERATIONS.  Tenant shall not make or permit any Alterations without
           -----------
the prior written consent of Landlord. Landlord may impose any reasonable
conditions to its consent, including, without limitation: (i) delivery to
Landlord of written and unconditional waivers of mechanic's and materialmen's
liens as to the Premises, the Building and the Land for all work, labor and
services to be performed and materials to be furnished, signed by all
contractors, subcontractors, materialmen and laborers participating in the
Alterations; (ii) prior approval of the plans and specifications and Tenant's
contractor(s) with respect to the Alterations; (iii) supervision by Landlord's
representative of the Alterations; and (iv) in the case of any Alterations
having a cost of $100,000.00 or more, delivery to Landlord of payment and
performance bonds naming Landlord and Mortgagee as obligees. The Alterations
shall conform to the requirements of Landlord's and Tenant's insurers and of the
Federal, state and local governments having jurisdiction over the Premises,
shall be performed in accordance with the terms and provisions of this Lease in
a good and workmanlike manner befitting a first class office building and shall
not adversely affect the value, utility or character of the Premises. If the
Alterations are not performed as herein required, Landlord shall have the right,
at Landlord's option, to halt any further Alterations, or to require Tenant to
perform the Alterations as herein required or to require Tenant to return the
Premises to its condition before such Alterations. Notwithstanding the
foregoing, if any mechanic's or materialmen's lien is filed against the
Premises, the Building or the Land for work claimed to have been done for, or
materials claimed to have been furnished to or for the benefit of, Tenant, such
lien shall be discharged of record by Tenant within ten (10) days by the payment
thereof or the filing of any bond required by law. If Tenant shall fail to
discharge any such lien, Landlord may (but shall not be obligated to) discharge
the same, the cost of which shall be paid by Tenant within three (3) days of
demand by Landlord. Such discharge by Landlord shall not be deemed to waive or
release the default of Tenant in not discharging the same. Neither Landlord's
consent to the Alterations nor anything contained in this Lease shall be deemed
to be the agreement or consent of Landlord to subject Landlord's interest in the
Premises, the Building or the Land to any mechanic's or materialmen's liens
which may be filed in respect of the Alterations.

     13.3  REMOVAL OF ALTERATIONS.  Except to the extent Tenant requests and
Landlord designates otherwise at 
<PAGE>
 
the time Landlord approves such Alterations, all or any part of the Alterations
(including, without limitation, wall-to-wall carpet and wiring), whether made
with or without the consent of Landlord, shall, at the election of Landlord,
either be removed by Tenant at its expense before the expiration of the Term or
shall remain upon the Premises and be surrendered therewith at the Expiration
Date or earlier termination of this Lease as the property of Landlord without
disturbance, molestation or injury. If Landlord requires the removal of all or
part of the Alterations, Tenant, at its expense, shall repair any damage to the
Premises or the Building caused by such removal. If Tenant fails to remove the
Alterations upon Landlord's request, then Landlord may (but shall not be
obligated to) remove the same and the cost of such removal and repair of any
damage caused by the same, together with any and all damages which Landlord may
suffer and sustain by reason of the failure of Tenant to remove the same, shall
be charged to Tenant and paid upon demand.

     13.4  LANDLORD ALTERATIONS.  Landlord shall have no obligation to make any
           --------------------
Alterations in or to the Premises, the Building, the Common Area or the Land
except as specifically provided in the Work Agreement. Landlord hereby reserves
the right, from time to time, to make Alterations to the Building, change the
Building dimensions, erect additional stories thereon and attach other buildings
and structures thereto, and to erect such scaffolding and other aids to
construction as Landlord deems appropriate, and no such Alterations, changes,
construction or erection shall constitute an eviction, constructive or
otherwise, or permit Tenant any abatement of Rent or claim. Notwithstanding the
foregoing, Landlord agrees that it shall not exercise any of the rights reserved
to Landlord pursuant to this Section 13.4 in a manner as shall materially
adversely affect the ability of Tenant to use the Premises for the Permitted

     No sign, advertisement or notice shall be inscribed, painted, affixed,
placed or otherwise displayed by Tenant on any part of the Land or the outside
or the inside (including, without limitation, the windows) of the Building or
the Premises. Any permitted signs shall be installed and maintained by Landlord
at Tenant's sole expense. If any prohibited sign, advertisement or notice is
nevertheless exhibited by Tenant, Landlord shall have the right to remove the
same, and Tenant shall pay any and all expenses incurred by Landlord in such
removal, together with interest thereon at the Interest Rate, upon demand.
Landlord shall have the right to prohibit any sign, advertisement, notice or
statement to the public by Tenant which, in Landlord's opinion, tends to impair
the reputation of the Building or its desirability as a first class office
building. Notwithstanding the foregoing, Tenant shall have the right, at its
sole cost and expense, to exhibit its corporate name, in a manner satisfactory
to Landlord, in Landlord's reasonable opinion, on the suite entry door of the
Premises and on a pedestal sign supplied by Landlord to be located in front of
the Premises.

Premises or the Building caused by moving the property of Tenant into or out of
the Premises, or due to the same being on the Premises, shall be repaired by
Landlord, at the expense of Tenant. Tenant shall promptly remove from the Common

     15.2  INSTALLING AND OPERATING TENANT'S EQUIPMENT.  Without first obtaining
           -------------------------------------------
the written consent of Landlord, Tenant shall not install or operate in the
Premises any equipment which causes the floor load to exceed the load limit set
by Landlord for the Building. The floor load limit set by Landlord for the
Building is, as of the Date of Lease, 125 pounds per square foot. Machines and
equipment which cause noise or vibration that may be transmitted to the
structure of the Building or to any space therein so as to be objectionable to
Landlord or any other Building tenant shall be installed and maintained by

no notice shall be required), to enter the Premises, without charge therefor to
Landlord and without diminution of Rent: (i) to examine, inspect and protect the
Premises and the Building; (ii) to make such alterations and repairs or perform
such maintenance which in the sole judgment of Landlord may be deemed necessary

Building or to present or future Mortgagees; or (iv) to exhibit the same to
prospective tenants during the last nine (9) months of the Term.

                                   INSURANCE

     17.1  INSURANCE RATING.  Tenant shall not conduct or permit any activity,
           ----------------
or place any equipment or material, in or about the Premises, the Building or
the Common Area which will increase the rate of fire or other insurance on the
Building or insurance benefitting any other tenant of the Building; and if any
increase in the rate of insurance is stated by any insurance company or by the
applicable insurance rating bureau to be due to any activity, equipment or
material of Tenant in or about the Premises, the Building or the Common Area,
such statement shall be conclusive evidence that the increase in such rate is
due to the same and, as a result thereof, Tenant shall pay such increase to
Landlord upon demand.



     17.2  LIABILITY INSURANCE.  Tenant shall, at its sole cost and expense,
           -------------------  
procure and maintain throughout the Term a commercial general liability policy
insuring against claims, demands or actions for bodily injury, death, personal
injury, and loss or damage to property arising out of or in connection with: (i)
the Premises; (ii) the condition of the Premises; (iii) Tenant's operations in,
maintenance and use of the Premises, Building and Common Area; and (iv) Tenant's
liability assumed under this Lease. Such insurance shall have such combined
single limit as reasonably required by Landlord from time to time, but in no
event less than Two Million Dollars ($2,000,000.00) per occurrence, on an
occurrence basis, and shall be primary over any insurance carried by Landlord.
Endorsements shall be obtained for cross-liability and contractual liability.

     17.3  INSURANCE FOR PERSONAL PROPERTY.  Tenant shall, at its sole cost and
           -------------------------------
expense, procure and maintain throughout the Term a property insurance policy
(written on an "All Risk" basis) insuring all of Tenant's personal property,
including but not limited to equipment, furniture, fixtures, furnishings and
leasehold improvements which are the responsibility of Tenant, for not less than
the full replacement cost of said property. All proceeds of such insurance shall
be used to repair or replace Tenant's property. In addition, Tenant shall, at
its sole cost and expense, procure and maintain business interruption insurance
in an amount not less than the Base Rent due hereunder for the first (1st) Lease
Year.

     17.4  REQUIREMENTS OF INSURANCE COVERAGE.  All such insurance required to
           ----------------------------------
be carried by Tenant herein shall be with an insurance company licensed to do
business in the Commonwealth of Virginia and rated not lower than A-XII in the
A.M. Best Rating Guide. Such insurance (i) shall contain an endorsement that
such policy shall remain in full force and effect notwithstanding that the
insured has released its right of action against any party before the occurrence
of a loss; (ii) shall name Landlord and, at Landlord's request, any Mortgagee or
ground lessor, as additional insured parties; and (iii) shall provide that the
policy shall not be cancelled, failed to be renewed or materially amended
without at least thirty (30) days' prior written notice to Landlord and, at
Landlord's request, any Mortgagee. On or before the Commencement Date and,
thereafter, not less than thirty (30) days before the expiration date of the
insurance policy, an original of the policy (including any renewal or
replacement policy) or a certified copy thereof, together with 

                                       16
<PAGE>
 
evidence satisfactory to Landlord of the payment of all premiums for such
policy, shall be delivered to Landlord and, at Landlord's request, to any
Mortgagee.

     17.5  WAIVER OF SUBROGATION.  Each party hereby releases the other party
           ---------------------
hereto from liability for any loss or damage to any building, structure or
tangible personal property, or any resulting loss of income, or losses under
worker's compensation laws and benefits, notwithstanding that such loss, damage
or liability may arise out of the negligent or intentionally tortious act or
omission of the other party or its Agents, if such loss or damage is covered by
insurance benefitting the party suffering such loss or damage or was required to
be covered by insurance pursuant to this Lease. Each party hereto shall use
reasonable efforts to have a waiver of subrogation clause (providing that such
waiver of right of recovery against the other party shall not impair the
effectiveness of such policy or the insured's ability to recover thereunder)
included in its said policies, and shall promptly notify the other in writing if
such clause cannot be included in any such policy; if such waiver of subrogation
clause shall not be available, then the foregoing waiver of right of recovery
shall be void.

     17.6  SECURITY.  In the event that Landlord engages the services of a
           --------
professional security system for the Building, it is understood that such
engagement shall in no way increase Landlord's liability for occurrences and/or
consequences which such a system is designed to detect or avert and that Tenant
shall look solely to its insurer as set out above for claims for damages or
injury to any person or property.

     17.7  LANDLORD'S INSURANCE.  Landlord shall procure and maintain throughout
           --------------------
the Term fire and extended coverage insurance on the Building in such coverage
and amounts as reasonably determined by Landlord in its prudent management of
the Building and as necessary to satisfy the requirements of Landlord's
Mortgagee, if any.

                        LANDLORD SERVICES AND UTILITIES

     18.1  ORDINARY SERVICES TO THE PREMISES.  Landlord agrees to furnish
           ---------------------------------
landscaping and grounds maintenance and snow clearing for the areas used in
common by the tenants of the Building or the Park. The foregoing services shall
be furnished by Landlord and reimbursed by Tenant as part of PCAM; provided,
however, that Landlord shall be under no responsibility or liability for failure
or interruption in such services caused by breakage, accident, strikes, repairs
or for any other cause or causes beyond the control of Landlord, nor in any
event for any indirect or consequential damages; and failure or omission on the
part of Landlord to furnish such service shall not be construed as an eviction
of Tenant, nor work an abatement of Rent, nor render Landlord liable in damages,
nor release Tenant from prompt fulfillment of any of the covenants under this
Lease. Notwithstanding anything to the contrary set forth elsewhere in this
Lease, Tenant shall have the right, at all times during the Term, on a 24-hour a
day, 365-day a year basis, to operate and control the heating, ventilating and
air conditioning systems serving the Premises.

     18.2  UTILITY CHARGES.  All telephone, electricity, gas, heat and other
           ---------------
utility service furnished to the Premises shall be paid for by Tenant except to
the extent the cost of same is included within PCAM or BOE. Landlord reserves
the right separately to meter or monitor the utility services provided to the
Premises. The cost of any such meter shall be borne by Tenant.

                             LIABILITY OF LANDLORD

     19.1  NO LIABILITY.  Except where due to Landlord or its Agents' gross
           ------------
negligence or willful misconduct, Landlord and its Agents shall not be liable to
Tenant or its Agents for, and Tenant, for itself and its Agents, does hereby
release Landlord and its Agents from liability for, any damage, compensation or
claim arising from: (i) the necessity of repairing any portion of the Premises
or the Building or the Common Area or any structural defects thereto; (ii) any

                                       17
<PAGE>
 
interruption in the use of the Premises or the Common Area for any reason
including any interruption or suspension of utility service; (iii) fire or other
casualty or personal or property injury, damage or loss resulting from the use
or operation (by Landlord, Tenant, or any other person whomsoever) of the
Premises or the Building or the Common Area; (iv) the termination of this Lease;
(v) robbery, assault or theft; or (vi) any leakage in the Premises or the
Building from water, rain, snow or other cause whatsoever. No such occurrence
shall give rise to diminution or abatement of Rent or constructive eviction.
Notwithstanding the foregoing, any goods, automobiles, property or personal
effects stored or placed by Tenant or its Agents in or about the Premises, the
Building or the Common Area shall be at the sole risk of Tenant; Tenant hereby
expressly waives its right to recover against Landlord and its Agents therefor.
Tenant hereby waives any claim it might have against Landlord or its Agents for
any consequential damages or business losses sustained by Tenant arising out of
the loss or damage to any person or property of Tenant, or any interruption in
the use of the Premises or the Common Area, for any reason. Tenant acknowledges
its obligation to insure against such losses and damages.

     19.2  INDEMNITY OF TENANT IN FAVOR OF LANDLORD.  Tenant shall indemnify,
           ----------------------------------------
defend, protect and hold Landlord and its Agents harmless from and against any
and all damages, claims, liabilities, costs or expenses (including, without
limitation, the reasonable fees of attorneys or other professionals) of every
kind and nature (including, without limitation, those arising from any injury or
damage to any person, property or business) incurred by or claimed against
Landlord or its Agents, directly or indirectly, as a result of, arising from or
in connection with: (i) Tenant's or its Agents' use and occupancy of the
Premises, the Building or the Common Area; (ii) Tenant's breach of any provision
of this Lease; or (iii) any act, omission or negligence of Tenant or its Agents;
provided, however, that the foregoing obligations of Tenant to indemnify
Landlord and its Agents shall not apply in the instance of any negligence of
willful misconduct on the part of Landlord or any of its Agents.

     19.3  INDEMNITY OF LANDLORD IN FAVOR OF TENANT.  Landlord shall indemnify,
           ----------------------------------------
defend, protect and hold Tenant harmless from and against any and all damages,
claims, liabilities, costs or expenses (including, without limitation, the
reasonable fees of attorneys or other professionals) of every kind and nature
incurred by or claimed against Tenant, directly or indirectly, as a result of,
arising from or in connection with Landlord's breach of any provision of this
Lease; provided, however, that the foregoing obligation of Landlord to indemnify
Tenant shall not apply in the instance of any negligence or willful misconduct
on the part of Tenant or any of its Agents.

                                  ARTICLE 20
                             RULES AND REGULATIONS

     Tenant and its Agents shall at all times abide by and observe the Rules and
Regulations and any amendments thereto that may be promulgated from time to time
by Landlord for the operation and maintenance of the Building and the Common
Area and the Rules and Regulations shall be deemed to be covenants of the Lease
to be performed and/or observed by Tenant.  Nothing contained in this Lease
shall be construed to impose upon Landlord any duty or obligation to enforce the
Rules and Regulations, or the terms or provisions contained in any other lease,
against any other tenant of the Building.  Landlord shall not be liable to
Tenant for any violation by any party of the Rules and Regulations or the terms
of any other Building lease.  If there is any inconsistency between this Lease
and the Rules and Regulations, this Lease shall govern.  Landlord reserves the
right to amend and modify the Rules and Regulations as it deems necessary.

                                  ARTICLE 21
                             DAMAGE; CONDEMNATION

     21.1  DAMAGE TO THE PREMISES.  If the Premises shall be damaged by fire or
           ----------------------
other cause without the fault or negligence of Tenant or its Agents, Landlord
shall diligently and as soon as practicable after such damage occurs (taking
into account the time necessary to effect a satisfactory settlement with any
insurance company involved) repair such damage at the expense of Landlord;
provided, however, that Landlord's obligation to repair such damage shall not

                                       18
<PAGE>
 
exceed the proceeds of insurance available to Landlord (reduced by any proceeds
retained pursuant to the rights of Mortgagee). Notwithstanding the foregoing, if
the Premises or the Building is damaged by fire or other cause to such an extent
that, in Landlord's sole judgment, the damage cannot be substantially repaired
within two hundred (200) days after the date of such damage, or if the Premises
are damaged during the last two (2) Lease Years, then Landlord or Tenant within
thirty (30) days from the date of such damage may terminate this Lease by notice
to the other. If either Landlord or Tenant terminates this Lease, the Rent shall
be apportioned and paid to the date of such termination. If neither Landlord nor
Tenant so elects to terminate this Lease but the damage required to be repaired
by Landlord is not repaired within two hundred (200) days from the date of such
damage (such two hundred (200) day period of time to be extended by the period
of time of any delay outside the direct control of Landlord plus a reasonable
period of time for a satisfactory settlement with any insurance company
involved), Tenant, within thirty (30) days from the expiration of such two
hundred (200) day period of time (as the same may be extended), may terminate
this Lease by notice to Landlord. During the period of time that Tenant is
deprived of the use of the damaged portion of the Premises, and provided such
damage is not the consequence of the fault or negligence of Tenant or its
Agents, Base Rent and Tenant's Proportionate Share shall be reduced by the ratio
that the rentable square footage of the Premises damaged bears to the total
gross rentable square footage of the Premises before such damage. All injury or
damage to the Premises or the Building resulting from the fault or negligence of
Tenant or its Agents shall be repaired by Tenant, at Tenant's expense, and Rent
shall not abate. If Tenant shall fail to do so or if Landlord shall so elect,
Landlord shall have the right to make such repairs, and any expense so incurred
by Landlord, together with interest thereon at the Interest Rate, shall be paid
by Tenant upon demand. Notwithstanding anything herein to the contrary, Landlord
shall not be required to rebuild, replace or repair any non-standard tenant
improvements, tenant extras or Alterations or any personal property of Tenant.

     21.2  CONDEMNATION.  If the whole or a Substantial Part of the Premises or
           ------------
the Building shall be taken or condemned by any governmental or quasi-
governmental authority for any public or quasi-public use or purpose (including,
without limitation, sale under threat of such a taking), then the Term shall
cease and terminate as of the date when title vests in such governmental or
quasi-governmental authority, and Rent shall be prorated to the date when title
vests in such governmental or quasi-governmental authority. If less than a
Substantial Part of the Premises is taken or condemned by any governmental or
quasi-governmental authority for any public or quasi-public use or purpose
(including, without limitation, sale under threat of such a taking), Base Rent
and Tenant's Proportionate Share shall be reduced by the ratio that the portion
so taken bears to the rentable square footage of the Premises before such
taking, effective as of the date when title vests in such governmental or quasi-
governmental authority, and this Lease shall otherwise continue in full force
and effect. Tenant shall have no claim against Landlord (or otherwise) as a
result of such taking, and Tenant hereby agrees to make no claim against the
condemning authority for any portion of the amount that may be awarded as
compensation or damages as a result of such taking; provided, however, that
Tenant may, to the extent allowed by law, claim an award for moving expenses and
for the taking of any of Tenant's property (other than its leasehold interest in
the Premises) which does not, under the terms of this Lease, become the property
of Landlord at the termination hereof, as long as such claim is separate and
distinct from any claim of Landlord and does not diminish Landlord's award.
Tenant hereby assigns to Landlord any right and interest it may have in any
award for its leasehold interest in the Premises.

                                    DEFAULT

     22.1  EVENTS OF DEFAULT.  Each of the following shall constitute an Event
           -----------------
of Default: (i) Tenant fails to pay Rent within five (5) days after notice from
Landlord; provided that no such notice shall be required if at least two such
notices shall have been given during the same Lease Year; (ii) Tenant fails to
observe or perform any other term, condition or covenant herein binding upon or
obligating Tenant within twenty (20) days after notice from Landlord; (iii)
Tenant abandons or vacates the Premises; (iv) Tenant makes or consents to a
general assignment for the benefit of creditors or a common law composition of
creditors, or a receiver of the Premises or all or substantially all of the
assets of Tenant is appointed, or (v) Tenant files a voluntary petition in any
bankruptcy or insolvency proceeding, or an 

                                       19
<PAGE>
 
involuntary petition in any bankruptcy or insolvency proceeding is filed against
Tenant and is not discharged by Tenant within sixty (60) days.

     22.2  LANDLORD'S REMEDIES.  Upon the occurrence of an Event of Default,
           -------------------
Landlord, at its option, without further notice or demand to Tenant, may in
addition to all other rights and remedies provided in this Lease, at law or in
equity:

           (a)  Terminate this Lease and Tenant's right of possession of the
Premises, and recover all damages to which Landlord is entitled under law,
specifically including, but without limitation, all of Landlord's expenses of 
re-letting (including, without limitation, rental concessions to new tenants,
repairs, Alterations, legal fees and brokerage commissions). If Landlord elects
to terminate this Lease, every obligation of the parties shall cease as of the
date of such termination, except that Tenant shall remain liable for payment of
Rent and performance of all other terms and conditions of this Lease to the date
of termination.

