PART I

ITEM 1.   BUSINESS

          The following discussion contains forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended.  Predictions of
future events are inherently uncertain.  Actual events could differ materially
from those predicted in the forward-looking statements as a result of the risks
set forth in the following discussion and, in particular, the risks discussed
below under the caption "Risk Factors that May Affect Operating Results."

  International Network Services ("INS" or the "Company") is a worldwide
provider of services for complex enterprise networks. The Company provides
services for the full life cycle of a network, including planning, design,
implementation, operations and optimization, and maintains expertise in the most
complex network technologies and multivendor environments. Areas of expertise
include wide area networks ("WANs"), network management, network and host
security and high performance local area networks ("LANs"), and virtual LANSs
("VLANs"). The Company believes that it is able to provide unbiased assessments
and optimal solutions for its clients. The Company offers its services on a long
or short term basis in any or all phases of the network life cycle. The
Company's services are particularly well suited to clients who out-task a
portion of their information technology infrastructure. The Company has
developed an on-line solutions resource, Knowledge Network, through which the
Company's network systems engineers communicate and collaborate to provide
solutions to clients' complex enterprise network needs. The Company is
leveraging its expertise in complex networks to develop electronic services
which combine software and services to provide clients with solutions for
certain repetitive network management tasks, such as network monitoring and
network performance reporting. The Company's current electronic service,
EnterprisePRO/SM/, is designed to collect data, generate reports and compile
network information for use in the optimization of networks. The Company serves
its clients, many of which have multi-location enterprise networks, through its
network of 36 offices. As of June 30, 1998, the Company employed 1,353 persons,
including 1,053 network systems engineers and managers.


BACKGROUND

  The ability of businesses to exchange information both internally and
externally is a competitive advantage in many industries. To exchange
information, many businesses are increasingly using client/server based
applications, e-mail, remote access by mobile workers, the Internet, corporate
Intranets, video, graphics and audio. The amount of data generated by these
applications combined with the larger number of users connected to networks, has
increased traffic and placed higher demand on networks. In this environment,
companies that have the most responsive and reliable information systems
networks will have a competitive advantage.

  As network traffic has grown, the technology underlying networks has become
increasingly complex. Network hardware and software companies are rapidly
developing sophisticated new technologies such as routers, inverse multiplexers,
switches, asynchronous transfer mode ("ATM") and VLANs to accommodate the
increase in data traffic. The implementation of these technologies requires
significant expertise. In addition, the complexity of networks is magnified by
the need to integrate these new technologies with legacy network systems. As a
result, it is increasingly difficult for network managers to ensure the
reliability, performance and security of these large, heterogeneous networks.
Furthermore, the tools available to manage today's networks are themselves very
complex and require investments in hardware, software, personnel and training.

  Although companies have attempted to develop the necessary expertise, this
rapid technological change and increasing complexity have made it difficult for
companies to implement and manage their 
<PAGE>
 
large multivendor network environments. In addition, to remain competitive,
companies are increasingly focused on their core business competencies and often
turn to third-party service providers for non-core functions, such as those
related to their computing environments. While some companies "out-source" their
entire computing environment, an increasing number of companies are pursuing an
approach to more actively manage their computing environments by "selectively
out-sourcing" or "out-tasking" only a limited set of services. The rapid
technological changes in networking and the move to out-tasking have created
increased demand for third-party network services.

  To date, it has been difficult for businesses to find adequate third-party
solutions for their complex network services needs. Although there are many
suppliers of network services, few focus on services for complex multivendor
networks. For example, some computer systems and network equipment vendors
provide services; however, they focus on distributing their own products and
often lack the skills to implement solutions in multivendor environments.
Systems integrators and value added resellers ("VARs") have historically focused
on legacy computing environments and often do not have sufficient expertise in
distributed client/server network environments. Telecommunications providers are
often called upon to provide complex multivendor data network services as part
of total communication solutions; however, they often do not have adequate or
available expertise and therefore often look to other third-party service
providers for complex network services.


INS SOLUTION

  INS is a provider of services for complex enterprise networks. The Company
provides services for the full life cycle of a network, including planning,
design, implementation, operations and optimization, and maintains expertise in
the most complex network technologies and multivendor environments. The Company
believes that it is able to provide unbiased assessments and optimal solutions
for its clients. In addition, the Company provides a focused, flexible approach
to assisting clients in any or all phases of the network life cycle. The
Company's services are particularly well suited to out-tasking. The Company has
developed an on-line solutions resource, Knowledge Network, through which the
Company's network systems engineers communicate and collaborate to provide
solutions to clients' complex enterprise network needs. In addition to
professional services, the Company has developed electronic services which
combine software and services to provide clients with solutions for repetitive
network management tasks. The Company's current electronic service,
EnterprisePRO, is designed to collect data, generate reports and compile network
information for use in the optimization of networks. The Company serves its
clients, many of which have multi-location enterprise networks, through its
network of 36 offices.


STRATEGY

  The Company's objective is to become the premier provider of services for
complex enterprise networks. To achieve its objective, the Company is pursuing
the following strategies:

  Build and Strengthen Client Relationships. The Company believes that
delivering dependable, high-quality network services is critical to
strengthening its relationships with existing clients, gaining repeat business
and generating new business from referrals. The Company seeks to establish long-
term relationships with its clients by becoming an integral part of their
network operations. The Company also plans to continue to build and strengthen
relationships with hardware and software vendors, system integrators and
telecommunications providers to assist them in providing total networking
solutions to their customers.

  Expand Client Base in Existing and New Markets. The Company's strategy is to
expand its presence in the geographic markets it currently serves and to enter
new markets where it views the opportunity as attractive. The Company currently
offers its services through a network of 36 offices in the United States, Canada
and the United Kingdom. The Company believes that a broad presence will
strengthen its 
<PAGE>
 
competitive position within the network services market and enable it to better
service its clients and enter new markets worldwide.

  Attract and Retain High Quality Network Systems Engineers. The Company
believes that its network systems engineers are critical to its success. The
Company's strategy is to continue to attract and retain the most qualified
network systems engineers by providing a rich environment and culture and by
offering professional development and financial opportunities. The Company
generally recruits network systems engineers that have significant technical
expertise and offers them professional training as well as the opportunity to
accelerate their career development by working on difficult problems and
collaborating with other network systems engineers to implement sophisticated
technology in complex enterprise networks. The Company promotes its corporate
culture with stated values that encourage employees to be their best, work as a
team and continually learn. The Company intends to continue to build its
worldwide recruiting organization and to invest heavily in training and
development.

  Develop and Expand Corporate Infrastructure. The Company believes that its
corporate infrastructure provides it with a competitive advantage in delivering
services while enabling it to expand its operations. This infrastructure
includes functions, such as recruiting, training and professional development,
collaboration tools, such as Knowledge Network, and management information
systems to give management the information necessary to make timely and accurate
decisions. The Company believes that by continuing to develop and refine its
employee recruiting and training infrastructure, strengthening its operational
management reporting systems and controls, and expanding its information
resources, it will be well-positioned to deliver high quality network services
and support growth in its operations.

  Expand Electronic Services. The Company intends to leverage its expertise in
complex networks by continuing to develop electronic services and software
license fees for certain repetitive network management tasks, such as network
monitoring and network performance reporting. In addition to the potential of
revenue from services and license fees, electronic services are designed to
build and maintain client relationships and provide opportunities for additional
professional services.

  Pursue Strategic Acquisitions. The Company intends to research, and if
appropriate, pursue acquisitions some of which may include expanding within
existing markets, entering new markets, increasing the range of services, adding
industry and technical expertise, and/or acquiring technology that can be used
in electronic services.

  No assurance can be given that the Company will be able to implement its
strategy or achieve its objectives. See "Risk Factors That May Affect Operating
Results."

SERVICES

  The Company provides professional services and technology expertise for all
phases of the network life cycle and provides electronic services for routine
network management tasks.

 Professional Services

  The Company had 1,053 network systems engineers and managers engaged in
providing services for complex enterprise networks as of June 30, 1998. The
Company has both the breadth of expertise required to support the full life
cycle of a network, which includes planning, design, implementation, operations
and optimization, and the depth of expertise required to address complex and
rapidly changing technology. The Company offers its services on a long- or
short-term basis in any or all phases of the network life cycle. The Company's
services maximize flexibility in meeting customer requirements, offer added
value, and can be clearly described and presented.

  In order to meet the challenge of providing consistent, quality service, the
Company staffs each project with a complement of network systems engineers with
requisite technical and management 
<PAGE>
 
experience. The Company works with the client to create a plan that defines what
will be delivered as well as how success or completion will be measured. To
encourage quality assurance, the Company involves the service management team in
all aspects of delivery and also coordinates content and progress reviews.
Further, the Company uses Knowledge Network to bring the expertise and
experience of many talented network systems engineers to bear on an assignment.

  The Company's services are provided either as discrete projects or as part of
ongoing relationships. Project content and scope range from simple task-oriented
engineering and value-added implementation efforts to large-scale programs
involving multiple resources across several client locations. The Company
generates revenue from its professional services generally on a time and
expenses basis; however, some projects are delivered on a fixed-price basis. The
success of the Company's business will depend on the Company's ability to
fulfill the increasingly sophisticated needs of its clients. The Company's
clients are generally able to reduce or cancel their use of the Company's
services without penalty and with little or no notice. See "Risk Factors That
May Affect Operating Results -- Risks Associated with Client Concentration;
Absence of Long-Term Agreements" and "--Risks Associated With Electronic
Services."

 Network Life Cycle Services

  The Company provides services for any or all phases of the network life cycle,
which includes planning, design, implementation, operations and optimization.

  Network Planning. The network planning phase of the network life cycle focuses
on providing clients with strategic and tactical reviews of their current
network operations and future network requirements. Network planning services
encompass a number of critical planning elements:

  .  Defining client business requirements

  .  Developing strategic information architectures

  .  Performing network baseline audits

  .  Preparing capacity plans for the physical network, logical transport and
     services

  .  Selecting preferred technology

  .  Conducting network security audits and planning

  Network Design. The network design phase includes services that assist in the
design of physical, logical and operational information infrastructures. These
services involve detailing the network specifications and implementation tactics
necessary to achieve clients' business objectives. The Company generates a set
of working papers that identify the specific technologies to be used and how
these technologies will be configured and implemented. These services also take
into consideration how the new technology will integrate into the client's
existing hardware and software and how it will be managed on an ongoing basis.
Examples of services provided by the Company in the network design phase
include:

  .  Defining functional requirements

  .  Developing multivendor integration plans

  .  Preparing technical design documentation

  .  Developing engineering specifications and documents

  .  Preparing Request for Proposal specifications or other make/buy criteria
<PAGE>
 
  .  Providing detailed component purchasing lists

  Network Implementation. The network implementation phase includes high value-
added network services, such as internet protocol addressing and router
configuration, and, to a much lesser extent, traditional system integrator
functions, such as hardware installation. The Company believes it has expertise
in integrating new systems without disrupting ongoing business operations,
thereby adding value and reducing risk to clients. The Company customizes an
implementation plan for each client, which may include the following activities:

  .  Project management

  .  Integrating new hardware and software products and systems

  .  Building network operations and management centers

  .  Re-configuring and upgrading network elements, systems and facilities

  .  Implementing installation documentation, conformance testing and compliance
     certification

  Network Operations. The network operations phase includes ongoing tasks
necessary to keep the client's network fully operational. The Company has
experience in delivering operations services to a range of clients, including
those with newer client/server networks running both Internet (TCP/IP) and
workgroup (Novell and Microsoft) protocols intermingled with legacy (SNA)
networks. Specific operations activities are delivered according to individual
client requirements drawing from a well-understood set of operating practices.
Examples of these practices include:

  .  Network administration, including management of user accounts, service
     levels, and client administrative or accounting practices

  .  Network utilization analysis, involving ongoing measurement of network
     activity against established network baselines

  .  Ongoing management of documentation, including physical assets, logical
     topologies, policies and procedures

  .  Network troubleshooting, involving fault detection, isolation, repair and
     restoration

  .  Alarm management including setting of alarm levels, cross-correlation,
     problem diagnosis and dispatch of service resources

  .  Network backup, including design and supervision of backup processes and
     policies, and exercise of disaster recovery procedures

  .  Routine moves, additions, and changes to network elements, infrastructure
     and services

  Network Optimization. The network optimization phase involves maximizing the
rate of return of enterprise network investments on behalf of the client by such
methods as reducing operating costs and increasing network utilization. Although
optimization may be viewed as a separate stage of the network life cycle,
optimization is closely linked with the other phases of the network life cycle.
Optimization services can be long-term in nature, address issues such as cost
containment and utilization, and are often aimed at optimizing LAN
infrastructure. These services can also be packaged as discrete projects,
designed to present alternatives for optimization of workgroup, departmental,
building, or campus network investments. Finally, the Company can assist in
optimizing "logical" networks, wherein the Company 
<PAGE>
 
addresses a protocol, service or application operating in the larger context of
the client's enterprise network. Examples of the Company's network optimization
services include:

  .  Recommendations for efficient allocation of bandwidth

  .  Network traffic analysis, identification of bottlenecks and recommendations
     for change

  .  Network process re-engineering

  .  Knowledge transfer to client operations personnel on topics, such as basic
     practices, or operation of network management tools and stations


 Technology Expertise

  The Company has developed expertise in a number of areas, including WANs,
network management, network and host security, high performance LANs and VLANs.

  Wide Area Networks. Wide area network design and optimization has special
value in multi-protocol, multi-vendor enterprise network environments. The
Company has substantial expertise in the design and optimization of shared
transport TCP/IP and SNA networks, including emerging and legacy networking
disciplines that span more than 20 years of network technology. Subject matter
expertise includes commercial transport technologies (frame relay, ATM, T1/T3
leased lines with HDLC, SONET, SMDS, ISDN, and X.25), interior and exterior
routing protocols (IGRP, EIGRP, CIDR, BGP-4, OSPF, RIP, and RIPv2), and commonly
used network protocols ( TCP/IP, SNA, IPX, Apple, DECnet, VINES).

  Network Management. Network management practices include design and
implementation of network operations/management centers, design of distributed
network management systems, selection, installation, and integration of network
management platforms and integration with alarm managers, trouble ticket systems
and "manager of managers" tools. Subject matter expertise includes SNMP, SNMPv2,
RMON, RMON2, HPOV, Optivity, Netview 6000, SunNet Manager, Spectrum, Seagate
NerveCenter, Remedy ARS and broad-based skills in network management concepts
and functions (fault, performance, configuration, accounting, security).

  Network and Host Security. Network and host security practices include
research and documentation of security policies, selection and installation of
Internet and Intranet firewalls, secure remote access solutions, identification
and installation of various security tools, audits of server and workstation
security, and training of clients on security topics. Subject matter expertise
includes firewall design, remote access design, authentication, server, host,
and workstation industry best practices, new security protocols (S/WAN, SHTTP,
SSL), cryptography and encryption, and high performance secure platforms.

  High Performance Local Area Networks and Virtual Local Area Networks.
Consulting on design and implementation of high-performance LANs and VLANs
requires maintaining state of the art expertise on a broad array of topics. The
Company has expertise in switching technology and products, performance tuning,
ATM technology and applications, ATM migration, full-duplex LANs, and other high
speed LAN components.


 Electronic Services

  The Company has leveraged its expertise in complex networks to develop
electronic services which combine software and services to provide clients with
solutions for certain repetitive network management tasks, such as network
monitoring and network performance reporting. The Company's current offering,
EnterprisePRO, is designed to collect data, generate reports and compile network
information for use in the optimization of networks. The Company believes that

<PAGE>
 
EnterprisePRO can reduce network administration costs, improve operating
efficiencies and provide a better perspective on network performance.

  EnterprisePRO is designed to be a "turn-key" solution for network performance
reporting and analysis. Prior to the quarter ended September 30, 1997, the
Company offered its electronic services to clients only as a service under which
the Company generally received a one-time installation fee and a monthly service
fee that varied with the size of the network being monitored. The Company
currently allows clients to separately purchase a software license, software
subscription and support services as an alternative to the service contract. The
EnterprisePRO server software provides a proprietary network data collection
system and an intuitive Web-based user interface. A single server polls each
device every five minutes and can monitor up to 10,000 network interfaces. The
Web-based interface provides customizable network views that allow clients to do
network diagnosis, interactive decision support, and management information for
fact-based network architecture and upgrade planning. EnterprisePRO reports
include utilization statistics for frame relay, WAN, LAN and router CPU,
ethernet Hubs device uptime, and RMON and ROMON2 statistics, including top
transmitters and protocol distribution. The INS operations center includes
additional proprietary software. EnterprisePRO support service provides an
automatic connection to the operations center by modem and download of the data.
Operations center personnel back up the data and view generated exception
reports to do daily quality checks and provide client support. The operations
center performs updates to client configurations, troubleshooting of
EnterprisePRO servers and updates EnterprisePRO service via a software push
delivery model. EnterprisePRO installation services provide installation of the
server at the client site and a connection to the INS operations center at the
Company's headquarters. EnterprisePRO software subscription provides periodic
updates of server software.

  The Company believes that its professional services and electronic services
complement one another. The cumulative expertise of the Company's professional
services staff provides valuable information upon which electronic services may
be based. Electronic services are designed to build and maintain client
relationships and provide opportunities for additional professional services.

KNOWLEDGE NETWORK

  Knowledge Network is the Company's on-line solutions resource. Knowledge
Network combines the Company's proprietary information stored in a document
management system, a library of industry and manufacturer product information
and specifications, periodicals, databases and CDs from vendors providing
additional technical support, and a means by which the Company's network systems
engineers can communicate and collaborate in resolving clients' complex
enterprise network issues. Network problems encountered by INS network systems
engineers and the ultimate solutions are catalogued and stored on a confidential
central database for use by INS network systems engineers and management only.
INS network systems engineers are able to query the Knowledge Network for
precedents, conversation threads and other possible solutions for difficult
network issues and can send e-mail through the Knowledge Network to other INS
network systems engineers for assistance in resolving these issues. Knowledge
Network enables the Company to leverage the collective talents and experience of
network experts in the organization to provide clients with proven and cost-
effective solutions to their network services needs. The Company believes that
the Knowledge Network provides it with a competitive advantage over other
network services providers.

CLIENTS

The Company performs professional services for a variety of clients across a
broad range of industries. The Company has derived a significant portion of its
revenue from a limited number of large clients and expects this concentration to
continue. No one client accounted for more than 10% of revenue in fiscal 1997 or
1998.  In fiscal 1996, a client accounted for approximately $7.5 million, or
17.0%, of the Company's revenue. See "Risk Factors That May Affect Operating
Results--Risks Associated with Client Concentration; Absence of Long-Term
Agreements."
<PAGE>
 
SALES AND MARKETING

  The Company employs account managers who identify and sell to clients and
manage client relationships. Many members of the Company's account management
team have significant experience selling complex network and computer products
and services. The Company also has a marketing group which provides sales
support materials and marketing communications. Account managers generally
identify clients through direct marketing and referrals. The Company employs a
team selling approach, whereby account managers collaborate with field and
technical managers and network systems engineers to assess potential projects
and communicate the specific expertise of the Company's consultants to potential
clients. In addition to other marketing strategies, the Company believes that
delivering dependable, high-quality services is critical to strengthening its
relationships with existing clients, gaining repeat business and generating new
business from referrals. The Company seeks to establish long-term relationships
with its clients by becoming an integral part of their network operations.

  The Company markets its professional services directly to large end-user
clients who have chosen to out-task network services, and indirectly through
third parties, including large telecommunications carriers, systems integrators,
hardware and software vendors, and VARs.  In addition, the Company has developed
a significant relationship with Cisco Systems, Inc., ("Cisco") pursuant to which
the Company has entered into direct relationships with clients as a result of
referrals from Cisco and provides services directly to Cisco, primarily as a
subcontractor.  The Company believes that maintaining and enhancing its
relationship with Cisco is important to the Company's business due to Cisco's
leading position in the large scale, enterprise internetworking market. Cisco
develops, manufactures, markets and supports high-performance, multiprotocol
internetworking systems that link geographically dispersed LANs and WANs.
Although the Company believes that its relationship with Cisco is good, there
can be no assurance that the Company will be able to maintain or enhance its
relationship with Cisco. Any deterioration in the Company's relationship with
Cisco could have a material adverse effect on the Company's business, operating
results and financial condition. Furthermore, although the Company has a
relationship with Cisco, the Company is an independent provider of network
services and seeks to provide the best solution for its clients regardless of
network platform or vendor. Therefore, should the Company's relationship with
Cisco be perceived as compromising the Company's ability to provide unbiased
solutions, the Company's relationship with existing or potential clients could
be materially adversely affected.

  The Company's current electronic service, EnterprisePRO, is marketed through
the Company's account managers and through resellers and OEMs. EnterprisePRO
resellers will identify potential clients and negotiate the services contracts
and are responsible for installation and first level support of the client
installation. The Company provides the back office automation and service to the
client.  The success of these contracts will depend in part on the level of
commitment and effort of these resellers. Electronic services may be sold under
the Company's name or under a private label of the reseller.  

  The Company's clients are generally able to reduce or cancel their use of the
Company's services without penalty and with little or no notice. As a result,
the Company believes that the number and size of its existing projects are not
reliable indicators or measures of future revenue. The Company has in the past
provided, and is likely in the future to provide, services to clients without a
written commitment or contract. When a client defers, modifies or cancels a
project, the Company must be able to rapidly redeploy network systems engineers
to other projects in order to minimize the underutilization of employees and the
resulting adverse impact on operating results. In addition, the Company's
operating expenses are relatively fixed and cannot be reduced on short notice to
compensate for unanticipated variations in the number or size of projects in
progress. As a result, any termination, significant reduction or modification of
its business relationships with any of its significant clients or with a number
of smaller clients could have a material adverse effect on the Company's
business, operating results and financial condition.
<PAGE>
 
  The Company's future success will also depend in large part on the development
of new business by the Company's account managers, who solicit new business and
manage relationships with existing clients. As a result, the Company's success
will depend on its ability to attract and retain qualified account managers who
have an understanding of the Company's business and the industry it serves.
Competition for account managers is intense and the Company has experienced, and
may in the future experience high rates of turnover among its account managers.
In addition, integration of new account managers into the Company's business can
be lengthy. Any inability of the Company to attract and retain a sufficient
number of account managers or to integrate new account managers into the
Company's operations on a timely basis, would impair the Company's ability to
obtain projects from new and existing clients which could have a material
adverse effect on the Company's business, operating results and financial
condition.


HUMAN RESOURCES

  The Company believes that its success in recruiting and retaining experienced,
highly-qualified and highly-motivated personnel will depend in part on its
ability to provide a rich environment and culture and to offer professional
development and financial opportunities. As of June 30, 1998, the Company
employed 1,353 persons, including 1,053 network systems engineers and managers.

  Recruiting. The success of the Company is dependent in part on attracting and
retaining talented, creative and motivated personnel at all levels. The Company
dedicates significant resources to its recruiting efforts. The Company generally
seeks to meet its hiring needs through referrals from existing INS employees,
through a nationwide network of recruiters and through the college graduate
program. The Company's network systems engineers together have expertise in a
wide array of computer and network systems of the Company's clients and a broad
understanding of the industries in which the Company's clients are involved.

  Corporate Culture. The Company believes that developing a rich environment and
culture is critical to its success in achieving its mission of becoming the
premier provider of services for complex enterprise networks. The Company
actively fosters a set of basic values, which were developed by its employees.
These values include a dedication to being the best, respecting others and
working as a team, continuous learning and development, trustworthiness and
empowerment. The Company encourages employees to use these values in daily
decision making and balance the interests of clients, shareholders and employees
to maximize long-term Company value. The Company believes that its growth and
success are attributable in large part to its high-caliber employees and the
Company's adherence to these values.

  Professional Development. Professional development includes career
opportunities and on-the-job challenges, as well as training programs. The
Company has two career tracks for consultants, a technical track and a
management track. The Company has established a training program, which includes
national and local consultative approach workshops, collaboration workshops, new
management training and technical training. In support of its curriculum, the
Company offers advanced training through on-site simulation labs and numerous
computer-based training modules. In addition, Knowledge Network serves as an
additional training and information resource. The Company's personnel keep
apprised of technological advances and developments through a combination of on-
the-job exposure to relevant technology, special training programs, peer review
and discussions, and supervision by seasoned technical personnel.

  Compensation. The Company believes that by linking employee compensation to
the success of the Company through its incentive compensation programs, the
Company encourages an owner attitude, which the Company believes results in
decisions that maximize the Company's value and employee retention. The
Company's compensation package consists of a combination of salary, performance-
based incentive compensation, stock options and benefit plans.
<PAGE>
 
  The Company's success will depend in part on the continued services of its key
employees. The Company does not have employment or non-competition agreements
with any of its key or other employees. The loss of services of one or more of
the Company's key employees could have a material adverse effect on the
Company's business, operating results and financial condition. In addition, if
one or more key employees joins a competitor or forms a competing company, the
loss of such employees and any resulting loss of existing or potential clients
to any such competitor could have a material adverse effect on the Company's
business, operating results and financial condition. In the event of the loss of
any such employee, there can be no assurance that the Company would be able to
prevent the unauthorized disclosure, or use, of the Company's, or its clients'
technical knowledge, practice or procedures by such personnel, or that such
disclosure, or use, would not have a material adverse effect on the Company's
business, operating results and financial condition.

  The Company's future success will depend in large part on its ability to hire,
train and retain network systems engineers who together have expertise in a wide
array of network and computer systems and a broad understanding of the
industries the Company serves. Competition for network systems engineers is
intense, and there can be no assurance that the Company will be successful in
attracting and retaining such personnel. In particular, competition is intense
for the limited number of qualified managers and senior network systems
engineers. The Company has experienced, and may in the future experience high
rates of turnover among its network systems engineers. Any inability of the
Company to hire, train and retain a sufficient number of qualified network
systems engineers could impair the Company's ability to adequately manage and
complete its existing projects or to obtain new projects, which, in turn, could
have a material adverse effect on the Company's business, operating results and
financial condition. The Company has experienced, and may in the future,
experience increasing compensation costs for its network systems engineers. Any
inability of the Company to recover increases in compensation of network systems
engineers through higher billing rates or to reduce other expenses to offset
such increases, could have a material adverse effect on the Company's business,
operating results and financial condition. In addition, any inability of the
Company to attract and retain a sufficient number of qualified network systems
engineers in the future could impair the Company's planned expansion of its
business.


COMPETITION

  The network industry is comprised of a large number of participants and is
subject to rapid change and intense competition. With respect to professional
services, the Company faces competition from system integrators, value added
resellers ("VARs"), local and regional network services firms,
telecommunications providers, network equipment vendors, and computer systems
vendors, many of which have significantly greater financial, technical and
marketing resources and greater name recognition, and generate greater service
revenue than does the Company. With respect to electronic services, the Company
also faces competition from software vendors. The Company has faced, and expects
to continue to face, additional competition from new entrants into its markets.
Increased competition could result in price reductions, fewer client projects,
underutilization of employees, reduced operating margins and loss of market
share, any of which could materially adversely affect the Company's business,
operating results and financial condition. There can be no assurance that the
Company will be able to compete successfully against current or future
competitors. The failure of the Company to compete successfully would have a
material adverse effect on the Company's business, operating results and
financial condition.

  In addition, most of the Company's clients have internal network support
services capabilities and could choose to satisfy their needs through internal
resources rather than through outside service providers. As a result, the
decision by the Company's clients or potential clients to perform network
services internally could have a material adverse effect on the Company's
business, operating results and financial condition.
<PAGE>
 
  The Company believes that the principal competitive factors in the market in
which it competes include the nature of the services offered, quality of
service, client responsiveness, marketing, management, corporate culture, client
relationships, knowledge base, infrastructure and price. The Company believes it
competes favorably with respect to these factors. The Company believes that its
focus, depth and breadth of expertise and experience, infrastructure and
management distinguish it from its competitors.

INTELLECTUAL PROPERTY

  The Company's success is dependent in part on its information technology, some
of which is proprietary to the Company, and other intellectual property rights.
The Company relies on a combination of nondisclosure and other contractual
arrangements, technical measures, and trade secret and trademark laws to protect
its proprietary rights. The Company has one patent application pending and
holds one registered trademark. The Company enters into confidentiality
agreements with its employees and attempts to limit access to and distribution
of proprietary information. There can be no assurance that the steps taken by
the Company in this regard will be adequate to deter misappropriation of
proprietary information or that the Company will be able to detect unauthorized
use or take appropriate steps to enforce intellectual property rights. The
Company has in the past entered into services contracts with clients that assign
rights to certain aspects of the work performed under such contracts to such
clients. The Company does not believe that such contracts will limit the
Company's ability to render its services to other clients. However, there can be
no assurance that the Company will not receive communications in the future from
third parties or clients asserting that the Company has infringed or
misappropriated the proprietary rights of such parties. Any such claims, with or
without merit, could be time consuming, result in costly litigation and
diversion of technical and management personnel or require the Company to
develop non-infringing technology or enter into royalty or licensing agreements.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all. In the event of a successful claim of
infringement or misappropriation against the Company and failure or inability of
the Company to develop non-infringing technology or license the infringed,
misappropriated, or similar technology, the Company's business, operating
results and financial condition could be materially adversely affected.

RISK FACTORS THAT MAY AFFECT OPERATING RESULTS

  The following risk factors could materially and adversely affect the Company's
future operating results and could cause actual events to differ materially from
those predicted in the Company's forward-looking statements related to its
business.


  Variability of Quarterly Operating Results. Substantially all of the Company's
revenue is derived from professional services, which are generally provided on a
"time and expenses" basis. Professional services revenue is recognized only when
network systems engineers are engaged on client projects. In addition, a
majority of the Company's operating expenses, particularly personnel and related
costs, depreciation and rent, are relatively fixed in advance of any particular
quarter. As a result, any underutilization of network systems engineers may
cause significant variations in operating results in any particular quarter and
could result in losses for such quarter. Factors which could cause such
underutilization include: the reduction in size, delay in commencement,
interruption or termination of one or more significant projects; the completion
during a quarter of one or more significant projects; the inability to obtain
new projects; the overestimation of resources required to complete new or
ongoing projects; and the timing and extent of training, weather related shut-
downs, vacation days and holidays. The Company's revenue and earnings may also
fluctuate from quarter to quarter based on a variety of factors including the
loss of key employees, an inability to hire and retain sufficient numbers of
network systems engineers and account managers, reductions in billing rates,
write-offs of billings, or services performed at no charge as a result of the
Company's failure to meet its clients' expectations, claims by the Company's
clients for the actions of the Company's employees arising from damages to
clients' business or 
<PAGE>
 
otherwise, competition, timing of employment taxes, the development and
introduction of new services, decrease or slowdown in the growth of the
networking industry as a whole and general economic conditions. The Company's
operating results may also fluctuate based upon the ongoing market acceptance
and the timing and size of orders for electronic services (see "Risks Associated
with Electronic Services") which are difficult to forecast. If an unanticipated
order shortfall for electronic services occurs, the Company's operating results
could be materially adversely affected, particularly because margins are higher
on electronic services than professional services. In addition, the Company
plans to continue to expand its operations based on sales forecasts by hiring
additional network systems engineers, account managers and other employees, and
adding new offices, systems and other infrastructure. The resulting increase in
operating expenses would have a material adverse effect on the Company's
operating results if revenue were not to increase to support such expenses.
Based upon all of the foregoing, the Company believes that quarterly revenue and
operating results are likely to vary significantly in the future and that 
period-to-period comparisons of its operating results are not necessarily
meaningful and should not be relied on as indications of future performance.
Furthermore, it is likely that in some future quarter the Company's revenue or
operating results will be below the expectations of public market analysts or
investors. In such event, the price of the Company's common stock would likely
be materially adversely affected.

    Risks Associated with Client Concentration; Absence of Long-Term Agreements.
The Company has derived a significant portion of its revenue from a limited
number of large clients and expects this concentration to continue. No one
client, however, accounted for more than 10% of the Company's revenue for the
year ended June 30, 1998. There can be no assurance that revenue from clients
that have accounted for significant revenue in past periods, individually or as
a group, will continue, or if continued will reach or exceed historical levels
in any future period. The Company has, in the past, experienced declines in
revenue from clients that have accounted for significant revenue. In addition,
the Company generally does not have a long-term services contract with any of
its clients. The Company's clients are generally able to reduce or cancel their
use of the Company's professional services without penalty and with little or no
notice. As a result, the Company believes that the number and size of its
existing projects are not reliable indicators or measures of future revenue.
When a client defers, modifies or cancels a project, the Company must be able to
rapidly redeploy network systems engineers to other projects in order to
minimize the underutilization of employees and the resulting adverse impact on
operating results. In addition, the Company's operating expenses are relatively
fixed and cannot be reduced on short notice to compensate for unanticipated
variations in the number or size of projects in progress. As a result, any
significant reduction in the scope of the work performed for any significant
client or a number of smaller clients, the failure of anticipated projects to
materialize, or deferrals, modifications or cancellations of ongoing projects by
any of these clients could have a material adverse effect on the Company's
business, operating results and financial condition.

    Need to Attract and Retain Qualified Network Systems Engineers. The
Company's future success will depend in large part on its ability to hire, train
and retain network systems engineers who together have expertise in a wide array
of network and computer systems and a broad understanding of the industries the
Company serves. Competition for network systems engineers is intense, and there
can be no assurance that the Company will be successful in attracting and
retaining such personnel. In particular, competition is intense for the limited
number of qualified managers and senior network systems engineers. The Company
has experienced, and may in the future experience high rates of turnover among
its network systems engineers. Any inability of the Company to hire, train and
retain a sufficient number of qualified network systems engineers could impair
the Company's ability to adequately manage and complete its existing projects or
to obtain new projects, which, in turn, could have a material adverse effect on
the Company's business, operating results and financial condition. The Company
has experienced, and may in the future, experience increasing compensation costs
for its network systems engineers. Any inability of the Company to recover
increases in compensation of network systems engineers through higher billing
rates or to reduce other expenses to offset such increases, could have a
material adverse effect on the Company's business, operating results and
financial condition. In addition, any inability of the Company to attract and
retain a 
<PAGE>
 
sufficient number of qualified network systems engineers in the future could
impair the Company's planned expansion of its business.

    Dependence on New Business Development. The Company's future success will
also depend in large part on the development of new business by the Company's
account managers, who solicit new business and manage relationships with
existing clients. As a result, the Company's success will depend on its ability
to attract and retain qualified account managers who have an understanding of
the Company's business and the industry it serves. Competition for account
managers is intense and the Company has experienced, and may in the future
experience high rates of turnover among its account managers. In addition,
integration of new account managers into the Company's business can be lengthy.
Any inability of the Company to attract and retain a sufficient number of
account managers or to integrate new account managers into the Company's
operations on a timely basis, would impair the Company's ability to obtain
projects from new and existing clients which could have a material adverse
effect on the Company's business, operating results and financial condition.

    Risks Associated with Electronic Services. The Company's long-term strategy
is to derive a significant portion of its revenue from electronic services. The
Company has expended, and expects to continue to expend, substantial amounts in
the development and marketing of its electronic services. The introduction of
EnterprisePRO and any other electronic services that the Company may develop in
the future will be subject to risks generally associated with new service
introductions, including delays in development, testing or introduction, or the
failure to satisfy clients' requirements.

    Management of Growth. The Company has recently experienced a period of rapid
revenue and client growth and an increase in the number of its employees and
offices and in the scope of its supporting infrastructure. The Company does not
believe this rate of growth is sustainable. This growth has resulted in new and
increased responsibilities for management personnel and has placed and continues
to place a significant strain on the Company's management and operating and
financial systems. The Company will be required to continue to hire management
personnel and improve its systems on a timely basis and in such a manner as is
necessary to accommodate any increase in the number of transactions and clients,
any increase in the size of the Company's operations and any introduction of new
products and services. There can be no assurance that the Company's management
or systems will be adequate to support the Company's existing or future
operations. Any failure to implement and improve the Company's systems or to
hire and retain the appropriate personnel to manage its operations would have a
material adverse effect on the Company's business, operating results and
financial condition.

    Intense Competition. The network industry is comprised of a large number of
participants and is subject to rapid change and intense competition. With
respect to professional services, the Company faces competition from system
integrators, VARs, local and regional network services firms, telecommunications
providers, network equipment vendors, and computer systems vendors, many of
which have significantly greater financial, technical and marketing resources
and greater name recognition, and generate greater service revenue than does the
Company. With respect to electronic services, the Company also faces competition
from software vendors. The Company has faced, and expects to continue to face,
additional competition from new entrants into its markets. Increased competition
could result in price reductions, fewer client projects, underutilization of
employees, reduced operating margins and loss of market share, any of which
could materially adversely affect the Company's business, operating results and
financial condition. There can be no assurance that the Company will be able to
compete successfully against current or future competitors. The failure of the
Company to compete successfully would have a material adverse effect on the
Company's business, operating results and financial condition.

    Risks Associated With Potential Acquisitions. As part of its business
strategy, the Company may make acquisitions of, or significant investments in,
complementary companies, products or technologies. Any such future transactions
would be accompanied by the risks commonly encountered in making acquisitions of
companies, products and technologies. Such risks include, among others, the
difficulty 
<PAGE>
 
associated with assimilating the personnel and operations of acquired companies,
the potential disruption of the Company's ongoing business, the distraction of
management and other resources, the inability of management to maximize the
financial and strategic position of the Company through the successful
integration of acquired personnel, technology and rights, the maintenance of
uniform standards, controls, procedures and policies, and the impairment of
relationships with employees and clients as a result of the integration of new
management personnel. There can be no assurance that the Company will be
successful in overcoming these risks or any other problems encountered in
connection with any such acquisitions.

    Risks Associated With Potential International Expansion. A component of the
Company's long-term strategy is to expand into international markets. The
Company provides professional services to certain of its United States clients
in foreign locations.  The Company has opened an office in the United Kingdom to
serve its clients in Europe and an office in Toronto to serve its clients in
Canada. To date, revenue generated from international operations has not been
significant. There is no assurance that the revenue generated from international
operations will be adequate to offset the expense of establishing and
maintaining these foreign operations, and if revenue does not materialize as
anticipated, the Company's business, operating results and financial condition
could be materially adversely affected. There can be no assurance that the
Company will be able to successfully market, sell and deliver its services in
international markets. In addition to the uncertainty as to the Company's
ability to expand into international markets, there are certain risks inherent
in conducting business on an international level, such as unexpected changes in
regulatory requirements, export restrictions, tariffs and other trade barriers,
difficulties in staffing and managing foreign operations, 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 during the summer months in Europe and certain other parts of the
world, and potentially adverse tax consequences, any of which could adversely
impact the success of the Company's international operations. There can be no
assurance that one or more of these factors will not have a material adverse
effect on the Company's future international operations and,  consequently, on
the Company's business, operating results and financial condition. There can be
no assurance that the Company will be able to  compete effectively in these
markets.


    Relationship with Cisco Systems. Although the Company is a vendor
independent provider of network services, the Company has a significant
relationship with Cisco and believes that maintaining and enhancing this
relationship is important to the Company's business due to Cisco's leading
position in the large scale enterprise internetworking market. Cisco develops,
manufactures, markets and supports high-performance, multiprotocol
internetworking systems that link geographically dispersed LANs and WANs. The
Company has entered into direct relationships with clients as a result of
referrals from Cisco and provides services directly to Cisco, primarily as a
subcontractor. In addition, during the quarter ended December 31, 1997, the
Company entered into a resale agreement with Cisco, whereby Cisco's sales
organization will market EnterprisePRO to its customers and INS will deliver and
administer the service. In addition, Cisco is a shareholder of the Company and
an officer of Cisco is a member of the Company's Board of Directors. Although
the Company believes that its relationship with Cisco is good, there can be no
assurance that the Company will be able to maintain or enhance its relationship
with Cisco. Any deterioration in the Company's relationship with Cisco could
have a material adverse effect on the Company's business, operating results and
financial condition. In addition, should the Company's relationship with Cisco
be perceived as compromising the Company's ability to provide unbiased
solutions, the Company's relationship with existing or potential clients could
be materially adversely affected.


     Year 2000.  The year 2000 problem is the result of computer programs being
written using two digits rather than four to define the applicable year.
Computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a major
system failure or miscalculations. The year 2000 issue creates risk for the
Company from unforeseen problems in its own computer systems and from third
parties. Failure of the Company's and/or third 
<PAGE>
 
parties' computer systems could have a material adverse impact on the Company's
ability to conduct its business. The Company is currently reviewing its
products, its internal computer systems and systems of third parties on which
the Company relies for handling the year 2000. Based on information available to
date, the Company believes that it will be able to complete its year 2000
compliance review and make any necessary modifications to its products and
internal systems prior to the end of 1999. The Company further believes that
such review and modification, if any, will not require the Company to incur any
material charge to operating expenses over the next several years. The Company
is also seeking confirmation from third parties that their systems are year 2000
compliant or that plans are being developed to address the year 2000 problem.
However, there can be no assurance that such third-party systems will be year
2000 compliant or that the failure of such systems to be year 2000 compliant
would not have a material adverse effect on the Company's financial position or
results of operations. The Company believes its current electronic service
offering, EnterprisePro, is year 2000 compliant.