           (b)  Terminate Tenant's right of possession of the Premises without
terminating this Lease, in which event Landlord may, but shall not be obligated
to, re-let the Premises, or any part thereof, for the account of Tenant, for
such rent and term and upon such other conditions as are acceptable to Landlord.
For purposes of such re-letting, Landlord is authorized to redecorate, repair,
alter and improve the Premises to the extent necessary in Landlord's sole
discretion. Until Landlord re-lets the Premises, Tenant shall remain obligated
to pay Rent to Landlord as provided in this Lease. If and when the Premises are
re-let and if a sufficient sum is not realized from such re-letting after
payment of all Landlord's expenses of re-letting (including, without limitation,
rental concessions to new tenants, repairs, Alterations, legal fees and
brokerage commissions) to satisfy the payment of Rent due under this Lease for
any month, Tenant shall pay Landlord any such deficiency upon demand. Tenant
agrees that Landlord may file suit to recover any sums due Landlord under this
Section from time to time and that such suit or recovery of any amount due
Landlord shall not be any defense to any subsequent action brought for any
amount not previously reduced to judgment in favor of Landlord.

           (c)  Terminate this Lease and Tenant's right of possession of the
Premises, and recover from Tenant the net present value of the Rent due from the
date of termination until the Expiration Date, discounted at the lesser of the
Interest Rate as of the date of termination or seven percent (7%) per annum.

           (d)  Re-enter and repossess the Premises and remove all persons and
effects therefrom, by summary proceeding, ejectment or other legal action or by
using such force as may be necessary. Landlord shall have no liability by reason
of any such re-entry, repossession or removal.

           (e)  Recover from Tenant, to the extent permitted under the laws of
the Commonwealth of Virginia, the value and/or cost of all concessions to Tenant
under this Lease.

     22.3  RIGHTS UPON POSSESSION.  If Landlord takes possession pursuant to
           ----------------------
this Article, with or without terminating this Lease, Landlord may, at its
option, enter into the Premises, remove Tenant's Alterations, signs, personal
property, equipment and other evidences of tenancy, and store them at Tenant's
risk and expense or dispose of them as Landlord may see fit, and take and hold
possession of the Premises; provided, however, that if Landlord elects to take
possession only without terminating this Lease, such entry and possession shall
not terminate this Lease or release Tenant, in whole or in part, from the
obligation to pay the Rent reserved hereunder for the full Term or from any
other obligation under this Lease or any guaranty thereof.

     22.4  NO WAIVER.  If Landlord shall institute proceedings against Tenant
           ---------
and a compromise or settlement thereof shall be made, the same shall not
constitute a waiver of any other covenant, condition or agreement herein
contained, nor of any of Landlord's rights hereunder. No waiver by Landlord of
any breach shall operate as a waiver of 

                                       20
<PAGE>
 
such covenant, condition or agreement, or operate as a waiver of such covenant,
condition or agreement itself, or of any subsequent breach thereof. No payment
of Rent by Tenant or acceptance of Rent by Landlord shall operate as a waiver of
any breach or default by Tenant under this Lease. No payment by Tenant or
receipt by Landlord of a lesser amount than the monthly installment of Rent
herein stipulated shall be deemed to be other than a payment on account of the
earliest unpaid Rent, nor shall any endorsement or statement on any check or
communication accompanying a check for the payment of Rent be deemed an accord
and satisfaction, and Landlord may accept such check or payment without
prejudice to Landlord's right to recover the balance of such Rent or to pursue
any other remedy provided in this Lease. No re-entry by Landlord, and no
acceptance by Landlord of keys from Tenant, shall be considered an acceptance of
a surrender of the Lease.

     22.5  RIGHT OF LANDLORD TO CURE TENANT'S DEFAULT.  If an Event of Default
           ------------------------------------------
shall occur, then Landlord may (but shall not be obligated to) make such payment
or do such act to cure the Event of Default, and charge the amount of the
expense thereof, together with interest thereon at the Interest Rate, to Tenant.
Such payment shall be due and payable upon demand; however, the making of such
payment or the taking of such action by Landlord shall not be deemed to cure the
Event of Default or to stop Landlord from the pursuit of any remedy to which
Landlord would otherwise be entitled. Any such payment made by Landlord on
Tenant's behalf shall bear interest until paid at the Interest Rate.

     22.6  LATE PAYMENT.  If Tenant fails to pay any Rent when due and payable,
           ------------
and such failure continues for five (5) days after notice thereof is given by
Landlord to Tenant, Tenant shall pay to Landlord a late charge of five percent
(5%) of the amount of such overdue Rent. In addition, any such late Rent payment
shall bear interest from the date such Rent became due and payable to the date
of payment thereof by Tenant at the Interest Rate. Such late charge and interest
shall be due and payable within two (2) days after written demand from Landlord.

     22.7  LANDLORD DEFAULT.  If Landlord shall fail to keep or perform any of
           ----------------
its obligations under this Lease, then Tenant may (but shall not be obligated to
do so) upon the continuance of such failure on Landlord's part for twenty (20)
days after Landlord's receipt of notice from Tenant specifying the failure (or,
in the case of any such failure which cannot with due diligence be cured within
twenty (20) days, within such additional period, if any, as may be reasonably
required by Landlord to cure such failure with due diligence), and without
waiving or releasing Landlord from any obligation, make such payment or perform
such obligation and all sums so paid by Tenant and all necessary and incidental
costs and expenses, including reasonable attorney's fees paid to independent
legal counsel, incurred by Tenant in making such payment or performing such
obligation, together with interest thereon at the Interest Rate from the date of
payment, shall be paid by Landlord to Tenant on demand, and if not so paid by
Landlord, Tenant shall have the right to pursue any legal remedies available to
it to collect payment, but shall not be entitled to offset such payment against
Rent thereafter payable under this Lease.

                                  ARTICLE 23
                                   MORTGAGES

       23.1  SUBORDINATION.  This Lease is subject and subordinate to all ground
             -------------
or underlying leases and to any first Mortgage(s) which may now or hereafter
affect such leases or the Land and to all renewals, modifications,
consolidations, replacements and extensions thereof. This subordination shall be
self-operative; however, in confirmation thereof, Tenant shall execute promptly
any instrument that Landlord or any first Mortgagee may request confirming such
subordination. Tenant hereby constitutes and appoints Landlord as Tenant's
attorney-in-fact to execute any such instrument on behalf of Tenant.
Notwithstanding the foregoing, before any foreclosure sale under a Mortgage, the
Mortgagee shall have the right to subordinate the Mortgage to this Lease, and,
in the event of a foreclosure, this Lease may continue in full force and effect
and Tenant shall attorn to and recognize as its landlord the purchaser of
Landlord's interest under this Lease. Tenant shall, upon the request of a
Mortgagee or purchaser at foreclosure, execute, acknowledge and deliver any
instrument that has for its purpose and effect the subordination of the lien of
any Mortgage 

                                       21
<PAGE>
 
to this Lease or Tenant's attornment to such Purchaser.

     23.2  MORTGAGEE PROTECTION . Tenant agrees to give any Mortgagee by
           --------------------
certified mail, return receipt requested, a copy of any notice of default served
upon Landlord, provided that before such notice Tenant has been notified in
writing of the address of such Mortgagee. Tenant further agrees that if Landlord
shall have failed to cure such default within the time provided for in this
Lease, then Mortgagee shall have an additional thirty (30) days within which to
cure such default; provided, however, that if such default cannot be reasonably
cured within that time, then such Mortgagee shall have such additional time as
may be necessary to cure such default so long as Mortgagee has commenced and is
diligently pursuing the remedies necessary to cure such default (including,
without limitation, the commencement of foreclosure proceedings, if necessary),
in which event this Lease shall not be terminated or Rent abated while such
remedies are being so diligently pursued. In the event of the sale of the Land
or the Building, by foreclosure or deed in lieu thereof, the Mortgagee or
purchaser at such sale shall be responsible for the return of the Security
Deposit only to the extent that such Mortgagee or purchaser actually received
the Security Deposit.

     23.3  MODIFICATION DUE TO FINANCING.  If, in connection with obtaining
           -----------------------------
construction or permanent financing for the Premises, the Building or the Land,
any lender (or Mortgagee) shall request reasonable modifications of this Lease
as a condition to such financing, Tenant shall promptly execute a modification
of this Lease, provided such modifications do not materially increase the
financial obligations of Tenant hereunder or materially adversely affect the
leasehold interest hereby created or Tenant's reasonable use and enjoyment of
the Premises. Tenant shall prior to execution and throughout the Term, upon
request from time to time, provide such financial information and documentation
about itself to Landlord or Mortgagee as may be requested.

     23.4  NON-DISTURBANCE.  Landlord agrees to utilize its reasonable efforts
           ---------------
to obtain from any Mortgagee under any Mortgage recorded as of or after the Date
of Lease and encumbering the Premises an agreement in writing, on the standard
form for such agreement employed by such Mortgagee, providing in substance that
so long as Tenant shall not be in default with respect to, and shall faithfully
discharge, the obligations on its part to be kept and performed under the terms
of this Lease, its tenancy shall not be disturbed. Tenant hereby acknowledges
that the decision by any such Mortgagee holding a Mortgage encumbering the
Premises to grant such non-disturbance protection to Tenant is a determination
that will be made by such Mortgagee and is not within the control of Landlord.
Tenant agrees to cooperate fully with Landlord in connection with Landlord's
efforts to obtain such non-disturbance protection for Tenant, and in such
regard, Tenant shall supply to Landlord and such Mortgagee, if requested,
Tenant's most recent audited financial statements and unaudited financial
statements prepared by Tenant for the period following that period reflected in
Tenant's most recent audited financial statements, with such unaudited financial
statements being certified as true and accurate by Tenant's chief financial
officer to the best of his knowledge.

the Commonwealth of Virginia. Tenant shall indemnify Landlord against all
liabilities and damages sustained by Landlord by reason of such retention of
possession.

through or under Landlord, subject to the provisions of this Lease and any
Mortgage to which this Lease is subordinate and easements, conditions and
restrictions of record affecting the Land.

or assignees (which consent shall include the approval by Landlord set forth in
this Section 26.2 of Tenant's storage and use of diesel fuel for the back-up

           ------
in or under the Premises, the Building, the Land or the Park and any
governmental agency or entity having jurisdiction over the Premises, the

Tenant shall be responsible for removing those Hazardous Materials arising out
of or related to the use or occupancy of the Premises by Tenant or its Agents,
affiliates, sublessees or assignees but not those of its predecessors.
Notwithstanding the foregoing, Tenant shall not take any remedial action in or
about the Premises, the Building, the Land or the Park, nor enter into any
settlement agreement, consent decree or other compromise with respect to any
claims relating to any Hazardous Material in any way connected with the
Premises, the Building, the Land or the Park, without first notifying Landlord
of Tenant's intention to do so and affording Landlord the opportunity to appear,
intervene or otherwise appropriately assert and protect Landlord's interest with
respect thereto. Tenant immediately shall notify Landlord in writing of: (i) any
spill, release, discharge or disposal of any Hazardous Material in, on or under

of the availability or impending availability for lease of that certain space,
comprising approximately 13,745 gross rentable square feet, designated as Suite

in the aggregate amount of space in the Park demised by Landlord to Tenant as a
result of the leasing by Tenant from Landlord of the Offer Space; and (v) the
term pursuant to which the Offer Space shall be leased by Tenant from Landlord
shall commence on the date set forth for such commencement in the notice given
by Landlord to Tenant and shall end on the Expiration Date. Tenant shall have
five (5) business days from the date of such notice from Landlord to notify
Landlord that Tenant intends to enter into an amendment to this Lease with

Provided that Tenant shall have given the notice described in the preceding
sentence to Landlord before the expiration of such five (5) business day period
of time, Tenant shall have fifteen (15) business days from the date of such
notice from Landlord to enter into an amendment to this Lease with Landlord so
as to include the Offer Space on such terms and conditions. If Tenant does not
give notice of its intention to enter into such amendment with Landlord as
aforesaid or does not enter into such amendment as aforesaid with Landlord,
Landlord shall have the right to enter into a lease with any third party for the
Offer Space on any terms and conditions as upon which Landlord and such third
party shall agree. The rights extended in this Section 27.22 to Tenant by
Landlord are exclusively granted by Landlord to the original Tenant named under
this Lease, Exodus Communications, Inc., and shall not inure to the benefit of
or be exercisable by any party other than the original Tenant named under this

shall: (a) terminate automatically upon the issuance of any notice of default by
Landlord to Tenant with respect to any of Tenant's obligations under this Lease;
(b) terminate automatically upon the failure of Tenant to have given notice to
Landlord of its intention to enter into an amendment of this Lease with Landlord
on the terms and conditions set forth in the preceding provisions of this
Section 27.22 within five (5) business days after the date of the giving by
Landlord of notice to Tenant with respect to the availability of Offer Space;

amendment to this Lease with Landlord on the terms and conditions set forth in
the preceding provisions of this Section 27.22 within fifteen (15) business days
after the date of the giving by Landlord of notice to Tenant with respect to the
availability of Offer Space; (d) terminate automatically as of October 1, 1997
unless on or prior to such date Tenant shall have exercised its rights under
this Section 27.22 to lease the Offer Space; and (e) be subject and subordinate,
in all respects and at all times, to any and all Preferential Rights (herein
defined) applicable to the Offer Space or any portion thereof, or to any other
space in the Building of which the Offer Space or any portion thereof shall be a
part, extended by Landlord (or any predecessor-in-interest to Landlord) prior to
the date of this Lease for the benefit of any existing tenant or occupant of the
Building. For purposes hereof, "Preferential Rights" means all rights of
renewal, rights of first refusal, rights of first offer, rights to expansion
space or any other rights or agreements similar or dissimilar to the foregoing
concerning the future or potential leasing of the Offer Space or any portion
thereof or any other space in the Building of which the Offer Space or any
portion thereof shall be a part. Notwithstanding anything to the contrary set
forth elsewhere in this Section 27.22, Tenant acknowledges and agrees that all
of the rights granted to it with respect to the Offer Space pursuant to this
Section 27.22 are subject and subordinate, in all respects, to the Preferential
Rights with respect to the Offer Space granted by Landlord to another tenant of
the Park, Value Health Sciences, Inc., pursuant to, and in accordance with, the
lease agreement in effect as of the Date of Lease between Landlord and Value
Health Sciences, Inc. Furthermore, Tenant acknowledges and agrees that Landlord

          "Tenant's Representative") with full power and authority to bind
          Tenant for all actions taken with regard to the Tenant Improvements.
          Tenant hereby ratifies all actions and decisions with regard to the
          Tenant Improvements that Tenant's Representative may have taken or
          made prior to the execution of this Work Agreement.  Landlord shall
          not be obligated to respond to or act upon any plan, drawing, change

          -------------------                                                 
          (herein defined) in accordance with the Tenant Improvements Drawings
          and Specifications (as defined below).  The Tenant Improvements

          Landlord shall advise Tenant, in writing, of the name of at least one
          (1) general contractor with whom Landlord has had satisfactory
          experience in the past and which Landlord believes to have expertise
          in connection with the construction of alterations and improvements

          Landlord, upon execution and delivery of same, a photocopy of the full
          and complete contract made between the Tenant's General Contractor and
          Tenant with respect to the Tenant Improvements, which contract shall
          be acceptable to Landlord in all respects, in its reasonable judgment.

     2.4  Tenant's Construction Manager.  Landlord and Tenant hereby agree that
          -----------------------------                                        
          Tenant shall employ a construction manager in connection with the
          construction and installation of the Tenant Improvements (the
          "Tenant's Construction Manager"). If Tenant's Construction Manager
          shall not be an employee of Tenant, Tenant shall promptly supply to
          Landlord, upon execution and delivery of the same, a photocopy of the
          full and complete contract made between the Tenant's Construction
          Manager and Tenant with respect to the Tenant Improvements, which

          Tenant's Construction Manager and its services shall be paid by
          Tenant, at the sole cost and expense of Tenant.

     2.5  Landlord's Construction Manager.  Landlord and Tenant hereby agree
          -------------------------------                                   
          that Landlord shall have the right, at the sole option of Landlord, to
          employ a construction manager (the "Landlord's Construction Manager")
          in connection with the supervision of the construction and
          installation of the Tenant Improvements.  All costs and expenses of
          the Landlord's Construction Manager shall be paid by Landlord, at its
          sole cost and expense.

     2.6  Payment of Costs of Tenant Improvements.  Each and all of the costs of
          ---------------------------------------

          direct costs of construction, all architectural, engineering and
          planning fees, the costs of all building and other governmental
          permits, and all other soft or indirect costs of construction of any
          kind whatsoever) shall be paid by Tenant, at Tenant's sole cost and
          expense.

3.   Tenant Improvements Drawings and Specifications.  Within five (5) business
     -----------------------------------------------                           
     days after Landlord receives detailed construction drawings and
     specifications for the Tenant Improvements from Tenant's Architect,
     Landlord shall either approve or disapprove the same, such approval not to
     be unreasonably withheld, conditioned or delayed, except that Landlord
     shall have the right, in its sole discretion, to approve or disapprove any
     portions of the Tenant Improvements which, in the sole opinion of Landlord,
     have an adverse effect upon the structural integrity of the Building or the
     heating, ventilating, air conditioning, plumbing, electrical, and other
     mechanical systems serving the Premises. In the event of a disapproval by
     Landlord (except in the case of a disapproval by Landlord arising in
     connection with Landlord's concerns regarding the structural integrity of
     the Building or the various systems serving the Premises, as aforesaid),
     Landlord shall require, and Tenant shall make, the minimum changes
     necessary to such plans and specifications in order to correct or to
     address the concerns of Landlord, and Tenant's Architect shall return the
     drawings and specifications to Landlord for its review again, which
     Landlord shall approve or disapprove within five (5) business days after
     Landlord receives the revised plans and specifications. The aforedescribed
     procedure shall be repeated until such plans and specifications are finally
     approved by Landlord and written approval has been delivered to and
     received by Tenant. Notwithstanding the foregoing, Landlord shall have
     complete discretion with regard to granting or withholding approval of any
     such drawings and specifications to the extent they impact the Building's
     structure or systems or would be visible from the exterior of the Building
     or any Common Area within the Building. The detailed construction drawings
     and specifications for the Tenant Improvements, as submitted by Tenant and
     approved by Landlord in accordance with the terms and conditions of this
     Section 3, are sometimes in this Work Agreement referred to as the "Tenant
     Improvements Drawings and Specifications". Any changes, additions or
     modifications that Tenant desires to make to the Tenant Improvements
     Drawings and Specifications after approval by Landlord shall also be
     subject to Landlord's prior approval, which shall not be unreasonably
     withheld, conditioned or delayed in accordance with the provisions set
     forth in the preceding provisions of this Section 3, except as provided
     above for Building structure, system or appearance impact.

4.   Construction of Tenant Improvements.
     -----------------------------------

          -------                                                       
          Complete (as defined below) the Tenant 

                                      B-2
<PAGE>
 
          Improvements on or before September 30, 1997, but neither the validity
          of this Lease nor any of the monetary or other obligations of Tenant
          under this Lease shall be affected in any way by a failure to
          Substantially Complete the Tenant Improvements by such date.

     4.2  Construction of Tenant Improvements.  Prior to the commencement of
          -----------------------------------                               
          construction of the Tenant Improvements, Tenant shall:  (a) obtain the
          approval of Landlord to the Tenant Improvements Drawings and
          Specifications, as set forth above; (b) obtain, at the sole cost and
          expense of Tenant,  all building and other permits required to be
          issued in connection with the construction of the Tenant Improvements;
          (c) supply to Landlord, at Landlord's option but at the sole cost and
          expense of Tenant, payment and performance bonds naming Landlord as an
          obligee with respect to the construction contract for completion of
          the Tenant Improvements, each of such bonds being in an amount not
          less than the maximum amount of the construction contract made between
          Tenant and Tenant's General Contractor; and (d) provide, at the sole
          cost and expense of Tenant, to Landlord such builder's risk,
          liability, property damage and other insurance, covering Landlord,
          Tenant, Tenant's General Contractor and such other parties as Landlord
          shall reasonably deem necessary, in such amounts and with such
          coverages as Landlord, in its reasonable judgment, shall require.  The
          Tenant Improvements shall be constructed by Tenant with new, first
          class materials, as typically employed in the construction of first
          class office buildings, and by skilled workmen.  Upon Substantial
          Completion of the Tenant Improvements, Tenant shall supply to Landlord
          fully executed waivers of liens from the Tenant's General Contractor
          and each of the subcontractors employed by Tenant's General Contractor
          in connection with the Tenant Improvements.  In the event that any
          mechanics' or materialmen's lien shall be filed against the Property
          in connection with, or as a result of, the construction of the Tenant
          Improvements, Tenant shall immediately cause the same to be discharged
          or bonded off, at Tenant's sole cost and expense.  Furthermore, Tenant
          shall indemnify and hold Landlord harmless from and against any and
          all losses, damages, liabilities, costs or expenses that Landlord may
          suffer or incur as a result of, or in connection with, (i) the filing
          of any mechanics' or materialsmen's liens in connection with the
          Tenant Improvements, or (ii) the making of the Tenant Improvements by
          Tenant and any of the actions or omissions of Tenant or any of the
          agents, employees or contractors of Tenant in connection therewith.

     4.3  Substantial Completion.  "Substantial Completion" of the Tenant
          ----------------------                                         
          Improvements shall be conclusively deemed to have occurred as soon as
          the Tenant Improvements have been constructed in accordance with the
          approved Tenant Improvements Drawings and Specifications and approved
          change orders, and the Tenant Improvements are ready to be utilized
          for their intended purpose, as certified by Tenant's Architect.  Upon
          Substantial Completion of the Tenant Improvements, Tenant shall supply
          to Landlord a copy of a duly issued temporary certificate of occupancy
          from the proper governmental entity having jurisdiction with respect
          thereto and, as soon as possible thereafter, shall provide to Landlord
          a photocopy of the final certificate of occupancy.  Notwithstanding
          the above, the Tenant Improvements shall be considered Substantially
          Complete and ready to be utilized for their intended purpose even
          though there remain to be completed in the Premises punch list items
          involving minor or insubstantial details of construction, decoration
          or mechanical adjustment, the lack of completion of which will not
          materially interfere with Tenant's Permitted Use of the Premises.

5.   Supplemental Power.  Landlord hereby acknowledges that as of the Date of
     ------------------                                                       
Lease the Premises is served by 800 amps, three-phase high voltage electrical
power. Tenant shall have the right, at its sole cost and expense, in connection
with the making of the Tenant Improvements or at any later time during the Term,

specifications therefor (which approval may be withheld by Landlord, in its sole
and absolute discretion), to (a) make such modifications to the electrical

electrical power serving the Premises so that Tenant may operate such machinery
and equipment as shall be necessary in connection with its business operations
at the Premises, and (b) install a back-up electrical generator in the rear of
the Building at the location shown on Exhibit A-3 attached to and hereby made a
                                      -----------                              
part of this Lease.  Landlord shall have the right, at its sole option, in
connection with Tenant's request to install any back-up electrical generator as
described above, to condition its approval thereof upon, among other things,
Tenant's construction and/or installation, at Tenant's sole cost and expense, of
such containment structures and safety systems relating thereto (including,
without limitation, containment structures and safety systems protecting against
any environmental hazards arising from Tenant's use or storage of diesel fuel
and any diesel fuel storage tank in connection therewith) as Landlord shall deem
necessary or prudent, in Landlord's sole and absolute discretion.  All such
modifications to the electrical system made by Tenant pursuant to the preceding
provisions of this Section 5, as well as any such back-up electrical generator
installed by Tenant pursuant to the preceding provisions of this Section 5,
shall be deemed to be Alterations governed by the terms and conditions of this
Lease.  Notwithstanding anything to the contrary set forth elsewhere in this
Lease, upon the written request of Landlord made at any time at or prior to the
expiration date of the Term or the sooner termination thereof in accordance with
this Lease, Tenant, at Tenant's sole cost and expense, shall remove any back-up
electrical generator installed by Tenant at the expiration of the Term or the
sooner termination thereof in accordance with this Lease.

6.   Fiber Optics Conduits.  Tenant shall have the right, at its sole cost and
     ---------------------                                                    
expense, in connection with the making of the Tenant Improvements or at any time
thereafter during the Term, but only after Landlord's review and approval of
detailed plans and specifications therefor (which approval may be withheld by
Landlord, in its sole and absolute discretion), to install and maintain in the
Park conduits, at locations approved by Landlord, in its sole and absolute
discretion, pursuant to which fiber optic lines serving the Premises may be
connected to the Building.  Tenant shall also, at all times during the Term and
at its sole cost and expense, maintain in good condition, repair and working
order, or cause to be maintained in good condition, repair and working order,
all such fiber optic lines serving the Premises.  On the expiration date of the
Term or the sooner termination thereof in accordance with this Lease, Tenant
shall, upon request by Landlord and at Tenant's sole cost and expense,
disconnect and cap any such fiber optic lines (but shall not be obligated to
remove any such lines); provided, however, if Landlord shall not request that
such fiber optic lines be disconnected and/or kept as of the termination date of
the Term or the sooner termination thereof in accordance with this Lease, all
such fiber optic lines shall become the property of Landlord at such time and
Tenant shall have no further rights or obligations with respect to such fiber
optic lines.

7.   Communications Equipment.  Tenant shall have the right, at its sole cost
     ------------------------                                                
and expense, in connection with the making of the Tenant Improvements or at any
later time during the Term, but only upon obtaining the prior written consent
thereto of Landlord (which consent may be withheld by Landlord, in its sole and
absolute discretion) after Landlord's review and approval of detailed plans and
specifications therefor (which approval may be withheld by Landlord, in its sole
and absolute discretion), to install such communications equipment in the
Premises as Tenant shall deem necessary in connection with its normal business
operations at the Premises. In connection with making its determination as to
whether to approve Tenant's request to install any such communications equipment
in the Premises, Landlord shall have the right, in its sole discretion, to take
into consideration such factors and issues as Landlord shall deem relevant,
including, without limitation, the soundness of the equipment, the safety of the
equipment and its installation, compliance by Tenant with all applicable laws,
rules and regulations, and the effect of the installation of any such equipment
upon any roof warranty. Any such communications equipment installed by Tenant
pursuant to the preceding provisions of this Section 7 shall be deemed to be
Alterations governed by the terms and conditions of this Lease. Notwithstanding
anything to the contrary set forth elsewhere in this Lease: (a) Landlord shall
have the right to disapprove the placement of any communications equipment on
the exterior of the Premises in a location that shall be

                                      B-4
<PAGE>
 
visible from the ground level of the Park; and (b) Upon the written request of
Landlord made at any time at or prior to the expiration date of the Term or the
sooner termination thereof in accordance with this Lease, Tenant, at Tenant's
sole cost and expense, shall remove any such communication equipment installed
by Tenant at the expiration date of the Term or the sooner termination thereof
in accordance with this Lease.

connection with the making of the Tenant Improvements or at any time thereafter
during the Term, but only upon obtaining the prior written consent thereto of
Landlord (which consent of Landlord shall not be unreasonably conditioned,
withheld or delayed) after Landlord's review and approval of detailed plans and
specifications therefor (which approval may be withheld by Landlord, in its sole
and absolute discretion), to install on the roof up to, but not more than, six
(6) condenser units at a location, of a size, and otherwise in a manner
satisfactory to Landlord.  Tenant shall also have the right, from time to time,
to enter upon the roof, but only after notifying Landlord of the need therefor
and obtaining Landlord's prior consent thereto, to maintain and make necessary
repairs to such condenser units, all such maintenance and repairs to be made at
the sole cost and expense of Tenant.  Notwithstanding anything to the contrary
set forth elsewhere in this Lease, (a) all such condenser units shall be placed
on the roof centerline, side-to-side, and front-to-back, so as not to be visible
from the ground level of the Park, and (b) Tenant shall employ, at Tenant's sole
cost and expense, a roofer designated by Landlord for any penetrations of the
roof of the Building required in connection with the installation of such
condenser units.  Tenant hereby acknowledges and agrees that Landlord would not
have extended the rights set forth in this Section 8 to Tenant but for the
agreement on the part of Tenant to use a roofer designated by Landlord for any
penetrations of the roof of the Building required in connection with the
installation of such condenser units.  Furthermore, Tenant acknowledges and
agrees that if that for any reason whatsoever Tenant shall utilize a roofer

below 200, Exodus agrees to charge CA a price that is the lower of thirty-three
percent (33%) of Exodus' current prices, the most favorable charge provided to
any other of its commercial and government customers or cost for similar
services. For the co-location of servers above 200, Exodus agrees to charge CA a

utilize with its clients computer software programs substantially similar in
functionality to or identical in functionality to the CA Product or Cheyenne
Products, including selling such substantially similar or identical software
into CA's confidential client base. Such programs substantially similar in
functionality to or identical to the CA Product or Cheyenne Products shall
include, but shall not be limited to, IBM's system management software,
including Tivoli, HP OpenView, Remedy, Cabletron Spectrum and SunNet Manager,
and for back-up and antivirus software products generally available from
Seagate, Legato, McAfee, Stac, Software Mogul, and Symantec (and such successor
software versions or updates). Exodus and CA agree to discuss each software
program, tool or agent used, employed or proposed to be used by Exodus at its
Exodus Sites which is substantially similar in functionality to or identical in
functionality to the CA Product or Cheyenne Products. The parties will work
together to ascertain whether the proposed product is substantially similar in
functionality to or identical in functionality to the CA Product or the Cheyenne
Products and can reasonably satisfy Exodus requirements as to functionality and
compatibility (hereinafter referred to as "substantially similar
functionality"). CA agrees to consider any suggested changes to improve, expand
or augment the functionality of the CA Product or Cheyenne Products as a result
of this functionality assessment.

      In accordance with the following Exodus agrees:

      (i)   to convert within ninety (90) days, from the provision of the
            engineer by CA to each Exodus Site, from HP OpenView and Remedy to
            Unicenter-TNG .

      (ii)  to convert within ninety (90) days of the final determination that
            Exodus' proposed product is substantially similar to or identical in
            functionality to the CA Product or Cheyenne Products for competing
            products to generally available CA Product or Cheyenne Products. At
            the end of such ninety (90) days, if Exodus has employed its best
            efforts to convert to such CA Product or Cheyenne Products and has
            been unable to complete such conversion, CA, in its sole discretion,
            shall extend the conversion time period by thirty (30) days.

      (iii) to become a CA beta test site for beta CA Product or Cheyenne
            Products, and to convert from any competing product that has been
            determined during the beta test period to be substantially similar
            to or identical in functionality to the CA Product or Cheyenne
            Products within ninety (90) days of such CA Product or Cheyenne
            Products becoming generally available.

This clause shall not prohibit Exodus from licensing computer software programs
which the parties mutually decide under this provision are not substantially
similar or are not identical in functionality to the CA Product or Cheyenne
Products.

      (b) During the term of this Agreement, Exodus agrees that it shall not
market or provide Intranet or web-based design and development services similar
to the services marketed or sold by CA to into CA's confidential client base.
<PAGE>
 
4.5   Exodus will provide CA with sales leads and support for appropriate mutual
opportunities. Exodus may provide CA with pro-sales support as deemed
appropriate in accordance with Exodus's reasonable business judgment and
discretion.

4.6   Exodus represents to CA that it and its clients are parties to a bona fide
Co-location Agreement, pursuant to the terms and conditions of Exodus' standard
agreements, under which Exodus has undertaken or will undertake the management
of client's server on behalf of client. Exodus shall ensure that no client shall
be granted access to the management stations or installation materials of the CA
Product or Cheyenne Products code installed on their machines unless such client
has procured a license from CA or an authorized CA reseller for such product(s).

5.    CA RESPONSIBILITIES

5.1   CA will use reasonable efforts to perform the joint marketing activities
set forth in Appendix G.

5.2   CA will provide Exodus with one full-time implementation engineer for each

personnel shall be managed by CA and shall work with Exodus personnel on the
implementation of the integration of the CA-Product and Cheyenne Products with
Exodus' Internet-based Co-location Services described in Appendix A. Upon mutual
agreement, these engineers will be redeployed to other Exodus locations. For
those sites which are operational at the time of execution of this Agreement by
both parties, CA will provide Exodus with such engineers within thirty (30) days
of such execution.

5.3   CA will provide Exodus with training as reasonably necessary on the CA
Product and Cheyenne Products at times and places mutually acceptable to both

parties, CA agrees to co-locate and have Exodus host all of its current and
proposed web servers at Exodus' Internet Data Site, provided that CA's client
base agrees to such co-location. Notwithstanding the foregoing, CA shall not be
obligated to co-locate and host such servers with Exodus if CA's contractually
negotiated professional services price is less than Exodus' charge for such
services.

5.6   If feasible, CA will offer excess real estate to Exodus to be used as
Exodus Sites at CA's cost and under a separate agreement to be negotiated by the
parties.

5.7   During the term of this Agreement, CA agrees not to market co-location
services into Exodus' confidential customer base.

party may disclose confidential and proprietary business or technical
information and agrees that it will not use such confidential and proprietary
business or technical information except as provided in this Agreement. As used

warrants and agrees to use its best efforts to prevent the disclosure of the
Confidential Information by its employees by taking at least such steps to
protect such Confidential Information as it takes to protect its own
Confidential Information.

12.1  This Agreement shall commence upon its Effective Date and shall continue
      for a period two years and shall thereafter automatically renew for
      additional one-year periods unless either party notifies the other of its
      intention to terminate the Agreement at least sixty (60) days prior to the
      termination date. Notwithstanding the foregoing, this Agreement may be
      terminated as follows:

      (a) By either party at any time upon sixty (60) days written notice;

      (b) By either party if the other party commits any material breach of its
      obligations hereunder and fails within sixty (60) days of written notice
      to cure the same. Any such termination shall be without prejudice to any
      other rights which may have accrued to it hereunder;

      days following filing; or

      (d) By CA, immediately in the event of a change of control of the majority
      ownership or interest or transfer to a successor corporation of the
      ownership interest of Exodus, however in its sole discretion CA may choose
      not automatically exercise such termination in every change of control
      situation. This provision may not be invoked by CA if Exodus solely
      reincorporates under the laws of Delaware.

12.2  In the event of termination of this Agreement, Exodus shall certify in
writing to CA that all copies or partial copies of the CA Product or Cheyenne
Products have been either returned to CA or otherwise destroyed and deleted from
any computer libraries or storage devices and are no longer in use by Exodus,
unless Exodus continues to license such products from CA. In such event CA shall
grant Exodus a 40% discount from CA's then prevailing Price Book or published
license fees for the CA Product and the Cheyenne Products, exclusive of usage
and maintenance, over a five year period. Continued maintenance of the CA
Product and Cheyenne Products shall be subject to CA's then prevailing annual

paid by Exodus to CA, pursuant to Section 7, for the twelve-month period
preceding the execution of such license agreement.

<PAGE>
 
LIMITED WARRANTY

  CA warrants that it can grant the license described in this Agreement and the
Order Form(s) and CA will defend or, at its option, settle any action at law
against Licensee based upon a claim that Licensee's use of the Licensed Program
in accordance with this Agreement infringes any patent, copyright or other
intellectual property right of any third party. CA also represents that the
Licensed Program will operate according to the specifications published by CA
for the Licensed Program. If it is determined that the Licensed Program does not
operate according to such Specifications, CA's only responsibility will be to
use its best efforts, consistent with industry standards, to cure the defect.

  Any warranties made by CA (other than that of noninfringement) will extend and
be in effect only for the period that Licensee is entitled to use the Licensed
Program and for which Licensee shall have paid the Usage and Maintenance Fee, if
applicable. With respect to hardware equipment supplied by CA, CA will, upon
request, assign to Licensee any warranties which may be made by the original
manufacturer of such hardware equipment.

  In the event that Licensee makes any changes or modifications to the Licensed
Program, Licensee agrees that such changes and modifications shall be the
property of CA, unless CA shall have given its prior written consent to the
contrary. Furthermore, any such changes or modifications made by Licensee to a
Licensed Program will mean that the foregoing limited warranty of CA with
respect to such Licensed Program shall no longer apply, and CA shall have the
right to charge Licensee for additional support services at CA's then prevailing
service rate, but CA shall have no obligation to provide such services.

WARRANTY AND LIABILITY LIMITATIONS

  EXCEPT AS SET FORTH ABOVE, NO OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED,
INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE, ARE MADE BY CA AND CA MAKES NO WARRANTIES WITH
RESPECT TO ANY HARDWARE EQUIPMENT WHICH CA MAY SUPPLY TOGETHER WITH THE LICENSED
PROGRAM OR FOR THE IMPLEMENTATION THEREOF. IN NO EVENT WILL CA BE LIABLE TO
LICENSEE OR ANY OTHER PARTY FOR ANY LOSS, INCLUDING TIME, MONEY, GOODWILL AND
CONSEQUENTIAL DAMAGES, WHICH MAY ARISE FROM THE USE, OPERATION OR MODIFICATION
OF THE LICENSED PROGRAM.

DISASTER RECOVERY

  In the event that Licensee certifies in writing to CA that it has a bona fide
disaster recovery plan with respect to the computer software programs used in
its operations, Licensee may make one copy of the Licensed Program for archival
purposes and use such archival copy on a CPU other than the Designated CPU or at
an installation site other than that identified on the Order Form, such other
CPU or installation site to be owned or controlled by Licensee. The use of such
archival copy shall be limited (a) for the purpose of conducting limited testing
of the disaster recovery plan's procedures and effectiveness (which testing
shall not exceed one week in any three month period) and (b) during any period
subsequent to the occurrence of an actual disaster during which the Licensee
cannot operate the Licensed Program on the Designated ___________ or at the
installation site identified on the Order Form. Licensee agrees to furnish such
further documentation with respect to its disaster recovery plan and procedures
as CA may request from time to time.

ASSIGNMENT

  Licensee may not assign this Agreement, the use of any Licensed Program or its
rights and obligations under this Agreement without the prior written consent of
CA. CA, however, may assign this Agreement to any third party, provided that
such party assumes the obligations of CA under this Agreement. CA may also
assign its right to payment under this Agreement or grant a security interest in
this Agreement or such payment right to any third party without requiring that
such third party be liable for the obligations of CA under this Agreement.

ESCROW OF SOURCE CODE

  CA has deposited a copy of the source code of the Licensed Program with
Mendelsohn, Kary, Bell & Natoli, 666 Fifth Avenue, New York, NY 10103. Such
source code will be updated with each new release of the Licensed Program which
will also be deposited with the escrow agent. Such copies of the source code
will be held in escrow and in the event of a final adjudication of CA as
bankrupt, Licensee will, upon payment of the duplication cost and other handling
charges of the escrow agent, be entitled to obtain a copy of such source code
from the escrow agent. Licensee will, however, only use such copy of the source
code internally to support the Licensed Program. The escrow agent's only
responsibility will be to use its good faith efforts to cause a copy of the
source code, in the form as delivered by CA, to be delivered to Licensee at the
appropriate time.

TAXES AND DUTIES

  The amounts set forth on any Order Form are exclusive of any tariffs, duties
or taxes imposed or levied by any government or governmental agency including,
without limitation, federal, state and local sales, use, value added and
personal property taxes, and Licensee agrees to pay any such tariffs, duties or
taxes (other than franchise and income taxes for which CA is responsible) upon
presentation of invoices by CA. Any claimed exemption from such tariffs duties
or taxes must be supported by proper documentary evidence delivered to CA.

BREACH AND TERMINATION

  If Licensee breaches any term of this Agreement or any Order Form or fails to
pay when due any valid invoice rendered by CA, or if the Licensee becomes
insolvent or if bankruptcy or receivership proceedings are initiated by or
against Licensee, CA shall have the right to terminate this Agreement
immediately and, in addition to all other rights of CA, all amounts which would
have become due and payable under this Agreement and any Order Form will
immediately become due and payable to CA. Any invoice which is unpaid by
Licensee when due shall be subject to an interest charge of 2% per month or part
thereof plus such late payment charge as CA may reasonably require to cover its
additional costs of administration and collection.

Addendum to License Agreement Between_______________________________ ("Licensee"
And Computer Associates International, Inc. ("CA") For_________________________
__________________________ ("Licensed Program")

  The "Beta Product" is a release of the Licensed Program which is not generally
available for distribution when shipped to the Licensee. The Beta Product is
provided to Licensee for installation in the Licensee's operational environment.
Use of the Beta Product provides the Licensee early operational experience with
the Beta Product and provides CA specific information regarding the Licensee's
experiences with the installation and operation of the Beta Product.

  The referenced License Agreement is hereby supplemented and modified by this
Addendum only as to Licensee's use of the Beta Product. In the event of any
conflict between the License Agreement and this Addendum, the terms and
conditions of this Addendum shall prevail.

  Prior to shipment of the Beta Product by CA, Licensee will establish a
mutually acceptable plan for installation, implementation and reporting. Such
plan may be modified from time to time upon the mutual written agreement of the
parties.

  The period of Beta testing and Beta support (the "Beta Period") shall commence
upon the effective date of this Addendum and shall end upon the earlier of (a)
the date of General Availability ("GA") of the Beta Product, as CA may determine
in its sole discretion, or (b) the date of termination of this Addendum by
either party on not less than 15 days prior written notice to the other.

A.  During the Beta Period, CA will provide the following services:
    --------------------------------------------------------------

1.  Assign a Beta representative to serve as the primary point of contact with
    the Licensee;

2.  Provide planning assistance for installation and operation of the Beta
    Product;

3.  Schedule and ship the Beta Product to the Licensee prior to its General
    Availability;

4.  Provide available publications, education materials and other documentation
    respecting the Beta Product (the "Documentation") to the Licensee: all such
    Documentation, whether or not marked with a trademark notice, copyright
    notice or restrictive legend, such as "CA Confidential," shall be considered
    the confidential and proprietary property of CA and shall be provided to the
    Licensee subject to the provisions of the referenced License Agreement as
    amended hereby; and

5.  Provide support and maintenance, including reasonable remote or, when
    necessary, on-site assistance for the resolution of issues associated with
    the Beta Product.

B.  During the Beta Period, the Licensee will provide the following services:
    ------------------------------------------------------------------------

1.  Assign a Beta representative to serve as the primary point of contact with
    CA;

2.  Staff the Beta project with appropriate personnel to provide planning,
    implementation, operation and reporting with respect to the Beta Product;

3.  Participate in conversion and installation planning sessions with CA;

4.  Use its reasonable efforts to commence operation of the Beta Product
    promptly;

5.  Use the Beta Product and Documentation for testing purposes only and report
    to CA on a weekly basis all errors discovered by Licensee, and not use the
    Beta Product to perform any production activities during the Beta Period
    unless CA shall have otherwise approved in writing;

6.  Document its experiences during the Beta Period and participate in
    conference calls with CA personnel to report on the operational status of
    the Beta Product and to keep CA advised of experiences and any problems
    encountered;

7.  Allow CA personnel reasonable access to the Beta Product during the Beta
    Period for service and observation purposes; and

8.  Furnish to CA at the end of the Beta Period a final written report based on
    the Licensee's experiences, containing the Licensee's evaluation of the
    functions, performance and serviceability of the Beta Period and related
    Documentation.