ITEM 2.   PROPERTIES

  The Company's principal administrative, sales, marketing and service
development facilities are located in approximately 47,000 square feet in two
buildings in Sunnyvale, California pursuant to leases which expire in 2001 and
2005. In addition, the Company leases field support offices in 36 cities. The
field offices range from small executive offices to a 7,000 square foot
facility. Lease terms range from month-to-month on certain executive offices to
five years on certain direct leases.  Because the Company's professional
services are generally performed at the client site, field facilities are
generally small. Field facilities are generally used for periodic meetings,
training and administration and by account managers. The Company has field
facilities in Atlanta, Georgia; Austin, Texas; Boston, Massachusetts;
Burlington, Massachusetts; Charlotte, North Carolina; Chicago, Illinois;
Cleveland, Ohio; Columbus, Ohio; Costa Mesa, California; Dallas, Texas; Denver,
Colorado; Detroit, Michigan; Ft. Lauderdale, Florida; Hartford, Connecticut;
Houston, Texas; Iselin, New Jersey; Jacksonville, Florida; Kansas City, Kansas;
Los Angeles, California; Minneapolis, Minnesota; New York, New York; Parsippany,
New Jersey; Philadelphia, Pennsylvania; Phoenix, Arizona; Quincy, Massachusetts;
Raleigh, North Carolina; Sacramento, California; San Antonio, Texas; San Diego,
California; San Mateo, California; San Ramon, California; Seattle, Washington;
Tampa, Florida; Tulsa, Oklahoma; Washington, D.C., and Woodland Hills,
California.  The Company is continually evaluating the adequacy of existing
facilities and facilities in new cities and believes that suitable additional
space will be available in the future on commercially reasonable terms as
needed.

          C. Commencement Date Memorandum. When the actual Commencement Date is
             ----------------------------                                      
determined, the parties shall execute a Commencement Date Memorandum setting

Such early entry shall be at Tenant's sole risk and shall be subject to all the
terms and provisions of this Lease, except for the payment of Rent, which shall
commence on the Commencement Date with respect to the Premises at 328 Gibraltar
Drive and on the date (the "Second Occupancy Date") which is sixty (60) days
from the date that Landlord delivers possession of the Premises at 330 Gibraltar
Drive to Tenant with respect to such portion of the Premises. In no event,
however, will the Second Occupancy Date be earlier than April 1, 1998. Landlord
shall have the right to impose such additional conditions on Tenant's early
entry as Landlord reasonably shall deem appropriate and shall have the right to
require that Tenant execute an early entry agreement containing such conditions
prior to Tenant's early entry.

             (ii)  Landlord anticipates that Landlord will be able to deliver 
possession of the Premises at 328 Gibraltar Drive to Tenant on or about January

Tenant agrees that if Landlord, for any reason whatsoever, is unable to deliver
possession of the Premises at 328 Gibraltar Drive by January 1, 1998 or if
Landlord is unable to deliver possession of the Premises at 330 Gibraltar Drive
by February 1, 1998.  Landlord shall not be liable to Tenant for any loss or
damage therefrom, nor shall this Lease be void or voidable. If, however.
Landlord is unable to deliver possession of the Premises at 328 Gibraltar Drive
to Tenant by April 1. 1998, Tenant shall have the right to terminate this Lease
with respect to the entire Premises by delivery of written notice to Landlord no

at 330 Gibraltar Drive by delivery of written notice to Landlord no later than
March 11, 1999. If Tenant elects to terminate this Lease with respect to the
entire Premises or the Premises at 330 Gibraltar Drive as permitted herein,

termination with respect to the Premises at 330 Gibraltar Drive only, that
portion of the Security Deposit allocable to such portion of the Premises, and
any prepaid Rent allocable to the Premises at 328 Gibraltar Drive and/or 330
Gibraltar Drive, as applicable.

             (iii)  If Tenant subleases all or any portion of the Premises at 
330 Gibraltar Drive to ActionTec Electronics, Inc., the tenant currently
occupying 330 Gibraltar Drive, then Tenant shall be deemed to have accepted
possession of such portion of the Premises as of February 1, 1998 subject to
ActionTec's occupancy, April 1, 1998 shall be deemed to be the Second Occupancy
Date, and Tenant shall commence paying Rent for the Premises at 330 Gibraltar

          E. Optional Tenant. Provided that Tenant is not in default hereunder,
             ---------------                                                   
either at the time of exercise or at the time the Optional Term commences,
Tenant shall have the option to extend the initial Term of approximately seven
years for one additional period of five years ("Optional Term ') on the same
terms, covenants and conditions provided herein, except that upon such renewal
the Monthly Rent due hereunder shall be the then fair market rental value of the
Premises, determined as provided in Section 5(E). Tenant shall exercise its

eighty (180) days but not more than two hundred seventy (270) days prior to the

             -------                                                          
Landlord, in lawful money of the United States, for each calendar month of the
Term, net Monthly Rent in accordance with the schedule set forth in Section

* For purposes of this schedule of Monthly Rent, the references to months 24
  through 84 of the Term shall mean the number of months from the Second 
  Occupancy Date.


          C. Additional Rent. All monies required to be paid by Tenant under
             ---------------                                                
this Lease, including without limitation Real Property Taxes pursuant to Section
15, Operating Expenses pursuant to Section 17, and insurance premiums pursuant
to Section 21, shall be deemed Additional Rent.

          D. Prorations. If the Commencement Date or the Second Occupancy Date
             ----------                                                       
is not the first day of a month, or if the termination date of this Lease is not
the last day of a month, a prorated installment of Monthly Rent based on a 30
day month shall be paid for the fractional month during which the Lease
commences or terminates.

          E. Optional Term Monthly Rent. The Monthly Rent for the Optional Term
             --------------------------                                        
shall be determined as follows:

             (i)  The parties shall have 15 days after Landlord receives the 
Option Notice within which to agree on the initial Monthly Rent for the Optional
Term based upon the then fair market rental value of the Premises as defined in
Section 5(E)(ii). If the parties agree on the initial Monthly Rent for the
Optional Term within 15 days, they shall immediately execute an amendment to
this Lease stating the initial Monthly Rent for the Optional Term and the
adjustments thereto determined in accordance with Section 5(E)(iv) below. If the
parties are unable to agree on the initial Monthly Rent for the Optional Term
within 15 days, then, the initial Monthly Rent for the Optional Term shall be
the then current fair market rental value of the Premises as determined in
accordance with Section 5(E)(iii).

             (ii)  The  "then fair market rental value of the Premises" shall be
defined to mean the fair market rental value of the Premises as of the
commencement of the Optional Term,
<PAGE>
 
taking into consideration the uses permitted under this Lease, the quality,
size, design and location of the Premises, and the rent for comparable buildings
located in Sunnyvale. In no event shall the fair market monthly rental value of
the Premises for the Optional Term be less than the Monthly Rent last payable
under the Lease.

             (iii)  Within seven days after the expiration of the 5-day period
set forth in Section 5(E)(1), each party, at its cost and by giving notice to
the other party, shall appoint a real estate appraiser with at least five years'
full-time commercial appraisal experience in the area in which the Premises are
located to appraise and set the initial Monthly Rent for the Optional Term. If a
party, does not appoint an appraiser within 10 days after the other party has
given notice of the name of its appraiser, the single appraiser appointed shall
be the sole appraiser and shall set the Monthly Rent. If the two appraisers are
appointed by the parties as stated in this Section, they shall meet promptly and
attempt to set the initial Monthly Rent. If they are unable to agree within 30
days after the second appraiser has been appointed, they shall attempt to elect
a third appraiser meeting the qualifications stated in this Section within 10
days after the last day the two appraisers are given to set the initial Monthly
Rent. If they are unable to agree on the third appraiser, either of the parties
to this Lease, by giving 10 days' notice to the other party, can apply to the
then Presiding Judge of the Santa Clara County Superior Court, for the selection
of a third appraiser who meets the qualifications stated in this paragraph. Each
of the parties shall bear one-half of the cost of appointing the third appraiser
and of paying the third appraiser's fee. The third appraiser, however selected,
shall be a person who has not previously acted in any capacity for either party.

             Within 30 days after the selection of the third appraiser, a 
majority of the appraisers shall set the initial Monthly Rent. If a majority of
the appraisers are unable to set the initial Monthly Rent within the stipulated
period of time, the three appraisals shall be added together and their total
divided by three; the resulting quotient shall be the initial Monthly Rent for
the Optional Term. If, however, the low appraisal and/or the high appraisal
are/is more than ten percent (10%) lower and/or higher than the middle
appraisal, the low appraisal and/or the high appraisal shall be disregarded. If
only one appraisal is disregarded, the remaining two appraisals shall be added
together and their total divided by two; the resulting quotient shall be the
initial Monthly Rent for the Optional Term. If both the low appraisal and the
high appraisal are disregarded as stated in this paragraph, then only the middle
appraisal shall be used as the result of the appraisal. After the initial
Monthly Rent has been set, the appraisers shall immediately notify the parties
and the parties shall amend this Lease to set forth such amount.

             (iv)  The Monthly Rent due during the Optional Term shall be 
increased every 12 months during the Optional Term by amount equal to five
percent (5%) of the Monthly Rent due for the prior 12 months of the Optional
Term.

     6.   LATE PAYMENT CHARGES

          Tenant acknowledges that late payment by Tenant to Landlord of Rent
and other charges provided for under this Lease would 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) business days after the date such Rent or other charge is due, Tenant shall
pay to Landlord an
<PAGE>
 
Additional sum equal to five percent (5%) of the amount overdue as a late
charge. This late charge shall be in addition to interest on the overdue payment
charged from the date due to the date paid at the Interest Rate. The parties
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


          Upon execution of this Lease, Tenant shall deposit with Landlord the
amount specified in the Lease Summary as Tenant's security deposit for the
faithful performance of all terms, covenants and conditions of this Lease (the
"Deposit"). Without waiving any of Landlord's other rights and remedies under
this Lease, if Tenant defaults with respect to any provision of this Lease,
Landlord may apply all or any part of the Deposit for the payment of any Rent or
other sum in default, the repair of any damage to the Premises caused by Tenant
or the payment of any other amount which Landlord may spend or become obligated
to spend by reason of Tenants 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. Tenant hereby waives any restriction on the use or
application of the Security Deposit by Landlord as set forth in California Civil
Code Section 1950.7. If Landlord so applies the Deposit, Tenant shall within ten
days after demand from Landlord restore the Deposit to the full amount set forth
in the Lease Summary. Failure of Tenant to do so shall be default under this
Lease.  Landlord's application of the Deposit shall in no event be construed as
in any way limiting Tenant's liability or obligation with respect to any such
default. If Tenant has kept and performed all terms, covenants and conditions of
this Lease, Landlord will, within thirty (30) days following termination of this
Lease, return the Deposit to Tenant or the last permitted assignee of Tenant's
interest hereunder. Landlord shall not be required to keep the Deposit separate
from its general funds, and Tenant shall not be entitled to interest on the
Deposit. No trust or fiduciary relationship is created by this Lease between
Landlord and Tenant with respect to the Deposit.

     8.   HOLDING OVER

          If Tenant remains in possession of all or any part of the Premises
after the expiration of the Term, 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 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 in this Lease. If Tenant fails to surrender the Premises upon the
expiration of the Term despite demand to do so by Landlord, Tenant shall
indemnify and hold Landlord harmless from all loss or liability, including
without limitation any claim made by a succeeding tenant, resulting from
Tenant's failure to surrender. Landlord also may pursue any remedies available
to it as a result of Tenant's holdover, either under this Lease, at law or in
equity.

Tenant shall be and become the property of Landlord upon the expiration or
sooner termination of this Lease, provided, however, that if Landlord indicated
at the time of its consent to such Alterations that Tenant would be required to
remove such Alterations at the expiration of the Term, then Tenant shall, at
Tenant's expense, remove any such Alterations so designated by Landlord and
return the Premises to their condition as of the Commencement Date, normal wear

record a Notice of Nonresponsibility or similar notice. If the Tenant
Improvements or any Alteration of the Premises by Tenant results, or in
Landlord's reasonable opinion may result, in labor disruptions, then all such
work shall be halted immediately by Tenant until such time as construction can
proceed without such disruption.

liability or expense (including attorneys' fees and costs) resulting from delay
by Tenant in so surrendering the Premises.

          Normal wear and tear, for the purposes of this Lease shall be
construed to mean wear and tear caused to the Premises by a natural aging
process which occurs in spite of application of commercially reasonable
standards for maintenance, repair and janitorial practices. It is not intended,
nor shall it be construed, to include items of neglected or deferred maintenance
which would have or should have been attended to during, the Term if
commercially reasonable standards had been applied to properly maintain and keep
the Premises at all times in good condition and repair.

     15.  REAL PROPERTY TAXES

          A. Payment by Tenant. On or before April 1 and December 1 of each
             -----------------                                             
calendar year during the Term, Tenant shall pay to Landlord, as Additional Rent,
all Real Property Taxes as set forth on the county assessor's tax statement for
the Premises and the Land. Landlord shall give Tenant at least 30 days' prior
written notice of the amount so due. Upon Landlord's receipt of the Real
Property Tax payment from Tenant, Landlord shall pay the taxes to the county.
If Tenant fails to pay the Real Property Taxes on or before April 1 and December
1, respectively, Tenant shall pay to Landlord any penalty incurred by such late
payment, as well as interest at the Interest Rate from the date such amounts are
due hereunder until the date they are paid by Tenant. Tenant shall pay any Real
Property Tax not included within the county tax assessor's tax statement within
30 days after being billed for same by Landlord. The above dates for payment are
based on the dates currently established by the county as the dates on which
Real Property Taxes become delinquent if not paid. If such delinquency dates
change, the dates on which Tenant must pay such Real. Property Taxes shall be at
least 10 days prior to the delinquency dates. Notwithstanding the above, at any
time, upon prior written notice to Tenant, Landlord shall have the right to
require that Tenant pay one-twelfth of the Real Property Taxes to Landlord
directly, on the first day of each calendar month. Assessments, taxes, fees,
levies and charges may be imposed by governmental agencies for such purposes as
fire protection, street, sidewalk, road, utility construction and maintenance,
refuse removal and for other governmental services which may formerly have been
provided without charge to property owners or occupants. It is the intention of
the parties that all new and increased assessments, taxes, fees, levies and
charges relating to the Land and the Premises are to be included within the
definition of Real Property Taxes for purposes of this Lease. Landlord
represents to Tenant that there are no liens filed against the
<PAGE>
 
Premises or the Land for any Real Property Taxes that are delinquent as of the
date of this Lease and that Landlord shall pay, prior to delinquency, any Real
Property Taxes that are due prior to the Commencement Date.

          B. Taxes on Tenant Improvements and Personal Property. Tenant shall
             --------------------------------------------------              
pay any increase in Real Property Taxes resulting from any and all Alterations
and Tenant Improvements of any kind whatsoever placed in, on or about the
Premises for the benefit of, at the request of, or by Tenant. Tenant shall pay
prior to delinquency all taxes assessed or levied against Tenant's Personal
Property in, on or about the Premises or elsewhere. When possible, Tenant shall
cause its Personal Property to be assessed and billed separately from Landlord'
s real or personal property.

          C. Proration. Tenant's liability to pay Real Property Taxes shall be
             ---------                                                        
prorated on the basis of a 365-day year to account for any fractional portion of
a fiscal tax year included at the commencement or expiration of the Term. With
respect to any assessments which may be levied against or upon the Premises, or
which under the Laws then in force may be evidenced by improvements or other
bonds or may be paid in annual installments, only the amount of such annual
installment (with appropriate proration for any partial year) and interest due
thereon shall be included within the computation of the annual Real Property
Taxes levied against the Premises.

     16.  UTILITIES AND SERVICES

          Tenant shall be responsible for and shall pay promptly to the provider
thereof all charges for water, gas, electricity, computer and telephone cabling
and equipment, refuse pickup, janitorial service and all other utilities,
materials and services finished directly to or used by Tenant in, on or about
the Premises during the Term, together with any taxes thereon. 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, except to the extent
that such failure or interruption is caused by the gross negligence or willful
misconduct of Landlord.

     17.  REPAIR AND MAINTENANCE

          A. Premises.
             ---------

             (i)  Landlord's Obligations. Landlord shall, at its sole cost and
                  ----------------------                                      
expense, keep and maintain in good order, condition and repair the foundation
and subflooring, the exterior walls (excluding the interior of all walls and the

of the foregoing that is caused by the negligence or willful misconduct of
Tenant, its agents, employees, contractors, or invitees shall be repaired at
Tenant's expense. Landlord shall also maintain in good order, condition and
repair, subject to Tenant's obligation to reimburse Landlord for the cost
thereof as provided in Section 17(B)(ii) below, the roof membrane and the HVAC
system for the Premises. Landlord shall obtain HVAC systems preventive

<PAGE>
 
and other preventive maintenance including annual maintenance of ductwork,
interior unit drains and caulking at sheet metal and recaulking of jacks and
vents. Tenant shall have the benefit of all warranties available to Landlord
regarding the equipment in such HVAC systems. It is an express condition
precedent to all obligations of Landlord to repair and maintain that Tenant
shall have notified Landlord in writing of the need for such repairs or
maintenance.

             (ii)  Tenant's Obligations. Subject to the provisions of Section 
                   --------------------

condition and all necessary repairs revealed by such inspection have been
performed promptly.

          B. Outside Areas.
             ------------- 

             (i)  Landlord's Obligations. Landlord shall maintain all Outside 
                  ----------------------
Areas; however, if Landlord so elects, Tenant shall operate and maintain that
portion of the Outside Areas designated by Landlord at Tenant's sole expense.
Landlord at all times shall have exclusive control of the Outside Areas and may
at any time temporarily close any part thereof, upon not less than 24 hours'
prior written notice to Tenant, so long as such closure does not materially and
adversely impair Tenant's access to the parking, area and/or the Premises.
Landlord may exclude and restrain anyone from any part of the Outside Areas,
except for the bona fide employees, agents and invitees of Tenant who use the
Outside Areas in accordance with the CC&R's and all reasonable rules and
regulations promulgated by Landlord from time to time. Landlord may change the
configuration, location or other elements of the Outside Areas, but Landlord may
not reduce the number of parking spaces available to the Premises below the
number required by applicable Laws to permit use of the Premises for the
purposes set forth in this Lease, nor shall Landlord voluntarily reduce the
number of parking spaces available to the Premises below the number of parking
spaces available to the Premises as of the Commencement Date. In exercising any
of the above rights, Landlord shall make a reasonable effort to minimize any
disruption of Tenant's business. 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.

             (ii)  Tenant to Pay Operating Expenses. Tenant shall pay, as 
                   --------------------------------
Additional Rent, all reasonable out-of-pocket costs and expenses paid or
incurred by Landlord in maintaining, repairing and replacing the roof membrane
and the HVAC system, and managing, maintaining, and repairing the Outside Areas
(the "Operating Expenses") during the Term. The Operating Expenses shall
<PAGE>
 
Include, without limitation, the cost of any policies of insurance covering the
Outside Areas, management fees paid to third parties or to management companies
owned by, or management divisions of Landlord, and the cost of labor, materials,
supplies and services used or consumed in maintaining, operating and repairing
the roof membrane, the HVAC system and the Outside Areas, including maintaining,
repairing and replacing, as needed, the roof membrane, the HVAC system and its
components, landscaping and sprinkler systems, and maintaining, restriping,
resurfacing, and repairing concrete walkways and paved parking areas.

             (iii) Monthly Payments. From and after the Commencement Date, 
                   ----------------
Tenant shall pay to Landlord on the first day of each calendar month of the Term
an amount estimated by Landlord to be the monthly Operating Expenses. The
estimated monthly charge may be adjusted by Landlord at the end of any calendar
month 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 120 days
following the end of each calendar year Landlord shall furnish Tenant a 
statement of the actual Operating Expenses for the calendar Year and the
payments made by Tenant with respect to such period. If Tenant's payments for
the Operating Expenses are less than the amount of the actual Operating
Expenses, Tenant shall pay Landlord the deficiency within 30 days after receipt
of such statement. If Tenant's payments exceed the actual Operating Expenses,
Landlord shall either offset the excess against the Operating Expenses next
thereafter to become due to Landlord, or shall refund the amount of the
overpayments to Tenant, in cash, as Landlord shall elect. There shall be
appropriate prorations of the Operating Expenses as of the Commencement Date and
expiration of the Term.