                                 (over please)

  CA agrees to use its reasonable efforts to correct errors in the Beta Product
and Documentation within a reasonable time. CA does not guarantee or assume
responsibility for any impact of use of the Beta Product on Licensee's existing
production or other environment or on CPU performance. The Documentation may be
in draft form and will, in many cases, be incomplete. Licensee agrees that the
Beta Product and Documentation are being delivered "AS IS" WITHOUT WARRANTIES OF
ANY KIND INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTY OF MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT WILL CA BE LIABLE TO LICENSEE
OR ANY OTHER PERSON FOR DAMAGES, DIRECT OR INDIRECT, OF ANY DESCRIPTION OR
EXPENSES INCURRED BY LICENSEE IN CONNECTION WITH THE USE OF THE BETA PRODUCT.
LICENSEE'S SOLE AND EXCLUSIVE REMEDY SHALL BE TO TERMINATE THE BETA TEST AND
THIS ADDENDUM BY WRITTEN NOTICE TO CA.

  CA cannot guarantee that the generally available release of the Licensed
Program will be identical to the Beta Product and therefore a re-installation of
the generally available released version may be required. If, at the conclusion
of the Beta Period, the software and Documentation are not generally released by
CA to its clients, Licensee shall have the right to receive from CA without any
additional charge, a perpetual license to use the Beta Product and Documentation
for its internal use only, provided that CA shall have no responsibility or
liability to Licensee for any further support or maintenance of the Beta Product
or Documentation.

  Licensee agrees that it will not disclose the Beta Product, the Documentation,
or any information gained from its use of the Beta Product and Documentation to
any third party without the prior written consent of CA. CA agrees to maintain
the confidentiality of any live customer data utilized at any time during the
Beta Period which comes into CA's possession. With reasonable notification,
Licensee agrees to be a positive reference for CA during and after the Beta
Period.

  The Licensee agrees that the reports prepared by the Licensee and delivered to
CA may be used by CA for all business purposes without any further consent or
accounting in the development, manufacture, marketing and maintenance of the
Beta Product and other CA products and services, including reproduction and
preparation of derivative works based upon such reports, as well as distribution
of such derivative works.

  Nothing contained herein shall be construed as conferring upon Licensee or CA
any right to use in advertising, publicity or other marketing activities, any
name, trade name, trademark, or other designation of the other party or to refer
to the existence hereof in any promotional activity without the express written
consent of such other party.

  This Addendum shall not be construed to prohibit either CA or Licensee from
entering into a similar agreement with any other party nor from independently
developing, offering, selling or marketing materials, products or services which
are similar to the materials, products or services provided hereunder.

  If the Beta Product is a new release of an already Licensed Program, future
usage and maintenance fees shall be payable in accordance with the terms and
conditions of the License Agreement for the already Licensed Program.

  If the Beta Product is being newly licensed by the client, then the initial
license fee shall be payable in accordance with the License Agreement and Order
Form with subsequent usage and maintenance fees payable on each anniversary of
the date on which the Licensee shall have received a version of the Licensed
Program in General Availability status or received CA's notification that the
Beta Product has reached General Availability status.

upgraded or expanded at any time during the term of the Order upon prior written
notice to CA. The expiration date of the term of the Order or the then current 
usage and maintenance period for the existing license shall not change, and it 
shall apply to the upgraded or expanded license. All applicable upgrade fees 
and adjustments to the license fees and applicable UMFs for an upgraded or 
expanded license shall be determined in accordance with CA's policy and prices 
prevailing at the time of the upgrade.

ADDITIONAL CPU(s)

        Additional CPU(s) at the same installation site may be licensed to use 
the Licensed Program. In order to add one or more CPU(s), one copy of the 
Licensed Program at the installation site must either have an existing license
to run on a CPU in the highest CPU group at the installation site, or be
upgraded to a CPU in that highest CPU group in accordance with the "Upgrade"
policy of CA. The license for additional CPU(s) may be an Option G1, G2, A0 or
A8 only if the license for the Licensed Program in the highest CPU group shall
be an Option G1, G2, A0 or A8. Provided that the first CPU has been upgraded to
or is licensed for use in the highest CPU group at the installation site, the
license fee, and any subsequent UMF, for each additional CPU at the same
installation site shall be the then prevailing license fee or UMF, as the case
may be, applicable to the additional CPU. In all cases, such additional CPU
license fee or UMF shall only apply during such time as the Order and UMF for
the Licensed Program in the highest CPU group shall be current and in effect.

CONVERSION CREDIT

        A "Rightsizing Credit" may be available when Licensee decides to change 
the hardware platform or operating system for which the Licensed Program was 
originally licensed to another platform or different operating system such as a 
workstation or personal computer. In qualifying instances, the Rightsizing 
Credit will be equal to the license fee actually paid for the original Licensed
Program on the original hardware platform or operating system (less a usage
charge of 2% per month) up to a maximum credit of one-half of the fee otherwise
applicable. (No cash refunds will be payable under any circumstance.)
Rightsizing Credit are available only in respect to Licensed Programs under
active maintenance status and to Licensees that maintain enrollment in CA's
Total Client Care Program.

CLIENT SERVICES

        New releases or Licensed Program upgrades are not included as a part of
annual maintenance and support services for workstation and micro computer 
software. All of the terms and conditions contained in the License Agreement 
referred to in this Order Form shall apply to the Services ordered hereunder.
All programs, documentation, reports, techniques, designs and other materials
prepared or created by CA shall remain the property of CA and shall not
constitute work made for hire under the Copyright Act. The fees set forth in
this Order Form for Services, as more fully set forth in the attached
description(s), do not include out-of-pocket expenses (such as transportation,
lodging, meal per diem, and other expenses) incurred by CA while providing the
Services ordered, which expenses will be charged to the Licensee from time to
time or upon completion of the ordered Services. If performance of the Services
is delayed due to Licensee's failure to provide required computer access or
personnel or similar reasons, Licensee shall pay CA's then prevailing daily
charge, plus reimbursement of all such out-of-pocket expenses, for each
additional day for each person assigned by CA to provide the Services.

REFERENCED LICENSE AGREEMENT

as the case may be, referenced by this Order Form shall apply to this Order

may be, shall contradict any provision of this Order Form, the provisions of 
this Order Form shall apply with respect to the Licensed Program(s) described 
herein. If the License Agreement referred to in this Order Form currently
provides for a license of Licensed Program(s) for use on an "installation or
site basis," then the same shall be amended for purposes of the Licensed
Program(s) covered by this Order Form, to a license for use on a "per CPU"
basis.

                             The Warrants will be issued in two certificates for
                             47,794 shares each (one certificate in Lender's

                             warranties of the Borrower in the Loan.

monthly to an annual basis. Subject to the terms and conditions of this
Agreement, amounts borrowed pursuant to this Section 2.1 may be repaid and
reborrowed at any time prior to the Revolving Maturity Date.

     Whenever Borrower desires an Advance, Borrower will notify Bank by

based upon instructions received from a Responsible Officer, or without

Obligations which have become due and remain unpaid.  Bank shall be entitled to
rely on any telephonic notice given by a person who Bank reasonably believes to
be a Responsible Officer, and Borrower shall indemnify and hold Bank harmless
for any damages or loss suffered by Bank as a result of such reliance.  Bank
will credit the amount of Advances made under this Section 2.1 to Borrower's
deposit account.

credit shall have an expiry date no later than the Maturity Date; provided that

term of the Revolving Facility is not extended by Bank. All such letters of
credit shall be, in form and substance, acceptable to Bank in its sole
discretion and shall be subject to the terms and conditions of Bank's form of
application and letter of credit agreement. All amounts actually paid by Bank in
respect of a letter of credit shall,

when paid, constitute an Advance under this Agreement.

                      (b)  The Obligation of Borrower to immediately reimburse
Bank for drawings made under Letters of Credit shall be absolute, unconditional
and irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement and such Letters of Credit, under all circumstances whatsoever.

expense or liability, including, without limitation, reasonable attorneys' fees,

                      (a)  Borrower may request that Bank issue a letter of
credit payable in a currency other than United States Dollars. If a demand for
payment is made under any such letter of credit, Bank shall treat such demand as
an advance to Borrower of the equivalent of the amount thereof (plus cable
charges) in United States currency at the then prevailing rate of exchange in
San Francisco, California, for sales of that other currency for cable transfer
to the country of which it is the currency .

                      (b)  Upon the issuance of any letter of credit payable in
a currency other than United States Dollars, Bank shall create a reserve under
the Committed Line for letters of credit against fluctuations in currency
exchange rates, in an amount equal to twenty percent (20%) of the face amount of
such letter of credit. The amount of such reserve may be amended by Bank from
time to time to account for fluctuations in the exchange rate. The availability
of funds under the Committed Line shall be reduced by the amount of such reserve
for so long as such letter of credit remains outstanding.

               2.1.4  Equipment Advances.

shall be in substantially the form of Exhibit B.  The notice shall be signed by 
                                      --------- 
a Responsible Officer and include a copy of the invoice for the Equipment to be
financed.

          2.2  Overadvances.  If, at any time or for any reason, the amount of
               ------------
Obligations owed by Borrower to Bank pursuant to Section 2.1 of this Agreement
is greater than the lesser of (i) the Committed Line or (ii) the Borrowing Base,
Borrower shall immediately pay to Bank, in cash, the amount of such excess.

          2.3  Interest Rates, Payments, and Calculations.  
               ------------------------------------------ 

               (a)  Interest Rate.  Except as set forth in Section 2.3(b), any
                    -------------
Advances shall bear interest, on the average Daily Balance, at a rate equal to
one (1.0) percentage points above the Prime Rate. Except as set forth in Section
2.3(b), any Equipment Advances shall bear interest on the average Daily Balance,
at a rate equal to two and one-half (2.5) percentage points above the Prime
Rate.

               (b)  Default Rate.  All Obligations shall bear interest, from 
                    ------------        
and after the occurrence of an Event of Default, at a rate equal to five (5)
percentage points above the interest rate applicable immediately prior to the
occurrence of the Event of Default.

               (c)  Payments.  Interest hereunder shall be due and payable on 
                    --------                                                  
the thirteenth calendar day of each month during the term hereof. Bank shall, at
its option, charge such interest, all Bank Expenses, and all Periodic Payments
against any of Borrower's deposit accounts or against the Committed Line, in
which case those amounts shall thereafter accrue interest at the rate then
applicable hereunder. Any interest not paid when due shall be compounded by
becoming a part of the Obligations, and such interest shall thereafter accrue
interest at the rate then applicable hereunder.

               (d)  Computation.  In the event the Prime Rate is changed from 
                    -----------     
time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased effective as of 12:01 a.m. on the day the Prime Rate is
changed, by an amount equal to such change in the Prime Rate. All interest
chargeable under the Loan Documents shall be computed on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed.

          2.4  Crediting Payments.  Prior to the occurrence of an Event of
               ------------------
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment shall be immediately applied to
conditionally reduce Obligations, but shall not be considered a payment on
account unless such payment is of immediately available federal funds or unless
and until such check or other item of payment is honored when presented for
payment. Notwithstanding anything to the contrary contained herein, any wire
transfer or payment received by Bank after 12:00 noon California time shall be
deemed to have been received by Bank as of the opening of business on the
immediately following Business Day. Whenever any payment to Bank under the Loan
Documents would otherwise be due (except by reason of acceleration) on a date
that is not a Business Day, such payment shall instead be due on the next
Business Day, and additional fees or interest, as the case may be, shall accrue
and be payable for the period of such extension.

          2.5  Fees.  Borrower shall pay to Bank the following:
               ----
     
               (a)  Facility Fee.  A Facility Fee equal to Two Thousand Five

Hundred Dollars ($2,500), which fee shall be due upon the making of the first
Advance (which shall not include issuing the Landlord Letter of Credit), plus
Two Thousand Five Hundred Dollars ($2,500), which shall be payable when the
aggregate Advances (excluding the Landlord Letter of Credit) exceed Five Hundred
Thousand Dollars ($500,000), plus Four Thousand Two Hundred Fifty Dollars

nonrefundable;

               (b)  Financial Examination and Appraisal Fees.  Bank's customary 
                    ---------------------------------------- 
fees and out-of-pocket expenses for Bank's audits of Borrower's Accounts (not to
exceed $400 per audit), and for each appraisal of Collateral and financial
analysis and examination of Borrower performed from time to time by Bank or its
agents 
<PAGE>
 
conducted in compliance with Section 6.3 herein;

               (c)  Bank Expenses.  Upon the date hereof, all Bank Expenses 
                    -------------    
incurred through the Closing Date, including reasonable attorneys' fees and
expenses (not to exceed $1,500), and, after the date hereof, all Bank Expenses,
including reasonable attorneys' fees and expenses, as and when they become due.

          2.6  Additional Costs.  In case any change in any law, regulation, 
               ----------------
treaty or official directive or the interpretation or application thereof by any
court or any governmental authority charged with the administration thereof or
the compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law), in each case
after the date of this Agreement:

               (a)  subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for taxes
on the overall net income of Bank imposed by the United States of America or any
political subdivision thereof);

               (b)  imposes, modifies or deems applicable any deposit insurance,
reserve, special deposit or similar requirement against assets held by, or
deposits in or for the account of, or loans by, Bank; or

               (c)  imposes upon Bank any other condition with respect to its
performance under this Agreement,

and the result of any of the foregoing is to increase the cost to Bank, reduce
the income receivable by Bank or impose any expense upon Bank with respect to
any loans, Bank shall notify Borrower thereof.  Borrower agrees to pay to Bank
the amount of such increase in cost, reduction in income or additional expense
as and when such cost, reduction or expense is incurred or determined, upon
presentation by Bank of a statement of the amount and setting forth Bank's
calculation thereof, all in reasonable detail, which statement shall be deemed
true and correct absent manifest error; provided, however, that the Borrower
shall not be liable for any such amount attributable to any period prior to the
date one hundred and eighty (180) days prior to the date of such certificate.
Bank agrees that it will allocate all such increased costs among its customers
similarly affected in good faith and in a manner consistent with Bank's
customary practice.

          2.7  Term.  This Agreement shall become effective on the Closing Date
               ----
and, subject to Section 12.7, shall continue in full force and effect for a term
ending on the Maturity Date. Notwithstanding the foregoing, Bank shall have the
right to terminate its obligation to make Advances under this Agreement
immediately and without notice upon the occurrence and during the continuance of
an Event of Default. Notwithstanding termination, Bank's Lien on the Collateral
shall remain in effect for so long as any Obligations are outstanding.

     4.   CREATION OF SECURITY INTEREST
          -----------------------------
 
          4.1  Grant of Security Interest.  Borrower grants and pledges to Bank
               --------------------------
a continuing security interest in all presently existing and hereafter acquired
or arising Collateral in order to secure prompt repayment of any and all
Obligations and in order to secure prompt performance by Borrower of each of its
covenants and duties under the Loan Documents. Except as set forth in the
Schedule, such security interest constitutes a valid, first priority security
interest in the presently existing Collateral, and will constitute a valid,
first priority security interest in Collateral acquired after the date hereof.

          4.2  Delivery of Additional Documentation Required.  Borrower shall 
               ---------------------------------------------

in good standing in, any state in which the conduct of its business or its
ownership of property requires that it be so qualified.

          5.2  Due Authorization; No Conflict.  The execution, delivery, and
               ------------------------------
performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor will
they constitute an event of default under any material agreement to which
Borrower is a party or by which Borrower is bound. Borrower is not in default
under any agreement to which it is a party or by which it is bound, which
default could
<PAGE>
 
have a Material Adverse Effect.

          5.3  No Prior Encumbrances.  Borrower has good and indefeasible title
               ---------------------
to the Collateral, free and clear of Liens, except for Permitted Liens.

any account debtor that is included in any Borrowing Base Certificate as an
Eligible Account.

               ----------
actions or proceedings pending by or against Borrower or any Subsidiary before

Bank's security interest in the Collateral. Borrower does not have knowledge of
any such pending or threatened actions or proceedings.

          5.8  No Material Adverse Change in Financial Statements.  All

maintain, and shall cause each of its Subsidiaries to maintain, to the extent

to have a Material Adverse Effect.

     8.   EVENTS OF DEFAULT
          -----------------

          Any one or more of the following events shall constitute an Event of
Default by Borrower under this Agreement:

          8.1  Payment Default.  If Borrower fails to pay the principal of, or
               ---------------
any interest on, any Advances when due and payable; or fails to pay any portion
of any other Obligations not constituting such principal or interest, including
without limitation Bank Expenses, within thirty (30) days of receipt by Borrower

contained in Article 7 of this Agreement, or fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or agreement
contained in this Agreement, in any of the Loan Documents, or in any other
present or future agreement between Borrower and Bank and as to any default
under such other term, provision, condition, covenant or agreement that can be
cured, has failed to cure such default within ten (10) days after Borrower
receives notice thereof or any officer of Borrower becomes aware thereof;
provided, however, that if the default cannot by its nature be cured within the
ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within a
reasonable time, then Borrower shall have an additional reasonable period (which
shall not in any case exceed thirty (30) days) to attempt to cure such default,
and within such reasonable time period the failure to have cured such default
shall not be deemed an Event of Default (provided that no Advances will be
required to be made during such cure period);

          8.3  Material Adverse Change.  If there occurs a material adverse
               -----------------------
change in Borrower's business or financial condition, or if there is a material
impairment of the prospect of repayment of any portion of the Obligations or a
material impairment of the value or priority of Bank's security interests in the
Collateral;

          8.4  Attachment.  If any material portion of Borrower's assets is

has not been removed, discharged or rescinded within ten (10) days, or if
Borrower is enjoined, restrained, or in any way prevented by court order from
continuing to conduct all or any material part of its business affairs, or if a
judgment or other claim becomes a lien or encumbrance upon any material portion
of Borrower's assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of Borrower's assets by the United States Government,
or any department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within ten (10) days
after Borrower receives notice thereof, provided that none of the foregoing
shall constitute an Event of Default where such action or event is stayed or an
adequate bond has been posted pending a good faith contest by Borrower (provided
that no Advances will be required to be made during such cure period);

          8.5  Insolvency.  If Borrower becomes insolvent, or if an Insolvency
               ----------
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced
against Borrower and is not dismissed or stayed within ten (10) days (provided
that no Advances will be made prior to the dismissal of such Insolvency
Proceeding);

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

in an amount, individually or in the aggregate, of at least Fifty Thousand
Dollars ($50,000) shall be rendered against Borrower and shall remain
unsatisfied and unstayed for a period of ten (10) days (provided that no
Advances will be made prior to the satisfaction or stay of such judgment); or

          8.9  Misrepresentations.  If any material misrepresentation or
               ------------------
material misstatement exists now or hereafter in any warranty or representation
set forth herein or in any certificate delivered to Bank by any Responsible
Officer pursuant to this Agreement or to induce Bank to enter into this

     9.   BANK'S RIGHTS AND REMEDIES
          --------------------------

          9.1  Rights and Remedies.  Upon the occurrence and during the
               -------------------
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

               (a)  Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5 all Obligations shall become immediately due and payable without any
action by Bank);

               (b)  Cease advancing money or extending credit to or for the
benefit of Borrower under this Agreement or under any other agreement between
Borrower and Bank;

               (c)  Demand that Borrower (i) deposit cash with Bank in an amount
equal to the amount of any Letters of Credit remaining undrawn, as collateral
security for the repayment of any future drawings under such Letters of Credit,
and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in
advance all Letters of Credit fees scheduled to be paid or payable over the
remaining term of the Letters of Credit;

               (d)  Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;
<PAGE>
 
               (e)  Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to protect
its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Bank so requires, and to make the Collateral available to Bank as
Bank may designate. Borrower authorizes Bank to enter the premises where the
Collateral is located, to take and maintain possession of the Collateral, or any
part of it, and to pay, purchase, contest, or compromise any encumbrance,
charge, or lien which in Bank's determination appears to be prior or superior to
its security interest and to pay all expenses incurred in connection therewith.
With respect to any of Borrower's owned premises, Borrower hereby grants Bank a
license to enter into possession of such premises and to occupy the same,
without charge, in order to exercise any of Bank's rights or remedies provided
herein, at law, in equity, or otherwise ;

               (f)  Without notice to Borrower set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank, or
(ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

               (g)   Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

               (h)  Sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

               (i)  Bank may credit bid and purchase at any public sale; and

               (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

          9.2  Power of Attorney.  Effective only upon the occurrence and during
               -----------------
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated, provided that
such appointments triggered by an Event of Default shall be irrevocable until
the Event of Default is cured, to the extent such Event of Default may be cured.

          9.3  Accounts Collection.  At any time from the date of this
               -------------------
Agreement, Bank may notify any Person owing funds to Borrower of Bank's security
interest in such funds and verify the amount of such Account. Borrower shall
collect all amounts owing to Borrower for Bank, receive in trust all payments as
Bank's trustee, and immediately deliver such payments to Bank in their original
form as received from the account debtor, with proper endorsements for deposit.

          9.4  Bank Expenses.  If Borrower fails to pay any amounts or furnish
               -------------
any required proof of 
<PAGE>
 
payment due to third persons or entities, as required under the terms of this
Agreement, then Bank may do any or all of the following: (a) make payment of the
same or any part thereof; (b) set up such reserves under the Revolving Facility
as Bank deems necessary to protect Bank from the exposure created by such
failure; or (c) obtain and maintain insurance policies of the type discussed in
Section 6.6 of this Agreement, and take any action with respect to such policies
as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute
Bank Expenses, shall be immediately due and payable, and shall bear interest at
the then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by Bank
to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

          9.5  Bank's Liability for Collateral.  So long as Bank complies with
               -------------------------------
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

          9.6  Remedies Cumulative.  Bank's rights and remedies under this
               -------------------
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

          9.7  Demand; Protest.  Borrower waives demand, protest, notice of
               ---------------
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

                        AGREEMENT TO PROVIDE INSURANCE


GRANTOR:  EXODUS COMMUNICATIONS, INC.              BANK:   Silicon Valley Bank

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

     INSURANCE REQUIREMENTS.  EXODUS COMMUNICATIONS, INC. ("Grantor")
understands that insurance coverage is required in connection with the extending
of a loan or the providing of other financial accommodations to Grantor by Bank.
These requirements are set forth in the Loan Documents.  The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

          Collateral:     All Inventory, Equipment and Fixtures.
          Type:           All risks, including fire, theft and liability.
          Amount:         Full insurable value.
          Basis:          Replacement value.
          Endorsements:   Loss payable clause to Bank with stipulation that
                          coverage will not be cancelled or diminished without a
                          minimum of twenty (20) days' prior written notice to
                          Bank.

     INSURANCE COMPANY.  Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to Bank.  Grantor understands
that credit may not be denied solely because insurance was not purchased through
Bank.

     FAILURE TO PROVIDE INSURANCE.  Grantor agrees to deliver to Bank, on or
before closing, evidence of the required insurance as provided above, with an
effective date of June 14, 1996, or earlier.  Grantor acknowledges and agrees
that if Grantor fails to provide any required insurance or fails to continue
such insurance in force, Bank may do so at Grantor's expense as provided in the
Loan and Security Agreement.  The cost of such insurance, at the option of Bank,
shall be payable on demand or shall be added to the indebtedness as provided in
the security document.  GRANTOR ACKNOWLEDGES THAT IF BANK SO PURCHASES ANY SUCH
INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION AGAINST PHYSICAL DAMAGE
TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN; HOWEVER, GRANTOR'S EQUITY IN
THE COLLATERAL MAY NOT BE INSURED.  IN ADDITION, THE INSURANCE MAY NOT PROVIDE

3.   DESCRIPTION OF CHANGE IN TERMS.
     ------------------------------ 

     A.   Modification(s) to Loan Agreement.
          ---------------------------------

          1.   The term "Revolving Maturity Date" shall mean July 13, 1997.

          2.   Section 6.3 entitled "Financial Statements, Reports,
               Certificates" is hereby amended to allow Borrower to deliver to

     B.   Waiver of Covenant Defaults.
          ----------------------------

               Bank hereby waives Borrower's existing defaults under the Loan
               Agreement by virtue of Borrower's failure to comply with the
               Quick Ratio, Debt-Net Worth Ratio and Private Placement covenants
               as of the month ended May 31, 1997. Bank's waiver of Borrower's
               compliance of these covenants shall apply only to the foregoing
               periods. Accordingly, for the month end in which the Borrower
               receives the Private Placement Borrower shall be in compliance
               with the foregoing covenants, as amended herein.

               Bank's agreement to waive the above-described defaults (1) in no
               way shall be deemed an agreement by the Bank to waive Borrower's
               compliance with the above-described covenants as of all other
               dates and (2) shall not limit or impair the Bank's right to
               demand strict performance of these covenants as of all other
               dates and (3) shall not limit or impair the Bank's right to
               demand strict performance of all other covenants as of any date.

4.   CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
     ------------------
necessary to reflect the changes described above.

5.   NO DEFENSES OF BORROWER. Borrower (and each guarantor and pledgor signing
     -----------------------
below) agrees that it has no defenses against the obligations to pay any amounts
under the Indebtedness.

6.   CONTINUING VALIDITY. Borrower (and each guarantor and pledgor signing 
     -------------------                                                        
below) understands and agrees that in modifying the existing Indebtedness, Bank
is relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect. Banks agreement to modifications
to the existing Indebtedness pursuant to this Loan Modification Agreement in no
way shall obligate Bank to make any future modifications to the Indebtedness.
Nothing in this Loan Modification Agreement shall constitute a satisfaction of
the Indebtedness. It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly released by Bank in writing. No maker, endorser, or guarantor will be
released by virtue of this Loan Modification Agreement. The terms of this
paragraph apply not only to this Loan Modification Agreement, but also to all
subsequent loan modification agreements.

     This Loan Modification Agreement is executed as of the date first written

                          LOAN AND SECURITY AGREEMENT
                          ---------------------------

     This Amendment to Loan and Security Agreement is entered into as of
December 8, 1997 by and between SILICON VALLEY BANK ("Bank") and EXODUS
COMMUNICATIONS, INC. ("Borrower").

                                   RECITALS
                                   --------

     Borrower and Bank are parties to that certain Loan and Security Agreement
dated as of June 14, 1996, as amended (the "Agreement"). The parties desire to
amend the Agreement in accordance with the terms of this Amendment.

     NOW, THEREFORE, the parties agree as follows:

     1.   The following definitions in Section 1.1 are amended to read as
follows:

          "Committed Line" means Five Million Dollars ($5,000,000).

          "Current Liabilities" means, as of any applicable date, all amounts
that should, in accordance with GAAP, be included as current liabilities on the
consolidated balance sheet of Borrower and its Subsidiaries, as at such date,
plus, to the extent not already included therein, all outstanding Advances made
under this Agreement and the current month's scheduled principal payments of
long term debt.

          "Pre-billed Revenue" means the revenue received by Borrower from
     account debtors on account of invoices delivered for services to be
     rendered in the ordinary course of Borrower's business during the period
     following receipt of such invoices, which invoices are to be paid by
     customers in the ordinary course of business within thirty (30) days after
     receipt of such invoices.

          "Quick Assets" means, at any date as of which the amount thereof shall
     be determined, the consolidated unrestricted cash, cash-equivalents,
     accounts receivable, current month's Pre-billed Revenue and investments
     with maturities not to exceed 90 days, of Borrower determined in accordance
     with GAAP.

          "Revolving Maturity Date" means December 7, 1998.

     2.   Section 2.1 is amended to read as follows:

          2.1  Advances. Subject to and upon the terms and conditions of this
               --------
     Agreement, Bank agrees to make Advances to Borrower in an aggregate amount
     not to exceed the lesser of the Committed Line or the Borrowing Base minus,
     in each case, the face amount of outstanding Letters of Credit (including
     drawn but unreimbursed Letters of Credit). For purposes of this Agreement,
     "Borrowing Base" shall mean an amount equal to eighty (80%) of Borrower's
     aggregate Pre-billed Revenue for the month immediately preceding the month
     in which an Advance is requested times four (4); provided that no Advances
                                                      --------
     may be outstanding after any month in which Borrower has suffered a decline
     in Pre-billed Revenue from the immediately previous month. Subject to the
     terms and conditions of this Agreement, amounts borrowed pursuant to this
     Section 2.1 may be repaid and reborrowed at any time prior to the Revolving
     Maturity Date.

          Whenever Borrower desires an Advance, Borrower will notify Bank by
     facsimile transmission or telephone no later than 3:00 p.m. California
     time, on the Business Day that the Advance is to be made. Each such
     notification shall be promptly confirmed by a Payment/Advance Form in
     substantially the form of Exhibit B hereto. Bank is authorized to make
                               --------- 
     Advances under this Agreement, based upon instructions received from a
     Responsible Officer, or without instructions if in Bank's discretion such
     Advances are necessary to meet Obligations which have become due and remain
     unpaid. Bank shall be entitled to rely on any telephonic notice given by a
     person who Bank reasonably believes to be a Responsible Officer, and

                                       1
<PAGE>
 
     Borrower shall indemnify and hold Bank harmless for any damages or loss
     suffered by Bank as a result of such reliance. Bank will credit the amount
     of Advances made under this Section 2.1 to Borrower's deposit account.

          The Revolving Facility shall terminate on the Revolving Maturity Date
     at which time all Advances under this Section 2.1 shall be immediately due
     and payable.

     3.   The reference in Section 2.1.1 to "Three Hundred Thousand Dollars

     4.   Section 2.3(a) is amended to read as follows:

          (a)  Interest Rate. Except as set forth in Section 2.3(b), any
               -------------
Advances under Section 2.1 shall bear interest, on the average Daily Balance, at
a rate equal to one percent (1.00%) above the Prime Rate and, after the Borrower
closes its initial public offering, at a rate equal to the Prime Rate.

     5.   Sections 6.8, 6.9, and 6.10 are amended to read as follows:

          6.8  Quick Ratio.  Borrower shall maintain, as of the last day of each
               -----------                                                      
calendar month, a ratio of Quick Assets to Current Liabilities of at least 1.00
to 1.00, provided that such ratio for the month ending December 31, 1997 shall
be at least 0.75 to 1.00.  Beginning February 28, 1998, Borrower shall maintain,
as of the last day of each month, a ratio of Quick Assets to Current Liabilities
of at least 1.50 to 1.0.

          6.9  Profitability. Borrower shall not suffer a loss in excess of
               -------------

          6.10 Monthly Decline in Pre-billed Revenue. Borrower shall not suffer
               ------------------------------------- 
any decline in the Pre-billed Revenue for any month from the immediately
preceding month.

     6.   The Borrowing Base Certificate and Compliance Certificate to be
delivered after the date of this Amendment shall be in substantially the form of
Exhibit C and Exhibit D hereto. The Borrowing Base Certificate and aged listings
- ---------     ---------
of Accounts Receivable and Accounts Payable shall be due only for months in
which any Advances are outstanding.

     7.   Unless otherwise defined, all capitalized terms in this Amendment
shall be as defined in the Agreement. Except as amended, the Agreement remains
in full force and effect.

     8.   Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

     9.   This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one instrument.

     10.  As a condition to the effectiveness of this Amendment, Borrower shall
pay a Facility Fee in an amount equal to Twenty Five Thousand Dollars ($25,000),
payable upon the date hereof, plus all Bank Expenses incurred in connection with
the preparation of this Amendment, and shall deliver to Bank a warrant to
purchase stock in a form reasonably acceptable to Bank.

first date above written.

     This Loan Modification Agreement is entered into as of December 30, 1997,
by and between Exodus Communications, Inc. ("Borrower") whose address is 2650
San Tomas Expressway, Santa Clara, CA 95051, and Silicon Valley Bank ("Bank")
whose address is 3003 Tasman Drive, Santa Clara, CA 95054.

1.   DESCRIPTION OF EXISTING INDEBTEDNESS:  Among other indebtedness which may
     ------------------------------------                                     
be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among
other documents, a Loan and Security Agreement, dated June 14, 1996, together
with all schedules thereto (the "Loan Agreement"), as may be amended from time
to time.  The Loan Agreement provided for, among other things, a Committed Line
in the original principal amount of One Million Dollars ($1,000,000) (the
"Revolving Facility"). The Revolving Facility has been modified pursuant to,
among other documents, an Amendment to Loan and Security Agreement dated
December 8, 1997, pursuant to, among other things the Committed Line was
increased to Five Million Dollars ($5,000,000).  Defined terms used but not
otherwise defined herein shall have the same meanings as in the Loan Agreement.

Hereinafter, all indebtedness owing by Borrower to Bank shall be referred to as
the "Indebtedness".

2.   DESCRIPTION OF COLLATERAL AND GUARANTIES.  Repayment of the Indebtedness is
     ----------------------------------------                                   
secured by the Collateral as defined in the Loan Agreement, and a Collateral
Assignment, Patent Mortgage and Security Agreement dated June 13, 1996.

Hereinafter, the above-described security documents and guaranties, together
with all other documents securing repayment of the Indebtedness shall be
referred to as the "Security Documents".  Hereinafter, the Security Documents,
together with all other documents evidencing or securing the Indebtedness shall
be referred to as the "Existing Loan Documents".

3.   DESCRIPTION OF CHANGE IN TERMS.
     ------------------------------ 

     A.   Waiver of Covenant Defaults.
          --------------------------- 

          Bank hereby waives Borrower's existing defaults under the Loan
          Agreement by virtue of Borrower's failure to comply with (i) the Quick
          Ratio and Debt-Net Worth Ratio covenants as of the month ended
          November 30, 1997 and (ii) the Profitability covenant as of the fiscal
          quarter ending December 31, 1997.  Bank's waiver of Borrower's
          compliance of these covenants shall apply only to the foregoing
          periods.  Accordingly, Borrower shall be in compliance with (a) the
          Quick Ratio covenant as of month ending December 31, 1997 and (b) the
          Profitability covenant as of the fiscal quarter ending March 31, 1998.
          Pursuant to an Amendment to Loan and Security Agreement dated December
          8, 1997, the Debt-Net Worth Ratio covenant is no longer required.

          Bank's agreement to waive the above-described defaults (1) in no way
          shall be deemed an agreement by the Bank to waive Borrower's
          compliance with the above-described covenants as of all other dates
          and (2) shall not limit or impair the Bank's right to demand strict
          performance of these covenants as of all other dates and (3) shall not
          limit or impair the Bank's right to demand strict performance of all
          other covenants as of any date.

4.   CONSISTENT CHANGES.  The Existing Loan Documents are hereby amended
     ------------------                                                 
wherever necessary to reflect the changes described above.

5.   NO DEFENSES OF BORROWER.  Borrower (and each guarantor and pledgor signing
     -----------------------                                                   
below) agrees that it has no defenses against the obligations to pay any amounts
under the Indebtedness.

6.   CONTINUING VALIDITY.  Borrower (and each guarantor and pledgor signing
     -------------------                                                   
below) understands and agrees that in modifying the existing Indebtedness, Bank
is relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents.  Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect.  Bank's agreement to
modifications to the existing Indebtedness pursuant to this Loan Modification
Agreement in no way shall obligate Bank to make any future modifications to the
Indebtedness.  Nothing in this Loan Modification Agreement shall constitute a
satisfaction of the Indebtedness.  It is the intention of Bank and Borrower to
retain as liable parties all makers and endorsers of Existing Loan Documents,
unless the party is expressly released by Bank in writing.  No maker, endorser,
or guarantor will be released by virtue of this Loan Modification Agreement.
The terms of this paragraph apply not only to this Loan Modification Agreement,
but also to all subsequent loan modification agreements.

     This Loan Modification Agreement is executed as of the date first written
above.

Agreement and relying upon the representations and warranties herein set forth
as and when made or deemed to be made, each Lender agrees to lend to Borrower
such Lender's pro rata share of the Credit Amount (based upon the respective
Commitment of each Lender).  The Loan may not be prepaid except in accordance
with Section 2.02(e).

     (b)   Loan Interest Rate.  Borrower shall pay interest on the unpaid
           ------------------

full, at a per annum rate of interest equal to the Loan Rate determined in
accordance with the definition of Loan Rate.  The Loan Rate applicable to the
Loan shall not be subject to change in the absence of manifest error.  All
computations of interest on the Loan shall be based on a year of twelve 30 day
months.  If Borrower pays interest on the Loan which is determined to be in

payment representing an amount in excess of the then legal maximum rate shall be

forth in the first two sentences of this Section 2.01(c), but the principal of
the Loan shall be payable in twelve equal installments plus accrued interest on
the outstanding principal balance on each Payment Date, commencing on January 4,
1999; provided, that only if Borrower and both Lenders agree, Borrower may
prepay all of the principal and accrued interest on January 4, 1999.

     (d)   Loan Fee.  On January 4, 1999, in addition to any outstanding

Lender's pro rata share of the unpaid principal amount of and interest on the
Loan shall be evidenced by a Note issued to each Lender and each Lender is
authorized to endorse on a grid annexed to its Note appropriate notations
regarding payments made on the Note; provided, however, that the failure to
                                     --------  -------

Borrower.  Notwithstanding anything stated herein to the contrary, neither
Lender shall have any obligation to advance funds on behalf of the other Lender.

right of payment, in an aggregate principal amount of not less than $15,000,000,
Borrower shall give Lenders written notice thereof and Lenders shall have the
option to cause Borrower to prepay to the Lenders at the closing of the new debt
financing the outstanding principal amount of the Loan, at a prepayment price
equal to the principal amount of the Loan outstanding, plus interest accrued
thereon through and including the date of such prepayment, plus a premium equal
to the Make-Whole Premium. Lenders shall give written notice to Borrower within
ten (10) Business Days of receipt of notice from Borrower of whether Lenders
will require such prepayment. If Lenders do not require such prepayment but are
unwilling to amend this document to permit the incurrence of the Indebtedness in
connection with the new debt financing on the terms and conditions proposed,
Borrower shall have the right to prepay all and not less than all of the
principal amount of the Loan at the prepayment price specified above.

Borrower under this Agreement or the other Operative Documents (including
principal or interest payable on the Loan, any fees or other amounts) remain
unpaid after such amounts are due, or (ii) an Event of Default has occurred and

properties is or has been affected by any fire, explosion, accident, strike,
lockout or other labor dispute, drought, storm, hail, earthquake, embargo, act
of God or other casualty that could reasonably be expected to have a material
adverse effect on the financial condition, business or operations of Borrower.
There are no disputes presently subject to grievance procedure, arbitration or
litigation under any of the collective bargaining agreements, employment
contracts or employee welfare or incentive plans to which Borrower is a party,
and there are no strikes, lockouts, work stoppages or slowdowns, or, to the best
knowledge of Borrower, jurisdictional disputes or organizing activity occurring
or threatened which could reasonably be expected to have a material adverse
effect on the financial condition, business or operations of Borrower.

     (k)   No Material Adverse Effect . No event has occurred and no condition
           --------------------------  
exists which could reasonably be expected to have a material adverse effect on
the financial condition, business or operations of Borrower since December 31,
1996.

     (l)   Accuracy of Information Furnished. None of the Operative Documents
           ---------------------------------
and none of the other certificates, statements or information furnished to
Lenders by or on behalf of Borrower in connection with the Operative Documents
or the transactions contemplated thereby contains or will contain any untrue
statement of a material fact or omits or will omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. Lenders recognize that all financial
projections furnished to Lenders by or on behalf of Borrower in connection with
the Operative Documents or the transactions contemplated thereby are not to be
viewed as facts and that actual results
<PAGE>
 
during the period or periods covered by such projections may differ from the
projected or forecasted results.

     (m)   Certain Agreements of Officers, Employees and Consultants.
           ---------------------------------------------------------
           (i)   No officer, employee or consultant of Borrower is, or is now
expected to be, in violation of any term of any employment contract, proprietary
information agreement, nondisclosure agreement, noncompetition agreement, or any
other contract or agreement or any restrictive covenant relating to the right of
any such officer, employee or consultant to be employed by Borrower because of
the nature of the business conducted or to be conducted by Borrower or relating
to the use of trade secrets or proprietary information of others, and to the
best of Borrower's knowledge, after due inquiry, the continued employment of
Borrower's officers, employees and consultants do not subject Borrower to any
liability for any claim or claims arising out of or in connection with any such
contract, agreement, or covenant.

           (ii)   To the knowledge of Borrower, no officers of Borrower, and no
employee or consultant of Borrower whose termination, either individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect,
has any present intention of terminating his or her employment or consulting
relationship with Borrower.

provide Lenders with an Officer's Certificate of Borrower setting forth the
facts relating to or giving rise to such Default or Event of Default and the

subject to the observance and performance of the terms of this Agreement.

     V.4.  Location of Collateral.  The Collateral is and shall remain in the
           ----------------------

hereunder shall be subordinate to the Liens of existing and future lenders
providing equipment financing and equipment lessors, and to the Lien of Silicon
Valley Bank; provided that, in the case of equipment financings and leasing,
             --------

lessors  and Lenders' rights and remedies hereunder shall not in any way be
subordinate to the rights and remedies of any such lenders or equipment lessors.
Lenders agree to execute and deliver such agreements and documents as may be
reasonably requested by Borrower from time to time which set forth the lien
subordination described in this Section 5.05 and are reasonably acceptable to
                                ------------

become a Lien upon any of its properties; provided that there shall be no
                                          --------                       
requirement to pay any such tax, assessment, charge, levy or claim (i) which is

financial statements.

     (b)  Inspection Rights.  Borrower shall, at any reasonable time and from
          -----------------

relating in each case to Lenders' capacity as lenders and secured party

     (c)  Maintenance of Equipment and Similar Assets.  Borrower shall keep and
          -------------------------------------------                          
maintain all items of equipment and other similar types of personal property
that form any significant portion or portions of the Collateral in good
operating condition and repair and shall make all necessary replacements thereof
and
<PAGE>
 
renewals thereto so that the value and operating efficiency thereof shall at all
times be maintained and preserved. Borrower shall not permit any such material
item of Collateral to become a fixture to real estate or an accession to other
personal property, without the prior written consent of Lenders. Borrower shall
not permit any such material item of Collateral to be operated or maintained in
violation of any applicable law, statute, rule or regulation. With respect to
items of leased equipment (to the extent Lenders have any security interest in
any residual Borrower's interest in such equipment under the lease), Borrower
shall keep, maintain, repair, replace and operate such leased equipment in
accordance with the terms of the applicable lease.

     (d)  Insurance.

commercial general liability insurance (including contractual liability,
products liability and completed operations coverages) reasonably satisfactory
to Lenders, and (z) such other insurance against such other risks of loss and
with such terms, as shall in each case be reasonably satisfactory to or
reasonably required by Lenders (as to carriers, amounts and otherwise).  The
amount of the "all risk" insurance shall be determined to Lenders' reasonable
satisfaction as of each anniversary date of this Agreement and the appropriate
amount of coverage shall be put in effect on the next succeeding renewal or
inception date of such insurance.