             (iv)  Tenant's Right to Audit.  Within six months after delivery to
                   -----------------------                                     
Tenant of any statement of actual Operating Expenses, Tenant shall have the
right, by written notice to Landlord, to dispute any Operating Expenses
reflected in such statement. If such dispute is not settled within 60 days after
such notice has been delivered to Landlord, the dispute shall be resolved
pursuant to an audit to be conducted by a firm of certified public accountants
(an "Audit Professional") mutually acceptable to Landlord and Tenant. If
Landlord and Tenant cannot agree on an Audit Professional within 30 days, then
Landlord and Tenant shall each, within 15 days, select an Audit Professional and
the two Audit Professionals so selected shall select a third Audit Professional
which shall be the Audit Professional to resolve the dispute. The Audit
Professional selected (the "Selected Auditor") shall be entitled to review all
books and records relating to the disputed Operating Expenses. Such review shall
be conducted during normal business hours at the office of Landlord's property
manager. If the Selected Auditor's determination shows that the aggregate
Operating Expenses in the disputed statement exceed the actual Operating
Expenses for the period, covered by such statement by an amount greater than
five percent (5%), the cost of the audit shall be paid by Landlord; otherwise,
the cost of the audit shall be paid by Tenant, if such determination reflects an
underpayment of Operating Expenses by Tenant, then Tenant shall pay the
deficiency to Landlord within 30 days thereafter, If such determination reflects
an overpayment of Operating Expenses by Tenant, then such amount shall be
credited against the next monthly installment(s) of Operating Expenses that are
due hereunder. Landlord shall maintain all books and records supporting any
statement of Operating Expenses for a period of not less than three years
following the preparation of such statement. The rights and obligations of
Tenant and Landlord under this Section 17.B.(iv) shall survive the expiration or
sooner termination of this Lease.
<PAGE>
 
          C. Compliance with Laws. Tenant at its sole cost shall promptly comply
             --------------------                                               
with all Laws in effect from time to time during the Term that relate to the use
or occupancy of the Premises or privileges appurtenant to or in connection with
the enjoyment of the Premises. If such Laws require any Alterations to the Land
and/or the Premises, the Alterations shall be governed by Section 13 of this
Lease. If, however, the Land and/or the Premises are not in compliance with all
Laws applicable to the Land and/or the Premises on the date that Landlord
delivers possession of the Premises to Tenant, then Landlord shall be
responsible, at its sole cost and expense, for bringing the same into
compliance; provided, however, that the foregoing shall not apply to, and Tenant
shall remain solely responsible for, any compliance with Laws obligations that
are triggered by the construction of the Tenant Improvements or the permitting
for the same, including any upgrades to the Premises which may be required to
comply with such Laws.

          D. Capital Costs. If Landlord's accountants reasonably determine,
             -------------                                                 
based on Generally Accepted Accounting Principles, that any amounts for which
Tenant is responsible under this Section 17 must be capitalized rather than
expensed, then each year during the Term Tenant shall pay only the properly
chargeable portion of capitalized costs during such year based on Landlord's
reasonable determination of the useful life of the applicable capital
improvement, together with interest on the amortized balance at the Interest
Rate.

          E. Tenant's Right to Perform Landlord's Obligations. If Landlord fails
             ------------------------------------------------                   
to perform any of its repair and maintenance obligations under Sections 17(A)(i)
or 17(B)(i), and such failure continues for more than thirty (30) days after
written notice from Tenant.  Tenant shall have the right, but not the
obligation, to perform such repairs and/or maintenance. In the event of an
emergency involving an immediate threat of personal injury or property damage,
Tenant shall have the right to perform such repairs if Landlord fails to do so
within twenty-four (24) hours after notice from Tenant. In either such event,
Landlord shall reimburse Tenant for the reasonable costs incurred by Tenant to
complete such repairs and/or maintenance within thirty (30) days after receipt
of Tenant's written demand therefor, together with copies of paid invoices
evidencing the costs incurred by Tenant. If Landlord fails to reimburse Tenant
for such costs within such thirty (30) day period, such amount shall accrue
interest at the Interest Rate from the date of expenditure by Tenant until
reimbursed by Landlord. Any repairs and/or maintenance permitted herein shall be
performed in a good and workmanlike manner by licensed and bonded contractors.
If Landlord objects to the repairs and/or maintenance performed by Tenant or the
expenses incurred by Tenant in performing such work, Landlord shall deliver
written notice of Landlord's objection to Tenant within thirty (30) days after
Landlords receipt of Tenant's invoice evidencing the expenses incurred by
Tenant. Landlord's notice shall set forth in reasonable detail Landlord's
reasons for its claim that such repairs and/or maintenance were not required or
were not Landlord's obligation under the terms of this Lease, and/or the reasons
for Landlord's dispute of the expenses incurred by Tenant in performing such
work. If Landlord and Tenant fail to resolve any such dispute within thirty (30)
days after Landlord has notified Tenant of Landlord's objections, the matter
shall be resolved by binding arbitration in accordance with the provisions of
California Code of Civil Procedure Sections 1280 et seq.
<PAGE>
 
     18.  LIENS

          Tenant shall keep the Premises free from any liens arising out of any
work performed, materials furnished or obligations incurred by or on behalf of
Tenant. Tenant hereby defends, indemnifies and holds harmless Landlord and
Landlord's Agents from any and all claims, liability, cost and expense
(including reasonable 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 reasonably
acceptable to Landlord within 30 days after 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 20 days prior to the
commencement of such work, so that Landlord may post and record a Notice of
Nonresponsibility or similar notice. If Tenant fails to so remove any such lien
within the prescribed 30 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 from the date of expenditure at the
Interest Rate.

     19.  RIGHT TO ENTER THE PREMISES

          Tenant shall permit Landlord and Landlord's Agents to enter the
Premises at all reasonable times with at least 24 hours' prior written notice,
except for emergencies in which case no notice shall be required, to inspect the
same, to post Notices of Nonresponsibility and similar notices and "For Sale"
signs (in form and content reasonably acceptable to Tenant), to show the
Premises to interested parties such as prospective lenders and purchasers, to
make necessary repairs, to discharge Tenant's obligations under this Lease when
Tenant has failed to do so after expiration of any cure period provided in this
Lease, and at any reasonable time within six months prior to the expiration of
the Term, to place upon the Premises ordinary "For Lease" signs and to show the
Premises to prospective tenants. The above rights are subject to Tenant's
reasonable security regulations. In exercising any such rights, Landlord shall
make a reasonable effort to minimize any disruption of Tenant's business.

     20.  SIGNS

          Tenant may install building and monument identification signage,
subject to all Laws, the CC&R's and Landlord's prior written approval as to
location, size, design, color and other physical aspects, which approval shall
not be unreasonably withheld. Tenant shall not install any other sign, display
or advertising material that is visible from the exterior of the Premises,
except that Tenant may display, on a temporary basis only, such advertising or
promotional material as is approved by the City of Sunnyvale. Tenant shall be
solely responsible for the cost of any signs, as well as their installation,
maintenance and removal. If Tenant fails to maintain its signs, or if Tenant
fails to remove its signs upon termination of this Lease, Landlord may do so at
Tenant's expense, which Tenant shall pay upon demand with interest from the date
of expenditure at the Interest Rate.
<PAGE>
 
     21.  INSURANCE

          A. Indemnification. Subject to the provisions of Section 22, Tenant
             ---------------                                               
shall defend, indemnify and hold harmless Landlord and Landlord's Agents from
and against any and all claims, loss, liability or expense (including reasonable
attorneys' fees and costs) arising out of the use or occupancy of the Premises
or the Land or any part thereof by Tenant, or the acts or omissions of Tenant,
its employees, agents, contractors or invitees. The foregoing indemnity shall
not, however, apply to any claims, loss, liability or expense to the extent that
any of the same arise from the gross negligence or willful misconduct of
Landlord or Landlord's Agents or from the breach of any of Landlord's
obligations or representations under this Lease. Subject to the provisions of
Section 22, Landlord shall defend, indemnify and hold harmless Tenant and
Tenant's officers, directors, employees and agents from and against any and all
claims, loss, liability or expense (including reasonable attorneys' fees and
costs) arising out of the gross negligence or willful misconduct of Landlord or
Landlord's Agents. The obligations of Landlord and Tenant under this Section
21.A. shall survive this Lease.

          B. Tenant's Insurance. For the protection of Tenant and Landlord, as
             ------------------                                             
their interests may appear, Tenant at its sole cost shall maintain in full force
and effect at all times during the Term, as well as during any period of early
entry, policies of insurance issued by a responsible carrier or carriers
reasonably acceptable to Landlord which afford the following coverages:

             (i)  Commercial general liability insurance in an amount not less
than $5,000,000.00 combined single limit for both bodily injury and property
damage on a per occurrence basis which includes blanket contractual liability
broad form property damage, personal injury, completed operations, products
liability, and fire damage legal (in an amount not less than $25,000.00), naming
Landlord and Landlord's Agents as additional insureds.

             (ii) "All Risk" or "causes of loss - 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 All-Risk form. As long,
as this Lease is in effect, the proceeds of such policy shall be used for the
repair or replacement of the items so insured. Landlord shall have no interest
in the insurance upon Tenant's Personal Property.

             (iii)  Boiler and machinery insurance, including but not limited 
to, steam pipes, pressure pipes, condensation return pipes and other pressure
vessels and HVAC equipment, including miscellaneous electrical apparatus, in an
amount satisfactory to Landlord.

             (iv)  Worker's Compensation Insurance, as required by applicable
Laws.

          C. Premises Insurance. During the Term, as well as during any period
             ------------------                                             
of early entry, Landlord shall maintain "All Risk" or "causes of loss - special
form" property insurance (including without limitation vandalism, malicious
mischief, inflation endorsement, sprinkler leakage
<PAGE>
 
endorsement, and. at Landlord's option, earthquake and flood coverage) on the
Premises 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 coverage in the standard ISO All-Risk form.
Such insurance shall exclude coverage of all Tenant's Personal Property on or in
the Premises, but shall include the Tenant Improvements. Notwithstanding the
above, during the period of early entry, Landlord may elect to carry course of
construction insurance providing similar coverage. The property insurance shall
also include insurance against loss of rents on an "All Risk" basis, including
earthquake and flood, in an amount equal to the Rent, and any other sums payable
under the Lease, for a period not to exceed 12 months from the date of loss.
Such insurance shall name Landlord and Landlord's Agents as named insureds and
include a lender's loss payable endorsement in favor of Landlord's lender (Form
438 BFU Endorsement). Tenant shall reimburse Landlord for the costs of such
policy, monthly, or upon such other periodic basis as Landlord shall elect. If
the insurance premiums are increased, Tenant shall pay such increase within 10
days of notice of such increase. If, however, Landlord elects to maintain
earthquake insurance coverage for the Premises as permitted herein. Tenant shall
be required to pay only such portion of the premium for such insurance coverage
as is then considered to be a commercially reasonable rate for such insurance
for properties similar to the Premises, but in no event shall Tenant be required
to pay more than $45,000.00 per year for earthquake insurance premiums.

          D. 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.

          E. Co-Insurer. If, because Tenant fails to comply with the above
             ----------                                                   
provisions, Landlord is adjudged a co-insurer by its insurance carrier, then any
loss or damage Landlord shall sustain by reason thereof, including reasonable
attorneys' fees and costs, shall be borne by Tenant and shall be paid by Tenant
upon receipt of a bill therefor and evidence of such loss.

          F. Insurance Requirements. All such insurance shall (i) be in a form
             ----------------------                                           
satisfactory to Landlord, (ii) 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, (iii)
                                              -------------------------     
provide that such policies shall not be subject to material alteration or
cancellation except after at least 30 days' prior written notice to Landlord;
and (iv) 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 Tenant entering, onto
the Premises, and upon renewal of such policies, not less than 30 days prior to
the expiration of the term of such coverage. If Tenant fails to procure and
maintain the insurance required under this Lease, Landlord may, but shall not be
required to, order such insurance at Tenant's expense and Tenant shall reimburse
Landlord therefor upon demand. Such reimbursement shall include all costs
incurred by Landlord, including Landlord's reasonable attorneys' fees, with
interest thereon from the date of expenditure at the Interest Rate.

          G. Landlord's Disclaimer. Landlord and Landlord's Agents shall not be
             ---------------------                                             
liable for any loss or damage to persons or property resulting from fire,
explosion, falling plaster, glass, tile or
<PAGE>
 
sheetrock, steam, gas, electricity, water or rain which may leak from any part
of the Premises, or from the pipes, appliances or plumbing works therein or from
the roof, street or subsurface or whatsoever, unless caused by or due to the
gross negligence or willful acts of Landlord or Landlord's Agents. Landlord and
Landlord's Agents shall not be liable for any latent defect in the Premises,
except for Landlord's obligation to maintain and repair the structural portions
of the Premises as described in Section 17.A. (i). Tenant shall give prompt
written notice to Landlord in case of a casualty, accident or repair needed in
the Premises. In no event shall Landlord or Landlord's Agents be liable for
Tenant's lost profits, consequential or exemplary damages, no matter how caused.
Without limiting the above, Landlord shall not be required to provide, and
Tenant expressly waives, any security services with respect to the Premises or
the Land. Landlord shall have no liability for injury or losses due to theft or
burglary or caused by unauthorized persons in the Premises or on the Land.

     22.  WAIVER OF SUBROGATION

          Landlord and Tenant each hereby release and waive all rights of
recovery against the other and their respective agents, and employees 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
would be insured against under any insurance policies required by this Lease or
is otherwise insured against under any other policies which may be in force at
the time of such loss or damage, without regard to the negligence of the party
so released.  Tenant and Landlord each shall cause the insurance policies
obtained by it under this Lease 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.

     23.  DAMAGE OR DESTRUCTION

          A. Landlord's Obligation to Rebuild. If the Premises are damaged or
             --------------------------------                                
destroyed, Landlord shall promptly and diligently repair the Premises unless it
has the right to terminate this Lease as provided below and it elects to so
terminate.

          B. Right to Terminate. Landlord shall have the right to terminate this
             ------------------                                                 
Lease if any of the following events occurs:

             (i)  Insurance proceeds will not be available to pay the cost of 
such repair, excluding any deductible for which Tenant is responsible;

             (ii)  The Premises cannot, with reasonable diligence, be fully rep
aired by Landlord within 90 days after the date of the damage or destruction; or

             (iii) The Premises cannot be safely repaired because of the 
presence of hazardous factors, including without limitation 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 and the basis for such termination
within 30 days after such damage or destruction,
<PAGE>
 
and this Lease shall terminate 15 days after the date Tenant receives such
notice. If Landlord elects not to terminate this Lease, subject to Tenants
termination right set forth below. Landlord shall promptly commence the process
of obtaining necessary permits and approvals and repair of the Premises as soon
as practicable, and this Lease will continue in full force and effect. All
insurance proceeds from insurance under Section 22, 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, except to the extent the casualty was
caused by Landlord's negligence or willful misconduct.

          Tenant shall have the right to terminate this Lease, if the Premises
cannot, with reasonable diligence, be fully repaired within 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 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, by written notice to
Landlord delivered within 30 days after delivery of Landlord's notice.

          C. Limited Obligation to Repair.  Landlord's obligation, should it
             -----------------------------                                  
elect or be obligated to repair or rebuild, shall be limited to the Premises,
Tenant Improvements and Outside Areas.

          D. Abatement of Rent. Rent shall be temporarily abated
             -----------------                                  
proportionately, but only to the extent of any proceeds received by Landlord
from rental abatement insurance described in Section 21 (C), during any period
when, by reason of such damage or destruction, Landlord reasonably determines
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 the 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 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 subsequently enacted.

          E. Damage Near End of Term. Anything in this Lease to the contrary
             -----------------------                                        
notwithstanding, if the Premises are destroyed or damaged during the last 12
months of the Term, then either Landlord or Tenant may cancel and terminate this
Lease as of the date of the occurrence of such damage if the Premises cannot be
restored within 60 days from the date of such damage.  If neither Landlord nor
Tenant elects to so terminate this Lease, the repair of such damage shall be
governed by this Section 23.

     24.  CONDEMNATION

          If title to all of the Premises (or to a portion of the Premises such
that, in Tenant's reasonable opinion, the remaining part is not reasonably
suitable for Tenant's continued occupancy for the
<PAGE>
 
uses permitted by this Lease) is taken for any public or quasi-public use under
any statute or by right of eminent domain, then this Lease shall terminate as of
the date that possession of the Premises or part thereof is taken.  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
Section.

          If any part of the Premises is taken and the remaining part, in
Tenant's reasonable opinion, is reasonably suitable for Tenant's continued
occupancy for the uses permitted by this Lease, then this Lease shall, as to the
part so taken, terminate as of the date that possession of such part of the
Premises is taken and the Rent and other sums payable under this Lease shall be
reduced in the same proportion that Tenant's use of the Premises is reduced.
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 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-, provided that, Tenant shall not be required to assign
to Landlord any separate award made to Tenant for the (a) taking of Tenant's
Personal Property, (b) interruption of Tenant's business or (c) Tenant's
relocation costs.

     25.  ASSIGNMENT AND SUBLETTING

          A. Landlord's Consent. Tenant shall not enter into a Sublet without
             ------------------                                              
Landlord's prior written consent. Landlord's consent shall not be unreasonably
withheld provided that: (i) Tenant has requested in writing Landlord's prior
consent; (ii) the proposed Subtenant is a reputable party of reasonable
financial worth in light of the responsibilities involved and Tenant shall have
provided Landlord with reasonable proof thereof, including without limitation
such financial information as Landlord may reasonably request; (iii) Tenant is
not in default at the time it requests such consent; and (iv) no alteration of
the Premises will be required unless approved in writing by Landlord pursuant to
Section 13 of this Lease. Tenant's request for consent shall include information
reasonably sufficient to evaluate the above criteria, as well as a copy of the
assignment or sublease to be signed by the proposed Subtenant, including a
detailed description of the premises to be Sublet and a detailed statement of
all terms and conditions of the proposed Sublet. Landlord may request additional
information for evaluation if Landlord reasonably deems the information
submitted by Tenant to be insufficient. Landlord shall have 15 days after
receipt of Tenant's written request and all required information in which to
review and respond to the request. Consent by Landlord to any one Sublet shall
not be construed as relieving Tenant from obtaining Landlord's express written
consent to any further Sublet. Landlord's consent to any requested Sublet shall
not waive Landlord's right to refuse to consent to any other such request or to
terminate this Lease if such request is made, all as provided in 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 in this Lease,
Tenant shall not be released from personal 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.
<PAGE>
 
          B.  Landlord's Right to Terminate. Notwithstanding anything in this
              -----------------------------                                  
Section 25 to the contrary, in the event Tenant requests Landlord's consent to
Sublet all or any part of the Premises or all or any part of its interest in
this Lease. Landlord shall have the right to: (i) consent to such Sublet; (ii)
refuse to grant such consent, with such consent not to be unreasonably withheld
(but subject to the conditions set forth in this Section 25); or (iii) elect to
terminate this Lease as to the portion of the Premises proposed to be Sublet if
such Sublet is for the then remaining, Term of this Lease; provided that, if
Landlord refuses to grant such consent and elects to terminate the Lease as to
such portion of the Premises, Tenant shall have the right within 10 days after
notice of Landlord's exercise of its right to terminate to withdraw Tenant's
request for such consent and remain in possession of the Premises under the
terms and conditions of this Lease.  In the event the Lease is terminated as set
forth above, such termination shall be effective as of the date set forth in a
written notice from Landlord to Tenant, which date shall in no event be less
than 30 days, nor more than 60 days, following such notice.

          If Landlord 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 Section 25(A), subject, however, at Landlord's election,
to the condition that 50% of any excess of the Subrent over the Rent (less
reasonable attorneys' fees and leasing commissions paid by Tenant on the
Sublease) shall be paid to Landlord.  Any such Subrent shall be payable to
Landlord concurrent with the Monthly Rent under Section 5(A).

          C. Proration. If a portion of the Premises is Sublet, the prorata
             ---------                                                     
share of the Rent attributable to such partial area of the Premises shall be
determined by Landlord by dividing the Rent payable by Tenant under this Lease
by the total leasable 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.

          D. Permitted Transfers. So long as International Network Services is
             -------------------                                              
the Tenant in possession of the Premises and is not in default, Tenant shall
have the right, subject to the following terms and conditions and without the
consent of Landlord, to Sublet its interest in the Lease (i) to any corporation
which is a successor to Tenant either by merger or consolidation or (ii) to a
purchaser of all or substantially all of Tenant's assets (provided such
purchaser shall also have assumed substantially all of Tenant's liabilities), or
(iii) to a corporation or other entity which shall control, be under the control
of, or be under common control with International Network Services, (the term
"control" shall be deemed to mean ownership of more than 50% of the outstanding
voting stock of a corporation, or other majority equity and control interest if
Tenant is not a corporation; any such entity is a "Related Entity"), upon the
conditions that (1) the principal purpose of such Sublet is not the acquisition
of Tenant is interest in this Lease (except if the Sublet is made to a Related
Entity and is made for a valid intracorporate business purpose and is not made
to circumvent the provisions of this Section 25), and (2) any such Subtenant
shall have a net worth and annual income and cash flow, determined in accordance
with generally accepted accounting principles, consistently applied, after
giving effect to such Sublet, equal to or greater that Tenant's as of the
Execution Date, as determined by Landlord in its sole discretion, exercised in
good faith. Within ten days after execution thereof, Tenant shall deliver to
Landlord (x) a duplicate original of the instrument evidencing the Subrent, (y)
<PAGE>
 
if applicable, evidence reasonably satisfactory to Landlord establishing
compliance by the Subtenant with the net worth, income and cash flow
requirements of clause (2) above, and (z) an instrument in form and substance
reasonably satisfactory to Landlord, duly executed by the Subtenant, in which
the Subtenant assumes and agrees to be bound by the terms, conditions and
covenants of this Lease.

          E. Landlord's Review Costs. All documents utilized by Tenant to
             -----------------------                                     
evidence any Sublet shall be subject to prior approval of Landlord or its
counsel. and in the event any alterations to the Premises are proposed,
Landlord's architect and engineers. Tenant shall pay promptly upon billing any
and all reasonable fees of attorneys and other consultants and other costs
reasonably incurred by Landlord for the review or preparation of any documents
in connection with a proposed Sublet, up to a maximum of $3,000.00 per Sublet.

     26.  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 under this Lease within five business days after the date such Rent or
other sum is 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 20 days after written notice from Landlord where such breach
could reasonably be cured within such 20 day period; provided that, where such
failure could not reasonably be cured within the 20 day period, Tenant shall not
be in default if it commences such, performance within the 20 day period and
diligently prosecutes the same to completion; or

             (iii)  The making by Tenant of any general assignment for the 
benefit of creditors; the filing, by or against Tenant of a petition to have
Tenant adjudged a bankrupt or of a petition for reorganization or arrangement
under any law relating to bankruptcy (unless, in the case of a petition filed
against Tenant, the same is dismissed with 60 days after such filing); the
appointment of a trustee or receiver to take possession of all or substantially
all of Tenant's assets located at the Premises or of Tenant's interest in this
Lease, where possession is not restored to Tenant with 60 days after such
appointment; the attachment, execution or other judicial seizure of all or
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where such seizure is not discharged within 60 days
thereafter; or if Tenant is generally not paying its debts as they become due.

          B. Remedies. Upon a default, Landlord shall have the following
             --------                                                   
remedies, in addition to all other rights and remedies provided by this Lease,
at law or in equity, 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.
<PAGE>
 
             (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, attorneys' fees and costs,
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. 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:

                   (1)  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

                   (2)  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 proves could have been reasonably avoided; plus

                   (3)  The worth at the time of award of the amount by which 
the unpaid Rent and other sums due and payable for the balance or the Term after
the time of award exceeds the amount of such Rent loss that Tenant proves could
be reasonably avoided; plus

                   (4)  Any other amount necessary to compensate Landlord for 
all the detriment approximately 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 incurred
by Landlord: (w) in retaking possession of the Premises; (x) 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; (y) for leasing commissions; or (z) for
any other costs necessary or appropriate to relet the Premises; plus

                   (5)  At Landlord's election, such other amounts in addition 
to or in lieu of the above 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
Sections 25(B)(ii)(1) and 25(B)(ii)(2) is computed by allowing interest at the
Interest Rate on the unpaid Rent and other stuns 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 Section 25(B)(ii)(3) is computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus 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 under this Lease.

             (iii)  Upon termination of this Lease, Landlord may re-enter the
Premises and remove all persons and property from the Premises. Such property
may be removed, transported and stored
<PAGE>
 
in a public warehouse or elsewhere at the cost of and for the account of Tenant.
No re-entry or taking possession of the Premises by Landlord pursuant to this
Section shall be construed as an election to terminate this Lease unless a
written notice of such intention is given to Tenant.


          C. Landlord's Default. Landlord shall not be deemed to be in default
             ------------------                                               
in the performance of any obligation required to be performed by it under this
Lease unless and until it has failed to perform such obligation within the time
provided herein or, if none is provided, within 20 days after receipt of written
notice by Tenant to Landlord specifying Landlord's default. If the nature of
Landlord's obligation is such that more than 20 days are required for its
performance, then Landlord shall not be in default if it commences such
performance within the 20 day period and diligently prosecutes the same to
completion.

     27.  SUBORDINATION

          A. Documentation. This Lease is subject and subordinate to all ground
             -------------                                                     
and underlying leases, mortgages and deeds of trust (collectively
"ENCUMBRANCES") which now affect the Premises, to all documents of record and to
the CC&R's and all renewals, modifications, consolidations, replacements and
extensions thereof-, provided that, if the holder or holders of any such
Encumbrance ("HOLDER") shall require that this Lease be prior and superior
thereto, within 10 days after written request from Landlord to Tenant, Tenant
shall execute, have acknowledged and deliver any and all documents which
Landlord or Holder reasonably deems necessary 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 subsequently be
executed covering the Premises or the Land, as well as any renewals,
modifications, consolidations, replacements or extensions thereof. Landlord
represents to Tenant that, as of the date of this Lease, there are no
Encumbrances which affect the Premises. As to any Encumbrances entered into
subsequent to the Execution Date, it shall be a condition to the subordination
of this Lease that Landlord shall concurrently obtain from the Holder a covenant
in writing that, in the event of foreclosure of any such Encumbrance (or deed in
lieu or other arrangement in lieu thereof), so long as Tenant is not in default,
Holder and its designees and successors shall recognize Tenant's rights under
this Lease. Subject to the foregoing within 10 days after Landlord's written
request, Tenant shall execute any and all documents reasonably required by
Landlord or the Holder to make this Lease subordinate to any Encumbrance. If
Tenant fails to do so, it shall be deemed that this Lease is subordinated.

          Notwithstanding anything to the contrary in this Section 27, Tenant
hereby attorns and agrees to attorn to any entity purchasing or otherwise
acquiring the Premises and the Land at any sale or other proceeding of pursuant
to the exercise of any other rights, powers or remedies under any Encumbrance.

     28.  NOTICES

          All notices, demands, statements or communications (collectively,

Lease shall be in writing and be sent by electronically confirmed telecopy,
nationally recognized overnight courier service, or United States certified or
registered mail, postage prepaid, return receipt requested, or delivered

with a copy to Landlord at the address specified in the Lease Summary, or to
such other firm or to such other place as Landlord may from time to time
designate in a Notice to Tenant. Any Notice will be deemed given upon the date
delivered if delivered personally, on the same day if given before 5:00 PM
(recipient's time) on any work day (or on the next work day if given after 5:00
PM or on other than a work day) by electronically confirmed telecopy, the next
business day if sent by nationally recognized courier service, or upon receipt
or refusal of receipt if sent by United States mail, as provided above.

     29.  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 or establish any
term, condition or covenant of this Lease or right of either party, the
prevailing party shall be entitled to recover reasonable attorneys' fees and
costs in such action or proceedings (or in a separate action brought for that
purpose).

     30.  ESTOPPEL CERTIFICATES

          Tenant shall within 10 days following written request by Landlord:

          A. Execute and deliver to Landlord estoppel certificates, in the form
prepared by Landlord (i) certifying that this Lease is unmodified and in full
force an 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, (ii)
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 Landlord,
stating the nature of such uncured defaults, and (iii) certifying as to any
other information concerning the Lease as may be reasonably requested by
Landlord, the Holder or prospective Holder of any Encumbrance, or a prospective
purchaser of the Land and the Premises. Tenant's failure to deliver an estoppel
certificate 10 days after delivery of Landlord's written request therefor shall
be conclusive upon Tenant that (1) this Lease is in full force and effect,
without modification except as may be represented by Landlord, (2) there are now
no uncured defaults in Landlord's performance and (3) no Rent has been paid in
advance.

          B. Deliver to Landlord the current financial statements of Tenant, and

statements, with an opinion of a certified public accountant, including a
balance sheet and profit and loss statement for the most recent prior year, all

<PAGE>
 
     31.  TRANSFER OF THE PREMISES BY LANDLORD

          In the event of any conveyance of the Premises and the Land 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 accruing after the date of such
conveyance and assignment provided that the transferee assumes all of Landlord's
obligations under this Lease and, subject to the provisions of Section 27,
Tenant agrees to attorn to such transferee.

     32.  LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS

          If Tenant is in default 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, cure such default to the extent Landlord may deem
desirable, and in connection with the same, pay expenses and employ counsel. All
sums so paid by Landlord and all penalties, interest and costs in connection
with the same shall be due and payable by Tenant on the next day after any such
payment by Landlord, together with interest thereon from the date of
expenditure, at the Interest Rate 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.

     33.  NO PERSONAL LIABILITY OF LANDLORD

          Tenant shall look solely to the Landlord's then equity interest in the
Premises and the Land for recovery of any judgment from Landlord. Neither
Landlord nor any of Landlord s Agents nor any successor in interest to Landlord
or Landlord's Agents shall ever be personally liable for any such judgment, or
for the payment of any monetary obligation to Tenant. The covenants of Landlord
contained in this Lease shall be binding, upon Landlord and Landlord's
successors only with respect to breaches occurring during Landlord's and
Landlord's successors' respective periods of ownership of the Premises and the
Land.

     34.  HOLDER PROTECTION

          If Landlord defaults under this Lease, Tenant shall notify any Holder
of an Encumbrance, and offer such Holder a reasonable opportunity to cure the
default, including time to obtain possession of the Premises and Land by power
of sale or a judicial foreclosure, if such should prove necessary to effect a
cure. Landlord shall notify Tenant of the identity and address of any Holder for
purpose of such notice.

     35.  BROKERS

          Landlord and Tenant hereby warrant to each other that they have had no
dealings with any real estate broker, agent or finder in connection with the
negotiation of this Lease, excepting only the real estate brokers or agents
specified in the Lease Summary, and that they know of no other real estate
broker, agent, finder or other party who is entitled to a commission in
connection with this Lease. Each party shall defend, indemnify and hold the
other party harmless from and against and all
<PAGE>
 
claims, loss, liability or expense (including attorneys' fees and costs) with
respect to any leasing commission or equivalent compensation alleged to be owing
on account of the indemnifying party's dealings with any real estate broker,
agent, finder or other party, except for those specified in the Lease Summary.

     36.  ACCEPTANCE

          This Lease shall only become effective and binding upon full execution
and delivery. Neither party shall record this Lease nor a short form memorandum
of it.

     37.  ENVIRONMENTAL PROVISIONS

addition to Tenant's obligations and Landlord's rights set forth elsewhere in

     7.  Governing Law.  This letter shall be governed by and construed in
         -------------                                                    
accordance with the laws of the State of California.

     8.  Arbitration.
         ----------- 

     (a) Arbitration.  Upon the demand of any party, any Dispute shall be
         -----------                                                     
resolved by binding arbitration (except as set forth in (e) below) in accordance
with the terms of this letter.  A "Dispute" shall mean any action, dispute,
claim or controversy of any kind, whether in contract or tort, statutory or
common law, legal or equitable, now existing or hereafter arising under or in
connection with, or in any way pertaining to, any of the Loan Documents, or any
past, present or future extensions of credit and other activities, transactions
or obligations of any kind related directly or indirectly to any of the Loan
Documents, including without limitation, any of the foregoing arising in
connection with the exercise of any self-help, ancillary or other remedies
pursuant to any of the Loan Documents.  Any party may by summary proceedings
bring an action in court to compel arbitration of a Dispute.  Any party who
fails or refuses to submit to arbitration following a lawful demand by any other
<PAGE>
 
International Network Services
August 14, 1998
Page 13


party shall bear all costs and expenses incurred by such other party in
compelling arbitration of any Dispute.

     (b)  Governing Rules.  Arbitration proceedings shall be administered by the
          ---------------                                                       
American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules.  All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the Loan
Documents.  The arbitration shall be conducted at a location in California
selected by the AAA or other administrator.  If there is any inconsistency
between the terms hereof and any such rules, the terms and procedures set forth
herein shall control.  All statutes of limitation applicable to any Dispute
shall apply to any arbitration proceeding.  All discovery activities shall be
expressly limited to matters directly relevant to the Dispute being arbitrated.
Judgment upon any award rendered in an arbitration may be entered in any court
having jurisdiction; provided however, that nothing contained herein shall be
deemed to be a waiver by any party that is a bank of the protections afforded to
it under 12 U.S.C. (S)91 or any similar applicable state law.

     (c)   No Waiver; Provisional Remedies, Self-Help and Foreclosure.  No
           ----------------------------------------------------------     
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding.  The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

     (d) Arbitrator Qualifications and Powers; Awards.  Arbitrators must be
         --------------------------------------------                      
active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise in the substantive law
applicable to the subject matter of the Dispute.  Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing.  Arbitrators (I) shall resolve all Disputes in
accordance with the substantive law of the state of California, (ii) may grant
any remedy or relief that a court of the state of California could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award 
<PAGE>
 
International Network Services
August 14, 1998
Page 14


recovery of all costs and fees, to impose sanctions and to take such other
actions as they deem necessary to the same extent a judge could pursuant to the
Federal Rules of Civil Procedure, the California Rules of Civil Procedure or
other applicable law. Any Dispute in which the amount in controversy is
$5,000,000 or less shall be decided by a single arbitrator who shall not render
an award of greater than $5,000,000 (including damages, costs, fees and
expenses). By submission to a single arbitrator, each party expressly waives any
right or claim to recover more than $5,000,000. Any Dispute in which the amount
in controversy exceeds $5,000,000 shall be decided by majority vote of a panel
of three arbitrators; provided however, that all three arbitrators must actively
participate in all hearings and deliberations.

     (e)  Judicial Review.  Notwithstanding anything herein to the contrary, in
          ---------------                                                      
any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law.  In such arbitrations (I) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
California, and (iii) the parties shall have in addition to the grounds referred
to in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
California.  Judgment confirming an award in such a proceeding may be entered
only if a court determines the award is supported by substantial evidence and
not based on legal error under the substantive law of the state of California.

     (f) Real Property Collateral; Judicial Reference.  Notwithstanding anything
         --------------------------------------------                           
herein to the contrary, no Dispute shall be submitted to arbitration if the
Dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (I) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or benefits
that might accrue to them by virtue of the single action rule statute of
California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
<PAGE>
 
International Network Services
August 14, 1998
Page 15


indebtedness and obligations, shall remain fully valid and enforceable.  If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638.  A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures.  Judgment upon the decision rendered by a referee
shall be entered in the court in which such proceeding was commenced in
accordance with California Code of Civil Procedure Sections 644 and 645.

     (g) Miscellaneous.  To the maximum extent practicable, the AAA, the
         -------------                                                  
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA.  No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any judicial review rights
set forth herein.  If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provision most
directly related to the Loan Documents or the subject matter of the Dispute
shall control.  This arbitration provision shall survive termination, amendment
or expiration of any of the Loan Documents or any relationship between the
parties.

                                 TERM COMMITMENT NOTE


$10,000,000.00                                            Palo Alto, California
                                                                August 14, 1998

     FOR VALUE RECEIVED, the undersigned INTERNATIONAL NETWORK SERVICES
("Borrower") promises to pay to the order of WELLS FARGO BANK, NATIONAL
ASSOCIATION ("Bank") at its office at 400 Hamilton Avenue, P.O. Box 150, Palo
Alto, California or at such other place as the holder hereof may designate, in
lawful money of the United States of America and in immediately available funds,
the principal sum of Ten Million Dollars ($10,000,000.00), or so much thereof as
may be advanced and be outstanding, with interest thereon during the Revolving
Period (defined below), to be computed on each advance from the date of its
disbursement (computed on the basis of a 360-day year, actual days elapsed)
either (i) at a fluctuating rate per annum one-half of one percent (0.50%) below
the Prime Rate in effect from time to time, or (ii) at a fixed rate per annum
determined by Bank to be one and one-half percent (1.50%) above Bank's LIBOR in
effect on the first day of the applicable Fixed Rate Term. When interest is
determined in relation to the Prime Rate, each change in the rate of interest
hereunder shall become effective on the date each Prime Rate change is announced
within Bank.  With respect to each LIBOR  option selected hereunder, Bank is
hereby authorized to note the date, principal amount, interest rate and Fixed
Rate Term applicable thereto and any payments made thereon on Bank's books and
records (either manually or by electronic entry) and/or on any schedule attached
to this Note, which notations shall be prima facie evidence of the accuracy of
the information noted.

A.   DEFINITIONS:

     As used herein, the following terms shall have the meanings set forth after
each:

     1.  "Business Day" means any day except a Saturday, Sunday or any other day
designated as a holiday under Federal or California statute or regulation.
<PAGE>
 
International Network Services
August 14, 1998
Page 18


     2.  "Fixed Rate Term" means a period commencing on a Business Day and
continuing for one (1), two (2), or three (3) months, as designated by Borrower,
during which the outstanding principal balance of this Note bears interest
determined in relation to Bank's LIBOR ; provided however, that no Fixed Rate
Term commencing during the Revolving Period shall extend beyond February 14,
2000, and no Fixed Rate Term commencing during the Term Out Period shall extend
beyond February 14, 2003.  If any Fixed Rate Term would end on a day which is
not a Business Day, then such Fixed Rate Term shall be extended to the next
succeeding Business Day.

     3.  "LIBOR" means the rate per annum (rounded upward, if necessary, to the
nearest whole 1/8 of 1%) and determined pursuant to the following formula:

     LIBOR =               Base LIBOR
                -------------------------------
                100% - LIBOR Reserve Percentage

          (a) "Base LIBOR" means the rate per annum for United States dollar
deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the
understanding that such rate is quoted by Bank for the purpose of calculating
effective rates of interest for loans making reference thereto, on the first day
of a Fixed Rate Term for delivery of funds on said date for a period of time
approximately equal to the number of days in such Fixed Rate Term and in an
amount approximately equal to the principal amount to which such Fixed Rate Term
applies.  Borrower understands and agrees that Bank may base its quotation of
the Inter-Bank Market Offered Rate upon such offers or other market indicators
of the Inter-Bank Market as Bank in its discretion deems appropriate including,
but not limited to, the rate offered for U.S. dollar deposits on the London
Inter-Bank Market.

          (b) "LIBOR Reserve Percentage" means the reserve percentage prescribed
by the Board of Governors of the Federal Reserve System (or any successor) for
"Eurocurrency Liabilities" (as defined in Regulation D of the Federal Reserve
Board, as amended), adjusted by Bank for expected changes in such reserve
percentage during the applicable Fixed Rate Term.

     5.  "Prime Rate" means at any time the rate of interest most recently
announced within Bank at its principal office in San Francisco as its Prime
Rate, with the understanding that the 
<PAGE>
 
International Network Services
August 14, 1998
Page 19


Prime Rate is one of Bank's base rates and serves as the basis upon which
effective rates of interest are calculated for those loans making reference
thereto, and is evidenced by the recording thereof after its announcement in
such internal publication or publications as Bank may designate.

     6.  "Revolving Period" shall mean the period commencing on the date of this
Note and ending on the earlier of February 14, 2000 or the date Bank's
obligation to make advances on this Note terminates.

     7.  "Term-Out Period" means the period commencing February 15, 2000 and
ending February 14, 2003.

B.   INTEREST:

     1.  Payment of Interest.  Interest accrued on this Note shall be payable on
         -------------------                                                    
the first day of each month, commencing September 1, 1998.