          (ii) The deductible with respect to "all-risk" insurance required by
clause (x) above and product liability insurance required by clause (y) above
shall not exceed $25,000; otherwise there shall be no deductible with respect to
any insurance required to be maintained hereunder.  The amount of commercial
general liability insurance (other than products liability coverage and
completed operations insurance) required by clause (y) above shall be at least
$5,000,000 per occurrence.  The amount of the products liability and completed
operations insurance required by clause (y) above shall be at least $5,000,000
per occurrence.  Each "all risk" policy shall:  (x) name Lenders as loss payees,
(y) provide for each insurer's waiver of its right of subrogation against
Lenders, and (z) provide that such insurance (A) shall not be invalidated by any
action of, or breach of warranty by, Borrower of a provision of any of its
insurance policies, and (B) shall waive set-off, counterclaim or offset against
Lenders.  Each liability policy shall (w) name Lenders as additional insureds in
the full amount of Borrower's liability coverage limits (or the coverage limits
of any successor to Borrower or such successor's parent which is providing
coverage) and (x) provide that such insurance shall have cross-liability and
severability of interest endorsements (which shall not increase the aggregate
policy limits of Borrower's insurance).  All insurance policies shall (y)
provide that Borrower's insurance shall be primary without a right of
contribution of Lenders' insurance, if any, or any obligation on the part of
Lenders to pay premiums of Borrower, and (z) shall contain a clause requiring
the insurer to give Lenders at least 30 days' prior written notice of its
cancellation (other than cancellation for non-payment for which 10 days' notice
shall be sufficient).  Borrower shall on or prior to the first Funding Date and
prior to each policy renewal, furnish to Lenders certificates of insurance or
other evidence satisfactory to Lenders that such insurance coverage is in
effect.

or (j) of Section 9.01 shall occur and be continuing, Lenders may (i) declare
- ------    ------------

     (b)  If an Event of Default specified under clause (h) or (i) of Section
                                                 ----------------------------
9.01 shall occur, then immediately and without notice (i) the Loan, together
- ----

     IX.3.     Rights Regarding Collateral.  Borrower agrees that when any Event
               ---------------------------
of Default has occurred 
<PAGE>
 
and is continuing, Lenders shall have the rights, options, duties and remedies
of a secured party as permitted by law and, in addition to and without limiting
the foregoing, Lenders may exercise any one or more or all, and in any order, of
the remedies herein set forth, including the following:

     (a)  Lenders, personally or by agents or attorneys, shall have the right
(subject to compliance with any applicable mandatory legal requirements) to
require Borrower to assemble the Collateral and make it available to Lenders at
a place to be designated by Lenders or to take immediate possession of the
Collateral, or any portion thereof, and for that purpose may pursue the same
wherever it may be found, and may enter any of premises of Borrower, with or
without notice, demand, process of law or legal procedure, to the extent
permitted by applicable law, and search for, take possession of, remove, keep
and store the same, or use and operate or lease the same until sold. In
furtherance of Lenders' rights hereunder, Borrower hereby grants to Lenders an
irrevocable, non-exclusive license (exercisable without royalty or other payment
by Lenders) to use, license or sublicense any patent, trademark, trade name,
copyright or other intellectual property in which Borrower now or hereafter has
any right, title or interest together with the right of access to all media in
which any of the foregoing may be recorded or stored; provided, however, that
such license shall only be exercisable in connection with the disposition of
Collateral upon Lenders' exercise of their remedies hereunder.

     (b)  Lenders may, if at the time such action may be lawful and always
subject to compliance with any mandatory legal requirements, either with or
without taking possession and either before or after taking possession, without
instituting any legal proceedings whatsoever, having first given notice of such
sale by registered or certified mail to Borrower once at least ten (10) days
prior to the date of such sale, and having first given any other notice which
may be required by law, sell and dispose of the Collateral, or any part thereof,
at a private sale or at public auction, to the highest bidder, in one lot as an
entirety or in separate lots, and either for cash or on credit and on such terms
as Lenders may determine, and at any place (whether or not it be the location of
the Collateral or any part thereof) designated in the notice referred to above.
To the extent permitted by applicable law, any such sale or sales may be
adjourned from time to time by announcement at the time and place appointed for
such sale or sales, or for any such adjourned sale or sales, without further
published notice, and Borrower, Lenders or the holder or holders of the Note, or
of any interest therein, may bid and become the purchaser at any such sale.

     (c)  Lenders may proceed to protect and enforce this Agreement and the
other Operative Documents by suit or suits or proceedings in equity, at law or
in bankruptcy, and whether for the specific performance of any covenant or
agreement herein contained or in execution or aid of any power herein granted;
or for foreclosure hereunder, or for the appointment of a receiver or receivers
for any real property security or any part thereof, or for the recovery of
judgment for the Obligations or for the enforcement of any other proper, legal
or equitable remedy available under applicable law.

     IX.4.     Waiver by Borrower.  Upon the occurrence of an Event of Default,
               ------------------
to the extent permitted by law, Borrower covenants that it will not at any time
insist upon or plead, or in any manner whatsoever claim or take any benefit or
advantage of, any stay or extension law now or at any time hereafter in force,
nor claim, take nor insist upon any benefit or advantage of or from any law now
or hereafter in force providing for the valuation or appraisement of the
Collateral or any part thereof prior to any sale or sales thereof to be made
pursuant to any provision herein contained, or to the decree, judgment or order
of any court of competent jurisdiction; nor, after such sale or sales, claim or
exercise any right under any statute now or hereafter made or enacted by any
state or otherwise to redeem the property so sold or any part thereof, and, to
the full extent legally permitted, except as to rights expressly provided
herein, hereby expressly waives for itself and on behalf of each and every
Person, except decree or judgment creditors of Borrower, acquiring
<PAGE>
 
any interest in or title to the Collateral or any part thereof subsequent to the
date of this Agreement, all benefit and advantage of any such law or laws, and
covenants that it will not invoke or utilize any such law or laws or otherwise
hinder, delay or impede the execution of any power herein granted and delegated
to Lenders, but will suffer and permit the execution of every such power as
though no such power, law or laws had been made or enacted.

     IX.5.     Effect of Sale.  Any sale, whether under any power of sale 
               --------------
available to Lenders or by virtue of judicial proceedings, shall operate to
divest all right, title, interest, claim and demand whatsoever, either at law or
in equity, of Borrower in and to the property sold, and shall be a perpetual
bar, both at law and in equity, against Borrower, its successors and assigns,
and against any and all persons claiming the property sold or any part thereof
under, by or through Borrower, its successors or assigns.

     IX.6.     Application of Collateral Proceeds.  The proceeds and/or avails 
               ----------------------------------
of the Collateral, or any part thereof, and the proceeds and the avails of any
remedy hereunder (as well as any other amounts of any kind held by Lenders at
the time of, or received by Lenders after, the occurrence of an Event of Default
hereunder) shall be paid to and applied as follows:

     (a)  First, to the payment of reasonable costs and expenses, including all
          -----                                                                
amounts expended to preserve the value of the Collateral, of foreclosure or
suit, if any, and of such sale and the exercise of any other rights or remedies,
and of all proper fees, expenses, liability and advances, including reasonable
legal expenses and attorneys' fees, incurred or made hereunder by Lenders;

     (b)  Second, to the payment to Lenders of the amount then owing or unpaid
          ------                                                              
on the Note, and in case such proceeds shall be insufficient to pay in full the
whole amount so due, owing or unpaid upon the Note, then first, to the unpaid
                                                         -----               
interest thereon, second, to unpaid principal thereof and third to the remaining
                  ------                                  -----                 
balance of the Obligations under the Note; such application to be made upon
presentation of the Note, and the notation thereon of the payment, if partially
paid, or the surrender and cancellation thereof, if fully paid;

     (c)  Third, to the payment of other amounts then payable to Lenders under
          -----                                                               
any of the Operative Documents; and

     (d)  Fourth, to the payment of the surplus, if any, to Borrower, its
          ------                                                         
successors and assigns, or to whomsoever may be lawfully entitled to receive the
same.

     IX.7.     Reinstatement of Rights.  If Lenders shall have proceeded to  
               -----------------------
enforce any right under this Agreement or any other Operative Document by
foreclosure, sale, entry or otherwise, and such proceedings shall have been
discontinued or abandoned for any reason or shall have been determined
adversely, then and in every such case (unless otherwise ordered by a court of
competent jurisdiction), Lenders shall be restored to their former position and
rights hereunder with respect to the property subject to the security interest
created under this Agreement.

                                 MISCELLANEOUS
                                 -------------


     X.1.      Modifications, Amendments or Waivers.  The provisions of any 
               ------------------------------------
Operative Document may be modified, amended or waived only by a written
instrument signed by the parties thereto.
<PAGE>
 
     X.2.      No Implied Waivers; Cumulative Remedies; Writing Required.  No
               ---------------------------------------------------------
delay or failure of Lenders in exercising any right, power or remedy hereunder
shall affect or operate as a waiver thereof; nor shall any single or partial
exercise thereof or any abandonment or discontinuance of steps to enforce such a
right, power or remedy preclude any further exercise thereof or of any other
right, power or remedy. The rights and remedies hereunder of Lenders are
cumulative and not exclusive of any rights or remedies which it would otherwise
have. Any waiver, permit, consent or approval of any kind or character on the
part of Lenders of any breach or default under this Agreement or any such waiver
of any provision or condition of this Agreement must be in writing and shall be
effective only in the specified instance and to the extent specifically set
forth in such writing.

     X.3.      Expenses; Indemnification.  Borrower agrees upon demand to pay
               -------------------------
or reimburse Lenders for all liabilities, obligations and out-of-pocket
expenses, including reasonable fees and expenses of counsel for Lenders, from
time to time arising in connection with the enforcement or collection of sums
due under the Operative Documents. Borrower shall indemnify, reimburse and hold
Lenders, each of Lenders' partners, and each of their respective successors,
assigns, agents, officers, directors, shareholders, servants, agents and
employees harmless from and against all liabilities, losses, damages, actions,
suits, demands, claims of any kind and nature (including claims relating to
environmental discharge, cleanup or compliance), all costs and expenses
whatsoever to the extent they may be incurred or suffered by such indemnified
party in connection therewith (including reasonable attorneys' fees and
expenses), fines, penalties (and other charges of applicable governmental
authorities), licensing fees relating to any item of Collateral, damage to or
loss of use of property (including consequential or special damages to third
parties or damages to Borrower's property), or bodily injury to or death of any
person (including any agent or employee of Borrower) (each, a "Claim"), directly
or indirectly relating to or arising out of the use of the proceeds of the Loan
or otherwise, the falsity of any representation or warranty of Borrower or
Borrower's failure to comply with the terms of this Agreement or any other
Operative Document during the Term. The foregoing indemnity shall cover, without
limitation, (i) any Claim in connection with a design or other defect (latent or
patent) in any item of equipment included in the Collateral, (ii) any Claim for
infringement of any patent, copyright, trademark or other intellectual property
right, (iii) any Claim resulting from the presence on or under or the escape,
seepage, leakage, spillage, discharge, emission or release of any Hazardous
Materials on the premises of Borrower, including any Claims asserted or arising
under any Environmental Law, or (iv) any Claim for negligence or strict or
absolute liability in tort; provided, however, that Borrower shall not indemnify
                            -----------------
Lenders for any liability incurred by Lenders as a direct and sole result of
Lenders' gross negligence or willful misconduct. Such indemnities shall continue
in full force and effect, notwithstanding the expiration or termination of this
Agreement. Upon Lenders' written demand, Borrower shall assume and diligently
conduct, at its sole cost and expense, the entire defense of Lenders, each of
its partners, and each of their respective, agents, employees, directors,
officers, shareholders, successors and assigns against any indemnified Claim
described in this Section 10.03. Borrower shall not settle or compromise any
                  -------------                                              
Claim against or involving Lenders without first obtaining Lenders' written
consent thereto, which consent shall not be unreasonably withheld.

     X.4.      Waivers.  (a) Borrower shall give Lenders written notice within
               -------
one hundred eighty (180) days of obtaining knowledge of the occurrence of any
claim or cause of action it believes it has, or may seek to assert to allege
against Lenders whether such claim is based in law or equity, arising under or
related to this Agreement or any of the other Operative Documents or to the
transactions contemplated hereby or thereby, or any act or omission to act by
Lenders with respect hereto or thereto, and that if it shall fail to give such
notice to Lenders with regard to any such claim or cause of action, Borrower
shall be deemed to have waived, and shall be forever barred from bringing or
asserting such claim or cause of action in any suit, action or proceeding in any
court or before any governmental agency or authority or any arbitrator.

(b) NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR
ANYWHERE ELSE, BORROWER AGREES THAT IT SHALL NOT SEEK FROM LENDERS UNDER ANY
THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY SPECIAL, INDIRECT,

Agreement between the Lenders, Borrower and each Lender acknowledge, understand
and agree that:

     (a)  The relationship between the Borrower, on the one hand, and Lenders,
on the other, is, and at all time shall remain solely that of a borrower and
lenders.  Lenders shall not under any circumstances be construed to be partners
or joint venturers of Borrower or any of its Affiliates; nor shall Lenders under
any circumstances be deemed to be in a relationship of confidence or trust or a
fiduciary relationship with Borrower or any of its Affiliates, or to owe any
fiduciary duty to Borrower or any of its Affiliates.  Lenders do not undertake
or assume any responsibility or duty to Borrower or any of its Affiliates to
select, review, inspect, supervise, pass judgment upon or otherwise inform the
Borrower or any of its Affiliates of any matter in connection with its or their
Property, any Collateral held by any Lender or the operations of Borrower or any
of its Affiliates.  Borrower and each of its Affiliates shall rely entirely on
their own judgment with respect to such matters, and any review, inspection,
supervision, exercise of judgment or supply of information undertaken or assumed
by any Lender in connection with such matters is solely for the protection of
Lenders and neither Borrower nor any Affiliate is entitled to rely thereon.
<PAGE>

solely that of co-lenders.  Lenders shall not under any circumstances be
construed to be partners or joint venturers of each other; nor shall the Lenders
under any circumstances be deemed to be in a relationship of confidence or trust
or a fiduciary relationship with each other, or to owe any fiduciary duty to
each other.  Lenders do not undertake or assume any responsibility or duty to
each other to select, review, inspect, supervise, pass judgment upon or
otherwise inform each other of any matter in connection with Borrower or
Borrower's Property, any Collateral held by any Lender or the operations of
Borrower.  Each Lender shall rely entirely on its own judgment with respect to
such matters, and any review, inspection, supervision, exercise of judgment or
supply of information undertaken or assumed by any Lender in connection with
such matters is solely for the protection of such Lender.

     X.10.     Governing Law.  This Agreement, the other Operative Documents
               -------------
and the rights and obligations of the parties hereto and thereto shall be
governed by and construed and enforced in accordance with the laws of the State
of California. Any action to enforce this Agreement against Borrower may be
brought in California or, with regard to Collateral, may also be brought
wherever such Collateral is located.

     X.11.     Successors and Assigns.  This Agreement and the other Operative
               ----------------------
Documents shall be binding upon and inure to the benefit of Lenders, all future
holders of the Note, Borrower and their respective successors and permitted
assigns, except that Borrower may not assign or transfer its rights hereunder or
any interest herein without the prior written consent of Lenders; provided, that
the reincorporation of Borrower from a California corporation to a Delaware
corporation shall not be deemed an assignment or transfer under this Section
10.11. Lenders may sell to any other financial entity (a "Participant")
participation interests in Lenders' rights under this Agreement and the other
Operative Documents; provided that notwithstanding the sale of participations,
Lenders shall remain solely responsible for the performance of its obligations
under this Agreement, Lenders shall remain the holder of the Note for all
purposes under this Agreement and Borrower shall continue to deal solely and
directly with Lenders in connection with this Agreement and the other Loan
Documents. Lenders may disclose the Operative Documents and any other financial
or other information relating to Borrower or any Subsidiary to any potential
Participant, provided that such Participant agrees to protect the
confidentiality of such documents and information using the same measures that
it uses to protect its own confidential information.

     X.12.     Counterparts.  This Agreement may be executed in any number of
               ------------
counterparts and by different parties hereto on separate counterparts, each of
which, when so executed and delivered, shall be an original, but all such
counterparts shall together constitute one and the same instrument.

     X.13.     Further Assurances.  Borrower will, at its own expense, from 
               ------------------
time to time do, execute, acknowledge and deliver all further acts, deeds,
conveyances, transfers and assurances, and all financing and continuation
statements and similar notices, reasonably necessary or proper for the
perfection of the security interest being herein provided for in the Collateral,
whether now owned or hereafter acquired.

     X.14.     Power of Attorney in Respect of the Collateral.  Borrower does
               ----------------------------------------------

MMC/GATX Partnership No. I
c/o GATX Capital Corporation, Agent
Four Embarcadero Center
Suite 2200
San Francisco, California 94111

and

Transamerica Business Credit Corporation


Gentlemen:


          We have acted as counsel for EXODUS COMMUNICATIONS, INC. (the
"Borrower") in connection with (i) the execution of the Loan and Security
Agreement of even date herewith (the "Loan") between Borrower and MMC/GATX
Partnership No. I and TRANSAMERICA BUSINESS CREDIT CORPORATION ("Lenders"), (ii)
the issuance of two warrants to purchase Borrower's Series D Preferred Stock
(the "Warrants") and (iii) the transactions contemplated thereby.  This opinion
is being rendered to you pursuant to Section 8.01 of the Loan Agreement.
Capitalized terms not otherwise defined in this opinion have the meaning given
them in the Loan Agreement.

          In connection with this opinion and our representation, we have
examined originals, or copies certified or otherwise identified to our
satisfaction, of the following:

       (i)  The Loan Agreement;

      (ii)  The Warrants;

     (iii)  The Notes dated as of December 31, 1997;

      (iv)  The Restated Articles of Incorporation and the Bylaws of Borrower,
            each as in effect on the date hereof;

       (v)  The certificate of an officer of Borrower as to certain factual
            matters ("Officer Certificate");

      (vi)  Certificates issued by the Secretary of State of the State of
            California dated _______________________, _____, certifying the good
            standing of Borrower;

     (vii)  Such other documents, records, and certificates as we have deemed
            necessary or appropriate as a basis for the opinions hereafter
            expressed.

     The Loan Agreement, the Note and the Warrant are hereinafter referred to as
the "Transaction 
<PAGE>
 
Documents."

     In such examinations we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals and the conformity to
originals of all documents submitted to us as certified, facsimile, telecopied
or photostatic copies thereof.  As to certain matters of fact material to our
opinion, we have relied upon the Officer Certificate and upon your
representations in the Transaction Documents.

     As used in this opinion, the expression "to the best of our knowledge,"
means the actual present knowledge or belief of those attorneys in our firm who
have or who are currently representing Borrower.  We have not undertaken any
independent investigation to determine the existence or nonexistence of other
facts, and no inference as to our knowledge of the existence or nonexistence of
other facts should be drawn from the fact of this firm's representation of
Borrower in connection with the Transaction Documents.

     Based upon and subject to the foregoing and subject to the qualifications
contained herein, we are of the opinion that:

          (a) Borrower is a corporation duly organized, validly existing and in
good standing under the laws of the State of California.

          (b) Borrower has the requisite corporate power and authority to
execute, deliver and perform the Transaction Documents and to issue the Warrant.
All action on the part of Borrower, its directors and its shareholders necessary
for the authorization, execution, delivery and performance of the Transaction
Documents, has been taken.  The Transaction Documents have been duly executed
and delivered by an authorized officer of Borrower.

          (c) The execution, delivery and performance of the Transaction
Documents do not conflict with or violate any provision of Borrower's Restated
Articles of Incorporation or Bylaws or of applicable law and, to the best of our
knowledge, do not conflict with or constitute a default under any provision of
any judgment, writ, decree, order or material agreement, indenture, or
instrument to which Borrower is a party or by which it is bound.

          (d) The Transaction Documents constitute legal, valid and binding
obligations of Borrower, enforceable in accordance with their respective terms.
To our knowledge, no filing need be made with any governmental authority with
respect to the Transaction Documents in connection with an exemption from state
usury laws or in connection with any other matter.

          (e) The Series D Preferred Stock issuable upon exercise of the Warrant
have been duly authorized and reserved for issuance upon such exercise, and when
issued in accordance with the terms of the Warrant, will be duly authorized,
validly issued, fully paid and non-assessable.

          (f) The shares of Common Stock issuable upon conversion of the Series
D Preferred Stock into which the Warrant is convertible, have been duly
authorized and reserved and for issuance, when so issued in accordance with the
terms of Borrower's Restated Articles of Incorporation, will be validly issued,
fully paid and non-assessable.

          The opinions set forth above are subject to the following additional
qualifications, assumptions, limitations and exceptions:

          (A) The effect of bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium and other similar laws relating to or affecting the
rights and remedies of creditors generally.
<PAGE>
 
          (B) Limitations imposed by general equitable principles upon the
specific enforceability of any of the provisions of the Transaction Documents
and upon the availability of injunctive relief or other equitable remedies.

          (C) We express no opinion as to the enforceability of any choice of
law provision in the documents.

          (D) We express no opinion as to the compliance or noncompliance with
applicable antifraud statutes under the rules and regulations of state and
federal securities laws concerning the issuance of the Warrant.

          (E) We express no opinion herein concerning any law other than the law
of the State of California and the federal laws of the United States of America.

     This opinion is furnished to you solely for your benefit and may not be
relied upon by any other person (other than assignees of any of your rights)
without our prior written consent, which consent shall not be unreasonably
withheld or delayed.


                              Very truly yours,

operations and materials handled therein, and as a result thereof has reasonably

     7.1  EVENTS OF DEFAULT.   Upon the occurrence and during the continuation
of any Default, the obligation of Lender to make any additional Loan shall be
suspended.  The occurrence of any of the following shall terminate any

without notice of default, presentment or demand for payment, protest or notice

applicable law:

or appointment is acquiesced to by Borrower or is not dismissed within sixty
(60) days; or the dissolution or termination of the business of Borrower.

          (d) Borrower shall be in default beyond any applicable period of grace
or cure under any other agreement involving the borrowing of money, the purchase
of property, the advance of credit or any other monetary liability of any kind
to Lender or to any Person which results in the acceleration of payment of such
obligation in an amount in excess of One Hundred Thousand Dollars ($100,000).

          (e) Any governmental or regulatory authority shall take any judicial
or administrative action against Borrower, or any defined benefit pension plan
maintained by Borrower shall have any unfunded liabilities, any 
<PAGE>
 
of which, in the reasonable judgment of Lender, might have a Material Adverse
Effect

          (f) Any sale, transfer or other disposition of all or a substantial or
material part of the assets of Borrower, including without limitation to any
trust or similar entity, shall occur.