     2.  Selection of Interest Rate Options.  At any time any portion of the
         ----------------------------------                                 
outstanding principal balance of this Note bears interest determined in relation
to Bank's LIBOR , it may be continued by Borrower at the end of the Fixed Rate
Term applicable thereto so that it bears interest determined in relation to the
Prime Rate or in relation to Bank's LIBOR  for a new Fixed Rate Term designated
by Borrower.  At any time any portion of the outstanding principal balance of
this Note bears interest determined in relation to the Prime Rate, Borrower may
convert all or a portion thereof so that it bears interest determined in
relation to Bank's LIBOR  for a Fixed Rate Term designated by Borrower.  At the
time Borrower wishes to select the LIBOR  option for the outstanding principal
balance hereof at the end of each Fixed Rate Term, Borrower shall give Bank
notice specifying (a) the interest rate option selected by Borrower and (b) if
the LIBOR  option is selected, the length of the applicable Fixed Rate Term.
Any such notice may be given by telephone so long as, with respect to each LIBOR
option selected by Borrower, (i) Bank receives written confirmation from
Borrower not later than three (3) Business Days after such telephone notice is
given, and (ii) such notice is given to Bank prior to 10:00 a.m., California
time, on the first day of the Fixed Rate Term.  For each LIBOR  option requested
hereunder, Bank will quote the applicable fixed rate to 
<PAGE>
 
International Network Services
August 14, 1998
Page 20


Borrower at approximately 10:00 a.m., California time, on the first day of the
Fixed Rate Term. If Borrower does not immediately accept the rate quoted by
Bank, any subsequent acceptance by Borrower shall be subject to a
redetermination by Bank of the applicable fixed rate; provided however, that if
Borrower fails to accept any such rate by 11:00 a.m., California time, on the
Business Day such quotation is given, then the quoted rate shall expire and Bank
shall have no obligation to permit a LIBOR option to be selected on such day. If
no specific designation of interest is made at the time any advance is requested
hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to have
made a Prime Rate interest selection for such advance or the principal amount to
which such Fixed Rate Term applied. Notwithstanding the foregoing, during the
Term-Out Period, selection of interest rate by Borrower must apply to the entire
outstanding principal balance.

     3.  Additional LIBOR Provisions.
         --------------------------- 

          (a) If Bank at any time shall determine that for any reason adequate
and reasonable means do not exist for ascertaining Bank's LIBOR , then Bank
shall promptly give notice thereof to Borrower.  If such notice is given and
until such notice has been withdrawn by Bank, than (i) no new LIBOR  option may
be selected by Borrower, and (ii) any portion of the outstanding principal
balance hereof which bears interest determined in relation to Bank's LIBOR ,
subsequent to the end of the Fixed Rate Term applicable thereto, shall bear
interest determined in relation to the Prime Rate.

          (b) If any law, treaty, rule, regulation or determination of a court
or governmental authority or any change therein or in the interpretation or
application thereof (each, a "Change in Law") shall make it unlawful for Bank
(i) to make LIBOR  options available hereunder, or (ii) to maintain interest
rates based on Bank's LIBOR , then in the former event, any obligation of Bank
to make available such unlawful LIBOR  options shall immediately be canceled,
and in the latter event, any such unlawful LIBOR -based interest rates then
outstanding shall be converted, at Bank's option, so that interest on the
portion of the outstanding principal balance subject thereto is determined in
relation to the Prime Rate; provided however, that if any such Change in Law
shall permit any LIBOR -based interest rates to remain in effect until the
expiration of the Fixed Rate Term applicable thereto, then such 
<PAGE>
 
International Network Services
August 14, 1998
Page 21


permitted LIBOR-based interest rates shall continue in effect until the
expiration of such Fixed Rate Term. Upon the occurrence of any of the foregoing
events, Borrower shall pay to Bank immediately upon demand such amounts as may
be necessary to compensate Bank for any fines, fees, charges, penalties or other
costs incurred or payable by Bank as a result thereof and which are attributable
to any LIBOR options made available to Borrower hereunder, and any reasonable
allocation made by Bank among its operations shall be conclusive and binding
upon Borrower.

          (c) If any Change in Law or compliance by Bank with any request or
directive (whether or not having the force of law) from any central bank or
other governmental authority shall:

               (i)  subject Bank to any tax, duty or other charge with respect
                    to any LIBOR  options, or change the basis of taxation of
                    payments to Bank of principal, interest, fees or any other
                    amount payable hereunder (except for changes in the rate of
                    tax on the overall net income of Bank);

              (ii)  impose, modify or hold applicable any reserve, special
                    deposit, compulsory loan or similar requirement against
                    assets held by, deposits or other liabilities in or for the
                    account of, advances or loans by, or any other acquisition
                    of funds by any office of Bank; or

             (iii)  impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining any LIBOR  options hereunder and/or to reduce
any amount receivable by Bank in connection therewith, then in any such case,
Borrower shall pay to Bank immediately upon demand such amounts as may be
necessary to compensate Bank for any additional costs incurred by Bank and/or
reductions in amounts received by Bank which are attributable to such LIBOR
options.  In determining which costs incurred by Bank and/or reductions in
amounts received by Bank are attributable to any LIBOR  options made available
to Borrower hereunder, any 
<PAGE>
 
International Network Services

Page 22


reasonable allocation made by Bank among its operations shall be conclusive and
binding upon Borrower.

  4. Default Interest.  From and after the maturity date of this Note, or such
     ----------------                                                         
earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to three percent (3%) above
the higher of (i) the Prime Rate or (ii) the rate of interest then in effect
applicable to this Note.

C.   BORROWING, REPAYMENT, AND PREPAYMENT:

     (a) Borrowing and Repayment.  Borrower may from time to time during the
         -----------------------                                            
Revolving Period borrow and partially or wholly repay its outstanding borrowings
and reborrow, subject to all of the limitations, terms and conditions of this
Note and of any document executed in connection with or governing this Note;
provided that the total borrowings under this Note shall not exceed the
principal amount stated above.  The unpaid principal balance of this obligation
at any time shall be the total amounts advanced hereunder by the holder hereof
less the amount of principal payments made hereon by or for any Borrower, which
balance may be endorsed hereon from time to time by the holder.

     (b) Required Principal Payments during Term-Out Period.   Provided Borrower
         --------------------------------------------------                     
is not in default under the terms of this Note, the Letter Agreement, or any
other document or instrument entered in connection with this Note, and at
Borrower's option, the outstanding principal balance of this Note on February
14, 2000 shall be amortized over three (3) years, and thereafter principal shall
be payable on the first day of each month in equal successive installments over
said amortization term, commencing March 1, 2000, and continuing up to and
including February 1, 2003, with a final installment consisting of all remaining

any person, with respect to advances deposited to the credit of any account of
Borrower with the holder, which advances, when so deposited, shall be
conclusively presumed to have been made to or for the benefit of Borrower
regardless of the fact that persons other than those authorized to request
advances may have authority to draw against such account. The holder shall have
no obligation to determine whether any person requesting an advance is or has
been authorized by Borrower.

     2.  Application of Payments.  Each payment made on this Note shall be
         -----------------------                                          
credited first, to any interest then due and second, to the outstanding
principal balance hereof.  All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate, if any, and second, to the outstanding
principal balance of this Note which bears interest determined in relation to
Bank's LIBOR , with such payments applied to the oldest Fixed Rate Term first.

     3.  Prepayment.
         ---------- 

          (a) Prime Rate.  Borrower may prepay principal on any portion of this
              ----------                                                       
Note which bears interest determined in relation to the Prime Rate at any time,
in any amount and without penalty.

          (b) LIBOR.  Borrower may prepay principal on any portion of this Note
              -----                                                            
which bears interest determined in relation to Bank's LIBOR  at any time and in
the minimum amount of One Hundred  Thousand Dollars ($100,000); provided
however, that if the outstanding principal balance of such portion of this Note
is less than said amount, the minimum prepayment amount shall be the entire
outstanding principal balance thereof.  In consideration of Bank providing this
prepayment option to Borrower, or if any such portion of this Note shall become
due and payable at any time prior to the last day of the Fixed Rate Term
applicable thereto by acceleration or otherwise, Borrower shall pay to Bank
immediately upon demand a fee which is the sum of the discounted monthly
differences for each month from the month of prepayment through the month in
which such Fixed Rate Term matures, calculated as follows for each such month:
<PAGE>

Page 24


               (i)  Determine the amount of interest which would have accrued
                    ---------                                                
                    each month on the amount prepaid at the interest rate
                    applicable to such amount had it remained outstanding until
                    the last day of the Fixed Rate Term applicable thereto.

              (ii)  Subtract from the amount determined in (i) above the amount
                    --------                                                   
                    of interest which would have accrued for the same month on
                    the amount prepaid for the remaining term of such Fixed Rate
                    Term at Bank's LIBOR , as applicable, in effect on the date
                    of prepayment for new loans made for such term and in a
                    principal amount equal to the amount prepaid.

             (iii)  If the result obtained in (ii) for any month is greater than
                    zero, discount that difference by Bank's LIBOR  used in (ii)
                    above.

Borrower acknowledges that prepayment of such amount will result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities.  Borrower, therefore, agrees to pay the above-described prepayment
fee and agrees that said amount represents a reasonable estimate of the
prepayment costs, expenses and/or liabilities of Bank.  If Borrower fails to pay
any prepayment fee when due, the amount of such prepayment fee shall thereafter
bear interest until paid at a rate per annum four percent (4%) above the Prime
Rate in effect from time to time (computed on the basis of a 360-day year,
actual days elapsed).

D.   EVENTS OF DEFAULT:

     The occurrence of any of the following shall constitute an "Event of
Default" under this Note:

     (a) The failure to pay any principal, interest, fees or other charges when
due hereunder or under any contract, instrument or document executed in

     (c) The death or incapacity of any individual Borrower or Third Party
Obligor, or the dissolution or liquidation of any Borrower or Third Party
Obligor which is a corporation, partnership, joint venture or other type of

defined event of default, under any provisions of any contract, instrument or
document pursuant to which Borrower or any Third Party Obligor has incurred any
obligation for borrowed money, any purchase obligation, or any other liability

withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

              (xv)   to make all other determinations deemed necessary or

    6.  Limitation.  Neither the Plan nor any Option shall confer upon an
        ----------                                                       
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

    7.  Term of Plan.  The Plan shall become effective upon its adoption by the
        ------------                                                           
Board.  It shall continue in effect for ten (10) years, unless sooner terminated
under Section 14 of the Plan.

    8.  Term of Option.  The term of each Option shall be stated in the Option
        --------------                                                        
Agreement.

    9.  Option Exercise Price and Consideration.
        --------------------------------------- 

        (a)   Exercise Price.  The per share exercise price for the Shares to be
              --------------                                                    
issued pursuant to exercise of an Option shall be determined by the
Administrator.

        (b)   Waiting Period and Exercise Dates.  At the time an Option is
              ---------------------------------                           
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

        (c)   Form of Consideration.  The Administrator shall determine the
              ---------------------                                        
acceptable form of consideration for exercising an Option, including the method
of payment.  Such consideration may consist entirely of:

              (i)    cash;
 
              (ii)   check;

              (iii)  promissory note;

              (iv)   other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

              (v)    consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

                                      -5-
<PAGE>
 
              (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

              (vii)  such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws; or

              (viii) any combination of the foregoing methods of payment.

    10.  Exercise of Option.
         ------------------ 

         (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
              -----------------------------------------------               
granted hereunder shall be exercisable according to the terms of the Plan and
at such times and under such conditions as determined by the Administrator and
set forth in the Option Agreement. An Option may not be exercised for a
fraction of a Share.

              An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan.  Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised.  No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

              Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

         (b)  Termination of Relationship as a Service Provider.  If an
              -------------------------------------------------             
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within
such period of time as is specified in the Option Agreement, and only to the
extent that the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the
Option Agreement). In the absence of a specified time in the Option Agreement,
the Option shall remain exercisable for three (3) months following the
Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified by the
Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                                      -6-
<PAGE>
 
         (c)   Disability of Optionee.  If an Optionee ceases to be a Service
               ----------------------                                        
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement).  In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination.  If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan.  If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

         (d)   Death of Optionee.  If an Optionee dies while a Service Provider,
               -----------------                                                
the Option may be exercised within such period of time as is specified in the
Option Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquires the right to exercise the Option by bequest or inheritance,
but only to the extent that the Option is vested on the date of death.  In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination.  If, at
the time of death, the Optionee is not vested as to his or her entire Option,
the Shares covered by the unvested portion of the Option shall immediately
revert to the Plan.  The Option may be exercised by the executor or
administrator of the Optionee's estate or, if none, by the person(s) entitled to
exercise the Option under the Optionee's will or the laws of descent or
distribution.  If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

         (e)   Buyout Provisions.  The Administrator may at any time offer to
               -----------------                                          
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

    11.  Non-Transferability of Options.  Unless determined otherwise by the
         -------------------------------                                     
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.  If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

    12.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
         ------------------------------------------------------------------
         Asset Sale.
         ---------- 

         (a)   Changes in Capitalization.  Subject to any required action by the
               -------------------------                                        
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in 

                                      -7-
<PAGE>
 
the number of issued shares of Common Stock effected without receipt of
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 Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance 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.

         (b)   Dissolution or Liquidation.  In the event of the proposed
               --------------------------                               
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable.  In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

         (c)   Merger or Asset Sale.  In the event of a merger of the Company
               --------------------                                          
with or into another corporation, or the sale of substantially all of the
assets of the Company, each outstanding Option shall be assumed or an
equivalent option or right substituted by the successor corporation or a
Parent or Subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the Option, the
Optionee shall fully vest in and have the right to exercise the Option as to
all of the Optioned Stock, including Shares as to which it would not otherwise
be vested or exercisable. If an Option becomes fully vested and exercisable in
lieu of assumption or substitution in the event of a merger or sale of assets,
the Administrator shall notify the Optionee in writing or electronically that
the Option shall be fully vested and exercisable for a period of fifteen (15)
days from the date of such notice, and the Option shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option
shall be considered assumed if, following the merger or sale of assets, the
option or right confers the right to purchase or receive, for each Share of
Optioned Stock, immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received
in the merger or sale of assets by holders of Common Stock for each Share held
on the effective date of the transaction (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock to
be solely common stock of the successor corporation or its Parent equal in
fair market value to the per share consideration received by holders of Common
Stock in the merger or sale of assets.

    13.  Date of Grant.  The date of grant of an Option shall be, for all
         -------------                                                   
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is 

                                      -8-
<PAGE>
 
determined by the Administrator. Notice of the determination shall be provided
to each Optionee within a reasonable time after the date of such grant.

                                      -9-
<PAGE>
 
    14.  Amendment and Termination of the Plan.
         ------------------------------------- 

         (a)   Amendment and Termination.  The Board may at any time amend,
               -------------------------                                      
alter, suspend or terminate the Plan.

         (b)   Effect of Amendment or Termination.  No amendment, alteration,
               ----------------------------------                            
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

    15.  Conditions Upon Issuance of Shares.
         ---------------------------------- 

         (a)   Legal Compliance.  Shares shall not be issued pursuant to the
               ----------------                                             
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

         (b)   Investment Representations.  As a condition to the exercise of an
               --------------------------                                       
Option the Company may require the person exercising such Option  to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

    16.  Inability to Obtain Authority.  The inability of the Company to obtain
         -----------------------------                                         
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

    17.  Reservation of Shares.  The Company, during the term of this Plan, will
         ---------------------                                                  
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

                        INTERNATIONAL NETWORK SERVICES

                          CHANGE OF CONTROL AGREEMENT


     This Change of Control Agreement (the "Agreement") is made and entered into
by and between _______________________________________ (the "Employee") and
International Network Services (the "Company"), effective as of
___________________________________, 1998 (the "Effective Date").

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


     A.  It is expected that the Company from time to time will consider the
possibility of an acquisition by another company or other change of control.
The Board of Directors of the Company (the "Board") recognizes that such
consideration can be a distraction to Employee and can cause Employee to
consider alternative employment opportunities.  The Board has determined that it
is in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication and objectivity of Employee,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company.

     B.  The Board believes that it is in the best interests of the Company and
its shareholders to provide Employee with an incentive to continue his
employment and to motivate Employee to maximize the value of the Company upon a
Change of Control for the benefit of its shareholders.

     C.  The Board believes that it is imperative to provide Employee with
certain severance benefits upon Employee's termination of employment following a
Change of Control which provides Employee with enhanced financial security and
provides incentive and encouragement to Employee to remain with the Company
notwithstanding the possibility of a Change of Control.

     D.  Certain capitalized terms used in the Agreement are defined in Section
6 below.

     The parties hereto agree as follows:

     1.  Term of Agreement.  This Agreement shall terminate upon the date that
         -----------------                                                    
all obligations of the parties hereto with respect to this Agreement have been
satisfied.

     2.  At-Will Employment.  The Company and Employee acknowledge that
         ------------------                                            
Employee's employment is and shall continue to be at-will, as defined under
applicable law.  If Employee's employment terminates for any reason, including
(without limitation) any termination prior to a Change of Control, Employee
shall not be entitled to any payments, benefits, damages, awards or compensation
other than as provided by this Agreement, or as may otherwise be available in
<PAGE>
 
accordance with the Company's established employee plans and practices or
pursuant to other agreements with the Company.

     3.  Change of Control.  In the event of a Change of Control (as defined in
         -----------------                                                     
Section 6(c) below), the unvested portion of any stock option(s) and/or shares
of restricted stock held by Employee under any Company plan ("Unvested Awards")
shall vest and become exercisable as follows:  (i) Unvested Awards that are
scheduled to vest in full within twelve (12) months of the Change of Control
shall vest in full as of such Change of Control; (ii) Unvested Awards that are
scheduled to vest in full more than twelve (12) months after the Change of
Control shall accelerate and become vested as to all but the last twelve (12)
months thereof, which shall vest over the twelve (12)-month period beginning on
the date of the Change of Control, subject to Employee's continued employment
with the Company, except as otherwise provided herein.

     4.  Severance Benefits.
         ------------------ 

         (a) Involuntary Termination Other than for Cause; Voluntary
             -------------------------------------------------------
Termination for Good Reason; Death; Permanent and Total Disability.  If, within
- ------------------------------------------------------------------             
twelve (12) months following a Change of Control, Employee's employment is (i)
involuntarily terminated by the Company other than for Cause (as defined herein)
or (ii) voluntarily terminated by Employee for Good Reason (as defined herein),
then Employee shall receive the following severance benefits from the Company:

             (1) Lump-Sum Severance Payment. A cash payment in an amount equal
                 --------------------------
to one hundred percent (100%) of Employee's Annual Compensation (as defined
herein);

             (2) Continued Employee Benefits. One hundred percent (100%) 
                 ---------------------------
Company-paid health, dental and vision insurance coverage at the same level of
coverage as was provided to such employee immediately prior to the Change of
Control (the "Company-Paid Coverage"). If such coverage included Employee's
dependents immediately prior to the Change of Control, such dependents shall
also be covered at Company expense. Company-Paid Coverage shall continue until
the earlier of (i) twelve (12) months from the date of termination, or (ii) the
date upon which Employee and his dependents become covered under another
employer's group health, dental, vision, long-term disability or life insurance
plans that provide Employee and his dependents with comparable benefits and
levels of coverage. For purposes of Title X of the Consolidated Budget
Reconciliation Act of 1985 ("COBRA"), the date of the "qualifying event" for
Employee and his or her dependents shall be the date of the Employee's
termination.

             (3) Option and Restricted Stock Accelerated Vesting. One hundred
                 -----------------------------------------------             
percent (100%) of the unvested portion of any stock option or restricted stock
held by Employee granted to Employee under any Company plan prior to the Change
of Control shall automatically be accelerated in full so as to become completely
vested.

         (b) Timing of Severance Payments.  Any severance payment to which
             ----------------------------                                 
Employee is entitled under Section 4(a)(1) shall be paid by the Company to
Employee in cash and in full, not later than thirty (30) calendar days following
the Termination Date.
<PAGE>
 
         (c)   Voluntary Resignation other than for Good Reason; Termination
               -------------------------------------------------------------
For Cause; Death; Permanent and Total Disability.  If Employee's employment
- ------------------------------------------------                           
terminates (i) by reason of Employee's voluntary resignation other than for Good
Reason, (ii) by the Company for Cause, or (iii) due to Employee's death or
"permanent and total disability" (as such term is defined under Internal Revenue
Code Section 22(e)(3) or any successor provision), then Employee shall not be
entitled to receive severance or other benefits except for those (if any) as may
then be established under the Company's then existing severance and benefits
plans and practices or pursuant to other agreements with the Company.