          (g) Any judgment(s) singly or in the aggregate in excess of One
Hundred Thousand Dollars ($100,000) shall be entered against Borrower which

outstanding shares of voting stock of Borrower

          (i) Borrower shall fail to perform any of its duties or obligations
under any Loan Document not specifically referenced in this Article 7, and such

                        ARTICLE 8 - GENERAL PROVISIONS
                                        
     8.1  NOTICES.    Any notice given by any party under any Loan Document
shall be in writing and personally delivered, sent by overnight courier, or
United States mail, postage prepaid, or sent by facsimile, to be promptly
confirmed in writing, or other authenticated message, charges prepaid, to the
other party's or parties' addresses shown on the signature pages hereto. Each
party may change the address or facsimile number to which notices, requests and
other communications are to be sent by giving written notice of such change to
each other party. Notice given hand delivery shall be deemed received on the
date delivered; if sent by overnight courier, on the next business day after
delivery to the courier service; if by first class mail, on the third business
day after deposit in the U.S. Mail; and if by telecopy, on the date of
transmission.

     8.2  BINDING EFFECT.    The Loan Documents shall be binding upon and inure
to the benefit of Borrower and Lender and their respective successors and
assigns; provided, however, that Borrower may not assign or transfer Borrower 5
rights or obligations under any Loan Document without each Lender's prior
written consent. Lender reserves the right to sell, assign, transfer, negotiate
or grant participations in all or any part of, or any interest in, Lender's
rights and obligations under the Loan Documents. In connection with any of the
foregoing, Lender may disclose all documents and information which Lender now or
hereafter may have relating to the Loans, Borrower, or its business.

     8.3  NO WAIVER.    Any waiver, consent or approval by Lender of any Event
of Default or breach of any provision, condition, or covenant of any Loan
Document must be in writing and shall be effective only to the extent set forth
in writing. No waiver of any breach or default shall be deemed a waiver of any
later breach or default of the same or any other provision of any Loan Document.
No failure or delay on the part of Lender in exercising any power, right, or
privilege under any Loan Document shall operate as a waiver thereof, and no
single or partial exercise of any such power, right, or privilege shall 
<PAGE>
 
preclude any further exercise thereof or the exercise of any other power, right
or privilege.  Lender has the right at its sole option to continue to accept
interest and/or principal payments due under the Loan Documents after default,
and such acceptance shall not constitute a waiver of said default or an
extension of the Maturity Date unless Lender agrees otherwise in writing.

     8.4  RIGHTS CUMULATIVE.  All rights and remedies existing under the Loan
Documents are cumulative to, and not exclusive of, any other rights or remedies
available under contract or applicable law.

     8.5  UNENFORCEABLE PROVISIONS.     Any provision of any Loan Document
executed by Borrower which is prohibited or unenforceable in any jurisdiction,
shall be so only as to such jurisdiction and only to the extent of such
prohibition or unenforceability, but all the remaining provisions of any such
Loan Document shall remain valid and enforceable.

      8.6 ACCOUNTING TERMS.  Except as otherwise provided in this Agreement,
accounting terms and financial covenants and information shall be determined and
prepared in accordance with GAAP.

     8.7  INDEMNIFICATION; EXCULPATION.    Provided Borrower is given reasonable
notice and an opportunity to control any action or proceeding, Borrower shall
pay and protect, defend and indemnify Lender and Lender's employees, officers,
directors, shareholders, affiliates, correspondents, agents and representatives
(other than Lender, collectively "Agents") against, and hold Lender and each
such Agent harmless from, all claims, actions, proceedings, liabilities,
damages, losses, expenses (including, without limitation, attorneys' fees and
costs) and other amounts incurred by Lender and each such Agent, arising from
(i) the matters contemplated by this Agreement or any other Loan Documents or
(ii) any contention that Borrower has failed to comply with any law, rule,
regulation, order or directive applicable to Borrower's business; provided,
however, that this indemnification shall not apply to any of the foregoing
incurred solely as the result of Lender's or any Agent's gross negligence or
willful misconduct.  This indemnification shall survive the payment and
satisfaction of all of Borrower's obligations to Lender.  Notwithstanding the
forgoing, Borrower shall not be liable under this Section 8.7 or otherwise for
any form of special, incidental, indirect, consequential or punitive damages,
whether or not foreseen, whether based on breach of contract or otherwise.
Borrower 5 minimum liability, arising from or related to this Agreement shall
not exceed the aggregate of all monies borrowed hereunder from Lender, including
accrued but unpaid interest.

     8.8  REIMBURSEMENT.    Borrower shall reimburse Lender for all costs and
expenses, including without limitation reasonable attorneys' fees and
disbursements expended or incurred by Lender in any arbitration, mediation,
judicial reference or legal action in connection with (a) the preparation,
negotiation, amendment, interpretation and enforcement of the Loan Documents,
including without limitation during any workout, attempted workout, and/or in
connection with the rendering of legal advice as to Lender's rights, remedies
and obligations under the Loan Documents, (b) collecting any sum which becomes
due Lender under any Loan Document, (c) any proceeding for declaratory relief,
any counterclaim to any proceeding, or any appeal, or (d) the protection,
preservation or enforcement of any rights of Lender.  For the purposes of this
section, attorneys' fees shall include, without limitation, fees incurred in
connection with the following:  (1) contempt proceedings; (2) discovery; (3)
<PAGE>
 
any motion, proceeding or other activity of any kind in connection with an
Insolvency Proceeding; (4) garnishment, levy, and debtor and third party
examinations; and (5) postjudgment motions and proceedings of any kind,
including without limitation any activity taken to collect or enforce any
judgment.  All of the foregoing costs and expenses shall be payable upon demand
by Lender, and if not paid within forty-five (45) days of presentation of
invoices shall bear interest at the highest applicable Default Rate.
Notwithstanding the foregoing, Borrower shall not be liable to Lender under this
Section 8.8 for any action or dispute that is resolved favorably for Borrower.

     8.9  EXECUTION IN COUNTERPARTS.  This Agreement may be executed in any
number of counterparts which, when taken together, shall constitute but one
agreement.

     8.10 ENTIRE AGREEMENT.   The Loan Documents are intended by the parties as
the final expression of their agreement and therefore contain the entire
agreement between the parties and supersede all prior understandings or
agreements concerning the subject matter hereof.  This Agreement may be amended
only in a writing signed by Borrower and Lender.

     8.11 GOVERNING LAW AND JURISDICTION.

          (a) THIS AGREEMENT AND THE LOAN DOCUMENTS SHALL BE GOVERNED BY, AND
     CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA.

     DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT,
     EACH OF BORROWER AND LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS
     PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS.  EACH OF

     OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
     CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY
     ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS AGREEMENT OR
     ANY DOCUMENT RELATED HERETO.  BORROWER AND LENDER EACH WAIVE PERSONAL
     SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY
     ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

     8.12 WAIVER OF JURY TRIAL.   BORROWER AND LENDER EACH WAIVES ITS
RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON
OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER
LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR
ANY PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT
CLAIMS, OR OTHERWISE.  BORROWER AND LENDER EACH AGREES THAT ANY SUCH CLAIM OR
CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING
THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL
BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR
OTHER PROCEEDING WHICH SEEMS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR
ENFORCEABILITY OF THIS AGREEMENT OR THE
<PAGE>
 
OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.  THIS WAIVER SHALL

hereof until maturity, whether scheduled or accelerated, at a fixed rate per
annum of _____________ percent (___%) , and with Additional Interest in the sum

     This Note is one of the Notes referred to in, and is entitled to all the
benefits of, a Loan Agreement dated ___________________, 199__ , between
Borrower and Lender.  Each capitalized term not otherwise defined herein shall
have the meaning set forth in the Loan Agreement.  The Loan Agreement contains

of certain stated events.

     Principal of and interest on this Note shall be payable as follows:

     On the Borrowing Date, Borrower shall pay (i) Basic Interest, in advance,
on the outstanding principal balance of this Note at the Designated Rate for the

a rate per annum equal to the Default Rate.  Borrower shall pay such interest on
demand.

obligated to pay interest, charges or fees at a rate in excess of the highest
rate permitted by applicable law from time to time in effect.

failure remains uncured for ten (10) or more days after notice to Debtor;

<PAGE>
 
Party's option, without notice or demand of any kind, (a) declare all or any

judgment or decree of a court of competent jurisdiction.

after the occurrence of an Event of Default Debtor will:

of Secured Party for rent or other compensation for the use of Debtor's
premises.

     7.1  PERFORMANCE OF DEBTOR'S OBLIGATIONS.  Without having any obligation to
do so, Secured Party may perform or pay any obligation which Debtor has agreed
to perform or pay under this Agreement, including, without limitation, the
payment or discharge of taxes or Liens levied or placed on or threatened against
the Collateral.  In so performing or paying, Secured Party shall determine the
action to be taken and the amount necessary to discharge such obligations.
Debtor shall reimburse Secured Party on demand for any amounts paid by Secured
Party pursuant to this Section, which amounts shall constitute Indebtedness
secured by the Collateral and shall bear interest from the date of demand at the
rate applicable to overdue payments under the Loan Agreement.

     7.2  POWER OF ATTORNEY.  For the purpose of protecting, preserving and
enforcing the Collateral and Secured Party's rights under this Agreement, Debtor
hereby irrevocably appoints Secured Party, with full power of substitution, as
its attorney-in-fact with full power and authority to do any act which Debtor is
obligated to do, or Secured Party has the right to do, hereunder; to exercise
such rights with respect to the Collateral as Debtor might exercise; to use such
Collateral; to enter Debtor's premises; to give notice of Secured Party's
security interest in and to collect the Collateral and the Proceeds; and to
execute and file in Debtor's name any financing statements, amendments and
continuation statements necessary or desirable to perfect or continue the
perfection of Secured Party's security interests in the Collateral.  Debtor
hereby ratifies all that Secured Party shall lawfully do or cause to be done by
virtue of this appointment.

     7.3  AUTHORIZATION FOR SECURED PARTY TO TAKE CERTAIN ACTION. The power of
attorney created in Section 7.3 is a power coupled with an interest and shall be
irrevocable.  The powers conferred on Secured Party hereunder are solely to
protect its interests in the Collateral and shall not impose any duty upon
Secured Party to exercise such powers.  Secured Party shall be accountable only
for amounts that it actually receives as a result of the exercise of such powers
and in no event shall Secured Party or any of its directors, officers,
employees, agents or representatives be responsible to Debtor for any act or
failure to act, except for gross negligence or willful misconduct.  Secured
Party may exercise this power of attorney without notice to or assent of Debtor,
in the name of Debtor, or in Secured Party's own name, from time to time in
Secured Party's sole discretion and at Debtor's expense.  To further carry out
the terms of this Agreement, Secured Party may upon the occurrence of an Event
of Default:
<PAGE>
 
          (A) Execute any statements or documents to take possession of, and
endorse and collect and receive delivery or payment of, any checks, drafts,
notes, acceptances or other instruments and documents constituting the payment
of amounts due and to become due or any performance to be rendered with respect
to the Collateral;

          (B) Sign and endorse any invoices, freight or express bills, bills of
lading, storage or warehouse receipts; drafts, certificates and statements under
any commercial or standby letter of credit, assignments, leases, bills of sale,
or any other documents relating to the Collateral, including without limitation
the Records;

          (C) Use or operate Collateral or any other property of Debtor for the
purpose of preserving or liquidating Collateral;

          (D) File any claim or take any other action or proceeding in any court
of law or equity or as otherwise deemed appropriate by Secured Party for the
purpose of collecting any and all monies due or securing any performance to be
rendered with respect to the Collateral;

          (E) Commence, prosecute or defend any suits, actions or proceedings or
as otherwise deemed appropriate by Secured Party for the purpose of protecting
or collecting the Collateral. In furtherance of this right, upon the occurrence
of an Event of Default Secured Party may apply for the appointment of a receiver
or similar official to operate Debtor's business, and, to the fullest extent
permitted by law, Debtor hereby waives any right to oppose such appointment;

          (F) Prepare, adjust, execute, deliver and receive payment under
insurance claims, and collect and receive payment of and endorse any instrument
in payment of loss or returned premiums or any other insurance refund or return,
and apply such amounts, at Secured Party's sole discretion, toward repayment of
the Indebtedness or replacement of the Collateral.

     7.4  APPLICATION OF PROCEEDS.  Any Proceeds and other monies or property
received by Secured Party pursuant to the terms of this Agreement or any Loan
Document may be applied by Secured Party first to the payment of expenses of
collection, including without limitation to reasonable attorneys' fees, and then
to the payment of the Indebtedness in such order of application as Secured Party
may elect.  Notwithstanding the rights given to Debtor pursuant  to California
Civil Code sections 1479 and 2822 or equivalent provisions in the laws of the
state specified in the governing law clause of this document (and any amendments
or successors thereto), to designate how payments will be applied, Debtor hereby
waives such rights and Secured Party shall have the right in its sole discretion
to determine the order and method of
<PAGE>
 
the application of payments received from Debtor or from the sale or disposition
of the Collateral and to revise such application prospectively or retroactively
at its discretion.

     7.5  DEFICIENCY.  If the proceeds of any sale of the Collateral are
insufficient to cover all costs and expenses of such sale and the payment in
full of all Indebtedness, plus all other sums required to be expended or
distributed by Secured Party, then Debtor shall be liable for any such
deficiency.

     7.6  SECURED PARTY TRANSFER.  Upon the transfer of all or any part of the
Indebtedness, Secured Party may transfer all or any part of its interest in the
Collateral and shall be fully discharged thereafter from all liability and
responsibility with respect to such interest in the Collateral so transferred,
and the transferee shall be vested with all the rights and powers of Secured
Party hereunder with respect to such interest in the Collateral so transferred.


                        ARTICLE 8 - GENERAL PROVISIONS
                                        
     8.1  NOTICES.  Any notice given by any party under this Agreement shall be
given in the manner prescribed in the Loan Agreement.

permitted successors, representatives and assigns, and shall inure to the
benefit of Secured Party and its successors, representatives and assigns;
provided however that Debtor may not assign or transfer Debtor's obligations
under this Agreement without Secured Party's prior written consent.  Secured
Party reserves the right to sell, assign, or transfer its rights and powers
under this Agreement in whole or in part without notice to Debtor.  In that
connection, Secured Party may disclose all documents and information which
Secured Party now or hereafter may have relating to this Agreement, Debtor or
Debtor's business.

     8.3  NO WAIVER.  Any waiver, consent or approval by Secured Party of any
Event of Default or breach of any provision, condition or covenant of this
Agreement or any Loan Document must be in writing and shall be effective only to
the extent set forth in writing.  No waiver or any breach of default shall be
deemed a waiver of any later breach or default of the same or any other
provision of this Agreement or any of the Loan Documents.  No failure or delay
on the part of Secured Party in exercising any power, right or privilege under
this Agreement or any Loan Document shall operate as a waiver thereof, and no
single or partial exercise of any such power, right or privilege shall preclude
any further exercise thereof, or the exercise of any further power, right or
privilege.
<PAGE>
 
     8.4  RIGHTS CUMULATIVE.  All rights and remedies existing under this
Agreement are cumulative to, and not exclusive of, any other rights or remedies
available under contract or applicable law.

     8.5  UNENFORCEABLE PROVISIONS.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall be so only as to such
jurisdiction and only to the extent of such prohibition or unenforceability, but
all the remaining provisions of this Agreement shall remain valid and
enforceable.

     8.6  GOVERNING LAW, WAIVER OF NOTICE.  Except as nay be otherwise provided
by the Uniform Commercial Code or in any addendum hereto, this Agreement shall
be governed by and construed in accordance with the laws of the State of
California. To the fullest extent permitted by law, Debtor hereby waives
presentment, demand, protest, notice of dishonor and all other notices and
demands as well as any applicable statute of limitations.

     8.7  ENTIRE AGREEMENT.  This Agreement, together with the other Loan
Documents, is intended by Debtor and Secured Party as the final expression of
Debtor's obligations to Secured Party in connection with the Collateral and
supersedes all prior understandings or agreements concerning the subject matter
hereof.  This Agreement may be amended only by a writing signed by Debtor and
accepted by Secured Party in writing.


IN WITNESS WHEREOF, the parties have executed this Agreement as of the date set

          This Warrant is subject to the following terms and conditions:

     1.   Exercise; Issuance of Certificates; Payment for Shares.
          ------------------------------------------------------

          (a)  Unless an election is made pursuant to clause (b) of this Section
1, this Warrant shall be exercisable at the option of the Holder, at any time or
from time to time, on or before the Expiration Date for all or any portion of
the shares of Preferred Stock (but not for a fraction of a share) which may be
purchased hereunder for the Stock Purchase Price multiplied by the number of
shares to be purchased. In the event, however, that pursuant to the Company's
Articles of Incorporation, as amended, an event
<PAGE>
 
causing automatic conversion of the Company's Preferred Stock shall have
occurred prior to the exercise of this warrant, in whole or in part, then this
Warrant shall be exercisable for the number of shares of Common Stock of the
Company into which the Preferred Stock not purchased upon any prior exercise of
the Warrant would have been so converted (and, where the context requires,
reference to "Preferred Stock" shall be deemed to include such Common Stock).
The Company agrees that the shares of Preferred Stock purchased under this
Warrant shall be and are deemed to be issued to the holder hereof as the record
owner of such shares as of the close of business on the date on which this
Warrant shall have been surrendered and payment made for such shares. Subject to
the provisions of Section 2, certificates for the shares of Preferred Stock so
purchased, together with any other securities or property to which the Holder
hereof is entitled upon such exercise, shall be delivered to the Holder hereof
by the Company at the Company's expense within a reasonable time after the
rights represented by this Warrant have been so exercised. Except as provided in
clause (b) of this Section 1, in case of a purchase of less than all the shares
which may be purchased under this Warrant, the Company shall cancel this Warrant
and execute and deliver a new Warrant or Warrants of like tenor for the balance
of the shares purchasable under the Warrant surrendered upon such purchase to
the Holder hereof within a reasonable time. Each stock certificate so delivered
shall be in such denominations of Preferred Stock as may be reasonably requested
by the Holder hereof and shall be registered in the name of such Holder or such
other name as shall be designated by such Holder, subject to the limitations
contained in Section 2.

          (b)  The Holder, in lieu of exercising this Warrant by the payment of
the Stock Purchase Price pursuant to clause (a) of this Section 1, may elect, at
any time on or before the Expiration Date, to receive that number of shares of
Preferred Stock equal to the quotient of: (i) the difference between (A) the Per
Share Price (as hereinafter defined) of the Preferred Stock, less (B) the Stock
Purchase Price then in effect, multiplied by the number of shares of Preferred
Stock the Holder would otherwise have been entitled to purchase hereunder
pursuant to clause (a) of this Section 1 (or such lesser number of shares as the
Holder may designate in the case of a partial exercise of this Warrant); over
(ii) the Per Share Price.

          (c)  For purposes of clause (b) of this Section 1, "Per Share Price"
means the product of:  (i) the greater of (A)  the average of the closing bid
and asked prices of the Company's Common Stock as quoted by NASDAQ or listed on
any exchange, whichever is applicable, as published in the Western Edition of
The Wall Street Journal for the ten (10) trading days prior to the date of the
- -----------------------
Holder's election hereunder or, (B) if applicable at the time of or in

                                       2
<PAGE>
 
connection with the exercise under clause (b) of this Section 1, the gross sales
price of one share of the Company's Common Stock pursuant to a registered public
offering or that amount which shareholders of the Company will receive for each
share of Common Stock pursuant to a merger, reorganization or sale of assets;
and (ii) that number of shares of Common Stock into which each share of
Preferred Stock is convertible. If the Company's Common Stock is not quoted by
NASDAQ or listed on an exchange, the Per Share Price of the Preferred Stock (or
the equivalent number of shares of Common Stock into which such Preferred Stock
is convertible) shall be the price per share which the Company would obtain from
a willing buyer for shares sold by the Company from authorized but unissued
shares as such price shall be agreed upon by the Holder and the Company or, if
agreement cannot be reached within ten (10) business days of the Holder's
election hereunder, as such price shall be determined by a panel of three (3)
appraisers, one (1) to be chosen by the Company, one (1) to be chosen by the
Holder and the third to be chosen by the first two (2) appraisers. If the
appraisers cannot reach agreement within 30 days of the Holder's election
hereunder, then each appraiser shall deliver its appraisal and the appraisal
which is neither the highest nor the lowest shall constitute the Per Share
Price. In the event either party fails to choose an appraiser within 30 days of
the Holder's election hereunder, then the appraisal of the sole appraiser shall
constitute the Per Share Price. Each party shall bear the cost of the appraiser
selected by such party and the cost of the third appraiser shall be borne 
one-half by each party. In the event either party fails to choose an appraiser,
the cost of the sole appraiser shall be borne one-half by each party.

     2.   Limitation on Transfer.
          -----------------------

          (a)  The Warrant and the Preferred Stock shall not be transferable
except upon the conditions specified in this Section 2, which conditions are
intended to insure compliance with the provisions of the Securities Act.  Each
holder of this Warrant or the Preferred Stock issuable hereunder will cause any
proposed transferee of the Warrant or Preferred Stock to agree to take and hold
such securities subject to the provisions and upon the conditions specified in
this Section 2.