         (d) Termination Apart from Change of Control.  In the event Employee's
             ----------------------------------------                          
employment is terminated for any reason, either prior to the occurrence of a
Change of Control or after the eighteen (18)-month period following a Change of
Control, then Employee shall be entitled to receive severance and any other
benefits only as may then be established under the Company's existing severance
and benefits plans and practices or pursuant to other agreements with the
Company.

     5.  Definition of Terms.  The following terms referred to in this Agreement
         -------------------                                                    
shall have the following meanings:

         (a) Annual Compensation.  "Annual Compensation" means an amount equal
             -------------------                                              
to the sum of Employee's (i) annual Company salary at the highest rate in effect
in the twelve months immediately preceding Employee's Termination Date, and (ii)
100% of Employee's annual target bonus as in effect immediately prior to the
Change of Control or, if greater, 100% of Employee's annual target bonus as of
the Termination Date.

             -----                                                    
dishonesty taken by Employee in connection with his responsibilities as an
employee and intended to result in substantial personal enrichment of Employee,

or a crime causing material harm to the Company, (iii) a willful act by Employee
which constitutes gross misconduct and which is injurious to the Company, or

         (c) Change of Control.  "Change of Control" means the occurrence of
             -----------------                                              
any of the following events:

             (i)   Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act) ("Beneficial
Owner"), directly or indirectly, of securities of the Company representing fifty
percent (50%) or more of the total voting power represented by the Company's
then outstanding voting securities;

             (ii)  A change in the composition of the Board occurring within a
two-year period, as a result of which fewer than a majority of the directors are

controls the Company or controls such surviving entity) at least fifty percent
(50%) of the total voting power represented by the voting securities of the
Company or such surviving entity or the entity that controls the Company or
controls such surviving entity outstanding immediately after such merger or
consolidation; or

express written consent, a material reduction of Employee's duties, title,
authority or responsibilities, relative to Employee's duties, title, authority
or responsibilities as in effect immediately prior to such reduction, or the
assignment to Employee of such reduced duties, title, authority or
responsibilities; provided, however, that a reduction in duties, title,
authority or responsibilities solely by virtue of the Company being acquired and
made part of a larger entity (as, for example, when the Chief Financial Officer
of International Network Services remains as such following a Change of Control
and is not made the Chief Financial Officer of the acquiring corporation) shall
not constitute "Good Reason"; (ii) without Employee's express written consent, a
material reduction, without good business reasons, of the facilities and
perquisites (including office space and location) available to Employee
immediately prior to such reduction; (iii) a reduction by the Company in the
base salary of Employee as in effect immediately prior to such reduction; (iv) a

reduction with the result that Employee's overall benefits package is materially
reduced; (v) the relocation of Employee to a facility or a location more than
thirty-five (35) miles from Employee's then present location, without Employee's
express written consent; (vi) any purported termination of Employee by the
Company which is not effected for total and permanent disability or for Cause,
or any purported termination for which the grounds relied upon are not valid; or
(vii) the failure of the Company to obtain the assumption of this agreement by
any successors contemplated in Section 7(a) below.

         (e) Termination Date.  "Termination Date" shall mean (i) if this
             ----------------                                            
Agreement is terminated by the Company for total and permanent disability,
thirty (30) days after notice of termination is given to Employee (provided that
Employee shall not have returned to the performance of Employee's duties on a
full-time basis during such thirty (30)-day period), (ii) if Employee's
employment is terminated by the Company for any other reason, the date on which
a notice of termination is given, provided that if within thirty (30) days after
the Company gives Employee notice of termination, Employee notifies the Company
that a dispute exists concerning the termination or the benefits due pursuant to
this Agreement, then the Termination Date shall be the date on which such
dispute is finally determined, either by mutual written agreement of the
parties, or a by final judgment, order or decree of a court of competent
jurisdiction (the time for appeal therefrom having expired and no appeal having
been perfected), or (iii) if the Agreement is terminated by Employee, the date
on which Employee delivers the notice of termination to the Company.

     6.  Successors.
         ---------- 

         (a) Company's Successors.  Any successor to the Company (whether
             --------------------                                        
direct or indirect and whether by purchase, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Agreement and agree expressly to
perform the obligations under this Agreement in the same manner 

                                      -5-
<PAGE>
 
and to the same extent as the Company would be required to perform such
obligations in the absence of a succession. For all purposes under this
Agreement, the term "Company" shall include any successor to the Company's
business and/or assets which executes and delivers the assumption agreement
described in this Section 7(a) or which becomes bound by the terms of this
Agreement by operation of law.

         (b) Employee's Successors.  The terms of this Agreement and all rights
             ---------------------                                             
of Employee hereunder shall inure to the benefit of, and be enforceable by,
Employee's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

     7.  Notice.
         ------ 

         (a) General.  Notices and all other communications contemplated by
             -------                                                       
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid.  In the case of Employee, mailed
notices shall be addressed to him at the home address which he most recently
communicated to the Company in writing.  In the case of the Company, mailed
notices shall be addressed to its corporate headquarters, and all notices shall
be directed to the attention of its Secretary.

         (b) Notice of Termination.  Any termination by the Company for Cause
             ---------------------                                           
or by Employee as a result of a voluntary resignation or an Involuntary
Termination shall be communicated by a notice of termination to the other party
hereto given in accordance with Section 8(a) of this Agreement.  Such notice
shall indicate the specific termination provision in this Agreement relied upon,
shall set forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination under the provision so indicated, and shall
specify the termination date (which shall be not more than 30 days after the
giving of such notice).  The failure by Employee to include in the notice any
fact or circumstance which contributes to a showing of Involuntary Termination
shall not waive any right of Employee hereunder or preclude Employee from
asserting such fact or circumstance in enforcing his rights hereunder.

     8.  Miscellaneous Provisions.
         ------------------------ 

         (a) No Duty to Mitigate.  Employee shall not be required to mitigate
             -------------------                                             
the amount of any payment contemplated by this Agreement, nor shall any such
payment be reduced by any earnings that Employee may receive from any other
source.

         (b) Waiver.  No provision of this Agreement shall be modified, waived
             ------                                                           
or discharged unless the modification, waiver or discharge is agreed to in
writing and signed by Employee and by an authorized officer of the Company
(other than Employee).  No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

                                      -6-
<PAGE>
 
         (c) Whole Agreement.  No agreements, representations or understandings
             ---------------                                                   
(whether oral or written and whether express or implied) which are not expressly
set forth in this Agreement have been made or entered into by either party with
respect to the subject matter hereof.  This Agreement represents the entire
understanding of the parties hereto with respect to the subject matter hereof
and supersedes all prior arrangements and understandings regarding same.

         (d) Choice of Law.  The validity, interpretation, construction and
             -------------                                                 
performance of this Agreement shall be governed by the laws of the State of
California.

         (e) Severability.  The invalidity or unenforceability of any provision
             ------------                                                      
or provisions of this Agreement shall not affect the validity or enforceability
of any other provision hereof, which shall remain in full force and effect.

         (f) Withholding.  All payments made pursuant to this Agreement will be
             -----------                                                       
subject to withholding of applicable income and employment taxes to the extent
required by law.

         (g) Counterparts.  This Agreement may be executed in counterparts,
             ------------                                                  
each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

         IN WITNESS WHEREOF, each of the parties has executed this Agreement,
in the case of the Company by its duly authorized officer, as of the day and
year set forth below.

                      Management's Discussion and Analysis
                of Financial Condition and Results of Operations


The following discussion contains forward-looking statements that involve risks
and uncertainties. The Company's actual results could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors, including those set forth below in "Future Results Subject to Risks"
and under "Risk Factors" in the Company's Annual Report on Form 10-K.

ANNUAL RESULTS OF OPERATIONS

Revenue

Substantially all of the Company's revenue is derived from fees for professional
services. The Company also derives revenue from electronic services; however,
such revenue has not been significant to date. Revenue was $44.1 million, $99.3
million and $169.7 million in fiscal 1996, 1997 and 1998, respectively,
representing increases over the prior fiscal year of 183.6%, 125.2% and 70.9%,
respectively. Revenue increased primarily due to an increase in the number and
size of professional services projects and secondarily due to an increase in
average billing rates per hour. One client accounted for approximately 17.0% of
revenue in fiscal 1996. No one client accounted for more than 10% of revenue in
fiscal 1997 or 1998.

Operating Expenses

Professional Personnel    Professional personnel expenses consist primarily of
compensation and benefits of the Company's employees engaged in the delivery of
professional services and electronic services. Professional personnel expenses
were $19.9 million, $44.8 million and $75.7 million in fiscal 1996, 1997 and
1998, respectively, representing increases over the prior fiscal year of 198.9%,
125.3% and 68.8%, respectively. These increases were attributable primarily to
an increase in the number of network systems engineers. The number of network
systems engineers included in professional personnel was 344, 651 and 1,053 at
the end of fiscal 1996, 1997 and 1998, respectively. Professional personnel
expenses were 45.1%, 45.2% and 44.6% of revenue in fiscal 1996, 1997 and 1998,
respectively. Professional personnel expenses were lower as a percent of revenue
in fiscal 1998 than fiscal 1996 and 1997 due primarily to an increase in billing
rates for professional services, and to a lesser extent, an increase in
electronic services revenue as a percent of sales.

Sales and Marketing    Sales and marketing expenses consist primarily of
compensation, including commissions and benefits of sales and marketing
personnel as well as outside marketing expenses. Sales and marketing expenses
were $8.0 million, $14.4 million and $23.5 million in fiscal 1996, 1997 and
1998, respectively, representing increases over the prior fiscal year of 107.9%,
80.7% and 62.6%, respectively. The increase in each year was due primarily to
the growth in the number of sales and marketing employees and to commissions
resulting from increased revenue. Sales and marketing expenses were 18.1%, 14.6%
and 13.8% of revenue in fiscal 1996, 1997 and 1998, respectively. The decreases,
on a percentage basis, were due primarily to leverage of the field management
organization and changes in compensation plans.

General and Administrative    General and administrative expenses consist of
expenses associated with executive staff, finance, corporate facilities,
information systems and human resources. General and administrative expenses
were $5.0 million, $13.4 million and $19.1 million in fiscal 1996, 1997 and
1998, 
<PAGE>
 
respectively, representing increases over the prior fiscal year of 167.1%,
166.1% and 42.2%, respectively. The increase in each year was due primarily to
the growth in the number of personnel necessary to support the Company's growth
in operations. General and administrative expenses were 11.5%, 13.5%, and 11.3%
of revenue in fiscal 1996, 1997 and 1998, respectively. The increase from fiscal
1996 to fiscal 1997 on a percentage basis was due primarily to expanding the
Company's infrastructure to support the growth in operations. The decrease from
fiscal 1997 to fiscal 1998 on a percentage basis was due primarily to the
leverage of infrastructure.

Other Costs    Other costs consist primarily of travel and entertainment,
certain recruiting and professional development expenses, field facilities,
depreciation, expensed equipment and supplies related to the delivery of
professional services and electronic services. Other costs also include research
and development expenses related to electronic services. Other costs were $6.4
million, $14.7 million and $26.5 million in fiscal 1996, 1997 and 1998,
respectively, representing increases over the prior fiscal year of 174.8%,
128.2% and 80.2%, respectively. Other costs increased each year due primarily to
increases in the number of professional personnel employed, and to a lesser
extent, to the costs of field offices. Other costs were 14.6%, 14.8%, and 15.6%
of revenue in fiscal 1996, 1997 and 1998, respectively. Other costs, as a
percent of revenue, increased primarily due to increases in recruiting,
professional development and travel and entertainment expenses. Research and
development expenses were $879,000, $1.4 million, and $1.7 million in fiscal
1996, 1997 and 1998, respectively. Research and development expenses were 2.0%,
1.4%, and 1.0% of revenue in fiscal 1996, 1997 and 1998, respectively. These
increases in absolute dollars were a result of the development of, and
enhancements to, the Company's electronic services.

Interest and Other, Net

Interest and other, net consists of interest income and expense. Interest income
consists primarily of interest on cash, cash equivalents, investments and notes
receivable from shareholders. Interest expense consists of interest associated
with bank borrowings. Interest expense was $108,000 and $85,000, in fiscal 1996
and 1997, respectively. Interest and other, net were $3,000, $1.1 million, and
$1.9 million in fiscal 1996, 1997 and 1998, respectively. The increase in fiscal
1997 to $1.1 million or 1.1% of revenue compared to $3,000 or less than 0.1% of
revenue in fiscal 1996 was due primarily to increases in funds available for
investment and the pay-off of all outstanding debt as a result of the Company
completing its initial public offering in September 1996. The increase in fiscal
1998 to $1.9 million was due primarily to an increase in funds available for
investment.

Provision for Income Taxes

The Company provides for income taxes using an asset and liability approach that
recognizes deferred tax assets and liabilities for expected future tax
consequences of temporary differences between the book and tax bases of assets
and liabilities. The effective tax rates for fiscal 1996, 1997 and 1998 were
39%, 39% and 40%, respectively. The Company's effective tax rates approximated
the combined federal and state statutory rates, net of federal benefits.

LIQUIDITY AND CAPITAL RESOURCES

Since inception, the Company has financed its operations primarily through a
combination of cash generated from operations, the sale of equity and debt
securities and bank borrowings. In September 1996, the Company completed its
initial public offering of 2,875,000 shares of Common Stock at $16 per share,
which resulted in net proceeds to the Company of approximately $41.7 million. At
June 30, 1998, the Company had $68.7 million in cash, cash equivalents and
investments. The Company had a revolving line of credit with a bank that
provided for borrowings up to $10 million which expired in August 1998. Advances
under the revolving line of credit bore interest at the bank's prime rate. As of
June 30, 1998, there were no borrowings under 
<PAGE>
 
the revolving line of credit, and the Company was in compliance with all
covenants and restrictions. In August 1998, the Company entered into an
unsecured revolving line of credit agreement with another bank which provides
for borrowings up to $10 million. Borrowings under the revolving line of credit
bear interest at the bank's prime rate less 1/2%. The credit facility expires in
February 2000 and contains customary covenants and restrictions.

Net cash provided by operations was $347,000, $4.5 million and $25.2 million in
fiscal 1996, 1997 and 1998, respectively. The increase in cash provided by
operations each year primarily reflects the Company's increased profitability
offset by increases in accounts receivable. Although the Company believes its
collections experience is within industry standards, the Company's inability to
collect for its services on a timely basis in the future could have a material
adverse effect on the Company's business, operating results and financial
condition. In fiscal 1998, cash provided by operations also resulted from
prepayments for services resulting in an increase in deferred revenue of $11.3
million. Net cash used in investing activities was $4.4 million, $29.1 million
and $27.9 million in fiscal 1996, 1997 and 1998, respectively. Cash used in
investing activities in fiscal 1997 and 1998 primarily reflected net investment
activity and, to a lesser extent, purchases of computer equipment and software.
Cash used in fiscal 1996 reflected purchases of equipment and software. Net cash
provided by financing activities in fiscal 1996 of $760,000 primarily reflected
borrowings under the Company's credit facility, which were principally offset by
repayments on long-term debt. Net cash provided by financing activities in
fiscal 1997 and 1998 of $43.2 million and $11.6 million, respectively, primarily
resulted from the issuance of Common Stock and a warrant to purchase Common
Stock.

The Company believes that existing cash and investment balances combined with
cash generated from operations and amounts available under the credit facility,
will be sufficient to meet its capital requirements for at least the next twelve
months. The Company may also utilize cash to acquire or invest in complementary
businesses or to obtain the right to use complementary technologies. The Company
may sell additional equity or debt securities or obtain additional credit
facilities. The sale of additional equity or convertible debt securities will
result in additional dilution to the Company's shareholders.

FUTURE RESULTS SUBJECT TO RISKS

Since professional services revenue is recognized by the Company only when
network systems engineers are engaged on client projects, the utilization of
network systems engineers is important in determining the Company's operating
results. In addition, a substantial majority of the Company's operating
expenses, particularly personnel and related costs, depreciation and rent, are
relatively fixed in advance of any particular quarter. As a result, any
underutilization of network systems engineers may cause significant variations
in operating results in any particular quarter and could result in losses for
such quarter. Factors which would cause such underutilization include: the
reduction in size, delay in commencement, interruption or termination of one or
more significant projects; the completion during a quarter of one or more
significant projects; the inability to obtain new projects; the overestimation
of resources required to complete new or ongoing projects; and the timing and
extent of training, weather related shut-downs, vacation days and holidays. The
Company's clients are generally able to reduce or cancel their use of the
Company's professional services without penalty and with little or no notice.
The Company generally provides services to clients without a long-term
commitment. The Company's revenue and earnings may also fluctuate from quarter
to quarter based on a variety of factors including the loss of key employees, an
inability to hire and retain sufficient numbers of network systems engineers and
account managers, reductions in billing rates, write-offs of billings, or
services performed at no charge as a result of the Company's failure to meet
it's client's expectations, competition, the development and introduction of new
services, decrease or slowdown in the growth of the networking industry as a
whole and general economic conditions. The Company's operating results may also
fluctuate based upon the ongoing market acceptance and the timing and size of
orders for electronic 

<PAGE>
 
services which are difficult to forecast. If an unanticipated order shortfall
for electronic services occurs, the Company's operating results could be
materially adversely affected, particularly because margins are higher on
electronic services than professional services. In addition, the Company plans
to continue to expand its operations based on sales forecasts by hiring
additional network systems engineers, account managers and other employees, and
adding new offices, systems and other infrastructure. The resulting increase in
operating expenses would have a material adverse effect on the Company's
operating results if revenue were not to increase to support such expenses.
Based upon all of the foregoing, the Company believes that quarterly revenue and
operating results may vary significantly in the future and that period-to-period
comparisons of its operating results are not necessarily meaningful and should
not be relied on as indications of future performance. Furthermore, it is likely
that in some future quarter the Company's revenue or operating results will be
below the expectations of public market analysts or investors. In such event,
the price of the Company's Common Stock would likely be materially adversely
affected.

The Company's future success will depend in large part on its ability to hire,
train and retain network systems engineers who together have expertise in a wide
array of network and computer systems and a broad understanding of the
industries the Company serves. Competition for network systems engineers is
intense, and there can be no assurance that the Company will be successful in
attracting and retaining such personnel. In particular, competition is intense
for the limited number of qualified managers and senior network systems
engineers. The Company has experienced, and may in the future experience, high
rates of turnover among its network systems engineers. Any inability of the
Company to hire, train and retain a sufficient number of qualified network
systems engineers could impair the Company's ability to adequately manage and
complete its existing projects or to obtain new projects, which, in turn, could
have a material adverse effect on the Company's business, operating results and
financial condition. The Company has experienced, and may in the future
experience increasing compensation costs for its network systems engineers. Any
inability of the Company to offset such increases in compensation of network
systems engineers through higher billing rates or reduction of other expenses to
offset such increases, could have a material adverse effect on the Company's
business, operating results and financial condition. In addition, any inability
of the Company to attract and retain a sufficient number of qualified network
systems engineers in the future could impair the Company's planned expansion of
its business.

The Company's future success will also depend in large part on the development
of new business by the Company's account managers, who solicit new business and
manage relationships with existing clients. As a result, the Company's success
will depend on its ability to attract and retain qualified account managers who
have an understanding of the Company's business and the industry it serves.
Competition for account managers is intense and the Company has experienced, and
may in the future experience, high rates of turnover among its account managers.
In addition, integration of new account managers into the Company's business can
be lengthy. Any inability of the Company to attract and retain a sufficient
number of account managers or to integrate new account managers into the
Company's operations on a timely basis, would impair the Company's ability to
obtain projects from new and existing clients which could have a material
adverse effect on the Company's business, operating results and financial
condition.

Furthermore, the network services industry is comprised of a large number of
participants and is subject to rapid change and intense competition. With
respect to professional services, the Company faces competition from system
integrators, value added resellers ("VARs"), local and regional network services
firms, telecommunications providers, network equipment vendors, software vendors
and computer systems vendors, many of which have significantly greater
financial, technical and marketing resources and greater name recognition, and
generate greater service revenue than does the Company. With respect to
electronic services, the Company faces competition primarily from software
vendors. The Company has faced, and 
<PAGE>
 
expects to continue to face, additional competition from new entrants into its
markets. Increased competition could result in price reductions, fewer client
projects, underutilization of employees, reduced operating margins and loss of
market share, any of which could materially adversely affect the Company's
business, operating results and financial condition. There can be no assurance
that the Company will be able to compete successfully against current or future
competitors. The failure of the Company to compete successfully would have a
material adverse effect on the Company's business, operating results and
financial condition.

In addition, the Company has a significant relationship with Cisco Systems
("Cisco") and believes that maintaining and enhancing this relationship is
important to the Company's business. Although the Company believes that its
relationship with Cisco is good, there can be no assurance that the Company will
be able to maintain or enhance its relationship with Cisco. Any deterioration in
the Company's relationship with Cisco could have a material adverse effect on
the Company's business, operating results and financial condition.

Year 2000

The year 2000 problem is the result of computer programs being written using two
digits rather than four to define the applicable year. Computer programs that
have time-sensitive software may recognize a date using "00" as the year 1900
rather than the year 2000. This could result in a major system failure or
miscalculations. The year 2000 issue creates risk for the Company from
unforeseen problems in its own computer systems and from third parties. Failure
of the Company's and/or third parties' computer systems could have a material
adverse impact on the Company's ability to conduct its business. The Company is
currently reviewing its products, its internal computer systems and systems of
third parties on which the Company relies for handling the year 2000. Based on
information available to date, the Company believes that it will be able to
complete its year 2000 compliance review and make any necessary modifications to
its products and internal systems prior to the end of 1999. The Company further
believes that such review and modification, if any, will not require the Company
to incur any material charge to operating expenses over the next several years.
The Company is also seeking confirmation from third parties that their systems
are year 2000 compliant or that plans are being developed to address the year
2000 problem. However, there can be no assurance that such third-party systems
will be year 2000 compliant or that the failure of such systems to be year 2000
compliant would not have a material adverse effect on the Company's financial
position or results of operations. The Company believes its current electronic
service offering, EnterprisePro, is year 2000 compliant.

Market Risk

The Company invests in marketable securities in accordance with its investment
policy. The primary objectives of the Company's investment policy are to
preserve principal, maintain proper liquidity to meet operating needs and
maximize yields. The Company's investment policy specifies credit quality
standards for the Company's investments and limits the amount of credit exposure
to any single issue, issuer or type of investment. The maximum allowable
maturity of a single issue is two years and the maximum allowable average
maturity of the portfolio is one year.

At the end of fiscal 1998, the Company had an investment portfolio of fixed
income securities totaling $40.5 million, excluding those classified as cash and
cash equivalents. The Company's investments consist primarily of money market
funds and various municipal obligations. These securities are classified as
available for sale and are recorded on the balance sheet at fair market value
with unrealized gains or losses reported as a separate component of
shareholders' equity. Unrealized losses are charged against income when a
decline in fair market value is determined to be other than temporary. The
specific identification method is used to determine the cost of securities sold.
Gains and losses on marketable securities are included in net interest income
when realized.
<PAGE>
 
The investment portfolio is subject to interest rate risk and will fall in value
in the event market interest rates increase. If market interest rates were to
increase immediately and uniformly by 50 basis points (approximately 10% of
current rates in the portfolio) from levels as of June 30, 1998, the fair market
value of the portfolio would decline by approximately $200,000. However, the
Company has the ability to hold its fixed income securities to maturity and may
avoid recognizing a decline in income or cash flows.

To date, revenue from foreign sources and operations in foreign locations have
not been material. In addition, substantially all of the revenue has been
received in U.S. dollars. As such, the current foreign exchange rate risk is
considered minimal, and the Company believes that sudden significant changes in
foreign currency exchange rates would not have a material impact on its
operating results or financial position. However, a component of the Company's
long-term strategy is to expand into international markets. As a result,
fluctuations in currency exchange rates in the future could have a material
adverse effect on the Company's business, operating results and financial
condition.

                   Notes to Consolidated Financial Statements

1. THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES

The Company

International Network Services (the "Company") was incorporated in California in
August 1991. The Company is a leading provider of services for complex
enterprise networks. The Company provides services for the full life cycle of a
network and maintains expertise in the most complex network technologies and
multivendor environments. The Company operates in one industry segment. To date,
the Company has provided limited professional services to certain of its United
States based clients in foreign locations.

Significant accounting policies

Fiscal year    The Company's fiscal year is composed of four 13-week quarters,
each of which ends on the last Sunday of the final fiscal month of the quarter,
with the fiscal year ending on the Sunday closest to June 30. For financial
statement presentation purposes, each fiscal year end is titled June 30th.

Principles of consolidation    The consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiaries in the United Kingdom
and Canada. All intercompany accounts and transactions have been eliminated.

Foreign currency translation    The functional currency of the Company's wholly-
owned foreign subsidiaries are the local currencies. Assets and liabilities of
these subsidiaries are translated into U.S. dollars at exchange rates in effect
at the balance sheet date. Income and expense items are translated at average
exchange rates for the period. Accumulated net translation adjustments are
recorded in shareholders' equity. Foreign exchange transaction gains and losses
were not material in all periods presented and are included in the results of
operations.

Cash equivalents and marketable securities    Cash equivalents consist of highly
liquid investments with original maturities of three months or less. The
company's marketable securities are classified as available-for-sale and, at the
balance sheet date, are reported at fair market value which approximates cost.

Property and equipment    Property and equipment are stated at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of the respective assets, ranging from two to five years.

Revenue recognition    Substantially all of the Company's revenue is derived
from professional services which are generally provided to clients on a "time
and expenses" basis. Revenue is recognized as services are performed. Payments
received in advance of services performed are recorded as deferred revenue. The
Company also performs a limited number of fixed-price engagements under which
revenue is recognized using the percentage-of-completion method (based on the
ratio of costs incurred to total estimated project costs). Provision for
estimated losses on engagements is made during the period in which the loss
becomes probable and can be reasonably estimated. To date, such losses have been
insignificant. The Company reports revenue net of reimbursable expenses which
are billed to and collected from clients. The Company also derives revenue from
electronic services. Prior to the quarter ended September 30, 1997, the Company
offered its electronic services to clients only as a service which resulted in
revenue recognition over the contract term. The Company currently allows clients
to separately purchase a software license, software subscription and support
services as an alternative to the service contract. When the client purchases
electronic services in components, the Company recognizes service and software
subscription revenue over the term of the contract, installation revenue when
installation is complete and software license revenue when software is shipped,
there are no significant obligations remaining, and collection is probable.
<PAGE>
 
Operating expenses

Professional personnel    Professional personnel expenses consist primarily of
compensation and benefits of the Company's employees engaged in the delivery of
professional and electronic services.

Other costs    Other costs consist primarily of travel and entertainment,
certain recruiting and professional development expenses, field facilities,
depreciation, expensed equipment and supplies related to the delivery of
professional services and electronic services. Other costs also include research
and development expenses related to electronic services. Research and
development expenses were $1.7 million, $1.4 million, and $879,000 for fiscal
years 1998, 1997 and 1996, respectively. All research and development expenses,
including software development costs, are charged to expense as incurred.
Statement of Financial Accounting Standards No. 86 ("SFAS 86"), "Accounting for
the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed,"
requires the capitalization of certain software development costs once
technological feasibility is established, which the Company defines as the
completion of a working model. The capitalized costs are then amortized on a
straight line basis over the estimated product life, or based on the ratio of
current revenues to total projected product revenues, whichever is greater. To
date, costs incurred subsequent to achieving technological feasibility and prior
to the general commercial release of the electronic services have not been
significant. Accordingly, the Company has not capitalized any software
development costs.

Income taxes

The Company provides for income taxes using an asset and liability approach that
recognizes deferred tax assets and liabilities for expected future tax
consequences of temporary differences between the book and tax bases of assets
and liabilities.

Concentration of credit risk

The Company's financial instruments that are exposed to concentrations of credit
risk consist primarily of cash, cash equivalents, short-term and long-term
investments, and accounts receivable. The Company's investments consist of
investment grade securities managed by qualified professional investment
managers. The investment policy limits the Company's exposure to concentration
of credit risk. The Company's accounts receivable is derived from revenue earned
from customers primarily located in the United States. The Company maintains an
allowance for potential credit losses based upon the expected collectibility of
all accounts receivable; historically, such losses have been immaterial. In
fiscal 1998 and 1997, no one customer accounted for more than 10% of revenues.
In fiscal 1996, one customer accounted for 17% of revenue.

Net income per share

Basic net income per share is computed by dividing net income available to
common shareholders (numerator) by the weighted average number of common shares
outstanding (denominator) during the period and excludes the dilutive effect of
stock options. Diluted net income per share gives effect to all dilutive
potential common shares outstanding during a period. In computing diluted net
income per share, the average stock price for the period is used in determining
the number of shares to be purchased from the exercise of stock options. All
prior period net income per share data presented has been restated in accordance
with Statement of Financial Accounting Standards No. 128 ("SFAS 128"), "Earnings
per Share."

The following is a reconciliation of the numerators and denominators of the
basic and diluted earnings per share ("EPS") computations for the years ended
June 30 (in thousands):

                                ====================================================================================================
</TABLE>

Antidilutive Options    Options to purchase 380,883, 151,141 and 30,593 shares
of common stock were outstanding during fiscal 1998, 1997 and 1996,
respectively, but were not included in the computations of diluted EPS because
the options' exercise price was greater than the average market price of the
common shares.

Stock-based compensation

The Company accounts for stock-based compensation using the intrinsic value
method prescribed by APB Opinion No. 25, "Accounting for Stock Issued to
Employees." The Company's policy is to grant options with an exercise price
equal to the quoted market price of the Company's stock on the grant date.
Accordingly, no compensation cost has been recognized in the Company's
consolidated statements of income. The Company has provided additional pro forma
disclosures as required under Statement of Financial Accounting Standards No.
123 ("SFAS 123"), "Accounting for Stock-Based Compensation" (see Note 6).

Management estimates and assumptions

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, the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenue and expenses during the reporting period. Actual
results could differ from those estimates.

Recently issued accounting pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
Income," which establishes standards for reporting and displaying comprehensive
income and its components in a full set of general-purpose statements. The
disclosure requirements of SFAS 130 are first expected to be reflected in the
Company's first quarter of fiscal 1999 interim statements. In June 1997, the
FASB issued Statement of Financial Accounting Standards No. 131 ("SFAS 131"),
"Disclosures about Segments of an Enterprise and Related Information," which
establishes annual and interim reporting standards for an enterprise's business
segments and related disclosures about its products, services, geographic areas
and major customers. SFAS 131 will be first reflected in the Company's fiscal
1999 Annual Report. Adoption of SFAS 130 and SFAS 131 will not impact the
Company's consolidated financial position, results of operations or cash flows.
<PAGE>
 
In October 1997 and March 1998, the American Institute of Certified Public
Accountants (AICPA) issued Statement of Position (SOP) 97-2, "Software Revenue
Recognition" and 98-4, "Deferral of Effective Date of a Provision of SOP 97-2,
Software Revenue Recognition," which the Company is required to adopt for
transactions entered into in the fiscal year beginning July 1, 1998. SOP 97-2
and SOP 98-4 provide guidance on recognizing revenue on software transactions
and supercede SOP 91-1. The Company believes that the adoption of SOP 97-2 and
SOP 98-4 will not have a significant impact on its current licensing or revenue
recognition practices.

In April 1998, the AICPA issued SOP 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." SOP 98-1 provides guidance for
determining whether computer software is internal-use software and on accounting
for the proceeds of computer software originally developed or obtained for
internal use and then subsequently sold to the public. It also provides guidance
on capitalization of the costs incurred for computer software developed or
obtained for internal use. The Company is required to adopt SOP 98-1 by July 1,
2000 and does not expect it to have a material effect on the Company's
consolidated financial position, results of operations or cash flows.

Gross realized gains and losses from the sale of securities classified as
available-for-sale were not material for the years ended June 30, 1998, 1997 and
1996. For the purpose of determining gross realized gains and losses, the cost
of securities is based upon specific identification.

At June 30, 1998, marketable securities totaling $26.5 million were classified
as cash equivalents and included money market funds of $10.3 million and
municipal bonds of $16.2 million. At June 30, 1997, marketable securities
totaling $12.9 million were classified as cash equivalents and included money
market funds of $.9 million and municipal bonds of $12.0 million.

4. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK

Prior to the initial public offering in September 1996, the Company had
authorized 17,000,000 shares of Mandatorily Redeemable Convertible Preferred
Stock ("Preferred Stock"), of which 2,848,000, 6,849,000 and 7,037,967 shares
were designated as Series A, B and C, respectively. The Preferred Stock was
mandatorily redeemable anytime after May 19, 1998, at a per share price equal to
the original issue price plus a 10% accretion per year, compounded annually.
Accretion of Preferred Stock was $270,000 and $1.1 million in fiscal 1997 and
1996, respectively. All issued and outstanding shares of Preferred Stock were
converted into 16,734,889 shares of Common Stock upon the closing of the public
offering.

5. COMMON STOCK

Certain Common Stock option holders (see Note 6) have the right to exercise
unvested options, subject to a repurchase right held by the Company. At June 30,
1998, 549,992 of the shares issued on the exercise of options were subject to
repurchase by the Company at the original purchase price in the event of
employee termination.

In September 1996, the Company completed its initial public offering of
2,875,000 shares of Common Stock at $16 per share, which resulted in net
proceeds to the Company of approximately $41.7 million.

During 1998, in conjunction with a services agreement with a client, the Company
received aggregate proceeds of approximately $3.2 million from the client for a
warrant to purchase up to 263,000 shares of Common Stock at $29.59 per share.
The warrant, which is exercisable immediately, expires on May 1, 2005. The
warrant was issued at fair market value.

At June 30, 1998, the Company had reserved 263,000, 565,276, and 9,895,802
shares of Common Stock for future issuance under a warrant purchase agreement,
its stock purchase plan and its stock option plans, respectively.

Notes receivable from shareholders
In exchange for the issuance of Common Stock upon exercise of options, the
Company has from time to time received notes receivable from shareholders which
bear interest at rates varying from 5.33% to 5.91% per annum. Principal and
interest are due and payable at different dates between 1998 and 1999. The
outstanding balance of such notes receivable has been included in shareholders'
equity.

6. EMPLOYEE BENEFIT PLANS

Stock option plan
On July 18, 1996, the Company's Board of Directors adopted the 1996 Stock Option
Plan (the "1996 Plan") as a successor to its 1992 Stock Option Plan (the "1992
Plan"). In addition to the 8,000,000 shares of Common Stock authorized for
issuance under the 1992 Plan, the Board of Directors authorized an additional
5,500,000 shares for issuance under the 1996 Plan. As of July 18, 1996, no
further option grants or stock issuances were made under the 1992 Plan, and all
option grants and stock issuances made during the remainder of fiscal 1997 were
made under the 1996 Plan. All outstanding options under the 1992 Plan were
incorporated into the 1996 Plan. The 1996 Plan provides for granting to
employees (including officers and directors) incentive stock options and for the
granting to employees, directors (including non-employee directors) and
consultants nonstatutory stock options and stock purchase rights.

On April 24, 1998, the Company's Board of Directors adopted the 1998
Nonstatutory Stock Option Plan (the "1998 Plan") and authorized 2,000,000 shares
for issuance under this plan. The 1998 Plan provides for granting nonstatutory
stock options to employees and consultants, excluding officers and directors.

Incentive stock options must be granted at fair market value at the date of
grant, and nonstatutory stock options and stock appreciation rights may be
granted at not less than 85% of fair market value on the date of grant. Options
generally vest 24% on the first anniversary from the date of grant, and ratably
each month over the remaining thirty-eight months. Options expire over terms not
exceeding ten years from the date of grant.

On April 25, 1997, the Board of Directors approved a plan to offer all
employees, excluding Executive Officers, the opportunity to exchange their
outstanding stock options with exercise prices greater than $23.00 per share for
new options that would be exercisable at the fair market value of the Company's
Common Stock as of the closing of the stock market on May 5, 1997 ($19.75).
These new options were otherwise identical to the old options.

Employee stock purchase plan

On July 18, 1996, the Company's Board of Directors adopted an Employee Stock
Purchase Plan (the "Purchase Plan"), which was approved by shareholders in
September 1996. Under the Purchase Plan, eligible employees can have up to 15%
of their earnings withheld through payroll deductions for the purchase of shares
of Common Stock at 85% of the lower of the fair market value of the Common Stock
on the commencement date of each offering period or the specified purchase date.
Each offering period is divided into four consecutive semi-annual purchase
periods. The initial offering period commenced on the effectiveness of the
Company's initial public offering in September 1996. A total of 1,200,000 shares
of Common Stock have been reserved for issuance under the Purchase Plan. There
were 419,367 and 215,357 shares issued under the Purchase Plan in fiscal 1998
and 1997, respectively.

Stock-based compensation

At June 30, 1998, the Company has three stock-based compensation plans, as
described above. The Company has elected to continue to apply APB Opinion 25 and
related Interpretations in accounting for its plans (see Note 1). Accordingly,
no compensation cost has been recognized for the 1992, 1996 and 1998 Plans or
Purchase Plan. Pro forma information regarding net income and earnings per
share is required by SFAS 123 for awards granted after June 30, 1994, as if
the Company had accounted for its stock-based awards to employees under the
fair value method of SFAS 123. The fair value of the Company's stock-based
awards to employees was estimated using a Black-Scholes option pricing model.
The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options 
<PAGE>
 
that have no vesting restrictions and are fully transferable. The Black-
Scholes model requires the input of highly subjective assumptions including
the expected stock price volatility. Because the Company's stock-based awards
to employees have characteristics significantly different from those of traded
options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the
existing models do not necessarily provide a reliable single measure of the
fair value of its stock-based awards to employees. The fair value of the
Company's stock-based awards to employees was estimated assuming no expected
dividends and the following weighted-average assumptions:

                                   Options                Purchase Plan
                            1998     1997     1996        1998      1997
 ------------------------------------------------------------------------
 Expected life (years)      4.50      4.50     4.50       0.50      0.50
 Expected volatility          55%       55%      55%        70%       75%
 Risk-free interest rate    5.47%     6.32%    5.92%       5.23%    5.82%
 Dividend yield               --        --       --          --       --


The weighted average estimated fair value of options granted under the 1998,
1996 and 1992 Plans during 1998, 1997 and 1996 was $12.48, $8.23 and $0.81,
respectively. The weighted average estimated fair value of purchase rights
granted under the Purchase Plan during 1998 and 1997 was $7.94 and $7.65,
respectively. For pro forma purposes, the estimated fair value of the Company's
stock-based awards to employees is generally amortized over the options' vesting
period (for options) and the six-month purchase period (for stock purchases
under the Purchase Plan). The Company's pro forma information follows:

Deferred income taxes reflect the tax effects of temporary differences between
carrying amounts of assets and liabilities for financial reporting and income
tax purposes. The Company provides a valuation allowance for deferred tax
assets when it is more likely than not, based on available evidence, that some
portion or all of the deferred tax assets will not be realized. Based on a
reevaluation of the realizability of future tax benefits based on income
earned in fiscal 1996, creating available tax carrybacks, the Company reversed
the previously established valuation allowance during fiscal 1996. Significant
components of the Company's deferred tax assets are as follows (in thousands):

Total rent expense for the years ended June 30, 1998, 1997 and 1996 was
approximately $3.0 million, $1.3 million, and $545,000, respectively.

During 1998, the Company entered into an agreement with a client under which the
Company is required to pay royalties to the client, if and when revenue from
specified services exceeds a predetermined base of revenue for those services.
No royalties have been recorded under this agreement in fiscal 1998.

9. LINES OF CREDIT

The Company had a $10 million line of credit with a bank which expired in August
1998. Borrowings under the line of credit bore interest at the bank's prime rate
(8.5% at June 30, 1998). There were no borrowings under the line of credit at
June 30, 1998. The line of credit was secured by substantially all of the
Company's assets and required the Company to comply with certain financial
covenants. At June 30, 1998, the Company was in compliance with these financial
covenants.

In August 1998, the Company entered into an unsecured revolving line of credit
agreement with another bank which provides for borrowings up to $10 million.
Borrowings under the revolving line of credit bear interest at the bank's prime
rate less 1/2%, or the Company has the option to borrow at a fixed rate at 
1 1/2% above the bank's LIBOR for a fixed term of up to three months. Balances
outstanding at February 14, 2000 that have been used to fund capital equipment
may be converted to a 3-year term loan which provides for the same interest rate
options. The line of credit expires in February 2000 and requires the Company to
comply with certain financial convenants.

                       Report of Independent Accountants



TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
INTERNATIONAL NETWORK SERVICES

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of
International Network Services and its subsidiaries at June 30, 1998 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended June 30, 1998, in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.