          (b)  Each certificate representing (i) this Warrant, (ii) the
Preferred Stock, (iii) shares of the Company's Common Stock issued upon
conversion of the Preferred Stock and (iv) any other securities issued in
respect of the Preferred Stock or Common Stock issued upon conversion of the
Preferred Stock upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of this Section 2 or unless such securities have been registered

                                       3
<PAGE>
 
under the Securities Act or sold under Rule 144) be stamped or otherwise
imprinted with a legend substantially in the following form (in addition to any
legend required under applicable state securities laws):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR
     ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED
     IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID
     ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

          (c)  The Holder of this Warrant and each person to whom this Warrant
is subsequently transferred represents and warrants to the Company (by
acceptance of such transfer) that it will not transfer the Warrant (or
securities issuable upon exercise hereof unless a registration statement under
the Securities Act was in effect with respect to such securities at the time of
issuance thereof) except pursuant to (i) an effective registration statement
under the Securities Act, (ii)  Rule 144 under the Securities Act (or any other
rule under the Securities Act relating to the disposition of securities), or
(iii) an opinion of counsel, reasonably satisfactory to counsel for the Company,
that an exemption from such registration is available. This Warrant may be
transferred in whole and not in part, except that it may be transferred in part
only to affiliates of the Initial Holder, all pursuant to the other restrictions
or transfer declared in this Section 2.

     3.   Shares to be Fully Paid; Reservation of Shares. The Company covenants
          ----------------------------------------------
and agrees that all shares of Preferred Stock which may be issued upon the
exercise of the rights represented by this Warrant will, upon issuance, be duly
authorized, validly issued, (assuming appropriate consideration is tendered by
the Holder to the Company) fully paid and nonassessable and free from all
preemptive rights of any shareholder and free of all taxes, liens and charges
with respect to the issue thereof.  The Company further covenants and agrees
that during the period within which the rights represented by this Warrant may
be exercised, the Company will at all times have authorized and reserved, for
the purpose of issue or transfer upon exercise of the subscription rights
evidenced by this Warrant, a sufficient number of shares of authorized but
unissued Preferred Stock, or other securities and property, when and as required
to provide for the exercise of the rights represented by this Warrant.  The
Company will take all such action as may be necessary to assure that such shares
of Preferred Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Preferred Stock or other securities into which this
Warrant is ultimately

                                       4
<PAGE>
 
convertible may be listed.  The Company will not take any action which would
result in any adjustment of the Stock Purchase Price (as defined in Section 4
hereof) (i) if the total number of shares of Preferred Stock issuable after such
action upon exercise of all outstanding warrants, together with all shares of
Preferred Stock then outstanding and all shares of Preferred Stock then issuable
upon exercise of all options and upon the conversion of all convertible
securities then outstanding, would exceed the total number of shares of
Preferred Stock then authorized by the company's Articles of Incorporation, or
(ii) if the total number of shares of Common Stock issuable after such action
upon the conversion of all such shares of Preferred Stock together with all
shares of Common Stock then outstanding and then issuable upon exercise of all
options and upon the conversion of all convertible securities then outstanding
would exceed the total number of shares of Common Stock then authorized by the
Company's Articles of Incorporation.

     4.   Adjustment of Stock Purchase Price Number of Shares.  The Stock
          ---------------------------------------------------
Purchase Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 4.  Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the number
of shares obtained by multiplying the Stock Purchase Price in effect immediately
prior to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock.  In case the Company shall
               -----------------------------------
at any time subdivide its outstanding shares of Preferred Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Preferred Stock of the Company shall be combined into a
smaller number of shares, the Stock Purchase Price in effect immediately prior
to such combination shall be proportionately increased.

          4.2  Dividends in Preferred Stock, Other Stock, Property,
               ---------------------------------------------------
Reclassification.  If at any time or from time to time the holders of Preferred
- ----------------
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor,

          (a)  Preferred Stock, or any shares of stock or other securities
whether or not such securities are at any time directly or indirectly
convertible into or exchangeable for Preferred Stock, or any rights or options
to subscribe

                                       5
<PAGE>
 
for, purchase or otherwise acquire any of the foregoing by way of dividend or
other distribution, or

               (b)  any cash paid or payable otherwise than as a cash dividend,
or

               (c)  Preferred Stock or other or additional stock or other
securities or property (including cash) by way of spinoff, split-up,
reclassification, combination of shares or similar corporate rearrangement,
(other than shares of Preferred Stock issued as a stock split, adjustments in
respect of which shall be covered by the terms of Section 4.1 above), then and
in each such case, the Holder hereof shall, upon the exercise of this Warrant,
be entitled to receive, in addition to the number of shares of Preferred Stock
receivable thereupon, and without payment of any additional consideration
therefore, the amount of stock and other securities and property (including cash
in the cases referred to in clauses (b) and (c) above) which such Holder would
hold on the date of such exercise had he been the holder of record of such
Preferred Stock as of the date on which holders of Preferred Stock received or
became entitled to receive such shares and/or all other additional stock and
other securities and property.

          4.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
               ---------------------------------------------------------------
If any capital reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale of
all or substantially all of its assets to another corporation shall be effected
in such a way that holders of Preferred Stock shall be entitled to receive
stock, securities or assets with respect to or in exchange for Preferred Stock,
then, as a condition of such reorganization, reclassification, consolidation,
merger or sale, lawful and adequate provisions shall be made whereby the holder
hereof shall thereafter have the right to purchase and receive(in lieu of the
shares of the Preferred Stock of the Company immediately theretofore purchasable
and receivable upon the exercise of the rights represented hereby) such shares
of stock, securities or assets as may be issued or payable with respect to or in
exchange for a number of outstanding shares of such Preferred Stock equal to the
number of shares of such stock immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby.  In any such
case, appropriate provision shall be made with respect to the rights and
interests of the holder of this Warrant to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Stock Purchase
Price and of the number of shares purchasable and receivable upon the exercise
of this Warrant) shall thereafter be applicable, as nearly as nay be possible,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise hereof.  The Company will not effect any such

                                       6
<PAGE>
 
consolidation, merger or sale unless, prior to the consummation thereof, the
successor corporation (if other than the Company) resulting from such
consolidation or the corporation purchasing such assets shall assume by written
instrument, executed and mailed or delivered to the registered Holder hereof at
the last address of such Holder appearing on the books of the Company, the
obligation to deliver to such Holder such shares of stock, securities or assets
as, in accordance with the foregoing provisions, such Holder may be entitled to
purchase.

          4.4  Notice of Adjustment.  Upon any adjustment of the stock Purchase
               --------------------
Price, and/or any increase or decrease in the number of shares purchasable upon
the exercise of this Warrant the Company shall give written notice thereof, by
first class mail, postage prepaid, addressed to the registered holder of this
Warrant at the address of such holder as shown on the books of the Company.  The
notice shall be signed by the Company's chief financial officer and shall state
the Stock Purchase Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

          4.5  Other Notices.  If at any time:
               -------------

               (a)  the Company shall declare any cash dividend upon its
Preferred stock;

               (b)  the Company shall declare any dividend upon its Preferred
Stock payable in stock or make any special dividend or other distribution to the
holders of its Preferred Stock;

               (c)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, or consolidation or merger
of the Company with, or sale of all or substantially all of its assets to,
another corporation;

               (d)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; or

               (e)  the Company shall take or propose to take any other action,
notice of which is actually provided to holders of the Preferred Stock;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, addressed to the holder of this Warrant at the address of
such holder as shown on the books of the Company, (i) at least 10 day's prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividend,


                                       7
<PAGE>
 
distribution or subscription rights or for determining rights to vote in respect
of any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding-up, or other action and (ii) in the case of
any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding-up, or other action, at least 10 day's
written notice of the date when the same shall take place.  Any notice given in
accordance with the foregoing clause (i) shall also specify, in the case of any
such dividend, distribution or subscription rights, the date on which the
holders of Preferred Stock shall be entitled thereto.  Any notice given in
accordance with the foregoing clause (ii) shall also specify the date on which
the holders of Preferred Stock shall be entitled to exchange their Preferred
Stock for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action as the case may be.

          4.6  Certain Events.  If any change in the outstanding Preferred Stock
               --------------
of the Company or any other event occurs as to which the other provisions of
this Section 4 are not strictly applicable or if strictly applicable would not
fairly protect the purchase rights of the Holder of the Warrant in accordance
with the essential intent and principles of such provisions, then the Board of
Directors of the Company shall make an adjustment in the number and class of
shares available under the Warrant, the Stock Purchase Price and/or the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such purchase rights as aforesaid.  The adjustment
shall be such as will give the Holder of the Warrant upon exercise for the same
aggregate Stock Purchase Price the total number, class and kind of shares as he
would have owned had the Warrant been exercised prior to the event and had he
continued to hold such shares until after the event requiring adjustment.

     5.   Issue Tax.  The issuance of certificates for shares of Preferred Stock
          ---------
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax in respect thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Holder of the Warrant being exercised.

     6.   Closing of Books.   The Company will at no time close its transfer
          ----------------
books against the transfer of any Warrant or of any shares of Preferred  Stock
issued or issuable upon the exercise of any warrant in any manner which
interferes with the timely exercise of this Warrant.

                                       8
<PAGE>
 
     7.   No Voting or Dividend Rights; Limitation of Liability. Nothing 
          -----------------------------------------------------
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent as a shareholder in respect of meetings
of shareholders for the election of directors of the Company or any other
matters or any rights whatsoever as a shareholder of the Company. No dividends
or interest shall be payable or accrued in respect of this Warrant or the
interest represented hereby or the shares purchasable hereunder until, and only
to the extent that, this Warrant shall have been exercised. No provisions
hereof, in the absence of affirmative action by the holder to purchase shares of
Preferred Stock, and no mere enumeration herein of the rights or privileges of
the Holder hereof, shall give rise to any liability of such Holder for the Stock
Purchase Price or as a shareholder of the Company, whether such liability is
asserted by the Company or by its creditors.

     8.   Intentionally Deleted.
          ---------------------

     9.   Registration Rights.  The Holder hereof shall be entitled, with
          ------------------- 
respect to the shares of Common Stock or other securities issued upon conversion
of such Preferred Stock to the "piggyback" registration rights set forth in
section 1.3 of the Second Amended and Restated Investors Rights Agreement dated
as of June 25, 1997, as amended from time to time to the same extent and on the
same terms and conditions as possessed by the other Warrant Holders thereof.
The company shall take such action as may be reasonably necessary to assure that
the granting of such registration rights to the Holder does not violate the
provisions of such agreement or any of the Company's charter documents or rights
of prior Grantees of registration rights.

     10.  Rights and Obligations Survive Exercise of Warrant. The rights and
          --------------------------------------------------
obligations of the Company, of the Holder of this Warrant and of the holder of
shares of Preferred stock issued upon exercise of this Warrant, contained in
Sections 6, 8 and 9 shall survive the exercise of this Warrant.

     11.  Modification and Waiver.  This Warrant and any provision hereof may be
          -----------------------
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     12.  Notices.  Any notice, request or other document required or permitted
          -------
to be given or delivered to the holder hereof or the Company shall be deemed to
have been given (i) upon receipt if delivered personally or by courier (ii) upon
confirmation of receipt if by telecopy or (iii) three business days after
deposit in the US mail, with postage prepaid and certified or registered, to
each such holder at its address as shown on the books of the Company or to the

Company at the address indicated therefor in the first paragraph of this
Warrant.

     13.  Binding Effect on Successors.  This Warrant shall be binding upon any
          ----------------------------
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets.  All of the obligations of the
Company relating to the Preferred Stock issuable upon the exercise of this
Warrant shall survive the exercise and termination of this Warrant.  All of the
covenants and agreements of the Company shall inure to the benefit of the
permitted successors and assigns of the Holder hereof.  The Company will, at the
time of the exercise of this Warrant, in whole or in part, upon request of the
Holder hereof but at the Company's expense, acknowledge in writing its
continuing obligation to the Holder hereof in respect of any rights (including,
without limitation, any right to registration of the shares of Common Stock) to
which the Holder hereof shall continue to be entitled after such exercise in
accordance with this Warrant; provided, that the failure of the Holder hereof to
make any such request shall not affect the continuing obligation of the Company
to the Holder hereof in respect of such rights.

     14.  Descriptive Headings and Governing Law.  The descriptive headings of
          --------------------------------------
the several sections and paragraphs of this Warrant are inserted for convenience
only and do not constitute a part of this Warrant.  This Warrant shall be
construed and enforced in accordance with, and the rights of the parties shall
be governed by, the laws of the State of California, without regard to the
conflict of law provisions.

     15.  Lost Warrants or Stock Certificates.  The Company represents and

constitute an Event of Default:


          (A) Any "Event of Default" as defined in the Loan Agreement.

          (B) Secured Party shall not have a first perfected security interest
in any Collateral for ten (10) or more days after notice to Debtor;

all of the Collateral, including any proceeds, is in danger of dissipation,
loss, theft, damage or destruction, or otherwise in jeopardy such as would
materially impair the value of the Collateral (with due consideration to
applicable insurance coverage);

          (E) Debtor shall fail to perform any of its duties or obligations
under this Agreement not specifically referenced in this Article 6 and such
failure remains uncured for ten (10) or more days after notice to Debtor;

     6.2  ACCELERATION AND REMEDIES.  Upon the occurrence of any Event of
Default secured Party shall be entitled to, at Secured
<PAGE>
 
Party's option, without notice or demand of any kind, (a) declare all or any
part of the Indebtedness immediately due and payable; (b) exercise any or all of
the rights and remedies available to a secured party under the Uniform
Commercial Code or any other applicable law; and (c) exercise any or all of
Secured Party's rights and remedies provided for in this Agreement and in any
other Loan Document.  The obligations of Debtor under this Agreement shall
continue to be effective or be reinstated, as the case nay be, if at any time
any payment of any Indebtedness is rescinded or must otherwise be returned by
Secured Party upon, on account of, or in connection with, the insolvency,
bankruptcy or reorganization of Debtor, or otherwise, all as though such payment
had not been made.

     6.3  SALE OF COLLATERAL.  After the occurrence of an Event of Default
Secured Party may sell all or any part of the Collateral, at public or private
sales, to itself, a wholesaler, retailer or investor, for cash, upon credit or

commercially reasonable.  To the extent permitted by law, Debtor hereby
specifically waives all rights of redemption and any rights of stay or appraisal
which it has or may have under any applicable law in effect from time to time.
Any such public or private sales shall be held at such times and at such
place(s) as Secured Party may determine.  In case of the sale of all or any part
of the Collateral on credit or for future delivery, the Collateral so sold may
be retained by Secured Party until the selling price is paid by the purchaser,
but Secured Party shall not incur any liability in case of the failure of such
purchaser to pay for the Collateral and, in case of any such failure, such
Collateral may be resold.  Secured Party may, instead of exercising its power of
sale, proceed to enforce its security interest in the Collateral by seeking a
judgment or decree of a court of competent jurisdiction.

     6.4  DEBTOR'S OBLIGATION UPON DEFAULT.  Upon the request of Secured Party
after the occurrence of an Event of Default Debtor will:

          (A) Assemble and make available to Secured Party the Collateral at
such place(s) as Secured Party shall designate, segregating all Collateral so
that each item is capable of identification; and

          (B) Permit Secured Party, by Secured Party's officers, employees,
agents and representatives, to enter any premises where any Collateral is
located, to take possession of the Collateral and to remove the Collateral or to
conduct any public or private sale of the Collateral, all without any liability
of Secured Party for rent or other compensation for the use of Debtor's
premises.

                   ARTICLE 7 - SPECIAL COLLATERAL PROVISIONS
                                        
     7.1  PERFORMANCE OF DEBTOR'S OBLIGATIONS.  Without having any obligation to
do so, Secured Party may perform or pay any obligation which Debtor has agreed
to perform or pay under this Agreement, including, without limitation, the
payment or discharge of taxes or Liens levied or placed on or threatened against
the Collateral.  In so performing or paying, Secured Party shall determine the
action to be taken and the amount necessary to discharge such obligations.
Debtor shall reimburse Secured Party on demand for any amounts paid by Secured
Party pursuant to this Section, which amounts shall constitute Indebtedness
secured by the Collateral and shall bear interest from the date of demand at the
rate applicable to overdue payments under the Loan Agreement.

     7.2  POWER OF ATTORNEY.  For the purpose of protecting, preserving and
enforcing the Collateral and Secured Party's rights under this Agreement, Debtor
hereby irrevocably appoints Secured Party, with full power of substitution, as
its attorney-in-fact with full power and authority to do any act which Debtor is
obligated to do, or Secured Party has the right to do, hereunder; to exercise
such rights with respect to the Collateral as Debtor might exercise; to use such
Collateral; to enter Debtor's premises; to give notice of Secured Party's
security interest in and to collect the Collateral and the Proceeds; and to
execute and file in Debtor's name any financing statements, amendments and
continuation statements necessary or desirable to perfect or continue the
perfection of Secured Party's security interests in the Collateral.  Debtor
hereby ratifies all that Secured Party shall lawfully do or cause to be done by
virtue of this appointment.

     7.3  AUTHORIZATION FOR SECURED PARTY TO TAKE CERTAIN ACTION. The power of
attorney created in Section 7.3 is a power coupled with an interest and shall be
irrevocable.  The powers conferred on Secured Party hereunder are solely to
protect its interests in the Collateral and shall not impose any duty upon
Secured Party to exercise such powers.  Secured Party shall be accountable only
for amounts that it actually receives as a result of the exercise of such powers
and in no event shall Secured Party or any of its directors, officers,
employees, agents or representatives be responsible to Debtor for any act or
failure to act, except for gross negligence or willful misconduct.  Secured
Party may exercise this power of attorney without notice to or assent of Debtor,
in the name of Debtor, or in Secured Party's own name, from time to time in
Secured Party's sole discretion and at Debtor's expense.  To further carry out
the terms of this Agreement, Secured Party may upon the occurrence of an Event
of Default:
<PAGE>
 
          (A) Execute any statements or documents to take possession of, and
endorse and collect and receive delivery or payment of, any checks, drafts,
notes, acceptances or other instruments and documents constituting the payment
of amounts due and to become due or any performance to be rendered with respect
to the Collateral;

          (B) Sign and endorse any invoices, freight or express bills, bills of
lading, storage or warehouse receipts; drafts, certificates and statements under
any commercial or standby letter of credit, assignments, leases, bills of sale,
or any other documents relating to the Collateral, including without limitation
the Records;

          (C) Use or operate Collateral or any other property of Debtor for the
purpose of preserving or liquidating Collateral;

          (D) File any claim or take any other action or proceeding in any court
of law or equity or as otherwise deemed appropriate by Secured Party for the
purpose of collecting any and all monies due or securing any performance to be
rendered with respect to the Collateral;

          (E) Commence, prosecute or defend any suits, actions or proceedings or
as otherwise deemed appropriate by Secured Party for the purpose of protecting
or collecting the Collateral. In furtherance of this right, upon the occurrence
of an Event of Default Secured Party may apply for the appointment of a receiver
or similar official to operate Debtor's business, and, to the fullest extent
permitted by law, Debtor hereby waives any right to oppose such appointment;

          (F) Prepare, adjust, execute, deliver and receive payment under
insurance claims, and collect and receive payment of and endorse any instrument
in payment of loss or returned premiums or any other insurance refund or return,
and apply such amounts, at Secured Party's sole discretion, toward repayment of
the Indebtedness or replacement of the Collateral.

     7.4  APPLICATION OF PROCEEDS.  Any Proceeds and other monies or property
received by Secured Party pursuant to the terms of this Agreement or any Loan
Document may be applied by Secured Party first to the payment of expenses of
collection, including without limitation to reasonable attorneys' fees, and then
to the payment of the Indebtedness in such order of application as Secured Party
may elect.  Notwithstanding the rights given to Debtor pursuant to California
Civil Code sections 1479 and 2822 or equivalent provisions in the laws of the
state specified in the governing law clause of this document (and any amendments
or successors thereto), to designate how payments will be applied, Debtor hereby
waives such rights and Secured Party shall have the right in its sole discretion
to determine the order and method of
<PAGE>
 
the application of payments received from Debtor or from the sale or disposition
of the Collateral and to revise such application prospectively or retroactively
at its discretion.

     7.5  DEFICIENCY.  If the proceeds of any sale of the Collateral are
insufficient to cover all costs and expenses of such sale and the payment in
full of all Indebtedness, plus all other sums required to be expended or
distributed by Secured Party, then Debtor shall be liable for any such
deficiency.

     7.6  SECURED PARTY TRANSFER.  Upon the transfer of all or any part of the
Indebtedness, Secured Party may transfer all or any part of its interest in the
Collateral and shall be fully discharged thereafter from all liability and
responsibility with respect to such interest in the Collateral so transferred,
and the transferee shall be vested with all the rights and powers of Secured
Party hereunder with respect to such interest in the Collateral so transferred.


                         ARTICLE 8 - GENERAL PROVISIONS
                                        
     8.1  NOTICES.  Any notice given by any party under this Agreement shall be
given in the manner prescribed in the Loan Agreement.

     8.2  BINDING EFFECT.  This Agreement shall be binding upon Debtor, its
permitted successors, representatives and assigns, and shall inure to the
benefit of Secured Party and its successors, representatives and assigns;
provided however that Debtor may not assign or transfer Debtor's obligations
under this Agreement without Secured Party's prior written consent.  Secured
Party reserves the right to sell, assign, or transfer its rights and powers
under this Agreement in whole or in part without notice to Debtor.  In that
connection, Secured Party may disclose all documents and information which
Secured Party now or hereafter may have relating to this Agreement, Debtor or
Debtor's business.

     8.3  NO WAIVER.  Any waiver, consent or approval by Secured Party of any
Event of Default or breach of any provision, condition or covenant of this
Agreement or any Loan Document must be in writing and shall be effective only to
the extent set forth in writing.  No waiver or any breach of default shall be
deemed a waiver of any later breach or default of the same or any other
provision of this Agreement or any of the Loan Documents.  No failure or delay
on the part of Secured Party in exercising any power, right or privilege under
this Agreement or any Loan Document shall operate as a waiver thereof, and no
single or partial exercise of any such power, right or privilege shall preclude
